(air stream)
Air stream in the air cleaner 1 below is described.At first, as shown in Figure 3, by being rotated by Motor Drive Sirocco fan 12, produce negative pressure in the space of the main box 2 at Sirocco fan 12 rears, indoor air is inhaled in the main box 2 by being positioned at the suction inlet 6 on the main box 2.
As shown in Figure 3, when being inhaled into air in the main box 2 successively by dust-collecting filter 10 and humidifying filter 11, being carried out control of dust and processing and add wet process, and by the set intercommunicating pore 14 of downside air-supply wind path 13A.Then, as shown in Figure 3 and Figure 4, the air by intercommunicating pore 14 blows out laterally from the side face of Sirocco fan 12.The air that blows out like this is imported into blow-off outlet 7 by air-supply wind path 13, and the ion that produces machine 15 generations with ion is delivered to indoor.Represent above-mentioned a series of air stream with arrow (hollow) among Fig. 3, Fig. 4.
The blow-off outlet 7 of air cleaner 1 is separated part 71 and is divided into the first blow-off outlet 72 and the second blow-off outlet 73 these two blow-off outlets.The air that is directed into blow-off outlet 7 towards the back of air cleaner 1 side and blow out upward, and is blown out to front face side from the second blow-off outlet 73 from the first blow-off outlet 72.
As shown in Figure 3 and Figure 4, in the above-mentioned air cleaner 1, the left side wall 133 of upside air-supply wind path 13B from the peristome 131A in week facial 131 circumferential one distolateral, extend and be connected with blow-off outlet 7 in the direction of the cardinal principle tangent line S of the circumference of Sirocco fan 12.Right side wall 134 is relative with left side wall 133, and extends from another circumferential distolateral mode with sidewall 133 inclinations left in week facial 131, and is connected with blow-off outlet 7.Sirocco fan 12 rotates along the clockwise direction among Fig. 4, and the air that utilizes the centrifugal force of Sirocco fan 12 to send to blow-off outlet 7 is many in right side wall 134 1 crosswind quantitative changes, and is few in left side wall 133 1 crosswind quantitative changes.So air to the right sidewall 134 1 sides blows out with relative high wind speed, sidewall 133 1 sides blow out with relatively low wind speed left.At this moment, when the air that blows out with relative high wind speed from Sirocco fan 12 flows along right side wall 134, utilize this right side wall 134 towards the inclination in left side, produce the composition towards the air stream of left side wall 133 1 sides.
Like this, owing to blowing out to blow-off outlet 7 after being rectified in air-supply wind path 13 from the air of Sirocco fan 12, the Air blowing amount of right side wall 134 1 sides of air-supply wind path 13 is inhibited more than the situation of the Air blowing amount of left side wall 133 1 sides, so can be across the long side direction of blow-off outlet 7 blow out air more equably.In addition, wind after the rectification is by near the ion generation machine 15, and in the situation that a plurality of ions that do not have to configure side by side on the turbulent contact ions generation machine 15 produce electrodes, thereby producing the ion of certain electrode generation of machine 15, ion in the situation that can not interfere with the ion of other electrodes, decay, is released.
In addition, since left side wall 133 from the peristome 131A in week facial 131 circumferential one distolateral, roughly extend and be connected with blow-off outlet 7 in the direction of the cardinal principle tangent line S of the circumference of Sirocco fan 12, right side wall 134 is relative with left side wall 133, and distolateral from circumferential another of the peristome 131A in week facial 131, the mode that tilts with sidewall left 133 is extended and is connected with blow-off outlet 7, so the Width of the left and right directions of the wind path 13 of blowing narrowed down in the past.Like this, can improve the wind speed of air-supply in the wind path 13.The ion that the air high speed contact ions that blows out from Sirocco fan 12 produces machine 15 produces electrode, produces the ion that machine 15 generates from ion and can efficiently be discharged into indoor.
Air cleaner 1 according to present embodiment, front side wall 135 and rear wall 136 are to omit the state of low dip towards the back side, 13A closely extends mutually to blow-off outlet 7 from downside air-supply wind path, ion produce machine 15 be installed in intercommunicating pore 14 roughly directly over and blow-off outlet 7 roughly under, on the part of rear wall 136.Shown in the arrow (hollow) of Fig. 3, because in rear wall 136 1 sides, Sirocco fan 12 is near apart from suction inlet 6, thus blast relatively uprise because in front side wall 135 1 sides, Sirocco fan 12 is far away apart from suction inlet 6, so the blast relative reduce.Like this, the air of sending from Sirocco fan 12 produces electrode with the ion that relative high speed contact is installed in the ion generation machine 15 on the rear wall 136.The ion that produces machine 15 generations from ion can further efficiently be discharged into indoor.
In addition, as shown in Figure 3, blow-off outlet 7 is separated part 71 and is divided into the first blow-off outlet 72 and the second blow-off outlet 73 these two blow-off outlets.Send the rear air that is directed into the first blow-off outlet 72 along rear wall 136 from Sirocco fan 12, with relatively high wind speed towards the back of air cleaner 1 side and blow out upward, and be directed to the air of the second blow-off outlet 73 along front side wall 135, blow out with the front face side of relatively low wind speed to air cleaner 1.
Fig. 5 is the key diagram that schematically shows the air stream that the present embodiment air cleaner produces in the room.As shown in Figure 5, when air cleaner 1 with suction inlet, when to be back side be arranged in the room to the mode of wall,, be reflected after running into wall with the air that relatively high wind speed blows side out to the back of air cleaner 1 from blow-off outlet, blow out to the central authorities in room.Like this, air can be blown to the distant place in room.In addition, utilize Sirocco fan to rotate the inhalation power that produces, with the air intake air cleaner 1 in the room, can further improve flowing of air.By adopting the air cleaner 1 of present embodiment, can quick adsorption to the dust of distant place, room.
