Abstract

The invention discloses a rotation switch as well as a control method and an electromagnetic oven thereof. The rotation switch comprises a knob part, a substrate and a controller, wherein the knob part is rotationally arranged on one side of a transparent panel of a domestic electric appliance; the substrate is arranged on the other side of the transparent panel; the substrate is arranged corresponding to the knob part; at least one light emitting source and at least one light detector are arranged on the substrate; the light emitting source and the light detector are both electrically connected with the controller; a reflection block facing to the substrate is arranged on the knob part; the reflecting part is used for reflecting light reflected by the light emitting source to the light detector; the controller is used for confirming a rotation direction and an angle of the knob part according to the intensity of reflection light detected by the light detector. By adopting the rotation switch, the problem that water cannot be prevented as a hole is formed when a conventional power adjusting knob is used in an electromagnetic oven can be solved, and meanwhile the production cost of the rotation switch is relatively low, so that the cost of the electromagnetic oven is lowered.

Description

technical field [0001] The invention relates to a switch technology, in particular to a rotary switch for adjusting power, a control method thereof and an electromagnetic cooker. Background technique [0002] An induction cooker is a cooker that uses electromagnetic coils to generate electromagnetic waves and utilizes the principle of electromagnetic induction to make iron pans placed on the induction cooker heat up. During use, the power of the induction cooker is generally adjusted through the power adjustment knob. [0003] At present, the mechanical power adjustment knob is widely used on the induction cooker to adjust the power of the induction cooker. When the mechanical power adjustment knob is used on the induction cooker, it is first necessary to open a through hole on the induction cooker panel, and then turn the mechanical power The rotating shaft of the adjusting knob passes through the through hole and is connected with the internal and external mechanical rotat...
