Description

  The present invention relates to a grill provided on a table stove or the like for heating an object to be cooked such as fish.

  The grill provided on the table stove or the like has a burner at the top of the grill cabinet, and the infrared cooking heat from the burner is placed on the cooking unit placed on the grill net or other placement section. Cook with heat. In this type of grill, a grill having a pair of left and right burners extending in the depth direction is known (see Patent Document 1). In this type of burner, a flat combustion surface is formed by a horizontally long ceramic plate in which many small flame holes are formed, and radiant heat is efficiently radiated from this combustion surface.

  By the way, in a grill provided with an exhaust path behind the grill cabinet, a pair of left and right burners are fixed to the upper wall of the grill cabinet using the upper space of the grill cabinet. For this reason, the combustion surface of each burner is made horizontal and is directed directly downward. At this time, in general, in order to make the temperature distribution in the grill warehouse uniform, an infrared radiation area corresponding to the substantially left half of the mounting portion is set in the left burner, and the mounting portion is set in the right burner. An infrared radiation area corresponding to the substantially right half of the above is set, and the radiation area is formed uniformly over the entire mounting portion.

  However, when the size of the cooking object occupies most of the area on the mounting part, or when a large number of relatively small objects to be cooked are arranged on the mounting part and occupy the most area of the mounting part. When the radiation area is uniformly formed over the entire mounting portion, the food to be cooked is cooked well without unevenness, but in the case where cooking is performed with only one relatively small food to be cooked, etc. Most of the radiation region formed in the entire placement unit is wasted, and more fuel is consumed than necessary, which is uneconomical.

Therefore, when cooking with only a relatively small object to be cooked, etc., the burner is set to low heat to reduce fuel consumption, but this also forms the radiation area over the entire mounting part. Therefore, there is a disadvantage that the efficiency is poor and the fuel consumption cannot be sufficiently suppressed.

In actual cooking, when the food to be cooked is relatively large, or when a large number of relatively small foods to be cooked are arranged on the mounting section, the radiant heat is uniform over the entire mounting section with the combustion surfaces of both burners being horizontal. More efficient cooking is performed. On the other hand, when cooking a relatively small object to be cooked that is located only in the center of the mounting part when placed on the mounting part, the combustion surfaces of both burners are tilted inward to each other to be predetermined. Hold at an angle. By doing so, the infrared radiation area by the left burner and the infrared radiation area by the right burner are overlapped with each other in the center of the placement section, and are relatively small items to be cooked located only in the center of the placement section. The radiant heat can be concentrated on. And, since the radiant heat from both burners concentrates in the center of the mounting part, not only can the radiant heat be obtained even if the heating power of both burners is reduced, but sufficient cooking can be performed efficiently, and the food to be cooked Since wasteful radiation to the left and right end regions of the placement portion that is not placed is suppressed, fuel consumption can be reliably reduced. Thus, according to the present invention, it is possible to provide a grill that can be efficiently cooked in accordance with the size and quantity of the food to be cooked, and that can suppress fuel consumption satisfactorily.
Further, at this time, the tilt operation means is provided with a predetermined display corresponding to the radiation area formed on the mounting portion, so that the user confirms and operates the display when operating the tilt operation means. Therefore, it is possible to smoothly perform the work of tilting both burners to a favorable angle in accordance with the size and quantity of the objects to be cooked.

Moreover, Te present invention smell, the tilt operating means includes a further comprising a pair of driving a tilting of one burner of the burner, the link hand stage for tilting the other burners in conjunction with the tilting of the burner To do.
