It is set in. Each of these pair of private part cleaning nozzles 7 advances forward from the nozzle opening 3 and projects inside the toilet main body 4 during cleaning, and after cleaning, retreats through the nozzle opening 3 into the nozzle cover 6 and the casing 5 and is held there. Ru.

For example, the pair of private part cleaning nozzles 7 are individually moved forward and backward in the direction of the axis O2 by a nozzle movement mechanism. The nozzle advancing/retracting mechanism of this embodiment includes a rack, a pinion, and a motor, and is constructed by integrally providing a rack on the lower surface of each local cleaning nozzle 7, and meshing this rack with a pinion attached to the rotating shaft of the motor. There is.

As a result, when the motor and pinion rotate in one direction in response to a remote control operation or the like, the private part cleaning nozzle 7 moves forward in the direction of the axis O2 and projects into the inside of the toilet main body 4 through the nozzle opening 3. When the motor and pinion rotate in the other direction in response to remote control operation, etc., the private part cleaning nozzle 7 is located at the rear in the direction of the axis O2 and moves to the inside of the casing 5, and the private part cleaning nozzle 7 is connected to the nozzle cover 6 through the nozzle opening 3. and housed in the casing 5.

The private parts cleaning device 2 includes a shutter unit 20, in which a pair of private parts cleaning nozzles 7 are retracted into the casing 5 and the nozzle openings 3 are closed (see FIG. 2) to remove dirt and cleaning water. A shutter 12 is provided to prevent droplets from splashing onto the private part cleaning nozzle 7 or entering the inside thereof, and to open the nozzle opening 3 when the private part cleaning nozzle 7 advances (see FIG. 3).

As shown in FIGS. 2 to 9, the shutter unit 20 of the present embodiment is provided in the casing 5, and is moved approximately along the axis O2 direction of the private part cleaning nozzle 7 by a shutter movement mechanism including, for example, a rack, a pinion, and a motor. A reciprocating member 21 that moves back and forth in the front-back direction T1, a shutter 12 rotatably connected to the tip end of the retracting member 21 by a hinge 22, and a shutter 12 that is provided inside the casing 5 and retreats together with the retracting member 21 is housed. The cleaning mechanism 24 is provided integrally with the shutter storage section 23.

The advancing/retracting member 21 of this embodiment is composed of a first advancing/retracting member 21a and a second advancing/retracting member 21b, and the tip of the first advancing/retracting member 21a moves back and forth along the axis O2 direction of the private part cleaning nozzle 7 by driving the shutter advancing/retracting mechanism. The rear end portion of the second reciprocating member 21b is rotatably connected to the rear end portion by a pin. The advancing/retracting member 21 is arranged such that the tip of the second advancing/retracting member 21b is rotatably connected to the center of the rear end of the shutter 12 in the width direction T2 by a hinge 22.

The shutter advancing/retracting mechanism includes, for example, a rack, a pinion, and a motor, and is constructed by integrally providing the rack with the first advancing/retracting member 21a, and meshing the rack with a pinion attached to the rotating shaft of the motor. Note that the shutter unit 20 of the present embodiment is configured such that even if the shutter advancing/retracting mechanism malfunctions, the nozzle 7 can advance and press the shutter 12 to open the shutter 12. preferable.

As a result, when the motor and pinion rotate in one direction in response to remote control operation, the first advancing/retracting member 21a moves forward in the direction of the axis O2, as shown in the order of FIGS. 9, 8, 7, and 6. Then, the second advancing/retracting member 21b pin-connected to the first advancing/retracting member 21a advances and moves, and the shutter 12 is pushed out from the shutter storage portion 23 and rotates around the rotation axis O3 extending in the width direction T2, thereby opening the nozzle. Close opening 3.

When the motor and pinion rotate in the other direction in response to remote control operation, the first retractable member 21a retracts backward in the axis O2 direction, as shown in the order of FIGS. 6, 7, 8, and 9. The second advancing/retracting member 21b pin-connected to the first advancing/retracting member 21a is retracted, and the shutter 12 is drawn into and stored in the shutter storage portion 23 while rotating around a rotation axis O3 extending in the width direction T2.

In this embodiment, as shown in FIGS. 5 and 9, the shutter 12 is pulled in and housed in the shutter housing 23, with its surface 12a facing upward along the axis O2 direction of the private part cleaning nozzle 7. , are arranged with their backs facing downward.

Here, as shown in FIG. 10, the shutter advancing/retracting mechanism preferably includes a guide portion 25 that guides the opening/closing movement of the shutter 12 (and the advancing/retracting movement of the second advancing/retracting member 21b).

As shown in FIG. 11, the guide portion 25 that guides the opening/closing movement of the shutter 12 (and the forward/backward movement of the second advancing/retracting member 21b) is formed in an arc shape (a combination of circular arcs (and straight lines)), and the shutter 12 (the second The moving locus of the advancing/retracting member 21b) may be arcuate (a combination of arcs (and straight lines)). Note that the guide portion 25 of this embodiment is configured to guide the movement of the rotation axis (rotation axis O3) of the shutter 12. In other words, in this embodiment, the guide portion 25 is configured to guide the movement of the shutter 12 rather than its rotation.

The shutter advancing/retracting mechanism advances the advancing/retracting member 21 to push the shutter 12 outward from the shutter housing 23, and also presses the surface 12a of the shutter 12 to keep the shutter 12 in the closed state (closed posture) with the nozzle opening 3 closed. The camera is equipped with a shutter-closing mechanism that holds the shutter closed. Note that the shutter closing holding mechanism may be configured to hold the shutter 12 in the closed state using, for example, a spring, and there is no particular need to limit its configuration. The shutter 12 does not necessarily need to be firmly and firmly held in the closed state.

On the other hand, as shown in FIGS. 12 and 13 (FIGS. 4 to 9), the cleaning mechanism 24 of this embodiment is provided integrally with the upper part of the shutter storage section 23, and forms a shutter storage space. A plurality of discharge ports 26 open to the inner surface of the shutter, a cleaning water channel 27 communicating with the plurality of discharge ports 26 and supplying cleaning water W1 for shutter cleaning, and a hose or the like connected to the cleaning water channel 27 for cleaning. A cleaning water supply means for supplying water W1.

In this embodiment, the plurality of discharge ports 26 are arranged in a line from one end of the shutter storage section 23 to the other end at a predetermined interval in the width direction T2.

In the cleaning mechanism 24 configured as described above, for example, when the shutter 12 is stored in the shutter storage space of the shutter storage section 23, the cleaning water supply means is automatically driven, and the cleaning water supplying means is automatically driven to provide a plurality of discharge ports through the cleaning water flow path 27. Washing water W1 for shutter cleaning is discharged from 26.

As shown in FIGS. 4, 12, and 13, the discharged cleaning water W1 flows over substantially the entire surface 12a facing upward of the shutter 12 from the rear end of the shutter 12 toward the front end, and further By flowing from the rear end of the shutter 12 toward the front end of almost the entire surface of the back surface 12b facing downward of the shutter 12, droplets (dirt and washing water droplets) adhering to the shutter 12 are removed. This allows the shutter 12 to be cleaned.

At this time, in the state in which the shutter 12 is housed, the surface 12a is inclined downward as it goes forward, so that the cleaning water W1 easily flows on the surface 12a. By forming a gap at a predetermined interval between the back surface 12b of the shutter 12 and the lower surface of the shutter storage portion 23, the cleaning water W1 can be brought into contact with the back surface 12b and flowed.
Thereby, substantially the entire front and back surfaces of the shutter can be cleaned with the cleaning water W1 discharged from the cleaning mechanism 24.

Note that the shutter 12 may be configured to be cleaned by discharging the cleaning water W1 at an arbitrary timing by operating a cleaning operation button or the like by the user. The cleaning water W1 for shutter cleaning does not need to be particularly limited as long as it is a liquid that can clean the shutter 12, and includes not only water but also hypochlorous acid water, ozone water, surfactant-containing water, etc. Water or a liquid containing a disinfectant (sterilizing agent) or a detergent may be used. Furthermore, a combination of these may be used.

On the other hand, as shown in FIG. 4 and FIG. It may be configured such that the cleaning water W1 is discharged onto the back surface 12b of the shutter 12 to clean the back surface 12b while the shutter 12 is pulled out from the shutter 12.

As shown in FIGS. 6 to 9, the cleaning mechanism 24 moves the shutter 12 from the closed position in which it is pushed out from the shutter storage part 23 to the open position by retracting the shutter 12 into the shutter storage part 23 by driving the shutter advance/retraction mechanism. While moving from the open position to the closed position, the cleaning water W1 is discharged onto the front surface 12a of the shutter 12 according to the operation and posture of the shutter 12, and the front surface 12a and the back surface 12b of the shutter 12 are sequentially cleaned. It may be configured to clean.

4 and 5, the cleaning mechanism 24 is arranged at the rear end of the shutter 12 when the shutter 12 is housed, and in FIGS. 6 to 9, the cleaning mechanism 24 is arranged at the front side of the shutter 12. .

The cleaning mechanism 24 receives the detection result of the user detection means that detected the user (person) entering the toilet room, and cleans the shutter 12 in the closed position before using the flush toilet 1. It may also be configured such that it is wetted with cleaning water W1 in advance. In other words, a pre-cleaning operation may be performed to clean the shutter before a person detected by the user detection means uses the flush toilet 1. Although it is preferable to wet both the front and back sides 12a and 12b, it is also possible to wet only the front side 12a, which is particularly susceptible to dirt, or only the back side 12b. At the same time, the nozzle 7 may be pre-cleaned and the toilet bowl surface may be pre-cleaned.

The cleaning mechanism 24 discharges the cleaning water W1 from the common discharge port 26 when the shutter 12 is stored in the shutter storage section 23 and/or when the shutter 12 is pushed out from the shutter storage section 23, so that the cleaning water W1 is cleaned only by the shutter 12. Alternatively, the inner surface of the shutter storage section 23 may be cleaned. However, instead of using a common discharge port 26, separate discharge ports may be provided. With this configuration, when the shutter 12 is pushed out, the cleaning water W1 flows along the bottom surface of the shutter housing 23 to the back surface 12b of the shutter 12, thereby making it possible to clean the shutter 12.

The private parts cleaning device 2 and the flush toilet bowl 1 equipped with the same according to the present embodiment are first provided with a nozzle advance/retreat mechanism for advancing and retracting the private part cleansing nozzle 7 and a shutter advance/retreat mechanism for opening and closing the shutter 12. , it becomes possible to freely control opening and closing of the shutter 12 so that the private part cleaning nozzle 7 does not come into contact with the shutter 12.

This makes it possible to eliminate the inconvenience of dirt and the like adhering to the shutter 12 and the private part cleaning nozzle 7 due to the contact of the private part cleaning nozzle 7. Note that the shutter 12 of this embodiment is configured to open and close in conjunction with the advance and retreat of the private part cleaning nozzle 7 without contacting the private part cleaning nozzle 7.

The private part cleaning device 2 and the flush toilet bowl 1 of this embodiment include a cleaning mechanism 24, which discharges cleaning water W1 for shutter cleaning toward the shutter 12 to flush and remove droplets adhering to the shutter 12. , it becomes possible to perform sterilization treatment (sterilization treatment) on the shutter 12.

This makes it possible to open and close the nozzle opening 3 of the private part cleaning nozzle 7 and keep the shutter 12 (and the private part cleaning nozzle 7), to which droplets and the like tend to adhere, in a clean state.

The cleaning mechanism 24 discharges cleaning water W1 onto the front surface 12a of the shutter 12 housed in the shutter housing 23 to clean the front surface 12a, and, with the shutter 12 pulled out from the shutter housing 23, cleans the front surface 12a of the shutter 12. By discharging the cleaning water W1 to clean the back surface 12b, the entire shutter (both sides) can be suitably cleaned with a simple configuration, and the shutter 12 can be kept in a clean state. By using the common discharge port 26, the entire shutter (both sides) can be suitably cleaned, and the size of the cleaning mechanism 24 can be reduced.

While the cleaning mechanism 24 moves from the closed position to the open position, or from the open position to the closed position, the cleaning mechanism 24 cleans the front surface 12a and the back surface 12b of the shutter 12 according to the operation and posture of the shutter 12. By discharging the cleaning water W1 in order to clean the front surface 12a and back surface 12b of the shutter 12 in that order, the shutter 12 can be cleaned in conjunction with the opening and closing movements of the shutter 12.

Thereby, the private part cleaning nozzle 7 can be used to quickly wash and remove droplets adhering to the shutter 12, and the shutter 12 can be quickly sterilized. Separate time for cleaning is not required. Furthermore, since the cleaning water W1 can be discharged from a short distance over substantially the entire surface of the shutter 12, an excellent cleaning effect can be obtained. Therefore, it becomes possible to effectively and efficiently clean the shutter 12.

The cleaning mechanism 24 receives the detection result of detecting a user (person) entering the toilet room, and cleans the shutter 12 in the closed position before using the flush toilet 1 to wet the shutter 12 in advance. With this configuration, droplets and the like can be prevented from adhering to the shutter 12. Splashes and the like can be easily removed by cleaning the shutter 12 after use. This makes it possible to keep the shutter 12 in a clean state more effectively.

The cleaning mechanism 24 discharges the cleaning water W1 from the discharge port 26 with the shutter 12 stored in the shutter housing 23 and/or with the shutter 12 pushed out from the shutter housing 23, and cleans not only the shutter 12 but also the shutter 12. The inner surface of the shutter housing part 23 is configured to be cleaned.

Thereby, the shutter 12 can be washed and cleaned, and the shutter housing section 23 provided in the casing 5 can also be cleaned. Therefore, it is possible to prevent droplets removed from the shutter 12 from remaining in the shutter accommodating part 23, and it is possible to keep the shutter accommodating part 23 as well as the shutter 12 in a clean state.

In the private parts cleaning device 2 and the flush toilet bowl 1 of the present embodiment, the shutter advancing/retracting mechanism includes the guide section 25 that guides the opening/closing movement and advancing/retracting movement of the shutter 12 and the second advancing/retracting member 21b. The movement locus of the member 21b can be stabilized, and the shutter 12 and the second advancing/retracting member 21b can be suitably opened/closed and advanced/retracted.

The guide portion 25 that guides the opening/closing movement and forward/backward movement of the shutter 12 and the second advancing/retracting member 21b is formed in an arc shape (a combination of arcs), and the movement locus of the shutter 12 and the second advancing/retracting member 21b is formed in an arc shape (a combination of arcs). ), the movement area of the shutter 12 and the second advancing/retracting member 21b, that is, the occupied area required for opening and closing the shutter 12, can be reduced and space-saving, and the shutter 12 and the second advancing/retracting member 21b can be moved more smoothly. It becomes possible to open and close the member 21b and move it forward and backward.

In the private part cleaning device 2 and the flush toilet bowl 1 of this embodiment, the shutter advancing/retracting mechanism presses the surface 12a of the shutter 12 and includes a shutter holding part that holds the shutter 12 in a closed position that closes the nozzle opening 3. The shutter 12 in the closed position with the nozzle opening 3 closed can be prevented from swinging and swinging around the rotation axis O3 due to the action of gravity, etc., and the nozzle opening 3 can be firmly closed. .

The shutter holding section releases the state of holding the shutter 12 in the closed position with the nozzle opening 3 closed by the user's manual operation, and the shutter 12 in the closed position can freely rotate around the rotation axis O2. (swingable).

As a result, regardless of the movement of the private part cleaning nozzle 7 back and forth, the shutter 12 pushed outward from the shutter housing 23 by the user's manual operation etc. can be moved freely around the axis O3 to open and close the nozzle opening 3. It becomes possible to rotate. As a result, the user can freely open and close the shutter 12, and the private part cleaning nozzle 7 will not become unusable due to, for example, a power failure of the shutter 12, and ease of handling can be improved.

The present disclosure is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit thereof.

For example, in this embodiment, the entire shutter 12 is described and illustrated as being drawn into and housed inside the casing 5. Differently from this, a part of the shutter 12 may be arranged inside the casing 5 in the open position. Even in this case, it is possible to obtain the same effects as in this embodiment.

In the present embodiment, the cleaning mechanism 24 is configured to discharge cleaning water W1 to the shutter 12 and the shutter housing 23 to clean the shutter 12 and the shutter housing 23. On the other hand, the cleaning mechanism 24 may be configured to maintain the shutter 12 and the shutter housing 23 in a clean state by, for example, irradiating UV (ultraviolet light) and sterilizing (sterilizing, sterilizing). The shutter 12 and the shutter accommodating portion 23 may be kept in a clean state by using a combination of spraying the cleaning water W1 and UV irradiation as in this embodiment.
In this case, the same effect as in this embodiment can be obtained by irradiating UV to the shutter 12 in the closed position and open position, or by irradiating UV in conjunction with the opening/closing movement. It is possible to obtain the effect.

As shown in FIGS. 14 and 15, the two private part cleaning nozzles 7 and 8 for bidet cleaning and anal cleaning, and the two private part cleaning nozzles 7 and 8 for bidet cleaning and anal cleaning, respectively, are moved forward and backward. Two nozzle openings 3 may be provided, and two shutters 12 may be provided to open and close these two nozzle openings 3, respectively. In this case as well, the structure may be such that each shutter 12 can be cleaned by the cleaning mechanism 24, similarly to the present embodiment. With this configuration, when one private part cleaning nozzle 7 (8) is used, it is possible to prevent droplets from entering the casing 5 from the nozzle opening 3 on the other private part cleaning nozzle 8 (7) side. Although the present embodiment has been described as having two openings 3 for nozzles, one of the openings may be an opening for hot air drying or deodorization. The structure may include three or more openings and shutters 12.

As shown in FIGS. 16 and 17, a deodorizing mechanism and/or a hot air drying mechanism is provided inside the casing 5, and the shutter 12 is configured to be half open when the deodorizing mechanism and/or the hot air drying mechanism is operated. You may. In FIGS. 16 and 17, the reference numeral 30 indicates an air intake (opening) of the deodorizing mechanism or a hot air outlet (opening) of the hot air drying mechanism. In this case, it is possible to prevent droplets from entering the inside of the casing 5 during the operation of the deodorizing mechanism and/or the hot air drying mechanism. Basically, the opening for hot air drying and the opening for deodorizing are provided separately, and when the opening for hot air drying and the opening for deodorizing are provided, the hot air is directed to one side with the nozzles (7, 8) in between. One of the drying opening and the deodorizing opening is provided, and the other opening is provided on the other side.

In the present embodiment, the nozzle advancing/retracting mechanism for advancing and retracting the private part cleaning nozzles 7 and 8 and the shutter advancing/retracting mechanism for opening and closing the shutter 12 are each composed of a rack and pinion mechanism, but the nozzle advancing/retracting mechanism The shutter advancing/retracting mechanism may be any mechanism as long as it is capable of advancing and retracting the private part cleaning nozzles 7, 8 and the advancing/retracting member 21, and does not need to be limited to a rack and pinion mechanism as in this embodiment. For example, it may be configured with a piston cylinder (direct-acting actuator).

In this embodiment, the nozzle advancing/retracting mechanism and the shutter advancing/retracting mechanism are provided separately, but the nozzle advancing/retracting mechanism and the shutter advancing/retracting mechanism may be configured by using the same component.

In this embodiment, it is assumed that the discharge ports 26 of the cleaning mechanism 24 are aligned in the width direction T2 at predetermined intervals. There is no particular need to limit the number or position of the cleaning mechanism 24, this discharge port 26, and the UV irradiation means.

Although the present embodiment has been described as cleaning both the front surface 12a and the back surface 12b of the shutter 12, it may be configured to clean only the front surface 12a of the shutter 12 or only the back surface 12b of the shutter 12.

Further, as shown in FIG. 18, only a part of the shutter 12 is drawn into the casing 5 and housed, and the cleaning mechanism 24 sprays cleaning water W1 onto the housed part of the shutter 12, and the entire surface of the shutter 12 ( It may be configured to clean the front surface 12a and the back surface 12b). In this case, the structure can be made smaller and simpler than in the case where the entire shutter 12 is housed. Incidentally, in FIG. 18, the cleaning mechanism 24 is arranged above the base end of the shutter 12, and the shutter 12 is configured to open when pressed by the nozzle 7.
