BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filth washing faucet that can discharge water into the toilet from above the toilet and can wash filth in the toilet.
[0002]
[Prior art]
This kind of filth washing faucet is mainly installed in a toilet in a hospital, particularly in a hospital room.
For example, there is an increasing demand for washing a urine bottle in a toilet, and in order to meet this demand, in recent years, this kind of filth washing faucet has been installed in a toilet in a hospital room.
[0003]
FIG. 8 shows an example.
In the figure, 200 is a toilet installed in the toilet, 202 is a toilet body, and 204 is a toilet seat.
W is a wall on the rear side of the toilet 200, and a filth washing faucet 206 is installed on the wall W.
[0004]
The filth water faucet 206 includes a faucet body 208, a water discharge pipe 210 extending therefrom, and a handle 212.
The water discharge pipe 210 has a horizontal part 210A that is substantially horizontal and a bent part 210B that is bent from the horizontal part 210A. The water discharge pipe 210 is generally L-shaped as a whole, and is attached to the wall W at the horizontal part 210A. The support member 216 is supported so as to be pivotable up and down.
[0005]
In the water discharge pipe 210, the horizontal portion 210A can rotate around its own axis between the use position shown in FIG. 9 (II) and the retracted position shown in (I), and the bent portion 210B rotates around its axis. It is possible to move.
Specifically, as shown in FIG. 9 (II), the water discharge pipe 210 has a use position in which the bent portion 210B extends to the upper side of the toilet bowl 200 and the water discharge port 214 at the distal end faces the inside of the toilet bowl 200, and (I) As shown in FIG. 4, the bent portion 210B is rotatable between a retracted position where the bent portion 210B is retracted from the upper side of the toilet bowl 200 to a standing state.
[0006]
In the case of the filth washing faucet 206, water can be discharged into the toilet bowl 200 with the water discharge pipe 210 lowered to the use position shown in FIG. 9 (II). It can be performed.
On the other hand, when using the toilet bowl 200, the water discharge pipe 210 is raised to the retracted position in FIG.
[0007]
By the way, in the case of the filth washing faucet 206, if the handle 212 is accidentally opened while the water discharge pipe 210 is in the retracted position shown in FIG. 9I, the water discharge port 214 is in a horizontal or substantially upward state. Water is discharged from the user and water is applied to the user who is seated on the toilet 200, or even when there is no person on the toilet 200, the water from the outlet 214 around the toilet 200 There is a risk of scattering.
[0008]
Therefore, in the case of the filth washing faucet 206 shown in FIGS. 8 and 9, measures are taken so that the handle 212 cannot be opened under the condition that the water discharge pipe 210 is in the retracted position.
Specifically, in this filth washing faucet 206, an arm 224 is provided so as to rotate integrally with the water discharge pipe 210, and a pair of protruding knobs 218 of the handle 212 in the water stop operation position is provided on the arm 224. A stopper 220 is provided at both ends of the curved portion 222 so as to abut against the rotation portion and prevent rotation in the opening direction.
[0009]
Therefore, in this filth washing faucet 206, when the water discharge pipe 210 is in the retracted position, the handle 212 cannot be opened, so that water from the water outlet 214 falls on the user or is scattered around the toilet bowl 200. Can be effectively prevented.
[0010]
[Problems to be solved by the invention]
However, the filth washing faucet 206 still has the following problems.
That is, the filth washing faucet 206 is in a state where water discharge is performed at the use position shown in FIG. 9 (II), although the water discharge operation cannot be performed when the water discharge pipe 210 is in the retracted state shown in FIG. 9 (I). Thus, the water discharge pipe 210 can be turned upward toward the retracted position. Therefore, if the water discharge pipe 210 is accidentally turned upward in the water discharge state, the water from the water discharge outlet 214 is discharged from the toilet bowl. The problem of scattering outside the 200 is inherent.

【Example】
Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a toilet installed in a toilet in a hospital room, 12 is a toilet body, 14 is a toilet seat, and W is a rear wall of the toilet 10. On the wall W, the filth washing faucet 16 of this example is installed.
[0029]
The filth washing faucet 16 includes a faucet body 18, a handle 20 for discharging and stopping water, and a water discharge pipe 22 extending from the faucet body 18.
The water discharge pipe 22 has an L-shape as a whole having a horizontal portion 22A that is substantially horizontal and a bent portion 22B that is bent thereby, and the horizontal portion 22A is vertically moved by a support member 24 attached to the wall W. It is rotatably supported.
[0030]
As shown in FIG. 2C, the water discharge pipe 22 has a bent portion 22 </ b> B extending almost horizontally to the upper side of the toilet 10, and a use position where the water discharge port 26 at the distal end faces the inside of the toilet 10. From S ₁ , it is possible to turn up and down between a retreat position S ₃ that stands up and retreats from above the toilet 10 to the wall W side.
[0031]
In this example, when water is discharged within a range of 20 ° (position of S ₂ ) at least upward from the use position S ₁ at which the bent portion 22B is substantially horizontal, the water discharged falls into the toilet bowl 10.
That is, as long as water is discharged within this range, water discharged from the water outlet 26 does not scatter outside the toilet 10.
[0032]
The handle 20 is a rotary operation type handle, and is provided with a long lever 28 protruding in the direction perpendicular to the rotation axis, a knob 32 and a safety button 30 for assisting the rotation operation.
The handle 20 can be rotated in the opening direction for the first time by pressing the safety button 30.
[0033]
As shown in detail in FIG. 2, an arm 34 having a substantially L shape is provided at the base of the water discharge pipe 22 so as to rotate integrally therewith.
The arm 34 has a first part 34A that protrudes in a direction perpendicular to the axis of the horizontal part 22A in the water discharge pipe 22, and a second part 34B that is bent substantially horizontally from the tip thereof. The front end in FIG. 2A of 34B is configured as a first stopper 36.
[0034]
As shown in FIGS. 2B and 2C, the first stopper 36 is brought into contact with the rear end of the lever 28 when the lever 28 of the handle 20 is vertically downward (opening operation position). contact acts to prevent upward rotation of the water discharge pipe 22, i.e., the rotation towards the retracted position S _3.
[0035]
Here, the lever 28 is in a state where the vertically downward position in FIG. 2B is in the fully open position, that is, the movable opening 46 is completely aligned with the fixed opening 44 of the valve portion 42 (see FIG. 3) in the faucet body 18. It becomes.
Thus, the handle 20 rotates the movable opening 46 of the valve portion 42 together by rotating the lever 28 counterclockwise from this position, and gradually reduces the area of the overlapping portion of the movable opening 46 and the fixed opening 44. . That is, the water discharge flow rate from the water discharge port 26 is gradually reduced.
[0036]
2B, when it is rotated 45 ° to the left as shown by a two-dot chain line in the figure from the fully open position, the overlapping portion of the movable opening 46 and the fixed opening 44 disappears, The water discharge from the water discharge port 26 is stopped and the water is stopped.
[0037]
The lever 28 can be further rotated from this 45 ° tilted position to a horizontal position indicated by a two-dot chain line in FIG. However, the water stoppage is maintained within this range.
That is, as shown in FIGS. 3A, 3I, and II, within this range, the fixed opening 44 and the movable opening 46 are in a completely inconsistent state, and in this state (I), the lever 28 rotates. Even so, the water discharged from the water outlet 26 is kept in a stopped state, that is, in a water-stopped state.
[0038]
A second stopper 40 protrudes from the tip of the second portion 34B of the arm 34.
The second stopper 40 when in the FIG. 1 and FIG. 4 retreated position S ₃ and the water discharge pipe 22 is in an upward raised condition when the lever 28 as shown in (I) is in a horizontal position, the lever 28 By contacting the lower surface, the lever 28, that is, the handle 20 is prevented from rotating in the opening direction.
[0039]
In FIG. 2B, the upper surface of the second portion 34B and the inner surface of the second stopper 40 are configured as guide surfaces 38A and 38B for rotating the lever 28 in the closing direction, respectively.
In this example, these guide surfaces 38A 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), the side of the use position indicated by S ₁ of the water discharge pipe 22 in FIG. 2 (C) When the rotation operation is erroneously performed upward, the lever 28 is forcibly rotated to the left by the guide action with the upward rotation of the water discharge pipe 22, that is, with the upward rotation of the arm 34.
[0041]
Then, when the lever 28 is rotated to some extent, the guide surface 38B of the second stopper 40 subsequently hits the lever 28, and the lever 28 is subsequently moved to the position shown in FIG. It is forcibly rotated by the guide action to the horizontal position indicated by the middle two-dot chain line.
[0042]
Next, the operation of the filth washing faucet 16 of this example will be described in detail with reference to FIGS.
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. Therefore, in this state, the handle 20 cannot be rotated in the opening direction. That is, in this state, there is no possibility that the handle 20 is erroneously rotated and discharged from the water outlet 26.
[0043]
Is rotated downwardly water discharge pipe 22 to the use position S ₁ as shown in FIG. 4 (II) from this state, the arm 34 is rotary motion integrally with the downward and rearward along with this, whereby The rotation blocking action on the lever 28 by the second stopper 40 is released.
[0044]
Here, the handle 20 can be rotated in the opening direction, and water can be discharged from the water outlet 26 of the water discharge pipe 22.
Therefore, in this state, it is possible to wash filth such as urine bottles inside the toilet 10 without any trouble.
[0045]
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 in the vertically downward state, so that the lever 28 is vertically downwardly directed. The spout tube 22 will not be accidentally rotated upward in this state.
[0046]
In this example, when the water discharge pipe 22 is turned upward at a position where the lever 28 is rotated slightly to the left from the completely vertical downward posture, the lever 28 is interlocked and moved to the left by the guide surface 38A. It is forcibly rotated.
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. 5 (II). The guide surface 38A first hits the lower end of the lever 28, and the lever 28 is pushed leftward as the water discharge pipe 22 continues to rotate upward, thereby rotating it.
[0047]
Then, as shown in FIG. 6 (III), when the lever 28 is rotated to the left to a certain angle, the guide surface 38B of the second stopper 40 then comes into contact with the lever 28, and then With the further upward rotation of the water discharge pipe 22, this guide surface 38B now forcibly rotates the lever 28 to the left (see FIGS. 6 (IV) and 7 (V)).
Then, as shown in FIG. 7 (VI), when the water discharge pipe 22 is rotated upward to the standing posture (retracted position S ₃ ), the lever 28 is in a completely horizontal water stop state, and FIG. Return to the initial state shown in.
[0048]
The second stopper 40 As is apparent from this description, within the downward a predetermined angle range water discharge pipe 22 from a fully retracted position S _3, to prevent rotation of the opening operation position of the lever 28, i.e. the handle 20 You can think of it as a stopper.
That is, it can be considered that the water discharge pipe 22 functions as a stopper that prevents the opening operation of the handle 20 in an angle range in which water is discharged to the outside of the toilet 10.
[0049]
In the filth washing faucet 16 of this example as described above, by providing the first stopper 36, the water discharge pipe 22 is accidentally turned upward while water is discharged from the water discharge pipe 22 toward the toilet bowl 10. Therefore, the inconvenience that the water from the water discharge pipe 22 is scattered outside the toilet bowl 10 can be eliminated.
[0050]
The first stopper 36 hits the lever 28 of the handle 20 in the open operation position to prevent the water discharge pipe 22 from rotating. Therefore, when the handle 20 is in the open operation position, the first stopper 36 reliably while capable of preventing an upward rotation, the handle 20 can be pivoted to the retracted position S ₃ without hindrance water discharge pipe 22 when in a closing operation position.
[0051]
In the present embodiment, within the rotation range of the water discharge pipe 22 from the side of the use position S ₁ until the water discharge and outside the toilet 10 with the upward rotation toward the side of the retracted position S _3, open operating position upwardly times toward the handle 20 for rotating operation in conjunction to the water stopping operation position, the retracted position S ₃ incorrectly water discharge pipe 22 in the water discharge state in which the lever 28 is slightly inclined to the left from the vertical downward at the Even if the operation is performed, it is possible to prevent the water from the spout 26 from being scattered outside the toilet bowl 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, the outer water befell or or toilet bowl 10 to the user of the toilet 10 Water can be prevented from splashing. That is, in any case where water discharge should not be performed, the water discharge from the water discharge pipe 22 can be reliably prohibited.
[0053]
Further, in this example, since the handle 20 is configured to maintain the water stop operation state over a predetermined rotation range, the guide surfaces 38A and 38B and the second stopper portion 40 can be easily configured on the arm 34. Can do.
[0054]
Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be configured in various modifications without departing from the spirit of the present invention.
