  About the sanitary washing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user enters the toilet space, the human body detecting means 91 detects the entrance of the human body, the user opens the toilet lid 14, and further, the user is a boy and raises the toilet seat 13 so as to make a small use. Then, the toilet seat 13 is opened, the opening of the toilet seat 13 is detected by the rotation detection means, the target display means 70 is turned on, and the urination target is displayed on the stored water surface. The term “reserved water surface” refers to the water surface of a part of the toilet that always stores water for the purpose of deodorization.

  When the toilet is finished and the toilet seat 13 is turned over on the toilet 10, the toilet seat 13 is closed, the rotation detecting means detects it, and the target display means 70 is turned off. Further, even when the user leaves the toilet space without closing the toilet seat 13 after the end of the toilet, the human body detecting means 91 detects the withdrawal of the human body and turns off the target display means 70 after a predetermined time.

  On the other hand, when the toilet seat 13 is used while being seated on the toilet seat 13 in a state where the toilet seat 13 is placed on the toilet 10 and closed, the target display means 70 is not lit. In this state, the nozzle device 15 is in a storage state where no nozzle is used, the nozzle body 22 is located at the rearmost part of the nozzle guide 19, and the nozzle cover 23 is also located at the rearmost part of the sliding range. The provided positioning projection 51 is in contact with a stopper 53 provided on the side of the nozzle guide 19, and both the nozzle body 22 and the nozzle cover 23 are disposed at the most retracted position. At this time, the connecting projection 50a of the connecting piece 50 is in a state of being fitted into the rear recessed portion 48b of the connecting receiving portion 48 as shown in FIG. 21, and the sliding restricting projection 49b is shown in FIG. It arrange | positions in the rear-end part vicinity of the groove | channel 51a.

  When the user finishes the stool and performs the washing operation with the operation means, the control means starts the control, and the rotation of the drive motor 44 is transmitted to the pinion gear 46 so that the rack 34 meshes with the pinion gear 46. However, since the nozzle body 22 cannot move backward any more, the position in the front-rear direction does not change. With this position as the origin, the subsequent positions of the nozzle body 22 can be controlled while estimating the amount of movement of the nozzle body 22 by detecting the rotation speed of the drive motor 44 with the rotation speed detection sensor 47. .

  Next, the drive motor 44 is reversely rotated to move the nozzle body 22 forward. At this time, the nozzle cover 23 moves forward in a state of being pulled and integrated with the nozzle body 22 by maintaining the state in which the connection protrusion 50a of the connection piece 50 is fitted in the rear recessed portion 48b of the connection receiving portion 48.

  When the user's operation is a hip cleaning operation, as shown in FIGS. 5, 15, and 18, the nozzle body 22 and the nozzle cover 23 moved forward follow the control sequence set in advance. When the rotational speed of the drive motor 44 from the origin state reaches a set value, the drive motor 44 stops. At this time, the positioning projection 51 provided on the nozzle cover 23 is in a state of being stopped just before contacting the front stopper 52 provided on the side of the nozzle guide 19, and this position becomes the standard position for butt washing.

  In this state, the control means controls the washing water supply means, and the butt washing is started by passing water through the butt washing flow path 28. The wash water that has flowed into the buttocks cleaning flow path 28 passes through the curved portion 28b from the straight portion and is ejected from the buttocks washing outlet 31. Generally, if the washing water is ejected through the curved portion 28b, A turbulent velocity gradient is generated at the curved portion 28b, the ejection direction from the buttocks washing ejection port 31 becomes unstable, and it becomes impossible to eject appropriately toward the local area.

  In the curved portion 28b, the flow velocity on the outer peripheral side is increased, and the flow velocity on the inner peripheral side is decreased. At this time, a turbulent flow is generated because the flow stagnates on the inner wall of the buttocks cleaning channel 28.

  In order to eliminate this phenomenon, in the present embodiment, by providing a rectifying wall 28c on the curved portion 28b, the flow on the outer peripheral side and the flow on the inner peripheral side are separated to generate a rectifying effect and reduce turbulent flow. Can do. As a result of verifying the installation position of the rectifying wall 28c by experiment, it has been found that the rectifying effect is maximized by providing it slightly inward from the center of the flow path of the curved portion 28b, and in this embodiment, it is installed at that position. .

  The washing water that has passed through the curved portion 28b is ejected from the ejection port 31 toward the local part of the user seated. The ejection port 31 of the present embodiment has a two-stage shape having a large hole portion 31a and a small small hole portion 31b. By changing the opening area and changing the flow velocity to generate turbulent flow, the washing water becomes an intermittent flow and hits the local area, and the user feels stronger than the load actually applied to the local area.

  The switching of the water flow path and the adjustment of the flow rate are performed by a flow rate adjusting valve provided in the washing water supply means. At this time, the upper part of the buttocks washing outlet 31 and the bidet washing outlet 32 is covered with the nozzle cover 23, and the sewage generated by the buttocks washing is not directly applied. The cleaning outlet 32 is kept clean.

  In addition, when the sealing performance of the flow rate control valve is insufficient, the flow rate switching between the buttocks cleaning channel 28 and the bidet cleaning channel 29 is not performed completely, and a minute amount of water is discharged from the bidet cleaning jet port 29 even during the buttocks cleaning. However, since the upper part of the bidet washing outlet 29 is covered with the nozzle cover 23, there is no possibility that the water is jetted outside the nozzle.

  When the drive motor 44 is driven to rotate forward and reverse alternately while the buttocks are being washed, the nozzle body 22 and the nozzle cover 23 are swung back and forth with respect to the standard position, and the washing water Can wash a wider area of the human body simultaneously.

  When the butt cleaning is stopped, the drive motor 44 rotates in the reverse direction, the nozzle body 22 and the nozzle cover 23 move rearward, and return to the original storage state.

  Next, when bidet cleaning is selected, after confirming the origin position of the nozzle body 22 in the same manner as the butt cleaning, the drive motor 44 rotates to move forward, and the nozzle body 22 and the nozzle cover 23 move forward. This is the same as in the case of buttocks cleaning, but in the case of bidet cleaning, the nozzle body 22 is moved further forward beyond the buttocks cleaning position.

  At this time, as shown in FIG. 19, the positioning projection 51 provided on the nozzle cover 23 abuts on the front stopper 52 provided on the side of the nozzle guide 19, and the nozzle cover 23 cannot move any further. When the nozzle body 22 is further moved forward, the connection protrusion 50a of the connection piece 50 is detached from the rear recess 48b. In order to enable such an operation, it is a condition that the driving torque of the driving motor 44 that moves the nozzle in the front-rear direction is larger than the load value required to remove the connecting protrusion 50a.

  The nozzle main body 22 and the nozzle cover 23 are separated from each other by the disconnection of the connecting protrusion 50a from the rear concave portion 48b, and only the nozzle main body 22 is forward of the nozzle cover 23 whose movement is restricted by the front stopper 52. The bidet nozzle portion 26 of the nozzle body 22 starts to advance from the bidet nozzle inlet / outlet port 35 provided on the tip surface of the nozzle cover 23.

  When the nozzle body 22 is further moved forward, the connection protrusion 50a is fitted into the front recessed portion 48a. When the connecting protrusion 50a is completely fitted into the front recessed portion 48a, the bidet nozzle portion 26 of the nozzle body 22 is completely advanced from the bidet nozzle entrance 35 as shown in FIG. At this time, position control based on the number of rotations of the drive motor 44 is performed in advance by a control sequence so that the forward movement of the nozzle body 22 is completed. At this time, if the nozzle body 22 is to be moved further forward due to a malfunction of the drive motor 44, the slide restricting projection 49b abuts against the front end of the slide restricting groove 51a to restrict further forward movement. Thus, the connecting protrusion 50a does not jump out of the front recessed portion 48a.

  The drive motor 44 is moved backward to a standard position for bidet cleaning when the drive motor 44 is slightly rotated in the reverse direction with the connection protrusion 50a fitted in the front recess 48a in this manner. Stop. This state is the standard position for bidet cleaning shown in FIG.

  When the nozzle body 22 reaches the standard position for bidet washing, the control means controls the washing water supply means to start water flow through the bidet washing flow path 29, thereby starting bidet washing. The switching of the water flow path and the adjustment of the flow rate are performed by a flow rate adjustment valve of the washing water supply means. At this time, the upper part of the buttocks washing spout 31 is covered with the nozzle cover 23, and the sewage generated by the bidet washing does not directly reach the buttocks washing spout 31. To be kept. In addition, when the sealing performance of the flow rate control valve is insufficient, the flow rate switching between the buttocks cleaning flow path 28 and the bidet cleaning flow path 29 is not performed completely, and a minute amount of water is discharged from the buttocks cleaning jet 31 even during bidet cleaning. However, since the upper part of the buttocks cleaning jet 31 is covered with the nozzle cover 23, there is no possibility that the water is jetted outside the nozzle.

  When the drive motor 44 is driven so as to alternately repeat forward rotation and reverse rotation while performing bidet cleaning, the nozzle body 22 and the nozzle cover 23 are swung back and forth with respect to the standard position, and the cleaning water A wider area of the human body can be cleaned simultaneously.

When the bidet cleaning is stopped, the drive motor 44 rotates in the reverse direction, and the nozzle body 22 and the nozzle cover 23 start moving backward. In the middle of moving backward for storage, the positioning projection 51 provided on the nozzle cover 23 abuts on the rear stopper 53 provided on the side of the nozzle guide, and the nozzle cover 23 cannot move any further. When the nozzle body 22 is further moved rearward, the connection protrusion 50a of the connection piece 50 is detached from the front recess 48a.
In order to enable such an operation, it is a condition that the driving torque of the driving motor 44 that moves the nozzle body 22 in the front-rear direction is larger than the load value required for releasing the connection protrusion 50a.

  The nozzle main body 22 and the nozzle cover 23 are separated from each other by the disconnection of the connecting protrusion 50a from the front recessed portion 48a, and only the nozzle main body 22 is rearward of the nozzle cover 23 whose movement is restricted by the rear stopper 53. As a result, the bidet nozzle portion 26 of the nozzle body 22 starts to be housed in the bidet nozzle inlet / outlet port 35 provided on the front end surface of the nozzle cover 23. When the nozzle body 22 is further moved rearward, the connection protrusion 50a gets stuck in the rear recess 48b. When the connecting protrusion 50a is completely inserted into the rear recessed portion 48b, the bidet nozzle portion 26 of the nozzle body 22 is completely stored in the bidet nozzle inlet / outlet 35. At this point, the nozzle body 22 contacts the rear end of the nozzle guide 19 and cannot move any further backward. The rotation of the drive motor 44 is stopped by position control based on the number of rotations of the drive motor 44 based on a preset control sequence.

  When the butt cleaning and the bidet cleaning are completed and the nozzle body 22 is stopped at the storage position, the control means starts the nozzle cleaning control. The control means controls the washing water supply means, and the nozzle washing is started by starting water flow through the nozzle washing flow path 30. The switching of the water flow path and the adjustment of the flow rate are performed by a flow rate adjustment valve of the washing water supply means.

  When water passes through the nozzle cleaning flow path 30, cleaning water is ejected from the two nozzle cleaning ejection ports 33 provided at the front end portion of the large diameter portion 25 of the nozzle body 22. The cleaning water sprayed from the external cleaning nozzle 33 b provided on the outer surface is sprayed to the outside of the nozzle cover 23 through the nozzle cleaning opening 37 provided in the nozzle cover 23, and the cleaning enlarged portion of the nozzle guide 19 covering the nozzle cover 23. The outer peripheral wall of the nozzle cover 23 and the buttocks cleaning spout 31 are cleaned with cleaning water that hits the inner wall 40 and rebounds. Also, the washing water ejected from the internal washing outlet 33a provided downward flows to the side portion of the bidet nozzle portion 26 of the nozzle body 22 and cleans the surface of the bidet nozzle portion 26 and the bidet washing ejection port 32.

  At this time, as shown in FIG. 9, the internal cleaning outlet 33 a, the external cleaning outlet 33 b, and the nozzle cleaning opening 37 are set in a direction offset from the diameter direction of the nozzle body 22, so 19 and the nozzle cover 23 are swirled in the circumferential direction, and the contamination of the nozzle body 22 and the nozzle cover 23 can be effectively removed. The washed water that has been washed is discharged from drain ports 39 and 41 provided below the nozzle cover 22 and the nozzle guide 19, and the washed water that has flowed out of the drain groove 39 passes through the outer surface of the lens portion 71 b of the target display means 70. Then, after washing the lens portion 71b of the target display means 70, it flows into the toilet bowl 10.

  As described above, in the present embodiment, a nozzle body including a butt cleaning spout for ejecting cleaning water, a bidet cleaning spout, a nozzle cleaning spout, and a flow path for supplying cleaning water to each spout And a cylindrical nozzle cover that covers the nozzle body and has an ejection opening corresponding to the butt cleaning ejection port, a connecting means for coupling the nozzle body and the nozzle cover, a nozzle guide for housing the nozzle body and the nozzle cover, By providing a drive means for driving the nozzle body to advance and retreat, the nozzle and the flow path are integrated in the nozzle body, and the nozzle cover can be made simple, so the entire nozzle device is small. It can be set as a simple structure.

  In addition, by sliding the nozzle body and the nozzle cover relative to each other, by aligning the corresponding jet outlet and the jet opening, the washing water from the butt washing jet outlet is jetted through the jet opening, When the washing water is jetted, the nozzle body, particularly the vicinity of the bidet washing jet outlet and the buttocks washing jet outlet, is covered with a nozzle cover, so that the nozzle body is not contaminated by washing water that is dirty by washing, and is hygienic.

  In addition, by providing target display means that displays in conjunction with the opening and closing of the toilet seat, it is possible to guide the position of urination during boys' small use, so it is possible to suppress scattering of urine outside the toilet and outside the toilet As a result, the toilet and the toilet space around the toilet can be maintained in a sanitary manner.

  In addition, the nozzle cover has a simple configuration without using an adhesive or a joining member by fixing the nozzle cover body formed of stainless steel and the cover rear end member by resin molding by fitting the fixing projection 23d and the fixing hole. It is securely joined. Moreover, since the nozzle cover is made of stainless steel, dirt is difficult to adhere and the attached dirt can be easily removed by washing.

  In addition, when cleaning the bidet, the cleaning nozzle is ejected with the bidet nozzle projecting from the front end surface of the nozzle cover, so that the cleaning water can be sprayed close to the cleaning target, and a delicate spray configuration is desired. Can be carried out directly from the bidet washing outlet, so that an optimum injection form can be obtained.

  In addition, since the nozzle cover is linked to the nozzle body between the storage position and the buttocks cleaning position via the connecting means, only the nozzle body is driven by the driving means, and both the nozzle body and the nozzle cover are connected together. In addition to sliding, only the nozzle main body can be slid independently to the bidet cleaning position, and two driving objects can be driven to their optimum positions by one driving means. Cost can be reduced.

  In addition, the cleaning water sprayed from the outer cleaning outlet of the nozzle cleaning outlet provided in the nozzle body is jetted to the cleaning enlarged portion of the nozzle guide through the nozzle cleaning opening and reflected by the nozzle guide, and the outer surface of the nozzle cover and the nozzle guide The cleaning water sprayed from the internal cleaning outlet can be reflected by the nozzle cover to mainly clean the outer surface of the bidet nozzle and the inner surface of the nozzle cover, and at the same time the nozzle and nozzle cover are cleaned, the target is displayed. Since the device is also cleaned, the self-cleaning mechanism of the nozzle body, nozzle cover and target display means that are contaminated with sewage and filth in butt cleaning and bidet cleaning is realized with a small and simple configuration, and the hygienic nozzle device Providing and maintaining the projection function of the target display means can be maintained.

  In addition, by providing a rectifying wall in the curved part of the flow path, by suppressing turbulent flow in the flow path, it is possible to stabilize the ejection direction from the buttocks washing ejection port, and appropriately toward the local area Wash water can be spouted out. Moreover, by making the upstream end and the downstream end of the rectifying wall thin and pointed, the flow of washing water can be smoothly divided and mixed again. In particular, since the separated jets are smoothly mixed by making the downstream side thin and sharp, the rectifying effect is increased. Conversely, when the downstream side of the rectifying unit is shaped to leave an edge, vortices are generated by collision when the separated washing water merges, and flow separation at the edge is likely to occur, causing intermittent flow. It becomes.

  In addition, by using a two-stage shape for the butt cleaning spout, a large hole part and a small hole part, the wash water becomes an intermittent flow and hits the spray local part, so it feels stronger than the load actually applied to the local part. A person can obtain a high feeling of cleaning.

  In this embodiment, the nozzle drive means employs a transmission mechanism via a gear including a drive motor, a worm gear, a transmission gear, and a pinion gear. However, the present invention is not limited to this. A mechanism may be used.

  In the present embodiment, the connecting piece of the connecting means is formed of a metal material having elasticity. However, the connecting piece is not limited to this, and may be a resin material having elasticity. The members can be molded integrally and can be manufactured at low cost.

  In this embodiment, the thickness of the rectifying wall is set to 0.5 mm. However, the thickness is not limited to this. A thickness of about 0.5 to 1.0 mm is necessary. On the other hand, in order to suppress the pressure loss of the flow path, it is desirable to form the rectifying wall as thin as possible. Therefore, in this embodiment, the minimum thickness is 0. .5mm was adopted. As a method of forming the rectifying wall thinner, a method of forming the rectifying wall as a separate member with a metal or the like and arranging it on the curved portion of the butt cleaning flow path can be considered.

  Moreover, in this Embodiment, although the thickness of the small hole part was 0.5 mm, it is not restricted to this, By making it the thickness of the range of 0.5-1.5 mm, the intermittent flow of washing water is It has been confirmed that the desired intermittent flow can be obtained by selecting the thickness. Moreover, although the opening area of the large hole portion is about twice that of the small hole portion, it has been confirmed that an intermittent flow can be obtained in the range of 1.5 to 2.5 times in this respect as well. By changing it, an optimal intermittent flow can be obtained.

  In addition to detecting the presence or absence of the user seated on the toilet seat using infrared rays, the seating detection means includes a method for detecting the capacitance of the toilet seat 3 as a method, and a user's toilet seat using ultrasonic waves or the like. 3 may be one that detects seating on the seat 3, or one that detects the pressure on the toilet seat seat.
