At the same time, the water level detection sensor 620 is started to be driven. The drive of the water level detection sensor 620 is continued until the buttocks washing is stopped P7.

When the water level detection sensor 620 detects the upper limit water level at P2, the control unit starts time measurement, and when a predetermined time elapses, the energization of the water stop solenoid valve 514 is stopped to stop the supply of washing water. In the present embodiment, the energization is stopped 2 seconds after the upper limit water level is detected.

At P2 when the upper limit water level is detected, the sub tank 600 and the heat exchanger 700 are basically full, but by continuing the extra supply for 2 seconds, the heat exchanger 700 and the water discharge amount variable means. The water pump 516 is surely filled with the washing water.

As a result, the air in the heat exchanger 700 can be eliminated and the washing water can be surely filled up, so that the heat exchanger 700 can be surely prevented from being emptied and the safety and durability are improved. can do. Further, by reliably supplying the washing water to the water pump 516, which is the means for varying the amount of water discharged, to fill the water state, the water supply function of the water pump 516, which is the means for changing the amount of water discharged, can be reliably activated.

The control unit 130 starts driving the water pump 516, which is a means for varying the amount of water discharged, and operates the flow control valve 517 to clean the bottom of the nozzle unit 820 at P3 when the energization of the water stop solenoid valve 514 is stopped. The supply of wash water to the flow path 835 is started.

By driving the water pump 516, which is a means for varying the amount of water discharged, the water level of the sub tank 600 drops, and at P4 when the water level detection sensor 620 cancels the detection of the upper limit water level, the control unit 130 drives the heat exchanger 700. Start. By detecting a decrease in the water level, it is possible to confirm that the water pump 516, which is a means for varying the amount of water discharged, is operating normally, and to prevent an abnormal temperature rise of the heat exchanger 700 and the like.

The washing water supplied to the butt washing flow path 835 is ejected from the butt washing spout 834. The ejected washing water passes through the ejection opening 844 and reflects off the inner surface of the holding portion 816 provided at the tip of the support portion 810 to clean the outer surface of the nozzle cover 840. This cleaning operation is called pre-cleaning. The pre-cleaning is continued until the time point P5 2 seconds after the hot water temperature of the heat exchanger 700 reaches 25 ° C.

When the pre-cleaning is completed at the time point P5, the control unit 130 starts driving the cleaning nozzle driving unit 860 of the nozzle device 800, and advances the nozzle unit 820 from the storage position to the butt cleaning position. During the movement from the storage position to the butt cleaning position, the flow control valve 517 is switched to supply cleaning water to the nozzle cleaning flow path 839. The cleaning water supplied to the nozzle cleaning flow path 839 is ejected from the nozzle cleaning ejection port 838 into the nozzle cover 840, and the ejected cleaning water is discharged from the drain port 845 to the outside of the nozzle cover 840 after cleaning the inner surface of the nozzle cover 840. Leaked into. During that time, the nozzle portion 820 is warmed by the washing water, and it is possible to prevent the cold water from being ejected and feeling uncomfortable at the time of the buttocks washing performed later.

At P6 when the nozzle unit 820 reaches the buttock cleaning position, the control unit 130 switches the flow control valve 517 and starts supplying cleaning water to the buttock cleaning flow path 835. The washing water supplied to the butt washing flow path 835 is ejected from the butt washing spout 834, passes through the spouting opening 844, and cleans the local part of the user. The operation of washing the buttocks is continued until P11 when the washing stop operation is performed.

While the heat exchanger 700 is being driven, the control unit 130 controls the wash water to a set temperature based on the detection data of the water inlet temperature sensor 630 and the hot water temperature sensor 730.

By continuing to drive the water pump 516, which is a means for varying the amount of water discharged, the water level of the sub tank 600 drops, and when the water level detection sensor 620 detects the lower limit water level, the control unit 130 energizes the water stop solenoid valve 514 at P7. Is started, and energization is continued until P8 when the water level detection sensor 620 detects the upper limit water level.

At the time point P8 when the upper limit water level is detected, the control unit 130 stops the energization of the water stop solenoid valve 514 and starts the time measurement, and then measures the elapsed time until the time point P9 when the water level detection sensor 620 detects the lower limit water level. do. At the time point P9 when the lower limit water level is detected, the control unit 130 calculates the flow rate by calculating the measured elapsed time and the amount of water (65 cc) from the upper limit water level to the lower limit water level. If there is a difference from the flow rate set for each cleaning strength at the end point P10 of the calculation, the output of the water pump 516, which is a means for varying the amount of water discharged, is adjusted to correct the flow rate of the cleaning water.

At P11 when the operation of stopping the cleaning of the operation unit 210 or the remote controller 400 is performed, the energization of the water pump 516 and the heat exchanger 700, which are means for changing the amount of water discharged, is stopped, and the nozzle device 800 is the cleaning nozzle drive unit. The drive of the 860 is started, and the nozzle portion 820 retracts from the butt washing position to the storage position.

When the nozzle unit 820 is retracted to the storage position, the drive of the cleaning nozzle drive unit 860 of the nozzle device 800 is stopped, and the water pump 516 and the heat exchanger 700, which are means for varying the amount of water discharged, are driven again, and the nozzle unit 820 is driven again. After cleaning, the cleaning is started, and at P13 when a predetermined time elapses, the driving of the water pump 516 and the heat exchanger 700, which are means for varying the amount of water discharged, is stopped, and the post-cleaning is completed.

When the cleaning after the nozzle portion 820 is completed, the water stop solenoid valve 514 is re-energized at P13, the cleaning water is supplied to the sub tank 600, and the water stop solenoid valve 51 is detected at the time when the upper limit water level is detected.
The energization of No. 4 is stopped, a series of control of ass cleaning is completed, the sub tank 600 is in the upper limit water level, and the cleaning means is in the standby state.

FIG. 30 is a sanitary cleaning device in a standby state in which the initial use has been performed before, and shows a time chart during normal use when the cleaning operation is performed.

The major difference from the initial use shown in FIG. 29 is that the sub tank 600 is already full at P20 when the cleaning operation is performed, and that the control unit 130 remembers that the initial use was performed. be.

As shown in FIG. 30, at the time point P20 when the cleaning switch (for example, ass cleaning switch 221 or 410) of the operation unit 210 or the remote controller 400 is operated while the sub tank 600 is in the standby state in a full water state, the control unit 130 , The energization of the water stop solenoid valve 514 is started to start the supply of the washing water, and the energization of the heat exchanger 700 is started at the same time based on the stored data in which the control of the initial operation has already been performed. In addition, the pre-cleaning operation of the nozzle device 800 is started at the same time. In addition, the driving of the water level detection sensor 620 is started at the same time.

The control from the time when the cleaning operation is performed to the time when the energization of the heat exchanger 700 is started is different from the case of the above-mentioned initial use, and the control and operation operation after the time P5 when the driving of the nozzle device 800 is started is different. The same is true.

As described above, in the configuration of the cleaning means, the sanitary cleaning device according to the present embodiment detects the change in the water level by the water level detection sensor provided in the sub tank without separately providing a dedicated flow rate sensor for detecting the flow rate. By adopting a configuration in which the flow rate is detected by calculation, the configuration of the cleaning means can be simplified and the cost can be reduced.

Further, by correcting the threshold value for determining the output voltage change between the electrodes in water level detection by temperature, the accuracy of water level detection and flow rate detection can be improved, and water having different conductivity in a wide range can be sanitized and cleaned. By making it possible to use it as cleaning water, it is possible to improve the range of use and usability of the sanitary cleaning device.

In addition, during the initial use of the sanitary cleaning device, water flow is continued for a predetermined time after detecting the full state of the sub tank, and the heat exchanger is energized after the water level detection sensor cancels the detection of the upper limit water level after the water pump is driven. By doing so, it is possible to prevent empty heating of the heat exchanger, and it is cheaper with a simpler configuration than the commonly used means of preventing empty heating using a flow sensor, and is safe and reliable. Can be secured.

<7> Control and operation of discharge of the spray nozzle to the inner surface of the toilet bowl FIG. 31 shows a perspective view showing the appearance of the spray nozzle, FIG. 32 shows a cross-sectional view of the spray nozzle, and FIG. 33 shows a sanitary cleaning device. FIG. 34 is a vertical sectional view showing the installation state of the spray nozzle in the sanitary cleaning device, FIG. 34 is a front view showing the installation state of the spray nozzle in the sanitary cleaning device, and FIG. It is a top view which shows. FIG. 36 is a chart showing the pump output at the rotation angle of the discharge port of the spray nozzle.

As shown in FIG. 32, the spray nozzle 550 has a rotary nozzle 550d rotatably shafted by an O-ring 550e and an O-ring 550f in a body 550c provided with an inlet flow path 550b by a spray nozzle drive unit 550a which is a motor. It is a sealed configuration. By using the X ring instead of the O-ring 550f, the torque required for rotational drive can be reduced, sticking can be easily prevented, and the spray nozzle drive unit 550a, which is a motor, can be made compact and low torque. can. The shaft 550n of the spray nozzle drive unit 550a is a rotary nozzle 5.
It is fitted to 50d.

The cleaning water or cleaning foam supplied from the inlet flow path 550b of the body 550c is discharged from the discharge port 550u through a plurality of inlet holes 550h formed around the rotary nozzle 550d.

As shown in FIGS. 34 and 35, the spray nozzle 550 is installed on the right side of the center of the main body 200. This is because priority is given to arranging the butt cleaning nozzle 831 or the like, which is a cleaning nozzle for cleaning the local part of the human body, in the center, so that the spray nozzle 550 is arranged on either the left or right side of the spray nozzle 550, not in the center. Is.

When the user enters the toilet, the control unit 130 of the sanitary cleaning device 100 detects the entry of a person by the human body detection sensor 450, and rotates the direction of the discharge port 550u of the spray nozzle 550 to drive the cleaning foam into the toilet bowl. The mode is set to the rotary foam spraying command (foam coat) mode, and the operation shifts to the rotary foam spraying operation on the toilet bowl, the operation of the water pump 516, which is a means for varying the amount of water discharged, is started, and the on-off valve 530a is opened.

At this time, since the flow control valve 517 that switches the flow path to the ass cleaning nozzle 831, the bidet cleaning nozzle 832, the nozzle cleaning unit 833, etc. is in the closed state, the cleaning water from the heat exchanger 700 is in the branch flow path 530 and the reverse. It is discharged from the spray nozzle 550 to the inner surface of the toilet bowl via the check valve 531 and the foam tank 532.

At that time, the control unit 130 drives the spray nozzle drive unit 550a of the spray nozzle 550, the direction of the discharge port 550u of the spray nozzle 550 is rotationally driven, and the cleaning water or cleaning foam discharged from the discharge port 550u drives the toilet bowl. A water film or a foam film is formed on the entire inner surface of the surface.

As shown in FIG. 35, the distance from the spray nozzle 550 to the inner surface of the toilet bowl differs depending on the rotation angle direction of the discharge port 550u of the spray nozzle 550. As shown in FIG. 36, the control unit 130 controls so as to change the output of the water pump 516, which is the water discharge amount variable means, according to the rotation angle of the discharge port 550u of the spray nozzle 550.

In the sanitary cleaning device of the present embodiment, the distance to the inner surface of the toilet bowl is the longest when the direction of the discharge port 550u of the spray nozzle 550 is 160 °, and the distance to the inner surface of the toilet bowl is the longest when the direction of the discharge port 550u is 340 °. The distance is the shortest. When the user's entry into the toilet is detected by the human body detection sensor 450, the control unit 130 outputs the output of the pump (water pump 516, which is a means for varying the amount of water discharged) according to the rotation angle of the discharge port 550u of the spray nozzle 550. Change like 36.

That is, when the rotation angle at which the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl is the longest (longest) is around 160 °, the output of the pump becomes large and the distance from the discharge port 550u to the inner surface of the toilet bowl is the longest. When the near (shortened) rotation angle is around 340 °, the ejection amount (and ejection speed) from the discharge port 550u is controlled so that the output of the pump becomes small.

Therefore, when the cleaning water is discharged to the front of the toilet bowl, which is the farthest distance from the discharge port 550u of the spray nozzle 550, the washing water is discharged with the strongest force, and the washing water reaches the inner surface in front of the toilet bowl, and the discharge port 550u of the spray nozzle 550 u. When the water is discharged to the rear of the toilet, which is the closest distance from the toilet, the cleaning water is discharged with the weakest force, so the cleaning water or cleaning foam spreads to the entire inner surface of the toilet without any problems such as scattering to the rear of the toilet. It can be discharged so as to be perfect, and a water film or a foam film can be formed up to the inner surface in front of the toilet bowl to suppress dirt adhesion.

When the human body detection sensor 450 detects that the user has entered the toilet, or by operating the spray switch 417 of the operation unit 210 or the remote controller 400, so-called toilet foam spraying is performed to spray the cleaning foam on the toilet bowl. Can be done. When the toilet bubble is sprayed by the signal of the toilet bubble spraying, the control unit 130 rotates the spray nozzle driving unit 550a in the normal direction while changing the output of the water discharge amount variable means 516 as shown in FIG. 36 described above. The direction of the discharge port 550u of the spray nozzle reaches the rear of the toilet bowl from the rear of the toilet bowl through the front of the toilet bowl, and the spray nozzle drive unit 550a is reversed so that the direction of the discharge port 550u of the spray nozzle is from the rear of the toilet bowl to the rear of the toilet bowl. It has a step of spraying bubbles by at least one reciprocating rotation operation.

As a result, the output of the water discharge amount variable means is controlled so that the cleaning foam reaches the vicinity of the rim of the toilet bowl, the cleaning foam can be sprayed almost all around the inner surface of the toilet bowl, and a foam film is formed from the front surface to the rear inner surface of the toilet bowl. It is possible to suppress the adhesion of dirt.

In this case, as shown in FIG. 36, the control unit 130 controls the output of the water discharge amount variable means at the time of normal rotation of the spray nozzle drive unit 550a to be lower than that at the time of reverse rotation of the spray nozzle drive unit 550a for cleaning. It may be configured to discharge bubbles. By the way, if the output of the water discharge amount variable means is increased, the momentum for discharging the cleaning foam is strengthened and the cleaning foam is sprayed to a place far from the spray nozzle, and if the output of the water discharge amount variable means is lowered, the momentum for discharging the cleaning foam is weakened. It is sprayed near the spray nozzle. As a result, when the direction of the discharge port 550u of the spray nozzle is driven by one reciprocating rotation as shown by the spray movement locus shown by the dotted line in FIG. 35, the cleaning foam is generated on the side closer to the draft surface inside the rim of the toilet bowl. It is sprayed. Then, the cleaning foam is sprayed on the side close to the rim of the toilet bowl at the time of reversal in which the direction of the discharge port 550u of the spray nozzle is driven by one reciprocating rotation as shown by the spraying movement locus shown by the broken line in FIG. 35.

As a result, the water surface above the outlet of the toilet bowl can be covered with cleaning foam early in the initial stage of spraying, and the cleaning foam can be sprayed almost all around the inner surface of the toilet bowl near the rim. A film can be formed to suppress dirt adhesion.

The installation position of the spray nozzle 550 is located in front of the main body 200 which is mounted and fixedly installed on the toilet bowl 110 as shown in FIGS. 2, 33, 34, 35 and the like. Since the spray nozzle 550 is installed on the front side of the front tip position in the state where the nozzle device 800 for cleaning the human body by projecting the cleaning nozzle 831 from the storage position to the butt cleaning or bidet cleaning position, the spray nozzle 550 is sprayed. The direction of the nozzle discharge port 550u can be rotationally driven to disperse bubbles to the rear of the toilet bowl, and a foam film can be formed from the front to the inner surface of the rear of the toilet bowl to suppress dirt adhesion.

In the above description, forward rotation is shown as clockwise rotation and reverse rotation is shown as counterclockwise rotation in FIG. 35, but forward rotation is clockwise and reverse rotation is counterclockwise, and forward rotation is counterclockwise rotation. It may be clockwise. In short, the direction in which the discharge port 550u of the spray nozzle starts to rotate at the time of spraying is called forward rotation, and the direction in which it returns is called reverse rotation.

In the above description, the output of the water pump 516, which is a means for varying the amount of water discharged, is controlled to be changed when the rotary foam is sprayed into the toilet bowl. Even if the output of the water pump 516, which is a means for varying the amount of water, is not changed, the spray nozzle 550 is configured as described below to form a foam film from the front to the rear inner surface of the toilet bowl to suppress dirt adhesion. Can be done.

As shown in FIGS. 33 and 34, the spray nozzle 550 is installed in the main body 200 with the rotation axis Ax of the discharge port of the spray nozzle that is rotationally driven tilted in the front-rear direction and the left-right direction, and is installed in the front-rear direction. The lower side of the rotating shaft Ax is inclined toward the front side of the toilet bowl 110, and the lower side of the rotating shaft Ax is inclined toward the cleaning nozzle 831. When the discharge port 550u faces the front of the toilet bowl 110, the direction of the discharge port 550u becomes high, and the cleaning foam can be sprayed near the rim in front of the toilet bowl 110, and sprayed from the discharge port 550u of the spray nozzle 550. When the discharge port 550u faces the rear of the toilet bowl 110 where the distance to the position is short, the direction of the discharge port 550u becomes low. Further, when the discharge port 550u faces the right side of the toilet bowl 110 where the distance from the discharge port 550u of the spray nozzle 550 to the spray position is slightly long, the direction of the discharge port 550u becomes slightly higher and close to the rim on the right side of the toilet bowl 110. When the cleaning foam can be sprayed and the discharge port 550u faces the left side of the toilet bowl 110 where the distance from the discharge port 550u of the spray nozzle 550 to the spray position becomes slightly shorter, the direction of the discharge port 550u becomes slightly lower.

In this way, when the rotary foam is sprayed from the spray nozzle to the toilet bowl, the spray nozzle drive unit 550a rotationally drives the direction of the discharge port 550u of the spray nozzle around the rotation axis Ax. The distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl changes with the rotation of the spray nozzle, but the cleaning foam is sprayed while the height of the discharge port 550u of the spray nozzle 550 changes with the rotation. , A foam film can be formed from the front of the toilet bowl to the inner surface near the rear rim by the spraying trajectory as drawn by the dashed arrow in the counterclockwise direction in FIG. 35, and dirt adhesion can be suppressed from the front to the rear inner surface of the toilet bowl. Can be done. Since the output of the water pump 516, which is a means for varying the amount of water discharged, is a constant output that does not change when the rotary foam is sprayed, the same locus as the counterclockwise dashed arrow is reversed in FIG. 35 when the rotary foam is sprayed counterclockwise. It is sprayed to follow.

Incidentally, in the present embodiment, the rotation axis Ax of the discharge port of the spray nozzle has an inclination angle β in the front-rear direction shown in FIG. 33 of 20 degrees and an inclination angle γ in the left-right direction shown in FIG. 34 of 10 degrees. Further, the height position of the discharge port 550u of the spray nozzle 550 is set to be lower than the upper end surface of the toilet bowl 110 at any rotation position.

As described above, the control unit 130 changes the output of the pump according to the rotation angle of the discharge port 550u of the spray nozzle 550, so that the washing water or the washing water can be used even if the distances to the front, side, and rear of the toilet bowl are different. The cleaning foam can be discharged so as to reach a wide range on the inner surface of the toilet bowl, and a water film or a foam film can be formed on a wide range on the inner surface of the toilet bowl to suppress dirt adhesion.

The operation unit 210 or the remote controller 400 may be provided with a level changeover switch capable of increasing or decreasing the level (average level) of the pump output described above. As a result, even if the size of the toilet bowl is different, the washing water or washing foam can be discharged so as to reach the entire inner surface of the toilet bowl, and a water film or foam film is formed up to the inner surface in front of the toilet bowl to suppress dirt adhesion. Can be done.

In addition to the control unit 130 changing the output of the pump according to the rotation angle of the discharge port 550u of the spray nozzle 550, the control unit 130 drives the spray nozzle according to the rotation angle of the discharge port 550u of the spray nozzle 550. The speed of the portion 550a may be changed. By changing the output of the pump (water pump 516, which is a means for varying the amount of water discharged), the momentum of discharge can be changed so that it reaches the inner surface of a distant toilet bowl, and in addition to being able to suppress scattering on the inner surface of a nearby toilet bowl, it also discharges water. By changing the speed of the spray nozzle drive unit 550a according to the rotation angle of the outlet 550u, the spray density can be further made even.

That is, when the discharge port 550u of the spray nozzle 550 rotates at a constant rotation speed, the spray density becomes coarse in the place where the distance to the inner surface of the toilet bowl is long, and the spray density becomes dense in the place where the distance to the inner surface of the toilet bowl is long. .. By changing the output of the pump (water pump 516, which is a means for varying the amount of water discharged), there is an effect of equalizing the spray distribution, but by changing the speed of the spray nozzle drive unit 550a according to the rotation angle, it becomes more uniform. In other words, it can be discharged evenly from the inner surface of the toilet bowl.

For example, in the rotation angle shown in FIG. 35, the washing water or washing bubbles sprayed in front of the toilet bowl at a rotation angle of around 160 °, which is the farthest distance from the discharge port of the spray nozzle, are dispersed and sprayed density. When discharged forward, the spray nozzle has the slowest rotation speed, the spray density is increased, and the rotation angle that is the closest distance to the discharge port of the spray nozzle is around 340 °. When discharged backward, the spray nozzle 550 has the fastest rotation speed and the spray density is diluted, so that the distribution of the wash water or wash bubbles sprayed on the inner surface of the toilet bowl can be more evened and dirt adhesion is suppressed. Can be done.

That is, the control unit 130 changes the speed of the spray nozzle drive unit 550a according to the rotation angle of the discharge port 550u of the spray nozzle 550, so that the direction of the discharge port 550u of the spray nozzle 550 has a long distance to the inner surface of the toilet bowl. The speed of the spray nozzle drive unit 550a is small when the rotation angle is in front of the toilet bowl, and the distance to the inner surface of the toilet bowl is short. Even if the distance to the back is different, the washing water or washing foam can be discharged evenly to the inner surface of the toilet bowl, and a water film or foam film is formed more evenly to the inner surface in front of the toilet bowl to prevent dirt from adhering. It can be suppressed.

After the control unit 130 detects the entry of a person by the human body detection sensor 450, the spray nozzle 550 sprays the cleaning foam on the inner surface of the toilet bowl. It automatically stops by spraying bubbles while being driven to rotate. As a result, when the user enters the toilet room, a foam film can be formed on the inner surface of the toilet bowl before use, and the adhesion of dirt can be suppressed. It should be noted that the configuration may be such that the spray is sprayed from the rotating discharge port 550u to the inner surface of the toilet bowl as many times as the number of times the spray is spread and stopped. Can be selected and set by the operation unit 210 or the remote controller 400.

Further, as shown in FIG. 36, the spray nozzle 550 is configured to reciprocate the rotary nozzle 550d of the spray nozzle 550 when spraying the cleaning water or the cleaning foam on the inner surface of the toilet bowl. The spraying direction of the washing water or the washing foam is not always the same as in the configuration in which the rotary nozzle 550d is rotated all around in either the right direction or the left direction, and the reverse rotation is caused by the reciprocating rotation. By spraying from the direction and spraying from two directions by this forward and reverse rotation, the so-called spraying omission part can be reduced and the spraying can be made easier to spread, so that dirt adhesion is suppressed with a small number of spraying times (time). Can be done.

In the chart of FIG. 36, the rotation angle corresponding to the rear side of the toilet bowl is rotated forward from 0 ° to a rotation angle of 340 °, and then temporarily stopped. The behavior to do is shown. The rotary nozzle 550d of the spray nozzle 550 is provided with a rotation control portion (not shown) whose rotatable range is regulated by a mechanical stopper from a rotation angle of 0 ° to a rotation angle of 340 °.

The rotation control unit (not shown) is a spray nozzle drive unit 550a when a protrusion formed on a part of the outer periphery of the rotation nozzle 550d rotates together with the rotation nozzle 550d and comes into contact with the rotation regulation wall of the body 550c. Even if the motor tries to rotate the rotary nozzle 550d, it is mechanically in contact with the rotary nozzle 550d, so that the motor slips and slips, and the rotary nozzle 550d cannot rotate.

In this way, by providing a rotation control unit (not shown) that regulates the rotation range and configuring the spray nozzle 550 to reciprocate within a rotation range that is not regulated by the rotation regulation unit, the spray nozzle 550 can be reciprocated from the opposite direction. By spraying and spraying from two directions by this forward and reverse rotation, so-called spraying omissions can be reduced and spraying can be performed more easily, so that dirt adhesion can be suppressed with a small number of spraying times (time). ..

Further, the spray nozzle drive unit 550a is composed of a motor so that the origin of the rotation position of the spray nozzle drive unit can be recognized at the position where the rotation regulation unit abuts, and the accuracy of the rotation angle position and the rotation speed is high. Can be sprayed with extremely little variation.

As described in the water circuit configuration with reference to FIG. 6, the branch flow path 530 branched between the water pump 516 and the flow control valve 517, which are means for varying the amount of water discharged, of the wash water supply flow path 690 opens and closes. The foam tank 532 is connected to the foam tank 532 via the valve 530a and the check valve 531 so that the washing water is supplied, and the spray nozzle 550 is connected to the downstream of the foam tank 532. A detergent tank 533 that supplies detergent to the foam tank 532 and a detergent pump 534 are connected to the foam tank 532, and an air pump 535 that sends air to the foam tank 532 to create cleaning foam is provided.

By the way, when the control unit 130 opens the on-off valve 530a, the washing water from the heat exchanger 700 is sent by the water pump 516 which is a means for varying the amount of water discharged, so that the washing water or the washing foam is discharged from the spray nozzle 550. NS. At that time, the discharge amount and the discharge momentum (discharge speed and discharge rate) of the washing water or washing foam discharged from the spray nozzle 550 according to the increase / decrease in the output of the water pump (pump) 516 and the air pump 535, which are means for changing the amount of water discharge. Discharge pressure) is increased or decreased.

The branch flow path 530 may be provided with the on-off valve 530a, or the branch flow path 530 and the wash water supply flow path 690 may be provided with a flow path switching valve at the branch portion.

The user can select whether to spray the cleaning water or the cleaning foam from the spray nozzle 550 by the operation unit 210 of the main body 200 or the remote controller 400. A foam tank 532 in which detergent is supplied between the on-off valve 530a and the spray nozzle 550 to generate cleaning foam is provided, and the cleaning foam is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl. By forming a foam film by washing foam containing a detergent instead of simply forming a water film by spraying water or warm water, the effect of suppressing dirt adhesion can be further enhanced. In addition, the foam film formed by the cleaning foam containing detergent can suppress unpleasant odors and improve the comfort of a visually clean image.

In the sanitary cleaning device of the present embodiment, the cleaning water or cleaning foam is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl by the operation unit 210 or the remote, separately from the case where the human body detection sensor 450 detects the entry of a person. By operating the spraying switch 417 of the controller 400, spraying can be performed, and whenever dirt is a concern, a foam film containing cleaning foam containing detergent can be formed to clean the surface.

The user can arbitrarily select whether to spray the washing water or the washing foam from the spray nozzle 550 on the inner surface of the toilet bowl by using the spray selection switch (not shown) of the operation unit 210 or the remote controller 400 in advance. be able to.

Further, the control unit 130 has a sugi issuing mode that can be selected and instructed by the switch button of the operation unit 210 or the remote controller 400, and supplies the detergent of the detergent tank 533 of the foam generating unit 560 to the foam tank 532 in the sugi issuing mode. The on-off valve 530a may be opened with the detergent pump 534 stopped, and the cleaning water may be sent to the foam tank 532 by the water discharge amount variable means 516 and discharged from the spray nozzle 550.

As a result, the path from the foam tank 532 to the spray nozzle 550 is rinsed with washing water, and it is possible to prevent clogging due to the sticking of the detergent on the path and the spray nozzle 550 and rotation failure due to the sticking of the detergent on the spray nozzle 550. .. In addition, the inner surface of the toilet bowl can be rinsed.

That is, since the detergent pump 534 is stopped during this rinsing operation, the washing water is sent to the foam tank 532 without supplying the detergent, so that the path from the foam tank 532 to the spray nozzle 550 is rinsed with the washing water. The inner surface of the toilet bowl can be rinsed with washing water.

Further, during this rinsing operation, rinsing can be performed with washing water whose temperature is not controlled, but a better rinsing effect can be obtained by controlling the temperature of the washing water sent from the heat exchanger 700 to about 40 ° C. ..

By operating the Susugi switch 223 of the operation unit 210 in which the user sets the Susugi issuing mode, rinsing can be performed at any time.

In addition, when a sugi lamp 223a such as an LED is provided in the vicinity of the sugi switch 223 of the operation unit 210 for setting the sugi issuing mode, the control unit 130 waits for a predetermined time such as 20 days after the previous rinsing. The configuration in which the sugi lamp 223a blinks automatically prevents forgetting to rinse.

When the cleaning foam is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl, the control unit 130 uses an air pump as in the case shown in the pump output of FIG. 36 described above according to the rotation angle of the discharge port 550u of the spray nozzle 550. The output of 535 may be changed. As a result, even if the distances to the front, side, and rear of the toilet bowl are different, the cleaning foam can be discharged so that it reaches the entire inner surface of the toilet bowl, and a foam film is formed up to the inner surface in front of the toilet bowl to prevent dirt from adhering. It can be suppressed.

That is, when the rotation angle at which the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl is the longest (longest) is around 160 °, the output of the air pump 535 becomes large, so that the air pressure by the air pump 535 becomes high. The output of the air pump 535 becomes small when the rotation angle at which the distance from the discharge port 550u to the inner surface of the toilet bowl is the shortest (shortest) is around 340 °. As a result, the air pressure by the air pump 535 is lowered, and the force of blowing the cleaning foam is weakened, so that the cleaning foam can be uniformly discharged to the inner surface of the toilet bowl.

Further, a dirt detecting means (not shown) for detecting dirt on the toilet bowl with an image element or the like is further provided, and the control unit 130 partially reciprocates the remaining dirt and sprays it intensively to make it more dirty. The suppressing effect can be improved. In addition to the method of partially reciprocating the dirty portion, the rotation speed when the discharge port 550u of the spray nozzle 550 passes through the dirty portion may be set to a low rotation speed, or the pump output may be increased.

<8> Control and action operation of discharge by the spray nozzle in the open / non-seated state of the toilet seat Next, the toilet seat 300 is opened almost vertically while the user is not seated on the toilet seat 300 as in the case of male urine. A case where the spray switch of the operation unit 210 or the remote controller 400 is operated in this state will be described.

In this case, since the user is in the standing posture and the toilet seat 300 is open, the signal of the toilet seat open / close detection unit 331 is in the toilet seat open state, and the signal of the seat detection unit 330 is in the non-seating state. When the spray switch 417 is pressed by the user, as shown in FIG. 37, the control unit 130 is at a position where the direction of the discharge port 550u of the spray nozzle 550 faces the discharge port 115 of the toilet bowl (in the present embodiment, FIG. As shown in the chart of FIG. 37, the spray nozzle drive unit 550a is rotationally driven to stop until the discharge port 550u has a rotation angle of about 150 °), and then the water discharge amount variable means 516 is controlled with a medium output to be controlled in FIG. 37. As shown by the arrow, the cleaning foam is discharged to the discharge port 115 of the toilet bowl for a predetermined time (8 seconds in the present embodiment). The discharged cleaning foam is in a state of covering the upper part of the water surface of the discharge port 115 of the toilet bowl 110, that is, the upper part of the draft surface in the toilet bowl with foam.

With respect to the rotary foam spraying in which the cleaning foam is sprayed into the toilet bowl while rotationally driving the direction of the discharge port 550u of the spray nozzle 550 by the rotary foam spraying command (foam coating) mode of the control unit 130 described in the above <7> section. The item <8> is a fixed foam spraying method in which the cleaning foam is sprayed into the toilet bowl while the direction of the discharge port of the spray nozzle is fixed by the fixed foam spraying command (splash suppression) mode of the control unit 130.

As described above, when the user is not seated on the toilet seat 300 as in the case of male urine and the toilet seat 300 is opened almost vertically, the manual operation unit 210 or the remote controller 400 is a spray switch. When the splash suppression switch 434 is operated, as shown in FIG. 37, the control unit 130 is at a position where the direction of the discharge port 550u of the spray nozzle 550 faces the rear of the toilet bowl (in the present embodiment, the chart in FIG. 37 shows. As shown, the spray nozzle drive unit 550a is rotationally driven to stop at the rotation angle of the discharge port 550u (around 20 °), and then the water discharge amount variable means 516 is controlled with a high output to clean the foam as shown by the arrow in FIG. 37. Is discharged to the rear of the toilet bowl for a predetermined time (8 seconds in this embodiment).

In this case, as shown in the cross-sectional view of FIG. 33, the discharge port 550u of the spray nozzle 550 is open at an angle α degree with respect to the rotation axis of the spray nozzle 550: Ax. Direction: The cleaning foam is discharged in a state of being stopped and fixed in the direction of Ac (b).

In this way, after the direction of the discharge port 550u of the spray nozzle 550 is rotationally driven to the rear of the toilet bowl, the water discharge amount variable means 516 is controlled with a high output, and the cleaning foam is generated on the water surface above the discharge port 115 in the toilet bowl and in the toilet bowl. The upper part of the waterline can be quickly covered with foam, and the cleaning foam can suppress odor and dirt adhesion near the water surface of the toilet bowl. In addition, when urine falls near the water surface in the toilet bowl, the cushioning effect of the bubbles covering the water surface can prevent the urine from bouncing back to the surroundings. That is, it is possible to quickly spray a large amount of foam in the direction in which the spray nozzle 550 is fixed to form bubbles on the upper part of the water surface in the toilet bowl and prevent urine from splashing and scattering.

In the present embodiment, when the user operates the manual splash suppression switch 434 of the remote controller 400 during male urination, the control unit 130 enters the fixed foam spraying command (splash suppression) mode, and the discharge port 550u of the spray nozzle 550 u. After rotating and stopping the spray nozzle drive unit 550a to a position where the direction of Although it is configured, the position where the cleaning foam is fixedly sprayed may be any of the front side, the center, and the rear side of the toilet bowl near the discharge port 115.

In other words, by quickly covering the draft surface and the upper part of the toilet bowl waterline with foam within a short time of a few seconds after the cleaning foam starts to be discharged, it is possible to suppress the splashing and scattering of urine.
It is possible to suppress the adhesion of dirt near and above the waterline in the toilet bowl.

In the fixed foam spraying mode in which the cleaning foam is sprayed into the toilet bowl while the direction of the discharge port of the spray nozzle is fixed by this fixed foam spraying command (splash suppression) mode, the water discharge amount variable means 516 is controlled with a high output in FIG. 37. The cleaning foam was discharged toward the discharge port 115 of the toilet bowl, but the output of the water pump 516, which is a means for varying the amount of water discharged, is constant, as in the case of the rotary foam spraying described in <7> above. The output, that is, the output of the water pump 516, which is a means for varying the amount of water discharged during fixed foam spraying, may remain the same as that during rotary foam spraying.

As described above, the sanitary cleaning device of the present embodiment includes a main body 200 installed in the toilet bowl 110, a cleaning nozzle 831 for cleaning the human body, a foam generating unit 560 for generating cleaning foam, and cleaning water or cleaning water on the inner surface of the toilet bowl.

The control unit 130 includes an on-off valve 530a for opening and closing the water passage to the water channel, a control unit 130 for controlling these operations, and an operation unit 210 for instructing and setting the operation of the control unit. Rotational foam spraying issuance (foam coat) mode that sprays cleaning foam into the toilet while rotating, and fixed foam spraying (splash suppression) that sprays cleaning foam into the toilet while keeping the direction of the discharge port 550u of the spray nozzle fixed. ) With the configuration having a mode, when the cleaning foam is sprayed from the spray nozzle 550 to the toilet bowl, the cleaning foam is sprayed widely in the toilet bowl while the direction of the discharge port 550u of the spray nozzle is rotationally driven. A foam film can be formed from the front to the rear inner surface to suppress the adhesion of dirt on the inner surface of the toilet bowl and the vicinity of the water line.

Further, by the fixed foam spraying command mode in which the cleaning foam is sprayed into the toilet bowl while the direction of the discharge port 550u of the spray nozzle is fixed, the cleaning foam is quickly formed on the upper part of the water surface in the toilet bowl, and the water surface on the upper part of the discharge port in the toilet bowl. Can be covered with the cleaning foam, so that the unpleasant odor during urination and the scattering due to splashes during male urine can be suppressed by the cleaning foam.

As a result of a verification experiment on the effect of suppressing scattering due to splashing during male urine, as shown in FIG. 49, there is an effect that the thickness of bubbles, which is the height of bubbles, is improved from about 5 mm as compared with no bubbles. It was confirmed that the suppressing effect became remarkable when the thickness of the foam was about 10 mm. That is, it is preferable that the lower limit of the thickness of the foam on the water surface in the toilet bowl by spraying the foam is 5 mm or more and the upper limit is 50 mm or less. In addition, 50 mm or less is an upper limit by setting the foam height so that the accumulated foam does not adhere to the buttocks when the user sits on the toilet seat.

Further, in the sanitary cleaning device of the present embodiment, the spray nozzle 550 is installed on the main body 200 with the rotation axis Ax of the discharge port 550u of the spray nozzle that is rotationally driven tilted in the front-rear direction and the left-right direction. The lower side of the rotating shaft Ax is inclined toward the front side of the toilet bowl 110, and the inclination in the left-right direction is such that the lower side of the rotating shaft Ax is inclined toward the cleaning nozzle 831. When spraying bubbles, the distance from the discharge port 550u of the spray nozzle to the spray position becomes long. When the discharge port 550u faces the front of the toilet bowl, the direction of the discharge port 550u becomes high, and the direction from the discharge port 550u of the spray nozzle to the spray position When the discharge port 550u faces the rear of the toilet bowl, the direction of the discharge port 550u becomes low. In this way, the cleaning foam can be sprayed while the height of the discharge port 550u of the spray nozzle changes according to the distance from the discharge port 550u of the spray nozzle to the inner surface of the toilet bowl. It is possible to suppress the adhesion of dirt by forming a foam film from the front surface of the toilet bowl to the inner surface behind the toilet bowl without changing the output of the toilet bowl.

Further, in the sanitary cleaning device of the present embodiment, when the rotary foam is sprayed from the spray nozzle 550 to the toilet bowl 110, the control unit 130 rotates the spray nozzle drive unit 550a in the normal direction so that the direction of the discharge port 550u of the spray nozzle is the toilet bowl. From the rear to the rear of the toilet, the spray nozzle drive unit 550a is reversed, and the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet through the front of the toilet to the rear of the toilet. Due to the configuration having the process, when the rotary foam is sprayed from the spray nozzle 550 to the toilet bowl, the control unit 130 rotates the spray nozzle drive unit 550a in the normal direction so that the direction of the discharge port 550u of the spray nozzle is from the rear of the toilet bowl. After reaching the rear of the toilet through the front of the toilet, the spray nozzle drive unit 550a is reversed so that the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet through the front of the toilet to the rear of the toilet. The output of the water discharge amount variable means is controlled so that the water reaches the vicinity of the rim of the toilet bowl, and the cleaning foam can be sprayed almost all around the inner surface of the toilet bowl, forming a foam film from the front to the rear inner surface of the toilet bowl to suppress dirt adhesion. be able to.

When detected, the rotation foam is sprayed on the toilet bowl by at least one reciprocating rotation operation, so that when the human body detection sensor 450 detects the user entering the toilet room, the direction of the discharge port 550u of the spray nozzle rotates at least one reciprocating. While being driven, rotary foam spraying is possible in which cleaning foam is sprayed on the inner surface of the toilet bowl, and a foam film is surely formed on the inner surface of the toilet bowl before use to suppress the adhesion of dirt.

Further, in the sanitary cleaning device of the present embodiment, the cleaning water is sent to the foam tank 532 by the water discharge amount variable means 516 when the control unit 130 opens the on-off valve 530a, and the detergent of the detergent tank 533 is transferred to the foam tank 532. The surface of the cleaning nozzle 831 or the inner surface of the toilet bowl is provided with a detergent pump 534 to supply the detergent and an air pump 535 to supply the air to the foam tank, and the cleaning water or the cleaning foam of the foam tank 532 is discharged from the spray nozzle 550. Not only water or hot water is discharged, but cleaning foam containing a detergent is discharged, so that the cleaning effect and the effect of suppressing dirt adhesion can be enhanced. In addition, the cleaning foam containing a detergent can suppress an unpleasant odor and improve a visually clean and comfortable feeling.

Further, in the sanitary cleaning device of the present embodiment, the control unit 130 has a sugi issuing mode, and in the sugi issuing mode, the detergent pump 534 that supplies the detergent of the detergent tank 533 of the foam generating unit 560 to the foam tank 532 is stopped. In this state, the on-off valve 530a is opened, and the cleaning water is sent to the foam tank 532 by the water discharge amount variable means 516 and discharged from the spray nozzle 550, so that the path from the foam tank 532 to the spray nozzle 550 is rinsed with the cleaning water. , It is possible to prevent clogging due to the sticking of the detergent on the path and the spray nozzle 550, and rotation trouble due to the sticking of the detergent on the spray nozzle. In addition, the inner surface of the toilet bowl can be rinsed.

In the present embodiment, the motor is used as the spray nozzle drive unit 550a, but the spray nozzle 550 is rotated by the action of discharging cleaning foam from another drive source, for example, the discharge port 550u of the spray nozzle 550. It may be configured to cause.

Further, a spray nozzle 550 for spraying the cleaning foam near the rim of the toilet bowl and a spray nozzle 550 for spraying the cleaning foam near the discharge port 115 of the toilet bowl may be provided. These plurality of spray nozzles 550 may be rotated independently, or may be rotated in conjunction with each other.

Further, the spray nozzle 550 may be provided with a discharge port 550u for spraying cleaning foam near the rim of the toilet bowl and a discharge port 550u for spraying cleaning foam near the discharge port 115 of the toilet bowl.

In the present embodiment, the spray nozzle 550 is configured to spray at two locations, near the rim of the toilet bowl and near the discharge port 115 of the toilet bowl, but in addition to the vicinity of the rim of the toilet bowl and the vicinity of the discharge port 115 of the toilet bowl, It may be sprayed to other positions.

Further, as shown in FIGS. 34, 38, and 39, in the sanitary cleaning apparatus of the present embodiment, a sleeve case 250 is integrally provided so as to project forward from the side portion of the main body 200, and the sleeve portion thereof is provided. A sleeve lid 217 provided in front of the operation unit 210 arranged on the upper part of the case 250, and inside the sleeve lid 217, at the front of the sleeve case 250, a transparent or translucent container of the foam generating portion 560. The detergent tank 533 is built-in, and the detergent liquid level confirmation window 216 that can visually confirm the detergent liquid level position of the detergent tank 533 is provided on the front surface of the sleeve case 250, so that the user can use the sanitary cleaning device. Since the remaining amount of detergent can be easily visually confirmed when the previous operation is performed, the detergent can be replenished before the detergent runs out.

As described above, the detergent tank 533 having the detergent injection port 537 provided with the detergent tank lid 536 above is installed in the foremost part in front of the operation part 210 of the sleeve case 250, and is located closest to the front of the toilet bowl. Therefore, it is possible to easily replenish the detergent. Further, since the detergent tank 533 having the detergent injection port 537 is installed at the frontmost portion in front of the operation portion 210 of the sleeve case 250, the sleeve lid 217 in front of the operation portion 210 is opened to inject detergent. When the detergent is replenished from the inlet 537 to the detergent tank 533, the detergent can be prevented from spilling onto the operation unit 210. Further, as shown in FIGS. 38 and 39, the height position of the detergent injection port 537 is lower than that of the operation unit 210, so that the detergent is operated more when the detergent tank 533 is replenished with the detergent. It is possible to prevent the portion 210 from spilling.

Further, in the sanitary cleaning device of the present embodiment, the detergent pump hose 561 shown in FIGS. 6 and 38 is a cylindrical tube having a hollow inside for guiding the detergent from the outlet side of the detergent pump 534 to the inlet side of the foam tank 532. It is formed of a so-called double hose, which is further coated on the outside of the tube. Further, the inner diameter of the detergent pump hose 561 is smaller than the inner diameter of the foam tank hose 562 that guides the cleaning foam from the foam tank 532 to the spray nozzle 550. With the above configuration, it is possible to prevent the detergent pump hose 561 from swelling or bursting even when a high pressure from the detergent pump 534 acts, and it is possible to stably spray the cleaning foam from the spray nozzle 550. ..

Incidentally, in the sanitary cleaning device of the present embodiment, the detergent pump hose 561 having a double hose structure is composed of a double hose in which the outside of the elastomer resin tube is covered with a heat shrinkable tube, but the material is limited to this. Even if there is no other material, the double hose can prevent swelling and rupture, and the cleaning foam can be stably sprayed from the spray nozzle 550.

Further, as can be seen from FIGS. 2, 39 and 40, in the sanitary cleaning device of the present embodiment, the main body 200 having the control unit 130, the spray nozzle 550, the nozzle device and the like inside is the rear main body case 201. The front surface is covered with the main body case 202.
The spray nozzle 550 is installed in the front portion of the rear main body case 201, the front surface and the upper portion of the spray nozzle 550 are covered with the main body case 202, and the discharge port 516e at the lower portion of the spray nozzle 550 is opened to the inner surface of the toilet bowl. It is installed in.

Note that FIG. 40 is a cross-sectional view showing the central portion of the spray nozzle 550 installed in the rear main body case 201 cut in the front-rear direction. The cleaning foam discharged from the discharge port 516e of the spray nozzle 550 is normally discharged to the inner surface of the toilet bowl as shown by the dotted line T in FIG. 40. However, when the cleaning water containing no detergent and having no bubbles is discharged from the spray nozzle 550 from the discharge port 516e by the above-mentioned Susugi issuing mode, as in the case of rinsing, the two-dot chain line S in FIG. 40 is used. As shown, the jets can diffuse and splatter, causing problems such as splattering out of the toilet bowl and wetting the floor.

As shown in FIG. 40, in the sanitary cleaning device of the present embodiment, the main body case 202 is formed with a scattering guard portion 550z in which an upward jet exceeding the upper limit of the spray nozzle 550 from the discharge port 516e is blocked by a wall and dropped into the toilet bowl. Has been done. The scattering guard portion 550z that blocks the upward jet flow exceeding the upper limit from the discharge port 516e can prevent the cleaning foam and the cleaning water discharged from the spray nozzle 550 from being ejected to the outside of the toilet bowl and can be sprayed into the toilet bowl.
That is, a part of the main body case 202 of the main body 200 that covers the front and the upper part of the spray nozzle 550 has a scattering guard portion 550z that blocks the upward jet flow exceeding the upper limit from the discharge port 550u of the spray nozzle 550 and drops it into the toilet bowl. Therefore, it is possible to prevent the cleaning foam and the cleaning water discharged from the spray nozzle 550 from being ejected to the outside of the toilet bowl.

Further, the scattering guard portion 550z formed on the main body case 202 not only prevents the cleaning foam and the cleaning water discharged from the spray nozzle 550 from being ejected to the outside of the toilet bowl. The sanitary cleaning device has a configuration in which the main body 200 can be attached to and detached from the toilet bowl 110 via the main body fixing plate 240. The main body of the sanitary cleaning device that was removed when the contractor or user initially installed the toilet bowl, or when the user wants to remove the main body 200 from the toilet bowl 110 and clean the dirt near the lower part of the back of the main body 200. The 200 may be temporarily placed on a table or on the floor.

In this way, when the main body 200 of the sanitary cleaning device is randomly placed on the table or on the floor, the discharge port 516e of the spray nozzle 550 located below the mounting surface of the main body 200 scatters and guards the guard portion 550z. This can protect the table and floor from contact with the spray nozzle 550 and prevent damage to the spray nozzle 550. The two-dot chain line of FIG. 41 showing the front view of the main body 200 and FIG. 42 showing the side view of the main body 200 shows the surface of the table when the main body 200 is placed. As shown in FIGS. 41 and 42, the ejection port 516e of the spray nozzle 550 does not come into contact with the surface of the table due to the scattering guard portion 550z.

In the sanitary cleaning device of the present embodiment, the scattering guard portion 550z is formed in the main body case 202, but the scattering guard portion 550z may be formed in the body 550c of the spray nozzle 550 or the like.

FIG. 43 shows a perspective view of the main body fixing plate 240 and the rear main body case 201 of the main body 200. The perspective view of the rear main body case 201 is a view in which the control unit 130, the spray nozzle 550, the nozzle device, and the like installed inside are omitted for convenience of explanation.
The main body fixing plate 240 is fixed to the toilet bowl through a mounting bolt (not shown) through the elongated hole 241 for adjusting the position. Then, align the center of the main body fixing plate 240 and the main body 200, lift the rear part of the main body fixing plate 240 a little, slide the main body 200 from the toilet surface and push it in until it makes a clicking sound. It is a configuration that is fixed to.

Further, when removing the main body 200 from the toilet bowl 110, the main body 200 can be removed by pulling it forward while pushing the main body attachment / detachment button 242 on the side of the main body 200 as far as it will go.

Further, as shown in FIG. 43, a magnet 243 is embedded in the resin main body fixing plate 240, and the main body 200 is attached to the toilet bowl 110 in the rear main body case 201. A detachable sensor 244 that can detect whether it is removed from the toilet is attached.

The detachable sensor 244 is composed of a reed switch, and as shown in the partial cross-sectional view shown in FIG. 44, the detection of the state in which the main body 200 is attached to the toilet bowl 110 is detected by the magnet 243 of the main body fixing plate 240 and the rear main body case 201. It can be detected by the positional relationship of the detachable sensors 244 facing each other. Further, when the main body 200 is removed from the toilet bowl 110, the detachable sensor 244 can detect the detached state by separating the magnet 243 and the detachable sensor 244.

When the control unit 130 detects that the main body 200 has been removed from the toilet bowl 110 by the detachable sensor 244, the discharge operation from the spray nozzle 550 is not executed. As a result, when the main body 200 is removed from the toilet bowl 110, buttons for instructing the discharge operation from the spray nozzle 550, such as the manual foam coat switch 433 and the manual splash suppression switch 434 of the remote control main body 401, are pressed. However, since the discharge operation from the spray nozzle 550 is not executed, it is possible to prevent a problem that the cleaning foam is inadvertently ejected to the floor or a person.

Further, even when the control unit 130 recognizes that the main body 200 is removed from the toilet bowl 110 by the detachable sensor 244, the discharge operation from the butt cleaning nozzle 831 and the bidet cleaning nozzle 832 is not prohibited. As a result, even in the unlikely event that the detachable sensor 244 fails and the main body 200 is erroneously recognized as being removed from the toilet bowl 110, it is a basic function of the sanitary cleaning device and is a user. Butt cleansing and bidet cleansing, which are important for, can be made feasible.

Further, FIG. 45 shows a time chart for spraying rotary foam with the sanitary cleaning device of the present embodiment. When the manual foam coat switch 433 of the remote control main body 401 is pressed, the detergent pump 534 reverses for 2 seconds at the time of N2 shown in FIG. 45, then starts normal rotation at the time of N3, and the water pump 516 and the air pump 535. Is operated to supply detergent, water, and air to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed on the inner surface of the toilet bowl from the discharge port 550u of the spray nozzle 550. By spraying the rotating foam on the inner surface of the toilet bowl, it is possible to prevent the inner surface of the toilet bowl from getting dirty and to easily remove the dirt.

At this time, the discharge port 550u of the spray nozzle 550 is rotationally driven by the spray nozzle drive unit 550a, which is a stepping motor. In the time chart of FIG. 45, the discharge port 550u of the spray nozzle 550 sprays bubbles while rotating forward from the stop position at the time of N3 to the end position at the time of N6, and then sprays bubbles from the end position at the time of N6 to N9. While reversing to the stop position at the time point, foam is sprayed and returned. Then, at the time of N11, the operation of the water pump 516 and the air pump 535 is automatically stopped, and the rotary foam spraying is automatically terminated.
Between N3 and N11 where the rotary foam is sprayed, the control unit 130 continuously operates the water pump 516 and the air pump 535, while the detergent pump 534 rotates forward from N3 to N4 and stops. The operation is intermittent, such as rotating forward from N6 to N7 and stopping, and rotating forward from N9 to N10 and stopping. Experiments have shown that intermittent operation of the detergent pump 534 during rotary foam spraying is more favorable for mixing detergent, water and air, and more stable cleaning foam can be produced. In this way, by intermittently operating the detergent pump 534 during the spraying of the rotary foam, stable cleaning foam can be generated. In addition, it is possible to prevent wasteful use of the detergent, and it is possible to reduce the trouble of replenishing the detergent.

Incidentally, in the sanitary cleaning device of the present embodiment, the detergent pump 534 is operated for 2 seconds in a 6-second cycle for intermittent operation.

Further, in the time chart for performing rotary foam spraying shown in FIG. 45, the chart of the heat exchanger 700 is drawn by a broken line, which is drawn from the water pump 516 to the foam tank 532 when performing rotary foam spraying. When the temperature of the supplied water is lower than 20 ° C., the heat exchanger 700 controls the heating so that the water temperature becomes about 20 ° C. so that the water is supplied to the foam tank 532. If the water temperature is low, the foaming property is lowered, but by supplying the heat exchanger 700 so that the water temperature is about 20 ° C., a preferable cleaning foam can be generated in the foam tank 532.

Further, in the time chart for performing the rotary foam spraying shown in FIG. 45, the detergent pump 534 is inverted from N2 to N3 immediately before the time point N3 when the rotary foam spraying is started, which is the detergent pump 534. A tube pump is used for the tube, and the detergent solution on the outlet side of the tube flows back to the part of the tube that was crushed by the roller due to the previous reversal, and the crushed part is restored to a cylindrical shape and then rotates forward. This makes it possible to deliver a stable amount of detergent.

Further, in the time chart for performing the rotary foam spraying shown in FIG. 45, the spray nozzle drive unit 550a is driven from the stop position to the origin position from N11 to the time point N14 when the rotary foam spraying ends. After pressing the rotation detection micro switch and recognizing the origin position of the spray nozzle drive unit 550a which is a stepping motor, the control unit 130 drives and controls the operation so as to return to the stop position.

In this way, due to the origin reset operation of the spray nozzle drive unit 550a, the stepping motor of the spray nozzle drive unit 550a causes a slip phenomenon due to some increase in rotational load or the like, and the rotation amount cannot be driven by the number of drive steps. Even if the deviation occurs, the stop position, which is the start position of the rotary foam spraying, can be correctly corrected and reset to start driving. That is, the rotary foam can always be sprayed at a stable position.

Further, the rotation detection microswitch pressed by the origin reset operation of the spray nozzle drive unit 550a causes the detergent to stick around the discharge port 550u of the spray nozzle 550 for some reason, and rotates until the rotation detection microswitch is pressed. It is possible to detect when driving becomes impossible. That is, when the rotation detection micro switch is not pressed when the rotation foam is sprayed, the sugi lamp 223a can be turned on to notify the rotation detection micro switch in order to encourage the sugi operation by the sugi switch 223.

In the sanitary cleaning device of the present embodiment, the time from the N3 time point when the rotary foam spraying is started to the N12 time point when the rotary foam spraying is finished is set to about 15 seconds. In this about 15 seconds, the amount of foam to be accumulated can be changed to about 10 seconds, about 25 seconds, etc. according to the size of the toilet bowl.

When the time until the rotation detection micro switch is pressed is delayed by about 10% or more with respect to the set rotation bubble spraying time, the Susugi lamp 223a is lit and displayed so as to repeat blinking once with "chika" and "chika". , Press the sugi switch 223 to urge the sugi operation. The sugi operation is washed for about 3 minutes while flowing washing water heated to about 40 ° C. in the heat exchanger 700. By this sugi operation, the foam generating part 560 and the spray nozzle 550 and the like are rinsed with washing water, and the detergent is prevented from sticking and clogging to the foam generating part 560 and the spray nozzle 550 and the like, and stable foam spraying is performed. Can be done.

When the time until the rotation detection micro switch is pressed is delayed by about 20% or more with respect to the set rotation foam spraying time due to the detergent etc. becoming stuck in the spray nozzle 550, the Susugi lamp 223a is "chika, chika". , "Chika, Chika" is lit and displayed so as to repeat blinking twice, and while pressing the sugi switch 223 to perform the sugi operation, it is urged to clean the vicinity of the discharge port 550u of the spray nozzle 550 with a toothbrush or the like.

Further, in the time chart for spraying the rotary foam shown in FIG. 45, the flow path switching chart shows the washing water from the water discharge amount variable means 516 which is the water pump in the water circuit of FIG. 6 at the time points N2 to N3. The supply destination is switched from the nozzle device 800 side to the bubble generating section 560 side, and at the time points N11 to N13, the operation of switching from the bubble generating section 560 side to the nozzle device 800 side is shown. That is, at the time points N2 to N3, the flow control valve 517 is closed and the on-off valve 530a is opened, and at the time points N11 to N13, the on-off valve 530a is closed and the flow control valve 517 is opened. In addition, instead of the on-off valve 530a, a flow path switching valve may be provided at a branching point where the branch flow path 530 is branched from the washing water supply flow path 690, and the flow path switching valve may be used to switch the flow path. good.

In addition, FIG. 46 shows a time chart of the sanitary cleaning device of the present embodiment during operation of the sugi.
It was shown to.
When the sugi switch 223 of the operation unit 210 is pressed and the control unit 130 enters the sugi issuing mode, the supply destination of the washing water is switched from the nozzle device 800 side to the bubble generation unit 560 side at the time points N2 to N3. Then, for about 2 minutes at the time points N3 to N8, the cleaning water heated to about 40 ° C. by the heat exchanger 700 is discharged into the foam tank by the water discharge amount variable means 516 while the detergent pump 534 is stopped. Water is sent to 532 and discharged from the spray nozzle 550. Further, for about 1 minute at N8 to N10, in addition to the washing water heated to about 40 ° C., the air pump 535 that sends air to the foam tank 532 is operated for rinsing and washing.

In this way, during the rinsing and washing operation, only the washing water is first sent, and the air pump 535 is operated from the middle of the operation to rinse while adding air, so that the water first remains in the foam tank 532 and the flow path. The coarse detergent component is quickly and efficiently discharged from the spray nozzle 550 by the washing water, and then the force of air bubbles from the air pump 535 is added to act so that even a small residual amount of the detergent component is rinsed. , Effective rinsing can be performed in a short time.

After about 3 minutes of rinsing and washing from N3 to N10, in N10 to N14, the detergent pump 534 is inverted and forward-rotated so that rotary foam spraying and fixed foam spraying can be performed normally. The operation is automatically terminated.

In addition, a time chart for spraying fixed foam with the sanitary cleaning device of the present embodiment is shown in FIG. 47. When the manual splash suppression switch 434 of the remote control main body 401 is pressed, the detergent pump 534 reverses for 2 seconds at the time of N2 shown in FIG. 47, then starts normal rotation at the time of N3, and the water pump 516 and the air pump 535. Is operated to supply detergent, water, and air to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed on the inner surface of the toilet bowl from the discharge port 550u of the spray nozzle 550. By spraying fixed foam on the inner surface of the toilet bowl, bubbles can be accumulated on the water surface of the toilet bowl to prevent splashing during small men's use.

The difference between the time chart for fixed foam spraying shown in FIG. 47 and the time chart for rotary foam spraying described above with reference to FIG. 45 is that the spray nozzle drive unit is used for rotary foam spraying. While the direction of the discharge port 550u was rotationally driven by the 550a, the spray nozzle drive unit 550a sprays the fixed foam while being fixed without rotationally driving the direction of the discharge port 550u when spraying the fixed foam. It is a point. The time chart of FIG. 47 is the same as the time chart of FIG. 45 except for the above, and the description overlapping with FIG. 45 will be omitted.

Regarding the origin position, stop position, and end position in FIGS. 45 to 47, for example, in FIG. 37, the origin position is 0 degree (directly behind), the stop position is 20 degrees (clockwise), and the maximum position. The end position is shown as a position of 340 degrees (clockwise), but for example, the origin position is a position of 5 degrees (from directly behind to clockwise), and the stop position is a position of 60 degrees (from directly behind to clockwise). Further, the end position may be a position of 300 degrees (clockwise).

When the fixed foam spraying instruction of FIG. 47 is issued, the spray nozzle drive unit 550a immediately stops the discharge port 550u in the direction of the discharge port 550u at a stop position of about 60 degrees clockwise from directly behind. Fixed foam is sprayed on. In this way, the spray nozzle 550 moves immediately after the fixed foam spraying is instructed in a state where the spray nozzle drive unit 550a is driven and the direction of the discharge port 550u is waited in advance at a position of about 60 degrees, which is the stop position. It is possible to immediately discharge the cleaning foam to the inner surface of the toilet bowl without any operation, and quickly form the foam height necessary for suppressing splashes on the water surface in the toilet bowl by the time the male small use is started. In particular, by setting the direction of the discharge port 550u at the stop position to a position of 50 to 70 (about 60) degrees, which hits the slope of the inner surface of the toilet bowl and the cleaning foam that hits the slope flows down to the water surface so as to rotate on the inner slope of the toilet bowl. , Cleaning foam can be quickly formed on the entire water surface.

Further, in the sanitary cleaning device of the present embodiment, the rotary foam spraying described with reference to FIG. 45 is automatically applied not only when the manual foam coat switch 433 of the remote controller main body 401 is pressed, but also after stool, that is, after using the toilet. It can be set to be sprayed with rotating foam. Further, it can be set so that the rotating foam is automatically sprayed at regular intervals. By automatically spraying rotating foam after using the toilet or at regular intervals, it is possible to make it easier for the inner surface of the toilet bowl to get dirty and to remove the dirt more easily. In addition, by automatically spraying the rotating foam at regular intervals, it is possible to suppress dirt, especially ringing, in the vicinity of the waterline in the toilet bowl.

In the sanitary cleaning device of the present embodiment, when the automatic operation setting for spraying rotating foam after using the toilet is set, the seating sensor 330 detects when the user stands up from the toilet seat 300, and about 60 seconds later, about 15 seconds. Rotating foam is sprayed. For men who are not seated on the toilet seat, when the toilet seat 300 is closed, the toilet seat open / close sensor 331 detects it, and after about 60 seconds, rotating foam is sprayed for about 15 seconds.

After about 60 seconds, the setting can be changed to about 10 seconds, 25 seconds, etc. by the switch of the remote controller main body 401, and the rotary foam spraying is started after the user stands up from the toilet seat. It is possible to adjust the time until it reaches the time that suits the usage of the user. In addition, the rotation foam spraying time of about 15 seconds can be changed to 10 seconds, 25 seconds, etc. by the switch of the remote controller main body 401, and the amount of foam to be accumulated can be adjusted according to the size of the toilet bowl. Can be done.

Further, in the sanitary cleaning device of the present embodiment, the fixed foam spraying described with reference to FIG. 47 is automatically sprayed with the fixed foam not only when the manual splash suppression switch 434 of the remote controller main body 401 is pressed but also when the toilet seat is opened. Can be set to. When the toilet seat 300 is opened during men's small use, fixed foam is automatically sprayed, so that it is possible to suppress jumping during men's small use.

In the sanitary cleaning device of the present embodiment, when the toilet seat 300 is opened, the fixed foam is sprayed for about 15 seconds immediately after the toilet seat 300 is opened, when the automatic operation setting is set to spray the fixed foam when the toilet seat is opened. ..

The fixed foam spraying time of about 15 seconds can be changed to 10 seconds, 25 seconds, etc. by the switch of the remote controller main body 401, and the amount of foam to be accumulated is adjusted according to the size of the toilet bowl. can do.

FIG. 48 shows a configuration for selecting and setting the automatic operation of the fixed foam spraying and the rotary foam spraying. Each time the automatic selection setting switch 236 of the operation unit 210 is pressed, a favorite setting can be selected. Beside the automatic selection setting switch 236, an automatic rotary spray lamp 236a after use, an automatic rotary spray lamp 236b at regular time intervals, and an automatic fixed foam spray indicator lamp 236c when the toilet seat is opened are arranged, and the automatic selection setting switch of the operation unit 210 is arranged. Each time 236 is pressed, the settings for the three types of automatic operation can be changed in the direction indicated by the arrow in FIG. 48.

After use, the automatic rotary spray lamp 236a, the automatic rotary spray lamp 236b at regular intervals, and the automatic fixed foam spray indicator lamp 236c when the toilet seat is opened are all off. Is shown. From this state, when the automatic selection setting switch 236 is pressed once, it becomes the state of H1 in which only the automatic rotation spray lamp 236a is lit after use. In this way, each time the automatic selection setting switch 236 is pressed, the setting can be changed to H2, H3 ... H6, and in H7, all three types of automatic operation can be turned on. In the lamp display of FIG. 48, the ○ mark indicates the setting “OFF” state when the lamp is off, and the ● mark indicates the setting “OFF” when the lamp is on.
Indicates the "on" state.

For example, in the case of H2, H4, H6, and H7, which are set to automatically operate the rotary foam spraying at regular time intervals in FIG. 48, the rotary foam spraying shown in the time chart of FIG. 45 is automatically performed approximately every 3 hours. It is possible to suppress dirt, especially foaming, near the waterline in the toilet bowl.

It should be noted that the above-mentioned about every 3 hours can be changed to about every 6 hours, about 12 hours, about 24 hours, etc. by the switch of the remote controller main body 401, and the number of automatic operations when absent for a long period of time It can be adjusted according to the convenience of the user, such as wanting to reduce.

(Embodiment 2)
Further, FIG. 51 shows a perspective view of the sanitary cleaning device according to the second embodiment. Further, FIG. 52 shows a schematic cross-sectional view of the sanitary cleaning device according to the second embodiment. The sanitary cleaning device of the second embodiment is a so-called toilet bowl integrated sanitary cleaning device in which the toilet bowl 110 and the main body 200 are integrally configured. The sanitary cleaning device of the first embodiment was a so-called retrofit type sanitary cleaning device in which the main body 200 was later installed on the toilet bowl separately from the toilet bowl 110.

The sanitary cleaning device of the second embodiment also has a configuration in which the foam spraying operation is performed in the same manner as the sanitary cleaning device of the first embodiment.

The difference between the sanitary cleaning device of the second embodiment and the sanitary cleaning device of the first embodiment is that after using the toilet, the flush switch 910 of the remote controller 400, which is an operation unit, is used to wash the toilet bowl after stool or after defecation. The point is that it is equipped with a flush valve 930 that can wash away the toilet bowl.

When the flush switch 910 is pressed after using the toilet, the control unit 130 in the main body 200 opens the flush valve 930 by the ON signal of the flush switch, and the water discharged from the toilet spout 940 moves around the rim 950 on the upper part of the toilet. While turning, it flows to the lower part of the toilet bowl and is discharged from the toilet bowl drain port 960. At the time of cleaning the toilet bowl in which water is discharged from the toilet bowl spout 940, the control unit 130 is configured to discharge cleaning foam from the discharge port 550u of the spray nozzle 550 toward the water in the vicinity of the toilet bowl spout 940.

The water discharged from the toilet spout 940 flows toward the water near the toilet spout 940 while swirling around the rim 950 on the upper part of the toilet, and the cleaning foam is discharged from the discharge port 550u of the spray nozzle 550. As a result, the rim 950, which could not be sufficiently reached by the foam spraying of the sanitary cleaning apparatus of the first embodiment, can be vigorously washed away with water mixed with cleaning foam to a closer vicinity.

To explain the reason, first, the water discharged from the toilet spout 940 gradually flows to the lower part of the toilet while swirling along the rim 950 on the upper part of the toilet. Since the cleaning foam is sprayed from the discharge port 550u of the spray nozzle 550 toward the water near the discharged toilet spout 940, the cleaning foam rides on the water discharged from the toilet spout 940 and mixes with the water. It gradually flows to the lower part of the toilet while turning along the rim 950 on the upper part of the toilet. Therefore, from the vicinity of the rim 950 on the upper part of the toilet bowl to the lower part where the drainage port 960 is located, the inside of the toilet bowl can be washed widely with water mixed with washing foam, and dirt can be suppressed.

In the above description, when cleaning the toilet bowl, it is assumed that the cleaning foam is discharged from the spray nozzle 550 toward the water near the toilet spout 940, but the cleaning foam is sprayed not only near the toilet spout 940 but also on the inner surface of the toilet bowl. You may.

When cleaning the toilet bowl after using the toilet, the control unit 130 opens the flush valve 930 by the ON signal of the flush switch, and the cleaning foam is sprayed from the spray nozzle 550 toward the water on the inner surface of the toilet bowl or near the toilet spout 940. As for the timing of spraying, the cleaning foam is sprayed from the spray nozzle 550 at the same time as the water is discharged from the toilet spout 940, or the cleaning foam is sprayed from the spray nozzle 550 after the water starts to be discharged from the toilet spout 940. Regardless of whether it is sprayed, the effect of vigorously rinsing the toilet bowl with water mixed with washing foam can be obtained as well.

Further, at the time of cleaning the toilet bowl, the control unit 130 first opens the flush valve 930 after the spraying nozzle 550 precedes the flushing to the inner surface of the toilet bowl by the ON signal of the flush switch, and discharges water from the toilet bowl spout 940. A higher cleaning effect can be obtained by cleaning the toilet bowl while spraying cleaning foam from the spray nozzle 550 toward the inner surface of the toilet bowl or the water near the toilet spout 940.

Further, after cleaning the toilet bowl after defecation, the control unit 130 keeps the flush valve 930 closed and rotates the direction of the discharge port 550u of the spray nozzle 550 while rotating the cleaning foam as in the first embodiment. The rotary foam spraying operation is performed. As a result, a foam film can be formed from the front surface of the toilet bowl to the inner surface behind the toilet bowl to suppress dirt adhesion.

In addition to the user operating the flash switch 910 of the remote controller 400, the above-mentioned toilet bowl cleaning is automatically executed by detecting that the user has left the toilet seat 300. Is.

As described in the first embodiment, the seating sensor 330 for detecting that the user is seated on the toilet seat 300 is provided, and the seating sensor 330 detects that the user has left the toilet seat 300.

In the second embodiment, the control unit 130 automatically starts cleaning the toilet bowl about 30 seconds after the user leaves the toilet seat 300. The time is not limited to about 30 seconds, and may be, for example, about 20 seconds or 60 seconds.

With the configuration in which the user detects that the user has left the toilet seat 300 and automatically cleans the toilet seat, the user may forget to operate the flash switch 910 of the remote controller 400 after stool. The toilet seat is automatically washed and the toilet bowl can be kept clean.

When the user presses the flush switch 910, which is a toilet seat cleaning switch, to instruct the toilet bowl cleaning, the control unit 130 does not perform automatic toilet bowl cleaning even if the user detects that the user has left the toilet seat 300. Is.

As a result, unnecessary washing of the toilet bowl can be prevented, and wasteful use of the detergent used for foam spraying can be prevented.

As described above, in the sanitary cleaning device of the second embodiment, the flush valve 930 is opened by the ON signal of the flush switch 910, and the water discharged from the toilet spout 940 swirls around the rim 950 on the upper part of the toilet. A toilet bowl 110 that flows to the bottom and is discharged from the toilet bowl drain port 960, a main body 200 installed in the toilet bowl 110, a foam generator 560 that generates cleaning foam, and a spray nozzle that discharges cleaning water or cleaning foam onto the inner surface of the toilet bowl. The flush is provided with 550, a spray nozzle driving unit 550a for driving the spray nozzle 550, a control unit 130 for controlling these operations, and an operation unit for instructing and setting the control unit 130. When the flush valve 930 is opened by the ON signal of the switch 910 and water is discharged from the toilet spout 940, the cleaning foam is discharged from the spray nozzle 550 toward the inner surface of the toilet 110 or the water near the toilet spout 940. Depending on the configuration, it is possible to wash the inside of the toilet bowl with water mixed with washing bubbles so as to spread widely, and it is possible to suppress dirt.

Further, after the toilet bowl cleaning is completed, the control unit 130 sprays the cleaning foam onto the toilet bowl inner surface while rotating the direction of the discharge port 550u of the spray nozzle 550 in a state where the flush valve 930 is closed. A foam film can be formed to suppress dirt adhesion.

As described above, in the sanitary cleaning device according to the present invention, the flush valve is opened by the ON signal of the flush switch, and the water discharged from the toilet spout flows to the lower part of the toilet while swirling near the rim of the upper part of the toilet. A toilet bowl discharged from a drain port, a main body installed in the toilet bowl, a foam generator that generates cleaning foam, a spray nozzle that discharges cleaning water or cleaning foam onto the inner surface of the toilet bowl, and a spray that drives the spray nozzle. It includes a nozzle drive unit, a control unit that controls these operations, and an operation unit that sets instructions to the control unit. The control unit opens the flush valve by the ON signal of the flash switch, and water is discharged from the toilet spout. With the configuration in which the cleaning foam is discharged from the spray nozzle toward the inner surface of the toilet bowl, the inside of the toilet bowl can be cleaned with water mixed with the cleaning foam so that the inside of the toilet bowl can be widely distributed, and dirt can be suppressed. It can also be applied to the use of equipment equipped with other spray nozzles.
