[0021] In the embodiment, the stator core 4 is composed of multiple silicon steel sheets 3, and a plurality of ventilation holes 2 are arranged on the stator core 4. By arranging the ventilation holes 2, the heat dissipation capacity of the stator core 4 is significantly improved. During the long-term operation of the steam oven fan, the temperature of the stator core 4 can be effectively reduced to prevent problems such as decline in magnetic properties of the core and aging of insulation materials caused by excessive temperature, so as to ensure that the stator short circuit ring assembly can always work stably within the normal temperature range, maintain the high-efficiency operation state of the steam oven fan, reduce the power loss and component damage risk caused by overheating, further prolong the service life of the equipment, and also help to improve the quality and safety of steamed food.

[0025] The implementation principle of the embodiment is that when the steaming and baking oven starts to work, current flows into the coil winding 8 installed on the outer wall of the coil support 9.

The stator core 4 is composed of a plurality of silicon steel sheets 3, and this structure can effectively enhance the strength and uniformity of the magnetic field. Under the action of the magnetic field, the inner stator 11 starts to rotate. The inner stator 11 is connected with the impeller and other components of the steaming and baking oven, and its rotation drives the impeller to rotate, thereby realizing the air circulation in the steaming and baking oven, allowing the hot air to be uniformly distributed in the steaming and baking oven, so that the food can be steamed and baked in a suitable temperature environment; and in the whole process, the conductive strip 6 in the stator short-circuit ring assembly is made of copper or copper alloy, which has good electrical conductivity, ensuring smooth passage of current, thereby ensuring stable generation of the magnetic field.

In the steaming and baking oven, which is a device that runs for a long time and the stator is prone to heat, the ventilation holes 2 can allow air to circulate and carry away the generated heat, preventing excessive heat accumulation from affecting the performance of the device. At the same time, the protective plate 7 is located between the stator short-circuit ring assembly and the coil assembly, and the arc-shaped design at both ends of the protective plate 7 is matched with the internal structure of the device, which not only effectively blocks impurities such as dust and water vapor from entering, thereby protecting the internal components, but also increases the creepage distance, further improving electrical safety; in addition, the coil support 9 is connected with the external structure through the corresponding second fixing plates 10 at the top and bottom, which can further enhance the stability of the coil assembly, reduce vibration and displacement, ensure the relative position stability of the coil winding 8 and the inner stator 11, maintain the stability and uniformity of the magnetic field, and improve the performance and reliability of the fan.
