DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
When the switching valve 62 attached to the hand is switched to the hand shower 54 side when the flow rate of the mixed hot water discharged from the water discharge port 53A is high, that is, when the water pressure is high, the knob 63 is lightly pulled up. However, there is a problem that the shower hose 57 moves violently due to strong water pressure at the moment when the mixed hot water is sprayed from the hand shower 54. In addition, since the water pressure applied to the faucet 53 is generally high in the hotel, when a mixed hot water is being discharged from the spout 53A, a slight gap is created between the main valve 66 and the start valve chamber 65A due to vibration or the like. High water pressure is applied to the start valve chamber 65A,
Since the starting valve 65 and the main valve 66 are lifted by the pushing force, they are suddenly switched to the hand shower 54 side, causing a problem that the shower hose 57 moves violently.

Therefore, in the present invention, when the water pressure applied to the faucet is higher than a predetermined value, the switching valve is prevented from switching to the hand shower side, so that the hand shower
The problem to be solved is to prevent the shower hose from moving violently under high water pressure.

[0010]

According to the present invention, in order to solve the above problems, when the valve shaft is operated in the upward direction, water from the water supply source is injected from the hand shower while the valve shaft is in the downward direction. A discharge member having a switching valve that discharges water from a water supply source from a discharge port when operated, and a pressing member that is pressed against the valve shaft, and is arranged outside the pressing member, and water is discharged from the discharge port. With a configuration including a slide lock member that locks the valve shaft by sliding in a direction parallel to the valve shaft according to the pressure of water being discharged and pressing the pressing member toward the valve shaft side. is there. Further, a groove in which the pressing member is locked is formed on the outer peripheral surface of the valve shaft, or the pressing member is
The ball is fitted in a groove formed on the outer peripheral surface of the valve shaft.

[0011]

According to the water discharge plug having the above structure, the slide lock member slides in the direction parallel to the valve shaft according to the pressure of the water discharged from the discharge port, and presses the pressing member toward the valve shaft side. At the same time, since the valve shaft is locked when the water pressure exceeds a predetermined level, the operation of the switching valve with respect to the hand shower when the water pressure is high is limited, and the shower wheel of the hand shower is
It prevents the water from moving violently under high water pressure.

[0012]

Embodiments of the present invention will now be described with reference to the drawings. As described in the section of the prior art, a hotel or the like is provided with a water spout and a hand shower as shown in FIG. 5, and the water spout is supplied with hot water and cold water from a water source at a mixing portion. A switching valve that is operated when the mixed hot water is ejected from the spout or the hand shower is attached.

FIG. 1 is a cross-sectional view showing the structure of the switching valve 2 of the water discharge tap 1. The knob 3 of the switching valve 2 is in a depressed state, and the mixed hot water supplied from a mixing device (not shown). Is discharged from a discharge port (not shown) through the valve port 7. Further, FIG. 2 is an enlarged view of a main part of FIG. On the other hand, FIG. 3 is a cross section in which the knob 3 of the switching valve 2 is pulled up, the valve port 7 is closed by the main valve 6, and the mixed hot water is injected from a hand shower (not shown). It is a figure. FIG. 4 is a partially enlarged view of FIG.

As shown in FIG. 1, a valve shaft 4 is attached to the center of a circular knob 3 of the switching valve 2 so as to be vertically slidable. A start valve 5 is arranged at the lower end of the valve shaft 4, and a main valve 6 is provided coaxially with the start valve 5.
The start valve 5 is located in the start valve chamber 5A, and when the start valve chamber 5A is sealed by the main valve 6, water pressure is applied to the main valve 6 so that the valve shaft 4 is unlikely to move upward. On the other hand, when the knob 3 is slightly pulled up to form a gap between the main valve 6 and the starting valve chamber 5A, and water pressure is applied to the starting valve chamber 5A, the starting valve 5
Also, the main valve 6 receives the push-up force, and the operation force for pulling up the knob 3 is small.

The valve shaft 4 is inserted, and a valve opening 7 opened and closed by the main valve 6 as the valve shaft 4 moves in the vertical direction is opened in the partition wall 8. Therefore, knob 3
Is pushed down as shown in FIG. 1, the valve shaft 4 is lowered, and the valve port 7 is opened, the mixed hot water supplied from the mixing device (not shown) is discharged through the valve port 7 (not shown). Is discharged from. On the other hand, a lock groove 4A is formed on the outer peripheral surface of the valve shaft 4, and a plurality of spheres 9 that come into contact with the surface of the lock groove 4A are provided in a plurality of windows 10A of a cylindrical sphere support 10 (see FIG. 2). (See the enlarged section) It is loosely fitted so that it can roll. An O-ring 11 is fitted on the outer peripheral surface of the sphere support 10.

A slide lock member 12 is slidably arranged on the outer peripheral surface of the sphere support 10. When the slide lock member 12 receives the pressure of the mixed hot water or the like when the valve port 7 is opened, the slide lock member 12 is in accordance with the magnitude of the water pressure.
It is slid upward along the outer peripheral surface of 0. The shape of the inner diameter surface of the slide lock member 12 is such that the lower inner diameter is smaller than the upper inner diameter as shown in FIG.
When 2 is slid upward under the water pressure of the mixed hot water or the like and the magnitude of the water pressure exceeds a predetermined value, the small inner diameter portion abuts on the sphere 9 so that the sphere 9 is brought into contact with the lock groove 4A surface. Press on. As a result, the movement of the valve shaft 4 is locked and the valve shaft 4 is prevented from being pulled upward.

A spring 13 is arranged outside the valve shaft 4 and is elastically mounted between the upper end surface of the slide lock member 12 and the ceiling surface of the inside of the faucet 1 to form the slide lock member 12
Is urged downward. Therefore, this spring 13
By adjusting the elastic force of the slide lock member 12 or by adjusting the weight of the slide lock member 12, the slide amount when the slide lock member 12 is slid upward under the water pressure of the mixed hot water or the like is adjusted. Therefore, the water pressure for locking the valve shaft 4 can be arbitrarily set.

Next, as shown in FIG. 1, the valve shaft 4 is locked by the slide lock member 12 and the hot water is discharged from the discharge port of the water discharge tap 1 by adjusting a mixer (not shown). When the water pressure of the mixed hot water or the like drops below a predetermined value, the valve shaft 4 is unlocked, and the knob 3 can be pulled up. That is, it is possible to eject hot water from the hand shower. In Figure 3, the knob 3 is pulled up,
It shows a state in which the valve shaft 4 is slid upward.

As shown in FIGS. 3 and 4, when the knob 3 is pulled up and the valve shaft 4 is slid upward, the valve port 7 is closed by the main valve 6. Therefore, the mixed hot water discharged from the discharge port of the water discharge tap 1 is stopped and sprayed from a hand shower (not shown). Since the water pressure on the slide lock member 12 becomes zero, the slide lock member 12 descends to the O-ring 11. Further, the ball 9 comes out of the lock groove 4A and comes into contact with the large inner diameter portion of the slide lock member 12, and the lock groove 4A is exposed to the upper portion of the water spout 1.

As described above, the slide lock member 12
When subjected to the pressure of the mixed hot water when the valve port 7 is open, the slides along the outer peripheral surface of the sphere support 10 according to the magnitude of the pressure. When the water pressure of the mixed hot water is higher than a predetermined value, the slide lock member 12 pushes the ball 9 and pushes it against the lock groove 4A to lock the sliding of the valve shaft 4. On the other hand, when the water pressure of the mixed hot water is lower than the predetermined value,
Since the slide lock member 12 descends and the pressing force on the ball 9 decreases, the valve shaft 4 can slide. In this way, when the water pressure of the mixed hot water is lower than the predetermined value, the valve shaft 4 can be slid, so that the knob 3 can be pulled up and switched to the hand shower. And because the water pressure on the hand shower is low, the shower
The hose is suppressed from dancing.

[0021]

As described above, according to the present invention, when the valve shaft is operated upward, the water from the water supply source is hand-washed.
In the faucet equipped with a switching valve that ejects water from the water source from the discharge port when the valve shaft is operated downward, a pressing member that is pressed against the valve shaft and the outside of the pressing member. A slide that locks the valve shaft by sliding in a direction parallel to the valve shaft according to the pressure of the water when the water is being discharged from the water discharge port and pressing the pressing member toward the valve shaft side. Since the lock member is provided, when the water pressure applied to the faucet is higher than a predetermined value, the switching valve is prevented from being switched to the hand shower side, and when the water pressure is lower than the predetermined value, it is switched to the hand shower side. Therefore, it is possible to prevent the shower hose of the hand shower from violently moving due to high water pressure. Further, since the spring that has been inserted through the valve port in the conventional water discharge plug is not required, the water discharge valve of the present invention has an effect that the area of the valve port can be increased.
