Description

  The present invention relates to a combustion apparatus that is resistant to silicone oxide generated by burning silicone contained in cosmetics and the like.

  Conventionally, this type of combustion apparatus has three electrode means, and when the burner is burning normally, the potential difference between one potential of the flame and the burner is detected between the two points of the flame. The obtained potential difference is theoretically determined, and the obtained potential difference is compared with the potential difference detected between one potential of the flame and the burner to determine and control the combustion state. (For example, refer to Patent Document 1.)

  By the way, in this conventional type, on the assumption that most of the silicon oxide adheres to and accumulates on the frame rod, the number of frame rods is increased in order to accurately detect this in the state where the silicone oxide has adhered and deposited. It is necessary to replace the frame rod to which the silicon oxide is attached, and it is very uneconomical.

  In order to solve the above-mentioned problems, the present invention is particularly configured as claimed in claim 1, a combustion burner for receiving a supply of combustion fuel and combustion air to form a flame and burning it, and passing a current through the flame to increase its size. In addition, a frame rod that monitors the combustion state is provided with a filter that adsorbs silicone in the combustion air in the combustion air supply path.

  According to the present invention, the filter for adsorbing the silicone in the combustion air is provided in the supply path of the combustion air, so that the silicone is supplied to the combustion burner together with the combustion air and does not become a silicone oxide. There is no worry about adhesion to the flame, that is, it is a completely new idea to remove the silicone before it becomes silicone oxide from the combustion air, not how to detect the adhesion of silicone oxide to the frame rod Since the silicone is removed, it is not necessary to replace or add a frame rod, improve the control circuit, etc., and it is extremely economical and easy to use.

  According to the second aspect of the present invention, since the filter is composed of an activated carbon filter, it can reliably adsorb silicone and can also adsorb odor molecules to reduce odor.

  According to the third aspect of the present invention, since the filter has fine pores into which silicone molecules are fitted by an activated carbon filter, the silicone molecules can be reliably adsorbed to the fine pores and maintained for a long time without separation. It is possible.

  According to the fourth aspect of the present invention, since the filter is detachably attached to the suction port of the supply path with an activated carbon filter, the state of the activated carbon filter can always be easily grasped and replaced easily.

Reference numeral 11 denotes a trumpet-shaped collecting plate that partitions the vaporizing cylinder 1 and the combustion burner 6. After the air-fuel mixture is once collected at a portion suspended in the vaporizing cylinder 1, it diffuses to promote mixing and It suppresses the flow rate.

12 is a rectified cylindrical flow straightening tube provided on the collecting plate 11, and has a plurality of flow straightening holes 13 on the upper side, and flows into the flame hole 7 of the combustion burner 6 while straightening the inflowing air-fuel mixture. It is a guide.
Reference numeral 14 denotes a combustion fan comprising a turbo fan that supplies combustion air to the vaporizing cylinder 1, and supplies the indoor air sucked from the suction port 15 into the vaporizing cylinder 1 from the blower port 5 through the supply path 16.

  17 is an activated carbon filter constituting a filter that is detachably attached to the suction port 15 that is the inlet of the supply path 16, and is formed by impregnating activated carbon into a base material in which glass fibers are entangled with paper (pulp). Then, a plurality of ventilation holes 18 are formed, the activated carbon has innumerable fine holes 19, and the hole diameter is 0.1 to 0.3 nanometer into which the silicone molecule A is fitted, and the thickness is 15 mm as a whole. It is what you have.

Reference numeral 20 denotes an oil feed pipe for supplying fuel oil pumped by the electromagnetic pump 21 into the vaporizing cylinder 1, and a spray nozzle 4 protruding into the vaporizing cylinder 1 is provided at the tip thereof.
A fixed tank 22 is connected to the other end of the oil feeding pipe 20 and temporarily stores fuel oil supplied from a cartridge-type oil supply tank 23 via a valve mechanism 24. The fuel oil amount is detected, and the fuel oil is supplied below a predetermined amount. A float type oil supply detecting means 25 for informing and a filter cylinder 26 for preventing the inflow of dust into the oil feeding pipe 20 are provided.

Next, the operation of the embodiment of the present invention will be described.
By performing a known operation, the heater 2 is energized to raise the temperature of the vaporizing cylinder 1 to a preset vaporizable temperature.

  When the vaporizing cylinder 1 reaches the set temperature, the temperature sensor 3 detects this and activates the combustion fan 14, the electromagnetic pump 21, and the ignition electrode 9, respectively.

  As a result, the combustion fan 14 supplies the combustion air into the vaporizing cylinder 1 from the air blowing port 5 through the supply path 16, and the fuel oil is vaporized from the spray nozzle 4 through the oil feed pipe 20 by driving the electromagnetic pump 21. The fuel oil is instantly vaporized in the vaporizing cylinder 1 and premixed with the combustion air to form a premixed gas.

  Then, the premixed gas flows into the upper flow straightening cylinder 12 in a state where the flow velocity is suppressed while passing through the collecting plate 11 and performing collection and diffusion, and the premixed gas is further mixed in the flow straightening cylinder 12. After being sufficiently accelerated and rectified through the rectifying hole 13, it is ejected from the flame hole 7 of the combustion burner 6, ignited by the ignition electrode 9, and premixed and combusted.

  Further, in this combustion, combustion air, which is room air flowing from the suction port 15 of the supply passage 16 by driving of the combustion fan 14 passes through the activated carbon filter 17 provided in the suction port 15, so that When hair spray or the like is used and the silicone molecule A is floating in the room, the silicone molecule A fits into the micropores 19 of the activated carbon filter 17 and is removed by adsorption, thereby removing the silicone. Since only combustion air is supplied to the combustion burner 6, there is no generation of silicone oxide itself and no adhesion and deposition on the frame rod 10, so that the frame rod 10 can always reliably detect the combustion state of the combustion burner 6. Is.

  The activated carbon filter 17 adsorbs the odorous molecules B in the combustion air at the same time as the silicone, so that it is possible to reduce the odor in the room. However, since this odor is also adsorbed and removed by the activated carbon filter 17, it has an effect that good combustion without odor can be obtained even with a vaporization type combustion appliance.

  This activated carbon filter 17 can be used for 10 heating seasons and does not deteriorate the adsorption performance, so it is the same as the product life of 10 years and is discarded at the same time without replacement. Further, the activated carbon filter 17 is provided in the suction port 15 of the combustion air supply path 16 and is detachable. When grasping the state, the activated carbon filter 17 can be easily removed and the whole can be seen, and the amount of adsorption should be large. Even when it is replaced in the middle, it can be replaced very easily. However, the activated carbon filter 17 is not limited to the suction port 15, and exhibits the same effect regardless of where it is provided in the supply path 16. It is.

  As described above, in the present invention, even if silicone oxide has been adhered and deposited on the frame rod 10, silicone that has been devised so as to be able to detect the combustion state accurately is removed from the combustion air. In the first place, it is a new idea that it does not generate silicone oxide, and it can detect the combustion state accurately even in a room where silicone floats, with an extremely simple configuration of having an activated carbon filter 17. .
