Description

[Detailed explanation of the idea] The present invention relates to a hot air heating device.

In recent years, there has been a rapid increase in the number of so-called completely enclosed hot air heating systems that take in air from outside and exhaust it to the outside.In these types of hot air heating systems, the exhaust pipe is guided from the back and is exposed to the outside through a wall or window. However, according to the Japanese Industrial Standards (JIS), hot air heating devices must be equipped with a device that can be fixed to the floor or wall.
At the same time, the back plate prevents the exhaust pipe from being exposed and prevents it from coming into contact with curtains, etc.

Moreover, since the radiant heat of the exhaust pipe is trapped between the main unit and the wall or window when the main unit is installed in this condition, openings such as slits are provided in the upper part of the back plate to dissipate the heat. Ta.

However, this heat is dissipated by natural convection, so especially when the exhaust pipe is extended laterally and led outside, the temperature of the exhaust pipe increases the temperature of the wall or window, so walls made of cloth, etc. are used. In some cases, it may become discolored or burnt.

The present invention was developed in view of the above points, and a part of the air from the hot air blower installed inside the device body is guided between the device body and the wall or window, and the heat that remains there is forcibly removed. This was done as if to remove it.

The present invention will be explained below with reference to the drawings.The main body of the hot air heating device 1
A burner 3 and a combustion chamber 4 are arranged in the upper part of the frame 2, and a hot air blower 5 is arranged in the lower part, and a hot air blowing looper 6 is provided in the front of the frame 2, and a blower phase opening lower is provided in the back. be.

Further, a blower cover 8 and a partition plate 9 are provided in the frame 2 so that the blower 5 can blow air around the combustion chamber 4 and toward the open lower part. A part of the exhaust gas is discharged to the rear of the frame 2 near the exhaust pipe 11 through the open lower part.

The exhaust pipe 11 communicates with the combustion chamber 4, and the tip of the exhaust pipe 11 and the intake pipe 10, which communicates with the burner 3, becomes an intake and exhaust pipe 12 integrated outside the frame 2. penetrates the wall 13 and faces the outdoors.

Further, a substantially U-shaped back plate 14 is provided on the back of the frame 2 for fixing the main body 1, and the top plate 15 of the back plate 14 is provided with ventilation slits (16.16). Face plate 1
7 is provided with a fixing screw hole 18.18.

Therefore, the area near the exhaust pipe 11 through which exhaust gas exceeding 100°C passes becomes high temperature due to radiant heat, but part of the air from the blower 5 before heat exchange flows out from the open lower to the vicinity of the exhaust pipe 11. 16.1.
6, the radiant heat from the exhaust pipe 11 is always guided into the room while the main body 1 is in operation, and the indoor temperature can be raised more effectively.

Furthermore, since the exhaust pipe 11 is cooled by the wind from the lower opening, the temperature of the exhaust gas discharged outside through the exhaust pipe 11 can be lowered, heating efficiency can be increased, and damage such as discoloration and scorching of the wall 13 can be prevented. can.

As described above, according to the present invention, an opening is provided at the back of the frame of the main body, and a part of the air from the hot air blower before heat exchange is guided through the front opening to the vicinity of the exhaust pipe at the rear of the frame. , the indoor temperature can be raised more effectively, and the temperature of the exhaust gas discharged outside through the exhaust pipe can be lowered, increasing heating efficiency and preventing discoloration or burnt surfaces on the wall where the main unit is installed. This has effects such as being able to prevent damage.
