OPERAITON THEORY OF MICROWAVE OVEN
1.Microwave is a kind of high frequency electromagnetic wave, which is commonly distributed in the nature. But the existing form of microwave is dispersed so that it cannot be collected together for heating purpose. The key component of magnetron of microwave oven will transform the energy of electricity to microwave and huge energy of microwave field is established under the closed cavity. So the molecule of food is caused to vibrate at very high speed and the friction heat produced will cook the food in a fast way.
2.There is 3 properties of microwave, that is
a)Absorbability: the microwave can cause the excess vibration of molecule of various food so as to obtain the heating purpose. But the infiltration ability is largely depend on the size, thickness and properties of the food.
b)Penetrability: microwave can penetrate through ceramics, glass,
c)Reflectivity: microwave would be reflected by the metal wall of interior cavity so as to establish an even magnetic field, thus can prevent the overheating of partial area.
INSTALLATION OF MICROWAVE OVEN
1)To ensure sufficient ventilation, the distance of the back of microwave to the wall should be at least 10 cm, the side to the wall should be at least 5cm, the free distance above the top surface at least 20 cm.
2)The appliance should be operated with the rear side placed against a wall.
3)Do not place any objects on the top of microwave oven.
4)The position of the oven shall be such that it is far from the TV, Radio or antenna as picture disturbance
or noise may occur.
5)The appliance must be positioned so that the plug is accessible.
6)The microwave oven is intended to be used freestanding and shall not be placed in a cabinet.
7)To keep the microwave oven at a distance from the wall, it is necessary to install a distance limiter
UTENSILS GUIDELINE
It is strongly recommended to use the containers which are suitable and safe for microwave cooking. Generally speaking, the containers which are made of
