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. 5-6, the present invention provides an electric water heater, comprising:
a housing (not shown) forming an installation space;
The two inner containers 1000, the end sockets of the inner containers 1000 are provided with flanges;
a water inlet pipe 300, wherein the water inlet pipe 300 extends into one of the inner containers 1000;
a water outlet pipe 400 extending into the other liner 1000;
a connecting 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 liner 1000 is provided with an electric heating element 2000, the electric heating element 2000 being provided on said flange, the first 2001 and second 2002 heating elements extending into the liner 1000; the first electric heating element 2001 is arranged along the axial direction of the liner 1000 and is close to the flange, and the second heating element 2002 is attached to the circumferential wall of the liner 1000;
in addition, two liners 1000 are connected together and located in the housing, and the inlet pipe and the outlet pipe extend to the outside of the housing.
Specifically, for each liner 1000, an independent electric heating component is configured to heat water in the liner, and each liner has a columnar structure as a whole, and the columnar structure can be circular or elliptical. When the liner is installed and used in the user's home, the liner can be vertically installed or can be horizontally installed according to the installation requirement of the user's home.
After the user installs the electric heating device in a standing manner at home, as shown in fig. 5, the two inner containers 1000 are in a standing state as a whole, and in this installed state, the first electric heating device 2001 and the second heating device 2002 are in a standing state as a whole, and the end of the inner container 1000 where the flange is arranged is the lowest water storage position of the corresponding inner container 1000. The first electric heating element 2001 is close to the flange arrangement of inner bag 1000 bottom, and then can follow the bottom of inner bag 1000 through first electric heating element and heat, and then realize the water storage in the effectual heating inner bag 1000 to satisfy the requirement of erectting the installation.
Similarly, after the installation in the user's home in the recumbent installation mode, as shown in fig. 6, the two inner containers 1000 are in the recumbent state as a whole, and in this installation state, the first electric heating element 2001 and the second heating element 2002 are in the state of being arranged horizontally as a whole, and the area where the circumferential wall of the inner container 1000 is located at the lowest part is the lowest water storage position of the corresponding inner container 1000. The second heating component 2002 is close to the circumferential wall of the liner 1000 and is in the lowest water storage position area, so that the bottom of the liner 1000 can be heated through the second electric heating component, and water in the liner 1000 can be effectively heated, so that the requirement of horizontal installation is met.
The inlet of the water outlet pipe and the inlet of the water connection pipe are required to be arranged at a higher water storage position in the liner 1000, so as to meet the requirement of maximizing the hot water output rate at the top of the liner 1000.
For this purpose, the inlet of the outlet pipe is then arranged remote from the flange of the inner container 1000 and, in the radial direction of the inner container 1000, also remote from the second heating element 2002 in the corresponding inner container 1000. Thus, no matter the liner 1000 is installed horizontally and vertically, the inlet of the water outlet pipe can be positioned at a higher water storage position in the liner 1000 so as to effectively output hot water at the top of the liner 1000.
Likewise, the inlet of the connecting water pipe is also arranged away from the flange of the inner container 1000 and also away from the second heating element 2002 in the corresponding 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 liner 1000 and is close to the same circumferential wall of the liner 1000 as the corresponding second heating element 2002.
Specifically, in order to meet the design of maximizing the hot water output rate of the liner 1000, under the condition that water entering the liner 1000 needs to meet the two installation conditions of horizontal and vertical, water newly entering the liner 1000 enters from the lowest water storage position close to the liner 1000. For this reason, by arranging the outlet of the water inlet pipe close to the flange of the inner container 1000 and also close to the circumferential wall of the same side of the inner container 1000 where the second heating member 2002 is arranged, it is possible to ensure that the water inputted 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, whether vertically or horizontally mounted.
Similarly, for the outlet of the connection pipe, the outlet of the connection pipe is located inside the liner 1000 to which the water outlet pipe is mounted and is located near the same circumferential wall of the liner 1000 as the corresponding second heating member 2002.
In particular, the outlet of the connecting water pipe is arranged close to the flange of the inner container 1000 and also needs to be close to the circumferential wall of the same side of the inner container 1000 where the second heating member 2002 is arranged.
In another embodiment, the second heating member 2002 extends along the axis of the liner 1000 in order to improve heating efficiency and uniformity.
Specifically, by designing the second heating member 2002 to be arranged to extend in the axial direction of the liner 1000, in order to achieve an improvement in heating efficiency and a uniform heating of water at the bottom of the liner 1000 in the case of horizontal installation by arranging the second heating member 2002 longer with the circumferential wall of the liner 1000.
In another embodiment, to achieve efficient heating of the water at the bottom of the liner 1000 in case of an upright installation, the first electric heater 2001 is circuitously arranged at one side of the flange.
In another embodiment, as shown in fig. 12-13, for the water heater, an inner container 1000 may be further configured, for which, a water inlet pipe 300 and a water outlet pipe 400 are disposed on the inner container, and an inlet of the water outlet pipe is located inside the inner container and near a circumferential wall of the inner container; the electric heating component is arranged in the inner container, the first electric heating component is close to one end of the inner container, and the second electric heating component is close to the circumferential wall of the inner container and far away from the inlet of the water outlet pipe in the radial direction of the inner container.
