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 with each other outside the drying chamber 20 through a return air duct 30; a gas driving device 40, wherein the gas 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 mounted to the return air duct 30 upstream of the condenser 52 for cooling air from the outlet vents 22; the heat exchanger 60 is provided with an overflow channel for flowing a cooling medium; a container 70, the container 70 being installed in the cabinet 10 for storing a cooling medium; the evaporator 53 is at least partially installed in the container 70 to lower the temperature of the cooling medium; both the inlet and outlet of the transfer channel communicate with the vessel 70 to form a cooling circuit.

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 at a lateral wall of the casing 10, 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 gas driving device 40 and the heat pump assembly are all activated. The compressor 51 drives the refrigerant to flow back to the compressor 51 after passing through the condenser 52 and the evaporator 53 in sequence; 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 is immersed in the cooling medium, 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 gas driving device 40 may be a fan or a suction pump, and is not limited herein. The 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 will flow through the condenser 52 and be heated before entering the drying chamber 20, the hot air can evaporate the moisture of the wet clothes quickly after entering the drying chamber 20, and the wet hot air is formed and flows out of the drying chamber 20 from the air outlet 22, and the wet hot air will flow through the heat exchanger 60 for cooling and dehumidifying 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; in this way, the cooling capacity generated by absorbing heat from the evaporator 53 stored in the cooling medium in the container 70 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 gas 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 more cold energy can be completed only by adopting the compressor with smaller power to accumulate the passing time so as to meet the cooling and dehumidifying requirements of the damp and hot air. Taking the clothes processing equipment 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 gas driving device 40 is not started, the low-power compressor 51 can be firstly operated, the low-power operation can not only preheat the condenser 52 so as to heat up more quickly in the clothes drying mode, but also enable the refrigerating capacity of the evaporator 53 to be stored by the cooling medium firstly, so that when the clothes drying mode is entered, the gas driving device 40 is started, the condenser 52 can heat the air more quickly, and the cooling loop can more fully cool the heat exchanger 60 so as to ensure that the heat exchanger 60 has enough dehumidifying efficiency.

In another application scenario, taking the clothes processing device 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 stage, the gas driving device 40 is not started, and the low-power compressor 51 is operated in advance for a period of time, so that the condenser 52 is preheated, and the refrigerating capacity of the evaporator 53 can be stored by the cooling medium firstly; in the drying stage, the gas driving device 40 is turned on, the preheated condenser 52 can be heated to the preset temperature more quickly, and the cooling medium with stored cooling capacity can also cool the heat exchanger 60 more sufficiently to ensure that the heat exchanger 60 has sufficient dehumidification efficiency. That is, the evaporator 53 may make the cooling medium store cold by continuous low-power refrigeration before drying the laundry; 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 gas 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 up to 100 ℃ may affect the plastic pipes and other parts in the return air duct 30 and perform the non-dehydration ineffective heat exchange with the heat exchanger 60. Exemplarily, as shown in fig. 3, fig. 3 is a schematic structural diagram of a further embodiment of the laundry treating apparatus of the present invention. The return air duct 30 has a heat dissipating opening 31, and the heat dissipating opening 31 is located downstream of the condenser 52; 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 in 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 parts such as plastic pipelines in the return air duct 30 is reduced. In the drying stage, the gas driving device 40 is opened and the heat dissipation valve is closed, so that the hot air can flow to the drying chamber 20 normally.

In the technical scheme of the clothes processing equipment of the utility model, the damp and hot air flowing out from the drying chamber 20 is cooled and dehumidified by the heat exchanger 60, so as to prevent the damp and hot air from flowing to the condenser 52 and the drying chamber 20 again; the flow passage of the heat exchanger 60 forms a cooling loop with the container 70, and the cooling liquid in the container 70 can store the refrigerating capacity of the evaporator 53 to keep the temperature lower; when the laundry treating apparatus is operated, the cooling medium flowing through the heat exchanger 60 may indirectly exchange heat with the hot and humid air and then flow back to the container 70, so as to improve the heat exchange effect of the heat exchanger 60. Before the wet and hot air is cooled and dehumidified, the compressor can be operated at low power, namely the evaporator 53 is 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 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 container 70 may be installed at the bottom of the cabinet 10, or may be installed at the middle of the height direction of the cabinet 10 or at another position. 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.

Illustratively, as shown in FIG. 1, the walls of the container 70 are 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 to reduce the loss of cooling capacity of the cooling medium.

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. Exemplarily, as shown in fig. 2, fig. 2 is a schematic structural diagram of another embodiment of the laundry treating apparatus of the present invention. The laundry treating apparatus further includes a heat generating member 90, and the heat generating member 90 is installed at the return duct 30 downstream of the condenser 52 in terms of air flow. The heating member 90 may be an electric heating wire or the like 90, and when the laundry to be dried is large, the heating member 90 may be turned on to perform auxiliary heating, so as to improve the drying efficiency of the laundry.

After the damp and hot air exchanges heat with the heat exchanger 60, condensed water is formed on the surface of the heat exchanger 60, and the condensed water can be directly discharged out of the return air duct 30 or collected through a water collection structure. Illustratively, the laundry treating apparatus further includes a water collector (not shown) for collecting the condensed water formed by the heat exchanger 60, so as to prevent the condensed water from overflowing the return air duct 30, and thus water leakage from the laundry treating apparatus is prevented. The water collector may be in communication with the container 70 to allow the condensed water to flow to the container 70.

The gas-driven device 40 may be located upstream of the heat exchanger 60 or downstream of the heat exchanger 60, without limitation. Illustratively, as shown in fig. 1, the air-driven device 40 is located upstream of the heat exchanger 60, and the upstream of the heat exchanger 60 is closer to the air outlet 22, so that the air-driven device 40 can more easily form a negative pressure on the air outlet 22 to drive the air in the drying chamber 20 to flow into the return air duct 30 more fully.

Illustratively, as shown in fig. 1, the flow inlet of the transfer channel communicates with the container 70 via a liquid driving device 80, and the liquid driving device 80 is used for driving the cooling medium in the container 70 towards the transfer channel. The liquid driving device 80 may be a liquid pump, and the liquid inlet thereof is communicated with the container 70 and the liquid outlet thereof is communicated with the flow passage. The flow rate of the cooling medium 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 more quickly and sufficiently removed.

Specifically, the laundry treating apparatus further includes a controller (not shown) electrically connected to the air driving device 40 and the liquid driving device 80, wherein the controller is configured to control a driving flow rate of the cooling medium by the liquid driving device 80 to be greater than a driving flow rate of the air by the air driving device 40; thus, the hot and humid air flowing through the heat exchanger 60 can be sufficiently heat-exchanged, so as to improve the cooling and dehumidifying effects of the hot and humid air.

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. 4, fig. 4 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 tubes 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 of the air and the heat exchanger 60 so as to improve the cooling effect of the air.

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