Technical Field

The utility model relates to the field of kitchen appliances, in particular to an air-fried microwave oven.

Background

With the development of electronic technology, more and more automatic kitchen appliances appear in the market so as to meet various requirements of people. Particularly in the field of cooking appliances, the electronic control system is integrated in the cooking appliances, so that the cooking appliances can automatically execute cooking programs, and the efficiency of cooking operation is greatly improved.

A microwave oven is a household cooking appliance that is commonly used in life. It is composed of power supply, magnetron, control circuit and cooking cavity. In operation, the power supply provides a high voltage of about 4000 volts to the magnetron, which, under power supply excitation, continuously generates microwaves. The microwave is coupled into the cooking cavity through the waveguide system to heat the food. The microwave oven has the characteristic of high heating speed, but has only a single heating function, and can not realize the baking and cooking of food.

With the improvement of living standard, the oil-free healthy barbecue food is popular with people due to good color, smell and taste. Air fryers have appeared on the market which use hot air for the oil-free baking of food. Although the existing air fryer can realize oil-free baking, the existing air fryer has the difficulty of slow cooking speed. Particularly, when cooking frozen food, a user needs to first thaw the frozen food using a microwave oven and then put the thawed food into an air fryer for cooking. However, the arrangement of the microwave oven and the air fryer in the kitchen at the same time takes up a large space, which affects the utilization efficiency of the kitchen space. Especially for the family with small kitchen area, it is often difficult to arrange a plurality of cooking appliances at the same time.

In recent years, microwave ovens incorporating an air fryer function, called air-fry microwave ovens, have appeared on the market. The air-frying microwave oven integrates an air-frying unit for generating hot air, thereby enabling an air-frying function.
