DETAILED DESCRIPTION OF THE INVENTION
With specific reference now to the figures in detail, it is stressed that the particular shown are by way of example and for purpose of illustrative discussion of the preferred embodiments of the present invention only. They are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. The description together with the drawings should make it apparent for those skilled in the art of how several forms of the invention may be embodied in practice.
A portable stove according to the present invention is as indicated in FIGS. 1 and 2 typically comprised of stove main body that includes a burner head 2 provided at substantially the center of the stove main body, a drip pan 1 having a central hole through which the burner head 2 is exposed, and a fuel canister holding compartment 12 provided at one end of the stove main body.
As seen from FIG. 2 in which the drip pan 1 is removed, a heat panel 3 made of metal and in substantially a rectangular shape is provided so as to traverse the stove main body from the burner head 2 so that one end thereof 3a is in contact with the burner head (see FIG. 3) and another end thereof 3b, curved into a letter U, extends into the fuel canister holding compartment 12 (see FIG. 4).
A fuel canister 5 is placed into the fuel canister holding compartment 12 so that it is set on the U-shaped end portion of the heat panel 3 and inserted into the governor 4. Gas is then discharged into the governor 4 and through the fuel supply path (not shown) from the governor 4 to the burner 6. At the burner the fuel is ignited and continuously maintained.
The heat panel 3 is provided such that the flame from the burner head 2 is able to continuously warm the entirety of the heat panel 3. As the entire heat panel 3 warms, the end of the heat panel 3 closest to the fuel canister 5 cradles and warms the fuel canister 5, so that gas inside the fuel canister 5 is heated and reduction of gas pressure is prevented.
FIG. 3 illustrates the manner of attaching the heat panel 3 to the main body of the stove. The heat panel 3 is attached to the stove main body by a screw 7, and rivets 8, and 9.
As seen from FIGS. 5 and 6, the heat panel is not limited to only one embodiment but various modifications thereof may be made. As shown in FIG. 5, one end 3a of the heat panel 3 can be positioned underneath the burner head 2 (and not in touch with the burner head 2) so as to be sufficiently close to the burner head 2 so that heat is transmitted from the burner head 2 to the heat panel 3; and as seen from FIG. 6, the curved end 3b of the heat panel 3 that is inside the fuel canister holding compartment 12 may have a substantial area so as to provide higher thermal conduction to the fuel canister.
Further, various changes in form and detail, such as the shape, thickness and length of the heat panel, the number and shape of the attaching screws and connecting rivets, the construction and type of burner head, and the mode of attachment of the heat panel to the burner head, may be made without departing from the scope of the invention.
