Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to an automatic descaling device for water dispenser tanks. Background Technology

[0002] A water heater is an electrical appliance used to heat cold water to a boil, widely used in homes, schools, offices, and public places. It heats water to 100°C using a built-in heating element (such as a heating tube or heating rod) and is equipped with a heat preservation function to maintain the water temperature. Modern water heaters typically feature automatic heating, water temperature display, and anti-dry-burn protection, making them safe and convenient to use. They come in various designs, including freestanding, countertop, and wall-mounted models, to meet the needs of different locations.

[0003] However, water heaters are prone to limescale buildup during use, making regular cleaning essential. However, most common descaling methods on the market are manual, and traditional descaling methods often involve regular manual cleaning, which is labor-intensive and inefficient.

[0004] Therefore, an automatic descaling device for water heater tanks is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic descaling device for water heater tanks.

The detection chamber has a sensor mounting hole communicating with its interior. A residual agent sensor is installed in the sensor mounting hole. The bottom of the drain chamber is connected to a lower drain hole. The detection chamber and the drain chamber are jointly provided with a switching component. When the liquid inlet volume is greater than the liquid outlet volume of the detection chamber, the switching component controls the detection chamber and the drain chamber to separate; otherwise, they are connected.

[0023] An automatic descaling device for water heater tanks, such as Figure 1 As shown, the system includes a water tank 8, a sprayer 7 installed at the top of the water tank 8, a mixing pipe connected to the sprayer 7 and passing through the top of the water tank 8, a venturi tube 2 connected to the mixing pipe, an acid / alkali solution pipe connected to one end inlet of the venturi tube 2, and an inlet pipe connected to the other end inlet of the venturi tube 2 for introducing pure water. The acid / alkali solution pipe is connected to an acid tank 3 and an alkali tank 4 installed inside the system. The acid tank 3 is connected to the acid / alkali solution pipe through an acid solenoid valve 5, and the alkali tank 4 is connected to the acid / alkali solution pipe through an alkali solenoid valve 6. A heating pipe 9 is installed inside the water tank 8 and passes through the outer wall of the water tank 8. A booster pump 1 is connected to the inlet pipe.

[0024] In actual operation, this invention first introduces acid through the acid-alkali pipeline, which sprays the acid into the water tank 8 via the sprayer 7 to remove scale. Then, a booster pump 1 introduces purified water through the inlet pipeline into the sprayer 7 to clean the water tank 8 and remove any remaining liquid. When the pH value in the water tank 8 is determined to be the same as the initial value, the booster pump 1 is turned off. Alkali is then introduced through the acid-alkali pipeline, which sprays the alkali into the water tank 8 via the sprayer 7 to further remove scale. After the alkali is stopped, purified water is introduced again through the booster pump 1 to complete the cleaning of the inside of the water tank 8. This process removes scale without the need for manual cleaning.

[0025] like Figure 2 and Figure 3As shown, a sampler 10 is connected to the bottom of the water tank 8. The sampler 10 can sample the water in the water tank 8. The sampler 10 includes a detection chamber 11, a drain chamber 17 detachably connected to and communicating with the bottom of the detection chamber 11, and an upper cover 14 detachably connected to the top of the detection chamber 11. An inlet hole 15 communicating with the bottom of the water tank 8 is fixedly connected to the upper cover 14. A liquid distribution umbrella 16 is fixedly connected to the inner top surface of the upper cover 14. A sensor mounting hole 13 communicating with the interior of the detection chamber 11 is opened on the detection chamber 11. An upper drain hole 12 is connected to the side wall of the detection chamber 11. A residual agent sensor is installed inside the mounting hole 13. The bottom of the discharge chamber 17 is connected to a lower discharge hole 18. The detection chamber 11 and the discharge chamber 17 are both equipped with a switching component. When the liquid inlet 15 is greater than the liquid outlet 11, the switching component controls the detection chamber 11 to separate from the discharge chamber 17. Otherwise, the two are connected. The switching component includes an upward float 19 located in the detection chamber 11, a blocking ball 20 located in the discharge chamber 17, and a connecting rod 21 fixedly connected between the two. A limiting frame 22 for supporting the blocking ball 20 is fixedly connected to the inner bottom surface of the discharge chamber 17.

[0026] When the sampler 10 is working, if the liquid inlet 15 is greater than the liquid outlet 11, the amount of liquid in the detection chamber 11 will gradually increase. At this time, the upward-pulling float 19, due to the buoyancy of the liquid, begins to pull the sealing ball 20 through the connecting rod 21 to seal the bottom of the detection chamber 11, thus separating the detection chamber 11 from the drain chamber 17. At this time, the detection chamber 11 and the drain chamber 17 are temporarily disconnected, but the sealing ball 20 cannot achieve a complete seal. However, the residue sensor can still detect the liquid in it to determine whether there is still any residue. The excess liquid can flow out through the upper drain hole 12. However, since the sealing ball 20 cannot completely seal the liquid, the amount of liquid in the detection chamber 11 will decrease as the liquid flowing out of the detection chamber 11 is greater than the liquid entering. Therefore, the upper float 19 will fall, and the sealing ball 20 will open the connection between the detection chamber 11 and the drain chamber 17. The sealing ball 20 will then rest on the limit frame 22, allowing a large amount of liquid in the detection chamber 11 to be discharged. In this way, the sample holder 10 can also be rinsed with pure water to prepare it for the next use.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
