Problems solved by technology

[0003] At present, many functional gears on the refrigerator are operated by buttons such as display boards, which is sometimes inconvenient to operate; now the present invention designs a knob device with an encoder for the refrigerator, by rotating the knob to select the desired function of the user, The metal knob is exquisite in appearance and novel in style. The user corresponds to 4 gears, and each gear has an indicator light. When selecting which gear, the corresponding indicator light is on, and it can be rotated clockwise and counterclockwise. Transmit the light on the PCB board, the bottom of the metal knob is bright

Abstract

The invention discloses an encoder provided rotary knob device for a refrigerator, and relates to the field of refrigerator accessories. In the encoder provided rotary knob device for the refrigerator, a PCB is fixed to an operation panel; indication lamps are further arranged on the operation panel and are connected with the PCB; a supporting seat is clamped on the inner side of a metal rotary knob, an encoder and a light guide column are fixed to the PCB, and an assembly formed by the metal rotary knob and the rotary knob supporting seat is clamped on the encoder; and assembling is completedthrough cooperation between buckle structures. Through the arrangement of the encoder provided rotary knob device, function selection is achieved through rotating of the rotary knob, and the device gets rid of the manner that functions are selected through keys and buttons in previous refrigerators; the rotary knob supporting seat and the metal rotary knob are limited and mounted through a clampgroove, mounting is simple, and screw driving and tools are not needed; and the structure is simple and reliable.

Description

technical field [0001] The invention belongs to the field of refrigerator accessories, in particular to a knob device with an encoder for a refrigerator. Background technique [0002] With the development of science and technology; people's living standards are getting higher and higher; refrigerators have become an indispensable electrical appliance in people's daily life; basically every household has a refrigerator. [0003] At present, many functional gears on the refrigerator are operated by buttons such as the display board, which is sometimes inconvenient to operate; now the present invention designs a knob device with an encoder for the refrigerator. By rotating the knob, the user can select the desired function. The metal knob is exquisite in appearance and novel in style. The user corresponds to 4 gears, and each gear has an indicator light. When selecting which gear, the corresponding indicator light is on and can be rotated clockwise and counterclockwise. Transm...
