Description

[Technical field]

[0001] The present application belongs to the technical field of household appliances, and in particular relates to a limiting mechanism for a rotating fork of an oven. [Background technology]

[0002] An oven is a sealed appliance used to bake food or dry products. It is divided into household ovens and industrial ovens. The interior of the oven is a drawer-type structure used to store the ingredients to be baked. After the ingredients are placed on a tray in the oven, they are heated and baked using circulating hot air. In this heating method, since the angle of the ingredients cannot be changed, in order to evenly heat all parts of the ingredients, the food needs to be inserted into the fork. Driven by the motor, the fork rotates so that all parts of the ingredients are evenly heated. Since the convenience of disassembly and assembly of the fork needs to be considered, an opening needs to be provided on the part that receives the fork for easy removal and installation. However, when heating large-mass ingredients, the baking ovens currently on the market are easily affected by friction, which can cause the fork to detach along the opening when it rotates. [Utility Model Content]

[0022] 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.

[0023] See also Figures 1 to 6 A limiting mechanism for an oven swivel fork comprises a swivel fork 1 having one end connected to an output end of a motor, and a limiting member 2 for supporting the other end of the swivel fork 1, wherein the limiting member 2 is provided with a supporting groove 21 extending downward from the top of the limiting member 2 and for supporting the swivel fork 1, and an opening length of the supporting groove 21 is less than an inner diameter length of the supporting groove 21.

[0024] The limiting mechanism of the oven swivel fork of the present application enables the swivel fork to bear and bake heavier food materials by arranging a supporting groove on the limiting member, and forms a barrier to limit the upward movement of the swivel fork through a structural setting in which the opening length is smaller than the inner diameter length, thereby limiting the swivel fork from automatically separating from the supporting groove when rotating, thereby enhancing the safety of use, avoiding potential safety hazards, and improving the performance and reliability of the oven.

[0025] Furthermore, as a preferred implementation manner of the present solution but not a limitation, both sides of the opening of the supporting groove 21 are first arc edges 211 that are mirror images of each other, and the bottom of the supporting groove 21 is a second arc edge 212 that is tangent to the first arc edge 211 .

[0026] In this embodiment, by setting two first arc edges that are mirror images of each other on both sides of the opening of the supporting groove, and making the bottom of the supporting groove tangent to the second arc edge, the swivel fork can be stably supported and limited. Since the opening length is less than the inner diameter length, the swivel fork will not be separated due to excessive friction during the rotation process. Such a design not only ensures the stable operation of the swivel fork when the oven is working, so that the food is heated more evenly, but also enhances the reliability of the mechanism and avoids the safety hazards caused by the accidental separation of the swivel fork. The supporting groove can be designed as an arc groove with other curvatures and shapes, and the first arc edges on both sides of the opening are symmetrically arranged in a mirrored manner, and the second arc edge at the bottom is tangent to the first arc edge to form a complete arc inner cavity. When the swivel fork is inserted into the supporting groove, its outer diameter matches the inner diameter of the supporting groove, and the swivel fork tends to move upward under the action of friction when rotating, but under the joint action of the first arc edge and the second arc edge, the friction force is reduced and the upward movement is stopped, so that the swivel fork remains stable during rotation and its upward separation is limited. This structure is simple and easy to manufacture, and can effectively solve the problem of the rotating fork being detached during the use of the oven, thereby improving the overall performance of the oven and the user experience.

[0027] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the supporting groove 21 includes a limiting section 213 for limiting the swivel fork 1 from upwardly disengaging from the supporting groove 21 when rotating, and a receiving section 214 for receiving and allowing the swivel fork 1 to rotate in the supporting groove 21.

[0028] Further, as a preferred implementation of the present solution but not a limitation, the inner diameter length of the limiting section 213 is L, the inner diameter length of the receiving section 214 is S, and the diameter of the swivel fork 1 is R, wherein S>L>R.

[0029] In this embodiment, by setting the inner diameter length L of the limiting section to be larger than the diameter L of the swivel fork, the swivel fork can rotate smoothly in the supporting groove. The inner diameter length L of the limiting section is smaller than the inner diameter length S of the receiving section, so that when the swivel fork rotates, it is prevented from detaching upward due to centrifugal force.

[0030] Furthermore, as a preferred implementation of the present solution but not a limitation, the limiting member 2 is U-shaped, including connecting portions 22 located on both sides, and a mounting portion 23 located in the middle, and the mounting portion 23 protrudes upward relative to the connecting portion 22 to form a clearance space 24.

[0031] In this embodiment, by providing an upwardly protruding mounting portion in the middle of the limit member and forming a clearance space with the connecting portions on both sides, a stable supporting structure can be provided, and a clearance space can be provided for the first limit block on the swivel fork, ensuring that the swivel fork will not deviate laterally during rotation.

[0032] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the swivel fork 1 is connected to the motor output end via a rotating seat 3, the rotating seat 3 includes a connecting seat 31 and a connecting sleeve 32, a hole is provided on the connecting seat 31, the motor output end passes through the hole and is rotatably connected to the connecting sleeve 32, and one end of the swivel fork 1 is inserted into the connecting sleeve 32.

[0033] In this embodiment, the connection method of the rotating seat enables flexible rotation between the rotating fork and the motor output end, thereby accurately transmitting the rotational motion of the motor to the rotating fork, so that the food can be evenly heated. Secondly, the hole design on the connecting seat allows the motor output end to pass through the hole and be rotatably connected to the connecting sleeve. This structure not only ensures the firmness of the connection, but also allows the rotating fork to be easily disassembled or replaced when necessary. In addition, one end of the rotating fork is inserted into the connecting sleeve, which can achieve seamless docking between the rotating fork and the motor output end, reduce energy loss during transmission, and improve the working efficiency of the oven.

[0034] Furthermore, as a preferred implementation mode of the present invention but not a limitation, both ends of the swivel fork 1 are provided with a first limit block 11 and a second limit block 12, the first limit block 11 and the second limit block 12 are spaced apart, and the supporting groove 21 is inserted between the first limit block 11 and the second limit block 12.

[0035] In this embodiment, the spacing between the first limit block and the second limit block can improve the stability and reliability of the connection and prevent the swivel fork from loosening or falling off during the rotation process. Secondly, this limit structure can effectively guide and constrain the movement of the swivel fork, making its movement in the supporting groove more stable and controllable, thereby reducing the generation of vibration and noise.

[0036] Further, as a preferred implementation manner of the present solution but not a limitation, the spacing distance between the mounting portion 23 and the connecting portion 22 is H, and the spacing distance between the first limiting block 11 and the second limiting block 12 is D, wherein D<H.

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

[0038] The limiting mechanism of the oven swivel fork of the present application enables the swivel fork to bear and bake heavier food materials by arranging a supporting groove on the limiting member, and forms a barrier to limit the upward movement of the swivel fork through a structural setting in which the opening length is smaller than the inner diameter length, thereby limiting the swivel fork from automatically separating from the supporting groove when rotating, thereby enhancing the safety of use, avoiding potential safety hazards, and improving the performance and reliability of the oven.

[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 some technical deductions or replacements made based on the concept of the present application, shall be deemed to be within the protection scope of this application.
