[0034] Please refer to Figure 1 , the washing appliance 1000 of the embodiment of the present application includes an inner container 1100 and a heat pump drying system 1200. The heat pump drying system 1200 is connected to the inner container 1100. The heat pump drying system 1200 is used to dry the humid and hot air flowing out of the inner container 1100 and heat the dried air so that the heated and 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. The washing appliance 1000 is, for example, a dishwasher.

[0035] It should be noted that the dried air mentioned above is relative to the humid and hot air in the inner container 1100, and does not mean that the air does not contain water vapor at all.

[0036] Please refer to Figures 1-4 , in some embodiments, the heat pump drying system 1200 includes a compressor 60, a throttling device 90, an evaporator 20, a condenser 30 and a duct component 100. The compressor 60, the condenser 30, the throttling device 90 and the evaporator 20 are connected in sequence to form a closed refrigerant circuit. The duct component 100 is formed with a diversion channel 11. The evaporator 20 is used to cool the gas flowing out of the inner container 1100 and passing through the intake pipe 70, and the condenser 30 is used to heat the gas flowing towards the exhaust pipe 80. The heat pump drying system 1200 further includes a first fan 41 and a second fan 42. The first fan 41 and the second fan 42 are arranged along the diversion direction of the diversion channel 11. Both the first fan 41 and the second fan 42 are used to form an air flow in the diversion channel 11.

[0037] In this way, the two fans 40 are arranged along the diversion direction of the diversion channel 11, so that the air flow flows more smoothly between the inner container and the diversion channel 11, which is beneficial to accelerating the air flow efficiency, thereby improving the drying efficiency of the heat pump drying system 1200 for the gas in the inner container 11,000.

[0038] Specifically, as Figures 2-4As shown, the inner tank 1100 forms a washing chamber 1104 with 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 can be arranged in the washing chamber 1104. A water cup 1300 is located below the washing chamber 1104. The water cup 1300 is used to collect and drain the water flow generated during washing and condensation.

[0039] The evaporator 20 is a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 operates, 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.

[0040] 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.

[0041] The condenser 30 is also a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 operates, the condenser 30 can heat, thereby absorbing the heat to heat 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 washing appliance 1000 again, the effect of drying objects such as tableware is achieved.

[0042] 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.

[0043] 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, 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 tank 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.

[0044] 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 tank 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 various 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.

[0045] The fan 40 can be an axial flow fan or a centrifugal fan. When the first fan 41 and the second fan 42 operate, they form air pressure in the diversion channel 11, enabling the gas to circulate along the path of the inner tank 1100 - the intake pipe 70 - the air duct housing 10 - the exhaust pipe 80 - the inner tank 1100.

[0046] As Figure 1 shown, in the embodiment of the present application, the evaporator 20 and the condenser 30 are arranged adjacent to each other with an interval in the diversion channel 11. Along the diversion 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 tank 1100 by the evaporator 20, and then heat it by the condenser 30 and return it to the inner tank 1100.

[0047] In this way, the evaporator 20 and the condenser 30 cooperate with each other to first cool and dry and then heat the air in the diversion channel 11, so that the washing appliance 1000 can utilize the heat pump drying system 1200 to achieve the effect of drying objects such as tableware. In some embodiments, the condenser 30 and the evaporator 20 are connected to the compressor 60 through a pipeline 61.

[0048] Please refer to Figures 1-4 In some embodiments, the air duct component 100 further includes an air duct housing 10, an intake pipe 70, and an exhaust pipe 80. The evaporator 20 and the condenser 30 are spaced apart and disposed in the air duct housing 10. The air duct housing 10 is installed on the base 1400 of the washing appliance 1000 and is located below the inner tank 1100. Both the intake pipe 70 and the exhaust pipe 80 are connected to the air duct housing 10. The intake end of the intake pipe 70 is connected to the inner tank 1100, and the exhaust end of the exhaust pipe 80 is connected to the inner tank 1100. The first blower 41 is installed on the air duct housing 10, and the second blower 42 is installed at the intake end of the intake pipe 70.

[0049] In this way, the base 1400 of the washing appliance 1000 can provide support for the air duct housing 10 and the inner tank 1100, thereby making the installation of the air duct component 100 and the inner tank 1100 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. In addition, the second blower 42 is installed at the intake end of the intake pipe 70, which is closer to the washing chamber 1104 of the inner tank 1100 and is more conducive to extracting the gas in the inner tank 1100 into the diversion channel 11.

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

[0051] Specifically, the air duct housing 10 is used for ventilation. The air duct housing 10 as a whole can be made of materials such as plastic that are easy to mold, making the air duct housing 10 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 can cooperate more closely with the surrounding components. The air duct housing 10 communicates with the inner tank 1100. The air duct housing 10 being located below the inner tank 1100 can mean that at least part of the air duct housing 10 is lower than the bottom of the inner tank 1100.

[0052] The intake pipe 70 and the exhaust pipe 80 can at least partially adhere to the 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 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.

[0053] The blower 40 can be installed on the air duct housing 10 or the intake end of the intake pipe 70 by means of screws. In this way, the two blowers 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.

[0054] The first blower 41 is installed on the air duct housing 10, so that the air duct housing 10 can provide a larger space for the installation of the first blower 41. Exemplarily, the first blower 41 can be installed on the outside of the air duct housing 10 or at the installation position inside the air duct housing 10.

[0055] Please refer to Figure 5 , in some embodiments, the first blower 41 is a centrifugal blower. The first blower 41 sucks in gas from the air duct housing 10 along its axial direction and discharges the gas in the tangential direction to the exhaust pipe 80. Since the diversion channel 11 between the air duct housing 10 and the exhaust pipe 80 is non-linear, in order to reduce the resistance of gas flow, the first blower 41 adopts a centrifugal blower, and the air outlet of the first blower 41 faces the exhaust pipe 80, so that the gas can be directly discharged to the exhaust pipe 80.

[0056] Specifically, the first blower 41 includes an impeller and a motor. After the first blower 41 is started, a negative pressure can be formed on the side facing the condenser 30, thereby sucking in the air around the condenser 30. The air enters the impeller axially, and the gas changes to the tangential direction when flowing through the impeller and then flows out. Viewed from the front of the motor side, according to the rotation direction of the impeller, the centrifugal blower can be divided into a left-rotating blower and a right-rotating blower.

[0057] The second blower 42 is arranged at the intake end of the intake pipe 70, so that the intake end of the intake pipe 70 can provide a larger space for the installation of the second blower 42. At least a part of the second blower 42 can be located in the intake pipe 70 and upstream of the evaporator 20. After the second blower 42 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.

[0058] Please refer to Figures 2-4, in some embodiments, the inner container 1100 includes a top wall 1105 and a side wall 1101 connected to the top wall 1105. The intake end of the intake pipe 70 is connected to the top wall 1105, and the exhaust end of the exhaust pipe 80 is connected to the side wall 1101. Since the humid and hot air in the inner container 1100 flows upward, and objects such as tableware are located below the top of the inner container 1100, the intake end of the intake pipe 70 is connected to the top wall 1105, and the exhaust end of the exhaust pipe 80 is connected to the side wall 1101. In this way, 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, so that the second blower 42 can more easily extract the humid and hot air in the inner container 1100 through the intake pipe 70, and the exhaust pipe 80 can discharge the dry hot air to a position below the top of the inner container 1100, thereby better drying objects such as tableware.

[0059] Specifically, as Figure 3 and Figure 4 shown, the top wall 1105 of the inner container 1100 may be provided with a first through hole 1102, and the side wall 1101 of the inner container 1100 may be provided with a second through hole 1103. 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 first through hole 1102 and the second through hole 1103 are holes penetrating the side wall 1101 of the inner container 1100. The second through hole 1103 may be provided on the left side wall 1101, the right side wall 1101 or the rear side wall 1101 of the inner container 1100.

[0060] The intake end of the intake pipe 70 being docked 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 the first through hole 1102 can be covered on the outer surface of the top wall 1105 of the inner container 1100. Similarly, the exhaust end of the exhaust pipe 80 being docked 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 the second through hole 1103 can be covered on the outer surface of the side wall 1101 of the inner container 1100.

[0061] In some embodiments, the inner container 1100 includes a top wall 1105 and a side wall 1101 connected to the top wall 1105. A first through hole 1102 and a second through hole 1103 spaced apart from the first through hole 1102 are provided on the same side wall 1101 in the width direction Y 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. This makes it more convenient for the intake pipe 70 and the exhaust pipe 80 to be combined with the inner container 1100, simplifies the structure of the air duct component 100, is beneficial to improving the reliability of the washing appliance 1000 and has a lower manufacturing cost.

[0062] Specifically, the first through-hole 1102 and the second through-hole 1103 are holes that penetrate the same side wall 1101 of the inner tank 1100 in the width direction Y thereof. For example, the first through-hole 1102 and the second through-hole 1103 can be provided on the left side wall 1101 or the right side wall 1101 of the inner tank 1100 simultaneously. The width direction Y of the inner tank 1100 is the direction in which the opening of the washing chamber 1104 extends to the left and right sides.

[0063] In some embodiments, the power of the first blower 41 is greater than that of the second blower 42. Since the second blower 42 is closer to the washing chamber 1104 of the inner tank 1100, the second blower 42 can extract the gas in the inner tank 1100 with a smaller power, which is beneficial to making the washing appliance 1000 more miniaturized; while the first blower 41 is farther from the washing chamber 1104 of the inner tank 1100 than the second blower 42. In order to provide sufficient flow power for the gas, the first blower 41 with a larger power can improve the smoothness of the gas flowing in the diversion channel 11.

[0064] Please refer to Figures 1-5 , 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 tank 1100. This makes it more convenient to combine the evaporator 20, the condenser 30, the intake pipe 70 and the exhaust pipe 80 with the inner tank 1100, simplifies the structure of the air duct component 100, further improves the reliability of the washing appliance 1000 and reduces the manufacturing cost.

[0065] Specifically, it can be that the evaporator 20, the condenser 30, the intake pipe 70 and the exhaust pipe 80 are all located on the same side wall 1101 of the inner tank 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 tank 1100.

[0066] 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 1106 of the inner tank 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall 1106 of the inner tank 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 tank 1100, simplifies the structure of the air duct component 100, further improves the reliability of the washing appliance 1000 and reduces the manufacturing cost.

[0067] Specifically, the intake pipe 70 and the exhaust pipe 80 can be located on the right side wall 1101 of the inner tank 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall 1106 on the right side of the inner tank 1100.

[0068] 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 tank 1100. For example, the evaporator 20 and the intake pipe 70 are located on the left side of the inner tank 1100, and the condenser 30 and the exhaust pipe 80 are located on the right side of the inner tank 1100. Exemplarily, the evaporator 20 and the intake pipe 70 may be located on the left side wall 1101 of the inner tank 1100, and the condenser 30 and the exhaust pipe 80 may be located on the right side wall 1101 of the inner tank 1100. Alternatively, the intake pipe 70 is located on the left side wall 1101 of the inner tank 1100, the evaporator 20 is located below the bottom wall on the left side of the inner tank 1100, the exhaust pipe 80 is located on the right side wall 1101 of the inner tank 1100, and the condenser 30 is located below the bottom wall on the right side of the inner tank 1100.

[0069] It should be noted that the left and right sides of the inner tank 1100 described in this application refer to taking the opening of the inner tank 1100 as the front, and the plane at 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 tank 1100, and the right side of the reference plane is the right side of the inner tank 1100.

[0070] Please refer to Figures 2-3 , in some embodiments, the intake pipe 70 and the exhaust pipe 80 are arranged side by side along the depth direction X of the inner tank 1100. Since there is more installation space in the depth direction X of the inner tank 1100, arranging the intake pipe 70 and the exhaust pipe 80 side by side along the depth direction X of the inner tank 1100 can reasonably utilize the space of the washing appliance 1000 and reduce the interference between the intake pipe 70 and the exhaust pipe 80 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.

[0071] Please refer to Figures 4-6 , 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. The two interface portions 13 are both connected to the same side of the main body portion 12 and are spaced apart. 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 and is formed with an installation position 132 for installing the first blower 41. The evaporator 20 and the condenser 30 are arranged adjacent to each other in the main body portion 12.

[0072] In this way, the air duct housing 10 forms the main body portion 12 and the interface portions 13 according to different functions, so that the air duct housing 10 can meet the requirements for installing the evaporator 20 and the condenser 30 and can realize the ventilation function. In addition, both of the two interface portions 13 are connected to the same side of the main body portion 12, so that the air intake and air outlet of the air duct housing 10 are both on the same side. This is beneficial to the assembly of the air duct housing 10 with other components, reduces the interference between the air duct housing 10 and the surrounding components, and has a simple structure.

[0073] Specifically, the volume of the main body portion 12 is greater than that of the interface portion 13, such that the main body can accommodate the evaporator 20 and the condenser 30, and also makes it easier for the interface portion 13 to be connected to other pipe fittings. The overall shape of the main body portion 12 is generally square. The evaporator 20 and the condenser 30 can be fixed inside the main body portion 12 by means of snap connection, threaded connection, etc.

[0074] The interface portion 13 protrudes from the surface of the main body portion 12. The interface portion 13 is similar to a flat tube shape. The interface portion 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.

[0075] 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.

[0076] It can be understood that the main body portion 12 and the two interface portions 13 both form a part of the diversion 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.

[0077] The adjacent arrangement of the evaporator 20 and the condenser 30 inside the main body portion 12 means that the evaporator 20 and the condenser 30 are arranged side by side in the main body portion 12 with a relatively small distance therebetween, or the evaporator 20 and the condenser 30 are arranged closely in the main body portion 12.

[0078] Please refer to Figure 7 and Figure 8 , in some embodiments, the two interface portions 13 extend upward from the side wall 1101 of the main body portion 12 toward the inner tank 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 tank 1100. In this way, the interface portions 13 can avoid the connection between the inner tank 1100 and the intake pipe 70 and the exhaust pipe 80, which is beneficial to the assembly of the inner tank 1100 with other components, reduces the interference between the inner tank 1100 and the surrounding components, and has a simple structure.

[0079] Specifically, as in Figure 7 the embodiment, the interface portion 13 is formed with a vent hole 131. The vent holes 131 of the two interface portions 13 both face upward. 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 vent holes 131. In this way, the vent holes 131 can allow the gas to enter the air duct housing 10 from top to bottom through the intake pipe 70, and then flow upward out of the air duct housing 10 to the exhaust pipe 80.

[0080] Please refer toFigures 3-4 In some embodiments, the main body portion 12 includes a top surface 120. The interface portion 13 is connected to the edge of the top surface 120. An accommodation space 1201 is formed between the top surface 120 and the interface portion 13. The accommodation space 1201 accommodates the corner portion where the bottom wall 1106 of the inner container 1100 is connected to the side wall 1101, and the top surface 120 is in contact with the bottom wall 1106 of the inner container 1100.

[0081] Thus, the accommodation space 1201 formed between the top surface 120 and the interface portion 13 can accommodate the inner container 1100. The interface portion 13 can avoid the connection between the inner container 1100 and the intake pipe 70 and the exhaust pipe 80. This 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.

[0082] 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 accommodation space 1201 is a space jointly formed 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.

[0083] Please refer to Figures 6-8 In some embodiments, the main body portion 12 includes a first shell 121 and a second shell 122 detachably connected to the first shell 121. The two interface portions 13 and the first shell 121 are of an integral structure. Thus, the first shell 121 and the second shell 122 are detachably connected, enabling the evaporator 20 and the condenser 30 to be more conveniently installed into the main body portion 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 shell 121 are of an integral structure, which can improve the sealing performance of the connection between the interface portion 13 and the first shell 121 and reduce the risk of air leakage in the diversion channel 11.

[0084] Specifically, the first shell 121 is located above the second shell 122. Therefore, the first shell 121 can be referred to as the upper shell, and the second shell 122 can be referred to as the lower shell. The first shell 121 and the second shell 122 can be connected by means such as snap fasteners and screws. The interface portion 13 and the first shell 121 can be formed into an integral structure by an injection molding process.

[0085] Please refer to Figure 7 and Figure 8In some embodiments, a water tray 14 is provided within the air duct housing 10 and is located below the evaporator 20. The evaporator 20 condenses moisture in the air into condensed water, which then drips under the action of gravity. Therefore, the water tray 14 can receive the condensed water formed by the evaporator 20, reducing the risk of the condensed water being deposited elsewhere and causing adverse effects.

[0086] In one example, the water receiving tray 14 can be formed on the inner surface of the air duct housing 10, or in other words, the water receiving tray 14 is an integral structure with the air duct housing 10. For example, the surface of the air duct housing 10 is recessed downward to form the water receiving tray 14.

[0087] In another example, the water receiving tray 14 and the air duct housing 10 are detachable structures, so that the air duct housing 10 and the water receiving tray 14 can be independently molded and then assembled together, making the shape of the air duct housing 10 simpler and reducing the manufacturing cost of the air duct housing 10. It is understood that when the water receiving tray 14 and the air duct housing 10 are detachably connected, the water receiving tray 14 can be removed from the air duct housing 10 to pour out the condensed water in the water receiving tray 14.

[0088] See also Figure 7 and Figure 8 In some embodiments, the air duct housing 10 is provided with a drain port 15 connected to the water receiving tray 14. In this way, the drain port 15 is conducive to draining 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 (such as the washing machine 1000) of the washing machine 1000. Figure 1 As shown, the condensed water in the water receiving tray 14 can be drained into the water cup 1300 of the washing machine 1000, and then drained out of the washing machine 1000 through the water cup 1300 of the washing machine 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 to pump out the condensed water in the water receiving tray 14 through the drain pipe.

[0089] In one example, in order to facilitate drainage through the drain port 15 , the drain port 15 may be disposed at a lower portion of the water receiving tray 14 .

[0090] See also Figures 4-6 In some embodiments, the heat pump drying system 1200 further includes a tray 50, on which the compressor 60 and the air duct housing 10 are mounted. The compressor 60 and the air duct housing 10 are spaced apart along the depth direction X of the inner container 1100. Thus, the compressor 60 and the air duct housing 10 are integrated by the tray 50, facilitating the integrated installation of the heat pump drying system 1200 and improving the assembly efficiency of the washing appliance 1000.

[0091] 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 container 1100, the compressor 60 and the air duct housing 10 are arranged at intervals along the depth direction X of the inner container 1100, which can reasonably utilize the space of the washing appliance 1000 and reduce the interference between the compressor 60, the air duct housing 10 and other components.

[0092] Please refer to Figure 1 and Figure 6 , in some embodiments, the washing appliance 1000 includes at least two bowl baskets 1107 disposed in the inner container 1100. The at least two bowl baskets 1107 are arranged at intervals along the height direction of the inner container 1100. The exhaust end of the exhaust pipe 80 has at least two exhaust ports 81. The at least two exhaust ports 81 are arranged at intervals along the height direction of the inner container 1100. The exhaust ports 81 correspond to the bowl baskets 1107 one by one, and the exhaust ports 81 face the bowl baskets 1107.

[0093] In this way, the gas discharged from the at least two exhaust ports 81 can flow to the corresponding at least two bowl baskets 1107, achieving the effect of drying items such as tableware in the corresponding bowl baskets 1107.

[0094] Specifically, the bowl basket 1107 can be a square frame. The bottom and sides of the bowl basket 1107 are both hollow structures, enabling gas to enter the bowl basket 1107 to dry items such as tableware in the bowl basket 1107. The height of the bowl basket 1107 in the inner container 1100 is the same as the height of the corresponding exhaust port 81 in the inner container 1100. For example, there are two bowl baskets 1107 in the inner container 1100, and the exhaust end of the exhaust pipe 80 has two exhaust ports 81. One bowl basket 1107 and the exhaust port 81 are at the first height of the inner container 1100, and the other bowl basket 1107 and the exhaust port 81 are at the second height of the inner container 1100.

[0095] 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 container 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 container 1100, so that the exhaust ports 81 can discharge the dried hot air to different positions in the inner container 1100, thereby achieving a better drying effect.

[0096] The number of the exhaust ports 81 can be two, three, four, etc. The present application does not limit the specific number of the exhaust ports 81.

[0097] Please refer to Figures 5-6, 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 each end of the second exhaust section 83, and the middle part of the second exhaust section 83 is bent upward in an arch. 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 arch, 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 is bent upward in an arch, which can also prevent the water in the inner tank 1100 from directly entering the exhaust pipe 80, and improve the reliability of the normal operation of the heat pump drying system 1200.

[0098] In summary, please refer to Figure 1 and Figure 7 , in one embodiment, after the washing appliance 1000 finishes washing and enters the drying mode, the second fan 42 can be started first to form a relatively small negative pressure in the washing chamber 1104, reducing the risk of the humid and hot air leaking from the inner tank 1100 to other parts of the washing appliance 100 and forming condensed water. After that, the first fan 41 and the compressor 60 start to work. The first fan 41 and the second fan 42 make the gas 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.
