Fig. 9 is a perspective view showing the appearance of the sub tank 600 in the first embodiment of the present disclosure; Fig. 10 is a cross-sectional view of the sub tank 600 as viewed in the lateral direction; and Fig. 11 is a front and rear direction of the sub tank 600. A profile view.

As shown in FIG. 9, the sub tank 600 is a tank body 610 formed of a resin material, a water level detecting sensor 620 (FIG. 6) for detecting the water level of the washing water stored in the tank body 610, and detection supply to the tank body. The temperature of the washing water in the 610 is constituted by the inlet water temperature sensor 630 formed by the thermistor of the water temperature detecting unit.

The box body 610 is a front box 611 constituting a front wall, two side walls, a bottom surface, and a top surface of the box, a rear box 612 constituting a rear wall of the box, and three members of an atmosphere opening portion 613 disposed on a top surface of the box body 610. Composition. The overall shape of the box body 610 is formed by a plurality of planes composed of a front wall, a rear wall, two side walls, a bottom surface, and a top surface, and has a substantially quadrangular shape in a plan view. The front wall has an inclined portion that retreats from the lower portion toward the upper portion, and the shape in the side view is formed such that the upper portion is substantially trapezoidal in shape thinner than the lower portion, and the sectional portion of the upper portion of the case body 610 becomes lower than the lower portion. The sectional area is small.

A water inlet 601 is disposed in a lower portion of each of the side walls of the box body 610, and a water outlet 602 is disposed at a lower portion of the wall of the box body 610. The atmosphere opening portion 613 disposed on the top surface of the box body 610 is provided with the communication box body 610. Internal and external atmospheric openings 603. By providing the atmosphere opening 603, the air accumulated in the tank body 610 can be released to the outside, and the internal pressure of the tank body 610 can be maintained at atmospheric pressure at any time.

The inside of the sub tank 600 is maintained at atmospheric pressure at any time, whereby the flow path from the downstream of the sub tank 600 to the water suction port 516d of the water pump 516 as the water discharge amount variable portion can be maintained at atmospheric pressure. Therefore, the water pump 516 as the water discharge amount variable portion can perform the water supply without being affected by the water pressure fluctuation. Therefore, it is possible to exert a stable pump function.

A buffer portion 613a (FIG. 10) having a large cross-sectional area of the flow path is formed on the flow path connected to the atmosphere opening 603 of the atmosphere opening portion 613, and the cleaning water is required to be accompanied by air bubbles from the atmosphere opening port 603. In the case of a sudden outflow or the like, the washing water is temporarily stored in the buffer portion 613a to suppress the function of flowing out from the atmosphere opening port 603.

A partition wall 614 is disposed inside the tank body 610, and the inside of the tank body 610 is divided into two slots of the water tank 615 and the storage tank 616 by the partition wall 614. A water inlet 601 is provided in the vicinity of the bottom surface of the side surface of the water inlet 615, and a water outlet 602 is provided in the vicinity of the bottom surface of the wall after the storage tank 616.

The water inlet 615 and the storage tank 616 are formed by providing the partition wall 614. When the washing water flowing in from the water inlet 601 contains air, the air is released to the outside through the atmosphere opening 603 from the upper portion of the water inlet 615. Therefore, only the air-free washing water can flow in the storage tank 616.

Above the water inlet tank 615, a barrier wall 617 is provided between the upper surface opening portion 615a of the water inlet 615 and the atmosphere opening portion 613, and protrudes from the side wall of the tank body 610 in a substantially horizontal direction (including a horizontal direction). 10). The barrier wall 617 has a size that can cover the entire upper surface opening of the water inlet 615.

Further, inside the water inlet 615, a plurality of rectifying ribs 618 that alternately protrude in a substantially horizontal direction (including a horizontal direction) are formed on the side walls of the tank body 610 and the mutually facing surfaces of the partition wall 614.

The washing water that has flowed in from the water inlet 601 first flows into the lower portion of the water tank 615, and rises in the water inlet 615 while changing the direction in which the flow is reversed by the rectifying rib 618. At this time, when the pressure of the washing water flowing in from the water inlet 601 is high, or when the washing water contains a large amount of air and the flow is significantly disturbed, the flow can be rectified by the rectifying rib 618 appropriately, and The air contained in the washing water is separated by the eddy current generated on the downstream side of the rectifying rib 618.

The washing water that has been separated in the water inlet 615 and separated from the air flows into the storage tank 616 across the upper end of the partition wall 614 to be accumulated.

At this time, even when the pressure of the washing water flowing in from the water inlet 601 is high, or when the washing water contains a large amount of air and the flow is significantly disturbed, the washing water can be blocked by the wall. 617 suppresses the flow upward, and prevents the washing water from directly flowing toward the outside of the sub tank 600 from the atmosphere opening 603 as it directly faces the atmosphere opening portion 613.

As described above, the washing water flowing in from the water inlet 601 separates the air contained in the washing water while rising in the water inlet 615, and releases the separated air from the atmosphere opening port 603 to the outside of the tank body 610. . Thereby, the storage tank 616 can store the washing water not containing air, and is supplied to the heat exchanger 700 from the water outlet 602.

When air is mixed in the washing water supplied from the sub tank 600 to the heat exchanger 700, air bubbles are generated inside the heat exchanger 700, and the temperature inside the heat exchanger 700 rises abnormally, and the heat exchanger 700 is damaged.

By providing the common electrode 621 and the upper limit electrode 623 and the lower limit electrode 624 as the water level electrode 622 on different surfaces, it is possible to obtain an effect of suppressing residual water adhering to the inner surface of the tank body 610 as accumulated water. The case of false detection.

The detection of the water level is performed by applying a DC voltage between the common electrode 621 and the water level electrode 622, and changing the voltage depending on whether the water level electrode 622 is immersed in water. That is, when the washing water flows into the storage tank 616 to raise the water level, so that the lower limit electrode 624 and the upper limit electrode 623 (or only the lower limit electrode 624) are immersed in water, the common electrode 621 and the lower limit electrode 624 and the upper limit electrode 623 are interposed. The voltage is lowered, whereby the control unit 130 can detect the water level.

The upper limit electrode 623 is used for detection of the upper limit water level, and the lower limit electrode 624 is used for detection of the lower limit water level. The upper limit electrode 623 is provided at a position lower than the atmosphere opening port 603, whereby the washing water can be prevented from flowing out of the atmosphere opening port 603. Further, the lower limit electrode 624 is disposed above the water outlet 602, whereby air can be prevented from flowing into the heat exchanger 700. <4> Composition of heat exchanger

In the present embodiment, the energization is stopped after 2 seconds of the upper limit water level detection.

At the time point P2 at which the upper limit water level is detected, basically, the sub tank 600 and the heat exchanger 700 are in a full water state, but by additionally supplying for 2 seconds, the washing water can be more reliably filled with heat exchange. The device 700 and the water pump 516 as the water discharge amount variable portion.

Thereby, since the air can be removed in the heat exchanger 700 and the washing water can be more reliably formed in a full water state, the air-burning of the heat exchanger 700 can be surely prevented, and the safety and durability can be improved. . In addition, by reliably transporting the washing water to the water pump 516 which is the water discharge amount variable portion to form a full water state, the water dispenser of the water pump 516 which is the water discharge amount variable portion can be surely activated.

When the control unit 130 stops the energization of the water stop solenoid valve 514, the control unit 130 starts the driving of the water pump 516 as the water discharge amount variable unit, and activates the fluid regulating valve 517 to start the nozzle unit 820. The buttock washing flow path 835 supplies the washing water.

By driving the water pump 516 as the water discharge amount variable portion, the water level of the sub tank 600 is lowered, and at the time point P4 at which the detection of the upper limit water level by the water level detecting sensor 620 is released, the control unit 130 starts the heat. The drive of the switch 700. By detecting the decrease in the water level, it is possible to confirm that the water pump 516 as the water discharge amount variable portion is normally operated, and to prevent the abnormal temperature rise of the heat exchanger 700 or the like.

The washing water supplied to the buttock washing flow path 835 is ejected from the buttock washing discharge port 834. The sprayed washing water collides with the inner surface of the holding portion 816 provided at the front end of the support portion 810 through the discharge opening 844 and is reflected to clean the outer surface of the nozzle sleeve 840. This cleaning action is called "pre-washing." The pre-washing is performed until the time point P5 after the temperature of the discharged hot water of the heat exchanger 700 reaches 25 ° C and continues for 2 seconds.

When the washing is performed before the end of the time point P5, the control unit 130 starts the driving of the washing nozzle driving unit 860 of the nozzle device 800 so that the nozzle unit 820 moves in and out from the storage position to the buttock washing position. During the movement from the storage position to the buttock washing position, the fluid regulating valve 517 is switched, and the washing water is supplied to the nozzle cleaning flow path 839. The washing water supplied to the nozzle cleaning flow path 839 is ejected from the nozzle cleaning discharge port 838 to the inside of the nozzle cover 840, and the sprayed washing water flows out from the drain port 845 after washing the inner surface of the nozzle sleeve 840. The outside of the nozzle sleeve 840. In this period, since the nozzle unit 820 is heated by the washing water, it is possible to suppress the occurrence of uncomfortable feeling when the cold water is ejected during the subsequent washing of the buttocks.

The control unit 130 switches the fluid regulating valve 517 at the time point P6 at which the nozzle unit 820 has reached the buttock washing position, and starts the supply of the washing water to the buttock washing flow path 835. The washing water supplied to the buttock washing flow path 835 is ejected by the buttock washing discharge port 834, and the user's part is washed by the discharge opening 844. The action of washing the buttocks continues until the time point P11 at which the washing and stopping operation is performed.

In the driving of the heat exchanger 700, the control unit 130 controls the washing water to the set temperature by the detection data of the water inlet temperature sensor 630 and the hot water discharge temperature sensor 730.

By driving the water pump 516 as the water discharge amount variable portion, the water level of the sub tank 600 is lowered, and when the water level detecting sensor 620 detects the lower limit water level, the control unit 130 starts to stop the water. The solenoid valve 514 is energized and continuously energized until the time point P8 at which the water level detecting sensor 620 detects the upper limit water level.

At the time point P8 at which 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 measures the time point P9 until the next water level detecting sensor 620 detects the lower limit water level. The elapsed time. At the time point P9 at which the lower limit water level is detected, the control unit 130 calculates the flow rate by using the measured elapsed time and the amount of water (65 cc) from the upper limit water level to the lower limit water level. At the time point P10 at which the calculation is completed, if there is a difference between the flow rate set for each cleaning intensity and the calculated flow rate, the control unit 130 adjusts the output of the water pump 516 as the water discharge amount variable portion. To correct the flow of washing water.

At the time point P11 at which the operation unit 210 or the remote controller 400 is stopped and stopped, the energization of the water pump 516 and the heat exchanger 700, which are the water discharge amount variable portions, is stopped, and is in the nozzle device 800. The driving of the cleaning nozzle driving unit 860 is started so that the nozzle unit 820 is retracted from the buttock washing position to the storage position.

At the time point P12 at which the nozzle unit 820 has moved back to the storage position, the driving of the washing nozzle driving unit 860 of the nozzle device 800 is stopped, and the water pump 516 and the heat exchanger 700 which are the water discharge amount variable portions are driven again. After the cleaning of the nozzle unit 820 is started, the cleaning is performed, and after the predetermined time elapses, the driving of the water pump 516 and the heat exchanger 700, which is the water discharge amount variable portion, is stopped, and the cleaning is completed.

At the time point P13 after the completion of the nozzle portion 820, the water stop solenoid valve 514 is energized again to supply the washing water to the sub tank 600, and at the time point P14 at which the upper limit water level is detected, the water stop solenoid valve is When the energization of 514 is stopped, the series of control of the buttocks washing is completed, and the sub tank 600 is brought to the upper limit water level, and the washing unit is in the standby state.

FIG. 30 is a timing chart showing a normal use case in the case where the washing operation is performed in the sanitary washing apparatus 100 that is used in the standby state in the first embodiment of the present invention.

The difference from the case of the initial use shown in Fig. 29 is that the sub-tank 600 is already in a full water state at the time point when the washing operation is performed, and the control unit 130 stores the initial use. content.

As shown in FIG. 30, at the time point P20 at which the operation unit 210 or the washing switch of the remote controller 400 (for example, the buttock washing switches 221 and 410) is operated in the standby state in which the sub tank 600 is in the full water state, the control unit 130 will start energizing the water pump 516 to start the supply of the washing water, and start the energization of the heat exchanger 700 at the same time based on the stored data of the control that has been implemented for the initial operation. At the same time, the cleaning operation before the nozzle device 800 is started. Also, the driving of the water level detecting sensor 620 is started at the same time.

The difference from the case of the initial use described above is the control from the time point when the cleaning operation is performed to the time when the energization of the heat exchanger 700 is started, and the control and action after the time P5 of the start of the driving of the nozzle device 800 The action is the same.

As described above, in the sanitary washing apparatus 100 of the present embodiment, the configuration of the washing unit 500 is such that it is not necessary to separately provide a flow rate sensor for detecting the flow rate, but is provided by The water level detecting sensor of the sub tank 600 detects the change of the water level and detects the flow by calculation. Thereby, the configuration of the washing unit 500 can be simplified, and the cost can be reduced.

Further, in the water level detection, by correcting the threshold value of the output voltage change between the electrodes by the temperature, the accuracy of the water level detection and the flow rate detection can be improved, and the conductivity can be made different in a wide range. Water is used as a washing water for a sanitary washing device. Thereby, the range of use and ease of use of the sanitary washing device 100 can be improved.

Moreover, when the sanitary washing apparatus 100 is used initially, the water can be continuously discharged for a predetermined time after the water level of the sub tank 600 is detected, and the water level detecting sensor has been released after the water pump is driven. After the detection of the water level, the energization of the heat exchanger 700 is started to prevent the air heat of the heat exchanger 700 from being burned. Thereby, the safety and reliability can be ensured with a simpler configuration and at a lower cost than the conventional means for preventing air-burning using the flow sensor. <7> Control and action of the discharge of the inner surface of the toilet by the dispensing nozzle

Fig. 31 is a perspective view showing the appearance of the dispensing nozzle 550 in the first embodiment of the present invention; Fig. 32 is a cross-sectional view of the dispensing nozzle 550; and Fig. 33 is a longitudinal sectional view showing the installation state of the dispensing nozzle 550; A front view showing the installation state of the dispensing nozzle 550; and FIG. 35 is a plan view showing the installation position of the dispensing nozzle 550 and the rotation angle of the discharge port of the dispensing nozzle 550. Moreover, FIG. 36 is a timing chart showing the pump output in the rotation angle of the discharge port 550u of the dispersion nozzle 550 in the first embodiment of the present invention.

As shown in FIG. 32, the scattering nozzle 550 rotates the nozzle 550d in the main body 550c including the inlet flow path 550b, and the O-ring 550e and the O-ring 550f axis are rotatably rotated by the dispersion nozzle driving unit 550a as a motor. Sealed composition. Further, the X-ring can be used instead of the O-ring 550f to reduce the torque required for the rotational driving, and the fixing can be easily prevented, and the scattering nozzle driving portion 550a as the motor can be made small and low. The drive part of the torque. The shaft 550n of the distribution nozzle drive unit 550a is fitted into the rotary nozzle 550d.

The washing water or the washing foam supplied from the inlet flow path 550b of the main body 550c passes through a plurality of inlet holes 550h that are cut around the rotary nozzle 550d and is discharged from the discharge port 550u.

As shown in FIGS. 34 and 35, the dispensing nozzle 550 is disposed on the right side of the center of the body 200. In this case, in order to dispose the buttock washing nozzle 831 or the like which is a washing nozzle in the center of the human body in the center, the dispensing nozzle 550 is disposed not on the center but on either side of the left and right sides.

When the user enters the toilet, the control unit 130 of the sanitary washing device 100 disperses the washing foam by detecting that the person enters the room by the human body detecting sensor 450 and rotationally drives the discharge port 550u of the dispensing nozzle 550. The rotary foam dispersion command in the toilet 110 releases the command (foam coating) mode, and enters the action of dispersing the rotary foam in the toilet 110, and starts the operation of the water pump 516 as the water discharge amount variable portion, and opens the switch. Valve 530a.

At this time, since the fluid regulating valve 517 that switches the flow paths of the buttock washing nozzle 831, the female washing nozzle 832, and the nozzle cleaning portion 833 is in a closed state, the washing water from the heat exchanger 700 may be divided. The flow path 530, the check valve 531, and the foam box 532 are discharged from the dispensing nozzle 550 toward the inner surface of the toilet 110.

At this time, the control unit 130 drives the scattering nozzle driving unit 550a of the dispensing nozzle 550 to rotationally drive the direction of the discharge port 550u of the dispensing nozzle 550, and washes the water or washes the foam from the discharge port 550u. A water film or a foam film is formed on the inner surface of the inner surface of 110.

As shown in Fig. 35, the distance from the dispensing nozzle 550 to the inner surface of the toilet 110 is different depending on the direction of the rotation angle of the discharge port 550u of the dispensing nozzle 550. As shown in FIG. 36, the control unit 130 controls the output of the water pump 516 as the water discharge amount variable portion to be changed in accordance with the rotation angle of the discharge port 550u of the discharge nozzle 550.

In the sanitary washing apparatus 100 of the present embodiment, when the direction of the discharge port 550u of the dispensing nozzle 550 is a rotation angle of 160°, the distance to the inner surface of the toilet is the longest, and when the direction of the discharge port 550u is 340°, The distance from the inner surface of the toilet is the shortest.

When the human detecting sensor 450 detects that the user enters the toilet, the control unit 130 causes the pump to act as a water pump 516 of the spouting amount variable portion in response to the rotation angle of the discharge port 550u of the dispensing nozzle 550. The output changes to a time map as shown in FIG.

In other words, when the discharge amount (and the discharge speed) from the discharge port 550u is controlled so that the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet is the farthest (long) rotation angle of 160°, the help is The output of the pump becomes large, and when the distance from the discharge port 550u to the inner surface of the toilet becomes the nearest (short) rotation angle of 340°, the output of the pump is made small.

Therefore, when the front side of the toilet which is the farthest distance from the discharge port 550u of the dispensing nozzle 550 is discharged, the washing water is discharged with the strongest force to feed the washing water to the inner surface of the front side of the toilet. In addition, when the toilet 110 which is the closest distance to the discharge port 550u of the dispensing nozzle 550 is discharged, the washing water is discharged with the weakest force, so that it is possible to spit out the toilet and the like. No, the washing water or the washing foam is delivered to the inner surface of the entire toilet, and the water film or the foam film is formed to the inner surface of the front side of the toilet, and the adhesion of the dirt can be suppressed.

The so-called toilet foam dispersion in which the washing foam is dispersed in the toilet 110 can be performed when the human detecting sensor 450 detects that the user enters the toilet or by operating the operating portion 210 or the dispensing switch 417 of the remote controller 400.

When the toilet foam is dispersed by the signal of the toilet foam, the control unit 130 changes the output of the water discharge amount variable portion 516 as shown in FIG. 36, and causes the dispensing nozzle driving portion 550a to rotate forward. The direction of the discharge port 550u of the dispensing nozzle is driven from the rear of the toilet to the front of the toilet to the rear of the toilet. Thereafter, the control unit 130 reverses the scattering nozzle driving unit 550a, and causes the direction of the discharge port 550u of the dispensing nozzle 550 to pass from the rear of the toilet to the front of the toilet and back to the rear of the toilet, and the foam dispersion is performed by at least one back and forth rotation. step.

Thereby, the output of the spouting amount variable portion can be controlled such that the washing foam reaches the vicinity of the lip 110a of the toilet 110, and the washing foam can be spread over almost the entire circumference of the inner surface of the toilet, and can be from the front of the toilet to the front of the toilet A foam film is formed on the inner surface of the rear to suppress the adhesion of dirt.

In this case, the control unit 130 may be configured to control the output of the water discharge amount variable portion when the nozzle driving unit 550a is rotated forward as shown in FIG. The 550a reverses with a lower output and spits out the wash foam.

By the way, as long as the output of the spouting amount variable portion is increased, the force for discharging the washing foam is enhanced, and is spread by the dispensing nozzle 550 to a distant portion, and as long as the output of the variable amount of the spouting amount is lowered, the spit is washed. The force of the foam is weakened and spread by the dispensing nozzle 550 to a closer location.

Thereby, as shown in FIG. 35, the movement trajectory is distributed by a dotted line. When the direction of the discharge port 550u of the dispensing nozzle is the forward rotation of the back-and-forth rotation drive, the cleaning foam is dispersed on the lip of the toilet 110. Closer to the side of the inner side of the draught. Further, as shown in FIG. 35, the scattering movement trajectory is indicated by a broken line, and when the direction of the discharge opening 550u of the dispensing nozzle is reversed by the one-time rotation driving, the cleaning foam is spread on the side close to the lip of the toilet 110.

Thereby, in the initial stage of dispersing, the upper surface of the discharge port of the toilet 110 can be covered with the washing foam, and the washing foam can be spread on the inner surface of the toilet near the lip, and can be in front of the toilet. The inner surface of the rear forms a foam film and inhibits the adhesion of dirt.

Further, the installation position of the dispensing nozzle 550 is located in front of the main body 200 provided on the toilet 110 as shown in FIGS. 2, 33, 34 and 35. In addition, since the scattering nozzle 550 is provided on the front side of the front end position in the state in which the cleaning nozzle 831 is housed in the nozzle device 800, the direction in which the discharge port 550u of the nozzle is dispersed can be rotationally driven to perform the rear side of the toilet. The foam is dispersed, and a foam film can be formed on the inner surface from the front to the rear of the toilet, and the adhesion of dirt can be suppressed.

In the above description, although it is rotated in the right direction when viewed from above in FIG. 35 and reversed to the leftward direction, it is rotated to the left and reversed to the right. The direction can also be rotated. In short, the direction in which the discharge port 550u of the dispensing nozzle starts to rotate at the time of scattering is referred to as forward rotation, and the direction of return is referred to as reverse rotation.

In addition, in the above description, it is configured to control the output of the water pump 516 as the water discharge amount variable portion to be changed when the rotary foam in which the washing foam is dispersed in the toilet 110 is dispersed. The disclosure is not limited to this. When the rotary foam is dispersed, even if the output of the water pump 516 as the water discharge amount variable portion is not changed, the dispersion nozzle 550 can be configured as described below, and the foam can be formed on the inner surface from the front to the rear of the toilet. Membrane and inhibit dirt adhesion.

As shown in FIG. 33 and FIG. 34, the dispersion nozzle 550 is provided in the main body 200 so that the rotation axis Ax of the discharge port 550u of the scattering nozzle 550 that is rotationally driven is inclined in the front-rear direction and the left-right direction. The inclination of the front-rear direction is such that the lower side of the rotation axis Ax is inclined toward the front side of the toilet 110, and the inclination in the left-right direction is that the lower side of the rotation axis Ax is inclined toward the cleaning nozzle 831 side. With such a configuration, when the distance from the discharge port 550u of the dispensing nozzle 550 to the scattering position is longer and the discharge port 550u is directed toward the front of the toilet 110, the direction of the discharge port 550u is increased, and the washing can be performed. The net foam spreads to the vicinity of the lip in front of the toilet 110. On the other hand, when the distance from the discharge port 550u of the dispensing nozzle 550 to the scattering position is relatively close, and the discharge port 550u faces the rear of the toilet 110, the direction of the discharge port 550u is lowered.

Further, when the distance from the discharge port 550u of the dispensing nozzle 550 to the scattering position is slightly longer, and the discharge port 550u is directed to the left side of the toilet 110, the direction of the discharge port 550u is slightly higher, and the washing foam can be washed. When the distance from the discharge port 550u of the dispensing nozzle 550 to the scattering position is slightly closer to the right side of the toilet 110, the direction of the discharge port 550u is slightly lower. .

When the cleaning foam is dispersed from the dispensing nozzle 550 to the rotating foam of the toilet 110, the nozzle driving portion 550a can be dispersed to drive the direction of the discharge port 550u of the dispensing nozzle 550 around the rotation axis Ax. Although the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet can be changed by the rotation of the dispensing nozzle 550, the washing foam is scattered while changing the height of the discharge port 550u of the dispensing nozzle 550 with the rotation. Therefore, it is possible to form a foam film on the inner surface near the lip from the front of the toilet to the rear side in the form of a scattering trajectory in the form of a dotted arrow in the left direction as shown in FIG. 35, and can be from the front to the rear of the toilet. The surface inhibits the adhesion of dirt.

Further, since the rotating foam is dispersed, the fixed output is not changed by the output of the water pump 516 which is the water discharge amount variable portion, so that the rotating foam in the right direction is scattered in the paired direction in FIG. The same trajectory of the dotted arrow in the left direction is reversed.

By the way, in the present embodiment, as shown in FIG. 33, the rotation axis Ax of the discharge port 550u of the dispensing nozzle 550 has an inclination angle β (an angle with respect to the vertical direction) of 20 degrees in the front-rear direction; The inclination angle γ (the angle with respect to the vertical direction) in the left-right direction is 10 degrees. Further, the height position of the discharge port 550u of the dispensing nozzle 550 is set to be lower than the upper end surface of the toilet 110 at any rotational position.

As described above, the control unit 130 may have a configuration in which the output of the water pump is changed in accordance with the rotation angle of the discharge port 550u of the dispensing nozzle 550, and even if the distance to the front, the side, and the rear of the toilet is different, It is also possible to sprinkle the washing water or the washing foam into a wide range which is delivered to the inner surface of the toilet, and to form a water film or a foam film in a wide range of the inner surface of the toilet to suppress the adhesion of the dirt.

Further, a level change switch capable of adjusting the level (average level) of the output of the water pump described above to be higher or lower may be provided in at least one of the operation unit 210 and the remote controller 400. Thereby, even if the size of the toilet 110 is different, the washing water or the washing foam can be discharged to the inner surface of the entire toilet, and a water film or a foam film can be formed on the inner surface of the front side of the toilet to suppress the dirt adhesion. .

As described above, in addition to causing the control unit 130 to change the output of the water pump in accordance with the rotation angle of the discharge port 550u of the spray nozzle 550, the control unit 130 may be provided so as to spread the rotation angle of the discharge port 550u of the spray nozzle 550. The speed of the nozzle driving portion 550a is changed. By changing the output of the pump (as the water pump 516 of the spouting variable) to change the force of the spit, it can be spread to the inner surface of the farther toilet, and can be suppressed on the inner surface of the toilet. In addition to the scattering, the scattering density can be further averaged by changing the speed of the dispensing nozzle driving portion 550a in accordance with the rotation angle of the discharge port 550u.

That is, when the discharge port 550u of the dispensing nozzle 550 is rotated at a fixed rotational speed, the distance to the inner surface of the toilet is farther, and the scattering density becomes looser, and the distance to the inner surface of the toilet is Farther parts will make the density of the distribution denser.

Although the output of the pump (as the water pump 516 of the spout amount variable portion) is changed, the distribution of the distribution is formed evenly. However, by changing the speed of the dispensing nozzle driving portion 550a in response to the rotation angle, Sparse the inner surface of the toilet more evenly (in other words, without any omission).

For example, when the rotation angle shown in FIG. 35 is used, the washing water or the washing foam which is scattered in front of the toilet 110 is formed in the vicinity of the rotation angle of 160° which is the distance of the discharge port 550u of the discrete cloth nozzle 550. When the discharge density is thinned and the discharge is made thinner in front of the toilet, the scattering density can be increased by making the scattering nozzle 550 the slowest rotation speed. On the other hand, when discharging is performed after the toilet in the vicinity of the rotation angle 340° which is the closest distance to the discharge port 550u of the dispersion cloth nozzle 550, the dispersion nozzle 550 can be diluted by the fastest rotation speed. Dispersion density. In this way, the distribution of the washing water or the washing foam dispersed on the inner surface of the toilet can be more equalized, and the adhesion of the dirt can be suppressed.

In other words, the control unit 130 can change the speed of the dispensing nozzle driving unit 550a in response to the rotation angle of the discharge port 550u of the dispensing nozzle 550, so that the direction from the discharge port 550u of the dispensing nozzle 550 is the distance to the inner surface of the toilet bowl. When the rotation angle in front of the toilet is long, the speed at which the nozzle driving portion 550a is dispersed is set to be small, and when the rotation angle behind the toilet is short to the inner surface of the toilet, the speed of the nozzle driving portion 550a is dispersed. Set to be larger. Thereby, even if the distance to the front, the side, and the rear of the toilet is different, the washing water or the washing foam can be spit out of the inner surface of the toilet without any omission, and can be evenly leaked into the front of the toilet. A water film or a foam film is formed on the surface to prevent the adhesion of dirt.

The control unit 130, when the human detecting sensor 450 detects the entry of a person, spreads the so-called toilet foam which spreads the washing foam from the dispensing nozzle 550 on the inner surface of the toilet, by the dispensing nozzle driving unit 550a. The rotary nozzle 550d is driven at least once and back, and is automatically stopped after the foam is dispersed.

By such an action, when the user enters the toilet room, the foam film can be formed on the inner surface of the toilet before use, and the adhesion of the dirt can be suppressed. In addition, it is not limited to the above-described configuration in which the rotation is repeated from the rotating discharge port 550u, and the number of times of scattering is repeated on the inner surface of the toilet. The user is allowed to select the number of round trips when the toilet foam is dispersed by at least one of the operation unit 210 or the remote controller 400.

Further, when the washing water or the washing foam is spread on the inner surface of the toilet, the dispensing nozzle 550 is configured to rotate the rotary nozzle 550d of the dispensing nozzle 550 back and forth as shown in FIG. With this configuration, the rotation nozzle 550d of the dispersion nozzle 550 is not rotated in the right direction or the left direction, and the direction in which the washing water or the washing foam is dispersed is often the same direction. By rotating it back and forth to form the scattering from the reverse direction caused by the back and forth, and by the scattering from the two directions caused by the forward and reverse rotation, the so-called scattering missing portion is further reduced, and Do it more easily spread. Therefore, it is possible to suppress the adhesion of dirt with a small number of times (time).

In the time chart of Fig. 36, the positive rotation is performed from the rotation angle 0° corresponding to the rear side of the toilet to the rotation angle 340°, and is temporarily stopped, and then, from the rotation angle 340° to the rotation angle 0°. The reverse rotation is performed after the rotation is repeated.

The rotation nozzle 550d of the dispersion nozzle 550 is provided with a rotation restricting portion (not shown) that restricts the rotatable range to a rotation angle of 0 to a rotation angle of 340 by a mechanical stopper.

The rotation restricting portion (not shown) is configured such that a projection formed on a part of the outer circumference of the rotary nozzle 550d rotates together with the rotary nozzle 550d to abut against the rotation regulating wall of the main body 550c, even as a scattering nozzle driving portion. The motor of 550a is intended to rotate the rotary nozzle 550d, and the motor is slipped and idling due to mechanical contact, and the rotary nozzle 550d cannot be rotated.

In this manner, by providing the rotation restricting portion that restricts the rotation range, the configuration in which the scattering nozzle 550 is rotated back and forth in the rotation range that is not restricted by the rotation restricting portion can be performed, and the scattering from the reverse direction caused by the back and forth can be performed by The reversal causes the scattering from the two directions, and the so-called scattered omission portion is further reduced, and the spreading can be more easily performed, so that the dirt adhesion can be suppressed with a small number of times (time).

In addition, since the dispensing nozzle driving unit 550a is configured by the motor, the dispensing nozzle driving unit 550a can recognize the origin of the rotational position at the position where the rotation restricting portion has abutted, thereby improving the accuracy of the rotation angle and the rotational speed. And it can form a dispersion with little dispersion unevenness.

Further, as described in the configuration of the water circuit of Fig. 6, the divergent flow path 530 which is divided between the water pump 516 as the water discharge amount variable portion and the fluid regulating valve 517 in the washing water supply flow path 690 The switch valve 530a and the check valve 531 are connected to supply the washing water to the foam tank 532, and the spray nozzle 550 is connected downstream of the foam tank 532. Further, a detergent tank 533 and a detergent pump 534 for supplying the lotion are connected to the foam tank 532, and an air pump 535 for supplying air to the foam tank 532 to manufacture the washing foam is provided.

By opening the on-off valve 530a by the control unit 130, the washing water from the heat exchanger 700 can be sent by the water pump 516 as the water discharge amount variable portion, and the washing water or the washing foam can be discharged from the dispensing nozzle 550. At this time, the discharge amount of the washing water or the washing foam discharged from the dispensing nozzle 550 can be increased or decreased in response to the increase or decrease in the output of the water pump (the pump) 516 and the air pump 535 as the variable amount of the water spouting amount. And the force of the spit (spit speed and discharge pressure).

In addition, the switching passage 530a is provided in the branch flow path 530, and the flow path switching valve may be provided in the branching portion of the branch flow path 530 and the washing water supply flow path 690.

The user can select a configuration in which at least one of the operation unit 210 and the remote controller 400 of the main body 200 indicates that the washing water is to be distributed by the dispensing nozzle 550 or the washing foam is dispersed.

This is a foam tank 532 which supplies a washing agent between the switching valve 530a and the dispensing nozzle 550 to generate a washing foam, and discharges the washing foam from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet. Thereby, the inner surface of the toilet is formed not only by the water film formed by the dispersion of water or warm water, but also by the foam film caused by the washing foam containing the lotion, thereby further enhancing the suppression. The effect of dirt adhesion.

Further, by the foam film caused by the washing foam containing the lotion, the suppression of the unpleasant odor and the comfort of the visually clean impression can be improved.

In the sanitary washing apparatus 100 of the present embodiment, the washing water or the washing foam is dispersed from the dispensing nozzle 550 on the inner surface of the toilet, and may be borrowed when the human detecting sensor 450 detects that a person has entered. Dispersion is performed by the operation switch 210 or the spread switch 417 of the remote controller 400.

Thereby, when it is feared that there is dirt, the toilet 110 can be cleaned at any time by forming a foam film composed of a washing foam containing a lotion.

Further, in order to disperse the washing water or the washing foam on the inner surface of the toilet by the dispensing nozzle 550, the user may previously use a spreading switch (not shown) of at least one of the operating portion 210 or the remote controller 400. Choose arbitrarily.

Further, the control unit 130 has a washing command issuing mode in which a selection instruction can be made by at least one of the operation buttons of the operation unit 210 and the remote controller 400. In the washing command issuing mode, the control unit 130 is configured to open the opening and closing valve 530a while stopping the detergent pump 534 that supplies the lotion from the detergent tank 533 of the foam generating unit 560 to the foam tank 532. The washing water variable portion 516 conveys the washing water to the foam tank 532 and discharges it from the dispensing nozzle 550.

Thereby, the path from the foam tank 532 to the dispensing nozzle 550 can be flushed with washing water to prevent clogging of the path and the dispensing nozzle 550 due to the fixing of the lotion, and the dispensing nozzle 550 is fixed by the lotion. The resulting rotation is poor. Also, the flushing of the inner surface of the toilet can be performed.

That is, since the lottery pump 534 is in the stopped state during the flushing operation, the washing tank 532 is supplied with the washing water without supplying the lotion. Therefore, the path from the foam tank 532 to the dispensing nozzle 550 can be flushed by the washing water, and the inner surface of the toilet can also be flushed by the washing water.

Further, although flushing water without temperature control may be used for flushing during the flushing operation, the temperature of the washing water sent from the heat exchanger 700 may be controlled to about 40 ° C to obtain more. Superior rinsing effect.

In order to set the washing command release mode, the user can operate the washing switch 223 of the operating unit 210 to perform flushing at an arbitrary timing.

Further, in the vicinity of the flushing switch 223 for the operation unit 210 provided in the above-described washing command issuing mode, the washing lamp 223a (FIG. 4) such as an LED is provided, and the control unit 130 is set to be performed in the previous time. After the washing, for example, when the predetermined time is 20 days, the washing lamp 223a can be automatically blinked to prevent forgetting to rinse.

When the cleaning foam is scattered on the inner surface of the toilet by the dispensing nozzle 550, the control unit 130 may be configured to respond to the above-described pump output of FIG. 36 in response to the rotation angle of the discharge port 550u of the dispensing nozzle 550. Similarly, the output of the air pump 535 is changed. Thereby, even if the distance to the front side, the side, and the back of the toilet is different, the washing foam can be discharged to the entire inner surface of the toilet, and a foam film can be formed on the inner surface of the front side of the toilet to suppress the adhesion of dirt.

That is, when the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet is the farthest (long) rotation angle of 160°, the output of the air pump 535 is set to be large, thereby making it possible to make the output of the air pump 535 large. The air pressure of the air pump 535 becomes higher, and the force of the washing foam from the discharge port 550u to the far side is enhanced. On the other hand, when the distance from the discharge port 550u to the inner surface of the toilet is near the nearest (short) rotation angle of 340°, the output of the air pump 535 is set to be small, whereby the air pump 535 can be made. The air pressure becomes lower, and the weakening force that causes the washing foam to fly out is weakened. In this way, the washing foam can be spit out of the inner surface of the toilet without any omission.

Further, the present invention further includes a dirt detecting unit (not shown) that detects the dirt of the toilet 110 by an image element or the like, and the control unit 130 can be further improved by moving back and forth in a portion where the dirt remains. Scale inhibition effect. Further, in addition to the method of partially returning to and from the dirt portion, the dirt portion may be set such that the rotation speed of the discharge port 550u of the dispersion nozzle 550 is rotated at a low speed or the pump output is increased. <8> Control and action of discharge by the dispensing nozzle in the open seat and non-sitting state

Hereinafter, in the case where the male urinates, the dispensing switch of the operation unit 210 or the remote controller 400 is operated in a state where the user is not seated in the toilet seat 300 and the toilet seat 300 is almost vertically opened.

At this time, since the user is in the standing posture and the toilet seat 300 is in the open state, the signal of the seat opening detection unit 331 is the toilet seat open state, and the signal of the seat detection unit 330 is the non-seat state.

When the dispensing switch 417 is pressed by the user, as shown in FIG. 37, the control unit 130 rotationally drives the dispensing nozzle driving unit 550a until the direction of the discharge port 550u of the dispensing nozzle 550 is the position toward the discharge port 115 of the toilet (in this case). In the embodiment, as shown in the graph of FIG. 37, the discharge port 550u has a rotation angle of 20° or so, and the discharge nozzle drive unit 550a is stopped. Thereafter, the water discharge amount variable portion 516 is controlled at a medium-level output, and the washing foam is discharged to the discharge port 115 of the toilet for a predetermined time (in the present embodiment, 8 seconds) as indicated by an arrow in FIG. The washed foam which has been discharged will be in a state of covering the upper surface of the drain port 115 of the toilet 110 (that is, the upper portion of the so-called toilet bowl 110).

With respect to the rotary foam spread command release (foam coating) mode of the control unit 130 described in the above item <7>, the direction of the discharge port 550u of the spray nozzle 550 is rotationally driven, and the wash foam is dispersed. In the <8> item, the fixed foam distribution command release (splash suppression) mode of the control unit 130 is maintained in a state in which the discharge port 550u of the dispensing nozzle 550 is kept fixed. The wash foam is dispersed into the fixed foam dispersion in the toilet 110.

As described above, it is conceivable that, in the case of a male urinating, the operation unit 210 or the remote controller 400 is operated in a state where the user is not seated in the toilet seat 300 and the toilet seat 300 is almost vertically opened. A manual splash suppression switch 434 as a spread switch. At this time, as shown in FIG. 37, the control unit 130 rotationally drives the dispensing nozzle driving unit 550a until the direction of the discharge port 550u of the dispensing nozzle 550 is toward the rear of the toilet (in the present embodiment, the graph is as shown in FIG. 37). The scattering nozzle drive unit 550a is stopped until the rotation angle of the outlet 550u is around 20°. Thereafter, the water discharge amount variable portion 516 is controlled by a high output, and the washing foam is discharged toward the rear of the toilet for a predetermined time (in the present embodiment, 8 seconds) as shown by an arrow in FIG.

At this time, the discharge port 550u of the dispersion nozzle 550 is opened in the direction of the angle α degrees with respect to the rotation axis of the dispersion nozzle 550: Ax as shown in the cross-sectional view of FIG. 33, and therefore the discharge port is directed to FIG. Direction: The direction in which Ac(b) stops is fixed and the washing foam is discharged.

In this manner, since the jetting amount variable portion 516 is controlled by the high output after the rotation is driven so that the discharge port 550u of the dispensing nozzle 550 faces the rear of the toilet, the washing foam can be quickly formed to cover the row in the toilet with the foam. The water level on the upper portion of the outlet 115 and the upper portion of the water line in the toilet. Therefore, it is possible to suppress the odor and the adhesion of dirt near the draft surface of the toilet by washing the foam. Moreover, when the urine is dropped to the vicinity of the water surface in the toilet, the cushioning effect of the foam covering the water surface can be suppressed, and the rebound to the surroundings can be suppressed. That is, by performing foam dispersion in a direction in which the dispensing nozzle 550 has been fixed, the foam is scattered rapidly, and foam is formed on the upper surface of the water in the toilet 110, and the bouncing scattering prevention of urine can be achieved.

Furthermore, in the present embodiment, when the user urinates, when the user operates the manual splash suppression switch 434 of the remote controller 400, the control unit 130 becomes a fixed foam dispersion command release (splash suppression) mode, and rotationally drives the spread nozzle drive. In the portion 550a, the direction of the discharge port 550u of the dispensing nozzle 550 is the position toward the discharge port 115 of the toilet, and the dispensing nozzle driving portion 550a is stopped. In addition, although the water discharge amount variable portion 516 is controlled by the high output, and the washing foam is discharged toward the toilet, the position where the washing foam is fixedly dispersed may be the vicinity of the discharge port 115. Any of the front side, the center, and the rear side of the toilet.

That is, by rapidly forming a state in which the upper surface of the water surface and the toilet waterline are covered with foam in a short time after the start of the discharge of the washing foam, the bouncing of the urine can be suppressed, and the draught in the toilet 110 can be suppressed. The dirt near the line and its upper part is attached.

Further, the cleaning foam is dispersed in the fixed foam dispersion of the toilet 110 in a state where the direction of the discharge port 550u of the dispensing nozzle 550 is fixed by the fixed foam spreading command release (splash suppression) mode, in FIG. In order to control the water discharge amount variable portion 516 with a high output, the washing foam is discharged toward the discharge port 115 of the toilet 110. However, similarly to the rotational foam dispersion described in the above item <7>, the output of the water pump 516 as the water discharge amount variable portion may be a fixed output that does not change, that is, when the fixed foam is dispersed. The output of the water pump 516, which is the water discharge amount variable portion, is set to the same state as the output when the rotating foam is dispersed.

As described above, the sanitary washing device of the present embodiment includes the main body 200 provided in the toilet 110, the washing nozzle 831 for washing the human body, the foam generating portion 560 for generating the washing foam, and the washing water or washing on the inner surface of the toilet. The discharge nozzle 550 of the clean foam, the water discharge amount variable portion (water pump 516) that can change the flow rate of the washing water sent to the discharge nozzle, and the spray nozzle drive unit 550a that rotates the discharge outlet 550u of the spray nozzle . Further, an on-off valve 530a that opens and closes the water path to the dispensing nozzle 550, a control unit 130 that controls these operations, and an operation unit 210 (or a remote controller 400) that instructs the control unit 130 to be set are provided.

Further, the control unit 130 has a rotary foam spread command release (foam coating) mode, rotationally drives the discharge nozzle 550 in the direction of the discharge port 550u, and spreads the wash foam in the toilet 110; and fixes the foam spread command to be issued ( In the splash suppression mode, the cleaning foam is dispersed in the toilet in a state where the direction of the discharge port 550u of the dispensing nozzle 550 is kept constant.

With such a configuration, when the toilet foam is dispersed in the toilet 110 by the dispensing nozzle 550, the washing foam can be dispersed into the toilet while rotating the direction of the discharge port 550u of the dispensing nozzle 550. The ground is delivered, and a foam film can be formed on the inner surface from the front to the back of the toilet, and the dirt adhering to the inner surface of the toilet and the water line can be suppressed. Further, by the fixed foam spread command issuing mode in which the washing foam is dispersed in the toilet in a state where the discharge port 550u of the dispensing nozzle 550 is kept fixed, the washing foam can be quickly formed on the upper surface of the water in the toilet 110. The water surface of the upper portion of the discharge port 115 in the toilet 110 is covered with the washing foam. Thereby, it is possible to suppress the odor which is unpleasant when urinating and the scattering caused by the splash of the male urination by washing the foam.

Furthermore, as a result of the verification experiment on the scattering suppression effect caused by the splash of the male urination, it can be confirmed that, as shown in Fig. 49, the thickness of the foam as the foam height is about 5 mm, as compared with The condition without foam has an effect of improving, and when the thickness of the foam is about 10 mm, the suppression effect becomes remarkable. That is, it is preferable that the thickness of the foam on the water surface in the toilet 110 caused by the foam dispersion has a lower limit of 5 mm or more and an upper limit of 50 mm or less. Further, 50 mm or less is the upper limit of the foam height for preventing the accumulated foam from sticking to the buttocks when the user is seated on the toilet seat.

In the sanitary washing apparatus 100 of the present embodiment, the dispensing nozzle 550 is provided on the main body 200 so that the rotation axis Ax of the discharge port 550u of the scattering nozzle 550 that is rotationally driven is inclined in the front-rear direction and the left-right direction. Further, the inclination in the front-rear direction is a configuration in which the lower side of the rotation axis Ax is inclined toward the front side of the toilet 110, and the inclination in the left-right direction is a configuration in which the lower side of the rotation axis Ax is inclined toward the cleaning nozzle 831 side.

Thereby, when the toilet foam is dispersed from the dispensing nozzle 550 to the toilet 110, the distance from the discharge port 550u of the dispensing nozzle 550 to the scattering position becomes farther, and the discharge port 550u faces the front of the toilet. In this case, the direction of the discharge port 550u is increased, and when the distance from the discharge port 550u of the dispensing nozzle to the scattering position is closer, the discharge port 550u is directed toward the rear of the toilet, and the direction of the discharge port 550u is lowered. .

In this manner, the washing foam can be dispersed while changing the height of the discharge port 550u of the dispensing nozzle with the distance from the discharge port 550u of the dispensing nozzle to the inner surface of the toilet 110, and even if the rotating foam is dispersed, the amount of water discharged can be prevented. The output of the water pump 516 of the variable portion is changed, and a foam film may be formed on the inner surface from the front to the rear of the toilet to suppress the adhesion of dirt.

Further, in the sanitary washing apparatus 100 of the present embodiment, when the toilet 110 is rotated and foamed from the dispensing nozzle 550, the control unit 130 causes the dispensing nozzle driving unit 550a to rotate forward so that the discharge nozzle 550 is discharged. The direction of the 550u passes behind the toilet and passes behind the toilet to the rear of the toilet. Next, the control unit 130 reverses the scattering nozzle driving unit 550a so that the direction of the discharge nozzle 550u of the dispensing nozzle is returned from the rear of the toilet to the rear of the toilet through the front of the toilet, and the rotating foam dispersion is performed by at least one back and forth rotation. The steps.

Thereby, when the rotating foam is dispersed from the dispensing nozzle 550 and the rotating foam is dispersed in the toilet 110, the dispensing nozzle driving unit 550a is rotated forward by the control unit 130 so that the direction of the discharge nozzle 550u of the dispensing nozzle is behind the toilet. Pass the front of the toilet and reach the back of the toilet. Thereafter, the control unit 130 reverses the scattering nozzle driving unit 550a so that the direction of the discharge port 550u of the dispensing nozzle 550 passes through the front of the toilet and returns to the rear of the toilet, and is rotated at least once. Further, the output of the spouting amount variable portion is controlled such that the washing foam reaches the vicinity of the lip of the toilet 110. Thereby, the washing foam can be spread over almost the entire circumference of the inner surface of the toilet, and a foam film can be formed on the inner surface from the front to the rear of the toilet to suppress the adhesion of dirt.

Further, the sanitary washing device 100 of the present embodiment further includes a human body detecting sensor 450 for detecting entry and exit of the user into the toilet room, and the control unit 130 is configured to detect that the user goes to the toilet room at the human body detecting sensor 450. Upon entering, the rotating foam is dispersed in the toilet 110 by at least one of the aforementioned back and forth rotations.

Thereby, when the human body detecting sensor 450 detects that the user enters into the toilet room, the rotation of the discharge nozzle 550u of the dispensing nozzle can be performed at least once and the rotation of the washing foam is dispersed on the inner surface of the toilet 110. The foam is dispersed, and a foam film can be formed on the inner surface of the toilet before use to suppress the adhesion of the dirt.

Moreover, the sanitary washing apparatus 100 of the present embodiment is provided with a foam tank 532 that transports washing water by the water discharge amount variable portion 516 by opening the opening and closing valve 530a by the control unit 130, and washes the washing tank 533. The lotion pump 534 supplied to the foam tank 532 and the air pump 535 which supplies air to the foam tank. Further, it is a configuration in which the washing water or the washing foam of the foam box 532 is discharged from the dispensing nozzle 550.

According to this configuration, not only water or warm water can be discharged from the surface of the washing nozzle 831 or the inner surface of the toilet, but also the washing foam containing the lotion can be discharged. Thereby, the effect of washing and the effect of suppressing adhesion of dirt can be improved. Further, the unpleasant odor can be suppressed by the washing foam containing the lotion, and the comfort of visual cleansing can be improved.

Further, in the sanitary washing apparatus 100 of the present embodiment, the control unit 130 has a washing command issuing mode, and the washing command issuing mode is a configuration in which the washing tank 533 that supplies the foam tank 532 to the foam generating portion 560 is provided. In a state where the lotion pump 534 of the lotion is stopped, the on-off valve 530a is opened, and the washing water is transferred to the foam tank 532 by the spouting amount variable portion 516, and is discharged by the dispersing nozzle 550.

With such a configuration, the path from the foam tank 532 to the dispensing nozzle 550 is flushed by the washing water, and clogging due to the fixing of the washing agent in the path and the dispensing nozzle 550 can be prevented, and the dispensing nozzle 550 can be prevented. Poor rotation caused by the fixation of the lotion. Also, the flushing of the inner surface of the toilet can be performed.

In the present embodiment, the motor is used as the scattering nozzle driving unit 550a. However, it may be configured as another driving source, for example, by discharging the foam from the discharge port 550u of the dispensing nozzle 550. The scattering nozzle 550 is rotated.

Further, a dispensing nozzle 550 in which the washing foam is dispersed in the vicinity of the lip of the toilet 110, and a dispensing nozzle 550 in which the washing foam is dispersed in the vicinity of the discharge port 115 of the toilet 110 may be provided. The plurality of dispensing nozzles 550 can be independently rotated to rotate or interlocked to cause them to be rotated.

Further, the dispensing nozzle 550 may be provided with a discharge port 550u that disperses the washing foam near the lip of the toilet 110, and a discharge port 550u that disperses the washing foam near the discharge port 115 of the toilet 110.

In the present embodiment, the dispensing nozzle 550 is configured to be scattered in the vicinity of the lip of the toilet 110 and in the vicinity of the discharge port 115 of the toilet 110. However, the dispensing nozzle 550 may be formed in the vicinity of the lip of the toilet 110. Outside the vicinity of the discharge port 115 of the toilet 110, it is spread at other locations.

Further, as shown in FIG. 34, FIG. 38, and FIG. 39, in the sanitary washing apparatus 100 of the present embodiment, the cuff cover 250 is integrally provided so as to protrude forward of the side portion of the main body 200. Further, the sleeve cover 217 and the lotion level confirmation window 216 are provided, and the sleeve cover 217 is provided in front of the operation unit 210 disposed above the cuff cover 250, and the lotion level is set. The confirmation window 216 is a detergent tank 533 which is inside the sleeve cover 217 and has a foam generating portion 560 which is a transparent or translucent container at the foremost portion of the sleeve cover 250, and can be in front of the sleeve cover 250. The liquid level of the lotion of the lotion tank 533 is confirmed.

According to this configuration, since the user can easily visually confirm the remaining amount of the lotion before going to the sanitary washing device 100, the lotion can be replenished before the lotion is used up.

Thus, the detergent tank 533 having the lotion injection port 537 provided with the detergent tank cap 536 on the upper side is disposed at the foremost portion in front of the operation portion 210 of the sleeve casing 250, and is located in front of the toilet bowl. The most recent position makes it possible to form a composition that is easy to supplement with the lotion. Further, by providing the detergent tank 533 having the lotion injection port 537 at the foremost portion forward of the operation portion 210 of the sleeve cover 250, the sleeve cover 217 can be opened further than the operation portion 210 and When the lotion injection port 537 replenishes the lotion to the detergent box 533, the case where the lotion is sprinkled on the operation portion 210 is prevented.

Further, as shown in FIG. 38 and FIG. 39, since the height position of the lotion injection port 537 is lower than the operation unit 210, when the lotion is replenished to the detergent tank 533, it is possible to prevent further prevention. The detergent is sprinkled on the operation unit 210.

Further, in the sanitary washing device 100 of the present embodiment, the lotion pump hose 561 shown in Figs. 6 and 38 is configured to conduct the lotion from the outlet side of the lotion pump 534 to the foam tank 532. The inside of the inlet side is a hollow cylindrical tube, and is formed by a so-called double tube which is covered with a pipe member on the outer side of the pipe member. Further, the inner diameter of the lotion pump hose 561 is thinner than the inner diameter of the foam box hose 562 that conducts the cleaning foam from the foam tank 532 to the dispensing nozzle 550.

With such a configuration, even if the pressure from the cleaning pump 534 is high, the lotion pump hose 561 can be prevented from being greatly expanded and broken, and the washing foam can be stably spread from the dispensing nozzle 550. .

Further, in the sanitary washing device 100 of the present embodiment, the lottery pump hose 561 having a double tube structure is formed by coating the outer side of the elastomer resin tube with a heat shrinkable tube. The double tube is constructed, but the material is not limited to these. Even with other materials, it is possible to prevent expansion and breakage by forming a double tube, and it is possible to stably spread the cleaned foam from the dispensing nozzle 550.

Further, as is apparent from FIGS. 2, 39, and 40, the sanitary washing apparatus 100 of the present embodiment is provided with a main body 200 including a control unit 130, a dispensing nozzle 550, and a nozzle device 800, and the like. 202 is configured to cover the front surface of the rear body cover 201.

Moreover, the dispensing nozzle 550 is disposed in front of the rear body casing 201, and the front and upper portions of the spreading nozzle 550 are covered by the body casing 202, and the discharge port 516e of the lower portion of the spreading nozzle 550 is opened to the inner surface of the toilet. The form is set (Figure 40).

In the first embodiment of the present invention, FIG. 40 is a cross-sectional view showing a center portion of the dispensing nozzle 550 provided in the rear body casing 201, which is cut in the front-rear direction.

The washing foam discharged from the discharge port 516e of the dispensing nozzle 550 is usually discharged toward the inner surface of the toilet as indicated by the dotted line T in Fig. 40. However, when the washing is performed by the washing command issuing mode described above, when the washing water without foam is discharged from the discharge port 516e from the dispensing nozzle 550 without containing the lotion, there will be as shown in FIG. The two-point chain line S shows the possibility that the jet stream is diffused and scattered, and scattered outside the toilet to wet the floor.

On the other hand, in the sanitary washing apparatus 100 of the present embodiment, as shown in FIG. 40, a scattering guard portion 550z is formed in the main body casing 202, and the scattering shielding portion 550z passes the discharge port 516e from the dispensing nozzle 550. The upward jet that exceeds the upper limit is blocked by the wall and falls into the toilet 110. By the scattering prevention portion 550z, it is possible to prevent the washing foam discharged from the dispensing nozzle 550 and the washing water from being discharged outside the toilet 110, and it can be dispersed in the toilet 110.

That is, a portion of the body casing 202 of the body 200 before and after covering the spreading nozzle 550 has an upward jet that exceeds the upper limit of the discharge port 550u from the dispensing nozzle 550, and is dropped into the toilet. The scattering protection portion 550z can prevent the washing foam discharged from the dispensing nozzle 550 and the washing water from being discharged outside the toilet 110.

Further, the scattering guard portion 550z formed in the main body casing 202 can prevent not only the washing foam discharged from the dispensing nozzle 550 but also the washing water from being discharged outside the toilet 110. The sanitary washing device 100 is configured to attach and detach the body 200 to the toilet 110 through the main body fixing plate 240 (FIG. 43). When the builder or the user initially sets up the toilet 110 and the user removes the body 200 from the toilet 110 and wants to clean the dirt near the lower portion of the body 200, there is a sanitary washing that has been removed. The body 200 of the net device 100 is temporarily placed on a pedestal or a floor or the like.

Thus, even when the body 200 of the sanitary washing device is temporarily placed on the pedestal or on the floor, the discharge port 516e of the dispensing nozzle 550 located lower than the mounting surface of the body 200 can be scattered. The guard 550z is protected from contact with the pedestal or the floor, and the damage of the dispensing nozzle 550 can be prevented. FIG. 41, which is a front view of the body 200, shows the surface of the pedestal when the body 200 is placed, which is the two-point chain line of FIG. 42 of the side view of the body 200. As shown in FIGS. 41 and 42, the discharge preventing portion 550z causes the discharge port 516e of the dispensing nozzle 550 not to come into contact with the surface of the pedestal.

In the sanitary washing apparatus 100 of the present embodiment, the scattering guard 550z is formed in the main body casing 202. However, the scattering guard 550z may be formed in the main body 550c of the dispensing nozzle 550 or the like. .

Fig. 43 is a perspective view of the main body fixing plate 240 and the main body casing 201 after the main body 200 in the first embodiment of the present disclosure.

Further, for the sake of convenience of explanation, the perspective view of the rear body casing 201 is omitted, and the control unit 130, the scattering nozzle 550, the nozzle device 800, and the like which are disposed inside are omitted.

The main body fixing plate 240 is fixed to the toilet 110 by inserting a mounting bolt (not shown) through the position adjusting long hole 241. Further, the main body fixing plate 240 is aligned with the center of the main body 200, and the rear portion of the main body fixing plate 240 is slightly floated, and when the main body 200 is slid from the toilet surface until the sound of "clicking" is made and pushed in, The body 200 is fixed to the toilet 110 by a ratchet mechanism.

Further, when the main body 200 is detached from the toilet 110, the main body loading/unloading button 242 located beside the main body 200 is pushed deep into the body by a finger, and the main body 200 is pulled out toward the front to be detached.

Further, as shown in Fig. 43, a magnet 243 is embedded in the resin body fixing plate 240, and the rear body casing 201 is mounted to detect whether the body 200 has been attached to the toilet 110 or whether the body has been The loading and unloading sensor 244 is removed from the toilet 110.

The loading and unloading sensor 244 is constituted by a reed switch, and as shown in a partial cross-sectional view of FIG. 44, the state in which the body 200 has been mounted to the toilet 110 can be achieved by the magnet 243 of the main body fixing plate 240. The loading and unloading sensor 244 of the rear body casing 201 is detected in a facing positional relationship. Further, when the main body 200 is detached from the toilet 110, the magnet 243 is separated from the detachment sensor 244, and the detachment sensor 244 detects the detached state.

The control unit 130 is configured not to perform the discharge operation by the dispensing nozzle 550 when the main body 200 is detached from the toilet 110 by the attaching and detaching sensor 244. Thereby, when the main body 200 is detached from the toilet 110, even if a button such as the manual foam application switch 433 of the remote controller main body 401 or the manual splash suppression switch 434 is instructed to discharge the discharge by the dispensing nozzle 550, the scatter is performed. The discharge operation by the nozzle 550 is also not performed. Therefore, it is possible to prevent an unfavorable condition such as accidentally spraying the washed foam toward the floor and the person.

Further, the control unit 130 is configured not to prohibit the discharge by the buttock washing nozzle 831 and the genital washing nozzle 832 even when the main body 200 is detached from the toilet 110 by the attaching and detaching sensor 244. Running. Therefore, in the event that the loading and unloading sensor 244 malfunctions and the erroneous recognition is made that the body 200 has been detached from the toilet 110, the basic function of the sanitary washing device 100 can be performed and for the user. It is important to wash your hips and wash your genitals.

Fig. 45 is a timing chart showing the state in which the rotary foam is dispersed in the sanitary washing device 100 according to the first embodiment of the present invention.

When the manual foam application switch 433 of the remote controller main body 401 is pressed, the detergent pump 534 is reversed for 2 seconds at the time point N2 shown in FIG. 45, and the forward rotation starts at the time point of N3. The water pump 516 and the air pump 535 are operated to supply the foam tank 532 with lotion, water, and air to generate a washing foam. The generated washing foam is spread from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet 110. By dispersing the rotating foam on the inner surface of the toilet bowl, it is possible to make the dirt difficult to adhere to the inner surface of the toilet, and it is easy to remove the dirt.

At this time, the discharge port 550u of the dispensing nozzle 550 can be rotationally driven by the scattering nozzle driving portion 550a as a stepping motor. In the time chart of FIG. 45, in the time chart of FIG. 45, the foam is dispersed while rotating from the stop position at the time point of N3 to the limit position at the time point of N6, and the time point from N6 is obtained. When the limit position starts to the stop position at the time point of N9, the foam is scattered and returned. Then, at the time point of N11, the operation of the water pump 516 and the air pump 535 is automatically stopped, and the rotation of the foam is automatically ended.

Further, between N3 and N11 for performing the rotary foam dispersion, the control unit 130 continuously operates the water pump 516 and the air pump 535. On the other hand, the lottery pump 534 performs intermittent operation in such a manner as to stop after the forward rotation from N3 to N4, stop after the forward rotation from N6 to N7, and stop after the forward rotation from N9 to N10.

According to the experiment, the lotion pump 534 is continuously operated in the rotation foam dispersion, and the intermittent operation mode can make the mixing of the lotion, water, and air more desirable, and can generate a more stable washing foam. As such, the lotion pump 534 can be intermittently operated by rotating the foam spread to produce a stable wash foam. Moreover, the unnecessary use of the lotion can be prevented, and the labor of the lotion replenishment can be reduced.

Further, in the sanitary washing apparatus 100 of the present embodiment, the lotion pump 534 is set to operate for 2 seconds in a 6 second cycle under intermittent operation.

Further, in the timing chart when the rotational foam dispersion shown in Fig. 45 is performed, although the graph of the heat exchanger 700 is depicted by a broken line, it is shown that the water pump 516 is used when the rotary foam is dispersed. When the water supplied to the foam tank 532 is a temperature lower than 20 ° C, the heat exchanger 700 is heated so that the water temperature becomes about 20 ° C and is supplied to the foam tank 532. When the water temperature is low, the foaming property is lowered, but by supplying the heat exchanger 700 so that the water temperature becomes about 20 °C, a preferable washing foam can be produced in the foam tank 532.

Further, in the time chart when the rotary foam dispersion shown in Fig. 45 is performed, the detergent pump 534 is reversed in N2 to N3 before the time point N3 at which the rotation of the foam is started. This is because: the tube pump is used in the lotion pump 534, and the lotion on the outlet side of the tube is reversed on the part where the tube has been crushed by the roller. The liquid is countercurrently flowed to return the crushed portion to a cylindrical shape and then forwarded, whereby a stable amount of the lotion can be delivered.

Further, in the time chart when the rotational foam dispersion shown in Fig. 45 is performed, the scattering nozzle driving portion 550a is driven from the stop position to the abutment from the time point N11 to the time point N14 at which the rotational foam dispersion ends. At the position, the rotation detecting micro switch is pressed, and the origin position of the dispensing nozzle driving unit 550a as the stepping motor is recognized, and then the control unit 130 drives and controls to return to the stop position.

As described above, by the origin return operation of the discharge nozzle driving unit 550a, even if the stepping motor that spreads the nozzle driving unit 550a generates a slip phenomenon due to an increase in some rotational load or the like, the driving step cannot be performed. The rotation of the number of rotations causes an offset in the amount of rotation, and the driving position at which the rotation position of the rotating foam is reset as the starting position can be accurately corrected. That is, the rotating foam spread can be performed at a stable position all the time.

In addition, the rotation detecting micro switch that is pressed by the origin return operation of the nozzle driving unit 550a can detect that the lotion is fixed around the discharge port 550u of the dispensing nozzle 550 for some reason. It is not possible to perform rotational driving even when the rotation detecting micro switch is pressed. That is, when the rotation of the rotating foam is performed, when the signal for pressing the rotation detecting micro switch is not obtained, the washing lamp 223a which should be urged to perform the washing operation by the washing switch 223 can be made to be notified. .

In the sanitary washing apparatus 100 of the present embodiment, the time from the N3 time point from the start of the rotational foam dispersion to the N12 time point at which the rotary foam dispersion is completed is set to about 15 seconds. This approximately 15 seconds can be matched with the size of the toilet 110, and is changed to about 10 seconds, about 25 seconds, and the like according to the amount of accumulated foam.

With respect to the set rotation foam dispersing time, when the time until the rotation detecting micro switch is pressed is delayed by about 10% or more, the washing lamp 223a is brightly flashed "flashing" and "flashing" once. The light is displayed to urge the washing switch 223 to indicate the washing operation. The washing operation is such that the washing water which has been heated to about 40 ° C by the heat exchanger 700 flows out and is washed for about 3 minutes. By this washing operation, the foam generating portion 560, the dispensing nozzle 550, and the like can be rinsed with the washing water to prevent the washing agent from adhering and clogging the foam generating portion 560 and the dispensing nozzle 550, and the like, and stable foam dispersion can be performed.

When the dispensing nozzle 550 is hardened by the lotion or the like, and the operation is deteriorated, and the rotation time of the rotating foam is set to be about 20% or more until the time of pressing the rotation detecting micro switch is delayed, the washing is performed. The lamp 223a is turned on and off in a flashing manner by "flashing, flashing", "flashing, and flashing", and pressing the washing switch 223 to perform the washing operation, and washing the discharge port 550u of the dispensing nozzle 550 with a toothbrush or the like. nearby.

Moreover, in the time chart when the rotating foam dispersion shown in FIG. 45 is performed, the flow path switching diagram displays the following operation: at the time point of N2 to N3, the water circuit of FIG. 6 is used as the water supply. The supply destination of the washing water in the pumping water amount variable portion 516 is switched from the nozzle device 800 side to the bubble generating portion 560 side, and is switched from the bubble generating portion 560 side to the nozzle device 800 at the time point of N11 to N13. side.

That is, at the time point of N2 to N3, the control unit 130 closes the fluid regulating valve 517 and opens the switching valve 530a, and at the time of N11 to N13, the opening and closing valve 530a is closed and the fluid regulating valve 517 is opened. In addition, in place of the on-off valve 530a, the flow path switching valve may be disposed at a branch portion 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. .

FIG. 46 is a timing chart of the washing operation in the sanitary washing apparatus 100 according to the first embodiment of the present disclosure.

When the washing switch 223 of the operation unit 210 is pressed and the control unit 130 is in the washing command issuing mode, the supply destination of the washing water is switched from the nozzle device 800 side to the bubble generating portion 560 at the time point of N2 to N3. side. Then, in about 2 minutes from the time point of N3~N8, the lotion pump 534 will remain in the stopped state as it is, to heat the heat exchanger 700 to a washing water of about 40 ° C, as a water pump. The jetting amount variable portion 516 is sent to the foam tank 532 and discharged from the dispensing nozzle 550.

Further, in about one minute from the time point of N8 to N10, in addition to the washing water which has been heated to about 40 ° C, the air is sent to the air pump 535 of the foam box 532 while being washed and washed.

Thus, in the washing operation of the rinse washing, only the washing water is first supplied, and the air pump 535 is operated from the middle to apply air and perform flushing. Thereby, most of the lotion components remaining in the foam tank 532 and the flow path can be quickly and efficiently discharged from the dispensing nozzle 550 by the washing water, and then the force of the air bubbles caused by the air pump 535 is also When added, a small amount of residual amount which acts as a lotion component is also washed away, so that effective rinsing can be performed in a short time.

When the flushing is completed for 3 minutes from the time point of N3 to N10, the standby operation is performed in N10 to N14 so that the detergent pump 534 is reversed and rotated so that the rotating foam dispersion and the fixed foam dispersion can be normally performed. The washing operation is automatically completed.

Fig. 47 is a timing chart showing the state in which the foam is dispersed in the sanitary washing device 100 according to the first embodiment of the present invention.

When the manual splash suppression switch 434 of the remote controller main body 401 is pressed, at the time point of N2 shown in FIG. 47, the detergent pump 534 is reversed for 2 seconds, and the forward rotation starts at the time point of N3, and the water is operated. The pump 516 and the air pump 535 supply the lotion, water, and air to the foam tank 532 and generate a wash foam.

The resulting cleaned foam is spread from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet 110. The foam can be accumulated on the surface of the toilet 110 by dispersing the fixed foam on the inner surface of the toilet to suppress splashing of the male urination.

The time chart for performing the fixed foam dispersion shown in Fig. 47 differs from the time chart for the rotational foam dispersion described in the previous Fig. 45 in that it is the same as when the rotating foam is dispersed. The direction in which the discharge port 550u is rotationally driven by the distribution of the nozzle driving portion 550a is such that the dispensing nozzle driving portion 550a does not rotate the direction in which the discharge port 550u is driven, but the fixed foam dispersion is maintained in a fixed state. . The time chart of Fig. 47 is the same as the time chart of Fig. 45, and the description overlapping with Fig. 45 is omitted.

Further, the origin position, the stop position, and the limit position in FIGS. 45 to 47 are, for example, in FIG. 37, the origin position is 0 degrees (backward), and the stop position is 20 degrees (shun). The position of the hour hand direction, and the position of the limit position is 340 degrees (clockwise direction). However, the present disclosure is not limited to this, and may be, for example, a position where the origin position is 5 degrees (clockwise from the front side), and the stop position is 60 degrees (clockwise from the rear side). And the limit position is 300 degrees (clockwise) position.

When the fixed foam of FIG. 47 is dispersed, when the command to fix the foam dispersion is issued, the dispensing nozzle driving portion 550a stops the direction of the discharge port 550u as it is at a stop position of about 60 degrees from the rear to the clockwise direction. Immediately fix the foam spread. In this case, the discharge nozzle drive unit 550a is driven such that the direction of the discharge port 550u is in a state of waiting at a position of about 60 degrees as the stop position in advance, and after the fixed foam is instructed to be dispersed, it can be dispersed. When the nozzle 550 does not move, the washing foam is immediately discharged to the inner surface of the toilet to rapidly form the foam height required for splash suppression in the water surface of the toilet before the male urination starts.

In particular, by setting the direction of the discharge port 550u in the stop position to be, the wash foam facing the slope of the inner surface of the toilet and hitting the slope can be flowed down the water surface to rotate 50 to 70 on the inner slope of the toilet. At a position of about 60 degrees, it is possible to form a clean foam on the entire surface of the water very quickly.

Further, in the sanitary washing apparatus 100 of the present embodiment, the rotary foam dispersion described in FIG. 45 can be set not only when the manual foam application switch 433 of the remote controller main body 401 is pressed, but also after the toilet (that is, the toilet) Rotating foam dispersion is automatically performed after use. In addition, it is also possible to set the rotation of the rotating foam automatically every fixed period of time. Rotating foam dispersion is automatically performed after the toilet is used, or at regular intervals, so that the dirt is more difficult to adhere to the inner surface of the toilet and the dirt is more easily removed.

Further, by rotating the foam in an automatic manner at regular intervals, it is possible to suppress dirt, particularly annular stains, in the vicinity of the water line in the toilet 110.

In the sanitary washing apparatus 100 of the present embodiment, when the automatic operation of the rotary foam dispersion after the use of the toilet is set to be in progress, when the user stands up from the toilet seat 300, the seat sensor 330 detects the result, and After 60 seconds, a rotating foam spread of about 15 seconds was performed. When the toilet seat 300 is closed when the person is not seated in the toilet seat, the seat sensor 331 is detected, and after about 60 seconds, the rotary foam spread is performed for about 15 seconds.

Further, the above-described about 60 seconds can be changed by setting the switch of the remote controller main body 401 to about 10 seconds or 25 seconds later. Thereby, the time from when the user stands up from the toilet seat to when the rotary foam is started can be increased or decreased to a time that matches the user's usage mode.

Further, the rotation foam spread time is about 15 seconds, and the configuration can be changed to 10 seconds, 25 seconds, or the like by the switch of the remote controller main body 401. Thereby, the amount of the accumulated foam can be increased or decreased in accordance with the size of the toilet 110.

Further, in the sanitary washing apparatus 100 of the present embodiment, the fixed foam dispersion described in FIG. 47 can be set not only when the manual splash suppression switch 434 of the remote controller main body 401 is pressed, but also when the toilet seat 300 is opened. Fixed foam dispersion. By setting the toilet seat 300 to be opened when the male urinates, the fixed foam dispersion is automatically performed, and the splash of the male urination can be suppressed.

In the sanitary washing apparatus 100 of the present embodiment, when the automatic operation of fixing the foam dispersion when the toilet seat 300 is opened is set to be in progress, when the toilet seat 300 is opened, the fixed foam is performed for about 15 seconds immediately after the toilet seat 300 is opened. spread.

Further, the fixed foam dispersion time of about 15 seconds is set to be changed to 10 seconds or 25 seconds by the switch of the remote controller main body 401. Thereby, the amount of the accumulated foam can be increased or decreased in accordance with the size of the toilet 110.

Fig. 48 is a view showing the configuration of the automatic operation for selectively setting the fixed foam dispersion and the rotating foam dispersion in the first embodiment of the present invention.

The favorite setting can be selected each time the setting switch 236 is automatically selected by the operation unit 210. The automatic selection setting switch 236 is disposed besides: automatically rotating the scatter lamp 236a after use, automatically rotating the scatter lamp 236b every fixed period of time, and automatically fixing the foam scatter display lamp 236c when the toilet seat is opened, and pressing the operation portion 210 each time When the setting switch 236 is automatically selected, the setting can be changed for three types of automatic operation in the direction indicated by the arrow in Fig. 48.

After the use, the scatter lamp 236a is automatically rotated, the scatter lamp 236b is automatically rotated every fixed period of time, and the H0 is automatically turned off when the toilet seat is opened. The H0 is all of the three types of automatic operation. The state of "". When the automatic selection setting switch 236 is pressed once in this state, it becomes an H1 state in which the automatic rotation scatter lamp 236a is turned on only after use.

In this way, it is possible to form a state in which the setting is shifted to H2, H3, ... H6 every time the automatic selection setting switch 236 is pressed, and the automatic operation of the three types of H7 is "open". Further, in the lamp number display of Fig. 48, the ○ symbol indicates a state in which the lamp is turned off and is "off", and the symbol is a state in which the lamp is turned on and is "on".

For example, in FIG. 48, in the case of H2, H4, H6, and H7 which are set for the automatic operation of the rotating foam dispersion at a fixed time, the rotating foam shown in the time chart of FIG. 45 can be dispersed. It is automatically executed every about 3 hours to suppress dirt, especially annular stains, near the waterline in the toilet 110.

Furthermore, the above-mentioned about three hours can be changed by setting the switch of the remote controller main body 401 to every 6 hours, every 12 hours, or every 24 hours, and the like. It is convenient to increase or decrease the convenience of the user such as the number of automatic operations when the long period is not present. (Second embodiment)

Fig. 51 is a perspective view of the sanitary washing apparatus 1000 according to the second embodiment of the present invention.

The sanitary washing device 1000 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 formed.

The sanitary washing device 100 according to the first embodiment is a so-called additional sanitary washing device that is placed on the toilet 110 after the toilet 110 is a separate body 200.

In the sanitary washing apparatus 1000 of the second embodiment, similarly to the sanitary washing apparatus 100 of the first embodiment, a configuration in which the foam dispersing operation is performed is provided.

The sanitary washing device 1000 according to the second embodiment differs from the sanitary washing device 100 of the first embodiment in that it has a flush valve (not shown) which is used after the toilet is used. As the urinal flush switch 910 of the remote control 400 of the operation unit or the post-transpiration flush switch 920, the toilet flush after urination or the toilet flush after urination can be performed.

In the case where H1, H4, H5, and H7 shown in FIG. 48 are set to have the automatic operation of the foam dispersion shown in FIG. 45 after a predetermined time after use, the post-flush switch 920 can be set. The amount of foam spread on the inner surface of the toilet during operation is more than the amount of foam spread during the operation of the urinal flush switch 910, so that the toilet dirt after the stool which is easily dirty is more difficult to adhere.

In the first embodiment, when the main body 200 is added to the sanitary washing device 100 of the toilet 110, if the signal of the flushing toilet 110 fails to enter the control unit 130, the control unit 130 may not be able to obtain a flush after urination or The signal information of the flush after the stool. Therefore, it is impossible to change the amount of automatic foam dispersion after the toilet is used, depending on the size of the toilet.

The sanitary washing device 1000 according to the second embodiment includes a urinal flush switch 910 and a post-transpiration flush switch 920 in the remote controller 400 as an operation unit, so that the control unit 130 is caused based on the signal. It is possible to change the amount of automatic foam dispersion after the toilet is used. Further, the control unit 130 is configured to set the amount of foam spread on the inner surface of the toilet when the toilet flush switch is operated to be larger than that during the operation of the urinal flush switch. Thereby, it is possible to make the toilet dirt after the stool which is easy to be dirty more difficult to adhere. According to this method, it is possible to carry out the foam dispersing more appropriately in accordance with the use occasion without wasting the lotion, and it is possible to realize the sanitary washing apparatus 1000 in which the dirt is hard to adhere to the inner surface of the toilet 110. Industrial availability

As described above, according to the present disclosure, it is possible to provide a sanitary washing device which forms a foam film on the inner surface from the front to the rear of the toilet to suppress the adhesion of dirt. Therefore, the present disclosure is also applicable to a sanitary washing device that cleans a part of a human body, and a device including another device that spreads the nozzle, and is also useful.
