[0004] But vertical hole has large air resistance to air flow, and does not have flow guiding effect, which leads to the technical problem that the heating effect of hot air circulation air flow on food is poor. UTILITY MODEL CONTENTS

[0005] The utility model aims at at least one of the technical problems existing in prior art.

[0006] Therefore, the utility model provides a kind of cooking equipment.

[0007] Therefore, the utility model provides a kind of cooking equipment.

[0008] In the technical scheme, a kind of cooking equipment is limited, and the skin of food can be rapidly heated by high-temperature air flow, so that the food with crisp and crisp outer skin and attractive appearance is obtained.

[0009] The cooking equipment includes body, fan blade and cover body, the body is the main structure of the cooking equipment, the body forms the outer surface of the cooking equipment, and the body is enclosed to form a cooking cavity, and the food is cooked in the cooking cavity.

[0010] The fan blade is arranged on the body, and the fan blade can rotate on the body. The rotating fan blade can disturb the air in the body, and the heating component can blow directional high-temperature air flow into the cooking cavity, so that the skin of the food is rapidly heated by the high-temperature air flow.

[0011] The fan blade includes an air outlet side and an air return side, the air outlet side is located at the circumferential side of the fan blade, and the air return side is located at the side of the fan blade facing the cooking cavity. The directional high-temperature airflow includes an air outlet airflow and an air return airflow, when the fan blade rotates, the air outlet airflow first spreads in all directions, then flows from top to bottom along the side wall of the cooking cavity after contacting the side wall of the cooking cavity, and then converges to the central area of the cooking cavity, and forms the air return airflow flowing to the fan blade after heating the food.

[0012] The cover body is arranged outside the fan blade, and the cover body is provided with an air outlet and an air return, the air outlet is located at the air outlet side of the fan blade, and the air return is located at the air return side of the fan blade, the air outlet airflow needs to pass through the air outlet to the outside of the cover body, and correspondingly, the air return airflow needs to enter the cover body from the air return. The cover body can play a protective role outside the fan blade, on the one hand, to avoid the rotating fan blade contacting the food, and on the other hand, to avoid the user being scratched by the fan blade when accessing the food or cleaning the cooking cavity. The cover body can also play a role in blocking grease outside the fan blade, thereby improving the cleanliness of the fan blade and prolonging the cleaning cycle of the fan blade.

[0013] On this basis, the size of the air outlet in the circumferential direction of the fan blade is the width of the air outlet, and the size of the air outlet in the axial direction of the fan blade is the height of the air outlet, wherein the width of the air outlet is greater than the height of the air outlet.

[0014] Compared with the longitudinal opening in the related art, the transverse air outlet in the present application is more suitable for the flow direction of the air outlet airflow at the circumferential side of the fan blade, thereby reducing the wind resistance of the air outlet to the air outlet airflow and increasing the flow rate of the air outlet airflow. Moreover, the transverse air outlet can guide the air outlet airflow, thereby optimizing the wind field characteristics in the cooking cavity and further increasing the flow rate of the high-temperature airflow in the cooking cavity.

[0015] As can be seen, the technical scheme can improve the heating rate and heating uniformity of the food in the cooking cavity by setting the air outlet with a width greater than a height, thereby solving the technical problem of poor food heating effect caused by large wind resistance of the safety cover and the safety cover not having a flow guiding function in the related art, and further achieving the technical effects of improving the quality of cooked food and improving the practicality of the cooking equipment.

[0016] Specifically, in the technical scheme, the air outlet can be a vertically arranged strip hole, or a special-shaped hole such as an oval hole or a rhombic hole. In this regard, the technical scheme does not rigidly limit the shape of the air outlet, and only needs to meet the size requirement that the width is greater than the height.

[0017] In addition, the above-mentioned cooking equipment provided by the utility model can also have the following additional technical features:

[0018] In some technical solutions of the utility model, optionally, the air outlet is strip-shaped, and an included angle between a tangential direction of the air outlet and an axial direction of the fan blade ranges from greater than 45 degrees to less than or equal to 90 degrees.

[0019] In the technical solution, the included angle between the tangential direction of the strip-shaped air outlet and the axial direction of the fan blade needs to be greater than 45 degrees and less than or equal to 90 degrees.

[0020] By limiting the above-mentioned included angle range, it can be ensured that the size of the strip-shaped air outlet in the circumferential direction is greater than the size in the axial direction, so as to reduce the wind resistance of the air outlet to the air flow and improve the flow guiding effect of the air outlet on the air flow.

[0021] Specifically, the included angle between the length direction of the air outlet and the axial direction of the fan blade can be adjusted according to the shape of the blade on the fan blade, the orientation of the blade and the number of the blade, so as to further reduce the wind resistance and improve the flow guiding effect.

[0022] In some technical solutions of the utility model, optionally, the tangential direction of the air outlet is perpendicular to the axial direction of the fan blade.

[0023] In the technical solution, the tangential direction of the air outlet is perpendicular to the axial direction of the fan blade, that is, the air outlet extends in the circumferential direction of the fan blade.

[0024] By setting the transverse air outlet with the tangential direction perpendicular to the axial direction of the fan blade, the shape of the air outlet can be adapted to the centrifugal fan wheel, on the one hand, the flow rate of the air flow diffused around the fan wheel is improved by reducing the wind resistance, and on the other hand, the wind field characteristics in the cooking cavity are optimized by enhancing the guiding effect on the air flow, the probability of turbulence and chaotic flow in the cooking cavity is reduced, and the technical effects of improving the cooking effect of the cooking equipment and improving the practicability of the cooking equipment are realized.

[0025] In some technical solutions of the utility model, optionally, the cover body comprises an air outlet array, the air outlet array comprises a plurality of air outlets, and the plurality of air outlets in the same air outlet array are uniformly distributed in the circumferential direction of the fan blade.

[0026] In the technical solution, the plurality of air outlets form an air outlet array, the cover body is provided with at least one air outlet array, the plurality of air outlets belonging to the same air outlet array are spaced apart in the circumferential direction of the fan blade, and the plurality of air outlets are uniformly distributed around the fan blade, that is, the included angle between the adjacent two air outlets is equal.

[0027] By setting the air outlet array composed of a plurality of air outlets, the air outlets can cover multiple angles around the fan blade, so that the air flow blown out by the fan blade can be diffused in multiple directions into the cooking cavity, thereby improving the heating uniformity of the food and improving the quality of the food.

[0028] By uniformly distributing the plurality of air outlets in the air outlet array around the fan blade, the uniformity of the air outlet of the cover body can be further improved, thereby optimizing the wind field characteristics in the cooking cavity, improving the heating uniformity of the high-temperature airflow on the food, and reducing the probability of turbulence and chaotic flow in the cooking cavity.

[0029] In some technical solutions of the present application, the number of air outlet arrays is multiple; the plurality of air outlet arrays are distributed in the axial direction of the fan blade; the air outlets on the two adjacent air outlet arrays are arranged in a staggered manner in the tangential direction of the fan blade.

[0030] In this technical solution, the cover body is provided with a plurality of air outlet arrays, and the plurality of air outlet arrays are arranged at intervals in the circumferential direction of the fan blade.

[0031] For example, the cover body includes three air outlet arrays, one of which is located at the middle segment of the cover body, and the other two are located on the upper and lower sides.

[0032] By increasing the number of air outlet arrays, the area covered by the air outlets can be expanded, on the one hand, reducing the probability of dead angles on the cover body, and on the other hand, reducing the resistance of the cover body to the airflow, thereby improving the heating rate of the food by increasing the flow rate of the airflow, and improving the quality of the food.

[0033] In this technical solution, in the case where the cover body is provided with a plurality of air outlet arrays in the axial direction of the fan blade, the air outlets of the two adjacent air outlet arrays in the axial direction of the fan blade are arranged in a staggered manner, that is, the two adjacent air outlet arrays have a deflection angle in the circumferential direction of the fan blade.

[0034] Specifically, the deflection angle can be designed according to the size of the air outlet, the number of air outlets in the air outlet array, and the number of air outlet arrays, which is not limited in this technical solution as long as it meets the staggered arrangement requirement.

[0035] By arranging the two adjacent air outlet arrays in a staggered manner, the air resistance of the air outlet to the airflow can be further reduced, thereby improving the air outlet speed of the cover body to improve the heating efficiency of the food. At the same time, arranging the two adjacent air outlet arrays in a staggered manner can also reduce the probability of turbulence and chaotic flow in the cooking cavity, thereby improving the heating uniformity of the food and improving the quality of the cooked food.

[0036] In some technical solutions of the present application, the cover body includes: a bottom plate, the bottom plate is arranged on the side of the fan blade facing the cooking cavity, and the center of the bottom plate includes an air return port; a side plate, the side plate is connected with the bottom plate, the side plate surrounds the bottom plate, and the air outlet is located on the side plate.

[0037] In this technical solution, the cover body includes a bottom plate and a side plate, the side plate is connected with the edge of the bottom plate, and the side plate surrounds the four sides of the bottom plate. After assembly, the bottom plate is located on the side of the fan blade facing the cooking cavity, and the side plate is located on the circumferential side of the fan blade.

[0038] The outlet is arranged on the side plate, the return air inlet is arranged on the bottom plate, the directional flow of the high-temperature air flow includes the outlet air flow and the return air flow, when the fan blade rotates, the outlet air flow first diffuses to the surroundings, contacts the side wall of the cooking cavity through the outlet after passing through the side plate, and flows from top to bottom under the guidance of the side wall of the cooking cavity, and then the air flow converges to the central area of the cooking cavity, and forms the return air flow flowing to the fan blade after heating the food, and the return air flow enters the inside of the cover through the return air inlet to participate in the next heating cycle of the high-temperature air flow.

[0039] The side plate and the bottom plate can play a protective role on the outer side of the fan blade, on the one hand, the rotating fan blade can be prevented from contacting the food, and on the other hand, the user can be prevented from being scratched by the fan blade when accessing the food or cleaning the cooking cavity. The cover can also play a role in blocking grease on the outer side of the fan blade, thereby improving the cleanliness of the fan blade and prolonging the cleaning cycle of the fan blade.

[0040] Specifically, the return air inlet is arranged at the center of the bottom plate, and by arranging the return air inlet at the central area of the bottom plate, the cross-sectional area of the return air path can be increased, thereby improving the air flow circulation efficiency in the cooking equipment and optimizing the heating effect of the cooking equipment on the food.

[0041] In some technical solutions of the utility model, optionally, the fan blade has magnetic conductivity, and the cooking equipment comprises an electromagnetic disc, and the electromagnetic disc is arranged opposite to the fan blade.

[0042] In the technical solution, the fan blade is prepared by using a material with magnetic conductivity, and specifically, the fan blade can be prepared by using a metal material.

[0043] On this basis, the cooking equipment further comprises an electromagnetic disc, and the electromagnetic disc is arranged on the body and arranged opposite to the fan blade with magnetic conductivity.

[0044] After being powered on, the electromagnetic disc can generate an electromagnetic field in the area where the fan blade is located, the fan blade with magnetic conductivity is heated under the action of the electromagnetic field, and the high-temperature fan blade not only forms a directional flow of air during rotation, but also heats the air flow to increase the temperature of the air flow, thereby achieving the technical effect of improving the heating efficiency of the cooking equipment. Moreover, compared with the heat pipe in the heat radiation heating scheme, the heat generated by the electromagnetic disc itself is relatively small, which is conducive to reducing the surface temperature of the cooking equipment, thereby reducing the probability of scalding the user, and further improving the safety of the cooking equipment.

[0045] On this basis, in the case that the fan blade has a heating function, the heating efficiency of the fan blade on the air flow can be improved by increasing the size of the fan blade. In this regard, the outlet arranged transversely can improve the flow efficiency of the air flow on the basis that the fan blade has a heating function, so as to further improve the heating efficiency of the cooking equipment.

[0046] Optionally, the cover body has magnetic conductivity, and the cooking device comprises an electromagnetic disc, and the electromagnetic disc is arranged opposite to the cover body.

[0047] In the technical scheme, the cover body is prepared by using a material with magnetic conductivity, and specifically, a metal material can be selected to prepare the cover body.

[0048] On this basis, the cooking device further comprises an electromagnetic disc, the electromagnetic disc is arranged on the body, and the electromagnetic disc and the cover body with magnetic conductivity are arranged opposite to each other.

[0049] After being powered on, the electromagnetic disc can generate an electromagnetic field in the area where the cover body is located, and the cover body with magnetic conductivity is heated under the action of the electromagnetic field, so that the high-temperature cover body can not only protect the fan blades but also heat the airflow to improve the temperature of the airflow, thereby achieving the technical effect of improving the heating efficiency of the cooking device. Moreover, compared with the heat pipe in the heat radiation heating scheme, the heat generated by the electromagnetic disc itself is relatively small, which is conducive to reducing the temperature of the outer surface of the cooking device, thereby reducing the probability of scalding of the user and improving the safety of the cooking device.

[0052] By arranging the cover body that can rotate with the fan blades, the airflow can be uniformly blown out of the cover body through the multiple air outlets distributed circumferentially on the cover body, so that the high-temperature airflow flowing in a certain direction is not blocked by the area of the cover body where no air outlet is arranged for a long time, thereby achieving the technical effect of improving the heating uniformity of the cooking device.

[0053] In some technical schemes of the utility model, the cooking device further comprises a flow guide plate, the flow guide plate is arranged on the circumferential side of the cover body, and the flow guide plate is used for guiding the airflow to flow to the circumferential side of the cover body.

DETAILED DESCRIPTION

[0065] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0067] The following will be described with reference to Figures 1 to 6 A cooking device according to some embodiments of the present application.

[0068] As Figure 1 , Figure 2 and Figure 3As shown in the utility model one embodiment proposes a kind of cooking equipment 100, and the cooking equipment 100 includes: body 110, and body 110 includes cooking cavity 1102 inside;Fan blade 120, fan blade 120 is located in body 110, and fan blade 120 is used to blow air current to cooking cavity 1102 by rotating;Cover body 130, cover body 130 is covered in the outside of fan blade 120, and cover body 130 includes air outlet 1302, and air outlet 1302 is located in the circumferential side of fan blade 120, and the size of air outlet 1302 in the circumferential direction of fan blade 120 is greater than the size of air outlet 1302 in the axial direction of fan blade 120.

[0069] Figure 1 Arrow a shows the axial direction of fan blade 120, and arrow b shows the tangential direction of fan blade 120, and L shows the size of air outlet 1302 in the circumferential direction, and H shows the size of air outlet 1302 in the axial direction.

[0070] Figure 2 Arrow c shows the circumferential direction of fan blade 120.

[0071] Figure 3 Arrow d shows the flow direction of air outlet air current, and arrow e shows the flow direction of return air current.

[0072] In the embodiment, a kind of cooking equipment 100 is defined, and the cooking equipment 100 can be quickly heated to the skin of food by high-temperature air current, to obtain crisp and crisp outer skin, and food with attractive appearance, specifically cooking equipment 100 includes: air fryer, oven.

[0073] Cooking equipment 100 includes body 110, fan blade 120 and cover body 130, and body 110 is the main structure of cooking equipment 100, and body 110 forms the outer surface of cooking equipment 100, and body 110 is enclosed in cooking cavity 1102, and food is cooked in cooking cavity 1102.

[0074] Fan blade 120 is arranged on body 110, and fan blade 120 can rotate on body 110, and rotating fan blade 120 can disturb the flow of gas in body 110, and directional flow high-temperature air current can be blown into cooking cavity 1102 by cooperating heating component, so as to rapidly heat the skin of food by high-temperature air current.

[0075] The fan blade 120 includes an air outlet side and an air return side. The air outlet side is located on the circumferential side of the fan blade 120, and the air return side is located on the side of the fan blade 120 facing the cooking cavity 1102. The directional high-temperature airflow includes an air outlet airflow and an air return airflow. When the fan blade 120 rotates, the air outlet airflow first spreads in all directions, then flows from top to bottom along the side wall of the cooking cavity 1102 after contacting the side wall of the cooking cavity 1102, and then converges to the central region of the cooking cavity 1102, and forms the air return airflow flowing to the fan blade 120 after heating the food.

[0076] The cover body 130 covers the outside of the fan blade 120, and the cover body 130 is provided with an air outlet 1302 and an air return port 1322. The air outlet 1302 is located on the air outlet side of the fan blade 120, and the air return port 1322 is located on the air return side of the fan blade 120. The air outlet airflow needs to pass out of the cover body 130 through the air outlet 1302, and correspondingly, the air return airflow needs to enter the cover body 130 from the air return port 1322. The cover body 130 can play a protective role on the outside of the fan blade 120. On the one hand, it can avoid the rotating fan blade 120 from contacting the food, and on the other hand, it can avoid the user from being scratched by the fan blade 120 when accessing the food or cleaning the cooking cavity 1102. The cover body 130 can also play a role in blocking grease on the outside of the fan blade 120, thereby improving the cleanliness of the fan blade 120 and prolonging the cleaning cycle of the fan blade 120.

[0077] On this basis, the size of the air outlet 1302 in the circumferential direction of the fan blade 120 is the width of the air outlet 1302, and the size of the air outlet 1302 in the axial direction of the fan blade 120 is the height of the air outlet 1302. The width of the air outlet 1302 is greater than the height of the air outlet 1302.

[0078] Compared with the longitudinal opening in the related art, the transverse air outlet 1302 in the present application is more suitable for the flow direction of the air outlet airflow on the circumferential side of the fan blade 120, thereby reducing the wind resistance of the air outlet airflow to the air outlet 1302 and increasing the flow rate of the air outlet airflow. Moreover, the transverse air outlet 1302 can guide the air outlet airflow, thereby optimizing the wind field characteristics in the cooking cavity 1102 and further increasing the flow rate of the high-temperature airflow in the cooking cavity 1102.

[0079] As can be seen, by setting the air outlet 1302 with a width greater than a height, the heating rate and heating uniformity of the food in the cooking cavity 1102 can be improved, thereby solving the technical problem of poor food heating effect caused by large wind resistance of the safety cover and the safety cover not having a flow guiding function in the related art, and further achieving the technical effects of improving the quality of cooked food and improving the practicality of the cooking equipment 100.

[0080] Specifically, in this embodiment, the air outlet 1302 can be a vertically opened strip-shaped hole, or a special-shaped hole such as an oval hole or a rhombic hole. In this regard, this embodiment does not rigidly limit the shape of the air outlet 1302, and only needs to meet the size requirement that the width is greater than the height.

[0081] Figure 5 The wind field streamline diagram of the cooking device in the related art is shown, and the opening on the safety cover in the related art is a vertical hole, i.e., the size in the axial direction is greater than the size in the circumferential direction. It can be seen that in this case, the wind field streamline in the cooking cavity is relatively chaotic, and the flow rate is relatively low.

[0082] Figure 6 The wind field streamline diagram of the cooking device 100 according to one embodiment of the present application is shown. It can be seen that in the case of setting the transverse opening with the circumferential size greater than the axial size, the chaos degree of the wind field streamline in the cooking cavity 1102 is relatively low, and the flow rate is relatively high.

[0083] On this basis, under the condition that the air outlet 1302 has the same porosity and the heating food material is uniformly French fries, Figure 5 Scheme one is shown, Figure 6 Scheme two is shown. The heating effect of scheme one and scheme two can be shown by Table 1 below. It can be seen that the scheme proposed in the present application can improve the dehydration rate of French fries, thereby optimizing the taste of French fries.

[0084] Table 1

[0085] Scheme Setting temperature Preheating time Heating time Turnover time Dehydration rate Scheme 1 200℃ No preheating 15 min No turnover 45％ Scheme 2 200℃ No preheating 15 min No turnover 49.5％

[0086] As Figure 1 shown, in some embodiments of the present application, the air outlet 1302 is in a strip shape; the included angle between the tangential direction of the air outlet 1302 and the axial direction of the fan blade 120 ranges from greater than 45° to less than or equal to 90°.

[0087] In this embodiment, the air outlet 1302 is in a strip shape.

[0088] The included angle between the tangential direction of the air outlet 1302 and the axial direction of the fan blade 120 needs to be greater than 45° and less than or equal to 90°.

[0089] By limiting the above-mentioned included angle range, it can be ensured that the size of the strip-shaped air outlet 1302 in the circumferential direction is greater than the size in the axial direction, so as to reduce the air resistance of the air outlet 1302 to the air flow and improve the flow guiding effect of the air outlet 1302 to the air flow.

[0090] Specifically, the angle between the length direction of the air outlet 1302 and the axial direction of the fan blade 120 can be adjusted according to the shape of the blade on the fan blade 120, the orientation of the blade, and the number of blades to further reduce wind resistance and improve the flow guiding effect.

[0091] As shown in Figure 1 and Figure 3 shown, in some embodiments of the utility model, optionally, the tangential direction of the air outlet 1302 is perpendicular to the axial direction of the fan blade 120.

[0092] In this embodiment, the tangential direction of the air outlet 1302 is perpendicular to the axial direction of the fan blade 120, that is, the air outlet 1302 extends in the circumferential direction of the fan blade 120.

[0093] By setting the transverse air outlet 1302 with the tangential direction perpendicular to the axial direction of the fan blade 120, the shape of the air outlet 1302 can be adapted to the centrifugal fan wheel. On the one hand, the flow rate of the air outlet airflow diffused around the fan wheel is improved by reducing the wind resistance. On the other hand, the wind field characteristics in the cooking cavity 1102 are optimized by enhancing the guiding effect of the air outlet airflow, reducing the probability of turbulence and chaotic flow in the cooking cavity 1102, thereby achieving the technical effects of improving the cooking effect of the cooking equipment 100 and improving the practicability of the cooking equipment 100.

[0094] In some embodiments of the utility model, optionally, the ratio of the size of the air outlet 1302 in the tangential direction of the fan blade 120 to the size of the air outlet 1302 in the axial direction of the fan blade 120 is greater than 1 and less than or equal to 20.

[0095] In this embodiment, the ratio of the width of the air outlet 1302 to the height of the air outlet 1302 is greater than 1 and less than or equal to 20.

[0096] By limiting the ratio of the width of the air outlet 1302 to the height of the air outlet 1302 to be greater than 1, the resistance of the air outlet 1302 to the air outlet airflow can be effectively reduced, and the guiding effect of the air outlet 1302 to the air outlet airflow can be improved, thereby improving the airflow velocity in the cooking cavity 1102 and improving the heating efficiency of the food.

[0097] By limiting the ratio of the width of the air outlet 1302 to the height of the air outlet 1302 to be less than or equal to 20, the size of a single air outlet 1302 can be controlled on the basis of ensuring the low wind resistance demand and high flow guiding performance demand of the air outlet 1302, ensuring that the cover body 130 can provide effective protection for the inner blade, avoiding the food and the user from contacting the inner fan blade 120 through the air outlet 1302, and improving the blocking effect of the cover body 130 on the grease.

[0098] Specifically, the ratio of the size of the air outlet 1302 in the tangential direction of the fan blade 120 to the size of the air outlet 1302 in the axial direction of the fan blade 120 includes 3, 4, or 5.

[0099] As shown in Figure 1 and Figure 2 In some embodiments of the utility model, optionally, the cover body 130 includes an air outlet array 1304, the air outlet array 1304 includes a plurality of air outlets 1302, and the plurality of air outlets 1302 in the same air outlet array 1304 are uniformly distributed in the circumferential direction of the fan blade 120.

[0100] In this embodiment, the plurality of air outlets 1302 form an air outlet array 1304, and the cover body 130 is provided with at least one air outlet array 1304, wherein the plurality of air outlets 1302 belonging to the same air outlet array 1304 are spaced apart in the circumferential direction of the fan blade 120, and the plurality of air outlets 1302 are uniformly distributed around the fan blade 120, that is, the included angle between adjacent two air outlets 1302 is equal.

[0101] By arranging the air outlet array 1304 formed by the plurality of air outlets 1302, the air outlet 1302 can cover multiple angles around the fan blade 120, so that the air flow blown out by the fan blade 120 can be diffused in multiple directions into the cooking cavity 1102, thereby improving the heating uniformity of food and improving the quality of food.

[0102] By uniformly distributing the plurality of air outlets 1302 in the air outlet array 1304 around the fan blade 120, the uniformity of the air outlet of the cover body 130 can be further improved, thereby optimizing the wind field characteristics in the cooking cavity 1102, improving the heating uniformity of high-temperature airflow on food, and reducing the probability of turbulence and chaotic flow problems in the cooking cavity 1102.

[0103] As shown in Figure 1 and Figure 2 In some embodiments of the utility model, optionally, the number of air outlet arrays 1304 is a plurality; the plurality of air outlet arrays 1304 are distributed in the axial direction of the fan blade 120.

[0104] In this embodiment, the cover body 130 is provided with a plurality of air outlet arrays 1304, and the plurality of air outlet arrays 1304 are spaced apart in the circumferential direction of the fan blade 120.

[0105] For example, the cover body 130 includes three air outlet arrays 1304, one of which is located at the middle segment of the cover body 130, and the other two air outlet arrays 1304 are located on the upper and lower sides, respectively.

[0106] By increasing the number of air outlet arrays 1304, the area covered by the air outlet 1302 can be expanded, on the one hand, reducing the probability of dead air zones on the cover 130, and on the other hand, reducing the resistance of the cover 130 to the air flow, thereby improving the heating rate of the food by increasing the flow rate of the air flow, and improving the quality of the food.

[0107] As shown in Figure 1 and Figure 2 In some embodiments of the utility model, optionally, the air outlets 1302 on the two adjacent air outlet arrays 1304 are arranged in a staggered manner in the tangential direction of the fan blade 120.

[0108] In this embodiment, in the case where the cover 130 is distributed with a plurality of air outlet arrays 1304 in the axial direction of the fan blade 120, the air outlets 1302 of the two adjacent air outlet arrays 1304 in the axial direction of the fan blade 120 are arranged in a staggered manner, that is, the two adjacent air outlet arrays 1304 have a deflection angle in the circumferential direction of the fan blade 120.

[0109] Specifically, the deflection angle can be designed according to the size of the air outlet 1302, the number of air outlets 1302 in the air outlet array 1304, and the number of air outlet arrays 1304, which is not limited in this embodiment as long as it meets the staggered arrangement requirement.

[0110] By arranging the two adjacent air outlet arrays 1304 in a staggered manner, the air resistance of the air outlet 1302 to the air flow can be further reduced, thereby improving the air outlet speed of the cover 130 to improve the heating efficiency of the food. At the same time, arranging the two adjacent air outlet arrays 1304 in a staggered manner can also reduce the probability of turbulence and chaotic flow in the cooking cavity 1102, thereby improving the heating uniformity of the food and improving the quality of the cooked food.

[0111] As shown in Figure 2 and Figure 4 In some embodiments of the utility model, optionally, the cover 130 comprises a bottom plate 132, the bottom plate 132 is arranged on the side of the fan blade 120 facing the cooking cavity 1102, and the center of the bottom plate 132 comprises an air return port 1322; a side plate 134 connected with the bottom plate 132, the side plate 134 surrounds the bottom plate 132, and the air outlet 1302 is located on the side plate 134.

[0112] In this embodiment, the cover 130 comprises a bottom plate 132 and a side plate 134, the side plate 134 is connected with the edge of the bottom plate 132, and the side plate 134 surrounds the periphery of the bottom plate 132.

The directional high-temperature air flow includes the air outlet flow and the air return flow. When the fan blade 120 rotates, the air outlet flow is first diffused in all directions, passes through the side plate 134 through the air outlet 1302, contacts the side wall of the cooking cavity 1102, and flows from top to bottom under the guidance of the side wall of the cooking cavity 1102. Then, the air flow converges to the central region of the cooking cavity 1102, and forms the air return flow flowing to the fan blade 120 after heating the food. The air return flow enters the inside of the cover 130 through the air return port 1322 to participate in the next heating cycle of the high-temperature air flow.

[0114] The side plate 134 and the bottom plate 132 can play a protective role on the outside of the fan blade 120. On the one hand, the rotating fan blade 120 is prevented from contacting the food. On the other hand, the user is prevented from being scratched by the fan blade 120 when accessing the food or cleaning the cooking cavity 1102. The cover 130 can also play a role in blocking grease on the outside of the fan blade 120, thereby improving the cleanliness of the fan blade 120 and prolonging the cleaning cycle of the fan blade 120.

[0115] Specifically, the air return port 1322 is arranged at the center of the bottom plate 132. By arranging the air return port 1322 at the central region of the bottom plate 132, the cross-sectional area of the air return path can be increased, thereby improving the air flow circulation efficiency in the cooking device 100 and optimizing the heating effect of the cooking device 100 on the food.

[0119] Specifically, the inside of the cover body 114 is provided with a coating capable of reflecting heat radiation, thereby improving the heating efficiency of the food in the pot body 112.

[0120] The fan blades 120 and the cover body 130 are arranged inside the cover body 114, the cover body 114 is provided with a through hole 1142 opposite to the fan blades 120, and a motor for driving the fan blades 120 to rotate is arranged outside the cover body 114, so as to avoid the influence of a high-temperature environment on the normal work of the motor.

[0121] The through hole 1142 is provided with a light-transmitting plate 116, the light-transmitting plate 116 can cover the through hole 1142 after assembly, so as to prevent heat loss from the through hole 1142, and meanwhile, a user can observe food in the pot body 112 through the light-transmitting plate 116, so that the entire cooking process is visualized, which provides a convenient condition for the user to control the cooking process of the food, and thus realizes the technical effect of optimizing the user experience.

[0122] Specifically, the cover plate is a glass plate.

[0125] By arranging the supporting component 140, on the one hand, the distance between the food and the top heat source can be shortened, so that the heating rate of the food is improved, on the other hand, the supporting component 140 is provided with air holes through which high-temperature airflow can pass, and the high-temperature airflow can heat the lower surface of the food through the air holes on the supporting component 140, so that the entire outer surface of the food can be effectively heated. On the other hand, when cooking food with high moisture content, liquid will accumulate at the bottom of the pot body 112, and the supporting component 140 can support the food, so that the food is prevented from contacting the liquid, thereby ensuring that the crisp taste of the food is not destroyed, and the quality of the food is improved.

[0126] Specifically, the supporting component 140 comprises a baking tray and a tray.

[0127] As shown in Figure 3 In some embodiments of the utility model, the fan blades 120 have magnetic conductivity, and the cooking device 100 comprises an electromagnetic disk 150, which is arranged opposite to the fan blades 120.

[0128] In this embodiment, the fan blades 120 are prepared by using a material with magnetic conductivity, and specifically, the fan blades 120 can be prepared by using a metal material.

[0130] After being powered on, the electromagnetic disc 150 can generate an electromagnetic field in the area where the fan blade 120 is located, the magnetically conductive fan blade 120 is heated under the action of the electromagnetic field, and the high-temperature fan blade 120 can not only form a directional airflow during rotation but also heat the airflow to increase the temperature of the airflow, thereby achieving the technical effect of improving the heating efficiency of the cooking device 100. Moreover, compared with the heat pipe in the heat radiation heating scheme, the electromagnetic disc 150 itself generates relatively small heat, which is conducive to reducing the surface temperature of the cooking device 100, thereby reducing the probability of users being scalded and further improving the safety of the cooking device 100.

[0135] After being powered on, the electromagnetic disc 150 can generate an electromagnetic field in the area where the fan blade 120 is located, the magnetically conductive fan blade 120 is heated under the action of the electromagnetic field, and the high-temperature fan blade 120 can not only form a directional airflow during rotation but also heat the airflow to increase the temperature of the airflow, thereby achieving the technical effect of improving the heating efficiency of the cooking device 100. Moreover, compared with the heat pipe in the heat radiation heating scheme, the electromagnetic disc 150 itself generates relatively small heat, which is conducive to reducing the surface temperature of the cooking device 100, thereby reducing the probability of users being scalded and further improving the safety of the cooking device 100.
