Hereinafter, the configuration of the water circuit of the sanitary washing device will be described with reference to Fig. 6 .

Fig. 6 is a schematic view showing the configuration of a water circuit of the sanitary washing device.

Further, the cleaning unit 500 constituting the water circuit shown in Fig. 6 is built in the main body 200 and washes a part of the user.

As shown in FIG. 6, the cleaning unit 500 is a nozzle device 800 that discharges at least the washing water, and a washing water supply flow path 690 that supplies the washing water to the nozzle device 800 from the water supply port 510. Composition.

A water supply connection port 510, a strainer 511, a check valve 512, a constant flow valve 513, a water stop solenoid valve 514, a relief valve 515, a sub tank 600, and a feed water supply flow path 690 are provided in this order. The heat exchanger 700, the buffer tank 750, the water pump 516 constituting the water discharge amount variable portion, the fluid regulating valve 517, and the like. Further, the washing water supply flow path 690 is finally connected to the nozzle device 800.

The water supply connection port 510 is disposed below the right side of the body 200 and is connected to, for example, an external water line. The strainer 511 is disposed inside the water supply connection port 510 to prevent the inflow of sand or the like contained in the tap water. The check valve 512 prevents water stored in the sub tank 600 from flowing back to the water line.

The constant flow valve 513 is disposed downstream of the check valve 512 to keep the amount of the washing water flowing to the washing water supply flow path 690 constant. The water stop solenoid valve 514 electrically switches the wash water supply flow path 690 according to the signal of the control unit 130. The constant flow valve 513 is integrally formed with the water stop solenoid valve 514 and the relief valve 515.

The sub tank 600 is disposed downstream of the water stop solenoid valve 514 and has an atmosphere opening port 603. The heat exchanger 700 can instantaneously heat the washing water to a set temperature. The buffer tank 750 forms the temperature of the warm water heated by the heat exchanger 700 to be uniform.

The water pump 516 constituting the water discharge amount variable portion is connected downstream of the buffer tank 750. The nozzle device 800 is disposed downstream of the water pump 516 and is coupled to the water pump 516 via a fluid regulating valve 517. Ports of the fluid regulating valve 517 are connected to the buttock washing nozzle 831, the genital washing nozzle 832, the nozzle cleaning portion 833, and the like of the nozzle device 800.

Further, as shown in FIG. 6, the branch flow path 530 is provided with an on-off valve 530a, and is disposed between the water pump 516 of the washing water supply flow path 690 and the fluid regulating valve 517. The branch flow path 530 connects the washing water supply flow path 690 and the bubble generating portion 560.

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

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

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

The air pump 535 sends air to the foam box 532 which has been supplied with the washing water and the lotion, and in the case of the lotion, a washing foam is generated. Further, the air pump 535 supplies the generated washing foam or washing water or the like from the foam tank 532 to the dispensing nozzle 550.

Further, as shown in FIG. 6, only one check valve 531 is provided on the branch flow path 530 which is branched between the water pump 516 and the fluid regulating valve 517. However, in actuality, in the foam tank water inlet portion 532a (refer to FIG. 26) where the washing water enters the foam tank 532 from the branch flow path 530, there is another rubber, for example, rubber which is different from the check valve 531 of FIG. Check valve 531b (duckbill, Duckbill). In other words, in the present embodiment, a plurality of check valves are provided on the upstream side of the water entering the foam tank 532. Thereby, a double-structured backflow prevention structure is formed to prevent the liquid or the washing foam in the foam tank 532 containing the lotion from flowing back to the tap water side, thereby improving safety.

Moreover, the broken line shown in FIG. 6 is a case where the control unit 130 is electrically connected to each component, and is controlled by the control unit 130. <3> Discharge control, action, and action on the inner surface of the toilet by a spray nozzle

Hereinafter, the discharge control, action, and operation of the inner surface of the toilet by the dispensing nozzle of the sanitary washing device will be described with reference to Figs. 7 to 12 .

Fig. 7 is a perspective view showing the appearance of a dispensing nozzle of the sanitary washing device. Fig. 8 is a longitudinal sectional view of the scattering nozzle. Fig. 9 is a vertical cross-sectional view showing an installation state of a dispensing nozzle in the sanitary washing device. Fig. 10 is a front elevational view showing the installation state of the dispensing nozzle in the sanitary washing device. Fig. 11 is a plan view showing the installation position of the scattering nozzle and the rotation angle of the discharge port of the dispensing nozzle in the sanitary washing device. Fig. 12 is a graph showing the output of the water discharge amount variable portion in the rotation angle of the discharge port of the discharge nozzle.

As shown in FIGS. 7 and 8, the scattering nozzle 550 is composed of a dispersion nozzle driving unit 550a, a main body 550c, a rotary nozzle 550d, and the like. The scattering nozzle driving unit 550a is configured by, for example, a motor, and rotationally drives the rotating nozzle 550d. The main body 550c includes an inlet flow path 550b and an inlet hole 550h, and supplies the washing foam, the washing water, and the like generated by the foam generating portion 560 shown in Fig. 6 to the rotary nozzle 550d. Further, the main body 550c rotatably holds the rotary nozzle 550d axially sealed by the O-ring 550e and the O-ring 550f. Further, an X-ring may be used instead of the above-mentioned O-ring 550f. Thereby, the torque required for the rotational driving of the rotary nozzle 550d can be reduced. Moreover, the fixation of the rotary nozzle 550d can be prevented more reliably. As a result, it becomes possible to use a small-sized, low-torque motor on the distribution nozzle drive unit 550a.

Further, the rotary nozzle 550d is rotatably driven by the shaft 550n so as to be fitted into the dispersion nozzle driving portion 550a.

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

First, the washing water or the washing foam generated by the foam generating portion 560 shown in Fig. 6 is supplied from the inlet flow path 550b of the main body 550c of the dispensing nozzle 550. The supplied washing water or washing foam is supplied into the rotary nozzle 550d from a plurality of inlet holes 550h that are cut around the rotary nozzle 550d. Thereafter, the supplied washing water or washing foam is discharged from the discharge port 550u of the rotary nozzle 550d toward the inner surface of the toilet 110 or the buttock washing nozzle 831.

As shown in FIGS. 10 and 11, the scattering nozzle 550 is disposed at the right side of the center of the body 200. The reason for this is that the washing nozzle (ie, the buttock washing nozzle 831 and the like) that washes the body part is preferentially placed in the center. Therefore, the scattering nozzles 550 are not disposed at the center but are disposed on one of the left and right sides. Furthermore, the above configuration may of course be reversed.

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

In the following, the discharge control in the rotary foam dispensing command issuing mode of the dispensing nozzle 550 in the case where the user is in the non-sitting state and the toilet seat is in the closed state will be described.

First, when the user enters the toilet, the control unit 130 of the sanitary washing device 100 detects the person's entry into the room by the human body detecting sensor 450. At this time, the control unit 130 sets a rotary foam dispensing command release (foam coating) mode in which the direction of the discharge port 550u of the dispensing nozzle 550 is rotationally driven, and the washing foam is dispersed in the toilet. Thereby, the control unit 130 is an operation that enters into the toilet 110 to perform a rotating foam dispersion. Further, the control unit 130 starts the operation of the water pump 516 shown in FIG. Further, the control unit 130 opens the opening and closing valve 530a of the branch flow path 530.

In this case, the fluid regulating valve 517 for switching the flow path of the buttock washing nozzle 831, the genital washing nozzle 832, the nozzle cleaning portion 833, and the like is in a closed state. Therefore, the washing water from the heat exchanger 700 is supplied to the scattering nozzle 550 through the branch flow path 530, the check valve 531 constituting the bubble generating portion 560, and the foam tank 532. The supplied washing water is discharged from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet or the buttock washing nozzle 831 or the like.

That is, the control unit 130 drives the scattering nozzle driving unit 550a of the dispensing nozzle 550 to rotate the discharge port 550u of the rotating nozzle 550d. At this time, the washing water or the washing foam discharged from the discharge port 550u is spread over the entire circumference of the inner surface of the toilet 110, the buttock washing nozzle 831, and the like to form a water film or a foam film. Thereby, the adhesion of dirt or the like to the inner surface of the toilet can be prevented.

Further, as shown in FIG. 11, the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet differs depending on the direction of the rotation angle of the dispensing nozzle 550.

In other words, when the rotation angle of the dispensing nozzle 550 disposed at the above position is changed, as shown in FIG. 11, when the rotation angle of the discharge port 550u of the dispensing nozzle 550 is 160°, the discharge port 550u is passed to the toilet. The distance from 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 a position rotated by 180° from the above 160°), the distance from the discharge port 550u to the inner surface of the toilet bowl is the shortest (near).

Therefore, as shown in FIG. 12, the control unit 130 controls the output of the water pump 516 constituting the water discharge amount variable portion to be changed in accordance with the rotation angle (distance) of the discharge port 550u of the dispensing nozzle 550.

Hereinafter, a method of controlling the output of the water pump 516 in response to the rotation angle of the dispensing nozzle 550 will be described.

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

At this time, as shown in FIG. 12, the control unit 130 discharges the discharge of the water pump 516 while changing the range from "high" to "low" in response to the rotation angle of the discharge port 550u of the dispensing nozzle 550. Net foam and so on.

Specifically, in the vicinity of the rotation angle 160° which is the longest (distal) rotation angle to the inner surface of the toilet shown in FIG. 11, the control unit 130 sets the output of the water pump 516 to be larger as shown in FIG. . On the other hand, the control unit 130 sets the output of the water pump 516 to be small in the vicinity of the shortest (near) rotation angle 340° to the inner surface of the toilet.

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

In addition, in FIG. 12, the operation of the dispersion nozzle 550 which has the rotation control part mentioned later is shown as an example. Therefore, it is displayed as a graph showing the change in the output of the water pump 516 in the range of the rotation angle of 0° to 340°. However, in the case where the rotation restricting portion is not provided, it is of course possible to change the output of the water pump 516 in a range in which the rotation angle is one rotation from 0° to 360°.

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

More specifically, when the washing foam and the washing water are discharged in front of the toilet located at the farthest distance from the discharge port 550u of the dispensing nozzle 550, the output of the water pump 516 is set to "medium" and is stronger. The force of the spit out the washing foam and washing water. Thereby, the washing foam and the washing water can be sufficiently supplied to the inner surface of the front side of the toilet.

On the other hand, when the washing foam and the washing water are discharged to the rear of the toilet located at the distance closest to the discharge port 550u of the dispensing nozzle 550, the output of the water pump 516 is set to "low" and discharged with the weakest force. Wash the foam and wash the water. Thereby, it is possible to prevent the occurrence of defects such as rebound of the washing foam and the washing water.

Further, a water film or a foam film is formed by previously discharging the washing water or washing the foam on the entire inner surface of the toilet bowl before use. Thereby, it is possible to suppress the adhesion of the dirt at the time of use to the inner surface of the toilet.

Further, in the present embodiment, when the human body detecting sensor 450 detects that the user enters the toilet or the user operates the dispensing switch 417 through the operation unit 210 or the remote controller 400, the control unit 130 will A so-called toilet foam spread in which the washing foam is previously scattered on the inner surface of the toilet is performed before use.

At this time, in the case where the toilet foam is dispersed, the control unit 130 changes the output of the water pump 516 constituting the water discharge amount variable unit in the toilet as shown in FIG. The surface is washed with a clean foam. Specifically, the control unit 130 firstly rotates the dispensing nozzle driving unit 550a (for example, in the clockwise direction) so as to move the direction of the discharge port 550u of the rotating nozzle 550d from the rear of the toilet to the front of the toilet and then to the rear of the toilet. Spread the wash foam on one side. Further, after that, the control unit 130 reverses the scattering nozzle driving unit 550a (for example, in the counterclockwise direction), and spreads the direction of the discharge port 550u of the rotating nozzle 550d while moving from the rear of the toilet to the front of the toilet and back to the rear of the toilet. Wash the foam. That is, the following steps are performed: the inner peripheral surface of the toilet is covered to rotate the discharge port 550u of the rotary nozzle 550d in the forward and reverse directions, and the washing foam is dispersed by at least one back and forth rotation.

At this time, the control unit 130 controls the output of the jetting amount variable portion so that the washing foam reaches the vicinity of the lip 110a of the toilet 110. Thereby, the washing foam can be dispersed on the inner surface of the toilet for almost the entire circumference (including the entire circumference) before use. As a result, a foam film can be formed on the inner surface from the front to the rear of the toilet, and the adhesion of the dirt can be suppressed if it does not occur.

In this case, as shown in FIG. 12, the control unit 130 preferably controls the output of the water discharge amount variable portion when the nozzle drive unit 550a is rotated forward to be lower than the output when the nozzle drive unit 550a is reversed. To spit out the wash foam.

Since the force for discharging the washing foam is weakened as long as the output of the water spouting variable portion is lowered, the washing foam can be spread to a closer position (position) by the dispensing nozzle. Specifically, as shown by the spread movement trajectory TF shown by the dotted line in Fig. 11, in the forward rotation (clockwise direction), the direction of the discharge port 550u of the rotary nozzle 550d is directed toward the lip 110a of the toilet 110. The wash foam is spread on the side of the inner side of the water surface 110b.

On the other hand, since the force for discharging the washing foam is increased as long as the output of the water spouting variable portion is increased, the washing foam can be spread to a distant place (position) by the dispensing nozzle. Specifically, as shown by the scattering movement trajectory TR shown by the dotted line in FIG. 11, in the reverse rotation (counterclockwise direction), the direction of the discharge port 550u of the rotary nozzle 550d is directed toward the lip 110a of the toilet 110. Wash the foam on the side.

Thereby, at the initial stage of the start of the dispersion (at the time of the forward rotation), first, the water surface 110b on the upper portion of the discharge port 115 of the toilet 110 can be covered by the washing foam. Thereafter, at the time of reversal, the washing foam can be spread over almost the entire circumference of the inner surface of the toilet 110 near the lip 110a. As a result, a foam film is formed on the water surface 110b from the front to the rear of the toilet and the inner surface from the water surface 110b to the lip 110a, and the adhesion of the dirt can be effectively suppressed.

Further, in the present embodiment, as shown in FIG. 2, FIG. 9, FIG. 10, FIG. 11, etc., the scattering nozzle 550 is disposed at a position in front of the main body 200 which is placed on the toilet 110. That is, the dispensing nozzle 550 is provided on the front side of the front end position in a state in which the nozzle device 800 is housed from the storage position of the washing nozzle 831 to the buttocks washing or the genital washing. The net position is used to clean the body. Thereby, at the time of rotational driving, the direction of the discharge port 550u of the rotary nozzle 550d can be directed toward the rear of the toilet 110, and the washing foam can be foamed. As a result, a foam film for washing foam can be formed on the inner surface from the front to the rear of the toilet 110, and the adhesion of the dirt can be suppressed.

In the above description, the configuration in which the output of the water pump 516 constituting the water discharge amount variable portion is changed when the rotating foam is dispersed in the toilet is controlled as an example, but the configuration is changed. Not limited to this. For example, when the rotating foam is dispersed, the output of the water pump 516 is not changed, and the dispensing nozzle 550 is configured as described below to form a foam film on the inner surface of the toilet to the rear to suppress the adhesion of dirt. .

At this time, as shown in FIG. 9 and FIG. 10, the rotation axis Ax of the dispersion nozzle 550 is inclined in the front-rear direction and the left-right direction, and is disposed in the main body 200. Specifically, the rotation axis Ax of the scattering nozzle 550 is disposed such that the scattering nozzle 550 faces downward and is inclined toward the front side of the toilet 110 in the front-rear direction. Further, the rotation axis Ax of the scattering nozzle 550 is also disposed such that the scattering nozzle 550 faces downward in the left-right direction and is inclined toward the cleaning nozzle 831 disposed at the center of the body 200. With the arrangement of the rotation axis Ax described above, when the discharge port 550u of the dispersion nozzle 550 is forward of the toilet 110 that is farther toward the scattering position, the position of the discharge port 550u becomes higher. Therefore, as shown in the discharge direction AcA of Fig. 9, the washing foam can be discharged in the horizontal direction. As a result, the washing foam can be spread to the vicinity of the lip 110a in front of the toilet 110.

On the other hand, when the discharge port 550u of the dispensing nozzle 550 is behind the toilet 110 that is closer to the scattering position, the position of the discharge port 550u is lowered. Therefore, as shown in the discharge port direction AcB of Fig. 9, the washing foam can be discharged in the obliquely downward direction.

Further, when the distance to the scattering position is on the right side of the toilet 110 which is gradually farther and the discharge port 550u is advanced from the rear toward the front, the direction of the discharge port 550u is gradually changed from the discharge port direction AcB toward the discharge port direction AcA. The ground becomes high. As a result, the washing foam can be dispersed along the vicinity of the lip 110a on the right side of the toilet 110. When the distance to the scattering position is on the left side of the toilet 110 that is gradually getting closer and the discharge port 550u is moving forward from the front, the direction of the discharge port 550u is directed from the discharge port direction AcA toward the discharge port direction AcB. And gradually become lower.

In other words, when the rotating foam is dispersed, the scattering nozzle driving unit 550a is rotationally driven about the rotation axis Ax so as to be dispersed in a direction in which the direction of the discharge port 550u of the rotary nozzle 550d is, for example, from the discharge port direction AcB to In the discharge direction AcB of the discharge direction AcA. At this time, as described above, the distance from the discharge port 550u to the inner surface of the toilet 110 is changed along with the rotation of the dispensing nozzle 550. However, by arranging the rotation axis Ax of the dispersion nozzle 550 to be inclined, the height of the discharge port 550u of the dispersion nozzle 550 can be changed and washed as indicated by the discharge direction AcA and the discharge direction AcB. Net foam. Therefore, the movement track TR can be spread along the left-handed dotted arrow in Fig. 11, and a foam film can be formed on the inner surface of the lip 110a from the front to the rear of the toilet 110. As a result, the entire inner surface from the front to the rear of the toilet 110 can be covered to suppress the adhesion of dirt.

According to the above configuration, when the rotary foam is dispersed, the output of the water pump 516 can be changed without changing the output of the water pump 516. Therefore, when the right-handed rotating foam is dispersed, it is also possible to advance and spread the washing foam in the opposite direction by using the same trajectory as the scattering movement trajectory TR indicated by the left-turning dotted arrow shown in FIG.

Further, in the present embodiment, the rotation axis Ax of the scattering nozzle 550 is such that the inclination angle β in the front-rear direction shown in Fig. 9 is, for example, 20 degrees, and the inclination angle in the left-right direction shown in Fig. 10 is made. γ is arranged, for example, at 10 degrees. Of course, the above angle may be arbitrarily changed in accordance with the shape of the toilet or the position at which the nozzle 550 is disposed.

Further, the height position of the discharge port 550u of the dispensing nozzle 550 is set to be lower than the upper end surface 110c of the toilet 110 at any rotational position.

In the above description, the forward rotation is a case where the right rotation is the rotation of the right rotation when viewed from above in FIG. 11, and the rotation is reversed to the left rotation, but the present invention is not limited thereto. For example, it is also possible to set the forward rotation to the left-hand rotation and the reverse rotation to the right-hand rotation. That is, the direction in which the discharge port 550u of the dispensing nozzle starts to rotate at the time of scattering is referred to as forward rotation, and the direction of return is referred to as reversal, and the direction of rotation is not particularly limited.

As described above, the control unit 130 changes the output of the water pump 516 in accordance with the rotation angle of the discharge port 550u of the dispensing nozzle 550. Thereby, the washing water or the washing foam can be discharged from the dispensing nozzle 550 to the front side, the side, and the rear of the inner surface of the toilet 110 having a different distance. 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 the dirt.

In the above embodiment, the configuration in which "high" and "low" are set based on the average level "middle" of the output of the water pump 516 will be described as an example, but the present invention is not limited thereto. For example, the average level "middle" of the output of the water pump 516 may be set to be higher or lower to change the reference level. At this time, it is preferable to provide a level change switch for adjusting the average level on the operation unit 210 or the remote controller 400. Thereby, even when the size of the toilet 110 of the sanitary washing apparatus 100 is different, the washing water or the washing foam can be discharged to the entire circumference of the inner surface of the toilet. Further, the height position (relative to the horizontal plane) of the washing foam dispersed on the inner surface of the toilet 110 may be arbitrarily changed. Thereby, a water film or a foam film can be formed at any position on the inner surface of the toilet 110, and the adhesion of dirt can be suppressed.

In the above-described embodiment, the control unit 130 is described as an example of the discharge control for changing the output of the water pump 516 in accordance with the rotation angle of the discharge port 550u of the dispensing nozzle 550. However, the present invention is not limited thereto. . For example, in addition to the change in the output of the water pump 516, the control unit 130 may control the rotation speed of the dispensing nozzle driving unit 550a to change in accordance with the rotation angle of the discharge port 550u.

That is, in the present embodiment, the output of the water pump 516 is changed, and the discharge force of the washing water or the washing foam is changed. Thereby, the washing water or the 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 dispensing nozzle 550 is rotated at a fixed rotational speed, the scattering density of the washing foam and the washing water becomes sparse when the distance to the inner surface of the toilet is far. On the other hand, the density of the washing foam and the washing water becomes denser when the distance to the inner surface of the toilet is relatively close.

Then, in the present embodiment, the rotation speed of the dispensing nozzle 550 may be changed by the nozzle driving unit 550a in response to the rotation angle of the discharge port 550u. Thereby, the entire circumference of the inner surface of the toilet 110 can be covered to spread the washing water or the washing foam at an equal spreading density.

Further, even when the output of the water pump 516 is changed to disperse the washing foam and the washing water, the scattering density of the washing foam and the washing water can be made equal to some extent.

However, when the washing speed of the dispensing nozzle driving portion 550a is changed in accordance with the rotation angle of the dispensing nozzle 550 to disperse the washing foam and the washing water, the scattering 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 at a more uniform spreading density.

That is, when the rotation speed is fixed, as shown in Fig. 11, the washing water or the washing is performed in the vicinity of the rotation angle of 160° which is the farthest distance from the discharge port 550u of the dispensing nozzle 550 (also before the device 110). The net foam will be dispersed to make the density of the distribution sparse. Therefore, when the washing foam and the washing water are discharged to the front of the toilet 110, the rotation speed of the dispensing nozzle 550 is set to be the slowest. Thereby, the time until the discharge port 550u of the dispensing nozzle 550 passes near the front of the toilet 110 becomes long. As a result, the scattering density of the washed foam can be increased.

On the other hand, when the rotation speed is fixed, the washing foam or the washing water which is discharged near the rotation angle of 340° which is the closest distance to the discharge port 550u of the dispensing nozzle 550 (and even after the device 110) may be collected. And the density of the dispersion is made dense. Therefore, the rotational speed of the dispensing nozzle 550 is set to be the fastest. Thereby, the time in which the discharge port 550u of the dispensing nozzle 550 passes near the rear of the toilet is shortened. As a result, the scattering density of the washed foam can be lowered.

That is, the distribution of the washing water or the washing foam dispersed on the inner surface of the toilet bowl can be equalized (the shading is eliminated) by the variable rotation speed. Therefore, by the formation of a non-uniform foam film, the entire circumference of the inner surface of the toilet can be covered, and the adhesion of the dirt can be more effectively suppressed.

As described above, the control unit 130 changes the rotational speed of the dispensing nozzle driving unit 550a in accordance with the rotation angle of the discharge port 550u of the dispensing nozzle 550. For example, when the direction of the discharge port 550u of the dispensing nozzle 550 is a rotation angle toward the front of the toilet bowl, the rotation speed of the scattering nozzle driving portion 550a is gradually reduced (lower speed). . On the other hand, when the direction of the discharge port 550u is a rotation angle toward the rear of the toilet bowl, the speed at which the nozzle drive unit is dispersed is gradually increased (higher speed). Thereby, the washing water or the washing foam can be uniformly discharged without unevenness in the density of the front side, the side, and the rear of the toilets having different distances. As a result, the adhesion of the dirt can be effectively suppressed by the water film or the foam film which is uniformly formed on the inner surface of the toilet bowl.

Further, in the present embodiment, the control unit 130 controls to discharge the washing water or the washing foam from the dispensing nozzle 550 to the inner surface of the toilet when the human body detecting sensor 450 detects the entry of the person. The so-called toilet foam is scattered. Specifically, the control unit 130 controls the rotation of the rotary nozzle 550d to rotate the rotary nozzle 550d at least once, for example, at least once, and automatically stops after the foam is dispersed. Thereby, a water film or a foam film can be formed in advance on the inner surface of the toilet before the user uses the sanitary washing device. As a result, the adhesion to the dirt on the inner surface of the toilet bowl at the time of use can be effectively suppressed.

In the above description, the washing nozzle 550 is rotated one time before and after the use, and the washing foam and the washing water are dispersed one by one, but the invention is not limited thereto. For example, the number of times that the scattered washing foam and the washing water can be sufficiently spread over the inner surface of the toilet can be any, and the number of times can be arbitrary. In this case, the number of round trips when the toilet foam is dispersed is preferably configured to be selectively set by the user via the operation unit 210 or the remote controller 400.

Further, in the above-described embodiment, the direction of rotation of the dispensing nozzle 550 is not particularly mentioned. As shown in Fig. 12, the rotary nozzle 550d is configured to rotate back and forth once. The reason for this is that, in a configuration in which the rotary nozzle 550d of the dispensing nozzle 550 is rotated all the way in either the right direction or the left direction, the direction in which the washing water or the washing foam is dispersed is often Become the same direction. Therefore, in the present embodiment, the washing foam or the washing water is spread to the inner surface of the toilet from the forward and reverse rotation directions by rotating back and forth once. Thereby, the occurrence of so-called scattered omissions can be further reduced. Therefore, it becomes possible to spread the washing foam and the washing water more evenly over the inner surface of the toilet. As a result, it is possible to suppress the adhesion of the dirt to the inner surface of the toilet with a small number of times (time). Furthermore, the above-mentioned back and forth rotation is not limited to one round trip, and may be set to two round trips or three times back and forth.

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

In this case, it is preferable to provide, for example, a mechanical stopper (ie, a rotation restricting portion) that limits the rotatable range of the rotary nozzle 550d of the dispensing nozzle 550 to a range of the rotation angle of 0° to the rotation angle of 340° (not The composition of the illustration).

Specifically, the rotation restricting portion is constituted by, for example, a projection formed on a part of the outer circumference of the rotary nozzle 550d and a rotation restricting wall of the main body 550c. According to this configuration, when the projection rotates and physically abuts against the rotation restricting wall, the movement of the rotary nozzle 550d to be rotated is restricted. That is, the motor constituting the scattering nozzle driving portion 550a is slid and idling by abutment. Thereby, the rotary nozzle 550d can restrict the rotation above the rotatable range.

As described above, the scattering nozzle 550 having the above-described configuration is provided with the rotation restricting portion for restricting the rotation range, and the scattering nozzle 550 can be rotated back and forth within the rotatable range that is not restricted by the rotation restricting portion. Further, the washing foam or the washing water is spread to the inner surface of the toilet from the direction of the forward and reverse rotation of the back and forth rotation. Thereby, the occurrence of so-called scattered missing parts is reduced. Therefore, it becomes possible to spread the washing foam and the washing water more evenly over the inner surface of the toilet. As a result, it is possible to form a foam film which can suppress adhesion of dirt to the inner surface of the toilet with a small number of times of dispersion (time).

Moreover, the control unit 130 can often recognize the position at which the projection of the rotary nozzle 550d of the scattering nozzle 550 and the rotation restricting portion abut on the origin of the rotational position of the nozzle driving unit 550a. Therefore, occurrence of the origin shift due to the back and forth motion of the rotary nozzle 550d can be prevented. Thereby, the positional accuracy of the rotation angle of the rotary nozzle 550d with respect to the inner surface of the toilet can be improved. That is, the deviation of the positional deviation or the like can be reduced with respect to the predetermined position of the inner surface of the toilet. As a result, the washing foam and the washing water can be dispersed by the discharge port 550u of the dispensing nozzle 550 at an appropriate position on the inner surface of the toilet with an appropriate discharge output and rotational speed.

In the above description, the configuration in which the rotation range of the dispensing nozzle 550 is physically limited is described as an example, but the configuration is not limited thereto. When the positional deviation of the origin of the dispensing nozzle 550 does not constitute a problem, the forward and reverse rotation of the dispensing nozzle 550 can be simply performed by the scattering nozzle driving unit 550a. Thereby, the rotation restricting portion is not required, and various operations of the rotary nozzle 550d such as forward/reverse rotation or unidirectional rotation can be performed. As a result, the rotary nozzle 550d can be more appropriately operated in response to the situation such as dirt on the inner surface of the toilet bowl. In this case, it is preferable to set the origin of the dispensing nozzle 550 to a rotation angle of 160° to be reversed, and to control the rotation speed to be gradually slowed in the vicinity. Thereby, the load applied at the time of the rapid reversal of the dispersion nozzle drive unit 550a can be reduced.

Hereinafter, the configuration of the foam generating portion 560 of the sanitary washing device of the present embodiment will be described with reference to Fig. 6 .

As shown in FIG. 6, the bubble generating portion 560 is connected to the branch flow path 530 through the switching valve 530a and the check valve 531, and the branch flow path 530 is a water pump 516 and a fluid regulating valve 517 which constitute the water discharge amount variable portion. The flow path between the washing water supply flow path 690 is different. Further, the opening and closing of the on-off valve 530a is performed to supply the washing water to the bubble generating portion 560 through the branch flow path 530.

The foam generating portion 560 is constituted by a check valve 531, a foam box 532, a detergent tank 533, a detergent pump 534, an air pump 535, and the like.

The foam box 532 is connected with a dispensing nozzle 550 downstream. The foam box 532 is connected to the detergent tank 533 which supplies the lotion through the lotion pump 534.

The foam box 532 is also coupled to the air pump 535. The air pump 535 sends air to the foam box 532 to cause it to be washed and the like. Moreover, the air pump 535 supplies the washing water and the generated washing foam to the dispensing nozzle 550.

As described above, the foam generating portion 560 can be configured and operated as follows.

First, the control unit 130 turns on the switching valve 530a. Then, the control unit 130 drives the water pump 516, and the washing water is sent to the foam tank 532 of the bubble generating portion 560 by the heat exchanger 700. At this time, in the foam tank 532, the lotion supplied from the detergent tank 533 by the detergent pump 534 and the washing water supplied from the heat exchanger 700 are mixed.

Next, the control unit 130 drives the air pump 535 to supply air into the foam tank 532. Thereby, a washing foam is generated in the foam box 532. The generated washing foam is supplied to the dispensing nozzle 550, and is discharged to the inner surface of the toilet by the discharge port 550u of the rotary nozzle 550d.

At this time, depending on the increase or decrease of the output of the water pump 516 and the air pump 535, the discharge amount of the washing water or the washing foam discharged from the dispensing nozzle 550 and the force of the discharge (the discharge speed and the discharge) are increased or decreased. Pressure). Thereby, the washing foam and the washing water can be uniformly distributed on the inner surface of the toilet as in the case described with reference to Fig. 11 . In other words, the air pump 535 of the bubble generating portion 560 also functions as the water discharge amount variable portion in the same manner as the water pump 516.

In the above description, the configuration in which the switching valve 530a is provided in the branch flow path 530 will be described as an example, but the present invention is not limited thereto. For example, a configuration may be adopted in which a flow path switching valve is provided in a branch portion of the branch flow path 530 and the washing water supply flow path 690.

That is, the foam generating portion 560 of the present embodiment includes the foam box 532 between the opening and closing valve 530a and the dispensing nozzle 550. The foam box 532 is supplied with a lotion from the detergent tank 533 and generates a wash foam. The generated cleaned foam is configured to be discharged from the discharge port 550u of the dispensing nozzle 550 toward the inner surface of the toilet.

Thereby, the inner surface of the toilet is not only a water film formed by the dispersion of water or warm water, but also a foam film formed of a washing foam containing a lotion. As a result, the adhesion of the dirt to the inner surface of the toilet can be more effectively suppressed.

Moreover, the odor generated by dirt or the like can be effectively suppressed by the washing foam containing the lotion. In addition, the wash foam imparts a visually clean impression to the user. As a result, the user's comfort is further enhanced.

Furthermore, in the above-described embodiment, the configuration in which the human body detecting sensor 450 detects the entry of a person, that is, the configuration in which the washing water or the washing foam on the inner surface of the toilet is dispersed is described as an example. Not limited to this. For example, it is also possible to form a configuration in which the distribution switch 417 provided in the operation unit 210 or the remote controller 400 is operated by a person. Thereby, even when the toilet as the sanitary washing device is not used, it is possible to remove the dirt by dissolving the washing foam or the like containing the lotion on the inner surface of the toilet when the dirt on the inner surface of the toilet is concerned. Further, it is possible to prevent the formation of stubborn dirt on the surface 110b or the like due to drying when it does not occur. That is, by the user operating the spreading switch 417, the foam film formed by the washing foam containing the 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.

Further, in the above-described embodiment, the user may arbitrarily select one of the washing water and the washing foam on the inner surface of the toilet by using the operation selection unit (not shown) of the operation unit 210 or the remote controller 400 in advance. Composition. Thereby, it is possible to arbitrarily select whether or not the scattering is required depending on the state of the dirt on the inner surface of the toilet or the occurrence of odor or the like. As a result, the unnecessary use of the lotion can be suppressed, and the performance cost performance can be improved.

Further, in the above-described embodiment, the control unit 130 may be configured to have a washing command issuing mode in which an instruction can be selected by the operation button 210 or the on/off button of the remote controller 400.

In this case, in the washing instruction issuing mode, the control unit 130 first opens in a state where the lotion which can stop the detergent tank 533 of the foam generating portion 560 is supplied to the detergent pump 534 of the foam tank 532. Switch valve 530a. Thereby, the water pump 516 delivers the washing water to the foam tank 532. The supplied washing water is supplied from the foam tank 532 to the dispensing nozzle 550, and is discharged into the toilet 110.

At this time, the path from the foam tank 532 to the dispensing nozzle 550 is first washed by the washing water. Thereby, in the case where the washing agent remains in the path or the dispensing nozzle 550, it is possible to wash it in advance by washing the water. Therefore, it is possible to prevent the path or the clogging of the dispensing nozzle 550 due to the fixing of the lotion, and the rotation failure condition of the dispensing nozzle 550. Further, the inner surface of the toilet bowl can be washed with washing water in advance.

That is, the detergent pump 534 is in a stopped state during the washing operation in the washing instruction issuing mode. Therefore, the lotion is not supplied to the foam tank 532, and only the washing water is supplied. Thereby, the path from the foam tank 532 to the dispensing nozzle 550 is washed by the supplied washing water. At the same time, the washing water that has washed the path is scattered from the dispensing 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.

Further, in the washing operation in the washing instruction issuing mode, washing is usually performed by washing water which is not controlled by temperature. However, the temperature of the washing water may be further supplied by heating the heat exchanger 700 to, for example, about 40 ° C to perform a washing operation. Thereby, the solubility of the residual lotion etc. in washing water can be improved, and a more excellent washing effect can be obtained.

Further, in the washing command issuing mode, the user can arbitrarily perform the washing of the path or the inner surface of the toilet by the operation of the washing switch 223 of the operating unit 210.

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 in the washing command issuing mode. Further, the control unit 130 causes the washing lamp 223a to automatically blink when a predetermined time such as 20 days elapses after the previous washing is performed. Thereby, it is possible to prevent forgetting to wash, and it is possible to prevent the occurrence of clogging such as a route.

Further, when the washing foam is scattered on the inner surface of the toilet, the control unit 130 can also make the air assist in accordance with the rotation angle of the discharge port 550u of the dispensing nozzle 550, similarly to the output operation of the water pump 516 shown in Fig. 12 . The output of the 535 is changed to spread the foam from the spout 550u. Thereby, the washing foam can be discharged to be effectively delivered to the front, the side, and the rear of the toilets having different distances. As a result, a foam film can be integrally formed on the inner surface of the toilet to suppress the adhesion of dirt.

Specifically, as explained with reference to FIG. 11, the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet is the longest (distal) rotation angle of 160°, and the control unit 130 will drive the air pump 535. The output (air pressure) is set larger (higher). Thereby, the air pressure caused by the air pump 535 can be increased, and the force for flying the cleaning foam from the discharge port 550u to the far side can be enhanced.

On the other hand, in the vicinity of the rotation angle 340A where the distance from the discharge port 550u to the inner surface of the toilet is the shortest (near), 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 lowered, and the force for flying the cleaning foam can be weakened.

That is, the air pressure discharged from the air pump 535 is adjusted in response to the distance from the discharge port 550u of the dispensing nozzle 550 to the inner surface of the toilet. As a result, the cleaned foam can be spit out of the inner surface of the toilet without any omission.

Further, in the above-described embodiment, a dirt detecting unit (not shown) that detects the dirt of the toilet with an image element such as a CCD (Charge Coupled Device) may be provided. At this time, the control unit 130 drives the scattering nozzle 550 to move back and forth in the portion where the dirt remains, according to the detection result of the dirt detecting unit, and concentrates the washing foam in a concentrated manner. Thereby, the dirt adhering to the inner surface of the toilet can be effectively removed. Further, in addition to the method of returning only to the dirt portion, the rotation speed of the discharge port 550u of the scattering nozzle 550 passing through the dirt portion may be rotationally driven at a lower speed. Further, it is also possible to form a configuration in which the output of the water pump 516 or the air pump 535 is further increased when passing through the dirt portion. The same effect can be obtained by this. <4> Discharge control, action, and action by the dispensing nozzle in the open seat and non-sitting state

Further, in the item <3>, it is explained that the direction of the discharge port 550u of the dispensing nozzle 550 is rotationally driven according to the rotary foam dispensing command release (foam coating) mode of the control unit 130, and the foam is washed. The rotating foam scattered in the toilet is scattered.

In the item <4>, the fixed foam distribution command is issued (splash suppression) mode in the control unit 130, and the washing foam is dispersed into the toilet as it is in the direction in which the discharge port 550u of the dispensing nozzle 550 is fixed. .

That is, the fixed foam dispersion in a state in which the user is not seated in the toilet seat 300 and the toilet seat 300 is opened almost vertically is described for the case of a male urination.

Specifically, the discharge control of the dispensing nozzle in the fixed foam dispensing command issuing mode in the case where the user operates the manual splash suppression switch 434 as the dispensing switch will be described with reference to FIGS. 13A and 13B.

Fig. 13A is an explanatory view showing the output of the water pump in the discharge operation of the inner surface of the toilet by the dispensing nozzle. Fig. 13B is an explanatory view showing the discharge direction of the inner surface of the toilet of the dispensing nozzle.

At this time, since the user is in the standing posture, the toilet seat 300 is in the opened state. That is, the toilet seat switch detecting portion 331 detects the toilet seat open state, and the seat detecting portion 330 detects the non-seat state.

In the above state, the user is the manual splash suppression switch 434 that presses the operation unit 210 or the remote controller 400. Further, the manual splash suppression switch 434 of the operation unit 210 is not particularly illustrated.

Thereby, the control unit 130 first drives the scattering nozzle driving unit 550a, and as shown in FIG. 13B, rotates the direction of the discharge port 550u of the dispensing nozzle 550 to a position facing the rear of the toilet. Next, the driving of the discharge nozzle driving portion 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, for example, a position near 20 degrees. Thereby, the direction of the discharge port 550u is directed 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 constituting the water discharge amount variable portion to be "high" output. Then, the washing water or the washing foam is discharged from the dispensing nozzle 550 toward the rear of the toilet 110 in a direction indicated by an arrow in FIG. 13B for a predetermined time. In the present embodiment, the predetermined time is set to, for example, 8 seconds.

At this time, the discharge port 550u of the dispersion nozzle 550 is stopped in the direction of the downward angle α toward the rear with respect to the rotation axis Ax of the dispersion nozzle 550 shown in Fig. 9 . Therefore, the washing foam or the like is discharged from the discharge port 550u of the dispensing nozzle 550 in a state of being stopped in the direction indicated by the discharge port direction AcB in Fig. 9 .

That is, after the rotation of the discharge port 550u of the dispensing nozzle 550 is rotationally driven to the rear of the toilet, the control unit 130 controls the water pump 516 to the "high" output to discharge the washing foam or the like. As a result, the washing foam quickly flows down from the rear side, and becomes a state in which the upper surface of the discharge port 115 in the toilet bowl and the upper portion of the water line in the toilet are quickly covered with the washing foam. As a result, it is possible to suppress the spread of the odor accompanying the excretion of urination or the like and the adhesion of the dirt near the draft surface 110b of the toilet 110 by the washing foam.

Further, when the discharged urination falls near the water surface in the toilet 110, the washing foam covering the water surface can serve as a cushioning effect. Thereby, it is possible to suppress the rebound of the periphery of the toilet 110. That is, a large amount of the washing foam or the like is quickly spread in the direction in which the nozzle 550 is fixedly dispersed to form a foam film on the upper surface of the water in the toilet 110. Thereby, it is possible to prevent the urine from escaping outside the toilet 110 due to bounce or the like.

In the present embodiment, when the fixed foam dispensing command issuing mode (splash suppression mode) is set by the operation of the manual manual splash suppression switch 434, the discharge port 550u faces the rear side of the toilet. At the position, the rotational driving of the nozzle driving portion 550a is stopped. Although the control unit 130 controls the water discharge amount variable unit 516 to output the washing foam toward the rear of the toilet with the "high" output, the control unit 130 is not limited thereto. For example, the position of the dispensing nozzle 550 in which the washing foam is fixedly dispersed may be any one of the front side, the center, the rear side, or the left and right sides of the toilet near the discharge port 115 of the toilet 110. In other words, as long as it is possible to discharge the washing foam, the washing surface 110b and the upper portion of the water line of the toilet 110 can be quickly covered with the washing foam for a short time, for example, for a short time. Thereby, splashing or scattering of urine can be suppressed. Further, it is possible to more reliably suppress the adhesion of the dirt to the vicinity of the water line in the toilet 110 and the upper portion thereof.

Further, in the present embodiment, the control unit 130 discharges the washing foam from the jetting amount variable portion 516 toward the toilet rear side with a "high" output as shown in Fig. 13A in the fixed foam dispensing command issuing mode. The composition is exemplified, but is not limited thereto. For example, the output of the spouting amount variable unit 516 may be discharged with a "medium" output.

As described above, the sanitary washing apparatus of the present embodiment includes the main body 200 provided on the toilet 110, the washing nozzle 831 for washing the human body, the foam generating portion 560 for generating the washing foam, and the washing water to the inner surface of the toilet or The dispensing nozzle 550 for washing the foam and the jetting amount variable portion 516 for changing the flow rate of the washing water sent to the dispensing nozzle. Further, the sanitary washing device further includes a dispensing nozzle driving unit 550a that drives the discharge port 550u that disperses the nozzle, an opening and closing valve 530a that opens and closes the water passage to the dispensing nozzle, a control unit 130, and an operation unit 210 that instructs the control unit to set the control unit 210. . Further, the control unit 130 includes a control operation of rotating the foam dispensing command issuing mode, rotationally driving the direction of the discharge port 550u of the dispensing nozzle, and dispersing the washing foam into the toilet; and fixing the foam dispensing command issuing mode. When the direction of the discharge port 550u of the dispensing nozzle is fixed, the washing foam is dispersed into the toilet as it is.

According to this configuration, when the toilet foam is dispersed in the rotary foam dispensing command issuing mode, the control unit 130 rotationally drives the direction of the discharge port 550u of the dispensing nozzle and spreads the washing foam from the dispensing nozzle 550 into a wide range in the toilet. service. Thereby, the foam film is formed by washing the foam from the front surface to the rear of the toilet, and the adhesion of the dirt to the inner surface of the toilet and the vicinity of the water line can be suppressed.

On the other hand, when the toilet foam is dispersed in the fixed foam dispensing command issuing mode, the control unit 130 spreads the washing foam as it is in the state in which the discharge nozzle 550u of the dispensing nozzle is fixed. Moreover, a foam film for washing foam is formed rapidly on the upper surface of the water in the toilet. Thereby, the foam film of the washed foam can be used to quickly cover the water surface of the upper portion of the discharge port in the toilet. As a result, it is possible to suppress the scattering of the odor during urination or the scattering caused by the rebound from the water surface when the urine of the male is urinating by the buffering effect of the washed foam.

Here, the effect of suppressing the scattering of urine formed by washing the foam will be described with reference to the verification result shown in FIG.

Fig. 25 is a view showing the result of verification of the splash suppressing effect of the foam dispersion in the fixed foam dispensing command issuing mode of the sanitary washing device. The vertical axis of Fig. 25 shows the height (thickness) of the washing foam covering the water surface, and the horizontal axis shows the elapsed time.

As is apparent from the results shown in Fig. 25, first, the foam height of the washed foam decreases as time passes. Further, it can be seen that the foam height is about 5 mm or more at the initial stage of the scattering, and the scattering of urine or the like can be suppressed as compared with the case where there is no foam.

In addition, when the foam height is about 10 mm or more at the initial stage of the scattering, the effect of suppressing the scattering of urine from the potty surface of the toilet 110 to the outside becomes remarkable. In this case, it can be known that the suppression effect is also lowered as time passes.

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

According to the above verification result, the height of the foam on the water surface in the toilet formed by the foam dispersion is preferably 5 mm or more and the upper limit is 50 mm or less. In particular, a range of 10 mm to 50 mm or less is more preferable. Further, the 50 mm set as the upper limit is a value which is defined by the height of the foam of the buttocks when the user has seated on the toilet seat in the sanitary washing device used in the verification test. Therefore, in the different sanitary washing apparatuses, of course, the setting of the upper limit can be changed according to the size and shape of the toilet and the toilet seat.

In the sanitary washing apparatus of the present embodiment, the rotation axis Ax of the discharge port 550u of the rotary nozzle 550d of the scattering nozzle 550 that is rotationally driven is inclined in the front-rear direction and the left-right direction, and is provided in the main body 200. Further, the inclination in the front-rear direction is such that the lower side of the dispensing nozzle 550 is inclined toward the front side of the toilet 110 with respect to the rotation axis Ax, and the inclination in the left-right direction is to wash the lower side of the dispensing nozzle 550 with respect to the rotation axis Ax. The nozzle 831 side is inclined and arranged.

According to this configuration, when the toilet foam is dispersed in the toilet 110, when the discharge port 550u of the dispensing nozzle 550 is directed to the scattering position in front of the toilet that is farther away, the direction of the discharge port 550u is made. Becomes high. On the other hand, when the discharge port 550u of the dispensing nozzle is directed to the scattering position behind the toilet which is closer to the distance, the direction of the discharge port 550u is lowered. Thereby, it is possible to disperse the washing foam while changing the height of the discharge port 550u of the dispensing nozzle in response to the distance from the discharge port 550u of the dispensing nozzle to the inner surface of the toilet. Therefore, the washing foam can be spread to the inner surface to the rear of the toilet and the foam film can be formed without changing the output of the water pump 516. As a result, adhesion of dirt to the inner surface of the toilet can be suppressed.

Further, in the sanitary washing apparatus of the present embodiment, when the toilet 110 is rotated and foamed from the dispensing nozzle 550, the control unit 130 causes the dispensing nozzle driving unit 550a to rotate forward so that the direction of the discharge port 550u passes from the rear of the toilet. Rotate the front of the toilet to the rear of the toilet. Thereafter, the control unit 130 reverses the scattering nozzle driving unit 550a so as to rotate the direction of the discharge port 550u so as to pass from the rear of the toilet to the front of the toilet and return to the rear of the toilet. That is, the control unit 130 is a step operation of controlling the rotation of the rotating foam by at least one back and forth rotation.

According to this configuration, first, the control unit 130 causes the dispensing nozzle driving unit 550a to rotate forward, and spreads the washing foam while moving the direction of the discharge port 550u of the dispensing nozzle from the rear of the toilet to the rear of the toilet. Thereafter, the control unit 130 reverses the scattering nozzle driving unit 550a, and distributes the washing foam while moving the direction of the discharge port 550u toward the rear of the toilet from the rear of the toilet and returning to the rear of the toilet. That is, the direction of the discharge port 550u of the dispensing nozzle 550 is rotationally moved in the forward and reverse directions along the inner peripheral surface of the toilet, and the washing foam is dispersed by at least one back and forth rotation drive. At this time, the output of the spouting amount variable portion 516 is controlled so as to be able to reach the vicinity of the lip of the toilet 110, and the washing foam is spread over almost the entire circumference of the inner surface of the toilet. Thereby, a foam film can be formed from the front surface to the rear of the toilet, and the adhesion of dirt can be suppressed.

Further, the sanitary washing device of the present embodiment further includes a human body detecting sensor 450 that detects the user's entry and exit into the toilet. When the human body detecting sensor 450 detects that the user enters the toilet, the control unit 130 performs a rotating foam spread on the inner surface of the toilet by at least one back and forth rotation.

According to this configuration, when the human body detecting sensor 450 detects the user's entry into the toilet, it is possible to perform at least one back and forth rotational driving of the discharge port 550u of the dispensing nozzle to spread the inner surface of the toilet. The rotating foam of the washed foam is scattered. Thereby, a foam film can be formed in advance on the inner surface of the toilet before use to suppress the adhesion of the dirt when it does not occur.

Further, the sanitary washing apparatus of the present embodiment includes the foam tank 532 that transports the washing water by the jetting amount variable portion 516 by opening the opening and closing valve 530a by the control unit 130, and supplies the lotion of the washing tank 533 to the foam. The lotion pump 534 of the tank 532 and the air pump 535 that supplies air to the foam box. Further, the control unit 130 controls the discharge of the washing water or the washing foam of the foam tank 532 from the dispensing nozzle 550.

According to this configuration, not only water or warm water is discharged to the surface of the washing nozzle 831 or the inner surface of the toilet, but also the washing foam containing the lotion can be discharged. Thereby, the effect of washing and the effect of suppressing adhesion of dirt can be improved. Further, the diffusion of the odor can be suppressed by the washing foam containing the lotion. As a result, it is possible to provide the user with a visually clean feeling and a feeling of comfort during use.

Moreover, the control unit 130 of the sanitary washing apparatus of the present embodiment has a washing instruction issuing mode. Further, in the washing instruction issuing mode, the control unit 130 opens the opening and closing valve 530a in a state where the washing agent 533 of the washing tank 533 of the foam generating portion 560 is stopped and supplied to the detergent pump 534 of the foam tank 532. The water discharge amount variable portion 516 transports the washing water to the foam tank 532 and discharges it from the dispensing nozzle 550.

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

In the present embodiment, the configuration in which the motor is used as the dispersion nozzle driving unit 550a will be described as an example, but the invention is not limited thereto. It is also possible to form a configuration in which the discharge nozzle 550 is rotated by the reaction when the washing foam is discharged from the discharge port 550u of the dispensing nozzle 550. Thereby, the configuration can be simplified and power consumption can be suppressed.

Further, in the present embodiment, the configuration in which the scattering nozzle 550 is one is described as an example, but the invention is not limited thereto. For example, it is also possible to provide a configuration in which a plurality of scattering nozzles are provided in the form of a dispensing nozzle that disperses the washing foam near the lip 110a of the toilet 110, and a dispensing nozzle that disperses the washing foam near the discharge port 115 of the toilet 110. Wait. At this time, a plurality of scattering nozzles can be independently rotated, or they 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 the present embodiment, the configuration in which the discharge nozzle 550 is provided with one discharge port 550u is described as an example, but the present invention is not limited thereto. For example, the dispensing nozzle 550 may be provided with a plurality of discharge ports, such as a discharge port for distributing the cleaning foam in the vicinity of the lip 110a of the toilet 110, and a discharge port for discharging the washing foam in the vicinity of the discharge port 115 of the toilet 110. Thereby, the washing foam can be spread on the inner surface of the toilet in a short time.

Further, in the present embodiment, the configuration in which the dispensing nozzle 550 spreads the cleaning foam in the vicinity of the lip 110a of the toilet 110 and the vicinity of the discharge port 115 of the toilet 110 is described as an example, but is not limited. herein. For example, in addition to the above, a configuration may be further adopted in which the cleaning nozzle 550 disperses the washing foam at an intermediate position (height) between the lip 110a of the toilet 110 and the discharge port 115. Thereby, the occurrence of the scattered missing portion can be further reduced.

Moreover, as shown in FIG. 10, FIG. 14, and FIG. 15, the sanitary washing apparatus of this embodiment is equipped with the cuff cover 250 integrally provided in the side part of the main body 200 so that it may protrude toward the front. The cuff cover 250 has a cuff cover 217 that is disposed further forward than the operation unit 210 disposed on the upper portion, and a detergent tank 533 that is formed of a viewable container that is built in the front of the cuff cover 217 and that is inside the cuff cover 217. . Further, the cuff cover 250 is provided with a lotion level confirmation window 216 on the front side for confirming the position of the lotion level of the detergent tank 533.

According to this configuration, the user can easily confirm the remaining amount of the lotion liquid by visual means during use of the sanitary washing device or the like. Therefore, the lotion can be replenished before the lotion solution is used up.

That is, the detergent tank 533 has a lotion injection port 537 in which the detergent tank cap 536 is provided. The detergent tank 533 is disposed at the forefront of the front side of the operation portion 210 of the cuff cover 250, and is disposed at a position closest to the front of the toilet. Therefore, the replenishment of the lotion liquid becomes easy. Further, the sleeve cover 217 is provided in front of the operation unit 210. Thereby, when the user replenishes the lotion liquid to the detergent tank 533, the user can prevent the washing liquid from falling on the operation unit 210. Further, as shown in FIGS. 14 and 15 , the lotion injection port 537 is disposed at a position lower than the operation unit 210 . Thereby, it is possible to more reliably prevent the washing agent from spilling on the operation portion 210 when the lotion liquid is replenished to the detergent tank 533.

Further, the sanitary washing device of the present embodiment is constituted by a tube composed of a cylindrical tube having a hollow inside and a double hose formed by further covering the tube on the outer side thereof to form a lotion pump shown in Figs. 6 and 14 . Hose 561. Further, the inner diameter of the lottery pump hose 561 is set to be thinner than the inner diameter of the foam tank hose 562.

With these configurations, even if a high pressure is applied from the lottery pump 534 to the lotion hose 561, the swelling and rupture of the lotter pump hose 561 can be prevented. Thereby, it is possible to stably spread the washing foam from the dispensing nozzle 550 into the toilet.

Further, the lotion pump hose 561 is constituted by, for example, a double tube in which an outer side of an elastomer resin tube is covered with a heat shrinkable tube, but the material is not limited thereto. In other words, it is not particularly limited as long as it is a material that can prevent expansion and breakage of the lottery pump hose 561 by a double tube structure. Thereby, the washing foam can be stably scattered from the dispensing nozzle 550.

Further, as shown in FIG. 2, FIG. 15, and FIG. 16, the sanitary washing apparatus of the present embodiment includes a control unit 130, a dispensing nozzle 550, a nozzle device, and the like in the interior of the main body 200, and the main body 200 is a main body casing. 202 covers the front of the rear body casing 201. Further, the dispensing nozzle 550 is disposed at a front portion of the rear body casing 201, and the front and upper portions of the dispensing nozzle 550 are covered by the body casing 202. Moreover, the discharge port 550u of the lower part of the dispersion nozzle 550 is provided in the form of opening to the inner surface of a toilet.

The above embodiment will be specifically described with reference to Fig. 16 .

Fig. 16 is a cross-sectional view showing the center portion of the dispensing nozzle 550 provided in the rear body casing 201 cut in the front-rear direction.

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

However, in the case of washing in the above-described washing command issuing mode, the washing water which has not washed the foam is discharged from the discharge port 550u of the dispensing nozzle 550. In this case, there is a fear that the jet flow of the washing water spreads and scatters as indicated by the two-dot chain line S in Fig. 16 . Therefore, there is a possibility that the washing water will fly to the outside of the toilet and the wet floor of the toilet will be wet.

Therefore, in the present embodiment, as shown in Fig. 16, a scattering guard portion 550z is provided on the main body casing 202. The scattering prevention portion 550z intercepts the jet flow from the discharge port 550u of the dispensing nozzle 550 and the washing water or the like in the upward direction exceeding the upper limit (flying out to the outside), and drops it into the toilet. Thereby, it is possible to prevent the washing foam and the washing water discharged from the dispensing nozzle 550 from being discharged to the outside of the toilet, and to spread the contents into the toilet.

In addition to the above-described scattering prevention function such as the above-described washing water, the scattering prevention unit 550z has a function described below with reference to FIGS. 17 to 18.

Figure 17 is a front elevational view of the body of the sanitary washing device. Figure 18 is a side elevational view of the body of the sanitary washing device. Further, the two-dot chain line shown in FIGS. 17 and 18 corresponds to a mounting surface of a pedestal or the like in the case where the main body 200 is placed.

The main body 200 of the sanitary washing device of the present embodiment is detachably attached to the toilet 110 through the main body fixing plate 240 shown in FIG.

That is, the body 200 is removed from the toilet 110, placed on the pedestal, etc., when the industrializer or the first installation of the toilet is used, or when the dirt near the lower portion of the body 200 is cleaned. The body 200 that has been removed may, for example, be temporarily placed on the pedestal or on the floor.

At this time, the scattering guard portion 550z protects the discharge port 550u of the dispensing nozzle 550 located below the mounting surface of the main body 200 from being placed in contact with the temporarily placed pedestal or floor. Thereby, the damage of the dispensing nozzle 550 can be prevented. That is, as shown in FIGS. 17 and 18, by the scattering guard portion 550z, the contact between the discharge port 550u of the dispensing nozzle 550 and the pedestal can be prevented by the scattering guard portion 550z.

Further, in the above-described embodiment, the configuration in which the scattering guard portion 550z is formed in the main body casing 202 has been described as an example, but the present invention is not limited thereto. For example, the scattering guard portion 550z may be formed in the main body 550c of the dispensing nozzle 550 or the like. Thereby, a complicated large-sized molding die at the time of molding the body casing 202 becomes unnecessary, and the body casing 202 can be molded by a simple molding die. Further, the discharge port 550u and the scattering guard portion 550z can be configured with high positional accuracy.

Next, a configuration in which the main body 200 is detachably attached to the toilet 110 will be described with reference to FIG.

Figure 19 is a perspective view of the body fixing plate 240 of the sanitary washing device and the rear body casing 201 of the body 200. In addition, for convenience of explanation, FIG. 19 is a state in which the control unit 130, the dispensing nozzle 550, the nozzle device, and the like provided inside are omitted.

In other words, the mounting bolt (not shown) is inserted into the position adjusting long hole 241 of the main body fixing plate 240, and the main body 200 is fixed to the toilet 110.

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

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

On the other hand, in the case where the main body 200 is removed from the toilet 110, the main body drop button 242 located beside (side) of the main body 200 shown in Fig. 19 can be pressed deep into the interior (for example) with a finger or the like. . Further, the main body 200 is pulled forward while being pushed in. Thereby, the body 200 can be removed from the toilet 110.

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

Further, as shown in FIG. 19, a magnet 243 is embedded in a resin main body fixing plate 240 such as polypropylene (PP), and a detachable sensor 244 is attached to the rear body casing 201. Thereby, the loading and unloading state of the body 200 and the toilet 110 can be detected.

Further, the loading and unloading sensor 244 is constituted by, for example, a reed switch.

Hereinafter, the detection of the loading and unloading state of the loading and unloading sensor 244 will be described using FIG.

Fig. 20 is a partial cross-sectional view showing a state in which 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 attached to the toilet 110, the magnet 243 of the main body fixing plate 240 and the attaching and detaching sensor 244 of the rear main body casing 201 are disposed in a positional relationship in which they face each other. . At this time, the reed switch as the attaching and detaching sensor 244 is turned on (ON) by the magnetic force of the magnet 243. Thereby, it is possible to detect that the body 200 has been mounted on the toilet 110.

On the other hand, when the body 200 is removed from the toilet 110, the magnet 243 is separated from the loading and unloading sensor 244, and the reed switch is turned OFF. Thereby, the loading and unloading sensor 244 can be used to detect the situation in which the body 200 and the toilet 110 are in the removed state.

Further, in the sanitary washing device of the present embodiment, when the attaching and detaching sensor 244 detects that the main body 200 is removed from the toilet 110, the control unit 130 controls the discharge operation of the dispensing nozzle 550 not to be performed. Therefore, in a state where the body 200 has been removed from the toilet 110, even if the user presses, for example, the manual foam application switch 433 or the manual splash suppression switch 434 of the remote controller main body 401, the control unit 130 does not perform the dispersion. The discharge operation of the nozzle 550 is performed. Thereby, it is possible to prevent the washing water or the washing foam from being accidentally sprayed toward the floor or the person.

On the other hand, even when the attaching and detaching sensor 244 detects that the main body 200 is removed from the toilet 110, the control unit 130 controls the discharge operation of the buttock washing nozzle 831 and the genital washing nozzle 832 not to be prohibited. This is because if the loading and unloading sensor 244 fails, the control unit 130 may mistakenly recognize that the main body 200 has been removed from the toilet 110. Then, the control unit 130 controls the buttock washing and the genital washing as 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 loading and unloading state of the loading and unloading sensor 244.

Hereinafter, the operation and control of each portion when the rotary foam is dispersed in the sanitary washing device of the present embodiment will be described with reference to Fig. 21 .

Fig. 21 is a timing chart showing the dispersion of the rotating foam in the sanitary washing device.

As shown in FIG. 21, at the time point N1, the user presses the manual foam application switch 433 of the remote controller main body 401. Thereby, the control unit 130 reverses the lottery pump 534 at the time point N3 after the detergent pump 534 is reversed, for example, for 2 seconds at the time point N2. At the same time, the control unit 130 starts the operation of the water pump 516 and the air pump 535 at the time point N3. Thereby, the lotion, water, and air can be supplied into the foam tank 532 to form a cleaned foam.

The generated cleaning foam is rotated from the discharge port 550u of the dispensing nozzle 550 toward the inner surface of the toilet. As a result, the adhesion of the 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 unit 550a as a stepping motor. Specifically, the foam is dispersed from the discharge port 550u while being shifted from the stop position (20° in FIG. 12) of the time point N3 in FIG. 21 to the limit position (340° in FIG. 12) at the time point N6. Thereafter, the foam is dispersed and returned from the end position of the time point N6 to the stop position of the time point N9.

Further, at the time point N11, the control unit 130 automatically stops the operation of the water pump 516 and the air pump 535 by, for example, timer control. Thereby, the rotation of the rotating foam is automatically ended.

At this time, the control unit 130 continuously operates the water pump 516 and the air pump 535 during the period from the time point N3 to the time point N11 at which the rotary foam is dispersed. 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 time point N9 to the time point N10, the control unit 130 intermittently operates the lottery pump 534 to the forward rotation. stop.

Further, the above-described intermittent operation is based on the results obtained experimentally, and it is possible to efficiently mix the lotion, water, and air in the swirling foam dispersion, and to more stably generate the action of washing the foam. By intermittent operation of the lotion pump 534, it is possible to stably generate a cleaned foam. As a result, the unnecessary use of the lotion can be prevented, and the labor of the lotion replenishment can be reduced.

Further, in the sanitary washing apparatus of the present embodiment, the intermittent operation of the lottery pump 534 is set to operate for, for example, a period of 6 seconds for 2 seconds.

Further, in the timing chart shown in FIG. 21, in order to display the case where it is executed in response to the necessity, the operation of the heat exchanger 700 is depicted by a broken line. The reason for this is that when the temperature of the water supplied from the water pump 516 to the foam tank 532 is lower than 20 ° C at the time of the spin foam dispersion, there is a fear that the washing foam cannot be stably formed. Here, when the water temperature is low, the heat exchanger 700 performs heating control to heat the washing water to, for example, about 20 °C. Moreover, what is shown is the case where the heated washing water is supplied to the foam tank 532. Thereby, the decrease in the foaming property can be prevented to generate a preferable washing foam and supplied to the foam tank 532.

Further, in the timing chart shown in Fig. 21, the detergent pump 534 is reversed at the time point N2 to the time point N3 before the time point N3 at which the foam dispersion is started. The reason for this is that in the present embodiment, a tube pump is used in the lotion pump 534. The tube pump sends the lotion liquid or the like in the tube by the flattening action of the roller. Then, by the reverse operation in the previous stage, the lotion liquid is allowed to flow back from the outlet side of the tube at the portion of the flattened tube, and the portion which has been crushed is returned to the cylindrical shape. Further, the lotion pump 534 is rotated forward in a state where it has returned to the shape of the tube. Thereby, a stable amount of the lotion liquid can be sent to the dispensing nozzle 550.

Moreover, as shown in the timing chart of FIG. 21, the control unit 130 performs an operation of returning the scattering nozzle driving unit 550a from the stop position to the origin position from the time point N11 to the time point N14. Specifically, the scattering nozzle driving unit 550a is driven until it abuts against the origin position. At this time, the scattering nozzle driving unit 550a presses the rotation detecting micro switch arranged at the origin position. Thereby, the control unit 130 recognizes the origin position of the scattering nozzle driving unit 550a constituted by the stepping motor. Thereafter, the control unit 130 drives the scattering nozzle driving unit 550a to return to the stop position. The reason is that there is a case where the stepping motor may slip due to, for example, an increase in some rotational load. Therefore, it is impossible to complete the rotation drive in accordance with the number of driving steps, and there is a deviation in the number of driving steps and the amount of rotation. Then, as described above, the reset operation of the dispensing nozzle driving unit 550a to the origin position is performed. Thereby, the stop position of the start position of the rotary foam dispersion which is the scattering nozzle drive portion 550a can be reset to the correct position, and the driving can be started. As a result, the rotation angle of the dispensing nozzle 550 can be accurately defined with reference to the origin position of the scattering nozzle driving unit 550a, and the rotating foam dispersion can be often performed at a stable position.

Further, for some reasons, for example, there is a case where the washing agent is fixed around the discharge port 550u of the dispensing nozzle 550, and the nozzle driving unit 550a is not rotatably driven. In this case, the presence or absence of the opening/closing of the rotation detecting microswitch that is pressed by the dispensing operation of the home position by the dispensing nozzle driving unit 550a can easily detect the problem of the dispensing nozzle driving unit 550a.

Further, when the opening signal is not input from the rotation detecting micro switch when the rotating foam is dispersed, the washing lamp 223a (refer to FIG. 4) disposed in the operation unit 210 is executed in the lighting display mode to be described below. To notify the user of the bad condition. Thereby, the user can be urged to perform the above operation of the washing switch 223 to perform the washing operation.

Further, in the sanitary washing device of the present embodiment, the time from the start time point N3 to the end time point N12 in the rotational foam dispersion shown in the timing chart of Fig. 21 is set to, for example, about 15 seconds. . Further, about 15 seconds is only an example, and of course, it may be changed to, for example, about 10 seconds or about 25 seconds in accordance with the size of the toilet or the like.

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

With respect to the rotational foam dispersing time set as described above, when, for example, the time delay until the rotation detecting micro switch is pressed is, for example, about 10% or more late, the washing lamp 223a is repeatedly "flashed" or "flashed". The flashing action is performed in the manner of the second blinking action. Thereby, the user can be urged to press the washing switch 223 and perform the washing operation.

In the washing operation, the foam generating portion 560 and the dispensing nozzle 550 are caused to flow out the washing water heated to about 40 ° C by the heat exchanger 700, and washed for about 3 minutes, for example. The washing operation is performed so that the foam generating portion 560, the dispensing nozzle 550, and the like can be washed by the heated washing water. As a result, it is possible to prevent fixation or clogging of the lotion to the bubble generating portion 560, the dispensing nozzle 550, and the like, and to perform stable rotation of the rotating foam.

In the above state, when the washing operation is not performed, the lotion or the like is hardened on the dispensing nozzle 550, and the operation is further deteriorated. In this case, when the time until the rotation detecting micro switch is pressed is delayed by, for example, about 20% or more with respect to the set rotational foam dispersing time, the washing lamp 223a is repeatedly "flashed, flashed", " The flashing and flashing modes are displayed in a blinking manner twice. Thereby, the user can be urged to press the washing switch 223 and perform the washing operation, and the vicinity of the discharge port 550u of the dispensing nozzle 550 can be washed by, for example, a toothbrush or the like.

As described above, by turning on the washing lamp 223a, the user can be urged to cope with the processing based on the detection of the malfunction of the dispensing nozzle driving unit 550a.

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

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

In the above description, the on-off valve 530a has been described as an example, but the invention is not limited thereto. For example, a flow path switching valve such as a three-way valve that is disposed at a branching portion of the branch flow path 530 from the washing water supply flow path 690 may be configured to switch the flow path.

As described above, the operation and control of each portion when the rotary foam is dispersed in the sanitary washing device 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 at the time of 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 portion 560 side at the time points N2 to N3. Further, during about 2 minutes from the time point N3 to N8, in the state where the detergent pump 534 has been stopped, the water pump 516 is used to heat the heat exchanger 700 to a washing water of about 40 ° C. It is delivered to the foam box 532. The supplied washing water is discharged from the dispensing nozzle 550 into the toilet.

Next, during about one minute of the time points N8 to N11, the control unit 130 activates the air pump 535. Thereby, the air pump 535 can be used to send the air to the foam tank 532 together with the washing water which has been warmed to about 40 ° C, and wash washing is performed.

That is, in the washing operation of the washing and washing, only the washing water is first sent to the foam tank 532. Moreover, the air pump 535 is actuated from the middle of the water supply to add air to the foam tank 532 and perform washing. As a result, first, a large amount of the lotion component remaining in the foam tank 532 and the flow path is quickly and efficiently discharged from the dispensing nozzle 550 into the toilet by the washing water. Thereafter, the force of the air bubbles (air) formed by the air pump 535 is added to the foam tank 532. At this time, the bubbles act as a small amount of residual amount of the lotion component and are also washed. As a result, an effective washing and washing can be performed in a short time.

Next, when the washing and washing for about 3 minutes is completed, the control unit 130 reverses the lottery pump 534 in the forward direction at the time points N11 to N14. Thereby, the lottery pump 534 is set to the standby action state so that the next rotating foam spread or the fixed foam spread can be started normally. Further, the control unit 130 automatically ends the washing operation by, for example, a 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 portion when the fixed foam is dispersed in the sanitary washing device will be described with reference to FIG.

Figure 23 is a timing chart showing the dispersion of the fixed foam 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 main body 401, the control unit 130 sets the fixed foam dispensing command issuing mode (foam coating mode). Thereby, at the time point N2 of FIG. 23, the control unit 130 reverses the lottery pump 534 for 2 seconds and then rotates it forward at the time point N3. Further, at time point N3, the control unit 130 starts the operation of the water pump 516 and the air pump 535. Thereby, the lotion, water, and air can be supplied to the foam tank 532 to form a cleaned foam.

The generated washing foam is scattered from the discharge port 550u of the dispensing nozzle 550 toward the inner surface of the toilet. At this time, by dispersing the fixed foam of the washed foam on the inner surface of the toilet bowl, the foam can be accumulated on the water surface of the toilet to cover the foam height of about 10 mm (see Fig. 25). Moreover, by the cushioning action of the washing foam, for example, the splash of urine when the male urinates is suppressed.

In addition, the timing chart at the time of the fixed foam dispersion of FIG. 23 and the timing chart at the time of the rotation foam dispersion of FIG. 21 differ in the operation of the discharge port 550u of the dispersion nozzle 550.

That is, in the case where the rotary foam dispersion shown in Fig. 21 is performed, the discharge port 550u of the dispersion nozzle 550 can be rotationally driven by dispersing the nozzle drive portion 550a. On the other hand, in the case where the fixed foam dispersion shown in Fig. 23 is performed, the difference is that the scattering nozzle driving portion 550a does not rotationally drive the discharge port 550u of the dispensing nozzle 550, but is in a fixed state. Spread the wash foam.

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

Here, the origin position, the stop position, and the limit position of the scattering nozzle driving unit 550a shown in the timing charts of FIGS. 21 to 23 are described by taking the angular position shown below as an example, but Limited by this.

In other words, the position of the origin is 0° (backward) as shown in FIG. 11 , the stop position is 20° (clockwise) as shown in FIG. 11 , and the limit position is shown. The case of the position of 340 (clockwise) shown in Fig. 11 is taken as an example, but is not limited thereto. For example, the position of the origin is 5° (clockwise from the rear). Further, the stop position is 60° (clockwise from the rear to the clockwise direction). In addition, the position of the limit position is 300° (clockwise).

Hereinafter, the operation at the time of dispersing the fixed foam shown in Fig. 23 when the stop position is set to 60° will be described.

First, when the fixed foam dispensing command is issued, the control unit 130 stops the discharge port 550u in the direction in which the discharge port 550u is stopped at a stop position of about 60° in the clockwise direction from the front to the rear. Perform a fixed foam spread immediately.

At this time, the control unit 130 drives the dispensing nozzle driving unit 550a to stand by the direction of the discharge port 550u at a position of about 60° as the stop position. Further, in the standby state, when the fixed foam is instructed to be scattered, the control unit 130 immediately discharges the washing foam toward the inner surface of the toilet without moving the dispensing nozzle 550. Thereby, a foam film having a foam height required for splash suppression can be quickly formed on the water surface in the toilet before the start of male urination.

In this case, when the direction of the stop position of the discharge port 550u is set to the above-described position of 50° to 70° (about 60°), the following effects can be obtained in particular. That is, when the washing foam is discharged at the above-described stop position, the washing foam is incident on the slope of the inner surface of the toilet. The washing foam that hits the slope flows down toward the water surface near the discharge port 115 in such a manner as to rotate on the slope of the inner surface of the toilet. Thereby, a foam film for washing foam can be formed on the entire surface of the water in a short time.

Further, in the present embodiment, the configuration in which the rotary foam is dispersed as shown in FIG. 21 is performed when the manual foam application switch 433 of the remote controller main body 401 is pressed is described as an example, but is not limited. herein. It is also possible to set the rotational foam dispersion to be automatically performed, for example, after defecation (i.e., after the toilet is used). In addition, it is also possible to set the rotation of the rotating foam automatically every other fixed time. Thereby, the dirt is less likely to adhere to the inner surface of the toilet, and the dirt can be more easily removed.

Further, by rotating the foam dispersion in an automatic manner every fixed period of time, it is possible to effectively suppress the dirt near the waterline in the toilet, especially the formation of the annular stain.

At this time, in the case where the rotary foam spread is performed automatically after the defecation, in the sanitary washing apparatus of the present embodiment, the seating sensor 330 detects that the user is standing from the toilet seat 300. And, after, for example, about 60 seconds, the rotating foam spread is performed in 15 seconds.

On the other hand, it is set such that when the toilet seat opening sensor 331 detects that the toilet seat 300 is closed, for example, after about 60 seconds, for 15 seconds, when the toilet seat 331 is not seated in the toilet seat. The time to perform the rotating foam spread.

Further, in the above description, although the description is made by the sensor and the rotation of the foam is performed after about 60 seconds, it is not limited thereto. The switch of the remote controller main body 401 can be arbitrarily changed to, for example, about 10 seconds later, 25 seconds later, or the like. Thereby, the time until the start of the rotation of the rotating foam can be adjusted to an arbitrary time in accordance with the use mode of the user.

Further, in the above description, the description is made by taking as an example approximately 15 seconds as the time for performing the spin foam dispersion, but the present invention is not limited thereto. The switch of the remote controller main body 401 can be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of the scattered foam can be arbitrarily adjusted in accordance with the size of the toilet or the like.

Further, in the present embodiment, the configuration in which the fixed foam dispersion shown in FIG. 23 is performed when the manual splash suppression switch 434 of the remote controller main body 401 is pressed is described as an example, but the invention is not limited thereto. It can also be set to automatically perform a fixed foam spread, for example, when the toilet seat has been opened. Thereby, when the toilet 300 is opened when the male urinates, the fixed foam spread can be automatically performed. As a result, it is possible to effectively suppress the splash of urine when the male urinates.

Further, in the case where the fixed foam dispersion is performed in the automatic operation mode when the toilet seat is opened, when the toilet seat 300 is opened, the fixed foam dispersion is performed, for example, for about 15 seconds.

In the above description, the description has been made by taking as an example a case where the fixed foam dispersion is performed for about 15 seconds, but the present invention is not limited thereto. The switch of the remote controller main body 401 can be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of the scattered foam can be arbitrarily adjusted in accordance with the size of the toilet or the like.

As described above, the operation and control of the respective portions when the fixed foam is dispersed in the sanitary washing device can be performed.

Hereinafter, a configuration in which the automatic operation of the fixed foam dispersion and the rotary foam dispersion is set in the sanitary washing device will be described with reference to FIG.

Fig. 24 is a view for explaining selection of automatic operation when the fixed foam is dispersed in the sanitary washing device and when the rotary foam is dispersed.

Further, when the fixed foam is dispersed and the automatic operation of the rotating foam is dispersed, the automatic setting switch 236 of the operation unit 210 can be pressed every time to select the preferred setting.

Specifically, as shown in the left diagram of FIG. 24, the operation switch 210 is arranged with the operation switch 220, and the automatic selection setting switch 236 is disposed. The automatic selection setting switch 236 is disposed adjacent to the automatic rotation scatter lamp 236a after use, automatically rotates the scatter lamp 236b every fixed period of time, and automatically fixes the foam dispersion indicator 236c when the toilet seat is opened. Further, the setting switch 236 is automatically selected for each pressing, and the lamps are illuminated in the order indicated by the arrows on the right in FIG. Thereby, three kinds of automatic operations can be set in an arbitrary combination in accordance with the preference of the user.

Specifically, H0 indicates that the scatter lamp 236a is automatically rotated after use, the scatter lamp 236b is automatically rotated every fixed period of time, and the self-fixing foam scatter display lamp 236c is turned off when the toilet seat is opened. That is, H0 indicates that all three types of automatic operations are "off".

When the automatic selection setting switch 236 is pressed once by this state of H0, it will become the H1 state in which the automatic rotation scatter lamp 236a is turned on only after use. That is, each time the automatic setting switch 236 is pressed once, the setting is switched to the state of H2, H3, ... H6. When the automatic selection setting switch 236 is pressed once from the state of H6, the state of H7 in which all three automatic operations are "on" is obtained. Further, in the lamp display of Fig. 24, the ○ mark indicates the "OFF" state corresponding to the light-off, and the ● mark indicates the "ON" state corresponding to the light-on.

For example, in the case where the states of H2, H4, H6, and H7 set by the rotary foam dispersion are automatically operated at regular intervals as shown in FIG. 24, the rotary foam described by the timing chart of Fig. 21 can be dispersed. It is executed every 10 hours, for example, in an automatic manner. Thereby, it is possible to suppress the formation of dirt near the water line in the toilet bowl, particularly the annular stain.

Furthermore, the above-described settings executed every three hours can be changed to, for example, every six hours, every about 12 hours, every 24 hours, etc. by the switch of the remote controller main body 401. Arbitrary settings. Thereby, the number of automatic operations and the like can be reduced when the long period of time is not present, and can be arbitrarily adjusted in accordance with the situation of the user.

As described above, the automatic operation setting of the fixed foam dispersion and the rotating foam dispersion can be selected and executed. (Embodiment 2)

Hereinafter, the sanitary washing device according to the second embodiment will be described with reference to Fig. 27 .

Fig. 27 is a perspective view of the sanitary washing device in the second embodiment.

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

That is, the sanitary washing apparatus 1000 of the present embodiment is different from the additional sanitary washing apparatus 100 described in the first embodiment in which the main body 200 is placed on the toilet 110. In addition, since the basic structure and function are the same as that of the sanitary washing apparatus 100 of Embodiment 1, detailed description is abbreviate|omitted. For example, the sanitary washing device 1000 and the sanitary washing device 100 according to the first embodiment have a configuration in which a foam dispensing operation is performed.

Specifically, the sanitary washing device 1000 differs from the sanitary washing device 100 of the first embodiment in that the sanitary washing device 1000 further includes a post-pending flush switch 910, a post-transpiration flush switch 920, and a flush valve (not Graphic). The urinal flush switch 910 and the post-feather flush switch 920 are disposed on the remote controller 400 constituting the operating device. The urinal flush switch 910 is operated by urination to open the flush valve and flush the toilet.

The control portion may also be controlled to perform a rotating foam dispersion on the inner surface of the toilet body by at least one back and forth rotation action when the human body detecting sensor detects that the user enters the toilet.

According to this configuration, when the human body detecting sensor detects the entry of the user into the toilet, it is possible to perform the rotational driving of the discharge port of the dispensing nozzle at least once and back to disperse the inner surface of the toilet. The rotating foam of the net foam is scattered. Thereby, a foam film can be surely formed on the inner surface of the toilet before use to suppress the adhesion of the dirt when it does not occur.

Moreover, the foam generating unit of the sanitary washing device of the present invention includes a foam tank that can supply the washing water by the water discharge amount variable unit and the washing agent of the washing tank to the foam tank by opening the opening and closing valve by the control unit. A lotion pump, and an air pump that supplies air to the foam box. Further, the control unit may be controlled to discharge the washing water or the washing foam of the foam box from the dispensing nozzle.

According to this configuration, not only water or warm water can be discharged to the surface of the washing nozzle or the inner surface of the toilet, but also the washing foam containing the lotion can be discharged. Thereby, the effect of washing and the effect of suppressing adhesion of dirt can be improved. Further, the diffusion of the odor can be suppressed by the washing foam containing the lotion. As a result, it is possible to provide the user with a visually clean feeling and a good feeling of comfort during use.

Moreover, the control unit of the sanitary washing apparatus of the present invention has a washing instruction issuing mode. Further, the control unit may be controlled to open the on-off valve in a state where the detergent agent that can supply the lotion tank of the foam generating portion to the detergent pump of the foam tank has been stopped in the washing command issuing mode The washing water is sent to the foam tank by the spouting amount variable portion and is discharged from the dispensing nozzle.

According to this configuration, the path from the foam tank to the dispensing nozzle can be washed with washing water. Thereby, it is possible to prevent clogging of the path or the dispensing nozzle due to the fixing of the lotion, and the rotation failure of the dispensing nozzle due to the fixing of the lotion. Further, the inner surface of the toilet can be washed in advance to prevent the fixing of the lotion or the like.
