Description

  The present invention relates to a grill and a method for heating an object to be cooked by the grill, and more particularly to a grill for heating and cooking an object to be cooked and a method for heating the object to be cooked by the grill.

  In a conventional grill, a double-sided grill is known in which a pair of burners are provided in the upper and lower stages of the grill cabinet. This double-sided grill can heat the front and back of the food to be cooked at a time as compared with a general grill in which only a pair of burners are provided in the grill cabinet. Therefore, it is not necessary to turn the front and back of the cooking object during heating, and both surfaces of the cooking object can be cooked in a short time at a time. And in such a conventional double-side grill grill, a grill net for placing fish and the like is horizontally disposed, and a pair of upper burners are provided on the upper side of the left and right inner surfaces. On the other hand, a pair of lower burners is provided on the lower stage of the left and right inner surfaces of the grill cabinet. In order to ignite each of the upper burner and the lower burner, a fire burner is disposed between the end of the upper burner and the end of the lower burner. And when this fire transfer burner is ignited, the upper burner and the lower burner are each ignited and both surfaces of the object to be cooked are heated.

In such a double-sided grill, for example, there is a grill burner fire transfer structure in which a fire burner whose fire foot is adjusted to be long can be ignited by the flame of the lower burner, and the flame after ignition reaches the upper burner. It has been proposed (see, for example, Patent Document 1). In this grill, by using a flame with a long fire foot for the grill burner, it is possible to easily perform a fire transfer, and it is possible to reduce the amount of gas required for the fire transfer.
