Description

  The present invention relates to a stove including a grill storage.

  Conventionally, a stove with a grill for firing fish or the like is generally used. In this type of stove, a grill is arranged inside the grill, and cooking is performed by burning the grill burner in a state where an object to be cooked such as fish is placed on the grill. A saucer is provided below the grill net so as to receive oil dropped from fish or the like during cooking.

  By the way, the stove of most parts adopts a configuration that prevents ignition from oil accumulated in the saucer, such as cooling the saucer by circulating cooling air in the space below the saucer. It is desirable to provide some kind of flame extinguishing mechanism in preparation for actual ignition.

  As an example of the flame extinguishing mechanism, the present applicant has proposed a stove in which a frame trap is attached to the inside of the downstream downstream end of the exhaust pipe (see, for example, Patent Document 1). The frame trap is configured to include two or three or more perforated plates arranged substantially in parallel at a predetermined interval, and each of the perforated plates along the cylinder direction of the exhaust pipe in a state of being attached in the exhaust pipe. The plates are arranged sequentially. Each of the perforated plates is arranged so as to intersect the cylinder direction of the exhaust tube in a state of being attached in the exhaust tube, and so as not to form a gap between the inner side surfaces of the exhaust tube.

  In this stove, even if a flame is generated from the oil or the object to be cooked collected in the saucer, the flame is cooled in contact with the perforated plate located on the upstream side of the exhaust cylinder. Furthermore, since the carbon dioxide generated from the combustion exhaust gas and the food to be cooked is retained between the perforated plates, the oxygen concentration becomes lean, so that the oxygen supply to the flame is delayed. Such a cooling effect and an oxygen deficiency effect prevent the flame from overflowing outside the stove body beyond the flame trap.

  As a specific mechanism for mounting such a frame trap in the exhaust stack, a support member is provided on both the left and right ends of the frame trap so as to sandwich and support each porous plate. There has been proposed a mechanism for fixing the flange portion protruding to the flange portion protruding laterally from the upper end portion of the exhaust pipe (see, for example, Patent Document 2).
