Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a driving device for an ignition heater for an oil combustor.

[Conventional technology]

Conventional oil combustor ignition systems perform a series of operations in which an opening is created by lifting a combustion tube or moving an ignition door, an ignition heater is moved to the opening to ignite a combustion wick, and then the opening is closed. For this reason, in the past, bearings were installed in each of the operating lever for manual operation, the igniter drive plate for moving the ignition door, the ignition arm for moving the ignition heater, etc., and the components were arranged in an interlocking relationship. It was hot.

[Problem that the invention attempts to solve]

Many of the parts constituting the ignition system rotate around bearings, and the installation of these bearings complicates the manufacturing process and increases costs.

[Means for solving problems]

This invention relates to an ignition heater drive device that can be easily manufactured mainly by fitting together without using any special tools. 1 is an igniter base that is fixed to the wick housing tube of an oil burner with screws; 3 is an operating lever with an operating knob 10 attached to its tip, and the operating lever 3 and base 1 have a bearing 2 formed by a protrusion 2' and a hole 2''.The protrusions 2' and 2'' are used for normal ignition. It can be fitted at a position away from the operating range in which it moves during operation, and within the operating range, the end of the convex portion 2' is engaged with the hole 2'' to prevent it from coming off.

6 is an igniter drive plate for operating the ignition door 11 and the combustion tube; 5 is a long hole formed in the igniter drive plate 6; 4 is a protrusion that is attached to the base 1 and fits into the long hole 5; The corresponding elongated hole 5 is long, and the positional relationship between the elongated hole 5 and the protrusion 4 is moved away from the range of movement of the igniter drive plate 6 in which the igniter drive plate 6 slides along the elongated hole 5 during normal ignition operation. When rotated, the protrusion 4 can be fitted into the elongated hole 5 as it is in the fixed position. Therefore, when the igniter drive plate 6 slides through the normal movement range, the end of the protrusion 4 engages with the elongated hole 5 and comes off. I try not to.

Further, the driving end 3' of the operating lever 3 is engaged with the igniter driving plate 6, and when the operating lever 3 is rotated, the igniter driving plate 6 moves while the elongated hole 5 and the projection 4 are engaged. As a result, the engagement range between the elongated hole 5 and the protrusion 4 becomes the movement range of the igniter drive plate 6, and the operation range of the operating lever 3. Further, similar to the engagement between the protrusion 4 and the elongated hole 5, the engagement between the igniter drive plate 6 and the operating lever 3 can be made at a position outside the normal movement range of the igniter drive plate 6.

8 is an ignition arm; 9 is an ignition heater attached to the tip of the ignition arm 8; the other end 8' of the ignition arm 8 without the ignition heater 9 is engaged with the igniter drive plate 6; 8 is rotatably attached to the base 1 by a mounting shaft 7. Further, it is preferable to use a part that can be manually installed, such as a stop ring, to hold the mounting shaft 7.

Therefore, the ignition heater 9 and one end 8' of the ignition arm 8 are designed to rotate around the mounting shaft 7, and when the igniter drive plate 6 is moved by the operating lever 3, the one end 8' of the ignition arm 8 is rotated. via ignition arm 8
rotates, and the ignition heater 9 approaches a wick (not shown). At this point, the movable range of the igniter drive plate 6 is determined by one end 8' of the ignition arm, so the igniter drive plate 6 is positioned at a position where the elongated hole 5 and the protrusion 4 as well as the igniter drive plate 6 and the operating lever 3 are disengaged. 6 becomes unable to move.

[Explanation of action]

In this invention, which has the above-mentioned configuration, the base 1 and the bearing part 2 of the operating lever 3 are fitted together, and the igniter drive plate 6 is removed from the normal position with respect to the base 1, and the protrusion 4 of the base 1 and the elongated hole are connected to each other. 5 and the igniter drive plate 6 and the operation lever 3, and then return the igniter drive plate 6 to its normal position, the protrusion 4 and the elongated hole 5 and the igniter drive plate 6 and the operation lever 3 will be connected. It can be engaged.

Next, connect one end 8' of the ignition arm 8 to the igniter drive plate 6.
The ignition arm 8 is attached to the base 1 with the mounting shaft 7 while engaging with the
If the igniter drive plate 6 is attached to the ignition arm 8, which rotates around the attachment shaft 7, the movement of the igniter drive plate 6 will be restricted by the ignition arm 8, and the igniter drive plate 6 will not be able to move to a position where the protrusion 4 and the elongated hole 5 are removed. .

Therefore, if the ignition heater drive device of this invention is fixed to the oil combustor main body with screws or the like, the ignition door can be opened by operating the operating lever, and the ignition heater can be brought close to the wick and ignited.

[Explanation of effects]

As described above, in this invention, the operating lever 3 and igniter drive plate 6 that are attached to the base 1 are attached by simple fitting, and only the ignition arm 8 is attached to the base 1 with the attachment shaft 7, so the assembly process is extremely simple. Moreover, parts can now be easily manufactured by press working.

Also, unlike the conventional system which uses many rotating shafts, the final assembly requires only a single mounting shaft for mounting the ignition arm, making it possible to significantly reduce costs.
