Description

  The present invention relates to a dehumidifying and warming device that dehumidifies and warms air, and particularly to a compact dehumidifying and warming device suitable for a drying device for drying clothes and the like, and such a dehumidifying and warming device. The present invention relates to a drying device and a washing dryer.

  A conventional dehumidifying and heating apparatus will be described with reference to FIGS. FIG. 9 is a schematic diagram showing a system configuration of a dehumidifying and warming apparatus showing a conventional example. FIG. 10 is a Mollier diagram of a dehumidifying and heating apparatus showing a conventional example.

  The dehumidifying and warming device includes a heat pump device 105 including a compressor 101, a condenser 102, a decompression mechanism 103, and an evaporator 104, an air inlet 106, an evaporator 104, a condenser 102, and an air outlet 107 in this order. And a wind circuit 108 through which the air flows (see, for example, Patent Document 1).

  The operation of the dehumidifying and warming apparatus configured as described above will be described below.

  First, as the operation of the heat pump, when the compressor 101 is driven, the gas refrigerant is compressed to become a high-temperature and high-pressure gas refrigerant and flows into the condenser 102. The gas refrigerant flowing into the condenser 102 exchanges heat with air (a in FIG. 10), the air is heated, the refrigerant is cooled and condensed, and changes into a high-pressure liquid refrigerant.

  Next, the high-pressure liquid refrigerant is depressurized by the decompression mechanism 103 to become a low-temperature low-pressure liquid refrigerant or a gas-liquid two-phase refrigerant. This refrigerant flows into the evaporator 104, exchanges heat with air, cools the air, heats the refrigerant to become a low-pressure gas refrigerant (b in FIG. 10), and is sucked into the compressor 1.

  On the other hand, the high-humidity air flowing in from the air inlet 106 first flows into the evaporator 104 and is cooled. At this time, when the air is cooled below the dew point temperature, condensation is formed on the surface of the evaporator 104 and the air is dehumidified.

  Next, it flows into the condenser 102, is heated, becomes high-temperature, low-humidity air, and exits from the air outlet 7 to the outside of the dehumidifying and warming device. The heating amount at this time is the input amount (c in FIG. 10) of the compressor 1 obtained by subtracting the cooling amount (b in FIG. 10) in the evaporator 104 from the heating amount in the condenser 102 (a in FIG. 10). The temperature of the air that is heated and leaves the air outlet 107 becomes higher than the temperature of the air that flows in from the air inlet 106.

  In recent years, such a dehumidifying and warming device has been used in clothes dryers. Next, the case where a dehumidification warming apparatus is used for a clothes dryer is demonstrated.

  FIG. 11 is a side sectional view of a clothes dryer showing a conventional example.

Inside the outer tub 130 installed inside the housing 110, a cylindrical and horizontal axis type clothing storage unit 150 for storing the clothing 140 is rotatably provided and is driven to rotate by a drive motor 160. . On the front surface of the housing 110, there are provided an opening 110a through which clothes 140 are taken in and out and a door 170 for opening and closing the opening 110a.

  Similar openings 130a and 150a are also provided on the front side of the outer tub 130 and the clothing storage portion 150, respectively. The opening 130a of the outer tub 130 is connected to the opening 110a of the housing 110 in a watertight manner by a bellows 180. ing.

  The blower 120 constituting the blowing means is provided on the outer peripheral surface of the outer tub 130 so as to be positioned in a corner space (upper portion of the casing 110) formed by the upper surface 110d of the casing 110 and the outer tub 130. . The heat pump device 105 described above is provided in the lower part of the back surface 110b of the housing 110.

  Hereinafter, the drying operation of such a clothes dryer will be described.

  The heat pump device 105 is operated, and the blower 120 is operated in parallel with the heat pump device 105. Due to the heat radiation of the condenser 102, the heated warm air is blown from the air circuit 108 through the duct 121 a into the clothing storage unit 150 through the air supply port 141. The clothing container 150 is rotationally driven by the drive motor 160, and the clothing 140 is stirred up and down.

  The warm air supplied into the clothing container 150 takes moisture when passing through the gaps in the clothing 140, and in the wet state passes through the blower 120 from the circulation duct 160 through the exhaust port 151 of the outer tub 130, and passes through the duct 121b. To the evaporator 104. When the wet warm air passes through the evaporator 104, the sensible heat and latent heat are deprived and dehumidified, and separated into dry air and condensed water.

When the dry air subsequently passes through the condenser 102, it is heated again by the condenser 102 to become warm air, and is supplied again into the outer tub 130 and the clothing storage portion 150 in the same manner as described above. Repeat the cycle. The condensed water flows into a drain pan 170 provided in the lower part of the evaporator 104 and is discharged out of the apparatus through a drain port (not shown). Here, since the air can contain more moisture as the temperature is higher, it is more effective to raise the air temperature sooner after the drying operation is started.

(Embodiment 1)
FIG. 1 is a schematic diagram showing a system configuration of a dehumidifying and warming device according to Embodiment 1 of the present invention. FIG. 2 is a Mollier diagram during air warming obtained by the dehumidifying warmer. FIG. 3 is a Mollier diagram during heat dissipation obtained by the dehumidifying and warming device.

  The dehumidifying and warming device includes a compressor 1, a condenser 2, a pressure reducing mechanism 3, a heat storage tank 4 and an evaporator 5, and an evaporator 5 and a condenser 2 disposed therein, and an air inlet 6 , The evaporator 5, the condenser 2, and the air flow outlet 7 in this order. Further, a blower 17 is disposed inside the wind circuit 9.

  In the heat storage tank 4, a heat exchanger 18 for heat storage and water 4a as a heat storage material are enclosed. Since the water 4a is inexpensive and has a large solidification latent heat, it is desirable from the viewpoint of reducing the size of the device. In addition, the heat storage material may be a liquid such as an antifreeze or ethanol or a gel-like medium, and is preferably a latent heat storage material that undergoes a phase change at the operating temperature.

  A unitized dehumidifying and warming device can be configured by arranging and storing the above-described constituent elements in, for example, a housing 10 indicated by a one-dot chain line.

  The operation of the dehumidifying and warming apparatus configured as described above will be described below.

  First, as the operation of the heat pump device 8, when the compressor 1 is driven, the refrigerant is compressed, becomes a high-temperature high-pressure gas refrigerant, and flows into the condenser 2. The gas refrigerant flowing into the condenser 2 exchanges heat with air, the air is heated, the refrigerant is cooled and condensed, and changes in phase to a high-pressure liquid refrigerant (a ′ in FIG. 2).

  Next, the high-pressure liquid refrigerant is depressurized by the depressurization mechanism 3, and becomes a low-temperature low-pressure liquid refrigerant or a gas-liquid two-phase refrigerant that is equal to or lower than the freezing point temperature of the water 4a as the heat storage material. This refrigerant first flows into the heat storage tank 4 and exchanges heat with water 4a as a heat storage material. Thereby, the water 4a is cooled and becomes ice. At this time, the refrigerant is heated to change into a low-pressure gas refrigerant (d ′ in FIG. 2).

  Next, the refrigerant flows into the evaporator 5 and slightly exchanges heat with air. As a result, the refrigerant is further heated to become a low-pressure gas refrigerant and sucked into the compressor 1 (b ′ in FIG. 2).

  On the other hand, the low-temperature air at the initial stage of the drying operation flows from the air inlet 6 by the operation of the blower 17, is slightly cooled and dehumidified by the evaporator 5, then flows into the condenser 2, and is heated here. The air flows out from the air outlet 7 to the outside of the dehumidifying and warming device.

  At this time, in the case of the conventional dehumidifying / heating apparatus, the heating amount is only the input amount of the compressor 1 (c in FIG. 10) as described above. In the temperature device, the amount of heat stored is not cooled, so the amount of heat is added to the input of the compressor 1 (c ′ in FIG. 2) and the amount of heat stored (d ′ in FIG. 2) is added. The temperature can be raised.

  Next, when the air is heated and the temperature rises, the evaporation temperature of the refrigerant also rises. And if it becomes higher than the temperature of the water 4a which is a heat storage material, a refrigerant | coolant can be cooled further (e 'of FIG. 3), and the dehumidification and cooling of air are accelerated | stimulated by increasing the amount of heat exchange in the evaporator 5 (F ′ in FIG. 3).

  By the above operation, the dehumidifying and warming device can increase the temperature of the air from the start of the drying operation and increase the dehumidifying effect after the air reaches a predetermined temperature.

(Embodiment 2)

And the condenser 2, the first wind circuit 11 through which air flows in the order of the air inlet 6, the evaporator 5, the condenser 2, and the air outlet 7, and the evaporator 5, bypassing the air inlet 6, A second wind circuit 12 through which air flows in the order of the condenser 2 and the air outlet 7, and an air volume for performing an operation of switching the air from the air inlet 6 to the first wind circuit 11 or the second wind circuit 12. And an adjusting device 13. The air volume adjusting device 13 can be configured by, for example, an electric damper device that can be stopped halfway in the range from fully open to fully closed.

  An air temperature sensor 14 that detects the temperature of the air that has passed through the condenser 2 is attached to the air outlet 7. Based on the temperature detected by the air temperature sensor 14, the air volume control device 13 a operates the air volume adjusting device 13. The air volume flowing through the first wind circuit 11 and the air volume flowing through the second wind circuit 245 are adjusted. A refrigerant temperature sensor 15 that detects the temperature of the refrigerant flowing into the heat storage tank 4 is attached to the inlet refrigerant pipe of the heat storage tank 4 and detects the evaporation temperature in the heat storage tank 4.

The operation of the dehumidifying and warming apparatus configured as described above will be described below. Here, for convenience, it is assumed that the temperature of the air that has passed through the condenser 2 is below a predetermined value, and the air volume adjusting device 13 is in a solid line.

  First, as the operation of the heat pump device 8, when the compressor 1 is driven at the initial stage of the drying operation, the gas refrigerant is compressed to become a high-temperature and high-pressure gas refrigerant and flows into the condenser 2. The gas refrigerant flowing into the condenser 2 exchanges heat with air, the air is heated, the refrigerant is cooled and condensed, and changes in phase to a high-pressure liquid refrigerant (a ″ in FIG. 5).

  Next, the high-pressure liquid refrigerant is depressurized by the decompression mechanism 3a, and becomes a low-temperature low-pressure liquid refrigerant or a gas-liquid two-phase refrigerant that is equal to or lower than the freezing point temperature of the water 4a as the heat storage material. This refrigerant flows into the heat storage tank 4 and exchanges heat with water 4a as a heat storage material, and the water 4a is cooled to become ice. At this time, the refrigerant is heated to change into a low-pressure gas refrigerant (d ″ in FIG. 5), and then sucked into the compressor 1 through the evaporator 5.

  On the other hand, the low-temperature air in the initial stage of the drying operation flows from the air inlet 6 and then flows to the second wind circuit 12 that does not pass through the evaporator 5 and flows into the condenser 2 where it is heated and heated. The air flows out of the dehumidifying and heating device from the air outlet 7.

  The heating amount of the conventional dehumidifying / warming device at the beginning of the drying operation is only the input of the compressor 101 (c in FIG. 10) as described above, but in the dehumidifying / warming device of the second embodiment, Since heat is stored in the heat storage tank 4, the air is not cooled, and all the capacity of the condenser 2 (a ″ in FIG. 5) is used for heating the air, so that the temperature of the air can be increased more quickly.

Next, when the temperature of the air outlet 7 measured by the air temperature sensor 14 reaches a predetermined temperature, the air volume adjusting device 13 closes the second wind circuit 12 as indicated by the broken line by the signal of the air volume control device 13a. Operates on. As a result, the air volume flowing through the second wind circuit 12 is reduced, and the air volume flowing through the first wind circuit 11 is increased.

  Further, the decompression mechanism control means 16 operates based on the temperature detected by the refrigerant temperature sensor 15, adjusts the decompression amount of the decompression mechanism 3a, and controls so that the evaporation temperature of the refrigerant becomes high. Thus, by making the evaporation temperature of the refrigerant higher than the temperature of the water 4a as the heat storage material, the refrigerant can be further cooled by the amount indicated by d ″ in FIG. 6. As a result, b ″ in FIG. As can be seen, the amount of heat exchange in the evaporator 5 can be increased, and air dehumidification and cooling can be promoted.

  As a result, it is possible to provide a dehumidifying and warming device that greatly accelerates the temperature rise of the air from the start of the drying operation and greatly enhances the dehumidifying effect after the air reaches a predetermined temperature.

  The operation of the air volume adjusting device 13 has been described in terms of switching between the first wind circuit 11 and the second wind circuit 12, but the opening angle of the air volume adjusting device 13 is set according to the temperature detected by the air temperature sensor 14. By controlling and adjusting the amount of air flowing through the evaporator 5, the air dehumidified by the evaporator 5 can flow to the air outlet 7. As a result, a dehumidifying operation according to the situation can be obtained.

It flows into the housing 10 of the device.

  At this time, since the air volume control device 13 closes the first wind circuit 11 at the initial stage of the drying operation, the drying air flows to the second wind circuit 12 and is heated by the condenser 2. Thereafter, the air flows from the air outlet 7 into the outer tub 23 through the flexible connecting pipe 37 b and the air supply duct 38, and then flows into the rotary tub 25.

  The hot air supplied into the rotating tub 25 deprives moisture when passing through the gap between the clothes 24 and flows to the blower 31 through the exhaust duct 39 opened to the outer tub 23 in a wet state. The above flow indicated by the arrow is repeatedly circulated.

Thus, in the initial stage of the drying operation, the air for drying is exchanged with the condenser 2 without exchanging heat with the evaporator 5, so that the temperature rise of the air can be accelerated. In such a state, the amount of moisture that can be contained in the air is increased, and the evaporation of moisture from the garment 24 is easily promoted by the temperature (heat amount) of the heated air, so that drying is promoted.

  On the other hand, in the heat pump device 8, the gas refrigerant discharged from the compressor 1 flows into the condenser 2, heats the air, and becomes liquid refrigerant.

  Next, the pressure is reduced so that the evaporation temperature becomes 0 ° C. or less by the pressure reducing mechanism control means 16, and flows through the heat storage tank 4. In the heat storage tank 4, the rinse waste water (water) 4a as the heat storage material is cooled by the refrigerant to become ice, and the refrigerant is evaporated by this heat exchange action to become a gas refrigerant.

  Thus, in the heat storage tank 4, the latent heat of vaporization of the refrigerant is stored, and the gas refrigerant returns to the compressor 1.

  Next, when the temperature on the air outlet 7 side measured by the air temperature sensor 14 reaches a predetermined temperature, a signal is output from the air volume control device 13a to the air volume adjusting device 13, and the air volume adjusting device 13 receives the second air circuit. The air volume flowing through the first wind circuit 11 is increased by reducing the air volume flowing through the first air circuit 11.

  As a result, the dehumidification of the air is efficiently performed by flowing the air that has become hot and humid in the order of the evaporator 5 and the condenser 2. And the dew condensation water adhering to the evaporator 5 is stored in the drain pan 32 provided in the lower part. The water stored in the drain pan 32 can be supplied to the heat storage tank 4 by water supply means such as a pump and used as a heat storage material.

  Further, the decompression mechanism 3a is controlled by a signal from the decompression mechanism control means 16 based on the temperature detected by the refrigerant temperature sensor 15, and the refrigerant is further increased by setting the evaporation temperature of the refrigerant to be higher than the temperature of the water 4a as the heat storage material. Can be cooled.

  As a result, the amount of heat exchange in the evaporator 5 can be increased, and air dehumidification and cooling can be promoted. At this time, the heat storage material melts from the ice state and becomes water. This water is discharged to the outside by opening the on-off valve 34 when it is unnecessary, for example, when drying is completed.

  As a result, the temperature rise of the air from the start of the drying operation can be greatly accelerated, and the dehumidifying effect of the air after reaching the predetermined temperature can be greatly increased, so that the drying time can be shortened and the power consumption can be reduced. A washing dryer that can be reduced can be provided.

Next, a description will be given of a drying apparatus according to a fourth embodiment on which the dehumidifying and warming apparatus described in the second embodiment is mounted. Here, the same constituent elements as those of the third embodiment are denoted by the same reference numerals, and here, different parts from the previous third embodiment will be mainly described.

  FIG. 8 is a side sectional view of the washing / drying machine according to Embodiment 4 of the present invention.

  The heat storage tank 4 </ b> A is connected to the bottom of the outer tank 23 by an introduction pipe 30, and is configured such that drainage from the outer tank 23 flows into the heat storage tank 4 </ b> A.

  The outer shell 4b of the heat storage tank 4A has a structure in which a permeable material is used on the lower surface, and the water 4a stored inside penetrates with time and is discharged out of the heat storage tank 4A. And the water which permeate | transmitted outside from the thermal storage tank 4A is discharged | emitted out of the housing 21 from the drain pipe 40 provided in the bottom part of the housing 21. FIG. The water permeable material may be configured to form the side surface of the heat storage tank 4A.

Hereinafter, the operation | movement which shifted to the drying process from the spin-drying | dehydration process of the washing dryer provided with the said structure is demonstrated.

  After rinsing, when rinsing is completed, the rinse wastewater flows into the heat storage tank 4A through the introduction pipe 30 and accumulates in the heat storage tank 4A as a heat storage material. And the waste water exceeding the capacity | capacitance of the thermal storage tank 4A is discharged | emitted outside through the overflow pipe 35 and the drain pipe 40. FIG.

  Then, similarly to the third embodiment, the rotating tub 25 and the heat pump device 8 are driven to dry the clothes 24 and the like.

  The drainage of the water 4a in the heat storage tank 4A after the drying process is gradually discharged outside through the osmotic material without using the discharge mechanism because the outer shell 4b of the heat storage tank 4A is made of a permeable material. The structure can be simplified, and the troublesome drainage operation can be eliminated.

  Thus, according to the fourth embodiment, as in the third embodiment, the temperature rise of the air from the start of the drying operation is greatly accelerated, and the dehumidifying effect of the air after reaching the predetermined temperature is greatly increased. In addition to shortening the drying time and reducing power consumption, the convenience of the drainage operation can be made inexpensive and compact.
