Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen equipment, and in particular to a visual cooking device. BACKGROUND

[0002] Most existing frying and roasting equipment is provided with a hot air circulation assembly on the top of a container. The hot air circulation assembly includes a heating element, a fan blade, and a motor for driving the fan blade to rotate. The heating element generates heat, and the fan blade rotates under the driving action of the motor and blows the heat generated by the heating element into the container to heat the food.

[0003] Such products cannot be designed as large-area visual structures because the upper part of the air fryer body needs to be designed according to the hot air circulation assembly and some electrical components, and can only be designed with a local visual window on the side of the body or with a glass pot to meet the need of observing the inside of the cooking cavity. For example, a patent with publication number CN212089287U discloses a visual multifunctional air roasting and frying pot. The pot includes a heating base for generating hot air, a placing set for loading food materials, and a cover assembly detachably arranged on the heating base. The placing set includes a first roasting assembly and a second roasting assembly which are used separately with the heating base. The cover assembly is provided with a roasting cavity, and the heating base is provided with a heating cavity. The first roasting assembly is located between the heating cavity and the roasting cavity, and the heating cavity is communicated with the roasting cavity through a ventilation structure on the first roasting assembly to form an internal circulation hot air duct. The heating base includes a heating assembly for blowing circulating hot air to the hot air duct and heating the second roasting assembly, and the heating assembly is located below the placing set.

[0004] In the above scheme, the cover assembly includes a visual cover made of transparent material. Although the visual cover can solve the problem of visibility, it is only supported on the top of the base shell without any sealing connection structure, which can easily cause the heat in the cavity to overflow from the gap between the visual cover and the top of the base shell, affecting the overall hot air circulation effect and the heating effect of the food, and there is a risk of scalding. In addition, the hot air in the roasting cavity returns to the heating cavity through the second ventilation hole under the suction action of the upper fan, and the oil and oil fume generated during the cooking process of the food will also enter the heating cavity along with the hot air, and adhere to the lower fan and the drive motor along the hole where the motor shaft of the drive motor is located, causing the oil fume to backflow and contaminate the core components such as the lower fan and the drive motor. Since the heating pipe, the upper fan, the lower fan, and the motor are fixed compactly in the base shell, it is extremely inconvenient to disassemble them, which makes it difficult to completely clean the oil stains. SUMMARY

[0013] Optionally, a wind guide cover is arranged in the sandwich cavity and covers the lower pot body, a hot air passage is formed between the wind guide cover and the lower pot body and communicates with the sandwich cavity, the first heating element is arranged in the hot air passage and corresponds to the wind guide hole, so that the hot air flow is drawn into the cooking container through the wind guide hole by the wind circulation assembly to heat the food.

[0014] Optionally, a handle is arranged on the body, the handle and the base are fixedly connected by a locking element, and a positioning and cooperating structure is arranged between the handle and the transparent shell.

[0015] Optionally, the positioning and cooperating structure comprises a mounting block arranged on the transparent shell and a positioning block arranged on the handle, and the mounting block is provided with a mounting groove for the positioning block to extend into.

[0016] In summary, the present application has at least the following beneficial effects: 1. The air flow generated by the air circulation assembly flows into the interlayer cavity, and the first heating element heats the air flow passing through it. The hot air flow enters the cooking container through the air guide hole under the suction of the fan, heats the food, and the fan draws the hot air flow in the cooking container from bottom to top to the air circulation assembly, forming a three-dimensional circulating air flow that penetrates the entire food from bottom to top, ensuring that heat can uniformly wrap the surfaces of the food, making the food more evenly heated. Since the first heating element is placed in the interlayer cavity, it only heats the air flowing through the interlayer cavity and does not directly contact the splashed oil and food debris. Compared with the heating element of the existing air fryer located above or below the pot, the first heating element is physically isolated from the oil, greatly reducing the cleaning difficulty of the first heating element. After cooking, the head is removed, and the cooking container is taken out from the opening at the top of the body. The air circulation assembly and the first heating element are exposed to the outside, making it easy to clean the inside of the body, the first heating element, and the air circulation assembly. The upper part of the cooking container is transparent, forming a double-layer transparent structure with the transparent shell, which can achieve full-viewing effect. Users can observe the coloring of food and the cooking progress from the side without any dead angles, fundamentally solving the problem of instantaneous heat loss caused by frequent opening of the head, ensuring cooking efficiency and saving energy. It can also flexibly adjust the time or temperature according to real-time conditions, greatly reducing the risk of burning or undercooking, and significantly improving the success rate of cooking. Moreover, the transparent shell and the cooking container form a closed interlayer cavity, which not only ensures the airflow path but also effectively isolates the high-temperature area inside the cooking container from the external environment, reducing the risk of burns when users touch it. The upper part of the cooking container and the transparent shell are made of high-temperature-resistant transparent materials, ensuring the stability and safety of the materials in a long-term high-temperature working environment, avoiding the risk of deformation, melting, or releasing harmful substances, and significantly improving the structural reliability and safety of the equipment under high-temperature working conditions.

[0017] 2. The connecting part of the transparent shell is clamped between the inner container and the outer shell, forming a double-direction clamping structure, which can further fix the transparent shell and prevent it from tilting upward or collapsing downward due to vibration or accidental touch. The overlapping structure of the inner container can further compact the bonding surface of the connecting part, the inner container, and the base, preventing bonding problems caused by slight deformation of the connecting part, ensuring the airtightness of the interlayer cavity, and preventing hot air from escaping through the gap.

[0018] 3. The outer shell and inner liner are fixedly connected by locking components. After the outer shell and inner liner clamp the connecting part of the transparent shell, the locking components can apply mechanical preload to firmly lock the inner liner and the outer shell, thereby generating uniform pressure on the connecting part in the middle, and thus fixing the transparent shell and the base together. In addition, the external force of the locking components can further eliminate the fit gaps between the outer shell, the connecting part, and the inner liner, so that the three form a whole when working, avoiding wear or local stress caused by loose parts, and greatly improving mechanical strength and stability.

[0019] 4. A rubber gasket is installed between the inner liner and the connecting part, covering the connecting part. When the locking device is tightened, the rubber gasket will elastically deform, filling any unevenness or gaps that may exist between the transparent shell and the inner liner. This improves the sealing between the transparent shell and the inner liner, preventing hot air in the interlayer cavity from escaping through the gaps between the transparent shell and the inner liner. This ensures that all airflow in the interlayer cavity participates in effective circulation, thereby guaranteeing the food cooking effect and thermal efficiency. At the same time, the rubber gasket acts as a buffer, ensuring that the inner liner does not directly apply concentrated hard impact to the transparent shell, greatly improving the reliability and safety of the transparent shell in long-term use.

[0020] 5. The cooking container includes an upper pot body and a lower pot body that is detachable from the upper pot body. The upper pot body is made of a high-temperature resistant transparent material, which, together with the transparent shell, forms a double-layer visible structure, ensuring 360-degree observation without blind spots. The lower pot body can be made of a high-temperature resistant plastic material, which is more resistant to impacts and less prone to breakage. While ensuring visibility, it improves the structural reliability and safety of the equipment. After cooking, remove the cooking container from the opening at the top of the machine to avoid the inconvenience of operating in the narrow space inside the machine. This allows for easy cleaning of the inside of the machine and the first heating element. Furthermore, the upper and lower pots can be easily separated, fully exposing the oil stains and allowing for thorough cleaning of both the upper and lower pots. By placing the air guide holes on the side wall of the lower pot, the hot airflow generated by the first heating element enters the cooking container through the air guide holes under the suction of the fan. The hot air forms a surrounding airflow that wraps around the sides of the food the moment it enters, and combined with the suction force of the top fan, it forms a three-dimensional circulation from bottom to top, thereby improving the heating uniformity of the food.

[0021] 6、The sandwich cavity is provided with a wind guide cover arranged on the lower pot body, a hot air passage is formed between the wind guide cover and the lower pot body and communicated with the sandwich cavity, the first heating member is arranged in the hot air passage and corresponds to the air guide hole, so that the hot air flow is drawn into the cooking container by the air circulation assembly through the air guide hole to heat the food, the visibility of the whole is not affected while the hot air circulation is not affected; the first heating member is arranged in the wind guide cover, the heat generated by the first heating member is highly concentrated and efficiently utilized, and the first heating member corresponds to the air guide hole of the side wall of the lower pot body, the heat is directly used for heating the air flowing through the hot air passage, the heat is almost wasted by the air and is all used for cooking, avoiding the energy waste and component aging caused by the upward loss of part of the heat to the machine head in the traditional top heating.

[0033] The present application will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely specific illustrations of the present application, and their purpose is to enable those skilled in the art to better understand the technical solutions of the present application, and should not be regarded as limitations on the present application.

[0034] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] This application discloses a visual cooking device, such as... Figure 1 and Figure 2 As shown, the device includes a body 1, a head 2 covering the body 1, and a cooking container 3 located inside the body 1. The head 2 is equipped with a downward-opening reflector 21 and a wind circulation component 22 located inside the reflector 21. The wind circulation component 22 includes a fan 221 with its own motor. The cooking container 3 is made of a high-temperature resistant transparent material at least at the top, and has an air guide hole 321 at the bottom. The body 1 includes a base 13 with an upward opening and a high-temperature resistant transparent shell 14 located above the base 13. The transparent shell 14 is sealed to the base 13, and the transparent shell 14 and the cooking container 3 form a sandwich cavity 8. A first heating element 4 is provided in the sandwich cavity 8.

[0036] The air flow generated by the fan 221 flows into the interlayer cavity 8 under the guidance of the reflector 21, and the first heating element 4 heats the air flow passing through it. The hot air flow enters the cooking container 3 through the air guide hole 321 under the suction of the fan 221, heats the food, and the fan 221 sucks the hot air flow in the cooking container 3 from bottom to top to the fan 221, forming a three-dimensional circulating air flow through the entire food from bottom to top, ensuring that heat can uniformly wrap around all surfaces of the food, making the food more evenly heated.

[0037] Since the first heating element 4 is placed in the interlayer cavity 8, it only heats the air flowing through the interlayer cavity 8 and does not directly contact the splashed oil and food debris. Compared with the heating element of the existing air fryer located above or below the pot, which is directly exposed to the splashed oil, the first heating element 4 is physically isolated from the oil, greatly reducing the difficulty of cleaning the first heating element 4. After cooking, the head 2 is removed, and the cooking container 3 is taken out from the opening at the top of the body 1. The fan 221 and the first heating element 4 are exposed and can be easily cleaned inside the body 1, the first heating element 4, and the fan 221.

[0038] The cooking container 3 is at least partially transparent, forming a double-layer transparent structure with the transparent shell 14, which can achieve a full-view effect. Users can observe the browning of food and the cooking progress from the side without any dead angles, fundamentally solving the problem of instantaneous heat loss caused by frequent opening of the head 2, ensuring cooking efficiency and saving energy. It can also flexibly adjust the time or temperature according to real-time conditions, greatly reducing the risk of burning or undercooking, and significantly improving the success rate of cooking.

[0039] Moreover, the transparent shell 14 and the cooking container 3 form a closed interlayer cavity 8, which not only ensures the air flow path but also effectively isolates the high-temperature area inside the cooking container 3 from the external environment, reducing the risk of burns from touching hot surfaces. The upper part of the cooking container 3 and the transparent shell 14 are made of high-temperature-resistant transparent materials such as heat-resistant glass or high-temperature polycarbonate, ensuring the stability and safety of the materials in a long-term high-temperature working environment, avoiding the risk of deformation, melting, or releasing harmful substances, and significantly improving the structural reliability and safety of the equipment under high-temperature working conditions.

[0040] As a feasible implementation, in combination with Figure 3The bottom of the transparent shell 14 is provided with an inwardly extending connecting portion 141, and the connecting portion 141 is provided with a downwardly extending surrounding edge 142. The base 13 is covered outside the surrounding edge 142 or located inside the surrounding edge 142. The downwardly extending surrounding edge 142 can realize quick positioning and prevent the transparent shell 14 from deviating in the horizontal direction. The top of the base 13 abuts against the connecting portion 141, which clearly defines the vertical mounting position of the transparent shell 14 and the base 13, avoids stress concentration or looseness caused by excessive downward pressing of the transparent shell 14, and thus realizes accurate positioning and convenient assembly. The accurate positioning can ensure the reliability of the sealing effect, prevent high-temperature gas from overflowing from the connecting gap between the transparent shell 14 and the connecting portion 141, reduce the risk of user scalding, and ensure the heating efficiency.

[0041] The connecting portion 141 and the surrounding edge 142 form an L-shaped support, which greatly enhances the strength of the bottom edge of the transparent shell 14. When the head 2 is covered on the body 1, the downward pressure is transmitted to the base 13 through the transparent shell 14 and the connecting portion 141 and the surrounding edge 142, avoiding stress concentration at the weak part of the transparent shell 14, and thus improving the structural strength and stability of the transparent shell 14.

[0042] The base 13 includes an outer shell 131 and an inner container 132. The connecting portion 141 of the transparent shell 14 is clamped between the inner container 132 and the outer shell 131 and is sealingly connected with them. The base 13 is covered outside the surrounding edge 142 of the transparent shell 14. The top of the inner container 132 extends outwardly along the edge and is arranged above the connecting portion 141, forming a structure of double-direction clamping up and down, which can further fix the transparent shell 14 and avoid the situation that the transparent shell 14 is raised upward or collapses downward due to vibration or accidental touch. The clamping structure of the top edge of the inner container 132 can further compact the bonding surface of the connecting portion 141, the inner container 132 and the base 13, avoid the combination problem caused by slight deformation of the connecting portion 141, ensure the airtightness of the sandwich cavity 8, and prevent hot gas from overflowing through the gap.

[0043] The outer shell 131 and the inner container 132 are both arranged in an upwardly open U shape. The inner container 132 is made of a high-temperature-resistant metal material such as stainless steel, which can withstand high temperature for a long time without deformation or melting. The surface of the metal inner container 132 has high flatness, and the bonding surface with the connecting portion 141 of the transparent shell 14 can realize tight sealing, effectively preventing hot gas in the sandwich cavity 8 from overflowing from the connecting gap. The outer shell 131 is made of plastic material, which can form a heat shield barrier through its low heat conduction, so that the external surface temperature of the base 13 is controlled within a safe range, avoiding user scalding caused by accidental touch of the base 13 during operation.

[0044] The outer shell 131 and the inner container 132 are fixedly connected through a locking piece. After the outer shell 131 and the inner container 132 sandwich the connecting part 141 of the transparent shell 14, the locking piece can exert a mechanical pre-tightening force to tightly lock the inner container 132 and the outer shell 131, thereby generating uniform pressure on the intermediate connecting part 141, and further fixing the transparent shell 14 and the base 13 together. In addition, the external force of the locking piece can further eliminate the fitting gap of each part of the outer shell 131, the connecting part 141 and the inner container 132, so that the three form a whole during work, avoiding wear or local stress caused by loose parts, and greatly improving the mechanical strength and stability. It should be noted that the bottom of the outer shell 131 is provided with at least one connecting block 133, and the outer shell 131 and the connecting block 133 are provided with a through counterbore, and a fixing rod 134 with a threaded hole is arranged in the counterbore. The inner container 132 is provided with a limiting hole corresponding to the threaded hole, and a locking piece such as a bolt is arranged between the limiting hole and the threaded hole, thereby improving the connection stability between the outer shell 131 and the inner container 132. The bottom of the inner container 132 is provided with a positioning part circumferentially along the limiting hole. The positioning part is in the shape of a circular truncated cone, and the diameter of the top of the positioning part is greater than the diameter of the bottom of the positioning part. The fixing rod 134 penetrates through the counterbore and abuts against the inner container 132, and the positioning part extends into the threaded hole, so as to position the fixing rod 134.

[0045] The inner container 132 and the connecting part 141 are provided with a rubber pad 17. The rubber pad 17 covers the connecting part 141. When the locking piece is locked, the rubber pad 17 will be elastically deformed, and can fill the possible unevenness and gap between the transparent shell 14 and the inner container 132, thereby improving the sealing between the transparent shell 14 and the inner container 132, preventing the hot air in the interlayer cavity 8 from overflowing from the gap between the transparent shell 14 and the inner container 132, ensuring that all the air volume in the interlayer cavity 8 participates in effective circulation, thereby guaranteeing the food cooking effect and thermal efficiency. At the same time, as a buffer, the rubber pad 17 ensures that the inner container 132 does not directly exert concentrated hard impact on the transparent shell 14, greatly improving the reliability and safety of the transparent shell 14 in long-term use.

[0046] In combination Figure 4 The cooking container 3 includes an upper pot body 31 and a lower pot body 32 detachable from the upper pot body 31. The upper pot body 31 is made of a transparent material resistant to high temperature, and cooperates with the transparent shell 14 to form a double-layer visible structure, which can ensure a 360-degree observation effect without dead angle. The lower pot body 32 can be made of a high-temperature-resistant plastic material, which is more resistant to impact and less likely to break. Under the premise of ensuring visibility, the structural reliability and safety of the equipment are improved.

[0047] After cooking, the cooking container 3 is taken out from the opening at the top of the body 1, avoiding the inconvenience of operating in the narrow space inside the body 1, and the inside of the body 1 and the first heating element 4 can be easily cleaned; and the upper pot body 31 and the lower pot body 32 can be easily separated, completely exposing the oil stain dead angle, and the upper pot body 31 and the lower pot body 32 can be thoroughly cleaned.

[0048] The air guide hole 321 is arranged on the side wall of the lower pot body 32, so that the hot air flow generated by the first heating element 4 enters the cooking container 3 under the suction action of the fan 221, and the hot air can form a surrounding air flow wrapping the side of the food at the moment of entering, and combined with the suction force of the top fan 221, a three-dimensional circulation from bottom to top is formed, thereby improving the heating uniformity of the food.

[0049] In the embodiment, the upper pot body 31 is cylindrically arranged, and the bottom thereof is provided with an opening to communicate the upper pot body 31 with the lower pot body 32. In other embodiments, the bottom of the upper pot body 31 is provided with a bottom wall, and a plurality of air inlet holes are arranged on the bottom wall of the upper pot body 31. The bottom wall can be used to hold food, and the oil generated by the food during cooking can also drip downward through the air inlet holes.

[0050] In combination Figure 5 The bottom of the upper pot body 31 is provided with a mounting step 311, which is integrally formed with the upper pot body 31. The lower pot body 32 is arranged outside the mounting step 311, which can ensure that the lower pot body 32 and the upper pot body 31 are automatically kept concentric, can realize precise positioning, and greatly increase the structural stability and reliability of the entire cooking container 3 when bearing and moving; and a detachable structure 33 is arranged between the mounting step 311 and the lower pot body 32, realizing the complete separation of the cooking container 3. After separation, every surface inside the upper pot body 31 and the lower pot body 32 is completely exposed, and the user can clean every corner without any obstacle, realizing thorough cleaning.

[0051] The top end surface of the lower pot body 32 is in contact with the bottom surface of the mounting step 311 of the upper pot body 31, which forms an annular plane seal on the basis of radial sealing. Under the locking force of the detachable structure 33, the two planes can be tightly fitted, effectively preventing the hot air from leaking from the joint between the upper pot body 31 and the lower pot body 32.

[0052] The detachable structure 33 comprises a plurality of limiting ribs 331 arranged outside the mounting step 311 and a plurality of buckles 332 arranged inside the lower pot body 32. The plurality of limiting ribs 331 are uniformly distributed along the circumference of the mounting step 311 and are arranged upwardly from bottom to top. The plurality of buckles 332 are uniformly distributed along the circumference of the lower pot body 32 and correspond to the plurality of limiting ribs 331 one by one. In other embodiments, the mounting step 311 can be arranged outside the lower pot body 32, and the detachable structure 33 is arranged between the inner wall 111 of the mounting step 311 and the outer wall 112 of the lower pot body 32.

[0053] During installation, the mounting step 311 of the upper pot body 31 is inserted into the lower pot body 32, and the lower pot body 32 is rotated so that the buckle 332 is rotated upwardly above the limiting rib 331. When the top of the lower pot body 32 abuts against the mounting step 311, the buckle 332 is arranged between the limiting rib 331 and the mounting step 311. When an upward force is applied, the buckle 332 will be stuck on the top of the limiting rib 331, and it cannot be separated unless an unlocking force in the opposite direction is applied. This structure provides strong axial locking force, ensuring that the upper pot body 31 and the lower pot body 32 will not separate during pulling or moving. In addition, the rotating buckle 332 structure can make the joint surface of the upper pot body 31 and the lower pot body 32 tightly fit, effectively reducing air leakage, thereby ensuring the thermal efficiency and air pressure of the entire hot air circulation system and ensuring the cooking effect.

[0054] The design of the plurality of limiting ribs 331 and the plurality of buckles 332 makes the locking force uniformly distributed on the entire circumference of the lower pot body 32, which avoids stress concentration and prevents the upper pot body 31 and the lower pot body 32 from deforming, and also ensures the stability of the connection and the uniformity of the sealing.

[0055] When disassembly is required, the lower pot body 32 is rotated in the opposite direction, and the upper pot body 31 is lifted upwardly, so that the upper pot body 31 and the lower pot body 32 are separated. The user only needs to "put in-rotate" to complete the installation, and "reverse rotation-lift" to complete the disassembly. The entire process does not require any tools and does not require multiple rotations like threaded connection. The operation is simple, fast, improves the operation convenience and user experience.

[0056] In other embodiments, the mounting step 311 and the lower pot body 32 can also be connected by magnetic attraction, threaded connection or bolt fixation.

[0057] The installation step 311 of the upper pot body 31 is provided with a food cooking vessel 312 for placing food, and the food cooking vessel 312 is provided with a plurality of through holes. The oil produced by the food during cooking is dropped downward through the through holes on the food cooking vessel 312 into the lower pot body 32, and the hot air entering the lower pot body 32 through the air guide holes 321 flows from bottom to top under the suction of the fan 221, and enters the inside of the upper pot body 31 through the through holes, forcing the hot air to blow upward from multiple dispersed points, thereby avoiding the airflow dead angle that may be formed by a single air inlet, making the distribution of hot air in the cooking container 3 more uniform, and the food is also heated more uniformly; the hot air rises from the bottom, needs to pass through the entire height of the food, has a larger contact area and a longer time with the food, and the heat exchange is more sufficient, which helps to improve the taste and heating effect of the food.

[0058] The air guide cover 5 is arranged in the interlayer cavity 8 and covers the lower pot body 32. The air guide cover 5 and the lower pot body 32 form a hot air channel 9 in communication with the interlayer cavity 8. The first heating element 4 is arranged in the hot air channel 9 and corresponds to the air guide hole 321, so that the hot air flow is sucked into the cooking container 3 by the air circulation assembly 22 to heat the food. The hot air circulation is not affected, and the air guide cover 5 does not affect the overall visual effect. The first heating element 4 is arranged in the air guide cover 5, so that the heat generated by the first heating element 4 is highly concentrated and efficiently utilized. The first heating element 4 corresponds to the air guide hole 321 of the side wall of the lower pot body 32, and the heat is directly used to heat the air flowing through the hot air channel 9. The heat is almost wasted by the air and is used for cooking. The energy waste and component aging caused by the upward loss of part of the heat to the machine head 2 in the traditional top heating are avoided.

[0059] Since the hot air channel 9 and the first heating element 4 are arranged around the lower pot body 32, the heat generated by the first heating element 4 is uniformly distributed around the side wall of the lower pot body 32. The suction of the fan 221 sucks the hot air into the inside of the cooking container 3 through the air guide hole 321 of the lower pot body 32, so that the hot air directly impacts and surrounds the food from all around at multiple angles, so that the food can be quickly and uniformly heated by the hot air, thereby realizing the taste of crisp outside and tender inside, and the heating efficiency is high, so that the preheating speed and the cooking speed are improved.

[0060] During cooking, only the splashed oil stains and food debris exist in the inside of the cooking container 3 and the circulating hot air. Since the first heating element 4 is placed in the hot air channel 9 inside the air guide cover 5 and outside the lower pot body 32, it does not directly contact the oil stains in the cooking container 3. Compared with the heating element of the existing air fryer located above the pot body and directly exposed to the splashed oil stains, the physical isolation of the first heating element 4 from the oil stains is realized, and the cleaning difficulty of the first heating element 4 is greatly reduced.

[0061] In combination Figure 6The top end of the air baffle 5 is provided with an opening for the lower pot body 32 to pass through, and the opening is provided with an inwardly extending mounting edge 51. The mounting step 311 of the upper pot body 31 abuts and supports on the mounting edge 51, so as to place the pot body assembly on the mounting edge 51 of the air baffle 5, facilitate the taking and placing of the pot body assembly, and at the same time, the mounting step 311 can accurately abut on the mounting edge 51 of the top of the air baffle 5 to form an effective seal, prevent hot air from leaking from there, and ensure that all the hot air enters from the air guide holes 321 of the lower pot body 32.

[0062] Moreover, the length of the air baffle 5 extending into the inner container 132 is less than 1 / 3-1 / 2 of the height of the inner container 132. If the air baffle 5 extends too long, even to the bottom, it will seriously block the cavity space in the inner container 132, hinder the smooth flow of the air flow from downward to upward, and form a huge ventilation resistance, so as to ensure that there is a large and unobstructed annular space for the air flow to change direction.

[0063] It should be noted that the outer diameter of the air baffle 5 is greater than the outer diameter of the upper pot body 31, the gap between the upper pot body 31 and the machine body 1 is 27-29 mm, the gap between the air baffle 5 and the machine body 1 is 20-22 mm, and the gap between the inner container 132 and the air baffle 5 is 12-13 mm. These gaps form a flow channel with gradually changing cross-sectional area to ensure the best circulation efficiency.

[0064] The gap between the upper pot body 31 and the machine body 1 forms the inlet or upstream of the interlayer cavity 8, about 28 mm, and the cross-sectional area is relatively large, which can receive a large amount of air flow from the fan 221 at a relatively low flow rate and wind resistance, and provide sufficient air volume basis for the entire circulation system, avoiding huge wind noise and energy loss due to narrow inlet. The gap between the air baffle 5 and the machine body 1 forms an acceleration section of the interlayer cavity 8, about 21 mm. The cross-sectional area here is smaller than that of the upper channel. When the air flow passes through a narrower channel, the flow rate will increase. This section is designed to preliminarily accelerate the air flow, preparing for the subsequent entry into a narrower channel. The gap between the inner container 132 and the air baffle 5 forms a high-speed injection section of the interlayer cavity 8, about 12.5 mm. This is the narrowest part of the flow channel. The air flow is accelerated to the highest speed here, so as to obtain higher momentum and wind pressure, facilitating the air flow to enter the hot air channel 9 under the reflection of the inner container 132.

[0065] This tapered flow channel design can smoothly and efficiently accelerate the air flow. Higher wind speed and wind pressure can make the hot air penetrate deeper into the food, not only improving the heat exchange efficiency and shortening the cooking time, but also ensuring that the hot air can enter uniformly and powerfully from the air guide holes 321 around the lower pot body 32, eliminating hot air dead angles, and achieving uniform heating of the food.

[0066] The top of the air deflector 5 is provided with an inclined surface 52 inclined inward from bottom to top, which can guide the airflow in the interlayer cavity 8, greatly reduce the turbulence and resistance caused by the sudden change of flow channel, make the airflow more concentrated and orderly, thereby improving the working efficiency of the fan 221, reducing energy loss and noise. And the arc chamfer between the inclined surface 52 and the mounting edge 51 makes the inclined surface 52 and the mounting edge 51 smoothly connected, the airflow can smoothly flow along the profile of the top of the air deflector 5, eliminating the flow dead angle and reducing the generation of vortex, further reducing the flow resistance and noise.

[0067] The lower pot body 32 is provided below with an oil receiving tray 6, and the bottom wall of the lower pot body 32 is provided with an oil leakage hole 322 corresponding to the oil receiving tray 6. The oil generated during the cooking of food drops downward through the through hole on the food cooking utensil 312 into the lower pot body 32, and then drops downward through the oil leakage hole 322 into the oil receiving tray 6. If the dropped oil accumulates at the bottom of the lower pot body 32, the hot air entering the lower pot body 32 through the air guide hole 321 will blow the liquid oil again, forming oil mist and re-attaching to the surface of the food. The present scheme allows the oil to immediately leave the lower pot body 32 and fall into the oil receiving tray 6 below through the oil leakage hole 322, so as to ensure that the surface of the food is always heated by dry hot air, thereby fundamentally improving the taste of the cooked food.

[0068] The oil receiving tray 6 has a larger diameter than the outer diameter of the lower pot body 32, and the bottom of the lower pot body 32 extends into the oil receiving tray 6, so that the oil in the lower pot body 32 can smoothly drop into the oil receiving tray 6. Even if the oil drops slightly splashes or deviates, it can be caught by the oil receiving tray 6, avoiding the penetration of oil into the inside of the machine body 1.

[0069] The gap between the outer wall of the oil receiving tray 6 and the air deflector 5 is communicated with the hot air channel 9, which ensures that the airflow in the interlayer cavity 8 enters the hot air channel 9 under the guidance of the inner container 132. The gap between the oil receiving tray 6 and the air deflector 5 is 9-11mm, and the gap between the lower pot body 32 and the air deflector 5 is 13-15mm, which ensures that sufficient air flow can smoothly reach and pass through the air guide hole 321 of the side wall of the lower pot body 32 to heat the food.

[0070] The inner diameter of the first heating element 4 is larger than the outer diameter of the oil receiving tray 6, so that the oil receiving tray 6 can be taken out after cooking, facilitating the replacement and cleaning of the oil receiving tray 6.

[0071] Combining Figure 6 And Figure 7The body 1 is provided with a mounting bracket 7, the mounting bracket 7 is provided with a first plane, the oil receiving disc 6 is abutted and supported on the first plane of the mounting bracket 7, and the first plane provides a special mounting position for the oil receiving disc 6, so that the oil receiving disc 6 has no connection relationship with the cooking container 3 and the air guide cover 5, and the installation and disassembly of the oil receiving disc 6 are facilitated; the diameter of the top opening of the air guide cover 5 can be greater than the outer diameter of the oil receiving disc 6, when cleaning is needed, the cooking container 3 is taken out, the oil receiving disc 6 can be directly and easily lifted vertically upward by hand, and cleaning or oil pouring can be performed, so that the operation difficulty is greatly reduced; because the disassembly is extremely convenient, the oil receiving disc 6 can be cleaned every time after cooking is completed, and accumulation and acidification of oil are avoided, so that the hidden danger of health is fundamentally solved.

[0072] The second plane is provided on the mounting bracket 7 and located outside the first plane, and the air guide cover 5 is abutted and supported on the second plane of the mounting bracket 7, so that the installation and disassembly of the air guide cover 5 are facilitated. It can be understood that the air guide cover 5 is a necessary path for hot air, and the inner wall 111 and the outer wall 112 of the air guide cover 5 will be attached with oil vapor after long-term use. The air guide cover 5 is simply placed through the second plane, and the user can easily take it out of the body 1 to perform thorough washing, so that dirt and odor are prevented, and deep cleaning is truly realized. The second plane is located outside the first plane, and this layout makes the air guide cover 5 and the oil receiving disc 6 two completely independent modules. The user can take out the air guide cover 5 first and then take out the oil receiving disc 6 separately after taking out the cooking container 3, or take out the oil receiving disc 6 first and then take out the air guide cover 5, the operation path is clear, and there is no interference between the two, so that the convenience of cleaning and maintenance is greatly improved.

[0073] It should be noted that the height of the first plane is higher than the height of the second plane, so that the air guide cover 5 and the oil receiving disc 6 are accurately fixed at the predetermined height and horizontal position, and the height of the first plane determines the distance between the oil receiving disc 6 and the bottom of the lower pot body 32, so as to ensure that the oil can accurately drop into the oil receiving disc 6 from the oil leakage hole 322, and avoid splashing or dripping of the oil outside the oil receiving disc 6 due to too large gap, and pollution of the inside of the group; the height of the second plane directly determines the sealing effect of the installation step 311 of the air guide cover 5 and the upper pot body 31 and the depth of the air guide cover 5 extending into the inner container 132.

[0074] The first plane and the second plane not only provide support, but also limit the radial movement of the oil receiving disc 6 and the air guide cover 5, so as to ensure that the interlayer cavity 8 between the air guide cover 5 and the body 1 and the gap between the oil receiving disc 6 and the air guide cover 5 remain uniform, and also ensure that the lower pot body 32 can accurately pass through the opening at the top of the air guide cover 5, and form a uniform annular gap between the air guide cover 5, that is, the hot air channel 9.

[0075] When installing, the oil pan 6 is placed on the first plane of the mounting bracket 7, then the air baffle 5 is placed on the second plane of the mounting bracket 7, and the cooking container 3 is placed on the air baffle 5, and the lower pot body 32 of the cooking container 3 extends into the air baffle 5 through the top opening of the air baffle 5, and the mounting step 311 of the upper pot body 31 abuts against the mounting edge 51 at the top of the air baffle 5, so that the assembly of the cooking device is completed. After cooking, the cooking container 3 is taken out from the opening of the machine body 1, and the air baffle 5 and the oil pan 6 are taken out in turn, and in combination with the detachable structure 33 of the upper pot body 31 and the lower pot body 32, the inside of the machine body 1 and each component can be thoroughly cleaned.

[0076] The layered and overlapped structure makes the cooking container 3, the oil pan 6 and the air baffle 5 can be independently installed and detached, without complex screw fixing or buckle 332 connection between each other, the assembly process is relatively simple, and the user is also relatively convenient to clean. In addition, the cooking container 3 is pressed on the air baffle 5 by its own weight, and the air baffle 5 is pressed on the mounting bracket 7, and the layered and overlapped mode forms reliable sealing in the vertical direction, further improving the air tightness of the circulating air duct.

[0077] The mounting bracket 7 includes a first horizontal edge 71, a first vertical edge 72, a second horizontal edge 73, a second vertical edge 74, a third horizontal edge 75 and a third vertical edge 76 connected in sequence, and the mounting bracket 7 is integrally formed; the height of the second horizontal edge 73 is higher than the height of the first horizontal edge 71, and the height of the first horizontal edge 71 is higher than the height of the third horizontal edge 75, and the first plane is formed by the first horizontal edge 71, and the second plane is formed by the third horizontal edge 75.

[0078] The mounting bracket 7 is provided with a plurality of mounting brackets 7, and the plurality of mounting brackets 7 are distributed along the circumference of the machine body 1 and connected with the machine body 1 through locking members, and the third vertical edge 76 of the mounting bracket 7 is provided with a first locking hole 77, and the inner container 132 is provided with a connecting hole corresponding to the first locking hole 77, and the first locking hole 77 and the corresponding connecting hole are provided with locking members such as bolts, so that the mounting and dismounting of the mounting bracket 7 are facilitated. And the second horizontal edge 73 of the mounting bracket 7 is provided with a second locking hole 78, so as to install a fixing member for fixing the first heating member 4 through a bolt.

[0079] In combination Figure 2The body 1 is provided with a handle 11, the handle 11 is hollowly arranged in an arc shape or a U shape, and includes an inner wall 111 and an outer wall 112. The bottom of the inner wall 111 is provided with a first positioning hole 115. The outer shell 131 is provided with a second positioning hole 131 corresponding to the first positioning hole 115. A locking member such as a bolt is arranged between the first positioning hole 115 and the second positioning hole 131 to fixedly connect the handle 11 and the outer shell 131. In order to improve the overall strength of the handle 11, a support member 116 is arranged between the top and the bottom of the inner wall 111 of the handle 11. In addition, a positioning and matching structure is arranged between the handle 11 and the transparent shell 14. The positioning and matching structure includes a mounting block arranged on the transparent shell 14 and a positioning block 114 arranged on the handle 11. The mounting block is provided with a mounting groove for the positioning block 114 to extend into.

[0080] The handle 11 is provided with a first coupling member 113 protruding upwardly. The head 2 is provided with a second coupling member 24. The second coupling member 24 is provided with a groove 241 for the first coupling member 113 to extend into, thereby providing mechanical positioning for the head 2 to cover. The head 2 can be effectively prevented from being displaced due to vibration or accidental touch, and the stability of the closed state is maintained at all times, thereby maintaining a stable temperature and airflow environment in the cooking container 3 and ensuring the cooking effect of food.

[0081] When the handle 11 needs to be installed, the mounting block is first extended into the handle 11 through the gap, and the handle 11 is moved upwardly so that the positioning block 114 extends into the mounting groove. When the handle 11 cannot be moved upwardly, the first positioning hole 115 corresponds to the second positioning hole 131, and the handle 11 is fixed by the locking member. At this time, the handle 11 is fixed to the outside of the base 13 and the transparent shell 14, and the support member 116 is tightly attached to the transparent shell 14. The top of the first coupling member 113 is higher than the top of the transparent shell 14, so as to provide mechanical positioning for the head 2 to cover.

[0082] Embodiment 2: The difference between this embodiment and the above-mentioned embodiments is that the combination of the handle 11 and the transparent shell 14 is realized by the positioning and matching structure.

[0083] The upper pot body 31 and the lower pot body 32 are formed into a whole through the detachable structure 33, and the precise positioning is naturally realized through the cooperation of the flange 323 and the mounting edge 51, which facilitates the putting in or taking out of the pot body assembly 3 from the top opening of the machine body 1 and ensures that the hot air passage 9 is formed between the side wall of the lower pot body 32 and the air guide cover 14, thereby ensuring the effectiveness of the hot air circulation system.

[0084] The pot body assembly 3 can be easily disassembled into the upper pot body 31 and the lower pot body 32 through the detachable structure 33, the mounting step 311 extends into the part of the lower pot body 32, and the upper surface of the flange 323 of the lower pot body 32 can accumulate oil stains after long-term use. Through the simple split design, these hidden areas are completely exposed and can be directly washed with water to achieve thorough cleaning without dead angles.

[0085] In the embodiment, the positioning step is arranged on the lower pot body 32 and above the air guide hole 321, and the first heating element 4 is arranged below the positioning step, which can heat the air flow passing through the hot air passage 9 and shield the first heating element 4, preventing the oil stains inside the cooking container from falling back to the first heating element 4, thereby further protecting the cleanliness of the first heating element 4 and reducing the cleaning demand of the first heating element 4.

[0086] In other embodiments, the air guide holes 321 are arranged on the side wall of the lower pot body 32 and the positioning step, which can make the hot air uniformly diffuse upward, thereby further improving the heating effect of the food.

[0087] Embodiment 3: The difference between the embodiment and the above-mentioned embodiments is that the transparent shell 14 is arranged on the bottom cover 13, and the bottom cover 13 is arranged on the bottom plate 12. Figure 9 When assembling, the bottom cover 13 only needs to be roughly aligned and placed in the transparent shell 14, and the initial positioning can be automatically completed under the action of gravity until the top of the bottom cover 13 abuts against the connecting part 141, the assembly process is one-step, no repeated adjustment is needed, the installation and disassembly of the transparent shell 14 and the bottom cover 13 are facilitated, thereby facilitating the cleaning of each part.

[0088] In other embodiments, the connecting part 141 is arranged on the transparent shell 14 and extends inward, and the mounting groove for the bottom cover 13 to extend into is arranged on the connecting part 141, which can preliminarily position the transparent shell 14.

[0091] The upper pot 31 is a simple cylindrical structure which does not require complex structures. It only needs to be connected to the inner side of the mounting step 311 through the detachable structure 33, or simply arranged on the mounting step 311. This reduces the machining precision of the upper pot 31, and the mounting of the upper pot 31 and the lower pot 32 is simpler.

[0092] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
