[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 An automatic descaling water dispenser includes a housing 1. A descaling agent tank 2 is fixed to the top outer wall of the housing 1 by bolts. Two feed pipes are welded to one end of the descaling agent tank 2. A sealing cap is threaded to one end of each feed pipe. Opening the sealing cap allows the descaling agent to be put into the descaling agent tank 2.

[0025] The descaling agent tank 2 contains two sets of water boiler components 3. Each water boiler component 3 consists of a heat preservation component 301 and a water heating component 302. The water heating component 302 includes a water tank. A liquid passage pipe 304 is sealed and inserted into the top of the water tank. One end of the liquid passage pipe 304 is snapped with a second solenoid valve 305. The other end of the second solenoid valve 305 is sealed and inserted with an inlet pipe 306. The top end of the inlet pipe 306 is sealed and inserted into the bottom of the descaling agent tank 2. A water inlet pipe 305 is sealed and inserted into the top of the water tank. 7. The descaling agent in the descaling agent tank 2 flows into the water tank through the liquid inlet pipe 304 and the water inlet pipe 307 for soaking. The other end of the water inlet pipe 307 is connected to the third solenoid valve 308. The other end of the third solenoid valve 308 is sealed and inserted into the second three-way pipe 6. One end of the second three-way pipe 6 is sealed and inserted into the connecting pipe 5. The other end of the connecting pipe 5 passes through the housing 1. The water flows into the water tank through the connecting pipe 5, the second three-way pipe 6, the third solenoid valve 308, and the water inlet pipe 307.

[0026] The heat preservation component 301 includes a heat preservation box 3011. Both the water tank and the top of the heat preservation box 3011 are sealed with exhaust pipes. Water vapor in the water tank and the heat preservation box 3011 is discharged from the exhaust pipes. Heating tubes 311 are inserted into one side of both the water tank and the heat preservation box 3011. The two heating tubes 311 are located in the water tank and the heat preservation box 3011 respectively, thereby heating the water in the water tank and the heat preservation box 3011. A first solenoid valve 303 is sealed between the heat preservation box 3011 and the water tank. When the first solenoid valve 303 is opened, the boiling water in the water tank is input into the heat preservation box 3011 for heat preservation through the first solenoid valve 303.

[0027] The water outlet of the insulated box 3011 is connected to a first tee pipe 309 via a flange. One end of the first tee pipe 309 is threaded to a water tap 310. The water tap 310 is located on the outside of the shell 1. A placement plate 16 is fixed to one side of the outer wall of the shell 1 by bolts. The placement plate 16 is located below the water tap 310. Place the water cup on the placement plate 16, and then turn on the water tap 310. The boiling water in the insulated box 3011 flows into the water cup through the first tee pipe 309 and the water tap 310.

[0028] Temperature sensors 4 are inserted into one side of both the water tank and the insulation box 3011. The temperature sensors 4, model PT100, are located inside the water tank and insulation box 3011, respectively, to detect the temperature inside the water tank and insulation box 3011. A support base 7 is bolted between the insulation box 3011 and the water tank. An insulation layer 3012, made of polyurethane foam, is provided on the outer wall of the insulation box 3011 for better insulation. A fourth solenoid valve 8 is sealed and inserted into one end of the first three-way pipe 309. A drain pipe 9 is sealed and inserted into the bottom end of the fourth solenoid valve 8. Wastewater is discharged from the first three-way pipe 309, the fourth solenoid valve 8, and the drain pipe 9, thus achieving automatic descaling. Two support frames 10 are bolted to the inner bottom wall of the shell 1. The top of the housing 0 is fixedly connected to the bottom of the insulation box 3011. A liquid level sensor 17 is fixed to one inner wall of the insulation box 3011 and one inner wall of the water tank by bolts. The liquid level sensor 17 is a DSC-2.5, which detects the liquid level in the water tank and the insulation box 3011. A mounting plate 11 is fixed to one outer wall of the housing 1 by bolts. A plurality of control buttons 13 and a display screen 14 are provided on one side of the mounting plate 11. A controller 12 is fixed to one side of the mounting plate 11 by bolts. The controller 12 is a DATA-7311. The controller 12 is electrically connected to the first solenoid valve 303, the second solenoid valve 305, the third solenoid valve 308, the temperature sensor 4, the fourth solenoid valve 8, and the liquid level sensor 17. A side door 15 is provided on one side of the housing 1.

[0029] The working principle of this embodiment is as follows: When in use, first, connect the connecting pipe 5 to the external water source, then power on the water dispenser and start the water dispenser. Then, the controller 12 controls the third solenoid valve 308 to open, and the water flows through the connecting pipe 5, the second three-way pipe 6, the third solenoid valve 308, and the water inlet pipe 307 into the water tank. The liquid level sensor 17 in the water tank is used to detect the liquid level. When the liquid level sensor 17 in the water tank detects that the liquid level has reached the set value, it transmits the information to the controller 12 for processing. Then, the controller 12 controls the heating tube 311 in the water tank to heat the water in the water tank, and uses the temperature sensor 4 in the water tank to detect the water temperature in the water tank.

[0030] When the water temperature in the tank reaches the boiling water temperature, the controller 12 controls the first solenoid valve 303 to open. Then, the boiling water in the tank is input into the heat preservation box 3011 through the first solenoid valve 303 for heat preservation. During the heat preservation process, the water temperature in the heat preservation box 3011 is detected by the temperature sensor 4 in the heat preservation box 3011. When the water temperature is detected to drop, the controller 12 controls the heating tube 311 in the heat preservation box 3011 to heat the water, thereby maintaining the water temperature in the heat preservation box 3011.

[0031] When drinking water, first, place the water cup on the placement plate 16, and then turn on the hot water tap 310. The hot water in the insulated box 3011 flows into the water cup through the first three-way pipe 309 and the hot water tap 310.

[0032] During descaling, the controller 12 controls the second solenoid valve 305 and the third solenoid valve 308 to open. Water and descaling agent in the descaling agent tank 2 flow into the water tank through the liquid inlet pipe 304 and the water inlet pipe 307 for soaking. After soaking for a period of time, the fourth solenoid valve 8 opens, and sewage is discharged from the first three-way pipe 309, the fourth solenoid valve 8 and the drain pipe 9, thereby achieving automatic descaling.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
