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

  This type of conventional washing and drying machine will be described with reference to FIG.

  As shown in FIG. 7, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided inside a housing 1 of a conventional washing and drying machine, and vibrations during washing and dehydration are caused by the suspension 2. It is configured to absorb. Inside the water tank 3, a cylindrical and horizontal axis type rotating tank 5 that accommodates a so-called drying object 4 (hereinafter referred to as clothing 4) that is to be washed or dried, such as clothes, is rotatably disposed and driven. The rotating shaft 6a is rotated by the motor 6 and is driven to rotate.

  A plurality of baffles (not shown) for stirring the clothes 4 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. The front side of the water tank 3 and the rotary tank 5 also have similar openings 3 a and 5 b, respectively. 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. The drain port 9 is connected to a drain hose 11 via a drain valve 10 and its tip is led out of the washing / drying machine. Yes.

  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. . 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.

  The operation of the conventional washing and drying machine configured as described above is as follows.

When performing the washing operation, 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 a water supply port (not shown) 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 operates to rotate the rotary tank 5. The cleaning operation is performed. 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 the drainage place outside the washing / drying 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 / rinsing operation is completed as described above, the drying operation is started. In the drying process, while the rotating tub 5 is driven to rotate at a low speed by the drive motor 6 and the clothes 4 are stirred, the air heated by the heater 13 becomes warm air and is blown in the direction of arrow a by the blower 12, It passes through the air supply port 14 and enters the rotary tank 5 in the direction of the arrow b. 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 washing and drying machine through the drain valve 10.

Can be made.

  However, in the configuration of the conventional washing / drying machine, the heat used for drying the clothes 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 reused. It never happened.

  Therefore, a compressor that compresses the refrigerant, a radiator that dissipates the heat of the compressed refrigerant, a throttle means for reducing the pressure of the high-pressure refrigerant, and heat from the surroundings by the reduced-pressure and low-pressure refrigerant. It has been proposed that a heat pump device configured by connecting a depriving heat absorber with a pipe line so as to circulate the refrigerant is provided in the washing / drying machine (see, for example, Patent Document 1).

According to this configuration, moisture can be efficiently dried by condensing moisture evaporated from the clothing onto the heat absorber, and the heat of the warm air containing moisture from the clothing is absorbed by the heat absorber. The heat of the refrigerant that is sent to the compressor via the air and is warmed by the compressor is radiated by the radiator and reheats the warm air, so that the heat can be effectively utilized.

In addition, about the same part as the washing-drying machine in a prior art example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 1 to 4, a cylindrical water tank 3 elastically supported by a plurality of suspensions 2 is provided in the inside of the case 1 of the washing and drying machine in the present embodiment. Vibration is absorbed by the suspension 2.

  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 for taking in and out the garment 4 and a door 7 for opening and closing the opening 1a. The front side of the water tank 3 and the rotary tank 5 also have similar openings 3 a and 5 b, respectively. 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 and a drain hose 11.

The blower 12 constituting the blowing means is provided on the outer peripheral surface of the water tank 3 so as to be located in a corner space formed by the upper surface 1 d of the housing 1 and the water tank 3. The blower 12 communicates with the blower path 20 provided on the back surface of the water tank 3, blows the air entered from the blower path 20 in the direction of the arrow b, and supplies the air into the rotary tank 5 from the air supply port 14. Then, the air passing through the rotary tank 5 and coming out from the exhaust port 16 of the water tank 3 is sucked by the blower 12.

  On the rear surface of the water tank 3, a heat absorber air passage 22 that causes air to flow in the direction of arrow e to a heat absorber 21 that is a heat exchanger that constitutes a heat pump device 40 that will be described later, and a radiator 23 that is also a heat exchanger. A heat radiator air passage 24 for flowing air in the direction of the arrow f is arranged in a curved shape, and the heat absorber air passage 22 and the heat radiator air passage 24 communicate with each other through a circulation duct 25 to dissipate the heat absorber 21 and the heat radiation. The air passing through the vessel 23 flows in a curve. The heat absorber air passage 22, the radiator air passage 24, and the circulation duct 25 are integrally formed and fixed to the back surface of the water tank 3.

  The drying air blown by the blower 12 passes through the air supply port 14 into the rotating tub 5 and passes through the clothing 4 in the rotating tub 5 as shown by an arrow b in FIG. Exits the exhaust port 16, passes through the blower 12, passes through the heat absorber 21 of the heat absorber air passage 22, passes through the circulation duct 25, passes through the radiator 23 of the radiator air passage 24, and returns to the air passage 20, It comes to circulate.

  The heat pump device 40 includes a horizontal compressor 26 that compresses the refrigerant, a radiator 23 that radiates heat of the compressed refrigerant, and a throttle means 27 that includes a throttle valve, a capillary tube, and the like for reducing the pressure of the high-pressure refrigerant. And a heat absorber 21 that draws heat from the surroundings by the reduced pressure and low pressure refrigerant is connected by a pipe 28 so that the refrigerant circulates, and the refrigerant flows and circulates in the direction of the arrow h, and the heat pump Realize the cycle.

  Next, the flow of tap water and washing water will be described with reference to FIG.

  The water supply hose 18 is connected to the radiator 23 via the water supply valve 17, and the tap water supplied from the water supply hose 18 can exchange heat in the radiator 23. Further, the outlet of the radiator 23 is connected to the upper part of the water tank 3 through the two-way valve a29 to supply tap water into the water tank 3.

  Moreover, since the pipe 23 which circulates through the heat pump cycle passes through the radiator 23, heat exchange between tap water and the refrigerant can be efficiently performed through the radiation fins 30. Further, there are T-shaped branch paths before and after the two-way valve a29, respectively, and connected to the water storage tank 33 via the two-way valve b31 and the two-way valve c32. Since the outer periphery of the water storage tank 33 is covered with a highly heat-insulating material such as a vacuum heat insulating material, it has high heat retention performance.

  A circulation pump 34 is provided at the lower part of the water tank 3, and the washing water is sucked from the lower part of the water tank 3 and supplied to the radiator 23 through the circulation water path 36, the two-way valve d 35 and the T-shaped branch path. A cleaning water circulation means 41 for circulating the cleaning water is provided. The cross-sectional area of the circulation water channel 36 is set to be larger than the cross-sectional area of the refrigerant pipe 28, and the circulation amount of the washing water is increased by keeping the water flow resistance small, so that lint (lint waste) ) Is difficult to accumulate.

  Further, main components constituting the heat pump cycle such as the compressor 26, the heat absorber 21, and the radiator 23 are installed on the outer peripheral surface of the water tank 3.

  The operation of the washing / drying machine configured as described above will be described.

  In the cleaning process, water is supplied until the water level reaches a predetermined level in the water tank 3 with the drain valve 10 closed, and the drive motor 6 rotates the clothes 4 and the rotating tank 5 containing the cleaning water to perform cleaning.

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 out of the washing and drying machine, and then the rotating tub 5 containing the clothes 4 is rotated at high speed by the drive motor 6 to dehydrate.

  In the drying process, when the compressor 26 of the heat pump device 40 is operated, the refrigerant is compressed, and this pressure circulates through the radiator 23, the throttle means 27, and the heat absorber 21. In the radiator 23, heat is released by the compression of the refrigerant, and in the heat absorber 21, the heat is absorbed by the refrigerant which has been decompressed by the throttle means 27 and becomes a low pressure. At this time, the blower 12 is activated, and warm air heated by heat radiation of the radiator 23 and the compressor 26 passes through the blower passage 20 and is blown into the rotary tank 5 from the air supply port 14. The rotating tub 5 is rotationally driven by a drive motor 6 and the clothes 4 are stirred up and down.

  The warm air blown into the rotating tub 5 deprives moisture when passing through the gap between the clothes 4, passes through the blower 12 through the exhaust port 16 of the water tub 3 in the wet state, and reaches the heat absorber air passage 22. When the wet warm air passes through the heat absorber 21, sensible heat and latent heat are removed, and the dehumidified air is separated into dry air and condensed water. The dry air enters the radiator air passage 24 through the circulation duct 25, is heated again by the radiator 23, becomes warm air, and circulates to the air passage 20.

  In addition to the above basic washing and drying process, an example of a control pattern relating to hot water supply and washing water circulation will be described below with reference to FIGS.

  In the “initial stage” of the washing mode, the tap water supplied from the water supply valve 17 efficiently exchanges heat with the high-temperature and high-pressure refrigerant of the heat pump cycle by the radiator 23 to transfer heat into the water tank 3. Supplied. Further, since the air in the air passage is also heated by the radiator 23, the temperature of the clothing 4 and the washing water can be raised by bringing the warm air into contact with the clothing 4 and the washing water. After a certain amount of hot water is supplied, the operation proceeds to “intermediate to end” of the washing mode, and the wash water in the water tank 3 is sucked from the lower part of the water tank 3 by the circulation pump 34 and supplied to the radiator 23 through the circulation water channel 36. Then, heat is received and supplied into the water tank 3.

  As described above, by controlling the operation of the heat pump cycle, the temperature of the washing water can be kept high and constant, so that a high washing ability can be maintained, and washing can be completed in a short time. Note that this mode operates in the same manner in the rinsing step, and a high rinsing capability can be obtained, so that rinsing can be completed in a short time.

  The water storage mode in which tap water or washing water is stored in the water storage tank 33 is mainly operated particularly in the initial stage of the washing mode. After the amount of hot water necessary for washing is supplied to the water tank 3, the two-way valve a29 is closed and the two-way valve b31 and the two-way valve c32 are opened, whereby hot water is stored in the water tank 33. The stored warm water can be supplied to the water tank 3 at the beginning of the rinsing mode, which is the next step, for example, so that the rinsing ability is improved and the rinsing time is shortened.

  Furthermore, since it has the water storage tank 33 which is covered with a high heat insulating material and has excellent heat retention performance, it is possible to supply hot water having a high temperature, so that the rinsing ability can be further improved and the rinsing time can be shortened.

  In the dry mode, the pressure and temperature of the refrigerant in the radiator 23 are kept within the use limit values by controlling the opening of the water supply valve 17 and the two-way valve a29 and adjusting the amount of water when the heat pump device 40 is in operation. Since a motor (not shown) for driving the compressor 26 can be continuously used, the heat pump device 40 can be efficiently operated while maintaining high reliability, and high drying performance can be obtained.

In addition, since the heat absorber 21, the radiator 23, and the compressor 26, which are the main components constituting the heat pump device 40, are installed directly on the outer peripheral surface of the water tank 3 in the same vibration system, the water tank 3 and the radiator 23.
In addition, since the pipe length between the compressors 26 can be configured to be short and excellent in heat insulation, high-temperature hot water can be supplied, and a washing and drying machine excellent in washing and rinsing performance and reliability can be provided.

  Further, since the air path can be shortened and the ventilation resistance is reduced, the air volume can be improved, so that the drying efficiency is improved, and the blower 12, the heat absorber 21, and the radiator 23 can be installed on the upper part of the water tank 3, so that washing is performed. Since it is possible to prevent intrusion of bubbles and washing water therein, it is possible to provide a washing and drying machine excellent in the reliability durability of the heat absorber 21 and the radiator 23 and the drainage of condensed water.

  Moreover, in this Embodiment, although it has the opening part 1a which puts in / out the clothing 4 in the surface opposite to the surface of the water tank 3 which has the drive motor 6 of the rotation tank 5, an opening part is not limited to the said place, but a water tank 3 and the rotary tank 5 may be set at any position.

  In this embodiment, a drum-type washing / drying machine has been described as an example. However, the drum-type washing / drying machine may be used for a pulsator-type vertical washing / drying machine. Further, the refrigerant used in the heat pump device 40 is not limited to the chlorofluorocarbon system, and natural refrigerant such as carbon dioxide, isobutane, and propane may be used. In this embodiment, the horizontal compressor 26 is used, but a vertical compressor may be used.

As described above, the washing and drying machine according to the present invention, the hot water and hot air by the heat pump device even washing step and the rinsing step is not limited to the drying step is efficiently supplied to the water tank, by further circulating the wash water The temperature of clothes and washing water can be kept high and constant, and it can be applied to various types of washing and drying machines for home use, commercial use, and industrial use.
