The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 2 is a process flow chart of the operation of the electric water heater according to the embodiment of the present invention, as shown in fig. 2, a heating chamber in the prior art is divided into two heating chambers a and B, and when the hot water in the heating chamber a is output to a certain amount (a threshold), the controller is triggered to close the water outlet a and open the water outlet B. Similarly, when the hot water in the heating chamber B is output to a certain amount (a threshold value), the controller is triggered to close the water outlet B and open the water outlet A, and the water outlet A is circularly reciprocated to keep the continuity of water outlet.
In the present embodiment, a movable partition is provided inside each heating chamber A, B, and the initial position is located at the cold water inlet, which is used to isolate the hot water heated in the chamber from the incoming cold water, and prevent the hot water from exchanging heat.
When the power supply is turned on to heat the heating chamber A, the chamber A is powered off and the water outlet of the chamber A is opened according to the boiled water operation of a user when the temperature of the chamber A reaches a set value. When the A chamber outputs hot water, the B chamber is powered on to heat. When the hot water output by the chamber A reaches a certain amount, the movable partition triggers the controller to close the water outlet A, and the movable partition resets.
And when the temperature of the chamber B reaches a set value, the chamber B is powered off and the water outlet of the chamber B is opened based on the triggering of the first movable partition plate. When the B chamber starts to output hot water, the A chamber is connected with the power supply to start heating. When the hot water output by the chamber B reaches a certain amount, the movable partition triggers the controller to close the water outlet B, and the movable partition resets. The operation is repeated and alternated. When the heating power satisfies a reasonable value, continuous hot water supply can be realized.
According to the technical scheme, the movable cold and hot water partition isolation baffle is arranged in the heating chamber to prevent cold and hot water in the heating chamber from exchanging heat energy. The initial position of the isolation barrier is at the cold water inlet end. The baffle moves reasonably along with the change of the space occupied by the cold water and the hot water. When the heated hot water is less than a certain amount, the water outlet of the heating chamber is closed, and the baffle returns to the initial position. When water is supplied to the outside, the heating chamber is powered off, and the use safety is guaranteed. The two heating chambers are arranged, and energy can be saved by alternately heating.
In summary, with the aid of the technical solution of the embodiments of the present invention, the movable partition board in the heating chamber effectively reduces the heat exchange between the hot water and the cold water, improves the quality (almost constant) of the hot water at the outlet of the heating chamber, and improves the satisfaction of the user (the temperature of the water outlet of the original solution is continuously changed from high to low, and the user needs to continuously adjust the water mixing valve). The two heating chambers are heated alternately, so that energy conservation can be effectively realized. The heating chamber is powered off and water supply is carried out, so that the safety is improved. The power of the heating rod is reasonably set according to the maximum water yield and the proper temperature, so that continuous and stable hot water supply can be achieved, and waiting is avoided.
