Referring to the drawings and initially to FIGS. 1-5, a stove body for a large-scale barbecue stove in accordance with the preferred embodiment of the present invention comprises a bottom plate 10, and a cover plate 20 combined with the bottom plate 10.

The bottom plate 10 has a bottom provided with a plurality of equally distant gas supply pipes 30, 32 and 34, and a plurality of ignition devices 40 and 45 mounted between the gas supply pipes 30, 32 and 34. The bottom plate 10 has an inside formed with a plurality of recessed fire supply zones 11, 13 and 16 each connected to a respective one of the gas supply pipes 30, 32 and 34 and each having a peripheral wall formed with a plurality of equally distant vent holes 110, 130 and 160. Preferably, the fire supply zones 11, 13 and 16 of the bottom plate 10 have connections without providing the vent holes 110, 130 and 160. Each of the fire supply zones 11, 13 and 16 of the bottom plate 10 has an inside formed with at least one endless opened lug 111, 131 and 161 extending upward therefrom and having a peripheral wall formed with a plurality of equally distant air holes 112, 132 and 162. Each of the fire supply zones 11, 13 and 16 of the bottom plate 10 has a central portion formed with connecting hole 113, 133 and 163 for mounting a respective one of the gas supply pipes 30, 32 and 34.

The cover plate 20 has an inside formed with a plurality of recessed protrusions 21, 23 and 26 each mounted on a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 and each formed with an endless opening 22, 24 and 27 aligning with the lug 111, 131 and 161 of a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10.

In such a manner, the stove body is formed with at least one independent fire supply zone, so that the volume of each independent fire supply zone is reduced relatively, thereby enhancing the working efficiency (the BTU value) and stability of the fire of each independent fire supply zone, and thereby preventing the stove body from producing gas explosion due to a back fire. In addition, each independent fire supply zone is ignited easily and conveniently, thereby facilitating a user operating the stove body. Further, each independent fire supply zone is operated individually, thereby saving the gas consumption.

The bottom plate 10 is further provided with a plurality of baffles 12, 14 and 17 each mounted between a respective one of the fire supply zones 11, 13 and 16 and the respective lug 111, 131 and 161 to separate the vent holes 110, 130 and 160 of a respective one of the fire supply zones 11, 13 and 16 from the air holes 112, 132 and 162 of the respective lug 111, 131 and 161 so as to accelerate the gas flow, thereby stabilizing the gas pressure, distributing the flame length and maintaining stability of the fire.

The bottom of the bottom plate 10 has a side provided with a fire connection box 18 located opposite to the ignition devices 40 and 45 and connected to each of the fire supply zones 11, 13 and 16 to interconnect the fire supply zones 11, 13 and 16. Each of the ignition devices 40 and 45 is mounted on the bottom plate 10 by a respective fixing bracket 41. The bottom of the bottom plate 10 is provided with two opposite support racks 19 to secure the stove body on a frame of the barbecue stove.

As shown in FIGS. 5 and 6, the bottom plate 10 has a peripheral wall formed with a flange 100 protruding outward therefrom, and the cover plate 20 has a peripheral wall formed with a bent enclosure 200 extending inward therefrom and enclosed around the flange 100 of the bottom plate 10, so that the cover plate 20 is combined with the bottom plate 10 rigidly and stably, thereby producing an air tight effect.

The stove body further comprises a plurality of annular fixing members 31, 33 and 35 each mounted between a respective one of the gas supply pipes 30, 32 and 34 and the connecting hole 113, 133 and 163 of a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 to fix each of the gas supply pipes 30, 32 and 34 on a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10.

In addition, each of the gas supply pipes 30, 32 and 34 has an end provided with an arc-shaped catch plate 300, 320 and 340 protruding from the connecting hole 113, 133 and 163 of a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 and facing the air holes 112, 132 and 162 of the respective lug 111, 131 and 161 of a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 so as to form an air circulation effect, so that the gas from each of the gas supply pipes 30, 32 and 34 will be filled with a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 rapidly and will not flow outward from the air holes 112, 132 and 162 of the respective lug 111, 131 and 161 of a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 immediately.

When in use, when the ignition devices 40 and 45 are started, each of the gas supply pipes 30, 32 and 34 supplies gas into a respective one of the fire supply zones 11, 13 and 16 of the bottom plate 10 simultaneously. In such a manner, the stove body is formed with a plurality of independent fire supply zones, thereby largely reducing the volume for filing the gas, so that the gas is ignited easily and conveniently, thereby facilitating a user igniting the stove body. In addition, each of the baffles is mounted between a respective one of the fire supply zones and the respective lug to separate the vent holes of a respective one of the fire supply zones from the air holes of the respective lug so as to accelerate the gas flow in each of the fire supply zones, thereby stabilizing the gas pressure, distributing the flame length and maintaining stability of the fire.

Accordingly, the stove body is formed with at least one independent fire supply zone, so that the volume of each independent fire supply zone is reduced relatively, thereby enhancing the working efficiency (the BTU value) and stability of the fire of each independent fire supply zone, and thereby preventing the stove body from producing gas explosion due to a back fire. In addition, each independent fire supply zone is ignited easily and conveniently, thereby facilitating a user operating the stove body, and thereby increasing the lifetime of each of the ignition devices. Further, each independent fire supply zone is operated individually, thereby saving the gas consumption. Further, the stove body is formed with a plurality of independent fire supply zones, thereby largely reducing the volume for filing the gas, so that the gas is ignited easily and conveniently, thereby facilitating a user igniting the stove body. Further, each of the baffles is mounted between a respective one of the fire supply zones and the respective lug to separate the vent holes of a respective one of the fire supply zones from the air holes of the respective lug so as to accelerate the gas flow in each of the fire supply zones, thereby stabilizing the gas pressure, distributing the flame length and maintaining stability of the fire. Further, each of the gas supply pipes has an end provided with an arc-shaped catch plate to form an air circulation effect, so that the gas from each of the gas supply pipes will be filled with a respective one of the fire supply zones of the bottom plate rapidly and will not flow outward from the air holes of the respective lug of a respective one of the fire supply zones of the bottom plate immediately.
