[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

Embodiment Construction
[0031] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] First, please refer to figure 1 , an electric water heater with a flow control function, the electric water heater includes a water heater liner 13 and an outer shell 26, the lower part of the water heater is provided with a cold water inlet pipe 6, and one side of the upper part is provided with a hot water outlet pipe 7, and the cold water passes through the cold water inlet pipe 6 Enter the water heater liner 13, then heat in the water heater liner 13, then flow out through the hot water outlet pipe 7.
[0033] figure 2 A schematic diagram of the inner tank 13 of the water heater is shown. The inner tank 13 of the water heater is divided into four layers, and every adjacent two layers are closely bonded. From the inside to the outside, there are respectively an inner coating layer 22, an aluminum alloy layer 23, a stainless st...

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...
