[0039] The following is for reference. Figures 1-9 The cooking apparatus 100 according to an embodiment of the present invention allows high-temperature airflow to enter the food placement basket 3 through the multi-sided airflow duct 12 via the guide structure 4, thereby increasing the gas flow rate into the food placement basket 3 and enabling the food in the entire space to be heated fully and evenly, thus improving the food cooking efficiency. This duct structure is highly versatile and applicable to different types of cooking apparatus 100, and has a simple structure and low installation cost.
[0040] like Figures 1-9 As shown, a cooking device 100 according to an embodiment of the present invention includes: a housing 1 and a food placement basket 3.
[0041] A cooking cavity 21 is formed inside the housing 1, and a cooking fan 211 and a heating element 212 are provided inside the cooking cavity 21.
[0042] Specifically, the cooking device 100 can be an air fryer or other types of cooking devices. The housing 1 is the entire external structure of the cooking device 100. A cooking cavity 21 is formed inside the housing 1. An inner cooking shell 2 can be provided inside the housing 1. The inner cooking shell 2 can be made of thin metal and serves as support and heat insulation. The inner cooking shell 2 can be connected to the housing 1 through structural components. The inner cooking shell 2 can be constructed as a square or cylindrical structure, and the interior forms the cooking cavity 21, which serves as a hot air circulation area. The cooking cavity 21 is equipped with a cooking fan 211 and a heating element 212. The cooking fan 211 is used to drive the airflow to rotate, and the heating element 212 is used to heat the air. The heating element 212 can be constructed as a heating tube. When the heating tube is energized, it will generate heat to heat the surrounding air. The heating element 212 can be fixedly connected to the inner cooking shell 2.
[0043] Furthermore, an installation cavity 11 can be formed between the outer shell 1 and the inner cooking shell 2 for installing the drive component 111. The drive component 111 can be a drive motor, which is detachably connected to the inside of the installation cavity 11 by bolts or other connecting parts. The cooking fan 211 is poweredly connected to the output shaft of the drive component 111. In this way, after the heating element 212 heats the air, the drive component 111 drives the cooking fan 211 to rotate, thereby driving the high-temperature airflow to circulate and heat the food.
[0044] The food placement basket 3 is installed inside the cooking cavity 21. The cooking fan 211 and the heating element 212 are both located on the rear side of the food placement basket 3. That is, the cooking fan 211 and the heating element 212 can be distributed along the front-back direction on the rear side of the food placement basket 3. For example, the cooking fan 211 can be located in front of the heating element 212, and the heating element 212 can also be located in front of the cooking fan 211. The arrangement of the cooking fan 211, the heating element 212, and the food placement basket 3 is varied to adapt to different types of cooking equipment 100. Specifically, the food placement basket 3 is used to hold food, or the food placement basket 3 can be directly pulled out to put food in and out. The food placement basket 3 is detachably connected to the cooking cavity 21, and food can be heated inside the cooking cavity 21.
[0045] An airflow duct 12 is defined between the food placement basket 3 and the inner wall of the cooking cavity 21. The airflow duct 12 and the food placement basket 3 are distributed in a first direction, which intersects with the front-back direction. The first direction can be a horizontal or vertical direction, and the horizontal direction includes the front-back direction and the left-right direction.
[0046] Specifically, the first direction and the front-back direction can be perpendicular to each other. An airflow duct 12 is defined between the outer side of the food placement basket 3 and the inner wall of the cooking cavity 21. The airflow duct 12 can extend in the front-back direction. The airflow duct 12 is used to circulate high-temperature airflow. That is to say, the airflow duct 12 can be distributed between multiple inner walls of the cooking cavity 21 and multiple side walls of the food placement basket 3. In other words, multiple airflow ducts 12 can be set between the inner wall of the cooking cavity 21 and the food placement basket 3 to achieve simultaneous airflow into the food placement basket 3 from multiple directions to heat the food.
[0047] Among them, a guide structure 4 is provided between the food placement basket 3 and the inner wall of the cooking cavity 21. The cooking fan 211 is adapted to drive the high-temperature airflow at the heating element 212 to flow along the guide structure 4 into the airflow duct 12 and then into the food placement basket 3 after passing through the airflow duct 12.
[0048] Specifically, the airflow guide structure 4 is used to deflect and change the airflow direction. The airflow guide structure 4 is located between the cooking cavity 21 and the food placement basket 3. It can be fixedly connected to the inner cooking shell 2. Specifically, the airflow guide structure 4 can be located between the heating element 212 and the food placement basket 3. Driven by the driving element 111, the cooking fan 211 drives the high-temperature hot airflow at the heating element 212 through the guide structure 4, guiding the hot airflow into the airflow duct 12. The hot airflow then enters the food placement basket 3 through the airflow duct 12 to heat the food. Thus, the airflow guide structure 4 achieves airflow rectification, increases airflow velocity, eliminates airflow rotation speed, makes airflow direction more controllable, avoids high-speed and low-speed zones, and thereby improves food cooking efficiency.
[0049] According to the embodiments of the present invention, the cooking device 100 defines an airflow duct 12 between a food placement basket 3 and an airflow duct 12, and provides a guide structure 4 between the two. This allows high-temperature airflow to enter the food placement basket 3 through the multi-sided airflow duct 12, ensuring that the airflow flows into the food placement basket 3 along a stable path. This increases the gas flow rate into the food placement basket 3, allowing for thorough and uniform heating of the food throughout the space, thereby improving food cooking efficiency, increasing the space utilization of the food placement basket 3, and enhancing the performance of the cooking device 100. This duct structure is highly versatile and applicable to different types of cooking devices 100, and it is simple in structure and has low installation cost.
[0050] In some embodiments, the flow guiding structure 4 is formed with a flow guiding groove 41, and the high-temperature airflow at the heating element 212 is adapted to enter the flow guiding groove 41 and flow from the flow guiding groove 41 to the airflow duct 12.
[0051] Specifically, the airflow guiding structure 4 is used to deflect and change the airflow direction. The airflow guiding structure 4 is located between the heating element 212 and the food placement basket 3, such as... Figure 6As shown, the center of the airflow guiding structure 4 is the same as the center of the cooking fan 211. The airflow guiding structure 4 has an airflow guiding groove 41, which can be constructed as a groove or a channel. In this way, the cooking fan 211 can drive the high-temperature hot airflow at the heating element 212 to flow into the airflow guiding groove 41. The hot airflow is guided to the airflow duct 12 through the airflow duct 12 and enters the food placement basket 3 to heat the food.
[0052] Therefore, by setting the guide channel 41, the high-temperature airflow can be better driven into the airflow duct 12, and the airflow can be rectified. In this way, the airflow can be reasonably distributed to ensure that the food is heated more evenly during the cooking process, avoid local overheating or undercooking, reduce heat waste, and improve cooking efficiency.
[0053] In some embodiments, the airflow structure 4 includes a return air region 42 and an airflow guiding region 43. The food placement basket 3 is provided with a first return air hole 311. The first return air hole 311, the return air region 42 and the cooking fan 211 are distributed opposite each other in the front-to-back direction.
[0054] Specifically, the return air zone 42 is used to recirculate the hot airflow in the food basket 3, and the air guide zone 43 is used to guide the direction of the hot airflow, such as... Figure 5 As shown, the food placement basket 3 has a first return air hole 311 on the side near the cooking fan 211, which is used to connect the food placement basket 3 with the return air area 42. The air guiding structure 4 can be constructed as a cover structure. The return air area 42 is located in the central area of the air guiding structure 4, and the air guiding area 43 is located outside the return air area 42. The return air area 42, the first return air hole 311 and the cooking fan 211 are distributed in front and behind each other in the front and back direction. The return air area 42 has a second return air hole 421, which can connect the food placement basket 3 and the air guiding structure 4 along the return air path.
[0055] Furthermore, the first return air hole 311 and the second return air hole 421 are directly opposite each other. In this way, the hot airflow enters the airflow duct 12 through the air guide area 43, and then enters the food placement basket 3 to heat the food. Part of the hot airflow flows in the opposite direction through the first return air hole 311 and the second return air hole 421 to realize the return of the hot airflow. This process is repeated to realize the circulation of the hot airflow and achieve continuous heating of the food.
[0056] And such as Figure 3 and Figure 8 As shown, the small distance between the return air area 42 and the food placement basket 3, or their close proximity, can reduce the return air distance of the hot airflow, thereby increasing the return airflow speed and circulation speed of the hot airflow.
[0057] The first return air hole 311 can be constructed as a round hole, and the second return air hole 421 can be constructed as a round hole, an elliptical hole, etc. There are multiple first return air holes 311 and multiple second return air holes 421. The multiple first return air holes 311 are evenly spaced and distributed on the side wall of the food placement basket 3, and the multiple second return air holes 421 are evenly spaced and distributed in the return air area 42. The multiple first return air holes 311 and multiple second return air holes 421 can be distributed circumferentially or in a square shape. The arrangement is diverse and can be selectively set according to the required return air volume.
[0058] The guide channel 41 includes a first guide sub-channel 411 and a second guide sub-channel 412. The first guide sub-channel 411 is formed in the return air area 42 and distributed around the first return air hole 311. The second guide sub-channel 412 is formed in the air guiding area 43 and connects the first guide sub-channel 411 and the airflow duct 12.
[0059] Specifically, both the first guide slot 411 and the second guide slot 412 are used to change the direction of the hot airflow, such as... Figure 6 As shown, the first guide channel 411 is located on the outer periphery of the return air area 42. The first guide channel 411 can be constructed as an arc-shaped structure and extends around the outer periphery of the first return air hole 311. In this way, the hot airflow in the return air area 42 can be guided through the first guide channel 411 to avoid the hot airflow from being dispersed and causing local overheating.
[0060] Furthermore, the second guide sub-slot 412 is located in the air guiding area 43. The second guide sub-slot 412 can be constructed as a straight structure, and one end of the second guide sub-slot 412 is connected to the first guide sub-slot 411, while the other end of the second guide sub-slot 412 is connected to the airflow duct 12. In this way, the hot airflow in the first guide sub-slot 411 can be guided through the second guide sub-slot 412 and then enter the airflow duct 12, thereby realizing the guidance of hot airflow from the return air area 42 to the airflow duct 12.
[0061] Therefore, through two flow diversions, more hot air can enter the hot air duct 12, which can increase the flow speed of the hot air and deliver more heat to the food placement basket 3. This reduces the circumferential speed of the hot air and forms a loop between the cooking cavity 21 and the food placement basket 3, which can improve the heat utilization rate and improve the heating efficiency and heating effect of the hot air on the food.
[0062] In some embodiments, at least two second guide sub-slots 412 are provided, and the at least two second guide sub-slots 412 are respectively connected to the first guide sub-slots 411. At least two airflow ducts 12 are provided, and the at least two airflow ducts 12 are connected to the at least two second guide sub-slots 412 in a one-to-one correspondence.
[0063] Specifically, at least two second guide sub-slots 412 are respectively connected to the first guide sub-slot 411, that is, the airflow in the first guide sub-slot 411 can flow into at least two second guide sub-slots 412. The number of second guide sub-slots 412 is matched with the number of airflow ducts 12. There are at least two airflow ducts 12, and the at least two airflow ducts 12 are connected to the at least two second guide sub-slots 412 in a one-to-one correspondence. This allows the airflow in each second guide sub-slot 412 to flow along the second guide sub-slot 412 into the airflow duct 12 connected to it, thereby realizing the separate guidance of airflow to at least two airflow ducts 12.
[0064] The second guide channel 412 can be two, three, four, etc., and the corresponding airflow duct 12 can also be two, three, four, etc. In this way, air can be guided by each second guide channel 412 toward each airflow duct 12, so that the airflow flows along a certain path, which can achieve effective airflow diversion, reduce airflow accumulation, improve the uniformity of airflow, and meet the cooking effect of food.
[0065] In some embodiments, the food placement basket 3 has airflow ducts 12 formed on both sides in the first direction, and there are two airflow guiding areas 43 connected to both sides of the return air area 42. The second guide slots 412 of the two airflow guiding areas 43 are connected to the two airflow ducts 12 in a one-to-one correspondence.
[0066] Specifically, such as Figure 4 As shown, two airflow ducts 12 are symmetrically distributed on both sides of the food placement basket 3 along the first direction. Correspondingly, there are two airflow guiding areas 43. The two airflow guiding areas 43 are distributed circumferentially along the return air area 42 and are directly connected to both sides of the return air area 42. Each of the two return air areas 42 is provided with a second airflow guiding sub-slot 412. The two second airflow guiding sub-slots 412 correspond one-to-one with the two airflow ducts 12, and the two second airflow guiding sub-slots 412 are connected to the two airflow ducts 12 one-to-one on the side away from the first airflow guiding sub-slot 411. In this way, the same airflow guiding structure can be formed on both sides of the return air area 42, which is simple in structure and easy to process.
[0067] Therefore, under the rotation of the cooking fan 211, the hot airflow in the return air area 42 can flow into the airflow ducts 12 on both sides through the two air guide areas 43, so that the hot airflow on both sides can enter the food placement basket 3 at the same time, which increases the flow rate of the hot airflow in the food placement basket 3. Moreover, the simultaneous intake of air from both sides can increase the heating area of the food in both the first direction and the front and back directions, thereby improving the heating efficiency of the food.
[0068] In some embodiments, the air guiding region 43 is formed with a plurality of guide ribs 432 extending along a first direction, the guide ribs 432 being used to define a second guide sub-slot 412.
[0069] Specifically, the guide rib 432 has the function of guiding and diverting flow, such as Figure 6 As shown, the guide ribs 432 extend along the first direction, and their extension direction is the same as the flow direction of the hot airflow in the air guiding region 43. A second guide sub-slot 412 is defined between two adjacent guide ribs 432 and / or between the guide rib 432 and the outer wall of the air guiding region 43. The second guide sub-slot 412 extends along the first direction and can divert the airflow from the first guide sub-slot 411, allowing the airflow to flow more evenly along each second guide sub-slot 412. The guide ribs 432 can be three, four, etc. Figure 6 As shown, in this embodiment, there are three guide ribs 432 and four second guide sub-slots 412. The three guide ribs 432 are evenly spaced in the vertical direction, which makes the four second guide sub-slots 412 evenly spaced in the vertical direction, resulting in more uniform hot airflow distribution.
[0070] Therefore, by setting multiple guide ribs 432, the flow path of the hot airflow can be further refined, which helps to distribute the airflow more evenly, improves the control precision of the hot airflow, and thus transfers heat more effectively and prevents disordered diffusion of the airflow, thereby improving cooking efficiency. Furthermore, by guiding and diverting the hot airflow, the circumferential rotation speed of the hot airflow can be reduced, making the airflow speed on the food surface more controllable. Simultaneously, since the airflow does not move from top to bottom or bottom to top, it is less likely to result in uneven uniformity between two layers of food when multi-layer cooking is achieved, ensuring that the food on both layers cooks at the same time. Moreover, the guide ribs 432 can also enhance the structural stability of the airflow guiding area 43, preventing deformation under high temperature or airflow impact. At the same time, it can also reduce noise caused by airflow, providing a quieter cooking environment and better performance.
[0071] In some embodiments, the cooking fan 211 is adapted to rotate in a first rotation direction, and a guide protrusion 413 protruding in a second rotation direction is formed at the connection between the first guide sub-slot 411 and the second guide sub-slot 412. At least a portion of the airflow at the first guide sub-slot 411 is adapted to flow along the guide protrusion 413 to the second guide sub-slot 412. The first rotation direction is opposite to the second rotation direction.
[0072] Specifically, the first direction of rotation can be counterclockwise, and the second direction of rotation can be clockwise, such as... Figure 6As shown, there are two sets of first guide sub-slots 411 and two sets of second guide sub-slots 412. The two sets of first guide sub-slots 411 are distributed opposite each other, and the two sets of second guide sub-slots 412 are distributed opposite each other. The first guide sub-slots 411 are constructed with an arc shape, and the arc radius of the first guide sub-slots 411 gradually increases along the first rotation direction. A guide protrusion 413 is formed at the connection between the first guide sub-slots 411 and the second guide sub-slots 412. The guide protrusion 413 is located at the small arc radius of the first guide sub-slots 411, and the guide protrusion 413 is located at the small arc radius of the first guide sub-slots 411. 3. Protruding along the second rotation direction, that is, protruding towards the connection between the first guide sub-slot 411 and the second guide sub-slot 412. In the specific design, the guide protrusion 413 can be constructed with an inclined surface on the side near the second guide sub-slot 41 and an arc-shaped surface on the side near the first guide sub-slot 411, which is tangentially connected to the first guide sub-slot 411, so that the airflow is smoother. The inclined surface is also conducive to guiding the hot airflow along the inclined surface into the second guide sub-slot 412. The guiding effect is good, and the structure is simple and easy to process.
[0073] Therefore, as Figure 4 , Figure 6 and Figure 8 The arrows indicate the direction of hot airflow. When the cooking fan 211 rotates counterclockwise, the hot airflow is thrown out by centrifugal force and guided through the first guide channel 411. A portion of the hot airflow at the connection between the first guide channel 411 and the second guide channel 412 enters the second guide channel 412 along the guide protrusion 413 and then flows into the airflow duct 12 on one side. A small portion of the hot airflow at the connection between the first guide channel 411 and the second guide channel 412 flows to the first guide channel 41 on the other side, then enters the second guide channel 412 on the other side through the guide protrusion 413 on the other side, and then enters the airflow duct 12 on the other side. This can achieve the diversion of hot airflow and direct it to the airflow ducts 12 on both sides, realizing air intake on both sides of the food placement basket 3. The diversion effect is very good, which is conducive to transferring a large amount of heat to the surface of the food and improving the cooking effect.
[0074] In some embodiments, the first direction is the left-right direction of the cooking device 100, and / or the first direction is the up-down direction of the cooking device 100. That is, the first direction can be set to the left-right direction of the cooking device 100, the first direction can be set to the up-down direction, that is, the first direction can be set to a direction perpendicular to the front-back direction, and the first direction can be the up-down direction and the front-back direction of the cooking device 100.
[0075] Specifically, when the first direction is the left-right direction of the cooking device 100, such as... Figures 2-4As shown, the heating element 212 and the cooking fan 211 are located sequentially on the rear side of the food placement basket 3, and the drive unit 111 is located in the rear area of the cooking device 100. The airflow duct 12 and the food placement basket 3 are distributed in the left and right directions, that is, the airflow duct 12 is located on the left and right sides of the food placement basket 3 respectively. In this way, the hot airflow at the heating element 212 located on the rear side enters the airflow duct 12 on the left and right sides through the air guide area 43, flows in the front and back direction and flows into the food placement basket 3 in the left and right direction, realizing the left and right side air intake. In the food placement basket 3, it flows from front to back to the first return air hole 311 and enters the return air area 42. This cycle is repeated to realize the circulation of hot airflow. The flow direction of the hot airflow is regular and the flow rate is relatively uniform, which can improve the utilization rate of hot airflow.
[0076] When the first direction is the up-down direction of the cooking device 100, such as... Figures 2-4 As shown, the heating element 212 and the cooking fan 211 are located sequentially on the rear side of the food placement basket 3, and the drive unit 111 is located in the rear area of the cooking device 100. The airflow duct 12 and the food placement basket 3 are distributed in the vertical direction, that is, the airflow duct 12 is located on the upper and lower sides of the food placement basket 3 respectively. In this way, the hot airflow at the heating element 212 located on the rear side enters the airflow duct 12 on the upper and lower sides through the air guide area 43, flows in the front-to-back direction and flows into the food placement basket 3 in the vertical direction, realizing the upper and lower side air intake. In the food placement basket 3, it flows from front to back to the first return air hole 311 and enters the return air area 42. This cycle is repeated to realize the circulation of hot airflow. The flow direction of the hot airflow is regular and the flow rate is relatively uniform, which can improve the utilization rate of hot airflow.
[0077] Furthermore, when the first direction is the up-down and left-right directions of the cooking device 100, the hot airflow at the heating element 212 located at the rear can enter the airflow ducts 12 on the upper and lower sides and the left and right sides through the air guide area 43, and then flow in the front-back direction and flow into the food placement basket 3 in the up-down and left-right directions respectively, so as to realize the simultaneous air intake on the upper and lower sides and the left and right sides. In the food placement basket 3, it flows from front to back to the first return air hole 311 and enters the return air area 42. This cycle is repeated to realize the circulation of hot airflow. The hot airflow has a regular flow direction and a relatively uniform flow rate, which can improve the utilization rate of hot airflow.
[0078] In addition, it should be noted that the cooking fan 211 and the heating element 212 can both be located on top of the food placement basket 3.
[0079] like Figures 7-8As shown, in another embodiment, the cooking fan 211, the heating element 212, and the food placement basket 3 are distributed along the vertical direction, and the heating element 212 and the cooking fan 211 are located at the top of the food placement basket 3 in sequence, and the driving element 111 is located in the upper region of the cooking device 100, that is, the airflow guide structure 4 is located at the top of the cooking cavity 21. At this time, the first direction can be the front-back direction and / or the left-right direction, that is, the airflow ducts 12 are located on the left and right sides and / or the front and back sides of the food placement basket 3 respectively. In this way, the hot airflow at the heating element 212 at the top enters the airflow ducts 12 on the upper and lower sides and / or the left and right sides through the airflow guide area 43, and flows along the vertical direction and flows into the food placement basket 3 along the front-back direction and the left and right direction respectively, realizing the simultaneous air intake on the upper and lower sides and / or the left and right sides. In the food placement basket 3, it flows from bottom to top to the first return air hole 311 and enters the return air area 42. This cycle is repeated to realize the circulation of hot airflow. The flow direction of the hot airflow is regular and the flow rate is relatively uniform, which can improve the utilization rate of hot airflow.
[0080] It should be noted that the cooking device 100 in this embodiment is a top-discharge cooking device, with the food support 34 perpendicular to the rotation axis of the cooking fan 211. This means that for the hot airflow to completely penetrate the food, the airflow duct 12 will experience greater resistance than a side-discharge cooking device 100. This type of cooking device 100 requires a cooking fan 211 with a larger blade diameter and a more powerful motor, while maintaining a consistent overall duct structure to achieve optimal food cooking under top-discharge conditions. Furthermore, the viewing window in a top-discharge cooking device 100 can be located on the side of the device.
[0081] In some embodiments, the food placement basket 3 includes a return air sidewall 31 and two air inlet sidewalls 32. The return air sidewall 31 is distributed opposite to the cooking fan 211 in the front-back direction, and the return air sidewall 31 is provided with a first return air hole 311. The two air inlet sidewalls 32 are distributed opposite to each other in the first direction. An airflow duct 12 is formed between the air inlet sidewall 322 and the inner wall of the cooking cavity 21. The air inlet sidewall 32 is provided with an air inlet hole 321 that communicates with the airflow duct 12.
[0082] Specifically, such as Figure 5As shown, the food storage basket 3 is constructed as a square frame and has a return air sidewall 31 and two air inlet sidewalls 32. The return air sidewall 31 is located at the rear of the food storage basket 3, and the two air inlet sidewalls 32 are located at the sides of the food storage basket 3. The return air sidewall 31 and the cooking fan 211 are directly opposite each other in the front-back direction, and the two air inlet sidewalls 32 are relatively distributed in the first direction. In actual design, the two air inlet sidewalls 32 can be directly opposite each other in the first direction, which is conducive to symmetrical air intake at the two air inlet sidewalls 32. The first return air hole 311 is located on the return air sidewall 31, and the air inlet sidewall 32 is provided with an air inlet hole 321. Through the air inlet hole 321, the airflow duct 12 can be connected to the inside of the food storage basket 3 to realize the side air intake of the food storage basket 3. Then, through the first return air hole 311, the airflow flows into the guide structure 4 through the return air sidewall 31 for circulation.
[0083] Therefore, the airflow direction is as follows Figure 4 and Figure 8 As indicated by the arrows, the hot airflow from the two air guide zones 43 enters the airflow ducts 12 on both sides, flows in the front-to-back direction, and then enters the food placement basket 3 through the air inlets 321 on both sides, so that the hot airflow evenly fills the food placement basket 3 from both sides, improving the uniformity and efficiency of air intake.
[0084] In some embodiments, the air inlet sidewall 32 is provided with a plurality of air inlet holes 321, the aperture of the plurality of air inlet holes 321 being configured to gradually increase in the direction away from the cooking fan 211.
[0085] The air inlet 321 can be constructed as a square or elongated hole, etc. Figure 5 As shown, there are multiple air inlets 321, which are spaced apart in the front-to-back direction. For example, the multiple air inlets 321 can be evenly spaced apart in the front-to-back direction. In particular, the diameter of the multiple air inlets 321 gradually increases in the direction away from the cooking fan 211. This arrangement can increase the resistance of the hot airflow near the cooking fan 211, thereby reducing the airflow near the cooking fan 211. It can also reduce the resistance of the hot airflow away from the cooking fan 211, thereby increasing the airflow away from the cooking fan 211. This achieves uniform airflow across the entire surface of the two air inlet sidewalls 32, which can compensate for the uneven airflow caused by the continuous decrease in the speed of the hot airflow during flow. This improves the airflow efficiency from the airflow duct 12 to the food placement basket 3, improves the cooking efficiency of the food, and has a simple and ingenious structure. Furthermore, depending on the equipment, air inlets 321 can be provided on the side wall of the food placement basket 3 (near the cooking fan 211) and on the front side of the side wall of the food placement basket 3 to adjust the air intake at different locations to better meet the air intake requirements.
[0086] In addition, for the top-vented cooking device 100, multiple air inlets 321 are evenly spaced apart in the vertical direction.
[0087] In some embodiments, the food placement basket 3 includes a return air sidewall 31, an air inlet sidewall 32, and two air guide sidewalls. The air inlet sidewall 32, the return air sidewall 31, and the cooking fan 211 are distributed opposite each other in the front-back direction. The return air sidewall 31 is provided with a first return air hole 311. The two air guide sidewalls are distributed opposite each other in the first direction. The airflow duct 12 is formed between the air guide sidewall and the inner wall of the cooking cavity 21. The air inlet sidewall 32 is provided with an air inlet hole 321 that communicates with the airflow duct 12.
[0088] Specifically, such as Figure 4 As shown, the food storage basket 3 has a return air sidewall 31, two air guide sidewalls, and an air inlet sidewall 32. The return air sidewall 31 can be located at the rear of the food storage basket 3, the two air guide sidewalls are located at the sides of the food storage basket 3, and the air inlet sidewall 32 is located at the front of the food storage basket 3. The air inlet sidewall 32, the return air sidewall 31, and the cooking fan 211 are distributed opposite each other in the front-back direction. The two air guide sidewalls are distributed opposite each other in the first direction. In actual design, the two air guide sidewalls can be distributed opposite each other in the first direction, which is conducive to the two air guide sidewalls symmetrically intake air towards the air inlet sidewall 32. The first return air hole 311 is located on the return air sidewall 31, and the air inlet sidewall 32 is provided with an air inlet hole 321. Through the air inlet hole 321, the airflow in the airflow duct 12 can enter the interior of the food storage basket 3 from the front, realizing the front intake of the food storage basket 3. Then, through the first return air hole 311, it passes through the return air sidewall 31 and flows into the guide structure 4 for circulation.
[0089] Therefore, the airflow direction is as follows Figure 4 As indicated by the arrows, the hot airflow from the two air guide zones 43 enters the airflow ducts 12 on both sides and flows from back to front to the front air intake sidewall 32. It then enters the food placement basket 3 through the air intake hole 321 to heat the food.
[0090] Furthermore, the food storage basket 3 can be configured to receive air from both the side and the front, allowing hot air to flow into the food storage basket 3 from multiple sides, thereby improving the uniformity and efficiency of the air intake.
[0091] In some embodiments, a food placement cavity 33 is formed inside the food placement basket 3, and a food support member 34 is provided inside the food placement cavity 33.
[0092] Specifically, such as Figure 5 As shown, the shape of the food placement cavity 33 matches that of the food placement basket 3. The food placement cavity 33 has an open opening for placing food through the open opening. The open opening of the food placement cavity 33 faces upward. The food placement cavity 33 is provided with a food support 34 for placing and supporting food. The food support 34 can be a baking tray, frying tray, etc. The food support 34 can be fixedly connected to the food placement cavity 33. When in use, the food to be cooked is placed on the food support 34 for cooking.
[0093] There are at least two food supports 34, and the at least two food supports 34 are spaced apart in the vertical direction. Food can be placed on the at least two food supports 34 at the same time, which can increase the amount of food that can be cooked and the cooking of multiple foods.
[0094] Furthermore, the spacing between multiple food supports 34 can be the same, thus maximizing the use of limited space and allowing multiple food supports 34 to be placed simultaneously to cook more food, improve cooking efficiency, save time and energy, and make reasonable use of the space in the food placement cavity 33. In the design, the flow of hot air between each layer ensures that the food in each layer is heated evenly. The food supports 34 can be designed to be detachable and adjustable to adapt to different amounts and types of food, and the shape of the food supports 34 can be matched with the space in the food placement cavity 33, such as square or round, and is easy to disassemble and clean, maintaining the hygiene of the air fryer.
[0095] Among them, such as Figure 3 , Figure 5 and Figure 8 As shown, there are two food supports 34, and the food supports 34 can also be set to three, four, etc.
[0096] Each food support 34 has a ventilation hole 341, and an air inlet 321 communicates with the ventilation hole 341. Specifically, ventilation can be achieved on the upper and lower sides of the food support 34 through the ventilation hole 431. Figure 5 As shown, there are multiple ventilation holes 341, which are evenly spaced apart and distributed on the food support 34. The ventilation holes 341 can be constructed as elongated holes. The air inlet 321 is adapted to connect to the top and / or bottom of the food support 34. In actual design, the air inlet 321 can connect to the top of the food support 34, or to the bottom of the food support 34, or simultaneously to both the top and bottom of the food support 34. The configuration is diverse and can be set according to actual air intake requirements. In this embodiment, the air inlet 321 connects to both the top and bottom of the food support 34. In this way, hot air enters the food placement cavity 33 through the airflow duct 12 via the air inlet 321, and the hot air in the food placement cavity 33 can flow up and down through the ventilation holes 341, simultaneously heating both the top and bottom sides of the food and improving the heating efficiency of the food.
[0097] In some embodiments, the cooking device 100 further includes a viewing window 15 disposed on the top of the housing 1, with the first direction being the left-right direction, and the food placement basket 3 is adapted to allow air to enter along the first direction or from the front.
[0098] Specifically, the viewing window 15 is located on the top of the housing 1, allowing the user to observe the cooking effect of the food in the cooking cavity 21 through the viewing window 15 on the top of the housing 1. When the first direction is left-right, that is, the airflow ducts 12 are distributed on the left and right sides of the food placement basket 3, side air intake of the food placement basket 3 can be achieved. In addition, when the airflow ducts 12 can lead to the front of the food placement basket 3, air intake from the front of the food placement basket 3, the food support 34 is parallel to the rotation axis of the cooking fan 211, and the airflow ducts 12 are not provided on the top of the food placement basket 3, a complete viewing window 15 can be provided on the top of the housing 1, providing more space for observing the food cooking process to meet the user's visualization needs, and the overall structure of the cooking device 100 is safe and efficient.
[0099] Therefore, through the above settings, the airflow can be directed to multiple airflow channels 12 through the airflow guide structure 4, and the airflow can be drawn from multiple airflow channels 12 toward the food placement basket 3, which can improve the heating uniformity and cooking efficiency of the food, and provide a viewing window 15 for users to observe the cooking process, thus solving the problem of the viewing window 15 damaging the airflow channels 12.
[0100] Furthermore, the viewing window of the top-vented cooking device 100 can be located on the side of the cooking device 100.
[0101] In some embodiments, the front side of the housing 1 is provided with an opening 13, and the food placement basket 3 is adapted to extend into or out of the cooking cavity 21 in the front-back direction from the opening 13.
[0102] Specifically, the front side of the casing 1 is the user area, such as... Figure 1 and Figure 3 As shown, a movable opening 13 is formed on the front side of the housing 1 for the food placement basket 3 or the food support 34 to extend or retract. That is, the food support 34 can be removed along with the food placement basket 3, or the food support 34 can be removed and placed separately. The movable opening 13 is constructed as a square hole, and the size of the square hole is larger than the size of the food placement basket 3. In this way, the user can extend the food placement basket 3 into the cooking cavity 21 in the front-to-back direction through the movable opening 13. After cooking, the food placement basket 3 or the food support 34 can be removed from the movable opening 13. By providing a movable opening 13 on the front side, it is convenient for the user to operate the cooking device 100.
[0103] The movable opening 13 is equipped with a cover plate, which can be rotatably connected to the outer structure of the movable opening 13, or snap-fitted to it, etc. Figure 2 and Figure 3 As shown, a handle 14 is provided on the outside of the food placement basket 3 or the cover. The user can operate the handle 14 to extend the food placement basket 3 into or out of the cooking cavity 21 in the front-back direction, or to open or close the movable opening 13 of the cover, thereby ensuring the safety of the cooking process.
[0104] In some embodiments, a cooling fan 112 is also provided in the mounting cavity 11. The cooling fan 112 is arranged coaxially with the cooking fan 211, and the driving member 111 is used to drive the cooling fan 112 and the cooking fan 211 to rotate.
[0105] Specifically, such as Figure 3 , Figure 4 and Figure 8 As shown, in the front-to-back direction of the cooking device 100, a heating element 212, a cooking fan 211, a cooling fan 112, and a driving element 111 are sequentially distributed from the food placement basket 3 to the driving element 111. A mounting cavity 11 is provided inside the housing 1, spaced apart from the cooking cavity 21. The cooling fan 112 and the driving element 111 are located within the mounting cavity 11. The cooking fan 211 and the cooling fan 112 are spaced apart along the same axis and are both connected to the output shaft of the driving element 111. The driving element 111 is a drive motor; the rotation of the drive motor drives the cooling fan 112 and the cooking fan 211 to rotate simultaneously. The cooking fan 211 drives the hot airflow to circulate, and the cooling fan 112 drives the airflow to rotate, thus achieving heat dissipation of the cooking device 100. During long-term operation or high-power operation, this prevents the electronic components and heating element 212 of the cooking device 100 from overheating, thereby avoiding damage and improving product safety and service life.
[0106] It should be noted that, for example Figure 9 The exploded view shown is of the cooking device 100. The housing 1 includes a top outer shell 16, a top support member 17, a bottom outer shell 18, and a tail outer shell 19. The outer shell 16, the top support member 17, the bottom outer shell 18, and the tail outer shell 19 are connected to form the housing 1. An inner cooking shell 2 is connected inside the housing 1. The inner cooking shell 2 includes a cooking shell top plate 22, a cooking shell side wall 23, and a cooking shell bottom plate 24. The cooking shell top plate 22, the cooking shell side wall 23, and the cooking shell bottom plate 24 are connected to form the inner cooking shell 2. A cooking cavity 21 is formed inside the inner cooking shell 2. A food placement basket 3 is located inside the inner cooking shell 2. A support member 5 is also provided between the housing 1 and the inner cooking shell 2. The rear side wall of the support member 5 has an installation position for installing a flow guide structure 4. The tail outer shell 19 has an installation space for installing a drive member 111, a cooling fan 112, a cooking fan 211, etc.
