DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid fuel combustion device.

[0002]

FIG. 3 is a front view of a conventional oil hot air heater.
FIG. 4 is a side sectional view of a conventional oil warm air heater. In the figure, reference numeral 1 denotes a heater main body, 2 denotes an operation display unit disposed above the heater, 3 denotes a front outer case, and 4 denotes a control board unit for controlling the heater main body 1. Reference numeral 5 denotes a hot air outlet provided at the center of the front of the heater main body 1, and reference numeral 6 denotes a grill provided on the front of the main body 1 so as to cross the hot air outlet 5.

[0003] 7 is a burner, 8 is a combustion tube, 9 is a wind tunnel surrounding the combustion tube 8, 10 is a blower provided on the back of the heater body 1, 11 is a shell case around the heater body 1,
2 is the upper outer case, and 13 is the blower cover.

[0004] In the heater having the above-described configuration, the gasified gas of kerosene ejected from the burner 7 is burned in the combustion tube 8, and the resulting high-temperature gas is made into the appropriate temperature air by the air from the blower 10. The air is discharged from the hot air outlet 5 through the wind tunnel 9 to heat the room.

[0005]

However, in a conventional liquid fuel combustion apparatus having an operation display section at the top, FIG.
As is clear from the above, the sub-heat from the wind tunnel is directly transmitted to the operation display section because the bottom of the operation display section is vacant, especially when dust adheres to the blower cover and the air volume of the blower decreases. The sub-heat from the heater becomes high temperature and acts to deteriorate the electric components of the operation display unit. Further, when water or the like enters from the joint between the operation display unit and the upper shell case, it falls down as it is, enters the burner or the control board unit, and may cause an electric shock, a short circuit, or the like. Numeral 14 indicates a falling water drop.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and aims at protecting the electric parts of the operation display unit provided on the upper part of the main body from heat and preventing accidents due to water leakage from the upper part. It is an object of the present invention to obtain a liquid fuel combustion device that can be prevented.

[0007]

According to the present invention, there is provided a liquid fuel combustion apparatus having an upper shell case, a front shell case, and an operation display section disposed on an upper portion of a main body, and having a control section and a combustion section below it. At the same time, the upper shell case is bent and extended to the front shell case through the lower side of the operation display unit, and the extension of the upper shell case extends from one end of the main body to the other end via the control unit and the combustion unit. The upper shell case and the extension are integrally molded so as to have a groove that extends and tilts at the same time,
The extension is fixed to the front shell case, and the operation unit is shielded from the control unit and the combustion unit.

[0008]

According to the present invention, the extension of the upper shell case shields radiant heat from the wind tunnel without increasing the number of parts or adding work in the assembling process.
Water that has entered from the joint between the upper outer case and the operation display section is drained through the groove, and the strength of the top surface of the apparatus is further increased.

[0009]

FIG. 1 is a front view of an oil hot air heater according to one embodiment of the present invention, and FIG. 2 is a side sectional view of the oil hot air heater according to one embodiment of the present invention. In the figures, FIG. 3, FIG.
The same reference numerals denote the same items, and a description thereof will be omitted. Reference numeral 12a is an outer shell case extension extending from the upper outer shell case 12 to the lower side of the operation display unit 2 to shield the operation display unit 2, and its end is fixed to the front outer shell case 3. . As shown by a broken line in FIG. 1, the outer shell case extension 12a is formed to have a slope from one end of the heater main body 1 to the other end, in this embodiment, from the left end to the right end of the front surface, Further, a groove 12b is provided along this inclination.

[0010] In this oil hot air heater, the secondary heat from the wind tunnel 9 is shielded by the outer shell case extension 12a, so that the influence of the secondary heat on the operation display unit 2 is reduced. Therefore, it is possible to prevent deterioration of the quality of the electric components of the operation display unit 2 and extend the life thereof.

The operation display unit 2 and the upper shell case 12
Even if water or the like enters from the seam, the water flows down the groove 12b of the outer shell case extension 12a without flowing down to the right end of the heater main body 1, and falls from there (FIG. 1).
No. 14 indicates a drop of water in this state), so that there is no influence on the control board unit 4 and the burner 12, and an accident such as electric shock or short circuit can be prevented.

The upper shell case 12, including its extension 12a and groove 12b, is manufactured by integral molding.

[0013]

According to the liquid fuel combustion apparatus of the present invention,
Since the operation display section on the upper part of the main body is shielded by the extension of the upper outer case, the influence of radiant heat on the operation display section can be reduced, and the quality deterioration can be prevented. at the same time,
Since the extension portion functions as an inclined drain groove, even if there is water leakage or the like from a joint between the upper outer case and the operation display portion, it is possible to prevent the leakage from affecting the control board and the burner. Further, since the upper shell case is fixed to the front shell case via the extension, the strength of the top surface of the apparatus can be increased. In the case of the present invention, the member acting as the shielding plate, the drainage groove and the reinforcing material is also used as one extended portion,
In addition, since the extension and the upper shell case are integrally formed, the above-described effects can be achieved without increasing the number of parts or adding work in the assembling process.
