To transport in microwave cavity room for microwave from the oral instructions, the (for example) mica that microwave can penetrate is set on waveguide mouth 11 '
Piece 2 ' blocks waveguide mouth 11 ', to prevent oil liquid etc. from entering waveguide 3 ' from waveguide mouth 11 ' and then pollute magnetron etc..
Since mica sheet 2 ' and ontology 1 ' are unlikely to be complete flat state, and mica sheet 2 ' is assemblied in waveguide mouth 11 '
When upper, in order to which mica sheet 2 ' and waveguide mouth 11 ' are easy assembly front and back and have gap certainly.In addition, when assembling mica sheet 2 ', meeting
The position of waveguide mouth is injected after with certain dynamics mica sheet 2 ' being deformed outward, this causes in mica sheet 2 ' and ontology
Certain gap is generated between 1 '.
When cooking food with micro-wave oven, especially roast meat or when chicken, the various oil in food can splash waveguide mouth
11 ' top position as shown in figure 3, oil liquid can readily enter between mica sheet 2 ' and ontology 1 ' from top position, and then produces
Raw condensation, it is for years to have many dusts and adulterate together, microwave heating is added, 11 ' position oil carbon of waveguide mouth is caused.Electricity
Magnetic wave is concentrated in the position of carbonization, and then generates sparking, and micro-wave oven is caused to damage.
If oil is when microwave oven waveguide mouth top or mica sheet surface condense, cleaning can reduce sparking problem in time, but
It is that oil can not then be cleaned when entering between waveguide mouth and mica sheet, therefore sparking problem caused by oil is just unable to improve.
