[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a double-sided grill that can simultaneously heat cooked food such as fish placed on a grill net from both the top and bottom.

[0002]

[Prior Art]

 In this type of double-sided grill, for example, as disclosed in Japanese Patent Laid-Open No. 3-210217, a grill net is provided at an intermediate portion in the vertical direction inside the heating cabinet main body, and cooked foods are provided on both sides of the lower portion of the heating cabinet main body. There is a Bunsen-type lower-burning burner that heats the cookware from the lower side, and a surface-burning-type upper-burner burner that heats the cooked food from the upper side by heat radiation in the opening formed in the top plate of the heating cabinet body. As pointed out in the above publication, in this type of double-sided grill, heating under the cooked product by the lower-fire burner tends to be insufficient near the center. It is provided in the openings formed on both sides of the lower part of the heating cabinet body, and the combustion heat is transferred to the central part by the force of the secondary air flowing from this.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technology, in order to transport the combustion heat to the vicinity of the central portion and eliminate the lack of heating near the lower center of the cooked product, it is necessary to increase the distance between the bottom of the heating cabinet and the grill net to some extent or more. There is. For this reason, there is a problem that the distance between the grill net and the top heat burner is inevitably small, and it is not possible to cook a large thick cooked product. If the distance on the upper side of the grill net is increased in order to enable the cooking of a large cooked product, the height of the entire double-sided grill becomes large, making it difficult to match the height with other cooking utensils. The present invention aims to solve such a problem.

[0004]

[Means for Solving the Problems]

 To this end, the double-sided grill according to the present invention includes a heating cabinet 10 and a grill net 15 provided at an intermediate portion in the vertical direction in the heating cabinet 10 as shown in FIGS. A lower fire burner 20 provided on both sides of the lower part of the heating cabinet body 10 to heat the cooking product F placed on the grill net 15 from below, and the cooking product provided on the upper part of the heating cabinet body 10. In a double-sided grill comprising an upper fire burner 25 for heating F from the upper side, the lower fire burner is provided in the lower center of the grill net 15 in the heating cabinet main body 10 along the symmetry plane of the lower fire burners 20. A heating plate 18 to be heated is provided.

[0005]

[Operation and effect of the device]

 Bottom fire burners provided on both lower sides of the heating cabinet body heat the cooked food on the grill net from both lower sides, and heat the heating plate in the lower center of the grill net by radiant heat. The heated heating plate generates a hot gas flow that rises toward the center of the grill net by convection, which heats the lower center of the cooked product. In this way, since the lower central part of the cooked food, which is insufficiently heated directly from the lower fire burners on both sides, is heated by the hot gas flow from the heating plate, the distance between the bottom of the heating cabinet and the grill net is reduced. However, the heating of the lower central part of the cooked product will not be insufficient. This makes it possible to increase the distance between the grill net and the upper fire burner without increasing the overall height of the double-sided grill, and to cook a large and thick cooked product on the grill net. You can

【Example】

 1 and 2 show a first embodiment of a double-sided grill according to the present invention. A pair of supporting metal fittings 16 fixed to the vertical middle portions of the inner surfaces of the left and right side plates 10a of the rectangular box-shaped heating cabinet body 10 has a grill net 15 placed on the front side in the drawing so that the grill net 15 can be taken out. The inside of the heating cabinet body 10 is divided into two chambers, an upper chamber and a lower chamber, by 15. At the bottom of each side plate 10a, an elongated lower opening 11 whose edge is bent inward is formed along the horizontal front-back direction, and an upper opening 12 is formed at the top plate 10b.

A lower fire burner 20 is provided on each side plate 10 a of the heating cabinet body 10 corresponding to each lower opening 11, and an upper fire burner 25 is provided on the top plate 10 b. A heating plate 18 is provided vertically in the lower center of the grill net 15 in the heating cabinet body 10 along the symmetry planes of the left and right lower fire burners 20. Although not shown in the drawings, a grill net 15 and an opening for loading and unloading cooked foods are formed on the front side of the heating cabinet body 10 and can be opened and closed by a door having a hinge on the lower side. A saucer 17 is put on the bottom plate 10c of the heating cabinet main body 10 so that water can be put into it during cooking and also serves as a juice receiver.

The lower heat burner 20 is of a Bunsen type, and has a cylindrical burner main body 21 provided in parallel with each lower opening 11, and a lower burner main body 21 protruding from the burner main body 21 and passing through the lower opening 11 inside the heating cabinet main body 10. "It is composed of a large number of flame holes 22 extending obliquely downward. Fuel gas supplied into the burner body 21 by mixing primary air from a gas supply pipe (not shown) provided with a gas valve is jetted from the flame holes 22 into the heating cabinet body 10 and ignited. It mixes with the secondary air taken in through the lower opening 11 and burns.

The upper fire burner 25 is of a surface combustion type, and has a box-shaped burner body 26 provided corresponding to the upper opening 12 of the top plate 10b, and an upper portion provided on the entire lower opening of the burner body 26. The flame hole forming plate 27 projects from the opening 12 into the heating cabinet body 10. The flame hole forming plate 27 is made of a ceramic material and has innumerable small holes extending from the surface on the burner body 26 side toward the free surface inside the heating cabinet body 10. The fuel gas, in which all the air required for combustion is mixed as primary air, is supplied into the burner main body 26 from a gas supply pipe (not shown) provided with a gas valve, and the small size of the flame hole forming plate 27 is supplied. It is ejected from the holes and ignited, and it burns in the vicinity of the free surface of the flame hole forming plate 27 and red heats the vicinity of this free surface.

As shown mainly in FIG. 2, the heating plate 18 of the present embodiment is a flat plate shape, and the legs at both ends are fixed to the bottom plate of the pan 17 by welding or the like and rise vertically. The heating plate 18 is coated with a black heat resistant paint so as to easily absorb radiant heat.

During cooking, the free surface of the flame hole forming plate 27 of the upper flame burner 25 is red-heated, and the heat radiation from this heats the upper side of the cooked product F. The lower heat burner 20 directly heats the cooked food F on the grill net 15 and heats the heating plate 18 in the lower center of the heating cabinet body 10 mainly by radiant heat. The heated heating plate 18 heats the air in contact therewith to generate a hot gas flow rising toward the central portion of the grill net 15, whereby the lower central portion of the cooked food F is heated.

When the distance between the bottom plate 10c of the heating cabinet main body 10 and the grill net 15 is small, the heating of the lower central portion of the cooked product F tends to be insufficient only by the direct heating by the lower heat burner 20. Since the lower central part is heated by the hot gas flow rising from the heating plate 18, even if the distance between the bottom plate 10c of the heating cabinet body 18 and the grill net 15 is small, the lower central part of the cooked food F is heated. Will never run out. As a result, the distance between the grill net 15 and the upper fire burner 25 can be increased without increasing the overall height of the double-sided grill, and a large and thick cooked product F can be placed on the grill net 15. It can be placed and cooked.

The second embodiment shown in FIGS. 3 and 4 is that the lower flame burner 20 is a surface burning type burner instead of the Bunsen type, and the heating plate 18 having a Λ cross section is supported by the grill net 15. It is only different from the one embodiment. Each lower flame burner 20 of the second embodiment is composed of a burner body 23 and a flame hole forming plate 24, and is provided in a lower opening 11a formed in the lower portion of each side plate 10a. This lower fire burner 20 has substantially the same structure as the upper fire burner 25 of the first embodiment, and the fuel gas in which all the air necessary for combustion is mixed as the primary air is supplied to the burner main body 23 to cause the flame. Combustion occurs near the free surface of the hole forming plate 27, and red heat is generated near the free surface.

As shown mainly in FIG. 4, the grill net 15 of the second embodiment is composed of a main body 15a formed by combining rods by welding and a pair of support legs 15b welded to the front and rear of the main body 15a. The front and rear ends of a heating plate 18 in which a plate material is bent in a Λ cross section shape are welded and fixed to each support leg 15b. In the grill net 15, a main body 15a on which the cooked food F is placed is supported by a support leg 15b on the bottom plate 10c, and the main body 15a is supported at an intermediate portion in the vertical direction inside the heating cabinet body 10, and the heating plate 18 is inside the heating cabinet body 10. It is located in the lower center of the grill net 15 along the symmetry plane of the left and right lower fire burners 20. The tray 17 is placed between the support legs 15b, and the support fitting 16 of the first embodiment is unnecessary.

The operation of the upper burner 25 during cooking is exactly the same as in the first embodiment. The lower heat burner 20 directly heats the cooked food F on the grill net 15 mainly by radiant heat, and at the same time, heats the heating plate 18 in the lower center of the heating cabinet body 10. As in the first embodiment, this causes a hot gas flow to rise toward the central portion of the grill net 15, and the lower central portion of the cooked food F 1 is heated. Since other structures and operations are similar to those of the first embodiment shown in FIGS. 1 and 2, corresponding parts are designated by the same reference numerals, and detailed description thereof will be omitted.

In the second embodiment, the lower-burner burner 20 and the upper-burner burner 25 are both surface combustion type burners, and the respective burner bodies 23 and 26 are provided with primary air for all the air required for combustion. Fuel gas mixed as gas is supplied. Therefore, it is also possible to connect the upper and lower burners 20, 25 with a gas duct and supply the fuel gas mixed with the primary air through a common gas supply pipe provided with a common gas valve. Since the piping to the burners 20 and 25 is simplified and the number of gas valves is reduced, the manufacturing cost can be reduced.

Although the upper fire burner 25 is attached to the top plate 10b of the heating cabinet body 10 in each of the above embodiments, the upper fire burner is divided into right and left like the lower fire burner 20 of the second embodiment. You may make it provide in the upper part of the side plate 10a.
