Description

Technical Field

[0001] The utility model relates to an air fryer as a cooking utensil, in particular to a novel upper and lower double-pot air fryer with an air sweeping structure. Background Art

[0002] An air fryer is a new type of household appliance that uses high-speed air circulation technology to fry food. The food it makes can contain 80% less fat than traditional electric fryers. It is easy to clean in daily use, and is both safe and economical, making it very popular among people. Some existing air fryer products adopt an upper and lower double-layer body and pot body structure design, such as the application number 202222461172.1 disclosed in the Chinese patent document, the authorization announcement date is 2023.03.03, and the utility model name is "A double-cavity bladeless air fryer"; further, this type of double-layer air fryer has a heating tube and fan blades on the top of the upper layer, and another heating tube and another fan blades at the rear of the lower layer, such as the application number 202322669357.6 disclosed in the Chinese patent document, the authorization announcement date is 2024.04.26, and the utility model name is "A double-layer air fryer"; however, the hot air diversion effect of the above-mentioned products and similar products is poor. Specifically, the lower-layer back-fan air fryer rarely uses the lower left and right sweeping air deflector above the lower pot body, the openings in the bottom of the pot body, and the openings in the back air guide cover to divert the hot air in the lower pot body, resulting in poor hot air diversion effect. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a novel upper and lower double-pot air fryer with an air sweeping mechanism. This solves the technical problem that existing similar lower-layer back-fan air fryers lack effective hot air diversion within the lower pot through the lower left and right air sweeping guide plates above the lower pot body, as well as through openings in the pot body bottom and back air guide cover. This poor hot air diversion effect leads to poor food cooking results. This objective is achieved through the following technical solution.

[0004] A novel upper and lower double-pot air fryer with an air sweeping structure is disclosed. The upper pot body is provided with an upper handle extending from an upper body opening. A groove in the top of the upper cavity above the upper pot body is provided with an upper hot air centrifugal fan blade and an upper heating pipe. The upper motor shaft of the upper motor located at the upper cold air centrifugal fan blade in the upper head extends into the groove in the top of the upper cavity and is connected to the upper hot air centrifugal fan blade. An upper grill is provided at the bottom of the upper pot body. A lower handle extending from the lower body opening is provided on one side of the lower pot body. A through hole in the top of the lower cavity above the lower pot body communicates with a through hole in the back of the lower cavity through a passage in the lower cavity. A lower air duct within the through hole in the back of the lower cavity is provided with a lower heating pipe and a lower hot air centrifugal fan blade. The lower hot air centrifugal fan blade is connected to the lower motor shaft of the lower motor extending into the lower air duct. The lower motor, lower heating pipe, upper motor, and upper heating pipe are connected to a circuit board via wiring. The structural design is characterized in that lower left and right air sweeping guide plates are provided at the through hole in the top of the lower cavity. The lower left and right air sweeping guide plates are hinged by a movable shaft to swing left and right. The above structure improves the guidance of hot air in the lower cavity, guides the hot air on one side of the lower air guide cover to the top of the lower pot body, and further returns to the lower air guide cover to realize the circulation of hot air.

[0005] A pot body ventilation hole is provided on one side of the lower heating pipe and the lower hot air centrifugal fan blade of the lower pot body, and the pot body ventilation hole is aligned with the through hole of the lower air guide cover, so that the hot air in the lower pot body can enter the lower air guide cover through the pot body ventilation hole.

[0006] The lower pot is provided with a lower grill at the bottom, and the lower grill has a hollowed-out plate. The pot body ventilation holes include lower pot body ventilation hole a on one side of the lower pot body above the lower grill, and lower pot body ventilation hole b on the lower side of the lower pot body below the lower grill. This improves the pressure variation and flow guidance of the hot air in the lower pot.

[0007] The aperture on the upper side of the ventilation hole b of the lower pot body is larger than half the aperture of the ventilation hole a of the lower pot body.

[0008] The flat key shaft at the movable shaft is connected to a swing shaft motor, which is connected to a circuit board via a circuit board. The swing shaft motor drives the left and right wind sweeping deflectors to swing through the movable shaft. Thus, the movable shaft and the left and right wind sweeping deflectors are electrically swung by the swing shaft.

[0009] The upper cold air channel in the upper body is connected to the lower cold air channel in the lower body, and is discharged from the exhaust hole on the back side of the upper head of the upper body.

[0010] The upper and lower pot bodies are of the same size, with one side of the lower air guide, lower motor, and lower hot air centrifugal fan blades located at the rear of the lower body protruding from the rear of the upper body. Alternatively, the upper and lower pot bodies are of different sizes, with the rear ends of the upper and lower bodies aligned. This structural design can be customized to meet diverse food processing requirements.

[0011] The utility model has a simple and reasonable structural design, good diversion heating effect, fast food cooking and processing, and a wide range of oven applications; it is suitable for use as a new upper and lower double-pot air fryer with a sweeping structure, and is a structural improvement of similar products.
