The utility model provides a clothes treatment equipment, clothes treatment equipment's form can have a lot, including clothing drying equipment and clothing washing equipment, specifically can be for the dryer or dry by the fire and wash the all-in-one. In the case of a clothes dryer, for example, a clothes dryer is various, and in the case of a drum type clothes dryer, the clothes treating apparatus includes a drum in which the clothes are placed, and the clothes rotate while the drum rotates, and the clothes come into contact with flowing high temperature air, and the high temperature air takes away moisture of the clothes (the moisture is taken away by evaporation), so that the clothes are rapidly dried.

In the embodiment of the present invention, as shown in fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a clothes treating apparatus of the present invention. The laundry treating apparatus includes: a housing 10; the drying chamber 20 is arranged in the machine shell 10, and the drying chamber 20 is provided with an air inlet 21 and an air outlet 22; the air inlet 21 and the air outlet 22 are communicated through a return air duct 30 outside the drying chamber 20; a first air driving device 40, wherein the first air driving device 40 is installed in the return air duct 30 and is used for driving air to flow from the air outlet 22 to the air inlet 21; the heat pump assembly comprises a compressor 51, a condenser 52 and an evaporator 53, wherein the compressor 51, the condenser 52 and the evaporator 53 are communicated in pairs through refrigerant pipes; the condenser 52 is installed in the return air duct 30 to heat the air flowing to the air inlet 21; a heat exchanger 60, the heat exchanger 60 being mounted to the return air duct 30 upstream of the condenser 52 for cooling the air from the outlet opening 22; the heat exchanger 60 is provided with a medium passage for accommodating a cooling medium to exchange and store the cooling capacity of the evaporator 53 by the cooling medium.

In the present embodiment, the cabinet 10 is used to form an overall exterior structure of the laundry treating apparatus. The cabinet 10 is provided with a mounting chamber for mounting parts of the laundry treating apparatus. The drying chamber 20 may be installed in the installation cavity in a drum shape to contain laundry; of course, the drying chamber 20 may be a fixed cylinder or the like. The casing 10 is provided with a pick-and-place opening communicated with the installation cavity, and the pick-and-place opening may be provided at the top of the casing 10 or may be provided on a lateral wall of the casing 10 in the transverse direction, which is not limited herein. The drying chamber 20 has a bottom and a mouth facing the access opening through which the user can put the laundry into the drying chamber 20 or take the laundry out of the drying chamber 20. The clothes treatment equipment can also comprise a door cover component, and the specific form and the moving mode of the door cover component are not limited, and only the access opening can be opened or closed. It can be understood that the door assembly closes the pick-and-place opening when the laundry treating apparatus is in operation, to prevent laundry from being thrown out of the drying chamber 20.

When the laundry treating apparatus performs the drying function, the first gas driving device 40 and the heat pump assembly are both activated. The compressor 51 drives the refrigerant to flow back to the compressor 51 after sequentially flowing through the condenser 52 and the evaporator 53; the refrigerant releases heat when passing through the condenser 52, and evaporates and absorbs heat in the evaporator 53 when passing through the evaporator 53. Since the evaporator 53 can exchange heat with the cooling medium in the heat exchanger 60, the refrigerant absorbs heat when evaporating to absorb heat, so that the temperature of the cooling medium is reduced, and the continuous heat absorption of the refrigerant to the cooling medium can continuously reduce the temperature of the cooling medium, so that the cooling medium can store cold. The cooling medium storing the cold energy can be kept at a low temperature, so that the surface temperature of the heat exchanger 60 can be lowered while flowing through the heat exchanger 60.

The first gas driving device 40 may be a fan or an air pump, which is not limited herein. The first air driving device 40 can drive the air in the return air duct 30 to flow into the drying chamber 20 from the air inlet 21 and flow out of the drying chamber 20 from the air outlet 22. The air in the return air duct 30 flows through the condenser 52 to be heated before entering the drying chamber 20, the hot air can evaporate moisture of wet clothes quickly after entering the drying chamber 20, and form damp and hot air to flow out of the drying chamber 20 from the air outlet 22, and the damp and hot air flows through the heat exchanger 60 to be cooled and dehumidified after entering the return air duct 30, so as to prevent the moisture and heat in the air from being directly brought to the condenser 52.

When the damp and hot air flows through the heat exchanger 60, the cooling medium can indirectly exchange heat with the damp and hot air through the heat exchanger 60, that is, the cooling medium can absorb the heat of the damp and hot air and then bring the heat back to the container 70, so that the heat exchange circulation of the cooling medium is realized; thus, the cooling capacity generated by the heat absorption from the evaporator 53 stored in the cooling medium can be effectively utilized to ensure the cooling effect of the hot and humid air.

In an application scenario, before the clothes are formally dried, that is, before the first air driving device 40 is started, the heat pump assembly can be started to preheat and pre-store the cold energy, so that the pre-storage of a large amount of cold energy can be completed only by accumulating the passing time of the compressor with a small power, so as to meet the cooling and dehumidifying requirements of the damp and hot air. Taking the clothes processing device as an all-in-one machine for drying and washing as an example, the clothes drying mode can be directly carried out after the clothes washing mode is finished, therefore, when the clothes washing mode is carried out, the first gas driving device 40 is not started, the low-power compressor 51 can be operated firstly, the low-power operation can enable the condenser 52 to be preheated so as to heat up more quickly in the clothes drying mode, and the refrigerating capacity of the evaporator 53 can be stored by the cooling medium firstly, so that when the clothes drying mode is entered, the first gas driving device 40 is started, the condenser 52 can heat the air more quickly, and the cooling medium with the stored refrigerating capacity can cool the heat exchanger 60 more fully so as to ensure that the heat exchanger 60 has enough dehumidifying efficiency.

In another application scenario, taking the clothes processing apparatus as a clothes dryer as an example, the clothes drying mode may include a refrigeration storage phase and a drying phase; in the refrigeration storage phase, the first gas driving device 40 is not started, and the compressor 51 operates for a period of time at a lower power, so that the condenser 52 is preheated, and the refrigeration capacity of the evaporator 53 can be stored by the cooling medium firstly; in the drying phase, the first gas driving device 40 is turned on, the operating power of the compressor 51 is increased, the preheated condenser 52 can be heated to the preset temperature more quickly, and the cooling medium with the stored cooling capacity can also cool the heat exchanger 60 more sufficiently. That is, before drying the laundry, the evaporator 53 may store cold energy in the cooling medium by continuous low-power refrigeration; therefore, in the drying stage, the compressor 51 does not need to keep high-power operation to enable the evaporator 53 to generate larger refrigerating capacity, and only needs to utilize the cooling medium stored with refrigerating capacity to cool the heat exchanger 60, so that the requirement on the high-power compressor can be omitted, and the overall cost of the clothes treatment equipment can be reduced.

It can be understood that before the first air driving device 40 is turned on, the hot air generated by the preheating of the condenser 52 in the return air duct 30 cannot enter the drying chamber 20, and the hot air with a temperature of more than 100 ℃ may affect the plastic parts in the return air duct 30 and perform ineffective heat exchange with the heat exchanger 60 without dehydration. Illustratively, as shown in fig. 2 and 4, the return air duct 30 has a heat dissipation opening 31, and the heat dissipation opening 31 is located downstream of the condenser 52 in the air flow; the laundry treating apparatus further includes a heat dissipation valve (not shown) for opening or closing the heat dissipation port 31. The heat dissipation opening 31 can be communicated with the outside of the casing 10, and the heat dissipation valve can be opened during the preheating and refrigeration storage stages of the heat pump assembly, so that the hot air in the return air duct 30 can be discharged in time through the heat dissipation opening 31, and the influence on the heat exchanger 60 and the plastic parts in the return air duct 30 is reduced. In the drying stage, the first gas driving device 40 is turned on, and the heat dissipation valve is closed, so that the hot air can flow to the drying chamber 20 normally.

In the technical solution of the clothes treating apparatus of the present invention, the heat exchanger 60 is used to cool and dehumidify the hot and humid air flowing out from the drying chamber 20, so as to prevent the hot and humid air from flowing to the condenser 52 and the drying chamber 20 again; the cooling medium in the heat exchanger 60 can store the cooling capacity of the evaporator 53 to maintain a lower temperature; when the clothes treating apparatus is in operation, the cooling medium of the heat exchanger 60 may indirectly exchange heat between the stored cold and the hot humid air, and then indirectly exchange heat between the absorbed heat and the evaporator 53. Before the wet and hot air is cooled and dehumidified, the compressor can be operated at low power, namely the evaporator 53 is pre-refrigerated at low power, so that the cooling liquid stores certain cold quantity in advance; thus, during the cooling and dehumidifying process, the evaporator 53 does not need to output a large cooling capacity, i.e., the compressor 51 does not need to operate at a large power, so that the need for a high-power compressor can be eliminated to reduce the overall cost of the laundry treating apparatus.

The heat exchanger 60 and the evaporator 53 may exchange heat in direct contact or indirectly through an intermediate medium. In one embodiment, the heat exchanger 60 partially penetrates out of the return air duct 30, and the portion of the heat exchanger 60 penetrating out of the return air duct 30 is in contact with the evaporator 53 for heat exchange.

In another embodiment, as shown in fig. 1 to 2, fig. 2 is a schematic structural diagram of another embodiment of the clothes treating apparatus of the present invention, and the medium channel is relatively closed. The heat exchanger 60 partially penetrates out of the return air duct 30, the clothes treatment equipment further comprises a second air driving device 90, the air inlet side of the second air driving device 90 faces the part of the heat exchanger 60 penetrating out of the return air duct 30, and the air outlet side of the second air driving device faces the evaporator 53. The second gas-driven apparatus 90 may be a fan or a suction pump. The second gas-driven device 90 can bring the heat of the heat exchanger 60 to the evaporator 53 more quickly by driving the gas flow to improve the cooling efficiency of the cooling medium in the heat exchanger 60. Therefore, when refrigeration storage is required, the compressor 51 and the second gas driving device 90 are turned on, the refrigerant in the evaporator 53 absorbs the heat of the cooling medium in the heat exchanger 60 due to evaporation, so that the temperature of the cooling medium is reduced, and the refrigerant absorbs the heat of the cooling medium continuously, so that the temperature of the cooling medium is reduced continuously, and the cooling medium can store cold.

The medium channel can be relatively closed, and can also be communicated with the outside; that is, the cooling medium may be stored only in the medium passage or may flow through the medium passage. Illustratively, as shown in fig. 3 and 4, the medium passage communicates with the outside; the laundry treating apparatus further includes a container 70 installed in the cabinet 10, the container 70 storing a cooling medium; both the inflow and outflow of the medium channel communicate with the container 70 to form a cooling circuit. The cooling circuit can realize the flow of the cooling medium between the medium channel and the container 70, so that the heated cooling medium can be remained in the container 70 and then supplemented to the medium channel by the low-temperature cooling medium in the container 70, thereby ensuring the continuous heat exchange effect.

Exemplarily, as shown in fig. 3 and 4, fig. 3 is a schematic structural diagram of a further embodiment of the laundry treating apparatus of the present invention; fig. 4 is a schematic view of a laundry treating apparatus according to another embodiment of the present invention. The inflow port of the medium passage communicates with the container 70 via a liquid driving device 80, and the liquid driving device 80 is configured to drive the cooling medium in the container 70 toward the medium passage. The liquid driving device 80 may be a liquid pump, and its liquid inlet is communicated with the container 70 and its liquid outlet is communicated with the overflow channel. When refrigeration storage is needed, the compressor 51, the second gas driving device 90 and the liquid driving device 80 are started, the cooling medium circulates in the heat exchanger 60, the refrigerant in the evaporator 53 absorbs heat of the cooling medium in the heat exchanger 60 due to evaporation, so that the temperature of the cooling medium is reduced, the continuous heat absorption of the refrigerant to the cooling medium enables the temperature of the cooling medium to be continuously reduced, and the cooling medium flows between the medium channel and the container 70, so that the refrigerating capacity can be stored in the cooling medium in the container 70. When the drying process is performed after the refrigeration storage, the flow rate of the cooling medium flowing through the heat exchanger 60 can be increased by the liquid driving device 80, so that the heat of the heat exchanger 60 can be taken away more quickly and sufficiently.

Illustratively, as shown in fig. 3 and 4, the wall of the container 70 is provided with an insulating layer 71. The heat insulating layer 71 may be disposed on the inner wall surface of the tank wall, may be disposed on the outer wall surface of the tank wall, and may also serve as an interlayer of the tank wall, which is not limited herein. The heat insulation layer 71 can reduce heat exchange between the cooling medium and the outside so as to reduce the loss of the cooling capacity of the cooling medium.

The container 70 may be installed at the bottom of the cabinet 10, or may be installed at the middle of the height of the cabinet 10 or at other positions. Since the container 70 contains the cooling medium, the overall weight is higher in the laundry treating apparatus, and thus the container 70 is mounted to the bottom of the cabinet 10, the overall center of gravity of the laundry treating apparatus can be lowered, and thus vibration can be reduced when the laundry treating apparatus is operated.

The cooling medium can be gas or liquid, and is not limited herein, and only can heat exchange and flow be satisfied. Illustratively, the composition of the cooling medium includes at least one of water and glycol; for example, the cooling medium can be a mixed solution of ethylene glycol and water, specifically 40% water and 60% ethylene glycol, and the freezing point of the cooling medium can reach below-40 ℃ so as to store more cold.

The air in the return air duct 30 may be heated only by the condenser 52, and may be heated by an additional auxiliary heating structure. Illustratively, as shown in fig. 2, the laundry treating apparatus further includes a heat generating member mounted to the return air duct 30 downstream of the condenser 52 in the air flow. The heating element can be an electric heating wire and other electric heating elements, and when the clothes to be dried are more, the heating element can be opened to assist in heating so as to improve the drying efficiency of the clothes.

The heat exchanger 60 may be in the form of a coil or a serpentine tube, which is not limited herein. Exemplarily, as shown in fig. 5, fig. 5 is a schematic structural diagram of an embodiment of the heat exchanger according to the present invention. The heat exchanger 60 comprises a plurality of heat exchange tubes 61 which are arranged side by side and connected end to end, and the overflowing channel is formed in the heat exchange tubes 61. The plurality of heat exchange pipes 61 can increase the flow path of the cooling medium in the heat exchanger 60 so that the cooling capacity of the cooling medium can be fully utilized, and can increase the contact area between the air and the heat exchanger 60 so as to improve the cooling effect on the air.

The above is only the optional embodiment of the present invention, and not limiting the patent scope of the present invention, all under the inventive concept of the present invention, the equivalent structure transformation made by the contents of the specification and the attached drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
