Solid salt dissolving aids for salt boxes, salt boxes and water softeners

Abstract

The present invention relates to a solid salt dissolution-promoting component for a salt box, a salt box and a water softener. The solid salt dissolution-promoting component includes a salt storage part, a limiting part and a supporting part for supporting the salt storage part; the wall in the salt storage part for contacting the solid salt is concave-convex and has a plurality of liquid holes. As described above, the supporting part of the solid salt dissolution-promoting component supports the salt storage part in the salt box. Due to the density difference between salt and water, the salt dissolved in the upper part of the salt box moves downward all the time, which will increase the concentration difference between the upper and lower parts of the salt box and thus accelerate the salt dissolution rate, and will also keep the dissolved salt in a state of motion and diffusion until the salt concentration is saturated, which can avoid the problem of freezing in areas with low temperatures, and can also avoid the stratification of salt water due to density difference, thereby improving the regeneration efficiency of the resin. In addition, the wall in the salt storage part for contacting the solid salt is concave-convex, which can increase the contact surface area between the solid salt and the water in the salt box, and can accelerate the dissolution of the solid salt.

Description

Technical Field

[0001] The invention relates to the technical field of electrical appliances, in particular to a solid salt dissolution-aiding component for a salt box, a salt box and a water softener. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the water quality they use. For example, the hardness of water used for washing should not be too high. Accordingly, water softeners that can use resin to soften water and remove scaling components (mainly calcium and magnesium ions) are becoming more and more popular. Among them, during the use of water softeners, it is necessary to regenerate the failed resin by adding concentrated salt water.

[0003] For existing water softeners, solid salt is generally placed directly at the bottom of the water softener salt tank for accumulation, and before regeneration, water is added to dissolve the solid salt to prepare concentrated brine required for regeneration.

[0004] However, the above-mentioned salt dissolving method has the following problems: 1) The density of salt is greater than that of water, which causes the brine to be stratified due to the density difference, that is, the density of the lower brine is greater than that of the upper brine. The salt concentration difference formed by this stratification directly affects the regeneration efficiency of the resin; 2) For areas with low temperatures, the less concentrated part of the stratified brine may freeze; 3) The salt dissolving rate is slow. For example, in areas with high water hardness, the slow salt dissolving rate makes the solid salt concentration insufficient, which will greatly reduce the resin regeneration efficiency. After multiple cycles, the water used by users in the later stages of the set water production cycle may be hard water, affecting the user experience. Summary of the invention

[0070] See also Figure 1 , Figure 1 The schematic diagram of the structure of the solid salt dissolution aid for a salt box in one embodiment of the present invention is shown. The solid salt dissolution aid for a salt box provided in one embodiment of the present invention comprises a salt storage portion 110, a support portion 120 for supporting the salt storage portion 110, and a limit portion 130 for limiting the position of the salt storage portion 110; the wall 110a in the salt storage portion 110 for contacting the solid salt is concave-convex and has a plurality of liquid holes 110b, wherein the aperture of the liquid hole 110b is smaller than the particle diameter of the solid salt. It should be noted that Figure 1 , Figure 2 The upper and lower surfaces of the wall 110 a in the salt storage portion 110 for contacting the solid salt are both concave-convex surfaces.

[0071] As an example, the liquid holes 110b can be circular holes, square holes, or elongated holes. In addition, the apertures of the liquid holes 110b are consistent and evenly distributed. Regarding the specific distribution of the liquid holes 110b, the salt storage portion 110 has multiple groups of liquid holes 110b, and two adjacent groups of liquid holes 110b are staggered to increase the dissolution rate of the solid salt.

[0072] The solid salt dissolution-aiding component 100 for a salt box as described above can be applied to the salt box of a water softener. The support portion 120 supports the salt storage portion 110 in the salt box and fixes the solid salt dissolution-aiding component 100 through the cooperation of the limiting portion 130, thereby effectively ensuring that the solid salt stacking position is higher than the bottom of the salt box. Due to the density difference between salt and water, the salt dissolved in the upper part of the salt box moves downward all the time, which will increase the concentration difference between the upper and lower parts of the salt box and thus accelerate the salt dissolution rate, and will also keep the dissolved salt in a state of motion and diffusion until the salt concentration is saturated, which can avoid the problem of freezing in areas with low temperatures, and can also avoid the stratification of brine due to density difference, thereby improving the regeneration efficiency of the resin. In addition, the wall 110a in the salt storage section 110 for contacting the solid salt is concave-convex, which can increase the number of liquid holes 110b, thereby increasing the contact surface area between the solid salt and the water in the salt box, accelerating the dissolution of the solid salt, making the salt water concentration more uniform, and improving the regeneration efficiency of the resin, thereby improving the performance of the water softener.

[0073] In some embodiments of the present invention, the wall 110a in the salt storage portion 110 for contacting the solid salt is wavy (see Figure 1 It can be understood that the wall 110a in the salt storage portion 110 for contacting the solid salt includes a plurality of wavy protrusions or serrated protrusions adjacent to each other. Correspondingly, each group of liquid holes 110b is distributed along the extension direction of the corresponding wavy protrusion or serrated protrusion.

[0074] like Figure 2 As shown, in some embodiments of the present invention, the support portion 120 includes: support ribs 121 arranged on the salt storage portion 110, and the support ribs 121 extend along the edge of the salt storage portion 110 and are connected end to end. The support portion 120 of this type of structure can improve the support strength of the salt storage portion 110.

[0075] Optionally, the supporting ribs 121 may be provided on the salt storage portion 110 in an integrated manner. Figure 1 As shown, the opening and closing hole 110c in the salt storage portion 110 has a larger aperture than the liquid through hole 110b, which facilitates the upper and lower film discharge of the mold.

[0076] Furthermore, if Figure 2 As shown, the support part 120 further includes: a plurality of support columns 122 arranged on the salt storage part 110, the plurality of support columns 122 extend in the same direction, and the support ribs 121 are arranged around the plurality of support columns 122. The support columns 122 can increase the support strength of the salt storage part 110, ensuring that the salt storage part 110 can bear a certain weight of solid salt.

[0077] Optionally, the support column 122 is a hollow structure, and can be provided on the salt storage portion 110 by an integrated molding method or a threaded connection method. The embodiment of the present invention does not specifically limit the number of the support columns 122, and for example, four support columns can be provided.

[0078] Furthermore, if Figure 2 As shown, in some embodiments of the present invention, the support portion 120 further includes: a plurality of reinforcing ribs 123 disposed on the salt storage portion 110, each reinforcing rib 123 being connected between the support rib 121 and the corresponding support column 122 or between two corresponding adjacent support columns 122. The reinforcing rib 123 can increase the connection strength of the support rib 121 and the support column 122 on the salt storage portion 110.

[0079] Optionally, the reinforcing ribs 123 can be fixed by integrated molding. Regarding the distribution of the reinforcing ribs 123, the reinforcing ribs 123 used to connect the support columns 122 and the support ribs 121 in any two adjacent support columns 122 are located on different sides, which can improve the reinforcing effect of the support ribs 121.

[0080] Furthermore, if Figure 2 As shown, in some embodiments of the present invention, a liquid passage 123a is provided on one end of the reinforcing rib 123 away from the salt storage portion 110. In this way, the flow rate of the solution in the space enclosed between the supporting rib 121 and the salt storage portion 110 can be increased, which is beneficial to the dissolution of the solid salt.

[0081] Optionally, the liquid passage 123a may be a U-shaped groove, a semicircular groove, a rectangular groove, a trapezoidal groove or the like.

[0082] Based on the premise that the support portion 120 includes the support ribs 121, Figure 1 As shown, in some embodiments of the present invention, the salt storage part 110 includes: a salt storage plate 111 and a connecting rib 112 disposed on the periphery of the salt storage plate 111 and connected end to end; the salt storage plate 111 is concave-convex and has a liquid through hole 110b; the supporting rib 121 is connected to the connecting rib 112 and the protruding directions of the two are opposite. In this way, the connection of the supporting rib 121 is facilitated.

[0083] Optionally, the salt storage plate 111 and the connecting ribs 112 may be connected by integrated molding or welding.

[0084] Based on the support portion 120 and the salt storage portion 110 of the above structure, the embodiment of the present invention provides two examples of the structure of the limiting portion 130:

[0085] In the first example, the support rib 121 has a first installation limit surface and a second installation limit surface (not shown in the drawings), and the first installation limit surface and the second installation limit surface cooperate to form a limit portion 130.

[0086] It should be noted that the structure of the first installation limit surface is adapted to the outer contour of the resin tank 300, and the structure of the second installation limit surface is adapted to the outer contour of the salt well 410. After the resin tank 300 and the salt well 410 are installed in the salt box, the solid salt dissolution aid 100 can be limited to between the shell 200 of the salt box and the fat tank and the salt well 410 by cooperating with the first installation limit surface and the second installation limit surface, so as to avoid Figure 3 The solid salt dissolution-promoting component 100 shown shakes in the left and right directions. When assembling the water softener, the solid salt dissolution-promoting component 100 is first placed at the bottom of the shell 200 of the salt box, and then the resin tank 300 and the salt well 410 are placed at the bottom of the shell 200 of the salt box. The first installation limit surface and the second installation limit surface of the solid salt dissolution-promoting component 100 are matched with the resin tank 300 and the salt well 410 respectively, thereby achieving the fixation of the solid salt dissolution-promoting component 100.

[0087] As described above, the limiting portion 130 is provided on the support rib 121 in the form of two installation limiting surfaces. The matching area between the installation limiting surface and the salt well 410 and the resin tank 300 can be increased by increasing the height of the support rib 121, thereby improving the installation firmness of the solid salt dissolution aid 100 in the shell 200 of the salt box, and correspondingly increasing the distance between the salt storage portion 110 and the bottom of the salt box, which can further accelerate the dissolution of the solid salt. Of course, when used, the salt storage portion 110 can also have the first installation limiting surface and the second installation limiting surface described above.

[0088] Optionally, the first installation limit surface and the second installation limit surface are both arc-shaped. The salt well 410 and the resin tank 300 are usually cylindrical, and the first installation limit surface and the second installation limit surface of the arc structure are more consistent with the outer contours of the salt well 410 and the resin tank 300, so that the limiting effect of the salt well 410 and the resin tank 300 on the solid salt dissolution aid 100 can be improved.

[0089] Optionally, the first installation limit surface and the second installation limit surface are located on the same side. In this way, when assembling the water softener, the salt well 410 and the resin tank 300 can be installed on the same side (see Figure 3 ), which can make the structure of the water softener compact.

[0090] Example (2): Figure 1 As shown, the limiting portion 130 includes: a first limiting rib 131 and a second limiting rib 132 which are respectively arranged on the first outer surface and the second outer surface of the connecting rib 112 .

[0091] Optionally, the first outer surface and the second outer surface of the support rib 121 are both configured as a two-layer step structure, and the first limiting rib 131 and the second limiting rib 132 are respectively connected to the outer edge of the lower step surface of the corresponding two-layer step structure. Figure 1 As shown, a plurality of reinforcing plates are arranged at intervals along the direction of the step structure to improve the overall strength of the salt storage portion 110. The reinforcing plates may be right-angled plates, wherein one right-angled side of the right-angled plate is connected to the lower step surface (e.g., integrally formed or welded), and the other right-angled side is connected to the side surface between the lower step surface and the upper step surface (e.g., integrally formed or welded).

[0092] Optionally, the first limiting rib 131 and the second limiting rib 132 are respectively formed integrally with the connecting rib 112 .

[0093] Alternatively, if Figure 1 As shown, the first limiting rib 131 and the second limiting rib 132 are both arc-shaped. The salt well 410 and the resin tank 300 are usually cylindrical, and the first limiting rib 131 and the second limiting rib 132 of the arc structure are more consistent with the outer contours of the salt well 410 and the resin tank 300, so that the limiting effect of the salt well 410 and the resin tank 300 on the solid salt dissolution component 100 can be improved. Among them, the first outer surface and the second outer surface of the connecting rib 112 are respectively set to the same arc structure as the outer contours of the salt well 410 and the resin tank 300, so as to make the structure of the solid salt dissolution component 100 compact.

[0094] Alternatively, if Figure 1 As shown, the first limiting rib 131 and the second limiting rib 132 are both located on the same side. In this way, when assembling the water softener, the salt well 410 and the resin tank 300 can be installed on the same side (see Figure 3 ), which can make the structure of the water softener compact.

[0095] On the other hand, an embodiment of the present invention further provides a salt box, such as Figure 3 and Figure 4 As shown, the salt box includes: a shell 200 and any of the solid salt dissolution-aiding components 100 described above; the salt storage portion 110 of the solid salt dissolution-aiding component 100 is supported on the bottom of the shell 200 by a support portion 120, and the salt storage portion 110 is also limited in the shell 200 by a limiting portion 130.

[0096] The salt box as described above can be applied to a water softener. The support part 120 supports the salt storage part 110 in the salt box and fixes the solid salt dissolving aid 100 through the cooperation of the limiting part 130. In this way, the solid salt stacking position can be effectively ensured to be higher than the bottom of the salt box. Due to the density difference between salt and water, the salt dissolved in the upper part of the salt box moves downward all the time, which will increase the concentration difference between the upper and lower parts of the salt box and thus accelerate the salt dissolving rate, and also make the dissolved salt always in a state of movement and diffusion until the salt concentration is saturated, which can avoid the problem of freezing in areas with low temperatures, and can also avoid the stratification of salt water due to density difference, thereby improving the regeneration efficiency of the resin. In addition, the wall 110a in the salt storage part 110 for contacting the solid salt is concave and convex, which can increase the number of liquid holes 110b, thereby increasing the contact surface area between the solid salt and the water in the salt box, accelerating the dissolution of the solid salt, making the salt water concentration more uniform, and improving the regeneration efficiency of the resin, thereby improving the performance of the water softener.

[0097] In some embodiments of the present invention, Figure 4 As shown, a salt well installation groove 200a and a resin tank installation groove 200b are also provided on the bottom of the housing 200, and both the salt well installation groove 200a and the resin tank installation groove 200b are adjacent to the solid salt dissolution-promoting component 100, so as to limit the solid salt dissolution-promoting component 100 through the cooperation of the limiting portion 130. The lower end of the salt well 410 can be fixed in the salt well installation groove 200a, and the lower end of the resin tank 300 can be fixed in the resin tank installation groove 200b, so that the salt well 410 and the resin tank 300 can be installed in the salt box, thereby making the structure of the water softener compact.

[0098] Furthermore, if Figure 4 As shown, in some embodiments of the present invention, the salt well installation groove 200 a and the resin tank installation groove 200 b are both adjacent to the solid salt dissolution-promoting component 100 , so that the solid salt dissolution-promoting component 100 is limited by the cooperation of the limiting portion 130 . When assembling the water softener, first place the solid salt dissolving component 100 into the bottom of the salt box shell 200, then place the resin tank 300 into the salt box, with the lower end of the resin tank 300 fixed in the resin tank mounting groove 200b, to prevent the resin tank 300 from moving left and right, forward and backward, and then place the salt well 410 into the salt box shell 200, with the lower end of the salt well 410 fixed in the salt well mounting groove 200a. After the resin tank 300 and the salt valve 420 are installed, the first installation limit surface of the limit portion 130 cooperates with the resin tank 300 and the second installation limit surface cooperates with the salt well 410, thereby limiting the position of the solid salt dissolving component 100. In this way, the installation of the solid salt dissolving component 100, the salt well 410 and the resin tank 300 is realized, making the disassembly and assembly of the water softener more convenient.

[0099] Specifically in some embodiments of the present invention, Figure 4As shown, an annular protrusion 210 is provided on the bottom of the housing 200, and the central cavity of the annular protrusion 210 constitutes a salt well installation groove 200a. The annular protrusion 210 can be provided on the bottom of the housing 200 by an integrated molding method or a welding method.

[0100] Specifically in some embodiments of the present invention, Figure 4 As shown, a plurality of mounting protrusions 220 are arranged on the bottom of the housing 200 and are distributed at intervals along the circumferential direction. The plurality of mounting protrusions 220 cooperate with each other to form a resin tank mounting groove 200 b.

[0101] Optionally, the mounting protrusions 220 are provided on the bottom of the housing 200 by integrated molding or welding. The number of the mounting protrusions 220 is not specifically limited in the embodiment of the present invention. For example, four mounting protrusions 220 may be evenly provided.

[0102] Alternatively, if Figure 4 As shown, the bottom of the housing 200 also has an inverted trapezoidal receiving groove, and the mounting protrusion 220 is arranged between the receiving groove and the bottom of the housing 200. In this way, the bottom of the grease tank mounting groove 200b can be placed in the receiving groove and limited by the mounting protrusion 220.

[0103] Another embodiment of the present invention further provides a water softener, such as Figure 3 and Figure 4 As shown, the water softener includes: a salt valve assembly 400, a resin tank 300 and a salt box as described in any of the above items; the salt valve assembly 400 and the resin tank 300 are both arranged in the shell 200 of the salt box; the limiting portion 130 of the solid salt dissolving component 100 of the salt box is used to limit the salt storage portion 110 of the solid salt dissolving component 100 between the resin tank 300 and the shell 200 and between the salt well 410 of the salt valve assembly 400 and the shell 200.

[0104] It should be noted that if Figure 3 As shown, the salt valve assembly 400 includes: a salt well 410 and a salt valve 420 disposed in the salt well 410 .

[0105] In the water softener as described above, the support part 120 supports the salt storage part 110 in the salt box and fixes the solid salt dissolving aid 100 through the cooperation of the limiting part 130, so that the solid salt stacking position can be effectively ensured to be higher than the bottom of the salt box. Due to the density difference between salt and water, the salt dissolved in the upper part of the salt box moves downward all the time, which will increase the concentration difference between the upper and lower parts of the salt box and thus accelerate the salt dissolving rate, and also make the dissolved salt always in a state of movement and diffusion until the salt concentration is saturated, which can avoid the problem of freezing in areas with low temperatures, and can also avoid the stratification of salt water due to density difference, thereby improving the regeneration efficiency of the resin. In addition, the wall in the salt storage part 110 for contacting the solid salt is concave and convex, which can increase the number of liquid holes 110b, thereby increasing the contact surface area between the solid salt and the water in the salt box, accelerating the dissolution of the solid salt, making the salt water concentration more uniform, and improving the regeneration efficiency of the resin, thereby improving the performance of the water softener.

[0106] In some embodiments of the present invention, Figure 2 As shown, the support portion 120 of the solid salt dissolution aid 100 includes: a support rib 121 arranged on the salt storage portion 110, the support rib 121 extends along the edge of the salt storage portion 110 and is connected end to end; wherein, the support rib 121 has a first installation limit surface adapted to the outer contour of the resin tank 300 and a second installation limit surface adapted to the outer contour of the salt well 410, and the first installation limit surface and the second installation limit surface cooperate to form a limit portion 130. It can be understood that the remaining surface of the support rib 121 is adapted to the inner contour structure of the shell 200.

[0107] In other embodiments of the present invention, Figure 1 As shown, the salt storage part 110 includes: a salt storage plate 111 and a connecting rib 112 arranged on the periphery of the salt storage plate 111 and connected end to end; the salt storage plate 111 is concave-convex and has a liquid through hole 110b; the connecting rib 112 is connected to the supporting rib 121 and the protruding directions of the two are opposite; the limiting part 130 includes: a first limiting rib 131 and a second limiting rib 132 respectively arranged on the first outer surface and the second outer surface of the connecting rib 112; the outer contours of the first limiting rib 131 and the second limiting rib 132 are respectively adapted to the outer contours of the resin tank 300 and the salt well 410.

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