6
CA 02483948 2004-10-06
1 supply zones 11, 13 and 16. Each of the ignition devices 40 and 45 is
mounted
2 on the bottom plate 10 by a respective fixing bracket 41. The bottom of the
3 bottom plate 10 is provided with two opposite support racks 19 to secure the
4 stove body on a frame of the barbecue stove.
As shown in Figs. 5 and 6, the bottom plate 10 has a peripheral wall
6 formed with a flange 100 protruding outward therefrom, and the cover plate
20
7 has a peripheral wall formed with a bent enclosure 200 extending inward
8 therefrom and enclosed around the flange 100 of the bottom plate 10, so that
.
9 the cover plate 20 is combined with the bottom plate 10 rigidly and stably,
thereby producing an air tight effect.
11 The stove body further comprises a plurality of annular fixing
12 members 31, 33 and 35 each mounted between a respective one of the gas
13 supply pipes 30, 32 and 34 and the connecting hole 113, 133 and 163 of a

21 of the respective lug 111, 131 and 161 of a respective one of the fire
supply
22 zones 11, 13 and 16 of the bottom plate 10 so as to form an air circulation
effect,
7
CA 02483948 2004-10-06
1 so that the gas from each of the gas supply pipes 30, 32 and 34 will be
filled
2 with a respective one of the fire supply zones 11, 13 and 16 of the bottom
plate
3 10 rapidly and will not flow outward from the air holes 112, 132 and 162 of

4 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.
6 When in use, when the ignition devices 40 and 45 are started, each of
7 the gas supply pipes 30, 32 and 34 supplies gas into a respective one of the
fire
8 supply zones 11, 13 and 16 of the bottom plate 10 simultaneously. In such a
9 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
11 ignited easily and conveniently, thereby facilitating a user igniting the
stove
12 body. In addition, each of the baffles is mounted between a respective one
of
13 the fire supply zones and the respective lug to separate the vent holes of
a
14 respective one of the fire supply zones from the air holes of the

16 stabilizing the gas pressure, distributing the flame length and maintaining
17 stability of the fire.
18 Accordingly, the stove body is formed with at least one independent
19 fire supply zone, so that the volume of each independent fire supply zone
is
reduced relatively, thereby enhancing the working efficiency (the BTU value)
21 and stability of the fire of each independent fire supply zone, and thereby
22 preventing the stove body from producing gas explosion due to a back fire.
In
8
CA 02483948 2011-08-26
1 addition, each independent fire supply zone is ignited easily and
conveniently,
2 thereby facilitating a user operating the stove body, and thereby increasing
the
3 lifetime of each of the ignition devices. Further, each independent fire
supply
4 zone is operated individually, thereby saving the gas consumption. Further,
the
stove body is formed with a plurality of independent fire supply zones,
thereby
6 largely reducing the volume for filing the gas, so that the gas is ignited
easily
7 and conveniently, thereby facilitating a user igniting the stove body.
Further,
8 each of the baffles is mounted between a respective one of the fire supply
9 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
11 the gas flow in each of the fire supply zones, thereby stabilizing the gas
12 pressure, distributing the flame length and maintaining stability of the
fire.
13 Further, each of the gas supply pipes has an end provided with an arc-
shaped
14 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
