Embodiment 1

[0014] see Figure 1-Figure 5 , this embodiment includes an annular cooking chamber 1, a double rotating grill 2, a drive motor 3, and an electric control device 4. The grill 2 includes a chassis 2.1, a column 2.2, an upper beam 2.3, and a combined carrier 2.4, wherein the combined carrier The tool includes an annular upper cover 2.41, a drive gear 2.42 and a lower cover 2.43. The outer side of the inner wall 2.412 of the annular upper cover 2.41 is provided with teeth that engage with the above-mentioned drive gear 2.42, and are used for rotating the drive gear 2.42 with the grill 2. When making it rotate around its own axis, the inner side of the inner wall 2.412 of the annular upper cover 2.41 is provided with a counterweight beam 2.413, and a drooping counterweight 2.414 is provided at the center of the beam for increasing the upper cover When grilling, the electric control device 4 changes the running speed of the drive motor 3 in good time, so that the grill 2 can get ri...

Embodiment 2

[0016] Compared with Embodiment 1, the difference between this embodiment and Embodiment 1 is that R1 in Embodiment 1 is replaced by a non-contact Hall current sensor HS1. The function of R1 is to convert the load current into a voltage signal that is convenient for sampling. It is a dilemma. The small resistance value sampling voltage dynamic range is too small, and the large resistance value is not conducive to voltage stabilization and speed reduction, and is not conducive to reducing energy consumption. The Hall current sensor HS1 is composed of the power line of the drive motor 3 and the induction The coil is formed by co-winding a magnetic core, and the sampling signal is an induced current. Using it instead of R1 has the advantages of a wide dynamic range of the sampling signal and no power consumption. All the rest are the same as in Example 1.

Abstract

The invention discloses a method for preventing following rotation, and relates to a rotary barbecue grill, a driving motor for driving the rotary barbecue grill and an electric control device. The rotary barbecue grill comprises a combined carrier which is composed of an annular upper cover, an annular lower cover and driving gears; the annular upper cover can rotate relative to the annular lowercover and the driving gears, and the outer side of the inner wall of the annular upper cover is provided with meshing teeth meshed with the driving gears. The electric control device comprises a motor control circuit, the motor control circuit comprises a speed stabilizing and speed regulating circuit, and the speed regulating circuit is set with two switchable control voltages corresponding twostabilized output voltages of the driving motor; by alternatively switching the two control voltages, alternate conversion of the rotating speed of the driving motor is achieved, and the alternative switching is conducted when the load current change of the driving motor is smaller than a certain set value or when a voltage change related to the load current change of the driving motor is smallerthan a certain set value. Compared with the prior art, the rotary barbecue grill, the driving motor and the electric control device have the advantages that the service life of an existing motor is prolonged, the power consumption and cost are reduced, energy is saved, and the applicability of the dual-rotary barbecue technology and the barbecue uniformity are improved.

Description
