[0034] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0035] Please also read Figures 1 to 4 The embodiment of the present application provides an air fryer, which includes a shell 10, a cold air hood 20, a driving assembly 30 and a partition 40. The cold air hood 20 is arranged inside the shell 10, and a accommodating chamber 21 is formed inside the cold air hood 20. The outer periphery of the cold air hood 20 is provided with a first opening 201 connected to the accommodating chamber 21. The driving assembly 30 includes a motor 31 and fan blades 32. The motor 31 is installed on the outer side of the cold air hood 20 at the first opening 201, and the fan blades 32 are placed in the accommodating chamber 21 and connected to the output end of the motor 31. When the driving assembly 30 is in operation, the fan blades 32 suck the air outside the cold air hood 20 into the accommodating chamber 21 through the first opening 201. The partition 40 is connected to the outer side of the cold air hood 20, and the partition 40 is arranged along the circumference of the first opening 201 and is arranged around the outer periphery of the motor 31.

[0036] By arranging the shell 10, the cold air hood 20, the drive assembly 30 and the partition 40 to cooperate with each other, the drive assembly 30 can suck the air outside the cold air hood 20 into the accommodating chamber 21 through the first opening 201. The outer power supply machine 31 is installed at the first opening 201 of the cold air hood 20 to accelerate the air flow around the motor 31, so that the motor 31 can generate heat exchange with more air, thereby achieving cooling of the motor 31.

[0037] The heat generated by the motor 31 can also be transferred to the cold air hood 20 by heat conduction, and the heat is discharged from the motor 31 through heat exchange between the cold air hood 20 and the air in the shell 10 to cool the motor 31. The partition 40 is arranged on the outer periphery of the cold air hood 20, which can increase the heat dissipation area of ​​the cold air hood 20 and extend the flow path of the air entering the first opening 201 along the outer periphery of the cold air hood 20, so that the cold air hood 20 can dissipate heat for the motor 31 more efficiently, thereby ensuring the normal operation of the motor 31.

[0038] In application, the shell 10 is mounted on the outer periphery of the cold air hood 20 and a ventilation chamber is formed inside the shell 10. The cold air hood 20, the driving assembly 30 and the partition 40 are all placed in the ventilation chamber. The accommodating chamber 21 is connected to the ventilation chamber. The outer periphery of the shell 10 is also provided with an air inlet 101 and an exhaust port 102 connected to the ventilation chamber. The air outside the air fryer enters the ventilation chamber through the air inlet 101 and is discharged outside the ventilation chamber through the exhaust port 102.

[0039] In application, the shell 10 includes a surrounding wall 11, a bottom plate 12 and a top cover 13. The top cover 13 and the bottom plate 12 are connected to the opposite ends of the surrounding wall 11 along the axial direction of the cold air hood 20 by bolts. The cold air hood 20 is bolted to the inner side of the surrounding wall 11. There are multiple air inlets 101, some of which are opened in the surrounding wall 11, and the other part of the air inlets 101 are opened in the top cover 13.

[0040] Specifically, along the axial direction of the cold air hood 20, a portion of the air inlet 101 opened in the surrounding wall 11 is lower than the partition 40, so that part of the air entering the ventilation chamber needs to flow through the periphery of the cold air hood 20 and the two sides of the partition 40 and enter the accommodating chamber 21 through the first opening 201. The air circulation path is longer and the contact area between the air and the cold air hood 20 is larger, thereby improving the heat dissipation efficiency.

[0041] In application, there are multiple spacers 40 and motors 31 in one-to-one correspondence.

[0042] In one embodiment, please refer to Figures 1 to 4 A ventilation gap 41 is formed between the partition 40 and the motor 31 , and the ventilation gap 41 is connected to the first opening 201 .

[0043] In application, the setting of the ventilation gap 41 can reduce the shielding effect of the motor 31 on the first opening 201, ensure the air intake at the first opening 201, and the air flowing in the ventilation gap 41 can also generate heat exchange with the motor 31 to dissipate heat and cool the motor 31.

[0044] In one embodiment, please refer to Figures 1 to 4 The cold air cover 20 is provided with a connecting portion 22 for installing the power supply machine 31 at the first opening 201 , and the height of the partition 40 is not greater than the height of the motor 31 .

[0045] In application, the height of the partition 40 is not greater than the height of the motor 31 , which can increase the pressure inside the partition 40 to facilitate air to enter the first opening 201 .

[0046] Specifically, in one embodiment of the present application, the connection portion 22 is provided with a bolt hole for bolt connection to the motor 31 . It is understandable that in other embodiments of the present application, the connection portion 22 may also be snap-connected to the motor 31 .

[0047] In one embodiment, please refer to Figures 1 to 4 , the spacer 40 is rectangular.

[0048] In application, one side of the partition 40 is connected to the cold air cover 20 , and the other side extends along the axial direction of the cold air cover 20 in a direction away from the accommodating chamber 21 .

[0049] Specifically, the shape of the spacer 40 is adapted to the shape of the motor 31 installed.

[0050] In one embodiment, please refer to Figures 1 to 4 The spacer 40 is provided with convex strips 42 at intervals.

[0051] In use, the partition 40 is provided with a plurality of ridges 42 at intervals along the circumferential direction, one end of the ridge 42 is located at the edge of the partition 40 away from the cold air hood 20 , and the other end extends to the connection between the partition 40 and the cold air hood 20 .

[0052] In application, the provision of the convex strips 42 can enhance the overall structural strength of the partition 40, reduce the vibration of the partition 40 caused by the wind blowing of the driving assembly 30, and thereby reduce the noise generated by the air fryer during operation.

[0053] In one embodiment, please refer to Figures 1 to 4 The convex strip 42 and the cold air cover 20 are integrally formed.

[0054] In one embodiment, please refer to Figures 1 to 4 The partition 40 and the cold air cover 20 are integrally formed.

[0055] In application, the partition 40 and the cold air cover 20 are integrally injection-molded using a plastic material, so as to facilitate the processing and manufacturing of the partition 40 and the cold air cover 20 and improve the production efficiency.

[0056] In one embodiment, please refer to Figures 1 to 4 A first opening 201 is formed on the top of the cold air cover 20 , and a second opening 202 communicating with the accommodating chamber 21 is formed on the peripheral wall of the cold air cover 20 .

[0057] In application, the cold air hood 20 is a cylindrical volute structure. The cold air hood 20 adopts this shape, which allows the air in the accommodating chamber 21 to flow clockwise or counterclockwise along the circumference of the cold air hood 20, thereby reducing the disturbance and noise of the airflow in the accommodating chamber 21 and improving the flow diversion efficiency.

[0058] In application, an extension portion 23 is formed along the tangential direction of the peripheral wall of the cold air cover 20 . The extension portion 23 is a straight cylindrical box structure. The second opening 202 is opened at the end of the extension portion 23 .

[0059] In application, the extension portion 23 can converge multiple airflows in the accommodating chamber 21 to increase the pressure out of the second opening 202, thereby improving the exhaust efficiency of the cold air hood 20 and making the air flow inside and outside the cold air hood 20 smoother.

[0060] In one embodiment, please refer to Figures 1 to 4 A guide member 50 is further installed on the outer side of the cold air cover 20 at the second opening 202 , and a blocking bar 53 is provided on the guide member 50 to separate the second opening 202 .

[0061] In one embodiment, please refer to Figures 1 to 4 , the blocking bar 53 is arranged along the longitudinal direction.

[0062] In application, the guide member 50 is used to guide the air flowing out of the accommodating chamber 21 from the second opening 202 . The guide member 50 can be made of plastic or alloy. The guide member 50 can be detachably installed at the second opening 202 of the cold air cover 20 .

[0063] Specifically, in one embodiment of the present application, the number of second openings 202 is one, and the number of guide members 50 is the same as the number of second openings 202. It can be understood that in other embodiments of the present application, the number of second openings 202 is at least two, and the number of guide members 50 is the same as the number of second openings 202. Multiple guide members 50 correspond one-to-one with multiple second openings 202, so that it can be applicable to different types of air fryers. The guide member 50 is more versatile, and the guide member 50 can be an independent mounting member or can be integrally formed with the guide member 50.

[0064] In application, the guide member 50 includes an installation frame 51, a fixing plate 52 and a baffle 53. The installation frame 51 is provided with a third opening 501 arranged opposite to the second opening 202. The baffle 53 is connected to the inner periphery of the installation frame 51 and divides the third opening 501. The fixing plate 52 is connected to the side of the installation frame 51 facing the second opening 202.

[0065] Specifically, the air in the accommodating chamber 21 will generate multiple airflows during the continuous circulation process. By setting the baffle 53, the multiple airflows can be diverted at the second opening 202, so that the flow direction of part of the airflow in the accommodating chamber 21 is changed from along the circumference of the cold air hood 20 to along the radial direction of the cold air hood 20. While changing the flow direction, the airflows will also reduce the mutual influence between the airflows. After heat exchange, they will be discharged from the second opening 202 together, so that the exhaust temperature of the air fryer is more uniform, and the melting phenomenon of the shell 10 caused by the high-temperature airflow is reduced. At the same time, the baffle 53 can enhance the overall stability of the guide member 50, and it can remain non-deformed even if the temperature of the second opening 202 is high.

[0066] In application, the third opening 501 is opened in the middle of the installation frame 51, the fixed plate 52 is a ring structure, the baffle 53 is a long sheet structure, the thickness direction of the baffle 53 is perpendicular to the thickness direction of the fixed plate 52, and the structure of the guide member 50 is simple and easy to produce and process.

[0067] Specifically, the mounting frame 51 is provided with a first nut seat on one side of the cold air hood 20 adjacent to the partition 40 in the axial direction, and the fixing plate 52 is provided with second nut seats on opposite sides of the circumference of the cold air hood 20. The cold air hood 20 is provided with a first stud corresponding to the first nut seat, and the cold air hood 20 is also provided with a second stud corresponding to the second nut seat, so that the guide member 50 can be bolted to the cold air hood 20.

[0068] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
