[0037] See also Figure 1-Figure 3 The washing appliance 1000 of the embodiment of the present application includes an inner tank 1100, a base 1400, a water cup 1300, a heat pump system 1200, and an air duct component 100. The inner tank 1100 is provided with a washing chamber 1104. The base 1400 is located below the inner tank 1100. The water cup 1300 is mounted on the base 1400. The heat pump system 1200 includes a compressor 60, a condenser 30, a throttling device 90, and an evaporator 20, which are sequentially connected to form a closed refrigerant circuit. The compressor 60, condenser 30, throttling device 90 and evaporator 20 are all arranged in the accommodating space 1410 of the base 1400 and are all located on one side of the water cup 1300. The air duct component 100 includes an air duct shell 10 arranged on the base 1400. The evaporator 20 and the condenser 30 are arranged at intervals in the air duct shell 10. The evaporator 20 is used to cool the gas flowing out of the inner tank 1100, and the condenser 30 is used to heat the gas flowing into the inner tank 1100.

[0038] In this way, by integrating the compressor 60, condenser 30, throttling device 90 and evaporator 20 on one side of the base 1400, the heat pump system 1200 occupies less space on the base 1400, and the modular design of the heat pump system 1200 can reduce the number of parts that need to be assembled in the washing appliance 1000 when the washing appliance 1000 is assembled, improve the assembly effect of the washing appliance 1000, and thus reduce the manufacturing cost of the washing appliance 1000.

[0039] Specifically, washing appliance 1000 is primarily used for washing various types of tableware. An inner container 1100 serves as the main structure of washing appliance 1000. Inner container 1100 defines a washing chamber 1104 with an opening, through which tableware and other objects can be placed. Washing chamber 1104 may include a bracket for holding and securing the tableware, and a water cup 1300 positioned beneath the bracket. Water cup 1300 is used to collect and drain water generated during the washing and condensation processes. Washing appliance 1000 is, for example, a dishwasher.

[0040] The base 1400 is used to support components such as the inner tank 1100, the heat pump system 1200 and the air duct component 100. The top surface of the base 1400 extends downward to form a receiving space 1410, and components such as the inner tank 1100, the heat pump system 1200 and the air duct component 100 are arranged in the receiving space 1410.

[0041] The water cup 1300 has a water inlet 1310, which is equipped with a filter. The water inlet 1310 is located on the side of the water cup 1300 facing the inner container 1100 and is arranged in a groove-like shape. In this embodiment, the shape of the water inlet 1310 is circular, but it is not limited to a variety of shapes, such as oval or square. The compressor 60, condenser 30, throttling device 90, and evaporator 20 can be located on the left or right side of the water cup 1300.

[0042] Heat pump system 1200 is used to dry the hot and humid air flowing out of inner liner 1100 and heat the dried air, allowing the heated, dry air to flow back into inner liner 1100. This cycle continues, achieving the effect of drying dishes and other objects. It should be noted that the dried air mentioned above refers to the hot and humid air in inner liner 1100, and does not mean that the air is completely free of moisture.

[0043] The evaporator 20 is a heat exchanger in the heat pump system 1200. When the heat pump system 1200 is operating, the evaporator 20 can cool the air, thereby absorbing heat from the air surrounding the evaporator 20 to lower the temperature of the surrounding air. This allows the gas flowing through the evaporator 20 to condense into condensed water, thereby drying the air.

[0044] The condenser 30 is also a heat exchanger in the heat pump system 1200. When the heat pump system 1200 is operating, the condenser 30 generates heat, thereby releasing heat to the air surrounding the condenser 30 to raise the temperature of the surrounding air. This allows the air flowing through the condenser 30 to re-enter the inner tank 1100 of the washing appliance 1000, thereby drying items such as dishes.

[0045] The condenser 30 and the evaporator 20 can be connected to the compressor 60 via a pipe 61. The compressor 60, condenser 30, throttling device 90, and evaporator 20 are the main components of the heat pump system 1200 of the washing machine 1000. They are connected in sequence to form a closed refrigerant circuit, allowing the refrigerant, which serves as a refrigerant, to circulate in the sealed refrigerant circuit formed by the compressor 60, condenser 30, throttling device 90, and evaporator 20. The four components work together to enable the heat pump system 1200 to achieve the effect of drying objects such as dishes. When the heat pump system 1200 is in the drying phase, the compressor 60 operates, pumping high-temperature, 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, becomes low-temperature, low-pressure refrigerant, flows into the evaporator 20, exchanges heat with the air, and evaporates. The refrigerant 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 reenters the inner tank 1100 of the washing machine 1000. The throttling device 90 may be an expansion valve. Furthermore, the throttling device 90 may be an electronic expansion valve.

[0046] The heat pump system 1200 can be directly or indirectly connected to the base 1400. For example, the heat pump system 1200 can be fixed to a base plate, which is then mounted on the base 1400. This allows the components of the heat pump system 1200 to be integrated, making it easier to disassemble and install the entire heat pump system 1200.

[0047] The evaporator 20 and the condenser 30 are arranged in the air duct housing 10, so that the air duct housing 10, the evaporator 20 and the condenser 30 can form an integral module, which is convenient for assembly to form the washing appliance 1000 and helps to reduce the manufacturing cost of the washing appliance 1000.

[0048] The air duct component 100 includes a heat exchange module with a heat exchange function. The heat exchange module has at least some heat exchange components of the heat pump system 1200 of the washing appliance 1000, that is, the heat exchange module includes at least an evaporator 20 and a condenser 30, so that the washing appliance 1000 can achieve the effect of drying items such as tableware through the air duct component 100.

[0049] The air duct housing 10 is used for ventilation. The entire air duct housing 10 can be made of easily moldable materials such as plastic, making it easy to manufacture. The air duct housing 10 can be configured with a specific external structure based on the installation location of the air duct component 100, so that the air duct component 100 fits more compactly with surrounding components. The air duct housing 10 is in communication with the inner liner 1100.

[0050] See also Figure 2In some embodiments, the washing machine 1000 includes a breather 1600, which is disposed on one side of the inner container 1100, while the air inlet duct 70 and the exhaust duct 80 are disposed on the opposite side of the inner container 1100. This reduces interference of the breather 1600 with the connection between the air inlet duct 70 and the exhaust duct 80 and the inner container 1100, simplifies the structure of the air duct component 100, further improves the reliability of the washing machine 1000, and reduces manufacturing costs.

[0051] Specifically, the breather 1600 is equipped with a flow meter that can calculate the amount of water entering. The breather 1600 can provide a limited flow of water to the water softener 1500 for softening for washing, while also preventing backflow of water in the inner liner 1100. The breather 1600 also connects the interior and exterior of the inner liner 1100, balancing the internal and external air pressures of the inner liner 1100. This significantly reduces the manufacturing cost and the operating and maintenance costs of the washing appliance 1000, while ensuring stable, safe, and reliable operation. The breather 1600 can be fixed to the side wall 1101 of the inner liner 1100. It should be noted that the breather 1600 can be purchased commercially or directly manufactured by a person skilled in the art.

[0052] The respirator 1600 may be disposed on the left side of the inner liner 1100 , and the air inlet pipe 70 and the exhaust pipe 80 may be disposed on the right side of the inner liner 1100 .

[0053] See also Figure 2 In some embodiments, the washing machine 1000 includes a water softener 1500, which is disposed on the base 1400. The compressor 60 and the air duct housing 10 are arranged in a front-to-back arrangement on one side of the base 1400, with the water softener 1500 disposed on the side of the base 1400 opposite the air duct housing 10. This reduces interference of the water softener 1500 with the connection between the compressor 60 and the air duct housing 10 and the base 1400, thus simplifying the structure of the washing machine 1000, further improving the reliability of the washing machine 1000, and reducing manufacturing costs.

[0054] Specifically, the water softener 1500 can be set on the left side of the base 1400, the compressor 60 and the air duct housing 10 can be set on the right side of the base 1400, the air duct housing 10 can be set on the front side of the base 1400, and the compressor 60 can be set on the rear side of the base 1400.

[0055] Water softener 1500 is an ion exchange water softener that operates in both operational and regenerative processes. It uses sodium cation exchange resin to remove calcium and magnesium ions from water, reducing raw water hardness and softening hard water, thereby preventing carbonate scaling in pipes, containers, and boilers. This significantly reduces investment costs while ensuring smooth production. Two common water softening technologies are used in water softeners 1500: one uses ion exchange resin to remove calcium and magnesium ions from water, reducing water hardness; the other is nanocrystal TAC technology, or Template Assisted Crystallization. This utilizes the high energy generated by nanocrystals to pack free calcium, magnesium, and bicarbonate ions into nanoscale crystals, thereby preventing scale formation from the free ions. The water softener 1500 can be connected to the base 1400 via a water inlet pipe. In one embodiment, the water softener 1500 can be fixed to the sidewall 1101 of the inner tank 1100. It should be noted that the water softener 1500 can be purchased on the market, or can be directly processed and manufactured by those skilled in the art.

[0056] See also Figure 2 In some embodiments, the water cup 1300 is located in the middle of the base 1400, on the center line of the base 1400 extending in the front-to-back direction, the water softener 1500 and the respirator 1600 are located on the left side of the center line, and the heat pump system 1200 and the air duct component 100 are located on the right side of the base 1400.

[0057] Thus, water cup 1300 is located in the center of base 1400, concentrating the weight of the collected water there, making washing appliance 1000 less likely to tip over and maintaining a more stable structure. Furthermore, water softener 1500, breather 1600, heat pump system 1200, and air duct component 100 are located on both sides of base 1400, reducing interference between water softener 1500 and breather 1600 and the connection between heat pump system 1200 and air duct component 100 and base 1400. This simplifies the structure of washing appliance 1000, further improving its reliability and reducing manufacturing costs.

[0058] Specifically, the water cup 1300 is located in the middle position of the base 1400, which may mean that the water cup 1300 is located on the center line of the base 1400 extending in the front-to-back direction, or it may mean that the water cup 1300 is located on the center line of the base 1400 extending in the left-to-right direction, or it may mean that the water cup 1300 is located at the intersection of the center line of the base 1400 extending in the front-to-back direction and the center line extending in the left-to-right direction.

[0059] See also Figure 2In some embodiments, the washing appliance 1000 includes a control system 1700 , which is disposed on the front side of the base 1400 . The control system 1700 is at least partially located between the air duct housing 10 and the water softener 1500 .

[0060] In this way, the control system 1700 is used to control the operating status of the washing appliance 1000. The control system 1700 is arranged on the front side of the base 1400, which is convenient for setting parameters of the control system 1700. The control system 1700 is at least partially located between the air duct housing 10 and the water softener 1500, which is convenient for the control system 1700 to control the heat pump system 1200 and the water softener 1500.

[0061] Specifically, the control system 1700 can control water temperature, water level, washing time, drying time, etc. For example, the washing appliance 1000 includes a temperature sensor. During the continuous circulation and heating of the fluid, the temperature sensor can detect the temperature of the fluid in real time. When the fluid reaches the set temperature, the temperature sensor can feed back the temperature signal to the control system 1700 to determine whether to stop heating.

[0062] The front side of the base 1400 can be the side of the base 1400 facing the opening of the inner tank 1100, and the control system 1700 can be at least partially located between the air duct housing 10 and the water softener 1500. The control system 1700 can be partially located between the air duct housing 10 and the water softener 1500, or the control system 1700 can be completely located between the air duct housing 10 and the water softener 1500. The air duct housing 10 and the water softener 1500 can be located on the left and right sides of the base 1400, respectively.

[0063] See also Figure 3-Figure 5 In some embodiments, the air duct component 100 further includes an air inlet pipe 70 and an exhaust pipe 80 , both of which are connected to the air duct housing 10 , and the air duct housing 10 , the air inlet pipe 70 , and the exhaust pipe 80 together form a guide channel 11 .

[0064] In this way, the air inlet pipe 70 can guide the gas in the inner tank 1100 into the air duct shell 10, and the exhaust pipe 80 can guide the gas after passing through the evaporator 20 and the condenser 30 in sequence into the inner tank 1100, thereby realizing the circulation of gas between the air duct component 100 and the inner tank 1100.

[0065] The air inlet pipe 70 and the air duct housing 10 can be an integrally formed structure or a split and detachable structure. Similarly, the exhaust pipe 80 and the air duct housing 10 can be an integrally formed structure or a split and detachable structure.

[0066] The evaporator 20 is generally flat and can be placed vertically, or in other words, the thickness of the evaporator 20 is arranged generally horizontally. The thickness of the evaporator 20 is generally parallel to the central axis of the guide channel 11, so that the contact area between the gas in the guide channel 11 and the evaporator 20 is increased, which is conducive to improving the drying effect of the air flowing through the evaporator 20.

[0067] The condenser 30 is generally flat and can be placed vertically, or in other words, the thickness of the condenser 30 is generally horizontal. The thickness of the condenser 30 is generally parallel to the central axis of the guide channel 11, so that the contact area between the gas in the guide channel 11 and the condenser 30 is larger, which is conducive to improving the heating effect of the air flowing through the condenser 30.

[0068] See also Figure 4 and Figure 5 In some embodiments, the inner liner 1100 is provided with a first through hole 1102 and a second through hole 1103, the first through hole 1102 and the second through hole 1103 are arranged at intervals, the air intake pipe 70 and the exhaust pipe 80 are arranged on the same side wall 1101 of the inner liner 1100, the air intake end of the air intake pipe 70 is connected to the first through hole 1102, and the exhaust end of the exhaust pipe 80 is connected to the second through hole 1103.

[0069] In this way, the air intake pipe 70 and the exhaust pipe 80 are arranged on the same side wall 1101, and the air intake end of the air intake pipe 70 is connected to the first through hole 1102, and the exhaust pipe 80 is formed with an exhaust end connected to the second through hole 1103. In this way, the air intake pipe 70 and the exhaust pipe 80 can be more conveniently combined with the inner tank 1100, making the structure of the air duct component 100 simpler, which is conducive to improving the reliability of the washing appliance 1000 and lowering the manufacturing cost.

[0070] Specifically, the first through hole 1102 and the second through hole 1103 are holes that pass through the side wall 1101 of the inner liner 1100. The first through hole 1102 and the second through hole 1103 can be provided on the same side wall 1101 of the inner liner 1100, or on different side walls 1101 of the inner liner 1100. For example, the first through hole 1102 and the second through hole 1103 can be provided on the left side wall 1101, the right side wall 1101, the rear side wall 1101, or the top wall of the inner liner 1100, or can be provided on the left side wall 1101, the right side wall 1101, the rear side wall 1101, or the top wall of the inner liner 1100. For example, the first through hole 1102 is provided on the top wall of the inner liner 1100, and the second through hole 1103 is provided on the left side wall 1101 of the inner liner 1100.

[0071] See also Figure 4 and Figure 5In some embodiments, the height of the first through hole 1102 is higher than the height of the second through hole 1103. Since the hot and humid air in the inner container 1100 flows upward, and objects such as tableware are located below the top of the inner container 1100, in order to achieve a proper drying effect, in some embodiments, the height of the first through hole 1102 is higher than the height of the second through hole 1103. 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. This allows the intake pipe 70 to more easily extract the hot and humid air in the inner container 1100, 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.

[0072] See also Figure 3-Figure 5 In some embodiments, the evaporator 20, condenser 30, air inlet pipe 70, and exhaust pipe 80 are all located on the same side of the inner container 1100. This allows the evaporator 20, condenser 30, air inlet pipe 70, and exhaust pipe 80 to be more conveniently integrated with the inner container 1100, making the structure of the air duct component 100 simpler, further improving the reliability of the washing appliance 1000, and reducing the manufacturing cost.

[0073] Specifically, the evaporator 20, condenser 30, air inlet pipe 70 and exhaust pipe 80 may all be located on the same side wall 1101 of the inner tank 1100. For example, the evaporator 20, condenser 30, air inlet pipe 70 and exhaust pipe 80 may all be located on the left side wall 1101, right side wall 1101 or rear side wall 1101 of the inner tank 1100.

[0074] See also Figure 3-Figure 5 In some embodiments, the air inlet duct 70 and the exhaust duct 80 are mounted on the side wall 1101 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 air inlet duct 70 and the exhaust duct 80. This can reduce interference between the evaporator 20 and the condenser 30 and the connection between the air inlet duct 70 and the exhaust duct 80 and the inner container 1100, simplifying the structure of the air duct component 100, further improving the reliability of the washing appliance 1000, and reducing manufacturing costs.

[0075] Specifically, the air inlet pipe 70 and the air outlet 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 .

[0076] In one embodiment, the evaporator 20, the air inlet 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 air inlet 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. For example, the evaporator 20 and the air inlet 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. Alternatively, the air inlet pipe 70 may be located on the left side wall 1101 of the inner container 1100, the evaporator 20 may be located below the bottom wall of the left side of the inner container 1100, the exhaust pipe 80 may be located on the right side wall 1101 of the inner container 1100, and the condenser 30 may be located below the bottom wall of the right side of the inner container 1100.

[0077] It should be noted that the left and right sides of the inner liner 1100 described in this application refer to the surface with the opening of the inner liner 1100 as the front and 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 liner 1100, and the right side of the reference plane is the right side of the inner liner 1100.

[0078] See also Figure 6-Figure 8 In some embodiments, the air duct housing 10 includes a main body 12 and two interface portions 13, both of which are connected to the main body 12, and both of which are connected to the same side of the main body 12 and are arranged at intervals, one of which is connected to the air inlet pipe 70, and the other is connected to the exhaust pipe 80, and the evaporator 20 and the condenser 30 are adjacently arranged in the main body 12.

[0079] In this way, the air duct housing 10 is formed with a main body 12 and an interface portion 13 according to different functions, allowing the air duct housing 10 to meet the requirements of installing the evaporator 20 and the condenser 30, while also achieving ventilation. In addition, both interface portions 13 are connected to the same side of the main body 12, so that the air inlet and outlet of the air duct housing 10 are located on the same side. This facilitates the assembly of the air duct housing 10 with other components, reduces interference between the air duct housing 10 and surrounding components, and simplifies the structure.

[0080] Specifically, the volume of the main body 12 is larger than that of the interface 13, allowing the main body to accommodate the evaporator 20 and condenser 30 and facilitating connection of the interface 13 with other pipes. The main body 12 is generally block-shaped. The evaporator 20 and condenser 30 can be secured within the main body 12 by means of a snap-fit, threaded connection, or other methods.

[0081] The interface portion 13 protrudes from the surface of the main body 12. The interface portion 13 is similar to a flat tube. The interface portion 13 can be located on one side of the main body 12 in the length direction or the width direction. The shape, structure, and size of the two interface portions 13 can be identical, thereby reducing the manufacturing cost of the air duct housing 10.

[0082] Specifically, one end of the air inlet pipe 70 is connected to one of the interface parts 13, and the other end of the air inlet pipe 70 is connected to the inner liner 1100. One end of the exhaust pipe 80 is connected to the other interface part 13, and the other end of the exhaust pipe 80 is connected to the inner liner 1100.

[0083] It can be understood that the main body 12 and the two interface parts 13 all form a part of the guide channel 11. When the air duct housing 10 is ventilated, the gas passes through one of the interface parts 13, the main body 12 and the other interface part 13 in sequence.

[0084] The evaporator 20 and the condenser 30 are adjacently arranged in the main body 12 , which means that the evaporator 20 and the condenser 30 are arranged side by side in the main body 12 with a small distance therebetween, or the evaporator 20 and the condenser 30 are closely arranged in the main body 12 .

[0085] See also Figure 5 and Figure 8 In some embodiments, two interface portions 13 extend upward from the main body 12 toward the sidewall 1101 of the inner liner 1100. The air inlet pipe 70 and the exhaust pipe 80 are located above the two interface portions 13. The interface portions 13, the air inlet pipe 70, and the exhaust pipe 80 are located on the same side of the inner liner 1100. This avoids the connection between the inner liner 1100 and the air inlet pipe 70 and the exhaust pipe 80, facilitating the assembly of the inner liner 1100 with other components, reducing interference between the inner liner 1100 and surrounding components, and simplifying the structure.

[0086] Specifically, if Figure 8 In the embodiment, the interface portion 13 is formed with a vent 131. The vents 131 of both interface portions 13 face upward, and the lower ends of the intake pipe 70 and the exhaust pipe 80 are connected to the two interface portions 13 through the two vents 131. In this way, the vents 131 allow air to enter the air duct housing 10 from top to bottom through the intake pipe 70, and then flow upward from the air duct housing 10 to the exhaust pipe 80.

[0087] See also Figure 6 and Figure 8 In some embodiments, the main body 12 includes a top surface 120, the interface portion 13 is connected to the edge of the top surface 120, and an accommodating space 1201 is formed between the top surface 120 and the interface portion 13. The accommodating space 1201 accommodates the corner portion where the bottom wall of the inner liner 1100 is connected to the side wall 1101, and the top surface 120 is in contact with the bottom wall of the inner liner 1100.

[0088] In this way, the accommodating space 1201 formed between the top surface 120 and the interface part 13 can accommodate the inner liner 1100, and the interface part 13 can avoid the connection between the inner liner 1100 and the air inlet pipe 70 and the exhaust pipe 80. This is conducive to the assembly of the inner liner 1100 and other components, reduces the interference between the inner liner 1100 and surrounding components, and has a simple structure.

[0089] Specifically, the connection between the interface portion 13 and the top surface 120 can be arc-shaped or bent, and the edge where the top surface 120 connects to the interface portion 13 is higher than the edge where the top surface 120 contacts the bottom wall of the liner 1100. The accommodating space 1201 is the space enclosed 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 liner 1100 contacts the top surface 120, and the side wall 1101 of the liner 1100 contacts the interface portion 13.

[0090] See also Figure 8 and Figure 9 In some embodiments, the main body 12 includes a first shell 121 and a second shell 122 detachably connected to the first shell 121. The two interface portions 13 are integrally formed with the first shell 121. This allows for detachable connection between the first shell 121 and the second shell 122, making it easier to install the evaporator 20 and the condenser 30 within the main body 12, thereby improving the assembly efficiency of the heat pump system 1200. Furthermore, the integral structure of the interface portion 13 with the first shell 121 improves the sealing performance of the connection between the interface portion 13 and the first shell 121, reducing the risk of air leakage in the flow guide channel 11.

[0091] 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 of snaps, screws, etc. The interface portion 13 and the first shell 121 can be formed into an integral structure through an injection molding process.

[0092] See also Figure 6-Figure 9 In certain embodiments, the heat pump system 1200 further includes a fan 40, which is used to generate airflow in the flow guide channel 11. The fan 40 is mounted on the outside of the air duct housing 10. In this manner, the fan 40 can provide power for the flow of gas in the flow guide channel 11. Specifically, the fan 40 can be an axial flow fan 40 or a centrifugal fan 40, and the fan 40 can be mounted on the outside of the second shell 122. When the fan 40 is in operation, a negative pressure is generated in the flow guide channel 11, causing the gas to circulate along the path from the inner liner 1100 to the air inlet pipe 70, the air duct housing 10, the exhaust pipe 80, and finally the inner liner 1100.

[0093] See also Figure 6-Figure 8In some embodiments, there are at least two fans 40, with at least one fan 40 mounted on the air duct housing 10 and at least one fan 40 disposed on the air inlet pipe 70. For example, the fans 40 can be mounted on the air duct housing 10 or the air inlet pipe 70 using screws. In this manner, the at least two fans 40 can increase the flow rate of the gas in the flow channel 11, thereby enhancing the drying effect of the heat pump system 1200.

[0094] Specifically, the number of fans 40 can be two, three, four, etc. At least one fan 40 is mounted on the main body 12 of the air duct housing 10, so that the air duct housing 10 can provide more space for the installation of the fan 40. At least a portion of one fan 40 can be located in the guide 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 air around the condenser 30 to enable gas flow. Alternatively, at least a portion of one fan 40 can be located in the guide channel 11 and downstream of the condenser 30, while at least a portion of another fan 40 can be located in the guide channel 11 and upstream of the evaporator 20.

[0095] At least one fan 40 is disposed on the air inlet duct 70, thereby providing more space for the fan 40. At least a portion of one fan 40 may be located in the air inlet duct 70, upstream of the evaporator 20. When activated, the fan 40 creates positive pressure on the side facing the evaporator 20, thereby driving air around the evaporator 20 and promoting gas flow. Alternatively, at least a portion of one fan 40 may be located at the air inlet end of the air inlet duct 70, while at least a portion of the other fan 40 may be located at the air outlet end of the air inlet duct 70.

[0096] In some embodiments, the fan 40 is only installed on the air duct housing 10. That is, the heat pump system 1200 is provided with at least one fan 40 in the flow guiding channel 11 to provide power for the gas flow in the flow guiding channel 11.

[0097] Since the guide channel 11 between the main body 12 and the interface 13 is non-linear, in order to reduce the resistance to gas flow, the fan 40 adopts a centrifugal fan 40, and the air outlet of the fan 40 faces the interface 13, so that the gas can be discharged directly to the interface 13.

[0098] See also Figure 1 and Figure 6In some embodiments, the heat pump system 1200 further includes a tray 50. The compressor 60 and the air duct housing 10 are both mounted on the tray 50 and located below the inner container 1100. 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 formed into a single unit by the tray 50, facilitating the installation of the heat pump system 1200 as a whole and improving the assembly efficiency of the washing appliance 1000.

[0099] Specifically, the tray 50 can be mounted on the base 1400 of the washing appliance 1000. Because the depth direction X of the inner container 1100 provides more installation space, spacing the compressor 60 and the air duct housing 10 along the depth direction X of the inner container 1100 allows for efficient utilization of the space within the washing appliance 1000 and reduces interference between the compressor 60 and the air duct housing 10 and other components. The depth direction X of the inner container 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0100] See also Figure 2 In some embodiments, the compressor 60 is vertically mounted on the base 1400. As such, the compressor 60 is vertically mounted on the base 1400. Compared to a case where the compressor 60 is horizontally mounted on the base 1400, the compressor 60 occupies less space on the base 1400, thereby improving the space utilization of the base 1400 and making the structure of the washing appliance 1000 more compact.

[0101] See also Figure 4 and Figure 8 In some embodiments, the exhaust duct 80 has a plurality of exhaust ports 81, which are arranged at intervals along the height direction of the inner container 1100. Thus, the plurality of exhaust ports 81 of the exhaust duct 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 of the inner container 1100, thereby achieving a better drying effect.

[0102] The number of the exhaust ports 81 can be two, three, four, etc., and the present application does not limit the specific number of the exhaust ports 81.

[0103] See also Figure 8In some embodiments, the exhaust duct 80 includes a first exhaust section 82 and multiple second exhaust sections 83. Each second exhaust section 83 has an exhaust port 81 formed at its end. The middle portion of each second exhaust section 83 is curved and arched upward. This allows the first exhaust section 82 to direct air into the second exhaust sections 83. The upward curvature of the middle portion of the second exhaust sections 83 prevents condensed water from forming within the exhaust duct 80 from re-entering the inner tank 1100, thereby improving the drying efficiency of the washing machine 1000. Furthermore, the upward curvature of the middle portion of the second exhaust sections 83 prevents water from the inner tank 1100 from directly entering the exhaust duct 80, thereby enhancing the reliability of the heat pump system 1200.

[0104] See also Figure 1 In some embodiments, the air duct component 100 is formed with a guide channel 11, both ends of which are connected to the washing chamber 1104, and the evaporator 20 and the condenser 30 are arranged in the same guide channel 11. Along the guide direction of the guide channel 11, the evaporator 20 is located upstream of the condenser 30, and the heat pump system 1200 is configured to cool and dehumidify the air flowing out of the inner tank 1100 by the evaporator 20 first, and then heat it by the condenser 30 and return it to the inner tank 1100.

[0105] In this way, by setting the evaporator 20 upstream of the condenser 30, the evaporator 20 and the condenser 30 cooperate with each other to first cool and dry the air in the same guide channel 11 and then heat it, so that the washing appliance 1000 can use the heat pump system 1200 to achieve the effect of drying items such as tableware.

[0106] Specifically, the guide channel 11 formed by the air duct component 100 is used to achieve a ventilation effect, allowing air to circulate between the inner tank 1100 of the washing appliance 1000 and the heat pump system 1200 to achieve the effect of drying items such as dishes. The guide channel 11 can be configured into a curved shape or other shape to meet the flow requirements of the airflow. The cross-sectional area of each position of the guide channel 11 can be different. For example, the cross-sectional area of the guide channel 11 at the position used to accommodate the evaporator 20 and the condenser 30 is larger, and the cross-sectional area at other positions is smaller.
