Description

  The present invention relates to a grill used for cooking a grilled fish or the like, or reheating a cold dish. In particular, the present invention relates to a grill provided with a lower fire burner.

Conventionally, in order to cook food such as fish, a pair of lower fire burners has been provided in the lower part near the side wall of the grill warehouse, and a grill net has been provided above the lower fire burner for placing the food. The grill is known. In this type of grill, each lower fire burner is provided with a plurality of flame outlets that open toward the center of the grill cabinet at a predetermined pitch in the front-rear direction, and the lower flame burners are opposed to each flame outlet. As shown in FIG. However, in the grill as described above, the combustion exhaust formed by the frames from the opposed flame ports press against each other, and it is difficult for the frames to stably reach the center of the grill cabinet. Therefore, for example, a grill has been proposed in which the center axis of the lower flame burner of one lower flame burner and the center axis of the lower flame burner of the other lower flame burner are arranged so as to be displaced from the vertical direction (for example, Patent Documents) 1).
Japanese Utility Model Publication No. 6-79433

  By the way, since a plurality of wires are usually arranged on the left and right in the grill to place the food, the frame extending in the horizontal direction from the flame opening of the lower burner is provided with the wires. It is formed in the same direction as the direction in which it is present. Therefore, when a wire is located on the frame, the supplied thermal energy is transmitted to the cooked product through the wire. Therefore, there is a problem that the portion where the frame and the wire overlap each other is insufficiently heated and the baking performance is lowered, and the overlapping portion is difficult to be colored. Although it is conceivable to increase the amount of gas jetted in order to color the cooked food, in this case, the portion where the frame and the wire are not overlapped is excessively heated, so that scorching tends to occur. Also, when the wire is located on the frame, the wire is partially heated, so the temperature of the wire rises locally, making it easier for the wire and the food to stick together, and cooking when returning or taking out the food. There is a problem in that part of the object is peeled off and the beauty after baking is impaired. Furthermore, recently, in order to prevent sticking between the cooked food and the grill, wire treated with a fluorine-based coating may be used. However, the coating is easily peeled off by local heating as described above. Therefore, there is also a problem that the durability of the grill is lowered.

  The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a grill that can uniformly heat a cooked food, has excellent aesthetics after baking, and can suppress deterioration of the wire. There is.

The present invention provides a grill ware, a lower fire burner extending in the front-rear direction when the front opening of the grill ware is in the front , a lower portion near the side wall of the grill ware, and a cooked food above the lower fire burner. A grille having a plurality of wires to be placed and a grill arranged in the left-right direction of the grill warehouse ,
The waning burner includes the plurality of main flame port opening toward the center of the grill box at a predetermined pitch in the longitudinal direction, and a flame holding opening adjacent to the lower of the main flame hole,
The lower fire burner and the grill net are arranged so that the main flame port of the lower fire burner and the wire rod of the grill net do not overlap when viewed from above.
According to the grill, the lower flame burner and the grill net are arranged so that the main flame outlet of the lower flame burner and the wire rod of the grill net do not overlap when viewed from above. The contact between the frame and the wire can be reduced.

The lower fire burner has an upper burner plate, a lower burner plate, and a flame holding plate, and these are integrally joined to keep the main flame opening and the lower side of the main flame opening. A flame mouth is formed,
It is preferable to have a protrusion in a region of the flame holding port facing the main flame port.
According to the grill, since the lower flame burner has the protrusion in the region facing the main flame opening of the flame holding opening, the sleeve fire formed by the flame holding opening is divided into left and right by the protrusion. For this reason, the flame from the main flame opening does not interfere with the flame, the enlargement of the frame can be prevented, and the contact between the frame and the wire can be further reduced.

  As described above, according to the present invention, the cooked product can be heated uniformly, and the appearance after baking is excellent, the deterioration of the wire can be suppressed, and the durability of the grill can be improved.

Hereinafter, the grill of this embodiment will be described with reference to the drawings.

  A handle 160 protrudes from the front lower portion of the open / close door 16. When the handle 160 is gripped and the open / close door 16 is pulled out, the pan mounting tray 19 continuously provided on the back surface of the open / close door 16 becomes the grill pan 13 and the grill 12. At the same time, it is pulled out. An exhaust passage 15 for exhausting combustion exhaust gas in the grill cabinet 1 to the outside is connected to the back of the grill cabinet 1, and an upper fire burner 10 is disposed on the ceiling of the grill cabinet 1. Yes.

  In addition, as shown in FIG. 2, the left and right side walls 21, 21 of the grill cabinet 1 have an air intake 22 for introducing outside air above the lower fire burner 4, and outside air below the lower fire burner 4. And an air intake 23 for introducing the air. A base end portion of the upper secondary air guide plate 5 is welded to the upper side of the upper air intake port 22 in each of the side walls 21 and 21, and approaches the upper region of the combustion portion of the lower fire burner 4. Yes. The upper secondary air guide plate 5 is continuous along substantially the entire front-rear direction of the lower fire burner 4, and has a vertical portion 50 welded to the side walls 21, 21 of the grill 1, and the front It includes an inclined portion 51 that approaches the lowering, and a hanging plate 52 that bends downward from its tip. On the other hand, on the lower side of the lower air intake 23 formed in each side wall 21, 21, the base of the lower secondary air guide plate 6 squeezing upward toward the lower area of the combustion part of the lower fire burner 4. The ends are welded. The lower secondary air guide plate 6 is continuous along substantially the entire front-rear direction of the lower fire burner 4, and the front is directed toward the front of the vertical portion 60 welded to the side walls 21, 21 and the lower fire burner 4. An inclined portion 61 that protrudes upward is provided. Secondary air passages 54 and 64 are formed between the upper and lower secondary air guide plates 5 and 6 and the lower fire burner 4. The secondary air flow guided from these upper and lower secondary air guide plates 5 and 6 is configured to allow the frame to fly farther in the horizontal direction in the space below the grill net 12.

  In addition, a pair of lower fire burners 4 and 4 are disposed in the lower part near the side walls 21 and 21 of the grill cabinet 1 and below the grill net 12. A plurality of main flame openings 40 are formed at a predetermined pitch and open toward the center of the grill cabinet 1. The main flame outlets 40, 40 formed in one lower flame burner 4 and the main flame outlets 40, 40 formed in the other lower flame burner 4 do not face each other. The lower fire burner 4 is disposed with a half-pitch shift in the front-rear direction.

  FIG. 3 is a top view showing an arrangement state of the lower fire burner 4 and the grill 12 in the grill warehouse 1 of FIG. The main flame opening 40 and the wire 121 are formed so that the pitch of the wire and the pitch between the wires 121 and 121 are the same.

All of the main flame ports 40 of the fire burner 4 are arranged so as not to overlap the wire rod 121 of the grill 12. In this way, the lower flame burner 4 and the grill net 12 are arranged so that the main flame outlet 40 and the wire 121 do not overlap, so that the frame MF from the main flame outlet 40 faces the center of the grill cabinet 1. Even if it extends, the contact of the frame MF with the wire 121 can be reduced. Thereby, since a foodstuff can be heated uniformly, baking performance can be improved and baking unevenness can be reduced. In addition, since the wire 121 is not locally heated by the frame MF, the burning of the cooked product on the wire 121 is reduced, and a cooked product in a clean baked state can be obtained. And even if the wire 121 is processed by the fluorine-type coating, since the wire 121 is not locally heated by the flame | frame MF, durability of the grill 12 can be improved.

FIG. 4 is a perspective view showing a preferred example of the lower fire burner of the present embodiment, FIG. 5 is an exploded perspective view, FIG. 6 is a partial sectional perspective view, and FIG. 7 is a partial top view.
As shown in FIGS. 4 to 6, the lower fire burner 4 is a pipe formed by combining an upper burner plate 46 and a lower burner plate 47 obtained by drawing a sheet metal into a bowl shape. The upper horizontal flange portion 460 protruding forward is formed with an upper curved portion 461 that opens forward at a predetermined pitch in the front-rear direction. Further, a lower horizontal flange portion 470 protruding forward from the lower burner plate 47 is overlapped with the upper horizontal flange portion 460 of the upper burner plate 46, thereby forming the upper horizontal flange portion 460 of the upper burner plate 46. The main flame ports 40 are formed at a predetermined pitch between the upper curved portion 461 and the lower horizontal flange portion 470 of the lower burner plate 47. The main flame opening 40 communicates with the gas passage 43 of the lower flame burner 4 and is configured to be supplied with gas from the gas passage 43.

  A flame holding plate 48 having a lower flange portion 480 substantially parallel to the lower horizontal flange portion 470 is joined to the lower burner plate 47 from below, and is attached to the lower flange portion 480 protruding forward of the flame holding plate 48. Is provided with a step 481. Although not shown, the lower horizontal flange portion 470 of the lower burner plate 47 and the lower flange portion 480 of the flame holding plate 48 are temporarily fixed by spot welding, and the periphery of the base end portion of the flame holding plate 48 is the lower burner. The lower surface of the plate 47 is joined by welding. Since the communication hole 49 is formed in the lower burner plate 47, as shown in FIGS. 4 and 6, the lower horizontal flange portion 470 that protrudes in front of the lower burner plate 47 and the flame holding plate 48 protrude in front. When the lower flange portion 480 is overlapped, a certain slit-like gap is formed between the lower horizontal flange portion 470 and the lower flange portion 480, whereby the lower horizontal flange portion 470 and the lower flange portion 480 are A flame-holding port 45 that opens forward is formed adjacent to the main flame port 40 in the front-rear direction.

  As shown in FIGS. 4 to 6, when the flame holding port 45 is formed in the lower flange portion 480 of the flame holding plate 48 as described above, the main flame port 40 in the flame holding port 45 and A columnar protrusion 482 having a height substantially the same as the height of the flame holding port 45 and a width smaller than the width of the main flame port 40 is provided in the opposed region. By providing this projection 482, as shown in FIG. 7, the sleeve fire SF from the flame holding port 45 is partly projected in the region facing the main flame port 40 of the flame holding port 45. Can be prevented from forming the sleeve fire SF near the center in the width direction of the frame MF formed in the main flame outlet 40. Therefore, the interference of the sleeve fire SF to the frame MF of the main flame outlet 40 can be reduced, and the enlargement of the frame MF can be reduced. As a result, the frame MF does not spread upward where the wire is located, and the contact between the frame MF and the wire 121 can be further reduced. Since the protrusion 482 has a width smaller than the width of the main flame opening 40, the sleeve fire SF diverted by the protrusion 482 is formed at both ends in the width direction of the frame MF of the main flame opening 40. The ignition of the gas ejected from the main flame outlet 40 is not hindered. Note that the protrusion 482 is not limited to a cylindrical shape, and may be formed in an arbitrary shape such as a conical shape or a cubic shape.

  In the lower fire burner, the protrusion 482 is formed at a position 2 mm inward from the gas outlet end 451 of the flame holding port 45. By forming the protrusion 482 inward of the gas outlet end 451 of the flame holding port 45 in this way, the sleeve fire SF can be diverted before the sleeve fire SF spreads. Interference of the sleeve fire SF to the frame MF can be reduced.
