In addition, the preferred so that communication paths 39 of air-breathing oral area 35 and exhaust oral area 38 arranges with the mode of swept surface almost parallel.Adopt this structure, can make from air-breathing oral area 35 and suck and consistent with the mobile direction vector of the wind that suction chamber 12, flows through the direction vector that flows of the extraneous gas of communication paths 39, the turbulent this situation of suction chamber 12 interior generations can be suppressed at fully, the quietness of suction pieces 1 main body can be further improved.
At the downside of communication paths 39, be provided with the spatial portion 40 as absorption chamber on the top of suction chamber 12, be provided with a plurality of bloops 37 of connection space section 40 and suction chamber 12.In addition, be provided with the sound absorbing member 41 with erasure effect at spatial portion 40 in the mode of stopping up bloop 37.
Wind noise and the noise that suction chamber, produces, the further quietness of reinforced suction part main body that the extraneous gas that thus, can utilize sound absorbing member to be absorbed in to suck from air-breathing oral area 35 produces during by communication paths 39.In addition, by near communication paths 39, with respect to communication paths 39 absorption chamber (spatial portion 40) being set independently, can utilize absorption chamber to be reduced in the wind noise that when the extraneous gas of air-breathing oral area 35 suctions passes through communication paths 39, produces, can improve the quietness of suction pieces 1 main body.
About the as above suction pieces of electric dust collector 100 usefulness of formation, below its action of explanation and effect.
At first, if the user makes main body of dust collector 2 entrys into service for swept surface is cleared away, then produce suction wind by electric blower.If produce suction wind by electric blower, then via flexible pipe 8, extension tube 9, control of dust path 19 and connecting path 17, extraneous gas is flowed into from peristome 12a and the air-breathing oral area 35 of suction chamber 12.In addition, supply with to control circuit 14 and motor 13 through extension tube 9 from the supply capability of main body of dust collector 2.Thus, motor 13 rotations, and by Timing Belt 30 driving rotating brushes 15.
By rotating brush 15 rotations in the suction chamber 12, under by the effect of hairbrush 33 and all brushes 34, the dust of swept surface breaks away from ground.Dust is flowed into the suction wind of suction chamber 12 and is collected, and is collected into the dust collecting part 4 of main body of dust collector 2 through connecting path 17, control of dust path 19, extension tube 9 and flexible pipe 8.In addition, the peristome 12a from suction chamber 12 arrives the suction wind main composition of connecting path 17 through this stream of the downside of suction chamber 12.In addition, reduce sound press by the rotation sound process bloop 37 of hairbrush 33 and week brush 34 generations and by sound absorbing member 41, thereby can carry out quietization.That is, absorption chamber (spatial portion 40) absorbs the rotation sound of rotating brush.
Then, the air-breathing wind that flows into from air-breathing oral area 35 at first makes lid 36 open, and arrives exhaust oral area 38 through communication paths 39, becomes the wind in the upper side flow of suction chamber 12.The air-breathing wind that flows into from air-breathing oral area 35, until before flowing to connecting path 17, the step of process, barrier etc. are less, and, after arriving connecting path 17, there is not unnecessary step etc. yet.Thus, when the suction wind that sucks at the air-breathing wind that flows into from air-breathing oral area 35 and lower surface from suction chamber 12 converges, also can suppress fully the generation of the turbulent flow in the suction chamber 12, in tube connector 18, flow swimmingly.Therefore, can reduce the wind noise of suction pieces 1 inside.
In addition, since at the extraneous gas that sucks from air-breathing oral area 35 until the path before arriving suction chamber 12, namely communication paths 39 in do not have the barrier such as sound absorbing member, therefore can suppress fully the extraneous gas that sucks from air-breathing oral area 35 and disperse, and the extraneous gas that has passed through communication paths 39, produce the situation of turbulent flow because of barriers such as sound absorbing members.
And, owing to separately aspirated by the peristome 12a from air-breathing oral area 35 and suction chamber 12 from the suction wind of suction pieces 1 suction, therefore can reduce the suction wind of suction chamber 12 inside amount, reduce flow velocity, therefore can reduce the sound press of the wind noise that suction pieces 1 produces.
Thus, begin the running of electric dust collector 100 and the air that sucks from suction pieces 1 main body by the user, to disperse to flow in the suction chamber 12 from air-breathing oral area 35 and peristome 12a, therefore the wind noise that produces owing to from suction pieces 1 main body air amount can be reduced, the quietness of suction pieces 1 main body can be improved.
And, owing to can be suppressed at fully the situation that produces turbulent flow in the extraneous gas that has passed through communication paths 39, therefore can suppress fully when the extraneous gas that has passed through communication paths 39 with the air that sucks from peristome 12a during in suction chamber 12 interior collision, in the turbulent situations of suction chamber 12 interior generations.Therefore, the noises such as wind noise of suction chamber 12 interior generations can be reduced in, the quietness of suction pieces 1 main body can be improved.
As mentioned above, in the present embodiment, on the top of suction chamber 12, be provided with independently the spatial portion 40 as absorption chamber that is surrounded by lower member 11 and upper member 10 with respect to communication paths 39.In addition, in this spatial portion 40, dispose sound absorbing member 41.Thus, the sound press of the level of noise that suction pieces 1 produces can be reduced, quietization can be realized.
So, by using the suction pieces 1 in the present embodiment, can provide a kind of higher electric dust collector 100 of noise, quietness that can reduce when clearing away operation.
Utilizability on the industry
As mentioned above, according to the present invention, since can provide a kind of with the quiet electric dust collector that turns to characteristics with suction pieces and have this electric dust collector with the electric dust collector of suction pieces, be useful with the home-use electronic dust catcher of suction pieces and industry with electric dust collector etc. as using electric dust collector therefore.
