Description

  TECHNICAL FIELD The present invention relates to a sanitary washing toilet seat device and a toilet device, and more specifically to a sanitary washing toilet seat device for washing a user's “butt” or the like seated on a Western-style sitting toilet with water and a toilet device equipped with the same.

  Since the sanitary washing toilet seat apparatus accommodates a washing nozzle for injecting washing water in its interior so as to be able to advance and retreat, a mainstream one is a type that is installed and used at the upper rear part of a seated toilet. And in order to move the cleaning nozzle forward and backward, and to provide a odor suction port in the sitting toilet bowl, the front of the main body case constituting the sanitary cleaning toilet seat device extends to the bowl side of the sitting toilet, and a part of the bowl opening is It is supposed to be closed.

However, when the main body case extends to the bowl side in this way, the back side and the like easily become dirty. On the other hand, in order to improve the cleaning property, for example, a structure in which the extending part of the main body case is detachable is disclosed (for example, Patent Documents 1 and 2). However, it is troublesome to remove the extended portion one by one during cleaning, and there is a problem that the extended portion is accidentally dropped into the water pool of the bowl when attaching or detaching.
Japanese Patent Publication No. 5-74656 JP-A-6-167041

  In order to solve such a problem, it is preferable that the main body case of the sanitary washing toilet seat apparatus is set backward so as not to cover the bowl of the sitting toilet. However, when the main body case is moved backward, it is necessary to advance the cleaning nozzle for cleaning the user's “wet” or the like with a longer stroke.

  Furthermore, since a normal toilet bowl requires a low tank, flush valve, etc. to be installed close to the rear, if the front of the case is moved backward so that the main case does not cover the bowl, the depth of the main case will decrease. End up. When the depth of the case is reduced, the cleaning nozzle must be configured to be compactly housed.

  Moreover, the cleaning nozzle not only simply ejects water, but also controls water discharge by combining a plurality of water flows as in the so-called “soft” mode, or a plurality of different directions and water flows as in the “bidet” mode. It is desirable to provide a function for switching the water outlet.

  The present invention has been made based on the recognition of such a problem, and includes a sanitary washing device that can be stored in a compact manner and can be advanced in a long stroke while having a switchable form of water discharge, and has a washing nozzle and the same.

That is, FIG. 5A shows a state in which the three-stage cleaning nozzle is accommodated in the sanitary washing toilet seat apparatus body 500, and FIG. 5B shows a state in which the cleaning nozzle has advanced into the bowl 310.

  The cleaning nozzle 530 includes a substantially cylindrical first support portion 534 provided on the mounting base 532, a substantially cylindrical second support portion 536 slidably provided in the first support portion, and a second And a water discharger 538 slidably provided in the support part. A water supply tube 537 is connected to the water discharger 538 so that hot water or water can be jetted from a water discharge port (not shown) provided near the tip toward the user's “buttock” or the like.

  Further, as illustrated in FIG. 2, a water channel 534 </ b> T may be provided in the first support portion 534. The water channel 534T is communicated with a water outlet 534W opened inward in the vicinity of the tip of the first support portion 534, and water is discharged from the water supply tube 533 inward from the water outlet 534W through the water channel 534T. Thus, it becomes possible to clean the surfaces of the second support part 536 and the water discharge part 538.

FIG. 3 is a schematic diagram showing the internal structure of the water discharger 538 of the cleaning nozzle of this example.
FIG. 4 is a schematic enlarged view of the water discharger 538.
FIG. 5 is a schematic perspective view illustrating the structure near the tip of the water discharger 538.

  Near the tip of the water discharger 538, a first water outlet 702, a second water outlet 704, and a third water outlet 706 are provided. These spouts can be appropriately used for various purposes such as normal “wet cleaning”, “soft mode” “wet cleaning”, and “bide cleaning”. That is, by appropriately adjusting the structures, opening diameters, water discharge directions, and the like of the water discharge ports 702 to 706, various water flows according to the user's preference and application can be used properly.

  These water discharge ports 702 to 706 are connected to the switching mechanism 700 by connection tubes 710, 712, and 714. The switching mechanism 700 includes a stator 720 and a rotor 730. As will be described later in detail, the stator 720 is provided with a plurality of water outlets corresponding to the number of water outlets, and the connection tubes 710, 712, and 714 connect the water outlets to the water outlets 702 to 706, respectively. is doing. On the other hand, a rotor 730 is provided adjacent to the upstream side of the stator 720. The rotor 730 is connected to the output shaft 742 of the motor 740 and rotates, and has a role of opening any one of the water openings provided in the stator 720. The water supplied from the water supply tube 537 is supplied to the distribution chamber 738 through the water passage 736. The water introduced into the distribution chamber 738 is guided to one of the first to third water outlets 702 to 706 through the water outlet selected by the rotation of the rotor 730 and discharged.

  A partition plate 734 is provided between the distribution chamber 738 and the motor 740, and a waterproof structure is formed by the Y packing 732. That is, when viewed from the partition plate 734, the motor 740 side is in the atmospheric atmosphere, and water leakage to the motor 740 can be reliably prevented.

FIG. 6 is a front view of the stator 720. That is, this figure is a schematic view of the stator 720 viewed from the direction of arrow A in FIG.
The stator 720 is provided with three water outlets 722, 724, and 726 in accordance with the number of water outlets 702 to 706. These water outlets 722, 724, and 726 are connected to the first water outlets 702, 704, and 706 by connection tubes 710, 712, and 714, respectively (see FIGS. 3 and 5).

FIG. 7 is a front view of the rotor 730. That is, this figure is a schematic view of the rotor 730 viewed from the direction of arrow A in FIG.
The rotor 730 is provided with a water passage 731. This water flow port 731 communicates with any of the three water flow ports 722, 724, and 726 provided in the stator 720 according to the rotation angle of the rotor 730, and determines a water discharge water channel.

FIG. 8 is a schematic diagram for explaining the operation of the switching mechanism 700 using the stator 720 and the rotor 730.
That is, FIG. 7A shows the “water stoppage state” of the switching mechanism 700. At this time, the rotor water inlet 731 does not communicate with any of the stator water inlets 722, 724, and 726, and the water in the distribution chamber 738 (see FIG. 3) is not supplied to any of the water outlets 702 to 706.
Next, FIG. 8B shows a state in which the first water inlet 722 is selected by the switching mechanism 700. At this time, the rotor water inlet 731 communicates with the stator water inlet 722, and the water in the distribution chamber 738 is supplied to the water outlet 702 (see FIG. 5).
FIG. 8C shows a state in which the second water inlet 724 is selected by the switching mechanism 700. At this time, the water passage 731 of the rotor communicates with the water passage 724 of the stator, and the water in the distribution chamber 738 is supplied to the water outlet 704 (see FIG. 5).
Next, FIG. 8D shows a state in which the third water inlet 726 is selected by the switching mechanism 700. At this time, the rotor water inlet 731 communicates with the stator water inlet 726, and the water in the distribution chamber 738 is supplied to the water outlet 706 (see FIG. 5).
As described above, according to the present embodiment, any one of the first to third water discharge ports 702 to 706 can be selected and discharged by appropriately rotating the rotor 730.

Further, according to the present embodiment, the amount of water can be adjusted by controlling the rotation angle of the rotor 730.
FIG. 9 is a schematic diagram for explaining a method of controlling the amount of water.
That is, as shown in FIGS. 4A to 4C, the rotor water flow port 731 is appropriately displaced with respect to the stator water flow port 722, thereby restricting the opening of the communication port and reducing the conductance of the water channel. be able to. As a result, the water pressure (or water amount) supplied to the water discharge port can be controlled to a desired level. FIG. 9A shows the case where the water pressure is reduced, FIG. 9B shows the case where the water pressure is increased, and FIG. 9C shows the case where the water pressure is set to the maximum level. If a stepping motor is used as the motor 740 for rotating the rotor 730, such an angle adjustment is surely and easily performed.
As described above, according to the present embodiment, by appropriately rotating the rotor 730, one of the first to third water outlets 702 to 706 is selected and discharged, or the water pressure (or The amount of water) can be adjusted to the desired level.
According to the present embodiment, as illustrated in FIG. 3, the water discharge port switching mechanism using the stator 720 and the rotor 730 and the motor 740 are incorporated in the water discharge portion 538, so that one water discharge portion 538 is provided. It is only necessary to connect the water supply tube 537. That is, only one water supply tube 537 that reaches the water discharger 538 through the first supporter 534 and the second supporter 536 can be provided. As a result, the multistage cleaning nozzle can be smoothly advanced and retracted without being interfered with the water supply tube.

FIG. 10 is a schematic cross-sectional view showing the structure of the cleaning nozzle of the comparative example.
That is, in the case of this comparative example, the switching mechanism 700 is provided in the vicinity of the proximal end portion of the first support portion 534. In this case, the water supply to the switching mechanism 700 may be only one water supply tube 537. However, it is necessary to connect the connection tubes 710, 712, and 714 from the switching mechanism 700 to the water discharge ports 702, 704, and 706 provided at the tip of the water discharge unit 538, respectively. The first support portion 534, the second support portion 536, and the water discharge portion 538 are each preferably formed in a substantially cylindrical shape, but the internal space is limited, and when three connection tubes are piped, these connections are made. The tube interferes with the operation of the advance and retreat of the cleaning nozzle 530, and it becomes difficult to incorporate other elements such as a driving force transmitting element.

In particular, as shown in FIGS. 1 and 2, when the front surface 510 is retracted to the rear end of the bowl 310 so that the sanitary washing toilet seat body 500 does not extend over the bowl 310 of the toilet bowl, the sanitary washing toilet seat device The depth dimension of the main body 500 is limited. Therefore, it is necessary to make the cleaning nozzle 530 compact and to have a multistage structure that can be advanced with a long stroke. In such a case, piping a plurality of connection tubes inside the nozzle more often causes technical problems.
On the other hand, according to this specific example, the switching mechanism 700 and the motor 740 are accommodated in the water discharge portion 538 at the tip of the cleaning nozzle 530, so that the water pipe in the cleaning nozzle is only required by one water supply tube. Can do. As a result, even in the case of a multi-stage structure, it is possible to realize a cleaning nozzle that can be advanced and retracted smoothly, stored compactly, and advanced with a long stroke. In addition, although it is necessary to wire the motor 740 (not shown), the electrical wiring is much thinner and more flexible than the water piping. Therefore, there is almost no hindrance to the advance / retreat operation of the cleaning nozzle.

  In addition, as another aspect of the cleaning nozzle 530 suitable for application of the present invention, water is selectively or simultaneously supplied from two or more of the water outlets 722, 724, and 726 to one water outlet. In this way, there can be mentioned a type of cleaning nozzle that controls the cleaning from the water outlet in various ways by combining a plurality of flow paths.

  FIG. 11 is a schematic view illustrating a cleaning nozzle in which a plurality of flow paths are connected to one water outlet. In the cleaning nozzle of this specific example, a swirl chamber 707 is provided in a water discharge portion 538, and a water discharge port 708 opened above the axial center is formed. Water is supplied to the swirl chamber 707 via the first connection tube 710 and the second connection tube 712, respectively. These connection tubes 710 and 712 are connected to the switching mechanism 700 as described above with reference to FIGS.

  Water introduced through the first connection tube 710 flows toward the axis of the swirl chamber 707. Thus, the water that flows in toward the axial center flows upward along the axis of the swirl chamber 707 as shown by the arrow W1, and forms straight-running water S1 that goes straight in a substantially cylindrical shape.

On the other hand, the water introduced through the second connection tube 712 flows along the inner peripheral wall surface of the swirl chamber 707. Thus, the water flowing along the inner peripheral wall surface forms a swirling flow as indicated by the arrow W2 in the substantially cylindrical swirling chamber 707, and forms swirling spout S2 spreading spirally from the spout 708. To do.
The rectilinear water discharge S1 can strongly wash a narrow range such as “wet” and has a relatively small soft touch because the amount of air involved is small. On the other hand, the swirling water S2 can softly wash a wide range such as “wet”. In addition, since the amount of air entrained is large, the soft touch is relatively large.

  According to the present invention, the switching mechanism 700 can be switched between the first connection tube 710 and the second connection tube 712 to supply water, thereby switching between the straight water discharge S1 and the swirl water discharge S2. Accordingly, by providing such a water discharge port 708 at the tip of a long-stroke cleaning nozzle or the like and housing the switching mechanism 700 near the tip, various forms of water discharge from one water discharge port can be controlled. Is possible.

  Furthermore, if the water flow port 731 of the rotor 730 of the switching mechanism 700 is simultaneously communicated with two water flow ports among the water flow ports 722, 724, and 726 of the stator 720, the first connection tube 710 and the second connection tube 710 are connected. Since water is supplied from both of the tubes 712 at the same time, it is possible to strongly wash a wide area.

FIG. 12 is a schematic cross-sectional view illustrating a second specific example of the present embodiment. In this figure, the same elements as those described above with reference to FIGS. 1 to 10 are denoted by the same reference numerals, and detailed description thereof is omitted.
Also in this specific example, the switching mechanism 700 is built in the water discharger 538. However, the motor 740 for driving the switching mechanism 700 is attached not to the inside of the water discharge portion 538 but to the base end portion. This structure is advantageous when the size of the motor 740 is slightly larger.
Also in this specific example, when the motor 740 rotates the rotor 730, one of the water flow ports provided in the stator 720 is selected, and the water in the distribution chamber 738 is supplied to the corresponding water discharge port. Since the water pipe to the water discharger 538 is only the water supply tube 537, in the multistage nozzle, the advancement / retraction operation receives interference from the connection tube, and there is a space for incorporating the nozzle drive mechanism and the like. The problem of disappearing can be solved.

By the way, in the present embodiment, the cleaning nozzle can be provided with only one water supply tube 537, but the long water supply tube 537 is used as a nozzle in a case where the nozzle is multistage and a long stroke is advanced and retracted. It is desirable to prevent the advancement / retraction from occurring or to interfere with other elements in the sanitary washing toilet seat apparatus body 500.
FIG. 13 is a schematic view illustrating a sanitary washing toilet seat device body 500 provided with a water supply tube winding mechanism.
That is, a winding mechanism 750 is provided adjacent to the cleaning nozzle 530. The winding mechanism 750 includes a rotating drum 752 and a motor 754 that rotates the rotating drum 752. The water supply tube 537 extending from the cleaning nozzle 530 is appropriately wound around the rotary drum 752, and the water supply port 759 can be maintained in a fixed state. When the cleaning nozzle 530 moves backward, the motor 754 winds the water supply tube 537 by rotating the rotating drum 752 in accordance with the operation. When the cleaning nozzle 530 advances, the water supply tube 537 can be sent out by rotating the rotating drum 752 in accordance with the operation.
In this case, the motor 754 may be used in combination with a power source of a drive mechanism that advances and retracts the cleaning nozzle 530, or may be provided as an independent power source.
By providing such a winding mechanism 750, when the cleaning nozzle 530 is retracted, the water supply tube 537 interferes with other elements in the sanitary cleaning toilet seat apparatus body 500, thereby obstructing the retracting operation, or excessively. In addition, problems such as the water supply tube 537 being twisted or twisted or being caught by other elements and hindering the advance operation of the cleaning nozzle 530 can be solved.

FIG. 14 is a schematic diagram illustrating another specific example of the winding mechanism 750.
That is, in this specific example, the rotary drum 752 is rotatably attached to the water supply flange 756. Water is supplied from the water supply port provided in the water supply flange 756 to the introduction chamber 751 in the rotating drum. Further, a waterproof seal 758 is provided between the water supply flange 756 and the rotating drum 752 to prevent water leakage while ensuring a rotating operation. On the other hand, the rotary drum 752 is provided with a takeout port 753, and the water supply tube 537 is connected to the takeout port 753. The other end of the water supply tube 537 is connected to a switching mechanism 700 built in the water discharger 538 of the cleaning nozzle 530 as illustrated in FIG. 3 and FIG.
Also in this specific example, by rotating the rotating drum 752 in accordance with the advance / retreat of the cleaning nozzle 530, the surplus water supply tube 537 can be appropriately wound or sent out.

In the present embodiment, an accommodation mechanism that pulls in or feeds the water supply tube 537 as the cleaning nozzle 530 advances and retreats may be provided.
15 and 16 are schematic views illustrating the housing mechanism of the water supply tube 537. FIG. That is, FIG. 15 shows a state where the cleaning nozzle 530 has advanced, and FIG. 16 shows a state where the cleaning nozzle 530 is housed.
The accommodation mechanism 760 includes a guide plate 762, a pulley 764 provided on the back surface thereof, and a spring 766 that pulls the pulley 764 in the direction of arrow A. The guide plate 762 faces the case back plate 500R of the sanitary washing toilet seat device main body 500, and forms an accommodation space for accommodating the water supply tube 537 therebetween. The pulley 764 and the spring 766 have an action of drawing the water supply tube 537 in the direction of the arrow A in this accommodation space. A roller 768 is provided at the base end of the cleaning nozzle 530 so that the water supply tube 537 is smoothly guided to the accommodation space.

As shown in FIG. 15, when the cleaning nozzle 530 has advanced, the pulley 764 moves toward the base end of the cleaning nozzle 530 on the back surface of the guide plate 762, and the water supply tube 537 is smoothly fed out. Yes.
On the other hand, in the state where the cleaning nozzle 530 is retracted and stored as shown in FIG. 16, the pulley 764 and the spring 766 draw the water supply tube 537 in the direction indicated by the arrow A, so that the slim storage space is formed. Can be accommodated well.
By providing such a storage mechanism 760, the surplus water supply tube 537 interferes with other elements in the sanitary washing toilet seat apparatus main body 500, twists or twists, and is caught by other elements to advance the washing nozzle 530. Can solve problems such as obstruction of operation.

Next, an example of the drive mechanism of the cleaning nozzle 530 of this embodiment will be described.
FIGS. 17 and 18 are schematic cross-sectional views illustrating drive mechanisms for cleaning nozzles that can be provided in this embodiment.
That is, the mounting base 532 is provided with a first motor 652, a second motor 654, and a third motor 656, respectively. The first motor 652 slides the first support part 534. As the power transmission mechanism, for example, various types such as a belt type, a gear type, and a wire type can be used.
Further, the second motor 654 slides the second support portion 536 relative to the mounting base 532, for example, by feeding or pulling back the wire 662 guided by the wire guide 663. The third motor 656 also slides the water discharger 538 relative to the mounting base 532 by sending or pulling back the wire 664 guided by the wire guide 665, for example.
Thus, by providing the three motors 652, 654, 656, the three-stage cleaning nozzle can be advanced and retracted in a predetermined sequence.
Note that the drive mechanism used in the present embodiment is not limited to those illustrated in FIGS. 17 and 18. For example, by appropriately combining one motor and an urging means such as a spring, it is possible to advance and retreat a three-stage or other multi-stage cleaning nozzle in a predetermined sequence.

FIG. 19 is a schematic diagram showing another specific example of the sanitary washing toilet seat device of the present embodiment.
That is, this figure shows a state in which the toilet seat is removed from the sanitary washing toilet seat device. In this specific example, the sanitary washing toilet seat apparatus main body 500 does not extend to the bowl 310, and the front surface 510 is curved along the shape of the opening of the bowl 310 of the sitting toilet 300. Here, “rear” means a side on which a normal low tank 200, a flash valve, and the like are installed, as shown in FIG. 1, and means a side far from the user in a normal use mode. And the extension part 500P extended toward the front is provided in the right and left of this curved front surface 510. As shown in FIG.
