[0042] Referring to FIGS. 1-3, the washing appliance 1000 of the present application includes an inner container 1100, a base 1400, a water cup 1300, a heat pump system 1200, and an air duct component 100. The inner container 1100 is provided with a washing chamber 1104. The base 1400 is located below the inner container 1100. The water cup 1300 is installed on the base 1400. The heat pump system 1200 includes a compressor 60, a condenser 30, a throttling device 90, and an evaporator 20, which constitute a closed refrigerant circuit. The compressor 60, the condenser 30, the throttling device 90, and the evaporator 20 are all arranged in a containing space 1410 of the base 1400 and are located on one side of the water cup 1300. The air duct component 100 includes an air duct housing 10 arranged on the base 1400. The evaporator 20 and the condenser 30 are arranged in the air duct housing 10. The evaporator 20 is used to cool the gas flowing out of the inner container 1100. The condenser 30 is used to heat the gas flowing into the inner container 1100.

[0043] In this way, by integrating the compressor 60, the condenser 30, the throttling device 90, and the evaporator 20 on one side of the base 1400, the heat pump system 1200 occupies a smaller space on the base 1400. The heat pump system 1200 is modularly designed. When the washing appliance 1000 is assembled, the number of parts that need to be assembled can be reduced, the assembly effect of the washing appliance 1000 can be improved, and the manufacturing cost of the washing appliance 1000 can be reduced.

[0044] Specifically, the washing appliance 1000 is mainly used for washing various tableware, wherein the inner container 1100 can be used as the main structure of the washing appliance 1000, and the inner container 1100 is formed with a washing chamber 1104 having an opening, and the tableware and the like can be put into the washing chamber 1104 from the opening of the washing chamber 1104. The washing chamber 1104 can be provided with a bracket for carrying and fixing the tableware, and a water cup 1300 placed below the bracket. The water cup 1300 is used to collect and discharge the water flow generated in the washing and condensation process. The washing appliance 1000 is, for example, a dishwasher.

[0045] The base 1400 is used to carry the inner container 1100, the heat pump system 1200, and the air duct component 100 and the like, and the top surface of the base 1400 extends downward to form an accommodation space 1410, and the inner container 1100, the heat pump system 1200, and the air duct component 100 and the like are arranged in the accommodation space 1410.

[0046] The water cup 1300 is provided with a water inlet 1310, and a filter is installed at the water inlet 1310. The water inlet 1310 is located on the side of the water cup 1300 facing the inner container 1100 and is arranged in a groove shape. In the embodiment, the shape of the water inlet 1310 is circular, but is not limited, and the shape of the water inlet 1310 can be various shapes, such as an oval shape, a square shape, etc. The compressor 60, the condenser 30, the throttling device 90, and the evaporator 20 can be located on the left side of the water cup 1300, or on the right side of the water cup 1300.

[0047] The heat pump system 1200 is used to dry the humid hot air flowing out of the inner container 1100, and heat the air after drying, so that the heated and dried air flows into the inner container 1100 again, so as to realize the effect of drying the tableware and the like. It should be pointed out that the above-mentioned dried air is relative to the humid hot air in the inner container 1100, and not refers to the air completely not containing water vapor.

[0048] The evaporator 20 is a heat exchanger in the heat pump system 1200. The evaporator 20 can cool down when the heat pump system 1200 works, thereby absorbing the heat of the air around the evaporator 20 to reduce the temperature of the air around the evaporator 20, so that the gas flowing through the evaporator 20 is condensed to form condensed water, thereby realizing the effect of drying the air.

[0049] The condenser 30 is also a heat exchanger in the heat pump system 1200. The condenser 30 can heat when the heat pump system 1200 works, thereby releasing heat to the air around the condenser 30 to increase the temperature of the air around the condenser 30, so that the gas flowing through the condenser 30 enters the inner container 1100 of the washing appliance 1000 again, thereby realizing the effect of drying the tableware and the like.

[0050] The condenser 30 and the evaporator 20 can be in communication with the compressor 60 through a pipeline 61. The compressor 60, the condenser 30, the throttling device 90 and the evaporator 20, as main components of the heat pump system 1200 of the washing appliance 1000, can be connected in sequence to form a closed refrigerant circuit, so that the refrigerant as the refrigerant can circulate in the closed refrigerant circuit formed by the compressor 60, the condenser 30, the throttling device 90 and the evaporator 20, and the four components can cooperate with each other to enable the heat pump system 1200 to achieve the effect of drying dishes and other objects. When the heat pump system 1200 is in the drying stage, the compressor 60 works to pump the high-temperature and high-pressure refrigerant to the condenser 30 to heat the air, the refrigerant and the air complete heat exchange after the condenser 30, and then flows out of the condenser 30, and then flows into the evaporator 20 after throttling by the throttling device 90 to become low-temperature and low-pressure refrigerant, and then evaporates by heat exchange 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, and further, the throttling device 90 can be an electronic expansion valve.

[0051] The heat pump system 1200 can be directly connected with the base 1400 or indirectly connected with the base 1400. For example, the heat pump system 1200 is fixed on a bottom plate, and the bottom plate is installed on the base 1400, so that the components in the heat pump system 1200 are integrally arranged, and the heat pump system 1200 is convenient to be integrally disassembled and installed.

[0052] The evaporator 20 and the condenser 30 are arranged in the air duct shell 10, so that the air duct shell 10, the evaporator 20 and the condenser 30 can form an integral module, which is convenient to assemble the washing appliance 1000 and is conducive to reducing the manufacturing cost of the washing appliance 1000.

[0053] The air duct component 100 comprises a heat exchange module having a heat exchange function, and the heat exchange module has at least part of the heat exchange components of the heat pump system 1200 of the washing appliance 1000, that is, the heat exchange module at least comprises the evaporator 20 and the condenser 30, so that the washing appliance 1000 can realize the effect of drying dishes and other objects through the air duct component 100.

[0054] The air duct shell 10 is used for ventilation. The air duct shell 10 can be made of plastic or other easily formed materials, so that the air duct shell 10 is easy to manufacture. The air duct shell 10 can be provided with a specific outer structure according to the installation position of the air duct component 100, so that the air duct component 100 and the surrounding components are more compact. The air duct shell 10 is in communication with the inner container 1100.

[0055] Please refer to Fig. 2, in some embodiments, the washing appliance 1000 comprises a breather 1600, which is arranged at one side of the inner tub 1100, and the air inlet pipe 70 and the air outlet pipe 80 are arranged at the opposite side of the inner tub 1100. In this way, the interference of the breather 1600 to the combination of the air inlet pipe 70 and the air outlet pipe 80 with the inner tub 1100 can be reduced, the structure of the air duct component 100 is simpler, and the reliability of the washing appliance 1000 is further improved and the manufacturing cost is lower.

[0056] Specifically, the breather 1600 is provided with a flow meter, which can play a role in calculating the water inflow. The breather 1600 can provide the water softener 1500 with water of a limited flow for softening and washing, and can prevent the backflow of water in the inner tub 1100. The breather 1600 can also communicate the inside and outside of the inner tub 1100, and play a role in balancing the air pressure inside and outside the inner tub 1100, greatly reducing the manufacturing cost and the use and maintenance cost of the washing appliance 1000, and being stable, safe and reliable in work. The breather 1600 can be fixed on the side wall 1101 of the inner tub 1100. It should be noted that the above-mentioned breather 1600 can be purchased on the market, or directly processed and manufactured by a person skilled in the art.

[0057] The breather 1600 can be arranged at the left side of the inner tub 1100, and the air inlet pipe 70 and the air outlet pipe 80 can be arranged at the right side of the inner tub 1100.

In this way, the interference of the soft water device 1500 to the combination of the compressor 60 and the air duct shell 10 with the base 1400 can be reduced, the structure of the washing appliance 1000 is simpler, and the reliability of the washing appliance 1000 is further improved and the manufacturing cost is lower.

[0059] Specifically, the soft water device 1500 can be arranged at the left side of the base 1400, the compressor 60 and the air duct shell 10 can be arranged at the right side of the base 1400, the air duct shell 10 can be arranged at the front side of the base 1400, and the compressor 60 can be arranged at the rear side of the base 1400.

[0060] The softener 1500 is an ion exchange softener 1500 which operates and regenerates the operation process, removes calcium and magnesium ions in water by using sodium cation exchange resin, reduces the hardness of raw water, and achieves the purpose of softening hard water, thereby avoiding the scaling phenomenon of carbonates in pipes, containers, and boilers. It greatly saves investment costs while ensuring smooth production. The commonly used softening technology of the softener 1500 has two kinds. One is to remove calcium and magnesium ions in water by ion exchange resin to reduce water hardness. The other is nanocrystalline TAC technology, namely Template Asisted Crystallization (Template Assisted Crystallization), which uses the high energy generated by nanocrystals to pack the free calcium, magnesium, and bicarbonate ions in water into nanoscale crystals, thereby preventing the formation of free ions into scale. The softener 1500 can be connected to the base 1400 through a water inlet pipe. In an embodiment, the softener 1500 can be fixed on the side wall 1101 of the inner container 1100. It should be noted that the above-mentioned softener 1500 can be purchased on the market, or directly processed and manufactured by those skilled in the art.

[0061] Referring to FIG. 2, in some embodiments, the water cup 1300 is located at the middle position of the base 1400. The center line of the base 1400 extends in the front-rear direction. The softener 1500 and the breather 1600 are located on the left side of the center line. The heat pump system 1200 and the air duct component 100 are located on the right side of the base 1400.

[0062] In this way, the water cup 1300 is located at the middle position of the base 1400, which can concentrate the weight of the collected water at the middle position of the base 1400, so that the washing appliance 1000 is not easy to tip over and the structure is stable. In addition, the softener 1500, the breather 1600, and the heat pump system 1200, the air duct component 100 are located on both sides of the base 1400, which can reduce the interference of the softener 1500 and the breather 1600 on the combination of the heat pump system 1200 and the air duct component 100 with the base 1400, so that the structure of the washing appliance 1000 is simpler, further improves the reliability of the washing appliance 1000, and has lower manufacturing cost.

[0063] Specifically, the water cup 1300 located at the middle position of the base 1400 can mean that the water cup 1300 is located on the center line of the base 1400 extending in the front-rear direction, or that the water cup 1300 is located on the center line of the base 1400 extending in the left-right direction, or that the water cup 1300 is located on the intersection of the center line of the base 1400 extending in the front-rear direction and the center line of the base 1400 extending in the left-right direction.

[0064] Referring to FIG. 2, in some embodiments, the washing appliance 1000 comprises a control system 1700, which is arranged at the front side of the base 1400, and at least partially located between the air duct housing 10 and the water softener 1500.

[0065] In this way, the control system 1700 is used to control the operating state of the washing appliance 1000, which is arranged at the front side of the base 1400, facilitating parameter setting of the control system 1700, and at least partially located between the air duct housing 10 and the water softener 1500, facilitating control of the control system 1700 on the heat pump system 1200 and the water softener 1500.

[0066] Specifically, the control system 1700 can control water temperature, water level, washing time, drying time, etc. For example, the washing appliance 1000 comprises a temperature sensor, which can detect the temperature of the fluid in real time during continuous circulation and heating of the fluid, and feed back the temperature signal to the control system 1700 after the fluid reaches the set temperature, to confirm whether heating needs to be stopped.

[0067] The front side of the base 1400 can be the side of the base 1400 facing the opening of the inner container 1100, and the control system 1700 can be at least partially located between the air duct housing 10 and the water softener 1500, which can be partially located between the air duct housing 10 and the water softener 1500, or entirely located between the air duct housing 10 and the water softener 1500, and the air duct housing 10 and the water softener 1500 can be respectively located at the left and right sides of the base 1400.

For example, the first through hole 1102 and the second through hole 1103 can be 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 at the same time, or can be 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 respectively. 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.

[0076] Please refer to FIG. 4 and FIG. 5, in some embodiments, the height of the first through hole 1102 is higher than the height of the second through hole 1103. Since the hot and humid air in the inner container 1100 flows upward, and the objects such as tableware are located below the top of the inner container 1100, in order to achieve the perfect drying effect, in some embodiments, the height of the first through hole 1102 is higher than the height of the second through hole 1103, so that the height of the exhaust end of the exhaust pipe 80 is lower than the height of the air inlet end of the air inlet pipe 70, so that the air inlet pipe 70 can more easily extract the hot and humid air in the inner container 1100, and the exhaust pipe 80 can exhaust the dry hot air to the position below the top of the inner container 1100, so as to better dry the objects such as tableware.

[0077] Please refer to FIG. 3-FIG. 5, in some embodiments, the evaporator 20, the condenser 30, the air inlet pipe 70 and the exhaust pipe 80 are located on the same side of the inner container 1100.

[0078] Specifically, the evaporator 20, the condenser 30, the air inlet pipe 70 and the exhaust pipe 80 can be located on the same side wall 1101 of the inner container 1100, for example, the evaporator 20, the condenser 30, the air inlet pipe 70 and the exhaust pipe 80 are located on the left side wall 1101, the right side wall 1101 or the rear side wall 1101 of the inner container 1100.

[0079] Please refer to FIG. 3-FIG. 5, in some embodiments, the air inlet pipe 70 and the exhaust pipe 80 are installed on the side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 are located below the bottom wall of the same side of the inner container 1100 as the air inlet pipe 70 and the exhaust pipe 80. In this way, the interference of the evaporator 20 and the condenser 30 with the combination of the air inlet pipe 70 and the exhaust pipe 80 with the inner container 1100 can be reduced, so that the structure of the air duct component 100 is simpler, further improves the reliability of the washing appliance 1000 and has lower manufacturing cost.

[0080] Specifically, the air inlet pipe 70 and the exhaust pipe 80 can be located on the right side wall 1101 of the inner container 1100, and the evaporator 20 and the condenser 30 can be located below the bottom wall of the right side of the inner container 1100.

[0081] In one embodiment, the evaporator 20, the air inlet pipe 70 and the condenser 30, the air outlet pipe 80 can be located at different sides of the inner container 1100, for example, the evaporator 20 and the air inlet pipe 70 are located at the left side of the inner container 1100, and the condenser 30 and the air outlet pipe 80 are located at the right side of the inner container 1100. For example, the evaporator 20 and the air inlet pipe 70 can be located on the left side wall 1101 of the inner container 1100, and the condenser 30 and the air outlet pipe 80 can be located on the right side wall 1101 of the inner container 1100. Alternatively, the air inlet pipe 70 can be located on the left side wall 1101 of the inner container 1100, the evaporator 20 can be located below the bottom wall on the left side of the inner container 1100, the air outlet pipe 80 can be located on the right side wall 1101 of the inner container 1100, and the condenser 30 can be located below the bottom wall on the right side of the inner container 1100.

[0082] It should be noted that the left side and the right side of the inner container 1100 in the present application refer to the face with the same distance from the left side wall 1101 and the right side wall 1101 of the inner container 1100 as the reference face, and the left side of the reference face is the left side of the inner container 1100, and the right side of the reference face is the right side of the inner container 1100.

[0083] Referring to FIGS. 6-8, in some embodiments, the air duct shell 10 includes a main body part 12 and two interface parts 13, both of which are connected to the main body part 12 and are spaced apart on the same side of the main body part 12, one of which is connected to the air inlet pipe 70, and the other of which is connected to the air outlet pipe 80, and the evaporator 20 and the condenser 30 are arranged adjacent to each other in the main body part 12.

[0084] In this way, the air duct shell 10 forms the main body part 12 and the interface part 13 according to different functions, so that the air duct shell 10 can meet the needs of installing the evaporator 20 and the condenser 30, and can realize the function of ventilation. In addition, both of the interface parts 13 are connected to the same side of the main body part 12, so that the air inlet and the air outlet of the air duct shell 10 are located on the same side, which is conducive to the assembly of the air duct shell 10 with other components, reduces the interference between the air duct shell 10 and the surrounding components, and has a simple structure.

[0085] Specifically, the volume of the main body part 12 is greater than that of the interface part 13, so that the main body part 12 can accommodate the evaporator 20 and the condenser 30, and the interface part 13 is more easily connected to other pipes. The main body part 12 is generally cuboid in shape. The evaporator 20 and the condenser 30 can be fixed in the interior of the main body part 12 by means of clamping, threaded connection, etc.

[0086] The interface part 13 protrudes from the surface of the main body part 12. The interface part 13 is similar to a flat tube. The interface part 13 can be located on one side of the main body part 12 in the length direction or the width direction. The shapes, structures and sizes of the two interface parts 13 can be the same, thereby reducing the manufacturing cost of the air duct shell 10.

[0087] Specifically, one end of the air inlet pipe 70 is connected with one of the interface portions 13, and the other end of the air inlet pipe 70 is connected with the inner container 1100. One end of the air outlet pipe 80 is connected with the other interface portion 13, and the other end of the air outlet pipe 80 is connected with the inner container 1100.

[0088] It can be understood that the main body portion 12 and the two interface portions 13 each form a part of the flow channel 11, and when the air duct shell 10 is ventilated, the gas passes through one of the interface portions 13, the main body portion 12 and the other interface portion 13 in sequence.

[0089] The evaporator 20 and the condenser 30 are adjacently arranged in the main body portion 12, which means that the evaporator 20 and the condenser 30 are arranged side by side in the main body portion 12 with a small interval, or the evaporator 20 and the condenser 30 are arranged in close proximity in the main body portion 12.

[0090] Please refer to FIG. 5 and FIG. 8, in some embodiments, the two interface portions 13 extend upward from the main body portion 12 towards the side wall 1101 of the inner container 1100, the air inlet pipe 70 and the air outlet pipe 80 are located above the two interface portions 13, and the interface portions 13, the air inlet pipe 70 and the air outlet pipe 80 are located on the same side of the inner container 1100. In this way, the interface portions 13 can avoid the connection between the inner container 1100 and the air inlet pipe 70 and the air outlet pipe 80, which is conducive to the assembly of the inner container 1100 and other components, reduces the interference between the inner container 1100 and the surrounding components, and has a simple structure.

[0091] Specifically, as in the embodiment of FIG. 8, the interface portion 13 is formed with a vent 131, and the vents 131 of the two interface portions 13 are both upward, and the lower end portions of the air inlet pipe 70 and the air outlet pipe 80 are connected with the two interface portions 13 through the two vents 131 respectively. In this way, the vent 131 can supply the gas to enter the air duct shell 10 from the air inlet pipe 70 downward, and then flow out from the air duct shell 10 upward to the air outlet pipe 80.

[0092] Please refer to FIG. 6 and FIG. 8, 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 the top surface 120 and the interface portion 13 form a containing space 1201 therebetween, the containing space 1201 contains the corner portion of the inner container 1100 connecting the bottom wall and the side wall 1101, and the top surface 120 is attached to the bottom wall of the inner container 1100.

[0093] In this way, the containing space 1201 formed between the top surface 120 and the interface portion 13 can accommodate the inner container 1100, and the interface portion 13 can avoid the connection between the inner container 1100 and the air inlet pipe 70 and the air outlet pipe 80, which is conducive to the assembly of the inner container 1100 and other components, reduces the interference between the inner container 1100 and the surrounding components, and has a simple structure.

[0094] Specifically, the interface portion 13 can be connected with the top surface 120 in a circular arc shape or a bent shape, and an edge of the top surface 120 connected with the interface portion 13 is higher than an edge of the top surface 120 abutting with the bottom wall of the inner container 1100. The accommodation space 1201 is a space jointly formed by a side of the top surface 120 facing the interface portion 13 and a side of the interface portion 13 facing the top surface 120, the bottom wall of the inner container 1100 abutting with the top surface 120, and the side wall 1101 of the inner container 1100 abutting with the interface portion 13.

[0095] Please refer to FIG. 8 and FIG. 9, in some embodiments, the main body portion 12 includes a first shell 121 and a second shell 122 detachably connected with the first shell 121, and the two interface portions 13 are in an integrated structure with the first shell 121. In this way, the first shell 121 is detachably connected with the second shell 122, so that the evaporator 20 and the condenser 30 can be more conveniently installed into the main body portion 12, which is conducive to improving the assembly efficiency of the heat pump system 1200. In addition, the interface portion 13 is in an integrated structure with the first shell 121, which can improve the sealing performance of the connection between the interface portion 13 and the first shell 121, and reduce the risk of air leakage of the flow guide channel 11.

[0096] Specifically, the first shell 121 is located above the second shell 122, and thus the first shell 121 can be referred to as an upper shell, and the second shell 122 can be referred to as a lower shell. The first shell 121 and the second shell 122 can be connected by buckling, screws or the like. The interface portion 13 and the first shell 121 can be formed in an integrated structure by an injection molding process.

[0097] Please refer to FIG. 6-FIG. 9, in some embodiments, the heat pump system 1200 further includes a fan 40, and the fan 40 is used to form an air flow in the flow guide channel 11, and the fan 40 is installed on the outside of the air duct shell 10. In this way, the fan 40 can provide power for the gas flow in the flow guide channel 11. Specifically, the fan 40 can be an axial fan 40 or a centrifugal fan 40, and the fan 40 can be installed on the outside of the second shell 122. When the fan 40 operates, a negative pressure is formed in the flow guide channel 11, so that the gas circulates along the path of the inner container 1100-inlet pipe 70-air duct shell 10-exhaust pipe 80-inner container 1100.

[0098] Please refer to FIG. 6-FIG. 8, in some embodiments, the number of fans 40 is at least two, at least one fan 40 is installed on the air duct shell 10, and at least one fan 40 is arranged on the inlet pipe 70. For example, the fan 40 can be installed on the air duct shell 10 or the inlet pipe 70 by screws. In this way, at least two fans 40 can increase the flow rate of the gas in the flow guide channel 11, thereby enhancing the drying effect of the heat pump system 1200.

[0099] Specifically, the number of the fans 40 can be two, three, four, etc. At least one fan 40 is installed on the main body part 12 of the air duct housing 10, so that the air duct housing 10 can provide more space for the installation of the fan 40. At least a part of one fan 40 can be located in the air flow 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. At least a part of one fan 40 can be located in the air flow channel 11 and downstream of the condenser 30, and at least a part of another fan 40 can be located in the air flow channel 11 and upstream of the evaporator 20.

[0100] At least one fan 40 is arranged on the air inlet pipe 70, so that the air inlet pipe 70 can provide more space for the installation of the fan 40. At least a part of one fan 40 can be located in the air inlet 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. At least a part of one fan 40 can be located at the air inlet end of the air inlet pipe 70, and at least a part of another fan 40 can be located at the air outlet end of the air inlet pipe 70.

[0101] In some embodiments, the fan 40 is only installed on the air duct housing 10. That is, the heat pump system 1200 is provided with at least one fan 40 in the air flow channel 11 to provide power for the gas flow in the air flow channel 11.

[0102] Since the air flow channel 11 between the main body part 12 and the interface part 13 is not straight, in order to reduce the resistance of the gas flow, the fan 40 adopts a centrifugal fan 40, and the air outlet of the fan 40 faces the interface part 13, so that the gas can be directly discharged to the interface part 13.

[0103] Please refer to FIG. 1 and FIG. 6, in some embodiments, the heat pump system 1200 further comprises a tray 50, the compressor 60 and the air duct housing 10 are all installed on the tray 50 and located below the inner container 1100, and the compressor 60 and the air duct housing 10 are arranged in the depth direction X of the inner container 1100. In this way, the compressor 60 and the air duct housing 10 form a whole through the tray 50, which is conducive to the installation of the heat pump system 1200 as a whole and improves the assembly efficiency of the washing appliance 1000.

[0104] Specifically, the tray 50 can be mounted on the base 1400 of the washing appliance 1000. Since the depth direction X of the inner tub 1100 has more installation space, the compressor 60 and the air duct housing 10 are arranged along the depth direction X of the inner tub 1100, which can reasonably utilize the space of the washing appliance 1000 and reduce the interference between the compressor 60, the air duct housing 10 and other components. The depth direction X of the inner tub 1100 is the direction in which the opening of the washing chamber 1104 extends inward.

[0105] Referring to FIG. 2, in some embodiments, the compressor 60 is vertically arranged on the base 1400. In this way, the compressor 60 is vertically arranged on the base 1400, and the space occupied by the compressor 60 on the base 1400 is smaller than that when the compressor 60 is horizontally arranged on the base 1400, thereby improving the space utilization of the base 1400 and making the structure of the washing appliance 1000 more compact.

[0106] Referring to FIGS. 4 and 8, in some embodiments, the exhaust pipe 80 has a plurality of exhaust openings 81, and the plurality of exhaust openings 81 are arranged along the height direction of the inner tub 1100. In this way, the plurality of exhaust openings 81 of the exhaust pipe 80 are arranged along the height direction of the inner tub 1100, so that the exhaust openings 81 can exhaust the dried hot air to different positions of the inner tub 1100, thereby achieving a better drying effect.

[0107] The number of exhaust openings 81 can be two, three, four, etc., and the application does not limit the specific number of exhaust openings 81.

[0108] Referring to FIG. 8, in some embodiments, the exhaust pipe 80 has a first exhaust section 82 and a plurality of second exhaust sections 83, the end of each second exhaust section 83 is formed with an exhaust opening 81, and the middle part of the second exhaust section 83 is curved upward. In this way, 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 curved upward, so that the condensed water formed in the exhaust pipe 80 cannot re-enter the inner tub 1100, which is conducive to improving the drying efficiency of the washing appliance 1000. In addition, the middle part of the second exhaust section 83 is curved upward, which can also block the water in the inner tub 1100 from directly entering the exhaust pipe 80, thereby improving the reliability of the normal operation of the heat pump system 1200.

[0109] Referring to FIG. 1, in some embodiments, the air duct component 100 is formed with a flow guide channel 11, both ends of the flow guide channel 11 communicate with the washing chamber 1104, the evaporator 20 and the condenser 30 are arranged in the same flow guide channel 11, and along the flow direction of the flow guide channel 11, the evaporator 20 is located upstream of the condenser 30. The heat pump system 1200 is configured to first cool and dehumidify the air flowing out of the inner tub 1100 by the evaporator 20, and then heat the air by the condenser 30 before returning the air to the inner tub 1100.

[0110] In this way, by arranging the evaporator 20 to be upstream of the condenser 30, the evaporator 20 and the condenser 30 cooperate with each other to first cool and dry the air in the air flow channel 11 and then heat the air, so that the washing appliance 1000 can use the heat pump system 1200 to achieve the effect of drying the dishes and the like.

[0111] Specifically, the air duct component 100 forms the air flow channel 11 to achieve the effect of ventilation, so that the gas can circulate between the inner tub 1100 of the washing appliance 1000 and the heat pump system 1200 to achieve the effect of drying the dishes and the like. The air flow channel 11 can be arranged in a curved shape or the like to meet the flow requirements of the air flow. The cross-sectional area of the air flow channel 11 at different positions can be different. For example, the cross-sectional area of the air flow channel 11 at the position for accommodating the evaporator 20 and the condenser 30 is larger, and the cross-sectional area at other positions is smaller.
