In addition, the cooking juices from the food to be cooked 2 generated by heating drip into the receiving colander 11 and collect therein.

Problems to be Solved by the Invention However, in the above configuration, if combustible materials are placed close to the rear surface of the device, the temperature of these materials will rise significantly due to the heat of the exhaust gas.

Furthermore, if the food to be cooked 2 is left to heat and cook for a long time, the water placed in the receiving colander 11 will evaporate, and the temperature of the accumulated grilled juices will rise, leading to smoking and ignition.

The combustion flame of the roasting juice is continuously discharged directly above from the slit hole 9a of the exhaust cover 9, and the combustion flame comes into contact with the combustible material on the rear surface of the appliance, abnormally raising the temperature of the combustible material, resulting in the danger of smoke and ignition. sexuality becomes greater.

In view of the above-mentioned problems, the present invention aims to eliminate exhaust gas generated by combustion,
To provide an exhaust device for a gas cooker that exhausts the combustion flame of grilled juice by tilting it toward the front of the appliance instead of directing it directly upward.

Means for Solving the Problems In order to solve the above problems, the exhaust device for a gas cooker of the present invention has an exhaust flue provided at the rear of the upper part of the baking chamber inclined toward the front side of the appliance, and The upper surface of the exhaust cover is provided with a slit hole on the front side of the device and a small hole on the rear side of the device.

Effect of the present invention With the above-described configuration, the exhaust gas generated by the combustion of the burner always flows toward the front side of the appliance along the slope of the exhaust flue, and the roasting liquid dripping from the food to be cooked is ignited. In this case, the combustion flame follows the slope of the exhaust flue and is discharged to the front of the appliance mainly through the slit hole in the exhaust cover, so the temperature of the combustible material at the rear of the appliance does not rise significantly.

EXAMPLE Hereinafter, an exhaust system for a gas cooker which is an example of the present invention will be described with reference to the drawings.
