内、下方部を多孔質材で閉塞したものである。According to a second aspect, an end surface of the cleaner body having an electric blower and a dust trap inside is provided with an exhaust port, and the end surface of the cleaner has a concave shape. The end surface is spaced apart from the inner peripheral surface of the concave section and the exhaust gas is exhausted. A sound insulating wall is provided facing the mouth, and a sound absorbing material is attached to one surface of the sound insulating wall facing the exhaust port, and the inside of the gap between the end surface forming the exhaust port of the cleaner body and the sound insulating wall is located below. The part is closed with a porous material.

And is discharged rearward from the outer periphery of the sound insulation wall. Further, the closing plate prevents the exhaust gas from flowing out downward, and eliminates dust scattering on the floor surface. Moreover, the exhaust gas flowing rearward from the auxiliary exhaust port surely blocks the downward flow of the exhaust gas. Further, in the second means, the exhaust flow rate downward is significantly reduced due to the ventilation resistance of the porous material.
実施例 以下本発明の実施例を添付図面を参照して説明する。Embodiments Embodiments of the present invention will be described below with reference to the accompanying drawings.

してある。The rear end surface 3 is formed in a concave shape, and the coater portion connected to the inner peripheral surface 5 is set to a smooth curved surface. 6
Is an exhaust filter covered inside the exhaust port 4. The concave portion 7 of the rear end surface 3 has an inner peripheral surface 5 and an exhaust port 4 thereof.
And a sound insulating wall 8 is provided with gaps t and t '. Further, a sound absorbing material 9 is attached to the side of the sound insulation wall 8 facing the exhaust port 4.

る。In the above configuration, the exhaust flow that has passed through the exhaust filter 6 spreads in the outer peripheral direction after hitting the sound absorbing material 9 of the sound insulation wall 8 and is then redirected rearward at the corner portion of the smooth curved surface to form the inner peripheral surface of the concave portion 7. It is discharged to the rear outside through a gap t between the surface 5 and the outer peripheral portion of the sound insulation wall 8. During the flow of the exhaust gas, the noise therein is significantly reduced by the blocking action of the sound insulation wall 8 and the sound absorbing action of the sound absorbing material 9, and the exhaust flow rectifying action of the exhaust passage portion formed by the gaps t ', t. Becomes

である。Next, in FIG. 3, the lower part of the gap t'is closed by the closing plate 10, and in this case, the exhaust flow downward is blocked. The significance of the present embodiment can be found in that dust on the floor surface or the like is not blown away by the exhaust flow, and thus proper cleaning can be performed. Further, in FIG. 3, an auxiliary exhaust port 11 having a small opening area is provided in the lower portion of the rear end face 3 adjacent to the closing plate 10 to create an exhaust flow that travels straight rearward, thereby lowering the exhaust flow to the floor surface. This is to prevent the occurrence more reliably.

In the case of this embodiment, the ventilation resistance of the porous material 12 reduces the exhaust flow velocity downward. And does not affect the dust on the floor.

るものである。As described above, according to the present invention, the end surface of the cleaner body having the exhaust port is formed in a concave shape, and the sound insulation wall is provided at a distance from the inner peripheral surface of the concave portion and facing the exhaust port. A noise absorbing material is attached to the surface of the sound insulating wall that faces the exhaust port, so the noise in the exhaust is reduced by the sound insulating wall's blocking function, the sound absorbing material's sound absorbing function, and the exhaust flow rectifying function. The energy is surely attenuated, so that the noise reduction during the cleaning work can be greatly improved. In addition, because it is designed to regulate downward exhaust,
The dust on the floor and the like is not blown off, and an excellent effect such as hygienic and reliable cleaning can be achieved.
