The electric water heater adopts electric energy as a main energy material, and high-temperature heat generated after electrification directly heats water stored in the electric water heater so as to achieve the purpose of preparing hot water.

The electric water heater generally includes a water tank, an electric heating component, an electric control board and other components, wherein a water storage cavity is formed in the water tank to store water to be heated, the electric heating component is inserted into the water storage cavity formed in the water tank, and the electric control board is used for controlling the electric heating component to be powered on and powered off to operate, so that the water in the water tank is heated to a set temperature.

For a water tank of an electric water heater, the water tank generally comprises an outer shell and an inner container, and an insulating layer is formed between the outer shell and the inner container. Wherein, the shell is generally made of plastic materials to meet the design requirements of beautiful and diversified shapes; the inner container can be a metal container body or a plastic container body according to requirements.

In addition, the heat preservation layer formed between shell and the inner bag, commonly used heat preservation material have: asbestos, sponge, foam plastic, polyurethane foam and the like, and in order to obtain a good heat preservation effect in the conventional technology, a foaming mode is usually adopted to form a heat preservation layer.

Wherein, for the inner bag that adopts the metal courage body, because influenced by water quality, the inside of inner bag corrodes easily, for this reason, still dispose the magnesium stick on the water tank, the magnesium stick inserts in the inside water storage cavity of water tank.

Magnesium is the lowest potential metal in the electrochemical series and is physiologically nontoxic. Therefore, the magnesium rod protective liner is very ideal. The size of the magnesium rod is directly related to the length of the time for protecting the inner container and the size of the protection effect, and the larger the magnesium rod is, the better the protection effect is and the longer the protection time is.

The water tank is also provided with a water inlet pipe and a water outlet pipe, the water inlet pipe is used for conveying cold water to a water storage cavity formed in the water tank, and hot water in the water storage cavity is output from the water outlet pipe.

For the electric heating part, an electric heating mode such as an electric heating wire, magnetic energy or silicon tube heating can be adopted to heat the water stored in the water storage cavity.

The electric control board is used for receiving detection signals sent by related sensors (such as a water temperature sensor and a flow sensor) and controlling the electric heating component to be powered on and powered off.

When the electric water heater works, the electric control board controls the electric heating part to be electrified and heated, and when the water temperature of water in the water tank reaches a set value, the electric control board controls the electric heating part to be powered off.

As shown in fig. 1, the present invention provides an electric water heater, comprising:

a water inlet pipe 1;

a water outlet pipe 2;

a first inner container 3, wherein a first water pipe 31 is arranged on the first inner container 3;

a second inner container 4, wherein a second water pipe 41 is arranged on the second inner container 4;

a control valve 5;

wherein, inlet tube 1 sets up on first inner bag 3 and communicates with first inner bag 3, and second inner bag 4 communicates with first inner bag 3, and outlet pipe 2 passes through the first water pipe 31 of control valve 5 selective intercommunication and second water pipe 41.

Specifically, this embodiment electric heater disposes two inner bags and stores water, and two inner bags communicate each other, and then in the water intaking process, after cold water entered first inner bag 3 from inlet tube 1, under the water pressure for water in the first inner bag 3 can flow into in the second inner bag 4.

When a user uses hot water, different inner containers can be selected to output the hot water according to different water using conditions.

Specifically, when a user needs to output hot water to the outside from the first inner container 3, the first water pipe 31 is communicated with the water outlet pipe 2 through the control valve 5, at this time, the flow path between the second water pipe 41 and the water outlet pipe 2 is cut off, and the water in the first inner container 3 can be output through the water outlet pipe 2.

Similarly, when the user needs to output hot water to the outside from the second inner container 4, the second water pipe 41 is communicated with the water outlet pipe 2 through the control valve 5, at this time, the flow path between the first water pipe 31 and the water outlet pipe 2 is cut off, and the water in the second inner container 4 can be output through the water outlet pipe 2.

In the use at the actual user's home, the user can switch first inner bag 3 or the outside output hot water of second inner bag 4 through operation control valve 5 alright, like this, alright with abundant water outlet mode in the electric water heater, more be favorable to improving user's use experience nature.
