<5> Discharge control and action operation of the spray nozzle on the inner surface of the toilet bowl The discharge control, action and operation of the spray nozzle 550 of the sanitary cleaning device 100 on the inner surface of the toilet bowl 110 will be described below with reference to FIGS. 23 to 28. ..

FIG. 23 is a perspective view showing the appearance of the spray nozzle 550 of the sanitary cleaning device 100. FIG. 24 is a vertical cross-sectional view of the spray nozzle 550. FIG. 25 is a vertical cross-sectional view for explaining the installation state of the spray nozzle 550 in the sanitary cleaning device 100. FIG. 26 is a front view of the installation state of the spray nozzle 550 in the sanitary cleaning device 100. FIG. 27 is a diagram for explaining the discharge operation of the spray nozzle 550 to the inner surface of the toilet bowl 110. FIG. 28 is a chart showing the output of the water discharge amount variable portion at the rotation angle of the discharge port 550u of the spray nozzle 550.

As shown in FIGS. 23 and 24, the spray nozzle 550 includes a spray nozzle drive unit 550a, a body 550c, a rotary nozzle 550d, and the like. The spray nozzle drive unit 550a is composed of, for example, a motor or the like, and rotates the rotary nozzle 550d. The body 550c includes an entrance flow path 550b and an entrance hole 550h. The body 550c supplies the cleaning foam, cleaning water, and the like generated by the foam generating unit 560 (see FIG. 6) to the rotary nozzle 550d. Further, the body 550c is configured to rotatably hold the O-ring 550e rotatably by the spray nozzle drive unit 550a which is a motor and the rotary nozzle 550d shaft-sealed by the O-ring 550f inside. An X ring may be used instead of the O ring 550f. With such a configuration, the torque required to rotate the rotary nozzle 550d can be reduced. Further, the sticking of the rotary nozzle 550d can be prevented more reliably. Therefore, with such a configuration, it is possible to use a small and low torque motor for the spray nozzle drive unit 550a composed of a motor or the like.

Further, the rotary nozzle 550d is fitted with the spray nozzle drive unit 550a via the shaft 550n and is driven to rotate.

The spray nozzle 550 of the present embodiment is configured as illustrated above and operates as follows.

First, the cleaning water or cleaning foam generated by the foam generating unit 560 (see FIG. 6) is supplied from the inlet flow path 550b of the body 550c of the spray nozzle 550. The supplied cleaning water or cleaning foam is supplied into the rotating nozzle 550d from a plurality of inlet holes 550h opened around the rotating nozzle 550d. After that, 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 bowl 110.

As shown in FIGS. 26 and 27, the spray nozzle 550 is installed on the right side of the center of the main body 200. The reason for this is that the buttock cleaning nozzle 831 or the like, which is a cleaning nozzle for cleaning the local part of the human body, is preferentially arranged in the center. Therefore, the spray nozzle 550 is arranged on either the left or right side of the spray nozzle 550, not in the center. The above arrangement may be reversed.

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

In the following, the discharge control of the spray nozzle 550 in the rotary foam spraying command mode when the user is not seated and the toilet seat is closed will be described.

First, when the user enters the toilet room, the control unit 130 of the sanitary cleaning device 100 detects the entry of a person with the human body detection sensor 450. At this time, the control unit 130 is set to the rotary foam spraying command (foam coat) mode in which the cleaning foam is sprayed into the toilet bowl 110 while rotationally driving the direction of the discharge port 550u of the spray nozzle 550. With such a configuration, the control unit 130 shifts to the operation of spraying the rotary foam in the toilet bowl 110. Then, the control unit 130 starts the operation of the water pump 516 shown in FIG. Further, the control unit 130 opens the on-off valve 530a of the branch flow path 530.

In this case, the flow control valve 517 that switches the flow path to the butt cleaning nozzle 831, the bidet cleaning nozzle 832, the nozzle cleaning unit 833, and the like is in the closed state. Therefore, the washing water from the heat exchanger 700 is supplied to the spray nozzle 550 via the branch flow path 530, the check valve 531 constituting the foam generating portion 560, and the foam tank 532. The supplied washing water is discharged from the discharge port 550u of the spray nozzle 550 toward the inner surface of the toilet bowl 110, the butt washing nozzle 831, or the like.

That is, the control unit 130 drives the spray nozzle drive unit 550a of the spray nozzle 550 to rotate the discharge port 550u of the spray nozzle 550. At this time, the washing water or washing foam discharged from the discharge port 550u is sprayed on the entire circumference of the inner surface of the toilet bowl 110, the butt washing nozzle 831, and the like to form a water film or a foam film. With such a configuration, it is possible to prevent the adhesion of filth and the like to the inner surface of the toilet bowl 110.

As shown in FIG. 27, the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl 110 differs depending on the rotation angle direction of the spray nozzle 550.

That is, when the rotation angle of the spray nozzle 550 arranged at the above-mentioned position is changed and the rotation angle of the discharge port 550u of the spray nozzle 550 is 160 °, the distance from the discharge port 550u to the inner surface of the toilet bowl 110 is the longest ( Far). On the other hand, when the rotation angle of the discharge port 550u is 340 ° (corresponding to the position rotated by 180 ° from the above 160 °), the distance from the discharge port 550u to the inner surface of the toilet bowl 110 is the shortest (closest).

Therefore, as shown in FIG. 28, the control unit 130 controls to change the output of the water pump 516 constituting the water discharge amount variable unit according to the rotation angle (distance) of the discharge port 550u of the spray nozzle 550.

The method of controlling the output of the water pump 516 according to the rotation angle of the spray nozzle 550 will be described below.

First, when the control unit 130 detects the user's entry into the toilet room by the human body detection sensor 450, the control unit 130 starts the above control.

At this time, the control unit 130 cleans the water pump 516 while changing the output of the water pump 516 in the range of "high" to "low" according to the rotation angle of the discharge port 550u of the spray nozzle 550, as shown in FIG. 28. Discharge bubbles and the like.

Specifically, the control unit 130 increases the output of the water pump 516 at a rotation angle of around 160 ° where the distance from the discharge port 550u to the inner surface of the toilet bowl 110 is the longest (far). On the other hand, at a rotation angle of around 340 ° where the distance from the discharge port 550u to the inner surface of the toilet bowl 110 is the shortest (near), the control unit 130 reduces the output of the water pump 516.

More specifically, the control unit 130 gradually or continuously outputs the output of the water pump 516 from "low" to "low" in the range where the rotation angle of the discharge port 550u of the spray nozzle 550 is from 0 ° to 160 °. Change to "medium". Similarly, the control unit 130 gradually or continuously changes the output of the water pump 516 from "medium" to "low" in the range where the rotation angle of the discharge port 550u of the spray nozzle 550 is from 160 ° to 340 °. Change. With such a configuration, cleaning water or cleaning foam is sprayed within a predetermined height range over the entire circumference of the inner surface of the toilet bowl 110 according to the distance from the discharge port 550u to the inner surface of the toilet bowl 110.

In this embodiment, the operation of the spray nozzle 550 provided with the rotation control unit described later is exemplified. Therefore, an example is shown in which the output of the water pump 516 changes within the range of the rotation angle of the discharge port 550u from 0 ° to 340 °. However, in the case of the configuration without the rotation restricting portion, the output of the water pump 516 may be changed over the range of one rotation of the rotation angle from 0 ° to 360 °.

That is, the control unit 130 controls the amount (and speed) of the washing water or washing bubbles ejected from the ejection port 550u according to the rotation angle of the spray nozzle 550, that is, the distance between the ejection port 550u and the inner surface of the toilet bowl 110. ..

More specifically, when the washing foam or the washing water is discharged to the front of the toilet bowl 110 located at the farthest distance from the discharge port 550u of the spray nozzle 550, the control unit 130 sets the output of the water pump 516 to "medium". , Discharge cleaning foam or cleaning water with strong force. With such a configuration, the washing foam or washing water can be sufficiently delivered to the inner surface in front of the toilet bowl 110.

On the other hand, when the washing foam or washing water is discharged to the rear of the toilet bowl 110 located at the closest distance from the discharge port 550u of the spray nozzle 550, the output of the water pump 516 is set to "low" and the washing foam or washing water is the most. Discharge with a weak momentum. With such a configuration, it is possible to prevent the occurrence of problems such as washing foam or splashing of washing water.

Then, before use, wash water or wash foam is discharged over the entire inner surface of the toilet bowl 110 to form a water film or foam film. With such a configuration, the adhesion of dirt to the inner surface of the toilet bowl 110 during use is suppressed.

Further, in the present embodiment, when the human body detection sensor 450 detects the user's entry into the toilet room, or when the user operates the spray switch 417 via the main body operation unit 210 or the remote controller 400. The control unit 130 executes so-called toilet foam spraying, in which cleaning foam is sprayed on the inner surface of the toilet bowl 110 in advance before the user uses the toilet bowl 110.

At this time, when the toilet bowl foam is sprayed, the control unit 130 changes the output of the water pump 516 constituting the water discharge amount variable portion as shown in FIG. 28, while changing the output of the toilet bowl 110. Spray cleaning foam on the inner surface. Specifically, the control unit 130 first rotates the spray nozzle drive unit 550a in the normal direction (for example, clockwise) so that the direction of the discharge port 550u of the rotary nozzle 550d is from the rear of the toilet bowl 110 to the front of the toilet bowl 110. Spray the cleaning foam while moving it backwards. Further, after that, the control unit 130 reverses (for example, counterclockwise) the spray nozzle drive unit 550a, and returns the direction of the discharge port 550u of the rotary nozzle 550d from the rear of the toilet bowl 110 to the rear of the toilet bowl 110. Spray the cleaning foam while moving in the direction. That is, the control unit 130 rotates the discharge port 550u of the rotary nozzle 550d in the forward and reverse directions over the inner peripheral surface of the toilet bowl 110, and executes a step operation of spraying the cleaning foam by at least one reciprocating rotation operation. ..

At this time, the control unit 130 controls the output of the water discharge amount variable unit so that the cleaning foam reaches the vicinity of the rim 110a of the toilet bowl 110. With such a configuration, the cleaning foam is sprayed on almost the entire circumference (including the entire circumference) of the inner surface of the toilet bowl 110 in advance before use. Therefore, with such a configuration, a foam film is formed on the inner surface from the front to the rear of the toilet bowl 110, and the adhesion of dirt to the toilet bowl 110 can be suppressed in advance.

In this case, as shown in FIG. 28, the control unit 130 discharges the cleaning foam at a lower output of the water discharge amount variable unit at the time of normal rotation of the spray nozzle drive unit 550a than at the time of reverse rotation of the spray nozzle drive unit 550a. It is preferable to control such a method.

If the output of the variable water discharge amount is lowered, the momentum for discharging the cleaning foam is weakened, so that the cleaning foam can be sprayed from the spray nozzle 550 to a close location (position). Specifically, as in the spraying movement locus TF shown by the dotted line in FIG. 27, in the normal rotation (clockwise), the direction of the discharge port 550u of the rotary nozzle 550d is set to the draft surface 110b inside the rim 110a of the toilet bowl 110. Cleaning foam is sprayed toward the side closer to.

On the other hand, if the output of the variable water discharge amount is increased, the momentum for discharging the cleaning foam is strengthened, so that the cleaning foam can be sprayed from the spray nozzle 550 to a distant place (position). Specifically, as in the spraying movement locus TR shown by the broken line in FIG. 27, in the reverse rotation (counterclockwise), the direction of the discharge port 550u of the rotary nozzle 550d is directed to the side closer to the rim 110a of the toilet bowl 110. And the cleaning foam is sprayed.

With such a configuration, at the initial stage of spraying start (at the time of normal rotation), the draft surface 110b above the discharge port 115 of the toilet bowl 110 can be covered with cleaning foam. After that, at the time of reversal, the cleaning foam can be sprayed on almost the entire circumference of the inner surface of the toilet bowl 110 near the rim 110a. Therefore, with such a configuration, a foam film is formed from the draft surface 110b from the front to the rear of the toilet bowl 110 and from the draft surface 110b to the inner surface of the rim 110a, and the adhesion of dirt to the toilet bowl 110 can be effectively suppressed.

Further, in the present embodiment, the spray nozzle 550 is arranged at a position in front of the main body 200 which is placed and installed on the toilet bowl 110 as shown in FIGS. 2, 25, 26, 27 and the like. ing. That is, the spray nozzle 550 is installed on the front side of the front tip position in the state where the nozzle device 800 for washing the human body is projected from the storage position of the cleaning

nozzles

831 and 832 to the buttock cleaning or bidet cleaning position. .. With such a configuration, the cleaning foam can be sprayed so that the direction of the discharge port 550u of the rotary nozzle 550d is directed to the rear of the toilet bowl 110 during the rotary drive. Therefore, with such a configuration, a foam film of cleaning foam is formed from the front surface to the inner surface of the toilet bowl 110, and the adhesion of dirt to the toilet bowl 110 can be suppressed.

Further, in the above description, an example of controlling so as to change the output of the water pump 516 constituting the water discharge amount variable portion at the time of spraying the rotary foam for spraying the cleaning foam into the toilet bowl 110 has been described, but the present invention is limited to this. do not have. For example, during rotary foam spraying, the output of the water pump 516 is not changed, and the spray nozzle 550 is configured as described below to form a foam film from the front to the rear inner surface of the toilet bowl 110 to the toilet bowl 110. Adhesion of dirt may be suppressed.

In this case, as shown in FIGS. 25 and 26, the rotation axis Ax of the spray nozzle 550 is tilted in the front-rear direction and the left-right direction, and the spray nozzle 550 is installed in the main body 200. Specifically, the rotation axis Ax of the spray nozzle 550 is arranged so as to be inclined toward the front side of the toilet bowl 110 toward the lower side of the spray nozzle 550 in the front-rear direction. Further, the rotation axis Ax of the spray nozzle 550 is arranged so as to be inclined toward the cleaning

nozzles

831 and 832 arranged in the central portion of the main body 200 with the spray nozzle 550 facing downward in the left-right direction. Due to the arrangement configuration of the rotation axis Ax, when the discharge port 550u of the spray nozzle 550 faces in front of the toilet bowl 110 where the distance to the spray position becomes long, the position of the discharge port 550u becomes higher. Therefore, as shown in FIG. 25, the cleaning foam is discharged so that the discharge port direction AcA is in the horizontal direction. Therefore, with such a configuration, the cleaning foam can be sprayed to the vicinity of the rim 110a in front of the toilet bowl 110.

On the other hand, when the discharge port 550u of the spray nozzle 550 faces the rear of the toilet bowl 110 where the distance to the spray position is short, the position of the discharge port 550u is lowered. Therefore, as shown in FIG. 25, the cleaning foam is discharged so that the discharge port direction AcB is in the diagonally downward direction.

Further, when the discharge port 550u faces from the rear to the front on the right side of the toilet bowl 110 in which the distance to the spraying position gradually increases, the direction of the discharge port 550u gradually increases from the discharge port direction AcB to the discharge port direction AcA. Become. Therefore, with such a configuration, the cleaning foam can be sprayed along the vicinity of the rim 110a on the right side of the toilet bowl 110. Further, when the discharge port 550u faces from the front to the rear on the left side of the toilet bowl 110 where the distance to the spraying position gradually decreases, the direction of the discharge port 550u gradually decreases from the discharge port direction AcA to the discharge port direction AcB. Become.

That is, at the time of spraying the rotary foam, the spray nozzle drive unit 550a has a rotary shaft so that the direction of the discharge port 550u of the rotary nozzle 550d is, for example, from the discharge port direction AcB to the discharge port direction AcB via the discharge port direction AcA. It is rotationally driven around Ax. At this time, as described above, the distance from the discharge port 550u to the inner surface of the toilet bowl 110 changes with the rotation of the spray nozzle 550. However, by arranging the rotation axis Ax of the spray nozzle 550 in an inclined manner, the height position of the discharge port 550u of the spray nozzle 550 is changed as shown by the discharge port direction AcA and the discharge port direction AcB. While it can be sprayed with cleaning foam. Therefore, a foam film can be formed from the front of the toilet bowl 110 to the inner surface near the rear rim 110a along the spraying movement locus TR as shown by the dashed arrow in the counterclockwise direction in FIG. 27. Therefore, with such a configuration, it is possible to suppress the adhesion of dirt over the entire inner surface from the front to the rear of the toilet bowl 110.

According to the above configuration, when the rotary foam is sprayed, the cleaning foam is discharged at a constant output without changing the output of the water pump 516. Therefore, even when the clockwise rotating foam is sprayed, the cleaning foam is sprayed in the opposite direction in the same locus as the spraying movement locus TR as shown by the left-handed dashed arrow in FIG. 27.

In the present embodiment, the rotation axis Ax of the spray nozzle 550 has an inclination angle β in the front-rear direction shown in FIG. 25 of, for example, 20 degrees, and an inclination angle γ in the left-right direction shown in FIG. 26, for example, 10 degrees. Have been placed. The angle can be arbitrarily changed depending on the shape of the toilet bowl 110, the arrangement position of the spray nozzle 550, and the like.

Further, the height position of the discharge port 550u of the spray nozzle 550 is set so as to be lower than the upper end surface 110c of the toilet bowl 110 at any rotation position.

In the above explanation, forward rotation is described as clockwise rotation when viewed from above in FIG. 27, and reverse rotation is described as counterclockwise rotation, but the present invention is not limited to this. For example, forward rotation may be referred to as counterclockwise rotation when viewed from above, and reverse rotation may be referred to as clockwise rotation. That is, in the present embodiment, the direction in which the discharge port 550u of the spray nozzle starts to rotate at the time of spraying is referred to as forward rotation, and the return direction is referred to as reverse rotation, and the rotation direction is not particularly limited.

As described above, the control unit 130 changes the output of the water pump 516 according to the rotation angle of the discharge port 550u of the spray nozzle 550. With such a configuration, the cleaning water from the spray nozzle 550 ensures that the cleaning water or the cleaning foam reaches the front, side, and rear of the inner surface of the toilet bowl 110 at different distances from the discharge port 550u of the spray nozzle 550. Alternatively, cleaning foam can be discharged. Further, with such a configuration, a water film or a foam film can be formed on a wide range of the inner surface of the toilet bowl 110, and adhesion of dirt to the toilet bowl 110 can be suppressed.

In the above embodiment, an example in which "high" and "low" are set based on the average level "medium" of the output of the water pump 516 has been described, but the present invention is not limited to this. For example, the control unit 130 and the water pump 516 may be configured to increase or decrease the average level "medium" itself of the output of the water pump 516 so that the reference level of the output of the water pump 516 can be changed. .. In this case, it is preferable that the main body operation unit 210 or the remote controller 400 is provided with a level changeover switch for adjusting the average level of the output of the water pump 516. With such a configuration, even if the size of the toilet bowl 110 in which the sanitary cleaning device 100 is installed is different, the cleaning water or the cleaning foam can be discharged so as to reach the entire inner surface of the toilet bowl 110. Further, the sanitary cleaning device 100 may be configured so that the height position (relative to the horizontal plane) of the cleaning foam sprayed on the inner surface of the toilet bowl 110 can be arbitrarily changed. With such a configuration, a water film or a foam film can be formed at an arbitrary position on the inner surface of the toilet bowl 110 to suppress the adhesion of dirt to the toilet bowl 110.

Further, in the above embodiment, the control unit 130 has described, as an example, discharge control in which the output of the water pump 516 is changed according to the rotation angle of the discharge port 550u of the spray nozzle 550, but the present invention is not limited to this. For example, in addition to the change in the output of the water pump 516, the control unit 130 may control to change the rotation speed of the spray nozzle drive unit 550a according to the rotation angle of the discharge port 550u.

That is, in the present embodiment, the output of the water pump 516 is changed to change the momentum of discharging the washing water or the washing foam. With such a configuration, the washing water or the washing foam is surely sprayed to the inner surface of the toilet bowl 110 far from the discharge port 550u of the spray nozzle 550, and the rebound on the inner surface of the toilet bowl 110 near the discharge port 550u of the spray nozzle 550 is effective. Can be suppressed.

When the discharge port 550u of the spray nozzle 550 is rotated at a constant rotation speed, the spray density of the cleaning foam or the cleaning water becomes sparse at a place where the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl 110 is long. On the other hand, in a place where the distance to the inner surface of the toilet bowl 110 is short, the spraying density of the washing foam or the washing water becomes dense.

Therefore, in the present embodiment, the rotation speed of the spray nozzle 550 may be further changed by the spray nozzle drive unit 550a according to the rotation angle of the discharge port 550u. With such a configuration, the washing water or the washing foam can be sprayed with a uniform spraying density over the entire circumference of the inner surface of the toilet bowl 110.

Even when the output of the water pump 516 is changed to spray the washing water or the washing foam, the spraying density of the washing water or the washing foam can be made uniform to some extent.

By changing the rotation speed of the spray nozzle drive unit 550a according to the rotation angle of the spray nozzle 550 and spraying the cleaning foam or the cleaning water, the spray density can be made more even. In other words, the wash foam or wash water can be sprayed over the entire circumference of the inner surface of the toilet bowl 110 with a more uniform spray density.

That is, when the rotation speed is constant, as shown in FIG. 27, the washing water or washing foam sprayed in the vicinity of the rotation angle 160 °, which is the farthest distance from the discharge port 550u of the spray nozzle 550, that is, in front of the toilet bowl 110 , Disperse and disperse density becomes sparse. Therefore, when the washing foam or the washing water is discharged to the front of the toilet bowl 110, the rotation speed of the spray nozzle 550 is made the slowest. With such a configuration, it takes a long time for the discharge port 550u of the spray nozzle 550 to pass near the front of the toilet bowl 110. Therefore, with such a configuration, the spraying density of the cleaning foam can be increased.

On the other hand, when the rotation speed of the spray nozzle 550 is constant, the washing bubbles or washing water discharged to the rear of the toilet bowl 110 at a rotation angle of around 340 °, which is the closest distance from the discharge port 550u of the spray nozzle 550, gather. The spraying density becomes dense. Therefore, the rotation speed of the spray nozzle 550 is maximized. With such a configuration, the time for passing the rear vicinity of the toilet bowl 110 of the discharge port 550u of the spray nozzle 550 is shortened. Therefore, with such a configuration, the spraying density of the cleaning foam can be reduced.

That is, the distribution of the cleaning foam or the cleaning water sprayed on the inner surface of the toilet bowl 110 can be made uniform (eliminate the shading) by changing the rotation speed of the spray nozzle 550. Therefore, by forming an even foam film, it is possible to more effectively suppress the adhesion of dirt over the entire circumference of the inner surface of the toilet bowl 110.

As described above, the control unit 130 changes the rotation speed of the spray nozzle drive unit 550a according to the rotation angle of the discharge port 550u of the spray nozzle 550. For example, when the direction of the discharge port 550u of the spray nozzle 550 is a rotation angle toward the front of the toilet 110, which has a long distance to the inner surface of the toilet 110, the rotation speed of the spray nozzle drive unit 550a is gradually reduced (decreased). On the other hand, when the direction of the discharge port 550u is a rotation angle toward the rear of the toilet bowl 110 where the distance to the inner surface of the toilet bowl 110 is short, the speed of the spray nozzle drive unit 550a is gradually increased (high speed). With such a configuration, the cleaning water or the cleaning foam can be evenly discharged to the front, side, and rear of the toilet bowl 110 at different distances without uneven spraying density. Therefore, with such a configuration, the water film or foam film uniformly formed on the inner surface of the toilet bowl 110 can effectively suppress the adhesion of dirt.

Further, in the present embodiment, when the control unit 130 detects the entry of a person by the human body detection sensor 450, the control unit 130 sprays the cleaning water or the cleaning foam on the inner surface of the toilet bowl 110 from the spray nozzle 550 in advance, that is, the so-called toilet bubble spraying is executed. Control to do. Specifically, the control unit 130 controls the spray nozzle drive unit 550a to automatically stop the rotary nozzle 550d by spraying bubbles while rotationally driving the rotary nozzle 550d, for example, at least once. With such a configuration, a water film or a foam film can be formed on the inner surface of the toilet bowl 110 in advance before the user uses the sanitary cleaning device 100. Therefore, with such a configuration, it is possible to effectively suppress the adhesion of dirt to the inner surface of the toilet bowl 110 when the toilet bowl 110 is used.

In the present embodiment, an example in which the spray nozzle 550 is rotated once reciprocating to spray the cleaning foam or the cleaning water before use is described, but the present invention is not limited to this. For example, the number of times the spray nozzle 550 is rotated is arbitrary as long as the number of times the washing foam or washing water to be sprayed spreads sufficiently on the inner surface of the toilet bowl 110. In this case, it is preferable that the sanitary cleaning device 100 is configured so that the user can select and set the number of reciprocations of the spray nozzle 550 when spraying the toilet foam by the main body operation unit 210 or the remote controller 400.

Further, in the present embodiment, the rotation direction of the spray nozzle 550 is not particularly mentioned, and the rotation nozzle 550d is configured to rotate once. The reason for this is that when the rotary nozzle 550d of the spray nozzle 550 is rotated all around in only one of the right direction and the left direction, the spraying direction of the washing water or the washing foam is always the same. Therefore, in the present embodiment, an example is shown in which cleaning foam or cleaning water is sprayed on the inner surface of the toilet bowl 110 from two directions of forward and reverse rotation by one reciprocating rotation. With such a configuration, the occurrence of so-called spray omission portions can be further reduced. Therefore, with such a configuration, it becomes possible to more uniformly disperse the washing foam or the washing water on the inner surface of the toilet bowl 110. Further, with such a configuration, it is possible to suppress the adhesion of dirt to the inner surface of the toilet bowl 110 with a small number of spraying times (time). The reciprocating rotation is not limited to one round trip, and may be set to a plurality of times such as two round trips or three round trips.

Specifically, as shown in FIG. 28, first, the rotating nozzle 550d of the spray nozzle 550 is rotated forward (for example, clockwise) from a rotation angle of 0 ° corresponding to the rear side of the toilet bowl 110 to a rotation angle of 340 °. And stop it once. After that, the rotation nozzle 550d is reversed (for example, counterclockwise) from the rotation angle of 340 ° to the rotation angle of 0 °, and is stopped after one reciprocating rotation.

In this case, in the sanitary cleaning device 100, for example, a rotation regulating unit (not shown) which is a mechanical stopper regulates the rotatable range of the rotating nozzle 550d of the spray nozzle 550 from a rotation angle of 0 ° to a rotation angle of 340 °. It is preferable to be provided.

Specifically, the rotation control unit is composed of, for example, a protrusion formed on a part of the outer circumference of the rotation nozzle 550d and a rotation control wall of the body 550c. With such a configuration, when the protrusion rotates and physically contacts the rotation restricting wall, the operation of the rotating nozzle 550d to rotate is restricted. That is, the motor constituting the spray nozzle drive unit 550a slips and slips due to contact. With such a configuration, the rotary nozzle 550d is restricted from rotating beyond the rotatable range.

As described above, the spray nozzle 550 configured as described above includes a rotation regulating unit that regulates the rotation range, and reciprocates the spray nozzle 550 within a rotatable range that is not regulated by the rotation regulating unit. Then, the washing foam or washing water is sprayed on the inner surface of the toilet bowl 110 from two directions of forward and reverse rotation by reciprocating rotation. With such a configuration, the occurrence of so-called spray omission portions is reduced. Therefore, it is possible to more uniformly spread the cleaning foam or the cleaning water on the inner surface of the toilet bowl 110. Therefore, with such a configuration, it is possible to form a foam film capable of suppressing the adhesion of dirt to the inner surface of the toilet bowl 110 with a small number of spraying times (time).

Further, the control unit 130 can always recognize the position where the protrusion of the rotary nozzle 550d of the spray nozzle 550 configured as described above abuts on the rotation restricting portion as the origin of the rotation position of the spray nozzle drive unit 550a. Therefore, with such a configuration, it is possible to prevent the occurrence of origin deviation due to the reciprocating operation of the rotary nozzle 550d. Further, with such a configuration, the positional accuracy of the rotation angle of the rotation nozzle 550d with respect to the inner surface of the toilet bowl 110 can be improved. That is, it is possible to reduce variations such as positional deviation with respect to a predetermined position on the inner surface of the toilet bowl 110. Therefore, with such a configuration, the cleaning foam or the cleaning water can be sprayed from the discharge port 550u of the spray nozzle 550 at an accurate position on the inner surface of the toilet bowl 110 at an appropriate discharge output and rotation speed.

In the present embodiment, a configuration for physically restricting the rotation range of the spray nozzle 550 has been described as an example, but the present invention is not limited to this. If the misalignment of the origin of the spray nozzle 550 does not matter, the sanitary cleaning device 100 may be configured to simply rotate the spray nozzle 550 in the forward and reverse directions with the spray nozzle drive unit 550a. With such a configuration, the rotation restricting unit becomes unnecessary, and various operations of the rotary nozzle 550d such as forward / reverse rotation or unidirectional rotation become possible. Therefore, with such a configuration, the rotary nozzle 550d can be operated more appropriately depending on the situation such as dirt on the inner surface of the toilet bowl 110. In this case, it is preferable that the control unit 130 sets the origin of the spray nozzle 550 to the vicinity of the rotation angle of 160 ° to be inverted, and controls so that the rotation speed gradually decreases in the vicinity thereof. With such a configuration, it is possible to reduce the load applied at the time of sudden reversal of the spray nozzle drive unit 550a.

Hereinafter, the configuration of the foam generating unit 560 of the sanitary cleaning device 100 of the present embodiment will be described with reference to FIG.

As shown in FIG. 6, the foam generation unit 560 has an on-off valve in the branch flow path 530 branched from the wash water supply flow path 690 between the water pump 516 constituting the water discharge amount variable unit and the flow control valve 517. It is connected via the 530a and the check valve 531. Then, by opening and closing the on-off valve 530a, the washing water is supplied to the foam generating portion 560 via the branch flow path 530.

The foam tank 532 is connected to the spray nozzle 550 downstream. The foam tank 532 is connected to the detergent tank 533 that supplies the detergent via the detergent pump 534.

The foam tank 532 is further connected to the air pump 535. The air pump 535 sends air to the foam tank 532 to generate cleaning foam and the like. Then, the air pump 535 supplies the cleaning water or the generated cleaning foam to the spray nozzle 550.

The bubble generating unit 560 configured as described above operates as follows.

First, the control unit 130 opens the on-off valve 530a. Then, the control unit 130 drives the water pump 516 to send the washing water from the heat exchanger 700 to the foam tank 532 of the foam generation unit 560. In the foam tank 532, the detergent 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. With such a configuration, cleaning foam is generated in the foam tank 532. The generated cleaning foam is supplied to the spray nozzle 550 and is discharged to the inner surface of the toilet bowl 110 from the discharge port 550u of the rotary nozzle 550d.

At this time, the discharge amount and the discharge momentum (discharge speed and discharge pressure) of the washing water or washing bubbles discharged from the spray nozzle 550 are increased or decreased according to the increase or decrease of the outputs of the water pump 516 and the air pump 535. With such a configuration, as described with reference to FIG. 27, the washing foam or washing water can be evenly sprayed on the inner surface of the toilet bowl 110. That is, the air pump 535 of the foam generation unit 560 also functions as a water discharge amount variable unit in the same manner as the water pump 516.

In the above description, the configuration in which the on-off valve 530a is provided in the branch flow path 530 has been described as an example, but the present invention is not limited to this. For example, a flow path switching valve may be provided at the branch portion of the branch flow path 530 and the wash water supply flow path 690.

That is, the foam generation unit 560 of the present embodiment includes a foam tank 532 between the on-off valve 530a and the spray nozzle 550. The foam tank 532 is supplied with detergent from the detergent tank 533 to generate cleaning foam. The sanitary cleaning device 100 of the present embodiment is configured such that the cleaning foam generated in the foam tank 532 is discharged from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl 110.

With such a configuration, a foam film is formed on the inner surface of the toilet bowl 110 by a cleaning foam containing a detergent, not a mere water film by spraying water or hot water. Therefore, with such a configuration, it is possible to more effectively suppress the adhesion of dirt to the inner surface of the toilet bowl 110.

In addition, the cleaning foam containing detergent can effectively suppress the odor generated from filth and the like. In addition, the cleaning foam gives the user a visually clean image. Therefore, with such a configuration, the comfort feeling of the user can be further improved.

In the above embodiment, the configuration in which the cleaning water or the cleaning foam is sprayed on the inner surface of the toilet bowl 110 when the human body detection sensor 450 detects the entry of a person has been described as an example, but the present invention is not limited to this. .. For example, the spraying switch 417 provided on the main body operation unit 210 or the remote controller 400 may be operated by a person to spray the washing water or the washing foam. With such a configuration, even when the toilet in which the sanitary cleaning device 100 is installed is not used, if the inner surface of the toilet bowl 110 is concerned about dirt, the inner surface of the toilet bowl 110 is sprayed with cleaning foam containing detergent to remove the dirt. Can be dropped. Further, it is possible to prevent stubborn stains from being formed on the draft surface 110b and the like due to drying. That is, the user can operate the spray switch 417 to form a foam film made of cleaning foam containing detergent on the inner surface of the toilet bowl 110 at any time. Therefore, with such a configuration, the inner surface of the toilet bowl 110 can be kept clean.

Further, in the above embodiment, the sanitary cleaning device 100 determines in advance whether to spray the cleaning water or the cleaning foam on the inner surface of the toilet bowl 110 by the user using the spraying selection switch of the main body operation unit 210 or the remote controller 400 (FIG. (Not shown) may be configured to be arbitrarily selected. With such a configuration, it is possible to arbitrarily select whether or not cleaning water or cleaning foam should be sprayed depending on the degree of dirt on the inner surface of the toilet bowl 110 or the generation of odor. Therefore, with such a configuration, wasteful use of the detergent can be suppressed, and cost performance can be improved.

Further, in the above embodiment, the control unit 130 may be configured to have a sugi issuing mode that can be selected and instructed by the switch button of the main body operation unit 210 or the remote controller 400.

In this case, in the Sugi issuance mode, the control unit 130 first opens the on-off valve 530a in a state where the detergent pump 534 that supplies the detergent of the detergent tank 533 of the foam generation unit 560 to the foam tank 532 is stopped. With such a configuration, the water pump 516 sends the washing water to the foam tank 532. The sent washing water is supplied from the foam tank 532 to the spray nozzle 550 and discharged into the toilet bowl 110.

At this time, the route from the foam tank 532 to the spray nozzle 550 is first rinsed with washing water. With such a configuration, if the detergent remains in the path from the foam tank 532 to the spray nozzle 550 and in the spray nozzle 550, it is washed away with washing water in advance. Therefore, with such a configuration, it is possible to prevent the path from the foam tank 532 to the spray nozzle 550, the clogging of the spray nozzle 550, and the rotation failure of the spray nozzle 550 due to the sticking of the detergent. Further, with such a configuration, the inner surface of the toilet bowl 110 can be rinsed with washing water in advance.

That is, the detergent pump 534 is in the stopped state during the rinsing operation in the Sugi announcement mode. Therefore, the detergent is not supplied to the foam tank 532, and only the washing water is sent. With such a configuration, the path from the foam tank 532 to the spray nozzle 550 is rinsed with the supplied wash water. At the same time, the washing water rinsed along the path from the foam tank 532 to the spray nozzle 550 is sprayed from the spray nozzle 550 to the inner surface of the toilet bowl 110. Therefore, with such a configuration, the inner surface of the toilet bowl is also washed with washing water at the same time as the washing of the route.

In the rinsing operation in the Sugi announcement mode, rinsing is usually performed with washing water whose temperature is not controlled. However, the sanitary cleaning device 100 is configured to heat the temperature of the cleaning water to, for example, about 40 ° C. in the heat exchanger 700, supply the heated cleaning water, and perform the rinsing operation. May be. With such a configuration, the solubility of the residual detergent or the like in the washing water can be increased, and a more excellent rinsing effect can be obtained.

Further, the above-mentioned susugi issuing mode is set so that the route from the foam tank 532 to the spray nozzle 550 or the inner surface of the toilet bowl 110 is arbitrarily rinsed by operating the susugi switch 223 of the main body operation unit 210 of the user. You may.

Specifically, as shown in FIG. 4, a sugi lamp 223a such as an LED is provided in the vicinity of the sugi switch 223 of the main body operation unit 210 in which the sugi issuance mode is set. Then, when a predetermined time such as 20 days has elapsed since the previous rinsing was executed, the control unit 130 automatically blinks the sugi lamp 223a. With such a configuration, it is possible to prevent forgetting to rinse and prevent clogging of the path from the foam tank 532 to the spray nozzle 550.

Further, in the sanitary cleaning device 100 of the present embodiment, when the cleaning foam is sprayed on the inner surface of the toilet bowl 110, the output operation of the water pump 516 as shown in FIG. 28 is performed according to the rotation angle of the discharge port 550u of the spray nozzle 550. Similarly, the control unit 130 may be configured to change the output of the air pump 535 to disperse the cleaning foam from the discharge port 550u. With such a configuration, the cleaning foam can be discharged to the front, side, and rear of the toilet bowl 110 at different distances from the discharge port 550u of the spray nozzle 550 so that the cleaning foam can be effectively delivered. Therefore, with such a configuration, it is possible to form a foam film on the entire inner surface of the toilet bowl 110 and suppress the adhesion of dirt to the toilet bowl 110.

Specifically, as described with reference to FIG. 27, the control unit 130 is an air pump at a rotation angle of around 160 ° at which the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl 110 is the longest (far). Increase the output (air pressure) of 535 to large (high). With such a configuration, it is possible to increase the air pressure by the air pump 535 and strengthen the momentum to blow the cleaning foam from the discharge port 550u to a long distance.

On the other hand, the output (air pressure) of the air pump 535 is made small (low) near the rotation angle of 340 ° where the distance from the discharge port 550u to the inner surface of the toilet bowl 110 is the shortest (near). With such a configuration, the air pressure by the air pump 535 can be lowered to weaken the momentum of blowing the cleaning foam.

That is, the control unit 130 adjusts the air pressure discharged from the air pump 535 according to the distance from the discharge port 550u of the spray nozzle 550 to the inner surface of the toilet bowl 110. Therefore, with such a configuration, the cleaning foam can be uniformly and evenly discharged to the inner surface of the toilet bowl 110.

Further, in the above embodiment, the sanitary cleaning device 100 may further include a stain detection unit (not shown) that detects stains on the toilet bowl 110 with an image element such as a CCD (Charge Coupled Device). In this case, the control unit 130 drives the spray nozzle 550 to reciprocate the portion where the stain remains based on the detection result of the stain detection unit, and intensively sprays the cleaning foam. With such a configuration, dirt adhering to the inner surface of the toilet bowl 110 can be effectively removed. In addition to the method of reciprocating only the dirty portion, the control unit 130 may be configured to rotationally drive the rotation speed of the discharge port 550u of the spray nozzle 550 passing through the dirty portion at a lower speed. Further, the control unit 130 may be configured to further increase the output of the water pump 516 or the air pump 535 as the spray nozzle 550 passes through the dirty portion. With such a configuration, dirt adhering to the inner surface of the toilet bowl 110 can be effectively removed.

Hereinafter, the operation and control of each part at the time of spraying the rotary foam in the sanitary cleaning device 100 of the present embodiment will be described with reference to FIG. 29.

FIG. 29 is a time chart at the time of spraying rotary foam in the sanitary cleaning device 100 according to the embodiment of the present disclosure.

As shown in FIG. 29, at the time point N1, the user presses the manual foam coat switch 433 of the remote controller main body 401. As a result, the control unit 130 reverses the detergent pump 534 at the time point N2, for example, for 2 seconds, and then rotates the detergent pump 534 forward at the time point N3. The control unit 130 starts the operation of the water pump 516 and the air pump 535 at the time point N3. As a result, detergent, water, and air are supplied into the foam tank 532 to generate cleaning foam.

The generated cleaning foam is sprayed on the inner surface of the toilet bowl 110 from the discharge port 550u of the spray nozzle 550. As a result, it is possible to suppress the adhesion of dirt to the inner surface of the toilet bowl 110 and to easily remove the dirt.

In this case, the discharge port 550u of the spray nozzle 550 is rotationally driven by, for example, the spray nozzle drive unit 550a which is a stepping motor. Specifically, the control unit 130 sprays bubbles from the discharge port 550u while rotating forward from the stop position at the time point N3 (20 ° in FIG. 27) to the end position of the time point N6 (340 ° in FIG. 27). .. After that, bubbles are sprayed while reversing from the end position of the time point N6 to the stop position of the time point N9, and the process returns.

Then, 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. As a result, the rotary foam spraying is automatically terminated.

In this case, the control unit 130 continuously operates the water pump 516 and the air pump 535 from the time point N3 to the time point N11 when the rotary foam is sprayed. On the other hand, the control unit 130 intermittently operates the detergent pump 534 so as to rotate forward and stop during the period from the time point N3 to the time point N4, the period from the time point N6 to the time point N7, and the period from the time point N9 to the time point N10. do.

The above intermittent operation operation is based on the experimentally obtained result that the detergent, water, and air are efficiently mixed during the rotary foam spraying, and the cleaning foam can be generated more stably. The intermittent operation of the detergent pump 534 can stably generate cleaning foam. As a result, it is possible to prevent wasteful use of the detergent and reduce the trouble of replenishing the detergent.

In the sanitary cleaning device 100 of the present embodiment, the intermittent operation of the detergent pump 534 is set to operate for 2 seconds in a cycle of 6 seconds, for example.

Further, in the time chart shown in FIG. 29, the operation of the heat exchanger 700 is drawn by a broken line in order to show an example of the case where the heat exchanger 700 is executed as needed. The reason for this is that if the temperature of the water supplied from the water pump 516 to the foam tank 532 during rotary foam spraying is lower than 20 ° C., cleaning foam may not be stably generated. Therefore, when the water temperature is low, the washing water is heated by controlling the heating with the heat exchanger 700 so that the temperature becomes, for example, about 20 ° C. Then, it is shown to operate when the heated washing water is supplied to the foam tank 532. As a result, it is possible to prevent a decrease in foaming property and generate and supply preferable cleaning foam to the foam tank 532.

Further, in the time chart shown in FIG. 29, the detergent pump 534 is reversed from the time point N2 immediately before the time point N3 when the rotary foam spraying is started to the time point N3. The reason for this is that in the present embodiment, a tube pump is used for the detergent pump 534. The tube pump sends out the detergent solution in the tube by the crushing operation of the roller. Therefore, by the reversing operation immediately before, the detergent solution is made to flow back from the outlet side of the tube to the portion of the crushed tube, and the crushed portion is restored to a cylindrical shape. The control unit 130 rotates the detergent pump 534 in the normal direction while the shape of the tube is restored. With such a configuration, a stable amount of detergent liquid can be delivered to the spray nozzle 550.

Further, as shown in the time chart of FIG. 29, from the time point N11 to the time point N14, the control unit 130 executes an operation of returning the spray nozzle drive unit 550a from the stop position to the origin position. Specifically, the spray nozzle drive unit 550a is driven until it comes into contact with the origin position. The spray nozzle drive unit 550a presses the rotation detection micro switch arranged at the origin position. With such a configuration, the control unit 130 recognizes the origin position of the spray nozzle drive unit 550a configured by the stepping motor. After that, the control unit 130 drives the spray nozzle drive unit 550a so as to return to the stop position. The reason for this is that the stepping motor may cause a slip phenomenon due to, for example, an increase in some rotational load. Therefore, the rotation drive that matches the number of drive steps cannot be performed, and a difference occurs between the number of drive steps and the amount of rotation. Therefore, as described above, the reset operation of the spray nozzle drive unit 550a to the origin position is executed. With such a configuration, the stop position, which is the start position of the rotary bubble spraying of the spray nozzle drive unit 550a, can be reset to the correct position and the drive can be started. Therefore, with such a configuration, the rotation angle of the spray nozzle 550 can be accurately defined with reference to the origin position of the spray nozzle drive unit 550a, and the rotary foam can always be sprayed at a stable position.

Further, for some reason, for example, the detergent may be stuck around the discharge port 550u of the spray nozzle 550, and the spray nozzle drive unit 550a may not be rotationally driven. In this case, a defect in the spray nozzle drive unit 550a can be easily detected depending on whether or not the rotation detection micro switch pressed by the reset operation of the spray nozzle drive unit 550a to the origin position is on or off.

Then, when the on signal is not input from the rotation detection micro switch at the time of spraying the rotation bubbles, the control unit 130 executes the sugi lamp 223a (see FIG. 4) arranged in the main body operation unit 210 with the lighting display described below. Let the user know the problem. With such a configuration, it is possible to encourage the user to operate the above-mentioned sugi switch 223 and execute the sugi operation.

In the sanitary cleaning device 100 of the present embodiment, the time from the time point N3 at which the rotary foam spraying shown in the time chart of FIG. 29 is started to the time point N12 at the end time is set to, for example, about 15 seconds. Note that about 15 seconds is an example, and may be changed to, for example, about 10 seconds or about 25 seconds according to the size of the toilet bowl 110 or the like.

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

When, for example, the time until the rotation detection micro switch is pressed is delayed by, for example, about 10% or more with respect to the rotation bubble spraying time set as described above, the control unit 130 sets the Sugi lamp 223a to "Chika" or "Chika". It is lit and displayed so that it repeats one blinking operation. As a result, the user is urged to press the sugi switch 223 to perform the sugi operation.

In the sugi operation, washing is performed for, for example, about 3 minutes while flowing washing water heated to about 40 ° C. by the heat exchanger 700 through the foam generating unit 560 and the spray nozzle 550. By the sugi operation, the foam generating portion 560, the spray nozzle 550, and the like are rinsed with heated washing water. This prevents the detergent from sticking or clogging the foam generating portion 560, the spray nozzle 550, or the like, and enables stable rotary foam spraying.

In the above state, if the sugi operation is not executed, the detergent or the like solidifies on the spray nozzle 550, and the movement becomes worse. In this case, if the time until the rotation detection micro switch is pressed is delayed by, for example, about 20% or more with respect to the set rotation bubble spraying time, the Sugi lamp 223a is changed to "Chika, Chika", "Chika, Chika" 2 Turns on and displays so that the blinking operation is repeated once. With such a configuration, the user is urged to clean the vicinity of the discharge port 550u of the spray nozzle 550 while pressing the sugi switch 223 to perform the sugi operation while rubbing the vicinity of the discharge port 550u of the spray nozzle 550, for example, with a toothbrush.

As described above, the sanitary cleaning device 100 is configured to light and display the sugi lamp 223a, thereby urging the user to take action based on the detection of the malfunction of the spray nozzle drive unit 550a.

Further, in the flow path switching time chart shown in FIG. 29, at time points N2 to N3, the supply destination of the washing water from the water pump 516 (see FIG. 6) of the water circuit is set from the nozzle device 800 side to the bubble generation unit 560 side. Shows the operation of switching to. Further, at time points N11 to N13, the operation of switching the supply destination of the washing water from the foam generating portion 560 side to the nozzle device 800 side is shown.

Specifically, at time points N2 to N3, the control unit 130 closes the flow control valve 517, opens the on-off valve 530a, and switches the supply destination of the washing water to the foam generation unit 560. On the other hand, at the time points N11 to N13, the control unit 130 closes the on-off valve 530a, opens the flow control valve 517, and switches the supply destination of the washing water to the nozzle device 800.

In the above, the on-off valve 530a is described as an example, but the description is not limited to this. The sanitary cleaning device 100 of the present embodiment is, for example, a flow path switching valve such as a three-way valve arranged at a branching point where the branch flow path 530 is branched from the washing water supply flow path 690. May be configured to do.

Further, the time chart of FIG. 29 describes the operation when the user presses the manual foam coat switch 433 of the remote controller main body 401. Separately from this, in the sanitary cleaning device 100 of the present embodiment, the seating sensor 330 detects that the user has left the toilet seat 300, and one minute after the user has left the toilet seat 300, the operation described in the time chart of FIG. 29 A similar operation may be performed to disperse cleaning foam on the inner surface of the used toilet bowl 110 and the foam film may be configured to keep the toilet bowl 110 hygienic.

As described above, the operation and control of each part at the time of spraying the rotary foam in the sanitary cleaning device 100 is executed.
