Problems solved by technology
When not in use, because the water mixing valve is one-way to close the water outlet, so that it is in a closed state, so its inner tank is in a closed state of high temperature and high pressure for a long time, which brings extreme pressure to the closed electric water heater. The biggest disadvantage: short life, poor safety, and great hidden dangers; because the inner tank is in a closed state of high temperature and high pressure for a long time, the metal inner tank and electric heating elements are easily corroded under high temperature and high pressure, thus shortening its life. Once the pressure reducing valve fails, an explosion will occur, causing danger.
Therefore, people always feel that electric water heaters are not safe, and hope to solve the problems existing in existing products
And because it needs to bear pressure, the inner tank must be a cylindrical spherical structure, and the shape of the product is also single.

Embodiment approach
[0020] The first embodiment of the open type electric water heater of the present invention is as follows: figure 1 As shown, the water tank is installed with a water inlet valve 11 for the first time, and the water inlet valve is connected with the running water pipe 12 for the first time. The first water inlet valve is used separately from the double switch mixing valve. The first water inlet valve is only opened when the water tank is fed for the first time, and it is always closed when it is used normally. When filling water for the first time, open the water inlet valve for the first time and close the double switch mixing valve. At this time, water starts to enter the water tank. When water comes out from the drip port, it proves that the water tank has been filled with water. At this time, close the water inlet for the first time. Valve, when in normal use in the future, this water inlet valve must be in closed state all the time for the first time. When the electric h...

The invention discloses an open type electric water heater which comprises a water tank, an electric heating tube, a water outlet tube, a water inlet tube, a sprinkler and a water mixing valve; the electric heating tube and the water outlet tube are positioned inside the water tank; and the water outlet tube, the water inlet tube, the sprinkler and the water mixing valve are communicated. The open type electric water heater is characterized in that the inside of the water tank is provided with a water dripping gap tube; and a nozzle on the top part of the water dripping gap tube is positioned above the highest liquid level of the water tank and keeps communication with atmosphere all along. The water mixing valve is a double-linked switch water mixing valve. The open type electric water heater has the advantages of simple structure, high safety and long service life.
Description
technical field [0001] The invention relates to an electric water heater, in particular to an open electric water heater. Background technique [0002] The electric water heaters used in existing families or hotel rooms are mainly closed electric water heaters. The closed electric water heaters are mainly composed of inner tanks, temperature control elements, pressure relief valves, electric heating elements extending into the inner tanks, and inlets connected to the inner tanks. The water pipe and the water outlet pipe, the inner tank is a closed body that only communicates with the water inlet and outlet pipes. Connect with water pipe. When in use, the water mixing valve is opened, and the hot water in the inner tank is discharged through the corresponding water mixing valve under the action of the water pressure in the tap water pipe. When not in use, because the water mixing valve is one-way to close the water outlet, so that it is in a closed state, so its inner tank ...
