[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4 An embodiment of this utility model provides a commercial water dispenser with a scale-cleaning mechanism, comprising a water tank 1 and a water storage tank 8. A fixing plate 9 is fixedly connected to the outer wall of the water tank 1, and a motor 10 is fixedly connected to the top of the fixing plate 9. A disc 16 is fixedly connected to the output end of the motor 10. A support plate 3 is fixedly connected to the outer wall of the water tank 1. The disc 16 is rotatably connected to the inner wall of the support plate 3. Two limiting blocks 13 are fixedly connected to the outer wall of the support plate 3. A sliding rod 12 is slidably connected to the inner wall of the limiting block 13. A sliding groove 15 is fixedly connected to the connection point of the sliding rod 12 near the disc 16. A slider 14 is fixedly connected to the outer wall of the disc 16. The slider 14 is slidably connected to the inner wall of the sliding groove 15.

[0032] When the scale cleaning mechanism needs to be activated, the cleaning program is first set through the control panel 5. Then, the motor 10 on the top of the fixed plate 9 is powered on and runs. The output end of the motor 10 drives the disc 16 to rotate on the inner wall of the support plate 3. The slider 14 on the outer wall of the disc 16 rotates synchronously. Since the slider 14 is slidably connected to the inner wall of the groove 15 of the slide rod 12, and the slide rod 12 is restricted by the limit blocks 13 on both sides to slide horizontally, when the slider 14 rotates, it will push the slide rod 12 to make reciprocating linear motion through the groove 15. This process converts the circular motion of the motor 10 into the horizontal reciprocating motion of the slide rod 12, providing power for the movement of the subsequent cleaning components and ensuring that the cleaning range can cover the relevant components at the output end of the water storage tank 8.

[0033] Reference Figures 3-5 A fixed ring 11 is fixedly connected to the end of the slide bar 12 away from the limit block 13. A delivery pipe 26 is fixedly connected to the output end of the water storage tank 8. The delivery pipe 26 is fixedly connected to the inner wall of the fixed ring 11. A nozzle 18 is fixedly connected to the inner wall of the end of the delivery pipe 26 away from the water storage tank 8.

[0034] When the slide bar 12 reciprocates, the fixed ring 11 at the end away from the limit block 13 will move synchronously. Since the delivery pipe 26 is fixed to the inner wall of the fixed ring 11, the delivery pipe 26 will reciprocate along with the fixed ring 11. The water storage tank 8 is pre-stored with a cleaning solution made of water, baking soda and white vinegar. During cleaning, the water storage tank 8 delivers the cleaning solution to the delivery pipe 26 through the output end. The cleaning solution is finally sprayed out through the nozzle 18 at the end of the delivery pipe 26. With the reciprocating movement of the delivery pipe 26, the nozzle 18 can evenly spray the cleaning solution on the target area to achieve a thorough cleaning of the scale.

[0035] Reference Figures 6-7 The inner walls of the water tank 1 are fixedly connected to both sides of a first lock shell 19 and a second lock shell 20. The second lock shell 20 is fixedly connected to the top of the first lock shell 19. The inner wall of the first lock shell 19 is slidably connected to a first pin 21. The outer wall of the first pin 21 is fitted with a first spring 23. The inner wall of the second lock shell 20 is slidably connected to a second pin 22. The outer wall of the second pin 22 is fitted with a second spring 24. The outer wall of the first pin 21 is fixedly connected to a protrusion 25. The right end of the first pin 21 is fixedly connected to a locking block 27. The bottom of the second pin 22 is fixedly connected to a locking block 17, which engages between the protrusion 25 and the locking block 27.

[0036] The filter plate 7 on the inner wall of the water tank 1 is used to filter impurities in the water. It needs to be disassembled and cleaned after long-term use. Its fixation depends on the cooperation structure between the first locking shell 19 and the second locking shell 20. When installing the filter plate 7, push the filter plate 7 into the corresponding position on the inner wall of the water tank 1. The filter plate 7 will push the first pin 21 to slide in the first locking shell 19. The first spring 23 on the outer wall of the first pin 21 is compressed. At the same time, the protrusion 25 on the first pin 21 will also move, releasing the restriction on the second pin 22 in the second locking shell 20. The second spring 24 returns to its original position and pushes the second pin 22 down, so that the locking block 17 at the bottom of the second pin 22 engages between the protrusion 25 and the locking block 27, locking the position of the first pin 21 and locking the locking block 27 with the filter plate 7. When disassembling, pull the second pin 22 upward to release the lock.

[0037] Reference Figure 6 A filter plate 7 is movably connected to the inner wall of water tank 1, and a locking block 27 engages with the filter plate 7.

[0038] The filter plate 7 is in a movable connection state on the inner wall of the water tank 1. Its stable installation depends on the locking action of the locking block 27. When the first pin 21 in the first lock housing 19 is in the structural locking state, the locking block 27 at the right end of the first pin 21 will be tightly locked in the corresponding slot of the filter plate 7, restricting the lateral and longitudinal movement of the filter plate 7. This locking structure can ensure that the filter plate 7 will not shift even if it is impacted by water flow during the operation of the water tank 1, and will always remain in the filtration position, stably playing the role of filtering impurities in the water, and preventing impurities from entering the subsequent water circuit and causing blockage or accelerated scale formation.

[0039] Reference Figure 2 An electrical plug 6 is fixedly connected to the outer rear wall of water tank 1, and a drain pipe 2 is fixedly connected to the outer rear wall of water tank 1.

[0040] The electrical plug 6 on the outer wall of the rear side of water tank 1 is the power supply interface for the entire commercial water dispenser. When in use, the electrical plug 6 is connected to an external power source to provide power to the heating components, motor 10, control panel 5 and other electrical components inside water tank 1, ensuring the normal operation of the water dispenser. The drain pipe 2 on the rear side of water tank 1 is used to drain wastewater. When the water dispenser needs to be changed and scale removed, and residual cleaning solution is drained, or when there is too much water in water tank 1, the valve of drain pipe 2 is opened, and the water or wastewater in water tank 1 will be smoothly drained through drain pipe 2, maintaining the cleanliness and normal water level inside water tank 1.

[0041] Reference Figure 1 A control panel 5 is fixedly connected to the front outer wall of water tank 1, and a faucet 4 is fixedly connected to the lower part of the front outer wall of water tank 1 near the control panel 5.

[0042] The control panel 5 on the front of the water tank 1 is the core of the water heater's operation control. Users can set the water temperature, start heating, and start the scale cleaning program through the control panel 5. The control panel 5 will send signals to the corresponding motor 10, heating components, and other components according to the instructions to control their operating status. When the water heater has finished heating and reached the set water temperature, the user can open the faucet 4 below. The hot water in the water tank 1 will be transported to the faucet 4 through the internal water circuit and flow out from the faucet 4 for use, realizing the convenient access to hot water.

[0043] Reference Figure 3 The internal components of the water storage tank 8 are composed of water, baking soda, and white vinegar dissolved together.

[0044] The water tank 8 is a component for storing and supplying cleaning solution. The cleaning solution stored inside is made by dissolving water, baking soda, and white vinegar in a certain proportion. Baking soda is weakly alkaline, and white vinegar contains acetic acid. The mixture formed after the two are dissolved has both alkaline softening and acidic dissolving effects on limescale, and can effectively decompose components such as calcium carbonate and magnesium hydroxide in limescale. When the cleaning program is started, the water tank 8 will stably deliver the internal cleaning solution to the delivery pipe 26 as needed, providing a continuous source of cleaning solution for the nozzle 18, ensuring that the limescale cleaning work is carried out effectively.

[0045] Working principle: After the power is turned on, the power cord 6 supplies power to each component. The control panel 5 can set the operation instructions. When cleaning limescale, the mixture of water, baking soda and white vinegar in the water tank 8 is delivered to the nozzle 18 through the delivery pipe 26. At the same time, the motor 10 drives the disc 16 to rotate. Through the cooperation of the slider 14 and the slide groove 15, the circular motion is converted into the reciprocating motion of the slide rod 12, so that the fixed ring 11 drives the delivery pipe 26 and the nozzle 18 to move, and the cleaning liquid is sprayed evenly to dissolve the limescale. The wastewater is discharged through the drain pipe 2.

[0046] The filter plate 7 inside the water tank 1 is fixed by a locking structure. The first pin 21 uses the elastic potential energy of the first spring 23 to generate force with the first lock shell 19. After being pushed by the filter plate 7, the locking block 17 of the second pin 22 is locked between the protrusion 25 and the locking block 27 to ensure that the filter plate 7 can stably filter impurities. When disassembling, pulling the second pin 22 can unlock it, making it easy to replace and clean the filter plate 7. The heated water is supplied through the faucet 4. The whole system realizes the functions of hot water supply and automatic scale cleaning through the linkage of various components.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
