[0040] Please refer to Figure 1 , the washing appliance 1000 of the embodiments of the present application includes an inner tank 1100 and a heat pump drying system 1200. The heat pump drying system 1200 is connected to the inner tank 1100. The heat pump drying system 1200 is used to dry the humid and hot air flowing out of the inner tank 1100 and heat the dried air, so that the heated and dried air flows back into the inner tank 1100 again. In this way, the cycle is realized to achieve the effect of drying objects such as tableware. The washing appliance 1000 is, for example, a dishwasher.

[0041] It should be noted that the dried air mentioned above is relative to the humid and hot air in the inner tank 1100, and does not mean that the air contains no water vapor at all.

[0042] Please refer to Figures 1-4 In some embodiments, the inner container 1100 is provided with a first through hole 1102 and a second through hole 1103, and the first through hole 1102 and the second through hole 1103 are spaced apart. The heat pump drying system 1200 includes a duct component 100, a compressor 60, a condenser 30, a throttling device 90, and an evaporator 20 that are connected in sequence to form a closed refrigerant circuit. The duct component 100 forms a diversion channel 11. The duct component 100 includes an intake pipe 70 and an exhaust pipe 80. The intake pipe 70 and the exhaust pipe 80 are disposed on the same side wall 1101 of the inner container 1100. The intake end of the intake pipe 70 is docked with the first through hole 1102, and the exhaust end of the exhaust pipe 80 is docked with the second through hole 1103. The evaporator 20 is configured to cool the gas flowing out of the inner container 1100 and passing through the intake pipe 70, and the condenser 30 is configured to heat the gas flowing toward the exhaust pipe 80.

[0043] Thus, in the washing appliance 1000 according to the embodiment of the present application, the intake pipe 70 and the exhaust pipe 80 are disposed on the same side wall 1101, and the intake end of the intake pipe 70 is docked with the first through hole 1102, and the exhaust pipe 80 is formed with an exhaust end docked with the second through hole 1103, so that the intake pipe 70 and the exhaust pipe 80 can be more conveniently combined with the inner container 1100, making the structure of the duct component 100 simpler, which is beneficial to improving the reliability of the washing appliance 1000 and reducing the manufacturing cost.

[0044] Specifically, as Figures 2-4 shown, the inner container 1100 forms a washing chamber 1104 having an opening, and objects such as tableware can be placed into the washing chamber 1104 through the opening of the washing chamber 1104. A bracket for carrying and fixing tableware may be provided in the washing chamber 1104. A water cup 1300 is provided below the washing chamber 1104. The water cup 1300 is configured to collect and drain the water flow generated during washing and condensation.

[0045] The first through hole 1102 and the second through hole 1103 are holes penetrating the side wall 1101 of the inner container 1100. The first through hole 1102 and the second through hole 1103 may be disposed on the same side wall 1101 of the inner container 1100, or may be disposed on different side walls 1101 of the inner container 1100. Exemplarily, the first through hole 1102 and the second through hole 1103 may be simultaneously disposed on the left side wall 1101, the right side wall 1101, the rear side wall 1101, or the top wall of the inner container 1100, or may be respectively disposed on the left side wall 1101, the right side wall 1101, the rear side wall 1101, or the top wall of the inner container 1100. For example, the first through hole 1102 is disposed on the top wall of the inner container 1100, and the second through hole 1103 is disposed on the left side wall 1101 of the inner container 1100.

[0046] The evaporator 20 is a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 is operating, the evaporator 20 can refrigerate, thereby absorbing the heat of the air around the evaporator 20 to lower 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.

[0047] 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.

[0048] The condenser 30 is also a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 is operating, the condenser 30 can heat, thereby absorbing the heat for heating the surrounding air to increase the temperature of the surrounding air, so that after the gas flowing through the condenser 30 enters the inner tank 1100 of the dishwashing appliance 1000 again, the effect of drying objects such as tableware is achieved.

[0049] The condenser 30 is generally flat. The condenser 30 can be placed vertically, or rather, 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 make the contact area between the gas in the diversion channel 11 and the condenser 30 larger, which is beneficial to improving the heating effect on the air flowing through the condenser 30.

[0050] In the embodiment of the present application, the heat pump drying system 1200 is modularly designed. When the dishwashing appliance 1000 is assembled, the number of components to be assembled in the dishwashing appliance 1000 can be reduced, the assembly effect of the dishwashing appliance 1000 can be improved, and thus the manufacturing cost of the dishwashing appliance 1000 can be reduced.

[0051] The compressor 60, the condenser 30, the throttling device 90, and the evaporator 20 are the main components of the heat pump drying system 1200 of the washing appliance 1000. They are connected in sequence to form a closed refrigerant circuit, enabling the refrigerant to circulate in the sealed refrigerant circuit composed of 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 drying stage, the compressor 60 operates to pump 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, then passes through the throttling device 90 for throttling and becomes a low-temperature and low-pressure refrigerant, which 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.

[0052] The air duct component 100 enables the air in the washing chamber 1104 to form a circulating air flow. For example, the gas in the inner container 1100 enters the air duct component 100 from the intake end of the intake pipe 70, and after passing through the air duct component 100, it is discharged from the exhaust end of the exhaust pipe 80 to the inner container 1100.

[0053] The diversion channel 11 formed by the air duct component 100 is used to achieve the effect of ventilation, enabling the gas to circulate between the inner container 1100 of the washing appliance 1000 and the diversion channel 11 to achieve the effect of drying objects such as tableware. The diversion channel 11 can be set in a curved shape or other shapes 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.

[0054] The intake pipe 70 and the exhaust pipe 80 are at least partially attached to the same side wall 1101 of the inner tank 1100. The intake pipe 70 and the exhaust pipe 80 can both be flat pipes, so as to facilitate the fitting and installation with the side wall 1101 of the inner tank 1100. The docking of the intake end of the intake pipe 70 with the first through hole 1102 means that the intake end of the intake pipe 70 can be inserted into the first through hole 1102, or can cover the first through hole 1102 on the outer surface of the side wall 1101 of the inner tank 1100. Similarly, the docking of the exhaust end of the exhaust pipe 80 with the second through hole 1103 means that the exhaust end of the exhaust pipe 80 can be inserted into the second through hole 1103, or can cover the second through hole 1103 on the outer surface of the side wall 1101 of the inner tank 1100. In one embodiment, the first through hole 1102 is provided on the top wall of the inner tank 1100, and the second through hole 1103 is provided on the right side wall 1101 of the inner tank 1100, that is, the intake pipe 70 is partially attached to the right side wall 1101 of the inner tank 1100, and the exhaust pipe 80 is entirely attached to the right side wall 1101 of the inner tank 1100. In another embodiment, the first through hole 1102 and the second through hole 1103 are both provided on the right side wall 1101 of the inner tank 1100, that is, the intake pipe 70 and the exhaust pipe 80 are entirely attached to the right side wall 1101 of the inner tank 1100.

[0055] Please refer to Figure 3 and Figure 4 , in some embodiments, the height of the first through hole 1102 is higher than the height of the second through hole 1103. 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 height of the first through hole 1102 is higher than the height of the second through hole 1103, so that the height of the exhaust end of the exhaust pipe 80 is lower than the height of the intake end of the intake pipe 70, enabling 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 1100, thereby better drying objects such as tableware.

[0056] Please refer to Figures 2-4 , in some embodiments, the intake pipe 70 and the exhaust pipe 80 are arranged side by side along the depth direction of the inner tank 1100. Since there is more installation space in the depth direction of the inner tank 1100, arranging the intake pipe 70 and the exhaust pipe 80 side by side along the depth direction of the inner tank 1100 can reasonably utilize the space of the washing appliance 1000 and reduce the interference between the intake pipe 70, the exhaust pipe 80 and other components. The depth direction of the inner tank 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0057] Please refer to Figures 1-5, in some embodiments, the evaporator 20 and / or the condenser 30 each includes a plurality of fins 21, an air flow channel 22 is formed between the plurality of fins 21, and the guiding direction of the air flow channel 22 is the same as the guiding direction of the guiding channel 11.

[0058] In this way, the fins 21 can increase the contact area between the evaporator 20 and / or the condenser 30 and the air, so that the refrigerant can quickly absorb and release heat, improving the heat exchange efficiency.

[0059] Specifically, a plurality of fins 21 may be provided on the evaporator 20, or a plurality of fins 21 may be provided on the condenser 30, or a plurality of fins 21 may be provided on both the evaporator 20 and the condenser 30. The plurality of fins are arranged at intervals in a direction perpendicular to the guiding direction of the guiding channel 11. After being controlled by the throttling device 143, the temperature of the refrigerant is reduced to be lower than 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 is likely to condense on the evaporator 144 to form condensed water, which flows down through the air flow channel 22.

[0060] The shape of the fin 21 may be a square sheet, and the material of the fin 21 may be a metal material with relatively high thermal conductivity, such as copper. It can be understood that the shape of the fin 21 may also be other shapes, which are not specifically limited.

[0061] 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.

[0062] In this way, the width of the fin 21 is relatively small, which can reduce the area occupied by the evaporator 20 and / or the condenser 30 in the guiding 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.

[0063] Specifically, the width direction of the fin 21 is the guiding direction of the guiding 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.

[0064] Please refer to Figures 1-4, in some embodiments, the air duct component 100 includes an air duct housing 10, an evaporator 20 and a condenser 30 are spaced apart in the air duct housing 10. Along the flow direction of the diversion channel 11, the evaporator 20 is located upstream of the condenser 30. 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, and then heat it by the condenser 30 and return it to the inner container 1100. Thus, the evaporator 20 and the condenser 30 cooperate with each other to also cool, dry and then heat the air in the diversion channel 11, so that the washing appliance 1000 can utilize the heat pump system 1200 to achieve the effect of drying items such as tableware. In some embodiments, the condenser 30 and the evaporator 20 are connected to the compressor 60 through a pipeline 61.

[0065] Specifically, the air duct housing 10 is installed on the base 1400 of the washing appliance 1000 and is located below the inner container 1100. The base 1400 of the washing appliance 1000 can provide support for the air duct housing 10 and the inner container 1100, so that the installation of the air duct component 100 and the inner container 1100 is stable. The air duct housing 10 can be directly installed on the base 1400 or can be installed on the base 1400 through other media.

[0066] The intake pipe 70 and the air duct housing 10 can be an integrally formed structure or a separable and detachable structure. Similarly, the exhaust pipe 80 and the air duct housing 10 can be an integrally formed structure or a separable and detachable structure.

[0067] The air duct housing 10 is used for ventilation. The air duct housing 10 as a whole can be made of materials such as plastics that are easy to mold, 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 heat exchange pump drying system 1200, so that the heat pump drying system 1200 cooperates with the surrounding components more compactly. The air duct housing 10 is communicated with the inner container 1100. The air duct housing 10 being located below the inner container 1100 can mean that the top of the air duct housing 10 is lower than the bottom of the inner container 1100.

[0068] The evaporator 20 and the condenser 30 are spaced apart in the air duct housing 10. It can be that the condenser 30 and the evaporator 20 are located in the same diversion channel 11 and are separated by a certain distance, or it can be that the condenser 30 and the evaporator 20 are respectively located in different diversion channels 11. The evaporator 20 being located upstream of the condenser 30 means that the gas from the inner container 1100 first passes through the evaporator 20 for cooling and dehumidification and then passes through the condenser 30 for heating.

[0069] Please refer to Figures 1-4 and Figure 7, in some embodiments, the evaporator 20, the condenser 30, the intake pipe 70, and the exhaust pipe 80 are all located on the same side of the inner container 1100. This enables the evaporator 20, the condenser 30, the intake pipe 70, and the exhaust pipe 80 to be more conveniently combined with the inner container 1100, simplifies the structure of the air duct component 100, further improves the reliability of the washing appliance 1000, and reduces the manufacturing cost.

[0070] Specifically, the evaporator 20, the condenser 30, the intake pipe 70, and the exhaust pipe 80 may all be located on the same side wall 1101 of the inner container 1100. For example, the evaporator 20, the condenser 30, the intake pipe 70, and the exhaust pipe 80 are all located on the left side wall 1101, the right side wall 1101, or the rear side wall 1101 of the inner container 1100.

[0071] Please refer to Figures 1-4 and Figure 7 , in some embodiments, the condenser 30 and the evaporator 20 are located on the same side of the bottom wall of the inner container 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall of the inner container 1100 on the same side as the intake pipe 70 and the exhaust pipe 80. This can reduce the interference of the evaporator 20 and the condenser 30 on the combination of the intake pipe 70 and the exhaust pipe 80 with the inner container 1100, simplifies the structure of the air duct component 100, further improves the reliability of the washing appliance 1000, and reduces the manufacturing cost.

[0072] Specifically, the intake pipe 70 and the exhaust pipe 80 may be located on the right side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 may be located below the bottom wall on the right side of the inner container 1100.

[0073] In one embodiment, the evaporator 20, the intake pipe 70, the condenser 30, and the exhaust pipe 80 may be located on different sides of the inner container 1100. For example, the evaporator 20 and the intake pipe 70 are located on the left side of the inner container 1100, and the condenser 30 and the exhaust pipe 80 are located on the right side of the inner container 1100. Exemplarily, the evaporator 20 and the intake pipe 70 may be located on the left side wall 1101 of the inner container 1100, and the condenser 30 and the exhaust pipe 80 may be located on the right side wall 1101 of the inner container 1100. Or, the intake pipe 70 is located on the left side wall 1101 of the inner container 1100, the evaporator 20 is located below the bottom wall on the left side of the inner container 1100, the exhaust pipe 80 is located on the right side wall 1101 of the inner container 1100, and the condenser 30 is located below the bottom wall on the right side of the inner container 1100.

[0074] It should be noted that the left and right sides of the inner container 1100 described in this application refer to taking the opening of the inner container 1100 as the front, and the plane with the same distance from the left and right side walls 1101 as the reference plane. The left side of the reference plane is the left side of the inner container 1100, and the right side of the reference plane is the right side of the inner container 1100.

[0075] Please refer to Figure 6 、 Figure 8 and Figure 9 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 connected to the intake pipe 70, and the other interface portion 13 is connected to the exhaust pipe 80. The evaporator 20 and the condenser 30 are arranged adjacent to each other within the main body portion 12.

[0076] 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 ventilation function. Additionally, both of the two interface portions 13 are connected to the same side of the main body portion 12, such that the intake and exhaust of the air duct housing 10 are both on the same side. This is beneficial for the assembly of the air duct housing 10 with other components and reduces interference between the air duct housing 10 and the surrounding components, with a simple structure.

[0077] 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 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.

[0078] The interface portions 13 protrude from the surface of the main body portion 12. The interface portions 13 are similar to flat tubular shapes. 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 two interface portions 13 can have the same shape, structure, dimensions, etc., thereby reducing the manufacturing cost of the air duct housing 10.

[0079] Specifically, one end of the intake pipe 70 is connected to one of the interface portions 13, and the other end of the intake pipe 70 is connected to the inner tank 1100. One end of the exhaust pipe 80 is connected to the other interface portion 13, and the other end of the exhaust pipe 80 is connected to the inner tank 1100.

[0080] It can be understood that the main body portion 12 and the two interface portions 13 both 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.

[0081] The evaporator 20 and the condenser 30 being arranged adjacent to each other within the main body portion 12 means that the evaporator 20 and the condenser 30 are arranged side by side within the main body portion 12 with a relatively small spacing, or that the evaporator 20 and the condenser 30 are arranged closely adjacent to each other within the main body portion 12.

[0082] Please refer to Figure 8 andFigure 9 , in some embodiments, two interface portions 13 extend upward from the main body portion 12 towards the side wall 1101 of the inner container 1100. The intake pipe 70 and the exhaust pipe 80 are located above the two interface portions 13, and the interface portions 13, the intake pipe 70, and the exhaust pipe 80 are located on the same side of the inner container 1100. In this way, the interface portions 13 can avoid the connection between the inner container 1100 and the intake pipe 70 and the exhaust pipe 80, which is beneficial to the assembly of the inner container 1100 with other components, reduces interference between the inner container 1100 and the surrounding components, and has a simple structure.

[0083] Specifically, as Figure 6 in the embodiment of, the interface portion 13 is formed with a ventilation port 131. The ventilation ports 131 of the two interface portions 13 both face upward, and the lower ends of the intake pipe 70 and the exhaust pipe 80 are respectively connected to the two interface portions 13 through the two ventilation ports 131. In this way, the ventilation ports 131 can allow gas to enter the air duct housing 10 from the intake pipe 70 from top to bottom, and then flow upward from inside the air duct housing 10 to the exhaust pipe 80.

[0084] Please refer to Figures 2-4 , in some embodiments, the main body portion 12 includes a top surface ********** 120, and the interface portion 13 is connected to the edge of the top surface 120. A receiving space 1201 is formed between the top surface 120 and the interface portion 13. The receiving space 1201 accommodates the corner portion where the bottom wall of the inner container 1100 is connected to the side wall 1101, and the top surface 120 is in contact with the bottom wall of the inner container 1100.

[0085] In this way, the receiving space 1201 formed between the top surface 120 and the interface portion 13 can accommodate the inner container 1100, and the interface portion 13 can avoid the connection between the inner container 1100 and the intake pipe 70 and the exhaust pipe 80, which is beneficial to the assembly of the inner container 1100 with other components, reduces interference between the inner container 1100 and the surrounding components, and has a simple structure.

[0086] Specifically, the connection between the interface portion 13 and the top surface 120 can be arc-shaped or bent. The edge where the interface portion 13 is connected to the top surface 120 is higher than the edge where the top surface 120 is in contact with the bottom wall of the inner container 1100. The receiving space 1201 is a space jointly surrounded by the side of the top surface 120 facing the interface portion 13 and the side of the interface portion 13 facing the top surface 120. The bottom wall of the inner container 1100 is in contact with the top surface 120, and the side wall of the inner container 1100 is in contact with the interface portion 13.

[0087] Please refer to Figure 8 and Figure 9 It should be noted that there is an unclear part in the text you provided (********** in ID=11). If you can clarify this part, I can provide a more accurate translation., in some embodiments, the main body 12 includes a first housing 121 and a second housing 122 detachably connected to the first housing 121, and the two interface portions 13 and the first housing 121 are of an integral structure. In this way, the first housing 121 and the second housing 122 are detachably connected, so that the evaporator 20 and the condenser 30 can be more conveniently installed into the main body 12, which is beneficial to improving the assembly efficiency of the heat pump drying system 1200. In addition, the interface portion 13 and the first housing 121 are of an integral structure, which can improve the sealing performance of the connection between the interface portion 13 and the first housing 121 and reduce the risk of air leakage in the diversion channel 11.

[0088] Specifically, the first housing 121 is located above the second housing 122. Therefore, the first housing 121 can be referred to as the upper housing, and the second housing 122 can be referred to as the lower housing. The first housing 121 and the second housing 122 can be connected by means of buckles, screws, etc. The interface portion 13 and the first housing 121 can be formed into an integral structure by an injection molding process.

[0089] Please refer to Figure 9 and Figure 10 , in some embodiments, a water receiving tray 14 is provided in the air duct housing 10, and the water receiving tray 14 is located below the evaporator 20. The evaporator 20 can condense the water vapor in the air to form condensed water, and the condensed water drips under the action of gravity. Therefore, the water receiving tray 14 can receive the condensed water formed by the evaporator 20 and reduce the risk of adverse effects caused by the condensed water remaining in other positions.

[0090] In one example, the water receiving tray 14 can be formed on the inner surface of the air duct housing 10, or rather, the water receiving tray 14 and the air duct housing 10 are of an integral structure. For example, the surface of the air duct housing 10 is recessed downward to form the water receiving tray 14.

[0091] In another example, the water receiving tray 14 and the air duct housing 10 are of a detachable structure, which enables both the air duct housing 10 and the water receiving tray 14 to be independently formed and then assembled together, making the shape of the air duct housing 10 simpler to reduce the manufacturing cost of the air duct housing 10. It can be understood that when the water receiving tray 14 and the air duct housing 10 are detachably connected, the water receiving tray 14 can be detached from the air duct housing 10 to pour out the condensed water in the water receiving tray 14.

[0092] Please refer to Figure 9 and Figure 10 , in some embodiments, the air duct housing 10 is provided with a drain port 15 communicating with the water receiving tray 14. In this way, the drain port 15 is conducive to discharging the condensed water received by the water receiving tray 14. In one example, the drain port 15 can be connected to the water cup 1300 of the washing appliance 1000 (such as Figure 1As shown, the condensed water in the water receiving tray 14 can be drained into the water cup 1300 of the washing appliance 1000, and then drained out of the washing appliance 1000 through the water cup 1300 of the washing appliance 1000. For example, the drain port 15 can be connected to a drain pipe, and a drain pump can be installed on the drain pipe. The drain pump can extract the condensed water in the water receiving tray 14 through the drain pipe.

[0093] In one example, in order to ensure smooth drainage of the drain port 15, the drain port 15 can be provided at a lower position of the water receiving tray 14.

[0094] Please refer to Figures 6-9 , in some embodiments, the heat pump drying system 1200 further includes a fan 40. The fan 40 is used to form an air flow in the diversion channel 11, and the fan 40 is installed on the outer side of the air duct housing 10. In this way, the fan 40 can provide power for the gas flow in the diversion channel 11. Specifically, the fan 40 can be an axial flow fan 40 or a centrifugal fan 40, and the fan 40 can be installed on the outer side of the second housing 122. When the fan 40 operates, a negative pressure is formed in the diversion channel 11, so that the gas circulates along the path of the inner tank 1100 - intake pipe 70 - air duct housing 10 - exhaust pipe 80 - inner tank 1100.

[0095] Please refer to Figures 6-8 , in some 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 provided 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. In this way, 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.

[0096] Specifically, the number of fans 40 can be two, three, four, etc. At least one fan 40 is installed on the main body 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. 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, so as to suck the air around the condenser 30 to make the gas flow. It is also possible 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.

[0097] At least one blower 40 is provided on the intake pipe 70, so that the intake pipe 70 can provide more space for the installation of the blower 40. At least a part of one blower 40 can 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 make the 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.

[0098] 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 diversion channel 11 of the heat pump drying system 1200 to provide power for the gas flow in the diversion channel 11.

[0099] Since the diversion channel 11 between the main body part 12 and the interface part 13 is non-linear, in order to reduce the resistance of gas flow, a centrifugal blower 40 is used, and the air outlet of the blower 40 faces the interface part 13, so that the gas can be directly discharged to the interface part 13.

[0100] Please refer to Figures 6-8 , in some embodiments, the heat pump drying system 1200 further includes a tray 50, and both the compressor 60 and the air duct housing 10 are installed on the tray 50 and located below the inner tank 1100. Along the depth direction X of the inner tank 1100, the compressor 60 and the air duct housing 10 are arranged at intervals. In this way, the compressor 60 and the air duct housing 10 form an integral body through the tray 50, which is beneficial to the installation of the heat pump drying system 1200 as a whole and improves the assembly efficiency of the washing appliance 1000.

[0101] Specifically, the tray 50 can be installed on the base 1400 of the washing appliance 1000. Since there is more installation space in the depth direction X of the inner tank 1100, arranging the compressor 60 and the air duct housing 10 at intervals along the depth direction X of the inner tank 1100 can rationally utilize the space of the washing appliance 1000 and reduce the interference between the compressor 60 and the air duct housing 10 and other components. The depth direction X of the inner tank 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0102] Please refer to Figure 8 , in some embodiments, the exhaust pipe 80 has a plurality of exhaust ports 81, and the plurality of exhaust ports 81 are arranged at intervals along the height direction of the inner tank 1100. In this way, the plurality of exhaust ports 81 of the exhaust pipe 80 are arranged at intervals along the height direction of the inner tank 1100, so that the exhaust ports 81 can discharge the dried hot air to different positions of the inner tank 1100, thereby achieving a better drying effect.

[0103] The number of exhaust ports 81 can be two, three, four, etc. The present application does not limit the specific number of exhaust ports 81.

[0104] Please refer to Figures 7-8 , in some embodiments, the exhaust pipe 80 has a first exhaust section 82 and a plurality of second exhaust sections 83. An exhaust port 81 is formed at the end of each second exhaust section 83, and the middle part of the second exhaust section 83 is bent upward in an arched shape. In this way, the first exhaust section 82 can introduce gas into the second exhaust section 83, and the middle part of the second exhaust section 83 is bent upward in an arched shape, so that the condensed water formed in the exhaust pipe 80 will not enter the inner tank 1100 again, which is beneficial to improving the drying efficiency of the washing appliance 1000. In addition, the middle part of the second exhaust section 83 being bent upward in an arched shape can also prevent the water in the inner tank 1100 from directly entering the exhaust pipe 80, improving the reliability of the normal operation of the heat pump drying system 1200.

[0105] In summary, please refer to Figure 1 , in one embodiment, after the washing appliance 1000 finishes washing and enters the drying mode, the fan 40 and the heat pump drying system 1200 start to work. The fan 40 causes the gas to circulate in the inner tank 1100, the intake pipe 70, the air duct housing 10, and the exhaust pipe 80. After the humid and hot gas passes through the evaporator 20, the evaporator 20 can cool the humid and hot air and form condensed water, and the condensed water drips into the water receiving tray 14; the air dried by the evaporator 20 is heated after passing through the condenser 30 and then enters the inner tank 1100 again to dry the tableware. In this way, the cycle is repeated to achieve the effect of drying the tableware.
