Description

  The present invention relates to a water discharger that is used by being attached to the tip of a faucet, and more particularly to a water discharger that can arbitrarily set the water discharge direction.

2. Description of the Related Art Conventionally, water discharge devices having shower heads and the like that are used in a washstand and a kitchen sink have not only discharged water only in a certain direction but also various devices that can change the water discharge direction.
In the shower head holding structure of Patent Document 1, the end of the shower head is detachably inserted into the mounting base by mutual engagement of the locking portion of the mounting base and the locked portion of the shower head. It is worn. And in this engaging part, the swinging rotation position of the shower head with respect to the attachment base is positioned. Further, a rotating part for swinging the shower head is provided, and the shower head can be rotated while the shower head is inserted into the mounting base.

  In the shower head of Patent Document 2, a rotation restricting projection and a retaining groove are formed on the outer periphery of the insertion shaft of the shower head, and an insertion ring in which a fitting ring is inserted and fixed to a water discharge pipe into which the insertion shaft is inserted. Grooves are formed. When the insertion shaft is inserted into the water discharge pipe, a fitting ring is fitted to the outer periphery of the retaining groove so that the shower head does not fall off the water discharge pipe. Then, the rotation restricting projection comes into contact with any one of the contact surfaces on both ends of the fan-shaped recess formed on the inner periphery of the fitting ring, and the rotation angle range of the insertion shaft is restricted. .

  The hand-held shower of Patent Document 3 is attached so that the shower head can rotate around a rotation axis in a direction orthogonal to the connection surface at the connection surface where the shower head is gripped. A shower head bottom having a plurality of fountain nozzles is provided at a predetermined angle with respect to the rotation axis.

  In the water discharge device of Patent Document 4, in order to discharge a shower-like water discharge flow over a wide area while changing the water discharge trajectory, the head is relative to the central axis of the guide member that holds the cylinder of the head. While tilting and swinging, it rotates around its own central axis. In addition, the guide member holds the outer peripheral portion formed in a spherical shape with two O-rings in the holding member, and can change the direction of the central axis.

  In general, the water discharge device is often installed at the center of a wall surface of a bathroom or the like or the center of a sink. However, if the installation location of the water discharge device is not limited, it is possible to provide a water discharge device at a corner portion, particularly in a sink, so that the sink can be widely used. For this reason, it is calculated | required that the water discharge direction can be adjusted so that a water dischargeable area may become a wide surface shape instead of a linear or curved strip shape.

  However, the water dischargeable area by the shower head of Patent Document 1 is a belt shape obtained by the rotation of the shower head, and there is a problem that the water discharge direction cannot be changed in the front-rear direction toward the mounting base. The shower head of Patent Document 2 can freely change the direction of water discharge if the insertion state with respect to the water discharge pipe is removed, but at this time, the shower head must be held with one hand, and there is a problem that both hands cannot be used. .

  Moreover, although the shower head of patent document 3 can rotate 360 degree | times around a rotating shaft line, since the direction of a fountain nozzle is being fixed with the predetermined angle with respect to the rotating shaft line, the water dischargeable area becomes an annular surface. The water cannot be discharged in the rotation axis direction. Further, the radius of the annular surface cannot be changed. And in the water discharging apparatus of patent document 4, since the spherical-shaped guide member is hold | maintained by O-ring, the water dischargeable area can be made into planar shape, However, The change range of the water discharging direction is limited.

The rotating head is supported so as to be rotatable about a rotation axis in a direction orthogonal to the direction and to be positioned at the rotated position.

  According to the above configuration, since the rotating head is supported by the base portion so as to be rotatable around a rotation axis in a direction orthogonal to the faucet water discharge direction, the rotation head is rotated to change the water discharge direction. By changing, the water dischargeable area can be a wide band-like surface. Moreover, when rotating a base | substrate part or a part of base | substrate part, the strip | belt-shaped surface which can discharge water can be rotated, and the water dischargeable area can be expanded from strip | belt shape to circular shape.

It is connected movably, and the flow path in the flow path changing portion and the flow path in the rotating head are connected.

  According to a third aspect of the present invention, in the water discharge device according to the second aspect, the base portion is provided with a positioning member, and the positioning member is disposed at a position where the positioning member abuts on an end of the rotating shaft portion. It is characterized by that.

  According to a fourth aspect of the present invention, in the water discharge device according to the third aspect, an annular concavo-convex portion is formed on the rotating shaft portion, and on the other hand, a protrusion of an elastic piece arranged as the positioning member is the concavo-convex portion. The rotation position of the rotation head is positioned according to the pitch of the recess by entering the recess of the portion.

When the length of the connecting pipe portion 81 is set to an appropriate length, for example, even if the turning head 80 is turned around the turning shaft 21 within a range of 180 degrees, the water discharge head 82 contacts the main body portion 6. Is prevented.

And in this 2nd Embodiment, in addition to the effect in 1st Embodiment, the following effects can be acquired.
(5) In the above-described embodiment, the rotation shaft unit 61 and the water discharge head 82 are integrated into the rotation head 80 via the connecting pipe portion 81 having an appropriate length. For this reason, the rotation area of the rotation head 80 around the rotation shaft 21 can be increased.

(Example of change)
In addition, the said embodiment can also be changed and actualized as follows.
-Although the structure of the head holding part 9 of 1st Embodiment was made into the form which the rotation axis | shaft part 61 and the holding | maintenance part 62 couple | bonded through the coupling | bond part of slight length, the connection pipe part of 2nd Embodiment It should be connected via a connecting part of an appropriate length such as 81.
The water discharge head 10 of the first embodiment can be switched between straight water discharge and shower water discharge, but only for shower or for straight water discharge.
-Although the water discharge head 82 of 2nd Embodiment was only for showers, it should be switchable only for straight water discharge or straight water discharge and shower water discharge.
The protrusions 53 are formed at two places on the disk portion 51 of the elastic piece 13, but the protrusions 53 are formed only at one place.
