いる。This soundproofing material 12 rectifies the wind flowing out from the exhaust port 11 to reduce the sound of the wind, and also acts as a sound absorber to reduce noise without reducing the suction performance of the vacuum cleaner. As shown in Figure 2, its structure is as follows: the upper part 13 is a well-ventilated part made of flame-retardant open foam, such as polyurethane foam;
In order to reduce noise, the bracket is made of an adhesive tape 14 made of impermeable polypropylene wrapped around the outside of the polyurethane foam, and the well-ventilated portion 13 side is placed on the side of the fan case 9 of the electric blower 2. It is attached to the circumferential surface of 1o. As shown in FIG. 3, this soundproofing material 12 is made by overlapping a flame-retardant adhesive tape 14 on the back side of a band-shaped soundproofing material 12' made of flame-retardant polyurethane foam or the like. At this time, the width of the adhesive tape 14 is smaller than the width of the soundproof material 12' and forms a well-ventilated area a. Furthermore, one end of the adhesive tape 14 in the longitudinal direction is the same as the soundproofing material 12' and is aligned with the butt part (2), and the other end is formed long enough to protrude beyond the soundproofing material 12'. There is.
