[0039] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more specific.

[0040] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0041] According to the utility model, a water purifier with a water tank self-cleaning function is provided. Figure 1 As shown, a water tank 1 and a hot tank 2 are provided in the water purifier.

[0042] The water tank 1 is used to store purified water obtained by filtering the water purifier filter element, and has a water tank inlet 11, a water tank outlet 12 and an exhaust port 13.

[0043] The hot tank 2 has a hot tank water inlet 21 and a hot tank water outlet 22. A heating pipe 23 is provided in the hot tank 2 to heat the water in the tank body to generate steam.

[0044] A steam pipe 3 is provided between the hot tank 2 and the water tank 1 , so that the steam in the hot tank can enter the water tank 1 , thereby performing high-temperature sterilization on the inside of the water tank 1 .

[0045] According to the utility model, the water inlet 11 of the water tank is connected to the filter element of the water purifier (not shown in the figure), and the water outlet 12 of the water tank is connected to the faucet (not shown in the figure), thereby realizing the storage and supply of purified water.

[0046] In the present invention, the specific structure of the heating pipe 23 is not limited, as long as it can heat the water.

[0047] Furthermore, in the utility model, by providing a hot tank 2 with a heating tube 23, high-temperature water vapor is formed, and the steam is directed into the water tank to clean the water tank, thereby sterilizing and disinfecting, removing odors, and better solving the pollution problem in the water tank.

[0048] In a preferred embodiment, a first temperature sensor 24 is provided in the hot tank 2 for detecting the temperature of the water in the hot tank. By detecting the temperature of the water in the hot tank, the sterilization time can be controlled.

[0049] In a preferred embodiment, a second temperature sensor 14 is provided in the water tank 1 for detecting the temperature in the water tank. The sterilization effect is determined by observing the temperature in the water tank.

[0050] In a preferred embodiment, a pressure sensor 15 is provided in the water tank 1 for detecting the pressure in the water tank. When the pressure in the water tank is too high, the pressure is released through the exhaust port, thereby protecting the water tank 1 and extending the service life of the water tank 1.

[0051] Furthermore, an exhaust valve 131 is provided on the exhaust port 13 to control the opening and closing of the exhaust port 13. The structure or model of the exhaust valve 131 is not limited in the present invention, as long as the opening and closing of the exhaust port can be controlled. The exhaust valve 131 can be a solenoid valve or a one-way valve, preferably a one-way valve that can be opened under a certain pressure. When the pressure in the water tank reaches a preset value, the one-way valve automatically opens to release the pressure. When the water tank is not cleaned, external pollutants can be prevented from entering the water tank from the exhaust port.

[0052] In a preferred embodiment, the water tank 1 has an air inlet 16, and an air filter 161 is arranged on the air inlet 16, which plays a role in blocking pollutants such as bacteria and particulate matter from entering the water tank;

[0053] In the present invention, there is no limitation on the specific material of the air filter element, and those skilled in the art can freely choose it according to their needs.

[0054] In a preferred embodiment, a one-way valve 162 is provided on the air inlet 16, so that the air inlet only allows air to flow from the outside to the water tank.

[0055] In a preferred embodiment, a liquid level meter is provided in the water tank 1 and the hot tank 2 for detecting the liquid level of the water in the water tank or the hot tank.

[0056] In a preferred embodiment, a TDS sensor 17 is provided in the water tank 1 for detecting the cleanliness of the purified water in the water tank 1 .

[0057] In a preferred embodiment, the water tank outlet 12 and the hot tank outlet 22 are both connected to the faucet, and the hot tank 2 can not only clean the water tank 1, but also provide hot water for the user.

[0058] According to the utility model, when the water tank 1 needs to be cleaned, the water in the water tank is emptied through the water tank outlet, a certain amount of water is injected into the hot tank through the hot tank water inlet, and the heating tube 23 is turned on to heat the water in the hot tank to boiling, and the generated water vapor continuously enters the water tank through the steam pipe, thereby cleaning the inside of the water tank;

[0059] During the cleaning process, the pressure in the water tank is monitored. When the pressure exceeds the preset value, the exhaust valve opens for pressure relief protection.

[0060] After cleaning for a period of time, the heating tube 23 stops working, and the cleaning of the water tank 1 is completed.

[0061] In a preferred embodiment, after the heating tube 23 stops working, clean water is added to the water tank until the water tank is full, and then the water tank is emptied through the water outlet of the water tank. In this way, the cleaning residues in the water tank during steam cleaning can be mixed with the water and then discharged, further improving the cleaning effect.

[0062] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front", "rear", etc. indicate positions or positional relationships based on the working state of the present invention, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve only as an illustration.
