Description

Field of technology

[0001] The present invention relates to a device for processing laundry.

State of the art

[0002] In general, a laundry treatment device refers to a device that performs a series of processes (such as washing, drying, deodorizing, removing wrinkles, etc.) on laundry. The term "laundry treatment device" may include a washing machine for washing laundry, a dryer for drying wet laundry, and a freshener for removing odors or wrinkles from laundry.

[0003] Meanwhile, the trend of creating laundry treatment devices is aimed at creating a single device designed to perform washing, drying, deodorizing, and removing wrinkles from laundry. However, existing laundry treatment devices are limited in deodorizing laundry or removing wrinkles from laundry due to the use of a drum for placing laundry and a drive for rotating the drum.

[0004] In order to solve the problem related to the “laundry treating apparatus” shown in Fig. 1 and disclosed in Korean Patent Application Laid-Open Publication No. 10-2009-0124596, the laundry treating apparatus comprises an inner case 200 having a receiving area for hanging laundry, a hot air supply device (not shown) supplying hot air or moisture from a lower portion of the inner case, and a body 100 disposed on the outer side of the inner case and the hot air supply device to form an external appearance.

[0005] The laundry treatment device of the prior art may supply hot air to a hot air supply device (not shown) located under the body, or deodorize the laundry and simultaneously remove wrinkles from the laundry by creating pressure on the laundry in a position in which the laundry is suspended in a placement area formed in the inner casing 200. Thus, in a position in which the laundry is spread inside the body under the action of the load of its own weight, hot air or moisture can be supplied to the laundry to deodorize the laundry and remove wrinkles from the laundry without a separate unit.

[0006] In the laundry processing apparatus of the prior art, a frame 10 is installed for fixing the shapes of the inner casing 200, the hot air supply device and the body 100 and ensuring durability. The frame 10 includes a plurality of vertical frames 11 arranged in the height direction and a plurality of horizontal frames 12 connecting the vertical frames to each other in the width direction, as a result of which the inner casing 200 can be stably accommodated therein and the vibration generated by the hot air supply device (not shown) and the like can be effectively supported.

[0007] However, the prior art laundry treatment device has a disadvantage during the manufacturing process in that the horizontal frames 12 are assembled with the vertical frames 11, the inner casing 200 and the hot air supply device are fixed on the assembled frame 10, and the body 100 must be connected again to the frame 10. In particular, if the body 100 comprises a side surface 120, a rear surface 110 and an upper surface 101, then the disadvantage arises in that each element must be connected to the frame 10.

[0008] In addition, there is a disadvantage in that assembly of connecting members such as 120 bolts or nuts or more is required when the inner casing and the body are connected to each other and also when the frame 10 is assembled.

[0009] Therefore, it takes a long time to manufacture the laundry treating device, and the defect rate increases because the durability of the laundry treating device cannot be ensured if a specific connecting member is excluded or not fully secured.

[0010] In addition, even if the frame is considered to be replaced by a foaming agent, the shape changes or the internal area is not sufficiently provided when the foaming agent is cured, or it is difficult to maintain the rigidity. For this reason, there is a problem that it is difficult to use the foaming agent in the actual product.

[0011] In addition, the prior art laundry processing device has a disadvantage in that the body is formed relatively higher than other household devices, and is easily bent under the action of an external force.

Technical task

[0012] An object of the present invention is to provide a laundry processing device that can eliminate the assembly process by fixing the internal elements using a foaming agent or a foam insulator (hereinafter referred to as a foaming agent).

[0019] Furthermore, another object of the present invention is to provide a laundry processing apparatus that can maintain the shape of the body even if the foaming agent expands when it solidifies in the body.

[0020] Furthermore, another object of the present invention is to provide a laundry processing apparatus that can reduce the frequency of defects by replacing the frame with a foaming agent.

[0021] Furthermore, another object of the present invention is to provide a laundry processing apparatus that can ensure durability by ensuring uniform filling of the foaming agent.

The best way to implement an invention

[0079] Reference will be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts, and the description thereof will be replaced by the first description. The term "singular" in this description should be understood to include the plural as well as the singular, unless the context otherwise specifies. Furthermore, in the description of an embodiment disclosed in the present description, if a detailed description of elements or functions known with respect to the present invention unnecessarily obscures the subject matter of the present invention, the detailed description will be omitted. Furthermore, it should be understood that the accompanying drawings are intended to easily understand the embodiment disclosed in the present description, and the technical subject matter disclosed in the present description should not be limited to the accompanying drawings.

[0080] Fig. 2 is a structural view of a laundry processing apparatus according to the present invention.

[0081] As shown in Fig. 2(a), the laundry treating apparatus according to the present invention comprises a body 100 having an opening 130 in a forward direction, a door 180 arranged to be pivoted in front of the opening to open or close the opening, an inner casing 200 arranged in the body, forming a placement area in which the laundry is placed, and a hot air supply device 400 arranged on one side of the inner body, supplying one or more of hot air and moisture to the placement area.

[0082] The door 180 may be configured to seal the opening 130 and direct hot air or moisture supplied to the placement area to fully expose the laundry without leaking out.

[0083] A hanging unit 300 for hanging laundry or uniformly exposing the laundry to hot air or moisture by treating the laundry may be located on the upper portion of the inner casing 200.

[0084] The hanging unit 300 may include a hanging rod 310 connected to the upper surface of the inner casing 200 for hanging the laundry, and a processing unit 320 vibrating the hanging rod 310.

[0085] The processing unit 320 may include an electric motor vibrating the suspension rod 310 and a transmission device connected to the suspension rod 310 for transmitting the power of the electric motor to the suspension rod 310, and may be made in any shape that can vibrate the suspension rod 310.

[0086] Since the hot air supply device 400 generates hot air having a density that is relatively low, the hot air supply device 400 is preferably located at a lower portion of the inner casing 200 to easily supply hot air to the laundry.

[0087] In addition, one or more communication openings 212 communicating with the hot air supply device 400 may be formed on the lower surface of the inner casing 200. In detail, the communication openings 212 may be formed in a plurality, wherein any one communication opening 212a may be configured to discharge hot air, and another communication opening 212b may be configured to allow hot air to be discharged into the hot air supply device 400 after performing refreshing such as drying, wrinkle removal and deodorizing of laundry.

[0088] As shown in Fig. 2(b), the hot air supply device 400 may include a heat pump 450 supplying one or more of hot air and moisture to a accommodating area, and a accommodating body 410 located at a lower portion of the accommodating area for accommodating the heat pump 450. The accommodating body may include an inlet for communication 401 (see Fig. 3) communicating with the communication opening 212 for supplying air to the heat pump 450 or discharging hot air supplied by the heat pump 450 to the accommodating area.

[0089] The housing 410 may include a through section 420 configured to allow the heat pump 450 to be opened in one of the forward direction or the rear direction. In this case, the user can easily approach the heat pump 450 and the like by opening only the door 180.

[0090] In addition, for the convenience of arranging and servicing the heat pump 450, the hot air supply device 400 may further include a discharge unit 460 for removing the heat pump 450 to the outer side of the through section 420 while supporting the heat pump 450, and a guide 413 located on the inner side of the housing 410 for guiding the removal or insertion of the discharge unit 460.

[0091] Therefore, the user can remove the heat pump 450 from the housing 100 for easy maintenance and repair of the heat pump 450, and the heat pump 450 can be manufactured separately, and then the hot air supply device 400 can be arranged in a modular manner.

[0092] The discharge unit 460 may be formed in the form of a plate or may be formed in the shape of an ‘L’ to protect the discharge opening 190 formed on the rear surface of the housing.

[0093] The guide 413 may be in the form of a roller or a rail that can support and guide the unloading unit 460.

[0094] The heat pump 450 may include an evaporator that cools air from a location area to condense moisture contained in the air, a compressor that compresses and heats a refrigerant that has passed through the evaporator, a condenser that generates hot air by heating the cooled air using a refrigerant discharged into the compressor, and a valve that reduces the temperature by expanding the refrigerant that has passed through the condenser.

[0095] In addition, the heat pump 450 may further include a steam generator that generates steam or mist in the area in which the air moves, and may further include a fan that provides power for circulating the hot air.

[0096] Although not shown, the heat pump 450 may include a movable duct that can supply air housed in the inner casing 200 to the inner casing 200 by passing through the evaporator and the condenser without leakage, and the movable duct may be configured to communicate with the inlet 401 for communication, and a fan may be located in the movable duct.

[0097] Fig. 3 shows a structure in which the laundry treatment device of the present invention can be implemented using a foam generator by eliminating the frame.

[0098] As shown in Fig. 3, the body 100 may be formed into a box shape, and the inner casing 200 and the hot air supply device 400 may be connected to each other and fixed by insertion into the opening 130.

[0099] After this, the foaming agent can be inserted through the rear surface of the housing 100 and thus can be filled in the housing 100 and the outer region of the inner housing 120 and the hot air supply device 400.

[00100] The foaming agent may be made of a liquefied foamed insulating material. The foaming agent may be inserted into the housing 100 and filled in the region formed by the inner casing 200, the hot air supply device 400 and the housing 100, and may then be cooled and hardened over time.

[00101] Therefore, the foaming agent can fix the positions of the inner casing 200 and the hot air supply device 400 when in contact with the outer surfaces of the inner casing 200 and the hot air supply device 400 and the inner surface of the body 100. In addition, the foaming agent can maintain the shape of the body 100 when filled in the area inside the body 100, and can absorb external impact or vibration to a certain extent to ensure durability even if external impact or vibration occurs.

[00102] As a result, since the laundry treating apparatus 10 of the present invention can fix the inner casing 200 and the hot air supply device 400 even if the frame 10 is eliminated, the process of assembling connecting members such as bolts and nuts can be eliminated, as a result of which the overall weight of the laundry treating apparatus can be reduced.

[00103] In addition, since the inner casing 200 and the hot air supply device 400 are insulated, energy leakage can be prevented to maximize efficiency. Even if the user is near the laundry treating device 10 during operation of the laundry treating device 10, the user may not experience discomfort due to heat, and an injury such as a burn caused by carelessness can be prevented.

[00104] In this case, even if the foaming agent can be inserted into the housing 100 and then filled into the inner region of the housing 100, the foaming agent must be prevented from leaking until the foaming agent hardens.

[00105] For this purpose, the inner casing 200 may include an inner body 210 located in front of the accommodation area, having an inlet 211 through which laundry is loaded, and a protective rib 220 extending from the outer peripheral surface of the inlet to the opening 130 for preventing leakage of the foaming agent.

[00106] Unlike the illustrated drawing, the connecting rib 131 extending from the opening 130 to the inlet opening 211 of the inner housing may be formed in the housing 100.

[00107] That is, if the inner housing 210 and the housing 100 can be prevented from opening in the forward direction, then the inner housing 210 and the housing 100 can be formed into any shape and design.

[00108] In addition, the hot air supply device 400 may further include a safety rib 430 extending from the outer peripheral surface of the through portion 420 to the opening 130 to prevent leakage of the foaming agent.

[00109] The protective rib 220 and the safety rib 430 may prevent leakage of the foaming agent passing into the body 100 through the opening 130 by closing the opening 130.

[00110] In this case, the protective rib 220 located at the lower end of the inlet 221 and the safety rib 220 located at the upper end of the through section 420 may be configured to be tightly fixed to each other to protect the foaming agent between the inner casing 200 and the hot air supply device 400 from leakage.

[00111] In addition, the housing 410 for accommodating the hot air supply device 400 may be formed to be more elongated than the inner casing 200 in the rear direction so that the foaming agent ‘S’ can be protected from passing into the rear portion of the through portion 420.

[00112] That is, although the rear surface of the inner casing 200 is located at a distance from the rear surface of the housing 100, the housing 410 may be configured to extend until it is in contact with or connected to the rear surface of the housing 100.

[00113] Therefore, the front and rear length of the housing 410 may be greater than the front and rear length of the inner casing 200.

[00114] As a result, the discharge unit 460 can be removed from the housing 100 without colliding with the foaming agent.

[00115] In this case, the laundry treating device 10 of the present invention may comprise a base 500 located at a lower portion of the hot air supply device to form a lower surface of the body 100 or located in the body 100 to support the inner casing 200 and the hot air supply device 400.

[00116] The base 500 may be made of a vibration-absorbing material to prevent vibration from being transmitted to the outside of the laundry treating device 10.

[00117] The foaming agent S may be filled between the lower surfaces of the housing 100 to secure the base 500. Alternatively, the base 500 may be configured to be removable to the outside of the housing 100. In this case, the base 500 may serve as a discharge unit 460.

[00118] In this case, the inner casing 200 may be made of polypropylene (PP) resin, which is commonly used. The reason is that the polypropylene resin has excellent mobility and dimensional stability for easy molding and has excellent strength.

[00119] However, since the inner casing 200 is a high-temperature and humid environment due to the hot air or moisture supplied by the hot air supply device 400, it may be difficult to ensure the strength of the polypropylene resin. In addition, since the polypropylene resin has a drawback in that it does not have excellent adhesion to the foaming agent, it may be difficult to form the inner casing 200 from the polypropylene resin. The reason is that the inner casing 200 may move inside the body 100 or may detach from the body 100 if the foaming agent does not ensure adhesion.

[00120] Therefore, the laundry treating apparatus 10 of the present invention should use a material that can maintain adhesion and cohesion with the foaming agent even in a high-temperature and humid environment in the inner casing 200.

[00121] For this purpose, in the laundry treating apparatus 10 of the present invention, the inner casing 200 may be made of a styrene resin that can maintain adhesion with the foaming agent S.

[00122] Styrene resin is an aromatic hydrocarbon having a structure in which one hydrogen of a benzene ring is replaced by a vinyl group, and is one type of thermoplastic resin based on petrochemicals, and means a resin made of polystyrene, which is a polymer of a liquid styrene unit structure formed by the reaction of ethylene with benzene. A styrene resin is known that has excellent adhesion to a foaming agent and can maintain its original properties even in a high-temperature and humid environment because its boiling point is 145°C or higher.

[00123] Accordingly, the inner casing 200 is made of styrene resin and thus can maintain the strength at a certain level even in a high-temperature and humid environment and also maintain the adhesion with the foaming agent, and can be securely fixed to the body 100.

[00124] In detail, the inner casing 200 may be made of a copolymer of acrylonitrile, butadiene and styrene (ABS), which can maintain adhesion with the foaming agent and has excellent impact resistance to ensure strength.

[00125] ABS resin is a styrene resin made of three components of styrene, acrylonitrile and butadiene, and has an impact resistance greater than that of the basic styrene resin, which is easy to process and has a heat resistance more excellent than that of the ordinary styrene resin.

[00126] In detail, the ABS resin has a heat resistance superior to that of the polypropylene resin by not less than 16%, and has an impact resistance superior to that of the polypropylene resin by 5.6 times or more. Therefore, the ABS resin can maintain its original properties even in a high-temperature and humid environment such as the inner casing 200, and has excellent adhesion even with the foaming agent to maintain strength and rigidity in the middle of tight adhesion with the foaming agent and even in a state where it is tightly adhering to the foaming agent.

[00127] Therefore, the inner casing 200 can be made of ABS material and bonded to the foaming agent regardless of the liquid state and the solid state of the foaming agent, as a result of which the inner casing 200 can be completely fixed to the body 100.

[00128] In addition, since the ABS resin is excellent in rigidity, heat deformation resistance and the like, the ABS resin can be prevented from physical deformation and degradation even if it is constantly exposed to a high-temperature and humid environment.

[00129] In this case, the inner casing 200 is likely to be exposed to various secretions such as sweat and saliva secreted from the laundry and external particles.

[00130] Therefore, if the discharges and particles are absorbed into the inner casing 200, a problem may arise in that the cleanliness of the laundry treating device 10 cannot be ensured.

[00131] In addition, if the inner casing 200 chemically reacts with the discharge and particles separated from the laundry, a problem may arise in that the color of the inner casing 200 or the sanitation and stability of the inner casing cannot be ensured.

[00132] Therefore, it may be required that the inner casing 200 be made of a resin having color retention and strength that are more excellent than the color retention and strength of the ABS resin, and having excellent heat resistance, chemical resistance and thermal stability.

[00133] For this purpose, the laundry treating device 10 of the present invention can be manufactured such that the inner body 200 is made of ABS resin of styrene resin.

[00134] ABS resin is an acrylate styrene acrylonitrile copolymer (ASA), and it is known that weather resistance, chemical resistance and heat resistance are very excellent since it does not include an unstable double bond in a polymer such as ABS.

[00135] That is, even if the ASA resin is exposed to each or all of the organic material containing emissions, inorganic material containing particles, hot air and moisture, its physical and chemical properties cannot be changed.

[00136] Therefore, if the inner casing 200 is made of ASA resin, even if the inner casing 200 is exposed to hot air or moisture, the inner casing 200 can be prevented from chemically reacting with the fluid inside the accommodation area. As a result, the strength of the inner casing 200 can be ensured and the odor can be substantially prevented from being absorbed by the inner casing 200.

[00137] In this case, since the suspension unit 300 is located on the upper section of the inner casing 200, it is necessary to prevent the foaming agent from passing there.

[00138] For this purpose, the laundry treating device 10 of the present invention may further include a hollow portion 240 that forms a void area by preventing the foaming agent from passing thereto, so that the hanging unit 300 can be disposed between the upper surface 101 of the casing and the inner casing 200.

[00139] The hollow portion 240 may be formed by molding a molding article mounted on the upper surface of the body 100 and the upper surface of the inner casing 200 in a jig for fixing the body 100 and the inner casing 200 during the foaming process.

[00140] In addition, the hollow portion 240 may be formed by injecting a foaming agent into a separate casing inserted between the body 100 and the inner casing 200 and then removing the casing after a specific time.

[00141] In addition, the hollow portion 240 may be formed by a split rib or casing extending from the inner surface of the housing 100 to the inner casing 200 or extending from the inner casing 200 to the inner surface of the housing 100.

[00142] The hollow portion 240 can prevent the suspension unit 300 from interfering with the foaming agent even if the foaming agent is inserted into the housing 100, and can provide convenience in arranging or repairing the suspension unit 300.

[00143] The hollow portion 240 may be formed in the shape of a hexagon as shown, but may be formed to match the outer shape of the suspension assembly 300 or in another shape in which the suspension assembly 300 can be accommodated.

[00144] The hollow section 240 can be made in any shape and volume if the suspension unit can be made without filling it with a foaming agent.

[00145] For example, in the laundry treating apparatus 10 of the present invention, the hollow portion 240 may be formed to include a protective casing 241 connected to the upper surface of the inner casing 200 to protect the foaming agent from entering the inner casing.

[00146] The protective cover 241 may be located at a distance from the upper surface of the inner cover 200 to the upper surface 101 of the cover and thus is installed in the inner cover 200 and the upper surface 101 of the cover.

[00147] In addition, the protective casing 241 may be formed as a single unit with the inner casing 200.

[00148] The protective housing 241 may be formed in the shape of a hexagon as shown, but may be formed to match the outer shape of the suspension assembly 300 or in another shape that may provide a hollow portion 240.

[00149] The protective casing 241 can be made in any shape and volume if the suspension unit can be made without filling it with a foaming agent.

[00150] In this case, while the foaming agent is filled between the inner casing 200, the hot air supply device 400 and the housing 100, air corresponding to the volume of the filled foaming agent must be discharged to the outside of the housing 100. The reason is that a region where the foaming agent is not filled occurs inside the housing 100 if the air is not quickly discharged to the outside of the housing 100 during the foaming process.

[00151] For this purpose, a plurality of curved openings 700 through which air from the inside of the body 100 can be discharged may be formed in the body 100, the inner casing 200 and the hot air supply device 400.

[00152] The curved openings 700 may have a diameter through which only air is discharged, without discharging the liquid foaming agent to the outside, even if the foaming agent is in contact with the curved openings. That is, since the liquid foaming agent has a viscosity that is relatively high, if the curved opening 700 has a small diameter, the foaming agent cannot be discharged to the outside of the curved opening 700, even if the foaming agent passes into the curved openings 700 or is in contact with the curved opening 700. For example, the diameter of the curved opening 700 may be 0.5-1.5 mm. Therefore, air can be discharged only into the curved opening 700, and the foaming agent can be prevented from being discharged.

[00153] In this case, if air is released into the curved opening 700, a relative sound pressure is created, as a result of which the foaming agent can be directed to approach the curved opening 700. Therefore, the curved opening 700 can serve to direct the foaming agent to approach it and fill the foaming agent in it.

[00154] In this case, if the foaming agent is filled through the body 100, such as the rear surface of the body 100, the curved opening 700 may be formed in at least any of the protective rib 220 and the safety rib 430 to uniformly fill the foaming agent from the front of the inner casing and the front of the hot air supply device 400. The curved opening 700 may be formed in a plurality in the length direction of the protective rib 220 and the safety rib 430. Therefore, if the foaming agent is filled into the body 100, air from the body 100 is discharged into the curved opening 700 formed in the safety rib 430 and the protective rib 220, and the foaming agent can be supplied by reaching the rear surfaces of the safety rib 430 and the safety rib 220.

[00155] In other words, since the protective rib 220 is located on the outer peripheral surface of the inlet 211, and the safety rib 430 is located on the outer peripheral surface of the through portion 420, the foaming agent can be filled along the outer peripheral surface of the inner casing 210 and the outer peripheral surface of the housing 410 due to the curved opening 700 and can reach the safety rib 430 and the protective rib 220. As a result, the inner part of the housing 100 and the outer part of the inner housing 210 and the housing 410 can be completely filled with the foaming agent.

[00156] In this case, the inlet opening 401 for communication formed on the upper surface 412 of the housing body 410 and the opening 212 for communication on the lower surface of the inner housing 210 must communicate with the channel 230 for communication. The channel 230 for communication can be configured to connect with the inner housing 230 and the housing body 410 before the foaming agent is injected. In addition, the channel 230 for communication can serve to prevent the foaming agent from passing into the inlet opening 401 for communication and the opening 212 for communication.

[00157] In detail, the communication channel 230 may include a channel body 231 communicating the inner casing 200 with the hot air supply device 400, a channel placement portion 232 configured to extend from one end of the channel body 231 and located on a lower surface of the inner casing 200, and a channel insertion portion 233 extending from the other end of the channel body and inserted into the hot air supply device 400.

[00158] The duct body 231 may be formed in a shape corresponding to any of the heat pump 450, the communication opening 212, and the communication inlet 401, and may provide a region in which air moves by forming a cavity therein. The duct insertion portion 233 may be formed with the same diameter as the diameter of the duct body 231, or with a diameter slightly larger than the diameter of the duct body 231, and thus be forcibly installed or inserted into at least one of the communication opening 212 and the communication inlet 401. The duct placement portion 232 may be formed larger than the diameter of the duct body 231, and then located at the lower end of the inner body 210 or the upper end of the communication opening 212 to determine the position of the duct body 231.

[00159] Therefore, the channel insertion portion 233 can simultaneously pass and be inserted into the communication opening 212 and the communication inlet 401 until the channel placement portion 232 is positioned in the communication opening 212, as a result of which the channel insertion portion 233 can communicate with the heat pump 450. That is, the communication channel 230 can fix the inner casing 200 and the hot air supply device 400 by communicating the inner casing 200 and the hot air supply device 400 with each other before the foaming agent is injected into the inner casing 200 and the hot air supply device 400. The communication channel 230 can be formed in a plurality to correspond to the number of the communication openings 212 and the communication inlets 401.

[00160] In addition, the channel insertion portion 233 and the channel positioning portion 232 may be formed of a material having a soft material or elasticity, as a result of which the channel insertion portion 230 can be easily positioned in the communication inlet 401 and the communication opening 212.

[00161] Fig. 4 shows a structure for injecting a foaming agent into a laundry treatment device of the present invention.

[00162] As shown in Fig. 4(a) and 4(c), the housing 100 may include an injection hole 140 on the rear surface to allow injection of the foaming agent therein. At least one or more injection holes 140 may be formed on the rear surface of the housing to spray the foaming agent into the front portion of the housing.

[00163] The injection hole 140 may be formed in at least one of the side surface, the upper surface and the lower surface (if any) of the housing 100. However, since the rear surface of the housing 100 faces the inner casing 200 and the hot air supply device 400, the injection hole 140 is preferably located on the rear surface of the housing 100. This is necessary to ensure that the foaming agent is uniformly filled in the inner casing 200 and the hot air supply device 400 without concentrating in any area of the inner casing 200 and the hot air supply device 400.

[00164] In this case, if a plurality of injection holes 140 are configured to be provided on the rear surface of the housing 100, the foaming agent can be uniformly filled in the entire area of the housing 100. However, if a plurality of injection holes 140 are configured to be provided, the aesthetic perception may be deteriorated, and inconvenience may arise in that a plurality of separate elements are required to protect the injection holes 170.

[00165] Therefore, the injection holes 140 can be formed so as to adjoin each other at the central portion of the rear surface of the body 100. Therefore, the foaming agent S can be uniformly supplied to the upper and lower portions of the body 100, and finishing can be performed simply.

[00166] In this case, the laundry processing device 10 of the present invention may further comprise an intermediate retainer 170 for maintaining a distance between the inner casing 200 and the body 100. The intermediate retainer 170 may be formed as a rib located along the side of the body, or may be formed as a rod that is completely in contact with the rear surface of the body and the rear surface of the inner casing. The intermediate retainer 170 may be formed as a single unit with the body 100 or may be formed separately by inserting between the body 100 and the inner casing 200.

[00167] If the intermediate retainer 170 is disposed, the injection holes 140 may be formed by inserting the intermediate retainer 170. For example, the injection holes 140 may be formed symmetrically with respect to the intermediate retainer 170. If the position and distance of the inner casing 200 and the body 100 can be fixed by a jig and the like, the intermediate retainer 170 may be omitted.

[00168] In this case, the foaming agent S should be uniformly supplied between the sides of the inner casing 200 and the hot air supply device 400 and the side of the body 100, and between the inner casing 200 and the hot air supply device 400, as well as into the area between the rear surface 200 and the rear surface of the body 100.

[00169] As shown in Fig. 4(a), the upper surface of the inner casing 200, the lower surface of the housing 100, the region between the inner casing 200 and the hot air supply device 400, the side surfaces of the inner casing 200 and the hot air supply device and the side surface of the housing 100 are located further from the injection hole 140 than the region between the rear surface of the inner casing 200 and the rear surface of the housing 100.

[00170] Therefore, if the foaming agent S is injected from the foaming agent injection hole 140, it may be more difficult to fill the foaming agent S on the upper surface of the casing 200, on the lower surface of the body 100, the area between the inner casing 200 and the hot air supply device 400, the side surfaces of the inner casing 200 and the hot air supply device and the side surface of the body 100 than the area between the rear surface of the inner casing 200 and the rear surface of the body 100.

[00171] As shown in Fig. 4(b), the laundry treating device 10 of the present invention may include a plurality of curved holes 700 that guide the movement of the foaming agent when air from the body is discharged toward the side of the body 100, so that the foaming agent S can be uniformly filled in the entire area. In this way, the plurality of curved holes 700 can guide the foaming agent S to pass deeper away from the injection port 140 when air is discharged from the body 100 toward the outside.

[00172] For this purpose, the plurality of curved openings 700 may be formed at a closer distance toward the front (opening) of the body 100 or may be formed more at the front than at the rear to guide the foaming agent S to reach the side and front side of the body 100.

[00173] In this case, more of the foaming agent S must pass between the upper surface of the housing 100 and the upper surface of the inner casing 200 and between the inner casing 200 and the hot air supply device 400 and must be filled more specifically. Therefore, the plurality of curved holes 700 are preferably formed in any of a portion corresponding to the distance between the inner casing 200 and the hot air supply device 400 and a portion corresponding to the distance between the inner casing 200 and the upper surface of the housing 100.

[00174] In this case, even if the foaming agent S is injected from the rear surface of the housing 100, the foaming agent S may be injected into the housing 100 in a position in which the rear surface of the housing 100 faces the upper portion (see Fig. 5). Therefore, even if the foaming agent S is injected from the rear surface of the housing 100 and filled from the front of the housing 100 or the opening 101, it may be difficult to easily secure the foaming agent S to the rear surface of the housing 100.

[00175] As shown in Fig. 4(c), the laundry treating device 10 of the present invention may further comprise a plurality of curved openings 700 to ensure that the foaming agent S can be easily fixed to the rear surface of the casing 100. Therefore, if the foaming agent S is filled into the casing 100 and then heated or inflated by curing, air from the rear surface of the casing 100 can be discharged through the curved openings 700, as a result of which the foaming agent S can be filled to the rear surface of the casing 100.

[00176] In this case, the curved opening 700 can be formed between the upper surface of the body 100 and the upper surface of the inner casing 200 and in a position corresponding to the inner casing 200 and the hot air supply device 400. Therefore, the curved openings 700 can guide the foaming agent S to reach the rear surface of the body 100, while the foaming agent passing into the above-mentioned region is filled.

[00177] In addition, the curved openings 700 may be formed at both ends of the rear surface of the body. Therefore, the foaming agent S may be filled in the region where the rear surface of the body 100 and the side surface of the body 100 adjoin each other.

[00178] In this case, the foaming agent S cannot easily pass to the edge of the region where the injection holes 140 face each other on the rear surface of the body 100. Therefore, the curved holes 700 may be further formed in such a way that the foaming agent S can pass into the above-mentioned region.

[00179] In this case, the discharge opening 190 for removing the discharge unit 460 may be further formed on the rear surface of the housing 100. Since the housing 410 is arranged such that its rear side must be in contact with the discharge opening 190, the foaming agent S can be prevented from passing into the discharge opening 190.

[00180] In addition, as described above, the foaming agent S can be prevented from filling in the hollow portion 240.

[00181] Fig. 5 shows the process of filling the foaming agent S in the laundry treating device 10 of the present invention.

[00182] Fig. 5(a), 5(c), 5(e) and (5g) are sectional views of the laundry treating device 10 of the present invention, and Fig. 5(b), 5(d), 5(f) and (5h) are views of the rear surface of the laundry treating device 10 of the present invention.

[00183] As shown in Fig. 5(a) and 5(b), the inner casing 200, the hot air supply device 400, and the base 500 may be fixed by insertion into the body 100 in a state where they are connected to each other. The inner casing 200 and the hot air supply device 400 may be fixed and connected to each other using a separate conductor.

[00184] After this, the foaming agent S can pass to the rear surface of the housing 100 through the injection holes 140. The foaming agent S can partially move to the lower portion along the side surface of the inner casing 200 when moving along the rear surface of the inner casing 200.

[00185] As shown in Fig. 5(c) and 5(b), when the foaming agent S passes through the injection holes 140, air of a volume corresponding to the volume of the foaming agent S is discharged through the curved holes 700. Therefore, the foaming agent S can be inserted into the empty area formed by the body 100, the inner casing 200 and the hot air supply device 400 more actively.

[00186] As shown, if the curved holes 700 are formed in the protective rib 200 located in the inner casing or in the safety rib 430 located in the hot air supply device, the foaming agent S can more actively pass to the protective rib 220 and the safety rib 430.

[00187] Even if the curved holes 700 are not formed in the protective rib 220 or the safety rib 430, the foaming agent S can pass toward the protective rib 220 and the safety rib 430 under the action of the load of its own mass.

[00188] As shown in Fig. 5(e) and 5(f), if the foaming agent S reaches the protective rib 220 and the safety rib 430, the foaming agent S can fill another region when filling on the side surface or the upper portion (rear surface of the casing) without moving more to the lower portion.

[00189] If the curved openings 700 are formed on the rear surface of the body 100, air can be discharged into the curved openings 700, and the foaming agent S can move toward the rear surface of the body 100.

[00190] In this case, the foaming agent S can be additionally supplied for filling when air is displaced to the curved openings 700 on the rear surface of the housing 100 or can be filled on the rear surface of the housing 100 when swelling by heating or natural cooling in a position in which it stops being additionally supplied.

[00191] That is, when air is intensively discharged into the curved openings 700 formed on the rear surface of the body 100, the foaming agent S is filled until it reaches the region where the filling is not completed, as a result of which the empty region can be filled with the foaming agent.

[00192] At the same time, the foaming agent S can pass toward the side surface of the housing 410 for accommodating and the base 500, as a result of which the foaming agent S can pass into the empty area formed by the housing 410 for accommodating or the base 500 and the housing 100.

[00193] As shown in Fig. 5(g) and 5(h), if the foaming agent S is heated or swells as a result of curing, or if the foaming agent S is further supplied, the foaming agent S may pass into the region where filling is not completed on the rear surface of the body 100.

[00194] Generally, since the foaming agent S can be slowly supplied to the region where the corners of the body 100 correspond to each other or to the region where the injection holes 140 face each other, the foaming agent S can be finally filled in this region.

[00195] In this case, if the curved holes 700 are formed in the region where the corners of the body 100 correspond to each other, or in the region where the injection holes 140 face each other, the air from the body 100 is finally discharged into the curved holes 700, as a result of which the foaming agent S can be completely filled in the body 100.

[00196] Therefore, the foaming agent S can be completely filled in the region formed by the inside of the body 100, the outside of the inner casing 200 and the outside of the hot air supply device 400. In addition, if the foaming agent S is cured, the inner casing 200, the hot air supply device 400 and the base 500 can be stably fixed to the body 100.

[00197] However, as described above, since the rear surface of the housing 410 for accommodating is in contact with or connected to the rear surface of the housing 100, the inlet and filling of the foaming agent S can be excluded from the region corresponding to the through portion 420. Therefore, the discharge unit 460 can be removed through the discharge opening 190 formed on the rear surface of the housing.

[00198] In this case, the foaming agent S can be prevented from filling a specific region between the upper surface of the body 100 and the upper surface of the inner casing 200, thereby forming a hollow portion 240.

[00199] The hollow section 240 may be formed with a protective casing 241 extending from the inner surface of the housing 100 to the inner casing 200 or extending from the inner casing 200 to the inner surface of the housing 100.

[00200] In contrast to this case, the hollow section 240 may be formed by providing a jig (not shown) for fixing the housing 100 and the inner casing 200 during the foaming process, which partially passes through the upper surface of the inner casing 200 and the housing 100.

[00201] In addition, the hollow section 240 can be formed as a jig containing a molding that can be inserted onto the upper surface of the body 100 and the upper surface of the inner casing 200.

[00202] In addition, the hollow section 240 may be formed as a separate housing, which is inserted between the housing 100 and the inner casing 200, the foaming agent is injected into the housing, the upper surface of the housing 100 is opened after a specific time, and then the housing is removed.

[00203] As a result, the laundry processing apparatus of the present invention can simplify the assembly process by eliminating the frame using the foaming agent S, and ensure durability and insulation properties.

[00204] Fig. 6 shows a sectional view of a laundry processing device in which the process of Fig. 5 is completed.

[00205] As shown in Fig. 6, the inside of the body 100 and the area between the inner casing 200 and the hot air supply device 400 may be filled with a foaming agent S.

[00206] Since the foaming agent S is filled in the region where the frame is located, the frame can be eliminated, as a result of which the process of assembling the frame and the process of connecting the frame, the body and the inner body can be eliminated.

[00207] Moreover, unlike a refrigerator, the laundry processing device of the present invention does not require ideal insulation and does not require a large thickness L to ensure the maximum volume of the internal area for accommodation.

[00208] In addition, the laundry processing device of the present invention may have a height H greater than the height of the refrigerator to accommodate the laundry in a non-folding accommodation area.

[00209] In this case, if the inside of the body 100 is filled only with the foaming agent S, the foaming agent S is relatively thin and long, as a result of which the durability may be deteriorated. In addition, the foaming agent S, thinly filled with a long length, may have a variable shape due to the bending force when the foaming agent is cured.

[00210] In order to increase or maintain the durability and rigidity of the foaming agent S, the laundry treating device of the present invention can completely fill the foaming agent S in a horizontal region between the inner casing and the hot air supply device, and in a vertical region between the side surface of the body and the side surface of the inner casing and the hot air supply device.

[00211] In this way, since the foaming agent S is filled entirely in the width direction inside the laundry treating device and also in the height direction of the laundry treating device, the stability of the foaming agent S can be ensured structurally. Therefore, the rigidity and strength of the laundry treating device and the foaming agent S can be increased.

[00212] Therefore, even if an external environmental impact is transmitted to the housing 100 or a strong vibration is generated inside the housing 100, since the foaming agent S is firmly fixed in an ‘H’ shape, the foaming agent S can be prevented from being damaged or deformed.

[00213] In this case, since the foaming agent S serves to fix the inner casing 200 and the hot air supply device 400 and maintain the shape and rigidity of the laundry treatment device 10, the foaming agent S can be sufficiently filled only on the side surfaces (including the rear surface) of the inner casing 200 and the hot air supply device 400.

[00214] In addition, since the processing unit 300 may be located on the upper surface of the inner casing 200, the hollow portion 240 must be formed on the inner casing 200 as described above.

[00215] In addition, the base 500 or the discharge unit 460 can be removed to the outside if necessary, and if the foaming agent S is filled in the lower portion of the housing 100, the installation according to the level of the housing 100 may not be maintained depending on the solidified form of the foaming agent. Therefore, it may be more effective that the foaming agent S is excluded in the lower portion of the housing 100.

[00216] In addition, if the foaming agent S condenses during its curing process, a bending force F is generated at both ends of the foaming agent, which may result in a problem that the shapes of the inner casing 200 or the base 500 change.

[00217] Therefore, in the laundry treating device 10 of the present invention, the foaming agent S cannot enter into a specific region of the upper portion of the inner casing 200 and the lower portion of the base 500.

[00218] As a result, the foaming agent S can be used in the structure H in which a specific area of the upper portion and the lower portion in the laundry treating device is open, as a result of which the placement of the treating unit 300 or the removal of the heat pump 465 can be easily performed.

[00219] Fig. 7 shows another embodiment of the laundry treating device 10 of the present invention, in which the foaming agent S is prevented from passing to the upper portion of the inner casing 200 and the lower portion of the base 500.

[00220] In the same manner as in the previous embodiment, the inner casing 200 may include a hollow portion 240 that provides an area in which the suspension unit 300 is located on the upper surface and prevents the foaming agent S from contacting the suspension unit 300.

[00221] However, the hollow section 240 of the laundry processing device shown in Fig. 7 may be formed as a protective rib 242 located between the upper corner of the inner casing 200 and the upper surface of the body.

[00222] That is, the protective rib 242 may be configured to contact the upper corner of the inner casing 200 and the upper surface of the housing 100 located on the upper portion of the upper corner. In addition, the protective rib 242 may be configured to extend from the upper corner of the inner casing 200 to contact the upper surface of the housing 100.

[00223] Therefore, the foaming agent S passing from the injection holes 140 can be substantially prevented from passing to the upper surface of the inner casing 200 due to the protective rib 242.

[00224] In addition, the base 500 of the laundry treating device 10 may further include a leakage preventing block 530 further extending from the support portion of the housing 410 to be placed toward the side surface of the housing, to prevent leakage of the foaming agent passing into the housing to the lower portion of the housing 100.

[00225] In other words, the leakage preventing block 530 may be in contact with the inner peripheral surface of the lower surface of the body 100 to prevent the foaming agent S from leaking into the body 100. As a result, the foaming agent S may be substantially prevented from passing to the lower surface of the base 500. The body 100 may not include a lower surface due to the base 500.

[00226] In addition, the base 500 may extend in contact with the lower end of the housing 100 and be configured to replace the lower surface of the housing 100. That is, the housing 100 may be configured to be located on the leakage preventing block 530 of the base 400.

[00227] Fig. 8 shows a structure in which the foaming agent S is filled in the laundry treatment device of Fig. 7.

[00228] Fig. 8(a) is a side sectional view of the laundry treating device 10, Fig. 8(b) is a front view of the laundry treating device 10, and Fig. 8(c) is a rear view of the laundry treating device 10.

[00229] As shown in Fig. 8(a) and 8(b), the foaming agent S may be configured to be filled in a region other than the upper portion of the inner casing 200 and the lower portion of the base 500. In this way, the region in which the processing unit 300 can be located can be provided, and the upper portion of the inner casing 200 or the lower portion of the base can be prevented from bending inward when the foaming agent S is cured.

[00230] Therefore, as shown in Fig. 8(b), the foaming agent of another embodiment of the laundry treating device 10 according to the present invention can be arranged in an ‘H’ shape to fill the body. Therefore, the heat in the inner case 200 can be prevented from leaking to the side surface or the rear surface of the body 100 and can maintain the main rigidity, and at the same time, can prevent deformation of the shapes of the upper portion and the lower portion of the body 100 or prevent the occurrence of unnecessary compressive force.

[00231] In addition, as shown in Fig. 8(c), the foaming agent S can be excluded from the region from which the discharge unit 460 is removed due to the base 500 and the through portion 420 of the housing 410 for receiving.

[00232] Fig. 9 shows another embodiment of a device 10 for treating laundry.

[00233] The hollow section 240 may be formed as a protective rib 243 extending from the upper corner of the inner casing 200 to the side of the housing 100 to protect the foaming agent S from passing onto the upper surface of the inner casing.

[00234] In detail, the protective rib 243 may be configured to extend from a corner, except for the protective rib 220, of each corner of the upper surface of the inner casing 200 to be located at a distance from the inner casing 200 and thus configured to contact the inner portion of the housing 100.

[00235] Therefore, the protective rib 243 can substantially protect the foaming agent S coming out of the injection holes 140 from contacting the upper surface of the inner casing 200 and can provide a wider area at the upper portion of the inner casing 200 to facilitate the placement of the suspension unit 300.

[00236] In addition, the protective rib 243 can be formed to be convex upward in contrast to the protective rib 242, thus accommodating a part of the foaming agent S. The adhesion of the protective rib 243 and the foaming agent S can be strengthened, as a result of which the foaming agent S can be directed to be rigidly connected and fixed with the inner casing 200.

[00237] In this case, the laundry treating device of the present invention may further comprise a plurality of curved openings 700 guiding the foam generator to move toward the protective rib 243 and to contact the protective rib by passing through the protective rib 243.

[00238] That is, since the protective rib 243 extends from the upper surface of the inner casing 200 to the outer side, the lower end of the protective rib 243 is configured to contact the foaming agent S. Therefore, curved holes 700 can be formed on the protective rib 243 to guide the foaming agent S to easily pass to the protective rib 243 by discharging air from the casing 100 to the protective rib 243.

[00239] The curved openings 700 can be formed in a plurality in the direction of the length of the protective rib 243.

[00240] Fig. 10 shows that the foaming agent S is filled in the laundry treating device 10 comprising the protective rib 243.

[00241] As shown in Fig. 10(a), it should be noted that the foaming agent S passes onto the protective guide rib 243 due to the curved holes 700 formed in the protective rib 243. In addition, the empty area can be further increased on the upper surface of the inner casing 200, as a result of which the suspension unit 300 can be easily installed and repaired.

[00242] As shown in Fig. 10(b) and 10(c), the foaming agent S may be disposed inside the H-shaped body by the protective rib 243 and the base 500. In addition, the protective rib 243 may be more rigidly connected to the foaming agent S by disposing the upper end of the foaming agent S.

[00243] Furthermore, even if a compressive force of the foaming agent S is generated relative to the inner casing 200, the protective rib 243 can maintain the internal stress by dispersing the above-mentioned force over the area. As a result, the durability and stability of the arrangement of the laundry treating device 10 can be further increased.

[00244] In this case, in all embodiments of the laundry treatment device of the present invention, if the thickness of the foaming agent S is large, it may be advantageous for ensuring rigidity and maintaining the shape, however, a problem may arise that the inner region becomes narrow. In addition, if the thickness of the foaming agent S is small, the area for accommodating the hot air supply device 400 and the inner casing 200 can be expanded, however, a problem may arise that the rigidity weakens.

[00245] In addition, the laundry treating device 10 of the present invention can be formed relatively higher than a household appliance such as a refrigerator due to the presence of the hot air supply device 400 located at the lower portion, and it is necessary to determine the range of the thickness of the foaming agent S that the laundry treating device can support.

[00246] As an experimental result, it was noted that the ratio of the height of the laundry treating device 10 of the present invention and the thickness of the foaming agent S should be greater than 60 and less than 95 to ensure the minimum rigidity.

[00247] For example, if the height of the laundry treatment device 10 is 1870 mm, the thickness of the foaming agent S is preferably 20-30 mm.

[00248] In detail, if the ratio of the height of the laundry treating device 10 and the thickness of the foaming agent S is less than 60, since this means that the foaming agent S is too thick, the minimum area in which the heat pump 450 is located is limited, as a result of which the laundry treating device 10 cannot be manufactured.

[00249] In addition, if the ratio of the height of the laundry treating device 10 and the thickness of the foaming agent S is greater than 93, since this means that the foaming agent S is too thin, the minimum rigidity is not maintained, resulting in the foaming agent S being sprayed under the action of the load of the dead weight of the laundry treating device 10.

[00250] Therefore, if the ratio of the height of the laundry treating device 10 and the thickness of the foaming agent S is greater than 61 and less than 93, this may mean a minimum essential range that allows the laundry treating device 10 of the present invention to be normally manufactured and operated.

[00251] In this case, the thickness of the foaming agent S may correspond to the distance between the side surface of the inner casing 200 and the side surface of the body 100 or the distance between the rear surface of the inner casing 200 and the rear surface of the body 100.

[00252] In addition, the thickness of the foaming agent S may correspond to the distance between the side surface of the hot air supply device 400 and the side surface of the body 100.

[00253] Accordingly, the inner casing 200 and the hot air supply device 400 may be located at a distance from the housing 100 at a maximum distance corresponding to 1/90-1/60 of the total height of the housing 100.

[00254] Fig. 11 shows that the body 100 of the laundry treating device 10 of the present invention is bent under the action of an external force.

[00255] In the laundry treating device 10 of the present invention, since the height of the accommodating region is large for accommodating the laundry in the inner case 200 without folding the laundry, and the hot air supply device 400 is also located at the lower portion of the inner case 200, the height of the body 100 is made higher than the height of other household appliances. Therefore, the rear surface and the side surface of the body 100 may have a rigidity or strength that is relatively unstable, and may easily bend under the action of an external force.

[00256] In this case, the foaming agent S is filled in the empty region of the housing 100 while its volume expands in the middle of the heating process or the curing process if the foaming agent is completely injected into the housing 100. Therefore, even if the foaming agent S is not injected into the entire region inside the housing 100, the foaming agent S can be filled in the entire region inside the housing 100 while expanding in the middle of the curing process.

[00257] However, if the strength or rigidity of the body 100 is insufficient in the middle of filling the foaming agent S, which expands, in the body 100, the body 100 may be deformed by the action of the expansion force of the foaming agent S.

[00258] As shown in Fig. 11, when the foaming agent S completely enters into the inside of the body 100 and expands during the curing process, and then fills in the empty area, the body 100 can be inflated by the expansion force of the foaming agent S.

[00259] In particular, since the rear surface or the side surface of the body 100 must be relatively longer than the upper surface, it may be more strongly swollen due to unstable rigidity.

[00260] If the body 100 is swollen, problems arise in that the aesthetic perception is deteriorated, the area occupied by the laundry treating device 10 is excessively enlarged, and the foaming agent S does not reach a predetermined area.

[00261] Therefore, the strength or rigidity required for the body 100 can be increased in the case of the laundry treating apparatus 10 of the present invention in which the frame is replaced by the foaming agent S.

[00262] Fig. 12 shows an embodiment in which the strength or rigidity of the body 100 can be increased.

[00263] As shown in Fig. 12, the laundry treating device 10 of the present invention may further include a deformation preventing block 160 disposed on or connected to the inner peripheral surface of the casing 100 to secure the inner casing 200 to the hot air supply device 400 and maintain the shape of the casing 100 even if the foaming agent filling the empty area is expanded.

[00264] The deformation preventing block 160 may include a widthwise connecting block 161 connected to both sides 120 of the housing 100 in the width direction of the rear surface 110 to prevent bending of the housing 100.

[00265] The connecting block 161 in width may be formed in the shape of "U" or "C" and is completely connected to the inner peripheral surface of the body 100 in the width direction. The connecting block 161 in width may be formed in a rectangular cross-section to ensure maximum contact area with the body 100 and maintain rigidity.

[00266] The connection block 161 in width may include a first connection block 1611 connected to one side 120 of the housing, a second connection block 1612 extending from one end of the first connection block 1611 and connected to the rear surface 110 of the housing, and a third connection block 1613 connected to the other side 120 of the housing at one end of the second connection block 1612.

[00267] The first connecting block 1611, the second connecting block 1612 and the third connecting block 1613 may be formed in the form of a rod with a length corresponding to each side of the body 100.

[00268] The first connection block 1611, the second connection block 1612 and the third connection block 1613 may be connected to each other by welding on the inner surface of the body 100, or may be connected by a connecting element such as a separate bolt or nut, or may be connected by means of a forced installation and a foaming agent S.

[00269] In this case, the first connecting block 1611, the second connecting block 1612 and the third connecting block 1613 may be formed with a thickness that is not in contact with the inner casing 200, in order to prevent the foaming agent S injected into the body 100 from moving.

[00270] In addition, the connecting block 161 in width may further include a plurality of guide holes 1614 for moving the foaming agent inside the body 100, even if the foaming agent S is in contact with the inner casing. That is, the guide holes 1614 may be formed in a plurality in the length direction of the first connecting block 1611, the second connecting block 1612 and the third connecting block 1613, and may be formed with a diameter larger than the diameter of the curved hole 700, so that the foaming agent S can enter them and move.

[00271] Since the guide holes 1614 are configured without the possibility of limiting the movement of the foaming agent S, the guide holes 1614 are preferably configured to pass through the first connecting block 1611, the second connecting block 1612 and the third connecting block 1613 in the direction of the height of the body 100.

[00272] In this case, if the foaming agent S passes into the guide holes 1614, the adhesion between the foaming agent S and the body 100 can be further improved to prevent the body 100 from bending arbitrarily.

[00273] In this way, the connecting block 161 can be completely connected in width to the inner peripheral surface of the housing 100 to support the housing 100, as a result of which any of the rear surface 110 and the side surface 120 of the housing 100 can be prevented from arbitrarily expanding or bending.

[00274] Since the portion of the body 100 which corresponds to the center based on the height direction is the most unstable, the connecting block 161 in width may be configured to be connected to the central portion based on the height direction of the body 100. However, the connecting block 161 in width may be configured in a plurality such that the connecting blocks 161 may be arranged at a distance from each other in the height direction of the body 100, if necessary.

[00275] In this case, the injection holes 140 may be formed at a distance from the connection block 161 in width. Therefore, the foaming agent S can be injected without interference due to the connection block 161 in width. If a plurality of connection blocks 161 are arranged in width, the injection holes 140 may be arranged between the corresponding connection blocks 161 in width.

[00276] Fig. 13 shows another embodiment of a deformation-preventing block that can increase the strength or rigidity of the body 100.

[00277] As shown in Fig. 13, the deformation preventing block of the present invention may include concave and convex portions 163 recessed or protruding in the height direction of the body 100.

[00278] The concave and convex portions 163 may be manufactured in such a manner that they form a stereoscopic effect on the surface of the body 100 by pressing the body 100 after manufacturing the body 100.

[00279] If the concave and convex portions 163 are formed recessed from one surface of the body 100, the concave and convex portions 163 are preferably formed with a depth that can prevent the foaming agent S from contacting the inner casing 200 without disturbing the movement of the foaming agent S. In detail, since the concave and convex portions 163 are formed with the possibility of increasing the rigidity of the body 100, the concave and convex portions 163 can be formed with a depth or height of 2-5 mm.

[00280] In addition, the concave and convex portions 163 can prevent the body 100, located longitudinally, from bending in the height direction.

[00281] Since the height is greater than the width, at least one or more concave and convex portions 163 may be formed on the side surface 120 of the housing and the rear surface 110 of the housing. However, in order to increase rigidity, the concave and convex portions 163 are preferably formed on the side surface 120 and the rear surface 110 of the housing.

[00282] In this case, the concave and convex portions 163 protrude or are recessed, as a result of which the foaming agent S cannot easily be in contact with the inner casing when the foaming agent S passes into it. To avoid this, the concave and convex portions 163 may comprise a plurality of curved openings 700 through which air is released from the housing 100.

[00283] In addition, the deformation preventing block 160 may include a height connecting block 162 connected in the height direction of the housing 100 to prevent bending of the housing.

[00284] The height connecting block 162 may be connected to the inner surface of the housing 100 in the height direction to increase the rigidity of the housing 100, thereby preventing the housing 100 from bending outward or inward.

[00285] One or more connecting blocks 162 in height can be made by welding on the side surface 120 or the rear surface 110 of the housing 100 or can be connected by a separate connecting element. In addition, the connecting blocks 162 in height can be located at a distance from each other on the side surface 120 and the rear surface 110 of the housing 100 or can be connected to the side surface 120 and the rear surface 110 of the housing one after the other.

[00286] That is, there is no limitation in the number of connecting blocks 162 in height and the position of the connecting blocks 162 in height, if the shape of the body 100 can be maintained.

[00287] In this case, as shown, the connecting blocks 162 in height and the concave and convex portions 163 can be arranged together. That is, the connecting blocks 162 in height can be arranged between the concave and convex portions 163 to prevent the shape of the body 100 from being deformed.

[00288] However, if one connecting block 162 in height and one concave and convex portion can be configured to sufficiently prevent bending of the housing 100, then the housing 100 can be configured with any of the connecting block 162 in height and the concave and convex portion 163.

[00289] In this case, although Fig. 13 shows that the connecting blocks 162 in height, formed in different shapes, are connected to the body 100, this is intended only for description, and the connecting blocks 162 in height can be connected in one single shape.

[00290] The connecting blocks 162 in height may include a contact rib 1621 contacting in the height direction of the rear surface 110 or the side surface 120 of the housing, and a protruding rib 1622 increasing the rigidity of the contact rib 1621.

[00291] The protruding rib 1622 may be formed as an integral part with the contact rib 1621 to prevent bending of the contact rib 1621 and may enhance adhesion to the foaming agent S by increasing the contact area with the foaming agent S.

[00292] As a result, the connecting blocks 162 in height can prevent the bending of the body 100 and maintain adhesion to the foaming agent S.

[00293] The connecting blocks 162 in height may include a contact channel 1623 contacting in the height direction of the rear surface 110 or the side surface 120 of the housing, and a reinforcing hole 1624 formed inside the contact channel 1623.

[00294] The contact channel 1623 can be formed in a rectangular cross-section to provide an area that is in contact with the housing 100 and can maintain its rigidity to prevent bending of the housing 100. A reinforcing hole 1624 can be formed inside the contact channel 1623 to reduce the weight of the contact channel 1623 and increase the durability of the contact channel.

[00295] In addition, the connecting blocks 162 in height may include a contact tube 1625 contacting in the height direction of the rear surface 110 or the side surface 120 of the housing, and a hollow hole 1626 formed inside the contact tube. The contact tube 1625 is grounded with the housing 100 by a wire and, thus, can minimize the area connected to the housing 100.

[00296] As a result, even if the process of connecting the contact tube 1625 to the body 100 by welding is simplified, the body 100 can be sufficiently prevented from bending.

[00297] In addition, the connecting blocks 162 along the height may include a contact area 1626 contacting in the height direction of the rear surface 110 or the side surface 120 of the housing, and a guide rib 1627 extending from both ends of the contact area 1626 to the inner casing and connected to the foaming agent.

[00298] The contact area 1626 may sufficiently provide an area in contact with the housing 100 to prevent the housing 100 from bending. In addition, the guide rib 1627 may include a groove 1628 for receiving, which may be connected to the foaming agent S to increase the contact force with the foaming agent S and may prevent the contact area 1626 from bending, thus certainly preventing the housing 100 from bending.

[00299] As a result, in the laundry treating device 10 of the present invention, even if the foamer S generates an expansion force at the position where it enters the housing 100, the shape of the housing 100 can be maintained. Therefore, the foamer S can be completely filled in the empty region of the housing.

[00300] In this case, although the above-mentioned deformation preventing block 160 is located inside the housing 100, as shown, the deformation preventing block 160 can be connected to the outside of the housing 100 to completely protect the housing 100 from external swelling.

[00301] Fig. 14 shows an embodiment in which the adhesion of the housing 100 and the inner casing 200 is strengthened.

[00302] If the foaming agent S is expanded, the inner casing 200 and the protective rib 220 may be located at a distance from the body 100, as a result of which the foaming agent S may flow out onto the outer peripheral surface of the protective rib 220.

[00303] Therefore, in any case, it is necessary to maintain the connection between the protective rib 220 and the housing 100.

[00304] For this task, the body 100 may further include a connecting rib 131 on the inner peripheral surface, which should extend to the protective rib 220 or be in contact with it. The connecting rib 131 may be configured to extend from the opening 130 to the inner part.

[00305] The connecting rib 131 may be configured to contact the protective rib 220 at a specific location and is secured to the protective rib 220 if the foaming agent S passes there.

[00306] In addition, the laundry treating device 10 of the present invention may further comprise a connecting unit 800 suspended in the connecting rib 131 for accommodating the free end of the protective rib 220 and connected to the protective rib 220.

[00307] The connecting unit 800 may include a connecting ring820 having an insertion surface on one surface on which the protective rib 220 can be disposed, and a pressure generating member 810 that can generate pressure on the connecting ring820.

[00308] Therefore, if the connecting portion 800 is disposed on the rear surface of the connecting rib 131, and the protective rib 220 is disposed in the connecting portion 800 and connected thereto, the foaming agent S can pass into the connecting portion 800 to create pressure on the connecting ring 820 and the pressure creating member 810, thereby rigidly creating pressure on the protective rib 220.

[00309] In this case, the housing 100 may include a recessed groove on the side that is in contact with the outer peripheral surface of the connecting unit 800.

[00310] Therefore, even if the protective rib 220 and the body 100 are not connected to each other by a separate connecting member, the protective rib 220 and the body 100 can be fixedly connected to each other by the foaming agent S via the connecting unit 800. Even if the foaming agent S expands to generate a force for pushing the body 100 outward, the protective rib 220 and the body 100 can be prevented from being located at a distance from each other.

[00311] Fig. 15 shows a case where the inner casing 200 and the foaming agent S can be located at a distance from each other without sticking to each other.

[00312] Even if the foaming agent S is inserted into the inner casing 200, the adhesion between the foaming agent S and the inner casing 200 may become weak. Therefore, when the foaming agent S is inserted, the foaming agent S may be adhered to the inner casing 200, and then located at a distance from the inner casing 200 when the foaming agent S is cured and compressed. Therefore, a hollow hole may be formed between the inner casing 200 and the foaming agent S, as a result of which the durability of the inner casing 200 may be significantly reduced. In addition, a problem may arise that heat from the inner casing 200 may be discharged to a region located at a distance from the foaming agent S, to reduce the thermal efficiency.

[00313] Fig. 16 shows an embodiment of the present invention that can continuously provide adhesion between the inner casing 200 and the foaming agent S.

[00314] The laundry treating device 10 of the present invention may comprise a gripping portion 250 configured to protrude or recess from the inner housing 210 to the body and connected to a foaming agent filled in the region between the body and the inner housing 210.

[00315] The gripping portion 250 may be formed as a single unit with the inner housing 210 or may be formed to be connected to the inner housing 210. The gripping portion 250 may include a separate region that accommodates the foaming agent S or is connected to the foaming agent S to maintain a connection with the foaming agent S, as a result of which the foaming agent S and the inner housing 210 can be prevented from being separated from each other.

[00316] The gripping portion 250 may be formed from a material different from the material of the inner body 210, and may be formed from a material having excellent adhesion to the foaming agent S. In addition, even if the gripping portion 250 is formed from the same material as the material of the inner body 210, its shape may grip the foaming agent S, thereby maintaining the connection with the foaming agent S.

[00317] Fig. 16(a) shows various shapes and designs of the gripping portion 250, and Fig. 16(b) shows another shape and design of the gripping portion 250.

[00318] That is, the gripping portion 250 may be formed in any of the structures shown in Fig. 16(a) and 16(b), and one gripping portion 250 or a plurality of gripping portions 250 may be formed.

[00319] As shown in Fig. 16(a), the gripping portion 250 may include a gripping housing 251 protruding from the inner housing 210 toward the housing to provide an area in which the foaming agent S is accommodated.

[00320] The gripping housing 251 may be located in the inner housing 210 without being in contact with the housing 100, thus not disturbing the movement of the foaming agent S.

[00321] The gripping housing 251 may include a housing body 251a connected to the inner housing 210 or extending to the inner housing 210, having the above-mentioned region, and a housing opening 251b formed on one surface of the housing body 251a to allow the foaming agent to pass into the above-mentioned region.

[00322] The housing body 251a may be formed by protecting other portions except for the housing opening 251b.

[00323] If the liquid foaming agent S passes into the gripping body 251, the liquid foaming agent may be solidified as a single unit with the foaming agent located outside the gripping housing 251.

[00324] Therefore, other surfaces, except for the opening 251b of the gripping housing 251, may be in contact with the foaming agent S and connected with the foaming agent S, and thereby, may grip the foaming agent S.

[00325] In detail, the gripping hole 251b may be formed parallel to one surface of the inner case 210. Therefore, since the gripping housing 241 is configured to be embedded in the foaming agent S, the foaming agent S cannot be separated from the gripping housing 241. As a result, the connection between the foaming agent S and the inner case 200 can be maintained.

[00326] In this case, the gripping portion 250 may include a gripping bracket 253 protruding from the inner body 210 to the body 100 and connected to the foaming agent S.

[00327] The gripping bracket 253 may include a protruding rib 253a protruding from the inner body 210 toward the body, a first gripping rib 253b protruding at an angle from the protruding rib 253a, and a second gripping rib 253c protruding from the protruding rib 253a in a direction different from the first gripping rib.

[00328] The first gripping rib 253b and the second gripping rib 253c may extend from the free end of the first gripping rib 253b in opposite directions to each other and are formed in a T shape. In addition, the first gripping rib 253b and the second gripping rib 253b may be formed bent, unlike the illustrated case, and may extend at an angle toward the inner body 210.

[00329] In other words, the first gripping rib 253b and the second gripping rib 253c may extend from the free end of the protruding rib 253a parallel to one surface of the inner body 210, may extend at a distance from the inner body 210, or may be configured to extend toward the inner body 210.

[00330] In this case, the first gripping rib 253b and the second gripping rib 253c preferably extend toward the inner body 210 to maximize the engagement between the gripping rib 253 and the foaming agent, and may be configured to form a curve that is convex upward.

[00331] In this case, the first gripping rib 253b and the second gripping rib 253c may be formed in a plurality to be located at a distance from the free end of the protruding rib 253a, and may be symmetrically formed on the protruding rib 253a.

[00332] In this way, the foaming agent S can be solidified by surrounding the protruding rib 253a, the first gripping rib 253b and the second gripping rib 253c. Accordingly, the foaming agent S can be prevented from moving parallel to one surface of the inner body 210 by the protruding rib 253a and can be prevented from moving a large distance from the inner body 210 by the first gripping rib 253b and the second gripping rib 253c.

[00333] As a result, the adhesion between the inner body 210 and the foaming agent S can be maintained.

[00334] The gripping portion 250 may include a gripping ring 252 protruding from the inner housing 210 to the housing and connected for passing through the foaming agent S.

[00335] The gripping ring 252 may be configured to allow the foaming agent to pass through it and is formed in the form of a gripper.

[00336] In detail, the gripping ring 252 may include a ring body 252a configured to protrude from the inner body 210 in a “U” or “C” shape, and a ring opening 252b formed inside the ring body 252a to allow the foaming agent S to pass therein.

[00337] In this way, the foaming agent can pass to the outer side of the gripping ring 252 and then can be cured in the position in which it positions the gripping ring 252, and the gripping ring 252 can be positioned in the position in which it is embedded in the foaming agent S. Therefore, the foaming agent S can maintain the position connected to the gripping ring 252 to maintain adhesion to the inner body 210, even if the adhesion to the inner body 210 is weakened.

[00338] Since the gripping ring 252 has a small volume, the gripping ring 252 cannot disturb the movement of the foaming agent S.

[00339] In addition, the gripping portion 250 may include an anchor 254 configured to protrude from the inner body 210 toward the body 100. The anchor 254 may include a support 254b and a receiving portion 254a extending from the aforementioned support to the two parts.

[00340] In addition, the support 254b may have an outer peripheral surface formed in the form of a curve for guiding the foaming agent S for active movement in contact with the outer peripheral surface. The anchor 254a may be configured to taper toward the end and may be configured to pierce the inner part of the foaming agent S to fix the foaming agent if the foaming agent S is placed therein.

[00341] In this way, the foaming agent S and the inner body 210 can be firmly fixed.

[00342] The anchor 254 may be formed in a plurality such that the anchors may be located at a distance from each other along one surface of the inner body 210.

[00343] As shown in Fig. 16(b), the gripping portion 250 may include a plurality of protruding rods 255 configured to protrude from the inner body 210. The protruding rods 255 may be formed in a cylindrical or oval cross-section to guide the foaming agent S for easy passage, or may be formed in a polygonal cross-section to improve adhesion with the foaming agent S if it is placed in the foaming agent S.

[00344] The protruding rods 255 do not have a region for accommodating the foaming agent S, but can be easily molded or connected. If the protruding rods 255 are formed in a plurality, adhesion to the foaming agent S can be ensured.

[00345] In this case, the gripping section 250 may include a gripping blade 257 configured to bend from the inner housing 210 to the housing 100.

[00346] The gripping blade 257 may be formed with one end connected to the inner housing 210 and the other end extending toward the inner housing 210 or the region between the housing and the inner casing.

[00347] Thus, if the gripping blade 257 is located in the foamer S, the foamer S can be in contact and connected with the inner body 210 at different angles to improve the adhesion between the foamer and the inner body.

[00348] The gripping blade 275 may be located on the inner housing 210 in the plural, and its width may be configured to match the width of the inner housing 210 or less than its width.

[00349] In this case, the gripping portion 250 may include a gripping hook 257 protruding from the inner body 210 and fixed by being placed in the foaming agent S.

[00350] The gripping hook 257 may be configured to taper when passing from the inner housing 210, or may be configured to be inclined at a specific angle, or curved. The gripping hook 257 may be located on the inner housing 210 in a plurality and may be symmetrically located on the base of the injection holes 140.

[00351] In addition, the gripping hook 257 may extend with a projection from the inner housing 210 to both parts or more.

[00352] Thus, the gripping hook 257 cannot disturb the movement of the foaming agent S and can fix the foaming agent by piercing the foaming agent S if it is placed in the foaming agent S, as a result of which the foaming agent S can be prevented from being detached from the inner body 210.

[00353] Fig. 17 shows another embodiment of the gripping section.

[00354] The gripping portion 250 may include a gripping projection 254 configured to protrude from one surface of the inner casing 200 and be positioned in the foaming agent.

[00355] The gripping projection 254 may include a protruding support 2542 protruding from one surface of the inner body 210, and an upper member 2541 formed at a free end of the protruding support 2542 and having a diameter larger than the diameter of the protruding support.

[00356] The gripping projection 254 cannot disturb the movement of the foaming agent S since the volumes of the protruding base 2542 and the upper element 2541 are not large.

[00357] In addition, the upper member 2541 can be easily in contact with and accommodated in the foaming agent S, as a result of which the foaming agent S can be prevented from being separated from the upper member 2541 parallel to the inner body 210 and be at a distance from the inner body 210.

[00358] The gripping projection 254 may be formed on a side surface or a rear surface of the inner body 210 for being located at a distance from another gripping projection in a plurality, may be configured to be connected to the inner body 210, or may be configured to be molded integrally with the inner body 210.

[00359] In this case, the gripping section 250 may include a gripping opening 255, recessed from the inner housing 210 and fixed by the foaming agent inlet.

[00360] The gripping opening 255 may include an inlet opening 2551 recessed in the inner housing 210 and a receiving groove 2552 formed larger than the diameter of the inlet opening at the end of the inlet opening 2551 to provide an area into which the foaming agent passes.

[00361] Thus, if the foaming agent passes into the housing 100, the liquid foaming agent may penetrate into the inlet opening 2551 and may fill the receiving groove 2552.

[00362] As a result, since the foaming agent S is partially accommodated in the inner body 210 and connected to the inner body 210, the foaming agent S can be prevented from being separated from the inner body 210.

[00363] The gripping hole 255 may be formed on the side surface or the rear surface of the inner body 210 to be located at a distance from another gripping hole in the plurality, and a curved hole (not shown) may be further formed at the end of the groove 2552 to be positioned toward the surface of the inner body 210 to ensure easy passage of the foaming agent S.

[00364] Thus, the inner casing 200 of the present invention can maintain adhesion to the foaming agent S even if the inner casing is made of a material that does not provide adhesion to the foaming agent S.

[00365] Fig. 18 shows a structure in which the hinge assembly 600 and the base 500 of the laundry treating device 10 of the present invention are fixed to the body 100 simultaneously with the inner casing 200 and the hot air supply device 400 using the foamer S.

[00366] In this case, the laundry processing device 10 of the present invention comprises a hinge unit 600 configured to connect the door 180 for opening or closing the opening with the body. In this case, if the hinge unit 600 is connected to the body 100, etc., after the foaming process is completed, there is an inconvenience in that an additional assembly process is carried out.

[00367] In addition, if the hinge assembly 600 is connected to the housing 100, the inner casing 200, etc., by a bolt or a connecting member, a crack may occur in the foaming agent S located inside the housing 100.

[00368] In addition, if the base 500 is assembled separately after fixing the inner casing 200 and the hot air supply device 400 to the body 100, an additional assembly process is performed.

[00369] In addition, if the base 500 is connected to the hot air supply device 400 or the hot air supply device 400 or the lower portion of the body 100 by a connecting member such as a bolt, a crack may occur in the foaming agent S located inside the body 100 accommodated therein.

[00370] Therefore, the hinge assembly 600 and the base 400 may preferably be connected or secured to each other by the foaming agent S to simplify the assembly process, improve the performance and ensure the durability of the foaming agent S.

[00371] The laundry treating device 10 of the present invention may further include a hinge assembly 600 that rotatably connects the door 180 to the body 100. In this case, one or more hinge assemblies 600 and the base 500 may be configured to be fixed to the body 100 together with the inner casing 200 and the hot air supply device 400 when the inner casing 200 and the hot air supply device 400 are fixed with the foaming agent S.

[00372] In this way, the process of separately assembling and connecting the hinge assembly 600 to the base 500 can be eliminated, and a connecting member such as a bolt can be inserted into the foaming agent S.

[00373] The base 500 may include a base body 510 located on a lower portion of the hot air supply device 400 to form a lower surface of the body 100. The base body 510 may be formed in the form of a plate and made of an elastic material or of a polymer or metal material.

[00374] The base body 510 may comprise a body connection portion 520 in which the hot air supply device 400 is located. The body connection portion 520 is a region in which the lower surface of the housing 410 for accommodating is located, and may be configured to be in surface contact with the housing 410 for accommodating. The base body may be configured as a groove in which the lower surface of the housing 410 for accommodating is completely inserted and secured. In this way, the base 500 and the hot air supply device 400 can be securely connected to each other.

[00375] In this case, the base body 510 may include a leakage preventing block 530 extending further from the body connecting portion 520 to the side surface of the body 100. That is, the leakage preventing block 530 may be a portion extending further from the region where the body 410 for accommodating the base body 510 is located, to the side.

[00376] The leakage preventing block 530 may be configured such that the foaming agent S may be disposed thereon and connected thereto, as a result of which the foaming agent S may be prevented from leaking to the outside of the body 100. In addition, the leakage preventing block 530 may further include a foaming agent accommodating groove 531, into which the foaming agent S is inserted for being accommodated therein, to enhance the adhesion with the foaming agent S.

[00377] The plurality of curved openings 700 may be configured to guide the foaming agent S to pass into the foaming agent receiving groove 531 and to guide the foaming agent to be placed in the foaming agent receiving groove 531.

[00378] In this way, the foaming agent S can pass into the injection holes 140 and then simultaneously reach the outer side of the housing 410 for accommodating and the base 500. After that, the foaming agent S can further pass from the outer side of the housing 410 for accommodating and can be filled to reach the leakage preventing unit 530. As a result, the hot air supply device 400 and the base 500 can be simultaneously connected to the casing using the foaming agent, and the assembly process using a separate bolt can be eliminated.

[00379] In this case, the hinge assembly 600 may include an upper hinge 610 connected to the upper region of the casing to ensure a pivotable connection of the door therewith. The upper hinge 610 may be connected to the inner casing 200 or directly connected to the body 100.

[00380] However, the upper hinge 610 may be connected by an insert between the inner casing 200 and the body 100 to enhance the adhesion.

[00381] The upper hinge 610 may be inserted into the region between the inner casing 200 and the body to pass through this region, and may then be secured with the foaming agent S.

[00382] In detail, the protective rib 220 may include an upper through hole 630 at the upper portion, and the upper hinge 610 may be inserted into the upper through hole 630 by passing through the upper through hole 630. Thus, the upper hinge 610 may be inserted into the upper through hole 630 until the foaming agent S contacts the protective rib 220, as a result of which its position can be fixed.

[00383] The upper hinge 610 may include an upper housing 611 inserted into the upper through hole 630, and an upper hinge shaft 615 extending to a lower portion of the upper housing and configured to provide a rotary connection of the door with it. Thus, if the upper housing 611 is inserted into the upper through hole 630, the foamer S may also fix the upper housing 611 when fixing the inner casing 200. That is, the upper housing 611 may be connected to the foamer S by being completely accommodated in the foamer S.

[00384] In addition, the upper body 611 may further include an upper recessed groove 612 accommodating the protective rib 220, for accommodating the protective rib 220 therein, as a result of which its position cannot change when the foaming agent S expands. The upper recessed groove 612 may be formed with a width corresponding to the thickness of the protective rib 220, for partially accommodating the protective rib 220 therein.

[00385] In addition, the upper body 611 may further include a first coupling guide surface 613 having a concave and convex shape on the outer surface to further enhance the adhesion to the foaming agent S, thereby increasing the friction force.

[00386] The connecting guide surface 613 may be formed in the same shape as the upper recessed groove 612, or may be formed with a width different from the width of the upper recessed groove 612. The connecting guide surface 613 may increase the contact area with the foaming agent S and may enhance the adhesion of the upper hinge 610 fixed to the foaming agent S by partially accommodating the foaming agent S.

[00387] In this case, the laundry treating device 10 of the present invention may include a lower hinge 620 connected to the front portion of the hot air supply device 400 to provide a pivotable connection of the door thereto, and the lower hinge 620 may be configured to be connected between the hot air supply device 400 and the body 100.

[00388] In detail, the lower hinge 620 may be configured to be inserted between the hot air supply device 400 and the body 100 and secured to the foaming agent S.

[00389] The hot air supply device 400 may include a lower through hole 640 in the lower portion of the safety rib 430 to allow the lower hinge 620 to be inserted therein.

[00390] The lower through hole 640 may be configured to be connected to the upper surface of the base body 510. Thus, if the lower hinge 620 is inserted into the lower through hole 640, its lower surface may be located on the base body 610 and supported.

[00391] The lower hinge 620 may include a lower housing 621 inserted into the lower through hole 640 and a lower hinge shaft 625 extending to an upper portion of the lower housing 621 to provide a pivotable connection of the door thereto.

[00392] In this case, the lower body 621 may further include a lower recessed groove 622 accommodating the safety rib 430, for accommodating the safety rib 430 therein, as a result of which its position cannot change when the foaming agent S expands. The lower recessed groove 622 may be made with a width corresponding to the thickness of the safety rib 430, for partially accommodating the safety rib 430 therein.

[00393] In addition, the lower body 621 may further include a second connecting guide surface 623 having a concave and convex shape on the outer surface, for further enhancing the adhesion with the foaming agent S, thereby increasing the friction force. The second connecting guide surface 623 may be formed in the same shape as the lower recessed groove 622, or may be formed in a shape different from the shape of the lower recessed groove 622.

[00394] Thus, if the lower hinge 620 is inserted into the lower through hole 640, the lower hinge 620 can be fixed together with the housing 410 for accommodating and the base 500 when the housing 410 for accommodating and the base 500 are fixed with the foaming agent S. That is, the lower hinge 620 can be fixed in such a way that the lower housing 621 is accommodated in the foaming agent S.

[00395] In this way, the hinge assembly 600 and the base 500 can be fixed with the foaming agent S, and a separate assembly process can be eliminated.

[00396] Fig. 19 shows another embodiment of the laundry treating device 10 of the present invention.

[00397] The upper housing 611 of the upper hinge 610 may include a second housing 6112 inserted into the upper through hole 630 to contact the protective rib 220, and a first housing 6111 bent from the second housing to position the upper hinge shaft 625 on the lower portion.

[00398] The first body 6111 and the second body 6112 can be formed to be bent at an angle of 90°. Thus, when the second body 6112 is tightly engaged with the protective rib 220 and is connected to the foaming agent S, the second body 6112 can be tightly engaged with the protective rib 220, as a result of which the engagement of the upper hinge 610 can be strengthened.

[00399] In addition, the portion at which the first housing 6111 and the second housing 6112 are bent may be configured to be bent such that the upper housing 611 can be easily inserted and rotated.

[00400] In this case, the lower hinge 620 can be designed with the possibility of separate connection to the base body 500.

[00401] That is, the lower hinge 620 may include a first lower housing 620a connected to the base housing, and a second lower housing 620b connected to the first lower housing 620a and containing a lower hinge shaft 625.

[00402] The first lower body 620a may include a connection region 6211 connected to the base body and a connection portion 6222 for receiving extending from the connection region 6211 forward to form a region into which the second lower body 620b is inserted.

[00403] The connection region 6211 and the connection node 6222 for placement may be configured in a “U” or “C” shape.

[00404] In this case, the second lower housing 620b may include a connecting portion 6224 for insertion connected by insertion to a connecting portion 6222 for placement, and a protruding shaft portion 6223 extending to the connecting portion 6224 for insertion by bending and containing a lower hinge shaft 625.

[00405] The protruding shaft assembly 6223 and the insertion connecting assembly 6224 may be configured to bend at an angle of 90°.

[00406] The lower hinge 620 may be connected to a separate connecting element 800 and configured to stably support the load of the door 180.
