Problems solved by technology

Moreover, the engineering becomes complicated when the stirring fan 50 is installed on the upper and lower sides of the furnace cavity 20 at last.
In addition, if the rivet 55 is forcibly inserted, the wedge 55a is pushed and bent by the holder 53, so that the stirring fan 50 cannot be installed.

Embodiment Construction

[0021] The fixing structure of microwave oven stirring fan of the present invention is described in detail below with reference to accompanying drawing:

[0022] Such as image 3 , 4 As shown, above the oven cavity 100 , that is, on the outside, there is a waveguide 110 for guiding the microwave generated by the magnetron in the electric storage room to the inside of the oven cavity 100 . A synchronous motor M for driving a stirring fan is arranged on one side of the waveguide 110 . The waveguide 110 is arranged under the outer side of the furnace chamber 20 , and several waveguides 110 can also be arranged according to the capacity of the furnace chamber 20 . If the upper and lower sides of the furnace cavity 20 are respectively provided with waveguides 110 , the microwaves flowing into the furnace cavity 20 irradiate the inside of the furnace cavity 100 from the upper and lower sides. A ceramic plate (not shown) is disposed below the interior of the furnace cavity 100 , a...

Abstract

The present invention discloses a fixing structure of stirring fan of microwave oven. It includes rotary fan capable of utilizing rotation to disperse the microwave irradiated into oven cavity interior of microwave oven, combination hole formed and passed through fixer and fixer for supporting rotation of the rotary fan. On the combination hole of the fixer is formed an inclined portion which can make connection component be easily inserted. Said invention utilizes rivet and wedge which can be slided along the inclined portion to make the rotary fan the firmly fixed.

Description

technical field [0001] The invention belongs to a microwave oven device, and in particular relates to a fixed structure of a microwave oven stirring fan for dispersing microwaves irradiated inside the cavity of the microwave oven. Background technique [0002] In general, a microwave oven is a device that cooks food by irradiating a heated object such as food with microwaves generated by a magnetron after power is turned on. Such microwave ovens are classified into domestic microwave ovens equipped with small magnetrons and commercial microwave ovens equipped with large or multiple magnetrons. Microwave ovens can also be distinguished according to the method of heating food. Household microwave ovens generally use a glass plate method that rotates food, and commercial microwave ovens mainly use a stirring fan method that disperses microwaves. Commercial microwave ovens are mainly used in convenience stores that are frequently used or food stores that cook food for a short t...
