In a first embodiment, referring to fig. 5-6, the present invention provides an electric water heater, including:
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 part 2001 and a second heating part 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 each inner container is integrally of a cylindrical structure, which may be circular or elliptical. When the inner container is installed and used at home of a user, the inner container can be vertically installed or horizontally installed according to the installation requirements of the user at home.
After the two inner containers 1000 are installed in a standing manner in a home of a user, as shown in fig. 5, the first electric heating member 2001 and the second heating member 2002 are integrally erected in this installed state, 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. The first electric heating element 2001 is arranged close to the flange at the bottom of the liner 1000, so that the bottom of the liner 1000 can be heated through the first electric heating element, and water storage in the liner 1000 can be effectively heated, so as to meet the requirement of vertical 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 input into the inner container 1000 from the water inlet pipe is delivered to the vicinity of the lowest water storage position of the inner container 1000 regardless of vertical installation or horizontal installation.
Similarly, as for the outlet of the connection pipe, the outlet of the connection water pipe is located inside the inner container 1000 to which the water outlet pipe is mounted, and is close to the circumferential wall of the inner container 1000 on the same side 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 inner container 1000 for improved heating efficiency and uniformity.
Specifically, by designing the second heating element 2002 to extend along the axial direction of the liner 1000, it is achieved that in the case of horizontal installation, the longer second heating element 2002 is arranged on the circumferential wall of the liner 1000, so as to improve the heating efficiency and enable the water at the bottom of the liner 1000 to be uniformly heated.
In another embodiment, in order to achieve efficient heating of the water at the bottom of the inner container 1000 in the case of vertical installation, the first electric heating element 2001 is arranged to be wound around one side of the flange.
In another embodiment, as shown in fig. 12-13, for the water heater, it can be further equipped with a liner 1000, for this purpose, the liner is provided with a water inlet pipe 300 and a water outlet pipe 400, the inlet of the water outlet pipe is positioned inside the liner and close to the circumferential wall of the liner; the electric heating part is arranged in the inner container, the first electric heating part is arranged close to one end part of the inner container, and the second electric heating part is close to the circumferential wall of the inner container and is far away from the inlet of the water outlet pipe in the radial direction of the inner container. In addition, the outlet of the water inlet pipe is positioned in the inner container and is close to the circumferential wall of the same side of the inner container with the second electric heating element.
