Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a baking device such as a grill.

(Prior art) As shown in FIG. 7, an opening D with an inward bulge C is provided in the side wall B of the firing chamber A, and the flame opening F of the gas burner E is directed into the firing chamber A from the opening D. In the case where the opening D faces the opening D, the flange C is generally formed by bending the upper side of the opening D. On the other hand, in some gas burners, the burner body G is tapered in order to make the flame at the tip of the burner approximately the same length as the flame at the base.In this case, the opening D is formed to be tapered to match the burner body G. Although the gap is substantially constant in the front-rear direction, the tip of the flange C formed by bending the upper side of the opening D is inclined (in the front-rear direction). Therefore, the gap between the tip of the sleeve C and the burner port F of the burner E was different in the front-back direction. (For example, see Utility Model Application Publication No. 58-41405.) (Problem to be solved by the invention) If there is a difference in the gap between the tip of the sleeve C and the flame opening F of the burner E in the front and rear directions as described above, the flame At the mouth, the air flow is different, resulting in a difference in the length of the flame, resulting in an inconvenience in distribution.

(Means to Solve the Problems) Therefore, the present invention provides an opening with an inward rim in the side wall of the firing chamber, and the flame opening of the gas burner faces the inside of the firing chamber from the opening. , the rim is formed by bending the upper side of the opening,
The burner has a tapered main body and a large number of flame ports located in the center of the main body in the longitudinal direction, and the gap between the tip of the flange and the flame ports is approximately It is made of the same gap.

(Example) An example of the present invention will be described with reference to the drawings. In FIGS. 1 to 4, 1 is a firing chamber, which in this example is composed of an upper half 2 and a lower half 4.
is fixed, but the lower half 4 is box-shaped and can be detached via the support member 3.

Reference numeral 5 denotes an opening provided in the side wall 6 of the firing chamber 1, which is a long opening extending in the front-rear direction. Reference numeral 7 denotes a rim portion formed by bending the upper side 51 of the opening 5 inward, and its tip 71 is lower than the upper side 51 and is inclined.

Reference numeral 8 denotes a gas burner, whose main body 81 is tapered and has a large number of flame ports 82 in the center of the main body 81 in the longitudinal direction. This gas burner 8
The flame port 82 faces into the firing chamber 1 from the opening 5.

The flame opening 82 of the gas burner 8 and the rim 7 above it
The gap 9 between the tip 71 is substantially the same in the front-rear direction. In this example, the burner body 81 is tapered, but by making the upper side 51 of the opening 5 horizontal, the tip 71 of the flange 7 and the flame port 82 are bent there.
The gap between the front and rear wheels was set to be approximately the same in the front-rear direction.

Reference numeral 10 denotes a pair of gas burners on the left and right sides above the firing chamber 1, which in this embodiment constitutes a double-sided firing machine with upper and lower heat. 11 is an object to be baked such as fish, and 12 is a saucer.

Next, to explain its action, when the burner 8 is ignited, the object to be burned 11 such as fish in the baking chamber 1 is heated.
is fired. At this time, air flows in through the opening 5. Gap 9 between the tip 71 of the sleeve 7 and the flame port 82
Since the gaps are approximately equal in the front-rear direction, the flow of air at the flame port 82 is approximately the same, and the inward extension of the flame is approximately the same length.

In the embodiment shown in FIGS. 5 and 6, the upper side 51 of the opening 5 is also inclined along the body of the burner 8. In the embodiment shown in FIGS. The rib portion 7 bent at this inclined upper side 51 is also inclined in the front-rear direction, so the tip portion 72 is further bent downward so that the tip 71 becomes horizontal.
The gap 9 with the burner port 82 is made substantially the same in the front and back direction.

In this case, since the brim 7 is also inclined forward, the oil dripping there tends to flow forward as well, which has the advantage of reducing dirt in the inner part.

(Effect of the invention) Even if the burner body is tapered and the upper side of the opening is horizontal and the gap with the bent part of the sleeve is different in the front and back direction, or the upper side of the opening is inclined to fit the burner body and the upper side of the sleeve is horizontal. Even if the bent part is tilted, the gap between the tip of the flange and the flame mouth, which has the greatest effect on the length of flame extension from the flame mouth, is made approximately equal in the front-rear direction, so the length of the burner flame can be maintained. have approximately the same length in the front-back direction, and a good distribution can be obtained.
