Description

A water storage type constant temperature electric water heater

technical field

The utility model relates to an electric water heater, in particular to a water storage type constant temperature electric water heater.

Background technique

Water storage electric water heaters have been widely used in people's lives, bringing convenience to people's lives. When the existing water storage type electric water heater is installed and used, a mixing valve or a mechanical thermostatic mixing valve is installed outside the body to adjust the outlet water temperature. Although the mechanical thermostatic mixing valve can ensure the constant temperature of the outlet water, the accuracy is not high. The set temperature needs to be adjusted by the scale installed on the valve body, the adjustment error is large, the adjusted temperature may be very different from the user's desired temperature, and the user cannot see the outlet water temperature, and it is still in use. Adjust by feeling. Moreover, mechanical thermostatic mixing valves are generally larger in shape, more complicated to install, occupy a lot of space, and are not low in cost. If an ordinary water mixing valve is installed, the effect will be even worse. The user needs to adjust the ratio of cold and hot water to get the desired temperature, and the constant temperature cannot be guaranteed. The temperature of the hot water in the inner tank will drop during use. , in order to ensure that the temperature of the outlet water does not gradually decrease, it is very inconvenient to constantly adjust the mixing valve to maintain the temperature.
