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 are 3 properties of microwave:
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 depends on the size, thickness and
properties of the food.
b) Penetrability: microwave can penetrate through ceramics, glass, temperature-resistant plastics. It is
required to use the containers whose material have good microwave penetrability to achieve best
heating result. Please see the below utensils guide.
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 from the back of microwave to the wall should be
above10cm, the side to the wall above 5cm, the top to the ceiling above 20 cm.
2) Do not place any objects on the top of microwave oven.
3) Keep the microwave oven far from the TV, Radio or antenna as picture disturbance or noise may
occur.
4) Keep the plug to accessible to the socket.
5) The microwave oven is intended to be used freestanding and shall not be placed in a cabinet.
6) To keep the microwave oven at a distance from the wall, it is necessary to install a distance limiter.
Here,we have two types of distance limiters in different shape for your reference,however,the case
will be that first you take the distance limiter out of the accessories bag in the cavity, and then decide
between the alternatives given below to make an available installation.
