Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner device for a grill portion equipped on a gas table stove using a gas fuel such as city gas or liquefied petroleum gas, or a stationary stove.

2. Description of the Related Art As shown in FIG. 5, a conventional grill has a ceramic perforated plate or a wire mesh mounted near the ceiling of the heating chamber 1, as shown in FIG.
A single-sided burning method in which the upper surface of the object to be heated 4 placed on the grill 3 is heated by the upper burner 2 which uses the punching plate as a combustion plate, as shown in FIG. An upper burner 6 of the same type as the one-sided burning system is mounted, and double-sided burning using both lower burners 9 for forming Bunsen flames arranged on the lower left and right sides of the object to be heated 8 placed on the grill 7 There is a method.

Problems to be Solved by the Invention In the single-sided burning method shown in FIG. 5, the upper surface of the object to be heated 4 is heated and cooked by the radiation emitted from the upper burner 2, and the object to be heated 4 is heated after a predetermined time has elapsed. Since the other side was turned over and cooked by heating, there was a problem that the cooking time was long as a result.

Further, in the double-sided burning method shown in FIG. 6, the upper and lower surfaces of the object 8 to be heated were simultaneously cooked by the upper burner 6 and the lower burner 9, respectively, but the lower burner 9 left and right the object 8 to be heated. Since it is located in the lower part of, the combustion heat from each of the left and right lower burners 9 could not reach the central part.
Therefore, the ambient temperature just below the grill 7 has a temperature distribution that is offset to the left and right as shown in FIG.
It was difficult to obtain good cooking results on the lower surface of the plate because of extreme burning unevenness on the left and right and in the center.

Means for Solving the Problems In order to solve the above problems, the burner device of the present invention is a flame hole plate in which flame holes are arranged in a row, and a wind hole plate in which air ejection holes are arranged in a row. A partition is provided between the flame hole plate, the partition,
A tubular portion formed by the partition wall and the air hole plate, in which the air hole plate is integrally molded and fitted, and the tubular portion formed by the flame hole plate and the partition wall is a burner tube into which a premixed gas of fuel and primary air flows. Is an air pipe, and an air direction control plate is provided in the vicinity of the air pipe, and an air blower from the outside is directly connected.

Effect of the Invention With the above configuration, the present invention controls the direction of the flame formed by the flame holes of the burner tube, and controls the air flow and the air direction ejected from the air ejection hole of the air tube that is directly above the burner tube and is directly connected to the blower. Controlled by the plate, the hot air generated by combustion can reach far from the burner tube flame holes.

Example An example in which the burner device of the present invention is applied to a double-sided grill will be described below with reference to the accompanying drawings.

FIG. 1 shows a burner device according to the present invention, in which a U-shaped air hole plate 10 has a large number of rows of air ejection holes 11, and a U-shaped partition wall 12 is also used. Immediately below the air hole plate 10, there is also a U-shaped flame hole plate 13, and a large number of flame holes 14 are arranged in a row. The air hole plate 10, the partition wall 12, and the flame hole plate.
13 are fitted together. On the other hand, a blower device 15 is directly connected to the rear of the air hole plate 10 to form a burner device 16 as a whole.

2 shows a vertical cross section of the portion A of the burner device 16 of FIG. 1, in which the tubular portion formed by the air hole plate 10 and the partition wall 12 is an air tube 17, and is formed by the partition wall 12 and the flame hole plate 13. The burner tube 18 is used as the tubular portion, and the wind direction control plate 19 is provided directly above the air hole plate 10.
(Not shown in FIG. 1) is installed. The blower unit 15 is connected to the air pipe 16 and disconnected from the burner pipe 17.

3 and 4 show the burner device shown in FIGS. 1 and 2.
In the front vertical cross-sectional view and the side vertical cross-sectional view when 16 is mounted on a double-sided grill, an upper burner 21 using a wire mesh as a radiation plate is provided near the ceiling of the heating chamber 20, and a cover is provided at the center of the heating chamber 20. The grill 23 on which the heated object 22 is placed, the burner devices 16 according to the present invention are provided on the left and right sides of the lower portion of the grill 23, and the saucer 24 is placed on the bottom of the heating chamber 20. Furthermore, the front of the heating chamber 20 is a door
The upper part of the rear part of the heating chamber 20 which is closed by 25 serves as an exhaust port 26 for combustion exhaust gas and oil smoke.

Next, the operation of the above configuration will be described.

The upper burner 21 and the burner pipe 17 of the burner device 16 are ignited,
At the same time, the air blower 15 starts blowing air into the air pipe 17 of the burner device 16, and the air jetted from the air jet hole 11 flows out in a certain direction along the wind direction control plate 18 and is formed in the flame hole 14 of the burner pipe 17. Direct the hot flame toward the diagonally downward direction.
To reach near the center of the lower part of the net to keep the atmospheric temperature immediately below the net 23 substantially uniform. At this point, radiant heat is added to the lower heating target 22 by the red heat of the wire mesh surface of the upper burner 21, and even heating is performed from both the upper and lower sides of the heating target 22 at the same time. Good cooking results can be obtained.

Also, if the size, shape, amount, etc. of the food to be cooked change,
Or if you want to apply it in a wider heating room,
It is possible to respond by switching the blowing capacity of the blower from strong to weak, turning on and off the blower at regular intervals, adjusting the wind direction angle of the wind direction control plate, etc., and similarly good cooking results can be obtained. To be

Effects of the Invention According to the burner device of the present invention, the following effects can be obtained.

(1) An air pipe formed by the air hole plate and the partition wall, a partition wall and a flame hole plate, in which a air hole plate having a large number of air ejection holes, a partition wall, and a flame hole plate having a large number of flame holes are integrally fitted. By integrating the burner pipe formed by, the air blower is directly connected to the air pipe, and the wind direction control plate is provided near the air hole plate, the direction of the flame formed by the burner pipe is controlled and A compact burner device capable of transporting the generated hot air to a distant place is obtained.

(2) When the burner device having the above-mentioned configuration is mounted as the lower heat source of the double-sided grill, a uniform heat distribution can be realized, so that only a good cooking result can be obtained even in a short time. In addition, it is possible to deal with a wider heating chamber than before.
