Description

Technical Field

[0001] The present invention relates to the technical field of water purification equipment, in particular to a water softener housing and a water softener. Background Art

[0002] As living standards improve, a variety of water softener products have emerged on the market. Water softeners use ion exchange resins to absorb calcium and magnesium ions in water, softening the water and reducing scale. When the exchange capacity of the exchange resin reaches saturation, it needs to be backwashed with salt water to exchange the calcium and magnesium ions adsorbed on the resin with sodium ions, allowing the resin to regain its softening ability.

[0003] The water softener housing is equipped with a salt inlet, through which salt is added to the interior. During product installation and user use, salt particles can accumulate in the softener housing, forming a mountainous pattern. This affects the salt loading capacity and the accuracy of the salt level detector, thus affecting the salt dissolution effect. To ensure that the salt particles are spread as evenly as possible within the salt tank, the user may cause salt particles to roll out of the water softener when shaking the salt tank, requiring additional cleaning work and affecting the user experience. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention provides a water softener housing that can reduce the possibility of salt particles rolling out of the water softener during the salt pouring process.

[0005] The present invention also provides a water softener.

[0006] The water softener housing according to the first embodiment of the present invention comprises:

[0007] salt box;

[0008] a middle frame, the middle frame having a first side and a second side opposite to each other and a first opening extending through the first side and the second side, the second side being connected to the top of the salt box, the first side having an annular concave surface surrounding the first opening, the height of the first opening relative to the salt box being less than the height of the annular concave surface relative to the salt box;

[0009] The grille assembly includes an outer frame, a plurality of channels for salt particles to pass through are formed in the outer frame, and the outer frame is arranged at the first opening so that the channels are connected to the interior of the salt box.

[0010] According to an embodiment of the present invention, the water softener housing includes an annular concave surface surrounding the first outlet on the first side of the middle frame facing away from the salt tank, thereby forming an open structure around the first outlet. This increases the salt pouring area, allowing salt particles that fall around the first outlet to be directed toward the first outlet, reducing the likelihood of salt particles falling outside the water softener and facilitating cleanliness of the water softener's salt inlet. Furthermore, salt particles are more easily distributed to the edge channels of the grille assembly, improving the uniformity of salt particle distribution.

[0011] According to one embodiment of the present invention, the annular concave surface transitions in an arc shape from an end thereof away from the first opening to an end thereof close to the first opening.

[0012] According to one embodiment of the present invention, the grille assembly is detachably connected to the middle frame.

[0013] According to one embodiment of the present invention, the outer frame is passed through the first passage, and the outer frame includes a limiting section extending along its axial direction, and the limiting section is gradually expanded in the direction toward the entrance of the channel. The middle frame is provided with a limiting structure, and the limiting structure cooperates with the limiting section to limit the movement of the limiting section relative to the middle frame toward the salt box.

[0014] According to one embodiment of the present invention, the limiting structure is an annular limiting plate connected to the first opening, one end of the annular limiting plate is connected to an end of the annular concave surface close to the first opening, and extends in a direction away from the annular concave surface;

[0015] The annular limiting plate has a first stopping section extending along its axial direction. The first stopping section is tapered in a direction toward the outlet of the channel. The inner side surface of the first stopping section is adapted to the outer side surface of the limiting section.

[0016] According to one embodiment of the present invention, the annular limiting plate has a second stop segment extending along its axial direction, the second stop segment connects the annular concave surface and the first stop segment, and the second stop segment is used to limit the axial offset of the limiting segment relative to the first passage.

[0017] According to one embodiment of the present invention, the grille assembly further comprises a plurality of annular baffles, which are spaced apart in sequence from the inside to the outside, and the outer frame is arranged around the outside of the plurality of annular baffles, and the channel is formed between each adjacent two annular baffles and between the outer frame and the outermost annular baffle.

[0018] According to one embodiment of the present invention, a plurality of spokes are provided in each of the channels, and each adjacent two annular partitions and the outer frame and the outermost annular partition are connected by a plurality of spokes. The plurality of spokes in each of the channels are evenly spaced around the circumference of the annular partition.

[0019] According to one embodiment of the present invention, the annular baffle has an outlet end corresponding to the outlet of the channel, and the outlet end is located outside the outer frame. The annular baffle includes a guide section arranged along its axial direction, and the outlet end is formed at one end of the guide section close to the outlet of the channel, and the guide section is gradually expanded in the direction toward the outlet end.

[0021] According to one embodiment of the present invention, the outer frame has a second end corresponding to the outlet of the channel, and the relative distance between the outlet end of the inner annular baffle and the second end of each adjacent two annular baffles is greater than the relative distance between the outlet end of the outer annular baffle and the second end.

[0022] According to one embodiment of the present invention, the annular partition has an inlet end corresponding to the inlet of the channel, the outer frame has a first end corresponding to the inlet of the channel and a second end corresponding to the outlet of the channel, and the inlet end is located between the first end and the second end.

[0023] A water softener according to an embodiment of the first aspect of the present invention includes the water softener housing described in any one of the above embodiments.

[0024] The above one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0025] The annular concave surface on the middle frame increases the salt pouring area, allowing some salt particles that fall around the first outlet to be diverted there, reducing the possibility of salt particles falling outside the water softener and helping to keep the salt inlet of the water softener clean. This allows salt particles to be more easily distributed throughout the various channels of the grille assembly, improving the uniformity of the grille assembly's salt distribution.

[0026] Furthermore, by cooperating with the first stop section of the annular limit plate and the limit section of the grille assembly, the connection strength between the middle frame and the grille assembly is improved, and the salt particles on the annular concave surface are facilitated to slide into the channel of the grille assembly through the annular concave surface and the first stop section in sequence.

[0060] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0061] In the description of the embodiments of the present invention, it should be noted that the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present invention and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on the specific circumstances.

[0063] In the embodiments of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," or "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," or "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0064] like Figure 1 As shown, the water softener includes a water softener housing, a salt well 200, and a resin tank 300. A first accommodating chamber 101 is provided within the water softener housing. The salt well 200 is disposed within the first accommodating chamber 101, and the resin tank 300 is connected to the first accommodating chamber 101. The first accommodating chamber 101 is used to store salt particles. Optionally, the resin tank 300 is disposed within the first accommodating chamber 101.

[0065] During operation, calcium and magnesium ions in the water flowing through the resin tank 300 are exchanged with the resin inside and then adsorbed, reducing the concentration of calcium and magnesium ions in the water and softening the water. When the resin in the resin tank 300 is fully adsorbed with calcium and magnesium ions, the salt water dissolved in the first accommodating chamber 101 is drawn into the resin tank 300 through the salt valve in the salt well 200, regenerating the resin in the resin tank 300 and enabling the repeated use of the resin in the resin tank 300.

[0066] The water softener housing is equipped with a salt inlet connected to the first accommodating chamber 101 within the water softener housing. Salt is added to the first accommodating chamber 101 through the salt inlet. During installation and user operation of the water softener, salt particles may accumulate in the first accommodating chamber 101 in a mountain-like shape, affecting the salt particle loading capacity in the first accommodating chamber 101 and the detection accuracy of the salt level detector, thereby affecting the salt dissolution effect.

[0067] In this regard, an embodiment of the present invention provides a grid assembly 4 for a water softener. Figures 8-14 The grille assembly 4 provided in this embodiment of the present invention includes an outer frame 41 and a plurality of annular baffles 42. The plurality of annular baffles 42 are sequentially spaced from the inside out, with the outer frame 41 disposed around the outer sides of the plurality of annular baffles 42. A channel 43 is formed between each adjacent pair of annular baffles 42, as well as between the outer frame 41 and the outermost annular baffle 42. The channels 43 allow salt particles to pass through.

[0068] Specifically, the grille assembly 4 includes multiple outer walls, which are connected to form an outer frame 41. A plurality of annular baffles 42 are sequentially arranged from the inside out. A channel 43 is formed within the innermost annular baffle 42, a channel 43 is formed between each adjacent pair of annular baffles 42, and a channel 43 is formed between the outermost annular baffle 42 and the outer frame 41. Thus, the grille assembly 4 is formed with multiple channels 43 distributed radially from the inside out.

[0069] The grille assembly 4 provided in this embodiment of the present invention comprises a plurality of annular baffles 42 disposed on the inner side of an outer frame 41. The baffles 42 are spaced apart from each other from the inside out, thereby forming a plurality of channels 43 radially distributed from the inside out. This grille assembly 4 can be installed at the salt inlet of a water softener housing and communicates with a first accommodating chamber 101 for storing salt particles. When salt is poured into the salt inlet, the grille assembly 4 breaks up a large number of salt particles and diverts them into the various channels 43, where they fall into the first accommodating chamber 101 in a relatively dispersed manner, ensuring a more even distribution of the salt particles.

[0070] Furthermore, the width and length of the channel 43 are both no less than twice the maximum size of the salt particles. This allows the salt particles to pass through the channel 43 more smoothly, and the salt particles passing through the channel 43 can effectively collide with the sidewalls of the channel 43, allowing the salt particles to fall into the first accommodating chamber 101 in a more dispersed manner.

[0071] The specific shape of the outer frame 41 can be adaptively set according to the specific shape of the salt addition port, and its cross-sectional shape can be rectangular, circular, triangular, elliptical, etc., which is not specifically limited in the present embodiment. The cross-sectional shape of the annular baffle 42 and the outer frame 41 can be the same or different. The cross-sectional shape of the annular baffle 42 can also be rectangular, circular, triangular, elliptical, etc., which is not specifically limited in the present embodiment. The cross-sectional shape here refers to the cross-sectional shape of the annular baffle 42 and the outer frame 41 perpendicular to the axial direction of the annular baffle 42.

[0072] For example, Figure 8 and Figure 10 As shown, the cross-sectional shapes of the outer frame 41 and the annular partition 42 are both rectangular. Figure 12 and Figure 14 As shown, the cross-sectional shape of the outer frame 41 is rectangular, and the cross-sectional shape of the annular partition 42 is circular.

[0073] like Figure 8 、 Figure 10 、 Figure 12 and Figure 14 As shown, the outer frame 41 is connected to the outermost annular baffles 42, and every two adjacent annular baffles 42 are connected to each other. Specifically, a plurality of spokes 44 are provided in each channel 43, connecting every two adjacent annular baffles 42, as well as the outer frame 41 and the outermost annular baffles 42, via the spokes 44. This increases the strength of the grille assembly 4 and reduces deformation of the outer frame 41 and annular baffles 42.

[0074] Furthermore, the multiple spokes 44 in each channel 43 are evenly spaced around the circumference of the annular partition 42, so that the multiple spokes 44 in each channel 43 are radially distributed toward the outer frame 41 with the axis of the annular partition 42 as the center, which can make the structure of the grille assembly more uniform and stable within its cross-sectional range.

[0075] It will be appreciated that the spokes 44 within each channel 43 are centrally symmetrically distributed about the axis of the annular baffle 42. For example, each salt pouring channel 43 may have four spokes 44 arranged in a cross pattern. The number of spokes 44 can be determined based on the size and structural strength requirements of the outer frame 41.

[0076] Optionally, the multiple spokes 44 in two adjacent channels 43 are arranged in a one-to-one correspondence, and the corresponding multiple spokes 44 are collinear in the length direction of the spokes 44, so that all the spokes 44 of the grille assembly 4 are radially distributed toward the outer frame 41 with the axis of the annular partition 42 as the center.

[0077] like Figure 11 and Figure 15As shown, the annular baffle 42 has an outlet end corresponding to the outlet of the channel 43. The outlet end of the annular baffle 42 is located outside the outer frame 41, and the annular baffle 42 includes a guide section 421 arranged along its axial direction. The end of the guide section 421 near the outlet of the channel 43 forms the outlet end of the annular baffle 42. The guide section 421 is gradually expanded in the direction toward the outlet end of the annular baffle 42, that is, the diameter of the guide section 421 gradually increases in the direction toward the outlet end of the annular baffle 42. Salt particles entering each channel 43 move along the channel 43 and collide back and forth between the side walls of the channel 43. Under the action of the guide section 421, some salt particles are able to diffuse toward the axial outside of the annular baffle 42, thereby allowing the salt particles passing through the grid assembly 4 to be spread over a larger area and more evenly within the first accommodating chamber 101.

[0078] Optionally, the sidewalls on either side of the guide section 421 may be parabolic in the longitudinal cross-section of the annular baffle 42. The longitudinal cross-section of the annular baffle 42 referred to herein is a cross-section parallel to the axis of the annular baffle 42. It will be appreciated that the guide section 421 as a whole forms a trumpet-like structure in the longitudinal cross-section of the annular baffle 42, thereby enabling salt particles to move a greater distance axially outward of the annular baffle 42 under the action of the guide section 421. Of course, the sidewalls on either side of the guide section 421 may also be linear in the longitudinal cross-section of the annular baffle 42, i.e., the guide section 421 as a whole forms a conical structure in the longitudinal cross-section of the annular baffle 42.

[0079] It should be noted that, when the diameter of the guide section 421 remains unchanged in the direction toward the outlet end of the annular partition 42, the outlet end of the annular partition 42 may be located inside the outer frame 41, see Figure 8 and Figure 9 , of course, it can also extend to the outside of the outer frame 41.

[0080] like Figure 11 As shown, the outer frame 41 has a second end 412 corresponding to the outlet of the channel 43. Of each pair of adjacent annular baffles 42, the relative distance between the outlet end of the inner annular baffle 42 and the second end 412 of the outer frame 41 is greater than the relative distance between the outlet end of the outer annular baffle 42 and the second end 412 of the outer frame 41. This reduces or prevents salt particles from hitting the outer annular baffle 42 at the outlet of the guide channel 43 and being bounced back, allowing the salt particles to move smoothly outward.

[0081] by Figure 11 The grille assembly 4 shown in the figure is a specific example, the number of annular baffles 42 is two, the relative distance between the outlet end of the inner annular baffle 42 and the second end 412 of the outer frame 41 is L1, and the relative distance between the outlet end of the outer annular baffle 42 and the second end 412 of the outer frame 41 is L2, L1>L2.

[0082] like Figure 9 、 Figure 11 、 Figure 13 and Figure 15 As shown, the annular baffle 42 has an inlet end corresponding to the inlet of the channel 43. The outer frame 41 has a first end 411 corresponding to the inlet of the channel 43 and a second end 412 corresponding to the outlet of the channel 43. The inlet end of the channel 43 is located between the first end 411 and the second end 412 of the outer frame 41. It will be understood that the inlet end of the annular baffle 42 is located inside the outer frame 41, and the relative distance between the inlet end of the annular baffle 42 and the second end 412 of the outer frame 41 is smaller than the relative distance between the first end 411 and the second end 412 of the outer frame 41.

[0083] It should be noted that when the grille assembly 4 is in use, the annular baffle 42 and the outer frame 41 are arranged in a vertical orientation. The inlet end of the annular baffle 42 is located between the first end 411 and the second end 412 of the outer frame 41, so that the highest point of the inlet end of the annular baffle 42 is lower than the lowest point of the first end 411 of the outer frame 41. This can reduce or prevent salt particles from rolling out of the outer frame 41 during the salt pouring process. It also prevents the annular baffle 42 from interfering with the inner surface of the flip cover assembly 2.

[0084] by Figure 9 The grille assembly shown in is a specific example, the relative distance between the highest position of the inlet end of any annular partition 42 and the second end 412 of the outer frame 41 is L3, and the relative distance between the lowest position of the first end 411 of the outer frame 41 and the second end 412 is L4, L3<L4.

[0085] The embodiment of the present invention does not specifically limit the height relationship between the multiple annular partitions 42. For example, Figures 8-15 As shown, the relative distance between the inlet end of the inner annular baffle 42 of each two adjacent annular baffles 42 and the first end 411 of the outer frame 41 is smaller than the distance between the inlet end of the outer annular baffle 42 and the first end 411 of the outer frame 41. This allows the grille assembly 4 to match the arched inner side surface of the flip cover assembly 2. Of course, the relative distance between the inlet end of the inner annular baffle 42 of each two adjacent annular baffles 42 and the first end 411 of the outer frame 41 may also be larger than the distance between the inlet end of the outer annular baffle 42 and the first end 411 of the outer frame 41.

[0086] like Figure 9 and Figure 11 As shown, the first end 411 of the outer frame 41 is inclined relative to the second end 412. The end surface of the inlet end of each annular baffle 42 corresponding to the inlet of the channel 43 is parallel to the end surface of the first end 411 of the outer frame 41, which can enhance the appearance consistency of the inlet end of the annular baffle 42 and the first end 411 of the outer frame 41.

[0087] Furthermore, the outer frame 41 includes a limiting section 413 extending axially thereof. The limiting section 413 gradually expands toward the entrance of the passage 43. Optionally, the end of the limiting section 413 near the entrance of the passage 43 forms the first end 411 of the outer frame 41. Of course, the limiting section 413 can also be a flange protruding from the outer side of the outer frame 41.

[0088] As will be appreciated, the outer frame 41 has an annular flange extending outwardly from one end of the outer frame 41 near the entrance of the passage 43. The retaining section 413 is configured to engage with the salt inlet on the water softener housing, allowing the grille assembly 4 to be hung on the middle frame 11 via the retaining section 413, eliminating the need for other connectors to connect the middle frame 11 and the grille assembly 4, thereby facilitating assembly and disassembly of the grille assembly 4.

[0089] Furthermore, the embodiment of the present invention also provides a water softener housing, such as Figure 1 and Figure 2 As shown, the water softener housing includes a salt tank 3, a middle frame assembly 1, and a grille assembly 4 for a water softener as described in any of the above embodiments. The salt tank 3 defines a first accommodating chamber. The middle frame assembly 1 is connected to the top of the salt tank 3 and has a salt inlet connected to the first accommodating chamber 101. The grille assembly 4 is positioned at the salt inlet, connecting the salt inlet, the passage 43, and the first accommodating chamber 101.

[0090] The middle frame assembly 1 includes a middle frame 11, and the middle frame 11 is provided with a first opening 111 (refer to Figure 7 ), the first port 111 can form the salt inlet of the water softener. The grille assembly 4 described in the above embodiment can also be considered as a component of the middle frame assembly 1.

[0091] When adding salt during the installation and use of the water softener, in order to make the salt particles as flat as possible in the first accommodating chamber 101, certain operations of the user during the salt pouring process may cause the salt particles to roll out of the water softener housing, causing additional cleaning work for the user and affecting the user experience.

[0092] In this regard, an embodiment of the present invention provides a water softener housing, such as Figure 1-Figure 3 As shown, the water softener housing includes a salt box 3, a middle frame 11 and a grid assembly 4. Figure 21 and Figure 23The middle frame 11 is provided with a first side 11a and a second side 11b opposite to each other, and a first passage 111 passing through the first side 11a and the second side 11b. The second side 11b of the middle frame 11 is connected to the top of the salt box 3. The first side 11a is the side of the middle frame 11 facing away from the salt box 3, and the second side 11b is the side of the middle frame 11 facing the salt box 3. The first side 11a of the middle frame 11 is provided with an annular concave surface 113 surrounding the first passage 111. The height of the first passage 111 relative to the salt box 3 is less than the height of the annular concave surface 113 relative to the salt box 3. The grille assembly 4 includes an outer frame 41. A plurality of channels 43 for salt particles to pass through are formed in the outer frame 41. The outer frame 41 is provided at the first passage 111 so that the channels 43 are connected to the interior of the salt box 3.

[0093] A first accommodating chamber 101 is formed between the middle frame 11 and the salt tank 3. A first port 111 communicates with the first accommodating chamber 101. The first port 111 can serve as a salt inlet for a water softener. Optionally, the inner edge of the annular concave surface 113 abuts the outer edge of the first port 111.

[0094] It is understood that the annular concave surface 113 forms an open structure around the first port 111. For example, the annular concave surface 113 transitions in an arc from its end away from the first port 111 to its end closer to the first port 111. For another example, the annular concave surface 113 transitions in a straight line from its end away from the first port 111 to its end closer to the first port 111, that is, the annular concave surface 113 is a conical surface. In this way, on the one hand, salt particles that fall onto the annular concave surface 113 can slide down it into the salt addition port, and on the other hand, it can cooperate with the inner side surface of the flip cover assembly 2 installed on the middle frame 11, effectively limiting the movement of the flip cover assembly 2 and improving the reliability of the flip cover assembly 2.

[0095] For another example, the annular concave surface 113 transitions in a straight line from an end thereof away from the first opening 111 to an end thereof close to the first opening 111. It can be understood that the annular concave surface 113 is constructed as an inverted conical structure.

[0096] The middle frame 11 and the grille assembly 4 can be integrally formed, fixedly connected, or detachably connected. A plurality of channels 43 are formed within the grille assembly 4. When salt is poured into the salt inlet, a large number of salt particles are broken up by the action of the grille assembly 4 and diverted into the salt tank 3 through the various channels 43. It should be noted that the grille assembly 4 can have a uniform grid structure, such as a honeycomb structure, or can be any of the grille assemblies 4 described in the aforementioned embodiments to achieve a better diversion effect.

[0097] The water softener provided in this embodiment of the present invention features an annular concave surface 113 surrounding the first opening 111 on the first side 11a of the middle frame 11, facing away from the salt tank 3. This creates an open structure around the first opening 111, thereby increasing the salt pouring area. Salt particles that fall around the first opening 111 are directed toward the first opening 111, reducing the likelihood of salt particles falling outside the water softener and facilitating cleanliness of the water softener's salt inlet. Furthermore, salt particles are more easily distributed to the edge channels 43 of the grille assembly 4, improving the uniformity of salt particle distribution.

[0098] like Figure 2 and Figure 26 As shown, the outer frame 41 is provided in the first opening 111, and the outer frame 41 includes a limiting section 413 extending along its axial direction, and the limiting section 413 is gradually expanded in the direction toward the entrance of the channel 43. The middle frame 11 is provided with a limiting structure (refer to Figure 21 The first stop section 1141 and the second stop section 1142 in the middle) cooperate with the limit structure 413 to limit the movement of the grid assembly 4 relative to the middle frame 11 toward the salt box 3.

[0099] During actual use of the water softener, with the first opening 111 facing upward, the grille assembly 4 can be lowered from the top of the middle frame 11 into the first opening 111. A retaining structure on the middle frame 11 prevents the grille assembly 4 from further moving relative to the middle frame 11 toward the brine tank 3, effectively allowing the grille assembly 4 to be hung on the middle frame 11. To remove the grille assembly 4, simply lift it upward. Alternatively, the retaining structure can be a bolt threaded into the middle frame 11, allowing the first section of the outer frame 41 to be removably connected to the middle frame 11.

[0100] Specifically, the limiting structure is an annular limiting plate 114 connected to the first passage 111. One end of the annular limiting plate 114 is connected to the end of the annular concave surface 113 close to the first passage 111, and extends in a direction away from the annular concave surface 113. The annular limiting plate 114 has a first stop section 1141 extending along its axial direction. The first stop section 1141 is tapered in the direction toward the outlet of the channel 43, and the inner side surface of the first stop section 1141 is adapted to the outer side surface of the limiting section 413. The annular limiting plate 114 is fixedly connected to the middle frame 11 or integrally formed. The first stop section 1141 is used to stop the limiting section 413 from moving relative to the middle frame 11 toward the salt box 3 to prevent the grille assembly 4 from falling into the salt box 3.

[0101] As will be appreciated, the inner side of the first stop segment 1141 is formed with an annular limiting surface. In use, the limiting segment 413 rests on this annular limiting surface. This embodiment allows the grille assembly 4 to be supported by the entire annular limiting surface of the first stop segment 1141, thereby enhancing the connection strength between the middle frame 11 and the grille assembly 4. This also facilitates salt particles on the annular concave surface to slide sequentially through the annular concave surface 113 and the first stop segment 1141 into the channel 43 of the grille assembly 4.

[0102] Furthermore, the annular stop plate 114 has a second stop section 1142 extending axially thereof. The second stop section connects the annular concave surface 113 and the first stop section 1141. The second stop section 1142 is used to limit the axial deviation of the stop section 413 relative to the first opening 111. It will be appreciated that the inner side surface of the second stop section 1142 also forms an annular stop surface, which surrounds the outer end of the stop section 413. The annular stop surface matches the shape of the end of the stop section 413, thereby limiting the left and right swing of the grille assembly 4 on the middle frame 11.

[0103] After the water softener is filled with water, water may accumulate on the shell surface of the water softener. The accumulated water can easily enter the control component 400 and other electrical components arranged in the salt box 3, affecting the performance of the electrical components and even causing a short circuit in the electrical components, affecting the safe use of the water softener.

[0104] In this regard, an embodiment of the present invention provides a water softener housing, see Figure 1 and Figure 25 The water softener includes a brine tank 3 and a middle frame 11. The brine tank 3 is provided with a first accommodating chamber 101 and a second accommodating chamber 102, which are isolated from each other. The middle frame 11 has a first side 11a and a second side 11b, which are opposite to each other. The second side 11b of the middle frame 11 is connected to the top of the brine tank 3. The first side 11a of the middle frame 11 faces away from the brine tank 3, while the second side 11b of the middle frame 11 faces one side of the brine tank 3.

[0105] The middle frame 11 is provided with a second opening 112, a cantilever slot 115, and a guide slot 116. The second opening 112 communicates with the second accommodating chamber 102. The cantilever slot 115 is isolated from the second accommodating chamber 102 and communicates with the first accommodating chamber 101. The guide slot 116 communicates with the cantilever slot 115. The guide slot 116 is provided on the first side 11a of the middle frame 11 and is located on at least one side of the second opening 112. The cantilever slot 115 is used to accommodate the cantilever 22 of the flip cover assembly 2, which is rotatably mounted on the middle frame 11.

[0106] The second opening 112 serves as a maintenance port for the water softener. The control assembly 400 is located within the second accommodating chamber 102, and maintenance operations on the control assembly 400 can be performed through the second opening 112. The second side 11b of the middle frame 11 faces the brine tank 3. Both the second opening 112 and the cantilever slot 115 extend through the first side 11a and the second side.

[0107] In an embodiment of the present invention, a guide groove 116 connected to the cantilever groove 115 is provided on the first side 11a of the middle frame 11. The guide groove 116 can converge water droplets splashed onto the first side 11a of the middle frame 11 and guide the converged water to flow into the first accommodating chamber 101, thereby effectively preventing accumulated water from entering the second accommodating chamber 102 through the second passage 112, thereby avoiding the risk of electric shock caused by electrical components encountering water.

[0108] Specifically, the water softener provided in this embodiment of the present invention also includes an inner frame 13, which is disposed between the middle frame 11 and the salt tank 3 and is located on the second side 11b of the middle frame 11. The inner frame 13 defines a second accommodating chamber 102 for accommodating the control assembly 400. A first accommodating chamber 101 is formed between the inner frame 13 and the salt tank 3. The inner frame 13 is provided with a third port corresponding to the first port 111. The first port 111 and the third port communicate with each other to form a salt addition port.

[0109] Furthermore, a resin tank 300 is provided in the salt box 3. Part of the resin tank 300 is located in the first accommodating chamber 101, and the other part is located in the second accommodating chamber 102 and is connected to the control component 400. The control component 400 is connected to the resin tank 300 and the salt valve in the salt well 200 respectively.

[0110] There are two cantilever grooves 115, and the guide groove 116 is arranged around the side of the second passage 112. One end of the guide groove 116 is connected to one of the cantilever grooves 115, and the other end of the guide groove 116 is connected to the other cantilever groove 115. It can be understood that the guide groove 116 is a U-shaped groove structure with two ends connected to the two cantilever grooves 115 respectively. For example, if the second passage 112 is rectangular, the two cantilever grooves 115 are arranged on one side of the second passage 112, and the guide grooves 116 are arranged on the other three sides of the second passage 112. This can effectively prevent accumulated water around the second passage 112 from flowing into the second accommodating chamber 102.

[0111] Optionally, the depth of the portion of the guide groove 116 close to the cantilever groove 115 is greater than the depth of the portion of the guide groove 116 away from the cantilever groove 115. When the first side 11a of the middle frame 11 is substantially horizontal, such a configuration can make the bottom of the guide groove 116 present a certain slope or gradient, thereby accelerating the drainage speed of the guide groove 116.

[0112] Optionally, the middle frame 11 is tilted in a first direction relative to the bottom surface of the salt box 3 so that the water in the guide groove 116 flows into the cantilever groove 115. Figure 1 The direction indicated by the arrow is the first direction. Due to the tilted arrangement of the middle frame 11, the water flowing into the guide groove 116 can automatically flow along the guide groove 116 toward the cantilever groove 115 under the action of its own weight, thereby preventing water flow or droplets from entering the second port 112 as much as possible, ensuring the normal operation of the water softener and power supply safety.

[0113] like Figure 1 As shown, the angle α between the first direction shown in this embodiment and the bottom surface of the salt box 3 is 5° to 30°. For example, the angle α can be 5°, 10°, 20° and 30°, which is not specifically limited here.

[0114] Combine Figure 1 and Figure 25 The water softener housing is equipped with a rotatable flip cover assembly 2 and a cantilever slot 115. The cantilever 22 of the flip cover assembly 2 is rotatably mounted on the housing. The cantilever slot 115 accommodates the cantilever 22 and provides clearance for its rotation. During product installation and user use, when adding salt, salt particles can easily fall into the cantilever slot 115 and become difficult to remove, potentially causing the flip cover assembly 2 to become stuck or corroding other components.

[0115] In this regard, an embodiment of the present invention provides a water softener housing, see Figure 6 、 Figure 7 、 Figure 21-24 、 Figure 27 The water softener housing includes: a salt box 3, a middle frame 11 and a flow guide 12. A first accommodating chamber 101 for accommodating salt particles is provided in the salt box 3. The middle frame 11 is connected to the top of the salt box 3. A first passage 111 and a cantilever groove 115 are provided on the middle frame 11. The first passage 111 is connected to the first accommodating chamber 101. The flow guide 12 is provided on the side of the middle frame 11 facing the salt box 3 and forms a guide groove 117 for salt particles to pass through between the middle frame 11. The guide groove 117 connects the cantilever groove 115 and the first accommodating chamber 101. The cantilever groove 115 is used to accommodate the cantilever 22 of the flip cover assembly 2. The cantilever 22 can be rotatably mounted on the middle frame 11. The first passage 111 serves as a salt adding port.

[0116] The water softener housing provided in this embodiment has a guide member 12 disposed on the middle frame 11 to form a guide groove 117. The guide groove 117 connects the cantilever groove 115 and the first accommodating chamber 101. This allows salt particles that fall into the cantilever groove 115 during the salt addition operation to slide along the guide groove 117 into the first accommodating chamber 101. This prevents salt particles from accumulating in the cantilever groove 115 and causing the cantilever 22 to become stuck, and prevents salt particles from corroding components disposed in the cantilever groove 115.

[0117] Optionally, the guide groove 117 is away from the notch of the cantilever groove 115 and faces the side where the first passage 111 is located, so that the salt particles can slide along the guide groove 117 into the salt pile below the first passage 111.

[0118] like Figure 22-24 As shown, the flow guide 12 includes a guide plate 121 and two side plates 122. The two side plates 122 are respectively connected to the guide plate 121 on both sides of the flow diversion direction. The two side plates 122 are connected to the second side 11b of the middle frame 11 to form a guide groove 117. The flow diversion surface of the guide plate 121 faces the cantilever groove 115. Optionally, the side plates 122 can be welded to the middle frame 11 or connected to the middle frame 11 by bolts. This embodiment simplifies the manufacturing process of the middle frame assembly 1 by providing a separate middle frame 11 and flow guide 12 to form the guide groove 117.

[0119] Furthermore, the ends of the two side panels 122 facing away from the guide plate 121 align with the second side 11b of the middle frame 11, allowing for a seamless connection between the two side panels 122 and the middle frame 11. The ends of the guide panels 121 facing the cantilever groove 115 align with the second side 11b of the middle frame 11, allowing for a seamless connection between the guide panels 121 and the middle frame 11. This improves the sealing between the guide groove 117 and the cantilever groove 115 and the second accommodating chamber 102. When the side panels 122 are welded to the middle frame 11, the welding performance between the two sides is also improved.

[0120] See also Figure 27 The cantilever trough 115 is provided with a first trough wall 1151 away from the first passage 111. The end of the first trough wall 1151 facing the inside of the salt tank 3 extends obliquely toward the first passage 111. The end of the guide plate 121 near the cantilever trough 115 is butted against the end of the first trough wall 1151 facing the inside of the salt tank 3, so that the first trough wall 1151 and the guide plate 121 are connected to form a relatively smooth guide wall, so that salt particles can be smoothly discharged.

[0121] Furthermore, an arcuate section 1211 is provided at one end of the guide plate 121, proximal to the cantilevered trough 115. The arcuate section 1211 curves toward the guide surface of the guide plate 121. The end of the arcuate section 1211 abuts against the end of the first trough wall 1151 facing inward from the salt tank 3. This creates an arcuate chamfer at the junction of the first trough wall 1151 and the guide plate 121. This improves the smoothness of the transition between the first trough wall 1151 and the guide plate 121, further facilitating the smooth discharge of salt particles.

[0122] See also Figure 27The cantilevered groove 115 is provided with a second groove wall 1152 proximate to the first passage 111. The second groove wall 1152 extends obliquely from one end facing the inside of the salt box 3, away from the first passage 111. Thus, the second groove wall 1152 is arranged at an angle to the first side 11a of the middle frame 11, thereby forming a reinforcement structure for the middle frame 11 at the opening of the cantilevered groove 115 and improving the structural strength of the middle frame 11 at the cantilevered groove 115. For example, the second groove wall 1152 is connected to the annular concave surface 113 in the above-described embodiment and is also connected to the annular concave surface 113 on the first side 11a, with the angle β between the second groove wall 115 and the first side 11a being between 90° and 130°.

[0123] A gap exists between the second groove wall 1152 and the cantilever 22 of the flip cover assembly 2, allowing salt particles to pass through. The second groove wall 1152 serves as a guide, directing salt particles that fall into the gap into the cantilever groove 115 and then out through the guide groove 117. Optionally, the end of the second groove wall 1152 facing the inside of the salt tank 3 faces the guide plate 121.

[0124] In this embodiment of the present invention, there are multiple cantilever slots 115, and the number of flow guides 12 can be one or more. When there is only one flow guide 12, the width of the guide plate 121 spans across multiple cantilever slots 115, forming a guide slot 117 that is connected to multiple cantilever slots 115. When there are multiple flow guides 12, the multiple cantilever slots 115 and the multiple flow guides 12 are arranged in a one-to-one correspondence, thereby forming a guide slot 117 that is connected to each of the multiple cantilever slots 115. This ensures that the middle frame 11 has a certain structural strength.

[0125] When the first side 11a of the middle frame 11 is provided with the guide groove 116 described in the above embodiment, the guide groove 116 is connected to the cantilever groove 115. Water flowing from the guide groove 116 into the cantilever groove 115 can be discharged through the guide groove 117, thereby preventing water from accumulating in the cantilever groove 115. Furthermore, the middle frame 11 is provided with a second port 112 that is connected to the second accommodating chamber 102. The positional relationship between the guide groove 116 and the second port 112 can be seen in the above-mentioned related embodiments and will not be repeated here.

[0126] Furthermore, the water softener housing provided in the embodiment of the present invention also includes an inner frame 13, which is arranged between the salt box 3 and the middle frame 11. A first accommodating chamber 101 is formed between the inner frame 13 and the salt box 3, and a second accommodating chamber 102 is formed between the inner frame 13 and the middle frame 11. The guide groove 117 is isolated from the second accommodating chamber 102.

[0127] The second accommodating chamber 102 is used to accommodate the water softener control assembly 400. This embodiment allows water and salt particles entering the cantilever groove 115 to be directed into the first accommodating chamber 101 and prevented from entering the second accommodating chamber 102, thereby preventing the salt particles from corroding the control assembly 400 in the second accommodating chamber 102.

[0128] Furthermore, the flow guide 12 is disposed within the second accommodating chamber 102. The inner frame 13 has an outer side surface 132 corresponding to the second accommodating chamber 102. The outer side surface 132 faces the first port 111. The notch of the guide groove 117, which is away from the cantilever groove 115, is flush with the outer side surface 132. It will be appreciated that the flow guide 12 is disposed between the inner frame 13 and the middle frame 11 and is embedded on the side of the inner frame 13 near the middle frame 11. This allows for a compact structure after the inner frame 13, middle frame 11, and flow guide 12 are installed. The notch of the guide groove 117, which is away from the cantilever groove 115, is flush with the outer side surface 132, which improves the appearance. Of course, the notch can also protrude beyond the outer side surface 132.

[0129] The water softener provided in this embodiment of the present invention also includes a flip cover assembly 2. A first opening 111 serves as the water softener's salt inlet, and the flip cover assembly 2 is used to close or open the first opening 111. Specifically, the flip cover assembly 2 includes a first cover 21 and a cantilever 22. The first end of the cantilever 22 is connected to one end of the first cover 21, and the second end of the cantilever 22 is rotatably connected to the middle frame 11, allowing the first cover 21 to flip between a first position closing the first opening 111 and a second position opening the first opening 111. When the first cover 21 is in the first position, the cantilever 22 is retracted into the cantilever slot 115.

[0130] The inner surface of the first cover 21 is provided with an arcuate surface on its circumference, which matches the annular concave surface 113 on the middle frame 11 to limit the position of the first cover 21 and prevent the first cover 21 from shaking.

[0131] Furthermore, the water softener further comprises a second cover 6, which is detachably connected to the middle frame 11 for closing or opening the second opening 112. For example, the second cover 6 is connected to the middle frame 11 by bolts or by snap fasteners.

[0132] like Figure 1 and Figure 28As shown, the cantilever 22 includes a long arm section 221 and a short arm section 222. The long arm section 221 is in an arc shape, and the short arm section 222 is in a straight line shape. The first end of the long arm section 221 is connected to one end of the first cover body 21, the second end of the long arm section 221 is connected to the first end of the short arm section 222, and the second end of the short arm section 222 is rotatably connected to the middle frame 11. Among them, the distance between the second end of the short arm section 222 and the first end of the long arm section 221 is smaller than the distance between the first end of the short arm section 222 and the first end of the long arm section 221, so that the cantilever 22 is similar to a fishhook. The cantilever 22 of this structure can make the first cover body 21 flip angle relative to the middle frame 11 greater than 90°.

[0133] This embodiment is based on the optimized design of the cantilever 22, which not only enables the first cover body 21 to achieve a relatively large flip angle relative to the middle frame 11, but also allows the first cover body 21 to be as far away from the first port 111 as possible when reaching the maximum flip angle, thereby improving the convenience of the salt adding operation.

[0134] See also Figure 28 The middle frame 11 is provided with an abutment portion 118, and the cantilever 22 is provided with a stop portion 223. When the first cover 21 is in the first position, the stop portion 223 is separated from the abutment portion 118; when the first cover 21 is in the second position, the stop portion 223 abuts against the abutment portion 118. The second position of the first cover 21 shown in this embodiment corresponds to the position at which the first cover 21 reaches the maximum tilt angle relative to the middle frame 11. For example, the maximum tilt angle of the first cover 21 relative to the middle frame 11 can reach 100° to 150°.

[0135] Since the first cover body 21 is in an inclined state relative to the vertical plane when the first cover body 21 is in the second position, the mutual abutment between the stop portion 223 and the abutment portion 118 can enable the first cover body 21 to reach a force balance state. Without the need for manual support by the operator, the first cover body 21 can also be stably maintained in the second position, and its state will not change. Only when the first opening 111 needs to be closed, the first cover body 21 is flipped from the second position to the first position under the drive of the operator.

[0136] To facilitate controlling the tilting angle of the first cover 21 relative to the middle frame 11, the stopper 223 shown in this embodiment is disposed on the outer side of the cantilever 22, and the abutment 118 is disposed on the wall of the cantilever slot 115, facing the outer side of the cantilever 22. Thus, when the first cover 21 is in the first position, the cantilever 22 is retracted within the cantilever slot 115, and the stopper 223 is spaced apart from the abutment 118. As the first cover 21 rotates relative to the middle frame 11 in the first rotational direction, from the first position to the second position, the stopper 223 gradually approaches the abutment 118 as the cantilever 22 rotates. When the stopper 223 abuts the abutment 118, the first cover 21 reaches the second position and cannot continue to rotate in the first rotational direction.

[0137] In practical applications, the maximum tilt angle of the first cover 21 can be selectively controlled as needed. In this embodiment, the cantilever 22 is provided with multiple mounting positions, which are arranged in sequence along the extension direction of the cantilever 22. The stopper 223 can be selectively and detachably connected to any of the multiple mounting positions.

[0138] In this embodiment, multiple mounting locations can be provided on the outer side of the cantilever 22. Each mounting location can be a snap-fitting groove provided on the outer side of the cantilever 22, and a snap-fitting head is formed on the stopper 223. After determining the maximum tilting angle of the first cover 21, the operator can determine the snap-fitting groove corresponding to the maximum tilting angle and then directly snap the snap-fitting head on the stopper 223 into the snap-fitting groove corresponding to the maximum tilting angle, thereby controlling the first cover 21 to achieve the desired maximum tilting angle.

[0139] Optionally, the width of the abutment portion 118 is greater than or equal to the width of the cantilever groove 115, so that when the first cover body 21 is in the second position, the abutment portion 118 can close the gap between the cantilever 22 and the cantilever groove 115 to prevent salt particles from entering the cantilever groove 115.

[0140] An embodiment of the present invention further provides a water softener, which includes the water softener housing described in any of the above embodiments.

[0141] The water softener's salt tank 3 is equipped with a salt well 200, which contains a salt valve. This valve is used to draw brine from the salt tank into the resin tank 300. In existing water softeners, the salt well 200 is typically fixed to the side wall of the salt tank 3 using expansion screws. These expansion screws are difficult to install and remove, and their heads are exposed on the exterior of the water softener, affecting its aesthetics. Deformation of the salt tank 3 can cause the salt well 200 to tilt, affecting the sealing performance of the salt valve and causing it to fail. The blow-molded salt tank 3 also has an uneven thickness, which can easily cause the expansion screw holes on the salt tank 3 and the salt well 200 to misalign, making installation difficult.

[0142] In this regard, an embodiment of the present invention further provides a salt well installation device 500. Figures 16-20 As shown, the salt well installation device includes a clamp 51 and a connecting arm 52. The connecting arm 52 is connected to one side of the clamp 51, with the axial direction of the clamp 51 parallel to the length of the connecting arm 52. The connecting arm 52 is used to connect to the middle frame assembly 1 of the water softener. The clamp 51 is designed to be mounted on the outside of the salt well 200. The salt well installation device 500 is used to fix the salt well 200 in a vertical position.

[0143] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, during use, the end of the connecting arm 52 away from the clamp 51 is connected to the middle frame assembly 1, and the connecting arm 52 is arranged vertically to maintain the salt well 200 in a vertical position. Deformation of the salt tank 3 will not affect the middle frame assembly 1. Even if the salt tank 3 deforms, the salt well 200 can remain in a vertical position, thereby ensuring the sealing performance of the salt valve in the salt well 200 and preventing salt valve failure due to deformation of the salt tank 3.

[0144] In one embodiment, a clamp 51 can be used to securely hold the salt well 200, thereby achieving a fixed connection between the salt well 200 and the middle frame assembly 1. For example, the clamp 51 comprises a first and a second interconnected steel band, which are connected by a buckle to securely hold the salt well 200. The buckle is equipped with an adjustment mechanism for tightening the first and second steel bands to accommodate salt wells 200 of varying sizes. This prevents the salt well 200 from moving upward due to the buoyancy of water in the first accommodating chamber 101.

[0145] In another embodiment, the salt well installation device 500 further includes a stopper 53 disposed on the connecting arm 52. The clamp 51 is configured to be mounted on the outside of the salt well 200, and the stopper 53 is configured to restrict movement of the salt well 200 toward one end of the connecting arm 52. It is understood that the stopper 53 protrudes from the side of the connecting arm 52, and at least a portion of the projection of the stopper 53 onto the clamp 51 along the length of the connecting arm 52 is located inside the clamp 51.

[0146] When in use, the stopper 53 is positioned above the salt well 200 and contacts its upper end, thereby preventing the salt well 200 from moving upward. The salt well installation device 500 provided in this embodiment of the present invention utilizes the stopper 53 provided on the connecting arm 52 to restrict upward movement of the salt well 200, thereby ensuring the sealing of the salt valve. By providing the stopper 53 in this embodiment, the clamp 51 does not need to be tightly gripped against the salt well 200, and can even provide a loose fit between the clamp 51 and the salt well 200.

[0147] The stopper 53 can be integrally formed with the connecting arm 52, or can be fixedly or detachably connected to the connecting arm 52. The clamp 51, connecting arm 52, and stopper 53 can be integrally formed. In some embodiments of the present invention, the position of the stopper 53 along the length of the connecting arm 52 is adjustable, allowing the salt well installation device 500 to be adapted for salt wells 200 of varying heights.

[0148] For example, Figure 18 and Figure 19 As shown, the limiting member 53 includes a limiting block 531 and a bolt 532. The limiting block 531 is movable along the length of the connecting arm 52. The bolt 532 is screwed to the limiting block 531 and abuts against the connecting arm 52. The limiting block 531 is used to abut against the salt well 200. The limiting block 531 is fastened to the connecting arm 52 by the bolt 532. When the position of the limiting member 53 needs to be adjusted, the bolt 532 is first removed, and then the limiting block 531 is moved to the desired position along the length of the connecting arm 52, and then the bolt 532 is tightened to secure it.

[0149] For another example, the limiting member 53 includes a limiting block 531, the limiting block 531 is provided with a limiting tooth 5311, the connecting arm 52 is provided with an inverted rack 521, the limiting tooth 5311 is cooperatively connected with the inverted rack 521, and the inverted rack 521 is used to limit the limiting tooth 5311 from moving in a direction away from or close to the clamp 51.

[0150] Specifically, the inverted rack 521 includes multiple beveled teeth tilted toward the clamp 51, with the stopper tooth 5311 located between two adjacent beveled teeth. The stopper tooth 5311 exhibits a certain degree of elastic deformation, allowing it to move toward the clamp 51 under a certain external force, but not away from it. This allows the position of the stopper 531 to be adjusted in one direction.

[0151] Optionally, a paddle 5312 is fixedly connected to the limiting tooth 5311. When adjusting the limiting block 531, the paddle 5312 can be moved to separate the limiting tooth 5311 from the inverted rack 521, thereby releasing the restraint imposed by the inverted rack 521 on the limiting tooth 5311. This reduces the force required to move the limiting block 531. After adjusting the limiting block 531 to the desired position, the paddle 5312 is released, allowing the limiting tooth 5311 to return to the position between the two inverted racks 521, completing the positioning.

[0152] Similarly, when the multiple oblique teeth are inclined in the direction away from the clamp 51, the limiting tooth 5311 can move in the direction away from the clamp 51 under a certain external force, but cannot move in the direction close to the clamp 51. The adjustment of the distance will not be repeated here.

[0153] Based on the above embodiment, two opposing clamping jaws 533 are provided on one side of the limit block 531, and the connecting arm 52 is clamped between the two clamping jaws 533. A limiting claw 5331 is provided on the end of the clamping jaw 533 away from the limit block 531, and the connecting arm 52 is restrained between the limiting claw 5331 and the limit block 531. The limit block 531 can be integrally formed with the clamping jaw 533. When installing the limit member 53, the connecting arm 52 can be simply inserted between the two clamping jaws 533 and then secured with the bolts 532, making installation convenient.

[0154] In the embodiment where the limit block 531 is fastened to the connecting arm 52 by a bolt 532, the bolt 532 is screwed to the side of the limit block 531 facing away from the clamping jaw 533 and abuts against the connecting arm 52. Of course, the limit block 531 can also be movably mounted on the connecting arm 52, so that the clamping jaw 533 is not required.

[0155] like Figure 19 and Figure 20 As shown, a mounting structure 54 is provided on at least one side of the connecting arm 52 away from the end of the clamp 51. The mounting structure 54 includes a mounting portion 541 and a limiting portion 542 protruding from the connecting arm 52. The mounting portion 541 and the limiting portion 542 are spaced apart along the length of the connecting arm 52. The mounting portion 541 and the limiting portion 542 are used to limit the vertical position of the connecting arm 52 relative to the middle frame assembly 1. For details, please refer to the following embodiment. The mounting structure 54 can be integrally formed with the connecting arm 52.

[0156] Furthermore, the mounting portion 541 is provided with a first mounting hole 5411 , and the first mounting hole 5411 is used for connecting the connecting arm 52 to the middle frame assembly 1 via a fastener passing through the first mounting hole 5411 .

[0157] To facilitate the connection and installation of the salt well 200 and the clamp 51, in some embodiments of the present invention, an opening 511 is provided on one side of the clamp 51. The opening 511 is used to allow the salt well 200 to pass through, so that the clamp 51 is positioned outside the salt well 200. It will be understood that the opening 511 forms a snap-in notch of the clamp 51. When the salt well 200 is installed, the clamp 51 can be clamped into the inside of the clamp 51 by deforming it to a certain extent.

[0158] The size of opening 511 is determined by the deformation of clamp 51 and the diameter of salt well 200, as long as the salt well 200 can fit within clamp 51. For example, the width of opening 511 is no less than half the diameter of salt well 200. Optionally, clamp 51 is made of plastic to ensure a certain degree of elasticity and toughness. Clamp 51 and connecting arm 52 are integrally formed.

[0159] Furthermore, a reinforcing rib 512 is provided on the side of the clamp 51 facing away from the opening 511. The reinforcing rib 512 can improve the toughness of the clamp 51, reduce the possibility of irreversible deformation of the clamp 51 caused by multiple disassembly and assembly with the salt well 200 times, maintain the external structure of the clamp 51, and extend the service life of the clamp 51.

[0160] Optionally, the side of the reinforcing rib 512 facing away from the opening 511 is configured as a straight edge. In use, this straight edge is spaced from the inner wall of the salt tank 3. The straight edge of the reinforcing rib 512 allows the clamp 51 to be positioned as close to the inner wall of the salt tank 3 as possible, reducing the installation space occupied by the salt well installation device 500. The connecting arm 52 is connected to either side of the clamp 51 between the reinforcing rib 512 and the opening 511.

[0161] Furthermore, an embodiment of the present invention provides a water softener, comprising a salt tank 3, a middle frame assembly 1, a salt well 200, and a salt well installation device 500 as described in any of the above embodiments. The salt well 200 is vertically disposed within the salt tank 3. The middle frame assembly 1 is connected to the top of the salt tank 3. A connecting arm 52 is assembled and connected to the middle frame assembly 1. A clamp 51 is disposed around the outside of the salt well 200. In embodiments with a stopper 53, the upper end of the salt well 200 abuts against the stopper 53.

[0162] The middle frame assembly 1 includes a middle frame 11, and the connecting arm 52 can be assembled and connected to the middle frame 11; alternatively, the middle frame assembly 1 further includes an inner frame 13, which is arranged between the middle frame 11 and the top of the salt box 3, and the connecting arm 52 is assembled and connected to the inner frame 13.

[0163] In this embodiment of the present invention, a mounting plate 133 is protruding from the sidewall of the middle frame assembly 1 and extending inwardly therefrom. A mounting structure 54 is provided on at least one side of the connecting arm 52, distal from the clamp 51. The middle frame assembly 1 is provided with a salt inlet connected to the salt tank 3. For example, the mounting plate 133 is a plate-like structure extending from one sidewall of the middle frame assembly 1 toward the salt inlet. The connecting arm 52 is mounted to the mounting plate 133 via the mounting structure 54.

[0164] Specifically, if Figure 20 As shown, the mounting structure 54 includes a mounting portion 541 and a limiting portion 542 protruding from the connecting arm 52. The mounting portion 541 and the limiting portion 542 are spaced apart in the length direction of the connecting arm 52, and the mounting plate 133 is limited between the mounting portion 541 and the limiting portion 542.

[0165] The mounting structure 54 and the connecting arm 52 form a U-shaped structure with an opening toward one side of the connecting arm 52. The mounting plate 133 is positioned within the opening of the U-shaped structure, allowing the connecting arm 52 to be suspended from the mounting plate 133. This embodiment facilitates the vertical installation and positioning of the salt well installation device 500 by sandwiching the mounting plate 133 between the mounting portion 541 and the limiting portion 542. Furthermore, the upper and lower limiting mechanisms can limit the lateral movement of the connecting arm 52 to a certain extent.

[0166] In addition to vertically limiting the connecting arm 52 via the mounting structure 54, the connecting arm 52 also needs to be horizontally limited. In some embodiments of the present invention, the mounting portion 541 is provided with a first mounting hole 5411, and the mounting plate 133 is provided with a second mounting hole 1331. The second mounting hole 1331 is provided corresponding to the first mounting hole 5411. The connecting arm 52 is connected to the mounting plate 133 via a fastener 55 that passes through the first mounting hole 5411 and the second mounting hole 1331.

[0167] During installation, the mounting plate 133 is first inserted into the U-shaped opening of the mounting structure 54, and the first mounting hole 5411 is aligned with the second mounting hole 1331, and then the two are fastened together by the fastener 55. The fastener 55 can be a bolt.

[0168] Optionally, the mounting portion 541 is located on a side of the limiting portion 542 away from the clamp 51. That is, the mounting portion 541 is located above the mounting plate 133, and the limiting portion 542 is located below the mounting plate 133. In this way, manual tightening operation of the fastener 55 can be facilitated.

[0169] On the basis of limiting the vertical direction of the connecting arm 52 by the mounting structure 54, the connecting arm 52 can also be limited in the horizontal direction by a clamping method. For example, the mounting plate 133 is provided with a clamping structure, and the connecting arm 52 is clamped to the mounting plate 133 by the clamping structure.

[0170] Specifically, the mounting plate 133 has a notch 1333, and the engaging structure includes two claws 1332 on either side of the notch 1333. The connecting arm 52 is disposed within the notch 1333 and is engaged between the two claws 1332. During installation, the connecting arm 52 can be pressed into the notch 1333, and the two claws 1332 will retain the connecting arm 52 within the notch 1333.

[0171] In some embodiments of the present invention, a snap-fit ​​structure is provided on the mounting plate 133, and the mounting portion 541 is fastened to the mounting plate 133 via fasteners 55. The snap-fit ​​structure can be used for initial positioning during installation, and then fastened via fasteners 55 to prevent loosening of the claws 1332 and shaking of the connecting arm 52.

[0172] When the mounting plate 133 is provided with a notch 1333 , mounting structures 54 are respectively provided on two opposite sides of the connecting arm 52 . The two mounting structures 54 are respectively connected to portions of the mounting plate 133 located on both sides of the notch 1333 .

[0173] like Figure 17 、 Figure 18 and Figure 20 As shown, the two mounting structures 54 and the connecting arm 52 form an I-shaped structure. The mounting plates 133 on either side of the notch 1333 are respectively positioned between the mounting portions 541 and the limiting portions 542 of the two mounting structures 54. This increases the connection strength between the connecting arm 52 and the mounting plates 133, more effectively preventing the connecting arm 52 from shaking left or right.

[0174] Optionally, first positioning blocks 1334 are provided on either side of the notch 1333 of the mounting plate 133, and the mounting portion 541 is positioned between the two first positioning blocks 1334. Alternatively, second positioning blocks 1335 are provided on either side of the notch 1333 of the mounting plate 133, and the limiting portion 542 is positioned between the two second positioning blocks 1335.

[0175] The distance between the two first positioning blocks 1334 is equal to the width of the mounting portion 541. The distance between the two second positioning blocks 1335 is equal to the width of the limiting portion 542. The two first positioning blocks 1334 and / or the two second positioning blocks 1335 facilitate rapid alignment of the first mounting hole 5411 and the second mounting hole 1331, thereby improving assembly efficiency.

[0176] In this embodiment, the mounting portion 541 can be further positioned in the second direction by means of the claw 1332 and / or the fastener 55. The first and second directions are perpendicular to each other. Without the fastener 55, the two first positioning blocks 1334 and / or the two second positioning blocks 1335 can prevent the connecting arm 52 from shaking in the first direction due to loosening of the claw 1332.

[0177] like Figure 16 As shown, in this embodiment of the present invention, the middle frame assembly 1 includes a first side wall 134, a second side wall 135, and a third side wall 136. The first side wall 134 and the second side wall 135 are arranged opposite each other, and the third side wall 136 connects the first side wall 134 and the second side wall 135. The mounting plate 133 is protruded from the third side wall 136 and connected to the first side wall 134 and the second side wall 135.

[0178] By connecting mounting plate 133 between three adjacent side walls, a mutually supporting structure is formed between mounting plate 133 and the three side walls. Mounting plate 133 not only serves to mount connecting arm 52, but also strengthens the structural strength of middle frame assembly 1. Furthermore, supported by first side wall 134, second side wall 135, and third side wall 136, mounting plate 133 achieves enhanced structural stability and is less susceptible to deformation under the influence of gravity within salt well installation device 500.

[0179] When the connecting arm 52 is assembled and connected to the middle frame 11, the mounting plate 133 and the first, second, and third side walls 134, 135, and 136 described in the above embodiment are disposed on the middle frame. When the connecting arm 52 is assembled and connected to the inner frame 13, the mounting plate 133 and the first, second, and third side walls 134, 135, and 136 described in the above embodiment are disposed on the inner frame 13. The middle frame 11 serves to provide a decorative shield for the mounting structure of the connecting arm 52 and the mounting plate 133.

[0180] Finally, it should be noted that the above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
