When the hot air drying opening and the deodorizing opening are provided, one opening of the warm air drying opening and the deodorizing opening is provided on one side of the nozzle (7, 8), and the other is provided on the other side. An opening is arranged.

Here, in the local cleaning device 2 of the present embodiment, the advance / retreat of the local cleaning nozzles 7 and 8 and the opening / closing of the shutter 12 are interlocked with each other.

The nozzle / shutter interlocking mechanism 31 that interlocks the advance / retreat of the local cleaning nozzles 7 and 8 with the opening / closing of the shutter 12 advances and retreats the local cleaning nozzles 7 and 8 and interlocks with the advance / retreat of the local cleaning nozzles 7 and 8 to obtain the local cleaning nozzle. It is a mechanism that opens and closes the shutter 12 without contact with 7 and 8.

As shown in FIGS. 4 and 5, the nozzle / shutter interlocking mechanism 31 is a rotation shaft of the motor 32 of the drive source and the motor 32 extending in a direction orthogonal to the advancing / retreating direction (axis O2 direction) of the local cleaning nozzles 7 and 8. Nozzle drive pinion 33 attached to the nozzle drive pinion 33, a nozzle drive rack 34 extending in the advancing / retreating direction and connected to the local cleaning nozzles 7 and 8, and engaging the nozzle drive pinion 33, and a nozzle drive The opening / closing speed adjusting pinion 35, which has a larger diameter than the pinion 33 and meshes with the nozzle driving pinion 33, the shutter driving pinion 36 meshing with the opening / closing speed adjusting pinion 35, and the rotating shaft O3 are arranged coaxially. A shutter interlocking pinion 37 integrally provided with the shutter 12, a shutter driving pinion 36, and an endless transmission belt 38 wound around the shutter interlocking pinion 37 are provided.

As a result, when the motor 32 rotates in one direction in response to a remote control operation or the like, the local cleaning nozzles 7 and 8 move forward in the axis O2 direction. The local cleaning nozzles 7 and 8 move forward in the axis O2 direction, the shutter 12 opens without the tips of the local cleaning nozzles 7 and 8 abutting, and the local cleaning nozzles 7 and 8 pass through the nozzle opening 3. It protrudes inside the toilet bowl body 4.

When the motor 32 rotates in the other direction in response to a remote control operation or the like, the local cleaning nozzles 7 and 8 move backward in the axis O2 direction, and the local cleaning nozzles 7 and 8 move into the nozzle cover 6 and the casing 5 through the nozzle opening 3. Is housed in. At the same time, the shutter 12 closes and the nozzle opening 3 closes without the tips of the local cleaning nozzles 7 and 8 coming into contact with each other.

As shown in FIGS. 6 to 8, the shutter unit 20 of the local cleaning device 2 of the present embodiment rotates around the rotation shaft O3 in which the shutter 12 extends in the width direction T2 of the rear end portion and opens, and the casing 5 It is configured to be drawn inside the.

The shutter unit 20 of the present embodiment includes a shutter accommodating portion 23 provided in the casing 5 and accommodating the shutter 12 pulled into the casing 5 and retracted, and a cleaning mechanism 24 integrally provided in the shutter accommodating portion 23. , Is configured.

As a result, when the motor 32 rotates in one direction in response to a remote control operation or the like, the shutter 12 is pulled into the shutter storage portion 23 and stored while rotating around the rotation shaft O3 extending in the width direction T2. When the motor 32 rotates in the other direction in response to a remote control operation or the like, the shutter 12 is pushed outward from the shutter accommodating portion 23 and rotates around the rotation shaft O3 extending in the width direction T2 to close the nozzle opening 3.

Here, a shutter closing holding mechanism is provided which pushes the shutter 12 outward from the shutter accommodating portion 23, presses the surface 12a of the shutter 12, and holds the shutter 12 in a closed state (closed posture) in which the nozzle opening 3 is closed. ing. The shutter closing holding mechanism may be configured to hold the shutter 12 in the closed state by a spring, for example, and the configuration is not particularly limited. It is not always necessary to hold the shutter 12 firmly and firmly in the closed state.

The shutter 12 is arranged with the front surface 12a facing upward and the back surface 12b facing downward so as to be along the axis O2 direction of the local cleaning nozzles 7 and 8 in a state of being pulled in and housed in the shutter accommodating portion 23. ..

The cleaning mechanism 24 of the present embodiment is integrally provided on the upper portion of the shutter accommodating portion 23, and communicates with a plurality of discharge ports 26 which are integrally provided on the upper portion of the shutter accommodating portion 23 and which are opened on the inner surface of the shutter accommodating portion 23 forming the shutter accommodating space. The cleaning water flow path 27 for supplying the cleaning water W1 for shutter cleaning and the cleaning water supply means for supplying the cleaning water W1 by connecting a hose or the like to the cleaning water flow path 27 are provided.

In the present embodiment, a plurality of discharge ports 26 are arranged so as to be aligned from one side end to the other side end of the shutter accommodating portion 23 at a predetermined interval in the width direction T2.

For example, when the shutter 12 is stored in the shutter storage space of the shutter storage unit 23, the cleaning mechanism 24 automatically drives the cleaning water supply means and performs shutter cleaning from a plurality of discharge ports 26 through the cleaning water flow path 27. The cleaning water W1 is discharged.

Then, the discharged cleaning water W1 flows on substantially the entire surface of the front surface 12a facing upward of the shutter 12 from the rear end side of the shutter 12 toward the tip end, and further on substantially the entire surface of the back surface 12b facing downward of the shutter 12. On the other hand, by flowing from the rear end side of the shutter 12 toward the tip end, droplets (dirt and washing water droplets) adhering to the shutter 12 are removed, and the shutter 12 can be cleaned.

At this time, in the state where the shutter 12 is housed, the surface 12a is inclined downward toward the front, so that the cleaning water W1 can easily flow on the surface 12a. Since a gap of a predetermined interval is formed between the back surface 12b of the shutter 12 and the lower surface of the shutter accommodating portion 23, the cleaning water W1 can be brought into contact with the back surface 12b and flowed.
Thereby, substantially the entire surface of the front surface and the back surface of the shutter can be cleaned by the cleaning water W1 discharged from the cleaning mechanism 24.

The cleaning water W1 may be discharged at an arbitrary timing by operating the cleaning operation button of the user to clean the shutter 12. The cleaning water W1 for shutter cleaning is not particularly limited as long as it is a liquid capable of cleaning the shutter 12, and contains not only water but also, for example, hypochlorous acid water, ozone water, and a surfactant. It may be water, liquid or the like containing a sterilizing (sterilizing) agent or detergent such as water. Further, these combinations may be used.

The cleaning mechanism 24 cleans the surface 12a by discharging cleaning water W1 onto the surface 12a of the shutter 12 while the cleaning mechanism 24 is housed in the shutter storage unit 23, and pulls out the shutter 12 from the shutter storage unit 23. The cleaning water W1 may be discharged to the back surface 12b to clean the back surface 12b.

The cleaning mechanism 24 pulls the shutter 12 into the shutter housing 23 from the closed posture in which the shutter 12 is pushed out from the shutter housing 23 to move to the open posture, or moves from the open posture to the closed posture. In addition, the cleaning water W1 may be discharged to 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 may be cleaned in this order.

The cleaning mechanism 24 receives the detection result of the user detecting means that detects the user (person) who has entered the toilet room, and cleans the shutter 12 in the closed posture at the stage before using the flush toilet 1, and the shutter 12 May be configured to be pre-wet with cleaning water W1. In other words, the person detected by the user detecting means may be configured to perform a pre-cleaning operation of pre-cleaning the shutter before using the flush toilet 1.
It is preferable to wet both the front and back surfaces 12a and 12b, but only the front surface 12a to which dirt easily adheres may be wetted, or only the back surface 12b may be wetted. At the same time, the nozzles 7 and 8 may be pre-cleaned and the pot surface of the toilet bowl may be pre-cleaned.

The cleaning mechanism 24 discharges the cleaning water W1 from the common discharge port 26 in a state where the shutter 12 is stored in the shutter storage unit 23 and / or when the shutter 12 is pushed out from the shutter storage unit 23, and only the shutter 12 is used. Instead, it may be configured to clean the inner surface of the shutter accommodating portion 23. However, the discharge ports 26 may not be common, and each discharge port may be provided. In this configuration, the cleaning water W1 can be cleaned by flowing the cleaning water W1 to the back surface 12b of the shutter 12 along the bottom surface of the shutter accommodating portion 23 in a state where the shutter 12 is pushed out.

Then, in the local cleaning device 2 of the present embodiment and the flush toilet 1 provided with the local cleaning device 2, first, the nozzle / shutter interlocking mechanism 31 for interlocking the advance / retreat of the local cleaning nozzles 7 and 8 and the opening / closing of the shutter 12 is provided. It is possible to freely open and close the shutter 12 so that the local cleaning nozzles 7 and 8 do not come into contact with the shutter 12, that is, without contacting the local cleaning nozzles 7 and 8.

As a result, it is possible to eliminate the inconvenience that dirt or the like adheres to the shutter 12 and the local cleaning nozzles 7 and 8 due to the contact of the local cleaning nozzles 7 and 8.

The local cleaning device 2 and the flush toilet 1 of the present embodiment include a cleaning mechanism 24, discharge cleaning water W1 for shutter cleaning toward the shutter 12, and remove droplets and the like adhering to the shutter 12. , The shutter 12 can be sterilized (sterilized) or the like.

As a result, the nozzle openings 3 of the local cleaning nozzles 7 and 8 can be opened and closed, and the shutter 12 (and the local cleaning nozzles 7 and 8) to which droplets and the like easily adhere can be kept in a clean state.

The cleaning mechanism 24 discharges cleaning water W1 onto the surface 12a of the shutter 12 stored in the shutter storage 23 to clean the surface 12a, and with the shutter 12 pulled out from the shutter storage 23, the cleaning mechanism 24 is placed on the back surface 12b 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, so that the size of the cleaning mechanism 24 can be reduced.

While the cleaning mechanism 24 moves from the closed posture to the open posture, or from the open posture to the closed posture, the cleaning mechanism 24 is placed on the front surface 12a and the back surface 12b of the shutter 12 depending on the operation and posture of the shutter 12. By sequentially discharging the cleaning water W1 and cleaning the front surface 12a and the back surface 12b of the shutter 12 in order, the shutter 12 can be cleaned in conjunction with the opening / closing movement of the shutter 12.

As a result, the local cleaning nozzles 7 and 8 can be used to quickly clean and remove droplets and the like adhering to the shutter 12, and the shutter 12 can be sterilized quickly. No additional cleaning time is required. Further, since the cleaning water W1 can be discharged from a short distance to substantially the entire surface of the shutter 12, an excellent cleaning effect can be obtained. Therefore, the shutter 12 can be cleaned effectively and efficiently.

The cleaning mechanism 24 receives the detection result of detecting the user (person) who has entered the toilet room, and cleans the shutter 12 in the closed posture before using the flush toilet 1 to pre-wet the shutter 12. With such a configuration, it is possible to prevent droplets and the like from adhering to the shutter 12. By cleaning the shutter 12 after use, it is possible to easily remove droplets and the like. 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 in a state where the shutter 12 is stored in the shutter storage unit 23 and / or when the shutter 12 is pushed out from the shutter storage unit 23, and not only the shutter 12 but also the shutter 12 It is configured to clean the inner surface of the shutter accommodating portion 23.

As a result, the shutter 12 can be cleaned and cleaned, and the shutter accommodating portion 23 provided in the casing 5 can also be cleaned. Therefore, it is possible to prevent the droplets removed from the shutter 12 from remaining in the shutter accommodating portion 23, and it is possible to keep the shutter accommodating portion 23 in a clean state together with the shutter 12.

In the local cleaning device 2 and the flush toilet 1 of the present embodiment, the shutter advancing / retreating mechanism presses the surface 12a of the shutter 12 and includes a shutter holding portion that holds the shutter 12 in a closed posture in which the nozzle opening 3 is closed. It is possible to prevent the shutter 12 in the closed posture with the nozzle opening 3 closed from swinging and swinging around the rotation shaft O3 due to the action of gravity, and the nozzle opening 3 can be closed firmly. ..

The shutter holding portion releases the state in which the shutter 12 in the closed posture with the nozzle opening 3 closed is released by the manual operation of the user, and the shutter 12 in the closed posture is caused by the action of gravity or the like to rotate the shaft O2. It is configured to be switchable so that it rotates and swings around.

As a result, regardless of the advancement and retreat of the local cleaning nozzles 7 and 8, the shutter 12 pushed outward from the shutter storage portion 23 by the user's manual operation or the like can freely open and close the nozzle opening 3 along the axis O3. It becomes possible to rotate around. As a result, the user can freely open and close the shutter 12, and for example, the local cleaning nozzles 7 and 8 are not disabled due to a power failure of the shutter 12, and the handleability can be improved.

As described above, the present disclosure is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.

For example, in the present embodiment, the entire shutter 12 has been described and illustrated as being pulled into the casing 5 and stored. Unlike this, a part of the shutter 12 may be arranged inside the casing 5 in the open posture. Even in this case, it is possible to obtain the same effect as that of the present embodiment.

In the present embodiment, the cleaning mechanism 24 is configured to discharge the cleaning water W1 to the shutter 12 and the shutter accommodating portion 23 to clean the shutter 12 and the shutter accommodating portion 23. Unlike this, the cleaning mechanism 24 may be configured to keep the shutter 12 and the shutter accommodating portion 23 in a clean state by, for example, irradiating with UV (ultraviolet rays) and sterilizing (sterilizing, sterilizing) the shutter 12. The shutter 12 and the shutter accommodating portion 23 may be maintained in a clean state by using the discharge water of the washing water W1 and the irradiation of UV as in the present embodiment in combination.
Also in this case, the same operation as that of the present embodiment is performed in the same manner as in the present embodiment, that is, by irradiating the shutter 12 in the closed posture and the open posture with UV or irradiating the UV in conjunction with the opening / closing movement. It is possible to obtain an effect.

In the present embodiment, it is assumed that the discharge ports 26 of the cleaning mechanism 24 are aligned and arranged at a predetermined interval in the width direction T2. The number and position of the cleaning mechanism 24, the discharge port 26, and the UV irradiation means need not be particularly limited.

In the present embodiment, the description has been made assuming that both the front surface 12a and the back surface 12b of the shutter 12 are cleaned, but only the front surface 12a of the shutter 12 and only the back surface 12b of the shutter 12 may be cleaned.

Further, as shown in FIG. 9, only a part of the shutter 12 is pulled into the casing 5 and stored, and the cleaning water W1 is discharged to the stored portion of the shutter 12, and the entire surface (front surface 12a or back surface 12a) of the shutter 12 is discharged. It may be configured to perform the cleaning of 12b). In this case, the structure can be miniaturized and simplified as compared with the case where all the shutters 12 are housed.
Incidentally, in FIG. 9, the cleaning mechanism 24 is arranged above the base end portion of the shutter 12. However, the position of the cleaning mechanism 24 does not have to be limited as shown in FIG. 9, and may be appropriately set so that the shutter 12 can be appropriately cleaned.
