JPH03225111A - Deodorizing and combustion assisting device of kerosene burner - Google Patents

Abstract

PURPOSE:To provide the effect of combustion assisting at the time of build-up of combustion during ignition and the shortening of the time of fire extinguishing during fire extinguishing and the effect of suppressing odor by supplying the outside air to the space above an oil tank during ignition and exhausting to the outside of the oil tank unburned gas that stays in the upper space during fire extinguishing by rotating a motor positively or reversely. CONSTITUTION:During ignition the wick is advanced into the lower section of a heat chamber 3. When a burner is ignited, the kerosene fuel starts vaporization through the wick, and the combustion is made in the heat chamber 3. During this ignition operation a motor 4 is rotated positively for a certain time to supply air into an oil tank 1 from a supply air chamber 6 by a fan 5. Since the air is sent as combustion air into the heat chamber 3 through a small gap between the wick and a wick receiving cylinder 2, the build-up of combustion is made rapidly, and the transfer to constant combustion is rapid. Next, during fire extinguishing, the wick is lowered into the wick receiving cylinder 2 for fire extinguishing operation, and at this time a motor 4 is rotated reversely for a certain time and the unburned gas that is staying in the oil tank 1 is exhausted to the outside via a suction port 8 and an intake chamber 6a by a fan 5a to shorten the time of fire extinguishing, and at the same time the unburned gas is kept from ascending to the combustion cylinder and bad odor is not generated.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an oil combustor that uses a wick to suck up and burn fuel from an oil tank, which promotes the rise of combustion when ignited and reduces odor when extinguished. It is something to do.

[Conventional technology]

Oil burners, which use a wick to suck up fuel from an oil tank and vaporize and burn it, have been widely known as oil stoves and oil heaters. Most of them are indoor exhaust type, and combustion performance is usually stable due to improvements in performance.
When a fire is ignited or extinguished, a foul odor is emitted into the room for a while, causing discomfort to the user.

Therefore, recent products have adopted a method that uses a catalyst to reburn the unburned gas, and a method that forcibly releases the unburned gas in the oil tank outside the vessel when extinguishing a fire to reduce the odor. ing.

[Problem to be solved by the invention]

The present invention is an improvement proposal for the latter forced release among the above-mentioned conventional techniques. In other words, although recent oil burners do not produce unpleasant odors during combustion and have become stable products, they still require the use of DC motors and fans only to reduce the odor when extinguishing fires. First, it is uneconomical considering the frequency of use.

Therefore, it is desirable to utilize a fan installed at a beveled angle for a variety of purposes.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention rotates the motor in forward and reverse directions, sends outside air to the upper space of the oil tank (the part that communicates with the combustion cylinder) when igniting, and conversely, the air that accumulates in the upper space when extinguishing the oil tank. The structure is such that fuel gas is discharged to the outside of the oil tank.

That is, in an oil combustor equipped with an oil tank 1 and a core cylinder 2 and a combustion cylinder 3 above the oil tank 1, fans 5 and 5a whose air blowing direction is opposite to that of the motor 4 are installed at appropriate locations outside the oil tank 1. A ventilation chamber 6 and a suction chamber 6a are provided on one axis, and an oil tank 1 is provided.
The blower lower and suction port 8, which communicate with the inner upper space A, are connected to the blower chamber 6 and the suction chamber 6a, respectively, so that the motor rotates forward and backward during ignition and extinguishing, and also maintains constant forward and reverse rotation. This invention relates to a deodorizing and auxiliary combustion device for an oil combustor configured to operate continuously. When igniting, the motor 4 is rotated in the forward direction, and the fan 5 blows air from the ventilation chamber 6 into the oil tank 1.
When extinguishing a fire, the fan 5a rotates in the opposite direction and discharges unburned gas from the oil tank 1 to the outside of the vessel via the suction chamber 6a, thereby easily deodorizing and auxiliary combustion.

[Effect]

The ignition operation is the same as the normal operation of this type of combustor. When the wick is advanced to the lower part of the combustion tube 3 and ignited by an appropriate method, the petroleum fuel starts to vaporize through the wick and inside the combustion tube 3. Perform combustion. During this ignition operation, the motor 4 is rotated in the forward direction for a certain period of time, and the fan 5 blows air from the ventilation chamber 6 into the oil tank 1, and then sends it as combustion air to the combustion tube 3 through the small gap between the wick and the wick cylinder 2. , the startup of combustion occurs quickly, and the transition to steady combustion is quick.

Next, when extinguishing a fire, the wick is lowered into the wick container 2 and the fire is extinguished. At this time, the motor 4 rotates in reverse for a certain period of time, and the fan 5a sucks in the unburned gas remaining in the oil tank 1. It is discharged outside the vessel through the port 8 and the suction chamber 6a, thereby shortening the extinguishing time and preventing unburned residue from rising into the combustion tube, thereby preventing the generation of a bad odor.

〔Example〕

The configuration will be explained below with reference to figures showing an embodiment. 1 is an oil tank, 2 is a wick cylinder connected to the oil tank 1, 3 is a combustion cylinder placed on the wick cylinder 2, and 4 is for ignition and extinguishing. A motor that changes the direction of rotation between forward and reverse at different times, and is installed at a suitable location outside the oil tank 1. 5 and 5a are two fans equipped with scrolls of different blowing directions on both shafts or one shaft of the motor 4, and 6 is a ventilation chamber equipped with the fan 5, which blows outside air when the motor 4 rotates in the forward direction. 6. Introduce into the oil tank 1 via the blower lower. 6a is a suction chamber equipped with a fan 5a, and when the motor 4 rotates in reverse, unburned gas in the oil tank 1 is discharged to the outside of the oil tank 1 through the suction port 8 and the suction chamber 6a. Numeral 9 is a wick housed in the wick cylinder 2, and the fuel in the oil tank 1 is sucked up by the wick 9 and sent to the combustion cylinder 3.
Burn it inside.

Reference numeral 10 denotes a double switch that is switched in conjunction with the up and down of the wick 9. When the wick is raised, a series circuit of the ignition timer 11 and the motor 4 can be formed, and the motor 4 is rotated at a certain time set by the ignition timer 11. do. Also, when the wick is lowered and the fire is extinguished, the switch 10 changes, forming a series circuit of the fire extinguishing timer 12 and the motor 4, and the motor 4 is energized from the opposite direction for a certain period of time, rotating in the opposite direction to the direction of rotation when igniting. do. Note that the blowing direction of the air is determined by the shape of the fans 5 and 5a and the air blowing chamber 6 and suction chamber 6a, so even if the fans 5 and 5a are installed on the same axis and rotate together, air will be blown from one fan. If it is, air will not be blown even if the other fan is rotating.

〔effect〕

The present invention configured as described above provides fans 5 and 5a with different air blowing directions on both shafts or one shaft of the motor 4.
・Since the fan 5a is provided in the ventilation chamber 6 and suction chamber 6a, which are set at an appropriate angle of 4 degrees outside the oil tank 1, when the motor 4 is rotated forward at the time of ignition, the fan 5 acts as a ventilation fan and blows the outside air into the oil. Air is blown into the tank 1, and outside air (combustion air) passes through the gap between the wick 9 housed in the wick cylinder 2 and enters the combustion cylinder 3.
When the motor 4 is rotated in reverse during extinguishing the fire, the fan 5a acts as a suction fan, and the unburned gas remaining in the oil tank 1 is sucked into the suction port 8. It is discharged outside the vessel through the chamber 6a. Therefore, when igniting, it has an auxiliary effect at the start of combustion, and when extinguishing, it prevents unburned gas from rising to the combustion tube 3 and discharges it outside the vessel, shortening extinguishing time and suppressing odor generation. It is something.

Also, the operating time of the motor 4 is determined by the timers 11 and 12 in the board.
Since I set it to operate only for a certain period of time, motor 4
It can be used efficiently without having to spend extra time driving.
