Description

TECHNICAL FIELD The present invention relates to a gas table stove using a gas fuel such as city gas and liquid petroleum gas, a roasting machine equipped on a stationary stove, or a single roasting machine. Regarding

2. Description of the Related Art In a conventional roasting machine equipped with a gas table stove and a stationary stove, as shown in FIG. 4, a ceramic perforated plate or a wire mesh and a punching metal are used as flame hole plates near the ceiling of the heating chamber 1 as shown in FIG. There is one type of double-sided grill that includes a burner 2 and lower burners 5 that form Bunsen flames on both left and right sides of a lower portion of the heating chamber 1 through a grill 4 on which the food 3 is placed.

Problems to be Solved by the Invention In the double-sided grill shown in FIG. 4, the cooking target 3 is simultaneously cooked from the upper and lower sides by the radiation emitted from the upper burner 2 and the direct flame caused by the combustion of the lower burner 5. Was going on. In this case, since the lower burners 5 are located on the lower left and right sides of the food 3 to be cooked, the combustion heat from the lower burners 5 on the left and right cannot reach the central portion, and the temperature distribution directly below the grill 4 is convex to the left and right. Since the lower surface of the to-be-cooked object 3 has extreme burning unevenness on the left and right and in the central part, it is difficult to obtain a good cooking result. Further, since the upper burner 2 and the lower burner 5 are used at the same time, overheating occurs at various places in the heating chamber 1, and there is a tendency that the temperature of the door becomes high especially in the door and its vicinity. As a result of overheating, when water droplets or the like during cooking are scattered on the glass plate, it may be destroyed as the worst result.

Means for Solving the Problems In order to solve the above problems, the roasting device of the present invention has a grill for placing an object to be cooked in the center of a heating chamber having an opening / closing door, and heating below the grill. A lower burner is provided on both sides of the chamber, and an air blower is provided near the lower burner or integrally with the lower burner, in which an air ejection unit is arranged in parallel with the row of flame holes of the lower burner.
The end of the air ejection portion is provided so as to extend to the opening / closing door side from the end of the row of flame holes of the lower burner.

Operation According to the present invention, the hot air generated by the combustion in the flame hole array of the lower burner arranged on the lower side of the heating chamber is integrated with the lower burner or in the vicinity of the lower burner and the flame holes of the lower burner. The diffused air flow ejected from the air ejection part arranged in parallel with the rows spreads it over a wide area to keep the heat distribution under the mesh uniform, while opening and closing more than the end of the row of flame holes in the lower burner. An air curtain is formed near the opening / closing door by the air flow ejected from the air ejection portion extending to the door side, and as a result, the temperature of the opening / closing door can be lowered.

Example Hereinafter, one example of the roasting device of the present invention will be described with reference to the accompanying drawings.

1 and 2 show a roasting device according to the present invention, which has an opening / closing door 6 using a glass plate on the front surface, and an oil pan having a grill 8 on which a food 7 to be cooked is placed at the bottom. There is a heating chamber 10 in which 9 is arranged. An upper burner 11 having a metal mesh as a flame hole portion near the ceiling of the heating chamber 10 through the grill 8 and a flame hole for forming a Bunsen flame on both left and right lower portions of the heating chamber 10 through the grill 8 There is a lower burner 13 in which the rows 12 are arranged, and an air blower 15 in which the air jets 14 are arranged in parallel with the flame hole row 12 is provided directly above the lower burner 13 integrally with the lower burner 13, and at the rear of the air blower 15. The blower 16 is connected to the end. In addition, the air ejection unit 14
The end of the opening / closing door 6 side is provided so as to extend closer to the opening / closing door 6 than the end of the flame hole array 12 on the opening / closing door 6 side.
On the other hand, immediately above the air jetting portion 14, a vent hole plate 17 for controlling the direction of the air flow is provided in a symmetrical shape.

FIG. 3 shows a unit in which the lower burner 13 and the blower unit 15 are integrally formed. The left and right flame hole rows 12 and the right and left flame hole rows 12 are provided directly above the lower burner 13 to which the left and right flame hole rows 12 and the fire transfer flame hole portions 18 are connected. An air ejection unit 14 having air holes 19 arranged in parallel is arranged.

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

At the same time when the burner 11 and the lower burner 13 are ignited, diffused air is blown into the blower device 15 from the blower 16 and the diffused air flow ejected from the air holes 19 of the air ejection part 14 is directed to the wind direction plate 17.
Flow diagonally downward along the line of flame holes in the lower burner 13.
Similarly, the direction of the Bunsen flame formed by 12 is controlled obliquely downward. The left and right hot air streams generated as a result of the above gradually rise downward near the bottom of the grill 8 while being directed obliquely downward, and heat the lower surface of the food 7 while forming a substantially uniform heat distribution. On the other hand, the upper burner 11 forms a film-like flame in the flame hole part which becomes the mesh of the wire mesh, and radiates the radiation to the upper surface of the cooking target 7 below by the red heat of the wire mesh. At this point, it is possible to simultaneously heat the cooked object 7 from the upper surface with radiation and from the lower surface with a uniform hot air stream, and obtain a good cooking result.

Further, the opening / closing door 6 is located farther than the end of the flame hole row 12 of the lower burner 13.
The diffused air flow ejected from the air holes 19 of the air ejecting portion 14 extended to the side rarely touches the flame formed in the flame hole array 12, and the open / close door 6 and the flame hole array 12 as a cold air flow. An air curtain is formed between the opening and the end of the door, and as a result, the temperature of the glass plate of the opening / closing door 6 is lowered. Therefore, even if water drops or the like are splashed from the outside or a large amount of water drops are attached, the glass plate does not undergo rapid thermal contraction and can be prevented from being broken.

Further, since the air ejection portion 14 is arranged directly above the lower rear burner 13 and in parallel to the flame hole row 12 of the lower burner 13, the wind direction plate 17 can be directly installed in the air ejection portion 12, and as a result, the air ejection portion 14 The inclination of the jet of diffused air can be controlled very easily.

EFFECTS OF THE INVENTION (1) A grill for placing an object to be cooked is provided in the center of a heating chamber having an opening / closing door, lower burners are provided on both sides of the lower heating chamber of the grill, and flames in the vicinity of the lower burner or an integrated lower burner flame are provided. By installing an air blower with air jets arranged parallel to the row of holes, and by arranging the end of the air jets closer to the open / close door than the end of the row of holes in the lower burner, the flames generated on the left and right lower burners Control the direction of the heat to make the heat distribution in the lower part of the grill uniform, and to realize a uniform heating state from under the food to be cooked.
An air curtain can be created near the door to reduce the temperature of the door.

(2) By providing the air jet part above the flame hole array of the lower burner, a wind direction plate that controls the air flow can be mounted directly above the air jet part, and the outflow direction of the diffused air flow can be easily controlled. You can
