Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to an automatic cleaning structure of a water tank of a water purifier. Background Art

[0002] For ease of use, a water purifier is usually designed with a clean water tank and a raw water tank. The clean water tank is fixed inside the water purifier, and the raw water tank can be quickly disassembled to refill with tap water, and then installed on the water purifier to provide water for the clean water tank.

[0003] Although the water entering the clean water tank is pure water filtered by the filter element, scale will still be produced after long-term use and needs to be cleaned. Since the clean water tank is fixed in the clean water tank, the difficulty of cleaning is increased. The utility model patent with application number 2023215551463 discloses a water purifier with a movable clean water tank, which can be installed in the rising box for easy wiping and cleaning, but it still cannot achieve automatic cleaning and needs to be improved. Utility Model Content

[0004] The utility model aims to provide an automatic cleaning structure for a water tank of a water purifier, which can automatically clean the water tank and improve the convenience of use.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] A water purifier automatic cleaning structure using a water tank comprises: a water purifier housing, a water tank, a cover plate, a water pump, a controller, a liquid level sensor and an ultrasonic generator, wherein the water tank is arranged in the water purifier housing, the cover plate is arranged above the water tank, a plug extending to an opening at the top of the water tank is arranged at the bottom of the cover plate, the liquid level sensor and the ultrasonic generator are respectively arranged at the bottom of the plug and point downward, lines are respectively arranged between the liquid level sensor and the ultrasonic generator and the controller, a water inlet pipe is arranged between the water outlet of the water pump and the water tank, and the controller is connected to the control end of the water pump.

[0007] Wherein, the controller adopts a single chip microcomputer.

[0008] Wherein, the controller is arranged on one side of the water purifier housing.

[0009] Wherein, a water outlet pipe is arranged at the bottom of the water purification tank, a solenoid valve is arranged on the water outlet pipe, and a drainage pipe extending to the outside of the water purifier housing is arranged at the water outlet end of the solenoid valve.

[0010] Wherein, a water nozzle pointing downward is arranged at the end of the drainage pipe.

[0011] Wherein, the controller is connected to the solenoid valve.

[0012] Wherein, the water pump is arranged in the water purifier housing.

[0013] The beneficial effects of the utility model include: an automatic cleaning structure for a water purifier using a water tank, which monitors the water level in the water tank through a liquid level sensor. When the water is purified normally, the water level in the water tank is controlled not to be higher than the bottom of the ultrasonic generator, thereby avoiding the problem of scale at the bottom of the ultrasonic generator and ensuring the durability of the ultrasonic generator. When the water tank needs to be cleaned, the water volume in the water tank is increased by a water pump, so that the liquid level in the water tank rises to submerge the bottom of the ultrasonic generator, and the ultrasonic generator is turned on for ultrasonic cleaning. The cavitation effect of ultrasonic waves in water is used to remove scale on the inner wall of the water tank, and finally the solenoid valve is opened to discharge sewage, thereby realizing automatic cleaning of the water tank and improving maintenance convenience.

[0015] Figure 2 yes Figure 1 Schematic diagram of the cleaning process after the liquid level in the clean water tank increases;

[0016] Figure 3 yes Figure 1 Schematic diagram of the structure after the cover plate is separated from the clean water tank. DETAILED DESCRIPTION

[0017] Combine the following Figure 1 to Figure 3 The technical solution of the utility model is further illustrated by specific embodiments.

[0018] like Figure 1 The water purifier water tank automatic cleaning structure shown includes: a water purifier housing 1, a water tank 6, a cover plate 3, a water pump 8, a controller 2, a liquid level sensor 14 and an ultrasonic generator 5. The water tank 6 is arranged in the water purifier housing 1 and can be fixed by screws or buckles, and the structure is stable. The cover plate 3 is arranged above the water tank 6, and a plug 4 extending to the top opening of the water tank 6 is arranged at the bottom of the cover plate 3 to protect the water tank 6 from dust.

[0019] In addition, if Figure 3 As shown, the plug 4 can be removed along with the cover 3, which is convenient for observing the inside of the clean water tank 6, verifying the cleaning effect of the inner wall of the clean water tank 6, or manually performing additional cleaning and drying, which is beneficial for the storage of the water purifier when it is not used for a long time.

[0020] The liquid level sensor 14 and the ultrasonic generator 5 are respectively arranged at the bottom of the plug 4 and point downward. A line 13 is respectively arranged between the liquid level sensor 14 and the ultrasonic generator 5 and the controller 2. The water level in the clean water tank 6 is monitored by the liquid level sensor 14. When the water is purified normally, the water level in the clean water tank 6 is controlled not to be higher than the bottom of the ultrasonic generator 5, so as to avoid the problem of scale generation at the bottom of the ultrasonic generator 5 and ensure the durability of the ultrasonic generator.

[0021] When the clean water tank 6 needs to be cleaned, the amount of water in the clean water tank 6 is increased first, so that the liquid level in the clean water tank 6 rises to the level that submerges the bottom of the ultrasonic generator 5. Figure 2 As shown, at this time, the ultrasonic generator 5 is turned on by the controller 2 to perform ultrasonic cleaning, and the scale on the inner wall of the clean water tank 6 is removed by the cavitation effect of ultrasonic waves in water.

[0022] In this embodiment, the controller 2 can be a single chip microcomputer, which has a relatively low cost. The controller 2 is arranged on one side of the water purifier housing 1, has a compact structure, and is easy to operate.

[0023] like Figure 1 As shown, a water inlet pipe 7 is provided between the water outlet of the water pump 8 and the clean water tank 6, and the controller 2 is connected to the control end of the water pump 8, so as to conveniently start the water pump 8 to replenish the clean water tank 6. In this embodiment, the water pump 8 is provided in the water purifier housing 1, and has a compact structure. A filter element and a raw water tank are usually installed in the water purifier housing 1, and the filter element is connected in series between the water inlet of the water pump 8 and the raw water tank, and tap water in the raw water tank is extracted, and purified water is obtained after filtering and sent to the clean water tank 6.

[0024] In order to facilitate the use of pure water and sewage discharge, a water outlet pipe 10 is provided at the bottom of the clean water tank 6, and a solenoid valve 9 is provided on the water outlet pipe 10. The water outlet end of the solenoid valve 9 is provided with a drain pipe 11 extending to the outside of the water purifier housing 1. Figure 2 As shown, the end of the drain pipe 11 is provided with a water nozzle 12 pointing downwards, so as to facilitate water collection and drinking.

[0025] In this embodiment, the controller 2 is connected to the electromagnetic valve 9 to facilitate automatic control. After the ultrasonic generator 5 works for several minutes, the clean water tank 6 is cleaned, and the controller 2 automatically opens the electromagnetic valve 9 to discharge sewage. By observing the turbidity of the sewage or opening the cover 3 to observe the inside of the clean water tank 6 to determine whether to clean it again, the convenience of maintenance is improved.

[0026] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
