[0030] Combined with Figure 1 and Figure 2 , a water softener 100 according to an embodiment of the present utility model can be used in a washing device. The water softener 100 includes a housing main body 10, and the housing main body 10 is provided with a first interface 111, a second interface 112, a washing water inlet 121, a washing water outlet 122, a first flow channel 131, and a second flow channel 132. The first flow channel 131 connects the washing water inlet 121 and the first interface 111, and the second flow channel 132 connects the second interface 112 and the washing water outlet 122. The washing water inlet 121 is used to access the washing water with residual heat, the first interface 111 is used to input the washing water to the heat exchanger 300, the second interface 112 is used for the washing water to flow back from the heat exchanger 300, and the washing water outlet 122 is used to discharge the washing water.

[0031] It should be noted that the washing water in the embodiments of the present utility model refers to the waste water with residual heat after the washing device completes the washing program. Generally speaking, there are multiple water inlets during the washing process of the washing device, and some washing programs require heating the water to improve the washing effect of the washing device. After the washing program is completed, the washing water is directly discharged into the sewer. It can be understood that the temperature of the washing water is usually higher than room temperature when it is discharged and contains residual heat. If it is directly discharged into the sewer, it will cause waste of energy.

[0032] Specifically, the water softener 100 of the embodiment of the present utility model can be respectively connected to the inner tank of the washing device and the heat exchanger 300. Exemplarily, the first interface 111 and the second interface 112 can be connected to the heat exchanger 300, the washing water inlet 121 can be connected to the inner tank, and the water with residual heat can be guided to the heat exchanger 300 through the water softener 100.

The first heat exchange flow channel can be connected to the water in the water storage space 210 to form a loop, and the second heat exchange flow channel can be connected to the first interface 111 and the second interface 112. That is to say, the washing water containing residual heat enters the second heat exchange flow channel from the first interface 111 and exchanges heat with the water in the first heat exchange flow channel, thereby realizing the preheating of the water in the water tank 200; after the heat exchange is completed, the washing water flows back to the water softener 100 from the second interface 112, and flows through the second flow channel 132 and is discharged to the sewer from the washing water outlet 122.

Without changing the structural layout of the existing washing equipment, through the structural design of the water softener 100, the energy recovery of the washing water is realized, avoiding the need to add pipelines and structures such as the support and fixation of the pipelines for washing water heat exchange, reducing the leakage points, and improving the reliability of the washing equipment.

[0036] Among them, both the washing water inlet 121 and the washing water outlet 122 can be connected to the inner tank. Exemplarily, the washing equipment may further include a washing pump, and the washing water can be driven by the washing pump to enter the heat exchanger 300 through the water softener 100. After the heat exchange is completed, it can flow back to the inner tank through the washing water outlet 122 and be discharged to the sewer. The washing water inlet 121 and the washing water outlet 122 can be provided on the same side wall of the water softener 100, which can reduce the number of pipelines and facilitate the installation of the water softener 100.

[0037] Further, the first interface 111 and the second interface 112 can be provided on the first side wall of the housing main body 10, and the washing water inlet 121 and the washing water outlet 122 can be provided on the second side wall of the housing main body 10.

[0042] Combined Figure 3, in some embodiments of the present utility model, the washing water inlet 121 and the washing water outlet 122 are arranged on the main body portion 141 to facilitate the access and discharge of washing water for the water softener 100. Exemplarily, the washing water inlet 121 and the washing water outlet 122 can be connected to the water cup of the inner tank. By arranging the washing water inlet 121 and the washing water outlet 122 on the main body portion 141, it is convenient for the water softener 100 to connect to the water cup, optimizing the flow path of the washing device and making the structure of the washing device compact.

Among them, the first interface 111 and the second interface 112 are integrated on the flow channel plate 142, facilitating the connection between the water softener 100 and the heat exchanger 300. The washing water inlet 121 and the washing water outlet 122 are arranged on the main body portion 141, facilitating the connection between the water softener 100 and the inner tank. The water softener 100 integrates the flow channels for inputting washing water to the heat exchanger 300 and the flow channels for discharging washing water, avoiding the need to increase pipelines for washing water heat exchange, and optimizing the interfaces of the pipelines of the water softener 100, facilitating the docking of the heat exchanger 300, the inner tank and the water softener 100, and making the structure of the washing device compact.

[0044] Combined with Figures 2 to 4 , in some embodiments of the present utility model, the water softener 100 may further be provided with a resin cavity 150 and a water outlet interface 123 for supplying water to the inner tank. The resin cavity 150 can soften the water quality, and the water outlet interface 123 can be connected to the inner tank. The water softened by the resin cavity 150 is introduced into the inner tank through the water outlet interface 123 to reduce the deposition of calcium and magnesium ions in the water on the tableware and inside the washing device, and protect the water pipes and spraying systems of the washing device.

[0046] Combined with Figure 2, in some embodiments of the present utility model, the flow channel plate 142 has a first through hole 1421 which penetrates the flow channel plate 142 in the thickness direction, and the first through hole 1421 communicates with the first flow channel 131 and the washing water inlet 121. Combining the foregoing, the first flow channel 131 can be provided on the flow channel plate 142 to shorten the flow path of the washing water and reduce the heat loss of the washing water during the flow. The washing water inlet 121 can be provided on the main body portion 141 to facilitate the connection between the water softener 100 and the inner tank. The first through hole 1421 can connect the first flow channel 131 and the washing water inlet 121, optimize the flow path in the water softener 100, and improve the space utilization rate of the water softener 100.

[0047] Combining Figure 2 , in some embodiments of the present utility model, the flow channel plate 142 has a second through hole 1422 which penetrates the flow channel plate 142 in the thickness direction, and the second through hole 1422 communicates with the second flow channel 132 and the washing water outlet 122.

[0048] Specifically, the washing water with waste heat first enters the main body portion 141 from the washing water inlet 121, then enters the first flow channel 131 on the flow channel plate 142 through the first through hole 1421, and then enters the heat exchanger 300 from the first interface 111; after heat exchange, the washing water flows back to the second flow channel 132 on the flow channel plate 142 from the second interface 112, then enters the main body portion 141 through the second through hole 1422, and is discharged through the washing water outlet 122 of the main body portion 141.

[0049] Combining Figure 4 , in some embodiments of the present utility model, the housing main body 10 is provided with a third interface 113, a fourth interface 114, a third flow channel 133 and a fourth flow channel 134. The water softener 100 further includes a water pump 20 which is provided in the housing main body 10. The third flow channel 133 communicates with the third interface 113 and the water pump 20, and the fourth flow channel 134 communicates with the fourth interface 114 and the water pump 20.

[0050] Exemplarily, the housing main body 10 can be provided with a mounting seat for mounting the water pump 20, and the water pump 20 can be positioned on the mounting seat.

[0051] Specifically, one of the third interface 113 and the fourth interface 114 can be a water inlet, and the other is a water outlet; one of the third flow channel 133 and the fourth flow channel 134 can be an inlet water flow channel, and the other is an outlet water flow channel. Combining the foregoing, the waste heat of the washing water can be used to exchange heat with the water in the water tank 200 to achieve energy recovery of the washing water. The third flow channel 133 and the fourth flow channel 134 can cooperate to divert the water in the water tank 200 to the heat exchanger 300 and exchange heat with the washing water. At this time, the water softener 100 functions as a water circuit board. By integrating the third flow channel 133 and the fourth flow channel 134 on the water softener 100, the water circuit of the washing equipment is optimized, facilitating the water in the water tank 200 to enter the heat exchanger 300 for heat exchange, avoiding the need to add pipelines, as well as structures such as pipeline support and fixation for washing water heat exchange, reducing the water leakage points, and improving the reliability of the washing equipment.

[0052] Wherein, a water storage space 210 can be provided in the water tank 200, and the heat exchanger 300 can be provided with a first heat exchange flow channel and a second heat exchange flow channel for heat exchange cooperation. The water pump 20 can be used to connect the water storage space 210, the third flow channel 133, the fourth flow channel 134, and the first heat exchange flow channel into a loop. The second heat exchange flow channel is connected to the first interface 111 and the second interface 112. The washing water containing waste heat enters the second heat exchange flow channel from the first interface and leaves the second heat exchange flow channel from the second interface. That is to say, the first heat exchange flow channel is a cold water flow channel, and the second heat exchange flow channel is a hot water flow channel. During the heat exchange process, the water in the first heat exchange flow channel can absorb the heat of the water in the second heat exchange flow channel, realizing the recovery and reuse of the heat of the washing wastewater and reducing the energy consumption required for subsequent water heating.

[0053] Taking the third interface 113 as the water inlet and the fourth interface 114 as the water outlet as an example for illustration, the water pump 20 can drive the water flow in the third flow channel 133 and the fourth flow channel 134. Specifically, the water pump 20 can have an inlet and an outlet. The third flow channel 133 can be connected to the inlet of the water pump 20, and the fourth flow channel 134 can be connected to the outlet of the water pump 20. When the water pump 20 is working, the water in the water storage space 210 enters the third flow channel 133 from the third interface 113, enters the inlet of the water pump 20, and leaves the water pump 20 from the outlet of the water pump 20 and enters the fourth flow channel 134, and then enters the first heat exchange flow channel through the fourth interface 114 to exchange heat with the water in the second heat exchange flow channel, realizing preheating of the water in the water tank 200.

[0054] In addition, the outlet of the first heat exchange flow channel can be connected to the water storage space 210 of the water tank 200. That is to say, the third flow channel 133 and the fourth flow channel 134 can cooperate to form a part of the cold water circulation flow channel. When the water pump 20 works, it drives the water to circulate, so that the cold water exchanges heat with the washing water with waste heat through the heat exchanger 300, improving the initial temperature of the water in the water tank 200. When the water pump 20 is turned on, it drives the water in the third flow channel 133 and the fourth flow channel 134 to flow, so as to realize the circulation of the cold water in the water tank 200. At this time, the water softener 100 acts as a water circuit board. When the water pump 20 is turned off, the water flow in the third flow channel 133 and the fourth flow channel 134 is static.

[0055] By integrating the third flow channel 133 and the fourth flow channel 134 on the water softener 100, and the water pump 20 is connected to the third flow channel 133 and the fourth flow channel 134, it is convenient to realize the circulation of the water in the water tank 200 through the water softener 100. The water softener 100 acts as a water circuit board, optimizing the pipeline connection structure and facilitating the compact design of the washing equipment.

The main body part 141 is provided with a second channel 1412, and the second channel 1412 extends in the up and down direction and is opposite and communicated with the third through hole 1423 in the up and down direction. The second channel 1412 can communicate with the outlet of the water pump 20, making full use of the space inside the water softener 100 and improving the space utilization rate of the washing equipment.

[0058] In addition, the water pump 20 can be connected to the side wall of the main body part 141, which can simplify the connection structure of the water pump 20 and make the structure of the water softener 100 compact.

[0059] In some embodiments of the present utility model, the first interface 111, the second interface 112, the third interface 113 and the fourth interface 114 are arranged side by side on the same side of the housing main body 10, optimizing the heat exchange flow path and facilitating the connection of the water softener 100 with the water tank 200 and the heat exchanger 300.

At the same time, disposing the heat exchanger 300 in the water tank 200 can not change the bottom structure layout of the washing device. By setting the aforementioned water softener 100, the recovery of the waste heat of the washing water is realized, saving the installation space.

[0065] Combined with Figure 5 and Figure 6 , further, a first opening 231 and a second opening 232 are provided at the lower end of the water tank 200.

[0066] In some embodiments of the present utility model, a third opening 233 and a fourth opening 234 may also be provided at the lower end of the water tank 200. The third opening 233 may be connected to the third flow channel 133, the fourth opening 234 is connected to the fourth flow channel 134, and the third opening 233 and the third interface 113 are docked up and down, and the fourth opening 234 and the fourth interface 114 are docked in the up and down direction.

[0067] Combined with the foregoing, on the one hand, the water softener 100 can soften the water quality, and on the other hand, by setting a plurality of interfaces to be docked with the water tank 200, the recovery of the waste heat of the washing water can be realized without changing the layout of the washing device. Moreover, a plurality of flow channels are integrated in the water softener, which can reduce the structures such as the pipelines to be added for the heat exchange of the washing water, as well as the support and fixation of the pipelines, reduce the water leakage points, and improve the reliability of the washing device.
