Description

Washing and drying machine

Technical field

The invention relates to a washer-dryer.

Background technique

In the past, a washing and drying machine has been known which is equipped with a so-called pulsator washing machine (automatic washing machine) that washes clothes by generating a water flow in a washing and dewatering tank by a pulsator disposed at the bottom of the washing and dewatering tub. The drying function of the clothes. For example, Patent Document 1 describes an example of such a washer-dryer.

In the washing and drying machine of Patent Document 1, a warm air supply unit for supplying high-temperature air to the washing and dewatering tub is disposed on the upper panel having the laundry inlet. The opening of the upper surface of the tub provided with the washing and dewatering tub is covered by an outer tub having an inner lid. The inner lid opens and closes the inlet of the laundry formed on the outer tub.

The warm air generated by the warm air supply unit is blown from above the outer tub into the washing and dewatering tub through a warm air duct connected to the outer tub. An air vent is formed in the inner lid, and warm air supplied into the washing and dewatering tub reaches the outer side of the outer tub from the air outlet, and is discharged to the outside of the body from a vent hole or the like on the back surface of the outer casing.

In the outer tub cover, in addition to the warm air duct, a water supply pipe for supplying water into the washing and dewatering tub is connected. The warm air duct and the water supply duct are bellows-like, and can be swung even if the outer tub swings.

As described above, the structure in which the warm air from the outer tub is discharged to the inside of the outer casing has a hidden danger of condensation occurring inside the outer casing due to the moisture contained in the warm air. Therefore, it is conceivable to adopt a configuration in which an exhaust passage for discharging warm air from the outer tub to the outside of the body is provided, and the exhaust passage is connected to the outer tub via a swingable exhaust duct.

However, when the number of pipes connected to the outer tub is increased, correspondingly, it is possible to cause the input port formed in the outer tub to become small. In addition, there is a hidden danger that the balance of the outer tub is deteriorated by being pulled by these pipes, and the vibration of the outer tub becomes large at the time of dehydration.

Summary of the invention

Problems to be solved by the invention

The present invention has been made in view of such problems, and an object of the invention is to provide a washer-dryer capable of suppressing an increase in the number of pipes connected to an outer tub and discharging warm air from the outer tub to the outside of the body.

Solution to solve the problem

The washing and drying machine of the main embodiment of the present invention comprises: an outer tub elastically supported in the casing; a washing and dewatering tub rotatably disposed in the outer tub to receive the laundry; and a drying device for drying The laundry in the washing dewatering tub; and the water supply path including a flexible water supply pipe connected to the outer tub for the water supplied to the outer tub to flow. Here, the drying device includes: a heater; a blower fan; a flexible air inlet duct connected to the outer tub, guiding warm air generated by operation of the heater and the blower fan to the And an exhaust air passage connected to the water supply road to discharge warm air flowing from the outer tub through the water supply passage to the outside of the casing.

According to the above configuration, since the water supply pipe can be used as a flexible pipe for connecting the exhaust passage to the outer tub, it is possible to adopt a configuration in which the exhaust passage is provided to discharge the warm air in the outer tub to the outside of the casing. The number of flexible pipes connected to the outer tub is suppressed from increasing.

According to the above configuration, it is possible to suppress the warm air from flowing to the upstream side of the water flow at the connection port with the exhaust passage in the water supply path.

In the case where the above configuration is employed, the opening and closing valve may be configured to be opened by being inclined downwardly with the fixing portion at one end as a fulcrum. In this case, the connection port is provided on the side of the fixing portion.

As long as this structure is adopted, when water is supplied to the outer tub, water passing through the opening and closing valve is difficult to reach the connection port, and it is difficult for water to penetrate into the exhaust passage.

In the washing and drying machine of the present embodiment, the water supply path may be formed to protrude inward so as to cover the connection port on the upstream side of the water flow at the connection port of the water supply path and the exhaust air path. Highlights.

According to the above configuration, since the water flowing through the water supply path is rebounded by the protruding portion away from the connection port, it is difficult for water to seep into the exhaust passage.

In the washer-dryer according to the present embodiment, the exhaust duct may include a configuration in which an inclined path extending obliquely upward from the water supply path is employed.

According to the above configuration, even if water permeates into the exhaust passage, the water is easily returned to the water supply passage by the inclination of the inclined passage.

It should be noted that the drying device may also adopt a structure including: a flexible exhaust duct connected to the outer tub for passing warm air discharged from the outer tub; and a circulating air passage. Connecting the air inlet duct and the exhaust duct to circulate warm air between the circulation air duct and the outer tub; and an external air intake port for taking in outside air into the circulating air road.

According to this configuration, the warm air can be circulated between the circulation air passage and the outer tub to maintain the high temperature in the outer tub, and a part of the warm air containing the moisture in the outer tub can be discharged to the outside of the casing, thereby promoting Drying of the laundry. Further, in the case of adopting such a configuration, it is possible to avoid further adding a pipe corresponding to the exhaust passage on the basis of the three pipes of the intake duct, the exhaust duct, and the water supply duct to which the outer tub has been connected.

Effect of the invention

According to the present invention, it is possible to provide a washer-dryer capable of suppressing an increase in the number of pipes connected to the outer tub and discharging the warm air from the outer tub to the outside of the body.

Thereby, the inlet filter chamber 250 and the exhaust filter chamber 260 are partitioned by the partition plate 350 and the partition frame 270, and the communication between the inlet air filter chamber 250 and the exhaust filter chamber 260 is blocked. Moreover, the filter chamber 220, ie, the exhaust filter chamber 260, is closed by the front surface panel 330. In this state, the insertion port gasket 333 abuts against the peripheral edge portion of the insertion opening 221 in the insertion direction.

As shown in FIG. 10, the air inlet filter 311 is disposed obliquely in the air inlet filter chamber 250 so as to block between the left side surface 250a and the right side surface 250c, and is disposed in the external air introduction port 251 and the internal air introduction port 252. Between the outlets 253. Further, the outside air circulation port 323 and the internal air flow port 324 of the intake air holding frame 321 are opposed to the external air introduction port 251 and the internal air introduction port 252, respectively.

As shown in FIG. 11 and FIG. 12, the exhaust filter 312 is disposed in the exhaust filter chamber 260 so as to be obliquely disposed between the left side surface 260a and the right side surface 260c in the exhaust air introduction port 261 and the exhaust air guide. Between exits 262. Further, the exhaust air flow port 325 of the air discharge holding frame 322 is opposed to the air discharge introduction port 261.

It should be noted that the air inlet path 210 and the air inlet filter chamber 250 of the air passage unit 52 together with the casing 100 of the warm air generating unit 51 constitute a circulation air passage 50a through which the heating air circulates between the air and the outer tub 20.

The air inlet duct 54 is a flexible duct formed of an elastic material such as rubber, and the intermediate portion has a snake abdomen 54a. Similarly, the exhaust duct 55 is also a flexible duct formed of an elastic material such as rubber, and the middle portion has a snake abdomen 55a. As shown in Fig. 2, in the outer tub cover 20b, an air inlet 22b and an air outlet 22c are formed behind the inner inlet port 22a, and the lower end portion of the air inlet duct 54 is connected to the air inlet 22b, and the lower end portion of the air duct 55 is connected. At the exhaust port 22c.

Referring to FIGS. 3, 11, and 12, the water supply device 60 includes a water supply unit 61, a water supply valve 62, a bath water pump 63, and a water supply pipe 64. The water supply unit 61 includes a water supply tank 410, a detergent container 420 that can enter and exit the water supply tank 410, and a water supply pipe 430 through which water discharged from the water supply tank 410 passes. It should be noted that the water supply path 60a through which the water supplied to the outer tub 20 flows is constituted by the water supply unit 61 and the water supply pipe 64.

The water supply tank 410 is provided with a water passage 411 at the upper portion, and a water supply valve 62 and a bath water pump 63 are connected to the water passage 411. Further, a water supply port 412 is formed on the bottom surface of the water supply tank 410, and a water supply pipe 430 is connected to the water supply port 412. A detergent and a softener are contained in the detergent container 420. The detergent container 420 enters and exits the water supply tank 410 in the outside inlet port 14.

In the water supply pipe 430, a branch port 431 is formed on the inner surface on the right side, and a branch pipe 440 extending obliquely upward is integrally formed with the water supply pipe 430 so as to branch from the branch port 431. The branch pipe 440 is connected to the exhaust air introduction port 261 of the exhaust filter chamber 260. In the water supply pipe 430, on the upstream side of the branch port 431, that is, on the upstream side of the water flow of the branch port 431, a flange-like projecting portion 432 that protrudes inward is formed. It should be noted that the branch port 431 corresponds to the connection port of the present invention, and the branch pipe 440 corresponds to the inclined path of the present invention.

The water supply port 412 of the water supply tank 410 is provided with a check valve unit 450 whose water supply port 412 is on the upstream side of the water flow of the branch port 431 of the water supply pipe 430 and on the downstream side of the water flow of the detergent container 420.

The check valve unit 450 includes a ring portion 452 having a water outlet 451, and a bottom valve 453 that blocks the water outlet 451 from below. The bottom valve 453 is formed of an elastic material such as rubber, and a fixing portion 453a at one end thereof is fixed to the ring portion 452. The bottom valve 453 is maintained at a position where the water discharge port 451 is blocked by the elastic force thereof, and when the force of the water flow increases, the fixed portion 453a is tilted and sag as a fulcrum to open. The branch port 431 of the water supply pipe 430 is provided on the side of the fixing portion 453a of the bottom valve 453. It should be noted that the bottom valve 453 corresponds to the on-off valve of the present invention.

The water supply pipe 64 is a flexible pipe formed of an elastic material such as rubber, and the intermediate portion has a snake abdomen 64a. The upper end portion of the water supply pipe 64 is connected to the water supply pipe 430. As shown in Fig. 2, in the outer tub cover 20b, a water supply port 22d is formed behind the inner inlet port 22a, and a lower end portion of the water supply conduit 64 is connected to the water supply port 22d.

It should be noted that the branch pipe 440 constitutes an exhaust passage 50b for discharging warm air to the outside of the fully automatic washer-dryer 1 together with the exhaust filter chamber 260 of the air passage unit 52 and the warm air discharge passage 240.

The drying device 50 is connected to the outer tub 20 through a flexible air inlet duct 54 and an air exhaust duct 55, and the water supply device 60 is connected to the outer tub 20 through a flexible water supply conduit 64. Therefore, when the outer tub 20 is shaken, the intake duct 54, the exhaust duct 55, and the water supply duct 64 absorb the shaking, and the force generated by the shaking is difficult to apply to the warm air generating unit 51, the air duct unit 52, and the filtering of the drying device 50. The unit unit 53 and the water supply unit 61 of the water supply unit 60, the water supply valve 62, and the bath water pump 63.

In the fully automatic washer-dryer 1, the washing operation, the washing and drying operation, or the drying operation of various operation modes are performed. The washing operation is an operation in which only washing is performed, and the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process are sequentially performed. The washing and drying operation is a continuous washing to drying operation, followed by a drying process after the final dewatering process. The drying operation is a drying operation only, and only the drying process is performed.

In the washing process and the rinsing process, the pulsator 26 is rotated to the right and to the left in a state where water is stored in the washing and dewatering tub 24. A flow of water is generated in the washing and dewatering tub 24 by the rotation of the pulsator 26. During the washing process, the laundry is washed by the generated water stream and the detergent contained in the water. During the rinsing process, the laundry is rinsed through the resulting water stream.

The water supply valve 62 is opened during the water supply process of the washing process and the rinsing process. Alternatively, in the case of using bath water, the bath water pump 63 operates. Thereby, tap water or bath water is supplied to the water path 411 of the water supply tank 410. The water supplied to the water path 411 is mixed with the detergent and the softener through the detergent container 420, and reaches the water supply port 412 of the water supply tank 410.

As shown in Fig. 11, in the water supply port 412, the bottom valve 453 is opened by being pushed by the water flow, and the water flowing out from the water discharge port 451 is supplied from the water supply port 22d of the outer tub cover 20b to the outer tub through the water supply pipe 430 and the water supply pipe 64. 20 inside. Here, as shown by the arrow in FIG. 11, a part of the water flowing through the water supply pipe 430 flows through the bottom valve 453. The water flowing through the bottom valve 453 is hard to go to the branch port 431 located on the side of the fixed portion 453a in the water supply pipe 430 on the opposite side to the side of the fixed portion 453a. Therefore, it is difficult for water to penetrate into the branch pipe 440 at the time of water supply. In addition, the water flowing through the side of the fixing portion 453a is also rebounded by the protruding portion 432. From the branch port 431, it is therefore more difficult for water to penetrate into the branch pipe 440. Moreover, even if water penetrates into the branch pipe 440, the water that has penetrated easily returns to the water supply pipe 430 by the inclination of the branch pipe 440.

During the intermediate dewatering process and the final dewatering process, the washing and dewatering tub 24 and the pulsator 26 are integrally rotated at a high speed. The laundry is dehydrated by the action of centrifugal force generated by washing the dewatering tub 24.

In the drying process, the internal air circulation drying process is first performed, followed by the external air introduction drying process. In the internal air circulation drying process, the outside air intake port 231 is closed by the windshield 281 (refer to the solid windshield 281 of FIG. 10), and the outside air is not introduced into the outside air introduction path 230. The blower fan 110 and the heater 120 operate. When the blower fan 110 is operated to rotate the blower 111, as shown in FIG. 4(b), air is sucked from the suction port 103 and wind is generated in the casing 100. The generated wind is heated by the heater 120, and the warm air is discharged from the discharge port 104, and is supplied into the outer tub 20 through the air inlet duct 54.

The warm air supplied into the outer tub 20 flows through the washing and dewatering tub 24. In the washing and dewatering tub 24, the pulsator 26 performs right rotation and left rotation for a fixed time. The laundry in the washing and dewatering tub 24 is in contact with the warm air flowing through the washing and dewatering tub 24 while being stirred by the pulsator 26. As shown in FIG. 10, the warm air flowing through the washing and dewatering tub 24 is discharged from the outer tub 20 through the exhaust duct 55, and is again sucked into the casing 100 from the suction port 103 through the air inlet filter chamber 250 and the air inlet duct 210. Inside.

During the internal air circulation drying process, since the outside air is not taken in, the exhaust air from the warm air in the outer tub 20 is hardly passed through the water supply pipe 64, and the warm air includes the casing 100, the intake duct 210, and The circulation air passage 50a of the intake air filter chamber 250 circulates with the outer tub 20, whereby the temperature inside the washing and dewatering tub 24 rises rapidly.

Foreign matter such as lint coming out of the laundry due to the stirring of the pulsator 26 or the like is mixed into the warm air discharged from the outer tub 20. The warm air passes through the air inlet filter 311 in the air inlet filter chamber 250, and the foreign matter contained in the warm air is collected by the air inlet filter 311.

When the temperature in the washing and dewatering tub 24 continues to rise and the moisture evaporates from the laundry to cause a large amount of moisture in the warm air, the external air is switched to the drying process. The switching to the external air introduction drying process may be performed based on the elapsed time after the start of the drying process, or based on the temperature in the outer tub 20 detected by the temperature sensor, and the inside of the outer tub 20 detected by the humidity sensor. Humidity is carried out.

During the external air introduction and drying process, the wind deflector 281 is opened to allow the external air intake port 231 to be When the outside air is introduced into the outside air introduction path 230, the blower fan 110 and the heater 120 operate in a state where the outside air is introduced into the outside air introduction path 230 (see the broken windshield 281 of FIG. 10). As shown in FIG. 10, the outside air introduced into the outside air introduction path 230 passes through the air inlet filter chamber 250, mixes with the warm air flowing from the exhaust duct 55, and simultaneously flows to the intake duct 210, and is mixed with the outside air. The warm air is drawn into the housing 100. At this time, the outside air passes through the air inlet filter 311 in the air inlet filter chamber 250, and foreign matter such as dust contained in the outside air is collected by the air inlet filter 311.

In the external air introduction and drying process, the ingested outside air increases the flow rate of the warm air supplied into the outer tub 20, so that a part of the warm air containing a large amount of moisture in the outer tub 20 is passed through the water supply path 60a. And the exhaust passage 50b is discharged to the outside of the casing 10. That is, as shown in FIG. 12, a part of the warm air in the outer tub 20 is discharged to the water supply pipe 430 through the water supply pipe 64, and sequentially flows through the branch pipe 440, the exhaust filter chamber 260, and the warm air discharge path 240 from the upper panel. The exhaust hole 12a of 12 is discharged. At this time, the warm air flowing into the water supply pipe 430 is rebounded by the protruding portion 432 that is inclined upward toward the branch port 431, and is guided to the branch port 431 side, thereby facilitating entry into the branch pipe 440 from the branch port 431. Further, since the bottom valve 453 is in a state of blocking the water outlet 451, the warm air in the water supply pipe 430 is prevented from flowing into the water supply tank 410. Further, the warm air discharged to the warm air discharge path 240 passes through the exhaust filter 312 in the exhaust filter chamber 260, and foreign matter such as lint contained in the warm air is collected by the exhaust filter 312.

As described above, by performing the external air introduction drying process, the moisture evaporated from the laundry is efficiently discharged from the inside of the outer tub 20 to the outside of the casing 10, and the inside of the outer tub 20 is easily dehumidified, so that the drying of the laundry can be promoted. It should be noted that a part of the warm air from the outer tub 20 flows through the circulation air passage 50a and is reheated by the heater 120, so that the temperature in the outer tub 20 is maintained at a high state. The drying process ends when the external air is introduced into the drying process.

It should be noted that the air inlet filter chamber 250 and the exhaust filter chamber 260 are separated by the partition plate 350 and the partition frame 270, thereby preventing the warm air flowing through the exhaust passage 50b from leaking into the filter chamber 220 to The circulation air passage 50a side.

The foreign matter is accumulated in the filter material 316 of the air inlet filter 311 and the filter material 319 of the air discharge filter 312 while the washing and drying operation and the drying operation are repeated. When the air inlet filter 311 and the exhaust air filter 312 become blocked by foreign matter, the filter unit 53 is taken out from the filter chamber 220 in order to remove the

filters

311 and 312. Then, the filter body 310 is opened with respect to the filter holder 320, and the filter material 316 of the inlet air filter 311 and the air inlet surface of the filter material 319 of the exhaust filter 312 are cleaned. On the side, the foreign matter attached to the side of the air inlet surface is removed.

(Effect of the present embodiment)

As described above, according to the present embodiment, the water supply pipe 60a, which is a part of the water supply path 60a in the outer tub 20, is connected, and when the outside air is introduced into the drying process, the inside of the outer tub 20 is provided. The warm air is discharged to the outside of the casing 10 through the water supply path 60a and the exhaust passage 50b, so that the water supply pipe 64 of the water supply path 60a serves as a flexible pipe for connecting the exhaust passage 50b and the outer tub 20, and therefore, When the exhaust passage 50b is provided to discharge the warm air in the outer tub 20 to the outside of the casing 10, the number of flexible pipes connected to the outer tub 20 can be suppressed from increasing. Thereby, it is possible to prevent the inner insertion opening 22a formed in the outer tub cover 20b from becoming small, and it is also possible to prevent the balance of the outer tub 20 from being deteriorated by being pulled by the ducts, and the vibration of the outer tub 20 at the time of dehydration becomes large.

In particular, the fully automatic washer-dryer 1 of the present embodiment can discharge a part of the warm air in the outer tub 20 to the outside of the casing 10 while circulating warm air between the circulation air passage 50a and the outer tub 20. The structure of the circulation air passage 50a and the outer tub 20 is provided with two ducts of the air inlet duct 54 and the exhaust duct 55, and therefore, in the case where the duct corresponding to the exhaust duct 50b is correspondingly added, The water supply pipe 64 has a total of four pipes connected to the outer tub 20. In such a case, the inner insertion port 22a is more likely to be smaller, and the vibration of the outer tub 20 at the time of dehydration is more likely to become larger. In the present embodiment, the structure in which the three ducts of the air inlet duct 54, the exhaust duct 55, and the water supply duct 64 are connected to the outer tub 20 can avoid the addition of the duct corresponding to the exhaust duct 50b, thereby preventing the inner side input. The effect of the small opening 22a and the effect of preventing the vibration of the outer tub 20 from becoming large during dehydration are more remarkable.

Further, according to the present embodiment, the bottom valve 453 is provided on the upstream side of the water flow of the branch port 431, and the bottom valve 453 is opened when water is supplied into the outer tub 20, and is closed when the warm air from the outer tub 20 is exhausted. Therefore, when the outside air is introduced into the drying process, the warm air flowing into the water supply pipe 430 from the outer tub 20 is prevented from infiltrating into the water supply tank 410. Thereby, the inside of the water supply tank 410 is warmed by the warm air, and the detergent etc. which remain in the detergent container 420 are prevented from sticking.

Further, according to the present embodiment, the branch port 431 is formed on the side of the fixing portion 453a of the bottom valve 453. Therefore, when water is supplied to the inside of the tub 20, it is difficult for the water flowing through the bottom valve 453 to go to the branch port 431. Therefore, it is difficult for water to penetrate into the branch pipe 440.

Further, according to the present embodiment, the protruding portion 432 is formed on the upstream side of the water flow of the branch port 431, and the flow The water passing through the fixing portion 453a side of the bottom valve 453 is bounced away from the branch opening 431 by the protruding portion 432, so that it is more difficult for water to penetrate into the branch pipe 440.

Further, according to the present embodiment, the branch pipe 440 constituting the exhaust passage 50b is formed to extend obliquely upward from the water supply pipe 430. Therefore, even if water penetrates into the branch pipe 440 which is the inlet to the exhaust passage 50b, the branch is passed through the branch. With the inclination of the tube 440, the water is also easily returned to the water supply pipe 430. In the present embodiment, the branch pipe 440 is connected to the exhaust filter chamber 260 to prevent water from penetrating into the exhaust filter chamber 260, thereby preventing the exhaust filter 312 from being wetted by water.

(change example)

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications other than the above may be made in the embodiments of the present invention.

For example, the drying device 50 may have a structure in which the exhaust duct 55 and the internal air introduction port 252 are not provided, and the warm air is not circulated with the outer tub 20. In this case, the outside air taken in from the outside air intake port 231 by the operation of the blower fan 110 is heated by the heater 120 to become warm air, and is supplied into the outer tub 20 through the air inlet duct 54. Then, the warm air in contact with the laundry is discharged to the exhaust passage 50b through the water supply conduit 64 and the water supply pipe 430, and is discharged to the outside of the casing 10 through the exhaust passage 50b.

Further, the water supply device 60 may be configured such that the detergent container 420 is not provided in the water supply path 60a, and the water is supplied to the outer tub 20 without mixing the detergent or the softener.

Further, an opening/closing valve other than the bottom valve 453, for example, an electromagnetic valve, may be provided upstream of the branch port 431 in order to open and close the water supply path 60a.

In addition, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical spirit of the claims.
