TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, specifically, a rotating support and a microwave oven. BACKGROUND

[0002] The microwave oven has become one of indispensable cooking appliances in modern families by using the heat generated by the high-speed movement and friction of water molecules to rapidly heat food.

[0003] In order to make the food evenly heated, a motor is generally arranged at the bottom of the microwave oven cavity for driving the glass turntable to rotate; in order to ensure that the circular glass plate is placed stably in the cavity, a support structure such as a Y-shaped or O-shaped rotating support is usually arranged to assist, and a circular roller is arranged on the rotating support to realize the stable rotation of the glass plate. For example, the prior application with the application number 201922182925.3 discloses a rotating support including a support body, a plurality of fixed shafts are arranged on the support body, a connecting strip is formed between adjacent two fixed shafts, at least one connecting strip is provided with a buffer part, and the buffer part includes an outer buffer surface and / or an inner buffer. This scheme can effectively prevent the rotating support from breaking or being damaged, and the roller will continuously wear the metal surface when rolling in the cavity, which will cause rust on the bottom of the cavity and seriously affect the customer experience.

[0004] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

[0005] The problem solved by the utility model is that when the roller in the commonly used O-shaped rotating support assembly rolls on the surface of the cavity bottom, it will continuously rub the sprayed surface of the cavity bottom and cause the peeling of the sprayed layer and even rust and other abnormal problems on the cavity bottom.

[0006] To solve the above problems, the utility model provides a rotating support for a microwave oven, wherein the microwave oven includes a cavity, a glass turntable is arranged in the cavity for placing food; the rotating support includes a support and a ball, a mounting seat is arranged on the support for limiting assembly of the ball, the ball can freely rotate and partially protrude from the mounting seat for abutting against the glass turntable.

[0007] This arrangement can ensure that the highest point of the ball abuts against the glass turntable, and the ball itself does not contact the lower bottom surface of the cavity, thereby effectively avoiding the friction of the ball against the cavity bottom and even the peeling of the sprayed layer; the ball can further reduce the rotation resistance of the glass turntable and reduce energy consumption.

[0008] Preferably, the mounting base comprises a hollow sleeve for accommodating and horizontally limiting the ball; the upper end of the sleeve is provided with a limiting structure for vertically limiting the ball, and the ball is partially higher than the limiting structure and the sleeve. This arrangement can accommodate the ball with the sleeve and prevent the ball from falling out with the limiting structure; the structure is simple, stable and reliable.

[0009] Preferably, a notch groove is provided on the sleeve and extends along the height direction of the sleeve, and the limiting structure is located adjacent to the notch groove on the inner wall of the sleeve. This arrangement saves raw materials while providing a certain deformation space for the sleeve, so that the ball passes through the limiting structure and enters the sleeve; the assembly of the ball does not require screws or other components, and the assembly efficiency is high.

[0010] Preferably, the notch groove has a plurality of first side walls and second side walls formed on both sides of the notch groove, the first side walls and the second side walls are spaced apart from each other, and the limiting structure has at least two limiting structures located at the upper end of the oppositely arranged first side walls or second side walls.

This arrangement can improve the overall mechanical strength of the mounting seat, and increase the contact points between the rotating support and the glass turntable to disperse the stress, so that the rotation of the glass turntable is more stable and reliable.
