ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a BBQ grill, and more particularly to a grill with self ignition capability.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a conventional BBQ grill has a post
10
seating on a base
50
and supporting a furnace
20
at its top end. The bottom portion of the furnace
20
extends a lip
21
. The outer diameter of the lip
21
is smaller than the inner diameter of the post
10
. The base
30
also extends a lip
31
which its outer
10
diameter is also smaller than the inner diameter of the post
10
.
To assemble, the lip
21
of the furnace
20
is sleeved into the top end of the post
10
and is screwed tight by screws
22
. The lip
31
of the base
30
is sleeved into the bottom end of the post
10
and is screwed tight by screws
32
as well. This embodiment has the following shortcomings:
1. it requires at least four screws
22
and
32
to bind the post
10
, the furnace
20
and the base
30
together which needs more cost and is not stable;
2. the product has no auxiliary ignition device;
3. both of the furnace
20
and the post
30
have to form separate lips
21
and
31
which increase the cost.
SUMMARY OF THE INVENTION
It is the primary object of the present invention to provide a BBQ grill with ignition system which is easy to assemble and disassemble.
It is another object of the present invention to provide a BBQ grill with ignition system which enables to self-ignite the charcoal.
It is a further object of the present invention to provide a BBQ grill with ignition system which design is simple and requires less manpower to install.
