11, 13 and 16 of the bottom plate 10.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
