[0027] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0028] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0030] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0032] This application provides a cooking device. Please refer to... Figure 1 The cooking device includes a housing assembly 10, which has a cooking cavity 10a for containing food to be cooked. The form of the cooking device is not limited; it can be a microwave oven, a steam oven, or an oven, etc. This application specification uses a microwave oven as an example for illustration.

[0033] For example, the housing assembly 10 has an opening that communicates with the cooking cavity 10a. The cooking device includes a door assembly that is rotatably connected to the housing assembly 10 for opening and closing the opening, through which a user can take food into the cooking cavity 10a.

[0034] For example, in an embodiment where the cooking device is a microwave oven, the cooking device includes a magnetron and a waveguide. The magnetron emits microwave energy into the cooking cavity 10a through the waveguide, causing water molecules in the food to vibrate, thereby generating heat to cook the food. In an embodiment where the cooking device is an oven, the cooking device includes a light wave tube, which heats and cooks the food by generating thermal radiation into the cooking cavity 10a.

[0035] Uneven heating may occur when food is cooked inside the cooking cavity. Therefore, the cooking device provided in this application includes a turntable 21, a rotating shaft 22, and a motor 23. Please refer to... Figure 2 The turntable 21 is located in the cooking cavity 10a and is used to hold the food to be cooked. The rotating shaft 22 is connected to the motor 23, which drives the turntable 21 to rotate via the shaft 22, causing the food to rotate and ensuring that the food is heated evenly from all directions, resulting in better cooking. For example, the motor 23 can make the turntable 21 rotate at a uniform speed and continuously, which is simple and labor-saving.

[0036] Please see Figure 2 The housing assembly 10 includes a bottom wall portion 11, which, exemplarily, is located at the bottom of the cooking cavity 10a. The cooking device includes at least two support structures 30, i.e., the number of support structures 30 can be two, three, or more. The support structures 30 are connected to the bottom wall portion 11 and protrude from the top surface of the bottom wall portion 11. The turntable 21 is detachably placed on the top side of the rotating shaft 22 and the at least two support structures 30. It is understood that when the turntable 21 rotates, the bottom side of the turntable 21 slides in contact with the top side of the support structure 30, and the support structure 30 provides an upward supporting force to the turntable 21, which can reduce the probability of the turntable 21 tilting due to uneven weight distribution of the food to be cooked, and ensure the smooth movement of the turntable 21.

[0037] For example, the support structure 30 can provide a support point or a support surface for the turntable 21. The top side of the multiple support structures 30 will not completely cover the bottom side of the turntable 21, thereby reducing the dimensional accuracy requirements of the multiple support structures 30 protruding from the top surface of the bottom wall portion 11.

[0038] It is understood that the turntable 21 is pressed against the top side of the support structure 30, and the turntable 21 can be removed from the rotating shaft 22 and the support structure 30, so that users can use the cooking equipment flexibly and clean the turntable 21.

[0039] In this embodiment, the support structure 30 is connected to the bottom wall 11. The connection is simple and the support structure 30 is not easy to fall off or be lost. While multiple support structures 30 provide support for the turntable 21, they occupy less installation space and have a simple structure, which helps to reduce the production and manufacturing cost of cooking equipment.

[0040] It should be noted that in some embodiments of this application, the bottom side of the bottom wall portion 11 can directly form the bottom surface of the cooking device, while in other embodiments, the bottom side of the bottom wall portion 11 can be provided with other components for forming the bottom surface of the cooking device, and the bottom side of the bottom wall portion 11 is not directly exposed to the external environment.

[0041] In some embodiments, please refer to Figure 1 At least two support structures 30 are distributed on the same circle, and the circle is concentric with the pivot 22. It can be understood that in an embodiment with three support structures 30, the positions of the three support structures 30 define a circle, and in an embodiment with four or more support structures 30, all support structures 30 are located on the same circle.

[0042] In this embodiment, the distance from each support structure 30 to the rotating shaft 22 is the same, and the support effect on the turntable 21 is more uniform, which improves its motion stability.

[0043] For example, at least two support structures 30 are evenly spaced. It can be understood that in an embodiment with three support structures 30, the central angle corresponding to the positions of two adjacent support structures 30 is approximately 120°, and in an embodiment with N (N>3) support structures 30, the central angle corresponding to the positions of two adjacent support structures 30 is approximately 360° / N. In this way, the supporting force on the turntable 21 achieves force balance, further improving the stability of the turntable 21's movement.

[0044] In some embodiments, please refer to Figure 4The support structure 30 includes a spherical surface, through which it contacts the turntable 21. It should be noted that the spherical surface does not necessarily mean that the support structure 30 has a complete sphere; it only requires that the portion in contact with the turntable 21 is spherical. The spherical surface ensures a smooth transition in all directions during the sliding contact between the support structure 30 and the turntable 21, reducing jamming of the turntable 21 and wear on the support structure 30.

[0045] Of course, in other embodiments, the support structure 30 may also include other convex surfaces, such as ellipsoids, parabolic surfaces, etc.

[0046] For example, the support structure 30 is a one-piece structure. The one-piece support structure 30 has good structural strength, and its structure is simple and easy to manufacture.

[0047] For example, the material of the support structure 30 is not limited. For instance, in some embodiments, the support structure 30 is a polytetrafluoroethylene (PTFE) component, that is, the support structure 30 is made of polytetrafluoroethylene. Polytetrafluoroethylene has the characteristics of high temperature resistance and extremely low coefficient of friction, so it can have a lubricating effect and is suitable for use in oil-free lubrication scenarios such as microwave ovens.

[0048] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The support structure 30 includes a hemispherical portion 31 and a mounting portion 32. The top side of the hemispherical portion 31 forms a spherical surface, and the mounting portion 32 is connected to the bottom side of the hemispherical portion 31 and is disposed on the bottom wall portion 11. It should be noted that the hemispherical portion 31 is not necessarily half of a complete sphere, but should be understood as a geometric structure formed by rotating an arc about the perpendicular bisector of the line connecting its two endpoints.

[0049] In this embodiment, the top side of the hemispherical portion 31 can be formed into a spherical surface, and the bottom side of the hemispherical portion 31 can be used for support and stop, and is fixed to the bottom wall portion 11 by the mounting portion 32. In this embodiment, the support structure 30 is simple and easy to install.

[0050] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The bottom wall portion 11 has at least two through holes 11a, and the mounting portion 32 passes through the through holes 11a and is interference-fitted with the through holes 11a. That is, the outer edge shape of the mounting portion 32 matches the shape of the through hole 11a, and the outer edge dimension of the mounting portion 32 is not smaller than the dimension of the through hole 11a, so that the mounting portion 32 is stably embedded in the through hole 11a. This connection method is convenient to install, and only the mounting portion 32 needs to be pressed into the through hole 11a, without the need for additional fasteners, thus saving costs.

[0051] For example, the mounting portion 32 is cylindrical, such as Figure 1 As shown in the image.

[0052] For example, the inner diameter of the through hole 11a is 4.0 mm and the outer diameter of the mounting post is 4.1 mm.

[0053] In some embodiments, please refer to... Figure 1 , Figure 3 and Figure 4 A portion of the bottom wall 11 is folded downward to form a flange 111, which is connected to the edge of the through hole 11a. The mounting part 32 is interference-fitted with the flange 111. It can be understood that the outer edge dimension of the mounting part 32 is not smaller than the inner surface dimension of the flange 111, so that the mounting part 32 is stably embedded in the flange 111 and is not easy to wobble.

[0054] For example, the flange 111 is formed by a stamping process. Specifically, during the manufacturing process, the position of the through hole 11a is initially machined on the workpiece forming the bottom wall portion 11. The through hole 11a and the flange 111 are processed by stamping with a mold. In this way, the flange 111 and the bottom wall portion 11 are an integral structure with a simple structure. The flange 111 also has a certain degree of extensibility, which facilitates the installation of the support structure 30.

[0055] In some embodiments, please refer to Figure 4 The end of the mounting part 32 away from the hemispherical part 31 has a chamfered structure. The chamfered structure refers to the bevel or rounded corner structure formed by machining the edge of the end of the mounting part 32 away from the hemispherical part 31. In this way, not only can burrs be removed, but the end of the mounting part 32 away from the hemispherical part 31 also has a guiding function, which makes it easy to smoothly insert the mounting part 32 into the through hole 11a.

[0056] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 7 The outer periphery of the rotating shaft 22 has a stepped surface, meaning that a portion of the rotating shaft 22 protrudes radially outward, forming a stepped surface that is offset from other parts. The bottom wall portion 11 has an upwardly protruding boss 112, and the stepped surface is supported on the top surface of the boss 112, which provides support force to the stepped surface. In this embodiment, while the rotating shaft 22 drives the turntable 21 to rotate, it can distribute the load it bears to the boss 112, thereby achieving a supporting effect on the turntable 21, reducing the pressure on the supporting structure 30, and reducing frictional loss.

[0057] In some embodiments, please refer to Figure 1The cooking device includes a mounting base 40 and a connector (not shown). The mounting base 40 is disposed on the bottom side of the bottom wall portion 11, and the motor 23 is disposed on the bottom side of the mounting base 40. The connector connects the motor 23 and the mounting base 40. The mounting base 40 provides support for the installation of the motor 23.

[0058] For example, the motor 23 includes a housing and a power output shaft, the power extension shaft extends out of the housing and is connected to the rotating shaft 22, and the mounting base 40 is disposed between the bottom wall portion 11 and the housing, which facilitates the stable fixing of the housing of the motor 23 to the bottom wall portion 11.

[0059] For example, the mounting base 40 is mounted to the bottom wall portion 11 by fasteners, including but not limited to screws or rivets; or, in other embodiments, the mounting base 40 is welded to the bottom wall portion 11.

[0060] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
