Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, specifically to an inner pot assembly and an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that uses hot air to "fry" food. Instead of hot oil, the air fryer uses hot air to create a circulating hot airflow in the sealed pot to cook the food. At the same time, the hot air can also blow away the moisture on the surface of the food, giving the ingredients an effect similar to deep-frying.

[0003] In related technologies, the inner pot component of an air fryer includes an inner pot and a viewing panel. The viewing panel is installed on the outer wall of the inner pot, and a viewing window is provided on the side wall of the inner pot. Users can observe the cooking process of the food in the inner pot through the viewing panel and the viewing window. However, when the air fryer is working, some airflow will enter the heating chamber through the viewing window, which will disrupt the normal circulation path of the air duct and cause air loss. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this utility model proposes an inner pot assembly that can meet the needs of visualization, reduce air volume loss, and improve the circulation effect of hot air.

[0006] This utility model also proposes an air fryer.

[0007] The inner pot assembly of this utility model includes: an inner pot and a viewing panel. The inner pot has a side plate, and the viewing panel is disposed outside the inner pot and defines a wind-guiding cavity with the side plate. The side plate is provided with a viewing window and a wind-blocking part. The viewing window is arranged opposite to the viewing panel. The outer edge of the viewing window has a windward side. At least a portion of the wind-blocking part is disposed on the windward side of the viewing window and is located inside the wind-guiding cavity.

[0008] According to the inner pot assembly of this utility model, by arranging the viewing window and the viewing panel opposite each other, the user can observe the cooking of food in the inner pot through the viewing panel and the viewing window. When the circulating hot airflow enters the air guide cavity, since at least part of the wind baffle is located on the windward side of the viewing window and is located in the air guide cavity, some of the airflow will impact the wind baffle to change the flow direction of the airflow, so that the amount of airflow entering the inner pot through the viewing window is greatly reduced. This can reduce the airflow loss when the airflow passes through the air guide cavity, which is beneficial to improving the circulation effect of hot air.

[0009] Optionally, the windward side includes a first windward side, which is located above the viewing window. When the air fryer is working, most of the airflow flows in the air guide cavity from top to bottom. Therefore, placing the wind deflector on the first windward side can block most of the airflow entering the viewing window, thereby reducing the flow of airflow entering the inner pot through the viewing window.

[0010] Optionally, the windward side includes a second windward side, which is located on one side of the viewing window in the left-right direction. When the airflow moves within the air guide cavity, under the rotation of the fan, the airflow has a horizontal component force while flowing downward, meaning the airflow flows downward at an angle. Since the second windward side is located on one side of the viewing window in the left-right direction, it can block the airflow that enters the viewing window at an angle, thereby further reducing the flow rate of airflow entering the inner pot through the viewing window.

[0011] Optionally, the outer edge of the viewing window also has a leeward side. Along the airflow direction within the air guide cavity, the windward side is located upstream of the leeward side. The windproof portion includes a flange, with a first side of the flange connected to the windward side and a second side of the flange extending obliquely towards the leeward side. Because the first side of the flange is connected to the windward side and the second side of the flange extends obliquely towards the leeward side, when the airflow passes through the flange, the direction of the airflow can be changed, causing the airflow to flow away from the viewing window. This reduces the amount of air entering the inner pot through the viewing window. Furthermore, the flange has a simple structural design and is easy to manufacture.

[0012] Optionally, the distance between the first side and the second side of the flange is L1, where 3mm≤L1≤6mm. By designing α using the above parameters, the inner pot assembly of this invention can reduce the flow rate of air entering the inner pot through the viewing window and minimize adverse effects on the airflow within the air guide cavity, thus ensuring the circulation effect of the air duct in the air fryer.

[0013] Optionally, the angle between one side of the flange along its thickness direction and the plane containing the viewing window is α, where 15°≤α≤40°. This improves the wind-blocking effect of the flange, reducing the amount of airflow entering the inner pot through the viewing window and minimizing airflow loss.

[0014] Optionally, there are multiple viewing windows, which are spaced apart along the vertical direction and the horizontal direction of the side panel. This arrangement of multiple viewing windows increases the user's field of vision for the food inside the pot while reducing the amount of airflow entering the viewing windows.

[0015] Optionally, the distance between two adjacent viewing windows along the vertical direction of the side panel is ΔH, and the distance between two adjacent viewing windows along the horizontal direction of the side panel is ΔW, where 0 < ΔH ≤ 5mm and 0 < ΔW ≤ 5mm. When the values ​​of ΔH and ΔW are less than or equal to 5mm, the airflow guiding effect of the flange at the upstream viewing window position can continue to the downstream viewing window, thereby improving the windproof effect of the windproof part (flared edge) and reducing the amount of air entering the viewing window. Furthermore, since the values ​​of ΔH and ΔW are both less than or equal to 5mm, the obstruction range of the user's field of vision is small, which is beneficial to improving the user experience.

[0016] Optionally, the height dimension of the viewing window along the vertical direction of the side panel is H1, and the width dimension of the viewing window along the horizontal direction of the side panel is W1, wherein 15mm≤H1≤20mm and 5mm≤W1≤15mm. When H1 and W1 are within the above parameter range, it can ensure that the user can normally observe the cooking process of the food in the inner pot, while reducing the amount of airflow entering the viewing window.

[0017] Optionally, the inner pot has an air inlet on its side wall, with at least a portion of the air inlet located below the viewing window. This allows the airflow within the air guide cavity to flow downwards to the bottom position and then enter the inner pot through the air inlet, circulating the air and improving the cooking effect.

[0018] Optionally, there are multiple air inlets, which are arranged at intervals along the circumference of the inner pot. This allows for more uniform airflow into the bottom of the inner pot, which helps improve the uniformity of food heating and reduces obstruction to the circulating airflow, thus improving the airflow circulation efficiency.

[0019] Optionally, the height dimension of the air inlet along the vertical direction of the inner pot is H2, and the width dimension of the air inlet along the circumference direction of the inner pot is W2, wherein H2 ≤ W2. This allows for a more reasonable design of the air inlet shape, which is beneficial for increasing the air intake volume.

[0020] Optionally, the inner pot assembly further includes a frying basket disposed inside the inner pot, with the air inlet located on the lower side of the frying basket. Therefore, the airflow entering the inner pot from the air inlet can pass through the frying basket from bottom to top, thereby heating the back of the food and improving the uniformity of heating on both sides.

[0021] The air fryer of this utility model includes: a housing, wherein a heating chamber is provided inside the housing; and an inner pot assembly, wherein the inner pot assembly is the same as any one of the inner pot assemblies of this utility model, and the inner pot can be placed into the heating chamber and removed from the heating chamber.

[0022] According to the present invention, the air fryer, by arranging the viewing window and the viewing panel opposite each other, allows the user to observe the cooking of food in the inner pot through the viewing panel and the viewing window. When the circulating hot airflow enters the air guide cavity, since at least part of the wind baffle is located on the windward side of the viewing window and inside the air guide cavity, some of the airflow will impact the wind baffle to change the direction of airflow, thereby greatly reducing the amount of airflow entering the inner pot through the viewing window. This can reduce the airflow loss when the airflow passes through the air guide cavity, which is beneficial to improving the circulation effect of hot air. Attached Figure Description

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The following is a reference appendix. Figures 1 to 11 This invention describes an inner pot assembly and an air fryer according to embodiments of the present invention.

[0043] like Figures 1 to 6 As shown, the inner pot assembly of this utility model embodiment includes an inner pot 1 and a visible panel 2. The inner pot 1 has a side plate 11. The visible panel 2 is disposed outside the inner pot 1 and defines an air guide cavity 21 with the side plate 11. The side plate 11 is provided with a viewing window 111 and a windproof part 112. The viewing window 111 is arranged opposite to the visible panel 2. The outer edge of the viewing window 111 has a windward side 1111. At least a portion of the windproof part 112 is disposed on the windward side 1111 of the viewing window 111 and is located inside the air guide cavity 21.

[0044] According to the embodiment of the present invention, the inner pot assembly, by arranging the viewing window 111 opposite to the viewing panel 2, allows the user to observe the cooking process of the food in the inner pot 1 through the viewing panel 2 and the viewing window 111, thereby satisfying the user's need for visualization of food cooking. When the circulating hot airflow enters the air guide cavity 21, since at least a portion of the baffle 112 is located on the windward side 1111 of the viewing window 111 and within the air guide cavity 21, some of the airflow will impact the baffle 112 to change the direction of airflow, thus greatly reducing the amount of airflow entering the inner pot 1 through the viewing window 111. This reduces the airflow loss when the airflow passes through the air guide cavity 21, which is beneficial to improving the circulation effect of hot air.

[0045] It is understandable that the air guide cavity 21 constitutes part of the external circulation duct of the air fryer. In related technologies, because some airflow directly enters the inner pot 1 through the viewing window 111 when passing through the air guide cavity 21, some airflow cannot reach the bottom of the pot smoothly, resulting in heat loss in the external circulation duct. However, the inner pot assembly of this embodiment of the present invention, by setting a wind baffle 112, and at least part of the wind baffle 112 is located on the windward side 1111 of the viewing window 111, can block the airflow when it is about to enter the viewing window 111 and change its flow direction, thereby reducing the flow rate of airflow entering the inner pot 1 through the viewing window 111, so as to ensure the circulation effect of the external circulation duct of the air fryer.

[0046] In addition, compared with the solution of "installing a transparent plate at the position of the viewing window 111 for wind protection", the inner pot assembly of the present invention can reduce the number of parts of the inner pot assembly, which is conducive to improving assembly efficiency and reducing production costs.

[0047] It should be noted that the windward side 1111 of the viewing window 111 is the side of the outer edge of the viewing window 111 that is close to the upstream of the airflow, which can improve the windproof effect of the windproof part 112.

[0048] In one example, such as Figure 6 and Figure 11 As shown, the windward side 1111 includes a first windward side 11111, which is located above the viewing window 111. It can be understood that when the air fryer is working, most of the airflow will flow in the air guide cavity 21 in a downward direction. Therefore, by placing the wind deflector 112 on the first windward side 11111 (i.e., the wind deflector 112 is located above the viewing window 111), most of the airflow entering the viewing window 111 can be blocked, thereby reducing the flow of airflow entering the inner pot 1 through the viewing window 111.

[0049] For example, such as Figure 6 As shown, the first windward side 11111 extends horizontally, meaning the windbreak 112 is located directly above the viewing window 111. For example, as... Figure 11 As shown, the first windward side 11111 has a certain tilt angle, that is, the windproof part 112 is located at the upper angle of the viewing window 111. This utility model does not specifically limit the arrangement of the first windward side 11111.

[0050] In another example, such as Figure 6As shown, the windward side 1111 includes a second windward side 11112, which is located on one side of the viewing window 111 in the left-right direction. It can be understood that when the airflow moves within the air guide cavity 21, under the rotation of the fan 62, the airflow has a horizontal component while flowing downwards, meaning the airflow will flow downwards at an angle. Since the second windward side 11112 is located on one side of the viewing window 111 in the left-right direction, it can block the airflow that enters the viewing window 111 at an angle, further reducing the flow rate of airflow entering the inner pot 1 through the viewing window 111.

[0051] It should be noted that, as Figure 6 As shown, the second windward side 11112 is located on the side upstream of the airflow at the outer edge of the viewing window 111. For example, when the airflow flows downward at an angle from left to right, the second windward side 11112 is located on the left side of the viewing window 111. When the airflow flows downward at an angle from right to left, the second windward side 11112 is located on the right side of the viewing window 111.

[0052] Optionally, such as Figure 6 and Figure 11 As shown, the outer edge of the viewing window 111 also has a leeward side 1112. Along the airflow direction within the air guide cavity 21, the windward side 1111 is located upstream of the leeward side 1112. It can be understood that when the airflow passes through the air guide cavity 21, the airflow will first pass through the windward side 1111 of the viewing window 111 and then through the leeward side 1112 of the viewing window 111. The windbreak portion 112 includes a flange 1121. The first side of the flange 1121 is connected to the windward side 1111, and the second side of the flange 1121 extends obliquely toward the leeward side 1112. Since the first side of the flange 1121 is connected to the windward side 1111, and the second side of the flange 1121 extends obliquely toward the leeward side 1112, when the airflow passes through the flange 1121, it can change the direction of the airflow and make the airflow flow away from the viewing window 111, thereby reducing the amount of airflow entering the inner pot 1 through the viewing window 111. Furthermore, the flange 1121 has a simple structural design and is easy to process and manufacture.

[0053] In the examples of this utility model, such as Figure 6 As shown, both the first windward side 11111 and the second windward side 11112 are provided with flanges 1121, which can minimize the amount of airflow entering the viewing window 111.

[0054] Optionally, such as Figure 8As shown, the distance between the first side and the second side of the flange 1121 is L1, where 3mm ≤ L1 ≤ 6mm. For example, L1 can be 3mm, 4mm, 5mm, or 6mm. The inventors of this invention discovered through experimental research that when L1 adopts the above parameter range, it can reduce the flow rate of air entering the inner pot 1 through the viewing window 111, and also reduce the adverse effects on the airflow within the air guide cavity 21, thus ensuring the circulation effect of the air duct of the air fryer.

[0055] Optionally, such as Figure 8 As shown, the angle between the side of the flange 1121 along its thickness direction and the plane containing the viewing window 111 is α, where 15°≤α≤40°. For example, α can be 15°, 20°, 25°, 30°, 35°, or 40°. The inventors of this utility model discovered through experimental research that when α is too small (i.e., α is less than 15°), the airflow easily enters the inner pot 1 through the viewing window 111, and the wind-blocking effect is not obvious. When α is too large (i.e., α is greater than 40°), it will change the original airflow direction in the air guide cavity 21, thereby losing the original circulation effect of the external circulation duct.

[0056] Therefore, by designing α using the above parameters, the inner pot assembly of this utility model can reduce the flow rate of air entering the inner pot 1 through the viewing window 111, and also reduce the adverse effects on the airflow in the air guide cavity 21, thus ensuring the circulation effect of the air duct of the air fryer.

[0057] Optionally, such as Figure 5 and Figure 6 As shown, the angle between the side of the flange 1121 along its thickness direction and the plane containing the viewing window 111 is α, and the width of the air guide cavity 21 is K. K is positively correlated with α. It can be understood that when the width K of the air guide cavity 21 is larger, α also needs to be correspondingly larger; when the width K of the air guide cavity 21 is smaller, α also needs to be correspondingly smaller. This improves the wind-blocking effect of the flange 1121, reducing the amount of airflow entering the inner pot 1 through the viewing window 111, thus reducing airflow loss.

[0058] The distance between the first and second sides of the flange 1121 is L1, and the width of the air guide cavity 21 is K, with K being positively correlated with L1. When the width K of the air guide cavity 21 is designed to be larger, L1 also needs to be correspondingly larger; when the width K of the air guide cavity 21 is designed to be smaller, L1 also needs to be correspondingly smaller. This can improve the wind-blocking effect of the flange 1121, reducing the amount of airflow entering the inner pot 1 through the viewing window 111 and minimizing airflow loss.

[0059] It is understandable that the parameters of α and L1 can be complementary; that is, when one of α and L1 increases, the other can decrease. In other words, when designing the parameters of α and L1, they do not necessarily need to increase or decrease simultaneously.

[0060] The angle α of the flange 1121 is related to the angle of change in wind direction. The larger the angle α, the greater the angle of change in wind direction, the farther the wind is thrown outward, and the less likely the wind is to enter the viewing window 111. Conversely, the smaller the angle α of the flange 1121, the smaller the angle of change in wind direction, the closer the wind is thrown outward, and the easier it is for the wind to enter the viewing window 111. The longer the length L1 of the flange 1121, the stronger its wind-guiding effect. The longer the path the wind travels along the flange 1121, similar to an airplane runway. The longer the runway, the longer the time the aircraft spends on the runway, and the higher the speed and stability it achieves. Therefore, the less likely the wind is to change direction. So when the angle α of the flange 1121 is not large enough, the length L1 of the flange 1121 should be longer to compensate for the insufficient wind guidance caused by the insufficient angle α of the flange 1121.

[0061] In other words, the angle α and length L1 of the flange 1121 have a mutually compensating effect. However, both the angle α and the length L1 of the flange 1121 should be controlled within a certain range. If the angle α of the flange 1121 is too large, it will cause a significant change in wind direction, altering the original path of the wind. If it is too small, the guiding effect will be insufficient. The length L1 of the flange 1121 should also be controlled within a certain range. If the length of the flange 1121 is too long, it will obstruct the viewing window 111, affecting the user's viewing range. If the length of the flange 1121 is too short, the guiding effect on the wind will be insufficient.

[0062] The angle between one side of the flange 1121 along its thickness direction and the plane containing the viewing window 111 is α. The distance between the first side and the second side of the flange 1121 is L1. The cross-sectional area of ​​the viewing window 111 is Q. Both α and L1 are positively correlated with Q. That is to say, when the cross-sectional area Q of the viewing window 111 is designed to be large, both α and L1 need to be increased synchronously to ensure the wind-blocking effect of the flange 1121.

[0063] Optionally, such as Figure 6 and Figure 11 As shown, there are multiple viewing windows 111, which are spaced apart along the vertical direction and the horizontal direction of the side panel 11. The multiple viewing windows 111 are arranged in this way to increase the user's field of vision for the food in the inner pot 1, and to reduce the amount of airflow entering the viewing windows 111.

[0064] For example, the viewports 111 are arranged in a checkerboard pattern, and the cross-sectional outline of each viewport 111 is rectangular.

[0065] Optionally, such as Figure 6As shown, the distance between two adjacent viewing windows 111 along the vertical direction of the side panel 11 is ΔH, and the distance between two adjacent viewing windows 111 along the horizontal direction of the side panel 11 is ΔW, where 0 < ΔH ≤ 5mm and 0 < ΔW ≤ 5mm. That is, the distance between two adjacent viewing windows 111 should not be too large. When the values ​​of ΔH and ΔW are less than or equal to 5mm, the airflow guiding effect of the flange 1121 located at the upstream viewing window 111 can continue to the downstream viewing window 111, thereby improving the windproof effect of the windproof part 112 (flange 1121) and reducing the amount of air entering the viewing window 111. Furthermore, since the values ​​of ΔH and ΔW are both less than or equal to 5mm, the obstruction range of the user's field of vision is small, which is beneficial to improving the user experience.

[0066] For example, H1≥W1, thereby further reducing the amount of airflow entering the inner pot 1 through the viewing window 111.

[0067] like Figure 6 As shown, the height dimension of the viewing window 111 along the vertical direction of the side panel 11 is H1, and the width dimension of the viewing window 111 along the horizontal direction of the side panel 11 is W1, wherein 15mm≤H1≤20mm, 5mm≤W1≤15mm.

[0068] For example, H1 can be 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm, and W1 can be 5mm, 8mm, 10mm, 12mm, or 15mm. Through experimental research, the inventors of this invention discovered that when H1 and W1 are within the above parameter ranges, it ensures that the user can normally observe the cooking process of the food in the inner pot 1, while also reducing the amount of airflow entering the viewing window 111.

[0069] Optionally, such as Figure 3 , Figure 6 and Figure 7 As shown, the inner pot 1 has an air inlet 12 on its side wall, with at least a portion of the air inlet 12 located below the viewing window 111. Thus, when the airflow in the air guide cavity 21 moves downward to the bottom position, it can enter the inner pot 1 through the air inlet 12 to circulate the airflow and improve the cooking effect of the food.

[0070] like Figure 3 As shown, there are multiple air inlets 12, which are arranged at intervals along the circumference of the inner pot 1. This makes the airflow entering the bottom of the inner pot 1 more uniform, which is beneficial to improving the uniformity of food heating. It also reduces the obstruction to the circulating airflow, which is beneficial to improving the circulation efficiency of the airflow.

[0071] Optionally, such as Figure 6As shown, the height dimension of the air inlet 12 along the vertical direction of the inner pot 1 is H2, and the width dimension of the air inlet 12 along the circumference direction of the inner pot 1 is W2, where H2 ≤ W2. That is to say, the width dimension W2 of the air inlet 12 along the circumference direction of the inner pot 1 is greater than or equal to the height dimension H2 of the air inlet 12 along the vertical direction of the inner pot 1. This makes the shape design of the air inlet 12 more reasonable and helps to improve the air intake volume of the air inlet 12.

[0072] Optionally, the inner pot assembly also includes a frying basket 3, which is disposed inside the inner pot 1, and the air inlet 12 is located on the lower side of the frying basket 3. Therefore, the airflow entering the inner pot 1 from the air inlet 12 can pass through the frying basket 3 in a bottom-to-top direction, thereby heating the back of the food to improve the uniformity of heating on both sides of the food.

[0073] Optionally, such as Figures 2 to 4 As shown, the frying basket 3 is provided with multiple ventilation holes 31, which are arranged sequentially from the center to the edge of the frying basket 3, and are generally annular and arranged around the circumference of the frying basket 3. The multiple ventilation holes 31 are arranged in a sparse-inner-dense-outer-dense pattern, which facilitates more airflow from the edge of the frying basket 3 upwards, thereby helping to regulate the high airflow velocity and volume in the middle and low airflow velocity and volume on the outer side caused by the high negative pressure at the center of the fan 62, making the airflow velocity and volume more uniform throughout the inner pot 1, thus achieving a more even distribution of airflow. Figure 5 As shown, the center of the bottom of the inner pot 1 protrudes towards the frying basket 3 to further enhance the airflow guidance effect.

[0074] like Figure 1 As shown, the inner pot assembly also includes a handle 4, which is mounted on the visible panel 2 so that the user can pull out the inner pot assembly.

[0075] like Figure 5 As shown, the visible panel 2 includes a panel body 22 and a transparent plate 23. The panel body 22 is made of light-transmitting plastic, and the transparent plate 23 can be transparent glass. The transparent plate 23 is installed on the side of the panel body 22 near the inner pot 1 and is arranged opposite to and at intervals from the viewing window 111. The handle 4 is installed on the panel body 22.

[0076] like Figure 1 As shown, another embodiment of the air fryer of the present invention includes a housing 5 and an inner pot assembly. The inner pot assembly is the inner pot assembly of the present invention. The housing 5 is provided with a heating chamber 53. The inner pot 1 can be placed into the heating chamber 53 and can be removed from the heating chamber 53.

[0077] According to the embodiment of the present invention, the air fryer, by arranging the viewing window 111 and the viewing panel 2 opposite to each other, allows the user to observe the cooking of the food in the inner pot 1 through the viewing panel 2 and the viewing window 111. When the circulating hot airflow enters the air guide cavity 21, since at least part of the baffle 112 is located on the windward side 1111 of the viewing window 111 and is located in the air guide cavity 21, some of the airflow will impact the baffle 112 to change the flow direction of the airflow, thereby greatly reducing the amount of airflow entering the inner pot 1 through the viewing window 111. This can reduce the airflow loss when the airflow passes through the air guide cavity 21, which is beneficial to improving the circulation effect of hot air.

[0078] like Figure 1 As shown, the housing 5 includes an outer shell 51 and an inner shell 52. The inner shell 52 is located inside the outer shell 51 and forms a heating chamber 53. The inner pot 1 is located inside the heating chamber 53. The air fryer also includes a motor 61, a fan 62, and a heating element 65. The motor 61 and the fan 62 are both located inside the housing 5 and above the heating chamber 53. The motor 61 is connected to the fan 62 to drive the fan 62 to rotate. The heating element 65 is located below the fan 62 to evenly distribute the heat generated by the heating element 65 within the heating chamber 53.

[0079] like Figure 1 As shown, the air fryer also includes an air guide shroud 63 and a heat insulation shroud 64. The air guide shroud 63 is located above the heating chamber 53 and below the heating element 65. The heat insulation shroud 64 is located above the fan 62. An upper external circulation air duct is formed between the air guide shroud 63 and the heat insulation shroud 64. The outer peripheral wall of the inner pot 1, the inner wall of the inner shell 52, and the air guide chamber 21 together form a middle external circulation air duct. A lower external circulation air duct is formed between the bottom surface of the inner pot 1 and the bottom surface of the frying basket 3. The upper, middle, and lower external circulation air ducts are arranged sequentially from top to bottom and are interconnected. When the fan 62 rotates, the airflow flows sequentially in the upper, middle, and lower external circulation air ducts and enters the inner pot 1. Then it rises to the center of the fan 62 and is thrown out again by the rotation of the fan 62, thus realizing the circulation of hot air when the air fryer is working.
