Description

  The present invention relates to a washing / drying machine that performs washing / dehydration and drying of clothes in the same rotating tank.

  A conventional drum-type washing and drying machine has a configuration as shown in FIG. Hereinafter, the configuration will be described. As shown in the drawing, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided inside the housing 1 so that vibrations during washing and dehydration are absorbed by the suspension 2. Inside the water tank 3, a cylindrical, horizontal axis type rotating tank 5 that accommodates an object 4 to be washed or dried (hereinafter referred to as clothing) is rotatably arranged, and a rotating shaft 6 a is rotated by a drive motor 6. To rotate.

  A plurality of baffles (not shown) for stirring clothes are provided on the inner wall of the rotating tub 5, and a plurality of small holes 5 a are provided on the peripheral wall of the rotating tub 5. On the front surface of the housing 1, there are provided an opening 1a through which clothes 4 are taken in and out and a door 7 for opening and closing the opening 1a. Similar openings 3 a and 5 b are also provided on the front side of the water tank 3 and the rotating tank 5, and the opening 3 a of the water tank 3 is water-tightly connected to the opening 1 a of the housing 1 by a bellows 8. The bottom of the aquarium 3 has a drain port 9 for discharging washing water, and is connected to a drain hose 11 via a drain valve 10, and its tip is led out of the machine.

  The blower 12 blows and supplies the warm air heated by the heater 13 from the air supply port 14 into the rotary tank 5. The circulation duct 15 dehumidifies the drying air that has passed through the rotary tank 5 and the water tank 3, and has one end connected to the exhaust port 16 at the bottom of the water tank 3 and the other end connected to the blower 12. Yes. The water supply valve 17 controls water supply from a water supply hose 18 connected to a tap or the like of a water supply.

  In the above configuration, when the washing operation is performed, the door 7 is opened, the clothes 4 and the detergent are put into the rotating tub 5, and the operation is started. First, when the water supply valve 17 opens the water supply port on the washing water side and a predetermined amount of water is supplied into the water tank 3 and the rotary tank 5, the drive motor 6 is activated and the rotary tank 5 is rotationally driven to perform a washing operation. . After a predetermined time, the drive motor 6 is stopped, the drain valve 10 is opened, and dirty water is drained from the rotary tank 5 and the water tank 3 and drained to a drainage place outside the machine via the drain hose 11. Next, water is supplied to the water tank 3 and the rotary tank 5 in the same manner as described above, and a rinsing operation is performed. When the rinsing is completed, the drain valve 10 is opened and drained, and then the rotating tub 5 is rotationally driven by the drive motor 6 at a high speed, whereby the clothes 4 are dehydrated.

  When the washing operation is completed as described above, the drying operation is started. In the drying process, the garment 4 is agitated by rotating the rotary tub 5 at a low speed by the drive motor 6. The air blown in the direction of the arrow 19 by the blower 12 is heated by the heater 13 to become warm air, and is sent into the rotary tank 5 from the air supply port 14. This hot air takes away moisture from the garment 4, then passes through the water tank 3 through the small hole 5 a of the rotating tub 5 and reaches the circulation duct 15 through the exhaust port 16.

  At this time, the water supply valve 17 opens the water supply port on the cooling water side, and cooling water is poured into the circulation duct 15. When the warm air containing moisture from the clothing 4 deprives moisture and passes through the circulation duct 15, the cooling water cools it to cause moisture condensation, and the moist warm air is dehumidified and again as shown by the arrow. Return to the blower 12. This cooling water and dew condensation water is drained out of the machine via the drain valve 10. The hot air is circulated through the circulation path from the blower 12 to the heater 13, the air supply port 14, the rotary tank 5, the water tank 3, the exhaust port 16, and the circulation duct 15, thereby drying the clothes 4 in the rotary tank 5. be able to.

  In the above-described conventional configuration, the heat used for drying the garment 4 is all discarded to the outside by the cooling water of the circulation duct 15 or the heat radiation from the housing 1, and is not reused.

Therefore, a compressor that compresses the refrigerant, a radiator that dissipates the heat of the compressed refrigerant, throttle means for reducing the pressure of the high-pressure refrigerant, and the reduced-pressure and low-pressure refrigerant generate heat from the surroundings. It has been proposed to provide a clothes dryer with a heat pump device that is connected to a heat absorber to be taken away by a pipe line so that the refrigerant circulates (see, for example, Patent Document 1). According to this configuration, it has been found that the amount of heat released to the outside can be recovered and the clothes can be effectively dried using energy.
JP 7-178289 A

  However, as described above, the heat pump device circulates the high-pressure refrigerant by connecting the compressor, the radiator, the throttle means, and the heat absorber with a pipe such as a copper tube. There is a possibility that the connection part of the pipe line is loosened due to the influence, or the pipe line resonates to cause fatigue failure. Unlike a single-function clothes dryer, the washing and drying machine has a dehydration process with large vibration that rotates the rotating tub at a high speed. Further, in the case of the drum type washing and drying machine described above, it is a horizontal axis type. Compared with the vertical washer-dryer, the rotational vibration of the rotating tub was larger, and countermeasures against this vibration were indispensable. Furthermore, since the heat pump device connects the compressor, the radiator, the throttle means, and the heat absorber with a pipe line such as a copper tube, it is not easy to assemble at the time of manufacture, and repair maintenance of the heat pump device is not easy.

  The present invention solves the above-described conventional problems, and the heat pump device is less affected by the vibration of the rotating tub and realizes a washing and drying machine excellent in reliability and durability, and is assembled and repaired at the time of manufacture. The purpose is to facilitate maintenance.

The air supply hose and the exhaust hose are made of a flexible cylindrical member. The heat pump device is configured to be detachable from the housing together with the mounting base.

  As a result, even if the water tank vibrates due to the rotational vibration of the rotating tank, the air supply hose and the exhaust hose made of a flexible tubular member bend to absorb the vibration of the water tank, and to the heat pump device. Since vibration is not transmitted directly, the pipe of the heat pump device does not resonate and fail even in the dehydration process where the water tank vibrates greatly. In addition, since the air supply hose and the exhaust hose are detachably provided, and the heat pump device can be pulled out from the housing together with the mounting base, the heat pump device can be separated from the water tank. As a result, the assembly can be facilitated and the repair maintenance of the heat pump apparatus can be facilitated.

  The seventh invention is particularly formed by tilting the first water tank to the front high level, and by tilting the water tank to the front high level with respect to the horizontal, the opening of the water tank and the rotating tank in the water tank is directed upward. In the direction and the drum type washing and drying machine, clothes can be easily taken in and out.

Inside the water tank 3, a cylindrical and horizontal axis type rotating tank 5 that accommodates the clothing 4 is rotatably provided and is driven to rotate by a drive motor 6. On the front surface of the housing 1, there are provided an opening 1a through which clothes 4 are taken in and out and a door 7 for opening and closing the opening 1a. Similar openings 3 a and 5 b are also provided on the front side of the water tank 3 and the rotating tank 5, and the opening 3 a of the water tank 3 is water-tightly connected to the opening 1 a of the housing 1 by a bellows 8. The bottom of the water tank 3 has a drain port 9 for discharging washing water, and is connected to a drain valve 10.

  The blower 12 constituting the blowing means is provided on the upper part of the water tank 3 so as to be positioned in a corner space formed by the upper surface 1c and the side surface 1d of the housing 1. The blower 12 communicates with an air supply duct 20 provided on the outer surface of the water tank 3, and blows air in the direction of arrow c from the air supply duct inlet 21 of the air supply duct 20 to the inside of the rotary tank 5 from the air supply port 14. To supply. Further, an exhaust duct 22 communicating with the exhaust port 16 on the back surface of the water tank 3 is provided on the outer surface of the water tank 3, and the air that has passed through the rotary tank 5 and the water tank 3 and has exited the exhaust port 16 is indicated by an arrow d. To the exhaust duct outlet 23.

  In the lower part of the water tank 3, a heat absorber air passage 31 for flowing air in the direction of arrow a to a heat absorber 30 comprising a heat exchanger constituting the heat pump device, and a heat radiator 32 similarly comprising a heat exchanger indicated by arrow b A radiator air passage 33 for flowing air in a direction is arranged in a horizontal direction, and the heat absorber air passage 31 and the radiator air passage 33 communicate with each other through a circulation duct 34 and pass through the heat absorber 30 and the radiator 32. The air that flows is designed to flow linearly.

  The heat absorber air passage 31, the radiator air passage 33, and the circulation duct 34 are integrally formed and are fixed to an attachment base 35 in the housing 1. The inlet of the heat absorber air passage 31 and the exhaust duct outlet 23 communicate with each other via an exhaust port hose 36 made of a bellows-like stretchable flexible material. Similarly, the outlet of the radiator air passage 33 and the air supply duct inlet 21 communicate with each other via an air supply hose 37 made of a bellows-like stretchable flexible material. In addition, an air filter 38 made of a synthetic fiber net or the like is detachably provided as a filter means for removing foreign substances in the air at the inlet provided upstream of the heat absorber air passage 31. Further, a discharge port 39 for discharging the dehumidified water is provided in the lower part on the downstream side of the heat absorber air passage 31.

  After the drying air blown by the blower 12 passes through the air supply duct 20 and enters the rotary tank 5 through the air supply port 14 and passes through the clothing 4 in the rotary tank 5, as indicated by an arrow 40 in FIG. 4. , Exits the exhaust port 16, passes through the exhaust duct 22, passes through the heat absorber 30 of the heat absorber air passage 31, passes through the circulation duct 34, passes through the radiator 32 of the radiator air passage 33, and returns to the blower 12. It is supposed to circulate.

  The heat pump device also includes a compressor 41, a radiator 32 that radiates the heat of the refrigerant compressed by the compressor 41, and a throttle means 42 that includes a throttle valve, a capillary tube, and the like for reducing the pressure of the high-pressure refrigerant. In addition, the refrigerant having a reduced pressure and a low pressure is connected by a pipe line 43 so that the refrigerant circulates through the heat absorber 30 that takes heat from the surroundings, and the refrigerant flows and circulates in the direction of the arrow 44, and the heat pump cycle. To realize.

  The operation and action of the washing / drying machine configured as described above will be described below. In the washing process, water is supplied until the water level reaches a predetermined water level in the water tank 3 with the drain valve 10 closed, and washing is performed by rotating the clothes tank 4 and the rotary tank 5 containing the washing water by the drive motor 6. At this time, a part of the cleaning water enters the exhaust duct 22, but the exhaust duct 22 has a shape in which the path is lifted upward so that the cleaning water does not enter the heat absorber 30.

  Further, in the rinsing process after washing, water is supplied into the water tank 3 as in the washing process, and the garment 4 is rinsed by rotating the rotating tank 5. In the dehydration step, the drain valve 10 is opened to drain water to the outside of the machine, and then the rotating tub 5 containing the clothing 4 is rotated at high speed by the drive motor 6 to dehydrate.

  During the washing and dehydration, the vibration of the water tank 3 is caused by the rotational vibration of the rotating tank 5. This vibration is absorbed by the suspension 2 and the vibration of the housing 1 is suppressed. Since the heat pump device is fixed to the mounting base 35, it is not affected by vibration from the housing 1. Further, the connection between the inlet of the heat absorber air passage 31 and the exhaust duct outlet 23 and the connection between the outlet of the heat radiator air passage 33 and the air supply duct inlet 21 are exhaust gas made of a flexible cylindrical member, respectively. Since the mouth hose 36 and the air inlet hose 37 are configured to be extendable and contractible, the vibration of the water tank 3 is not directly transmitted to the heat pump device, and the connection portion of the pipe line 43 of the heat pump device is affected by this vibration. It does not loosen and the pipe 43 does not resonate and cause fatigue failure. In addition, since the exhaust hose 36 and the air supply hose 37 are arranged on the lower surface of the water tank 3 and are led out in the same direction and in parallel, the exhaust hose 36 and the air supply hose 37 itself. Since the vibration loads applied to are substantially the same, they can be constituted by a flexible cylindrical member having the same shape and material.

  In the drying process, when the compressor 41 of the heat pump device is operated, the refrigerant is compressed and circulates through the radiator 31, the throttle means 42, and the heat absorber 30 by this pressure. In the radiator 32, heat is released by the compression of the refrigerant, and in the heat absorber 30, the heat is absorbed by the refrigerant that has been depressurized by the throttle means 42 to become a low pressure. At this time, the blower 12 is activated, and the warm air heated by the heat radiation of the radiator 32 is blown into the rotary tank 5 through the supply duct 20 from the supply port 14. The rotating tub 5 is rotationally driven by a driving motor 6, and the clothes 4 are lifted and dropped by the rotation of the rotating tub 5 and are stirred up and down.

  The warm air blown into the rotary tub 5 takes moisture when passing through the gaps of the clothing 4 and passes through the exhaust duct 22 and the exhaust port hose 36 through the exhaust port 16 of the water tub 3 in the wet state, The foreign matter such as lint is removed through 38 and reaches the heat absorber air passage 31. When the wet warm air passes through the heat absorber 30, sensible heat and latent heat are taken away and dehumidified, and separated into dry air and dehumidified water. This dry air enters the radiator air passage 33 through the circulation duct 34, is heated again by the radiator 32, becomes warm air, passes through the air supply hose 37, the air supply duct 20, and circulates to the blower 12. To do.

  On the other hand, the dehumidified water dewed by the heat absorber 30 is discharged out of the machine from the bottom discharge port 39. By using the heat pump device in this way, the heat absorbed by the heat absorber 30 can be recovered by the refrigerant and radiated again by the heat radiator 32 to give the garment 4 more heat than the energy input to the compressor 41. Therefore, it becomes possible to shorten the drying time and realize energy saving.

  As described above, the heat pump device is disposed below the water tank 3 and connected to the air supply hose 37 and the exhaust hose 36 made of a flexible cylindrical member disposed on the lower surface side of the water tank 3. Thus, the position of the opening 1a on the front surface of the main body can be increased so that the clothes 4 can be easily taken in and out, and the lengths of the air supply hose and the exhaust hose can be shortened. In addition, the heat pump device, the air supply hose 37, and the exhaust hose 36 are less susceptible to the vibration of the water tank 3, and the reliability and durability can be improved.

  In the present embodiment, the air supply hose 37 and the exhaust hose 36 are arranged side by side on the left and right sides of the lower surface of the water tank 3, but may be arranged side by side depending on the layout of the heat pump device. .

(Embodiment 2)
5 to 8 show a washing / drying machine according to a second embodiment of the present invention. The same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  A cylindrical water tank 3 elastically supported by a plurality of suspensions 2 inside the housing 1, and a cylindrical, horizontal-axis-type rotatable rotating tank 5 that houses clothes 4 provided in the water tank 3. The heat pump device is configured to connect a drive motor 6 that rotationally drives the rotating tub 5, a heat absorber 30, a heat radiator 32, a compressor 41, and a conduit 43 that circulates a refrigerant. The axis | shaft of the rotation tank 5 inclines 5 to 45 degree | times with respect to the horizontal high front. Accordingly, the water tank 3 is also inclined. In addition, the front surfaces of the housing 1, the water tank 3, and the rotating tub 5 have openings 1a, 3a, and 5a for putting clothes in and out 4 respectively, and the opening 1a of the housing 1 is provided with a door 7 for opening and closing the opening 1a. It has been. The opening 3 a of the water tank 3 is water-tightly connected by the opening 1 a of the housing 1 and the bellows 8 so that water does not leak. The bottom of the water tank 3 has a drain port 9 for discharging washing water, and is connected to a drain valve 10.

  The heat pump device is provided at a lower portion between the water tank 3 formed by tilting the water tank 3 forward and high, and the back surface 1b of the housing 1, and the heat absorber 30 and the radiator 32 are provided on the back surface 1b of the housing 1. Arranged side by side in the parallel direction, the compressor 41 is arranged near the side surface of the casing 1 at the bottom of the water tank 3. The blower 12 constituting the blowing means is disposed between the heat absorber 30 and the radiator 32, that is, in the circulation duct 34, and supplies hot air heated by the radiator 32 into the rotating tub 5.

  The connection between the inlet of the heat absorber air passage 31 and the exhaust duct outlet 23 and the connection between the outlet of the heat radiator air passage 33 and the air supply duct inlet 21 are a flexible bellows made of a flexible cylindrical member. An exhaust hose 36 and an air supply hose 37 constituted by a hose or the like are used. As shown in the figure, by arranging the heat pump device below the rear of the water tank 3 and arranging the exhaust hose 36 and the air supply hose 37 in the same direction on the rear surface side of the water tank 3, the length of the hose can be shortened. The entire body can be configured compactly.

  The exhaust hose 36 and the air supply hose 37 are fixed by a fixture (not shown) such as a hose clip and can be easily attached and detached. Further, the compressor 41, the radiator 32, the heat absorber 30, the duct 43, the heat absorber air path 31, the heat radiator air path 33, the circulation duct 34, and the blower 12 constituting the heat pump device can be pulled out from the housing 1. A fixed mounting base 35 is fixed.

  In the configuration as described above, as in the first embodiment, even if the water tank 3 vibrates due to the rotational vibration of the rotary tank 5, the air tank 3 and the exhaust hose 37 bend to cause the water tank 3 to vibrate. Without being directly transmitted to the apparatus, the connection part of the pipe line 43 of the heat pump apparatus is not loosened due to the influence of the vibration, and the pipe line 43 does not resonate and cause fatigue failure. Further, since the exhaust hose 36 and the air supply hose 37 are led out in the same direction and parallel to the rear surface of the water tank 3, these hoses do not interfere with each other due to the vibration of the water tank 3. Furthermore, since the influence of vibration on these hoses is almost the same, there is a merit that hoses of the same material and shape can be used in design.

  In the present embodiment, as shown in FIG. 7, the mounting base 35 is configured to be slidable rearward of the housing 1. Therefore, since the heat pump device can be separated from the water tank 3 by removing the air supply hose 36 and the exhaust port hose 37 as shown in the figure, the assembly at the time of manufacture becomes easy and the repair maintenance of the heat pump device can be facilitated. it can.

  In particular, when the maintenance of the heat pump device is performed, the air supply port hose 36 and the exhaust port hose 37 are removed on the heat pump device side as shown in the figure so that the surface of the air filter 38 can be directly observed, so that the air filter 38 is clogged. Easy to confirm.

  In addition, when the maintenance of the heat pump device is performed, the air supply hose 36 and the air exhaust hose 37 are removed on the water tank 3 side, so that the air passage in the water tank 3 or the air supply duct 20 can be visually observed. Cleaning maintenance of lint coming out of clothes can be done easily.

  In the above configuration, the connection between the inlet of the heat absorber air passage 31 and the exhaust duct outlet 23 and the connection between the outlet of the radiator air passage 33 and the air supply duct inlet 21 are flexible cylindrical shapes. Although the exhaust port hose 36 and the air supply port hose 37 of the shape which bent the elastic bellows hose which consists of a member at substantially right angle are used, the structure of this part is not limited to this. For example, as shown in FIG. 8A, if the air supply hose 37 is led downward with respect to the rear surface of the water tank 3 and is connected to the outlet of the radiator air passage 33 linearly, The length of the hose 37 can be shortened, and the force in the twisting direction is less likely to act. Further, as shown in FIG. 8B, the air supply hose 37 is led out at a right angle to the rear surface of the water tank 3, and the outlet of the radiator air passage 33 is provided in parallel with the rear surface of the water tank 3. The mouth hose 37 can be connected almost linearly. By doing so, the length of the air supply hose 37 can be shortened as described above, and the twisting force is hardly generated.

(Embodiment 3)
FIG. 9 is a cross-sectional view of the washing / drying machine according to the third embodiment of the present invention as seen from the back side. The same components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

Further, a discharge port 39 for discharging the dehumidified water is provided in the lower part on the downstream side of the heat absorber air passage 31.

  If the heat pump device is arranged in the upper part of the water tank 3, the washing liquid at the time of washing does not enter the heat absorber 30 and the radiator 32 of the heat pump device from the dry air passage. The heat absorber 30 or the heat radiator 32 is usually made of a metal such as copper or aluminum having good heat conductivity, and when components such as a detergent, a softening agent, a bleaching agent, etc. in the washing liquid adhere, they are corroded. Therefore, by not allowing the washing liquid to enter, corrosion of the heat absorber 30 and the radiator 32 can be prevented, and durability and reliability can be improved.

  As described above, the heat pump device is arranged at the upper part of the water tank 3, and the air supply hose 37 and the exhaust hose 36 are arranged on the upper surface side of the water tank 3, so that the lengths of the air supply hose 37 and the exhaust hose 36 are increased.
