JP 2002-294822 A JP 2001-227037 A

  When moving the nozzle cleaning chamber when the nozzle advances or retreats, after the user operates the “Human cleaning” switch on the main unit or remote control, the nozzle cleaning chamber moves forward, and after cleaning the nozzle, the nozzle moves further forward and is used. Water is sprayed toward the “butt” of the person. Therefore, the waiting time from when the user operates the switch until water is jetted may be slightly longer.

  On the other hand, the main body case of the conventional sanitary washing toilet seat device is configured to extend to the bowl side of the sitting toilet and close a part of the bowl opening. 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, if it is installed so that the main body case does not extend above the bowl of the toilet bowl, it will not become dirty and will look neat.

  However, when the main unit case is installed so as not to extend over the bowl of the toilet bowl, it is easy to drop the drainage into the bowl unless cleaning is performed with the nozzle cleaning chamber extended from the main unit case. is not. Further, when the main body case is retracted in this way, the advance length to a predetermined position where the nozzle injects water toward the user's “butt” or the like becomes long. Therefore, after the user operates the “human body cleaning” switch, the nozzle cleaning chamber advances to clean the nozzle, and the waiting time until the nozzle advances and water is sprayed on the “buttock” is further increased. Become.

  The present invention has been made on the basis of recognition of such a problem, and provides a sanitary washing device having a washing nozzle that operates quickly and reliably and a toilet device having the same.

  Further, in this case, when the user instructs human body cleaning, the nozzle cleaning chamber advances from the main body and the water discharge portion advances in a state where the support portion is retracted, so that at least a part thereof is the nozzle cleaning chamber. If the support is advanced and then at least a part of it is cleaned in the nozzle cleaning chamber, the body of the three-stage nozzle can be reliably cleaned, and the cleaning nozzle is always clean. It becomes easy to maintain the state.

  On the other hand, the apparatus further includes a plurality of support portions composed of a plurality of support portions supported so as to be capable of moving forward and backward relative to the nozzle cleaning chamber, and If so, a so-called four-stage type or more multi-stage type washing nozzle can be realized, and the water discharge section can be advanced farther because it can be stored more compactly.

  In this case, when the user commands human body cleaning, the nozzle cleaning chamber advances from the main body, and at least a part of the water discharger advances in a state in which each of the plurality of support parts retracts. If cleaning is performed in the nozzle cleaning chamber, and then the plurality of support portions are sequentially advanced from the water discharge portion side so that the plurality of support portions are sequentially cleaned in the nozzle cleaning chamber. It is possible to reliably clean the body of a multi-stage nozzle of the type or higher, and to easily keep the cleaning nozzle clean.

  On the other hand, the nozzle cleaning chamber is fixed to a mounting base, the water discharger is supported so as to be able to advance and retreat with respect to the mounting base, and the nozzle cleaning chamber can be advanced and retracted by movement of the mounting base. Then, the nozzle cleaning chamber can be surely advanced with a simple moving mechanism.

  Or, further comprising a cylinder portion provided with the nozzle cleaning chamber at the tip, and a mounting base that supports the cylinder portion so as to be able to advance and retreat, the nozzle cleaning chamber can be advanced and retracted by the advance and retreat of the cylinder portion, If the water discharger is formed in the shape of a piston that can be projected and retracted with respect to the cylinder, it can be stored compactly and the nozzle cleaning chamber can be reliably advanced.

Moreover, according to the other one aspect | mode of this invention, the toilet apparatus provided with the seat toilet and one of said sanitary washing toilet seat apparatuses is provided.
According to the said structure, the toilet apparatus provided with the washing nozzle which operate | moves quickly and reliably can be provided.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet apparatus provided with the washing nozzle which operate | moves quickly and reliably can be provided.

That is, FIG. 3 shows a state in which the two-stage cleaning nozzle is housed in the sanitary washing toilet seat apparatus body 500, and FIG. 4 shows a state in which this cleaning nozzle has advanced into the bowl 310.

  The cleaning nozzle 530 includes a substantially cylindrical first support portion 534 provided so as to be freely advanced and retracted by a drive mechanism (not shown), a piston-like water discharger 538 provided so as to be freely advanced and retracted in the first support portion, and a first support portion. And a nozzle cleaning chamber 540 provided near the tip of 534. The nozzle cleaning chamber 540 may be provided as a part of the first support part 534, or may be provided separately from the first support part 534.

A water outlet 538W is provided in the vicinity of the tip of the water discharger 538 so that water for washing the human body can be sprayed toward the user's “buttock” or the like. In addition, the nozzle cleaning chamber 540 is formed so as to surround the water discharge portion 538, and by discharging water from a water discharge port 540W that opens toward the inside thereof, the tip of the water discharge portion 538, the body portion, and the like can be cleaned. ing.
The cleaning nozzle 530 in the present invention is not limited to the two-stage type as illustrated in FIGS. 3 and 4, and is a one-stage type in which the water discharger 538 and the first support part 534 are integrated. It may be a thing. Furthermore, as will be described in detail later, it may be a three-stage type or a multi-stage type.

  On the other hand, in the sanitary washing toilet seat apparatus body 500, for example, a “warm air drying function” for drying a wet “buttock”, a “toilet seat heating function” for heating the toilet seat 410, and an odor in the sitting toilet are removed. A "deodorizing function" can be provided. It is also possible to provide an “automatic opening / closing function” that automatically opens the toilet lid 400 upon detecting the approach of the user and automatically closes the toilet lid 400 when the user is gone. These functions can be executed and set by appropriately operating an operation unit (not shown) provided in the sanitary washing toilet seat apparatus body 500, and a remote control (not shown) installed on the wall surface of the toilet or the like can be used. It is also possible to execute it by operating.

  Furthermore, an “automatic water washing function” for flowing washing water to the sitting toilet 300 by a remote control operation or the like may be added to the sanitary washing toilet seat device. This is provided with a drive mechanism for operating the drainage mechanism of the low tank 200 and the flush valve, and in conjunction with a remote control operation or a human body sensor, a signal for operating this drive mechanism is output from the sanitary washing toilet seat apparatus body 500 to This is a function for automatically flowing flush water to the toilet bowl 300.

  In the present embodiment, when the user sits on the toilet seat 410, the nozzle cleaning chamber 540 of the cleaning nozzle automatically advances to the outside of the sanitary cleaning toilet seat apparatus body 500 correspondingly.

5 to 7 are schematic views illustrating a first specific example of the operation of the sanitary washing toilet seat device of this embodiment.
FIG. 8 is a flowchart showing the operation of this example.

First, in the standby state, as shown in FIG. 5A, the cleaning nozzle 530 is accommodated in the sanitary cleaning toilet seat apparatus body 500 (step S102). That is, the first support portion 534, the water discharge portion 538, and the nozzle cleaning chamber 540 are each retracted and the closing plate 525 is closed.
Next, FIG. 5B shows a state where the user is sitting on the toilet seat 410. That is, when the user approaches the toilet bowl 300 and sits on the toilet seat 410, the seating sensor 502 (see FIG. 1) of the sanitary washing toilet seat apparatus body 500 detects (step S104). Then, together with the first support portion 534, the cleaning chamber 540 advances in the direction of the arrow A, and the nozzle cleaning chamber 540 is projected to the outside of the sanitary cleaning toilet seat apparatus body 500 (step S106). At this time, the water discharge port 538 </ b> W provided near the tip of the water discharge unit 538 is in the nozzle cleaning chamber 540. In this state, pre-cleaning is performed by jetting water from the water outlet 538W (step S108). The water sprayed from the water discharge port 538W is reflected by the inner wall of the nozzle cleaning chamber 540, and the inside of the nozzle cleaning chamber 540 and the tip of the water discharge portion 538 can be cleaned. Furthermore, the cold water remaining in the water supply tube or the like reaching the water discharge unit 538 is discharged and appropriately replaced with hot water. Thereby, when water injection is started to the user's “tail” or the like, it is possible to prevent the cold water from being released and making it feel “cold”.

  At this time, since the nozzle cleaning chamber 540 protrudes from the sanitary cleaning toilet seat device body 500 to the bowl 310, the pre-cleaning drainage D1 can be dropped into the bowl 310 as it is. That is, pre-cleaning can be performed without discharging waste water into the sanitary cleaning toilet seat apparatus body 500.

  Thereafter, until the user operates the sanitary washing toilet seat apparatus body 500 or a remote controller (not shown) to instruct “human body washing”, the nozzle washing chamber 540 has the bowl 310 as shown in FIG. Maintain the protruding state.

  When the user instructs “human body cleaning” by a switch operation (step S110), first, body cleaning of the water discharger 538 is started (step S112). That is, as shown in FIG. 6A, while the water is jetted from the water discharge port 540 </ b> W provided in the nozzle cleaning chamber 540 toward the water discharge unit 538, the water discharge unit 538 has an arrow with respect to the first support unit 534. Advances in the direction of A (step S114). Along with this advancement operation, the body of the water discharger 538 is washed from its tip toward the root. Also at this time, since the nozzle cleaning chamber 540 protrudes from the bowl 310, the body cleaning waste water D2 can be dropped into the bowl 310 as it is. When the water discharger 538 is completely advanced, water discharge in the nozzle cleaning chamber 540 is stopped, and the body cleaning is finished (step S116). By performing the body cleaning in this order, the water discharger 538 can be cleaned evenly, and the cleaning nozzle before use can be cleaned.

  Subsequently, as shown in FIG. 6B, water W for washing the human body is sprayed from the water outlet 538 </ b> W provided at the tip of the water discharger 538 toward the user ’s “buttock” or the like (step S <b> 118). ). In this way, the user's “wet” or the like can be cleaned by a clean cleaning nozzle that has been pre-cleaned or body-cleaned.

  When the user instructs to stop the “human body cleaning” by operating the switch (step S120), the water discharge from the water discharge port 538W is stopped (step S122), and the body cleaning of the water discharge unit 538 is started (step S124). That is, while discharging water from the water discharge port 540W of the nozzle cleaning chamber 540, the water discharge portion 538 is retracted into the first support portion 534 in the direction of arrow B as shown in FIG. 7A (step S126). Thus, the water discharge part 538 can be wash | cleaned toward the front-end | tip from the root. When the water discharger 538 is completely retracted into the first support part 534, water discharge from the water discharge port 540W is stopped, and the trunk cleaning is finished (step S128). In this way, it is possible to clean the cleaning nozzle after use by removing dirt or the like that has adhered when the user's “buttock” is cleaned.

  Subsequently, as shown in FIG. 7B, post-cleaning is performed (step S130). That is, water is ejected from the water outlet 538W of the water discharger 538. At this time, as in the case of the pre-cleaning, the water outlet 538W is in a state of being accommodated in the nozzle cleaning chamber 540, so that the inside of the nozzle cleaning chamber 540 and the tip of the water discharger 538 are ejected by ejecting water. Can be washed. Also in this case, since the nozzle cleaning chamber 540 protrudes into the bowl 310, the post-cleaning waste water D3 can be dropped into the bowl 310 as it is.

  When the user stands up from the toilet seat 410, the seating sensor 502 (see FIG. 1) is not detected (step S132), and the first support part 534 and the nozzle cleaning chamber 540 are retracted into the sanitary cleaning toilet seat apparatus body 500 (step). S134). Then, as shown in FIG. 5A, the cleaning nozzle 530 is accommodated in the sanitary cleaning toilet seat apparatus body 500 and returns to the standby state (step S136).

  As described above, according to this specific example, the waste water for pre-cleaning and body cleaning is dropped into the bowl 310 as it is by detecting the seating of the user and moving the nozzle cleaning chamber 540 into the bowl 310. Can do. In addition, when the user operates the “human body cleaning” switch, the water discharge unit 538 advances to complete the body cleaning, and water discharge from the water discharge port 538W can be started immediately. As a result, it is possible to reduce the waiting time from when the switch is operated until the water discharge is started, and to obtain comfortable operability.

Next, a specific example in which the present invention is applied to a three-stage cleaning nozzle will be described.
FIG. 9 is a schematic cross-sectional view showing the cleaning nozzle of this example. 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 provided in the first support portion so as to be movable back and forth, and a second support. And a water discharger 538 provided in the unit so as to freely advance and retract. A water outlet 538W is provided in the vicinity of the tip of the water discharger 538 so that hot water or water can be jetted toward the user's “buttock” or the like.

  In addition, a nozzle cleaning chamber 540 is provided near the tip of the first support portion 534. The nozzle cleaning chamber 540 has a water discharge port 540W that opens toward the inside, and discharges water from the water discharge port 540W toward the inside, so that the distal end portion and the body portion of the second support portion 536 and the water discharge portion 538 are formed. It can be washed.

As shown in FIG. 9A, the cleaning nozzle 530 is housed in the second support portion 536 except for its tip portion, and the second support portion 536 is the first support portion 536 in the accommodated state. The first support portion 534 is accommodated in the support portion 534 and is in a position retracted backward on the mounting base 532. As described above, the cleaning nozzle 530 has a three-stage structure, so that it can be stored compactly.
10 to 13 are schematic views illustrating the operation of the cleaning nozzle of this example.
FIG. 14 is a flowchart showing the operation of this example.

First, in the standby state, as shown in FIG. 10A, the cleaning nozzle 530 is accommodated in the sanitary cleaning toilet seat apparatus body 500 (step S202). That is, the 1st support part 534 (nozzle cleaning room 540), the 2nd support part 536, and the water discharge part 538 are retreating, respectively.
Next, FIG. 10B shows a state where the user is sitting on the toilet seat 410. That is, when the user approaches the toilet bowl 300 and sits on the toilet seat 410, the seating sensor 502 (see FIG. 1) of the sanitary washing toilet seat apparatus body 500 detects (step S204). Then, the 1st support part 534 advances in the direction of arrow A, and the nozzle washing | cleaning chamber 540 will be in the state protruded to the outer side of the sanitary washing toilet seat apparatus main body 500 (step S206). At this time, the second support part 536 and the water discharge part 538 are in a state of being retracted into the first support part 534. In this state, the pre-cleaning is performed by ejecting water W from the water outlet 538W of the water discharger 538 (step S208). Similarly to the “pre-cleaning” described above with reference to FIGS. 5 to 8, the water W sprayed from the water discharge port 538 </ b> W is reflected by the inner wall of the nozzle cleaning chamber 540, and the inside of the nozzle cleaning chamber 540 and the tip of the water discharge unit 538 are reflected. Can be washed. Furthermore, the cold water remaining in the water supply tube or the like reaching the water discharge unit 538 is discharged and appropriately replaced with hot water. Thereby, when water injection is started to the user's “tail” or the like, it is possible to prevent the cold water from being released and making it feel “cold”.

  Also at this time, since the nozzle cleaning chamber 540 protrudes from the sanitary cleaning toilet seat apparatus body 500 to the bowl 310, the pre-cleaning drainage D1 can be dropped into the bowl 310 as it is.

  Thereafter, until the user operates the sanitary washing toilet seat apparatus main body 500 or a remote controller (not shown) to instruct “human body washing”, the nozzle washing chamber 540 has the bowl 310 as shown in FIG. Maintain the protruding state.

  When the user instructs “human body cleaning” by a switch operation (step S210), first, body cleaning of the water discharger 538 and the second supporter 536 is started (step S212). That is, as shown in FIG. 11A, the water discharge portion 538 advances in the direction of arrow A with respect to the second support portion 536 while jetting water W from the water discharge port 540 </ b> W provided in the nozzle cleaning chamber 540. (Step S214). Along with this advancement operation, the body of the water discharger 538 is washed from its tip toward the root.

  Subsequently, with the water W being jetted from the water outlet 540W, as shown in FIG. 11B, the second support portion 536 advances in the direction of arrow A with respect to the first support portion 534 (step S216). ). Along with this advancement operation, the body of the second support portion 536 is cleaned from its tip toward the root. Also during the body cleaning, since the nozzle cleaning chamber 540 protrudes into the bowl 310, the body cleaning waste water W2 can be dropped into the bowl 310 as it is.

  If the 2nd support part 536 advances completely, the water discharge from the water discharge port 540W will stop, and body washing | cleaning will be complete | finished (step S218). By performing the body cleaning in this order, the second support portion 536 and the water discharge portion 538 can be cleaned evenly, and the cleaning nozzle before use can be cleaned.

  Subsequently, water is ejected from the water outlet 538W provided at the tip of the water discharger 538 toward the user's “buttock” or the like (step S220). In this way, the user's “wet” or the like can be cleaned by a clean cleaning nozzle that has been pre-cleaned or body-cleaned.

  When the user instructs to stop “human body cleaning” by operating the switch (step S222), water discharge from the water outlet 538W is stopped (step S224), and body cleaning of the second support portion 536 and the water discharge portion 538 is started (step S224). Step S226). That is, while the water W is jetted from the water discharge port 540W of the nozzle cleaning chamber 540, the second support part 536 is retracted into the first support part 534 as shown by the arrow B as shown in FIG. (Step S228). In this way, the second support portion 536 can be cleaned from its root toward the tip.

  Subsequently, with the water W being jetted from the water discharge port 540W, the water discharge portion 538 is retracted into the second support portion 536 as shown by the arrow B as shown in FIG. 12B (step S230). ). Thus, the water discharge part 538 can be wash | cleaned toward the front-end | tip from the root. When the water discharger 538 is completely retracted into the first support part 534, water discharge from the water discharge port 540W is stopped, and the trunk cleaning is finished (step S232).

  By performing the body cleaning in this order, the second support part 536 and the water discharge part 538 can be cleaned evenly, and the dirt attached when the user's “buttock” and the like are cleaned is removed, and after use. The cleaning nozzle can be cleaned.

  Subsequently, as shown in FIG. 13A, post-cleaning is performed (step S234). That is, the water W is ejected from the water outlet 538W of the water discharger 538. At this time, since the water outlet 538W is in the nozzle cleaning chamber 540 as in the pre-cleaning, the inside of the nozzle cleaning chamber 540 and the tip of the water discharge portion 538 are cleaned by ejecting water W. Can do. Also in this case, since the nozzle cleaning chamber 540 protrudes into the bowl 310, the post-cleaning waste water D3 can be dropped into the bowl 310 as it is.

  When the user stands up from the toilet seat 410, the seating sensor is not detected (step S236), and the first support portion 534 is retracted into the sanitary washing toilet seat apparatus body 500 (step S238). Then, as shown in FIG. 13B, the cleaning nozzle 530 is accommodated in the sanitary cleaning toilet seat apparatus body 500 and returns to the standby state (step S240).

As described above, also in this specific example, the waste water for pre-cleaning and body cleaning can be dropped into the bowl 310 as it is by detecting the seating of the user and moving the nozzle cleaning chamber 540 into the bowl 310. it can.
Furthermore, since the washing chamber 540 automatically advances to the bowl 310 upon detection of seating, when the user operates the “human body washing” switch, the water discharge part 538 and the second support part 536 advance in this order and the trunk. Cleaning can be completed and water discharge from the water outlet 538W can be started immediately. As a result, even when a three-stage cleaning nozzle is used, it is possible to reduce the waiting time from when the switch is operated until the water discharge is started, and to obtain comfortable operability.

FIG. 15 is a flowchart showing a modified example of the operation of the three-stage cleaning nozzle described above. In this figure, the same operations as those described above with reference to FIGS. 10 to 14 are denoted by the same reference numerals, and detailed description thereof is omitted.
Also in this modified example, when the seating of the user is detected (step S204), the cleaning chamber 540 automatically advances to the bowl 310 (step S206). However, in this modified example, after the user operates the “human body cleaning” switch (step S210), “pre-cleaning” is performed (step S208).

  According to this modification, for example, when the user stands up from the toilet seat 410 without performing cleaning such as “wet” using the cleaning nozzle 530, “pre-cleaning” is not performed, so water or power Etc. can be saved.

  Also, in this modified example, since the seating is detected and the cleaning chamber 540 automatically advances to the bowl 310, when the user operates the “human body cleaning” switch, the pre-cleaning is performed immediately, and the water discharger 538 and The second support portion 536 advances in this order to complete the body cleaning, and water discharge from the water discharge port 538W can be started. That is, compared with the specific example described above with reference to FIG. 14, the pre-cleaning time is increased, but even when a three-stage cleaning nozzle is used, the waiting time until the water discharge is started after the switch operation is reduced. Comfortable operability can be obtained.

FIG. 16 is a flowchart showing a second modification of the operation of the three-stage cleaning nozzle. Also in this figure, the same operations as those described above with reference to FIGS. 10 to 14 are denoted by the same reference numerals, and detailed description thereof is omitted.
Also in this modified example, when the seating of the user is detected (step S204), the nozzle cleaning chamber 540 automatically advances to the bowl 310 (step S206), and pre-cleaning is executed (step S208). However, in this modified example, after that, the nozzle cleaning chamber 540 is once retracted and stored in the sanitary cleaning toilet seat apparatus body 500 (step S209).

  Thereafter, when the user performs a “human body cleaning” switch operation (step S210), the nozzle cleaning chamber 540 again moves into the bowl 310 (step S211), and the body cleaning starts (step S212).

  Also in this modified example, the seat cleaning is detected and the nozzle cleaning chamber 540 automatically advances to the bowl 310 to perform the pre-cleaning, so that the pre-cleaning can be performed while dropping the waste water into the bowl 310 as it is. After that, the nozzle cleaning chamber 540 is once accommodated (step S209), so that, for example, when the user is used for small or large use, the water splashing of the bowl 310 is applied to the cleaning nozzle 530. Can be prevented.

  In this modified example, when the user operates the “human body cleaning” switch, the nozzle cleaning chamber 540 is advanced (step S211), and the water discharger 538 and the second supporter 536 are advanced in this order to perform body cleaning. The water discharge from the water discharge port 538W can be started. That is, compared with the specific example described above with reference to FIG. 14, although the time for advancement of the nozzle cleaning chamber 540 increases, even when a three-stage cleaning nozzle is used, the time from the switch operation to the start of water discharge The waiting time can be reduced and comfortable operability can be obtained.

  Although specific examples of the operation of the three-stage cleaning nozzle are shown in FIGS. 9 to 16, the present invention can be similarly applied to a four-stage or more multi-stage cleaning nozzle. In that case, two or more support parts are supported between the first support part 534 and the water discharge part 538 described above with reference to FIGS. When the body is cleaned before the human body cleaning, all the support portions can be cleaned in the nozzle cleaning chamber 540 by advancing sequentially from the two or more support portions closer to the water discharge portion 538. Similarly, at the time of body cleaning after human body cleaning, it is possible to clean all the support portions in the nozzle cleaning chamber 540 by retreating sequentially from those far from the water discharge portion 538.

  FIG. 17 is a schematic cross-sectional view illustrating a specific structure of a three-stage cleaning nozzle. 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 provided in the first support portion so as to be movable back and forth, and a second support. And a water discharger 538 provided in the unit so as to freely advance and retract. 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.

  A nozzle cleaning chamber 540 is formed near the tip of the first support portion 534. The first support portion 534 is provided with a water channel 534T, and the water channel 534T communicates with a water discharge port 540W opened inward in the nozzle cleaning chamber 540. A water supply tube 533 is connected to the water channel 534T, and by discharging water inward from the water discharge port 540W, it is possible to clean the second support portion 536, the tip portion of the water discharge portion 538, the body portion, and the like.

As shown in FIG. 17A, the cleaning nozzle 530 is housed in the second support portion 536 except for the tip thereof, and the second support portion 536 is the first support in the housed state. The first support portion 534 is accommodated in the portion 534 and is in a position retracted backward on the mounting base 532. As described above, the cleaning nozzle 530 has a three-stage structure, so that it can be stored compactly.
In addition, a notch 534C is provided on the lower side of the first support portion 534 from the rear end of the first support portion 534 toward the front, and the water supply tube 537 can be inserted into the notch 534C. The water discharger 538 can be moved with a long stroke while shortening the overall length.

  In such a three-stage cleaning nozzle, the user's seating is detected as described above with reference to FIGS. 9 to 16 so that the nozzle cleaning chamber 540 automatically protrudes from the sanitary cleaning toilet seat apparatus body 500. By doing so, it is possible to reduce the waiting time from when the switch is operated to when water discharge is started, and to obtain comfortable operability.

FIG. 18 is a schematic diagram illustrating a modified example of the drive mechanism that advances the nozzle cleaning chamber 540.
That is, FIG. 18A shows a state where the nozzle cleaning chamber 540 is housed in the sanitary washing toilet seat apparatus body 500, and FIG. 18B shows a state where the nozzle cleaning chamber 540 has advanced into the bowl 310. As described above, the mounting base 532 is movable back and forth, and the nozzle cleaning chamber 540 may be advanced from the sanitary cleaning toilet seat apparatus body 500 by moving the mounting base 532 forward as indicated by the arrow C. .

  FIG. 19 is a schematic view illustrating the advance operation of the cleaning nozzle of this example. That is, after the nozzle cleaning chamber 540 fixed to the mounting base 532 via the first support portion 534 advances to the bowl 310 by moving the mounting base 532 forward, it is shown in FIG. As described above, the operation described above with reference to FIGS. 9 to 16 can be performed by the water discharger 538 having advanced and the second support 536 having advanced.

FIG. 20 is a perspective view illustrating a specific example of the sanitary washing toilet seat device according to the present embodiment.
In this specific example, the sanitary washing toilet seat apparatus body 500 is installed on a flat surface at the upper rear of the flush toilet stool 300, and its front surface 510 is curved so as not to cover the rear part of the bowl 310 of the stool toilet 300. The curved front surface 510 is provided with an opening 520 for inserting and removing a cleaning nozzle for cleaning the “wet”. The opening 520 is provided with a closing plate 525, and the cleaning nozzle is accommodated on the back side of the closing plate 525.

  When the sanitary washing toilet seat apparatus main body 500 is extended on the bowl 310, it becomes easy to get “bounce” or the like of the accumulated water in the bowl 310 on the back side, and it becomes easy to get dirty. Moreover, the cleaning also takes time.

  On the other hand, in this specific example, the sanitary washing toilet seat apparatus body 500 does not extend to the bowl 310, and the curved front surface 510 forms a curved surface that is substantially integral with the curved side wall surface of the opening of the bowl 310. As a result, it is difficult to get dirty, and it is difficult for small water to be applied to men's small use. In addition, it is possible to save the trouble of removing the sanitary washing toilet seat apparatus body 500 from the sitting toilet 300 at the time of cleaning, and cleaning becomes extremely easy. In addition, the toilet device can be provided with a comfortable and comfortable feeling to use, giving the user a feeling of cleanliness and hygiene with a clean appearance and good appearance.

  According to the present invention, when a user's seating is detected and the nozzle cleaning chamber is advanced from the sanitary cleaning toilet seat apparatus body 500, for example, a three-stage or higher multi-stage cleaning nozzle is mounted. However, a comfortable operability can be obtained by shortening the waiting time until water discharge. In particular, as in this specific example, in order not to extend to the bowl 310, the depth of the sanitary washing toilet seat device body 500 must be reduced, and the washing nozzle also needs to be multi-staged accordingly. There is. Even in such a case, according to the present invention, the waiting time until water discharge can be shortened.

  In addition, according to the present invention, the pre-cleaning, the body cleaning, and the post-cleaning are performed in a state in which the nozzle cleaning chamber has advanced from the sanitary cleaning toilet seat apparatus body 500, so that the waste water from these cleanings can be reliably dropped into the bowl 310. . That is, even if the sanitary washing toilet seat main body 500 does not cover the bowl 310, the problem of drainage does not occur.

  The present invention can be similarly applied to the case where the sanitary washing toilet seat main body 500 extends to the bowl 310. For example, the effect of shortening the waiting time and the drainage of the pre-cleaning or the body cleaning can be reliably performed in the bowl. Effects that can be dropped can be obtained in the same manner.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples. For example, the shape of the first support portion is not limited to the cylinder shape surrounding the second support portion, and may be any shape and structure that can support the second support portion so as to advance and retreat. Similarly, the shape of the second support portion is not limited to the cylinder shape surrounding the water discharge portion, and may be any shape and structure that can support the water discharge portion so that the water discharge portion can be advanced and retracted.
