1. Smart microwave oven: It can be said that smart microwave oven is a product specially developed for young people. Its characteristic is that you can download various menus from the Internet, and the number of choices is as many as thousands, which saves the process of flipping through meals and cooking. However, at present, the real intelligent microwave oven has not realized intelligent operation, and the product cost of intelligent microwave oven is high and the market positioning is high. The suitable audience types are mostly families with certain economic strength.

Second, microwaves are electromagnetic waves. The microwave oven consists of power supply, magnetron, control circuit and cooking cavity. Under the excitation of the power supply, the magnetron continuously generates microwaves, which are coupled into the cooking cavity through the waveguide system. There is a rotatable agitator near the entrance of the cooking cavity. Because the agitator is a fan-shaped metal, it can reflect microwaves in all directions after rotation, so it can evenly distribute microwave energy in the cooking cavity, thus heating food.

Third, the oven is a sealed electrical appliance used to bake food or dry products, which is divided into household appliances and industrial ovens. Home ovens can be used to process some pasta. Industrial oven is a kind of equipment used for drying products in industry, which has electricity and gas, and is also called oven and drying box.

Fourth, before baking any food, the oven needs to be preheated to a specified temperature to meet the baking time in the recipe. It takes about time to preheat the oven. If it is insufficient, the specified temperature may not be reached. If the preheating time of the oven is too long, it may also affect the service life of the oven.
