Problems solved by technology
[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 the household appliance through the connection between the knob and the panel, causing damage to its internal parts
[0006] Three: The knob is easy to accumulate dirt and is not easy to clean

A rotary knob structure comprising an induction rotary knob (1) which is disposed on an upper surface of a panel (2) of a household electric appliance, wherein the interior of the induction rotary knob (1) is provided with a metal induction layer (7); a plurality of induction coils (9), wherein the plurality of induction coils (9) are arranged on a lower surface of the panel (2) corresponding to the metal induction layer (7) in a manner whereby every two induction coils are adjacent to each other; and an angle determining circuit board (6) which is connected to the plurality of induction coils (9) and is used for obtaining an induction parameter of the plurality of induction coils (9) and determining a current rotating angle of the induction rotary knob (1) according to the induction parameter of the plurality of induction coils (9). Also provided are a rotating angle determining method, a rotating angle determining device and a household electric appliance comprising the rotary knob structure. The rotary knob structure can prolong the service life of the induction rotary knob and other related parts and can accurately determine the rotating angle of the rotary knob, thereby achieving 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...
