The water tank unit 10 has a water tank 3, a rotatable rotary drum 5 supported by a bearing 16 in the water tank 3, and a drum drive motor 4 for driving the rotary shaft 17 of the rotary drum 5 to rotate. In the water tank unit 10, the 'rotation shaft 17' is inclined upward toward the front side (left side), and is supported by the washing machine casing 2 by a suspension structure (not shown). The water tank 3 and the rotating cylinder 5 have openings on the front side, respectively. By opening the door body 8, the laundry can be taken in and out of the opening 6 of the rotary drum 5. When the door body 8 is closed, the bellows 12 is in close contact with the inner surface of the door body 8. The inside of the water tank 3 becomes a watertight and airtight space, and water or air does not leak to the outside in the washing step and the drying step. The heat pump unit 20 is disposed so as to be housed in a space on the back side of the inclined water tank unit 10. The heat pump unit 20 constructed in a compact manner can be configured in such a manner that the size of the washing machine housing 2 is not increased. Fig. 2 is a view showing the structure of the heat pump unit 20 by disassembling the unit casing 21 (Fig. 3). A compressor 27, a heat absorber 28, and a radiator 29 are mounted in the bottom portion 22 of the unit casing. The bottom case 22 is fitted to the upper case 23 by the screw 43 and fitted to the upper case 23. The flow path cover 24 is attached to the rear opening portion of the upper case 23 by the screw 46, and a heated air can be sent to the exhaust connection pipe 33 via the connection cylinder 31a (see Figs. 1 and 3). According to the above configuration, by closing the open portion of the rear surface of the upper case 23, the flow path cover 24 can be extended in the vertical direction in a relatively wide space, and a screw stop portion can be provided in the lower portion of the heated air supply path 45, and The heated air supply air passage 45 having a small space can also form a substantially flat surface in the front and rear directions. As shown in FIGS. 2 and 3, the intake connecting pipe 32 is connected to the moisture-absorbing air intake port 3 of the upper casing 23, and the exhaust connecting pipe 33 is connected to the heated air exhaust passage 45 via the heated air supply passage 45. The port 31 is connected to the cartridge Ma, whereby the heat pump unit 20 is formed. Further, as shown in Fig. 3, a water storage portion 34 for holding the dew condensation water dripped by the heat absorber 28 is formed on the bottom surface of the bottom case 22. The water dropped on the water storage portion 34 passes through the filter 35 to filter the dust, and is discharged from the drain port 36 by a drain pump not shown every predetermined time. The heat absorber 28 and the heat sink 29 are in a state of being inclined to each other, and one of the sides has a predetermined interval opposing surface. The heat absorber 28 is disposed in a direction slightly parallel to the front portion of the upper case 23. The rear wall 23b of the upper case 23 is formed in a substantially vertical direction. An intake space 38 is formed between the other surface of the heat sink 28 and the front wall 23a, and an exhaust space 39 is formed between the other surface of the heat sink 29 and the rear wall 23b. The heat absorber 28 and the heat sink 29 are housed in the unit casing 21 as heat absorbing and heat radiating units 4, and both ends thereof are held by a pair of side wall plates 37, forming a through air absorbing space 38, a heat sink 28, and heat dissipation. The air flow path of the device 29 and the exhaust space 39. Since the heat absorbing and dissipating unit 40 is integrated, the heat absorbing and dissipating unit 40 can be easily incorporated into the unit casing 21 or detached. Thus, the front wall 23a of the upper case 23 is inclined so as not to interfere with the water tank unit 1〇, and the rear wall 23b of the upper case 23 is formed in a substantially vertical direction along the rear surface of the washing machine housing 2, whereby the heat pump unit 20 can be disposed in the water tank unit. 1 〇 1313574 limited space behind. As shown in FIG. 3, the suction space 38 is connected to the moisture absorption air inlet port, and the exhaust space 39 is connected to the heating air exhaust port 3, and the suction air connection pipe is connected to the moisture absorption air inlet port 30, The exhaust connecting pipe 33 is connected to the heated air row 5 port 3 to constitute the hot fruit unit 2〇. Further, as shown in Fig. 2, the refrigerant line 41 penetrating the heat absorber 28 and the radiator 29 is connected to the compressor 27, and as shown in Fig. 4, constitutes a heat pump cycle. The younger brother shows the air supply path between the heat pump unit 20 and the water tank unit 10. An intake port 12 is formed on the back surface and the side peripheral surface of the water tank 3, respectively. Between the intake air σ11 and the exhaust connection buckle, the air supply air supply buckle is connected by the air suction duct 14 having the blow fan 15 to the exhaust port 2 and the connecting tube 32 to form air for drying air. In the step, the water _ free ^ roller 5 has a plurality of through holes 9 on the side peripheral surface, so that water and air can be Z between the rotating drum and the water tank 3, and since the bottom surface has a majority of working holes such as working holes 26 m Therefore, the heat pump unit 20 is rotated by the heated air supply duct 13: the dry heated air is as shown by the arrow, and can be accessed by the suction port u, such as the arrowhead = the moisture in the drum 5 is absorbed by the moisture in the drum 5 ϋ, the through hole 9 and the sulphide inlet and outlet 6 enter the water tank 3, and the front 12 fine wet air supply air f14 is discharged toward the suction connection pipe 32. 兹, 奋 Γ Γ 叙 洗衣 laundry dryer 1 shot open The n body 8 puts the laundry into the rotary shovel 5, and the Shitu-3 inner lining "the water supply pipe of the figure does not supply the water and the detergent to the sink. Wash; strip. The drum drive motor 4 drives the rotary drum 5 to rotate. The agitating blades 7 disposed at a plurality of places in the rotary drum 5 repeatedly bring the laundry to the upper side, so that The washing is carried out by dropping from above, and after the washing step, the washing step and the dehydrating step are carried out, and the washing step can be arbitrarily entered. Further, only the drying step of drying the wetted clothes can be carried out. The operation of the drying step will be described with reference to Fig. 1 to Fig. 4. The heat pump 2 释 can release the heat of the refrigerant whose temperature has risen after being compressed, to the air by the radiator 29, and deliver the refrigerant which has been depressurized by the throttle device 42. The heat absorber 28 absorbs heat from the air. The rotary drum 5 rotates at a speed corresponding to the drying step, and agitates the laundry stored therein. At the same time, the heat pump unit 2 and the blower fan 15 start the cycle of starting the drying air. The air heated by the radiator 29 passes through the exhaust space 39, the exhaust connection pipe 33, and the heated air supply pipe 13, and is sent to the rotary drum 5 by the intake port 12. The heated air absorbs the moisture of the laundry to become the air, The exhaust port 12 is exhausted toward the moisture-absorbing air supply duct 14. The moisture-absorbing air supplied to the moisture-absorbing air supply duct 14 enters the heat pump unit 20 via the intake connecting pipe 32 and the moisture-absorbing air intake port 30. The air space 38 is cooled and dehumidified when passing through the heat absorber 28. The dew condensation water generated during dehumidification is dripped on the water storage portion 34. The air after the dehumidification drying is heated by the radiator 29 and circulated again, and stored in the water storage portion 34. The water is discharged into the water tank 3 by a drain pump (not shown), and is drained to the outside by the drain pump 19 and the drain line 25. The above-described clothes drying device that heats and dehumidifies the drying air by the heat pump unit 20 is recovered by the refrigerant. The heat is absorbed by the heat absorber 28, and then dissipated by the heat sink 29 again. Therefore, the heat of the clothes can be supplied to exceed the energy input to the compressor 28, thereby shortening and saving energy. According to the present invention, it can be limited.
