Abstract

This application proposes a water softener, comprising: a housing having a first receiving cavity for holding brine; a resin tank vertically disposed within the first receiving cavity for softening hard water; and a valve control assembly disposed within the first receiving cavity for controlling the on / off connection between the first receiving cavity and the resin tank, and for controlling the on / off connection between the resin tank and an external water supply device, wherein the valve control assembly and the resin tank are arranged side-by-side along the length of the housing. This design achieves full utilization of the horizontal space of the housing without increasing its length, improving the utilization rate of the horizontal space and avoiding excessive occupation of the vertical space of the housing. This significantly reduces the overall height of the water softener, making it smaller and more suitable for miniaturized design.

Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a water softener. Background Technology

[0002] A water softener is a highly efficient water treatment device that effectively solves problems such as limescale and soap scum caused by hard water by removing calcium and magnesium ions (i.e., hardness ions) from the water. It is widely used in households, commercial and industrial fields.

[0003] Currently, water softeners on the market mainly consist of a tank, a resin tank, and a valve control assembly. The tank has a first receiving cavity for brine. The resin tank is located within the first receiving cavity and contains ion exchange resin, which adsorbs calcium and magnesium ions in the water and releases sodium ions, thereby softening the water. The valve control assembly is located within the first receiving cavity and above the resin tank. It controls the connection between the first receiving cavity and the resin tank, as well as between the resin tank and an external water supply device, to regulate the softening and regeneration process and ensure efficient and stable operation of the equipment. Specifically, during the softening stage: hard water is input into the resin tank via the valve control assembly, flows through the ion exchange resin, where calcium and magnesium ions are adsorbed, and sodium ions are released, forming soft water. The soft water is then output through a piston-type multi-way valve. During the regeneration stage: when the ion exchange resin is saturated, the regeneration program is initiated. Brine from the first receiving cavity is input into the resin tank via the valve control assembly to flush the ion exchange resin, displacing the adsorbed calcium and magnesium ions and rinsing away residual wastewater, restoring the ion exchange resin's softening capacity. Although the aforementioned water softeners can efficiently soften hard water, the valve control components are located on top of the resin tank, which takes up too much space in the tank, resulting in a large overall size of the water softener.

[0049] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0050] See Figures 1-5 This invention illustrates a preferred embodiment of a water softener, comprising:

[0051] Box 1, box 1 has a first receiving cavity, the first receiving cavity is used to hold brine;

[0052] Resin tank 2, vertically disposed within the first receiving cavity, is used to soften hard water; and

[0053] Valve control component 3 is located in the first receiving cavity. Valve control component 3 is used to control the opening and closing of the first receiving cavity and the resin tank 2 to ensure that the resin in the resin tank 2 can be regenerated, that is, to realize the resin regeneration function. Valve control component 3 is also used to control the opening and closing of the resin tank 2 and the external water supply device to ensure that the resin tank 2 can soften hard water, that is, to realize the hard water softening function. In this way, the brine supply, resin regeneration and softening process are centrally managed by valve control component 3 to ensure softening and regeneration efficiency. Valve control component 3 and resin tank 2 are arranged side by side along the length of the box body 1.

[0054] The water softener of this utility model, by placing the valve control component 3 in the first receiving cavity and arranging the valve control component 3 and the resin tank 2 side by side along the length of the housing 1, makes the arrangement of the resin tank 2 and the valve control component 3 more reasonable and compact, reducing redundant space occupation. At the same time, without increasing the length of the housing 1, it makes full use of the horizontal space of the housing 1, improves the utilization rate of the horizontal space of the housing 1, avoids the problem of excessive occupation of the height space of the housing 1, thereby significantly reducing the overall height of the water softener, making the overall volume of the water softener smaller, and more conducive to the miniaturization of the water softener.

[0055] See Figures 1-2 In one embodiment, the housing 1 includes:

[0056] Salt tank 11, salt tank 11 having a first cavity 111 for containing brine; and

[0057] Top cover 12 is located on top of salt tank 11. Top cover 12 covers the top opening of first cavity 111. Top cover 12 has second cavity 1211. Second cavity 1211 and first cavity 111 form first receiving cavity.

[0058] The lower parts of the resin tank 2 and the valve control assembly 3 are both located in the first cavity 111, while the top of the resin tank 2, the upper part of the valve control assembly 3, and the connecting pipe between the valve control assembly 3 and the resin tank 2 are all located in the second cavity 1211. By designing the housing 1 as a separate combination structure of the brine tank 11 and the top cover 12, the resin tank 2 and the valve control assembly 3 can extend into different cavities, making full use of the height space of the housing 1, thereby effectively reducing the overall volume of the water softener. Specifically, the lower parts of the resin tank 2 and the valve control assembly 3 are both located in the first cavity 111 of the brine tank 11, while the top of the resin tank 2, the upper part of the valve control assembly 3, and the connecting pipe are all integrated into the second cavity 1211 of the top cover 12. This design not only optimizes the effective volume utilization rate of the brine tank 11 but also improves the space utilization efficiency of the top cover 12, avoiding structural redundancy. Furthermore, the split design of the housing 1 makes the installation and maintenance of the resin tank 2 and the valve control assembly 3 more convenient, reducing production and operation costs. In terms of functional layout, the first chamber 111 is mainly used for brine storage, while the second chamber 1211 centrally houses the upper part of the valve control assembly 3 and the piping system, resulting in a more rational distribution of water, salt, and the valve control assembly 3, reducing mutual interference and improving operational stability. Additionally, this structure has good scalability, allowing for flexible adjustment of the size ratio of the salt tank 11 and the top cover 12 according to actual needs, adapting to different capacity applications of the housing 1 and meeting diverse user requirements.

[0059] In one embodiment, the valve control assembly 3 includes:

[0060] Salt valve 31, wherein the salt valve 31 is vertically disposed in the first cavity 111, and the salt valve 31 is connected to the first cavity 111; and

[0061] A piston-type multi-way valve 32 is located above the salt valve 31. The piston-type multi-way valve 32 is used to control the on / off state of the salt valve 31 and the resin tank 2, and to control the on / off state of the resin tank 2 and the external water supply device. The lower part of the piston-type multi-way valve 32 is located in the first cavity 111, and the upper part of the piston-type multi-way valve 32 is located in the second cavity 1211. The connecting pipe between the piston-type multi-way valve 32 and the resin tank 2 is located in the second cavity 1211. The length direction of the piston-type multi-way valve 32 is parallel to the width direction of the housing 1. Thus, by vertically placing the salt valve 31 in the first chamber 111 and directly connecting it to the first chamber 111, the piston-type multi-way valve 32 is installed across the first chamber 111 and the second chamber 1211, parallel to the width direction of the housing 1. The piston-type multi-way valve 32 centrally manages the on / off state of the salt valve 31 and the resin tank 2, as well as the connection between the resin tank 2 and the external water supply. At the same time, the connecting pipeline between the piston-type multi-way valve 32 and the resin tank 2 is integrated into the second chamber 1211, which optimizes the space utilization and improves the integration and ease of operation of the system control.

[0062] See Figures 1-5 In one embodiment, the top cover 12 includes:

[0063] The main cover 121 is located on top of the salt tank 11, covering the top opening of the first cavity 111. The main cover 121 has a second cavity 1211 and a salt inlet 1212, which connects directly to the first cavity 111 to prevent salt spillage and maintain equipment cleanliness.

[0064] The salt filling cap 122 is slidably mounted on the main cover 121. The salt filling cap 122 has an open state and a closed state. In the open state, the salt filling port 1212 is open; in the closed state, the salt filling port 1212 is closed. The salt filling cap 122 can be moved to switch between the open and closed states. Thus, by setting up the slidable salt filling cap 122, users can easily switch the open / closed state of the salt filling port 1212 for rapid salt addition, improving ease of use. The closed state of the salt filling cap 122 effectively seals the salt filling port 1212, preventing foreign objects from entering or brine from evaporating, thereby ensuring stable water quality. At the same time, the design of requiring active operation to open the salt filling cap 122 avoids accidental opening that could lead to contamination of the tank 1 or water evaporation. Furthermore, the structure of integrating the salt filling cap 122 onto the main cover 121 not only avoids additional space occupation, keeping the top cover 12 clean, but its separate design also facilitates individual disassembly, cleaning, or replacement, effectively reducing maintenance costs. Furthermore, compared to the flip-type design, the sliding salt cap 122 has a significant space advantage—it only requires horizontal movement without the need for a flip radius, making it particularly suitable for installation environments with limited space and expanding the adaptability of water softeners to different installation scenarios; the user experience is better, as the linear push-pull motion with one hand is less strenuous than the flip action, especially convenient for operation at heights; cleaning and maintenance are simpler, as the seamless sliding structure avoids the problem of salt scale buildup at the flip hinge; and the appearance is cleaner, with the salt cap 122 and the top cover 12 completely flush and seamless when closed, greatly improving the overall aesthetics of the product.

[0065] See Figures 3-4 In one embodiment, the main cover 121 is provided with a first connecting component 1213, and the salt-adding cover 122 is provided with a second connecting component 1221. When the salt-adding cover 122 is in the closed state, the second connecting component 1221 is detachably connected to the first connecting component 1213 to restrict the salt-adding cover 122 to the closed state. Thus, in the closed state of the salt-adding cover 122, the detachable connection between the first connecting component 1213 and the second connecting component 1221 ensures the stable closure of the salt-adding cover 122, preventing accidental opening that could lead to contamination of the housing 1 or evaporation of brine, while retaining the convenient detachable feature for easy salt-adding operations and equipment maintenance. This connection structure is simple and reliable, allowing for the fixing and releasing of the salt-adding cover 122 without complex operations, greatly improving ease of use. Simultaneously, this modular connection method facilitates individual component replacement, effectively reducing maintenance costs and extending product lifespan.

[0066] In one embodiment, both the first connecting component 1213 and the second connecting component 1221 are magnetic components, allowing them to be connected together magnetically. This magnetic connection design ensures that the first connecting component 1213 and the second connecting component 1221 automatically adhere and lock when the salt cap 122 is closed. This guarantees reliable sealing, preventing contamination of the container 1 and evaporation of brine, while also enabling easy one-handed opening and closing. The magnetic connection eliminates the need for complex structures like mechanical clips, simplifying the opening and closing action and significantly improving the user experience. It also avoids the problems of easy wear and salt jamming associated with traditional mechanical connectors, resulting in a longer service life and lower maintenance costs. Furthermore, this design facilitates quick disassembly, cleaning, and maintenance. The magnetic force can be adjusted as needed, ensuring both a secure closure and smooth opening and closing. The overall structure is simple, aesthetically pleasing, and highly practical.

[0067] Of course, in other embodiments, the first connecting component 1213 and the second connecting component 1221 can both be snap-fit ​​structures, so that the first connecting component 1213 and the second connecting component 1221 are connected together by snap-fit, which can also reliably keep the salt cap 122 in the closed state.

[0068] See Figures 3-4 In one embodiment, the salt inlet 1212 is located on the top of the main cover 121. Correspondingly, the salt cover 122 is slidably disposed on the top of the main cover 121. In this way, the salt cover 122 can avoid occupying additional space on the side or front of the water softener, making the overall layout more compact.

[0069] See Figures 3-4 In one embodiment, the main cover 121 is provided with at least two guide portions 1214, which are respectively placed on both sides of the salt filling port 1212 along the sliding direction of the salt filling cover 122.

[0070] The salt cap 122 has at least two guide grooves 1222, each guide groove 1222 being slidably engaged with a corresponding guide part 1214. By providing a precise sliding engagement structure between the guide parts 1214 on both sides of the salt inlet 1212 of the main cap body 122 and the guide grooves 1222 of the salt cap 122, smooth guidance and precise positioning of the salt cap 122 during opening and closing are achieved, effectively preventing the salt cap 122 from shifting or jamming. The dual-guide design ensures balanced force on the salt cap 122 during sliding, avoiding unilateral wear and significantly extending its service life. The fit clearance between the guide part 1214 and the guide groove 1222 can be precisely controlled, ensuring smooth sliding while effectively preventing salt particles from entering and affecting sliding performance. This structure is simple and reliable, achieving stable sliding of the salt cap 122 without additional complex mechanisms, while also facilitating disassembly and maintenance. The overall design balances operational reliability, durability, and ease of maintenance.

[0071] See Figures 1-2 In one embodiment, when the salt cap 122 is in the closed state, the salt cap 122 covers the guide portion 1214 to hide the guide portion 1214 and the guide groove 1222, so that the appearance of the water softener remains flat and the exposed guide portion 1214 is avoided from affecting the aesthetics.

[0072] See Figure 2 and Figure 5 In one embodiment, the housing 1 further includes:

[0073] The supporting shell 13 is provided with a first limiting part 131, a second limiting part 132 and a first supporting part 133;

[0074] The first limiting part 131 surrounds the first support part 133 and the second limiting part 132. The first limiting part 131 is provided on the top of the salt tank 11, and the top cover 12 is provided on the top of the first limiting part 131.

[0075] The second limiting part 132 is provided around the outer side wall of the resin tank 2, and the second limiting part 132 abuts against the outer side wall of the resin tank 2 to restrict the vertical movement of the resin tank 2. The second limiting part 132 has a clearance opening 1321, which extends through the second limiting part 132 both above and below. The clearance opening 1321 is for the top of the resin tank 2 to pass through.

[0076] At least a portion of the first support portion 133 is located within the first cavity 111, and the first support portion 133 supports the valve control assembly 3. The supporting shell 13 integrates a first limiting part 131, a second limiting part 132, and a first supporting part 133. The first limiting part 131 serves as a transitional connector between the salt tank 11 and the top cover 12, ensuring precise positioning of both and enhancing the overall structural stability. The second limiting part 132, through its wraparound design and the avoidance port 1321, effectively restricts the vertical displacement of the resin tank 2 while ensuring the freedom of its top installation, preventing misalignment caused by operational vibration. The first supporting part 133 provides stable support for the valve control assembly 3 within the first cavity 111, making the core component layout more compact and reasonable. This integrated supporting shell 13 structure, through its layered limiting design, achieves coordinated fixation of the tank 1, resin tank 2, and valve control assembly 3 within a limited space, improving the operational reliability of the water softener and simplifying the assembly process. At the same time, the through design of the avoidance port 1321 facilitates the installation and maintenance of the resin tank 2. The overall structure combines functionality and process economy.

[0077] See Figure 5In one embodiment, the first support portion 133 has a third receiving cavity 1331, which extends through the top of the first support portion 133 and accommodates the lower part of the piston-type multi-way valve 32 in the valve control assembly 3. Thus, the third receiving cavity 1331 provides precise positioning and stable support for the piston-type multi-way valve 32, effectively preventing vibration displacement during operation. Secondly, the through-type design of the third receiving cavity 1331 facilitates the vertical installation and maintenance of the piston-type multi-way valve 32 and ensures smooth connection between the piston-type multi-way valve 32 and the upper assembly. Furthermore, this integrated support shell 13 structure achieves complete encapsulation and fixation of the piston-type multi-way valve 32 within a limited space, significantly improving the stability of the water softener's operation, while simplifying the assembly process, reducing production costs, and combining structural strength with operational convenience, making the internal layout of the water softener more compact and rational.

[0078] See Figure 2 and Figure 5 In one embodiment, the supporting shell 13 is further provided with a second support part 134, which is located inside the first cavity 111. The second support part 134 and the first support part 133 are respectively placed on both sides of the second limiting part 132 along the length direction of the box 1, and the second support part 134 abuts against the inner wall of the first cavity 111. Thus, by abutting against the inner wall of the first cavity 111, the second support part 134 forms a bidirectional support structure, which not only enhances the overall rigidity of the salt tank 11 and restricts its deformation, but also significantly enhances the overall rigidity of the supporting shell 13, effectively dispersing the working vibration of the piston-type multi-way valve 32 and the salt valve 31. In addition, the second support part 134 and the first support part 133 work together to form a stable triangular support system, preventing the resin tank 2 from undergoing lateral displacement during operation. At the same time, since the second support part 134 and the first support part 133 are respectively placed on both sides of the second limiting part 132 along the length of the tank 1, the space utilization rate inside the first cavity 111 is optimized, making the positioning of each functional component more accurate and the installation more convenient. Furthermore, the addition of the second support part 134 significantly improves the operational stability of the core components and extends the service life of the equipment without affecting the compactness of the equipment.

[0079] In one embodiment, the second support portion 134 is located directly below the salt inlet 1212. The second support portion 134 has a clearance hole 1341 that extends through the second support portion 134 both vertically and horizontally, connecting the salt inlet 1212 and the first cavity 111. This creates a direct channel between the salt inlet 1212 and the first cavity, allowing salt particles to fall directly into the first cavity 111 during salting, preventing salt accumulation or spillage. Furthermore, while maintaining structural strength, the second support portion 134, through the clearance hole 1341, also considers functional requirements, providing convenience for salting while ensuring effective support for the salt tank 11. Additionally, this integrated design simplifies the salting path, improves salting efficiency, and maintains the integrity and stability of the supporting shell 13, ensuring both structural strength and convenient salting functionality during long-term use, achieving the optimal balance between structural performance and ease of use.

[0080] In one embodiment, the first limiting part 131 is connected to the salt tank 11 by fasteners, which not only ensures a stable connection between the supporting shell 13 and the salt tank 11, effectively improving the overall structural strength and vibration resistance, but also facilitates quick disassembly during subsequent maintenance. This connection method has advantages such as precise installation positioning, reliable connection, and good durability. The connection strength can be adjusted by selecting the appropriate type and number of fasteners according to different working conditions. At the same time, it avoids the maintenance difficulties caused by irreversible connection methods such as bonding. While ensuring structural stability, it also takes into account the ease of assembly and maintenance, and optimizes the long-term reliable operation of the equipment and the maintenance cost throughout the entire life cycle.

[0081] Of course, in other embodiments, the first limiting part 131 can also be connected to the salt tank 11 by a snap-fit ​​mechanism.

[0082] In one embodiment, the main cover 121 is connected to the first limiting part 131 by a snap-fit ​​mechanism. This snap-fit ​​connection quickly fixes the main cover 121 to the first limiting part 131, achieving the dual advantages of convenient assembly and reliable connection. Furthermore, the snap-fit ​​structure allows for installation and disassembly without additional tools, significantly improving production efficiency and maintenance convenience.

[0083] Of course, in other embodiments, the main cover 121 can also be connected to the first limiting part 131 by fasteners.

[0084] See Figures 4-5 In one embodiment, the water softener further includes:

[0085] The control circuit board (not shown in the figure) is located on the housing 1. The control circuit board is electrically connected to the valve control assembly 3, that is, the control circuit board is electrically connected to the salt valve 31 and the piston multi-way valve 32.

[0086] Battery 4 is located on the housing 1 and is electrically connected to the control circuit board. Battery 4 is used to supply power to the control circuit board when the water softener is powered off. In this way, when the external power supply is interrupted, battery 4 can automatically switch to power the control circuit board, ensuring that the resin regeneration program can still be fully executed in the event of an unexpected power outage. This ensures that the water softener can immediately resume normal water production function after the power is restored, avoiding resin failure caused by regeneration interruption. At the same time, the uninterrupted power supply maintains the storage of key system parameters, achieving dual protection against power outages and continuous operation.

[0087] In one embodiment, the control circuit board is located inside the second cavity 1211, and the battery 4 is located inside the top cover 12. Thus, placing the control circuit board in the second cavity 1211 provides structural protection from the top cover 12, preventing moisture corrosion and facilitating heat dissipation and maintenance. The top-mounted design of the battery 4 shortens the power supply distance to the control circuit board, improving energy efficiency, and also fully utilizes the unused space of the top cover 12 to optimize the overall layout.

[0088] See Figures 4-5 In one embodiment, the main cover 121 also has a second receiving cavity 141, which is connected to the second cavity 1211. The control circuit board is disposed in the second cavity 1211, and the second receiving cavity 141 accommodates the storage battery 4.

[0089] Top cover 12 also includes:

[0090] Battery cover 15, battery cover 15 is disposed on main cover 121, battery cover 15 covers the opening of second receiving cavity 141; and

[0091] A sealing component 16 is disposed on the main cover 121, surrounding the opening of the second receiving cavity 141, and sandwiched between the main cover 121 and the battery cover 15. This separate arrangement of the control circuit board and the battery 4 ensures both electrical safety distance and facilitates centralized management; the battery cover 15, together with the surrounding sealing component 16, forms a waterproof and dustproof sealed space, effectively protecting the battery 4 from environmental corrosion.

[0092] See Figure 5 In one embodiment, the top cover 12 further includes:

[0093] The battery box 14 is disposed on the main cover 121 and has the aforementioned second receiving cavity 141. Integrating the battery box 14 into the main cover 121 forms a dedicated second receiving cavity 141, providing an independent protective space for the battery 4, which effectively isolates electrical risks and facilitates centralized management.

[0094] In one embodiment, the battery cover 15 can be connected to the battery box 14 by a snap-fit ​​mechanism. Of course, the battery cover 15 can also be connected to the battery box 14 by fasteners.
