Description

Electronic constant temperature water storage electric water heater

Technical field

The utility model relates to an electronic constant temperature water storage type electric water heater, which is suitable for occasions similar to domestic hot water applications such as families, hotels, leisure shower centers and the like.

Background technique

Water storage electric water heaters have been widely used in people's lives, bringing convenience to people's lives. The structure of the existing water storage type electric water heater mainly includes: a shell, an insulation layer, a magnesium rod, an inner tank, a temperature sensor, a heating pipe, a temperature limiter, a control system, a water inlet pipe, and a water outlet pipe. When installing and using, install a mixing valve or a mechanical thermostatic mixing valve outside the body. Although the mechanical thermostatic mixing valve can ensure the constant temperature of the water outlet, the set temperature needs to be adjusted by installing a scale on the valve body. The adjustment error Large, the adjusted temperature may be very different from the user's desired temperature, and the user cannot see the temperature of the outlet water, and it must be adjusted by feeling during use. 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 hot and cold water inlet to get the desired temperature, and the constant temperature cannot be guaranteed. In order to ensure that the outlet water temperature does not gradually decrease during use It is very inconvenient to adjust the mixing valve constantly.

Contents of the invention

Aiming at the shortcomings of the existing storage-type electric water heaters, the utility model provides an electronic constant-temperature storage-type electric water heater. Valve, you only need to set the required outlet water temperature through the operation buttons of the controller, and the water heater will automatically and accurately adjust the outlet water temperature according to the set temperature, and the outlet water of the required temperature can be directly obtained from the outlet of the water heater, and the outlet The temperature can be seen intuitively on the display of the controller, which is very convenient.

The technical scheme adopted by the utility model to solve the technical problem is: there is an insulating layer between the inner tank and the outer shell, magnesium rods are installed in the inner tank, a temperature limiter is installed on the end cover of the inner tank, and the heating pipe and the temperature sensor are installed from the inner tank. The port extends into the inner tank, the water inlet pipe communicates with the water inlet of the inner tank and the cold water inlet of the electronic thermostatic valve, the water outlet of the inner tank is connected with the hot water inlet of the electronic thermostatic valve, and the outlet of the electronic thermostatic valve is connected with the water outlet pipe. A built-in temperature sensor is built in the outlet of the installed electronic thermostatic valve, and the electronic thermostatic valve is connected with the control system by a connection line and controlled by the control system. The control system has a display and buttons and is installed on the casing. When in use, the user can turn on the machine by operating the buttons and set the outlet water temperature he needs, and can see the change of the outlet water temperature on the display. The electronic thermostatic mixing valve will detect the water temperature in real time through the built-in temperature sensor, and adjust the ratio of cold and hot water in real time according to the change of the outlet temperature of the heater and the small change of the outlet water temperature of the electronic thermostatic mixing valve, so that the outlet water temperature Keep at the set temperature, so as to achieve the purpose of constant temperature.

The beneficial effects of the utility model are: the external mechanical constant temperature mixing valve is eliminated, the installation and debugging cost is greatly reduced, the constant temperature effect is rapid and accurate, the structure is simplified, the outlet water temperature can be directly seen, and the use is intuitive and convenient.

Detailed ways

In Fig. 1, there is an insulating layer (2) between the inner tank (4) and the outer shell (1), a magnesium rod (3) is installed in the inner tank (4), and a temperature limiter ( 8), the heating pipe (6) and the temperature sensor (5) extend into the inner tank (4) from the port of the inner tank (4), the water inlet pipe (9) and the inner tank water inlet (10) and the electronic thermostatic valve cold water The inlet (11) communicates, the inner tank water outlet (15) links to each other with the hot water inlet of the electronic thermostatic valve (14), and the outlet of the electronic thermostatic valve (14) links to each other with the outlet pipe (12). There is a built-in temperature sensor (13) at the outlet of the electronic thermostatic valve (14), and the electronic thermostatic valve (14) is connected with the control system (7) by a connection line. In the power-on state, the heating tube (6) heats the cold water in the inner tank (4) according to the setting, and stops working when it is heated to a certain temperature. When the user turns on the faucet to use hot water, the electronic thermostatic valve (14) will According to the small change of the outlet water temperature detected by the built-in temperature sensor (13), the ratio of cold and hot water inlets is adjusted in real time so that the outlet water temperature remains stable at the set temperature. The temperature limiter (8) is mainly to automatically cut off the power supply when the inner tank (4) temperature is too high to prevent system failure.

In Fig. 2, the control system (7) has a display (17) and a button (16) and is installed on the casing (1). The outlet water temperature can be adjusted and set as required by the button (16), and the variation of the outlet water temperature can be adjusted simultaneously. Displayed on display (17) in real time.
