(Paragraph No. 0031 in the detailed description of the invention of Patent Document 1) is (a) preventing or reducing unpleasant blows on the face, and (b) blowing off water adhering to the hands by blowing. (E.g., to achieve (a), it is necessary to reduce the amount of air blow, but in this way (b) cannot be achieved sufficiently, conversely, (b) In order to achieve sufficient, it is necessary to increase the amount of air blow, but in this case (a) cannot be achieved sufficiently)), which is a problem in a hand dryer that blows away and removes water adhering to the hand by air blow.

Therefore, in the present invention, (a) preventing or reducing the air blowing from hitting the face and making it uncomfortable, and (b) removing the water attached to the hand by blowing off the air sufficiently by the air blowing. An object is to provide an apparatus.

The hand dryer of the present invention (hereinafter referred to as “the present apparatus”)
An injection port for injecting gas, the injection direction being downward ,
A receiving surface, which is a surface where an injection line extending in the direction of gas injection from the injection port intersects,
This receiving surface is surrounded by the weirs provided on the left and right edges, the plate-like portion of the main body, and the front wall, as seen from the user side of the front of the hand dryer.
An insertion space, which is a space in which a hand can be inserted, is provided between the ejection port and the receiving surface,
As seen from the user's side in front of the hand dryer, a slope that tilts downstream as it approaches the direction of the blowout edge from the insertion space toward the external space in the left-right direction and / or the left or right direction around the ridge line Have a certain discharge slope, or
When viewed from the user side in front of the hand dryer , the discharge slope ridge line and / or the slope of the discharge slope, which slopes to the downstream side as it approaches the direction of the blowout edge from the insertion space in the left-right direction around the ridge line toward the external space, and / or Alternatively, the line corresponding to the ridge line of the discharge slope of only one side, which is a slope inclined to the downstream side as it approaches the direction of the blowout edge from the insertion space of the left side or the right side toward the outer space , is provided to the user. It has a discharge slope that is a slope that slopes downstream as it approaches the direction of the blowout edge, with the near side being high and the side far from the user being low,
It has water removal means for draining and removing water collected between the discharge slope and the weir part formed upward on the discharge edge side of the downstream part of the discharge slope from the through hole to the lower water storage part ,
The remaining part of the discharge slope remains at a position higher than the height of the weir formed upward on the outlet edge side of the downstream part of the discharge slope,
It is a hand drying device that blows off and removes water adhering to the hand.

The present apparatus includes an injection port for injecting gas, a receiving surface, and an insertion space.
The ejection port is a port that ejects gas (for example, air) for blowing off and removing water (liquid) attached to the hand inserted into the insertion space.
The receiving surface is a surface where the injection lines (virtual half straight lines) intersect. The injection line is a virtual half line with the injection port as an end point, and is a half line extending in the gas injection direction from the injection port.
The insertion space is located between the injection port and the receiving surface, and is a space in which a hand to be dried by this device can be inserted (of course, an external space in which a hand can be inserted into the insertion space from an external space and an insertion An opening that communicates with the space is provided.)
For this reason, the gas injected from the injection port flows through the insertion space and collides with the receiving surface (when not blocked by the hand inserted into the insertion space).
And in this apparatus, in the cross section of the receiving surface by the injection plane which is one of the planes including the injection line, the discharge slope which is the slope inclined toward the downstream side as it approaches the direction of the blowout edge from the insertion space toward the external space Have The blowing edge is a part of the edge of the receiving surface, and is an edge portion of the receiving surface located where gas is blown out from the insertion space toward the external space. In addition, the downstream side means the direction opposite to the injection port in both directions along the injection line, and the upstream side means the direction of the injection port (direction opposite to the downstream side) in both directions along the injection line. Say.
This device has a discharge slope which is a slope inclined to the downstream side as it approaches the direction of the blow-off edge from such an insertion space toward the external space, while leaving a part of the discharge slope and the other parts blowing out more than that. It exists on the upstream side of any part of the receiving surface close to the edge, and such a part is left and the other part is closer to the blowing edge than that (the other part leaving the part of the discharge slope) The gas that collides with the receiving surface can be smoothly guided to the blowing edge by the discharge slope by the discharge slope that exists upstream from any part of the receiving surface, so that the gas blows in the direction other than the blowing edge Can be reduced. As a result, (b) the amount of air blown toward the face that exists in a direction other than the blowout edge is reduced even if (b) the amount of blown air that can sufficiently remove the water attached to the hand is removed. , It is possible to prevent or reduce the unpleasantness of the airflow hitting the face.
Here, the degree to which a part of the discharge slope is left and the other part is located on the upstream side of any part of the receiving surface closer to the blowout edge than the other part is left as the part of the discharge slope. The one that is located at the most upstream of the foot of the vertical line down to the injection line (referred to as the most upstream foot of the discharge slope), and the part of the discharge slope is left down from the receiving surface that is closer to the blowout edge than the other part. The distance between the most upstream foot of the vertical line (referred to as the most upstream foot on the blowout edge side) and the distance between the topmost foot on the discharge slope side (of course, the upstream flow foot on the discharge edge side) If it is too small, the above-mentioned effect (the gas colliding with the receiving surface is smoothly guided to the blowing edge by the discharging slope and blows off) is too small. If it is too small and too large, Since problems arise, but only to be a range to balance these,
Usually, preferably 3 cm or more, more preferably 4 cm or more,
Most preferably 5 cm or more,
Conversely, preferably 40 cm or less, more preferably 20 cm or less,
Most preferably, it is 15 cm or less.

In this device, the cross-sectional shape of the receiving surface by any plane that is parallel to the injection plane and within a predetermined distance from the injection plane may be substantially the same as the cross-sectional shape of the receiving surface by the injection plane.
In this way, the receiving surface has substantially the same cross-sectional shape as that of the receiving surface by the injection plane at any position in the direction perpendicular to the injection plane within a predetermined distance from the injection plane (receiving) Substantially the same cross-sectional shape of the surface is formed with a certain width parallel to the injection plane), the flow path width where the gas colliding with the receiving surface flows toward the blowing edge can be ensured and the receiving surface is the injection Since it reduces the unevenness in a part of the direction perpendicular to the plane, the gas can smoothly flow in the blowing edge direction along the receiving surface, reducing the gas blown in the direction other than the blowing edge, It is possible to successfully prevent or reduce uncomfortable hitting on the face (existing in a direction other than the blowing edge).
If the predetermined distance is too small, the above-mentioned effect (gas smoothly flows in the direction of the blow-off edge along the receiving surface) will be small. If it is too large, the device will be large and there will be a problem in installation and handling. Therefore, it is preferable that the range is compatible, and usually, it is preferably 5 cm or more, more preferably 7.5 cm or more, most preferably 10 cm or more, and conversely, preferably 17.5 cm or less, More preferably, it is 15 cm or less, and most preferably 12.5 cm or less.

In this apparatus, in the cross section of the receiving surface by the injection plane, a discharge slope is formed on one side of the receiving surface divided by the injection line, and the downstream side becomes closer to the injection line on the other side of the receiving surface. Inclination, any part may be formed with a guide slope which is a slope existing upstream from the most upstream part of the discharge slope.
By doing so, a guide slope is formed on the other side of the receiving surface divided by the injection line in the cross section of the receiving surface by the injection plane. The guide slope is inclined to the downstream side as it approaches the injection line, and since all of the slopes are on the upstream side of the most upstream part of the discharge slope, when the gas injected from the injection port collides with the receiving surface, It is possible to prevent or reduce the flow of gas to the other side (the side where the guide slope is formed) and to guide the gas well to the one side (the side where the discharge slope is formed). For this reason, the gas can be smoothly guided to the blowing edge along the discharge slope and blown out, and the gas blown out in the direction other than the blowing edge can be reduced, so that the blown air is present in the face (in the direction other than the blowing edge). It is possible to prevent or reduce uncomfortable hits.

In this apparatus, in the cross section of the receiving surface by the injection plane, a pair of discharge slopes and outlet edges may be formed on both sides of the receiving surface divided by the injection line on one side and the other side. .
In this way, in the cross section of the receiving surface by the injection plane, a pair of discharge slopes and blowing edges are formed on both sides of the receiving surface divided by the injection line, so that they collide with the receiving surface. The gas is distributed on both sides of the one side and the other side. The gas distributed to the one side flows along the discharge slope constituting the pair on the one side and blows out from the blowing edge constituting the pair on the one side, and the gas distributed to the other side is on the other side The gas colliding with the receiving surface is smoothly blown out from both sides of the one side and the other side because it can flow along the discharge slope constituting the pair and blow out from the blow-off edge constituting the pair on the other side. be able to. As a result, the gas blown out in the direction other than the blowout edge can be reduced, so that it is possible to successfully prevent or reduce the unpleasantness of the blown air hitting the face (existing in the direction other than the blowout edge).

In this device, the edge of the receiving surface is made up of weirs provided on the left and right edges when viewed from the user side on the front side of the hand dryer, the front wall on the user side, and the plate-like portion of the main body. There is a discharge slope that is surrounded by the wall and that slopes in the left and right direction around the ridge line and / or the left or right direction and slopes downstream as it approaches the direction of the blowing edge from the insertion space toward the external space. It is.
In this way, the wall surface is formed substantially parallel to the injection plane so as to rise toward the upstream side along the edge of the receiving surface, so that the gas flows in the direction of the discharge edge along the injection plane and blows out. Since the gas can be smoothly guided to the edge and blown out, and the gas blown out in the direction other than the blowing edge (particularly the direction in which the wall surface is formed) can be reduced, the blown air is present on the face (in the direction other than the blowing edge). It is possible to prevent or reduce uncomfortable hits.

In this apparatus, the injection direction is directed downward (hereinafter referred to as “the injection direction downward main apparatus”).
Thus, when the gas injection direction is directed downward (of course, the receiving surface is directed upward), when water adhering to the hand inserted into the insertion space is blown away by the injection gas (lower injection direction) Water is mainly blown away in a direction close to the direction), and the blown-off water moves well downward, making it less likely to adhere to the face that is normally higher than the hand position, so that water adheres to the face This can prevent or reduce uncomfortable feelings and unsanitary conditions. In addition, since the apparatus can be easily configured so that the blown water mainly collides with the receiving surface, it is possible to collect water by attaching the collided water droplet to the receiving surface. (It is possible to prevent or reduce water from being scattered around the device (external space) and so on.)
Note that the direction of injection is downward means that the velocity vector of gas injection from the injection port has a vertically downward component, and the injection direction does not necessarily need to be vertically downward, Since the direction closer to the vertical downward direction is more likely to produce the above-described effect, the angle formed by the injection direction with respect to the vertical downward direction (referred to as an inferior angle) is preferably 30 degrees or less, more preferably 20 degrees. Degrees or less, and most preferably 10 degrees or less (of course, the lower limit of the angle is 0 degree where the injection direction coincides with the vertically downward direction).

In the case of this device facing downward in the injection direction, in the cross section of the receiving surface by the injection plane, the receiving surface has a weir part formed so as to rise upstream from the most downstream part of the discharge slope toward the discharge edge side, and discharge It has water removal means for draining and removing water collected between the slope and the weir part from the through hole to the lower water storage part .
Downward in the jetting direction In this device, many of the water droplets blown off from the hand collide with and adhere to the receiving surface, and then move the discharge slope toward the downstream side. The water that has reached the downstream end of the discharge slope may be entrained from the blowout edge to the external space due to gas flow, etc., which causes water to scatter or leak around the device (external space). It may cause contamination of the surrounding area. In order to prevent or reduce this, if the receiving surface has a weir part formed so as to rise toward the upstream side from the most downstream part of the discharge slope, the discharge slope is directed downstream. The water that has moved in this way cannot get over the dam portion formed so as to rise toward the upstream side, and can prevent or reduce scattering or leakage from the blowing edge to the external space.

In the present apparatus, a slope member whose surface forms a discharge slope may be detachably attached.
In this way, the device can be easily configured by attaching a slope member whose surface forms a discharge slope to a conventional hand dryer, so the device according to the installation location, purpose, etc. of the hand dryer It is convenient to select whether or not.

Specifically, FIG. 1 (a) is a front view of the first book apparatus 11. FIG. 1B is a right side view of the first book apparatus 11 (shown from the direction of arrow C in FIG. 1A). FIG. 2 is a cross-sectional view of the first main apparatus 11, and more specifically, FIG. 2 (a) is a cross-sectional view taken along the line AA of FIG. 1 (a), and FIG. It is BB sectional drawing of). The first book apparatus 11 is demonstrated with reference to FIG.1 and FIG.2. Here, the vertically upward direction is indicated by an arrow E1, and the vertically downward direction is indicated by an arrow E2.

And a second portion 21b (intermediate portion) that connects the first portion 21a and the third portion 21c.

A power cord (not shown) for supplying power for driving a blower (not shown) accommodated in the first portion 21a is attached to the first portion 21a, and one end of the power cord (not shown) is attached to the first portion 21a. By being connected to a commercial power source, power is supplied to a blower (not shown) connected to the other end of a power cord (not shown). A sensor (not shown) for detecting that a hand (not shown) is inserted into the injection space 19 is attached to the main body 21 (the direction in which the hand (not shown) is inserted into the injection space 19 is indicated by an arrow S. The blower (not shown) is operated only when the sensor (not shown) detects that a hand (not shown) is inserted into the injection space 19.
When the blower (not shown) is operated, the air existing around the first main unit 11 is sucked by the blower (not shown), pressurized and pumped to the nozzle 13, so that the air from the nozzle 13 is moved in the direction of arrow D ( Here, it is injected vertically downward).

The air injected from the nozzle 13 in the direction of arrow D (vertically downward) flows through the injection space 19 and collides with the receiving surface 15 of the third portion 21c (a hand (not shown) is inserted into the injection space 19). If so, the jet air flows over the surface of the hand, and the water adhering to the surface of the hand is blown off and removed.) The receiving surface 15 has a similar shape on both sides with a ridge line 15c (substantially along a line segment perpendicular to the arrow D) extending in a direction perpendicular to the arrow D (here, substantially horizontal). (In detail, the receiving surface 15 is substantially plane-symmetric with respect to a plane (vertical plane) including the ridge line 15c and including the arrow D), and one side surface 15a on one side of the ridge line 15c, The other side surface 15b is formed on the other side with the ridge line 15c as a boundary.

3 is a cross-sectional view taken along the line FF in FIG. 1B (the cross-sectional structure of the third portion 21c is different from that in FIG. 2B), and will be described with reference to FIG. In addition, the FF cross section is based on the injection plane which is one plane including the injection line 16 which is a half straight line having the end opening 16n of the nozzle 13 extending in the injection direction (arrow D direction) of the gas from the nozzle 13 as an end point 16a. It is a cross section. The end point 16a is the center of gravity of the tip opening 13n of the nozzle 13. The jet line 16 intersects with the ridge line 15c, and one side surface 15a and the other side surface 15b are formed on both sides with the ridge line 15c as a boundary. The direction of the tip opening 13n (jet port) of the nozzle 13 along the injection line 16 is the upstream direction (the direction of arrow G1 in FIG. 3), and the tip opening 13n (jet port) of the nozzle 13 along the jet line 16 Is the downstream direction (the direction of arrow G2 in FIG. 3) (that is, the upward direction in FIG. 3 is upstream and the downward direction in FIG. 3 is downstream).

The air jetted in the direction of arrow D along the jet line 16 from the tip opening 13n (jet port) of the nozzle 13 collides in the vicinity of the ridge line 15c, and both sides (one side 15a side and the other side 15b side) of the ridge line 15c. ) Is distributed almost evenly. On the other hand, the air that has flowed into the side surface 15a passes through the weir surface 15a3 from the inclined surface 15a1 through the bottom surface 15a2, and then blows out from the injection space 19 to the external space 99. Similarly, the air that flows into the other side surface 15b passes through the weir surface 15b3 from the inclined surface 15b1 through the bottom surface 15b2, and then blows out from the injection space 19 to the external space 99.

(Second Embodiment)
FIG. 4 is a view showing a hand drying device (hereinafter referred to as “second device”) 61 according to the second embodiment of the present invention. Specifically, FIG. 4 (a) is a front view of the second device 61. FIG. 4B is a right side view of the second book apparatus 61 (shown from the direction of arrow C in FIG. 4A). 5 is a cross-sectional view of the second book apparatus 61. Specifically, FIG. 5 (a) is a cross-sectional view taken along line AA of FIG. 4 (a), and FIG. 5 (b) is a cross-sectional view of FIG. It is BB sectional drawing of). The second book apparatus 61 will be described with reference to FIGS. 4 and 5. Here, the vertically upward direction is indicated by an arrow E1, and the vertically downward direction is indicated by an arrow E2.
As in the case of the first book apparatus 11, the second book apparatus 61 is roughly a main body part 21 and a nozzle 13 attached to the main body part 21 (the air blowing direction is indicated by an arrow D. Here, the arrow D is used. The arrow D is a vertically downward direction.), A blower (not shown) attached to the main body 21 for sucking air that is present around the second main device 61, increasing the pressure, and blowing the air to the nozzle 13, and the main body 21 The water storage part 17 arrange | positioned below this.
The second book apparatus 61 is different from the first book apparatus 11 only in the receiving surface 65 as will be described later, and has the same configuration as the first book apparatus 11 other than that. For this reason, the same elements as those in the first book apparatus 11 in the second book apparatus 61 are denoted by the same reference numerals as those in the first book apparatus 11, and the description overlapping the description of the first book apparatus 11 is omitted. (Refer to the description of the first apparatus 11 if necessary).

Also in the second main unit 61, the air jetted in the direction of arrow D (vertically downward) from the nozzle 13 flows through the jet space 19 and collides with the receiving surface 65 of the third portion 21c (in the jet space 19). If a hand (not shown) is inserted, the jet air flows on the surface of the hand, and the water adhering to the surface of the hand is blown off and removed. The receiving surface 65 continues to a slope 65b (substantially rectangular shape) along a plane (a plane inclined with respect to the horizontal plane) that forms a predetermined angle with respect to the arrow D direction, and a lowermost part (downstream side) of the slope 65b. A bottom surface 65c (substantially rectangular shape) along a plane (substantially horizontal plane) substantially perpendicular to the arrow D direction, and a weir surface 65a (substantially rectangular shape) formed so as to rise from the uppermost portion (most upstream side) of the slope 65b. And a weir surface 65d (substantially rectangular shape) formed so as to rise from the bottom surface 65c (formed on the edge of the bottom surface 65c opposite to the slope 65b). .

6 is a cross-sectional view taken along line FF in FIG. 4B (the cross-sectional structure of the third portion 21c is different from that in FIG. 5B), and will be described with reference to FIG. In addition, the FF cross section is a cross section by the injection plane which is one plane including the injection line 16 which makes the front-end | tip opening 13n of the nozzle 13 extended in the injection direction (arrow D direction) of the gas from the nozzle 13 the end point 16a. The end point 16a is the center of gravity of the tip opening 13n of the nozzle 13. The jet line 16 intersects (passes) the slope 65b, and the slope 65b (substantially rectangular) is formed substantially perpendicular to the FF plane. In the FF cross section, the slope 65b is formed by the injection line 16 on one side (right side of the injection line 16 in FIG. 6) and the other side existing on the other side (left side of the injection line 16 in FIG. 6). It is divided into a side portion 65b2. The direction of the tip opening 13n (jet port) of the nozzle 13 along the jet line 16 is the upstream direction (the direction of arrow G1 in FIG. 6), and the tip opening 13n (jet port) of the nozzle 13 along the jet line 16 Is the downstream direction (the direction of arrow G2 in FIG. 6) (that is, the upward direction in FIG. 6 is upstream and the downward direction in FIG. 6 is downstream).
The slope 65b formed by the one side portion 65b1 and the other side portion 65b2 has a rectangular shape (plane) as a whole, and is at a predetermined angle (angle d in FIG. 6, where d = about 70) with the jet line 16. Degrees, about 20 degrees to the horizontal plane). The bottom surface 65c is a substantially rectangular shape substantially perpendicular to the jet line 16 having a substantially rectangular shape with one side existing on the most downstream side of the four sides of the slope 65b (substantially horizontal side of the one side portion 65b1) as one side. I am doing. The weir surface 65d is formed at a position rising from the jet line 16 at a position farther from the bottom surface 65c. The dam surface 65a is formed at a position rising adjacent to one side (substantially horizontal side of the other side portion 65b2) existing on the most upstream side of the four sides of the slope 65b.

The air jetted in the direction of arrow D along the jet line 16 from the tip opening 13n (jet port) of the nozzle 13 collides with the slope 65b (near the boundary between the one side portion 65b1 and the other side portion 65b2) and is jetted. The slope 65b is inclined with respect to the air velocity direction (arrow D direction) (not perpendicular to the air velocity direction (arrow D direction), but about 20 degrees with respect to this perpendicular). Therefore, most of the air flows on the slope 65b in the direction of the bottom surface 65c (the air colliding with the slope 65b flows not in the direction of the other side portion 65b2 but mostly in the one side portion 65b1 toward the downstream side). Then, the air that flows in the direction of the bottom surface 65c along the one side portion 65b1 passes through the weir surface 65d through the bottom surface 65c and blows out from the injection space 19 to the external space 99. Part of the air flows through the other side portion 65b2 in the direction of the weir surface 65a, passes through the weir surface 65a, and blows out from the injection space 19 to the external space 99, but most of the air passes through the bottom surface 65c due to the inclination of the inclined surface 65b. It passes through the surface 65d and blows out from the injection space 19 to the external space 99.
Thus, the receiving surface 65 is directed from the injection space 19 to the external space 99 in the cross section (for example, FIG. 6) of the receiving surface by the injection plane (for example, the FF surface) which is any plane including the injection line 16. The slope is inclined to the downstream side (in the direction of arrow G2 in FIG. 6) as it approaches the direction of the blowout edge (here, the edge 65df on the external space 99 side of the weir surface 65d) constituting a part of the edge of the receiving surface 65. While having a certain one side portion 65b1 (discharge slope), a portion 65b1a of the one side portion 65b1 (here, a portion located upstream of the weir surface 65d (the arrow G1 direction side in FIG. 6)) It exists on the upstream side (in the direction of arrow G1 in FIG. 6) of any part of the receiving surface 65 that is closer to the blowing edge 65df than the portion 65b1a).
In addition, the other side (the left side of the injection line 16 in FIG. 6) of the receiving surface 65 divided by the injection line 16 is inclined toward the downstream side (arrow G2 direction side in FIG. 6) as it approaches the injection line 16. The other side portion 65b2 (guidance in the direction of arrow G1 in FIG. 6) is also upstream of the most upstream portion (here, the portion through which the injection line 16 passes) of the one side portion 65b1 (discharge slope). Slope).

A front wall 23 (flat plate) is formed substantially parallel to the FF plane so as to rise toward the upstream side (in the direction of arrow G1 in FIG. 6) along at least a part of the edge of the receiving surface 65. Yes.
The second portion 21b includes a flat plate-like portion 21ba that is substantially parallel to the FF plane (also substantially parallel to the front wall 23) and both sides of the plate-like portion 21ba (continuous from the weir surface 65a and the weir surface 65d). And a ridge portion 21bb formed in a direction parallel to the jet line 16.
A receiving surface 65 is formed between the second portion 21b and the front wall 23 (refer to FIG. 5A in particular), and the width of the receiving surface 65 (dimension in the direction perpendicular to the FF surface) is The portion formed between the plate-like portion 21ba and the front wall 23 (the slope 65b and the bottom surface 65c) is the same (with a width k1), and is between the ridge portion 21bb and the front wall 23. The portions (the weir surface 65a and the weir surface 65d) formed in the same shape are the same (the width is k2, k2 <k1).

A through hole 75 is formed in the bottom surface 65 c substantially parallel to the jet line 16.
Under the third portion 21c, a water reservoir 17 having a bottomed and uncovered dish shape is detachably attached, and water collected on the bottom surface 65c flows into the water reservoir 17 via the through hole 75. And stored. The water stored in the water storage unit 17 may be discarded by removing the water storage unit 17 or may be drained by connecting a drain pipe (not shown) to the water storage unit 17.

As described above, the second main apparatus 61 is configured to eject the gas (here, air) and the gas (here, the tip opening 13n of the nozzle 13) and the gas (from the nozzle 13 (tip opening 13n)). An injection line that is a half straight line with the injection port (tip opening 13n of the nozzle 13) extending in the injection direction (direction of arrow D) of air) as an end point 16a (here, the center of gravity of the injection port (tip opening 13n of the nozzle 13)). A receiving surface 65 that intersects 16, and an insertion space (here, an injection space 19) that is a space in which a hand can be inserted between the injection port (tip opening 13 n of the nozzle 13) and the receiving surface 65. The cross section of the receiving surface 65 (for example, FIG. 6) by an injection plane which is any plane including the injection line 16 (the FF plane of the cross section shown in FIG. 6 is one of the injection planes). 6), the insertion space (jet) The direction opposite to the injection port of the injection line 16 (the tip opening 13n of the nozzle 13) as it approaches the direction of the blowout edge (edge 65df) that forms part of the edge of the receiving surface 65 from the space 19) toward the external space 99 It has a discharge slope (one side portion 65b1) that is a slope inclined to the downstream side (in the direction of arrow D2 in FIG. 6) (at the arrow D2 direction) and at least a part of the discharge slope (one side portion 65b1) (here Then, at least a part 65b1a of the one-side part 65b1) has an injection port (the tip opening 13n of the nozzle 13) of the injection line 16 than any part of the receiving surface 65 closer to the blowing edge (edge 65df) than that (part 65b1a). ) (The direction opposite to the arrow D) is a hand drying device that exists on the upstream side (the arrow G1 direction side in FIG. 6) and blows away the water adhering to the hand. Here, the gas (air) injected from the injection port (the tip opening 13n of the nozzle 13) collides with the discharge slope (one side portion 65b1), and here the discharge slope (one side portion). 65b1), a discharge slope (one side portion) existing on the upstream side (in the direction of arrow G1 in FIG. 6) of any part of the receiving surface 65 closer to the blowing edge (edge 65df) than that (part 65b1a). 65b1) collides with at least a part (part 65b1a).

In the second main apparatus 61, the ejection plane (for example, the FF plane illustrated in FIG. 6) is parallel to the ejection plane (for example, the FF plane illustrated in FIG. 6) and a predetermined distance. The cross-sectional shape of the receiving surface 65 by any plane (here, any plane parallel to the ejection plane passing through the weir surface 65a and the weir surface 65d) is also shown by the ejection plane (FIG. 6). The cross-sectional shape of the receiving surface 65 by the (F-F surface) is substantially the same.

A discharge slope (one side portion 65b1) is formed on the right side of the injection line 16 in FIG. 6 and approaches the injection line 16 on the other side of the receiving surface 65 (left side of the injection line 16 in FIG. 6). As shown in FIG. 6, it is inclined to the downstream side (arrow G2 direction side in FIG. 6), and any part is upstream (in FIG. A guide slope (the other side portion 65b2) that is a slope existing on the arrow G1 direction side is formed.

(Third embodiment)
FIG. 7 is a cross-sectional view showing a main body 101 for constructing a hand drying apparatus (hereinafter referred to as “third main apparatus”) according to the third embodiment of the present invention (the same cross section as in FIGS. 3 and 6 described above). Is shown.) The main body 101 will be described with reference to FIG. 7, but the main body 101 is different from the first main apparatus 11 only in that the receiving surface 15 of the first main apparatus 11 is changed to a lower surface 115 as described later. Other than that, it has the same configuration as the first main apparatus 11. For this reason, in the main body 101, the same elements as those in the first main apparatus 11 are denoted by the same reference numerals as those in the first main apparatus 11, and the description overlapping with the description of the first main apparatus 11 is omitted (necessary). (Refer to the description of the first book 11 according to the above).
The main body 101 is roughly a main body portion 21 and a nozzle 13 attached to the main body portion 21 (air blowing direction is indicated by an arrow D. Here, the arrow D is a vertically downward direction). A blower (not shown) attached to the main body portion 21 for sucking air that is present around the main body 101, increasing the pressure, and blowing the air to the nozzle 13; and a water storage portion 17 disposed below the main body portion 21. Become.

The air jetted in the direction of arrow D (vertically downward) from the nozzle 13 flows downward in the jet space 19, but collides with a slope member (described later) placed and disposed on the lower surface 115. If a hand (not shown) is inserted into 19, the jet air flows on the surface of the hand, and the water adhering to the surface of the hand is blown off and removed.
The lower surface 115 is formed so that a portion through which the injection line 16 passes becomes the top, and a central portion 115b having a gentle mountain shape that gently descends from the top to both sides of the injection line 16, and rises on both sides of the central portion 115b. Dam surfaces 115a and 115c. When moisture exists on the central portion 115b, the moisture naturally moves to both sides of the central portion 115b (in the direction of the base of the mountain shape formed by the central portion 115b) due to the mountain shape of the central portion 115b.
Although not shown in FIG. 7, the injection line 16 is located near the dam surfaces 115 a and 115 c of the central portion 115 b (the position of the mountain-shaped foot formed by the central portion 115 b), as in the first main apparatus 11. Through holes 25a and 25b (not shown in FIG. 7, refer to FIGS. 1 and 2) are drilled substantially parallel to each other, and the water collected therein passes through holes 25a and 25b (FIG. 7). (Not shown) flows into the water storage part 17 through the storage (not shown).

FIG. 8A is a cross-sectional view (a cross-sectional position is the same as FIG. 7) showing the third book apparatus 301 configured by disposing the slope member 305 in the main body 101. The upper surface 307 of the slope member 305 has the same shape and dimensions as those obtained by combining the slope 15a1, the bottom surface 15a2, the slope 15b1, and the bottom surface 15b2 in the first apparatus 11, and the slope member 305 has a central portion. 115b.
Note that the slope member 305 guides moisture dropped on the upper surface 307 to the through holes 25a and 25b (not shown in FIGS. 7 and 8A) of the central portion 115b. Although a water passage hole 305h is formed at a position corresponding to (not shown in FIG. 8 (a)), the present invention is not limited to this, and the inclined member 305 is punched at some places. You may make it comprise with a metal (plate member), or you may comprise with the board member in which the slit which is a long and slender hole is formed in several places.
As described above, the third main unit 301 has the main body 101 with the inclined member 305 having the surface (the upper surface 307) forming the discharge inclined surface (here, the upper surface 307 corresponding to the inclined surface 15a1 and the inclined surface 15b1 in the first main device 11). It can be attached detachably. For the effects of the third main apparatus 301, refer to the description of the first main apparatus 11.

(Fourth embodiment)
FIG. 8B shows the fourth embodiment of the present invention configured by arranging the slope member 405 in the main body 101 (the same as that shown in FIG. 7 used in the third main unit 301). It is sectional drawing (cross-sectional position is the same as that of FIG. 7) which shows the hand-drying apparatus (henceforth "4th apparatus") 401. The upper surface 407 of the slope member 405 has the same shape and size as the portions of the weir surface 65a, the slope 65b, and the bottom surface 65c in the second main unit 61, and the slope member 405 has the central portion 115b and It is placed on the weir surface 115a.
The slope member 405 guides the moisture dropped on the upper surface 407 to the through hole 25a (not shown in FIGS. 7 and 8B) of the central portion 115b, and therefore the through hole 25a (FIGS. 7 and 8B). However, the present invention is not limited to this, and the slope member 405 is formed by punching metal (plate member) with holes drilled in some places. You may make it comprise with the board member in which the slit which is an elongate hole like a slat-like is formed in some places.
As described above, the fourth apparatus 401 is provided with the slope member 405 formed by the surface (upper surface 407) of the discharge inclined surface (here, the portion of the upper surface 407 corresponding to the one side portion 65b1 in the second book apparatus 61). It can be attached freely. For the effects of the fourth book apparatus 401, refer to the description of the second book apparatus 61.

The first book apparatus 11, the second book apparatus 61, the third book apparatus 301, and the fourth book apparatus 401 are compared with the main body 101 as a comparative example (without a slope member). Experiments were carried out to determine whether or not it would be possible to successfully prevent or reduce uncomfortable hitting, and (b) to sufficiently remove the moisture adhering to the hand by blowing away air. The main body 101, the first main apparatus 11, the second main apparatus 61, the third main apparatus 301, and the fourth main apparatus 401 all control the injection amount (volume flow rate) of air from the nozzle 13 (the tip opening 13n of the nozzle 13). The same nozzles 13 are used for the main body 101, the first book apparatus 11, the second book apparatus 61, the third book apparatus 301, and the fourth book apparatus 401. )) An experiment was conducted in which a hand (not shown) was inserted into the ejection space 19 and the water adhering to the surface of the hand was blown off and dried. The insertion direction of the hand is performed from the same direction in the main body 101, the first book apparatus 11, the second book apparatus 61, the third book apparatus 301, and the fourth book apparatus 401. FIG. 1 (b) and FIG. This is indicated by an arrow S in FIGS. 4 (a), 4 (b) and 5 (a).
(B) The effect of blowing and removing the water adhering to the hand by blowing is almost the same for all of the main body 101, the first book apparatus 11, the second book apparatus 61, the third book apparatus 301, and the fourth book apparatus 401. Although it was the same level (the same amount of air flow), (a) the effect of preventing or reducing the unpleasantness of the airflow hitting the face was that the main body 101 felt uncomfortable when the strong wind hit the face. The second book apparatus 61, the third book apparatus 301, and the fourth book apparatus 401 are clearly weaker in wind than the main body 101. The first book apparatus 11, the second book apparatus 61, The third book apparatus 301 and the fourth book apparatus 401 are (a) preventing or reducing the unpleasantness of the blown air hitting the face, and (b) removing the water adhering to the hand by blowing off the blown air sufficiently. And balance well I was sure that.

FIG. 9 is an enlarged end view (showing the QQ cross section in FIG. 1A) showing a modified example of the first book apparatus 11 (hereinafter referred to as “modified first apparatus”). The modified first device will be described with reference to FIG. 9 indicates an end surface formed by a surface including a point Z1 where the injection line 16 and the receiving surface 15 intersect among the planes perpendicular to the injection plane P including the injection line 16.
Compared to the first main apparatus 11, the modified first apparatus is inclined so that a part of the receiving surface 15 (slopes 15a1, 15b1) is lower on the plate-like part 21ba side (downstream direction (arrow G2 direction)). The only difference is that it is different, and the rest is the same. In FIG. 9, the receiving surface 15 (ridge line 15 c) of the first main device 11 is indicated by a one-dot chain line K, but the spray line 16 and the one-dot chain line K (the receiving surface 15 of the first main device 11) intersect. The normal line of the alternate long and short dash line K (the receiving surface 15 of the first book apparatus 11) at the point Z2 substantially coincides with the injection line 16. On the other hand, the normal line V and the injection line 16 at the point Z1 of the receiving surface 15 (ridge line 15c) of the modified first apparatus are the angle Y (which is an inferior angle among the angles formed by the normal line V and the injection line 16). I'm talking to you. Due to the angle Y, the receiving surface 15 of the deformed first device is lower on the plate-like portion 21ba side (downstream direction (arrow G2 direction)) than the front wall 23 side (the side where the user's face of the deformed first device is present). As a result, it has been clarified that the wind blown near the point Z1 can be effectively prevented from blowing out from the front wall 23 side (wind can be prevented from blowing on the face of the user of the modified first device). . The angle Y is in the range of 0 to 90 degrees because it is an inferior angle among the angles formed by the normal line V at the point Z1 of the receiving surface 15 and the injection line 16, but if the angle Y is too small, the front wall is formed by the angle Y. The blowout prevention effect from the 23 side is not sufficiently achieved, and if the angle Y is too large, the device becomes large. Therefore, it is preferable that these ranges be compatible. Usually, as the angle Y, Preferably it is 1 degree or more, more preferably 3 degrees or more, most preferably 5 degrees or more, and conversely, preferably 20 degrees or less, more preferably 15 degrees or less, most preferably 10 degrees or less (preferably 1 -20 degrees, more preferably 3-15 degrees, most preferably 5-10 degrees).
As with the first book apparatus 11, in the second book apparatus 61, part of the receiving surface 65 (slope 65b) is inclined so that the plate-like portion 21ba side is low (downstream direction (arrow G2 direction)). Thus, it is possible to effectively prevent the wind blown near the point Z1 from the front wall 23 side (the preferable range of the angle Y is the same as described above).
In addition, it goes without saying that the receiving surface 15 and the receiving surface 65 that are inclined according to the angle Y in this way may be configured using a slope member.
As described above, in the cross section of the plane including the injection line 16 and perpendicular to the injection plane P, the angle Y formed by the normal line V of the receiving surface and the injection line 16 at the point where the injection line 16 and the receiving surface intersect is 1 to 1. If it is 20 degrees, it extends in the upstream direction (in the direction of arrow G1) from the receiving surface in the cross section on both sides of the normal line (substantially coincides with the injection line 16) when the angle Y is 0 (Y = 0 degrees). The side opposite to the side where the normal line V exists (in FIG. 9, the right side of the normal line when the angle Y is 0 (Y = 0 degree) (substantially coincides with the jet line 16)) (in FIG. 9, the angle When Y is 0 (Y = 0 degree), the blowing of wind toward the normal line (on the left side of the injection line 16) is reduced. As a result, the face of the user of the apparatus is positioned on the opposite side (in FIG. 9, the left side of the normal line (substantially coincides with the jet line 16) when the angle Y is 0 (Y = 0 degree)). This effectively prevents the wind from blowing on the face.
