On the other hand, be respectively equipped with rotation the 1st rotating vane 63 and the 2nd rotating vane 64 freely at the 1st cleaning chamber 18 and the 2nd cleaning chamber 19 as rotary cleaning body.The 2nd rotating vane has the plug 66 that aluminium alloy for example etc. is made, and is provided with the helical form slot part 65 that is axially turning clockwise at the outer peripheral face of this plug 66.In the slot part 65 of this plug 66, a plurality of (for example 4) as pliability (such as soft PVC system) cleaning body scan out device, be blade part 67 engages on shape ground in the shape of a spiral with the state that stretches out the wall-forming shape at outer peripheral face.Length direction one lateral edges of the elongated flat board 68 of this blade part 67 forms the heavy wall base portion 69 that engages with the slot part 65 of plug 66.
63 of the 1st rotating vanes as shown in Figure 10 and Figure 11, on its outer peripheral face in the shape of a spiral shape ground respectively be arranged alternately a plurality of (for example 2) as the device of washing the floor of the cleaning body of flexual a, villous 70, be fabric blade part 71, and as flexual, cross section for the clearing apparatus of the cleaning body of Y font roughly, be twayblade portion 72.Fabric blade part 71 is for example used the polyester manufacturing, forms the soft PVC system base portion 69 of heavy wall at a lateral edges of elongated plate-like nylon loop 73 length directions of a villous 70.Twayblade portion 72 be board 68 from blade part 67 with its branch, the cross section is roughly Y font.The length dimension that the length dimension that fabric blade part 71 stretches out from plug 66 stretches out from plug 66 greater than twayblade portion 72.Therefore, when cleaning floor, have only fabric blade part 71 to contact, have the effect of washing the floor with the floor.
Again, the end at the 1st rotating vane 63 and the 2nd rotating vane 64 has belt pulley 75 to be located at integratedly on the plug 66 respectively.And each belt pulley 75,75 of the 1st rotating vane 63 and the 2nd rotating vane is positioned at the 2nd Transmission Room 25, the axial region 76,76 that rotation is located at axial two ends freely respectively be located at housing 15 on bearing 77,77 cooperate, be subjected to rotating support freely.
The outside dimension of the 1st rotating vane 63 is less than the 2nd rotating vane 64, the lower end of the two respectively from cleaning body chamber 18 the 1st and the opening of cleaning body chamber the 2nd 19 downsides slightly stretch out downwards.And the 1st rotating vane 63 and the 2nd rotating vane 64 have only the leading section of fabric blade part 71 to stretch out downwards than the ground plane that constitutes by driven front- wheel 60,60 and driven trailing wheel 58,58.
On the other hand, in the 1st Transmission Room 22, be provided with transmission device, promptly drive conversion equipment 79.This drives conversion equipment 79 as Fig. 1, Fig. 4, shown in Figure 6, be the casing 80 that is arranged on the 1st Transmission Room 22 end side in rotation freely axle supporting its axially be under the 1st roughly shaft-like rotating shaft 81 of direction.In the lower end of the 1st rotating shaft 81, the 1st belt pulley 83 is set in the face of the 1st Transmission Room 22, setting up the 1st endless-belt 82a at 56 of the air turbine side belt pulleys of the 1st belt pulley 83 and air turbine 37 as transmission device.Be provided with the 1st bevel gear 84a in the upper end of the 1st rotating shaft 81.
In casing 80, be provided with along the growing crosswise direction of housing 15 and descend parallel, rotation the 2nd roughly shaft-like rotating shaft 85 and the 3rd rotating shaft 86 freely haply.One end of the 2nd rotating shaft 85 is provided with the 1st bevel gear 84b with the 1st bevel gear 84a of the 1st rotating shaft 81 engagement.The other end of the 2nd rotating shaft 85 is provided with the 2nd belt pulley 87 in the face of the 2nd Transmission Room 25.The position of being partial to an end at the ratio pars intermedia of the 2nd rotating shaft 85 is provided with the 1st gear 88a.Be provided with the 2nd gear 88b with the 1st gear 88a engagement of the 2nd rotating shaft 85 at an end of the 3rd rotating shaft 86.At the other end of the 3rd rotating shaft 86, be provided with the 3rd belt pulley 89 in the face of the 2nd Transmission Room 25.On the 2nd belt pulley 87 of the 2nd rotating shaft 85, and tilt setting up the 2nd endless-belt 82b between the belt pulley 75 of the 1st rotating vane 63 as transmission device.On the 3rd belt pulley 89 of the 3rd rotating shaft 86, and setting up to approximate horizontal the 3rd endless-belt 82c between the belt pulley 75 of the 2nd rotating vane 64 as transmission device.
And for example shown in Figure 6, the 2nd rotating vane 64 1 sides more are partial to than the centre position of 64 of the 1st rotating vane 63 and the 2nd rotating vanes in the center of the 2nd rotating shaft 85, that is, above the 2nd rotating shaft 85 and with the 2nd rotating shaft 85 between the inclination distance of setting up between the 1st rotating vane 63 of endless-belt longer.The 3rd rotating shaft 86 relatively and 86 approximate horizontal of the 3rd rotating shaft set up endless-belt the 2nd rotating vane 64 be in the position of general horizontal direction, the distance that this rotating shaft 86 and the 2nd rotating vane are 64 is shorter.
Because the rotation of air turbine 37 makes 81 rotations of the 1st rotating shaft through the 1st endless-belt 82a, this rotation makes 85 rotations of the 2nd rotating shaft through the 1st bevel gear 84a and the 2nd bevel gear 84b.The rotation of the 2nd rotating shaft 85 makes the 3rd rotating shaft 86 relative the 2nd rotating shafts 85 do reverse rotation by intermeshing the 1st gear 88a and the 2nd gear 88b.In addition, through the 2nd endless-belt 82b, make the direction of advance of the 1st rotating vane 63 relative suction inlet bodies 11 do forward rotation.The direction of advance of 64 relative suction inlet bodies 11 of the 2nd rotating vane is done reverse rotation, that is, the two is rotation to the inside mutually.The 1st rotating vane 63 is towards fine hair 70 1 sideway swivels of fabric blade part 71.
The below action of the above-mentioned example of explanation.
When cleaning, suction inlet body 11 is linked to each other with not shown electric dust collector body by prolonging pipe and flexible pipe.Then the limit hand hose line by prolonging the end of pipe one side, the limit promotes, and makes suction inlet body 11 edge joints touch swept surface, is that the limit, ground moves forward and backward.
Because the inhalation power effect of electric dust collector body, in air-breathing, also suck from the 1st suction inlet 20 and the 2nd suction inlet 23 from air entry 44.At this moment, suction inlet body 11 is placed on the ground, and the 1st suction inlet 20 is between the 1st rotating vane 63 and the 2nd rotating vane 64.Therefore, by the 1st rotating vane 63 and the 2nd rotating vane 64 and ground face closure, the negative pressure of section port body 11 downsides increases.And apart near the 2nd suction inlet 23 of communicating pipes 32 to the 1 suction inlet 20 at cleaning body chamber the 2nd 19 inner openings, so the 2nd rotating vane 64 places' wind path resistances increase.And its aperture area is less than the aperture area of the 1st suction inlet 20.Therefore from the inhalation power of the 1st suction inlet 20 with identical from the inhalation power of the 2nd suction inlet 23.Thereby, be owing to the increase in the face of the suction inlet body 11 downside negative pressure on ground increases the inspiratory capacity ratio from air entry from the soakage of the 1st suction inlet 20 of same degree and the 2nd suction inlet 23 and from the ratio between the soakage of air entry 44.
When ground when more villose carpet etc. is arranged, in the face of the 1st suction inlet 20 on ground by inaccessible.Thereby, the negative pressure of suction inlet body 11 downsides when being the floor than ground, the negative pressure of suction inlet body 11 downsides when ground is carpet is bigger, at this moment, from the soakage increase of air entry 44.
Be vortex shape ground from rectification limit, air entry 44 inhaled air limit by the diminishing horn-like air-breathing supply wind path 43a of sectional area and arrive turbine room 38.This Vorticose suction air-flow makes the proportional speed rotation of air turbine 37 usefulness and inspiratory capacity.This rotary driving force passes to through the 1st endless-belt 82a and drives conversion equipment 79.To be converted to the horizontal direction to the rotation driving that is axle with upper and lower by this driving conversion equipment 79 is 2 rotary driving forces of axle.And then, make the 1st rotating vane 63 and the 2nd rotating vane 64 usefulness and the mutual reverse rotation of the proportional speed of inspiratory capacity through the 2nd endless-belt 82b and the 2nd endless-belt 82c.Rotation by the 1st rotating vane 63 and the 2nd rotating vane 64 scans out dust 90 from ground.The dust that is positioned at cleaning body chamber 18 the 1st 90 that this scans out is inhaled into from the 1st suction inlet 20 through communication air duct 28.The dust 90 that is positioned at cleaning body chamber 19 the 2nd then directly sucks from the 2nd suction inlet 23.In addition, flow into the suction air-flow process intercommunicating pore 45 of belt pulley chamber 38 from 24 inflow communicating pipes 32 of the 2nd suction chamber.
The 1st suction inlet 20 is positioned at the hand of spiral one side of the 1st rotating vane 63.Therefore as shown in figure 12, the direction that sucks of dust 90 power that is inhaled in the cleaning body chamber 18 the 1st and the hand of spiral under the rotation status, the direction that promptly guided by fabric blade part 71 and twayblade portion 72 are same direction.Thereby the dust 90 that scans out from ground is because the effect of attraction and fabric blade part 71 and twayblade portion 72 successfully is inhaled into the 1st suction inlet 20 through ventilation road 28.In addition, the 2nd suction inlet 23 is at the substantial middle opening of the 2nd cleaning chamber 19, and the 2nd rotating vane 64 is done the reverse rotation opposite with the hand of spiral of the 1st rotating vane 63.Therefore, the direction of the direction of inhalation power suction and blade part 67 guiding each other in the other direction.Thereby the part dust 90 that sucks from the 2nd suction inlet 23 does not move to the direction of leaving the 2nd suction inlet 23 at blade part 67.So, through being positioned at the end that is directed side, being located at, making the connection recess 27 that the 2nd cleaning body 19 is communicated with cleaning body chamber 18 the 1st and be drawn towards the 1st cleaning chamber 18, and pass through communication air duct 28 and be inhaled into the 1st suction inlet 20 with the 1st suction inlet 20 opposite sides.
When ground was floor etc., the fabric blade part 71 that only is positioned at the 1st rotating vane 63 of moving direction front side contacted with the floor, can scan out the dust 90 till the wall limit on the floor, simultaneously can the Floor wiper till the wall limit is clean.
The aperture area of air entry 44 is provided with the air turbine 37 that becomes the wind path resistance less than the 1st suction inlet 20 and the 2nd suction inlet 23 in air-breathing wind path 43.Therefore, from the inhalation power reduction of the 1st suction inlet 20 and the 2nd suction inlet 23, almost can not be but do not reach from the degree of the 1st suction inlet 20 and 23 suctions of the 2nd suction inlet.And, because the rotation of the 1st rotating vane 63 and the 2nd rotating vane 64 drives, dust 90 is scanned out, so, can cause dust fully not suck because inhalation power reduces hardly easily with its suction.
When placing flexible pipe on the ground for mobile furniture, the downside of suction inlet body 11 breaks away from ground, suck larger object and the inaccessible occasion of quilt at the 1st suction inlet 20 and the 2nd suction inlet 23, or the 1st rotating vane 63 and the 2nd rotating vane 64 when being twined by the end of a thread or hair etc., they must be taken off.For this reason, when suction inlet body 11 is upwards carried from ground, the negative pressure of suction inlet body 11 downsides reduces, and increases from the soakage of the 1st suction inlet 20 and the 2nd suction inlet 23 and the inspiratory capacity ratio that becomes from the 1st suction inlet 20 and the 2nd suction inlet 23 from the ratio between the soakage of air entry 44.And in the downstream from the turbine room 38 of air-breathing wind path 43 to the air turbine 37 of communicating pipe 32, the 1st suction inlet 20 is open communication through sucking wind paths 34, and the 2nd suction inlet 23 is direct openings simultaneously.Therefore, from the inspiratory capacity ratio increase of the 1st suction inlet 20 and the 2nd suction inlet 23, the air-breathing air-breathing wind path that the takes place 43 interior suction air-flows because of air entry 44 are reduced significantly.Thereby the rotary speed of air turbine 37 reduces or stops, and the rotary speed of the 1st rotating vane 63 and the 2nd rotating vane 64 also reduces or stops.
In order to remove the end of a thread of being wrapped on the 1st rotating vane 63 and the 2nd rotating vane 64 or hair etc. and will take off the 1st rotating vane 63 and the 2nd rotating vane 64 time, take off installed part 30 earlier and take off closure plate 29.Then, be fulcrum with the axial region 76 of the side of not establishing belt pulley 75, belt pulley 75 1 side direction below is moved, the axial region 76 of belt pulley 75 1 sides is taken off from bearing 77.Then, take off belt pulley 75 from the 2nd endless-belt 82b and the 3rd endless-belt 82c, and the axial region 76 that takes off as fulcrum from bearing 77 gets final product.Then do opposite action during installation.
Adopt above-mentioned example, when cleaning, guarantee to be located near the 1st suction inlet 20 between housing 15 downsides cleaning body chamber 18 the 1st and the cleaning body chamber 19 the 2nd negative pressure by the 1st rotating vane 63 that sets in cleaning body chamber 18 the 1st before and after the moving direction of suction inlet body 11 and the cleaning body chamber 19 the 2nd and the 2nd rotating vane 64 and ground.Therefore, make rotation be located at air turbines 37 rotations in the turbine room 38 in the air-breathing wind path 43 freely from the suction air-flow of suction inlet 44, and make the 1st rotating vane 63 and 64 rotations of the 2nd rotating vane, dust 90 is scanned out from ground.And effectively dust 90 is absorbed through sucking wind path 34 from the 1st suction inlet 20 and the 2nd suction inlet 23 that enough negative pressure are arranged.In addition, carry on housing 15 so that the downside of housing 15 when leaving the swept surface certain distance, the 1st suction inlet 20 and the 2nd suction inlet 23 of housing 15 downsides are opened.Therefore, from the soakage increase of the 1st suction inlet 20 and the 2nd suction inlet 23, the inspiratory capacity from air entry 44 reduces simultaneously.Thereby the rotating speed of air turbine 37 is reduced, and the rotary speed of the 1st rotating vane 63 and the 2nd rotating vane 64 is reduced.
Therefore, when in cleaning process, being positioned over ground,, can guarantee near the negative pressure 2 suction inlets 20,23, so can clean effectively by 2 rotating vanes 63,64 and ground face closure.Again because when on suction inlet body 11, carrying, the rotating speed of air turbine 37 reduces, and the reduction of the rotating speed of each rotating vane 63,64, so need not to be provided with the opening and closing device that opens and closes the gas leakage mouth, available simple structure easily reduces the rotating speed of each rotating vane 63,64, realizes miniaturization and easily.Also can alleviate the antitriptic wind sound that the rotation of each rotating vane 63,64 causes.
Owing to cleaning body chamber 18 the 1st is communicated with the 1st suction inlet 20, can easily the dust 90 that scans out be sucked from the 1st suction inlet 20 with enough negative pressure with communication air duct 28.That is, realized dual-use function, both had the gas leakage mouth function of the rotating speed reduction that makes air turbine 37 when on suction inlet body 11, carrying, had the suction inlet function that dust 90 is sucked again by simple structure.
Because this communication air duct 28 is the groove shape, thus with compare with the occasion of formation tubulars such as tube, can prevent that dust 90 from being tangled, be convenient to remove dust 90 etc., help maintaining.Certainly, this communication air duct 28 also can adopt the structure that utilizes tube that cleaning body chamber 18 the 1st is communicated with the 1st suction chamber 21.
Owing to cleaning body chamber 18 the 1st is communicated with the 1st suction inlet 20 with communication air duct 28, so when cleaning different types of swept surface, such as floor, tatami, carpet etc., the blocked state difference of the 1st suction inlet 20 and communication air duct 28, so negative pressure difference.Thereby, be variable from the soakage of the 1st suction inlet 20 and the 2nd suction inlet 23 and from the ratio between the soakage of air entry 44.When cleaning floor, from the soakage minimizing of air entry 44, the rotating speed of each rotating vane 63,64 is low, and when the cleaning carpet, from the soakage increase of air entry 44, the rotating speed of each rotating vane 63,64 increases.So need not to be provided with in addition ground detection, available simple structure changes the rotating speed of each rotating vane 63,64 according to Different Ground, can further improve cleaning work and sweeping efficiency.
Open in downstream one side owing to the 2nd suction inlet 23 again than the 45 more close communicating pipes 32 of intercommunicating pore that air-breathing wind path 43 was communicated with communicating pipe 32, so when on suction inlet body 11, carrying, less than leading to the inspiratory resistance of intercommunicating pore 45 through turbine room 38, and be positioned at the downstream from the suction resistance of the 2nd suction inlet 23 from air entry 44.Therefore, 23 performances of the 2nd suction inlet and gas leakage mouthful same effect, air-breathing from the 2nd suction inlet 23 easily, thus can further reduce the rotating speed of air turbine 37, and can reduce the rotating speed of each rotating vane 63,64 safely.
In addition, be clockwise spiral helicine the 1st rotating vane 63 and the 2nd rotating vane 64 and be reverse rightabout interior sideway swivel towards the hand of spiral, and make the 1st suction inlet 20 openings be in the hand of spiral one side under the rotation status at the 1st rotating vane 63, with the connection recess 27 of being located at the 1st suction inlet hand of spiral one side 20 opposite sides, the 2nd rotating vane 64, cleaning body chamber 18 the 1st and cleaning body chamber 19 the 2nd are communicated with.Therefore, become same direction by the direction of the inhalation power of the 1st suction inlet 20 suction and by the direction of the fabric blade part 71 of the 1st rotating vane and 72 guiding of twayblade portion, the dust 90 that scans out from ground successfully is inhaled into the 1st suction inlet 20 through communication air duct 28 because of the effect of attraction and fabric blade part 71 and twayblade portion 72.Again, the dust 90 that moves to the direction of leaving the 2nd suction inlet 23 owing to the blade part 67 of cleaning body chamber 19 the 2nd is drawn towards cleaning body chamber 18 the 1st through being communicated with recess 27, and is inhaled into the 1st suction inlet 20 from communication air duct 28.Therefore, can prevent that dust 90 is not inhaled into and remains in each cleaning body chamber 18,19, not only can improve the cleaning effect, and can alleviate the pollution of 90 pairs of suction inlet body 11 downsides of dust, can reduce the number of times of maintaining.
Because being communicated with recess 27 is groove shapes, so and communication air duct 28 same, and compare with the occasion of formation tubulars such as tube, can prevent that dust 90 from being tangled, be convenient to remove dust 90 etc., help maintaining.Certainly, this connection recess 27 also can adopt the structure that utilizes tube that cleaning body chamber 18 the 1st is communicated with cleaning body chamber 19 the 2nd.
In addition, the axis body 52 that makes the flat air turbine 37 of the vortex that can obtain big torque and is located at the 2nd bearing 49 that axle supports this axis body 52 position below the upper end of each rotating vane 63,64 between cleaning body chamber 18 the 1st and the cleaning body chamber 19 the 2nd between cleaning body chamber 18 the 1st and cleaning body chamber 19 the 2nd.Therefore, air turbine 37 is positioned on cleaning body chamber 18 the 1st and the cleaning body chamber 19 the 2nd with overlap condition.Thereby, both can obtain to for improve that the cleaning effect establishes a plurality of, for example 2 rotating vanes 63,64 are rotated and drive required big torque, the space that the space before and after the required moving direction of air turbine 37 is set and is provided as the required above-below direction of the 2nd bearing 49 of bearing can be dwindled again, miniaturization can be realized.Air turbine 37 has the cowling panel 54 of Xiang Yiduan expansion in addition, so can utilize the space of this cowling panel 54 expansions one side to be provided as the 1st bearing 47 of bearing, can further realize miniaturization.
The 1st suction inlet 20 is partial to an end opening from substantial middle portion, and forms up and the 1st suction chamber 21 adjacent in the face of the suction inlet chamber 24 the 2nd of communicating pipe 32 and that be communicated with, holds the central housing 39 of air turbine 37 in the substantial middle portion setting of housing 15.Therefore, not upper and lower settings from the suction wind path 34 of the 1st suction inlet 20 and the air-breathing wind path 43 that passes through turbine rooms 38 from air entry 44, so can dwindle the size of above-below direction, can further realize miniaturization.
On the other hand, owing on the 1st rotating vane 63, be provided with fabric blade part 71, so the erasable floor is up to the wall limit.And remedy because of the effect that blade part 67 that fabric blade part 71 reduces scans out dust is set by twayblade portion 72 is set, so when suction inlet body 11 moves forward and backward to scan out effect roughly the same, can further improve sweeping efficiency.
Again since the external diameter of the 1st rotating vane that is positioned at the front side less than the external diameter of the 2nd rotating vane, so can be arranged on forefront in the housing to the 1st rotating vane.Can dwindle the position of the 1st rotating vane kiss the earth and the distance of between the walls, can clean to the wall limit.
In addition, the 2nd rotating shaft 85 that tilts to set up the 2nd endless-belt 82b and between the 1st rotating vane 63 is positioned at the position that the 2nd rotating vane 64 1 lateral extents in the 1st rotating vane 63 and 64 centre positions of the 2nd rotating vane are grown.And the 3rd rotating shaft 86 that sets up to general horizontal direction the 3rd endless-belt 82c between the 2nd rotating vane 64 then is positioned at the short position of the 2nd rotating vane 64 1 lateral extents in the 1st rotating vane 63 and 64 centre positions of the 2nd rotating vane.Therefore, rotation in the time of can preventing to take off the 1st rotating vane 63 and the 2nd rotating vane 64 causes the 1st rotating vane 63 and the 2nd rotating vane 64 to brush up against the downside edge of opening of cleaning body chamber 18 the 1st and cleaning body chamber 19 the 2nd and hinders taking off, and is convenient to carry out the dismounting of the 1st rotating vane 63 and the 2nd rotating vane 64.
Also have the transmission device that the driving of air turbine 37 is transmitted to each rotating vane 63,64, i.e. the 1st endless-belt 82a and to drive conversion equipment 79 be to isolate to be arranged between cleaning body chamber 18 the 1st and the cleaning body chamber 19 the 2nd side opposite with suction wind path 43.Therefore the size that can dwindle above-below direction further realizes miniaturization.And with suck wind path 34 and isolate, through the conversion equipment 79 of overdriving, with the 2nd annular 82b and the 3rd endless-belt 82c the end of transmission of power to the 1 rotating vane 63 and the 2nd rotating vane 64.Therefore as the 1st endless-belt 82a of transmission device, drive the dust 90 that conversion equipment the 79, the 2nd endless-belt 82b and the 3rd endless-belt 82c can not be inhaled into and pollute, be convenient to maintaining.
Again, the air-breathing supply wind path 43a that supply with to suck air-flow to vortex off normal formula air turbine 37 vortex shape ground is that suction wind path 34 opposite sides at the 1st suction inlet 20 that is communicated with the cleaning body chamber 18 the 1st that is positioned at the moving direction front side form.Therefore it is not overlapping with air-breathing wind path 43a to suck wind path 34, further miniaturization.
And the air entry 44 of this air-breathing supply wind path 43a is in a side that derives communicating pipe 32, promptly at rear portion formation opening.Therefore, air entry 44 can not blocked by wall, furniture, curtain etc. in cleaning process, can more effectively make air turbine 37 rotations.Also can effectively utilize used space of axle supporting communicating pipe 32, Vorticose suction air-flow is supplied with to turbine room 38 in rectification limit, limit, can further improve the driving torque of air turbine 37 and realizes miniaturization.
Again, air entry 44 is the position upper shed formation that becomes the approximate vertical face at housing 15.Therefore can prevent that airborne trickle dust 90 is deposited in obstruction air entry 44 on the suction inlet body 11, can suppress the reduction of gettering efficiency, make air turbine 37 rotations effectively.
And air entry 44 is in a side that derives communicating pipe 32, promptly at rear portion formation opening.Therefore, air entry 44 can not blocked by wall, furniture, curtain etc. in cleaning process, can more effectively make air turbine 37 rotations.Also can effectively utilize axle supporting communicating pipes 32 used spaces and form air-breathing supply wind path 43a, rectification limit, limit is supplied with vortex shapes to turbine room 38 and is sucked air-flows, can further improve the driving torque of air turbine 37 and realizes miniaturization.
Again, air entry 44 is the position upper shed formation that becomes the approximate vertical face at housing 15.Therefore can prevent that airborne trickle dust 90 is deposited in obstruction air entry 44 on the suction inlet body 11, can suppress the reduction of gettering efficiency, make air turbine 37 rotations effectively.
In order to supply with the suction air-flow in the air turbine 37 vortex shape ground of air entry 44 in turbine room 38 that never stopped up by wall, furniture, curtain etc., air-breathing supply wind path 43a narrows down gradually in the front openings of turbine room 38 and from air entry 44, forms having of being communicated with and interferes the horn-like of function.Therefore can make the tapered air-breathing supply wind path 43a of that part of aperture area that arrives turbine room 38 will suck air-flow and carry out rectification by simple structure, can alleviate the antitriptic wind sound of air turbine 37 simultaneously, reduce noise.
