Abstract

The invention provides a method for cleaning incrustation in a water heater inner container. The method for cleaning the incrustation in the water heater inner container comprises the following stepsof adding a water heater inner container cleaning agent into the water heater inner container which is filled with water; then heating the water in the water heater inner container to 60-80 DEG C andmaking the water heater inner container cleaning agent stand for 1-3h; and discharging mixed liquor. The method for cleaning the incrustation in the water heater inner container is easy to operate andcapable of realizing the cleaning of the incrustation in the water heater inner container without the need for dismounting the inner container.

Description

technical field [0001] The invention relates to the field of household water heaters, in particular to a method for cleaning scales in the inner tank of the water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. The function of the inner tank of the water heater is to store water, and it must have the characteristics of heat preservation, pressure resistance, no rust, no scale, and no water seepage. [0003] After long-term use, the inner tank of the water heater will accumulate a certain amount of scale, especially in areas with hard water quality, a large amount of rust will accumulate in the inner tank of the water heater...
