detailed description

The invention is further described below in conjunction with the drawings and embodiments.

Example 1

Referring to FIGS. 1-7, the embodiment includes an annular cooking chamber 1, a double-rotating grill 2, a transmission device 3 disposed between the bottom of the cooking chamber and the bottom plate 4 of the housing, and vertically disposed in the groove of the side wall of the cooking chamber 1. a plurality of barbecue tubes 5 and a drive motor 6, the grill 2 comprising a chassis 2.1, a column 2.2, an upper beam 2.3, a combined carrier 2.4, wherein the combined carrier comprises an annular upper cover 4.1, a drive gear 4.2 and a lower cover 4.3, A beam is arranged on the inner side of the inner wall of the annular upper cover 4.1, and a vertical axis 2.44 is arranged at the center of the beam, that is, at the center of the upper cover, and a card structure 2.44 formed by a hexagonal groove with an opening downward at the bottom of the vertical axis 2.44 is provided. c, the center of the chassis 2.1 is provided with a downwardly extending cylindrical structure for accommodating the bottom of the vertical axis 2.44, and a card boss is arranged around the circumference thereof, and a bottom portion of the vertical axis 2.44 is provided with a certain plasticity. Lubricate the bushing 2.44a, in order to prevent oil leakage, the vertical shaft 2.44, the self-lubricating bushing 2.44a and the chassis 2.1 are tightly fitted, and the transmission 3 includes a speed reduction through the transmission belt 3.3 and the output shaft of the drive motor 6. Wheel 3.1 and can be used with the bottom of the baking tray The fork of the .12 card position 3.2 further includes a positioning shaft 3.4 fixedly disposed on the bottom plate 4 of the casing. The fork 3.2 and the reduction wheel 3.1 are integrally designed and can be directly fitted on the positioning shaft 3.4 or can be set. On the lubrication bushing of the positioning shaft 3.4, The wear of the bottom surface of the reduction wheel 3.1 and the annular bearing surface of the positioning shaft 3.4 is reduced, and an annular lubrication pad is arranged between the two, and the top of the positioning shaft 3.4 is matched with the bottom bottom clamping structure 2.44c. a hexagonal card position boss, the center of the bottom of the cooking chamber 1 is provided with a circular hole matching the outer diameter of the fork 3.2, and the fork 3.2 passes through the circular hole and the card holder 2.12 at the bottom of the chassis 2.1. The top of the positioning shaft 3.4 passes through the reduction wheel 3.1 and the fork 3.2 to abut the card position 2.44c at the bottom of the upper cover vertical axis 2.44, and restricts the radial movement of the reduction wheel 3.1 and the fork 3.2. At the same time, the upper cover 2.43 is prevented from rotating with the grill. When grilling, the drive motor 6 drives the grill 2 and the combined carrier 2.4 rotated by the transmission belt 3.3, the reduction wheel 3.1 and the transmission of the fork 3.2. The upper cover 2.43 is held stationary by the stopping action of the positioning shaft 3.4 connected to the shaft, so that the driving gear 2.42 in the combined carrier 2.4 rotates around the inner wall of the upper cover 2.43 engaged with the bearing, thereby generating a rotation motion about its own axis, thereby realizing Hanging at the lower end of the drive gear 2.42 Food hung on the carrier member around the grill axis while revolving around its own axis of rotation. The stop of the upper cover 2.43 of the present embodiment is borne by the positioning shaft 3.4 attached to the bottom plate of the housing connected to the shaft, regardless of the shape and opening manner of the cooking chamber 1, and therefore, can be used for the cooking chamber of the shape used and various Open cooking device. Since the bottom of the vertical axis 2.44 and the grill chassis 2.1 are closely matched by the plastic self-lubricating bushing, the occurrence of oil leakage and pollution damage of the transmission device in the push-pull cooperation manner adopted in the prior art is avoided.

Example 2

Referring to FIG. 1 , FIG. 2 and FIG. 8 to FIG. 12 , the difference between the present embodiment and the first embodiment is mainly that the combined carrier upper cover 2.43 and the positioning shaft 3.4 are connected by a shaft provided on the grill chassis 2.1. The shaft connecting structure 2.11 is realized under the center, and the shaft connecting structure 2.11 is mainly provided with a rigid member which is respectively connected with the upper cover vertical axis 2.44 and the positioning shaft 3.4 with the card supporting structure 2.11b, 2.11c and the plasticity surrounding the outer side thereof. The lubricating bushing 2.11a is constructed, which has the advantage that the upper cover 2.43 and its vertical axis 2.44 can be removed, and the sealing effect is better and more durable. 2. The fork 3.2 and the reduction wheel 3.1 are of a split design, and the advantage is that the fork 3.2 can be disposed on the bottom plate of the cooking chamber 1, so that the through hole at the center of the bottom of the cooking chamber 1 can be greatly reduced. , reducing the chance that the retarder 3.1 and the belt 3.3 are damaged by oil contamination. Other parts not mentioned are the same as the first embodiment.

It should be noted that equivalent transformations made by the description of the present invention and the contents of the drawings, or different expressions of the same substantive meaning, and directly or indirectly applied in other related technical fields are within the scope of patent protection of the present invention. .
