[0002] In the prior art, clothes treatment equipment usually uses a heat pump system to dry clothes, and the heat pump system usually includes an evaporator, a condenser, a compressor, a throttling component, etc.

[0003] 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 dry drying air to the clothes to be dried.

[0004] However, the existing clothes treatment equipment still has low drying efficiency. How to improve the drying efficiency is one of the research topics in the industry. Invention content

[0005] To solve the above technical problems, the embodiments of the present application add a moisture adsorption and dehumidification device to the traditional heat pump system, and a part of the refrigerant compressed by the compressor is led out and used to regenerate the moisture adsorption and dehumidification device, the evaporator and the moisture adsorption and dehumidification device jointly dehumidify, so that the humidity of the drying air can be lower, thereby improving the drying efficiency and shortening the drying time, and without the need for additional electric heating devices for regenerating the moisture adsorption and dehumidification device, both the heat loss of the hot end of the compressor and the heat generated by the electric heating device can be avoided.

[0006] The first aspect of the present application provides a drying system, comprising: a first drying subsystem including an evaporator, a condenser, a throttling component and a compressor connected by a refrigerant flow path; a second drying subsystem including a moisture adsorption and dehumidification device and a regeneration device, the moisture adsorption and dehumidification device is used to adsorb water vapor in drying air, and the regeneration device is used to regenerate the moisture adsorption and dehumidification device adsorbed with water vapor; along the circulation path of the drying air, the evaporator, the moisture adsorption and dehumidification device, and the condenser are arranged in sequence, the regeneration device includes a heating device, the heating device is used to heat regeneration air, the regeneration air is used to desorb the moisture adsorbed in the moisture adsorption and dehumidification device, and along the circulation path of the refrigerant, the heating device is connected to the downstream side of the compressor and the upstream side of the condenser.

[0007] The evaporator and the moisture absorption and removal device are arranged, and the drying air first passes through the evaporator and then passes through the moisture absorption and removal device. Therefore, the drying air with high humidity first passes through the evaporator to be dehumidified for the first time, and the humidity of the drying air is reduced. Then, the drying air passes through the moisture absorption and removal device to be dehumidified for the second time, and the humidity of the drying air is further reduced. The drying air with lower humidity can carry more water from the objects to be dried, so that the drying speed can be improved. In addition, the moisture absorption and removal device can be used to dehumidify the drying air with lower humidity, so that the drying system still has good dehumidification effect in the later stage of use. The evaporator, the moisture absorption and removal device, and the condenser are arranged in sequence along the circulation path of the drying air, so that dry and high-temperature drying air can be continuously provided. The heating device for heating the regeneration air is arranged, so that the regeneration air can carry away the water in the moisture absorption and removal device, and the adsorption effect of the moisture absorption and removal device on the water in the drying air can be maintained. The heating device is connected to the downstream side of the compressor and the upstream side of the condenser, so that the high-temperature refrigerant flowing out of the compressor flows into the heating device. The heating device can exchange heat with the regeneration air, so that the regeneration air is heated. The electric heating device for regenerating the moisture absorption and removal device does not need to be additionally arranged, the heat loss of the hot end of the compressor can be reduced, and the energy consumption is further reduced. In addition, the electric heating device does not affect the heat pump system.

[0008] In some embodiments, the regeneration device further comprises a cooler for dehumidifying the regeneration air, and the cooler is connected to the evaporator through the refrigerant flow path. Along the circulation path of the regeneration air, the cooler, the heating device, and the moisture absorption and removal device are arranged in sequence.

[0009] Therefore, the cooler can condense the water vapor in the regeneration air, and continuously provide the moisture absorption and removal device with regeneration air with low humidity, so that the moisture absorption and removal device can be stably regenerated, and the dehumidification capacity and efficiency of the moisture absorption and removal device can be maintained.

[0010] In some embodiments, along the circulation path of the refrigerant, the compressor, the heating device, the condenser, the throttling component, the evaporator, and the cooler are arranged in sequence.

[0012] In some embodiments, along the circulation path of the refrigerant, the compressor, the heating device, the condenser, the throttling component, the cooler, and the evaporator are arranged in sequence.

[0016] In some embodiments, the second drying subsystem further comprises a second water receiving tray arranged below the cooler in the direction of gravity, for receiving the condensed water condensed on the surface of the cooler.

[0017] In this way, the second water receiving tray collects the condensed water condensed on the cooler, which facilitates subsequent centralized treatment of the condensed water.

[0018] In some embodiments, the moisture absorbing and dehumidifying device comprises a rotating mechanism and a moisture absorbing and dehumidifying assembly, the rotating mechanism is configured to drive the moisture absorbing and dehumidifying assembly to rotate through a moisture absorbing area and a regeneration area, the moisture absorbing area is located in the circulation path of the drying air, and the regeneration area is located in the circulation path of the regeneration air.

[0019] In this way, repeated moisture absorption and regeneration of the moisture absorbing and dehumidifying assembly can be achieved by rotating the moisture absorbing and dehumidifying assembly; and since dehumidification and regeneration are respectively performed in the two areas, the regeneration air and the drying air can be independently circulated, the regeneration of the moisture absorbing and dehumidifying assembly can be performed while the clothes are dried, which is conducive to improving the drying speed.

[0020] In some embodiments, the moisture absorbing and dehumidifying assembly comprises a gas-permeable porous structure, and the material of the gas-permeable porous structure is zeolite, lithium chloride, silica gel, modified silica gel or molecular sieve.

[0021] In this way, the adsorption and desorption of moisture can be easily and effectively achieved. The moisture absorbing and dehumidifying assembly can be reused, and the cost is relatively low.

[0022] In some embodiments, the drying system further comprises a drying drum for carrying the objects to be dried, and the evaporator, the moisture absorbing and dehumidifying device, the condenser and the drying drum are arranged in sequence along the circulation path of the drying air, wherein the evaporator is configured to dehumidify the drying air, and the condenser is configured to heat the dehumidified drying air.

[0023] Thus, a storage place is provided for the to-be-dried objects, and the drying air is used to dry the to-be-dried objects.

[0024] In some embodiments, the drying system further comprises a filter screen, and the evaporator, the dehumidification device, the condenser, the drying cylinder and the filter screen are arranged in sequence along a circulation path of the drying air.

[0025] Thus, the drying air that has left the drying cylinder is filtered by the filter screen before entering the circulation path starting from the evaporator, which helps to reduce the probability of the circulation path being blocked by sundries.

[0045] Next, the embodiments of the present application will be described with reference to the accompanying drawings. Figures 1 to 2 The embodiments of the present application will be described in detail.

[0046] Figure 1 The schematic diagram of the drying system provided for some embodiments of the present application is shown in the figure. Figure 2 The schematic diagram of the drying system provided for some embodiments of the present application is shown in the figure.

[0047] In a first aspect, as Figure 1 and Figure 2As shown, the embodiment of the present application provides a drying system, which comprises: a first drying subsystem comprising an evaporator 10, a condenser 11, a throttling component 12 and a compressor 13 connected by a refrigerant flow path; a second drying subsystem comprising a moisture adsorption and removal device 14 and a regeneration device, the moisture adsorption and removal device 14 being used for adsorbing water vapor in drying air, and the regeneration device being used for regenerating the moisture adsorption and removal device 14 adsorbed with water vapor; along a circulating path of the drying air, the evaporator 10, the moisture adsorption and removal device 14 and the condenser 11 are arranged in sequence, and the regeneration device comprises a heating device 15, the heating device 15 being used for heating regeneration air, and the regeneration air being used for desorbing water adsorbed in the moisture adsorption and removal device 14, along a circulating path of the refrigerant, the heating device 15 is connected to a downstream side of the compressor 13 and an upstream side of the condenser 11.

[0048] The drying system can continuously provide high-temperature dry drying air for the clothes treatment device, so that the water on the to-be-dried object is continuously taken away. The clothes treatment device uses the drying air to pass through the surface of the to-be-dried object, heats the to-be-dried object and takes away the evaporated water, so that the to-be-dried object is quickly dried.

[0049] The drying system comprises 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.

[0050] The first drying subsystem comprises the evaporator 10, the condenser 11, the throttling component 12 and the compressor 13. The evaporator 10, the condenser 11, the throttling component 12 and the compressor 13 are connected to each other in series by a refrigerant flow path. The refrigerant flow path flows through the evaporator 10, the compressor 13, the condenser 11 and the throttling component 12 in sequence, and returns to the evaporator 10 from the throttling component 12 to form a circulating refrigerant flow path.

[0051] The refrigerant in the evaporator 10 can exchange heat with the drying air, so that the drying air is cooled and condensed, thereby reducing the humidity of the drying air. The refrigerant in the condenser 11 can exchange heat with the drying air, so that the drying air is heated.

[0052] The second drying subsystem comprises the moisture adsorption and removal device 14. The moisture adsorption and removal device 14 comprises an adsorbent capable of adsorbing water, and the adsorbent can be silica gel, alumina, zeolite molecular sieve and carbon molecular sieve, for example. The moisture adsorption and removal device 14 adsorbs the water in the drying air through the adsorbent.

[0053] Along the circulating path of the drying air, the evaporator 10, the moisture adsorption and removal 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 passes through the moisture adsorption and removal device 14 and is dehumidified for the second time; and finally passes through the condenser 11 and is heated to rise in temperature, and finally becomes dry and high-temperature drying air. The dry and high-temperature drying air returns to the evaporator 10 after passing through the to-be-dried object, realizing the circulation of the drying air.

[0054] The second drying subsystem further comprises a regenerating device. The regenerating device provides a regenerating air to the moisture adsorption and removal device 14, which can take away the water vapor adsorbed by the moisture adsorption and removal device 14 from the drying air, so as to regenerate the moisture adsorption and removal device 14.

[0055] The regenerating device comprises a heating device 15, which is connected in the refrigerant flow path, downstream of the compressor 13 and upstream of the condenser 11. The refrigerant flow path sequentially flows through the evaporator 10, the compressor 13, the heating device 15, the condenser 11 and the throttling component 12, and returns to the evaporator 10 from the throttling component 12 to form a circulating refrigerant flow path. The heating device 15 is provided with a refrigerant pipe through which the refrigerant passes and a regenerating air pipe through which the regenerating air passes. The refrigerant pipe and the regenerating air pipe are independent of each other, and heat exchange is performed between the two in the heating device 15. The refrigerant is used to release heat to the regenerating air, so as to heat the regenerating air.

[0056] In use, the low-temperature and low-pressure gas-liquid two-phase refrigerant flows into the evaporator 10, which is used to absorb heat from the drying air, so as to cool and condense the drying air, and the refrigerant absorbs heat to become low-temperature and low-pressure gas. The low-temperature and low-pressure gaseous refrigerant flows into the compressor 13, which is compressed into high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant flows into the heating device 15, which is used to release heat to the regenerating air, so as to heat the regenerating air. Then, the regenerating air flows into the condenser 11, which is used to release heat to the drying air, so as to heat the drying air, and the refrigerant releases heat to be liquefied into medium-temperature and high-pressure liquid. The medium-temperature and high-pressure liquid-phase refrigerant flows into the throttling component 12, which is throttled and decompressed into low-temperature and low-pressure gas-liquid two-phase refrigerant.

[0057] Due to the evaporator 10 and the moisture absorption and dehumidification device 14, and the drying air first passes through the evaporator 10 and then passes through the moisture absorption and dehumidification device 14, so the drying air with high humidity first passes through the evaporator 10 for the first dehumidification, and the humidity of the drying air is reduced, and then the drying air passes through the moisture absorption and dehumidification device 14 for the second dehumidification, and the humidity of the drying air is reduced to a lower value. The drying air with lower humidity can carry more water from the drying object, thereby improving the drying speed. Moreover, the moisture absorption and dehumidification device 14 can be suitable for dehumidifying the drying air with lower humidity, so that the drying system still has good dehumidification effect in the later stage of use. Since the evaporator 10, the moisture absorption and dehumidification device 14, and the condenser 11 are arranged in sequence along the circulation path of the drying air, dry and high-temperature drying air can be continuously provided. Due to the heating device 15 for heating the regeneration air, the regeneration air can carry away the water in the moisture absorption and dehumidification device 14, thereby maintaining the adsorption effect of the moisture absorption and dehumidification device 14 on the water in the drying air. Since the heating device 15 is connected to the downstream side of the compressor 13 and the upstream side of the condenser 11, the high-temperature refrigerant flowing out of the compressor 13 flows into the heating device 15, so that the heating device 15 can exchange heat with the regeneration air, thereby heating the regeneration air. Without additional electric heating device for regenerating the moisture absorption and dehumidification device 14, the heat loss of the hot end of the compressor 13 can be reduced, and the energy consumption can be further reduced. Moreover, the electric heating device can avoid affecting the heat pump system.

[0058] In some embodiments, as shown in Figure 1 and Figure 2 The regeneration device further comprises a cooler 16, and the cooler 16 is used for dehumidifying the regeneration air. The cooler 16 is connected to at least the evaporator 10 through the refrigerant flow path. 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.

[0059] The regeneration device further comprises a cooler 16, and the cooler 16 is connected to at least the evaporator 10 through the refrigerant flow path. The cooler 16 can be located in the refrigerant flow path between the evaporator 10 and the compressor 13, or in the refrigerant flow path between the evaporator 10 and the heating device 15. The cooler 16 is provided with a refrigerant pipe through which the refrigerant passes and a regeneration air pipe through which the regeneration air passes. The refrigerant pipe and the regeneration air pipe are independent of each other, and heat exchange is performed between the two pipes in the cooler 16. The refrigerant is used to absorb heat from the regeneration air, so that the regeneration air is cooled and condensed, thereby reducing the humidity of the regeneration air.

[0060] The regeneration air circulation path is sequentially arranged with a dehumidification device 14, a cooler 16, and a heater 15. The regeneration air first passes through the dehumidification device 14, removing water from the device. It then passes through the cooler 16 to be dehumidified. Finally, it passes through the heater 15, where it is heated and transformed into dry, high-temperature regeneration air. The regeneration air is then passed into the dehumidification device 14, completing the regeneration air circulation process.

[0061] Thus, the cooler 16 can condense the water vapor in the regeneration air and continuously provide the dehumidification device 14 with low humidity regeneration air, so that the dehumidification device 14 can be stably regenerated, which helps maintain the dehumidification capacity and efficiency of the dehumidification device 14.

[0062] In some embodiments, as Figure 2 As shown, along the circulation path of the refrigerant, the compressor 13, the heating device 15, the condenser 11, the throttling component 12, the evaporator 10 and the cooler 16 are arranged in sequence.

[0063] The cooler 16 is provided in the refrigerant flow path between the evaporator 10 and the compressor 13. The refrigerant flow path sequentially flows through the compressor 13, the heating device 15, the condenser 11, the throttling component 12, the evaporator 10, the cooler 16, and returns from the cooler 16 to the compressor 13 to form a circulating refrigerant flow path.

[0064] The low-temperature and low-pressure gas-liquid two-phase refrigerant flowing out of the throttling component 12 first flows through the evaporator 10 to provide cooling capacity to the drying air, and then flows through the cooler 16 to provide cooling capacity to the regeneration air. The refrigerant itself absorbs heat step by step and vaporizes into low-temperature and low-pressure gas.

[0065] Since the refrigerant first passes through the evaporator 10 and then through the cooler 16, the condensation effect of the evaporator 10 can be improved, which is beneficial to improving 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 can be used as the auxiliary drying system.

[0066] In some embodiments, as Figure 1 As shown, along the circulation path of the refrigerant, the compressor 13, the heating device 15, the condenser 11, the throttling component 12, the cooler 16 and the evaporator 10 are arranged in sequence.

[0067] The cooler 16 is provided in the refrigerant flow path between the throttling component 12 and the evaporator 10. The refrigerant flow path sequentially flows through the compressor 13, the heating device 15, the condenser 11, the throttling component 12, the cooler 16, the evaporator 10, and returns from the evaporator 10 to the compressor 13 to form a circulating refrigerant flow path.

[0068] The low-temperature and low-pressure gas-liquid two-phase refrigerant flowing out of the throttling component 12 first flows through the cooler 16 to provide cold energy to the regeneration air, and then flows through the evaporator 10 to provide cold energy to the regeneration air, and the refrigerant itself is gradually heated and gasified into a low-temperature and low-pressure gas.

[0069] Since the refrigerant first passes through the cooler 16 and then passes through the evaporator 10, the condensation effect of the cooler 16 can be improved, which is beneficial to improve the drying capacity of the second drying system. The second drying system can be used as a main drying system, and the first drying system can be used as an auxiliary drying system.

[0070] In some embodiments, the first drying subsystem further comprises a first water pan, which is arranged below the evaporator 10 in the direction of gravity and is used to collect the condensed water condensed on the surface of the evaporator 10.

[0071] The first drying subsystem further comprises a first water pan. The first water pan is arranged below the evaporator 10 in the direction of gravity, and the condensed water condensed on the surface of the evaporator 10 falls into the first water pan, which collects and stores the condensed water.

[0072] Further, a drain pipe can be arranged to communicate with the first water pan. One end of the drain pipe communicates with the first water pan, and the other end of the drain pipe can communicate with a water storage box, which can store the condensed water. A drain pump can be arranged in the drain pipe or the water storage box to provide power for the discharge of the condensed water.

[0073] In this way, the first water pan collects the condensed water condensed on the evaporator 10, which is helpful for the subsequent centralized treatment of the condensed water.

[0074] In some embodiments, the second drying subsystem further comprises a second water pan, which is arranged below the cooler 16 in the direction of gravity and is used to collect the condensed water condensed on the surface of the cooler 16.

[0075] The second drying subsystem further comprises a second water pan. The second water pan is arranged below the cooler 16 in the direction of gravity, and the condensed water condensed on the surface of the cooler 16 falls into the second water pan, which collects and stores the condensed water.

[0076] Further, a drain pipe can be arranged to communicate with the second water pan. One end of the drain pipe communicates with the second water pan, and the other end of the drain pipe can communicate with a water storage box, which can store the condensed water. Two drain pipes can be arranged to respectively communicate with the first water pan and the second water pan, and the two drain pipes communicate with the same water storage box, so as to collect the condensed water on the evaporator 10 and the cooler 16 together. A drain pump can be arranged in at least one of the drain pipes or the water storage box to provide power for the discharge of the condensed water.

[0077] Thus, the second water pan collects the condensed water condensed on the condenser 16, and helps subsequent centralized treatment of the condensed water.

[0078] In some embodiments, the moisture absorption and removal device 14 comprises a rotating mechanism and a moisture absorption and removal assembly, the rotating mechanism is configured to drive the moisture absorption and removal assembly to rotate through a moisture absorption region and a regeneration region, the moisture absorption region is located in the circulation path of the drying air, and the regeneration region is located in the circulation path of the regeneration air.

[0079] The moisture absorption region is located in the circulation path of the drying air, and in the moisture absorption region, the moisture absorption and removal assembly can adsorb moisture in the drying air; the regeneration region is located in the circulation path of the regeneration air, and in the regeneration region, the moisture in the moisture absorption and removal assembly can be desorbed by the regeneration air.

[0080] Along the circulation path of the drying air, the moisture absorption region can be located between the evaporator 10 and the condenser 11. Along the circulation path of the regeneration air, the regeneration region is located on the downstream side of the heating device 15.

[0081] In some embodiments, the moisture absorption and removal assembly can be a dehumidification turntable, which can be a honeycomb or corrugated turntable carrying a moisture absorbent, capable of adsorbing and desorbing the absorbed water vapor to realize repeated desorption and regeneration. In some embodiments, the dehumidification turntable can include inorganic / organic fiber carriers (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), which are coated with a moisture absorbent such as molecular sieve, and the moisture absorbent is uniformly distributed between the fiber carriers and the surface of the fiber carriers to realize adsorption of the moisture in the air flow. The moisture absorbent can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to single-crystal molecular sieve or mixed-crystal molecular sieve such as A-type molecular sieve, X / Y-type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), high-molecular-weight moisture absorbent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with moisture absorption properties.

[0082] Regarding the rotating mechanism, for example, it can include a rotary motor and a rotating shaft, the rotating shaft is connected to the output end of the rotary motor, and the rotating shaft is connected to the moisture absorption and removal assembly (such as the center of the dehumidification turntable) and drives the moisture absorption and removal assembly to rotate around the rotating shaft.

[0083] Thus, by rotating the moisture absorption and removal assembly, repeated moisture absorption and regeneration of the moisture absorption and removal assembly can be realized; and by performing dehumidification and regeneration in the two regions respectively, the regeneration air and the drying air can be circulated independently, and the regeneration of the moisture absorption and removal assembly can be performed while drying the clothes, which is beneficial to improve the drying speed.

[0084] In some embodiments, the moisture absorption and removal assembly comprises a gas-permeable porous structure made of zeolite, lithium chloride, silica gel, modified silica gel or molecular sieve.

[0085] Thus, moisture adsorption and desorption can be easily and effectively achieved. The moisture absorption and removal assembly can be reused and has low cost.

[0086] In some embodiments, as shown in Figure 1 and Figure 2 , the drying system further comprises a drying cylinder 17 for carrying the objects to be dried, and the evaporator 10, the moisture absorption and removal device 14, the condenser 11 and the drying cylinder 17 are arranged in sequence along the circulation path of the drying air, wherein the evaporator 10 is used for dehumidifying the drying air, and the condenser 11 is used for heating the dehumidified drying air.

[0087] The drying air enters the drying cylinder 17 after passing through the condenser 11, passes through the objects to be dried in the drying cylinder 17, leaves the drying cylinder 17 to the evaporator 10, and then sequentially passes through the moisture absorption and removal device 14 and the condenser 11 from the evaporator 10, and finally returns to the drying cylinder 17 for continuous circulation.

[0088] Thus, a storage place is provided for the objects to be dried, and the drying air is used to dry the objects to be dried in the drying cylinder 17.

[0089] In some embodiments, continuing to refer to Figure 1 and Figure 2 , the drying system further comprises a filter screen 18, and the evaporator 10, the moisture absorption and removal device 14, the condenser 11, the drying cylinder 17 and the filter screen 18 are arranged in sequence along the circulation path of the drying air.

[0090] The filter screen 18 is arranged on the circulation path of the drying air between the drying cylinder 17 and the evaporator 10. The filter screen 18 can be arranged in the passage where the drying air leaves the drying cylinder 17, or can be arranged at the connection interface of the passage of the drying cylinder 17 and the drying air. Optionally, the filter screen 18 can be detachably installed.

[0091] Thus, the drying air leaving the drying cylinder 17 is filtered by the filter screen 18 before entering the circulation path starting from the evaporator 10, which helps to reduce the probability of blocking the circulation path by sundries.

[0092] In some embodiments, the drying system further comprises a first fan 19 located in the circulation path of the drying air, and the first fan 19 provides circulation power for the drying air; and the drying system further comprises a second fan 20 located in the circulation path of the regeneration air, and the second fan 20 provides circulation power for the regeneration air.

[0093] Thus, the drying air can be circulated under the driving of the first fan 19, and the regenerative air can be circulated under the driving of the second fan 20, so that the drying and desorption can be performed quickly and effectively.

[0094] The second aspect of the present application provides a clothes treatment apparatus including the drying system provided in the first aspect.

[0095] Since the clothes treatment apparatus includes the drying system capable of providing the drying air with low humidity, the to-be-dried object can be quickly and efficiently dried, the user waiting time is reduced, and the user experience is improved.

[0096] In some embodiments, the clothes treatment apparatus includes a clothes dryer, a washing and drying integrated machine.

[0097] Thus, the to-be-dried object can be quickly and efficiently dried after washing, the user can use the clothes immediately after washing, and the user experience is improved.
