Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a burner device used mainly in a humid place such as a burner for a bathtub.

(Prior Art) The applicant of the present application formed an air chamber on the outer periphery of a combustion cylinder having a large number of secondary air holes on the circumference, and installed an air nozzle and a fuel nozzle in an opening provided at the rear of the combustion cylinder. We have proposed a system in which fuel is supplied in the form of mist into the combustion cylinder by the air discharged from the air nozzle.

(Problems to be Solved by the Invention) In this device, it is desired that all controls be performed using air from the air supply source.

In other words, when controlling equipment powered by an external power source, it is necessary to control the air system and the electrical system separately, and the commercial power source must be installed in a humid place such as a bathroom. is difficult to bring in.

Therefore, as mentioned above, it is desirable that all controls be controlled by air from an air supply source.

(Means for Solving the Problems) The purpose of the present invention is to obtain a device that satisfies such demands, and the purpose of the present invention is to provide an air chamber on the outer periphery of a combustion tube that has a large number of secondary air holes on its periphery. At the same time, an air nozzle and a fuel nozzle face an opening provided at the rear of the combustion cylinder, and the fuel is supplied in the form of a mist into the combustion cylinder by the air discharged from the air nozzle, A generator is provided that is driven by air pressure from an air supply source that supplies air to the air nozzle, and the control mechanism is controlled by the electromotive force of the generator.

(Function) The combustion in the present invention first drives an air pump, which is an air supply source, and blows out air from an air nozzle. In this case, a mist of fuel is supplied into the combustion cylinder from the fuel nozzle in an amount corresponding to the amount of air supplied. Therefore, when igniting it using an appropriate means, first the so-called raw combustion in which the atomized fuel burns as it is in the combustion chamber begins, and when the combustion chamber is heated by this combustion, the atomized fuel This is so-called premix combustion in which air is premixed and gasified, and combustion occurs at the opening of the combustion tube while receiving secondary air from the secondary air hole.

So far, there is no particular difference from what was proposed earlier.

The present invention provides a generator driven by the airflow from the air supply, and the generator is driven by the airflow from the air supply. In this case, by providing only the air supply source separately, the control equipment installed in the burner device can be driven by the electric power obtained by the generator, and the burner device itself can be There is no need to bring in a power source, eliminating the danger associated with electrical leakage.

(Example) An example of implementing the present invention will be described with reference to the attached drawings.

In the drawing, 1 is a combustion tube with a large number of secondary air holes 1a on its circumferential surface, 2 is an air chamber on the outer periphery of the combustion tube 1, 3,
Reference numeral 4 indicates an air nozzle and a fuel nozzle that face an opening 5 provided at the bottom of the combustion tube 1. The air nozzle 3 is connected to an air pump 6 serving as an air supply source, and when air is ejected from the air nozzle 3. , fuel is supplied into the combustion cylinder 1 in the form of mist from the fuel nozzle 4.
To explain this in more detail, the air chamber 2 is
It is formed between the combustion cylinder 1 and an outer cylinder 7 surrounding it, and the outer cylinder 7 is extended rearward to a large extent so that air pressure from the air nozzle 3, the fuel nozzle 4, and the air pump 6 is applied to the outer cylinder 7. Motor 8 driven by
A generator 9 driven by the generator 9 and a fan 11 facing an opening 10 provided at the rear end of the outer cylinder 7
and has been established.

The one shown has an opening 4 on the bottom of the combustion cylinder 1.
However, it may be located on the side as long as it is at the rear of the combustion tube 1. Furthermore, the air nozzle 3 of the opening may be faced with a gap from the openings 4 and 5 as shown in the figure. The air nozzle 3 may be attached to the periphery of the opening 5 or by being tied to the periphery of the opening 5.

In the drawings, reference numeral 12 indicates a spark plug provided in the combustion tube 1 through the opening 5, and reference numeral 13 indicates an electromagnetic safety valve interposed in a passage 14 that communicates the air nozzle 3 with the air pump 6. The valve 13 is configured to be pressed open by the operating gap 13a, and is held open by the electromotive force of the thermocouple 15 facing the front of the combustion cylinder 1.

Incidentally, a pressure receiving plate 13b was provided on the operating rod 13a.

When doing so, if for some reason the air pump 6
The amount of air supplied from the fuel nozzle 4 increases abnormally, and the amount of fuel supplied from the fuel nozzle 4 also increases accordingly, completely preventing abnormal combustion from occurring within the combustion tube 1.

Drawing 16 shows a microswitch that closes when the operating rod 13a is pressed for the first time and opens when it is pressed again. The state can be changed.

Furthermore, when this burner device is used as a burner device for a bathtub, only the air pump 6 can be installed outside the bathroom, and with this, it is not possible to bring a commercial 100V AC power source into the bathroom. This is extremely advantageous from the standpoint of preventing electric shock accidents.

(Effect of the invention) As described above, according to the invention, a generator is provided that is driven by air pressure from an air supply source that supplies air to the air nozzle, and the burner device is powered by the electromotive force of the generator. Since the operating circuit is controlled, there is no need to bring in a 100V AC commercial power source to the burner body, which has the advantage of preventing electric shock accidents.
