Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention relates to an oil combustion device, and relates to an improved structure for igniting a combustion wick.

(Prior art) Conventionally, in oil combustion equipment, for example,
As described in Publication No. 12742, the combustion wick is ignited by lifting the combustion cylinder from the fire pan, moving the ignition heater, and bringing the ignition heater closer to the combustion wick. There is.

For example, as described in Japanese Utility Model Application No. 57-46262, a heater body having an ignition heater facing the combustion wick of the fire pan is provided on a combustion cylinder body placed on the fire pan of the wick guide. An oil combustion device is known in which a cord for connecting to a power source is connected to the heater body.

(Problem that the invention attempts to solve) However, when igniting this conventional combustion wick,
In a structure in which the combustion cylinder is lifted from the fire pan and the ignition heater is moved, the combustion cylinder is lifted to expose the combustion wick in the fire pan, which causes an excess supply of air when the ignition heater ignites, which prevents soot from forming. In addition, since the combustion cylinder is moved every time ignition occurs, there is a problem in that it is necessary to adjust the placement of the combustion cylinder with respect to the fire pan.

In addition, in a structure in which the advancement of the combustion wick into the fire pan and the ignition of the ignition heater against the combustion wick are performed by the same lever operation, a large operating force is required because lifting the combustion cylinder and moving the ignition heater places a load. There is a problem.

Furthermore, in a vertically elongated burner, when the combustion cylinder is lifted, the combustion cylinder tends to hit the reflection plate, so there is a problem in that it is necessary to set a large distance between the combustion cylinder and the reflection plate.

In addition, in the structure described in the above-mentioned Japanese Utility Model Publication No. 57-46262, in which the ignition heater is attached to the combustion cylinder, a cord for power connection is connected to the heater body attached to the combustion cylinder, and the combustion cylinder is The cord is connected when attaching and detaching the device, resulting in poor handling and operability.

This idea was created in view of the above problems.
To ignite the combustion wick, the combustion wick can be ignited without moving the ignition heater attached to the combustion cylinder, and the combustion cylinder does not need to be connected to a cord that connects the ignition heater to a power source, and the above-mentioned The purpose of this invention is to provide an oil combustion device that solves various conventional problems.

[Structure of the idea]

The sides thereof are elastic connecting pieces that can be elastically deformed in the vertical direction, and the pair of heater terminals are arranged opposite to the pair of precursor connecting terminals so that each of the pair of connecting terminals can be elastically deformed in the vertical direction. It is arranged so as to protrude from the bottom surface of the heater.

(Function) In the oil combustion device of the present invention, when the combustion cylinder is installed on the fire pan of the wick guide cylinder, a pair of heater terminals protruding from the lower surface of the heater body attached to the combustion cylinder are connected to the wick. A pair of connecting terminals, one end of which is fixed to an insulating plate attached to one side of the upper surface of the core guide cap attached to the upper side of the guide tube, are connected to the elastic connecting piece on the other end of the combustion tube. The elastic connection pieces are pressed downward against the elasticity of the elastic connection pieces due to their weight, and the pair of heater terminals are respectively connected to the pair of connection terminals. In this jam, the pair of connection terminals are electrically connected to the power source, and the ignition heater of the heater body is located at the ignition position of the combustion wick of the fire pan.When the ignition operation is performed, the power source is connected to the ignition heater and the power is energized to ignite it.

In the above, within the range where the locking recess 23 of the guide disk 21 is locked with the positioning metal fitting 10, that is,
Since it can be rotated within the width of the locking recess 23, by rotating the combustion cylinder body 14 and changing the position of the ignition heater 28, the ignition position of the combustion wick 4 relative to the ignited part 13 can be easily adjusted. By adjusting the ignition position, the ignited part 13 can be changed to
Even if one part is burnt out, the ignition heater 28 faces the other part of the ignited part 13 that is not burnt out,
The combustion wick 4 can be ignited.

Next, in the embodiment described above, the heater body 26 is fixed to the inner flame cylinder 15 of the combustion cylinder body 14, but the structure is not limited to this.
may be fixed to an appropriate position of the combustion cylinder body 14, for example, to the outer flame cylinder 16. In this case, the position of the connecting device 48 of the core guide cylinder 1 may be changed in accordance with the changed position of the heater body 26 on the outer flame cylinder 16 side.

[Effect of idea]

According to the present invention, the heater body is detachably attached to the combustion cylinder, and the connection terminal to which the heater terminal of the heater body is connected is placed inside the upper part of the wick guide cylinder having the fire pan on which the combustion cylinder is placed. The pair of connection terminals are provided on an insulating plate attached to one side of the upper surface of the core guide cap that is attached to the core guide cap, and each of the pair of connection terminals has one end on the power connection side fixed to the insulating plate, and also connects to the heater terminal of the heater body. Since the other end that is in contact with the wick is made into an elastic connecting piece that can be elastically deformed in the vertical direction, the heater body attached to the combustion cylinder can be attached to the combustion cylinder while the combustion cylinder is placed on the fire pan of the wick guide cylinder. A pair of heater terminals protruding from the bottom surface of the wick guide cap have one end fixed to an insulating plate attached to the core guide cap. The heater terminal is pressed downward against the elasticity of the connecting piece, and the heater terminal is securely connected to the pair of connecting terminals even if there is some variation in the installation of the heater terminal and the connecting terminal due to slight installation errors. Ru. In addition, there is no need to connect a cord to the combustion cylinder, which improves handling and operability.Furthermore, when igniting the upper part of the combustion wick in the wick guide cylinder, the ignition heater and the combustion cylinder do not need to be moved, and the upper part of the combustion wick is As a result, the combustion tube is not moved during ignition and the combustion wick is not exposed, so there is no excess air supply, less soot is generated, and no abnormal combustion occurs. In addition, since the combustion cylinder is not moved during ignition, there is no need to adjust the placement of the combustion cylinder, the combustion wick is not caught, and the ignition operating force is small. Since the combustion cylinder is not lifted up, there is no need to set a large gap between it and the reflector, so the main body can be made compact. In addition, since the heater body is detachably attached to the combustion cylinder, the ignition heater can be easily replaced, and since the combustion cylinder is rotatable, the ignition position relative to the ignited part of the combustion wick can be changed. can also be done easily.
