Detailed description of the invention

Hereinafter, with reference to the accompanying drawings of embodiments of the present invention.

(embodiment)

Fig. 1 is the side cut away view of the drying apparatus for hands of embodiments of the present invention, and Fig. 2 is the figure of the general example of this drying apparatus for hands.As depicted in figs. 1 and 2, drying apparatus for hands comprises: the hand hothouse 2 from the hand insert port 1 of outside 22 opening to side, front 20, hand 5 being extracted out insertion; The nozzle 3 of the pressure-air 23 of 0.5kPa ~ 15kPa is blown out to hand hothouse 2; With the electric blower 4 of discharging pressure-air 23 to nozzle 3.

This drying apparatus for hands is installed on the wall 16 etc. of Dressing Room.Like this, user stands in the front of drying apparatus for hands, inserts hand 5.The opening of hand hothouse 2 is arranged at front relative to user.Hand 5 inserts along the side, front 20 from hand hothouse 2 to the direction of insertion 6 that inboard 21 go.

The sensor 7 of the insertion detecting hand 5 is provided with at the central portion of the upper surface of hand hothouse 2.When wetting hand 5 after washing one's hands inserts hand hothouse 2, by sensor 7 detect sell 5 insertion, by this detection, electric blower 4 operates.When electric blower 4 operates, the suction air 9 attracted from suction inlet 8 through filter 10, suck wind path 11 and flow into the inside of drying apparatus for hands.Then, suck air 9 and boosted by electric blower 4 and form blowout air-flow 12, discharge from nozzle 3.Blow away the moisture of the wetting hand 5 after washing one's hands from the blowout air-flow 12 of nozzle 3 discharge, make it evaporate.Extract hand 5 out from hand hothouse 2, sensor 7 do not have detect sell 5 insertion time, electric blower 4 stops.

As shown in Figure 2, in drying apparatus for hands, the several seconds after hand 5 is inserted into hothouse 2, the palm of two hands opens the blowout hole 13 close to nozzle 3.Then, rotation limit, hand 5 limit is extracted out and is inserted, and blows away large water droplet by the blowout air-flow 12 of nozzle 3.After this, residual little water droplet, the palm of two hands wiping each other in drying apparatus for hands, rubs, and water droplet in palm integral extension, and is blown away by blowout air-flow 12, evaporated.

Herein, as shown in Figure 1, the nozzle 3 being arranged at the upper surface of hand hothouse 2 comprises first jet 3a and second nozzle 3b.First jet 3a arranges in the horizontal direction column-shaped orthogonal with direction of insertion 6 near hand insert port 1.Second nozzle 3b relative to hand insert port 1 than first jet 3a by inboard 21 position and first jet 3a separate predetermined distance 24 ground and arrange.Sensor 7 is configured between first jet 3a and second nozzle 3b.The blowout air-flow 12 boosted by electric blower 4 splits into first jet blowout air-flow 12a and second nozzle blowout air-flow 12b in blowout wind path 18.Second nozzle blowout air-flow 12b as pressure-air 23 blows out to regulation region 14 point-like near the central authorities of hand hothouse 2.Herein, the regulation region 14 near the central authorities of the hand hothouse 2 of second nozzle blowout air-flow 12b blowout is the region of the neighbouring part of central authorities of hand hothouse 2, for blowing out the region of region by inboard 21 of air-flow 12a blowout than first jet.

By said structure, utilize the first jet blowout air-flow 12a near hand insert port 1, blow away large water droplet when the extraction insert action of hand 5.Then, under the state that hand 5 inserts in hothouse 2 in one's hands, hand 5 rub action time, make air-flow blow to the hand 5 such as finger tip 51 side and the back of the hand to the hand 5 rubbed overall.Like this, little water droplet residual after large water droplet is blown away effectively is blown away and is evaporated.Herein, second nozzle blowout air-flow 12b does not disturb first jet to blow out air-flow 12a, under the state keeping directionality and wind speed, blows to the hand 5 of insertion.

Fig. 3 is the front elevation of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 3, second nozzle 3b is made up of the multiple second nozzles blowout holes 43 comprising the first blowout hole 3e and second blowout hole 3f.First blowout hole 3e is positioned at one end among multiple second nozzle blowout hole 43.In addition, the second blowout hole 3f is positioned at the other end among multiple second nozzle blowout hole 43.And the second nozzle blowout distance between borehole 25 of the first blowout hole 3e and second blowout hole 3f is preferably more than 20mm below 150mm.In other words, second nozzle 3b is preferably made up of the multiple second nozzles blowout holes 43 in the scope being arranged on more than 20mm below 150mm.

This is due to when hand 5 is rubbed by the central authorities of hand hothouse 2, and second nozzle blowout air-flow 12b only concentrates and blows to the hand 5 rubbed and make little water-drop evaporation efficiently.When second nozzle blowout distance between borehole 25 is within 150mm, air-flow concentrates hand 5 entirety blowing to and rub fully.But the Breadth Maximum 42 of the hand 5 rubbed, considers that the size of general hand 5 is about 20mm ~ 100mm.In order to reduce the unnecessary air-flow not blowing to the hand 5 rubbed, more preferably second nozzle blowout distance between borehole 25 is more than 20mm below 100mm.

According to said structure, time near the central authorities that hand 5 inserts hothouse 2 in one's hands, second nozzle blowout air-flow 12b concentrates the hand 5 blowing to and rub.Consequently, the blowout air-flow not blowing to hand 5 can be reduced, suppress the energy of waste.

In addition, the blow-off direction that multiple second nozzle blowout holes 43 of preferred second nozzle 3b are respective is parallel to each other.Consequently, each second nozzle blowout air-flow 12b of second nozzle 3b does not conflict mutually, the energy loss that the conflict of air-flow can be suppressed to cause and the generation of noise.

In addition, being shorter than from the blowout wind path 18 till the blow-off outlet of electric blower 4 to second nozzle 3b from the blowout wind path 18 till the blow-off outlet of electric blower 4 to first jet 3a shown in Fig. 1.Like this, the wind speed of the first jet blowout air-flow 12a of preferred first jet 3a is greater than the wind speed of the second nozzle blowout air-flow 12b of second nozzle 3b.Consequently, large water droplet is easily blown away, and drying time when therefore the extraction of hand 5 is inserted shortens.

In addition, as shown in Figure 1, preferably heater 15 is set in the midway of the blowout wind path 18 gone from electric blower 4 to second nozzle 3b, heater 15 and electric blower 4 on-off linkedly.By heater 15, the blowout temperature of the second nozzle blowout air-flow 12b of second nozzle 3b, higher than the blowout temperature of the first jet blowout air-flow 12a of first jet 3a, is inserted rear residual little water droplet in the extraction of hand 5 and is effectively evaporated.

In addition, the predetermined distance 24 of first jet 3a and second nozzle 3b is preferably more than 50mm below 100mm in direction of insertion 6.

Consequently, first jet blowout air-flow 12a and second nozzle blowout air-flow 12b does not influence each other, under the state of the speed of guarantee and temperature, arrive the hand 5 inserting hothouse 2 in one's hands.When predetermined distance 24 is lower than 50mm, the blowout air-flow 12 of the high wind speed of first jet 3a and second nozzle 3b attracts the blowout air-flow 12 of the opposing party.Therefore, before blowout air-flow 12 arrives the hand 5 rubbed, be formed as being partial to the air-flow of the blow-off direction of a wherein side, be difficult to blow to hand 5 overall.

In addition, when predetermined distance 24 is more than 50mm, can guarantees that sensor 7 is configured at the space between first jet 3a and second nozzle 3b, the structure of drying apparatus for hands can be simplified.

In addition, when predetermined distance 24 is more than 100mm, hand hothouse 2 becomes large, and air-flow only blows to finger tip 51 and wrist, produces uneven drying.Consider the size of general hand 5, predetermined distance 24 is below 100mm.Therefore, first jet blowout air-flow 12a and second nozzle blowout air-flow 12b does not influence each other, and under the state of guarantor tropism, speed and temperature, arrive the hand 5 inserting hothouse 2 in one's hands, when rubbing hand 5, water droplet is effectively blown away, evaporates.Like this, the drying apparatus for hands of embodiments of the present invention can realize low power consumption, low noise and shorten drying time of hand 5.

In addition, in present embodiment, the blowout air-flow 12 towards first jet 3a is shunted in identical blowout wind path 18 with the blowout air-flow 12 towards second nozzle 3b.But the wind path towards the blowout air-flow 12 of second nozzle 3b is arranged respectively with the wind path of the blowout air-flow 12 towards first jet 3a, and action effect does not have difference yet.

In addition, in present embodiment, the midway of the blowout wind path 18 towards second nozzle 3b is provided with heater 15.But the mode that also can flow to first jet 3a and second nozzle 3b with the blowout air-flow 12 that have passed heater 15 configures heater 15.Now, second nozzle is blown out to the heat of air-flow 12b applying more than the heat applied first jet blowout air-flow 12a.And second nozzle blowout air-flow 12b is formed as the air-flow higher than first jet blowout air-flow 12a temperature.

Fig. 4 is the side cut away view of the first different modes of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 4, the blow-off direction of preferred second nozzle 3b tilts towards the inboard 21 of hand hothouse 2.

According to said structure, for the finger tip 51 of the hand 5 rubbed, water droplet is flowing from the direction that finger tip 51 blows away by second nozzle blowout air-flow 12b.Therefore, little water droplet residual after large water droplet is blown away effectively is blown away and is evaporated, and the drying time of hand 5 shortens.

Fig. 5 is the hand hothouse top view of the second different modes of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 5, when drying apparatus for hands uses under the warm environment of 30 DEG C ~ 50 DEG C, the first jet aperture area 61a of preferred first jet 3a is greater than the second nozzle aperture area 61b of second nozzle 3b.

According to said structure, the air quantity of first jet blowout air-flow 12a blows out the air quantity of air-flow 12b more than second nozzle.Therefore, during the extraction insert action of the hand 5 of Fig. 1, large water droplet is easily blown away.On the other hand, the air quantity of second nozzle blowout air-flow 12b reduces, and the output for the heater 15 of Fig. 1 of warm air air-flow is suppressed, even if therefore drying apparatus for hands uses and also do not damage use sense under warm environment, drying time shortens.

Fig. 6 is the hand hothouse top view of the 3rd different modes of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 6, when drying apparatus for hands uses under the environment of cold of 0 DEG C ~ 20 DEG C, the second nozzle aperture area 61b of preferred second nozzle 3b is greater than the first jet aperture area 61a of first jet 3a.

According to said structure, the air quantity of second nozzle blowout air-flow 12b blows out the air quantity of air-flow 12a more than first jet.Therefore, after the extraction insert action of hand 5, residual little water droplet is easily blown away and evaporates.On the other hand, because first jet aperture area 61a is little, so the output of the electric blower 4 of Fig. 1 is suppressed, also do not damage use sense even if use under the environment of cold, drying time shortens.

Like this, the drying apparatus for hands of present embodiment, does not damage use sense under warm environment or under the environment of cold, and low power consumption and drying time shorten.

In addition, as shown in Figure 6, the rectangular slot shape of can be direction of insertion 6 be the first jet blowout hole 71 of first jet 3a minor face.

According to said structure, the wind speed of first jet blowout air-flow 12a is maintained, and the area that when extraction of the hand 5 of Fig. 1 is inserted, air-flow blows to increases.Therefore, when the extraction of hand 5 is inserted, large water droplet is more effectively blown away.In addition, after the extraction of hand 5 is inserted, little water droplet residual on hand 5 also reduces, and the drying time of therefore rubbing when hand 5 makes hand dry can not be elongated.And second nozzle aperture area 61b reduces, and the output of the electric blower 4 of Fig. 1 is suppressed, low power consumption and the drying time of hand 5 shorten.

Fig. 7 is the hand hothouse top view of the 4th different modes of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 7, second nozzle 3b is inclined relative to direction of insertion 6.In addition, second nozzle 3b comprises right side second nozzle 3c and left side second nozzle 3d.

Second nozzle 3b is to go from the mediad end of hand hothouse 2 relative to direction of insertion 6 and to go the mode of fan out inclined to inboard 21.In other words, right side second nozzle 3c is in the direction configuration relative to direction of insertion 6 inboard inclination to the right, and left side second nozzle 3d is in the direction configuration relative to direction of insertion 6 inboard inclination left.Right side second nozzle 3c and left side second nozzle 3d is not limited to symmetrical, but preferably symmetrically configures.Like this, from side, front 20 along direction of insertion 6, right side second nozzle 3c is arranged at the central authorities position on the right side than hand hothouse 2, and left side second nozzle 3d is arranged at the position of the side that to keep left than the central authorities of hand hothouse 2.

The angle of inclination of inclined second nozzle 3b now, the angle θ namely gone from the width of hand hothouse 2 towards inboard 21 is 30 ° ~ 60 °.Angle θ considers that when hand hothouse 2 takes out the hand 5 of Fig. 1, effectively blow away water droplet from the side of hand 5 towards incline direction determines.

Herein, blow to because second nozzle blowout air-flow 12b only concentrates the hand 5 rubbed in the central authorities of hand hothouse 2, therefore the second nozzle spacing 26 of right side second nozzle 3c and left side second nozzle 3d is more than 50mm below 150mm.But, also can second nozzle 3b blow-off direction tilt, the blow-off direction of right side second nozzle 3c and left side second nozzle 3d is respectively towards the middle section of hand hothouse 2, and second nozzle spacing 26 also can be greater than 150mm.

In addition, the sensor 7 for detecting hand 5 is had at the spatial placement of the central authorities of hand hothouse 2 upper surface clipped by second nozzle 3b.Sensor 7 is arranged between the second nozzle 3c and left side second nozzle 3d of right side.

In addition, as shown in Figure 7, the predetermined distance 24 of preferred second nozzle 3b and first jet 3a is more than 50mm below 100mm, does not influence each other to make first jet blowout air-flow 12a and second nozzle blowout air-flow 12b.But, by making the blow-off direction of second nozzle 3b tilt with the blow-off direction of second nozzle 3b relative to the mode of direction of insertion 6 towards inboard 21, same effect can be obtained.Therefore, predetermined distance 24 also can less than 50mm.But now, in order to make each air-flow not influence each other, preferred predetermined distance 24 is more than 20mm.

Take vertical direction as benchmark, viewed from front during hand hothouse 2, the blow-off direction of preferred first jet blowout air-flow 12a from side, front 20 to inboard 21 going ± scope of 5 ° in.Its reason is as described below.When being tilted beyond 5 ° to side, front 20, the water droplet blown away when the extraction of hand 5 is inserted flies to towards user, and therefore user may be got wet.In addition, when being tilted beyond 5 ° to inboard 21, in order to blow to the blowout air-flow of first jet 3a, need the depths of hand 5 being inserted hothouse 2 in one's hands, ease of use is deteriorated.

Take vertical direction as benchmark, viewed from front during hand hothouse 2, the blow-off direction of preferred second nozzle blowout air-flow 12b goes in the scope of 5 ° ~ 25 ° from side, front 20 to inboard 21.Its reason is as described below.In order to not make water droplet fly to user, preferably tilt more than 5 ° to inboard 21.In addition, in order to when hand 5 is inserted hothouse 2 in one's hands, hand 5 does not contact with the wall of the inboard 21 of hand hothouse 2, preferably tilts less than 25 ° to inboard 21.

In order to make first jet blowout air-flow 12a and second nozzle blowout air-flow 12b not influence each other, the blow-off direction of the blow-off direction of first jet 3a and second nozzle 3b is blown out to the direction be separated from each other.

According to said structure, when extracting hand 5 from hand hothouse 2, second nozzle blowout air-flow 12b tilts to blow in the mode of crossing palm or the back of the hand, therefore effectively blows away water droplet.

Specifically, when extracting hand 5 from hand hothouse 2, make the back of the hand towards time above, the water droplet being attached to hand 5 is concentrated from the root of little finger of toe to the front end of thumb or forefinger, effectively blows away water droplet.In addition, when extracting hand 5 from hand hothouse 2, make palm towards time above, the water droplet being attached to hand 5 is concentrated from the root of thumb to the front end of little finger of toe or the third finger, effectively blows away water droplet.

In addition, do not blow away and residual water droplet concentrates on the side of hand 5, therefore, rub hand 5 dry time water droplet is evaporated effectively, therefore shorten drying time.

In addition, the shape of second nozzle 3b is rectangular slot, but is not limited to this.Such as, second nozzle 3b, by inclined for multiple holes of waveform, clavate, circle, polygon or other shape, also can obtain same effect.

Fig. 8 is the hand hothouse top view of the 5th different modes of the drying apparatus for hands of embodiments of the present invention.As shown in Figure 8, second nozzle 3b (right side second nozzle 3c and left side second nozzle 3d) is to go from the end of hand hothouse 2 to central authorities relative to direction of insertion 6 and to go the mode that reduces inclined to inboard 21.In other words, the direction configuration that right side second nozzle 3c is tilting towards portion in left side relative to direction of insertion 6, left side second nozzle 3d is in the direction configuration of tilting towards portion in right side relative to direction of insertion 6.Right side second nozzle 3c and left side second nozzle 3d preferably symmetrically configures about direction of insertion 6.

The angle of inclination of inclined second nozzle 3b now, the angle θ namely gone from the width of hand hothouse 2 towards side, front 20 is 30 ° ~ 60 °.Angle θ considers that when hand hothouse 2 takes out the hand 5 of Fig. 1, effectively blow away water droplet from the side adipping of hand 5 determines.

Herein, blow to because second nozzle blowout air-flow 12b only concentrates the hand 5 rubbed in the central authorities of hand hothouse 2, therefore the second nozzle spacing 26 of right side second nozzle 3c and left side second nozzle 3d is more than 50mm below 150mm.But, also can second nozzle 3b blow-off direction tilt, the blow-off direction of right side second nozzle 3c and left side second nozzle 3d is respectively towards the middle section of hand hothouse 2, and second nozzle spacing 26 also can be greater than 150mm.

In addition, the sensor 7 for detecting hand 5 is had at the spatial placement of the central authorities of hand hothouse 2 upper surface clipped by second nozzle 3b.Sensor 7 is arranged between the second nozzle 3c and left side second nozzle 3d of right side.

In addition, preferred predetermined distance 24 is more than 50mm below 100mm, does not influence each other to make first jet blowout air-flow 12a and second nozzle blowout air-flow 12b.But, by making the blow-off direction of second nozzle 3b tilt with the blow-off direction of second nozzle 3b relative to the mode of direction of insertion 6 towards inboard 21, same effect can be obtained.Therefore, predetermined distance 24 also can less than 50mm.Wherein, now, in order to make each air-flow not influence each other, preferred predetermined distance 24 is more than 20mm.

Take vertical direction as benchmark, viewed from front during hand hothouse 2, the blow-off direction of preferred first jet blowout air-flow 12a from side, front 20 to the scope of inboard 21 ± 5 ° in.Its reason is as described below.When being tilted beyond 5 ° to side, front 20, the water droplet blown away when the extraction of hand 5 is inserted flies to towards user, and therefore user may be got wet.In addition, when being tilted beyond 5 ° to inboard 21, in order to blow to the blowout air-flow of first jet 3a, need the depths of hand 5 being inserted hothouse 2 in one's hands, ease of use is deteriorated.

Take vertical direction as benchmark, viewed from front during hand hothouse 2, the blow-off direction of preferred second nozzle blowout air-flow 12b goes in the scope of more than 5 ° less than 25 ° from side, front 20 to inboard 21.Its reason is as described below.In order to not make water droplet fly to user, preferably tilt more than 5 ° to inboard 21.In addition, in order to when hand 5 is inserted hothouse 2 in one's hands, hand 5 does not contact with the wall of the inboard 21 of hand hothouse 2, preferably tilts less than 25 ° to inboard 21.

In order to make first jet blowout air-flow 12a and second nozzle blowout air-flow 12b not influence each other, the blow-off direction of first jet 3a and the blow-off direction of second nozzle 3b blow out to the direction be separated from each other.

According to said structure, when extracting hand 5 from hand hothouse 2, second nozzle blowout air-flow 12b tilts to blow over, therefore, it is possible to effectively blow away water droplet in the mode of crossing palm or the back of the hand.

Specifically, when extracting hand 5 from hand hothouse 2, make the back of the hand towards time above, the water droplet being attached to hand 5 is concentrated from the root of thumb to the front end of little finger of toe or the third finger, effectively blows away water droplet.In addition, when extracting hand 5 from hand hothouse 2, make palm towards time above, the water droplet being attached to hand 5 is concentrated from the root of little finger of toe to the front end of thumb or forefinger, effectively blows away water droplet.

In addition, be not blown away and residual water droplet concentrates on the side of hand 5, therefore rub hand 5 dry time water droplet is evaporated effectively, therefore shorten drying time.

In addition, the shape of second nozzle 3b is rectangular slot, but is not limited to this.Such as, second nozzle 3b, by inclined for multiple holes of waveform, clavate, circle, polygon or other shape, also can obtain same effect.
