In addition, the washing water supply flow path 690 is finally connected to the nozzle device 800.

The water supply connection port 510 is arranged at the lower right side of the main body 200 and is connected to, for example, an external water pipe line. The strainer 511 is arranged inside the water supply connection port 510 to prevent the inflow of sand and soil contained in the tap water. The check valve 512 prevents the water stored in the auxiliary water tank 600 from flowing back to the water pipe line.

The constant flow valve 513 is arranged downstream of the check valve 512 to keep the amount of washing water flowing to the washing water supply flow path 690 constant. The water stop solenoid valve 514 electrically opens and closes the washing water supply flow path 690 according to a signal from the control unit 130. As shown in FIG. 7, the constant flow valve 513, the water stop solenoid valve 514, and the relief valve 515 are integrally comprised.

The sub-tank 600 is arranged downstream of the water stop solenoid valve 514 and is provided with an air opening 603. The heat exchanger 700 can instantly heat the washing water to a set temperature. The buffer tank 750 will make the temperature of the warm water heated by the heat exchanger 700 uniform.

The water pump 516 constituting the variable part of the spouting water volume is connected to the downstream of the buffer tank 750. The nozzle device 800 is arranged downstream of the water pump 516 and connected to the water pump 516 through the fluid regulating valve 517. Each port of the fluid regulating valve 517 is connected to the buttocks washing nozzle 831, the female washing nozzle 832, and the nozzle cleaning part 833 of the nozzle device 800.

Moreover, as shown in FIG. 6, the branch flow path 530 is equipped with the on-off valve 530a, and it is branched and arrange|positioned between the water pump 516 and the fluid regulating valve 517 of the washing water supply flow path 690. The branch flow path 530 connects the washing water supply flow path 690 and the foam generating part 560.

The foam generating part 560 is composed of a check valve 531, a foam tank 532, a lotion tank 533, a lotion pump 534, an air pump 535, and the like.

The branch flow path 530 is a foam tank 532 that supplies washing water to the foam generating part 560 through the check valve 531.

The spreading nozzle 550 is connected to the downstream of the foam tank 532 and is rotationally driven by the spreading nozzle driving part 550a. The lotion tank 533 and the lotion pump 534 are connected to the foam tank 532 and supply lotion to the foam tank 532.

Check valve 531b (Duckbill). That is, in the present embodiment, the structure is provided with a plurality of check valves on the upstream side of the water entering the foam tank 532. Thereby, the reverse flow prevention structure with a double structure prevents the liquid or washing foam in the foam tank 532 containing the lotion from flowing back to the tap water side, thereby improving safety.

In addition, the dotted line shown in FIG. 6 shows that the control unit 130 is electrically connected to each component, and is controlled by the control unit 130. ＜3＞The discharge control, function and action on the inner surface of the toilet by the spreading nozzle

Hereinafter, the discharge control to the inner surface of the toilet by the spreading nozzle of the sanitary washing device and its function and operation will be described with reference to FIGS. 7 to 12.

Fig. 7 is a perspective view showing the appearance of the spray nozzle of the sanitary washing device. Fig. 8 is a longitudinal sectional view of the dispersion nozzle. Fig. 8 is a longitudinal cross-sectional view showing the installation state of the spreading nozzles in the sanitary washing device. Fig. 10 is a front view showing the installation state of the spreading nozzles in the sanitary washing device. Fig. 11 is a plan view showing the installation position of the dispersion nozzle and the rotation angle of the discharge port of the dispersion nozzle in the sanitary washing device. Fig. 12 is a graph showing the output of the discharge water amount variable unit in the rotation angle of the discharge port of the dispersion nozzle.

As shown in FIGS. 7 and 8, the dispersion nozzle 550 is composed of a dispersion nozzle drive portion 550a, a main body 550c, a rotating nozzle 550d, and the like. The dispersing nozzle driving unit 550a is constituted by, for example, a motor, and rotationally drives the rotating nozzle 550d. The main body 550c has an inlet flow path 550b and an inlet hole 550h, and supplies washing foam, washing water, etc., generated by the foam generating unit 560 shown in FIG. 6 to the rotating nozzle 550d. In addition, the main body 550c rotatably holds the rotating nozzle 550d shaft-sealed with an O-ring 550e and an O-ring 550f inside. Furthermore, an X-shaped ring may be used instead of the above-mentioned O-ring 550f. Thereby, the torque required for the rotational driving of the rotating nozzle 550d can be reduced. In addition, it is possible to more reliably prevent the rotation nozzle 550d from sticking. As a result, it becomes possible to use a small, low-torque motor for the dispersion nozzle drive part 550a.

In addition, the rotating nozzle 550d is rotatably driven by fitting with the spreading nozzle driving part 550a through the shaft 550n.

As described above, the spray nozzle 550 of the present embodiment can be constructed and operate as follows.

First, the washing water or washing foam generated in the foam generating part 560 shown in FIG. 6 is supplied from the inlet flow path 550b of the main body 550c of the spray nozzle 550. The supplied washing water or washing foam is supplied into the rotating nozzle 550d from a plurality of inlet holes 550h cut around the rotating nozzle 550d. After that, the supplied washing water or washing foam is discharged from the discharge port 550u of the rotating nozzle 550d toward the inner surface of the toilet 110 or the buttocks washing nozzle 831.

As shown in FIGS. 10 and 11, the spreading nozzle 550 is arranged on the right side of the center of the main body 200. The reason is that the washing nozzle (that is, buttocks washing nozzle 831, etc.) for washing the human body part is preferentially arranged in the center. Therefore, the dispersion nozzle 550 is not arranged in the center, but arranged on either side of the left or right. Furthermore, of course, the above configuration can also be reversed.

Next, the discharge control of the dispersion nozzle 550 will be described with reference to FIG. 6.

In addition, in the following content, the discharge control in the rotating foam dispersing command issuing mode of the dispersing nozzle 550 when the user is not in a seated state and the toilet seat is in a closed state will be described.

First, when the user enters the toilet, the control unit 130 of the sanitary washing device 100 uses the human body detection sensor 450 to detect the person entering the room. At this time, the control unit 130 is set to a rotating foam dispersing command issuance (foam application) mode, which rotates the direction of the discharge port 550u of the dispersing nozzle 550 and disperses the cleansing foam in the toilet. Thereby, the control unit 130 enters into the toilet 110 to perform the action of spreading the rotating foam. In addition, the control unit 130 will start the operation of the water pump 516 shown in FIG. 6. In addition, the control unit 130 opens the on-off valve 530a of the branch flow path 530.

In this case, the fluid regulating valve 517 for switching the flow path of the buttocks washing nozzle 831, the female part washing nozzle 832, the nozzle cleaning part 833, etc. is in the closed state. Therefore, the washing water from the heat exchanger 700 passes through the branch flow path 530 and the check valve 531 and the foam tank 532 constituting the foam generating part 560 and is supplied to the spray nozzle 550. The supplied washing water is discharged from the discharge port 550u of the dispersion nozzle 550 toward the inner surface of the toilet or the buttocks washing nozzle 831.

That is, the control unit 130 drives the spreading nozzle driving unit 550a of the spreading nozzle 550 to rotate the discharge port 550u of the rotating nozzle 550d. At this time, the washing water or washing foam discharged from the discharge port 550u will spread on the inner surface of the toilet 110 or the buttocks washing nozzle 831, etc., to form a water film or a foam film. Thereby, the adhesion of dirt and the like to the inner surface of the toilet can be prevented in advance.

Furthermore, as shown in FIG. 11, the distance from the discharge port 550u of the dispersion nozzle 550 to the inner surface of the toilet varies according to the direction of the rotation angle of the dispersion nozzle 550.

That is, when the rotation angle of the dispersion nozzle 550 arranged at the above-mentioned position is changed, as shown in FIG. The distance to the inner surface will become the longest (far). On the other hand, when the rotation angle of the discharge port 550u is 340° (corresponding to the position rotated by 180° from the above-mentioned 160°), the distance from the discharge port 550u to the inner surface of the toilet becomes the shortest (close).

Therefore, as shown in FIG. 12, the control unit 130 controls the rotation angle (distance) of the discharge port 550u of the dispersion nozzle 550 to change the output of the water pump 516 constituting the discharge water variable unit.

Hereinafter, the method of controlling the output of the water pump 516 according to the rotation angle of the dispersion nozzle 550 will be described.

First, the control unit 130 starts the above-mentioned control when the human body detection sensor 450 detects that the user enters the toilet.

At this time, the control unit 130 is in the form shown in FIG. 12, in accordance with the rotation angle of the discharge port 550u of the dispersion nozzle 550, while changing the output of the water pump 516 in the range from "high" to "low", it discharges the wash Net foam and so on.

Specifically, in the vicinity of the rotation angle of 160° where the distance to the inner surface of the toilet is the longest (far) as shown in Fig. 11, the control unit 130 will set the output of the water pump 516 to be larger as shown in Fig. 12 . On the other hand, in the vicinity of the rotation angle of 340° where the distance to the inner surface of the toilet is the shortest (near), the control unit 130 sets the output of the water pump 516 to be small.

More specifically, the control unit 130 changes the output of the water pump 516 from "low" to "low" in a stepwise or continuous manner as shown in FIG. 12 within the range of the rotation angle of 0° to 160°. middle". Similarly, the control unit 130 changes the output of the water pump 516 from "medium" to "low" stepwise or continuously within the range of the rotation angle of 160° to 340°. Thereby, according to the distance from the discharge port 550u to the inner surface of the toilet, the washing water or washing foam is spread to a predetermined height range over the entire circumference of the inner surface of the toilet.

In addition, in FIG. 12, the operation|movement of the dispersion nozzle 550 provided with the rotation restriction part mentioned later is shown as an example. Therefore, it is displayed as a graph of the output change of the water pump 516 within the range of the rotation angle of 0° to 340°. However, in the case of a configuration that does not provide a rotation restricting portion, of course, the output of the water pump 516 may be changed within the range of the rotation angle covering one rotation from 0° to 360°.

That is, the control unit 130 controls the spray volume (and spray speed) of the washing water or foam from the spray nozzle 550 in accordance with the rotation angle of the spray nozzle 550 (that is, the distance between the discharge port 550u and the inner surface of the toilet). ).

More specifically, when spitting clean foam and clean water to the front of the toilet which is the furthest distance from the spray outlet 550u of the dispersing nozzle 550, the output of the water pump 516 is set to "medium" and the output is stronger. The force of spit out washing foam and washing water. Thereby, the washing foam and washing water can be fully delivered to the inner surface of the front of the toilet.

On the other hand, when spitting clean foam or cleansing water to the back of the toilet which is the closest distance to the outlet 550u of the spray nozzle 550, set the output of the water pump 516 to "low" and spit it out with the weakest force Wash foam or wash water. In this way, it is possible to prevent the occurrence of undesirable conditions such as washing foam or washing water rebound.

Furthermore, before use, washing water or washing foam is discharged to the entire inner surface of the toilet to form a water film or foam film. As a result, it is possible to suppress the adhesion of dirt to the inner surface of the toilet when it is in use.

Furthermore, in this embodiment, when the human body detection sensor 450 detects that the user enters the toilet, or when the user operates the spreading switch 417 through the operation unit 210 or the remote controller 400, the control unit 130 will Before use, perform the so-called toilet foam dispersion, which is to spread the washing foam on the inner surface of the toilet in advance.

At this time, the control unit 130 is based on the above-mentioned toilet foam distribution signal. When performing toilet foam distribution, as shown in FIG. Scattered cleaning foam on the surface. Specifically, the control unit 130 first rotates the dispersion nozzle driving unit 550a forward (for example, in a clockwise direction), and moves the discharge port 550u of the rotating nozzle 550d from the back of the toilet, through the front of the toilet, and then to the back of the toilet. Spread washing foam on one side. In addition, the control unit 130 then reverses the spreading nozzle driving unit 550a (for example, counterclockwise), and spreads while moving the direction of the discharge port 550u of the rotating nozzle 550d in the direction from the back of the toilet, through the front of the toilet, and then back to the back of the toilet. Wash off the foam. That is, the following steps are performed: covering the inner circumferential surface of the toilet, rotating the discharge port 550u of the rotating nozzle 550d in the forward and reverse directions, and dispersing the washing foam by rotating at least once back and forth.

At this time, the control unit 130 controls the output of the discharge water amount variable unit so that the washing foam reaches the vicinity of the edge 110a of the toilet 110. Thereby, the cleansing foam can be spread on almost the entire circumference (including the entire circumference) of the inner surface of the toilet before use. As a result, a foam film can be formed on the inner surface from the front to the back of the toilet, and the adhesion of dirt can be suppressed when it does not occur.

In this case, as shown in FIG. 12, the control unit 130 should preferably control the output of the spouting amount variable unit during the forward rotation of the dispersion nozzle drive unit 550a to be lower than the output during the reverse rotation of the dispersion nozzle drive unit 550a. Come and spit out the cleansing foam.

As long as the output of the variable part of the spray water volume is reduced, the force of spraying the washing foam will be weakened, so the washing foam can be spread to a close place (position) by the spray nozzle. Specifically, as shown by the spreading movement trajectory TF shown by the dotted line in FIG. 11, when rotating forward (clockwise), the direction of the outlet 550u of the rotating nozzle 550d will be closer to the edge 110a of the toilet 110 Spread the cleansing foam on the inner side of the draft surface 110b.

On the other hand, as long as the output of the variable part of the spouting water volume is increased, the force to spout the washing foam will be increased, so the washing foam can be spread farther (position) by the spray nozzle. Specifically, as shown by the spreading movement trajectory TR shown by the dotted line in FIG. 11, when rotating in the reverse direction (counterclockwise), the direction of the discharge port 550u of the rotating nozzle 550d is directed closer to the edge 110a of the toilet 110 Spread the cleansing foam on the side.

In this way, in the initial stage of the start of spreading (in the normal rotation), firstly, the water surface 110b above the discharge port 115 of the toilet 110 can be covered with a cleansing foam. After that, when reversed, the cleansing foam can be spread on almost the entire circumference of the inner surface of the toilet 110 near the edge 110a. As a result, a foam film is formed on the draft surface 110b from the front to the rear of the toilet and the inner surface from the draft surface 110b to the edge 110a, and the adhesion of dirt can be effectively suppressed.

Moreover, in this embodiment, as shown in FIGS. 2, 9, 10, 11, etc., the dispersion nozzle 550 is arranged at a position in front of the main body 200 installed on the toilet 110. That is, the spreading nozzle 550 is installed on the front side than the front end position in the state in which the nozzle device 800 is stored, wherein the nozzle device 800 is made to protrude from the storage position of the washing nozzle 831 to the buttocks washing or the vagina washing. It is a device for washing the human body. Thereby, when rotating and driving, the direction of the discharge port 550u of the rotating nozzle 550d can be directed to the back of the toilet 110, so that the washing foam can be foamed. As a result, a foam film of cleansing foam can be formed on the inner surface of the front to the rear of the toilet 110, and the adhesion of dirt can be suppressed.

In addition, in the above description, although the configuration is controlled to change the output of the water pump 516 that constitutes the variable part of the spouting water amount when the rotating foam is dispersed in the toilet, the description is taken as an example. It is not limited to this. For example, when rotating foam is sprayed, the output of the water pump 516 is not changed, and the spray nozzle 550 may be configured as described below to form a foam film on the inner surface from the front to the back of the toilet to suppress the adhesion of dirt. .

At this time, as shown in FIGS. 9 and 10, the rotation axis Ax of the dispersion nozzle 550 is inclined in the front-rear direction and the left-right direction and is installed in the main body 200. Specifically, the rotation axis Ax of the dispersion nozzle 550 is arranged in the front-rear direction so that the dispersion nozzle 550 faces the downward side and is inclined toward the front side of the toilet 110. In addition, the rotation axis Ax of the dispersion nozzle 550 is arranged so that the dispersion nozzle 550 faces downward in the left-right direction and is inclined toward the washing nozzle 831 arranged in the center of the main body 200. With the arrangement and configuration of the rotation axis Ax described above, when the discharge port 550u of the dispersion nozzle 550 is facing forward of the toilet 110 whose distance to the dispersion position becomes greater, the position of the discharge port 550u becomes higher. Therefore, as shown in the discharge port direction AcA in FIG. 9, washing foam can be discharged in the horizontal direction. As a result, the cleansing foam can be spread to the vicinity of the edge 110a in front of the toilet 110.

On the other hand, when the discharge port 550u of the spreading nozzle 550 faces the back of the toilet 110 whose distance to the spreading position becomes shorter, the position of the discharge port 550u becomes lower. Therefore, as shown in the discharge port direction AcB in FIG. 9, the cleansing foam can be discharged in the obliquely downward direction.

In addition, when the distance to the spreading position is on the right side of the toilet 110, which is gradually increasing, and the discharge port 550u advances from the back to the front, the direction of the discharge port 550u is gradually changed from the discharge port direction AcB to the discharge port direction AcA. The ground becomes higher. As a result, the cleansing foam can be spread along the vicinity of the edge 110a on the right side of the toilet bowl 110. In addition, when the distance to the spreading position is on the left side of the toilet 110 that is gradually getting closer and the discharge port 550u advances from the front to the rear, the direction of the discharge port 550u is changed from the discharge port direction AcA to the discharge port direction AcB. And gradually become lower.

That is, when the rotating foam is spreading, the spreading nozzle driving section 550a is driven to be rotated around the rotation axis Ax to spread in the following direction: the direction of the discharge port 550u of the rotating nozzle 550d is, for example, from the discharge port direction AcB to the via The direction of the discharge port is AcA and the direction of the discharge port AcB. At this time, as described above, as the dispersion nozzle 550 rotates, the distance from the discharge port 550u to the inner surface of the toilet 110 changes. However, by inclining the rotation axis Ax of the dispersion nozzle 550, it is possible to spread the wash while changing the height position of the discharge port 550u of the dispersion nozzle 550 as shown in the discharge port direction AcA and the discharge port direction AcB as shown in the discharge port direction AcB. Net bubble. Therefore, it is possible to form a foam film on the inner surface near the edge 110a from the front to the back of the toilet 110 along the spreading movement track TR shown by the left-handed dashed arrow in FIG. 11. As a result, the entire inner surface from the front to the rear of the toilet 110 can be covered, and the adhesion of dirt can be suppressed.

According to the above configuration, when the rotating foam is spread, the output of the water pump 516 is not changed, and the washing foam can be discharged with a fixed output. Therefore, when the right-handed rotating foam is spreading, the same trajectory as the spreading movement trajectory TR shown by the left-handed dashed arrow shown in FIG. 11 can be used to advance in the opposite direction and spread the washing foam.

Furthermore, in this embodiment, the rotation axis Ax of the dispersion nozzle 550 is such that the inclination angle β in the front and rear directions shown in FIG. 9 is, for example, 20 degrees, and the inclination angle in the left and right directions shown in FIG. γ is arranged at 10 degrees, for example. Of course, the above-mentioned angle can be arbitrarily changed according to the shape of the toilet or the arrangement position of the spray nozzle 550.

In addition, the height position of the discharge port 550u of the dispersion nozzle 550 is set to be lower than the upper end surface 110c of the toilet 110 regardless of the rotation position.

In addition, in the above description, although the forward rotation is a right-handed rotation when viewed from above in FIG. 11, the reverse rotation is a left-handed rotation, but it is not limited to this. For example, the forward rotation may be a left-handed rotation, and the reverse rotation may be a right-handed rotation. That is, it is described that the direction in which the discharge port 550u of the dispersion nozzle starts to rotate at the time of dispersion is referred to as forward rotation, and the direction of return is referred to as reverse rotation, and the direction of rotation is not particularly limited.

As described above, the control unit 130 changes the output of the water pump 516 according to the rotation angle of the discharge port 550u of the dispersion nozzle 550. Thereby, the washing water or washing foam can be discharged from the front, the side, and the rear of the inner surface of the toilet 110 with different distances from the spray nozzle 550 so as to be surely delivered. As a result, a water film or a foam film can be formed in a wide range of the inner surface of the toilet 110 to suppress the adhesion of dirt.

Furthermore, in the above-mentioned embodiment, the description is made using the configuration of setting "high" and "low" based on the average level "medium" of the output of the water pump 516 as an example, but it is not limited to this. . For example, it may be configured to set the average level "medium" of the output of the water pump 516 to be higher or lower to change the reference level. At this time, it is desirable to provide a level switch for adjusting the average level on the operating unit 210 or the remote controller 400. Thereby, even when the size of the toilet 110 in which the sanitary washing device 100 is installed is different, the washing water or washing foam can be discharged to the entire circumference of the inner surface of the toilet. In addition, it may be configured such that the height position (relative to the horizontal plane) of the cleansing foam scattered on the inner surface of the toilet 110 can be arbitrarily changed. Thereby, it is possible to form a water film or a foam film on any position on the inner surface of the toilet bowl 110, and it is possible to suppress the adhesion of dirt.

In addition, in the above-mentioned embodiment, although the control unit 130 is described as an example of the discharge control in which the output of the water pump 516 is changed in accordance with the rotation angle of the discharge port 550u of the dispersion nozzle 550, it is not limited to this. . For example, in addition to the change of the output of the water pump 516, the control unit 130 may also control the rotation speed of the dispersion nozzle driving unit 550a to change in accordance with the rotation angle of the discharge port 550u.

That is, in this embodiment, the output of the water pump 516 is changed, and the discharge force of the washing water or washing foam is changed. In this way, the washing water or washing foam is surely spread to the inner surface of the farther toilet 110, and the rebound on the inner surface of the closer toilet 110 is effectively suppressed.

However, when the discharge port 550u of the spreading nozzle 550 is rotated at a fixed rotation speed, the spreading density of the washing foam and washing water becomes sparser when the distance to the inner surface of the toilet is longer. On the other hand, where the distance to the inner surface of the toilet is relatively close, the dispersion density of the washing foam and washing water will become denser.

Therefore, in this embodiment, in accordance with the rotation angle of the discharge port 550u, the dispersion nozzle driving section 550a may be used to change the rotation speed of the dispersion nozzle 550. In this way, the entire circumference of the inner surface of the toilet 110 can be covered to spread the washing water or the washing foam with an even distribution density.

Furthermore, even when the output of the water pump 516 is changed to spread the washing foam and washing water, the spreading density of the washing foam and washing water can be made equal to a certain extent.

However, when the rotation speed of the dispersion nozzle driving part 550a is changed in accordance with the rotation angle of the dispersion nozzle 550 to spread the washing foam and washing water, the dispersion density can be made more uniform. In other words, the entire circumference of the inner surface of the toilet 110 can be covered to spread the washing water or the washing foam with a more even distribution density.

That is, when the rotation speed is fixed, as shown in FIG. 11, the washing water or washing is scattered around 160° (even in front of the device 110) at the rotation angle that is the furthest distance from the discharge port 550u of the dispersion nozzle 550 The net foam will disperse and the dispersion density will become thinner. Therefore, when the washing foam and washing water are discharged to the front of the toilet 110, the rotation speed of the dispersing nozzle 550 is set to the slowest. Thereby, the time for the discharge port 550u of the dispersion nozzle 550 to pass through the vicinity of the front of the toilet 110 becomes longer. As a result, the dispersion density of the washing foam can be increased.

On the other hand, when the rotation speed is fixed, the washing foam or washing water discharged from the rotation angle of 340°, which is the closest distance to the discharge port 550u of the dispersing nozzle 550 (even after the device 110), will gather. And make the dispersion density denser. Therefore, the rotation speed of the dispersion nozzle 550 is set to be the fastest. Thereby, the time for the discharge port 550u of the dispersion nozzle 550 to pass through the vicinity of the back of the toilet is shortened. As a result, the dispersion density of the washing foam can be reduced.

That is, by the variable rotation speed, the distribution of the washing water or the washing foam scattered on the inner surface of the toilet can be formed evenly (eliminating shades). Therefore, with no uneven foam film formation, the entire circumference of the inner surface of the toilet can be covered, and the adhesion of dirt can be more effectively suppressed.

As described above, the control unit 130 changes the rotation speed of the dispersion nozzle driving unit 550a in accordance with the rotation angle of the discharge port 550u of the dispersion nozzle 550. For example, when the direction of the discharge port 550u of the dispersion nozzle 550 is a rotation angle toward the front of the toilet where the distance to the inner surface of the toilet is longer, the rotation speed of the dispersion nozzle drive part 550a is set to gradually decrease (lower speed) . On the other hand, when the direction of the discharge port 550u is a rotation angle toward the back of the toilet where the distance to the inner surface of the toilet is short, the speed of the spreading nozzle driving part is set to gradually increase (higher speed). Thereby, the washing water or washing foam can be spit out evenly when there is no unevenness of spreading density to the front, the side, or the back of the toilet at different distances. As a result, the adhesion of dirt can be effectively suppressed by the evenly formed water film or foam film on the inner surface of the toilet.

In addition, in this embodiment, the control unit 130 controls such that when the human body detection sensor 450 detects the entry of a person, it executes the spraying of washing water or washing foam onto the inner surface of the toilet from the spraying nozzle 550 in advance. So-called toilet foam is scattered. Specifically, the control unit 130 controls the spray nozzle drive unit 550a to rotate and drive the rotating nozzle 550d at least once, for example, to automatically stop after foaming. Thereby, before the user uses the sanitary washing device, a water film or a foam film can be formed on the inner surface of the toilet in advance. As a result, it is possible to effectively suppress the adhesion of dirt on the inner surface of the toilet during use.

In addition, in the above description, the spray nozzle 550 is rotated once to and fro to spray the washing foam or washing water before use, but it is not limited to this. For example, as long as it is the number of times that the dispersed washing foam and washing water can sufficiently spread over the inner surface of the toilet bowl, the number of times may be arbitrary. In this case, the number of rounds when the toilet foam is dispersed is preferably configured to be selectable and set by the user through the operating unit 210 or the remote controller 400.

In addition, in the above-mentioned embodiment, the rotation direction of the dispersion nozzle 550 is not particularly mentioned. As shown in FIG. 12, the rotating nozzle 550d is configured to rotate once back and forth. The reason is that when the rotating nozzle 550d of the spray nozzle 550 is configured to rotate only in either the right direction or the left direction, the spray direction of the washing water or washing foam will be constant. The ground becomes the same direction. Therefore, in the present embodiment, the washing foam or washing water is spread on the inner surface of the toilet from the two directions of forward and reverse rotation by one round of rotation. Thereby, it is possible to further reduce the occurrence of so-called scattered omissions. Therefore, it becomes possible to spread the washing foam or washing water more evenly on the inner surface of the toilet. As a result, the adhesion of dirt to the inner surface of the toilet can be suppressed with a small number of times (time) of spreading. In addition, the above-mentioned back-and-forth rotation is not limited to one back-and-forth, and it may be set to multiple back-and-forths such as two back-and-forths or three back-and-forths.

Specifically, as shown in FIG. 12, first, the rotating nozzle 550d of the dispersion nozzle 550 is rotated forward (for example, clockwise) from a rotation angle of 0° on the rear side of the toilet 110 to a rotation angle of 340°. stop for a while. After that, the rotating nozzle 550d is reversely rotated (for example, counterclockwise) from a rotation angle of 340° to a rotation angle of 0°, and is stopped after one back-and-forth rotation.

In this case, it is desirable to provide a mechanical stopper (ie, a rotation restricting portion) that limits the rotatable range of the rotating nozzle 550d of the spreading nozzle 550 to the range of a rotation angle of 0° to a rotation angle of 340°. (Not shown) structure.

Specifically, the rotation restricting portion is constituted by, for example, a protrusion formed on a part of the outer circumference of the rotating nozzle 550d and a rotation restricting wall of the main body 550c. With this configuration, when the protrusion rotates and physically abuts against the rotation restricting wall, the movement of the rotating nozzle 550d to be rotated is restricted. That is, the motor constituting the dispersion nozzle driving portion 550a slips and idly rotates by abutting. Thereby, the rotating nozzle 550d can restrict the rotation above the rotatable range.

As described above, the spreading nozzle 550 configured as described above is provided with a rotation restricting portion for restricting the rotation range, and the spreading nozzle 550 can be rotated back and forth within the rotatable range that is not restricted by the rotation restricting portion. In addition, the washing foam or washing water is spread on the inner surface of the toilet from two directions of forward and reverse rotation performed by the back and forth rotation. This reduces the occurrence of so-called scattered omissions. Therefore, it becomes possible to spread the washing foam and washing water more evenly on the inner surface of the toilet. As a result, it is possible to use a small number of spreads (time) to form a foam film that can suppress the adhesion of dirt to the inner surface of the toilet.

In addition, the control unit 130 may always recognize the position where the protrusion of the rotating nozzle 550d of the dispersion nozzle 550 configured as described above and the rotation restricting portion abuts as the origin of the rotation position of the dispersion nozzle driving portion 550a. Therefore, it is possible to prevent the origin shift caused by the back and forth movement of the rotating nozzle 550d. Thereby, the position accuracy of the rotation angle of the rotating nozzle 550d with respect to the inner surface of the toilet can be improved. That is, relative to the predetermined position of the inner surface of the toilet, deviations such as positional deviation can be reduced. As a result, it is possible to disperse the washing foam and washing water from the discharge port 550u of the dispersing nozzle 550 at the correct position on the inner surface of the toilet with an appropriate discharge output and rotation speed.

Furthermore, in the above description, although the configuration that physically restricts the rotation range of the dispersion nozzle 550 is described as an example, it is not limited to this. In the case where the positional deviation of the origin of the dispersion nozzle 550 does not constitute a problem, the dispersion nozzle driving unit 550a may simply perform the forward and reverse rotation operation of the dispersion nozzle 550. Thereby, the rotation restricting part becomes unnecessary, and various operations of the rotating nozzle 550d, such as forward and reverse rotation or unidirectional rotation, can be performed. As a result, the rotating nozzle 550d can be operated more appropriately in accordance with the condition such as dirt on the inner surface of the toilet. In this case, it is preferable to set the origin of the spreading nozzle 550 to a portion adjacent to the 160° rotation angle to be reversed, and to control the rotation speed to gradually slow down at the adjacent portion. Thereby, the load applied when the dispersion nozzle drive part 550a is reversed rapidly can be reduced.

Hereinafter, the structure of the foam generating unit 560 of the sanitary washing device of this embodiment will be described with reference to FIG. 6.

As shown in FIG. 6, the bubble generating part 560 is connected to the branch flow path 530 through the on-off valve 530a and the check valve 531. The flow path between the washing water supply flow path 690 is branched. Furthermore, by opening and closing the on-off valve 530a, the washing water is supplied to the bubble generating part 560 through the branch flow path 530.

The foam generating part 560 is composed of a check valve 531, a foam tank 532, a lotion tank 533, a lotion pump 534, an air pump 535, and the like.

A spray nozzle 550 is connected downstream of the foam tank 532. The foam tank 532 is connected to the lotion tank 533 for supplying lotion through the lotion pump 534.

The foam box 532 is also connected with an air pump 535. The air pump 535 sends air into the foam box 532 to generate washing foam or the like. In addition, the air pump 535 supplies the washing water and the generated washing foam to the dispersion nozzle 550.

As described above, the foam generating unit 560 can be configured and operate as follows.

First, the control unit 130 opens the on-off valve 530a. Then, the control unit 130 drives the water pump 516, and the heat exchanger 700 sends the washing water to the foam tank 532 of the foam generating unit 560. At this time, the lotion supplied from the lotion tank 533 by the lotion pump 534 and the washing water supplied from the heat exchanger 700 are mixed in the foam tank 532.

Secondly, the control unit 130 drives the air pump 535 to supply air into the foam tank 532. Thereby, washing foam is generated in the foam tank 532. The generated cleansing foam is supplied to the spreading nozzle 550, and is discharged to the inner surface of the toilet from the discharge port 550u of the rotating nozzle 550d.

At this time, in accordance with the increase or decrease of the output of the water pump 516 and the air pump 535, the amount and force of the washing water or washing foam discharged from the spray nozzle 550 will be increased or decreased (discharge speed and discharge force). Pressure). As a result, the washing foam and washing water can be evenly dispersed on the inner surface of the toilet, similar to the description with FIG. 11. That is, the air pump 535 of the foam generating part 560 also functions as a variable part of the spouting water amount similarly to the water pump 516.

In addition, in the above, although the configuration in which the on-off valve 530a is provided in the branch flow path 530 is described as an example, it is not limited to this. For example, a configuration in which a flow path switching valve is provided at the branch portion of the branch flow path 530 and the washing water supply flow path 690 may also be adopted.

That is, the foam generating unit 560 of the present embodiment includes a foam tank 532 between the on-off valve 530a and the spray nozzle 550. The foam tank 532 is supplied with lotion from the lotion tank 533 and generates washing foam. It has the following structure: the generated cleansing foam is discharged from the discharge port 550u of the spray nozzle 550 toward the inner surface of the toilet.

As a result, not only the water film formed by the dispersion of water or warm water on the inner surface of the toilet, but also a foam film formed by washing foam containing lotion. As a result, it is possible to more effectively suppress the adhesion of dirt to the inner surface of the toilet.

In addition, the cleansing foam containing lotion can effectively suppress the odor caused by dirt and the like. In addition, the cleansing foam can give the user a visually clean impression. As a result, the comfort of the user is further improved.

Furthermore, in the above-mentioned embodiment, the description is made as an example of the configuration in which the washing water or washing foam is spread on the inner surface of the toilet when the human body detection sensor 450 detects the entry of a person, but It is not limited to this. For example, it is also possible to provide a configuration in which the scattering is performed by operating the scattering switch 417 provided in the operation unit 210 or the remote controller 400 by a person. Thereby, even when the toilet as a sanitary washing device is not used, when the dirt on the inner surface of the toilet is concerned, the washing foam containing lotion can be sprayed on the inner surface of the toilet to remove the dirt. In addition, it is possible to prevent the formation of stubborn dirt on the draft surface 110b and the like due to drying before it occurs. That is, by operating the spreading switch 417 by the user, a foam film formed of a cleansing foam containing a lotion can be formed on the inner surface of the toilet at any time. As a result, the inner surface of the toilet can be kept clean.

In addition, in the above-mentioned embodiment, the user may use the operation unit 210 or the dispersion selection switch (not shown) of the remote controller 400 in advance to arbitrarily select either of the washing water and the washing foam to be sprayed on the inner surface of the toilet. The composition. In this way, it is possible to arbitrarily choose whether to spread or not according to the state of dirt or odor on the inner surface of the toilet. As a result, unnecessary use of lotion can be suppressed, and cost performance can be improved.

In addition, in the above-mentioned embodiment, the control unit 130 may also be configured to have a configuration in which the washing instruction issuing mode instructed by the operation unit 210 or the switch button of the remote control 400 can be selected.

In this case, in the washing instruction issuing mode, the control unit 130 first turns on the detergent pump 534 of the foam tank 532 after stopping the supply of the detergent from the detergent tank 533 of the foam generating unit 560 to the detergent pump 534 of the foam tank 532. Switch valve 530a. In this way, the water pump 516 delivers the washing water to the foam tank 532. The delivered washing water is supplied from the foam tank 532 to the spreading nozzle 550, and is discharged into the toilet 110.

At this time, first, the path from the foam tank 532 to the spray nozzle 550 is washed with washing water. In this way, if there is a lotion remaining in the path or the spreading nozzle 550, it can be rinsed in advance with washing water. Therefore, it is possible to prevent the clogging of the path or the spreading nozzle 550 caused by the fixation of the lotion, and the rotation failure of the spreading nozzle 550. In addition, the inner surface of the toilet can be washed with washing water in advance.

That is, during the washing operation in the washing instruction issuing mode, the lotion pump 534 is in a stopped state. Therefore, no lotion is supplied to the foam tank 532, and only washing water is supplied. Thereby, the path from the foam tank 532 to the spray nozzle 550 is washed by the supplied washing water. At the same time, the washing water of the washing path can be spread from the spreading nozzle 550 toward the inner surface of the toilet. As a result, the inner surface of the toilet is also washed with the washing water together with the washing of the path.

Furthermore, in the washing operation in the washing command issuing mode, washing is usually performed with washing water that is not temperature-controlled. However, the temperature of the washing water may be heated by the heat exchanger 700 to, for example, about 40° C. and supplied to perform the washing operation. Thereby, the solubility of the remaining lotion in the washing water can be improved, and a more excellent washing effect can be obtained.

In addition, the above-mentioned washing instruction issuing mode may also be configured to arbitrarily perform washing of the path or the inner surface of the toilet by operating the washing switch 223 of the operating unit 210 by the user.

Specifically, as shown in FIG. 4, a washing lamp 223a, such as an LED, is provided in the vicinity of the washing switch 223 of the operation unit 210 set in the washing instruction issuing mode. In addition, when a predetermined time such as 20 days has elapsed after the previous washing was performed, the control unit 130 automatically flashes the washing lamp 223a. With this, it is possible to prevent forgetting to wash, and to prevent the occurrence of clogging of paths and the like beforehand.

In addition, when the cleansing foam is spread on the inner surface of the toilet, the control unit 130 can also make the air booster according to the rotation angle of the spout 550u of the spreading nozzle 550, similar to the output action of the water pump 516 shown in FIG. 12 The output of Pu 535 is changed to spread washing foam from the outlet 550u. Thereby, the cleansing foam can be discharged to be effectively delivered to the front, side, and back of toilets with different distances. As a result, a foam film can be formed on the entire inner surface of the toilet, and the adhesion of dirt can be suppressed.

Specifically, as described using FIG. 11, the distance from the outlet 550u of the dispersion nozzle 550 to the inner surface of the toilet is around 160°, which is the longest (far) rotation angle, and the control unit 130 pumps the air pump 535 The output (air pressure) is set to be larger (higher). Thereby, the air pressure caused by the air pump 535 can be increased, and the force of the washing foam to fly from the discharge port 550u to a distance can be enhanced.

On the other hand, in the vicinity of the rotation angle 340∘ where the distance from the outlet 550u to the inner surface of the toilet is the shortest (close), the output (air pressure) of the air pump 535 is set to be small (lower). Thereby, the air pressure caused by the air pump 535 can be reduced, and the force of the washing foam to fly out is weakened.

That is, the pressure of the air discharged from the air pump 535 is adjusted in accordance with the distance from the outlet 550u of the dispersion nozzle 550 to the inner surface of the toilet. As a result, the cleansing foam can be spit out of the inner surface of the toilet without omission and uniformity.

In addition, in the above-mentioned embodiment, it is also possible to provide a structure further equipped with a dirt detection unit (not shown) that detects dirt on the toilet with an image element such as a CCD (Charge Coupled Device). At this time, the control unit 130 drives the spreading nozzle 550 to go back and forth on the part where the dirt remains based on the detection result of the dirt detection unit, so as to intensively spread the washing foam. Thereby, the dirt adhering to the inner surface of the toilet can be effectively removed. Furthermore, in addition to the method of only going back and forth in the dirt part, the rotation speed of the discharge port 550u of the spreading nozzle 550 passing through the dirt part may also be driven to rotate at a lower speed. In addition, it can also be configured to increase the output of the water pump 516 or the air pump 535 when passing through the dirt part. By this, the same effect can be obtained. ＜4＞The discharge control, function and action by the spreading nozzle in the open and non-seat state of the toilet seat

Hereinafter, using FIGS. 13A and 13B, when a male urinates, the user is not seated on the toilet seat 300, and the toilet seat 300 is almost vertically opened, when the user operates the spreading switch 417 The nozzle discharge control will be described.

At this time, since the user is in a standing posture, the toilet seat 300 is in an opened state. That is, the toilet seat switch detection unit 331 detects the open state of the toilet seat, and the seating detection unit 330 detects the non-seated state.

In addition, in the item <3>, the description is based on the rotating foam dispersing command issued by the control unit 130 (foam application) mode, which rotates the spray nozzle 550 in the direction of the discharge port 550u while rotating the washing foam The rotating foam scattered in the toilet is scattered.

In the item <4>, it is explained that the fixed foam dispersing command issued by the control unit 130 (splash suppression) mode is used to disperse the cleansing foam into the toilet while the direction of the discharging nozzle 550u of the dispersing nozzle 550 is fixed. .

That is, the description is directed to the fixed foam dispersion when the user is not seated on the toilet seat 300 when the user is urinating, and the toilet seat 300 is opened almost vertically.

Specifically, FIG. 13A and FIG. 13B are used to describe the discharge control of the spray nozzle in the fixed foam spray command issuance mode when the user operates the manual splash suppression switch 434 as the spray switch.

Fig. 13A is an explanatory diagram showing the output of the water pump during the discharge operation to the inner surface of the toilet by the dispersion nozzle. Fig. 13B is an explanatory diagram showing the discharge direction of the dispersion nozzle to the inner surface of the toilet.

At this time, since the user is in a standing posture, the toilet seat 300 is in an opened state. That is, the toilet seat switch detection unit 331 detects the open state of the toilet seat, and the seating detection unit 330 detects the non-seated state.

In the above state, the user presses the manual splash suppression switch 434 of the operating unit 210 or the remote controller 400. In addition, the manual splash suppression switch 434 of the operation unit 210 is not particularly shown in the figure.

Thereby, the control part 130 first drives the dispersion nozzle drive part 550a, and, as shown in FIG. 13B, rotates the direction of the discharge port 550u of the dispersion nozzle 550 to a position toward the back of the toilet. Next, the driving of the spray nozzle driving unit 550a is stopped. In the case of this embodiment, as shown in FIG. 13A, the rotation angle of the discharge port 550u is stopped at a position near, for example, 20°. Thereby, the direction of the discharge port 550u will be toward the rear side of the inner surface of the toilet.

Next, as shown in FIG. 13A, the control unit 130 controls the discharge output of the water pump 516 or the air pump 535 that constitutes the water discharge variable part to a "high" output. In addition, in the direction indicated by the arrow in FIG. 13B, washing water or washing foam is discharged from the spray nozzle 550 toward the back of the toilet 110 for a predetermined time. In this embodiment, the predetermined time is set to, for example, 8 seconds.

At this time, the discharge port 550u of the dispersion nozzle 550 stops in the direction of the angle α toward the rear and downward with respect to the rotation axis Ax of the dispersion nozzle 550 shown in FIG. 9. Therefore, in a state stopped in the direction indicated by the discharge port direction AcB in FIG.

That is, after rotating the direction of the discharge port 550u of the dispersing nozzle 550 to the back of the toilet, the control unit 130 controls the water pump 516 to a "high" output to discharge washing foam and the like. Thereby, the water surface above the discharge port 115 in the toilet and the water line above the water line in the toilet are quickly covered by the washing foam etc. flowing down behind. As a result, it is possible to suppress the diffusion of the odor accompanied by excretion of urine and the like and the adhesion of dirt near the water surface 110b of the toilet 110 by the washing foam.

In addition, when the excreted urine falls near the water surface in the toilet 110, the cleansing foam covering the water surface can have a cushioning effect. Thereby, it is possible to suppress the rebound to the outside of the toilet 110. That is, in the direction where the spray nozzle 550 has been fixed, a large amount of washing foam or the like is quickly dispersed to form a foam film on the upper part of the water surface in the toilet 110. Thereby, it is possible to prevent urine from scattering out of the toilet 110 due to bounce or the like.

Furthermore, in the present embodiment, when the fixed foam dispersion command issuance mode (splash suppression mode) is set by the operation of the manual splash suppression switch 434 by the user, the outlet 550u faces the rear side of the toilet. At this position, the rotation drive of the dispersion nozzle drive unit 550a is stopped. Although the control unit 130 uses the "high" output to control the discharge water volume variable unit 516 to discharge the cleansing foam toward the back of the toilet as an example after the stop, the control unit 130 is not limited to this. For example, the fixed position of the spray nozzle 550 for spraying cleansing foam may be any position on the front, center, rear, or left and right sides of the toilet near the discharge port 115 of the toilet 110. That is, it is only necessary to form a state in which washing foam can be discharged, and the washing foam can quickly cover the draft surface 110b and the upper part of the toilet bowl 110 with the washing foam in a short time of, for example, a few seconds. Thereby, the splashing or scattering of urine can be suppressed. In addition, it is possible to more reliably suppress the adhesion of dirt to the vicinity of the water line in the toilet 110 and the upper part thereof.

In addition, in this embodiment, although in the fixed foam dispersing command issuing mode, the control unit 130 discharges cleansing foam from the discharge water volume variable part 516 toward the rear side of the toilet with a "high" output as shown in FIG. 13A. The constitution of etc. is explained as an example, but it is not limited to this. For example, the output of the water discharge variable part 516 may be discharged as a "medium" output.

As described above, the sanitary washing device of this embodiment is provided with the main body 200 provided on the toilet 110, the washing nozzle 831 for washing the human body, the foam generating part 560 for generating washing foam, and the washing water or The spray nozzle 550 for washing foam, and the spouting water volume variable part 516 for changing the flow rate of the washing water sent to the spray nozzle. In addition, the sanitary washing device further includes a spreading nozzle driving unit 550a that drives the discharge port 550u of the spreading nozzle, an on-off valve 530a that opens and closes the water passage to the spreading nozzle, a control unit 130, and an operation unit 210 that gives instructions and settings to the control unit. . In addition, the control unit 130 has the following control actions: a rotating foam dispersing command issuing mode, which disperses washing foam into the toilet while rotating the spray nozzle in the direction of 550u; and a fixed foam dispersing command issuing mode, In a state where the direction of the discharge port 550u of the spray nozzle is fixed, the cleansing foam is sprayed into the toilet as it is.

According to this configuration, when toilet foam is dispersed in the rotating foam dispersion command issuance mode, the control unit 130 rotates and drives the spray nozzle 550u in the direction of the discharge port 550u while dispersing the washing foam from the dispersion nozzle 550 to a wide area in the toilet. Served. Thereby, the inner surface from the front to the rear of the toilet is formed with a foam film by washing the foam, and the adhesion of dirt on the inner surface of the toilet and the vicinity of the water line can be suppressed.

On the other hand, when toilet foam is dispersed in the fixed foam dispersing command issuance mode, the control unit 130 disperses the cleansing foam into the toilet as it is with the direction of the discharging nozzle 550u fixed. Furthermore, a foam film of washing foam is quickly formed on the upper part of the water surface in the toilet. Thereby, the water surface of the upper part of the discharge port in the toilet can be quickly covered with the foam film of washing foam. As a result, the cushioning effect of the cleansing foam can suppress the diffusion of the odor during urination, or the scattering caused by the rebound from the water surface when the urine falls when the male urinates.

Here, with reference to the verification result shown in FIG. 25, the urine scattering suppression effect by the washing foam will be explained.

Fig. 25 is a graph showing the verification result of the splash suppression effect of the foam dispersion in the fixed foam dispersion command issuance mode of the sanitary washing device. The vertical axis of Fig. 25 shows the height (thickness) of the cleansing foam covering the draft, and the horizontal axis shows the elapsed time.

From the results shown in Fig. 25, it can be seen that first, the foam height of the cleansing foam decreases with the passage of time. In addition, it can be seen that when the foam height is about 5 mm or more at the initial stage of the spreading, the scattering can be suppressed compared to the case where there is no foam.

In addition, it can be confirmed that at the initial stage of the spreading, if the foam height is about 10 mm or more, the effect of suppressing the scattering of urine and the like from the bedpan surface of the toilet 110 to the outside becomes remarkable. In this case, it can be seen that the suppression effect is also reduced with the passage of time.

In addition, it is already clear that when the foam height is about 18 mm or more, it is possible to more reliably suppress the scattering of urine and the like from the bedpan surface of the toilet 110 to the outside from the initial stage of spreading to about 2 hours.

According to the above verification results, the foam height on the water surface in the toilet bowl formed by the foam dispersion preferably has a lower limit of 5 mm or more and an upper limit of 50 mm or less. In particular, the range of 10 mm to 50 mm or less is more preferable. In addition, the upper limit of 50 mm is a value specified based on the foam height of the sanitary washing device used in the verification experiment, when the user is seated on the toilet seat, and the accumulated foam does not touch the buttocks. Therefore, in different sanitary washing devices, of course, the upper limit setting can be changed according to the size and shape of the toilet and the toilet seat.

In addition, in the sanitary washing device of the present embodiment, the rotation axis Ax of the discharge port 550u of the rotating nozzle 550d of the rotating spray nozzle 550 is installed in the main body 200 by being inclined in the front-rear direction and the left-right direction. In addition, the inclination in the front-rear direction is arranged with the lower side of the dispersion nozzle 550 inclined to the front side of the toilet 110 with respect to the rotation axis Ax, and the inclination in the left-right direction is arranged with respect to the rotation axis Ax so that the lower side of the dispersion nozzle 550 faces the washing The nozzle 831 side is inclined and arranged.

According to this configuration, when the cleansing foam is spread to the toilet foam of the toilet 110, when the discharge port 550u of the spreading nozzle 550 is directed to the spreading position in front of the toilet, the direction of the discharge port 550u is changed. Becomes high. On the other hand, when the discharge port 550u of the dispersion nozzle is directed to the spreading position behind the toilet where the distance is shortened, the direction of the discharge port 550u is lowered. Thereby, in accordance with the distance from the discharge port 550u of the dispersion nozzle to the inner surface of the toilet, it is possible to spread the washing foam while changing the height of the discharge port 550u of the dispersion nozzle. Therefore, without changing the output of the water pump 516, the washing foam can be spread to the inner surface from the front to the rear of the toilet and form a foam film. As a result, the adhesion of dirt to the inner surface of the toilet can be suppressed.

In addition, in the sanitary washing device of this embodiment, when rotating foam is spread from the spreading nozzle 550 to the toilet 110, the control unit 130 rotates the spreading nozzle driving unit 550a forward so that the direction of the discharge port 550u passes behind the toilet. The front of the toilet is rotated to the back of the toilet. After that, the control unit 130 reverses the dispersion nozzle driving unit 550a so that the direction of the discharge port 550u is rotated from the back of the toilet, through the front of the toilet, and back to the back of the toilet. That is, the control unit 130 is controlled to perform the step action of rotating foam spreading by at least one back and forth rotating action.

According to this configuration, first, the control unit 130 rotates the spray nozzle driving unit 550a forward, and spreads the washing foam while moving the direction of the spray nozzle 550u from the back of the toilet through the front of the toilet to the back of the toilet. After that, the control unit 130 reverses the dispersing nozzle driving unit 550a, and spreads the washing foam while moving the direction of the discharge port 550u from the back of the toilet, to the front of the toilet, and back to the back of the toilet. That is, while rotating the direction of the discharge port 550u of the dispersing nozzle 550 in the forward and reverse directions along the inner peripheral surface of the toilet, the washing foam is spread by at least one back and forth rotation drive. At this time, the output of the water discharge variable portion 516 is controlled to reach the vicinity of the edge of the toilet 110 to spread the cleansing foam to almost the entire circumference of the inner surface of the toilet. Thereby, a foam film can be formed on the inner surface from the front to the back of the toilet, and the adhesion of dirt can be suppressed.

In addition, the sanitary washing device of the present embodiment further includes a human body detection sensor 450 that detects the entry and exit of the user into and out of the toilet. When the human body detection sensor 450 detects that the user enters the toilet, the control unit 130 will spread the rotating foam toward the inner surface of the toilet through at least one back and forth rotation action.

According to this configuration, when the human body detection sensor 450 detects the user's entry into the toilet, it can perform at least one back-and-forth rotation drive in the direction of the spray nozzle 550u to spread the inner surface of the toilet. The rotating foam of the cleansing foam spreads. Thereby, a foam film can be formed on the inner surface of the toilet before use, so as to prevent the adhesion of dirt before it occurs.

In addition, the sanitary washing device of this embodiment is provided with a foam tank 532 in which washing water is delivered by the variable discharge volume part 516 by opening the on-off valve 530a by the control part 130, and the lotion in the lotion tank 533 is supplied to the foam. The lotion pump 534 of the tank 532, and the air pump 535 that supplies air to the foam tank. In addition, the control unit 130 controls to discharge the washing water or washing foam of the foam tank 532 from the spray nozzle 550.

According to this structure, not only water or warm water but also washing foam containing lotion can be discharged to the surface of the washing nozzle 831 or the inner surface of the toilet. Thereby, the cleaning effect and the effect of suppressing the adhesion of dirt can be improved. In addition, the diffusion of odors can be suppressed by washing foam containing lotion. As a result, it is possible to provide the user with a visual sense of cleanliness and comfort during use.

In addition, the control unit 130 of the sanitary washing device of this embodiment has a washing command issuance mode. In addition, the control unit 130 opens the on-off valve 530a in a state where the supply of the lotion from the lotion tank 533 of the foam generator 560 to the lotion pump 534 of the foam tank 532 has been stopped in the washing command issuing mode, The spray water variable part 516 sends the washing water to the foam tank 532 and sprays it from the spray nozzle 550.

According to this configuration, the path from the foam tank 532 to the spray nozzle 550 can be washed with washing water. Thereby, it is possible to prevent the clogging of the path or the spreading nozzle 550 due to the fixation of the lotion, and the rotation failure of the spreading nozzle 550 caused by the fixation of the lotion. In addition, the inner surface of the toilet can be washed with washing water.

In addition, in this embodiment, although the structure which uses a motor as an example of a dispersion nozzle drive part 550a is demonstrated, it is not limited to this. It is also possible to provide a configuration in which the dispersion nozzle 550 is rotated by the reaction when the washing foam is discharged from the discharge port 550u of the dispersion nozzle 550. With this, the configuration can be simplified and power consumption can be suppressed.

In addition, in the present embodiment, although the configuration in which the dispersion nozzle 550 is one is described as an example, it is not limited to this. For example, it is also possible to provide a configuration in which a plurality of spray nozzles are arranged in the following form: a spray nozzle for spraying washing foam near the edge 110a of the toilet 110, and a spray nozzle for spraying washing foam near the discharge port 115 of the toilet 110 Wait. At this time, a plurality of spreading nozzles can be rotated independently, or can be rotated in conjunction with each other. Thereby, the washing foam can be spread to the inner surface of the toilet in a short time.

In addition, in the present embodiment, although the configuration in which the dispersion nozzle 550 is provided with one discharge port 550u is described as an example, it is not limited to this. For example, the spray nozzle 550 may be provided with a plurality of outlets such as an outlet for spraying cleansing foam near the edge 110a of the toilet bowl 110 and a spray outlet for spraying cleansing foam near the outlet 115 of the toilet bowl 110. Thereby, the cleansing foam can be spread on the inner surface of the toilet in a short time.

In addition, in this embodiment, although the spray nozzle 550 is described as an example of a configuration in which the spray nozzle 550 spreads cleansing foam near the edge 110a of the toilet 110 and near the discharge port 115 of the toilet 110, it is not limited to this. For example, in addition to the above, it is also possible to further create a configuration in which the spray nozzle 550 spreads the cleaning foam to the middle position (height) between the edge 110a of the toilet 110 and the discharge port 115. This can further reduce the occurrence of scattering omissions.

In addition, as shown in FIGS. 10, 14 and 15, the sanitary washing device of this embodiment includes a sleeve cover 250 integrally provided on the side of the main body 200 so as to protrude forward. The sleeve cover 250 has a sleeve cover 217 provided in front of the operation part 210 arranged on the upper part, and a lotion tank 533 composed of a container that is visible inside the sleeve cover 217 and built in the foremost part. . In addition, the sleeve cover 250 is provided with a lotion level confirmation window 216 on the front side that can confirm the position of the lotion level of the lotion tank 533.

According to this configuration, the user can easily visually confirm the remaining amount of lotion liquid when using the sanitary washing device. Therefore, the lotion can be replenished before the lotion is used up.

That is, the lotion tank 533 has a lotion injection port 537 with a lotion tank cover 536 above. The lotion tank 533 is arranged at the foremost part in front of the operation part 210 of the sleeve cover 250, and is arranged at the position closest to the front of the toilet. Therefore, the replenishment of lotion liquid becomes easy. In addition, the sleeve cover 217 is provided in front of the operation unit 210. Thereby, when the user replenishes the lotion tank 533, the user can prevent the lotion liquid from being spilled on the operating part 210. In addition, as shown in FIGS. 14 and 15, the lotion injection port 537 is arranged at a lower position than the operation part 210. Thereby, when the lotion liquid is replenished to the lotion tank 533, it is possible to more reliably prevent the lotion from being spilled on the operation part 210.

In addition, the sanitary washing device of this embodiment constitutes the lotion pump shown in FIGS. 6 and 14 with a tube made of a hollow cylindrical tube and a double hose formed by further covering the tube on the outside. Hose 561. In addition, the inner diameter of the lotion pump hose 561 is set to be smaller than the inner diameter of the foam tank hose 562.

With these configurations, even if high pressure is applied from the lotion pump 534 to the lotion pump hose 561, the lotion pump hose 561 can still be prevented from swelling and rupture. Thereby, it is possible to stably disperse the washing foam from the dispersing nozzle 550 into the toilet.

Furthermore, the lotion pump hose 561 is composed of, for example, a double tube in which the outer side of an elastomer resin tube is covered with a heat-shrinkable tube, but the material is not limited to this. That is, it is not particularly limited as long as it is a material that can prevent the lotion pump hose 561 from swelling and breaking by the double tube structure. Thereby, the washing foam can be stably dispersed from the spray nozzle 550.

In addition, as shown in FIGS. 2, 15 and 16, the sanitary washing device of this embodiment is provided with a control unit 130, a spray nozzle 550, a nozzle device, etc., in the interior of a main body 200, and the main body 200 is a main body cover 202 covers the front of the rear body cover 201. In addition, the dispersion nozzle 550 is provided in the front part of the rear body cover 201, and the front and upper parts of the dispersion nozzle 550 are covered by the body cover 202. In addition, the discharge port 550u at the lower part of the dispersion nozzle 550 is configured to be provided in a form open to the inner surface of the toilet.

The above-mentioned embodiment will be specifically explained with reference to FIG. 16.

FIG. 16 is a cross-sectional view showing the center portion of the spreading nozzle 550 provided in the rear body cover 201 cut in the front-rear direction.

The cleansing foam discharged from the discharge port 550u of the spray nozzle 550 is usually discharged toward the inner surface of the toilet in the direction indicated by the dotted line T in FIG. 16.

However, when washing is performed in the above-mentioned washing command issuing mode, washing water without washing foam is discharged from the discharge port 550u of the spray nozzle 550. In this case, as shown by the two-dot chain line S in FIG. 16, the jet of washing water spreads and scatters. Therefore, there is a possibility that the washing water may scatter to the outside of the toilet and wet the floor of the toilet.

Therefore, in this embodiment, as shown in FIG. 16, the scatter guard 550z is provided on the main body cover 202. The scatter guard 550z intercepts the upward jet flow of washing water or the like from the discharge port 550u of the dispersion nozzle 550 that exceeds the upper limit (flying out to the outside), and causes it to fall into the toilet. Thereby, it is possible to prevent the washing foam and washing water discharged from the dispersing nozzle 550 from being sprayed out of the toilet and spreading into the toilet.

In addition to the function of preventing the washing water from being scattered to the outside, the scattering protection section 550z also has a function described below with reference to Figs. 17 to 18.

Fig. 17 is a front view of the main body of the sanitary washing device. Fig. 18 is a side view of the main body of the sanitary washing device. In addition, the two-dot chain line shown in FIGS. 17 and 18 corresponds to the placement surface of the pedestal and the like when the main body 200 is placed.

The main body 200 of the sanitary washing device of this embodiment is configured to be detachable from the toilet 110 through the main body fixing plate 240 shown in FIG. 19.

That is, when the builder or user first installs the toilet, or cleans the dirt near the lower part of the main body 200, the main body 200 is removed from the toilet 110 and placed on a pedestal. The removed main body 200 may be temporarily placed on a pedestal or on the floor, for example.

At this time, the scattering prevention part 550z is protected so that the discharge port 550u of the dispersion nozzle 550 located below the mounting surface of the main body 200 does not come into contact with the temporarily placed pedestal or floor. In this way, damage to the dispersion nozzle 550 can be prevented in advance. That is, as shown in FIG. 17 and FIG. 18, by the scattering prevention part 550z, the contact of the discharge port 550u of the dispersion nozzle 550 and the base can be prevented by the scattering prevention part 550z.

In addition, in the above-mentioned embodiment, although the structure in which the scatter prevention part 550z is formed in the main body cover 202 was demonstrated as an example, it is not limited to this. For example, the scattering prevention part 550z may be formed in the main body 550c of the dispersion nozzle 550, etc. Thereby, a complicated large-scale molding die during molding of the main body cover 202 becomes unnecessary, and a simple molding die can be used to mold the main body cover 202. In addition, the discharge port 550u and the scattering prevention part 550z can be configured with high positional accuracy.

Next, the structure in which the main body 200 is detachable to the toilet 110 will be explained using FIG. 19.

19 is a perspective view of the main body fixing plate 240 and the rear main body cover 201 of the main body 200 in the sanitary washing device. In addition, for the convenience of description, FIG. 19 is illustrated in a state where the control unit 130, the dispersion nozzle 550, the nozzle device, and the like provided inside are omitted.

That is, a mounting bolt (not shown) is inserted through the long hole 241 for position adjustment of the main body fixing plate 240 to fix the main body 200 to the toilet 110.

Specifically, first, the main body fixing plate 240 is aligned with the center of the main body 200 in the left-right direction.

Next, in a state where the rear part of the main body fixing plate 240 has been slightly floated, the main body 200 is slid from the toilet surface toward the main body fixing plate 240. In addition, the main body 200 is pressed into the main body fixing plate 240 until the sound of "click" appears, for example. Thereby, the main body 200 and the main body fixing plate 240 can be fixed to the toilet 110 by the ratchet mechanism.

On the other hand, when the body 200 is removed from the toilet 110, the body detachment button 242 located on the side (side) of the body 200 shown in FIG. . And while pushing in, the main body 200 is pulled out forward. In this way, the main body 200 can be removed from the toilet 110.

As described above, the main body 200 and the toilet 110 can be detachably constructed.

In addition, as shown in FIG. 19, a magnet 243 is embedded in a main body fixing plate 240 made of resin such as polypropylene (PP), and a detachable sensor 244 is mounted on the rear main body cover 201. In this way, the attachment and detachment state of the main body 200 and the toilet 110 can be detected.

Furthermore, the mounting and dismounting sensor 244 is constituted by, for example, a reed switch.

Hereinafter, the detection of the attachment and detachment state of the attachment and detachment sensor 244 will be described using FIG. 20.

Fig. 20 is a partial cross-sectional view showing a state where the main body 200 is fixed to the main body fixing plate 240 in the sanitary washing device.

As shown in FIG. 20, when the main body 200 is installed in the toilet 110, the magnet 243 of the main body fixing plate 240 and the attachment/detachment sensor 244 of the rear main body case 201 are arranged in a close and opposite positional relationship. . At this time, the reed switch as the mounting and dismounting sensor 244 is turned ON by the magnetic force of the magnet 243. Thereby, it can be detected that the main body 200 has been installed on the toilet 110.

On the other hand, when the main body 200 is removed from the toilet 110, the magnet 243 will be separated from the attachment/detachment sensor 244, and the reed switch will be turned off (OFF). In this way, the mounting and dismounting sensor 244 can be used to detect that the main body 200 and the toilet 110 are in the removed state.

Furthermore, in the sanitary washing device of the present embodiment, when the attachment/detachment sensor 244 detects that the main body 200 is removed from the toilet 110, the control unit 130 controls the discharging nozzle 550 not to perform the discharge operation. Therefore, even if the user presses buttons such as the manual foam application switch 433 or manual splash suppression switch 434 of the remote control body 401 in the state where the main body 200 has been removed from the toilet 110, the control unit 130 will not execute The discharging operation performed by the spray nozzle 550. In this way, it is possible to prevent undesirable conditions such as accidental spraying of washing water or washing foam onto the floor or people.

On the other hand, even when the attachment/detachment sensor 244 detects that the main body 200 is removed from the toilet 110, the control unit 130 still controls not to prohibit the discharge operation of the buttocks washing nozzle 831 and the pudendal washing nozzle 832. This is because if the mounting and dismounting sensor 244 fails, the control unit 130 may misrecognize that the main body 200 has been removed from the toilet 110. Therefore, the control unit 130 controls the buttocks washing and the vagina washing, which are the basic functions of the sanitary washing device, to be executable. Thereby, it is possible to suppress a decrease in convenience for the user.

As described above, the control unit 130 controls the sanitary washing device based on the detection of the attachment/detachment state of the attachment/detachment sensor 244.

Hereinafter, with reference to FIG. 21, the operation and control of each part when the rotating foam is spread in the sanitary washing device of the present embodiment will be described.

Fig. 21 is a timing chart when the rotating foam is spread in the sanitary washing device.

As shown in FIG. 21, at time N1, the user presses the manual foam application switch 433 of the remote controller body 401. Thereby, the control unit 130 rotates the lotion pump 534 in the reverse direction at the time point N2, for example, 2 seconds, and then rotates the lotion pump 534 forward at the time point N3. At the same time, the control unit 130 will start the operation of the water pump 516 and the air pump 535 at the time point N3. Thereby, lotion, water, and air can be supplied into the foam tank 532 to generate washing foam.

The generated cleansing foam is sprayed in a rotating foam from the discharge port 550u of the spray nozzle 550 toward the inner surface of the toilet. As a result, the adhesion of dirt to the inner surface of the toilet can be suppressed, and the dirt can be easily removed.

At this time, the discharge port 550u of the dispersion nozzle 550 is rotationally driven by, for example, the dispersion nozzle drive part 550a which is a stepping motor. Specifically, while moving from the stop position at the time point N3 (20° in FIG. 11) to the limit position at the time point N6 (340° in FIG. 11), the foam is spread from the discharge port 550u. After that, while reversing from the limit position at the time point N6 to the stop position at the time point N9, the foam is dispersed and returned.

Furthermore, at the time point N11, the operation of the water pump 516 and the air pump 535 is automatically stopped by, for example, a timer control. In this way, the spread of the rotating foam is automatically ended.

At this time, during the period from the time point N3 to the time point N11 when the rotating foam is spread, the control unit 130 continuously operates the water pump 516 and the air pump 535. On the other hand, during the period from the time point N3 to the time point N4, the period from the time point N6 to the time point N7, and the period from the time point N9 to the time point N10, the control unit 130 will intermittently operate the lotion pump 534 into a forward rotation. stop.

Furthermore, the above-mentioned intermittent operation action is based on experimental results, and it is possible to efficiently mix lotion, water, and air in the rotating foam dispersion, and more stably generate the action of washing foam. With the intermittent operation of the lotion pump 534, washing foam can be stably generated. As a result, unnecessary use of lotion can be prevented, and labor for replenishing lotion can be reduced.

In addition, in the sanitary washing device of the present embodiment, the intermittent operation of the lotion pump 534 is set to operate for 2 seconds in a 6-second cycle, for example.

In addition, in the timing chart shown in FIG. 21, in order to show the execution according to the needs, the operation of the heat exchanger 700 is drawn with a broken line. The reason is that if the temperature of the water supplied from the water pump 516 to the foam tank 532 is lower than 20° C. when the rotating foam is spread, there is a concern that the washing foam cannot be stably generated. Here, when the water temperature is low, the heat exchanger 700 is used to perform heating control to heat the washing water to, for example, about 20°C. In addition, what is shown is the state of operating the foam tank 532 when the heated washing water is supplied to the foam tank 532. In this way, the foamability can be prevented from being reduced, so that a better washing foam is generated and supplied to the foam tank 532.

Furthermore, in the timing chart shown in FIG. 21, the lotion pump 534 is reversed from the time point N2 before the time point N3 at which the spin bubble spreading starts to the time point N3. The reason is that in this embodiment, a tube pump is used in the lotion pump 534. The tube pump sends out the lotion in the tube by the flattening action of the roller. Therefore, by the reversal action in front, the lotion liquid flows backward from the outlet side of the tube on the part of the squashed tube, and the squashed part is restored to a cylindrical shape. And, in a state where it has returned to the shape of the tube, the lotion pump 534 is rotated forward. Thereby, a stable amount of lotion liquid can be sent out to the spreading nozzle 550.

In addition, as shown in the timing chart of FIG. 21, from the time point N11 to the time point N14, the control unit 130 executes the operation of returning the spreading nozzle driving unit 550a from the stop position to the origin position. Specifically, the spreading nozzle drive unit 550a is driven until it comes into contact with the origin position. At this time, the dispersion nozzle driving unit 550a presses the rotation detection micro switch arranged at the origin position. Thereby, the control unit 130 recognizes the origin position of the dispersion nozzle driving unit 550a formed by a stepping motor. After that, the control unit 130 drives the spreading nozzle drive unit 550a to return to the stop position. The reason is that the stepping motor may slip due to, for example, some increase in rotational load. Therefore, the rotation drive corresponding to the number of drive steps cannot be completed, and a deviation occurs between the number of drive steps and the amount of rotation. Then, as described above, the operation of resetting the origin position of the dispersion nozzle driving unit 550a is executed. Thereby, it is possible to reset the stop position, which is the start position of the spraying of the rotating foam of the spray nozzle driving portion 550a, to the correct position, and start driving. As a result, the origin position of the dispersion nozzle driving portion 550a can be used as a reference, and the rotation angle of the dispersion nozzle 550 can be specified with high accuracy, so that the rotating foam dispersion can be constantly performed at a stable position.

In addition, for some reasons, for example, the lotion is fixed around the discharge port 550u of the dispersion nozzle 550, and the dispersion nozzle driving unit 550a cannot be rotationally driven. In this case, it is possible to easily detect the malfunction of the dispersion nozzle driving part 550a by the rotation detection microswitch being pressed by the reset operation of the dispersion nozzle driving part 550a to the origin position.

In addition, when the rotating foam is spreading, if the turn-on signal is not input from the rotation detection micro switch, the washing lamp 223a (refer to FIG. 4) arranged in the operation part 210 is executed in the light display mode described below To notify users of bad conditions. Thereby, the user can be urged to operate the above-mentioned washing switch 223, and the washing operation can be executed.

Furthermore, in the sanitary washing device of this embodiment, the time from the start time point N3 to the end time point N12 in the rotating foam spreading shown in the time chart of FIG. 21 is set to, for example, about 15 seconds . In addition, about 15 seconds is only an example, and of course, it may be changed to about 10 seconds or about 25 seconds according to the size of the toilet.

Here, the lighting display of the above-mentioned washing lamp 223a will be specifically described.

With respect to the spin bubble spreading time set as described above, when the time delay until the rotation detection micro switch is pressed is, for example, about 10% or more later, the washing lamp 223a is caused to repeat "flash" and "flash". Lights up display in the second flashing action. Thereby, the user can be urged to press the washing switch 223 and perform the washing operation.

In the washing operation, washing water heated to about 40° C. by the heat exchanger 700 is discharged to the foam generating portion 560 and the spray nozzle 550, and washing is performed, for example, for about 3 minutes. By the washing operation, the bubble generating part 560, the spreading nozzle 550, etc. can be washed with the heated washing water. As a result, it is possible to prevent the lotion from fixing or clogging the foam generating portion 560, the spreading nozzle 550, etc., and stable rotating foam spreading can be performed.

In the above state, when the washing operation is not performed, the spray nozzle 550 becomes hard due to the lotion or the like, which further deteriorates the operation. In this case, relative to the set spin bubble spreading time, when the time delay until the rotation detection micro switch is pressed is, for example, about 20% or more, the washing lamp 223a is caused to repeat "flash, flash", "flash" and "flash". "Flashing, flashing" 2 flashing actions to light up the display. Thereby, the user can be urged to press the washing switch 223 to perform a washing operation, and to clean the vicinity of the discharge port 550u of the dispersion nozzle 550 while brushing, for example, with a toothbrush.

As described above, by illuminating and displaying the washing lamp 223a, it is possible to urge the user to respond based on the detection of the malfunction of the dispersion nozzle driving section 550a.

In addition, the flow path switching timing chart shown in FIG. 21 shows the following actions: at time points N2 to N3, the washing water from the water pump 516 of the water circuit shown in FIG. 6 is supplied The destination is switched from the nozzle device 800 side to the bubble generating part 560 side. In addition, what is shown is the operation of switching the supply destination of the washing water from the side of the bubble generating unit 560 to the side of the nozzle device 800 at the time points N11 to N13.

Specifically, at the time points N2 to N3, the fluid regulating valve 517 is closed, the on-off valve 530a is opened, and the supply destination of the washing water is switched to the foam generating unit 560. On the other hand, at the time points N11 to N13, the on-off valve 530a is closed, the fluid regulating valve 517 is opened, and the supply destination of the washing water is switched to the nozzle device 800.

Furthermore, although the on-off valve 530a is taken as an example in the above description, it is not limited to this. For example, it may be configured to switch the flow path with a flow path switching valve such as a three-way valve arranged at a branch location where the washing water supply flow path 690 is branched to the branch flow path 530.

As described above, the actions and control of each part of the sanitary washing device when the rotating foam is spread can be performed.

Hereinafter, the operation and control of each part during the washing operation in the sanitary washing device will be described with reference to FIG. 22.

Fig. 22 is a timing chart during the washing operation in the sanitary washing device.

As shown in FIG. 22, at the time point N1, when the user presses the washing switch 223 of the operation unit 210, the control unit 130 sets the washing instruction issuing mode. Thereby, the control unit 130 switches the supply destination of the washing water from the nozzle device 800 side to the bubble generating unit 560 side at the time points N2 to N3. In addition, during the period of about 2 minutes from time points N3 to N8, with the lotion pump 534 stopped, the water pump 516 heats the washing water that has been heated to about 40°C by the heat exchanger 700 Transported to the foam box 532. The sent washing water is ejected from the spray nozzle 550 into the toilet.

Next, during about 1 minute from time points N8 to N10, the control unit 130 activates the air pump 535. In this way, the air pump 535 can be used to send the air and the washing water heated to about 40° C. into the foam tank 532 and perform washing.

That is, during the washing operation of washing and washing, first, only washing water is sent to the foam tank 532. In addition, the air pump 535 is activated from the middle of the water supply to add air to the foam tank 532 and perform washing. In this way, first, a large amount of lotion components remaining in the foam tank 532 and the flow path are discharged from the dispersing nozzle 550 into the toilet quickly and efficiently by the washing water. After that, the force of the bubbles (air) formed by the air pump 535 is added to supply it into the foam tank 532. At this time, the air bubbles will act to wash even a small amount of remaining lotion ingredients. As a result, effective washing and washing can be performed in a short time.

Then, when the above-mentioned about 3 minutes of washing is finished, the control unit 130 reverses and rotates the lotion pump 534 at the time points N10 to N14. Thereby, the lotion pump 534 is set to a standby operation state, so that the next rotating foam spreading or fixed foam spreading can start normally. In addition, the washing operation is automatically ended by, for example, timer control.

As described above, the operation and control of each part during the washing operation in the sanitary washing device can be performed.

Hereinafter, the operation and control of each part when the fixed foam in the sanitary washing device is spread will be described with reference to FIG. 23.

Fig. 23 is a timing chart when the fixed foam is dispersed in the sanitary washing device.

As shown in FIG. 23, at the time point N1, when the user presses the manual splash suppression switch 434 of the remote controller body 401, the control unit 130 sets the fixed foam distribution command issuing mode (foam application mode). Thereby, at the time point N2, the control unit 130 reverses the lotion pump 534 for 2 seconds, and then causes it to rotate forward at the time point N3. In addition, at the time point N3, the control unit 130 will start the operation of the water pump 516 and the air pump 535. Thereby, lotion, water, and air can be supplied to the foam tank 532 to generate washing foam.

The generated cleansing foam is spread from the discharge port 550u of the spreading nozzle 550 toward the inner surface of the toilet. At this time, by spreading the fixed foam of the cleansing foam on the inner surface of the toilet, the foam can be accumulated on the water surface of the toilet to a height of about 10mm (refer to Figure 25) to cover it. Moreover, the cushioning effect of the cleansing foam suppresses, for example, the splashing of urine when a man urinates.

In addition, the timing chart of the fixed foam dispersing in FIG. 23 and the timing chart of the rotating foam dispersing in FIG. 21 differ in the operation of the discharge port 550u of the dispersing nozzle 550.

That is, in the case of performing the rotating foam spray shown in FIG. 21, the spray nozzle drive part 550a can rotate the discharge port 550u of the spray nozzle 550. On the other hand, in the case of performing the fixed foam dispersion shown in FIG. 23, it is different in the following point: the dispersion nozzle driving section 550a does not rotate the discharge port 550u of the dispersion nozzle 550, but is in a fixed state. Spread cleansing foam.

The timing chart shown in FIG. 23 other than the above is the same as the timing chart shown in FIG. 21. Therefore, the description overlapping with FIG. 21 is omitted.

Here, although the origin position, stop position, and limit position of the spreading nozzle drive part 550a shown in the timing chart of FIGS. 21 to 23 are illustrated by taking the angular positions shown below as an example, they are not Limited by this.

That is, although the origin position is 0° (just behind) as shown in Fig. 11, the stop position is 20° (clockwise) as shown in Fig. 11, and the limit position is shown in the figure. The position of 340° (clockwise) shown in 11 is taken as an example for illustration, but it is not limited to this. For example, the position of the origin may be 5° (clockwise from directly behind). In addition, the stop position may be a position of 60° (clockwise from directly behind). In addition, the limit position is 300° (clockwise).

Hereinafter, the operation when the fixed foam shown in FIG. 23 is spread when the stop position is set to 60° will be described.

First, when the fixed foam dispersing command issuance mode is set, the control unit 130 uses the dispersing nozzle driving unit 550a to stop the direction of the discharge port 550u at a stop position about 60° clockwise from the rear. Perform fixed foam spreading immediately.

At this time, the control unit 130 drives the dispersion nozzle drive unit 550a, and the direction of the discharge port 550u is in advance at a position of approximately 60° which is a stop position. In addition, in the standby state, when the fixed foam is instructed to be sprayed, the control unit 130 immediately discharges cleansing foam toward the inner surface of the toilet without moving the spray nozzle 550. Thereby, before the male starts to urinate, a foam film having a foam height required for splash suppression can be quickly formed on the water surface in the toilet.

In this case, if the direction of the stop position of the discharge port 550u is set to the above-mentioned 50°~70° (approximately 60°) position, the following effects can be obtained in particular. That is, if the washing foam is discharged at the above-mentioned stop position, the washing foam will hit the inclined surface of the inner surface of the toilet. The cleansing foam sprayed on the inclined surface flows down toward the water surface near the discharge port 115 by rotating on the inclined surface of the inner surface of the toilet. Thereby, a foam film of washing foam can be formed on the entire water surface in a short time.

Furthermore, in this embodiment, although the configuration of performing the rotating foam spreading shown in FIG. 21 when the manual foam application switch 433 of the remote controller body 401 is pressed is taken as an example for description, it is not limited to this. It can also be set such that, for example, after defecation (that is, after use in a toilet), rotating foam spreading is automatically performed. In addition, it can also be set to automatically perform rotating foam spreading at regular intervals. Thereby, the dirt is less likely to adhere to the inner surface of the toilet, and the dirt can be more easily removed.

In addition, by automatically spreading the rotating foam at regular intervals, it can effectively suppress the formation of dirt near the waterline in the toilet, especially the formation of ring-shaped stains.

At this time, in the case where the rotating foam spreading is performed by automatic operation after defecation, in the sanitary washing device of this embodiment, it is set such that the seating sensor 330 detects the user's standing up from the toilet seat 300 , And after about 60 seconds, for example, the spin bubble spreading is performed in 15 seconds.

On the other hand, it is set such that when a male who is not seated on the toilet seat urinates, when the toilet seat opening and closing sensor 331 detects that the toilet seat 300 is closed, for example, after about 60 seconds, the time is 15 seconds. The time to perform a rotating bubble spread.

Furthermore, in the above description, although the sensor detects and executes the rotating foam dispersion after about 60 seconds, the description is not limited to this. The switch of the remote controller main body 401 can also be arbitrarily changed to, for example, about 10 seconds later, 25 seconds later, or the like. In this way, it is possible to adjust the time before the start of the rotating foam spreading to an arbitrary time according to the user's usage mode.

In addition, in the above description, about 15 seconds is taken as an example as the time to perform the rotating foam dispersion, but it is not limited to this. The switch of the remote controller main body 401 can also be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of foam spread can be adjusted arbitrarily according to the size of the toilet, etc.

In addition, in this embodiment, although the configuration of performing the fixed foam dispersion shown in FIG. 23 when the manual splash suppression switch 434 of the remote control body 401 is pressed is taken as an example for description, it is not limited to this. For example, it may be set to automatically perform fixed foam spreading when the toilet seat is opened. In this way, when the man urinates, he opens the toilet seat 300, and the fixed foam spreading can be automatically performed. As a result, it is possible to effectively suppress the splashing of urine when the male urinates.

Furthermore, it may be configured that when the toilet seat is set to be opened and the fixed foam spreading is performed in an automatic operation mode, when the toilet seat 300 is opened, the fixed foam spreading is performed immediately after, for example, about 15 seconds.

In addition, in the above, although about 15 seconds is used as an example for the fixed foam spreading time, it is not limited to this. The switch of the remote controller main body 401 can also be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of foam spread can be adjusted arbitrarily according to the size of the toilet, etc.

As described above, the actions and control of each part of the sanitary washing device when the fixed foam is spread can be performed.

Hereinafter, FIG. 24 is used to describe the configuration of the automatic operation of the above-mentioned fixed foam spreading or rotating foam spreading in the sanitary washing device.

Fig. 24 is a diagram illustrating the selection and setting of automatic operation when the fixed foam is spread or when the rotating foam is spread in the sanitary washing device.

In addition, the automatic operation at the time of dispersing the fixed foam or the dispersing of the rotating foam can be selected every time the automatic selection setting switch 236 of the operation part 210 is pressed to select a preferred setting.

Specifically, as shown in the left diagram of FIG. 24, an operation switch 220 is arranged on the operation unit 210 and an automatic selection setting switch 236 is arranged. Next to the automatic selection setting switch 236 are arranged an automatic rotating dispersion lamp 236a after use, an automatic rotating dispersion lamp 236b at a fixed time interval, and an automatic fixed foam dispersion indicator lamp 236c when the toilet seat is turned on. In addition, every time the automatic selection setting switch 236 is pressed, the lamps will light up in the order indicated by the arrow in the right figure of FIG. 24. In this way, 3 types of automatic operation can be set in any combination according to the user's preference.

Specifically, H0 indicates that the automatic rotating dispersion lamp 236a after use, the automatic rotating dispersion lamp 236b at a fixed time interval, and the automatic fixed foam dispersion indicator lamp 236c when the toilet seat is turned on are all turned off. In other words, H0 indicates that all three automatic operations are in the "off" state.

When the automatic selection setting switch 236 is pressed once from this state of H0, it will be in the H1 state in which only the automatic rotating scattering lamp 236a lights up after use. That is, every time the automatic selection setting switch 236 is pressed once, the setting is switched to the state of H2, H3...H6. In addition, when the automatic selection setting switch 236 is pressed once from the state of H6, it will be in the state of H7 in which all three types of automatic operations are "on". Furthermore, in the lamp display in Fig. 24, the ○ mark indicates the "off" state equivalent to the light off, and the ● mark indicates the "on" state equivalent to the light on.

For example, in the conditions of H2, H4, H6, and H7 in which the rotating foam spreading is set by automatic operation at regular intervals as shown in FIG. 24, the rotating foam spreading described in the timing chart of FIG. 21 can be used. It is executed in an automatic manner every, for example, about 3 hours. Thereby, it is possible to suppress the formation of dirt near the water line in the toilet, especially the formation of ring-shaped dirt.

Furthermore, the above-mentioned settings that are executed every about 3 hours can be changed to, for example, every 6 hours, every 12 hours, every 24 hours, etc. by the switch of the remote control body 401. Arbitrary setting. This reduces the number of automatic operations during long periods of absence, and can be adjusted arbitrarily according to the user's situation.

As described above, the automatic operation settings for fixed foam spreading and rotating foam spreading can be selected and executed. (Embodiment 2)

Hereinafter, the sanitary washing device in the second embodiment will be described with reference to Figs. 27 to 29. Figs.

Fig. 27 is a perspective view of the sanitary washing device in the second embodiment. Fig. 28 shows a schematic diagram showing a cross section of a main part of the sanitary washing device in this embodiment. Fig. 29 is a block diagram of a control unit in the sanitary washing device.

As shown in FIGS. 27 and 28, the sanitary washing device of this embodiment is constituted by a so-called toilet-integrated sanitary washing device 1000 in which the toilet 110 and the main body 200 are integrated.

In addition, in FIG. 27, in order to explain the structure in the toilet 110, the toilet seat 300 and the seating sensor 330 shown in FIG. 1 which have been described in the first embodiment are not shown. However, the sanitary washing device 1000 shown in FIG. 27 is also provided with a toilet seat and a seat sensor in the same manner.

That is, the sanitary washing device 1000 of this embodiment is different from the so-called additional type sanitary washing device 100 described in the first embodiment in which the main body 200 is installed on the toilet 110 later. In addition, since the basic structure and function are the same as those of the sanitary washing device 100 of the first embodiment, detailed descriptions are omitted. For example, the sanitary washing device 1000 and the sanitary washing device 100 of the first embodiment are provided with a configuration for performing a foam spreading operation similarly to the sanitary washing device 100 of the first embodiment.

Specifically, the sanitary washing device 1000 further includes a toilet washing remote control 900 and a toilet washing flow path 920, and the toilet washing remote control 900 includes a flush switch 910, and the operation of the control unit 130 In point, it is different from the sanitary washing device 100 of the first embodiment. The toilet flushing flow path 920 has one end connected to, for example, an external water supply connection port (refer to FIG. 6). The other end of the toilet flushing flow path 920 is provided with a toilet spout 940. The toilet spout 940 may be arranged on the right side of the upper part of the toilet, for example, about 1/3 of a circle from the back, and the edge 950 adjacent to the front position.

In addition, the toilet flushing flow path 920 is provided with a flush valve 930 in the middle. The flush valve 930 will open and close the toilet flushing flow path 920 according to the signal of the flush switch 910. In addition, when the flush valve 930 is opened, the water supplied from the outside may be discharged from the toilet spout 940 to the vicinity of the edge 950 along the inner circumference of the toilet 110, for example.

Furthermore, as shown in FIG. 29, the control unit 130 includes a signal receiving unit 131, a signal decoding unit 132, and a signal storage unit 133. The signal receiving unit 131 receives the toilet cleaning signal from the remote controller 900 for toilet cleaning. The signal interpretation unit 132 will interpret the toilet flushing signal. The signal storage unit 133 stores the toilet flushing signal. Furthermore, the toilet flushing signal is in the form of, for example, infrared rays and is communicated by wireless means.

That is, when the control unit 130 receives the toilet flushing signal from the toilet flushing remote controller 900, it opens the flush valve 930 of the toilet flushing flow path 920. Thereby, water is discharged from the toilet water spout 940 of the toilet washing flow path 920 along the inner circumference of the toilet 110 in the vicinity of the edge 950 of the upper part of the toilet. The spit out water will flow to the lower part of the toilet while swirling around the part adjacent to the edge 950 of the upper part of the toilet, and be discharged from the toilet drain 960. At this time, the inner surface of the toilet 110 can be cleaned evenly by the flowing water.

Specifically, after using the toilet, the user can operate the flush switch 910 of the remote controller 900 for toilet flushing. At this time, a toilet flushing signal from the remote controller 900 for toilet flushing can be transmitted. When receiving the toilet flushing signal, the control unit 130 opens the flush valve 930 for a predetermined time. Thereby, the sanitary washing device 1000 performs toilet flushing after defecation, which is the so-called toilet flushing.

The sanitary washing device 1000 is configured as described above.

Hereinafter, the operation and function of the sanitary washing device 1000 different from those of the sanitary washing device 100 of the first embodiment will be mainly described.

First, for example, after using the toilet, the user will press the flush switch 910. Thereby, the toilet flushing signal from the remote controller 900 for toilet flushing can be transmitted. The sent toilet flushing signal will be received by the control unit 130 in the main body 200. In addition, the control unit 130 opens the flush valve 930 of the toilet washing flow path 920. Thereby, water is discharged from the toilet water spout 940 of the toilet washing flow path 920 along the inner circumference of the toilet 110 in the vicinity of the edge 950 of the upper part of the toilet. The discharged water will flow to the lower part of the toilet while swirling around the edge 950 of the upper part of the toilet, and be discharged from the toilet drain 960.

At this time, the control unit 130 uses the signal receiving unit 131 to receive a toilet washing signal from the remote controller 900 for toilet washing when washing the toilet with water discharged from the toilet discharge port 940. When the toilet flushing signal is received, the control unit 130 rotates the discharge port 550u of the dispersion nozzle 550 to be, for example, toward the vicinity of the toilet discharge port 940. In addition, the control unit 130 discharges cleansing foam toward the water discharged from the toilet water discharge port 940.

That is, from the discharge port 550u of the dispersion nozzle 550, the washing foam is discharged toward the water near the toilet discharge port 940 which is discharged from the toilet discharge port 940. With this, it is possible to perform strong washing with water mixed with washing foam even at the position closer to the upper edge 950 of the toilet that cannot be fully reached by the foam dispersion by the dispersion nozzle 550.

Specifically, first, the water discharged from the toilet water spout 940 will flow around the inner circumference of the vicinity of the edge 950 of the upper part of the toilet while gradually flowing to the lower part of the toilet.

At this time, the control unit 130 disperses the washing foam from the discharge port 550u of the dispersing nozzle 550 toward the water in the vicinity of the toilet discharge port 940 to be discharged. Thereby, the cleansing foam is mixed with the water discharged from the toilet water discharge port 940. In addition, while mixing the washing foam and water, it swirls around the inner circumference of the vicinity of the edge 950 of the upper part of the toilet in the toilet 110, and gradually flows to the lower part of the toilet. Therefore, from the vicinity of the edge 950 of the upper part of the toilet to the lower part where the drain port 960 of the toilet is located, water mixed with washing foam is widely delivered. Thereby, the inner surface of the toilet can be cleaned more reliably with water mixed with cleansing foam without uneven cleansing. As a result, the generation of dirt and the like can be effectively suppressed.

In addition, in the above-mentioned embodiment, although the structure in which washing foam is discharged from the spray nozzle 550 toward the water near the toilet spout 940 at the time of toilet washing is demonstrated as an example, it is not limited to this. For example, it may be configured such that not only the vicinity of the toilet water discharge port 940 but also the inner surface of the toilet while washing foam is sprayed, water is discharged from the toilet water discharge port 940.

In addition, in the above-mentioned embodiment, although it is not mentioned in particular about the time of spraying the washing|cleaning foam with respect to the water in the vicinity of the toilet spout 940 from the spray nozzle 550, it may perform at the following time.

For example, the time when the washing foam is sprayed from the spray nozzle 550 and the time when the water is sprayed from the toilet spray port 940 may be the same time. Alternatively, after the water starts to be discharged from the toilet discharge port 940, a time lag may be provided to disperse the washing foam from the dispersing nozzle 550. No matter at any point in time, the same effect can be obtained by powerfully flushing water mixed with cleansing foam in the toilet in a way that it is delivered widely.

In addition, in the above-mentioned embodiment, although there is no special description, after the toilet is cleaned, the control unit 130 may perform the following operations.

Specifically, the control unit 130 executes the rotating foam spreading operation similarly to the foam spreading described in the first embodiment, and this rotating foam spreading operation rotates the direction of the discharge port 550u of the spreading nozzle 550 and drives it. Spread the cleansing foam in the toilet. Thereby, after the toilet is cleaned, a foam film is formed on the inner surface from the front to the back of the toilet in advance. As a result, the adhesion of dirt can be effectively suppressed.

Furthermore, as described above, the control unit 130 of the sanitary washing device 1000 of the present embodiment includes the signal receiving unit 131, the signal decoding unit 132, and the signal storage unit 133 as shown in FIG. 29. Therefore, the user does not need to newly purchase a sanitary washing device including a toilet.

In other words, the user only needs to install the newly purchased main body 200 in the toilet 110 that can be used to clean the toilet with the remote controller 900 for toilet cleaning. Specifically, the control unit 130 of the newly purchased main body 200 receives a toilet flushing signal from the remote controller 900 for toilet flushing. In addition, the control unit 130 discharges cleansing foam from the spray nozzle 550 when the toilet is cleaned. As a result, the water mixed with the washing foam can be widely delivered to the toilet 110 for washing. In addition, after the toilet is cleaned, the control unit 130 disperses the cleansing foam from the spray nozzle 550 toward the inner surface of the toilet. Thereby, a foam film can be formed on the inner surface of the toilet to effectively inhibit the adhesion of dirt.

Hereinafter, the configuration of the toilet flushing signal transmitted from the remote controller 900 for toilet flushing will be described in more detail with reference to FIG. 30.

Fig. 30 is a schematic diagram illustrating the data structure of a toilet washing signal from a remote controller for toilet washing in the sanitary washing device.

Generally, the toilet cleaning signal sent to the toilet 110 capable of toilet cleaning varies from manufacturer to manufacturer. However, as shown in FIG. 30, the toilet flushing signal is basically composed of data having the same leader unit 134, code unit 135, and trailer unit 136.

Specifically, the guiding portion 134 is composed of a long ON signal and a short OFF signal.

Therefore, the control unit 130 can use the signal decoding unit 132 to determine the guide unit 134 of the toilet washing signal received by the signal receiving unit 131.

In addition, the bit data signal constituting the code unit 135 may be transmitted after the guide unit 134. Therefore, the signal interpretation unit 132 judges the bit data signal of the code unit 135 as "0" and "1" for each bit. In addition, the control unit 130 stores the determined bit data signals in the signal storage unit 133 in sequence.

Then, the signal interpretation unit 132 will determine the tail portion 136 that contains a long OFF signal. Thereby, the control unit 130 determines that the toilet flushing signal transmitted from the toilet flushing remote controller 900 has ended.

That is, even if it is the toilet cleaning signal from the toilet cleaning remote controller 900 from a different manufacturer, the control unit 130 of the newly purchased main body 200 still receives the toilet cleaning signal with the signal receiving unit 131 according to the above procedure. . Then, the signal interpretation unit 132 interprets the toilet flushing signal. In addition, the decoded content is stored in the signal storage unit 133. In this way, from the next time on, the control unit 130 can receive the toilet washing signal from the toilet washing remote controller 900 for toilet washing of different manufacturers according to the stored content. As a result, when the control unit 130 of the new main body 200 receives the toilet flushing signal, it can control the spreading nozzle 550 and the like, and start the foam spreading action.

Specifically, the control unit 130 of the new main body 200, like the control unit before replacement, discharges washing foam from the spray nozzle 550 when the toilet is washed. In addition, the control unit 130 may send water mixed with washing foam to the toilet 110 widely to perform toilet washing.

In addition, after the toilet is cleaned, the control unit 130 of the new main body 200 spreads the cleansing foam on the inner surface of the toilet from the spray nozzle 550. Thereby, a foam film can be formed on the inner surface of the toilet to effectively suppress the adhesion of dirt.

In addition, the foam after the toilet is cleaned, and the toilet cleaning time from the beginning of the toilet cleaning to the end of the toilet cleaning will vary depending on the manufacturer. However, even if, for example, the spraying of the cleaning foam on the inner surface of the toilet is performed after 1 minute or 5 minutes after the completion of the toilet cleaning, there is no difference in the effect of suppressing the adhesion of dirt. Therefore, in the present embodiment, the control unit 130 is set to start the foaming of the toilet after washing the toilet 3 minutes after receiving the toilet washing signal. However, of course even if it is not 3 minutes.

In addition, in the above-mentioned embodiment, although the configuration in which the flush switch 910 is provided separately from the remote controller 400 and the toilet flushing remote controller 900 is separately provided as an example, it is not limited to this.

Spit out water from the surface or near the spit of the toilet.

According to this structure, the control unit can open the flush valve according to the toilet flushing signal generated by the operation of the flush switch, and spit out the water flushing the inner surface of the toilet from the toilet spouting port of the toilet flushing flow path. At this time, the washing foam is discharged from the spray nozzle toward the inner surface of the toilet or the water discharged from the vicinity of the toilet spout. Thereby, the water mixed with the washing foam will flow to the lower part of the toilet while swirling around the vicinity of the edge of the upper part of the toilet. That is, since the water containing the washing foam is spit out to be widely delivered to the inner surface of the toilet, the generation of the area where the washing foam is not spread can be suppressed. As a result, the inner surface of the toilet can be cleaned uniformly and effectively, and dirt can be suppressed.

In addition, the control unit of the sanitary washing device of the present invention may also be configured as follows: after the toilet is cleaned, the spray nozzle is rotated in the direction of the discharge port, and the washing foam is spread on the inner surface of the toilet. . Thereby, a foam film can be formed on the inner surface of the toilet to suppress the adhesion of dirt.

In addition, the control unit of the sanitary washing device of the present invention can also be configured as follows: a signal receiving unit for receiving a toilet washing signal, a signal decoding unit for interpreting the toilet washing signal, and a signal storage for storing the toilet washing signal Department.

According to this structure, the user does not need to newly purchase a toilet-integrated sanitary washing device including a toilet. That is, the user can install the newly purchased body on the toilet that can be used to clean the toilet. In this way, the control unit of the newly purchased body will receive the toilet flushing signal. In addition, the control unit may make it to discharge washing foam from the spray nozzle when washing the toilet. As a result, water mixed with cleansing foam can be widely delivered to the toilet and cleaned. In addition, after the toilet is cleaned, the control unit disperses the cleansing foam toward the inner surface of the toilet from the spray nozzle. Thereby, a foam film can be formed on the inner surface of the toilet to suppress the adhesion of dirt.

In addition, the sanitary washing device of the present invention may be provided with a remote controller for toilet washing, and the flush switch may be provided on the remote controller for toilet washing.

In addition, the sanitary washing device of the present invention may be equipped with a remote control, and the flush switch may be provided on the remote control.

This makes it easy to exchange with the newly purchased body. In addition, the control unit of the newly purchased body can be easily obtained through the toilet cleaning signal, and the integration with the remote control for toilet cleaning or the remote control can be easily obtained.

In addition, the spray nozzle of the sanitary washing device of the present invention is installed on the main body by inclining the rotation axis of the discharge port of the spray nozzle that is rotationally driven in the front-to-rear direction and the left-to-right direction. Furthermore, the inclination in the front-rear direction may be arranged with the lower side of the spreading nozzle inclined to the front side of the toilet with respect to the rotating shaft, and the inclination in the left-right direction may be arranged with the lower side of the spreading nozzle facing the washing nozzle side with respect to the rotating shaft. Tilt and configure.

According to this configuration, when the cleansing foam is spread to the toilet bowl of the toilet, when the discharge port of the dispersion nozzle is directed to the spreading position in front of the toilet, the direction of the discharge port is increased. On the other hand, when the discharge port of the dispersion nozzle is directed to the dispersion position behind the toilet where the distance is shortened, the direction of the discharge port becomes lower. Thereby, in accordance with the distance from the discharge port of the dispersion nozzle to the inner surface of the toilet, it is possible to spread the cleansing foam while changing the height of the discharge port of the dispersion nozzle. Therefore, it is possible to spread the washing foam on the inner surface from the front to the rear of the toilet and form a foam film. As a result, the adhesion of dirt to the inner surface of the toilet can be suppressed.

In addition, the control unit of the sanitary washing device of the present invention rotates the spray nozzle driving unit forward when rotating foam from the spray nozzle to the toilet, so that the direction of the spray nozzle of the spray nozzle passes from the back of the toilet to the front of the toilet.
