Abstract

The invention provides a rotary knob structure, a rotating angle determining method and device, and a household electric appliance. The rotary knob structure comprises an induction rotary knob which is disposed on the upper surface of a panel of the household electric appliance, wherein the interior of the rotary knob is provided with a metal induction layer; a plurality of induction rings which are arranged on the lower surface of the panel corresponding to the metal induction layer in a manner that each two induction rings are adjacent to each other; and an angle determining circuit board which is connected to the plurality of induction rings and is used for obtaining the induction parameters of the plurality of induction rings and determining the current rotating angle of the induction rotary knob according to the induction parameters of the plurality of induction rings. Through the technical scheme of the invention, the structure can prolong the service life of the induction rotary knob and other related parts, can accurately determine the rotating angle of the rotary knob, and achieves the more accurate control of the household electric appliance.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a knob structure, a method for determining a rotation angle, a device for determining a rotation angle and a household appliance. Background technique [0002] At present, in the related art, the knobs on the household appliances are all mechanical structures, which are rotated by mechanical contacts, and then the household appliances are controlled. [0003] But the knob in the prior art scheme has the following defects: [0004] One: Mechanical wear is inevitable when relying on mechanical contacts to rotate, resulting in a serious shortage of life of the knob, and the accuracy of controlling the machine through mechanical contacts is poor and the mechanical device is complicated. [0005] Two: The knob of the mechanical structure needs to pass through the panel to connect with the inside of the household appliance, which may easily cause sewage to enter t...
