Abstract

PURPOSE:To protect an operation display unit provided at an upper part of a body against heat and to prevent an accident due to leakage of water, etc., from the upper part. CONSTITUTION:In a liquid fuel combustion apparatus having an operation display unit 2 at an upper part of a body, the unit 2 is shielded by extending an upper shell case 12 to a lower side of the unit 2, the extended part 12a of the case at the lower side of the unit is inclined at one end of the body to the other, and further a groove 12b is provided along the inclination at the part 12a. Radiation heat from a duct is shielded by the extended part, and deterioration of quality of an electric component of the unit is prevented. Even if water, etc., is introduced from a seam between the case and the unit, it is dropped to the end of the body and does not affect influence to a control board, a burner.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a liquid fuel combustion apparatus.

0002

[Prior Art] Figure 3 is a front view of a conventional oil hot air heater.
FIG. 4 is a side sectional view of a conventional oil hot air heater. In the figure, 1 is a main body of the heater, 2 is an operation display section disposed on the upper part of the heater, 3 is a front outer case, and 4 is a control board section for controlling the main body 1 of the heater. Reference numeral 5 denotes a hot air outlet provided at the center of the front surface of the heater body 1, and 6 a grill provided on the front surface of the main body 1 so as to cross the hot air outlet 5.

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 this heater body 1, 11 is an outer shell case surrounding this heater body 1, 1
2 is the upper outer shell case, and 13 is a blower cover.

[0004] The heater configured as described above burns the vaporized gas of kerosene ejected from the burner 7 in the combustion tube 8, converts the resulting high-temperature gas into appropriately heated air using air from the blower 10, and converts this appropriately heated air into air. The hot air is passed through the wind tunnel 9 and discharged from the outlet 5 to heat the room.

[0005]

[Problems to be Solved by the Invention] However, in the conventional liquid fuel combustion apparatus equipped with an operation display section on the upper part, as shown in FIG.
As is clear from the above, since the bottom of the operation display is empty, side radiation heat from the wind tunnel is directly transmitted to the operation display. The secondary heat from the engine reached a high temperature, which deteriorated the electrical components of the operation display. Furthermore, if water or the like enters the joint between the operation display section and the upper outer case, it will fall downward and enter the burner or control board section, potentially causing electric shocks, short circuits, etc. 14 indicates falling water droplets.

[0006] This invention was made to solve the above problems, and is intended to protect the electrical components of the operation display section provided at the top of the main body from heat, and to prevent accidents caused by water leakage from the top. The purpose is to obtain a liquid fuel combustion device that prevents

[0007]

[Means for Solving the Problems] The present invention provides a liquid fuel combustion device having an operation display section on the upper part of the main body, in which the upper outer shell case of the main body is extended below the operation display section to display the operation display section. The outer shell case extension below the operation display is inclined from one end of the main body to the other end, and the outer shell case extension is provided with a groove along the inclination.

[0008]

[Operation] In the present invention, the extension of the upper shell case extending below the operation display section shields the side radiation heat from the wind tunnel. Furthermore, if water or the like enters the joint between the upper outer shell case and the operation display section, the water will flow down to the end of the main body through the groove of this extension.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of an oil hot air heater showing an embodiment of the present invention, and FIG. 2 is a side sectional view of the oil hot air heater showing an embodiment of the invention. In the figure, Figure 3, Figure 4
The same reference numerals indicate the same parts, and the explanation will be omitted. In addition, 12a is an outer shell case extension part that extends from the upper outer shell case 12 to the lower side of the operation display section 2 to shield the operation display section 2, and its terminal end is fixed to the front outer shell case 3. . As shown by the broken line in FIG. 1, this outer shell case extension part 12a is formed with an inclination that descends from one end side of the heater main body 1 to the other end side, in this embodiment, from the left end to the right end in the front, Furthermore, a groove 12b is provided along this slope.

In this oil hot air heater, the side radiation heat from the wind tunnel 9 is shielded by the outer shell case extension 12a, so that the influence of the side radiation heat on the operation display section 2 is reduced. Therefore, it is possible to prevent quality deterioration of the electrical components of the operation display section 2 and extend their lifespan.

[0011] Furthermore, the operation display section 2 and the upper outer shell case 12
Even if water enters from the joint, the water will not fall down, but will flow through the groove 12b of the outer shell case extension 12a to the right end of the heater body 1, and fall from there (Fig. 1
14 indicates falling water droplets in this state), there is no influence on the control board section 4 or the burner 12, and accidents such as electric shock and short circuit can be prevented.

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

[0013]

[Effects of the Invention] As explained above, according to the liquid fuel combustion device of the present invention, the upper outer shell case is extended to shield the operation display section disposed at the top, so that the operation display section can be easily accessed. By reducing the influence of side radiation heat, it is possible to prevent quality deterioration. In addition, this extension is sloped and has a groove, and the bottom of the slope is close to one end of the device, so even if water leaks from the joint between the upper shell case and the operation display, water will flow through this extension. Since it is transmitted and falls to the edge, there is no effect on the control board or burner. Additionally, it has the effect of increasing the strength of the top of the device.
