(1) The barbecue tube in the microwave oven is a magnetron, which is a microwave generator, and can generate microwaves with a vibration frequency of 2.45 billion times per second. This invisible microwave can penetrate the food to a depth of 5cm, and make the water molecules in the food move with it. The intense movement generates a lot of heat energy, and the microwave heats the food from the inside out. Copper tubes or quartz tubes are widely used in the barbecue tubes of microwave ovens, which are difficult to cool after heating and are easy to cause burns; The thermal efficiency of quartz tube is not too high.

(2) The light wave oven is also called light wave microwave oven. The barbecue tube of the light wave oven is changed from quartz tube or copper tube to halogen tube (i.e. light wave tube), which is heated by far infrared heating principle. After the power supply is turned on, the infrared component in the oven can generate a high temperature of 600℃-700℃ in a few seconds (the highest temperature of the induction cooker is 300℃), and then all the light energy is condensed together by imported energy-gathering reflective materials and reflected on the oven panel. The microwave oven also has fast cooling speed, higher heating efficiency and no scorching, thus ensuring the color of food.

2. Different effects on human body.

(1) Microwave ovens radiate microwaves, which is harmful to health.

(2) The infrared light emitted by the infrared wave oven has an auxiliary physical therapy effect on the human body. The principle of optical wave oven is the thermal cycle of quartz tube heating fan, which has no radiation, is healthy and environment-friendly, and the cooked food is delicious and healthy, so pregnant women and children can safely eat it.

3. Differences in cost

(1) Copper tubes used in microwave ovens are slightly cheaper.

(2) The cost of the optical wave tube used in the optical wave furnace is only a few dollars more than that of the copper tube or quartz tube.

4. Different uses

(1) The food containers in microwave ovens must be made of insulating materials.

(2) The microwave oven does not pick pots and pans, and has many functions such as cooking, steaming, stewing, stewing, cooking, milk heating, sterilization, heating, dehumidification and moisture prevention.

Note: In fact, most of the light wave ovens on the market are light wave microwave ovens. The combined light wave and microwave ovens greatly improve the heating efficiency of microwave ovens and light wave ovens. They use these two different heating principles to heat at the same time, and light waves and microwaves simultaneously heat food in a closed oven cavity at high speed, which completely solves the phenomenon of uneven heating and uncooked and cooked in the past, and has higher thermal efficiency. And in the process of cooking, the nutritional components of food are kept to the greatest extent, and the loss of water is avoided as much as possible when cooking food.
