  • At least one fan 40 is mounted on the duct housing 10, thereby providing more space for the fan 40 to be installed in the duct housing 10. At least a portion of the fan 40 is located in the flow channel 11 and downstream of the condenser 30. When the fan 40 is started, it can create a negative pressure on the side facing the condenser 30, thereby drawing in air around the condenser 30 to allow gas flow.
  • At least one fan 40 may be installed at the inlet end of the inlet pipe 70, thereby providing more space for the installation of the fan 40 at the inlet end of the inlet pipe 70. At least a portion of the fan 40 is located in the inlet pipe 70 and upstream of the evaporator 20. When the fan 40 is started, it can create positive pressure on the side facing the evaporator 20, thereby driving the air around the evaporator 20 to cause gas flow.
  • the fan 40 includes a first fan 41 and a second fan 42.
  • the first fan 41 is mounted on the duct housing 10 and located downstream of the condenser 30, and the second fan 42 is mounted at the connection between the connecting pipe 110 and the air inlet pipe 70. Both the first fan 41 and the second fan 42 are used to generate airflow in the guide channel 11. This allows for a reasonable arrangement of the positions of the first fan 41 and the second fan 42, improving the smoothness of gas flow in the duct component 100 and making the structure of the washing appliance 1000 more compact.
  • the fan 40 is mounted only on the duct housing 10. That is, the heat pump drying system 1200 has at least one fan 40 on the flow channel 11 to power the gas flow in the flow channel 11.
  • the compressor 60 and the air duct housing 10 are spaced apart along the depth direction X of the inner tank 1100. Since the depth direction X of the inner tank 1100 provides more installation space, the spaced arrangement of the compressor 60 and the air duct housing 10 along the depth direction X of the inner tank 1100 makes efficient use of the space in 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 tank 1100 is the direction in which the opening of the washing chamber 1104 extends inward.
  • the exhaust pipe 80 has multiple exhaust ports, which are spaced apart along the height direction of the inner liner 1100. This arrangement of multiple exhaust ports along the height direction of the inner liner 1100 allows the exhaust ports to discharge dried hot air to different locations within the inner liner 1100, thereby achieving a better drying effect.
  • the number of exhaust ports can be two, three, four, etc., and this application does not limit the specific number of exhaust ports.
  • the exhaust pipe 80 has a first exhaust section 82 and a plurality of second exhaust sections 83, each of which has an exhaust port at its end, and the middle portion of the second exhaust section 83 is curved upwards.
  • gas can be introduced from the first exhaust section 82 into the second exhaust section 83, and the upward curvature of the middle portion of the second exhaust section 83 prevents condensate formed inside the exhaust pipe 80 from re-entering the inner tank 1100, thus improving the drying efficiency of the washing appliance 1000.
  • the upward curvature of the middle portion of the second exhaust section 83 also prevents water in the inner tank 1100 from directly entering the exhaust pipe 80, improving the reliability of the heat pump drying system 1200 during normal operation.
  • the evaporator 20 and/or the condenser 30 both include a plurality of fins 21, and an airflow channel 22 is formed between the plurality of fins 21.
  • the airflow channel 22 is aligned with the airflow channel 11.
  • the fins 21 are arranged horizontally, and the plurality of fins 21 are stacked in the vertical direction.
  • the fins 21 can increase the contact area between the evaporator 20 and/or the condenser 30 and the air, allowing the refrigerant to quickly absorb and release heat, thus improving heat exchange efficiency.
  • the horizontal arrangement of the fins 21 and the stacking of multiple fins 21 in the vertical direction result in a smaller height for the evaporator 20 and/or the condenser 30, which is beneficial for miniaturizing the washing appliance 1000.
  • the evaporator 20 may have multiple fins 21, the condenser 30 may have multiple fins 21, or both the evaporator 20 and the condenser 30 may have multiple fins 21.
  • the multiple fins are arranged at intervals along a direction perpendicular to the flow direction of the guide channel 11. After the refrigerant is controlled by the throttling device 143, its temperature is reduced to below the ambient temperature. Therefore, when the humidity of the airflow entering the evaporator 20 is high, the water vapor in the airflow easily condenses on the evaporator 144 to form condensate, which then flows down through the airflow channel 22.
  • the fin 21 can be square-shaped, and the material of the fin 21 can be a metal with high thermal conductivity, such as copper. It is understood that the shape of the fin 21 can also be other shapes, and there are no specific restrictions.
  • the fan 40 and the heat pump drying system 1200 start working.
  • the fan 40 causes the gas to circulate in the inner tank 1100, the air inlet pipe 70, the air duct housing 10, and the exhaust pipe 80.
  • the evaporator 20 can cool the hot and humid air and form condensate.
  • the air passes through the condenser 30 and is heated, and then enters the inner tank 1100 again to dry the tableware. This cycle is repeated to achieve the effect of drying the tableware.
  • references to terms such as “one embodiment,” “some embodiments,” “illustrative embodiment,” “example,” “specific example,” or “some examples,” etc. indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this application.
