Description

Technical Field

[0001] The utility model relates to the technical field related to air fryers, in particular to a separated air duct structure and also to an air fryer. Background Art

[0002] The air fryer mainly uses air to replace the hot oil in the original frying pan, relying on the convection mechanism and a mechanical fan to circulate the hot air around the food at high speed to cook food. In order to increase the versatility of air fryers, a heating plate is now arranged under the cooking cavity of the air fryer so that the air fryer can realize the function of cooking. Whether it is an air fryer with only the air frying function or an air fryer with the dual functions of air frying and cooking, an air duct member is generally installed thereon. The air outlet on the heat reflecting cover in the air fryer and the air outlet on the volute are respectively connected with the air duct inlet in the air duct member, and the outlet end of the air duct member is placed in the mounting hole on the air fryer. At present, the dual-function air fryer has certain shortcomings in use. When cooking, the hot steam in the pot enters the air duct member, and a part of it is discharged to the outside from the outlet end of the air duct member, and a part of it enters the volute, making the electrical components in the air fryer moist and prone to short circuit, resulting in a short service life of the air fryer; in addition, no sealing measures are provided at the connection between the air duct member and the heat reflecting cover, and the hot steam will also enter the air fryer from the gap at the connection (i.e., the space between the outside of the heat reflecting cover of the air fryer and the outer shell of the pot), thereby making the internal electrical components moist and prone to short circuit, resulting in a short service life of the air fryer. Utility Model Content
