Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a fixing structure for a washing machine knob. Background Art

[0002] In the prior art, a washing machine is an electrical appliance that washes objects to be washed through processes such as washing, rinsing, and dehydration according to preset rules, and can be roughly divided into a pulsator washing machine and a drum washing machine. In order to meet various needs of users, the washing machine has various washing modes and functions. When the user needs to select a washing program, the user rotates a control knob assembly to select programs such as water supply, washing, rinsing, drainage, and dehydration, so as to wash the laundry.

[0003] In order to simplify the operation procedure of the washing machine and reduce the number of buttons, most current washing machines adopt an encoder. The encoder is fixed on a circuit control board and is connected to the main computer control board of the washing machine through a signal line. Various washing modes are selected by rotating the encoder, and signals are transmitted to the main computer control board through the signal line, thereby controlling all washing programs of the washing machine. Usually, the encoder is fixedly connected to the knob, and the two can rotate together. The user can rotate the encoder by rotating the knob, and then select different washing modes according to needs.

[0004] Since the positions of the knob and the encoder on the circuit control board correspond to each other, the knob has a matching installation position on the operation panel. Since the positions of the encoders on different circuit control boards are not completely the same, the position of the knob needs to be adjusted correspondingly. The original operation panel is no longer applicable after the position of the knob is adjusted, resulting in poor versatility of the fixing structure of the knob. Summary of the Utility Model
