Description

Technical Field

[0001] The present application relates to the technical field of kitchen electrical appliances, and more specifically to an air fryer. Background Art

[0002] Air fryers are cooking devices that use heating elements to quickly heat the air and use a high-power fan to make the heated air contact the food, so that the food can be fried. Because the food it makes tastes good, is less oily and contains fewer harmful substances, it is deeply loved by people. Therefore, it is gradually accepted by ordinary families and brings convenience to people's lives.

[0003] Related art air fryers include single-pot air fryers and double-pot air fryers. Single-pot air fryers have one set of heating elements, while double-pot air fryers generally have at least two sets of heating elements; each set of heating elements includes a heating wire and a fan, and the fan blows the heat generated by the heating wire to the inner pot or food cooking cavity to bake the food. Related art air fryers, especially double-pot air fryers, generally set the heating element on the back of the air fryer or on the side away from the user in order to expand the space of the cooking cavity, and the hot air blown by the fan is diffused into the cooking cavity through the air duct; the air duct of the air fryer is generally set above the food cooking cavity, and the air outlet of the fan is located at the end of the air duct away from the user. The air duct extends from the back of the air fryer to the front, and the bottom of the air duct is provided with a plurality of blowing holes connected to the food cooking cavity.

[0004] The air fryer of the related art has the following defects during actual use: because the air outlet of the fan is located at the end of the air duct away from the user, the fan blows hot air into the air duct. The wind pressure is larger and the wind speed is faster at the position close to the fan outlet in the air duct, while the wind pressure is relatively smaller and the wind speed is slower at the position far from the fan outlet. This causes the hot air blown from the blowing holes of the air duct to the food cooking cavity to be uneven. The hot air blown out by the blowing holes closer to the fan outlet has a higher temperature and a faster flow rate, while the hot air blown out by the blowing holes far from the fan outlet has a lower temperature and a slower flow rate. This results in low baking efficiency, uneven cookedness of the baked food, and a poor taste for users. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more, unless otherwise clearly specified.

[0035] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] See also Figures 1 to 8 As shown, the embodiment of the present application discloses an air fryer, which comprises a shell 1, a pot body 2, a heating assembly 3 and a control panel 4, wherein a stainless steel inner pot 100 is connected to the shell 1, and at least one cooking cavity 101 is formed in the inner pot 100, and an insertion port 102 corresponding to and communicating with the cooking cavity 101 is opened on one side of the shell 1 close to the user; at least one pot body 2 is provided, and is provided corresponding to the cooking cavity 101, that is, one pot body 2 can be correspondingly inserted into one cooking cavity 101, and the pot body 2 can be inserted into or out of the cooking cavity 101 through the insertion port 102; similarly, at least one heating assembly 3 is provided, and the heating assembly 3 is provided corresponding to the cooking cavity 101, The heating component 3 is connected to the side of the shell 1 away from the insertion port 102, and the heating component 3 includes an electric heating element 300 and a fan 301, and the fan 301 has a blowing end 302; the electric heating element 300 is connected to the outside of the inner pot 100 and is located on the side of the inner pot 100 away from the insertion port 102, and the fan 301 is connected to the outside of the electric heating element 300, the control panel 4 controls the electric heating element 300 to generate heat, and the fan 301 blows the heat into the cooking cavity 101 through the blowing end 302 and the air duct 5, and at the same time, the heat in the cooking cavity 101 is absorbed by the fan 301, so that a circulation of hot air is formed in the cooking cavity 101, thereby performing cyclic baking on the ingredients.

[0037] It is easy to understand that in order to form hot air circulation in the cooking cavity 101, Figure 2 and Figure 5 As shown, a plurality of air guide holes 104 connected to the cooking cavity 101 are provided on the side wall of the inner pot 100 close to the heating component 3, and a through hole 200 is provided on the side wall of the pot body 2 close to the heating component 3. Under the action of the fan 301, hot air enters the cooking cavity 101 from the fan 301 through the air duct 5, and then flows from the inner cavity of the pot body 2 through the through holes 200 on the side wall of the pot body 2, the air guide holes 104 of the inner pot 100, and the electric heating element 300 to the fan 301, forming an air circulation.

[0038] In the above embodiment, the fan 301 is an axial flow fan, and the electric heating element 300 is an electric heating wire or an electric heating tube.

[0039] In this embodiment, the air fryer further comprises at least one air duct 5, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the air duct 5 includes a top plate 500 connected to the inner pot 100 and a bottom plate 501 connected to the bottom of the top plate 500, and an air flow channel 502 of the air duct 5 is formed between the top plate 500 and the bottom plate 501; therefore, in this embodiment, the air duct 5 is connected to the inner pot 100 and is located above the cooking cavity 101, the air duct 5 is extended from the inside to the outside along the depth direction of the cooking cavity 101, and the inner end of the air duct 5 is connected to the blowing end 302 of the fan 301; the bottom of the air duct 5 is provided with a plurality of air outlets 504 respectively connected to the cooking cavity 101, and the plurality of air outlets 504 are sequentially distributed along the length direction of the air duct 5, and the openings of the plurality of air outlets 504 are sequentially increased in the direction away from the blowing end 302. The air duct 5 is used to uniformly guide the hot air blown by the fan 301 downward into the cooking cavity 101.

[0040] In the above embodiment, the multiple air outlets 504 at the bottom of the air duct 5 are sequentially distributed along the length direction of the air duct 5, and the openings of the multiple air outlets 504 are sequentially increased in the direction away from the blowing end 302 of the fan 301. In this way, after the fan 301 blows the heat generated by the electric heating element 300 into the air duct 5, the wind pressure at the position close to the blowing end 302 of the fan 301 is relatively large, while the wind pressure at the position away from the blowing end 302 of the fan 301 is relatively small. However, in the present application, the openings of the air outlets 504 are sequentially increased in the direction away from the blowing end 302 of the fan 301, and the wind pressure in the air duct 5 is balanced by changing the opening size of the air outlets 504, so that the hot air is evenly diffused into the cooking cavity 101, so that the hot air blown downward from the air duct 5 can evenly reach the surface of the food. Therefore, the hot air blown out of the air duct 5 of the air fryer can evenly diffuse into the cooking cavity 101, thereby improving the baking efficiency and avoiding uneven cooking of the food, so that the food tastes good.

[0041] Further in this embodiment, Figure 4 , Figure 5 and Figure 7As shown, the width of the air duct 5 decreases in a direction away from the blowing end 302. The width of the air duct 5 refers to the height of the internal space of the air duct 5, or the width of the air duct 5 refers to the height of the air flow channel 502, or the distance between the top plate 500 and the bottom plate 501; in this embodiment, the bottom plate 501 is arranged horizontally, and the distance between the top plate 500 and the bottom plate 501 of the air duct 5 decreases in a direction away from the blowing end 302, so that the width of the air duct 5 decreases in a direction away from the blowing end 302; such an arrangement allows the hot air to quickly enter the cooking cavity 101 downward through the air outlet 504 far from the fan 301, and further allows the hot air entering the air duct 5 to quickly and evenly enter the cooking cavity 101 downward through the air outlets 504 at different positions at the bottom of the air duct 5, thereby improving the baking efficiency.

[0042] In the above embodiment, if Figure 5 , Figure 6 and Figure 7 As shown, one end of the airflow channel 502 close to the fan 301 is set as an inlet 503 connected to the blowing end 302 of the fan 301, and the end of the airflow channel 502 away from the fan 301 is set as a closed end; a plurality of guide grilles 303 extending into the airflow channel 502 are provided at the inlet 503. The guide grilles 303 can guide the hot air blown out from the blowing end 302 of the fan 301 to quickly and evenly enter the airflow channel 502 of the air duct 5. In this embodiment, the guide grilles 303 are a plurality of guide holes arranged in the transverse direction of the air duct, and a guide plate extending into the air duct is provided on one side of the guide holes; the guide holes and the guide plates are an integral stamping structure. The guide grilles 303 are formed on the top of the side wall of the inner liner 100 away from the insertion port.

[0043] Further in this embodiment, see Figure 4 and Figure 5 As shown, an air guide plate 304 is connected between the electric heating element 300 and the fan 301, and the upper end of the air guide plate 304 extends to the blowing end 302 of the fan 301; the air guide plate 304 can quickly guide the wind generated by the fan 301 to the blowing end of the fan 301 to enter the air duct 5.

[0044] Further in this embodiment, see Figure 6 and Figure 7As shown, a plurality of wind shielding protrusions 505 corresponding to the air outlets 504 and extending toward the air outlets 504 are provided on the top of the air duct 5. The heights of the plurality of wind shielding protrusions 505 increase in sequence in the direction away from the blowing end 302, so that the distances between the wind shielding protrusions 505 and the air outlets 504 decrease in sequence. The heights of the wind shielding protrusions 505 increase in sequence in the direction away from the blowing end 302 or in the flow direction of the hot air. The wind shielding protrusions 505 play the role of blocking and guiding the hot air toward the air outlets 504. In this way, not only can the hot air quickly enter the air duct 5, and the wind pressure in the air duct 5 is uniform, but also, in combination with the opening size of the air outlets 504, the hot air in the air duct 5 can be uniformly diffused downward to the cooking cavity 101 through the air outlets 504.

[0045] In the above embodiment, a plurality of wind shielding protrusions 505 are integrally formed on the top plate 500 , that is, the wind shielding protrusions 505 are integrally stamped on the top plate 500 , and the lower ends of the wind shielding protrusions 505 are arranged in an arc shape that can guide wind.

[0046] In order to allow the hot air in the air duct 5 to quickly enter the cooking cavity 101 through the air outlet 504, in this embodiment, Figure 6 and Figure 7 As shown, a windshield 506 extending into the air duct 5 and arranged obliquely is connected to one side of each air outlet 504 away from the blowing end 302, and the height of the windshield 506 increases in a direction away from the blowing end 302. The arrangement of the windshield 506 allows the hot air in the air duct 5 to quickly enter the cooking cavity 101 through the air outlet 504; and the height of the windshield 506 is set lower as it is closer to the blowing end 302, in order to balance the flow rate or wind pressure of the hot air flowing into the cooking cavity 101, thereby making the flow rate and wind pressure of the hot air entering the cooking cavity 101 more uniform.

[0047] In the above embodiment, the wind shield 506 is inclined upward and toward the inlet 503 of the air duct 5 , so as to achieve a good effect of shielding the wind and directing the wind toward the air outlet 504 .

[0048] See again Figure 1 to Figure 5As shown, in this embodiment, the air fryer is a double-pot air fryer, specifically, there are two cooking cavities 101, which are sequentially distributed along the height direction of the inner pot 100; there are two pot bodies 2, and the two pot bodies 2 are respectively connected to the two cooking cavities 101; there are two heating components 3, which are respectively arranged corresponding to the two cooking cavities 101; there are two air ducts 5, and the two air ducts 5 are respectively arranged above the two cooking cavities 101, and the two air ducts 5 are respectively connected to the blowing ends 302 of the fans 301 of the two heating components 3. In the embodiment of the double-pot air fryer, the upper air duct 5 is connected to the top of the inner pot 100, and the lower air duct 5 is connected to the middle of the inner pot 100, and the lower air duct 5 divides the inner pot 100 into two upper and lower independent cooking cavities 101, so that the food in the two cooking cavities 101 will not have mixed flavors.

[0049] In other embodiments, the air fryer may also be a single-pot air fryer or a three-pot air fryer. As for the single-pot air fryer, it only has one cooking cavity 101, one pot body 2 and one heating component 3, etc.; and the cooking cavity 101, pot body 2 and heating component 3 corresponding to the three-pot air fryer may also be set to three, or the heating component 3 may be set to two, etc.

[0050] In some embodiments, Figure 1 and Figure 8 As shown, a groove 103 is provided on the outer wall of the housing 1, and a control panel 4 that can move forward and backward can be rotatably connected in the groove 103. That is, the control panel 4 can be rotated and extended out of the groove 103 when in use, and can be retracted or folded into the groove 103 when not in use. This arrangement is convenient for users to operate at different use angles, and further saves space in the housing 1. When unfolded for use, it can be kept away from heat sources for convenient heat dissipation.

[0051] In some embodiments, Fig. 9 As shown, the pot body 2 of the air fryer is connected with a transparent window 201 for viewing the food inside the pot body 2.
