Description

Technical Field

[0001] This utility model relates to a water distributor, a water softener, and a smart electrical appliance. Background Technology

[0002] A water softener is a device that removes calcium, magnesium, and other metal ions that cause high water hardness from water using ion exchange resin in a softening tank, thus softening the water. Currently, most water softeners on the market have five operating modes: softening, backwashing, slow brine flushing, forward flushing, and water replenishment. The slow brine flushing mode primarily involves drawing brine into the tank to provide sufficient sodium ions to the resin, replacing the calcium and magnesium ions adsorbed on the resin, thereby restoring the resin's ion exchange capacity and washing away the displaced calcium and magnesium ions and other impurities, ensuring the softening effect after resin regeneration. Because the brine entering the water distributor structure is vertically downwards, and in a long, conical water distributor structure, the outlets are distributed around the perimeter, the incoming brine will first impact the bottom wall of the water distributor, creating severe eddies in the internal cavity, affecting the water distribution efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a water distributor, a water softener and a smart appliance.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A lower water distributor includes a water distributor inner tank and a spiral pipe. The water distributor inner tank has a receiving cavity, and the outer circumferential surface of the water distributor inner tank has a plurality of water distribution holes communicating with the receiving cavity. The first end of the spiral pipe is spirally wound around the receiving cavity in a vertical direction, and the second end of the spiral pipe protrudes outward through the top wall of the water distributor inner tank. The wall surface of the portion of the spiral pipe located in the receiving cavity has a plurality of water outlet holes communicating with the inner cavity of the spiral pipe.

[0006] In this design, the lower water distributor has a spiral pipe that spirals vertically within the inner chamber of the distributor. When brine flows into the spiral pipe, the water flow is accelerated circumferentially within the spiral pipe. As the brine is ejected from the spiral pipe through the outlet, a rotating water flow effect is created, which facilitates the rapid flow of brine from the distribution hole. This eliminates the eddy currents formed by the brine in the vertical direction within the distributor, while also increasing the effective water outlet area of ​​the distributor, improving the water distribution effect, and making the circumferential water outlet of the distributor more uniform. This, in turn, improves the softening and regeneration rate of the resin.

[0007] Preferably, a plurality of the water outlet holes are spaced apart along the spiral direction of the spiral pipe, and each of the water outlet holes is located on the side of the spiral pipe facing the inner wall of the water distributor liner.

[0008] In this design, no outlet hole is provided on the inner side of the spiral of the spiral pipe, so the brine will not flow out from the inner side of the spiral. Instead, the water flows out from the outlet hole on the outer side of the spiral pipe, which increases the flow velocity of the water and thus improves the rotation effect of the water flow, thereby increasing the water distribution area of ​​the water distributor.

[0009] Preferably, the orientation of the water outlet is tangent to the direction of rotation of the spiral pipe.

[0010] In this solution, the above-mentioned structural configuration is adopted to increase the flow velocity of the water, thereby improving the rotation effect of the water flow and increasing the water distribution area of ​​the water distributor.

[0011] Preferably, the orientation of the water distribution hole is the same as the orientation of the water outlet hole.

[0012] In this solution, the above-mentioned structural configuration facilitates the rapid and smooth flow of rotating water generated by the spiral pipe out of the water distribution hole, reduces water resistance, increases the water distribution range of the water distributor, and improves the softening and regeneration efficiency of the resin particles.

[0013] Preferably, the lower water distributor further includes a connecting pipe, the first end of which is connected to the second end of the spiral pipe, the second end of which is used to connect to the central pipe, and the inner diameter of the connecting pipe gradually decreases from the second end of the connecting pipe to the first end of the connecting pipe.

[0014] In this design, a connecting pipe connects the central pipe to the spiral pipe. The inner diameter of the connecting pipe gradually decreases from the second end to the first end, forming a top-to-bottom contraction structure. When brine flows vertically downward from the central pipe into the connecting pipe, it first contracts and accelerates within the connecting pipe's inner cavity before entering the spiral pipe. Within the spiral pipe, the brine experiences a spiral flow, receiving further circumferential acceleration, and is then ejected from the outlet holes on the outer wall of the spiral pipe, increasing the brine's rotational velocity and thus expanding the water distribution area.

[0015] Preferably, the lower water distributor further includes a baffle plate, which is installed in the receiving cavity in an axial direction perpendicular to the inner liner of the water distributor, and the spiral pipe passes through the through hole of the baffle plate.

[0016] In this design, a baffle plate divides the inner chamber of the water distributor into layers, creating zoned brine outlets and ensuring more uniform brine distribution in each layer. Without the baffle plate, most of the brine would flow out from the lower water outlet of the inner chamber under gravity, resulting in uneven brine distribution.

[0017] Preferably, the inner wall of the water distributor's inner liner has a limiting step, and the lower surface of the periphery of the partition abuts against the limiting step.

[0018] In this solution, the lower surface of the four edges of the partition abuts against the limiting steps, which improves the fixing effect of the partition and also enhances its separation effect. The existing water distributor inner tank is made of multiple sections welded together, forming limiting steps from top to bottom between adjacent sections. The existing limiting steps can be used to fix the partition, simplifying the manufacturing process and the structural design.

[0019] Preferably, to further improve the separation effect, the four edges of the partition are sealed to the inner wall of the water distributor's inner tank.

[0020] Preferably, there are multiple partitions, and the multiple partitions are spaced apart along the height direction of the inner tank of the water distributor.

[0021] In this scheme, the above-mentioned structural configuration is adopted to form multiple layers of brine in the receiving cavity, so that the brine in each layer can flow out evenly from the water distribution holes on the periphery, thereby improving the water distribution effect.

[0022] A water softener comprising a water distributor as described above.

[0023] A smart appliance, the smart appliance comprising a water softener as described above.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows: The lower water distributor has a spiral pipe that is spirally wound in the vertical direction in the receiving cavity of the inner tank of the water distributor. When the brine flows into the spiral pipe, the water flow will be accelerated circumferentially in the spiral pipe. When it is thrown out of the spiral pipe from the water outlet, a rotating water flow effect is formed, which makes it easier for the brine to flow out of the water distribution hole quickly. This eliminates the eddy current formed by the brine in the vertical direction inside the water distributor. At the same time, it increases the effective water outlet area of ​​the water distributor, improves the water distribution effect, and makes the circumferential water outlet of the water distributor more uniform, thereby improving the softening and regeneration utilization rate of the resin.

[0040] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0041] like Figures 1-4 As shown, this embodiment discloses a lower water distributor, which includes a water distributor inner tank 1 and a spiral pipe 2. The water distributor inner tank 1 has a receiving cavity 11. The outer peripheral surface of the water distributor inner tank 1 has a plurality of water distribution holes 12 communicating with the receiving cavity 11. The first end of the spiral pipe 2 is spirally coiled around the receiving cavity 11 in a vertical direction. The second end of the spiral pipe 2 passes through the top wall of the water distributor inner tank 1 and protrudes outward. The wall surface of the portion of the spiral pipe 2 located in the receiving cavity 11 has a plurality of water outlet holes 21 communicating with the inner cavity of the spiral pipe 2. The lower water distributor has a spiral pipe 2 that is spirally wound in the vertical direction in the receiving cavity 11 of the inner tank 1. When the brine flows into the spiral pipe 2, the water flow will be accelerated circumferentially in the spiral pipe 2. When it is thrown out of the spiral pipe 2 from the water outlet 21, it will form a rotating water flow effect, which will facilitate the brine to flow out quickly from the water distribution hole 12. This will eliminate the eddy current formed by the brine in the vertical direction inside the water distributor, increase the effective water outlet area of ​​the water distributor, improve the water distribution effect, make the circumferential water outlet of the water distributor more uniform, and thus improve the softening and regeneration utilization rate of the resin.

[0042] Preferably, a plurality of water distribution holes 12 are evenly spaced along the circumferential direction of the inner liner 1 of the water distributor.

[0043] Preferably, each water distribution hole 12 is an elongated strip-shaped water distribution hole 12 extending in the vertical direction, so as to increase the water distribution area in the vertical direction.

[0044] like Figure 4 As shown, several water outlets 21 are spaced apart along the spiral direction of the spiral pipe 2, and each water outlet 21 is located on the side of the spiral pipe 2 facing the inner wall of the water distributor liner 1. No water outlets 21 are provided on the inner side of the spiral of the spiral pipe 2, so that the brine will not flow out from the inner side of the spiral, causing the water to flow out from the water outlets 21 on the outer side of the spiral pipe 2, increasing the water flow velocity, thereby improving the rotation effect of the water flow and increasing the water distribution area of ​​the water distributor.

[0045] Preferably, the lower end of the spiral pipe 2 is closed, so that the brine flows out along the outlet hole 21 on the spiral pipe 2, increasing the flow rate of the brine. Of course, the lower end of the spiral pipe 2 may not be closed, and spiral water can still be formed.

[0046] The orientation of the water outlet 21 is tangent to the spiral direction of the spiral pipe 2 to increase the water flow velocity, enhance the water flow rotation effect, and increase the water distribution area of ​​the water distributor. That is, the orientation of each water outlet 21 is tangent to the spiral pipe 2 at its location.

[0047] Preferably, the orientation of the water distribution holes 12 in the inner liner 1 of the water distributor is the same as the orientation of the water outlet holes 21, so that the rotating water flow generated by the spiral pipe 2 can flow out quickly and smoothly from the water distribution holes 12, reduce water resistance, increase the water distribution range of the water distributor, and improve the softening and regeneration efficiency of the resin particles.

[0048] like Figures 1-4 As shown, the lower water distributor also includes a connecting pipe 3. The first end of the connecting pipe 3 is connected to the second end of the spiral pipe 2, and the second end of the connecting pipe 3 is used to connect to the central pipe 5. The connecting pipe 3 is used to connect the central pipe 5 and the spiral pipe 2. The inner diameter of the connecting pipe 3 gradually decreases from the second end to the first end, forming a contraction structure from top to bottom. When the brine flows vertically downward from the central pipe 5 into the connecting pipe 3, it first contracts and accelerates through the inner cavity of the connecting pipe 3 before entering the spiral pipe 2. The brine will generate a spiral flow in the spiral pipe 2, gaining circumferential acceleration again, and then being thrown out from the outlet hole 21 on the outer wall of the spiral pipe 2, increasing the rotational flow rate of the brine and thus increasing the water distribution area.

[0049] In the existing technology, due to the backflow of water inside the inner tank of the water distributor, coupled with the large inertial effect, the brine mainly flows out from the upper outlet of the conical water distributor inner tank, while the utilization rate of the lower outlet is low. This results in a small and uneven diffusion range of the brine, which cannot cover the resin particles near the bottom of the water distributor, thus affecting the softening and regeneration of the resin particles.

[0050] In this embodiment, the lower water distributor also includes a baffle 4, which is installed in the receiving cavity 11 along an axial direction perpendicular to the inner tank 1 of the water distributor. A spiral pipe passes through the through hole of the baffle 4. The baffle 4 divides the receiving cavity 11 of the inner tank 1 of the water distributor into layers, forming zoned brine outlets, making the brine outlet of each layer more uniform. Without the baffle 4, most of the brine would flow out from the lower water outlet hole 12 of the inner tank 1 under the action of gravity, resulting in uneven water outlet.

[0051] The inner wall of the water distributor liner 1 has a limiting step 13. The lower surface of the perimeter of the partition 4 abuts against the limiting step 13, which improves the fixing effect of the partition 4 and also improves the separation effect of the partition 4. The existing water distributor liner 1 is made of multiple sections by spin welding, which forms a limiting step 13 from top to bottom between adjacent sections. The existing limiting step 13 can be used to fix the partition 4, simplifying the manufacturing process and the structural design.

[0052] Preferably, in order to further improve the separation effect, the four edges of the partition 4 are sealed to the inner wall of the water distributor inner tank 1.

[0053] Preferably, there are multiple partitions 4, which are spaced apart along the height direction of the inner tank 1 of the water distributor to form multiple layers of brine in the receiving cavity 11, so that the brine in each layer can flow out evenly from the water distribution holes 12 on the periphery, thereby improving the water distribution effect.

[0054] This embodiment also discloses a water softener, which includes a water distributor as described above.

[0055] This embodiment also discloses a smart appliance, which includes a water softener as described above.

[0056] Smart appliances include a voice control module and intelligent control components. During use, the user issues a voice control signal, and the voice control module recognizes the user's voice and controls the water softener's water production or regeneration operations through the intelligent control components, making operation simple and convenient. The intelligent control components and methods involved in these smart appliances are existing technologies and will not be elaborated upon here.
