Description

Technical Field

[0001] This utility model relates to the technical field of water softening devices, specifically to a dual-drive softening resin tank and a water softening device. Background Technology

[0002] Currently, most mainstream water softeners on the market use a single fiberglass resin tank. This single fiberglass resin tank has several disadvantages: First, it is too tall, making it difficult to fit the water softener in a small space; second, the resin tumbles inside the fiberglass tank, causing the bottom and top resins to shift, making the entire resin layer prone to losing its protective layer; and third, the resin softening path in a single tank is too short, resulting in a slightly worse softening effect at the same flow rate.

[0003] The content of the background section is merely the technology known to the inventor and does not necessarily represent the prior art in this field. Utility Model Content

[0004] To address at least one problem in the prior art, a first aspect of this utility model provides a dual-drive softening resin tank, comprising:

[0028] The specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and examples, so as to better understand the solution of this utility model and its advantages in various aspects. However, the specific embodiments and examples described below are for illustrative purposes only and are not intended to limit this utility model.

[0029] Figures 1 to 3 The present invention provides a dual-drive softening resin tank 100, comprising a first resin tank 110 and a second resin tank 120, according to an embodiment of the present invention.

[0030] Figure 1 In the illustrated embodiment, the first resin tank 110 includes a first receiving cavity A1 for containing a first resin, and the second resin tank 120 includes a second receiving cavity A2 for containing a second resin. The first resin tank 110 and the second resin tank 120 are connected to each other.

[0031] In this application, the height-to-diameter ratios of the first receiving cavity A1 and the second receiving cavity A2 are 1.2-2.5, respectively. Here, the height-to-diameter ratio is the ratio of the height of the first receiving cavity A1 to the diameter of the cross-section of the second receiving cavity A2. The height-to-diameter ratio can be used to represent the softening path length of the resin tank; that is, the larger the height-to-diameter ratio, the longer the softening path. For the entire dual-drive softening resin tank 100, its height-to-diameter ratio is 2.4-5. Such a long softening path greatly improves the softening performance of the resin tank. Under the same softening performance conditions, the flow rate can reach up to 1.5 m³ / h. 3 / h, significantly superior to existing technologies. Furthermore, the dual-drive softening resin tank 100 has separate front and rear resin tanks, preventing the first and second resins from mixing. This ensures the second resin is constantly renewed, effectively providing a protective layer that is less prone to breakdown.

[0032] Optionally, such as Figure 1 and Figure 2 As shown, the first resin tank 110 further includes a first water distributor 111, and the second resin tank 120 further includes a second water distributor 121. The first water distributor 111 and the second water distributor 121 each include a filter screen. The filter screen comprises at least six layers of filter cloth. The resin tank having at least six layers of filter cloth interception ensures that dirt and leaked resin are trapped inside the machine, thereby improving the quality of the softened water.

[0033] Optionally, such as Figure 1 and Figure 2As shown, the first resin tank 110 further includes a first central tube 112, and the second resin tank 120 further includes a second central tube 122. The first water distributor 111 includes a first upper water distributor 111a and a first lower water distributor 111b, and the second water distributor 121 includes a second upper water distributor 121a and a second lower water distributor 121b. The first upper water distributor 111a includes a first upper water distributor first part 111a-1 that cooperates with the first central tube 112, and a first upper water distributor second part 111a-2 that cooperates with the first receiving cavity A1. The first lower water distributor 111b includes a first lower water distributor third part 111b-1 that cooperates with the first central tube 112, and a first lower water distributor fourth part 111b-2 that cooperates with the first receiving cavity A1. The second upper water distributor 121a includes a first part 121a-1 of the second upper water distributor that mates with the second central tube 122, and a second part 121a-2 of the second upper water distributor that mates with the second receiving cavity A2. The second lower water distributor 111b includes a third part 121b-1 of the second lower water distributor that mates with the second central tube 122, and a fourth part 121b-2 of the second lower water distributor that mates with the second receiving cavity A2. The second part (i.e., the second part 111a-2 of the first upper water distributor, the second part 121a-2 of the second upper water distributor), the third part (i.e., the third part 111b-1 of the first lower water distributor, the third part 121b-1 of the second lower water distributor), and the fourth part (the fourth part 111b-2 of the first lower water distributor, the fourth part 121b-2 of the second lower water distributor) are each provided with a filter screen comprising at least six layers of filter cloth. This design improves the quality of soft water; furthermore, the two resin tanks have four water distributors, which means that the resin water distribution is more uniform and the resin utilization rate is higher.

[0034] Optionally, the water distribution areas of the first water distributor 111 and the second water distributor 121 are matched with the areas of the first receiving cavity A1 and the second receiving cavity A2, respectively, which results in a better water distribution effect.

[0035] Optionally, such as Figure 1 and Figure 2 As shown, the first resin tank 110 also includes a first water distributor 113, and the second resin tank 120 also includes a second water distributor 123. The first water distributor 113 is fitted onto the first part 111a-1 of the first upper water distributor 111a, and the second water distributor 123 is fitted onto the first part 121a-1 of the second upper water distributor 121a. The presence of the water distributors covers part of the area of ​​the water distributor near the central pipe, leaving the part far from the central pipe unused, thereby improving the filtration effect and thus improving the quality of the softened water.

[0036] like Figure 2As shown, the first resin tank 110 also includes a first tank cover 114, and the second resin tank 120 also includes a second tank cover 124. Optionally, the first tank cover 114 and the second tank cover 124 are connected by a connector 130.

[0037] Optionally, such as Figure 3 As shown, connector 130 includes a first flow channel 131, a second flow channel 132, and a third outlet 133. At this time, as... Figure 2 As shown, the first tank cover 114 includes a first water inlet 114a and a first water outlet 114b, and the second tank cover 124 includes a second water inlet 124a and a second water outlet 124b. The first water outlet 114b is connected to the second water inlet 124a via a first flow channel 131, and the second water outlet 124b is connected to the third water outlet 133 via a second flow channel 132. Figure 3 In the embodiment shown, the third outlet 133 is located in the middle of the connector 130.

[0038] Figure 3 In the embodiment shown, the connector 130 further includes a clip 134, which is used to control the opening and closing of the first flow channel 131 and the second flow channel 132. Lifting the clip 134 upward opens the flow channel, and inserting the clip downward closes the flow channel. Figure 3 In the illustrated embodiment, the card holder 134 includes three. In other embodiments of this application, the number of card holders 134 is not limited, as long as the corresponding function can be achieved.

[0039] Figure 4 A schematic diagram of the water circuit of the dual-drive softening resin tank is shown. Tap water enters the upper water distribution chamber of the first resin tank 110 (the space formed by the first upper water distributor 111a and the first tank cover 114) through the first inlet 114a, then passes through the second part 111a-2 of the first upper water distributor 111a into the first receiving chamber A1, where it comes into contact with the first resin. Then, it passes through the fourth part 111b-2 of the first lower water distributor 111b into the lower water distribution chamber formed by the first lower water distributor 111b and the bottom of the first resin tank 110. Next, it passes through the third part 111b-1 of the first lower water distributor 111b into the first central pipe 112, and then through the first part 111a-1 of the first upper water distributor 111a and the first outlet 114b into the first flow channel 131. Thus, softening is completed in the first resin tank 110, and the water then enters the second resin tank 120.

[0040] Semi-softened water enters the second inlet 124a from the first flow channel 131, then enters the upper water distribution chamber of the second resin tank 120 (the space formed by the second upper water distributor 121a and the second tank cover 124), then passes through the second part 121a-2 of the second upper water distributor 121a into the second receiving chamber A2, contacting the second resin, then passes through the fourth part 121b-2 of the second lower water distributor 121b into the lower water distribution chamber formed by the second lower water distributor 121b and the bottom of the second resin tank 120, then passes through the third part 121b-1 of the second lower water distributor 121b into the second central pipe 122, and then passes through the first part 121a-1 of the second upper water distributor 121a and the second outlet 124b into the second flow channel 132. Thus, softening is completed in the second resin tank 120, and finally, the softened water is discharged from the third outlet 133.

[0041] Figure 5 A schematic diagram of the water circuit of a dual-drive softening resin tank 200 according to another embodiment of this application is shown. The difference between the dual-drive softening resin tank 200 and the dual-drive softening resin tank 100 lies in the connector. Figure 5 As shown, the connector 230 between the first resin tank 210 and the second resin tank 220 of the dual-drive softening resin tank 200 includes only a one-way flow channel. The outlet of the first resin tank 210 and the inlet of the second resin tank 220 are connected through this flow channel. Tap water is softened in the first resin tank 210 and then flows through this flow channel into the second resin tank 220 for further softening, finally being discharged through the outlet of the second resin tank 220. The rest of the water circuit process is similar. Figure 4 I will not go into details.

[0042] This invention also provides a water softening device, including the aforementioned dual-drive softening resin tank. The water softening device provided by this invention has an excellent water softening effect.

[0043] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
