Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a vaporizer that is used in an oil heater and heats and vaporizes supplied oil.

<Prior art and its problems> First, an outline of a kerosene heater will be explained with reference to FIG. Petroleum, which is a combustion material, is discharged and supplied through a pipe 1 from the vicinity of a rotor 3 rotated by a motor 2 to a vaporization chamber 14 side. This supplied oil is in the vaporization chamber 14.
Inside, the water is atomized by the blades 4 attached to the rotor 3, and heated and vaporized by the heat from the vaporizer 10. The vaporized oil is sent to the combustion tube 5 together with the supplied air and burned.
6 is a radiation plate. A part of the generated heat is transferred to the heat collector 7
The heat is collected by the vaporizer 10, and the heat is conducted to the vaporizer 10 side.
It is used for heating the vaporizer 10.

A conventional vaporizer that uses a portion of the heat generated by combustion for heating itself is a vaporizer shown in FIG. 4. This vaporizer is code 20
Expressed as The vaporizer 20 includes a vaporizing section 21, a mounting section 22 for the heat collector 7, and a heat conduction section 23 continuous from the mounting section 22 to the vaporizer 20. Vaporization chamber 2
4 is formed in the inner hole 21a of the vaporizing section 21 of the cylindrical body. 21b is an insertion hole through which the rotor 3 is inserted. In the case of such a conventional vaporizer 20, the heat conduction part 2 extending from the heat collector mounting part 22
3 is connected to or continuous with only one part of the upper part of the vaporizing part 21, so the vaporizing part 21 has a drawback that temperature unevenness tends to occur between the upper part and the lower part. That is, the upper part of the vaporizing part 21 to which the heat conducting part 23 is connected tends to be overheated, and the lower part of the vaporizing part 21 tends to be under-temperature, so the disadvantage is that the range in which good vaporization can be performed is narrow. It was hot.

Therefore, the present invention solves the drawbacks of the above-mentioned conventional technology,
The purpose of the present invention is to provide a vaporizer that is less likely to cause temperature unevenness and has good and stable vaporization performance.

<Means for Solving the Problems> In order to solve the above problems, the present invention improves the shape of the heat conduction part and the connection to the vaporization part. That is, the vaporizer for an oil heater according to the present invention is a vaporizer for an oil heater that atomizes the supplied oil and vaporizes it to send it to the combustion section, and the vaporizer is a vaporizer for an oil heater that is configured to have a cylindrical body. a vaporizing section having a vaporizing chamber configured in an inner hole thereof; a heat collector mounting section for mounting a heat collector for collecting heat from the combustion section; and a heat collector mounting section connecting the heat collector mounting section and the vaporizing section. The metal body includes a heat conduction part that conducts the heat of the heat collector to the vaporization part, and the heat conduction part is divided into two parts, and the divided heat conduction part is connected to the side peripheral part of the cylindrical body. It is characterized by being divided evenly on both sides and connected.

<Function> Since the heat conduction part is evenly divided and connected to the side circumference of the cylindrical body that constitutes the vaporization part, heat from the heat collector is transmitted to the vaporization part from both sides, and even heating is performed. . Since the heat conduction section is divided and connected to the vaporization section, the efficiency of heat conduction is high.
The vaporization chamber is heated evenly from its surroundings to ensure efficient vaporization.

<Example> FIG. 1 shows a front view of a vaporizer showing an example of the present invention, and FIG. 2 shows a left side view thereof.

The vaporizer 10 has a vaporization chamber 1 in an inner hole 11a of a cylindrical body.
4, a heat collector attachment part 12 to which the heat collector 7 is attached, and a heat conduction part 13 for conducting heat from the heat collector attachment part 12 to the vaporization part 11 are integrally molded. Made of metal. The vaporizer 11 is configured as a cylindrical body with a bottom, and the rotor 3 is attached to the bottom of the cylindrical body.
A through hole 11b for insertion is formed. The heat conduction portion 13 is divided into two parts, and the heat conduction portions 13, 13 are connected to both sides of the cylindrical body of the vaporization portion 11 at substantially equal intervals. Therefore, the heat from the heat collector 7 moves to the vaporization section 11 as shown by arrows in FIG. 1, and evenly heats the vaporization chamber 14 from the surrounding area. The center part of the heat conduction part 13 is a space S
Therefore, the heat from the heat collector 7 is efficiently conducted to both sides of the side circumferential portion of the vaporizing portion 11 through the bifurcated heat conducting portions 13, 13.

<Effects> The present invention has the above-mentioned configuration, and the heat conduction part is divided and connected to the side circumference of the cylindrical body constituting the vaporization part so as to be divided evenly, so that the heat is collected. Heat is evenly conducted to the vaporizer. As a result, the vaporization chamber can be heated evenly from the surrounding area, resulting in the following effects.

Since there is little temperature unevenness in the vaporizing section, the entire body can be heated to an appropriate temperature with relatively little heat collection. This has the effect that the vaporization chamber can be quickly heated to a predetermined temperature even during weak combustion operation.

It is possible to prevent the Leidenfrost phenomenon from occurring.
The Leidenfrost phenomenon is a phenomenon that conversely causes poor vaporization when the vaporization surface becomes overheated. However, in this invention, the temperature of the entire vaporization section is raised evenly, so even during strong combustion operation, partial overheating can be prevented. This is because it cannot be caused to occur.

Furthermore, since the heat conduction section is divided, heat is efficiently conducted in a predetermined direction, resulting in good thermal efficiency.
