Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a liquid fuel combustion device, such as an oil stove, which mixes and burns liquid fuel and combustion air.

(b) Prior Art Conventionally, this type of liquid fuel combustion apparatus has been disclosed in Japanese Utility Model Application Publication No. 56-47371, etc., and this structure has had the following drawbacks.

Adjustment of the oscillator (control box in the publication) must be done with the front section of the main unit removed. If the front section is attached after adjusting the oscillator, the hot air blowing louver etc. fixed to the front section The pressure within the combustion chamber varied, and it was very cumbersome to remove the front section and adjust the oscillator.

In addition, if the electromagnetic pump is used for a long time and its performance (fuel delivery amount) deteriorates, the front part must be removed and the oscillator must be readjusted.
It was extremely troublesome to use.

Furthermore, the above-mentioned troublesomeness occurred when replacing the electromagnetic pump and oscillator.

(c) Purpose The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional technology.

(d) Configuration The present invention includes an electromagnetic pump that supplies liquid fuel to a burner according to the oscillation frequency of an oscillator, and a blower device that supplies combustion air to the burner, and the liquid fuel supplied by the electromagnetic pump and the When combustion air is mixed with combustion air supplied by a blower, the oscillator is attached to one side of the tank guide opposite to the hot air outlet, and the closing plate is placed on the warm air so that the oscillator cannot be seen from the outside of the main body. It is attached to the back side of the air outlet, and the closing plate has a small hole for adjusting the adjustment knob of the oscillator from the outside of the main body, and a stopper such as a rubber stopper that normally closes the small hole is attached to the small hole. It consists of

(E) Embodiment An embodiment of the present invention will be explained based on the drawings. 1st
The figure shows a perspective view of the external appearance of the liquid fuel combustion device according to the present invention, in which 1 is an exterior case with a mounting base 2 fixed at the lower end and a top plate 3 at the upper end, and 4 is an oblong hot air outlet 5 at the bottom. This is the front panel. FIG. 2 shows a partially cutaway front view of the liquid fuel combustion device according to the present invention, in which a blower device 6 is provided in the upper left part of the main body, and a combustor 7 is provided in the lower left part with a partition wall 8 in between. A refueling device 10 is disposed on the right side of the main body with a partition plate 9 in between.

The refueling device 10 has a saucer 11 below, and the saucer 1
1 includes an oil tank 1 that is fitted into a tank guide 12;
3 is placed on the tank guide 12, and an oscillator 15 for adjusting the amount of oil supplied to the combustor 7 by the fuel pump 14 is attached to a position facing the hot air outlet 5 of the tank guide 12.

FIG. 3 is a cross-sectional view of the main part of the oil supply device 10, in which a closing plate 16 is attached to the back surface of the hot air outlet 5 facing the oscillator 15 so that the oscillator 15 cannot be seen from the outside of the main body. A small hole 18 is bored in the closing plate 16 at a position opposite to the adjustment knobs 17, 17. Note that 19 normally closes the small hole 18 and controls the adjustment knobs 17 and 1 of the oscillator 15.
7 is a rubber stopper that is removed from the small hole 18 when adjusting the amount of oil supplied to the oil supply pump 14 by operating it from outside the main body with a screwdriver or the like.

As described above, the liquid fuel combustion device according to the present invention is constructed, and the combustor 7 is supplied with liquid fuel from the fuel supply device 10 and blows combustion air from the blower device 6 to perform a combustion operation.

When changing the amount of oil supplied by the fuel pump 14 to change the amount of combustion in the combustor 7, when adjusting the adjustment knobs 17, 17 of the oscillator 15, the rubber stopper 1
9 and adjust the adjustment knobs 17, 17 through the small hole 18 using a screwdriver or the like.

(F) Effect As described above, in the liquid fuel combustion device according to the present invention, when changing the combustion amount of the combustor 7, the rubber plug 1 of the small hole 18 of the closing plate 16 on the back side of the hot air outlet 5 is used.
By removing the stopper 9 or the like and adjusting the adjustment knobs 17, 17 from the outside of the main body using a screwdriver or the like, the oil supply amount of the oil supply pump 14 can be changed, without having to remove the front panel 4 as in the conventional case. This is extremely significant in terms of end use.
