Abstract

PURPOSE:To provide automatic extinguishing for preventing dangerous condition by a method wherein one end of an engagement member is displaced by a plunger of a solenoid when deenergized and the other end of the engagement member is disengaged from a ratchet gear. CONSTITUTION:In a kerosene stove in which discharged gas is forcedly circulated into a room by a fan, a solenoid 23 is fixed to an angle 19a with abutment pieces 19C, 19D formed at the angle 19a. A plunger 67 is controlled for its attracting operation under a solenid 23 and arranged at the upper position opposing to a free end 51C of engagement member 51. The plunger 67 is retracted to its solid line position when the solenoid 23 is energized and in turn is descended to a dot-line position under a reaction force of a spring (not shown) when deenergized. Thus, in case that an energization of solenoid 23 is terminated, the plunger 67 pushes the free end 51C of the engagement member 51 downwardly, an engagement pin 54 is forcedly rotated in a counter-clockwise direction to release the engagement with the ratchet gear 50.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel oil stove formed of wood.

Traditional kerosene stoves are wick type, which uses a wick for combustion.
The wick type uses natural convection and has the disadvantage of insufficient circulation of hot air into the room. However, the vaporization method has the drawbacks of high power consumption and high noise.

In order to eliminate these drawbacks, there is a type of oil stove that uses a single-tube blue flame burner with a top-and-bottom wick and is equipped with a fan to forcefully circulate the exhaust gas, but the burner part is expensive. There was a drawback that the overall cost was also high.

The present invention has been made to eliminate the above-mentioned drawbacks.
A comparatively inexpensive dual-tube burner is used, and the exhaust gas from the burner is forced to circulate indoors using a fan, and the fire is automatically extinguished to prevent danger in the event of a power outage or other interruption.

In addition, the following examples do not simply replace the single-tube blue flame burner with a double-tube burner, but the CO concentration in the exhaust gas does not deteriorate even when subjected to forced blowing by a fan.
A number of measures have been taken to prevent the increase of malodorous components.

In other words, the kerosene stove of the embodiment is based on a conventional twin-tube kerosene stove, but is a new twin-tube type in which the incandescent net and coil are removed from the double-barrel burner and the outer diameter of the upper plate is increased. A burner is used to obtain a blue flame, and a box or furnace body surrounding the burner is provided, and hot air (
The exhaust gas is blown out of the device by a fan attached to the device body.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Next, FIG. 2(a) shows the internal structure of the kerosene stove of the present invention.

A detailed explanation will be given mainly with reference to (b) and (c).

First, FIG. 2(a) is a cutaway front view of essential parts of the oil stove, FIG. 2(b) is a side sectional view, and FIG. 2(c) is a plan sectional view. 15 shown in FIGS. 2(a) and (c) is the main body 1
The main outline of the U-shaped body is formed by bending a single flat plate. This body 15 includes a tank stand 18 consisting of a U-shaped angle fixed to the stand 2 with screws, etc., and an L-shaped body fixing angle 21 with both side walls and back wall screwed (20). There is.

The U-shaped tank stand 18 serves as a base for the combustion section, and a combustion tank 19 similar to the conventional one is fixed to the upper part with screws or the like.

A ventilation port 16 is bored in a part of the back wall 15a of the pod 15, and a ventilation fan 17 fixed to the fan guard 13 is provided here. Reference numeral 5 is the already mentioned louver, and is horizontally suspended between the folded portions 15c, 15c of both side walls 15b, 15b of the body 15, so as to cover the upper part of the front opening side of the body 15. Reference numeral 6 denotes the previously described front plate, and both sides thereof are hooked to the folds @1S15c, 15c of the body 15, and a portion thereof is fixed with screws (6a, 6a) (see FIG. 1(a)).

A core outer cylinder 26, a flame shielding plate 27, etc. are fixed to the combustion tank 19 fixed to the tank stand 18, and an earthquake-resistant fire extinguishing device 22 is identified by an angle 19a as in the conventional petroleum nutop. However, in the present invention, ignition and extinguishing are performed at 71. 23. Solenoid 23. A micro switch 24 etc. are added. These electrical components 2
3.24 is the terminal/ like fan 17 and power lamp 8.
Power is supplied via l/25, which will be described in detail later. Reference numeral 41 denotes a well-known center adjustment knob for lower centering, and 42 a cam plate fixed to this knob 41, which controls the on/off of the microswitch 24, which will also be described later.

A cartridge tank 39 is detachably set on the right side of the combustion tank 19, and is separated from the combustion section side by a partition plate 38. Reference numeral 40 denotes an oil level gauge for the cartridge tank 39, which is located at a position corresponding to the oil level gauge window 7 on the front plate 6.

Now, reference numeral 28 denotes a double-tube type burner placed on the core outer cylinder 26, which has a novel configuration completely different from the conventional double-tube type burner. This burner 28 is shown in FIG. 2(b).
An inner flame tube 28a, an outer flame tube 28b, an outer flame tube 28c, and a funnel-shaped upper plate 28 fitted to the upper end of the inner flame tube 28a.
It consists only of d. The outer diameter of the upper plate 28d is the same as that of the upper plate of a conventional burner, and is larger than the outer diameter of the inner flame tube 28a and smaller than the outer diameter of the outer flame tube 28b.

That is, this burner 28 is a conventional red-hot coil.

There is no net, and the diameter of the upper plate 28d is increased. According to this burner 28, the amount of CO in the exhaust gas,
The amount of malodorous components is reduced, and the blue flame inside the burner extends above the burner 28 as a blue flame, and the blue flame is extremely stable7, which was not possible with conventional burners. This is thought to be because in the burner 28, combustion heat is not absorbed by the net or coil, and the upper plate 28d has a rectifying effect.

30 is a furnace body surrounding the burner 28; body 1;
5 and prevents radiant heat from burner 28 to
It serves to guide the exhaust gas from the looper 8 to the looper 5 side as shown by the arrow. Reference numeral 31 denotes a lower furnace plate constituting the bottom surface of the furnace body 30, in which a burner 28 insertion hole is bored in the center.

This lower furnace plate 31 has its rear part secured to the back wall 15a of the body 15, and its front part secured to the reinforcing bar 29 with screws (32, 32).
) has been done. This crosspiece 29 is suspended horizontally at the front middle part of the body 15, and both ends thereof are folded parts 15c.

It is welded to 15c. Note that the rear part of the furnace bottom plate 31 is folded back downward, and is engaged with a claw (not shown) cut and raised from the body 15.

Reference numeral 33 denotes a furnace body made of a single steel plate bent nine times into a letter shape, and both lower ends are spot welded to the furnace lower plate 31. The rear side end of the furnace body 33 is bent outward by 90 degrees to form a fixing piece 33a, and together with screws for fixing the fan guard 13, the rear wall 15aK of the body 15 is identified. 33 is very solid. Since both the front and rear sides of the furnace main body 33 are open, the fan 17 corresponds to the rear side, and the looper 5 corresponds to the front side. Reference numeral 34 denotes a furnace rear inclined plate provided to close the lower side of the rear open portion of the furnace body 33, and in particular, the upper part thereof is curved forward. Both sides of this furnace rear inclined plate 34 are connected to the furnace main body 33.
It is closely fixed to both sides 33b, 33b, and its lower end is closely contacted to the furnace bottom plate 31. Reference numeral 35 denotes a furnace front inclined plate provided so as to close the lower part of the front open portion of the furnace main body 33, and the upper part thereof is curved rearward. Both sides of this furnace front inclined plate 35 are closely screwed to both sides 33b, 33b of the furnace main body 33, and the lower end thereof is in contact with the furnace lower plate 31. In other words, the surroundings of the burner 28 are the sides 33b, 33 of the furnace body 33.
b. A furnace space 36 is formed surrounded by the furnace front inclined plate 35 and the furnace rear inclined plate 34. Reference numeral 37 denotes a slit-shaped gap formed between the upper ends of the furnace front and furnace rear inclined plates 35 and 34, through which the exhaust gas from the burner 28 passes. - A space 3 through which air from the fan 7 passes between a part of each of the inclined plates 34 and 35 and the top plate of the letter-shaped furnace body 33.
7a is formed, and the looper 5 is located on the front side thereof. TH is an overheat prevention thermostat provided on the large plate, and is activated when the temperature of the furnace body 30 becomes too high due to a failure of the fan 7 or the like.

A see-through window 35b in which a mica plate 35a is fitted is formed in the furnace front inclined plate 35 at a position slightly above the upper plate 28d of the burner 28, and a burner handle 28eKJJ of the burner 28 is formed at a position corresponding to the burner handle 28eKJJ. Operation opening 35
c is formed.

1. The perspective 1 asb corresponds to the peephole 11 of the front door 9, and the blue flame of the burner 28 can be seen through the peephole 11. Also, if the front door 9 is opened, the furnace front inclined plate 3
Since the burner handle 28e protrudes from the opening 35c of the burner 28, the burner 28 can be operated.

In addition, in the drawings, FIG. 2(a) shows a state in which the furnace front inclined plate 35 has been removed, and FIG. 2(c) shows a state in which the cartridge tank 39 has been removed and the top plate portion of the furnace body 33 has been cut. Indicates the condition.

As explained above, the kerosene stove is configured so that the exhaust gas combusted with blue flame in the burner 28 is sent to the furnace space 36.
The air is introduced into the space 37a through the air-containing gap 37, and is blown out from the front side of the main body 1 in the direction indicated by the looper 5 together with the outside air blown by the fan 17. In this case, since the air blown by the fan 17 flows along the outer surface of the tilted plate 34, heat can be exchanged directly with the flange plate 34 heated by the radiant heat of the burner 28, which is efficient. Another advantage is that the air blown by the fan 17 does not affect combustion in the burner 28.

The main components of a kerosene stove are as follows:
Since this kerosene stove employs a new method of lighting the wick with an igniter, this will be explained with reference to FIGS. 3 to 6. In FIG. 3, reference numeral 43 denotes an ignition plug, which passes through the upper collar 26a of the wick outer cylinder 26 and is installed above the wick 44 with its tip raised to the ignition position. This spark plug 43 is a discharge electrode of a discharge type igniter 45 shown in FIGS. 4(a) and 4(b), and the inner flame tube 28a also serves as the other electrode. Therefore, if the igniter 45 is energized,
Electric discharge occurs from the spark plug 43 toward the inner flame cylinder 28a as shown by the dotted arrow in FIG.
The upper end of the ignites.

This point will be explained with reference to FIG. In the figure, reference numeral 46 denotes an insulator that covers the discharge electrode 43, and the tip thereof is cut obliquely with respect to the vertical direction.

The electrode 43 has a cylindrical shape, and its tip 43a has an insulator 46.
It protrudes slightly from the cut surface. The surface of this tip 43 is formed by cutting a cylinder diagonally, so it has an elliptical shape. This surface has an inclination of 5° to 20° with respect to the inner flame tube 28a, and the length between points a=b is about 2 to 3 degrees. The core 44 can be raised to point A. The combustion state is usually maintained near this position.

Now, when the wick 44 is below the point b, the discharge from the electrode 43 occurs from the point b closest to the inner flame cylinder 28a, but at this time the discharge does not hit the wick 44, so no ignition occurs. When the upper end of the wick 44 is between point b and point 4, a spark is released from the surface position corresponding to the upper end of the wick of the electrode 43a toward the inner flame cylinder 28a, licking the upper end of the wick, and the energy ignites the spark. do. In other words, the wick 44 gradually rises as the knob 41 is operated, and as it rises, the discharge position also rises, and the spark constantly passes through the tip of the wick, making it very easy to ignite1. This is thought to be because the core 44 is close to an insulator, so that a discharge is generated to avoid this. Core 44
When the wick reaches four points or more, a discharge occurs from point a, and as the wick rises to point b, which is approximately two points above the four points, the discharge is discharged toward the inner flame tube 28a as if licking the tip. However, if the discharge exceeds this point, the discharge will penetrate through the interior of the wick 44 and will not contribute to ignition of the wick at all. Note that during combustion, vaporized gas from kerosene fills between the inner and outer flame tubes 28a and 28b, so there is a risk that it may come into contact with the spark plugs (43, 46) and liquefied kerosene may flow out through the spark plugs. . Furthermore, there is a risk that air may flow into the burner through the gap between the upper flange 26a and the insulator 46, causing poor combustion. For this reason, as shown in FIG. 6(c), an oil-resistant and heat-resistant sealant 45a is applied to the insertion portion of the upper collar 26a of the insulator 146 to prevent oil from leaking and air from flowing in. This sealant 45
A is a paint containing zinc powder and epoxy resin;
There are silicone liquid gas quests, etc.

If the surface of the tip end of the electrode 43 has a width in the vertical direction as shown in FIG. In addition, as shown in FIG. 7, the tip 47a of the rod-shaped discharge electrode 47 may be bent to have a width in the vertical direction.

The igniter 45 is connected to the microswitch 24 like other electrical components, and the energization is controlled by the igniter 24. That is, the electrical components of the kerosene stove of the present invention are each connected to a power source via a microswitch 24, as shown in FIG. Note that the thermostat TH described above has the ability to cut off the power supply to the solenoid 23 when overheated. The THI is also set at 11 thermometers during overheating and is attached to one side 33a of the furnace main body 33 in FIG. 2(b), in front of the furnace front inclined plate 35 and at a height corresponding to the handle 28e. In this thermo THI, when the looper 5 is completely blocked, the warm air is
The solenoid 23 is designed to wrap around the front side of the solenoid 23 and increase the temperature there.It detects when the louver 5 is completely closed and cuts off the power to the solenoid 23.

” - The igniter 45 and other electrical components are energized through the core 44.
It is desirable to determine it uniquely in relation to the position of
Rotation amount of center adjustment knob 41 corresponding to center position Total cam plate 42
The configuration is such that the detection is performed by the microswitch 24 via the microswitch 24. Therefore, the cam plate 42 and the microswitch 24 are in a positional relationship as shown in FIGS. 4(a) and 4(b), and the fourth
Figure (a) shows the case where the wick 44 is in the extinguishing position, and Figure 4 (b)
This is the case when the core 44 is being raised. When the wick 44 is in the extinguishing position, the switch piece 24a of the microswitch 24 is located in the recess 1 part 42a of the cam plate 42, and the ignition switch 42 is turned off, so that the igniter 45 and other electrical components are not energized. . When the knob 41 is rotated in the direction of the arrow to raise the core 44, the cam plate 4
2 also rotates, and the outer circumference 42b of the cam plate 42 pushes up the switch piece 24a, turning on the switch 24 and energizing each electrical component.

The cam plate 42 determines when to turn on the micro switch 24.
The formation position of the concave portion 42a can be arbitrarily set, but in this embodiment, the core 44 is turned on when it is slightly elevated from the lowest position, and remains turned on at positions beyond that. Therefore, with the wick 44 slightly raised, the power lamp 8 is turned on, the fan 17 is rotated, and the electric discharge from the idanaic 45 is also started. Note that the solenoid 23 also operates, and its function will be described later. When the wick 44 is further removed by 1" and raised to the ignition position shown in FIG. 3, ignition occurs as described above.

The flow to the igniter 45 continues while the wick 44 is in the raised position, but the igniter 45 stops discharging approximately 20 seconds after starting discharge due to a built-in timer circuit, so that no discharge occurs during combustion. It never lasts.

FIG. 8 shows the igniter 450 circuit. In the figure, R
1, R2... are resistors, CI, C2... are capacitors, DI, D2... are diodes, Tr is a transistor, TD is a diac, SCR is a well-known SCR, and T is a transformer. 48 is a high voltage generation circuit, diac 1'
When the SCR is turned on by the trigger pulse of D, high voltage is generated in the transformer T. 49 is a timer circuit, R1
, CI turns on the transistor Tr after a certain period of time (20 seconds) after the power is turned on, so that no voltage is applied to the diac TD. For this reason,
After that, the SCR is not turned on and no high voltage is generated in the transformer T. However, once the switch 24 is turned off, the charge in the capacitor C1 naturally discharges, so when the switch 24 is turned on again, high voltage is generated again until the capacitor C1 is charged. Therefore, after extinguishing the kerosene stove, if the wick 44 is raised again, an electric discharge will occur and ignition will occur.

[About earthquake-resistant fire extinguishing equipment]

The mechanism of the fire extinguishing device 22 is completely the same as that of conventional products, but in the present invention, if the power is cut off due to some abnormality, this fire extinguishing device is activated to extinguish the fire. That is,
When the power is turned off, the vibrating weight of the fire extinguisher is overturned by the reaction of the plunger that is being attracted by the solenoid 23, and the wick is lowered as if the weight had been overturned by the vibration. The solenoid 23 in FIG. 5 is only for suctioning the plunger during energization, and when the core is moving up, the microswitch 24 is turned on and continues to suction the plunger, so there is no hindrance to the raising of the core 44. do not have.

Next, the configuration of the 11-it seismic fire extinguishing system 22 is shown in FIG. 9(a).
(b).

The explanation will be based on (c). In the figure, 19 is a combustion tank, 19a is an angle fixed to the tank 19, and 2
3.24 is a solenoid and a microswitch screwed to the angle 19a, 26 is a core outer cylinder, 41 is a core warming knob, and 42 is a cam plate, all of which have already been described.

50 is a well-known ratchet gear connected to the core adjustment shaft;
By blocking this 500 rotations of the gear, the core 44 can be held in place.

Conversely, if the gear 500 rotation prevention is released, the core 44
can be lowered all at once to the extinguishing position. In addition,
Even if the gear 500 rotation is blocked, the core temperature knob 4
If you manually rotate 1 counterclockwise, the core adjustment shaft will move to gear 5.
Since it rotates while sliding relative to 0, the wick 44 can be gradually lowered, the wick position can be adjusted, and the fire can be extinguished manually (such a mechanism for controlling the core temperature is well known; for example, 53-40977).

Reference numeral 51 denotes a retainer in the shape of an inverted "H", which is provided to control the rotation of the ratchet gear 50, and is connected to the amplifier/I/
It is rotatably supported on 19a with a stop shaft 52. This metal fitting 51 has a convex portion 51a formed at the middle lower edge, and a spring 53 that always urges the engaging tool 51 downward is not engaged with the convex portion 51a, and the free end thereof A locking pin 54 is attached to 51b so that it can be freely engaged with and detached from the teeth of the ratchet gear 50. The locking pin 54 does not engage the gear 50 when the ratchet gear 50 rotates clockwise. Therefore, when the knob 41 is turned clockwise to raise the core 44, the ratchet gear 50 does not engage the gear 50 when the ratchet gear 50 rotates clockwise. Follow it and rotate clockwise. However, when the ratchet gear 50 tries to reverse counterclockwise, the locking pin 54 engages with its teeth and prevents the reverse rotation, so that the core 44 is held at the set position. Note that when the locking pin 54 is forcibly disengaged from the teeth of the gear 50, the gear 50 becomes free, and the core 44 instantly descends.

55 is a screw 57 and a base 58 along with an operating lever 56.
It is a movable plate that is pivotally supported by the angle/L'19a through the lower end of the movable plate, and a claw 55a bent toward the front is formed on the lower side of one end, and an Ifi locking pin 55b protrudes from the free end on the opposite side. Further, a spring 59 is attached to the lower edge thereof to constantly bias the movable plate 55 in a counterclockwise direction. One end of this spring 59 is fixed to the lower protruding piece 19b of the ring (ang) v19a. Further, the wind 55a is provided in a protruding manner up to a position opposite to the lever 56 in the upper and lower directions. The base 58 is fixed to the upper part of the ankle 19a with a projection 58a and a pin 58b, and a weight support stand 60 is screwed to the upper end of the base 58. This support stand 60
A weight holder 62 having a small-diameter support leg and having a metal weight 61 fixed thereto is erected and supported.

On the other hand, at one end of the operating lever 56 there is a lever heir 63.
is attached, and above the other end is the engaging tool 51.
A free end portion 51b of the engaging member 51 is provided, and when the operation lever 56 is rotated counterclockwise, the free end portion 51b of the engagement tool 51 is pushed up by a protrusion 56a formed at one end thereof, and the locking pin 54 is pushed up.
The structure is such that the engagement with the teeth of the gear 50 is disengaged.

Reference numeral 56b denotes a projecting piece formed at the lower center edge of the operating lever 56, and one end of the spring 53 is locked therein. A track plate 64 is rotatably supported on the left end of the base 58 by a stepped screw 65, and a weight 61 and a weight receiver 62 placed on the support base 60 are mounted on one end of the track plate. The lower end of a string or chain 66 is fixed to the support base 60 through the hole 60a, and the lower end of the string or chain 66 is fixed to the plate surface with ld r'< j
A letter-shaped slot 64a is bored 3, the slot 64a
A locking portion 64b that allows the locking pin 55b of the moving plate 55 to be freely engaged and detached is provided in a protruding manner at the bent portion.

Now, with the locking pin 55b of the movable plate 55 locked to the locking portion 64b of the actuating plate 64, when the weight receiver 62 is released from the support stand 60'', the actuating plate 64 is attached to the string or chain 66. Since it is pulled and rotated counterclockwise, the locking pin 55b of the movable plate 55 is disengaged from the locking portion 64b due to the urging force of the nub ring 59 and rotates counterclockwise. This movable plate 5
The rotational force of 5 is transmitted to the operating lever 56 by engagement of the claw 55a and the free end of the lever 56, and the free end 51b of the engagement tool 51 is pushed up by the one end 56a of the operating lever 56.
[Engagement 1] Release the engagement between the nip pin 54 and the gear 50. The retainer 51 is at the position indicated by the dashed-dotted line in FIG. 9(1)).

- To reset the weight receiver 62 to its original state, rotate the lever 56 clockwise using the lever knob 63, and press the claw 55a that contacts the lever 56 clockwise to move the movable plate 55 clockwise. Make him waste one time. When the locking pin 55b moves up the slot 64a due to this rotation, the actuating plate 64 is rotated clockwise and the handle 6
6 is pulled downward, the weight holder 62 is attached to the support base 6.
0" will be installed on the second floor.

The solenoid 23 is a contact piece 1' formed on the angle 19a.
It is fixed to the angle 19a using 9C and 19D. 67 is a plunger whose suction is controlled by the solenoid 23, and is opposed to the free end 51C of the engagement tool 51.
It is located in one position. When the solenoid 23 is energized, this plunger 67 is attracted and is
)), and when the trace "1L" is stopped, the repulsive force of a spring (not shown) lowers it to the position indicated by the dashed dot line in the figure.

Therefore, when the solenoid 23- is de-energized, the plunger 67 presses the free end 51C of the engagement tool 51 downward, forcibly rotates the locking pin 54 side counterclockwise, and the ratchet gear 50 cancel the bond with

Here, the overall operation of the earthquake-resistant fire extinguishing system 22 will be explained.

First, use the lever heir 63 to operate the operating lever 56.
When the movable plate 55 is lifted in one direction and rotated clockwise, the locking pin 55b moves upward along the slot 64a and locks into the locking portion 64b.
At the same time as being locked upward, the actuating plate 64 is rotated clockwise and the weight receiver 62 is placed on the support base 6O-L-. Next, when you hold the legitimate child 41 and rotate the rotating shaft clockwise,
The rotational force is transmitted to the rank plate via the pinion gear and the rack gear, and the core 44 is moved upward against the return spring, while the cam plate 42, ratchet 1, and gear 50 rotate.

In this state, the cam plate 42 turns on the microswitch 24, energizes the solenoid 23, and the 1-lunger 67 is in the suction position. Since the lever 55 is in the position shown in FIG. 9(b), the engagement tool 51 is pulled by a spring 53 and secured to the ratchet 1 gear 50. When the rotation of the rotating shaft is stopped, the upward movement of the core is stopped and the return spring is attached to the locking pin 5 of the retainer 51.
4 engages with the teeth of the gear 50 to prevent the gear 50 from rotating in reverse, and the dowel core 6 is held at the set position. Therefore, for combustion, it is sufficient to ignite the tip of the wick 44, or to reduce the firepower, the rotating shaft may be rotated counterclockwise. As described above, combustion is performed in the same manner as in the conventional combustion apparatus in the normal combustion state.

If an earthquake or the like occurs during normal combustion and the weight 61 and weight holder 62 are separated from the support base 60, the actuating plate 64 is pulled by the string or chain 66 and rotates counterclockwise. Therefore, the locking pin 55b of the movable plate 55 is disengaged from the locking portion 64b by the urging force of the spring 59, and rotates counterclockwise. The rotation force of the movable plate 55 is transmitted to the operation lever 56 by the engagement of the protrusion 55a and the lever 56, and the protrusion 56a at one end of the operation lever 56 pushes up the free end of the engagement tool 51, causing the locking pin 54 to move upward. and the gear 50 are disengaged. Therefore, the wick 44 is rapidly lowered by the restoring force of the return spring, and the fire is instantly extinguished.

For the next operation of the fire extinguishing system, it is sufficient to move the operation lever 56 upward using the lever heir 63, and by doing so, the movable plate 55 rotates clockwise and locks the locking pin 55b.
is locked by a locking portion 64b of the actuating plate 64.

In addition, if you want to manually extinguish the fire, use the regulation spring 53.
By doing so, one end of the operating lever 56 pushes up the free end 51b of the engagement tool 51 and locks the locking pin 54 and the gear 50.
is disengaged from the teeth.

In addition, when power is cut off to the solenoid 23 during a power outage or when the overheating thermostats TH, THI, etc. are activated, the plunger 67 is lowered and the left end 51C of the retainer 51 is pushed down, and the locking pin 54 is pressed down. Since the latch gear 50 and the latch gear 50 are no longer engaged, the core 44 is instantly lowered. At this time, the cam plate 42 is also struck and the microswitch 24 is also turned off, so that the solenoid 23 is not energized, for example, when the power is turned on again after a power outage.

In this way, the fire extinguishing device 22 detects an abnormal temperature rise in the kerosene stove and automatically extinguishes the fire.
Accidents can be prevented. Furthermore, the configuration is extremely simple, consisting of adding a solenoid to a conventional vibration sensor. Furthermore, if the energization of the solenoid 23 in this fire extinguishing device 22 is controlled by a timer,
Even though it is a wick type kerosene stove, it can be configured to automatically extinguish the fire after a predetermined period of time.

[Operation and operation of the kerosene stove of the present invention] First, when the front door 9 is opened in the state shown in FIG.
The core temperature knob 41 etc. are exposed. Therefore, when the knob 41 is rotated clockwise, the wick 44 is raised by a well-known mechanism, the cam plate 42 turns on the microswitch 24, the plunger 67 is pulled by the solenoid 23, and the fire extinguisher 22 is turned on.
becomes normal. Therefore, the core 44 rises to the position where the knob 41 is rotated, and can be held at that position. In this state, the power lamp 8 lights up to indicate energization, and at the same time, the fan 7 rotates and starts blowing air. Therefore, cold air is blown out from the looper 5.

The igniter 45 starts discharging from the spark plaque 43, but in this state the wick 44 is at the end of the inner and outer flame tubes 28a, 28b.
It does not rise during this time and the wick 44 is not ignited. When the knob 41 is further turned, the wick 44 moves to the inner and outer flame tubes 28 as shown in FIG.
Since it is exposed between a and 28b, it is ignited by the operation described above. The spark plug 43 continues discharging until a predetermined one hour timer elapses, and then automatically stops discharging.

When the wick 44 is ignited, the oil begins to burn with a blue flame, as is well known. The blue flame has an upper plate of 28d unlike the conventional burner.
It extends to nearby areas and burns visually beautifully. This state can be confirmed through the see-through window 35b, and can be seen through the viewing window 11 even if the front door 9 is closed. If the combustion flame is unstable and out of shape, remove the burner handle 28.
Shake the burner 28 from side to side with e to stabilize the combustion flame. After ignition, the hot air from the burner 28 lasts for a very short time (approximately 1
1 minute), the fan 7 rises from the gap 37 to the space 37a.
The hot air is discharged outside the appliance through the looper 5 as warm air. As mentioned above, the amount of CO in the hot air and the amount of bad odor components are small, so there is no bad odor in the room1.
After confirming ignition and combustion, if the front door 9 is closed, combustion will occur automatically from then on, hot air will be emitted to the front side, and efficient heating will be performed.

To extinguish the fire, simply open the front door 9 and rotate the core temperature knob 41 counterclockwise. As the knob 41 rotates counterclockwise, the wick 44 descends to extinguish the fire, and the recess 42a of the cam plate 42 turns off the microswitch 24 in response to the nut piece 24a. Therefore, the plunger 67
activates the seismic sensor 22 to return the ratchet gear 50 to its original state, and at the same time stops energizing the fan 17 and lamp 8 to return to the initial state.

In the combustion state, if a power outage occurs or the power cord is pulled out and the electricity stops, the suction of the plunger 67 of the solenoid 23 is immediately released and the engaging tool 51 rotates counterclockwise, so that the wick 44 is It descends and is extinguished when it warms up. In this case, since the cam plate 42 also returns to its original position, the microswitch 24 is turned off, stopping the drive of the fan 17 and the power supply to the power lamp 8 when the power is re-energized.

Also, if the temperature inside the furnace rises abnormally by 1'' due to a malfunction of the fan 17, complete blockage of the looper 5, or any other reason, the overheating thermos TH and THI will operate to stop energizing the solenoid 23, and the above will occur. Extinguish the fire by dropping the wick in the same way as in the case. In this case as well, since the microswitch 24 is turned off by the cam plate 42, the power supply to the fan 17 and the power lamp 8 is also stopped.

The power lamp 8 has a unique advantage in that it can also be used as a safety confirmation lamp to indicate whether the wick 44 has fully descended.

As mentioned above, the kerosene stove of the present invention uses a wick to burn oil, so it is quiet and has no combustion noise. In addition, if the electrical system becomes uncontrollable due to a power outage, etc., the fire is automatically extinguished by dropping the wick, making it extremely safe.
