Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smokeless grill for grilling and cooking foods such as meat and fish.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional smokeless oven, for example. The smokeless oven has a pair of left and right side walls 1 on the paper surface and side walls 2 on the front and rear sides of the paper surface, and is formed of a box body whose upper and lower surfaces are open. The gas burners 3a and 3b are provided in two upper and lower stages on the opposing surfaces of the pair of opposing side walls 1 among them. A net 5 is wrapped around the upper ends of the side walls 1 and 2, and food 4 such as meat and fish is placed on the net 5. Further, a pan 6 is disposed on the lower surface side of the side walls 1 and 2, and the pan 6 stores water.

In such a smokeless boiler, when the gas burners 3a and 3b are ignited, food materials 4 such as meat and fish on the net 5 are burned by the thermal power. At this time, for example, juice falls from the food material 4 such as meat or fish, but this juice falls directly onto the pan 6 without touching the gas burners 3a and 3b provided on the side wall 1. Therefore, it is possible to prevent the juice from sticking to the gas burners 3a, 3b and prevent the juice from burning and generating smoke.

In the above-described smokeless oven, the lower surface of the box and the pan 6
And an opening 9 is formed there. If the opening 9 is formed between the lower surface of the box and the pan 6 in this manner, the warmed air inside the box rises, and outside air flows into the box from the opening 9. , Natural convection occurs. Therefore, oxygen is supplied to the box one after another, and the combustion efficiency can be improved. If the opening 9 through which air can flow in is not formed, exhaust gas generated by combustion of the gas burners 3a and 3b accumulates in the box. When the exhaust gas accumulates in the box, the amount of oxygen is reduced, and the combustion efficiency is remarkably deteriorated.

[0005]

In the above-described conventional smokeless baking apparatus, air flows from the opening 9 below the box. Then, the air flowing from the opening 9 is warmed and rises in the box body, and at this time, as shown by a two-dot chain line 8 in FIG. 5, the air is pushed out by the gas pressure discharged from the gas burners 3a and 3b. While rising, it concentrates near the center of the net 5.

However, the air that flows one after another from the opening portion 9 rises when it is slightly warmed to room temperature. In other words, the air that rises in the box body rises toward the vicinity of the center of the net 5 only at a temperature slightly higher than room temperature, though it is warmed.

When the rising air is concentrated near the center of the net 5, only the temperature near the center becomes lower than the temperature near the ends, as shown in FIG.
Then, if the temperature distribution varies on the net 5, the food 4 such as meat or fish will have uneven grilling. An object of the present invention is to provide a smokeless boiler that allows air to flow in to improve combustion efficiency and that can use the inflowing air to arbitrarily adjust a temperature distribution for baking food. is there.

[0008]

According to the present invention, a wall facing each other, a gas burner provided on the opposite surface of the wall, an air inlet formed in the wall, and a top end of the facing wall are provided. It is assumed that there is provided a smokeless boiler which is provided with a support material such as a net or a skewer for supporting food materials such as fish, and is configured to bake the food materials such as meat and fish supported by the support material by the heat of a gas burner. The first invention is characterized in that the air inlets are arranged vertically with at least one gas burner interposed therebetween. The second invention is characterized in that, in the first invention, the opening area of the air inlet is adjustable. The third invention is characterized in that in the first and second inventions, a configuration is adopted in which warm air is introduced from an air inlet.

[0009]

1 and 2 show an embodiment of a smokeless baking apparatus according to the present invention. The following description will focus on the differences from the above-described conventional example of the smokeless oven, and the same components as those in the conventional example will be assigned the same reference numerals, and detailed description thereof will be omitted. As shown in FIGS. 1 and 2, the smokeless oven has four side walls 1 and 2 and is formed of a box having an upper surface opened. Unlike the conventional example, the lower surface is opened to form an open portion 9. Closed without forming. And the bread 6 is arrange | positioned at the bottom part of this box.

On a pair of side walls 1 opposed to each other, rod-shaped gas burners 3a, 3
b is provided. Then, on each side wall 1, these gas burners 3a, 3b are arranged in upper and lower two stages. Further, the side walls 1 are formed with elongated air inlets 7a to 7c arranged vertically above and below the gas burners 3a and 3b. Therefore, on each side wall 1, the air inlet 7a, the gas burner 3a, the air inlet 7b, the gas burner 3b, and the air inlet 7c are arranged in this order from above to below. Note that a pair of side walls 1 of this embodiment
The walls oppose each other in the present invention.

Next, the operation of the smokeless oven of this embodiment will be described. When the gas burners 3a and 3b are ignited, the warmed air inside the box rises, and outside air flows into the box from the air inlets 7a to 7c, and natural convection is generated. Here, the air flowing in from the uppermost air inlet 7a is warmed and rises,
It is hardly affected by the pressure of the gas emitted from the gas burners 3a and 3b. Therefore, as shown by the two-dot chain line 8a in FIG. 2, the ascent continues toward the vicinity of the end of the net 5 (area A).

The air flowing from the intermediate air inlet 7b is also warmed and rises. The air flowing from the air inlet 7b rises while being pushed by the pressure of the gas discharged from the upper gas burner 3a. . Therefore, as shown by the two-dot chain line 8b in FIG. 2, the net 5 rises toward the vicinity (region B) between the end and the center of the net 5. Further, the air flowing in from the lowermost air inlet 7c is also warmed and rises, but the air flowing in from the air inlet 7c is pushed by the gas pressure of the lower gas burner 3b and the upper gas burner 3a. While rising. Therefore, as shown by a two-dot chain line 8c in FIG.

As described above, the air inlets 7a to 7c
Are arranged vertically above and below the gas burners 3a, 3b,
The air flowing in from each of the air inlets 7a to 7c can be raised at different positions. Therefore,
If the opening area of each of the air inlets 7a to 7c is determined as appropriate at the design stage, the amount of air flowing in and rising therefrom can be adjusted, and the temperature distribution on the net 5 can be adjusted arbitrarily. For example, if an appropriate amount of air is raised in the areas A and B on the net 5, the temperature near the end of the net 5 is lowered as shown in FIG. Obtainable. And if a uniform temperature distribution is obtained,
It is also possible to prevent unevenness in grilling of the food 4 such as meat and fish placed on the net 5.

The above embodiment is only an example, and meat and fish are mentioned as the food material 4. However, the type is not limited at all. Further, the shapes of the gas burners 3a and 3b and the air inlets 7a to 7c are not limited at all. The number of the air inlets 7a to 7c may be at least two or more. That is, even when there is only one gas burner, the gas burners need only be arranged vertically above and below the gas burner.

Furthermore, as in the above embodiment, the air inlets do not have to be arranged vertically with one gas burner interposed therebetween. In other words, although not specifically shown, if necessary, they may be arranged in the order of air inlet → gas burner → gas burner → air inlet.
In other words, the two air inlets may be arranged vertically above and below a plurality of gas burners. Of course, if there are a plurality of gas burners, as in this embodiment, it is possible to raise the air at many different positions by arranging the air inlets vertically above and below each gas burner. Then, if the air is raised at many different positions, the temperature distribution on the net 5 can be finely adjusted.

In the above embodiment, the air is raised not only in the vicinity of the center of the net 5 but also in the vicinity of the end. The temperature distribution is adjusted. Therefore, as shown by the solid line in FIG. 4, the amount of heat may be slightly reduced as a whole. Therefore, warm air may be positively flowed into the air inlets 7a to 7c instead of flowing normal temperature air by natural convection.

For example, although not specifically shown, the side wall 1
Is provided on the outer surface of each of them with the air inlets 7a to 7c as openings. Then, the air heated by a heater or the like may be sent into the chamber by a fan or the like, and may be introduced from the air inlets 7a to 7c. Thus, the air inlet 7a
4 through 7c, it is possible to raise only the entire temperature while keeping the temperature distribution on the net 5 as shown by the dashed line in FIG. Can be.

In the above embodiment, each air inlet 7a
Although the opening areas of 7c to 7c are fixed in advance at the design stage, the opening areas may be freely adjusted. For example, if sliding doors are provided in the air inlets 7a to 7c, the opening area can be adjusted by opening and closing the sliding doors. Thus, the air inlets 7a to 7
If the opening area of 7c is made adjustable, the temperature distribution on the net 5 can be freely adjusted according to the food material 4 and the like even during cooking.

For example, it is usually desired to make the temperature distribution on the net 5 uniform so as to eliminate uneven grilling. However, as shown in FIG. 3, only when a fish is grilled, its head and tail fins ( There is a case where it is desired to burn the area A) without burning and to burn only the body part (the areas B and C). In this case, if the opening area of the uppermost air inlet 7a is relatively large or the opening areas of the air inlets 7b and 7c are relatively small, the air rising toward the vicinity of the end of the net 5 can be obtained. The amount increases. Therefore, only the temperature near the end of the net 5 can be reduced as compared with the other portions, and the fish can be cooked in the desired baking method.

[0020]

According to the present invention, the air flowing from the air inlet above the gas burner is relatively close to the wall, and the air flowing from the air inlet below the gas burner is blown by the gas burner. While being pushed by the gas pressure of the jet gas. Thus, the air flowing in from each air inlet can be raised at a different position. Therefore,
If the opening area of each air inlet is appropriately determined, the amount of air flowing in from there and rising can be adjusted, and the temperature distribution for baking food can be adjusted arbitrarily. For example, if the temperature distribution for baking ingredients is made uniform,
It is possible to prevent uneven baking of the ingredients.

According to the second aspect of the invention, by adjusting the opening area of the air inflow port, the temperature distribution can be freely adjusted according to the food material and the like even during cooking. According to the third aspect, it is possible to raise only the entire temperature without changing the temperature distribution.
