Electric water heater with flow control function

Abstract

The invention provides an electric water heater with a flow control function. The electric water heater comprises a water heater linear, an electric water heater body, a flow controller, a flow sensor and a central control unit. The flow velocity of the flow controller is controlled by the central control unit according to measured water level and flow. In order to ensure that the temperature of water inside the linear reaches a predetermined temperature, the flow velocity of the flow controller can be controlled by the central controller according to water temperature and flow. The electric water heater with the flow control function can achieve control over flow velocity of water entering the water heater through the flow controller and the flow sensor.

Description

technical field [0001] The invention belongs to the field of water heaters, in particular to an electric water heater with a flow control function. 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 the ove...

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
