Detailed implementation manners

[0037] In the related art, the influent flow channel is usually integrated into the breather, and the breather is connected to the water softener. Specifically, in the related art, the water from the water source is introduced into the water inlet channel in the breather, and then introduced into the water softener through the interface between the breather and the water softener. Among them, during the water inlet process, it is necessary to introduce water from the breather into the water softener, resulting in a relatively complex water path; an interface needs to be provided between the breather and the water softener, and a water leakage point is easily formed at this interface. Therefore, the present utility model provides a water softener, which integrates the influent flow channel into the water softener, and can simplify the water path.

[0038] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0039] As Figures 1 to 14, the utility model provides a water softener 100 of some embodiments, which can be used in a dishwasher. The water softener 100 includes a housing main body 10, and the housing main body 10 is provided with a water inlet 122, a water softening chamber 111 and a water outlet 121. In addition, the housing main body 10 is further provided with a water inlet structure, and the water inlet structure is connected between the water inlet 122 and the water softening chamber 111. The water inlet 122 communicates with the water softening chamber 111 through the water inlet structure. The water inlet structure is arranged in the housing main body 10, and the water outlet 121 communicates with the water softening chamber 111. The water outlet 121 can be set to supply water to the washing chamber of the dishwasher. During the water inlet process, water from a water source (such as tap water) can enter the housing main body 10 through the water inlet 122 and flow to the water softening chamber 111 through the water inlet structure. The water softening chamber 111 can be provided with a water softening medium (such as resin, etc.), which can soften the water flowing into it. The softened water can be sent to the washing chamber of the dishwasher through the water outlet 121 for cleaning tableware and the like. The water softening chamber 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, and protect the water pipes and spray systems of the dishwasher.

[0040] The water inlet structure can be set to monitor the water inlet flow rate and / or control the water inlet flow direction. Specifically, the water inlet structure can be set to detect the water inlet flow rate from the water inlet 122 to the water softening chamber 111; and / or, the water inlet structure can be set to control the water inlet flow direction from the water inlet 122 to the water softening chamber 111.

[0041] According to the water softener 100 of the embodiments of the present utility model, the water inlet structure is integrated into the water softener 100. During the water inlet process, the water from the water source can flow into the water softening chamber 111 through the water inlet structure, shortening the flow path length between the water source and the water softening chamber 111, and improving the water inlet efficiency of the dishwasher. Setting the water inlet structure originally integrated in the breather on the water softener 100 can reduce the interfaces between the water softener 100 and structures such as the breather, reduce the possible water leakage points in the water circuit system, simplify the structure of the water circuit system with the water softener 100, and optimize the structure of the water circuit system.

[0042] In addition, in some embodiments, the water outlet 121 can also be set to supply water to a water tank. Of course, the present utility model mainly takes the water outlet 121 supplying water to the washing chamber as an example for illustration, which is not a limitation on the protection scope of the present utility model.

[0043] The water softener 100 of the present utility model may include functional components. The functional components may be directly or indirectly connected to the water inlet 122 and the water softening chamber 111. To facilitate the understanding and control of the water inlet of the dishwasher, the water softener 100 of the present utility model includes a water inlet flow channel 149 and functional components. The water inlet flow channel 149 is provided in the housing main body 10, and the functional components are installed in the housing main body 10. The functional components are connected in series with the water inlet flow channel 149. The functional components are configured to monitor the flow rate of the water inlet flow channel 149 so as to understand the water inlet flow rate of the dishwasher, thereby facilitating the control of the water inlet volume. In addition, the functional components may be configured to control the flow direction of the water inlet flow channel 149.

[0044] The functional components of the present utility model may include, but are not limited to, the following embodiments and their combinations.

[0045] Embodiment 1

[0046] As Figure 2 , the functional components include a first flow rate monitoring unit 51. The first flow rate monitoring unit 51 is provided in the housing main body 10 and is connected in series with the water inlet flow channel 149. The first flow rate monitoring unit 51 is used to monitor the water flow rate of the water inlet flow channel 149. The water flow rate of the water inlet flow channel 149 can be detected by the first flow rate monitoring unit 51 so as to timely understand the water inlet situation. Specifically, the water inlet 122 may be connected in series with a water inlet valve, and the quantitative water inlet of the dishwasher can be realized through the cooperation of the water inlet valve and the first flow rate monitoring unit 51, avoiding too much or insufficient water volume introduced into the dishwasher, thereby improving the washing efficiency and effect of the dishwasher. In addition, the water inlet volume can also be adjusted according to different washing modes, different numbers of tableware, or different types of tableware, etc. Among them, setting the first flow rate monitoring unit 51 in the housing main body 10 can improve the integration degree of the water softener 100, and integrating the flow meter provided in the breather in the related art onto the water softener 100 can simplify the structure of the breather.

[0048] As Figure 3 , the functional components include a first one-way control unit 54. The first one-way control unit 54 is provided in the housing main body 10 and is connected in series with the water inlet flow channel 149. The first one-way control unit 54 controls the water flow to flow unidirectionally along the direction from the water inlet 122 to the water softening chamber 111. The flow direction of the water inlet can be controlled by the first one-way control unit 54, avoiding the problem of water backflow caused by unbalanced air pressure during the water inlet process, and realizing the function of preventing siphonage of the water inlet.

[0049] Embodiment 3

[0050] As Figure 4, the functional components include a second flow monitoring unit 52 and a second one-way control unit 55 connected in series. The second flow monitoring unit 52 is used to monitor the water flow rate in the water inlet channel 149, and the second one-way control unit 55 controls the water flow to circulate unidirectionally along the direction from the water inlet 122 to the soft water chamber 111. The water flow rate in the water inlet channel 149 can be detected by the second flow monitoring unit 52 to facilitate timely understanding of the water inlet situation. The flow direction of the inlet water can be controlled by the second one-way control unit 55 to avoid the problem of water backflow caused by unbalanced air pressure during the water inlet process, achieving the function of preventing siphonage during water inlet.

[0051] Embodiment 4

[0052] As Figure 5 , the functional components include a third flow monitoring unit 53, and the third flow monitoring unit 53 is integrated with a third one-way control unit 56. The third flow monitoring unit 53 is used to monitor the water flow rate in the water inlet channel 149, and the third one-way control unit 56 controls the water flow to circulate unidirectionally along the direction from the water inlet 122 to the soft water chamber 111. The flow direction of the inlet water can be controlled by the third one-way control unit 56 to avoid the problem of water backflow caused by unbalanced air pressure during the water inlet process, achieving the function of preventing siphonage during water inlet. In addition, integrating the third one-way control unit 56 with the third flow monitoring unit 53 can simplify the structure of the water softener 100, improve the assembly and maintenance efficiency of the water softener 100, and increase the integration degree of the water softener 100.

[0053] As Figure 6 and Figure 7 , in some embodiments, the functional components are arranged on the side wall of the housing main body 10. The housing main body 10 is provided with a first opening 1497 and a second opening 1498. The functional components communicate with the first opening 1497 and the second opening 1498. The first opening 1497 communicates with the water inlet 122, and the second opening 1498 communicates with the soft water chamber 111. The installation of the functional components can be facilitated, and the functional components can include the functional components shown in the foregoing embodiments to meet the requirements of preventing siphonage and flow monitoring of the water inlet channel 149. In addition, the water inlet 122 and the functional components in the present utility model can be arranged on the same side wall of the housing main body 10 or on different side walls of the housing main body 10.

[0054] Furthermore, the housing main body 10 is further provided with a salt chamber 112. The soft water chamber 111 communicates with the salt chamber 112. The water softener 100 further includes: a regeneration valve 30. The regeneration valve 30 communicates with the second opening 1498, the soft water chamber 111 and the salt chamber 112. The regeneration valve 30 is used to control the water flow to flow through the water inlet channel 149 to the soft water chamber 111 or the salt chamber 112.

[0055] Exemplarily, the regeneration valve 30 has a third operating mode and a fourth operating mode. In the third operating mode, the water inlet channel 149 is connected to the soft water chamber 111, and preferably the salt chamber 112 is disconnected from the soft water chamber 111. In the fourth operating mode, the water inlet channel 149 is connected to the salt chamber 112, and the salt chamber 112 is connected to the soft water chamber 111. Combining the foregoing, when the regeneration valve 30 is in the fourth operating mode, that is, when resin regeneration is required, the reversing valve 20 is set to the first operating mode.

[0056] Specifically, the water inlet channel 149 can be connected to a tap water source. Resin can be provided in the soft water chamber 111, and regeneration salt can be added to the salt chamber 112. When the calcium, magnesium and other ions adsorbed by the resin in the soft water chamber 111 are saturated, the softening capacity of the soft water chamber 111 decreases, and the salt in the salt chamber 112 is required to regenerate the resin. The regeneration valve 30 can control the tap water entering through the water inlet channel 149 to enter the soft water chamber 111 for softening, or first enter the salt chamber 112 to form a brine solution and then enter the soft water 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, protecting the dishwasher and tableware, and at the same time extending the service life of the dishwasher.

[0057] Among them, the regeneration valve 30 can control the water inlet channel 149 to communicate with the soft water chamber 111, and the soft water chamber 111 is disconnected from the salt chamber 112. The tap water source entering through the water inlet channel 149 is softened by the soft water chamber 111 and then controlled by the reversing valve 20 to enter the water tank or the washing chamber. When the softening capacity of the soft water chamber 111 decreases, the regeneration valve 30 can control the water inlet channel 149 to communicate with the salt chamber 112, and the salt chamber 112 is connected to the soft water chamber 111. The tap water source entering through the water inlet channel 149 first enters the salt chamber 112 and then enters the soft water chamber 111. The softened water is controlled by the reversing valve 20 to enter the water tank or the washing chamber. By setting the cooperation of the reversing valve 20 and the regeneration valve 30, the switching of the water path is realized, and both the reversing valve 20 and the regeneration valve 30 are integrated in the water softener 100, so as to facilitate the switching of the water path within the water softener 100, simplify the pipeline connection of the dishwasher, and improve the space utilization rate of the dishwasher.

[0058] Combined with Figure 9 and Figure 14, the housing main body 10 includes a main body portion 151 and a second flow channel plate 142. The second flow channel plate 142 is connected to the lower end portion of the main body portion 151. A regeneration valve 30 and functional components are provided in the main body portion 151. A ninth flow channel 1491 and a tenth flow channel 1492 are provided between the main body portion 151 and the second flow channel plate 142. The main body portion 151 is provided with a first channel 1493, a second channel 1494, a third channel 1495, and a fourth channel 1496 extending in the up and down direction. The first channel 1493 communicates with a first opening 1497 and the ninth flow channel 1491. The second channel 1494 communicates with a water inlet 122 and the ninth flow channel 1491. The third channel 1495 communicates with a second opening 1498 and the tenth flow channel 1492. The fourth channel 1496 communicates with the regeneration valve 30 and the tenth flow channel 1492. The structure of the housing main body 10 can be simplified, facilitating the construction of the flow channels.

[0059] Combined Figures 6 to 14 , in some embodiments of the present utility model, the dishwasher may further include a water tank, and the water softener 100 can be used to supply water to the water tank. Optionally, as Figure 6 and Figure 8 , the housing main body 10 is further provided with a first interface 131 for supplying water to the water tank. The water softener 100 further includes: a reversing valve 20 provided in the housing main body 10. The reversing valve 20 communicates with a soft water chamber 111, a water outlet 121, and the first interface 131 respectively. The reversing valve 20 has a first working mode and a second working mode. In the first working mode, the soft water chamber 111 is connected to the water outlet 121. In the second working mode, the soft water chamber 111 communicates with the first interface 131.

[0060] Exemplarily, the dishwasher can be set with multiple washing programs. In washing programs such as pre-rinsing and quick washing, the water softened in the soft water chamber 111 can be directly introduced into the washing chamber to reduce the deposition of calcium and magnesium ions in the water on the tableware and inside the dishwasher, protect the water pipes and spray systems of the dishwasher, and improve the water usage efficiency. In some washing programs, the water softened in the soft water chamber 111 can be first introduced into the water tank, and the water tank can store the softened water to facilitate providing a stable water flow for the washing chamber. In some washing programs, hot water is required for cleaning. The water softened in the soft water chamber 111 can be first introduced into the water tank, and a heat exchanger can be provided in the water tank to preheat the softened water to increase the initial temperature of the softened water. Therefore, in different washing programs, the flow direction of the softened water is different. By integrating the reversing valve 20 on the water softener 100, the water path switching can be completed in the water softener 100 to meet the requirements of diverse washing programs. In addition, integrating the reversing valve 20 into the water softener 100 facilitates the water path switching of the water flow in the water softener 100 and simplifies the water path design of the dishwasher.

[0061] Among them, the reversing valve 20 can switch the flow direction of water. Exemplarily, the reversing valve 20 can be a two-position three-way valve, and the water softened by the soft water chamber 111 can be selectively controlled to flow to the water outlet 121 or the first interface 131 through the two-position three-way valve; alternatively, the reversing valve 20 can be a solenoid valve, and the opening or closing of the channel between the soft water chamber 111 and the water outlet 121, and the opening or closing of the channel between the soft water chamber 111 and the first interface 131 can be controlled by energizing or de-energizing. Of course, the reversing valve 20 can also be set to other types of valves, and the type of the reversing valve 20 is not limited in this application.

[0062] In addition, the reversing valve 20 can be directly connected to the soft water chamber 111, the water outlet 121, and the first interface 131, or can be connected and communicated through a flow channel. Exemplarily, a plurality of flow channels can be provided in the housing main body 10, and the plurality of flow channels can be distributed at different positions of the housing main body 10. For example, they can be at the upper end, the lower end, or the middle part of the housing main body 10, etc., so as to facilitate the switching of the water path in the water softener 100 and improve the space utilization rate in the water softener 100.

[0065] Combined Figure 9 and Figure 10, Further, the reversing valve 20 has a first port 21, a second port 22, and a third port 23. The first port 21 communicates with the first flow channel 141, the second port 22 communicates with the second flow channel 142, and the third port 23 communicates with the third flow channel 143.

By providing the first branch 1431 and the second branch 1432, the structure of the flow channel is optimized, and the space inside the water softener 100 is fully utilized.

[0069] Combined with the foregoing, the shell body 10 may further include a second flow channel plate 153, which is provided at the lower end of the shell body 10. The first flow channel plate 152, the main body part 151, and the second flow channel plate 153 may be arranged in sequence in the up-down direction. A plurality of interfaces are provided on the first flow channel plate 152. The shell body 10 is further provided with a plurality of flow channels, and the plurality of flow channels are provided in the main body part 151, the first flow channel plate 152, and the second flow channel plate 152.

[0070] Optionally, combined with Figures 9 to 14 , the incoming water flow channel 149 may be provided in the second flow channel plate 153.

[0071] Among them, the water outlet 121 and the first interface 131 may be located on opposite sides of the water softener 100 respectively. The water softener 100 is used as an intermediate component between the washing chamber and the water tank, which is convenient for pipeline connection and makes the structure of the dishwasher compact. Of course, the water outlet 121 and the first interface 131 may also be provided on the same side or adjacent sides of the water softener 100, etc., and can be specifically adjusted according to the structure of the dishwasher.

[0072] Combined with Figure 8 and Figure 12 , in some embodiments of the present invention, the shell body 10 is further provided with a second interface 132 and a fourth flow channel 144. One end of the fourth flow channel 144 communicates with the second interface 132, and the other end of the fourth flow channel 144 communicates with the water outlet 121 or the soft water chamber 111. In addition, the water tank may be provided with a water discharge port and a water discharge valve for opening and closing the water discharge port. The water discharge port is connected to the second interface 132. That is to say, the channel between the water discharge port and the second interface 132 can be opened and closed through the water discharge valve. When the water discharge valve is opened, water can be passed into the water softener 100 through the water discharge port, and the water can be guided to the washing chamber through the water softener 100. Among them, when the water discharge valve is opened, the reversing valve 20 is in the first working mode.

[0073] Specifically, the second interface 132 can be connected to a water tank, and the softened water stored in the water tank can be diverted to the washing chamber through the second interface 132. When it is necessary to use the softened water in the water tank, the water discharge valve is opened, and the softened water enters the fourth flow channel 144 from the second interface 132. Subsequently, the water in the fourth flow channel 144 can flow into the first port 21 or the second port 22 of the reversing valve 20. Among them, after the water in the fourth flow channel 144 flows through the first port 21, the reversing valve 20 can be in the first working mode, the second port 22 is communicated with the first port 21, and the softened water entering the first flow channel 141 enters the washing chamber from the water outlet 121; alternatively, after the water in the fourth flow channel 144 flows through the second port 22, it enters the washing chamber from the water outlet 121.

[0074] In some embodiments of the present invention, the water outlet 121 can be configured to be connected to a 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 water softening chamber 111 can be directly connected to the water cup through the water outlet 121, or first enter the water tank 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, reducing the water leakage points, and saving the installation space of the dishwasher. Exemplarily, the water outlet 121 and the water cup can be connected by a pipeline. Combining Figure 11 and Figure 12 , in some embodiments of the present invention, a water softening chamber inlet 1111 is provided at the lower end of the water softening chamber 111 and a water softening chamber outlet 1112 is provided at the upper end in the up and down direction, and the water softening chamber outlet 1112 is communicated with the reversing valve 20 through the first flow channel 141.

[0075] Specifically, the tap water source can enter the water softening chamber 111 from below the water softening chamber 111. After being softened by the resin, it can enter the reversing valve 20 from above the water softening chamber 111 through the first flow channel 141, and the water path is switched by the reversing valve 20, and it can selectively enter the washing chamber or enter the water tank. Among them, the water softening chamber outlet 1112 is provided above the water softening chamber 111, which is convenient for the tap water to fully contact the resin, improving the water softening efficiency and effect.

[0076] Furthermore, the 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 reversing valve 20 and the housing main body 10, and is also convenient for switching the water path of the softened water through the reversing valve 20. The water outlet 121 is connected to the second side wall 114 of the housing main body 10, and the first side wall 113 and the second side wall 114 are adjacent. Specifically, the water outlet 121 can be used to connect to the washing chamber. When the reversing valve 20 connects the second flow channel 142 and the first flow channel 141, the water softened by the water softening 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.

[0077] Optionally, the second interface 132 and the first interface 131 are arranged side by side on the housing body 10. Thus, it is convenient for the water softener 100 to be connected to the water tank. The first interface 131 is used to supply water to the water tank, and the second interface 132 is used to drain the water in the water tank.

[0078] In some embodiments, the housing body 10 may further be provided with a washing water inlet and a third interface. A fifth flow channel is provided in the housing body 10. The two ends of the fifth flow channel are respectively communicated with the washing water inlet and the third interface, and are used to supply washing water to the water tank. Optionally, the fifth flow channel is arranged on the first flow channel plate 15.

[0079] In other embodiments, the housing body 10 may further be provided with a washing water inlet, a washing water outlet, a fifth flow channel, a sixth flow channel, a third interface and a fourth interface. The two ends of the fifth flow channel are respectively communicated with the washing water inlet and the third interface, and are used to supply washing water to the water tank. The two ends of the sixth flow channel are respectively connected to the fourth interface and the washing water outlet, and are used to drain the washing water in the water tank. The fifth flow channel and the sixth flow channel are arranged on the first flow channel plate 152. It should be noted that the washing water in the embodiments of the present utility model refers to the water after the dishwasher completes the washing program.

[0080] In some embodiments of the present utility model, the housing body 10 further includes a fifth interface and a sixth interface. The plurality of flow channels include a seventh flow channel and an eighth flow channel. The fifth interface is connected to the seventh flow channel, and the sixth interface is connected to the eighth flow channel. A water pump 40 is connected between the seventh flow channel and the eighth flow channel.

[0081] Specifically, a heat exchanger may be provided in the water tank. Optionally, the softened water stored in the water tank enters the seventh flow channel from the fifth interface, flows through the water pump 40 and then flows to the eighth flow channel, and then enters the first heat exchange channel of the heat exchanger from the sixth interface; the washing water containing waste heat enters the fifth flow channel from the washing water inlet, exchanges heat through the second heat exchange channel of the heat exchanger via the third interface, and the first heat exchange channel and the second heat exchange channel cooperate in heat exchange. After the heat exchange is completed, the washing water can enter the water softener 100 from the fourth interface, flow through the sixth flow channel, enter the washing cavity from the washing water outlet, and then be discharged to the sewer from the washing cavity. Exemplarily, the washing water can be driven into the water softener 100 by the dishwasher washing pump.

[0082] Generally speaking, a dishwasher has multiple water intakes during washing, and some washing programs require heating the water to improve the washing effect of the dishwasher. The heated water is discharged into the sewer after the washing is completed. It can be understood that after the washing is completed, the water temperature of the discharged heated water is usually higher than the room temperature and contains residual heat. If it is directly discharged into the sewer, it will cause waste of energy. By providing an interface and a flow channel for the washing water on the water softener 100, the washing water can be diverted through the water softener 100 into the water tank and exchange heat with the water in the water tank, which can increase the initial temperature of the water in the water tank, realize the recovery and reuse of heat, and reduce the energy consumption required for subsequent water heating.

[0083] In some embodiments of the present invention, 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 body 10 and communicates with the seventh flow channel and the eighth flow channel. The water pump 40 can drive the water flow in the seventh flow channel and the eighth flow channel. Specifically, the softened water enters the seventh flow channel from the fifth interface, and the water pump 40 drives the water flow in the eighth flow channel to flow towards the sixth interface and enter the heat exchanger in the water tank.

[0084] The dishwasher according to an embodiment of the present invention includes: the aforementioned water softener 100 and a water cup, and the water cup communicates with the water outlet 121.

[0085] Optionally, the dishwasher may further include: a water tank and a washing cavity, and the water softener 100 is respectively connected to the washing cavity and the water tank.

[0086] Optionally, a heat exchanger is provided in the water tank. In combination with Figures 1 to 14, in some specific embodiments of the present utility model, the tap water source can enter from the water inlet flow channel 149. When the regeneration valve 30 is opened (the regeneration valve 30 is in the fourth working mode), the tap water source first enters the salt chamber 112 to generate a brine solution, and then enters the soft water chamber 111 for regeneration and softening; if the regeneration valve 30 is not opened (the regeneration valve 30 is in the third working mode), the tap water source directly enters the soft water chamber 111 for softening, and the soft water chamber 111 is disconnected from the salt chamber 112. After the tap water source is softened by the soft water chamber 111, it enters the reversing valve 20. When the reversing valve 20 is opened (the reversing valve 20 is in the second working mode), the softened water can enter the water tank, where it 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 reversing valve 20 is not opened (the reversing valve 20 is in the first working mode), the softened water can directly enter the washing chamber for washing. The water softener 100 is used to soften the water quality, including the softened water chamber 111 and the salt chamber 112 required for regeneration. The regeneration valve 30 is used to control the tap water source for softening or regeneration, and the softened water is selected to enter the washing chamber or the water tank through the reversing valve 20. In addition, the water softener 100 further includes a water pump 40, which is used to drive the flow of the water path on the inner surface of the water softener 100, make full use of the space inside the water softener 100, and enable the water softener 100 to also function as a water path board.
