Description

  The present invention relates to an oil stove and, more particularly, to a reburning device for a fixed core type oil stove.

  As is well known, the core type oil stove is divided into a core fixing type and a core lifting type, and the core fixing type has a simpler structure than the core lifting type and can be produced and supplied at a low cost. Have.

  One of the inventors of the present invention has been producing and selling a fixed core type oil stove for many years to meet the above requirements, and a typical model is patented under the name fixed core type stove with a flow controller attached. It is disclosed in Document 1.

  The fixed core stove with the flow controller is provided with a support column; a core tube is installed on one side of the support column, a fixed core is inserted, and an air supply hole (diameter 1.7 mm) is formed above the core tube. ) Are formed at predetermined intervals, a combustion cylinder is formed, a support cover is installed on the upper surface of the combustion cylinder, and a protective cover is installed around the combustion cylinder. A stove body in which recombustion air supply holes are respectively formed in the upper part of the cylinder; a refueling regulator installed on the other side of the substrate and connected to the core pipe by a fuel supply pipe, and fuel is supplied from a fuel tank; A heat dissipating member main body having a diameter larger than that of the external combustion cylinder and formed with a through hole is installed in the support cover, and a chimney-attached cover is installed at the upper end thereof, and a plurality of through holes are formed inside the heat dissipating member main body. A heat sink with a circumferential heating element installed; and , Hole formed in the radiator body forming the diameter 4mm and out.

  The fixed core stove equipped with the flow controller adjusts the fuel supply controller to supply fuel at a predetermined flow surface to the fixed core inserted into the core tube. When the fixed core is ignited, the fuel is evaporated. When the evaporative gas is burned in a red-hot state by the primary air supplied from the air supply hole between the inner and outer combustion cylinders and rises to the radiator, it is formed on the upper end of the protective cover and the outer combustion cylinder, respectively. After being re-combusted by the circumferential heating element by the air supplied to the combustion air supply hole, the heat is radiated from the side surface of the radiator body and discharged from the chimney.

Patent Document 1: CN1755196 (A)

  However, the fixed core stove equipped with the flow controller adjusts the core tube by igniting after filling the core tube with fuel of a predetermined flow surface. When the lower part of the combustion cylinder is heated, the fuel filled in the core pipe is evaporated at the same time to generate a large amount of evaporative gas. Until the evaporation of the fuel filled in is completed (hereinafter referred to as “initial ignition”), incomplete combustion occurs, and as described above, if incomplete combustion occurs in the initial ignition stage, odors and soot are generated.

  On the other hand, as described above, the incomplete combustion gas generated at the beginning of ignition and the combustion gas normally burned (this combustion gas is not completely burned) rises to the radiator and is reburned.

Therefore, the incomplete combustion gas and the combustion gas are dispersed and raised inside the radiator body, and the recombustion atmosphere of the incomplete combustion gas cannot be formed well inside the radiator body. Reburning is good because the inside of the body does not reach the reburning temperature In addition, if the recombustion of incomplete combustion gas or the like is not good as described above, the heat dissipating body and the circumferential heat generating body cannot be in a red hot state, and the heat radiation amount is small, which is good and comfortable. There is a problem that is difficult to heat.

In the third embodiment, the outer reburning cylinder 43b is formed in a cylindrical shape, with the cylinder 43b being formed in a cylindrical shape with a narrow upper part and a wide lower part.

  In the first to third embodiments, the bottom surface of the internal recombustion cylinder 43a is formed in an arc shape, and the combustion gas burned in the combustion cylinder 24 is recombusted between the internal recombustion cylinder 43a and the external recombustion cylinder 43b. Better combustion by raising smoothly (flexible) and quickly when rising to the chamber.

  In the present invention as described above, after the stove is digested, the fuel supply adjuster 25 is adjusted to fill the core tube 22 with fuel at a predetermined flow surface, and then the fixed core 23 is ignited. The evaporated gas is burned in the combustion chamber between the internal combustion cylinder 25a and the external combustion cylinder 25b by the primary air supplied to the perforated plate 31 and the air supply hole 32, and then the upper end of the external combustion cylinder 25b. The air is mixed with the air supplied to the air supply hole 27 formed on the support cover 29 and is gathered while being guided by the combustion gas guide plate 30 formed on the support cover 29, between the internal recombustion cylinder 43 a and the external recombustion cylinder 43 b. Is recombusted by the air supplied to the heat radiation holes 48 formed in the heat radiator 41.

  After the combustion gas (radiant heat) recombusted as described above is exhausted from the through hole 45b formed in the external recombustion cylinder 43b, a part thereof is horizontally exhausted from the heat dissipation hole 48 formed in the radiator 41, The remaining part receives the resistance of the baffle 47 and is discharged from the heat radiating hole 48, and the radiant heat not discharged from the heat radiating hole 48 bypasses the baffle 47 and is discharged by the chimney 46 to heat the room.

  As described above, the combustion gas primarily burned in the internal combustion cylinder 25a and the external combustion cylinder 25b rises while gathering in the recombustion chamber formed between the internal recombustion cylinder 43a and the external recombustion cylinder 43b. The re-burning atmosphere is formed by maintaining a high temperature state, and the through holes 45a and 45b formed in the internal re-combustion cylinder 43a and the external re-combustion cylinder 43b are formed to have a diameter of 6 to 8 mm. By forming the distance between the upper and lower left and right sides of the holes 45a and 45b to be 0.5 to 1.5 mm, the contact surface area is smaller than the amount of combustion gas to be recombusted, so the internal recombustion cylinder 43a and the external recombustion The cylinder 43b is heated to a red hot state and burned completely, thereby eliminating the generation of odors and soot.

  Even if a large amount of evaporative gas is generated at the beginning of ignition, the interval between the recombustion chambers formed between the internal recombustion cylinder 43a and the external recombustion cylinder 43b is formed such that the lower part is larger than the upper part, 43a and the external recombustion cylinder 43b gradually decrease in volume from the bottom to the top, so that the combustion gas burned in the combustion cylinder 24 rises between the internal recombustion cylinder 43a and the external recombustion cylinder 43b. By increasing the hourly flow velocity while increasing, the combustion gas disappears, and by maintaining a high temperature atmosphere well, complete combustion can be performed even at the initial stage of ignition.

In fact, the present inventors have created a reburning means 40 having a specific structure as described above, and tested the prototype by comparing about 10 comparative products with different original and reburning methods. As a result, it was proved that the present invention can achieve the best reburning.
