Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to eliminate uneven grilling on the bottom surface of a grill such as double-sided grilling.

The lower burner of a double-sided grill is required to uniformly grill the lower surface of the object to be heated, to prevent clogging caused by dripping liquid, to cause poor combustion, and to generate as little smoke as possible. There are particularly strong demands on the latter two, and the key is to satisfy these demands and to what extent the unevenness of grilling can be eliminated to produce delicious grilled food. For this purpose, the conventional method of storing the tototsu (-) in the inner side wall of the grill chamber as shown in Fig. 1 and blowing out only the heel flame has been adopted.In this way, dripping of liquid into the flame hole is prevented. In addition, the latter two of the three problems mentioned above are satisfied because there is no high-temperature area where dripping liquid drips and smokes.However, since a heating cup is formed on the inside wall of the refrigerator, it is difficult to distribute the heat on the bottom surface of the object to be heated. One of the measures conventionally considered is shown in Fig. 1.The flame chamber for heating the lower surface of the object to be heated, which is formed in the burner a, is guided toward the center of the refrigerator by the hot air diffuser C and collected. By spreading, it spreads over the entire wire section (heated object) to make the heat distribution uniform.However, in reality, the difference in height between the burner and the heated object is less than 40 to 5 own, making it uniform. It is said that it is more beautiful and tastier to fry it upside down.

In the present invention, by changing the shape of the lower flame, the flow of hot air is dispersed between the central part and the peripheral part of the refrigerator, and the heat is made uniform, and will be explained in conjunction with experimental results. Figure 2,
FIG. 3 shows an embodiment of the present invention. 1 is the grill body, which is incorporated into a gas staple or the like. A grill burner 5 is installed inside the main body 1 and forms an upward flame 2 and inward flames 3 and 4 on both sides of the lower part. The upward flame 2 heats a radiator 8 surrounded by an outer wall 6 and an inner wall 7 and formed at the upper end of the outer wall. Reference numeral 9 denotes a grill grate which is secured to the internal wall 7 and on which the object to be heated 11 is placed in the grill interior 1o. 12 is a saucer for liquid containing water.

Here, the aim of the present invention is to form the inward flames 3 and 4, and in the example shown in FIG. 3, the areas of the flame holes 13 and 14 are changed every other flame hole. That is, the large flame hole 13 forms a long flame 3 and heat reaches the center of the refrigerator, while the small flame hole 1
4, a short small flame 4 is formed to disperse heat around the inside of the refrigerator. The effect of elongating the flame 3 during cooking is that heat reaches the center of the chamber, and the elongation rapidly promotes the diffusion of the hot air flow downstream from the leading edge of the flame. Experiments have shown that even if the pitch of the flame holes is such that the flame transfer between the flame holes is not smooth, uneven burning will occur in the center of the chamber.
A heat distribution that does not cause the JL problem has been obtained. This means that the heat from below cannot provide a large amount of heat as only the surface burns, so the long flame is placed at sufficient intervals (
It can be placed with a temperature of 10 to 20 degrees (depending on the internal dimensions of the refrigerator), and can provide a substantially even heat distribution around the center of the refrigerator with the same amount of heat as before. However, forming a long flame will conversely result in insufficient heat flow in the periphery, and the pitch between the flame holes 13 will be large. Incidentally, these flame hole area ratio, pitch, etc. should be determined experimentally based on the internal conditions of the refrigerator.

The function as a grill is similar to the conventional function, and the aim of the present invention has been described above.

FIG. 4 shows another embodiment, in which a plurality of flame expansion plates 15 attached to the burner 6 are disposed so as to come into contact with the flame at every interval, and the flame is expanded 4' in the horizontal direction, so that the flame holes 13 The aim is to equalize the heat distribution between the center and periphery of the refrigerator without changing the area of the refrigerator. However, the flame hole pitch needs to be determined experimentally.

As described above, the present invention attempts to equalize the heating distribution from the bottom surface by appropriately changing the shape of the flame, and achieves the effect with simple means by utilizing the difference in the diffusion of hot air flow depending on the flame length and ejection speed. 1, which is something
