Description

Cleaner station {Cleaner station}

The present invention relates to a cleaner station coupled to a cleaner to collect dust inside a dust bin, and more particularly, to a member that collects and stores dust, which is not a dust bag that requires periodic replacement by a user. It relates to a cleaner station equipped with a bin-shaped dust collection container.

BACKGROUND ART In general, a vacuum cleaner is a home appliance that sucks up small garbage or dust and fills a dust bin in a product by a method of sucking air using electricity, and is commonly referred to as a vacuum cleaner.

Such cleaners may be classified into manual cleaners for cleaning while a user directly moves the cleaner, and automatic cleaners for performing cleaning while driving by itself. Manual cleaners may be classified into canister-type cleaners, upright cleaners, handheld cleaners, and stick-type cleaners according to the shape of the cleaner.

In household cleaners, canister-type vacuum cleaners have been widely used in the past, but recently, handheld vacuum cleaners and stick vacuum cleaners, which provide convenience in use by integrally providing a dust bin and a cleaner body, have been widely used.

The main body of the canister type vacuum cleaner is connected to the intake by a rubber hose or pipe, and in some cases, a brush can be inserted into the intake.

A handheld vacuum cleaner maximizes portability and is light in weight, but may have a limited cleaning area because of its short length. Thus, it is used to clean localized areas, such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used standing up, so you can clean without bending your back. Therefore, it is advantageous to clean while moving a large area. If the handheld vacuum cleaner cleans a narrow space, the stick type cleaner can clean a wider space and can clean high places that are out of reach. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

In addition, recently, robot cleaners that perform self-cleaning without a user's manipulation are commonly used. The robot cleaner automatically cleans the area to be cleaned by sucking foreign substances such as dust from the floor while traveling on its own in the area to be cleaned.

However, in conventional stick cleaners and robot cleaners, the capacity of the dust bin for storing the collected dust is small, and the user has to empty the dust bin every time, which is inconvenient.

In this regard, Korean Patent Publication No. 10-2020-0074001 discloses a cleaning device including a vacuum cleaner and a docking station.

The prior patent document discloses a cleaning device including a vacuum cleaner including a dust collection container in which foreign substances are collected, and a docking station connected to the dust collection container to remove foreign substances collected in the dust collection container. It is configured to include a suction device for sucking foreign substances in the dust collector.

In addition, the prior patent document is configured to include a collection unit for collecting foreign substances inside the docking station.

However, in one embodiment of the prior patent document, the collecting unit is composed of a dust bag, and thus requires periodic replacement, which is inconvenient. In addition, due to the characteristics of the material of the dust bag, a problem of dust scattering may occur during the process of being separated from the docking station for replacement.

On the other hand, in the prior patent document, an embodiment in which the collecting unit includes an additional dust collection container is disclosed. The additional dust collection box includes a multi-cyclone, and the air introduced into the additional dust collection box is configured to pass through the multi-cyclone, so that foreign substances discharged from the dust collection box of the vacuum cleaner can be collected by the additional dust collection box.

However, in another embodiment of the prior patent document, the multi-cyclone is configured to be accommodated inside the additional dust-collecting container, so there is a problem that the dust-accommodating capacity of the dust-collecting container is reduced by the volume of the multi-cyclone. Since the internal structure of the dust collection box becomes complicated when accommodated inside, it may be difficult for the user to manage the additional dust collection box, such as cleaning.

Referring to FIGS. 1 and 5 , the dust collection container 211 is disposed above the station main body 100 and may be provided to collect dust flowing together with the air. The dust collection container 211 may be provided in a cylindrical shape, and a longitudinal axis of the dust collection container 211 may be disposed parallel to a long axis of the station body 100 . A lower end of the dust collector 211 may be disposed to come into contact with an upper surface of the station body 100 and an upper end of the dust collector 211 may be opened. An upper end of the dust collection container 211 may be coupled to a blocking plate 222 to be described later, and at least a portion of an open upper end of the dust collection container 211 may be closed by the blocking plate 222 . The dust collection container 211 may be made of a transparent material through which the inside is visible. Through this, the user can grasp the degree of dust collection and can easily determine whether or not to empty the dust collected in the dust collector 211 . The dust collection container 211 may be made of a washable material. For example, the dust collector 211 may be made of a plastic material.

When the dust storage member provided in the cleaner station 10 is a bag-type dust bag, the user must periodically replace the dust bag. At this time, if the capacity of the dust bag is small, the user's convenience is reduced because the capacity of the dust bag is small, and on the contrary, if the capacity of the dust bag is large, the dust bag must wait until the dust bag is completely filled, so the replacement cycle becomes longer and the inside of the dust bag Bacterial growth can cause problems.

On the other hand, when a bin type dust collection box 211 is provided as a dust storage member as in the embodiment of the present invention, the dust collection box 211 is economical because it can be used semi-permanently without the need for replacement. In addition, since cleaning is possible and dust can be emptied and washed at any time, there is an advantage in that the cleaner station 10 can be managed more hygienically.

The dust collector 210 may further include a rotation unit 212 and a compression plate 213 .

5, 7 and 8, the rotating unit 212 is disposed inside the dust collection container 211 and arranged to rotate along the inner circumferential surface of the dust collection container 211 around the longitudinal axis of the dust collection container 211.

A lower end of the rotating shaft 2123 may be connected to a lower surface of the dust collection container 211 to receive power from the outside. The rotating shaft 2123 may extend adjacent to an upper end of the dust collection container 211 .

The rotation plate 2121 is connected between the rotation shaft 2123 and the scrubber 2122 and can rotate together with the rotation shaft 2123. The rotation plate 2121 may be formed in a shape in which one end of the rotation plate 2121 is connected to the rotation shaft 2123 and the other end extends radially outward from the dust collection container 211 . For example, the rotating plate 2121 may be formed in the shape of a square flat plate. The vertical length of the rotary plate 2121 may be formed to be similar to the length of the dust collection container 211 . When the rotary plate 2121 rotates together with the rotary shaft 2123, the wide surface of the rotary plate 2121 comes into contact with the wide surface of the compression plate 213 to be described later, and the dust collected between the rotary plate 2121 and the compression plate 213. can be compressed.

The scrubber 2122 may be coupled to the rotation plate 2121 at the opposite side where the rotation shaft 2123 is disposed. At this time, one side of the scrubber 2122 may be configured to touch the inner circumferential surface of the dust collection container 211 . Through this, the scrubber 2122 may scratch the inner circumferential surface of the dust collector 211 when rotating together with the rotating plate 2121 . The scrubber 2122 may be made of a material having ductility. For example, the scrubber 2122 may be made of a rubber material.

The compression plate 213 may be disposed in a fixed state on one side inside the dust collector 211 so that the rotating unit 212 rotates and compresses the collected dust. (See FIG. 8 ) The compression plate 213 is a compression plate. One end of the dust collector 213 may be connected to the inner circumferential surface of the dust collector 211 and the other end may extend radially inside the dust collector 211 . The compression plate 213 may be formed in substantially the same shape as the rotation plate 2121 . For example, the compression plate 213 may be formed in the shape of a square flat plate.

Meanwhile, referring back to FIG. 7 , the dust collector 210 may further include a dust compression motor 214 .

The dust compression motor 214 may provide power for rotating the rotation shaft 2123 . The dust compression motor 214 may be disposed outside the dust collection container 211 and may be connected to the rotary shaft 2123 through a lower surface of the dust collection container 211 . In one possible embodiment, the dust compression motor 214 may be directly connected to the rotary shaft 2123 through a shaft of the dust compression motor 214 provided to pass through the lower surface of the dust collector 211 . Alternatively, in one possible embodiment, the dust compression motor 214 and the rotating shaft 2123 may be connected through a dust compression gear unit 215 . At this time, the dust compression gear unit 215 may include at least one or more gear parts. A sensor capable of detecting a degree of rotation of the rotation shaft 2123 may be disposed on one side of the dust compression motor 214 to stop and control the rotation shaft 2123 . The sensor may be a micro switch.

The dust compression motor 214 may be controlled by a controller. In one possible embodiment, the direction of rotation of the dust compaction motor 214 may be reversed. For example, the rotation plate 2121 may rotate in the first direction to meet the compression plate 213 and compress dust. In addition, the rotation plate 2121 may rotate in a second direction opposite to the first direction to meet the compression plate 213 and compress dust.

As such, according to the embodiment of the present invention, the dust collected in the dust collection box 211 can be compressed and stored through the rotation unit 212 and the compression plate 213, and thus the collected dust compared to the capacity of the actual dust collection container 211 There is an effect of increasing the capacity of the dust that can be collected, so that the dust storage efficiency inside the dust collector 211 is increased, so user convenience can be increased. In addition, when the dust inside the dust collection container 211 is compressed, there is an effect of preventing the dust from scattering when the dust collection container 211 is emptied.

Meanwhile, the dust compression motor 214 and the dust collector 211 may be configured to be separable. That is, the dust compression motor 214 is disposed outside the dust collection container 211, and the rotary shaft 2123, the rotary plate 2121, and the compression plate 213 are accommodated inside the dust collection container 211, and the dust collection container ( 211) may be separated from the dust compression motor 214. As such, when the dust compression motor 214 is disposed outside the dust collection container 211, there is an advantage that the inside of the dust collection container 211 can be easily washed with water.

Next, the dust separator 220 will be described with reference to FIGS. 5 and 6 .

The impactor flow pipe 221 may be disposed on an upper outer portion of the dust collector 211 and provide a flow path through which air introduced through the suction flow path 130 flows. At this time, the impactor, as is known, is a phenomenon in which foreign matter particles such as dust entering through the inlet move along the flow path of the air, and the particles, which are large and receive a large inertial force, do not follow the flow and are collected. configuration that is used.

The impactor flow pipe 221 may be configured such that a direction in which dust moves inside the impactor flow pipe 221 is different from a direction in which a suction force acts on exhaust air exiting the impactor flow pipe 221 . Through this, dust contained in the air may be collected in the dust collector 211 by inertial force.

One end of the impactor passage pipe 221 may be connected to the suction passage 130 so that air flows in through the suction passage 130, and the other end of the impactor passage pipe 221 is open to allow air containing dust to escape. may have been

The blocking plate 222 is detachably coupled to the upper end of the dust collection container 211 and may serve as a cover for the dust collection container 211 . That is, the user can separate the dust collection container 211 and the station main body 100 after separating the dust collection container 211 and the blocking plate 222 . Through this, dust collected in the dust collection container 211 may be discharged and removed to the open upper end of the dust collection container 211 .

As a configuration meeting at right angles to , it is a configuration formed by extending downward by a predetermined length from the corner of the first cover portion 2231 . A lower end of the second cover part 2232 may be coupled to the blocking plate 222 . A lower end of the upper cover 223 is open and a space may be provided therein. That is, the upper end of the second cover part 2232 may be closed by the blocking plate 222 and the lower end of the second cover part 2232 may be open.

Meanwhile, in the dust separation space, relatively large dust may be separated from the air introduced from the station body 100 . The dust separation space is a space in which air flows and large particles of dust are separated, and at the same time, it may be a space in which the impactor flow pipe 221 is protected from external impact.

Hereinafter, the exhaust air moving unit 230 will be described with reference to FIGS. 5 and 6 .

The exhaust air movement unit 230 is configured to provide a space in which exhaust air from which dust is separated, which has exited the impactor flow pipe 221, is introduced and moved. The exhaust air moving unit 230 may be disposed above the station main body 100 (see FIG. 1 ). The exhaust air moving unit 230 may be disposed behind the dust collection container 211 . The exhaust air movement unit 230 may be disposed below the dust separation unit 220 .

Air discharged after large-particle dust is collected in the dust collector 211 may be filtered once more by the pre-filter 232 . The pre-filter 232 may be disposed to face a path through which exhaust air exits (see FIG. 6 ). In addition, the pre-filter 232 may be disposed at an outlet communicating with the dust collection motor 140 . In addition, the shape of the pre-filter 232 may be substantially the same as that of the outlet so that no air exits the outlet without passing through the pre-filter 232 . In addition, the shape of the pre-filter 232 may be configured to be substantially the same as the shape of the exhaust air passage hole 2222 to be described later.

A lower end of the suction passage connection pipe 231 may communicate with the first suction passage 130a. An upper end of the suction passage connection pipe 231 may communicate with the impactor passage pipe 221 (see FIG. 5). That is, one end of the impactor passage pipe 221 is connected to the suction passage connection pipe 231, It communicates with the first suction passage 130a, and through this, air that has passed through the dust bin 21 of the cleaner 20 and has flowed into the suction passage 130 can be transferred to the impactor passage pipe 221.

On the other hand, the blocking plate 222 communicates the inside of the dust collector 211 with the dust separation space, and has a dust passage hole 2221 provided to allow dust discharged from the impactor flow pipe 221 to pass through, and the dust separation space and discharge. It may further include an exhaust air passage hole 2222 provided to communicate with the air moving unit 230 and allow air discharged from the impactor flow pipe 221 to pass. (See FIG. 6 )

In addition, the impactor flow pipe 221 is connected to the first flow pipe 2211 extending in the vertical direction and the first flow pipe 2211 and extends in a direction perpendicular to the first flow pipe 2211 (horizontal direction). It may include a second flow pipe 2212 (see FIG. 5 ). One end of the first flow pipe 2211 may be connected to the suction flow passage connection pipe 231 and the other end of the first flow pipe 2211 may be connected to the second flow pipe 2212. One end of the second flow pipe 2212 may be connected to the first flow pipe 2211 and the other end of the second flow pipe 2212 may be open at a position adjacent to the dust passage hole 2221 .

Hereinafter, a process of collecting dust in the dust collection container 211 in the present embodiment will be described with reference to FIG. 6 .

The air introduced into the impactor passage pipe 221 through the suction passage 130 and the suction passage connection pipe 231 moves in the first direction D1 together with the dust. At this time, the suction force of the dust collecting motor 140 acts in the second direction D2 toward the exhaust air passage hole 2222 . That is, since the first direction (D1) and the second direction (D2) are directed in different directions, the moment the air is discharged from the open end of the impactor flow pipe 221, the inertial force, which is the force to continue moving the dust in the direction in which it was moving. It receives and continues to move in the direction D1, and the air flows in the direction D2 where the suction force acts and is introduced into the exhaust air moving unit 230.

At this time, in the impactor flow pipe 221, the suction force acts on the air in the dust separation space in the D1 direction, which is the direction in which the second flow pipe 2212 extends (or the direction in which the dust moves or the inertial force acts on the dust). It is possible to collect dust using inertial force only when it is formed to face in a different direction from the D2 direction, which is the direction to be used.

On the other hand, dust may be separated from the air moving in the D2 direction, continue to move in the D1 direction, collide with the upper cover 223, fall through the dust passage hole 2211, and be collected in the dust collector 211. The air moved in the direction D2 and introduced into the exhaust air moving unit 230 passes through the pre-filter 232 and is filtered once more, and then exhausted to the outside of the housing 110 .

Meanwhile, the dust separation unit 220 may further include a collision unit 224 .

Referring to FIG. 6 , the collision part 224 may be disposed along at least a part of an outer boundary of the dust passage hole 2221 inside the dust separation space. More specifically, the collision part 224 may extend vertically in the dust separation space and may be disposed in a region facing the open end of the impactor flow pipe 221 among the outer boundaries of the dust passage hole 2221. . That is, at least one surface of the impactor 224 may be disposed to face the direction of the inertial force acting on the dust exiting the impactor flow pipe 221 . The impact part 224 is connected to the semicircular first impact part 2241 connected to the inner wall of the second cover part 2232 and the first impact part 2241 when looking down at the dust separation space from the top, and the impactor passage A second collision part 2242 extending toward the tube 221 may be included. The second impact part 2242 extends parallel to the longitudinal axis of the second flow pipe 2212 of the impactor flow pipe 221 and may be arranged to form a predetermined gap from the outer circumferential surface of the second flow pipe 2212. there is.

Through this configuration, the air exiting the impactor flow pipe 221 collides with the impact part 224 and the flow direction along the inner wall surface of the impact part 224 can be rapidly changed. Therefore, it is more difficult for dust to follow the flow of air, and dust collection efficiency can be further increased.

According to an embodiment of the present invention, since large-particle dust is collected using inertial force, there is no need to provide a metal mesh net, which simplifies the dust separation structure and reduces the number of components that require washing, resulting in user convenience. This has a further increasing effect.

In addition, when the dust separation unit 220 is disposed outside the dust collection container 211 as in the present invention, there is an effect of increasing a space for storing dust inside the dust collection container 211 .

Referring to FIGS. 16 and 17 , in this embodiment, the louver 422 may guide air in a side inclined direction. That is, the louver 422 may be installed in the lateral opening of the impactor flow pipe 421 . In other words, the louver 422 is installed so that the directions D6 and D7 in which the louver 422 guides the air and the direction D5 in which the air flows inside the impactor flow pipe 421 face different directions. (See FIG. 16 ) Air containing dust is introduced into the first flow pipe 4211 and flows through the second flow pipe 4212 . Dust continues to move in the direction in which the air flows inside the second flow pipe 4212 by inertial force, passes through the dust passing hole 3231 coupled to the end of the second flow pipe 4212, and collects dust in the dust collector 211 ). (See Fig. 17)

At this time, the dust-separated air is guided by the louver 422 through the opening formed in the impactor flow pipe 421 and escapes. The air exiting the impactor flow pipe 421 flows into the cyclone unit 330, and fine-sized dust is separated by the flow of the cyclone (see FIGS. 12 and 15).

The exhaust air separated to fine-sized dust flows in the order of the first cyclone pipe 332, the cyclone suction part 331, and the dust collection motor connection pipe 342, passes through the dust collection motor 140, and enters the HEPA filter 150. After being finally filtered, it is discharged to the outside of the housing 110. (See FIGS. 1, 11 and 14)
