[0040] Please see Figure 1 The washing appliance 1000 of this application includes an inner tank 1100 and a drain component 100 of a heat pump device. The washing appliance 1000 is mainly used for washing various types of tableware. The inner tank 1100 can serve as the main structure of the washing appliance 1000. The inner tank 1100 forms a washing chamber 1101 with an opening, allowing tableware and other objects to be placed into the washing chamber 1101 through the opening. The washing chamber 1101 may be equipped with a bracket for supporting and securing tableware, and a water cup 1300 placed below the bracket. The water cup 1300 is used to collect and drain water generated during the washing and condensation processes. The washing appliance 1000 is, for example, a dishwasher.

[0041] Please see Figures 2-4 In some embodiments, the drainage component 100 includes a heat pump system 1200 and a drainage assembly 300. The heat pump system 1200 includes a heat exchange housing 10 and an evaporator 20. The evaporator 20 is used to cool the gas flowing out from the inner liner 1100. A water receiving tray 14 is provided inside the heat exchange housing 10. The water receiving tray 14 is located below the evaporator 20. The heat exchange housing 10 is provided with a drain port 15 communicating with the water receiving tray 14. The drainage assembly 300 includes a water pump 310. The water pump 310 is installed on the heat exchange housing 10 and is used to draw condensate from the water receiving tray 14 through the drain port 15.

[0042] In the washing appliance 1000 of this application embodiment, the evaporator 20 of the heat pump system 1200 can dry the environment in the inner tank 1100. During the operation of the heat pump system 1200, the water pump 310 can extract the condensate located below the evaporator 20, so that the heat pump system 1200 can maintain normal operation. The water pump 310 is installed on the heat exchange housing 10, which can make full use of the space around the heat exchange housing 10 and make the water pump 310 closer to the drain outlet 15, which is beneficial for the water pump 310 to pump water, improves the overall structural compactness of the washing appliance 1000, and makes the washing appliance 1000 more miniaturized.

[0043] Specifically, the heat pump system 1200 is used to dry the hot and humid air flowing out of the inner tank 1100, thereby drying tableware and other items. The washing appliance 1000 is, for example, a dishwasher. It should be noted that the dried air mentioned above is relative to the hot and humid air inside the inner tank 1100, and does not mean that the air contains absolutely no moisture.

[0044] The heat exchange housing 10 is used for ventilation. The heat exchange housing 10 can be made of easily moldable materials such as plastic, making it easy to manufacture. The ventilation channel formed by the heat exchange housing 10 is used to achieve the effect of ventilation, allowing gas to circulate between the inner tank 1100 of the washing appliance 1000 and the heat exchange housing 10, so as to achieve the effect of drying tableware and other items.

[0045] The heat pump system 1200 is a module with heat exchange function. The heat pump system 1200 has at least some of the components of the heat pump system 1200 of the washing appliance 1000, enabling the washing appliance 1000 to achieve the effect of drying tableware and other items through the heat pump system 1200.

[0046] The heat exchange housing 10 can be configured with a specific external structure according to the installation location of the heat pump system 1200, so that the heat pump system 1200 can fit more compactly with the surrounding components. The heat exchange housing 10 is connected to the inner liner 1100.

[0047] Evaporator 20 is a heat exchanger in heat pump system 1200. When heat pump system 1200 is working, evaporator 20 can cool by absorbing heat from the air around evaporator 20 to lower the temperature of the surrounding air, so that the gas flowing through evaporator 20 condenses to form condensate water, thus achieving the effect of drying the air.

[0048] The evaporator 20 is generally flat. The evaporator 20 can be placed vertically, or in other words, the length of the evaporator 20 is arranged horizontally, and the length of the evaporator 20 is roughly parallel to the flow direction of the heat exchange shell 10, so as to increase the contact area between the gas in the heat exchange shell 10 and the evaporator 20, which is beneficial to improving the drying effect on the air flowing through the evaporator 20.

[0049] The evaporator 20 can condense water vapor in the air to form condensate. The condensate drips down under the action of gravity. Therefore, the drip tray 14 can catch the condensate formed by the evaporator 20, reducing the risk of condensate flowing to other places and causing adverse effects.

[0050] In one example, the water receiving tray 14 may be formed on the inner surface of the heat exchange shell 10, or in other words, the water receiving tray 14 and the heat exchange shell 10 may be an integral structure. For example, the surface of the heat exchange shell 10 may be recessed or inclined to form the water receiving tray 14.

[0051] In another example, the water receiving tray 14 and the heat exchange shell 10 are detachable structures, which allows the heat exchange shell 10 and the water receiving tray 14 to be molded independently and then assembled together, making the shape of the heat exchange shell 10 simpler and reducing the manufacturing cost of the heat exchange shell 10.

[0052] The main body of the water pump 310 can be cylindrical. The water pump 310 is connected to the drain outlet 15, so that the condensate in the water receiving pan 14 can be pumped out and discharged through the drain outlet 15.

[0053] Please see Figure 4 In some embodiments, a mounting bracket 320 is provided on the side wall of the heat exchange housing 10, and the mounting bracket 320 is provided with a mounting hole 321, in which the water pump 310 is inserted.

[0054] Thus, the water pump 310 is mounted on the side wall of the heat exchange housing 10 via the mounting bracket 320, which makes the installation of the water pump 310 more stable.

[0055] Specifically, in one example, the mounting bracket 320 is elastic. Because the mounting bracket 320 is elastic, it can absorb the vibration generated by the water pump 310 during operation, thereby reducing the noise generated by the washing appliance 1000, improving the user experience of the washing appliance 1000, and also extending the service life of components such as the heat exchange housing 10.

[0056] The mounting bracket 320 can be made of elastic materials such as silicone. The water pump 310 is inserted into the mounting hole 321, so that the mounting bracket 320 can cover at least a part of the water pump 310, thereby improving the ability of the mounting bracket 320 to absorb the vibration generated by the water pump 310.

[0057] The shape of the mounting hole 321 matches the shape of the water pump 310 so that the mounting assembly fits more tightly with the water pump 310. For example, when the body of the water pump 310 is cylindrical, the mounting hole 321 is also a cylindrical hole.

[0058] Please see Figures 4-7 In some embodiments, the heat exchange housing 10 is provided with a mounting post 330 on its side wall, and the mounting bracket 320 is provided with a connecting part 323 connected to the mounting post 330. The connecting part 323 is provided with a mounting hole 3231. The mounting post 330 passes through the mounting hole 3231 to suspend the water pump 310 on the mounting bracket 320 on the heat exchange housing 10.

[0059] This allows the water pump 310 to be suspended on the heat exchange housing 10, reducing contact between the water pump 310 and other components of the washing appliance 1000, and reducing the transmission of vibration from the water pump 310 to other components of the washing appliance 1000 during operation, thereby reducing the noise of the washing appliance 1000. In addition, the mounting hole 3231 also makes it easier to install the mounting bracket 320 on the heat exchange housing 10.

[0060] Specifically, the mounting bracket 320 may include a mounting portion 322, which has a mounting hole 321. The mounting portion 322 may be generally cylindrical, and the connecting portion 323 may protrude tangentially from the mounting portion 322. In one example, the mounting portion 322 and the connecting portion 323 are integrally molded. For example, the mounting portion 322 and the connecting portion 323 may be formed by silicone injection molding.

[0061] The mounting column 330 and the heat exchange shell 10 can be an integral structure. The mounting hole 3231 is a through hole, through which the mounting column 330 can be inserted, allowing the mounting bracket 320 to be hung on the mounting column 330. To ensure more stable installation of the mounting bracket 320, there can be multiple mounting columns 330 and multiple connecting parts 323, with each mounting column 330 and connecting part 323 corresponding to the others, and each connecting part 323 having a mounting hole 3231.

[0062] Multiple connecting parts 323 can be disposed at different positions on the mounting part 322. In one example, there are four connecting parts 323, with two connecting parts 323 disposed on the upper side of the mounting part 322 and the other two connecting parts 323 disposed on the lower side of the mounting part 322, and each connecting part 323 is mounted on a corresponding mounting post 330.

[0063] Please see Figures 5-7 In some embodiments, the mounting post 330 includes a post body 331 and a hook-shaped portion 332 formed on the post body 331. The post body 331 is connected to the heat exchange housing 10 and passes through the mounting hole 3231. The hook-shaped portion 332 abuts against the end face of the mounting hole 3231 to prevent the connecting portion 323 from detaching from the mounting post 330. In this way, the post body 331 can provide a mounting position for the mounting bracket 320, and the hook-shaped portion 332 prevents the connecting portion 323 from detaching from the mounting post 330, making the mounting bracket 320 more stable when mounted on the heat exchange housing 10.

[0064] In one example, as mentioned above, since the mounting bracket 320 is elastic, it can be stretched during the process of mounting the mounting bracket 320 onto the heat exchange housing 10, so that the edge of the mounting hole 3231 extends beyond the edge of the hook portion 332, so that the connecting portion 323 can be hung on the mounting column 330.

[0065] In some embodiments, the mounting post 330 is disposed perpendicular to the side wall of the heat exchange housing 10, the mounting hole 321 has an opening on one side in the horizontal direction, and the water pump 310 is horizontally mounted on the heat exchange housing 10.

[0066] Specifically, please refer to Figures 2-4 In some embodiments, the water pump 310 is located adjacent to the drain outlet 15, and the drainage assembly 300 also includes a drain pipe 340 that connects the drain outlet 15 and the water pump 310, and the drain pipe 340 is at least partially engaged on the heat exchange housing 10.

[0067] Thus, the drain pipe 340 can extract water from the water tray 14. The water pump 310 is located near the drain outlet 15, which shortens the length of the drain pipe 340 and reduces the resistance to the flow of condensate. This not only makes the washing appliance 1000 more compact but also reduces the power and size of the water pump 310. The drain pipe 340 is at least partially mounted on the heat exchange housing 10, making the position of the drain pipe 340 more stable and improving the compactness of the connection between the drain pipe 340 and the heat exchange housing 10.

[0068] Specifically, the drain pipe 340 can be a flexible hose, or in other words, the drain pipe 340 is easily bendable, making it easy to connect the drain outlet 15 and the water pump 310. For example... Figure 4As shown, a limiting piece 16 can be provided on the heat exchange shell 10. A groove 161 is formed between the limiting piece 16 and the heat exchange shell 10. The drain pipe 340 is locked in the groove 161, thereby limiting the position of the drain pipe 340.

[0069] Please see Figure 5 , Figure 6 and Figure 8 In some embodiments, the heat pump system 1200 further includes a fan 40 disposed within the heat exchange housing 10, the fan 40 having a Hall sensor 41, a water pump 310 disposed adjacent to the fan 40, the water pump 310 having a metal housing 311, the metal housing 311 being offset from the Hall sensor 41 along the axial direction of the fan 40.

[0070] In this way, the fan 40 can generate airflow in the duct component 100, allowing the gas to circulate between the inner liner 1100 and the duct component 100. The metal housing of the water pump 310 is offset from the Hall sensor 41 of the fan 40 along the axial direction of the fan 40. This reduces the influence of the water pump 310 on the Hall sensor 41 and improves the accuracy of the data detected by the Hall sensor 41.

[0071] Specifically, the fan 40 can be an axial flow fan or a centrifugal fan. The fan 40 can be embedded within the heat exchange housing 10 to ensure stable positioning. The Hall sensor 41 can be used to detect the rotational speed of the fan 40. For example, the rotor of the fan 40 can be equipped with magnetic elements such as magnets, forming a magnetic field around the magnetic elements. The Hall sensor 41 detects the rotational speed of the fan 40 by measuring the strength of the magnetic field.

[0072] The metal casing 311 of the water pump 310 can be made of steel. The steel casing can affect the magnetic field, which in turn can affect the detection of the Hall sensor 41. When the metal casing 311 of the water pump 310 and the Hall sensor 41 are offset, that is, when the metal casing 311 of the water pump 310 and the Hall sensor 41 are not aligned with the axis of the fan 40, the influence of the metal casing 311 of the water pump 310 on the Hall sensor 41 is smaller, thereby improving the accuracy of the detection data of the Hall sensor 41.

[0073] Please see Figure 3 , Figure 5 and Figure 8 In some embodiments, the size of the pump 310 is smaller than the size of the heat exchange housing 10 along the axial direction of the pump 310.

[0074] Thus, the axis of the water pump 310 is set horizontally, which makes it easier for the water pump 310 to draw condensate into the water pump 310 and then discharge it.

[0075] Furthermore, the size of the water pump 310 is smaller than that of the heat exchange housing 10, or in other words, the water pump 310 is smaller in volume and occupies less space, thereby making the washing appliance 1000 more compact.

[0076] Please see Figure 3 , Figure 5 and Figure 8 In some embodiments, the fan 40 is a centrifugal fan, and the axis of the fan 40 is perpendicular to the axis of the water pump 310. Thus, when the fan 40 is a centrifugal fan, it draws in air axially and discharges air tangentially. The perpendicularity of the axis of the fan 40 to the axis of the water pump 310 reduces the space occupied by the fan 40 and the water pump 310 along the axial direction of the fan 40, thereby improving the structural compactness of the washing appliance 1000.

[0077] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the heat pump system 1200 further includes a compressor 60, a condenser 30, and a throttling device 90. The compressor 60, condenser 30, throttling device 90, and evaporator 20 are connected in sequence to form a closed refrigerant circuit. The evaporator 20 and condenser 30 are spaced apart in the heat exchange housing 10. The condenser 30 is used to heat the gas flowing into the inner liner 1100.

[0078] Thus, the condenser 30 also functions as a heat exchanger in the heat pump system 1200. When the heat pump system 1200 is operating, the condenser 30 generates heat, thereby absorbing heat from the surrounding air to raise its temperature. This allows the gas flowing through the condenser 30 to re-enter the inner tank 1100 of the washing appliance 1000, achieving the effect of drying tableware and other items.

[0079] The condenser 30 is roughly flat. The condenser 30 can be placed vertically, or in other words, the length of the condenser 30 is roughly horizontal, and the length of the condenser 30 is roughly parallel to the flow direction of the heat exchange shell 10, so as to increase the contact area between the gas in the heat exchange shell 10 and the condenser 30, which is beneficial to improving the heating effect of the air flowing through the condenser 30.

[0080] In this embodiment, the evaporator 20 is located upstream of the condenser 30. Thus, the evaporator 20 and the condenser 30 cooperate with each other to cool and dry the air in the ventilation duct before heating it, thereby enabling the washing appliance 1000 to dry tableware and other items using the heat pump system 1200.

[0081] Please see Figure 1 and Figure 2In some embodiments, the intake pipe 70 and the exhaust pipe 80 are both connected to the inner liner 1100 and the heat exchange shell 10. The intake pipe 70 can guide the gas in the inner liner 1100 into the heat exchange shell 10, and the exhaust pipe 80 can guide the gas that has passed through the evaporator 20 and the condenser 30 into the inner liner 1100. The intake pipe 70, the heat exchange shell 10 and the exhaust pipe 80 together form the air duct component 100, realizing the circulation of gas between the heat exchange shell 10 and the inner liner 1100.

[0082] Both the air inlet pipe 70 and the exhaust pipe 80 can be flat pipes, facilitating close fitting with the outer wall of the inner tank 1100. In some embodiments, both the air inlet pipe 70 and the exhaust pipe 80 can be connected to the side wall of the inner tank 1100, for example, the left side wall, right side wall, or rear side wall of the inner tank 1100, thereby reducing interference between the air inlet pipe 70 and the exhaust pipe 80 and other components of the washing appliance 1000, and improving the reliability of the washing appliance 1000. In some embodiments, the air inlet 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.

[0083] The intake pipe 70 and the heat exchange housing 10 can be an integrally formed structure or a separate, detachable structure. Similarly, the exhaust pipe 80 and the heat exchange housing 10 can be an integrally formed structure or a separate, detachable structure.

[0084] like Figure 2 As shown, in some embodiments, the washing appliance 1000 includes a breather 1600, and the drainage assembly 300 further includes an extension pipe 350 connecting the water pump 310 and the breather 1600. The water pump 310 is used to draw condensate from the water collection pan 14 through the drain pipe 340 and discharge the condensate to the breather 1600 through the extension pipe 350.

[0085] In this way, the condensate formed in the evaporator 20 can be fully utilized, improving the efficiency of condensate utilization. Specifically, the breather 1600 is equipped with a flow meter, which can calculate the inflow of water. All water passing through the breather 1600 passes through the flow meter. The breather 1600 can prevent backflow of water in the inner tank 1100, and it can also connect the inside and outside of the inner tank 1100, balancing the internal and external air pressure, greatly reducing manufacturing costs and the operating and maintenance costs of the washing appliance 1000, while ensuring stable and reliable operation. The breather 1600 can be fixed to the side wall of the inner tank 1100. The condensate passing through the breather 1600 can be used to wash objects inside the washing appliance 1000. It should be noted that the aforementioned breather 1600 can be purchased commercially or manufactured directly by those skilled in the art.

[0086] In some embodiments, the respirator 1600 and the water pump 310 are located on opposite sides of the bottom of the inner liner 1100, and the extension tube 350 crosses the bottom of the inner liner 1100 in a horizontal direction.

[0087] Thus, the breather 1600 and the water pump 310 are located on opposite sides of the inner tank 1100, which makes full use of the space around the inner tank 1100 and makes the structure of the washing appliance 1000 more compact. Generally, the breather 1600 is located near the front of the inner tank 1100. In this case, the extension tube 350 extends from the bottom of the inner tank 1100 to the breather 1600. This makes the total length of the extension tube 350 shorter and reduces interference between the extension tube 350 and other parts of the washing appliance 1000.

[0088] Please see Figure 2 and Figure 3 In some embodiments, the drainage assembly 300 further includes a water softener 1500, a breather 1600 connected to the water softener 1500, and a water pump 310 for draining condensate into the water softener 1500 through the extension pipe 350 and the breather 1600.

[0089] Thus, the extension tube 350 is connected to the breather 1600, which allows condensate to be discharged into the water softener 1500 without changing the existing structure of the water softener 1500, reducing the design and manufacturing costs of the washing appliance 1000. In addition, the condensate can be fully utilized by the water softener 1500.

[0090] Specifically, the water softener 1500 is an ion exchange water softener 1500 with an operation and regeneration process. It utilizes sodium-type cation exchange resin to remove calcium and magnesium ions from the water, reducing the hardness of the raw water to soften it and thus preventing scale formation from carbonates in pipes and containers. This significantly reduces investment costs while ensuring smooth production. In one embodiment, the water softener 1500 can be fixed to the side wall of the inner tank 1100. It should be noted that the aforementioned water softener 1500 can be purchased commercially or manufactured directly by those skilled in the art.

[0091] Please see Figure 3 and Figure 4 In some embodiments, the water pump 310 has an inlet 312, and the inlet 312 and the outlet 15 are located on opposite sides of the water pump 310 along its axial direction. This provides sufficient space between the inlet 312 and the outlet 15 for installing the drain pipe 340. Furthermore, this design allows the metal casing 311 of the water pump 310 to be offset from the Hall sensor 41 of the fan 40, thereby improving the detection efficiency of the Hall sensor 41.

[0092] Please see Figure 3 and Figure 9 In some embodiments, an overflow port 17 is provided on the heat exchange housing 10. The overflow port 17 is positioned higher than the drain port 15. The overflow port 17 is configured such that when condensate flows out of the overflow port 17, the condensate flowing out can be detected by the overflow detection mechanism 18.

[0093] Thus, if the drain outlet 15 becomes blocked and cannot drain the condensate in time, the condensate can flow out of the heat exchange housing 10 from the overflow outlet 17, reducing the risk of the evaporator and other components malfunctioning due to excessively high condensate levels. The overflow detection mechanism 18 monitors the liquid level of the condensate collected in the water tank. When the overflow detection mechanism 18 detects that the condensate level has reached the preset level, the washing appliance 1000 will control the alarm to sound, reminding the user or maintenance personnel to handle the fault in time to ensure the safe use of the washing appliance 1000.

[0094] The overflow detection mechanism 18 can detect condensate by means of circuit. For example, the overflow detection mechanism 18 can include a float. As the water level rises, the float triggers a micro switch to generate an electrical signal, thereby realizing the detection of condensate.

[0095] Please see Figure 3 and Figure 9 In some embodiments, the drainage component includes a guide 19 disposed on the outer wall of the heat exchange housing 10 and connected to the overflow port 17. Thus, the guide 19 can collect the condensate flowing from the overflow port 17 and direct the condensate to the overflow detection mechanism 18.

[0096] Specifically, an overflow tank 1610 can be formed on the base 1600 of the washing appliance 1000. The outer side of the heat exchange housing 10 is provided with guide members 19 that are connected to the overflow port 17. The guide members 19 can guide the condensate to the overflow tank 1610. The overflow tank 1610 is located on the base 1600 in an area away from the heat exchange housing 10 to prevent the overflowing condensate from contacting the equipment installed inside the heat exchange housing 10 again. When the liquid level of the condensate stored in the heat exchange housing 10 rises to the position of the overflow port 17, the condensate can flow through the overflow port 17 and the guide members 19 to the overflow tank 1610. Optionally, the height of the overflow port 17 can be specifically limited according to the maximum allowable liquid level of the condensate; this application does not specifically limit this.
