Description  |

BACKGROUND OF THE INVENTION
The present invention is to provide a charcoal stove casing set which is
adapted for preparation of barbecue or for cooking out during outdoor
camping or other outdoor activities and which is also very practical for
household fireplace application.
Regular portable baking stoves are normally designed to use charcoal as a
fuel to make a fire for roasting meat or for cooking. Therefore, it is
very inconvenient to carry packages of black charcoals while cooking out,
for which some participants may be unable to fully enjoy the outdoor
activities.
Although regular charcoal is a combustible round rod, it is still very
difficult to burn. To initially build a fire, it is more practical to
knock a charcoal to pieces. While knocking a charcoal to pieces, waste
charcoal chips may result from the process. While burning, the heavy smoke
from the fire may irritate the throat, nose or eyes of the fire builder,
who may unconsciously inhale harmful substances. Further, during roasting
process, the grease dropped from either chicken meat or pork or other meat
may drastically strengthen the intensity of the fire to burn the roast or
the user may even suffer from a burn on the hand.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a charcoal stove
casing set, wherein a charcoal mixture is incorporated with a presspaper
casing and is firmly secured in the presspaper casing by means of a fixing
strap integrally extended from one side of said presspaper casing so as to
let the whole assembly be convenient to carry.
Another object of the present invention is to provide a charcoal stove
casing set wherein a solid alcohol contained in an alcohol trough is
fixedly set in the presspaper made casing, and a match stick is
horizontally disposed on said solid alcohol and covered with two
phosphorated boards to facilitate striking a fire.
A yet further object of the present invention is to provide a charcoal
stove casing set wherein the charcoal mixture is made of charcoal chips,
wood flour and black earth, which does not produce heavy smoke or burn the
roast while burning.
Further objects, features and other aspects of this invention will be
understood from the following detailed description of preferred
embodiments of this invention with reference to the annexed drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 through 2, a charcoal stove casing set constructed in
accordance with the present invention is shown. A charcoal stove casing
set is comprised of a presspaper made frame body (1), a solid alcohol
trough (2), and charcoal mixture (3). The presspaper made frame body (1)
is a paper casing (1), having a tearing line (11) made on the bottom edge
at each end, a phosphorated strip (12) made on the end surface above a
tearing line (11), and a fixing strap (13) integrally extended from one
side. The fixing strap (13) comprises a ring-shaped portion (131) at the
center. The solid alcohol trough (2) is fixedly set in said presspaper
made frame body (1). The charcoal mixture (3) comprises a vent hole (31)
on the top at the center, surrounded by a plurality of vent holes (32),
and said charcoal mixture also comprises a groove (33) at the bottom for
receiving said solid alcohol trough (2). When said charcoal mixture (3) is
set in said paper casing (1) to contain said solid alcohol trough (2) in
said groove (33), said fixing strap (13) is turned to secure to the other
side of the paper casing (1) to secure said charcoal mixture (3) in said
paper casing (1) as shown in FIG. 1.
Referring to FIG. 3, said alcohol trough (2) is a concavely frame body
(222) of which the inner wall (21) of the extended side boards is covered
with phosphorated material. There is provided a solid alcohol (221)
wrapped with an aluminum foil (22). A match stick (23) is disposed on said
solid alcohol (221) and also wrapped by said aluminum foil (22). When said
solid alcohol (221) is set in said alcohol trough (2), the head (231) of
said match stick (23) is horizontally disposed on the extended board and
covered by said phosphorated inner wall (21) with the front end of said
head of said match stick (23) slightly protruding beyond said phosphorated
inner wall (21) to provide wider friction area so as to conveniently help
strike the match stick (23).
Referring to FIGS. 4 through 5, said two tearing lines (11) disposed at
both ends of said paper casing (1) are downwardly pressed to open to let
said match stick (23) protrude therebeyond. When said match stick (23) is
manually dragged up by force, the friction force resulted from said head
(231) of said match stick (23) against said phosphorated inner wall (21)
will build up a fire to burn said solid alcohol (221) and said paper
casing (1) so as to further burn said charcoal mixture (3) slowly. Because
said charcoal mixture (3) comprises a plurality of vent holes (31) and
(32), when said two tearing lines (11) are opened, said vent holes (31)
and (32) are disposed to communicate with the atmosphere through said
groove (33) to facilitate circulation of air through said charcoal mixture
(3) so as to help burning. In case a fire is not created when said match
stick (23) is dragged up, one may strike the head of said match stick (23)
against said phosphorated strip (12) and throw the burning match stick
into said vent hole (31) to burn said solid alcohol (221). When said match
stick (23) is initially pulled out of said alcohol trough, said aluminum
foil (22) is caused to open or to tear out. Therefore, if a burning match
stick is thrown into said vent hole (31) said solid alcohol (221) is
disposed for burning.
In the present invention, said charcoal mixture (3) is shape-formed through
compressed pressure and most preferably consists of 65% charcoal chips by
weight, 20% wood flour by weight, and 15% black earth by weight. Through
said arrangement, the charcoal mixture is very practical to build a mild
fire without producing heavy smoke.
In general, the present invention is to provide such a charcoal stove
casing set which uses solid alcohol to practically burn a charcoal
mixture, wherein said charcoal mixture comprises vent holes and bottom
groove to help air circulation, and wherein said charcoal mixture is
composed of charcoal chips, wood flour and black earth in a reasonable
proportion, having numerous features each of which tends to make the
mixture more practical to use without causing air pollution and more
inexpensive to manufacture.
