Description

  The present invention relates to a clothes drying apparatus for drying clothes with a heat pump used for a washing machine with a drying function for washing and drying clothes used in general households in the same tank, and a clothes dryer for drying only. .

  Conventionally, a dryer using this type of clothes drying apparatus has a configuration in which a part of drying air is exhausted to the outside and the outside air is sucked in order to operate the heat pump means in a stable state. (For example, see Patent Document 1).

  FIG. 8 is a system diagram showing the configuration of a conventional dryer and the flow of wind. As shown in FIG. 8, a compressor 31, a radiator 32 that dissipates the heat of the high-temperature and high-pressure refrigerant after compression, a throttle means 33 for reducing the pressure of the high-pressure refrigerant, and the pressure is reduced to a low pressure. A heat absorber 34 that removes heat from the surroundings of the refrigerant and a heat pump means 36 that are connected in order and connected by a pipe 35 so that the refrigerant circulates again to the compressor 31. The air passage 37 through which the drying air flows is configured to connect a radiator 32 serving as a means for heating the drying air, a drying chamber 38 containing clothes, and a heat absorber 34 that absorbs heat from the drying air. ing. The air passage 37 has a blower 39 that blows drying air. The heat balance means 40 includes an exhaust port 42 and an open / close damper 41 on the upstream side of the heat absorber 34 in the air passage 37 between the drying chamber 38 and the heat absorber 34, and downstream of the heat absorber 34. An intake port 43 and an open / close damper 44 are provided on the side.

  According to the above configuration, the drying air that has been given heat by passing through the radiator 32 takes moisture from the clothing 45 and dries the clothing. Since the drying air gives sensible heat as the amount of heat for water evaporation, the temperature decreases. However, since the drying air contains water vapor having substantially the same latent heat released from the garment 45, the drying air becomes high-humidity air. The enthalpy of the drying air that has been increased by the amount of heat is maintained substantially before and after contact with the garment 45.

  Here, considering the refrigerant refrigeration cycle in the heat pump means 36, the amount of heat released from the radiator 32 to the drying air is equal to the amount of heat taken from the drying air by the heat absorber 34 to the power consumed by the compressor 31. Increase by almost the equivalent amount. Further, since the amount of heat of the drying air is substantially maintained before and after contact with the clothing 45, if the drying air is circulated as it is, the amount of heat of the entire drying air increases and the amount of heat of the refrigerant in the heat pump means 36. Increases and the pressure increases. In the conventional example, in order to operate the heat pump means 36 in a stable state, a part of the drying air is exhausted to the outside by the first heat balance means 40, and the heat quantity from the air inlet 43 according to the exhausted air volume. Of small outside air.

  The drying air that has become humid due to contact with the clothing 45 at the exhaust port of the heat balance means 40 releases the amount of heat to the outside and reduces the amount of air, and is further cooled by the heat absorber 34 to take away sensible heat and latent heat. Dehumidified by condensation. The drying air that has been dehumidified and whose absolute humidity has decreased is mixed with the outside air flowing in from the air inlet 43 downstream of the heat absorber 34 and is heated by the radiator 32 again.

  The degree of opening of the open / close dampers 42 and 43 is controlled according to the amount of enthalpy due to a change in the amount of heat released by the radiator 32 and a change in temperature and humidity of the outside air.

As described above, in the heat balance means 40, a part of the heat amount of the drying air after passing through the clothing 45 is released to the outside, so that excessive increase in the temperature and pressure of the refrigerant is suppressed and overload of the compressor is prevented. Thus, stable operation of the heat pump means 36 is enabled. Furthermore, since the outside air does not pass through the heat absorber 34, the amount of heat transferred from the air to the refrigerant in the heat absorber 34 is reduced, and the load on the compressor 31 is reduced correspondingly, and the effect of releasing the heat amount is further enhanced.

  In particular, in a device that needs water supply for washing, such as a washing and drying machine, there is a faucet in the height direction, and the dimension in the height direction is limited in relation to this position, and it is desirable that it be low. Also in the width and depth directions, there are furniture and equipment such as a wash basin on both sides of the equipment, and there are restrictions on the dimensions in the width and depth directions due to the walls of the room. Therefore, the clothes drying apparatus provided in the apparatus is also desired to have a shape that allows the heat pump means to be installed in a compact manner.

  However, in the configuration of the conventional clothes drying apparatus, since the outside air is sucked, a predetermined space is provided between the heat absorber and the heat radiator of the heat pump means, and the intake port is disposed, so that the compact configuration cannot be achieved. It had the problem that.

  On the other hand, there is a heat exchanger in which a heat absorber and a heat radiator are integrated as a conventional technique, assuming that no space is provided between the heat absorber and the heat radiator (for example, Patent Document 2). There is a problem that an intake port for sucking air cannot be provided between the heat absorber and the heat radiator.

  The present invention solves the above-mentioned conventional problems, does not provide a space between the heat absorber and the heat radiator, has a compact configuration, releases heat to the outside, and increases the temperature and pressure of the refrigerant. An object of the present invention is to provide a clothing drying apparatus that can suppress, overload the compressor, and can stably operate the heat pump means.

  In order to solve the above-mentioned problems, the present invention is reduced in pressure by a compressor, a radiator that radiates heat from the compressed high-temperature and high-pressure refrigerant, and a throttle means for reducing the pressure of the high-pressure refrigerant. A heat pump means configured by connecting a heat absorber that takes heat from the surroundings with a refrigerant through a pipe line through which the refrigerant circulates, a blower that blows drying air, the heat absorber, the radiator, and clothes for the drying air An air passage for returning to the heat absorber and circulating it again through the drying cabinet containing the air, and in the air passage, a part of the drying air is sent to the outside of the heat sink on the windward side of the drying cabinet. Integrated heat exchange that integrates the radiator and the heat sink by providing an air outlet that exhausts the outside air as part of the drying air, upstream of the exhaust port and the heat sink, and downstream of the exhaust port. The heat sink of the integrated heat exchanger is partially heated by air and refrigerant. The a configuration to limit smaller than other portions replacement amount.

  By constructing an integrated heat exchanger that integrates the heatsink and heat sink, it is possible to realize a compact heat pump means without providing a space between the heatsink and the heatsink. An exhaust port for discharging a part of the drying air to the outside on the windward side of the drying cabinet and an intake port for taking in the outside air to the leeward side of the exhaust port on the windward side of the heat absorber as a part of the drying air In addition to the heat dissipation effect by partially exhausting the drying air on the wind of the heat sink and the intake of outside air, the heat sink of the integrated heat exchanger partially changes the heat exchange amount between the air and the refrigerant. Since the structure is limited to be smaller than the part, the heat absorption by the heat absorber of the drying air passing through here is suppressed, the amount of heat transferred from the outside air to the heat absorber is reduced, and the effect of releasing the heat amount is achieved. The effect of further increase is obtained.

  According to a first aspect of the present invention, a compressor, a radiator that radiates heat of a high-temperature and high-pressure refrigerant after compression, a throttle means for reducing the pressure of the high-pressure refrigerant, and a refrigerant that has been reduced in pressure to reduce heat from the surroundings. A heat pump means configured by connecting a heat absorber to be taken away by a pipe line through which a refrigerant circulates, a blower for blowing drying air, and a drying chamber in which the drying air is put in the heat absorber, the radiator and clothing. And an air passage for circulating the air back to the heat absorber again, and the air passage vents a part of the drying air to the outside on the wind of the heat absorber and lee of the drying cabinet. And an intake port for taking in external air as part of the drying air on the windward side of the heatsink and leeward of the exhaust port. The heatsink and the heatsink are fin-and-tube type and share fins Heat conduction formed parallel to the tube rows at the fins It is composed of an integrated heat exchanger with functions divided into a heat sink side and a heat sink side by a slit that suppresses, and the heat absorber side of this integrated heat exchanger has a heat exchange amount between air and refrigerant in part It is configured to be smaller than the part, and by configuring it with an integrated heat exchanger that integrates the radiator and heat sink, there is no space between the heat absorber and the radiator, and the heat pump means is compact Can be realized.

  Further, the air passage has an exhaust port for discharging a part of drying air to the outside on the wind of the heat absorber and lee of the drying cabinet, and an external port on the wind of the heat absorber to the lee of the exhaust port. By providing an air inlet that sucks in air as part of the drying air, a portion of the hot and humid air from the drying cabinet to the heat sink is discharged from the air outlet and replaced with the ambient outside air that is drawn from the air inlet. . In the drying air that circulates, heat is dissipated by switching to the outside air on the wind of the heat absorber.

  Furthermore, since the heat sink of the integrated heat exchanger is configured to limit the amount of heat exchange between the air and the refrigerant to be smaller than that of the other parts, most of the air passing through this part is heat exchanged by the heat sink. Therefore, the amount of heat transferred from the outside air to the heat absorber is reduced, and the effect of further releasing the amount of heat can be obtained.

  In the second invention, in particular, a part of the heat absorber of the integrated heat exchanger of the first invention is not provided with a tube but only fins are provided to reduce the amount of heat exchange with air. Since the tube through which the refrigerant flows is not provided, the amount of heat exchange is considerably less than other parts, the amount of heat transferred from the outside air to the heat absorber is reduced, and the effect of releasing the amount of heat is further enhanced. .

  In the third invention, in particular, a part of the heat absorber of the integrated heat exchanger of the first invention is cut out of the heat exchanger to reduce the amount of heat exchange with the air, and heat exchange is performed. Since there is no heat exchanger as a heat absorber, there is almost no heat exchange amount, the amount of heat transferred from the outside air to the heat absorber becomes smaller, and the effect of further releasing the heat amount can be obtained.

  In the fourth aspect of the invention, in particular, the intake port of any one of the first to third aspects of the invention is close to a portion where the amount of heat exchange between the air and the refrigerant in the integrated heat exchanger is limited to be smaller than that of the other portions. A portion in which the outside air that has been sucked in is difficult to mix with the drying air that circulates on the wind of the heat absorber, and the amount of heat exchange between the air and the refrigerant in the integrated heat exchanger is limited to be smaller than other portions Therefore, the amount of heat transferred from the outside air to the heat absorber is reduced, and the effect of releasing the amount of heat is further increased.

  In the fifth aspect of the invention, in particular, the air passage of any one of the first to third aspects limits the amount of heat exchange between the air and the refrigerant in the integrated heat exchanger from the intake port to be smaller than that of the other portions. It has a partition wall or a separate air passage so that the outside air that has been sucked in does not mix with the drying air that circulates until it reaches the part. In addition, since the heat exchange amount between the air and the refrigerant in the integrated heat exchanger passes through a portion restricted to be smaller than other portions, the amount of heat transferred from the outside air to the heat absorber becomes smaller, and the effect of releasing the heat amount The effect is further increased.

  In the sixth aspect of the present invention, in particular, the heat absorber side in the fourth or fifth aspect of the heat sink is substantially perpendicular to the direction of the part where the heat exchange amount with the air in the heat absorber is smaller than the other part. It is configured to increase the amount of heat exchange with air, and compensates for the decrease in heat absorption performance of the heat sink due to the fact that there is a part where the heat exchange amount with air is reduced on the heat sink side, drying at high temperature and high humidity The working air can be sufficiently absorbed by the heat absorber.

The drum 12 rotates to stir the clothes, and the blower 8 generates a flow A of drying air. The drying air takes moisture from the clothes 15 in the drum 12 and becomes humid, and then is carried by the blower 8 through the air passage 9 to the heat absorber 19 of the heat pump means 7.

  On the other hand, when the compressor 16 is activated and the refrigerant circulates through the pipe line 20, the low-temperature refrigerant takes heat in the heat absorber 19, and the drying air is dehumidified and further carried to the radiator 17. In the radiator 17, the drying air is heated by heat radiation from the refrigerant having a high temperature, becomes high-temperature and low-humidity air, and is circulated into the drum 12 again. The clothes are dried by repeating the above.

  By configuring the integrated heat exchanger 22 in which the radiator 17 and the heat absorber 19 are integrated, a space between the heat absorber 19 and the radiator 17 is not provided, and a heat pump unit can be realized in a compact manner.

  Further, by providing the exhaust port 23 and the intake port 24 provided in the air passage 9, a part of the hot and humid air from the drum 12 toward the heat absorber 19 is discharged from the exhaust port 23 and is sucked from the intake port 24. It replaces the surrounding outside air. In the drying air that circulates, heat is dissipated by switching to the outside air on the wind of the heat absorber 19.

  Further, the heat absorber 19 of the integrated heat exchanger 22 has a configuration in which the heat exchange amount between the air and the refrigerant is limited to be smaller than that of the other parts, and only the fins are provided without piping the tube through which the refrigerant passes. In the portion 25 (heat exchange amount limiting portion in FIG. 3), the amount of heat exchange with air is reduced, and the air passing through this portion is limited in heat exchange in the heat absorber than other portions, and the temperature The heat is received from the high-temperature refrigerant by the radiator 17 while the decrease is small, and the temperature becomes high.

  On the other hand, the air that passes through the other parts is reduced in amount by the amount of air that passes through the heat absorber, so that heat is exchanged. The amount of heat transferred to the vessel is reduced, and the effect of releasing the amount of heat is further enhanced.
