[Embodiment of the invention]

 Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view of an automatic barbecue cooking apparatus according to the present invention, in which a control panel unit 100 is installed on a front surface, and a number of natural-mixing surface-burning gas burners 200 are arranged side by side on an upper portion. .

FIG. 2 is a schematic configuration diagram for explaining in detail the natural-mixing type surface combustion gas burner 200 configured in FIG. As shown in FIG. 2, the gas burner 200 is composed of a naturally mixed venturi 201, a burner main body 202, a mixed gas dispersion plate 203, a mat support net 204, and a porous heat resistant metal fiber mat 205.

The porous heat-resistant metal fiber mat 205 is supported in an arch shape by a mat support net 204 and is attached to the burner main body 202. On the surface thereof, unlike an existing ceramic heating plate, a fine irregular shaped plate is formed. Pores are formed.

FIG. 3 is a configuration diagram of the surface combustion device. The ordinary city gas or the gas in the LPG container enters the gas control room 209 divided into two via the regulator 207 and the intermediate valve 208.

The gas control chamber 209 passes through a gas filter 210, a primary electronic valve 211, and a secondary electronic valve 212, and further passes through respective gas amount adjusting valves 213 and injection nozzles 214 while being divided by branch pipes. Then, it is connected to the naturally mixed Venturi tube 201.

A porous heat-resistant metal fiber mat 205 is attached to the upper stage of the burner body 202, and the combustible mixed gas that has passed through the naturally mixed venturi 201 is ejected through the fine pores of the porous heat-resistant metal fiber mat 205. Is done.

At this time, when ignition is performed by an igniter 206 installed on the surface of the mat, the porous heat-resistant metal fiber mat 205 is uniformly heated as a whole and emits infrared rays.

At this time, a mat support net 204 (see FIG. 2) is installed in an arc shape inside the burner main body 202 to prevent deformation of the porous heat-resistant metal fiber mat 205 by heating, and to disperse radiant heat. Can be done at the same time.

FIG. 4 is a schematic configuration diagram of the rotation device (revolution / rotation device) of the present invention. The rotation device of the present invention is provided with a first drive motor 301 as a rotation drive motor and a second drive motor 302 as a revolution / rotation motor. Here, the rotational force of the first drive motor 301 is transmitted to the rotation gear 19 through the transmission shaft 303 of the first drive motor 301, and the rotational force of the second drive motor 302 is transmitted to the transmission shaft 304 of the second drive motor 302. Is transmitted to the revolution / rotation gear 17.

FIG. 5 is a perspective view showing an operation relationship by the power transmission device of FIG. Here, the main improved component part is a combination of the sun gear 15 and the rotation gear 19 shown in a detailed sectional view at the upper right side of FIG. That is, the fastening pin 19A is installed between the sun gear 15 and the rotation gear 19 to be connected to each other.

FIG. 6 is a circuit diagram for automatically operating the rotating device of the present invention. The control circuit is configured and operated by a control panel unit 100 outside the device shown in FIG.

The operation of the present invention will be described with reference to FIGS. 5 and 6. First, in order to rotate the barbecue while heating the barbecue material, the switch (S / W1) in FIG. 6 is set to the "a" position, the first drive motor 301 operates and the transmission shaft 303 → rotation gear 1 9 → sun gear 15 → planetary gear 13 to rotate the barbecue material. That is, the rotation gear 19 also rotates the planetary gear 13 by the fastening pin 19A, and the six barbecue material fixing plates 27 (see FIG. 4) rotate.

When the general rotation and the barbecue material are to be rotated and revolved and rotated, the switch (S / W1) is set to the “b” position in FIG. When the transmission 302 is actuated, the transmission shaft 304 → the revolving / rotating gear 17 → the rotating shaft 9 → the rotating plate 7 is electrically driven so that the rotating plate 7 is rotated, so that the revolving is performed as a whole.

At this time, the barbecue material fixing plate 27 attached to the rotary plate 7 by the entire revolving operation rotates along with the revolving motion by the relative motion of the planetary gear 13 linked to the sun gear 15.

On the other hand, in the present invention, as shown in FIG. 5, in order to enable the rotation speed of the rotating device to be adjusted, the voltage is reduced by a 12V 24A AC through a 110V (or 220V) AC transformer, and then through a rectifier circuit. Converted to DC.

[0024] Furthermore, S / W3 can be used for filling, and can be used outdoors. In this case, when the changeover switch (S / W2) is positioned at the "d" position, the rotation speed of the rotating device can be increased by about twice from the "e" position.

Although the present specification has described the case where four gas burners 200 are installed, the number of gas burners 200 is not limited. Further, in the present invention, the gas burner 200 is set to be long in the horizontal direction, but it can be set to be short and many, and can be set to the left / right of the lower part.
