Description

[Detailed description of the invention] This invention has a burner removably mounted inside the wick and on the upper part of the outer cylinder, and a spark plug for discharging is installed at a position corresponding to the exposed part of the wick, and the spark plug is installed at a position corresponding to the exposed part of the wick. The present invention relates to a wick type oil combustor with an upper and lower wick in which the wick is ignited by electric discharge.

As this kind of oil burner, a double-tube oil stove as shown in FIG. 1 is known.

In FIG. 1, 1 is an outer core cylinder 1, 2 is an inner core cylinder, and a core 3 is inserted between the inner and outer cores so as to be vertically slidable.

Reference numeral 4 denotes a burner detachably mounted on the upper end flange of the inner core and outer cylinder, and is separated from the inner flame cylinder 5, the outer flame cylinder 6, and the outer cylinder 7.

8 is a handle of the burner 4. Reference numeral 9 denotes a spark plug for discharging, as shown in FIG. 1, which is installed from outside the flange portion 1a of the outer core cylinder 1 into the space between the inner and outer flame cylinders 5 and 6.

10 is a discharge electrode. Figure 2 is a circuit diagram of the discharge circuit.
11 is a power source such as a battery, 12 is an ignition switch provided on the outside of the stove body, and 13 is a high voltage generator that generates a high voltage of 14 KV, which is discharged from the discharge electrode 10 of the spark plug 9 toward the inner flame cylinder 5. have them do it.

As shown in Fig. 1, when igniting the wick 3 in the normal state where the burner 4 is placed inside the wick and at the upper end of the outer cylinder, after raising the wick 3, press the ignition switch 12 and press the discharge circuit. is turned on, and spark discharge is performed from the discharge electrode 10 toward the grounded inner flame cylinder 5.

This discharge ignites the wick 3, so the ignition switch 12
turn off and stop discharging.

In such a state, the discharge electrode 10 is surrounded by the burner 4, so there is no risk of electric shock to a person.

However, when the burner 4 is removed from the core inner/outer cylinder, such as when replacing the wick 3, or when the burner 4 is lifted from the core inner/outer cylinder, the discharge electrode 10 is exposed, and the inner flame cylinder If the ignition switch 12 is accidentally turned on at this time, a high voltage will be generated at the electrode 10, creating a risk of electric shock.

Therefore, in the present invention, the discharge circuit is connected to the ignition switch 1.
A safety microswitch is provided separately from the switch 2 to turn off the power, in order to prevent electric shock accidents.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Note that the same parts as in FIGS. 1 and 2 are denoted by the same reference numerals.

In Fig. 3, 14 is the main body of a reflective oil stove;
In front of it is a front guard 1 that guards the front of the burner 4.
5 is pivotally supported by a support shaft 16 so as to be openable and closable.

The other end side rod 17 of this guard 15 can be freely engaged and detached from an engaging part 18 attached to the rear reflector 20, and the guard 15 can be rotated by 90' to 120 degrees around the support shaft 16. do.

The upper end of the support shaft 16 is inserted into a hole (not shown) drilled in the upper reflector plate 19 of the stove, and a single-shaped support is screwed to the rear reflector plate 20 as shown in FIG. Board 2
The lower end is inserted into the hole 22 of No. 1, and can be removed from the stove body 14 by lifting the upper end upward, removing the lower end from the hole 22, and then lowering the upper end.

A cross-shaped positioning projection 23 as shown in FIGS. 4 and 5 is attached to the lower end of this support shaft 16.
A first safety microswitch 24 (hereinafter referred to as a safety switch) is fixed at a position on the rear reflector plate 20 corresponding to No. 3.

When the guard 15 is attached to the stove body 14 as shown in FIG. 3, the push button 24a of this safety switch 24 is pressed by the protrusion 23 as shown in FIG. 4.5, and turns on the switch 24. state.

However, if the rod 17 of the guard 15 is even slightly disengaged from the engaging portion 18, the support shaft 16 rotates as shown in FIG. returns and switch 2
4 is in the off state.

FIG. 7 is a sectional view of a main part of the oil stove, and FIG. 8 is a plan view.

In the figure, reference numerals 25, 25 are single-shaped burner angles fixed to both sides of the outer cylinder 7 of the burner 4, and the lower ends are connected through positioning holes 27, 27 drilled in the lower reflector 26. and is suspended below the reflecting plate 26.

28 is a second screw fixed to the lower surface of the lower reflector plate 26.
This is a safety micro switch whose contact piece 28a is the seventh
In the state shown in the figure, the burner angle 25 is pressed against the lower end of the burner angle 25 and turned on.

In order to place the burner 4 in the core and on the outer cylinders 2 and 1, it is necessary to insert it into the positioning holes 27 and 27 of the burner angle 25. It is placed correctly only when the burner angle is 25.
will necessarily press the contact piece 28a of the microswitch 28.

Note that the positioning holes 27, 27 are located at the burner angle 25.
25, and can be rotated left and right by 10 degrees to 300 degrees in order to stabilize combustion when the burner 4 is placed thereon.

Figure 9 is a circuit diagram of the discharge circuit, 11 is a power source such as a battery, 1
2 is an ignition switch provided on the outside of the stove body, 24
The first safety switch 24, 28 is the above-mentioned microswitch, and 13 is a high voltage generator that generates a high voltage of 14KV.

In the above-mentioned kerosene stove, if the burner 4 is normally placed on the core and inner and outer cylinders 2 and 1, and the guard 15 is in the closed state as shown in FIG. 3, both the safety switch 24 and the microswitch 28 are turned on. When the ignition switch 12 is pressed, the discharge circuit is turned on, and discharge is performed from the discharge electrode 10 toward the inner flame cylinder 5.

However, if you open the guard 15, remove the burner 4 from the upper ends of the inner and outer core cylinders, or lift the burner 4,
The safety switch 24 is turned off as described above, or the microswitch 28 is turned off by releasing the pressure on its contact piece 28a, so the discharge circuit is turned off regardless of whether the ignition switch 12 is turned on or off, and the high voltage is discharged from the electrode 10. No voltage is generated.

[Other Examples]

In the above embodiment, the microswitch 28 is turned on and off in response to opening and closing of the guard 15, but it may be turned off when the guard is removed from the main body 14.

As described above, according to the present invention, electric shock accidents caused by spark plugs can be completely prevented.
