Abstract

An electric heating device includes an alternating current step-down circuit provided with a first heating coil having two terminals and a step-down terminal, with the two terminals being used for connecting an AC power source, and a voltage between the step-down terminal and one of the two terminals being less than a voltage between the two terminals; a rectifier circuit electrically connected between the step-down terminal of the first heating coil and any one of the terminals; and a DC element electrically connected to the rectifier circuit.

Description

technical field [0001] The invention relates to an electric heating device, in particular to an electric heating device capable of directly reducing the voltage of an AC power supply and then converting it to a DC power supply so as to meet the demand for low-voltage DC power supply. Background technique [0002] With the advancement of science and technology, electronic products needed in daily life are gradually developed. Taking household appliances as an example, there are electronic devices with corresponding functions for cooking or bathing, such as electric heating devices such as hair dryers or ovens, which can convert electric energy into It is used as heat energy for daily needs such as baking food or drying hair. [0003] Existing electric heating devices are usually directly powered by commercial power (such as: AC 110 or 220 volts). The DC step-down circuit is converted into a low-voltage direct current (such as: DC 12 volts, etc.) to meet the power consumption...
