[0029] Please refer to Figures 1 - 3 , the washing appliance 1000 of the embodiment of the present application includes an inner container 1100 and a heat pump drying system 120, the inner container 1100 is provided with a washing chamber 1104; the heat pump drying system 120 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 inner container 1100, and the condenser 30 is used to heat the gas flowing into the inner container 1100. Among them, the evaporator 20 and the condenser 30 are disposed on the same side wall 1101 of the inner container 1100 along the depth direction X of the inner container 1100.

[0030] Thus, since there is more installation space in the depth direction X of the inner container 1100, the evaporator 20 and the condenser 30 are arranged on the same side wall 1101 of the inner container 1100 along the depth direction X of the inner container 1100. This enables the evaporator 20 and the condenser 30 to be located on the same side of the inner container 1100, making full use of the side space of the inner container 1100, reducing the interference between the evaporator 20 and the condenser 30 and other components, and resulting in a high integration degree and a compact structure of the washing appliance 1000.

[0031] Specifically, the washing appliance 1000 is mainly used for washing various types of tableware. Among them, the inner container 1100 can serve as the main structure of the washing appliance 1000. The inner container 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 the tableware, and a water cup 1300 placed below the bracket can be provided 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.

[0032] The heat pump drying system 1200 is used 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 back into the inner container 1100 again. In this way, through circulation, the effect of drying objects such as tableware is achieved. 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 contains no water vapor at all.

[0033] 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.

[0034] 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 raise the temperature of the surrounding air, so that after the gas flowing through the condenser 30 enters the inner container 1100 of the washing appliance 1000 again, the effect of drying objects such as tableware is achieved.

[0035] The condenser 30 and the evaporator 20 can be connected to the compressor 60 through a pipeline 61. 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 dishwashing appliance 1000. They are connected in sequence to form a closed refrigerant circuit, enabling the refrigerant to circulate in the sealed refrigerant circuit formed by the compressor 60, the condenser 30, the throttling device 90, and the evaporator 20. The cooperation of these four components can enable the heat pump drying system 1200 to achieve the effect of drying objects such as dishes. 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 inner container 1100 of the dishwashing appliance 1000 again. The throttling device 90 can be an expansion valve. Further, the throttling device 90 can be an electronic expansion valve.

[0036] Both ends of the air duct component 100 can be connected to the same side wall 1101 of the inner container 1100, or can be connected to the top wall and the side wall 1101 of the inner container 1100. For example, both ends of the air duct component 100 are connected to the right side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 are arranged along the depth direction X of the inner container 1100 on the right side wall 1101; for another example, one end of the air duct component 100 is connected to the top wall of the inner container 1100, and the other end is connected to the left side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 are arranged along the depth direction X of the inner container 1100 on the left side wall 1101. The depth direction X of the inner container 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0037] 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 connected to the washing chamber 1104. The evaporator 20 and the condenser 30 are arranged adjacent to each other in the diversion channel 11. 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.

[0038] 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 and then heat the air in the same diversion channel 11, so that the dishwashing appliance 1000 can utilize the heat pump drying system to achieve the effect of drying objects such as dishes.

[0039] Specifically, the diversion channel 11 formed by the air duct component 100 is used to achieve the ventilation effect, enabling the gas to circulate between the inner tank 1100 of the washing appliance 1000 and the heat pump drying system 1200, so as to achieve the effect of drying items such as dishes. 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 where the diversion channel 11 is used to accommodate the evaporator 20 and the condenser 30 is larger, and the cross-sectional areas of other positions are smaller.

[0040] The evaporator 20 and the condenser 30 are generally flat. Please refer to Figure 2 , in some embodiments, the evaporator 20 is vertically arranged on the side wall 1101 of the inner tank 1100, and the height direction of the evaporator 20 is the same as the diversion direction of the diversion channel 11 where the evaporator 20 is located, and / or the condenser 30 is vertically arranged on the side wall 1101 of the inner tank 1100, and the height direction of the condenser 30 is the same as the diversion direction of the diversion channel 11 where the condenser 30 is located.

[0041] 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, and the contact area between the gas in the diversion channel 11 and the condenser 30 is increased, which is beneficial to improving the heating effect of the air flowing through the condenser 30.

[0042] Specifically, it can be that the evaporator 20 is vertically arranged on the side wall 1101 of the inner tank 1100, and the height direction of the evaporator 20 is the same as the diversion direction of the diversion channel 11 where the evaporator 20 is located, or it can be that the condenser 30 is vertically arranged on the side wall 1101 of the inner tank 1100, and the height direction of the condenser 30 is the same as the diversion direction of the diversion channel 11 where the condenser 30 is located, or it can also be that both the evaporator 20 and the condenser 30 are vertically arranged on the side wall 1101 of the inner tank 1100, the height direction of the evaporator 20 is the same as the diversion direction of the diversion channel 11 where the evaporator 20 is located, and the height direction of the condenser 30 is the same as the diversion direction of the diversion channel 11 where the condenser 30 is located.

[0043] Please refer to Figure 1 and Figure 4 , in some embodiments, both the evaporator 20 and / or the condenser 30 include a plurality of fins 21, and an air flow channel 22 is formed between the plurality of fins 21, and the diversion direction of the air flow channel 22 is consistent with the diversion direction of the diversion channel 11.

[0044] In this way, the fins 21 can increase the contact area between the evaporator 20 and / or the condenser 30 and the air, enabling the refrigerant to quickly absorb the heat in the air, continuously introducing the hot air in the environment into the air flow channel 22, and improving the heat exchange efficiency.

[0045] Specifically, there may be multiple fins 21 provided on the evaporator 20, or there may be multiple fins 21 provided on the condenser 30, or there may be multiple fins 21 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 90, the temperature of the refrigerant drops 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 into condensed water on the evaporator 144 and flow down through the air flow channel 22.

[0046] 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.

[0047] 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 thickness of the fin 21.

[0048] In this way, the thickness of the fin 21 is small, and the gap between the inner container 1100 and the outer shell of the washing appliance 1000 can be fully utilized, reducing the area occupied by the heat pump drying system 1200 on the washing appliance 1000, thereby making the structure of the washing appliance 1000 compact.

[0049] Specifically, as Figure 2 shown, the height direction h of the fin 21 is the flow direction of the diversion channel 11, that is, the vertical direction. The width direction of the fin 21 is the depth direction X of the inner container 1100, and the thickness direction of the fin 21 is the horizontal direction perpendicular to the width direction of the fin 21.

[0050] Please refer to Figure 2 and Figure 3 , in some embodiments, one end of the diversion channel 11 itself extends downward through the evaporator 20 and then extends upward through the condenser 30, and then extends downward to the other end of itself. In this way, the evaporator 20 and the condenser 30 can be arranged at intervals in the diversion channel 11.

[0051] Specifically, the diversion channel 11 can be formed by an integrally formed air duct component 100, or can be formed by connecting multiple air duct components 100. The evaporator 20 and the condenser 30 are respectively located in different air duct components 100. In one embodiment, one end of the diversion channel 11 itself extends downward through the evaporator 20 and then extends horizontally through the condenser 30, and then extends downward to the other end of itself.

[0052] Please refer to Figure 1, in some embodiments, the air duct component 100 includes an intake pipe 70, an exhaust pipe 80, a first fan 40 and a second fan 41. The first fan 40 is disposed on the intake pipe 70, and the second fan 41 is disposed on the exhaust pipe 80. The first fan 40 is configured to drive the gas in the inner tank 1100 to flow towards the evaporator 20, and the second fan 41 is configured to drive the gas to flow back into the inner tank 1100.

[0053] In this way, the intake pipe 70 can guide the gas in the inner tank 1100 to the evaporator 20, and the exhaust pipe 80 can introduce the gas that has successively passed through the evaporator 20 and the condenser 30 into the inner tank 1100, realizing the cyclic flow of the gas between the air duct component 100 and the inner tank 1100. The first fan 40 can provide power for the gas flow in the intake pipe 70, and the second fan 41 can provide power for the gas flow in the exhaust pipe 80.

[0054] Specifically, the evaporator 20, the condenser 30, the intake pipe 70 and the exhaust pipe 80 can be located on the same side of the inner tank 1100, which makes it more convenient to combine the evaporator 20, the condenser 30, the intake pipe 70 and the exhaust pipe 80 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.

[0055] For example, the intake pipe 70 and the exhaust pipe 80 are located on 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.

[0056] The evaporator 20, the intake pipe 70 and the condenser 30, the exhaust pipe 80 can be located on different sides of the inner tank 1100. For example, the evaporator 20 and the intake pipe 70 are located on the left side of the inner tank 1100, and the condenser 30 and the exhaust pipe 80 are located on the right side of the inner tank 1100.

[0057] It should be noted that the left and right sides of the inner tank 1100 mentioned in this application refer to taking the opening of the inner tank 1100 as the front, and the plane at 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 tank 1100, and the right side of the reference plane is the right side of the inner tank 1100.

[0058] 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 operate, they form pressure in the diversion channel 11, causing the gas to circulate along the path of inner tank 1100 → diversion channel 11 → inner tank 1100.

[0059] Please refer to Figure 1 and Figure 2, in some embodiments, the inner container 1100 is provided with a first through hole 1102 and a second through hole 1103. The first blower 40 is disposed adjacent to the first through hole 1102, and the second blower 41 is disposed adjacent to the condenser 30.

[0060] The first through hole 1102 and the second through hole 1103 are holes penetrating through the side wall 1101 of the inner container 1100. The first blower 40 can be installed at one end of the air inlet pipe 70 close to the first through hole 1102 by means of screws. After the first blower 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 blower 41 can be installed at one end of the exhaust pipe 80 close to the condenser 30 by means of screws. After the second blower 41 is started, a positive pressure can be formed on the side facing the inner container 1100, thereby driving the gas to enter the inner container 1100.

[0061] 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 first through hole 1102 is used to export the gas in the washing chamber 1104 to the air duct component 100, and the second through hole 1103 is used to import the gas heated by the condenser 30 into the inner container 1100. The height of the first through hole 1102 is higher than the height of the second through hole 1103.

[0062] Thus, 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 the height of the second through hole 1103. In this way, the height of the exhaust end of the diversion channel 11 is lower than the height of the intake end of the diversion channel 11, so that the blower can more easily extract the humid and hot air in the inner container 1100, and the diversion channel 11 can discharge the dry hot air to a position below the top of the inner container 1100, thereby better drying objects such as tableware.

[0063] Please refer to Figure 1 and Figure 2 , in some embodiments, the first through hole 1102 and the second through hole 1103 are provided on the same side wall 1101 of the inner container 1100. Thus, the air inlet pipe 70 and the exhaust pipe 80 are arranged on the same side wall 1101, and the air inlet pipe 70 and the exhaust pipe 80 can be more conveniently combined with the inner container 1100, making the structure of the air duct component 100 simpler, which is beneficial to improving the reliability of the washing appliance 1000 and reducing the manufacturing cost. 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.

[0064] In some embodiments, the first through-hole 1102 and the second through-hole 1103 may be provided on different side walls 1101 of the inner container 1100. For example, the first through-hole 1102 may be provided on the top wall of the inner container 1100, and the second through-hole 1103 may be provided on the left side wall 1101 or the right side wall 1101 of the inner container 1100.

[0065] In certain embodiments, the second through-hole 1103 is configured to introduce the condensed water formed by the evaporator 20 into the inner container 1100. Thus, the condensed water formed by the evaporator 20 can flow towards the inner container 1100 under the action of gravity through the second through-hole 1103, thereby achieving the collection of the condensed water.

[0066] Please refer to Figure 2 , in certain embodiments, a water receiving portion 50 that is recessed downward is formed at the bottom of the air duct component 100, and the air duct component 100 is further formed with a drain port 51 that communicates with the water receiving portion 50. Thus, the water receiving portion 50 can guide the gas from the air inlet pipe 70 to the exhaust pipe 80, and can also gather the condensed water and discharge the condensed water from the drain port 51, reducing the residue of the condensed water in the air duct component 100. Specifically, the water receiving portion 50 can communicate the air inlet pipe 70 and the exhaust pipe 80. The water receiving portion 50 can be in an inverted triangular shape or an inverted conical shape. The drain port 51 is located at the bottommost end of the water receiving portion 50 and penetrates through the water receiving portion 50 along the wall thickness direction of the water receiving portion 50.

[0067] Please refer to Figure 3 , in certain embodiments, the first through-hole 1102 and the second through-hole 1103 are arranged at intervals along the depth direction X of the inner container 1100. Thus, it is convenient to install the air duct component 100 on the side wall of the inner container 1100 and provide an arrangement space for the evaporator 20 and the condenser 30.

[0068] Specifically, the first through-hole 1102 may be provided at the lower left end of the left side wall 1101 of the inner container 1100, and the second through-hole 1103 may be provided at the upper right end of the left side wall 1101 of the inner container 1100; or the first through-hole 1102 may be provided at the upper left end of the left side wall 1101 of the inner container 1100, and the second through-hole 1103 may be provided at the lower right end of the left side wall 1101 of the inner container 1100.

[0069] Along the depth direction X of the inner container 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.

[0070] Please refer to Figure 1 , in certain embodiments, the washing appliance 1000 includes a base 1400, and the compressor 60 is disposed on the base 1400.

[0071] Thus, the base 1400 can provide support for the compressor 60, enabling the stable installation of the compressor 60. The compressor 60 can be directly installed on the base 1400 or installed on the base 1400 through other media.

[0072] Specifically, the base 1400 is located below the inner tank 1100. The base 1400 can provide support for the inner tank 1100. The compressor 60 and the inner tank 1100 can be arranged side by side on the base 1400.

[0073] 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 operate. 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. The fan 40 drives the heated gas to enter the inner tank 1100 through the second through hole 1103 to dry the dishes. In this way, the cycle is repeated to achieve the effect of drying the dishes.
