Description

[Detailed Description of the Invention] The present invention relates to a gas cooker having a tubular gas burner, and its purpose is to provide a gas cooker that can widen the grilling area by providing long and short gas flames.

Hereinafter, the present invention will be explained in detail based on an example of a grill incorporated into a gas stove. Reference numeral 5 denotes a cooking box forming the cooking chamber 1, which is open at the front.
The lower portions of both side plates 6 of the cooking box 5 are bent inward to form a burner storage chamber 7 outside the lower portion of the cooking box 5 in the front-rear direction.
Secondary air inflow holes 4, 4a are bored in the.
A tubular gas burner 2 is arranged in each burner storage chamber 7, and an upper secondary air supply passage 17 and a lower secondary air supply passage 17a are formed above and below the tubular gas burner 2. . A large number of flame holes 3, 3a are provided in the longitudinal direction of the tubular gas burner 2.
These flame holes 3, 3a are opened into the cooking chamber 1 through secondary air inflow holes 4, 4a. The flame holes 3, 3a are arranged in a staggered manner, with the flame holes 3 extending horizontally through the tubular gas burner 2 and the flame holes 3a extending diagonally downwardly through the tubular gas burner 2 alternately. The secondary air inflow holes 4, 4a are perforated in a staggered manner corresponding to the positions of the flame holes 3, 3a, and the adjacent two
The secondary air inflow holes 4 and 4a are in communication with each other. The flame 8 coming out from the flame holes 3, 3a is the secondary air inflow hole 4, 4.
The secondary air 9, 9a enters the cooking chamber 1 through the vertical center of the flame 8, and the secondary air 9, 9a is supplied from above and below the flame 8 through the secondary air supply passages 17, 17a. However, the flame 8 coming out from the flame hole 3a
As shown by the arrow in Fig. 2, the flame is ejected diagonally downward into the cooking chamber 1 and then upwards, and therefore, like the flame 8 coming out of the flame hole 3, it is ejected from the flame hole 13. Compared to the case where the flame 8 immediately extends upward from the flame 8, the length of the flame 8 in the horizontal direction can be extended. 10 is a soup saucer placed at the bottom of the cooking chamber 1, and 11 is a gas infrared burner. Tubular gas burner 2 and gas infrared burner 1
A receiving piece 13 for supporting the gridiron 12 is fixed in the cooking box 5 between the cooking box 1 and the cooking box 1. 14 is a cooking door.

Figure 6 shows the flow of the secondary air 9, 9a, and by forming the rising piece 15 as shown in figure a, the lower secondary air 9a flows along the rising piece 15 as shown by the arrow. The flame 8 flows upward into the cooking chamber 1, so that the flame 8 points upward and the horizontal extension of the flame 8 can be suppressed.Also, as shown in FIG. If the hanging length of the hanging piece 16 is made longer, the lower secondary air 9a will not flow upward as shown by the arrow, and the upper secondary air 9 will flow downward into the cooking chamber 1 along the hanging piece 16. Therefore, the flame 8 can be directed downward and the horizontal extension of the flame 8 can be lengthened. In this way, the shapes of the rising piece 15 and the hanging piece 16 change the flow of the secondary air 9, 9a and adjust the ejection angle of the flame 8. As a result, the flame hole 3,
In addition to adjusting the jetting angle of the flame 8 by changing the direction of penetration of the flame 8, it is also possible to increase the variety of jetting angles, making it possible to uniformly apply the flame 8 to the gridiron 12.

As mentioned above, the present invention is based on a tubular gas burner in which a plurality of flame holes facing horizontally and flame holes facing diagonally downward are alternately bored along the length of the tube wall on both sides of the lower part of the cooking chamber. Since the flames are arranged horizontally, the flames can be relatively short, and the flames pointing diagonally downward can be long. It has the advantage of being able to apply the flame evenly. The reason why multiple flame holes are arranged alternately in a staggered pattern is because if they are arranged alternately one by one, the adjacent flames will influence each other and become one flame, and long and short flames will not be formed. It is.
