Abstract

PURPOSE:To suppress pulsating combustion and enable stable combustion by mounting a tube member to the inside of a fuel feed pipe contiguous to a connection with a vaporizing chamber so as to be contacted with the inner wall of said pipe and connected to a mesh member of the vaporizing chamber. CONSTITUTION:A mesh member 60 is mounted to a vaporizing chamber 31, and the top end of a fuel feed pipe 20 is connected to the uppermost part of the vaporizing chamber 31. A tube member 70 is mounted to the inside of the fuel feed pipe 20 so as to be contacted with the inner wall of said pipe contiguous to a connection with the vaporizing chamber 31, and this tube member 70 abuts against the mesh member 60. Since the sectional area of the fuel passage is decreased at a portion where the tube member 70 of the fuel feed pipe 20 is mounted, the flow rate of kerosene fed by the operation of an electromagnetic oil pump 10 is accelerated, and the kerosene in the accelerated state is sent into the vaporizing chamber 31. Thereby, a period of time during which the kerosene in the fuel, feed pipe 20 is heated with heat generated from a carburetor 30 is reduced. That is, the kerosene is fed into the vaporizing chamber 31 without being much heated in the fuel feed pipe 20, and the vaporization of the kerosene, which may take place the moment the kerosene enters the vaporizing chamber 31, is suppressed. Accordingly, even in the case where the amount of kerosene to be fed is reduced, pulsating vaporization is suppressed and pulsating combustion is also suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an oil vaporization device used, for example, in an oil hot air heater or other oil burner.

<Conventional technology and its issues> Conventionally, in vaporizers such as oil hot air heaters, in order to reduce the power consumption of the heater for vaporizing oil, a heat receiving part is installed in the vaporizer, and a part of the combustion heat is used for vaporization. I'm trying to heat the container.

However, when the oil input to the vaporizer (oil supply amount) decreases while the vaporizer is being heated to a high temperature by the combustion heat, the oil is warmed in the oil pipe that sends oil to the vaporizer, and the oil is heated up in the vaporizer. When it enters the oil, it is instantaneously vaporized, resulting in a pulsating combustion that matches the frequency of the oil pump.

SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and provides an oil vaporizer that does not cause pulsating combustion, such as instantaneous vaporization of oil that enters the vaporizer, even when the oil input to the vaporizer is small. With the goal.

Means for Solving the Problems> In order to achieve the above object, the oil vaporizer of the present invention has a heat receiving part that receives combustion heat in the combustion part in addition to the heating heater, and the oil vaporizer has a heat receiving part that receives combustion heat in the combustion part, An oil vaporizer that gasifies delivered oil in an internal vaporization chamber and sends it to a combustion section, wherein a mesh body is installed in the vaporization chamber and the oil feed pipe is connected to the vaporization chamber. The present invention is characterized in that a cylindrical body is installed inscribed in the pipe following the section and continuous with the mesh body in the vaporization chamber.

<Function> By installing a cylindrical body that is continuous with the mesh body in the oil transmission pipe, the cross-sectional area inside the oil transmission pipe is reduced at the part where the mesh body is installed, so that the flow rate of the oil being sent increases in that part and vaporizes. sent into the vessel. In other words, since the flow velocity in the oil pipe near the vaporizer becomes faster, the heating of the oil in the oil pipe is reduced accordingly, and it is suppressed that the oil is vaporized the moment it enters the vaporization chamber. Therefore, pulsating vaporization that matches the frequency of the oil pump is suppressed, and pulsating combustion is suppressed as a whole.

<Embodiment> FIG. 1 is a block diagram of an apparatus for implementing the present invention, and FIG. 2 is an enlarged view of the main parts.

From the electromagnetic oil pump 10 to the carburetor 3 through the oil pipe 20
Oil is sent to the tank 0 and vaporized in a vaporization chamber 31 inside. The vaporized petroleum is sent from the nozzle 32 to the combustion tube 40, where it is subjected to combustion.

A heater 50 is attached to the vaporizer 30. Further, the upper end of the carburetor 30 serves as a heat receiving portion 33 for receiving combustion heat generated by combustion in the combustion tube 40. 34 is a needle valve of the nozzle 32, 35 is a solenoid, 36 is a return pipe, and 37 is a temperature sensor.

A mesh body 60 is attached to the vaporization chamber 31.

This mesh body 60 can be made of, for example, a wire mesh wound around it. The tip of the oil feed pipe 20 is connected to the top of the vaporization chamber 31. A cylindrical body 70 is attached to the oil pipe 20 so as to be inscribed in the pipe that continues to the connection part with the vaporization chamber 31 . This cylindrical body 70 is provided so as to come into contact with the mesh body 60. The cylinder 70 can be made of metal or other materials.

The oil sent by the electromagnetic oil pump 10 is sent into the vaporization chamber 31 at an increased flow rate by reducing the substantial passage cross-sectional area at the portion of the oil pipe 20 where the cylinder 70 is attached. . Therefore, the time during which the oil is heated in the oil pipe 20 by heat from the vaporizer 30 side is shortened. That is, the oil can enter the vaporization chamber 31 without being heated much within the oil pipe 20. Therefore, the oil is prevented from being vaporized the moment it enters the vaporization chamber 31. Therefore, even when the oil input is reduced, pulsating vaporization is suppressed and pulsating combustion is suppressed.

<Effects> The present invention has the above configuration, and according to the oil vaporizer according to claim 1, the oil vaporizer is inscribed in the pipe of the oil feed pipe following the connection part with the vaporization chamber, and is continuous with the mesh body of the vaporization chamber. Since the cylindrical body is installed, the flow rate of oil from the oil pipe to the vaporization chamber increases,
As a result, even in the case of a small input, pulsating vaporization in the vaporization chamber is suppressed, and as a result, pulsating combustion is suppressed and stable combustion can be performed.
