  As described above, the light emitted from the LED 61 is emitted upward from the opening 70 via the transmission plate 65. The light emitted from the LED 61 is directed from the arrow P (light emitted in the most forward direction of the sanitary washing device 1) to the arrow Q (most rearward of the sanitary washing device 1) with its optical axis directed toward the ceiling of the toilet room. (Light emitted in the direction) is spread through the opening 70 in a range (longitudinal irradiation range of direct light) that extends in the front-rear direction. Thereby, the illuminating device 6 can brighten the upper direction of the casing 3 widely.

  In the state where the toilet lid 5 is opened (5B), the light emitted from the LED 61 (the light indicated by the arrow Q) is reflected on the back surface of the toilet lid 5, so that the reflected light (arrow R) causes the above-described reflection. It is possible to illuminate the front more than the light of the arrow P. Thereby, the range wider than the irradiation range of the direct light mentioned above can be irradiated by reflected light (indirect light) (vertical direction irradiation range of indirect light).

  Thus, in the state (5B) where the toilet lid 5 is opened, the interior of the toilet room 10 is illuminated by both the direct light from the illumination device 6 and the indirect light reflected by the toilet lid 5. In either case, the LED 61 is visible from the outside (not covered by the toilet lid 5), whether the toilet lid 5 is opened (5B) or the toilet lid 5 is closed (5A). However, the light emitted from the LED 61 is emitted from the opening 70 to the outside of the sanitary washing device 1 through the transmission plate 65.

  Next, the irradiation range of the lighting device 6 in the left-right direction (lateral direction) will be described with reference to FIG. FIG. 5 is a cross-sectional view taken along line AA shown in FIG.

  As described above, the opening 70 has a horizontally long rectangular shape. As described above, three LEDs 61 are arranged in a line along the longitudinal direction of the opening 70. Then, the light emitted from the LED 61 is emitted upward from the opening 70 via the transmission plate 65. The light emitted from the LED 61 ranges from the arrow S (light emitted in the leftmost direction) to the horizontal direction of the arrow T (light emitted in the rightmost direction) (the horizontal direction of the direct light). In the irradiation range), the light is emitted through the opening 70. Since the three LEDs 61 are arranged side by side in this way, the lighting device 6 can brighten the upper part of the casing 3 widely in the left-right direction.

  Thereby, the illuminating device 6 can illuminate the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet bowl 2 more effectively.

When the user operates the operation button 21 of the auto light switch 22, the auto light switch 22 is turned “on” (auto light mode “on” state). Specifically, when the user operates the operation button 21 of the auto light switch 22 of the remote control device 20, the remote control operation signal (infrared) is transmitted from the remote control device 20 to the remote control receiving unit 33, and the remote control The operation information of the remote control operation signal (infrared) transmitted from the receiving unit 33 to the control device 30 is stored in the RAM (not shown) of the control device 30 (the “ON” state of the auto light mode is stored). As a result, until the user operates the operation button 21 of the auto light switch 22 of the remote control device 20 and turns the auto light switch 22 to “off”, the auto light switch 22 is turned “on” (auto light mode “on”). "State" is stored in the control means 30. As described later, in the “ON” state of the auto light mode, the human body or the seating is detected by any one of the first human body detection sensor 7, the second human body detection sensor 8, and the seating detection sensor 9. Then, the lighting device 6 is automatically turned on.

  The auto open / close switch 23 is an operation button 21 for determining whether or not to set an automatic open / close operation mode (auto open / close mode). When the user operates the operation button 21 of the auto open / close switch 23, the auto open / close switch 23 is turned on (in the auto open / close mode “on” state). Specifically, when the operation button 21 of the auto open / close switch 23 of the remote control device 20 is operated by the user, the remote control operation signal (infrared) is transmitted from the remote control device 20 to the remote control receiving unit 33, and the remote control The operation information of the remote control operation signal (infrared) transmitted from the receiving unit 33 to the control device 30 is stored in the RAM (not shown) of the control device 30 (the “ON” state of the auto open / close mode is stored). As a result, the operation button 21 of the auto open / close switch 23 of the remote control device 20 is operated by the user, and the auto open / close switch 23 is turned “on” (auto switch on / off in the auto open / close mode) until the auto open / close switch 23 is turned “off”. "State" is stored in the control means 30. As will be described later, in the “ON” state of the automatic open / close mode, when the human body is detected by the first human body detection sensor 7, the toilet lid 5 is gently opened, and the first human body detection sensor 7, the second human body detection sensor 7, and the second human body detection sensor 7. When the human body detection sensor 8 no longer detects a human body, the toilet lid 5 is gently closed after a predetermined time (if the toilet seat 4 is opened, it is closed together with the toilet seat 4). Details will be described later.

  Next, the switching operation of the illumination device 6 shown in FIG. 2 will be described with reference to FIG. FIG. 7 is a state transition diagram of the switching operation of the illumination device shown in FIG.

  In FIG. 7, a series of operations from the state before the user enters the toilet room 10 (standby state) to entering the toilet room 10, sitting on the toilet seat 4, and leaving the toilet room 10 will be described. ing. In FIG. 7, information from various programs and various sensors is transmitted to the control device 30, and the control device 30 changes the light amount of the illumination device 6 from the “light-off” state to the “low level”, “medium ( The lighting state is switched in three stages, “Middle level” and “High level”.

  In the present embodiment, the lighting state is switched in three stages from “light off” to “light level”, “middle level”, and “high level”. However, the present invention is not limited to this, and “bottom level” may be provided in addition to “low level”, “middle level”, and “high level”. Steps (eg, “Low 1 Level”, “Low 2 Level”, “Low 3 Level”, etc.) may be provided in “Low Level”, “Middle Level”, “High Level”, etc. . That is, the intermediate light amount (the light amount of S2 (in this embodiment, “middle level”)) is a light amount that does not make the user of the toilet room 10 feel dazzled and awaken even at night use. As will be described later, as long as the light quantity increases in the order of S3 → S2 → S5, the magnitude of each light quantity does not matter.

(State of S1)
First, the state of S <b> 1 indicates a state (standby state) before a person enters the toilet room 10. In this standby state, since there is no user in the toilet room 10, the lighting device 6 in the toilet room 10 is turned off.

  In the standby state, the auto light mode is set to “ON”. That is, in this standby state, the first human body detection sensor 7 (pyroelectric infrared sensor), the second human body detection sensor 8 (photoelectric infrared sensor), and the seating detection sensor 9 (photoelectric infrared sensor). When a human body or seating is detected by any sensor, the lighting device 6 is automatically turned on.

  In this state of S1, when a user enters the toilet room 10 and the person who enters the room is detected by the first human body detection sensor 7, the second human body detection sensor 8 also detects the front of the sanitary washing device 1. When a person in the vicinity is detected (human body detection sensor (first or second): detection), the state shifts to the state of S2 (M lighting state).

  Here, even when a person in the vicinity of the front of the sanitary washing device 1 is detected by the second human body detection sensor 8, the user moves to the state of S <b> 2 in the vicinity of the front of the sanitary washing device 1. Thus, it is assumed that the operation button 21 of the auto light switch 22 of the remote control device 20 is operated to change the auto light switch 22 from “off” to “on”. However, in the present embodiment, since the auto light switch 22 is “ON” in the standby state, when the user enters the toilet room 10, the person is detected by the first human body detection sensor 7, and S2 Migrate to

  As described above, the “ON” state of the auto light mode continues unless the user operates the operation button 21 of the auto light switch 22 of the remote control device 20 to turn the auto light switch 22 “OFF”. .

  Further, when the automatic opening / closing mode is in the “ON” state in the state of S1, when the user enters the toilet room 10 and the person who enters the room is detected by the first human body detection sensor 7, The toilet lid 5 automatically opens. Thereby, the user does not need to open the toilet lid 5 manually and can simplify the use. Moreover, when the toilet lid 2 is opened, the second human body detection sensor 8 becomes visible, and the second human body detection sensor 8 becomes detectable.

(State of S1 → State of S2)
As described above, when the user enters the toilet room 10 and the person who has entered the room is detected by the first human body detection sensor 7, the process proceeds from the state of S1 to the second state. Thus, since the lighting device 6 is automatically turned on when entering the toilet room 10, the user does not need to turn on the lighting device 6 manually (simplification of use of the toilet room 10). Moreover, compared with the case where it always lights, the electricity bill of the illuminating device 6 can also be saved.

The state of S2 indicates a state where the lighting device 6 is lit at a middle level (M lighting state). In the state of S2, the inside of the toilet room 10 is illuminated to such an extent that it is sufficiently lit (M lighted) to be sufficiently useful as illumination of the toilet room 10. In other words, in this M lighting state, even when a person standing at the tip of the toilet seat 4 looks at the illumination device 6 from the position, the brightness is set so that the user does not feel glare (brightness). 350 cd / m ² or less). Specifically, by supplying a current of 10 mA to the three LEDs 61, the brightness when the person standing at the tip of the toilet seat 4 sees the illumination device 6 from the position becomes 350 cd / m ² or less. Is set to

Thereby, when a person standing at the front end of the toilet seat 4 looks at the lighting device 6 from the position, the brightness of the lighting device 6 is set to be 350 cd / m ² or less. Not only the person who entered the room 10, but also when standing in front of the sanitary washing device 1 as in a men's urine, the user of the toilet room 10 does not feel glare and the user of the toilet room 10 at night There is no awakening.

  As described above, when a user enters the toilet room 10, the first person detection sensor 7 detects a person who has entered the toilet room 10. When the user comes near the front of the sanitary washing device 1, the second human body detection sensor 8 also detects a person near the front of the sanitary washing device 1. Thus, when the user comes near the front of the sanitary washing device 1, the person is detected by the second human body detection sensor 8 while being detected by the first human body detection sensor 7. Therefore, in the present embodiment, if a human body is detected by the second human body detection sensor 8 while the human body is detected by the first human body detection sensor 7, the detection signal of the first human body detection sensor 7 is used. The information is not transmitted to the control unit 30. Thereby, the control signal for controlling the illuminating device 6 is unified, and the system configuration can be simplified.

(State of S2 → State of S5)
When the user is seated on the toilet seat 4 in the state of S2, and the seating on the toilet seat 4 is detected by the seating detection sensor 9, the process proceeds to S5 (H lighting state). That is, when the user is seated on the toilet seat 4 as in the use of a girl or the boy's stool, the seating on the toilet seat 4 is detected by the seating detection sensor 9, and the process proceeds to S5 (H lighting state).

  The state of S5 indicates a state where the lighting device 6 is lit at a high level (H lighting state). In the state of S5, the remote control device 20 can be recognized by the lighting device 6 to such an extent that the operation button 21 of the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet bowl 2 can be recognized with the user seated on the toilet seat 4. Is illuminated by In other words, in the H lighting state, the illuminance is set so that the operation button 21 of the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet bowl 2 can be recognized (the illuminance (brightness) is set to 0.1 Lx or more. ) Specifically, the illuminance of the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet bowl 2 is set to be 0.1 Lx or more by supplying a current of 20 mA to the three LEDs 61. .

  In the present embodiment, the illuminance of the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet bowl 2 is set to 0.1 Lx or more by supplying a current of 20 mA to the three LEDs 61 in the H lighting state. However, the present invention is not limited to this, and it is installed on the wall surface of the toilet room 10 next to the toilet 2 by energizing the three LEDs 61 with a current of 20 mA or more (for example, 30 mA, 40 mA, 50 mA, etc.). The illuminance of the remote control device 20 to be set may be set to 0.1 Lx or more.

  Since the lighting device 6 is provided between the toilet seat rotating shaft 14 and the toilet lid rotating shaft 15 at the upper part of the casing 3, a space is secured between the back surface of the seated user and the toilet lid 5. . For this reason, the illuminating device 6 can illuminate the wall surface of the toilet room 10 beside the toilet bowl 2 using the space secured between the back surface of the seated user and the toilet lid 6. Moreover, when the user is seated on the toilet seat 4, the lighting device 6 is in the H-lit state, so that when the user is seated, the user is installed on the wall surface of the toilet room 10 next to the toilet 2. The operation button 21 of the remote control device 20 can be recognized, and the operation button 21 can be operated reliably. In particular, since the lighting device 6 is provided in the vicinity of the toilet lid rotating shaft 14 at the upper part of the casing 3, a wide space is secured between the back surface of the seated user and the lighting device 6. For this reason, the illuminating device 6 can illuminate the wall surface of the toilet room 10 beside the toilet 2 further forward using the space secured between the back surface of the seated user and the illuminating device 6. Further, when the user is seated on the toilet seat 4, the lighting device 6 is positioned behind the user seated on the toilet seat 4. The light of the device 6 does not directly enter the eye and the user does not wake up.

  As described above, even when the toilet room 10 is used at night, the user is not prompted to wake up, and the operation button 21 of the remote control device 20 installed on the wall surface of the toilet room 10 beside the toilet 2 can be surely pressed. The illumination device 6 can be realized by a single illumination device 6.

When the user is seated on the toilet seat 4 in the state of S1 (standby state) and seating on the toilet seat 4 is detected by the seating detection sensor 9, the process proceeds to S5 (H lighting state).
Here, when the user is seated on the toilet seat 4 in the state of S1 (standby state) and the seating detection sensor 9 detects that the user is seated on the toilet seat 4, it is assumed that the user shifts to the state of S5. However, it is assumed that the operator operates the operation button 21 of the auto light switch 22 of the remote control device 20 while sitting on the toilet seat 4 to change the auto light switch 22 from “off” to “on”. In this embodiment, since the auto light switch 22 is “ON” in the standby state, the process does not shift from S1 to S5.

(State of S5 → State of S2)
When the user leaves the toilet seat 4 in the state of S5 and the seating on the toilet seat 4 is not detected by the seating detection sensor 9, the process proceeds to S2 (M lighting state). That is, when the user leaves the toilet seat 4, the user is in the vicinity of the front of the sanitary washing device 1, so that a person in the vicinity of the sanitary washing device 1 is detected by the second human body detection sensor 8, and S2 (M lighting state).
Thereby, since the light quantity of the illuminating device 6 is shifted from the H lit state to the M lit state, even when the user who has left the toilet seat 4 sees the illuminating device 6 from the position where he has been separated, the glare is reduced. The user of the toilet room 10 at night is not awakened.

(State of S2 → State of S3)
When the user is no longer near the front of the sanitary washing device 1 in the state of S2 (the second human body detection sensor 8 is not detected), the process proceeds to S3 (L lighting waiting state).

  The state of S3 indicates a state in which the user shifts from S3 to S4 after elapse of a predetermined time (90 seconds) after the user leaves the front vicinity of the sanitary washing device 1 while continuing the M lighting state (L Lighting state). That is, in the state of S3, when a predetermined time (90 seconds) elapses after the user leaves the vicinity of the front of the sanitary washing device 1 (no longer using the sanitary washing device 1), the user leaves the toilet room 10 It is assumed that the user will leave the room, and after that time (90 seconds) has elapsed, the process proceeds from S3 to S4. Specifically, in the state of S3, a person in the vicinity of the front of the sanitary washing device 1 is not detected by the second human body detection sensor 8 in the state of S2, and the control unit 30 receives the signal from the second human body detection sensor 8. If the detection signal is not received, the control device 30 sets a timer (not shown). Then, when a person in front of the sanitary washing device 1 is not detected by the second human body detection sensor 8 within a predetermined time (90 seconds) after the timer is set, the process proceeds to the state of S4. Thereby, the lighting device 6 changes from M lighting to L lighting (the lighting device 6 lights at a low level). The predetermined time (90 seconds) is set to a time sufficient for the user to repair or wash his hands after using the sanitary washing device 1. In this embodiment, 90 seconds are set.

  In addition, if a person near the front of the sanitary washing device 1 is detected by the second human body detection sensor 8 before a predetermined time (90 seconds) has elapsed since the timer was set, the process proceeds to the state of S2. . And if it transfers to S2, the 90 second timer will be reset by the control apparatus 30. FIG. And when the user who returned to the front vicinity of the sanitary washing apparatus 1 leaves | separates from the front vicinity of the sanitary washing apparatus 1 again, the state of the illuminating device 6 is again shifted from S2 to S3, and the timer for 90 seconds is controlled. It is set again by means 30.

  Thereby, the timing for shifting from the M lighting state to the L lighting state is set as a starting point when there is no person near the front of the sanitary washing device 1, that is, when the user stops using the sanitary washing device 1. Therefore, when the user stops using the sanitary washing device 1, the number of minutes after which the user leaves the room is obtained in advance (normal value, etc.), and after the time has elapsed, the M lighting state is changed to the L lighting state. It is possible to shift from the M lighting state to the L lighting state after the actual time has elapsed.

(S3 state → S4 state)
In the state of S3, the state in which the person near the front of the sanitary washing device 1 is not detected by the second human body detection sensor 8 continues for a predetermined time (90 seconds), so that the state transitions to the state of S4.

  In the state of S4, the lighting device 6 changes from M lighting to L lighting, and a state where a person near the front of the sanitary washing device 1 is not detected by the second human body detection sensor 8 further continues for a predetermined time (5 seconds). A state of transition from S4 to S1 is shown (waiting for turning off). That is, when a predetermined time (5 seconds) elapses after the lighting device 6 is turned on, it is considered that there is no person in the toilet room 10, and the process proceeds from S4 to S1 after the time (5 seconds) elapses. Specifically, in the state of S4, the person in the vicinity of the front of the sanitary washing device 1 in the state of S3 is not continuously detected by the second human body detection sensor 8 for 90 seconds, and the control means 30 is in the second state. If the detection signal from the human body detection sensor 8 is not received continuously for 90 seconds, a timer (not shown) is set by the control device 30. Then, if the user is not detected by the first human body detection sensor 7 and the second human body detection sensor 8 within a predetermined time (5 seconds) after the timer is set, the state is shifted to S1. The Thereby, the illuminating device 6 turns off from L lighting. During this predetermined time (5 seconds), the user notices that the lighting device 6 will soon be turned off as the light intensity is further reduced from M lighting to L lighting (light-off notice). A sufficient time is set as a time for taking an action to be detected by the human body detection sensor 7 and the second human body detection sensor 8. In this embodiment, 5 seconds is set.

  If the user is detected by the first human body detection sensor 7 and the second human body detection sensor 8 before a predetermined time (5 seconds) has elapsed since the timer was set, the state of S2 It is transferred to. Thereby, the illuminating device 6 will be in M lighting state. And if it transfers to S2, the timer for 5 seconds will be reset by the control apparatus 30. FIG.

  Also, in the state of S4, when the auto open / close mode is in the “ON” state, as in the lighting device 6, the first human body detection is performed within a predetermined time (5 seconds) after the timer is set. When the user is not detected by the sensor 7 or the second human body detection sensor 8, the toilet lid 5 is gently closed. This eliminates the need for the user to manually close the toilet lid 5 and simplifies use.

  In any of the above-described S2 (M lighting state), S5 (H lighting state), S3 (L lighting state), and S4 (lighting waiting state), the operation button 21 of the auto light switch 22 of the remote control device 20 is operated. If the auto light switch 22 is turned off, the process proceeds to S6 (stop state). In the stop state, the lighting device 6 is turned off regardless of whether the first human body detection sensor 7, the second human body detection sensor 8, and the seating detection sensor 9 are detecting. That is, in the stopped state, the lighting device 6 is not automatically turned on, but the lighting device 6 is turned on by manually operating an operation switch (not shown) of the lighting device 6.

  In addition, not only when the illumination device 6 is in S1 (standby state) and S2 (M lighting state), but also in the state of either S3 or S4, the seating detection sensor 9 allows the user to sit down. Is detected, the process proceeds to S5 (H lighting state). That is, when the auto light mode is “ON”, when sitting on the toilet seat 4 is detected, the process proceeds to the state of S5, and the lighting device 6 is turned on.

  As described above, in the sanitary washing device 1 of the present embodiment, the toilet room 10 is illuminated with a light amount that does not cause the user who enters the toilet room 10 at night to feel dazzling (states S2 and S3). ), When the user takes a posture (sitting) that does not directly see the light of the lighting device 6, the light amount of the lighting device 6 is increased and the user sitting on the toilet seat 4 makes the remote control device 20 Is illuminated with brightness that can be operated (state of S5). That is, in the sanitary washing device 1 of the present embodiment, even when the toilet room 10 is used at night, the light of the lighting device 6 does not prompt the user to wake up, and the toilet room 10 near the toilet 2 It is configured to enhance the operability of the remote control device 20 installed on the wall surface (one of the left and right wall surfaces).

  Further, when the user enters the toilet room 10, the lighting device 6 is automatically turned on when the user is detected by the first human body detection sensor 7. Therefore, it is necessary to turn on the lighting device 6 manually. The use of the toilet room 10 can be simplified.

  In addition, even after the user leaves the vicinity of the front of the sanitary washing device 1, the toilet room 10 is illuminated for a certain period of time in anticipation of the time required for hand washing or the like (in the state of S3). Can be washed in the illuminated toilet room 10 and no one is in the vicinity of the front of the sanitary washing device 1 (the second human body detection sensor 8 is no longer detected). ) Since the lighting device 6 is turned off after a lapse of a predetermined time, the time required for a user's hand washing or the like (a normal value or the like) is obtained in advance, and the lighting device 6 is turned off after the lapse of time. The illumination device 6 can be turned off after a certain time has elapsed. Further, before the lighting device 6 is turned off, the light amount of the lighting device 6 is further reduced to notify the user that the lighting device 6 is turned off (preliminary notice) (state of S4). Even if it is necessary, the user can know in advance that the lighting device 6 will soon be turned off, and can turn on the lighting device 6 again at that time (the state of S4 → the state of S2). Status).

  Next, operation | movement of the illuminating device 6 corresponding to each usage condition of the toilet room 10 is demonstrated using FIGS. 8-11. 8 to 11 are timing charts of the lighting device 6 corresponding to the usage mode of the toilet room 10. In this time chart, the auto light mode is set to “ON” in the standby state as in the state transition diagram of FIG. Moreover, each state (S1-S6) of the illuminating device 6 has shown the state of the illuminating device 6 of the state transition diagram of FIG.

(Women's use or boy's stool)
First, the lighting state of the lighting device 6 when the user sits on the toilet seat 4 after entering the toilet room 10 will be described with reference to FIG. FIG. 8 is a time chart showing the state of the lighting device when the user sits on the toilet seat after entering the toilet room.

  When the user enters the toilet room 10, it is detected by the first human body detection sensor 7 that the user has entered the room (time ta1). If it does so, the state of the illuminating device 6 will transfer to the state of S2 from the state of S1. Thereby, the illuminating device 6 lights M. At the same time, when the automatic opening / closing mode is “ON”, the toilet lid 5 starts to open slowly. And if a user advances to the sanitary washing apparatus 1 (toilet bowl 2) vicinity, the 2nd human body detection sensor 8 will be in an ON state (detection state) (time ta2). If the 2nd human body detection sensor 8 will be in an ON state (detection state), the 1st human body detection sensor 7 will be in an OFF state (non-detection state). In this state, since the second human body detection sensor 8 is in the on state (detection state), the M lighting state (S2) is maintained.

  Thereafter, when the user sits on the toilet seat 4, the seating detection sensor 9 detects this, and the state of the lighting device 6 shifts from S <b> 2 to S <b> 5. As a result, the lighting device 6 that has been turned on M is turned on H (time ta3). When the user finishes using the sanitary washing device 1 and leaves the toilet seat 4, the seating detection sensor 9 does not detect the seating. As a result, the state of the lighting device 6 shifts from S5 to S2, and the lighting device 6 that has been H-lighted is M-lighted (time ta4).

After that, when the user who has left the seat leaves the vicinity of the front of the sanitary washing device 1, the second human body detection sensor 8 does not detect the user (time ta5). As a result, the state of the illumination device 6 moves from S2 to S3, and a 90-second timer is set. The user moves to the hand washing place 11 (time ta6), and after hand washing, leaves the toilet room 10 (time ta7).
As shown in FIG. 8, when the user leaves before the timer notifies the control device 30 that 90 seconds have elapsed, after the user leaves (time ta7), the state of the lighting device 6 changes from S3. The process proceeds to S4, where the lighting device 6 that has been lit M is changed to L lighting (time ta8).

  Thereafter, after the elapse of 5 seconds, the state of the lighting device 6 shifts from S4 to S1, and thereby the lighting device 6 is turned off (time ta9). At the same time, the toilet lid 5 starts to close slowly by the function of the automatic opening / closing mode.

(For example, for men's piss)
Next, an illumination state of the illumination device 6 when the user uses the toilet room 10 without being seated on the toilet seat 4 (for example, during men's urination) will be described with reference to FIG. FIG. 9 is a time chart showing the state of the lighting device when the user uses the urinal without entering the toilet seat (when men's urination) after entering the toilet room. Since the time from when the user enters the toilet room 10 to the vicinity of the front of the sanitary washing apparatus 1 (time tb1 to time tb2) is the same as that in FIG. A description will be given from the time of arrival in the vicinity of the device 1. In a state where it arrives in the vicinity of the front of the sanitary washing device 1, the second human body detection sensor 8 is in an on state (detection state), and the lighting device 8 is lit M.

  The user who arrives in the vicinity of the sanitary washing device 1 uses the sanitary washing device 1 directly or manually by operating the remote control device 20 to open the toilet seat 4 (time tb21).

  When the user leaves the front vicinity of the sanitary washing apparatus 1 after using the sanitary washing apparatus 1, the user is not detected by the second human body detection sensor 8 (time tb5). Thereafter, after the same operation (time tb5 to time tb9) as in FIG. 8 is performed, the illumination device 6 is turned off (time tb9). As soon as the lighting device 6 is turned off, the opened toilet lid 5 together with the toilet seat 4 starts to be closed slowly by the function of the automatic opening / closing mode.

(Use for more than 90 seconds (when using girls or using men's stool))
Next, the lighting state of the lighting device 6 in the case where the user has been in the toilet room 10 for more than 90 seconds after using the sanitary washing device 1 will be described with reference to FIG. FIG. 10 is a time chart showing the state of the lighting device when the user has been in the toilet room for more than 90 seconds after using the sanitary washing device. Since the time from when the user enters the toilet room 10 until the user leaves the vicinity of the front of the sanitary washing device 1 (time tc1 to time tc6) is the same as that in FIG. A description will be given starting from the vicinity of 1. In a state away from the vicinity of the front of the sanitary washing device 1, the second human body detection sensor 8 is in an on state (detection state), and the lighting device 8 is lit M.

  When the user leaves the toilet seat 4 and the user leaves the vicinity of the front of the sanitary washing device 1, the second human body detection sensor 8 does not detect the user (time tc5). As a result, the state of the lighting device 6 shifts from S2 to S3, and a 90-second timer is set. When the user moves to the hand washing place 11 (time tc6) and performs hand washing or the like in the hand washing place 11 for a long time, when the timer notifies the controller 30 that 90 seconds have passed, the state of the lighting device 6 is changed. The process proceeds from S3 to S4. Accordingly, the lighting device 6 that has been turned on M is turned on L (time tc8). Thereafter, when the user in the toilet room 10 moves his / her foot to change the standing position, the user's movement is detected by the first human body detection sensor 7 (time tc10). As a result, the state of the illumination device 6 shifts from S4 to S2. Accordingly, the lighting device 6 starts M lighting. Moreover, in the state which shifted to S2, since the user is not in the vicinity of the sanitary washing apparatus 1, it is not detected by the second human body detection sensor 8, and the second human body detection sensor 8 is in an off state (non-detection state). Thus, the process proceeds from S2 to S3, and the 90-second timer is set again.

  Then, before the timer reaches 90 seconds, the user leaves the hand washing place 11 and leaves the toilet room 10 (time tc11). Thereafter, when the controller is notified that 90 seconds have passed when the timer has passed 90 seconds, the process proceeds from S3 to S4 (time tc12), and after 5 seconds have passed, the process proceeds from S4 to S1. The lighting device 6 is turned off (time tc13).

(Toilet lid manual closing)
Next, the illumination state of the illumination device 6 when the user leaves the toilet seat 4 and manually closes the toilet lid 5 will be described. FIG. 11 is a time chart showing the state of the lighting device when the toilet lid 5 is manually closed after using the sanitary washing device. Since the time from when the user enters the toilet room 10 to the time when the user leaves the toilet seat 4 (time td1 to time td4) is the same as in FIG. 8, the user has left the toilet seat 4 here. I will explain from time to time. In a state where the user is separated from the toilet seat 4, the second human body detection sensor 8 is in an on state (detection state), and the lighting device 8 is lit M.

  When the user leaves the toilet seat 4 and the toilet lid 5 is manually closed (time td22), the second human body detection sensor 8 becomes invisible, so the second human body detection sensor 8 is turned off. (Non-detection state). Thereby, since the 2nd human body detection sensor 8 stops detecting a human body, the state of the illuminating device 6 transfers to S3 from S2. Then, a 90-second timer is set (time td22).

  Thereafter, the user passes the hand washing place 11 (time td6), and before the timer elapses 90 seconds, the user leaves the hand washing place 11 and leaves the toilet room 10 (time td7). Thereafter, when the timer notifies the control device 30 that 90 seconds have elapsed, the state of the lighting device 6 shifts from S3 to S4 (time td8), and after waiting for another 5 seconds, shifts from S4 to S1 (time td9). ).

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

Hereinafter, modifications of the present invention will be described.
(1) In this embodiment, the illuminating device 6 is provided in the vicinity of the toilet lid rotating shaft 15 in the upper part of the casing 3. However, the present invention is not limited to this, and the illuminating device 6 is separated from the vicinity of the toilet lid rotating shaft 15. The toilet seat rotating shaft 14 and the toilet lid rotating shaft 15 may be provided. In this case, for example, even when the toilet lid 5 is closed, the illuminating device 6 can be visually recognized from the outside (for example, a cutout or a window is provided on the illuminating device 6). The interior of the toilet room 10 can be illuminated whether the lid 5 is open or closed. Even when the illuminating device 6 is provided between the toilet seat rotating shaft 14 and the toilet lid rotating shaft 15 apart from the vicinity of the toilet lid rotating shaft 15, the toilet seat 4 is in a state where the user is seated on the toilet seat 4. The remote controller 20 can be illuminated using the space between the back of the user seated on the toilet and the toilet lid 5.

  (2) In the present embodiment, the lighting device 6 has three light levels of L, M, and H. However, the present invention is not limited to this, and includes three levels of light: L, M, and H. A plurality of groups may be provided, and a group desired by the user may be selected using, for example, the remote control device 20 from a group composed of light amounts of three levels of L lighting, M lighting, and H lighting. . Thereby, a light quantity can be changed with a user's own liking. For example, three types of dimming mode, normal mode, and dimming mode are provided, and each of the dimming mode, normal mode, and dimming mode is set by operating the operation button 21 of the remote controller 20. May be selected (default value (initial setting value) is normal mode). In the dimming mode, for example, the current supplied to the LED 61 during L lighting, M lighting, and H lighting is 4 mA, 8 mA, and 18 mA, respectively. In the normal mode, for example, 5 mA, 10 mA, and 20 mA. Also, in the brightening mode, for example, it may be set to 6 mA, 12 mA, and 25 mA.

  (3) In S4 (waiting for turning off) in FIG. 7 of the present embodiment, the lighting device 6 is switched from M lighting to L lighting in order to notify the user that the lights will be turned off after 5 seconds (notice). Not limited to this, the lighting device 6 may be blinked (repeatedly turned on and off) for advance notice. Thus, even if the user does not notice that the amount of light has decreased from M lighting to L lighting, the user can be informed (predicted) that the light will be turned off after 5 seconds.

  (4) In this embodiment, the first human body detection sensor 7 detects a user who has entered the toilet room 10, and the second human body detection sensor 8 detects a user near the front of the sanitary washing device 1. However, the present invention is not limited to this, and only the second human body detection sensor 8 may be provided. In this case, when a user in the vicinity of the front of the sanitary washing device 1 is detected by the second human body detection sensor 8 in S1 of FIG. 7, the process proceeds from S1 to S2, and in S4, the sanitary washing device 1 When the user in the vicinity of the front is detected by the second human body detection sensor 8, the process proceeds from S4 to S2. And in S4, when the user in the front vicinity of the sanitary washing apparatus 1 is not detected for 5 seconds by the 2nd human body detection sensor 8, it will transfer to S1 from S4.

  Thereby, when the person in front of the sanitary washing device 1 is detected by the second human body detection sensor 8, the lighting device 6 is turned on, so that the user uses the sanitary washing device 1 at night. Even when the lighting device 6 is not turned on manually, the position of the sanitary washing device 1 can be recognized and the sanitary washing device 1 can be used. In particular, when a person near the front of the sanitary washing device 1 is detected by the second human body detection sensor 8, an illumination that does not have a large amount of light is turned on. Even when standing (such as when boys are small), there is no glare and no awakening. Furthermore, when the user is seated on the toilet seat 4, the lighting device 6 is located behind the user seated on the toilet seat 4, so that the light from the lighting device 6 does not enter the eyes and is used. One does not awaken. In addition, when the seating detection sensor 9 detects the seating on the toilet seat 4, the light amount of the lighting device 6 is increased, so that the user can install the seating device 10 on the wall of the toilet room 10 next to the toilet 2. Therefore, the operation button 21 of the remote control device 20 can be recognized and the operation button 21 can be operated with certainty.

  Further, only the first human body detection sensor 7 may be provided. In this case, when a user who has entered the toilet room 10 is detected by the first human body detection sensor 7 in S1 of FIG. 7, the process proceeds from S1 to S2, and in S2, the user who has entered the toilet room 10 is used. If the person is not detected by the first human body detection sensor 7, the process proceeds from S2 to S4 (S3 in FIG. 7 is deleted). In S4, when the user who has entered the toilet room 10 is detected by the first human body detection sensor 7, the process proceeds from S4 to S2, and in S4, the user who has entered the toilet room 10 When the first human body detection sensor 7 does not detect for 5 seconds, the process proceeds from S4 to S1.

  Thereby, when the person who entered the toilet room 10 is detected by the first human body detection sensor 7, since the lighting device 6 is turned on, even when the user uses the inside of the toilet room 10 at night, The interior of the toilet room 10 can be used without manually turning on the lighting device 6. In particular, when a person who has entered the toilet room 10 is detected by the first human body detection sensor 7, an illumination that does not have a large amount of light is turned on, so even when the user uses the inside of the toilet room 10 at night, I can't feel it, and I don't wake up. Furthermore, when the user is seated on the toilet seat 4, the lighting device 6 is located behind the user seated on the toilet seat 4, so that the light from the lighting device 6 does not enter the eyes and is used. One does not awaken. In addition, when the seating detection sensor 9 detects the seating on the toilet seat 4, the light amount of the lighting device 6 is increased, so that the user can install the seating device 10 on the wall of the toilet room 10 next to the toilet 2. Therefore, the operation button 21 of the remote control device 20 can be recognized and the operation button 21 can be operated with certainty.

  Moreover, you may have neither the 1st human body detection sensor 7 nor the 2nd human body detection sensor 8. FIG. In this case, when the seating of the user on the toilet seat 4 is detected by the seating detection sensor 9 in S1 of FIG. 7, the process shifts from S1 to S5. In S5, the seating of the user on the toilet seat 4 is seated. If it is not detected by the detection sensor 9, the process proceeds from S5 to S1 (S2 to S4 in FIG. 7 are deleted). Even in this case, when the seating detection sensor 9 detects the seating on the toilet seat 4, the amount of light of the lighting device 6 is increased, so that when the user is seated, the user can use the toilet room 10 next to the toilet 2. The operation button 21 of the remote control device 20 installed on the wall surface can be recognized, and the operation button 21 can be reliably operated.
