The second magnetic part 206 can be a magnet, and the first magnetic part 116 and the second magnetic part 206 attract each other to realize that the knob assembly 100 is connected with the appliance body 202, so that the knob assembly 100 can be directly adsorbed on the household appliance, and the connection is simple and convenient, and the knob assembly is easy to detach, and is convenient to clean the household appliance and other cleaning works.

Further, the sensing member 204 includes a sensing spring.

In this embodiment, the sensing element 204 specifically comprises a sensing spring, with which a capacitive sensor is constructed. The user triggers response portion 1046 through finger contact and rotatory electrically conductive plastic casing, causes the capacitance value change, and the response spring senses the capacitance value of change, triggers and produces the sensing signal, in transmitting the sensing signal to household electrical appliances's control assembly, control assembly output control signal, and then adjusts household electrical appliances's operating parameter. The induction spring can be used for non-contact measurement, has high sensitivity, good dynamic response and good temperature stability, has a simple structure and low cost, and is suitable as the induction piece 204 in the household appliance.

Further, the number of the sensing elements 204 is multiple, and the multiple sensing elements 204 are distributed in the electric appliance body 202 at intervals along the circumferential direction.

In this embodiment, the number of the sensing members 204 is plural. Specifically, the plurality of sensing elements 204 are distributed at intervals along the circumferential direction in the appliance body 202, and the positions of the plurality of sensing elements 204 correspond to the housing 104. In the use process of the household appliance, a user touches and rotates the conductive plastic shell of the knob assembly 100 through a finger, and rotates the conductive plastic shell to different angles, so that the induction pieces 204 at different positions can be triggered, control signals generated by the control assembly of the household appliance are different, and further working parameters of the household appliance are adjusted.

For example, the household appliance may be an induction cooker, and the fire gear of the induction cooker can be adjusted by rotating the knob assembly 100, i.e., the induction cooker may include a plurality of fire gears. For example, the induction cooker includes four firepower gears, the induction element 204 includes a first induction element, a second induction element, a third induction element and a fourth induction element, when the conductive plastic shell rotates to a first angle, the first induction element is triggered, and the firepower gear of the induction cooker is in the first gear; when the conductive plastic shell rotates to a second angle, the second induction piece is triggered, and the firepower gear of the induction cooker is in a second gear; when the conductive plastic shell rotates to a third angle, the third induction piece is triggered, and the firepower gear of the induction cooker is in a third gear; when electrically conductive plastic casing rotated to the fourth angle, the fourth response piece was triggered, and the firepower gear of electromagnetism stove is in the fourth gear. Through set up a plurality of response pieces 204 in the electromagnetism stove, can change the firepower gear of electromagnetism stove, satisfy the user and cook the needs, promote the user and use experience.
