[0002] An oven is a sealed appliance used to bake food or dry products. It is divided into household ovens and industrial ovens. The oven body and the oven door are opened and closed by a hinge mechanism. The traditional oven hinge mechanism uses a double-sided bonding method to hinge the hinge parts and the hinge rod. This method makes the contact area between the two larger. As a result, after the product has been used for a certain number of years, the oven door is prone to make abnormal noises when opening and closing relative to the oven body, affecting the user experience. [Utility Model Content]

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] See also Figures 1 to 3A hinge mechanism for preventing abnormal noise includes a hinge 1 and a hinge rod 2 hinged to the hinge 1, wherein the hinge 1 is arranged on a box door 3, and the hinge rod 2 is hinged to a box body 4; or the hinge 1 is arranged on the box body 4, and the hinge rod 2 is hinged to the box door 3, and the hinge rod 2 is in single-sided contact with the hinge 1.

[0022] The hinge mechanism of the present application is a hinge mechanism that prevents abnormal noise. By improving the hinge mechanism of the oven, the connection method between the hinge rod and the hinged part is changed from the traditional double-sided bonding to single-sided contact, which effectively reduces the contact area between the two. When the door and the box body are opened and closed, the friction and wear degree can be reduced, thereby solving the problem in the prior art that after the oven has been used for a certain number of years, the door is prone to make abnormal noises when opening and closing relative to the box body. Therefore, the solution of the present application improves the use experience and durability of the oven and extends the service life of the product.

[0023] Furthermore, as a preferred embodiment of the present invention but not a limitation, a first opening 11 is provided on the hinged component 1, a second opening 21 is provided on the hinged rod 2, and a pivot passes through the first opening 11 and the second opening 21 to hinge the hinged rod 2 and the hinged component 1.

[0024] In this embodiment, the hinge rod and the hinged member are hinged by the pivot passing through the two openings, which provides a simple and effective connection method. The hinge rod can be set above the hinged member or below the hinged member. In addition, the design of the opening can be adjusted, such as replacing pivots of different diameters to adapt to doors or boxes of different thicknesses, which increases the versatility and flexibility of the hinge mechanism. Both can achieve a single-sided hinged form, which not only ensures the smooth opening and closing of the oven door, but also effectively avoids the abnormal noise problem that may occur after long-term use, thereby improving the durability of the product and user experience.

[0025] Furthermore, as a preferred implementation of the present solution but not a limitation, the hinge rod 2 is in contact with the upper surface of the hinge 1 .

[0026] In this embodiment, the overall rigidity of the hinge mechanism is improved, making the door more stable during opening and closing, and reducing noise and vibration that may be generated by loose hinges. In addition, the tightly fitting contact surface also helps to disperse the force borne by the hinge, prolong its service life, and reduce wear.

[0027] Furthermore, as a preferred implementation manner of the present solution but not a limitation, a support platform 12 extending upward is provided on the hinged member 1 corresponding to the hinged portion of the hinged member 1 .

[0028] In this embodiment, the support platform can enhance the structural stability of the hinge, reduce the contact area of ​​the hinge point, and improve the bearing capacity of the hinge mechanism. Secondly, the presence of the support platform helps to disperse the pressure exerted by the hinge rod on the hinge, reduce local stress concentration, and extend the service life of the hinge. The support platform can be a part of the hinge, formed by a material bending or welding process, forming an upward extension part, namely the support platform, in the hinge area. During the installation process, the hinge rod is connected to the hinge of the hinge by a pivot, and the support platform provides an additional smaller contact surface and a more stable support, which contacts the corresponding part of the hinge rod. When the oven door is opened and closed, the noise that may be generated by the direct contact between the hinge rod and the hinge is reduced, ensuring that the oven is quiet and stable during use.

[0029] Further, as a preferred implementation manner of the present solution but not a limitation, the area of ​​the top of the support platform 12 is smaller than the area of ​​the bottom of the support platform 12 .

[0030] Furthermore, as a preferred implementation manner of the present solution but not a limitation, an arc-shaped transition is provided between the top of the support platform 12 and the bottom of the support platform 12 .

[0031] In this embodiment, the arc-shaped transition can reduce stress concentration, because stress concentration usually occurs at sharp corners or right angles, and the arc-shaped transition can smoothly disperse the force, thereby reducing the risk of material fatigue and fracture. Secondly, this design helps to reduce friction when the hinge rod contacts the support platform, because the arc-shaped transition provides a smooth contact surface and reduces the friction coefficient at the contact point, which helps to reduce wear and extend the service life of the hinge mechanism.

[0032] Furthermore, as a preferred implementation of the present solution but not a limitation, the hinge 1 includes a bending portion 13 and a supporting portion 14 , and a reinforcing rib 15 is provided at the connection between the bending portion 13 and the supporting portion 14 .

[0033] In this embodiment, the structural strength and rigidity of the connection area are significantly improved. This reinforcement can effectively withstand the repeated stress and load generated by the opening and closing of the door in daily use, reduce the bending and deformation of the hinge, and thus extend the service life of the hinge.

[0034] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the hinge 1 is arched upwards at a position corresponding to the support platform 12 to form the support platform 12 .

[0035] Further, as a preferred implementation manner of the present solution but not a limitation, the inner diameters of the first opening 11 and the second opening 21 are equal in length and smaller than the top area of ​​the support platform 12 .

[0036] In this embodiment, the inner diameter length of the two openings is smaller than the area of ​​the top of the support platform. This dimensional match can prevent the pivot from protruding or sinking excessively, ensure the positioning accuracy of the articulated rod on the support platform, and reduce noise and wear caused by pivot misalignment.

[0037] The working principle of this embodiment is as follows:

[0038] The hinge mechanism of the present application is a hinge mechanism that prevents abnormal noise. By improving the hinge mechanism of the oven, the connection method between the hinge rod and the hinged part is changed from the traditional double-sided bonding to single-sided contact, which effectively reduces the contact area between the two. When the door and the box body are opened and closed, the friction and wear degree can be reduced, thereby solving the problem in the prior art that after the oven has been used for a certain number of years, the door is prone to make abnormal noises when opening and closing relative to the box body. Therefore, the solution of the present application improves the use experience and durability of the oven and extends the service life of the product.

[0039] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or a number of technical deductions or replacements based on the concept of the present application, should be considered as the protection scope of this application.
