Description

DETAILED DESCRIPTION OF THE INVENTION (Prior Art) Conventionally, an upper-fire burner and a lower-fire burner are provided above and below a firing chamber, an exhaust outlet is opened at the rear of the firing chamber, and a cooked product is provided between the burners. Which is to be baked,
A normal-fire pilot burner provided on the exhaust outlet side of the firing chamber with both normal flame ports facing the upper burner and the lower flame burner, and a vertical transfer flame port connecting the regular flame ports. Is known.

(Issues to be solved by the invention) However, the ignition of this kind of firing device is performed by igniting the upper burner with a flame from the flame mouth of the pilot pilot burner facing the upper burner from the lower burner. In the case of a vehicle equipped with an ignition pilot burner, the flame from the flame port becomes unstable due to the influence of the exhaust gas from the ignition pilot burner, and sometimes the blowout is caused. There is a problem such that the ignition performance of is deteriorated.

The object of the present invention is to obtain a calciner with a pilot fire burner that does not have such problems.

(Means for Solving the Problems) In order to achieve such an object, the present invention comprises an upper-fire burner and a lower-fire burner above and below the firing chamber, and an exhaust outlet at the rear of the upper-burn burner of the firing chamber. And the cooking is performed in the middle of both the burners, and the normal flame mouths respectively facing the upper burner and the lower burner on the exhaust outlet side of the firing chamber, and the normal flames. By providing a normal-fire pilot burner having a flame transfer flame port in the vertical direction that connects the mouths, and by igniting the transfer of heat to the upper-fire burner via the normal-fire pilot burner, A windbreak plate that forms a windless space is provided in the flame formation portion extending from the lower surface to the normal flame mouth facing the upper fire burner.

(Operation) In the normal-fire pilot burner equipped with the above-mentioned configuration, the flow of exhaust gas from the lower-flame burner or the like flowing along the lower surface of the upper-fire burner toward the exhaust outlet side is controlled by the windbreak plate to over-fire. Since a windless space is formed in the flame forming portion extending from the lower surface of the burner to the normal flame mouth, the flame from the normal flame mouth facing the upper flame burner is stabilized without acting on the flame in the windless space.

(Embodiment) An embodiment of the present invention will be described with reference to the attached drawings.

In the drawings, 1 is a calciner, 2 is a calcining chamber provided in the calciner 1, 3
Is an opening in front of which food and drink A can be put in and out.
Is a door provided in this, 5 is an exhaust port provided in the rear part of the top plate 6 on the upper surface of the baking device 1, and in the baking chamber 2 above and below it,
An upper flame burner 7 and a lower flame burner 8 are provided respectively, and an exhaust outlet 9 communicating with the exhaust port 5 is opened at the rear of the upper flame burner 7 of the firing chamber 2 and in the middle of both burners 7, 8. A shelf 10 on which the food A is placed is further provided, and an exhaust outlet 9 of the baking chamber 2 is further provided.
On the side, there is provided a normal-fire pilot burner 14 having normal flame ports 11 and 12 facing the upper flame burner 7 and the lower flame burner 8, respectively, and a vertical flame port 13 connecting both the regular flame flames 11 and 12. It was

Reference numeral 15 denotes an exhaust passage connecting the exhaust port 5 and the exhaust outlet 9.

The configuration so far is not particularly different from the conventionally known configuration.

In this invention, since the windbreak plate for forming a windless space is provided in the flame forming portion extending from the lower surface of the upper fire burner to the normal flame mouth facing the upper fire burner, further explanation will be given below. The fire burner 7 is composed of a plate burner having a ceramic plate 7b provided with a large number of flame holes 7a on its lower surface, and the lower surface of the ceramic plate 7b on the exhaust outlet 9 side, that is, the ceramic plate.
A windbreak plate 16 having an opening 16a provided only on the front side on the lower surface of the rear portion of 7b and bent in a U-shape shown in FIG. 4 from a normal flame port 11 facing the upper burner 7 of the normal pilot pilot burner 14. It was provided so as to surround.

In addition, 17 is an ignition pilot burner for igniting by an ignition electrode (not shown) to carry out ignition transfer ignition to the lower fire burner 8, and 18 is a thermocouple for detecting misfire which faces the flame mouth 13 of the normal fire pilot burner 14. Indicates.

At this time, as described above, the flow of the exhaust gas from the lower fire burner 8 flowing along the lower surface of the upper fire burner 7 is obstructed by the windbreak plate 16 so that the lower flame of the upper heat burner 7 flows to the normal flame outlet 12 from the lower flame burner 7. Since a windless space is formed in the flame forming portion, the flow of the exhaust gas does not act on the flame from the normal flame port 12 of the normal pilot pilot burner 14 formed in the windless space, and the flame is stable. To do.

The position of attachment of the windbreak plate 16 is not limited to the rearmost part of the upper flame burner 7, but may be a position that can obstruct the flow of exhaust gas from the lower flame burner or the like generated in the vicinity of the flame from the normal flame port 11. It may be located further forward, and the shape of the windbreak plate 16 may be such that the flow of exhaust gas from the lower flame burner or the like generated in the vicinity of the flame from the normal flame port 11 facing the upper flame burner 7 of the normal pilot pilot burner 14. As long as it interferes with the above, it is not limited to the above, and it may be, for example, a semicircular shape, a triangular shape, or a linear shape. It may be attached to.

(Effects of the Invention) As described above, according to the present invention, the flow of exhaust gas from the lower flame burner flowing along the lower surface of the upper flame burner is obstructed by the windbreak plate, and the normal flame outlet opens from the lower surface of the upper flame burner. Since a windless space is formed in the flame forming part over the above, the flow of the exhaust gas does not act on the flame from the normal flame port of the normal combustion pilot burner formed in the windless space, and the flame is stabilized. , It has the effect of preventing misfiring to the upper fire burner.
