However, the above-described hand drying device has a problem that the joint of the surface cover and the portion constituting the hand drying chamber is located on the front side ridge line portion of the housing, and the appearance of the hand drying device is impaired. In addition, when a user inserts a wet hand into the hand drying chamber, water drops that have dropped from the user's hand fall toward the joint between the front cover and the hand drying chamber, so that water enters the inside of the device from this joint. There was a problem that was easy to penetrate.
An object of the present invention is to provide an easy-to-use hand-drying apparatus that has no seam that impairs the appearance of the appearance and has little water intrusion into the apparatus.

Hand drying apparatus of the present invention houses the fan motor, its upper end provided with a housing formed with an opening recess of the upper portion opening to the hand dryer chamber, back of the hand and the palm of the inserted user to the hand drying chamber both sides can be dried by blowing air, the front side of the volar surface of the hand inserted into the hand drying chamber, the hand dryer to be installed toward the surface of the back side of the hand on the wall, before Symbol opening a back side cover which corresponds to the back of the hand side of the housing to form a recess, and the palm-side cover that corresponds to the palm side of the housing defining a front Symbol opening recess is provided in the upper portion of the back side cover, the opening in the recess A first blower nozzle that blows air into the opening, a palm blower nozzle that is provided in the upper portion of the palm cover, and blows air into the opening recess, and first air that is sent out by the fan motor is fed. Airway and number Comprising a gas feed path, and the pre-Symbol first air path, the fan motor side was distracted upward, formed over the upper in a width direction of the housing so as to communicate with the volar blowing nozzles On the other hand, the second air supply path is extended upward from the fan motor side, and the upper part thereof is formed to communicate with the upper side blowing nozzle, and a part of the outer shell of the first air supply path was constituted by the palm-side cover further front side of between the palm-side nozzle to the upper end, KiHiraki opening recess before folded back upper portion of the front cover which forms a front side surface of the housing of the housing A first palm-side inclined surface having a downward slope toward the inward side, while being above the palm-side cover and above the portion constituting the outer shell of the first air supply path Forming a supporting ridge, and forming the first ridge on the supporting ridge It was supported as covered covering the side inclined surface. As a result, the seam between the front cover and the palm side cover not only impairs the appearance because the joint between the front cover and the palm side cover is in the opening recess, but also the seam between the front cover and the palm side cover by adopting a configuration that covers the palm cover. Can provide a hand dryer that can reliably prevent the ingress of water droplets. In addition, the first palm side inclined surface is formed integrally with the surface cover, it is easy to give a moderate roundness to the corner, and it does not hurt even if it hits the user's hand. Since it can be used with its hand placed on the first palm-side inclined surface, the force required for the wheelchair user to lift the arm when the hand is dry is reduced and can be used easily. The surface cover is attached and removed during installation work and when checking the internal functional parts. However, by adopting a structure in which the surface cover is stacked on the palm side cover, the surface cover is not retained by the operator. The operator only needs to fix the surface cover while the handle is suspended from the palm side cover.

Further, the left and right side end portions of the first palm-side inclined surface of the front cover, to form a first folded portion of the back surface integral of said surface cover, the left and right side end portion of the front cover, the palm and it forms the shape of the second folded portion folded back to the side cover side. This makes it possible to prevent water from entering from the joint between the side edges of the front cover and the palm cover.

The gradient angle was gradually increased. As a result, the joints of fingers are generally bent with the palm side inward, so even if the finger is bent slightly with the palm side inward in a natural state, the fingertips are not likely to hit the palm side cover, There is no sense of sanitation, and natural ease of use when inserting a hand is obtained.

  Furthermore, the upper side cover is adjacent to the lower side of the first upper side inclined surface and the first upper side inclined surface inclined downward from the wall side upper end of the housing toward the inside of the opening recess. And a second upper side inclined surface opposed to the second palm side inclined surface substantially parallel to the second upper side inclined surface, and the second upper side inclined surface is disposed on the second upper side inclined surface. The upper side inclined surface was connected to the bottom surface of the opening recess by a curved surface having a substantially arc-shaped cross section. Because of this, the palm side cover bends sequentially as it goes down, while the back side cover side extends almost straight to the bottom of the drying chamber, so the fingertips can be extended even when the fingers are stretched straight. It is hard to hit the instep side cover, does not give the user unsanitary feeling, and provides a natural user-friendliness when inserting a hand.

  According to the present invention, while improving the appearance of the hand drying device, while reliably preventing water intrusion into the device, it provides a natural user-friendliness considering the movement of the user's hand, and is installed. Workability at the time of construction and maintenance can be improved, and even for a wheelchair user, an effect of proposing easy usage can be obtained.

  The main part of the present invention will be described below with reference to FIGS. FIG. 2 is a perspective view of the front cover of the hand dryer according to the embodiment of the present invention as seen from the back side. Moreover, FIG. 3 is a longitudinal cross-sectional view of the hand dryer of this embodiment.

  Since the hand drying device A of the present embodiment is usually installed on a wall along the wall of a building, the back surface of the hand drying device A, that is, the back surface of the case body 14 is flat. Furthermore, in the hand drying apparatus A of the present embodiment, the surface cover 15 is not parallel to the back surface of the case body 14 in order to give a straight and slim appearance. The dimensions are slightly smaller than the top. The front cover 15 is not limited to this shape, and the right and left central portion of the front cover 15 is slightly bulged forward, or the upper and lower central portions of the front cover 15 are bulged to an appropriate degree. You may make it have an external shape.

  As shown in FIG. 2, a palm-side first inclined surface 61 is integrally formed at the upper end portion of the surface cover 15 as a folded shape. A portion constituting the lower end of the palm-side first inclined surface 61 of the surface cover 15 is configured to overlap the supporting convex portion 16 b provided at the upper end portion of the palm-side cover 16. It contacts the palm-side cover 16 at the tip. The size of the supporting ridge 16b with the contact point as the origin is set to be smaller than the distance between the tip of the palm-side first inclined surface 61 and the back surface of the front cover 15. With this configuration, when the surface cover 15 is attached to or detached from the case body 14, the surface cover 15 is rotated around the tip of the palm-side first inclined surface 61. The surface cover 15 can be easily attached to and detached from the case body 14 without the projecting ridge portion 16 b hitting the surface cover 15. When the front cover 15 is fixed to the case body 14, the front cover 15 is in a state of hanging from the palm side cover 16, and the work load for holding the front cover 15 so that it does not fall during the fixing work is unnecessary. The attaching / detaching operation of the front cover 15 is necessary when the hand dryer A is installed or when the functional unit inside the housing 10 is inspected and repaired. However, as described above, these workability can be improved.

  As shown in FIG. 3, the joint S between the front cover 15 and the palm cover 16 is located inside the opening recess 18, so that it cannot be seen from the front side of the hand dryer A, and this joint S is aesthetically pleasing. Will not be damaged. Moreover, since the water which fell to the palm side 1st inclined surface 61 flows into the opening recessed part 18 along a downward slope, the stain | pollution | contamination of the joint S is hard to produce and it can improve the cleanliness of a hand dryer.

  In addition, since the part which comprises the lower end of the palm side 1st inclined surface 61 of the surface cover 15 is made to cover the support convex part 16b of the palm side cover 16, it is the housing 10 from the seam S of these contact parts. It is possible to prevent water from entering the inside.

Corresponding to the side end folded pieces 15a, the supporting convex strips 16b are also provided with convex portions on both side ends, so that water enters the inside of the housing 10 from both side end portions of the palm-side first inclined surface 61. To prevent that. Further, side edge folding pieces 15b serving as projecting second folded portions are formed on both side end portions of the surface cover 15 so as to have an overlap allowance with the case body 14, and both sides of the surface cover 15 are formed. Thus, water can be prevented from entering the housing 10.

Between the left and right side Hasho Kaehen 15a and Gawaen'ori Kaehen 15b, gaps left-side cover 20 and the right side cover 30 are fitted respectively are formed.

  In FIG. 2, an engaging claw 15 c is provided at the lower end of the palm-side front cover 15, and the engaging claw 15 a is engaged with a corresponding portion at the lower part of the case body 14, so that the palm-side front cover 15 is attached. It can be attached to the case body 14. A screw fixing boss may be provided in place of the engaging claw 15c.

  As shown in FIG. 3, on the palm-side cover 16 side of the opening recess 18, the palm-side first inclined surface 61 and the palm-side first inclined surface 61 that are inclined downward toward the inside of the opening recess 18. A palm-side second inclined surface 62 having a larger descending angle than the palm-side second inclined surface 62, and a palm-side third inclined surface 63 having a greater down-gradient angle than the palm-side second inclined surface 62. The cross section is smoothly connected on a substantially circular arc. In the present embodiment, the palm-side third inclined surface 63 is substantially parallel to the vertical direction, that is, the gradient angle is approximately 90 °, but the gradient angle is further increased to increase the palm-side second inclined surface 62 and the palm-side third inclined surface. The continuous contact with the surface 63 may be formed in an overhang shape so as to protrude into the opening recess 18. If comprised in this way, even if the finger inserted in the opening recessed part 18 bends a palm side inward, the distance between a fingertip and the palm side 3rd inclined surface 63 is the palm side 1st inclination from a fingertip. Since the distance from the finger 61 to the lower extension line of the surface 61 and the distance from the fingertip to the lower extension line of the palm-side second inclined surface 62 are far from each other, the fingertip is less likely to contact the palm-side cover 16 and naturally bent fingers Even when inserting, it is possible to eliminate the unsanitary feeling when touching the wall, so that it is not always necessary to stretch out the fingers forcibly and the degree of freedom of use increases.

  Since the palm-side first inclined surface 61 is formed integrally with the surface cover 15, as shown in FIG. 3, the upper-side portion of the surface cover 15, that is, the upper end portion of the palm-side first inclined surface 61 is moderate. Can be rounded. Since each inclined surface on the palm side is also smoothly connected, there is no corner portion that hurts even if the hand hits the inside of the opening recess 18. When a short child or a wheelchair user inserts his / her hand into the opening recess 18, his / her wrist or arm is placed on the portion from the upper end of the surface cover 15 to the palm-side first inclined surface 61. There are no horns that hurt, especially if you are a wheelchair user. it can.

  As shown in FIG. 3, the upper side cover 17 facing the palm side cover 16 and the opening recess 18 has an upper side first inclined surface 64 inclined downward toward the inside of the opening recess 18, An instep-side second inclined surface 65 that is substantially parallel to the palm-side second inclined surface 62 is provided adjacent to the lower end of the instep-side first inclined surface.

  The palm side second inclined surface 62 is provided with a palm side blowing nozzle Na, and the back side second inclined surface 65 is provided with a back side blowing nozzle Nb. In the opening recess 18, a region sandwiched between the palm-side second inclined surface 62 and the back-side second inclined surface 65 is a region where the dry air directly hits the hand. The user's arm extends on the upper extension line of these inclined surfaces, but the palm side second inclined so that the position of the user's shoulder is appropriately separated from the wall where the hand dryer A is installed. By giving the surface 62 and the instep-side second inclined surface 65 an appropriate inclination angle, it is possible to reduce the feeling of pressure with the wall facing you.

  As shown in FIG. 3, the upper second inclined surface 65 is directly connected to the bottom 19 of the opening recess 18 in a substantially arc shape in cross section, but with this configuration, fingers are straightened. Even if the hand is inserted in a state where the fingertip is inserted, it is possible to prevent the fingertip from coming into contact with the instep side cover 17, thereby eliminating the unsanitary feeling during use. It is also a configuration that allows the user to look clearly up to the bottom 19 of the opening recess 18 and has good visibility. When trying to dry the hand, the user can insert the hand with peace of mind, and the interior of the opening recess 18 can be easily cleaned. I can say that.

  More specifically, the palm-side first inclined surface 61 allows the user of the hand dryer A to have a wide entrance to the opening recess 18, thereby eliminating the feeling of pressure for the user. . Moreover, since the palm-side first inclined surface 61 can be tilted more greatly by providing the palm-side second inclined surface 62, the hand insertion port of the opening recess 18 can be shown wider, and the user can press. You can eliminate feelings.

  In FIG. 3, the height of the seam S formed by the palm-side first inclined surface 61 and the palm-side second inclined surface 62 is indicated by an imaginary line T. By disposing the upper end of the second inclined surface 65, it can be seen that the opening recess 18 is formed larger.

  In the upper side cover 17, the part above the imaginary line T may be a horizontal plane, but by providing the upper side first inclined surface 64 as in the present embodiment, the depth of the hand dryer A is increased in appearance. You can feel it small.

It is the schematic showing the disassembly / assembly at the time of installation of the hand dryer which is one Embodiment of this invention. It is a perspective view of the surface cover of the hand dryer which is one Embodiment of this invention.
