Abstract

The invention relates to a rotary switch, its control method and an induction cooker. The rotary switch includes: a knob, a substrate and a controller, wherein the knob is rotatably arranged on one side of a light-transmitting panel of a household appliance, and the substrate is arranged on a light-transmitting panel. On the other side of the panel, the substrate and the knob part are arranged correspondingly; at least one light emitting source and at least one light detecting part are arranged on the substrate, wherein both the light emitting source and the light detecting part are electrically connected to the controller; The reflective block is used to reflect the light emitted by the light source to the light detection part, and the controller is used to determine the rotation direction and angle of the knob part according to the intensity of the reflected light detected by the light detection part. The rotary switch of the present invention solves the problem that the existing power adjustment knob cannot be waterproofed due to opening holes when it is used in an electromagnetic cooker, and at the same time, the production cost of the rotary switch is low, thereby reducing the cost of the electromagnetic cooker.

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...
