In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, so to speak, as communicating between the two elements. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art. The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1-3, the utility model discloses a machine core bearing shell, including roof 1 and first side plate 2 and second side plate 3 connected to roof 1 both sides respectively, the bottom inboard of first side plate 2 and second side plate 3 all is equipped with the mounting hole that is used for mounting the bottom plate, the inboard in the middle part of first side plate 2 is equipped with four first convex hulls 21 from top to bottom in proper order, and interval arrangement and formation three first supporting slot 22 between four first convex hulls 21; the middle part of the second side plate 3 is provided with a plurality of heat dissipation holes 31 arranged in an arc shape, the inner side of the middle part of the second side plate 3 is further provided with a plurality of second convex hulls 32, the second convex hulls 32 are separated from the heat dissipation holes 31, the plurality of second convex hulls 32 are arranged and arranged to form second support grooves 33 corresponding to the first support grooves 22, and the first support grooves 22 and the second support grooves 33 are used for supporting two sides of the grill. The utility model discloses convex closure on the board of usable both sides supports the multilayer gridion to have better supporting effect, save production material and cost, satisfy higher edible material heavy burden requirement. In the case of the movement of some household appliances, especially in the case of large-sized ovens, toasters, etc., the applicant has noticed that the inside of the existing case is provided with a large number of supporting mechanisms to erect the baking net and to achieve more accommodating spaces by layering, which theoretically facilitates the change of stress and the later replacement, but in practical use, people are usually less likely to detach screws, etc. to reinstall the components inside the toasters, such as the proper supporting slide rails, etc. Therefore, the utility model discloses a to the material aassessment of bearing shell, structure and production technology can directly be the convex closure that tensile height is not less than 8mm to the core shell, reduce the increase of extra annex like support screw, slide rail etc. reach reduce cost and promote production efficiency's purpose to can effectively bear the heavy burden of eating the material through the experiment. In addition, through the arrangement of forming the convex hulls on the side plates, the compression resistance and the tensile resistance of the panel can be effectively improved, and therefore, the corresponding convex hull design can be arranged on the top plate 1 according to actual use.

Further, the first and

second convex hulls

21, 32 have a protrusion height of at least 5.8mm, and the bottommost first convex hull 21 and the bottommost second convex hull 32 have a protrusion height of at least 7.8mm. As shown in fig. 1, the first convex hulls 21 and the second convex hulls 32 on the two side plates are divided into two parts, and are generally divided into four layers of convex hulls according to the specification and size, so as to form three layers of supporting grooves for being inserted into a grill and the like to perform a layered structure in the equipment, and the convex height of the upper three layers can be set to be 6mm, when the upper layer grill is used, the distance between the upper layer grill and the top plate 1 is limited, so that the weight of the food material is light, and the convex hulls can be relatively small.
