Description

Technical Field

[0001] The utility model belongs to the technical field of soft water, and in particular relates to a soft water system which does not affect water intake. Background Art

[0002] The water softener uses ion exchange technology to exchange the functional ions on the resin with the calcium and magnesium ions in the water, absorb the excess calcium and magnesium ions in the water, and reduce the hardness of the water. After a period of operation, the resin in the water softener will reach the adsorption saturation state, and the softening capacity will be reduced to the limit. Therefore, it is necessary to use special salt water to flush and regenerate to restore the softening capacity of the resin.

[0003] When the resin in the resin tank of the existing water softener is regenerating, the resin tank cannot soften the raw water, resulting in the user being unable to draw water. The user must wait for the resin to regenerate and restore the softening function before the water softener can soften the water again and the user can draw water. As a result, the water softener cannot continuously produce soft water, and there must be a period of time when the user cannot draw water, which greatly reduces the user experience.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-2The present application provides a soft water system that does not affect water intake, including at least two resin tanks 1 and a brine tank 2 connected in parallel, wherein the resin tank 1 is provided with a softening valve 11, a brine intake port 12, a wastewater port 13, a first water inlet 14 and a first soft water outlet 15, wherein the first water inlet 14 is connected to a water source, and the first soft water outlet 15 outputs soft water. The brine tank 2 is provided with a brine outlet 21, and the brine outlet 21 is connected to the brine intake port 12. In actual use, the first water inlet 14 is connected to a water source connection pipe 5, and raw water is transported from the first water inlet 14 to the resin tank 1, and soft water is obtained after the resin ions in the resin tank 1 are exchanged, and the soft water is output from the first soft water outlet 15. The softening valve 11 is used to control the resin tank 1 to produce soft water or absorb salt water for flushing and regeneration. In this embodiment, the softening valve 11 is a prior art. When the resin tank 1 produces soft water, the softening valve 11 makes the first water inlet 14 and the first soft water outlet 15 in a conducting state, that is, raw water can flow into the resin tank 1 from the first water inlet 14, and the soft water softened by the resin is output from the first soft water outlet 15 for users to use. After the resin tank 1 has worked for a period of time, the resin tank 1 needs to absorb salt water for flushing and regeneration. At this time, the softening valve 11 makes the first water inlet 14 and the first soft water outlet 15 in a closed state, and the salt water in the salt water tank 2 enters the resin tank 1 from the salt water intake port 12, and the salt water flushes and regenerates the resin, and the generated wastewater flows out from the waste water outlet 13.

[0030] In this embodiment, at least two resin tanks are connected in parallel so that each resin tank works independently. The corresponding resin tanks are controlled by softening valves to be in the soft water production or regeneration state, so that all the resin tanks can produce soft water together to meet the large water demand of users; when some of the resin tanks are in the soft water production state, the other part of the resin tanks are in the regeneration state, and the working state is alternately changed in this way, so that the entire soft water system is in a continuous soft water production state without affecting the water intake of users.

[0031] For details, please refer to Figure 1 In this embodiment, two resin tanks 2 are connected in parallel, and the raw water connecting pipe 5 is connected to the first water inlets 14 of the two resin tanks 2 through a two-way pipe, that is, the raw water can be diverted into two branches; correspondingly, the two first soft water outlets 15 are connected to the water pipe 4 at the water use end through a three-way pipe. When the water consumption is large during the day or at night, the soft water system of the present application can also produce soft water with two resin tanks 2.

[0032] In one embodiment, see Figure 2-3 The soft water system of the present application which does not affect water intake also includes an integrated waterway plate 3, through which the resin tanks 2 are connected in parallel, thereby reducing the use of connecting elbows such as tees.

[0033] In this implementation, see Figure 4-7 The integrated waterway board 3 is provided with an independently separated raw water pipe 31 and a soft water pipe 32. The raw water pipe 31 connects the water source to the first water inlet 14, that is, the raw water pipe 31 is connected with the water source connecting pipe 5, and the water source is transported to the first water inlet 14, and then flows into the resin tank 2. The soft water pipe 32 is connected with the first soft water outlet 15, and the soft water softened by the resin tank 2 is output, that is, the soft water flows out from the first soft water outlet 15, and then output to the water use end through the first soft water pipe 32. In actual installation, the first soft water pipe 32 is connected with the water pipe 4 at the water use end.

[0034] In this embodiment, the raw water pipe 31 is provided with a raw water inlet 3111 and a plurality of water outlets 3121, and the number of the water outlets 3121 is the same as the number of the resin tanks 2. In this embodiment, the resin tanks 2 are provided with two, and correspondingly, the water outlets 3121 are provided with two. The raw water inlet 3111 is connected to the water source, and the water outlet 3121 is connected to the first water inlet 14. Raw water flows into the inner cavity of the raw water pipe 31 from the raw water inlet 3111, flows out from the water outlet 3121, and flows into the resin tank 2 through the first water inlet 14. The soft water pipe 32 is provided with a second soft water outlet 321 and a plurality of soft water inlets 322, and the number of the soft water inlets 322 is the same as the number of the resin tanks 2. The first soft water outlet 15 is connected to the soft water inlet 322, and the second soft water outlet 15 is connected to the soft water inlet 322. The soft water softened by the resin tank 2 flows out from the first soft water outlet 15, flows into the soft water pipe 32 through the soft water purification port 322, and flows out from the second soft water outlet 321 to the water use end.

[0035] In order to facilitate the connection with the water end, the soft water pipe 32 is provided with a water outlet 323, which is connected to the water pipe 4 of the water end through the water outlet 323. Specifically, the water outlet 323 is installed at the second soft water outlet 321, one end of the water outlet 323 is embedded with the second soft water outlet 321, and the other end is rounded for easy connection with the water pipe.

[0036] In one embodiment, please refer to 4-5, the raw water pipeline 31 includes a main pipeline 311 and a branch pipeline 312, the main pipeline 311 is connected to the branch pipeline 312, the raw water inlet 3111 is arranged on the main pipeline 311, and the outlet 3121 is arranged on the branch pipeline 312.

[0037] In another embodiment, see Figure 6-7The raw water pipeline 31 includes a main pipeline 311 and a branch pipeline 312 . The main pipeline 311 is connected to the branch pipeline 312 . The raw water inlet 3111 is arranged on the branch pipeline 312 . The outlet 3121 is arranged on the branch pipeline 312 .

[0038] In actual use, the raw water inlet 3111 can be set on the main pipeline 311 or the branch pipeline 312 according to the location of the water source.

[0039] In one embodiment, see Figure 8 The brine tank 2 is provided with a liquid level detector 22 for detecting the height of the brine in the brine tank 2 to avoid empty pumping during the resin flushing and regeneration operation. The brine outlet 21 is provided with a solenoid valve 23, and the outflow of brine is controlled by the solenoid valve 23. In this embodiment, at least two brine outlets 21 are provided, which is the same as the number of the resin tanks 2, that is, one brine outlet 21 corresponds to one brine intake port 12.

[0040] The present application also provides a method for controlling a soft water system without affecting water intake, the system being the above-mentioned soft water system, and the control method comprising the following steps:

[0041] S1: Obtain water production instruction, open at least one resin tank to produce soft water, and the remaining resin tanks are closed to produce soft water or regenerate and flush;

[0042] S2: After working for a predetermined time, the resin tank in the soft water producing state is switched to the regeneration flushing state, and the remaining resin tanks are opened to the soft water producing state.

[0043] Specifically, different numbers of resin tanks can be turned on according to the water production instructions obtained in different time periods to meet the user's demand for soft water. For example, during the peak water use period at night, only one resin tank can be turned off to produce soft water or regenerate and flush, and the other multiple resin tanks can be in the state of producing soft water, so as to meet the user's multiple uses such as bathing and washing dishes; or, during the peak water use period, a period of time is set for all resin tanks to be in the state of producing soft water, and when the working time reaches the preset time, at least one of the resin tanks is turned off to produce soft water for regeneration and flushing. When it is in the low-peak water use period late at night and early in the morning, only one resin tank can be turned on to produce soft water, and the other resin tanks can be regenerated and flushed. After setting the preset working time, the resin tank in the state of producing soft water will be converted to regeneration and flushing, and correspondingly, the other resin tanks will be changed to the state of producing soft water, so that the entire system is always in the state of producing soft water and can continuously produce soft water.

[0044] In one embodiment, in step S1, after obtaining the water production instruction, the number of opened resin tanks is determined according to the water production requirement, and at least one of the resin tanks is in a closed soft water production state.

[0045] The water consumption is determined according to the user's back-end soft water usage scenario. For example, when washing clothes, the water consumption is large, so multiple resin tanks can be turned on. Of course, in order to ensure that the entire soft water system does not have all resin tanks in a state where they cannot produce soft water, at least one resin tank is in a closed soft water state during the soft water production stage.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
