Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, in particular to a water dispenser capable of automatically cleaning scale from a hot tank. Background Art

[0002] The cold / hot water dispensers on the market basically use hot water tanks to heat water to provide hot water. However, as the use time is too long, white scale will form inside the hot tank. The scale affects the heat transfer, prolongs the heating time, and wastes electricity. In addition, scale is generally harmful to the human body. Some trace elements such as iron, manganese, and magnesium will be produced in the scale. Once excessive intake, it may endanger normal health and even cause poisoning. In addition, a certain amount of precipitation will be produced in the scale. After entering the body, it will induce some diseases such as gallstones and kidney stones.

[0003] Chinese patent publication number CN213524829U discloses a water dispenser with an easily disassembled water tank, which adopts a detachable heating tank, and can clean the scale inside the heating tank, thereby improving the water quality. However, the above technology requires the heating tank to be completely removed before the scale can be manually cleaned. The disassembly process causes unnecessary trouble and is not suitable for frequent cleaning. Therefore, the utility model provides a water dispenser that can automatically clean the scale in the hot tank to solve the above problem. Utility Model Content

All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0019] See Figures 1 to 3 As shown, a water dispenser capable of automatically cleaning hot tank scale comprises a machine body 1, a water outlet 11 is fixedly embedded on the top wall of the water receiving tank of the machine body 1, a water filter component 2, a hot water treatment component 3 and a cold water treatment component 4 are built in the machine body 1, the water inlet ends of the hot water treatment component 3 and the cold water treatment component 4 are both connected to the water filter component 2, the water outlet ends of the hot water treatment component 3 and the cold water treatment component 4 are both connected to the water outlet 11, the hot water treatment component 3 comprises a hot tank water inlet valve 31, an instant heater 32, a hot tank body 33 and a hot tank water outlet valve 34 which are connected in sequence, and a gas-liquid separator 35 is fixedly embedded on the top of the hot tank body 33;

[0020] Specifically, the heater 32 is used to heat drinking water, the hot tank water outlet valve 34 is used to control the drainage of the hot tank body 33, and the gas-liquid separator 35 is used to discharge the gas in the hot tank body 33. It is worth noting that the gas-liquid separator 35 can be a venturi tube structure. The venturi tube is a pipe that uses the capillary phenomenon of the liquid to transport the liquid to a higher place. It consists of a capillary tube and a larger container. The liquid rises to the top of the container through the capillary tube. This is because the liquid interacts with the inner wall of the capillary tube to form surface tension, which adsorbs the liquid on the capillary tube wall, thereby causing the liquid level to rise.

[0021] Furthermore, the cold water treatment assembly 4 includes a cold tank water inlet valve 41, a cold tank body 42, a cold tank water outlet valve 43 and a flow-through UV sterilizer 44 which are connected in sequence, and the output end of the flow-through UV sterilizer 44 and the output end of the hot tank water outlet valve 34 are both connected to the water outlet nozzle 11;

[0022] Specifically, the cold tank water outlet valve 43 is used to control the water discharge from the cold tank body 42, and the over-flow UV sterilizer 44 plays a role in sterilization and disinfection, thereby improving the water quality safety of the cold drinking water.

[0023] Furthermore, the water filter assembly 2 includes a water inlet joint 21, a pressure reducing valve 22, a filter cartridge tank 23, a water inlet main valve 24 and a flow meter 25 which are connected in sequence.

[0026] Specifically, the carbon fiber filter element is used for daily tap water filtration to ensure the quality of drinking water. After unscrewing the tank cover 231, the carbon fiber filter element can be pulled out, and the replacement and cleaning filter element can be put into the filter element tank 23. The sealing ring 232 is clamped on the outside of the open end of the filter element tank 23. After reinstalling the tank cover 231, the sealing ring 232 is fully squeezed to ensure the sealing effect. It is worth mentioning that the cleaning sheet contains citric acid component (CH3COOH), and the scale component is calcium carbonate (CaCO3). The two react to generate carbon dioxide and calcium acetate (soluble in water). The reaction chemical formula is: CaCO3+2CH3COOH=CO2+Ca(CH3COO)+2H2O.

[0027] Furthermore, a drain valve 5 is fixedly embedded at the bottom of the hot tank body 33 and the cold tank body 42;

[0028] Specifically, opening the drain valve 5 can drain the drinking water in the hot tank body 33 and the cold tank body 42 .

[0029] Furthermore, the body 1 has a built-in PCB board 6 for controlling the operation of the water dispenser, and a display screen 61 and a plurality of control buttons 62 are installed on the PCB board 6, and the display screen 61 and the control buttons 62 are both inserted out of the body 1;

[0030] Specifically, the PCB board 6 is used to control the operation of the above electronic components, the display screen 61 is used to display the operating status of the water dispenser, and the control button 62 is used to input control commands. The specific operation steps are as follows:

[0032] Step 2: Select the hot tank cleaning item in the setting function of the display screen 61; after the user removes the carbon fiber filter element, insert the cleaning filter element (300ml of warm water + cleaning sheet, in which the cleaning sheet contains citric acid), and then touch the confirmation key to enter the hot tank cleaning function state;

[0033] Step 3: Open the water inlet main valve 24 and the hot tank water inlet valve 31, and close the hot tank water outlet valve 34 (tentatively set for 10S) to fill the air chamber at the top of the hot tank with 80-150mL of water;

[0034] Step 4: Remind the user to take 150ml of hot water;

[0035] Step 5: Remind the user to take 150 ml of cold water;

[0036] Step 6: Let the machine stand for 10 minutes to allow the cleaning solution to fully soak the cold tank / hot tank;

[0037] Step 7: Remind the user to flush with 3000ml of hot water;

[0038] Step 8: Remind the user to rinse with 3000ml of cold water;

[0039] Step 9: The user uses a litmus test to test the water after cleaning. If it fails, the user presses the control button 62 to repeat steps 3 to 8. If it passes, the function of the cleaning machine is completed, and the power-on time of the machine is re-accumulated.

[0040] Step 10: If you touch the exit button in the cleaning state, you can passively exit the cleaning machine function state, and at the same time re-accumulate the power-on time of the machine.
