  It is desired that the faucet can discharge a sufficient amount of water over a wide range while realizing water saving. For example, when users wash their hands, the water discharged from the faucet covers the user's hand over a wide area and sufficiently hits the user's hand, so that the user feels high volume (a feeling of plenty) and a comfortable feeling. You can feel the goodness of

  In Patent Document 1, a wide range of water discharge is realized by performing shower-like water discharge. However, since the discharged water is in the form of a shower, the amount of water hitting the user's hand cannot be said to be sufficient, and the water pressure may be high, so that the user is less likely to feel a high sense of volume and good comfort.

  This invention is made | formed in view of the situation mentioned above, Comprising: It aims at providing the water faucet which can make a user feel a high feeling of volume and a good feeling of contact, implement | achieving water saving.

  The faucet according to the present invention comprises a water discharge pipe having a flow path through which water flows, and a water discharge opening formed in the water discharge pipe and communicating with the flow path, the water discharge opening being annular and membrane-like. It is composed of an annular slit that can discharge water.

  According to this invention, since it has the water discharge port which consists of a cyclic | annular slit which can discharge water circularly and membranously, annular and membranous water can be applied to a user. For this reason, it is possible to make the user feel a high volume feeling and a good feeling of hitting. Moreover, since the water discharged is annular and film-like, it is possible to perform water discharge spreading over a wide range with a small amount of water compared to one bundle of water discharge, and water saving can be realized.

In the above faucet, the water discharge pipe may be formed with a through-hole that is surrounded by the slit of the water discharge opening and penetrates the water discharge pipe.
According to the present invention, the water discharge pipe is formed with a through hole that is surrounded by the slit of the water discharge opening and penetrates the water discharge pipe. The water discharge state such as the amount of water can be visually confirmed. For this reason, the water discharge amount of the faucet is easily adjusted to an appropriate water discharge amount by the user, and water saving can be induced. In addition, when using a water faucet, the user can visually recognize the water discharge state through the through-hole formed in the water discharge pipe, so that the user feels better by visually appealing the water discharge state. Can be made. Furthermore, since the slit which comprises a water discharge port is formed so that a through-hole may be enclosed, a comparatively big cyclic | annular water discharge can be performed and a wide range water discharge can be performed with a small amount of water.

In the faucet, the slit of the water outlet may be formed on the inner peripheral surface of the through hole so as to surround the through hole.
According to this invention, since the slit which comprises a water outlet is formed in the internal peripheral surface of a through-hole so that a through-hole may be enclosed, at the time of use of a water faucet, a user tends to visually recognize a water outlet. For this reason, the water discharge amount of the faucet is easily adjusted to a more appropriate water discharge amount by the user, and water saving can be further induced. Moreover, since the water outlet is easy to visually recognize, the slits constituting the water outlet are easy to clean and have excellent cleanability.

In the faucet, the slit of the water discharge port may be formed on the lower surface of the water discharge pipe so as to surround the through hole.
According to the present invention, since the slit constituting the water discharge port is formed on the lower surface of the water discharge pipe so as to surround the through hole, the water discharge port itself is not visually recognized by the user when the water faucet is used. Only the water discharged from the water is visually recognized by the user through the through hole. For this reason, it is possible to clearly show the water discharge state to the user, and it is possible to further improve the feeling of volume and the feeling of contact that the user feels.

In the above faucet, the water discharge pipe may be substantially horizontal in a state where the water discharge pipe is attached at a predetermined position.
According to the present invention, in a state where the water discharge pipe (water faucet) is attached to a predetermined position such as a wash basin, the water discharge pipe in which the water discharge opening is formed becomes substantially horizontal, and therefore, the ring and the membrane form from the water discharge opening. Water can be discharged with good controllability.

  According to the faucet according to the present invention, it is possible to make the user feel a high volume feeling and a good feeling of hitting while realizing water saving.

Further, the water discharge pipe 4 is formed with a water discharge port 6 communicating with the flow path 5. The water discharge port 6 is configured by an annular slit 6d that can discharge the water W flowing through the flow path 5 in a ring shape and a film shape. Details of the spout 6 will be described later.

  The water discharge pipe 4 is formed with a through hole 8 that is surrounded by the slit 6d of the water discharge opening 6 and penetrates the water discharge pipe 4 in a direction intersecting with the direction in which the water discharge pipe 4 extends (vertical direction in FIG. 2). . More specifically, the water discharge pipe 4 is formed with a through hole 8 that penetrates the upper surface 4 a and the lower surface 4 b of the water discharge pipe 4, and the through hole 8 is surrounded by the slit 6 d of the water discharge port 6. The shape of the through hole 8 of the water discharge pipe 4 according to the present embodiment is a substantially square shape with rounded corners in plan view. The shape of the through hole 8 in plan view is not limited to a substantially square shape, and may be, for example, a circle or an ellipse.

FIG. 3 is a schematic cross-sectional view in which a part of the water discharge pipe 4 of the faucet 1 is enlarged.
As shown in FIGS. 1 to 3, an attachment member 7 constituting a part of the water discharge pipe 4 is attached to the faucet 1. An attachment member 7 is attached so as to press fit into a hole penetrating the upper surface 4a and the lower surface 4b of the water discharge pipe 4. The attachment member 7 is formed of an upper surface 7a, a lower surface 7b, an outer peripheral surface 7c, and an inner peripheral surface 7d. In the state where the attachment member 7 is attached, the upper surface 7 a of the attachment member 7 constitutes a part of the upper surface 4 a of the water discharge pipe 4, and the lower surface 7 b of the attachment member 7 constitutes a part of the lower surface 4 b of the water discharge pipe 4. Yes. In the present embodiment, the space defined by the inner peripheral surface 7 d of the attachment member 7 is the through hole 8 of the water discharge pipe 4. In this embodiment, the periphery of the outer peripheral surface 7 c of the attachment member 7 is a flow path 5, and the outer peripheral surface 7 c of the attachment member 7 constitutes a part of the flow path surface of the flow path 5.

The attachment member 7 according to the present embodiment is configured to be removable. For this reason, when cleaning the faucet 1, the attachment member 7 can be removed and the inside of the attachment member 7, the water discharge pipe 4, etc. can be cleaned, Therefore The faucet 1 is excellent in cleaning property.
The attachment means for attaching the attachment member 7 is not limited to press-fitting, and may be fitting or screwing.

  The attachment member 7 may be separated from each other between the portion including the upper surface 7a and the portion including the lower surface 7b, or may be connected to each other at a specific portion within a range that does not interfere with the annular and membrane-like water discharge described later. Good. For example, in this embodiment, the part including the upper surface 7a and the part including the lower surface 7b of the attachment member 7 are connected to each other at a part of the outer peripheral surface 7c.

  On the inner peripheral surface 7d of the attachment member 7 (inner peripheral surface of the through hole 8), a water discharge port 6 including an annular slit 6d is formed. The slit 6 d of the water discharge port 6 is formed so as to surround the through hole 8. The water discharge port 6 has a predetermined gap and is formed by a slit 6 d that is continuous without a break along the circumferential direction of the inner peripheral surface 7 d of the attachment member 7. A slit 6 c having a predetermined gap is formed on the outer peripheral surface 7 c of the attachment member 7. As shown in FIG. 3, the flow path 5 and the slit 6c communicate with each other, and the slit 6c and the slit 6d communicate with each other. That is, the flow path 5 and the water discharge port 6 (slit 6d) communicate with each other through the slit 6c.

  The effect | action at the time of use of the faucet 1 comprised as mentioned above is demonstrated. Below, the case where a user wash | cleans a hand using the water tap 1 is demonstrated to an example.

The user lifts the faucet 1 by lifting the handle lever 3 of the faucet 1. At this time, the user adjusts the lifting height of the tip of the handle lever 3 to adjust the amount of water W discharged. In addition, the user operates the handle lever 3 in the left-right direction to adjust the temperature of the water W to be discharged. A predetermined amount and temperature of water W is supplied from the faucet body 2 to the flow path 5 of the water discharge pipe 4 by the operation by the user. The water W flowing through the flow path 5 flows into the attachment member 7 from the slit 6c formed on the outer peripheral surface 7c of the attachment member 7, and from the slit 6d (water discharge port 6) formed on the inner peripheral surface 7d of the attachment member 7. Flows out. At this time, since the water discharge port 6 is constituted by the annular slit 6d, the annular and membrane-like water W is discharged from the water discharge port 6. More specifically, since the water discharge port 6 is configured by a slit 6d having a predetermined gap continuously continuous along the circumferential direction of the inner peripheral surface 7d of the attachment member 7, the water discharge port 6 has an annular and membrane-like shape. Water W is discharged.
When the user puts his / her hand into the ring-shaped and film-like water W, the water W is in a ring shape, and therefore the hand thus pushed out is covered with the water W over a wide area. Further, since the water W is in the form of a film, a sufficient amount of water W hits the hand that has been put out.
Further, the user visually recognizes the water discharge state of the water W through the through hole 8 formed in the water discharge pipe 4 while washing his / her hand.

For this reason, it is possible to make the user feel a high volume feeling and a good feeling of hitting. Moreover, since the water W to be discharged is annular and film-like, it is possible to perform water discharge spreading over a wide range with a small amount of water compared to one bundle of water discharge, and water saving can be realized.

  According to the faucet 1 according to the present embodiment, the water discharge pipe 4 is formed with the through hole 8 that is surrounded by the slit 6d of the water discharge opening 6 and penetrates the water discharge pipe 4, so that the water faucet 1 is used. The user can visually recognize the water discharge state such as the water discharge position and the water discharge amount through the through hole 8. For this reason, the water discharge amount of the faucet 1 is easily adjusted to an appropriate water discharge amount by the user, and water saving is easily induced. Moreover, since the water discharge state can be visually appealed to the user through the through-hole 8 formed in the water discharge pipe 4 when the faucet 1 is used, the sense of volume felt by the user can be further improved. Furthermore, since the slit 6d which comprises the water discharge port 6 is formed so that the through-hole 8 may be enclosed, a comparatively big cyclic | annular water discharge can be performed and a wide range water discharge can be performed with a small amount of water.

  According to the faucet 1 according to the present embodiment, since the slit 6d constituting the water discharge port 6 is formed on the inner peripheral surface of the through hole 8 so as to surround the through hole 8, when the faucet 1 is used, The user can easily see the spout 6. For this reason, the water discharge amount of the faucet 1 can be easily adjusted to a more appropriate water discharge amount by the user, and water saving can be further induced. Moreover, since the water discharge port 6 is easy to visually recognize, the slit 6d which comprises the water discharge port 6 can be cleaned, without removing the attachment member 7, and it is excellent in cleaning property.

In the faucet 1 according to the present embodiment, in the state where the faucet 1 (water discharge pipe 4) is attached to the attachment surface T, the water discharge pipe 4 is preferably substantially horizontal. Since the water discharge pipe 4 is substantially horizontal, the annular and film-like water can be discharged from the water discharge opening 6 (slit 6d) formed in the water discharge pipe 4 with good controllability.
In addition, as long as annular and membrane-like water can be discharged, the water discharge pipe may not be substantially horizontal in a state of being attached to the attachment surface T, and may be slightly inclined.

(Fourth embodiment)
Next, a faucet according to a fourth embodiment of the present invention will be described with reference to FIG.
The faucet according to this embodiment is different from the modification of the second embodiment in that it does not include a through hole.
FIG. 9 is an enlarged schematic cross-sectional view of a part of the water discharge pipe 4 of the faucet 100 according to the fourth embodiment of the present invention.

As shown in FIG. 9, an attachment member 47 constituting a part of the water discharge pipe 4 is attached to the faucet 100. An attachment member 47 is attached so as to press fit into a hole penetrating the lower surface 4b of the water discharge pipe 4. The attachment member 47 includes an upper surface 47a that contacts the water discharge pipe 4 including the upper surface 4a, a lower surface 47b that forms part of the lower surface 4b of the water discharge pipe 4, and an outer peripheral surface 47c that forms part of the flow path surface of the flow path 5. And is formed from.
In addition, the attachment member 47 is excellent in cleanability, and various attachment means can be employed, as with the attachment member 7 in the first embodiment.

In the faucet 100 according to the present embodiment, a through hole corresponding to the through hole 8 of the faucet 10A according to the modification of the second embodiment is not formed.
In the faucet 100 according to the present embodiment, no through hole penetrating the upper surface 4a of the water discharge pipe 4 is formed, and no through hole penetrating the upper surface 47a and the lower surface 47b of the attachment member 47 is formed.
The upper surface 47a of the attachment member 47 is in contact with the water discharge pipe 4 including the upper surface 4a. More specifically, the upper surface 47a of the attachment member 47 is in contact with the inner wall surface on the side where the upper surface 4a is located among the inner wall surfaces of the water discharge pipe 4 constituting the flow channel surface of the flow channel 5.
All other configurations are the same as the modification of the second embodiment.

  According to the faucet 100 according to the present embodiment, since the water discharge port 26 including the slit 26b capable of discharging the water W in an annular and membrane shape is provided, the annular and membrane water W can be applied to the user. For this reason, it is possible to make the user feel a high volume feeling and a good feeling of hitting. Moreover, since the water W to be discharged is annular and film-like, it is possible to perform water discharge spreading over a wide range with a small amount of water compared to one bundle of water discharge, and water saving can be realized.

  As mentioned above, although embodiment and modification of this invention were explained in full detail with reference to drawings, the concrete structure is not restricted to embodiment and modification, The change of the structure of the range which does not deviate from the meaning of this invention is carried out. , Combinations, deletions, and the like.

In the above-described embodiment and modification, the example in which the water discharge port including the annular slit is formed by attaching the attachment member has been described, but the method of forming the water discharge port is not limited thereto. For example, the spout may be formed by forming an annular slit in the surface of the lower surface 4b of the water discharge pipe 4 without using an attachment member. Moreover, without using an attachment member, the inner peripheral surface of the through-hole 8 of the water discharge pipe 4 is integrated with the upper surface 4a and the lower surface 4b of the water discharge pipe 4, and the predetermined inner surface is continuously continuous along the circumferential direction. You may form a water outlet by forming the slit which has a clearance gap.
In this case, since the attachment member is unnecessary, the number of faucet parts can be reduced. Furthermore, since the attachment member is not used, the appearance of the faucet can be made more beautiful.

  In the embodiment and the modification described above, either the water discharge port (slit) formed on the inner peripheral surface of the through hole 8 of the water discharge tube 4 or the water discharge port (slit) formed on the lower surface 4 b of the water discharge tube 4. Although an example has been described, one slit may be formed by combining both slits within a range in which annular and membrane-like water can be discharged. For example, a slit may be formed on the lower surface of the water discharge pipe at a portion near the distal end side of the water discharge pipe, and a slit may be formed on the inner peripheral surface of the through hole of the water discharge pipe at a portion near the faucet body of the water discharge pipe. . By combining both slits flexibly, it is possible to form an optimal water discharge port capable of discharging annular and film-like water according to the mounting surface to which the water tap is attached, the shape of the water discharge pipe of the water tap, and the like.

  In the embodiment and the modification described above, the example in which the water discharge port (slit) is formed with a predetermined gap has been described, but the width of the gap may not be constant. For example, by narrowing the width of the gap in a part of the annular spout, the amount of water discharged from the part can be reduced. Similarly, by increasing the width of the gap in a part of the annular water discharge port, the amount of water discharged from the part can be increased. In this case, in addition to the adjustment of the amount of water by the operation of the handle lever 3, the amount of water can be finely adjusted by the shape of the water outlet, so that the annular and membrane-like water can be discharged more suitably.

  In the above embodiment and the modification, the example in which the water discharge port (slit) is a continuous annular shape has been described. However, if water can be discharged in a ring shape and a film shape, a part of the water discharge port (slit) may be used. There may be breaks. For example, it may be a ring-shaped water outlet (slit) as a whole, having cuts at regular intervals within a range in which water can be discharged in the form of a ring and film.

In the drawings describing the embodiment and the modification, the faucet body 2 is drawn upright from the attachment surface T, and the water discharge pipe 4 is drawn so as to protrude straight and horizontally from the side surface of the faucet body 2. The shapes of the faucet body and the water discharge pipe are not limited to these. For example, the faucet body may extend while being inclined with respect to the attachment surface T, and may extend with a predetermined curvature from the lower end of the faucet body. Further, the water discharge pipe may be inclined and extended from the side surface of the faucet body, and may be substantially horizontal only in the region where the water discharge port at the tip of the water discharge pipe is formed, and has a predetermined curvature from the side surface of the water faucet body. It is good also as a substantially horizontal only the area | region where the water outlet of the front-end | tip part of a water discharge pipe is formed.
In the above embodiment and the modification, the example in which the water discharge pipe 4 is integrated with the faucet body 2 and the handle lever 3 has been described. However, the water discharge pipe is separate from the water faucet body and the handle lever. The structure attached to a mounting surface may be sufficient.
