Description
【発明の詳細な説明】 〔発明の利用分野〕 本発明は携帯用集じん丸のこにおける集じん機構に関す
るものである。Description: FIELD OF THE INVENTION The present invention relates to a dust collecting mechanism for a portable dust collecting saw.
従来の集じん丸のこを第３図に示す。丸のこ７により切
断された粉じんの大部分は太矢印のように粉じん排出口

という欠点があった。A conventional dust collecting circular saw is shown in FIG. Most of the dust cut by the circular saw 7 is discharged into the dust collection case 1 from the dust discharge port 5 as indicated by a thick arrow. Here, the dust that has not been discharged to the dust collecting case 1 scatters behind the base 6 as indicated by the thin arrow, so that there is a drawback that the dust collecting performance is deteriorated.
本発明の目的は、上記した従来技術の欠点を解消し、集
じん効率のよい集じん丸のこを提供することである。An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a dust collecting circular saw with high dust collecting efficiency.

る。According to the present invention, the cooling air discharge port of the electric motor is provided on the inner wall portion of the gear cover, and the cooling air is discharged to the air curtain groove provided in communication with the discharge port, whereby dust is discharged to the rear of the base. It is designed to prevent it.
本発明の一実施例を第１図及び第２図に示す。 One embodiment of the present invention is shown in FIGS. 1 and 2.

排出され蓄積される。A circular saw 7 is fixed to an output shaft to which power is transmitted from an electric motor via gears or the like. About the upper half of the circular saw 7,
It is covered with a gear cover 2 and a saw cover 9, and substantially the lower half of the circumference is covered with a safety cover 8 which swings around the output shaft. The dust cut by the circular saw 7 is discharged from the dust discharge port 5 provided in the gear cover 2 to the dust collecting case 1 and accumulated therein.

いることになる。Cooling air from the cooling fan 10 of the electric motor is blown from the cooling air discharge port 3 through the air curtain groove 4 to the side surface and the outer peripheral portion of the circular saw 7. Therefore, the gear cover 2 and the circular saw 7
The gap between them is partitioned by the air curtain by the cooling air.
これにより、粉じん排出口５へ排出しきれずに、ベース

ら後方への粉じんの流出を阻止することができる。According to the present invention, since the cooling air discharge port of the electric motor and the air curtain groove are provided on the inner wall of the gear cover, the gap between the gear cover and the circle is partitioned by the cooling air, and the outflow of dust from the rear side is prevented. Can be stopped.
