Problems solved by technology
The present invention can solve the deficiencies existing in the prior art. It has the function of rotating segment display and is simple and convenient to operate. However, during the further development of this prior art solution, it was found that the silicone switch can transmit pressure on the one hand, and has elasticity on the other hand. , the elastic potential energy stored after deformation can push up the columnar structure of the fixed body to help it return to its original position, but the service life of the silicone switch is limited. After long-term use and oxidation, the ability of the silicone switch to restore its shape is reduced. , which causes the use effect of the support structure for the knob structure of the washing machine to deteriorate, causing troubles for users

The invention relates to a supporting structure for a rotary knob structure of a washing machine. The rotary knob structure of the washing machine comprises a rotary knob assembly, a pressing assembly, a display screen assembly, an encoder and a PCBA board; the rotary assembly can transmit pressing force to the pressing assembly; the PCBA board is located below the pressing assembly; a switch key of the pressing assembly is electrically connected with the PCBA board; when the pressing assembly descends due to external force, the switch key is turned on, and a command on the display screen assembly is determined; the supporting structure is arranged in a switch support of the pressing assembly above the switch key and used for transmitting pressing pressure of the pressing assembly; the supporting structure is characterized by comprising a hard sliding block, an elastic piece and a support structure; the top face and the bottom face of the switch support are provided with an inlet channel and an outlet respectively; and the sliding block is installed in the inlet channel in a sliding mode. The structure is simple and the use is convenient.
Description
technical field [0001] The invention relates to the technical field of washing machines, in particular to a supporting structure for a knob structure of a washing machine. Background technique [0002] At present, most of the control panels of washing machines are equipped with knobs. The knob and multiple buttons work together to realize the setting and switching of program functions such as washing mode or washing time. The existing washing machine knob buttons are scattered and have no rotation segment display function, which is very inconvenient to operate and affects the user experience. [0003] The prior art PCT / CN2019 / 094608 discloses a supporting structure for a knob structure of a washing machine. The knob structure includes a knob component, a display component, a pressing component and a PCBA board. The knob assembly includes a knob rotating seat, a fixed body and a knob decoration ring. The upper end of the knob rotating base is provided with accommodating g...
