DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot oil heating apparatus in which an apparatus main body is mounted on a table via a mounting leg for level adjustment.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional oil hot air heater, wherein 1 is a table laid on a floor 3 in a room close to a room wall 2 and 4 is a table mounted on the table 1 and mounted indoors. The device body 4 has a horizontally elongated hot air discharge port 5 at the lower front part and an air intake port 6 at the upper rear part,
Inside thereof, a combustion section, a heat exchange section 7 through which the combustion gas of the combustion section flows, and a blower 8 for hot air that blows toward the heat exchange section 7 are housed, and near the lower four corners. Has four mounting legs 9, 9 for horizontal adjustment.
Reference numeral 10 denotes a back gart which is attached to a rear portion of the device main body 4 and covers an upper part of the rear space X between the device main body 4 and the room wall 2 and both left and right sides. Further, a pair of decorative plates 11 for blindfolding four mounting legs 9 for horizontal adjustment mounted on the device main body 4 are mounted on both left and right end portions of the mounting table 1.

[0003]

By the way, in the above-mentioned conventional oil warm air heater, the warm air discharge port 5 is provided at the lower front part of the equipment main body 4, and the air suction port 6 is provided in the equipment main body 4. Because of the arrangement provided on the back, the hot air outlet 5
The warm air discharged from the room flows near the floor 3 in the room and reaches far away, so that there is an advantage that the temperature difference between the lower part and the upper part in the room can be minimized. However, since the air suction port 6 is provided on the back of the device main body 4, the mounting legs 9,
In the lower space Y between the bottom surface of the device main body 4 formed by the device 9 and the table 1, an air flow I flowing from the front side to the rear side of the device main body 4 is generated, and is drawn by the air flow I. Part of the warm air discharged from the warm air discharge port 5 flows downward,
There is a problem that the downwardly flowing hot air directly hits the floor 3 in front of the hot air discharge port 5 and raises the temperature of the floor 3 more than necessary. In particular, when the decorative plates 11 and 11 for blindfolding the mounting legs 9 and 9 are mounted on the mounting table 1, the mounting legs 9 are hidden and the installation state is neat. When the apparatus is operated at the maximum heating output, the temperature of the floor 3 rises to about 70 ° C., which is very dangerous.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a mounting plate for horizontal adjustment mounted on a main body of a device hidden by a decorative plate so that a clean and favorable installation state can be obtained. While preventing abnormal rises in floor temperature and confirming fuel leaks.
Make it easier to wipe off leaking fuel.
The purpose of the present invention is to provide an oil hot air heater that can be used .

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a table laid on a floor, a hot air discharge port provided on the table, having a warm air discharge port at a lower front portion, and an air inlet port at a rear portion. ,
And, a device body having a mounting leg for horizontal adjustment attached to the lower portion, and a pair of decorative plates for covering the mounting legs of the device body are provided at both left and right ends of the table , and the mounting table and the device body are A wind shield is provided between the equipment.
It is located directly below the main unit and located at the back of the table.
Is attached to the table at a predetermined interval from the decorative board.
A configuration that is.

[0006]

[0007]

[0008]

With this configuration, the horizontal adjustment mounting legs attached to the lower part of the device main body can be hidden by the pair of decorative plates provided on the table so that they cannot be seen from the outside. The equipment can be installed in good condition, and a wind shield plate is provided between the table and the equipment body, so that airflow is prevented from being generated in the space below the equipment body and the table. It can be suppressed by the air plate, and the temperature of the floor surface in front of the hot air discharge port can be prevented from rising abnormally.

Further , since the wind shield is located immediately below the main body of the apparatus and at the rear of the mounting table, when oil fuel leaks from the fuel supply part in the main body of the apparatus and drops on the mounting table, the fuel leakage is prevented. The confirmation can be easily performed from the front side of the device main body without being hindered by the wind shield.

[0010] Further , since the wind shield plate is attached to the mounting table at a predetermined distance from the decorative plate, when oil fuel leaks from the fuel supply part in the equipment body and drops on the mounting table, the dropped fuel is removed. Through the space between the wind shield plate and the decorative plate, it can be guided to the outer peripheral portion in the mounting table, and the leakage fuel can be easily removed by wiping or the like.
