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 that forms between shell and the inner bag, commonly used insulation material has: asbestos, sponge, foamed 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.

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.
In a first embodiment, referring to fig. 5-6, the present invention provides a dual-liner electric water heater, which includes:
a housing (not shown) forming an installation space;
two inner containers 1000, wherein flanges are arranged on the end sockets of the inner containers 1000;
the water inlet pipe 300 is extended into one of the inner containers 1000;
the water outlet pipe 400 extends into the other liner 1000;
a connection water pipe 500 installed between the inner containers 1000;
an electric heating part 2000, the electric heating part 2000 including a first electric heating element 2001 and a second heating element 2002;
wherein, each inner container 1000 is provided with an electric heating component 2000, the electric heating component 2000 is arranged on the flange, and the first electric heating component 2001 and the second electric heating component 2002 are extended into the inner container 1000; the first electric heating element 2001 is arranged along the axial direction of the inner container 1000 and close to the flange, and the second heating element 2002 is arranged to be attached to the circumferential wall of the inner container 1000;
in addition, the two inner containers 1000 are connected together and positioned in the shell, and the water inlet pipe and the water outlet pipe extend out of the shell.
Specifically, for each inner container 1000, an independent electric heating component is configured to heat water in the inner container, and the whole inner container is of a cylindrical structure, and the structure of the cylindrical structure may be circular or elliptical. When the liner is installed and used at home of a user, the liner can be vertically installed or horizontally installed according to the installation requirements at home of the user.
After the user installs the two inner containers 1000 in a standing manner at home, as shown in fig. 5, the first electric heating member 2001 and the second heating member 2002 stand in a standing state as a whole, and the end of the inner container 1000 where the flange is disposed is the lowest water storage position of the corresponding inner container 1000. First electric heating member 2001 is close to the flange arrangement of inner bag 1000 bottom, and then can heat from the bottom of inner bag 1000 through first electric heating member, and then realizes the water storage in the effectual heating inner bag 1000 to satisfy the requirement of erectting the installation.
Similarly, after the user installs the inner container in a horizontal installation manner at home, as shown in fig. 6, the two inner containers 1000 are in a horizontal state as a whole, in this installation state, the first electric heating member 2001 and the second heating member 2002 are in a horizontal arrangement as a whole, and the lowest region of the circumferential wall of the inner container 1000 is the lowest water storage position of the corresponding inner container 1000. The second heating element 2002 is close to the circumferential wall of the inner container 1000 and is in the lowest water storage position area, and then can heat from the bottom of the inner container 1000 through the second electric heating element, and then realize the effective water storage in the heating inner container 1000, so as to meet the requirement of horizontal installation.
Wherein, the inlet of the water outlet pipe and the inlet of the connecting water pipe need to be arranged at a higher water storage position in the liner 1000, so as to meet the maximization of the hot water output rate at the top of the liner 1000.
For this purpose, the inlet of the water outlet pipe is arranged away from the flange of the inner container 1000, and is also arranged away from the corresponding second heating member 2002 in the inner container 1000 in the radial direction of the inner container 1000. Therefore, no matter the inner container 1000 is installed horizontally or vertically, the inlet of the water outlet pipe can be located at a higher water storage position in the inner container 1000, and hot water at the top of the inner container 1000 can be effectively output.
Likewise, the inlet of the connection water pipe is also disposed away from the flange of the inner container 1000, and is also disposed away from the corresponding second heating member 2002 in the inner container 1000 in the radial direction of the inner container 1000.
In some embodiments of the present application, the outlet of the water inlet pipe is located inside the inner container 1000 and is close to the same circumferential wall of the inner container 1000 as the corresponding second heating member 2002.
Specifically, in order to satisfy the design of maximizing the hot water output rate of the inner container 1000, the water entering the inner container 1000 should satisfy two installation conditions, namely horizontal installation and vertical installation, and the water newly entering the inner container 1000 enters from the lowest water storage position close to the inner container 1000. For this reason, by disposing the outlet of the water inlet pipe near the flange of the inner container 1000 and also near the circumferential wall of the same side of the inner container 1000 where the second heating member 2002 is disposed, it is possible to ensure that the water fed into the inner container 1000 by the water inlet pipe is delivered to the vicinity of the lowest water storage position of the inner container 1000 regardless of the upright installation or the lying installation.
Similarly, as for the outlet of the connection pipe, the outlet of the connection pipe is located inside the inner container 1000 mounted with the water outlet pipe and is close to the circumferential wall of the same side of the inner container 1000 as the corresponding second heating member 2002.
Specifically, the outlet of the connection water pipe is disposed near the flange of the inner container 1000 and also needs to be near the circumferential wall of the same side of the inner container 1000 where the second heating member 2002 is disposed.
In another embodiment, second heating member 2002 extends along the axis of bladder 1000 for improved heating efficiency and uniformity.
Specifically, the second heating member 2002 is designed to extend along the axial direction of the liner 1000, so that in the case of horizontal installation, the longer second heating member 2002 is arranged on the circumferential wall of the liner 1000, thereby improving the heating efficiency and uniformly heating the water at the bottom of the liner 1000.
In another embodiment, in order to satisfy the condition that the water at the bottom of the inner container 1000 can be heated efficiently in the case of the vertical installation, the first electric heating member 2001 is arranged to be wound on one side of the flange.
