Embodiment Construction
[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.
[0023] Such as figure 2 and image 3 As shown, it is a structural diagram of the knob assembly proposed in the embodiment of the present application, including an encoder 8, a knob bracket 5, a first housing 3, an adaptive knob sleeve 7 and a housing bracket 4; the encoder 8 is fixed on the circuit board; Adaptive knob sleeve 7 is ring-shaped, and on the ring body of adaptive knob sleeve, there are fixed parts 71 and snap-fit parts 72 arranged oppositely; The inner side of the body forms a U-shaped structure, and the fixed part 71 is inclined to the center of the ring body, so that the U-shaped structure is in the shape of an inverted horn; the fixed part 71 of the adaptive knob sleeve 7 is sleeved on the encoder 8; The adaptive knob cover 7 is coaxially placed...

The invention provides a knob assembly and a washing machine. The knob assembly comprises an encoder, a knob frame, a shell, an adaptive knob sleeve and a shell bracket; the ring body of the adaptive knob sleeve is provided with fixing parts arranged oppositely and clamping parts arranged oppositely; an inverted-horn shape structure is formed between the fixing parts and the inside of the ring body; the fixing parts of the adaptive knob sleeve is connected with the encoder in a sleeved mode; the shell bracket and the adaptive knob sleeve are coaxially arranged on the periphery of the encoder, and fixedly connected in a clamping mode through the clamping parts of the adaptive knob sleeve; the adaptive knob sleeve is connected with the knob frame in a sleeved mode. A knob assembly takes the knob frame as the axis, the shell bracket drives the adaptive knob sleeve to rotate, so as to drive the encoder to rotate. In the rotation process, external and internal stresses act on the knob frame, and the fixing part in an inverted-horn shape has the functions of resolving the external and internal stresses, in order to prevent the encoder from damaging. The knob frame is a closed frame, and the shell bracket covers the center hole of the knob frame to achieve the waterproof function of the knob assembly.
Description
technical field [0001] The invention relates to the technical field of circuit design, in particular to a knob assembly and a washing machine. Background technique [0002] Knobs are widely used in the control panels of electrical appliances such as washing machines, and the purpose of controlling the operation of electrical appliances is achieved by turning them. [0003] Such as figure 1 As shown, the existing knob assembly usually includes an encoder 01, a knob bracket 02 and a casing 03; the center of the casing 03 has a hollow cylinder 031, and the cylinder 031 is directly sleeved on the encoder 01, and the knob bracket 02 is coaxial It is socketed on the periphery of the cylinder 031, and its top surface is in contact with the shell 03, which plays a supporting role for the shell 03; when in use, the shell 03 is rotated, and the encoder 01 is driven to rotate during the rotation of the shell 03 to generate different codes. Coding produces different control signals to...
