[0034] Please refer to Figure 1 and Figure 2, the washing appliance 1000 according to the embodiments of the present application includes a base 1400, a main body 1110, and a heat pump drying system 1200. Among them, the main body 1110 is disposed on the base 1400 and forms a washing chamber 1104. More specifically, the main body 1110 may include an inner container 1100 and a door body (not shown in the figure). The door body may be rotatably connected to the inner container 1100 to open or close the washing chamber 1104. The inner container 1100 forms the washing chamber 1104. The heat pump drying system 1200 is connected to the inner container 1100. The heat pump drying system 1200 is configured 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 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 1-3 , in some embodiments, a first through hole 1102 and a second through hole 1103 that are both communicated with the washing chamber are provided on different sides of the main body 1110. The first through hole 1102 and the second through hole 1103 are spaced apart. The heat pump drying system 1200 includes a duct component 100, a compressor 60, a condenser 30, a throttling device 90, and an evaporator 20 that are connected in sequence to form a closed refrigerant circuit. The duct component 100 forms a diversion channel 11. The duct component 100 extends from the first through hole 1102 along the main body 1110 and the base 1400 to the second through hole 1103. One end of the duct component 100 is docked with the first through hole 1102, and the other end of the duct component 100 is docked with the second through hole 1103. The evaporator 20 is configured to cool the gas flowing out of the washing chamber 1104, and the condenser 30 is configured to heat the gas returning to the washing chamber 1104.

[0037] In this way, the first through hole 1102 and the second through hole 1103 are provided on different sides of the main body 1110, and the duct component 100 extends from the first through hole 1102 along the main body 1110 and the base 1400 to the second through hole 1103. This can reasonably utilize the space of the base, so that the duct component 100 can be more conveniently combined with the main body 1110 and the base 1400. The first through hole 1102 and the second through hole 1103 on different sides are beneficial to improving the gas fluidity in the washing chamber 1104, and further improving the drying efficiency of the heat pump drying system 1200.

[0038] Specifically, as Figures 2-4As shown in the figure, 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. There is a water cup 1300 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 that the contact area between the gas in the diversion channel 11 and the evaporator 20 is increased, 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 that the contact area between the gas in the diversion channel 11 and the condenser 30 is 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, and are connected in sequence to form a closed refrigerant circuit, so that the refrigerant as the refrigerant can 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.

[0044] When the heat pump drying system 1200 is in the drying stage, the compressor 60 operates to pump the refrigerant at high temperature and high pressure 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 refrigerant at low temperature and low pressure 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 container 1100 of the washing appliance 1000 again. The throttling device 90 can be an expansion valve. Further, the throttling device 90 can be an electronic expansion valve.

[0045] The air duct component 100 enables the air in the washing chamber 1104 to form a circulating air flow. For example, the gas in the inner container 1100 enters the air duct component 100 from the air inlet end of the air duct component 100, and after passing through the air duct component 100, it is discharged from the air outlet end of the air duct component 100 to the inner container 1100.

[0046] The diversion channel 11 formed by the air duct component 100 is used to achieve the ventilation effect, so that the gas can circulate between the inner container 1100 of the washing appliance 1000 and the diversion channel 11 to achieve the effect of drying items 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.

[0047] Please refer to Figure 2 , in some embodiments, the main body 1110 includes an inner container 1100 and a door body (not shown in the figure), and the first through hole 1102 and the second through hole 1103 are respectively arranged on different sides of the inner container 1100. Thus, the first through hole 1102 and the second through hole 1103 are arranged on different sides of the inner container 1100, which can facilitate the installation of the air duct component 100 and the inner container 1100.

[0048] Specifically, the first through hole 1102 and the second through hole 1103 can be holes penetrating the surrounding wall of the inner container 1100. The first through hole 1102 and the second through hole 1103 can be arranged on the same surrounding wall of the inner container 1100, or can be arranged on different surrounding walls of the inner container 1100. Exemplarily, the first through hole 1102 and the second through hole 1103 can be simultaneously arranged on the left side wall 1101, the right side wall 1101, the rear side wall 1101 or the top wall of the inner container 1100, or can be respectively arranged on the left side wall 1101, the right side wall 1101, the rear side wall 1101 or the top wall of the inner container 1100. For example, the first through hole 1102 is arranged on the top wall of the inner container 1100, and the second through hole 1103 is arranged on the left side wall 1101 of the inner container 1100.

[0049] In one embodiment, the first through-hole 1102 is provided in the top wall of the inner container 1100, and the second through-hole 1103 is provided in the right side wall 1101 of the inner container 1100. In another embodiment, the first through-hole 1102 and the second through-hole 1103 are respectively provided in the left and right side walls 1101 of the inner container 1100.

[0050] Of course, in some embodiments, one of the first through-hole 1102 and the second through-hole 1103 is provided in the inner container 1100, and the other is provided in the door body.

[0051] In certain embodiments, the height of the first through-hole 1102 is higher than that of the second through-hole 1103. The first through-hole 1102 is used for discharging the gas in the washing chamber 1104, and the second through-hole 1103 is used for returning the heated gas to the washing chamber 1104. 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, in order to achieve a better drying effect, in some embodiments, the height of the first through-hole 1102 is higher than that of the second through-hole 1103, so that the air duct component 100 can more easily extract the humid and hot 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.

[0052] Please refer to Figures 3-6 , in certain embodiments, the air duct component 100 includes an air duct housing 10, an intake pipe 70, and an exhaust pipe 80. 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. Along the flow direction of the diversion channel 11, the evaporator 20 is located upstream of the condenser 30. The heat pump drying system 1200 is configured to first cool and dehumidify the air flowing out of the washing chamber 1104 by the evaporator 20, and then heat it by the condenser 30 and return it to the washing chamber 1104.

[0053] In this way, the evaporator 20 and the condenser 30 cooperate with each other to also cool, dry and then heat the air in the diversion channel 11, so that the washing appliance 1000 can use the heat pump 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.

[0054] Specifically, the air duct housing 10 is installed on the base 1400 of the washing appliance 1000 and is located below the inner container 1100. The base 1400 of the washing appliance 1000 can provide support for the air duct housing 10 and the inner container 1100, so that the installation of the air duct component 100 and the inner container 1100 is stable. The air duct housing 10 can be directly installed on the base 1400, or can be installed on the base 1400 through other media.

[0055] The air duct housing 10 as a whole can be made of materials that are easy to mold, such as plastics, 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 pump drying system 1200, so that the heat pump drying system 1200 can be more compactly fitted 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 the top of the air duct housing 10 is lower than the bottom of the inner tank 1100.

[0056] The intake pipe 70 and the exhaust pipe 80 can at least partially adhere to the inner tank 1100. The intake pipe 70 and the exhaust pipe 80 can both be flat pipes, so as to be conveniently fitted and installed on the side wall 1101 of the inner tank 1100. The intake end of the intake pipe 70 docking with the first through hole 1102 means that the intake end of the intake pipe 70 can be inserted into the first through hole 1102, or can cover the first through hole 1102 on the outer surface of the side wall 1101 of the inner tank 1100. Similarly, the exhaust end of the exhaust pipe 80 docking with the second through hole 1103 means that the exhaust end of the exhaust pipe 80 can be inserted into the second through hole 1103, or can cover the second through hole 1103 on the outer surface of the side wall 1101 of the inner tank 1100.

[0057] The intake pipe 70 and the air duct housing 10 can be of an integrally formed structure or a separable and detachable structure. Similarly, the exhaust pipe 80 and the air duct housing 10 can be of an integrally formed structure or a separable and detachable structure.

[0058] Please refer to Figures 2-4 , in some embodiments, the intake pipe 70 and the exhaust pipe 80 are respectively arranged on opposite sides of the main body 1110, and the air duct component 100 further includes a connecting pipe 110 connecting the intake pipe 70 and the air duct housing 10. The connecting pipe 110 is located in the accommodating space 1410 of the base 1400 and extends along the horizontal direction of the base 1400.

[0059] In this way, the connecting pipe 110 can increase the length of the air duct component 100, so that the gas flowing out of the inner tank 1100 can fully exchange heat with the air duct component 100, which is beneficial to forming condensed water to achieve the purpose of drying.

[0060] In the embodiments of the present application, the accommodating space 1410 of the base 1400 can accommodate some components of the washing appliance 1000, reducing the impact of these components from the outside, thereby improving the service life of the washing appliance 1000. The horizontal direction of the base 1400 is the direction perpendicular to the vertical direction. The horizontal direction of the base 1400 can be the left - right direction, or the front - back direction, or a direction forming a predetermined angle with the left - right direction.

[0061] As mentioned above, the "front" direction is the direction towards which the opening of the washing chamber 1104 faces when the washing appliance 1000 is in normal use, and the "left" direction is the direction on the left side of the washing chamber 1104 when facing the opening of the washing chamber 1104.

[0062] Please refer to Figures 2-4 , in some embodiments, the washing appliance 1000 further includes a water cup 1300 disposed on the base 1400, and the connecting pipe 110 is arranged to bypass the water cup 1300. The connecting pipe 110 bypasses the water cup 1300 from the bottom side or the front side or the rear side of the base 1400. In this way, the connecting pipe 110 is compactly matched with the water cup 1300, rationally utilizing the space of the base 1400, making the structure of the washing appliance 1000 compact and facilitating miniaturization. Additionally, since the water cup 1300 is used to receive the water in the inner container 1100 located above, the connecting pipe 110 bypasses the water cup 1300 from the bottom side or the front side or the rear side of the base 1400, so that the water cup 1300 can be used normally.

[0063] Please refer to Figures 2-4 , in some embodiments, the air duct housing 10 has a first air duct portion 12 and a second air duct portion 13 connected to the first air duct portion 12. The first air duct portion 12 is connected to the connecting pipe 110, or rather, the first air duct portion 12 connects the second air duct and the connecting pipe 110. The first air duct portion 12 has a tendency to converge towards the second air duct portion 13 from the connecting pipe 110, and both the evaporator 20 and the condenser 30 are disposed in the second air duct portion 13.

[0064] In this way, at least part of the width of the first air duct portion 12 gradually decreases towards the evaporator 20, which is beneficial for guiding the gas onto the evaporator 20, thereby improving the effect of the evaporator 20 in forming condensed water from the gas, and further improving the drying effect of the washing appliance 1000.

[0065] Please refer to Figures 2-4 , in some embodiments, the connecting pipe 110 is a bent flat pipe. The connecting pipe 110 includes a bottom surface and side surfaces connected to the bottom surface. The area of the bottom surface of the connecting pipe 110D is larger than the area of the side surfaces. The bottom surface of the connecting pipe 110 is attached to the surface of the base 1400. In this way, the connecting pipe 110 is bent, which can be adapted to the components on the base 1400, improving the compactness of the structure of the washing appliance 1000. Additionally, the area of the bottom surface of the connecting pipe 110 is larger than the area of the side surfaces of the connecting pipe 110, and the bottom surface of the connecting pipe 110 is attached to the surface of the base 1400, which can reduce the height of the connecting pipe 110, reduce the space occupied by the connecting pipe 110, and make the installation of the connecting pipe 110 stable and reliable.

[0066] Please refer to Figures 2-4, in some embodiments, the air duct housing 10 is disposed on the base 1400, the evaporator 20 and the condenser 30 are disposed adjacent to each other in the air duct housing 10, and the evaporator 20 and the condenser 30 are arranged in the left-right direction of the base 1400.

[0067] In this way, the air duct housing 10, the evaporator 20 and the condenser 30 can reasonably utilize the space of the base 1400, making the structure of the washing appliance 1000 more compact. The evaporator 20 and the condenser 30 are disposed adjacent to each other in the air duct housing 10, and the condenser 30 and the evaporator 20 may be located in the same diversion channel 11 and separated by a certain distance. The evaporator 20 is located upstream of the condenser 30, which means that the gas from the inner tank 1100 is first cooled and dehumidified by the evaporator 20 and then heated by the condenser 30.

[0068] Please refer to Figures 2-4 , in some embodiments, the inner tank 1100 is formed with a first through hole 1102 communicating with the intake pipe 70, the washing appliance 1000 further includes a breather 1500, the intake pipe 70 and the breather 1500 are disposed on the same side of the inner tank 1100, and are arranged along the depth direction of the inner tank 1100.

[0069] In some embodiments, the intake pipe 70 and the exhaust pipe 80 are respectively disposed on opposite sides of the inner tank 1100, the exhaust pipe 80, the condenser 30 and the evaporator 20 are located on the same side of the inner tank 1100, the exhaust pipe 80 is disposed on the side wall 1101 of the inner tank 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall of the inner tank 1100 on the same side as the exhaust pipe 80.

[0070] In this way, the space of the washing appliance 1000 can be reasonably utilized, the interference of components such as the evaporator 20, the condenser 30, the intake pipe 70 and the exhaust pipe 80 with the inner tank 1100 can be reduced, the reliability of the washing appliance 1000 is further improved and the manufacturing cost is lower.

[0071] Specifically, the intake pipe 70 and the exhaust pipe 80 may be respectively located on the left side wall 1101 and the right side wall 1101 of the inner tank 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall on the right side of the inner tank 1100.

[0072] It should be noted that the left and right sides of the inner tank 1100 in this application refer to taking the opening of the inner tank 1100 as the front, the surface with the same distance from the left and right side walls 1101 as the reference surface, the left side of the reference surface is the left side of the inner tank 1100, and the right side of the reference surface is the right side of the inner tank 1100.

[0073] Please refer to Figure 1 and Figure 4, in some embodiments, the heat pump drying system 1200 further includes a fan 40. The fan 40 is used to form an air flow in the diversion channel 11, and the fan 40 is installed on the outer side of the air duct housing 10. Thus, the fan 40 can provide power for the gas flow in the diversion channel 11. Specifically, the fan 40 can be an axial flow fan or a centrifugal fan. When the fan 40 operates, a negative pressure is formed in the diversion channel 11, causing the gas to circulate along the path of the inner tank 1100 - intake pipe 70 - air duct housing 10 - exhaust pipe 80 - inner tank 1100.

[0074] In some embodiments, the number of the fans 40 is at least two. At least one fan 40 is installed on the air duct housing 10, and at least one fan 40 is provided on the intake pipe 70. For example, the fan 40 can be installed on the air duct housing 10 or the intake pipe 70 by means of screws. Thus, at least two fans 40 can increase the flow rate of the gas in the diversion channel 11, and further enhance the drying effect of the heat pump drying system 1200.

[0075] Specifically, at least one fan 40 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 fan 40. At least a part of the fan 40 is located in the diversion channel 11 and downstream of the condenser 30. After the fan 40 is started, a negative pressure can be formed on the side facing the condenser 30, so as to suck the air around the condenser 30 to make the gas flow.

[0076] At least one fan 40 can be provided 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 fan 40. At least a part of the fan 40 is located in the intake pipe 70 and upstream of the evaporator 20. After the fan 40 is started, a positive pressure can be formed on the side facing the evaporator 20, so as to drive the air around the evaporator 20 to make the gas flow.

[0077] In some embodiments, the fan 40 includes a first fan 41 and a second fan 42. The first fan 41 is installed on the air duct housing 10 and downstream of the condenser 30, and the second fan 42 is installed at the connection between the connecting pipe 110 and the intake pipe 70. Both the first fan 41 and the second fan 42 are used to form an air flow in the diversion channel 11. In this way, the positions of the first fan 41 and the second fan 42 can be reasonably arranged, the smoothness of the gas flow in the air duct component 100 can be improved, and the structure of the washing appliance 1000 can be made more compact.

[0078] In some embodiments, the fan 40 is only installed on the air duct housing 10. That is, at least one fan 40 is provided on the heat pump drying system 1200 at least on the diversion channel 11 to provide power for the gas flow in the diversion channel 11.

[0079] Please refer to Figures 3-4 , in some embodiments, along the depth direction X of the inner tank 1100, the compressor 60 and the duct housing 10 are spaced apart. Since there is more installation space in the depth direction X of the inner tank 1100, the compressor 60 and the duct housing 10 being spaced apart along the depth direction X of the inner tank 1100 can rationally utilize the space of the washing appliance 1000 and reduce the interference between the compressor 60 and the 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 inwards.

[0080] Please refer to Figure 6 , in some embodiments, the exhaust pipe 80 has a plurality of exhaust ports, and the plurality of exhaust ports are arranged at intervals along the height direction of the inner tank 1100. Thus, the plurality of exhaust ports of the exhaust pipe 80 are arranged at intervals along the height direction of the inner tank 1100, so that the exhaust ports can discharge the dried hot air to different positions in the inner tank 1100, thereby achieving a better drying effect.

[0081] The number of exhaust ports can be two, three, four, etc., and the present application does not limit the specific number of exhaust ports.

[0082] Please refer to Figure 6 , in some embodiments, the exhaust pipe 80 has a first exhaust section 82 and a plurality of second exhaust sections 83. Each end of the second exhaust section 83 forms an exhaust port, and the middle part of the second exhaust section 83 is bent upwards in an arch. Thus, 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 upwards 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 being bent upwards in an arch can also prevent the water in the inner tank 1100 from directly entering the exhaust pipe 80, improving the reliability of the normal operation of the heat pump drying system 1200.

[0083] Please refer to Figure 1 and Figure 7 , in some embodiments, the evaporator 20 and / or the condenser 30 each includes a plurality of fins 21, an air flow channel 22 is formed between the plurality of fins 21, the guiding direction of the air flow channel 22 is the same as the guiding direction of the guiding channel 11, the fins 21 are horizontally arranged, and the plurality of fins 21 are stacked in the vertical direction.

[0084] Thus, the fins 21 can increase the contact area between the evaporator 20 and / or the condenser 30 and the air, so that the refrigerant can quickly absorb and release heat, improving the heat exchange efficiency. In addition, the fins 21 are horizontally arranged, and the plurality of fins 21 are stacked in the vertical direction, so that the height of the evaporator 20 and / or the condenser 30 is smaller, which is beneficial to miniaturizing the washing appliance 1000.

[0085] Specifically, multiple fins 21 may be provided on the evaporator 20, or multiple fins 21 may be provided on the condenser 30, or multiple fins 21 may be provided on both the evaporator 20 and the condenser 30. The multiple fins are arranged at intervals in a direction perpendicular to the flow direction of the diversion channel 11. After being controlled by the throttling device 143, the temperature of the refrigerant is reduced to below the ambient temperature. Therefore, when the humidity of the air flow entering the evaporator 20 is high, the water vapor in the air flow is likely to condense on the evaporator 144 to form condensed water, which flows down through the air flow channel 22.

[0086] The shape of the fin 21 may be a square sheet, and the material of the fin 21 may be a metal material with high thermal conductivity, such as copper. It can be understood that the shape of the fin 21 may also be other shapes, which are not specifically limited.

[0087] In summary, please refer to Figure 1 , in one embodiment, after the washing appliance 1000 finishes washing and enters the drying mode, the fan 40 and the heat pump drying system 1200 start to work. The fan 40 causes the gas to circulate in the inner tank 1100, the intake pipe 70, the air duct housing 10, and the exhaust pipe 80. After the humid and hot gas passes through the evaporator 20, the evaporator 20 can cool the humid and hot air and form condensed water; 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. This cycle is repeated to achieve the effect of drying the tableware.
