DETAILED DESCRIPTION
[0018] A self-aligning turntable for a microwave oven of the present invention is realized as follows: A self-aligning turntable for a microwave oven of the present invention comprises a top turntable (1), anti-slip convex strips (2), transverse sliding grooves (3), transverse sliding strips (4), a bottom turntable (5), a middle turntable (6), vertical sliding strips (7), vertical sliding grooves (8), balls (9), a limit snap ring (10) and a hemispherical support block (11), wherein the limit snap ring (10) is arranged at the bottom of the bottom turntable (5) and at the center of the bottom turntable (5), the middle turntable (6) is arranged at the top of the bottom turntable (5), the top of the bottom turntable (5) is provided with a transverse sliding groove (3), the bottom of the middle turntable (6) is provided with a transverse sliding strip (4), and the transverse sliding strip (4) is slidably arranged in the transverse sliding groove (3), The top turntable (1) is placed on the top of the middle turntable (6), the top of the middle turntable (6) is provided with a vertical slide groove (8), the vertical slide groove (8) and the horizontal slide bar (4) are perpendicular to each other, the bottom of the top turntable (1) is provided with a vertical slide bar (7), the vertical slide bar (7) is slidably placed in the vertical slide groove (8), the top of the middle turntable (6) is provided with a hemispherical support block (11), the top of the bottom turntable (5) is provided with a hemispherical support block (11), the hemispherical support blocks (11) are arranged in a ring matrix, the vertical slide groove (8) is provided with a built-in ball (9), the horizontal slide groove (3) is provided with a built-in ball (9), the ball (9) is arranged in a matrix, and the top of the top turntable (1) is provided with a plurality of anti-slip convex strips (2).
[0019] When in use, the prime minister engages the bottom turntable (5) and the middle turntable (6) through the horizontal groove (3) and the horizontal slide bar (4), engages the middle turntable (6) and the top turntable (1) through the vertical groove (8) and the vertical slide bar (7), and then places the bottom turntable (5) on the motor shaft of the rotating motor at the bottom of the microwave oven through the limit clamp ring (10), and places the container containing food on the top turntable (1). When the microwave oven rotates for heating, the motor shaft of the rotating motor drives the bottom turntable (5), the middle turntable (6) and the top turntable (1) to rotate to heat the food. When the food container and the inner wall of the microwave oven are stuck, the inner wall of the microwave oven exerts a reaction force on the food container. When the reaction is in the direction of the vertical slide bar (7), the reaction force pushes the vertical slide bar (7) in the vertical groove ( 8) slides in the middle, causing the top turntable (1) and the middle turntable (6) to deviate, thereby causing the food container to be away from the inner wall of the microwave oven. When the reaction force is in the direction of the horizontal slide bar (4), the reaction force pushes the horizontal slide bar (4) to slide in the horizontal and vertical grooves, causing the middle turntable (6) and the bottom turntable (5) to deviate, thereby causing the food container to be away from the inner wall of the microwave oven and rotate. When the food container contacts and gets stuck with the inner wall of the microwave oven, the position of the food container can be automatically adjusted, so that the food container rotates smoothly, thereby ensuring the normal service life of the rotating motor. When the heating is finished, the staff can use the anti-slip convex strip (2) to appropriately pull the top turntable (1) out a certain distance, thereby exposing the food container to the microwave oven, making it more convenient for the staff to take it out;
[0020] The design of the anti-slip convex strip (2) can, on the one hand, increase the friction between the food container and the top turntable (1), so that when the reaction force pushes the food container, the top turntable (1) can be moved together with the food container; on the other hand, when the food is heated, the staff can pull out the top turntable (1) through the protective convex strip, and the vertical slide bar (7) is engaged in the vertical slide groove (8) to support the top turntable (1), so that it is convenient for the staff to take the food container without having to put their hands into the microwave oven to cause burns;
[0021] The vertical slide groove (8) and the horizontal slide bar (4) are designed to be perpendicular to each other, so that the vertical slide bar (7) and the horizontal slide bar (4) can form a cross shape corresponding to each other, which can adapt to various situations where the food container is stuck. When the food container is stuck, the reaction force of the inner wall of the microwave oven on the food container can always be decomposed into a cross state, so that the vertical slide bar (7) and the horizontal slide bar (4) can slide;
[0022] The top of the middle turntable (6) is provided with a hemispherical support block (11), and the top of the bottom turntable (5) is provided with a hemispherical support block (11). The hemispherical support block (11) can change the surface contact into point contact through the hemispherical support block (11), thereby reducing the friction between the middle turntable (6) and the bottom turntable (5) and the friction between the middle turntable (6) and the top turntable (1), so that the sliding between the top turntable (1) and the middle turntable (6) and the middle turntable (6) and the top turntable (1) is smoother;
[0023] The design of the hemispherical support blocks (11) being arranged and distributed in a ring matrix enables the hemispherical support blocks (11) to be evenly distributed, so that when the top turntable (1) slides on the middle turntable (6), and the middle turntable (6) slides on the bottom turntable (5), the friction force can be decomposed and transmitted through the evenly distributed hemispherical support blocks (11), making the sliding smoother and avoiding the deviation and jamming during the sliding process due to too few hemispherical support blocks (11);
[0024] The design of the vertical slide groove (8) having a built-in ball (9) and the horizontal slide groove (3) having a built-in ball (9) can change the surface contact into point contact, thereby reducing the friction force, making the vertical slide bar (7) and the horizontal slide bar (4) slide more smoothly, and avoiding jamming caused by excessive friction force;
[0025] The design of the matrix arrangement and distribution of the balls (9) can make the vertical slide bar (7) and the horizontal slide bar (4) evenly stressed, and transmit the reaction force received by the upper part through the evenly distributed balls (9), so that the balls (9) decompose the reaction force, making the vertical slide bar (7) and the horizontal slide bar (4) slide more smoothly;
[0026] The design of the cross-sliding bar (4) and the cross-sliding groove (3) in coordination enables, when the reaction force is in the direction of the cross-sliding bar (4), the cross-sliding bar (4) slides in the cross-sliding groove (3) through the reaction force, thereby causing the middle turntable (6) and the bottom turntable (5) to deviate, thereby adjusting the position of the food container and allowing the food container to continue to rotate;
[0027] The design of the vertical slide bar (7) and the vertical slide groove (8) being matched together enables, when the reaction force is in the direction of the vertical slide bar (7), the reaction force pushes the vertical slide bar (7) to slide in the vertical slide groove (8), causing the top turntable (1) and the middle turntable (6) to deviate, thereby allowing the food container to move away from the inner wall of the microwave oven and continue to rotate;
[0028] The bottom turntable (5) and the middle turntable (6) are engaged with each other through the horizontal slide groove (3) and the horizontal slide bar (4), the middle turntable (6) and the top turntable (1) are engaged with each other through the vertical slide groove (8) and the vertical slide bar (7), and the bottom turntable (5) is placed on the motor shaft of the rotating motor at the bottom of the microwave oven through the limit clamp ring (10), so that the microwave oven can be started, and the motor shaft of the rotating motor in the microwave oven drives the bottom turntable (5) to rotate. Since the horizontal slide groove (3) and the horizontal slide bar (4) are engaged, and the vertical slide groove (8) and the vertical slide bar (7) are engaged, the bottom turntable (5), the middle turntable (6) and the top turntable (1) form a linkage relationship. When the bottom turntable (5) rotates, the middle turntable (6) and the top turntable (1) rotate accordingly, so that the food container is heated by rotation.
[0029] The purpose is to automatically adjust the overall center of gravity when the food container and the inner wall of the microwave oven come into contact and become stuck, so that the food container can rotate smoothly, while ensuring the normal service life of the microwave oven's rotating motor.
