ンク、２８は石油燃焼暖房機である。 As shown in FIGS. 1 and 2, the configuration of the ventilation duct includes a top plate 15, a front plate 16, a bottom plate 17, and side plates 18.
A combustion tube 6 is placed over a combustion section 5 installed in a blower duct 19, and a propeller blower 7 is installed upstream of the combustion tube. Then, by blowing air into the air duct with a propeller blower, warm air that has undergone heat exchange in the combustion tube is discharged from the blower outlet 8. Further, the top plate is tilted downward in the downstream direction, and a partition plate 21 is provided at the top of the combustion cylinder to vertically divide the ventilation passage between the top 20 of the combustion cylinder and the top plate, and the partition plate is located at the top of the combustion cylinder. The structure is such that a plurality of cut and raised plates A22 inclined in the downstream direction are provided in the portion. 23 is cut and raised, 24 is knee board A, 25
26 is a heat-resistant sound-absorbing board, 27 is an oil tank, and 28 is an oil-burning heater.

る。 In such a configuration, the sound generated in the combustion section is radiated from the catalyst purification filter of the combustion cylinder toward the partition plate, and the sound generated in the combustion section is emitted from the catalyst purification filter of the combustion tube toward the partition plate, and the sound generated by the combustion section is emitted from the catalyst purification filter of the combustion cylinder toward the partition plate.
is reflected to the upstream side of the ventilation duct. At this time, since the kneeling plate A is also provided with a cut-and-raised plate B29 that slopes downward toward the downstream direction and is provided with a cut-and-raised window, the radiation is easily radiated to the upstream side.
また、切り起こし窓から天板方向へ放射する音

能と低騒音性能を得ることができる効果がある。 Furthermore, the top plate of the air duct and the partition plate are configured to slope downward in the downstream direction, and the cut-out plate provided on the partition plate is configured to slope downward in the downstream direction. The ventilation passage between the top plate of the ventilation duct is widened, and the bending angle between the front plate and the top plate of the ventilation duct is made gentler.
This has the effect of reducing blowing resistance and increasing the amount of air blown. Since the partition plate is provided between the top plate of the ventilation duct and the top of the combustion cylinder, it is closer to the combustion section than the top plate, and the temperature is usually very high. The partition plate may be deformed due to the temperature rise, and desired air blowing performance and noise performance may not be obtained. However, in the configuration of the present invention, since the first knee plate provided on the partition plate is provided with a plurality of cut-out plates tilted downstream and downward, the air is blown by the blower. The temperature of the hot air can be lowered in two places: between the partition plate and the combustion tube, and in the ventilation passage between the blower duct and the partition plate, so the temperature rise of the partition plate can be suppressed from both the front and back sides, and the temperature rise can be suppressed from the top of the air duct. This has the effect of suppressing temperature rises, improving safety and durability, as well as providing high air blowing performance and low noise performance.

る。Effects of the Invention As described above, according to the present invention, the sound generated in the combustion section is reduced to standing waves due to the reflection and transmission effects of the cut-and-raised plate A of the partition plate and the cut-and-raised plate B of the knee plate A. It is possible to suppress generation and reduce noise. The slope of the top plate of the air duct, the slope of the partition plate, and the downward slope of the cut-and-raised plate in the downstream direction create a large air passage, and the gentle bending of the air duct reduces the airflow resistance. This has the effect of reducing the amount of air and increasing the amount of air blown. Also,
The air blown between the cut-and-raised boards of the kneeboard suppresses the temperature rise of the partition board and the top of the ventilation duct, improving safety and durability, as well as providing high ventilation performance and low noise performance. Can be maintained.
