[0030] Please refer to Figures 1-4 , the washing appliance 1000 of the embodiment of the present application includes a base 1400, a main body 1500, and a heat pump drying system 1200. The main body 1500 is disposed on the base 1400 and forms a washing chamber 1104; 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 end of the duct component 100 is connected to the washing chamber 1104. Both the evaporator 20 and the condenser 30 are disposed in the duct component 100. The evaporator 20 is used to cool the gas flowing out of the washing chamber 1104, and the condenser 30 is used to heat the gas flowing into the washing chamber 1104. Among them, one of the evaporator 20 and the condenser 30 is disposed on the base 1400, and the other is disposed on the main body 1500.

[0031] In this way, one of the evaporator 20 and the condenser 30 is disposed on the base 1400, and the other is disposed on the main body 1500, which can make full use of the installation space of the main body 1500, save the installation space of the base 1400, and make the washing appliance 1000 have a high integration degree and a compact structure.

[0032] Specifically, the washing appliance 1000 is mainly used for washing various tableware. The main body 1500 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, and a water cup 1300 placed below the bracket may be disposed in the washing chamber 1104. The water cup 1300 is used to collect and drain the water flow generated during the washing and condensation processes. The washing appliance 1000 is, for example, a dishwasher.

[0033] The base 1400 is located below the main body 1500. The base 1400 is used to carry components such as the main body 1500, the heat pump drying system 1200, and the water cup 1300. A receiving groove 1410 is formed by the top surface of the base 1400 extending downward. Components such as the main body 1500, the heat pump drying system 1200, and the water cup 1300 are arranged in the receiving groove 1410.

[0034] The heat pump drying system 1200 is used to dry the humid and hot air flowing out of the washing chamber 1104 and heat the dried air so that the heated and dried air flows back into the washing chamber 1104 again. In this way, the cycle is realized to achieve the effect of drying objects such as tableware. It should be noted that the dried air mentioned above is relative to the humid and hot air in the washing chamber 1104, and it does not mean that the air does not contain any water vapor at all.

[0035] The evaporator 20 is a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 works, the evaporator 20 can refrigerate, thereby absorbing the heat of the air around the evaporator 20 to reduce 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.

[0036] The condenser 30 is also a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 works, the condenser 30 can heat, thereby releasing heat to the air around the condenser 30 to increase the temperature of the surrounding air, so that after the gas flowing through the condenser 30 enters the washing chamber 1104 of the washing appliance 1000 again, the effect of drying objects such as tableware is achieved.

[0037] It can be that the evaporator 20 is arranged on the base 1400 and the condenser 30 is arranged on the main body 1500, or the condenser 30 is arranged on the base 1400 and the evaporator 20 is arranged on the main body 1500. The condenser 30 and the evaporator 20 can be connected to the compressor 60 through a pipeline 61.

[0038] 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, enabling the refrigerant to circulate in the sealed refrigerant circuit composed of the compressor 60, the condenser 30, the throttling device 90 and the evaporator 20. The cooperation of the four can enable the heat pump drying system 1200 to achieve the effect of drying objects such as tableware. When the heat pump drying system 1200 is in the drying stage, the compressor 60 operates to pump the high-temperature and high-pressure refrigerant to the condenser 30 to heat the air. After the refrigerant exchanges heat with the air, it flows out of the condenser 30, and then passes through the throttling device 90 to be throttled into a low-temperature and low-pressure refrigerant and flows into the evaporator 20 to exchange heat and evaporate with the air, and then returns to the compressor 60 to complete the entire heat pump heating cycle. The dried air is heated by the condenser 30 and then enters the washing chamber 1104 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.

[0039] Please refer to Figure 2 and Figure 4 , in some embodiments, the main body 1500 includes an inner container 1100 and a door body 1600. One of the evaporator 20 and the condenser 30 is disposed on the base 1400, and the other is disposed on the inner container 1100 or the door body 1600.

[0040] In this way, the installation space of the inner container 1100 and the door body 1600 can be fully utilized, the installation space of the base 1400 can be saved, and the washing appliance 1000 has a high integration degree and a compact structure.

[0041] Specifically, the inner container 1100 can form a washing chamber 1104, and the door body 1600 can rotate relative to the base 1400 to open or close the opening of the washing chamber 1104. It can be that the evaporator 20 is disposed on the base 1400 and the condenser 30 is disposed on the side wall 1101 of the inner container 1100 or the door body 1600, or the condenser 30 is disposed on the base 1400 and the evaporator 20 is disposed on the side wall 1101 of the inner container 1100 or the door body 1600. The evaporator 20 or the condenser 30 can be installed below the door body or on the side of the door body 1600 facing the inner container 1100.

[0042] Please refer to Figure 2 and Figure 4 , in some embodiments, the main body 1500 includes an inner container 1100 and a housing 1700 surrounding the inner container 1100. One of the evaporator 20 and the condenser 30 is disposed on the base 1400, and the other is disposed between the inner container 1100 and the housing 1700.

[0043] In this way, the installation space between the inner container 1100 and the outer shell 1700 can be fully utilized, and the installation space of the base 1400 can be saved, so that the washing appliance 1000 has a high integration level and a compact structure.

[0044] Specifically, the outer shell 1700 can cover the inner container 1100, the base 1400, and the heat pump drying system 1200 to protect the inner container 1100, the base 1400, and the heat pump drying system 1200 from being damaged by external impacts. The evaporator 20 can be arranged on the base 1400, and the condenser 30 can be arranged between the inner container 1100 and the outer shell 1700, or the condenser 30 can be arranged on the base 1400, and the evaporator 20 can be arranged between the inner container 1100 and the outer shell 1700. The evaporator 20 or the condenser 30 can be installed on the side wall 1101 of the inner container 1100 facing the outer shell 1700, or can be installed on the side wall of the outer shell 1700 facing the inner container 1100.

[0045] Please refer to Figure 1 , in some embodiments, the air duct component 100 is formed with a diversion channel 11; both ends of the diversion channel 11 are communicated with the washing chamber 1104, the evaporator 20 and the condenser 30 are arranged in the same diversion channel 11, and along the diversion direction of the diversion channel 11, the evaporator 20 is located upstream of the condenser 30. The heat pump drying system 1200 is configured to first cool and dehumidify the air flowing out of the inner container 1100 by the evaporator 20, and then heat it by the condenser 30 and return it to the inner container 1100.

[0046] In this way, by arranging the evaporator 20 upstream of the condenser 30, the evaporator 20 and the condenser 30 cooperate with each other to cool, dry and then heat the air in the same diversion channel 11, so that the washing appliance 1000 can use the heat pump drying system to achieve the effect of drying items such as tableware.

[0047] Specifically, 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 and the heat pump drying system 1200 of the washing appliance 1000 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 of different 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.

[0048] Please refer to Figure 3, in some embodiments, the diversion channel 11 includes an evaporator air duct, the evaporator 20 is disposed in the evaporator air duct 201, and the air duct component 100 is provided with a drain port 15 located below the evaporator 20 and communicating with the evaporator air duct 201. Specifically, the drain port 15 may be located at the bottommost end of the evaporator air duct 201 to facilitate the aggregation of condensed water and discharge the condensed water out of the diversion channel 11 through the drain port 15, reducing the residue of condensed water in the air duct component 100.

[0049] Please refer to Figure 1 and Figure 5 , in some embodiments, the condenser 30 includes a plurality of fins 21, an air flow channel 22 is formed between the plurality of fins 21, and the diversion direction of the air flow channel 22 is the same as the diversion direction of the diversion channel 11.

[0050] In this way, the fins 21 can increase the contact area between the condenser 30 and the air, enabling the heat medium to quickly release heat to the air, continuously introducing the hot air in the environment into the air flow channel 22, and improving the heat exchange efficiency.

[0051] Specifically, the plurality of fins are arranged at intervals in a direction perpendicular to the diversion direction of the diversion channel 11. The shape of the fin 21 can be a square sheet, and the material of the fin 21 can be a metal material with high thermal conductivity, such as copper. It can be understood that the shape of the fin 21 can also be other shapes, which are not specifically limited.

[0052] Please refer to Figure 5 , in some embodiments, the thickness direction of the fin 21 is the same as the horizontal direction, and the height direction h of the fin 21 is perpendicular to the diversion direction of the diversion channel 11 where the condenser 20 is located.

[0053] In this way, the area occupied by the condenser 30 in the diversion channel 11 can be reduced, and further the area occupied by the air duct component 100 on the heat pump drying system 1200 can be reduced, thereby making the structure of the washing appliance 1000 compact.

[0054] Specifically, the height of the fin 21 can be greater than the width of the fin 21. The width direction of the fin 21 is the diversion direction of the diversion 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 h of the fin 21 is the vertical direction perpendicular to the thickness and width directions of the fin 21. The width direction of the fin 21 can be parallel to the width direction of the condenser 30.

[0055] Please refer to Figure 1 , Figure 2 and Figure 6, in some embodiments, the air duct component 100 includes an air duct housing 10, an intake pipe 70, and an exhaust pipe 80. Both the intake pipe 70 and the exhaust pipe 80 are in communication with the air duct housing 10, and both the intake pipe 70 and the exhaust pipe 80 are connected to the inner tank 1100. The evaporator 20 and the condenser 30 are arranged at intervals in the air duct housing 10, and the air duct housing 10, the intake pipe 70, and the exhaust pipe 80 together form a diversion channel 11.

[0056] In this way, the intake pipe 70 can direct the gas in the inner tank 1100 into the air duct housing 10, and the exhaust pipe 80 can introduce the gas that has passed through the evaporator 20 and the condenser 30 in sequence into the inner tank 1100, realizing the circulating flow of the gas between the air duct component 100 and the inner tank 1100. In addition, by arranging the evaporator 20 and the condenser 30 in the air duct housing 10, the air duct housing 10, the evaporator 20, and the condenser 30 can form an integral module, which is convenient for assembling the washing appliance 1000 and is beneficial to reducing the manufacturing cost of the washing appliance 1000.

[0057] Specifically, the air duct housing 10 is used for ventilation. The air duct housing 10 as a whole can be made of materials such as plastics that are easy to mold, so that the air duct housing 10 is easy to manufacture. The air duct housing 10 can be set to a specific external structure according to the installation position of the air duct component 100, so that the air duct component 100 can be more closely matched with the surrounding components. The air duct housing 10 is in communication with the inner tank 1100.

[0058] 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.

[0059] Please refer to Figure 3 , Figure 4 and Figure 6 , in some embodiments, the evaporator 20 is arranged on the side wall 1101 of the inner tank 1100, the condenser 30 is arranged in the air duct housing 10, the air duct housing 10 is arranged on the base 1400, and the evaporator 20 is located above the condenser 30. This can make full use of the side space of the inner tank 1100, save the installation space of the base 1400, and make the washing appliance 1000 have a high integration degree and a compact structure.

[0060] Specifically, the evaporator 20 can be disposed on the left sidewall 1101, the right sidewall 1101 or the rear sidewall 1101 of the inner tank 1100. The condenser 30 can be disposed at one end of the air duct housing 10 close to the intake pipe 70, or can be disposed at one end of the air duct housing 10 close to the exhaust pipe 80. The air duct housing 10 and the evaporator 20 can be disposed on the same side of the inner tank 1100. For example, the evaporator 20 is disposed on the right sidewall 1101 of the inner tank 1100, and the air duct housing 10 is disposed on the right side of the base 1400. The evaporator 20 is located above the condenser 30, and the evaporator 20 can be located above the left of the condenser 30, or the evaporator 20 can be located above the right of the condenser 30.

[0061] Please refer to Figure 1 、 Figure 3 and Figure 4 In some embodiments, the evaporator 20, the intake pipe 70 and the exhaust pipe 80 are all disposed on the inner tank 1100. The evaporator 20 is vertically disposed on the sidewall 1101 of the inner tank 1100, and the height direction h of the evaporator 20 is the same as the flow direction of the diversion channel 11 where the evaporator 20 is located. In this way, 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 of the air flowing through the evaporator 20. In addition, the evaporator 20, the intake pipe 70 and the exhaust pipe 80 are all disposed on the inner tank 1100, so that the evaporator 20, the 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, further improving the reliability of the washing appliance 1000 and reducing the manufacturing cost.

[0062] Specifically, the evaporator 20, the intake pipe 70 and the exhaust pipe 80 can be located on the same sidewall 1101 of the inner tank 1100. For example, the evaporator 20, the intake pipe 70 and the exhaust pipe 80 are located on the right sidewall 1101 of the inner tank 1100, and the condenser 30 is located on the right side of the base 1400.

[0063] Please refer to Figure 3 and Figure 6 In some embodiments, the air duct housing 10 includes a main body portion 12 and two interface portions 13. The two interface portions 13 are both connected to the main body portion 12. The two interface portions 13 are both connected to the same side of the main body portion 12 and are spaced apart. One of the interface portions 13 is connected to the intake pipe 70, and the other interface portion 13 is connected to the exhaust pipe 80.

[0064] In this way, the two interface portions 13 are both connected to the same side of the main body portion 12, so that the air intake and air outlet of the air duct housing are both on the same side, which is beneficial to the assembly of the air duct housing 10 with other components, reduces the interference between the air duct housing 10 and the surrounding components, and has a simple structure.

[0065] Specifically, the volume of the main body portion 12 is greater than that of the interface portion 13, making it easier for the interface portion 13 to be connected to other pipe fittings. The main body portion 12 is generally block-shaped as a whole.

[0066] The interface portion 13 protrudes from the surface of the main body portion 12. The interface portion 13 is similar to a flat tubular shape. The interface portion 13 can be located on one side in the length direction or the width direction of the main body portion 12. The features such as the shape, structure, and size of the two interface portions 13 can be the same, thereby reducing the manufacturing cost of the air duct housing 10.

[0067] Specifically, one end of the intake pipe 70 is connected to one of the interface portions 13, and the other end of the intake pipe 70 is connected to the inner tank 1100. One end of the exhaust pipe 80 is connected to the other interface portion 13, and the other end of the exhaust pipe 80 is connected to the inner tank 1100.

[0068] It can be understood that the main body portion 12 and the two interface portions 13 both form a part of the diversion channel 11. When the air duct housing 10 is ventilated, the gas sequentially passes through one of the interface portions 13, the main body portion 12, and the other interface portion 13.

[0069] Please refer to Figure 1 、 Figure 3 and Figure 6 , in some embodiments, the main body portion 12 includes a top surface 120, the interface portion 13 is connected to the edge of the top surface 120, and a receiving space 1201 is formed between the top surface 120 and the interface portion 13. The receiving space 1201 accommodates the corner portion where the bottom wall of the inner tank 1100 is connected to the side wall 1101, and the top surface 120 is in contact with the bottom wall of the inner tank 1100.

[0070] In this way, the receiving space 1201 formed between the top surface 120 and the interface portion 13 can accommodate the inner tank 1100. The interface portion 13 can avoid the connection of the inner tank 1100 with the intake pipe 70 and the exhaust pipe 80. This is beneficial to the assembly of the inner tank 1100 with other components, reduces the interference between the inner tank 1100 and the surrounding components, and has a simple structure.

[0071] Specifically, the connection between the interface portion 13 and the top surface 120 can be arc-shaped or bent-shaped. The edge where the top surface 120 is connected to the interface portion 13 is higher than the edge where the top surface 120 is in contact with the bottom wall of the inner tank 1100. The receiving space 1201 is a space jointly surrounded by the side of the top surface 120 facing the interface portion 13 and the side of the interface portion 13 facing the top surface 120. The bottom wall of the inner tank 1100 is in contact with the top surface 120, and the side wall of the inner tank 1100 is in contact with the interface portion 13.

[0072] Please refer to Figure 1 、 Figure 3 and Figure 6, in some embodiments, the heat pump drying system 1200 includes a first fan 40 and a second fan 41. The first fan 40 is located between the first through hole 1102 and the evaporator 20, and the second fan 41 is located downstream of the condenser 30. The first fan 40 and the second fan 41 are configured to form an air flow in the diversion channel 11. The air flow flows out of the inner container 1100 and successively passes through the evaporator 20 and the condenser 30 before re-entering the inner container 1100. Thus, the first fan 40 and the second fan 41 can provide power for the gas flow in the diversion channel 11.

[0073] Specifically, the first fan 40 and the second fan 41 can be axial fans or centrifugal fans. When the first fan 40 and the second fan 41 are operating, they form a pressure in the diversion channel 11, causing the gas to circulate along the path of inner container 1100 → diversion channel 11 → inner container 1100.

[0074] The first fan 40 can be installed at the air inlet end of the diversion channel 11 by means of screws. After the first fan 40 is started, a negative pressure can be formed on the side facing the inner container 1100 to extract the gas in the inner container 1100; the second fan 41 can be installed at the air outlet end of the diversion channel 11 by means of screws, forming a positive pressure on the side facing the inner container 1100, thereby driving the gas into the inner container 1100.

[0075] Please refer to Figures 1-3 , in some embodiments, the inner container 1100 is provided with a first through hole 1102 and a second through hole 1103. The intake pipe 70 communicates with the inner container 1100 through the first through hole 1102, and the exhaust pipe 80 communicates with the inner container 1100 through the second through hole 1103.

[0076] Thus, the gas in the inner container 1100 can enter the intake pipe 70 through the first through hole 1102, and the gas in the exhaust pipe 80 can enter the inner container 1100 through the second through hole 1103, realizing the circular flow of gas between the air duct component 100 and the inner container 1100.

[0077] Specifically, the first through hole 1102 and the second through hole 1103 are holes penetrating through the side wall 1101 of the inner container 1100, and the height of the second through hole 1103 can be higher than the height of the first through hole 1102. The first through hole 1102 and the second through hole 1103 can be provided on the same side wall 1101 of the inner container 1100. Exemplarily, the first through hole 1102 and the second through hole 1103 can be simultaneously provided on the left side wall 1101 or the right side wall 1101 of the inner container 1100.

[0078] In some embodiments, the second through hole 1103 can be provided on the top wall of the inner container 1100, and the first through hole 1102 can be provided on the left side wall or the right side wall 1101 of the inner container 1100.

[0079] Please refer to Figure 3 , in some embodiments, the first through hole 1102 and the second through hole 1103 are arranged at intervals along the depth direction X of the inner tank 1100. In this way, it is convenient for the air duct component 100 to be installed on the side wall of the inner tank 1100, providing an arrangement space for the evaporator 20 and the condenser 30.

[0080] Specifically, the first through hole 1102 may be provided at the lower left end of the left side wall 1101 of the inner tank 1100, and the second through hole 1103 may be provided at the upper right end of the left side wall 1101 of the inner tank 1100; alternatively, the first through hole 1102 may be provided at the upper left end of the left side wall 1101 of the inner tank 1100, and the second through hole 1103 may be provided at the lower right end of the left side wall 1101 of the inner tank 1100.

[0081] Along the depth direction X of the inner tank 1100, the first through hole 1102 and the second through hole 1103 may be located between the evaporator 20 and the condenser 30, or the evaporator 20 and the condenser 30 may be located between the first through hole 1102 and the second through hole 1103. The depth direction X of the inner tank 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0082] In summary, please refer to Figures 1-3 , in one embodiment, after the washing appliance 1000 finishes washing and enters the drying mode, the heat pump drying system 1200 starts to work. The fan 40 extracts the humid and hot gas in the inner tank 1100 and enters the diversion channel 11 through the first through hole 1102. After the humid and hot gas passes through the evaporator 20, the evaporator 20 can cool and dehumidify the humid and hot gas. The gas dried by the evaporator 20 is heated after passing through the condenser 30, and the fan 40 drives the heated gas to enter the inner tank 1100 through the second through hole 1103 to dry the tableware. In this way, the cycle is repeated to achieve the effect of drying the tableware.
