<3> Configuration of Sub-tank FIG. 9 is a perspective view showing the appearance of the sub-tank, FIG. 10 is a cross-sectional view in the lateral direction of the sub-tank, and FIG. 11 is a cross-sectional view in the front-rear direction of the sub-tank. .

  As shown in FIG. 9, the sub-tank 600 is supplied into a tank body 610 that is molded from a resin material, a water level detection sensor 620 that detects the level of cleaning water stored in the tank body 610, and the tank body 610. It is comprised with the incoming water temperature sensor 630 which consists of thermistors which are the water temperature detection means which detects the temperature of wash water.

  The tank body 610 includes a front tank 611 that constitutes the front wall, both side walls, the bottom surface, and the top surface of the tank, a rear tank 612 that constitutes the rear wall of the tank, and an air release portion disposed on the top surface of the tank body 610. 613 and three members. The overall shape of the tank body 610 is formed by a plurality of planes including a front wall, a rear wall, both side walls, a bottom surface, and a top surface, and the shape in plan view is a substantially square shape. The front wall has an inclined part that retreats from the middle, the side view shape is formed in a substantially trapezoidal shape in which the upper part is thinner than the lower part, and the cross-sectional area of the upper part of the tank body 610 is smaller than the lower part. .

  A water inlet 601 is provided at the lower part of one side wall of the tank main body 610, and a water outlet 602 is provided at the lower rear wall of the tank main body 610. The tank main body 610 is disposed on the top surface of the tank main body 610. An air opening 603 that communicates the inside and the outside of 610 is provided. By providing the air opening 603, the air accumulated in the tank main body 610 can be released to the outside, and the internal pressure of the tank main body 610 can be constantly maintained at atmospheric pressure.

  Since the inside of the sub tank 600 is always maintained at atmospheric pressure, the flow path from the downstream of the sub tank 600 to the water inlet 516d of the water pump 516, which is the water discharge amount variable means, is also maintained at atmospheric pressure. Since the water pump 516 can supply water without being affected by fluctuations in water pressure, a stable pump function can be exhibited.

  A buffer part 613a having a large cross-sectional area of the flow path is formed in the flow path communicating with the open air opening 603 of the open air part 613, so that the washing water is likely to flow out from the open air opening 603 with bubbles.

  The wash water flowing in from the water inlet 601 first flows into the lower part of the water inlet tank 615 and rises in the water inlet tank 615 while changing the flow direction at 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 flow is significantly disturbed including a large amount of air, the flow is appropriately rectified by the rectifying rib 618 and the flow of the rectifying rib 618 is increased. Air contained in the wash water is separated by vortices generated on the downstream side.

  The wash water from which the air rising in the water tank 615 is separated passes over the upper end of the partition wall 614 and flows into the storage tank 616 to be stored.

  At this time, even if the pressure of the cleaning water flowing in from the water inlet 601 is high or the flow is significantly disturbed including a large amount of air, the upward flow of the cleaning water is suppressed by the barrier 617, and the cleaning water Directly hitting the atmosphere opening portion 613 and preventing the sub tank 600 from flowing out from the atmosphere opening port 603 is prevented.

As described above, the wash water flowing in from the water inlet 601 is separated from the air contained in the wash water while rising in the water inlet tank 615, and the separated air is released from the atmosphere opening 603 to the outside of the tank body 610. The Wash water that does not contain air is stored in the storage tank 616 and supplied to the heat exchanger 700 from the water outlet 602.

  When air is mixed in the cleaning water supplied from the sub tank 600 to the heat exchanger 700, bubbles are generated in the heat exchanger 700, and the temperature inside the heat exchanger 700 is abnormally increased, and heat exchange is performed. The apparatus 700 may be damaged, and by providing the partition wall 614 to prevent air from entering, the effect of preventing the heat exchanger 700 from being damaged can be obtained.

Can be obtained.

  The water level is detected by applying a DC voltage between the common electrode 621 and the water level electrode 622 and changing the voltage depending on whether or not the water level electrode 622 is submerged. That is, when the wash water flows into the storage tank 616 and the water level rises and the lower limit electrode 624 and the upper limit electrode 623 are submerged, the voltage between the common electrode 621, the lower limit electrode 624 and the upper limit electrode 623 decreases, thereby causing the control unit 130. Detects the water level.

  The upper limit electrode 623 is used for detecting the upper limit water level, and the lower limit electrode 624 is used for detecting the lower limit water level. The upper limit electrode 623 is installed at a position lower than the atmosphere opening port 603, thereby preventing washing water from flowing out from the atmosphere opening port 603. In addition, the lower limit electrode 624 is installed above the water outlet 602, so that air can be prevented from flowing into the heat exchanger 700.

  The control unit 130 starts driving the water pump 516 that is the water discharge amount varying means at the time P3 when the energization of the water stop electromagnetic valve 514 is stopped, and operates the flow control valve 517 to clean the bottom of the nozzle unit 820. Supply of washing water to the channel 835 is started.

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

  The cleaning water supplied to the buttocks cleaning channel 835 is ejected from the buttocks cleaning jet outlet 834. The jetted cleaning water passes through the jet opening 844 and is reflected on the inner surface of the holding portion 816 provided at the tip of the support portion 810 to clean the outer surface of the nozzle cover 840. This cleaning operation is called pre-cleaning. The pre-cleaning is continued until time point P5, which is 2 seconds after the hot water temperature of the heat exchanger 700 reaches 25 ° C.

When the pre-cleaning is completed at time P5, the control unit 130 starts driving the cleaning nozzle driving unit 860 of the nozzle device 800, and moves the nozzle unit 820 from the storage position to the buttocks cleaning position. During the movement from the storage position to the buttocks cleaning position, the flow control valve 517 is switched to supply cleaning water to the nozzle cleaning flow path 839. The cleaning water supplied to the nozzle cleaning flow path 839 is jetted into the nozzle cover 840 from the nozzle cleaning jet port 838, and the jetted cleaning water cleans the inner surface of the nozzle cover 840 and then the drain port 845 to the outside of the nozzle cover 840. To leak. In the meantime, the nozzle part 820 is warmed by the washing water, and it is possible to suppress the feeling of discomfort due to the cold water being ejected during the hip cleaning performed later.

  At time P6 when the nozzle unit 820 reaches the buttocks cleaning position, the control unit 130 switches the flow control valve 517 and starts supplying cleaning water to the buttocks cleaning channel 835. The cleaning water supplied to the buttocks cleaning flow path 835 is ejected from the buttocks cleaning outlet 834 and passes through the ejection opening 844 to clean the user's local area. The buttocks cleaning operation is continued until a time point P11 at which the cleaning stop operation is performed.

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

  By continuing to drive the water pump 516 that is the water discharge amount varying means, the water level of the sub tank 600 is lowered, and the control unit 130 energizes the water stop solenoid valve 514 at the time P7 when the water level detection sensor 620 detects the lower limit water level. And the energization is continued until time point P8 when the water level detection sensor 620 detects the upper limit water level.

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

  At the time point P11 when the operation unit 210 or the remote controller 400 is operated to stop cleaning, energization of the water pump 516, which is the water discharge amount variable means, and the heat exchanger 700 is stopped, and the nozzle device 800 is connected to the cleaning nozzle drive unit. The driving of 860 is started, and the nozzle unit 820 moves backward from the buttocks cleaning position to the storage position.

  At the time point P12 when the nozzle unit 820 is retracted to the storage position, the driving of the cleaning nozzle driving unit 860 of the nozzle device 800 is stopped, and the water pump 516 and the heat exchanger 700, which are water discharge amount variable means, are driven again, and the nozzle unit 820 is driven again. Cleaning is started after the cleaning, and at a time P13 when a predetermined time has elapsed, the driving of the water pump 516 and the heat exchanger 700 as the water discharge amount variable means is stopped, and the post-cleaning ends.

  The water stop solenoid valve 514 is energized again at the time P13 when the post-cleaning of the nozzle portion 820 is completed, the wash water is supplied to the sub tank 600, and the power supply to the water stop solenoid valve 514 is stopped at the time P14 when the upper limit water level is detected. Then, a series of control of the buttocks cleaning is completed, and the cleaning means is in a standby state with the sub tank 600 at the upper limit water level.

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

  The difference from the case of the initial use shown in FIG. 29 is that the sub tank 600 is already full at the time point P20 when the cleaning operation is performed, and that the control unit 130 stores that the initial use has been performed. is there.

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

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

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

  Moreover, by correcting the threshold value for determining the output voltage change between the electrodes in the water level detection by the temperature, the accuracy of the water level detection and the flow rate detection can be improved, and water with different conductivity can be removed over a wide range. By being able to be used as cleaning water, it is possible to improve the usage range and usability of the sanitary cleaning device.

  In addition, during initial use of the sanitary washing device, water flow continues for a predetermined time after detection of the sub tank full condition, and after the water pump is driven, the heat exchanger starts energizing after the detection of the upper limit water level is eliminated. Therefore, it is possible to prevent the heat exchanger from being blown, and it is simpler and less expensive than the commonly used means of preventing air blow using a flow sensor, and it is safe and reliable. Can be secured.

<7> Control and action of discharge to inner surface of toilet bowl by spray nozzle FIG. 31 is a perspective view showing the appearance of the spray nozzle, FIG. 32 is a sectional view of the spray nozzle, and FIG. 33 is a sanitary washing device FIG. 34 is a front view showing the installation state of the spray nozzle in the sanitary washing device, and FIG. 35 is the installation position of the spray nozzle and the rotation angle of the discharge port of the spray nozzle in the sanitary washing device. FIG. FIG. 36 is a chart showing the pump output at the rotation angle of the discharge port of the spray nozzle.

  As shown in FIG. 32, the spray nozzle 550 includes a rotary nozzle 550d that is rotatably supported by an O-ring 550e and an O-ring 550f in a body 550c having an inlet channel 550b by a spray nozzle driving unit 550a that is a motor. It is a sealed configuration. By using an X ring instead of the O-ring 550f, the torque required for rotational driving can be reduced and sticking can be easily prevented, and the spray nozzle driving unit 550a, which is a motor, can be made small and low torque. it can. The shaft 550n of the spray nozzle driving unit 550a is fitted to the rotary nozzle 550d.

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

  As shown in FIGS. 34 and 35, the spray nozzle 550 is installed on the right side from the center of the main body 200. This is because priority is given to placing the buttocks washing nozzle 831 and the like, which are washing nozzles for washing the human body part, in the center, and therefore the spray nozzle 550 is arranged not on the center but on the left or right side thereof. It is.

When the user enters the toilet, the control unit 130 of the sanitary washing device 100 detects the person entering the room with the human body detection sensor 450, and rotates the direction of the discharge port 550u of the spray nozzle 550 to rotate the washing bubbles in the toilet bowl. Rotating foam spraying command (foam coat) mode is applied, and the operation moves to the operation of spraying the rotating foam on the toilet. The operation of the water pump 516 as the water discharge amount variable means is started, and the on-off valve 530a is opened.

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

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

  As shown in FIG. 35, the distance from the spray nozzle 550 to the inner surface of the toilet varies depending on the rotation angle direction of the discharge port 550u of the spray nozzle 550. As shown in FIG. 36, the control unit 130 performs control so as to change the output of the water pump 516 serving as the water discharge amount varying means in accordance with the rotation angle of the discharge port 550u of the spray nozzle 550.

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

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

  Therefore, when the water is discharged to the front of the toilet having the farthest distance from the discharge port 550u of the spray nozzle 550, the wash water is discharged with the strongest force and reaches the inner surface of the front of the toilet, and the discharge port 550u of the spray nozzle 550. When the water is discharged to the rear of the toilet, which is the closest distance from the toilet, the cleaning water is discharged with the weakest momentum. It can discharge so that it may reach, and a water film or a foam film can be formed to the inner surface ahead of a toilet bowl, and adhesion of dirt can be controlled.

  When the human body detection sensor 450 detects that the user has entered the toilet, or by operating the spraying switch 417 of the operation unit 210 or the remote controller 400, so-called toilet bowl spraying for spraying cleaning foam on the toilet bowl. Can do. As shown in FIG. 36 described above, the control unit 130 rotates the spray nozzle driving unit 550a in the normal direction while changing the output of the water discharge amount varying unit 516, when the toilet foam is sprayed by the toilet foam spraying signal. The direction of the discharge port 550u of the spray nozzle reaches from the rear of the toilet bowl to the rear of the toilet bowl, and reverses the spray nozzle driving unit 550a so that the direction of the spray nozzle discharge port 550u passes from the rear of the toilet bowl to the rear of the toilet bowl. There is a step of spraying bubbles by returning at least one reciprocating rotation.

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

  In this case, as shown in FIG. 36, the control unit 130 performs cleaning by controlling the output of the water discharge amount variable means during the normal rotation of the spray nozzle driving unit 550a at a lower output than the reverse rotation of the spray nozzle driving unit 550a. It is good also as a structure which discharges a bubble. By the way, if the output of the water discharge amount variable means is increased, the momentum at which the cleaning bubbles are discharged becomes stronger and sprayed to a location far from the spray nozzle, and if the output of the water discharge amount variable means is lowered, the momentum at which the cleaning bubbles are discharged becomes weaker. It is sprayed in the place near the spray nozzle. As a result, during the forward rotation in which the direction of the discharge port 550u of the spray nozzle is driven to reciprocate as shown by the dotted movement trajectory shown by the dotted line in FIG. 35, washing bubbles are formed on the side closer to the draft surface inside the rim of the toilet bowl. Be sprayed. Then, at the time of reverse rotation in which the direction of the discharge port 550u of the spray nozzle is driven by one reciprocating rotation as shown by the broken movement trajectory shown by the broken line in FIG. 35, the cleaning foam is sprayed on the side near the rim of the toilet bowl.

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

  In addition, the installation position of the spray nozzle 550 is located in front of the main body 200 which is placed on the toilet 110 and fixedly installed as shown in FIG. 2, FIG. 33, FIG. 34, FIG. The spray nozzle 550 is installed on the front side of the front tip position where the nozzle device 800 for cleaning the human body by protruding the cleaning nozzle 831 from the storage position to the buttocks cleaning or bidet cleaning position is stored. The direction of the discharge port 550u of the nozzle can be rotationally driven to disperse bubbles from the back of the toilet, and a foam film can be formed from the front of the toilet to the back inner surface to suppress the adhesion of dirt.

  In the above description, the forward rotation is shown as rotating clockwise when viewed from above in FIG. 35, and the reverse rotation is rotating counterclockwise. However, the forward rotation is clockwise rotation and the counterclockwise rotation is normal rotation. It may be clockwise. In short, the direction in which the discharge port 550u of the spray nozzle starts to rotate during spraying is referred to as normal rotation, and the return direction is referred to as reverse rotation.

  In the above description, the control is made so that the output of the water pump 516, which is the water discharge amount variable means, is changed when the rotating foam is sprayed into the toilet bowl. Even without changing the output of the water pump 516, which is a means for changing the amount of water, by forming the spray nozzle 550 into the configuration described below, a foam film is formed from the front of the toilet to the rear inner surface to suppress the adhesion of dirt. Can do.

  As shown in FIGS. 33 and 34, the spray nozzle 550 is installed in the main body 200 with the rotation axis Ax of the discharge port of the spray nozzle driven to rotate being inclined in the front-rear direction and the left-right direction. The inclination of the rotation axis Ax is inclined to the front side of the toilet 110, and the inclination in the left-right direction is inclined from the discharge port 550u of the spray nozzle 550 to the spray position by the configuration where the rotation axis Ax is tilted to the cleaning nozzle 831 side. When the discharge port 550u is directed in front of the toilet 110 where the distance is longer, the direction of the discharge port 550u is higher, so that cleaning bubbles can be sprayed to the vicinity of the rim in front of the toilet 110, and sprayed from the discharge port 550u of the spray nozzle 550. When the discharge port 550u faces the rear of the toilet 110 where the distance to the position is short, the direction of the discharge port 550u is lowered. In addition, when the discharge port 550u is directed to the right side of the toilet 110 where the distance from the discharge port 550u of the spray nozzle 550 to the spray position is slightly far, the direction of the discharge port 550u is slightly higher, and the rim on the right side of the toilet 110 is close to the rim. When the discharge port 550u is directed to the left side of the toilet 110 where the cleaning bubble can be sprayed and the distance from the discharge port 550u of the spray nozzle 550 to the spray position is slightly close, the direction of the discharge port 550u is slightly lowered.

Thus, at the time of rotating foam spraying in which the cleaning foam is sprayed from the spray nozzle to the toilet bowl, the direction of the discharge port 550u of the spray nozzle is rotationally driven around the rotation axis Ax by the spray nozzle driving unit 550a. As the spray nozzle is rotated, the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl is changed. However, the cleaning foam is sprayed while the height of the discharge port 550u of the spray nozzle 550 is changed with the rotation. , A foam film can be formed from the front of the toilet to the inner surface close to the rear rim with a scattering trajectory as depicted by the counterclockwise broken arrow in FIG. 35, and the adhesion of dirt from the front of the toilet to the rear inner surface can be suppressed. Can do. Since the output of the water pump 516, which is the water discharge amount variable means, is a constant output that does not change when spraying the rotating foam, the same trajectory as the counterclockwise dashed arrow in FIG. Scattered to follow.

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

  As described above, the controller 130 changes the output of the pump in accordance with the rotation angle of the discharge port 550u of the spray nozzle 550, so that even if the distance to the front, side, and rear of the toilet is different, The cleaning foam can be discharged so as to reach a wide area on the inner surface of the toilet bowl, and a water film or a foam film can be formed on a wide area of the inner surface of the toilet bowl to suppress adhesion of dirt.

  It should be noted that the operation unit 210 or the remote controller 400 may be provided with a level change switch that can adjust the pump output level (average level) to be higher or lower. As a result, even if the size of the toilet bowl is different, it is possible to discharge the washing water or washing bubbles so that they reach the entire inner surface of the toilet bowl. Can do.

  In addition to the control unit 130 changing the output of the pump according to the rotation angle of the discharge port 550u of the spray nozzle 550, the control unit 130 drives the spray nozzle according to the rotation angle of the discharge port 550u of the spray nozzle 550. You may make it change the speed of the part 550a. By changing the output of the pump (water pump 516, which is a means for changing the amount of water discharged), the momentum of the discharge can be changed so that it can reach the inner surface of a distant toilet, and scattering on the inner surface of a close toilet can be suppressed. By changing the speed of the spray nozzle driving unit 550a according to the rotation angle of the outlet 550u, the spray density can be made more uniform.

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

  For example, in the case of the rotation angle shown in FIG. 35, the cleaning water or the cleaning foam sprayed in front of the toilet having a rotation angle that is the farthest distance from the discharge port of the spray nozzle is about 160 °, and the spray density is dispersed. When the spray nozzle is discharged forward, the spray nozzle has the slowest rotation speed, the spray density is increased, and the rotation angle at the closest distance from the discharge nozzle outlet is around 340 °. When sprayed backward, the spray nozzle 550 has the fastest rotation speed and the spray density is thinned, so that the distribution of the wash water or the wash foam sprayed on the inner surface of the toilet can be made more uniform, and the adhesion of dirt is suppressed. I can.

That is, the control unit 130 changes the speed of the spray nozzle driving unit 550a according to the rotation angle of the discharge port 550u of the spray nozzle 550, so that the direction of the discharge port 550u of the spray nozzle 550 has a long distance to the inner surface of the toilet bowl. When the rotation angle of the spray nozzle drive unit 550a is low when the rotation angle is in front of the toilet bowl and the distance to the toilet bowl is short, the speed of the spray nozzle drive unit is increased when the rotation angle is behind the toilet bowl. On the other hand, even if the distance to the rear is different, the washing water or washing foam can be uniformly discharged to the inner surface of the toilet bowl, and the water film or foam film is formed evenly to the inner surface of the toilet bowl to adhere dirt. Can be suppressed.

  The control unit 130 detects a person entering the room by the human body detection sensor 450, and then the spray nozzle 550 sprays cleaning foam on the inner surface of the toilet bowl, so-called toilet bowl spraying, the spray nozzle driving unit 550a causes the rotary nozzle 550d to reciprocate at least once. It is automatically stopped by spraying bubbles while being driven to rotate. Thereby, when a user enters the toilet room, a foam film can be formed on the inner surface of the toilet before use, and adhesion of dirt can be suppressed. In addition, what is necessary is just a structure which sprays and stops only the frequency | count that spraying spreads from the rotating discharge outlet 550u to the inner surface of a toilet bowl, and is not limited to one reciprocating rotation drive, The user can determine the number of round trips when spraying toilet bowl foam. Can be selected and set by the operation unit 210 or the remote controller 400.

  Further, when the spray nozzle 550 is configured to reciprocally rotate the rotary nozzle 550d of the spray nozzle 550 as shown in FIG. As the rotation nozzle 550d rotates all around in either the right direction or the left direction, the spraying direction of the cleaning water or the cleaning bubbles is not always the same direction, but the reciprocating rotation is reversed by reciprocating rotation. By spraying from two directions and spraying from two directions by this forward / reverse rotation, so-called spray omissions can be reduced, and spraying can be performed more easily. Can do.

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

  The rotation restricting portion (not shown) is a spray nozzle driving portion 550a when a protrusion formed on a part of the outer periphery of the rotating nozzle 550d rotates together with the rotating nozzle 550d and contacts the rotation restricting wall of the body 550c. Even if the motor tries to rotate the rotating nozzle 550d, it is in mechanical contact with the motor, so that the rotating nozzle 550d cannot rotate only by slipping and idling the motor.

  Thus, by providing a rotation restricting portion (not shown) for restricting the rotation range and rotating the spray nozzle 550 in a reciprocating range that is not restricted by the rotation restricting portion, the reciprocation from the reverse direction due to the reciprocation is achieved. By spraying and spraying from two directions by this forward / reverse rotation, so-called spray omissions can be reduced and more easily sprayed, so it is possible to suppress the adhesion of dirt with a small number of sprays (time). .

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

  As described in the water circuit configuration according to FIG. 6, the branch flow path 530 branched between the water pump 516 serving as the water discharge amount varying means and the flow control valve 517 in the cleaning water supply flow path 690 is opened and closed. The washing water is supplied to the foam tank 532 via the valve 530 a and the check valve 531, and the spray nozzle 550 is connected downstream of the foam tank 532. A detergent tank 533 that supplies detergent to the foam tank 532 and a detergent pump 534 are connected, and an air pump 535 that feeds air into the foam tank 532 and creates washing foam is provided.

  Incidentally, when the control unit 130 opens the on-off valve 530a, the cleaning water from the heat exchanger 700 is fed by the water pump 516 that is a discharge amount varying means, so that the cleaning water or the cleaning foam is discharged from the spray nozzle 550. The At that time, the discharge amount and discharge momentum (discharge speed and discharge amount) of the cleaning water or the cleaning bubbles discharged from the spray nozzle 550 according to the increase / decrease in the output of the water pump (pump) 516 and the air pump 535 which are the water discharge amount variable means. The discharge pressure is increased or decreased.

  In addition, the configuration in which the on-off valve 530a is provided in the branch flow channel 530 may be a configuration in which a flow path switching valve is provided in a branch portion of the branch flow channel 530 and the washing water supply flow channel 690.

  The user can select whether to spray the cleaning water from the spray nozzle 550 or spray the cleaning foam by the operation unit 210 of the main body 200 or the remote controller 400. It is provided with a foam tank 532 that generates cleaning bubbles by supplying detergent between the on-off valve 530a and the spray nozzle 550, and the cleaning foam is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet. In addition, not only a simple water film is formed by spraying water or hot water, but also the effect of suppressing the adhesion of dirt can be further enhanced by forming a foam film by washing bubbles containing a detergent. Moreover, the foam film by the washing | cleaning foam containing a detergent can suppress unpleasant smell and can improve the comfortable feeling of a visually clean image.

  In the sanitary washing device of the present embodiment, the washing water or the washing foam is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl separately from the case where the human body detection sensor 450 detects the person entering the room. By operating the spraying switch 417 of the controller 400, spraying can be performed, and whenever a dirt is anxious, a foam film with a cleaning foam including a detergent can be formed and cleaned.

  In addition, whether the washing water or the washing foam is sprayed from the spray nozzle 550 to the inner surface of the toilet is arbitrarily selected by the user in advance by the spray selection switch (not shown) of the operation unit 210 or the remote controller 400. be able to.

  The control unit 130 also has a cedar command mode that can be selected and instructed by the switch button of the operation unit 210 or the remote controller 400, and supplies the detergent in the detergent tank 533 of the foam generation unit 560 to the foam tank 532 in the cedar command mode. The opening / closing valve 530a may be opened with the detergent pump 534 stopped, and the cleaning water may be supplied to the foam tank 532 by the water discharge amount variable means 516 and discharged from the spray nozzle 550.

  Thereby, the path from the foam tank 532 to the spray nozzle 550 is rinsed by the washing water, and the clogging due to the adhesion of the detergent on the path and the spray nozzle 550 and the rotation failure due to the adhesion of the detergent on the spray nozzle 550 can be prevented. . Moreover, the inner surface of the toilet bowl can be rinsed.

  That is, since the detergent pump 534 is stopped during this rinsing operation, the cleaning water is sent without being supplied to the foam tank 532, and the path from the foam tank 532 to the spray nozzle 550 is rinsed by the cleaning water. And the inner surface of the toilet bowl can be rinsed with washing water.

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

The user can perform rinsing at any time by operating the cedar switch 223 of the operation unit 210 to enter the cedar issue mode.

  In addition, a cedar lamp 223a such as an LED is provided in the vicinity of the cedar switch 223 of the operation unit 210 to be in the cedar issuing mode, and the control unit 130, for example, when a predetermined time such as 20 days elapses after the previous rinsing, Forgetting to rinse can be prevented by the configuration in which the cedar lamp 223a automatically blinks.

  When the cleaning foam is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl, the control unit 130 controls the air pump according to the rotation angle of the discharge port 550u of the spray nozzle 550 in the same manner as the pump output shown in FIG. The output of 535 may be changed. As a result, even if the distance to the front, side, and rear of the toilet is different, the cleaning foam can be discharged so as to reach the entire inner surface of the toilet. Can be suppressed.

  That is, when the rotation angle at which the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl is the longest (longest) is about 160 °, the output of the air pump 535 becomes large, so that the air pressure by the air pump 535 increases. When the rotation angle at which the distance from the discharge port 550u to the inner surface of the toilet is the closest (short) is about 340 °, the output of the air pump 535 is small. Accordingly, the air pressure by the air pump 535 is lowered, and the force to blow the washing bubbles is weakened, so that the washing bubbles can be uniformly discharged to the inner surface of the toilet.

  In addition, the image sensor or the like is further provided with a dirt detection means (not shown) for detecting the dirt on the toilet bowl, and the control unit 130 scatters the remaining part of the toilet in a reciprocating manner in a concentrated manner. The suppression effect can be improved. In addition to the method of partially reciprocating the dirt portion, the rotation speed when the discharge port 550u of the spray nozzle 550 rotates through the dirt portion may be rotated at a low speed or the pump output may be increased.

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

  In this case, since the user is in the standing posture and the toilet seat 300 is opened, the signal of the toilet seat opening / closing detection unit 331 is the toilet seat open state, and the signal of the seating detection unit 330 is the non-sitting state. When the spray switch 417 is pressed by the user, as shown in FIG. 37, the control unit 130 moves the position of the discharge port 550u of the spray nozzle 550 toward the toilet outlet 115 (in this embodiment, FIG. 37, the spray nozzle drive unit 550a is rotated and stopped until the rotation angle of the discharge port 550u is about 150 ° as shown in the chart of FIG. As indicated by the arrow, the washing foam is discharged to the toilet outlet 115 for a predetermined time (in this embodiment, 8 seconds). The discharged washing bubbles cover the water surface above the outlet 115 of the toilet 110, that is, the upper surface of the so-called draft surface in the toilet.

  With the rotating foam spraying mode (foam coating) mode of the control unit 130 described in <7> above, the rotating foam spraying spraying the cleaning foam into the toilet bowl while rotating the direction of the discharge port 550u of the spray nozzle 550 is performed. The item <8> is fixed foam spraying in which the cleaning foam is sprayed into the toilet bowl while the direction of the discharge port of the spray nozzle is fixed by the fixed foam spraying instruction (splash suppression) mode of the control unit 130.

As described above, in the state where the user is not seated on the toilet seat 300 as in the case of male urine and the toilet seat 300 is opened almost vertically, the manual operation that is the spray switch of the operation unit 210 or the remote controller 400 When the splash suppression switch 434 is operated, as shown in FIG. 37, the control unit 130 positions the discharge port 550u of the spray nozzle 550 toward the rear of the toilet bowl (in the present embodiment, the chart of FIG. As shown in FIG. 37, after the spray nozzle drive unit 550a is rotated and stopped until the rotation angle of the discharge port 550u is about 20 °), the water discharge amount variable means 516 is controlled at a high output, and the washing bubble is indicated by the arrow in FIG. Is discharged to the back of the toilet bowl for a predetermined time (in this embodiment, 8 seconds).

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

  In this way, after the direction of the discharge port 550u of the spray nozzle 550 is driven to rotate backward in the toilet bowl, the water discharge amount variable means 516 is controlled at a high output, and the washing foam is placed on the water surface above the outlet 115 in the toilet bowl and in the toilet bowl. The upper part of the water line can be quickly covered with foam, and the odor and the adhesion of dirt near the water surface of the toilet can be suppressed by the cleaning foam. Moreover, when the urine falls to the vicinity of the water surface in the toilet bowl, bounce back to the surroundings can be suppressed by the cushion effect of the foam covering the water surface. That is, it is possible to prevent the urine from splashing and scattering by quickly spraying a large amount of bubbles in the direction in which the spray nozzle 550 is fixed and forming bubbles on the upper surface of the water in the toilet.

  In the present embodiment, when the user operates the manual splash suppression switch 434 of the remote controller 400 during male urination, the control unit 130 enters the fixed bubble spraying instruction (splash suppression) mode and the discharge port 550u of the spray nozzle 550. The spray nozzle driving unit 550a is rotated and stopped until the direction of the nozzle is directed to the toilet outlet 115, and then the water discharge amount variable means 516 is controlled with a high output so that the washing bubbles are discharged toward the rear of the toilet. Although it was set as the structure, the position where washing foam is fixedly sprayed may be any of the front side, the center, and the rear side of the toilet near the outlet 115.

  That is, by quickly covering the draft surface and the upper part of the toilet bowl water line with foam in a short time of a few seconds after the start of the discharge of the washing foam, it is possible to suppress splashing and scattering of urine, and the vicinity of the draft line in the toilet bowl and The adhesion of dirt on the upper part can be suppressed.

  In this fixed bubble spraying instruction (splash suppression) mode, in the fixed foam spraying in which the cleaning foam is sprayed into the toilet while the direction of the discharge port of the spray nozzle is fixed, in FIG. 37, the water discharge amount variable means 516 is controlled at a high output. Although the cleaning foam is discharged toward the toilet outlet 115, the output of the water pump 516, which is the water discharge amount variable means, is not changed in the same manner as the rotating foam spraying described in the section <7>. The output, that is, the output of the water pump 516 that is the water discharge amount varying means at the time of spraying fixed bubbles may be the same as that at the time of spraying the rotating bubbles.

As described above, the sanitary washing device according to the present embodiment includes the main body 200 installed in the toilet 110, the washing nozzle 831 for washing the human body, the foam generating unit 560 that generates washing bubbles, and the washing water or A spray nozzle 550 that discharges cleaning bubbles, a water discharge amount varying means 516 that varies the flow rate of cleaning water sent to the spray nozzle, a spray nozzle driving unit 550a that rotationally drives the direction of the discharge port 550u of the spray nozzle, and a spray nozzle An on-off valve 530a for opening and closing the water channel to the control unit, a control unit 130 for controlling these operations, and an operation unit 210 for instructing and setting the control unit. The control unit 130 changes the direction of the discharge port 550u of the spray nozzle. Rotating foam spraying mode (foam coat) mode that sprays cleaning foam into the toilet while rotating, and spraying the cleaning foam into the toilet with the direction of the spray nozzle outlet 550u fixed When the toilet foam is sprayed from the spray nozzle 550 to the toilet bowl, the direction of the discharge nozzle 550u is rotationally driven and the cleaning foam is widely spread in the toilet bowl. It is sprayed so that it can reach, and a foam film can be formed from the front of the toilet to the inner surface of the rear to suppress the adhesion of dirt on the toilet inner surface and the vicinity of the water line.

  Also, the fixed foam spraying mode that sprays the washing foam into the toilet bowl while fixing the direction of the discharge port 550u of the spray nozzle quickly forms the cleaning foam above the water surface in the toilet bowl, and the water surface above the discharge outlet in the toilet bowl. Can be covered with the washing foam, so that the washing foam can suppress the unpleasant smell at the time of urination and the splash at the time of male urination.

  In addition, as a result of the verification experiment about the scattering suppression effect due to honey at the time of male urination, as shown in FIG. 49, there is an effect that the thickness of the foam, which is the height of the foam, is improved from about 5 mm compared to no foam, It was confirmed that the suppression effect became significant when the foam thickness was about 10 mm. That is, it is preferable that the lower limit of the thickness of the foam on the water surface in the toilet bowl is 5 mm or more and the upper limit is 50 mm or less. In addition, 50 mm or less is an upper limit by making it the bubble height which the bubble which accumulate | stored does not stick to buttocks when a user sits on a toilet seat.

  Further, in the sanitary washing device of the present embodiment, the spray nozzle 550 is installed in the main body 200 with the rotation axis Ax of the discharge port 550u of the spray nozzle driven to rotate tilted in the front-rear direction and the left-right direction, and the front-rear direction The inclination of the rotation axis Ax is inclined to the front side of the toilet bowl 110, and the inclination in the left-right direction is inclined to the cleaning nozzle 831 side of the rotation axis Ax. When foam is sprayed, when the discharge port 550u is directed in front of the toilet where the distance from the discharge port 550u of the spray nozzle to the spray position is far away, the direction of the discharge port 550u becomes higher, and the distance from the discharge port 550u of the spray nozzle to the spray position is increased. When the discharge port 550u is directed to the rear of the toilet, the distance of the discharge port 550u is lowered. In this way, the cleaning foam can be sprayed while the height of the spray nozzle discharge port 550u changes with the distance from the spray nozzle discharge port 550u to the inner surface of the toilet bowl. Even without changing the output, a foam film can be formed from the front of the toilet to the rear inner surface to suppress the adhesion of dirt.

  Further, in the sanitary washing device of the present embodiment, when the rotating foam is sprayed from the spray nozzle 550 to the toilet 110, the control unit 130 rotates the spray nozzle driving unit 550a in the normal direction so that the direction of the spray nozzle outlet 550u is the toilet bowl. Rotating foam is sprayed by at least one reciprocating rotation operation from the rear through the toilet bowl to the rear of the toilet bowl, by rotating the spray nozzle driving unit 550a so that the direction of the spray nozzle outlet 550u returns from the toilet bowl back to the toilet bowl from the front of the toilet bowl. When rotating foam spraying the cleaning foam from the spray nozzle 550 to the toilet bowl with the configuration having the process, the control unit 130 causes the spray nozzle driving unit 550a to rotate forward so that the direction of the spray nozzle outlet 550u is from the rear of the toilet bowl. After passing through the front of the toilet and reaching the rear of the toilet, the spray nozzle driving unit 550a is reversed so that the direction of the spray nozzle outlet 550u is after the toilet. The output of the water discharge amount variable means is controlled so that the cleaning foam reaches the vicinity of the toilet rim while being driven at least one reciprocating rotation from the front of the toilet to the rear of the toilet. A foam film can be formed from the front of the toilet to the rear inner surface to suppress the adhesion of dirt.

  In addition, the sanitary washing device according to the present embodiment further includes a human body detection sensor 450 that detects the entry / exit of the user into / from the toilet room, and the control unit 130 controls the human body detection sensor 450 to enter the user's room into the toilet room. When detected, when the human body detection sensor 450 detects that the user has entered the toilet room, the direction of the discharge port 550u of the spray nozzle rotates at least one reciprocating motion. While being driven, the rotating foam can be sprayed on the inner surface of the toilet, and a foam film can be reliably formed on the inner surface of the toilet before use to suppress the adhesion of dirt.

Further, in the sanitary washing device of the present embodiment, the control unit 130 opens the on-off valve 530 a so that the washing water is fed by the water discharge amount varying means 516 and the detergent in the detergent tank 533 is sent to the foam tank 532. A detergent pump 534 for supplying air and an air pump 535 for supplying air to the foam tank, and the surface of the cleaning nozzle 831 or the inner surface of the toilet bowl is configured so that the cleaning water or the cleaning foam in the foam tank 532 is discharged from the spray nozzle 550. In this case, not only water or hot water is discharged, but also cleaning bubbles including a detergent are discharged, so that the cleaning effect and the effect of suppressing dirt adhesion can be enhanced. In addition, an unpleasant odor can be suppressed by the washing foam containing the detergent, and a visually clean and comfortable feeling can be improved.

  In the sanitary washing device of the present embodiment, the control unit 130 has a cedar command mode, and the detergent pump 534 that supplies the detergent in the detergent tank 533 of the foam generation unit 560 to the foam tank 532 is stopped in the cedar command mode. In such a state, the on-off valve 530a is opened, and the washing water is supplied to the foam tank 532 by the water discharge amount varying means 516 and discharged from the spray nozzle 550, so that the path from the foam tank 532 to the spray nozzle 550 is rinsed by the wash water. It is possible to prevent clogging due to sticking of the detergent on the path and spray nozzle 550 and rotation failure due to sticking of the detergent on the spray nozzle. Moreover, the inner surface of the toilet bowl can be rinsed.

  In this embodiment, a motor is used as the spray nozzle driving unit 550a. However, the spray nozzle 550 is rotated by an action when another cleaning source, for example, the discharge bubbles 550u of the spray nozzle 550 is discharged. You may comprise.

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

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

  In the present embodiment, the spray nozzle 550 is configured to spray in the vicinity of the toilet rim and in the vicinity of the toilet outlet 115, but in addition to the vicinity of the toilet rim and the vicinity of the toilet outlet 115, Further, it may be dispersed at other positions.

  Further, as shown in FIGS. 34, 38, and 39, the sanitary washing device according to the present embodiment is integrally provided with a sleeve case 250 so as to protrude forward from the side of the main body 200. A sleeve lid 217 provided in front of the operation unit 210 disposed in the upper part of the case 250, and a transparent or translucent container of the foam generating unit 560 at the forefront of the sleeve case 250 inside the sleeve lid 217. The detergent tank 533 is built in, and the detergent liquid level confirmation window 216 for visually confirming the detergent liquid level position of the detergent tank 533 is provided on the front surface of the sleeve case 250. Since the remaining amount of the detergent can be easily visually confirmed when performed before, the detergent can be replenished before the detergent runs out.

  As described above, the detergent tank 533 having the detergent inlet 537 provided with the detergent tank lid 536 is installed at the forefront portion in front of the operation portion 210 of the sleeve case 250 and is located closest to the front of the toilet bowl. Therefore, it is possible to facilitate replenishment of the detergent. In addition, since the detergent tank 533 having the detergent inlet 537 is installed in the forefront portion in front of the operation portion 210 of the sleeve case 250, the sleeve lid 217 in front of the operation portion 210 is opened, and the detergent injection is performed. When the detergent is replenished from the inlet 537 to the detergent tank 533, the detergent can be prevented from falling into the operation unit 210. Further, as shown in FIGS. 38 and 39, the detergent injection port 537 is configured such that the height position of the detergent injection port 537 is lower than that of the operation unit 210. It is possible to prevent the portion 210 from falling down.

  Further, in the sanitary washing apparatus of the present embodiment, the detergent pump hose 561 shown in FIGS. 6 and 38 is a hollow cylindrical tube through which the detergent is led from the outlet side of the detergent pump 534 to the inlet side of the foam tank 532. There is a so-called double hose in which the tube is further coated on the outside of the tube. The inner diameter of the detergent pump hose 561 is smaller than the inner diameter of the foam tank hose 562 that guides the cleaning foam from the foam tank 532 to the spray nozzle 550. With the above configuration, even when a high pressure from the detergent pump 534 is applied, the detergent pump hose 561 can be prevented from greatly expanding or bursting, and the cleaning foam can be stably sprayed from the spray nozzle 550. .

  Incidentally, in the sanitary washing apparatus of the present embodiment, the detergent pump hose 561 having a double hose structure is configured by a double hose in which the outer side of the elastomer resin tube is covered with a heat shrinkable tube, but the material is not limited to this. Even if it is other material which is not, by using a double hose, swelling and bursting can be prevented, and the cleaning foam can be stably sprayed from the spray nozzle 550.

  Further, as can be seen from FIGS. 2, 39 and 40, the sanitary washing device of the present embodiment includes a main body 200 having a control unit 130, a spray nozzle 550, a nozzle device and the like inside the rear main body case 201. The front surface is covered with a main body case 202.

  And the spray nozzle 550 is installed in the front part of the rear main body case 201, the front and upper part of the spray nozzle 550 are covered with the main body case 202, and the discharge port 516e of the lower part of the spray nozzle 550 is opened to the inner surface of the toilet bowl. It is installed at.

  40 is a cross-sectional view showing a central portion of the spray nozzle 550 installed in the rear main body case 201 cut in the front-rear direction. The cleaning foam discharged from the spray nozzle 550 through the discharge port 516e is normally discharged onto the inner surface of the toilet as shown by the dotted line T in FIG. However, in the case of rinsing by the above-mentioned cedar issuing mode, when washing water that does not contain detergent and is free of bubbles is discharged from the discharge nozzle 550e through the discharge port 516e, a two-dot chain line S in FIG. As shown, the jets may diffuse and scatter, causing the problem of splashing out of the toilet and wetting the floor.

  As shown in FIG. 40, in the sanitary washing device of the present embodiment, the body case 202 is formed with a splatter guard portion 550z that blocks an upward jet flow exceeding the upper limit from the discharge port 516e of the spray nozzle 550 with a wall and drops it into the toilet bowl. Has been. By the splash guard part 550z that blocks the upward jet flow exceeding the upper limit from the discharge port 516e, it is possible to prevent the cleaning foam and the cleaning water discharged from the spray nozzle 550 from being ejected outside the toilet, and can be sprayed into the toilet.

  That is, a part of the main body case 202 of the main body 200 that covers the front and top of the spray nozzle 550 has a splash guard portion 550z that blocks the upward jet flow from the discharge port 550u of the spray nozzle 550 and drops it into the toilet bowl. Thus, it is possible to prevent the washing bubbles and washing water discharged from the spray nozzle 550 from being ejected outside the toilet bowl.

  Moreover, the splash guard part 550z formed in the main body case 202 not only prevents the washing bubbles and washing water discharged from the spray nozzle 550 from being ejected outside the toilet bowl. The sanitary washing apparatus has a configuration in which the main body 200 can be attached to and detached from the toilet 110 via the main body fixing plate 240. The main body of the sanitary washing device removed when the contractor or the user initially installs the toilet in the toilet bowl, or when the user wants to remove the main body 200 from the toilet bowl 110 and clean the dirt near the bottom of the main body 200. 200 may be temporarily placed on a table or on the floor.

Thus, when the main body 200 of the sanitary washing apparatus is temporarily placed on the table or on the floor, the discharge port 516e of the spray nozzle 550 positioned below the attachment surface of the main body 200 is scattered and the guard portion 550z is scattered. Therefore, it is possible to protect the spray nozzle 550 from being in contact with the base and the floor, and to prevent the spray nozzle 550 from being damaged. A two-dot chain line in FIG. 41 showing a front view of the main body 200 and FIG. 42 showing a side view of the main body 200 shows the surface of the table when the main body 200 is placed. As shown in FIG. 41 and FIG. 42, the discharge port 516e of the spray nozzle 550 does not come into contact with the surface of the table by the scattering guard portion 550z.

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

  FIG. 43 is a perspective view of the main body fixing plate 240 and the rear main body case 201 of the main body 200 described above. The perspective view of the rear main body case 201 is a diagram in which the control unit 130, the spray nozzle 550, the nozzle device, and the like installed therein are omitted for convenience of explanation.

  The main body fixing plate 240 is fixed to the toilet bowl through a mounting bolt (not shown) in the position adjusting long hole 241. Then, the center of the main body fixing plate 240 and the main body 200 are aligned, the rear portion of the main body fixing plate 240 is slightly lifted, and the main body 200 is slid from the toilet surface until it clicks into place. It is the structure fixed to.

  Moreover, when removing the main body 200 from the toilet bowl 110, it is the structure which can be removed if it pulls out the main body 200 ahead, pushing in the main body attachment / detachment button 242 beside the main body 200 to the back with a finger | toe.

  43, a magnet 243 is embedded in the resin main body fixing plate 240, and the main body 200 is attached to the toilet bowl 110 in the rear main body case 201 or the main body 200 is attached to the toilet bowl 110. An attachment / detachment sensor 244 that can detect whether it is removed from the camera is attached.

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

  The controller 130 is configured such that the discharge operation from the spray nozzle 550 is not executed when the attachment / detachment sensor 244 detects that the main body 200 has been removed from the toilet 110. As a result, when the main body 200 is removed from the toilet 110, for example, a button for instructing a discharge operation from the spray nozzle 550 such as the manual foam coat switch 433 or the manual splash suppression switch 434 of the remote control main body 401 is pressed. However, since the discharge operation from the spray nozzle 550 is not executed, it is possible to prevent a problem that the cleaning bubbles are inadvertently ejected to the floor or a person.

  In addition, even when the controller 130 recognizes that the main body 200 is removed from the toilet bowl 110 by the attachment / detachment sensor 244, the discharge operation from the buttocks cleaning nozzle 831 and the bidet cleaning nozzle 832 is not prohibited. As a result, even if a failure occurs in the attachment / detachment sensor 244 and a situation in which the main body 200 is misrecognized as being removed from the toilet bowl 110 is a basic function of the sanitary washing device, Butt washing and bidet washing that are important to can be made feasible.

  Moreover, the time chart at the time of spraying rotating foam with the sanitary washing apparatus of this Embodiment was shown in FIG. When the manual foam coat switch 433 of the remote control main body 401 is pressed, the detergent pump 534 reverses for 2 seconds at the time N2 shown in FIG. 45, and then starts normal rotation at the time N3, and the water pump 516 and the air pump 535. Is operated and detergent, water, and air are supplied to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet. By spraying the rotating foam on the inner surface of the toilet, the inner surface of the toilet is less likely to get dirty, and the dirt can be easily removed.

  At this time, the discharge port 550u of the spray nozzle 550 is rotationally driven by a spray nozzle driving unit 550a that is a stepping motor. In the time chart of FIG. 45, the discharge port 550u of the spray nozzle 550 sprays bubbles while rotating forward from the stop position at the time point N3 to the extreme end position at the time point N6, and then the N9 from the extreme end position at the time point N6. Sprinkle foam back while reversing to the current stop position. Then, at the time of N11, the operation of the water pump 516 and the air pump 535 is automatically stopped, and the rotating foam spraying is automatically ended.

  The controller 130 continuously operates the water pump 516 and the air pump 535 between N3 and N11 sprayed with the rotating foam, whereas the detergent pump 534 is normally rotated from N3 to N4 and stopped. Intermittent operation is performed such as normal rotation from N6 to N7 and stop, and normal rotation from N9 to N10. Experiments have shown that it is more preferable to mix detergent, water, and air, and to generate more stable cleaning bubbles, when the detergent pump 534 is operated intermittently than when the detergent pump 534 is continuously sprayed. In this way, stable cleaning foam can be generated by intermittently operating the detergent pump 534 while rotating foam is sprayed. In addition, wasteful use of the detergent can be prevented, and the trouble of supplying the detergent can be reduced.

  Incidentally, in the sanitary washing device of the present embodiment, the detergent pump 534 is operated for 2 seconds during the 6-second period in intermittent operation.

  In addition, in the time chart when rotating foam spraying shown in FIG. 45, the chart of the heat exchanger 700 is drawn with a broken line, but this is from the water pump 516 to the foam tank 532 when rotating foam spraying. When the supplied water is at a temperature lower than 20 ° C., the heat is controlled by the heat exchanger 700 so that the water temperature becomes about 20 ° C., and the water is supplied to the foam tank 532. When the water temperature is low, the foaming property is lowered. However, by supplying the heat exchanger 700 so that the water temperature is about 20 ° C., preferable washing bubbles can be generated in the foam tank 532.

  45, the detergent pump 534 is inverted from N2 to N3 immediately before the point N3 when the rotating foam spraying is started in the time chart when the rotating foam spraying is performed. This is the detergent pump 534. The tube pump is used, and the detergent solution on the outlet side of the tube flows back to the tube portion that was crushed by the roller by the previous reversal, and the crushed portion is restored to a cylindrical shape and then rotates forward. Thus, a stable amount of detergent can be delivered.

  Also, in the time chart for performing the rotating bubble spraying shown in FIG. 45, the spray nozzle driving unit 550a is driven from the stop position until it comes into contact with the origin position from N11 to N14 when the rotating foam spraying ends. Then, after the rotation detection micro switch is pressed and the origin position of the spray nozzle driving unit 550a, which is a stepping motor, is recognized, the driving is controlled by the control unit 130 so as to return to the stop position.

Thus, the origin reset operation of the spray nozzle drive unit 550a causes a slip phenomenon in the stepping motor of the spray nozzle drive unit 550a due to some increase in rotational load, and the rotation amount cannot be driven by the number of drive steps. Even if a misalignment occurs, it is possible to correct and reset the stop position, which is the starting position of the rotating bubble spraying, to start driving. That is, it is possible to spray the rotating foam at a stable position at all times.

  In addition, the rotation detection microswitch that is pressed by the origin reset operation of the spray nozzle driving unit 550a rotates until the rotation detection microswitch is pressed because, for some reason, detergent adheres around the discharge port 550u of the spray nozzle 550. It is possible to detect when driving is no longer possible. That is, when rotating bubbles are sprayed, when a signal for pressing the rotation detection microswitch is not obtained, the cedar lamp 223a can be turned on to notify the user that the cedar switch 223 is required to perform the cedar operation.

  In the sanitary washing device of the present embodiment, the time from the time point N3 at which the rotating foam spraying is started to the time point N12 at which the rotating foam spraying is ended is set to about 15 seconds. For about 15 seconds, the amount of foam accumulated according to the size of the toilet can be changed to about 10 seconds, about 25 seconds, or the like.

  When the time until the rotation detection micro switch is pressed is delayed by about 10% or more with respect to the set rotating bubble spraying time, the cedar lamp 223a is lit up so that it flashes once as “Chika” and “Chika”. The cedar switch 223 is pushed to encourage the cedar operation. In the cedar operation, the washing water heated to about 40 ° C. in the heat exchanger 700 is washed for about 3 minutes. By this cedar operation, the foam generating unit 560 and the spray nozzle 550 are rinsed with washing water, and the sticking and clogging of the detergent to the foam generating unit 560 and the spray nozzle 550 are prevented, and stable foam spraying is performed. Can do.

  If the detergent nozzles 550 are hardened and the movement becomes difficult, and the time until the rotation detection micro switch is pressed is delayed by about 20% or more with respect to the set rotation bubble spraying time, the cedar lamp 223a is set to “Chika, Chika”. , “Chika, Chika” is displayed so as to blink twice, and while pressing the cedar switch 223 to perform the cedar operation, the vicinity of the discharge port 550u of the spray nozzle 550 is urged to be cleaned with a toothbrush or the like.

  In addition, in the time chart when the rotating foam spraying shown in FIG. 45 is performed, the flow path switching chart shows the washing water from the water discharge amount varying means 516 which is a water pump in the water circuit of FIG. The supply destination is switched from the nozzle device 800 side to the bubble generation unit 560 side, and the operation is switched from the bubble generation unit 560 side to the nozzle device 800 side at the time of N11 to N13. That is, at the time of N2 to N3, the flow control valve 517 is closed and the on-off valve 530a is opened, and at the time of N11 to N13, the on-off valve 530a is closed and the flow control valve 517 is opened. Instead of the on-off valve 530a, a flow path switching valve may be provided at a branch point where the branch flow path 530 branches from the cleaning water supply flow path 690, and the flow path switching valve may be used to switch the flow path. Good.

  Moreover, the time chart at the time of a cedar driving | running | working in the sanitary washing apparatus of this Embodiment was shown in FIG.

  When the cedar switch 223 of the operation unit 210 is pressed and the control unit 130 enters the cedar command mode, the supply destination of the cleaning water is switched from the nozzle device 800 side to the bubble generation unit 560 side at the time of N2 to N3. Then, the washing water heated to about 40 ° C. by the heat exchanger 700 with the detergent pump 534 stopped for about 2 minutes from the time N3 to N8 is converted into a foam tank by the water discharge amount varying means 516 that is a water pump. Water is fed to 532 and discharged from the spray nozzle 550. Furthermore, in about 1 minute from the time of N8 to N10, in addition to the washing water heated to about 40 ° C., the washing is performed while the air pump 535 that sends air to the foam tank 532 is operated.

  In this way, at the time of the cedar operation for rinsing and washing, only the washing water is first fed, and the air pump 535 is operated from the middle to rinse while adding air, so that the foam tank 532 and the flow path first remain. Since the detergent component is roughly discharged from the spray nozzle 550 quickly and efficiently by the wash water, and then the momentum of the air bubbles by the air pump 535 is also added, and the detergent component is rinsed to a slight residue. Effective rinsing can be performed in a short time.

  When rinsing and washing for about 3 minutes from time N3 to time N10 are completed, in N10 to N14, a standby operation is performed so that the detergent pump 534 is rotated in the reverse direction so that rotating foam spraying and fixed foam spraying can be performed normally. Operation is automatically terminated.

  Moreover, the time chart at the time of performing fixed bubble dispersion | spreading with the sanitary washing apparatus of this Embodiment was shown in FIG. When the manual splash suppression switch 434 of the remote control main body 401 is pressed, the detergent pump 534 reverses for 2 seconds at the time N2 shown in FIG. 47, and then starts normal rotation at the time N3, and the water pump 516 and the air pump 535. Is operated and detergent, water, and air are supplied to the foam tank 532 to generate cleaning foam. The generated cleaning foam is sprayed from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet. By collecting bubbles on the water surface of the toilet bowl by spraying fixed bubbles on the inner surface of the toilet bowl, it is possible to suppress flying splashes when men are used small.

  The difference between the time chart when performing the fixed bubble spraying shown in FIG. 47 and the time chart when performing the rotating foam spraying previously described in FIG. While the direction of the discharge port 550u is rotationally driven by the 550a, when performing the fixed bubble spraying, the spray nozzle driving unit 550a sprays the fixed bubble while being fixed without rotating the direction of the discharge port 550u. Is a point. The time chart of FIG. 47 is the same as the time chart of FIG. 45 except for the above, and the description overlapping with FIG. 45 is omitted.

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

  47, when an instruction for spraying fixed bubbles is issued, the spray nozzle driving unit 550a immediately stops the direction of the discharge port 550u from the right behind while stopping at a stop position of about 60 degrees. It is sprayed with fixed foam. In this way, the spray nozzle 550 moves immediately after the fixed bubble spraying is instructed in the state where the spray nozzle driving unit 550a is driven and the direction of the discharge port 550u is in a standby state at a stop position of about 60 degrees in advance. Without operation, it is possible to immediately discharge the cleaning foam on the inner surface of the toilet and quickly form the foam height necessary to suppress the splash on the water surface in the toilet before the men's use is started. In particular, by setting the direction of the discharge port 550u at the stop position to the position of 50 to 70 (about 60) degrees where the washing foam hits the slope of the inner surface of the toilet bowl and flows down to the water surface so as to rotate on the slope of the toilet bowl. The cleaning foam can be quickly formed on the entire water surface.

  In addition, the sanitary washing device according to the present embodiment automatically applies the rotating foam spray described in FIG. 45 not only when the manual foam coat switch 433 of the remote control body 401 is pressed but also after the use of the toilet, that is, after the use of the toilet. Can be set to sprinkle with rotating foam. Furthermore, it can be set so that the rotating bubbles are automatically sprayed at regular intervals. By spraying the rotating foam automatically after using the toilet or at regular time intervals, the inner surface of the toilet is less likely to get dirty, and the dirt can be more easily removed. In addition, by automatically spraying the rotating foam at regular intervals, it is possible to suppress dirt, particularly fringes, near the waterline in the toilet.

  In the sanitary washing device according to the present embodiment, when automatic operation is set to spray rotating foam after using the toilet, the seating sensor 330 detects when the user stands up from the toilet seat 300, and about 15 seconds after about 60 seconds. Rotating foam is sprayed. For small men who are not seated on the toilet seat, the toilet seat opening / closing sensor 331 detects that the toilet seat 300 is closed, and after about 60 seconds, a rotating foam spray is applied for about 15 seconds.

  In addition, after about 60 seconds, the configuration can be changed to about 10 seconds or 25 seconds after the switch of the remote control body 401, and the rotating foam spraying is started after the user stands up from the toilet seat. Can be adjusted to a time that suits the user's usage.

  In addition, the rotating foam spraying time of about 15 seconds can be changed to 10 seconds, 25 seconds, etc. with the switch on the remote control main body 401, and the amount of foam accumulated according to the size of the toilet can be adjusted. Can do.

  In the sanitary washing device of the present embodiment, the fixed foam spraying described with reference to FIG. 47 is not only performed when the manual splash control switch 434 of the remote control body 401 is pressed, but is automatically sprayed when the toilet seat is opened. Can be set to When the toilet seat 300 is opened at the time of male use, the fixed foam is automatically sprayed, so that splashing at the time of male use can be suppressed.

  In the sanitary washing apparatus according to the present embodiment, when automatic operation is set to spray fixed foam when the toilet seat is opened, when the toilet seat 300 is opened, the fixed foam is sprayed for about 15 seconds immediately after the toilet seat 300 is opened. .

  In addition, about 15 seconds of the above-mentioned fixed foam spraying time can be changed to 10 seconds, 25 seconds, etc. with the switch of the remote control main body 401, and the amount of foam accumulated according to the size of the toilet is adjusted. can do.

  FIG. 48 shows a configuration for selecting and setting the automatic operation of the above-described stationary foam spraying and rotating foam spraying. Each time the automatic selection setting switch 236 of the operation unit 210 is pressed, a desired setting can be selected. An automatic rotation setting lamp 236a after use, an automatic rotation distribution lamp 236b after every fixed time, and an automatic fixed foam distribution display lamp 236c when the toilet seat is opened are arranged next to the automatic selection setting switch 236. Each time 236 is pressed, the settings for the three types of automatic operation can be changed in the directions indicated by the arrows in FIG.

  H0 when the automatic rotation spray lamp 236a after use, the automatic rotation spray lamp 236b at regular intervals, and the automatic fixed foam spray display lamp 236c when the toilet seat is opened are all turned off, and all of the three types of automatic driving are “off”. Indicates. From this state, when the automatic selection setting switch 236 is pressed once, only the automatic rotating spray lamp 236a after use is turned on. In this way, every time the automatic selection setting switch 236 is pressed, the setting can be shifted to H2, H3... H6, and in H7, all three types of automatic driving can be set to the “ON” state. In the lamp display of FIG. 48, a circle indicates that the lamp is extinguished and the setting is “off”, and a circle indicates that the lamp is on and the setting is “on”.

For example, in FIG. 48, in the case of H2, H4, H6, and H7 that are set to perform automatic operation of rotating foam spraying at regular time intervals, the rotating foam spraying shown in the time chart of FIG. 45 is automatically performed about every 3 hours. It is possible to suppress dirt around the waterline in the toilet bowl, in particular rounding.
It should be noted that the above-mentioned about every 3 hours can be set and changed every about 6 hours, about every 12 hours, every about 24 hours, etc. with the switch of the remote control body 401. It can be adjusted according to the convenience of the user.

(Embodiment 2)
FIG. 51 is a perspective view of the sanitary washing device in the second embodiment. The sanitary washing device according to Embodiment 2 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 apparatus according to the first embodiment is a so-called retrofit type sanitary washing apparatus in which the main body 200 is installed on the toilet afterwards separately from the toilet bowl 110.
The sanitary washing apparatus according to the second embodiment is also provided with a configuration for performing a foam spraying operation in the same manner as the sanitary washing apparatus according to the first embodiment.

  The sanitary washing device of the second embodiment is different from the sanitary washing device of the first embodiment in that after use of the toilet, the post-pouch flush switch 910 or the post-stool flush switch 920 of the remote controller 400 as the operation unit is used. A flush valve 930 (not shown) that can flush the toilet after urination or flush the urinal after urine is provided.

  As shown in H1, H4, H5, and H7 in FIG. 48, when the automatic operation of foaming shown in FIG. 45 is set after a predetermined time after use, the post-stool flush switch operation is performed more than the post-piss flush switch operation. By adopting a configuration in which the amount of foam sprayed on the inner surface of the toilet is increased at the time, it is possible to make it more difficult for the toilet after the stool to easily become dirty.

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

  The sanitary washing apparatus according to the second embodiment has a configuration including a post-pouch flush switch 910 and a post-pouch flush switch 920 of the remote controller 400 that is an operation unit, so that the control unit automatically operates after using the toilet based on the signal. The amount of foam spraying can be changed, and by setting the amount of foam spraying on the inner surface of the toilet bowl greater when operating the flush switch after stool than when operating the flush switch after urinal, , Can be more difficult to stick. Accordingly, it is possible to realize a sanitary washing device that can more accurately disperse foam according to the use scene without waste of detergent, and is less likely to get dirt on the inner surface of the toilet bowl.

  As described above, the sanitary washing device according to the present invention rotationally drives the direction of the foam generating unit that generates the cleaning foam, the spray nozzle that discharges the cleaning water or the cleaning foam to the inner surface of the toilet, and the discharge port of the spray nozzle. When spraying the toilet bowl to be sprayed on the toilet bowl, the spray nozzle drive unit can spray the washing foam so that it spreads widely in the toilet bowl while the direction of the outlet of the spray nozzle is rotated. It is possible to suppress the adhesion of dirt near the toilet inner surface and the water line. In addition, by the configuration in which the thickness of the foam accumulated on the water surface in the toilet is 5 mm or more and 50 mm or less before the control unit starts the operation of spraying the foam to spray the cleaning foam from the spray nozzle into the toilet and automatically stops, It is possible to suppress scattering due to splashes at the time of urination, and it can also be applied to the use of devices equipped with other spray nozzles.
