Background

With the improvement of living standard, people have higher and higher requirements on the used water quality, for example, the hardness of washing water is not too high, and correspondingly, a water softener which can soften water body by using resin to remove easily-scaling components (mainly calcium and magnesium ions) is more and more popular. Wherein, when the water softener is in use, the failed resin needs to be regenerated by adding strong brine.

In the existing water softeners, solid salt is generally directly placed at the bottom of a salt box of the water softener to be stacked, and the solid salt is dissolved by adding water before regeneration to prepare strong brine required by regeneration. However, the salt dissolving mode causes the salt dissolving speed to be slow, the brine can not reach a saturated state within a long time, the regeneration efficiency of the resin in the regeneration process is low, the periodic water production amount of the water softener is small, the regeneration frequency is too frequent, and the service life is short; meanwhile, the utilization rate of the solid salt is low, so that the waste of the regenerated salt is caused, and the use cost of the salt box is too high.

An embodiment of the present invention provides a salt box, as shown in fig. 1 to 4, including: the device comprises a box body 100, a barrier piece 200 and a solid salt dissolution assisting piece; as shown in fig. 5 and 7, the barrier 200 is disposed in the case 100 to divide the inner cavity of the case 100 into the resin tank installation chamber 110 and the dissolution aid installation chamber 120 in the horizontal direction of the case 100; referring to fig. 1 and 4, the solid salt dissolution aid is disposed in the dissolution aid mounting chamber 120, the solid salt dissolution aid includes a salt storage portion 310, the salt storage portion 310 has a plurality of salt dissolution holes 310a (see fig. 1 and 3), and a predetermined distance is provided between the salt storage portion 310 and the bottom of the dissolution aid mounting chamber 120.

It is understood that, referring to fig. 1 and 4, the resin tank 400 is installed in the resin tank installation chamber 110 of the cabinet 100.

As an example, in some embodiments of the present invention, the preset distance is 0.5 to 1 time (for example, may be set to 0.5 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, 1.0 times, etc.) of a height of the brine in the box 100, where the height of the brine is a height of the brine after the solid salt dissolution aid and the salt well are installed in the box 100. In this way, the dissolution rate of the solid salt A can be ensured.

As an example, the salt dissolving holes 310a may be circular holes, square holes, or long holes. In addition, the size of the salt-dissolving pores 310a is uniform and evenly distributed. Regarding the specific distribution of the salt dissolving holes 310a, the salt storing part 310 has a plurality of groups of salt dissolving holes 310a, and two adjacent groups of salt dissolving holes 310a are distributed in a staggered manner to increase the dissolution rate of the solid salt a.

The salt box can be applied to a water softener, the salt storage part 310 of the solid salt dissolving-assisting part can stack solid salt A higher than the bottom of the salt box due to the preset distance between the salt storage part and the bottom of the dissolving-assisting part installation chamber 120, and the dissolved salt at the upper part in the salt box can move downwards all the time due to the density difference between salt and water, so that the concentration difference between the upper part and the lower part in the salt box can be increased, the salt dissolving speed can be accelerated, the dissolved salt can be in a movement diffusion state all the time until the salt concentration is saturated, the problem that the ice is possibly generated in a low-temperature area can be avoided, and the problem that the brine is layered due to the density difference can be avoided, so that the regeneration efficiency of resin can be improved. In addition, the blocking member 200 can block water in the dissolution assisting member mounting chamber 120 from flowing into the resin tank mounting chamber 110, and ensure that all water in the salt tank is covered by the solid salt a, so that the salt dissolving speed can be further increased, and the salt water can reach a saturated state, otherwise, the salt dissolving speed is slowed, and the salt water is difficult to reach the saturated state; meanwhile, the blocking member 200 may block a user from observing the resin tank 400 from the outside, and may also play a decorative role, improving the aesthetic property of the salt box.

In some embodiments of the present invention, as shown in fig. 5 to 9, the barrier 200 is integrally formed with a salt well 210, and the bottom of the salt well 210 has a water passage 210a communicating with the dissolution aid mounting chamber 120. It will be appreciated that referring to fig. 1 to 3 and 8 to 10, a salt valve 500 is installed in the salt well 210, the salt valve 500 is used for injecting water into the hydrotrope installation chamber 120 of the salt tank and sucking salt water from the hydrotrope installation chamber 120 into the resin tank 400, and the salt valve 500 also has a liquid level control function, i.e., is capable of controlling the amount of water injected into the hydrotrope installation chamber 120 and controlling the amount of water sucked from the salt tank. The salt well 210 is not required to be fixed in the box body 100 through mounting parts (such as screws), so that the assembly efficiency of the whole machine is improved, and the cost is reduced. Of course, in other embodiments of the present invention, referring to fig. 10 and 11, the salt well 210 and the barrier 200 may be separately disposed in the flux mounting chamber 120.

Optionally, at least one water slit is opened at the bottom of the salt well 210 to form a water passage 210 a. The number of the water gaps may be multiple, and the water gaps are distributed at intervals along the length direction of the salt well 210.

In some embodiments of the invention, the barrier 200 is integrally molded with the case 100. Thus, the assembly efficiency of the salt box can be improved.

Of course, in other embodiments of the present invention, the blocking member 200 is inserted into the case 100. In this manner, the barrier 200 may be replaced. Specifically, two side walls oppositely distributed in the box body 100 are respectively provided with a mounting rib; the mounting ribs are provided with first inserting grooves extending along the height of the box body 100, and two ends of the barrier piece 200 are respectively inserted into the corresponding first inserting grooves; alternatively, two ends of the blocking member 200 are respectively provided with a second insertion groove extending along the height of the box body 100, and the mounting ribs are inserted into the corresponding second insertion grooves. Further, there is a first seal between the bottom of the first bayonet groove and the end of the barrier 200, or a second seal between the bottom of the second bayonet groove and the mounting rib. The first seal or the second seal may block the water or brine inside the fluxing member mounting chamber 120 from channeling into the resin tank mounting chamber 110. Optionally, the first sealing member is adhered to or integrally formed on the groove bottom of the first insertion groove or the blocking member 200; the second sealing element is adhered to or integrally formed on the groove bottom or the mounting rib of the second inserting groove.

In some embodiments of the invention, the barrier 200 is a straight plate structure as shown in fig. 8, 9 or an arcuate plate structure as shown in fig. 2, 3, and 5-7 that is convexly curved toward the flux-assist mounting chamber 120. It will be appreciated that, referring to fig. 2 and 3, the arcuate plate structure conforms to the contour of the resin tank 400. Compared with the barrier member 200 having a straight plate structure, the barrier member 200 having an arc-shaped plate structure may be distributed around the resin tank 400, so that the salt storage area of the salt storage portion 310 may be increased, and the salt storage amount may be increased.

In some embodiments of the present invention, as shown in fig. 4, the solid salt solubilizing aid further comprises: and a support part 320, wherein the support part 320 is used for supporting the salt storage part 310 on the bottom of the dissolution-assistant fitting chamber 120. In this way, the fixation of the solid salt dissolution aid in the tank 100 is facilitated.

In some embodiments of the present invention, as shown in fig. 4, the supporting portion 320 includes: a plurality of support columns disposed on the salt storage part 310, the plurality of support columns extending in the same direction. Alternatively, the supporting column is a hollow structure, and may be disposed on the salt storage portion 310 in an integrally molded manner or in a threaded manner. The number of the support columns is not particularly limited in the embodiment of the present invention, and for example, 4 support columns may be provided.

Further, in some embodiments of the present invention, the surface of the salt reservoir 310 for contacting the solid salt a is a concave-convex surface. Thus, the contact area between the salt reservoir 310 and the solid salt a can be increased, and the dissolution of the solid salt a can be accelerated. Optionally, the concave-convex surface is a wavy surface or a zigzag surface to further increase the contact area of the salt storing part 310 with the solid salt a. It will be appreciated that the salt reservoir 310 of the plate-like structure is provided with a plurality of wavy projections or serrated surfaces next to each other to form wavy or serrated surfaces correspondingly.

Of course, in other embodiments of the present invention, the salt reservoir 310 is a pocketed structure. The salt storing part 310, which is an exemplary pocket structure, is provided with a first end and a second end which are oppositely distributed, the first end is provided with an opening, and the second end is a closed end. Wherein, the second end of the salt storing part 310 may be provided in an arc structure protruding outward to increase the salt storing volume. The salt storage part 310 may be formed in a cylindrical shape, a square cylindrical shape, or the like.

Alternatively, the material of the salt storing portion 310 of the pocket-shaped structure may be PPS (polyphenylene sulfide) plastic, and the embodiment of the present invention does not specifically limit the material of the salt storing portion 310 as long as the salt storing portion has certain toughness and strength. Wherein, the salt storing part 310 can be prepared by weaving or splicing a plurality of woven fabrics.

Further, in some embodiments of the present invention, the salt storing part 310 of the pocket structure may be suspended in the case 100 through its own hole, for example, at any corner of the upper part of the case 100. Correspondingly, a mounting member may be provided on an inner wall of the cabinet 100 to hang the salt storage part 310 of the pocket structure. In particular, the mounting is a hook or a beam. Wherein, the number of couple can be set to two, and these two couples symmetric distribution.

In some embodiments of the present invention, as shown in fig. 1 and 2, the salt reservoir 310 covers a cross-section of the flux-assist mounting chamber 120. Thus, the dissolution rate of the solid salt A can be increased. To illustrate that this arrangement can increase the dissolution rate of the fast solid salt a, three comparative experiments were performed as follows:

comparative experiment one, conducted as shown in fig. 12, was to dissolve the solid salt a directly in beaker B; a second comparative experiment was conducted as shown in fig. 16, in which a solid salt a was wrapped with a string bag C and then placed on the top of the liquid surface of a beaker B to dissolve the salt; a third comparative experiment was conducted as shown in FIG. 20, in which the solid salt A was wrapped in a string bag C having the same size as the opening of the beaker B, and then placed on the top of the liquid surface of the beaker B to dissolve the salt. The density of each brine was determined by sampling the brine from beaker B in three experiments at intervals to give the following data:

TABLE 1

It should be noted that the comparative experiment one corresponds to the prior art solution of placing the solid salt a at the bottom of the tank 100 shown in fig. 13 and 14, the comparative experiment two corresponds to the solution of not covering all the salt storing parts 310 at the cross section of the dissolution aid mounting chamber 120 shown in fig. 17 and 18, and the comparative experiment two corresponds to the solution of covering all the salt storing parts 310 at the cross section of the dissolution aid mounting chamber 120 shown in fig. 21 and 22. As can be seen from table 1, the third comparative experiment has the largest salt dissolving rate, the second comparative experiment has the second salt dissolving rate, and the first comparative experiment has the slowest salt dissolving rate, i.e., the salt storage part 310 covers the cross section of the dissolution aid installation chamber 120, so that the dissolution rate of the solid salt a can be increased. Fig. 19 and 23 are schematic diagrams showing the solid salt a spreading after covering a part of the water surface of the beaker B and the whole water surface of the beaker B, respectively, and it can be illustrated again that the salt storage part 310 covers the cross section of the dissolution aid mounting chamber 120 to accelerate the dissolution rate of the solid salt a. In addition, as shown in fig. 15, if the solid salt a is directly stacked at the bottom of the salt tank, since the density of the brine is higher than that of water, the brine near the solid salt a has the highest density and sinks to the bottommost part during the salt dissolving process, and the density at the upper layer is the lowest, so that the dissolved salt stratification phenomenon occurs.

Another embodiment of the present invention also provides a water softener, as shown in fig. 1 to 4, including the above-mentioned salt tank.

In the water softener, the salt storage part 310 of the solid salt dissolution assisting part has a preset distance with the bottom of the dissolution assisting part mounting chamber 120, so that the solid salt A can be stacked at a position higher than the bottom of the salt box, and the dissolved salt at the upper part in the salt box can move downwards all the time due to the density difference between the salt and the water, so that the concentration difference between the upper part and the lower part in the salt box can be increased, the salt dissolving speed can be accelerated, the dissolved salt can be in a movement diffusion state all the time until the salt concentration is saturated, the problem of icing in a low temperature region can be avoided, and the problem of layering of the salt water due to the density difference can be avoided, so that the regeneration efficiency of the resin can be improved. In addition, the blocking member 200 can block water in the dissolution assisting member mounting chamber 120 from flowing into the resin tank mounting chamber 110, and ensure that all water in the salt tank is covered by the solid salt a, so that the salt dissolving speed can be further increased, and the salt water can reach a saturated state, otherwise, the salt dissolving speed is slowed, and the salt water is difficult to reach the saturated state; meanwhile, the barrier 200 may block the user from observing the resin tank 400 from the outside, and may also play a role of decoration, improving the aesthetic property of the water softener.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
