Abstract
Description
Technical Field
[0001] This utility model relates to a heating structure for an air fryer, and more particularly to a rear heating structure for an air fryer. Background Technology
[0002] Traditional air fryers are basically designed with a drawer-style pot body, an electric heating element installed at the top of the pot body, and an air supply system installed above the heating element. The air supply system delivers the hot air heated around the heating element into the pot body to heat and cook the food inside.
[0003] The drawbacks of this structure are as follows: This top-to-bottom (air supply system, heating element, and pot body) design makes the air fryer quite tall, especially when designed with two pot bodies. This not only detracts from the aesthetics but also makes the product prone to instability when placed on a shelf. Furthermore, the horizontal installation of the heating element and the top-to-bottom direct airflow result in short contact time between the heating element and the flowing air, leading to low heat utilization. This direct airflow also causes uneven heat distribution, resulting in uneven heating of the food and affecting its texture, ultimately impacting the overall quality and performance of the air fryer. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a rear heating structure for an air fryer, addressing the shortcomings of existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following measures: An air fryer rear heating structure includes an air fryer body, a drawer-type structure housing a pot body inside the air fryer body, an air supply system mounted on a motor bracket located on the rear side of the pot body inside the air fryer body, an electric heating tube vertically arranged between the pot body and the air supply system, the electric heating tube being fixedly installed in the air fryer body via an electric heating tube bracket plate, a front fan blade connected to the motor shaft of the air supply system passing through the electric heating tube bracket plate, the front fan blade being located between the electric heating tube and the electric heating tube bracket plate, a side plate being provided on the edge of the electric heating tube bracket plate, a baffle plate vertically installed between the rear side wall of the pot body and the electric heating tube, the top of the baffle plate and the side plate of the electric heating tube bracket plate forming a hot air outlet, an upper air guide plate being provided above the pot body, the upper air guide plate being fixedly installed on a frame inside the air fryer body, the inner end of the air guide plate having a guiding slope facing the hot air outlet; The top of the wind deflector is bent outward horizontally to form a supporting top plate, and an air diversion plate is vertically installed in the middle of the supporting top plate. The air diversion plate is installed along the front-to-back direction. The height of the air guide slope gradually decreases from the inner end to the outer end, and the air guide slope extends to the middle position of the air guide plate. The air fryer body is a double-pot structure with an upper and lower section; The rear side wall of the pot body is provided with a circulating air vent grid, which is distributed to the left and right bottom corners of the rear side wall of the pot body. The wind baffle plate on the rear side of the pot body is provided with mesh holes corresponding to the positions of the circulating air vent grid. The outer shell of the air fryer body is equipped with multiple airflow circulation grids.
[0006] The beneficial effects of this utility model are: practicality, novel structure, rear-mounted air supply system and heating device, which reduces the overall height of the product, making it particularly suitable for use in double-layer air fryers. The improved air guide structure avoids hot air being blown directly into the pot without being diverted and guided, which would cause uneven heating of the food inside the pot.

[0014] An air fryer rear heating structure includes an air fryer body 1, a drawer-type pot body 2 installed inside the air fryer body 1, an air supply system 4 mounted on a motor bracket 3 located at the rear of the pot body 2 inside the air fryer body 1, an electric heating tube 5 vertically arranged between the pot body 2 and the air supply system 4, the electric heating tube 5 being fixedly installed inside the air fryer body 1 by an electric heating tube bracket plate 6, and a front fan blade 7 connected to the motor shaft 401 of the air supply system 4 passing through the electric heating tube bracket plate 6. Located between the electric heating tube 5 and the electric heating tube support plate 6, the edge of the electric heating tube support plate 6 is provided with a side plate 601. A baffle plate 8 is vertically installed between the rear side wall of the pot body 2 and the electric heating tube 5. The top of the baffle plate 8 and the side plate 601 of the electric heating tube support plate 6 form a hot air outlet 100. An upper air guide plate 9 is provided above the pot body 2. The upper air guide plate 9 is fixedly installed on the frame inside the air fryer body 1. The inner end of the air guide plate 9 is provided with an air guide slope 901 facing the hot air outlet 100.
[0015] like Figure 1-7 As shown, when cooking or heating food inside the pot 2, the front fan blades 7 of the air supply system 4 blow the air heated by the electric heating element 5 out of the hot air outlet 100. The hot air is then guided into the pot 2 by the guide vane 9's inclined surface 901 to cook or heat the food inside. An air diversion plate 10 is provided within the area of the hot air outlet 100. The air diversion plate 10 diverts the hot air to both sides, allowing it to be blown more evenly into the pot 2, promoting uniform heating of the food and preventing localized burning.
[0016] This structure features a rear-mounted heating element and air supply system, reducing the overall height of the product and making it particularly suitable for the design and use of double-layer air fryers.
[0017] like Figure 2 and Figure 5 As shown, the top of the wind deflector 8 is bent outward horizontally to form a supporting top plate 801. An air diversion plate 10 is vertically installed at the middle position of the supporting top plate 801, and the air diversion plate 10 is installed along the front-back direction.
[0018] like Figure 1 and Figure 3 The height of the guide slope 901 gradually decreases from the inner end to the outer end, and the guide slope 901 extends to the middle position of the guide plate 9, which facilitates the entry of hot air into the pot body 2.
[0019] The air fryer body 1 is a double-pot structure with an upper and lower section.
[0020] like Figure 2 and Figure 5As shown, a circulating air venting grid 201 is provided on the rear side wall of the pot body 2. The circulating air venting grid 201 is distributed at the left and right bottom corners of the rear side wall of the pot body 2. The wind baffle 8 on the rear side of the pot body 2 is provided with mesh holes 802 corresponding to the positions of the circulating air venting grid 201.
[0021] The outer shell of the air fryer body 1 is equipped with multiple airflow circulation grids 11.
