Description

[Technical Field]

[0001] Aspects of the present invention generally relate to vanity units and methods of installing vanity units. [Background technology]

[0002] There are known washbasin units equipped with hand dryers that dry wet hands by blowing air. For example, Patent Document 1 discloses a hand dryer integrated with a washbasin, which has a water outlet for discharging wash water, an air outlet nozzle for drying wet hands with warm air after washing, and a soapy liquid outlet for discharging soapy liquid, all located above the washbasin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-304926 Summary of the Invention [Problem to be solved by the invention]

[0004] 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.

[0005] The present invention was made based on the recognition of such problems, and aims to provide a washbasin unit and an installation method for the washbasin unit that can reduce the feeling of oppression felt by the user. [Means for solving the problem]

[0006] 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 drying spout with a wide air outlet that spouts air, wherein the left and right width of the drying spout is wider than the left and right widths of the water spout and the liquid soap spout, respectively, the water spout, the liquid soap spout and the drying spout are aligned left and 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 drying spout, and a first distance between the left and right center position of one of the water spout and the liquid soap spout and the left and right center position of the drying spout is longer than a second distance between the left and right center position of the water spout and the liquid soap spout.

[0007] This washbasin unit prevents the distance between the dryer 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 dryer spout is wide, and gives a clean impression.

[0008] A second invention is the first invention, further comprising a mounting structure having a first mounting part to which the water spout is attached, a second mounting part to which the liquid soap spout is attached, and a third mounting part to which the drying spout is attached, wherein when the water spout is attached to the first mounting part, the left-right center position of the water spout coincides with the left-right center position of the first mounting part, and when the liquid soap spout is attached to the second mounting part, the left-right center position of the liquid soap spout coincides with the left-right center position of the second mounting part, and the drying spout This washbasin unit is characterized in that, when attached to the third mounting part, the left-right center position of the drying spout coincides with the left-right center position of the third mounting part, the first mounting part, the second mounting part and the third mounting part are aligned left-right, one of the first mounting part and the second mounting part is located between the other of the first mounting part and the second mounting part and the third mounting part, and a third distance between the left-right center position of one of the first mounting part and the left-right center position of the third mounting part is longer than a fourth distance between the left-right center position of the first mounting part and the left-right center position of the second mounting part.

[0009] With this washbasin unit, the distance between the drying spout and the water spout (or the liquid soap spout) is prevented from becoming too 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.

[0010] The third invention is a washbasin unit characterized in that, in the second invention, 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.

[0011] With this washbasin unit, even if the first distance is long, the airflow from the drying spout can be easily directed toward the inside of the bowl, making it easier to prevent water from splashing outside the bowl. This makes it possible to reduce the feeling of oppression while also preventing water from splashing outside.

[0012] The fourth invention is a washbasin unit characterized in that, in any one of the first to third inventions, 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.

[0013] 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 and improving usability. Even when using such a drying spout, the first distance is more than 1.0 and less than 1.2 times the second distance, making it easier to reduce the feeling of pressure and water splashing.

[0014] The fifth invention is a washbasin unit characterized in that, in any one of the first to fourth inventions, 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-back position of the front end of the drying spout is approximately the same as the front-to-back position of the front end of the water spout and the front-to-back position of the front end of the liquid soap spout.

[0015] This washbasin unit can improve the design.

[0016] 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 drying spout having a wide air outlet that spouts air are attached to a mounting structure, wherein the left and right width of the drying spout is wider than the left and 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 drying spout, and the water spout, the liquid soap spout, and the drying spout are arranged side by side in the left and right direction so that a first distance between the left and right center position of one of the water spout and the liquid soap spout and the left and right center position of the drying spout is longer than a second distance between the left and right center position of the water spout and the liquid soap spout.

[0017] This method of installing the washbasin unit prevents the distance between the dryer 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 dryer spout is wide, and gives a neat impression. [Effects of the Invention]

[0018] According to the aspects of the present invention, a washbasin unit and a method for installing the washbasin unit are provided that can reduce the feeling of oppression felt by the user. [Brief explanation of the drawings]

[0020] 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 drying device according to an embodiment. As shown in FIG. 1, the washbasin unit 200 (hand drying system) according to the embodiment includes a hand drying device 100, a water discharger 130, and a liquid soap discharger 150.

[0021] 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.

[0022] The drying spout 10, the water spout 40, and the liquid soap spout 50 are attached to a mounting structure 80. In this example, the mounting structure 80 is part of a washbasin 81. The washbasin 81 is, for example, a wall-mounted type made of ceramic and attached to a wall W1 inside the room. The washbasin 81 is in contact with the wall W1, for example. Alternatively, the washbasin 81 may be provided on a counter C1.

[0023] Washbasin 81 has bowl portion 82 (washbowl) and wall portion 83. Bowl portion 82 has a concave bowl surface 82f that curves downward. Bowl surface 82f receives water discharged from spout 40. A drain hole 82p is provided at the bottom of bowl surface 82f, and water discharged onto bowl surface 82f is drained through drain hole 82p. Wall portion 83 extends upward from the rear end of bowl surface 82f. Wall portion 83 has a wall surface 83f that faces forward.

[0024] The drying spout 10, the water spout 40, and the liquid soap spout 50 are each attached to a 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.

[0025] Each spout (drying spout 10, water spout 40, liquid soap spout 50) has a cylindrical or box-like 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.

[0026] 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, "upward" and "downward" are directions seen from a user standing in front of the drying spout 10.

[0027] 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.

[0028] The drying function unit 20, the water function unit 45, and the 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 at the lower right side, the liquid soap function unit 55 is located at 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, the water function unit 45, and the liquid soap function unit 55 is not limited to this. For example, the drying function unit 20, the water function unit 45, and the liquid soap function unit 55 may be placed on the floor.

[0029] 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.

[0030] The sensor 10s detects the user's hand. The sensor 10s (and sensors 40s and 50s described below) may be, for example, a microwave sensor, an infrared light emitting / receiving distance measuring sensor, or a pyroelectric sensor. The sensor 10s is disposed so as to be able to detect the user's hand, for example, within the range where air is discharged from the drying spout 10. The detection range D of the sensor 10s faces, for example, diagonally downward and forward.

[0031] 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 operations of the sensor 10s, the heater 21, and the blower 22. The control unit 23 uses an electric circuit including, for example, a microcomputer.

[0032] 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.

[0033] For example, when a user holds their hand below the drying spout 10, the sensor 10s enters a detection state in which it has detected the user's hand. Then, the control unit 23 operates the blower 22 and the heater 21 based on the detection result (output signal indicating the detection state) of the sensor 10s. This causes air (hot air) to be supplied from the blower 22 to the air supply duct 30. The air supply duct 30 guides the supplied air to 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 onto their hands. For example, the air supply continues while the sensor 10s detects the presence of the user's hand. When 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 (an output signal indicating a non-detection state), the control unit 23 stops the operation of the blower 22 and the heater 21. This stops the supply of air to the drying spout 10, and stops the discharge of air from the air outlet 10a.

[0034] 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 provided 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. In the water function unit 45, the control circuit then controls the solenoid valve, hot water heater, and other components based on the output result (output signal indicating the detection state) of the sensor 40s. This causes water (hot water) to be supplied from the water function unit 45 via the water supply pipe 46 to the water spout 40. The water supplied to the water spout 40 is 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. Then, 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 (output signal indicating the non-detection state). This stops the discharge of water from the water outlet 40a.

[0035] The liquid soap function unit 55 is connected to the liquid soap spout 50 by a liquid soap supply pipe 56 and an air supply pipe 57. The liquid soap spout 50 is provided 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, etc. When a user holds their hand below the sensor 50s, the sensor 50s enters a detection state in which it has detected the user's hand. In the liquid soap function unit 55, the control circuit then controls the pump, etc. based on the output result of the sensor 50s (output signal indicating the detection state). As a result, liquid soap is 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.

[0036] The height (vertical position) of the upper end of the drying spout 10, the height of the upper end of the water spout 40, and the height of the upper end of the liquid soap spout 50 are, for example, the same. By making the heights of the upper ends the same, the design can be improved.

[0037] 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 of the drying spout 10 in the front-to-rear direction is shorter than half the length L82C of the bowl surface 82f in the front-to-rear direction.

[0038] 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 positioned the same in the front-to-rear direction. In this manner, each spout in this embodiment is compactly provided 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.

[0039] In this example, the drying spout 10 is positioned to the left of the liquid soap spout 50 and the water-spouting spout 40. Furthermore, the water-spouting spout 40 is 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-spouting spout 40. Furthermore, the liquid soap spout 50 may be positioned between the drying spout 10 and the water-spouting spout 40.

[0040] 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 dryers according to embodiments. FIG. 6(a) is a top view, FIG. 6(b) is a front view, and FIG. 6(c) is a bottom view.

[0041] The drying spout 10 is attached to a wall 83 of a washbasin 81 by a holding member 61 (attaching member 60). Note that the washbasin 81 is omitted in FIG.

[0042] The drying spout 10 has a flat, box-like shape. That is, the drying spout 10 has a flat, box-like 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 of the cover 11 in the left-right direction is longer than the length L2 of the cover 11 in a direction perpendicular to the left-right direction (e.g., the up-down direction).

[0043] 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 substantially 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.

[0044] 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.

[0045] The air outlet 10a is located in the front part of the underside 11b. For example, as shown in FIG. 6(c), the length L3 of the air outlet 10a in the left-right direction is longer than the length L4 of the air outlet 10a in the front-rear direction. 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.

[0046] One end 30a (see FIG. 6(a)) of the air duct 30 extends forward and is connected to the rear side of the drying spout 10. In other words, the opening of the one end 30a of the air duct 30 faces forward and is connected to the drying spout 10. The inner diameter L5 of the one end 30a of the air duct 30 is shorter than the left-right length L3 of the air outlet 10a. The air supplied from the one end 30a of the air duct 30 to the drying spout 10 spreads left-right in the air path within the drying spout 10 and is discharged from the air outlet 10a, which is long in the left-right direction. In this way, the air outlet 10a discharges a wide shaped air stream.

[0047] FIG. 7 is a perspective view illustrating a part of the washbasin unit according to the embodiment. Figure 7 shows a portion of the washbasin unit as seen from behind the washbasin 81. That is, Figure 7 shows the back side of the washbasin 81. Note that Figure 7 omits the illustration of some elements such as the water discharge spout 40, liquid soap spout 50, water supply pipe 46, and liquid soap supply pipe 56.

[0048] FIG. 8 is a cross-sectional view illustrating a drying spout of a 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.

[0049] A downward-facing opening 83d is provided in the lower part of the washbasin 81. The space SP1 communicates with the space below the washbasin 81 via the opening 83d.

[0050] 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 on a straight line extending in the left-right direction. The water-dispensing 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.

[0051] 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 holding member 61, a setscrew 64 (a retaining member), and a spacer 65 (a spacer member). The holding member 61 is attached to the third attachment portion 73, and the drying spout 10 is held (supported) by the holding member 61. The holding 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 is screwed 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 side comes into contact with 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 (the 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 with a set screw or the like.

[0052] The holding member 61 has a protruding portion 61p (see FIG. 8) that protrudes from the wall portion 83 when attached to the third attachment portion 73. 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.

[0053] Set screws 64 (see FIG. 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 a nut 63. For example, the set screw 64 is a retaining member (set screw) that prevents the cover 11 from coming off the holding member 61. The set screw 64 determines the position of the cover 11 relative to the holding member 61, and fixes the cover 11 to the holding member 61.

[0054] 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 in the space SP1 and extends to the drying function unit 20 through the opening 83d. In this way, the air supply duct 30 curves in the up-down and left-right directions in the space SP1 behind the wall surface 83f, and connects the drying spout 10 and the drying function unit 20 after passing through the space SP1.

[0055] 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 attachment 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 passes from the rear side of the water spout 40 through the inside of the first attachment part 71 (and the retaining member 61w inserted into the first attachment part 71), space SP1, and opening 83d, and is connected to the water function part 45. 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) or the like. The rear end of the outer casing member of the liquid soap spout 50 is in contact with, for example, 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), space SP1, and opening 83d, and is connected to the liquid soap function portion 55.

[0056] At least a portion of each spout may be attached directly or indirectly to wall portion 83. In the above example, each spout is indirectly attached to wall portion 83 via a retaining member. In other words, each spout is indirectly held (supported) by wall portion 83 via a retaining member. However, the method of attaching each spout to wall portion 83 is not limited to the above. Each spout may also be held (supported) directly by wall portion 83.

[0057] 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 FIG. 8, a spacer 65 is disposed between the inner periphery of the cover 11 and a nut 63. The spacer 65 is attached to the cover 11 with screws 66a and 66b (see FIG. 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.

[0058] Furthermore, the first to third attachment portions 71 to 73 may have any configuration to which the respective spouts can be attached. For example, the first to third attachment portions 71 to 73 are not limited to circular through-holes. The attachment portions to which the spouts are attached may be those to which the spouts are indirectly attached via a holding member or the like as described above, or may be those to which the spouts are directly attached. The attachment portions may directly hold the spouts by contacting them, and may be configured, for example, so that part of the spout is inserted into the through-hole that serves as the attachment portion.

[0059] 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).

[0060] The second pipe 32 is connected to the downstream side of the first pipe 31 in the air path of the air sent from the blower 22 to the drying spout 10. At least a portion of the second pipe 32 is arranged 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.

[0061] Materials such as rubber or resin may be used for the first pipeline 31, the second pipeline 32, and the connecting members 33 and 34. For example, a bellows hose may be used for the first pipeline 31, and a rubber hose may be used for the second pipeline 32.

[0062] 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 the upper part 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.

[0063] 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 provided at the rear end of the air passage member 12 and is the portion to which the air duct 30 is connected. One end 30a of the air 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 duct 30. The connection portion 13 is inserted into the opening of the air duct 30. In this state, the connection portion 13 is secured by a clamp 13p.

[0064] Air outlet 10a is provided at the tip of air passage member 12 and blows out air supplied from air supply duct 30 to air passage member 12. Air diffusion chamber 15 is provided between connection part 13 and air outlet 10a on the air path of the air blown out from air outlet 10a. Air diffusion chamber 15 guides the air supplied from connection part 13 to air outlet 10a.

[0065] 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. The air supplied to the air diffusion chamber 15 from the air supply duct 30 via the connection part 13 spreads in the vertical and horizontal directions within the air diffusion chamber 15 and is blown out from the air outlet 10a.

[0066] For example, a barrier portion 47 is provided inside 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. Therefore, 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 inside the air diffusion chamber 15. This makes it easier to discharge a wide airflow that is uniform in the horizontal direction from the air outlet 10a.

[0067] The sensor 10s is disposed 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 the second sensor cover 19b form part of the lower surface 11b of the cover 11.

[0068] As described above, in this example, the air outlet 11a, the connection portion 13, and the 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 suitably molded as a single unit. The drying spout 10 may also be suitably divided into a plurality of members and assembled.

[0069] 10(a) and 10(b) 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 a washbasin 81 after spouts are installed.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] When the water spout 40 is attached to the first attachment part 71, the center position C40 of the water spout 40 in the left-right direction coincides with the center position C71 of the attachment part 71 in the left-right direction. When the liquid soap spout 50 is attached to the second attachment portion 72, the center position C50 of the liquid soap spout 50 in the left-right direction coincides with the center position C72 of the second attachment portion 72 in the left-right direction. When the drying spout 10 is attached to the third attachment portion 73, the center position C10 of the drying spout 10 in the left-right direction coincides with the center position of the third attachment portion 73 in the left-right direction. The "center position in the left-right direction" refers to the position in the left-right direction of the midpoint between the right and left ends. 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).

[0074] In this embodiment, one of the water spout 40 and the liquid soap spout 50 is disposed between the other of the water spout 40 and the liquid soap spout 50 and the drying spout 10. A first distance between the left-right center position of the one of the water spout 40 and the liquid soap spout 50 and the left-right center position of the drying spout 10 is longer than a 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.

[0075] 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 shorter than the distance Ld between the water spout 40 and the liquid soap spout 50.

[0076] In the 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. A third distance between the center position in the left-right direction of the one of the first mounting portion 71 and the second mounting portion 72 and a center position C73 in the left-right direction of the third mounting portion 73 is longer than a fourth distance between the center position in the left-right direction of the first mounting portion 71 and the center position in the left-right direction of the second mounting portion 72.

[0077] That is, in the example of Figure 10(a), the first attachment portion 71 is between the second attachment portion 72 and the third attachment 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 being extremely short compared to the distance Ld between the water spout 40 and the liquid soap spout 50. In this example, the third distance is the same as the first distance, and the fourth distance is the same as the second distance.

[0078] In the embodiment, the positions of the first and second mounting portions 71 and 72 may be interchanged, and the positions of the water spout 40 and the liquid soap spout 50 may be interchanged. In this case, the second mounting portion 72 is between the first and third mounting portions 71 and 73. The liquid soap spout 50 is between the water spout 40 and the drying spout 10. The distance between the left-right center position of the liquid soap spout 50 and the left-right center position of the drying spout 10 (first distance) is longer than the distance between the left-right center position of the water spout 40 and the left-right center position of the liquid soap spout 50 (second distance). The distance between the left-right center position of the second mounting portion 72 and the left-right center position of the third mounting portion 73 (third distance) is longer than the distance between the left-right center position of the first mounting portion and the left-right center position of the second mounting portion (fourth distance). This prevents the distance between the dry 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.

[0079] For example, a configuration in which the first attachment portion 71, the second attachment portion 72, and the third attachment portion 73 are arranged at equal intervals in the left-right direction is also conceivable. However, in this case, since 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 extremely short compared to the distance between the water spout 40 and the liquid soap spout 50. This may cause a feeling of oppression to the user. 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 being extremely short compared to the distance between the water spout 40 and the liquid soap spout 50, compared to when the first attachment portion 71, the second attachment portion 72, and the third attachment portion 73 are arranged at equal intervals in the left-right direction. This prevents the user from feeling oppressive even when the drying spout is wide from side to side, giving the user a neat and tidy impression.

[0080] As shown in FIG. 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, in the left-right direction, one end 10p is located between the other end 10q and the spout 40. The other end 10q overlaps with the bowl surface 82f of the washbasin 81 (see FIG. 1 or 4) in the up-down direction.

[0081] For example, if the first distance (third distance) is too long, the other end 10q of the drying spout 10 may not overlap with the bowl surface 82f. In other words, if the third attachment portion 73 is too far from the first attachment portion 71 in the left-right direction, a part of the drying spout 10 may be located outside the bowl surface 82f. In such a case, the wind from the drying spout 10 may be blown outward from the bowl surface 82f, and water on the user's hands or the like may be blown outward by the wind and scattered outside the bowl surface 82f.

[0082] In contrast, in the embodiment, the other end 10q overlaps with the bowl surface 82f of the washbasin 81 in the vertical direction. This makes it easy 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 easy to prevent water from splashing outside the bowl surface 82f. Therefore, it is possible to prevent water from splashing while reducing the feeling of oppression.

[0083] 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 up-down direction.

[0084] The width W10 is, for example, 50 mm (millimeters) or more and 100 mm or less. The width W40 and 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 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 water splashing.

[0085] For example, as shown in FIG. 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" with respect 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 FIG. 4, the front-to-rear position of the front end 10f of the drying spout 10 is approximately the same as the front-to-rear position of the front end 40f of the water spout 40, and is approximately the same as the front-to-rear position of the front end 50f of the liquid soap spout 50. Here, "approximately the same" with respect to the front-to-rear position means that the distance between them is 0 mm or more and 2 mm or less.

[0086] The above describes the embodiments of the present invention. However, the present invention is not limited to these descriptions. Design modifications made by a person skilled in the art to the above-described embodiments are also included within the scope of the present invention as long as they incorporate the features of the present invention.
