(2) structure of blow-off outlet periphery
The amplification cross section of blow-off outlet 30 periphery when cutting open with the face vertical with the left and right directions of air purifier 10 has been shown in Fig. 2.The blade part 41 of the tabular of horizontal blade 40 extends longer in the lateral direction.That extend about the upside of the blade part 41 shown in Fig. 2 is the first limit 41a, and that extend about the downside of the blade part 41 shown in Fig. 2 is Second Edge 41b.At blow-off outlet 30, the rotating shaft 51 for support horizontal blade 40 is outstanding towards right from the left surface 31 of blow-off outlet 30.This rotating shaft 51 utilizes stepping motor (not shown) to rotate.In addition, fulcrum (not shown) is outstanding from the right flank (not shown) of blow-off outlet 30 towards left on the extended line of rotating shaft 51.In the mode of being clamped by this rotating shaft 51 and fulcrum, horizontal blade 40 is fixedly attached to rotating shaft 51, therefore, horizontal blade 40 rotates in concert with the rotation of rotating shaft 51.
Be provided with bearing portion 42 at horizontal blade 40, this bearing portion 42 has the installing hole 43 inserted for rotating shaft 51.Bearing portion 42 is formed near the Second Edge 41b of horizontal blade 40.Horizontal blade 40 is configured to the inclined plane 33 of its Second Edge 41b along the rear side of blow-off outlet 30.In addition, it is modes in order to not contact with blow-off outlet 30 with the Second Edge 41b of blade part 41 that the rear side of blow-off outlet 30 is formed as inclined plane 33, and horizontal blade 40 is successfully rotated centered by rotating shaft 51.
The air-flow that to make because of Coanda effect (coanda effect) from blow-off outlet 30 is formed with along the flexure plane 35 of the housing 11 of air purifier 10 at the front side on the limit 32 of the front side of blow-off outlet 30.Blow-off outlet 30 and flexure plane 35 can be one, also can be made up of different component.Flexure plane 35 bends to convex upward, and is the shape of arc-shaped in cross section.The front side of flexure plane 35 and the top 12 of housing 11 continuously, and make the clean air advanced along flexure plane 35 blow out towards diagonally forward when not hindered by housing 11,
Horizontal blade 40 blocks blow-off outlet 30 when air purifier 10 shuts down.Therefore, from the state of Fig. 2, horizontal blade 40 is rotated counterclockwise, till near the limit 32 in the front of the first limit 41a arrival blow-off outlet 30 of blade part 41.
(3) switching of the blow-off direction of clean air
Use Fig. 2 and Fig. 3, the switching of the blow-off direction of the clean air that the blow-off outlet 30 from air purifier 10 blows out is described.Also show the amplification cross section of blow-off outlet 30 periphery of air purifier 10 in Fig. 3 identically with Fig. 2.Air purifier 10 shown in Fig. 3 and the difference of the state of Fig. 2 are the angles of horizontal blade 40.Compared with the state of the horizontal blade 40 of Fig. 2, the horizontal blade 40 of Fig. 3 is rotated counterclockwise and makes the limit 32 of the first limit 41a near the front side of blow-off outlet 30 of blade part 41.That is, Fig. 2 shows blowing up state, and Fig. 3 shows fore blow state.
Horizontal blade 40 shown in Fig. 2 is in the state erected up and down, and the direction of the clean air blown out upward from blow-off outlet 30 is parallel with blade part 41, and therefore, the clean air of blowout applies pressure to the inner surface of the blade part 41 of horizontal blade 40 hardly.In other words, the clean air blown out from blow-off outlet 30 can not produce crushing because of horizontal blade 40.Now, near the limit 32 of the front side of blow-off outlet 30 flowing clean air in, because of make the flow direction become along flexure plane 35 towards Coanda effect and make from blow-off outlet 30 blow out clean air as shown in arrow A r5 slightly towards top rake.But the top of blow-off outlet 30 is open, and therefore, as shown in arrow A r5, clean air mainly blows out upward forcefully.
In addition, in the condition shown in figure 3, horizontal blade 40 tilts towards the front side of blow-off outlet 30, and therefore, the path regarding blow-off outlet 30 as bends towards diagonally forward.Such as, now, from identical or larger than this distance D1 with the distance D1 of the front and back of blow-off outlet 30 with the distance D2 of blow-off outlet 30 continuous print flexure plane 35 to blade part 41.Therefore, even if the blade part 41 of horizontal blade 40 tilts and covers slightly above blow-off outlet 30, the crushing produced because of horizontal blade 40 also can be suppressed to become large.In addition, the path of blow-off outlet 30 bends towards diagonally forward because of horizontal blade 40, and therefore, the air-flow along the clean air of flexure plane 35 flowing increases, and the Coanda effect produced by flexure plane 35 strengthens.By this, as shown in the arrow A r6 of Fig. 3, the direction that the air-flow of clean air tilts than horizontal blade 40 bends further forward.
About this point, compare with the existing air purifier 100 shown in Fig. 4, be described further on one side.In the existing air purifier 100 shown in Fig. 4, the part corresponding with the air purifier 10 shown in Fig. 1 to Fig. 3 is marked to the symbol of No. 100 sections, such as by the part label symbol 140 corresponding with the horizontal blade 40 of Fig. 2, omit the detailed description of existing air purifier 100 each several part.In the existing situation shown in Fig. 4, when rotating counterclockwise when horizontal blade 140 and tilt towards the limit 132 of the front side of blow-off outlet 130, the blow-off direction of the clean air blown out upward tilts slightly along blade part 141 as shown in arrow A r7.But, owing to not producing Coanda effect, therefore, produce the air-flow of the clean air along housing 111 hardly, can not the blow-off direction of the such clean air of fore blow state as shown in Figure 3 significantly tilt forward.Even if like this, because the distance D3 of limit 132 to blade part 141 of the front side from blow-off outlet 130 is little compared with the distance D1 of the front and back of blow-off outlet 130, therefore crushing can increase.Consequently, in existing air purifier 100, even if make horizontal blade 140 tilt forward, the air quantity of the air-flow of clean air forward also increases hardly.
(4) feature
The housing 11 (example of basket) of air purifier 10 is formed a blow-off outlet 30 in order to blow out clean air and opening upward.In addition, housing 11 is formed with flexure plane 35 continuously with the limit 32 of the front side of blow-off outlet 30, this flexure plane 35 flows along it because of Coanda effect for the air-flow from blow-off outlet 30.Horizontal blade 40 (the first wind direction changes an example of component) is configured to be between posture shown in Fig. 3 that the posture (example of the prime during blowing up state mainly making clean air blow out upward) shown in Fig. 2 of erecting up and down and blade part 41 tilt (make of second when producing more than blowing up state because of Coanda effect along the air-flow of flexure plane 35 and blow out the fore blow state of clean air towards diagonally forward routine) at blade part 41 and switches.
As mentioned above, when horizontal blade 40 is switched to the posture of Fig. 3 from the posture of Fig. 2, produce more because of Coanda effect along the air-flow of flexure plane 35, blow out towards diagonally forward by this, therefore, the crushing increase compared with blowing up state when blowing out towards diagonally forward can be suppressed.
In addition, horizontal blade 40 is configured at the inclined plane 33 of the rear side relative with the limit 32 of the front side of blow-off outlet 30, and has the inner surface (the first wind direction changes an example of the first type surface of component) of blade part 41, and this inner surface flows along it for clean air.In the posture of Fig. 3, than the mode of position near the limit 32 of the front side of blow-off outlet 30 of the first limit 41a in the posture of Fig. 2, the inner surface of blade part 41 is tilted with the position of the first limit 41a of blade part 41 (example of the upper end of first type surface).By this, utilize horizontal blade 40 that the flowing of clean air is bent towards flexure plane 35, with increase because of Coanda effect along the throughput of flexure plane 35, therefore, significantly can't increase crushing when blowing out towards diagonally forward to make air-flow bend compared with blowing up state.Such horizontal blade 40 makes air-flow bend, and therefore, can suppress the increase of crushing, and increases the throughput based on Coanda effect along flexure plane 35, to increase the air capacity blown out forward.

(13-1) variation 3A
In the above-described 3rd embodiment, wind direction adjusting plate 62 has the larger shape covering flexure plane 35 entirety, but wind direction adjusting plate 62 also can be such primary structural component overlapping with the local of flexure plane 35.As long as wind direction adjusting plate 62 can hinder the size of the degree of the air-flow along flexure plane 35, the effect identical with the effect of above-mentioned 3rd embodiment just can be played.
(13-2) variation 3B
In the above-described 3rd embodiment, the example switched between blowing up state and fore blow state only arranging horizontal blade 40 at blow-off outlet 30 is illustrated, but except horizontal blade 40, other blade changing wind direction in the lateral direction also can be set.
(13-3) variation 3C
In the above-described 3rd embodiment, use the example of Coanda effect to be illustrated to use horizontal blade 40 and wind direction adjusting plate 62, but also can omit horizontal blade 40 and only regulate Coanda effect with wind direction adjusting plate 62.
