Description

  The present invention relates to an oil combustor.

Conventionally, in this type, the wind from the front of the oil combustor flows downward from the upper part of the combustion cylinder, and the air from the lower part of the front of the oil combustor flows upward from the lower part of the combustion cylinder. These two wind flows cancel out the influence of the wind from the front of the oil combustor, and the flame is normally located in the combustion cylinder, which burns more than the air flowing downward from the upper part of the combustion cylinder Since the air flowing upward from the bottom of the cylinder is weaker, for example, a wind-resistant plate is provided at the bottom of the combustion cylinder, thereby pushing up the air from the bottom of the combustion cylinder to the combustion cylinder and canceling the influence of the upper and lower wind flow It was.
(For example, see Patent Document 1)

  By the way, in this conventional one, in order to further suppress the generation of unburned gas in the combustion cylinder, if the combustion cylinder is made higher and the secondary cylinder is formed by the upper part of the inner cylinder and the combustion ring, The opening of the cylinder is large and more air flows downward from the upper part of the combustion cylinder, and only the windproof plate does not have enough air to flow upward from the lower part of the combustion cylinder. I sometimes got out of flame.

  In addition, in this conventional system, a combustion section having a combustion cylinder and a cartridge-type fuel tank are incorporated in the main body of the oil combustor. The position of the combustion cylinder is displaced, for example, when the cartridge type fuel tank is stored on the right side with respect to the front of the main body, the position of the combustion cylinder is shifted to the left with respect to the center of the main body. The wind from the angle did not flow sufficiently to the bottom of the combustion cylinder, and the flame was pushed down to the core guide pipe.

Therefore, the applicant previously filed an oil combustor in which a wind collecting plate is provided at the bottom of the core cylinder and a wind direction plate is provided at a position in front of the wind collecting plate.

  By the way, in this conventional one, when oblique wind blows from the side where the combustion cylinder is displaced with respect to the front of the oil combustor, the air flowing into the bottom of the core cylinder under the combustion cylinder is not deficient. The wind collides with the wind direction plate and guides it to the air collecting plate, so that sufficient air is supplied from the lower part of the core cylinder toward the upper part, and the air from above the combustion cylinder is lower than the air from the upper part of the combustion cylinder. Although the air was reduced and the flame of the combustion core was prevented from being pushed down, the cartridge-type fuel tank inserted into the oil combustor was made large so that the height of the oil combustor body was increased and the oil As a result of changing the size and shape of the pedestal so that the combustor is more difficult to tip over, the front vent at the lower front of the oil combustor has become smaller, so the air from above the combustion cylinder increases and the air from below the combustion cylinder Less Flame wick was intended to become depressed for.

  The present invention focuses on this point and solves the above-mentioned problems. In particular, in the first aspect of the present invention, a main body frame constituted by a front plate having an open front upper part and a front lower part freely removable, and the main body frame is attached. Placed on the stand, a cartridge-type oil tank placed on the top and oiled from the cartridge-type oil tank, and supplied with oil from the oil tank and burned A combustion section, the combustion section includes a core inner cylinder erected in the combustion section, a core outer cylinder that includes the core inner cylinder and in which a combustion core is disposed in a gap between the core inner cylinder, Provided at the upper part of the core inner cylinder and the core outer cylinder, the center is provided with a combustion cylinder provided at a position shifted from the center of the oil combustor body, and a front vent is formed between the front plate and the table. A vent is formed from the front vent to the bottom of the core in the core. In the oil combustor, air flowing from the front vent to the vent is formed by the step formed at both ends of the stand and the stand rectifying plate provided so that both ends are in contact with the upper surface of both steps. A ventilation guide portion for guiding is formed.

  Further, in the oil combustor according to claim 2, in particular, in the structure according to claim 1, the pedestal rectifying plate is long from the center of the combustion cylinder to the center of the oil combustor main body and is long with respect to the front vent. A wind direction plate is provided so that the directions are parallel.

  Further, in the oil combustor according to claim 3, in particular, in the structure according to claim 2, a wind collecting plate is provided at the bottom of the core inner cylinder, and the wind collecting plate is a cylinder inserted into the bottom of the core inner cylinder. And a guide piece that is formed at the bottom of the insertion portion and guides the air flowing from the ventilation portion formed between the bottom portion of the core inner cylinder and the mounting table to the core inner cylinder bottom portion. And a wind collecting portion that is formed long to the left and right with respect to the bottom portion.

  According to the first aspect of the present invention, air flowing in from the front vent is ventilated by the step portions formed at both ends of the stand and the stand rectifying plate provided so that both ends are in contact with the upper surfaces of both step portions. Since the air flow guide part that guides to the part is formed, all the air that flows in from the front air vent passes through the air flow guide part and flows into the air vent part, so even if the front air vent is smaller than before, A lot of air can be supplied to the combustion cylinder by raising the internal space from the lower part to the upper part of the core cylinder, and even if the height of the oil combustor body is increased and the air from the upper part of the combustion cylinder increases, Air flowing into the combustion cylinder from the upper front of the oil combustor, and from the front vent of the lower front of the oil combustor, rising from the lower part of the core inner cylinder toward the upper part, and supplied to the combustion cylinder Air can be balanced and normal combustion can be done Than is.

  According to a second aspect of the present invention, in the first aspect of the present invention, the pedestal rectifying plate has a front vent located at a position from the center of the combustion cylinder to the center of the main body of the oil combustor. Since the wind direction plate is provided so that the longitudinal direction is parallel to the center, the wind direction plate is provided at a position from the center of the combustion cylinder to the center of the oil combustor body, so that combustion is performed with respect to the front of the oil combustor. It has the same effect as widening the front vent for the wind blown diagonally from the side where the cylinder is displaced, and if there is no wind direction plate, it does not flow to the bottom of the cylinder in the core and around the lower part of the oil combustor. A large amount of slanting air from the left flowing from outside the oil combustor through a hole or the like collides with the wind direction plate and guides it to the bottom of the core cylinder, and a strong wind slanting from the left with respect to the front of the oil combustor. Even if it is blown in, the air flowing into the combustion cylinder from the top of the front of the oil combustor and oil combustion The air that flows in from the front vent at the lower front and rises from the lower part to the upper part of the core cylinder and balances the air supplied to the combustion cylinder so that normal combustion can be performed. .

  Also, since the wind direction plate is provided so that the longitudinal direction is parallel to the front vent, more air is blown obliquely from the side where the combustion cylinder is displaced relative to the front of the oil combustor. Can be guided to the bottom of the cylinder, and the influence of obstructing the flow of air blown from the side opposite to the side where the combustion cylinder is displaced relative to the front of the oil combustor to the bottom of the core cylinder can be reduced. Is.

  According to a third aspect of the present invention, there is provided the oil combustor according to the second aspect, wherein the air collecting plate is provided at the bottom of the core inner cylinder, and the air collecting plate is provided at the bottom of the core inner cylinder. A cylindrical insertion portion inserted into the insertion portion, and a guide piece that is formed at a lower portion of the insertion portion and guides air flowing from the ventilation portion formed between the bottom portion of the core inner tube and the mounting base to the core inner tube bottom portion. Since the air collecting part is formed to be long to the left and right with respect to the bottom of the core inner cylinder, the air collecting plate is prevented from coming off by inserting the insertion part into the core inner cylinder bottom and fixing the air collecting plate. In addition, since the guide pieces of the air collecting portion of the air collecting plate are formed long in the left and right directions, more air can be guided to the core cylinder.

Next, an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a main body frame having an open front upper portion, which is constituted by a front plate 2 which is detachable at the lower front portion. In the center of the front plate 2, the combustion core 3 moves up and down by rotating, The core up / down knob 4 that performs the ignition operation by rotating to the ignition position and holding the position, and the seismic automatic fire extinguishing device (not shown) is operated by pushing into the upper part of the core up / down knob 4 to instantaneously A fire extinguishing button 5 is provided to extinguish the fire by lowering the lead to the fire extinguishing position.

  Reference numeral 6 denotes a table on which the main body frame 1 is attached. On the table 6, a cartridge type oil tank 7 is placed on the upper side, and an oil tank unit 8 is supplied with oil from the cartridge type oil tank 7. A combustion section 9 that is supplied with oil and combusts is disposed.

  10 is a core inner cylinder erected in the combustion section 9, 11 is a core outer cylinder containing the core inner cylinder 10, and the combustion core 3 is disposed in a gap with the core inner cylinder 10, 12 is a core inner cylinder 10, and When the upper end of the combustion core 3 is protruded from the combustion cylinder 12 by the upper and lower knobs 4 and ignited by the combustion cylinder provided on the upper part of the core outer cylinder 11, the combustion air rises in the inner space of the inner cylinder 10 and the combustion cylinder. The fuel in the oil tank portion 8 supplied to the combustion core 12 and sucked up by the combustion core 3 starts to burn in the combustion cylinder 12.

  13 is a wind collecting plate, which is formed between a cylindrical insertion portion 14 to be inserted into the bottom portion of the core inner cylinder 10 and a lower portion of the insertion portion 14, and is formed between the bottom portion of the core inner cylinder 10 and the mounting table 6. A wind collecting portion 17 formed by extending a guide piece 16 for guiding the air flowing in from the vent portion 15 to the bottom of the core tube 10 to the left and right with respect to the bottom of the core tube 10. The air which flows in from the front vent 18 formed horizontally between the two and flows through the vent 15 is guided to the bottom of the core tube 10.

  Accordingly, by inserting the insertion portion 14 into the bottom of the core inner cylinder 10 and fixing the air collecting plate 13, the air collecting plate 13 is prevented from coming off, and the guide piece 16 of the air collecting portion 17 is formed long in the left and right directions. As a result, more air can be guided to the inner core tube 10.

  Reference numeral 19 denotes a flat plate baffle plate, and a wind direction plate 20 is provided at a position slightly from the center of the combustion cylinder 12 with respect to the front vent 18 at a position slightly from the center of the main body frame 1, By being provided in contact with the convex step portions 21 formed at both end portions of the mounting table 6, a ventilation guide portion 22 that is a closed space for guiding the air flowing in from the front vent 18 to the ventilation portion 15 is formed. To do.

Next, the operation of this embodiment will be described.
When the lead up / down knob 4 is rotated to the ignition position and held in that position, the combustion lead 3 rises to the ignition position, and the combustion lead 3 that has sucked up the fuel in the oil tank 8 is moved by an ignition device (not shown). Ignite.

  Normally, the air flowing into the combustion cylinder 12 from the upper part in front of the oil combustor and the front vent 18 in the lower part of the front of the oil combustor, passing through the ventilation guide part 22 and from the lower part to the upper part of the core cylinder 10. The air that is raised toward the internal space toward the combustion cylinder 12 is balanced, and normal combustion is performed.

  At this time, a part of the air flowing in from the front vent 18 has flowed upward in the oil combustor without going to the vent 15 in the past, but in the present invention, the air flowing in from the front vent 18 All flow through the ventilation guide portion 22 and flow into the ventilation portion 15, so even if the front vent 18 is smaller than the conventional one, more air than in the conventional case is transferred from the lower portion to the upper portion of the inner core tube 10. Since the space can be raised and supplied to the combustion cylinder 12, even if the height of the oil combustor body is increased and the air from above the combustion cylinder increases, it flows into the combustion cylinder 12 from the upper part in front of the oil combustor. The air and the air supplied from the front vent 18 at the front lower part of the oil combustor and rising from the lower part to the upper part of the core inner cylinder 10 to be supplied to the combustion cylinder 12 are balanced. Combustion takes place.

  In this normal combustion state, when wind blows obliquely into the front of the oil combustor, the oblique wind from the right side with respect to the front of the oil combustor is the center of the combustion cylinder 12 (BB line in FIG. 1). Is shifted to the left with respect to the center of the oil combustor (the line AA in FIG. 1), the oblique wind from the right side of the center of the combustion cylinder 12 has a wide front vent 18 and Since the air collecting plate 13 is positioned at the tip of the blown air, sufficient air is supplied from the lower part of the core inner cylinder 10 toward the upper part.

  Conversely, the oblique wind from the left side with respect to the front of the oil combustor is directed to the center of the combustion cylinder 12, and the oblique wind from the left side is narrower at the front vent 18 and is further blown from the oblique side. Since the air collecting plate 13 is not positioned, sufficient air is not supplied from the lower part of the core cylinder 10 to the upper part as it is, and as it is, more air flows into the combustion cylinder 12 from the upper part in front of the oil combustor. As a result, the flame will be pushed down.

  Therefore, by providing the wind direction plate 20 on the pedestal rectifying plate 19 in front of the air collection plate 13, the oblique wind from the left side with respect to the front of the oil combustor collides with the wind direction plate 20 and collects the wind. Since the front vent 18 is narrow because it is guided by the plate 13 and the air collecting plate 13 is not located beyond the front air inlet 18, sufficient air is supplied from the lower part to the upper part of the core inner cylinder 10. Is.

   Further, by arranging the wind direction plate 20 in front of the air collecting plate 13, even if a foreign object enters from the front vent 18, the wind direction plate 20 does not come into contact with the foreign object and the foreign material does not enter the air collecting plate 13. Thereby, the inflow port of the air at the bottom of the core inner cylinder 10 can always be secured to prevent the occurrence of incomplete combustion.

  Further, the wind direction plate 20 is provided at a position closer to the center of the oil combustor than the center of the combustion cylinder 12, so that the front vent 18 for the oblique wind from the left side is widened. If there is no wind direction plate 20, more oblique air from the left side that flows out of the oil combustor through the holes around the lower part of the oil combustor without flowing to the air collection plate 13 collides with the wind direction plate 20. Even if strong wind obliquely blown from the left side with respect to the front of the oil combustor is guided to the air collecting plate 13, the air flowing into the combustion cylinder 12 from the upper front of the oil combustor and the front of the lower front of the oil combustor The air that flows in from the air vent 18 and rises from the lower part to the upper part of the core inner cylinder 10 and balances the air supplied to the combustion cylinder 12 so that normal combustion is performed.
