Electric water heating device with automatic limescale removal function

Abstract

The invention provides an electric water heating device with an automatic limescale removal function. The electric water heating device comprises an electric water heating device shell, an electric water heating device liner, a filler, a heating device, a drain outlet, a water inlet, a water outlet, a TDS monitoring module, a magnetization module, an ultrasonic vibrator, an ultrasonic generator, adisplay module, a limescale removal adding device, a control module and an electromagnetic valve. By adopting an intelligent control mode, through the magnetization module, ordinary tap water is converted into magnetic water, limescale is prevented from being generated, the water quality in the electric water heating device liner is detected through the TDS monitoring module so as to judge whether limescale removal needs to be conducted on the electric water heating device liner or not, the ultrasonic vibrator and the ultrasonic generator generates ultrasonic waves to wash limescale, the limescale removal adding device delivers a liquid limescale removal agent into the electric water heating device liner through the water inlet, and through a preventing and removing combined method, the limescale is thoroughly removed.

Description

Technical field: [0001] The invention relates to the field of electric water heaters, in particular to an electric water heater for automatic descaling. Background technique: [0002] At present, electric water heaters have become a must-have appliance for households. Due to the influence of water quality, scales will appear in electric water heaters during long-term use, which makes the thermal conductivity of electric water heaters very poor, which will lead to deterioration of heat transfer on the heating surface, thus wasting fuel. Or electricity, if the scale is cemented on the electric water heater, it will also greatly increase the risk of the water heater bursting or even exploding due to thermal expansion and contraction and uneven force. This problem has been plagued by the further development of this industry. Moreover, when the water heater in the related art is descaling, it is necessary to disassemble the machine to clean the inner tank wall and parts, or to di...

[0002] At present, electric water heaters have become a must-have appliance for households. Due to the influence of water quality, scales will appear in electric water heaters during long-term use, which makes the thermal conductivity of electric water heaters very poor, which will lead to deterioration of heat transfer on the heating surface, thus wasting fuel. Or electric power, if the scale is cemented on the electric water heater, it will also greatly increase the risk of the water heater bursting or even exploding due to thermal expansion and contraction and uneven force. This problem has been plagued by the further development of this industry.

Moreover, when the water heater in the related art is descaling, it is necessary to disassemble the machine to clean the inner tank wall and parts, or to discharge sewage and dirt, which causes a lot of waste of manpower, and ordinary users do not know about electric water heaters. When to clean, the accumulated scale will increase the harmful substances in the water heater and cause a variety of skin diseases, affecting people's health
