[0003]

[Problems to be solved by the device]

 However, in such a gas grill 6, since the upper flame burners 25 are provided on both sides of the upper portion of the heating cabinet main body 10, the radiant heat generated from the upper flame burner 25 and reaching the cooked foods A 1, B, C is at both ends. The cooked food B in the center is weaker than the cooked foods A and C because it is farther from the upper heat burner 25. That is, the cooked foods A, B, C evenly placed on the grill net 15 have different adjustment performances depending on the places where they are placed, and the cooked foods A, C at both ends close to the upper burner 25 are It was said that the cooked food B in the central portion, which was farther from the upper heat burner 25, burned quickly, although it burned quickly. Further, when the thickness of the cooked food A, B, C is large, it takes time for the radiant heat generated from the top burner 25 to penetrate into the cooked food A, B, C, and the cooked food A, B There was also the problem of uneven baking, where the surface of C was well baked but the inside was not yet baked. In addition, not only the radiant heat generated by the upper flame burner 25 but also the combustion exhaust of the upper flame burner 25 and the lower flame burner 20 rises due to convection particularly on the upper surface of the heating cabinet body 10 (hereinafter referred to as the top plate 10b). However, due to the heat transfer caused by the direct contact with the top plate 10b, the temperature is likely to rise and there is a fear of overheating. The gas grill of the present invention solves the above-mentioned problems and enables any of the cooked foods A, B, C to be cooked uniformly, and also the cooked foods A, B, C having a large thickness. The purpose is to allow heat to penetrate well into the interior so that the interior can be cooked sufficiently evenly. It is also an object to lower the temperature of the top plate 10b of the heating cabinet body 10 to prevent its overheating.

【Example】

 In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the gas grill of the present invention will be described below. FIG. 1 shows a schematic configuration of a gas grill 1 as a first embodiment. A pair of support metal fittings 16 fixed to the upper and lower intermediate portions of the inner surfaces of the left and right side plates 10a of the square box-shaped heating cabinet main body 10 is provided with a grill net 15 which can be taken out to the front side in the figure. Due to this, the inside of the heating cabinet body 10 is divided into an upper chamber and a lower chamber. It should be noted that the grill net 15 is provided with legs extending downward, and instead of the supporting metal fittings 16, this leg is placed on the bottom plate 10c of the heating cabinet body 10 so that the grill net 15 is placed in the heating cabinet body 10 in the vertical direction. You may make it support in an intermediate part. On the grill net 15, cooked foods A, B, C such as fish are placed side by side in the horizontal direction and heated and cooked by the heat of the burner.

A surface combustion type upper fire burner 25 is provided in an upper opening 12 formed in an upper portion of each side plate 10a. Similarly, a surface combustion type lower fire burner 20 is provided in the lower opening 11 formed in the lower portion of each side plate 10a. A radiation plate 13 is provided at the center inside the top plate 10b, which is the upper surface of the heating cabinet body 10. Further, on the bottom plate 10c of the heating cabinet main body 10, there is provided a saucer 17 which can be taken out and serves as a soup holder for receiving water during cooking. Although not shown in the drawings, the grill net 15 and the openings for putting in and out the cooking products A, B, C formed on the front side of the heating cabinet body 10 have doors having hinges on the upper side or the lower side. It can be opened and closed by a door provided integrally with the tray 17.

The surface combustion type upper flame burner 25 and the lower flame burner 20 provided on both upper and lower sides of the heating cabinet body 10 are burner bodies 26, 23 provided along the side plates 10a and the burner bodies 26, 23, respectively. Each flame mouth forming plate 27, 24 is provided in the entire opening on the main body 26, 23 side and protrudes from the upper opening 12 and the lower opening 11 into the heating cabinet main body 10. Each flame port forming plate 27, 24 is made of a ceramic material and has innumerable small holes extending from the surface on the side of each burner body 26, 23 to the free surface inside the heating chamber body 10. Although not shown, the fuel gas is supplied from the gas supply pipe provided with a gas valve into each burner body 26, 23 by mixing all the air required for combustion as primary air, and is supplied to each flame port forming plate 27, 24. It burns near the free surface and glows red near this free surface. The upper side of the cooked foods A, B, C is heated mainly by the heat radiation from the free surface of the red-heated upper flame mouth forming plate 27. The lower side of the cooked foods A, B, C is heated by the heat radiation from the free surface of the lower flame mouth forming plate 24 which is also red-heated, and in addition, the lower fire burner 20 ejects the same. It is also heated by the convection of the high temperature combustion gas. Of course, since the grill net 15 has a mesh-like shape, the radiant heat from the flame port forming plate 24 is transmitted to the cooking products A, B, C, and the combustion gas is also convected upward to directly cook the cooking product A. , B, C by contacting and transferring heat.

As described above, the upper side of the cooked foods A, B, C is mainly heated by the radiant heat of the flame mouth forming plate 27, but the inner side of the central portion of the top plate 10b above the heating cabinet body 10 is radiated. Since the plate 13 is provided, the radiant heat from the flame port forming plate 27 directly reaches the cooked products A, B, C and that which reaches the cooked products A, B, C after being reflected by the radiant plate 13. There is. Therefore, even in the case of the cooked food B placed at the center of the grill net 15 and separated from the flame mouth forming plate 27, the radiant heat reflected from the radiating plate 13 directly reaches from the flame mouth forming plate 27. Since it compensates for the weakening, the radiant heat is sufficiently applied as in the case of the cooked foods A and C on both ends close to the flame mouth forming plate 27, and cooking can be performed in a well-balanced manner.

A gas grill 2 using a far infrared radiation plate 14 instead of the above radiation plate 13 will be described as a second embodiment. This is one in which the far-infrared radiation plate 14 is replaced at the same position on the radiation plate 13, and the other construction is exactly the same as that of the first embodiment, and a detailed description of the overlapping portions will be omitted. The far-infrared radiation plate 14 is a plate surface made of metal or the like coated with a far-infrared radiation material, and emits far-infrared radiation when the temperature rises. In this example, a composition comprising an oxide such as manganese dioxide, cobalt oxide, copper oxide or chromium oxide and an inorganic compound such as a low melting point high expansion glass (for example, lead-free borosilicate glass) was used. The film is made by sintering. The far-infrared radiation plate 14 transmits the radiant heat from the flame port forming plate 27 and the convection of the combustion exhaust gas from the upper burner 25 and the lower burner 20 in the same manner as described with reference to FIG. 1 in the first embodiment. The temperature rises in response to heat. The far-infrared radiation plate 14 absorbs the heat steadily, and when the temperature becomes high, the far-infrared radiation material works to efficiently radiate far-infrared radiation. That is, the far-infrared radiation plate 14 converts the heat energy absorbed in various states (specifically, radiant heat composed of heat transfer and electromagnetic waves having a wide range of wavelengths) into electromagnetic waves of a specific wavelength (far-infrared rays). It serves to release it.

As is well known, far infrared rays are generally known as infrared rays (electromagnetic waves having a wavelength of approximately 0.8 μm to 1 mm) having a long wavelength. Far infrared rays are used to mean a region of 5 μm or more. Far-infrared rays have better absorption in foods and the like than electromagnetic waves with short wavelengths in other regions (for example, visible rays and ultraviolet rays). In other words, it has the advantage of being absorbed moderately by a substance and being efficiently converted into heat energy without causing a chemical change in the substance. Taking advantage of this advantage, far-infrared rays have been widely used for a long time as a wisdom of life for stone-baked sweet potatoes, sweet chestnuts, etc. using far-infrared rays generated from burnt stones.

The far-infrared radiation plate 14 in the second gas grill 2 also uses this, and the upper sides of the preparations A, B, and C are mainly radiant heat from the flame port forming plate 27 and high-temperature radiation. It is heated by far infrared rays from the infrared radiation plate 14. Further, as in the case of the first gas grill 1, the radiant heat from the flame port forming plate 27 directly reaches the cooked foods A, B, and C, and is once absorbed by the far-infrared radiating plate 14 and then becomes far-infrared again. Some are changed and radiated, and some reach cooked items A, B, and C. Therefore, even in the case of the cooked food B placed at the center of the grill net 15 and separated from the flame mouth forming plate 27, the far infrared rays emitted from the far infrared ray emitting plate 14 directly reach from the flame mouth forming plate 27. Since the radiant heat is compensated for weakening, sufficient heat is applied to the cooking products A and C on both ends near the flame mouth forming plate 27, and cooking can be performed with good balance. In addition to this, in the gas grill 2, as described above, the far-infrared rays are properly absorbed by the cooked foods A, B, and C, and the heat is efficiently transferred. You can enjoy delicious cooking without even unevenness, even if the inside is well-cooked.

Next, as a third embodiment, for example, as shown in FIG. 2, a description will be given of a gas grill 3 in which the above-mentioned radiation plate 13 is provided inside the central portion of the top plate 10b above the heating cabinet body 10 at a predetermined distance H. To do. This is one in which a distance H from the radiation plate 13 and the top plate 10b is separated, and other configurations are exactly the same as those in the first embodiment, and corresponding parts are designated by the same reference numerals and overlapping parts are shown. The detailed description of is omitted. As described above, the radiant plate 13 receives the radiant heat from the flame port forming plate 27 and the heat transfer by the convection of the combustion exhaust of the upper flame burner 25 and the lower flame burner 20. Then, the radiant plate 13 reflects most of the radiant heat but absorbs part of the radiant heat, and the heat transfer described above is also added to increase the temperature. Since this gas grill 3 is provided with the radiation plate 13 at a distance H from the top plate 10b, air enters between the top plate 10b and the radiation plate 13 and the air has a heat insulating effect, so that the high temperature The heat of the radiant plate 13 that has become the heat is hard to be transmitted to the top plate 10b, and the top plate 10b is prevented from overheating. In this way, the gas grill 3 prevents the top plate 10b from overheating simply by providing the radiation plate 13 that enhances the cooking effect, at a distance H from the top plate 10b. Therefore, it is not necessary to install any special parts that enhance heat insulation, and there is a cost reduction effect by reducing the number of parts.

Next, as a fourth embodiment, a description will be given of a gas grill 4 in which the heating cabinet main body is not provided with a lower-flame burner and has only the upper-fire burner. Unlike the gas grills 1, 2 and 3 described so far, the gas grill 4 is not provided with a lower fire burner, as shown in FIG. 3, and the cooking products A 1, B and C on the grill net 15 are It is heated only by the upper fire burner 25 provided on both side surfaces 40a of the heating cabinet body 40. Even in the gas grill 4 having such a configuration, by providing the radiation plate 13 or the far-infrared radiation plate 14 at the center inside the top plate 40b, the same action and effect as the gas grills 1, 2 and 3 described above can be obtained. .

Finally, as a fifth embodiment, a gas grill 5 having different types of lower fire burners will be described. As shown in FIG. 4, for example, the gas grill 5 is provided with a surface combustion type burner 25 above both side surfaces 50a of the heating cabinet main body 50 and a Bunsen type burner 30 below both side surfaces 50a. Further, similarly to the gas grills 1, 2, 3, 4 of the above-described embodiment, the radiation plate 13 or the far-infrared radiation plate 14 is provided inside the central portion of the top plate 50b above the heating cabinet main body 50. . The Bunsen-type burner 30 has a large number of flame openings 32 extending slightly obliquely downward in the heating cabinet body 50 from the projecting openings 31 on the side surface 50a of the heating cabinet body. Then, from the flame port 32, the fuel gas supplied from the gas supply pipe (not shown) and the primary air from the air intake port (not shown) are mixed, and the mixed gas is ejected into the heating chamber main body 50. To do. At that time, the secondary air is sucked from the protruding opening 31, and the mixed gas is ignited to form a flame. Since the Bunsen type burner 30 hardly generates radiant heat, the lower side of the cooking products A, B and C on the grill net 15 is burned by the heat generated by the convection of the combustion exhaust gas of the Bunsen type burner 30. On the other hand, the upper side of the cooked food A, B, C is heated by the surface burner 25, so that the radiation performance of the radiation plate 13 or the far-infrared radiation plate 14 improves the cooking performance in the same manner as described above. And it can be cooked quickly. Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the scope of the present invention.
