Microwave ovens use magnetrons for heating, but light-wave microwave combination ovens add a light-wave emission source in the microwave oven cavity, which can cleverly use light waves and microwaves to heat food. When the light wave microwave combination oven launched by Galanz is working, the light source and magnetron can be started at the same time. The two can be used alone or in combination, and all functions are controlled by the latest high-tech digital controls. In use, it can be operated with microwaves, light waves alone, or a combination of light waves and microwaves. Therefore, the light wave oven is compatible with the functions of a microwave oven. From a structural point of view, the light wave furnace is equipped with a light wave emitter and a light wave reflector in the upper part of the furnace cavity. The light wave reflector can ensure that the light wave is focused and the heat energy is maximized in the shortest time. This is also an important structural difference between the light wave oven and ordinary microwave ovens. Compared with microwave ovens, light wave ovens have many advantages such as fast heating, uniform heating, and the ability to maximize the nutritional value of food without loss.
