Self-cleaning water tank and its application in electric water heater and solar water heater

Abstract

The invention discloses a self-cleaning water tank and application of the self-cleaning water tank to an electric water heater and a solar water heater. The self-cleaning water tank comprises a water tank body, a circulation cleaning tank and an ultrasonic assembly. The water tank body is provided with a water inlet and a water outlet. The bottom of the water tank body downwards inclines to form a dirt outlet. A liquid inlet is formed in the top of the water tank body. A filter is arranged in the circulation cleaning tank so that the circulation cleaning tank can be divided into a deposition tank and a filter liquor tank. The ultrasonic assembly comprises an installing frame arranged in the water tank body, and a plurality of ultrasonic transducers arranged on the installing frame. A liquid inlet pipe communicates with the liquid inlet and the filter liquor tank, a dirt discharging pipe communicates with the dirt outlet and the deposition tank, a cleaning fluid circular flowing path is formed, and the end, stretching into the water tank body, of the liquid inlet pipe is connected with a spraying device. The self-cleaning water tank has the beneficial effects that the dismounting-free automatic cleaning function is achieved for water storage type water heater cleaning, convenience and safety are achieved, the cleaning cost is reduced, and the situation that incrustation breeds bacteria, and the body health is influenced is effectively prevented.

Description

technical field [0001] The invention relates to a self-cleaning water tank. More specifically, the present invention relates to a self-cleaning water tank and its application in electric water heaters and solar water heaters. Background technique [0002] Water heaters are essential appliances for every family. During use, solar water heaters and electric water heaters (storage water heaters) are prone to scaling. With the increase of scale, the heating effect and water outlet speed of the water heater will drop rapidly. , and scale breeds bacteria that affect health, so descaling has become one of the problems that need to be solved urgently for water heaters. [0003] At present, in the descaling of water heaters, drugs are mostly used for descaling. This method can only gradually dissolve the surface scale, the descaling effect is slow and incomplete, and it is easy to cause drug residues, which is harmful to the human body. The efficiency of the glass tube is low, the ...

[0002] Water heaters are essential appliances for every family. During use, solar water heaters and electric water heaters (storage water heaters) are prone to scaling. With the increase of scale, the heating effect and water outlet speed of the water heater will drop rapidly. , and the scale breeds bacteria that affect the health of the body, so descaling has become one of the problems that need to be solved urgently for water heaters

[0003] At present, in the descaling of water heaters, drugs are mostly used for descaling. This method can only gradually dissolve the surface scale, the descaling effect is slow and incomplete, and it is easy to cause drug residues, which is harmful to the human body. The efficiency of the glass tube is low, the cleaning and dismantling are cumbersome, and it is limited to the installation location and the cleaning labor cost is high

The patent No. is CN 103884119B, titled a solar water heater with a cleaning device, a solar water heater with a cleaning device and a drainage device is disclosed, but this solar water heater has the following problems: the water outlet located in the storage tank and the storage tank The bottom of the water tank is in a flat position, which is not conducive to the accumulation and discharge of scale. The bristles used for cleaning will have the problem of not being easy to clean and remaining scale. One end of the outlet is gathered, and the cleaning by the bristles is not thorough, the inside of the heat collecting tube and the end of the water storage tank cannot be effectively cleaned, and even the parts that the bristles can touch are relatively poor in cleaning effect
