[0032] Please refer to Figure 1 , the washing appliance 1000 according to the embodiment of the present application includes an inner container 1100, a heat pump drying system 1200, and a heat pipe assembly 1400. The inner container 1100 is provided with a washing chamber 1110. The heat pump drying system 1200 includes a duct component 110, 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 110 communicates with the washing chamber 1110. The evaporator 20 and the condenser 30 are both disposed in the duct component 110. 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. The heat pipe assembly 1400 includes a hot end 1410 and a cold end 1420. The hot end 1410 and the cold end 1420 are both disposed in the duct component 110. The cold end 1420 is used to cool the gas flowing out of the inner container 1100, and the hot end 1410 is used to heat the gas flowing into the inner container 1100.

[0033] In the washing appliance 1000 according to the embodiment of the present application, the evaporator 20 and the cold end 1420 can perform secondary cooling and dehumidification on the humid and hot air in the duct component 110, improving the dehumidification ability of the heat pump drying system 1200. The condenser 30 and the hot end 1410 can perform secondary heating on the dried air in the duct component 110, improving the temperature rise of the heat pump drying system 1200, thereby improving the drying effect of the washing appliance 1000.

[0034] Specifically, the washing appliance 1000 is mainly used for washing various tableware. Among them, the inner container 1100 can be used as the main structure of the washing appliance 1000, and the washing chamber 1110 can be used as the place for actually cleaning items. A bracket for carrying and fixing tableware, and a water cup 1300 placed below the bracket can be provided in the washing chamber 1101. The water cup 1300 is used to collect and hold the water flow generated during the washing process. The washing appliance 1000 is, for example, a dishwasher.

[0035] The heat pump drying system 1200 is used to dry the humid and hot air flowing out of the inner tank 1100 and heat the dried air, so that the heated and dried air flows into the inner tank 1100 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 inner tank 1100, and it does not mean that the air contains no water vapor at all.

[0036] The evaporator 20 is a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 is working, 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.

[0037] The evaporator 20 is generally flat. The evaporator 20 can be placed vertically, or rather, the thickness direction of the evaporator 20 is generally horizontally arranged, and the thickness direction of the evaporator 20 is substantially parallel to the central axis of the diversion channel 11, so as to increase the contact area between the gas in the diversion channel 11 and the evaporator 20, which is beneficial to improving the drying effect on the air flowing through the evaporator 20.

[0038] The condenser 30 is also a heat exchanger in the heat pump drying system 1200. When the heat pump drying system 1200 is working, the condenser 30 can heat, thereby absorbing the heat of heating 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.

[0039] The condenser 30 is generally flat. The condenser 30 can be placed vertically, or rather, the thickness direction of the condenser 30 is generally horizontally arranged, and the thickness direction of the condenser 30 is substantially parallel to the central axis of the diversion channel 11, so as to increase the contact area between the gas in the diversion channel 11 and the condenser 30, which is beneficial to improving the heating effect on the air flowing through the condenser 30.

[0040] The condenser 30 and the evaporator 20 can be connected to the compressor 60 through the 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 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 formed by 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 inner tank 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.

[0041] The heat pipe assembly 1400 is a device that transfers thermal energy from one location to another. The heat pipe assembly 1400 includes a sealed housing that contains a working fluid. In some embodiments, the working fluid can be water. In other embodiments, suitable working fluids for the heat pipe assembly 1400 include acetone, methanol, ethanol, or toluene. In other embodiments, any suitable fluid can be used as the working fluid, for example, it is compatible with the material of the housing and suitable for the desired operating temperature range. The heat pipe assembly 1400 extends between the condenser 30 and the evaporator 20. The working fluid contained in the housing of the heat pipe assembly 1400 absorbs thermal energy in the evaporator 20, and the working fluid goes from the evaporator 20 to the condenser 30 in a gaseous state. The gaseous working fluid condenses into a liquid state, thereby releasing thermal energy at the condenser 30.

[0042] The heat pipe assembly 1400 can include an internal core structure (not shown) to transport the liquid working fluid from the condenser 30 to the evaporator 20 through capillary flow. In some embodiments, the heat pipe assembly 1400 can be constructed and arranged such that the liquid working fluid returns to the evaporator 20 only by gravity flow. For example, the washing appliance 1000 can be constructed such that the heat pipe assembly 1400 can be arranged along the vertical direction V, where the condenser 30 is located above the evaporator 20, so that the liquid condensed working fluid can flow out of the condenser 30 and be transported to the evaporator 20 by gravity. In such an embodiment, the liquid working fluid can return to the evaporator 20 by gravity, and the core structure can be omitted.

[0043] Please refer to Figure 1, in some embodiments, the hot end 1410 and the cold end 1420 are connected by a heat-insulating connector 1430. In this way, the heat-insulating connector 1430 can prevent heat from being neutralized between the hot end 1410 and the cold end 1420 through the connector. The heat-insulating connector 1430 can be a plastic connector or other connectors with low thermal conductivity.

[0044] Please refer to Figure 1 , in some embodiments, the air duct component 110 is formed with a diversion channel 11. Both ends of the diversion channel 11 communicate with the washing chamber 1110. The evaporator 20, the condenser 30, the hot end 1410, and the cold end 1420 are arranged in the same diversion channel 11. Along the diversion direction of the diversion channel 11, the evaporator 20 is located upstream of the condenser 30.

[0045] In this way, 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 washing appliance 1000 can use the heat pump drying system 1200 to achieve the effect of drying items such as tableware.

[0046] Specifically, the diversion channel 11 formed by the air duct component 110 is used to achieve the effect of ventilation, 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 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.

[0047] In one embodiment, the inner container 1100 is formed with an air inlet 1120 and an air outlet 1130. One end of the diversion channel 11 communicates with the washing chamber 1110 through the air outlet 1130, and the other end communicates with the washing chamber 1110 through the air inlet 1120.

[0048] Please refer to Figure 1 , in some embodiments, along the diversion direction of the diversion channel 11, the cold end 1420 is located upstream of the hot end 1410.

[0049] In this way, the air duct component 110 can first cool and dry and then heat the air in the diversion channel 11, so that the washing appliance 1000 can use the heat pump drying system 1200 to achieve the effect of drying items such as tableware.

[0050] Specifically, it can be that the cold end 1420 and the hot end 1410 are located between the evaporator 20 and the condenser 30, or the evaporator 20 is located between the cold end 1420 and the hot end 1410, or the condenser 30 is located between the cold end 1420 and the hot end 1410.

[0051] Please refer to Figure 1 , in some embodiments, along the flow direction of the diversion channel 11, the cold end 1420 is located upstream of the evaporator 20. In this way, the cold end 1420 can pre-cool the humid and hot air entering the evaporator 20, improve the dehumidification ability of the heat pump drying system 1200, and save energy consumption.

[0052] Please refer to Figure 1 , in some embodiments, the hot end 1410 is located between the evaporator 20 and the condenser 30. In this way, the hot end 1410 can pre-heat the dried air entering the condenser 30, increase the temperature rise of the heat pump drying system 1200, and thus improve the drying effect of the washing appliance 1000.

[0053] Please refer to Figure 1 , in some embodiments, along the flow direction of the diversion channel 11, the cold end 1420, the evaporator 20, the hot end 1410, and the condenser 30 are arranged in sequence. The washing appliance 1000 is configured to first cool and dehumidify the air flowing out of the inner container 1100 by the cold end 1420 and the evaporator 20, and then heat it by the hot end 1410 and the condenser 30 and return it to the inner container 1100. In this way, the gas from the inner container 1100 can first be cooled by the cold end 1420, and then cooled and dehumidified by the evaporator 20. The dried gas is first pre-heated by the hot end 1410 and then heated by the condenser 30 and then returned to the inner container 1100 again. In this way, the cycle is realized to achieve the effect of drying tableware.

[0054] Specifically, the cold end 1420, the evaporator 20, the hot end 1410, and the condenser 30 can be arranged at intervals or adjacent to each other. For example, the cold end 1420 and the evaporator 20 are adjacent to each other, the hot end 1410 and the condenser 30 are adjacent to each other, and the evaporator 20 and the hot end 1410 are arranged at intervals.

[0055] Please refer to Figure 1 , in some embodiments, the air duct component 110 includes an air duct housing 10, an air inlet pipe 70, and an air outlet pipe 80. The air inlet pipe 70 and the air outlet pipe 80 are both communicated with the air duct housing 10. The air inlet pipe 70 and the air outlet pipe 80 are both connected to the inner container 1100. The evaporator 20 and the condenser 30 are arranged at intervals in the air duct housing 10.

[0056] Thus, 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 direct the gas that has passed through the evaporator 20 and the condenser 30 in sequence into the inner tank 1100. The intake pipe 70, the air duct housing 10, and the exhaust pipe 80 together form the air duct component 110, realizing the circulating flow of gas between the air duct housing 10 and the inner tank 1100. Additionally, 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 whole, facilitating the assembly of the washing appliance 1000 and being beneficial to reducing the manufacturing cost of the washing appliance 1000.

[0057] Specifically, the air duct housing 10 is for ventilation. The entire air duct housing 10 can be made of materials such as plastic that are easy to mold, making the air duct housing 10 easy to manufacture. The air duct housing 10 can be set to a specific external shape structure according to the installation position of the heat pump drying system 1200, so that the heat pump drying system 1200 can cooperate more tightly with the surrounding components. The air duct housing 10 communicates 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] Since the humid and hot air in the inner tank 1100 flows upward, and objects such as tableware are located below the top of the inner tank 1100, in order to achieve a better drying effect, in some embodiments, the end of the intake pipe 70 connected to the inner tank 1100 is higher than the end of the exhaust pipe 80 connected to the inner tank 1100. This enables the intake pipe 70 to more easily extract the humid and hot air in the inner tank 1100, and the exhaust pipe 80 can discharge the dry hot air to a position below the top of the inner tank 1100, thereby better drying objects such as tableware.

[0060] In some embodiments, the intake pipe 70 and the exhaust pipe 80 can both be connected to the side wall of the inner tank 1100. For example, the intake pipe 70 and the exhaust pipe 80 can both be connected to the left side wall, the right side wall, or the rear side wall of the inner tank 1100, thereby reducing the interference between the intake pipe 70 and the exhaust pipe 80 and other components of the washing appliance 1000 and improving the reliability of the washing appliance 1000.

[0061] In some embodiments, the intake pipe 70 can be connected to the top wall of the inner tank 1100, while the exhaust pipe 80 is connected to the side wall of the inner tank 1100.

[0062] Please refer to [[ID=#19]] Figure 1, in some embodiments, the heat pump drying system 1200 includes a fan 40, and the fan 40 is used to form an air flow in the diversion channel 11. 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 40 or a centrifugal fan 40.

[0063] In some embodiments, the fan 40 is installed on the air duct housing 10. For example, the fan 40 can be installed on the air duct housing 10 by means of screws. Thus, the fan 40 and the air duct housing 10 form an integral body, making the heat pump drying system 1200 easy to assemble.

[0064] Specifically, 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, thereby sucking the air around the condenser 30 to make the gas flow.

[0065] Please refer to Figure 2 , in some embodiments, the air duct component 110 is formed with a first diversion channel 111 and a second diversion channel 112 independent of the first diversion channel 111. The first diversion channel 111 communicates with the washing chamber 1110, and both ends of the second diversion channel 112 communicate with the washing chamber 1110. The evaporator 20 and the cold end 1420 are spaced apart and arranged in the first diversion channel 111, and the condenser 30 and the hot end 1410 are spaced apart and arranged in the second diversion channel 112.

[0066] Thus, placing the evaporator 20 and the condenser 30 in two independent diversion channels 11 respectively can simplify the design and length of the diversion channel 11 and improve the gas flow efficiency and flow rate.

[0067] Specifically, the shapes and sizes of the first diversion channel 111 and the second diversion channel 112 can be the same or different. The first diversion channel 111 and the second diversion channel 112 can communicate with the same side or different sides of the washing chamber 1110. The evaporator 20 and the cold end 1420 can be fixed inside the air duct housing 10 forming the first diversion channel 111 by means of snap connection, threaded connection, etc., and the condenser 30 and the hot end 1410 can be fixed inside the air duct housing 10 forming the second diversion channel 112 by means of snap connection, threaded connection, etc.

[0068] Please refer to Figure 2, in some embodiments, both ends of the first diversion channel 111 communicate with the washing chamber 1110, and the washing appliance 1000 is configured to return the air flowing out of the inner container 1100 to the inner container 1100 after being cooled by the cold end 1420 and the evaporator 20, and, the air flowing out of the inner container 1100 is returned to the inner container 1100 after being heated by the hot end 1410 and the condenser 30. Thus, the first diversion channel 111 can enable the air after cooling and dehumidification to enter the washing chamber 1110 for recycling, increasing the utilization rate of the gas.

[0069] Please refer to Figure 2 , in some embodiments, the inner container 1100 is formed with an air inlet 1120 and an air outlet 1130. One end of the first diversion channel 111 communicates with the washing chamber 1110 through the air outlet 1130, and the other end communicates with the washing chamber 1110 through the air inlet 1120. The air inlet 1120 and the air outlet 1130 are located on different side walls of the inner container 1100.

[0070] Thus, both ends of the first diversion channel 111 are connected to different side walls of the inner container 1100, increasing the gas flow path, thereby improving the gas condensation effect.

[0071] Specifically, the air inlet 1120 and the air outlet 1130 penetrate through the side wall of the inner container 1100 along the wall thickness direction of the inner container 1100. The inner container 1100 may be formed with two air inlets 1120 and two air outlets 1130.

[0078] Specifically, it can be that along the diversion direction of the first diversion channel 111, the cold end 1420 is located upstream of the evaporator 20, or along the diversion direction of the second diversion channel 112, the hot end 1410 is located upstream of the condenser 30, or along the diversion direction of the first diversion channel 111, the cold end 1420 is located upstream of the evaporator 20, and along the diversion direction of the second diversion channel 112, the hot end 1410 is located upstream of the condenser 30.

[0079] In one embodiment, the number of the fans 40 is two. The two fans 40 are respectively located in the first diversion channel 111 and the second diversion channel 112. One of the fans 40 can be located upstream of the cold end 1420 or between the cold end 1420 and the evaporator 20, and the other fan 40 can be located upstream of the hot end 1410 or between the hot end 1410 and the condenser 30.

[0080] In summary, please refer toFigure 1 In one embodiment, after the washing appliance 1000 finishes washing and enters the drying mode, the heat pump drying system 1200, the heat pipe assembly 1400, and the fan 40 start to work. The fan 40 causes the gas to circulate between the inner tank 1100 and the diversion channel 11. In the diversion channel 11, the gas from the washing chamber 1110 is pre-cooled by the cold end 1420 and then passes through the evaporator 20. The evaporator 20 can further cool the pre-cooled air and form condensed water. The air dried by the evaporator 20 is pre-heated by the hot end 1410 and then passes through the condenser 30. The condenser 30 can further heat the pre-heated air. The heated air enters the inner tank 1100 to dry the tableware. By circulating in this way, the effect of drying the tableware is achieved.
