Description

  The present invention relates to a water discharger rotary faucet that can be used as a faucet for hand washing, a faucet for brushing teeth, a mouthwash, etc.

A faucet is installed in an office washroom or the like. Usually, this faucet is a faucet dedicated to hand-washing, and is a faucet that only discharges water downward.
By the way, there are many people who use this faucet to brush their teeth during lunch breaks, etc. You have to pour and brush your teeth.
In this case, there is a problem that the faucet is not easy to use, and a place for placing the cup when not brushing teeth must be secured.

  Therefore, although a special faucet that discharges water upward for brushing teeth has been proposed, toothbrushing is mostly performed only during lunch breaks in offices, and it is overwhelming that faucets are used for hand washing at other times. Therefore, there is a problem that the efficiency of use is poor in the case of a faucet dedicated to brushing only for upward water discharge, which has a limited purpose and time of use.

  In this case, if the water discharge part on the tip side of the water discharge pipe is made to be a rotary type, when brushing teeth during lunch breaks, etc., the tooth discharge part should be faced upward and the water discharged from the water outlet should be used to effectively brush the teeth. In other cases, it is desirable that the water discharge portion be faced downward and water can be discharged downward from the water discharge port to perform actions such as hand washing.

However, the following problems arise when the water discharger is a rotary type.
That is, if the water discharge part is rotated upward while the water is discharged from the water discharge port, the water discharge part is turned sideways (that is, the water discharge port is turned sideways) and the water discharge is discharged sideways. This causes a problem that the water discharges from the floor and wets the floor.

Various types of faucets with a rotating water discharger have been proposed.
For example, in Patent Document 1 below, a water discharge valve is provided in the middle of the water discharge pipe so that the water discharge and the water stop can be switched by hand-operating the water discharge portion on the distal end side, and the water discharge unit is rotated. Has disclosed a faucet adapted to open and close the discharge valve.
However, the one disclosed in Patent Document 1 is not intended for upward water discharge and is different from the present invention.

Patent Document 2 below discloses a water faucet in which the water discharge portion is a rotary type and the water passage opening in the valve portion is closed when the water discharge port is turned sideways.
However, the faucet disclosed in Patent Document 2 is also not intended to discharge water upward, and the present invention is such that when the water discharge port is turned sideways, the valve opening is closed. Is different.

Further, in Patent Document 3 below, the water discharge portion on the tip end side of the water discharge pipe can be rotated, water is stopped when the water discharge port is turned sideways, and water is discharged from the water discharge port in the horizontal state. There has been disclosed a faucet adapted to prevent scattering around.
Unlike what is disclosed in Patent Document 1 and Patent Document 2 described above, the one disclosed in Patent Document 3 has a water discharge port facing upward and is scheduled to discharge water upward therefrom. This is different from the present invention in that water is stopped in the same manner as in Patent Document 2 when is turned sideways.

Japanese Patent No. 3462759 JP 2004-204600 A Japanese Utility Model Publication No. 62-55668

  In the background of the above situation, the present invention allows both downward and upward water discharge, and can be used as both a normal hand-washing faucet and a faucet for toothpaste, etc. A water faucet rotary faucet that does not cause a problem that the water is spouted from the water spout and the water spatters out of the hand-washing bowl and the like and the structure of the valve portion can be simplified. It was made for the purpose.

  Thus, according to the first aspect of the present invention, the water discharge portion having the water discharge port on the distal end side of the water discharge tube is rotatable with respect to the base portion, and the water discharge port is directed upward by the rotation of the water discharge portion. In the water faucet rotating faucet that enables upward water discharge and downward water discharge with the water discharge port facing downward, the movable side valve body that rotates together with the water discharge portion and the base portion is fixed. A valve portion provided with a side valve body, the movable side valve body is provided with a movable side opening for water passage, and the fixed side valve body is provided with a fixed side opening for water passage. In a state where the water discharge portion is at a rotation angle position other than the downward water discharge and the upward water discharge, a part of the movable side opening and the fixed side opening is an overlap area smaller than an overlap area at the time of the downward water discharge and the upward water discharge. It is supposed to overlap each other and secure water flow. It is characterized in.

  According to a second aspect of the present invention, in the first aspect, the valve portion is configured to enable downward water discharge and upward water discharge over a predetermined angle range in the rotation direction of the water discharge portion, and the downward water discharge. The angle range of upward water discharge is narrowed with respect to the angle range.

  According to a third aspect of the present invention, in the second aspect, the movable side opening and the fixed side opening are provided with first and second fan-shaped openings for downward water discharge and upward water discharge, The angle of the second fan-shaped opening for upward water discharge is made smaller than the angle of the first fan-shaped opening for downward water discharge.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the upper surface and the lower surface of the water discharge section are inclined with respect to the tube axis of the water discharge pipe, wherein the upper and lower thicknesses gradually decrease toward the tip. The inclined surface is provided until it reaches the tip, and the tip of the water discharger is formed as a knob with a flat shape extending horizontally in the inclined surface, and the discharge surface is formed on the inclined surface of the lower surface. A water mouth is provided.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the water discharge pipe protrudes forward at an angle that is upward with respect to the horizontal direction, and the water discharge port is directed downward with respect to the vertical direction. at an angle theta ₁ becomes forward obliquely downward angle, characterized in that to該鉛straight direction during upward spouting are defined is its orientation such that the front oblique upward angle at a small angle theta ₂ than the theta ₁ .

  A sixth aspect of the present invention is characterized in that, in any one of the first to fifth aspects, a main valve portion is provided on the upstream side of the valve portion for discharging water in the faucet body. .

Effects and effects of the invention

  As described above, the present invention has a valve portion including a movable side valve body and a fixed side valve body that rotate together with the water discharge section, and allows the water discharge section to rotate. The movable side opening and the fixed side opening are respectively provided with a fixed opening for water passage in the fixed side valve body, and in a state where the water discharge portion is at a rotational angle position other than downward water discharge and upward water discharge. Are partially overlapped with each other with an overlapping area smaller than the overlapping area at the time of downward water discharge and upward water discharge to ensure water flow.

  Such a water spouting part rotary faucet according to the present invention can be used for both downward and upward spouting. Therefore, it can be used as a normal faucet for hand-washing, as well as a faucet for brushing teeth and gargle. It can be used suitably.

When the faucet of the present invention is turned sideways under the water discharge state, the water faucet discharges without stopping even if the spout is turned to any angle other than downward or upward water discharge. It is characterized in that some water is discharged from the water mouth.
However, the momentum of the water discharge is weakened at times other than downward water discharge and upward water discharge, and the water discharge flow rate is reduced so that the water discharge does not jump out of the hand-washing bowl or the like.
That is, the faucet of the present invention always discharges water regardless of the direction of the water discharge port unless the upstream main valve portion is closed.

Normally, with a water faucet rotating type faucet, it is considered that water discharge is stopped when the water discharge port is turned sideways. In this case, if the upstream main valve portion remains open, the downstream valve portion (2 The primary pressure works on the secondary valve part.
Therefore, it is necessary to have a structure that can withstand the primary pressure on the secondary side of the valve part, and the structure of the valve part is complicated, and parts used for the valve part are also required to be pressure resistant. As a result, the cost required for the valve portion also increases.

In addition, if the secondary valve closes and the water discharge from the water outlet stops when the main valve is open, the user mistakes that the main valve is closed. I will judge.
More specifically, the operation unit that operates the main valve unit is erroneously determined to be currently closed.
At this time, even if the user wants to drain water and operates the operation unit, naturally water is not discharged from the water outlet, and the user erroneously determines that the faucet is out of order. Fear arises.

  However, even if the water discharge port is in a sideways state, it is possible to immediately determine that the main valve portion side, that is, the operation portion that operates the main valve portion is not currently closed, because the water discharge is performed slightly. Makes it possible to accurately recognize the current state of the faucet.

  On the other hand, in the present invention, when the water discharge port is in the horizontal direction, the flow rate of the water discharge is reduced. Therefore, when water is discharged from the water discharge port in the horizontal direction, the water discharge greatly jumps out from the hand-washing bowl in the horizontal direction. There is no problem of wetting the floor.

  Next, the second aspect of the present invention enables downward water discharge and upward water discharge over a predetermined angle range in the rotation direction of the water discharge portion, and narrows the angle range of upward water discharge relative to the angle range of downward water discharge. It is.

  In the case of upward water discharge, the water discharged upward from the water discharge port falls in a parabola. Therefore, if the angle range of the upward water discharge (the angle range in the rotation direction of the water discharge unit), specifically the angle range of the water discharge port capable of upward water discharge is made as wide as that of the downward water discharge, What does not jump out of the hand-washing bowl will spout the water farther in the left-right direction when water is discharged upward, and in some cases, the water discharge may jump out of the left-right direction from the hand-washing bowl.

  In this case, the angle range of the upward water discharge is made narrower than the angle range of the downward water discharge, and according to this second aspect, the water discharge jumps out of the hand-washing bowl in the left-right direction during the upward water discharge. Can be effectively prevented.

  On the other hand, when water is discharged downward, water can be discharged over a wide range of angles, so that it is possible to perform actions such as hand washing well, and this is also advantageously performed when hand-washing bowls are washed with downward water discharge. be able to.

In this case, one of the movable side opening of the movable side valve element and the fixed side opening of the fixed side valve element is provided with first and second fan-shaped openings for downward water discharge and upward water discharge, The angle of the second fan-shaped opening for upward water discharge can be made smaller than the angle of the first fan-shaped opening for downward water discharge.
By doing in this way, the angle range of upward water discharge can be easily made into a narrow range with respect to the angle range of downward water discharge.

  Next, according to a fourth aspect of the present invention, an inclined surface that gradually decreases the thickness of the water discharge portion toward the tip is provided on the upper and lower surfaces of the water discharge portion until reaching the tip, and the tip portion is flattened by these inclined surfaces. While being configured as a shape knob, the water outlet is provided on the inclined surface of the lower surface.

  According to the fourth aspect of the present invention, the user can rotate the water discharger with good operability by having a flat knob at the tip, and the water discharge port is provided on the inclined surface of the lower surface. Therefore, water splashed from the water outlet can flow along the inclined surface, and it is possible to satisfactorily prevent water from being collected around the water outlet.

Then claim 5, none shall projecting forward water discharge pipe at an angle forming an upward with respect to the horizontal direction and the water discharge port becomes forward obliquely downward angle at an angle theta ₁ with respect to the vertical direction when the downward water discharge, an upward When the water is discharged, the direction is determined so as to be an obliquely upward upward angle at an angle θ ₂ smaller than θ _{1 with} respect to the vertical direction. According to claim 5, when hand-washing is performed by discharging water downward Can discharge water forward at a large angle with respect to the vertical direction, and can perform a hand washing action well.

On the other hand, at the time of upward water discharge, it is possible to satisfactorily perform actions such as tooth brushing and gargle by discharging the water discharge at an obliquely upward upward angle with respect to the vertical direction.
In addition, since the discharge angle of the water discharge is smaller than that at the time of water discharge downward with respect to the vertical direction at this time, it is possible to prevent the water discharged from the front obliquely upward from jumping out from the front edge of the hand-washing bowl. can do.

In the present invention, a main valve part for carrying out spout water in the faucet body can be provided upstream of the valve part (Claim 6).
By doing in this way, the said valve part which controls a water flow according to rotation of a water discharging part can be comprised as a valve part of a secondary side, and it is favorable that the excessive load by a primary pressure is applied to the valve part Can be prevented.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, reference numeral 10 denotes a single lever faucet (hereinafter simply referred to as a faucet) of a water discharge section according to the present embodiment, which is erected at the back of a hand-washing bowl 15 (see FIG. 7).

The water discharge pipe 14 is divided into two in the tube axis direction, a water discharge part 20 on the distal end side having a water discharge port 18 and a base part 21 on the faucet body 12 side, which are connected to each other.
Here, the water discharger 20 can rotate 360 ° around the tube axis with respect to the base 21.

As shown in FIG. 2, the main valve portion 22 is built in the faucet body 12, and the lever operation portion 16 is operatively connected to the main valve portion 22.
In the faucet 10 of this example, the temperature of the discharged water is adjusted by rotating the lever operation part 16 left and right, and the flow rate of the discharged water and discharged water is adjusted by rotating the lever operation part 16 up and down.

  Here, the main valve portion 22 has a fixed side valve body made of a ceramic disk and a movable side valve body made of a ceramic disk sliding on the upper surface thereof. By sliding movement on the fixed valve body by the operation, the mixing ratio of the spout water and water and hot water is changed, thereby adjusting the temperature of the mixed water.

  Reference numeral 24 denotes a supply pipe for supplying water and hot water to the faucet body 12 (only one of the supply pipes is shown in the figure). The water and hot water sent through these supply pipes 24 are mainly used. It is mixed by the valve part 22 and flows out to the outflow path 26 in the faucet body 12, and further flows through the water discharge pipe flow path 28 and is discharged from the water discharge port 18.

In FIG. 2, 30 is a connection device for connecting the water discharger 20 and the base 21 and has a pair of joint pipes 32, 34 on the female side and the male side.
A downstream (secondary) valve portion 40 is provided with respect to the main valve portion 22, which has a fixed valve body 36 and a movable valve body 38, across the joint pipe 34 and the water discharge portion 20. ing.

In FIG. 3, the main part of the connection part by the connection device 30 is specifically shown together with the valve part 40.
As shown in the drawing, the fixed side valve body 36 and the movable side valve body 38 are both disc-shaped disc valve bodies made of resin.
The fixed-side valve body 36 has positioning protrusions 42 at three locations along the outer peripheral portion, and the joint pipe 34 is brought into a state where the positioning protrusions 42 are engaged with the positioning recesses 44 of the joint pipe 34. And is held in a fixed state.

On the other hand, the movable side valve body 38 is also provided with positioning projections 48 at three locations along the outer peripheral portion, and these positioning projections 48 are fitted into the fitting holes 52 so as to be engaged with the positioning recesses 50 of the water discharger 20. The water discharger 20 is held in an integrally rotated state.
In addition, the fixed side valve body 36 and the movable side valve body 38 are held inside the water discharge pipe 14 in a state in which the surfaces facing each other are in contact with each other.

In FIG. 3, reference numeral 54 denotes a clip (made of resin here) for locking the water discharger 20 in the retaining state, and has a pair of elastic engagement arms 56.
As shown in FIG. 4, the clip 54 is inserted into the insertion opening 58 of the water discharge pipe 14 and the insertion opening 60 of the joint pipe 34, and a pair of engagement arms 56 are formed in the water discharge section 20. By engaging with the annular engagement groove 62, the water discharger 20 is prevented from coming off the base 21.
The clip 54 itself is prevented from slipping downward from the water discharge portion 20 by elastically holding the groove bottom portion of the engagement groove 62 by the engagement arm 56.
In FIG. 3, 64 is a rubber O-ring for sealing.

As shown in FIG. 5, the fixed-side valve body 36 has a first fan-shaped opening 66 for downward water discharge on the lower side in the figure and an upper fan-shaped opening 68 for upward water discharge in the figure. Are respectively provided penetrating in the plate thickness direction.
A central hole 70 is provided in the central portion so as to communicate the openings 66 and 68.
Here, the central angle α ₂ of the upward water discharge opening 68 is a small angle with respect to the angle α ₁ of the downward water discharge central angle 66.

On the other hand, the movable valve body 38, a fan-shaped opening 72 having a central angle alpha ₃ further small angle of the center angle alpha ₂ of the opening 68 of the fixed valve body is provided through in the thickness direction.
Independently of this, a small circular center hole 74 is also provided in the central portion so as to penetrate in the thickness direction.

In this embodiment, as shown in FIG. 8, the water discharge pipe 14 protrudes forward at an angle β that is upward with respect to the horizontal direction.
The spout 18 becomes a forward and obliquely downward facing angle at an angle theta ₁ with respect to the vertical direction when the downward water discharge as indicated (A), the addition vertical direction during upward spouting as shown in (B) as a forward oblique upward angle at a small angle theta ₂ than theta ₁ with respect to its mounting orientation is defined, each angle downward spouting forms an upward spouting.

As shown in FIG. 8, inclined surfaces 76 and 78 inclined with respect to the tube axis of the water discharge pipe 14 are provided on the lower surface and the upper surface of the water discharge part 20 until the tip of the water discharge part 20 is reached. Yes.
As a result, the upper and lower thicknesses of the water discharger 20 become thinner toward the tip at the locations where the inclined surfaces 76 and 78 are provided, and the tip has a uniform thickness in the horizontal direction (downward discharge, upward discharge). In this state, the knob 80 has a flat shape extending in the horizontal direction.

In addition, the inclined surface 76 is determined at an inclination angle so as to be lowered to the right in the drawing with respect to the horizontal surface in the downward water discharge state.
Further, the inclined surface 76 has an inclination angle so as to be a surface inclined downward to the left in the drawing with respect to the horizontal plane even under the upward water discharge state shown in FIG.
On the other hand, the angle of inclination of the inclined surface 78 on the upper surface side is also determined so as to be a surface inclined downward in the drawing with respect to the horizontal plane under the upward water discharge state shown in FIG.

6 and 7 show the operation of the faucet 10 of the present embodiment.
In this embodiment, when the lever operation unit 16 is opened (water discharge start operation) with the water discharge unit 20 facing downward, the mixed water flowing out from the main valve unit 22 is discharged downward from the water discharge port 18.
In this embodiment, as shown in FIGS. 6 (A) and 7 (A), even when the water discharger 20 is rotated around the tube axis of the fixed angle water discharge pipe 14, the downward water discharge state is maintained. Can do.

Specifically, from the state in which the left edge of the opening 72 of the movable valve body 38 in the drawing coincides with the left edge of the opening 66 of the stationary valve body 36 in the drawing, the right edge of the opening 72 is the right side of the opening 66. Even if the water discharger 20 is rotated left and right around the tube axis within the angle range until it coincides with the edge, the mixed water is discharged downward from the water discharge port 18 at the same and maximum flow rate. Possible angular range of the downward water discharge is the angle alpha ₄ shown in FIG. 7 (A).
In this embodiment, the angle α ₄ is determined in advance such that the water discharged downward from the water outlet 18 does not jump out of the left and right sides of the hand-washing bowl 15.

Although the above is a state in which the opening 72 entirely overlaps the opening 66, water discharge is performed in a state where the amount of water is reduced even when the opening 72 partially overlaps the opening 66.
Then, as shown in FIG. 6B, water discharge through the openings 66 and 72 is stopped in a state where the opening 72 is completely inconsistent with the opening 66.
Thus the range of up to just before the water discharge through the openings 72,66 is stopped may be previously determined as the angle alpha _4.

  In this downward water discharge state, the center hole 70 of the fixed side valve body 36 and the center hole 74 of the movable side valve body 38 are in a state of being coincident (overlapping state). , 74 is discharged from the water outlet 18.

FIG. 6B and FIG. 7B show a state in the middle from the downward water discharge state until the water discharger 20 is rotated to the upward water discharge state.
At this time, the opening 72 of the movable valve body 38 does not coincide with any of the openings 66 and 68 of the fixed valve body 36, and therefore water is not discharged through the openings 66, 68 and 72 in this state.

  However, in this embodiment, the center hole 70 of the fixed side valve body 36 and the center hole 74 of the movable side valve body 38 are always in a state of being in communication with each other and being opened to the water discharge pipe channel 28. Therefore, even in this state, water passes through the fixed side valve body 36 and the movable side valve body 38, that is, the valve part 40 through the center holes 70 and 74, and the water that has passed through the valve part 40 passes through the water outlet 18. The water is discharged from.

FIG. 7B shows the state of water discharge at this time.
As shown in the figure, since the flow rate and the water flow at this time are weak, even if the water discharge port 18 is discharged in a horizontal state, the water discharge may jump out of the hand-washing bowl 15 in the left-right direction. There is no.

FIG. 6C and FIG. 7C show a state in which upward water discharge is performed through this state.
At this time, as shown in FIG. 6C, the opening 72 of the movable valve body 38 matches and overlaps the opening 68 of the fixed valve body 36, thereby ensuring water flow in the valve section 40. The water that has passed through the section 40 is discharged upward from the water outlet 18 where the water has turned upward.

In this upward water discharge, as shown in FIG. 6C, the opening 72 is formed from the angle at which the left edge of the opening 72 in the drawing and the left edge of the opening 68 coincide with each other. Upward water discharge is possible within an angular range until the right edge of the opening coincides with the right edge of the opening 68.
Angle range of the upward spouting at this time is alpha ₅ shown in FIG. 7 (C).

The angle alpha ₅ in the present embodiment, upward spouting water is are determined within a range that does not jump out hand-washing bowl 15 in the lateral direction.
Even in this upward water discharge, even when the opening 72 partially overlaps the opening 68, the upward water discharge can be performed with the flow rate reduced.
And when the opening 72 becomes completely inconsistent with the opening 68, the upward water discharge through the openings 72 and 68 is stopped.
Therefore it is also possible to have defined as the alpha ₅ within an angle range of up to immediately before.

As shown in FIG. 8, in this embodiment, in the downward water discharge state shown in (A), the direction of water discharge is an angle θ _{1 with} respect to the vertical direction. The direction is an angle θ ₂ smaller than the angle θ _{1 with} respect to the vertical direction.
In the present embodiment, both θ ₁ and θ ₂ are determined at angles at which the water discharge does not jump out beyond the front end of the hand-washing bowl.

  The faucet 10 of the present embodiment as described above is capable of both downward and upward spouting, and thus can be used as a normal hand-washing faucet or the like, as well as a faucet for toothbrushing and gargle. Can also be suitably used.

The faucet 10 of the present embodiment, when the water outlet 18 is turned sideways under the water discharge state, in detail, even if the water outlet 18 faces any angle other than downward water discharge and upward water discharge, Without watering, water is slightly discharged from the water outlet 18.
However, the momentum of the water discharge is weakened at times other than downward water discharge and upward water discharge, and the water discharge flow rate is reduced so that the water discharge does not jump out of the hand-washing bowl 15.
That is, the water faucet 15 of this embodiment always discharges water regardless of the direction of the water discharge port 18 as long as the upstream main valve portion 22 is not closed.

As described above, in the water faucet of the water discharger rotating type, it is considered that the water discharge is stopped when the normal water discharge port is turned sideways. In this case, in accordance with this embodiment, the upstream main valve portion 22 is opened. If left untreated, the primary pressure will act on the downstream valve portion (secondary valve portion) 40.
Therefore, it is necessary to make the secondary side valve portion 40 so as to be able to withstand the primary pressure, and the structure of the valve portion 40 is complicated, and the parts used for the valve portion 40 are also pressure resistant parts. Is required, and the cost required for the valve portion 40 is also increased.

In addition, when the secondary valve portion 40 is closed under the state where the main valve portion 22 is open, and the water discharge from the water discharge port 18 stops, the user closes the main valve portion 22. It is mistakenly determined that it is.
More specifically, it is erroneously determined that the lever operating unit 16 that operates the main valve unit 22 is currently closed.
At this time, even if the user wants to drain water and operates the lever operation unit 16, naturally the water is not discharged from the water outlet 18, and the user mistakenly assumes that the faucet 10 has failed. There is a risk of judgment.

  However, in the present embodiment, a slight amount of water is discharged even when the water discharge port 18 is in the sideways direction, so that the main valve portion 22 side, that is, the lever operation portion 16 that operates the main valve portion 22 is immediately determined to be not closed. Thus, the user can accurately recognize the current state of the faucet 10.

  On the other hand, in this embodiment, the water discharge flow rate is reduced when the water discharge port 18 is in the horizontal direction. Therefore, the water discharge is performed from the water discharge port 18 which is in the horizontal direction, so that the water discharge is greatly increased in the horizontal direction from the hand-washing bowl 15. The problem of jumping out and wetting the floor does not occur.

  Moreover, in this embodiment, while enabling downward water discharge and upward water discharge over the predetermined angle range in the rotation direction of the water discharge part 20, since the angle range of upward water discharge is narrowed with respect to the angle range of downward water discharge, it is upward. Even when the water discharge flies while drawing a parabola at the time of water discharge, there is no fear that the water discharge will jump out of the left and right direction from the hand-washing bowl 15.

  On the other hand, since it is possible to discharge water over a wide angle range at the time of downward water discharge, it is possible to perform actions such as hand washing well, and also to do this advantageously when washing the hand-washing bowl 15 with downward water discharge. Can do.

In the present embodiment, inclined surfaces 76 and 78 are provided on the upper and lower surfaces of the water discharger 18 so as to gradually reduce the thickness of the water discharger 20 toward the tip until the tip reaches the tip. Since the tip portion is configured as a flat-shaped knob 80 by 78, the user can hold the knob 80 to rotate the water discharger 18 with high operability.
Further, since the water discharge port 18 is provided on the inclined surface 76 on the lower surface, the water splashed from the water discharge port 18 can flow along the inclined surface 76, and water is collected around the water discharge port 18. It can prevent well.

Further in this embodiment, without those projecting forwardly at an angle forming a upward with respect to the horizontal direction the water discharge pipe 14, also the water discharge port 18 becomes forward obliquely downward angle at an angle theta ₁ with respect to the vertical direction when the downward water discharge, When the water is discharged upward, the direction is determined so that the angle is forward obliquely upward at an angle θ ₂ smaller than θ _{1 with} respect to the vertical direction. Water discharge can be discharged forward at an angle, and hand washing can be performed well.

On the other hand, at the time of upward water discharge, it is possible to satisfactorily perform actions such as tooth brushing and gargle by discharging the water discharge at an obliquely upward upward angle with respect to the vertical direction.
In addition, at this time, since the discharge angle of the water discharge is smaller than that at the time of water discharge downward with respect to the vertical direction, it is preferable that the water discharged diagonally forward and upward jumps out from the front edge of the hand-washing bowl 15. Can be prevented.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the above-described embodiment, the central hole 74 of the movable valve body 38 is provided independently of the fan-shaped opening 72, but the central hole 74 may be provided continuously with the opening 72 in some cases. .
Furthermore the angle alpha ₁ of the fan-shaped opening 66 for downward water discharge in the above embodiment, and the angle alpha ₂ of the fan-shaped opening 68 for upward water discharge is provided on the stationary-side valve body 36, the movable side which optionally It is also possible to provide on the valve body 38 side, and instead provide an opening 72 on the movable valve body 38 side on the fixed valve body 36 side.
In addition, this invention can be comprised in the form which added various change in the range which does not deviate from the meaning.
