[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] To prevent cooking fumes from accumulating at the top of the air fryer, the oil-blocking structure provided in this embodiment is applied to the air fryer, such as... Figure 1 As shown, the air fryer includes: a reflector 10 and a cooking chamber 20. An oil-blocking structure is disposed at one end of the reflector 10 near the cooking chamber 20. The oil-blocking structure includes a first blocking part 30.

[0050] like Figure 2 As shown, the first blocking part 30 has a first vent 31, which is connected to the airflow outlet on the reflector 10, and is used to guide the hot air in the cooking cavity 20 out. The first blocking part 30 is used to prevent grease in the cooking cavity 20 from splashing or spreading onto the reflector 10.

[0051] In the above technical solution, during use, due to the setting of the first blocking part 30, the grease in the cooking cavity 20 is prevented from turning into oil fumes at high temperature and splashing directly onto the reflector 10 when the cooking cavity 20 is in the cooking state, and the grease in the cooking cavity 20 is prevented from dispersing onto the reflector 10 when the cooking cavity 20 is not in the cooking state. In addition, when the cooking cavity 20 is working, the hot air in the cooking cavity 20 is discharged through the first vent 31. When the hot air is discharged from the first vent 31, it will cause the air in the cooking cavity 20 to form convection (such as flowing from near the heating tube to the vent), which will cause the high temperature air to continuously wash the surface of the food and shorten the heating time.

[0052] In one of the alternative technical solutions, such as Figure 1As shown, to make the oil-blocking structure and the reflector 10 fit together more compactly, the oil-blocking structure is at least partially attached to the reflector 10. Preferably, to make the first blocking part 30 and the reflector 10 fit together more compactly, the first blocking part 30 is at least partially attached to the side of the reflector 10 facing the cooking cavity 20. It should be noted that the fit between the first blocking part 30 and the cooking cavity 20 is tight, which can prevent hot air from passing through it.

[0053] Optimize the above technical solutions, such as Figure 2 As shown, the first blocking part 30 is arranged at least partially at an angle to the vertical direction, so that the first blocking part 30 forms a guide surface 32 facing the cooking cavity 20; a first vent 31 is provided on the guide surface 32. Because the guide surface 32 is arranged at an angle to the vertical direction, hot air from the cooking cavity 20 can be more easily discharged from the first vent 31. Specifically, the guide surface 32 extends obliquely from the lower side to the upper side, and the angle between the guide surface 32 and the vertical direction is an acute angle, which is in the range of 15-45 degrees, preferably 30 degrees.

[0054] Further optimization of the above technical solutions, such as Figure 3 As shown, one end of the first blocking part 30 is provided with a connecting part 33, and the other end is provided with a flange part 34. The connecting part 33 and the flange part 34 are respectively attached to the side of the reflector 10 facing the cooking cavity 20.

[0055] In the above technical solution, the connecting part 33 and the flanged part 34 are respectively attached to the side of the reflector 10 facing the cooking cavity 20, and a ventilation space is formed between the air guide surface 32 and the side of the reflector 10 facing the cooking cavity 20. Hot air in the cooking cavity 20 is discharged sequentially through the ventilation space and the first vent 31. Of course, in another embodiment, the air guide surface 32 and the side of the reflector 10 facing the cooking cavity 20 are attached together. Preferably, the first blocking part 30 is constructed into a ring structure.

[0056] Further optimization of the above technical solutions, such as Figure 3 As shown, the connecting portion 33 is at least partially bent to form a first folded edge, the first folded edge being fitted to the side of the reflector 10 facing the cooking cavity 20; and / or,

[0057] The flange 34 is at least partially bent to form a second folded edge, which is attached to the reflector 10 on the side facing the cooking cavity 20.

[0058] In the above technical solution, the first folded edge is attached to the side of the reflector 10 facing the cooking cavity 20, which can ensure the compactness of the structure. Specifically, the plane where the first folded edge is located is a horizontal plane. The second folded edge is attached to the side of the reflector 10 facing the cooking cavity 20, which can also ensure the compactness of the structure. Specifically, the plane where the second folded edge is located is a horizontal plane.

[0059] In one of the alternative technical solutions, such as Figure 3 As shown, the first blocking part 30 also has a first connecting position 35, which is disposed on the first blocking part 30. The first connecting position 35 has a first connecting hole, which is connected to the reflector 10 through an elastic connector 40.

[0060] In the above technical solution, the connection between the first connecting hole 35 and the elastic connector 40 is a detachable connection. After the first blocking part 30 is covered with grease during use, the first blocking part 30 can be disassembled for cleaning and then reinstalled after cleaning.

[0061] In one of the alternative technical solutions, such as Figure 1 , Figure 2 and Figure 8 As shown, the oil-blocking structure also includes a second blocking part 50, which is connected to the first blocking part 30. The second blocking part 50 forms an enclosing space for accommodating the hot air assembly, and the second blocking part 50 has multiple second vents 51.

[0062] In the above technical solution, the hot air generated and emitted by the hot air assembly 60 located in the enclosed space is blown into the cooking cavity 20 through the second vent 51 and the ventilation channel. Preferably, the second blocking part 50 is constructed as a ring structure, and a ventilation channel is formed between the first blocking part 30 and the second blocking part 50, and a plurality of second vents 51 are arranged along the peripheral wall of the second blocking part 50.

[0063] The above technical solution is optimized so that the second blocking part 50 and the first blocking part 30 are either an integrated structure or separate structures. In this technical solution, the integrated structure helps to save processes and thus reduce costs, while the separate structure facilitates maintenance and replacement, allowing maintenance personnel to perform corresponding repairs and replacements for any damage to the second blocking part 50 and the first blocking part 30.

[0064] In one of the alternative technical solutions, such as Figure 5 and Figure 6 As shown, the length direction of the second vent 51 is parallel to the central axis of the second baffle 50, facilitating the flow of hot air; or,

[0065] like Figure 4 and Figure 13 As shown, the length direction of the second vent 51 is set at an angle of 15-45 degrees to the central axis of the second block 50 to improve the flow efficiency of hot air; preferably, it is set at 30 degrees.

[0066] In one of the alternative technical solutions, such as Figure 4 and Figure 9As shown, the second blocking part 50 has a second connecting position 52, which is detachably connected to the reflector 10 via an elastic connector 40. At least one of the reflector 10 and the second connecting position 52 has a fixed position, and the other has a second connecting hole. One end of the elastic connector 40 is fixed to the fixed position, and the other end extends and engages within the second connecting hole. Through the cooperation of the elastic connector 40 and the second connecting hole, a detachable connection between the second blocking part 50 and the reflector 10 can be achieved. Furthermore, this detachable connection allows the user to disassemble and clean the baffle structure according to actual needs. Additionally, the elastic connector 40 is a spring-loaded fastener, and there are multiple spring-loaded fasteners. The spring-loaded fasteners can be fixed to the reflector using screws or riveting. Preferably, three spring-loaded fasteners are arranged circumferentially.

[0067] In one of the alternative technical solutions, such as Figure 2 and Figure 5 As shown, after the second blocking part 50 is sleeved on the first blocking part 30, the first connecting hole of the first blocking part 30 and the second connecting hole of the second blocking part 50 are on the same radial direction. One end of the elastic connector 40 is fixed in the fixed position, and the other end passes through the second connecting hole in sequence and is telescopically fastened in the first connecting hole.

[0068] In one of the alternative technical solutions, such as Figure 4 and Figure 6 As shown, the second blocking part 50 is provided with an air guide plate, which is disposed inside the second ventilation opening 51;

[0069] The air guide vane includes a first air guide vane 53 that folds toward the first blocking portion 30; and / or a second air guide vane 54 that folds toward the enclosed space.

[0070] In the above technical solution, the second air guide 54 is used to guide the hot air in the enclosed space to the second vent 51, and the first air guide 53 is used to guide the hot air through the second vent 51 to the ventilation channel. The setting of the air guide 54 improves the efficiency of hot air blowing into the cooking cavity 20.

[0071] Optimize the above technical solutions, such as Figure 6 , Figure 7 , Figure 12 and Figure 14 As shown, the included angle between the outer peripheral surfaces of the first guide vane 53 and the second blocking part 50 is 30-60 degrees, which helps to improve the efficiency of air guidance; Figure 14 As shown, the included angle is preferably 30 degrees;

[0072] Figure 12 and Figure 13 As shown, the included angle between the inner circumferential surfaces of the second air guide 54 and the second blocking part 50 is 30-60 degrees, which helps to improve the efficiency of air guidance.

[0073] In one of the alternative technical solutions, such as Figure 1 and Figure 10 As shown, a filter screen 70 is detachably installed at the bottom of the second blocking part 50. Specifically, the filter screen 70 is a flat filter screen used to increase the area of ​​oil fume blocking. In addition, the connection between the filter screen 70 and the bottom of the second blocking part 50 is a slot type to achieve detachable installation.

[0074] An air fryer includes: the oil-blocking structure described above.

[0075] In an alternative technical solution, to make the structure more compact, the shape of the first blocking portion 30 matches the shape of the reflector 10. Specifically, the reflector 10 includes a central portion and an outer peripheral portion, the shape of which matches the shape of the reflector 10.

[0076] In an alternative technical solution, the hot air assembly 60 includes a fan and a heating element. The fan blows the hot air generated and dissipated by the heating element toward the second vent 51 and along the ventilation channel toward the cooking cavity 20. Furthermore, as... Figure 11 As shown, the heating tube is detachably mounted to the reflector 10 via the hook 80. Preferably, the end of the hook 11 that connects to the reflector 10 is connected by a screw or bolt.

[0077] In an alternative technical solution, when using an air fryer, hot air rotates downwards from the second vent 51 of the second baffle 50 and flows back through the center of the cooking cavity 20. During this process, oil fumes are carried from the food surface to the top of the cavity. Due to the function of the filter 70 and the first baffle 30, most of the oil fumes adhere to their surfaces, thus preventing hard-to-clean parts such as the reflector 10 from being absorbed by oil fumes. Furthermore, the filter 70 and the first baffle 30 are easy to disassemble and can be placed in a dishwasher for cleaning, greatly reducing the difficulty of cleaning.
