Description

Technical Field

[0001] This invention relates to the field of water softener technology, and specifically provides a split-type water softener. Background Technology

[0002] As people's living standards continue to improve, they are paying more attention to the quality of their daily water use. Water softeners, used to remove calcium and magnesium ions from water, have become an increasingly common household appliance. Water softeners mainly come in two types: split-type and integrated-type. In a split-type water softener, the main unit and the brine tank are separate. The brine tank is connected to the main unit via a connecting pipe to provide the brine solution for regenerating the ion exchange resin in the main unit's resin tank. In an integrated-type water softener, the main unit and the brine tank are integrated. The resin tank of the main unit is located inside the brine tank, and the space between the inner wall of the brine tank and the outer wall of the resin tank constitutes the salt-containing space.

[0003] Because the main unit and brine tank are separate, existing split-type water softeners require separate packaging, using more packaging materials and occupying more space during storage and transportation, resulting in higher storage and transportation costs. Integrated water softeners combine the main unit and brine tank, with the resin tank of the main unit located inside the brine tank. Compared to split-type water softeners, this reduces the overall size, requires less packaging material, and occupies less space during storage and transportation, thus lowering storage and transportation costs. However, by placing the resin tank inside the brine tank, the integrated water softener reduces the salt capacity of the brine tank, causing the salt to be used up more quickly. Users often don't easily notice when the salt in the tank is depleted, which can lead to situations where the ion exchange resin in the resin tank is not actually regenerated after the water softener performs a regeneration operation, failing to effectively soften the water. Even if users frequently check the salt level in the brine tank and add salt promptly when it's low, while this prevents the ion exchange resin in the resin tank from not actually being regenerated after the integrated water softener's regeneration process, it still requires frequent checks and increases the frequency of salt additions, resulting in a poor user experience. Water softeners are typically installed in confined spaces under cabinets or within small cabinet enclosures. Frequently checking the salt level in the brine tank within these limited spaces and adding salt regularly further negatively impacts the user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, the problem that existing water softeners cannot balance the costs of packaging, storage, and transportation with a good user experience.

[0006] The present invention provides a split-type water softener, comprising: a resin tank; a housing for installing a water circuit switching component, wherein the bottom of the housing is provided with a mounting part for fixing the resin tank; and a salt tank, the salt tank comprising a box body having a top opening, the projection of the top opening on the horizontal plane being able to completely cover the projection of the resin tank on the horizontal plane.

[0007] In the preferred embodiment of the above-mentioned split-type water softener, one end of the resin tank is fixed to the bottom of the housing, and the other end of the resin tank extends in a direction perpendicular to the bottom surface of the housing. The depth of the inner cavity of the housing is greater than or equal to the height of the resin tank, and / or the width of the cavity of the housing is greater than or equal to the diameter of the resin tank.

[0008] In the preferred embodiment of the above-mentioned split-type water softener, a plug-in end is provided at the top opening, and a first fixed end is provided at the bottom of the casing. The housing can be plugged into the first fixed end through the plug-in end to fix the casing on the salt tank.

[0009] In the preferred embodiment of the above-mentioned split-type water softener, the thickness of the plug-in end is less than the thickness of the housing and forms a first step structure with the housing, and / or the thickness of the first fixed end is less than the thickness of the casing and forms a second step structure with the casing.

[0010] In the preferred embodiment of the above-mentioned split-type water softener, the plug-in end extends circumferentially along the top opening to form a first annular structure, and the first fixed end extends circumferentially along the bottom surface of the casing to form a second annular structure, so that when the box body is connected to the casing, one side of the first annular structure fits and connects with one side of the second annular structure.

[0011] In the preferred embodiment of the above-mentioned split-type water softener, the salt tank further includes a top cover that is detachably connected to the top opening.

[0012] In the preferred embodiment of the above-mentioned split-type water softener, the upper cover is provided with a mounting hole for avoiding the salt valve, so that when the upper cover is connected to the top opening, the salt valve extends out from the mounting hole.

[0013] In the preferred technical solution of the above-mentioned split-type water softener, a second fixed end is provided on one side of the top cover. The second fixed end is used to connect with the plug-in end. The second fixed end and the plug-in end are both stepped structures that cooperate with each other.

[0014] In the preferred embodiment of the above-mentioned split-type water softener, the salt tank is provided with a positioning part for positioning the salt valve and an installation space for accommodating the resin tank. The positioning part and the installation space are spaced apart from each other on the projection of the bottom surface of the salt tank, so that the resin tank and the salt valve can avoid each other when the housing is connected to the salt tank.

[0015] In the preferred embodiment of the above-mentioned split-type water softener, there are multiple mounting parts and multiple resin tanks, which are arranged side by side at the bottom of the casing and installed to the mounting parts one by one.

[0016] When the above technical solution is adopted, the split-type water softener includes: a resin tank; a housing for installing the water circuit switching component, wherein the bottom of the housing is provided with a mounting part for fixing the resin tank; and a brine tank, which includes a box with a top opening, the projection of the top opening on the horizontal plane being able to completely cover the projection of the resin tank on the horizontal plane.

[0017] With this design, when installed, the resin tank of the split-type water softener of this invention is located outside the brine tank. The internal space of the brine tank is not occupied by the resin tank. Compared with an integrated water softener with a brine tank of the same size, the brine tank has a larger salt holding capacity, allowing the water softener to remain unfilled for a longer period after a single salt addition, thus reducing the frequency of salt additions. When salt needs to be added to the brine tank, it is added through the large opening at the top of the tank, making it easier to add salt. Therefore, the split-type water softener of this invention requires less frequent salt additions during daily use, facilitating salt replenishment and optimizing the user experience. In the non-installation state (i.e., storage, transportation, etc.), the resin bucket is inserted into the box through the top opening, with at least a portion of the resin bucket located inside the salt tank. This utilizes the space within the box in the non-installation state, significantly reducing the overall volume of the split-type water softener compared to its installed state. This greatly reduces the space required for storage, transportation, and packaging, thus lowering costs and facilitating these processes. Therefore, the split-type water softener of this invention reduces packaging, storage, and transportation costs while ensuring a good user experience.

[0018] Preferably, the top opening is provided with a plug-in end, and the bottom of the housing is provided with a first fixed end. The housing can be plugged into the first fixed end through the plug-in end to fix the housing onto the salt tank.

[0019] With this setup, in the non-installed state, the casing is connected to the plug-in end on the salt tank via the first fixed end, thus fixing the casing to the salt tank. The relative fixation between the casing and the salt tank makes it easier to store, pack, and transport.

[0020] Preferably, the thickness of the plug-in end is less than the thickness of the housing and forms a first step structure with the housing, and / or the thickness of the first fixed end is less than the thickness of the casing and forms a second step structure with the casing.

[0021] This design facilitates the connection between the housing and the connector on the salt container body via the first fixed end when not in use, improving the efficiency of storage, handling, and packaging, and simplifying storage, handling, and transportation. Preferably, there are multiple mounting sections and resin tanks, with multiple resin tanks arranged side-by-side at the bottom of the housing and installed one-to-one with the mounting section.

[0022] With this setup, the total capacity of the resin tank to hold ion exchange resin can be significantly increased while maintaining a relatively constant footprint for the water softener. This reduces the frequency of resin regeneration operations, preventing high-frequency regeneration from taking up too much time and affecting the softening process, thus further optimizing the user experience.

[0032] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] It should be noted that in the description of the invention, terms such as "left" and "right," which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Based on the issue mentioned in the background art that existing water softeners cannot simultaneously address the costs of packaging, storage, and transportation while maintaining a good user experience, this invention provides a split-type water softener, comprising: a resin tank; a housing for installing a water circuit switching component, wherein the bottom of the housing is provided with a mounting part for fixing the resin tank; and a brine tank, the brine tank comprising a box body with a top opening, the projection of the top opening on the horizontal plane being able to completely cover the projection of the resin tank on the horizontal plane.

[0036] With this design, when installed, the resin tank of the split-type water softener of this invention is located outside the brine tank. The internal space of the brine tank is not occupied by the resin tank. Compared with an integrated water softener with a brine tank of the same size, the brine tank has a larger salt holding capacity, allowing the water softener to remain unfilled for a longer period after a single salt addition, thus reducing the frequency of salt additions. When salt needs to be added to the brine tank, it is added through the large opening at the top of the tank, making it easier to add salt. Therefore, the split-type water softener of this invention requires less frequent salt additions during daily use, facilitating salt replenishment and optimizing the user experience. In the non-installation state (i.e., storage, transportation, etc.), the resin bucket is inserted into the box through the top opening, with at least a portion of the resin bucket located inside the salt tank. This utilizes the space within the box in the non-installation state, significantly reducing the overall volume of the split-type water softener compared to its installed state. This also significantly reduces the space required for storage, transportation, and packaging, lowering costs and facilitating these processes. Therefore, the split-type water softener of this invention reduces packaging, storage, and transportation costs while ensuring a good user experience.

[0037] The following reference Figures 1 to 6 The present invention will now be described. Among other things, Figure 1 This is a schematic diagram of a split-type water softener according to an embodiment of the present invention in its installed state; Figure 2 yes Figure 1 A magnified view of part A in the middle; Figure 3 This is an exploded view of the brine tank of a split-type water softener according to an embodiment of the present invention; Figure 4 yes Figure 3 A magnified view of part B in the middle; Figure 5 This is an assembly diagram of the brine tank of a split-type water softener according to an embodiment of the present invention; Figure 6 This is a schematic diagram of a split-type water softener in the non-installed state according to an embodiment of the present invention.

[0038] like Figures 1 to 6 As shown, the split-type water softener includes a main unit 1 and a brine tank 2. The main unit 1 includes a cubic casing 11, a water circuit switching assembly (such as a six-way reversing valve, not shown in the figure) disposed within the casing 11, and two resin tanks 12 connected to the lower part of the casing 11. Figure 6As shown, the right-side side wall of the housing 11 is provided with an inlet 131, an outlet 132, a brine inlet 133, and a wastewater inlet 134, which are respectively connected to the first, second, third, and fourth interfaces of the water circuit switching component. The lower part of the housing 11 has two mounting portions (not shown) arranged along the length of the housing 11. The resin tank 12 is generally cylindrical, and the two resin tanks 12 are arranged below the housing 11 along the length of the housing 11, with each resin tank 12 correspondingly mounted to one of the two mounting portions. Specifically, the mounting portion includes a base plate of the housing 11, a through hole formed on the base plate, and a cylindrical structure extending downward from the edge of the through hole. The inner diameter of the cylindrical structure is the same as the outer diameter of the resin tank 12. Near the upper end, the side wall of the resin tank 12 has an annular rib coaxial with the resin tank 12. The portion of the resin barrel 12 below the annular rib passes through the cylindrical structure from top to bottom, with the lower surface of the annular rib abutting against the upper surface of the base plate of the housing 11. The mounting portion also includes multiple threaded holes on the upper surface of the base plate of the housing 11 and a clamping cap that fits the shape of the top of the resin barrel 12. Multiple locking holes are evenly distributed around the through holes on the base plate of the housing 11. The edge of the clamping cap has through holes corresponding to the threaded holes for a portion of the screw to pass through. The clamping cap covers the upper part of the resin barrel 12, and a portion of the screw passes through the through hole on the clamping cap and is screwed into the threaded hole on the base plate of the housing 11. Thus, the clamping cap and the base plate of the housing 11 clamp the annular rib on the resin barrel 12, thereby fixing the resin barrel 12 to the mounting portion at the bottom of the housing 11. Each resin tank 12 has a central tube extending from top to bottom (not shown in the figure). The upper ends of the central tubes of both resin tanks 12 are connected to the fifth interface of the water circuit switching component. The lower ends of the central tubes of both resin tanks 12 are connected to a water distributor (not shown in the figure). The two resin tanks 12 contain ion exchange resin (not shown in the figure). The upper ends of the two resin tanks 12 are each provided with a water inlet opening (not shown in the figure), and both openings are connected to the sixth interface of the water circuit switching component. A pipe connector is provided at the fifth interface of the water circuit switching component. A insertion hole is provided on one side of the pipe connector. The upper part of the resin tank 12 has a connecting pipe with an annular groove formed on its outer wall. The connecting pipe is inserted into the pipe connector of the water circuit switching component, and the insertion piece is inserted from the insertion hole and snapped into the annular groove on the connecting pipe, realizing the snap-fit ​​connection between the connecting pipe and the pipe connector.

[0039] like Figure 3As shown, the salt tank 2 includes a body 21 with a top opening 211 and a top cover 22 detachably connected to the top opening 211. The body 21 contains a salt valve 23, a positioning part for positioning the salt valve, and an installation space for accommodating resin tanks 12. The projections of the positioning part and the installation space onto the bottom surface of the body 21 are spaced apart, so that when the housing 11 is connected to the body 21, the resin tanks 12 and the salt valve 23 avoid each other. The salt valve 23 is connected to the salt suction port 133 via a connecting pipe (not shown in the figure). The projection of the top opening 211 onto the horizontal plane completely covers the projections of the two resin tanks 12 onto the horizontal plane, allowing the two resin tanks 12 to be inserted into the body 21 through the top opening 211. In this embodiment, specifically, the shape and size of the top opening 211 are the same as the cross-sectional size of the inner cavity of the box 21, the width of the inner cavity of the box 21 is equal to the diameter of the resin barrel 12, the length of the inner cavity of the box 21 is greater than the maximum distance between the outer walls of the two resin barrels 12, and the depth of the inner cavity of the box 21 is greater than the height of the resin barrel 12.

[0040] The bottom of the housing 11 is provided with a first fixed end, and the top opening 211 is provided with a plug-in end. The housing 21 can be plugged into the first fixed end through the plug-in end to fix the housing 11 to the housing 21. Figure 1 and Figure 2 As shown, the upper edge of the housing 21 forms a plug-in end, and the bottom surface of the housing 11 has a first annular area (not shown in the figure) that can abut against the top of the plug-in end. The inner area of ​​the inner ring of the first annular area extends downward into the second annular area close to the inner ring of the first annular area, and the first annular rib 111 forms the first fixed end of the bottom of the housing 11. The first annular rib 111 and the first annular area on the bottom surface of the housing 11 form a stepped structure.

[0041] The lower side of the top cover 22 is provided with a second fixing end, which is used for plugging and connecting with the plug-in end on the housing 21. For example... Figure 3 and Figure 4 As shown, the upper cover 22 includes a base plate 221 and a second annular rib 222 extending downward from the lower surface of the base plate 221. The shape and size of the periphery of the base plate 221 are the same as the shape and size of the upper outer ring of the housing 21. The shape and size of the outer ring of the second annular rib 222 are the same as the shape and size of the top opening 211. The second annular rib 222 forms a second fixed end located on the lower side of the upper cover 22. The base plate 221 is provided with a mounting hole 223 through which the upper end of the salt valve 23 protrudes, so that when the upper cover 22 is connected to the top opening 211, the upper end of the salt valve 23 protrudes from the mounting hole 223.

[0042] like Figure 1As shown, in the installed state, the salt tank 2 and the main unit 1 are placed side by side adjacent to each other in the left-right direction. The resin tank 12 is located outside the box body 21, and the top cover 22 is installed on the top of the box body 21. The second annular rib 222 is inserted into the top opening 211, and the outer ring of the second annular rib 222 transitions with the inner wall of the box body 21. The base plate 221 covers the top opening 211. The water inlet 131 is connected to a water source (such as a water storage tank, tap water pipe, etc.), the water outlet 132 is connected to a faucet, and the wastewater outlet is connected to a drain pipe (not shown in the figure).

[0043] The resin tank 12 is located outside the salt tank 2, and the internal space of the salt tank 2 is not occupied by the resin tank 12. Compared with an integrated water softener with a salt tank of the same size, the salt tank 2 has a larger salt holding capacity, allowing the water softener to remain unfilled for a longer period after a single salt addition, thus reducing the frequency of salt addition. Since the salt tank 2 includes a body 21 with a top opening 211 and a top cover 22 detachably connected to the top opening 211, and the shape and size of the top opening 211 are the same as the cross-sectional dimensions of the inner cavity of the body 21, when salt needs to be added to the salt tank 2, the top cover 22 can be removed to add salt through the top opening 211 of the body 21. The larger size of the top opening 211 of the body 21 makes it easier to add salt. Therefore, the split-type water softener of this invention requires less frequent salt addition during daily use, making it easier to add salt to the salt tank 2 and optimizing the user experience.

[0044] See Figure 6 In the non-installed state, the resin bucket 12 is inserted into the housing 21 through the top opening 211, with the outer wall of the resin bucket 12 fitting against the inner wall of the housing 21 (not shown in the figure). The housing 11 is located outside the housing 21. The edge of the top opening 211 of the housing 21 supports the first annular area at the bottom of the housing 11. The first annular rib 111 is inserted into the top opening 211, and the outer wall of the first annular rib 111 abuts against the inner wall of the housing 21, thus achieving a fixed connection between the housing 11 and the housing 21 and limiting their horizontal movement. The top cover 22 is stacked below the bottom plate of the housing 21.

[0045] The resin bucket 12 makes full use of the space inside the box 21, which greatly reduces the overall volume of the split water softener of the present invention when it is not installed, greatly reduces the space occupied by storage and transportation, and greatly reduces the packaging materials used, thereby reducing the cost of packaging, storage and transportation, and facilitating storage, packaging and transportation.

[0046] Therefore, the split-type water softener of the present invention reduces the costs of packaging, storage, and transportation, while ensuring a good user experience.

[0047] It should be noted that the lower surface of the substrate 221 extends downward to form a second annular rib 222. The shape and size of the outer ring of the second annular rib 222 are the same as the shape and size of the top opening 211. In the installed state, the second annular rib 222 is inserted into the top opening 211, and the outer ring of the second annular rib 222 transitions with the inner wall of the housing 21. The second annular rib 222 forms a second fixed end located on the lower side of the upper cover 22. This is only one specific arrangement, and it can be adjusted in actual applications, such as adjusting the outer ring of the second annular rib 222 with the housing. The inner wall of the cover 21 is press-fitted; or the lower surface of the substrate 221 extends downward to form a columnar boss, the shape and size of the side wall profile of the columnar boss are the same as the shape and size of the top opening 211, and the columnar boss forms a second fixed end located on the lower side of the cover 22; in the installed state, the columnar boss is inserted into the top opening 211, and the four sides of the columnar boss are transition-fitted or press-fitted with the inner wall of the housing 21; the top cover 22 and the housing 21 can also be connected by a claw and snap-fit ​​structure, or detachably connected by other suitable means. In addition, the substrate 221 is provided with a mounting hole 223 through which the upper end of the salt supply valve 23 passes, which is also a specific setting method. It can be adjusted in actual applications, such as providing a through hole on the side wall of the housing 21 through which the connecting pipe connecting the salt supply valve 23 and the salt suction port 133 passes. Furthermore, within the inner ring of the first annular region, a first annular rib 111 extends downward from the second annular region adjacent to the inner ring of the first annular region. The first annular rib 111 forms the first fixed end at the bottom of the housing 11. In the non-installed state, the first annular rib 111 is inserted into the top opening 211, and its outer wall abuts against the inner wall of the housing 21, thus achieving a fixed connection between the housing 11 and the housing 21, as well as limiting their horizontal movement. This is only one specific configuration; adjustments can be made in practical applications. For example, the inner ring of the first annular region can form a downwardly protruding columnar boss, which forms the housing 11. In the non-installed state, the first fixed end at the bottom has a columnar boss inserted into the top opening 211, with the four sides of the columnar boss abutting against the inner side wall of the housing 21, thus limiting the horizontal movement of the housing 11 and the housing 21; or, in the inner region of the first annular area, multiple downwardly extending baffles are evenly distributed in the second annular area near the inner ring of the first annular area, forming the first fixed end at the bottom of the housing 11. In the non-installed state, the multiple baffles are inserted into the top opening 211, with each baffle abutting against the inner side wall of the housing 21 closest to the inner wall of the housing, thus limiting the horizontal movement of the housing 11 and the housing 21.

[0048] It should also be noted that having two resin tanks 12 is a preferred configuration, but this can be adjusted in practice. For example, the number of resin tanks 12 can be one, three, or more. Alternatively, the resin tanks 12 can be cylindrical, which can also be adjusted in practice. For instance, the resin tanks can be cubic, with dimensions matching the size of the salt tank 2, so that the space inside the tank 21 can be utilized to the maximum extent when the resin tank is inserted. In another feasible embodiment, a single resin tank is used, with its shape matching the shape of the internal space of the tank 21. In the non-installed state, the area ratio of the resin tank and the inner cavity of the tank 21 at the same horizontal plane is not less than 90%. This significantly increases the total capacity of the ion exchange resin in the resin tank while maintaining a relatively constant space occupied by the water softener, thereby reducing the frequency of resin regeneration operations and avoiding the impact of high-frequency regeneration operations on water softening, further optimizing the user experience. Furthermore, in the non-installed state, the top cover 22 is stacked under the bottom plate of the housing 21. This is only one specific arrangement, and it can be adjusted in actual applications. For example, the top cover 22 can be stacked on the top of the housing 11 and glued to the outer or inner wall of the housing 21, or glued to the outer wall of the housing 11, or directly placed inside the housing 21, or inserted into the housing 11 by providing an insertion opening on the housing 11.

[0049] In another feasible embodiment, unlike the above embodiment, the plug-in end is a third annular rib located at the upper end of the housing 21. The thickness of the third annular rib is less than the thickness of the housing, and the outer wall of the third annular rib is flush with the side wall of the housing 21.

[0050] In the installed state, the top cover 22 is installed on the top of the housing 21, the second annular rib 222 is inserted into the third annular rib, the outer ring of the second annular rib 222 transitions with the inner wall of the third annular rib, and the base plate 221 covers the top opening 211.

[0051] In the non-installed state, the housing 11 is located outside the box 21. The upper surface of the third annular rib supports the first annular area at the bottom of the housing 11. The first annular rib 111 is inserted into the third annular rib. The outer side wall of the first annular rib 111 abuts against the inner side wall of the third annular rib, thereby achieving a fixed connection between the housing 11 and the box 21 and limiting their position in the horizontal direction.

[0052] In another feasible embodiment, the top cover 22 is not provided.

[0053] In another feasible embodiment, unlike the above embodiment, the host 1 is configured to have the same height as the salt tank 2.

[0054] Typically, water softeners are installed in cubic spaces. With this design, when the water softener of this invention is installed, the main unit 1 and the brine tank 2 are at the same height, allowing for more efficient use of the installation space.

[0055] Preferably, the main unit 1 is configured such that most of the casing 11 and the resin tank 12 can be placed inside the box 21. This further reduces the overall volume of the water softener of the present invention in the non-installation state, further reduces the space occupied by storage and transportation, further reduces the packaging materials used, further reduces the cost of packaging, storage and transportation, and facilitates storage, packaging and transportation.

[0056] In another feasible embodiment, unlike the above embodiment, the resin tank 12 is detachably connected to the lower part of the housing 11. The split-type water softener is equipped with a series of resin tanks 12 of different heights and a series of housings 21 of corresponding heights, so that the resin tanks 12 and housings 21 of corresponding heights can be selected according to the height of the installation space of the split-type water softener.

[0057] Since the installation space (such as under-sink space) for water softeners varies in different users' homes, the above-described configuration allows users to select resin tanks 12 and housings 21 of corresponding heights based on the height of their installation space, better meeting their needs. For water softener manufacturers, there's no need to produce multiple different models and specifications; they only need to manufacture a series of resin tanks 12 and housings 21 of varying heights. Compared to manufacturing different models and specifications, this results in relatively lower manufacturing costs.
