Description

[Detailed description of the invention] The invention consists of an operating knob that controls ignition, combustion amount, and extinguishing of the burner, and an electromagnet that is turned on and off in conjunction with this operating knob, which opens when the electromagnet is energized and releases liquid fuel. Regarding a control device for a liquid fuel combustion device equipped with an electromagnetic oil amount controller that supplies the oil to a burner, the combustion air that is blown from a blower into a polycrystalline substance impregnated with liquid fuel such as petroleum is used. The present invention relates to a control device for a liquid fuel combustion device that sprays fuel vaporized from a porous material, mixes it with combustion air, and burns it.

The present invention is equipped with a manual operation mechanism that holds the valve of the electromagnetic oil flow controller open so that combustion can be continued even in the event of a power outage. By closing the valve part of the controller, the inconvenience of combustion being extinguished during a power outage is eliminated, and the extinguishing operation is also convenient.

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

The liquid fuel combustion device in this embodiment blows combustion air blown from a blower onto a porous material impregnated with liquid fuel such as petroleum, and mixes the fuel vaporized from the porous material as combustion air. It is of a combustion type, and more specifically, it includes a burner having a vaporization part and a combustion part in which a porous material impregnated with liquid fuel is arranged, and a liquid fuel supply path that supplies liquid fuel to the porous material in the burner. and,
This system includes an air supply path for supplying fuel air to the burner using a blower.

In this liquid fuel combustion device, when the amount of air blown to the burner is increased, the amount of fuel vaporized increases as well as the amount of combustion air.
Conversely, if you reduce the amount of air blown to the burner, the amount of fuel vaporized will decrease as well as the amount of combustion air, and the air-fuel ratio (ratio of air to fuel) will always remain constant, so the amount of air blown to the burner will be controlled. By simply doing this, you can easily and steplessly control the amount of combustion, and even if you change the amount of combustion, you can always maintain a good combustion state.

Air sent from the combustion blower 1 is controlled by a damper 2 and sent to the burner.

The combustion amount of the burner is proportional to the above-mentioned amount of blown air.

Therefore, operating this damper 2 adjusts the combustion amount.

On the other hand, liquid fuel passes through the oil amount controller 4 from the outer tank as shown by arrow a, and is sent to the burner as shown by arrow s.

A valve portion is provided within the oil amount controller 4, and a push-down pin 5 for closing the valve projects from the upper portion of the oil amount controller 4.

Liquid fuel flows from arrow a to arrow b only while this valve and pin 5 are pushed upward by a spring or the like.

A lever 7 that swings about a fulcrum 6 is provided above the push-down pin 5, and one end of this lever 7 is inserted into a notch 9a of a plunger 9 of an electromagnet 8.

When the electromagnet 8 is not energized, the plunger 9 is pushed up by a compression spring 10 provided at one end of the plunger, and the lever 7 pushes down the push-down pin 5 to stop oil feeding.

When the electromagnet 8 is energized, the plunger 9 is attracted against the spring 10, the lever 7 is separated from the tip of the push-down pin 5, and oil is supplied.

The electromagnet 8 is energized by the cam 1 provided on the damper operating shaft 3.
1 is performed by pressing switch 12.

When this switch 12 is turned on, in addition to energizing the electromagnet 8, the blower 1 is started and the heater is ignited (not shown) at the same time, and combustion is started.

On the other hand, in order to continue combustion even in the event of a power outage, a measure is required to continue oil supply even when power to the electromagnet 8 is cut off.

Therefore, another lever 13 is provided centered on the fulcrum 6, and an adjustment screw 14 is provided at one end of the lever 13 so that the lever 7 can be swung by a certain amount.

Therefore, by pushing down the lever 7 using the lever 13, even when the electromagnet 8 is not energized, the valve portion of the oil amount controller 4 can be held open and oil can be fed.

The adjustment screw 14 is used to arbitrarily adjust the amount of oil fed at this time within the amount of oil fed when the electromagnet 8 is energized.

The other end of this lever 7 is connected to an operating shaft 17 via a ring 15 and a lever 16.

Therefore, by rotating this shaft 17, it is possible to continue combustion during a power outage.

However, when turning on the power, operate this shaft 17 clockwise as shown in the figure, and turn the combustion adjustment knob 19 to extinguish the fire while leaving it in a state where combustion is possible during a power outage.If the oil supply is not cut off, the fire will not actually be extinguished. .

Therefore, in order to ensure that the fire is extinguished even if the user forgets to operate it, when the operating knob 19 is set to the fire extinguishing side,
The shaft 17 for continuing combustion during a power outage also needs to be rotated to the oil supply stop side in conjunction.

A cam 18 having a cam surface 18a is provided on the shaft 17, and the cam surface 2
A cam 20 having a diameter of 0 a is provided on the shaft 3, and a reset lever 2 that can swing around a pin 21 is provided in the middle thereof.
2 provided at both ends of this lever 22.
pins 23, 24 and the cam surfaces 18a, 20
a are opposite to each other.

When the operating knob 19 is turned to the extinguishing position, the cam 20 rotates the lever 22 by the cam surface 20a, and the operation is controlled by the pin 23. It is transmitted to the shaft 17 via the cam 18 and moves the lever 13 away from the lever 7 driven by the electromagnet.

Therefore, oil supply will be stopped.

The leaf spring 25 is inserted into the grooves 18b and 18 provided in the cam 18.
It is inserted into C and is used to stop the shaft 17 at these two positions.

The spring 26 is arranged so that the pin 24 of the lever 22 is connected to the cam surface 2 of the cam 20.
This is to ensure that it is always in pressure contact with 0a.

As described above, according to the present invention, by manually locking the locking mechanism, even if the electromagnet is demagnetized due to a power outage, the valve of the oil flow controller remains open and combustion continues. Furthermore, when extinguishing the fire after that, the lock can be released and the valve portion closed with the extinguishing operation, thereby stopping the combustion.

Therefore, it is possible to eliminate the inconvenience of extinguishing combustion due to a power outage, and it is convenient to use because only one extinguishing operation is required to extinguish the fire.
