Abstract
The utility model relates to an electrical heating device arranged in an electric water heater, namely an electrical heating device for a safety electric water heater. The utility model is composed of a control box regulating power, an electric heating wire, an isolating transformer, a power controller and an electric wire. The utility model has simple structure, convenient use and safety, being an ideal heating device for the safety electric water heater.
Description
The utility model relates to a kind of electric heater unit that is contained in the electric heater, the i.e. electric heater unit of safe electric water heater.
The electrical heating of present electric heater has dual mode, and a kind of is directly-heated type, is heating wire directly to be put into water add hot water, because of heating wire voltage height, easily to cause danger, another kind is an indirect-heating, be to put into water after heating wire is encased with insulating materials to add hot water, but the thermal efficiency is not high.
The purpose of this utility model provides a kind of directly-heated type, is about to heating wire and directly puts into water and add hot water, and keep the voltage of heating wire to be no more than the electric heater unit of the safe electric water heater of 50V.
The utility model is made of control box, heating wire, isolating transformer, power controller and the electric wire of regulating power, wherein control box one end backguy connects power supply, two are connected with isolating transformer and power controller with electric wire respectively in addition, heating wire one end and isolating transformer join, the other end and power controller join, the voltage of isolating transformer control heating wire is at 0-50V, the control box powerstat go into terminal voltage.
The utility model is simple in structure, and is easy to use, safe and reliable, is the heater of desirable safe electric water heater.
Fig. 1 is a principle assumption diagram of the present utility model.
The following describes embodiment of the present utility model:
The utility model is made of control box 1, heating wire 2, isolating transformer 3, power controller 4 and the electric wire 5 of regulating power, wherein control box 1 one end backguys connect power supply, two are connected with isolating transformer 3 and power controller 4 with electric wire 5 respectively in addition, heating wire 2 one ends and isolating transformer 3 join, the other end and power controller 4 join, the voltage of isolating transformer 3 control heating wire 2 is at 0-50V, control box 1 powerstat 3 go into terminal voltage.
This product can reach the power identical with 220V voltage, as reaching the power of 2.2KW, then the voltage of 220V needs the electric current of 10A, be P=V*I=220V*10A=2.2KW, and this product needs the electric current of 44A under the state of voltage 50V, be P=50V*44A=2.2kw, can reach identical power, and safety, can not cause danger, regulate water temperature, then only need to transfer control box 1, change the terminal voltage of going into of transformer 3, thereby just can change the voltage of heating wire 2, but be no more than 50V, so just can change the power of heating wire 2, regulate water temperature.
Claims (1)
1, a kind of electric heater unit of safe electric water heater, it is characterized in that: it is by the control box (1) of regulating power, heating wire (2), isolating transformer (3), power controller (4) and electric wire (5) constitute, wherein control box (1) one end backguy connects power supply, two use electric wire (5) to be connected respectively in addition with isolating transformer (3) and power controller (4), heating wire (2) one ends and isolating transformer (3) join, the other end and power controller (4) join, the voltage of isolating transformer (3) control heating wire (2) is at 0-50V, control box (1) powerstat (3) go into terminal voltage.
