Control panel arrangement of microwave oven controller

Abstract

THe present invention discloses a controller control panel structure of microwave oven. It is characterized by that on the end portion of control panel formed into the external shell of the controller several reinforcing ribs are formed, they and mainly includes longitudinal reinforcing ribs and transverse reinforcing ribs. The longitudinal reinforcing ribs are formed along length direction of control panel ,and the transverse reinforcing ribs are formed along width direction of control panel. The longitudinal reinforcing ribs are formed on the back face of the control panel. Said structure can prevent control panel from producing deformation, and can raise its operation reliability.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a controller control panel structure of the microwave oven constituting the controller shell. Background technique [0002] figure 1 It is an exploded perspective view of a microwave oven structure in the prior art. Such as figure 1 As shown, a cooking chamber for cooking is formed on one side of the cavity 1, and a storage chamber 3 is formed on the other side. The outer box 5 surrounds the cavity 1 to form the top surface and two sides of the microwave oven. The front panel 1' forms the front of the cavity 1, and is provided with a door 7 for selectively communicating the cooking chamber with the outside. An opening 1h is formed on the front panel 1' at the front end of the electric storage compartment 3, and a controller 9 is provided at the front end of the opening 1h. figure 2 It is an exploded perspective view of the microwave oven controller structure in the prior art. Such as ...

AI Technical Summary

Problems solved by technology

But the controller control panel structure of this prior art has following problem, at first, the control panel 10 that constitutes controller 9 outer shells is generally made of synthetic resin, if exposed to various environments for a long time, it can be affected by the environment. Deformation occurs most easily at the upper or lower end of the control panel 10

If the control panel 10 is deformed, the position of the button 15 or the button assembly 15' that is arranged in the button through hole 12 will change, resulting in that the button 15 or the button assembly 15' cannot work or has poor contact.

In order to prevent the deformation of the end of the control panel 10, the upper and lower ends of the control panel 10 are usually fixedly combined on the front panel 1' by using fixing screws, which will cause problems such as an increase in the number of parts, a decrease in the efficiency of assembly operations, and an increase in manufacturing costs.
