Description

Washing and drying machine Technical field

The present invention relates to a washer-dryer.

Background technique

In recent years, there have been a variety of products that focus on the environmental sanitation of living spaces and are concerned with hygiene for the purpose of sterilization and deodorization. Among the laundry products, a washing and drying machine having sterilization and deodorizing functions for clothes, cloth products, leather products, toys, small items, and the like is also sold.

These washing and drying machines generally put the object into the washing tank and set a dedicated stroke for several ten minutes of operation. The specific sterilization and deodorizing methods can be divided into various methods such as heating in the tank, using ozone, and using chemicals. But the basic principle is heating.

Moreover, there is a high risk of bacteria and mold in the tank of the washing machine. This is because the washing machine maintains high humidity due to residual moisture, and also because the clothes that will pass through are placed in the washing tub until the washing machine starts to operate. The bacteria adhering to the clothes that have passed through enter the tank, etc., and moreover, the appearance of the washing and drying machine improves the airtightness of the washing tub and further improves the moisturizing property.

Here, several methods for controlling bacteria and molds in the washing tub of the washing machine have been disclosed, for example, a method of sufficiently drying the inside of the washing tub by a heating device such as a heater, but if the user blows at any timing and frequency Dry washing tanks, because it is impossible to judge whether it can effectively prevent bacteria and mold, and frequently dry, if the frequency of drying is increased as described above, it will consume too much time and electricity, and violates the province. The principle of electricity, therefore, even if it is known that the method of drying the washing tank is quite suitable for controlling bacteria and mold, the user does not often use these methods.

As another method of controlling the bacteria and mold of the washing and washing tank, an antibacterial component is added to the resin part or the metal part used for the washing tank to perform sterilization and mildew prevention. For example, Patent Document 1 discloses a washing method. The surface of the tank is coated with a resin film in which an organic microorganism growth inhibiting substance is blended.

Further, another method of supplying the sterilizing and antifungal components to the inside of the washing tub during washing is disclosed. For example, Patent Document 2 discloses a method of sterilizing and sterilizing clothes by supplying Ag ions during rinsing. And a method of sterilization and mildew prevention on the washing tank.

However, in the conventional method of performing sterilization and deodorization by heating, if the user dries the washing tank at any timing and frequency, it is impossible to determine whether it is effective in preventing bacteria and mildew, and it is frequently dried. problem.

In addition, since heating has been used as a sterilization and deodorizing function in the past, the object is restricted in consideration of the heat pressure, and in this case, it cannot be used on a plurality of objects like the general drying function, and is used. It is quite cumbersome to judge the objects that can be used, and it takes a lot of power because of the long-time heating. In addition, even the deodorizing method of atomizing water and acting on the clothes needs to take into account the stress caused by the water on the clothes material.

Further, in the washing machine of Patent Document 1, there is a problem that the washing residue or the like adheres to the surface of the washing tub, and bacteria and molds are propagated from the place where it is confirmed. At this time, bacteria and molds are propagated on the surface of the washing dregs, etc. Therefore, the antibacterial component in the washing machine member does not come into contact with bacteria, mold, etc., and the antibacterial effect is not good, and even if the component is added, it is not effective.

Further, in the washing machine of Patent Document 2, if the Ag ions required for mold prevention are supplied to the extent that the antibacterial effect is exhibited, there is a risk that the blackening of the clothes adversely affects the washing effect itself, and Ag ions are generated. It is not expensive, therefore, a more economical method is needed for sterilization and deodorization of washings and washing tanks.

By the rotation of the washing tub 2, the laundry stored in the washing tub 2 is lifted in the rotational direction by the stirring projection 10 provided on the inner peripheral wall of the washing tub 2, lifted up to an appropriate height, and dropped, and the stirring is repeated. The action thus produces a knock on the laundry and washes it. The dirty washing liquid is discharged from the drain line 13 after the predetermined washing time. Then, the washing liquid contained in the laundry is extruded by the spin-drying operation of the washing tub 2 at a high speed, and then the water injecting pipe 12 is injected into the outer tank 3 to perform a rinsing stroke, and the rinsing stroke is accommodated in the rinsing stroke. The washings in the washing tub 2 continue to be lifted by the rotation of the washing tub 2 and the stirring protrusions to perform the rinsing operation, and the draining is started after the rinsing stroke ends, and the washing tank 2 is rotated at a high speed.

A perspective view of the vicinity of the fixed discharge plate of the atomization discharge module of the clothes machine, and Fig. 7 is a cross-sectional view showing the inside of the atomization discharge module of the aforementioned laundry dryer.

The operation stroke of the washer-dryer 1 according to the embodiment of the present invention can be set to only the laundry stroke of the laundry step, the drying process of only drying, the continuous laundry-drying of the laundry, the sterilization, and the sterilization. There are 4 kinds of scented Nanoe trips. Nanoe (registered trademark) means a charged ion, which is a self-made word. As shown in Fig. 4 and Fig. 7, the Nanoe stroke means the cycle used for the air circulation inside the outer tank 3 during the drying stroke. The air blowing path 5 is provided with an electrostatic atomization generating device 83 in the middle of the circulating air blowing path 5 to generate the electrostatic atomization generating particles 82 for sterilization and deodorization purposes, and the air is blown by the circulating air blowing path 5 to allow the outer tank 3 The inside and the object inside the washing tub 2 are exposed to the electrostatically atomized particles. Further, the Nanoe stroke can also select the rotation mode and the stationary mode of the washing tub 2 in accordance with the object, and the operation time is about 35 minutes.

However, a Nanoe in-slot cleaning mode is also provided, which automatically exposes the inside of the washing tub 2 and the outer tub 3 to the electrostatically atomized particles 82 each time after the laundry is taken out, and can be opened and closed. This mode is set, and the Nanoe in-slot cleaning mode operates within 60 minutes after the end of the washing process and the door body 9 is opened and closed, and the washing tub 2 is in a stationary state.

In the washer-dryer 1 according to the first embodiment of the present invention, each of the care-related strokes is designed to be equivalent to a stroke such as laundry or clothes, and a dedicated operation button is provided. Further, since the electrostatic atomization generating particles 82 have a strong oxidative decomposition ability acting on the object, unlike the conventional method in which heating is required, the electrostatic atomization generating particles 82 are supplied, that is, there is no risk of deterioration of the material. It is easy to achieve sterilization, deodorization, and inhibition of mold production. The washer-dryer 1 has a dedicated stroke for exposing the surface of the washing tub 2 and the outer tub 3 to the electrostatically atomized particles 82 in clothes, fittings, and the like housed in the washing tub 2.

Therefore, if it is set to a dedicated stroke, the user can appropriately and comfortably select according to the purpose, thereby improving the comfort of use.

Next, 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 fan, and the centrifugal fan 15a accommodates a centrifugal fan 15a in the scroll casing 15b. Moreover, the heat pump device 39 and the air blowing unit 15 are connected to each other by fitting the suction connection hole 15c of the scroll sleeve 15b to the suction discharge hole 38a, and sealingly connecting them to each other, and the suction discharge hole here. 38a is formed on the end wall of one end side of the heat pump casing 38 on the left and right longitudinal directions of Fig. 3.

Thereby, the suction force of the air blowing unit 15 acts in the heat pump casing 38, and the suction force of the air blowing unit 15 is generated from the suction introduction hole 38b through the suction passage 5a of the circulating air supply path 5, the filter box 5d, and generated in the outer tank 3. Therefore, the air in the outer tank 3 is sucked into the heat pump casing 38, and is dehumidified and heated by the evaporator 31 and the condenser 32. The dehumidified and heated dry high-temperature air passes through the suction discharge hole 38a. The suction connection hole 15c is sucked into the scroll sleeve 15b, and is blown into the outer tank 3 by the blow-out portion 15d of the spiral sleeve 15b through the air-spinning connection portion 5b of the circulating air supply path 5 and the air supply passage 5c, and is thus repeatedly baked. The laundry in the washing tank 2 is dried. Further, the electrostatic atomization generating device 83 is disposed in the vicinity of the blowing portion 15d, and the suction introduction hole 38b is disposed on the other end side of the heat pump housing 38.

As shown in FIG. 5, the electrostatic atomization generating device 83 connects the atomizing discharge module 84, the pressure-variable printed circuit board 85, the control printed circuit board 86, the component housing 87, the fixing plate 88, and the transformer substrate substrate 89 via wires. Unitized. Here, the pressure-changing printed circuit board 85 is used to generate a high voltage; the control printed circuit board 86 is used to control the atomization discharge; the element housing 87 is encapsulated in the atomization discharge module 84 and used to form the bypass path 15f; The atomization discharge module 84 is fixed to form an entrance and exit shape of the bypass path 15f; and the transformer printed circuit board casing 89 is packaged in the pressure-variable printed circuit board 85.

By providing the electrostatic atomization generating device 83 in the circulating air supply path 5, the electrostatic atomization generating particles 82 can be supplied to the washing tub 2 and the outside by lifting the operation during the drying operation without causing a structural change. Slot 3. Further, the electrostatic atomization generating particles 82 are not diffusible like a gas, and must move with the wind flowing in the circulating air blowing path 5 and expose the object therein, and when the electrostatic atomization generating particles 83 pass through the heat pump When the evaporator 31 of the device 39 and the aluminum heat exchange fins of the condenser 32 and the blade of the aluminum fan 15a used by the air blowing unit 15 collide and disappear, most of the loss occurs, and in actual test, The aluminum heat exchange fins are attenuated by about 70%, and the aluminum fan 15a is attenuated by about 25%. Therefore, the electrostatic atomization generating device 83 is preferably disposed not on the aluminum heat exchange fins or the aluminum fan 15a. Near the outer tank 3. In the washer-dryer 1 according to the first embodiment of the present invention, the electrostatic atomization generating device 83 is disposed in the vicinity of the blowing portion 15d of the air blowing unit 15, and therefore, the electrostatic atomization generating particles 82 are conducted to the washing tub 2 and the outer tub 3. The loss can be suppressed to a minimum, and sterilization, deodorization, and mold inhibition can be performed more efficiently.

In the process in which the washing tank 2 and the outer tank 3 are exposed to the electrostatically atomized particles 82, the electrostatic atomizing device 83 must be actuated while pushing the circulating air, as described above, in terms of efficiency, atomization and The integration of the air supply can be effective. Therefore, the most indispensable element is to press and push the optimized circulating air by the air blowing mechanism to efficiently expose the object to the electrostatic atomization generating particles 82.

Further, the electrostatic atomization generating device 83 is disposed on the side of the washing and drying machine main body 44 by the air-spinning and contracting connecting portion 5b, and is opened to the movable portion on the side of the outer tub 3, whereby electrostatic atomization as a precise key component is generated. Since the device 83 is not attached to the side of the outer tub 3 which vibrates during dehydration, durability reliability can be improved.

Further, as shown in Fig. 4, the electrostatic atomization generating device 83 is integrated with the blowing portion 15d on the blowing and pushing air side of the air blowing unit 15, specifically, as shown in Fig. 5, An opening is formed in the wall surface of the scroll sleeve 15b, and is covered by the electrostatic atomization generating device 83 (including the bypass path 15f) and sealed and fixed, thereby eliminating the need to re-circulate on the circulating air path 5. The electrostatic atomization generating device 83 is provided, and in addition to the system, in addition to the simple and inexpensive structure, the combination can be improved, the number of working hours can be reduced, and the integration of atomization and air supply can be achieved in terms of effectiveness. It is better to use the effect in advance.

The electrostatic atomization generating device 83 has a main flow side path 15e and a bypass path 15f which branch in two directions inside the unit and then merge, and an atomizing discharge module 84 is disposed in the bypass path 15f. The wind-cutting sound generated by the structure in which the discharge portion of the atomizing discharge module 84 directly protrudes in the bypass path 15f and the risk of a decrease in the circulating air volume are avoided.

Further, by appropriately adjusting the branch ratio to the bypass path 15f, it is possible to change the opening area of the fixed plate suction hole 88a which protrudes into the bypass path 15f to generate particles 82 for electrostatic atomization with circulating air blowing. The optimal air volume and wind speed are used for structural adjustment. In the present configuration, it is preferable that the optimum wind speed of the electrostatic atomization generating particles 82 is about 1 m/s, and the opening amount of the fixing plate suction holes 88a is designed in accordance with the data.

As shown in Fig. 6, the exhaust side opening 88b of the fixed plate 88 is partially provided with a wind guide plate 88c, and the wind guide plate 88c is located on the main flow side path 15e of the bypass portion 15f and the confluence portion of the main flow side path 15e. And in parallel with the circulating air flow direction of the circulating air supply path 5, if there is no wind guide plate 88c, the portion of the path which is branched by the bypass path 15f and then re-converges, the air flow disturbing the main flow side path 15e is generated. The turbulent flow causes the overall circulation flow to decrease and increase the noise. Moreover, the air on the side of the tributary (bypass path 15f) rotates in a spiral shape, and the electrostatic atomization generation particles 82 are largely eliminated, but by the mainstream in the confluence section The wind guide plate 88c is disposed on the side path 15e in parallel with the flow direction of the circulating air to prevent the aforementioned condition.

As shown in Fig. 7, the atomizing discharge module 84 includes a counter electrode 84b, a water supply device 84c, and a voltage applying device 84d. The voltage applying device 84d applies a high voltage between the discharge electrode 84a and the opposite electrode 84b. The water supplied to the discharge electrode 84a is electrostatically atomized, and here, the opposite electrode 84b is disposed in the opposite direction of the discharge electrode 84a, and the water supply means 84c supplies water to the discharge electrode 84a.

In the first embodiment of the present invention, a negative voltage of 4.85 kV is applied between the discharge electrode 84a and the counter electrode 84b to electrostatically atomize water, and feedback control is performed so that the discharge current value at this time is about 6 μA.

The process of electrostatic atomization causes the discharge electrode 84a side to be turned into a negative electrode by applying a high voltage, and while the charge is concentrated, the water attached to the surface of the discharge electrode 84a is pulled up in a conical shape to form a Taylor cone. Then, the charge on the tip of the Taylor cone is concentrated to a high density, and the counter-dynamic bounce of the high-density charge is repeated to break the water and cause Rayleigh scattering of the splash. At this time, the formation of the Taylor cone is affected by the wettability of the surface of the discharge electrode 84a. Therefore, if the wettability is low, the predetermined Taylor cone cannot be formed and the electrostatic atomization cannot be performed. Therefore, the surface of the discharge electrode 84a must maintain a predetermined amount of moisture.

The water supply device 84c has a cooling device constituted by a Peltier device 84e, and the discharge electrode 84a is cooled by the cooling device, and moisture (moisture) in the air is condensed on the front end surface of the discharge electrode 84a. Water is supplied, and the amount of water required for electrostatic atomization here is about 0.5 ml/h. A cooling portion 84f is formed at an end portion of the Peltier element 84e on the side of the discharge electrode 84a, and a heat radiating portion 84g is formed at an end portion on the opposite side, and the cooling portion 84f is connected to the discharge electrode 84a, and the heat radiating portion 84g is connected to the heat radiating blade 84h. .

The air flowing inside the bypass path 15f of the electrostatic atomization generating device 83 contacts the heat radiation blade 84h while flowing, and the gas flow is utilized for heat release when the atomization discharge is performed. In the case of the Peltier-type atomizing discharge unit, since the amount of heat required to be dissipated during the atomization discharge is fixed, if the heat-dissipating blade is determined, the minimum wind speed must be constant, and the structure of the first embodiment of the present invention is fixed. In the middle, a wind speed of 0.5 m/s or more is required, and a sufficient wind speed above this value must be ensured. The heat release means originally required can be deactivated by utilizing the circulating air in the circulating air supply path 5 during the heat release.

Further, as shown in Fig. 1 and Fig. 2, the washer-dryer 1 according to the first embodiment of the present invention is provided with a first opening 51, and the air of the first opening 51 located inside the outer tub 3 passes through the circulating air blowing path 5. In the periphery of the filter case 5d which is negatively pressurized with respect to the atmospheric pressure during the circulation, the opening and closing valve 5g and the external air introduction pipe 5e are connected to the first opening 51 to constitute the external air intake portion 5h. Further, the washer-dryer 1 according to the first embodiment of the present invention is provided with a second opening 52 which is located in the vicinity of the filter box 5d which is positively pressurized with respect to atmospheric pressure or which has a circulating air flow pressure. A part of the air blowing path 5 is connected to the second opening portion 52 to which the circulating air discharge pipe 5f is connected to constitute the circulating air discharging portion 5i.

By the opening and closing of the on-off valve 5g, the circulating air of the partial circulation air supply path 5 can be exchanged with the outside air. When performing a dedicated stroke exposed to the electrostatically atomized particles 8, the on-off valve 5g must be opened at least in the early stage of its stroke to exchange the air in the outer tank 3 with the outside air, because the washer-dryer The airtightness of 1 is designed to be high for drying. If the door body 9 is closed, the air outside the machine and the tank are hardly interchangeable, and as long as the washing machine seldom retains moisture, the door body 9 is closed. The relative humidity in the tank immediately rises to 90%. Such high humidity is very unsuitable for the environment in which the discharge is performed, and even when the electrostatic atomization generating device 83 is actuated, the relative humidity in the tank must be 85% or less. By allowing the outside air to slowly exchange with the air in the outer tank 3, it is possible to prevent an abnormal discharge from occurring.

At the beginning of the dedicated stroke, there is a stroke of opening the on-off valve 5g and increasing the air volume by the air supply unit 15, and actively exchanging the outside air with the air inside the outer tank 3, specifically, when the stroke starts The on-off valve 5g is kept open forever, and the outside air is exchanged with the air in the outer tank 3, and the heat pump device 39 is operated for 3 minutes after the start of the stroke to perform the dehumidification operation for about 2 minutes, and the operation stability is ensured.

Further, in the dedicated stroke, the circulating air in the circulating air blowing path 5 is squeezed by the air blowing unit 15, and the electrostatic atomizing device 83 is actuated, whereby the object is efficiently exposed by atomization and air blowing at the same time. Electrostatic atomization produces particles 82.

Further, the exhaust end 139b of the fan cover 139 passes through the second telescopic hose 145 and the rear air supply path 144 which is integrally provided with the water tank 123, and the warm air. The air blowing holes 141 are in communication.

Further, the back surface of the rotary drum 121 is configured such that a rear surface through hole 146 is provided at a position corresponding to the warm air blowing hole 141, and the wind from the warm air blowing hole 141 is sent into the rotary drum 121.

In the heat exchange path 142, a plate-shaped heat exchange member 147 which is inclined from the front side toward the back side is provided above the warm air suction hole 140, and the heat exchange path 142 is divided into lower heat exchange by the heat exchange member 147. The path 142a and the upper heat exchange path 142b, and 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 hole 142c, and the heat exchange path 142 is substantially U-shaped. shape. The cooling water supply valve 148 is for adjusting the cooling water supplied from the water supply port portion 150 to the upper end portion 147a side of the heat exchange member 147 through the cooling water hose 149, and the cooling water supply valve 148, the cooling water hose 149, and the water supply. The mouth portion 150 constitutes a cooling water supply device. Further, in this configuration, the cross-sectional area of the upper heat exchange path 142b is larger than the cross-sectional area of the communication hole 142c.

The drum-type washer-dryer of the above configuration performs the washing stroke, the rinsing stroke, the dehydration stroke, and the drying stroke by the control action of the control device 151.

The operation of the drum type washer-dryer of the foregoing configuration will be described below. Further, since the operation from the washing stroke to the dehydration stroke is the same as that of the conventional washer-dryer, the description thereof will be omitted.

In the drying process, as indicated by the hollow arrow in Fig. 9, the air sent by the rotation of the fan 138 is heated to a predetermined temperature by the heater 137, and is heated by the second telescopic hose 145 and the rear air supply path 144. The air blowing hole 141 blows air into the water tank 123, and further blows air into the rotating drum 121 through the back through hole 146. The heated warm air is sucked by the moist washing in the agitating state in the rotating drum 121 to become a warm air with moisture. Thereafter, the warm air with moisture is discharged from the inside of the rotary drum 121 through the through hole 122 to the water tank 123, and then blown into the heat exchange path 142 by the warm air suction hole 140.

At this time, the cooling water supply valve 148 is in an open state, and the cooling water flows from the water supply port portion 150 to the upper end portion 147a side of the heat exchange member 147, and flows to the upper surface 147c of the heat exchange member 147 by heat exchange as indicated by a broken line arrow. The front end portion of the lower end portion 147b of the member 147 flows to the lower heat exchange path 142a side. Then, the cooling water is discharged into the water tank 123 by the drain hole 152 provided in the bottom surface of the lower heat exchange path 142a and communicating with the water tank 123, and is discharged to the outside of the drum type washing and drying machine through the drain path 132.

The humid warm air that is sent from the warm air suction hole 140 to the lower heat exchange path 142a of the heat exchange path 142 is first brought into contact with the lower surface 147d of the heat exchange member 147. At this time, since the cooling water flowing on the upper surface 147c of the heat exchange member 147 also causes the lower surface 147d of the heat exchange member 147 to be cooled, heat exchange between the moist warm air and the lower surface 147d is performed, and the humid warm air is dehumidified. (1st dehumidification step).

Then, the moist warm air is sent to the upper heat exchange path 142b through the communication hole 142c at the lower end portion 147b side of the heat exchange member 147. At this time, the humid warm air winds up the cooling water dropped by the lower end portion 147b of the heat exchange member 147 to be scattered, and performs heat exchange with the scattered cooling water to dehumidify the humid warm air (second dehumidification) step).

Then, the moist warm air is sent to the upper heat exchange path 142b, in contact with the upper surface 147c of the heat exchange member 147 and the cooling water flowing therethrough. At this time, the flow direction of the cooling water is opposite to the flow direction of the humid warm air, whereby the humid warm air exchanges heat with the upper surface 147c of the heat exchange member 147 and the cooling water flowing therethrough to dehumidify the humid warm air. (3rd dehumidification step).

In this manner, the humid warm air is efficiently cooled and becomes dehumidified air through the first dehumidifying step, the second dehumidifying step, and the third dehumidifying step, and then passes through the first telescopic hose 143 by the fan cover 139. The suction end 139a is sent to the fan cover 139 to reach the blower fan 138.

Further, in the foregoing step, the cross-sectional area of the upper heat exchange path 142b is larger than the cross-sectional area of the communication hole 142c, so the flow velocity of the humid warm air in the upper heat exchange path 142b is lower than the flow velocity of the communication hole 142c, whereby the scattered cooling water It does not enter the fan cover 139 from the suction end 139a of the fan cover 139 along the flow of the warm air, but falls on the heat exchange member 147 in the middle of the upper heat exchange path 142b, so that the water droplets do not drip Heater 137.

In Fig. 9, a part of the circulating air supply path is upstream of the blower fan 138, and an electrostatic atomization generating means 83 is provided downstream of the suction end 139a, and an on-off valve 90 for introducing outside air is provided. As in the first embodiment of the present invention, when drying, the operation stroke of the washer-dryer includes a laundry process in which only the laundry step is performed, a drying process in which only drying is performed, and a laundry which is continuously washed and dried. There are 4 kinds of Nanoe trips for clothing trips and sterilization and deodorization. The Nanoe stroke means a circulating air supply path used for circulating air inside the water tank 123 during the drying stroke, and an electrostatic atomization generating device 83 is provided in the middle of the circulating air supply path to achieve sterilization and deodorization purposes. The electrostatic atomization generates particles 82, and opens the on-off valve 90 to turn the upstream of the blower fan 138 into a negative pressure, so that the electrostatic atomization generating device 83 is not adversely affected by the thermal energy of the heater 137, and The object in the rotary drum 121 is exposed to a special stroke in the electrostatic atomization generating particles 82 by blowing air. The stroke can also select the rotation mode and the stationary mode of the rotary drum 121 in response to the object, and the operation time is about 35 minutes.

However, a Nanoe in-slot cleaning mode is also provided, which automatically exposes the inside of the rotating drum 121 and the water tank 123 to the electrostatically atomized particles 82 each time after the laundry stroke ends and the clothes are taken out, and can be opened and The mode setting is turned off, and the Nanoe in-slot cleaning mode operates within 60 minutes after the laundry stroke ends and the door body 127 is opened and closed, and the rotary drum 121 is in a stationary state.

In the washer-dryer according to the second embodiment, each of the care-related strokes is designed to be equivalent to a stroke such as laundry or clothes, and a dedicated operation button is provided. Further, since the electrostatic atomization generating particles 82 have a strong oxidative decomposition ability acting on the object, the purpose of sterilization, deodorization, and mold inhibition can be easily achieved, and therefore, if it is set to a dedicated stroke, the user can simply And the appropriate choice according to the purpose, improve the comfort of use.

With the aforementioned air circulation, the laundry is gradually dried, and after a predetermined time or when the laundry reaches a predetermined dryness, the drying process is terminated.

As described above, in the second embodiment of the present invention, when the dry clothes stroke is performed, the flow velocity of the humid warm air in the upper heat exchange path 142b is lower than the flow velocity of the communication hole 142c, whereby the scattered cooling water does not follow. The flow of the warm air enters the fan cover 139 from the suction end 139a of the fan cover 139, the inside of the electrostatic atomization generating device 83, and the like, and the electrostatic atomization generating particles 83 are not absorbed by the scattered cooling water, and are cooled. The water falls onto the heat exchange member 147 in the middle of the upper heat exchange path 142b, so that the water droplets do not drip onto the heater 137, so that the water can be prevented from adhering to the heater 137 in such an unsafe state, and safety is ensured. The air with moisture is dehumidified efficiently, and the electrostatic atomization generating particles 82 are not absorbed by the moisture, and the inside of the rotating drum 121 and the water tank 123 can be exposed to the electrostatic atomization generating particles 82.

Next, Fig. 10 is a longitudinal sectional view showing another portion of the washer-dryer according to the second embodiment of the present invention. In Fig. 10, since the electrostatic atomization generating device 83 is provided in the vicinity of the warm air blowing hole 141, it is less likely to be affected by the thermal energy of the heater 137. Further, since the circulating air blowing path is located at a place where the water level is accumulated inside the water tank 123, the water accumulated inside the water tank 123 does not easily come into contact with the electrostatic atomization generating device 83, so that the particles 82 can be sufficiently generated by electrostatic atomization. Sterilize, deodorize, inhibit the growth of mold.

Furthermore, as in the first embodiment of the present invention, a bypass path may be provided in a part of the circulating air supply path, and an electrostatic atomization generating device 83 may be provided on the bypass path, and the bypass path and the main flow side may be provided. A wind guide plate is disposed on the main flow side path of the confluence portion of the path, and the wind guide plate is parallel to the flow direction of the circulating air.
