Description

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; Fig. 1 is an external perspective view, Fig. 2 is an electric circuit diagram, Fig. 3 is an equivalent circuit diagram of the solid line state in Fig. 2, and Fig. 4 is an equivalent circuit diagram of the solid line state in Fig. 2. FIG. 2 is an equivalent circuit diagram of the state shown by the two-dot chain line. 'In the figure, 2 is the first heater, 5 is the second heater, 7 is the strength changeover switch device, 9 is the voltage relay,
15 is a diode (voltage adjustment element).

Claims (1)

[Scope of utility model registration request] It has a first and a second heater, a first and a second contact, and is provided so that either a state in which only the first contact is closed or a state in which both contacts are closed can be selected. a strong/weak changeover switch device, the second and second heaters are individually connected to the first and second contacts of the strong/weak changeover switch device when the voltage is below a predetermined value, and when the voltage is above a predetermined value; The operation connects the first and second heaters in series to the first contact via the voltage regulating element, and connects the first and second heaters to the second contact without passing through the voltage regulating element. An electric stove comprising: a voltage relay that connects only two voltage relays in series;
