When the water discharge valve 230 is opened, water can be passed through the water discharge port 221 to the water softener 100, and the water is guided to the washing chamber through the water softener 100. Among them, when the water discharge valve 230 is opened, the first reversing valve 20 is in the first working mode.

[0053] Specifically, the second interface 132 can be connected to the water tank 200. The softened water stored in the water tank 200 can be guided to the washing chamber through the second interface 132. When the softened water in the water tank 200 needs to be used, the water discharge valve 230 is opened, and the softened water enters the fourth flow channel 144 from the second interface 132 and then flows to the second flow channel 142. At this time, the first reversing valve 20 can be in the first working mode, and the first port 21 and the second port 22 are communicated. The softened water entering the second flow channel 142 enters the washing chamber from the washing chamber interface 121.

[0054] Among them, when the water discharge valve 230 is opened, the first reversing valve 20 is in the first working mode. Exemplarily, the linkage of the water discharge valve 230 and the first reversing valve 20 can be controlled by the control system. When the softened water in the water tank 200 needs to be used, the water discharge valve 230 is opened, and at the same time, the first port 21 and the second port 22 of the first reversing valve 20 are communicated. The water in the second flow channel 142 can flow to the washing chamber interface 121 and enter the washing chamber. In addition, the fourth flow channel 144 can be provided in the main body portion 151. Combining the foregoing, the first flow channel 141 and the second flow channel 142 are also provided in the main body portion 151. That is to say, the water in the water tank 200 enters the washing chamber through the main body portion 151 of the water softener 100, optimizing the flow channels in the water softener 100, and thereby improving the efficiency of the water in the water tank 200 entering the washing chamber.

[0055] In some embodiments of the present utility model, the washing chamber interface 121 can be configured to connect to the water cup of the dishwasher. That is to say, the water softener 100 is connected to the water cup of the dishwasher to optimize the pipeline of the dishwasher. Combining the foregoing, the water softened by the resin chamber 111 can be directly connected to the water cup through the washing chamber interface 121, or first enter the water tank 200 for pre-storage, and then enter the water cup through the water softener 100, optimizing the pipeline structure of the dishwasher, reducing the pipeline connection between the water cup and the water tank 200, reducing the leakage points, and saving the installation space of the dishwasher. Exemplarily, the washing chamber interface 121 and the water cup can be connected through a pipeline. Combining Figure 1 and Figure 2 , in some embodiments of the present utility model, an inlet 1111 is provided at the lower end of the resin chamber 111 and an outlet 1112 is provided at the upper end of the resin chamber 111 in the up-down direction. The outlet 1112 of the resin chamber 111 is connected to the first reversing valve 20 through the second flow channel 142.

[0056] Specifically, the tap water source can enter the resin chamber 111 from below the resin chamber 111. After being softened by the resin, it can enter the first reversing valve 20 through the second flow channel 142 from above the resin chamber 111, and the water path is switched by the first reversing valve 20, and it can selectively enter the washing chamber or enter the water tank 200. Among them, the outlet 1112 is provided above the resin chamber 111, which is convenient for the tap water to fully contact the resin, improving the softening efficiency and effect of the water.

[0057] Furthermore, the first reversing valve 20 is connected to the first side wall 113 of the housing main body 10, which is convenient for the installation of the first reversing valve 20 and the housing main body 10, and is also convenient for switching the water path of the softened water through the first reversing valve 20. The washing chamber interface 121 is connected to the second side wall 114 of the housing main body 10. The first side wall 113 and the second side wall 114 are adjacent. Specifically, the washing chamber interface 121 can be used to connect to the washing chamber. When the first reversing valve 20 connects the first flow channel 141 and the second flow channel 142, the water softened by the resin chamber 111 can enter the washing chamber. The adjacent first side wall 113 and the second side wall 114 can shorten the length of the flow channel, make full use of the space inside the water softener 100, and improve the space utilization rate of the water softener 100.

[0058] In some embodiments of the present utility model, the housing main body 10 is further provided with a salt chamber 112 and a water inlet interface 122. The water softener 100 further includes: a second reversing valve 30, and the second reversing valve 30 connects the water inlet interface 122, the resin chamber 111 and the salt chamber 112. Exemplarily, the second reversing valve 30 has a third working mode and a fourth working mode. In the third working mode, the water inlet interface 122 is connected to the resin chamber 111, and the salt chamber 112 is disconnected from the resin chamber 111. In the fourth working mode, the water inlet interface 122 is connected to the salt chamber 112, and the salt chamber 112 is connected to the resin chamber 111.

[0059] Specifically, the water inlet interface 122 can be connected to a tap water source. Resin can be contained in the resin chamber 111, and softening salt can be added to the brine chamber. When the calcium, magnesium and other ions adsorbed by the resin in the resin chamber 111 are saturated, the softening capacity of the resin chamber 111 decreases, and the salt solution in the salt chamber 112 is needed to regenerate the resin. The second reversing valve 30 can control the tap water source entering from the water inlet interface 122 to enter the soft water chamber for softening, or first enter 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 to regenerate the resin, protect the dishwasher and tableware, and at the same time extend the service life of the dishwasher.

[0060] Among them, the second reversing valve 30 can control the water inlet interface 122 to communicate with the resin chamber 111, and the resin chamber 111 is disconnected from the salt chamber 112. The tap water source entering from the water inlet interface 122 is softened by passing through the resin chamber 111 and then controlled by the first reversing valve 20 to enter the water tank 200 or enter the washing chamber. When the softening capacity of the resin chamber 111 decreases, the second reversing valve 30 can control the water inlet interface 122 to communicate with the salt chamber 112, and the salt chamber 112 communicates with the resin chamber 111. The tap water source entering from the water inlet interface 122 first enters the salt chamber 112 and then enters the resin chamber 111. The softened water is controlled by the first reversing valve 20 to enter the water tank 200 or enter the washing chamber. By setting the first reversing valve 20 and the second reversing valve 30 to cooperate, the switching of the water circuit is realized, and both the first reversing valve 20 and the second reversing valve 30 are integrated in the water softener 100, so as to facilitate the switching of the water circuit within the water softener 100, simplify the pipeline connection of the dishwasher, and improve the space utilization rate of the dishwasher.

[0061] Optionally, in combination with Figure 2 , an eighth flow channel 148 is further provided in the housing main body 10, and the eighth flow channel 148 communicates the water inlet interface 122 and the water inlet 1111 of the resin chamber 111. Among them, the eighth flow channel 148 can be arranged on the second flow channel plate 153.

[0062] In some embodiments of the present invention, when the second reversing valve 30 connects the water inlet interface 122 and the salt chamber 112, the salt chamber 112 is connected to the resin chamber 111, and the first reversing valve 20 is set to the first working mode. Specifically, when the softening capacity of the resin chamber 111 decreases, the second reversing valve 30 controls the water inlet interface 122 to communicate with the salt chamber 112, and the salt chamber 112 communicates with the resin chamber 111. The tap water source entering from the water inlet interface 122 first enters the salt chamber 112 and then enters the resin chamber 111. At this time, the resin chamber is connected to the washing chamber interface to facilitate the discharge of waste brine.

[0063] Combined with the foregoing, in the fourth working mode of the second reversing valve, that is, when resin regeneration is required, the first reversing valve is set to the first working mode. Exemplarily, the control system can control the linkage of the first reversing valve and the second reversing valve. When resin regeneration is required, the second reversing valve connects the water inlet interface and the salt chamber, and the salt chamber is communicated with the resin chamber. At the same time, the first port and the second port of the first reversing valve are controlled to be communicated to facilitate the discharge of waste brine.

[0064] Combined with Figure 7 , in some embodiments of the present invention, the housing main body 10 is further provided with a washing water inlet 123 and a washing water outlet 124, and a fifth flow channel 145 and a sixth flow channel 146 are provided in the housing main body 10. The plurality of interfaces include a third interface 133 and a fourth interface 134. The two ends of the fifth flow channel 145 are respectively communicated with the washing water inlet 123 and the third interface 133 and are used for feeding washing water into the water tank 200. The two ends of the sixth flow channel 146 are respectively connected to the fourth interface 134 and the washing water outlet 124 and are used for discharging the washing water of the water tank 200. The fifth flow channel 145 and the sixth flow channel 146 are arranged on the first flow channel plate 152. It should be noted that the washing water in the embodiments of the present invention refers to the water after the dishwasher completes the washing program.

[0065] Generally speaking, the dishwasher has multiple water inlets during washing, and some washing programs require heating the water to improve the washing effect of the dishwasher. The heated water is discharged to the sewer after washing. It can be understood that after the heated water completes washing, the water temperature is usually higher than room temperature when discharged, containing waste heat. If it is directly discharged to the sewer, it will cause waste of energy. By providing the interfaces and flow channels for washing water on the water softener 100, the washing water can be diverted to the water tank 200 through the water softener 100 and exchange heat with the water in the water tank 200, which can increase the initial temperature of the water in the water tank 200, realize the recovery and reuse of heat, and reduce the energy consumption required for subsequent water heating.

[0066] Specifically, combined with Figure 7 , the arrows show the flow direction of the washing water. The washing water inlet 123 can be connected to the washing chamber. The washing water containing waste heat enters the fifth flow channel 145 from the washing water inlet 123, enters the water tank 200 through the third interface 133, exchanges heat with the softened water in the water tank 200. After completing the heat exchange, it enters the water softener 100 from the fourth interface 134, flows through the sixth flow channel 146 and enters the washing chamber from the washing water outlet 124, and then is discharged from the washing chamber to the sewer. Exemplarily, the washing water can be driven into the water softener 100 by the dishwasher washing pump.

[0067] By providing a washing water inlet 123 and a washing water outlet 124 on the water softener 100, the water softener 100 is connected to the washing chamber. The water softener 100 is also provided with a fifth interface 135 and a sixth interface 136, which connect the water softener 100 to the water tank 200. And a flow channel for the washing water to flow in and out is provided inside the water softener 100, making the water softener 100 an auxiliary waterway component for washing water heat exchange. Without changing the existing structural layout of the dishwasher, through the structural design of the water softener 100, the energy recovery of the washing water is realized, avoiding the need to add pipelines for washing water heat exchange and the structures such as the support and fixation of the pipelines, reducing the leakage points, and improving the reliability of the dishwasher.

[0068] Among them, the fifth flow channel 145 and the sixth flow channel 146 can both be arranged on the first flow channel plate 152, which can shorten the flow path of the washing water, reduce energy loss, and improve the heat recovery efficiency.

[0069] Combined with Figure 7 and Figure 8 , in some embodiments of the present invention, the multiple interfaces include a fifth interface 135 and a sixth interface 136, the multiple flow channels include a seventh flow channel 147, the fifth interface 135 and the sixth interface 136 are connected to the seventh flow channel 147, one of the fifth interface 135 and the sixth interface 136 is an inlet, and the other is an outlet. That is to say, the fifth interface 135 can be an inlet and the sixth interface 136 can be an outlet; or, the sixth interface 136 can be an inlet and the fifth interface 135 can be an outlet. Among them, the outlet is configured to be connected to the heat exchanger 210 of the water tank 200. Specifically, a heat exchanger 210 can be provided inside the water tank 200. Combined with the foregoing, the waste heat of the washing water can be used to exchange heat with the softened water in the water tank 200 to realize the energy recovery of the washing water. By providing a seventh flow channel 147 on the water softener 100, the seventh flow channel 147 can be configured to divert the softened water in the water tank 200 to the heat exchanger 210 of the water tank 200 to facilitate the heat exchange of the softened water. At this time, the water softener 100 is equivalent to a waterway board. By integrating the flow channels on the water softener 100, the waterway of the dishwasher is optimized, facilitating the softened water in the water tank 200 to enter the heat exchanger 210 for heat exchange.

[0070] Furthermore, the fifth interface 135 is configured as an outlet, and the sixth interface 136 is configured as an inlet. That is to say, the softened water stored in the water tank 200 enters the seventh flow channel 147 from the fifth interface 135 and enters the heat exchanger 210 of the water tank 200 from the sixth interface 136. Combined with Figure 8 , the seventh flow channel 147 can include a first part 1471 and a second part 1472 connected to the first part 1471. The first part 1471 is connected to the fifth interface 135, and the second part 1472 is connected to the sixth interface 136.

[0071] Among them, the first part 1471 can be arranged on the main body part 151, and the second part 1472 can be arranged on the first flow channel plate 152, making full use of the space inside the water softener 100 and improving the space utilization rate of the water softener 100.

[0072] In some embodiments of the present utility model, the water softener 100 further includes a water pump 40. The water pump 40 is connected to the third side wall 115 of the housing main body 10 and communicates with the seventh flow channel 147. The water pump 40 can drive the water flow in the seventh flow channel 147. Specifically, the softened water enters the seventh flow channel 147 from the fifth interface 135, and the water pump 40 drives the water flow in the seventh flow channel 147 towards the sixth interface 136 and enters the heat exchanger 210 in the water tank 200. Among them, the seventh flow channel 147 can be a circulation flow channel. When the water pump 40 works, it drives the water in the water tank 200 to circulate through the seventh flow channel 147, so as to exchange heat with the washing water through the heat exchanger 210 and increase the initial temperature of the water in the water tank 200. When the water pump 40 is turned on, it drives the water flow in the seventh flow channel 147 to realize the circulation of the water in the water tank 200. At this time, the water softener 100 functions as a water channel plate. When the water pump 40 is turned off, the water flow in the seventh flow channel 147 is stationary.

[0073] Specifically, the water pump 40 can be connected to the first part 1471, and the water pump 40 is connected to the side wall of the housing main body 10, which can simplify the connection structure of the water pump 40 and make the structure of the water softener 100 compact.

[0074] Exemplarily, as shown in Figure 8 The arrow shows the flow direction of the water stored in the water tank 200 into the water softener 100. The water in the water tank 200 can enter the seventh flow channel 147 through the fifth interface 135, first enter the first part 1471, and be driven by the water pump 40 into the second part 1472, and then enter the heat exchanger 210 of the water tank 200 through the sixth interface 136 to exchange heat with the washing water. By reasonably arranging the water softener 100, the water softener 100 functions as a water channel plate, facilitating the leading of the softened water stored in the water tank 200 to the heat exchanger 210. Among them, the washing water in the washing cavity can be driven to flow by the washing pump of the dishwasher and enter the heat exchanger 210 of the water tank 200 through the fifth flow channel 145 integrated on the water softener 100. By integrating multiple flow channels on the water softener 100 and optimizing the pipeline, problems such as numerous pipeline connections, insufficient space position, and multi-waterway switching can be solved without changing the layout of the dishwasher, improving the adaptability and versatility of the water softener 100.

[0075] The dishwasher according to the embodiment of the present utility model includes: the aforementioned water softener 100, the water tank 200, and the washing cavity, and the water softener 100 is respectively connected to the washing cavity and the water tank 200.

[0076] As shown in Figure 10, wherein, a heat exchanger 210 is provided in the water tank 200. In combination with Figure 9 , in some specific embodiments of the present invention, the tap water source can enter from the water inlet interface. When the second reversing valve is opened (the second reversing valve is in the fourth working mode), the tap water source first enters the brine chamber to generate a brine solution, and then enters the resin chamber for regeneration and softening; if the second reversing valve is not opened (the second reversing valve is in the third working mode), the tap water source directly enters the resin chamber for softening, and the resin chamber is disconnected from the salt chamber. After the tap water source is softened by the resin chamber, it enters the first reversing valve. When the first reversing valve is opened (the first reversing valve is in the second working mode), the softened water can enter the water tank, and can be stored in the water tank or used for heat exchange. When the water discharge valve of the water tank is opened, the softened water can enter the washing chamber for washing; if the first reversing valve is not opened (the first reversing valve is in the first working mode), the softened water can directly enter the washing chamber for washing. The water softener is used to soften the water quality, and includes a softened resin chamber and a salt chamber required for regeneration. The second reversing valve is used to control the tap water source for softening or regeneration, and the softened water enters the washing chamber or the water tank through the selection of the first reversing valve. In addition, the water softener further includes a water pump, which is used to drive the flow of the surface water circuit inside the water softener, make full use of the space inside the water softener, and enable the water softener to also function as a water circuit board.
