(embodiment)
Fig. 1 is the side perspective view of the hand drying unit of embodiments of the present invention.As shown in Figure 1, hand drying unit possesses drying chamber 2, nozzle 3 and electric blower 4.In drying chamber 2, from the insert port 1 of opening towards the outside, insert and extract hand 30 out.Nozzle 3 is sent air 6 towards drying chamber 2.Electric blower 4 is sent air 6 to nozzle 3, sends the air 6 of high pressure from nozzle 3.Hand drying unit is installed on the wall 51 in lavatory etc.The face side that user stands in hand drying unit is that user's side 52 is inserted hand 30.
Like this, nozzle 3 is that insert port center 1a is the drying chamber center line 7 configuration multiple rows 8 of the 5a of bottom center towards the center of the bottom surface 5 of drying chamber 2 with respect to the center from insert port 1, so that 30 30 integral body of hand while being inserted in drying chamber 2 of going smoothly blow to air 6 simultaneously.
The gabarit of hand drying unit is covered by front panel 20 and back casing 21.The drying chamber 2 that disposes nozzle 3 is positioned at a part for the gabarit of hand drying unit.Air amount 22 is sucked by electric blower 4 via filter 23, suction wind path 24, from ejection wind path 25, by face side air chamber 26 and rear side air chamber 27, from nozzle 3, blows out.The force-feeling sensor 28 on drying chamber 2 tops controls the break-make of electric blower 4.
Fig. 2 means the side perspective view of use state of hand being inserted to the hand drying unit of embodiments of the present invention.As shown in Figure 2, in the situation that make 30 oven dry such as the hand moistening because washing waits, hand 30 is inserted towards drying chamber 2 from insert port 1.Be located near the force-feeling sensor of insert port 1 28 chance hands 30 and make a response and make electric blower 4 runnings, from nozzle 3, blow out air 6 at a high speed.The dorsal side air stream vector 11 that the palmar side air stream vector 10 that palmar side upper nozzle 3a, palmar side lower nozzle 3b produce and dorsal side upper nozzle 3c, dorsal side lower nozzle 3d produce is opposed.Roughly meeting at right angles direction insertion extraction hand 30 with the opposed direction of each vector, remove the action of water.When hand 30 is inserted to drying chamber 2, the water droplet 33 of hand integral body easily concentrates on finger tip because of gravity.The water droplet 34 of finger tip is removed by the air 6 blowing out from palmar side lower nozzle 3b and dorsal side lower nozzle 3d when hand 30 is inserted into bottom surface 5.Not removed removing and the water droplet 34 of finger tip under residual and the water droplet 33 of hand integral body are removed and are dried by the air 6 blowing out from palmar side upper nozzle 3a and dorsal side upper nozzle 3c when carrying out the action that hand 30 is extracted out.
Fig. 3 means the simulation drawing that hand is inserted to the air-flow under the state of hand drying unit of embodiments of the present invention.Hand 30 is positioned at the position being clipped by palmar side air stream vector 10 and dorsal side air stream vector 11.In palmar side upper nozzle 3a and dorsal side upper nozzle 3c and palmar side lower nozzle 3b and dorsal side lower nozzle 3d position separately, air 6 collides with hand 30.It should be noted that, simulation of air flow condition is as follows: nozzle footpath:
near total nozzle number: pressure 48 (36 of upper nozzles, 12 of lower nozzle), nozzle: the width of about 7kPa, drying chamber: about 250mm, to the degree of depth (under nozzle) of the bottom surface of drying chamber: about 170mm.
By from insert port 1 towards the bottom surface 5 of drying chamber with the opposed position configuration nozzle 3 of multiple row 8, thereby from the pars intermedia of hand 30, to the water droplet of finger tip portion, by the nozzle 3 of first row (palmar side lower nozzle 3b and dorsal side lower nozzle 3d), removed.Utilize the later nozzle of secondary series 3 (palmar side upper nozzle 3a, palmar side lower nozzle 3b) to remove remaining water droplet.Tiny water-drop evaporation and being dried.That is to say, utilize the insertion of hand 30 once extract operation out and make to collide with hand 30 for twice from the air 6 of nozzle 3, thereby can shorten drying time, cut down the insertion of hand 30 and extract the activity duration out.
In addition, when hand 30 is inserted into drying chamber 2 depths, utilize the nozzle 3 of two row to make air 6 blow to hand 30 integral body simultaneously, therefore, can shorten drying time.
It should be noted that, palmar side lower nozzle 3b and the position of dorsal side lower nozzle 3d in drying chamber 2 are suitable for the finger root from hand 30 plays downside.Therefore, palmar side upper nozzle 3a, palmar side lower nozzle 3b are the more than 1/3 of length of hand 30 with respect to the distance expectation of palmar side lower nozzle 3b and dorsal side lower nozzle 3d respectively.According to the size of common hand 30, considering, is 50mm～200mm left and right.
Like this, hand drying unit according to the embodiment of the present invention, can make hand 30 dry at short notice.
It should be noted that, in embodiments of the present invention, the structures of nozzle 3 is upper and lower two row, in order to improve drying performance, can be also the structure of the nozzle 3 of multiple rows 8 more than three row.
Fig. 4 is the top view of observing from insert port from the different hand drying unit of embodiments of the present invention.As shown in Figure 4, the total of the aperture area of palmar side upper nozzle 3a and palmar side lower nozzle 3b is greater than the total of the aperture area of dorsal side upper nozzle 3c and dorsal side lower nozzle 3d.
That is, nozzle 3 be located at drying chamber 2 the user's side that approaches user face 2b and with the face 2a of the opposed side surface side of face 2b of user's side.And the total of the aperture area of the nozzle 3 of the face 2b of user's side is greater than the total of aperture area of nozzle 3 of the face 2a of side surface side.
At this, palmar side, owing to washing and adhering to more water with two hand rubbings, is compared with dorsal side, there is no pore and hydrophobicity is poor.Therefore,, if the hand drying unit of Fig. 4, water adheres to the air stream increase injection of more palmar side.Like this, the characteristic blow out air 6 according to palm, the back of the hand, can shorten drying time.
In addition, with regard to the nozzle 3 of multiple row 8, along with the bottom surface 5 towards drying chamber 2, reduce the configuration scope of nozzle 3.That is to say, lower nozzle configuration scope 43 is less than upper nozzle configuration scope 42.That is, nozzle 3 of each row of multiple row 8 along with from insert port 1 towards bottom surface 5 and configuration scope diminishes.
This with the width of palm along with the shape narrowing down towards finger tip is corresponding.That is, utilize said structure, only at necessary part centralized configuration nozzle 3, make effectively to blow to hand 30 from the air 6 of nozzle 3, thereby can realize the shortening of drying time in suitable ground mutually with the width of hand 30.
In addition, when two hands are inserted to drying chamber 2, axle A44 centered by the part that the middle finger of the right hand passes through, axle B45 centered by the part that the middle finger of left hand passes through.The horizontal stroke wide 46 of upper nozzle and the horizontal stroke wide 47 of lower nozzle with respect to central shaft A44, central shaft B45 respectively roughly symmetrical mode configure upper nozzle 3e and lower nozzle 3f.
That is, with respect to the face 2a of the face 2b of user's side and side surface side is divided into, two-part from insert port 1, towards bottom surface, 5 face center line 9 configure the nozzle 3 of each row of multiple row 8 symmetrically, and, in 9 both sides of face center line, also configure symmetrically.This is that roughly the shape of symmetry is corresponding centered by middle finger with palm.
Utilize said structure, with the width of the hand 30 of left and right mutually suitable ground only at necessary part centralized configuration nozzle 3.Therefore the part of, only passing through at hand 30 from the air 6 of nozzle 3 blows to hand.
In addition, when observing the opening of nozzle 3 from insert port 1, the opening of each nozzle 3 that is disposed at the same face side of drying chamber 2 is not disposed on the same straight line that inserts the direction of extracting hand out.That is to say, upper nozzle open centre axle 49 is not positioned on lower nozzle open centre axle 48.That is, the upper nozzle open centre axle 49 parallel with face center line 9 of each upper nozzle 3e that is disposed at top row 8a in nozzle 3 and the distance between face center line 9 are that upper nozzle is apart from 49a, 49b, 49c, 49d, 49e, 49f.In addition, the lower nozzle open centre axle 48 parallel with face center line 9 of each lower nozzle 3f that is disposed at lower columns 8b in nozzle 3 and the distance between face center line 9 are that lower nozzle is apart from 48a, 48b, 48c.Now, upper nozzle is completely different apart from 48a, 48b, 48c apart from 49a, 49b, 49c, 49d, 49e, 49f and lower nozzle.
Utilize said structure, in insert extracting the process of hand 30 out, the direction that extract out with respect to the insertion of hand 30 position of the nozzle 3 of each row staggers, and therefore, there will not be the air 6 of waste to blow to and the situation of same section of once having removed the hand 30 of water droplet.Therefore, the hand drying unit of embodiments of the present invention can not produce dries inequality, can make at short notice hand dry.In addition, the hand drying unit of embodiments of the present invention suppresses the total of the aperture area of nozzle 3, does not reduce the blast from nozzle 3, can make at short notice hand dry, and can be low consumption electric power.
Fig. 5 is the side perspective view of the another different hand drying unit of embodiments of the present invention.As shown in Figure 5, palmar side air stream vector 10 and dorsal side air stream vector 11 are roughly the same plane.That is the air-flow, blowing out from palmar side upper nozzle 3a and the air-flow blowing out from dorsal side upper nozzle 3c collide from front.In the same manner, the air-flow blowing out from palmar side lower nozzle 3b and the air-flow blowing out from dorsal side lower nozzle 3d collide from front.In other words, to be located at each upper nozzle 3e of face 2b of user's side and the air stream vector of lower nozzle 3f be palmar side air stream vector 10, and to be that dorsal side air stream vector 11 staggers relative in 180 degree with being located at each upper nozzle 3e of face 2a of side surface side and the air stream vector of lower nozzle 3f.
Utilize said structure, the central portion collision from the opposed nozzle 3 of drying chamber 2 air 6 out at drying chamber 2.Therefore, evenly blow to the roughly the same height of palmar side and dorsal side from the air 6 of both sides, the water droplet that can prevent from being attached to palmar side and dorsal side spreads and peels off water droplet from hand 30 to the opposition side of hand 30.In addition, can not reduce the impetus of opposed collision with the air 6 of hand 30 collisions.Consequently, the buzz that the turbulent flow producing in the time of preventing from colliding with wall with blowing out the drying chamber 2 of side opposition side causes.
According to the hand drying unit of such structure, can make at short notice hand dry, can realize low noise.
