Further, in claim 3, a portion of the mounting table located below the exhaust elbow is covered with a mounting table heat shield plate.

According to claim 1 of the present invention, since the ventilation part having a plurality of vertically long circular holes is provided in the upper part of the reflector located in front of the exhaust elbow, high-temperature air near the exhaust elbow is discharged from the ventilation part. High temperature air does not flow to the front of the appliance and remain near the exhaust elbow, and the temperature of the air near the exhaust elbow can be lowered.
In addition, since a plurality of ventilation portions are formed by vertically long circular holes, it is possible to prevent the appearance of the exhaust elbow from becoming unsightly because it is difficult to see.

In addition, according to claim 2, since the ventilation part having a plurality of vertically long circular holes is provided at the height position of the connection point between the exhaust elbow and the radiator in the reflector, the air flows from the radiator to the exhaust elbow. The air passes through the connection point between the exhaust elbow and the radiator, which is first heated by the combustion gas and reaches the highest temperature, and flows to the ventilation part, so that the temperature of the air in the vicinity of the exhaust elbow can be efficiently lowered.

Further, according to claim 3, since the portion of the stand located below the exhaust elbow is covered with the stand heat shield plate, air does not flow to the floor through the holes formed in the stand, and the temperature of the floor rises. In addition, since the air does not flow from the hole of the mounting table located below the exhaust elbow, more air can flow from the ventilation part of the reflector.

Reference numeral 14 denotes a horizontal reflector provided integrally with the reflector 11, which divides the interior of the instrument body 1 into upper and lower parts. .

A radiator 16 is provided above the outer cylinder 10. The outer cylinder 10 is connected to the outer cylinder 10 by a connection cylinder 16a provided at the center of the lower part of the radiator 16. circulates and exchanges heat with the indoor air, and warm air is blown into the room from the outlet 4 formed on the upper part of the front plate 5 installed on the front of the appliance body 1, so that hot air heating is performed together with radiant heating. is performed.
Here, the ventilation part 12 is positioned at a height corresponding to the connecting tube 16a of the reflector 11. As shown in FIG.

A substantially L-shaped exhaust elbow 17 is arranged between the reflecting plate 11 and the back plate 18 of the instrument body 1, and is located on the left side of the outer cylinder 10 when the instrument body 1 is viewed from the front. It is connected to a radiator 16, and the other end is connected to an exhaust pipe of an air supply/exhaust pipe (not shown) provided on the back of the fixture body 1, and exhaust gas heat-exchanged with indoor air in the radiator 16 is released outdoors. It is something to do.

A hot air fan 19 is installed on the back plate 18 of the appliance body 1 and covered with a fan guard 20. The warm air is blown into the room from the outlet 4. - 特許庁
Since the exhaust elbow 17 is located on the left side of the outer cylinder 10 when viewed from the front of the appliance main body 1, if the hot air fan 19 is arranged so as not to increase the size of the appliance main body 1, the outer cylinder 10 can be displaced as shown in FIG. The center of the hot air fan 19 is shifted by A in the direction away from the exhaust elbow 17 with respect to the center.

Reference numeral 21 denotes a stand on which the instrument main body 1 is placed, and has a plurality of cutout holes 22 for providing cutouts for fixing parts. It is closed with a heat shield plate 23 .

Next, the operation of this embodiment will be described.
??When the user presses the operation switch of the operation unit 2 while the heater is stopped, the ignition heater is energized, the combustion fan is driven at a low speed, and the temperature of the pot burner 7 is gradually increased. . Next, when a predetermined time elapses after the ignition heater is energized and the temperature of the pot burner 7 reaches or exceeds a predetermined temperature, the electromagnetic pump 8 is started to be driven and the rotational speed of the combustion fan is slightly increased. The fuel oil sent from the electromagnetic pump 8 is vaporized and ignited by the ignition heater.

After that, the amount of oil fed by the electromagnetic pump 8 and the rotation speed of the combustion fan are increased step by step, and in the process, when the temperature of the pot burner 7 rises, combustion can be continued without energizing the ignition heater. , the ignition heater is turned off. When the ignition operation is finished, main combustion is performed in which the amount of oil supplied by the electromagnetic pump 8 is automatically controlled according to conditions such as the current room temperature so that the room temperature designated by the user on the operation unit 2 is achieved. transition to

The combustion gas rises from the pot burner 7, passes through the outer cylinder 10, and flows to the radiator 16. At this time, the red-hot cylinder 9 in the outer cylinder 10 is heated by the combustion gas and emits radiant heat. is.
The combustion gas that has flowed to the radiator 16 passes through the exhaust elbow 17 and is discharged to the outside from the exhaust pipe of the air supply/exhaust pipe.

At this time, the radiator 16 and the exhaust elbow 17 become hot due to the high-temperature exhaust gas. heat is exchanged by flowing, and is blown into the room as warm air from the outlet 4 on the front upper part of the appliance main body 1. - 特許庁

Here, since the center of the hot air fan 19 is shifted away from the exhaust elbow 17 with respect to the center of the outer cylinder 10, the exhaust elbow 17 side, that is, the left side of the outer cylinder 10 when viewed from the front of the instrument body 1 is the outer cylinder. 10, the amount of air blown is smaller than that on the right side of 10, so the temperature of the air in the vicinity of the exhaust elbow 17 rises. However, in this embodiment, since the ventilation part 12 is formed in the upper part of the reflector 11 and in front of the exhaust elbow 17, the air around the exhaust elbow 17 smoothly flows to the front of the instrument body 1. It is possible to lower the temperature of the air in the vicinity of the exhaust elbow 17 by flowing.
Further, since the ventilation part 12 is provided with a plurality of circular holes 13 arranged in a zigzag pattern, it is difficult to see the exhaust elbows 17 through the holes, thereby preventing an unsightly appearance.

In addition, since the ventilation part 12 is provided by forming a plurality of vertically long circular holes 13 at the height position of the joint between the exhaust elbow 17 and the radiator 16, the combustion gas flowing from the radiator 16 to the exhaust elbow 17 is prevented. The air passes through the joint between the exhaust elbow 17 and the radiator 16, which is heated first and reaches the highest temperature, and flows into the ventilation section 12, so that the temperature of the air in the vicinity of the exhaust elbow 17 can be efficiently lowered. .

In addition, since the ventilation part 12 is provided at the height position of the connecting tube 16a that connects the outer tube 10 and the radiator 16, the reflection of red heat from the red-hot tube 9 in the outer tube 10 is not reduced, and the feeling of heating is provided. It is indestructible.

In addition, since the cutout hole 22 of the mounting table 21 on the side where the exhaust elbow 17 is located is blocked by the mounting table heat shield plate 23, the air with a high temperature in the vicinity of the exhaust elbow 17 flows from the cutout hole 22 of the mounting table 21 to the floor. It does not flow on the surface and can prevent the temperature of the floor surface from rising.

Furthermore, since the air with a high temperature near the exhaust elbow 17 does not flow to the floor through the cutout hole 22 of the stand 21, the air with a high temperature near the exhaust elbow 17 is more likely to flow from the ventilation section 12. This allows the air to flow and more efficiently lower the temperature of the air in the vicinity of the exhaust elbow 17 .
