Please refer to Figure 1 The clothes processing apparatus 100 includes a clothes container 10, an evaporator 20, a condenser 30, and a steam generator 40. The clothes container 10 is used to place clothes to be processed; the air inlet of the evaporator 20 is in communication with the air outlet of the clothes container 10, the air outlet of the evaporator 20 is in communication with the air inlet of the condenser 30, and the air outlet of the condenser 30 is in communication with the air inlet of the clothes container 10; the steam generator 40 is connected with the air outlet side of the evaporator 20 and the clothes container 10, so as to flow the steam generated by the steam generator 40 to the air outlet side of the evaporator 20 and the clothes container 10.

Wherein, the laundry container 10 can be a drum structure or a pulsator structure.

[0050] The evaporator 20 is used to reduce the temperature of the circulating air, so that the water vapor in the circulating air is condensed, and the dehumidification effect is achieved; the condenser 30 is used to increase the temperature of the circulating air, so as to obtain circulating air with higher temperature and dryness, which is beneficial to the drying of the laundry in the laundry container 10.

[0051] The air inlet of the evaporator 20 is communicated with the air outlet of the laundry container 10, the air outlet of the evaporator 20 is communicated with the air inlet of the condenser 30, and the air outlet of the condenser 30 is communicated with the air inlet of the laundry container 10, that is, the circulating air flows from the evaporator 20 to the condenser 30, and then from the condenser 30 to the laundry container 10, and then from the laundry container 10 to the evaporator 20, and circulates reciprocally, so as to dry the laundry in the laundry container 10.

[0052] Wherein, the first fan 11 is used to make the circulating air flow. It can be understood that the position of the first fan 11 is not limited by the present application, for example, the first fan 11 can be arranged between the laundry container 10 and the evaporator 20, or between the laundry container 10 and the condenser 30, or between the evaporator 20 and the condenser 30.

[0053] The steam generator 40 is connected with the air outlet side of the evaporator 20 and the laundry container 10, so as to flow the steam generated by the steam generator 40 to the air outlet side of the evaporator 20 and the laundry container 10. It can be understood that the steam generated by the steam generator 40 can flow to the air outlet side of the evaporator 20 and the laundry container 10 at the same time; or the steam generated by the steam generator 40 can flow to the air outlet side of the evaporator 20 first, and then flow to the laundry container 10; or the steam generated by the steam generator 40 can flow to the laundry container 10 first, and then flow to the air outlet side of the evaporator 20.

[0054] Wherein, the air outlet side of the evaporator 20 can be understood as the part between the evaporator 20 and the laundry container 10 in the flow direction of the circulating air.

[0055] The steam generator 40 is a device that uses electric energy or other energy to heat water and convert it into steam. Among them, the steam generator 40 is usually configured with a water tank by itself. It can be understood that the clothes treatment equipment 100 also includes a water collecting container arranged below the condenser 30, and the water tank is in communication with the water collecting container, that is, the water in the water tank is the water condensed by the evaporator 20 from the water vapor in the circulating air; or, the water tank has a water inlet, that is, the water in the water tank can be manually added; or, the water tank includes a connecting pipe for connecting with an external water source, for example, the external water source can be a water faucet, that is, the water tank is connected with the water faucet through the connecting pipe.

[0056] Optionally, the steam generator 40 is located below the clothes container 10 and above the base.

[0057] The clothes treatment equipment 100 provided by the embodiment of the present application has the following beneficial effects: in operation, the circulating air is heated into high-temperature dry air after passing through the condenser 30, then enters the clothes container 10 to take away the moisture on the clothes, and then the wet air enters the evaporator 20 to condense water and then enters the condenser 30 to be heated again, and the cycle is repeated to realize the drying of the clothes. When the ambient temperature is low or at the initial stage of drying, the high-temperature steam generated by the steam generator 40 can flow to the air outlet side of the evaporator 20 to increase the temperature of the circulating air at the air outlet side of the evaporator 20, improve the temperature rising speed at the initial stage of operation, and shorten the drying time. In addition, the high-temperature steam generated by the steam generator 40 can also flow into the clothes container 10 to remove wrinkles from the clothes in the clothes container 10.

[0058] Among them, the drying time can be shortened by 10% to 15% under normal temperature environment; the drying time can be shortened by 20% to 30% under low temperature environment.

[0059] Please refer to Figure 1 In some embodiments, the steam generator 40 is connected with the condenser 30, so that the steam generated by the steam generator 40 is sprayed to the surface of the condenser 30. That is, the high-temperature steam generated by the steam generator 40 is sprayed to the surface of the condenser 30, so that the temperature of the circulating air is increased, and the circulating air entering the clothes container 10 can take away more moisture. In this way, the heat exchange amount of the evaporator 20 is increased, the refrigerant circulation flow of the heat pump system is increased, and thus the condenser 30 can provide more heat, so that the circulating air is quickly heated.

[0060] Please refer to Figure 2 In some embodiments, the steam generator 40 is connected between the evaporator 20 and the condenser 30, so that the steam generated by the steam generator 40 can be sprayed between the evaporator 20 and the condenser 30. Therefore, the circulating air coming out of the evaporator 20 is first heated by the high-temperature steam and then heated by the condenser 30, so as to quickly increase the temperature of the circulating air.

[0061] Please refer to Figure 1 andFigure 2 In some embodiments, the steam generator 40 has a first steam outlet 41 and a second steam outlet 42, and the clothing handling device 100 includes a first steam pipe 43 and a second steam pipe 44. The first steam outlet 41 is connected to the air outlet side of the evaporator 20 through the first steam pipe 43, and the second steam outlet 42 is connected to the clothing container 10 through the second steam pipe 44.

[0062] That is, the high-temperature steam generated by the steam generator 40 can flow to the air outlet side of the evaporator 20 through the first steam outlet 41 and the first steam pipe 43, or it can flow into the clothing container 10 through the second steam outlet 42 and the second steam pipe 44.

[0063] In other embodiments, such as Figure 3 As shown, the steam generator 40 has a first steam outlet 41, which is connected to the air outlet side of the evaporator 20 via a first steam pipe 43. The first end of the second steam pipe 44 is connected to the first steam pipe 43, and the second end of the second steam pipe 44 is connected to the clothing container 10. Alternatively, the steam generator 40 has a first steam outlet 41, which is connected to the clothing container 10 via a second steam pipe 44. The first end of the first steam pipe 43 is connected to the second steam pipe 44, and the second end of the first steam pipe 43 is connected to the air outlet side of the evaporator 20.

[0064] Please refer to Figure 1 and Figure 3 In some embodiments, a first valve 431 is provided on the first steam pipe 43, and a second valve 441 is provided on the second steam pipe 44.

[0065] Optionally, the first valve 431 and the second valve 441 are automatic valves. For example, the first valve 431 and the second valve 441 are solenoid valves, that is, the first valve 431 and the second valve 441 can be controlled by a controller to automatically open and close.

[0066] The processing procedure of the garment processing equipment 100 is as follows: Figure 5As shown, the drying process begins with the garment container 10 rotating. If the garment is first treated (i.e., wrinkle removal) and then dried, the first valve 431 is closed and the second valve 441 is opened. The first fan 11 operates at low or zero speed until the programmed steam setting time is reached, completing the garment treatment. Afterward, the first valve 431 is opened and the second valve 441 is closed. The first fan 11 operates at its normal speed. When the temperature of the circulating air entering the garment container 10 reaches the set temperature, the first valve 431 closes, and the steam generator 40 stops operating. The drying process ends when the drying condition is met or the timer expires. Alternatively, the garment can be dried directly. The first valve 431 is opened and the second valve 441 is closed. The first fan 11 operates at its normal speed. When the temperature of the circulating air entering the garment container 10 reaches the set temperature, the first valve 431 closes, and the steam generator 40 stops operating. The drying process ends when the drying condition is met or the timer expires. The drying condition refers to the conditions under which the system determines the garment is dry.

[0067] In other embodiments, such as Figure 3 As shown, the steam generator 40 has a first steam outlet 41, which is connected to the air outlet side of the evaporator 20 via a first steam pipe 43. The first end of the second steam pipe 44 is connected to the first steam pipe 43, and the second end of the second steam pipe 44 is connected to the clothing container 10. A two-position three-way valve is provided at the connection between the first end of the second steam pipe 44 and the first steam pipe 43. The two-position three-way valve can replace the first valve 431 and the second valve 441.

[0068] In some embodiments, the garment processing device 100 further includes a filter 70 connected between the garment container 10 and the evaporator 20.

[0069] Optionally, filter 70 is a filter screen.

[0070] Based on the above solution, the filter 70 is used to filter out lint and other debris from the circulating air flowing out of the clothing container 10, so as to prevent debris from adhering to the surface of the evaporator 20 and the condenser 30 and affecting heat exchange.

[0071] Please refer to Figure 1 In some embodiments, the garment processing device 100 further includes a first pipe 51, a second pipe 61, a throttle valve 50, and a compressor 60; one end of the first pipe 51 is connected to a condenser 30, and the other end of the first pipe 51 is connected to an evaporator 20, and the throttle valve 50 is disposed on the first pipe 51; one end of the second pipe 61 is connected to the evaporator 20, and the other end of the second pipe 61 is connected to the condenser 30, and the compressor 60 is disposed on the second pipe 61.

[0072] The evaporator 20, the condenser 30, the first pipeline 51, the second pipeline 61, the throttling device 50 and the compressor 60 jointly constitute a heat pump system, which uses the phase change heat absorption and heat release characteristics of the refrigerant medium (for example, refrigerant) to achieve the purposes of dehumidification and heating and drying.

[0073] In the condenser 30, the high-temperature and high-pressure gaseous refrigerant medium is converted into liquid refrigerant medium and releases heat to the surrounding environment to achieve temperature rise, thereby achieving the purposes of heating and drying the circulating air. The liquid refrigerant medium enters the evaporator 20 through the throttling device 50, and in the evaporator 20, the liquid refrigerant medium absorbs heat from the surrounding environment and is converted into gaseous refrigerant medium to achieve temperature drop, so that the water vapor in the circulating air is condensed into liquid water, thereby achieving the purpose of dehumidification. Then, the gaseous refrigerant medium is converted into high-temperature and high-pressure gaseous refrigerant medium by the compressor 60 and enters the condenser 30, so as to realize the circulation of the refrigerant medium.

[0074] Please refer to Figure 4 In some embodiments, the clothes treatment apparatus 100 further comprises a moisture absorption and dehumidification device 90 connected between the evaporator 20 and the condenser 30, and the steam generator 40 flows the generated steam to the air outlet side of the moisture absorption and dehumidification device 90.

[0075] During drying, the evaporator 20 first condenses and dehumidifies the circulating air, and then the moisture absorption and dehumidification device 90 adsorbs the moisture in the circulating air to quickly dehumidify. At the same time, the moisture absorption and dehumidification device 90 and the high-temperature steam can first assist in heating the circulating air, and then the circulating air is heated by the condenser 30 to achieve the purpose of quickly heating the clothes in the clothes container 10, quickly complete the drying and heating stage, and shorten the time of the drying start stage.

[0076] Moreover, the circulating air after dehumidification by the evaporator 20 has low temperature and low dew point temperature, and the moisture absorption and dehumidification device 90 is arranged between the evaporator 20 and the condenser 30, which is beneficial to the secondary adsorption and dehumidification of the moisture absorption and dehumidification device 90.

[0077] In some embodiments, the moisture absorption and dehumidification device 90 comprises a shell and a moisture absorption and dehumidification rotating disc arranged in the shell. The shell is divided into a moisture absorption zone 91 and a desorption zone 92. The moisture absorption zone 91 is connected between the evaporator 20 and the condenser 30, and the steam generator 40 flows the generated steam to the air outlet side of the moisture absorption zone 91. The air inlet side of the desorption zone 92 is connected with an air inlet duct 93, and the air outlet side of the desorption zone 92 is connected with an air outlet duct 94.

[0078] The shape of the shell can be designed according to actual working condition requirements, and only needs to include at least two functional areas of the moisture absorption area 91 and the desorption area 92. The shape of each functional area can also be designed according to actual needs, and can be square, triangular, circular, or sector-shaped, as long as the moisture absorption area 91 and the desorption area 92 are isolated from each other. The sector-shaped structure can more effectively and reasonably utilize the space.

[0079] The moisture absorption and desorption turntable can be a honeycomb or corrugated turntable carrying a moisture absorbent, which can absorb and desorb / absorb water vapor to realize repeated desorption and regeneration. Alternatively, the moisture absorption and desorption turntable includes inorganic / organic fiber carriers (such as ceramic, glass fiber, etc.), and the fiber carriers are coated with a moisture absorbent, which is uniformly distributed between the fiber carriers and the surface of the fiber carriers to realize the adsorption of air moisture.

[0080] The moisture absorbent can be a molecular sieve (including but not limited to A-type molecular sieve, X / Y-type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc. single crystal molecular sieve or mixed crystal molecular sieve, etc.), zeolite, modified / synthetic zeolite, high molecular dilute moisture absorbent, alkali metal aluminosilicate, lithium chloride, silica gel, modified silica gel, activated alumina, etc. materials with moisture absorption performance.

[0081] It can be understood that a second fan 931 can be arranged on the air inlet duct 93, or a second fan 931 can be arranged on the air outlet duct 94.

[0082] Based on the above scheme, the moisture absorption and desorption turntable can be circulated between the moisture absorption area 91 and the desorption area 92. The part of the turntable that rotates to the moisture absorption area 91 adsorbs the moisture in the air, and then the part of the turntable that adsorbs the moisture rotates to the desorption area 92 to desorb the moisture. The part of the turntable that desorbs the moisture rotates to the moisture absorption area 91 to adsorb the moisture again, so as to repeatedly remove the moisture in the air, thereby achieving the purpose of moisture absorption and desorption.

[0083] Please refer to Figure 4 In some embodiments, the air inlet side of the desorption area 92 is provided with a heater 921.

[0084] Alternatively, the heater 921 is a heating wire. Of course, the heater 921 can also be a steam coil, a condenser, etc.

[0085] Based on the above scheme, the heater 921 can quickly dry the moisture absorbent in the moisture absorption and desorption device 90, so as to further improve the desorption efficiency and further realize the rapid regeneration of the moisture absorption and desorption device 90.

[0086] In other embodiments, the heater 921 can be arranged on the air inlet duct 93.

[0087] Please refer to Figure 4In some embodiments, when the moisture absorbing and dehumidifying device 90 is arranged between the evaporator 20 and the condenser 30, the clothes treating apparatus 100 further comprises a bypass air duct 80 and a switching mechanism 81, the bypass air duct 80 is arranged in parallel with the moisture absorbing and dehumidifying device 90, and the switching mechanism 81 is used to control the circulating air to pass through the bypass air duct 80 or the moisture absorbing and dehumidifying device 90.

[0088] Optionally, the first end of the bypass air duct 80 is connected between the evaporator 20 and the moisture absorbing and dehumidifying device 90, and the second end of the bypass air duct 80 is connected between the moisture absorbing and dehumidifying device 90 and the condenser 30, so as to arrange the bypass air duct 80 in parallel with the moisture absorbing and dehumidifying device 90. At this time, the switching mechanism 81 comprises a damper, which can be arranged at the connection between the first end of the bypass air duct 80 and the circulating air duct or at the connection between the second end of the bypass air duct 80 and the circulating air duct, and the circulating air is controlled to pass through the bypass air duct 80 or the moisture absorbing and dehumidifying device 90 by turning over the damper. The circulating air duct is the main channel for circulating the circulating air.

[0089] Based on the above scheme, the number of dampers can be reduced, and only one damper needs to be operated to control the circulating air to pass through the bypass air duct 80 or the moisture absorbing and dehumidifying device 90, which is convenient to control.

[0090] Of course, the first end and the second end of the bypass air duct 80 can also be connected to the evaporator 20 and the condenser 30, respectively. At this time, the switching mechanism 81 comprises a first damper and a second damper, the first damper is arranged on the circulating air duct, and the second damper is arranged on the bypass air duct 80; when the first damper is closed and the second damper is opened, the circulating air passes through the bypass air duct 80, and when the first damper is opened and the second damper is closed, the circulating air passes through the moisture absorbing and dehumidifying device 90.

[0091] In the drying starting stage, the evaporator 20 first condenses and dehumidifies the circulating air, and then the moisture in the circulating air is adsorbed by the moisture adsorption and dehumidification device 90 to quickly dehumidify; at the same time, the moisture adsorption and dehumidification device 90 can first be assisted to heat, and then heated by the condenser 30 to quickly heat the clothes in the clothes container 10, quickly complete the drying and heating stage, and shorten the time of the drying starting stage. When the outlet temperature of the clothes container 10 reaches the set value, the moisture adsorption and dehumidification device 90 stops working, and enters the drying intermediate stage, that is, the moisture adsorption and dehumidification device 90 does not participate in the work, and the clothes in the clothes container 10 are dried by using the evaporator 20 and the condenser 30. In the drying ending stage, the moisture content of the circulating air decreases, the condensing efficiency of the evaporator 20 decreases, and the moisture adsorption and dehumidification device 90 participates in the drying again to adsorb and dehumidify the circulating air dehumidified by the evaporator 20 for the second time to obtain circulating air with very low water content, and at the same time, the circulating air is heated once; after passing through the condenser 30, very dry hot air enters the clothes container 10 to quickly dry the clothes, so as to shorten the drying time. Moreover, in the drying ending stage, the water content of the circulating air decreases, and the temperature of the circulating air entering the clothes container 10 increases. Since the temperature rising stage is shortened, the time of the clothes exposed to high temperature is also reduced, and the clothes can be better protected during drying.
