Fig. 4 is the front elevation of the hand dryer under the state pulling down front panel.Fig. 5 is hand dryer
The enlarged drawing of bottom.Fig. 6 is the drawing in side sectional elevation of operating portion.Fig. 7 is the cross section of operating portion
Magnified partial view.Fig. 8 is the profile of the structure illustrating operating portion.Front panel 11 passes through ABS
(Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene (ABS)) material,
PC (polycarbonate, the Merlon) synthetic resin such as material or its alloy material comes
Molding.As front panel 11 a part operating portion 12 wall ratio operating portion 12 beyond
The wall thickness of front panel 11 thicker, be 2.5～4.0mm degree.Front panel 11 is resin forming
Product, so being also possible to deform, distort.In this case, in order to prevent from operating substrate
15 with operating portion 12 angulation contact, in other words to make operating portion 12 and electrode 14
Contact abreast, preferably make wall thickness thickening.
At the dorsal part (product rear side) of operating portion 12, it is configured with detection electrostatic capacitance change
Electrode 14.Electrode 14 is printed to operate on substrate 15, in the face side in control portion 30
Fixed via retainer 16.Between front panel 11 and electrode 14, between not producing
The mode of gap is configured with dividing plate 17.Dividing plate 17 can also use flexible conducting rubber
Material or there is the other materials of electric conductivity.Its reason is, if at front panel 11 and electricity
Produce space between pole 14, then hands, the accuracy of detection of finger reduce.To there is electric conductivity
The dividing plate 17 that dividing plate 17 is configured between the back side of front panel 11 and electrode 14 can deform, by
This, is when by when remaining certain distance between the back side and the electrode 14 of front panel 11,
Space between the two can be filled.Dividing plate 17 is formed by the material with electric conductivity, so
The feelings that the rear side of electrode 14 front panel 11 become and make detection electrostatic capacitance change is prominent
The state that shape is identical, can regard the back side abutting to front panel 11 just like electrode 14 as.Additionally,
If able to make electrode 14 seamlessly cling to the back side of front panel 11, then can also be set to
Eliminate the structure of dividing plate 17.
It follows that explanation front panel 11 and the fixing means of retainer 16.Fig. 9 is front panel
Back view.Figure 10 is the magnified partial view of the lower backside of front panel.In order at hand dryer 1
Construction, front panel 11 can be pulled down when safeguarding, and be provided with in front panel 11 bottom with
The fixing not shown fitting portion of framework 10.When pulling down front panel 11, make to be positioned at not shown
The screw of fitting portion fluff and pull down afterwards.Not produce between front panel 11 and electrode 14
The mode in gap, at the dorsal part of front panel 11, is arranged in the part relative with retainer 16
Jut 41.And, it is provided with clamping part 42 in retainer 16 side, at front panel 11
When inserting the jut 41 of front panel 11 under the state of Guan Bi, before the clamping of this clamping part 42
The jut 41 of panel 11.
When inserting jut 41, clamping part 42 is flared by jut 41 and is occurred
Elastic deformation such that it is able to the distance of front panel 11 and electrode 14 is remained necessarily.And,
Jut 41 becomes Breadth Maximum in pars intermedia, and the part of root is (that is, with front panel 11
Boundary member) width attenuate compared with pars intermedia.Therefore, inserting to clamping part 42
During jut 41, it is positioned at the state of the root portion of jut 41 in the front end of clamping part 42
Lower stable, front panel 11 becomes by jut 41 and clamping part 42 the most rearwardly side
The state pulled.Thus, between front panel 11 and electrode 14, do not produce space, so
Operation in operating portion 12 is stably detected.And, when constructing, safeguarding, even if wrong
Screw from being forgotten tightening, also will not produce gap, energy between front panel 11 and electrode 14 by mistake
Operation in enough stably detection operating portions 12.And, even without screw, front panel 11
Also framework 10 it is fixedly secured to, so without using screw can improve application property.
Figure 11 is the figure of another structure example illustrating operating portion.Omit about as Fig. 8
The explanation of part.Electrode 14 by the most retractile metal, such as spring or
Leaf spring is constituted.About electrode 14, with the contact portion of front panel 11 and with operation substrate
When the area of the contact portion of 15 is bigger and thickness of slab is thicker, detection sensitivity is more preferable, it is advantageous to this
The electrode 14 of sample.
