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

The electric water heater generally comprises a water tank, an electric heating component, an electric control board and the like, 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 by the water tank, and the electric control board is used for controlling the electric heating component to be powered on and powered off so as to heat the water in the water tank to a set temperature.

For a water tank of an electric water heater, the water tank generally comprises a shell and an inner container, and an insulation layer is formed between the shell and the inner container. Wherein, the shell is generally made of plastic materials so as 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 the requirement.

In addition, the heat preservation that forms between shell and the inner bag, the heat preservation material that commonly uses has: asbestos, sponge, foam, polyurethane foam, etc., and in order to obtain a good heat-insulating effect in the conventional art, a heat-insulating layer is usually formed by foaming.

For the liner adopting the metal liner body, the inside of the liner is easy to corrode due to the influence of water quality, and therefore, the water tank is also provided with a magnesium rod which is inserted into a water storage cavity in the water tank.

Since magnesium is the lowest potential metal in the electrochemical sequence, it is physiologically non-toxic. Therefore, the magnesium rod protective liner is very ideal to be used for manufacturing the magnesium rod protective liner. The size of the magnesium rod is directly related to the time of protecting the liner and the protecting effect, and the larger the magnesium rod is, the better the protecting effect is and the longer the protecting 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 into 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 component, electric heating modes such as electric heating wires, magnetic energy or silicon tube heating can be adopted to heat water stored in the water storage cavity.

For the electric control board, 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 heating component is controlled by the electric control board to be electrified and heated, and when the water temperature of the water in the water tank reaches a set value, the electric heating component is controlled by the electric control board to be powered off.

Referring to fig. 1 and 2, a water heater includes:

a first liner 100 having a heating element 110 disposed therein,

a second liner 200 located above the first liner 100, wherein at least one connection channel is provided between the second liner 200 and the first liner 100;

a water outlet pipe 500 extending from the lower portion of the first liner 100 to the upper portion of the second liner 200 through the connection channel;

a water inlet pipe 600 extending into the first liner 100 from a lower portion of the first liner 100;

wherein, the end of the water inlet pipe 600 is fixedly provided with a baffle assembly 700, and the baffle assembly 700 is adjacent to the side wall of the first liner 100; the flap assembly 700 includes a plurality of shutters 710, the shutters 710 for blocking the lateral flow of hot water in the first liner 100.

After the flap assembly 700 is fixed to the end of the water inlet pipe 600 before the assembly, the flap assembly 700 may be placed in the first liner 100 when the water inlet pipe 600 is assembled to the first liner 100. The baffle assembly 700 can effectively block part of the hot water from flowing to the left side of the first liner 100, thereby improving the flow rate of the hot water from the first liner 100 to the second liner 200, i.e. promoting the hot water to rise.

In some embodiments of the present utility model, the water heater is a dual-tank water heater, the first tank 100 and the second tank 200 are disposed up and down, one end of the heating element 110 is fixed to the right end of the first tank 100, and the other end extends toward the left end of the first tank 100, so that the water temperature on the right side is higher than the water temperature on the left side in the first tank 100. In addition, in this embodiment, there are two connection passages between the first and second liners 100 and 200, namely, a hot water passage 300 and a cold water passage 400, the hot water passage 300 being located on the right side of the cold water passage 400. Because the heating element 110 is only disposed in the first inner container 100 in the water heater, circulation of fluid in the inner container is affected, for example, convection of cold and hot water slowly causes heat to be concentrated in the first inner container 100, especially in the upper right portion of the first inner container 100, energy is wasted, and swirl generated by hot water in the first inner container 100 is larger, convection is affected, so that flow of the hot water channel 300 is smaller, and meanwhile, a portion of the cold water channel 400 close to the hot water channel 300 is affected by the swirl of hot water, so that a temperature difference between the first inner container 100 and the second inner container 200 is increased. However, the baffle assembly 700 may be configured to eliminate the influence, promote the convection circulation of the first liner 100 and the second liner 200, and reduce the temperature difference between the two liners.

In some embodiments of the present utility model, referring to fig. 3 and 4, for the structure of the flap assembly 700, it includes a connection member 720, a first elevating member 730, a top plate 750, and a folding assembly 760.

Specifically, the shielding member 710 is an arc-shaped shielding piece, the shielding piece assembly 700 includes a closed state and an open state, and when the shielding piece assembly 700 is in the closed state, a plurality of arc-shaped shielding pieces enclose a barrel shape; when the flap assembly 700 is in the open state, the spacing of the plurality of arcuate flaps increases. The bending direction of the plurality of arc-shaped blocking pieces is a direction away from the mounting end of the heating element 110.

In some embodiments of the present utility model, with continued reference to FIG. 3, the flap assembly 700 further includes a second lifting member 740 connected to the first lifting member 730 by an elastic member 770, and a folding progression 760 connecting the shutter 710 to the second lifting member 740.

The higher the clamping position of the stop portion and the connecting piece 720, the larger the distance between the shielding pieces 710. That is, the spacing between the shielding member 710 when the connecting member 720 is engaged with the first stop portion 731 is greater than the spacing between the shielding member 710 when the connecting member 720 is engaged with the second stop portion 732.
