290*290*149mm.

Common microwave oven cavity volumes generally include 18L, 20L, 23L, 28L, 30L and other specifications. Manufacturers can use the same size oven cavity to develop microwave ovens of different models and microwave output powers.

Theoretically, under the condition that the microwave output power remains unchanged, the larger the furnace cavity, the better the uniformity of heating, but the heating efficiency will be lower. However, this difference will be affected in use. Almost unnoticeable. When other conditions remain unchanged, the larger the furnace cavity, the higher the selling price of the whole machine.

Notes:

1. Avoid overtime heating: put the food in the microwave oven to defrost or heat it. If you forget to take it out, if the time exceeds 2 hours, , should be thrown away to avoid causing food poisoning.

2. Avoid letting the plastic wrap come into contact with food: When using plastic wrap, it is best not to let it come into direct contact with food during the heating process. You can put the food into the bottom of a large bowl and seal the mouth of the bowl flat with plastic wrap. Or cover it directly with glass or porcelain instead of plastic wrap, which can also seal the water vapor and make the heating rapid and even. Before removing food, you can puncture the plastic wrap to prevent it from sticking to the food.

3. Avoid fried foods: high-temperature oil will cause splashing and open flames. If a fire accidentally breaks out in the furnace, do not open the door. Instead, turn off the power first and wait until the fire goes out before opening the door to cool down.

4. Avoid placing the microwave oven in the bedroom, and be careful not to cover the heat dissipation grille on the microwave oven with objects.
