Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1-5 The water tank assembly 100 according to the present utility model is simple in structure, low in installation cost, and can ensure the cleanliness of the water tank assembly 100, improve the washing effect and the stability and reliability of operation, thereby improving the user experience.

[0033] like Figures 1-5 As shown, a water tank assembly 100 according to an embodiment of the present invention includes: a water tank shell 1 and a heat exchanger 3.

[0034] The water tank shell 1 has a water storage cavity 13 and a heat exchange cavity 14. The water tank shell 1 is provided with an atmospheric vent 15 that communicates with the outside. The heat exchanger 3 is installed in the heat exchange cavity 14. The heat exchanger 3 has a heat exchange channel that exchanges heat with the heat exchange cavity 14. The heat exchange channel communicates with the water storage cavity 13. The water tank shell 1 also has an inlet channel 16 and an outlet channel 17 that communicate with the heat exchange cavity 14. The inlet channel 16 and / or the outlet channel 17 are provided with a vent 173 that communicates with the atmospheric vent 15.

[0035] Among them, washing equipment can be set up as dishwashers, which are devices that automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Dishwashers can be set up as cabinet-style, countertop-style, or sink-integrated models to meet the needs of different usage scenarios. Dishwashers can integrate washing, disinfection, and drying functions, which can reduce labor intensity, improve cleanliness and hygiene, and improve work efficiency due to their short cleaning time. They can be used and washed immediately, thereby improving ease of use and user experience.

[0036] Specifically, the water tank assembly 100 is provided with a water tank shell 1, which is located on the outermost side of the water tank assembly 100 and can provide overall support for the water tank assembly 100. The water tank shell 1 can be welded together by the main shell 11 and the cover plate 12 so that the interior of the water tank shell 1 can be defined into a cavity, which can provide installation points for the internal structure of the water tank assembly 100 and ensure the operational reliability of the water tank assembly 100. A water storage cavity 13 and a heat exchange cavity 14 are formed inside the water tank assembly 100. The water storage cavity 13 can be used to store a first medium, and a second medium can circulate in the heat exchange cavity 14. The first medium can exchange heat with the second medium through the heat exchange cavity 14. When the temperature of the second medium is higher than that of the first medium, the heat can be transferred to the first medium and then stored in the water storage cavity 13.

[0037] Furthermore, the water tank assembly 100 is equipped with a heat exchanger 3, which can be disposed within the heat exchange chamber 14. A heat exchange channel is formed within the heat exchanger 3, and the end of the heat exchange channel can communicate with the water storage chamber 13, thereby allowing the first medium in the water storage chamber 13 to flow into the heat exchange channel. Since the heat exchanger 3 is disposed within the heat exchange chamber 14, the heat exchange channel can be placed within the heat exchange chamber 14. A second medium flows within the heat exchange chamber 14, thereby allowing the first medium in the heat exchange channel to exchange heat with the second medium. After heat exchange, the first medium can flow back to the water storage chamber 13 to store the heat in the water storage chamber 13.

[0038] Furthermore, the water tank shell 1 also has an inlet channel 16 and an outlet channel 17. Both the inlet channel 16 and the outlet channel 17 can be connected to the heat exchange chamber 14. That is, the outside can be supplied to the heat exchange chamber 14 through the inlet channel 16, and the second medium in the heat exchange chamber 14 can flow to the outside through the outlet channel 17. The second medium can be a high-temperature liquid, so that when the second medium flows into the heat exchange chamber 14, it can exchange heat with the low-temperature liquid in the heat exchange channel, so as to store the heat in the second medium in the outside into the water storage chamber 13, which can reduce energy consumption, improve environmental protection and energy saving, and thus improve the user experience.

[0039] It should be noted that in some embodiments, the first medium or the second medium can be the same medium, while in other embodiments, the first medium and the second medium can be different media. The first medium and the second medium can be water, refrigerant, etc., and in some cleaning application scenarios, they can also be washing media.

[0040] The inlet channel 16 and / or outlet channel 17 are provided with vents 173. Vents 173 can be provided only in the inlet channel 16, only in the outlet channel 17, or in both the inlet and outlet channels 16. In this embodiment, the vent 173 is located in the outlet channel 17. The water tank shell 1 is also provided with an atmospheric vent 15, which connects to the outside, allowing outside gas to pass through. The air vent 15 enters the water tank shell 1, and the air vent 15 is connected to the vent 173, so that the gas at the air vent 15 can enter the liquid inlet channel 16 and the liquid outlet channel 17 through the vent 173. This can eliminate the closed volume of the liquid inlet channel 16 and the liquid outlet channel 17, prevent the second medium from remaining in the liquid inlet channel 16 and the liquid outlet channel 17, thereby improving the cleanliness of the water tank assembly 100 and ensuring the operational stability and reliability of the water tank assembly 100.

[0041] According to the embodiment of the present utility model, the water tank assembly 100 is provided with a vent 173 that communicates with the atmosphere vent 15 in the liquid inlet channel 16 and / or the liquid outlet channel 17. This eliminates the closed volume of the liquid inlet channel 16 and / or the liquid outlet channel 17, preventing the medium from remaining in the liquid inlet channel 16 and / or the liquid outlet channel 17. This ensures the cleanliness of the water tank assembly 100, improves the washing effect, and enhances the stability and reliability of operation, ensuring a better user experience. Furthermore, the vent 173 has a simple structure, low installation cost, better performance, and wider applicability.

[0042] In some embodiments, the water tank shell 1 is provided with an air guide channel 18 located at the upper part of the water storage cavity 13, and the air guide channel 18 connects the atmospheric connection port 15 and the air vent 173.

[0043] Specifically, a water storage cavity 13 is provided inside the water tank shell 1. The water storage cavity 13 extends upward from the lower part of the water tank shell 1, and the first medium can be retained below the water storage cavity 13 under the action of gravity, so that the first medium can be distributed below the water tank shell 1. An air guiding channel 18 is also provided inside the water tank shell 1, such as... Figure 3 As shown, the air guide channel 18 is located at the upper part of the water storage cavity 13, which can prevent the first medium in the water storage cavity 13 from flowing into the air guide channel 18 in the event of a sealing failure between the air guide channel 18 and the water storage cavity 13, thus ensuring the independence between the air guide channel 18 and the water storage cavity 13.

[0044] Furthermore, the air guide channel 18 connects the atmospheric connection port 15 and the vent 173, that is, one end of the air guide channel 18 is connected to the atmospheric connection port 15, and the other end of the air guide channel 18 is connected to the vent 173. This allows the gas at the atmospheric connection port 15 to flow through the air guide channel 18 to the vent 173, and then through the vent 173 to flow to the liquid inlet channel 16 and / or the liquid outlet channel 17, thereby eliminating the closed volume of the liquid inlet channel 16 and / or the liquid outlet channel 17. Moreover, the air guide channel 18 is located at the top of the water storage chamber 13, which can prevent the first medium from flowing to the outside through the atmospheric connection port 15, affecting the user experience, and can also prevent the first medium from flowing to the liquid inlet channel 16 and / or the liquid outlet channel 17, thus avoiding waste and ensuring the reliability of the water tank assembly 100.

[0045] In some embodiments, a check valve 2 is provided in the air guide channel 18, which is used to unidirectionally guide the air guide channel 18 from the atmospheric connection port 15 to the air vent 173.

[0046] Specifically, a venting channel 18 is provided at the top of the water storage cavity 13. The venting channel 18 is connected between the vent 173 and the atmospheric connection port 15. A check valve 2 is provided inside the venting channel 18. The check valve 2 can be connected to the inner wall of the venting channel 18 by means of integral molding, snap-fit, or connector. The check valve 2 is provided between the venting channels 18 and can open or close the venting channel 18 so that the venting channel 18 can be unidirectionally connected from the atmospheric connection port 15 to the vent 173, or disconnect the atmospheric connection port 15 from the vent 173.

[0047] Furthermore, the vent 173 is located in the liquid outlet channel 17, allowing the second medium to flow through it. When the second medium flows through the liquid outlet channel 17, the check valve 2 can disconnect the connection between the atmospheric connection 15 and the vent 173, thereby preventing the second medium from flowing out of the water tank assembly 100 through the air guide channel 18 and the atmospheric connection 15, ensuring reliability and user experience. When the second medium stops flowing, the check valve 2 allows the air guide channel 18 to flow unidirectionally from the atmospheric connection 15 to the vent 173, allowing gas to flow through the atmospheric connection 15 and the air guide channel 18 to the vent 173, eliminating the closed volume of the liquid outlet channel 17, preventing the second medium from remaining in the liquid outlet channel 17 and generating odors, thus ensuring a good user experience.

[0048] In some embodiments, the air channel 18 is provided with a one-way through hole 185, and the check piece 2 is configured as a check piece, with one end of the check piece connected to the inner wall of the air channel 18 and the other end elastically closed in the one-way through hole 185.

[0049] Specifically, such as Figure 1 and Figure 3As shown, a one-way through hole 185 is provided in the air guide channel 18. The one-way through hole 185 is located in the middle of the air guide channel 18. One end of the one-way through hole 185 is connected to the atmospheric connection port 15 through the air guide channel 18, and the other end of the one-way through hole 185 is connected to the air vent 173 through the air guide channel 18. A check valve 2 is provided in the air guide channel 18. The check valve 2 can close the one-way through hole 185, thereby disconnecting the connection between the atmospheric connection port 15 and the air vent 173.

[0050] Furthermore, check piece 2 is configured as a check piece, such as... Figure 2 As shown, the check valve is provided with a snap-fit ​​part 21 and a stop part 22. One end of the stop part 22 is connected to the snap-fit ​​part 21. The inner wall of the guide channel is provided with a snap-fit ​​part 184. One of the snap-fit ​​part 184 and the snap-fit ​​part 21 can be set as a snap-fit ​​block and the other as a snap-fit ​​groove. That is, the snap-fit ​​part 184 can be set as a snap-fit ​​block and the snap-fit ​​part 21 can be set as a snap-fit ​​groove, or the snap-fit ​​part 184 can be set as a snap-fit ​​groove and the snap-fit ​​part 21 can be set as a snap-fit ​​block. In this embodiment, the snap-fit ​​part 184 is set as a snap-fit ​​groove and the snap-fit ​​part 21 is set as a snap-fit ​​block. The snap-fit ​​block can be snapped into the snap-fit ​​groove, so that the check valve can be connected to the inner wall of the air guide channel 18 through snap-fit.

[0051] Furthermore, the stop part 22 is constructed as a sheet-like structure. The entire check sheet or the stop part 22 is set as an elastic element. The check sheet can be connected to the side of the one-way through hole 185 away from the atmospheric connection port 15. When the air pressure at the atmospheric connection port 15 is greater than the air pressure at the vent port 173, the gas at the atmospheric connection port 15 can push open the stop part 22 to flow through the one-way through hole 185 to the vent port 173. When the air pressure at the atmospheric connection port 15 is less than the air pressure at the vent port 173, the stop part 22 is pressed against the one-way through hole 185 to make the check sheet close the one-way through hole 185, thereby cutting off the connection between the atmospheric connection port 15 and the vent port 173, preventing the leakage of the second medium, ensuring the operational reliability of the water tank assembly 100, improving the user experience, and the check part 2 has a simple structure and low installation cost, which can reduce the manufacturing cost of the water tank assembly 100.

[0052] In some embodiments, the one-way through hole 185 is located at the top of the water tank shell 1, that is, the one-way through hole 185 can be set at the highest position in the air guiding channel 18. The gas density is small and can flow to the highest point of the air guiding channel 18. Both the first medium and the second medium are liquids and can flow downwards under the action of gravity. By placing the one-way through hole 185 at the top of the water tank shell 1, the second medium can be prevented from flowing to the atmospheric connection port 15 through the one-way through hole 185, thus ensuring the reliability of the one-way through hole 185.

[0053] In some embodiments, the air guide channel 18 includes an upstream channel section 181 and a downstream channel section 182. The lower end of the upstream channel section 181 is connected to the atmospheric connection port 15, and the lower end of the downstream channel section 182 is connected to the air vent 173. The check valve 2 is located at the connection between the upper end of the upstream channel section 181 and the upper end of the downstream channel section 182.

[0054] Specifically, a gas guiding channel 18 is provided at the top of the water storage chamber 13, allowing gas to circulate within the gas guiding channel 18, and such as Figure 1 As shown, the gas guiding channel 18 is provided with an upstream channel section 181 and a downstream channel section 182. The upstream channel section 181 and the downstream channel section 182 can be connected sequentially along the gas flow direction. At least a part of the upstream channel section 181 can be configured to extend in the vertical direction, and the lower end of the upstream channel section 181 can be connected to the atmospheric connection port 15, so that the gas at the atmospheric connection port 15 can flow into the gas guiding channel 18 through the upstream channel section 181.

[0055] Furthermore, the downstream channel section 182 can also be configured to extend in the vertical direction, and the lower end of the downstream channel section 182 can be connected to the vent 173, so that the gas in the air guide channel 18 can flow through the downstream channel section 182 to the vent 173. The upper end of the upstream channel section 181 is connected to the upper end of the downstream channel section 182. The unidirectional guide hole 185 is set at the connection between the upstream channel section 181 and the downstream channel section 182, that is, the unidirectional guide hole 185 is set at the highest position of the air guide channel 18, and the check valve 2 is also installed at the connection between the upper end of the upstream channel section 181 and the upper end of the downstream channel section 182.

[0056] In this way, the gas density is relatively low, and it can flow to the highest point of the gas guiding channel 18. Since both the first and second media are liquids, they can flow downwards under the action of gravity. By installing the check valve 2 at the connection between the upper end of the upstream channel section 181 and the upper end of the downstream channel section 182, the second media can be prevented from flowing to the atmospheric connection port 15 through the one-way guide hole 185, thus ensuring the reliability of the gas guiding channel 18.

[0057] In some embodiments, at least a portion of the upstream channel segment 181 extends in a vertical direction. This means that a portion of the upstream channel segment 181 can be configured to extend in a vertical direction, or the entire upstream channel segment 181 can be configured to extend in a vertical direction. In this embodiment, a portion of the upstream channel segment 181 extends in a vertical direction, and the lower end of the upstream channel segment 181 can be connected to the atmospheric vent 15. Since the gas density is low, the gas entering the upstream channel segment 181 can flow upward along the upstream channel segment 181 and then flow into the downstream channel segment 182 through the unidirectional through-hole 185. Both the first medium and the second medium are liquids, which can flow downward under the action of gravity, thereby preventing leakage of the first medium or backflow of the second medium and ensuring reliable use.

[0058] In other embodiments, at least a portion of the downstream channel segment 182 extends in the vertical direction. This means that a portion of the downstream channel segment 182 can be configured to extend in the vertical direction, or the entire downstream channel segment 182 can be configured to extend in the vertical direction. In this embodiment, the entire downstream channel segment 182 is configured to extend in the vertical direction, and the lower end of the downstream channel segment 182 can communicate with the vent 173. The second medium is a liquid, which can flow downward under the action of gravity, thereby preventing the second medium from flowing back and ensuring the reliability of use.

[0059] In some embodiments, an air guide gap 183 is formed at the tail end of the air guide channel 18, the air guide gap 183 is connected to the air inlet 173, and the width of the air guide gap 183 is smaller than the width of the air guide channel 18 at other locations except for the air guide gap 183.

[0060] Specifically, such as Figure 1 as well as Figure 3 As shown, the front end of the air guiding channel 18 is connected to the atmospheric connection port 15, and the rear end of the air guiding channel 18 is connected to the ventilation port 173, so that the atmospheric connection port 15 can supply air to the ventilation port 173 through the air guiding channel 18. An air guiding gap 183 is formed at the rear end of the air guiding channel 18. One end of the air guiding gap 183 is connected to the main body section of the air guiding channel 18, and the other end of the air guiding gap 183 is connected to the ventilation port 173, so that the gas in the air guiding channel 18 can flow to the ventilation port 173 through the air guiding gap 183, ensuring the operational reliability of the air guiding channel 18.

[0061] Furthermore, the width of the air guide gap 183 is set to be smaller than the width of the air guide channel 18 at other locations except for the air guide gap 183. That is, the width of the air guide gap 183 is set to be smaller, and the width of the main body of the air guide channel 18 is set to be larger. The vent 173 is connected to the liquid outlet channel 17, and a second medium flows in the liquid outlet channel 17. The density of the second medium is greater than the density of the gas in the air guide channel 18. Setting the width of the air guide gap 183 to be smaller can prevent the second medium from flowing into the air guide channel through the vent 173 and can ensure the smooth flow of gas. This can prevent the second medium from flowing outside the water tank assembly 100 and ensure the user experience.

[0062] In some embodiments, the atmospheric vent 15, the air guide channel 18, and the vent 173 are all located above the heat exchange chamber 14. The second medium can flow into the heat exchange chamber 14 through the liquid inlet channel 16 and then flow out of the heat exchange chamber 14 through the liquid outlet channel 17. The heat exchanger 3 is disposed in the heat exchange chamber 14. The heat exchange channel of the heat exchanger 3 can flow through the first medium, thereby realizing the heat exchange between the first medium and the second medium and improving energy efficiency. The liquid outlet channel 17 is provided with a vent 173, and the water tank assembly 100 is provided with an atmospheric vent 15. The atmospheric vent 15 can be connected to the vent 173 through the air guide channel 18 to deliver gas into the liquid outlet channel 17, thereby eliminating the closed volume of the liquid inlet channel 16, the heat exchange chamber 14, and the liquid outlet channel 17, preventing the second medium from remaining in the liquid inlet channel 16, the heat exchange chamber 14, and the liquid outlet channel 17, and improving the cleanliness of use.

[0063] Furthermore, the atmospheric connection port 15, the air guide channel 18, and the vent 173 are all located above the heat exchange chamber 14. Since the gas has a smaller mass and the second medium has a larger mass, the second medium can flow downwards under the action of gravity. By placing the atmospheric connection port 15, the air guide channel 18, and the vent 173 above the heat exchange chamber 14, the second medium in the heat exchange chamber 14 can be prevented from flowing through the vent 173 to the air guide channel 18 and the atmospheric connection port 15, thus ensuring the reliability of use.

[0064] In some embodiments, the liquid outlet channel 17 includes an ascending section 171 and a descending section 172. The ascending section 171 is connected between the heat exchange chamber 14 and the descending section 172, and a vent 173 is provided at the connection between the ascending section 171 and the descending section 172.

[0065] Specifically, the second medium in the heat exchange chamber 14 can flow out of the water tank assembly 100 through the liquid outlet channel 17, and as... Figure 1 as well as Figure 3 As shown, the liquid outlet channel 17 is provided with an ascending section 171 and a descending section 172, which are connected. Both the ascending section 171 and the descending section 172 extend in the vertical direction. The ascending section 171 is connected between the heat exchange cavity 14 and the descending section 172, that is, the lower end of the ascending section 171 is connected to the heat exchange cavity 14 and is located above the heat exchange cavity 14. The upper end of the ascending section 171 is connected to the upper end of the descending section 172, and the lower end of the descending section 172 can be connected to the outside. This allows the second medium in the heat exchange cavity 14 to first flow upward into the ascending section 171 and then flow downward into the descending section 172.

[0066] Furthermore, a vent 173 is provided in the liquid outlet channel 17, and the vent 173 can be located at the connection between the rising section 171 and the falling section 172, that is, the vent 173 can be located at the connection between the upper end of the rising section 171 and the upper end of the falling section 172, so that the vent 173 can be located at the highest position in the liquid outlet channel 17. When the vent 173 is vented, the second medium in the rising section 171 and the falling section 172 can flow downward under the action of gravity to empty the second medium in the liquid inlet channel 16, the heat exchange chamber 14 and the liquid outlet channel 17, ensuring cleanliness. Moreover, by setting the vent 173 at the highest position, the second medium can be prevented from flowing into the air guide channel 18 through the vent 173, ensuring the reliability of the vent 173.

[0067] In actual installation, a heat exchange pump can be installed in the circulation path where the liquid inlet channel 16, heat exchange chamber 14 and liquid outlet channel 17 are located to provide flow power to the second medium.

[0068] In some embodiments, the liquid inlet channel 16 is lower than the heat exchange chamber 14 and is connected to the heat exchange chamber 14. The second medium can flow upward from the liquid inlet channel 16 under the action of a structure such as a heat exchange pump to flow into the heat exchange chamber 14 and then flow from the heat exchange chamber 14 to the liquid outlet channel 17. The liquid outlet channel 17 is connected to the upper part of the heat exchange chamber 14, so that the second medium can flow along the length of the heat exchange chamber 14, thereby prolonging the flow time of the second medium in the heat exchange chamber 14 and improving the heat exchange effect.

[0069] Furthermore, when the vent 173 is connected to the air guide channel 18, the liquid outlet channel 17, the heat exchange chamber 14, and the liquid inlet channel 16 can eliminate the closed volume, thereby allowing the second medium in the liquid outlet channel 17, the heat exchange chamber 14, and the liquid inlet channel 16 to flow downward under the action of gravity. The liquid inlet channel 16 is set to be lower than the heat exchange chamber 14, so that the second medium in the heat exchange chamber 14 can also be discharged downward through the liquid inlet channel 16, thereby emptying the second medium in the liquid outlet channel 17, the heat exchange chamber 14, and the liquid inlet channel 16, ensuring the cleanliness of the water tank assembly 100.

[0070] In some embodiments, the water tank housing 1 is further provided with an inlet 161 and an outlet 174. The inlet 161 is connected to the inlet channel 16, and the outlet 174 is connected to the outlet channel 17. Both the inlet 161 and the outlet 174 are located at the bottom of the water tank housing 1.

[0071] Specifically, such as Figures 3-4As shown, the water tank shell 1 is also provided with an inlet 161 and an outlet 174. The inlet 161 can be connected to the inlet channel 16, that is, the second medium can flow into the inlet channel 16 through the inlet 161. The outlet 174 can be connected to the outlet channel 17, that is, the second medium in the outlet channel 17 can flow out to the outside of the water tank assembly 100 through the outlet 174, so as to realize the flow of the second medium into the water tank assembly 100 and the discharge of the water tank assembly. 100, and both the inlet 161 and the outlet 174 are located at the bottom of the water tank shell 1, that is, both the inlet 161 and the outlet 174 are located below the inlet channel 16, the heat exchange chamber 14 and the outlet channel 17, so that the second medium in the inlet channel 16, the heat exchange chamber 14 and the outlet channel 17 can be discharged from the water tank assembly 100 together through the inlet 161 and the outlet 174 under the action of gravity, so as to ensure the cleanliness of the water tank assembly 100.

[0072] In addition, such as Figure 3 As shown, the water tank assembly 100 is also provided with a water storage channel 133. The water storage cavity 13 is connected to one end of the heat exchange channel, and the other end of the heat exchange channel is connected to the water storage channel 133. The water tank shell 1 is also provided with an inlet 131 and an outlet 132. The inlet 131 can be connected to the water storage channel 133, that is, the first medium can flow through the inlet 131 into the water storage channel 133, and then into the heat exchange channel, so as to flow back into the water storage cavity 13 through the heat exchange channel. The outlet 132 is connected to the water storage cavity 13. The inlet 131 and the outlet 132 can be connected to the outside of the water tank assembly 100 through a pipeline to realize the circulation path of the first medium.

[0073] In some embodiments, both the inlet 161 and the outlet 174 are open downwards, such as... Figures 3-4 As shown, the inlet 161 can communicate with the inlet channel 16, and the outlet 174 can communicate with the outlet channel 17. Both the inlet 161 and the outlet 174 are located at the bottom of the water tank shell 1, and both the inlet 161 and the outlet 174 are open downwards, so that the inlet 161 and the outlet 174 are located below the inlet channel 16, the heat exchange chamber 14 and the outlet channel 17, and extend downwards. This allows the second medium in the inlet channel 16, the heat exchange chamber 14 and the outlet channel 17 to be discharged from the water tank assembly 100 together through the inlet 161 and the outlet 174 under the action of gravity, and can avoid the second medium remaining at the inlet 161 and the outlet 174, thus ensuring the cleanliness of the water tank assembly 100.

[0074] This utility model also proposes a washing device.

[0075] The washing device according to the present invention includes a washing tank and a water tank assembly 100 as described above. The water tank assembly 100 is adapted to supply water into the washing tank, and the water outlet of the washing tank is connected to the liquid inlet channel 16.

[0076] Specifically, the washing equipment can be configured as a dishwasher, etc., and the washing equipment is equipped with a washing tank, a washing space inside the washing tank, and a washing spray arm inside the washing space. The user can place the items to be cleaned in the washing space, and the washing spray arm can spray out a first medium, such as cleaning liquid, to clean the items to be cleaned. The first medium can also be heated, thereby improving the cleaning effect on the items to be cleaned.

[0077] Furthermore, the water tank assembly 100 and the washing tank can be connected through a water supply pipeline, allowing the water tank assembly 100 to provide a first medium for cleaning items into the washing tank. The washing tank is equipped with a water outlet located at the bottom of the washing tank. The second medium, after cleaning the items, can be discharged through the water outlet. The water outlet and the heat exchange chamber 14 can be connected through the liquid inlet channel 16, allowing the second medium to flow into the heat exchange chamber 14 to exchange heat with the first medium in the heat exchange channel, thereby achieving waste heat recovery, improving the energy efficiency of the washing equipment during use, and thus improving the user experience.

[0078] In addition, a water supply pump can be installed in the water supply pipeline to transport the first medium from the water tank assembly 100 to the washing tank. A heat exchange pump can also be installed between the water outlet and the liquid inlet channel 16. The heat exchange pump can transport the second medium to the heat exchange chamber 14. When the heat exchange pump is running, the pressure in the liquid inlet channel 16 and the liquid outlet channel 17 increases, so that the check valve 2 can be tightly attached to the one-way through hole 185, thereby preventing the second medium from flowing out to the outside through the atmospheric connection port 15.

[0079] Furthermore, when the hot water pump stops working, the pressure in the inlet channel 16 and the outlet channel 17 decreases, and the gas can push open the stop part 22 of the check valve 2, and then flow into the inlet channel 16 and the outlet channel 17, so that the second medium in the inlet channel 16 and the outlet channel 17 can flow downward under the action of gravity, so as to empty the second medium in the inlet channel 16 and the outlet channel 17 and improve the cleanliness.

[0080] The second medium is the medium after the first medium is heated to clean the items. The atmospheric vent 15 can be connected to the outside or to the upper part of the washing tank, so that the gas in the washing tank can be discharged to the water tank assembly 100 through the atmospheric vent 15, and then discharged to the outside or into the liquid inlet channel 16 and the liquid outlet channel 17 through the water tank assembly 100, ensuring the reliability of the washing equipment operation.

[0081] According to the washing equipment of this utility model embodiment, by providing a vent 173 in the liquid outlet channel 17 that communicates with the atmosphere vent 15, the closed volume of the liquid outlet channel 17 can be eliminated, preventing the medium from remaining in the liquid outlet channel 17, thereby ensuring the cleanliness of the water tank assembly 100, improving the washing effect, and improving the working stability and reliability, ensuring the user experience. Moreover, the vent 173 has a simple structure, low installation cost, better performance, and wider applicability.
