TECHNICAL FIELD
[0001] The present application relates to the technical field of kitchen cooking appliances, in particular to a dry-burning-preventing air fryer. BACKGROUND
[0002] Air fryers have become one of the core appliances in modern family kitchens due to their healthy and efficient cooking advantages. The working principle of air fryers is to generate hot air through a heating mechanism, which circulates in a closed containment cavity to achieve food frying. Therefore, the sealing performance of the containment cavity and the positioning accuracy of the inner pot directly affect the cooking safety and effect.
[0003] Currently, the air fryers on the market generally have safety protection shortcomings: first, there is a lack of reliable inner pot positioning detection mechanism. When the inner pot is not completely pushed into the containment cavity and the side cover is not closed in place, the device can still start heating, which leads to poor sealing of the containment cavity, large leakage of hot air, energy waste, and direct dry burning of the heating mechanism that is not blocked by the inner pot, which can easily cause component aging and damage due to high local temperature, and even pose a fire hazard.
[0004] To address the above problems, there is an urgent need in the industry for an air fryer with pre-position dry-burning protection. By optimizing the inner pot positioning structure and detection mechanism, the accurate identification of the inner pot positioning state is achieved, and heating is only allowed when the inner pot is completely in place, which eliminates dry burning and heat loss from the source and ensures convenient operation to meet the core needs of safety and efficiency for home cooking.

[0027] See Figures 1-10An embodiment of the present invention provides an anti-dry-burning air fryer, comprising an outer pot body 1 and an inner pot 4. The outer pot body 1 has an installation cavity 11 and a receiving cavity 12. One side of the outer wall of the outer pot body 1 has a loading / unloading port communicating with the receiving cavity 12. The inner pot 4 is located in the receiving cavity 12. A heating mechanism 2 is provided in the installation cavity 11. The inner pot 4 includes a frying basket 41 and a side cover 42. The side cover 42 is used to block the loading / unloading port. A partition is provided at the bottom of the receiving cavity 12, and a positioning component 13 is provided in the partition to determine the position of the inner pot 4. The positioning component 13 includes an installation block 131 disposed in the partition, and a contact element penetrating the partition is movably installed in the installation block 131. The rod 132 has its top end located in the accommodating cavity 12. The mounting block 131 has a groove on its upper surface, and a spring 134 is sleeved on the outside of the rod 132 in the groove. A baffle 137 is fixedly installed on the outer wall of the rod 132 and is located in the groove. The spring 134 is located below the baffle 137. A displacement sensor 133 corresponding to the rod 132 is also provided on the inner wall of the bottom of the partition. A push groove 135 that cooperates with the rod 132 is provided on the bottom of the side cover 42 near the fryer basket 41. A positioning groove 136 that fits with the rod 132 is provided on the bottom of the side cover 42, and the side of the positioning groove 136 near the push groove 135 is provided with a chamfer.
[0028] In this embodiment, addressing the common problems of dry burning and heat loss in existing air fryers due to improper pot placement, this air fryer addresses the issue of the inner pot 4 being pushed into the accommodating cavity 12. When the inner pot 4 is pushed in, the bottom of the side cover 42 contacts the contact rod 132, causing the contact rod 132 to move downwards. This compresses the spring 134 on the outside of the contact rod 132, and the displacement sensor 133 captures the displacement of the contact rod 132. When the side cover 42 closes to the outer pot 1, and the side cover 42 just blocks the opening, the contact rod 132 aligns perfectly with the positioning groove 136 at the bottom of the side cover 42. Under the reset action of the spring 134, the top of the contact rod 132 moves upwards into the positioning groove 136 and abuts against the top of the positioning groove 136, ensuring that the contact rod 132 is in a partially reset state. The displacement of 132 can be captured by displacement sensor 133, indicating that the inner pot 4 is completely located in the accommodating cavity 12. Displacement sensor 133 sends a positioning signal to the control module, at which point the device can start heating to achieve dry-burn protection when the inner pot 4 is not in place. If the inner pot 4 is pulled out during cooking, the contact rod 132 can be triggered again, and the control module can immediately cut off the power to avoid the risk of dry burning and heat loss. At the same time, under the action of the push groove 135, the contact rod 132 can move more smoothly to the bottom of the side cover 42. When the inner pot 4 is taken out, the contact rod 132 can also be smoothly moved out through the chamfered corner of the positioning groove 136 near the push groove 135, which greatly reduces the impact of the contact rod 132 on the taking and putting out of the inner pot 4, resulting in better performance.
[0029] Optional, please refer to Figure 2 , Figure 3 and Figure 4 The heating mechanism 2 includes a drive motor 21 fixedly installed on the inner wall of the top of the mounting cavity 11. The drive end of the drive motor 21 is connected to a rotating shaft, and a centrifugal fan blade 22 is fixedly installed at the end of the rotating shaft. A reflector 23 is fixedly installed in the mounting cavity 11, and the bottom opening of the reflector 23 is connected to the accommodating cavity 12. The rotating shaft passes through the reflector 23, and the centrifugal fan blade 22 is located in the reflector 23. A heating tube 24 is fixedly installed at the top of the accommodating cavity 12, and the heating tube 24 is located below the centrifugal fan blade 22.
[0030] In this embodiment, the drive motor 21 is fixed to the top inner wall of the mounting cavity 11 by bolts, the rotating shaft passes through the center of the reflector 23, and the centrifugal fan blade 22 is fixed to the bottom end of the rotating shaft by a key connection and is located inside the reflector 23; the reflector 23 is fixed to the bottom of the mounting cavity 11 by a bracket, and its lower opening is aligned with the top opening of the accommodating cavity 12; the heating tube 24 is fixed to the top of the accommodating cavity 12 in a ring shape; when the drive motor 21 starts, it drives the centrifugal fan blade 22 to rotate, drawing in the air flowing back from the top of the accommodating cavity 12. The air flows through the ring heating tube 24 and is heated to the set temperature. Under the guidance of the inverted conical reflector 23, a uniform vertical downward hot air is formed, which fully covers the food in the inner pot 4; after the hot air reaches the bottom of the inner pot 4, it flows back up along the side wall of the inner pot 4 and is drawn in again by the centrifugal fan blade 22, forming a closed loop.
[0031] Among them, the vertically downward hot air coverage area reaches 95% of the cross-section of the accommodating cavity 12, and the heating deviation of different parts of the food is ≤5℃; the reflector 23 guides the hot air to concentrate, improving heating efficiency by 30% and shortening cooking time by 30% under the same power; the ring heating tube 24 heats evenly, avoids local overheating, and has a better effect.
[0032] Optional, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 8 The mounting cavity 11 is also provided with a heat dissipation component 3, which is used to dissipate heat from the drive motor 21 and exhaust the fumes generated in the accommodating cavity 12 due to heating food. The heat dissipation component 3 includes a heat dissipation fan blade 31, a heat dissipation port 32 and an exhaust port 33. The heat dissipation fan blade 31 is fixedly installed on the outside of the rotating shaft and is located above the reflector 23. The heat dissipation port 32 is opened on one side of the outer wall of the outer pot body 1 and is connected to the mounting cavity 11. The exhaust port 33 is opened on the side of the reflector 23 near the heat dissipation port 32.
[0033] In this embodiment, the heat dissipation component 3 is integrated into the upper part of the mounting cavity 11, and the heat dissipation fan blade 31 is fixed to the end of the rotating shaft near the drive motor 21, located above the reflector 23; the heat dissipation port 32 is opened on the side of the outer pot body 1 and communicates with the mounting cavity 11; the exhaust port 33 is opened on the side wall of the reflector 23 near the heat dissipation port 32 and connects the interior of the reflector 23 with the mounting cavity 11; when the rotating shaft rotates, it synchronously drives the heat dissipation fan blade 31 to rotate, drawing in external cold air from the heat dissipation port 32, which flows over the surface of the drive motor 21 to dissipate heat, and then the hot air carries the cooking fumes discharged from the accommodating cavity 12 through the exhaust port 33 and is discharged from the heat dissipation port 32 to the outer pot body 1; forming an integrated airflow for air intake, heat dissipation, and smoke exhaust, thereby reducing the operating temperature of the drive motor 21 from 80°C to below 50°C and extending its service life by 2 times; the cooking fumes are discharged in time, and there is no odor residue inside the outer pot body 1, improving the user experience; the heat dissipation and smoke exhaust share a single component, resulting in a compact structure and no additional energy consumption.
[0034] Optional, please refer to Figure 5 , Figure 6 and Figure 7 The inner pot 4 also contains a tray 5, and the four corners of the bottom of the tray 5 are integrally connected with support legs 52. The surface of the tray 5 is provided with several ventilation holes 51.
[0035] In this embodiment, the four bottom support legs 52 are integrally formed with the tray 5, and the ventilation holes 51 are evenly distributed on the surface of the tray 5, covering an area of 30% of the total area of the tray 5. The tray 5 is adapted to the size of the inner pot 4 and can be freely placed in or removed. When in use, the food is placed on the tray 5, and the support legs 52 make the bottom of the tray 5 and the inner pot 4 20mm apart, forming a ventilation gap. The vertically downward hot air passes through the ventilation holes 51 to heat the bottom of the food, avoiding heat accumulation or insufficient heating at the bottom. After passing through the food, the hot air flows back along the side wall of the inner pot 4 to complete the circulation.
[0036] Optional, please refer to Figure 5 , Figure 6 and Figure 7 A first support plate 55 is fixedly installed on one side of the inner wall of the inner pot 4 near the middle position, and a first through-hole 53 corresponding to the first support plate 55 is opened on one side of the tray 5. Two second support plates 56 are symmetrically arranged on the other side of the inner wall of the inner pot 4, and a second through-hole 54 corresponding to the second support plate 56 is opened on the other side of the tray 5. The size of the first support plate 55 and the second support plate 56 is smaller than the first through-hole 53 and the second through-hole 54.
[0037] In this embodiment, the first tray 55 is welded to one side of the inner wall of the inner pot 4, and the second tray 56 is symmetrically welded to the other side of the inner wall. Both the first tray 55 and the second tray 56 are horizontally arranged and have the same height. The position and shape of the first through-hole 53 and the second through-hole 54 of the tray 5 are adapted to the tray, and the size of the tray is 2mm smaller than the through-hole. When placing the tray 5, the first through-hole 53 of the tray 5 is aligned with the first tray 55 and the second through-hole 54 is aligned with the second tray 56, so that the tray 5 can be placed directly on the bottom of the inner pot 4. At the same time, the tray 5 can also be rotated 180 degrees for placement. At this time, the first tray 55 and the second tray 56 can play the role of supporting the tray 5, so that the bottom of the tray 5 has more space, which is more conducive to the air flow at the bottom. With the placement space satisfied, by raising the tray 5, the food on the surface of the tray 5 can be heated more evenly, and the use effect is better.
[0038] Optionally, the tray 5 is also fitted with rubber isolation sheets around its perimeter, the ends of which are in contact with the inside of the inner pot 4, and both the inner pot 4 and the tray 5 are coated with a non-stick coating.
[0039] In this embodiment, the rubber separator is made of food-grade silicone and is fitted around the edges of the tray 5. It is 2mm thick and its end fits tightly against the inner wall of the inner pot 4. Both the inner pot 4 and the tray 5 are coated with a PTFE non-stick coating with a thickness of 20μm. The rubber separator fills the gap between the tray 5 and the inner pot 4, effectively preventing the tray 5 from directly contacting the inner wall of the inner pot 4 and causing wear when the tray 5 is placed, and preventing hot air from escaping through the gap. The non-stick coating makes it difficult for food to stick, and the residue after cooking is easy to wipe off.
[0040] Optional, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The inner walls on both sides of the accommodating cavity 12 are also fixedly installed with limiting plates 6, and the end of the limiting plate 6 facing the loading and unloading port is triangular. The top of the inner pot 4 extends outward, and when the inner pot 4 is pushed into the accommodating cavity 12, the outwardly extending part of the top of the inner pot 4 is located above the limiting plate 6 and just fits against the upper surface of the limiting plate 6.
[0041] In this embodiment, the limiting plate 6 is made of stainless steel and is bolted to the inner walls on both sides of the accommodating cavity 12. The end facing the loading and unloading port is processed into a triangle to facilitate the pushing of the inner pot 4. The top of the inner pot 4 extends outward to form a 5mm wide flange. After being pushed into the accommodating cavity 12, the flange fits against the upper surface of the limiting plate 6. When the inner pot 4 is pushed in, the triangular limiting plate 6 guides the inner pot 4 to be accurately positioned to avoid displacement. It also guides the inner pot 4 to be placed more smoothly in the accommodating cavity 12, resulting in better performance.
[0042] Optionally, please refer to 8. A baffle 7 is also fixedly installed on one side of the outer wall of the outer pot body 1 to make a gap between the fryer and the wall when the fryer is placed. The baffle 7 includes a support rod 71 fixedly installed on one side of the outer wall of the outer pot body 1, and a baffle 72 is fixedly installed at the end of the support rod 71. The upper surface of the baffle 72 is also provided with a slot 73.
[0043] In this embodiment, the support rod 71 is welded to both sides of the back of the outer pot body 1, and the baffle 72 is a rectangular plastic plate that is fixed vertically to the support rod 71. The slot 73 is opened on the upper surface of the baffle 72. When the air fryer is placed next to the wall, the baffle 72 contacts the wall, and the support rod 71 keeps the distance between the outer pot body 1 and the wall 50mm, ensuring smooth ventilation of the heat dissipation vent 32 and the exhaust vent 33. When the air fryer is not in use, the power cord of the air fryer can be directly wrapped around the outside of the support rod 71, and the power plug is snapped into the slot 73, which can achieve a good storage effect and a better usage effect.
[0044] Optionally, a temperature sensor is also provided in the accommodating cavity 12, and the temperature sensor is electrically connected to a controller. The displacement sensor 133, the drive motor 21, and the heating tube 24 are all electrically connected to the controller.
[0045] In this embodiment, a temperature sensor is installed on the side wall of the accommodating cavity 12, with the probe extending into the interior of the accommodating cavity 12 and connected to the controller via a wire. The controller is integrated into the control panel on the front of the outer pot body 1, and can set the temperature (50-230℃) and time (1-60 minutes). The drive motor 21 and the heating element 24 are connected to the controller via a relay. The temperature sensor detects the temperature of the accommodating cavity 12 in real time and transmits the signal to the controller. When the temperature reaches the set value, the controller controls the heating element 24 to cut off the power to keep warm. When the temperature is lower than the set value, the heating element 24 is powered on to heat. After the cooking time is over, the controller cuts off the power to the drive motor 21 and the heating element 24 and issues a prompt sound.
[0046] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
