Optical wave oven is a kind of household cooking oven, which is called an upgraded version of microwave oven. The principle of optical wave oven is different from that of microwave oven. The output power of the optical wave furnace is mostly 7800 watts, but it has a special "energy-saving" means. The optical wave furnace adopts double efficient heating of light wave and microwave, which can generate huge heat instantly.

The microwave oven is heated by magnetron, but the light wave and microwave combined furnace adds a light wave emission source in the cavity of the microwave oven, which can skillfully use light wave and microwave to heat food. Structurally, the optical wave furnace is provided with an optical wave emitter and an optical wave reflector at the upper part of the furnace cavity. Light wave reflector can ensure that the focused heat energy of light wave is maximized in the shortest time, which is also an important difference between light wave furnace and ordinary microwave oven in structure. Compared with the microwave oven, the microwave oven has many advantages, such as fast heating speed, uniform heating, and keeping the nutritional components of food as much as possible. The main purpose of light wave microwave combined furnace is to greatly improve the heating efficiency of microwave oven, and to maintain the nutritional components of food to the greatest extent during cooking, and to minimize the loss of water when cooking food. In fact, light wave is an auxiliary function of microwave oven, which only works for barbecue. Without microwaves, the microwave oven is only equivalent to an ordinary oven. The optical wave furnaces in the market are all combined furnaces of light wave and microwave, which can be operated by microwave, light wave alone or combined with light wave and microwave. In other words, the microwave oven is compatible with the function of microwave oven.
