Abstract

The invention discloses an electric water heater liner cleaning method and an electric water heater. The electric water heater liner cleaning method includes steps that S1, closing a water inlet valve, and opening a sewage drain valve to discharge water in a liner through the sewage drain valve; S2, filling descaling agent in a descaling agent adding device, opening the water inlet valve, enabling the water to enter the descaling agent adding device to drive the descaling agent to enter the liner, closing the water inlet valve, wherein the water inlet quantity of water is lower than a preset capacity, and the depth of the water in the liner is smaller than a preset distance; S3, keeping the water in the liner for a preset time; S4, opening the sewage drain valve to drain all the water in the liner; S5, opening and closing the water inlet valve and sewage drain valve to wash the descaling agent in the liner for several times. The electric water heater liner cleaning method removes limescale deposited at the bottom of the liner through the descaling agent without damaging a magnesium rod in the liner, the descaling rate is higher than 90%, and the descaling effect is better.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, relates to a method for cleaning an inner tank of an electric water heater and an electric water heater. Background technique [0002] The electric water heater is a closed structure consisting of an inner tank, a heating system and an auxiliary system. In daily use, tap water contains high concentrations of metal ions such as calcium and magnesium, resulting in high hardness of tap water, and due to uneven heating and uneven heating in the inner tank of the water heater, tap water is easy to form in the inner tank. Scale, some of these scales are suspended in the inner tank water, some adhere to the inner tank wall, some fall and block the nozzle, and most of them will adhere to the heating tube. [0003] These scales attached to the heating tube will fall off irregularly. The scales that fall can be large or small. The dissolution balance is formed, and the impuritie...
