[0026] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, the present invention provides an air fryer comprising: a housing 1, a reflector 2, a motor 3, a first fan blade 4, a second fan blade 5, a heating element 6, and a pot body 7; the reflector 2 is disposed on a partition plate 8 inside the housing 1, and the reflector 2 and the partition plate 8 divide the cavity inside the housing 1 into an installation cavity 1a and a cooking cavity 1b; the motor 3 and the first fan blade 4 are both disposed in the installation cavity 1a; the second fan blade 5 and the heating element 6 are both disposed in the cooking cavity 1b, and are both located inside the reflector 2; the output shaft of the motor 3 extends through the reflector 2 into the cooking cavity 1b, and the first fan blade 4 and the second fan blade 5 are both connected to the output shaft of the motor 3, the first fan blade 4 has a receiving cavity 4a in the middle, and at least a portion of the motor 3 is located in the receiving cavity 4a; the heating element 6 surrounds the second fan blade 5, and the radial projection of the fan blade at least partially coincides with the radial projection of the heating element 6; the pot body 7 can be inserted into the cooking cavity 1b through an insertion port 1c opened in the side wall of the housing 1.

[0028] By using the above technical solution, compared to arranging the components sequentially from top to bottom, the height occupied by the components in the vertical direction is reduced, thereby reducing the height of the air fryer and thus achieving the goal of reducing the packaging and transportation costs of the air fryer.

[0029] In practical applications, the side wall of the casing 1 is provided with an air inlet and an air outlet, and the reflector 2 is provided with a through hole. When the pot 7 containing food is inserted into the cooking cavity 1b through the insertion port 1c, the corresponding cooking mode is selected through the control panel on the casing 1. The motor 3 and the heating element 6 are powered on and start working. The motor 3 drives the first fan blade 4 and the second fan blade 5 to rotate synchronously. During the rotation of the first fan blade 4, outside air enters the mounting cavity 1a through the air inlet and exits the mounting cavity 1a through the air outlet. When the air is discharged, it carries away the heat generated by the motor 3 during operation, so as to avoid the heat in the mounting cavity 1a becoming too high. During the rotation of the second fan blade 5, the hot air generated by the heating element 6 is continuously blown towards the food in the pot, and the hot air circulates in the cooking cavity 1b to heat and cook the food. During the cooking process, some of the hot air in the cooking cavity 1b will enter the mounting cavity 1a through the through hole and then be discharged through the air outlet to maintain the pressure stability in the cooking cavity 1b.

[0030] In some preferred embodiments, the height of the housing 1 is L1, where 150mm ≤ L1 ≤ 200mm, and the height of the pot body 7 is L2, where 40mm ≤ L2 ≤ 80mm. By setting the height range of the housing 1 and the height range of the pot body 7, the height of the air fryer is further limited, resulting in a further reduction in packaging and transportation costs compared to air fryers on the market that are generally higher than 200mm.

[0031] In some preferred embodiments, when the pot body 7 is inserted into the cooking cavity 1b, the distance between the bottom end of the heating element 6 and the inner sidewall of the bottom of the pot body 7 is L3, where 50mm ≤ L3 ≤ 110mm. This technical solution allows the hot air generated by the heating element 6 during operation to be blown more quickly toward the food under the action of the second fan blade 5, thereby improving cooking efficiency.

[0032] In some preferred embodiments, the inner wall of the reflector 2 has a guide slope 2a. In practical applications, the guide slope 2a can guide the hot air in the cooking cavity 1b, so that the hot air can be evenly distributed in the cooking cavity 1b, thereby making the food evenly heated and achieving a good cooking effect.

[0033] In some preferred embodiments, the bottom inner wall of the pot body 7 has multiple upwardly protruding protrusions 7a, which are spaced apart. This design reduces the distance between the food inside the pot body 7 and the heating element 6 after the pot body 7 is inserted into the cooking cavity 1b, allowing hot air to reach the food surface more quickly and heat it, thus improving cooking efficiency.

[0034] In some preferred embodiments, a baking tray 9 or a grill rack 10 is detachably provided inside the pot body 7. In practical applications, when the baking tray 9 or grill rack 10 is placed inside the pot body 7, the food is placed on the baking tray 9 or grill rack 10. There is a predetermined distance between the bottom of the baking tray 9 or the bottom of the grill rack 10 and the inner wall of the pot body 7 (the predetermined distance is the same as the height of the support leg at the bottom of the baking tray 9 or the support leg at the bottom of the grill rack 10). Thus, when the pot body 7 is inserted into the cooking cavity 1b, the distance between the food and the heating element 6 becomes smaller, and hot air can reach the surface of the food more quickly to heat it, improving cooking efficiency. In addition, placing the food on the baking tray 9 or grill rack 10 increases the contact area between the food and the hot air, making the food heated more evenly, thereby resulting in better cooking results.

[0035] In some preferred embodiments, the side wall of the housing 1 is provided with a first viewing area 1d, and the partition plate 8 is provided with a second viewing area 8a. The second viewing area 8a corresponds to the first viewing area 1d. When the pot body 7 is inserted into the cooking cavity 1b, the cooking situation inside the pot body 7 can be seen through the first viewing area 1d and the second viewing area 8a. This technical solution facilitates the operator's understanding of the cooking situation inside the pot body 7. Specifically, the three side walls of the housing 1 are all provided with the first viewing area 1d, thus forming a 270° viewing angle around the circumference of the housing 1, allowing the operator to understand the cooking situation inside the pot body 7 from multiple angles.

[0036] In some preferred embodiments, a heating tube 11 is provided inside the cooking cavity 1b, and when the pot body 7 is inserted into the cooking cavity 1b, the heating tube 11 is located below the pot body 7. In specific applications, the heating tube 11 can work simultaneously with the heating element 6. This not only ensures that the hot air inside the cooking cavity 1b circulates more evenly, allowing the food inside the pot body 7 to be heated evenly, but also allows the cooking cavity 1b to reach the ideal cooking temperature more quickly, thereby improving cooking efficiency.

[0037] In some preferred embodiments, a reflector plate 12 is provided inside the cooking cavity 1b, and the reflector plate 12 is located below the heating tube 11. This technical solution allows the heat generated by the heating tube 11 to be evenly reflected into the cooking cavity 1b under the action of the reflector plate 12, so as to evenly heat the food in the pot 7.

[0038] In some preferred embodiments, the reflector 12 is provided with a recessed groove 12a, and the heating tube 11 is located within the groove 12a. With this technical solution, compared to placing the reflector 12 below the heating tube 11, the vertical height occupied by the heating tube 11 and the reflector 12 is reduced. This allows for a further reduction in the height of the air fryer, thereby further reducing packaging and transportation costs.

[0039] In summary, in one or more embodiments of this utility model, the air fryer of this utility model reduces the height of the air fryer by setting a receiving cavity in the middle of the first fan blade and placing at least a portion of the motor in the receiving cavity, arranging the heating tube around the fan blade, and designing the radial projection of the fan blade and the radial projection of the heating tube to at least partially overlap.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
