[0034] As attached Figure 1-5 As shown, this application provides a fan mounting structure for a cooking device through the following technical solution, including:

[0035] Cooking cavity 1, with a protective plate 2 on one side;

[0036] Fan 3, fan blade 31 and motor 32 are located on the inner and outer sides of guard plate 2, fan blade 31 and motor 32 are connected by a rotating shaft 33, the rotating shaft 33 passes through guard plate 2;

[0037] The bracket 4 and the motor 32 are fixedly connected to the guard plate 2 through the bracket 4. The center of the bracket 4 is provided with a first central hole 41 for the shaft 33 to pass through. A metal mesh 42 is provided on the side of the first central hole 41 facing the guard plate 2 to shield microwave leakage from the gap between the shaft 33 and the first central hole 41.

[0038] Compared with the prior art, the metal mesh 42 provided on the side of the first central hole 41 facing the guard plate 2 can shield the microwave leakage in the cooking cavity 1 through the gap between the rotating shaft 33 and the first central hole 41; at the same time, the metal mesh 42 is located on the outside of the guard plate 2, which can reduce the adhesion of water vapor and oil fumes in the cooking cavity 1, and improve the cleanliness and service life of the metal mesh 2.

[0039] In the technical solution of this embodiment, the bracket 4 has a hole seat 43 at its center, and the hole seat 43 has a first central hole 41 at its center. The rotating shaft 33 passes through the first central hole 41 and extends into the guard plate 2 to connect and drive the fan blade 31. A first protruding ring 431 extends circumferentially from the hole seat 43 toward the guard plate 2. The first protruding ring 431 surrounds and forms a groove 432, and the metal mesh 42 is disposed in the groove 432.

[0040] Specifically, the metal mesh 42 has a third central hole 421. The rotating shaft 33 passes through the first central hole 41, then through the third central hole 421, and extends into the protective plate 2. The inner diameter of the third central hole 421 matches the outer diameter of the rotating shaft 33. To facilitate assembly and ensure the rotation of the rotating shaft 33, there needs to be a certain gap between the rotating shaft 33 and the first central hole 41 of the bracket 4. However, since the metal mesh 42 is thin and has a certain degree of deformability, the third central hole 421, even when tightly attached to the rotating shaft 33, will not affect the assembly and rotation of the rotating shaft 33. This effectively shields the gap between the rotating shaft 33 and the first central hole 41 that could cause microwave leakage.

[0041] Specifically, the outer diameter of the metal mesh 42 is matched with the inner diameter of the first convex ring 431, so that the metal mesh 42 can be better fitted and placed in the groove 432, achieving effective positioning of the metal mesh 42 and ensuring long-term effective and reliable cooperation between the metal mesh 42 and the rotating shaft 33.

[0042] In the technical solution of this embodiment, a second central hole 21 is provided at the center of the protective plate 2. The rotating shaft 33 extends from the outside of the protective plate 2 through the second central hole 21 into the cooking cavity 1 inside the protective plate 2, and is connected to drive the fan blade 31. A second protruding ring 22 extends circumferentially from the second central hole 21 toward the hole seat 43, and the end of the second protruding ring 22 presses against the metal mesh 42. The direct pressing of the second protruding ring 22 against the metal mesh 42 forms a complete seal between the second central hole 21 and the first central hole 41 for microwaves, preventing microwaves leaking outward from the gap between the second central hole 21 and the rotating shaft 33; at the same time, the pressing of the second protruding ring 22 further improves the positioning effect of the metal mesh 42, preventing the metal mesh 42 from warping or deforming due to the influence of the rotating shaft 33.

[0043] Specifically, the second convex ring 22 is a conduit, with one end of the conduit snapped into the second central hole 21 and the other end pressed against the metal mesh 42. Using a conduit facilitates the manufacturing and installation of the second convex ring 22. Alternatively, the second convex ring 22 can be bent at the second central hole 21 of the protective plate 2 to form an integral part of the protective plate 2, achieving the same effect.

[0044] In the technical solution of this embodiment, a sealing element 44 is sleeved at the end of the first convex ring 431. The sealing element 44 further includes a first sealing part 441 and a second sealing part 442. The first sealing part 441 abuts against the outer side of the protective plate 2, and the second sealing part 442 abuts against the outer side of the second convex ring 22. Since there are gaps inside the metal mesh 42, the sealing element 44 can prevent water vapor and oil fumes in the cooking cavity 1 from leaking through the metal mesh 42. At the same time, the sealing element 44 is made of elastic material. The first sealing part 441 and the second sealing part 442 abut against the protective plate 2 and the second convex ring 22 respectively, which can improve the elastic shock absorption effect between the bracket 4 and the protective plate 2 and reduce the vibration and noise generated when the motor 32 rotates.

[0045] In addition, since the metal mesh 42 will come into contact with a small amount of moisture and smoke from the cooking cavity 1 exposed through the second central hole 21, the metal mesh 42 is made of a metal that is not easily corroded, such as stainless steel, copper, or aluminum. This can prevent the microwave shielding performance from decreasing due to corrosion of the metal mesh 42.

[0046] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
