Description

  The present invention accommodates a food to be cooked placed on a placement unit from an opening provided in front of the grille, and has a grille provided with a door that closes the opening, and is provided on a ceiling part of the grille. The present invention relates to a gas grill provided with an upper fire burner that heats the food to be cooked from above a placement section, and an exhaust passage that is connected to a rear portion of the grill cabinet and guides cooking exhaust to an upper exhaust outlet.

Such a gas grill heats a food to be cooked such as fish or pizza, and oil smoke may be generated when the food to be cooked is cooked. In particular, when cooking an object to be cooked with a large amount of oil and fat, such as sword fish, a large amount of oily smoke may be generated.
Generally, an exhaust duct directed upward is connected to the rear part of the grill cabinet, so that the combustion gas of the grill burner and the oil smoke generated when cooking the food to be cooked are discharged to the outside of the gas grill through the exhaust duct. The

  As a conventional example of such a gas grill, a catalyst filter for providing an afterburner for burning oil smoke passing through the exhaust duct at the bottom of the exhaust duct, and for smokeless and non-bromating the oil smoke at the middle of the exhaust duct (For example, refer to Patent Document 1).

According to Patent Document 1, even if oil smoke is generated in the grill, the amount of oil smoke discharged to the outside by the action of the afterburner burning the oil smoke and the action of the catalyst filter smokeless and non-bromating the oil smoke is reduced. It can be reduced.
Normally, in the case of a gas grill built in a gas stove, the combustion gas and oil smoke discharged to the outside from the exhaust duct are generally discharged from the gas grill, for example, by a ventilator installed in the kitchen. Combustion gas and oil smoke are discharged to the outdoors by a ventilation fan, so there is no major inconvenience even if some oil smoke is discharged from the gas grill when cooking the cooking object.

  However, when a large amount of oily smoke is discharged from the gas grill when cooking an oil-and-fat food such as sword fish, it is difficult to accurately discharge all of the discharged oily smoke outdoors with a ventilation fan. Then, although there is a possibility that the indoors may be polluted due to the oil smoke, Patent Document 1 can reduce the amount of oil smoke discharged to the outside of the gas grill.

  Incidentally, although there is no detailed explanation about the combustion control of the afterburner in this patent document 1, from the entire description in the column of the detailed explanation of the invention, when the combustion of the grill burner is started, the combustion of the afterburner Can be thought of as starting.
