The long hole 68B and the long hole 69B are formed at positions on the back side of the long hole 61B. The long hole 68 </ b> B and the long hole 69 </ b> B are formed such that the rear side end portion is disposed closer to the center side of the nozzle cover 20 than the front side end portion. Further, the long hole 69B is formed at a position on the back side further than the long hole 68B. The long hole 68B and the long hole 69B are provided in parallel at a predetermined interval.
Here, the long hole 68A, the long hole 69A, the long hole 68B, and the long hole 69B constitute a second nozzle portion.
According to the present embodiment, on the rear side, the amount of blown air is larger than the center of the nozzle cover, so that it is possible to enhance the drying effect due to manual massage after manual insertion.
A sensitivity sensor 22 is provided between the first nozzle portion and the second nozzle portion.
Moreover, it is preferable to provide a 3rd nozzle part in the back of a 1st nozzle part and a 2nd nozzle part. By further providing the third nozzle part, when a wet hand is inserted, airflow hits the entire hand and blows water droplets at the same time. be able to.

Further, as shown in FIGS. 11 and 12, the nozzle portion 60 is provided with a protruding surface 23.
The protruding surface 23 is the lower surface of the nozzle cover 20 and is formed inward from the outer periphery of the nozzle cover 20. The protruding surface 23 includes an inclined surface 23f on the front surface side, an inclined surface 23s on the side surface side, and an inclined surface 23b on the rear surface side, and is connected to the outer peripheral portion of the lower surface of the nozzle cover 20 by these inclined surfaces 23f, 23s, and 23b. Yes.
According to the present embodiment, the outer peripheral side of the nozzle cover 20 is thin and the central portion of the nozzle cover 20 is thick, so that the nozzle cover 20 looks thin at the time of installation, the feeling of pressure by the nozzle cover 20 is reduced, and the drying chamber Can be felt widely. In addition, since the center portion of the nozzle cover 20 is formed thick, an air passage space reaching the nozzle portion 60 can be secured, so that the long hole 61A, the long hole 61B, the long hole 68A, the long hole 69A, the long hole 68B, and the long A uniform blown air volume from the hole 69B can be ensured. Furthermore, it is easy to form an air flow from the outer peripheral portion to the nozzle portion 60 on the front surface and the side surface of the protruding surface 23, while an air flow from the drying chamber to the nozzle portion 60 is easily formed on the rear surface of the protruding surface 23.
Moreover, as shown in FIG. 12, the nozzle part 60 differs in the protrusion length from the protrusion surface 23. As shown in FIG.

In this way, the protruding length of the second nozzle portion is made larger than the protruding length of the first nozzle portion, and the protruding length of the long hole 69 is set to be longer than the long hole 68 in the second nozzle portion. By increasing the distance, the reach distance of the blown air on the rear side can be increased. For example, when the projecting length of the long hole 61 is 1, the projecting length of the long hole 68 is doubled and the projecting length of the long hole 69 is tripled, thereby increasing the wind pressure effect on the rear surface side. be able to.

  As shown in FIGS. 12 and 13, the long hole 68 and the long hole 69 have a blowing direction in the vertical direction, but the long hole 61 has a blowing direction inclined about 10 degrees from the vertical direction to the rear side. As in this embodiment, the air blown from the long hole 68 and the long hole 69 into the drying chamber is inclined to the air from the long hole 61 by tilting the blowing direction of the long hole 61 located on the forefront side toward the rear side. Ascending flow can induce a flow rising from the rear side of the drying chamber, can promote a steady outflow of air from the drying chamber, and can prevent noise caused by irregular outflow of air . Moreover, the flow of the air which circulates from the inclined surface 23b of the protrusion surface 23 to the nozzle part 60 can be generated by setting it as the flow of the air rising from the rear surface side of the drying chamber. Therefore, especially when warm air is used, the feeling of warm air can be enhanced by the circulation of air, and the drying effect can be enhanced.

Further, as shown in FIG. 13, a current plate 24 such as a wire mesh or punching metal is provided on the suction side of the nozzle portion 60. The rectifying plate 24 can reduce turbulence, increase the reach distance of blown air from the nozzle portion 60, and reduce noise.

As shown in FIG. 15, the LED base 26 and the display cover 27 are fixed to the duct cover 25. The LED base 26 and the display cover 27 are provided to face each other with a predetermined interval.
As shown in FIG. 16, a plurality of LEDs 26 </ b> A are arranged on the surface of the LED base 26 that faces the display cover 27. Moreover, the light of each LED26A is divided by providing the shielding board 26B between each LED26A.
As shown in FIG. 17, the display cover 27 forms a prism, and the surface of the prism on the side of the LED base 26 is diamond cut 27A to scatter incident light, thereby enhancing the surface emission effect. ing.
On the upper surface side of the duct cover 25, lattice-shaped reinforcing ribs 25A are formed. A plurality of joints 25 </ b> B are formed on the outer periphery of the duct cover 25, and a joint 25 </ b> C is formed at the center of the duct cover 25.

  As shown in FIG. 18, a ventilation path 150A is formed on the upper surface side of the lower surface side nozzle cover 20B. This ventilation path 150A is constituted by a double-structured wall surface 150B provided on the outer peripheral portion of the lower surface side nozzle cover 20B. A wall surface 150B located on the front surface side of the lower surface side nozzle cover 20B extends to the center of the lower surface side nozzle cover 20B to form an extending portion 150C. The extending portion 150C is formed between the long hole 61A and the long hole 61B, and between the long hole 69A and the long hole 69B. Further, a sensitivity sensor opening 22A is formed in a space separated from the ventilation path 150C by the extension 150C. A plurality of joint portions 20C corresponding to the joint portions 25B of the duct cover 25 are provided on the outer peripheral portion of the wall surface 150B. Further, a joint portion 20D corresponding to the joint portion 25C of the duct cover 25 is provided in a space separated from the ventilation path 150C by the extending portion 150C. The duct cover 25 is fixed to the lower surface side nozzle cover 20B by these joint portions 25B, 25C, 20C, and 20D. Here, the reason why the sensitivity sensor 22 is located in the middle is that when a person first inserts his / her hand into the drying chamber 10, there is a habit of bringing the hand into the middle, and when the hand dries, it is confirmed. This is because there are many cases of hand scrubbing in the middle. Further, when high pressure air enters the nozzle cover portion 20, the joint portion between the upper surface side nozzle cover 20A and the lower surface side nozzle cover 20B is opened by pressure, and the central joint portion 20D is screwed so that air does not leak. To maintain the bonding strength.

  As in this embodiment, the LED cover 26 is arranged on the front end portion of the nozzle cover 20 and the indicator cover 21 on the upper surface of the nozzle cover 20 is made to emit light by using the display cover 27 that forms a prism, so that the nozzle cover 20 is made thin. In addition, the distance between the LED 26A and the indicator 21 can be sufficiently secured. In other words, compared with the case where the substrate, the LED, and the prism are stacked on the lower surface side nozzle cover 20B, the LED light direction is arranged by arranging the substrate with LED horizontally and arranging the prism at 45 degrees on the side. This is because the substrate, the LED, and the prism spread in the horizontal direction in order to cause the indicator 21 to emit light from the horizontal to the vertical direction, but the vertical direction can be reduced.

As shown in FIG. 23, the hand dryer of this embodiment includes a fan motor unit 50 having a fan motor 51, a filter unit 80 disposed on the upstream side of the fan motor unit 50, and the fan motor unit 50 and the filter. The fan motor unit 50 and the filter unit 80 are provided in the main body case 40 by fixing the unit 80 to the back side main body case 40B. The front sides of the fan motor unit 50 and the filter unit 80 are covered with a front body case. A drain tank 30 is provided at the lower part of the front side main body case. The filter unit 80 is disposed above the drain tank 30. The dust collection filter 81 included in the filter unit 80 is housed in a filter case 81A, and the filter case 81A is provided so as to be removable from the drain tank 30 side. The filter case 81A is coupled to the filter unit 80 by a decorative screw 81B as shown in FIG. A pre-filter 32 that collects dust larger than the dust collection filter 81 is disposed between the drain tank 30 and the filter unit 80. A main body case suction port 101 is provided on the lower surface of the main body case 40. The filter unit 80 has a dust collection filter 81, and a filter unit suction port 82 is formed on the upstream side of the dust collection filter 81, and a filter unit outlet 83 is formed on the downstream side of the dust collection filter 81. is doing. The fan motor unit 50 has a fan motor 51 and forms a fan motor unit suction port 52. Here, the fan motor 51 rotates counterclockwise (arrow A in the figure) with the direction perpendicular to the back side main body case 40B as a rotation axis. In the present embodiment, the filter unit outlet 83 and the fan motor unit inlet 52 are directly connected.

The ventilation path from the main body case suction port 101 to the fan motor unit suction port 52 will be described below with reference to FIGS.
The air sucked from the main body case suction port 101 flows upward (the positive direction of the Y axis) along the ventilation path 111, and flows laterally (the negative direction of the X axis) along the ventilation path 112. The air flows again upward (in the positive direction of the Y axis) along the path 113, and flows laterally (in the positive direction of the X axis) along the ventilation path 114, thereby reaching the filter unit suction port 82. Note that these ventilation paths 111 to 114 do not necessarily have to be configured as ventilation paths having a predetermined cross section, and the air flow using the space on the back side of the drain tank 30 and the surrounding space of the filter unit 80 as shown in the figure. However, when such a space is used, a space where a main flow of air is generated can be used as a ventilation path.
In the filter unit 80, the air that has reached the filter unit suction port 82 first flows downward (in the negative direction of the Y axis) along the ventilation path 121, and forwards along the ventilation path 122 (in the positive direction of the Z axis). , And flows sideways along the ventilation path 123 (in the positive direction of the X axis) and gradually rearward along the ventilation path 124 (in the positive direction of the X axis and in the negative direction of the Z axis). , And flows upward along the ventilation path 125 (in the positive direction of the Y axis), and flows forward along the ventilation path 126 (in the positive direction of the Z axis) to reach the filter unit outlet 83.
Note that the cushioning material 201 shown in FIG. 23 and the cushioning material 202 shown in FIG. 26 are provided on the inner wall surface at a position where the air flowing in from the upstream ventilation path collides with the downstream ventilation path, buffering and absorbing noise. To do. Moreover, although not shown, noise can be reduced by providing a buffer material in the refracting portions of other ventilation paths in the same manner.

According to the present embodiment, the air passages 111 to 114 extending from the main body case suction port 101 to the filter unit suction port 82 by making the suction direction of the main body case suction port 101 different from the suction direction of the filter unit suction port 82. Therefore, the noise generated by the fan motor 51 can be reduced from propagating from the main body case suction port 101 to the outside.
In particular, as in this embodiment, by setting the suction direction of the main body case suction port 101 and the suction direction of the filter unit suction port 82 to face each other, the main body case suction port 101 reaches the filter unit suction port 82. Since the ventilation path has a bend of at least 180 degrees due to a plurality of bends, it is possible to further reduce the noise generated by the fan motor 51 from propagating from the main body case suction port 101 to the outside.
In addition, in the relationship between the suction direction of the main body case suction port 101 and the suction direction of the fan motor unit suction port 52, the same effect as the suction direction of the main body case suction port 101 and the suction direction of the filter unit suction port 82 is obtained. Play.
Further, in the ventilation paths 111 to 126 from the main body case suction port 101 to the filter unit suction port 82, for example, by forming a ventilation path in a direction other than the plane formed by the X-axis and the Y-axis, the fan motor 51 Noise propagation can be reduced. In the present embodiment, the case where the ventilation paths 111 to 114 from the main body case suction port 101 to the filter unit suction port 82 are formed with a plurality of refracting portions in the plane formed by the X axis and the Y axis has been described. However, the noise propagation of the fan motor 51 can be further reduced by forming the ventilation path in a direction other than the plane formed by the X-axis and the Y-axis.

Next, the configuration of the fan motor unit 50 will be described with reference to FIGS.
The fan motor unit 50 includes a fan motor 51, a vibration isolating material 54 that is in close contact with a part of the outer periphery thereof, and a lid 55 and a casing 56 that sandwich the fan motor 51 together with the vibration isolating material 54. The lid 55 covers the suction side of the fan motor 51, and the casing 56 covers the outlet side of the fan motor 51, so that the suction space 130 is inside the lid 55 and the discharge space 140 is inside the casing 56. Is forming. A circular vibration isolating plate 57A is disposed on the back side of the casing 56, that is, on the back side main body case 40B side. A sound absorbing material 57B is disposed between the fan motor 51 and the vibration isolating plate 57A. Moreover, the casing 56 and the back side main body case 40B are attached via a vibration isolating material 57C.
The suction space 130 is formed between the fan motor unit suction port 52 and the fan motor suction port 53 as a space having a plane area larger than the passage sectional area of the fan motor unit suction port 52. The lid 55 that forms the suction space 130 has a configuration in which a fan motor suction port 53 is provided in a substantially central portion and a fan motor unit suction port 52 is provided on one side. Furthermore the suction space 130, the first suction space 130A and the side opposite to the fan motor unit inlet port 52 than the fan motor inlet 53 formed in the fan motor unit suction port 52 side of the fan motor inlet 53 The inclined surface 55A is provided so that the first suction space 130A is larger than the second suction space 130B when divided into the second suction space 130B. Thus, by making the first suction space 130A larger than the second suction space 130B, the suction flow into the fan motor 51 is made smooth, so that the generation of noise is reduced and the performance of the fan motor 51 is improved. A decrease can be prevented.
Further, the inlet opening cross section of the fan motor unit suction port 52 is configured wider than the outlet opening cross section connected to the suction space 130, and the step portions 52R and 54R extending from the inlet opening to the outlet opening are configured by curved surfaces. . Thus, by making the stepped portions 52R, 54R from the inlet opening to the outlet opening of the fan motor unit suction port 52 into a curved surface shape, air turbulence can be prevented, and noise can be generated by smoothing the air flow. The performance of the fan motor 51 can be prevented from being lowered.

Next, the flow of air in the fan motor unit 50 will be described.
The air that has reached the filter unit outlet 83, that is, the air that has reached the fan motor unit suction port 52, first flows laterally (in the negative direction of the X axis) along the ventilation path 131 in the fan motor unit 50. By flowing backward (in the negative direction of the Z axis) along the ventilation path 132, the air is sucked into the fan motor suction port 53.
In the fan motor unit 50, the air discharged from the fan motor 51 first flows rearward (in the negative Z-axis direction) along the ventilation path 141, and laterally along the ventilation path 142 (minus in the X-axis). The air is blown out from the fan motor unit outlet 58.

According to the present embodiment, the air passage 126 continuing to the fan motor unit suction port 52 is parallel to the rotation axis of the fan motor 51, so that the air flowing through the air passage 132 and the air flowing through the air passage 126 face each other. Since it becomes a flow and has a bend of 180 degrees, it is possible to reduce the propagation of noise generated by the fan motor from the main body case suction port to the outside.
In addition, if the ventilation path 126 continuing to the fan motor unit suction port 52 is eliminated and the ventilation path 125 is made a ventilation path continuing to the fan motor unit suction port 52, the air in the ventilation path 125 continuing to the fan motor unit suction port 52 is used. The flow direction of the fan motor 51 is the same as the direction of rotation of the fan motor 51 (counterclockwise). By smoothing the air flow sucked into the fan motor 51, noise generation is reduced and the performance of the fan motor 51 is reduced. Can be prevented.

Below, the ventilation path from the fan motor unit blower outlet 58 to the jet outlet of the nozzle part 60 is demonstrated using FIGS. 30-31.
The air discharged from the fan motor unit outlet 58 passes through the heater 91, flows upward (in the positive direction of the Y axis) along the ventilation path 151, passes through the ventilation path 152 having the sound insulation walls 211 and 212, and By flowing upward (in the positive direction of the Y axis) along the ventilation path 153 and then flowing forward (in the positive direction of the Z axis) along the ventilation path 154, the nozzle section 60 is reached, and the ventilation path in the nozzle section 60 Along the lower side (minus direction of the Y-axis) and ejected.
Here, the sound insulating wall 211 is provided on one inner wall surface 40C, and the sound insulating wall 212 is provided on the other inner wall surface 40D. One inner wall surface 40C and the other inner wall surface 40D are wall surfaces facing each other. Further, a space 152A through which air flows is formed between the sound insulation wall 211 provided on one inner wall surface 40C and the other inner wall surface 40D, and the sound insulation wall 212 provided on the other inner wall surface 40D and the one inner wall surface 40C A space 152B through which air flows is formed between them. In addition, a space 152C through which air flows around the sound insulating wall 211 is formed at the side of the sound insulating wall 211, and a space 152D through which air flows around the sound insulating wall 212 is formed at the side of the sound insulating wall 212. The height of the sound insulating wall 211 provided on one inner wall surface 40C is larger than the size of the space 152B between the sound insulating wall 212 provided on the other inner wall surface 40D and the one inner wall surface 40C, The height dimension of the sound insulation wall 212 provided on the wall surface 40D is larger than the dimension of the space 152A between the sound insulation wall 211 provided on one inner wall surface 40C and the other inner wall surface 40D.
