Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid vaporization type combustion device used as an oil fan heater or the like.

[0002]

[Prior Art]

 An oil fan heater is used as an example of a conventional liquid vaporization type combustion apparatus, and will be described with reference to FIG.

A combustion chamber 2 in which a burner 6 for burning petroleum 9 which is a liquid fuel is installed inside the main body 1, and indoor air 17 is sucked into the main body 1 inside the main body 1 and blown out to the outside of the main body 1 The convection blower 3 and the louver 4 for blowing out the warm air 19 in which the indoor air 17 from the blower 3 is mixed with the combustion gas 18 burned by the burner 6 in the combustion chamber 2 are provided on the front surface of the main body 1. The installed hot air outlet 5 is provided.

Next, a combustion part for burning the burner 6 will be described with reference to FIG.

The combustion section includes a fuel tank 8 for storing the oil 9 sent from a cartridge tank 7 containing the oil 9 through a valve, and a fuel pump 10 for pumping the oil 9. A vaporizer 12 for vaporizing the petroleum 9, an oil feeding pipe 11 for feeding the petroleum 9 pumped by the fuel pump 10 to the vaporizer 12, and a petroleum 9 vaporized in the vaporizer 12 It comprises a nozzle 13 provided in the vaporizer 12 for jetting, a burner 6 for burning the petroleum gas 16 supplied by the nozzle 13, and an ignition device 14 connected to a power source. Further, the burner 6, the carburetor 12, the nozzle 13, and the ignition device 14 are provided inside the combustion chamber 2.

By setting the cartridge tank 7 containing petroleum 9 in the fuel tank 8, the petroleum 9 flows from the cartridge tank 7 into the fuel tank 8 through the valve, Oil 9 collects in the. The oil 9 is sucked up by the fuel pump 10 and sent to the vaporizer 12 through the oil feed pipe 11. The petroleum 9 sent into the vaporizer 12 is vaporized, and a petroleum gas 16 is ejected from a nozzle 13 provided in the vaporizer 12 to mix with the combustion air 15 and a burner 6 ignited by an ignition device 14 Burn with. The combustion gas 18 combusted in the burner 6 is mixed with the indoor air 17 sent from the convection blower 3 in the upper part of the combustion chamber 2 to become warm air 19 which is blown out from the warm air outlet 5.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional oil fan heater, when the hot air outlet is closed or becomes small due to an obstacle such as laundry or a container, the indoor air from the convection blower and the combustion gas burned by the burner are separated. Since there is no place where the mixed hot air is blown out and it stays in the main body, the hot air flows back into the combustion chamber and pressure is applied, resulting in insufficient air combustion and incomplete combustion may occur.

An object of the present invention is to provide a liquid vaporization type combustion device which performs stable combustion without incomplete combustion.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a liquid vaporization provided with a combustion chamber having a burner and a carburetor installed therein, a convection blower for taking in and blowing out indoor air, and a hot air outlet provided with a louver. In the combustor, a combustion gas delivery duct is provided so as to connect the upper part of the combustion chamber to the intake side of the convection blower in order to blow out the combustion gas burned by the burner to the convection blower.

[0010]

[Action]

 By installing a combustion gas delivery duct so that the combustion gas is delivered from the upper part of the combustion chamber to the intake side of the convection blower, the combustion gas is once sucked into the convection blower and mixed with the room air and heated from the hot air outlet. It is blown out as a wind. As a result, even if the hot air outlet is closed by an obstacle or becomes small and there is no place for the hot air to blow out, the hot air will not directly flow back into the combustion chamber and apply pressure, so air shortage combustion Incomplete combustion does not occur.

【Example】

 An embodiment according to the present invention will be described below with reference to the drawings using an oil fan heater.

FIG. 1 is a sectional view of a liquid vaporization type combustion apparatus of the present invention. FIG. 2 is a sectional view showing a conventional combustion section. The same parts as those in the conventional technique are designated by the same reference numerals.

The liquid vaporization type combustion apparatus of the present invention includes a combustion chamber 2 in which a burner 6 for burning petroleum 9 which is a liquid fuel is installed inside a main body 25, and indoor air 17 on the back surface of the main body 25. A convection blower 3 for sucking air into the main body 25 and blowing it out of the main body 25, and a warm air 19 formed by mixing the combustion gas 18 from the combustion chamber 2 and the indoor air 17 from the blower 3 on the front surface of the main body 25 for blowing out A hot air outlet 5 having a louver 4 is provided.

Further, since the combustion gas 18 burned in the combustion chamber 2 is directly delivered to the convection blower 3, the combustion gas delivery duct 20 is provided so that the upper part of the combustion chamber 2 and the intake side of the convection blower 3 are communicated with each other. Is provided.

Next, since the burner for burning the burner 6 is exactly the same as that of the prior art, detailed description thereof will be omitted.

By setting the cartridge tank 7 containing petroleum 9 in the fuel tank 8, the petroleum 9 flows from the cartridge tank 7 to the fuel tank 8 through the valve, and the fuel tank 8 Oil 9 collects in the. The oil 9 is sucked up by the fuel pump 10 and sent to the vaporizer 12 through the oil feed pipe 11. The petroleum 9 sent into the vaporizer 12 is vaporized, and the petroleum gas 16 is ejected from the nozzle 13 provided in the vaporizer 12 to mix with the combustion air 15 and the burner 6 ignited by the ignition device 14 is ejected. Burn with.

The combustion gas 18 combusted by the burner 6 is delivered to the intake side of the convection blower 3 through the combustion gas delivery duct 20, and is mixed with the indoor air 17 in the convection blower 3 to generate hot air 19. It is blown out from the wind outlet 5.

[0018]

[Effect of the device]

 As described above, the liquid vaporization type combustion device of the present invention is provided with the combustion gas delivery duct so as to connect the upper part of the combustion chamber and the intake side of the convection blower, so that the combustion chamber has a close-closed structure and washing. Even if the hot air outlet is closed or made smaller by an obstacle such as an object or a curtain, the hot air from the convection blower flows backward and directly enters the combustion chamber, and no reverse pressure is applied.

As a result, the combustion air is stably supplied to the combustion chamber, the insufficient air combustion is eliminated, and the incomplete combustion does not occur.

Further, since the combustion gas is once sent to the convection blower and mixed with the room air, it is possible to stably blow hot air of uniform temperature from the hot air outlet.

Further, since the combustion gas is absorbed in the convection blower, the supply of the combustion air is further improved, the pressure is increased, and the opening of the hot air outlet can be reduced.
