Description

washing and drying machine

technical field

The utility model relates to a washing and drying machine.

Background technique

In recent years, attention has been paid to the hygienic environment of the living space, and many sanitary equipment products for achieving sterilization, deodorization, etc. have been distributed in the market. In laundry products, washing and drying machines that have functions of disinfecting and deodorizing clothing, cloth products, leather products, toys, small items, etc. have also begun to be sold.

Generally, these washing and drying machines are provided with a dedicated program for putting objects into the washing tub and operating them for several tens of minutes. Regarding the specific means of sterilization and deodorization, for example, there are many methods such as heating in the tank, using ozone, and using chemicals, but basically heating is performed.

In addition, the inside of the tank of the washing machine is worrying as a place where bacteria and mildew are likely to occur. This is because a lot of moisture is maintained due to water or the like remaining in the washing machine. In addition, clothes worn by a person are kept in the washing tub until the washing machine is driven, and bacteria adhering to the worn clothes enter the tub as one of the causes. Furthermore, due to the launch of washing and drying machines, the airtightness of the washing tank has become higher, and the heat retention and moisture retention have been further improved.

Therefore, several methods for dealing with the bacteria and mold in the washing tub have been proposed for the washing machine. For example, there is a method of sufficiently drying the inside of the washing tub by heating means such as a heater. However, such a situation may occur: the user cannot judge when to dry and how often to perform drying to effectively prevent bacteria and mildew, so that the user frequently performs drying. When the frequency of using drying in this way increases, it takes a lot of time and electricity costs, and energy is wasted. Therefore, even if it is known that the method of drying the washing tub is a good method for dealing with bacteria and mildew, the user often cannot use it flexibly.

As another method for dealing with bacteria and mildew in laundry and washing tanks, there is also the addition of antimicrobial ingredients to resin parts or metal parts used in washing tanks to eliminate bacteria and prevent mold. For example, Patent Document 1 describes a method of covering the surface of a washing tank with a resin film blended with an organic microorganism growth inhibiting substance.

As another method, there is also proposed a method of supplying a sterilizing and antifungal component to the inside of the washing tub during washing. For example, Patent Document 2 discloses that by supplying Ag ions at the time of rinsing, clothes can be sterilized and antibacterial, and a washing tank can be sterilized and mold-proofed.

However, the conventional method of heating for sterilization and deodorization has the following problem: the user cannot judge how long and how many times the drying in the washing tank can effectively prevent bacteria and mildew, so the user frequently performs drying.

In addition, conventional sterilization and deodorization functions require heating, so there are restrictions on the target object in consideration of thermal stress. In this case, as in the normal drying function, many objects cannot be used, and it is complicated and difficult for the user to judge the objects that can be used. In addition, since heating must be performed for a long time, a lot of electricity is used. In addition, in deodorizing means and the like that atomize water to act on clothing, it is also considered that stress is applied to the clothing due to wetting with water.

In addition, in the washing machine disclosed in Patent Document 1, scum and the like adhere to the surface of the washing tub, and bacteria, mold, and the like may grow from the scum as a starting point. In this case, since bacteria, mildew, etc. grow on the surface of the washing residue, etc., the antibacterial components of the constituent parts of the washing machine do not come into contact with bacteria, mildew, etc., and cannot play an antibacterial effect. Doesn't quite work.

In addition, as in the washing machine of Patent Document 2, if the Ag ions required for anti-mold are supplied to the extent that the anti-bacteria effect is achieved, the laundry will be blackened, which will adversely affect the washing effect itself. In addition, the cost required to generate Ag ions cannot be ignored. Therefore, more economical means are desired for the sterilization and deodorization of laundry and washing tubs.

In addition, the outer tank 3 is connected with a water inlet pipeline 12 and a drain pipeline 13 by piping, and the water inlet and discharge from the outer tank 3 are completed by controlling the water inlet valve (not shown) and the drain valve. That is, the water supply device constituted by the water inlet pipe 12 , the water inlet valve, etc. supplies washing water into the outer tank 3 .

The operation of the washing process will be described in sequence. The door 9 is opened, and the laundry and detergent are put into the washing tub 2 . The operation of the washer and dryer 1 is started by operating an operation panel provided on, for example, an upper front surface of the washer and dryer 1 , and by controlling a control board provided on the inside of the operation panel or the like. A specified amount of water is injected into the outer tank 3 from the water inlet pipeline 12, and the washing tank 2 is driven to rotate by the motor 7, and the washing process starts. By the rotation of the washing tub 2, the laundry accommodated in the washing tub 2 repeats the agitation operation in which the agitating protrusions 10 provided on the inner peripheral wall of the washing tub 2 are lifted in the direction of rotation and dropped from a raised appropriate height. Therefore, the beating action and washing are applied to the laundry. After the required washing time, the soiled washing liquid is drained from the drain line 13 .

FIG. 7 is a perspective view showing the vicinity of the fixing plate of the atomizing discharge member of the dryer. FIG. 7 is a cross-sectional view showing the inside of the atomizing discharge member of the washing and drying machine.

The operation program of the washing and drying machine 1 according to the embodiment of the present invention includes a washing program for only washing, a drying program for drying only, a washing and drying program for continuous washing and drying, sterilization, There are 4 settings for deodorizing Nanoe program. Nanoe (registered trademark) is a charged ion, which is a coined word. As shown in Fig. 4 and Fig. 7, the Nanoe program utilizes the circulating air supply path 5 used in the air circulation in the outer tank 3 during the drying process. An electrostatic atomization generator 83 for generating electrostatic atomization particles 82 for sterilization and deodorization is provided in the middle of the circulating air supply path 5 . Then, air is blown from the circulating air blowing path 5, and the electrostatically atomized particles 82 are blown onto the objects in the outer tub 3 and the washing tub 2 .

Open mode setting. The operation of the Nanoe tank cleaning mode is performed with the washing tank 2 in a stationary state for about 60 minutes after the door 9 is opened and closed after the washing program ends.

In the washing and drying machine 1 according to Embodiment 1 of the present invention, each of the aforementioned hygienic programs is set at the same level as washing, drying, etc., and dedicated operation buttons are also provided. Electrostatic atomization generating particles 82 have strong oxidative decomposition ability to act on objects. Therefore, instead of using heat as in the past, it is possible to easily achieve sterilization, deodorization, and suppression of mold growth without worrying about risks such as deterioration of raw materials by merely supplying electrostatic atomization generating particles 82 . Such a washing and drying machine 1 has a dedicated program for blowing the electrostatically atomized particles 82 onto the clothes, small objects, etc. stored in the washing tub 2 or on the surface of the washing tub 2 and the outer tub 3 .

Therefore, by setting it as a dedicated program, the user can easily and safely select the most suitable operation according to the purpose, and the usability is improved.

The circulating air blowing path 5 will be described in detail. As shown in FIGS. 3 and 4 , the air blowing unit 15 is constituted by a centrifugal blower in which a centrifugal blower 15 a is accommodated in a scroll case 15 b. The heat pump device 39 and the blower unit 15 are hermetically connected to each other by fitting the suction connection port 15c of the scroll housing 15b to the suction discharge port 38a. Here, the suction and discharge port 38 a is formed in an end wall of the heat pump casing 38 on one end side in the left-right longitudinal direction in FIG. 3 .

Accordingly, the suction force of the blower unit 15 acts on the inside of the heat pump casing 38 . And, the suction force of the blower unit 15 acts on the inside of the outer tank 3 through the suction path 5a of the circulating air blowing path 5 and the filter box 5d from the suction inlet 38b. Therefore, the air in the outer tank 3 is sucked into the heat pump casing 38 to be dehumidified and heated by the evaporator 31 and the condenser 32 . The dry high-temperature air after dehumidification and heating is sucked into the scroll housing 15b through the suction outlet 38a and the suction connection port 15c, and then passes through the air supply of the circulating air supply path 5 from the blowing part 15d of the scroll housing 15b. The bellows connecting portion 5b and the air supply path 5c blow air into the outer tank 3 . By repeating this, the laundry in the washing tub 2 is dried. The electrostatic atomization generating device 83 is provided in the vicinity of the blowing part 15d. The suction inlet 38 b is arranged on the other end side of the heat pump casing 38 .

As shown in Figure 5, the electrostatic atomization generating device 83 is connected on the atomization discharge part 84, the transformer printed circuit board 85, the control printed circuit board 86, the component housing 87, the fixing plate 88, and the transformer printed circuit board housing 89. lead and unitized. Here, a transformer printed circuit board 85 is used to generate the high voltage. The control printed circuit board 86 is used to control the atomizing discharge. The element case 87 encloses the atomizing discharge member 84 to form the bypass path 15f. The fixing plate 88 is used to fix the atomizing discharge member 84 and constitutes the shape of the inlet and outlet of the bypass path 15f. The transformer printed circuit board 85 is enclosed in the transformer printed circuit board case 89 .

By providing the electrostatic atomization generating device 83 in the circulating air path 5, the electrostatic atomization generating particles 82 can be supplied to the washing tub 2 and the outer tub 3 with little structural change during the drying operation. In addition, the electrostatically atomized particles 82 cannot be expected to be diffusible like gas, but need to be blown onto the object by moving with the wind flowing in the circulating air flow path 5 . At this time, the electrostatically atomized particles 82 are generated when they pass through the aluminum heat exchange fins forming the evaporator 31 and the condenser 32 of the heat pump device 39, and the blades of the aluminum blower 15a used in the air blowing unit 15. Collision and a large number of disappearance, resulting in greater loss. In actual measurement, the electrostatically atomized particles 82 are attenuated by about 70% in the aluminum heat exchange fins, and are attenuated by about 25% in the aluminum blower 15a. Therefore, it is desirable that the electrostatic atomization generating device 83 is installed near the outer tank 3 without passing through the aluminum heat exchange fins and the aluminum blower 15a. The electrostatic atomization generating device 83 of the washing and drying machine 1 according to Embodiment 1 of the present invention is installed near the blowing part 15d of the air blowing unit 15 . Therefore, the transmission loss of the electrostatic atomization generating particles 82 to the washing tub 2 and the outer tub 3 can be minimized, and the sterilization, deodorization, and mildew suppression can be performed more effectively.

In addition, in the process of spraying electrostatic atomization generating particles 82 into washing tank 2 and outer tank 3 , it is necessary to operate electrostatic atomization generating device 83 while pressurizing and feeding circulating air. As mentioned above, as a function, only the integration of atomization and air supply can exert its effect. Therefore, it is indispensable to effectively blow and attach the electrostatically atomized particles 82 to the object by using the pressurized and conveyed circulating air optimized by the air blowing means.

In addition, the electrostatic atomization generating device 83 is disposed on the washing and drying machine main body 44 side completely separated from the movable part on the outer tank 3 side by the air blowing bellows connection part 5b. Thereby, the precise electrostatic atomization generating device 83 which is a push-button device is not installed on the side of the outer tank 3 which vibrates during dehydration, and durability reliability can be improved.

In addition, as shown in FIG. 4 , the electrostatic atomization generating device 83 is integrally formed with the blowing portion 15 d on the pressurized feeding air discharge side of the blower unit 15 . Specifically, as shown in FIG. 5 , an opening is provided on the wall surface of the scroll housing 15b, and the electrostatic atomization generating device 83 including the bypass path 15f is covered so as to be sealed and fixed. Thereby, it is not necessary to rearrange the electrostatic atomization generating device 83 in the air circulation path 5, and the system can not only have a simpler and less expensive structure, but also improve assemblability and reduce man-hours. In addition, as a function, it is only effective when atomization and air supply are integrated, so it is desirable to unitize in advance.

The electrostatic atomization generating device 83 has a main flow side path 15e and a bypass path 15f that branch into two in the unit and merge together, and the atomization discharge member 84 is arranged in the bypass path 15f. Thereby, since the discharge part of the atomizing discharge member 84 is configured to protrude directly into the bypass path 15f, it is possible to avoid generation of wind noise, decrease in circulating air volume, and the like which are to be feared.

In addition, by optimizing the branching ratio of the bypass path 15f, it is possible to structurally adjust the propagating rate of the electrostatic atomization generation particles 82 with the circulating air by changing the opening area of the fixed plate suction port 88a protruding into the bypass path 15f. The most suitable air volume and wind speed. In this structure, the optimum wind speed for releasing electrostatic atomization particles 82 is expected to be about 1 m/s, and the opening amount of the suction port 88a of the fixed plate is designed accordingly.

As shown in FIG. 6, in the exhaust side opening 88b portion of the fixed plate 88, the main flow side path 15e at the confluence of the bypass path 15f and the main flow side path 15e is parallel to the flow direction of the circulating air of the circulating air supply path 5. An air deflector 88c is arranged. Without the air deflector 88c, at the part where the paths once branched by the bypass path 15f rejoin, the air flow in the main flow side path 15e is turbulent, the overall circulation flow rate is reduced, and the noise is also increased. In addition, the air on the side of the branch flow (bypass path 15 f ) swirls in a swirling flow, and a large number of electrostatically atomized particles 82 disappear. However, the above problems can be prevented by arranging the wind guide plate 88c parallel to the flow direction of the circulating air in the main flow side path 15e of the merged portion.

As shown in FIG. 7, the atomizing discharge member 84 has a counter electrode 84b, a water supply device 84c, and a voltage application device 84d. By using the voltage application device 84d, a high voltage is applied between the discharge electrode 84a and the counter electrode 84b. The water reaching the discharge electrode 84a is electrostatically atomized. Here, the counter electrode 84b is arranged to face the discharge electrode 84a. The water supply device 84c supplies water to the discharge electrode 84a.

In Embodiment 1 of the present invention, feedback control is performed, and water is electrostatically atomized by applying a negative voltage of 4.85 kV between the discharge electrode 84a and the counter electrode 84b, so that the discharge current value at this time is about 6 μA.

The process of electrostatic atomization: by applying a high voltage to make the side of the discharge electrode 84a a negative electrode, the charge is concentrated, and the water attached to the surface of the discharge electrode 84a is formed into a cone shape to form a Taylor cone. In addition, charges are concentrated at the front end of the Taylor cone to become high-density, and Rayleigh splitting in which water is split and scattered by the repulsive force of the high-density charges is repeated. At this time, the wettability of the surface of the discharge electrode 84a is affected due to the formation of a Taylor cone. Therefore, when the wettability is small, a predetermined Taylor cone is not formed and electrostatic atomization cannot be performed. Therefore, it is necessary to ensure that the water on the surface of the discharge electrode 84a is prescribed amount.

The water supply device 84c has a cooling device composed of a Peltier element 84e. The discharge electrode 84a is cooled by this cooling device, and moisture (humidity) in the air is condensed on the front end surface of the discharge electrode 84a to supply water. Here, the amount of water required for electrostatic atomization is about 0.5ml/h. The end portion of the Peltier element 84e on the discharge electrode 84a side is a cooling portion 84f, and the end portion on the opposite side is a heat dissipation portion 84g. The cooling part 84f is connected to the discharge electrode 84a, and the heat radiation part 84g is connected to the heat radiation fin 84h.

The air flowing in the bypass path 15f of the electrostatic atomization generating device 83 is configured to flow in contact with the cooling fins 84h, and the flow of the air is utilized for heat dissipation during atomization discharge. In the case of the Peltier atomizing discharge unit, since the required amount of heat dissipation during the atomizing discharge is determined, the minimum wind speed is determined when the heat sink for heat dissipation is specified. In the structure of Embodiment 1 of this invention, it is necessary to ensure sufficient wind speed of 0.5 m/s or more and 0.5 m/s or more. By utilizing the air circulated in the circulating air supply path 5 for heat dissipation, the originally necessary heat dissipation device can be eliminated.

In addition, as shown in FIG. 1 and FIG. 2 , in the washing and drying machine 1 according to Embodiment 1 of the present invention, when the air in the outer tank 3 circulates through the circulating air supply path 5 , the filter box becomes a negative pressure relative to the atmospheric pressure. The 1st opening part 51 is provided in the periphery of 5d. The first opening 51 of the outside air intake portion 5h is connected to an on-off valve 5g and an outside air introduction passage 5e. Moreover, the 2nd opening part 52 is provided in a part of the circulating air supply path 5 near the filter case 5d where positive pressure or the dynamic pressure of circulating air acts with respect to atmospheric pressure. Furthermore, the circulating air discharge duct is connected to the second opening 52 to form the circulating air discharge portion 5i.

By opening and closing the on-off valve 5g, a part of the circulating air in the circulating air supply path 5 can be replaced with external air. In the special program for blowing electrostatically atomized particles 82, at least the on-off valve 5g needs to be opened at the initial stage of the process to replace the air in the outer tank 3 with outside air. The washing and drying machine 1 is designed to be highly airtight for drying. If the door 9 is closed, the air outside the machine and in the tank can hardly be replaced. Because there is a lot of water remaining in the washing machine, the relative humidity in the tank immediately exceeded 90% when the door 9 was closed. As an environment for discharging, high humidity is not suitable, and when the electrostatic atomization generating device 83 is operated, the relative humidity in the tank needs to be 85% or less. Therefore, by gradually replacing the air in the outer tank 3 with the outside air, it is possible to avoid causing abnormal discharge.

In this way, in the initial stage of the dedicated program, there is a process of opening the on-off valve 5g and increasing the air volume of the air blowing unit 15 to actively replace the air in the outer tank 3 with outside air. Specifically, the on-off valve 5g is always opened from the start of the program, and while the air in the outer tank 3 is replaced with outside air, the heat pump device 39 is operated for about 2 minutes after 3 minutes to perform a dehumidification operation, and the operation is confirmed to be stable. sex.

In addition, the dedicated program operates the electrostatic atomization generating device 83 while pressurizing and feeding the circulating air in the circulating air blowing path 5 by the air blowing unit 15 . By performing atomization and air blowing at the same time in this way, electrostatic atomization generating particles 82 can be effectively blown onto the object.

Next, the mechanism of the drying function of another cross section different from that of FIG. 8 will be described using FIG. 9 . Fig. 9 is a longitudinal sectional view of another part of the washing and drying machine according to Embodiment 2 of the present invention.

The drying function is composed of a heater (heating device) 137, a blower (air supply device) 138, and a blower casing (a part of the circulating air supply path) 139 that accommodates the heater 137 and the blower 138 inside, and the blower casing 139 is installed On the main body 129 of the washer dryer. A hot air inlet (a part of the air circulation path) 140 for receiving the air in the water tank 123 is provided on the trunk of the water tank 123 , and a hot air outlet 141 is provided on the back side of the water tank 123 .

In addition, a heat exchange path (a part of the air circulation path) 142 is integrally provided in the water tank 123 . One end of the heat exchange path 142 communicates with the hot air inlet 140 , and the other end is connected to the suction end 139 a of the blower case 139 through a first bellows hose (part of the circulating air supply path) 143 . The exhaust end 139b of the blower case 139 communicates with the hot air blowing port 141 through the second bellows hose 145 and the rear air blowing path 144 . Here, the rear air supply path 144 is integrally provided in the water tub 123 .

In addition, a rear through hole 146 is provided at a position corresponding to the hot air blowing port 141 on the back of the rotary drum 121 , so that the air from the hot air blowing port 141 is sent into the rotary drum 121 .

In the heat exchange passage 142 , a plate-shaped heat exchange member 147 is attached so as to incline downward from the front side toward the back side above the hot air inlet 140 . The heat exchange path 142 is divided into a lower heat exchange path 142 a and an upper heat exchange path 142 b by a heat exchange member 147 . The lower heat exchange path 142a and the upper heat exchange path 142b communicate with each other on the lower end portion 147b side of the heat exchange member 147 through the communication port 142c. The heat exchange path 142 is substantially U-shaped. The cooling water supply valve 148 regulates the cooling water supplied from the water supply pipe head portion 150 to the upper end portion 147 a side of the heat exchange member 147 through the cooling water hose 149 . The cooling water supply device is composed of a cooling water supply valve 148 , a cooling water hose 149 and a water supply pipe head 150 . In addition, the cross-sectional area of the upper heat exchange path 142b is larger than the cross-sectional area of the communication port 142c.

The drum-type washing and drying machine with the above structure executes the washing process, rinsing process, dehydration process and drying process through the control action of the control device 151 .

Next, the operation of the drum-type washing and drying machine configured as described above will be described. In addition, the operation from the washing process to the dehydration process is the same as the operation of the conventional washing and drying machine, so the description thereof will be omitted.

In the drying process, the air blown by the rotation of the blower 138 is heated to a predetermined temperature by the heater 137 as shown by the hollow white arrow in FIG. 9 . Then, the hot air is sent from the hot air outlet 141 to the bucket tank 123 through the second bellows hose 145 and the back air supply path 144, and then sent to the rotary drum 121 from the back through hole 146. The heated hot air removes moisture from the wet laundry that is being stirred in rotary drum 121 to become hot air with moisture. Then, the hot air with moisture is discharged from the rotary drum 121 through the through hole 122 into the bucket tank 123 , and then sent to the heat exchange path 142 from the hot air inlet 140 .

At this time, the cooling water supply valve 148 is in an open state. Cooling water falls from the water supply pipe head 150 to the upper end 147a side of the heat exchange member 147, flows through the upper surface 147c of the heat exchange member 147 as shown by the dotted arrow, and flows from the front end of the lower end 147b of the heat exchange member 147 to the bottom. The side of the heat exchange path 142a falls. Then, the cooling water is discharged into the water tub 123 from the drain hole 152 provided on the bottom surface of the lower heat exchange path 142 a and communicated with the water tub 123 , and is discharged out of the drum-type washing and drying machine through the drain path 132 .

The moist hot air sent from the hot air inlet 140 into the lower heat exchange path 142 a of the heat exchange path 142 first comes into contact with the lower surface 147 d of the heat exchange member 147 . At this time, the lower surface 147d is also cooled by the cooling water flowing through the upper surface 147c of the heat exchange member 147. Therefore, heat exchange is performed between the wet hot air and the lower surface 147d, and the wet hot air is dehumidified (first dehumidification). process).

Then, the moist hot air is sent to the upper heat exchange path 142b on the lower end portion 147b side of the heat exchange member 147 through the communication port 142c. At this time, the wet hot air rolls up the cooling water falling from the lower end portion 147b of the heat exchange member 147 and scatters it, exchanges heat with the scattered cooling water, and dehumidifies the wet hot air (the second dehumidification process). ).

Then, the moist hot air is sent to the upper heat exchange path 142b, and comes into contact with the upper surface 147c of the heat exchange member 147 and the cooling water flowing there. At this time, the flow direction of the cooling water is opposite to the flow direction of the wet hot air. Thereby, the wet hot air exchanges heat with the upper surface 147c of the heat exchange member 147 and the cooling water flowing there, and dehumidifies the wet hot air (third dehumidification process).

The moist hot air that has passed through the three dehumidification processes of the first dehumidification process, the second dehumidification process, and the third dehumidification process in this way becomes effectively cooled and dehumidified air. Then, the first bellows hose 143 is sent from the suction end 139 a of the blower casing 139 into the blower casing 139 to reach the blower 138 .

In addition, in the above process, the cross-sectional area of the upper heat exchange path 142b is larger than the cross-sectional area of the communication port 142c. Therefore, the flow velocity of the moist hot air in the upper heat exchange path 142b is lower than the flow velocity of the communication port 142c. Therefore, the scattered cooling water does not enter the blower casing 139 from the suction end 139a of the blower casing 139 along with the hot air, but falls onto the heat exchange member 147 in the middle of the upper heat exchange path 142b. As a result, water droplets do not reach the heater 137 .

In FIG. 9 , an electrostatic atomization generating device 83 is provided upstream of the blower 138 and downstream of the suction end 139a on a part of the circulating air supply path, and an on-off valve 90 for admitting outside air is provided. Same as the first embodiment of the present invention, the operation program of the washing and drying machine during drying has a washing program for only washing, a drying program for drying only, and a washing and drying program for continuous washing and drying. There are 4 types of dry program, nanoe program for sterilization and deodorization. The so-called Nanoe program is a special program that uses the circulating air supply path used in the air circulation in the bucket tank 123 in the drying process, and installs the electrostatic atomization generating device 83 in the middle of the circulating air supply path, and the electrostatic atomization generates The device 83 generates electrostatic atomization particles 82 for realizing sterilization and deodorization, and by opening the on-off valve 90, the upstream of the blower 138 becomes a negative pressure, so that the electrostatic atomization device 83 will not be affected by the heater. Due to the bad influence of the heat of 137, the particles 82 generated by electrostatic atomization are blown onto the object in the rotating drum 121 by blowing air. In this program, the rotation mode and the stationary mode of the rotary drum 121 can also be selected according to the object, and the operation time is about 35 minutes.

In addition, the Nanoe tank cleaning mode is set after the washing process is over, and the electrostatic atomization particles 82 are automatically blown and attached to the rotating drum 121 and the bucket tank 123 each time after the clothes are taken out, and the mode can be set to be on or off. The operation of this mode is performed in a state where rotary drum 121 is stationary for about 60 minutes after the lid 127 is opened and closed after the washing process is completed.

In the washing and drying machine according to Embodiment 2 of the present invention, each of the aforementioned hygienic programs is set at the same level as washing, drying, and the like, and dedicated operation buttons are also provided. Since the particles 82 produced by electrostatic atomization have a strong oxidative decomposition ability acting on objects, they can easily achieve sterilization, deodorization, and inhibition of mold growth. Therefore, by setting the dedicated program, the user can easily and safely select the most suitable operation for the purpose, thereby improving usability.

Through the above-mentioned air circulation, the laundry is gradually dried, and the drying process ends after a predetermined time elapses or when the laundry reaches a predetermined dryness.

As described above, in Embodiment 2 of the present invention, during the drying process, the flow velocity of the wet hot air in the upper heat exchange path 142b is lower than the flow velocity in the communication port 142c. Therefore, the scattered cooling water will not enter the blower casing 139 or the electrostatic atomization generating device 83 along with the hot air from the suction end 139a of the blower 139, and the electrostatic atomization generating particles 82 will not be scattered. Cooling water absorption. In addition, since the cooling water falls on the heat exchange member 147 in the middle of the upper heat exchange path 142 b, water droplets do not reach the heater 137 . Therefore, it is possible to prevent water from adhering to the heater 137 and causing an unsafe state, and to effectively dehumidify the air with moisture while ensuring safety. In addition, the electrostatic atomization particles 82 are not absorbed by water, and the electrostatic atomization particles 82 can be blown into the rotating drum 121 and the water tank 123 .

Next, Fig. 10 is another longitudinal sectional view of another part of the washing and drying machine according to Embodiment 2 of the present invention. In FIG. 10 , since the electrostatic atomization generating device 83 is provided near the hot air blowing port 141 , it is hardly affected by the heat of the heater 137 . In addition, since the air circulation path is located above the water level accumulated in the water tank 123 , the water accumulated in the water tank 123 is less likely to come into contact with the electrostatic atomization generating device 83 . Therefore, the generation of particles 82 by electrostatic atomization can sufficiently achieve sterilization, deodorization, and inhibition of mold growth.

In addition, like Embodiment 1 of the present utility model, a bypass path may be provided on a part of the circulating air supply path, and an electrostatic atomization generating device 83 may be provided in the bypass path, and the bypass path and the main flow side path The main flow side path of the confluence part is provided with an air deflector parallel to the flow direction of the circulating air.
