Rotary knob, temperature control panel comprising same and freezer

Abstract

The invention relates to a rotary knob, a temperature control panel comprising the same and a freezer. The rotary knob comprises a handheld part, an assembly joint part and a running fit part, wherein the running fit part is in running fit with a temperature controller in the temperature control panel; the lower end of the assembly joint part is provided with at least two buckle structures which rotate relative to the temperature control panel and are connected with the temperature control panel in a clamped mode. One buckle structure is additionally provided with a limiting clamping jaw which rotates relative to the temperature control panel and is connected with the temperature control panel in a clamped mode. The limiting clamping jaw and a limiting block on the temperature control panel abut against each other and carry out limiting. The rotary knob is provided with at least two buckle structures which ensure effective connection between the rotary knob and the temperature control panel and stress uniformity together, increase the connection reliability of the rotary knob and guarantee that the rotary knob cannot be taken out easily. On one hand, the limiting clamping jaw improves the connection strength between the rotary knob and the temperature control panel, and on the other hand, the limiting clamping jaw and the limiting block on the temperature control panel jointly play a role of limiting and guarantee the rotating angle of the rotary knob.

Description

technical field [0001] The invention relates to a knob, a temperature control panel and a freezer using the knob, and belongs to the structural design field of the temperature control panel and the freezer. Background technique [0002] At present, there is no electronic freezer using coded switches in the freezer. The control accuracy of the coded switch is higher than that of the mechanical freezers currently on the market. The existing structure of the freezer and the temperature control panel cannot meet the precise control and use requirements of the coded switch. [0003] Freezer and refrigerator products have higher and higher requirements for the knob, especially the knob must not be separated from the thermostat under a certain pulling force. The connection between the traditional knob and the thermostat (or coded switch) is mainly realized through interference fit. Workers squeeze the thermostat, especially the coding switch, which will cause damage due to the for...

Problems solved by technology

The connection between the traditional knob and the thermostat (or coded switch) is mainly realized through interference fit. Workers squeeze the thermostat, especially the coded switch, which will cause damage due to the force, affect the work, and then affect the performance; at the same time, this connection is not reliable, and the accuracy and accuracy of the thermostat or coded switch will be affected during assembly. impact on lifespan
