Description

[Detailed Description of the Invention] The present invention relates to an oil hot air heater in which combustion is performed by a bottomed cylindrical vaporizing burner.

FIG. 1 shows a conventional oil hot air heater of this kind, with reference numeral 1 indicating a base, 2 indicating a main body case placed on the base 1, and 3 attaching the unit to the lower part of the main body case 2 via a mounting base 4. Bottomed cylindrical vaporizing burner, 5
is a flame hole formed in the head of the burner 3, 6 is a combustion duct formed above the burner 3, 7 is a convection blower installed on the back of the main body case 2 so as to face into the combustion duct 6, Reference numeral 8 denotes a hot air outlet formed at the upper front surface of the main body case 2.

In this type, when oil and combustion air are supplied to the burner 3, the oil is vaporized within the burner 3, mixed with the combustion air, reaches the flame hole 5, and is burned there.

The hot air generated by this combustion mixes in the combustion duct 6 formed above the burner 3 with the indoor air sent from the convection blower 7 attached to the back of the main body case 2, and becomes warm air. Warm air is blown out from a hot air outlet 8 opened at the upper front of the main body case 2 to perform hot air heating.

By the way, in such conventional products, the bottomed cylindrical burner 3 is installed vertically, that is, vertically, with respect to the base 1 on which the main body case 2 is placed, so that the flame hole 5 that performs combustion is located in the burner 3. The height of the foot is equal to that of the vaporization chamber, and since the combustion duct 6 is located above the flame hole portion 5, the air inside the combustion duct 6 is When air is supplied and mixed with the combustion heat from the burner 3 to produce hot air for heating, the hot air outlet 8 is located at the upper front of the main body case 2, which is disadvantageous in terms of heating from the feet as a heater. There was a certain drawback.

Therefore, in order to improve the above drawback, a bottomed cylindrical burner was installed horizontally at the bottom of the main case so that it was parallel to the base on which the main case was placed, and a combustion duct was installed in front of the burner.
Furthermore, a convection blower is installed at the bottom of the back of the main case, and hot air is discharged from the bottom of the front of the main case along the floor.

However, in such a structure, the vaporization chamber of the burner is generally formed by die-casting, and the inner wall surface of the vaporization chamber is oriented from the bottom toward the opening to improve punching during die-casting. Because the oil is spread out in a tapered shape, if trouble occurs during ignition and oil to be vaporized is supplied to the vaporization chamber when it does not have the heat necessary to vaporize the oil, it will not be able to vaporize into the vaporization chamber. The disadvantage was that oil could not be stored and the oil would flow out of the burner along the taper.

The present invention was made to further improve these shortcomings, and the burner is installed horizontally in the lower part of the main body case, and a groove is formed along the circumferential direction on the inner wall surface of the head side of the vaporizing chamber of the burner. It has been established,
This allows hot air to be released from the lower front of the main body case along the floor surface, and also prevents unvaporized oil from flowing out of the burner even if it accumulates in the vaporization chamber during ignition. This was done so that there would be no

An embodiment of the present invention will be described below with reference to FIGS. 2, 3, and 4 of the drawings.

In the figure, 1 is a base, and 2 is a main body case, which has a hot air outlet 8 at the lower front.

6 is a combustion duct, which is located at the base 1 within the main body case 2.
The front and back surfaces facing the hot air outlet 8 are open.

Reference numeral 3 designates a cylindrical vaporizing burner with a bottom, which includes a die-cast vaporizing chamber 3a, a flame hole portion 5 formed at the head of the vaporizing chamber 3a, and a peripheral wall on the inner wall surface of the vaporizing chamber 3a on the head side. It consists of grooves 3b of appropriate depth provided along the direction, and the flame hole portion 5 is connected to the combustion duct 6.
It's coming inside.

Reference numeral 7 denotes a convection blower, which is attached to the lower back of the main body case 2 so as to face the inside of the combustion duct 6.

The present invention has the above-mentioned configuration, and burner 3
When oil and combustion air are supplied into the burner 3, the oil is vaporized in the burner 3, mixed with the combustion air, and ignited and burned in the flame hole 5.

At this time, if ignition trouble etc. occurs and the vaporization chamber 3a
Even if the oil supplied into the chamber is not completely vaporized, the oil is collected in a groove 3b provided on the head side of the vaporization chamber 3a and will not flow out of the burner 3.

Next, the hot air generated by the combustion mixes in the combustion duct 6 with the indoor air sent from the convection blower 7 attached to the back of the main body case 2, and becomes warm air at the hot air outlet 8 at the lower front of the main body case. It is emitted along the floor surface.

As described above, in this invention, a bottomed cylindrical vaporizing burner is installed horizontally at the lower front of the main body case, and a groove is provided along the circumferential direction on the inner wall surface on the head side of the vaporizing chamber of the burner. Therefore, warm air can be emitted from the lower front of the main body case along the floor surface, making it possible to collect heat from the feet.By setting the depth of the groove appropriately, problems such as ignition can be avoided. Therefore, even if oil that has not been completely vaporized accumulates in the vaporization chamber, it will not flow out of the burner, and there is an advantage that a heater that is excellent in terms of safety can be provided.
