Aspects of the present invention generally relate to a washbasin unit and a method for installing the washbasin unit.

Washroom units equipped with hand dryers that dry wet hands by blowing out air are known. For example, Patent Document 1 discloses a hand dryer integrated with a washroom, which is provided above the washbasin with a water outlet that sprays wash water, an air outlet that blows out warm air to dry wet hands after washing, and a soapy liquid outlet that sprays soapy liquid.

Japanese Patent Application Laid-Open No. 2006-304926

The washbasin unit has, for example, a water spout that dispenses water, a liquid soap spout that dispenses liquid soap (soap liquid), and a dryer spout that dispenses air to dry wet hands. By arranging the water spout, liquid soap spout, and dryer spout side by side, usability and design can be improved.
The drying spout, for example, has a wide appearance from side to side and discharges a wide airflow in the left-right direction. This allows airflow to be discharged over a wide area of wet hands, improving usability. However, in such a washbasin unit, if the distance between the drying spout and the water spout or liquid soap spout is extremely short, the user may feel oppressed.

The present invention was developed in recognition of this issue, and aims to provide a washbasin unit and a method for installing the washbasin unit that can reduce the feeling of oppression felt by the user.

The first invention is a washbasin unit comprising a water spout that spouts water, a liquid soap spout that spouts liquid soap, and a flat, box-shaped dryer spout with a wide air outlet that spouts air, wherein the left-right width of the dryer spout is wider than the left-right widths of the water spout and the liquid soap spout, respectively, the water spout, the liquid soap spout, and the dryer spout are aligned left-right, one of the water spout and the liquid soap spout is located between the other of the water spout and the liquid soap spout and the dryer spout, and a first distance between the left-right center of the one of the water spout and the liquid soap spout and the left-right center of the dryer spout is longer than a second distance between the left-right center of the water spout and the liquid soap spout.

This washbasin unit prevents the distance between the drying spout and the water spout (or liquid soap spout) from becoming too short compared to the distance between the water spout and the liquid soap spout. This prevents the user from feeling oppressive, even if the drying spout is wide from side to side, and gives a clean impression.

The second invention is the first invention, further comprising a mounting structure having a first mounting portion to which the water spout is attached, a second mounting portion to which the liquid soap spout is attached, and a third mounting portion to which the drying spout is attached, wherein when the water spout is attached to the first mounting portion, the left-right center position of the water spout coincides with the left-right center position of the first mounting portion, and when the liquid soap spout is attached to the second mounting portion, the left-right center position of the liquid soap spout coincides with the left-right center position of the second mounting portion, and the drying spout When attached to the third mounting portion, the horizontal center position of the drying spout coincides with the horizontal center position of the third mounting portion, the first mounting portion, the second mounting portion, and the third mounting portion are aligned in the horizontal direction, one of the first mounting portion and the second mounting portion is located between the other of the first mounting portion and the second mounting portion and the third mounting portion, and a third distance between the horizontal center position of one of the first mounting portion and the horizontal center position of the third mounting portion is longer than a fourth distance between the horizontal center position of the first mounting portion and the horizontal center position of the second mounting portion.

With this washbasin unit, the distance between the drying spout and the water spout (or liquid soap spout) is prevented from becoming extremely short compared to the distance between the water spout and the liquid soap spout, compared to when the first, second, and third mounting parts are arranged at equal intervals in the left-right direction. This prevents the user from feeling oppressive, even when the drying spout is wide, and gives a neat impression.

The third invention is a washbasin unit according to the second invention, wherein the mounting structure is part of the washbasin, the drying spout has one end on the side of the water discharge spout and another end opposite the one end, and the other end overlaps with the bowl surface of the washbasin in the vertical direction.

With this washbasin unit, even if the first distance is long, it is easy to ensure that the air from the drying spout is blown toward the inside of the bowl surface, making it easier to prevent water from splashing outside the bowl surface. Therefore, it is possible to reduce the feeling of oppression while also suppressing water splashing.

The fourth invention is a washbasin unit according to any one of the first to third inventions, characterized in that the width of the drying spout is 50 millimeters or more and 100 millimeters or less, the width of the water spout and the width of the liquid soap spout are 50 millimeters or less, and the first distance is greater than 1.0 times and less than 1.2 times the second distance.

With this washbasin unit, the width of the drying spout is between 50 and 100 millimeters, making it easier to blow air over a wide area of the user's hands, improving usability. Even when using such a drying spout, the first distance is greater than 1.0 and less than 1.2 times the second distance, making it easier to reduce the feeling of pressure and water splashing.

The fifth invention is a washbasin unit according to any one of the first to fourth inventions, characterized in that the vertical position of the upper end of the drying spout is approximately the same as the vertical position of the upper end of the water spout and the vertical position of the upper end of the liquid soap spout, and the front-to-rear position of the front end of the drying spout is approximately the same as the front-to-rear position of the front end of the water spout and the vertical position of the front end of the liquid soap spout.

This washbasin unit allows for improved design.

The sixth invention is a method for installing a washbasin unit in which a water spout that spouts water, a liquid soap spout that spouts liquid soap, and a flat, box-shaped dryer spout with a wide air outlet that spouts air are attached to a mounting structure, wherein the left-to-right width of the dryer spout is wider than the left-to-right widths of the water spout and the liquid soap spout, respectively, one of the water spout and the liquid soap spout is positioned between the other of the water spout and the liquid soap spout and the dryer spout, and the water spout, the liquid soap spout, and the dryer spout are arranged side by side in the left-to-right direction so that a first distance between the left-to-right center of the one of the water spout and the liquid soap spout and the left-to-right center of the dryer spout is longer than a second distance between the left-to-right center of the water spout and the liquid soap spout.

This method of installing the washbasin unit prevents the distance between the dryer spout and the water spout (or liquid soap spout) from becoming extremely short compared to the distance between the water spout and the liquid soap spout. This prevents the user from feeling oppressive, even if the dryer spout is wide from side to side, and gives a clean impression.

This aspect of the present invention provides a washbasin unit and a method for installing the washbasin unit that minimizes the feeling of oppression felt by the user.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, like components are designated by like reference numerals and detailed descriptions thereof will be omitted where appropriate.
1 is a perspective view illustrating a washbasin unit equipped with a hand dryer according to an embodiment. As shown in FIG. 1, the washbasin unit (hand drying system) according to the embodiment includes a hand dryer 100, a water discharger 130, and a liquid soap dispenser 150.

The hand dryer 100 has a drying spout 10, a drying function unit 20, and an air supply duct 30. The water discharger 130 has a water discharge spout 40 and a water function unit 45. The liquid soap discharger 150 has a liquid soap spout 50 and a liquid soap function unit 55.

The drying spout 10, the water spout 40, and the liquid soap spout 50 are attached to the mounting structure 80. In this example, the mounting structure 80 is part of the washbasin 81. The washbasin 81 is, for example, a wall-mounted type made of ceramic and is attached to the wall W1 inside the room. The washbasin 81 is, for example, in contact with the wall W1. Alternatively, the washbasin 81 may be attached to the counter C1.

The washbasin 81 has a bowl portion 82 (washbowl) and a wall portion 83. The bowl portion 82 has a downwardly curved, concave bowl surface 82f. The bowl surface 82f receives water discharged from the spout 40. A drain hole 82p is provided at the bottom of the bowl surface 82f, and water discharged onto the bowl surface 82f is drained through the drain hole 82p. The wall portion 83 extends upward from the rear end of the bowl surface 82f. The wall portion 83 has a wall surface 83f facing forward.

The drying spout 10, the water spout 40, and the liquid soap spout 50 are each attached to the wall 83 above the washbasin. The drying spout 10, the water spout 40, and the liquid soap spout 50 are located above the bowl surface 82f and are arranged apart from each other in the left-right direction.

Each spout (drying spout 10, water spout 40, liquid soap spout 50) has a cylindrical or box-shaped appearance and is provided with a discharge port for discharging liquid or gas and an internal flow path for guiding the supplied liquid or gas to the discharge port. Each spout extends forward from wall surface 83f.

In the description of the embodiment, the direction in which the drying spout 10 attached to a wall extends from the wall is referred to as "forward." In other words, "forward" is the direction in which the wall surface on which the drying spout 10 is provided faces. "Rear," "left side," and "right side" are directions seen from a user facing "forward." Furthermore, "upper" and "lower" are directions seen from a user standing in front of the drying spout 10.

The mounting structure 80 to which the drying spout 10 of the hand dryer 100 according to the embodiment is attached does not necessarily have to be a washbasin. The mounting structure 80 may be, for example, an appropriately provided panel or cabinet. That is, the wall to which the drying spout 10 is attached may be the wall of a panel or the wall of a cabinet. In this example, the wall surface of the wall to which the drying spout 10 is attached extends vertically. However, the wall surface of the wall to which the drying spout 10 is attached is not limited to a surface extending vertically. For example, the angle between the wall surface of the wall to which the drying spout 10 is attached and the vertical direction is ±50° or less.

The drying function unit 20, water function unit 45, and liquid soap function unit 55 are each attached to the wall W1 below the washbasin 81. In this example, in the space below the washbasin 81, the drying function unit 20 is located on the lower right side, the liquid soap function unit 55 is located on the upper right side, and the water function unit 45 is located on the left side. However, the arrangement of the drying function unit 20, water function unit 45, and liquid soap function unit 55 is not limited to this. For example, the drying function unit 20, water function unit 45, and liquid soap function unit 55 may be placed on the floor.

FIG. 2 is a block diagram illustrating a hand dryer according to an embodiment.
The drying spout 10 has an air outlet 10a and a sensor 10s. The air outlet 10a discharges a wide air stream F diagonally downward and forward. As will be described later, discharging a wide air stream corresponds to the length of the air outlet 10a in the left-right direction being longer than the length of the air outlet 10a in the front-to-rear direction.

Sensor 10s detects the user's hands. Sensor 10s (and sensors 40s and 50s, described below) can be, for example, a microwave sensor, an infrared light-emitting/receiving distance sensor, or a pyroelectric sensor. Sensor 10s is positioned so that it can detect the user's hands, for example, within the range where air is blown out from drying spout 10. The detection range D of sensor 10s faces, for example, diagonally downward and forward.

The drying function unit 20 has a heater 21, a blower 22 (electric blower), and a control unit 23 (drying control unit). The control unit 23 is electrically connected to the sensor 10s, the heater 21, and the blower 22, and controls the operation of the sensor 10s, the heater 21, and the blower 22. The control unit 23 uses an electrical circuit including, for example, a microcomputer.

The blower 22 has, for example, an electric fan, and sends air to the drying spout 10 via the air duct 30. The heater 21 is provided in the air passage between the blower 22 and the air duct 30, and appropriately heats the air sent from the blower 22 to the air duct 30. The air duct 30 connects the drying function unit 20 and the drying spout 10, and supplies the air sent from the blower 22 to the drying spout 10.

For example, when a user holds their hand below the drying spout 10, the sensor 10s enters a detection state, detecting the user's hand. The control unit 23 then operates the blower 22 and heater 21 based on the detection result (output signal indicating the detection state) of the sensor 10s. This causes air (warm air) to be supplied from the blower 22 to the air supply duct 30. The air supply duct 30 directs the supplied air toward the drying spout 10. The air supplied to the drying spout 10 passes through an air passage within the drying spout 10 and is discharged from the air outlet 10a. The user can dry their wet hands by blowing the air over their hands. For example, air continues to be discharged while the sensor 10s detects the presence of the user's hand. If the user moves their hand from below the drying spout 10 out of the detection range of the sensor 10s, the sensor 10s no longer detects the user's hand and enters a non-detection state. Then, based on the detection result of the sensor 10s (output signal indicating a non-detection state), the control unit 23 stops the operation of the blower 22 and heater 21. This stops the supply of air to the drying spout 10 and stops the discharge of air from the air outlet 10a.

FIG. 3 is a front view illustrating the washbasin unit according to the embodiment.
As shown in FIG. 3 , the water function unit 45 is connected to the water spout 40 via a water supply pipe 46. The water spout 40 is equipped with a water outlet 40a that discharges water downward and a sensor 40s that detects the user's hand. The water function unit 45 includes a control circuit, a hot water heater, a solenoid valve, and other components. When a user holds their hand below the sensor 40s, the sensor 40s enters a detection state, detecting the user's hand. The control circuit then controls the solenoid valve and hot water heater based on the output of the sensor 40s (an output signal indicating the detection state). This allows water (hot water) to be supplied from the water function unit 45 to the water spout 40 via the water supply pipe 46. The water supplied to the water spout 40 is then discharged from the water outlet 40a. For example, water continues to be discharged while the sensor 40s detects the presence of the user's hand. When the user moves their hand from below the water spout 40 out of the detection range of the sensor 40s, the sensor 40s no longer detects the user's hand and enters a non-detection state. In the water function unit 45, the control circuit controls the solenoid valve, hot water heater, etc. based on the detection result of the sensor 40s (the output signal indicating the non-detection state). This stops the discharge of water from the water outlet 40a.

The liquid soap function unit 55 is connected to the liquid soap spout 50 via a liquid soap supply pipe 56 and an air supply pipe 57. The liquid soap spout 50 is equipped with a discharge port 50a that discharges liquid soap downward and a sensor 50s that detects the user's hand. The liquid soap function unit 55 includes a control circuit, a liquid soap tank, a pump, and other components. When a user holds their hand below the sensor 50s, the sensor 50s enters a detection state, detecting the user's hand. In the liquid soap function unit 55, the control circuit then controls the pump and other components based on the output result (output signal indicating the detection state) of the sensor 50s. This causes liquid soap to be supplied from the liquid soap tank to the liquid soap spout 50 via the liquid soap supply pipe 56. The liquid soap supplied to the liquid soap spout 50 is discharged from the discharge port 50a. For example, liquid soap is discharged each time the sensor 50s detects the user's hand.

The height (vertical position) of the top end of the drying spout 10, the height of the top end of the water spout 40, and the height of the top end of the liquid soap spout 50 are, for example, the same. By aligning the top ends, the design can be improved.

FIG. 4 is a plan view illustrating the washbasin unit according to the embodiment.
4, the front end 10f of the drying spout 10 is located rearward of the center 82C in the front-to-rear direction of the bowl surface 82f when the drying spout 10 is attached to the wall surface 83f side of the wall portion 83. In other words, the length L10 in the front-to-rear direction of the drying spout 10 is shorter than half the length L82C of the bowl surface 82f in the front-to-rear direction.

Similarly, in Figure 4, the front end 40f of the water spout 40 and the front end 50f of the liquid soap spout 50 are located rearward of the center 82C. For example, the front ends 10f, 40f, and 50f are all located at the same front-to-rear positions. In this manner, each spout in this embodiment is compactly arranged on the bowl portion 82. The spouts extend forward from the wall surface 83f and are lined up on the left and right sides of the bowl portion 82, improving usability, while the compactness of the spouts improves design.

In this example, the drying spout 10 is positioned to the left of the liquid soap spout 50 and the water-dispensing spout 40. The water-dispensing spout 40 is also positioned between the drying spout 10 and the liquid soap spout 50. However, the order of the spouts is not limited to this. For example, the drying spout 10 may be positioned to the right of the liquid soap spout 50 and the water-dispensing spout 40. The liquid soap spout 50 may also be positioned between the drying spout 10 and the water-dispensing spout 40.

FIG. 5 is a perspective view illustrating a drying spout of the hand drying device according to the embodiment.
6(a) to 6(c) are plan views illustrating examples of drying spouts of hand drying devices according to embodiments.
6(a) is a top view, FIG. 6(b) is a front view, and FIG. 6(c) is a bottom view.

The drying spout 10 is attached to the wall 83 of the washbasin 81 by a holding member 61 (mounting member 60). Note that the washbasin 81 is omitted from Figure 5.

The drying spout 10 has a flat, box-shaped configuration. That is, the drying spout 10 has a flat, box-shaped cover 11 (outer shell member). In other words, when the drying spout 10 is viewed from the front as shown in FIG. 6(b), the length L1 in the left-right direction of the cover 11 is longer than the length L2 in the direction perpendicular to the left-right direction of the cover 11 (e.g., the up-down direction).

The cover 11 has a front surface 11f, a top surface 11t, a bottom surface 11b, a right side surface 11m, and a left side surface 11h.
The top surface 11t is a generally rectangular surface that extends in the front-rear and left-right directions and faces upward.
The front surface 11f extends downward from the front end of the top surface 11t and faces forward.
The right side surface 11m extends downward from the right end of the top surface 11t and faces rightward. The left side surface 11h extends downward from the left end of the top surface 11t and faces leftward. In this example, the right side surface 11m is a curved surface that convex to the right, and the left side surface 11h is a curved surface that convex to the left.

The lower surface 11b has a front region 11p, a left region 11q, and a right region 11r. The front region 11p extends rearward from the lower end of the front surface 11f and faces downward. The front region 11p has an inclined surface that slopes downward from the front to the rear.
The left region 11q extends from the lower end of the left side surface 11h toward the right and faces downward. The left region 11q is inclined downward from the left side toward the right side.
The right region 11r extends leftward from the lower end of the right side surface 11m and faces downward. The right region 11r is inclined downward from the right side to the left side.
The left region 11q and the right region 11r intersect at the center of the cover 11 in the left-right direction.

The air outlet 10a is located in the front part of the underside 11b. For example, as shown in Figure 6(c), the left-right length L3 of the air outlet 10a is longer than the front-rear length L4 of the air outlet 10a. In this example, the air outlet 10a is divided into five outlets 10b in the left-right direction. However, the number of outlets 10b is not limited to five and can be any number. Furthermore, the air outlet 10a does not have to be divided into multiple outlets.

One end 30a of the air duct 30 (see Figure 6(a)) extends forward and is connected to the rear side of the drying spout 10. In other words, the opening of one end 30a of the air duct 30 faces forward and is connected to the drying spout 10. The inner diameter L5 of one end 30a of the air duct 30 is shorter than the left-right length L3 of the air outlet 10a. The air supplied to the drying spout 10 from one end 30a of the air duct 30 spreads left-right in the air path within the drying spout 10 and is discharged from the air outlet 10a, which is long left-right. In this way, the air outlet 10a discharges a wide shaped wind.

FIG. 7 is a perspective view illustrating a part of the washbasin unit according to the embodiment.
Fig. 7 shows a portion of the washbasin unit as seen from behind the washbasin 81. That is, Fig. 7 shows the back side of the washbasin 81. Note that Fig. 7 omits the illustration of some elements such as the water discharge spout 40, the liquid soap spout 50, the water supply pipe 46, and the liquid soap supply pipe 56.

FIG. 8 is a cross-sectional view illustrating a drying spout of the hand drying device according to the embodiment.
FIG. 8 shows a cross section taken along line A1-A1 shown in FIG.
FIG. 9 is an exploded view illustrating the drying spout of the hand drying device according to the embodiment.
7, a recess 83c recessed forward is provided on the rear side of the wall 83 of the washbasin 81. As a result, a space SP1 (space within the recess 83c) is formed between the indoor wall W1 (see FIG. 1) and the washbasin 81 on the back side of the wall surface 83f.

A downward-facing opening 83d is provided at the bottom of the washbasin 81. Space SP1 is connected to the space below the washbasin 81 via opening 83d.

The wall portion 83 (wall surface 83f) is provided with first to third mounting portions 71 to 73 to which spouts are attached. In this example, the first to third mounting portions 71 to 73 are holes that penetrate the wall portion 83. The first to third mounting portions 71 to 73 are aligned in a straight line extending in the left-right direction. The water spout 40 is attached to the first mounting portion 71, the liquid soap spout 50 is attached to the second mounting portion 72, and the drying spout 10 is attached to the third mounting portion 73.

As shown in FIG. 8, the hand dryer 100 has an attachment member 60 that attaches the drying spout 10 to the wall portion 83. The attachment member 60 has a retaining member 61, a setscrew 64 (a pull-out prevention member), and a spacer 65 (a spacer member). The retaining member 61 is attached to the third attachment portion 73, and the drying spout 10 is held (supported) by the retaining member 61. The retaining member 61 is composed of a base 62, which is a cylindrical metal fitting, and a nut 63 for fixing the metal fitting. The base 62 has a cylindrical portion 62a and a flange portion 62b provided at the rear end of the cylindrical portion 62a. The nut 63 threads onto the cylindrical portion 62a. The inner diameter of the through hole that is the third attachment portion 73 is larger than the outer diameter of the cylindrical portion 62a and smaller than the outer diameter of the flange portion 62b. When the cylindrical portion 62a is inserted into the third mounting portion 73 from the rear of the wall portion 83, the flange portion 62b on the rear end abuts against the rear surface of the wall portion 83 via the O-ring 61r. With the cylindrical portion 62a inserted into the third mounting portion 73 (hole in the wall surface 83f) from the rear of the wall portion 83 in this manner, the wall portion 83 is sandwiched between the flange portion 62b on the rear side of the wall portion 83 and the nut 63 on the front side of the wall portion 83. In this way, the holding member 61 is attached to the wall portion 83. The drying spout 10 is attached to the holding member 61 using a set screw or the like.

When attached to the third mounting portion 73, the holding member 61 has a protruding portion 61p (see Figure 8) that protrudes from the wall portion 83. In this example, the protruding portion 61p is the tip of the cylindrical portion 62a and the nut 63. For example, an opening is provided at the rear end of the cover 11, and the rear end of the cover 11 covers the protruding portion 61p. In other words, the protruding portion 61p is inserted into the opening at the rear end of the cover 11. In this state, the holding member 61 holds the cover 11. The rear end of the cover 11 is in contact with, for example, the wall surface 83f.

Set screws 64 (see Figure 8) are inserted into the cover 11 from the circumferential direction of the cover 11. The circumferential direction of the cover 11 is a direction perpendicular to the front-to-rear direction, and in this example, is downward. The tip of the set screw 64 abuts against the nut 63. For example, the set screw 64 is a retaining member (set screw) that prevents the cover 11 from coming loose from the retaining member 61. The set screw 64 determines the position of the cover 11 relative to the retaining member 61, and secures the cover 11 to the retaining member 61.

As shown in FIG. 7, the air supply duct 30 connected to the rear side of the drying spout 10 passes inside the third mounting portion 73 (and the holding member 61) and curves downward and to the right from the third mounting portion 73 in the space SP1. The air supply duct 30 curves further downward within the space SP1 and extends through the opening 83d to the drying function unit 20. In this way, the air supply duct 30 curves up and down and left and right in the space SP1 behind the wall surface 83f, connecting the drying spout 10 and the drying function unit 20 after passing through the space SP1.

Similarly, the water spout 40, liquid soap spout 50, water supply pipe 46, and liquid soap supply pipe 56 are also attached. That is, the water spout 40 is attached to the first mounting part 71 using a retaining member 61w (e.g., a cylindrical metal fitting and nut). The rear end of the outer member of the water spout 40 is in contact with, for example, wall surface 83f. The water supply pipe 46 is connected from the rear side of the water spout 40 to the water function part 45, passing through the inside of the first mounting part 71 (and the retaining member 61w inserted into the first mounting part 71), space SP1, and opening 83d.
The liquid soap spout 50 is attached to the second mounting portion 72 using a retaining member 61s (e.g., a cylindrical metal fitting and nut). The rear end of the outer casing of the liquid soap spout 50 is in contact with, for example, the wall surface 83f. The liquid soap supply pipe 56 passes from the rear side of the liquid soap spout 50 through the inside of the second mounting portion 72 (and the retaining member 61s inserted into the second mounting portion 72), the space SP1, and the opening 83d, and is connected to the liquid soap function portion 55.

Note that at least a portion of each spout may be attached directly or indirectly to the wall portion 83. In the above example, each spout is indirectly attached to the wall portion 83 via a retaining member. In other words, each spout is indirectly held (supported) by the wall portion 83 via a retaining member. However, the method of attaching each spout to the wall portion 83 is not limited to the above. Each spout may also be held (supported) directly by the wall portion 83.

Furthermore, each holding member may hold the cover of each spout directly or indirectly. That is, for example, the holding member may directly hold the spout cover by contacting the spout cover. Alternatively, for example, a spacer member may be provided between the cover and the holding member, and the holding member may indirectly hold the spout cover via the spacer member. For example, in Figure 8, a spacer 65 is disposed between the inner periphery of the cover 11 and the nut 63. The spacer 65 is attached to the cover 11 with screws 66a and 66b (see Figure 9). The holding member 61 holds the spacer 65 by contacting it. At least a portion of the cover 11 is held by the holding member 61 via the spacer 65.

Furthermore, the first to third mounting portions 71 to 73 may have any configuration to which each spout can be attached. For example, the first to third mounting portions 71 to 73 are not limited to circular through-holes. The mounting portion to which the spout is attached may be one to which the spout is indirectly attached via a holding member or the like, as described above, or one to which the spout is directly attached. The mounting portion may directly hold the spout by contacting it; for example, the mounting portion may be configured so that part of the spout is inserted into the through-hole that serves as the mounting portion.

As shown in FIG. 7, the air supply duct 30 has a first duct 31 and a second duct 32. The air supply duct 30 may further have a connecting member 33 (connecting duct) and a cylindrical connecting member 34 (elbow duct) (see FIG. 3).

The second pipe 32 is connected downstream of the first pipe 31 in the air path for air sent from the blower 22 to the drying spout 10. At least a portion of the second pipe 32 is disposed in the space SP1. One end of the second pipe 32 is connected to the drying spout 10, and the other end of the second pipe 32 is connected to one end of the first pipe 31 via a connecting member 33. The other end of the first pipe 31 is connected to the drying function unit 20 via a connecting member 34. A member such as a hose clamp is used as appropriate for the connection.

The first pipeline 31, the second pipeline 32, and the connecting members 33 and 34 may be made of materials such as rubber or resin. For example, a corrugated hose may be used for the first pipeline 31, and a rubber hose may be used for the second pipeline 32.

As shown in FIG. 8, the drying spout 10 has a cover 11 and an air passage member 12 provided inside the cover 11. A nozzle cover 18 (lid) is provided on top of the air passage member 12 via a sealing member 17, making it airtight. The air passage member 12 serves as an air passage that guides air supplied from the air supply duct 30 to the air outlet 10a.

The air passage member 12 has a connection portion 13, an air outlet 10a, and an air diffusion chamber 15. The connection portion 13 is located at the rear end of the air passage member 12 and is the portion to which the air supply duct 30 is connected. One end 30a of the air supply duct 30 is connected to the connection portion 13 while extending forward. The connection portion 13 is, for example, cylindrical, and the outer diameter of the connection portion 13 is smaller than the inner diameter of the one end 30a of the air supply duct 30. The connection portion 13 is inserted into the opening of the air supply duct 30. In this state, the connection portion 13 is secured by a clamp 13p.

The air outlet 10a is located at the tip of the air passage member 12 and blows out air supplied to the air passage member 12 from the air supply duct 30. The air diffusion chamber 15 is located between the connection part 13 and the air outlet 10a, on the air path for the air blown out from the air outlet 10a. The air diffusion chamber 15 guides the air supplied from the connection part 13 to the air outlet 10a.

The left-right width of the air diffusion chamber 15 and the left-right width of the air outlet 10a are each larger than the inner diameter of one end 30a of the air supply duct 30. Air supplied to the air diffusion chamber 15 from the air supply duct 30 via the connection part 13 spreads vertically and horizontally within the air diffusion chamber 15 and is blown out from the air outlet 10a.

For example, a barrier portion 47 is provided within the air diffusion chamber 15. In this example, the barrier portion 47 is a portion of the bottom surface of the air passage member 12 that protrudes upward. The barrier portion 47 is located in front of the opening at one end 30a of the air supply duct 30. As a result, at least a portion of the air that flows into the air diffusion chamber 15 from the air supply duct 30 hits the barrier portion 47 and spreads in the vertical and horizontal directions. By providing the barrier portion 47 in this manner, the air can be spread efficiently within the air diffusion chamber 15. This makes it easier to discharge a uniformly wide airflow in the horizontal direction from the air outlet 10a.

The sensor 10s is positioned below the barrier portion 47 within the cover 11. The sensor 10s is covered from below by a first sensor cover 19a. A second sensor cover 19b is further attached around the first sensor cover 19a. The lower surfaces of the first sensor cover 19a and second sensor cover 19b form part of the lower surface 11b of the cover 11.

As mentioned above, in this example, the air outlet 11a, connection portion 13, and air diffusion chamber 15 are provided in the air passage member 12, which is separate from the cover 11. However, this is not limited to the above, and each portion of the drying spout 10 may be molded as a single unit as appropriate. The drying spout 10 may also be divided into multiple components as appropriate and assembled.

10A and 10B are front views illustrating a part of the washbasin unit according to the embodiment.
10(a) and 10(b) are diagrams illustrating a method for installing a washbasin unit according to an embodiment. Fig. 10(a) shows a washbasin 81 before spouts are installed. Fig. 10(b) shows the washbasin 81 after the spouts are installed.

As shown in FIG. 10(a), the first mounting portion 71, the second mounting portion 72, and the third mounting portion 73 are circular. The diameter of the third mounting portion 73 is larger than the diameters of the first mounting portion 71 and the second mounting portion 72. The diameters of the first mounting portion 71 and the second mounting portion 72 may be the same.

The center P73 of the third mounting portion 73 is lower than the center P71 of the first mounting portion 71 and the center P72 of the second mounting portion 72. The height of the center P71 of the first mounting portion 71 and the height of the center P72 of the second mounting portion 72 may be the same.

As shown in Figure 10(b), the left-right width (length along the left-right direction) W10 of the drying spout 10 is wider than the left-right width W40 of the water-dispensing spout 40 and the left-right width W50 of the liquid soap spout 50. The width W40 and the width W50 may be the same.

When the water spout 40 is attached to the first attachment portion 71 , the left-right center position C40 of the water spout 40 coincides with the left-right center position C71 of the attachment portion 71 .
When the liquid soap spout 50 is attached to the second mounting portion 72 , the left-right center position C50 of the liquid soap spout 50 coincides with the left-right center position C72 of the second mounting portion 72 .
When the drying spout 10 is attached to the third attachment portion 73 , the left-right center position C10 of the drying spout 10 coincides with the left-right center position of the third attachment portion 73 .
The "center position in the left-right direction" refers to the position in the left-right direction of the midpoint between the right end and the left end. Furthermore, for each spout, the center position in the left-right direction of the spout and the center position in the left-right direction of the attachment portion may be slightly misaligned due to manufacturing variations, play during assembly, etc. In other words, "matching" does not only mean that the two elements perfectly match, but also includes cases where the distance between the two elements is slight (for example, between 0 mm and 2.0 mm).

In this embodiment, one of the water spout 40 and the liquid soap spout 50 is positioned between the other of the water spout 40 and the liquid soap spout 50 and the drying spout 10. The first distance between the left-right center position of the one of the water spouts 40 and the liquid soap spout 50 and the left-right center position of the drying spout 10 is longer than the second distance between the left-right center position of the water spout 40 and the left-right center position of the liquid soap spout 50.

For example, in the example of Figure 10(b), the water spout 40 is between the liquid soap spout 50 and the dryer spout 10. The distance La (first distance) between the center position C40 and the center position C10 is longer than the distance Lb (second distance) between the center position C40 and the center position C50. This prevents the distance Lc between the dryer spout 10 and the water spout 40 from becoming extremely short compared to the distance Ld between the water spout 40 and the liquid soap spout 50.

In this embodiment, one of the first mounting portion 71 and the second mounting portion 72 is disposed between the other of the first mounting portion 71 and the second mounting portion 72 and the third mounting portion 73. The third distance between the left-right center position of the one of the first mounting portion 71 and the left-right center position C73 of the third mounting portion 73 is longer than the fourth distance between the left-right center position of the first mounting portion 71 and the left-right center position of the second mounting portion 72.

That is, in the example of Figure 10(a), the first mounting portion 71 is between the second mounting portion 72 and the third mounting portion 73. The distance Le (third distance) between the center position C71 and the center position C73 is longer than the distance Lf (fourth distance) between the center position C71 and the center position C72. This prevents the distance Lc between the drying spout 10 and the water spout 40 from becoming extremely short compared to the distance Ld between the water spout 40 and the liquid soap spout 50. Note that in this example, the third distance is the same as the first distance, and the fourth distance is the same as the second distance.

In addition, in this embodiment, the positions of the first mounting portion 71 and the second mounting portion 72 may be interchanged, thereby interchangeing the positions of the water spout 40 and the liquid soap spout 50. In this case, the second mounting portion 72 is between the first mounting portion 71 and the third mounting portion 73. The liquid soap spout 50 is between the water spout 40 and the dryer spout 10. The distance between the left-right center of the liquid soap spout 50 and the left-right center of the dryer spout 10 (first distance) is longer than the distance between the left-right center of the water spout 40 and the left-right center of the liquid soap spout 50 (second distance). The distance between the left-right center of the second mounting portion 72 and the left-right center of the third mounting portion 73 (third distance) is longer than the distance between the left-right center of the first mounting portion and the left-right center of the second mounting portion (fourth distance). This prevents the distance between the dryer spout 10 and the liquid soap spout 50 from becoming extremely short compared to the distance between the water discharge spout 40 and the liquid soap spout 50.

For example, a configuration in which the first mounting portion 71, the second mounting portion 72, and the third mounting portion 73 are arranged at equal intervals in the left-right direction is also conceivable. However, in this case, because the drying spout 10 is wider than the water spout 40 and the liquid soap spout 50, the distance between the drying spout 10 and the water spout 40 (or the liquid soap spout) may be significantly shorter than the distance between the water spout 40 and the liquid soap spout 50. This may cause the user to feel pressured. In contrast, according to the embodiment, the first distance is longer than the second distance, and the third distance is longer than the fourth distance. This prevents the distance between the drying spout 10 and the water spout 40 or the liquid soap spout 50 from becoming significantly shorter than the distance between the water spout 40 and the liquid soap spout 50, compared to when the first mounting portion 71, the second mounting portion 72, and the third mounting portion 73 are arranged at equal intervals in the left-right direction. This prevents the user from feeling pressured, even when the drying spout is wide, giving a clean impression.

As shown in Figure 10(b), the drying spout 10 has one end 10p and the other end 10q in the left-right direction. One end 10p is the end on the side of the spout 40. The other end 10q is the end opposite 10p. In other words, one end 10p is located between the other end 10q and the spout 40 in the left-right direction. The other end 10q overlaps with the bowl surface 82f of the washbasin 81 (see Figure 1 or Figure 4) in the up-down direction.

For example, if the first distance (third distance) is too long, the other end 10q of the drying spout 10 may not overlap the bowl surface 82f. In other words, if the third mounting portion 73 is too far left-right from the first mounting portion 71, part of the drying spout 10 may be located outside the bowl surface 82f. In such a case, wind from the drying spout 10 may be blown outward from the bowl surface 82f, and water on the user's hands or other surfaces may be blown outward by the wind and scattered outside the bowl surface 82f.

In contrast, in this embodiment, the other end 10q overlaps the bowl surface 82f of the washbasin 81 in the vertical direction. This makes it easier to blow air from the drying spout 10 toward the inside of the bowl surface 82f, even if the first distance (third distance) is relatively long, making it easier to prevent water from splashing outside the bowl surface 82f. Therefore, it is possible to reduce the feeling of oppression while also suppressing water splashing.

In this example, the drying spout 10, the water spout 40, and the liquid soap spout 50 each overlap substantially entirely with the bowl surface 82f in the vertical direction.

The width W10 is, for example, 50 mm (millimeters) or more and 100 mm or less. The width W40 and the width W50 are each 25 mm or more and 50 mm or less. For example, the width W10 is 3 times or more and 5 times or less than the width W40 or the width W50. The first distance (e.g., distance La) is preferably greater than 1.0 times and less than 1.2 times the second distance (e.g., distance Lb).
When the width W10 is 50 mm or more and 100 mm or less, air can be easily blown over a wide area of the user's hand, improving usability. Even when such a drying spout 10 is used, when the first distance is greater than 1.0 times and less than 1.2 times the second distance, it is easier to suppress the feeling of pressure and the splashing of water.

For example, as shown in Figure 10(b), the vertical position of the upper end 10t of the drying spout 10 is approximately the same as the vertical position of the upper end 40t of the water spout 40, and is approximately the same as the vertical position of the upper end 50t of the liquid soap spout 50. Here, "approximately the same" in relation to the vertical position means that the distance between them is 0 mm or more and 3 mm or less. Also, as explained with reference to Figure 4, the front-to-back position of the front end 10f of the drying spout 10 is approximately the same as the front-to-back position of the front end 40f of the water spout 40, and is approximately the same as the front-to-back position of the front end 50f of the liquid soap spout 50. Here, "approximately the same" in relation to the front-to-back position means that the distance between them is 0 mm or more and 2 mm or less.
