Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a liquid fuel combustion device such as a wick type oil stove, and more particularly to a combustion device capable of drastically adjusting the combustion amount.

(Prior Art) Conventionally, the wick type oil stove has a fixed amount of protrusion of the wick, which makes it difficult to adjust the combustion amount, but thereafter, the protrusion of the wick is within an allowable range in which exhaust gas components do not deteriorate. Oil stoves have become commonplace that are adjustable in quantity to allow for controlled combustion. However, the combustion amount in this type of oil stove can be adjusted only to 90-80% of the maximum combustion amount, so when the room temperature rises excessively, it is necessary to extinguish the fire or open the window to adjust the room temperature. There was a problem in terms of sexuality and economy.

Therefore, as shown in Japanese Utility Model Publication No. 50-113930 or Japanese Utility Model Publication No. 55-22325, the wick covered with one combustion cylinder is divided into front and rear, and the front and rear wicks are independently provided. An oil stove has been proposed that can appear and disappear, and the amount of combustion can be adjusted significantly.

However, in such a petroleum stove structure, since the combustion heat applied to the combustion tube is uneven, particularly during small combustion in which only one wick is burned, thermal deformation of the combustion tube due to a temperature difference is likely to occur. Further, since there is only one combustion cylinder and its volume is constant, the combustion balance is disrupted when switching between a large combustion in which both wicks are burned and a small combustion in which only one wick is burned, and the flame rises easily. Is likely to occur as an excessive phenomenon, or exhaust gas such as odor is likely to be deteriorated during a small combustion.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, in order to make it possible to adjust the combustion amount to a large extent, one combustion cylinder is provided, and the wick is divided among them. There has been a problem that thermal deformation of the cylinder, standing flame, soot, generation of odor, deterioration of exhaust gas and the like are likely to occur.

Therefore, an object of the present invention is to provide a liquid fuel combustion apparatus capable of drastically adjusting the combustion amount and preventing thermal deformation, standing flame, soot, odor generation, and deterioration of exhaust gas of a combustion cylinder. And

[Construction of the Invention] (Means for Solving the Problems) The present invention divides the combustion tubes 15 and 16 into a plurality of upper and lower sections, and links the plurality of combustion sections 15 and 16 with the movement of the adjusting body 90. And can be combined and separated in the vertical direction.
An interlocking mechanism 99 for cooperating the adjusting body 90 and the operating body 67 of the wick 14 is provided so that the protrusion amount of the wick 14 becomes small when the plurality of combustion tubes 15, 16 are separated.

(Action) The present invention utilizes the flame focusing action of the combustion tubes 15 and 16,
The combustion amount is adjusted by connecting or separating a plurality of combustion tubes 15 and 16 which are vertically divided. That is, when a plurality of combustion tubes 15 and 16 are combined, the combustion amount increases,
The amount of combustion becomes small when separated. Also, the combustion tubes 15, 16
By moving the wick 14 up and down in conjunction with the coupling and disconnection of the wick, and increasing the protrusion amount of the wick 14 during large combustion and decreasing it during small combustion, the liquid fuel vaporized due to changes in the effective volume of the combustion chamber. Match the amount of vaporized gas and its draft force. In this way, the combustion state is stabilized during large combustion, small combustion, and when switching between the two, transient flame rise and soot occur during switching, insufficient red heat due to insufficient vaporized gas, and odor. And prevent the generation of carbon monoxide. In addition, the connection and separation of the combustion tubes 15 and 16 and the wick 14
Since the adjusting body 90 and the operating body 67 are made to cooperate with each other to interlock with the vertical movement of the wick, the wick 14 and the combustion tubes 15 and 16 are interlocked in a stable state without interfering with the seismic mechanism.

Next, the operation of the above configuration will be described.

First, the operation of the wick lifting mechanism 43 will be described.

As shown in FIG. 1, when the operation knob 67 is pushed down along the slider guide 64, the operation lever is interlocked with it.
As 63 rotates clockwise, this operation lever
63 together with operating shaft 47, core vertical shaft 48 and lifting plate 54
Rotates in the clockwise direction, and the wick 14 is projected onto the fire plates 10 and 12. Further, as the operation lever 63 rotates, the operation lever 63 pushes the lower restricting piece 62 of the interlocking lever 59 from above to rotate the interlocking lever 59 in the clockwise direction. Locking pin 61 of lever 59 is arcuate groove 72
, The interlocking lever 59 is held in the state of being rotated clockwise against the biasing force of the return spring 60, and the wick 14 is also held in the protruding state. . Further, when the operation knob 67 is pushed down in this manner, the cooperating body 101 provided in the engaging groove 100 of the slider 65 on the operation knob 67 side and the slider 86 on the adjustment knob 90 side located below the slider guide 85 is provided. Engage both sliders 6
5,86 are integrally connected.

Here, for example, when a heater (not shown) is energized and brought into contact with the protruding wick 14, the wick 14 is ignited to start combustion. Then, if the operating knob 67 is pushed up slightly during this combustion operation, the operating lever 63 will move the interlocking lever 59.
Of the control piece 62 is rotated counterclockwise and the operation shaft 47, the core up-down shaft 48 and the lifting plate 54 are rotated counterclockwise, and the wick 14 is slightly pulled down to adjust the heat power. It In this case, the engagement knob 100 is engaged with the engagement portion 102 of the cooperating body 101, so that the adjustment knob 90 is also slightly raised to drive the drive lever 91.
Rotates counterclockwise, but the notch in the drive lever 91
The drive shaft 93 does not rotate due to the play between the back bent portion 93c of the drive shaft 93 and the drive shaft 93, and therefore the upper combustion cylinder 16 does not move.

To extinguish the fire, push up the operating knob 67 strongly. Then, the operating lever 63 presses the upper restricting piece portion 62 of the interlocking lever 59 from below, and a strong counterclockwise force is applied to the interlocking lever 59 to resist the urging force of the clutch spring 76. , Locking pin of interlocking lever 59
61 is forcibly disengaged from clutch 75. Next, since the locking pin 61 is disengaged from the clutch 75, the interlocking lever 59 is rotated counterclockwise by the urging force of the return spring 60, and the regulating piece 62 below the interlocking lever 59 is operated. The lever 63 is pressed from below, and the operation lever 63 rotates counterclockwise. Then, the operation shaft 47 and the core up-down shaft 48 rotate in the counterclockwise direction integrally with the operation lever 63, and the wick 14 is lowered and retracted, thereby extinguishing the fire. In this case, adjust knob as the operating knob 67 rises.
The cooperation member 101 on the 90 side is disengaged from the engagement groove 100, and the adjustment knob 90
Is separated from the operating knob 67.

When a force is applied to the device body 1 such that the device body 1 is tilted due to an earthquake during combustion, the pendulum 80 shakes and the flange 78 of the pendulum shaft 79 causes the sensing piece of the clutch lever 73 to move. The portion 77 is allowed to float, the clutch lever 73 rotates, and the clutch 75 disengages from the locking pin 61 of the interlocking lever 59. Then, in the same manner as described above, the wick 14 is immersed and the fire is extinguished.

Further, when extinguishing the fire, it has been described above that the operation knob 67 is strongly pushed up, but for example, a pendulum 80 is manually operated by a fire extinguishing operation unit (not shown) vertically provided on a lower reflecting plate (not shown).
The fire may be extinguished in the same manner as described above by forcibly tilting.

Further, when the fuel tank 5 is removed during combustion, as the fuel tank 5 moves away from the sensing body 83 of the operating lever 81, the urging force of the operating spring 82 causes the operating lever 81 to move in the counterclockwise direction. When rotated, the operating lever 81 pushes the sensing piece 77 of the clutch lever 73 from below to rotate the clutch lever 73 counterclockwise. Along with that, the clutch 75 of the clutch lever 73 is connected to the interlocking lever 59.
The wick 14 is disengaged from the locking pin 61 and the wick 14 is immersed and the fire is extinguished in the same manner as described above.

Next, the operation of the combustion cylinder elevating mechanism 44 will be described.

When the adjusting knob 90 is pushed down as shown in FIG. 1, the upper combustion cylinder 16 is in a lowered state and is engaged with the lower combustion cylinder 15.

Then, as shown in FIG. 2, when the adjustment knob 90 is pushed up, the drive lever 91 is rotated in the counterclockwise direction by the engagement of the slotted notch 91a and the shaft body 88. Along with that, the drive shaft 93 rotates rightward due to the engagement between the rear bent portion 93c and the cutout portion 94, and the left bent portion 93d on the rear end side of the drive shaft 93 rotates upward. . Then, the shift plate 98 and the drive rod 96
However, due to the engagement between the long hole 97 of the shift plate 98 and the rear curved portion 93e, the drive rod 96 pushes up the movable rod 41, and the upper combustion cylinder 16 is integrally formed with the movable rod 41. Rise,
It is separated from the lower combustion cylinder 15. Further, the opening / closing body 42 of the movable rod 41 is located inside the air passage port 22 of the engaging portion of both combustion cylinders 15 and 16, and substantially closes the air passage port 22. On the other hand, as the adjusting knob 90 rises, the operating knob 67 also rises due to the engagement between the cooperating body 101 and the engaging groove 100, and the operating lever 63 becomes the interlocking lever.
Although it rotates counterclockwise by the amount of play with the restriction piece 62, when the operating lever 63 engages with the restriction piece 62, the return spring 60
Before turning the interlocking lever 59 against the urging force of the
The elasticity of 1 disengages the engaging portion 102 of the cooperative body 101 from the engaging groove 100. Therefore, the operating lever 63 is slightly raised by the amount of the play, and the operating lever 63 is rotated counterclockwise accordingly, so that the wick 14 is lowered and the protrusion amount thereof is reduced.

On the other hand, if you push down the adjusting knob 90,
As 91 rotates in the clockwise direction, the drive rod 96 descends, the movable rod 41 and the upper combustion cylinder 16 descend due to their own weight, are coupled to the lower combustion cylinder 15, and the opening / closing body 42 also descends. Then, the air passage port 22 is opened. Along with this, the cooperative body 101 engages with the engaging groove 100 while the adjusting knob 90 is descending, and descends integrally with the operating knob 67. Then, the operation lever 63 rotates in the clockwise direction to raise the wick 14 and increase the amount of protrusion.

In this case, by interlocking with the movement of pushing up the adjusting knob 90, the clutch lever 73 is lowered to rotate the interlocking lever 59 counterclockwise by the urging force of the return spring 60, thereby operating the operating lever 63 counterclockwise. It is conceivable that the wick 14 is rotated in the direction to lower the wick 14, but in this case, in order to repeat the rotation of the clutch lever 73 every time the combustion amount is adjusted, the pendulum 80 is locked with the clutch 75 when tilted. Although it is expected that the fire extinguishing operation will become unstable due to variation in the operating point where the pin 61 is disengaged, in the above-mentioned embodiment, the operation knob 67 and the adjustment knob 90 are for cooperative operation by connecting and disconnecting. With this, the protrusion amount of the wick 14 can be reduced when the combustion cylinders 15 and 16 are separated without rotating the clutch lever 73. Therefore, the tilt of the pendulum 80 causes the engagement between the clutch 75 and the locking pin 61. You can easily set the operating point of the configured seismic mechanism as released.

Next, the combustion action will be described.

The combustion is performed in the combustion chamber between the inner flame cylinders 18 and 30 surrounding the wick 14 and the outer flame cylinders 24 and 35. However, due to the focusing effect of the flames of the inner flame cylinders 18 and 30, both combustion cylinders 15 and 16 are The amount of combustion increases when they are combined, and decreases when they are separated. That is, the combustion amount can be significantly adjusted by connecting and separating the two combustion cylinders 15 and 16 in this way, and the upper combustion cylinder 16 or the wick can be adjusted.
By changing the height of 14, the adjustable width of the combustion amount can be set arbitrarily.

The supply of combustion air to the combustion chamber is performed through the lower air intake port 28 and the air hole 23 of the lower outer flame tube 24 at the time of small combustion, and the lower end opening of the wick guide 11 and the inside thereof. The guide plate 95, the lower guide disc 19 of the lower inner flame cylinder 18, and the air holes 17 of the lower inner flame cylinder 18 are used. In addition, during heavy combustion, in addition to this, the air guide tube 40 and the lower glass restraint 25
, The upper air intake 38 and the upper outer flame tube 35
Through the air holes 34 of the lower rectifying plate base 20
And an air passage port 22 of the lower flow plate 21, an upper guide disc 31 in the upper inner flame cylinder 30, and an air hole 29 of the upper inner flame cylinder 30.

According to the above configuration, the combustion heat is uniformly applied to the respective combustion cylinders 15 and 16 in the circumferential direction during both the large combustion and the small combustion, so that the thermal deformation of the combustion cylinders 15 and 16 due to the temperature difference. Does not occur. Further, at the time of small combustion, the gap between the air control cylinder 39 and the lower glass restraint 25 becomes large by the amount of rise of the upper combustion cylinder 16, so a large amount of cool air is introduced from the outside. Then, this cold air is introduced into the lower combustion cylinder 15, is utilized as secondary combustion air, and has an action of cooling the upper combustion cylinder 16 against heating by the flame of the lower combustion cylinder 15, Thermal deformation of the upper combustion cylinder 16 is unlikely to occur, and stable performance can be maintained for a long period of time.

Further, as described above, the protrusion amount of the wick 14 becomes large when the combustion cylinders 15 and 16 are combined and becomes small at the time of separation, so that the evaporation amount of the liquid fuel becomes large when the combustion cylinders 15 and 16 are combined and at the time of separation. Get smaller. That is, the amount of vaporized gas in which the liquid fuel is vaporized and its draft force are matched with the change in the effective volume of the combustion chamber. Therefore, a stable combustion state can be obtained during the large combustion, the small combustion, and the switching between the both. For example, when the large combustion is switched to the small combustion, the amount of the vaporized gas and its draft force decrease as the effective volume of the combustion chamber decreases, so that transient phenomena such as the occurrence of standing flame and soot are prevented. On the contrary, when the small combustion is switched to the large combustion, the amount of vaporized gas immediately increases, so that the response speed of the combustion switching is fast and the lack of red heat due to the shortage of vaporized gas does not occur. Further, deterioration of exhaust gas such as generation of odor and carbon monoxide is also prevented. Further, each of the combustion cylinders 15 and 16 has air intake ports 28 and 38 on the outer peripheral side, respectively, and the air passage port of the joint portion of both combustion cylinders 15 and 16 is also provided.
Since 22 is also closed at the time of separation, the combustion air is effectively supplied during both the small combustion and the large combustion, and the combustion state is further stabilized. Furthermore, since the operation knob 67 and the adjustment knob 90 are made to cooperate with each other by engaging and disengaging the engaging portion 102 and the engaging groove 100 of the cooperating body 101 so that they can be coupled and separated, without interfering with the clutch lever 73. , Vertical movement of the wick 14 and the combustion tubes 15, 16
