Description

TECHNICAL FIELD

[0001] The present application relates to the field of water treatment, in particular to a salt tank with double regeneration tanks, and a water softener with the double regeneration tank salt tank. BACKGROUND

[0002] The water softener mainly uses ion exchange resin for ion exchange, and the calcium and magnesium ions in the water are adsorbed by the resin, thereby reducing the hardness of the water. When the ion exchange resin reaches adsorption saturation, the resin needs to be regenerated to restore its softening capacity. A certain concentration of sodium chloride solution is generally used to achieve the effect of resin regeneration. Currently, small water softeners mostly adopt a single regeneration tank structure.

[0003] For households with a large amount of daily water consumption or areas with hard water, especially small water softeners with a low height (installed under the kitchen), the water softener will undergo multiple regeneration processes in a day. When the resin in the single regeneration tank structure is being regenerated, it will not soften the water. At this time, the water softener cannot provide 24-hour continuous and uninterrupted soft water supply, and cannot provide high-flow soft water. The existing technology usually adopts a solution to replace large water softeners to meet the water demand. However, large water softeners are usually installed in equipment rooms or equipment balconies (with a large installation space), which can meet the demand for high-hardness water quality and high-flow soft water. However, due to the large size of the equipment, it is difficult to meet the use requirements of places with limited installation space.

[0004] Chinese patent CN202210158144.4 discloses a multi-way valve, a water softener, and a control method of the water softener. The multi-way valve is provided with a main valve and a secondary valve. When the main valve and the secondary valve are in the bypass valve position, the water inlet channel, the first main valve channel, the first secondary valve channel, the second secondary valve channel, the second main valve channel, and the water outlet channel of the multi-way valve are sequentially connected to form a bypass flow path in the valve, thereby realizing the bypass function without the need for an external bypass valve installed on the user's water supply pipeline, and avoiding the risk of water leakage caused by the external bypass valve. In addition, the use of valve position switching to realize bypass and other functions facilitates automatic control, improves adaptability to some extent, and better adapts to the application of double regeneration tank continuous water supply water softeners. The water softener can realize double regeneration tank continuous water supply, automatic bypass in the valve, water mixing, water leakage detection shutdown, and regeneration salt detection alarm functions, meeting the user's use requirements and ensuring water safety. Although this scheme provides a double regeneration tank water softener solution, the inlet and outlet water directions of this scheme are towards the rear side, and the depth dimension is relatively large. The depth space is insufficient, and the double regeneration tank occupies a large amount of depth space, resulting in a small salt addition port. The inlet and outlet connectors cannot be installed on the rear side of the kitchen, and must be installed first and then placed in, and the pipeline also needs to be reserved longer. SUMMARY

[0005] The summary of this invention introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This summary is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] The technical problem to be solved by the present invention is to provide a dual-regeneration tank salt tank with a small footprint, convenient salt addition operation, and the ability to avoid large-area salt agglomeration and salt bridge formation. Also, a water softener having the aforementioned dual-regeneration tank salt tank is provided.

[0007] To solve the above-mentioned technical problems, the present invention provides a dual regeneration tank salt tank, comprising:

[0008] Salt tank 1, which is used to house the dual regeneration tank assembly and the salt valve salt well 14;

[0009] An isolation assembly, arranged inside the salt tank 1, divides the salt tank 1 into a first chamber and a second chamber;

[0010] A dual regeneration tank assembly, located in the first chamber, comprises two regeneration tanks forming a redundant structure;

[0011] Salt valve salt well 14, which is fixed in the first chamber;

[0012] Salt inlet 30, which is formed at the top of the second chamber;

[0013] The salt tank drain connector 12 is formed on the side wall of the salt tank 1 opposite to the salt inlet 30;

[0014] An overflow connector 13 is formed on the side wall of the salt tank 1 below the salt tank drain connector 12;

[0015] Alternatively, the dual regeneration tank salt container may be further improved, with the isolation assembly including:

[0016] The salt grid plate 10 is arranged vertically perpendicular to the bottom wall of the salt tank 1, and its lower half has a plurality of first water permeable holes 18; the first water permeable holes 18 are used for the up and down flow of brine and the diffusion of brine.

[0017] The bottom plate is formed on one side of the bottom of the salt grid plate 10 in the second chamber, and a plurality of second water permeable holes 20 are formed on it; the second water permeable holes 20 are used for the up and down flow of brine and the diffusion of brine, and help the brine reach saturation.

[0018] A partition 19 is formed on the side wall of the salt grid plate 10 facing the second chamber. Its horizontal direction is perpendicular to the salt grid plate 10, and its vertical direction is perpendicular to the bottom wall of the salt tank 1. The partition 19 divides the salt into two smaller areas to prevent large-area salt agglomeration and the formation of salt bridges.

[0019] Alternatively, the dual regeneration tank salt box can be further improved by dividing the lower half of the second chamber into two spaces by partition 19, and dividing the multiple first water-permeable holes 18 into the two spaces by partition 19.

[0020] The first permeable hole 18 is formed only on the salt barrier plate 10 below the maximum height of the partition plate 19.

[0021] Alternatively, the dual regeneration tank salt box can be further improved by forming the partition 19 into a fin shape, with the longer side of the partition formed on the salt grid plate 10.

[0022] Optionally, the dual regeneration tank salt box can be further improved by having multiple first water-permeable holes 18 arranged in equal rows in the vertical direction, with the number of first water-permeable holes 18 gradually decreasing from the bottom of the salt grid plate 10 to the top of the salt grid plate 10, and the rows formed by the first water-permeable holes serving as indicators of the brine height position.

[0023] Alternatively, the dual regeneration tank salt box may be further improved by including two parallel mounting slots 29 for connecting and fixing the regeneration tank base 28.

[0024] Alternatively, the dual regeneration tank salt box can be further improved, with the salt valve and salt well 14 located in the middle of the two mounting slots 29.

[0025] Optionally, the dual regeneration tank salt box can be further improved by having the salt inlet 30 be angled from the center of the salt box to the edge of the salt box.

[0026] To solve the above-mentioned technical problems, the water softener provided by the present invention, having any one of the above-mentioned dual regeneration tank brine tanks, further includes:

[0027] Salt cap 8, which is attached to the salt inlet 30;

[0028] The middle cover assembly 9 has its cover mounted on the salt tank 1;

[0029] The upper cover assembly 6 is mounted on the middle cover assembly 9, and together with the middle cover assembly 9, they form an accommodating space.

[0030] Control valve 5, which is arranged in the accommodating space, is connected to the dual regeneration tank assembly and bypass valve 4 respectively;

[0031] Bypass valve 4 is located at the opening on the side wall of the upper cover assembly 6;

[0032] The display control box 7 is formed on one side wall of the upper cover assembly 6 and is connected to the control valve 5;

[0033] The sewage pipe 11 is connected to the control valve 5 at one end and to the sewage discharge connector 12 of the salt tank at the other end.

[0034] Alternatively, the water softener can be further improved by connecting and fixing the bypass valve 4 and the control valve 5 with quick-connect clamps 27.

[0035] This invention can achieve at least the following technical effects;

[0036] 1. This invention achieves miniaturized integration of equipment with a redundant dual regeneration tank structure.

[0037] 2. The isolation component designed in this invention can prevent large-area salt agglomeration and the formation of salt bridges.

[0038] 3. This invention adopts a modular design, which occupies little space and is easy to install, repair and replace.

[0039] 4. In this invention, one end of the drain pipe is connected to the control valve with a built-in drain port. The drain pipe runs inside the brine tank, and the other end extends out of the side wall of the brine tank. The drain pipe can be pre-installed in a concealed manner, solving the technical problems of inconvenient and unsightly drain management and installation. For example, the drain connector and overflow connector are located on the rear side of the water softener, set in a recess in the side wall of the brine tank, avoiding protrusion from the water softener's outline and space occupation.

[0040] 5. The salt inlet of this invention is designed with an outward slant, which facilitates salt addition and observation, and avoids the inconvenience of adding salt in some low spaces, such as under-sink spaces, where the machine needs to be moved outside the cabinet to add salt.
