Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a drying system and clothing processing equipment. Background Technology

[0002] In the prior art, clothing processing equipment typically uses a heat pump system to dry the items to be dried. The heat pump system usually includes an evaporator, a condenser, a compressor, a throttling device, etc. The drying air passes through the evaporator and the condenser in sequence. The evaporator dehumidifies the drying air, and the condenser heats the drying air to provide high-temperature drying air to the items to be dried.

[0003] However, existing garment processing equipment still has relatively low drying efficiency. How to improve drying efficiency is one of the research and development topics in the industry. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the embodiments of this application add a moisture absorption and dehumidification device to the traditional heat pump system, and use a portion of the refrigerant output from the throttling component to regenerate the moisture absorption and dehumidification device. The evaporator and the moisture absorption and dehumidification device work together to dehumidify, so that the humidity of the drying air can be lower, thereby improving drying efficiency and shortening drying time. Moreover, there is no need to set up an additional dehumidification device for regenerating the moisture absorption and dehumidification device, reducing the cold loss at the cold end of the throttling component.

[0005] A first aspect of this application provides a drying system, comprising: a first drying subsystem including an evaporator, a compressor, a condenser, and a throttling component; a second drying subsystem including a moisture absorption and dehumidification device and a regeneration device, wherein the moisture absorption and dehumidification device is used to absorb moisture from drying air, and the regeneration device is used to regenerate the moisture absorption and dehumidification device after absorbing moisture; the evaporator, the moisture absorption and dehumidification device, and the condenser are arranged sequentially along the circulation path of the drying air; the regeneration device includes a cooler for dehumidifying the regeneration air, and the regeneration air is used to desorb the moisture absorbed by the moisture absorption and dehumidification device; and a valve assembly configured to selectively allow the refrigerant to flow from the throttling component through at least one of the evaporator and the cooler to the compressor.

[0006] Because it is equipped with an evaporator and a dehumidification device, and the drying air first passes through the evaporator and then the dehumidification device, the high-humidity drying air undergoes a first dehumidification process in the evaporator, reducing its humidity. Then, it undergoes a second dehumidification process in the dehumidification device, further reducing its humidity. This lower humidity allows the drying air to carry more moisture from the items being dried, thus increasing the drying speed. Furthermore, the dehumidification device is suitable for dehumidifying drying air with lower humidity, ensuring good dehumidification performance even in later stages of use. Since the evaporator, dehumidification device, and condenser are arranged sequentially along the circulation path of the drying air, a continuous supply of dry, high-temperature drying air can be provided. Because a cooler is included for dehumidifying the regenerated air, the regenerated air can remove moisture from the dehumidification device, maintaining its effective adsorption of moisture from the drying air. Because the valve assembly can selectively connect to the evaporator and / or cooler, all the cooling capacity of the refrigerant can be supplied to the evaporator, all of it to the cooler, or both. This allows the drying system to switch modes according to actual conditions, helping to reduce energy consumption and improve drying efficiency and effect. Since the cooler can connect to the throttling component, there is no need for an additional dehumidification device to regenerate the moisture absorption and dehumidification unit, and it also reduces cooling capacity loss at the cold end of the throttling component, resulting in greater energy savings.

[0007] In some embodiments, the valve assembly includes a reversing valve and an on / off valve, wherein the throttling element and the compressor are switched to be connected via the reversing valve via the evaporator or the cooler, and the evaporator and the cooler are switched on and off via the on / off valve.

[0008] Therefore, by controlling the reversing valve, the throttling component can be connected to the evaporator or cooler; by controlling the on / off valve, the on / off of the evaporator and cooler can be controlled, allowing the refrigerant to switch between four modes: passing only through the evaporator, passing through the evaporator first and then through the cooler, passing through the cooler first and then through the evaporator, and passing only through the cooler. This allows the drying system to switch modes according to actual conditions, which helps to reduce energy consumption and improve drying efficiency and drying effect.

[0009] In some embodiments, when the on / off valve connects the evaporator and the cooler, the throttling component is switched to be connected to one of the evaporator and the cooler via the reversing valve, and the compressor is switched to be connected to the other of the evaporator and the cooler via the reversing valve.

[0010] Therefore, when the throttling device is connected to the evaporator and the compressor is connected to the cooler, the refrigerant passes through the evaporator first and then the cooler, thus improving the condensation effect of the evaporator and enhancing the drying capacity of the first drying system. The first drying system can be used as the main drying system and the second drying system as an auxiliary drying system. When the throttling device is connected to the cooler and the compressor is connected to the evaporator, the refrigerant passes through the cooler first and then the evaporator, thus improving the condensation effect of the cooler and enhancing the drying capacity of the second drying system. The second drying system can be used as the main drying system and the first drying system as an auxiliary drying system.

[0011] In some embodiments, when the on / off valve disconnects the evaporator and the cooler, the throttling component is switched to be connected to one of the evaporator and the cooler via the reversing valve, and the compressor is switched to be connected to the same one of the evaporator and the cooler via the reversing valve.

[0012] Therefore, when the throttling device is connected to the evaporator and the compressor is connected to the evaporator, the cooling capacity of the refrigerant is only provided to the evaporator, which is suitable for situations where the humidity of the drying air is high. The evaporator can efficiently reduce the humidity of the drying air to a certain level. When the throttling device is connected to the cooler and the compressor is connected to the cooler, the cooling capacity of the refrigerant is only provided to the cooler, which is suitable for situations where the humidity of the drying air is low. The moisture absorption and dehumidification device can efficiently adsorb the residual moisture in the drying air.

[0013] In some embodiments, the inlet of the reversing valve is connected to the refrigerant output terminal of the throttling component, the first outlet of the reversing valve is connected to the refrigerant input terminal of the evaporator, the second outlet is connected to the refrigerant input terminal of the cooler, the refrigerant output terminals of the evaporator and the cooler are both connected to the refrigerant input terminal of the compressor, the refrigerant output terminal of the evaporator and the refrigerant input terminal of the cooler are connected in series through a first connecting pipe, the refrigerant output terminal of the cooler and the refrigerant input terminal of the evaporator are connected in series through a second connecting pipe, the on / off valve includes a first on / off valve disposed in the first connecting pipe and a second on / off valve disposed in the second connecting pipe, and the reversing valve is configured to connect the inlet to the first outlet or the second outlet.

[0014] Therefore, by controlling the reversing valve, the throttling component can be connected to the evaporator or the cooler. By controlling the first and second on / off valves, the evaporator and cooler can be connected or disconnected, and the order in which the refrigerant flows through the evaporator and cooler can be changed. This allows the refrigerant to switch between four modes: passing through the evaporator only, passing through the evaporator first and then the cooler, passing through the cooler first and then the evaporator, and passing through the cooler only. This enables the drying system to switch modes according to actual conditions, helping to reduce energy consumption and improve drying efficiency and effect.

[0015] In some embodiments, when the first on / off valve and the second on / off valve both disconnect the flow in the first connecting pipe and the second connecting pipe, the reversing valve selects to allow the refrigerant to flow from the throttling component through the evaporator or the cooler to the compressor by reversing.

[0016] Therefore, when the reversing valve is connected to the evaporator, the cooling capacity of the refrigerant is only provided to the evaporator, which is suitable for situations where the humidity of the drying air is high. The evaporator can efficiently reduce the humidity of the drying air to a certain level. When the reversing valve is connected to the cooler, the cooling capacity of the refrigerant is only provided to the cooler, which is suitable for situations where the humidity of the drying air is low. The moisture absorption and dehumidification device can efficiently adsorb the residual water vapor in the drying air.

[0017] In some embodiments, the reversing valve connects the evaporator to the throttling component and the cooler to the compressor, and the first on / off valve connects the evaporator and the cooler through the first connecting pipe; or, the reversing valve connects the cooler to the throttling component and the evaporator to the compressor, and the second on / off valve connects the evaporator and the cooler through the second connecting pipe.

[0018] Therefore, when the throttling device is connected to the evaporator and the compressor is connected to the cooler, the refrigerant passes through the evaporator first and then the cooler, thus improving the condensation effect of the evaporator and enhancing the drying capacity of the first drying system. The first drying system can be used as the main drying system and the second drying system as an auxiliary drying system. When the throttling device is connected to the cooler and the compressor is connected to the evaporator, the refrigerant passes through the cooler first and then the evaporator, thus improving the condensation effect of the cooler and enhancing the drying capacity of the second drying system. The second drying system can be used as the main drying system and the first drying system as an auxiliary drying system.

[0019] In some embodiments, the regeneration device further includes a heating device for heating the regeneration air. The refrigerant flow path connects the compressor, the heating device, the condenser, and the throttling component in series. Along the circulation path of the regeneration air, the cooler, the heating device, and the dehumidification device are arranged in sequence.

[0020] Because it is equipped with a heating device for heating the regeneration air, the regeneration air can remove a significant amount of moisture from the dehumidifier, maintaining the dehumidifier's ability to absorb moisture from the drying air. Since the heating device is connected to the compressor via a refrigerant flow path, there is no need for an additional electric heating device to regenerate the dehumidifier. This reduces heat loss at the compressor's hot end, resulting in greater energy savings, and also prevents the heat generated by the electric heating device from affecting the heat pump system.

[0021] In some embodiments, the heating device is connected downstream of the compressor and upstream of the condenser along the refrigerant circulation path to exchange heat with the refrigerant compressed by the compressor and the regeneration air.

[0022] Therefore, the high-temperature refrigerant flowing out of the compressor flows into the heating device, enabling the heating device to exchange heat with the regeneration air, raising the temperature of the regeneration air, which helps to improve the adsorption efficiency of the regeneration air on the moisture in the dehumidification device and accelerates the regeneration of the dehumidification device.

[0023] In some embodiments, the dehumidification device includes a rotating mechanism and a dehumidification component. The rotating mechanism is configured to drive the dehumidification component to rotate through a dehumidification zone and a regeneration zone. The dehumidification zone is located in the circulation path of the drying air, and the regeneration zone is located in the circulation path of the regeneration air.

[0024] Therefore, by rotating the moisture-absorbing and dehumidifying component, repeated moisture absorption and regeneration of the component can be achieved. Moreover, dehumidification and regeneration are carried out in two separate areas, allowing the regeneration air and drying air to circulate independently. This enables the moisture-absorbing and dehumidifying component to be regenerated while clothes are being dried, which helps to improve the drying speed.

[0025] In some embodiments, the drying system further includes a drying drum for carrying wet clothes. Along the circulation path of the drying air, the evaporator, the moisture absorption and dehumidification device, the condenser, and the drying drum are arranged in sequence, wherein the evaporator is used to dehumidify the drying air, and the condenser is used to heat the dehumidified drying air.

[0026] This provides a storage place for the items to be dried, and the drying air passes through the drying drum to dry the items.

[0027] In some embodiments, the drying system further includes a filter screen, and the evaporator, the moisture absorption and dehumidification device, the condenser, the drying cylinder, and the filter screen are arranged in sequence along the circulation path of the drying air.

[0028] Therefore, the drying air leaving the drying drum is filtered through a filter before entering the circulation path, which starts with the evaporator, thus reducing the probability of debris clogging the circulation path.

[0029] In some embodiments, the drying system further includes a first fan located in the circulation path of the drying air, the first fan providing circulation power for the drying air; the drying system further includes a second fan located in the circulation path of the regeneration air, the second fan providing circulation power for the regeneration air.

[0030] Thus, the drying air can circulate under the drive of the first fan, and the regeneration air can circulate under the drive of the second fan, thereby enabling rapid and effective drying and desorption.

[0031] The second aspect of this application provides a garment processing device, including the drying system provided in the first aspect above.

[0032] Because clothing processing equipment includes a drying system that can provide drying air with low humidity and switch modes, it can adapt to diverse usage needs, has strong flexibility, and can quickly and efficiently dry the clothes to be dried, reducing user waiting time and improving the user experience.

[0033] In some embodiments, the clothing processing equipment includes a dryer or a washer-dryer combo.

[0034] Therefore, it can quickly and efficiently dry clothes after washing, allowing users to use them immediately after washing and improving the user experience.

[0050] Below, refer to Figures 1 to 4 Some embodiments of this application will be described in detail.

[0051] Figure 1 Schematic diagram of a drying system provided for some embodiments of this application; Figure 2 Schematic diagrams of drying systems provided for other embodiments of this application; Figure 3 A schematic diagram of a drying system provided for further embodiments of this application; Figure 4 A schematic diagram of a drying system provided for some further embodiments of this application.

[0052] Firstly, such as Figure 1As shown, this application provides a drying system, including: a first drying subsystem including an evaporator 10, a compressor 13, a condenser 11, and a throttling component 12; a second drying subsystem including a moisture absorption and dehumidification device 14 and a regeneration device, wherein the moisture absorption and dehumidification device 14 is used to absorb moisture from the drying air, and the regeneration device is used to regenerate the moisture absorption and dehumidification device 14 that has absorbed moisture; the evaporator 10, the moisture absorption and dehumidification device 14, and the condenser 11 are arranged sequentially along the circulation path of the drying air; the regeneration device includes a cooler 16, which is used to dehumidify the regeneration air, and the regeneration air is used to desorb the moisture absorbed in the moisture absorption and dehumidification device 14; and a valve assembly configured to selectively allow refrigerant to flow from the throttling component 12 through at least one of the evaporator 10 and the cooler 16 to the compressor 13.

[0053] The drying system continuously provides high-temperature drying air to the garment processing equipment, constantly removing moisture from the clothes. The garment processing equipment uses the drying air to pass over the surface of the clothes, heating them and removing evaporated moisture, thus drying them quickly.

[0054] The drying system includes a first drying subsystem and a second drying subsystem. The first drying subsystem is used for dehumidifying and heating the drying air, and the second drying subsystem is used for dehumidifying the drying air.

[0055] The first drying subsystem includes an evaporator 10, a condenser 11, a throttling device 12, and a compressor 13. The compressor 13, condenser 11, and throttling device 12 are connected in series via refrigerant flow paths. There are two refrigerant flow paths between the output of the throttling device 12 and the input of the compressor 13: a first refrigerant flow path 23 and a second refrigerant flow path 24. The evaporator 10 is located in the first refrigerant flow path 23. The refrigerant flows sequentially through the compressor 13, condenser 11, and throttling device 12, and returns from the throttling device 12 to the compressor 13 via at least one of the first refrigerant flow path 23 and the second refrigerant flow path 24, forming a cycle.

[0056] The refrigerant in the evaporator 10 can exchange heat with the drying air, cooling and condensing the air, thereby reducing the humidity in the drying air. The refrigerant in the condenser 11 can exchange heat with the drying air, raising its temperature.

[0057] The second drying subsystem includes a moisture absorption and dehumidification device 14. The moisture absorption and dehumidification device 14 includes an adsorbent capable of absorbing moisture; exemplary adsorbents may be silica gel, alumina, zeolite molecular sieves, and carbon molecular sieves. The moisture absorption and dehumidification device 14 absorbs moisture from the drying air using the adsorbent.

[0058] In the circulation path of the drying air, the evaporator 10, the dehumidification device 14, and the condenser 11 are arranged in sequence. The drying air first passes through the evaporator 10 and is dehumidified for the first time; then it passes through the dehumidification device 14 and is dehumidified for the second time; finally, it passes through the condenser 11 and is heated to a higher temperature, ultimately becoming dry, high-temperature drying air. The dry, high-temperature drying air returns to the evaporator 10 after passing through the material to be dried, thus realizing the circulation of the drying air.

[0059] The second drying subsystem also includes a regeneration device. The regeneration device provides regeneration air to the moisture absorption and dehumidification device 14, which can remove the moisture absorbed by the moisture absorption and dehumidification device 14 from the drying air, thereby regenerating the moisture absorption and dehumidification device 14.

[0060] The regeneration device includes a cooler 16, which is located in the second refrigerant flow path 24. The refrigerant flows sequentially through the compressor 13, the condenser 11, and the throttling device 12, then flows from the throttling device 12 through the second refrigerant flow path 24, through the cooler 16, and back to the compressor 13. The cooler 16 contains a refrigerant pipe for the refrigerant and a regeneration air duct for the regeneration air. The refrigerant pipe and the regeneration air duct are independent of each other, and they exchange heat within the cooler 16. The refrigerant is used to absorb heat from the regeneration air, cooling it and causing condensation, thereby reducing the humidity of the regeneration air.

[0061] The drying system also includes a valve assembly, which is connected to the throttling component 12, the compressor 13, the first refrigerant flow path 23 and the second refrigerant flow path 24 respectively, and is configured to connect at least one of the first refrigerant flow path 23 and the second refrigerant flow path 24.

[0062] When the valve assembly selects the first refrigerant flow path 23 for connection, the evaporator 10, compressor 13, condenser 11, and throttling device 12 are connected in sequence, forming a circulation path from the throttling device 12 back to the evaporator 10. In use, low-temperature, low-pressure gas-liquid two-phase refrigerant flows into the evaporator 10 to absorb heat from the drying air, causing the air to cool and condense. The refrigerant absorbs heat to become a low-temperature, low-pressure gas. The low-temperature, low-pressure gaseous refrigerant flows into the compressor 13 and is compressed into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows into the heating device 15 to release heat from the regeneration air, causing it to heat up. It then flows into the condenser 11 to release heat from the drying air, causing it to heat up. The refrigerant liquefies into a medium-temperature, high-pressure liquid. The medium-temperature, high-pressure liquid refrigerant flows into the throttling device 12, where it is throttled and depressurized into a low-temperature, low-pressure gas-liquid two-phase refrigerant.

[0063] When the valve assembly selects the second refrigerant flow path 24 for connection, the cooler 16, compressor 13, condenser 11, and throttling device 12 are connected in sequence, forming a circulation path from the throttling device 12 back to the cooler 16. In use, low-temperature, low-pressure gas-liquid two-phase refrigerant flows into the cooler 16 to absorb heat from the regeneration air, cooling and condensing it. The refrigerant absorbs heat to become a low-temperature, low-pressure gas. The low-temperature, low-pressure gaseous refrigerant flows into the compressor 13 and is compressed into a high-temperature, high-pressure gaseous refrigerant. The high-temperature, high-pressure gaseous refrigerant flows into the heating device 15 to release heat from the regeneration air, raising its temperature. It then flows into the condenser 11 to release heat from the drying air, raising its temperature. The refrigerant releases heat and liquefies into a medium-temperature, high-pressure liquid. The medium-temperature, high-pressure liquid refrigerant flows into the throttling device 12, where it is throttled and depressurized into a low-temperature, low-pressure gas-liquid two-phase refrigerant.

[0064] Because the system includes an evaporator 10 and a dehumidification device 14, and the drying air passes through the evaporator 10 first and then the dehumidification device 14, the high-humidity drying air undergoes a first dehumidification process in the evaporator 10, reducing its humidity. It then undergoes a second dehumidification process in the dehumidification device 14, further reducing its humidity. This lower humidity allows the drying air to carry more moisture from the items being dried, thus increasing the drying speed. Furthermore, the dehumidification device 14 is suitable for dehumidifying low-humidity drying air, ensuring the drying system maintains good dehumidification performance even in later stages of use. Since the evaporator 10, dehumidification device 14, and condenser 11 are arranged sequentially along the air circulation path, a continuous supply of dry, high-temperature drying air is provided. Because a cooler 16 is provided for dehumidifying the regenerated air, the regenerated air can remove moisture from the dehumidification device 14, maintaining its effective adsorption of moisture from the drying air. Because the valve assembly can selectively connect to the evaporator 10 and / or the cooler 16, all the cooling capacity of the refrigerant can be supplied to the evaporator 10, or all of it to the cooler 16, or both. This allows the drying system to switch modes according to actual conditions, helping to reduce energy consumption and improve drying efficiency and effect. Since the cooler 16 can be connected to the throttling component 12, there is no need for an additional dehumidification device to regenerate the moisture absorption and dehumidification device 14, and it also reduces the cooling capacity loss at the cold end of the throttling component 12, resulting in greater energy savings.

[0065] In some embodiments, such as Figure 2 and Figure 4 As shown, the valve assembly includes a reversing valve 21 and an on / off valve 22. The throttling component 12 and the compressor 13 are switched to be connected via the evaporator 10 or the cooler 16 through the reversing valve 21. The evaporator 10 and the cooler 16 are switched on and off through the on / off valve 22.

[0066] The valve assembly includes a reversing valve 21, which can be switched to be connected to the first refrigerant flow path 23 or to be connected to the second refrigerant flow path 24. When the reversing valve 21 is switched to be connected to the first refrigerant flow path 23, the evaporator 10 located in the first refrigerant flow path 23 is connected to the throttling component 12 and the compressor 13 respectively; when the reversing valve 21 is switched to be connected to the second refrigerant flow path 24, the cooler 16 located in the second refrigerant flow path 24 is connected to the throttling component 12 and the compressor 13 respectively.

[0067] A reversing valve 21 can be positioned between the first refrigerant flow path 23 and the second refrigerant flow path 24, and connected to both paths respectively. Specifically, the reversing valve 21 can be connected to the throttling component 12, the first refrigerant flow path 23, and the second refrigerant flow path 24, or it can be connected to the compressor 13, the first refrigerant flow path 23, and the second refrigerant flow path 24. Alternatively, two reversing valves 21 can be provided: one connected to the throttling component 12, the first refrigerant flow path 23, and the second refrigerant flow path 24; the other connected to the compressor 13, the first refrigerant flow path 23, and the second refrigerant flow path 24.

[0068] like Figure 2 As shown, the valve assembly also includes an on / off valve 22, which can be connected to the evaporator 10 and the cooler 16 via a connecting pipe. A connecting pipe can also be provided between the first refrigerant flow path 23 and the second refrigerant flow path 24, allowing the evaporator 10 and the cooler 16 to be connected. The on / off valve 22 can be located on the connecting pipe and can control the opening and closing of the connecting pipe, thereby achieving the on / off connection between the evaporator 10 and the cooler 16.

[0069] In a specific embodiment, such as Figure 3 As shown, the evaporator 10 and the cooler 16 are connected by a connecting pipe. A reversing valve 21 is connected to the throttling component 12, the first refrigerant flow path 23, and the second refrigerant flow path 24, respectively. Two on / off valves 22 are provided. One end of the first refrigerant flow path 23 is connected to the reversing valve 21, and an on / off valve 22 is installed on the first refrigerant flow path 23 located between the evaporator 10 and the compressor 13. One end of the second refrigerant flow path 24 is connected to the reversing valve 21, and another on / off valve 22 is installed on the second refrigerant flow path 24 located between the cooler 16 and the compressor 13.

[0070] Optionally, the reversing valve 21 is connected to the compressor 13, the first refrigerant flow path 23, and the second refrigerant flow path 24. One end of the first refrigerant flow path 23 is connected to the reversing valve 21, and an on / off valve 22 is installed on the first refrigerant flow path 23 located between the evaporator 10 and the throttling component 12. One end of the second refrigerant flow path 24 is connected to the reversing valve 21, and another on / off valve 22 is installed on the second refrigerant flow path 24 located between the cooler 16 and the throttling component 12.

[0071] Therefore, by controlling the reversing valve 21, the throttling component 12 can be connected to the evaporator 10 or the cooler 16; by controlling the on / off valve 22, the on / off of the evaporator 10 and the cooler 16 can be controlled, allowing the refrigerant to switch between four modes: passing only through the evaporator 10, passing through the evaporator 10 first and then through the cooler 16, passing through the cooler 16 first and then through the evaporator 10, and passing only through the cooler 16. This allows the drying system to switch modes according to actual conditions, which helps to reduce energy consumption and improve drying efficiency and drying effect.

[0072] In some embodiments, such as Figure 2 and Figure 4 As shown, with the on / off valve 22 connecting the evaporator 10 and the cooler 16, the throttling component 12 is switched to be connected to one of the evaporator 10 and the cooler 16 via the reversing valve 21, and the compressor 13 is switched to be connected to the other of the evaporator 10 and the cooler 16 via the reversing valve 21.

[0073] Two reversing valves 21 are provided. One reversing valve 21 is connected to the throttling component 12, the evaporator 10 and the cooler 16 respectively; the other reversing valve 21 is connected to the compressor 13, the evaporator 10 and the cooler 16 respectively. The evaporator 10 and the cooler 16 are connected by a connecting pipe, and an on / off valve 22 is provided on the connecting pipe to control the opening and closing of the connecting pipe.

[0074] Open the on / off valve 22 to connect the evaporator 10 and the cooler 16. Control the reversing valve 21 so that one reversing valve 21 connects the throttling component 12 and the evaporator 10, and the other reversing valve 21 connects the compressor 13 and the cooler 16. At this time, the throttling component 12, the evaporator 10, the cooler 16, the compressor 13, and the condenser 11 are connected in series. The low-temperature, low-pressure gas-liquid two-phase refrigerant flowing out of the throttling component 12 first passes through the evaporator 10 to provide cooling to the drying air, and then flows through the cooler 16 to provide cooling to the regeneration air. The refrigerant itself absorbs heat and vaporizes into low-temperature, low-pressure gas step by step.

[0075] Open the on / off valve 22 to connect the evaporator 10 and the cooler 16. Control the reversing valve 21 so that one reversing valve 21 connects the throttling component 12 and the cooler 16, and the other reversing valve 21 connects the compressor 13 and the evaporator 10. At this time, the throttling component 12, the cooler 16, the evaporator 10, the compressor 13, and the condenser 11 are connected in series. The low-temperature, low-pressure gas-liquid two-phase refrigerant flowing out from the throttling component 12 first passes through the cooler 16 to provide cooling for the regeneration air, and then passes through the evaporator 10 to provide cooling for the drying air. The refrigerant itself absorbs heat and vaporizes into low-temperature, low-pressure gas step by step.

[0076] Therefore, when the throttling component 12 is connected to the evaporator 10 and the compressor 13 is connected to the cooler 16, the refrigerant passes through the evaporator 10 first and then the cooler 16, thus improving the condensation effect of the evaporator 10 and enhancing the drying capacity of the first drying system. The first drying system can be used as the main drying system and the second drying system as the auxiliary drying system. When the throttling component 12 is connected to the cooler 16 and the compressor 13 is connected to the evaporator 10, the refrigerant passes through the cooler 16 first and then the evaporator 10, thus improving the condensation effect of the cooler 16 and enhancing the drying capacity of the second drying system. The second drying system can be used as the main drying system and the first drying system as the auxiliary drying system.

[0077] In some embodiments, see continue to see Figure 2 and Figure 4 When the on / off valve 22 disconnects the evaporator 10 and the cooler 16, the throttling component 12 switches to be connected to one of the evaporator 10 and the cooler 16 via the reversing valve 21, and the compressor 13 switches to be connected to the same one of the evaporator 10 and the cooler 16 via the reversing valve 21.

[0078] Close the on / off valve 22 to make the evaporator 10 and the cooler 16 relatively independent. Control the reversing valves 21 so that one reversing valve 21 connects the throttling component 12 and the evaporator 10, and the other reversing valve 21 connects the compressor 13 and the evaporator 10. At this time, the throttling component 12, the evaporator 10, the compressor 13, and the condenser 11 are connected in series. The low-temperature, low-pressure gas-liquid two-phase refrigerant flowing out from the throttling component 12 only passes through the evaporator 10 and not through the cooler 16, providing cooling capacity to the drying air. In this mode, the dehumidification device 14 has a strong adsorption effect initially, but the adsorption effect decreases over time, and more cooling capacity is used to provide cooling capacity to the evaporator 10, which is mainly responsible for dehumidification.

[0079] Close the on / off valve 22 to make the evaporator 10 and cooler 16 relatively independent. Control the reversing valves 21 so that one reversing valve 21 connects the throttling component 12 and cooler 16, and the other reversing valve 21 connects the compressor 13 and cooler 16. At this time, the throttling component 12, cooler 16, compressor 13, and condenser 11 are connected in series. The low-temperature, low-pressure gas-liquid two-phase refrigerant flowing out from the throttling component 12 only passes through the cooler 16 and not the evaporator 10, providing cooling capacity to the regeneration air. In this mode, more cooling capacity is used to provide cooling capacity to the cooler 16, so that the regeneration air can be kept dry. The dehumidification device 14 is regenerated by the regeneration air, thereby continuously adsorbing moisture in the drying air.

[0080] Therefore, when the throttling component 12 is connected to the evaporator 10 and the compressor 13 is connected to the evaporator 10, the cooling capacity of the refrigerant is only provided to the evaporator 10, which is suitable for situations where the humidity of the drying air is high. The evaporator 10 can efficiently reduce the humidity of the drying air to a certain level. When the throttling component 12 is connected to the cooler 16 and the compressor 13 is connected to the cooler 16, the cooling capacity of the refrigerant is only provided to the cooler 16, which is suitable for situations where the humidity of the drying air is low. The moisture absorption and dehumidification device 14 can efficiently adsorb the residual water vapor in the drying air.

[0081] In some embodiments, such as Figure 4 As shown, the inlet of the reversing valve 21 is connected to the refrigerant output end of the throttling component 12, the first outlet of the reversing valve 21 is connected to the refrigerant input end of the evaporator 10, and the second outlet is connected to the refrigerant input end of the cooler 16. The refrigerant output ends of the evaporator 10 and the cooler 16 are both connected to the refrigerant input end of the compressor 13. The refrigerant output ends of the evaporator 10 and the refrigerant input ends of the cooler 16 are connected in series through the first connecting pipe 25, and the refrigerant output ends of the cooler 16 and the refrigerant input ends of the evaporator 10 are connected in series through the second connecting pipe 26. The on / off valve 22 includes a first on / off valve 221 disposed in the first connecting pipe 25 and a second on / off valve 222 disposed in the second connecting pipe 26. The reversing valve 21 is configured to connect the inlet to the first outlet or the second outlet.

[0082] The reversing valve 21 has one inlet and two outlets, designated as the first outlet and the second outlet. Each switch of the reversing valve 21 connects the inlet to either the first or the second outlet. The refrigerant inlet of the throttling element 12 is connected to the refrigerant outlet of the condenser 11, and the refrigerant outlet of the throttling element 12 is connected to the inlet of the reversing valve 21. The refrigerant inlet of the evaporator 10 is connected to the first outlet, and the refrigerant outlet of the evaporator 10 is connected to the refrigerant inlet of the compressor 13. The refrigerant inlet of the cooler 16 is connected to the second outlet, and the refrigerant outlet of the cooler 16 is connected to the refrigerant inlet of the compressor 13. The refrigerant outlet of the compressor 13 is connected to the refrigerant inlet of the condenser 11.

[0083] Two connecting pipes, designated as the first connecting pipe and the second connecting pipe, are installed between the evaporator 10 and the cooler 16. The refrigerant output terminal of the evaporator 10 is connected in series with the refrigerant input terminal of the cooler 16 via the first connecting pipe, and the refrigerant output terminal of the cooler 16 is connected in series with the refrigerant input terminal of the evaporator 10 via the second connecting pipe. Two on / off valves 22 are installed, designated as the first on / off valve 221 and the second on / off valve 222. The first on / off valve 221 is installed on the first connecting pipe, and the second on / off valve 222 is installed on the second connecting pipe.

[0084] Furthermore, the third outlet of the reversing valve 21 is connected to the refrigerant input end of the compressor 13, the first inlet of the reversing valve 21 is connected to the refrigerant output end of the evaporator 10, the second inlet is connected to the refrigerant input end of the cooler 16, and the refrigerant output ends of the evaporator 10 and the cooler 16 are both connected to the refrigerant input end of the compressor 13. The reversing valve 21 is configured to connect the third outlet with the first inlet or the second inlet.

[0085] Therefore, by controlling the reversing valve 21, the throttling component 12 can be connected to the evaporator 10 or the cooler 16. By controlling the first on / off valve 221 and the second on / off valve 222, the evaporator 10 and the cooler 16 can be connected or disconnected. The order in which the refrigerant flows through the evaporator 10 and the cooler 16 can also be changed, allowing the refrigerant to switch between four modes: only through the evaporator 10, first through the evaporator 10 and then through the cooler 16, first through the cooler 16 and then through the evaporator 10, and only through the cooler 16. This allows the drying system to switch modes according to actual conditions, helping to reduce energy consumption and improve drying efficiency and effect.

[0086] In some embodiments, when the first on / off valve 221 and the second on / off valve 222 both disconnect the flow in the first connecting pipe 25 and the second connecting pipe 26, the reversing valve 21 selects to allow the refrigerant to flow from the throttling component 12 through the evaporator 10 or the cooler 16 to the compressor 13 by reversing.

[0087] By closing the first shut-off valve 221 and the second shut-off valve 222, the flow in the first connecting pipe 25 and the second connecting pipe 26 is cut off, thereby making the evaporator 10 and the cooler 16, as well as the first refrigerant flow path 23 and the second refrigerant flow path 24, relatively independent.

[0088] When the reversing valve 21 switches to the first refrigerant flow path 23, the refrigerant flows out from the throttling component 12, passes only through the evaporator 10, and then enters the compressor 13.

[0089] This mode can be used at the beginning of the drying process. In this mode, the first drying subsystem and the dehumidification device 14 work together to dehumidify, and the dehumidification device 14 does not need to be regenerated at the beginning of operation, so the cooling capacity is mainly provided to the evaporator 10. Furthermore, at the beginning of drying, the drying air carries more moisture, and the evaporator 10 has a better dehumidification capacity for air with higher humidity than the dehumidification device 14.

[0090] When the reversing valve 21 switches to the second refrigerant flow path 24, the refrigerant flows out from the throttling component 12, passes only through the cooler 16, and then enters the compressor 13.

[0091] This mode can be used after drying is complete. In this mode, the drying air circulation can be stopped, and the regeneration air regenerates the adsorption medium in the moisture absorption and dehumidification device 14, restoring all adsorption media to a state with a strong adsorption rate. This ensures that efficient dehumidification can be achieved from the initial startup the next time it is used.

[0092] This mode can also be used when the humidity is low. The dehumidification device 14 has a better adsorption capacity for air with low humidity than the evaporator 10.

[0093] Therefore, when the reversing valve 21 is connected to the evaporator 10, the cooling capacity of the refrigerant is only provided to the evaporator 10, which is suitable for situations where the humidity of the drying air is high. The evaporator 10 can efficiently reduce the humidity of the drying air to a certain level. When the reversing valve 21 is connected to the cooler 16, the cooling capacity of the refrigerant is only provided to the cooler 16, which is suitable for situations where the humidity of the drying air is low. The moisture absorption and dehumidification device 14 can efficiently adsorb the residual water vapor in the drying air.

[0094] In some embodiments, such as Figure 4 As shown, the reversing valve 21 connects the evaporator 10 to the throttling component 12 and the cooler 16 to the compressor 13, and the first on / off valve 221 connects the evaporator 10 and the cooler 16 through the first connecting pipe 25; or, the reversing valve 21 connects the cooler 16 to the throttling component 12 and the evaporator 10 to the compressor 13, and the second on / off valve 222 connects the evaporator 10 and the cooler 16 through the second connecting pipe 26.

[0095] The reversing valve 21 switches to connect the throttling component 12 to the evaporator 10 and the compressor 13 to the cooler 16. The second on-off valve 222 closes, and the first on-off valve 221 opens, allowing refrigerant to flow from the evaporator 10 into the first connecting pipe 25 of the cooler 16. The refrigerant flowing out of the throttling component 12 passes sequentially through the evaporator 10 and the cooler 16 before entering the compressor 13. This mode can be used after drying has been in progress for a period of time. In this mode, the evaporator 10 receives more cooling from the refrigerant than the cooler 16, making it suitable for dehumidifying air with high humidity.

[0096] The reversing valve 21 switches to connect the throttling component 12 to the cooler 16 and the compressor 13 to the evaporator 10. The first on-off valve 221 is closed, and the second on-off valve 222 is opened, allowing the refrigerant to flow from the cooler 16 into the second connecting pipe 26 of the evaporator 10. The refrigerant flowing out of the throttling component 12 passes sequentially through the cooler 16 and the evaporator 10, and then enters the compressor 13. This mode can be adopted after the above-mentioned mode of refrigerant first passing through the evaporator 10 and then through the cooler 16 has been used for a period of time. In this mode, the cooling capacity obtained by the cooler 16 from the refrigerant is greater than that obtained by the evaporator 10 from the refrigerant, which is suitable for dehumidifying air with low humidity.

[0097] Therefore, when the throttling component 12 is connected to the evaporator 10 and the compressor 13 is connected to the cooler 16, the refrigerant passes through the evaporator 10 first and then the cooler 16, thus improving the condensation effect of the evaporator 10 and enhancing the drying capacity of the first drying system. The first drying system can be used as the main drying system and the second drying system as the auxiliary drying system. When the throttling component 12 is connected to the cooler 16 and the compressor 13 is connected to the evaporator 10, the refrigerant passes through the cooler 16 first and then the evaporator 10, thus improving the condensation effect of the cooler 16 and enhancing the drying capacity of the second drying system. The second drying system can be used as the main drying system and the first drying system as the auxiliary drying system.

[0098] In some embodiments, such as Figures 1 to 4 As shown, the regeneration device also includes a heating device 15, which is used to heat the regeneration air. The refrigerant flow path is connected in series with the compressor 13, the heating device 15, the condenser 11 and the throttling component 12. Along the circulation path of the regeneration air, the cooler 16, the heating device 15 and the moisture absorption and dehumidification device 14 are arranged in sequence.

[0099] The regeneration device also includes a heating device 15, which is connected to the refrigerant flow path and communicates with the heat output terminal of the compressor 13. The refrigerant flows sequentially through the compressor 13, the heating device 15, the condenser 11, and the throttling component 12. The heating device 15 has a refrigerant pipe for passing the refrigerant and a regeneration air duct for passing the regeneration air. The refrigerant pipe and the regeneration air duct are independent of each other, and they exchange heat within the heating device 15. The refrigerant is used to release heat to the regeneration air, thereby raising the temperature of the regeneration air.

[0100] Because a heating device 15 is provided to heat the regeneration air, the regeneration air can remove a significant amount of moisture from the dehumidification device 14, maintaining the dehumidification device 14's adsorption effect on the moisture in the drying air. Since the heating device 15 is connected to the compressor 13 via a refrigerant flow path, there is no need for an additional electric heating device to regenerate the dehumidification device 14. This reduces heat loss at the hot end of the compressor 13, resulting in greater energy savings; it also prevents the heat generated by the electric heating device from affecting the heat pump system.

[0101] In some embodiments, along the refrigerant circulation path, the heating device 15 is connected downstream of the compressor 13 and upstream of the condenser 11 to exchange heat with the refrigerant compressed by the compressor 13 and the regeneration air.

[0102] The heating device 15 is connected downstream of the compressor 13 and upstream of the condenser 11. The refrigerant flows sequentially through the compressor 13, the heating device 15, the condenser 11, and the throttling device 12. The heating device 15 contains a refrigerant pipe for the refrigerant and a regeneration air duct for the regeneration air. The refrigerant pipe and the regeneration air duct are independent of each other, and they exchange heat within the heating device 15. The refrigerant is used to release heat to the regeneration air, thus raising its temperature.

[0103] In the circulation path of the regenerated air, the dehumidification device 14, the cooler 16, and the heating device 15 are arranged sequentially. The regenerated air first passes through the dehumidification device 14, which carries away the water inside; then it passes through the cooler 16 and is dehumidified; finally, it passes through the heating device 15 and is heated to become dry, high-temperature regenerated air. The regenerated air is then circulated through the dehumidification device 14 to achieve the circulation of the regenerated air.

[0104] As a result, the high-temperature refrigerant flowing out of the compressor 13 flows into the heating device 15, enabling the heating device 15 to exchange heat with the regeneration air, thereby raising the temperature of the regeneration air. This helps to improve the adsorption efficiency of the regeneration air on the moisture in the dehumidification device 14 and accelerates the regeneration of the dehumidification device 14.

[0105] In some embodiments, the dehumidification device 14 includes a rotating mechanism and a dehumidification component. The rotating mechanism is configured to drive the dehumidification component to rotate through a dehumidification zone and a regeneration zone. The dehumidification zone is located in the circulation path of the drying air, and the regeneration zone is located in the circulation path of the regeneration air.

[0106] The moisture absorption zone is located in the circulation path of the drying air. In the moisture absorption zone, the moisture absorption and dehumidification components can absorb moisture from the drying air. The regeneration zone is located in the circulation path of the regeneration air. In the regeneration zone, the moisture in the moisture absorption and dehumidification components can be desorbed by the regeneration air.

[0107] Along the circulation path of the drying air, the moisture absorption zone can be located between the evaporator 10 and the condenser 11. Along the circulation path of the regeneration air, the regeneration zone is located downstream of the heating device 15.

[0108] In some embodiments, the desiccant assembly can be a desiccant disc, which can be a honeycomb or corrugated disc carrying a desiccant, capable of adsorbing and desorbing absorbed water vapor to achieve repeated desorption and regeneration. In some embodiments, the desiccant disc can include an inorganic / organic fiber carrier (such as ceramics, glass fibers, MOFs, COFs, cordierite, etc.), coated with a desiccant such as a molecular sieve, which is uniformly distributed between and on the surface of the fiber carrier to achieve adsorption of moisture in the airflow. The desiccant can be, for example, zeolite, modified / synthetic zeolite, molecular sieves (including but not limited to single-crystal or mixed-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), polymeric desiccant, alkali metal aluminosilicates (13X molecular sieves), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with hygroscopic properties.

[0109] Regarding the rotating mechanism, for example, it may include a rotary motor and a rotating shaft. The rotating shaft is connected to the output end of the rotary motor and to the moisture absorption and dehumidification component (e.g., the center of the dehumidification turntable), and drives the moisture absorption and dehumidification component to rotate around the rotating shaft.

[0110] Therefore, by rotating the moisture-absorbing and dehumidifying component, repeated moisture absorption and regeneration of the component can be achieved. Moreover, dehumidification and regeneration are carried out in two separate areas, allowing the regeneration air and drying air to circulate independently. This enables the moisture-absorbing and dehumidifying component to be regenerated while clothes are being dried, which helps to improve the drying speed.

[0111] In some embodiments, the moisture absorption and dehumidification component includes a breathable porous structure, the material of which is zeolite, lithium chloride, silica gel, modified silica gel, or molecular sieve.

[0112] Therefore, moisture adsorption and desorption can be achieved easily and effectively. The moisture absorption and dehumidification components are reusable and have low cost.

[0113] In some embodiments, such as Figures 2 to 4 As shown, the drying system also includes a drying cylinder 17, which is used to carry the items to be dried. Along the circulation path of the drying air, the evaporator 10, the dehumidification device 14, the condenser 11, and the drying cylinder 17 are arranged in sequence. The evaporator 10 is used to dehumidify the drying air, and the condenser 11 is used to heat the dehumidified drying air.

[0114] The drying air passes through the condenser 11 and enters the drying cylinder 17. It passes through the material to be dried in the drying cylinder 17, leaves the drying cylinder 17 and goes to the evaporator 10. Then, starting from the evaporator 10, it passes through the moisture absorption and dehumidification device 14 and the condenser 11 in sequence, and finally returns to the drying cylinder 17 to continue the cycle.

[0115] This provides a place to store the items to be dried, and the drying air passes through the drying cylinder 17 to dry the items.

[0116] In some embodiments, see continue to see Figures 2 to 4 The drying system also includes a filter screen 18. Along the circulation path of the drying air, the evaporator 10, the moisture absorption and dehumidification device 14, the condenser 11, the drying cylinder 17, and the filter screen 18 are arranged in sequence.

[0117] The filter 18 is disposed on the circulation path of the drying air between the drying cylinder 17 and the evaporator 10. The filter 18 can be disposed in the channel through which the drying air leaves the drying cylinder 17, or at the connection interface between the drying cylinder 17 and the channel through which the drying air flows. Optionally, the filter 18 can be detached and installed.

[0118] Therefore, the drying air leaving the drying cylinder 17 is filtered by the filter screen 18 before entering the circulation path starting with the evaporator 10, which helps to reduce the probability of debris clogging the circulation path.

[0119] In some embodiments, the drying system further includes a first fan 19 located in the circulation path of the drying air, the first fan 19 providing circulation power for the drying air; the drying system further includes a second fan 20 located in the circulation path of the regeneration air, the second fan 20 providing circulation power for the regeneration air.

[0120] Thus, the drying air can circulate under the drive of the first fan 19, and the regeneration air can circulate under the drive of the second fan 20, thereby enabling rapid and effective drying and desorption.

[0121] The second aspect of this application provides a garment processing device, including the drying system provided in the first aspect above.

[0122] Because clothing processing equipment includes a drying system that can provide drying air with low humidity and switch modes, it can adapt to diverse usage needs, has strong flexibility, and can quickly and efficiently dry the clothes to be dried, reducing user waiting time and improving the user experience.

[0123] In some embodiments, the clothing handling equipment includes a dryer or a washer-dryer combo.

[0124] Therefore, it can quickly and efficiently dry clothes after washing, allowing users to use them immediately after washing and improving the user experience.
