[0033] Please refer to Figure 1 , the washing appliance 1000 of the embodiment of the present application includes an inner tank 1100 and a heat pump drying system 1200. The inner tank 1100 is provided with a washing chamber 1101. The heat pump drying system 1200 includes a duct component 100, a compressor 60 forming a closed refrigerant circuit, at least one condenser 30, a throttling device 90, and at least one evaporator 20. A ventilation opening 101 is formed at an end of the duct component 100, and the ventilation opening 101 is communicated with the washing chamber 1101. At least one evaporator 20 and at least one condenser 30 are both arranged in the duct component 100. At least one evaporator 20 is used to cool the gas flowing out of the inner tank 1100, and at least one condenser 30 is used to heat the gas flowing into the inner tank 1100. Among them, at least one heat exchanger in the evaporator 20 and the condenser 30 is used to exchange heat with the external environment.

[0034] In the washing appliance 1000 of the embodiment of the present application, the heat pump drying system 1200 exchanges heat with the external environment through the evaporator 20 and the condenser 30, which can reduce the evaporation temperature of the evaporator 20, thereby reducing the exhaust temperature of the compressor 60, and further improving the reliability of the compressor 60 and the drying efficiency of the washing appliance 1200.

[0035] Specifically, the washing appliance 1000 is mainly used for washing various tableware. Among them, the inner tank 1100 can be used as the main structure of the washing appliance 1000, and the washing chamber 1110 can be used as the place for actually cleaning items. A bracket for carrying and fixing tableware can be arranged in the washing chamber 1101, and a water cup 1300 is placed below the bracket. The water cup 1300 is used to collect and hold the water flow generated during the washing process. The washing appliance 1000 is, for example, a dishwasher.

[0036] The heat pump drying system 1200 is used to dry the humid-hot air flowing out of the inner container 1100 and heat the dried air so that the heated dried air flows back into the inner container 1100 again. In this way, the cycle is realized to achieve the effect of drying objects such as tableware. It should be noted that the dried air mentioned above is relative to the humid-hot air in the inner container 1100, and it does not mean that the air does not contain water vapor at all.

[0037] The evaporator 20 is a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 works, the evaporator 20 can refrigerate, thereby absorbing the heat of the air around the evaporator 20 to reduce the temperature of the surrounding air, so that the gas flowing through the evaporator 20 condenses to form condensed water, achieving the effect of drying the air.

[0038] The condenser 30 is also a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 works, the condenser 30 can heat, thereby releasing heat to the air around the condenser 30 to increase the temperature of the surrounding air, so that after the gas flowing through the condenser 30 enters the inner container 1100 of the washing appliance 1000 again, the effect of drying objects such as tableware is achieved.

[0039] The condenser 30 and the evaporator 20 are connected to the compressor 60 through the pipeline 61. The compressor 60, at least one condenser 30, the throttling device 90 and at least one evaporator 20 are connected to form a closed refrigerant circuit, so that the refrigerant as the refrigerant can circulate in the sealed refrigerant circuit formed by the compressor 60, the condenser 30, the throttling device 90 and the evaporator 20. The cooperation of the four can enable the heat pump drying system 1200 to achieve the effect of drying objects such as tableware. When the heat pump drying system 1200 is in the heating stage, the compressor 60 works, pumping the high-temperature and high-pressure refrigerant to the condenser 30 to heat the air. After the refrigerant exchanges heat with the air, it flows out of the condenser 30, and then passes through the throttling device 90 to be throttled into a low-temperature and low-pressure refrigerant and flows into the evaporator 20 to exchange heat and evaporate with the air, and then returns to the compressor 60 to complete the entire heat pump heating cycle. The dried air is heated by the condenser 30 and then enters the inner container 1100 of the washing appliance 1000 again. The throttling device 90 can be an expansion valve. Further, the throttling device 90 can be an electronic expansion valve.

[0040] Please refer to Figure 1, in some embodiments, the air duct component 100 is formed with a diversion channel 11. Both ends of the diversion channel 11 communicate with the washing chamber 1101. At least part of the evaporator 20 and at least part of the condenser 30 are provided in the same diversion channel 11. Along the diversion direction of the diversion channel 11, among all the evaporators 20 and condensers 30 located in the diversion channel 11, one evaporator 20 is located at the most upstream. The heat pump drying system 1200 is configured to first cool and dehumidify the air flowing out of the inner container 1100 by the evaporator 20 located in the diversion channel 11, and then heat it by the condenser 30 located in the diversion channel 11 and return it to the inner container 1100. Part of the evaporator 20 or part of the condenser 30 is arranged outside the diversion channel 11 and exchanges heat with the external environment.

[0041] In this way, among all the evaporators 20 and condensers 30 located in the diversion channel 11, one evaporator 20 is arranged at the most upstream in the diversion channel 11, so that the gas entering the diversion channel 11 is first pre-cooled by the evaporator 20, reducing the temperature of the air flow entering other evaporators 20, thereby reducing the ineffective cooling consumption of other evaporators 20 and improving the energy consumption utilization rate of the evaporator 20 for dehumidification in the heat pump drying system 1200.

[0042] Specifically, the diversion channel 11 formed by the air duct component 100 is used to achieve the ventilation effect, so that the gas can circulate between the inner container 1100 of the washing appliance 1000 and the heat pump drying system 1200. The evaporator 20 and the condenser 30 cooperate with each other to first cool and dry and then heat the air in the same diversion channel 11, so that the washing appliance 1000 can use the heat pump drying system to achieve the effect of drying items such as tableware.

[0043] The diversion channel 11 can be set in a curved shape or the like to meet the flow requirements of the air flow. The cross-sectional areas at different positions of the diversion channel 11 can be different. For example, the cross-sectional area of the position of the diversion channel 11 for accommodating the evaporator 20 and the condenser 30 is larger, and the cross-sectional areas of other positions are smaller.

[0044] The evaporator 20 is generally flat. The evaporator 20 can be placed vertically, or rather, the thickness direction of the evaporator 20 is arranged substantially horizontally, and the thickness direction of the evaporator 20 is substantially parallel to the central axis of the diversion channel 11, so as to increase the contact area between the gas in the diversion channel 11 and the evaporator 20, which is beneficial to improving the drying effect on the air flowing through the evaporator 20.

[0045] The condenser 30 is generally flat. The condenser 30 can be placed vertically, that is to say, the thickness direction of the condenser 30 is arranged substantially horizontally, and the thickness direction of the condenser 30 is substantially parallel to the central axis of the diversion channel 11, so as to increase the contact area between the gas in the diversion channel 11 and the condenser 30, which is beneficial to improving the heating effect on the air flowing through the condenser 30.

[0046] Part of the evaporator 20 and part of the condenser 30 can be a partial number of evaporators 20 and condensers 30, or can be a partial volume of the evaporators 20 and condensers 30. It can be that all the evaporators 20 and part of the condensers 30 are located in the diversion channel 11, and the other part of the condensers 30 are located outside the diversion channel 11, or all the condensers 30 and part of the evaporators 20 are located in the diversion channel 11, and the other part of the evaporators 20 are located outside the diversion channel 11, or part of the evaporators 20 and part of the condensers 30 are located in the diversion channel 11, and the other part of the evaporators 20 and the other part of the condensers 30 are located outside the diversion channel 11.

[0047] Please refer to Figure 1 and Figure 2 , in some embodiments, the number of condensers 30 is multiple, at least one condenser 30 is arranged in the diversion channel 11, and at least one condenser 30 is arranged outside the diversion channel 11 and exchanges heat with the external environment; or, the number of condensers 30 is one, a part of the condenser 30 is located in the diversion channel 11, and a part of the condenser 30 is located outside the diversion channel 11 and exchanges heat with the external environment.

[0048] In this way, by exchanging heat between the condenser 30 and the external environment, the condensation temperature of the condenser 30 can be reduced, thereby reducing the evaporation temperature of the evaporator 20 and the exhaust temperature of the compressor 60, and further improving the reliability of the compressor 60 and the drying efficiency of the washing appliance 1200 when operating in the drying mode.

[0049] For example, the number of condensers 30 is two, one of the condensers 30 is located in the diversion channel 11, and the other condenser 30 is located outside the diversion channel 11 and is between the compressor 60 and the condenser 30 in the diversion channel 11; or, one of the condensers 30 is located in the diversion channel 11, and a part of the other condenser 30 is located in the diversion channel 11, and the other part is located outside the diversion channel 11.

[0050] Another example, the number of condensers 30 is three, two of the condensers 30 are located in the diversion channel 11, and the other condenser 30 is located outside the diversion channel 11, or one of the condensers 30 is located in the diversion channel 11, and the other two condensers 30 are located outside the diversion channel 11, or at least a part of one condenser 30 is located in the diversion channel 11, and the other part is located outside the diversion channel 11.

[0051] Multiple evaporators 20 with the same power can be used, or evaporators 20 of different models, sizes, and types can be used to match the size and installation space of the air duct component 100 and achieve appropriate cooling and dehumidifying effects at different positions in the diversion channel 11. Similarly, multiple condensers can all have the same power or different powers.

[0052] Please refer to Figure 3 and Figure 4 , in some embodiments, the number of evaporators 20 is multiple, at least one evaporator 20 is disposed in the diversion channel 11, and at least one evaporator 20 is disposed outside the diversion channel 11 and exchanges heat with the external environment; or, the number of evaporators 20 is one, a part of the evaporator 20 is located in the diversion channel 11, and a part of the evaporator 20 is located outside the diversion channel 11 and exchanges heat with the external environment.

[0053] Thus, by exchanging heat between the evaporator 20 and the external environment, the evaporation temperature of the evaporator 20 and the suction gas temperature of the compressor 60 can be reduced, thereby reducing the discharge temperature of the compressor 60, and further improving the reliability of the compressor 60 and the drying efficiency of the washing appliance 1200 when operating in the drying mode.

[0054] For example, the number of evaporators 20 is two, one of the evaporators 20 is located in the diversion channel 11, and the other evaporator 20 is located outside the diversion channel 11 and is between the compressor 60 and the evaporator 20 in the diversion channel 11; or, one of the evaporators 20 is located in the diversion channel 11, and a part of the other evaporator 20 is located in the diversion channel 11, and the other part is located outside the diversion channel 11.

[0055] For another example, the number of evaporators 20 is three, two of the evaporators 20 are located in the diversion channel 11, and the other evaporator 20 is located outside the diversion channel 11, or, one of the evaporators 20 is located in the diversion channel 11, and the other two evaporators 20 are located outside the diversion channel 11, or, at least a part of one evaporator 20 is located in the diversion channel 11, and the other part is located outside the diversion channel 11.

[0056] Multiple evaporators 20 with the same power can be used, or evaporators 20 of different models, sizes, and types can be used to match the size and installation space of the air duct component 100 and achieve appropriate cooling and dehumidifying effects at different positions in the diversion channel 11. Similarly, multiple condensers 30 can all have the same power or different powers.

[0057] In one embodiment, the number of the condenser 30 and the evaporator 20 is one each. It may be that the condenser 30 is located in the diversion channel 11, and a part of the evaporator 20 is located in the diversion channel 11 while the other part is outside the diversion channel 11; or the evaporator 20 is located in the diversion channel 11, and a part of the condenser 30 is located in the diversion channel 11 while the other part is outside the diversion channel 11; or a part of the condenser 30 and a part of the evaporator 20 are both located in the diversion channel 11, and the other part of the condenser 30 and the other part of the evaporator 20 are both outside the diversion channel 11.

[0058] Please refer to Figure 5 , in some embodiments, when at least one condenser 30 exchanges heat with the external environment, the heat pump drying system 1200 is configured to introduce the external gas heated by at least one condenser 30 into the inner container 1100.

[0059] In this way, introducing the external gas heated by at least one condenser 30 into the inner container 1100 can achieve the effect of drying items such as tableware.

[0060] Specifically, an air guide opening 1102 can be provided on the side wall of the inner container 1100, and the external gas enters the inner container 1100 through the air guide opening 1102 after being heated by at least one condenser 30.

[0061] Please refer to Figure 1 and Figure 6 , in certain embodiments, the evaporator 20 and / or the condenser 30 each include a plurality of fins 21, and an air flow channel 22 is formed between the plurality of fins 21. The diversion direction of the air flow channel 22 is the same as that of the diversion channel 11.

[0062] In this way, the fins 21 can increase the contact area between the evaporator 20 and / or the condenser 30 and the air, enabling the refrigerant to quickly absorb the heat in the air and continuously introduce the hot air in the environment into the air flow channel 22, thereby improving the heat exchange efficiency.

[0063] Specifically, a plurality of fins 21 can be provided on the evaporator 20, or a plurality of fins 21 can be provided on the condenser 30, or a plurality of fins 21 can be provided on both the evaporator 20 and the condenser 30. The plurality of fins 21 are arranged at intervals in a direction perpendicular to the diversion direction of the diversion channel 11. After being controlled by the throttling device 90, the temperature of the refrigerant drops below the ambient temperature. Therefore, when the humidity of the air flow entering the evaporator 20 is relatively high, the water vapor in the air flow easily condenses on the evaporator 20 to form condensed water, which flows down through the air flow channel 22.

[0064] The shape of the fin 21 can be square sheet-shaped, and the material of the fin 21 can be a metal material with high thermal conductivity, such as copper. It can be understood that the shape of the fin 21 can also be other shapes, and specific shapes are not limited.

[0065] In some embodiments, the thickness direction of the fin 21 is the same as the horizontal direction, and the height of the fin 21 is greater than the width of the fin 21.

[0066] In this way, the width of the fin 21 is small, which can reduce the area occupied by the evaporator 20 and / or the condenser 30 in the diversion channel 11, and further reduce the area occupied by the air duct component 100 on the heat pump drying system 1200, so that the structure of the washing appliance 1000 is compact.

[0067] Specifically, the width direction of the fin 21 is the diversion direction of the diversion channel 11, the thickness direction of the fin 21 is the horizontal direction perpendicular to the width direction of the fin 21, and the height direction of the fin 21 is the vertical direction perpendicular to the thickness and width directions of the fin 21. The width direction of the fin 21 can be parallel to the width direction of the evaporator 20 and / or the condenser 30.

[0068] Please refer to Figure 1 、 Figure 7 and Figure 8 As shown in, in some embodiments, the air duct component 100 includes an air duct housing 10, an intake pipe 70, and an exhaust pipe 80. The intake pipe 70 and the exhaust pipe 80 are both communicated with the air duct housing 10. The evaporator 20 and the condenser 30 are arranged at intervals in the air duct housing 10. The air duct housing 10, the intake pipe 70, and the exhaust pipe 80 together form a diversion channel 11.

[0069] In this way, the intake pipe 70 can direct the gas in the inner tank 1100 into the air duct housing 10, and the exhaust pipe 80 can introduce the gas that has passed through the evaporator 20 and the condenser 30 in sequence into the inner tank 1100, realizing the circulating flow of the gas between the air duct component 100 and the inner tank 1100. In addition, arranging the evaporator 20 and the condenser 30 in the air duct housing 10 enables the air duct housing 10, the evaporator 20, and the condenser 30 to form an integral module, which is convenient for assembling the washing appliance 1000 and is beneficial to reducing the manufacturing cost of the washing appliance 1000.

[0070] Specifically, the air duct housing 10 is used for ventilation. The entire air duct housing 10 can be made of materials that are easy to mold, such as plastics, so that the air duct housing 10 is easy to manufacture. The air duct housing 10 can be set to a specific external structure according to the installation position of the air duct component 100, so that the air duct component 100 fits more tightly with the surrounding components. The air duct housing 10 is communicated with the inner tank 1100.

[0071] The intake pipe 70 and the air duct housing 10 can be integrally formed structures or separable and detachable structures. Similarly, the exhaust pipe 80 and the air duct housing 10 can be integrally formed structures or separable and detachable structures.

[0072] Since the humid and hot air in the inner tank 1100 flows upward, and objects such as tableware are located below the top of the inner tank 1100, in order to achieve a better drying effect, in some embodiments, the end of the intake pipe 70 connected to the inner tank 1100 is higher than the end of the exhaust pipe 80 connected to the inner tank 1100. This allows the intake pipe 70 to more easily extract the humid and hot air in the inner tank 1100, and the exhaust pipe 80 can discharge the dry hot air to a position below the top of the inner tank 110, thereby better drying objects such as tableware.

[0073] In some embodiments, the intake pipe 70 and the exhaust pipe 80 can both be connected to the side wall of the inner tank 1100. For example, the intake pipe 70 and the exhaust pipe 80 can both be connected to the left side wall, the right side wall, or the rear side wall of the inner tank 1100, thereby reducing interference between the intake pipe 70 and the exhaust pipe 80 and other components of the washing appliance 1000 and improving the reliability of the washing appliance 1000.

[0074] In some embodiments, the intake pipe 70 can be connected to the top wall of the inner tank 1100, while the exhaust pipe 80 is connected to the side wall of the inner tank 1100.

[0075] Please refer to Figure 1 , in some embodiments, the vent 101 includes an air inlet 71 and an air outlet 81. The connection between the intake pipe 70 and the inner tank 1100 forms the air inlet 71, and the connection between the exhaust pipe 80 and the inner tank 1100 forms the air outlet 81. One end of the diversion channel 11 communicates with the washing chamber 1101 through the air inlet 71, and the other end of the diversion channel 11 communicates with the washing chamber 1101 through the air outlet 81. In this way, the humid and hot air in the washing chamber 1101 can flow into the diversion channel 11 through the air inlet 71, be dried and heated in the diversion channel 11, and then flow into the washing chamber 1101 through the air outlet 81 to dry the tableware. This cycle is repeated to achieve the effect of drying the tableware.

[0076] Specifically, the exhaust pipe 80 can form a plurality of air outlets 81, and the plurality of air outlets 81 are arranged at intervals along the height direction of the inner tank 1100. This allows the air outlets 81 to discharge the dried hot air to different positions in the washing chamber 1101, thereby achieving a better drying effect.

[0077] The number of air outlets 81 can be two, three, four, etc. The present application does not limit the specific number of air outlets 81.

[0078] Please refer to Figure 7, in some embodiments, the air duct housing 10 includes a main body portion 12 and two interface portions 13. Both of the two interface portions 13 are connected to the main body portion 12 and are spaced apart from each other on the same side of the main body portion 12. One of the interface portions 13 is for air intake, and the other interface portion 13 is for air outlet. The evaporator 20 and the condenser 30 are both disposed within the main body portion 12.

[0079] In this way, the air duct housing 10 forms the main body portion 12 and the interface portions 13 according to different functions, enabling the air duct housing 10 to meet the requirements for installing the evaporator 20 and the condenser 30 and to achieve the function of ventilation. In addition, both of the two interface portions 13 are connected to the same side of the main body portion 12, such that both the air intake and the air outlet of the air duct housing 10 are located on the same side, which is conducive to the assembly of the air duct housing 10 with other components and reduces the interference between the air duct housing 10 and the surrounding components, and the structure is simple.

[0080] Specifically, the volume of the main body portion 12 is larger than that of the interface portions 13, enabling the main body to accommodate the evaporator 20 and the condenser 30 and also making it easier for the interface portions 13 to be connected to other pipe fittings. The main body portion 12 is generally in a square block shape as a whole. The evaporator 20 and the condenser 30 can be fixed inside the main body portion 12 by means of snap connection, threaded connection, etc.

[0081] The interface portions 13 protrude from the surface of the main body portion 12. The interface portions 13 are similar to flat tubes. The interface portions 13 can be located on one side in the length direction or the width direction of the main body portion 12. The features such as the shape, structure, and size of the two interface portions 13 can be the same, thereby reducing the manufacturing cost of the air duct housing 10.

[0082] It can be understood that both the main body portion 12 and the two interface portions 13 form a part of the flow guiding channel 11. When the air duct housing 10 is ventilated, the gas sequentially passes through one of the interface portions 13, the main body portion 12, and the other interface portion 13.

[0083] Please refer to Figure 7 and Figure 9 , in some embodiments, the heat pump drying system further includes a tray 50. Both the compressor 60 and the air duct housing 10 are mounted on the tray 50. The compressor 60 and the air duct housing 10 form an integral body through the tray 50, which is conducive to the installation of the heat exchange module 100 as an integral body and improves the assembly efficiency of the washing appliance 1000.

[0084] Please refer to Figure 1 and Figure 8, in some embodiments, the heat pump drying system 1200 includes a fan 40. The fan 40 is configured to form an air flow in the air duct housing 10. The air flow flows out from the inner tank 1100 and passes through the evaporator 20 and the condenser 30 in sequence before entering the inner tank 1100 again. Thus, the fan 40 can provide power for the gas flow in the diversion channel 11.

[0085] Specifically, the fan 40 can be an axial flow fan 40 or a centrifugal fan 40. When the fan 40 operates, a negative pressure is formed in the diversion channel 11, causing the gas to circulate along the path of inner tank 1100 → intake pipe 70 → air duct housing 10 → exhaust pipe 80 → inner tank 1100.

[0086] Please refer to Figure 8 , in certain embodiments, the number of fans 40 is at least two. At least one fan 40 is installed on the air duct housing 10, and at least one fan 40 is disposed on the intake pipe 70. For example, the fan 40 can be installed on the air duct housing 10 or the intake pipe 70 by means of screws. Thus, at least two fans 40 can increase the flow rate of the gas in the diversion channel 11, thereby enhancing the drying effect of the heat pump drying system 1200.

[0087] Specifically, the number of fans 40 can be two, three, four, etc. At least one fan 40 is installed on the main body portion 12 of the air duct housing 10, so that the air duct housing 10 can provide a larger space for the installation of the fan 40. It can be that at least a part of one fan 40 is located in the diversion channel 11 and downstream of the condenser 30. After the fan 40 is started, a negative pressure can be formed on the side facing the condenser 30, thereby sucking the air around the condenser 30 to make the gas flow. It can also be that at least a part of one fan 40 is located in the diversion channel 11 and downstream of the condenser 30, and at least a part of the other fan 40 is located in the diversion channel 11 and upstream of the evaporator 20.

[0088] Since the diversion channel 11 between the main body portion 12 and the interface portion 13 is non-linear, in order to reduce the resistance of gas flow, the fan 40 adopts a centrifugal fan 40, and the air outlet of the fan 40 faces the interface portion 13, so that the gas can be directly discharged to the interface portion 13.

[0089] At least one blower 40 is disposed on the intake pipe 70, that is, the end of the intake pipe 70 forming the air inlet 71 or the pipe section near the air inlet 71, so that a larger space can be provided for the installation of the blower 40 at the intake end of the intake pipe 70. At least a part of one blower 40 may be located in the intake pipe 70 and upstream of the evaporator 20. After the blower 40 is started, a positive pressure can be formed on the side facing the evaporator 20, thereby driving the air around the evaporator 20 to enable gas flow. It is also possible that at least a part of one blower 40 is located at the intake end of the intake pipe 70 and at least a part of the other blower 40 is located at the outlet end of the intake pipe 70.

[0090] In some embodiments, the blower 40 is only installed on the air duct housing 10. That is, at least one blower 40 is provided in the air duct housing 10 of the heat pump drying system 1200 to provide power for the gas flow in the diversion channel 11.

[0091] Please refer to Figure 1 , in some embodiments, the washing appliance 1000 includes a baffle 1400, the baffle 1400 is movably disposed at the vent 101, and the baffle 1400 is used to isolate or communicate the washing chamber 1101 with the air duct component 100. Thus, by isolating the washing chamber 1101 from the air duct component 100 during the washing process by the baffle 1400 and communicating the washing chamber 1101 with the air duct component 100 during the drying process, the oil stains, detergents, etc. in the washing chamber 1101 entering the air duct component 100 are reduced, and appliances such as the evaporator 20 and the condenser 30 in the air duct component 100 are prevented from being contaminated, improving the reliability of the heat pump drying system 1200.

[0092] Specifically, after the washing is completed, the baffle 1400 moves relative to the air duct component 100 and opens the vent 101, and the washing chamber 1101 is internally communicated with the air duct component 100, and the heat pump drying system 1200 operates to dehumidify and heat the air in the washing chamber 1101 and the air duct component 100. After the tableware is dried, or before the next washing program starts, the baffle 1400 can move relative to the air duct component 100 again and cover the vent 101 to isolate the washing chamber 1101 from the air duct component 100.

[0093] A baffle 1400 can be provided at each of the air inlet 71 and the air outlet 81. The baffle 1400 can also be provided only at the air inlet 71 or the air outlet 81. The baffle 1400 can be in the structure of a thin plate or a thin sheet. The area of the baffle 1400 is greater than or equal to the cross-sectional area of the ventilation opening 101 to ensure that the baffle 1400 can fully cover the ventilation opening 101. The cross-section of the ventilation opening 101 refers to the section formed along the direction perpendicular to the air flow direction through the ventilation opening 101. The present application does not limit the shape of the baffle 1400. The shape of the baffle 1400 can match the cross-sectional shape of the ventilation opening 101. For example, the cross-sections of the baffle 1400 and the ventilation opening 101 are both oval, and the baffle 1400 and the cross-section of the ventilation opening 101 are concentric. The major axis of the baffle 1400 is greater than the minor axis of the cross-section of the ventilation opening 101, and the minor axis of the baffle 1400 is greater than the minor axis of the cross-section of the ventilation opening 101. Another example is that the shape of the baffle 1400 is different from that of the ventilation opening 101, and the dimensions of the baffle 1400 in all directions are greater than the dimensions of the cross-section of the ventilation opening 101 in the same direction.

[0094] Further, by closely matching the baffle 1400 with the channel wall surface at the ventilation opening 101, the sealing effect inside the washing chamber 1101 and the air duct component 100 during the washing process can be improved, and the risk of the heat pump drying system being contaminated can be reduced.

[0095] The present application does not limit the movement mode of the baffle 1400 relative to the air duct component 100. The baffle 1400 can be movably arranged relative to the air duct component 100 in various ways such as rotation, swinging, translation, sliding, and twisting.

[0096] Please refer to Figure 1 , in some embodiments, the washing appliance 1000 further includes a driving device 1410 connected to the baffle 1400, and the driving device is used to drive the baffle to rotate. In this way, by connecting the driving device 1410 to the baffle 1400, a driving force is provided for the baffle 1400, further ensuring the reliability of the movable structure of the baffle 1400.

[0097] Specifically, the driving device 1410 is a structure capable of providing a driving force to drive the baffle 1400 to rotate. The driving modes of the driving device 1410 include but are not limited to motor driving, hydraulic driving, air pump driving, thermal driving, etc. The driving device 1410 can include one or more transmission structures such as a rotating shaft, a rotating rod, a gear, a chain, a cam, and a bearing. The transmission structure is connected to the baffle 1400 to drive the baffle 1400 to rotate. For example, the driving device 1410 includes a rotating shaft connected to one side edge of the baffle 1400. The rotating shaft is arranged at the air outlet. The rotating shaft is connected to the baffle 1400 and serves as the rotation center of the baffle 1400. The rotating shaft is configured to rotate along the direction of the air flow in and out at the air outlet.

[0098] In some embodiments, the driving device 1410 controls the rotation angle of the baffle 1400 by providing a braking force to the baffle 1400.

[0099] In other embodiments, a limiting device, such as a bump, a clamping groove, etc., may be provided in the air duct component 100 to limit the rotation angle of the baffle 1400.

[0100] Before the start of washing, the baffle 1400 rotates relative to the air duct component 100 by a certain angle until the ventilation opening 101 is completely blocked, separating the washing chamber 1101 from the air duct component 100. After the washing is completed and before the compressor 60, the evaporator 20, and the condenser 30 in the heat pump drying system 1200 are started, the baffle 1400 rotates from the state of blocking the ventilation opening 101 to another angle to open the ventilation opening 101, connecting the washing chamber 1101 and the air duct component 100.

[0101] In some embodiments, the rotation center of the baffle 1400 is located at one side edge of the ventilation opening 101, and the baffle 1400 rotates along the direction of the air flowing through the ventilation opening 101, forming a structure similar to a door panel. When the baffle 1400 rotates relative to the air duct component 100 until the ventilation opening 101 is fully open, the baffle 1400 may be located in the diversion channel 11 and form an angle slightly less than 90° with the plane where the ventilation opening 101 is located.

[0102] In other embodiments, the baffle 1400 rotates along the direction parallel to the cross-section of the ventilation opening 101 to block and open the ventilation opening 101.
