Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen equipment, in particular to a split type easy-to-clean cooking equipment. BACKGROUND

[0002] Most of the existing frying and baking equipment is provided with a hot air circulation assembly on the top of the 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] The patent with publication number CN109820432A discloses an air fryer with sufficient heat circulation. A heat circulation air duct is formed between the inner wall of the heat circulation shell and the outer wall of the pot body. A hot air outlet is provided on the upper part of the pot body, and a hot air fan is provided at the hot air outlet. A heating assembly is provided in the interior of the pot body and / or in the heat circulation air duct. The lower part of the pot body is provided with a plurality of hot air inlets. A food basket is provided in the pot body, which divides the interior of the pot body into an upper cavity and a lower cavity. The upper cavity is in communication with the heat circulation air duct through the hot air outlet, and the lower cavity is in communication with the heat circulation air duct through the hot air inlets.

[0004] In the above-mentioned scheme, the heating assembly is located at the top. The hot air needs to enter the heat circulation air duct from the upper hot air fan, reach the lower part of the pot body, and finally enter the pot body to act on the food. The hot air flow path is relatively long. During the long transmission process, the hot air exchanges heat with the air duct, the outer wall of the pot body, and other components, resulting in a large amount of heat energy loss and low heat energy utilization rate. The heating assembly is provided at the top of the pot body, while the hot air flow naturally flows upward. A hot air fan is needed to provide sufficient power to forcibly blow the hot air to the lower part of the pot body, which is not energy efficient. In addition, the positions of the top air guide cover, the heating assembly, and the hot air fan are compact and fixedly installed. The oil stains splashed during cooking are easy to accumulate at this position. Due to the complex structure, it is difficult to clean the air guide cover, the hot air fan, and the heating assembly.

[0012] Optionally, the lower pot is provided with an oil receiving disc below, and the bottom wall of the lower pot is provided with an oil leakage hole corresponding to the oil receiving disc.

[0013] Optionally, the body is provided with a mounting bracket, the mounting bracket is provided with a first plane, and the oil receiving disc abuts and supports on the first plane of the mounting bracket.

[0014] Optionally, the mounting bracket is provided with a second plane outside the first plane, and the air deflector abuts and is supported on the second plane of the mounting bracket.

[0015] Optionally, the mounting bracket is provided with a plurality of mounting brackets, and the plurality of mounting brackets are distributed in the circumferential direction of the machine body and connected to the machine body through the locking member.

[0016] Optionally, the machine body comprises a base and a glass cover above the base, and the upper pot body corresponds to the glass cover and is made of glass.

[0017] In summary, the present application has at least the following beneficial effects: 1. The first heating member heats, and the hot air enters the pot assembly through the ventilation hole under the suction of the fan to heat the food, and the air circulation assembly draws the hot air in the pot assembly to the fan, flows into the air inlet channel under the guidance of the upper reflecting cover, and enters the pot assembly through the hot air channel and the ventilation hole, realizing the circulation of hot air. The first heating member is arranged in the air deflector, so that the heat generated by the first heating member is highly concentrated and efficiently utilized, 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; and the first heating member corresponds to the ventilation hole of the lower pot body, and the heat is directly used to heat the air flowing through the hot air channel, avoiding the loss of long path transportation, and the heat is almost wasted by the air, and is used for cooking, so that the overall cooking speed can be improved. Since the hot air channel and the first heating member are arranged around the lower pot body, the heat generated by the first heating member is evenly distributed around the lower pot body, and the suction of the fan draws the hot air into the pot assembly through the ventilation hole of the lower pot body, so that the hot air directly impacts and surrounds the food from all directions, so that the food can be quickly and uniformly heated, thereby realizing the crispy outside and tender inside, and the heat efficiency is high, so that the preheating speed and the cooking speed are improved. The first heating member is arranged at the lower part, which conforms to the physical law of natural upward of hot air, and the work of the air circulation assembly no longer resists the natural law, but conforms to and assists this law, so that the hot air is better circulated by the air circulation assembly without providing a large power, so that the whole operation is more efficient and the energy consumption is lower. During the cooking process, the splashed oil stains and food debris only exist in the pot assembly and the circulating hot air, and since the first heating member is placed in the hot air channel inside the air deflector and outside the lower pot body, it does not directly contact the oil stains in the pot assembly. 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 member and the oil stains is realized, and the cleaning difficulty of the first heating member is greatly reduced. After cooking, the pot assembly is taken out from the opening at the top of the machine body, avoiding the inconvenience of operating in the narrow space inside the machine body, and the inside of the machine body and the first heating element can be easily cleaned; after separating the upper pot body from the lower pot body, the oil stains in the corners can be completely exposed, and the upper pot body and the lower pot body can be thoroughly cleaned.

[0018] 2、The wind circulation assembly includes a fan and a second heating element located below the fan. The second heating element heats and radiates heat to the upper surface of the food, and also heats the air flow sucked by the fan, ensuring that the hot air entering the next cycle maintains a stable and high enough temperature, avoiding the extension of the cooking time and uneven heating due to the continuous attenuation of heat, and significantly improving the heating efficiency and effect. Under the synergistic action of the first heating element and the second heating element, the food is in an environment surrounded by heat sources from top to bottom and all around. The first heating element is responsible for heating the side and bottom of the food, and the second heating element is responsible for heating the top of the food, which makes the heating of the food more uniform in the entire space, effectively eliminating the cold area caused by insufficient top heating, and improving the heating uniformity of the food.

[0019] 3、The diameter of the fan is greater than or equal to the inner diameter of the upper pot body, so that the fan can suck the air flow inside the pot assembly to the cross-flow fan, and the air flow blown from the side enters the air inlet channel under the guidance of the upper reflector, reducing the air flow blown by the fan into the pot assembly, and ensuring the hot air circulation effect. A large-size fan can provide a large amount of air at a relatively low speed, which can ensure the heat exchange efficiency and will not excessively dry the local surface of the food. This softer air flow can effectively reduce the phenomenon of blowing, atomizing and re-attaching oil droplets on the bottom to the food and the inner wall of the pot assembly, thereby reducing the cleaning burden from the source.

[0020] 4、The upper pot body is provided with an installation step extending inward, and the lower pot body cover is arranged outside the installation step, which can ensure that the lower pot body and the upper pot body are automatically kept concentric, can realize precise positioning, and greatly increase the structural stability and reliability of the entire pot assembly during bearing and moving; and a detachable structure is arranged between the installation step and the lower pot body, realizing complete separation of the pot assembly. After separation, every surface inside the upper pot body and the lower pot body is completely exposed, and the user can clean every corner without any obstacles, realizing thorough cleaning. The top end surface of the lower pot body is in contact with the bottom surface of the upper pot body installation step, which forms an annular plane seal on the basis of radial sealing, so that the two planes can be tightly fitted, effectively preventing the hot air from leaking from the joint between the upper pot body and the lower pot body.

[0021] 5、The top end of the air deflector is provided with an inwardly extending mounting edge, and the mounting step of the upper pot body abuts and supports on the mounting edge to place the pot body assembly on the mounting edge of the air deflector, facilitating the taking and placing of the pot body assembly, while the mounting step can accurately abut the mounting edge of the top of the air deflector to form an effective seal, preventing hot air from leaking from there, and ensuring that all the hot air enters from the ventilation hole of the lower pot body.

[0022] 6、The lower pot body is provided below with an oil receiving tray, and the bottom wall of the lower pot body is provided with an oil leakage hole corresponding to the oil receiving tray. The oil produced during the cooking of food drops downward through the through hole on the food cooking vessel into the lower pot body, and then drops downward through the oil leakage hole into the oil receiving tray. If the dropped oil accumulates at the bottom of the lower pot body, the hot air entering the lower pot body through the ventilation hole will blow the liquid oil again to form oil mist, which re-attaches to the surface of the food. This scheme allows the oil to immediately leave the lower pot body through the oil leakage hole and fall into the oil receiving tray below, which can ensure that the surface of the food is always heated by dry hot air, fundamentally improving the taste of the cooked food.

[0023] 7、The mounting bracket is provided with a first plane, and the oil receiving tray abuts and supports on the first plane of the mounting bracket. The first plane provides a special mounting position for the oil receiving tray, so that the oil receiving tray has no connection relationship with the pot body assembly and the air deflector, facilitating the installation and removal of the oil receiving tray. When cleaning is needed, the pot body assembly is taken out, and the oil receiving tray can be directly and easily lifted vertically upward by hand to clean or pour oil, greatly reducing the operation difficulty. Since the disassembly is extremely convenient, the oil receiving tray can be cleaned every time after cooking is completed, avoiding oil accumulation and acidification, and fundamentally solving the health hazard.

[0024] 8、The air deflector abuts and supports on the second plane of the mounting bracket, facilitating the installation and removal of the air deflector. It can be understood that the air deflector is the only way for hot air, and the inner and outer walls of the air deflector will be attached with oil vapor after long-term use. By simply placing the air deflector on the second plane, the user can easily take it out of the machine body for thorough washing, eliminating dirt accumulation and odor generation, and truly achieving deep cleaning. The second plane is located outside the first plane. This layout makes the air deflector and the oil receiving tray two completely independent modules. The user can first take out the air deflector and then the oil receiving tray after taking out the pot body assembly, or first take out the oil receiving tray and then the air deflector. The operation path is clear, and there is no interference between the two, greatly improving the convenience of cleaning and maintenance. The first plane and the second plane not only provide support but also limit the radial movement of the oil receiving tray and the air deflector, ensuring that the air inlet channel between the air deflector and the machine body and the gap between the oil receiving tray and the air deflector remain uniform, and also ensuring that the lower pot body can accurately pass through the opening at the top of the air deflector to form a uniform annular gap between the air deflector and the machine body.

[0025] 9、The body includes a base with an upward opening and a glass cover connected with the base, and the upper pot body is made of glass material and corresponds to the glass cover, and the all-around visual effect is realized under the cooperation of the glass cover and the upper pot body, the user can easily observe the coloring condition and the cooking progress of the food without frequently opening the machine head, which can help the user accurately grasp the fire, avoid burning or not being cooked through, greatly improve the cooking success rate and user experience.

[0037] The present application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments are only specific illustrations of the present application, and the 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 limiting the present application.

[0038] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the purpose of facilitating the description of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0039] Embodiment 1: The embodiments of the present application disclose a split type easy-to-clean cooking equipment, such as Figure 1 and Figure 2As shown, including the body 1, cover on the body 1 head 2 and located in the body 1 pot assembly 3, head 2 is provided with an opening downward upper reflector 21 and located in the upper reflector 21 wind circulation assembly 22, wind circulation assembly 22 includes fan 221 with motor, the body 1 and pot assembly 3 between the air inlet channel 8 is communicated with wind circulation assembly 22, pot assembly 3 includes upper pot 31 and with upper pot 31 detachable lower pot 32, the side wall of lower pot 32 is provided with ventilation hole 321, lower pot 32 periphery and corresponding ventilation hole 321 position is equipped with the first heating element 4;The body 1 is provided with the air deflector 5 cover in the lower pot 32 outside, the first heating element 4 is located in the air deflector 5, and the lower pot 32 and air deflector 5 have gap and form hot air channel 9 with air inlet channel 8.

[0040] The first heating element 4 heating, hot air flow under the suction of fan 221 through ventilation hole 321 into the pot assembly 3, heat food, and fan 221 will be hot air flow in the pot assembly 3 to fan 221, under the guidance of the upper reflector 21 flow into the air inlet channel 8, and through the hot air channel 9 and ventilation hole 321 into the pot assembly 3, realize the circulation of hot air.

[0041] The first heating element 4 is arranged in the air deflector 5, the heat generated by the first heating element 4 is highly concentrated and efficiently utilized, and the first heating element 4 corresponds to the ventilation hole 321 of the side wall of the lower pot 32, the heat is directly used for heating the air flowing through the hot air channel 9, the heat is almost wasted by the air, and all is used for cooking, avoiding the energy waste and component aging caused by the upward loss of part of the heat to the inside of the head 2 in the traditional top heating.

[0042] Because the hot air channel 9 and the first heating element 4 are arranged around the lower pot 32, the heat generated by the first heating element 4 is evenly distributed around the side wall of the lower pot 32, and the suction of the fan 221 sucks the hot air through the ventilation hole 321 of the lower pot 32 into the inside of the pot assembly 3, so that the hot air directly impacts and surrounds the food from all around and at multiple angles, so that the food can be quickly and evenly heated by the hot air, thereby realizing the crisp outside and tender inside taste, and the heat efficiency is high, so that the preheating speed and the cooking speed are improved.

[0043] In the cooking process, the splashing oil stains and food debris only exist in the inside of the pot assembly 3 and the circulating hot air, because the first heating element 4 is placed in the hot air channel 9 inside the air deflector 5 and outside the lower pot 32, not directly contacting the oil stains in the pot assembly 3, compared with the heating element of the existing air fryer located above the pot, directly exposed to the splashing oil stains, the physical isolation of the first heating element 4 and the oil stains is realized, and the cleaning difficulty of the first heating element 4 is greatly reduced.

[0044] After cooking, the pot assembly 3 is taken out from the opening on 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; after separating the upper pot 31 from the lower pot 32, the oil stains in the corners can be completely exposed, and the upper pot 31 and the lower pot 32 can be thoroughly cleaned.

[0045] In the embodiment, the upper pot 31 is in a cylindrical shape, and the bottom of the upper pot 31 is provided with an opening to communicate the upper pot 31 with the lower pot 32. In other embodiments, the bottom of the upper pot 31 is provided with a bottom wall, and a plurality of air inlet holes are arranged on the bottom wall of the upper pot 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.

[0046] It should be noted that the fan 221 is arranged as a cross-flow fan 221, and the diameter of the cross-flow fan 221 is greater than or equal to the inner diameter of the upper pot 31, so that the cross-flow fan 221 can draw the airflow inside the pot assembly 3 to the cross-flow fan 221, and the airflow blown from the peripheral side can enter the air inlet channel 8 under the guidance of the upper reflector 21, reducing the airflow blown by the fan 221 into the pot assembly 3, and ensuring the heat circulation effect. The large-size cross-flow fan 221 can provide a large air volume at a relatively low speed, which can not only ensure the heat exchange efficiency, but also will not excessively dry the local surface of the food, and the more gentle airflow can effectively reduce the phenomenon that the bottom oil droplets are blown up, atomized and secondarily attached to the food and the inner wall 111 of the pot assembly 3, thereby reducing the cleaning burden from the source.

[0047] Further, in combination with Figure 4 , the head 2 is provided with a baffle 23 below the fan 221, and the baffle 23 is provided with a return air opening corresponding to the fan 221, and the baffle 23 separates the fan 221 from the space inside the pot assembly 3, so that when the fan 221 works, all the suction force generated by the fan 221 can be concentrated on the inside of the pot assembly 3, rather than being dispersed to the whole cavity of the head 2, which makes the hot airflow in the pot assembly 3 be efficiently and concentratedly sucked up through the return air opening, and the baffle 23 can also prevent the airflow blown from the peripheral side of the fan 221 from being blown directly downward into the pot assembly 3, further improving the circulation efficiency of the airflow.

[0048] The body 1 is provided with a handle 11, and the handle 11 is provided with a first coupling member 113 protruding upward, and the head 2 is provided with a second coupling member 24, and the second coupling member 24 is provided with a groove 241 for the first coupling member 113 to extend into, which provides mechanical positioning for the head 2 to be closed, effectively preventing the head 2 from being displaced due to vibration or accidental touch, and maintaining the stability of the closed state, thereby maintaining the stable temperature and airflow environment in the pot assembly 3, and ensuring the cooking effect of the food.

[0049] In combination with Figure 3The bottom of the upper pot body 31 is provided with an inwardly extending mounting step 311 which is integrally formed with the upper pot body 31, and the lower pot body 32 is covered outside the mounting step 311, that is, the inner diameter of the upper pot body 31 is larger than that of the lower pot body 32, which can ensure that the lower pot body 32 and the upper pot body 31 are automatically kept concentric, precise positioning can be achieved, and the structural stability and reliability of the entire pot body assembly 3 during bearing and movement are greatly increased; and a detachable structure 33 is arranged between the mounting step 311 and the lower pot body 32, which realizes complete separation of the pot body assembly 3, and after separation, each surface inside the upper pot body 31 and the lower pot body 32 is completely exposed, so that the user can clean every corner without any obstacles, and thorough cleaning is achieved.

[0050] 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, and under the action of the locking force of the detachable structure 33, the two planes can be tightly attached, effectively preventing hot air from leaking from the joint between the upper pot body 31 and the lower pot body 32.

[0051] The detachable structure 33 includes 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 the limiting ribs 331 are arranged upwardly from bottom to top, and the plurality of buckles 332 are uniformly distributed along the circumference of the lower pot body 32 and correspond one-to-one to the plurality of limiting ribs 331. In other embodiments, the mounting step 311 can also be covered outside the lower pot body 32, and the detachable structure 33 thereof is arranged between the inner wall 111 of the mounting step 311 and the outer wall 112 of the lower pot body 32.

[0052] 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, and when there is an upward force, the buckle 332 will be stuck on the top of the limiting rib 331, and unless an unlocking force in the opposite direction is applied, it cannot be separated; this structure provides strong axial locking force, which ensures that the upper pot body 31 and the lower pot body 32 will not separate during pulling or moving. Moreover, the rotating buckle 332 structure can make the joint surface of the upper pot body 31 and the lower pot body 32 tightly attached, effectively reducing air leakage, thereby ensuring the thermal efficiency and air pressure of the entire hot air circulation system and ensuring the cooking effect.

[0053] 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 deformation of the upper pot body 31 and the lower pot body 32, and also ensures the stability of the connection and the uniformity of the seal.

[0054] When disassembly is needed, the lower pot body 32 is rotated in the opposite direction, and the upper pot body 31 is lifted upwards, 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, nor does it require multiple rotations like threaded connection. The operation is simple, fast, improves the convenience of operation and user experience.

[0055] In other embodiments, the installation step 311 and the lower pot body 32 can also be connected by magnetic attraction, threaded connection or bolt fixation.

[0056] The installation step 311 of the upper pot body 31 is provided with a food cooking vessel 312 for placing food. The food cooking vessel 312 is provided with a plurality of through holes. The oil produced by the food during cooking falls downward through the through holes on the food cooking vessel 312 into the lower pot body 32. The hot air in the lower pot body 32 enters the lower pot body 32 through the ventilation holes 321 under the suction action of the fan 221, flows from bottom to top, 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. This avoids the airflow dead angle that may be formed by a single air inlet, so that the distribution of hot air in the pot body assembly 3 is more uniform, and the food is 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 with the food, a longer time, and a more sufficient heat exchange, which helps to improve the taste and heating effect of the food.

[0057] The top end of the air guide cover 5 is provided with an opening for the lower pot body 32 to pass through. The opening is provided with an installation edge 51 extending inward. The installation step 311 of the upper pot body 31 abuts and supports on the installation edge 51, so as to place the pot body assembly 3 on the installation edge 51 of the air guide cover 5. At the same time, the installation step 311 can accurately abut the installation edge 51 at the top of the air guide cover 5, forming an effective seal to prevent hot air from leaking from there, and ensuring that all hot air enters from the ventilation holes 321 of the lower pot body 32.

[0058] The machine body 1 is also provided with a lower reflection cover 12 opening upward. The lower reflection cover 12 is arranged in a U shape or an arc shape. The lower reflection cover 12 is connected with the machine body 1, and the bottom end of the air guide cover 5 extends into the lower reflection cover 12. The internal space of the lower reflection cover 12 communicates the air inlet channel 8 and the hot air channel 9, so that the airflow in the air inlet channel 8 flows downward into the lower reflection cover 12. The curved surface structure of the lower reflection cover 12 provides a continuous guide surface for the downward flowing airflow, which can change the direction of the airflow from downward to upward, so that the airflow flows upward into the hot air channel 9, and greatly reduces the energy loss caused by the sudden change of direction.

[0059] The length of the wind deflector 5 extending into the lower reflector 12 is less than 1 / 3-1 / 2 of the height of the lower reflector 12. If the wind deflector 5 extends too long, even to the bottom, it will seriously block the cavity space in the lower reflector 12, hinder the smooth flow of the air from downward to upward, and form a huge ventilation resistance, ensuring that there is a large and unobstructed annular space for the air flow to change direction.

[0060] It should be noted that the outer diameter of the wind deflector 5 is larger than the outer diameter of the upper pot body 31, the gap between the upper pot body 31 and the machine body 1 is 27-29mm, the gap between the wind deflector 5 and the machine body 1 is 20-22mm, and the gap between the lower reflector 12 and the wind deflector 5 is 12-13mm. These gaps form a flow channel with gradually changing cross-sectional area to ensure the best circulation efficiency.

[0061] The gap between the upper pot body 31 and the machine body 1 forms the inlet or upstream of the air inlet channel 8, about 28mm, with a relatively large cross-sectional area, which can receive a large amount of airflow from the fan 221 at a relatively low flow rate and wind resistance, providing sufficient air volume basis for the entire circulation system, avoiding huge wind noise and energy loss due to narrow inlet. The gap between the wind deflector 5 and the machine body 1 forms the acceleration section of the air inlet channel 8, about 21mm, the cross-sectional area here is smaller than the upper channel, when the airflow passes through a narrower channel, the flow rate will increase, this section is designed to preliminarily accelerate the airflow, preparing for the subsequent entry into a narrower channel. The gap between the lower reflector 12 and the wind deflector 5 forms the high-speed injection section of the air inlet channel 8, about 12.5mm, which is the narrowest part of the flow channel, the airflow is accelerated to the highest speed here, thereby obtaining higher momentum and wind pressure, facilitating the airflow to enter the hot air channel 9 under the reflection of the lower reflector 12.

[0062] This tapered flow channel design can smoothly and efficiently accelerate the airflow, and higher wind speed and wind pressure can allow the hot air to penetrate deeper into the food, not only improving heat exchange efficiency and shortening cooking time, but also ensuring that the hot air can enter evenly and powerfully from the ventilation holes 321 around the lower pot body 32, eliminating hot air dead angles and achieving uniform heating of the food.

[0063] The top of the wind deflector 5 is provided with an inclined surface 52 inclined inward from bottom to top, which can guide the airflow in the air inlet channel 8, greatly reducing the turbulence and resistance caused by sudden changes in the flow channel, making 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 smoothly connects the inclined surface 52 and the mounting edge 51, the airflow can smoothly flow along the contour of the top of the wind deflector 5, eliminating flow dead angles and reducing vortex generation, further reducing flow resistance and noise.

[0064] The lower oil pan 6 is arranged below the lower pot body 32, and the bottom wall of the lower pot body 32 is provided with an oil leakage hole 322 corresponding to the oil pan 6. The oil generated during the cooking of food drops downward through the through holes in the food cooking utensil 312 into the lower pot body 32, and then drops downward through the oil leakage hole 322 into the oil pan 6 below. If the oil drops accumulate at the bottom of the lower pot body 32, the hot air entering the lower pot body 32 through the ventilation hole 321 will blow the liquid oil again to form oil mist and reattach to the surface of the food. The present scheme can ensure that the surface of the food is always heated by dry hot air by making the oil immediately leave the lower pot body 32 and fall into the oil pan 6 below, thereby fundamentally improving the taste of the cooked food.

[0065] The oil pan 6 has an outer diameter greater than that of the lower pot body 32, and the bottom of the lower pot body 32 extends into the oil pan 6, so that the oil in the lower pot body 32 can smoothly drop into the oil pan 6. Even if the oil drops slightly splash or deviate, it can be caught by the oil pan 6 to avoid the oil penetrating out of the oil pan 6 to pollute the inside of the machine body 1.

[0066] The gap between the outer wall of the oil pan 6 and the air guide cover 5 is communicated with the hot air channel 9, which ensures that the airflow in the air inlet channel 8 enters the hot air channel 9 under the guidance of the lower reflector 12. The gap between the oil pan 6 and the air guide cover 5 is 9-11 mm, and the gap between the lower pot body 32 and the air guide cover 5 is 13-15 mm, which ensures that sufficient air can smoothly reach and pass through the ventilation hole 321 of the side wall of the lower pot body 32 to heat the food.

[0067] The inner diameter of the first heating element 4 is greater than the outer diameter of the oil pan 6, so that the oil pan 6 can be removed after cooking, facilitating the replacement and cleaning of the oil pan 6.

[0068] In combination with Figure 4 and Figure 5 , the machine body 1 is provided with a mounting bracket 7, and the mounting bracket 7 is provided with a first plane. The oil pan 6 abuts and supports on the first plane of the mounting bracket 7, and the first plane provides a special mounting position for the oil pan 6, so that the oil pan 6 has no connection relationship with the pot assembly 3 and the air guide cover 5, facilitating the installation and disassembly of the oil pan 6. The top opening diameter of the air guide cover 5 can be greater than the outer diameter of the oil pan 6. When cleaning is needed, the pot assembly 3 is removed, and the oil pan 6 can be directly and easily lifted vertically upward by hand, so that cleaning or oil pouring can be performed, greatly reducing the operation difficulty. Since the disassembly is extremely convenient, the oil pan 6 can be cleaned every time after cooking is completed, avoiding oil accumulation and acidification, and fundamentally solving the health hazard.

[0069] The second plane is located outside the first plane, and the air deflector 5 abuts and is supported on the second plane of the mounting bracket 7, facilitating installation and disassembly of the air deflector 5. It can be understood that the air deflector 5 is the only way for hot air to pass through, and the inner wall and outer wall of the air deflector 5 will be attached with oil and gas after long-term use. By simply placing the air deflector 5 on the second plane, the user can easily remove it from the body 1 for thorough cleaning, eliminating dirt accumulation and odor generation, and truly achieving deep cleaning.

[0070] The second plane is located outside the first plane, and the air deflector 5 abuts and is supported on the second plane of the mounting bracket 7, facilitating installation and disassembly of the air deflector 5. It can be understood that the air deflector 5 is the only way for hot air to pass through, and the inner wall and outer wall of the air deflector 5 will be attached with oil and gas after long-term use. By simply placing the air deflector 5 on the second plane, the user can easily remove it from the body 1 for thorough cleaning, eliminating dirt accumulation and odor generation, and truly achieving deep cleaning.

[0071] It should be noted that the height of the first plane is higher than the height of the second plane, so that the air deflector 5 and the oil pan 6 are accurately fixed at the predetermined height and horizontal position. The height of the first plane determines the distance between the oil pan 6 and the bottom of the lower pot body 32 to ensure that the oil can accurately drop into the oil pan 6 from the oil leakage hole 322, avoiding splashing or dripping of oil outside the oil pan 6 due to excessive gap, which pollutes the inside of the group. The height of the second plane directly determines the sealing effect of the installation step 311 of the upper pot body 31 and the installation edge 51 of the air deflector 5 and the depth of the air deflector 5 extending into the lower reflector 12.

[0072] The first plane and the second plane not only provide support, but also limit the radial movement of the oil pan 6 and the air deflector 5, ensuring that the air inlet channel 8 between the air deflector 5 and the body 1 and the gap between the oil pan 6 and the air deflector 5 remain uniform, and that the lower pot body 32 can accurately pass through the opening at the top of the air deflector 5 to form a uniform annular gap between the air deflector 5, i.e. the hot air channel 9.

[0073] During installation, the oil pan 6 is placed on the first plane of the mounting bracket 7, the air deflector 5 is placed on the second plane of the mounting bracket 7, and the pot body assembly 3 is placed on the air deflector 5, with the lower pot body 32 extending into the air deflector 5 through the top opening of the air deflector 5, and the installation step 311 of the upper pot body 31 abutting the installation edge 51 at the top of the air deflector 5, thereby completing the assembly of the cooking equipment. After cooking, the pot body assembly 3 is removed from the opening of the body 1, and the air deflector 5 and the oil pan 6 are removed in turn. Combined with the detachable structure 33 of the upper pot body 31 and the lower pot body 32, the inside of the body 1 and each component can be thoroughly cleaned.

[0074] The layered and overlapped structure enables the pot body assembly 3, the oil receiving disc 6 and the air guide cover 5 to be independently installed and removed without complex screw fixing or buckle 332 connection, and the assembly process is relatively simple and the user cleaning is relatively convenient. In addition, the pot body assembly 3 is pressed on the air guide cover 5 by its own weight, and the air guide cover 5 is pressed on the mounting bracket 7. The layer-by-layer pressing manner forms reliable sealing in the vertical direction, further improving the air tightness of the circulating air duct.

[0075] The mounting bracket 7 comprises a first horizontal side 71, a first vertical side 72, a second horizontal side 73, a second vertical side 74, a third horizontal side 75 and a third vertical side 76 connected in sequence, and the mounting bracket 7 is integrally formed; the height of the second horizontal side 73 is higher than the height of the first horizontal side 71, and the height of the first horizontal side 71 is higher than the height of the third horizontal side 75, the first horizontal side 71 forms a first plane, and the third horizontal side 75 forms a second plane.

[0076] 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. The third vertical side 76 of the mounting bracket 7 is provided with a first locking hole 77, and the lower reflector 12 is provided with a connecting hole corresponding to the first locking hole 77. The first locking hole 77 and the corresponding connecting hole are provided with locking members such as bolts, which facilitates the installation and removal of the mounting bracket 7. The second horizontal side 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.

[0078] The upper pot body 31 and the lower pot body 32 form a whole through the detachable structure 33, and the precise positioning is naturally realized through the cooperation of the flange 323 and the installation edge 51. The pot body assembly 3 is convenient to put into or take out from the opening at the top of the machine body 1, and the effective of the hot air circulating system is ensured.

[0079] And through the detachable structure 33, the pot body assembly 3 can be easily disassembled into two independent parts of the upper pot body 31 and the lower pot body 32, the part of the installation step 311 extending into the lower pot body 32, and the upper surface of the flange 323 of the lower pot body 32, which 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.

[0080] Embodiment 3: The difference between this embodiment and the above embodiments is that Figure 7 , the top of the air guide cover 5 is provided with an opening for the lower pot body 32 to pass through, and the opening is provided with an installation edge 51 extending outward, and the top of the lower pot body 32 is provided with an installation step 311 extending outward, and the installation step 311 abuts and supports on the installation edge 51, and the upper pot body 31 is in a cylindrical structure, and the outer side of the upper pot body 31 and the inner side of the installation step 311 are provided with a detachable structure 33.

[0084] Under the synergistic effect of the first heating element 4 and the second heating element 222, the food is in an environment surrounded by heat sources from top to bottom and all around, and the first heating element 4 is responsible for heating the side and bottom of the food, and the second heating element 222 is responsible for heating the top of the food, which makes the food heated more evenly in the entire space, effectively eliminating the cold area caused by insufficient top heating, and improving the heating uniformity of the food.

[0085] Embodiment 4: The difference between the embodiment and the above-mentioned embodiments is that Figure 9 The body 1 comprises a base 13 opening upward and a glass cover 14 connected with the base 13, and the upper pot body 31 is made of glass and corresponds to the glass cover 14. The all-around visual effect is realized through the cooperation of the glass cover 14 and the upper pot body 31. The user can easily observe the coloring condition and the cooking progress of the food without frequently opening the machine head 2, which can help the user accurately grasp the fire and avoid burning or undercooking, greatly improving the cooking success rate and user experience.

The connecting part 141 is arc-shaped at the connecting part with the glass cover 14, which can guide the hot air in the air inlet channel 8 into the lower reflecting cover 12, reduce the vortex and energy loss at this position, improve the uniformity of the air flow speed, and ensure the stability of the hot air circulation.

[0087] The rim of the lower reflecting cover 12 is arranged above the connecting part 141, and the lower reflecting cover 12 is connected with the base 13 through a locking member to firmly fix the glass cover 14 and the base 13. In the embodiment, at least one connecting block 15 is arranged in the base 13. The base 13 and the connecting block 15 are provided with a through hole 151. A fixing rod 16 is arranged in the through hole 151. The fixing rod 16 is provided with a threaded hole.
