In the case of this filth washing faucet 206, the spout 2
In a state where the toilet 10 is tilted to the use position in FIG.
The water can be spouted in the inside of the toilet 0, so that the used urine and the like can be washed in the toilet 200. When the toilet 200 is used, the water discharge pipe 210 is
When the user is raised upward to the retreat position (I), the user can sit on the toilet 200.

In the case of the waste water faucet 206,
If the handle 212 is erroneously opened while the water discharge pipe 210 is in the retracted position shown in FIG. 9 (I), water is discharged from the water discharge port 214 which is in a horizontal or almost upward state, and the toilet 200 is discharged. There is a risk that water may be applied to the seated user, or that water from the spout 214 may be scattered around the toilet 200 even when there is no person on the toilet 200.

Therefore, in the case of the waste water faucet 206 shown in FIGS. 8 and 9, measures are taken to prevent the handle 212 from being opened when the water discharge pipe 210 is in the retracted position.

Stoppers 220 are provided at both ends of the curved portion 222 to abut against the opening and prevent rotation in the opening direction.

Therefore, when the water discharge pipe 210 is located at the retracted position, the handle 2
Since the opening operation of 12 cannot be performed, it is possible to effectively prevent the water from the spout 214 from falling on the user or scattering around the toilet 200.

[0010]

However, the wastewater faucet 206 still has the following problems. That is, the waste water faucet 206 cannot perform the water discharge operation when the water discharge pipe 210 is in the retracted state shown in FIG. 9 (I), but is performing the water discharge at the use position shown in FIG. 9 (II). From the spout 21
0 can be turned upward toward the evacuation position. Therefore, if the water discharge pipe 210 is erroneously turned upward in the water discharge state, water from the water discharge port 214 is discharged from the toilet 2.
There is an inherent problem of scattering outside of 00.

[0011]

According to an eighth aspect of the present invention, in any one of the first to sixth aspects, the handle is configured to maintain a water stopping operation state over a predetermined rotation range.

[0019]

As described above, according to the first aspect of the present invention, the water discharge pipe pivots upward from the use position to the retracted position until the water discharge pipe discharges water out of the toilet while the handle is in the open operation position. In this filth washing faucet, the water spouting pipe is erroneously turned upward while spouting water from the spouting pipe to the toilet bowl. The inconvenience that water from the water scatters outside the toilet can be eliminated.

Here, the first stopper is not limited to the one in which the water discharge pipe is always stopped at the lower end of rotation, that is, the use position.
Further, just before reaching the position where the water discharge pipe discharges water out of the toilet, further upward rotation can be prevented. Preferably, however, the first stopper is configured so that the water discharge pipe is stopped at the use position (claim 2). In this way, it is possible to reliably prevent the water from the water discharge pipe from scattering outside the toilet.

In this case, an arm which rotates integrally with the water discharge pipe is provided, and the arm is provided with a first stopper which abuts on a lever of a handle located at an open operation position to prevent the rotation of the water discharge pipe. (Claim 3). With this configuration, the first stopper that prevents the water discharge pipe from rotating upward can be easily configured.

This first stopper prevents the rotation of the water discharge pipe by hitting the lever of the handle in the open operation position, so that the upward movement of the water discharge pipe is ensured when the handle is in the open operation position. While the rotation can be prevented, the water discharge pipe can be rotated to the retreat position without any trouble when the handle is in the closing operation position.

In the fourth aspect, the opening operation is performed with the upward rotation of the water discharge pipe from the use position side to the retracted position side and within the rotation range until water is discharged out of the toilet. A guide part that rotates the handle in the position to the water stop operation position in conjunction with the water stop operation position is provided. Even in such a case, the water discharge pipe in the use state, i.e., the water discharge state is erroneously turned to the evacuation position. Even if the water is turned upward, the water from the spout can be prevented from scattering outside the toilet.

In this case, the guide portion may be provided with an arm which rotates integrally with the water discharge pipe, and may be provided on the arm. At this time, the guide portion can be configured to convert the rotational movement of the water discharge pipe into rotation in the closing direction of the handle by hitting a lever of the handle in the open operation position (claim 5). With this configuration, the guide section can be configured with a simple configuration, and the handle can be reliably rotated in the closing direction with the rotation of the water discharge pipe.

In the present invention, a second stopper for preventing the handle from rotating in the opening direction when the water discharge pipe is at the retracted position can be provided. By doing so, it is possible to prevent the water from being discharged from the water discharge pipe at the evacuation position and the water from falling to the user of the toilet bowl, or the water from splashing out of the toilet bowl. That is, in any case where water should not be discharged,
Water discharge from the water discharge pipe can be reliably prohibited.

In this case, an arm which rotates integrally with the water discharge pipe may be provided, and the arm may be provided with the second stopper. At that time, the second stopper
The rotation of the handle in the opening direction can be prevented by hitting the lever of the handle in the closing operation position (claim 7).

In the present invention, the handle can be kept in a water-stopping operation state over a predetermined rotation range. If you do this,
For example, when the arm is provided so as to rotate integrally with the water discharge pipe, the guide portion and the second stopper portion can be easily formed on the arm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 denotes a toilet installed in a toilet in a hospital room, 12 denotes a toilet body, 14 denotes a toilet seat, and W denotes a toilet 1
0 is the rear wall. The waste water faucet 16 of this example is mounted on the wall W.
Is installed.

The waste water faucet 16 is provided with a faucet main body 18.
A handle 20 for discharging and stopping water, and a faucet body 18
And a water discharge pipe 22 extending from the water discharge pipe 22. Spout 22
Is generally L-shaped having a horizontal portion 22A that is substantially horizontal and a bent portion 22B bent therefrom. In the horizontal portion 22A, the support member 24 attached to the wall W can rotate up and down. It is supported by.

As shown in FIG. 2 (C), the water discharge pipe 22 has a bent portion 22B extending substantially horizontally to a position above the toilet 10 and a water discharge port 26 at a distal end thereof facing the inside of the toilet 10. From the use position S ₁ , the toilet 1
Evacuation position S ₃ in a state of evacuation toward the wall W from above 0
Is rotatable up and down.

It should be noted in this example, when performing water discharge in the range of at least upwardly 20 ° from the use position S ₁ to the bent portion 22B substantially horizontal (the position of the S _2), the water discharge is toilet 1
It falls inside 0. That is, as long as the water is discharged within this range, the water discharged from the water discharge port 26 does not scatter outside the toilet 10.

The handle 20 is a rotary operation type handle. The handle 20 is provided with a long lever 28 protruding at right angles from the rotation axis, a knob 32 for assisting the rotation operation, and a safety button 30. By pressing the safety button 30, the handle 20 can be rotated in the opening direction for the first time.

As shown in detail in FIG.
Is provided with an arm 34 which is substantially L-shaped so as to rotate integrally therewith. The arm 34 has a first portion 34A protruding at right angles from the axis of the horizontal portion 22A of the water discharge pipe 22 and a second portion 34B bent substantially horizontally from the tip thereof. FIG. 2 of 34B
(A) The middle front end is configured as a first stopper 36.

The first stopper 36 is connected to the first stopper 36 as shown in FIG.
As shown in (C), when the lever 28 of the handle 20 is vertically downward (opening position), it comes into contact with the rear end of the lever 28, and the water pipe 22 is turned upward, that is, the retracted position. It acts to prevent rotation towards S _3.

Here, the lever 28 is in the fully open position in the vertically downward position in FIG. 2B, that is, the movable opening 46 relative to the fixed opening 44 of the valve portion 42 (see FIG. 3) in the faucet body 18.
Are completely matched. Thus the handle 20
When the lever 28 rotates leftward in the drawing from this position, the movable opening 46 of the valve portion 42 is also rotated, and the area of the overlapping portion between the movable opening 46 and the fixed opening 44 is gradually reduced. That is, the flow rate of water discharged from the water discharge port 26 is gradually reduced.

Then, as shown by the two-dot chain line in FIG.
At the time of the rotation by 5 °, the overlapping portion between the movable opening 46 and the fixed opening 44 disappears, and the water discharge from the water discharge port 26 stops here, and the water stops.

The lever 28 can be further rotated from this 45 ° inclined position to a horizontal position indicated by a two-dot chain line in FIG. However, the water stop state is maintained within this range. That is, as shown in FIGS. 3 (A), (I) and (II), within this range, the fixed opening 44 and the movable opening 46 are completely inconsistent, and in this (I) state, the lever 28 rotates. Even so, the water discharge from the water discharge port 26 is kept in a stopped state, that is, a water stopped state.

At the tip of the second portion 34B of the arm 34, a second stopper 40 is provided so as to protrude. This second stopper 40 is shown in FIGS.
When the lever 28 as shown in (I) is the water discharge pipe 22 and when in the horizontal position in the retracted position S ₃ upward upright, the lever 28 by abutting the lower surface of the lever 28, i.e. the handle 20 Acts to prevent rotation in the opening direction.

In FIG. 2B, the upper surface of the second portion 34B and the inner surface of the second stopper 40 are provided with guide surfaces 38A and 38A for rotating the lever 28 in the closing direction, respectively.
8B. In this example, these guide surfaces 3
8A and 38B constitute the entire guide portion.

[0040] Here, the guide surface 38A, under a state where the lever 28 is rotated slightly leftward from the vertically downward position shown in FIG. 2 (B), using water discharge pipe 22 is indicated by S ₁ shown in FIG. 2 (C) If the robot is accidentally rotated upward from the side of the position,
With the upward rotation of the water discharge pipe 22, that is, the arm 3
With the upward rotation of the lever 4, the lever 28 is forcibly rotated leftward by the guide action.

Then, when the lever 28 has rotated to some extent, the guide surface 38B of the second stopper 40 subsequently contacts the lever 28, and with further upward rotation of the water discharge pipe 22, the lever 28 is subsequently moved to the position shown in FIG. (B) Forced rotation by the guide action to the horizontal position indicated by the two-dot chain line.

Next, the operation of the waste water faucet 16 of this embodiment will be described with reference to FIG.
This will be described in detail with reference to FIG. Figure 4 (I) is water spouting pipe 22 is in the retracted position S _3, also handle 20 fully closing operation position, specifically shows the state where the lever 28 is in a horizontal position. At this time, the second stopper 40 of the arm 34 is located immediately below the lever 28, so that the handle 20 cannot be rotated in the opening direction in this state. That is, in this state, it does not occur that the handle 20 is erroneously rotated and the water is spouted from the spout 26.

[0043] is rotated downward from this state until use position S ₁ of the water discharge pipe 22 as shown in FIG. 4 (II), the arm 34 is rotary motion integrally with the downward and rearward along with this Thus, the rotation preventing action of the second stopper 40 on the lever 28 is released.

Here, the handle 20 can be rotated in the opening direction, and water can be discharged from the water discharge port 26 of the water discharge pipe 22. Therefore, in this state, it is possible to wash filth such as a urinal inside the toilet 10 without any trouble.

At this time, as shown in FIG. 4 (II), the first stopper 36 of the arm 34 is in contact with the rear end of the lever 28 which is in a vertically downward state, and therefore, the lever 28 is moved vertically. It does not occur that the water discharge pipe 22 is erroneously rotated upward with the downward direction.

In the present embodiment, at a position where the lever 28 is slightly rotated leftward from the completely vertical downward position, the water discharge pipe 2
When the lever 2 is rotated upward, the lever 28 is interlocked with this and is forcibly rotated leftward by the guide surface 38A. That is, as shown in FIG. 5 (I), when the water discharge pipe 22 rotates upward with the lever 28 slightly turned to the left, the upper surface of the second portion 34B as shown in FIG. First, the guide surface 38A contacts the lower end of the lever 28, and pushes the lever 28 to the left with the subsequent upward rotation of the water discharge pipe 22, thereby rotating the same.

Then, as shown in FIG. 6 (III), when the lever 28 has been rotated leftward to a certain angle, the guide surface 38 of the second stopper 40 is subsequently provided.
B comes into contact with lever 28 and, with further upward rotation of spout 22, this guide surface 38.
B continuously forcibly rotates the lever 28 leftward (see FIGS. 6 (IV) and 7 (V)). And Fig. 7 (VI)
As shown in FIG. 4, when the water discharge pipe 22 is turned upward to the upright posture (the retreat position S ₃ ), the lever 28 is in a completely horizontal water stop state, and returns to the initial state shown in FIG. And return.

[0048] The second stopper 40 As is apparent from this description, the rotation of the water discharge pipe 22 from a fully retracted position S ₃ in a downward a predetermined angle range, the opening operation position of the lever 28, i.e. the handle 20 Can be thought of as acting as a stopper to prevent That is, in the angle range in which the water discharge pipe 22 discharges water to the outside of the toilet 10, it can be considered that the water discharge pipe 22 functions as a stopper for preventing the opening operation of the handle 20.

In the filth washing faucet 16 of the present embodiment as described above, the provision of the first stopper 36 erroneously causes the water discharge pipe 22 to face upward while water is being discharged from the water discharge pipe 22 toward the toilet 10. And the inconvenience that the water from the water discharge pipe 22 scatters outside the toilet 10 can be eliminated.

The first stopper 36 prevents the rotation of the water discharge pipe 22 by hitting the lever 28 of the handle 20 in the open operation position, so that when the handle 20 is in the open operation position, the first stopper 36 is reliably discharged. while capable of preventing an upward rotation of the water tube 22, the handle 20 can be pivoted to the retracted position S ₃ without hindrance water discharge pipe 22 when in a closing operation position.

In this example, the water discharge pipe 22 is located at the use position S _1.
Within the turning range from the side to perform the water discharge and outside the toilet 10 with the upward rotation toward the side of the retracted position S _3, in conjunction with the handle 20 in an open operating position to a water shut-off operation position to rotation operation, even if the lever 28 is accidentally rotating operation upwardly toward the water discharge pipe 22 to the retracted position S ₃ by mistake in the water discharge state of slightly inclined leftward from the vertical downward, from the spouting port 26 Can be prevented from being scattered outside the toilet 10.

[0052] since it is provided also a second stopper 40 in the present example, too long and made discharged from the water discharge pipe 22 at the retracted position S _3, or or water befell to the user of the toilet 10 Water can be prevented from scattering outside the toilet 10. That is, in any case where water should not be discharged, it is possible to surely prevent water discharge from the water discharge pipe 22.

In this embodiment, since the handle 20 maintains the water stopping operation state over a predetermined rotation range, the arm 34 can be easily connected to the guide surfaces 38A and 38B and the second stopper portion 40. Can be configured.

Although the embodiment of the present invention has been described in detail, this is merely an example, and the present invention can be configured in variously modified forms without departing from the gist thereof.
