Wherein: the device comprises a chassis 1, a stand column 2, an upper beam 3, a combined carrier 4, an upper cover, a driving gear and a lower cover of the combined carrier 4.1-4.3 in sequence, an upper wall, an inner wall, an outer wall, a braking structure and a tooth biting of the upper cover 4.11-4.15 in sequence, and a driving gear limiting groove, an annular bearing platform and a convex edge clamped with the upper beam of the lower cover 4.31-4.33 in sequence.

Detailed Description

The invention is further described below with reference to the figures and examples.

Example 1

Referring to fig. 1-3, the present embodiment includes a chassis 1, a pillar 2, an upper beam 3, a combined carrier 4, wherein the combined carrier includes an upper cover 4.1, a driving gear 4.2 and a lower cover 4.3, the upper cover 4.1 is an annular cover body, a rotating shaft of a structure abutting against a food carrier is extended downwards from the center of an original limiting circular truncated cone at the bottom of the driving gear 4.2, instead of and integrated with the functions of a stop rod and a central gear in the prior art, by a ruler-shaped stop structure 4.14 extended radially from the upper wall 4.11 and a tooth-biting tooth 4.15 arranged outside the inner wall 4.12, compared with the prior art, not only the food carrier tightly abutting against the driving gear and a nut for fastening are omitted, the thickness and the weight of the combined carrier are reduced, but also, a technical effect of allowing the driving gear to rotate bidirectionally can be obtained, the prior art allows the rotation in the nut tightening direction, rotation in a direction to withdraw the nut is not permitted. The lower cover 4.3 integrates the functions of the lower cover and the base in the prior art through a limiting circular groove 4.31 arranged at the bottom and a convex edge 4.33 extending at the edge of the bottom, and the base is omitted. When barbecuing, the lower cover 4.3 and the driving gear 4.2 of the combined carrier 4 rotate synchronously with the grill, the upper cover 4.1 of the combined carrier 4 is stopped due to the limit of the width of the cooking cavity by the stop structure, so that the upper cover 4.1 and the driving gear 4.2 which does circular motion relatively rotate, the biting teeth 4.15 at the outer side of the inner wall 4.12 thereof stir the teeth of the driving gear 4.2 which is meshed with the biting teeth, and the driving gear, the food carrier and the food which are connected with the driving gear rotate around the axis of the grill and simultaneously rotate around the axis of the grill, thereby realizing double-rotation baking. Because the annular combined carrier 4 is adopted, compared with the prior art adopting a disc-shaped combined carrier, the baking oven not only saves a plurality of elements and still keeps all original functions, but also lightens the weight, lowers the gravity center, improves the rotational stability of the baking rack, can observe the baking condition from the top, improves the heat exchange mode in the cooking cavity, and ensures that food is heated more uniformly and baked more efficiently.

Example 2

Referring to fig. 4-6, the difference between the embodiment and embodiment 1 is mainly 1. the driving gear 4.2 is reduced, and therefore, the driving gear 4.2 can be arranged more closely, so that the diameter of the inner ring of the annular combination carrier 4 is larger, the rotating speed of the driving gear 4.2 is higher, the observation is more convenient, and the baking effect is better. 2. The outer wall 4.13 of the upper cover 4.1 is removed, the support of the upper cover by the lower cover is changed from inner ring support to outer ring support, the lower cover 4.3 of the embodiment 1 is provided with an annular bearing platform 4.32 at the opening of the inner ring, the corresponding annular platform contacted with the inner wall 4.12 of the upper cover 4.1 is arranged, i.e. the inner wall 4.12 of the upper cover 4.1 in embodiment 1, takes over the tasks of limiting the shaft, loading and driving the drive gear 4.2, which makes the upper part of the inner wall 4.12, i.e. the lower part of the inner wall 4.12 in fig. 3, there is an annular weight bearing platform which is aligned with the annular weight bearing platform 4.32 in the lower cover 4.3, except for the teeth 4.15, so that the upper part of the inner wall 4.12 of the upper cover 4.1 is thicker and heavier, and at the same time, since the bottom surface of the outer wall 4.13 of the upper cover 4.1 must be abutted against the top surface of the outer wall of the lower cover 4.3 in order to allow the upper cover 4.1 to rotate smoothly, a supporting function is also provided in fact, but this causes a problem that frictional resistance between the upper and lower covers is increased. In this embodiment, the inner wall 4.12 of the upper cover 4.1 only bears the tasks of the limiting shaft and the driving gear 4.2, and the upper wall 4.11 of the upper cover 4.1 bears the load bearing task, so that the upper cover 4.1 is lighter in weight, simpler in structure, and smaller in rotation resistance, and meanwhile, the lower cover 4.3 is simpler in structure. The other parts not described are the same as those of the first embodiment.

It should be noted that all the equivalent transformation, or different expressions with the same essential meaning, which are directly or indirectly applied to other related technical fields, made by using the contents of the present specification and the attached drawings, are within the protection scope of the present invention.
