[0034] See also Figure 1 The present application provides a washing appliance 1000, comprising an inner tank 1100, a heat pump drying system 1200 and a turbulent air duct 1500. The inner tank 1100 is provided with a washing chamber 1101. The heat pump drying system 1200 comprises an air duct component 100, a compressor 60, a condenser 30, a throttling device 90 and an evaporator 20 connected in sequence to form a closed refrigerant circuit. A plurality of first vents 101 are formed at the end of the air duct component 100, and the plurality of first vents 101 are all connected to the washing chamber 1101. The evaporator 20 and the condenser 30 are both arranged in the air duct component 100. 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. A plurality of second vents 1501 are formed at both ends of the turbulent air duct 1500, and the plurality of second vents 1501 are all connected to the washing chamber 1101.

[0035] Thus, the second vent 1501 allows air to enter the turbulent air duct 1500 from the washing chamber 1101, or to enter the washing chamber 1101 from the turbulent air duct 1500. The turbulent air duct 1500 can disturb the airflow in the inner tank 1100, increase the uniformity of temperature distribution, reduce condensation, and thus improve the drying effect of the washing appliance 1000.

[0036] Specifically, the washing appliance 1000 is mainly used for washing various dishes, wherein the inner tank 1100 can serve as the main structure of the washing appliance 1000, and the washing chamber 1101 can serve as the actual place for washing items. The washing appliance 1000 is, for example, a dishwasher.

[0037] Heat pump drying system 1200 is used to dry the hot and humid air flowing out of inner container 1100 and heat the dried air, allowing the heated, dry air to flow back into inner container 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 container 1100, and does not mean that the air is completely free of moisture.

[0038] The turbulent air duct 1500 allows air to circulate between the inner container 1100 of the washing appliance 1000 and the turbulent air duct 1500, thereby disturbing the airflow within the inner container 1100. The turbulent air duct 1500 can be configured in a curved shape or other shape to meet airflow requirements. The cross-sectional area of the turbulent air duct 1500 can vary at different locations. For example, the cross-sectional area of the turbulent air duct 1500 where the second fan 41 is located can be larger, while the cross-sectional area of other locations can be smaller.

[0039] 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 generates cooling energy, 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.

[0040] 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.

[0041] 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 generates heat, thereby absorbing heat from the surrounding air 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.

[0042] The condenser 30 is generally flat and can be placed vertically, or in other words, the thickness of the condenser 30 is arranged generally horizontally. 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 increased, which is conducive to improving the heating effect of the air flowing through the condenser 30.

[0043] The compressor 60, condenser 30, throttling device 90, and evaporator 20 are the main components of the heat pump drying system 1200 of the washing machine 1000. They are connected in sequence to form a closed refrigerant circuit, allowing the refrigerant, serving as a refrigerant, to circulate within 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 drying system 1200 to effectively dry items such as dishes. During the heating phase of the heat pump drying system 1200, 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. It is then throttled by the throttling device 90, becoming a low-temperature, low-pressure refrigerant that flows into the evaporator 20, where it exchanges heat with the air and evaporates. The refrigerant then returns to the compressor 60 to complete the 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.

[0044] The number of the first vents 101 and the second vents 1501 can be two, three, four, etc. The two ends of the air duct component 100 can each be formed with at least one first vent 101. Similarly, the two ends of the spoiler air duct 1500 can each be formed with at least one second vent 1501. The shapes and sizes of the first vents 101 and the second vents 1501 can be the same or different. The shapes of the first vents 101 and the second vents 1501 can be regular shapes such as rectangles, circles, and ovals, or irregular shapes. In one embodiment, to facilitate forming a connection port on the inner liner 1100 that matches the first vents 101 and the second vents 1501, the shapes and sizes of the first vents 101 and the second vents 1501 can be the same.

[0045] In some embodiments, both ends of the spoiler duct 1500 are connected to the same side wall of the inner liner 1100 , and / or both ends of the duct component 100 are connected to the same side wall of the inner liner 1100 .

[0046] In this way, the multiple second vents 1501 of the spoiler duct 1500 are all located on the same side of the inner liner 1100, and the multiple first vents 101 of the duct component 100 are all located on the same side of the inner liner 1100. 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 simplifies the structure.

[0047] Specifically, both ends of the spoiler duct 1500 can be connected to the left wall, right wall or rear wall of the inner tank 1100, thereby reducing interference between the spoiler duct 1500 and other components of the washing appliance 1000 and improving the reliability of the washing appliance 1000.

[0048] Both ends of the air duct component 100 can be connected to the left side wall, right side wall or rear side wall of the inner tank 1100, thereby reducing interference between the air duct component 100 and other components of the washing appliance 1000 and improving the reliability of the washing appliance 1000.

[0049] The two ends of the spoiler duct 1500 may be connected to the same side wall of the inner liner 1100, and the two ends of the duct component 100 may be connected to different side walls of the inner liner 1100. Alternatively, the two ends of the spoiler duct 1500 may be connected to different side walls of the inner liner 1100, and the two ends of the duct component 100 may be connected to the same side wall of the inner liner 1100. Alternatively, the two ends of the spoiler duct 1500 may be connected to the same side wall of the inner liner 1100, and the two ends of the duct component 100 may be connected to the same side wall of the inner liner 1100.

[0050] The two ends of the spoiler duct 1500 can be connected to the same height position of the same side wall of the inner liner 1100, or can be connected to different height positions of the same side wall of the inner liner 1100. For example, one end of the spoiler duct 1500 is connected to the upper end of the left side wall of the inner liner 1100, and the other end is connected to the lower end of the left side wall of the inner liner 1100; for another example, one end of the spoiler duct 1500 is connected to the left end of the rear side wall of the inner liner 1100, and the other end is connected to the right end of the rear side wall of the inner liner 1100; for another example, one end of the spoiler duct 1500 is connected to the upper left end of the rear side wall of the inner liner 1100, and the other end is connected to the lower right end of the rear side wall of the inner liner 1100.

[0051] In one embodiment, the two ends of the spoiler duct 1500 can be connected to different side walls of the inner liner 1100. For example, one end of the spoiler duct 1500 is connected to the left side wall of the inner liner 1100, and the other end is connected to the rear side wall of the inner liner 1100.

[0052] The two ends of the air duct component 100 can be connected to the same height position of the same side wall of the inner liner 1100, or can be connected to different height positions of the same side wall of the inner liner 1100. For example, one end of the air duct component 100 is connected to the upper end of the left side wall of the inner liner 1100, and the other end is connected to the lower end of the left side wall of the inner liner 1100; for another example, one end of the air duct component 100 is connected to the left end of the rear side wall of the inner liner 1100, and the other end is connected to the right end of the rear side wall of the inner liner 1100; for another example, one end of the air duct component 100 is connected to the upper left end of the rear side wall of the inner liner 1100, and the other end is connected to the lower right end of the rear side wall of the inner liner 1100.

[0053] In one embodiment, the two ends of the duct component 100 can be connected to different side walls of the inner container 1100. For example, one end of the duct component 100 is connected to the left side wall of the inner container 1100, and the other end is connected to the rear side wall of the inner container 1100.

[0054] The two ends of the spoiler duct 1500 and the two ends of the duct component 100 can be connected to the same side wall of the inner liner 1100 , or can be connected to different side walls of the inner liner 1100 .

[0055] See also Figure 1 In some embodiments, the liner 1100 includes a first side 1102 and a second side 1103 opposite to each other, the air duct component 100 is disposed on the first side 1102 , and the spoiler air duct 1500 is disposed on the second side 1103 .

[0056] In this way, the air duct component 100 and the spoiler duct 1500 are arranged on opposite sides of the inner liner 1100, reducing the interference between the air duct component 100 and the spoiler duct 1500, and at the same time simplifying the design and length of the air duct component 100 and the spoiler duct 1500, thereby improving the flow efficiency and flow rate of the gas.

[0057] Specifically, the first side 1102 may be the left side, the second side 1103 may be the right side, the air duct component 100 may be disposed on the left side, and the spoiler duct 1500 may be disposed on the right side. For example, both ends of the air duct component 100 may be connected to the left side wall of the inner liner 1100, and both ends of the spoiler duct 1500 may be connected to the right side wall of the inner liner 1100.

[0058] In one embodiment, the air duct component 100 and the spoiler duct 1500 can be arranged on two adjacent sides of the inner liner 1100. For example, the two ends of the air duct component 100 are connected to the left side wall of the inner liner 1100, and the two ends of the spoiler duct 1500 are connected to the rear side wall of the inner liner 1100.

[0059] See also Figure 1 In some embodiments, the air duct component 100 is formed with a guide channel 11, both ends of the guide channel 11 are connected to the washing chamber 1101, 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 drying 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.

[0060] 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 drying system 1200 to achieve the effect of drying items such as tableware.

[0061] 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 drying 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.

[0062] See also Figure 1-Figure 4 In some embodiments, the evaporator 20 and / or the condenser 30 includes a plurality of fins 21 , and an air flow channel 22 is formed between the plurality of fins 21 . The guide direction of the air flow channel 22 is consistent with the guide direction of the guide channel 11 .

[0063] 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, thereby improving the heat exchange efficiency.

[0064] Specifically, multiple fins 21 may be provided on the evaporator 20, the condenser 30, or both the evaporator 20 and the condenser 30. The multiple fins 21 are spaced apart and arranged perpendicular to the flow direction of the flow channel 11. The refrigerant is controlled by the throttling device 143 to reduce its temperature to below the ambient temperature. Therefore, when the airflow entering the evaporator 20 has a high humidity, water vapor in the airflow easily condenses on the evaporator 144 to form condensed water, which then flows down through the airflow channel 22.

[0065] The fins 21 may be in the shape of a square sheet, and the material of the fins 21 may be a metal material with high thermal conductivity, such as copper. It is understood that the fins 21 may also be in other shapes, which are not specifically limited.

[0066] 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 .

[0067] In this way, the width of the fin 21 is smaller, which can reduce the area occupied by the evaporator 20 and / or condenser 30 in the guide channel 11, and further reduce the area occupied by the air duct component 100 on the heat pump drying system 1200, thereby making the washing appliance 1000 compact.

[0068] Specifically, the width direction of the fin 21 is the guide direction of the guide 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.

[0069] See also Figure 1 、 Figure 3 and Figure 4 In some embodiments, the air duct component 100 includes an air duct housing 10, an air inlet pipe 70 and an exhaust pipe 80. The air inlet pipe 70 and the exhaust pipe 80 are both connected to the air duct housing 10. The evaporator 20 and the condenser 30 are arranged at intervals in the air duct housing 10. The air duct housing 10, the air inlet pipe 70 and the exhaust pipe 80 together form a guide channel 11.

[0070] In this way, the air inlet pipe 70 can direct the gas in the inner liner 1100 into the air duct housing 10, and the exhaust pipe 80 can direct the gas after passing through the evaporator 20 and condenser 30 into the inner liner 1100, thereby achieving a gas circulation between the air duct component 100 and the inner liner 1100. In addition, the evaporator 20 and condenser 30 are arranged in the air duct housing 10, so that the air duct housing 10, evaporator 20, and condenser 30 can form an integrated module, which is convenient for assembly to form the washing machine 1000 and helps reduce the manufacturing cost of the washing machine 1000.

[0071] Specifically, 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 drying 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.

[0072] 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.

[0073] In the embodiment of the present application, the modular design of the air duct component 100 can reduce the number of parts that need to be assembled in the washing appliance 1000 during assembly, improve the assembly effect of the washing appliance 1000, and thus reduce the manufacturing cost of the washing appliance 1000.

[0074] 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.

[0075] Since the hot and humid air in the inner liner 1100 flows upward, and objects such as tableware are located below the top of the inner liner 1100, in order to achieve just the right drying effect, in some embodiments, the end where the air inlet pipe 70 is connected to the inner liner 1100 is higher than the end where the exhaust pipe 80 is connected to the inner liner 1100, so that the air inlet pipe 70 can more easily extract the hot and humid air in the inner liner 1100, and the exhaust pipe 80 can discharge the dry hot air to a position below the top of the inner liner 1100, thereby better drying objects such as tableware.

[0076] See also Figure 1 and Figure 4 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.

[0077] Specifically, the air inlet pipe 70 and the exhaust pipe 80 may be located on the same side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 may be located below the bottom wall of the inner container 1100 on the same side as the air inlet pipe 70 and the exhaust pipe 80. For example, the air inlet 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.

[0078] In one embodiment, the evaporator 20, the air inlet pipe 70, the condenser 30, and the exhaust pipe 80 can be located on different sides of the inner liner 1100. For example, the evaporator 20 and the air inlet pipe 70 are located on the left side of the inner liner 1100, and the condenser 30 and the exhaust pipe 80 are located on the right side of the inner liner 1100.

[0079] 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.

[0080] In some embodiments, the air inlet pipe 70 and the exhaust pipe 80 can both be connected to the side walls of the inner tank 1100. For example, the air inlet pipe 70 and the exhaust pipe 80 can both be connected to the left side wall, right side wall or rear side wall of the inner tank 1100, thereby reducing the interference between the air inlet pipe 70 and the exhaust pipe 80 and other components of the washing appliance 1000 and improving the reliability of the washing appliance 1000.

[0081] In some embodiments, the air inlet pipe 70 may be connected to the top wall of the inner liner 1100 , while the air outlet pipe 80 is connected to the side wall of the inner liner 1100 .

[0082] Combine Figure 1 and Figure 3 The connection between the air inlet pipe 70 and the inner liner 1100 forms an air inlet 71, and the connection between the exhaust pipe 80 and the inner liner 1100 forms an air outlet 81. One end of the guide channel 11 is connected to the washing chamber 1101 through the air inlet 71. The hot and humid air in the washing chamber 1101 flows into the guide channel 11 through the air inlet 71. The other end of the guide channel 11 is connected to the washing chamber 1101 through the air outlet 81. The dried and heated air in the guide channel 11 flows into the washing chamber 1101 through the air outlet 81. The first ventilation port 101 includes the air inlet 71 and the air outlet 81, each of which is provided with a baffle 1400.

[0083] See also Figure 5 In some embodiments, the exhaust duct 80 has a plurality of exhaust ports 81, which are spaced apart along the height direction of the inner container 1100. Thus, the plurality of exhaust ports 81 of the exhaust duct 80 are spaced apart 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.

[0084] The number of the exhaust ports 81 may be two, three, four, etc., and the present application does not limit the specific number of the exhaust ports 81 .

[0085] See also Figure 4 and Figure 5 In 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 directly entering the inner tank 1100 into the exhaust duct 80, thereby enhancing the reliability of the heat pump drying system 1200.

[0086] See also Figure 3 、 Figure 5 and Figure 6 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 used for air intake and the other is used for air outlet, and the evaporator 20 and the condenser 30 are adjacently arranged in the main body 12.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] In some embodiments, one end of the air inlet pipe 70 is connected to one of the interface portions 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 portion 13, and the other end of the exhaust pipe 80 is connected to the inner liner 1100. Both the air inlet pipe 70 and the exhaust pipe 80 can be flat tubes to facilitate installation on the outer wall of the inner liner 1100.

[0092] 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 .

[0093] See also Figure 5 and Figure 6 In some embodiments, the interface portion 13 is formed with a vent 131, and the vents 131 of the two interface portions 13 are oriented in the same direction. Thus, the vent 131 allows air to enter the air duct housing 10 or to flow out of the air duct housing 10. The same orientation of the two vents 131 allows other pipes connected to the interface portion 13 to extend in the same direction, facilitating assembly of the air duct component 100.

[0094] like Figure 6 In the embodiment, the vents 131 of the two connecting pipes are all facing upward. In this way, the gas enters the air duct housing 10 from top to bottom, and then flows out from the air duct housing 10 upward.

[0095] See also Figure 5 and Figure 6 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 condenser 30 within the main body 12, thereby improving the assembly efficiency of the air duct component 100. Furthermore, the integral structure of the interface portion 13 with the first shell 121 improves the sealing performance of the connection between the connecting pipe and the first shell 121, reducing the risk of air leakage in the guide channel 11.

[0096] 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.

[0097] See also Figure 6 and Figure 7 In 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.

[0098] 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.

[0099] 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.

[0100] See also Figure 6 and Figure 7In 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.

[0101] 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 .

[0102] See also Figure 3-Figure 5 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 condenser 30 and the evaporator 20 are connected to the compressor 60 via a pipe 61. Thus, the compressor 60 and the air duct housing 10 are integrally formed by the tray 50, facilitating the integral installation of the air duct component 100 and improving the assembly efficiency of the washing appliance 1000.

[0103] See also Figure 1 and Figure 4 In some embodiments, the heat pump drying system 1200 further includes a first fan 40 and a second fan 41. The first fan 40 is used to form a first airflow in the air duct component 100. The first airflow flows out through the inner tank 1100 and passes through the air inlet pipe 70, the evaporator 20 and the condenser 30 in sequence, and then enters the inner tank 1100 again from the exhaust pipe 80. The second fan 41 is used to form a second airflow in the turbulent air duct 1500. The second airflow flows out through the inner tank 1100 and passes through the turbulent air duct 1500 and then flows into the inner tank 1100 again.

[0104] Thus, the first fan 40 can provide power for the air flow in the air duct component 100, and the second fan 41 can provide power for the air flow in the turbulent air duct 1500. Specifically, the first fan 40 and the second fan 41 can be axial fans or centrifugal fans.

[0105] In some embodiments, there are two first fans 40, one of which is mounted on the air duct housing 10 and the other is located at the air inlet end of the air inlet pipe 70. Thus, the two first fans 40 can increase the flow rate of the gas in the guide channel 11, thereby enhancing the drying effect of the heat pump drying system 1200.

[0106] Specifically, one of the first fans 40 can be mounted on the air duct housing 10 by means of screws, forming a whole with the air duct housing 10 , so that the air duct component 100 is easy to assemble.

[0107] Furthermore, the first fan 40 is mounted on the main body 12 of the air duct housing 10, thereby providing more space within the air duct housing 10 for mounting the first fan 40. At least a portion of the first fan 40 is located within the flow guide channel 11, downstream of the condenser 30. When the first fan 40 is activated, a negative pressure is created on the side facing the condenser 30, thereby drawing air around the condenser 30 and causing gas flow.

[0108] Since the guide channel 11 between the main body 12 and the interface portion 13 is non-linear, in order to reduce the resistance to gas flow, the first fan 40 adopts a centrifugal fan 40, and the air outlet of the first fan 40 faces the interface portion 13, so that the gas can be discharged directly to the interface portion 13.

[0109] Another first fan 40 is disposed at the air inlet end of the air inlet duct 70, that is, at the end of the air inlet duct 70 where the air inlet 71 is formed, or at a section of the duct near the air inlet 71. This allows the air inlet end of the air inlet duct 70 to provide more space for the installation of the first fan 40. At least a portion of the first fan 40 is located in the air inlet duct 70, upstream of the evaporator 20. When the first fan 40 is activated, it creates positive pressure on the side facing the evaporator 20, thereby driving the air around the evaporator 20 and causing gas to flow.

[0110] In some embodiments, the first fan 40 is only installed on the air duct housing 10. That is, the heat pump drying system 1200 is provided with at least one first fan 40 in the guide channel 11 to provide power for the gas flow in the guide channel 11.

[0111] See also Figure 1 In some embodiments, the washing appliance 1000 includes a baffle 1400, which is movably disposed at the first vent 101 and / or the second vent 1501, and the baffle 1400 is used to separate or connect the washing chamber 1101 with the air duct component 100 and / or the spoiler air duct 1500.

[0112] In this way, by arranging a movable baffle 1400 at the first vent 101 and / or the second vent 1501, the baffle 1400 separates the washing chamber 1101 from the air duct component 100 and / or the spoiler duct 1500 during the washing process, and connects the washing chamber 1101 with the air duct component 100 and / or the spoiler duct 1500 when the heat pump drying system 1200 performs dehumidification, thereby reducing the entry of oil, detergent, etc. in the washing chamber 1101 into the air duct component 100 and / or the spoiler duct 1500, avoiding contamination of the utensils in the air duct component 100 and / or the spoiler duct 1500, and improving the reliability of the heat pump drying system 1200.

[0113] Specifically, the baffle 1400 can be movably disposed at the first vent 101, or at the second vent 1501, or can be movably disposed at both the first vent 101 and the second vent 1501. During the washing process, water, detergent, etc. can be sprayed and injected into the washing chamber 1101 to clean the dishes. Grease, detergent, etc. on the dishes are easily splashed into the washing chamber 1101 by the water flow and the operation of the cleaning device. During the washing process, the baffle 1400 maintains coverage over the first vent 101 and / or the second vent 1501, effectively preventing contaminants such as grease, detergent, etc. from entering the air duct component 100 from the first vent 101 and / or from entering the turbulent air duct 1500 from the second vent 1501.

[0114] After cleaning is complete, the baffle 1400 moves relative to the air duct component 100 to open the first vent 101 and / or the second vent 1501, placing the washing chamber 1101 in communication with the interior of the air duct component 100 and / or the spoiler duct 1500. The heat pump drying system 1200 operates to dehumidify and heat the air within the washing chamber 1101 and the air duct component 100. After the dishes are dried, or before the next washing cycle begins, the baffle 1400 can again move relative to the air duct component 100 to cover the first vent 101 and / or the second vent 1501, isolating the washing chamber 1101 from the air duct component 100 and / or the spoiler duct 1500.

[0115] Baffle 1400 may be a thin plate or sheet structure, and the area of baffle 1400 is greater than or equal to the cross-sectional area of first vent 101 and second vent 1501 to ensure that baffle 1400 can fully cover first vent 101 and second vent 1501. The cross-sectional area of first vent 101 and second vent 1501 refers to the cross-sectional area formed perpendicular to the direction of air flow through first vent 101 and / or second vent 1501. The present application does not limit the shape of the baffle 1400. The shape of the baffle 1400 can match the cross-sectional shape of the first vent 101 and the second vent 1501. For example, the cross-sectional shapes of the baffle 1400, the first vent 101, and the second vent 1501 are all elliptical, and the baffle 1400 is concentric with the cross-sectional shape of the first vent 101 or the second vent 1501. The major axis of the baffle 1400 is greater than the minor axis of the cross-sectional shape of the first vent 101 and the second vent 1501, and the minor axis of the baffle 1400 is greater than the minor axis of the cross-sectional shape of the first vent 101 and the second vent 1501. For another example, the shape of the baffle 1400 is different from that of the first vent 101 and the second vent 1501, and the dimensions of the baffle 1400 in all directions are greater than the dimensions of the cross-sectional shape of the first vent 101 and the second vent 1501 in the same direction.

[0116] Furthermore, by closely cooperating with the baffle 1400 and the channel wall at the first vent 101 and / or the second vent 1501, the sealing effect between the washing chamber 1101 and the air duct component 100 and the inside of the turbulent air duct 1500 can be improved during the washing process, thereby reducing the risk of contamination.

[0117] See also Figure 1 In some embodiments, the washing appliance 1000 further includes a driving device 1410 connected to the baffle 1400, and the driving device 1410 is used to drive the baffle 1400 to rotate. In this way, the driving device 1410 is connected to the baffle 1400 to provide driving force for the baffle 1400, further ensuring the reliability of the movable structure of the baffle 1400.

[0118] Specifically, the drive device 1410 is a structure capable of providing a driving force to rotate the baffle 1400. The drive methods of the drive device 1410 include, but are not limited to, motor drive, hydraulic drive, air pump drive, thermal drive, etc. The drive device 1410 may include one or more transmission structures selected from the group consisting of a rotating shaft, a rotating rod, a gear, a chain, a cam, and a bearing. The transmission structure is connected to the baffle 1400 to drive the baffle 1400 to rotate. For example, the drive device 1410 includes a rotating shaft 1411 connected to a side edge of the baffle 1400. The rotating shaft 1411 is disposed at the first vent 101 and / or the second vent 1501. The rotating shaft 1411 is connected to the baffle 1400 and serves as the rotation center of the baffle 1400. The rotating shaft 1411 is configured to rotate along the direction of airflow entering and exiting the first vent 101 and / or the second vent 1501.

[0119] In some embodiments, the driving device 1410 controls the rotation angle of the baffle 1400 by providing a braking force to the baffle 1400 .

[0120] In other embodiments, a limiting device, such as a protrusion, a slot, etc., may be provided in the air duct component 100 to limit the rotation angle of the baffle 1400 .

[0121] In summary, please refer to Figure 1 and Figure 4 In one embodiment, after the washing appliance 1000 completes washing and enters the drying mode, the first fan 40, the second fan 41 and the heat pump drying system 1200 start working, the baffle 1400 rotates relative to the air duct component 100 and opens the first vent 101, the washing chamber 1101 is connected to the air duct component 100, and the first fan 40 allows the gas to circulate in the inner tank 1100, the air inlet pipe 70, the air duct housing 10 and the exhaust pipe 80. After the hot and humid gas passes through the evaporator 20, the evaporator 20 can cool the hot and humid air and form condensed water, which drips into the water receiving tray 14; the air dried by the evaporator 20 passes through the condenser 30 and is heated, and then enters the inner tank 1100 again to dry the dishes. This cycle achieves the effect of drying the dishes. At the same time, the baffle 1400 rotates relative to the turbulent air duct 1500 and opens the second vent 1501, the washing chamber 1101 is connected to the turbulent air duct 1500, and the second fan 41 causes the gas to circulate in the inner tank 1100 and the turbulent air duct 1500, disturbing the airflow in the inner tank 1100.
