DETAILED DESCRIPTION

[0037] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The utility model provides a water softener 100 and a dishwasher comprising the water softener 100. The dishwasher may further comprise a water tank assembly.

[0039] Combine Figures 1 to 3 According to an embodiment of the present invention, the water softener 100 may include a shell body 10, which is provided with a resin cavity 111, a plurality of interfaces, and a plurality of flow channels. The plurality of interfaces correspond to the plurality of flow channels, respectively, and the plurality of interfaces are used to connect to the water tank assembly. The resin cavity 111 can soften the water quality to reduce the deposition of calcium and magnesium ions in the water on the tableware and inside the dishwasher, thereby protecting the water pipes and spray system of the dishwasher. The plurality of interfaces are connected to the water tank assembly, and the plurality of interfaces can be used to connect the water tank assembly with the flow channels in the water softener 100. The plurality of interfaces can facilitate the docking of the water softener 100 with the water tank assembly, and the plurality of flow channels can facilitate the circulation of fluids, so that the water softener 100 can soften the water quality. In addition, the plurality of flow channels for the circulation of fluids are provided, so that the water softener 100 acts as a waterway plate, fully utilizing the space inside the water softener 100 and optimizing the waterway of the dishwasher.

[0040] The plurality of interfaces include a first interface 121 and a second interface 122, and the plurality of flow channels include a first flow channel 131 and a second flow channel 132. The first flow channel 131 is connected to the first interface 121, and the second flow channel 132 is connected to the second interface 122. Specifically, the first flow channel 131 can be connected to the water tank assembly through the first interface 121, and the second flow channel 132 can be connected to the water tank assembly through the second interface 122.

[0041] The water softener 100 may also include a water pump 20, which is disposed within the housing 10. The water pump 20 communicates with the first flow channel 131 and the second flow channel 132, thereby connecting the water pump 20 and the water tank assembly to form a loop. Specifically, the first flow channel 131 communicates with the water tank assembly via the first interface 121, and the second flow channel 132 communicates with the water tank assembly via the second interface 122. Under the action of the water pump 20, the first flow channel 131, the second flow channel 132, and the water tank assembly form a loop. Operation of the water pump 20 drives the water in the first flow channel 131 and the second flow channel 132 to flow, thereby achieving a circulation of water within the water tank assembly. In this case, the water softener 100 functions as a waterway plate, and the water pump 20 disposed within the housing 10 allows the water in the water tank 200 to circulate without changing the existing structure of the water tank 200.

[0042] Combine Figure 2 and Figure 13 For example, the water tank assembly may include a water tank 200 and a heat exchanger 300. A water storage space 230 may be provided in the water tank 200, and a heat exchange flow channel may be provided in the heat exchanger 300. Under the action of the water pump 20, the water storage space 230, the first flow channel 131, the second flow channel 132, and the heat exchange flow channel may form a circulating water channel. The water in the circulating water channel may exchange heat with the heat exchanger 300, thereby improving the heat exchange efficiency. That is to say, when the water pump 20 is working, the water softener 100 acts as a water channel plate, which can assist the water in the water storage space 230 to flow and exchange heat with the heat exchanger 300, thereby improving the heat exchange efficiency.

[0043] According to the water softener 100 of the embodiment of the present invention, by providing multiple interfaces and multiple flow channels corresponding to the multiple interfaces, the water softener 100 can soften the water quality while fully utilizing the space of the water softener 100 to optimize the pipes of the dishwasher. The water softener 100 is integrated with a water pump 20, a first flow channel 131, and a second flow channel 132. The water softener 100 is connected to the water tank assembly through the first interface 121 and the second interface 122, so that the water pump 20 and the water tank assembly are connected to form a loop. Without changing the structure of the existing water tank 200, water circulation in the water tank assembly is achieved, the space of the water softener 100 is fully utilized, the water path of the dishwasher is optimized, and the dishwasher's compact design is facilitated.

[0044] Combine Figure 2 and Figure 3The arrows show the flow direction of water in the water softener 100 of some embodiments of the present invention, wherein the water pump 20 may be provided with an inlet and an outlet, the first flow channel 131 may be connected to the inlet of the water pump 20, and the second flow channel 132 may be connected to the outlet of the water pump 20. When the water pump 20 is operating, water in the water tank assembly may enter the first flow channel 131 from the first interface 121, enter the inlet of the water pump 20, and leave the water pump 20 from the outlet of the water pump 20 to enter the second flow channel 132, and then enter the water tank assembly through the second interface 122. In other words, the first flow channel 131 may be an inlet flow channel, and the second flow channel 132 may be an outlet flow channel. Of course, the first flow channel 131 may be an outlet flow channel, and the second flow channel 132 may be an inlet flow channel, and this application does not impose any limitation on this.

[0045] For example, the water tank assembly may include a water tank 200 and a heat exchanger 300. The water tank 200 is connected to the heat exchanger 300. The water tank 200 has a water storage space 230 therein. The heat exchanger 300 has a first heat exchange channel therein. The first interface 121 can be connected to the water storage space 230 of the water tank 200, and the second interface 122 can be connected to the first heat exchange channel. The water storage space 230, the water pump 20, and the first heat exchange channel can be connected to form a loop. Specifically, when the water pump 20 is in operation, it can drive the water in the water storage space 230 into the first flow channel 131, and then into the first heat exchange channel through the second flow channel 132 for heat exchange, and then return to the water storage space 230. By providing the first flow channel 131, the water pump 20, and the second flow channel 132, the water in the water storage space 230 circulates, thereby achieving continuous heat exchange between the water in the water storage space 230 and the heat exchanger 300, thereby improving heat exchange efficiency.

[0046] Among them, the shell body 10 is provided with multiple interfaces and multiple flow channels corresponding to the multiple interfaces. The number of interfaces can be two, three, four, five, six, seven, eight, etc., which can be adjusted according to specific needs. This application does not limit the number of multiple interfaces.

[0047] In addition, the first flow channel 131 and the second flow channel 132 can be provided at different positions of the housing body 10. For example, the first flow channel 131 can be provided at the upper end, the middle, or the lower end of the housing body 10; and the second flow channel 132 can be provided at the upper end, the middle, or the lower end of the housing body 10. The specific positions can be adjusted as needed to fully utilize the space within the water softener 100.

[0048] Combine Figure 3 In some embodiments of the present invention, the shell body 10 includes a main body 141 and a flow channel plate 142 . The flow channel plate 142 is disposed at the upper end of the shell body 10 . Specifically, the flow channel plate 142 can be disposed above the main body 141 .

[0049] The first flow channel 131 is provided in the main body 141 and / or the flow channel plate 142, and the second flow channel 132 is provided in the main body 141 and / or the flow channel plate 142. Specifically, the first flow channel 131 can be provided in the main body 141; or, the first flow channel 131 can be provided in the flow channel plate 142; or, the first flow channel 131 can pass through the main body 141 and the first flow channel plate 131; the second flow channel 132 can be provided in the main body 141; or, the second flow channel 132 can be provided in the flow channel plate 142; or, the second flow channel 132 can pass through the main body 141 and the flow channel plate 142. The specific structure can be adjusted according to the structure of the dishwasher to fully utilize the space of the water softener 100 and make the dishwasher compact.

[0050] Combine Figure 4 In some embodiments of the present invention, the water pump 20 is disposed on the main body 141. The main body 141 can provide a mounting surface for the water pump 20 and facilitate the installation of the water pump 20 and the housing body 10. For example, a mounting seat for mounting the water pump 20 can be provided on the side wall of the main body 141. The water pump 20 can be positioned on the mounting seat to improve the structural stability of the water pump 20.

[0051] The first interface 121 and the second interface 122 are provided on the flow channel plate 142, that is, the first interface 121 and the second interface 122 are provided at the upper end portion of the shell body 10, so as to facilitate the connection and assembly of the water tank assembly of the water softener 100. The water tank assembly can be connected to the first flow channel 131 and the second flow channel 132 of the water softener 100 through the first interface 121 and the second interface 122, so as to facilitate the connection of the water pump 20 and the water tank assembly into a loop, simplify the pipe connection structure of the dishwasher, and reduce the number of water leaks.

[0052] Combine Figure 3 and Figure 4In some embodiments of the present invention, the first flow channel 131 is disposed between the main body 141 and the flow channel plate 142. The main body 141 is provided with a first connecting hole 1411. The first connecting hole 1411 extends in the vertical direction and connects the first flow channel 131 with the inlet of the water pump 20. In combination with the foregoing, the water pump 20 can be disposed in the main body 141, and the first interface 121 can be disposed on the first flow channel 131 plate. The first flow channel 131 is disposed between the main body 141 and the flow channel plate 142, thereby fully utilizing the space within the water softener 100. Specifically, water in the water tank assembly enters the first flow channel 131 from the first interface 121 and can be directed to the inlet of the water pump 20 through the first connecting hole 1411. In other words, the first connecting hole 1411 can direct the water in the first flow channel 131 to the inlet of the water pump 20. By providing the first interface 121 on the flow channel plate 142, providing the first flow channel 131 between the main body 141 and the flow channel plate 142, providing the first connecting hole 1411 on the main body 141, and arranging the water pump 20 on the main body 141, on the one hand, the installation of the water pump 20 can be facilitated, and on the other hand, the structure of the water path can be simplified, thereby fully utilizing the space of the water softener 100 and optimizing the water path of the dishwasher.

[0053] Combine Figure 4 In some embodiments of the present invention, the second flow channel 132 is disposed on the flow channel plate 142, which is provided with a second connecting hole 1421. The second connecting hole 1421 connects to the second flow channel 132. The main body 141 is provided with a third connecting hole 1412. The third connecting hole 1412 extends in the vertical direction and is vertically opposed to and connected to the second connecting hole 1421. The third connecting hole 1412 connects to the outlet of the water pump 20. Specifically, after leaving the water pump 20 at the outlet, the water first passes through the third connecting hole 1412 of the main body 141, then through the second connecting hole 1421 of the flow channel plate 142, enters the second flow channel 132, and then enters the water tank assembly through the second port 122. In other words, the second connecting hole 1421 and the third connecting hole 1412 cooperate to guide the water at the outlet of the water pump 20 to the second flow channel 132, thereby fully utilizing the space within the water softener 100 and simplifying the water path structure.

[0054] The water pump 20 is mounted on the main body 141, facilitating its installation within the housing 10. For example, the housing 10 may include a mounting base for the water pump 20, upon which the water pump 20 can be positioned. A first interface 121 and a second interface 122 may be located on the flow plate 142, facilitating connection between the water softener 100 and the water tank assembly. A first flow channel 131 may be located between the flow plate 142 and the main body 141, while a second flow channel 132 may be located on the flow plate 142. The main body 141 includes a first communication hole 1411 and a third communication hole 1412 extending in a vertical direction. The first communication hole 1411 connects to the inlet of the water pump 20, while the third communication hole 1412 connects to the outlet of the water pump 20. The flow plate 142 also includes a second communication hole 1421, which connects the second flow channel 132 and the third communication hole 1412. This optimizes the flow channel structure, fully utilizing the space within the water softener 100 and improving space efficiency.

[0055] The first flow channel 131 is provided between the flow channel plate 142 and the main body 141. A flow channel groove may be provided on the side of the flow channel plate 142 facing the main body 141, as well as on the side of the main body 141 facing the flow channel plate 142, so that the first flow channel 131 is defined between the flow channel plate 142 and the main body 141. The flow channel plate 142 is provided with a through hole connecting the first port 121 and the first flow channel 131, so that water from the first port 121 can enter the first flow channel 131. Furthermore, the flow channel plate 142 may include a plate body and a cover, which may be provided over the plate body. Multiple flow channels may be formed between the plate body and the cover to maintain a flow environment for the multiple flow channels.

[0056] The water softener 10 of the present embodiment integrates a water pump 20, a first flow channel 131, and a second flow channel 132, capable of assisting the flow and heat exchange between the water in the water storage space 230 of the water tank 200 and the heat exchanger 300. For example, the heat exchanger 300 may be provided with a first heat exchange channel and a second heat exchange channel for heat exchange. The water storage space 230, the water pump 20, and the first heat exchange channel may form a loop, and the second heat exchange channel may be connected to wash water with residual heat. It should be noted that the wash water in the present embodiment refers to the waste water with residual heat left after the dishwasher completes the wash cycle. In other words, the water in the first heat exchange channel can absorb heat from the wash water with residual heat to raise the initial temperature of the water in the water storage space 230, thereby recovering and reusing the heat from the wash water and reducing the energy consumption required for subsequent water heating.

[0057] Typically, dishwashers fill the water tank multiple times during a wash cycle, and some wash cycles require water heating to improve the dishwasher's performance. After the wash cycle is complete, the wash water is discharged directly into the drain. Understandably, the wash water is usually warmer than room temperature when it's discharged, and contains residual heat. Directly draining the water into the drain wastes energy.

[0058] Among them, the heat exchanger 300 is connected to the washing water with residual heat, and the heat exchanger 300 can be directly connected to the washing chamber. For example, it can be connected through a pipeline to connect the washing water in the washing chamber to the heat exchanger 300 to exchange heat with the water in the water storage space 230; or, it can be connected to the washing chamber through the water softener 100, that is, the water softener 100 is provided with an interface connecting the washing chamber and the water tank assembly, and a flow channel can be provided inside the water softener to facilitate the connection of the washing water with residual heat in the washing chamber to the heat exchanger 300.

[0059] Combine Figure 9 In some embodiments of the present invention, the housing body 10 may further include a third port 123, a fourth port 124, a wash water inlet 151, and a wash water outlet 152. The third port 123 connects to the wash water inlet 151, and the fourth port 124 connects to the wash water outlet 152. In other words, the heat exchanger 300 and the wash chamber can be connected via the water softener 100, allowing the water softener 100 to serve as an auxiliary waterway component for wash water heat exchange. This structural design of the water softener 100 allows for energy recovery from the wash water without changing the existing dishwasher layout, eliminating the need for additional piping, support, and fixing structures for the pipes, reducing leaks, and improving the reliability of the dishwasher.

[0060] The shell body 10 may also be provided with a third flow channel 133 and a fourth flow channel 134, wherein the third flow channel 133 connects the washing water inlet 151 and the third interface 123, and the fourth flow channel 134 connects the fourth interface 124 and the washing water outlet 152. The washing water inlet 151 is used to connect washing water with waste heat, the third interface 123 is used to input washing water to the heat exchanger 300, the fourth interface 124 is used for washing water to flow back from the heat exchanger 300, and the washing water outlet 152 is used to discharge washing water.

[0061] Specifically, the water softener 100 of the present embodiment can be connected to the dishwasher's washing chamber and heat exchanger 300, respectively. For example, the third port 123 and the fourth port 124 can be connected to the heat exchanger 300, and the wash water inlet 151 can be connected to a water cup in the washing chamber. Water with residual heat can be directed through the water softener 100 to the heat exchanger 300. After heat exchange, it flows back through the water softener 100 and is discharged into the sewer. By directing the residual heat water to the heat exchanger 300 to exchange heat with the water in the water storage space 230, the initial temperature of the water in the water storage space 230 is raised, the heat of the wash water can be recovered and reused, and the energy consumption required for subsequent water heating is reduced.

[0062] For example, in combination Figure 9, the arrow shows the flow direction of washing water. The washing water inlet 151 can be connected to the water cup of the washing chamber. The washing water containing residual heat enters the third flow channel 133 from the washing water inlet 151 and enters the heat exchanger 300 through the third interface 123. The heat exchanger 300 can be provided with a first heat exchange flow channel and a second heat exchange flow channel for heat exchange. Combined with the above, the first heat exchange flow channel can be connected to the water pump 20 and the water in the water storage space 230 to form a loop, and the second heat exchange flow channel can be connected to the third interface 123 and the fourth interface 124. That is to say, the washing water containing residual heat enters the second heat exchange flow channel from the third interface 123 and exchanges heat with the water in the first heat exchange flow channel, thereby preheating the water in the water tank 200; after completing the heat exchange, the washing water flows back to the water softener 100 from the fourth interface 124, and is discharged to the sewer from the washing water outlet 152 through the fourth flow channel 134.

[0063] The wash water inlet 151 and the wash water outlet 152 can both be connected to the wash chamber. For example, a wash pump can be installed in the wash chamber, driving the wash water from the water softener 100 into the heat exchanger 300. After heat exchange, the water can flow back into the wash chamber through the wash water outlet 152 and be discharged into the sewer. The wash water inlet 151 and the wash water outlet 152 can be located on the same sidewall of the water softener 100, reducing the number of pipes and facilitating installation of the water softener 100.

[0064] By providing a wash water inlet 151 and a wash water outlet 152 on the water softener 100, it is convenient for the water softener 100 to receive and discharge wash water. The water softener 100 is also provided with a first interface 121, a second interface 122, a third interface 123, and a fourth interface 124, so that the water softener 100 can be connected to the water tank assembly. The water softener 100 is also provided with a water pump 20, which forms a circuit with the water in the water storage space 230. The water softener 100 is also provided with a flow channel for the inlet and outlet of wash water, so that the water softener 100 serves as an auxiliary water channel component for heat exchange of wash water. Without changing the structural layout of the existing dishwasher, the structural design of the water softener 100 can achieve energy recovery of wash water, avoid the need for additional pipelines and support and fixing structures for heat exchange of wash water, reduce water leakage points, and improve the reliability of the dishwasher.

[0065] Combine Figure 1 In some embodiments of the present invention, the multiple interfaces include a fifth interface 125, and the housing body 10 is further provided with a water outlet 153 connected to the washing chamber. The water softener 100 also includes a first reversing valve 30, which is disposed on the housing body 10 and connects the fifth interface 125, the resin chamber 111, and the water outlet 153. The first reversing valve 30 has a first operating mode and a second operating mode. In the first operating mode, the resin chamber 111 is connected to the water outlet 153 to allow water to flow into the washing chamber. In the second operating mode, the resin chamber 111 is connected to the fifth interface 125 to allow water to flow into the water tank assembly.

[0066] Specifically, resin chamber 111 softens water, water outlet 153 connects to the dishwasher's wash chamber, and fifth port 125 connects to the water tank assembly. In the first operating mode of first reversing valve 30, resin chamber 111 communicates with water outlet 153, allowing water softened by resin chamber 111 to enter the wash chamber directly. In the second operating mode of reversing valve 30, resin chamber 111 communicates with fifth port 125, connecting the resin chamber 111 to the water tank assembly, allowing softened water to enter the water tank assembly. Once softened water enters the water tank assembly, it can be stored there to provide a stable water flow to the wash chamber; alternatively, the softened water can be preheated to raise its initial temperature.

[0067] For example, a dishwasher can be configured with multiple wash programs. In wash programs such as pre-rinse and quick wash, water softened in the resin chamber 111 can be directly introduced into the wash chamber to reduce the deposition of calcium and magnesium ions in the water on dishes and within the dishwasher, protecting the dishwasher's water pipes and spray system and improving water efficiency. In some wash programs, water softened in the resin chamber 111 can be first introduced into a water tank assembly, which stores the softened water to provide a stable water flow to the wash chamber. In some wash programs, hot water is required for washing, and water softened in the resin chamber 111 can be first introduced into the water tank assembly. The water tank assembly can be equipped with a heat exchanger 300 to preheat the softened water to increase its initial temperature. Therefore, the softened water flows in different directions in different wash programs. By integrating a first reversing valve 30 into the water softener 100, water flow switching can be achieved within the water softener 100 to meet the requirements of various wash programs.

[0068] The first reversing valve 30 is capable of switching the direction of water flow. For example, the first reversing valve 30 may be a two-position, three-way valve that controls the water softened by the resin chamber 111 to selectively flow to the water outlet 153 or the fifth interface 125. Alternatively, the first reversing valve 30 may be a solenoid valve that controls the opening or closing of the passage between the resin chamber 111 and the water outlet 153, and the opening or closing of the passage between the resin chamber 111 and the fifth interface 125, by turning power on or off. Of course, the first reversing valve 30 may also be configured as other types of valves, and this application does not limit the type of the first reversing valve 30.

[0069] Furthermore, the first reversing valve 30 may be directly connected to the resin chamber 111, the water outlet 153, and the fifth port 125, or may be connected via flow channels. For example, the housing body 10 may be provided with multiple flow channels, which may be located at different locations within the housing body 10, such as at the top, bottom, or middle of the housing body 10, to facilitate switching of water channels within the water softener 100 and improve space utilization within the water softener 100.

[0070] Exemplarily, a fifth flow channel 135 , a sixth flow channel 136 and a seventh flow channel 137 are provided in the shell body 10 .

[0071] Combine Figure 10 The fifth flow channel 135 is connected to the first reversing valve 30 and the water outlet 153, combined with Figure 6 The sixth flow channel 136 connects the resin chamber 111 and the first reversing valve 30, combined with Figure 7 The seventh flow channel 137 connects to the first reversing valve 30 and the fifth port 125. Multiple flow channels are connected to the first reversing valve 30, facilitating control of the water flow direction via the first reversing valve 30. Furthermore, the multiple flow channels are integrated into the housing 10, facilitating switching of water paths while the water flows within the water softener 100. This reduces the number of pipe connections between the washing chamber and the water tank assembly, reduces leaks, and saves space in the dishwasher's installation.

[0072] Combine Figure 8 Furthermore, the first reversing valve 30 may have a first port 31, a second port 32, and a third port 33. The first port 31 connects to the fifth flow channel 135, the second port 32 connects to the sixth flow channel 136, and the third port 33 connects to the seventh flow channel 137. In a first operating mode, the first port 31 and the second port 32 connect, allowing the fifth flow channel 135 to communicate with the sixth flow channel 136, allowing water softened by the resin chamber 111 to flow to the water outlet 153. In a second operating mode, the second port 32 and the third port 33 connect, allowing the sixth flow channel 136 to communicate with the seventh flow channel 137, allowing the softened water by the resin chamber 111 to flow to the fifth port 125, and then enter the water tank assembly for storage or heat exchange. The provision of three ports facilitates control of the water flow direction through the first reversing valve 30, simplifying the control method for water path switching.

[0073] Among them, the first port 31, the second port 32, and the third port 33 can be arranged in the up and down direction, which is convenient for the installation of the first reversing valve 30 and the shell body 10, and facilitates the compact arrangement of multiple flow channels, making the structure of the water softener 100 compact and improving space utilization.

[0074] For example, the first port 31 , the second port 32 , and the third port 33 may be arranged in sequence along the up-down direction, and the first port 31 , the second port 32 , and the third port 33 may face the same side to optimize the flow path in the water softener 100 , facilitate the compact arrangement of multiple flow paths, and improve the space utilization of the water softener 100 .

[0075] Combine Figure 6 、 Figure 7 and Figure 11 In some embodiments of the present invention, the multiple interfaces include a sixth interface 126. The water tank assembly includes a drain port 211 and a drain valve 212 for opening and closing the drain port 211. The drain port 211 is connected to the sixth interface 126. When the drain valve 212 is open, the first reversing valve 30 is in the first operating mode. In other words, the passage between the drain port 211 and the sixth interface 126 can be opened and closed by the drain valve 212. When the drain valve 212 is open, water can flow through the drain port 211 to the water softener 100, and the water is then directed to the washing chamber by the water softener 100.

[0076] Combine Figure 6 Specifically, the housing body 10 may further include an eighth flow channel 138, which connects the sixth port 126 and the sixth flow channel 136. Softened water stored in the water tank assembly can be directed to the washing chamber through the sixth port 126. When the softened water in the water tank assembly is needed, the drain valve 212 is opened, and the softened water flows from the sixth port 126 into the eighth flow channel 138 and then into the sixth flow channel 136. At this time, the second reversing valve 40 may be in the first operating mode, with the first port 31 and the second port 32 connected. The softened water entering the sixth flow channel 136 enters the washing chamber through the water outlet 153.

[0077] Among them, when the drain valve 212 is opened, the first reversing valve 30 is in the first working mode. For example, the control system can control the linkage between the drain valve 212 and the first reversing valve 30. When the softened water in the water tank assembly is needed, the drain valve 212 is opened, and at the same time, the first port 31 and the second port 32 of the first reversing valve 30 are controlled to be connected. The water in the fifth flow channel 135 can flow to the water outlet 153 and enter the washing chamber.

[0078] In some embodiments of the present invention, the shell body 10 further includes a salt chamber 112 and a water inlet 154, the water inlet 154 is connected to a tap water source, and the water softener 100 further includes a second reversing valve 40, the second reversing valve 40 connects the water inlet 154, the resin chamber 111 and the salt chamber 112, and when the second reversing valve 40 connects the water inlet 154 and the salt chamber 112, the salt chamber 112 connects the resin chamber 111, and the first reversing valve 30 is set to the first mode.

[0079] Specifically, the water inlet 154 can be connected to a tap water source, the resin chamber 111 can be filled with resin, and the salt chamber 112 can be filled with softening salt. When the resin in the resin chamber 111 becomes saturated with calcium, magnesium, and other ions, the softening capacity of the resin chamber 111 decreases, and the salt solution in the salt chamber 112 is required to regenerate the resin. The second reversing valve 40 can control whether the tap water entering the water inlet 154 enters the softening chamber for softening, or first enters the salt chamber 112 to form a brine solution and then enter the resin chamber 111. The sodium ions in the brine solution will exchange with the calcium and magnesium ions adsorbed on the resin, thereby restoring the ion exchange capacity of the resin, regenerating the resin, protecting the dishwasher and tableware, and extending the service life of the dishwasher.

[0080] The second reversing valve 40 controls the connection between the water inlet 154 and the resin chamber 111, while disconnecting the resin chamber 111 from the salt chamber 112. After being softened by the resin chamber 111, the tap water entering the water inlet 154 is controlled by the first reversing valve 30 to enter the water tank 200 or the washing chamber. When the softening capacity of the resin chamber 111 decreases, the second reversing valve 40 controls the connection between the water inlet 154 and the salt chamber 112, and vice versa. The tap water entering the water inlet 154 first enters the salt chamber 112 and then the resin chamber 111. The softened water is then controlled by the first reversing valve 30 to enter the water tank 200 or the washing chamber. By providing the first reversing valve 30 and the second reversing valve 40 in cooperation, the water circuit is switched. The first reversing valve 30 and the second reversing valve 40 are both integrated into the water softener 100, so that the water flow in the water softener 100 can complete the switching of the water circuit, simplify the pipe connection of the dishwasher, and improve the space utilization of the dishwasher.

[0081] When the second reversing valve 40 connects the water inlet 154 and the salt chamber 112, the salt chamber 112 connects to the resin chamber 111, and the first reversing valve 30 is set to the first operating mode. Specifically, when the softening capacity of the resin chamber 111 decreases, the second reversing valve 40 controls the connection between the water inlet 154 and the salt chamber 112, and vice versa. The tap water entering the water inlet 154 first enters the salt chamber 112 and then the resin chamber 111. At this point, the resin chamber 111 is connected to the water outlet 153 to facilitate the discharge of waste brine.

[0082] For example, the control system can control the linkage of the first reversing valve 30 and the second reversing valve 40. When the resin needs to be regenerated, the second reversing valve 40 connects the water inlet 154 and the salt chamber 112, and the salt chamber 112 is connected to the resin chamber 111. At the same time, the first port 31 and the second port 32 of the first reversing valve 30 are controlled to be connected to facilitate the discharge of waste brine.

[0083] Combine Figure 10In some embodiments of the present invention, the shell body 10 has a first side surface 161 and a second side surface 162 arranged opposite to each other, the first reversing valve 30 is provided on the first side surface 161, and the second reversing valve 40 is provided on the second side surface 162. The first reversing valve 30 and the second reversing valve 40 are arranged opposite to each other on the sides of the shell body 10. On the one hand, it can facilitate the installation of the first reversing valve 30 and the second reversing valve 40, and optimize the flow path of the water softener 100, shorten the length of the flow path, and facilitate the compact design of the water softener 100.

[0084] In addition, the shell body 10 also has a third side surface 163 connecting the first side surface 161 and the second side surface 162. The water inlet 154 and the water outlet 153 are arranged on the third side surface 163, which can shorten the length of the flow channel, fully utilize the space inside the water softener 100, and facilitate the compact design of the water softener 100.

[0085] Combine Figure 1 and Figure 12 In some embodiments of the present invention, the plurality of interfaces further include a seventh interface 127 and an eighth interface 128 . The seventh interface 127 is connected to the water inlet 154 , and the eighth interface 128 is connected to the second reversing valve 40 . The water tank assembly is provided with a water inlet channel 221 , the inlet of which is connected to the seventh interface 127 , and the outlet of which is connected to the eighth interface 128 . A one-way valve 222 is provided in the water inlet channel 221 . Specifically, the one-way valve 222 is configured to control the one-way conduction of the water inlet channel 221 from the inlet to the outlet. The tap water entering the water inlet 154 enters the water inlet channel 221 of the water tank assembly through the seventh interface 127, then returns to the shell body 10 from the eighth interface 128, and is controlled by the second reversing valve 40 to enter the resin chamber 111 or the salt chamber 112. By setting the seventh interface 127 and the eighth interface 128 to connect the water tank assembly, and integrating a one-way valve 222 in the water tank assembly, the water in the water inlet channel 221 is controlled to be unidirectional from the inlet to the outlet, which can prevent the tap water from flowing back when entering the water softener 100.

[0086] Combine Figures 11 to 13The present invention also provides a dishwasher, comprising: a water tank assembly and the aforementioned water softener 100, wherein the water tank assembly includes a water tank 200 and a heat exchanger 300. The water tank 200 has a water storage space 230. The heat exchanger 300 is connected to the water tank 200 and has a first heat exchange channel connected to the water storage space 230. The water pump 20, the heat exchanger 300, and the first heat exchange channel are connected to form a heat exchange loop. Specifically, the first interface 121 can be connected to the water storage space 230 of the water tank 200, and the second interface 122 can be connected to the first heat exchange channel. The water storage space 230, the water pump 20, and the first heat exchange channel can be connected to form a loop. When the water pump 20 is in operation, it can drive water in the water storage space 230 into the first flow channel 131, and then enter the first heat exchange channel through the second flow channel 132 for heat exchange, and then return to the water storage space 230. This allows the water in the water storage space 230 to continuously exchange heat with the heat exchanger 300, thereby improving heat exchange efficiency.

[0087] The water tank 200 and the heat exchanger 300 may be separate structures; or, the water tank 200 may be disposed inside the water tank 200 .

[0088] Combine Figure 13 In some embodiments of the present invention, the heat exchanger 300 is disposed in the water tank 200 , which fully utilizes the space in the water tank 200 and improves the structural stability of the heat exchanger 300 .

[0089] The water storage space 230 is provided with a first opening 231, a second opening 232, and a third opening 233. The first opening 231 and the second opening 232 respectively connect to the two ends of the first heat exchange channel. The second port 122 connects to the second opening 232, and the first port 121 connects to the third opening 233. Specifically, water in the water storage space 230 can enter the first flow channel 131 of the water softener 100 through the third opening 233, then flow through the water pump 20 into the second flow channel 132, and then enter the first heat exchange channel through the second opening 232 for heat exchange. After heat exchange in the heat exchanger 300, the water can return to the water storage space 230 through the first opening 231. By integrating the heat exchanger 300 into the water tank 200, the heat exchange flow path of the heat exchanger 300 is simplified.

[0090] In some embodiments of the present invention, the first heat exchange channel is arranged in the up and down direction, the first opening 231 is connected to the upper end of the first heat exchange channel, the second opening 232 is connected to the lower end of the first heat exchange channel, and the second opening 232 and the third opening 233 are provided at the lower end of the water tank 200. The second opening 232 and the third opening 233 can facilitate the connection of the water tank 200 to the water softener 100, and cooperate with the third opening 233 to optimize the heat exchange flow path and shorten the length of the flow channel.

[0091] In some embodiments of the present invention, the dishwasher further comprises: a water cup and a washing pump, wherein the inlet of the washing pump is connected to the water cup; wherein the heat exchanger 300 further comprises a second heat exchange channel, wherein the second heat exchange channel is connected to the outlet of the washing pump. Specifically, the second heat exchange channel can be connected to washing water containing residual heat. In combination with the above, the residual heat of the washing water can be used to exchange heat with the water in the water storage space 230, thereby raising the initial temperature of the water in the water storage space 230, reducing the energy consumption required for subsequent water heating, and realizing the recovery and reuse of the heat of the washing water. Exemplarily, the first heat exchange channel is a cold water channel, and the second heat exchange channel is a hot water channel, and the first heat exchange channel and the second heat exchange channel cooperate in heat exchange.

[0092] Specifically, a wash pump can be used to drive wash water from the water cup into the heat exchanger 300. After heat exchange, the wash water is discharged into the sewer. For example, the inlet of the second heat exchange channel can be connected to the outlet of the wash pump, and the outlet of the second heat exchange channel can be connected to the water cup. In other words, after heat exchange, the wash water can flow back into the water cup and be discharged into the sewer. Alternatively, the outlet of the second heat exchange channel can be connected to a pipeline to discharge into the sewer. Driven by the wash pump, the wash water with residual heat enters the second heat exchange channel and undergoes heat exchange with the water in the first heat exchange channel. After heat exchange, the wash water is discharged into the sewer.

[0093] Furthermore, a fourth opening 234 and a fifth opening 235 are provided at the lower end of the water tank 200, respectively connecting the two ends of the second heat exchange channel. The flow channel provided on the water tank 200 directs the wash water to the heat exchanger 300, facilitating a compact design of the water tank assembly.

[0094] Combine Figure 9 and Figure 12 In some embodiments of the present invention, the water softener 100 is further provided with a third interface 123, a fourth interface 124, a washing water inlet 151 and a washing water outlet 152. The third interface 123 is connected to the washing water inlet 151, the fourth interface 124 is connected to the washing water outlet 152, the third interface 123 is connected to the fourth opening 234, and the fourth interface 124 is connected to the fifth opening 235, wherein the washing water outlet 152 is connected to the inlet of the water cup, and the washing water inlet 151 is connected to the outlet of the washing pump. For example, the water softener 100 can be connected to the washing chamber and the water tank 200 respectively. By providing an interface and a flow channel on the water softener 100, the washing water can be directed to the heat exchanger 300 through the water softener 100, so that the water softener 100 can serve as an auxiliary water channel component for washing water heat exchange. The existing structural layout of the dishwasher can be maintained. By structurally designing the water softener 100, energy recovery of the washing water can be achieved, and the need for additional pipelines, as well as support and fixing structures for the pipelines, for washing water heat exchange is avoided, thereby reducing leakage points and improving the reliability of the dishwasher.

[0095] The following is combined with Figure 9 and Figure 12 , detailed description of some embodiments of the present invention, the specific flow path of the washing water during heat exchange: driven by the washing pump, the washing water containing residual heat enters the water softener 100 from the water cup, specifically, enters the third interface 123 from the washing water inlet 151, and then enters the second heat exchange channel through the fourth opening 234, and exchanges heat with the water in the first heat exchange channel. After the heat exchange is completed, the washing water returns to the water softener 100 from the fifth opening 235, specifically, enters the water softener 100 from the fourth interface 124, and returns to the water cup through the washing water outlet 152, and is discharged from the water cup to the sewer.

[0096] Combine Figures 1 to 12 In some specific embodiments of the present invention, the water softener 100 is integrated with a water pump 20 to assist in water circulation in the water tank assembly. This facilitates installation of the water pump 20 and fully utilizes the space of the water softener 100. The water softener 100 also includes a first reversing valve 30 to facilitate controlling the flow direction of softened water according to different washing programs, so that the water flow completes the water path switching in the water softener 100, simplifying the water path design of the dishwasher. The water softener 100 also includes a second reversing valve 40. The second reversing valve 40 can control whether the tap water entering the water inlet 154 enters the resin chamber 111 for softening, or first enters the salt chamber 112 to form a brine solution and then enter the resin chamber 111. When the second reversing valve 40 connects the water inlet 154 and the salt chamber 112, the salt chamber 112 connects to the resin chamber 111, and the first reversing valve 30 connects the resin chamber 111 and the water outlet 153, facilitating the discharge of brine. The first reversing valve 30 and the second reversing valve 40 cooperate to switch the water flow within the water softener 100, simplifying the pipe connections of the dishwasher and improving the space utilization of the dishwasher. In addition, a drain valve 212 is provided on the water tank 200. The drain valve 212 cooperates with the first reversing valve 30 to facilitate the water in the water tank 200 to enter the washing chamber through the water softener 100.

[0097] Combine Figures 1 to 12In some specific embodiments of the present invention, the water softener 100 includes a first interface 121, a second interface 122, a third interface 123, a fourth interface 124, a fifth interface 125, a sixth interface 126, a seventh interface 127, and an eighth interface 128 for connecting to the water tank assembly. The first interface 121 and the second interface 122 cooperate to circulate water in the water tank 200. The third interface 123 and the fourth interface 124 cooperate with the heat exchanger 300 to recover waste heat from the wash water. The fifth interface 125 and the sixth interface 126 allow water to flow from the resin chamber 111 to the water tank 200 and from the water tank 200 to the wash chamber. The seventh interface 127 and the eighth interface 128 cooperate to prevent siphonage of tap water. The eight interfaces can be located on the same side of the water softener 100 and arranged side by side to facilitate docking between the water softener 100 and the water tank assembly. In addition, the first interface 121, the second interface 122, the third interface 123 and the fourth interface 124 can be arranged on the same side to cooperate in realizing the waste heat recovery of the washing water, and the fifth interface 125, the sixth interface 126, the seventh interface 127 and the eighth interface 128 can be arranged on the same side and adjacent to the resin cavity 111 to optimize the arrangement of the flow channel.

[0098] In some specific embodiments of the present invention, the water softener 100 may further include a washing water inlet 151, a washing water outlet 152, and a water outlet 153 connected to the washing chamber, and the washing water inlet 151, the washing water outlet 152, and the water outlet 153 may be arranged on the same side of the water softener 100 to optimize the arrangement of the flow channel and facilitate the docking of the water softener 100 with the washing chamber.

[0099] The water softener 100 not only softens the water, but also serves as an intermediate component connecting the washing chamber and the water tank assembly. The water tank assembly can store water and recover the energy of the washing water. During heat exchange, the cold water in the water tank 200 is driven to circulate through the water pump 20 integrated in the water softener 100, flowing and exchanging heat. The washing water with residual heat in the washing chamber is driven by the washing pump and passes through the water channel integrated in the water softener 100 to enter the heat exchanger 300 for heat exchange. This avoids the need to add pipelines, as well as support and fixing structures for the pipelines for heat exchange of the washing water, reduces water leakage points, and improves the reliability of the dishwasher.
