Description

[Detailed Description of the Invention] Industrial Application Field The present invention is applicable to gas stoves using gaseous fuel such as city gas or liquefied petroleum gas, gas cookers installed in stationary stoves, or single gas cookers. Regarding.

BACKGROUND OF THE INVENTION In a conventional gas cooker with double-sided grilling method, as shown in Fig. 3, an upper burner 2 is installed on the ceiling of the heating chamber l with a combustion plate made of a perforated ceramic plate, wire mesh, punched metal, etc.
is installed and the food to be cooked 3 is placed through the grill w44,
There is one that is equipped with lower burners 5 that form Bunsen flames on both left and right sides of the lower part of the grill 4, and is equipped with an oil pan 6 at the lowest part of the heating chamber 1.

Problems to be Solved by the Invention In the gas cooker shown in FIG. 3, both the front and back sides of the object 3 to be cooked are heated and cooked simultaneously by the upper burner 2 and the lower burner 6, respectively. In this case, since there are two heat sources, the upper burner 2 and the lower burner 5, in the upper and lower parts of the heating chamber 1, the temperature inside the heating chamber 1 not only increases, but also the flame formed by the lower burner 5 directly As the food to be cooked 3 is heated, the part of the food to be cooked 3 that is exposed to the direct flame ignites, and the oil, etc. on the food to be cooked 3 becomes a new ignition source, and the oil, etc. that has accumulated in the oil pan 6 during cooking ignites. There were cases where the ignition source of the food to be cooked 3 fell and a flaming flame was formed on the oil pan 6, turning the entire heating chamber 1 into a combustion chamber. In addition, the heat distribution at the bottom of the gridiron 4 is such that the temperature is low near the center of the gridiron 4 and the temperature is extremely high on the left and right sides.
It was difficult to obtain good cooking results.

Means for Solving the Problems In order to solve the above-mentioned problems, the gas cooker of the present invention is provided with a grill for placing the food to be cooked in the center of the heating chamber, and lower burners on both sides of the heating chamber below the grill. A blower device having an air blowing part is provided near the lower burner or integrally with the lower burner, and an oil drain plate having a large number of oil drain holes is placed on an oil pan provided at the lowest part of the heating chamber. Near the center of the oil cutting plate,
It has protrusions parallel to the rows of flame holes in the lower burner.

According to the above-described structure, the hot air flow generated by the air flow sent out by the blower installed near the lower burner or integrally with the lower burner and the flame formed by the flame holes of the lower burner on both sides is heated by the oil. The oil is rectified and rises while colliding with the protrusions of the oil cutting plate placed on the saucer from opposite sides. Therefore, a uniform heat distribution is formed near the bottom surface of the object to be cooked, and uneven cooking does not occur on the bottom surface of the object, and good cooking results can be obtained. In addition, since the lower part of the food to be cooked is heated by hot air flow rather than direct flame, it is rare for the food to catch fire. Since the temperature of the oil pan can be kept low, the oil accumulated in the oil pan will not catch fire, and safety can be maintained.

EXAMPLE Hereinafter, an example of the gas cooker of the present invention will be described based on the accompanying drawings.

FIG. 1 shows a gas cooker according to the present invention, in which there is a grill M49 near the center of the heating chamber 7 on which a food to be cooked 8 is placed;
Near the ceiling of the upper heating chamber 7 of the grill 9, there is an upper burner 10 having a wire mesh as a radiant plate, and on both left and right sides of the lower heating chamber 7 of the grill 9, there are lower burners 12 having a large number of flame hole rows 11. There are many long oil holes 13 at the bottom of the heating chamber 7.
There is an oil tray 15 on which an oil purifier 14 having a shape is placed. Further, a blower device 17 having an air jet section 16 is provided near the lower burner 12 or integrally with the lower burner 12 . Furthermore, a protrusion 18 is provided near the center of the oil cutting plate 14 in parallel with the numerous flame hole rows 11 of the lower burner.

FIG. 2 is a perspective view of the oil purifier vi 15 according to the present invention, and a projection 18 provided near the center is provided with a large number of elongated oil cut holes 13.

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

When the upper burner 10 and the lower burner 12 are ignited and a flame is formed in the numerous flame hole rows 11 of the lower burner 12,
At the same time, air is introduced into the air bag 217, and the air blowing section 1
6. An air flow is generated. The flame and hot air formed in the numerous flame hole rows 11 of the lower burner 12 follow the flow direction of the above-mentioned air flow, collide with the protrusion 18 formed near the center of the oil sump 114, and rectify the flame. It reaches near the center of the lower part of the gridiron 9 while being affected by the action, and maintains a substantially uniform temperature distribution at the lower part of the gridiron 9. At this point, the upper burner 10
Radiant heat is applied to the upper surface of the lower object to be cooked 8 by the red heat on the surface of the wire mesh, and a uniform heating state is realized from both the upper and lower sides of the object to be cooked 8 at the same time. As cooking progresses, oil leaches from the food to be cooked 8 and falls onto the oil cutting plate 14 at the bottom.
By passing through a large number of elongated oil drain holes 13, it efficiently falls onto the lower oil pan 15. Most of the oil that has fallen from the food to be cooked 8 in this way is absorbed by the oil drain plate. 14
The proportion of oil remaining on the oil cutting plate 14 is considerably small. In addition, the oil that has fallen and accumulated on the oil pan 15 is also different from the flame formed by the lower burner 12 in the oil cleaner 1.
4, so it does not heat up and does not evaporate.
Since the flame of the lower burner 12 does not directly contact the lower part of the object 8 to be cooked, the object 158 to be cooked is almost never ignited. A safe and uniform cooking condition is created.

Effect of the invention According to the gas cooker of the present invention, the following effects can be obtained.

At the lower left and right sides of the heating chamber, which is equipped with a grill on which the food to be cooked is placed, is equipped a lower burner equipped with a blower device having an air jet section nearby or integrally, and at the lowest part of the heating chamber, a large number of oil By installing an oil pan on which an oil cutting plate with cut holes and protrusions parallel to the row of flame holes of the lower burner is mounted near the center thereof, the flame and hot air formed by the lower burner can be The air flow ejected from the air jetting part reaches the center of the lower part of the grill 9, and at the same time, the oil purifying protrusion rectifies the air in the - direction to maintain a uniform temperature at the lower part of the grill 9. , and the oil content of the food to be cooked 8 is allowed to fall onto the oil tray through the many oil drain holes of the oil drain plate, and by blocking the heat from the lower burner, ignition phenomenon in the heating chamber is prevented, and the oil content is safely and evenly distributed. It is possible to achieve a perfect cooking condition.
