BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carburetor used in an oil combustor, and more particularly to a mounting device capable of reliably mounting the carburetor with good workability.

[0002]

2. Description of the Related Art A conventional mounting device of this type will be described with reference to FIG. 4. Reference numeral 51 is a burner, 52 is a vaporizer for ejecting vaporized gas from a nozzle 53 to the burner, and 54 is a mounting bracket for mounting the vaporizer 52. One of the mounting brackets 54 is used for the carburetor 5.
The carburetor 52 is properly oriented with respect to the burner 51 by screwing the second and the other to a stand (not shown) or the like.

[0003]

However, in the mounting device described above, if the carburetor 52 is not properly oriented, the emission direction of the vaporized gas and the intake of the primary air accompanying the vaporization of the vaporized gas become poor, resulting in a red fire or Abnormal combustion such as lifting occurs. Therefore, all the combustion inspections are performed at the time of manufacture, and if abnormal combustion occurs, it is corrected by the vertical adjustment screw 55 and the front-back adjustment screw 56, for a total of four.

Thus, although the abnormal combustion equipment can be eliminated by adjusting the direction, the productivity is deteriorated by the adjustment, and when the carburetor 52 is maintained, the repairer is burdened with the adjustment. However, depending on the skill of the repairman, there may be cases where the combustion cannot be adjusted well.

In addition, a needle valve 57 that can move forward and backward to prevent clogging of a hole such as tar is often projected from the nozzle 54. Care should be taken when installing the carburetor 52 so as not to damage the needle valve 57. It had to be done. The present invention has been made in view of the above-mentioned various problems, and an object thereof is to provide a carburetor mounting device that allows anyone to easily and reliably mount the carburetor.

[0006]

In order to achieve the above object, a first invention is a box having a burner and an insertion hole for mounting the burner and positioning a nozzle at a position facing the opening of the mixing tube. And a vaporizer that heats and vaporizes the liquid fuel and ejects it from a nozzle, and a mounting bracket that mounts the vaporizer to the box body. The mounting bracket has a penetrating portion for positioning and a penetrating portion that penetrates the opening of the box body. In this configuration, a penetration limiting portion that limits the penetration depth of the nozzle and an insertion limiting portion that restricts the insertion depth of the nozzle are provided.

The second invention is the same as the first invention,
The nozzle is configured to be located between the penetration part and the insertion restriction part and inside a virtual line connecting the tips of both parts.

A third aspect of the invention is the construction of the first or second aspect of the invention, in which the mounting member is screwed to the box body through a temporary fixing mechanism formed near the insertion restriction portion. Is.

[0009]

According to the first aspect of the invention, by simply moving the mounting member so that the penetrating portion is inserted into the opening of the box body, the nozzle is securely fitted into the insertion hole without damaging the tip, and the insertion restricting portion is used. Since the insertion depth is constant, the carburetor can be easily attached.

According to the second aspect of the invention, in addition to the above-mentioned action, even when the mounting fitting is moved in an inclined posture, the penetration portion and the insertion limiting portion collide first, so damage to the nozzle can be prevented. .

According to the third aspect of the invention, in addition to the above-mentioned respective actions, since the carburetor is already in the temporarily fixed state when screwed, the carburetor can be reliably fixed as it is, and the carburetor of the carburetor can be fixed when the fixing is completed. Since there is almost no deviation in the direction, no adjustment is necessary.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a burner composed of a flame port 2 and a mixing tube 3, and the mixing tube 3 is located inside a box body 4. The box body 4 has an insertion hole 7 for positioning the nozzle 6 and an opening 9 through which the penetrating portion 8 penetrates at a position facing the opening 5 of the mixing tube 3, and a claw piece 10 as a temporary fixing mechanism is formed.

A vaporizer 11 is a heating vaporizer 12 for heating and vaporizing liquid fuel, a nozzle 6 for ejecting vaporized gas, and a solenoid body 14 for advancing and retracting a needle valve 13 penetrating the nozzle 6.
Equipped with each. The needle valve 13 slightly projects from the tip of the nozzle 6 as shown in the enlarged view of FIG.

Reference numeral 15 is a mounting metal fitting for mounting the carburetor 11 on the box body 4, and a penetrating portion 8 for positioning and a penetrating limiting portion 16 for limiting the penetrating depth of the penetrating portion 8 are formed at one end thereof.
An insertion limiting portion 17 that limits the insertion depth of the nozzle 6 and a square hole 18 with which the claw piece 10 meshes are formed at the other end.

As shown in FIG. 3, the nozzle 6 is located between the through portion 8 and the insertion limiting portion 17 and inside the imaginary line (dotted line in FIG. 3) connecting the tips of both portions.

In order to attach the carburetor 11 to the box body 4 in the above-described structure, first, the mounting member 15 to which the carburetor 11 is attached is held and the penetrating portion 8 is moved with the opening 9 as a target. After that, when the penetrating portion 8 starts to penetrate the opening 9, at the same time, the movement of the nozzle 6 is restricted all at once, and the nozzle 6 accurately enters the insertion hole 7. Finally, the penetration limiting portion 16 and the insertion limiting portion 17 come into contact with the box body 4, and with this, the insertion of the nozzle 6 to a predetermined insertion depth is completed.

As described above, the carburetor 11 can be attached to the box body 4 by a simple operation of moving the penetrating portion 8 toward the opening 9, and the nozzle 6 is penetrated from immediately before entering the insertion hole 7. As the range of movement affected is limited,
It is possible to effectively prevent the needle valve 13 from colliding with and damaging the wall surface of the box body 4.

To prevent damage to the nozzle 6 described above,
Since the nozzle 6 is located between the penetrating portion 8 and the insertion limiting portion 17 and is located inside a virtual line connecting the tips of both portions,
A better effect can be expected. Because the mounting bracket 15
This is because the penetrating portion 8 and the insertion limiting portion 17 collide with the wall surface or the like before the needle valve 13 in this case.

Next, as described above, at the time when the insertion of the nozzle 6 is completed to the predetermined depth, the claw piece 10 and the square hole 18 mesh with each other, and the penetrating portion 8 penetrates the opening 9 according to the procedure. Combined with this, the carburetor 11 is in a temporarily fixed state. In this temporarily fixed state, the square hole 18 and the screw hole in the vicinity of the claw piece 10 are substantially aligned with each other, so that the screw hole can be screwed as it is,
Even if there is a hole shift, it can be easily corrected.

From the above, the carburetor 11 is finally obtained.
Since the mounting screw does not necessarily have to be provided on the penetrating portion 8 side when fixing the box to the box body 4, the number of screws is smaller than in the conventional case, workability is improved, and the carburetor 11 is provided.
Is correctly attached as specified, and the orientation is unlikely to occur, so that it is not necessary to adjust the combustion state.

[0021]

As described above, according to the present invention, by simply moving the penetrating portion with the opening of the box as a target, the nozzle can be securely and easily brought to a predetermined insertion depth without damaging the tip. Since it can be inserted into the insertion hole, the work of attaching the carburetor can be performed easily.

Further, since the nozzle is located between the penetrating portion and the insertion limiting portion and inside the imaginary line connecting the tips of these portions, even if the mounting metal fitting is moved in an inclined posture when the carburetor is mounted, It is possible to prevent damage to the tip of the nozzle.

Further, since the mounting member is constructed so as to be screwed to the box body through the temporary fixing mechanism formed near the insertion restriction portion,
Since the carburetor is easily fixed and installed in a predetermined manner to cause almost no misdirection, the adjustment of the combustion state can be dispensed with.
