FIG. 5 is a cross-sectional view taken along the line BB of FIG. 2, and FIG.

  As shown in FIGS. 1 to 5, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided inside the housing 1, and vibrations during washing and dehydration are absorbed by the suspension 2. Inside the water tank 3, a cylindrical and horizontal axis type rotating tank 5 that accommodates the clothes 4 is rotatably provided, and the rotating tank 5 is rotationally driven by the 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.

  The blower 12 forming the blowing means is provided on the outer peripheral surface of the water tank 3 so as to be positioned in a corner space formed by the upper surface 1 d of the housing 1 and the water tank 3. Similarly to the heat sink air passage 22 that is a part of the heat exchange air passage for flowing air in the direction of the arrow e to the heat absorber 21 including the heat exchanger constituting the heat pump device at the lower back of the housing 1. A heat exchanger air passage 24 that is a part of a heat exchange air passage that allows air to flow in the direction of the arrow f is arranged side by side so that each heat exchanger has a substantially letter C shape. It is installed. For this reason, the heat absorber air passage 22 and the radiator air passage 24 are communicated with each other through a circulation duct 25, and the air passing through the heat absorber 21 and the heat radiator 23 efficiently flows in a substantially U shape. Further, since the heat absorber air passage 22, the heat radiator air passage 24, and the circulation duct 25 can be configured integrally and compactly, they are fixed to the lower back portion of the housing 1 as a unit.

  The drying air blown by the blower 12 passes through the heat sink 21 of the heat sink air passage 22 through the flexible connecting pipe 19 and passes through the radiator 23 of the radiator air passage 24 through the circulation duct 25. Then, as shown by an arrow b in FIG. 3, after passing through the flexible connecting pipe 19 and the air passage 20 and entering the rotary tank 5 from the air supply port 14 and passing through the clothing 4 in the rotary tank 5, the exhaust port It comes out of 16, returns to the air blower 12, and circulates.

Since the water storage chamber 29 communicates with the drainage pump 35, the drainage hole a30 or The lint and impurities in the liquid that has passed through the drain hole b31 are separated by the filter. Since the liquid that has passed through the filter 34 is sucked and discharged by the drainage pump 35 and discharged from the drainage hose 11, the lint does not pass through the drainage pump 35 and is excellent in reliability and durability.

  Further, the vertical compressor 26 is separated from the heat exchange air passage by the air passage constituting member 36 forming the heat exchange air passage, and a predetermined amount of gap is provided at the upper portion of the vertical compressor 26 by the air passage constituting member 36. Since the support portion 37 is formed, the vertical compressor 26 does not come into contact with bubbles or washing water passing through the heat exchange air passage and is excellent in corrosion resistance. Even if a large excitation force is applied due to external vibration, the vertical compressor 26 and the support portion 37 come into contact with each other, so that the vibration of the vertical compressor 26 is suppressed.
