Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to an air fryer. Background Technology

[0002] Air fryers typically have a mounting cavity above the cooking chamber for housing components such as the motor and heating fan. However, during operation, the motor generates heat, and hot air from the cooking chamber also enters the mounting cavity, causing the temperature inside the cavity to rise. This can affect the lifespan of the components and electrical parts within the mounting cavity. Therefore, some air fryers also include a cooling fan inside the mounting cavity to dissipate heat and cool the components.

[0003] In existing technology, a heat dissipation duct is generally constructed by covering the motor inside the mounting cavity at the top of the air fryer, and an air outlet pipe with an air outlet mesh is connected at the air outlet of the heat dissipation duct to discharge the heat dissipation airflow.

[0004] However, in the above solution, the air outlet duct needs to be installed on the main body first, and then the motor cover needs to be assembled with the air outlet duct. The assembly process is cumbersome and inefficient. Furthermore, the connection between the motor cover and the air outlet duct may be poorly sealed due to assembly errors, leading to air leakage at the connection point.

[0005] In addition, the motor cover usually includes a top plate located above the motor and side plates surrounding the motor. Although this improves the protection of the motor and allows the heat dissipation airflow to surround the motor, this structure also increases the difficulty of installing the motor cover and the motor. Because the view is obstructed, it is difficult to position and connect the motor and the motor cover. Utility Model Content

[0006] This invention provides an air fryer to solve the problem of cumbersome assembly steps for the internal motor cover and air outlet duct of existing air fryers.

[0007] The technical solution adopted in this utility model is as follows: An air fryer includes a body with a reflector inside, which divides the internal space into an upper heat dissipation chamber and a lower cooking chamber. A fan assembly is installed inside the heat dissipation chamber, including a drive motor and a cooling fan. A motor bracket is also installed inside the heat dissipation chamber, including a top plate above the cooling fan and an air guide wall surrounding the cooling fan. The top plate and the air guide wall form a heat dissipation duct. The top plate has an upwardly protruding exhaust net. The top wall of the body has a mating opening through which the exhaust net passes. The top wall of the body is at least partially supported by the top plate.

[0008] In this invention, by installing an exhaust screen on the top plate of the motor bracket, the exhaust screen and the top plate are designed as an integrated structure. This allows the heat dissipation duct formed by the top plate and the air guide wall to directly connect with the exhaust screen. This eliminates the need for separate installation of the motor bracket and the exhaust screen, simplifying the assembly process and improving efficiency. Furthermore, it avoids the problem of poor sealing at the joint between the motor bracket and the exhaust screen due to assembly errors, ensuring that the heat dissipation airflow remains within a relatively sealed channel from the heat dissipation duct to the exhaust screen, preventing leakage to the outside. In addition, the exhaust screen has an upward-protruding structure that interlocks with the fitting port on the top wall of the machine body. This interlocking fit facilitates installation and positioning, further reducing the assembly difficulty of the exhaust screen and the machine body and improving assembly efficiency.

[0009] Furthermore, the separate design of the air guide wall and the top plate simplifies the structure of the exhaust network and top plate as a single unit, making it easier to manufacture and reducing production costs. Simultaneously, the separate structure allows for phased installation of the top plate and air guide wall, improving the assembly efficiency of the fan components and electrode supports. For example, the air guide wall can be fixed to the outer periphery of the drive motor, surrounding it. Since the top plate is not yet installed, the top of the cooling duct is open, allowing assembly personnel a clear view for fixing the drive motor and air guide wall. After fixing, the top plate is then placed over the cooling duct from above. Moreover, the top wall of the machine body is at least partially supported by the top plate, which provides sufficient support for the top wall of the machine body, improving the overall reliability of the unit.

[0010] The top wall of the body has a first platform and a second platform. The first platform is lower than the second platform. The mating port is opened on the first platform. There is an installation space between the second platform and the top plate.

[0011] In this design, the first platform on the top wall of the unit is lower than the second platform. The exhaust screen extends from the mating port on the first platform. Because the first platform is lower, it is also closer to the top plate. The exhaust screen only needs to protrude a small distance from the top plate to complete the insertion and mating with the mating port. This shortens the upward protrusion height of the exhaust screen relative to the top plate, thereby shortening the exhaust path and improving exhaust efficiency. Furthermore, the reduced protrusion height also increases the structural strength of the exhaust screen, reducing the possibility of deformation or breakage. The second platform, located at a higher position, provides a larger installation space between itself and the top plate. Therefore, components such as circuit boards can be placed within this installation space, optimizing the internal spatial structure of the unit and contributing to miniaturization.

[0012] The top plate abuts against the first platform to support it.

[0013] In this design, the exhaust net protruding upwards on the top plate passes through the mating port, while the other areas of the top plate abut against the first platform to provide support. Since the top wall of the machine body is usually a thin-walled structure, the support of the top plate can improve the structural strength of the first platform, prevent the first platform from collapsing, and improve the overall quality of the machine.

[0014] The exhaust screen is located at the top rear of the unit, and the air guide wall has a guide section located below the exhaust screen, with a guide arc surface.

[0015] In this design, the rear of the unit is the side away from the user during use. Since the airflow will also heat up upon contact with the hot components inside the cooling chamber, the rear exhaust design keeps the hot airflow away from the user, reducing the risk of burns. Furthermore, the exhaust fan is located on the top wall of the unit, allowing hot air to escape upwards. Compared to horizontal or angled exhaust from the rear, this avoids excessive temperature rise at the rear and eliminates the need for heat insulation columns near the rear, simplifying the internal structure and reducing the overall size of the unit. The airflow direction within the cooling duct is first horizontal from the cooling fan outwards, then upwards below the exhaust fan to the exhaust fan itself. The curved guide surface makes the upward turn of the airflow smoother and more efficient, improving airflow efficiency and thus cooling efficiency. This design also prevents violent collisions between the airflow and the inner wall of the cooling duct during turning, avoiding turbulence that could lead to poor exhaust and noise.

[0016] An air outlet is provided on the side of the reflector facing the airflow guide, and the air outlet is connected to the heat dissipation duct at the airflow guide.

[0017] In this design, the "exhaust gas" inside the cooking cavity is discharged through the air outlet of the reflector. This airflow mixes with the cooling airflow in the heat dissipation duct at the guide section, and under the guidance of the guide section, they flow upward together and are discharged through the exhaust net. The guide section makes the mixing of the two airflows smoother, avoiding violent collisions between airflows flowing in opposite directions that would generate noise. At the same time, the guide section is located downstream of the electrode in the heat dissipation duct, so it mixes with the "exhaust gas" in the cooking cavity here. The high-temperature exhaust gas will not flow to the drive motor, ensuring the cooling effect of the cooling airflow on the drive motor.

[0018] The sidewall of the body has an inwardly recessed portion, and the flow guide portion abuts against the inwardly recessed portion.

[0019] In this design, the guide section abuts against the concave portion of the side wall of the casing, sealing the gap between them. Since the airflow exiting the exhaust screen is at a high temperature and carries a certain amount of moisture, this moisture may condense upon cooling. The abutment between the guide section and the side wall of the casing prevents liquid from flowing through the gap between the exhaust screen and the fitting port to the outside of the heat dissipation duct. Even if liquid enters from the exhaust screen, it can only flow to the side of the guide section facing the heat dissipation duct, i.e., the side where the reflector is located, where it can be promptly eliminated by the high-temperature evaporation of the reflector.

[0020] The body includes a separate head and a base. The head is equipped with an upper coupler, and the base is equipped with a lower coupler. The upper coupler and the lower coupler are coupled together. A reflector is disposed inside the head. A vertical partition is disposed inside the heat dissipation cavity. The partition divides the heat dissipation cavity into a first mounting chamber and a second mounting chamber located on the lateral side of the first mounting chamber. The fan assembly is disposed in the first mounting chamber, and the upper coupler is located in the second mounting chamber.

[0021] In this design, the heat dissipation cavity is horizontally divided into two chambers. The fan assembly is located in the first mounting chamber, and the upper coupler is located in the second mounting chamber. This horizontal arrangement of the two chambers not only makes efficient use of the internal space of the air fryer head but also reduces the overall thickness of the head compared to a vertical arrangement, resulting in a thinner and lighter overall design. Furthermore, during air fryer operation, the first mounting chamber has a higher internal temperature due to the presence of the fan assembly, while the second mounting chamber has a relatively lower temperature. The partition reduces the flow of heat and moisture from the first mounting chamber to the second, lowering the temperature rise in the second mounting chamber where the upper coupler is located and reducing the risk of moisture contact with the upper coupler, thus extending its lifespan. Simultaneously, the exhaust fan faces upwards, and the horizontal arrangement of the first and second mounting chambers ensures that the exhaust direction is away from the second mounting chamber. Since the airflow from the exhaust fan is hot air, this avoids hot air entering the second mounting chamber and causing internal temperature rise.

[0022] The second mounting chamber has an opening that connects to the first mounting chamber, and at least a portion of the air guide wall forms a partition that blocks at least a portion of the opening.

[0023] In this design, the two chambers are connected by an opening. The rotation of the fan assembly in the first mounting chamber generates a cooling airflow, which also enters the second mounting chamber through the opening to provide air cooling for the upper coupler, further reducing the possibility of overheating. Furthermore, because the two chambers are connected by a small-diameter opening, the rapid flow of the cooling air in the first mounting chamber creates a localized low pressure. This pressure draws hot air from the second mounting chamber through the opening, accelerating the heat dissipation from the second mounting chamber and improving the heat dissipation effect of the upper coupler.

[0024] The drive motor is a brushless motor, and it is located inside the cooling air duct.

[0025] In existing technologies, the internal motor of an air fryer is relatively large, making it difficult to place it entirely within the cooling duct formed by the motor support. Often, it is partially located within the cooling duct or completely outside of it. This results in the cooling airflow within the duct not directly contacting the motor for cooling, and also increases the height of the appliance, making it relatively bulky and heavy. In this solution, a brushless motor is used as the drive motor. Its smaller size allows it to be fully placed within the cooling duct, enabling direct airflow contact for improved cooling, while also preventing an excessive increase in the size of the motor support and the appliance itself. This contributes to a compact structure and makes efficient use of the internal space.

[0026] The top wall of the machine body is provided with a first platform, the mating port is opened on the first platform, the top plate is provided with an upward protruding exhaust boss, and the exhaust net is set on the top surface of the exhaust boss and is higher than the first platform.

[0027] In this design, after the exhaust protrusion and the first platform are inserted and fitted together, the exhaust protrusion protrudes from the first platform, causing the exhaust screen to be positioned higher than the top surface of the first platform. This allows liquids, food residues, etc., on the top surface of the first platform to be blocked by the exhaust protrusion, preventing them from entering the machine body through the exhaust screen. Instead, they are kept on the outer surface of the machine body by the exhaust protrusion, making it convenient for users to clean and ensuring the cleanliness of the machine's interior.

[0035] like Figure 1 , Figure 2 , Figure 7 As shown, an air fryer includes a body 1. A reflector 15 is provided inside the body 1, which divides the internal space of the body 1 into an upper heat dissipation cavity 14 and a lower cooking cavity 13. A fan assembly 2 is provided inside the heat dissipation cavity 14, which includes a drive motor 21 and a cooling fan 22. A motor bracket 3 is also provided inside the heat dissipation cavity 14. The motor bracket 3 includes a top plate 33 located above the cooling fan 22 and an air guide wall 34 surrounding the cooling fan 22. The top plate 33 and the air guide wall 34 form a heat dissipation air duct 31. The top plate 33 and the air guide wall 34 are separately provided. The top plate 33 is provided with an upwardly protruding exhaust net 32. The top wall of the body 1 is provided with a mating opening 111, through which the exhaust net 32 ​​passes. The top wall of the body 1 is at least partially supported on the top plate 33.

[0036] It is understandable that the exhaust screen 32 has a mesh structure. It should be noted that in this invention, the top plate 33 is not necessarily a flat plate structure; for example, ... Figure 4 , Figure 5 As shown, it can also be a structure with the edges bent downwards to facilitate splicing with the air guide wall 34.

[0037] In this invention, by setting an exhaust net 32 ​​on the top plate 33 of the motor bracket 3, the exhaust net 32 ​​and the top plate 33 are designed as an integral structure. This also allows the heat dissipation duct 31 formed by the top plate 33 and the air guide wall 34 to directly communicate with the exhaust net 32. On the one hand, this eliminates the step-by-step installation process of the motor bracket 3 and the exhaust net 32, simplifying the assembly steps and improving assembly efficiency. On the other hand, it avoids the problem of poor sealing at the joint between the motor bracket 3 and the exhaust net 32 ​​due to assembly errors, ensuring that the heat dissipation airflow is always in a relatively closed channel from the heat dissipation duct 31 to the exhaust net 32, without leaking to the outside of the heat dissipation duct 31. In addition, the exhaust net 32 ​​has an upward protruding structure, which is inserted into the mating port 111 on the top wall of the body 1. The insertion and mating facilitates installation and positioning. The body 1 can be directly assembled from top to bottom and inserted into the exhaust net 32, thereby further reducing the assembly difficulty of the exhaust net 32 ​​and the body 1 and improving assembly efficiency.

[0038] Furthermore, the separate design of the air guide wall 34 and the top plate 33 simplifies the structure of the exhaust net 32 ​​and the top plate 33 as a single unit, making it easier to manufacture and reducing production costs. Simultaneously, the separate structure allows the top plate 33 and the air guide wall 34 to be installed in stages, improving the assembly efficiency of the fan assembly 2 and the electrode support. For example, the air guide wall 34 can be fixed to the outer periphery of the drive motor 21, surrounding it. At this time, since the top plate 33 is not installed, the top of the heat dissipation duct 31 is open, allowing the assembly personnel a clear view to fix the drive motor 21 and the air guide wall 34. After fixing, the top plate 33 is then placed over the heat dissipation duct 31 from above.

[0039] As a preferred embodiment of this utility model, such as Figure 2 As shown, the top wall of the body 1 has a first platform 112 and a second platform 113. The first platform 112 is lower than the second platform 113. The mating port 111 is opened on the first platform 112. There is an installation space 114 between the second platform 113 and the top plate 33.

[0040] The first platform 112 on the top wall of the body 1 is lower than the second platform 113. The exhaust net 32 ​​extends from the mating port 111 of the first platform 112. Since the height of the first platform 112 is relatively low, it is also closer to the top plate 33. The exhaust net 32 ​​only needs to protrude a small distance from the top plate 33 to complete the insertion and mating with the mating port 111. This shortens the upward protrusion height of the exhaust net 32 ​​relative to the top plate 33, thereby shortening the exhaust path and improving exhaust efficiency. On the other hand, the reduced protrusion height also improves the structural strength of the exhaust net 32, reducing the possibility of deformation or breakage. The second platform 113 is located at a higher position, with a larger installation space 114 between it and the top plate 33. Therefore, components such as circuit boards can be placed in the installation space 114, optimizing the internal space structure of the body 1 and contributing to miniaturization design.

[0041] Preferably, since the second platform 113 is higher than the first platform 112, the second platform 113 can also be designed as a handle structure, allowing the user to lift and remove a portion of the body 1 by gripping the outer periphery of the second platform 113. Because the second platform 113 is higher than the first platform 112, and the exhaust net 32 ​​is located on the first platform 112, when the user grips the second platform 113, the distance from the exhaust net 32 ​​is greater, which can prevent the hot air jets from the exhaust net 32 ​​from scalding the user.

[0042] This embodiment does not limit the transition method between the first platform 112 and the second platform 113. In one embodiment, such as Figure 2 As shown, a vertical wall is provided between the first platform 112 and the second platform 113 to form a stepped structure between them. In another embodiment, the top wall of the body 1 gradually increases in height from the first platform 112 to the second platform 113 to form a sloping structure between them, making the top appearance of the body 1 smoother.

[0043] Furthermore, such as Figure 2 As shown, the top plate 33 abuts against the first platform 112 to support the first platform 112; in a specific embodiment, the top plate 33 is supported by an upwardly protruding support rib 36 provided thereon, which abuts against the first platform 112 to support the first platform 112.

[0044] The exhaust net 32 ​​protruding upward on the top plate 33 passes through the mating port 111, while the other areas of the top plate 33 abut against the first platform 112 and provide support for the first platform 112. Since the top wall of the body 1 is usually a thin-walled structure, the support of the top plate 33 can improve the structural strength of the first platform 112, prevent the first platform 112 from collapsing, and improve the overall quality of the machine.

[0045] The upper surface of the top plate 33 can directly abut against the lower side of the first platform 112 to provide support for the first platform 112. Preferably, as follows... Figure 5 As shown, the upper surface of the top plate 33 is provided with a plurality of upwardly protruding support ribs 36 at intervals, which abut against the first platform 112. Since the top plate 33 forms the top wall of the heat dissipation duct 31, the temperature of the top plate 33 may be relatively high. The abutment between the top plate 33 and the first platform 112 by the support ribs 36 can not only provide good support for the first platform 112, but also appropriately reduce the contact area between the top plate 33 and the first platform 112, reduce the heat transfer from the top plate 33 to the first platform 112, and avoid excessive temperature rise of the first platform 112.

[0046] Preferably, such as Figure 2 As shown, the exhaust net 32 ​​is located on the top rear side of the body 1, and the air guide wall 34 has a guide section 341 located below the exhaust net 32, and the guide section 341 is provided with a guide arc surface.

[0047] The rear side of the unit 1 is the side away from the user during use. Since the temperature rises after the cooling airflow comes into contact with the hot components inside the heat dissipation cavity 14, the rear exhaust design keeps the hot airflow away from the user, reducing the risk of burns. Furthermore, the exhaust fan 32 is located on the top wall of the unit 1, allowing the hot airflow to escape upwards. Compared to horizontal or inclined exhaust from the rear of the unit 1, this avoids excessive temperature rise at the rear and eliminates the need for heat insulation columns near the rear, simplifying the internal structure and reducing the overall size of the unit 1. The cooling airflow within the cooling duct 31 flows horizontally from the cooling fan 22 outwards, then upwards below the exhaust fan 32 to the exhaust fan 32. The curved guide surface makes the upward transition of the airflow smoother and more gentle, improving airflow efficiency and thus cooling efficiency. To avoid the airflow from violently colliding with the inner wall of the heat dissipation duct 31 when it turns, which would create turbulence, resulting in poor exhaust and noise.

[0048] Furthermore, such as Figure 2 As shown, the reflector 15 has an air outlet 151 on the side facing the airflow guide 341, and the air outlet 151 is connected to the heat dissipation air duct 31 at the airflow guide 341.

[0049] The "exhaust gas" inside the cooking cavity 13 is discharged through the air outlet 151 of the reflector 15. This airflow mixes with the cooling airflow in the heat dissipation duct 31 at the guide section 341, and flows upward together under the guidance of the guide section 341, and is discharged through the exhaust net 32. The guide section 341 makes the mixing of the two airflows smoother, avoiding violent collisions between the two airflows with different directions that would generate noise. At the same time, the guide section 341 is located downstream of the electrode in the heat dissipation duct 31, so it mixes with the "exhaust gas" inside the cooking cavity 13 at this point. The high-temperature exhaust gas will not flow to the drive motor 21, ensuring the cooling effect of the cooling airflow on the drive motor 21.

[0050] Specifically, such as Figure 2 As shown, the fan assembly 2 also includes a hot air fan 23. The drive motor 21 and the cooling fan 22 are located within the cooling duct 31, above the reflector 15, while the hot air fan 23 is located below the reflector 15, within the cooking chamber 13. The drive motor 21 simultaneously drives both the cooling fan 22 and the hot air fan 23 to rotate. The cooling fan 22 draws in cool air from the air inlet of the body 1 into the cooling duct 31, cooling the drive motor 21 and other components before exhausting it through the exhaust screen 32. The hot air fan 23 blows heat from the heating components into the cooking chamber 13 to heat the food. The resulting "exhaust gas" is discharged through the air outlet 151. The two airflows mix at the guide section 341 and are discharged upwards through the exhaust screen 32.

[0051] Specifically, the lower end of the air guide wall 34 is fitted with the reflector 15 so that the reflector 15, the air guide wall 34 and the top plate 33 together form a heat dissipation air duct 31.

[0052] Preferably, such as Figure 2 As shown, the side wall of the body 1 has an inwardly recessed portion 19, and the flow guide portion 341 abuts against the inwardly recessed portion 19.

[0053] The guide section 341 abuts against the recessed portion 19 on the side wall of the body 1, sealing the gap between them. Since the airflow discharged from the exhaust net 32 ​​is at a high temperature and carries a certain amount of water vapor, the water vapor may condense and form condensate when it is discharged from the exhaust net 32. The abutment between the guide section 341 and the side wall of the body 1 prevents liquid from flowing to the outside of the heat dissipation duct 31 through the gap between the exhaust net 32 ​​and the mating port 111. Even if liquid enters from the exhaust net 32, it can only flow to the side of the guide section 341 facing the heat dissipation duct 31, that is, the side where the reflector 15 is located, so that it can be promptly eliminated by the high temperature evaporation of the reflector 15.

[0054] It should be noted that this utility model does not limit the model of the air fryer. In one embodiment, the side wall of the body 1 is provided with a loading and unloading port that communicates with the cooking cavity 13. The air fryer also includes a fryer assembly, which can be pulled out of the loading and unloading port into or out of the cooking cavity 13.

[0055] In another implementation, such as Figure 1 , Figure 2 As shown, the machine body 1 includes a separate head 11 and a base 12. The head 11 is provided with an upper coupler 16, and the base 12 is provided with a lower coupler 17. The upper coupler 16 and the lower coupler 17 are coupled together. A reflector 15 is disposed inside the head 11. In this embodiment, a space for placing the pot is formed between the head 11 and the base 12. The cooking cavity 13 is located inside the pot. The head 11 constitutes the lid of the pot. The head 11 can be removed from the base 12 to open the pot. Since the head 11 and the base 12 are separate structures, the circuit is connected through the upper coupler 16 and the lower coupler 17.

[0056] Furthermore, such as Figure 2 As shown, a vertical partition 18 is provided inside the heat dissipation cavity 14. The partition 18 divides the heat dissipation cavity 14 into a first mounting chamber 141 and a second mounting chamber 142 located on the lateral side of the first mounting chamber 141. The fan assembly 2 is located in the first mounting chamber 141, and the upper coupler 16 is located in the second mounting chamber 142.

[0057] In this design, the heat dissipation cavity 14 is laterally divided into two chambers by a partition 18. The fan assembly 2 is located in the first mounting chamber 141, and the upper coupler 16 is located in the second mounting chamber 142. This lateral arrangement of the two chambers not only makes efficient use of the internal space of the air fryer head 11, but also reduces the overall thickness of the head 11 compared to a vertical arrangement, resulting in a thinner and lighter overall design. Furthermore, during air fryer operation, the temperature inside the first mounting chamber 141 is higher due to the presence of the fan assembly 2, while the temperature inside the second mounting chamber 142 is relatively lower. The partition 18 reduces the flow of heat and moisture from the first mounting chamber 141 to the second mounting chamber 142, lowering the temperature rise in the second mounting chamber 142 where the upper coupler 16 is located. It also reduces the risk of moisture contact with the upper coupler 16, thus extending its service life. Meanwhile, the exhaust net 32 ​​faces upward to exhaust air, while the first mounting chamber 141 and the second mounting chamber 142 are arranged horizontally, so that the exhaust direction is away from the second mounting chamber 142. Since the airflow coming out of the exhaust net 32 ​​is hot air with a higher temperature, the exhaust direction being away from the second mounting chamber 142 can prevent hot air from entering the second mounting chamber 142 and causing the internal temperature to rise.

[0058] Preferably, such as Figure 6As shown, the exhaust net 32 ​​has a guide section 341 below it, which forms a partition 18. The guide section 341 can be formed on the top plate 33, or on the air guide wall 34, or it can be set independently relative to the top plate 33 and the air guide wall 34.

[0059] Preferably, such as Figure 2 , Figure 6 As shown, the second mounting chamber 142 has an opening that connects to the first mounting chamber 141, and at least a portion of the air guide wall 34 forms a partition 18 that blocks at least a portion of the opening.

[0060] The two chambers are connected by an opening. Since the fan assembly 2 in the first mounting chamber 141 generates a cooling airflow, this airflow also enters the second mounting chamber 142 through the opening, providing air cooling for the upper coupler 16 and further reducing the possibility of overheating. Furthermore, because the two chambers are connected by a small-diameter opening, the rapid flow of the cooling airflow in the first mounting chamber 141 creates a localized low pressure. This pressure draws hot air from the second mounting chamber 142 through the opening, accelerating the heat dissipation from the second mounting chamber 142 and improving the heat dissipation effect of the upper coupler 16.

[0061] The partition 18 can completely separate the first mounting chamber 141 and the second mounting chamber 142, so that the second mounting chamber 142 constitutes a closed sealed chamber. Preferably, the partition 18 blocks part of the opening so that the opening has a connecting area and a blocking area, wherein the area of ​​the connecting area is smaller than the area of ​​the blocking area.

[0062] Preferably, such as Figure 2 As shown, the second mounting chamber 142 is located behind the first mounting chamber 141. The air guide wall 34 forms a partition 18 in the area behind the corresponding head 11, so that the upper coupler 16 and the exhaust net 32 ​​are both located behind the body 1, and the exhaust position will not interfere with the upper coupler 16, thus optimizing the structural layout of the body 1 and improving the overall aesthetics of the machine.

[0063] Preferably, the drive motor 21 is a brushless motor, such as... Figure 2 , Figure 3 As shown, the drive motor 21 is located inside the heat dissipation duct 31.

[0064] In the prior art, the motor inside the air fryer is relatively large, so it is difficult to place it completely inside the heat dissipation duct 31 formed by the motor bracket 3. It is often partially located inside the heat dissipation duct 31 or completely located outside the heat dissipation duct 31. This makes it difficult for the heat dissipation airflow inside the heat dissipation duct 31 to directly contact the motor to cool it down. It also increases the height of the body 1, making the body 1 relatively thick and heavy.

[0065] In this embodiment, the drive motor 21 is a brushless motor, which is small in size. It can be completely placed in the heat dissipation duct 31 so that the heat dissipation airflow can directly contact it to improve the cooling effect. It will not cause the motor bracket 3 and the body 1 to be too large, which helps to achieve a compact structure and make reasonable use of the internal space of the body 1.

[0066] In a preferred embodiment, such as Figure 2 , Figure 7 As shown, the top wall of the body 1 is provided with a first platform 112, the mating port 111 is opened on the first platform 112, the top plate 33 is provided with an upwardly protruding exhaust boss 35, and the exhaust net 32 ​​is provided on the top surface of the exhaust boss 35 and is higher than the first platform 112.

[0067] After the exhaust protrusion 35 is inserted into the mating port 111 of the first platform 112, the exhaust protrusion 35 protrudes from the first platform 112, making the position of the exhaust net 32 ​​higher than the top surface of the first platform 112. This allows liquids, food residues, etc. on the top surface of the first platform 112 to be blocked by the exhaust protrusion 35, making it difficult for them to enter the interior of the machine body 1 through the exhaust net 32. Instead, they are blocked on the outside of the machine body 1 by the exhaust protrusion 35, which is the outer surface of the machine body 1. This facilitates cleaning by the user and also ensures the cleanliness of the interior of the machine body 1.

[0068] Of course, in other embodiments, the upper surface of the exhaust boss 35 may also be flush with the upper surface of the first platform 112, which is not limited here.
