US 2011/0094491 A1 · PETROLEUM STOVE

Abstract

The present invention relates to a petroleum stove, more specifically to a recombustion device which prevents imperfect combustion after ignition and before normal combustion and burns combustion gas effectively, thereby enabling favorable heating. The present invention comprises: a stove body (20) in which a fixed core (23) is inserted in a core pipe (22), an oil supply controller (35) which is installed on the other side of a support (10) and connected to the core pipe (22) through a fuel supply pipe (36) supplying fuel from a fuel tank (37), and a recombustion unit (40) which is installed on top of a support cover (29) and includes a heat radiation unit (41) in which a recombustion chamber (42) is installed. The recombustion chamber comprises: an inner recombustion chamber (43a) which is formed in a cup shape, and an outer recombustion chamber (43b) which is formed in the shape of a cylinder with a wide top and narrow bottom with a bottom diameter less than the diameter of an outer combustion chamber (25b). The top of the outer recombustion chamber is closed with a cover (44) while the bottom is secured on the upper side of the support cover (29). The inner recombustion chamber is inserted in the outer recombustion chamber (43b) and the upper part thereof is fixed to the cover (44). Through holes (45a, 45b) with a diameter of 6-8 mm are formed on the inner and outer recombustion chambers (43a)(43b) at intervals of 0.5-1.5 mm.

An oil stove comprising:

a base;
a stove body in which a wick tube with a fixed wick therein is disposed at a side of the base, a burning tank is disposed on the wick tube, and a protective cover and a support cover are disposed around and on the burning tank, respectively;
an oil controller disposed at the other side of the base, connected to the wick tube by a fuel supply tube, and receiving fuel from a fuel tank;
and
a re-burning unit disposed above the support cover,
wherein the re-burning unit includes a re-burning tank in a heat dissipation assembly, the re-burning tank is composed of an outer re-burning tank having a lower portion smaller in diameter than the diameter of the outer burning tank, formed in a cylindrical shape with the upper portion narrower than the lower portion, with the upper end closed by a cover and the lower end fixed to the top of the support cover, and an inner re-burning tank formed in a cup shape and inserted in the outer re-burning tank, with the upper end fixed to the cover, and
through-holes are formed through the inner and outer re-burning tanks to have a diameter of 6 to 8 mm such that the vertical and horizontal distances between the through-holes are 0.5 to 1.5 mm.
