Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The following is for reference. Figures 1-11 The cooking device 100 according to the present invention has a simple structure, can increase the amount of food cooked, reduce the thickness of food stacking, reduce hot air resistance, improve cooking uniformity and cooking speed, thereby improving the user experience.

[0038] like Figures 1-11 As shown, a cooking device 100 according to an embodiment of the present invention includes: a device body 1, a fan assembly 5, and a heating element 6.

[0039] The main body 1 of the device has a cooking cavity 33, and at least two cooking plates 34 are provided in the cooking cavity 33. The at least two cooking plates 34 are distributed at intervals in the vertical direction. A heating channel 341 is formed between two adjacent cooking plates 34. The fan assembly 5 is used to drive the airflow at the heating element 6 to continuously flow into the heating channel 341 from the first direction to heat the cooking plates 34. The first direction intersects with the vertical direction.

[0040] The cooking equipment 100 can be an air fryer or similar appliance, used for defrosting, frying, cooking, and baking food. It has a cooking cavity 33 inside, which forms a space to hold food. When using the equipment, the user can put the food into the cooking cavity 33 and then perform operations such as defrosting, frying, cooking, and baking to meet different user needs.

[0041] Specifically, the cooking device 100 is provided with a main body 1, and a cooking cavity 33 can be formed inside the main body 1. That is, the main body 1 is a shell structure, and the cooking cavity 33 is defined inside. The user can place food in the cooking cavity 33 to cook the food as needed. The cooking cavity 33 is provided with a cooking plate 34, which is configured to have at least two layers. That is, the cooking plate 34 can be configured to have two, three, or four layers, etc. The user can place food in the cooking plate 34, and the cooking plate 34 is configured to have at least two layers, so that at least two layers of cooking plate 34 can hold food, thereby increasing the amount of food that can be cooked to meet the user's large capacity needs.

[0042] In addition, at least two cooking trays 34 are spaced apart in the vertical direction, and a heating channel 341 is formed between two adjacent cooking trays 34. That is, when the cooking device 100 is running, the food in each cooking tray 34 can be heated separately. Placing the food in at least two cooking trays 34 can reduce the thickness of the food stack, increase the cooking speed, and improve the cooking uniformity. In actual installation, cooking holes 341 can be provided on the bottom wall and side wall of the cooking tray 34 to ensure the consistency of the cooking degree of the food surface and the bottom layer.

[0043] Furthermore, the cooking device 100 is also provided with a fan assembly 5 and a heating element 6. The heating element 6 can be configured as a heating tube or the like. The heating element 6 can heat the surrounding airflow, and thus the food can be cooked by the heated airflow. The fan assembly 5 is rotatable relative to the main body 1 of the device. When the fan assembly 5 rotates, it can drive the airflow around the fan assembly 5, so that the airflow in the cooking cavity 33 can flow, and thus the food in the cooking cavity 33 can be heated in various places.

[0044] When the fan assembly 5 is running, it can drive the airflow in the cooking cavity 33 to flow, and the airflow at the heating element 6 is heated by the heating element 6 and its temperature rises, thereby forming a high-temperature airflow. The fan assembly 5 can drive the high-temperature airflow to continuously flow into the heating channel 341 from the first direction. A heating channel 341 is formed between two adjacent cooking plates 34 spaced apart in the vertical direction, and the first direction intersects with the vertical direction, so that part of the high-temperature airflow in the heating channel 341 can heat the upper part of the food in the lower cooking plate 34, and another part of the high-temperature airflow can heat the lower part of the food in the upper cooking plate 34, and so on, so that the high-temperature airflow in the heating channel 341 can heat the upper and lower parts of the food in each cooking plate 34 at the same time, thereby improving the cooking speed.

[0045] In addition, the cooking tray 34 is set to at least two layers. When the amount of food to be cooked is fixed, setting at least two layers of cooking tray 34 can reduce the stacking thickness of the food in each layer of cooking tray 34. The resistance of food to airflow is exponentially related to its stacking thickness. When the stacking thickness of food is reduced, the resistance of food to airflow is also reduced, which makes it easier for high-temperature airflow to penetrate the food, thereby improving the uniformity of cooking the upper and lower parts of the food in each layer of cooking tray 34 and improving the user experience.

[0046] Meanwhile, the fan assembly 5 and the heating element 6 are both located in the second direction of the cooking chamber 33, and the airflow in the cooking chamber 33 is adapted to flow from the second direction to the heating element 6. The first direction and the second direction intersect, that is, the fan assembly 5 can transport the high-temperature airflow at the heating element 6 into the heating channel 341 along the first direction to heat the upper and lower parts of the food in each cooking plate 34 at the same time. The fan assembly 5 and the heating element 6 are both arranged in the second direction of the cooking chamber 33, that is, the fan assembly 5 and the heating element 6 are arranged facing each other along the second direction, so that the airflow heated by the heating element 6 can be directly transported through the fan assembly 5, reducing the transport distance, thereby reducing the energy loss of the airflow during the transport process and reducing the operating energy consumption of the cooking equipment 100.

[0047] Furthermore, the heated high-temperature airflow can enter the cooking cavity 33 along the first direction, and the airflow that has heated the food in the cooking cavity 33 can flow towards the heating element 6 along the second direction. The first direction and the second direction intersect, that is, the flow direction of the high-temperature airflow and the flow direction of the airflow after cooking the food are different, so that the flow direction of the high-temperature airflow changes after flowing into the cooking cavity 33, thereby increasing the length of the flow path of the high-temperature airflow in the cooking cavity 33, increasing the area of ​​the food cooked by the high-temperature airflow, thereby improving the consistency of the cooking effect on all parts of the food and improving the user experience.

[0048] In addition, the airflow in the cooking cavity 33 flows from the second direction to the heating element 6, which is located in the second direction of the cooking cavity 33. This allows the airflow after cooking the food to flow directly to the heating element 6, so that after being heated by the heating element 6, it can be delivered back into the cooking cavity 33 by the fan assembly 5. This shortens the length of the airflow path outside the cooking cavity 33, reduces the energy loss of the airflow during the delivery process, and reduces the operating energy consumption of the cooking equipment 100.

[0049] Furthermore, the fan assembly 5 includes a first fan 51 and a second fan 52, which are coaxially arranged. The airflow from the cooking cavity 33 is adapted to flow sequentially through the first fan 51 and the second fan 52 before entering the cooking cavity 33. The fan assembly 5 can drive the high-temperature airflow, and as... Figures 1-3 As shown, the fan assembly 5 is provided with a first fan 51 and a second fan 52. The first fan 51 and the second fan 52 are coaxially arranged and relatively fixed, so that the first fan 51 and the second fan 52 can rotate synchronously. The fan assembly 5 is provided with two fans, and the two fans can rotate at the same time, which can improve the driving force of the airflow, thereby increasing the static pressure of the high-temperature airflow, so as to improve the penetration of the high-temperature airflow, allowing the high-temperature airflow to heat the inside of the food and improve the uniformity of cooking the food.

[0050] Furthermore, the heating element 6 and the fan assembly 5 are distributed along the second direction. The first fan 51 and the second fan 52 are coaxially arranged and also distributed along the second direction. The airflow from the cooking cavity 33 is adapted to flow through the first fan 51 and the second fan 52 in sequence before entering the cooking cavity 33. That is, the airflow from the cooking cavity 33 can flow to the heating element 6 for heating to form a high-temperature airflow. The high-temperature airflow can flow through the first fan 51 and the second fan 52 in sequence, so that the first fan 51 can perform a first-stage pressurization on the high-temperature airflow, and the second fan 52 can perform a second-stage pressurization on the high-temperature airflow. Thus, the high-temperature airflow after two pressurizations can flow into the cooking cavity 33 to heat the food, increase the static pressure of the high-temperature airflow, and thus increase the penetration power of the high-temperature airflow, so that the high-temperature airflow can heat the inside of the food and improve the uniformity of cooking the food.

[0051] According to the embodiment of the present invention, the cooking device 100 has at least two layers of cooking plates 34 spaced apart in the vertical direction in the cooking cavity 33, so that each cooking plate 34 can hold food. The structure is simple, which can increase the amount of food cooked and reduce the thickness of the food stack, thereby reducing the resistance of hot air. At the same time, a heating channel 341 is formed between the cooking plates 34, and the airflow heated by the heating element 6 can flow into the heating channel 341 to heat the cooking plates 34, thereby heating the food in each cooking plate 34, improving the uniformity of cooking and the cooking speed, thereby improving the user experience, the effect of use, and the scope of application.

[0052] In some embodiments, a first fan 51 is disposed in a direction close to the cooking chamber 33, and a second fan 52 is disposed in a direction away from the cooking chamber 33 relative to the first fan 51. The first fan 51 is configured as an axial fan, and the second fan 52 is configured as a centrifugal fan.

[0053] Specifically, the first fan 51 is positioned close to the cooking cavity 33, and the second fan 52 is positioned further away from the cooking cavity 33 than the first fan 51. That is, the distance between the first fan 51 and the cooking cavity 33 is set to be smaller, and the distance between the second fan 52 and the cooking cavity 33 is set to be larger. This allows the airflow to first contact the first fan 51 after flowing out of the cooking cavity 33 and being heated by the heating element 6 to form a high-temperature airflow. The high-temperature airflow can then be pressurized by the first fan 51 and then transported to the second fan 52 in the second direction for secondary pressurization, ensuring the reliability of sequential pressurization.

[0054] And such as Figures 7-8 As shown, the first fan 51 is constructed as an axial fan, and the second fan 52 is constructed as a centrifugal fan. The heating element 6 and the first fan 51 are distributed along the second direction, and the first fan 51 and the second fan 52 are also distributed along the second direction. The first fan 51 is constructed as an axial fan so that while the first fan 51 pressurizes the high-temperature airflow, it can also transport the high-temperature airflow at the heating element 6 to the second fan 52 along the second direction.

[0055] In addition, the direction of the airflow out of the cooking chamber 33 is different from the direction of the high-temperature airflow into the cooking chamber 33. The second fan 52 is constructed as a centrifugal fan, so that when the airflow flows axially to the second fan 52, the second fan 52 can pressurize the high-temperature airflow a second time and transport the pressurized high-temperature airflow in the radial direction. This makes the flow direction of the high-temperature airflow after secondary pressurization different from the flow direction of the airflow from the cooking chamber 33 to the heating element 6, thereby avoiding airflow mixing and ensuring the reliability of high-temperature airflow delivery.

[0056] In some embodiments, the outer diameter of the first fan 51 is smaller than the outer diameter of the second fan 52, and the second fan 52 has a clearance space on the side facing the cooking cavity 33, with at least a portion of the first fan 51 located within the clearance space.

[0057] Specifically, the high-temperature airflow can be pressurized twice by the first fan 51 and the second fan 52 to improve the penetration effect of the high-temperature airflow. The outer diameter of the first fan 51 is set to be smaller than that of the second fan 52, that is, the outer diameter of the first fan 51 is set to be smaller and the outer diameter of the second fan 52 is set to be larger. The first fan 51 can transport the high-temperature airflow axially, and the second fan 52 can transport the high-temperature airflow radially. Setting the outer diameter of the first fan 51 to be smaller can reduce the range of the high-temperature airflow transported by the first fan 51 axially, so as to avoid the high-temperature airflow transported by the second fan 52 radially. This can prevent the high-temperature airflow after the first stage of pressurization transported by the first fan 51 from mixing with the high-temperature airflow after the second stage of pressurization transported by the second fan 52, which would affect the pressurization effect of the high-temperature airflow and ensure the reliability of the secondary pressurization of the high-temperature airflow.

[0058] In addition, the second fan 52 has a clearance space on the side facing the cooking cavity 33. The clearance space is open to the first fan 51, and the part of the second fan 52 near the first fan 51 is recessed towards the side away from the first fan 51. At least a part of the first fan 51 can be placed in the clearance space, so that the high-temperature airflow flowing to the first fan 51 can be delivered to the second fan 52 through the first fan 51, thereby increasing the delivery rate of the high-temperature airflow. This can increase the static pressure of the high-temperature airflow and the intake efficiency of the high-temperature airflow, thereby improving the uniformity and speed of cooking and improving the user experience.

[0059] In some embodiments, the distance between the side of the first fan 51 near the cooking cavity 33 and the cooking cavity 33 is smaller than the distance between the side of the second fan 52 near the cooking cavity 33 and the cooking cavity 33.

[0060] Specifically, the high-temperature airflow can flow sequentially along the second direction to the first fan 51 and the second fan 52. The distance between the side of the first fan 51 near the cooking cavity 33 and the cooking cavity 33 is set to be smaller than the distance between the side of the second fan 52 near the cooking cavity 33 and the cooking cavity 33. That is, the distance between the side of the first fan 51 near the cooking cavity 33 and the cooking cavity 33 is set to be smaller, and the distance between the side of the second fan 52 near the cooking cavity 33 and the cooking cavity 33 is set to be larger. This allows the airflow to first contact the side of the first fan 51 near the cooking cavity 33 after flowing out of the cooking cavity 33 and being heated by the heating element 6 to form a high-temperature airflow. The high-temperature airflow can then first contact the side of the first fan 51 near the cooking cavity 33 to be pressurized by the first fan 51, and then be transported along the second direction to the second fan 52 to be pressurized by the second fan 52, ensuring the reliability of sequential pressurization.

[0061] In other embodiments, the distance between the side of the first fan 51 away from the cooking cavity 33 and the cooking cavity 33 is smaller than the distance between the side of the second fan 52 away from the cooking cavity 33 and the cooking cavity 33.

[0062] Specifically, the high-temperature airflow can flow sequentially along the second direction to the first fan 51 and the second fan 52. The distance between the side of the first fan 51 away from the cooking cavity 33 and the cooking cavity 33 is set to be smaller than the distance between the side of the second fan 52 away from the cooking cavity 33 and the cooking cavity 33. That is, the distance between the side of the first fan 51 away from the cooking cavity 33 and the cooking cavity 33 is set to be smaller, and the distance between the side of the second fan 52 away from the cooking cavity 33 and the cooking cavity 33 is set to be larger. This allows the airflow to be pressurized in the first stage by the first fan 51 and then transported to the second fan 52 along the second direction by the first fan 51, and then pressurized in the second stage by the second fan 52, ensuring the reliability of sequential pressurization.

[0063] In some embodiments, the outer diameter of the first fan 51 is set to D1, and the outer diameter of the second fan 52 is set to D2, and satisfies: 0.45≤D1 / D2≤0.63.

[0064] Specifically, the fan assembly 5 is equipped with a first fan 51 and a second fan 52, which can perform secondary pressurization on the high-temperature airflow, and as... Figure 7 As shown, the outer diameter of the first fan 51 is set to D1, and the outer diameter of the second fan 52 is set to D2, satisfying: 0.45≤D1 / D2≤0.63. That is, the ratio between the outer diameter D1 of the first fan 51 and the outer diameter D2 of the second fan 52 can be set to 0.45, 0.48, 0.5, 0.53, 0.56, 0.59, 0.62, or 0.63, etc. Setting the ratio between the outer diameter D1 of the first fan 51 and the outer diameter D2 of the second fan 52 to satisfy: 0.45≤D1 / D2≤0.63 means that the outer diameter D1 of the first fan 51 is set to be smaller than the outer diameter D2 of the second fan 52.

[0065] Furthermore, the first fan 51 can transport the high-temperature airflow axially, and the second fan 52 can transport the high-temperature airflow radially. By setting the outer diameter of the first fan 51 to be smaller, the range of the high-temperature airflow transported by the first fan 51 axially can be reduced, so as to avoid the high-temperature airflow transported radially by the second fan 52. This can prevent the high-temperature airflow after the first stage of pressurization transported by the first fan 51 from mixing with the high-temperature airflow after the second stage of pressurization transported by the second fan 52, which would affect the pressurization effect of the high-temperature airflow and ensure the reliability of the secondary pressurization of the high-temperature airflow.

[0066] Preferably, in this embodiment, D1 can be set to 74mm, D2 can be set to 145mm, and D1 / D2 is 0.51.

[0067] In some embodiments, the axial thickness of the first fan 51 is set to H1, the axial thickness of the second fan 52 is set to H2, the distance between the side of the first fan 51 away from the cooking cavity 33 and the side of the second fan 52 away from the cooking cavity 33 is set to H3, and satisfies: 0.78≤H1 / H2≤0.96, 0.21≤H3 / H2≤0.36.

[0068] Specifically, such as Figure 8 As shown, the axial thickness of the first fan 51 is set to H1, and the axial thickness of the second fan 52 is set to H2, satisfying 0.78≤H1 / H2≤0.96. That is, the ratio between the axial thickness H1 of the first fan 51 and the axial thickness H2 of the second fan 52 can be set to 0.78, 0.81, 0.84, 0.87, 0.9, 0.93, 0.95, or 0.96, etc. Setting the ratio between the axial thickness H1 of the first fan 51 and the axial thickness H2 of the second fan 52 to satisfy 0.78≤H1 / H2≤0.96, that is, setting the axial thickness H1 of the first fan 51 to be smaller than the axial thickness H2 of the second fan 52, can reduce the path length of the high-temperature airflow through the first fan 51, thereby increasing the flow speed of the high-temperature airflow. Setting the axial thickness H2 of the second fan 52 to be larger can ensure the reliability of the second fan 52 in conveying the high-temperature airflow radially.

[0069] Furthermore, the distance between the side of the first fan 51 facing away from the cooking cavity 33 and the side of the second fan 52 facing away from the cooking cavity 33 is set to H3, and satisfies: 0.21≤H3 / H2≤0.36, that is, the ratio between the distance H3 between the side of the first fan 51 facing away from the cooking cavity 33 and the side of the second fan 52 facing away from the cooking cavity 33 and the axial thickness H2 of the second fan 52 can be set to 0.21, 0.24, 0.27, 0.3, 0.33, 0.35 or 0.36, etc., that is, the first The distance H3 between the side of the first fan 51 away from the cooking cavity 33 and the side of the second fan 52 away from the cooking cavity 33 is set to be less than the axial thickness H2 of the second fan 52. This can prevent the distance between the side of the first fan 51 away from the cooking cavity 33 and the side of the second fan 52 away from the cooking cavity 33 from being too small, which would affect the flow of high-temperature airflow. It can also prevent the distance between the side of the first fan 51 away from the cooking cavity 33 and the side of the second fan 52 away from the cooking cavity 33 from being too large, which would affect the pressurization effect and ensure the reliability of secondary pressurization of airflow.

[0070] Preferably, in this embodiment, H1 can be set to 16mm, H2 can be set to 18mm, H3 can be set to 4.9mm, H1 / H2 is 0.88, and H3 / H2 is 0.27.

[0071] In some embodiments, the outer diameter of the second fan 52 is greater than the distance between the uppermost cooking plate 34 and the lowermost cooking plate 34.

[0072] Specifically, the airflow in the cooking cavity 33 can flow out toward the heating element 6, and after being pressurized twice by the first fan 51 and the second fan 52, it flows into the cooking cavity 33 in the first direction to heat the food in at least two cooking plates 34. The outer diameter of the second fan 52 is set to be larger than the distance between the uppermost cooking plate 34 and the lowermost cooking plate 34, that is, the outer diameter of the second fan 52 is set to be larger, and the distance between the uppermost cooking plate 34 and the lowermost cooking plate 34 is set to be smaller. The second fan 52 is a centrifugal fan, and the airflow flowing to the second fan 52 can be transported radially along the second fan 52.

[0073] Thus, by setting the outer diameter of the second fan 52 to be larger, the air delivery range of the second fan 52 can be increased. Furthermore, by setting the distance between the uppermost cooking plate 34 and the lowermost cooking plate 34 to be smaller than the outer diameter of the second fan 52, the high-temperature airflow delivered by the second fan 52 into the cooking cavity 33 can flow towards each cooking plate 34, ensuring the reliability of heating the food in each cooking plate 34, thereby improving the uniformity of cooking and enhancing the user experience.

[0074] In some embodiments, there are at least three cooking plates 34, and the first fan 51 is distributed opposite to the middle cooking plate 34 along a second direction.

[0075] Specifically, a cooking plate 34 is provided inside the cooking cavity 33 for placing food, and the cooking plate 34 can be set to at least three, that is, the cooking plate 34 can be set to three, four or five, etc. In this embodiment, for example... Figure 3-5 As shown, there are three cooking plates 34, which are evenly spaced apart in the vertical direction, so that the high-temperature airflow can be evenly distributed to each cooking plate 34 to improve the uniformity of cooking.

[0076] Furthermore, the airflow in the cooking cavity 33 can flow towards the heating element 6 in the second direction, and then towards the first fan 51 in the second direction. The first fan 51 is configured to be distributed directly opposite the cooking plate 34 located in the middle in the second direction. That is, after the high-temperature airflow at each cooking plate 34 has heated the food, it can flow through the heating element 6 and then towards the first fan 51, so that the airflow at the upper cooking plate 34 and the airflow at the lower cooking plate 34 have the same path to the first fan 51, so as to ensure the consistency of airflow at all places and ensure the gas flow rate.

[0077] In some embodiments, the first direction and the second direction are perpendicular to each other and are also perpendicular to the up and down directions, respectively.

[0078] Specifically, the high-temperature airflow, after being pressurized twice by the first fan 51 and the second fan 52, can enter the cooking chamber 33 along the first direction, and the airflow after heating the food can flow sequentially towards the heating element 6 and the fan assembly 5 along the second direction. The first and second directions are set to be perpendicular, so that the direction of the high-temperature airflow flowing into the cooking chamber 33 is perpendicular to the direction of the airflow flowing out of the cooking chamber 33. This allows the high-temperature airflow to heat the food after flowing into the cooking chamber 33, and after heating, it needs to change direction before flowing out of the cooking chamber 33, increasing the length of the airflow path in the cooking chamber 33, thereby increasing the range of the airflow heating the food, and ensuring the reliability of heating all parts of the food.

[0079] Furthermore, the cooking plate 34 is configured with at least two layers, and the at least two layers of cooking plates 34 are distributed at intervals in the vertical direction, that is, each layer of cooking plate 34 extends in the horizontal direction. The first direction and the second direction are respectively perpendicular to the vertical direction, so that the first direction and the second direction are both located in the horizontal direction. That is, the high-temperature airflow flows into the cooking cavity 33 and the airflow flows out of the cooking cavity 33 in the horizontal direction. This makes the airflow direction parallel to the extension direction of the cooking plate 34, so that the airflow can evenly heat the upper and lower parts of the cooking plate 34, thereby ensuring the uniformity of food heating and improving the user experience.

[0080] In some embodiments, the main body 1 of the device includes an inner cooking shell 3 and an outer cooking shell 2. The inner cooking shell 3 is located inside the outer cooking shell 2, and a cooking cavity 33 is formed inside the inner cooking shell 3. An air supply channel 4 is defined between the outer cooking shell 2 and the inner cooking shell 3. The air supply channel 4 communicates with the cooking cavity 33, and the fan assembly 5 and the heating element 6 are both located inside the air supply channel 4.

[0081] Specifically, the cooking cavity 33 is formed within the main body 1 of the equipment, and as... Figure 2 As shown, the main body of the device 1 includes an inner cooking shell 3 and an outer cooking shell 2. The outer cooking shell 2 is located outside the main body of the device 1, and the inner cooking shell 3 is located inside the main body of the device 1. The inner cooking shell 3 is located inside the outer cooking shell 2. The inner wall of the inner cooking shell 3 defines a cooking cavity 33, and the inner wall of the inner cooking shell 3 is provided with a limiting groove extending in the horizontal direction. The edge of the cooking plate 34 can extend into the limiting groove so that at least two cooking plates 34 can be distributed in the cooking cavity 33 at intervals in the vertical direction.

[0082] Furthermore, the outer cooking shell 2 and the inner cooking shell 3 are spaced apart, and an air supply channel 4 can be defined between the outer cooking shell 2 and the inner cooking shell 3. The fan assembly 5 and the heating element 6 are both disposed in the air supply channel 4, so that when the fan assembly 5 is running, it can pressurize the high-temperature airflow at the heating element 6 a second time, and then transport the high-temperature airflow after secondary pressurization along the air supply channel 4. The air supply channel 4 is connected to the cooking chamber 33, so that the high-temperature airflow in the air supply channel 4 can flow along the air supply channel 4 to the cooking chamber 33. The airflow after cooking the food in the cooking chamber 33 can also flow back into the air supply channel 4, so as to be reheated and pressurized by the heating element 6 and the fan assembly 5, so that the airflow can circulate in the main body of the equipment 1, thereby improving the cooking reliability.

[0083] In some embodiments, the inner cooking shell 3 is formed with a first air inlet 321 and a first air outlet 311 spaced apart. The first air inlet 321 is used to connect the cooking cavity 33 and the air supply channel 4 along a first direction, and the first air outlet 311 is used to connect the cooking cavity 33 and the air supply channel 4 along a second direction. The first direction and the second direction intersect.

[0084] Specifically, an airflow channel 4 is formed between the outer cooking shell 2 and the inner cooking shell 3, and as shown... Figure 2 As shown, the inner cooking shell 3 has a first air inlet 321 and a first air outlet 311. Both the first air inlet 321 and the first air outlet 311 are connected to the air supply channel 4. A cooking cavity 33 is formed inside the inner cooking shell 3, so that the air supply channel 4 can be connected to the cooking cavity 33 through the first air inlet 321 and the first air outlet 311. The airflow in the air supply channel 4 can enter the cooking cavity 33 through the first air inlet 321, and the airflow in the cooking cavity 33 can flow to the air supply channel 4 through the first air outlet 311. The first air inlet 321 and the first air outlet 311 are spaced apart, which can increase the length of the airflow path in the cooking cavity 33, thereby increasing the area for cooking food and improving the cooking effect.

[0085] Furthermore, the first air inlet 321 can connect the cooking cavity 33 and the air supply channel 4 along the first direction, so that the high-temperature airflow in the air supply channel 4 can flow into the cooking cavity 33 along the first direction. The first air outlet 311 can connect the cooking cavity 33 and the air supply channel 4 along the second direction, so that the airflow after heating the food in the cooking cavity 33 can flow into the air supply channel 4 along the second direction. The first direction and the second direction intersect, so that the flow direction of the high-temperature airflow entering the cooking cavity 33 intersects with the flow direction of the airflow exiting the cooking cavity 33. That is, the flow direction of the high-temperature airflow in the cooking cavity 33 changes, thereby increasing the length of the airflow path in the cooking cavity 33, increasing the area for cooking the food, and improving the cooking effect.

[0086] In some embodiments, the inner cooking shell 3 includes an air outlet sidewall 31 and two air inlet sidewalls 32. The two air inlet sidewalls 32 are spaced apart and distributed opposite each other along a first direction. The air outlet sidewall 31 is connected to the two air inlet sidewalls 32 respectively. The air outlet sidewall 31 is provided with a first air outlet 311, and at least one of the two air inlet sidewalls 32 is provided with a first air inlet 321.

[0087] Specifically, the cooking device 100 can be set as a rectangle, so that both the outer cooking shell 2 and the inner cooking shell 3 can be set as rectangles. The inner cooking shell 3 can be provided with an air outlet sidewall 31 and two air inlet sidewalls 32. The air outlet sidewall 31 extends along a first direction, and the two air inlet sidewalls 32 extend along a second direction. The two air inlet sidewalls 32 are spaced apart and distributed opposite each other along the first direction. The air outlet sidewall 31 is connected to the two air inlet sidewalls 32 respectively. That is, the two sides of the air outlet sidewall 31 along the first direction are connected to the two air inlet sidewalls 32 respectively, so that the air outlet sidewall 31 and the two air inlet sidewalls 32 together form the complete sidewall of the inner cooking shell 3. The components inside the inner cooking shell 3 can be installed and fixed through the sidewalls to ensure installation reliability.

[0088] In some embodiments, when the cooking device 100 is an air fryer, the air inlet side wall 32 is the side wall of the frying drum, the cooking tray 34 is a baking tray, the cooking tray 34 is placed on the frying drum, and the frying drum can be pulled out and placed in the cooking device 100 along the second direction. Alternatively, the cooking device 100 is provided with a flip cover along the arrangement direction of the cooking tray 34, and the frying drum can be placed in the cooking device 100 along that direction.

[0089] Furthermore, the first air outlet 311 is disposed on the air outlet side wall 31, meaning that the airflow in the cooking cavity 33 can flow from the air outlet side wall 31 to the air supply channel 4. At least one of the two air inlet side walls 32 is provided with a first air inlet 321. This means that only one of the two air inlet side walls 32 can have a first air inlet 321, or both air inlet side walls 32 can have a first air inlet 321. In this embodiment, for example... Figure 2 As shown, a first air inlet 321 can be provided on both air inlet sidewalls 32, so that the high-temperature airflow in the air supply channel 4 can flow from the two air inlet sidewalls 32 to the cooking cavity 33, thereby changing the airflow direction in the cooking cavity 33, increasing the area for cooking food and improving the cooking effect.

[0090] In some embodiments, the air supply channel 4 includes an air outlet channel 41 and two air inlet channels 42. The air outlet channel 41 is formed between the air outlet sidewall 31 and the outer cooking shell 2 and communicates with the first air outlet 311. The two air inlet channels 42 are respectively formed between the outer cooking shell 2 and the two air inlet sidewalls 32, and the two air inlet channels 42 are used to communicate the air outlet channel 41 with the two first air inlets 321 respectively. The fan assembly 5 and the heating element 6 are both located in the air outlet channel 41.

[0091] Specifically, the air supply duct 4 is connected to the cooking cavity 33, and as follows: Figure 2 As shown, the air supply duct 4 includes an air outlet duct 41 and two air inlet ducts 42. The air outlet duct 41 extends along a first direction, and the two air inlet ducts 42 extend along a second direction. The two air inlet ducts 42 are spaced apart and distributed opposite each other along the first direction. The air outlet duct 41 is connected to the two air inlet ducts 42 respectively, that is, the two sides of the air outlet duct 41 along the first direction are connected to the two air inlet ducts 42 respectively.

[0092] Furthermore, the air outlet channel 41 can be formed between the air outlet sidewall 31 and the outer cooking shell 2, and the air outlet channel 41 is connected to the first air outlet 311, so that the airflow in the cooking cavity 33 can flow through the first air outlet 311 to the air outlet channel 41. Two air inlet channels 42 are respectively formed between the outer cooking shell 2 and the two air inlet sidewalls 32, and the two air inlet channels 42 are used to connect the air outlet channel 41 to the two first air inlets 321 respectively, that is, the airflow in the air outlet channel 41 can flow to the two air inlet channels 42 respectively, and the airflow in the two air inlet channels 42 can flow to the cooking cavity through the corresponding first air inlets 321 respectively.

[0093] In addition, both the fan assembly 5 and the heating element 6 are located inside the air outlet channel 41, so that the airflow flowing from the first air outlet 311 into the air outlet channel 41 in the cooking cavity 33 can be heated by the heating element 6, and can be pressurized again by the fan assembly 5 and flow into the two air inlet channels 42 respectively, so that the high temperature and high pressure airflow can enter the cooking cavity 33 from both sides of the cooking cavity 33 through the two air inlet channels 42 respectively, thereby heating the food in the cooking cavity 33 from multiple directions, improving the cooking speed and cooking uniformity, and improving the user experience.

[0094] In some embodiments, the air outlet duct 41 is provided with an air guide volute 43, the air guide volute 43 is provided with a second air inlet 431 and two second air outlets 432, the second air inlet 431 is arranged opposite to the fan assembly 5 along the second direction, and the two second air outlets 432 are respectively connected to the two air inlet ducts 42.

[0095] Specifically, the airflow from the cooking cavity 33 can flow into the air outlet channel 41, and the air outlet channel 41 is provided with a guide volute 43. The guide volute 43 can be installed on the inner wall of the outer cooking shell 2 by welding or other means. The fan assembly 5 can be set in the guide volute 43 or between the guide volute 43 and the inner wall of the outer cooking shell 2. The guide volute 43 is provided with a second air inlet 431 and two second air outlets 432. The second air inlet 431 is configured to communicate with the air outlet channel 41, so that the airflow in the air outlet channel 41 can enter the guide volute 43 through the second air inlet 431. The two second air outlets 432 are respectively connected to the two air inlets 42, so that the airflow in the guide volute 43 can flow into the corresponding air inlets 42 through the two second air outlets 432.

[0096] Furthermore, the second air inlet 431 and the fan assembly 5 are arranged facing each other along the second direction, and the heating element 6 and the fan assembly 5 are distributed along the second direction. This allows the high-temperature airflow heated by the heating element 6 to enter the air guide volute 43 along the second direction through the second air inlet 431 under the drive of the fan assembly 5. The high-temperature airflow can be pressurized a second time in the air guide volute 43 by the fan assembly 5, and the pressurized high-temperature airflow can flow along the inner wall of the air guide volute 43 to the two second air outlets 432 under the action of the fan assembly 5. Then, it flows into the corresponding air inlet channel 42 through the two second air outlets 432. The air guide volute 43 can pressurize the high-temperature airflow again after the second pressurization, thereby improving the penetration of the high-temperature airflow and improving the cooking effect of the high-temperature airflow on the food, so as to improve the cooking speed and cooking uniformity of the food.

[0097] In some embodiments, the heating element 6 is located between the first air outlet 311 and the second air inlet 431.

[0098] Specifically, the air outlet sidewall 31 of the inner cooking shell 3 is provided with a first air outlet 311, which is connected to the air outlet channel 41, so that the airflow in the cooking cavity 33 can flow through the first air outlet 311 to the air outlet channel 41. The second air inlet 431 is connected to the air outlet channel 41, and the airflow in the air outlet channel 41 can enter the air guide volute 43 through the second air inlet 431 under the drive of the fan assembly 5. The heating element 6 is disposed in the air outlet channel 41 and is located between the first air outlet 311 and the second air inlet 431. That is, the airflow flowing out of the cooking cavity 33 through the first air outlet 311 can be heated at the heating element 6 and then flow directly into the air guide volute 43 through the second air inlet 431, reducing the length of the airflow path and thus reducing the energy loss generated by the airflow during flow, thereby reducing the energy consumption of the cooking equipment 100 during operation.

[0099] In some embodiments, the cooking device 100 further includes a device housing 7, an outer cooking shell 2 located inside the device housing 7, and an installation cavity 73 formed between the device housing 7 and the outer cooking shell 2. The installation cavity 73 is provided with a drive motor 731 and a cooling fan 732, and the output end of the drive motor 731 is sequentially connected to the cooling fan 732 and the fan assembly 5.

[0100] Specifically, such as Figures 4-6 As shown, the cooking device 100 is provided with a device housing 7, which can be cylindrical, rectangular, etc. The device housing 7 is located on the outermost side of the cooking device 100, which can protect the internal structure of the cooking device 100 and provide mounting points for the internal components of the cooking device 100. The outer cooking shell 2 is located inside the device housing 7, and when the outer cooking shell 2 is installed inside the device housing 7, there is a gap between the outer wall of the outer cooking shell 2 and the inner wall of the device housing 7, which allows the outer wall of the outer cooking shell 2 and the inner wall of the device housing 7 to define a mounting cavity 73. The mounting cavity 73 can be used to install the components required for the operation of the cooking device 100.

[0101] And such as Figures 1-3 As shown, the mounting cavity 73 is equipped with a drive motor 731 and a cooling fan 732. The drive motor 731 is provided with a drive shaft. The drive motor 731 is installed in the mounting cavity 73. The drive shaft of the drive motor 731 is located on the side of the drive motor 731 facing the cooking cavity 33 and extends towards the cooking cavity 33. The drive shaft can pass through the outer cooking shell 2, so that the drive shaft can be connected to the cooling fan 732 and the fan assembly 5 in sequence.

[0102] Furthermore, the drive motor 731 can drive the drive shaft to rotate, thereby enabling the drive shaft to drive the cooling fan 732 and the fan assembly 5 to rotate. In the second direction, the cooling fan 732 is located between the drive motor 731 and the outer cooking shell 2, and the cooling fan 732 and the fan assembly 5 are respectively located on both sides of the outer cooking shell 2. The cooling fan 732 can dissipate heat from the drive motor 731, ensuring the reliable operation of the drive motor 731. In some embodiments, when the cooking device 100 is an air oven, the air inlet side wall 32 is the inner wall of the cooking cavity 33. The device housing 7 includes a door 71 and a shell body 72. The shell body 72 forms an opening 721. The door 71 is rotatably mounted on the opening 721 to open or close the opening 721. The cooking cavity 33 communicates with the opening 721, and at least two cooking plates 34 are removably mounted in the cooking cavity 33 from the opening 721.

[0103] Specifically, such as Figures 4-6As shown, the cooking device 100 is provided with a device housing 7, and the device housing 7 is provided with a door 71 and a shell body 72. A movable opening 721 is formed on one side of the shell body 72. The movable opening 721 is located on the side of the cooking cavity 33 away from the heating element 6 and the fan assembly 5, and the door 71 is rotatably mounted on the movable opening 721 to open or close the movable opening 721. The cooking cavity 33 is connected to the movable opening 721.

[0104] When the user needs to place food into the cooking cavity 33, the door 71 can be pulled to rotate relative to the housing body 72, thereby opening the movable opening 721. This allows the user to place food into the cooking cavity 33 through the movable opening 721. When the cooking device 100 is idle or cooking, the door 71 can be closed to ensure the sealing of the cooking cavity 33, preventing dust from flowing into the cooking cavity 33 and preventing the user from being burned by the high-temperature gas generated during cooking, thus improving the safety of use.

[0105] In addition, the edge of the door 71 can be rotatably connected to the lower edge of the movable opening 721 via a rotating shaft or hinge, so that the door 71 can be rotated downward to open the movable opening 721, allowing the door 71 to remain open under the action of gravity, which is convenient for user operation.

[0106] Furthermore, at least two cooking plates 34 are removably installed in the cooking cavity 33 from the movable opening 721. That is, the cooking plates 34 can be extended into the cooking cavity 33 through the movable opening 721, or they can be pulled out of the cooking cavity 33 through the movable opening 721. Food can be placed on the cooking plates 34 and then extended into the cooking cavity 33 through the cooking plates 34 for cooking.

[0107] When a user needs to cook food, the food can be placed in the cooking plate 34 and then placed into the cooking cavity 33 through the movable opening 721 via the cooking plate 34. At this time, the cooking device 100 can be started. After cooking is completed, the user can pull the cooking plate 34 out of the movable opening 721 and out of the cooking cavity 33 to remove the food. This makes it convenient to use and improves the user experience.

[0108] Furthermore, a tray 8 is provided at the bottom of the cooking cavity 33. The tray 8 is used to temporarily store the grease and other substances produced during cooking. The tray 8 can be pulled out and installed in the cooking cavity 33, so that the user can remove the tray 8 for cleaning after cooking, thus avoiding grease and other substances from contaminating the cooking cavity 33 and making it easy to clean.
