Description

Technical Field

[0001] The invention relates to a water softener and also to a cleaning machine using the water softener. Background Art

[0002] Existing dishwashers usually have a softening function, that is, the domestic water is softened by a water softener before entering the dishwasher cavity for tableware washing, to prevent excessive Ca and Mg ions from causing scale to form on the tableware and the inner tank. Ion exchange resin is usually used in water softeners to soften water. After a certain period of softening, the ion exchange resin will reach a "saturated" state of calcium and magnesium ions. At this time, it needs to be regenerated by softening salt to release wastewater saturated with Ca and Mg ions and discharge it.

[0003] Generally speaking, a resin chamber for placing ion exchange resin is provided in a water softener. The water entering the softener flows through a certain channel and squeezes into the resin chamber. After being softened by the ion exchange resin in the resin chamber, the water flows out from the outlet of the resin chamber and then enters the water inlet channel of the dishwasher and the inner tank of the dishwasher to complete the tableware washing process. This can effectively prevent the scaling of the inner tank side wall and the surface of the tableware, and is also beneficial to the life of the parts. However, the existing resin chambers are all simple cylindrical structures with a relatively simple structure. When water flows through the resin chamber, it often cannot fully contact with the ion exchange resin in the resin chamber, and the corresponding resin particles cannot absorb Ca and Mg ions well. The water flow may even "squeeze" the loose resin to one side, forming a "cavity-like" channel with less resistance and passing through it, so the softening effect is greatly reduced. The resin cavity in the existing water softener is usually in a static state for a long time, and the resin particles inside are basically static. Therefore, it is difficult to restore the uniform distribution of the resin by itself, that is, the "cavity-like" channel formed by the resin is not easy to restore. Long-term flushing of water flow will aggravate this problem, resulting in softening and reduced regeneration efficiency of the water softener after long-term use. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a water softener which can divide the resin cavity into multiple channels, thereby alleviating the situation that channels with less resistance are formed due to water flow impact and improving the degree of full contact between ion exchange resin and water flow.

[0016] Preferably, the first meshing teeth extend vertically along the inner peripheral wall of the resin cavity, and the upper end and the lower end of the second resin cylinder are respectively provided with second meshing teeth.

[0032] The present invention is further described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 3 As shown, the water softener in this embodiment includes a main body 1 having a resin cavity 11, a water inlet 12 is formed at the bottom of the resin cavity 11, and a water outlet 13 is formed at the top of the resin cavity 11. Specifically, the main body 1 includes a base 101, an upper cover 102 covering the top of the base 101, and a lower cover 103 arranged below the base 101. An upwardly open cavity is formed in the base 101, and divergently distributed flow holes are opened at the bottom of the cavity. The upper cover 102 covers the cavity from above and together with the cavity constitutes the resin cavity 11, and a water outlet 13 facing the cavity is formed on the upper cover, and a water outlet channel connected to the water outlet 13 is also formed on the upper cover 102, and the water outlet channel can be connected to the water supply port of other products, thereby providing softened water for the product. A water receiving area is formed on the lower cover 103 below the resin cavity 11, and the flow hole at the bottom of the cavity forms a water inlet 12 of the resin cavity 11. After water enters the receiving area in the lower cover 103 from the water inlet channel in the main body 1, it enters the resin cavity 11 through the water inlet 12 based on the water pressure.

[0034] A plurality of resin barrels 2 extending vertically are provided in the resin chamber 11, and the top, bottom and side surfaces of these resin barrels 2 are provided with flow holes for water to flow through. Each resin barrel 2 is filled with ion exchange resin to soften the water. These resin barrels 2 divide the space in the resin chamber 11 from the horizontal plane direction, and divide the space in the resin chamber 11 into resin areas of multiple channels. The amount of ion exchange resin in each resin barrel 2 is small, so that the water flow entering the resin chamber 11 is more likely to contact with the resin, thereby improving the degree of sufficient contact. At the same time, these resin barrels 2 divert the water entering the resin chamber 11 and enter each resin barrel 2, and the impact force on the resin in the resin barrel 2 is relatively small, thereby alleviating the situation where a channel with less resistance is formed due to the impact of water flow.

[0035] In this embodiment, the space in the resin chamber 11 is also divided in the vertical direction to further alleviate the situation of forming a channel with less resistance due to the impact of water flow, and further improve the degree of full contact between the ion exchange resin and the water flow. Specifically, a first resin box 3 is also provided in the resin chamber 11, and the first resin box 3 is provided below each resin cylinder 2, and at least the top and bottom surfaces of the first resin box 3 are provided with flow holes. In order to ensure the amount of resin and make the water fully contact with sufficient resin, the peripheral side surface of the first resin box 3 matches the inner peripheral surface of the resin chamber 11. Usually, the cross section of the resin chamber 11 is circular, and the peripheral side surface of the first resin box 3 is also circular.

[0036] Furthermore, a second resin box 5 is provided in the resin cavity 11, and the second resin box 5 is provided above each resin cylinder 2, and at least the top and bottom surfaces of the second resin box 5 are provided with flow holes. The peripheral side surface of the first resin box 3 matches the inner peripheral surface of the resin cavity 11. In this way, the resin cavity 11 is divided into three layers from the resin direction. Each resin box and each resin cylinder 2 forms an independent water softening unit, which greatly improves the degree of sufficient contact between water and the resin in each water softening unit, and the channel with less resistance formed in each water softening unit will also be greatly weakened, and the recovery ability is strong.

[0037] If all the resin boxes and resin cylinders 2 are in a stationary state, although the situation of forming a channel with less resistance due to water flow impact can be alleviated to a certain extent, this situation is still inevitable. In this way, how to improve the ability to restore the uniform distribution state of the resin in each water softening unit and further avoid the situation where the resin forms a "cavity-like" channel. The following further technical solutions are proposed in this embodiment.

[0038] The water softener also includes a driving mechanism for driving the first resin box 3 and each resin barrel 2 to rotate, and the second resin barrel 22 can be connected to the first resin barrel 21 through a linkage structure. In this way, the driving mechanism drives the first resin box 3, the second resin box 5, and each resin barrel 2 to rotate, so that the resins in the first resin box 3, the second resin box 5, and each resin barrel 2 are in a dynamic state, and the resin improves its ability to recover its uniform distribution state based on its dynamic state. Even if a weaker "cavity-like" channel state occurs during the water softening process, it can quickly recover its uniform distribution state based on the movement of the resin, thereby improving the full contact between water and resin and improving the water softening efficiency.

[0039] The structure of the driving mechanism is specifically set based on a specific driving strategy, for example, the driving mechanism may include a plurality of drivers for respectively driving the first resin box 3 and each resin cylinder 2. However, this structure occupies a large volume, is costly, and has a complex assembly structure.

[0040] In this embodiment, only one motor 4 is provided to drive the first resin box 3, the second resin box 5 and each resin cylinder 2. Such a driving mechanism has low cost, occupies little space and is easy to assemble.

[0041] Specifically, the resin cylinder 2 includes a first resin cylinder 21 located in the center of the resin cavity 11 and a plurality of second resin cylinders 22 distributed around the first resin cylinder 21. Based on the first resin cylinder 21, the central space in the resin cavity 11 is fully utilized, more resin particles can be accommodated, the resin capacity and compactness of the central cavity are increased, and the softening efficiency is improved.

[0042] In order to facilitate assembly and improve the rotation stability of each resin barrel 2 and the first resin box 3 under the operation of the driving mechanism, the first resin barrel 21 is connected to the top surface of the first resin box 3. The first resin barrel 21 can be connected to the top surface of the first resin box 3 using an existing connection structure, or it can be integrally formed on the top surface of the first resin barrel 21. When the first resin barrel 21 is integrally formed on the top surface of the first resin barrel 21, there is no need to set the bottom surface of the first resin barrel 21, and a through-flow hole is also opened on the top surface of the first resin barrel 21 at a position corresponding to the setting of the first resin barrel 21, so that the first resin barrel 21 and the first resin box 3 are connected through the through-flow hole. In this way, the water output from the first resin box 3 can enter the first resin barrel 21. A first connecting shaft 31 is provided on the top surface of the first resin box 3 corresponding to each second resin barrel 22, and the first connecting shaft 31 is penetrated in the bottom surface of the corresponding second resin barrel 22. Based on the first connecting shaft 31, each second resin barrel 22 can be stably and vertically placed above the first resin box 3. The driving end of the driving mechanism is connected to the first resin box 3. The driving mechanism is arranged on the lower cover of the main body 1. In this embodiment, the driving mechanism adopts a motor 4. A device groove can be arranged on the lower cover to be recessed upwards. The motor 4 can be embedded in the device groove. The driving shaft passes through the lower cover and is connected to the first resin box 3. In order to prevent water from entering the motor 4, a sealing ring can be arranged at the part where the driving shaft passes. In order to facilitate the driving assembly of the first resin box 3 on the motor 4, the assembly difficulty is reduced. A first shaft rod 32 is convexly arranged upwardly at the center of the bottom surface of the first resin box 3. A connecting groove 321 opening downwards is arranged in the first shaft rod 32. The cross section of the connecting groove 321 is non-circular. The driving shaft of the motor 4 is inserted into the connecting groove 321, and the cross section of the driving shaft matches the cross section shape of the connecting groove 321. In this way, when the motor 4 is working, the rotation of the driving shaft can drive the first resin box 3 to rotate, and at the same time, the first resin cylinder 21 and the second resin cylinder 22 arranged above the first resin box 3 rotate synchronously with the first resin box 3.

[0043] In order to further realize the self-rotation drive of each second resin barrel 22 and improve the uniform distribution state of the resin in the second resin barrel 22, in this embodiment, a circle of first meshing teeth 111 is provided on the inner circumferential wall of the resin cavity 11, and a second meshing tooth 221 meshing with the first meshing tooth 111 is provided on the side wall of each second resin barrel 22 along the circumferential direction. The first meshing tooth 111 extends vertically along the inner circumferential wall of the resin cavity 11, and the upper and lower ends of the second resin barrel 22 are respectively provided with the second meshing teeth 221. The second meshing teeth 221 at the upper and lower ends of the second resin barrel 22 are both meshed with the first meshing teeth 111 to realize self-rotation, thereby improving the self-rotation stability of the second resin barrel 22. In this way, the second resin barrel 22 can rotate synchronously with the first resin box 3 while also rotating itself, thereby increasing the movement amplitude of the resin in the second resin barrel 22, which is conducive to the rapid recovery of the resin in the second resin barrel 22 to a uniform distribution state.

[0044] A sleeve 51 extends downward from the bottom surface of the second resin box 5, and the sleeve 51 is sleeved on the upper part of the first resin cylinder 21. The sleeve 51 and the upper part of the first resin cylinder 21 are fixedly connected in a tight fit. Based on the connection between the sleeve 51 and the first resin cylinder 21, and the connection between the first resin cylinder 21 and the first resin box 3, when the motor 4 drives the first resin box 3 to rotate, the second resin box 5 can rotate synchronously with the first resin cylinder 21.

[0045] In order to improve the stability of the second resin box 5 rotating with the first resin box 3, a limiting axis 112 extends downward from the top surface of the resin cavity 11, and the limiting axis 112 is penetrated in the top surface of the second resin box 5. In this way, the second resin box 5 can rotate based on the limiting axis 112 as the axis.

[0046] In order to improve the structural stability of the second resin cylinder 22, a second connecting shaft 52 is provided on the bottom surface of the second resin box 5 corresponding to each second resin cylinder 22, and the second connecting shaft 52 is passed through the top surface of the corresponding second resin cylinder 22. In this way, the upper and lower ends of the second resin cylinder 22 are limited based on the first connecting shaft 31 and the second connecting shaft 52. On the one hand, it can maintain a stable vertical state, and on the other hand, it can ensure its stability during rotation.

[0047] In addition, the aforementioned sleeve 51 also extends upward to protrude from the top surface of the second resin box 5, and forms a connection portion 511 on the top surface of the second resin box 5 that is connected to the water outlet 13. The connection portion 511 facilitates docking with the water outlet 13. Water can automatically flow into the water outlet 13 through the sleeve 51. At the same time, the portion of the sleeve 51 located between the top and bottom surfaces of the second resin box 5 closes the connection between the space inside the sleeve 51 and the space inside the second resin box 5, so that the water entering the second resin box 5 must flow back to the position below the sleeve 51 and then pass through the flow holes on the side wall of the first resin cylinder 21 to enter the sleeve 51, and then output to the water outlet 13. In this way, the reflux formed by the water flow in the second resin box 5 can extend the path length of the water contacting the resin, and the water flow with a slightly lower softening degree can be further softened, which can improve the overall softening effect and reliability.

[0048] When the water softener is working, the water flow inside the resin chamber 11 is not fixed, and will form a certain vortex flow state with the rotation of the first resin box 3, the second resin box 5, and each resin cylinder 2. The water flow goes up from the initial state, and when it reaches the second resin box 5, it moves up from the top surface and the side annular gap, then passes through the top surface of the second resin box 5 into the second resin box 5, and then goes down along the bottom surface of the second resin box 5, intersecting and blending with the water flow that continues to go up below, and finally passes through the flow hole on the side wall of the first resin cylinder 21 into the sleeve 51, and then flows out of the water outlet 13 of the resin chamber 11. After the water softener has been used for a period of time and the softening effect decreases, when the softening salt regeneration process is required, the trajectory of the concentrated brine in the resin chamber 11 can also be processed as shown in the above figure. Based on the rotation of the first resin box 3, the second resin box 5, and each resin cylinder 2, the water flow inside and outside can be fully "stirred", the regeneration efficiency and regeneration effect can be improved, and the concentrated brine can fully contact the resin particles, fully exchange cations, and replace the adsorbed Ca and Mg ions.

[0049] In particular, when the resin cavity 11 is in a static state for a long time, the looseness of the resin therein will decrease, especially when it runs in a static state for a certain period of time, a flow channel-type "cavity" will be formed between the inlet and outlet, and the rotation, emergency stop and other actions of the motor 4 can achieve uniform distribution of resin particles inside the resin cavity 11, which is beneficial to improving the softening efficiency.

[0050] The present invention also relates to a cleaning machine, comprising a machine body, a water supply port provided on the machine body, and a water softener as described above, wherein the outlet of the resin chamber 11 in the water softener is connected to the water supply port, and then the water softened by the water softener is fed into the water supply port of the machine body. The cleaning machine using the water softener has a better softening effect on the water, because the water in the water softener can be in more sufficient contact with the resin, thereby improving the softening efficiency of the water and correspondingly improving the cleaning ability of the cleaning machine.
