Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a soft water water heater. Background Technology
[0002] A water heater is a device that uses various physical principles to raise the temperature of cold water to produce hot water within a certain time. Based on different principles, they can be divided into electric water heaters, gas water heaters, solar water heaters, etc. Currently, with the improvement of people's living standards, people's requirements for daily water use are also increasing. Due to regional factors, water quality varies greatly across the country, and water resources differ significantly. In most areas, the water quality is hard. Prolonged use of hard water can cause dry, rough skin and accelerated aging. Therefore, the demand for soft water is constantly rising. Soft water contains little or no soluble calcium and magnesium compounds. Using soft water can effectively inhibit fungi, delay skin aging, and prevent scale buildup after heating, offering numerous benefits to daily life.
[0003] Based on this, water softening water heaters that integrate water softening components with water heater components have emerged on the market. These water softening components are equipped with a brine tank to regenerate the water softening resin after prolonged use, when its adsorption capacity decreases. The brine tank typically contains inlet and outlet pipes, a brine valve, and a brine box to dissolve water softening salts and form a saturated brine, which is then transported to the water softening component to regenerate the resin. However, the existing internal structure of the brine tank is poorly designed. This not only causes multiple bends in the inlet and outlet pipes, affecting installation quality and lifespan, but also impacts the efficiency of water injection and saturated brine absorption. Furthermore, the cluttered layout increases the size of the brine tank, occupying significant space and limiting installation options. Utility Model Content
[0004] To address the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide a soft water water heater that reduces the volume of the salt tank by rationally arranging the internal structure of the salt tank, thereby avoiding restrictions on the installation location of the soft water water heater and avoiding multiple bends in water pipes and other pipelines, which helps to ensure the efficiency of water injection and saturated brine extraction.
[0005] This utility model provides a soft water water heater, including: a water heater body and a salt tank structure. The water heater body includes a shell, a soft water component and a heating component arranged side by side in the shell along a first direction, and the salt tank structure is detachably installed at the bottom of the water heater body.
[0006] The salt tank structure includes a salt tank body, which contains a salt valve, a salt box, and a water pipe. The salt valve and the salt box are arranged side by side along a first direction. The salt valve and the water pipe are both located on one side inside the salt tank body, and the two ends of the salt valve are connected to the salt box and the water pipe, respectively. The water pipe extends out of the salt tank body to connect to the water inlet pipe and the soft water assembly.
[0007] In a preferred embodiment of the present invention, a salt valve cavity and a salt box cavity are arranged side by side along a first direction inside the salt tank body. The salt valve cavity is located on one side inside the salt tank body, and the salt valve and water pipe are connected in the salt valve cavity, with the water pipe extending out of the salt valve cavity. The salt box is located in the salt box cavity, and the salt valve cavity and the salt box cavity are connected to each other so that the salt valve and the salt box are connected.
[0008] In a preferred embodiment, in this utility model, at least two salt boxes are provided and arranged side by side along the first direction on the same side of the salt valve, and at least two salt boxes are provided inside the salt box cavity.
[0009] In a preferred embodiment, the number of salt box cavities in this invention is equal to the number of salt boxes, with at least two salt boxes disposed in corresponding salt box cavities, and each salt box cavity can be connected to a salt valve cavity so that each salt box is connected to a salt valve.
[0010] In a preferred embodiment, in this invention, the salt valve cavity and at least two salt box cavities are sequentially connected along a first direction, the salt box is placed in the corresponding salt box cavity, and the corresponding salt box is connected to the salt box cavity.
[0011] In a preferred embodiment of the present invention, the salt valve chamber and at least two salt box chambers are connected by pipelines, the salt box is placed in the corresponding salt box chamber, and the corresponding salt box is connected to the salt box chamber, or the salt box and the salt valve are connected by corresponding pipelines.
[0012] In a preferred embodiment of the present invention, the salt box is detachably installed inside the salt box cavity, and a guide structure and / or a fixing structure are provided between the salt box and the salt box cavity.
[0013] In a preferred embodiment of the present invention, a protective cover is provided at the end of the water pipe extending out of the salt tank body, and the end of the water pipe extending out of the salt tank body passes through the protective cover to connect the water inlet pipe and the soft water assembly.
[0014] In a preferred embodiment of the present invention, a protective plate is installed on the bottom and / or side of the salt tank body, and the protective plate is detachably connected to the salt tank body.
[0015] In a preferred embodiment, the heating assembly of this invention includes a burner and a heat exchanger. The burner is used to heat the heat exchanger. The heat exchanger is connected to an external water source and an external water outlet assembly through an inlet pipe and an outlet pipe, respectively, so that the water flowing into the heat exchanger from the inlet pipe absorbs heat and is discharged through the outlet pipe. The soft water assembly is located on the inlet pipe or the outlet pipe.
[0016] The soft water water heater provided by this utility model has the following technical effects:
[0017] The salt valve and salt box of the salt tank structure are arranged side-by-side along the first direction.

The salt valve connects the water pipe and salt box, enabling the dissolution of soft water salt into saturated brine by injecting water through the inlet pipe, and the delivery of the saturated brine to the soft water component to regenerate the soft water resin. This salt tank structure, through its rational layout, helps to reduce the volume of the salt tank and avoids occupying too much space. When the salt tank structure is installed at the bottom of the water heater body, it reduces restrictions on the installation location of the soft water water heater. Furthermore, because the salt valve and water pipe are positioned corresponding to the soft water component, multiple bends in the water pipe during installation are avoided, thus ensuring the installation quality and service life of the water pipe and guaranteeing the efficiency of water injection and saturated brine absorption.

[0024] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0025] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0027] See Figure 2 and 3 and combined Figure 1 This utility model provides a salt tank structure, including a salt tank body 1. The salt tank body 1 is provided with a salt valve 2, a salt box 3 and a water pipe 4. The salt valve 2 and the salt box 3 are arranged side by side along a first direction. The salt valve 2 and the water pipe 4 are both located on one side inside the salt tank body 1. The two ends of the salt valve 2 are respectively connected to the salt box 3 and the water pipe 4. The water pipe 4 extends out of the salt tank body 1 to connect to the water inlet pipe and the water softening component 6.
[0028] The brine tank body 1 houses the brine valve 2, brine box 3, and water pipe 4. The first port of the brine valve 2 connects to the brine box 3 and the water pipe 4. The water pipe 4 extends out of the brine tank body 1 and connects to the inlet pipe and the water softening assembly 6. The inlet pipe connects to an external water source. When water needs to be added, the external water source enters the water pipe 4 through the inlet pipe, then flows through the brine valve 2 into the brine box 3 to dissolve the softened salt and form saturated brine. The water softening assembly 6 contains softening resin. When the water softening assembly 6 processes water for an extended period, causing the resin's adsorption capacity to decrease, the saturated brine in the brine box 3 flows through the brine valve 2 into the water pipe 4, and then is transported to the water softening assembly 6 to regenerate the resin. Thus, water addition and saturated brine extraction can be achieved through a simple connection structure of the water pipe 4, brine valve 2, and brine box 3.
[0029] The water pipe 4 extends out of the brine tank body 1 and connects to the water inlet pipe and the soft water component 6. A valve structure needs to be set so that water injection and saturated brine extraction can be carried out separately and cannot be carried out simultaneously. The valve can be manually or electrically controlled.
[0030] Based on this, the salt valve 2 and salt box 3 of the salt tank structure are arranged side by side along the first direction. Both the salt valve 2 and the water pipe 4 are located on one side inside the salt tank body 1. The salt valve 2 connects the water pipe 4 and the salt box 3, enabling the dissolution of soft water salt into saturated brine by injecting water through the inlet pipe, and the delivery of the saturated brine to the soft water component 6 to regenerate the soft water resin. This salt tank structure, through its rational layout, helps to reduce the volume of the salt tank and avoids occupying a large space. When the salt tank structure is installed at the bottom of the water heater body, it reduces restrictions on the installation location of the soft water water heater. Simultaneously, since the salt valve 2 and water pipe 4 are positioned corresponding to the soft water component 6, multiple bends in the water pipe 4 during installation are avoided, thus ensuring the installation quality and service life of the water pipe 4, and guaranteeing the efficiency of water injection and saturated brine absorption.
[0031] Specifically, a salt valve chamber 11 and a salt box chamber 12 are arranged side-by-side along a first direction inside the salt tank body 1. The salt valve chamber 11 is located on one side inside the salt tank body 1. The salt valve 2 and the water pipe 4 are connected and located inside the salt valve chamber 11, with the water pipe 4 extending out of the salt valve chamber 11. The salt box 3 is located inside the salt box chamber 12. The salt valve chamber 11 and the salt box chamber 12 are connected to allow the salt valve 2 to be connected to the salt box 3. The salt valve chamber 11 has a top-opening structure to facilitate the extension of the water pipe 4.
[0032] The salt valve chamber 11 and the salt box chamber 12 can be directly connected, i.e., a connection port is opened in the cavity wall between them; or the salt valve chamber 11 and the salt box chamber 12 can be connected by a pipeline, i.e., a connecting pipeline is set at the opening of them. Regardless of the connection structure, when the salt box 3 is placed in the salt box chamber 12 and the salt valve 2 is placed in the salt valve chamber 11, the connection ports of the salt box 3 and the salt valve 2 can directly extend into the connection port or the corresponding opening. Alternatively, the connection port of the salt box 3 can be connected to the inner cavity of the salt box chamber 12, and the connection port of the salt valve 2 can be connected to the inner cavity of the salt valve chamber 11. In this case, it is necessary to ensure that the bottom wall and side wall of the salt box chamber 12 and the salt valve chamber 11 are both sealed structures.
[0033] At least two salt boxes 3 are arranged side-by-side along the first direction on the same side of the salt valve 2, and both salt boxes 3 are located within the salt box cavity 12. The arrangement of at least two salt boxes 3 side-by-side along the first direction on the same side of the salt valve 2 allows for various installation options for the salt boxes 3. For example, at least two salt boxes 3 can be installed within one or more salt box cavities 12. The dimensions of the salt boxes 3 can be the same or different, thus allowing for a rational layout of the salt box cavities 12 and the installation of the salt boxes 3 to maximize space utilization.
[0034] A preferred design is that the number of salt box cavities 12 is equal to the number of salt boxes 3, with at least two salt boxes 3 housed in corresponding salt box cavities 12. Each salt box cavity 12 is connected to a salt valve cavity 11 so that each salt box 3 is connected to a salt valve 2. Each salt box 3 is placed in a corresponding salt box cavity 12, facilitating installation and ensuring the orderly placement of the salt boxes 3.
[0035] Based on this, the salt valve chamber 11 and at least two salt box chambers 12 are sequentially connected along the first direction. Salt boxes 3 are placed within their respective salt box chambers 12, and the corresponding salt boxes 3 are connected to their respective salt box chambers 12. The salt valve chamber 11 and salt box chambers 12 are sequentially connected via their chamber walls, eliminating the need for piping and further reducing the volume of the salt tank. In this structure, the connection port of the salt box 3 is connected to the inner cavity of the salt box chamber 12, and the connection port of the salt valve 2 is connected to the inner cavity of the salt valve chamber 11. In this case, it is necessary to ensure that the bottom and side walls of both the salt box chamber 12 and the salt valve chamber 11 are sealed. Alternatively, the salt valve 2 and salt box 3 can also be directly inserted into the connection ports of the chamber walls, allowing water injection and saturated brine extraction to flow directly into the salt valve 2 and salt box 3 without entering the salt valve chamber 11 and salt box chamber 12. The salt valve chamber 11 and salt box chamber 12 then serve only as accommodating spaces for the salt valve 2 and salt box 3.
[0036] Alternatively, the salt valve chamber 11 and at least two salt box chambers 12 are all connected by pipelines, with the salt box 3 placed in the corresponding salt box chamber 12 and connected to the salt box chamber 12. Alternatively, the salt box 3 and the salt valve 2 are connected by corresponding pipelines. The pipelines corresponding to the salt valve chamber 11 and at least two salt box chambers 12 have openings. When the salt box 3 is placed in the salt box chamber 12 and the salt valve 2 is placed in the salt valve chamber 11, the connection ports of the salt box 3 and the salt valve 2 can directly extend into the corresponding openings. Alternatively, the connection port of the salt box 3 is connected to the inner cavity of the corresponding salt box chamber 12, and the connection port of the salt valve 2 is connected to the inner cavity of the salt valve chamber 11. In this case, it is necessary to ensure that the bottom and side walls of the salt box chamber 12 and the salt valve chamber 11 are sealed structures.
[0037] The salt box 3 is detachably installed inside the salt box cavity 12, and a guide structure 121 and / or a fixing structure 122 are provided between the salt box 3 and the salt box cavity 12. The detachable installation of the salt box 3 allows it to be removed to replenish soft water salt when the salt level is low. The detachable installation of the salt box 3 can be achieved by creating an opening in the side wall or top of the salt box cavity 12. The specific location of the opening is determined according to structural design requirements, ensuring that there is no risk of leakage.
[0038] The guiding structure 121 can be a guide rail, guide groove, or other structure to facilitate the assembly and disassembly of the salt box 3. The fixing structure 122 can be a snap-fit structure or other structure to ensure that the salt box 3 is securely installed in the corresponding salt box cavity 12, preventing the salt box 3 from moving and affecting the stable installation of the salt box structure and / or causing water leakage.
[0039] Furthermore, a protective cover 5 is provided at the end of the water pipe 4 extending out of the salt tank body 1. The end of the water pipe 4 extending out of the salt tank body 1 passes through the protective cover 5 to connect the water inlet pipe and the water softener component 6. Since the water pipe 4 connects to the water inlet pipe and the water softener component 6 after extending out of the salt tank body 1, it essentially extends into the water heater body. The internal components of the water heater body are complex to install. If there is a collision with the water pipe 4, it may cause the water pipe 4 to deform or be damaged. The protective cover 5 can protect the end of the water pipe 4 extending out of the salt tank body 1.
[0040] In addition, a protective plate 8 is installed on the bottom and / or side of the salt tank body 1, and the protective plate 8 is detachably connected to the salt tank body 1. The protective plate 8 can be detachably installed on the bottom and / or side of the salt tank body 1 through a snap-fit structure, screw structure, riveting structure, etc., which helps to improve the structural strength of the salt tank structure and protect the salt tank body 1.
[0041] See Figure 1 and combined Figure 2 and Figure 3 The present invention also provides a soft water water heater, comprising: a water heater body and the above-mentioned salt tank structure. The water heater body includes a shell 9, a soft water component 6 and a heating component 7 arranged side by side in the shell 9 along a first direction. The salt tank structure is detachably installed at the bottom of the water heater body, and the salt valve 2 and the water pipe 4 are arranged corresponding to the soft water component 6. The water pipe 4 passes through the shell 9 to connect the water inlet pipe and the soft water component 6.
[0042] The inlet pipe is also connected to the water softening unit 6, allowing external water to be directly introduced into the water softening unit 6 for treatment with water softening resin to obtain soft water for heating by the heating unit 7. When water needs to be added, external water enters the water pipe 4 through the inlet pipe, and then flows into the salt box 3 through the salt valve 2 to dissolve the water softening salt and form saturated brine. When the water softening unit 6 processes water for a long time, causing the water softening resin's adsorption capacity to decrease, the saturated brine in the salt box 3 flows into the water pipe 4 through the salt valve 2, and then is transported to the water softening unit 6 to regenerate the water softening resin. In this way, the water softening unit 6 can directly treat external water to obtain soft water, and when the water softening resin's adsorption capacity decreases, water can be added and saturated brine can be drawn in through the simple connection structure of the water pipe 4, salt valve 2, and salt box 3 to regenerate the water softening resin.
[0043] Because of its compact size, the brine tank structure, when installed at the bottom of the water heater body, helps reduce the overall volume of the soft water water heater, thus lessening the limitations on its installation location. Simultaneously, since the brine valve 2 and water pipe 4 are positioned corresponding to the soft water component 6 within the water heater body, multiple bends in the water pipe 4 during installation are avoided, ensuring the installation quality and lifespan of the water pipe 4. This guarantees the efficiency of water injection and saturated brine absorption, thereby ensuring the regeneration effect of the soft water resin.
[0044] See Figure 4The heating assembly 7 includes a burner 71 and a heat exchanger 72. The burner 71 heats the heat exchanger 72. The heat exchanger 72 is connected to an external water source and an external water outlet assembly via an inlet pipe 73 and an outlet pipe 74, respectively, so that the water flowing into the heat exchanger 72 from the inlet pipe 73 absorbs heat and is then discharged through the outlet pipe 74. A water softening assembly 6 is installed on either the inlet pipe 73 or the outlet pipe 74. When the water softening assembly 6 is installed on the inlet pipe 73, it is used to soften the raw water from the external water source to obtain soft water, which is then heated by the heating assembly 7. When the water softening assembly 6 is installed on the outlet pipe 74, it is used to soften the raw water heated by the heating assembly 7.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
