Description

Technical Field

[0001] The utility model relates to the technical field of food baking, in particular to food baking equipment with an air frying function. Background Art

[0002] Food baking equipment, especially food baking equipment with air frying function, uses heating elements to bake food placed on an inner pot through heat radiation and heat convection. As users' requirements for food baking output and baking effect continue to increase, ordinary electric ovens can no longer meet the actual needs of professional users.

[0003] At present, there are air frying ovens on the market that use shaded pole AC motors and spiral heating tubes placed on the top of the oven. When the heating tube is working, the fan blades installed on the fan rotate unidirectionally, blowing hot air through a specific air duct to the oven liner, and circulating heating and baking the food. However, since ordinary AC fans can only rotate the fan blades unidirectionally to blow out hot air, and the AC motor has a low speed, it is difficult to ensure that the hot air is blown evenly onto the food, and the baking effect cannot meet the needs of users. In addition, AC fans also have the problems of large size, low operating speed, high noise, and long baking time, which seriously affects the user experience and food delivery efficiency.

[0004] Relevant technical personnel have conducted research and development. For example, the utility model patent with Chinese patent number CN201921208593.5 discloses a hot air generating device and an oven having the same, which uses a DC motor to bake food. However, the DC motor assembly is composed of a drive circuit, a rotor, and a magnetic ring stator. Since the temperature of the inner tank core is generally required to be 230°C when the oven is working, it is inevitable that the high temperature of the inner tank is transmitted to the DC motor and the drive circuit on the motor through convection and conduction. In particular, the drive circuit cannot work at high temperature for a long time, which causes premature aging of the DC motor components and shortens the service life.

[0005] Therefore, more effective methods are needed to solve the above drawbacks. Utility Model Content
