As a result, since the air in the heat exchanger 700 can be removed and the wash water can be reliably filled with water, it is possible to reliably prevent the heat exchanger 700 from being heated and improve safety and durability. can do. In addition, by reliably supplying the wash water to the water pump 516, which is the water discharge amount varying means, to fill it up, the water pumping function of the water pump 516, which is the water discharge amount varying means, can be reliably activated.

At the time P3 when the energization of the water shutoff solenoid valve 514 is stopped, the control unit 130 starts driving the water pump 516, which is a water discharge amount varying unit, and operates the flow control valve 517 to wash the bottom of the nozzle unit 820. The supply of cleaning water to the flow path 835 is started.

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

The washing water supplied to the hip washing flow channel 835 is ejected from the hip washing outlet 834. The ejected cleaning water passes through the ejection opening 844 and is reflected by 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 time P5, which is 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 to advance the nozzle unit 820 from the storage position to the butt cleaning position. During the movement from the storage position to the hip 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 inside of the nozzle cover 840, and the ejected cleaning water is cleaned from the inner surface of the nozzle cover 840 and then discharged from the drain port 845 to the outside of the nozzle cover 840. Spill to. During that time, the nozzle portion 820 is warmed by the wash water, and it is possible to prevent the cold water from spouting and causing discomfort during the hip cleaning performed later.

At time P6 when the nozzle unit 820 reaches the butt cleaning position, the control unit 130 switches the flow control valve 517 to start supplying the cleaning water to the butt cleaning channel 835. The washing water supplied to the hip washing channel 835 is jetted from the hip washing spout 834 and passes through the jet opening 844 to wash the user's local area. The ass washing operation is continued until time 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 incoming water temperature sensor 630 and the hot water temperature sensor 730.

The water level of the sub-tank 600 is lowered by continuing the driving of the water pump 516 which is the water discharge amount varying means, and the control unit 130 energizes the water shutoff solenoid valve 514 at time P7 when the water level detection sensor 620 detects the lower limit water level. Is started, and energization is continued until time P8 when the water level detection sensor 620 detects the upper limit water level.

At time P8 when the upper limit water level is detected, the control unit 130 stops energizing the water shutoff solenoid valve 514 and starts time measurement, and then measures the elapsed time until time P9 when the water level detection sensor 620 detects the lower limit water level. To do. At the time 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 with the flow rate set for each cleaning strength at the time point P10 at which the calculation is completed, the output of the water pump 516, which is the water discharge amount varying means, is adjusted to correct the flow rate of the cleaning water.

At a time point P11 when the operation of stopping the cleaning of the operation unit 210 or the remote controller 400 is performed, the water pump 516, which is the water discharge amount varying unit, and the heat exchanger 700 are de-energized, and the nozzle device 800 causes the cleaning nozzle drive unit. The driving of 860 is started, and the nozzle portion 820 retracts from the hip cleaning position to the storage position.

At time P12 when the nozzle portion 820 retracts to the storage position, the drive of the cleaning nozzle drive portion 860 of the nozzle device 800 is stopped, the water pump 516 and the heat exchanger 700 that are the water discharge amount varying means are driven again, and the nozzle portion 820 After the cleaning is started, the post-cleaning is started, and at a time point P13 when a predetermined time has elapsed, the driving of the water pump 516 which is the water discharge amount varying means and the heat exchanger 700 is stopped, and the post-cleaning is completed.

At the time point P13 when the post-cleaning of the nozzle portion 820 is completed, the water shutoff solenoid valve 514 is energized again, the washing water is supplied to the sub tank 600, and the water shutoff solenoid valve 514 is deenergized at the time point P14 when the upper limit water level is detected. A series of control of the butt cleaning is completed, and the cleaning means is in the standby state when the sub tank 600 is at the upper limit water level.

FIG. 30 shows a time chart during normal use when the washing operation is performed in the sanitary washing device in the standby state where the initial use was previously performed.

A big difference from the case of the initial use shown in FIG. 29 is that the sub-tank 600 is already full at the time P20 when the cleaning operation is performed, and that the control unit 130 remembers that the initial use is performed. is there.

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

The control from the time of performing the cleaning operation to the time of starting energization of the heat exchanger 700 is different from that in the case of the initial use described above, and the control and action operation after the time P5 when the driving of the nozzle device 800 is started. It is the same.

As described above, the sanitary washing device according to the present embodiment, in the configuration of the washing means, detects a 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, With the configuration in which the flow rate is detected by calculation, the configuration of the cleaning unit can be simplified and the cost can be reduced.

Further, by correcting the threshold value for determining the change in the output voltage between the electrodes in the water level detection with the temperature, the accuracy of the water level detection and the flow rate detection can be improved, and the sanitary washing device can be used for a wide range of water having different conductivity. Since it can be used as the washing water of the above, the range of use and usability of the sanitary washing device can be improved.

In addition, during the initial use of the sanitary washing device, water continues to flow for a predetermined time after the sub tank is filled with water, and the heat exchanger starts to be energized after the water level detection sensor has canceled the detection of the upper limit water level. By doing so, it is possible to prevent heating of the heat exchanger, which is simpler and less costly, and safer and more reliable than the commonly used means of preventing heating using a flow sensor. Can be secured.

<7> Control and action of discharge to the inner surface of the toilet by the spray nozzle FIG. 31 is a perspective view showing the appearance of the spray nozzle, FIG. 32 is a sectional view of the spray nozzle, and FIG. 33 is a sanitary washing device. 34 is a vertical sectional view showing the installation state of the spray nozzle in FIG. 34, FIG. 34 is a front view showing the installation state of the spray nozzle in the sanitary washing device, and FIG. 35 is the installation position of the spray nozzle in the sanitary washing device and the rotation angle of the outlet of the spray nozzle. FIG. 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 includes a rotary nozzle 550d, an O-ring 550e, and an O-ring 550f which are rotatable in a body 550c having an inlet flow path 550b by a spray nozzle drive unit 550a which is a motor. It is a sealed structure. By using an X-ring instead of the O-ring 550f, the torque required for rotational driving can be reduced and sticking can be easily prevented, and the spray nozzle driving unit 550a, which is a motor, can be made small and have low torque. it can. The shaft 550n of the spray nozzle drive unit 550a is fitted to the rotary nozzle 550d.

The cleaning water or cleaning bubbles 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 opened 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 gives priority to arranging the buttocks cleaning nozzle 831 or the like, which is a cleaning nozzle for cleaning the human body part, in the center, and therefore the spraying nozzle 550 is arranged not on the center but on the left or right side thereof. Is.

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

At this time, since the flow control valve 517 for switching the flow path to the buttocks cleaning nozzle 831, the bidet cleaning nozzle 832, the nozzle cleaning unit 833, etc. is closed, the cleaning water from the heat exchanger 700 flows into the branch flow path 530 and the reverse flow path. It is discharged from the spray nozzle 550 to the inner surface of the toilet via the stop valve 531 and the foam tank 532.

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

As shown in FIG. 35, the distance from the spray nozzle 550 to the inner surface of the toilet 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 varying unit, according to the rotation angle of the discharge port 550u of the spray nozzle 550.

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

That is, when the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet is the longest, and the rotation angle 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 is the largest. The ejection amount (and ejection speed) from the ejection port 550u is controlled so that the output of the pump becomes small when the rotation angle that becomes close (short) is around 340°.

Therefore, when the flush water is discharged from the discharge port 550u of the spray nozzle 550 to the front of the toilet at the farthest distance, the wash water is discharged with the strongest force and reaches the inner surface in front of the toilet bowl, and the discharge port 550u of the spray nozzle 550 is discharged. When it is discharged to the rear of the toilet bowl that is the closest distance from, the wash water is discharged with the weakest force, so there is no problem such as splashing to the rear of the toilet bowl, and flush water or cleaning foam is spread on the inside of the toilet bowl in general. It can be discharged so as to reach the inside, and a water film or a foam film can be formed up to the inner surface in front of the toilet bowl to suppress the attachment of dirt.

When the user detects that the user has entered the toilet by the human body detection sensor 450, or by operating the spraying switch 417 of the operating unit 210 or the remote controller 400, so-called toilet foam spraying for spraying cleaning foam to the toilet bowl. You can When the toilet foam is sprayed by the above-mentioned toilet foam spray signal, the control unit 130 normally rotates the spray nozzle drive unit 550a while changing the output of the water discharge amount varying means 516, as shown in FIG. The direction of the outlet 550u of the spray nozzle is from the rear of the toilet to the front of the toilet to the rear of the toilet, and the spray nozzle driving unit 550a is reversed to direct the outlet 550u of the spray nozzle from the rear of the toilet to the rear of the toilet. There is a step of spraying bubbles by returning at least one reciprocating rotation operation.

As a result, the output of the water discharge amount varying means is controlled so that the cleaning foam 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 inner surface of the toilet bowl. Adhesion of dirt can be suppressed.

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

This makes it possible to cover the draft surface above the outlet of the toilet bowl with cleaning foam early in the early stage of spraying, and also to spray the cleaning foam almost all around the inner surface of the toilet bowl near the rim, and to foam from the front to the rear of the toilet bowl. A film can be formed to suppress the attachment of dirt.

The installation position of the spray nozzle 550 is located in front of the main body 200 that is 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 end 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 installed. By rotating and driving the direction of the discharge port 550u of the nozzle, it is possible to spray foam to the rear of the toilet, and to form a foam film from the front of the toilet to the inner surface of the rear to prevent dirt from adhering.

Note that, in the above description, forward rotation is shown as clockwise rotation when viewed from above in FIG. 35, and reverse rotation is shown as counterclockwise rotation. However, forward rotation is clockwise rotation and counterclockwise rotation is counterclockwise rotation, 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 during spraying is the forward rotation, and the direction in which it returns is called reverse rotation.

In the above description, the configuration is such that the output of the water pump 516, which is the water discharge amount varying means, is controlled at the time of spraying the rotating foam for spraying the cleaning foam into the toilet. Even if the output of the water pump 516, which is a water amount varying means, is not changed, the spray nozzle 550 is configured as described below to form a foam film from the front surface of the toilet bowl to the inner surface of the rear surface thereof to suppress the adhesion of dirt. You can

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

As described above, when the cleaning foam is sprayed from the spray nozzle to the toilet bowl, the direction of the discharge port 550u of the spray nozzle is rotationally driven about the rotation axis Ax by the spray nozzle driving unit 550a. With the rotation of the spray nozzle, the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet changes, but as the height of the discharge port 550u of the spray nozzle 550 changes with the rotation, cleaning bubbles are sprayed. A foam film can be formed from the front of the toilet bowl to the inner surface near the rear rim with a spraying trajectory as depicted by the left-handed dashed arrow in FIG. 35, and the adhesion of dirt can be suppressed from the front surface of the toilet bowl to the rear surface. You can Since the output of the water pump 516, which is the water discharge amount varying means, does not change when the rotary foam is sprayed, when the rotary foam is sprayed in the counterclockwise direction, the same trajectory as the counterclockwise dashed arrow in FIG. 35 is reversed. It is sprinkled as follows.

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 of the left-right direction shown in FIG. 34 is 10 degrees. Further, the height position of the discharge port 550u of the spray nozzle 550 is set so as to be below the upper end surface of the toilet 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 flush water or the flush water can be supplied even if the distance to the front, side, or rear of the toilet differs. The cleaning bubbles can be discharged so as to reach a wide area on the inner surface of the toilet bowl, and a water film or a foam film can be formed on a wide area on the inner surface of the toilet bowl to suppress the adhesion of dirt.

The operation unit 210 or the remote controller 400 may be provided with a level changeover switch that can adjust the level (average level) of the pump output to be increased or decreased. As a result, even if the size of the toilet bowl is different, wash water or washing bubbles can be discharged so that it reaches 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 prevent dirt from adhering. You can do it.

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. You may make it change the speed of the part 550a. By changing the output of the pump (water pump 516, which is a water discharge amount varying means), the ejection force can be changed to reach the inner surface of the toilet bowl that is far away, and in addition to suppressing the scattering on the inner surface of the toilet bowl that is near, By changing the speed of the spray nozzle driving unit 550a according to the rotation angle of the outlet 550u, the spray density can be made more uniform.

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

For example, to explain with the rotation angle shown in FIG. 35, the wash water or wash bubbles that are sprayed in front of the toilet bowl at a rotation angle of 160°, which is the farthest distance from the discharge port of the spray nozzle, disperse and scatter density. When the water is discharged to the front of the toilet bowl, the spray nozzle has the slowest rotation speed, the spray density is increased, and the rotation angle that is the closest distance from the discharge port of the spray nozzle is around 340°. When discharged to the rear, the spray nozzle 550 has the highest rotation speed and the spray density is thinned, so that the distribution of the wash water or wash bubbles sprayed on the inner surface of the toilet bowl can be made more uniform, and the adhesion of dirt can be suppressed. You can do it.

That is, the control unit 130 changes the speed of the spray nozzle driving unit 550a in accordance with 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 is such that the distance to the inner surface of the toilet bowl is long. The speed of the spray nozzle drive unit 550a is small when the rotation angle is in the front of the toilet bowl, and the distance to the inner surface of the toilet bowl is short. By increasing the speed of the spray nozzle drive unit when the rotation angle is in the rear of the toilet bowl, the front and side of the toilet bowl are On the other hand, even if the distance to the rear is different, the washing water or washing bubbles can be evenly ejected to the inner surface of the toilet bowl, and a water film or foam film is evenly formed up to the inner surface in front of the toilet bowl to prevent dirt from adhering. Can be suppressed.

The control unit 130 detects the entry of a person by the human body detection sensor 450, and then the spray nozzle 550 sprays cleaning bubbles on the inner surface of the toilet bowl. In so-called toilet bubble spraying, the spray nozzle driving unit 550a reciprocates the rotary nozzle 550d at least once. While rotating, it sprays bubbles and automatically stops. Accordingly, 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 structure may be such that spraying is stopped from the rotating outlet 550u to the inner surface of the toilet as many times as it is spread, and it is not limited to one reciprocating rotary drive. Can be selectively set by the operation unit 210 or the remote controller 400.

Further, when the spray nozzle 550 sprays the wash water or the wash foam on the inner surface of the toilet bowl, the rotary nozzle 550d of the spray nozzle 550 is configured to reciprocally rotate as shown in FIG. 36. Like the configuration in which the rotary nozzle 550d is rotated all around in either one of the right direction and the left direction, the spray direction of the cleaning water or the cleaning foam is not always the same direction, but the rotating nozzle 550d is reciprocally rotated to reverse the direction. By spraying from one direction and spraying from two directions by this forward and reverse rotation, the so-called spray dropout area can be further reduced, and spraying can be spread more easily. You can do it.

In the chart of FIG. 36, the rotation angle 0° corresponding to the rear side of the toilet bowl is normally rotated from the rotation angle 0° to 340°, and then stopped, and then the rotation is reversed from the rotation angle 340° to the rotation angle 0°, and then stopped after the reciprocating rotation. The action to be performed is shown. The rotation nozzle 550d of the spray nozzle 550 is provided with a rotation restricting portion (not shown) whose rotation range is restricted by a mechanical stopper from a rotation angle of 0° to a rotation angle of 340°.

The rotation restricting part (not shown) is a spray nozzle driving part 550a when a protrusion formed on a part of the outer periphery of the rotating nozzle 550d rotates together with the rotating nozzle 550d and comes into contact with the rotation restricting wall of the body 550c. Even if the motor tries to rotate the rotary nozzle 550d, the rotary nozzle 550d is mechanically abutted, so that the motor slips and idles only, and the rotary nozzle 550d cannot rotate.

As described above, by providing the rotation restricting portion (not shown) for restricting the rotation range and reciprocally rotating the spray nozzle 550 within the rotation range not restricted by the rotation restricting portion, the spray nozzle 550 is reciprocated from the opposite direction. By spraying and spraying in two directions by the forward and reverse rotations, so-called spray slip-out portions can be further reduced, and sprays can be spread more easily, so it is possible to suppress dirt adhesion with a small number of spraying times (time). ..

Further, the spray nozzle drive unit 550a is configured by a motor, and the origin of the rotational position of the spray nozzle drive unit can be recognized at the position where the rotation restricting unit abuts, and the accuracy of the rotation angle position and the rotation speed is high. Spraying with very little variation is possible.

Note that, as described in the water circuit configuration in FIG. 6, the branch flow passage 530 in the wash water supply flow passage 690, which is branched between the water pump 516 and the flow control valve 517, which is the water discharge amount varying means, is opened and closed. The bubble tank 532 is connected via the valve 530a and the check valve 531 so as to be supplied with washing water, and the spray nozzle 550 is connected downstream of the bubble tank 532. A detergent tank 533 for supplying detergent to the foam tank 532 and a detergent pump 534 are connected to the foam tank 532, and an air pump 535 for supplying air to the foam tank 532 to produce cleaning foam is provided.

By the way, when the control unit 130 opens the opening/closing valve 530a, the wash water from the heat exchanger 700 is sent by the water pump 516, which is a discharge amount varying means, so that wash water or wash bubbles are discharged from the spray nozzle 550. It At that time, in accordance with the increase and decrease of the outputs of the water pump (pump) 516 and the air pump 535, which are the water discharge amount varying means, the discharge amount and the discharge momentum of the cleaning water or the cleaning bubbles discharged from the spray nozzle 550 (the discharge speed and the discharge speed and The discharge pressure) is increased or decreased.

The configuration in which the opening/closing valve 530a is provided in the branch flow passage 530 may be a configuration in which a flow passage switching valve is provided at the branch portion between the branch flow passage 530 and the wash water supply flow passage 690.

The user can select and instruct by the operating unit 210 of the main body 200 or the remote controller 400 whether to spray the cleaning water or the cleaning foam from the spray nozzle 550. A foam tank 532 is provided between the opening/closing valve 530a and the spray nozzle 550 to generate cleaning foam, and the cleaning foam is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl. The effect of suppressing the adhesion of dirt can be further enhanced by forming a foam film of washing foam containing a detergent instead of merely forming a water film by spraying water or warm water. Further, the foam film formed by the cleaning foam containing the detergent can suppress an unpleasant odor and improve the comfort of a visually clean image.

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

It should be noted that the user arbitrarily selects in advance which spray water or cleaning foam is sprayed from the spray nozzle 550 to the inner surface of the toilet by the spray selection switch (not shown) of the operation unit 210 or the remote controller 400. be able to.

Further, the control unit 130 has a cedar warning mode that can be selected and instructed by a switch button of the operation unit 210 or the remote controller 400, and supplies the detergent in the detergent tank 533 of the foam generating section 560 to the foam tank 532 in the cedar warning mode. The opening/closing valve 530a may be opened with the detergent pump 534 stopped, and the cleaning water may be supplied to the foam tank 532 by the water discharge amount varying 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 the cleaning water, so that the path and the spray nozzle 550 can be prevented from being clogged due to the adhesion of the detergent, and the rotation failure due to the adhesion of the detergent to the spray nozzle 550 can be prevented. .. Also, the inner surface of the toilet bowl can be rinsed.

That is, since the detergent pump 534 is stopped during this rinsing operation, the cleaning water is sent to the foam tank 532 without being supplied with the detergent, so that the path from the foam tank 532 to the spray nozzle 550 is rinsed with the cleaning water. In addition to being able to clean, the inner surface of the toilet bowl can be rinsed with flush water.

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

The user can perform rinsing at any time by operating the cedar switch 223 of the operation unit 210 in the cedar-issued mode.

It should be noted that a cedar lamp 223a such as an LED is provided near the cedar switch 223 of the operation section 210 for setting the cedar announcement mode, and the control section 130, when a predetermined time such as 20 days has passed since the last rinsing, With the configuration in which the cedar lamp 223a automatically blinks, forgetting to rinse can be prevented.

When the cleaning bubbles are sprayed from the spray nozzle 550 to the inner surface of the toilet, the control unit 130 responds to the rotation angle of the discharge port 550u of the spray nozzle 550 in the same manner as the pump output of FIG. 36 described above. The output of 535 may be changed. As a result, even if the distance to the front, side, or rear of the toilet bowl is different, the cleaning bubbles can be discharged so as to reach the entire inner surface of the toilet bowl, and a foam film is formed up to the inner surface of the toilet bowl front to prevent dirt adhesion. Can be suppressed.

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

In addition, a stain detecting unit (not shown) for detecting stains on the toilet bowl by an image element or the like is further provided, and the control unit 130 partially reciprocates the portion where the stain remains to further scatter the stains. The suppression 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 of discharge by the spray nozzle when the toilet seat is open/non-seated state Next, when the user is not seated on the toilet seat 300 as in male urine, the toilet seat 300 is opened almost vertically. 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 position and the toilet seat 300 is open, the signal from the toilet seat opening/closing detection unit 331 is the toilet seat open state, and the signal from the seating detection unit 330 is the non-seated state. When the spraying switch 417 is pressed by the user, as shown in FIG. 37, the control unit 130 causes the discharge port 550u of the spraying nozzle 550 to face the discharge port 115 of the toilet bowl (in the present embodiment, in the case of FIG. As shown in the chart of FIG. 37, after the spray nozzle driving unit 550a is rotationally driven and stopped up to a rotation angle of the discharge port 550u of about 150°), the water discharge amount varying unit 516 is controlled with a medium output to control the discharge amount. As shown by the arrow, the cleaning bubbles are discharged to the outlet 115 of the toilet for a predetermined time (8 seconds in the present embodiment). The discharged cleaning bubbles cover the water surface above the discharge port 115 of the toilet 110, that is, the upper part of the so-called draft surface in the toilet with the foam.

According to the rotary foam spraying announcement (foam coat) mode of the control unit 130 described in the section <7>, the cleaning foam is sprayed in the toilet while rotating the direction of the discharge port 550u of the spray nozzle 550. The <8> item is fixed foam spraying in which the cleaning foam is sprayed in the toilet while the direction of the discharge port of the spray nozzle is fixed by the fixed foam spraying announcement (flue suppression) mode of the control unit 130.

As described above, in the state where 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 operation unit 210 or the spray switch of the remote controller 400 is a manual switch. When the splash suppression switch 434 is operated, as shown in FIG. 37, the control unit 130 causes the discharge port 550u of the spray nozzle 550 to face the rear of the toilet (see the chart of FIG. 37 in the present embodiment. As shown in FIG. 37, the spray nozzle drive unit 550a is rotationally driven to a stop until the rotation angle of the discharge port 550u is about 20° and stopped, and then the water discharge amount varying means 516 is controlled with a high output to wash bubbles. Is discharged to the rear of the toilet for a predetermined time (8 seconds in the present embodiment).

In this case, as shown in the cross-sectional view of FIG. 33, the discharge port 550u of the spray nozzle 550 is opened in the direction of an angle α degrees with respect to the rotation axis Ax of the spray nozzle 550, and thus the discharge port of FIG. Direction: Cleaning bubbles are 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, the water discharge amount varying means 516 is controlled with a high output, and the cleaning foam is in the water surface above the outlet 115 in the toilet and in the toilet. The upper portion of the water line can be quickly covered with bubbles, and the cleaning bubbles can suppress odor and adhesion of dirt near the water line of the toilet bowl. Further, when the urine falls near the water surface in the toilet bowl, it is possible to suppress the rebound to the surroundings due to the cushioning effect of the foam covering the water surface. That is, a large amount of bubbles can be sprayed quickly in the direction in which the spray nozzle 550 is fixed to form bubbles on the upper surface of the water surface in the toilet bowl to prevent splashing of urine.

In the present embodiment, when the user operates the manual splash suppression switch 434 of the remote controller 400 during male urine, the control unit 130 enters the fixed foam spraying announcement (splash suppressing) mode and the discharge port 550u of the spray nozzle 550. After the spray nozzle driving unit 550a is rotationally driven and stopped to a position where the direction is toward the discharge port 115 of the toilet, the water discharge amount varying unit 516 is controlled with a high output and the cleaning foam is discharged toward the rear of the toilet. However, the position where the cleaning bubbles are fixedly sprayed may be on the front side, the center, or the rear side of the toilet near the outlet 115.

That is, by quickly covering the water surface and the upper part of the toilet water line with foam for a short time of a few seconds after the cleaning foam starts to be discharged, it is possible to suppress the splashing of urine and to prevent the vicinity of the water line in the toilet bowl. It is possible to suppress the adherence of dirt on the upper part thereof.

According to the fixed foam spraying announcement (flue suppression) mode, in the fixed foam spraying in which the cleaning foam is sprayed in the toilet while the direction of the discharge port of the spray nozzle is fixed, in FIG. 37, the water discharge amount varying means 516 is controlled with a high output. Although the cleaning foam is discharged toward the outlet 115 of the toilet, the output of the water pump 516, which is the water discharge amount varying means, does not change, as in the case of the rotating foam spraying described in the above section <7>. The output, that is, the output of the water pump 516, which is the water discharge amount varying means at the time of fixed foam spraying, may remain the same as that at the time of rotary foam spraying.

As described above, the sanitary washing device according to the present embodiment is provided with the main body 200 installed in the toilet 110, the washing nozzle 831 for washing the human body, the bubble generator 560 for producing washing bubbles, and the washing water or the washing water on the inner surface of the toilet. A spraying nozzle 550 that discharges cleaning bubbles, a discharge amount varying means 516 that changes the flow rate of the cleaning water that is sent to the spraying nozzle, a spraying nozzle drive unit 550a that rotationally drives the discharge port 550u of the spraying nozzle, and a spraying nozzle. An on-off valve 530a that opens and closes a water channel to the flow path, a control unit 130 that controls these operations, and an operation unit 210 that sets instructions to the control unit. The control unit 130 directs the direction of the discharge port 550u of the spray nozzle. Rotating foam spraying warning (foam coat) mode that sprays cleaning foam into the toilet while rotating, and fixed foam spraying warning (foam suppression) that sprays cleaning foam into the toilet with the discharge nozzle 550u direction fixed. ) Mode, the cleaning foam is sprayed from the spraying nozzle 550 to the toilet bowl when the toilet foam is sprayed so that the cleaning foam is widely spread in the toilet bowl while the direction of the outlet 550u of the spraying nozzle is rotationally driven. A foam film can be formed from the front side to the rear side inside to prevent dirt from adhering to the inside of the toilet bowl and the vicinity of the water line.

In addition, by the fixed foam spraying announcement mode in which the cleaning foam is sprayed in the toilet while the direction of the discharge port 550u of the spray nozzle is fixed, the cleaning foam is quickly formed above the water surface in the toilet bowl, and the water surface above the outlet in the toilet bowl is formed. Since it can be covered with cleaning foam, the cleaning foam can suppress the unpleasant odor at the time of urine and the scattering due to the splash at the time of male urine.

Note that, as a result of a verification experiment on the effect of suppressing splashing due to splashes during male urine, as shown in FIG. 49, there is an effect that the thickness of the foam, which is the foam height, is improved from about 5 mm to the absence of foam. It was confirmed that the suppression effect became remarkable when the thickness of the bubbles was about 10 mm. That is, it is preferable that the lower limit of the thickness of the bubbles on the water surface in the toilet due to the foam application is 5 mm or more and the upper limit thereof is 50 mm or less. It should be noted that 50 mm or less is an upper limit when the height of the foam is such that the accumulated foam does not stick to the hip when the user sits on the toilet seat.

Further, in the sanitary washing device according to the present embodiment, the spray nozzle 550 is installed in the main body 200 with the rotation axis Ax of the discharge port 550u of the spray nozzle that is rotationally driven being inclined in the front-rear direction and the left-right direction. The lower side of the rotation axis Ax is inclined to the front side of the toilet 110, and the left and right direction is inclined such that the lower side of the rotation axis Ax is inclined to the cleaning nozzle 831 side. When the foam is sprayed, the distance from the discharge port 550u of the spray nozzle to the spray position is long. When the discharge port 550u faces the front of the toilet bowl, the direction of the discharge port 550u becomes high and the distance from the discharge port 550u of the spray nozzle to the spray position is increased. When the discharge port 550u faces toward the rear of the toilet bowl where the distance is short, the direction of the discharge port 550u becomes low. As described above, 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, so that the cleaning bubbles can be sprayed. Even if the output of the toilet is not changed, it is possible to form a foam film from the front of the toilet to the inner surface of the rear of the toilet to suppress the attachment of dirt.

Further, in the sanitary washing device according to the present embodiment, when the foam is sprayed from the spray nozzle 550 to the toilet 110, the control unit 130 causes the spray nozzle driving unit 550a to rotate normally so that the discharge nozzle 550u is directed toward the toilet bowl. From the rear to the front of the toilet, to the rear of the toilet, the spray nozzle driving unit 550a is reversed, and the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet to the front of the toilet to the rear of the toilet. With the configuration including the steps, when the rotating foam is sprayed from the spray nozzle 550 to the toilet bowl, the control unit 130 causes the spray nozzle driving unit 550a to rotate normally so that the direction of the spray nozzle discharge port 550u is from the rear of the toilet bowl. After reaching the rear of the toilet via the front of the toilet, the spray nozzle drive unit 550a is reversed to cause the direction of the outlet 550u of the spray nozzle to return from the rear of the toilet to the front of the toilet to the rear of the toilet at least one reciprocating rotation while washing foam. The output of the water discharge amount varying means is controlled so that the water reaches the rim of the toilet bowl, and 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 of the toilet bowl to the inner surface of the toilet bowl to suppress dirt adhesion. be able to.

In addition, the sanitary washing device of the present embodiment further includes a human body detection sensor 450 that detects the entry/exit of the user into/from the toilet room, and the control unit 130 causes the human body detection sensor 450 to detect the entry of the user into the toilet room. When the human body detection sensor 450 detects the user's entry into the toilet room, the direction of the spray nozzle 550u rotates at least one reciprocating rotation when the human body detection sensor 450 detects the user's entry into the toilet room. While being driven, it is possible to perform rotating foam spraying in which cleaning foam is sprayed to the inner surface of the toilet bowl, and it is possible to reliably form a foam film on the inner surface of the toilet bowl before use and to prevent dirt from adhering.

Further, in the sanitary washing device of the present embodiment, the control unit 130 opens the opening/closing valve 530a to supply the wash water to the foam tank 532 to which wash water is supplied by the discharge amount varying means 516, and the detergent in the detergent tank 533 to the foam tank 532. The surface of the cleaning nozzle 831 or the inner surface of the toilet bowl is equipped with a detergent pump 534 for supplying and an air pump 535 for supplying air to the foam tank, and the cleaning water or cleaning foam of the foam tank 532 is discharged from the spray nozzle 550. By discharging not only water or warm water but also cleaning bubbles containing a detergent, the cleaning effect and the effect of suppressing dirt adhesion can be enhanced. In addition, the cleaning foam containing the detergent can suppress an unpleasant odor and can improve a visually clean and comfortable feeling.

Further, in the sanitary washing device of the present embodiment, the control unit 130 has a cedar warning mode, and in the cedar warning mode, the detergent pump 534 that supplies the detergent in the detergent tank 533 of the foam generating section 560 to the foam tank 532 is stopped. In this state, the opening/closing valve 530a is opened and the cleaning water is sent to the foam tank 532 by the water discharge amount varying 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 wash water. It is possible to prevent clogging of the path and the spray nozzle 550 due to the sticking of the detergent, and rotation failure due to the sticking of the spray nozzle to the detergent. Also, the inner surface of the toilet bowl can be rinsed.

In the present embodiment, the motor is used as the spray nozzle driving unit 550a, but the spray nozzle 550 is rotated by another drive source, for example, when the cleaning foam is discharged from the discharge port 550u of the spray nozzle 550. It may be configured so as to allow it.

Further, a spray nozzle 550 for spraying cleaning bubbles near the rim of the toilet bowl and a spray nozzle 550 for spraying cleaning bubbles near the outlet 115 of the toilet bowl may be provided. The plurality of spraying nozzles 550 may be independently rotated 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 bubbles near the rim of the toilet bowl and a discharge port 550u for spraying cleaning bubbles near the discharge port 115 of the toilet bowl.

In the present embodiment, the spray nozzle 550 is configured to spray in two places near the toilet rim and near the toilet outlet 115, but in addition to near the toilet rim and near the toilet outlet 115, It may be sprayed to another position.

Further, as shown in FIGS. 34, 38 and 39, in the sanitary washing device of the present embodiment, a sleeve case 250 is integrally provided so as to project to the front of the side of the main body 200, and the sleeve portion thereof is provided. A sleeve lid 217 provided in front of the operation portion 210 arranged on the upper part of the case 250, and a transparent or semi-transparent container of the bubble generating portion 560 inside the sleeve lid 217 and at the forefront of the sleeve case 250. The detergent tank 533 which is a built-in type is built in, and the detergent liquid level confirmation window 216 for visually confirming the detergent liquid surface position of the detergent tank 533 is provided on the front surface of the sleeve case 250. Since it is possible to easily visually check the remaining amount of the detergent when the previous procedure is performed, the detergent can be replenished before the detergent runs out.

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

Further, in the sanitary washing 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. Yes, it is formed of a so-called double hose in which the tube is further covered 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 greatly expanding or bursting even when a high pressure from the detergent pump 534 is applied, and to stably spray the cleaning foam from the spray nozzle 550. ..

Incidentally, in the sanitary washing device of the present embodiment, the detergent pump hose 561 having a double hose structure is a double hose in which the outer side of the elastomer resin tube is covered with a heat shrink tube, but the material is not limited to this. Even if other materials are used, 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, the sanitary washing device according to the present embodiment is provided with the control unit 130, the spray nozzle 550, the nozzle device and the like in the main body 200, and the rear main body case 201 includes The front surface is covered with the main body case 202.
The spray nozzle 550 is installed in the front part of the rear body case 201, the front and upper parts of the spray nozzle 550 are covered with the main body case 202, and the discharge port 516e at the lower part of the spray nozzle 550 is opened to the inner surface of the toilet. It is installed in.

Note that FIG. 40 is a cross-sectional view showing the center portion of the spray nozzle 550 installed in the rear body case 201 by cutting in the front-rear direction. The cleaning bubbles discharged from the spray nozzle 550 through the discharge port 516e are normally discharged onto the inner surface of the toilet bowl as shown by the dotted line T in FIG. However, in the case where rinsing is performed by the above-mentioned cedar-issuing mode, when the cleaning water containing no detergent and free of bubbles is discharged from the spray nozzle 550 through the discharge port 516e, the dashed-dotted line S in FIG. As shown, the jet may diffuse and splatter, causing the problem of splattering out of the toilet bowl and wetting the floor.

As shown in FIG. 40, in the sanitary washing device of the present embodiment, the main body case 202 is provided with a splash guard part 550z for blocking the upward jet exceeding the upper limit from the discharge port 516e of the spray nozzle 550 with a wall and dropping it into the toilet. Has been done. The splash guard portion 550z that blocks upward jet flow exceeding the upper limit from the discharge port 516e can prevent the washing bubbles and washing water discharged from the spray nozzle 550 from spouting out of the toilet bowl and can be sprayed inside 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 splash guard part 550z that blocks an upward jet exceeding the upper limit from the discharge port 550u of the spray nozzle 550 and drops it into the toilet bowl. As a result, it is possible to prevent the cleaning bubbles and the cleaning water discharged from the spray nozzle 550 from spouting out of the toilet bowl.

Further, the scattering guard portion 550z formed on the main body case 202 not only prevents the cleaning bubbles and cleaning water discharged from the spray nozzle 550 from spouting out of the toilet bowl. The sanitary washing device is configured such that 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 washing device removed when the contractor or the user initially installs it in 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 bottom of the main body 200. The 200 may be temporarily placed on the table or on the floor.

Thus, when the main body 200 of the sanitary washing device is randomly placed on the table or the floor,
The spout guard 550z protects the discharge port 516e of the spray nozzle 550 located below the mounting surface of the main body 200 from contacting the base or the floor, and prevents the spray nozzle 550 from being damaged. 41 showing a front view of the main body 200 and FIG. 42 showing a side view of the main body 200 show the surface of the base when the main body 200 is placed. As shown in FIGS. 41 and 42, the spout guard portion 550z prevents the ejection port 516e of the spray nozzle 550 from contacting the surface of the table.

In the sanitary washing device of the present embodiment, the splash guard portion 550z is formed on the main body case 202, but the splash guard portion 550z may be formed on the body 550c of the spray nozzle 550.

FIG. 43 is a perspective view of the main body fixing plate 240 and the rear main body case 201 of the main body 200 described above. For convenience of explanation, the perspective view of the rear body case 201 omits the control unit 130, the spray nozzle 550, the nozzle device, and the like that are installed inside.
The main body fixing plate 240 is fixed to the toilet bowl by passing a mounting bolt (not shown) through the elongated hole 241 for position adjustment. Then, the main body fixing plate 240 is aligned with the center of the main body 200, the rear portion of the main body fixing plate 240 is slightly floated, and the main body 200 is slid from the toilet surface until it clicks into place. It is fixed to.

Further, when removing the main body 200 from the toilet 110, the main body 200 can be removed by pulling the main body 200 forward while pushing the main body attachment/detachment button 242 on the side of the main body 200 with a finger.

Further, as shown in FIG. 43, a magnet 243 is embedded in the resin main body fixing plate 240, and whether the main body 200 is attached to the toilet bowl 110 in the rear main body case 201, or the main body 200 is attached to the toilet bowl 110. An attachment/detachment sensor 244 that can detect whether or not it has been removed is attached.

The attachment/detachment sensor 244 is composed of a reed switch. As shown in the partial cross-sectional view of FIG. 44, the state in which the main body 200 is attached to the toilet 110 is detected by the magnet 243 of the main body fixing plate 240 and the rear main body case 201. The attachment/detachment sensor 244 has a positional relationship in which the attachment/detachment sensor 244 faces each other. Further, when the main body 200 is detached from the toilet 110, the detachment state can be detected by the detachment sensor 244 by separating the magnet 243 and the detachment sensor 244.

When the control unit 130 detects that the main body 200 is detached from the toilet 110 by the attachment/detachment 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 110, for example, a button for instructing the discharge operation from the spray nozzle 550, such as the manual foam coat switch 433 or the manual splash suppression switch 434 of the remote controller main body 401, is pressed. However, since the discharge operation from the spray nozzle 550 is not executed, it is possible to prevent a problem that the cleaning bubbles are inadvertently ejected onto the floor or a person.

In addition, the control unit 130 does not prohibit the discharge operation from the hip cleaning nozzle 831 and the bidet cleaning nozzle 832 even when the attachment/detachment sensor 244 recognizes that the main body 200 is removed from the toilet 110. As a result, even in the unlikely event that a failure occurs in the attachment/detachment sensor 244 and the main body 200 is erroneously recognized as being removed from the toilet 110, this is a basic function of the sanitary washing device, Buttocks and bidet washes that are important to can be made workable.

Further, FIG. 45 shows a time chart when the foaming treatment is carried out by the sanitary washing device of the present embodiment. When the manual foam coat switch 433 of the remote controller body 401 is pressed, the detergent pump 534 is reversed for 2 seconds at the time N2 shown in FIG. 45, and then the forward rotation is started at the time N3, and the water pump 516 and the air pump 535 are started. Is operated to supply detergent, water, and air to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl. By applying the rotating foam to the inner surface of the toilet bowl, the inner surface of the toilet bowl is less likely to become dirty and the dirt can be easily removed.

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 nozzle 550u of the spray nozzle 550 sprays bubbles while rotating in the normal direction from the stop position at the time point N3 to the end position at the time point N6, and then moves from the end position at the time point N6 to N9. While reversing to the stop position at the time, spray and return. Then, at the time of N11, the operation of the water pump 516 and the air pump 535 is automatically stopped and the rotary foaming is automatically terminated.

In addition, while the control unit 130 continuously operates the water pump 516 and the air pump 535 between N3 and N11 where the rotating bubbles are sprayed, the detergent pump 534 normally rotates from N3 to N4 and stops. Intermittent operation is performed such as normal rotation from N6 to N7 and stop, and normal rotation from N9 to N10. Experiments have revealed that intermittent operation of the detergent pump 534 is more preferable than continuous operation of the detergent pump 534 during the application of rotary foam, and the detergent, water, and air are more preferably mixed, and more stable cleaning foam can be generated. As described above, by intermittently operating the detergent pump 534 during the rotary foam spraying, stable cleaning foam can be generated. In addition, it is possible to prevent wasteful use of detergent and reduce the time and effort required for detergent supply.

By the way, in the sanitary washing device of the present embodiment, the detergent pump 534 is operated intermittently for 2 seconds during a 6-second cycle.

Further, in the time chart when performing the rotary foam spraying shown in FIG. 45, the chart of the heat exchanger 700 is drawn by a broken line, but when performing the rotary foam spraying, this is from the water pump 516 to the foam tank 532. When the temperature of the supplied water is lower than 20° C., the heating is controlled by the heat exchanger 700 so that the water temperature is about 20° C., and the supplied water is supplied to the foam tank 532. When the water temperature is low, the foaming property is deteriorated. However, by supplying the water temperature to about 20° C. by the heat exchanger 700, it is possible to generate preferable washing foam in the foam tank 532.

Further, in the time chart when performing the rotary foaming shown in FIG. 45, the detergent pump 534 is reversed from N2 to N3 immediately before the time point N3 when the rotary foaming is started. A tube pump is used for the detergent solution on the outlet side of the tube that flows back to the tube portion that was crushed by the rollers due to the last reversal, and the crushed portion is restored to a cylindrical shape and then rotates normally. 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, from N11 to time N14 when the rotary foam spraying ends, the spray nozzle driving unit 550a is driven from the stop position until it comes into contact with the origin position. Then, the rotation detection micro switch is pressed to recognize the origin position of the spraying nozzle drive unit 550a, which is a stepping motor, and then the drive is controlled by the control unit 130 to return to the stop position.

As described above, the origin resetting operation of the spray nozzle drive unit 550a causes the slipping phenomenon of the stepping motor of the spray nozzle drive unit 550a due to some increase in the rotation load, and the rotation amount cannot be driven according to the number of drive steps. Even if a deviation occurs, it is possible to correct and reset the stop position, which is the start position of the rotary foaming, and start driving. That is, it is possible to always apply the rotating foam to a stable position.

The rotation detection micro switch pushed by the origin resetting operation of the spray nozzle driving section 550a rotates until the rotation detection micro switch is pressed because detergent adheres around the discharge port 550u of the spray nozzle 550 for some reason. It is possible to detect when the drive is no longer possible. That is, when the rotation detection micro switch is pressed and no signal is obtained when the rotary bubbles are sprayed, the cedar lamp 223a can be turned on to notify the user that the cedar switch 223 should perform the cedar operation.

In the sanitary washing device of the present embodiment, the time from N3 when the rotary foaming is started to N12 when the rotary foaming is finished is set to about 15 seconds. About 15 seconds, the amount of bubbles to be accumulated can be changed to about 10 seconds, about 25 seconds, etc. according to the size of the toilet bowl.

If the time until the rotation detection micro switch is pressed is delayed by about 10% or more with respect to the set rotary foam spraying time, the cedar lamp 223a is lit and displayed so as to blink once with "chika" and "chika". , Press the cedar switch 223 to encourage the cedar operation. In the cedar operation, the heat exchanger 700 performs cleaning for about 3 minutes while flowing cleaning water heated to about 40°C. By this Susugi operation, the foam generating part 560, the spray nozzle 550, etc. are rinsed with cleaning water, and the detergent is prevented from sticking or clogging to the foam generating part 560, the spray nozzle 550, etc., and stable foam spraying is performed. You can

If the spray nozzle 550 becomes clogged with detergent or other substances, and the time until the rotation detection micro switch is pressed is delayed by about 20% or more with respect to the set rotary foam spraying time, the cedar lamp 223a will be "flickered". , “Chika, Chika” is lit and displayed so as to repeat blinking twice, and while the cedar switch 223 is pressed to perform cedar operation, it is urged to wash the vicinity of the discharge port 550u of the spray nozzle 550 with a toothbrush or the like.

Further, in the time chart when performing the rotary foaming shown in FIG. 45, the flow path switching chart shows that the washing water from the water discharge amount varying means 516 which is the water pump in the water circuit of FIG. 6 at the time points N2 to N3. The supply destination of is switched from the nozzle device 800 side to the bubble generation unit 560 side, and is switched from the bubble generation unit 560 side to the nozzle device 800 side at times N11 to N13. That is, the flow control valve 517 is closed and the open/close valve 530a is opened at the time of N2 to N3, and the open/close valve 530a is closed and the flow control valve 517 is opened at the time of N11 to N13. Instead of the opening/closing valve 530a, a flow path switching valve may be arranged at a branch point where the branch flow path 530 is branched from the wash water supply flow path 690, and the flow path switching valve may be used to switch the flow path. Good.

Further, FIG. 46 shows a time chart during the cedar operation in the sanitary washing device of the present embodiment.

When the Japanese cedar switch 223 of the operation unit 210 is pressed and the control unit 130 enters the Japanese cedar issuing mode, the supply destination of the washing water is switched from the nozzle device 800 side to the foam generating unit 560 side at the time points N2 to N3. Then, for about 2 minutes from N3 to N8, the detergent pump 534 remains stopped and the wash water heated to about 40° C. by the heat exchanger 700 is discharged to the foam tank by the water discharge amount varying means 516 which is a water pump. Water is sent to 532 and discharged from the spray nozzle 550.
Further, for about 1 minute from N8 to N10, in addition to the wash water heated to about 40° C., an air pump 535 for sending air to the foam tank 532 is operated to perform rinse washing.

In this way, during the sugi operation for rinsing and cleaning, first, only the cleaning water is supplied, and the air pump 535 is activated from the middle to rinse the air while adding air, so that the bubbles are left 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 cleaning water, and then the air pump 535 also applies the force of bubbles to rinse the residual detergent component to a slight residual amount. Therefore, effective rinsing can be performed in a short time.

After rinsing and washing for about 3 minutes from N3 to N10, in N10 to N14, the detergent pump 534 is reversely rotated in the normal direction to perform the standby operation so that the rotary foaming and the fixed foaming can be normally performed. The operation is automatically terminated.

Further, FIG. 47 shows a time chart when the fixed foam is sprayed by the sanitary washing device of the present embodiment. When the manual splash suppression switch 434 of the remote controller body 401 is pressed, the detergent pump 534 is reversed for 2 seconds at the time point N2 shown in FIG. Is operated to supply detergent, water, and air to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl. By fixing bubbles on the inner surface of the toilet bowl to collect bubbles on the water surface of the toilet bowl, it is possible to suppress splashing when using men's toilet.

The difference between the time chart when performing fixed foam spraying shown in FIG. 47 and the time chart when performing rotary foam spraying described above with reference to FIG. 45 is that the spraying nozzle drive unit is used when performing rotary foaming. While the direction of the discharge port 550u is rotationally driven by the 550a, when performing the fixed bubble spraying, the spray nozzle driving unit 550a is not rotationally driven in the direction of the discharge port 550u but is fixed and sprays the fixed bubble. It is a point. The time chart of FIG. 47 is the same as the time chart of FIG. 45 except for that, and the description overlapping with FIG. 45 is omitted.

Note that, regarding the origin position, the stop position, and the extreme end position in FIGS. 45 to 47, for example, in FIG. 37, the origin position is a position of 0 degrees (directly behind), the stop position is a position of 20 degrees (clockwise), and the most extreme position. Although the end position is shown as a position of 340 degrees (clockwise), for example, the origin position is a position of 5 degrees (clockwise from right behind) and the stop position is a position of 60 degrees (clockwise from right behind), Further, the extreme end position may be a position of 300 degrees (clockwise).

In the case of fixed foam spraying in FIG. 47, when a fixed foam spraying instruction is issued, the spray nozzle drive unit 550a immediately stops the direction of the discharge port 550u at a stop position of about 60 degrees clockwise from right behind. Fixed foam is sprayed on. As described above, the spray nozzle driving unit 550a is driven to stand by the discharge port 550u at the stop position of about 60 degrees in advance, and the spray nozzle 550 moves immediately after the fixed foam spray is instructed. Immediately without operating, cleaning bubbles can be immediately discharged to the inner surface of the toilet bowl, and the bubble height required for suppressing the splash can be quickly formed on the water surface in the toilet bowl before the men's urination is started. In particular, by setting the direction of the discharge port 550u at the stop position to a 50 to 70 (about 60) degree position where it hits the slope of the inner surface of the toilet bowl and the cleaning bubbles that hit the slope flow down to the water surface so as to rotate the inner surface of the toilet bowl. , It is possible to quickly form a cleaning foam on the entire water surface.

In addition, the sanitary washing device of the present embodiment automatically applies the rotary foam spray described in FIG. 45 not only when the manual foam coat switch 433 of the remote controller body 401 is pressed, but also after the toilet, that is, after using the toilet. It can be set to be sprinkled on a rotating foam. Further, it is possible to set so that the rotating bubbles are automatically sprayed at regular intervals. By automatically spraying the rotating foam after using the toilet or at regular intervals, it is possible to make it more difficult for the inner surface of the toilet bowl to become dirty and to make it easier to remove the dirt. In addition, by automatically rotating and spraying the bubbles at regular intervals, it is possible to suppress dirt around the water line in the toilet bowl, particularly, ringing.

In the sanitary washing device according to the present embodiment, when the automatic operation setting is performed to spray the rotating foam after using the toilet, the seat sensor 330 detects when the user stands up from the toilet seat 300, and after about 60 seconds, about 15 seconds. Rotating foam is applied. When the toilet seat 300 is closed, it is detected by the toilet seat opening/closing sensor 331 when a male is not seated on the toilet seat, and after about 60 seconds, the foam is sprayed for about 15 seconds.

Note that after about 60 seconds, the setting can be changed after about 10 seconds, 25 seconds, etc. by the switch of the remote control body 401, and the rotary foaming is started after the user gets up from the toilet seat. It is possible to add or subtract the time until it is turned on to a time that suits the usage of the user. In addition, about 15 seconds of the rotary foam spraying time is configured so that the setting can be changed to 10 seconds, 25 seconds, etc. by the switch of the remote controller body 401, and the amount of foam to be accumulated can be adjusted according to the size of the toilet bowl. You can

Further, in the sanitary washing device of the present embodiment, the fixed foam spray described in FIG. 47 is automatically sprayed not only when the manual splash suppression switch 434 of the remote controller 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, the fixed foam is automatically sprayed, so that splashing during men's small use can be suppressed.

In the sanitary washing device according to the present embodiment, when the automatic operation setting is performed so that the fixed foam is sprayed when the toilet seat is opened, the fixed foam is sprayed for about 15 seconds immediately after the toilet seat 300 is opened when the toilet seat 300 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 body 401, and the amount of foam accumulated can be adjusted according to the size of the toilet bowl. can do.

FIG. 48 shows a configuration for selectively setting the above-mentioned fixed foam spraying or rotary foam spraying automatic operation. Every time the automatic selection setting switch 236 of the operation unit 210 is pressed, a desired setting can be selected. Next to the automatic selection setting switch 236, an after-use automatic rotation spraying lamp 236a, a fixed time automatic rotation spraying lamp 236b, and an automatic fixed foam spraying display lamp 236c when the toilet seat is opened are arranged. Each time the user presses 236, the settings can be changed for three types of automatic operation in the directions indicated by the arrows in FIG.

After use, H0 in which all of the automatic rotation spraying lamp 236a, the automatic rotation spraying lamp 236b at regular time intervals, and the automatic fixed foam spraying display lamp 236c when the toilet seat is open are in the OFF state for all three types of automatic operation Indicates. In this state, when the automatic selection setting switch 236 is pressed once, only the after-use automatic rotation spraying lamp 236a is in the H1 state. 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 set to the “ON” state. In the lamp display of FIG. 48, a circle indicates that the lamp is off and the setting is “off”, and a circle indicates that the lamp is on and the setting is on.

(Embodiment 2)
51 is a perspective view of the sanitary washing device according to the second embodiment. The sanitary washing device according to the second embodiment is a so-called toilet integrated sanitary washing device in which the toilet 110 and the main body 200 are integrally configured. The sanitary washing device according to the first embodiment is a so-called post-installation type sanitary washing device in which the main body 200 is later installed on the toilet separately from the toilet 110.

The sanitary washing device according to the second embodiment also has a configuration for performing the foam spraying operation as in the sanitary washing device according to the first embodiment.

The sanitary washing device according to the second embodiment is different from the sanitary washing device according to the first embodiment in that after the toilet is used, the post-piss flush switch 910 or the post-stool flush switch 920 of the remote controller 400, which is the operation unit, is used. The point is that a flush valve 930 (not shown) that can flush the toilet bowl after urine or flush the toilet bowl after urine is provided.

As in H1, H4, H5, and H7 of FIG. 48, when the automatic operation of foaming shown in FIG. 45 is set after a predetermined time after use, the flush switch operation after urination is performed rather than the flush switch operation after urination. By increasing the amount of bubbles to be sprayed on the inner surface of the toilet bowl at a time, it is possible to make it more difficult for dirt on the toilet bowl after stool that tends to get dirty.

In the case of the sanitary washing device in which the main body 200 is retrofitted to the toilet 110 as in the first embodiment, a signal for flushing the toilet does not enter the control unit 130, and a signal indicating whether the toilet is flushing after urine or flushing. Since the control unit 130 cannot obtain information as well, the amount of automatic foaming after using the toilet cannot be changed according to the size of the toilet.

The sanitary washing device according to the second embodiment has a configuration including the post-piss flush switch 910 and the post-stool flush switch 920 of the remote controller 400 that is the operation unit. The amount of foam can be changed, and the amount of foam applied to the inner surface of the toilet bowl when operating the flush switch after stool is larger than when operating the flush switch after urination, so that the toilet bowl can be easily soiled , Can be made more difficult to attach. As a result, the sanitary washing device can be more accurately sprayed with the detergent without wasting the detergent, and the inner surface of the toilet bowl is less likely to become dirty.

As described above, the sanitary washing device according to the present invention has a rotary foam spraying announcement mode for spraying cleaning foam into the toilet while rotating and driving the direction of the discharge port of the spray nozzle, and the cleaning water passes through the foam generating section. Due to the configuration having the cedar squirrel discharge mode that is discharged from the spray nozzle, when spraying the wash foam from the spray nozzle to the toilet bowl, the spray foam spreads widely in the toilet bowl while the direction of the outlet of the spray nozzle is rotationally driven. As a result, a foam film is formed from the front of the toilet to the inner surface of the rear of the toilet to prevent dirt from adhering to the inner surface of the toilet and the vicinity of the water line, and the flush water is discharged from the spray nozzle through the foam generator. Depending on the warning mode, the foam generation part and the spray nozzle are rinsed with cleaning water, and the detergent is not stuck and clogging the foam generation part and the spray nozzle, so that the foam spray can be stabilized and other spray nozzles are provided. It can also be applied to the usage of equipment.
