Description

  Aspects of the present invention generally relate to a sanitary washing device, and more particularly to a sanitary washing device that is attached to a toilet and has a function of washing the body with wash water.

When the sanitary washing device is attached to the toilet bowl or removed from the toilet bowl, the electrical wiring is also attached and detached together with the attachment and detachment of the water supply pipe.
In many sanitary washing apparatuses, water supply pipes and electric wiring are arranged behind the toilet seat. For this reason, the operator must perform the detachment work in a narrow place where entry is difficult. In addition, there is room for improvement in terms of workability because work near the floor is forced.

  In Patent Document 1, from the viewpoint of improving the workability of attaching and detaching the sanitary washing device, a sanitary structure in which a connecting portion for water supply is installed on the upper surface of the toilet seat mounting surface or the rear side vertical surface so that the water supply pipe can be easily removed. A cleaning device has been proposed. In this structure, since the water stop valve operates simultaneously with the attachment and removal of the water supply pipe, the water supply pipe can be easily attached and removed.

  However, in the structure disclosed in Patent Document 1, since the water stop valve operates simultaneously with the installation and removal of the water supply pipe, the work must be performed with the water pressure applied. For this reason, it is necessary to increase the operation force at the time of attachment and detachment of the water supply pipe to the water supply connection part. Further, depending on the timing at which the water stop valve closes when the water supply pipe is attached to or removed from the water supply connection portion, some water leakage may occur. In order to avoid this, it is necessary to close the main plug of the water supply source before the attaching / detaching operation, which increases the labor of the operation.

For this reason, the control power PW2 is not supplied to the electromagnetic valve 650, and it remains in the closed state.

  Furthermore, by bringing the sanitary washing main body portion 100 closer to the water supply connection portion 600, the electrode terminal 160A and the electrode terminal 160B of the power supply portion 160 are in contact with each other as shown in FIG. Thus, the control power PW2 passes through the power supply unit 160 and is supplied to the electromagnetic valve 650. The electromagnetic valve 650 is opened by the supply of the control power PW2. Here, the electromagnetic valve 650 is opened after the supply pipe P1 is inserted into the connection hole 610, that is, the supply pipe P1 is inserted behind the position of the sealing material 610a in the connection hole 610. Later. Therefore, at the stage where the electromagnetic valve 650 is opened and the flow of the cleaning water is started, the sealing between the supply pipe P1 and the connection hole 610 is already secured, and there is no fear of water leakage.

  Thus, in the attachment of the sanitary washing main body 100, even when the washing water is still supplied from the water supply source 20 to the water supply connection portion 600 (for example, the water supply is not stopped by the water stop valve 21), Since water pressure is not applied when the supply pipe P1 is inserted into the connection hole 610, the supply pipe P1 can be easily inserted. Therefore, the attachment work of the sanitary washing main body 100 can be performed very easily.

  When the contact and non-contact between the electrode terminal 160A and the electrode terminal 160B are switched, it is desirable that the supply pipe P1 is inserted as deep as possible into the connection hole 610. For example, the sanitary washing main body 100 may be mounted on the base plate 700 and slid rearward so that the electrode terminal 160A and the electrode terminal 160B are brought into contact with each other slightly before reaching the fixed position. Thereby, switching of opening and closing of the electromagnetic valve 650 is performed in a state where the supply pipe P1 is firmly inserted into the connection hole 610, and water leakage at the time of attaching and removing the supply pipe P1 is effectively suppressed. It will be possible.

  In the present embodiment, it is possible to easily conduct and block the water supply to the supply pipe P1 only by attaching and detaching the sanitary washing main body 100 to the toilet bowl 800. Therefore, the workability is greatly improved by the operator.

(Second Embodiment)
Next, an example of a sanitary washing device according to the second embodiment will be described.
FIG. 8 is a block diagram illustrating the main configuration of the sanitary washing device according to the second embodiment.
In FIG. 8, the water channel system is indicated by white arrows, and the electrical system is indicated by black arrows.
The sanitary washing device 110A according to the second embodiment has the same water channel system as the sanitary washing device 110 according to the first embodiment, but is different in electrical system.

  That is, as illustrated in FIG. 8, in the sanitary washing device 110 </ b> A, the power PW is directly supplied from the power supply unit 500 to the water supply connection unit 600. The control power PW2 sent to the electromagnetic valve 650 is the same as the power PW of the external power supply 30. The electric power sent from the external power supply 30 is branched in the water supply connection unit 600, passes through the power supply unit 161, and is sent to the power supply circuit 510 provided in the sanitary washing main body unit 100.

  The control power PW2 sent from the power feeding unit 500 is intermittently switched by the switch SW1. That is, when the switch SW1 is closed, the control power PW2 sent from the power feeding unit 500 is supplied to the electromagnetic valve 650. On the other hand, when the switch SW1 is opened, the control power PW2 is not supplied to the electromagnetic valve 650.

The switch SW1 is attached to the water supply connection portion 600, for example. The switch SW1 is closed when the sanitary washing main body 100 approaches the water supply connection 600. The switch SW1 is opened when the sanitary washing main body 100 is separated from the water supply connection portion 600.
FIG. 9 is a block diagram illustrating another specific example of the main configuration of the sanitary washing device according to the second embodiment.
In this specific example, the power supply circuit 510 is provided separately from the sanitary washing main body 100. Then, the control power PW2 is supplied to the electromagnetic valve 650 through the power supply circuit 510, and the power PW1 passes through the power supply unit 161 and is supplied to the control unit 1000 provided in the sanitary washing main body unit 100.
In the specific example shown in FIG. 9, the power supply circuit 510 is separated from the water supply connection portion 600, but the present invention is not limited to this. That is, the power supply circuit 510 may be provided in the water supply connection unit 600.

Next, connection and release operations of the supply pipe P1 and the power supply unit 161 accompanying the attachment and detachment of the sanitary washing main body 100 will be described.
FIG. 10 is a schematic view illustrating a state in which the sanitary washing main body is removed.
FIG. 11 is a schematic view illustrating a state where the sanitary washing main body is attached.

First, the operation | movement at the time of removing the sanitary washing main-body part 100 is demonstrated.
As shown in FIG. 10A, in a state where the sanitary washing main body 100 is attached to the toilet bowl 800, the supply pipe P <b> 1 of the sanitary washing main body 100 is inserted into the connection hole 610 of the water supply connection 600. Further, the switch SW1 is pushed by the protrusion 101 of the sanitary washing main body 100, and is in a closed state. As a result, the control power PW2 is supplied from the power supply unit 500 or the power supply circuit 510 to the electromagnetic valve 650, and the electromagnetic valve 650 is opened. Therefore, the cleaning water sent from the water supply source 20 to the water supply connection part 600 via the water supply pipe P2 passes through the electromagnetic valve 650 and is sent from the supply pipe P1 to the sanitary washing main body part 100.

  Further, in a state where the sanitary washing main body 100 is attached to the toilet bowl 800, the electrode terminals 161A and 161B of the power supply unit 161 are in contact with each other, and the power PW supplied from the power supply unit 500 or the power supplied from the power supply circuit 510 is used. PW1 passes through the power supply unit 161 and is sent to the sanitary washing main body unit 100.

  As shown in FIG. 10B, when the sanitary washing main body 100 is pulled away from the water supply connection portion 600, the protrusion 101 of the sanitary washing main body 100 that has pressed the switch SW1 is released, and the switch SW1 is closed. As a result, the control power PW2 supplied to the electromagnetic valve 650 is cut off, and the electromagnetic valve 650 is closed.

At this time, the electrode terminals 161A and 161B of the power supply unit 161 are still in contact with each other. At this stage, the supply pipe P1 is inserted deeper than the position of the sealing material 610a in the connection hole 610. That is, before the supply pipe P1 is removed from the connection hole 610, the supply of the control power PW2 to the electromagnetic valve 650 is surely cut off, and the electromagnetic valve 650 can be closed.
When the electromagnetic valve 650 is closed, the wash water sent from the water supply source 20 is blocked by the electromagnetic valve 650 and is not passed through the supply pipe P1.

  Subsequently, when the sanitary washing main body 100 is further pulled away from the water supply connection portion 600, the supply pipe P1 is pulled out from the connection hole 610 of the water supply connection portion 600 as shown in FIG. In this state, water pressure is not already applied to the supply pipe P1, and it can be easily pulled out. In addition, the contact between the electrode terminal 161A and the electrode terminal 161B of the power supply unit 161 is released. Thereby, the electric power PW or PW1 supplied to the sanitary washing main body 100 is surely cut off.

Thus, in the removal of the sanitary washing main body 100, even when the washing water is still supplied from the water supply source 20 to the water supply connection portion 600 (for example, the state where the water supply is not stopped by the water stop valve 21), The supply pipe P1 can be easily pulled out from the connection hole 610. Therefore, the removal operation of the sanitary washing main body 100 can be performed very easily.
Further, by removing the sanitary washing main body 100, the electric wiring between the external power source 30 and the power feeding unit 500 and the sanitary washing main body 100 is also separated. Thereby, it becomes possible to isolate | separate both a waterway system and an electrical system, and to remove only the sanitary washing main-body part 100 from the toilet bowl 800 in a free state.

Next, the operation | movement at the time of attaching the sanitary washing main-body part 100 is demonstrated.
As shown in FIG. 11A, in the state where the sanitary washing main body 100 and the water supply connection portion 600 are completely separated from each other, the switch SW1 is in an open state. For this reason, the control power PW2 is not supplied to the electromagnetic valve 650, and the electromagnetic valve 650 is closed. Therefore, even if cleaning water is sent from the water supply source 20 to the water supply connection portion 600, it is blocked by the electromagnetic valve 650.

  Next, as shown in FIG. 11B, the sanitary washing main body 100 is brought close to the water supply connection portion 600 and the supply pipe P <b> 1 is inserted into the connection hole 610 of the water supply connection portion 600. Here, in a state in which the supply pipe P1 is inserted slightly deeper than the position of the sealing material 610a in the connection hole 610, the switch SW1 is not pushed by the protrusion 101 and remains open. For this reason, the control power PW2 is not supplied to the electromagnetic valve 650, and it remains in the closed state.

  On the other hand, the electrode terminal 161A and the electrode terminal 161B of the power supply unit 161 are in contact with each other. As a result, the power PW supplied from the power supply unit 500 or the power PW1 supplied from the power supply circuit 510 passes through the power supply unit 161 and is sent to the sanitary washing main body unit 100.

  Furthermore, only when the sanitary washing main body 100 is brought closer to the water supply connection portion 600, as shown in FIG. 11C, the protrusion 101 of the sanitary washing main body 100 pushes the switch SW1, that is, the switch SW1 is closed. . As a result, the control power PW2 is supplied from the power supply unit 500 or the power supply circuit 510 to the electromagnetic valve 650. The electromagnetic valve 650 is opened by the supply of the control power PW2. Here, the electromagnetic valve 650 is opened after the supply pipe P1 is inserted into the connection hole 610, that is, the supply pipe P1 is inserted behind the position of the sealing material 610a in the connection hole 610. Later. Therefore, at the stage where the electromagnetic valve 650 is opened and the water flow of the cleaning water 50 is started, the sealing property between the supply pipe P1 and the connection hole 610 is already secured, and there is no fear of water leakage. .

  Thus, in the attachment of the sanitary washing main body 100, even when the washing water is still supplied from the water supply source 20 to the water supply connection portion 600 (for example, the water supply is not stopped by the water stop valve 21), Since water pressure is not applied when the supply pipe P1 is inserted into the connection hole 610, the supply pipe P1 can be easily inserted. Therefore, the attachment work of the sanitary washing main body 100 can be performed very easily.

  In the present embodiment, it is possible to easily conduct and block the water supply to the supply pipe P1 only by attaching and detaching the sanitary washing main body 100 to the toilet bowl 800. In addition, when the sanitary washing main body 100 is removed from the toilet bowl 800, since the electrical system wiring is separated in addition to the water channel system, the sanitary washing main body 100 can be detached independently without dragging the electrical wiring. The workability is greatly improved by the operator.

  In the sanitary washing apparatus 110A described above, the switch SW1 does not necessarily have to be attached to the water supply connection portion 600. That is, any position may be used as long as the electromagnetic valve 650 can be switched between open and closed in accordance with the timing of attachment and removal of the supply pipe P1 to and from the connection hole 610 as described above.

FIG. 12 is a schematic perspective view for explaining another example of the water supply connection portion.
In the water supply connection portion 600A shown in FIG. 12A, the positions of the power supply portions 160 and 161 are arranged above the position of the connection hole 610.

  When the supply pipe P1 is removed from the connection hole 610 of the water supply connection part 600A, there is a possibility that the cleaning water slightly remaining in the supply pipe P1 hangs down. In the water supply connection portion 600A, since the power supply portions 160 and 161 are above the position of the connection hole 610, it is possible to prevent the power supply portions 160 and 161 from being applied even if the cleaning water drips from the vicinity of the connection hole 610. . Thereby, the flooding to the electric power supply part at the time of removing supply piping P1 can be prevented.

In the water supply connection portion 600 </ b> B shown in FIG. 12B, a groove 630 is provided between the connection hole 610 and the power supply portions 160 and 161. The presence of the groove 630 allows moisture adhering to the exterior of the water supply connection portion 600B to enter the groove 630 and suppress water exposure to the power supply portions 160 and 161.
In addition, in the water supply connection part 600B, you may provide a convex part (wall) instead of the groove | channel 630. FIG. By this convex part, it is possible to prevent moisture adhering to the exterior of the water supply connection part 600B from being transmitted from the connection hole 610 side to the power supply parts 160 and 161 side.

13 and 14 are schematic perspective views illustrating examples of application of the sanitary washing device to other toilet devices.
In FIG. 13, the state which attached the sanitary washing apparatus 110 and 110A which concern on embodiment to the toilet bowl 800 is shown.
In FIG. 14, the state which removed the sanitary washing apparatus 110 and 110A which concern on embodiment from the toilet bowl 800 is shown.

As shown in FIG. 13, in this toilet apparatus, the low tank 10 is disposed obliquely above and behind the toilet bowl 800. A cover 11 is provided between the side surface 10 b of the low tank 10 and the side surface 800 b of the toilet bowl 800. Inside the cover 11, a water supply pipe P2 is accommodated. The water supply pipe P <b> 2 is connected to the upstream side of the water supply connection portion 600 inside the cover 11.
In a state where the sanitary washing devices 110 and 110 </ b> A are attached to the toilet bowl 800, the supply pipe P <b> 1 is connected to the connection hole 610 on the downstream side of the water supply connection part 600.

  As shown in FIG. 14, when the sanitary washing devices 110 and 110 </ b> A are removed from the toilet bowl 800, the supply pipe P <b> 1 is removed from the connection hole 610 of the water supply connection part 600. When removing the sanitary washing devices 110 and 110A, the supply of the control power PW2 to the electromagnetic valve 650 is stopped and the electromagnetic valve 650 is closed before the supply pipe P1 is removed from the connection hole 610. . Therefore, the supply pipe P1 can be easily removed from the connection hole 610 in a state where water pressure is not applied to the supply pipe P1.

  Since the sanitary washing apparatuses 110 and 110A are connected to the water supply connection portion 600 by the supply pipe P1, no hose remains on the toilet seat 200 side when the sanitary washing apparatuses 110 and 110A are removed. In the toilet apparatus shown in FIGS. 13 and 14, the water supply pipe P2 is housed inside the cover 11, so that the hoses are not exposed to the outside with the sanitary washing apparatuses 110 and 110A removed. That is, when the sanitary washing devices 110 and 110A according to the embodiment are applied to the toilet device, the appearance when the sanitary washing devices 110 and 110A are removed is good, and the cleanability is very excellent.

  As described above, according to the sanitary washing devices 110 and 110A according to the embodiment, the supply pipe P1 can be easily attached and detached even when the washing water is supplied from the water supply source 20, and the supply is performed. It becomes possible to suppress water leakage during the installation and removal of the pipe P1.

  In the above-described embodiment, the structure in which the sanitary washing main body 100 can be attached and removed by sliding in the front-rear direction of the toilet bowl 800 has been described, but the present invention is not limited to this.
