The water pump 516 which is a water discharge amount variable part is a piston pump which is a positive displacement pump. As shown in FIGS. 14 and 15, the outer shape is substantially L-shaped when viewed from the front, and is substantially cylindrical. The motor unit 516a has a shape (including a cylindrical shape), a link mechanism unit 516b that converts the rotary motion of the motor into a reciprocating motion, and a piston unit 516c that is driven by the reciprocating motion of the link mechanism unit 516b. A water suction port 516d and a discharge port 516e are provided as connection ports on the outer surface of the piston portion 516c.

In the above configuration, when the water pump 516 that is the water discharge amount variable unit is driven, it is generated in the motor unit 516a that performs reciprocating motion and performs only rotational motion as compared to the link mechanism portion 516b and the piston portion 516c. It has a configuration with less vibration.

By driving the motor unit 516a, the piston unit 516c starts reciprocating motion, the cleaning water is sucked from the water suction port 516d, and the cleaning water is discharged from the discharge port 516e. The discharged cleaning water becomes a water flow with an appropriate pulsation as the piston portion 516c reciprocates.

In the above configuration, the outer periphery of the substantially cylindrical motor portion 516a of the water pump 516, which is the water discharge amount variable portion, is surrounded by a foamed resin cushioning member (not shown) having elasticity. And the motor part 516a is inserted in the substantially cylindrical water pump installation part 501a (FIG. 7) provided in the rear part of the chassis 501.

The water pump installation part 501a shown in FIG. 7 is formed with a thin wall thickness, and is formed on the upper part of the rib-like leg part 501b standing from the bottom surface of the chassis 501. Since the water pump installation part 501a is formed with a thin wall thickness, it is possible to obtain an effect of absorbing the vibration of the water pump 516 which is the water discharge amount variable part by the elasticity of the resin.

Moreover, as shown in FIG. 12 and FIG. 13, there are a hot water outlet 712 that is a connection port of the heat exchanger 700 in which the buffer tank 750 is integrally formed, and a connection port of a water pump 516 that is a water discharge amount variable part.

In addition, an effect of improving durability can be obtained.

In particular, the water pump 516 which is a water discharge amount variable part is supported via two different materials, a foamed resin buffer member and an elastic resin forming the water pump installation part 501a. Thereby, the vibration of the frequency of a wide range is absorbed and the transmission of the vibration to a main body can be suppressed effectively.

<3> Configuration of Subtank FIG. 9 is a perspective view illustrating an appearance of the subtank 600 according to the first embodiment of the present disclosure, and FIG. 10 is a cross-sectional view of the subtank 600 viewed from the lateral direction. FIG. 11 is a cross-sectional view of the sub tank 600 cut in the front-rear direction.

As shown in FIG. 9, the sub-tank 600 includes a tank body 610 molded from a resin material, a water level detection sensor 620 (FIG. 6) that detects the level of the 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 a thermistor which is a water temperature detection part which detects the temperature of the wash water supplied in the inside.

The tank body 610 includes a front tank 611 that constitutes a front wall, both side walls, a bottom surface, and a top surface of the tank, a rear tank 612 that constitutes a rear wall of the tank, and an atmosphere disposed on the top surface of the tank body 610.

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 lower part toward the upper part, and the side view shape is formed in a substantially trapezoidal shape with the upper part being thinner than the lower part. It is smaller than the area.

A water inlet 601 is provided at the lower portion 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, and the atmosphere opening portion 613 disposed on the top surface of the tank main body 610 An air opening 603 that communicates the inside and the outside of the tank body 610 is provided. By providing the air release port 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 constantly maintained at atmospheric pressure.

When the interior 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 a water discharge amount variable unit, is also maintained at atmospheric pressure. For this reason, the water pump 516 which is a water discharge amount variable part can supply water without being influenced by fluctuations in water pressure. Therefore, a stable pump function can be exhibited.

A buffer section 613a (FIG. 10) 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 section 613, and washing water suddenly occurs from the open air opening 603 along with bubbles. If the washing water is temporarily stored in the buffer unit 613a, the outflow from the atmosphere opening port 603 is suppressed.

By providing the partition wall 614 and forming the water tank 615 and the storage tank 616, when air is contained in the washing water flowing from the water inlet 601, the air is opened to the atmosphere opening from the upper part of the water inlet 615. It passes through 603 and is discharged to the outside. For this reason, only the wash water which does not contain air can be made to flow into the storage tank 616.

Above the water tank 615, a barrier 617 is provided between the upper surface opening 615a of the water tank 615 and the air opening 613, and protrudes from the side wall of the tank body 610 in a substantially horizontal direction (including the horizontal direction).

In addition, a plurality of rectifying ribs 618 protruding alternately in a substantially horizontal direction (including the horizontal direction) are formed on the surfaces of the tank body 610 and the partition wall 614 facing each other inside the water tank 615. Yes.

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 tank 615 while the flow direction is changed by the rectifying rib 618. At this time, when the pressure of the cleaning water flowing in from the water inlet 601 is high, or when the cleaning water contains a large amount of air and the flow is significantly disturbed, the flow is appropriately rectified by the rectifying rib 618. In addition, air contained in the cleaning water is separated by the vortex generated on the downstream side of the rectifying rib 618.

The washing water that has risen in the water tank 615 and separated from the air passes over the upper end of the partition wall 614 and flows into the storage tank 616 to be stored.

At this time, even when the pressure of the cleaning water flowing in from the water inlet 601 is high, or even when the cleaning water contains a large amount of air and the flow is significantly disturbed, the cleaning water flows upward due to the barrier 617. In other words, since the cleaning water directly hits the atmosphere opening portion 613, it is prevented from flowing out of the sub tank 600 through the atmosphere opening port 603.

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 tank 615, and the separated air passes from the atmosphere opening 603 to the outside of the tank body 610. To be released. Therefore, cleaning 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 the cleaning water supplied from the sub tank 600 to the heat exchanger 700 is mixed with air, bubbles are generated inside the heat exchanger 700, the temperature inside the heat exchanger 700 rises abnormally, and heat is generated. The exchanger 700 may be damaged. In the present embodiment, an effect of preventing damage to the heat exchanger 700 can be obtained by providing the partition wall 614 to prevent air from entering.

By installing the common electrode 621 and the upper limit electrode 623 and the lower limit electrode 624 which are the water level electrodes 622 on different surfaces, it is possible to suppress erroneous detection of residual water adhering to the inner surface of the tank body 610 as stored water. An effect can be obtained.

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 or not the water level electrode 622 is submerged. That is, when washing water flows into the storage tank 616, the water level rises, and the lower limit electrode 624 and the upper limit electrode 623 (or only the lower limit electrode 624) are submerged, the common electrode 621, the lower limit electrode 624, and the upper limit electrode 623 The control part 130 detects a water level by the voltage in between decreasing.

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, thereby preventing air from flowing into the heat exchanger 700.

<6> Control and Operation of Cleaning Unit FIG. 29 is a time chart of the cleaning unit 500 at the time of initial use in the first embodiment of the present disclosure, and FIG. 30 is a normal use in the same embodiment. It is a time chart of the washing | cleaning part 500 at the time.

The basic operation of the cleaning unit 500 is that tap water flowing through the water pipe is supplied to the water supply connection port 510 as cleaning water and the water stop solenoid valve 514 is opened, so that the cleaning water is sent to the sub tank 600. Be paid. The flow rate of the cleaning water flowing in the flow path is kept constant by the constant flow valve 513. The drive of the water stop solenoid valve 514 is controlled by the control unit 130 based on the operation of at least one of the remote controller 400 and the operation unit 210.

The washing water supplied to the sub tank 600 is stored in the sub tank 600 and also supplied to the heat exchanger 700 and the water pump 516 which is a water discharge amount variable section. By driving the water pump 516 that is the water discharge amount variable section, the wash water is supplied to the nozzle device 800 via the flow control valve 517.

The driving of the water pump 516 which is a water discharge amount variable unit is controlled by the control unit 130 based on the operation of at least one of the remote controller 400 and the operation unit 210. The control unit 130 drives the water pump 516 that is a water discharge amount variable unit, starts energization of the flat plate heater 702 of the heat exchanger 700, and starts heating the cleaning water.

The control unit 130 controls the energization to the flat heater 702 based on the detection information of the incoming water temperature sensor 630 and the hot water temperature sensor 730, and maintains the cleaning water at the temperature set by the hot water temperature switch 231 of the operation unit 210. .

The control unit 130 controls the flow control valve 517 based on operation information of at least one of the operation unit 210 and the remote controller 400 to control the bottom cleaning nozzle 831, the bidet cleaning nozzle 832, and the nozzle cleaning unit of the nozzle device 800. Wash water is supplied to any of 833. Accordingly, the cleaning water is ejected from any one of the buttocks cleaning ejection port 834, the bidet cleaning ejection port 836, and the nozzle cleaning ejection port 838.

Next, details of control related to the sub tank 600, particularly water level detection and flow rate detection, which is one of the characteristic configurations of the present embodiment, will be described.

FIG. 29 shows the cleaning unit when it is used for the first time after installation of the sanitary washing device 100 according to the first embodiment of the present disclosure, or when it is reused after the draining operation is performed to prevent freezing. The time chart of each function of the washing | cleaning part 500 at the time of the initial use where the washing water is not stored is shown.

At the time P1 when the operation unit 210 or the cleaning switch (for example, the buttocks cleaning switch 221 or 410) of the remote controller 400 is operated, the control unit 130 starts energizing the water stop electromagnetic valve 514 and supplies the cleaning water. At the same time, the control unit 130 starts driving the water level detection sensor 620. The driving of the water level detection sensor 620 is continued until the buttocks cleaning stop P14.

When the water level detection sensor 620 detects that it is the upper limit water level in P2, the control unit 130 starts time measurement, stops energization of the water stop solenoid valve 514 at a time P3 when a predetermined time has elapsed, and Stop supplying. In the present embodiment, the energization is stopped 2 seconds after the upper limit water level is detected.

At the time point P2 when the upper limit water level is detected, the sub-tank 600 and the heat exchanger 700 are basically full of water, but by continuing the supply for an extra 2 seconds, the heat exchanger 700 and the amount of water discharged The water pump 516 which is a variable part can be more reliably filled with the washing water.

Thereby, in the heat exchanger 700, air can be excluded and the washing water can be surely filled with water, so that the heat exchanger 700 can be prevented from being blown away with safety and durability. Can be improved. Moreover, the water supply function of the water pump 516 which is a water discharge amount variable part can be reliably started by surely supplying wash water to the water pump 516 which is a water discharge amount variable part to be in a full water state.

The control unit 130 starts driving the water pump 516 that is the water discharge amount variable unit at the time point P3 when the energization to the water stop solenoid valve 514 is stopped, and operates the flow control valve 517 so that the nozzle unit 820 operates. Supply of cleaning water to the bottom cleaning channel 835 is started.

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

The washing water supplied to the buttocks washing channel 835 is ejected from the buttocks washing outlet 834. The jetted washing water passes through the jetting 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 tapping 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 advances 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. The jetted cleaning water cleans the inner surface of the nozzle cover 840 and then the nozzle cover from the drain port 845. 840 flows out of 840. In the meantime, since the nozzle part 820 is warmed by the washing water, it is possible to suppress the feeling of discomfort due to the cold water being ejected at the time of 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 washing water supplied to the buttocks washing flow path 835 is ejected from the buttocks washing ejection port 834 and passes through the ejection opening 844 to wash the user's local area. The buttocks cleaning operation is continued until the time point P11 at which the cleaning stop operation is performed.

During the driving of the heat exchanger 700, 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 outgoing hot water temperature sensor 730.

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

At the time point P8 when the upper limit water level is detected, the control unit 130 stops energization of the water stop solenoid valve 514 and starts time measurement, and then the process until time point P9 when the water level detection sensor 620 detects the lower limit water level. Measure time. At the time point P9 when the lower limit water level is detected, the control unit 130 calculates the flow rate by calculating using 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 between the flow rate set for each cleaning strength and the calculated flow rate at the calculation end point P10, the control unit 130 adjusts the output of the water pump 516 that is the water discharge amount variable unit. Correct the flow rate of 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 and the heat exchanger 700 as the water discharge amount variable unit is stopped and the nozzle device 800 performs cleaning. The drive of the nozzle drive unit 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 moved back 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 the water discharge amount variable unit are driven again. After cleaning 820, cleaning is started, and at a time P13 when a predetermined time has elapsed, the drive of the water pump 516 and the heat exchanger 700, which are the water discharge amount variable unit, is stopped, and the post-cleaning ends.

At the time P13 when the post-cleaning of the nozzle unit 820 is completed, the water stop solenoid valve 514 is energized again, the wash water is supplied to the sub tank 600, and at the time P14 when the upper limit water level is detected, the water stop solenoid valve 514 is energized. A series of control of the buttocks cleaning is terminated, and the cleaning section is in a standby state with the sub tank 600 at the upper limit water level.

FIG. 30 shows a time chart during normal use in the first embodiment of the present disclosure when the initial use has been performed before and the sanitary cleaning device 100 in the standby state performs the cleaning operation. It is.

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 has performed the initial use. Is a point.

As shown in FIG. 30, at the time point P20 when the operation unit 210 or the cleaning switch (for example, the buttocks cleaning switch 221, 410) of the remote controller 400 is operated in the standby state where the sub tank 600 is full, the control unit 130. Starts energization of the water pump 516, starts supplying cleaning water, and simultaneously starts energization of the heat exchanger 700 based on the stored data that has already been controlled for the initial operation. 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 when the cleaning operation is performed to the time point when the heat exchanger 700 starts energization is different from the case of the initial use described above. It is the same.

As described above, the sanitary washing device 100 according to the present embodiment has a change in the water level by the water level detection sensor provided in the sub-tank 600 without separately providing a dedicated flow rate sensor for detecting the flow rate in the configuration of the cleaning unit 500. The flow rate is detected by calculation. As a result, the configuration of the cleaning unit 500 can be simplified and the cost can be reduced.

In addition, by correcting the threshold 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 having different conductivity in a wide range can be obtained. It can be used as cleaning water for sanitary cleaning equipment. Thereby, the use range and usability of the sanitary washing device 100 can be improved.

In addition, during the initial use of the sanitary washing device 100, after the sub-tank 600 is detected to be full, water continues to flow for a predetermined time, and after the water pump is driven, the water level detection sensor cancels the detection of the upper limit water level, and heat exchange is performed. Starting energization of the heat exchanger 700 can prevent the heat exchanger 700 from being blown. Thereby, safety and reliability can be ensured at a low cost with a simpler structure than means for preventing air blowing using a flow rate sensor that is generally performed.

<7> Control and Operation of Discharge to Toilet Inner Surface by Spraying Nozzle FIG. 31 is a perspective view showing the appearance of the spraying nozzle 550 in the first embodiment of the present disclosure, and FIG. 32 shows the spraying nozzle 550. 33 is a longitudinal sectional view showing the installation state of the spray nozzle 550, FIG. 34 is a front view showing the installation state of the spray nozzle 550, and FIG. 35 is the spray nozzle. It is a top view which shows the installation position of 550, and the rotation angle of the discharge outlet of the spraying nozzle 550. FIG. FIG. 36 is a chart showing the pump output at the rotation angle of the discharge port 550u of the spray nozzle 550 according to the first embodiment of the present disclosure.

As shown in FIG. 32, the spray nozzle 550 includes an O-ring 550e and an O-ring that can be freely rotated by a spray nozzle driving unit 550a, which is a motor, in a body 550c having an inlet channel 550b. The shaft is sealed by 550f. In addition, 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. Can be a thing. 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.

34 and 35, the spray nozzle 550 is installed on the right side of the center of the main body 200. This is because priority is given to placing the buttocks washing nozzle 831 or the like, which is a washing nozzle for washing the human body part, in the center, so that the spray nozzle 550 is arranged not on the center but on the left or right side thereof. Because.

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 while rotating the washing bubbles. The rotating foam spraying instruction (foam coat) mode for spraying in the toilet 110 is entered, the operation shifts to the operation of spraying the rotating foam on the toilet 110, the operation of the water pump 516 as the water discharge amount variable unit is started, and the on-off valve 530a. open.

At this time, the flow control valve 517 that switches the flow path to the buttocks cleaning nozzle 831, the bidet cleaning nozzle 832, the nozzle cleaning unit 833, and the like is in a closed state, so that the cleaning water from the heat exchanger 700 is supplied to the branch flow path. 530, check valve 531 and foam tank 532 are discharged from spray nozzle 550 to the inner surface of toilet 110.

At that time, the control unit 130 drives the spray nozzle driving unit 550a of the spray nozzle 550 to rotationally drive the direction of the discharge port 550u of the spray nozzle 550, and the cleaning water or the cleaning foam discharged from the discharge port 550u. A water film or a foam film is formed around the entire inner surface of the toilet 110.

As shown in FIG. 35, the distance from the spray nozzle 550 to the inner surface of the toilet 110 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, which is a water discharge amount variable unit, according to the rotation angle of the discharge port 550u of the spray nozzle 550.

In the sanitary washing device 100 of the present embodiment, when the direction of the discharge port 550u of the spray nozzle 550 is 160 °, the distance to the toilet inner surface is the longest, and when the direction of the discharge port 550u is 340 °, The distance to the toilet bowl is the shortest.

When the user's entry into the toilet is detected by the human body detection sensor 450, the control unit 130 controls the pump (water pump 516, which is a water discharge amount variable unit) according to the rotation angle of the discharge port 550u of the spray nozzle 550. The output is changed as shown in the chart of FIG.

That is, when the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet is the longest (longer), and the rotation angle is near 160 °, the output of the pump becomes large, and the distance from the discharge port 550u to the inner surface of the toilet is When the rotation angle that is closest (shorter) 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 water is discharged to the front of the toilet, which is the farthest distance from the discharge port 550u of the spray nozzle 550, the cleaning water is discharged with the strongest force and reaches the inner surface of the front of the toilet. In addition, when water is discharged to the rear of the toilet 110, which is the closest distance from the discharge port 550u of the spray nozzle 550, the washing water is discharged with the weakest momentum. Water or washing bubbles can be discharged so as to reach the entire inner surface of the toilet, and a water film or a foam film can be formed up to the inner surface of the front of the toilet, thereby suppressing adhesion of dirt.

A so-called toilet bowl that sprays washing bubbles on the toilet 110 when the human body detection sensor 450 detects that the user has entered the toilet or when the operation unit 210 or the spray switch 417 of the remote controller 400 is operated. Bubbles can be sprayed.

As shown in FIG. 36, the controller 130 rotates the spray nozzle driving unit 550a in the normal direction while changing the output of the water discharge amount variable unit 516, when the toilet foam is sprayed by the toilet foam spraying signal described above. The spray nozzle 550u is driven so that the direction of the discharge port 550u extends from the rear of the toilet bowl to the front of the toilet bowl. Thereafter, the control unit 130 reverses the spray nozzle driving unit 550a, and executes a step of spraying bubbles by at least one reciprocating rotation operation in which the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet bowl to the rear of the toilet bowl. .

As a result, the output of the water discharge amount variable unit is controlled so that the cleaning foam reaches the vicinity of the rim of the toilet 110, and the cleaning foam can be dispersed almost all around the inner surface of the toilet bowl. It is possible to suppress the adhesion of dirt.

In this case, as illustrated in FIG. 36, the control unit 130 causes the output of the water discharge amount variable unit during the normal rotation of the spray nozzle driving unit 550a to be lower than that during the reverse rotation of the spray nozzle driving unit 550a. It is good also as a structure which controls to and discharges a cleaning foam.

By the way, if the output of the water discharge amount variable part is increased, the momentum at which the cleaning bubbles are discharged is strengthened, and the force disperses from the spray nozzle 550 to a location far away, and if the output of the water discharge amount variable part is lowered, the momentum at which the cleaning bubbles are discharged. Is weakened and sprayed to a location near the spray nozzle 550.

As a result, as shown in the scatter movement trajectory indicated by the dotted line in FIG. 35, when the direction of the discharge port 550u of the spray nozzle is rotated forward and backward, it is closer to the draft surface inside the rim of the toilet 110. Cleaning foam is sprayed. Then, as shown in the spray movement trajectory indicated by the broken line in FIG. 35, the washing bubbles are sprayed on the side close to the rim of the toilet 110 at the time of reverse rotation in which the direction of the discharge port 550u of the spray nozzle is driven to reciprocate once.

As a result, at the initial stage of spraying, the draft surface at the top of the outlet of the toilet 110 can be covered with the cleaning foam, and the cleaning foam can be sprayed almost all around the inner surface of the toilet close to the rim. The foam film can be formed up to the inner surface to suppress the adhesion of dirt.

In addition, the installation position of the spray nozzle 550 is located in front of the main body 200 installed on the toilet 110 as shown in FIG. 2, FIG. 33, FIG. 34, FIG. Further, since the spray nozzle 550 is installed further forward than the front tip position of the cleaning nozzle 831 in the state accommodated in the nozzle device 800, the direction of the discharge nozzle 550u of the spray nozzle is driven to rotate. Thus, foam can be sprayed to the rear of the toilet, and a foam film can be formed from the front of the toilet to the inner surface of the rear to suppress adhesion of dirt.

In the above description, the forward rotation is a clockwise rotation when viewed from above in FIG. 35, and the reverse rotation is shown as a counterclockwise rotation. However, the forward rotation is a counterclockwise rotation and the reverse rotation is clockwise. It may be a rotation. 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, when rotating foam is sprayed in the toilet 110, the output of the water pump 516, which is a water discharge amount variable unit, is controlled to change, but the present disclosure is based on this. It is not limited. Even if the output of the water pump 516, which is the water discharge amount variable part, is not changed when rotating the foam, a foam film is formed from the front of the toilet to the rear inner surface by configuring the spray nozzle 550 as described below. Thus, the adhesion of dirt can be suppressed.

As shown in FIGS. 33 and 34, the spray nozzle 550 is installed in the main body 200 such that the rotation axis Ax of the discharge port 550u of the spray nozzle 550 that is driven to rotate is inclined in the front-rear direction and the left-right direction. Yes. In the front-rear direction, the lower side of the rotation axis Ax is inclined toward the front side of the toilet 110, and in the left-right direction, the lower side of the rotation axis Ax is inclined toward the washing nozzle 831. With such a configuration, when the distance from the discharge port 550u of the spray nozzle 550 to the spray position is increased, or when the discharge port 550u faces the front of the toilet 110, the direction of the discharge port 550u becomes higher, and the vicinity of the rim in front of the toilet 110 Can wash up to foam. On the other hand, when the distance from the discharge port 550u of the spray nozzle 550 to the spray position becomes short, and the discharge port 550u is directed behind the toilet 110, the direction of the discharge port 550u is lowered.

In addition, when the distance from the discharge port 550u of the spray nozzle 550 to the spray position is slightly longer, or when 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 close to the rim on the left side of the toilet 110. When the cleaning foam can be sprayed and the distance from the discharge port 550u of the spray nozzle 550 to the spray position is slightly closer, the discharge port 550u is directed to the right side of the toilet 110, the direction of the discharge port 550u is slightly lowered.

As described above, when rotating foam is sprayed from the spray nozzle 550 to the toilet 110, the direction of the discharge port 550u of the spray nozzle 550 is rotationally driven around the rotation axis Ax by the spray nozzle driving unit 550a. . With the rotation of the spray nozzle 550, the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl changes, but with the rotation, the washing bubbles are sprayed while the height of the discharge port 550u of the spray nozzle 550 changes. Therefore, it is possible to form a foam film from the front of the toilet bowl to the inner surface near the rear rim, with a scattering locus as depicted by the counterclockwise broken arrow in FIG. Can be suppressed.

In addition, since the rotating foam spraying is performed with a constant output that does not change the output of the water pump 516 that is the water discharge amount variable section, the same locus as the counterclockwise broken arrow in FIG. Scattered to follow the direction.

Incidentally, in this embodiment, as shown in FIG. 33, the rotation axis Ax of the discharge port 550u of the spray nozzle 550 has an inclination angle β (angle with respect to the vertical direction) of 20 degrees, as shown in FIG. The horizontal inclination angle γ (angle with respect to the vertical direction) is 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, according to the configuration in which the control unit 130 changes the output of the pump according to the rotation angle of the discharge port 550u of the spray nozzle 550, the distance to the front, side, and rear of the toilet is different. Even if the cleaning water or the cleaning foam can reach the wide area of the inner surface of the toilet, the water film or the foam film can be formed on the wide area of the inner surface of the toilet to suppress the adhesion of dirt. .

Note that a level change switch that can adjust the pump output level (average level) 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 cleaning water or the cleaning foam can be discharged so as to reach the entire inner surface of the toilet, and the water film or the foam film is formed to the inner surface in front of the toilet. Adhesion can be suppressed.

As described above, in addition to the controller 130 changing the output of the pump in accordance with the rotation angle of the discharge port 550u of the spray nozzle 550, the control unit 130 sets the rotation angle of the discharge port 550u of the spray nozzle 550 to the rotation angle. Accordingly, the speed of the spray nozzle driving unit 550a may be changed. By changing the output of the pump (water pump 516, which is a water discharge amount variable part), the momentum of the discharge can be changed to reach the inner surface of a distant toilet, and the scattering on the inner surface of a close toilet can be suppressed. By changing the speed of the spray nozzle driver 550a in accordance with the rotation angle of the discharge port 550u, the spray density can be made more uniform.

That is, when the discharge port 550u of the spray nozzle 550 is rotated at a constant rotational 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. Then, the spraying density becomes dense.

By changing the output of the pump (water pump 516 which is a water discharge amount variable part), there is also an effect of making the distribution distribution uniform, but by changing the speed of the spray nozzle drive part 550a according to the rotation angle, it is more In other words, it can be discharged more evenly on the inner surface of the toilet.

For example, in the case of the rotation angle shown in FIG. 35, the washing water or the washing bubbles sprayed forward of the toilet 110 is dispersed when the rotation angle that is the farthest from the discharge port 550u of the spray nozzle 550 is around 160 °. Then, when the spraying density is discharged to the front of the toilet bowl, the spraying nozzle 550 has the slowest rotation speed, thereby increasing the spraying density. On the other hand, when discharging to the rear of the toilet whose rotation angle is the closest distance from the discharge port 550u of the spray nozzle 550, the spray nozzle 550 has the fastest rotation speed, thereby reducing the spray density. Can be made. In this way, the distribution of the cleaning water or the cleaning foam sprayed on the inner surface of the toilet bowl can be made more uniform, and dirt adhesion can be suppressed.

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 is the distance to the inner surface of the toilet bowl. When the rotation angle of the front of the toilet bowl is long, the speed of the spray nozzle driving section 550a is made small, and when the rotation angle is short at the rear of the toilet bowl and the rotation angle is behind the toilet bowl, the speed of the spray nozzle driving section 550a is made large. Can do. As a result, even if the distance to the front, side, and rear of the toilet is different, washing water or washing bubbles can be discharged evenly to the inner surface of the toilet, and more uniformly, to the inner surface in front of the toilet A dirt film can be suppressed by forming a water film or a foam film.

The controller 130 sprays the cleaning foam from the spray nozzle 550 to the inner surface of the toilet after the human body detection sensor 450 detects the person entering the room. While rotating at least one reciprocating rotation, bubbles are sprayed and automatically stopped.

By such an operation, when the user enters the toilet room, a foam film can be formed on the inner surface of the toilet before use, and the adhesion of dirt can be suppressed. It should be noted that the configuration is not limited to the above-described one-time reciprocating rotation drive, and is not limited to the above-described one-way reciprocating rotational drive, as long as it is applied to the inner surface of the toilet from the rotating discharge port 550u. The number of times can be selected and set by the user using at least one of the operation unit 210 and the remote controller 400.

Further, the spray nozzle 550 is configured to reciprocally rotate the rotating nozzle 550d of the spray nozzle 550 as shown in FIG. 36 when spraying cleaning water or cleaning foam on the inner surface of the toilet. Thereby, the spraying direction of the cleaning water or the cleaning foam is not always the same as in the configuration in which the rotating nozzle 550d of the spraying nozzle 550 is rotated all around in the right direction or the left direction. By reciprocating rotation, spraying from the opposite direction by reciprocation is performed, and by spraying from two directions by this forward / reverse rotation, so-called scattering omission portions can be reduced, and spraying that is more easily spread can be performed. Therefore, it is possible to suppress the adhesion of dirt with a small number of spraying times (time).

In the chart of FIG. 36, after a reciprocating rotation in which the rotation angle 0 ° corresponding to the rear side of the toilet is normally rotated from the rotation angle 0 ° to the rotation angle 340 ° and temporarily stopped, and then the rotation angle 340 ° is rotated backward to the rotation angle 0 ° The action to stop 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 from a rotation angle of 0 ° to a rotation angle of 340 ° by a mechanical stopper.

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 attempts to rotate the rotating nozzle 550d, it is in mechanical contact with the motor, so that the motor slips and idles, and the rotating nozzle 550d cannot rotate.

Thus, by providing a rotation restricting portion that restricts the rotation range and rotating the spray nozzle 550 in a reciprocating range that is not restricted by the rotation restricting portion, spraying from the reverse direction by reciprocation is performed, By spraying from two directions by this forward / reverse rotation, so-called spraying-out portions can be reduced, and spraying can be performed more easily, so that the adhesion of dirt can be suppressed with a small number of spraying times (time).

Further, since the spray nozzle driving unit 550a is configured by a motor and the spray nozzle driving unit 550a can recognize the origin of the rotation position at the position where the rotation restricting unit is in contact, the accuracy of the rotation angle position and the rotation speed is possible. High spraying and extremely low dispersion.

As described in the water circuit configuration according to FIG. 6, the branch flow path 530 branched between the water pump 516 and the flow control valve 517 in the wash water supply flow path 690 that is the water discharge amount variable portion is opened and closed. Via a valve 530 a and a check valve 531, the foam tank 532 is connected so that washing water is supplied, and a spray nozzle 550 is connected downstream of the foam tank 532. A detergent tank 533 for supplying detergent and a detergent pump 534 are connected to the foam tank 532, and an air pump 535 for sending air to the foam tank 532 and creating washing foam is provided.

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 the water discharge amount variable unit, and the cleaning water or the cleaning bubbles are discharged from the spray nozzle 550. At that time, the discharge amount of the cleaning water or the cleaning foam discharged from the spray nozzle 550 and the momentum of discharge (in accordance with the increase or decrease of the output of the water pump (pump) 516 and the air pump 535 which are the water discharge amount variable section ( (Discharge speed and discharge pressure) are increased or decreased.

Note that the configuration in which the on-off valve 530a is provided in the branch channel 530 may be a configuration in which a channel switching valve is provided in a branch portion between the branch channel 530 and the washing water supply channel 690.

The user can select whether to spray the cleaning water from the spray nozzle 550 or spray the cleaning foam by at least one of the operation unit 210 of the main body 200 and the remote controller 400.

Between the on-off valve 530a and the spray nozzle 550, there is provided a foam tank 532 that supplies detergent and generates cleaning foam, and the cleaning foam is discharged from the outlet 550u of the spray nozzle 550 to the inner surface of the toilet. As a result, not only a simple water film is formed on the inner surface of the toilet bowl by spraying water or hot water, but a foam film is formed by washing bubbles containing detergent, thereby further enhancing the effect of suppressing the adhesion of dirt. it can.

Also, the foam film made of cleaning foam containing detergent can suppress unpleasant odor and improve the comfort of a visually clean image.

In the sanitary washing device 100 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. The spraying can also be performed by operating the spraying switch 417 of 210 or the remote controller 400.

Therefore, when the dirt is worrisome, it is possible to clean the toilet 110 by forming a foam film with a cleaning foam containing a detergent at any time.

Note that whether to spray the cleaning water or the cleaning foam from the spray nozzle 550 to the inner surface of the toilet bowl is previously determined by a user using at least one spraying selection switch (not shown) of the operation unit 210 or the remote controller 400. Can be arbitrarily selected.

In addition, the control unit 130 has a rinsing instruction mode that can be selected and instructed by at least one of the operation unit 210 and the switch button of the remote controller 400. In the rinsing command mode, the control unit 130 opens the on-off valve 530a with the detergent pump 534 supplying the detergent in the detergent tank 533 of the foam generating unit 560 to the foam tank 532 stopped, and the water discharge amount varying unit 516 The cleaning water may be supplied to the foam tank 532 and discharged from the spray nozzle 550.

As a result, the path from the foam tank 532 to the spray nozzle 550 is rinsed with washing water, and the clogging due to the sticking of the detergent on the path and the spray nozzle 550 and the rotation failure due to the sticking of the detergent on the spray nozzle 550 are prevented. be able to. Moreover, the inner surface of the toilet bowl can be rinsed.

That is, at the time of this rinsing operation, the detergent pump 534 is in a stopped state, so that the detergent is not supplied to the foam tank 532 and cleaning water is sent. For this reason, the path from the foam tank 532 to the spray nozzle 550 can be rinsed with the washing water, and the inner surface of the toilet can be rinsed with the washing water.

Further, in this rinsing operation, rinsing can be performed even with washing water whose temperature is not controlled. However, 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. it can.

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

In addition, a rinsing lamp 223a (FIG. 4) such as an LED is provided in the vicinity of the rinsing switch 223 of the operation unit 210 to set the above-described rinsing instruction mode. For example, when a predetermined time such as 20 days elapses, it is possible to prevent forgetting to rinse by making the rinse lamp 223a automatically blink.

When the cleaning foam is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl, the control unit 130, according to the rotation angle of the discharge port 550u of the spray nozzle 550, similar to the case shown in the pump output of FIG. The output of the air pump 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. Dirt adhesion can be suppressed.

That is, when the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet is the longest (longest) and the rotation angle is near 160 °, the air pressure by the air pump 535 is increased by increasing the output of the air pump 535. It becomes high and the momentum which blows a washing bubble far from the discharge outlet 550u can be strengthened. On the other hand, when the distance from the discharge port 550u to the inner surface of the toilet bowl is the shortest (short) and the rotation angle is around 340 °, the air pressure by the air pump 535 is reduced by reducing the output of the air pump 535, and cleaning is performed. The momentum to blow bubbles can be weakened. In this way, the cleaning foam can be discharged uniformly on the inner surface of the toilet.

In addition, the image sensor or the like further includes a dirt detection unit (not shown) that detects the dirt of the toilet 110, and the control unit 130 reciprocates the part where the dirt remains and sprays it intensively. The dirt suppressing effect can be further improved. In addition to the method of partially reciprocating the dirt portion, in the dirt portion, the rotation speed when the discharge port 550u of the spray nozzle 550 passes through may be set to a low speed rotation or the pump output may be increased.

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

In this case, since the user is in a standing posture and the toilet seat 300 is open, the signal of the toilet seat opening / closing detection unit 331 is in the toilet seat open state, and the signal of the seating detection unit 330 is in the non-sitting state.

When the spray switch 417 is pressed by the user, as shown in FIG. 37, the control unit 130 positions the discharge port 550u of the spray nozzle 550 toward the toilet outlet 115 (this embodiment). Then, as shown in the chart of FIG. 37, the spray nozzle driving unit 550a is rotationally driven and stopped until the rotation angle of the discharge port 550u is about 20 °. Thereafter, the water discharge amount variable unit 516 is controlled with a medium output, and the cleaning foam is discharged to the toilet outlet 115 for a predetermined time (in this embodiment, 8 seconds) as shown by the arrow in FIG. The discharged cleaning foam is in a state of covering the water surface above the outlet 115 of the toilet 110, that is, the upper part of the so-called draft surface in the toilet 110 with foam.

In the rotating bubble spraying issuing (foam coating) mode of the control unit 130 described in the section <7> above, the rotating foam spraying the cleaning foam into the toilet while rotating the direction of the discharge port 550u of the spraying nozzle 550. For spraying, in this section <8>, the cleaning foam is sprayed into the toilet 110 while the direction of the discharge port 550u of the spray nozzle 550 is fixed by the fixed foam spraying instruction (splash suppression) mode of the control unit 130. Fixed foam spraying is performed.

As described above, in the state where the user is not seated on the toilet seat 300 and the toilet seat 300 is opened almost vertically as in the case of male urination, the operation unit 210 or the spray switch of the remote controller 400 is used. Assume that a certain manual splash suppression switch 434 is operated. In this case, as shown in FIG. 37, the control unit 130 controls the position where the direction of the discharge port 550u of the spray nozzle 550 is toward the rear of the toilet bowl (in this embodiment, as shown in the chart of FIG. The spray nozzle drive unit 550a is rotationally driven until the rotation angle of the outlet 550u is around 20 °) and stopped. Thereafter, the water discharge amount variable unit 516 is controlled at a high output, and the washing foam is discharged to the rear of the toilet for a predetermined time (8 seconds in the present embodiment) as indicated by an arrow in FIG.

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

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 unit 516 is controlled at a high output, so that the washing bubbles are placed at the upper part of the discharge port 115 in the toilet bowl. The upper surface of the water surface and the waterline in the toilet bowl can be quickly covered with foam. Therefore, it is possible to suppress the odor and the adhesion of dirt near the draft surface of the toilet bowl 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 foam in the direction in which the spray nozzle 550 is fixed and forming bubbles on the upper surface of the water in the toilet 110.

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 of the spray nozzle 550 The spray nozzle driving unit 550a is rotationally driven to a position where the direction of 550u is directed to the toilet outlet 115 and stops. After that, the water discharge amount variable unit 516 is controlled at a high output, and the cleaning foam is discharged toward the back of the toilet. The position where the cleaning foam is fixedly sprayed is the toilet near the outlet 115. Any of the front side, the center, and the rear side may be used.

That is, in a short time of a few seconds after the cleaning foam starts to be discharged, the upper surface of the draft surface and the toilet bowl water line is quickly covered with the foam, so that the urine can be prevented from splashing and scattering, and the draft line in the toilet bowl 110 can be suppressed. The adhesion of dirt in the vicinity and the upper part thereof can be suppressed.

Also, in the fixed foam spraying in which the cleaning foam is sprayed into the toilet bowl 110 while the direction of the discharge port 550u of the spray nozzle 550 is fixed by the fixed foam spraying instruction (strain suppression) mode, in FIG. Is controlled at a high output, and the cleaning foam is discharged toward the outlet 115 of the toilet 110. However, similarly to the rotating foam spraying described in the section <7> above, the output of the water pump 516 that is the water discharge amount variable unit is a constant output that does not change, that is, the water pump that is the water discharge amount variable unit during the fixed foam spraying. The output of 516 may be the same as that at the time of rotating foam spraying.

As described above, the sanitary washing device according to the present embodiment cleans the main body 200 installed in the toilet 110, the washing nozzle 831 for washing the human body, the foam generating unit 560 that produces washing bubbles, and the toilet inner surface. A spray nozzle 550 that discharges water or washing bubbles, a water discharge amount variable unit (water pump 516) that varies the flow rate of cleaning water to be sent to the spray nozzle, and a spray nozzle drive that rotationally drives the direction of the spray nozzle outlet 550u Part 550a. Further, an opening / closing valve 530a for opening and closing a water channel to the spray nozzle 550, a control unit 130 for controlling these operations, and an operation unit 210 (or a remote controller 400) for setting instructions to the control unit 130 are provided.

Then, the control unit 130 rotates the direction of the discharge port 550u of the spray nozzle 550 while rotating the foam in the toilet 110 while rotating the direction of the discharge port 550u, and the discharge port 550u of the spray nozzle 550. It has a fixed foam spraying instruction (splash suppression) mode in which the cleaning foam is sprayed into the toilet bowl while the direction is fixed.

With such a configuration, when the toilet foam is sprayed from the spray nozzle 550 to the toilet bowl 110, the direction of the discharge port 550u of the spray nozzle 550 is rotationally driven and the wash foam is sprayed so as to be widely distributed in the toilet bowl. Thus, a foam film is formed from the front of the toilet bowl to the rear inner face, and the adhesion of dirt on the toilet inner face and in the vicinity of the water line can be suppressed. In addition, with the fixed foam spraying instruction mode in which the cleaning foam is sprayed into the toilet bowl while the direction of the discharge port 550u of the spray nozzle 550 is fixed, the cleaning foam is quickly formed on the upper surface of the water in the toilet bowl 110. The water surface above the discharge port 115 can be covered with cleaning bubbles. Thereby, the unpleasant smell at the time of piss and the scattering by the splash at the time of male piss are suppressed by the washing foam.

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, the foam thickness is about 5 mm, which has the effect of being improved compared to no foam, It can be confirmed that the suppression effect becomes significant when the thickness of the foam is 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 110 by foam dispersion is 5 mm or more and the upper limit is 50 mm or less. In addition, 50 mm or less is an upper limit for making the foam | bubble which accumulated when the user sat down on the toilet seat the foam height which does not stick to a buttocks.

In addition, sanitary washing device 100 according to the present embodiment is installed in main body 200 with spray nozzle 550 inclining rotation axis Ax of discharge port 550u of spray nozzle 550 that is rotationally driven in the front-rear direction and the left-right direction. ing. Further, the inclination in the front-rear direction is configured 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 configured such that the lower side of the rotation axis Ax is inclined toward the cleaning nozzle 831.

Thus, when the toilet nozzle is sprayed from the spray nozzle 550 to the toilet bowl 110, when the discharge port 550u faces the front of the toilet where the distance from the discharge port 550u of the spray nozzle 550 to the spray position is long, the discharge port When the direction of 550u becomes high and the discharge port 550u is directed to the rear of the toilet where the distance from the discharge port 550u of the spray nozzle to the spray position is short, the direction of the discharge port 550u is low.

As described above, along with the distance from the discharge port 550u of the spray nozzle to the inner surface of the toilet 110, the cleaning foam can be sprayed while changing the height of the discharge port 550u of the spray nozzle. Even if the output of the water pump 516 is not changed, 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, in the sanitary washing device 100 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 discharge port 550u of the spray nozzle 550 is discharged. The direction is led from the rear of the toilet to the rear of the toilet through the front of the toilet. Next, the control unit 130 reverses the spray nozzle driving unit 550a so that the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet to the front of the toilet and to the rear of the toilet by at least one reciprocating rotation operation. Execute the process of spraying.

Thereby, at the time of rotating foam spraying spraying the cleaning foam from the spray nozzle 550 to the toilet 110, the control nozzle 130 causes the spray nozzle drive unit 550a to rotate forward so that the direction of the discharge port 550u of the spray nozzle 550 is from the rear of the toilet bowl. It goes to the rear of the toilet through the front of the toilet. Thereafter, the control unit 130 reversely rotates the spray nozzle driving unit 550a so that the direction of the discharge port 550u of the spray nozzle returns from the rear of the toilet to the front of the toilet and back to the rear of the toilet. Then, the output of the water discharge amount variable unit is controlled so that the cleaning foam reaches the vicinity of the rim of the toilet 110. Thereby, washing | cleaning foam can be spread | dispersed to the perimeter of the toilet bowl inner surface, a foam film | membrane can be formed from the toilet bowl front to the back inner surface, and dirt adhesion can be suppressed.

In addition, sanitary washing device 100 according to the present embodiment further includes human body detection sensor 450 that detects entry / exit of a user into / from a toilet room, and controller 130 includes a human body detection sensor 450 that enters the user's room into the toilet room. Is detected, at least by the one reciprocating rotation operation described above, the rotating foam is sprayed on the toilet 110.

Accordingly, when the human body detection sensor 450 detects the user entering the toilet room, the cleaning foam is sprayed on the inner surface of the toilet 110 while the direction of the discharge port 550u of the spray nozzle is driven to rotate at least once. Rotating foam can be sprayed, and before use, a foam film is reliably formed on the inner surface of the toilet bowl, and adhesion of dirt can be suppressed.

Further, in the sanitary washing device 100 of the present embodiment, the control unit 130 opens the on-off valve 530a, so that the washing water is fed by the water discharge amount varying unit 516, and the detergent in the detergent tank 533 is removed from the foam tank. A detergent pump 534 for supplying to 532 and an air pump 535 for supplying air to the foam tank are provided. Then, the cleaning water or the cleaning foam in the foam tank 532 is discharged from the spray nozzle 550.

With such a configuration, not only water or hot water is discharged to the surface of the cleaning nozzle 831 or the inner surface of the toilet bowl, but cleaning bubbles including a detergent are discharged. Thereby, the cleaning effect and the effect which suppresses dirt adhesion can be heightened. In addition, an unpleasant odor can be suppressed and a visually clean and comfortable feeling can be improved by the cleaning foam containing the detergent.

Moreover, in the sanitary washing device 100 of the present embodiment, the control unit 130 has a rinsing instruction mode, and in the rinsing instruction mode, a detergent pump that supplies the detergent in the detergent tank 533 of the foam generation unit 560 to the foam tank 532. In a state where 534 is stopped, the on-off valve 530 a is opened, and the wash water is supplied to the foam tank 532 by the water discharge amount variable unit 516 and discharged from the spray nozzle 550.

With such a configuration, the path from the foam tank 532 to the spray nozzle 550 is rinsed by the washing water, and the clogging due to the fixing of the detergent on the path and the spray nozzle 550 and the rotation failure due to the fixing of the detergent on the spray nozzle 550 are prevented. can do. Moreover, the inner surface of the toilet bowl can be rinsed.

In the present 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 so that it may move.

Further, a spray nozzle 550 for spraying the cleaning foam near the rim of the toilet 110 and a spray nozzle 550 for spraying the cleaning foam near the outlet 115 of the toilet 110 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 rim of the toilet 110 and a discharge port 550u for spraying cleaning foam near the discharge port 115 of the toilet 110.

In the present embodiment, the spray nozzle 550 is configured to spray in the vicinity of the rim of the toilet 110 and in the vicinity of the outlet 115 of the toilet 110, but in the vicinity of the rim of the toilet 110 and the outlet of the toilet 110. In addition to the vicinity of 115, it may be configured to be dispersed at other positions.

Also, as shown in FIGS. 34, 38, and 39, sanitary washing device 100 of the present embodiment is integrally provided with a sleeve case 250 so as to protrude forward from the side of main body 200. . In addition, a sleeve lid 217 provided in front of the operation unit 210 disposed at the upper part of the sleeve case 250, and a foam generating unit 560 at the forefront of the sleeve case 250 inside the sleeve lid 217. A detergent tank 533 that is a transparent or translucent container is built in, and a detergent liquid level confirmation window 216 that can visually confirm the detergent liquid surface position of the detergent tank 533 is provided on the front surface of the sleeve case 250.

With such a configuration, when the user goes in front of the sanitary washing device 100, the remaining amount of the detergent can be easily visually confirmed, so that 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 frontmost part in front of the operation part 210 of the sleeve case 250 and is located closest to the front of the toilet bowl. Therefore, it is possible to make it easy to replenish the detergent. In addition, since the detergent tank 533 having the detergent inlet 537 is installed at the forefront part in front of the operation part 210 of the sleeve case 250, the sleeve cover 217 in front of the operation part 210 is opened, and the detergent 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 height of the detergent inlet 537 is configured to be lower than that of the operation unit 210. Therefore, when the detergent tank 533 is replenished with detergent, more detergent is added. It is possible to prevent the operation unit 210 from falling down.

In the sanitary washing device 100 of the present embodiment, the detergent pump hose 561 shown in FIGS. 6 and 38 guides the detergent from the outlet side of the detergent pump 534 to the inlet side of the foam tank 532 and has a hollow inside. It is a cylindrical tube, and is formed of 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 such a configuration, even if a high pressure from the detergent pump 534 is applied, the detergent pump hose 561 can be prevented from greatly expanding and bursting, and the washing bubbles can be stably removed from the spray nozzle 550. Can be sprayed.

In the sanitary washing device 100 of the present embodiment, the detergent pump hose 561 having a double hose structure is composed of a double hose whose outer side of the elastomer resin tube is covered with a heat shrinkable tube. Not limited to. Even if it is another material, by using a double hose, swelling and bursting can be prevented, and the cleaning foam can be stably sprayed from the spray nozzle 550.

As can be seen from FIGS. 2, 39, and 40, the sanitary washing device 100 according to the present embodiment includes a main body 200 that includes a control unit 130, a spray nozzle 550, a nozzle device 800, and the like. The front surface of the main body case 201 is covered with the 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 outlet 516e of the lower part of the spray nozzle 550 is open | released by the toilet bowl inner surface. (FIG. 40).

Note that FIG. 40 is a cross-sectional view of the center portion of the spray nozzle 550 installed in the rear main body case 201 cut in the front-rear direction in the first embodiment of the present disclosure.

The cleaning foam discharged from the discharge port 516e of the spray nozzle 550 is normally discharged to the inner surface of the toilet as shown by the dotted line T in FIG. However, as in the case of rinsing in the above-described rinsing instruction mode, when cleaning water that does not include detergent and is free of bubbles is discharged from the discharge nozzle 550 through the discharge port 516e, the two-dot chain line S in FIG. As indicated by, the jets may diffuse and scatter, and may splash outside the toilet and wet the floor.

On the other hand, in the sanitary washing device 100 of the present embodiment, as shown in FIG. 40, the body case 202 blocks the upward jet flow from the discharge port 516 e of the spray nozzle 550 with a wall, Scatter guard portions 550z are formed to be dropped into 110. The splash guard 550z can prevent the cleaning bubbles and the cleaning water discharged from the spray nozzle 550 from being ejected outside the toilet 110, and can be sprayed into the toilet 110.

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 cleaning bubbles and the cleaning water discharged from the spray nozzle 550 from being ejected outside the toilet 110.

Also, 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 110. The sanitary washing device 100 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 (FIG. 43). It was removed when the contractor or the user initially installed the toilet 110, and when the user wanted to remove the main body 200 from the toilet 110 and clean the dirt near the bottom of the main body 200. The main body 200 of the sanitary washing device 100 may be temporarily placed on a table or a floor.

As described above, even when the main body 200 of the sanitary washing apparatus is temporarily placed on the base or the floor, the discharge port 516e of the spray nozzle 550 positioned below the mounting surface of the main body 200 is scattered. The guard portion 550z protects the base and the floor from being touched, and damage to the spray nozzle 550 can be prevented. 41, which is a front view of the main body 200, and a two-dot chain line in FIG. 42, which is a side view of the main body 200, indicate 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 100 of the present embodiment, the splash guard part 550z is formed on the main body case 202, but the splash guard part 550z may be formed on the body 550c of the spray nozzle 550 and 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 according to the first embodiment of the present disclosure.

In addition, 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 800, and the like installed therein are omitted for convenience of explanation.

The main body fixing plate 240 is fixed to the toilet 110 through an attachment bolt (not shown) in the position adjusting long hole 241. Then, the main body fixing plate 240 and the center of 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. 200 is fixed to the toilet bowl 110.

Also, when removing the main body 200 from the toilet 110, the main body 200 can be removed by pulling the main body 200 forward while pushing the main body attachment / detachment button 242 next to the main body 200 to the back.

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

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

The control unit 130 is configured not to execute the discharge operation from the spray nozzle 550 when the attachment / detachment sensor 244 detects that the main body 200 is detached from the toilet bowl 110. Thereby, when the main body 200 is removed from the toilet 110, for example, the manual foam coat switch 433 of the remote control main body 401 or the manual splash control switch 434 or the like is pressed. Even if this is done, the discharge operation from the spray nozzle 550 is not executed. For this reason, it is possible to prevent a problem that the washing bubbles are ejected carelessly on the floor and the person.

Further, the control unit 130 is configured not to prohibit the discharge operation from the buttocks cleaning nozzle 831 and the bidet cleaning nozzle 832 even when the attachment / detachment sensor 244 recognizes that the main body 200 is removed from the toilet 110. Yes. Accordingly, even if a failure occurs in the attachment / detachment sensor 244 and a situation in which the main body 200 is mistakenly recognized as being removed from the toilet bowl 110 is a basic function of the sanitary washing device 100, for the user Important buttocks and bidet cleaning can be made feasible.

FIG. 45 is a time chart when rotating foam spraying is performed in the sanitary washing device 100 according to the first embodiment of the present disclosure.

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 produce cleaning foam. The generated cleaning foam is sprayed on the inner surface of the toilet 110 from the discharge port 550u of the spray nozzle 550. 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 which is a stepping motor. In the time chart of FIG. 45, the discharge port 550u of the spray nozzle 550 sprays bubbles while rotating forward from the stop position at the time point N3 to the extreme end position at the time point N6, and then from the extreme end position at the time point N6, Bubbles are sprinkled and returned to the stop position at the time of N9. 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.

In addition, the control part 130 is operating the water pump 516 and the air pump 535 continuously between N3 to N11 sprayed with rotating foam. On the other hand, the detergent pump 534 is intermittently operated such that it rotates normally from N3 to N4, stops, rotates normally from N6 to N7, and stops rotating normally from N9 to N10.

Through experiments, it is more preferable to mix the detergent, water, and air in the intermittent operation than in the continuous operation of the detergent pump 534 during spraying of the rotating foam, and it is possible to generate more stable cleaning bubbles. As described above, stable washing foam can be generated by intermittently operating the detergent pump 534 during spraying of the rotating foam. In addition, wasteful use of the detergent can be prevented, and the trouble of supplying the detergent can be reduced.

In the sanitary washing device 100 of the present embodiment, the detergent pump 534 is operated for 2 seconds in a 6-second cycle in intermittent operation.

In addition, in the time chart when the rotating foam spraying shown in FIG. 45, the chart of the heat exchanger 700 is drawn with a broken line. When the water supplied to the tank 532 is at a temperature lower than 20 ° C., the water is heated by the heat exchanger 700 so that the water temperature is about 20 ° C. and supplied to the foam tank 532. is there. When the water temperature is low, the foaming property is deteriorated. However, by supplying the heat exchanger 700 so that the water temperature is about 20 ° C., it is possible to generate preferable washing bubbles in the foam tank 532.

Also, in the time chart when rotating foam spraying shown in FIG. 45, the detergent pump 534 is inverted from N2 to N3 immediately before the time point N3 when the rotating foam spraying is started. This is because a tube pump is used as the detergent pump 534, and the detergent solution on the outlet side of the tube flows backward to the tube portion that has been crushed by the roller, and the crushed portion becomes cylindrical. This is because a stable amount of detergent can be delivered by normal rotation after recovery.

Also, in the time chart when performing the rotating bubble spraying shown in FIG. 45, from N11 to the time N14 when the rotating foam spraying ends, the spray nozzle driving unit 550a is in contact with the origin position from the stop position. After being driven, the rotation detection microswitch is pressed, and after 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.

As described above, the origin reset operation of the spray nozzle drive unit 550a causes the stepping motor of the spray nozzle drive unit 550a to cause a slip phenomenon due to an increase in some rotational load, and the rotation amount cannot be driven according to 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 a case in which driving cannot be performed. That is, when a signal for pressing the rotation detection microswitch cannot be obtained when spraying the rotating bubbles, the rinsing lamp 223a is turned on to notify the user to perform the rinsing operation by the rinsing switch 223 described above. be able to.

In the sanitary washing device 100 of the present embodiment, the time from the N3 time point when the rotating foam spraying starts to the N12 time point when the rotating foam spraying ends is set to about 15 seconds. This about 15 seconds can be set and changed from the amount of foam accumulated to about 10 seconds, about 25 seconds, etc. according to the size of the toilet 110.

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 rinsing lamp 223a is lit to repeat blinking once with “Chika” and “Chika”. The user is prompted to press the rinse switch 223 to instruct the rinse operation. In the rinsing operation, washing is performed for about 3 minutes while flowing washing water heated to about 40 ° C. in the heat exchanger 700. By this rinsing operation, the foam generating unit 560 and the spray nozzle 550 are rinsed with washing water, and the sticking of the detergent to the foam generating unit 560 and the spray nozzle 550 and clogging are prevented, and stable foam spraying is performed. be able to.

If the detergent or the like becomes hard on the spray nozzle 550 and the movement becomes worse, and the time until the rotation detection micro switch is pressed is delayed by about 20% or more with respect to the set rotation foam spray time, the rinse lamp 223a is set to “Chika, “Chica”, “Chica, Chica” are lit and displayed so as to blink twice, and the rinse switch 223 is pressed to promote the vicinity of the discharge port 550u of the spray nozzle 550 with a toothbrush or the like while performing the rinse operation. It is.

In addition, in the time chart when the rotating foam spraying shown in FIG. 45 is performed, the flow path switching chart is the time from N2 to N3 from the water discharge amount variable unit 516 that is a water pump in the water circuit of FIG. The operation of switching the supply destination of the cleaning water from the nozzle device 800 side to the bubble generating unit 560 side and switching from the bubble generating unit 560 side to the nozzle device 800 side at the time of N11 to N13 is shown.

That is, at the time of N2 to N3, the control unit 130 closes the flow control valve 517 and opens the on-off valve 530a, and at the time of N11 to N13, closes the on-off valve 530a and opens the flow control valve 517. 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.

FIG. 46 is a time chart during the rinsing operation in the sanitary washing device 100 according to the first embodiment of the present disclosure.

When the rinsing switch 223 of the operation unit 210 is pressed and the control unit 130 enters the rinsing instruction 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. The washing water heated to about 40 ° C. by the heat exchanger 700 is kept in the foam tank by the water discharge amount variable unit 516 that is a water pump while the detergent pump 534 is stopped for about 2 minutes from the time N3 to N8. Water is fed to 532 and discharged from the spray nozzle 550.

Further, in addition to the wash water heated to about 40 ° C. for about 1 minute at the time of N8 to N10, the air pump 535 that sends air to the foam tank 532 is rinsed and washed.

In this way, at the time of the rinsing operation for rinsing and washing, first, only the washing water is supplied, and the air pump 535 is operated from the middle to rinse while adding air. As a result, first, most of the detergent components remaining in the foam tank 532 and the flow path are quickly and efficiently discharged from the spray nozzle 550 by the wash water, and then the momentum of the bubbles by the air pump 535 is also added. Since it acts to rinse even a slight residue of the components, it is possible to perform an effective rinse in a short time.

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

FIG. 47 is a time chart when fixed foam spraying is performed in the sanitary washing device 100 according to the first embodiment of the present disclosure.

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. The air pump 535 is operated and the foam tank 532 is supplied with detergent, water, and air to produce cleaning foam.

The generated cleaning foam is sprayed on the inner surface of the toilet 110 from the discharge port 550u of the spray nozzle 550. By collecting bubbles on the water surface of the toilet 110 by spraying fixed bubbles on the inner surface of the toilet, it is possible to suppress flying splashes when men are 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 nozzle drive unit 550a, the spray nozzle drive unit 550a does not rotate the direction of the discharge port 550u and remains fixed when performing fixed bubble spraying. This is the point where fixed bubbles are sprayed. 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) and the stop position is 20 degrees (clockwise). Further, the extreme end position is shown as a position of 340 degrees (clockwise). However, the present disclosure is not limited to this. For example, the origin position is a position of 5 degrees (clockwise from right behind), the stop position is a position of 60 degrees (clockwise from right behind), and the extreme end position is The position may be 300 degrees (clockwise).

47, when an instruction to spray fixed bubbles is issued, the spray nozzle driving unit 550a keeps the direction of the discharge port 550u stopped at a stop position of about 60 degrees clockwise from behind. Immediately sprayed with fixed foam. In this way, if the spray nozzle driving unit 550a is driven and the direction of the discharge port 550u is set to a standby state in advance at a position of about 60 degrees which is the stop position, immediately after the fixed bubble spraying is instructed, The spray nozzle 550 immediately discharges the cleaning foam on the inner surface of the toilet without moving, and quickly forms the necessary foam height on the water surface in the toilet before the male use is started. be able to.

In particular, the direction of the discharge port 550u at the stop position hits the slope of the inner surface of the toilet bowl, and the cleaning foam hitting the slope flows to the position of 50 to 70 (about 60) degrees so as to flow down the water surface so as to rotate on the slope inside the toilet bowl. By doing so, it is possible to quickly form cleaning bubbles on the entire water surface.

In addition, the sanitary washing device 100 of the present embodiment applies the rotating foam spraying described in FIG. 45 not only when the manual foam coat switch 433 of the remote control body 401 is pressed, but also after toilet use, that is, toilet use. Later, it can be set to automatically spray the rotating foam. Furthermore, it can be set so that the rotating bubbles are automatically sprayed at regular intervals. By automatically rotating and lathering after use of the toilet or at regular 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 around the water line in the toilet 110, in particular, ringing.

In the sanitary washing device 100 according to the present embodiment, when the automatic operation setting for spraying the rotating foam after use of the toilet is set, when the user stands up from the toilet seat 300, the seating sensor 330 detects it, and after about 60 seconds, Rotating foam is applied for about 15 seconds. When male toilet is not seated on the toilet seat, when the toilet seat 300 is closed, it is detected by the toilet seat opening / closing sensor 331, and after about 60 seconds, rotating foam is sprayed for about 15 seconds.

In addition, about 60 seconds mentioned above is a structure which can be set and changed about 10 seconds after 25 seconds etc. with the switch of the remote control main body 401. FIG. Thus, the time from when the user stands up from the toilet seat until the start of rotating foam spraying can be adjusted to a time that suits the user's usage.

Moreover, about 15 seconds of the rotating bubble spraying time can be changed to 10 seconds, 25 seconds, or the like by a switch of the remote control body 401. Thereby, according to the magnitude | size of the toilet bowl 110, the quantity of the foam to accumulate can be adjusted.

In addition, the sanitary washing device 100 according to the present embodiment applies the fixed foam spraying described in FIG. 47 not only when the manual splash suppression switch 434 of the remote control main body 401 is pressed but also when the toilet seat 300 is opened. It can be set to automatically spray fixed bubbles. When the toilet seat 300 is opened at the time of male use, it is possible to suppress splashing at the time of male use by adopting a configuration in which fixed bubbles are automatically sprayed.

In the sanitary washing device 100 according to the present embodiment, when the toilet seat 300 is opened and the automatic operation setting for spraying fixed bubbles is performed, the toilet seat 300 is opened immediately after the toilet seat 300 is opened. A fixed foam spray is applied for 15 seconds.

In addition, about 15 seconds of the above-described fixed bubble spraying time can be changed to 10 seconds, 25 seconds, or the like by a switch on the remote control main body 401. Thereby, according to the magnitude | size of the toilet bowl 110, the quantity of the foam to accumulate can be adjusted.

FIG. 48 is a diagram illustrating a configuration for selecting and setting automatic operation of fixed foam spraying and rotating foam spraying according to the first embodiment of the present disclosure.

Every time the automatic selection setting switch 236 of the operation unit 210 is pressed, a desired setting can be selected. Next to the automatic selection setting switch 236, an automatic rotating spray lamp 236a after use, an automatic rotating spray lamp 236b after every fixed time, and an automatic fixed foam spraying display lamp 236c when the toilet seat is opened are arranged. Each time the setting switch 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. "Is shown. From this state, when the automatic selection setting switch 236 is pressed once, only the automatic rotation spray lamp 236a after use is turned on.

Thus, every time the automatic selection setting switch 236 is pressed, the setting can be shifted to H2, H3... H6, and in H7, all of the three types of automatic driving can be in the “ON” state. It is. In the lamp display of FIG. 48, a circle indicates that the lamp is turned off and indicates a setting “off” state, and a circle indicates that the lamp is turned on and indicates a setting “on” state.

For example, in FIG. 48, in the case of H2, H4, H6, and H7 which are settings for performing automatic operation of rotating foam spraying at regular intervals, the rotating foam spraying shown in the time chart of FIG. It is executed every hour and can suppress dirt around the water line in the toilet 110, in particular, ringing.

The above-mentioned about 3 hours can be set and changed every 6 hours, every 12 hours, every 24 hours, etc. with the switch of the remote control body 401. It can be adjusted according to the convenience of the user, such as reducing the number of times.

(Second Embodiment)
FIG. 51 is a perspective view of a sanitary washing device 1000 according to the second embodiment of the present disclosure.
