  • outer tub 1 is resiliently supported by multiple suspension mechanisms 3 within housing 2.
  • Drum 4 has inlet 6 on the front for loading or unloading clothes 5, shapes like a cylinder having a bottom, and is installed in outer tub 1.
  • Drum 4 rotates on rotary shaft 7, accommodates clothes 5, and is formed of enclosing wall 8 having numerous vents 9.
  • outer tub 1, drum 4 and rotary shaft 7 tilt up toward a front (front-up and rear-down) by angle ⁇ , e.g. 20 degrees, relative to the horizontal.
  • Motor 10 is mounted to the outer face of underside 1b of outer tub 1 for rotating drum 4 forward or backward.
  • Housing 2 includes round inlet 6 on the front for loading or unloading clothes 5, and door 11 for opening or closing inlet 6.
  • Inlet 6 confronts opening 1a of outer tub 1, and opening 1a is air-tightly connected to housing 2 with packing 12.
  • Water inlet 13 is placed at the upper part of outer tub 1 and connected to water supply valve 14 placed above outer tub 1.
  • Outer tub 1 includes drain port 15 at underside 1b for draining wash water, and drain port 15 is connected to drain valve 16.
  • Blower 17, shown in Fig. 1 forms a blowing means, and is placed over outer tub 1 such that blower 17 is located in the space formed between the top face of housing 2 and outer tub 1 at the upper-rear inside of housing 2.
  • Blower 17 communicates with air-supply duct 18 provided on an outer wall of outer tub 1, and blows air supplied from duct port 18a shown in Figs. 2 and 3 along arrow 19 into drum 4 through air inlet 20.
  • Outer tub 1 includes exhaust port 21 at the top face in front, and the air travels through drum 4 and outer tub 1 and then exhausts from exhaust port 21 to the outside of drum 4.
  • bottom face 22a of outer shell 22 of the heat pump tilts along arrow 27 showing the flow of drying air, i.e. bottom face 22a is placed generally in parallel with rotary shaft 7 as outer tub 1 is placed (front-up and rear-down).
  • outer shell 22 has opening 22b at the top face.
  • Outer shell 22 is removable from housing 2 along vertical direction as indicated by the up-down arrows shown in Fig. 9 .
  • Upper inside of housing 2 there are front bracket 44a extending backward and rear bracket 44b extending forward, and they support heat pump 47 within housing 2.
  • heat pump 47 belongs to the same vibration system as housing 2.
  • Heat pump 47 is supported within housing 2 by a supporter formed of front bracket 44a and rear bracket 44b such that a given space can be formed between the underside of outer shell 22 of the heat pump and the top face of outer tub 1. This structure allows preventing outer tub 1 from touching outer shell 22 when tub 1 trembles due to the spin of drum 4.
  • the drying air blown by blower 17 travels through air-supply duct 18, air inlet 20 and goes into drum 4, and passes through clothes 5 in drum 4, then goes out from exhaust port 21 as shown with arrow 28 in Fig. 10 .
  • the drying air then travels through connecting member 23 on heat absorber side, and goes into heat absorber 24, heat radiator 25 placed in outer shell 22 (not shown in Fig. 10 ) of the heat pump, and then travels through connecting member 26 on heat radiator side, and finally returns to blower 17.
  • the drying air thus forms an air-circulation path.
  • heat absorber 24, heat radiator 25 and compressor 29 are unitized into the heat pump and placed on base 30.
  • Base 30 is placed along bottom face 22a of outer shell 22 of the heat pump such that base 30 is removable from outer shell 22 in vertical direction as indicated by up-down arrows 28a shown in Fig. 8 .
  • Base 30 includes first setting section 30a shaped like a plane on which heat radiator 25 and heat absorber 24 are set, and second setting section 30b shaped like a cylinder in which compressor 29 is accommodated.
  • Second setting section 30b is formed behind first setting section 30a, and located deeper backward above drum 4 than first setting section 30a.
  • first setting section 30a tilts along arrow 27 indicating the flow of the drying air, namely, it tilts generally in parallel with the top face of outer tub 1, i.e. front-up and rear-down.
  • First setting section 30a of base 30 includes lower separator 30c and upper separator 30d extending vertically as shown in Fig. 8 .
  • Those separators isolate heat absorber 24 and heat radiator 25, i.e. heat exchanger side, from compressor 29, i.e. compressor side on first setting section 30a.
  • Heat absorber 24 and heat radiator 25 have their lower ends placed on lower separator 30c, and then upper separator 30d fits onto the upper ends of heat absorber 24 and heat radiator 25 so that heat absorber 24 and heat radiator 25 can be fixed to base 30.
  • Discharge port 31 is provided to the lower rear part of outer shell 22 on heat exchanger side for discharging the water dehumidified by heat absorber 24. As shown in Fig. 5 , opening 22b of outer shell 22 is covered with cover 33 unified with lid 32 which opens/closes top opening 2a of housing 2. Outer shell 22 of the heat pump and cover 33 form the air-circulation path through which the drying air travels.
  • Lid 32 can swing relative to housing 2 on hinge mechanism 34 provided to the rear upper end of housing 2, so that it opens/closes top opening 2a of housing 2.
  • cover 33 unified with lid 32 at the inner face of lid 32 opens/closes opening 22b of outer shell 22 of heat pump. In other words, when lid 32 has opening 2a of housing 2 opened, opening 22b of outer shell 22 is opened simultaneously.
  • Connecting member 23 on heat absorber side is coupled to entrance 22e provided to the front side of outer shell 22 under lid 32, and connecting member 26 on heat radiator side is coupled to exit 22f provided to the rear side of outer shell 22 under lid 32. This structure allows detaching the connecting members 23 and 26 from outer shell 22 by opening lid 32.
  • Heat pump 47 includes the following structural elements:
  • the refrigerant of the heat pump flows along arrow 37 and circulates to form a heat pump cycle.
  • Compressor 29 is coupled electrically to controller 38 provided outside heat pump 47, where controller 38 is placed below outer tub 1. Heat pump 47 and controller 38 are detachable from each other via an electric connecting section formed of connector 38a shown in Fig. 10 . Connector 38a is held at a rear corner section over heat pump 47, where the rear corner section is formed between outer shell 22 and lid 32 so that connector 38a can be simply removed from top opening 2a of housing 2 with lid 32 opened.
  • drum-type washing and drying machine of the present invention comprising the following structural elements:
  • Heat pump 47 comprises the following structural elements:
  • Compressor 29, squeezer 35, heat radiator 25, and heat absorber 24 coupled together by pipes 36 are disposed above outer tub 1 so that they can be detachable through top opening 2a of housing 2.
  • the structure discussed above allows eliminating the time and labor necessary for moving/restoring the drum-type washer from/to the work-place in order to repair or give the washer maintenance work.
  • the washer thus can be repaired or undergo the maintenance work with ease.
  • heat pump 47 Since heat pump 47 is placed above outer tub 1, the washing water never enters air-circulation path 22 disposed above drum 4.
  • This structure thus prevents heat absorber 24 and heat radiator 25 made of metal excellent in heat conduction, e.g. copper or aluminum, from being corroded by detergent, softening agent, bleaching agent contained in the wash water.
  • This structure also allows simply draining the water produced by heat absorber 24 during the drying operation without using a draining means such as a pump.
  • Heat pump 47 can be supported by a supporter provided to housing 2 shown in Fig. 1 so that heat pump 47 is located above outer tub 1.
  • housing 2 is equipped with this another supporter for supporting heat pump 47 such that heat pump 47 can be located above outer tub 1.
  • This structure prevents the vibration of outer tub 1 from traveling to heat pump 47 directly, so that adverse affect of vibration of drum 4 during the dehydrating operation can be eliminated.
  • the reliability and durability of heat pump 47 can be thus improved.
  • heat pump 47 can be detached or mounted with ease above outer tub 1 which may swing though because tub 1 is resiliently supported in housing 2.
  • heat pump 47 is formed of compressor 29, heat radiator 25 and heat absorber 24 unified together on base 30, and then base30 is detachably mounted to housing 2 as shown in Fig. 1 .
  • This structure allows fixing the relative positions among compressor 29, squeezer 35, heat radiator 25, and heat absorber 24 coupled together by pipes 36, so that the stress applied to pipes 36 can be reduced.
  • Heat pump 47 can be thus simply handled when it is detached or mounted from/to housing 2, and actually it can be detached or mounted with ease from/to above outer tub 1.
  • drum-type washing and drying machine (hereinafter referred to simply as a drum-type washer) as structured above is demonstrated hereinafter following the order of chief steps of the drum-type washer: washing step, rinsing step, dehydrating step, and drying step.
  • the water is supplied into outer tub 1 as is done in the washing step for rinsing clothes 5 by rotating drum 4.
  • drum 4 spins and vibrates, which produces vibrations on the entire outer tub 1, the vibrations can be absorbed by suspension mechanisms 3, so that the vibrations are attenuated before they reach housing 2, which thus poorly vibrates.
  • compressor 29 of heat pump 47 compresses the refrigerant, and the pressure of compressor 29 allows the refrigerant to circulate in heat radiator 25, squeezer 35 and heat absorber 24 through pipes 36.
  • Heat radiator 25 radiates the heat of the compressed refrigerant, and in heat absorber 24, the refrigerant decompressed by squeezer 35 absorbs heat.
  • blower 17 blows warm air heated by the heat dissipated from heat radiator 25 into drum 4 through air-supply duct 18 and air inlet 20.
  • Drum 4 is driven by motor 10, and clothes 5 are lifted and dropped due to the spin of drum 4, whereby clothes 5 are agitated up and down.
  • the warm air blown into drum 4 travels through respective clothes 5, thereby depriving clothes 5 of water, and the damped warm air travels through exhaust port 21, connecting member 23 on heat absorber side, and reaches heat absorber 24.
  • the air is deprived of sensible heat and latent heat, and dehumidified.
  • the air is separated into dry-air and water.
  • the dry-air is heated again by heat radiator 25 placed immediately after heat absorber 24, and becomes warm before it travels through blower 17 and air-supply duct 18, and reaches drum 4, in other words, the air circulates to drum 4.
  • the water can be discharged from discharge port 31 to the outside directly, or it can be discharged from drain port 15 via outer tub 1 to the outside.
  • heat pump 47 allows the refrigerant to recover the heat which heat absorber 24 absorbs from the ambient air, and then allows the refrigerant to dissipate the heat again in heat radiator 25, so that an amount of heat greater than the energy supplied to compressor 29 can be supplied to clothes 5. As a result, a drying time can be shortened and energy can be saved.
  • inlet 6 is located at a convenient height for a user to load or unload clothes 5, and spaces having an appropriate width, depth and height for placing some devices can be obtained both at the lower front and the upper rear in housing 2.
  • Placement of heat pump 47 above outer tub 1 allows simply taking out compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 coupled together by pipes 36 upward from top opening 2a by opening lid 32 as shown in Fig. 5 .
  • the drum-type washer is placed, in general, in front of wall 39 or between walls 39 with a small space reserved between rear face 2b of housing 2 and wall 39, or between at least one of lateral faces 2c of housing 2 and wall 39 as shown in Fig. 5 .
  • Lid 32 is one of the structural elements contributing to the external appearance of the drum-type washer, and yet, lid 32 is rather easy to open while the time and labor for moving the drum-type washer can be eliminated.
  • This configuration and the placement of heat pump 47 above outer tub 1 allow taking out compressor 29, squeezer 35, heat radiator 25 and heat absorber 24, forming heat pump 47, upward with ease. As a result, the maintenance work on heat pump 47 can be done with more ease.
  • heat pump 47 above outer tub 1 allows preventing the wash water from entering heat absorber 24 or heat radiator 25 of heat pump 47 through circulation path 22.
  • Heat absorber 24 and heat radiator 25 are generally made of metal excellent in heat conduction, e.g. copper or aluminum, and when the components of detergent, softening agent, bleaching agent contained in the wash water attach to heat absorber 24 or heat radiator 25, the components probably corrode heat absorber 24 or heat radiator 25.
  • the placement of heat pump 47 above outer tub 1 thus prevents the wash water in outer tub 1 located below heat pump 47 from attaching to heat pump 47.
  • the structure discussed above thus prevents the wash water from entering heat pump 47, so that heat absorber 24 and heat radiator 25 can be prevented from being corroded without taking any measures against corrosion. As a result, the durability and reliability of heat absorber 24 and heat radiator 25 can be improved.
  • heat absorber 24 can be placed at a comparative upper section among the structural elements of the drum-type washer. This placement allows the water, which is produced by heat absorber 24 in dehumidifying the drying air during the drying step, travels on first setting section 30a tilted up toward a front (front-up and rear-down) as outer tub 1 is tilted, and is discharged from discharge port 31 shown in Fig. 3 or Fig. 6 . As a result, the water can be discharged without using an extra mechanical discharging means.
  • Heat pump 47 is formed of compressor 29, heat radiator 25, heat absorber 24, and those elements are mounted to and unified with base 30 as shown in Fig. 6 and Fig. 8 , and unified base 30 can be mounted to or removed from housing 2.
  • the unit assembly discussed above allows heat pump 47 to be mounted or detached for the repair work or maintenance work free from stress applied to pipes 36, so that the workers do not need to pay much attention to handling pipes 36 of heat pump 47. In other words, this structure eases this burden (handling pipes 36 with great care) for the workers, who can thus work more efficiently.
  • Compressor 29 is placed such that the bottom thereof is kept horizontal, namely, in parallel to the horizontal. This structure allows determining whether or not the relative positional relations among compressor 29, squeezer 35, heat radiator 25, and heat absorber 24 can be maintained in the drum-type washer based on this horizontal status as a reference when those elements are taken out. This determination will reduce the possibility of producing the stress applied to pipes 36 caused by a deviation in the relative positional relations.
  • Second setting section 30b where compressor 29 is placed is located lower than first setting section 30a where heat radiator 25 and heat absorber 24 are placed.
  • the bottom of compressor 29 having a comparative greater weight among the structural elements of heat pump 47 is thus situated at a rather lower location.
  • This structure allows the workers to take out, in a stable manner, compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 unified together. Even if compressor 29 and other elements coupled with pipes 36 touch housing 2 and encounter with waver unexpectedly, they wave but subside soon because the center gravity of the mass is situated at a rather lower place. This structure thus reduces the possibility of applying the stress, produced by a deviation in the relative positional relations, to pipes 36. Heat pump 47 can be thus placed with the bottom of compressor 29 kept parallel to the horizontal.
  • the foregoing structure allows the worker to place compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 coupled by pipes 36 with the bottom of compressor 29 kept parallel to the horizontal when the worker takes out or mounts those elements. As a result, the relative positional relations among those elements can be maintained, and the stress applied to pipes 36 can be reduced.
  • Heat pump 47 includes first setting section 30a on which at least one of heat radiator 25 or heat absorber 24 is mounted and second setting section 30b on which compressor 29 is mounted, and the second setting section 30b is situated lower than first setting section 30a.
  • This structure allows compressor 29, having a greater mass than heat radiator 25 or heat absorber 24, to be located at a lower place than heat radiator 25 and heat absorber 24, so that the center gravity of the mass can be lowered for simpler handling and better operability when those elements are removed or mounted. Even if those elements touch housing 2 and receive external force unexpectedly, they wave but subside soon because of the lowered center gravity of the mass. This structure thus reduces the possibility of applying the stress, produced by a deviation in the relative positional relations, to pipes 36.
  • First setting section 30a is placed at a forward section above drum 4 and second setting section 30b is placed at a backward section above drum 4, so that the worker can take out the heat pump with ease.
  • this structure allows placing the air-circulation path in a compact manner. Since heat radiator 25 and heat absorber 24 placed on first setting section 30a can be divided into two sections, they can be placed in a flexible manner. Taking advantage of this flexible placement, it is desirable for forming a heat transfer mechanism having a maximized heat-transfer area in order to accelerate heat transfer to/from the drying air. Heat radiator 25 and heat absorber 24 thus can be placed in a more flexible manner than compressor 29 placed on second setting section 30b; however a capacity accommodating heat radiator 25 and heat absorber 24 is often obliged to be great.
  • air inlet 20 is placed at the vicinity of the rear face of drum 4, and exhaust port 21 is placed at the vicinity of the front face of drum 4.
  • This structure allows the drying air to circulate from underside 1b, where a large number of clothes 5 exists, of drum 4 toward inlet 6.
  • the drying air thus can stay in drum 4 for a longer time, so that the drying air can be brought into contact with clothes 5 more efficiently, and this structure advantageously uses the drying air to dry clothes 5.
  • the air-circulation path, through which the drying air flows, is formed of outer shell 22 of the heat pump, and this air-circulation path is placed along rotary shaft 7, so that the drying air can flow smooth, and the air-circulation path can be placed in a compact manner.
  • the air-circulation path is placed above drum 4, and is tilted up toward a front (front-up and rear-down), and kept approx. parallel to rotary shaft 7 of drum 4.
  • This structure allows placing the air-circulation path compactly, which allows the worker in charge of the repair or maintenance work to take out heat pump 47 with more ease.
  • heat pump 47 includes air-circulation path 22 formed along rotary shaft 7 of drum 4, and either one of air inlet 20 or exhaust port 21 is placed at the front side of drum 4 and the remainder is placed at the rear side of drum 4.
  • First setting section 30a on which at least one of heat radiator 25 or heat absorber 24 is mounted is placed at the forward section above drum 4
  • second setting section 30b on which compressor 29 is mounted is placed at the backward section above drum 4.
  • first setting section 30a where heat radiator 25 or heat absorber 24 is mounted, is placed on the forward section above drum 4.
  • This structure allows the worker to take out heat pump 47 from housing 2 with ease even if heat pump 47 is upsized by enlarging the heat-exchange area in order to increase efficiency both in dehumidifying and heating.
  • Heat pump 47 though it is upsized, can be placed in the air-circulation path compactly.
  • Air-circulation path 22 is placed above drum 4 and tilted up toward a front (front-up and rear-down) and kept parallel to rotary shaft 7 of drum 4. This structure allows draining the dew water produced by heat absorber 24 from the rear of drum 4 with ease. On top of that air-circulation path 22 runs along outer tub 1 so that path 22 can be placed compactly. The drying air thus can circulate in drum 4 efficiently.
  • the structure discussed above allows taking out heat pump 47 or the structural elements forming pump 47 from housing 2 with ease in the case of repair or maintenance.
  • air-circulation path 22 is formed of connecting member 23 coupled to outer tub 1 on heat absorber side, outer shell 22 having heat absorber 24 and heat radiator 25 therein and covered with cover 33, connecting member 26 on heat radiator side, and air-supply duct 18 coupled to outer tub 1.
  • Connecting members 23, 26 and outer shell 22 are placed above drum 4.
  • Entrance 22e communicates with exit 22f of outer shell 22 under lid 32 as shown in Fig. 7 or Fig. 8 .
  • Entrance 22e of outer shell 22 is formed between connecting member 23 on heat absorber side and the front side of outer shell 22, and exit 22f is formed between connecting member 26 on heat radiator side and the rear side of outer shell 22. This structure allows the connecting members 23 and 26 to be detachable from outer shell 22 by opening lid 32.
  • Air-circulation path 22 formed by outer shell 22 covered with cover 33 is tilted up toward a front (front-up and rear-down) and kept parallel to rotary shaft 7 of drum 4.
  • Path 22 includes opening 22b through which heat radiator 25 and heat absorber 24 can be removed, and cover 33 for covering opening 22b.
  • This structure eliminates the work of a repairman to detach heat pump 47 from the air-circulation path, and the removal off cover 33 allows the repairman to simply take out upsized heat pump 47, in which the structural elements including compressor 29 are connected and unitized together by pipes 36. The repairman can thus repair heat pump 47 efficiently.
  • Cover 33 is unitarily formed with lid 32, so that an open of lid 32 simultaneously opens opening 22b of outer shell 22, thereby exposing heat absorber 24, heat radiator 25 and compressor 29 accommodated in outer shell 22.
  • the air-circulation path includes opening 22b through which heat radiator 25 and heat absorber 24 can be removed, and cover 33 detachably mounted for covering the opening 22b.
  • Heat pump 47 accommodates heat radiator 25 and heat absorber 24 in the air-circulation path, and cover 33 finishes up the air-circulation path.
  • the air-circulation path includes opening 22b on the upper side, and cover 33 detachably mounted for covering the opening 22b, and heat radiator 25 and heat absorber 24 can be removed through opening 22b.
  • Heat pump 47 accommodates heat radiator 25 and heat absorber 24 in the air-circulation path.
  • Cover 33 finishes up the air-circulation path, and is unitarily formed with lid 32. This structure allows saving a worker from taking out the air-circulation path coupled to outer tub 1, and instead, allows the worker to simply take out compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 coupled together by pipes 36 from top opening 2a of housing 2 by just removing cover 33. On top of that, an open of lid 32 simultaneously opens opening 22b of outer shell 22, thereby exposing heat radiator 25 and heat absorber 24 accommodated in the air-circulation path for being detached or mounted.
  • Lid 32 can swing rearward on hinge mechanism 34 so that it can open/close housing 2.
  • the maintenance work for heat pump 47 is done temporarily in front of the space where the drum-type washer is kept, so that the worker should reserve a place for placing lid 32 to be removed. Since this hinge mechanism can hold lid 32 to open/close housing 2, the worker needs not to find the place.
  • Hinge mechanism 34 also couples lid 32 to housing 2, so that a joining work, necessary when lid 32 is closed, between housing 2 and lid 32 can be simplified.
  • Heat pump 47 is electrically connected to controller 38 with a connecting section, i.e. connector 38a, which is placed near to top opening 2a such that connector 38a can be seen when lid 32 is opened as shown in Fig. 1 . This placement allows the worker to simply detach heat pump 47 from connector 38a without any obstacle.
  • a connecting section i.e. connector 38a
  • Outer shell 22 of heat pump is coupled to connecting member 23 on heat absorber side and connecting member 26 on heat radiator side immediately under lid 32 and near top opening 2a, where both of connecting members 23 and 26 are made of flexible material, the flexibility of connecting members 23 and 26 aids the worker in removing heat pump 47 efficiently from outer shell 22.
  • Compressor 29, squeezer 35, heat absorber 24 and heat radiator 25 coupled together by pipes 36 can be detached as a unitized heat pump 47 from above outer tub 1.
  • Lid 32 can swing on hinge mechanism 34, which thus saves the worker from removing lid 32 or reserving a space for temporarily placing lid 32.
  • the worker thus can do the repair work or maintenance work with lid 32 connected to housing 2, so that the worker can open/close top opening 2a of housing 2 with ease.
  • the drum-type washer includes controller 38 for controlling the operation of heat pump 47, and the electric connecting section between controller 38 and heat pump 47 is formed such that heat pump 47 can be removed from controller 38 through top opening 2a.
  • This structure allows the worker to electrically and safely separate heat pump 47 from controller 38 before the worker takes out heat pump 47, and also allows the worker to connect again to controller 38 without fail after the worker mounts heat pump 47 properly.
  • the drum-type washer includes flexible connecting members 23, 26 for coupling heat pump 47 to outer tub 1. First ends of respective connecting members 23, 26 are coupled to the air-circulation path, and second ends thereof are coupled to outer tub 1. At least one of the first or the second ends thereof is removable through top opening 2a of housing 2.
  • the flexibility of connecting members 23 and 26 allows the worker to separate heat pump 47 from outer tub 1 with ease, so that the worker can remove heat pump 47 efficiently.
  • hinge mechanism 34 between lid 32 and housing 2 is placed on the rear side of housing 2; however, it can be placed on the lateral side, i.e. lid can be opened laterally.
  • the drying air is introduced from the rear of drum 4 and exhausted from the front; however, the drying air can flow in a reversal direction.
  • Heat pump 47 can be taken out together with outer shell 22.
  • Fig. 11 shows a sectional view of an essential part of a drum-type washing and drying machine (hereinafter simply referred to as a drum-type washer) in accordance with the comparative example is not part of the present invention.
  • Fig. 12 shows a perspective view of the drum-type washer, where a part of housing 2 is viewed from the top. Similar elements to those used in the first embodiment have the same reference signs, and the descriptions thereof are omitted here.
  • the drum-type washer in accordance with the comparative example differs from the one in accordance with the first embodiment in mounting unitized heat pump 47 detachably above outer tub 1, where compressor 29, squeezer 35, heat absorber 24 and heat radiator 25 are coupled together by pipes 36 and unitized into heat pump 47.
  • outer shell 22 of heat pump is rigidly mounted onto outer tub 1 with detachable brackets 45. Opening 22b of outer shell 22 is covered with cover 46 independent of lid 32, and cover 46 is detachable vertically as indicated by up-down arrow 48 shown in Fig. 12 . An open of lid 32 allows removing cover 46. Heat absorber 24 and heat radiator 25 are placed in the space formed between outer shell 22 and cover 46, thereby forming an air-circulation path through which the drying air circulates.
  • the foregoing structure allows heat pump 47 to be detachably mounted to the top face of outer tub 1, and to belong to the vibration system of outer tub 1.
  • the weight of heat pump 47 is thus added to outer tub 1.
  • this additional weight allows reducing the vibration amplitude.
  • the drum-type washer operates more quietly.
  • Heat pump 47 can be mounted to the top face of outer tub 1 as shown in Fig. 11 . This structure allows constructing heat pump 47 compactly to be accommodated in a limited space formed above outer tub 1 and within housing 2, and the own weight of heat pump 47 thus can reduce the vibrations of outer tub 1.
  • Compressor 29, heat radiator 25, and heat absorber 24 are unitarily mounted on base 30 and unitized into heat pump 47, and base 30 is detachably mounted above outer tub 1 as shown in Fig. 1 .
  • This structure allows fixing the relative positions among compressor 29, squeezer 35, heat radiator 25, and heat absorber 24 coupled together by pipes 36, so that the stress applied to pipes 36 can be reduced.
  • Heat pump 47 can be thus simply handled when it is detached or mounted from/to housing 2, and can be compactly placed in the limited space formed above outer tub 1 and within housing 2.
  • Heat pump 47 can be placed with the bottom of compressor 29 kept parallel to the horizontal. This structure allows a repairman to place compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 coupled by pipes 36 with the bottom of compressor 29 kept parallel to the horizontal when the repairman takes out or mount those elements. As a result, the relative positional relations among those elements can be maintained, and the stress applied to pipes 36 can be reduced.
  • Heat pump 47 includes first setting section 30a on which at least one of heat radiator 25 or heat absorber 24 is mounted and second setting section 30b on which compressor 29 is mounted, and the second setting section 30b is kept lower than first setting section 30a.
  • This structure allows compressor 29, having a greater mass than heat radiator 25 or heat absorber 24, to be located at a lower place than heat radiator 25 and heat absorber 24, so that the center gravity of the mass can be lowered for simpler handling and better operability when those elements are removed or mounted. Even if those elements touch housing 2 and receive external force unexpectedly, they wave but subside soon because of the lowered center gravity of the mass. This structure thus reduces the possibility of applying the stress on pipes 36 caused by a deviation in the relative positional relations among the structural elements including compressor 29.
  • Heat pump 47 includes air-circulation path 22 formed along rotary shaft 7 of drum 4, and either one of air inlet 20 or exhaust port 21 is placed at the front side of drum 4 and the remainder is placed at the rear side of drum 4.
  • First setting section 30a on which at least one of heat radiator 25 or heat absorber 24 is mounted is placed at a forward section above drum 4, and second setting section 30b on which compressor 29 is mounted is placed at a backward section above drum 4.
  • first setting section 30a where heat radiator 25 or heat absorber 24 is mounted, is placed on the forward section above drum 4.
  • This structure allows the repairman to take out heat pump 47 from housing 2 with ease even if heat pump 47 is upsized by enlarging the heat-exchange area in order to increase efficiency both in dehumidifying and heating.
  • Heat pump 47 though it is upsized, can be placed in air-circulation path 22 compactly.
  • Air-circulation path 22 is placed above drum 4 and tilted up toward a front (front-up and rear-down) and kept parallel to rotary shaft 7 of drum 4. This structure allows draining the dew water produced by heat absorber 24 from the rear of drum 4 with ease. On top of that air-circulation path 22 runs along outer tub 1 so that path 22 can be placed compactly. The drying air thus can circulate in drum 4 efficiently.
  • the structure discussed above allows taking out heat pump 47 or the structural elements forming pump 47 from housing 2 with ease in the case of repair or maintenance.
  • the air-circulation path includes opening 22b on the upper side, and cover 46 detachably mounted for covering opening 22b, and heat radiator 25 and heat absorber 24 can be removed through opening 22b.
  • Heat pump 47 accommodates heat radiator 25 and heat absorber 24 in the air-circulation path.
  • Cover 46 finishes up the air-circulation path. This structure allows saving a worker from taking out the air-circulation path coupled to outer tub 1, and instead, allows the worker to simply take out compressor 29, squeezer 35, heat radiator 25 and heat absorber 24 coupled together by pipes 36 from top opening 2a of housing 2 by just removing cover 46.
  • Lid 32 can swing on hinge mechanism 34, which thus saves the worker from removing lid 32 or reserving a space for temporarily placing lid 32.
  • the worker thus can do the repair work or maintenance work with lid 32 connected to housing 2, so that the worker can open/close top opening 2a of housing 2 with ease.
