Description

Technical Field

[0001] This utility model relates to the field of air outlet guiding assembly technology, and in particular to an air guide mechanism for cooking utensils. Background Technology

[0002] Airflow guiding structures are typically installed inside the outer casing of cooking appliances, primarily to release and disperse heat during cooking, preventing heat buildup that could reduce the quality of the food. However, in existing airflow guiding structures, to ensure installation strength, a baffle is usually installed at the very top of the air outlet to improve overall assembly strength. But this baffle obstructs the airflow, affecting its effectiveness. Utility Model Content

[0003] The purpose of this utility model is to provide a wind guide mechanism for cooking utensils, which improves the overall air outlet efficiency by adjusting the air outlet guide structure and changing its guide path, thereby increasing the overall assembly strength.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] Air guide mechanisms for cooking appliances, including,

[0006] An assembly housing, wherein the assembly housing forms an assembly notch;

[0007] An air outlet mechanism forms an assembly path along the downward assembly notch inside the assembly housing, and several air outlet plates form several air outlet guide tracks from inside the assembly housing to outside the assembly housing.

[0008] The air outlet mechanism is provided with an assembly part that is assembled with the inside of the assembly shell. The first end of the topmost air outlet plate is connected to the first end of the assembly part to form an integrated structure.

[0009] A support is provided at the second end of the topmost air outlet fin, and a baffle is provided on the outside of the support to fit the assembly shell.

[0010] Furthermore, the air outlet mechanism forms an assembly cavity, and a plurality of air outlet vanes are disposed within the assembly cavity, with the plurality of air outlet vanes forming an upwardly inclined guide path in parallel.

[0011] Furthermore, the air outlet fin and the extension line of the assembly part form an angle of 20°-45°.

[0012] Furthermore, the assembly cavity also includes a base, the projection of the assembly part is located on the base, and an inclined surface is formed between the second end of the assembly part and the end of the base away from the air outlet plate.

[0013] Furthermore, it also includes a bottom shell connected to the base and the mounting shell, wherein a motor and a motor support are disposed inside the bottom shell, and the side of the motor support is in contact with the inclined surface.

[0014] Furthermore, among the aforementioned air outlet fins, the gap between adjacent air outlet fins is 5mm-8mm.

[0015] Furthermore, the assembly housing is provided with a fastening screw above the assembly part, and the fastening screw abuts against the assembly part.

[0016] Furthermore, the support portion has a cross-shaped structure, and the baffle is offset inside the cross-shaped structure, with the height of the baffle being at least 3mm higher than the baffle.

[0017] Furthermore, the end of the assembly shell is provided with a snap fastener, and the assembly shell is snapped into the cross-shaped structure by the snap fastener.

[0018] Furthermore, the length of the engagement surface between the buckle and the cross-shaped structure is 0.6-1mm.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this invention, the air outlet guide trajectory is used to allow the hot air inside the cooking appliance to flow out more efficiently. At the same time, the integrated connection between the assembly part and the air outlet plate ensures that there is no obstruction between the two, and the airflow directly enters the air outlet guide trajectory along the assembly surface and flows out, thereby improving the ventilation effect.

[0021] In this invention, the addition of baffles provides a certain support when the assembly shell deforms inward under stress. Consequently, for the assembly shell with an internal cavity, the baffles not only make the assembly at the assembly notch more secure but also increase its strength. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0033] See attached document Figure 1 As shown, in the prior art, the partial intersection between the assembly part 220 and the air outlet fin 210 causes the assembly part to block the air outlet fin, and the airflow enters the intersection during the flow, thus failing to be discharged in time and affecting the heat dissipation effect.

[0034] See attached document Figure 2-8 As shown, the air guide mechanism for cooking appliances includes an assembly shell 100, which forms an assembly notch 110. In this embodiment, the assembly shell 100 can be provided with two or more assembly notches on the same side to complete the assembly of two air outlet mechanisms.

[0035] In this embodiment, the air outlet mechanism 200 forms an assembly path from the inside to the outside along the direction of the downward assembly notch 200 inside the assembly shell 100. Furthermore, the air outlet mechanism 200 forms several air outlet guide tracks from the inside of the assembly shell 100 to the outside of the assembly shell 100 through several air outlet plates 210. Thus, during assembly, the air outlet mechanism 200 is assembled from the inside to the outside, rather than the conventional assembly method from the outside.

[0036] In this embodiment, an assembly part 220 is provided on the air outlet mechanism 200 to be assembled with the inside of the assembly shell 100. The first end of the topmost air outlet slab 210 is connected to the first end of the assembly part 220 to form an integrated structure. Compared with the cross-staggered arrangement in the prior art, the direct connection here forms a good transition surface, avoids the interference of the assembly part with the air outlet slab 210, and ensures that hot air and other air can all flow out.

[0037] In this embodiment, a support portion 230 is provided at the second end of the topmost air outlet fin 210, and a baffle 240 is provided on the outer side of the support portion 230 to fit against the assembly shell 100. In this embodiment, the baffle 240 forms internal support, thereby increasing the strength of the inner side of the assembly shell 100 and making it more resistant to external forces. In this embodiment, the baffle 240 can also restrict the entire assembly shell 100 from making certain movements.

[0038] Furthermore, to complete the assembly of the air outlet slabs 210, the air outlet mechanism 200 forms an assembly cavity, within which a plurality of air outlet slabs 210 are arranged, forming parallel upward-sloping guide paths. Hot air, etc., then flows through the assembly housing 100 along these guide paths, exiting the housing 100 with an upward-sloping trajectory. In this embodiment, the upward slope is formed from the inside of the assembly housing outwards.

[0039] In this embodiment, if the trajectory is inclined upwards from the outside to the inside, and the air is discharged directly backwards or downwards, it is easy to cause the temperature of some cooking appliances such as air fryers to exceed the limit, resulting in the product failing the temperature rise test.

[0040] In this embodiment, the extension line of the air outlet 210 and the assembly part 220 forms an angle of 20°-45°. This smaller angle helps the airflow to turn smoothly and reduces the generation of vortices.

[0041] Specifically, other structures are provided inside the assembly housing 100. At this time, a base 250 is provided at the bottom of the assembly cavity formed by the air outlet mechanism 200. The length of the assembly part 220 is longer, and the projection of the assembly part 220 is located on the base 250. Then, an inclined surface is formed between the second end of the assembly part 220 and the end of the base 250 away from the air outlet plate 210.

[0042] In this embodiment, the interior of the assembly shell 100 is also an assembly space. Its bottom is connected via a bottom shell 300, and the base 250 is also supported on the bottom shell 300. A motor 310 and a motor support 320 are located on the bottom shell 300, forming a drive mechanism. The inclined surface can fit against the side of the motor support, allowing the motor support to form a limiting assembly for the air outlet mechanism. The inclined surface also allows the motor support to be properly tilted during assembly. In this embodiment, after the air outlet mechanism is assembled with the assembly shell, pressing down directly assembles it with the motor support.

[0043] In this embodiment, the gap between adjacent air outlet fins 210 is 5mm-8mm. This spacing ensures sufficient blocking area to change the airflow direction, while the spacing between the baffles does not exceed 8mm to prevent fingers or other objects from getting stuck and affecting use.

[0044] For secure connection, a fastening screw 120 is provided above the assembly part 220 on the assembly housing 100, and the fastening screw 120 abuts against the assembly part 220. This generates a downward force, causing the assembly part to be fixed and tightened. In this embodiment, after the fastening screw is fixed, the upper and lower limits of the air outlet are maintained.

[0045] In this embodiment, the support portion 230 has a cross-shaped structure, and the baffle 240 is offset inside the cross-shaped structure, so that the baffle 240 is located on the support surface formed by the cross-shaped structure, and the height of the baffle 240 is at least 3mm higher than the cross-shaped structure. This results in more contact surface with the assembly shell. In this embodiment, the cross-shaped structure restricts the assembly shell 100 from falling outwards.

[0046] To facilitate assembly, the assembly shell 100 is provided with a buckle 130 at its end, and the assembly shell 100 is snapped into the cross-shaped structure by the buckle 130.

[0047] Specifically, the length of the engagement surface between the buckle 130 on the assembly shell 100 and the cross-shaped structure is 0.6-1 mm. In this embodiment, at least four buckles are provided inside the assembly shell 100. When the length of the buckle engagement surface is 0.6-1 mm, the reliability of pre-assembly and the convenience of assembly can be ensured. In this embodiment, buckles are used to secure the assembly from the inside out, reducing screw assembly and achieving cost reduction.

[0048] In this embodiment, the air outlet mechanism 200 has at least two reserved assembly ports on its outer periphery, which are then used to fix it to the assembly shell.

[0049] The air guiding mechanism in this invention is suitable for all cooking appliances with air outlets, especially air fryers. It can set a full circle of stop ribs at the assembly notch to support the placement of the top cover (i.e., the assembly shell) while preventing the air outlet from being misplaced outside the top cover.

[0050] In this embodiment, the air guide mechanism reduces interference from the support ribs and ensures smooth airflow from the top because the support part and the air outlet are directly connected. At the same time, it forms an upward airflow trajectory, which can reduce the temperature rise at the bottom. Combined with fasteners, it improves the installation effect.

All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
