Electric water heater capable of automatically controlling temperature

Abstract

The invention provides an electric water heater capable of automatically controlling temperature. The electric water heater comprises a water heater inner container. The inner container comprises multilayer structures. The electric water heater and the water heater inner container comprise four side walls and a bottom wall, and the bottom and each side wall are respectively provided with four electric heaters. With heating temperature rising, the electric heaters are started and heat unceasingly successively, and the temperature of water is controlled according to flow of the water at the same time. The electric water heater can control heating power according to the water temperature, the inner container is prevented from being heated and expanding, the temperature of the water is controlled according to the flow of the water at the same time, and uniformity of the heating temperature is guaranteed.

Description

technical field [0001] The invention belongs to the field of water heaters, in particular to an electric water heater with automatic temperature control. Background technique [0002] The heating power of the electric water heater commonly used in the family is relatively single at present, generally only has one kind of heating power, and the heating power will not change as the temperature of the water increases. Therefore, in this case, for a water heater with a relatively large heating power, once the heating is started, the temperature of the water will increase rapidly. It leads to rapid expansion of the inner tank, and multiple rapid expansions will easily lead to loosening of the combination between the inner tank and other shell materials, and will also reduce the frequency of use of the inner tank; some water heaters have low heating power, although they will heat up the water The speed is slow, thereby reducing the rapid thermal expansion of the inner tank, but t...

AI Technical Summary

Problems solved by technology

[0002] At present, the heating power of electric water heaters commonly used in households is relatively single. Generally, there is only one heating power, and the heating power will not change with the increase of water temperature.

Therefore, in this case, for a water heater with a relatively large heating power, once the heating is started, the temperature of the water will increase rapidly. It leads to rapid expansion of the inner tank, and multiple rapid expansions will easily lead to loosening of the combination between the inner tank and other shell materials, and will also reduce the frequency of use of the inner tank; some water heaters have low heating power, although they will heat up the water The speed is slow, thereby reducing the rapid thermal expansion of the inner tank, but the heating speed of the overall water is slow, thus affecting the timeliness of use
