The present invention relates to an odor reduction device for a petroleum fan heater, and more particularly, to an odor reduction device for a petroleum fan heater, which is capable of suppressing the smell and discharge noise of unburned gas generated in the early stage of combustion of a petroleum fan heater using a shape memory alloy. will be.

FIG. 1 shows the overall structure of a general petroleum fan heater, and as shown therein, the fuel tank 20, the fuel receiving tank 21, the fuel receiving 22, the filtration device 23, the electronic pump 24, and the like. Fin fuel device unit A, heat detector 26, spark plug 27, pressurized solenoid valve 28, preheat heater 29, preheat detector 30, needle valve 31 with oil level device 25 ), A combustion device section (B) consisting of a combustion air supply pipe (32) and a vaporizer (33), and an air supply device (C) consisting of a combustion blower (34) and a combustion air filter (35). .

The burner head 36, the combustion cylinder 37, and the combustion cylinder cover 37a are sequentially installed above the vaporizer 33 of the combustion device part B, and an oil refinery plate (inside the burner head 36) is provided. 38) is fixed.

When power is applied to the conventional petroleum fan heater having the above-described configuration, fuel is supplied from the fuel device unit A to the combustion device unit B, preheated to a predetermined temperature by the preheat heater 29, and the preheat heater ( 29, when the vaporizer 33 is heated, the preheating sensor 30 senses the temperature, and the combustion blower 34 of the air supply unit C and the electron pump 24 of the fuel unit A are opened. After a certain time, the pressure solenoid valve 28 is operated to enter the ignition process.

On the other hand, the combustion air is sucked by the blower fan 34 and then supplied to the vaporizer 33 through the pressure solenoid valve 28 and simultaneously pumped to the oil level machine 25.

In addition, the fuel is supplied to the electronic pump 24 and the oil level machine 25 through the fuel tank 20, the fuel receiving tank 21, and the filtration device 23 to maintain the oil level at all times.

On the other hand, the air pressurized to the oil level machine 25 by the combustion blower 34 is fueled by the air pressure to the carburetor 33 through the needle valve 31 at this time, the carburetor 33 in the needle valve 31 Since combustion air is pressurized at the periphery of the rod), the fuel is atomized at the moment when the fuel is statically dropped from the tip of the needle valve 31 by the air velocity.

Accordingly, this atomized fuel is instantaneously vaporized by the preheating temperature of the vaporizer 33 and mixed with the compressed air to be fed into the burner head 36 while forming a mixer and to equalize the pressure in the burner head 36. The mixer to be formed is ignited and burned by the discharge flame of the spark plug 27.

However, in the combustion apparatus of the conventional petroleum fan heater as described above, the flame propagation around the burner head due to the ignition of the spark plug is delayed due to the low temperature of the mixer and its surroundings at the beginning of combustion, so that unburned gas is generated in the flame propagation process. , There was a problem such as polluting the indoor air and the discharge noise of the spark plug and the noise of the radio wave generated.

In addition, conventionally, such as Japanese Unexamined Utility Model Publication No. 60-16812, a flame plate mounted on an upper surface of a burner body is pressed by a burner cap made of a storage memory alloy to prevent leakage of unburned gas at the beginning of combustion. Attempts have been made, but in such an apparatus, burner cap made of shape memory alloy is blocked by the flame plate at the beginning of combustion. Therefore, unburned gas is leaked into the flame hole formed in the lower portion of the flame plate at the beginning of combustion, causing odor. In addition, since the primary flame temperature of the flame process during combustion is about 1,000 ℃ to 1,200 ℃, there was a problem such as causing thermal degradation of the shape memory alloy constituting the burner cap.

The present invention has been made in view of the problems of the conventional petroleum fan heater combustion apparatus as described above, the gas opening and closing plate lifting drive means of the gas opening and closing plate is installed in the interior of the combustion cylinder and both sides of the shape memory alloy material By fixing by the gas opening and closing the gas opening and closing plate in accordance with the change in the internal temperature of the vaporizer so that the mixer can be completely burned in the inside of the burner head in the initial stage of combustion, which will be described in detail with reference to the accompanying drawings as follows. .

2 to 5 show the main components of the odor reducing device according to the present invention, as shown in the drawing, the protrusion 1a is formed on the inner wall of the combustion chamber 1 and is inserted into the inner wall. A gas opening plate 2 having a gas hole 2a of a predetermined size is formed in the portion, and a two-way is formed between the corner portion of the gas opening plate 2 and one side of the combustion cylinder 1. It is configured to connect the gas opening and closing plate lifting drive means 10 of the shape memory alloy material of the method.

In the illustrated example, although the tension coil spring is used as the gas opening and closing plate lift driving means 10, it is not necessarily limited thereto, and any shape may be used to lift and move the gas opening and closing plate 2 while being stretched according to temperature. It's okay.

The gas opening and closing plate 2 has a guide groove 2b formed at an outer side thereof, and a ring 2c for connecting to the gas opening and closing drive end 10 is formed at the middle portion thereof.

The gas opening and closing plate lift driving means 10 can be changed in a two-way manner to maintain a relaxed state below a predetermined temperature (t ° C.) and to maintain a compressed state above a predetermined temperature (t ° C.).

The present invention having the above-described configuration burner head (2) by the gas opening and closing plate lifting drive means (10) which is in a relaxed state by its own characteristics when the mixer is introduced into the vaporizer 33 in the same way as the conventional method (burner head ( 36 is in close contact with the upper side of the burner head 36 to form a sealed space surrounded by the outer periphery of the burner head 36 and the lower side of the gas opening and closing plate 2, the mixer is stagnated in the sealed space of the spark plug 27 It is burned by discharge flame.

After the above process, when the temperature of the vaporizer 33 and the combustion cylinder 1 rises above the predetermined temperature (t ° C.), it is compressed by the characteristics of the gas opening and closing plate driving means 10 and mixed in the closed compartment. The mixed mixer and the combustion gas flow out into the room as before through the gas hole 29 of the gas opening and closing plate 2.

At this time, since the combustion gas flowing out into the room is sufficiently burned in a state where the temperature in the vaporizer 33 is raised above a predetermined temperature (t ° C.), the combustion gas is significantly reduced in comparison with the related art.

In addition, when the petroleum fan heater is extinguished, as the temperatures of the vaporizer 33 and the combustion tank 1 are lowered below a predetermined temperature (t ° C.), the gas opening and closing plate lift driving means 10 is relaxed to form a closed space. At the same time, the inflow of gas is stagnated, and unburned gas in the sealed space is completely oxidized and removed as self heat of the gas-opening plate 2 heated during combustion.

The present invention as described above is the temperature of the unburned gas flowing into the room, such as during the initial ignition or extinguishing of the gas opening and closing plate driven by the gas opening and closing plate driving means such as the tension spring of the shape memory alloy material, or less than a predetermined temperature. In this case, as the gas opening and closing driving means of the shape spring alloy tension spring is contracted, the gas opening and closing plate descends to form a closed space, so that the unburned gas flowing into the room can be shut off and completely burned. Not only can it prevent pollution of indoor air, but it can also block high-pressure discharge noise and explosion noise caused by flame propagation of the initial spark plug.
