Abstract

PROBLEM TO BE SOLVED: To improve an igniting performance of an upper burner of a grill cooker. SOLUTION: The cooking equipment comprises a pilot guide 25 for broadening a fame of an igniting pilot burner 23 to an upper burner 19 of a grill cooker. Thus, a flame energy of the burner 23 is weakened. The flame is spread to the entirety from a depth side of the burner 19 to a front surface side. Thus, the burner 19 can be effectively ignited even with a gas having a low Wobbe index or a low gas pressure.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking appliance provided with a creel cooker for cooking food such as fish with a heat source of a gas burner.

[0002]

2. Description of the Related Art FIGS. 5 to 7 show the structure of a conventional grill cooking appliance equipped on a gas stove and a stationary stove. FIG. 5 is a side sectional view of a grill cooker.
Is a sectional view of the front, and FIG. 7 is a top view.

[0003] Reference numeral 1 denotes a heating chamber for storing a food 2 such as fish.
An openable and closable grill door 3 is provided at the front opening, and an upper burner 4 having a ceramic perforated plate or a wire mesh, a perforated plate made of punching metal, a gas pipe 5 for the upper burner 4 and a nozzle 6 are provided at the upper portion in the heating chamber 1. Is arranged.

[0004] An opening 7 is provided in the center of the upper side of the heating chamber 1 in the front and rear direction, and a pilot burner 8 and a pilot pipe 9 for igniting the upper burner 4 are arranged so that the flame is directed obliquely toward the front. Is aimed at. Also,
On the inner bottom of the heating chamber 1 is a saucer 10 for filling with water during cooking.
And a grill 11 on which the food 2 is placed and placed on the saucer 10
Is provided.

On the other hand, secondary air for combustion of the upper burner 4 flows from an intake portion provided around the grill door 3 except for the upper portion thereof, and exhaust gas after combustion is provided at a rear portion of the heating chamber 1. The exhaust port 12 is configured to be higher on the exhaust port 12 side so that the exhaust gas is discharged from the exhaust port 12 and the exhaust pipe 13 and the exhaust gas is easily discharged from the exhaust port 12 and the exhaust pipe 13.

[0006]

However, in such a grill cooker, when a gas having a low Wobbe index or a low gas pressure, for example, 4A, 4B, or 4C gas, is spouted from the nozzle 6 of the upper burner 4 with such a grill cooker. The burned gas is the upper burner 4
And the gas is ejected from the flame hole 4a, but the gas ejection speed is slow and the gas does not reach the entire flame hole 4a.

Further, since the exhaust port 12 is higher, the air flows from the periphery of the grill door 3 to the exhaust port 12 side, and further, the flame 8 of the pilot burner 8 for ignition.
The momentum of a is strong, and the ejection of gas from the flame hole 4 is suppressed,
There is a problem that the upper burner 4 is not ignited even if the flame 8a of the pilot pilot burner 8 reaches the flame hole 4a of the upper burner 4.

As a countermeasure, there is a means for directing the direction of the ignition pilot burner 8 to the rear, but there is a problem that the flame 8a of the ignition pilot burner 8 causes the flame to overflow from the exhaust stack 13 to the outside.

In general, a heating cooker is frequently used on a daily basis, and is required to have good ignitability and good usability and high reliability. Therefore, an object of the present invention is to improve the performance of igniting an upper burner of a grill cooker.

[0010]

The grill cooker according to the present invention is provided with a pilot guide for spreading the flame of the pilot burner for igniting the upper burner.

According to the present invention, it is possible to reliably ignite the upper burner of the grill cooker with respect to various gases and gas pressures.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be practiced by adopting the structure described in claim 1. That is, a heating chamber for heating the cooked food, an upper burner is provided above the heating chamber, and an ignition pilot burner for the upper burner and an opening corresponding to the ignition pilot burner are provided on a side surface, and the opening is provided. With a configuration having a pilot guide that extends the flame of the ignition pilot burner by inclining the upper burner side, the ignition performance of the grill cooker to transfer the fire from the ignition pilot burner to the upper burner is improved. be able to.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing a grill cooker according to an embodiment of the present invention, FIG. 2 is a top view of the same, and FIG. 3 is a perspective view of a pilot burner and a pilot guide. FIG. 4 is a perspective view of a built-in cooker equipped with the grill cooker.

Reference numeral 14 denotes a built-in cooker provided with a grill cooker 15. Reference numeral 16 denotes a heating chamber for storing a food 17 such as fish, and a grill door 18 which can be opened and closed is provided at the front opening,
An upper burner 1 having a ceramic perforated plate or a wire mesh and a perforated plate made of punched metal is provided in an upper portion of the heating chamber 16.
9. Gas pipe 20 and nozzle 2 for upper burner 19
1 is arranged.

An opening 22 is provided at the center of the upper side surface of the heating chamber 16 in the front and rear direction, and a pilot burner 23 and a pilot pipe 24 for igniting the upper burner 19 are arranged so that the flame is directed obliquely toward the front. Is turned.

Further, the flames 23a of the ignition pilot burner 23 are located at the back and front of the upper burner 19, and the upper burner 19 is controlled so as to suppress the momentum of the flame 23a.
A pilot guide 25 having an inclination on the side is provided.

On the inner bottom of the heating chamber 16, a saucer 26 for putting water during cooking and a food 17 are placed.
6 is provided with a grill 27. On the other hand, the secondary air for the combustion of the upper burner 19 flows in from an intake portion provided around the grill door 18 except for the upper portion.

After the combustion, the exhaust gas is discharged from the louver 30a of the top plate 30 through an exhaust port 28 and an exhaust pipe 29 provided at the rear of the heating chamber 16. In order to make it easier for the exhaust gas to be discharged from the exhaust port 28 and the exhaust pipe 29, the exhaust port 28 side is configured to be higher.

The flame 23 of the pilot burner 23 for ignition
The moment “a” impinges on the pilot guide 25, the momentum weakens, and spreads entirely from the back side to the front side of the upper burner 19, so that the flame a is transferred to the flame hole 19 a of the upper burner 19 and the ignition is reliably performed.

[0021]

As described above, according to the present invention, by providing a pilot guide for spreading the flame of the pilot burner for ignition to the upper burner of the grill cooker, the flame of the pilot burner for ignition can be weakened. By spreading the upper burner from the back side to the front side, the fire can be transferred to the upper burner satisfactorily and the ignition can be reliably performed.

In addition, even when the gas has a low Wobbe index and low gas pressure, the upper burner can be reliably ignited.
