[0002] In the related art, the hot air assembly of the air fryer is usually arranged at the top of the shell. After the air fryer is used for a long time, oil stains are likely to deposit on the fan blades of the hot air assembly. In the high-temperature cooking process, the oil stains deposited on the fan blades are likely to fall onto the food being cooked, which can cause food contamination. In addition, since the hot air enters the cooking cavity from top to bottom, the upper and lower surfaces of the food are likely to be unevenly heated, resulting in poor cooking taste. SUMMARY

[0003] The utility model aims at at least one of the technical problems in the related art to some extent.

[0004] Therefore, the utility model provides an air fryer, the hot air assembly of which is not prone to depositing oil stains, and the food does not need to be turned over, so that the cooking effect is good.

[0005] The air fryer of the utility model comprises a shell, a cooking cavity is arranged in the shell, an inner pot can be put into and taken out of the cooking cavity, a hot air assembly is arranged in the shell and located at the side of the shell, an air inlet net is arranged in the shell and located between the inner pot and the hot air assembly, and a tray is arranged in the inner pot and divides the space of the inner pot into a storage area and a suspended area arranged in an upper and lower manner, and the storage area and the suspended area are both in communication with the air inlet net.

[0006] According to the air fryer of the utility model, the hot air assembly is arranged at the side of the shell, so that the hot air assembly can take in air from the side to reduce the probability of oil stains depositing on the hot air assembly, and the oil stains deposited on the hot air assembly will not fall downward into the cooking cavity. On the other hand, the tray divides the space of the inner pot into the storage area and the suspended area arranged in an upper and lower manner, and the storage area and the suspended area are both in communication with the air inlet net. Therefore, the hot air delivered by the air inlet net to the cooking cavity enters the suspended area and the storage area, so that the upper and lower surfaces of the food are evenly heated, the food does not need to be turned over during the cooking process, and the cooking effect is good.

[0007] Optionally, the air fryer further comprises a viewing window, which is installed on at least one of the top surface of the shell and the side surface of the shell.

[0037] 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.

[0038] The following is a reference appendix. Figures 1 to 12 An air fryer according to an embodiment of the present invention.

[0039] like Figures 1 to 5 As shown, the air fryer of this utility model embodiment includes: a housing 1, an inner pot 2, a hot air assembly 3, an air inlet mesh 4, and a tray 5. The housing 1 has a cooking chamber 11, and the inner pot 2 can be placed into and removed from the cooking chamber 11. The hot air assembly 3 is located inside the housing 1 and on its side, and can deliver hot air towards the cooking chamber 11. The air inlet mesh 4 is located inside the housing 1 and between the inner pot 2 and the hot air assembly 3. The tray 5 is located in the inner pot 2 and divides the space of the inner pot 2 into a storage area 27 and a suspended area 28 arranged vertically. Both the storage area 27 and the suspended area 28 are connected to the air inlet mesh 4.

[0040] Understandably, the area above the tray 5 constitutes storage area 27, and the side opening of storage area 27 is opposite to and connected to air inlet mesh 4. The area below the tray 5 constitutes suspended area 28, and the side opening of suspended area 28 is opposite to and connected to air inlet mesh 4.

[0041] According to the embodiment of the present invention, the air fryer has a hot air assembly 3 arranged on the side of the casing 1, allowing for lateral air intake. This reduces the probability of oil stains depositing on the hot air assembly 3 and prevents oil stains deposited on it from falling into the cooking chamber 11. Furthermore, the tray 5 divides the space of the inner pot 2 into a storage area 27 and a suspended area 28 arranged vertically, both connected to the air intake mesh 4. Therefore, a portion of the hot air supplied to the cooking chamber 11 by the air intake mesh 4 enters the suspended area 28, while the remaining portion enters the storage area 27, ensuring even heating of both sides of the food. This eliminates the need for flipping during cooking, resulting in better cooking performance. In other words, the hot air assembly 3 can simultaneously circulate hot air to both the storage area 27 and the suspended area 28, improving the uniformity of heating of the food on the tray 5.

[0042] likeFigure 2 and Figure 5 As shown in

[0043] In the example of the utility model, as Figure 2 and Figure 5 As shown in

[0044] Optionally, as Figure 1 and Figure 2 As shown in

[0045] For example, the visible window 6 is installed on the top surface of the cabinet 1. For another example, the visible window 6 is installed on the left side surface, the right side surface or the front side surface of the cabinet 1.

[0046] The material of the visible window 6 can be glass material, so as to facilitate daily cleaning of the user.

[0047] In the example of the utility model, the visible window 6 is fixedly connected with the cabinet 1. In other words, the visible window 6 is a non-moving component, so as to improve the overall sealing performance of the cabinet 1, reduce the probability of heat leakage from the gap between the visible window 6 and the cabinet 1, improve the working efficiency of the air fryer and reduce the energy consumption of the air fryer.

[0048] Optionally, as Figure 2 , Figure 8 and Figure 9As shown in the drawings, the inner pot 2 comprises a front wall plate 21, a bottom plate 22 and two side plates 23, the front wall plate 21 is installed on the front side of the bottom plate 22, and the two side plates 23 are respectively installed on the left and right sides of the bottom plate 22, one side of the side plate 23 is provided with a stop rib 231 extending along the front-rear direction of the shell 1, and the tray 5 is slidingly supported on the upper side of the stop rib 231. It can be understood that the front wall plate 21 is used to cover the open port 13 of the shell 1, one side plate 23 is installed on the left side of the front wall plate 21, and the other side plate 23 is installed on the right side of the front wall plate 21. The stop rib 231 is arranged on the inner side of the side plate 23, and the two stop ribs 231 on the two side plates 23 are located at the same horizontal height.

[0049] When installing the tray 5, the user can place the tray 5 in the inner pot 2 along the direction from top to bottom, and the left and right sides of the tray 5 are respectively supported on the left and right stop ribs 231. Alternatively, the user can also slide the tray 5 into the inner pot 2 along the direction from back to front, and the two stop ribs 231 can guide the sliding of the tray 5.

[0050] The air fryer of the embodiment of the utility model can make the installation and removal of the tray 5 simple by setting the inner pot 2 to the above structure. In addition, the side plate 23 can avoid the direct contact of the food with the inner wall of the shell 1, so as to facilitate the daily cleaning of the user, and the side plate 23 has a certain heat insulation effect, which is helpful to reduce the temperature of the outer wall of the shell 1.

[0051] For example, as shown in the drawings, Figure 7 and Figure 9 The stop rib 231 can be formed on the side plate 23 in a punching manner, so as to facilitate the processing and manufacturing of the inner pot 2.

[0052] Further, as shown in the drawings, Figure 2 , Figure 8 and Figure 9 The inner pot 2 further comprises a handle 24 and a heat preservation plate 25, the heat preservation plate 25 is arranged on the front side of the front wall plate 21, and the handle 24 is connected with the heat preservation plate 25. The air fryer of the embodiment of the utility model can reduce the temperature of the front wall plate 21 transmitted to the handle 24 by arranging the heat preservation plate 25 between the handle 24 and the front wall plate 21, so as to prevent the user from being scalded and improve the use experience of the user.

[0053] For example, the threaded parts are sequentially arranged in the handle 24, the heat preservation plate 25 and the front wall plate 21, so as to fix the handle 24, the heat preservation plate 25 and the front wall plate 21.

[0054] Optionally, as shown in the drawings, Figure 8 and Figure 9As shown, the inner pot 2 includes a front wall plate 21, a bottom plate 22 and a first baffle 26, the front wall plate 21 is installed on the front side of the bottom plate 22, and the first baffle 26 is arranged on the rear side of the bottom plate 22 and opposite to the air inlet net 4. It can be understood that the left and right ends of the first baffle 26 are connected with the two side plates 23 respectively, and the left and right ends of the front wall plate 21 are connected with the two side plates 23 respectively, so as to form a box-shaped structure with an upward opening. The first baffle 26 is located at the windward opening of the floating area 28, in other words, the first baffle 26 is arranged adjacent to the air inlet net 4. The air fryer of the embodiment of the utility model can store the oil stains dropped by the cooking food in the floating area 28 by arranging the first baffle 26, so as to avoid the problem of oil stains overflowing from the bottom of the inner pot 2, and facilitate the daily cleaning of the user.

[0055] On the other hand, since the side of the tray 5 adjacent to the air inlet net 4 (i.e. the second baffle 52) will block a part of the airflow from flowing into the storage area 27, the first baffle 26 can also block a part of the airflow from entering into the floating area 28, and form a wind blocking structure, so that the airflow resistance entering into the storage area 27 and the airflow resistance entering into the floating area 28 are substantially equal, so as to balance the air pressure in the cooking cavity 11, and reduce the problems of noise, vibration or deformation caused by the unbalanced air duct resistance when the hot air assembly 3 is blowing.

[0056] Further, as shown in the drawings, Figure 8 The height of the first baffle 26 is H1, and the hot air assembly 3 has a fan 33, and the diameter of the fan 33 is D, wherein D / 64≤H1≤D / 8. In other words, H1 is selected from 0.0156D to 0.125D.

[0057] For example, H1 can be 0.0156, 0.02, 0.04, 0.06, 0.08, 0.1, 0.125.

[0058] The inventors of the utility model have found through experimental research that when H1 is less than D / 64, the problem of food oil produced in the process of cooking food in the air fryer overflowing the first baffle 26 may occur, and the airflow resistance received by the tray 5 cannot be balanced, which leads to the problems of noise, vibration or deformation easily occurring in the working process of the air fryer. In addition, when H1 is less than D / 64, the speed of the fan 33 matched with the air fryer needs to be correspondingly lowered, which leads to the difficulty in selecting the driving motor 32 and the high cost.

[0059] When H1 is greater than D / 8, the circulating hot airflow entering into the floating area 28 will be greatly hindered, which leads to the poor hot air circulation effect in the cooking cavity 11, so that the back of the food cannot be uniformly heated, that is, the air fryer cannot realize the function of free turning. In addition, when H1 is greater than D / 8, the speed of the fan 33 matched with the air fryer needs to be correspondingly increased, which leads to the difficulty in selecting the driving motor 32 and the high cost.

[0060] Therefore, the air fryer of the embodiment of the present application can stop the oil dropped by the cooking food in the suspended area 28, so as to facilitate the cleaning and maintenance of the air fryer in the later period.

[0061] On the other hand, since the tray 5 is adjacent to one side of the air inlet net 4, it will block a part of the airflow from flowing into the storage area 27, and the first baffle 26 can also block a part of the airflow from entering the suspended area 28, and form a wind blocking structure, thereby balancing the air pressure in the cooking cavity 11, so as to reduce the noise, vibration or deformation problems caused by the unbalanced air duct resistance when the hot air assembly 3 discharges air.

[0062] In addition, the up-down circulation effect of the hot air in the cooking cavity 11 can be ensured, which is beneficial to improve the uniformity of food heating.

[0063] In addition, most of the driving motors 32 can meet the selection requirements, which is beneficial to reduce the production cost of the air fryer.

[0064] For example, the height difference between the tray 55 and the bottom plate 2222 is H0, H0 is generally D / 4, and the height of the first baffle 2626 is H1, wherein H1 is equal to H0 / 2, that is, H1 is equal to D / 8.

[0065] Optionally, as shown in Figure 8 and Figure 9 The tray 5 includes a tray body 51 and a second baffle 52, the second baffle 52 is arranged on the rear side of the tray body 51 and opposite to the air inlet net 4, and the second baffle 52 extends upward. It can be understood that the tray body 51 and the second baffle 52 generally form an L-shaped plate structure. The second baffle 52 is located at the windward opening of the storage area 27, in other words, the second baffle 52 is arranged adjacent to the air inlet net 4. The air fryer of the embodiment of the present application can prevent the food in the tray 5 from being directly blown by high-temperature air and prevent the food from being scorched, and can also ensure the circulation effect of the hot air, which is beneficial to the uniform heating of the food.

[0066] Further, as shown in Figure 8 The second baffle 52 extends upward by a height H2, and the hot air assembly 3 has a fan 33, and the diameter of the fan 33 is D, wherein D / 64≤H2≤D / 8.

[0067] In other words, H2 is selected from 0.0156D to 0.125D.

[0068] For example, H2 can be 0.0156, 0.02, 0.04, 0.06, 0.08, 0.1, 0.125.

[0069] The inventor of the present utility model found through experimental research that when H2 is less than D / 64, the food near the position of the air inlet net 4 will be burned by high temperature, that is, the food in the tray 5 is easily directly blown and scorched by the high-temperature hot air. At this time, the effect of the second baffle 52 in blocking the high-temperature hot air is poor. And it is impossible to balance the air flow resistance received by the first baffle 26, resulting in problems such as noise, vibration or deformation during the operation of the air fryer.

[0070] When H2 is greater than D / 8, the hot air circulation effect in the cooking cavity 11 will be poor, which is not conducive to the uniform heating of food and the cooking efficiency is low.

[0071] Therefore, when the air fryer of the embodiment of the present utility model sets H2 within the above range: on the one hand, it can prevent the food in the tray 5 from being easily directly blown and scorched by the high-temperature hot air.

[0072] On the other hand, it can balance the air flow resistance received by the first baffle 26 and avoid problems such as noise, vibration or deformation during the operation of the air fryer.

[0073] On the other hand, it is beneficial to ensure the hot air circulation effect in the cooking cavity 11, improve the cooking efficiency of food, and the food is heated more evenly.

[0074] On the further hand, it can make most of the drive motors 32 meet the selection requirements, which is beneficial to reducing the production cost of the air fryer.

[0075] Exemplarily, as Figure 8 shown, the height of the front wall plate 21 of the inner pot 2 is generally equal to the height of the fan 33, that is, the height of the front wall plate 21 of the inner pot 2 is D. The height difference between the tray 5 and the bottom plate 22 is H0, and H0 is generally D / 4. Among them, the height of the first baffle 26 is generally D / 8, and the height from the upper end of the first baffle 26 to the bottom surface of the tray 5 is generally D / 8. The height of the second baffle 52 is generally D / 8, and the height from the upper end of the second baffle 52 to the middle position of the front wall plate 21 is generally D / 8.

[0076] The inventor found through experimental test data and numerical simulation methods that the designed height of H2 has a functional relationship with the rotational speed n of the drive motor 32, the power P of the heating element 34, and the air permeability area A of the air inlet net 4. Through fitting analysis of the experimental data, it is obtained that: H2 = D / 8 - K / (n·P·A). In the above formula, all values are absolute values, and the value of H2 cannot be negative.

[0077] In the formula, D is the diameter of the fan 33, m; K is the unit conversion coefficient, 0 < K < 5000 (for example, K is 2000); n is the rotational speed of the drive motor 32, r / min; P is the power of the heating element 34, W; A is the area of the air inlet net 4, m 2 .

[0078] It can be understood that the parameters of D, n, P, and A can take one of them as an independent variable and H2 as a dependent variable to match the parameters with each other. In other words, the parameter design of H2 is related to the parameters of D, n, P, and A.

[0079] When H2 is in the numerical range of D / 64≤H2≤D / 8, the parameters of D, n, P, and A also need to be considered. Alternatively, after obtaining the parameters of D, n, P, and A, the design parameter of H2 can also be obtained according to the above formula. Similarly, when four of the parameters of H2, D, n, P, and A are determined, the other parameter can be obtained according to the above formula.

[0080] The inventors of the present application found through experimental research that when the above parameters (H2, D, n, P, and A) of the air fryer satisfy the above formula, the heat circulation efficiency of the air fryer is relatively high, the food cooking effect is relatively good, and the energy consumption is relatively low

[0081] For example, the inventors of the present application take the fan power P, the rotational speed n, the air permeation area A, and the diameter D of the fan 33 as independent variables, and the design height H2 obtained through experiments is as follows:

[0082] The inventors of the present application take the fan power P as an independent variable, and the design height H2 obtained through experiments is as follows:

[0083] Table 1 Experimental test data (when the fan power changes) H2 design height

[0084]

[0085] The inventors of the present application take the rotational speed n as an independent variable, and the design height H2 obtained through experiments is as follows:

[0086] Table 2 Experimental test data (when the fan rotational speed changes) H2 design height

[0087]

[0088] The inventors of the present application take the air permeation area A as an independent variable, and the design height H2 obtained through experiments is as follows:

[0089] Table 3 Experimental test data (when the air permeation area A changes) H2 design height

[0090]

[0091] The inventors of the present application take the diameter D of the fan 33 as an independent variable, and the design height H2 obtained through experiments is as follows:

[0092] Table 4 Experimental test data - (when the diameter D of the fan 33 changes) design height of H2

[0093]

[0094] It can be understood that the inventor of the present application found through experimental research that when the rotational speed of the driving motor 32 is higher n, or the power of the heating element 34 is higher P, or the air permeability area A of the air inlet net 4 is larger, the height and thickness of the blocking structure (i.e. the second baffle 52) on the side of the tray 5 facing the hot air need to be increased, and the design height of H2 satisfies the following functional relationship: H2=D / 8-K / (n·P·A)

[0095] In some embodiments, as shown in Figure 6 and Figure 9 , the tray 5 is provided with first air holes 53 and second air holes 54, the first air holes 53 and the second air holes 54 are both multiple and are arranged in a circumferential direction of the tray 5, and the first air holes 53 are arranged outside the second air holes 54. It can be understood that the multiple air holes form an annular ring, the second air holes 54 are arranged inside the annular ring, and the multiple second air holes 54 are arranged in a circumferential direction of the annular ring.

[0096] The air fryer of the embodiment of the present application can make the hot air flow in the up-down direction by arranging the first air holes 53 and the second air holes 54 on the tray 5, so as to improve the uniformity of the heating of the upper and lower surfaces of the food. Since the first air holes 53 and the second air holes 54 are both multiple and are arranged in a circumferential direction of the tray 5, and the first air holes 53 are arranged outside the second air holes 54, the food adjacent to the center of the tray 5 and the food adjacent to the edge of the tray 5 can be heated at the same time, so as to improve the uniformity of the heating of the food at different positions on the tray 5.
