The dotted line shown in FIG. 6 shows a state where the control unit 130 is electrically connected to each component, and is controlled by the control unit 130. <3> Discharge control of the inner surface of the toilet with a spray nozzle and its functions and actions

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

FIG. 7 is a perspective view showing an external appearance of a spray nozzle of the sanitary washing device. FIG. 8 is a longitudinal sectional view of the spray nozzle. FIG. 9 is a longitudinal sectional view showing the installation state of the spray nozzles in the sanitary washing device. FIG. 10 is a front view showing the installation state of the spray nozzles in the sanitary washing device. FIG. 11 is a plan view showing the installation positions of the spray nozzles and the rotation angle of the spray nozzles in the sanitary washing device. FIG. 12 is a graph showing an output of a variable amount of water discharge at a rotation angle of a discharge outlet of the spray nozzle.

As shown in FIGS. 7 and 8, the spray nozzle 550 is configured by a spray nozzle driving section 550 a, a main body 550 c, a rotating nozzle 550 d, and the like. The scattering nozzle driving unit 550a is configured by, for example, a motor or the like, and rotationally drives the rotary nozzle 550d. The main body 550c includes an inlet flow path 550b and an inlet hole 550h, and supplies washing foam, washing water, and the like generated by the foam generating unit 560 shown in FIG. 6 to the rotary nozzle 550d. In addition, the main body 550c holds the rotary nozzle 550d, which is shaft-sealed with the O-ring 550e and the O-ring 550f, in a freely rotatable manner. Furthermore, an X-ring may be used instead of the O-ring 550f. Thereby, the torque required for the rotational driving of the rotary nozzle 550d can be reduced. In addition, it is possible to more reliably prevent the rotation nozzle 550d from being fixed. As a result, it becomes possible to use a small-sized, low-torque motor for the dispersion nozzle driving section 550a.

In addition, the rotary nozzle 550d is rotationally driven by being fitted to the dispersion nozzle driving portion 550a through the shaft 550n.

As described above, the dispersion nozzle 550 according to this embodiment can be configured to operate as follows.

First, the washing water or the washing foam generated in the foam generating part 560 shown in FIG. 6 is supplied from the inlet flow path 550b of the main body 550c of the dispersion nozzle 550. The supplied washing water or washing foam is supplied into the rotary nozzle 550d from a plurality of inlet holes 550h cut out around the rotary nozzle 550d. Thereafter, the supplied washing water or washing foam is discharged from the outlet 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 spray nozzle 550 is disposed further to the right than the center of the body 200. The reason for this is that a cleaning nozzle (that is, a buttocks cleaning nozzle 831 and the like) that cleans a part of the human body is preferentially disposed at the center. Therefore, the dispersion nozzle 550 is not arranged at the center, but is arranged at either of the left and right sides. In addition, the above arrangement can of course be reversed.

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

Furthermore, in the following description, the ejection control in the rotating foam dispersion instruction issuing mode of the dispersion nozzle 550 when the user is in a non-seated state and the toilet seat is in a closed state will be described.

First, when the user 130 enters the toilet, the control unit 130 of the sanitary washing apparatus 100 detects the entry of a person into the room with the human body detection sensor 450. At this time, the control unit 130 is set to a rotation foam spreading instruction issuing (foam coating) mode. This mode is to rotate and drive the direction of the outlet 550u of the spreading nozzle 550 and spread the cleansing foam in the toilet. As a result, the control unit 130 enters the toilet foaming operation in the toilet 110. Then, the control unit 130 starts the operation of the water pump 516 shown in FIG. 6. In addition, the control unit 130 opens the on-off valve 530 a of the branch flow path 530.

In this case, the fluid regulating valve 517 for switching the flow paths of the hip washing nozzle 831, the vaginal 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 passes through the branch flow path 530 and the check valve 531 and the foam tank 532 constituting the foam generating part 560, and is supplied to the spray nozzle 550. The supplied washing water is discharged from the outlet 550u of the spray nozzle 550 toward the inner surface of the toilet or the hip washing nozzle 831 and the like.

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

Further, as shown in FIG. 11, the distance from the outlet 550u of the spray nozzle 550 to the inner surface of the toilet is different depending on the rotation angle direction of the spray nozzle 550.

That is, when the rotation angle of the dispersion nozzle 550 arranged at the above-mentioned position is changed, as shown in FIG. 11, when the rotation angle of the outlet 550u of the dispersion nozzle 550 is 160 °, the outlet 550u is passed to the toilet. The distance to the inner surface becomes the longest (far). On the other hand, when the rotation angle of the outlet 550u is 340 ° (equivalent to the position rotated by 180 ° from the above-mentioned 160 °), the distance from the outlet 550u to the inner surface of the toilet becomes the shortest (close).

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

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

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

At this time, the control unit 130 has a form as shown in FIG. 12. In response to the rotation angle of the discharge outlet 550u of the dispersion nozzle 550, the output of the water pump 516 is changed to a range from "high" to "low" while being discharged and washed Net foam etc.

Specifically, in the vicinity of the rotation angle of 160 °, which is the longest (far) distance from 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. 12. . On the other hand, the control unit 130 sets the output of the water pump 516 to be small near the rotation angle of 340 °, which is the shortest (close) distance to the inner surface of the toilet.

More specifically, the control unit 130 changes the output of the water pump 516 stepwise or continuously from “low” to “low” in a range of 0 ° to 160 ° as shown in FIG. 12. in". Similarly, the control unit 130 changes the output of the water pump 516 stepwise or continuously from "medium" to "low" within a range of 160 ° to 340 °. Accordingly, in accordance with the distance from the outlet 550u to the inner surface of the toilet, the entire surface of the inner surface of the toilet is covered to disperse the washing water or the washing foam to a predetermined height range.

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

That is, the control unit 130 controls the ejection amount (and ejection speed) of the washing water or foam 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) ).

More specifically, when the washing foam and washing water are discharged in front of the toilet which is the farthest distance from the outlet 550u of the spray nozzle 550, the output of the water pump 516 is set to "medium" and the stronger Spit out washing foam and water. Thereby, the washing foam and washing water can be sufficiently delivered to the inner surface in front of the toilet.

On the other hand, when washing foam or washing water is discharged behind the toilet closest to the outlet 550u of the spray nozzle 550, the output of the water pump 516 is set to "low" and is discharged with the weakest force Rinse with foam or water. With this, it is possible to prevent the occurrence of undesirable conditions such as the rebound of the washing foam or the washing water.

In addition, before use, the entire inner surface of the toilet is spouted with washing water or foam to form a water film or a foam film. Thereby, the adhesion of dirt during use to the inner surface of the toilet can be suppressed before it occurs.

In this embodiment, when the human body detection sensor 450 detects that the user enters the toilet, or when the user operates the dispersing switch 417 through the operation unit 210 or the remote control 400, the control unit 130 will The so-called toilet foam spreading in which the washing foam is distributed on the inner surface of the toilet before use is performed.

At this time, the control unit 130 is in the toilet while changing the output of the water pump 516 constituting the water discharge variable part when the toilet foam is distributed according to the signal of the toilet foam dispersion, as shown in FIG. 12. Spread cleansing foam on the surface. Specifically, the control unit 130 first causes the spray nozzle driving unit 550a to rotate forward (for example, clockwise), and moves the nozzle 550u of the rotating nozzle 550d from the back of the toilet to the front of the toilet and then moves toward the back of the toilet Spread cleansing foam on one side. In addition, the control unit 130 then reverses the spray nozzle driving portion 550a (for example, counterclockwise), and spreads while moving the direction of the outlet 550u of the rotating nozzle 550d in a direction from the back of the toilet, past the front of the toilet, and back to the back of the toilet Wash the foam. That is, the following steps are performed to cover the inner peripheral surface of the toilet to rotate the discharge port 550u of the rotary nozzle 550d in the forward and reverse directions, and to spread the washing foam by at least one revolving operation.

At this time, the control unit 130 controls the output of the water discharge amount variable unit so that the washing foam reaches the edge 110 a of the toilet 110. Thereby, the washing foam can be spread on almost the entire circumference (including the entire circumference) of the inner surface of the toilet before use. As a result, a foam film can be formed on the inner surface from the front to the back of the toilet, and adhesion of dirt can be suppressed before it occurs.

In this case, as shown in FIG. 12, the control unit 130 should control the output of the variable water discharge amount portion of the spray nozzle driving portion 550 a in the normal rotation to a lower output than that of the spray nozzle driving portion 550 a in the reverse rotation. Come spit out the cleansing foam.

As long as the output of the variable amount of water discharge is reduced, the force to spit out the cleaning foam will be weakened, so the cleaning foam can be spread to the closer (position) by the spray nozzle. Specifically, as shown by the scattered movement trajectory TF shown by the dotted line in FIG. 11, in the forward rotation (clockwise direction), the direction of the outlet 550u of the rotary nozzle 550d is closer to the edge 110a of the toilet 110. Washing foam is spread on the side of the inner draught surface 110b.

On the other hand, as long as the output of the variable water discharge amount is increased, the force of discharging the cleaning foam will be increased, so the cleaning foam can be spread to a greater distance (position) by the spray nozzle. Specifically, as shown by the scattered movement trajectory TR shown by the dotted line in FIG. 11, in the reverse rotation (counterclockwise direction), the direction of the outlet 550u of the rotary nozzle 550d is directed toward the edge 110a of the toilet 110. Spread cleansing foam from the side.

Thus, at the initial stage of the spreading (forward rotation), firstly, the draught surface 110b on the upper part of the outlet 115 of the toilet 110 can be covered by washing foam. Thereafter, during reversal, the washing foam may be spread over almost the entire circumference of the inner surface of the toilet 110 near the edge 110a. As a result, a foam film is formed on the draught surface 110b from the front to the back of the toilet, and the inner surface from the draught surface 110b to the edge 110a, and the adhesion of dirt can be effectively suppressed.

In this embodiment, as shown in FIG. 2, FIG. 9, FIG. 10, and FIG. 11, the spray nozzle 550 is disposed at a position in front of the main body 200 which is placed on the toilet 110. That is, the spray nozzle 550 is provided on a more front side than the front end position of the nozzle device 800 in which the nozzle device 800 is protruded from the storage position of the washing nozzle 831 to the hip washing or genital washing. Device for washing human body in a clean position. Thereby, during the rotation driving, the direction of the outlet 550u of the rotary nozzle 550d can be directed toward the rear of the toilet 110 to spread the washing foam into foam. As a result, a foam film of cleansing foam can be formed on the inner surface from the front to the back of the toilet 110, and the adhesion of dirt can be suppressed.

Moreover, in the above description, although the configuration which controls the change of the output of the water pump 516 which constitutes a water discharge amount variable part when the rotating foam is disperse | distributed to a toilet bowl is demonstrated, as an example, it demonstrates, It is not limited to this. For example, when rotating the foam, the output of the water pump 516 is not changed, and the spray nozzle 550 is configured as described below. A foam film may be formed on the inner surface from the front to the back of the toilet to prevent 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 tilted in the front-rear direction and the left-right direction and is installed in the main body 200. Specifically, the rotation axis Ax of the spray nozzle 550 is arranged in the front-rear direction so that the spray nozzle 550 faces downward and inclines toward the front side of the toilet 110. In addition, the rotation axis Ax of the spray nozzle 550 is arranged in a left-right direction so that the spray nozzle 550 faces downward, and is inclined toward the cleaning nozzle 831 side disposed at the center portion of the main body 200. With the configuration of the rotation axis Ax described above, when the discharge outlet 550u of the dispersion nozzle 550 faces the toilet 110 in which the distance to the dispersion position becomes longer, the position of the discharge outlet 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 distributed to the vicinity of the edge 110 a in front of the toilet 110.

On the other hand, when the discharge outlet 550u of the spray nozzle 550 is directed toward the rear of the toilet 110 with the distance to the spread position approaching, the position of the discharge outlet 550u becomes lower. Therefore, as shown in the discharge port direction AcB of FIG. 9, the cleaning foam can be discharged in an obliquely downward direction.

When the distance to the spreading position is to the right of the toilet 110 and the outlet 550u is advancing from the rear to the front, the direction of the outlet 550u is gradually changed from the outlet direction AcB to the outlet direction AcA. The ground becomes high. As a result, the washing foam can be distributed along the adjacent portion of the right edge 110a of the toilet 110. Further, when the distance to the spreading position is to the left of the toilet 110 which is gradually approaching and the outlet 550u is advancing from the front to the rear, the direction of the outlet 550u is changed from the outlet direction AcA to the outlet direction AcB. And gradually lower.

That is, when the rotating foam is dispersed, the dispersion nozzle driving unit 550a is rotationally driven around the rotation axis Ax to be dispersed in a direction such that the direction of the discharge outlet 550u of the rotary nozzle 550d is from the discharge outlet direction AcB to The discharge direction AcB of the discharge direction AcA was obtained. At this time, as described above, the distance from the discharge port 550u to the inner surface of the toilet 110 changes with the rotation of the spray nozzle 550. However, by arranging the rotation axis Ax of the spray nozzle 550 at an angle, it is possible to spray and wash while changing the height position of the spray outlet 550u of the spray nozzle 550 as shown in the discharge outlet direction AcA and the discharge outlet direction AcB with rotation. Net foam. Therefore, it is possible to form a foam film on the inner surface of the close edge 110a from the front to the back of the toilet 110 along the scattering movement track TR indicated by the left-handed dotted arrow in FIG. 11. As a result, the entire inner surface from the front to the back of the toilet 110 can be covered, and the adhesion of dirt can be suppressed.

According to the above-mentioned configuration, when the rotating foam is dispersed, it is possible to spit out the cleansing foam with a fixed output without changing the output of the water pump 516. Therefore, when the right-handed rotating foam is dispersed, the same trajectory as the spreading movement trajectory TR indicated by the left-handed dotted arrow shown in FIG. 11 can also be used to advance in the opposite direction and spread the cleansing foam.

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

In addition, the height position of the discharge outlet 550u of the dispersion nozzle 550 is set to a lower position than the upper end surface 110c of the toilet 110 at any rotation position.

Furthermore, in the above description, although the example of the forward rotation is the right-handed rotation when viewed from above in FIG. 11 and the reverse rotation is the left-handed rotation, it is not limited to this. For example, a forward rotation may be set to a left-handed rotation, and a reverse rotation may be set to a right-handed rotation. That is, the direction in which the discharge nozzle 550u of the dispersion nozzle starts to rotate during the dispersion is referred to as a forward rotation, and the direction of the return is referred to as a 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 outlet 550u of the spray nozzle 550. Thereby, it is possible to spit out the washing water or the washing foam from the spray nozzle 550 to the front, side, and back of the inner surface of the toilet 110 with different distances, and deliver it reliably. As a result, a water film or a foam film can be formed in a wide range of the inner surface of the toilet 110 to suppress the adhesion of dirt.

Furthermore, in the above embodiment, the description is made by using the configuration in which "high" and "low" are set based on the average level "medium" of the output of the water pump 516, but it is not limited to this. For example, the average level "medium" of the output of the water pump 516 may be set higher or lower to change the reference level. At this time, it is desirable to provide a level switch for adjusting the average level on the operation unit 210 or the remote control 400. Thereby, even when the size and the like of the toilet 110 provided with the sanitary washing device 100 are different, it is possible to spit out the washing water or washing foam to the entire circumference of the inner surface of the toilet. In addition, 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 embodiment, the control unit 130 is described as an example of the discharge control in which the output of the water pump 516 is changed in accordance with the rotation angle of the discharge outlet 550u of the dispersion nozzle 550, but it is not limited to this. . For example, in addition to changes in the output of the water pump 516, the control unit 130 may control the rotation speed of the dispersion nozzle driving unit 550a to be changed in accordance with the rotation angle of the discharge port 550u.

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

However, when the outlet 550u of the spray nozzle 550 is rotated at a fixed rotation speed, the distance to the inner surface of the toilet is far away, and the dispersion density of the washing foam and the washing water becomes thinner. On the other hand, when the distance to the inner surface of the toilet is relatively short, the dispersion density of the washing foam and the washing water will become denser.

Therefore, in the present embodiment, the rotation speed of the spray nozzle 550 may be changed by the spray nozzle driving unit 550a in accordance with the rotation angle of the discharge port 550u. Thereby, the entire circumference of the inner surface of the toilet 110 can be spread, and the washing water or the washing foam can be distributed at an even distribution density.

Furthermore, even when the output of the water pump 516 is changed and the washing foam and the washing water are dispersed, the dispersion density of the washing foam and the washing water can be made uniform to some extent.

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

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

On the other hand, when the rotation speed is fixed, the washing foam or washing water discharged near the rotation angle of 340 °, which is the closest distance from the outlet 550u of the spray nozzle 550 (even after the device 110), will collect The density of the dispersion becomes dense. Therefore, the rotation speed of the dispersion nozzle 550 is set to the fastest. Thereby, the time taken for the discharge port 550u of the dispersion nozzle 550 to pass through the adjacent portion behind the toilet is shortened. As a result, the dispersion density of the cleaning foam can be reduced.

That is, the distribution of the washing water or the washing foam dispersed on the inner surface of the toilet can be formed uniformly (elimination of gradation) by changing the rotation speed. Therefore, by forming a non-uniform foam film, the entire circumference of the inner surface of the toilet can be covered, and the adhesion of dirt can be more effectively suppressed.

As described above, the control section 130 changes the rotation speed of the spray nozzle driving section 550a according to the rotation angle of the discharge outlet 550u of the spray nozzle 550. For example, when the direction of the outlet 550u of the spray nozzle 550 is a rotation angle toward the front of the toilet with a longer distance to the inner surface of the toilet, the rotation speed of the spray nozzle driving portion 550a is set to gradually decrease (lower speed) . On the other hand, when the direction of the outlet 550u is a rotation angle toward the back of the toilet with a shorter distance from the inner surface of the toilet, the speed of the spray nozzle driving unit is gradually increased (higher). With this, the washing water or the washing foam can be uniformly discharged without unevenness in the distribution density of the toilets at different distances in front, side, and rear. As a result, a water film or a foam film uniformly formed on the inner surface of the toilet can effectively suppress the adhesion of dirt.

In addition, in this embodiment, the control unit 130 controls the human body detection sensor 450 to detect the entry of a person, that is, to execute the distribution of the washing water or the washing foam from the spray nozzle 550 to the inner surface of the toilet in advance. The so-called toilet foam spreads. Specifically, the control unit 130 controls the rotary nozzle 550d to be rotated and driven back and forth at least once by the spray nozzle driving unit 550a, for example, and automatically stops after the foam is sprayed. Therefore, before the user uses the sanitary washing device, a water film or a foam film can be formed on the inner surface of the toilet in advance. As a result, the adhesion of dirt to the inner surface of the toilet during use can be effectively suppressed.

In the above description, the example is described in which the spray nozzle 550 is rotated back and forth once to spread the washing foam or the washing water before use, but it is not limited to this. For example, the number of times that the scattered washing foam and washing water can be sufficiently spread over the inner surface of the toilet can be any number. In this case, the number of round trips when the toilet foam is spread is preferably configured so that the user can select and set the operating unit 210 or the remote control 400.

Moreover, in the above-mentioned embodiment, the rotation direction of the dispersion nozzle 550 is not specifically mentioned. As shown in FIG. 12, it is a structure provided so that the rotation nozzle 550d may rotate back and forth once. The reason is that in the case where the rotating nozzle 550d of the spray nozzle 550 is configured to rotate the entire circumference only in either the right or left direction, the spraying direction of the washing water or the washing foam is often made. The ground becomes the same direction. Therefore, in this embodiment, the washing foam or the washing water is distributed to the inner surface of the toilet by rotating it back and forth once and rotating it in both directions. This makes it possible to further reduce the occurrence of so-called scattered missing portions. Therefore, it becomes possible to spread the washing foam and washing water more evenly throughout the inner surface of the toilet. As a result, it is possible to suppress the adhesion of dirt to the inner surface of the toilet with a small number of times (time) of spreading. In addition, the above-mentioned back-and-forth rotation is not limited to one back-and-forth rotation, and may be set to plural back-and-forth such as two back-and-forth or three 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 a rotation angle of 0 ° corresponding to the rear side of the toilet 110 to a rotation angle of 340 °. stop for a while. After that, the rotating nozzle 550d is reversed from the rotation angle of 340 ° to the rotation angle of 0 ° (for example, counterclockwise), and stops after rotating back and forth once.

In this case, it is desirable to provide, for example, a mechanical stopper (i.e., a rotation restricting portion) for limiting the rotatable range of the rotating nozzle 550d of the dispersion nozzle 550 to a range of a rotation angle of 0 ° to a rotation angle of 340 °. (Not shown).

Specifically, the rotation restricting portion is configured by, for example, a protrusion formed on a part of the outer periphery of the rotating nozzle 550d and a rotation restricting wall of the main body 550c. With this configuration, when the protrusion rotates to physically contact the rotation restricting wall, the operation of the rotary nozzle 550d to be rotated is restricted. That is, the motor constituting the dispersion nozzle driving section 550a slips and idles by abutting. Thereby, the rotation nozzle 550d can restrict the rotation beyond the rotatable range.

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

In addition, the control unit 130 may always recognize the position where the protrusion of the rotary nozzle 550d of the dispersion nozzle 550 abuts the rotation restriction portion as the origin of the rotation position of the dispersion nozzle driving unit 550a. Therefore, it is possible to prevent the origin from being shifted due to the back-and-forth operation of the rotary nozzle 550d. 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, it is possible to reduce deviations such as positional deviation from a predetermined position on the inner surface of the toilet. As a result, it is possible to disperse the washing foam and the washing water from the ejection outlet 550u of the dispersing nozzle 550 at a proper position on the inner surface of the toilet at an appropriate ejection output and rotation speed.

In addition, although the structure which restricts the rotation range of the dispersion nozzle 550 as an example was demonstrated in the above, it is not limited to this. When the positional deviation of the origin of the spray nozzle 550 is not a problem, the forward and reverse rotation of the spray nozzle 550 may be simply performed by the spray nozzle driving unit 550 a. This eliminates the need for a rotation restricting portion, and enables various operations of rotating the nozzle 550d such as forward and reverse rotation or unidirectional rotation. As a result, the rotary nozzle 550d can be operated more appropriately in accordance with conditions such as dirt on the inner surface of the toilet. In this case, it is preferable to set the origin of the dispersion nozzle 550 to a neighboring portion with a rotation angle of 160 ° to be reversed, and control it to gradually reduce the rotation speed at the neighboring portion. This makes it possible to reduce the load applied when the spray nozzle driving section 550a is rapidly reversed.

Hereinafter, the structure of the foam generating part 560 of the sanitary washing apparatus of this embodiment is demonstrated with reference to FIG. 6. FIG.

As shown in FIG. 6, the foam generating part 560 is connected to the branch flow path 530 through the on-off valve 530 a and the check valve 531. The branch flow path 530 is a water pump 516 and a fluid regulating valve 517 constituting a variable water discharge portion. The flow path between the washing water supply flow paths 690 diverges. Then, the on-off valve 530 a is opened and closed to supply the washing water to the foam generation unit 560 through the branch flow path 530.

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

A spray nozzle 550 is connected to the foam tank 532 downstream. The foam tank 532 is connected to the lotion tank 533 through which the lotion pump 534 is supplied.

The foam box 532 is also connected to an air pump 535. The air pump 535 sends air into the foam tank 532 to cause it to produce clean foam and the like. In addition, the air pump 535 supplies the washing water and the generated washing foam to the spray nozzle 550.

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

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

Next, the control unit 130 drives the air pump 535 to supply air into the foam tank 532. As a result, a cleaning foam is generated in the foam tank 532. The generated cleansing foam is supplied to the spray nozzle 550, and is discharged from the outlet 550u of the rotary nozzle 550d to the inner surface of the toilet.

At this time, according to the increase or decrease of the output of the water pump 516 and the air pump 535, the amount of the washing water or the washing foam discharged from the dispersion nozzle 550 and the force of the discharge (the discharge speed and discharge) will be increased or decreased. Pressure). Thereby, as described with reference to FIG. 11, the washing foam and the washing water can be evenly distributed on the inner surface of the toilet. That is, the air pump 535 of the foam generation part 560 also functions as a water discharge amount variable part similarly to 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 is described as an example, but it is not limited to this. 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 unit 560 of this embodiment includes a foam tank 532 between the on-off valve 530 a and the spray nozzle 550. The foam tank 532 is supplied with a lotion from a lotion tank 533 and generates a washing foam. It has the following structure: The generated cleaning foam is discharged toward the inner surface of the toilet from the outlet 550u of the spray nozzle 550.

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

In addition, by using a washing foam containing a lotion, it is possible to effectively suppress odors generated by dirt and the like. In addition, the wash foam can give the user a visually clean impression. As a result, user comfort is further enhanced.

In addition, in the above-mentioned embodiment, although the configuration in which the washing water or the washing foam is distributed on the inner surface of the toilet is detected when the human detection sensor 450 detects the entry of a person, the description is given by way of example. It is not limited to this. For example, a configuration may be adopted in which a person operates the dispersion switch 417 provided in the operation unit 210 or the remote control 400 to perform the dispersion. With this, even when the toilet is not used as a sanitary washing device, when the dirt on the inner surface of the toilet is concerned, the inner surface of the toilet can be dispersed with washing foam containing a lotion to remove the dirt. In addition, it is possible to prevent the formation of stubborn dirt on the draught surface 110b or the like before it occurs due to drying. That is, by operating the dispersing switch 417 by the user, a foam film formed of a washing foam containing a lotion can be formed on the inner surface of the toilet at any time. As a result, the inner surface of the toilet can be kept clean.

Moreover, in the above-mentioned embodiment, the user may be provided with the use of a spreading selection switch (not shown) of the operation unit 210 or the remote control 400 in advance to arbitrarily select one of washing water and washing foam to be distributed on the inner surface of the toilet. Composition. Thereby, it is possible to arbitrarily select whether or not it is necessary to disperse in accordance with the occurrence of dirt, odor, and the like on the inner surface of the toilet. As a result, useless use of the lotion can be suppressed, and the cost performance can be improved.

Moreover, in the said embodiment, the control part 130 may be set as the structure which has the washing-command issuing mode which can be selected by the switch button of the operation part 210 or the remote control 400.

In this case, at the time of the washing instruction issuing mode, the control unit 130 is first opened in a state where the lotion of the lotion tank 533 of the foam generating unit 560 can be stopped and the lotion pump 534 of the foam tank 532 is stopped. On-off valve 530a. As a result, the water pump 516 sends the washing water to the foam tank 532. The supplied washing water is supplied from the foam tank 532 to the spray nozzle 550 and is discharged into the toilet 110.

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

That is, during the washing operation in the washing instruction issuing mode, the lotion pump 534 is in a stopped state. Therefore, no detergent is supplied to the foam tank 532, and only the washing water is delivered. Thereby, the path from the foam tank 532 to the spray nozzle 550 is washed by the supplied washing water. At the same time, the washing water having been washed in the path can be sprayed from the spray 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 along with the washing of the path.

Furthermore, in the washing operation in the washing instruction issuing mode, washing is usually performed with washing water without temperature control. However, the temperature of the washing water may be heated by the heat exchanger 700 to, for example, about 40 ° C. and supplied to perform a washing operation. Thereby, the solubility of the remaining lotion and the like in the washing water can be increased, and a more excellent washing effect can be obtained.

In addition, the above-mentioned washing instruction issuing mode may be configured such that the user can operate the washing switch 223 of the operation unit 210 to arbitrarily perform washing on the path or the inner surface of the toilet.

Specifically, as shown in FIG. 4, a washing lamp 223 a such as an LED is provided in the vicinity of the washing switch 223 of the operation unit 210 set to the washing instruction issuing mode. When a predetermined time e.g. 20 days has elapsed since the previous washing was performed, the control unit 130 causes the washing lamp 223a to automatically blink. Thereby, forgetting to wash can be prevented, and the occurrence of blockages such as paths can be prevented beforehand.

In addition, when the cleaning foam is spread on the inner surface of the toilet, the control unit 130 can also use air to control the rotation of the outlet 550u of the spray nozzle 550 in the same manner as the output operation of the water pump 516 shown in FIG. 12. The output of Pu 535 was changed to distribute cleansing foam from the outlet 550u. Thereby, the washing foam can be spit out to be effectively delivered to the front, the side, and the back of the toilets with different distances. As a result, it is possible to form a foam film on the entire inner surface of the toilet, and to suppress the adhesion of dirt.

Specifically, as explained with reference to FIG. 11, the distance from the outlet 550u of the spray nozzle 550 to the inner surface of the toilet is the longest (distant) rotation angle of 160 °, and the control unit 130 controls 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 outlet 550u to a distance can be enhanced.

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

That is, the pressure of the air discharged from the air pump 535 is adjusted in accordance with the distance from the outlet 550u of the spray nozzle 550 to the inner surface of the toilet. As a result, it is possible to spit out the cleansing foam uniformly on the inner surface of the toilet.

Further, in the embodiment described above, a configuration may further be provided that includes a dirt detection unit (not shown) that detects dirt in the toilet with an image element such as a CCD (Charge Coupled Device). At this time, based on the detection result of the dirt detection unit, the control unit 130 drives the spreading nozzle 550 so as to move back and forth around the portion where dirt remains, and spreads the cleaning foam in a concentrated manner. This can effectively remove the dirt attached to the inner surface of the toilet. In addition, in addition to the method of moving back and forth only in the dirt portion, the rotation speed of the discharge port 550u passing through the spray nozzle 550 of the dirt portion may be rotated and driven at a lower speed. In addition, it is also possible to make 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. Thereby, the same effect can be obtained. <4> Dispensing control and function and action by the spray nozzle in the open and non-seated state of the toilet seat

13A and 13B, when a user is urinating, when the user is not seated in the toilet seat 300 and the toilet seat 300 is almost vertically opened, the dispersion when the user operates the dispersion switch 417 The nozzle discharge control will be described.

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

Furthermore, in the item <3>, it is explained that the foam is cleaned while driving the direction of the outlet 550u of the spray nozzle 550 in accordance with the rotation foam spreading instruction issuing (foam coating) mode of the control unit 130. Spiral foam spread in the toilet.

In this item <4>, it is explained that according to the fixed foam spreading instruction issuing (spatter suppression) mode of the control unit 130, the cleansing foam is spread into the toilet as it is while the direction of the outlet 550u of the spray nozzle 550 is fixed .

That is, when a male is urinating, the fixed foam is spread in a state where the user is not seated in the toilet seat 300 and the toilet seat 300 is opened almost vertically.

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

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

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

In the above state, the user presses the manual splash suppression switch 434 of the operation section 210 or the remote control 400. The manual splash suppression switch 434 of the operation unit 210 is not particularly shown.

Accordingly, the control unit 130 first drives the spray nozzle driving unit 550a, and rotates the direction of the discharge port 550u of the spray nozzle 550 to a position toward the rear of the toilet as shown in FIG. 13B. Next, the driving of the dispersion nozzle driving section 550a is stopped. In the case of this embodiment, as shown in FIG. 13A, the rotation angle of the discharge port 550u is stopped at a position around 20 °, for example. With this, the direction of the outlet 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 variable portion to a “high” output. Then, in the direction indicated by the arrow in FIG. 13B, the washing water or the washing foam is discharged from the spray nozzle 550 toward the rear of the toilet 110 for a predetermined time. In this embodiment, the predetermined time is set to, for example, 8 seconds.

At this time, the discharge port 550u of the scattering nozzle 550 stops downward in the direction of the angle α with respect to the rotation axis Ax of the scattering nozzle 550 shown in FIG. 9. Therefore, the cleaning foam and the like are discharged from the discharge port 550u of the dispersion nozzle 550 in a state of being stopped in the direction shown in the discharge port direction AcB of FIG. 9.

That is, after the direction of the outlet 550u of the spray nozzle 550 is rotated and driven behind the toilet, the control unit 130 controls the water pump 516 to a "high" output to spit out cleansing foam and the like. Thereby, the water surface above the discharge port 115 in the toilet bowl and the upper part of the water line in the toilet bowl will be quickly covered by the washing foam flowing down from the rear. As a result, by washing the foam, it is possible to suppress the spread of odor accompanying excretion such as urination and the adhesion of dirt near the draught surface 110b of the toilet 110.

In addition, when the excreted urine is dropped near the water surface in the toilet 110, the washing foam covering the water surface can provide a cushioning effect. Thereby, it is possible to suppress a rebound from the surroundings outside the toilet 110. That is, a large amount of washing foam and the like are quickly spread in a direction in which the spray nozzle 550 has been fixed to form a foam film on the upper surface of the water in the toilet 110. This can prevent the urine from flying out of the toilet 110 due to bouncing or the like.

In addition, in this embodiment, when the fixed foam spreading instruction issuing mode (spatter suppression mode) is set by the operation of the user's manual splash suppression switch 434, the outlet 550u faces the back of the toilet. At this position, the rotational driving of the dispersion nozzle driving section 550a is stopped. Although the configuration in which the control unit 130 controls the spouting amount variable unit 516 with the "high" output after the stop is made to exemplify that the washing foam is discharged toward the back of the toilet, it is not limited to this. For example, the position of the spreading nozzle 550 for spreading the cleaning foam may be any one of the front side, the center, the rear side, and the left and right sides of the toilet near the discharge port 115 of the toilet 110. That is, as long as the washing foam is discharged, and the draught surface 110b and the upper part of the waterline of the toilet bowl 110 are quickly covered with the washing foam in a short time, such as a few seconds, it is sufficient. This can suppress splashing or scattering of urine. In addition, the adhesion of dirt to the vicinity of the waterline in the toilet bowl 110 and its upper portion can be more surely suppressed.

Moreover, in the present embodiment, although in the fixed foam spreading instruction issuing mode, the control unit 130 discharges the washing foam from the water discharge amount variable unit 516 toward the back of the toilet with a "high" output as shown in FIG. 13A The structure of the etc. is described as an example, but it is not limited to this. For example, the output of the water discharge amount variable unit 516 may be discharged with a "medium" output.

As described above, the sanitary washing device according to this embodiment includes the body 200 provided on the toilet 110, a washing nozzle 831 for washing the human body, a foam generating part 560 for generating washing foam, and the washing water or The spray nozzle 550 for washing the foam, and the discharge amount variable section 516 that changes the flow rate of the washing water sent to the spray nozzle. In addition, the sanitary washing apparatus further includes a spray nozzle driving unit 550a that drives the discharge nozzle 550u of the spray nozzle, an on-off valve 530a that opens and closes the water path to the spray nozzle, a control unit 130, and an operation unit 210 that instructs and sets the control unit. . In addition, the control unit 130 includes the following control operations: a rotation foam distribution instruction issuing mode, which rotates and drives the discharge nozzle 550u toward the spray nozzle, and spreads the cleansing foam into the toilet; and a fixed foam distribution instruction release mode, The direction of the outlet 550u of the spray nozzle is fixed, and the cleansing foam is spread into the toilet as it is.

According to this configuration, when the toilet foam is distributed in the rotation foam distribution instruction issuing mode, the control unit 130 spreads the cleansing foam from the spray nozzle 550 into the toilet while rotating and driving the direction of the outlet 550u of the spray nozzle. Ground delivery. Thereby, the inner surface from the front to the back of the toilet is formed by washing the foam to form a foam film, and the adhesion of dirt on the inner surface of the toilet and near the waterline can be suppressed.

On the other hand, when the toilet foam is distributed in the fixed foam distribution instruction issuing mode, the control unit 130 spreads the cleansing foam into the toilet as it is, with the direction of the outlet 550u of the spray nozzle fixed. In addition, a foamed film of washed foam was quickly formed on the upper surface of the water in the toilet. Thereby, the water surface in the upper part of the discharge opening in a toilet can be covered quickly with the foamed film of a wash foam. As a result, it is possible to suppress the spread of odor during urination or the rebound from the water surface when the urine of the male drops while urinating due to the buffer effect of the cleansing foam.

Here, the effect of suppressing the scattering of urine formed by washing foam will be described with reference to the verification results shown in FIG. 25.

FIG. 25 is a diagram showing a verification result of the splash suppressing effect of foam spread in the fixed foam spread instruction issuing mode of the sanitary washing device. The vertical axis of FIG. 25 shows the height (thickness) of the washing foam covering the draught surface, and the horizontal axis shows the elapsed time.

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

In addition, it was confirmed that when the foam height is about 10 mm or more in the initial stage of the spreading, the effect of suppressing the scattering of urine or the like from the bedpan surface of the toilet bowl 110 to the outside becomes significant. In this case, it is understood that the suppression effect is also reduced with the lapse of time.

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

According to the above verification results, it is preferable that the lower limit of the height of the foam on the water surface in the toilet formed by the foam dispersion is 5 mm or more and the upper limit is 50 mm or less. In particular, a range of 10 mm to 50 mm is more preferable. In addition, the upper limit of 50 mm is a predetermined value based on the height of the foam in the sanitary washing device used in the verification experiment when the user is already seated in the toilet seat so that the accumulated foam does not stick to the hips. Therefore, in different sanitary washing devices, it is of course possible to change the upper limit setting according to the size and shape of the toilet and the toilet seat.

The sanitary washing device of the present embodiment is installed on the main body 200 by rotating the rotation axis Ax of the discharge port 550u of the rotary nozzle 550d of the spray nozzle 550d that is rotationally driven in the front-rear direction and the left-right direction. In addition, the inclination in the front-rear direction is arranged with the lower side of the spray nozzle 550 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 with respect to the rotation axis Ax such that the lower side of the spray nozzle 550 faces washing The nozzle 831 is arranged obliquely.

According to this configuration, when the washing foam is distributed to the toilet foam of the toilet 110, when the discharge opening 550u of the distribution nozzle 550 is directed toward the spreading position in front of the toilet which is further away, the discharge outlet 550u is directed. Becomes high. On the other hand, when the ejection outlet 550u of the spray nozzle is directed toward the spreading position behind the closet of the toilet, the direction of the ejection outlet 550u becomes lower. This makes it possible to spread the washing foam while changing the height of the discharge nozzle 550u of the spray nozzle in accordance with the distance from the discharge nozzle 550u of the spray nozzle to the inner surface of the toilet. Therefore, without changing the output of the water pump 516, the washing foam can be spread to the inner surface from the front to the back of the toilet to form a foam film. As a result, adhesion of dirt to the inner surface of the toilet can be suppressed.

In the sanitary washing device of this embodiment, when the toilet foam is spread from the spray nozzle 550 to the toilet 110, the control unit 130 causes the spray nozzle driving unit 550a to rotate forward so that the direction of the discharge port 550u passes behind the toilet. The front of the toilet rotates to the back of the toilet. After that, the control unit 130 reverses the spray nozzle driving unit 550a to rotate the direction of the outlet 550u so that it passes from the back of the toilet to the front of the toilet and returns to the back of the toilet. That is, the control unit 130 is controlled to perform a step motion of rotating the foam spread by at least one back and forth rotating motion.

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

In addition, the sanitary washing apparatus of this embodiment further includes a human detection sensor 450 that detects a user's entry and exit into the toilet. When the human body detection sensor 450 detects that the user enters the toilet, the control unit 130 spreads the rotating foam toward the inner surface of the toilet through at least one revolving motion.

According to this configuration, when the human body detection sensor 450 detects the user's entry into the toilet, it can be driven to rotate back and forth in the direction of the outlet 550u of the spray nozzle at least once to spread the inner surface of the toilet. Sponge foam for washing foam. Thereby, a foam film can be formed on the inner surface of the toilet before use, so that the adhesion of dirt can be suppressed before it occurs.

In addition, the sanitary washing device according to this embodiment includes a foam tank 532 that conveys washing water by the discharged water amount changing unit 516 by opening the on-off valve 530a by the control unit 130, and supplies a lotion from the detergent tank 533 to the foam. The lotion pump 534 of the tank 532 and the air pump 535 supplying air to the foam tank. Further, the control unit 130 controls to discharge the washing water or the washing foam of the foam tank 532 from the spray nozzle 550.

With this configuration, not only water or warm water can be discharged onto the surface of the cleaning nozzle 831 or the inner surface of the toilet, but also a cleaning foam containing a lotion can be discharged. Thereby, the cleaning effect and the effect of suppressing the adhesion of dirt can be improved. In addition, it is possible to suppress the spread of odor by a washing foam containing a lotion. As a result, it is possible to provide the user with a visually clean feeling and a comfortable feeling during use.

The control unit 130 of the sanitary washing device according to this embodiment has a washing instruction issuing mode. Further, in the washing instruction issuing mode, the control unit 130 opens the on-off valve 530a in a state where the lotion of the lotion tank 533 of the foam generating unit 560 can be supplied to the lotion pump 534 of the foam tank 532, Meanwhile, the washing water is sent to the foam tank 532 by the discharge water amount variable unit 516 and is discharged from the spray nozzle 550.

With this configuration, the path from the foam tank 532 to the spray nozzle 550 can be washed with washing water. Thereby, clogging of the path or the spray nozzle 550 due to the fixation of the lotion, and poor rotation of the spray nozzle 550 due to the fixation of the lotion can be prevented. The inner surface of the toilet can be washed with washing water.

In the present embodiment, the configuration using a motor is described as an example of the spray nozzle driving unit 550a, but the invention is not limited to this. A configuration may also be adopted in which the spray nozzle 550 is rotated by the reaction when the cleaning foam is discharged from the spray outlet 550u of the spray nozzle 550. This makes it possible to simplify the configuration and suppress power consumption.

In addition, in this embodiment, although the structure which has one dispersion nozzle 550 was demonstrated as an example, it is not limited to this. For example, a plurality of spraying nozzles may be provided in the following form: a spraying nozzle that sprays cleaning foam near the edge 110a of the toilet 110, and a spraying nozzle that sprays cleaning foam near the outlet 115 of the toilet 110 Wait. At this time, the plurality of scattering nozzles can be rotated independently, or they can be rotated in conjunction. Thereby, the washing foam can be spread to the inner surface of the toilet in a short time.

In addition, in this embodiment, although the structure provided with the one discharge opening 550u in the dispersion nozzle 550 is demonstrated as an example, it is not limited to this. For example, the spray nozzle 550 may be provided with a plurality of spouts, such as a spout for spreading cleansing foam near the edge 110 a of the toilet 110 and a spout for spreading cleansing foam near 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.

In the present embodiment, the configuration is described by taking the spray nozzle 550 to distribute the cleaning foam at two places near the edge 110a of the toilet 110 and the outlet 115 of the toilet 110 as an example, but it is not limited to this. this. For example, in addition to the above, a configuration may also be adopted in which the cleaning foam is sprayed at a middle position (height) between the edge 110 a of the toilet 110 and the discharge port 115 with the spray nozzle 550. This can further reduce the occurrence of scattered missing portions.

Moreover, as shown in FIG. 10, FIG. 14, and FIG. 15, the sanitary washing apparatus of this embodiment is provided with the sleeve cover 250 integrally provided in the side part of the main body 200 so that it may protrude forward. The sleeve cover 250 has a sleeve cover 217 provided forward of the operation portion 210 disposed on the upper portion, and a lotion box 533 formed by a visible container, which is inside the sleeve cover 217 and is built in the foremost portion. . In addition, the sleeve cover 250 is provided at the front with a lotion liquid level confirmation window 216 that can confirm the lotion liquid level position of the lotion tank 533.

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

That is, the lotion tank 533 has a lotion injection port 537 provided with a lotion tank cover 536 above. The lotion tank 533 is arranged at the forefront of the operation part 210 of the sleeve cover 250 and is arranged at the position closest to the front of the toilet. Therefore, replenishment of the lotion liquid becomes easy. The sleeve cover 217 is provided further forward than the operation section 210. Thereby, when the user replenishes the lotion liquid to the lotion tank 533, it is possible to prevent the lotion liquid from spilling on the operation portion 210. As shown in FIGS. 14 and 15, the lotion injection port 537 is disposed at a position lower than the operation portion 210. Thereby, when the lotion liquid is replenished to the lotion tank 533, it is possible to more surely prevent the lotion from spilling on the operation portion 210.

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

With these configurations, even if a high pressure is applied from the lotion pump 534 to the lotion pump hose 561, it is possible to prevent the lotion pump hose 561 from expanding and breaking. Thereby, it is possible to stably proceed to spread the cleaning foam from the spray nozzle 550 into the toilet.

In addition, the lotion pump hose 561 is a double tube formed by covering the outside of an elastomer resin tube with a heat shrinkable tube, for example, but the material is not limited to this. That is, it is not particularly limited as long as it is a material that can prevent the expansion and rupture of the lotion pump hose 561 by a double tube structure. Thereby, the cleaning foam can be stably spread from the spray nozzle 550.

As shown in FIGS. 2, 15, and 16, the sanitary washing apparatus according to this embodiment includes a control unit 130, a spray nozzle 550, and a nozzle device in the main body 200, and the main body 200 is a main body cover. 202 covers the front of the rear body cover 201. The spray nozzle 550 is provided in a front portion of the rear body case 201, and the front and upper portions of the spray nozzle 550 are covered by the body cover 202. The lower outlet 550u of the spray nozzle 550 is configured to be open to the inner surface of the toilet.

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

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

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

However, when washing is performed in the above-mentioned washing instruction issuing mode, washing water without washing foam is discharged from the discharge port 550u of the spray nozzle 550. In this case, as shown by the two-dot chain line S in FIG. 16, there is a concern that the jet of the washing water is diffused and scattered. Therefore, there is a possibility that the washing water may be scattered to the outside of the toilet, thereby causing a bad condition such as the toilet floor being wetted.

Therefore, in this embodiment, as shown in FIG. 16, a scattering prevention portion 550z is provided on the main body cover 202. The scattering prevention portion 550z intercepts jets of washing water and the like in an upward direction exceeding the upper limit (flying out to the outside) from the discharge port 550u of the scattering nozzle 550, and drops it into the toilet. Thereby, the washing foam and washing water discharged from the spray nozzle 550 can be prevented from being sprayed to the outside of the toilet, and can be scattered into the toilet.

The scattering prevention unit 550z has a function for preventing the scattering of washing water and the like from the outside, as well as a function described below with reference to FIGS. 17 to 18.

Fig. 17 is a front view of a main body in the sanitary washing device. Fig. 18 is a side view of a main body in the sanitary washing device. The two-dot chain line shown in FIGS. 17 and 18 corresponds to a mounting surface such as a pedestal when the main body 200 is placed.

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

That is, when a construction worker or a user initially sets up a toilet, or cleans dirt near the lower part of the main body 200, etc., the main body 200 is removed from the toilet 110 and placed on a stand. The removed main body 200 may be temporarily placed on a stand or a floor, for example.

At this time, the scattering prevention portion 550z is protected so that the outlet 550u of the scattering nozzle 550 located below the mounting surface of the main body 200 does not contact the temporary stand or floor. This can prevent damage to the spray nozzle 550 beforehand. That is, as shown in FIG. 17 and FIG. 18, the scattering prevention portion 550z can prevent the contact between the outlet 550u of the scattering nozzle 550 and the pedestal by the scattering prevention portion 550z.

In addition, in the above-mentioned embodiment, although the structure in which the scattering prevention part 550z was formed in the main body cover 202 was demonstrated as an example, it is not limited to this. For example, the scattering prevention part 550z may be formed in the main body 550c of the scattering nozzle 550, or the like. This eliminates the need for a complicated large-sized molding die during the molding of the main body cover 202, and the main body cover 202 can be molded by a simple molding mold. In addition, the ejection opening 550u and the scattering prevention portion 550z can be configured with high position accuracy.

Next, a configuration in which the main body 200 is detachably attached to the toilet 110 will be described with reference to FIG. 19.

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

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

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

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

On the other hand, when the main body 200 is removed from the toilet 110, the main body release button 242 located beside (side) the main body 200 shown in FIG. 19 can be pushed deep (inside) with, for example, a finger. . Then, 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 body 200 and the toilet 110 can be detachably configured.

As shown in FIG. 19, a magnet 243 is embedded in a body fixing plate 240 made of resin such as polypropylene (PP), and a mounting sensor 244 is attached to the rear body cover 201. Thereby, the attaching and detaching states of the main body 200 and the toilet 110 can be detected.

The attachment / detachment sensor 244 is configured by a reed switch, for example.

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

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

As shown in FIG. 20, in a state where the main body 200 is mounted on the toilet 110, the magnet 243 of the main body fixing plate 240 and the attachment / detachment sensor 244 of the rear main body case 201 are arranged in a close and opposite positional relationship. . At this time, the reed switch as the attachment / detachment sensor 244 is turned on by the magnetic force of the magnet 243. Thereby, it can be detected 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 attachment sensor 244, and the reed switch is turned off. Thereby, the attachment / detachment sensor 244 can be used to detect whether the body 200 and the toilet 110 are in a removed state.

In the sanitary washing device according to this embodiment, when the attachment / detachment sensor 244 detects that the body 200 is removed from the toilet 110, the control unit 130 controls not to perform the discharge operation of the spray nozzle 550. Therefore, in a state where the main body 200 has been removed from the toilet 110, even if the user presses a button such as the manual foam coating switch 433 or the manual splash suppression switch 434 of the remote control body 401, the control unit 130 will not execute The discharge nozzle 550 performs a discharge operation. This can prevent undesirable situations such as accidental spraying of washing water or washing foam on the floor or people.

On the other hand, even when the attachment / detachment sensor 244 detects that the body 200 has been removed from the toilet 110, the control unit 130 controls the discharge operation of the hip washing nozzle 831 and the vaginal washing nozzle 832 not to be prohibited. This is because if the sensor 244 fails, the control unit 130 may mistakenly recognize that the main body 200 is removed from the toilet 110. Then, the control unit 130 controls the hip washing and the genital washing, which are basic functions of the sanitary washing device, to be executable. This can suppress a reduction in convenience for the user.

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

Hereinafter, referring to FIG. 21, the operation and control of each part when the rotating foam is dispersed in the sanitary washing device according to this embodiment will be described.

FIG. 21 is a timing chart when the rotating foam is dispersed in the sanitary washing device.

As shown in FIG. 21, at time point N1, the user presses the manual foam coating switch 433 of the remote control body 401. As a result, the control unit 130 reverses the lotion pump 534 at time point N2, for example, 2 seconds, and then forwards the lotion pump 534 at time point N3. 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, lotion, water, and air can be supplied into the foam tank 532, and a cleansing foam can be produced.

The generated washing foam is spread from the discharge opening 550u of the spray nozzle 550 toward the inner surface of the toilet. As a result, adhesion of dirt to the inner surface of the toilet can be suppressed, and dirt can be easily removed.

At this time, the discharge port 550u of the spray nozzle 550 is rotationally driven by a spray nozzle driving unit 550a, which is, for example, a stepping motor. Specifically, the foaming is performed from the discharge port 550u while moving from the stop position (20 ° in FIG. 11) at the time point N3 in FIG. 21 to the extreme position (340 ° in FIG. 11) at the time point N6. After that, the foam is spread while returning from the extreme position at the time point N6 to the stop position at the time point N9.

At the time point N11, the control unit 130 automatically stops the operations of the water pump 516 and the air pump 535 by, for example, timer control. With this, the spinning foam spreading is automatically ended.

At this time, 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 rotating foam dispersion is performed. On the other hand, during the period from time point N3 to time point N4, the time point from time point N6 to time point N7, and the time period from time point N9 to time point N10, the control unit 130 intermittently operates the lotion pump 534 to forward rotation stop.

Furthermore, the intermittent operation described above is based on the results obtained experimentally, and it is possible to mix the lotion, water, and air efficiently and more stably to generate a cleansing foam in the rotating foam dispersion. The intermittent operation of the lotion pump 534 can stably generate a cleaning foam. As a result, unnecessary use of the lotion can be prevented, and labor for replenishing the lotion can be reduced.

Furthermore, in the sanitary washing apparatus of this embodiment, the intermittent operation of the lotion pump 534 is set to operate for 2 seconds in a cycle of 6 seconds, for example.

In addition, in the timing chart shown in FIG. 21, in order to show the case where it is executed as needed, the operation of the heat exchanger 700 is depicted by a dotted line. The reason is that there is a concern that when the temperature of the water supplied from the water pump 516 to the foam tank 532 is lower than 20 ° C. during the rotating foam dispersion, the cleaning foam cannot be stably generated. Here, when the water temperature is low, the heating control is performed by the heat exchanger 700 to heat the washing water to, for example, about 20 ° C. It is shown that the heated washing water is supplied to the foam tank 532 and operated. Thereby, it is possible to prevent the foaming property from being lowered, to generate a good washing foam, and to supply it to the foam tank 532.

In the timing chart shown in FIG. 21, the lotion pump 534 is reversed from the time point N2 to the time point N3 before the time point N3 at which the foam spreading starts. The reason is that in this embodiment, a tube pump is used for the lotion pump 534. The tube pump sends out the lotion liquid and the like in the tube by the flattening action of the roller. Therefore, the lotion liquid is caused to flow backward from the outlet side of the tube by the reverse operation in the previous direction, and the flattened portion is returned to a cylindrical shape. Then, 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 dispersion nozzle 550.

Also, as shown in the timing chart of FIG. 21, from time point N11 to time point N14, the control unit 130 performs an operation of returning the dispersion nozzle driving unit 550a from the stopped position to the original position. Specifically, the spray nozzle driving unit 550a is driven until it comes into contact with the origin position. At this time, the scattering nozzle driving unit 550a presses the rotation detection micro-switch arranged at the origin position. Thereby, the control part 130 recognizes the origin position of the dispersion nozzle drive part 550a comprised by a stepping motor. After that, the control unit 130 drives the spray nozzle driving unit 550a to return to the stop position. The reason is that the stepping motor may slip due to, for example, an increase in some rotational loads. Therefore, it is impossible to complete the rotation driving in accordance with the number of driving steps, and a deviation occurs in the number of driving steps and the amount of rotation. Then, as described above, the reset operation of the origin position by the dispersion nozzle driving unit 550a is performed. Thereby, the stop position which is the start position of the rotating foam spreading of the spreading nozzle driving part 550a can be reset to a correct position, and driving can be started. As a result, the rotation angle of the spray nozzle 550 can be specified with high accuracy using the origin position of the spray nozzle driving unit 550a as a reference, so that the rotating foam spray can be performed at a stable position.

In addition, for some reason, for example, there is a case where a lotion is fixed around the discharge port 550u of the spray nozzle 550, and the spray nozzle driving portion 550a cannot be rotationally driven. In this case, the presence or absence of the on / off of the rotation detection microswitch that was pressed due to the resetting operation of the origin position by the dispersing nozzle driving section 550a can easily detect the malfunction of the dispersing nozzle driving section 550a.

In addition, when the rotation foam is spread, if the ON signal is not input from the rotation detection micro-switch, the washing lamp 223a (refer to FIG. 4) arranged in the operation section 210 is executed in a lighting display mode described below. To notify users of a bad condition. Thereby, the user can urge the user to perform the operation of the washing switch 223, and the washing operation can be performed.

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

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

With respect to the rotation foam spreading time set as described above, when, for example, the time delay until the rotation detection micro switch is pressed is, for example, approximately 10% or more late, the washing lamp 223a is caused to repeat "flashing" and "flashing" 1 Lights up in a blinking action. Thereby, the user can be urged to press the washing switch 223 and execute a washing operation.

During the washing operation, the foam generating unit 560 and the spray nozzle 550 are used to flow the washing water heated to about 40 ° C by the heat exchanger 700, and the washing is performed, for example, for about 3 minutes. The washing operation is performed so that the foam generating part 560, the spray nozzle 550, and the like can be washed with heated washing water. As a result, it is possible to prevent the lotion from sticking or blocking the foam generating portion 560, the spray nozzle 550, and the like, and to perform stable rotating foam spread.

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

As described above, when the washing lamp 223a is turned on and displayed, it is possible to urge the user to respond to the processing based on the detection of the malfunction of the dispersion nozzle driving unit 550a.

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

Specifically, at time points N2 to N3, the fluid regulating valve 517 is closed and the on-off valve 530a is opened to switch the supply destination of the washing water to the foam generating unit 560. On the other hand, at 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 addition, although the on-off valve 530a is described as an example in the above, it is not limited to this. For example, a configuration may be adopted in which the flow path is switched by a flow path switching valve such as a three-way valve arranged at a branched portion of the branched flow path 530 from the washing water supply flow path 690.

As described above, the operation and control of each part when the rotating 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 apparatus will be described with reference to FIG. 22.

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

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

Next, the control unit 130 activates the air pump 535 for about one minute from the time points N8 to N10. Thereby, the air pump 535 can be used to send air together with the washing water heated to about 40 ° C into the foam tank 532, and the washing and washing can be performed.

That is, in the washing operation of washing and washing, first, only the washing water is sent to the foam tank 532. Then, the air pump 535 is actuated from the way of feeding water to add air to the foam tank 532 and perform washing. In this way, 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 spray nozzle 550 into the toilet by washing water. After that, the force of the air bubbles (air) formed by the air pump 535 is added to the foam tank 532 and supplied. At this time, the air bubbles act to wash even a small amount of the residual amount of the lotion component. As a result, effective washing can be performed in a short time.

Next, when the above-mentioned washing for about 3 minutes is completed, at the time points N10 to N14, the control unit 130 reverses the lotion pump 534 and rotates forward. Thereby, the lotion pump 534 is set to the standby operation state, so that the next rotation foam spreading or fixed foam spreading can be started normally. The control unit 130 automatically ends the washing operation by timer control, for example.

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

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

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

As shown in FIG. 23, at time point N1, when the user presses the manual splash suppression switch 434 of the remote control body 401, the control unit 130 sets a fixed foam spreading instruction issuing mode (foam coating mode). Thereby, at the time point N2, the control unit 130 reverses the lotion pump 534 for 2 seconds, and then causes the lotion pump 534 to perform a forward rotation operation at the time point N3. In addition, at time point N3, the control unit 130 starts the operation of the water pump 516 and the air pump 535. Thereby, a lotion, water, and air can be supplied to the foam tank 532, and a washing foam can be produced.

The generated washing foam is spread from the discharge opening 550u of the spray nozzle 550 toward the inner surface of the toilet. At this time, by spreading the fixed foam of the cleansing foam on the inner surface of the toilet, the foam can be accumulated on the water surface of the toilet to a foam height of about 10 mm (see FIG. 25) and covered. In addition, the buffering effect of the washing foam suppresses, for example, the splash of urine when a man urinates.

In addition, the timing chart when the fixed foam is dispersed in FIG. 23 and the timing chart when the rotary foam is dispersed in FIG. 21 are different in the operation of the discharge outlet 550u of the dispersion nozzle 550.

That is, when the rotating foam dispersion shown in FIG. 21 is performed, the outlet 550u of the dispersion nozzle 550 can be rotationally driven by the dispersion nozzle driving part 550a. On the other hand, when the fixed foam spreading shown in FIG. 23 is performed, it is different in that the spreading nozzle driving section 550a does not rotationally drive the discharge outlet 550u of the spreading nozzle 550, but comes in a fixed state. Spread cleansing foam.

A 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, although the origin position, stop position, and extreme position of the scattered nozzle driving unit 550a shown in the timing charts of FIGS. 21 to 23 are described using the angular positions shown below as examples, they are not Limited to this.

That is, although the case where the origin position is the 0 ° (right behind) position shown in FIG. 11, and the case where the stop position is the 20 ° (clockwise) position shown in FIG. 11, the limit position is as shown in the figure. The case of the position of 340 ° (clockwise) shown in 11 is described as an example, but it is not limited to this. For example, a position where the origin position is 5 ° (clockwise from the rear) may be used. The stop position may be a position of 60 ° (clockwise from the rear). The limit position may be a position of 300 ° (clockwise).

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

First, when the fixed foam distribution instruction issuing mode is set, the control unit 130 stops the direction of the discharge port 550u at a stop position of approximately 60 ° clockwise from the rear with the spray nozzle driving unit 550a. Perform fixed foam spreading immediately.

At this time, the control unit 130 drives the dispersing nozzle driving unit 550a, and sets the direction of the discharge port 550u to a stand-by position at about 60 ° which is a stop position in advance. Furthermore, when the fixed foam spreading is instructed in the standby state, the control unit 130 immediately spit out the cleansing foam toward the inner surface of the toilet without moving the spreading 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 male urination begins.

In this case, if the direction of the stop position of the discharge port 550u is set to the above-mentioned position of 50 ° to 70 ° (about 60 °), the following effects are particularly obtained. That is, if the cleaning foam is discharged at the stop position, the cleaning foam will be shot on the inclined surface of the inner surface of the toilet. The cleansing foam sprayed on the inclined surface flows down toward the water surface adjacent to the discharge port 115 in a manner of rotating on the inclined surface of the inner surface of the toilet. Thereby, it is possible to form a foamed film of cleansing foam on the entire water surface in a short time.

Furthermore, in this embodiment, although the configuration for performing the rotating foam spreading shown in FIG. 21 when the manual foam coating switch 433 of the remote control body 401 is pressed is described as an example, it is not limited to this. It may also be set to automatically perform rotating foam spreading, for example, after defecation (that is, after toilet use). In addition, it may also be set to perform the rotating foam spreading automatically every fixed period of time. Thereby, dirt is less likely to adhere to the inner surface of the toilet, and dirt can be more easily removed.

In addition, by rotating the foam dispersion in an automatic manner every fixed period of time, it is possible to effectively suppress the formation of dirt near the waterline in the toilet, especially the formation of ring-shaped stains.

At this time, when the rotating foam dispersion is performed in an automatic operation after defecation, in the sanitary washing device of this embodiment, the seating sensor 330 is set to detect that the user stands up from the toilet seat 300 And, for example, after about 60 seconds, the spinning foam spreading is performed in 15 seconds.

On the other hand, it is set such that, when the male who is not seated in the toilet seat is urinating, when the toilet seat opening sensor 331 detects that the toilet seat 300 is closed, for example, after about 60 seconds, it takes 15 seconds. Time to perform spinning bubble spread.

Furthermore, in the above description, although the example is described with the sensor detecting and performing the rotating foam dispersion after about 60 seconds, it is not limited to this. The switch of the remote control body 401 can be arbitrarily changed to, for example, about 10 seconds later, 25 seconds later, or the like. In this way, the time before the rotation of the foam spreading can be adjusted to an arbitrary time in accordance with the user's usage mode.

In the above description, the time for performing the spinning foam dispersion is described with an example of about 15 seconds, but it is not limited to this. The switch of the remote control body 401 can be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of foam to be distributed can be arbitrarily adjusted in accordance with the size of the toilet and the like.

In the present embodiment, the configuration of performing the fixed foam spreading shown in FIG. 23 when the manual splash suppression switch 434 of the remote control body 401 is pressed is described as an example, but it is not limited to this. It may be set to automatically perform fixed foam spreading, for example, when the toilet seat is already opened. Thereby, when the toilet seat 300 is opened when the male urinates, the fixed foam spreading can be automatically performed. As a result, it is possible to effectively suppress the splash of urine when men urinate.

Furthermore, when the fixed seat is set to perform automatic foam spreading when the toilet seat is already opened, when the toilet seat 300 is opened, the fixed foam distribution is performed for about 15 seconds, for example.

It should be noted that although the above description has been made taking about 15 seconds as an example of the time for performing the fixed foam distribution, the present invention is not limited to this. The switch of the remote control body 401 can be arbitrarily changed to, for example, 10 seconds, 25 seconds, or the like. Thereby, the amount of foam to be distributed can be arbitrarily adjusted in accordance with the size of the toilet and the like.

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

Hereinafter, a configuration of an automatic operation for selectively setting the fixed foam spreading or the rotating foam spreading in the sanitary washing device will be described with reference to FIG. 24.

FIG. 24 is a diagram illustrating selection settings of automatic operation during fixed foaming or rotating foaming in the sanitary washing device.

In addition, for the automatic operation during fixed foam spreading or rotating foam spreading, the automatic selection setting switch 236 of the operation unit 210 can be pressed every time to select a preferred setting.

Specifically, as shown in the left diagram of FIG. 24, an operation switch 220 is arranged on the operation unit 210 and an automatic selection setting switch 236 is arranged. Next to the automatic selection setting switch 236 are disposed an automatic rotation dispersing lamp 236a after use, an automatic rotation dispersing lamp 236b at a fixed period of time, and an automatic fixing foam dispersing display lamp 236c when the toilet seat is opened. In addition, each time the automatic selection setting switch 236 is pressed, each lamp is displayed in the order indicated by the arrow in the right figure of FIG. 24. Thereby, three kinds of automatic operations can be set in any combination according to the user's preference.

Specifically, H0 indicates that all of the automatic rotation dispersing lamp 236a after use, the automatic rotation dispersing lamp 236b at a fixed period of time, and the automatic fixing foam dispersing display lamp 236c when the toilet seat is turned on are all off. In other words, H0 indicates a state in which all three types of automatic operation are “off”.

When the automatic selection setting switch 236 is pressed once from this state of H0, it will be in the H1 state in which only the automatic rotation dispersing lamp 236a lights up after use. That is, each time the setting switch 236 is automatically selected, the settings are switched to the states of H2, H3, ..., H6. In addition, when the automatic selection setting switch 236 is pressed once from the state of H6, the three states of H7 in which all automatic operations are "on" are set. Furthermore, 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 state of H2, H4, H6, and H7 in which the setting of the rotating foam distribution is performed automatically at regular intervals as shown in FIG. 24, the rotating foam illustrated in the timing chart of FIG. 21 may be distributed. It is performed in an automatic manner every, for example, about 3 hours. Thereby, it is possible to suppress the formation of dirt near the waterline in the toilet, particularly the formation of ring-shaped stains.

In addition, the above-mentioned settings performed every about 3 hours can be changed to, for example, every about 6 hours, every 12 hours, or about 24 hours by the switch of the remote control body 401. Arbitrary settings. Thereby, the number of automatic operations and the like must be reduced during long absences, and can be arbitrarily adjusted according to the situation of the user.

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

Hereinafter, the sanitary washing apparatus in Embodiment 2 is demonstrated using FIG.27 and FIG.28.

FIG. 27 is a perspective view of a sanitary washing device in Embodiment 2. FIG. FIG. 28 is a schematic view showing a cross section of a main part of the sanitary washing device in the embodiment.

As shown in FIGS. 27 and 28, the sanitary washing device according to this embodiment is a so-called toilet-integrated sanitary washing device 1000 in which a toilet 110 and a body 200 are integrally formed.

In addition, in FIG. 27, in order to explain the structure inside the toilet 110, the toilet seat 300 and the seating sensor 330 shown in FIG. 1 described in Embodiment 1 are not shown. However, the sanitary washing apparatus 1000 shown in FIG. 27 is similarly provided with a toilet seat and a seating sensor.

That is, the sanitary washing apparatus 1000 of this embodiment is different from the so-called additional type sanitary washing apparatus 100 in which the main body 200 is set on the toilet 110 afterwards as described in the first embodiment. In addition, since the basic structure and function are the same as those of the sanitary washing device 100 according to the first embodiment, the same components are denoted by the same reference numerals, and detailed description is omitted. For example, the sanitary washing apparatus 1000 is similar to the sanitary washing apparatus 100 of Embodiment 1 and has a structure which performs a foam spreading operation.

Specifically, the sanitary washing device 1000 is different from the sanitary washing device 100 of the first embodiment in that the remote control 900 for washing the toilet and the toilet washing flow path 920 including the flush switch 910 are further included. .

The toilet washing flow path 920 connects one end to, for example, an external water supply connection port (see FIG. 6). The other end of the toilet washing flow path 920 is provided with a toilet water spout 940. The toilet water spout 940 may be provided, for example, on the right side of the upper part of the toilet, about 1/3 of a week from the rear, and adjacent to the edge 950 located at the front position.

The toilet flushing flow path 920 is provided with a flush valve 930 in the middle. The flush valve 930 causes the toilet washing flow path 920 to open and close according to the signal of the flush switch 910. At this time, when the flush valve 930 is opened, for example, water supplied from the outside may be discharged from the toilet spout 940 to the vicinity of the edge 950 so as to follow the inner circumference of the toilet 110. Thereby, flushing of a toilet bowl after urination, or flushing of a toilet bowl after defecation is formed.

The sanitary washing apparatus 1000 is configured as described above.

In the following, the operations and functions of the sanitary washing apparatus 1000 that are different from those of the sanitary washing apparatus 100 of the first embodiment will be described.

First, for example, after the toilet is used, the user presses the flush switch 910. At this time, the ON signal of the flush switch 910 is input to the control unit 130 in the main body 200 through a form such as infrared rays. The control unit 130 opens the flush valve 930 of the toilet washing flow path 920 according to the inputted open signal. Thereby, the water is discharged along the inner circumference of the toilet 110 from the toilet water outlet 940 of the toilet washing flow path 920 near the edge 950 of the toilet upper part. The spouted water flows around the lower edge of the toilet while flowing around the edge 950 of the toilet, and is discharged from the toilet drain 960.

At this time, when the control unit 130 of the sanitary washing device 1000 cleans the toilet that discharges water from the toilet water outlet 940, it will direct the water outlet 550u of the spray nozzle 550 toward, for example, the water discharged near the toilet water outlet 940 to spit out. Wash the foam.

That is, the outlet 550u of the spray nozzle 550 directs the washing foam toward the water near the toilet bowl water outlet 940 which is discharged from the toilet bowl water outlet 940. Thereby, even if the foam spreading by the spraying nozzle 550 cannot reach the position closer to the edge 950 of the upper part of the toilet even with the foam spreading, it can be strongly washed with the water mixed with the foam.

Specifically, the water discharged from the toilet spout 940 will gradually flow to the lower part of the toilet while swirling along the inner circumference of the adjacent portion of the upper edge 950 of the toilet.

At this time, the control unit 130 spreads the washing foam from the discharge port 550u of the spray nozzle 550 toward the water near the toilet water spout 940. Thereby, the washing foam is mixed with the water discharged from the toilet spout 940. In addition, the water mixed with the washing foam will gradually flow to the lower part of the toilet while spiraling along the inner circumference of the adjacent part of the edge 950 of the upper part of the toilet in the toilet 110. Therefore, from the vicinity of the edge 950 of the upper part of the toilet to the lower part of the toilet where the toilet drain 960 is located, the water mixed with the washing foam is widely delivered. Thereby, the inner surface of a toilet can be cleaned more reliably with the water mixed with a washing foam, without uneven washing. As a result, generation of dirt and the like can be effectively suppressed.

In the second embodiment described above, the configuration is described by taking, as an example, a configuration in which water is discharged from the spray nozzle 550 toward the vicinity of the toilet spout 940 when the toilet is washed, but the invention is not limited to this. For example, not only the vicinity of the toilet spout 940, but also the inner surface of the toilet may be configured to spit out water from the toilet spout 940 while spreading a washing foam.

In addition, in the second embodiment described above, although the point in time when the cleaning foam is spread from the spray nozzle 550 toward the water near the toilet spout 940 is not particularly mentioned, it may be performed at the following timing.

For example, the time when the washing foam is sprayed from the spray nozzle 550 and the time when the water is discharged from the toilet spout 940 may be used at the same time. Alternatively, after the water starts to be discharged from the toilet spout 940, a time lag is set to spread the washing foam from the spray nozzle 550. At any point in time, the same effect can be obtained by vigorously rinsing the water mixed with the cleansing foam in the toilet in a widely delivered manner.

In addition, when the control unit 130 inputs the ON signal of the flush switch 910, the control unit 130 may first spread the washing foam from the spray nozzle 550 on the whole or a part of the inner surface of the toilet. After that, the control unit 130 opens the flush valve 930 to allow water to be discharged from the toilet spout 940. At this time, the control unit 130 may further continuously or intermittently spread the washing foam from the spray nozzle 550 toward the inner surface of the toilet 110 or the water near the toilet water spout 940 to clean the toilet 110. Thereby, a more efficient washing effect can be obtained.

In the second embodiment, although not specifically described, the control unit 130 may perform the following operations after defecation and after washing the toilet.

Specifically, the control unit 130 closes the flush valve 930 after defecation and after washing the toilet. In this state, the control unit 130 performs a rotating foam spreading operation in the same manner as in the first embodiment. This rotating foam spreading operation is to rotate and drive the direction of the outlet 550u of the spray nozzle 550 and spread the cleansing foam to the toilet. Inside. Thereby, after the toilet is cleaned, a foam film is formed in advance on the inner surface of the toilet from the front to the rear. As a result, adhesion of dirt can be effectively suppressed.

In the second embodiment described above, the configuration of performing toilet cleaning after the user operates the flush switch 910 of the remote controller 900 for toilet cleaning is described as an example, but the invention is not limited to this. It can also be set to, for example, the following configuration: When the seating sensor (not shown) detects that the user has left the seat (not shown), that is, after a predetermined time, for example, 30 seconds, it is executed automatically. Wash the toilet. Thereby, it is possible to reliably prevent the user from forgetting to wash the toilet. It is also possible to adopt a configuration in which the remote controller 900 for toilet cleaning is not separately provided.

Specifically, as described in the first embodiment, the sanitary washing apparatus 1000 according to this embodiment includes a seating sensor (see FIG. 1) that can detect the presence or absence of a user sitting in a toilet seat (see FIG. 1). Therefore, as long as the seat sensor is used and the user detects that the user has left the seat, the toilet washing may be performed in an automatic manner.

Moreover, in the above description, although the toilet washing was started after a predetermined time, for example, about 30 seconds, the toilet washing may be started at a time point after the user's departure is detected. , For example, after about 20 seconds or after 60 seconds. That is, 30 seconds of the predetermined time is merely a mere illustration, and is not a particularly limited time.

With the above configuration, even if the user forgets to operate the flush switch 910 of the remote controller 900 for toilet cleaning after defecation, the toilet cleaning is still performed automatically. Therefore, the toilet 110 can always be maintained in a clean state.

Furthermore, it is preferable that the control unit 130 does not prevent the user from leaving the seat when the user has operated the flush switch 910 to instruct the toilet to wash before the predetermined time elapses. Wash the toilet in an automatic manner. Thereby, repeated washing of the toilet can be avoided. Therefore, it is possible to prevent wasteful use of the lotion and the like used for the foam dispersion.

Furthermore, in the second embodiment described above, although the configuration in which the flush switch 910 is separately provided on the remote control 900 for toilet cleaning separately from the remote control 400 is described as an example, the present invention is not limited to this.
