Description

Technical Field

[0001] This utility model relates to a microwave oven accessory, specifically an anti-detachment bracket for the oven turntable. Background Technology

[0002] Microwave ovens, as common cooking appliances in modern kitchens, rely heavily on their internal turntable system to ensure even heating of food. The turntable system typically consists of a turntable and a support frame, with the rollers on the frame being the key component for smooth turntable rotation. In current technology, microwave oven turntable supports are generally designed in a simple way: the rollers on the frame roll directly on the bottom of the microwave oven, which is usually finished with a paint coating to balance aesthetics and basic rust prevention. However, this design has revealed several significant drawbacks in practical use. These drawbacks not only affect the microwave oven's lifespan and performance but also negatively impact the user experience.

[0003] In existing microwave oven turntable designs, the stand typically consists of a connecting frame and several rollers. The rollers directly contact and roll on the painted surface of the microwave oven's bottom. This design is simple and inexpensive to manufacture, making it widely used in household microwave ovens. The bottom of the microwave oven is painted to improve its smoothness and aesthetics, and also to prevent oxidation and corrosion of the sheet metal to some extent. However, long-term use of this structure has revealed some problems that cannot be ignored.

[0004] Because the rollers roll directly on the painted surface of the microwave oven's bottom, the continuous friction and pressure between the rollers and the paint inevitably cause wear and tear. Over time, the paint will gradually peel off. Once the paint peels off, the underlying sheet metal will be directly exposed to the air, and especially in the humid environment inside the microwave oven, it is highly susceptible to rust. Rust not only damages the microwave oven's appearance but can also weaken the structural strength of the sheet metal, thus affecting the overall stability and safety of the microwave oven. For example, rusted sheet metal may experience localized corrosion, leading to structural fragility and, in extreme cases, even affecting the normal operation of the microwave oven.

[0005] During microwave oven use, food scraps, grease, and other debris can easily fall to the bottom and potentially enter the roller's rolling path. This debris can obstruct the roller's normal rotation, causing it to jam during rotation. Jammed rollers not only make the turntable's rotation uneven, affecting the evenness of food heating, but can also cause abnormal noise from the turntable system, significantly reducing the user experience. Furthermore, prolonged jamming can accelerate wear and tear on the rollers and support, further shortening the microwave oven's lifespan. Therefore, further improvements are necessary. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a turntable support for a microwave oven that is simple in structure, easy to use, can effectively prevent the rollers from directly abrading the paint on the bottom of the microwave oven, and reduces the impact of debris on the rollers' rolling, thereby improving the overall performance and service life of the microwave oven.

[0007] The purpose of this utility model is achieved through the following means: a stove turntable anti-detachment bracket, which includes a connecting frame, a plurality of wheel seats are evenly distributed on the connecting frame, and the upper end of the wheel seat is provided with a receiving cavity with an opening facing downward and recessed. An inner mounting groove is provided on the side wall of the receiving cavity near the center of the connecting frame, and an outer mounting groove is provided on the side wall away from the center of the connecting frame.

[0008] It also includes rollers, one end of which is provided with an inner limit shaft, and the other end of which is provided with an outer limit shaft;

[0009] The inner end face of the inner limiting shaft is provided with an inner wheel shaft, which is installed in the inner mounting groove;

[0010] The outer end face of the outer limiting shaft is provided with an outer wheel shaft, which is installed in the outer mounting groove;

[0011] An inverted seat extends obliquely downward from the upper opening of the accommodating cavity. After the roller is installed in the accommodating cavity, the inverted seat contacts the outer circle of the inner limiting shaft and the outer limiting shaft, limiting the radial displacement of the roller.

[0012] Furthermore, four inverted mounting seats are provided, symmetrically distributed on both sides of the inner mounting groove and the outer mounting groove.

[0013] Furthermore, the upper end of the inverted seat is inclined downwards and has a guide slope.

[0014] Furthermore, the bottom of the wheel seat extends downward to form a support base, which is distributed at both ends of the wheel seat and located near the connecting frame.

[0015] Furthermore: the bottom of the accommodating cavity is provided through the bottom of the wheel seat.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0017] 2. Due to the support base, the rollers do not contact the bottom of the microwave oven during movement. In contrast, in traditional designs, the rollers roll directly on the bottom of the microwave oven. In this invention, the rollers only rotate on the connecting frame, while the turntable rolls on the rollers. This design avoids direct contact and rolling between the rollers and the painted surface of the microwave oven bottom, thus eliminating wear on the paint. The paint remains intact, and the sheet metal material at the bottom is not exposed to a humid environment, effectively preventing rust and significantly extending the microwave oven's lifespan and enhancing its aesthetics.

[0018] 3. The rollers are installed within the housing cavity of the roller holder and secured by inner and outer mounting slots. This design surrounds the rollers within the roller holder, reducing the chance of food residue, grease, and other debris entering the roller path compared to traditional designs where the rollers are directly exposed at the bottom of the microwave oven. This further enhances the reliability of the turntable system.

[0019] 4. The design of the inverted seat and the limiting shaft makes it difficult for the roller to fall out, ensures good rolling effect, and allows it to maintain its original working condition even after long-term use. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A stove turntable anti-detachment bracket includes a connecting frame 1, on which a plurality of wheel seats 2 are evenly distributed. The upper end of each wheel seat 2 has a downward-facing recessed accommodating cavity 3. An inner mounting groove 4 is formed on the side wall of the accommodating cavity 3 near the center of the connecting frame 1, and an outer mounting groove 5 is formed on the side wall away from the center of the connecting frame 1.

[0026] It also includes a roller 6, one end of which is provided with an inner limit shaft 63, and the other end of which is provided with an outer limit shaft 64;

[0027] The inner end face of the inner limiting shaft 63 is provided with an inner wheel shaft 62, and the inner wheel shaft 62 is installed in the inner mounting groove 4;

[0028] The outer end face of the outer limiting shaft 64 is provided with an outer wheel shaft 61, and the outer wheel shaft 61 is installed in the outer mounting groove 5;

[0029] An inverted seat 7 extends obliquely downward from the upper opening of the accommodating cavity 3. After the roller 6 is installed in the accommodating cavity 3, the inverted seat 7 contacts the outer circle of the inner limiting shaft 63 and the outer limiting shaft 64, thereby limiting the radial displacement of the roller 6.

[0030] In one embodiment: four inverted mounting bases 7 are provided, symmetrically distributed on both sides of the inner mounting groove 4 and the outer mounting groove 5.

[0031] In one embodiment, the upper end of the inverted seat 7 is provided with a guide slope 71 that is inclined downwards.

[0032] In one embodiment: the bottom of the wheel seat 2 extends downward to form a support seat 8, which is distributed at both ends of the wheel seat 2 and is located near the connecting frame 1.

[0033] In one embodiment: the bottom of the accommodating cavity 3 extends through the bottom of the wheel seat 2.

[0034] Working Principle: In this case, the core structure of the microwave oven turntable support includes a connecting frame 1, wheel seats 2, a receiving cavity 3, an inner mounting groove 4, an outer mounting groove 5, and rollers 6. The connecting frame 1 serves as the main body of the support, with several wheel seats 2 evenly distributed on it. The upper opening of each wheel seat 2 is recessed downwards to form a receiving cavity 3, which is used to accommodate the rollers 6. An inner mounting groove 4 is formed on the side wall of the receiving cavity 3 near the center of the connecting frame 1, and an outer mounting groove 5 is formed on the side wall away from the center of the connecting frame 1. An outer axle 61 extends outwards from the outer end of the rollers 6. The inner axle 62 and the outer axle 61 are rotatably mounted in the inner mounting groove 4 and the outer mounting groove 5, respectively. After the rollers 6 are installed, their outer circular surface protrudes from the upper end surface of the wheel seat 2, directly supporting the bottom of the microwave oven turntable.

[0035] When the microwave oven turntable is placed on the support, the bottom of the turntable contacts the outer surface of the roller 6. As the turntable rotates under the drive of the motor, friction causes the roller 6 to rotate within the inner mounting groove 4 and outer mounting groove 5 of the accommodating cavity 3. The rotation of the roller 6 allows the turntable to rotate smoothly, ensuring that the food inside the microwave oven is heated evenly. Unlike traditional designs, in this invention, the roller 6 is mounted on the connecting frame 1, which remains stationary; only the roller 6 rotates on the connecting frame 1, while the turntable rolls on the roller 6.

[0036] In traditional designs, the rollers roll directly on the painted surface of the microwave oven's bottom, causing paint peeling and sheet metal rusting due to prolonged friction. In this invention, the rollers 6 do not directly contact the bottom of the microwave oven, avoiding rolling pressure on the painted surface and fundamentally eliminating the paint peeling problem, thus extending the microwave oven's lifespan.

[0037] In addition, in this case, the inner wheel axle 62 is provided with an inner limiting shaft 63 at one end near the roller 6, and the outer wheel axle 61 is provided with an outer limiting shaft 64 at one end near the roller 6. After the roller 6 is installed in the accommodating cavity 3, the inner limiting shaft 63 and the outer limiting shaft 64 are in contact with the two side walls of the accommodating cavity 3 to prevent the roller 6 from undergoing axial left and right displacement during rotation.

[0038] Additionally, a retaining seat 7 extends downwards at an angle from the upper opening of the accommodating cavity 3. After the roller 6 is installed, the retaining seat 7 is located outside the outer circle of the inner limiting shaft 63 and the outer limiting shaft 64. During normal use, the retaining seat 7 does not participate in the operation. After a period of use, when the axle wears down and falls outwards from the limiting position, the retaining seat, by limiting the inner limiting shaft 63 and the outer limiting shaft, restricts the radial vertical displacement of the roller 6, thus preventing it from falling off and extending the product's service life. Therefore, compared with traditional technology, in this case, through dual axial and radial limiting, the roller 6 will not deviate or jump during rotation, ensuring the smoothness and reliability of the turntable's rotation. This design effectively avoids the jamming problem caused by roller displacement in traditional brackets.

[0039] Furthermore, in this design, the reinforcing ribs extend downwards from the bottom of the wheel seat 2, distributed at both ends of the wheel seat 2 near and away from the center of the connecting frame, enhancing the support force of the wheel seat 2 and ensuring its stability when bearing the weight of the turntable. Simultaneously, they are located on the side of the support base 8 near the connecting frame 1, connecting the support base 8 and the connecting frame 1, improving the rigidity and stability of the overall structure. The design of the support base 8 and the reinforcing ribs 81 allows the bracket to withstand greater loads, extending the service life of the bracket, especially maintaining structural integrity under prolonged use or heavy loads.

[0040] In summary, in this case, the roller 6 is rotatably mounted within the wheel seat 2 of the connecting frame 1 via the inner wheel axle 62 and the outer wheel axle 61, supporting the turntable and enabling its smooth rotation. The connecting frame 1 remains stationary, preventing the roller from directly rolling on the bottom of the microwave oven, thus preventing paint peeling and sheet metal rusting. Simultaneously, the inner limit shaft 63, the outer limit shaft 64, and the inverted seat 7 ensure the axial and radial stability of the roller, while the support seat 8 and reinforcing rib 81 enhance structural strength. The shape design of the connecting frame ensures overall balance, thus allowing for widespread application.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
