Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and particularly relates to an air fryer. Background Art

[0002] An air fryer is a machine that can "fry" with air. It mainly uses air to replace the hot oil in the frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, making the ingredients almost fried. The working principle of the air fryer is "high-speed air circulation technology". It generates hot air by heating the heat pipe inside the machine at high temperature, and then uses a fan to blow the hot air into the pot to heat the food, so that the hot air circulates in a closed space, and uses the fat of the food itself to fry the food, thereby dehydrating the food and making the surface golden and crispy, achieving the effect of frying.

[0003] In existing air fryers, hot air is mainly concentrated above the baking tray, resulting in uneven heating of the upper and lower sides of the food. Users are often required to manually turn the food over, affecting the user experience. Utility Model Content

[0004] The utility model provides an air fryer, aiming to solve the problem of uneven heating of the upper and lower sides of food in the air fryer in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] Provided is an air fryer, comprising:

[0007] A pot body, a hot air assembly arranged above the pot body, and a container suspended in the pot body; a side air duct is formed between the outer edge of the container and the pot body, and a lower air duct is formed between the bottom surface of the container and the bottom surface of the pot body;

[0008] The ratio of the width of the side air duct to the width of the pot body is 0.05 to 0.15, and the ratio of the height of the lower air duct to the height of the pot body is 0.2 to 0.35.

[0009] In a possible implementation, the distance between the top edge of the container and the top of the pot body is defined as h1, the height of the pot body is defined as H, and the ratio of h1 to H is 0.6-0.8.

[0010] In a possible implementation, a plurality of guide ribs are provided on the bottom surface of the pot body, and the plurality of guide ribs are radially distributed about the center line of the pot body; and a ratio of a height of the guide ribs to a height of the pot body is 0.08 to 0.15.

[0011] In some embodiments, the ratio of the width of the guide rib to the width of the pot body is 0.06 to 0.12.

[0012] In some embodiments, a guide plate detachably connected to the pot body is provided at the bottom of the pot body, and each of the guide ribs is provided on the guide plate.

[0013] In some embodiments, the guide rib has two guide slopes that are symmetrically distributed about its long axis, and the distance between the two guide slopes gradually increases from top to bottom.

[0014] In a possible implementation, a support frame is provided on the periphery of the container, and the support frame includes a first frame body and a plurality of second frames, the first frame body is connected to the periphery of the container, the plurality of second frames are evenly distributed along the circumference of the first frame body, and the second frames are mounted on the pot body.

[0015] In some embodiments, the first frame is a frame continuously arranged along the circumference of the upper edge of the container, and the upper edge of the container is detachably overlapped with the first frame.

[0016] In some embodiments, the second frame extends in a direction perpendicular to the up-down direction, the side wall of the pot body is provided with overlapping ribs, and the outer edge of the second frame overlaps the overlapping ribs; or

[0017] The second frame extends in a direction perpendicular to the up-down direction, a slot is formed on the side wall of the pot body, and an outer edge of the second frame is locked in the slot.

[0018] In some embodiments, the second frame is a leg structure extending obliquely downward, and the bottom end of the second frame is supported at the intersection of the side wall of the pot body and the bottom surface of the pot body.

[0019] Compared with the prior art, the solution shown in the embodiment of the present application is that when the air fryer is working, the hot air generated by the hot air component will rotate and flow along the side wall of the pot body under the action of the wall attachment effect. When flowing through the side air duct openings around the container, due to the weakening of the gathering effect of the hot air by the wall attachment effect, part of the hot air will blow to the upper part of the container, while the other part of the hot air will continue to pass through the side air duct under the wall attachment effect to reach the lower air duct under the container. Reasonable setting of the width of the side air duct can ensure the amount of hot air entering the lower air duct. At the same time, since the height of the lower air duct will affect the hot air circulation under the container, by reasonably setting the width of the lower air duct, the hot air reaching the bottom of the container can transfer heat to the lower surface of the food in time. Under the condition of ensuring that the upper and lower surfaces of the container can obtain reasonable hot air distribution, the effect of uniform heating of the upper and lower surfaces of the food is achieved. The user does not need to manually turn the food over, the heating effect is good, and it is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0038] Please also read Figures 1 to 11The air fryer provided by the utility model is now described. The air fryer comprises a pot body 1, a hot air assembly 2 arranged above the pot body 1, and a container 3 suspended in the pot body 1; a side air duct 4 is formed between the outer edge of the container 3 and the pot body 1, and a lower air duct 5 is formed between the bottom surface of the container 3 and the bottom surface of the pot body 1; the ratio of the width of the side air duct 4 to the width of the pot body 1 is 0.05-0.15, and the ratio of the height of the lower air duct 5 to the height of the pot body 1 is 0.2-0.35. Among them, the width of the side air duct 4 is defined as d1, the width of the pot body 1 is defined as W, the height of the lower air duct 5 is defined as h2, and the height of the pot body 1 is defined as H, that is, the value of d1 / W is 0.05~0.15 (for example, 0.06, 0.07, 0.08, 0.09, 0.1, 0.11, 0.12, 0.13, 0.14), and the value of h2 / H is 0.2~0.35 (for example, 0.21, 0.23, 0.25, 0.27, 0.29, 0.30, 0.32, 0.33, 0.34).

[0039] In this embodiment, the container 3 can be a baking tray, a baking net, etc., and the container 3 is shown as a baking net by way of example in the figure. It should be noted that the bottom of the container 3 preferably has a ventilation opening, so that the hot air from the lower air duct 5 can be directly blown to the lower surface of the food, and the heating effect is better; of course, the bottom of the container 3 may not have a ventilation opening, and the hot air from the lower air duct 5 is blown to the lower surface of the container 3, and the food is indirectly heated by raising the temperature of the lower side wall of the container 3.

[0040] In this embodiment, the cross section of the pot body 1 can be rectangular, square, circular or other shapes, and the container 3 is generally arranged in accordance with the shape. Based on this, the width of the side air duct 4 is compared with the width of the pot body 1 to obtain the ratio, which means comparing the width of the side air duct 4 and the width of the pot body 1 measured in the same direction. For example, if the cross section of the pot body 1 is rectangular, the pot body 1 has a longer first width and a shorter second width on the cross section of the pot body 1. The first width is the width in the first direction, and the second width is the width in the second direction. When obtaining the ratio, it is necessary to compare the width value of the side air duct 4 in the first direction with the first width, and to compare the width value of the side air duct 4 in the second direction with the second width; the cross section of the pot body 1 is circular, and since the width of the side air duct 4 is consistent in the circumferential direction of the container 3, and the inner diameter of the pot body 1 is the same, the width of the side air duct 4 is compared with the inner diameter of the pot body 1; the way that the pot body 1 is square is also similar to the comparison principle, which will not be listed one by one here. This embodiment exemplarily shows an embodiment in which the pot body 1 is square.

[0041] Compared with the prior art, the air fryer provided in this embodiment has the following advantages: when the air fryer is working, the hot air generated by the hot air assembly 2 will rotate and flow along the side wall of the pot body 1 under the action of the wall attachment effect. When the hot air flows through the side air duct 4 around the container 3, due to the weakening of the gathering effect of the hot air by the wall attachment effect, part of the hot air will blow to the upper part of the container 3, while the other part of the hot air will continue to pass through the side air duct 4 under the action of the wall attachment effect to reach the lower air duct 5 below the container 3. The width of the side air duct 4 is reasonably set to ensure the amount of hot air entering the lower air duct 5. At the same time, since the height of the lower air duct 5 will affect the hot air circulation below the container 3, by reasonably setting the width of the lower air duct 5, the hot air reaching the lower part of the container 3 can transfer heat to the lower surface of the food in time. Under the condition of ensuring that the upper and lower parts of the container 3 can obtain reasonable hot air distribution, the upper and lower surfaces of the food can be evenly heated. The user does not need to turn the food over manually, the heating effect is good, and the use is more convenient.

[0042] The value of d / W is determined as follows:

[0043] Based on the premise that the value of d1 / W is 0.05-0.15, in order to ensure the use effect and space utilization, the pot body 1 with a small volume should take a smaller ratio (that is, the value of d1 / W is smaller). For example, for a 2L pot body 1, if the width of the pot body 1 is 160mm, the width of the side air duct 4 should be set to 8mm-12mm. This is because the wall attachment effect of the pot body 1 with a small volume is relatively stronger. When ensuring that more than half of the hot air passes through the side air duct 4, the smaller width of the side air duct 4 can improve the space utilization.

[0044] For a large-volume pot body 1, a larger ratio should be used (i.e., the value of d1 / W is larger). For example, for a 7L to 8L pot body 1, when the width of the pot body 1 is 250mm, the width of the side air duct 4 should be set to 25mm to 35mm. This is because the wall attachment effect will gradually weaken during the flow of hot air inside the large-volume pot body 1, and the hot air in the lower layer will disperse from the inner wall to the center of the pot body 1. Therefore, the side air duct 4 needs to have a larger width to ensure that more than half of the hot air passes through the side air duct 4, and at the same time, the side air duct 4 can gather the hot air for a second time.

[0045] The principle of determining the value of h2 / H is as follows:

[0046] The inventor found in the study of hot air circulation in the pot that the value of h2 / H needs to be greater than 0.2 to ensure that the hot air passes through the lower air duct 5, diffuses fully to the space below the container 3, and then smoothly turns to reach the lower surface of the food; if the value of h2 / H is too small (that is, the gap below the container 3 is too small), the wind pressure below the container 3 will increase, hindering the circulation of hot air. At the same time, considering the energy loss and space utilization, the gap space below the container 3 should not be too large. When the value of h2 / H is 0.35, the actual cooking effect of the upper and lower surfaces of the food is basically the same.

[0047] In some embodiments, see Figure 6 The distance between the top edge of the container 3 and the top of the pot body 1 is defined as h1, the height of the pot body 1 is defined as H, the ratio of h1 to H is 0.6~0.8, that is, the value of h1 / H is 0.6~0.8 (for example, 0.61, 0.63, 0.65, 0.69, 0.71, 0.73, 0.75, 0.77, 0.79).

[0048] Affected by the wall attachment effect, the height of the top edge of the container 3 from the top of the pot body 1 will affect the hot air distribution on the upper and lower surfaces, so it is necessary to set a suitable grill height. Based on this, the lower limit of the ratio is set to 0.6 to ensure that the hot air can smoothly enter the pot body 1 from the heating zone; if the ratio of h1 to H is too small, the hot air will stagnate in the heating zone. The upper limit of the ratio is set to 0.8 to ensure that when the wall attachment effect gradually weakens downward, more hot air can still pass through the side air duct 4 under the action of the wall attachment effect and then reach the bottom of the container 3.

[0049] In some embodiments, see Figures 1 to 6 and Fig.10 , the bottom surface of the pot body 1 is provided with a plurality of guide ribs 6, and the plurality of guide ribs 6 are radially distributed about the center line of the pot body 1. The guide ribs 6 can guide the hot air to turn, reduce the energy loss caused by the collision between the hot air blown downward by the side air duct 4 and the ground of the pot body 1, and are more conducive to the hot air to fully transfer energy to the lower surface of the food. Based on this, in order to optimize the diversion effect, the ratio of the height of the guide ribs 6 to the height of the pot body 1 is 0.08 to 0.15. The height of the guide ribs 6 is defined as h3, and the height of the pot body 1 is defined as H. The value of h3 / H is 0.08 to 0.15 (for example, 0.09, 0.1, 0.11, 012, 0.13, 0.14).

[0050] According to the shape of the pot body 1, the present embodiment exemplarily sets four guide ribs 6, each of which corresponds to a side edge of the pot body 1. Of course, the number of guide ribs 6 is not limited to four, and other numbers and distribution methods can also be used, and they are selectively set according to the shape of the pot body 1, which will not be listed here one by one.

[0051] On the basis of the above embodiment, in order to further optimize the guiding effect, the ratio of the width of the guiding rib 6 to the width of the pot body 1 is 0.06-0.12. The width of the guiding rib 6 is defined as d2, the width of the pot body 1 is defined as W, and the value of d2 / W is 0.06-0.12 (for example, 0.07, 0.8, 0.09, 01, 0.11).

[0052] In this embodiment, the width of the guide rib 6 remains consistent along its length direction.

[0053] In addition, the width of the pot body 1 refers to the width along any specified direction. For example, if the cross section of the pot body 1 is rectangular, the pot body 1 has a longer first width and a shorter second width on the cross section of the pot body 1. The first width is the width in the first direction, and the second width is the width in the second direction. When obtaining the ratio, it is necessary not only to compare the width value of the guide rib 6 with the first width, but also to compare the width value of the guide rib 6 with the second width. Both ratios need to meet the requirement of being within the range of 0.06 to 0.12. If the cross section of the pot body 1 is circular, the width of the guide rib 6 is compared with the inner diameter of the pot body 1; the way in which the pot body 1 is square is also a similar comparison principle, which will not be listed here one by one. This embodiment exemplarily shows an embodiment in which the pot body 1 is square.

[0054] More specifically, the guide ribs 6 may be Figure 3 See the structure shown. Figure 3 The guide rib 6 has two guide slopes 601 symmetrically distributed about its long axis, and the distance between the two guide slopes 601 gradually increases from top to bottom. The hot air blown downward from the side air duct 4 turns to the west in all directions after colliding with the bottom surface of the pot body 1. Since the guide ribs 6 are arranged radially, two adjacent guide ribs 6 can be enclosed with the side wall of the pot body 1 to form a guide space, so that the hot air gradually gathers to the center of the bottom surface of the pot body 1; at the same time, the guide slope 601 guides the hot air obliquely upward, so that the hot air is blown upward and smoothly to the lower surface of the food. The guide ribs 6 of this embodiment can effectively guide and turn the hot air to avoid energy loss to the greatest extent.

[0055] In this embodiment, the guide rib 6 can be a long strip extending along a straight path, or a curved strip extending along a curved path, and can be selectively arranged according to the guide effect. This embodiment exemplarily shows the arrangement of the guide rib 6 extending along a straight path, which is less difficult to design and manufacture, and can also better meet the guide requirements of the square pot body 1.

[0056] In some specific embodiments of the guide ribs 6, see Figures 1 to 6 The bottom of the pot body 1 is provided with a guide plate 7 detachably connected to the pot body 1, and each guide rib 6 is provided on the guide plate 7. The guide plate 7 is detachably connected to the pot body 1 by interference fitting, snap fitting, etc., and each guide rib 6 is integrally formed on the guide plate 7. When the pot body 1 needs to be cleaned, the guide plate 7 can be removed, and the pot body 1 and the guide plate 7 can be cleaned separately to ensure comprehensive cleaning. More specifically, the upper edge of the guide plate 7 is provided with a limiting flange 710, and the side wall of the pot body 1 is provided with a limiting convex rib 11 for supporting the limiting flange 710.

[0057] In other specific embodiments of the guide ribs 6, each guide rib 6 is integrally connected to the pot body 1, such as Fig.10 As shown, this arrangement is more suitable for the pot body 1 of the drawer-type air fryer. Among them, the implementation method of the integrated connection includes but is not limited to integrated welding, integrated stamping and the like.

[0058] See also Figure 2 , Figure 4 and Figure 5 In order to realize the overhead connection between the container 3 and the pot body 1, in some embodiments, a support frame 8 is provided on the periphery of the container 3, and the support frame 8 includes a first frame 810 and a plurality of second frames 820. The first frame 810 is connected to the periphery of the container 3, and the plurality of second frames 820 are evenly distributed along the circumference of the first frame 810, and the second frames 820 are mounted on the pot body 1. The even distribution of the second frames 820 makes the container 3 and the pot body 1 evenly stressed, which is conducive to smooth loading and unloading, and the position stability of the support frame 8 and the container 3 is relatively good after assembly.

[0059] In some embodiments, the first frame 810 is a frame continuously arranged along the circumference of the upper edge of the container 3, and the upper edge of the container 3 is integrally connected to the first frame 810, so that the container 3 and the support frame 8 are integrally arranged, and the integrity is stronger.

[0060] In some embodiments, the first frame 810 may be configured as follows: Figure 4 In the structure shown, the first frame 810 is a frame continuously arranged along the circumference of the upper edge of the container 3, and the upper edge of the container 3 is detachably overlapped on the first frame 810. This embodiment realizes the detachable connection between the container 3 and the support frame 8, and the type of the container 3 can be replaced according to different baking needs, such as a baking net, a bread pan, a baking tray, etc., which is more flexible in use.

[0061] Based on the above embodiment, in order to increase the reliability of the overlap fixation, an overlap flange is formed on the upper edge of the container 3, and the outer peripheral edge of the overlap flange forms a snap flange extending downward. After assembly, the overlap flange cooperates with the first frame 810 to achieve upper and lower limit, and the snap flange is snap-fitted with the first frame 810, thereby achieving limit in a direction perpendicular to the upper and lower directions, thereby ensuring the reliability of assembly. More specifically, the inner peripheral surface of the first frame 810 contacts the outer peripheral surface of the main body of the container 3, thereby enhancing the reliability of lateral limit.

[0062] In some embodiments where the second frame 820 is adapted to the pot body 1, see Figure 5 and Figure 7 The second frame 820 extends in a direction perpendicular to the up and down direction. The side wall of the pot body 1 is provided with overlapping convex ribs 9. The outer edge of the second frame 820 overlaps the overlapping convex ribs 9. The loading and unloading can be achieved directly by taking it up and putting it down, which is convenient to use.

[0063] Specifically, the second frame 820 is a C-shaped frame, and the two ends of the second frame 820 are respectively connected to the first frame 810. There is a large gap between each second frame 820 and the first frame 810 to prevent the second frame 820 from occupying too much of the side space of the container 3 and affecting the ventilation of the side air duct 4; at the same time, this structural design also enables the second frame 820 to have a certain elastic deformation ability in its own opening direction, which is convenient for abutting and limiting with the side wall of the pot body 1.

[0064] Furthermore, in order to simplify the structure of the second frame 820 and reduce the number of second frames 820, two second frames 820 are symmetrically provided, each second frame 820 is half-wrapped on one side of the first frame 810, and an inclined connecting section 821 is provided at the end of the second frame 820. Each second frame 820 can abut against the side wall of the pot body 1 in a direction perpendicular to its opening and in a direction parallel to its opening to limit its position.

[0065] In other embodiments where the second frame 820 is adapted to the pot body 1, see Figure 8 , the second frame 820 extends in a direction perpendicular to the up-down direction, a slot 10 is provided on the side wall of the pot body 1, and the outer edge of the second frame 820 is clamped in the slot 10. This embodiment realizes connection by clamping, and the upper limit effect in the up-down direction is better. The setting mode of the second frame 820 as a C-shaped frame is also suitable for this scenario, so as to avoid the second frame 820 from occupying too much lateral space of the container 3 and affecting the ventilation of the side air duct 4; at the same time, it also enables the second frame 820 to have a certain elastic deformation ability in its own opening direction, thereby improving the reliability of the clamping.

[0066] Furthermore, in order to simplify the structure of the second frame 820 and reduce the number of second frames 820, two second frames 820 are symmetrically provided, each second frame 820 is half-wrapped on one side of the first frame 810, and an inclined connecting section 821 is provided at the end of the second frame 820. Each second frame 820 can be engaged with the slot 10 of the side wall of the pot body 1 in a direction perpendicular to its opening and in a direction parallel to its opening.

[0067] In some other embodiments where the second frame 820 is adapted to the pot body 1, see Fig. 9, the second frame 820 is a leg structure extending obliquely downward, and the bottom end of the second frame 820 is supported at the intersection of the side wall of the pot body 1 and the bottom surface of the pot body 1. The second frame 820 adopts a leg design, which has a stronger load-bearing capacity, and the container 3 can hold heavier food. At the same time, the design of supporting the intersection of the side wall of the pot body 1 and the bottom surface of the pot body 1 also effectively limits the displacement of the support frame 8 in the direction perpendicular to the up and down direction, ensuring the horizontal position stability of the container 3. In addition, when taking and placing the container 3 and the support frame 8, since there is no restriction on the side wall of the pot body 1, it can be directly taken up and placed, and the taking and placing action is more convenient.

[0068] Based on the above embodiments, see Fig.10 By reasonably setting the length L and the inclination angle a of the legs, the height of the lower air duct 5 below the container 3 can be ensured to be reasonable, and the width of the side air duct 4 can also be ensured to be reasonable.

[0069] In other embodiments of the support frame 8, see Fig.11 The support frame 8 is a leg structure supported at the bottom of the container 3, and is directly fixedly connected to the bottom of the container 3 by welding or the like.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
