Description

  The present invention relates to a mounting structure of equipment parts for obtaining a heater having a fireplace atmosphere.

  A general pressure spray type oil combustion heater has a bottomed cylindrical burner, and a wind tunnel is attached to the burner so as to cover the entire circumference of the burner, and the wind tunnel burns through a wind guide member. Connected to the blower. A nozzle for spraying fuel is installed on the side of the burner, and an electromagnetic pump for pressurizing the fuel is connected to the nozzle via an oil feed pipe. Further, an ignition electrode is disposed in front of the burner nozzle, and an ignition transformer for generating a high voltage is connected to the ignition electrode.

  In addition, a combustion chamber whose outer wall is configured by a transparent heat ray transmitting portion is disposed at the upper portion of the burner, and a red-hot member that is red-hot by combustion heat is disposed inside the combustion chamber (see Patent Document 1).

  When the ignition operation is performed, the combustion blower starts operation, and the generated wind is sent to the wind tunnel via the air guide member and supplied to the burner. At the same time, an ignition transformer connected to the ignition electrode is energized, and a discharge spark is generated from the ignition electrode by the high voltage generated by the ignition transformer. Next, when the electromagnetic pump is operated, fuel pressurized to high pressure is supplied to the nozzle, so that mist-like fuel is sprayed from the nozzle into the burner, and at this time, a discharge spark is generated from the ignition electrode. Therefore, the high-pressure atomized fuel blown from the nozzle is ignited by this spark and starts to burn.

  If the combustion of the burner is started and the ignition operation is completed and the combustion is stabilized, the combustion continues even if the ignition transformer is turned off and the discharge from the ignition electrode is stopped. Is sent to the burner, and air is sent to the burner by the blower for combustion, whereby combustion continues in the burner.

  If combustion in the burner continues in this way, the high-temperature combustion gas generated as a result of combustion rises from the burner and is sent into the combustion chamber. The high-temperature combustion gas heats the red-hot member installed in the combustion chamber, and the infrared rays and far-infrared heat rays generated from the red-hot member that has become hot at a high temperature pass through the heat ray transmitting portion formed on the combustion chamber wall. It is discharged to the surroundings and used for heating.

  On the other hand, if energization of the electromagnetic pump is stopped to stop the operation of the heater, the electromagnetic pump stops and stops sending fuel into the burner, and the fuel remaining in the burner burns out and burner Since the fire extinguishes, the power supply to the combustion blower is stopped and the supply of combustion air to the burner is stopped.

  In the above-described heater, the size of the combustion chamber in which the red hot member is disposed needs to be a size that enables stable combustion with the maximum heat generation amount of the burner, so the size of the combustion chamber can be arbitrarily changed. Is not possible. In addition, in order to make the red hot member arranged in the combustion chamber well red hot, the high temperature combustion gas is filled in the combustion chamber, and the red hot member to be red hot is arranged in the high temperature combustion gas to raise the red hot member to a high temperature. However, in order for this red hot member to become hot, not only the heat capacity balance of the red hot member and the shape of the member but also the size of the combustion chamber are greatly affected. Even if it was possible, if the calorific value changed, it was difficult to sufficiently heat the red-hot member.

  For this reason, in the heater which combines the conventional red-hot member in the combustion chamber and also serves as heat-wire heating, the size of the combustion chamber cannot be arbitrarily changed. When the amount of combustion is reduced, only the lower part of the red-hot member is red-heated and the whole is darkened.At the maximum combustion amount, the high-temperature part of the combustion gas is located outside the red-hot member. As a result, the red fever deteriorated.

The present invention relates to a specific structure for making the red-hot member sufficiently red hot regardless of the size of the combustion chamber. A combustion chamber 2 that is heated by the combustion heat of the burner 1 is disposed above the burner 1, In the heating machine in which the heat ray transmitting part 3 is formed on at least a part of the wall of the combustion chamber 2 and the red hot member 4 is provided in the combustion chamber 2, the combustion chamber 2 facing the heat ray transmitting part 3 is disposed in the combustion chamber 2. A red-hot member holding body 5 formed of a plurality of wires 5a is provided, and a space A continuous with the upper part of the burner 1 is formed in the combustion chamber 2 in a dome shape by the red-hot member holding body 5. The member 4 is composed of a pseudo coal piece 6 resembling a coal block piece by a ceramic foam. The pseudo coal piece 6 is provided with a through hole 6a in advance, and the through hole 6a is inserted into the wire 5a and adjacent to the pseudo coal. A gap 7 between the piece 6 Attached to the glowing member holder 5 while form, the combustion gas generated in the burner 1 is retained in the space A is covered with the red-hot member 4, wherein the combustion gas filled in the space A pseudo coal pieces 6 is diffused into the combustion chamber 2 through the gap 7 between the two, and the pseudo coal piece 6 is red-heated by high-temperature combustion gas.

The through hole 6a of the pseudo coal pieces 6 that is attached to the glowing member holder 5 is inserted into the wire 5a, pseudo coal piece 6 is adapted to be easily mounted while maintaining the high red heat state.

Further, a red heat member holding body 5 formed of a mesh member 5 b is provided in the combustion chamber 2 facing the heat ray transmitting portion 3, and a space A continuous with the immediately upper portion of the burner 1 is provided in the combustion chamber 2. is formed in a dome shape by the glowing member holder 5, the pseudo coal piece 6 is the red-hot member holding member while forming a gap 7 between the pseudo coal pieces 6 adjacent fitted into a mesh of the mesh member 5b pseudo coal pieces 6 by being attached to 5 it has become possible to uniformly attached.

  In the present invention for solving the above-mentioned problem, the pseudo coal piece 6 is arranged in the combustion chamber 2 arranged at the upper part of the burner 1 so that a space A continuous in the burner 1 can be formed. The combustion gas in the space directly under the pseudo coal piece 6 also maintains a high temperature, and this combustion gas passes through the gap 7 between the pseudo coal pieces 6 while heating each pseudo coal piece 6 from the lower part. Since it diffuses in the combustion chamber 2, the pseudo coal piece 6 can be efficiently heated to a red hot state.

  Further, even when the amount of combustion is reduced, the combustion gas filling the space A continuing to the burner 1 cannot immediately flow out into the combustion chamber 2, so that a high temperature can be maintained regardless of the size of the combustion chamber 2. Therefore, the red heat condition of the pseudo coal piece 6 can be separated from the other conditions such as the size and shape of the combustion chamber 2 and the combustion amount of the burner 1, and the size of the red heat member 4 can be separated. The sheath shape can be freely designed.

  Moreover, since the space A is formed in a dome shape while inserting the red-hot member holding body 5 composed of the wire 5a into the through-hole 6a of the pseudo coal piece 6, the pseudo coal piece 6 is located directly above the burner 1. It can be correctly arranged on the outer periphery of the continuous space A, and each pseudo coal piece 6 can be easily fixed at the designed position.

  Further, since the space A in the combustion chamber 2 is formed in a dome shape by the red-hot member holding body 5 formed by the mesh member 5b, the space A continuous with the upper part of the burner 1 is easily formed by the mesh member 5b. In addition, by fitting each piece of pseudo coal piece 6 into the mesh of the mesh member 5b, it is possible to easily and evenly attach it without using the specially processed piece of pseudo coal piece 6. Became.

  Hereinafter, the configuration will be described with reference to the drawings showing examples. In FIG. 1, 1 is a bottomed cylindrical burner for burning petroleum-based fuel, 8 is a wind tunnel arranged so as to cover the entire circumference of the burner 1, and 9 is a combustion for sending combustion air to the burner 1 The blower 10 is a wind guide member that guides combustion air between the wind tunnel 8 and the combustion blower 9. When the combustion blower 9 is operated, the air is sent into the wind tunnel 8 through the wind guide member 10. The air is supplied into the burner 1 from the air hole provided in the side wall of the burner 1.

  11 is a nozzle installed on the side wall of the burner 1, 12 is an electromagnetic pump for sending fuel to the nozzle 11, 13 is an oil feed pipe for connecting the nozzle 11 and the electromagnetic pump 12, and oil not shown when the electromagnetic pump 12 is operated The fuel sent from the tank is pressurized by the electromagnetic pump 12 and can be sprayed into the burner 1 in the form of mist from the tip of the nozzle 11 connected by the oil feed pipe 13.

  14 is an ignition electrode installed on the side surface of the burner 1 so that the tip is located in front of the nozzle 11, and 15 is an ignition transformer that applies a high voltage to the ignition electrode 14, and the heater is ignited. Then, the combustion blower 9 and the ignition transformer 15 are energized, and the combustion blower 9 starts operation and the generated wind is sent to the burner 1 as combustion air. The energized ignition transformer 15 supplies a high voltage to the ignition electrode 14 to generate a discharge spark at the tip of the ignition electrode 14. Thereafter, when the electromagnetic pump 12 is energized, the pressurized fuel is sprayed into the burner 1 across the discharge spark, so that the mist-like fuel is ignited.

  The heating machine of the embodiment shown in FIG. 2 uses a pot type oil combustor as a heat source of the heating machine, and 16 is an ignition heater that is attached to the inside of the burner 1 through the side wall of the bottomed cylindrical burner 1. It is. In this embodiment, when the ignition operation of the heater is performed, the combustion blower 9 and the ignition heater 16 are energized, and the wind of the combustion blower 9 that has started operation is sent to the burner 1 as combustion air. The ignition heater 16 becomes red hot. Next, when the electromagnetic pump 12 is energized, fuel is forcibly sent to the burner 1 and combustion is started by the heat of the ignition heater 16.

  In the heater of the embodiment shown in FIG. 1 and FIG. 2, 17 is an auxiliary combustion member such as a combustion ring disposed in the burner 1, and 2 is a combustion chamber disposed in the upper part of the burner 1. The started fuel creates a mixed gas with the air sent from the wind tunnel 8 by the function of the auxiliary combustion member 17, and a part of the fuel is burned in the burner 1 and the other is burned in the combustion chamber 2 following the burner 1. Do. When combustion is started, stable combustion can be continued as it is even if the ignition transformer 15 and the ignition heater 16 are de-energized. When stopping the operation of the heater, first, the energization of the electromagnetic pump 12 is stopped, the supply of fuel to the burner 1 is stopped, and after the fuel remaining in the burner 1 is burned out, the operation of the combustion blower 9 is started. To stop.

  Further, 3 is a heat ray transmitting portion made of heat-resistant glass or the like over a part or the whole of the wall surface of the combustion chamber 2, 4 is a red heat member arranged inside the combustion chamber 2, and a general red heat member 4 is a porous cylindrical body disposed in the combustion gas, or a pseudo tree as described in the preceding patent document 1 is disposed immediately above the burner 1 and is heated by the combustion gas in the combustion chamber 2. ing. Although such a red-hot member 4 is strongly red-hot at a portion close to the burner 1, the red-hot is bad at the upper part of the red-hot member 4 away from the burner 1, and even if the entire red-hot member 4 can be red hot at the maximum heat generation amount When the amount of combustion was reduced, the entire red hot member 4 was darkened.

  In the embodiment shown in the figure, A is a space configured to be continuous with the inside of the burner 1 inside the combustion chamber 2, and 5 is a red heat member holder for arranging the red heat member 4 inside the combustion chamber 2. The red heat member holder 5 is fixed to the peripheral edge of the burner 1 and rises upward from the peripheral edge of the circular burner 1. Further, the red heat member holder 5 is curved upward toward the burner 1. The space A is formed by covering the upper part of the burner 1.

  6 is a pseudo-coal piece made of ceramic foam to form one lump, and finished in a shape resembling a coal block piece, but the actual coal block itself is not of a specific shape, If it is a lump, it will be considered as a block of coal. The block-like pseudo coal piece 6 is attached to the red hot member holder 5 and is disposed on the outer peripheral edge of the space A, which is the boundary between the space in the combustion chamber 2 and the space A above the burner 1. .

  Reference numeral 7 denotes a gap formed between the adjacent pseudo coal pieces 6 of the pseudo coal pieces 6 attached to the red hot member holder 5, and when the combustion gas generated in the burner 1 diffuses into the space A, the exit of the space A Since only the gap 7 is present, high-temperature combustion gas stays in the space A to increase the internal pressure, and when this high-temperature combustion gas passes through the gap 7 between the pseudo coal pieces 6 into the combustion chamber 2, The pseudo coal piece 6 can be efficiently heated and red-hot.

  A conventional cylindrical red heat member or pseudo-tree-like red heat member arranged on the upper portion of the burner 1 loses red heat at the upper portion of the red heat member 4 when the burner 1 is burned, but it becomes dark. Each of the lump-like pseudo coal pieces 6 has a back surface inserted into the space A, and even when the combustion amount is reduced, the space A is filled with high-temperature combustion gas. The back surface is always exposed to high temperature and is red hot, and the side of the combustion chamber 2 of the pseudo coal piece 6 is also heated from the side by the combustion gas passing through the gap 7, so even when the amount of combustion is reduced The two pseudo coal pieces 6 are red hot and no longer dark. Furthermore, since the other pseudo coal pieces 6 that can be seen through the gap 7 of the pseudo coal piece 6 are always red-hot, the gap 7 portion is strongly red hot even if the red heat degree of the surface of the pseudo coal piece 6 is slightly inferior. It is in a state. For this reason, not only the pseudo coal piece 6 located at the top of the pseudo coal piece 6 is also red hot, but the whole pseudo coal piece 6 that seems to be stacked can be seen red hot, and the amount of combustion changes. It became the optimal arrangement structure of the red hot member 4 of the heating machine.

  FIG. 3 shows an embodiment of the red hot part, and 5a is a wire rod that constitutes the red hot member holding body 5 at both ends attached to the outer peripheral edge of the burner 1 and located at the boundary between the space A and the combustion chamber 2. , 6a are through holes provided in the pseudo coal piece 6, and the pseudo coal piece 6 can be positioned on the outer peripheral edge of the space A by inserting the wire 5a into the through hole 6a of the pseudo coal piece 6. .

  As a specific attachment method, the pseudo coal piece 6 is inserted and attached to the wire 5a that has been formed in advance with the space A using the through hole 6a, and the end of the wire 5a is fixed to the peripheral portion of the burner 1. Thus, the red hot member 4 can be positioned in the combustion chamber 2, thereby forming a dome-shaped space A, so that it does not require a complicated shape when fixing the pseudo coal piece 6 and can be fixed easily. Became. Even if the red-hot pseudo coal piece 6 is attached by the wire 5a, most of the wire 5a is located in the through hole 6a of the pseudo-coal piece 6, so that the heat of the pseudo-coal piece 6 is red hot. It became easy to raise heat resistance.

  Further, since the pseudo coal piece 6 can be disposed at a specified position in the combustion chamber 2 by passing the through hole 6a through the wire 5a, a dome-shaped space A can be easily formed above the burner 1, and a plurality of wires can be formed. Each of 5a holds a plurality of pseudo coal pieces 6 and is arranged in a plane along the outer peripheral edge of the space, so that the pseudo coal pieces 6 which are red heat members can be arranged correctly without being stacked, and the pseudo coal pieces Since a gap 7 communicating with the inside of the space can be formed between the six, it becomes possible to heat the entire plurality of pseudo coal pieces 6 evenly.

  FIG. 4 shows another embodiment of the red hot portion, 5b is a net-like member formed by curving into a dome shape, a relatively large mesh in which the pseudo coal piece 6 is fitted in this net-like member 5b, and combustion It consists of a relatively small mesh for venting gas. The end of the net-like member 5b is attached so as to surround the outer periphery of the burner 1, and the pseudo coal piece 6 is fitted into the larger net of the net-like member 5b so that the pseudo coal piece 6 is placed in the space in the combustion chamber 2. It became possible to hold | maintain on the outer periphery of A.

  Further, when the pseudo coal piece 6 is fitted into the mesh of the mesh member 5b forming the red hot member holder 5, the wire constituting the mesh member 5b is fitted into the mesh while being slightly deformed according to the shape of the pseudo coal piece 6. Therefore, it is possible to easily fix the pseudo coal piece 6 without fixing a complicated structure or special work when the pseudo coal piece 6 is fixed. In addition, the burner is formed by the shape of the mesh member 5b. A dome-shaped space A continuous from 1 could be easily formed.

  Further, the net-like member 5b forming the red-hot member holding body 5 is configured in advance so that the pseudo coal pieces 6 fitted into the net can be easily and uniformly arranged. The piece 6 can be arranged at the boundary between the dome-shaped space A and the combustion chamber 2, and the pseudo coal piece 6 is held on the outer peripheral edge of the space A formed by the mesh member 5 b. I can do it now.
