Abstract
Description
Technical Field
[0001] This utility model belongs to the field of household appliance technology, and in particular relates to a rotary heating air fryer. Background Technology
[0002] There are generally two types of air fryers. One type has a heating element at the top of the pot, heating food from above. An opening on one side allows users to slide a baking tray into or remove it from the pot. The other type is a flip-top design, consisting of a pot and a lid. The lid flips open to reveal the heating element, which heats food from the top. The baking tray is then removed or placed into the pot through an opening at the top. Both types of air fryers require the food to be placed on the baking tray before turning on the air fryer. The top heating structure heats the air, and then the fan blades blow the hot air toward the food, causing the moisture on the surface of the food to evaporate quickly, thus achieving the effect of frying. However, this method of frying food will result in uneven heating. Because the position of the food is fixed after it is placed on the baking tray, and the heating structure is located on top of the pot or lid, when hot air blows onto the food from above, it will cause each side of the food to be heated to a different degree. Furthermore, when multiple foods are placed or piled up in contact, the areas where the foods are in contact are even less likely to be heated by the airflow. Summary of the Invention
[0003] The purpose of this utility model is to provide an air fryer that can rotate and heat food during cooking, in order to solve the problems existing in the prior art. To achieve the above purpose, the specific technical solution of this utility model is as follows: a rotating heating air fryer, including a pot body and a pot lid set on the pot body. The pot body is provided with a pot inner liner, and the pot inner liner is provided with a cooking chamber. The cooking chamber is provided with a rotating mechanism that can rotate the food. The pot inner liner is provided with a uniform heating mechanism that heats the air and makes the air flow. The uniform heating mechanism is provided with an exhaust mechanism. By driving the rotating mechanism, the food can be rotated in the cooking chamber. With the use of the uniform heating mechanism, the food can be heated by hot air while rotating, so as to achieve uniform heating of the food.
[0004] Preferably, the hot air blown by the uniform heating mechanism is blown into the cooking cavity from a position higher than the food, and the hot air is blown towards the food at an inclined angle. When the rotating mechanism drives the food to rotate in the cooking cavity, the hot air will circulate in the cooking cavity, so that the food is heated from multiple sides, achieving uniform heating.
[0005] Preferably, the rotating mechanism is movably provided with a support member for supporting the food. When the support member is placed on the rotating mechanism, a gap is left between the food and the rotating mechanism, so that hot air can flow into the gap and heat the food from the bottom.
[0006] The exhaust mechanism can draw outside air into the pot body and carry away the heat generated by the rotating mechanism and the uniform heating mechanism during operation, thereby cooling and dissipating heat from the rotating mechanism and the uniform heating mechanism.
[0007] Preferably, the exhaust mechanism is provided with a slot and a fixing post, and the uniform heating mechanism is provided with a second protrusion and a fixing hole that respectively cooperate with the slot and the fixing post, so as to realize the connection between the exhaust mechanism and the uniform heating mechanism.
[0008] Preferably, the rotating mechanism includes a second motor, and the pot body is provided with a motor mounting position. The second motor is mounted in the motor mounting position and is provided with a mounting plate. The mounting plate enables the connection between the second motor and the inner pot. The second motor is provided with a rotating shaft, which extends through the center of the inner pot into the cooking cavity. A turntable is mounted on the rotating shaft, and the support member is placed on the turntable. By driving the second motor, the rotating shaft of the second motor can drive the turntable to rotate around the center of the inner pot, so that the food placed on the support member is rotated and heated in the cooking cavity.
[0009] Preferably, the uniform heating mechanism includes a flow channel formed on the inner pot. A ventilation screen is installed in the flow channel to block oil stains. A heating shell is installed on the inner pot outside the ventilation screen. A mounting sleeve is installed on the heating shell, and a first motor is mounted on the mounting sleeve. The first motor has a rotating shaft that passes through the mounting sleeve and enters the heating shell. A fan blade is mounted on the rotating shaft of the first motor. A heating tube for heating air is installed on the heating shell. By driving the first motor and the heating tube to work simultaneously, the rotating shaft of the first motor drives the fan blade to rotate, causing the air in the cooking cavity to circulate internally. Simultaneously, the heating tube heats the air flowing near the flow channel, thus allowing hot air to circulate within the cooking cavity and heat the food.
[0010] It's worth mentioning that the hot air circulates in the enclosed space, blowing away the moisture on the surface of the food. At the same time, the food's own oil is used to fry the food, causing it to dehydrate and turn golden and crispy, achieving the effect of frying. This process is similar to baking, but due to the action of the fan blades, the food can more easily receive even heat, resulting in better cooking results.
[0011] Preferably, the heating shell is provided with screw holes for mounting. After the mounting sleeve is fitted onto the heating shell, the mounting sleeve and the heating shell are fixed together by screws inserted into the screw holes. The mounting sleeve is provided with a fixing seat, and the first motor can be mounted on the fixing seat by bolts, thereby realizing the connection between the first motor and the first vent hole. The pot body is provided with a notch, and the mounting sleeve is provided with an upper positioning piece that mates with the notch. The mounting sleeve is provided with a lower positioning piece that mates with the pot body. When the mounting sleeve needs to be connected to the pot body, the upper positioning piece can be inserted into the notch, and the lower positioning piece will stick to the bottom of the pot body to realize the positioning and installation between the mounting sleeve and the pot body.
[0012] Preferably, the heating shell is provided with a second vent hole, and the mounting sleeve is provided with a first vent hole at a position corresponding to the heating shell. When the food in the cooking chamber is being heated, in order to maintain the balance of heat and pressure inside the cooking chamber, a small amount of air can be discharged through the second vent hole and the first vent hole to release pressure and ensure the normal operation of the cooking chamber.
[0013] Preferably, the exhaust mechanism includes an exhaust hood, which is mounted on the mounting housing. The tail of the first motor passes through the mounting housing and is fitted with exhaust blades. An exhaust cover is mounted on the exhaust hood. After the exhaust hood and the exhaust cover are assembled, an exhaust groove is formed between the interior of the exhaust hood and the exhaust cover. The exhaust blades are located in the exhaust groove. An exhaust channel is formed between the top of the exhaust hood and the exhaust cover. When the first motor is working, it will drive the exhaust blades to rotate synchronously, so that the heat in the pot enters the exhaust groove and is then discharged upward through the exhaust channel.
[0014] Preferably, the exhaust hood is provided with a fixing post, and the mounting sleeve is provided with a fixing hole that mates with the fixing post, so that the bottom of the exhaust hood and the mounting sleeve are fixed by bolts inserted through the fixing post and fixing hole. The exhaust hood has a slot, and the mounting sleeve has a second protrusion, so that the top of the exhaust hood and the mounting sleeve are fixed through the slot and the second protrusion. The exhaust hood has a third vent hole. When the exhaust hood and the mounting sleeve are installed, the third vent hole is located above the second vent hole and the first vent hole, and the third vent hole communicates with the second vent hole and the first vent hole, allowing hot air to pass through the third vent hole. The exhaust hood is equipped with a first protrusion, and the exhaust cover is equipped with a retaining plate that mates with the first protrusion. The exhaust hood and the exhaust cover are connected and fixed by the first protrusion and the retaining plate. The exhaust cover is equipped with a connecting seat. The pot body is equipped with a cover plate that presses the inner pot. The cover plate is equipped with a pin that mates with the connecting seat. When the cover plate is installed on the pot body, the pin will be inserted into the connecting seat. The pin and the connecting seat are fixed by bolts. The bottom and sides of the pot body are equipped with air inlets for air intake, and the top rear end of the pot body is equipped with an exhaust port for air exhaust. The third vent is connected to the exhaust port.
[0015] It is worth mentioning that the support components in the cooking cavity can also be selectively replaced according to cooking needs, and can be frying baskets, frying buckets, etc.
[0016] Preferably, the pot body is provided with a fixing mechanism, which includes a mounting base installed in the pot body. A rotating plate is rotatably mounted on the mounting base. A return spring is installed between the rotating plate and the inner pot. The return spring can always push the rotating plate. A hook extending into the pot lid is provided on the rotating plate. A hook groove that cooperates with the hook is opened in the pot lid, so that the pot body and the pot lid are locked together by the cooperation of the hook and the hook groove. An opening button is provided on the rotating plate, which extends through the outside of the pot body. By pressing the opening button, the rotating plate is pushed to rotate around the mounting base, and the return spring is squeezed to disengage the hook from the hook groove, so that the pot lid can be flipped open on the pot body.
[0017] Preferably, the pot body is provided with a mounting column, and a connecting column is installed on the mounting column. The connecting column is connected to the inner pot. The installation between the inner pot and the pot body can be completed by connecting the connecting column and the mounting column.
[0018] Preferably, the lid is provided with a viewing window, through which the user can observe the heating status of the food in the cooking cavity. The lid is also provided with a light, which can be driven to illuminate the cooking cavity, allowing the user to view the food in the cooking cavity more clearly through the viewing window. The lid is also provided with a micro switch.
[0019] It's worth mentioning that when the user starts the air fryer via the control panel, the micro switch connects the circuit, and the air fryer begins to heat up. Once the preset temperature is reached, the micro switch automatically disconnects the circuit to prevent overheating or burning of food, ensuring the safety and performance of the air fryer.
[0020] The specific principle of uniform heating of food:
[0021] First, after rotating the lid to close with the pot body, set the cooking mode, time, temperature and other parameters through the control panel. Then, drive the second motor through the control panel. The rotating shaft of the second motor drives the turntable to rotate around the center of the inner pot, so that the food placed on the support rotates in the cooking cavity.
[0022] Synchronous operation is achieved by driving the first motor and heating element to work simultaneously via the control panel. The rotating shaft of the first motor drives the fan blades to rotate, causing the air in the cooking cavity to circulate internally. At the same time, the heating element heats the air flowing near the flow channel, thus allowing the hot air to circulate in the cooking cavity and evenly heat the food that is rotating on the support.
[0023] While heating, ambient air enters through the air inlets at the bottom and sides of the pot. When the ambient air enters the pot, it first dissipates heat from the second motor, lowering its temperature. Then, under the action of the exhaust blades, it also carries away the heat between the pot body and the inner pot, entering the exhaust channel between the heating shell and the exhaust cover. At the same time, when it passes through the first motor, it also dissipates heat from the first motor, lowering its temperature. Then, under the suction of the exhaust blades, it enters the exhaust port through the third vent and is discharged. The heat in the cooking cavity is also discharged through the exhaust port through the second vent and the first vent.
[0024] The control panel, located in the lid, activates the uniform heating mechanism, which allows hot air to circulate within the cooking cavity and, in conjunction with the rotating mechanism, ensures even heating of the food placed on the support.
[0025] Compared with the prior art, the advantages of this utility model are as follows:
[0026] 1. The second motor and turntable can drive the support to rotate, so that the position of the food in the cooking cavity is relatively moved. During the rotation, multiple sides of the food will approach the air source, so that the food can be evenly exposed to air from multiple sides.
[0027] 2. By setting the heating tube, first motor and fan blades and other heating and blowing structures on the side of the pot, side blowing and heating of food is formed, and the air is blown at an angle higher than the food, so that hot air can be blown directly to food of different sizes. When the food rotates in the cooking cavity, the hot air flowing into the cooking cavity will form an internal circulation, heating the food evenly, increasing the air-receiving area of the food and improving the heating efficiency of the food.
[0028] 3. By using the exhaust blades installed on the first motor, the exhaust blades can be started to rotate while heating, allowing ambient air to enter the pot body through the air inlet. The air can enter the exhaust channel between the heating shell and the exhaust hood. During the flow, the air will dissipate heat from the second motor and the first motor, reducing their temperature. This is because motors generate heat during long-term use, and prolonged high-temperature operation will reduce the lifespan of the motors.
[0029] 4. The pot body, heating shell, mounting sleeve, first motor, exhaust hood and exhaust cover can be assembled in sequence, which shortens the assembly time during production, improves assembly efficiency, and forms a uniform heating mechanism and an exhaust mechanism after assembly. The uniform heating mechanism and the exhaust mechanism can be assembled into one unit, which greatly reduces the pot body space occupied by the heating and exhaust functions and makes reasonable use of space.
[0030] 5. The side-blowing heating method also saves space on the lid, increases the visible range of the lid, and makes it easier to clean the lid later. Attached Figure Description

The pot lid 2 is provided with a micro switch 13.
[0044] It is worth mentioning that when the user starts the air fryer through the control panel 11, the micro switch 13 connects the circuit and the air fryer starts heating. When the preset temperature is reached, the micro switch 13 will automatically disconnect the circuit to avoid overheating or burning the food, thus ensuring the safety and operation of the air fryer.
[0045] Furthermore, a fixing mechanism 4 is provided on the pot body 1. The fixing mechanism 4 includes a mounting base 41, which is installed in the pot body 1. A rotating plate 42 is rotatably mounted on the mounting base 41. A return spring 43 is installed between the rotating plate 42 and the inner pot 3. The return spring 43 can always push the rotating plate 42. A hook 44 extending into the pot lid 2 is provided on the rotating plate 42. A hook groove 45 that cooperates with the hook 44 is opened in the pot lid 2, so that the pot body 1 and the pot lid 2 are closed and fixed through the cooperation of the hook 44 and the hook groove 45. An opening button 46 is provided on the rotating plate 42, which extends through to the outside of the pot body 1. By pressing the opening button 46, the rotating plate 42 can be pushed to rotate around the mounting base 41 and squeeze the return spring 43 to disengage the hook 44 from the hook groove 45, so that the pot lid 2 can be flipped open on the pot body 1.
[0046] Furthermore, the rotating mechanism 7 includes a second motor 71. A motor mounting position 15 is provided on the pot body 1, and the second motor 71 is mounted in the motor mounting position 15. A mounting plate 73 is provided on the second motor 71, which enables the connection between the second motor 71 and the inner pot 3. A rotating shaft is provided on the second motor 71, which extends through the center of the inner pot 3 into the cooking cavity 6. A turntable 72 is mounted on the rotating shaft, and the support member 14 is placed on the turntable 72. By driving the second motor 71 to work, the rotating shaft of the second motor 71 can drive the turntable 72 to rotate around the center of the inner pot 3, so that the food placed on the support member 14 is rotated and heated in the cooking cavity 6.
[0047] Furthermore, the uniform heating mechanism 5 includes a heating shell 52. The inner pot 3 has a flow groove 27, and a ventilation screen 28 that can block oil stains is installed in the flow groove 27. The heating shell 52 is installed outside the ventilation screen 28. An installation sleeve 53 is installed on the heating shell 52. A first motor 51 is installed on the installation sleeve 53. The first motor 51 is provided with a rotating shaft. The rotating shaft of the first motor 51 passes through the installation sleeve 53 and enters the heating shell 52. A fan blade 54 is installed on the rotating shaft of the first motor 51. A heating tube 55 that can heat the air is installed on the heating shell 52. By driving the first motor 51 and the heating tube 55 to work simultaneously, the rotating shaft of the first motor 51 drives the fan blade 54 to rotate, so that the air in the cooking cavity 6 circulates internally. At the same time, the heating tube 55 can heat the air flowing to the vicinity of the flow groove 27, so that the hot air circulates in the cooking cavity 6 and heats the food.
[0048] It is worth mentioning that hot air circulates in the enclosed space, blowing away the moisture on the surface of the food. At the same time, the food's own oil is used to fry the food, causing it to dehydrate and turn golden and crispy, achieving the effect of frying. This process is similar to baking, but due to the action of the fan blades, the food can more easily receive even heat, resulting in better cooking results.
[0049] Furthermore, the heating shell 52 is provided with a screw hole mounting position 511. After the mounting sleeve 53 is fitted onto the heating shell 52, the mounting sleeve 53 and the heating shell 52 are fixed by screws inserted into the screw hole mounting position 511.

[0050] Furthermore, a second vent 513 is provided on the heating shell 52, and a first vent 512 is provided on the mounting sleeve 53 at a position corresponding to the heating shell 52. When the food in the cooking chamber 6 is being heated, in order to maintain the balance of heat and pressure inside the cooking chamber 6, a small amount of air can be discharged through the second vent 513 and the first vent 512 to release pressure and ensure the normal operation of the cooking chamber.
[0051] Furthermore, the exhaust mechanism 18 includes an exhaust hood 181, which is mounted on the mounting housing 53. The tail of the first motor 51 passes through the mounting housing 53 and is fitted with an exhaust blade 185. An exhaust cover 182 is mounted on the exhaust hood 181. After the exhaust hood 181 and the exhaust cover 182 are assembled, an exhaust groove 186 is formed between the interiors of the exhaust hood 181 and the exhaust cover 182. The exhaust blade 185 is located in the exhaust groove 186. An exhaust channel 24 is formed between the tops of the exhaust hood 181 and the exhaust cover 182. When the first motor 51 is working, it will drive the exhaust blade 185 to rotate synchronously, so that the heat in the pot body 1 enters the exhaust groove 186 and is then discharged upward through the exhaust channel 24.
[0052] It is worth mentioning that the first motor 51 is provided with a shaft end and a tail end. After the first motor 51 is fixed on the mounting sleeve 53, both the shaft end and the tail end of the first motor 51 can rotate.
[0053] Furthermore, the exhaust hood 181 is provided with a fixing post 20, and the mounting sleeve 53 is provided with a fixing hole 21 that mates with the fixing post 20, so that the bottom of the exhaust hood 181 and the mounting sleeve 53 are fixed by bolts inserted through the fixing post 20 and the fixing hole 21. The exhaust hood 181 is provided with a slot 23, and the mounting sleeve 53 is provided with a second protrusion 22, so that the top of the exhaust hood 181 and the mounting sleeve 53 are fixed through the slot 23 and the second protrusion 22. The exhaust hood 181 is provided with a third vent hole 29. When the exhaust hood 181 and the mounting sleeve 53 are installed, the third vent hole 29 is located between the second vent hole 513 and the first vent hole 512. The top of the vent is connected to the second vent 513 and the first vent 512, allowing hot air to be discharged through the third vent 29. The vent cover 181 is provided with a first protrusion 184, and the vent cover 182 is provided with a retaining plate 183 that cooperates with the first protrusion 184. The vent cover 181 and the vent cover 182 are connected and fixed by the first protrusion 184 and the retaining plate 183. The vent cover 182 is provided with a connecting seat 19, and the cover plate 26 is provided with a pin 25 that cooperates with the connecting seat 19. When the cover plate 26 is installed on the pot body 1, the pin 25 will be inserted into the connecting seat 19, and the pin 25 and the connecting seat 19 will be fixed by bolts.
[0054] Furthermore, the bottom and sides of the pot body 1 are provided with air inlets 8 for air intake, and the top rear end of the cover plate 26 is provided with an exhaust port 9 for exhaust. The third vent 29 is connected to the exhaust port 9. When the first motor 51 is working, the tail end of the first motor 51 will drive the exhaust blade 185 to rotate, so that the ambient temperature air enters through the air inlets 8 on the bottom and sides of the pot body 1. When the ambient temperature air enters the pot body 1, it will first dissipate heat from the second motor 71, reducing the temperature of the second motor 71. Then, under the action of the exhaust blade 185, it will also carry away the heat between the pot body 1 and the inner pot 3, and enter the exhaust groove 186 from between the heating shell 52 and the exhaust cover 181. At the same time, when passing through the first motor 51, it will also dissipate heat from the first motor 51, reducing the temperature of the first motor 51. Then, under the suction of the exhaust blade 185, it will enter the exhaust port 9 from the third vent 29 and be discharged.
[0055] It is worth mentioning that the support component 14 in the cooking cavity 6 can also be selectively replaced according to cooking needs, and can be a frying basket, frying bucket, etc.
[0056] The specific principle of uniform heating of food:
[0057] First, after rotating the lid 2 to close with the pot body 1, set the cooking mode, time, temperature and other parameters through the control panel 11. Then, drive the second motor 71 through the control panel 11 to work. The rotating shaft of the second motor 71 drives the turntable 72 to rotate around the center of the inner pot 3, so that the food placed on the support 14 rotates in the cooking cavity 6.
[0058] Synchronously, the first motor 51 and the heating tube 55 are driven to work simultaneously through the control panel 11. The rotating shaft of the first motor 51 drives the fan blade 54 to rotate, so that the air in the cooking cavity 6 can flow in an internal circulation. At the same time, the heating tube 55 can heat the air flowing to the vicinity of the flow groove 27, so that the hot air flows in an internal circulation in the cooking cavity 6, and evenly heats the food that is rotating on the support 14 placed on the pot body 1.
[0059] While heating, ambient air enters through the air inlets 8 at the bottom and sides of the pot body 1. When the ambient air enters the pot body 1, it first dissipates heat from the second motor 71, reducing its temperature. Then, under the action of the exhaust blades 185, it also carries away the heat between the pot body 1 and the inner pot 3, entering the exhaust groove 186 between the heating shell 52 and the exhaust cover 181. At the same time, when passing through the first motor 51, it also dissipates heat from the first motor 51, reducing its temperature. Then, under the suction of the exhaust blades 185, it enters the exhaust port 9 through the third vent 29 and is discharged.
