  In addition, a seating sensor 17 is provided in the upper part of the front portion of the main body 11. The seating sensor 17 is composed of, for example, an infrared sensor, and detects whether or not a user is seated on the toilet seat 15. A so-called movable cleaning nozzle 18 is provided at the lower part of the front part of the main body 11. In this case, the cleaning nozzle 18 has a cylindrical shape extending linearly along the front-rear direction of the toilet seat apparatus 10 and is provided so as to be reciprocally movable along the front-rear direction of the toilet seat apparatus 10.

  As illustrated in FIG. 2, the cleaning nozzle 18 includes a nozzle body 21, a water supply cylinder 22, a nozzle motor 23, a first water supply cylinder motor 24, a second water supply cylinder motor 25, and the like. The nozzle body 21 forms the body of the cleaning nozzle 18 and has a cylindrical shape extending linearly. A water supply cylinder storage portion 21 a that extends linearly along the axial direction of the nozzle main body 21 is provided at the center of the nozzle main body 21 in the radial direction.

  The tip surface of the nozzle main body 21 is closed. Moreover, the water discharge part 26 is provided in the surrounding surface of the front-end | tip part of the nozzle main-body part 21, and the upper surface which opposes the user's buttocks put on the toilet seat 15 in this case. As illustrated in FIG. 3, the water discharge portion 26 is provided with a plurality of, in this case, nine water discharge ports 26 a to 26 i. The water discharge part 26 is the structure which arranged eight water discharge ports 26b-26i around the center water discharge port 26a. The water discharge ports 26a to 26i communicate with the distal end portion of the water supply cylinder storage portion 21a.

  Further, the water discharge ports 26a to 26i are directed in different directions. In the configuration example illustrated in FIG. 3, the central water outlet 26 a is oriented in a direction orthogonal to the axial direction of the nozzle body 21. That is, when a user existing on the front side of the toilet seat device 10 looks at the tip of the nozzle body 21 from above, the central water outlet 26a is directed upward.

  On the other hand, the other eight water outlets 26b to 26i are oriented as follows. That is, when the user existing on the front side of the toilet seat device 10 sees the tip end portion of the nozzle body 21 from above, the water outlet 26b is oriented in the direction inclined left rearward and upward, and the water outlet 26c is leftward and upward. The water outlet 26d is oriented in the direction inclined leftward and upward. Further, when the user existing on the front side of the toilet seat device 10 sees the tip end portion of the nozzle main body 21 from above, the water outlet 26e is oriented in a direction inclined backward and upward, and the water outlet 26f is inclined forward and upward. Oriented in the direction. Further, when the user existing on the front side of the toilet seat device 10 sees the tip end portion of the nozzle body 21 from above, the water outlet 26g is directed to the right rearward and upwardly inclined direction, and the water outlet 26h is rightward and upward. The water outlet 26i is oriented in a direction inclined to the right front and upward.

  As illustrated in FIG. 2, the water supply cylinder 22 has a cylindrical shape smaller than the water supply cylinder storage portion 21a, and is stored in the water supply cylinder storage portion 21a so as to be capable of reciprocating along the axial direction. Yes. The front end surface of the water supply cylinder 22 is closed. Further, in this case, one water supply port 27 is provided on the peripheral surface of the front end portion of the water supply cylinder 22, in this case, the upper surface facing the user's buttocks placed on the toilet seat 15.

  The nozzle motor 23 is an example of nozzle moving means, and rotates the wheel 23a in the directions of arrows a1 and a2 to move the nozzle body 21 in the axial direction of the cleaning nozzle 18, in other words, the front-rear direction of the toilet seat device 10. Reciprocate along. As a result, the entire cleaning nozzle 18 reciprocates in the directions of the arrows A1 and A2 along the front-rear direction of the toilet seat device 10.

  The first water supply cylinder motor 24 rotates the wheel 24a in the directions of the arrow b1 and the arrow b2 to move the water supply cylinder 22 in the axial direction of the cleaning nozzle 18, in other words, the toilet seat device 10 in the nozzle body 21. Move back and forth along the front-rear direction. As a result, the water supply cylinder 22 reciprocates in the arrow B1 direction and the arrow B2 direction along the front-rear direction of the toilet seat device 10 inside the nozzle body 21.

  The second water supply cylinder motor 25 rotates the water supply cylinder 22 around the central axis of the cleaning nozzle 18 inside the nozzle body 21 by rotating the wheel 25a in the directions of the arrows c1 and c2. As a result, as illustrated in FIG. 4, the water supply cylinder 22 rotates in the direction of the arrow C <b> 1 and the direction of the arrow C <b> 2 around the central axis of the cleaning nozzle 18 inside the nozzle body 21.

  As illustrated in FIG. 2, a movement restricting portion 28 having a diameter larger than that of the water supply cylinder storage portion 21 a is provided in the base end portion of the nozzle body portion 21, that is, the inside opposite to the tip portion. A distal end side touch sensor 29 is provided on the distal end side of the movement restricting portion 28, and a proximal end side touch sensor 30 is provided on the proximal end side of the movement restricting portion 28. On the other hand, an annular movement restricting component 31 is fixed to the proximal end portion of the water supply cylinder 22. The movement restricting component 31 is housed in the movement restricting portion 28 so as to be movable.

  Next, a configuration example of the control system of the toilet seat apparatus 10 will be described. The control device 41 illustrated in FIG. 5 is configured mainly with a microcomputer, for example, and controls the overall operation of the toilet seat device 10. The toilet seat device 10 is connected to an operation input unit 14, a seating sensor 17, a nozzle motor 23, a first water supply cylinder motor 24, a second water supply cylinder motor 25, a distal end side touch sensor 29, and a proximal end side touch sensor 30. . Further, a water supply pump 42 for supplying water to the water supply cylinder 22, a warm water heater 43 for warming water supplied to the water supply cylinder 22, a toilet seat heater 44 for warming the toilet seat 15, and the like are connected to the control device 41.

  Moreover, the control apparatus 41 implement | achieves the water discharge area | region change process part 51 virtually by software by running a control program. In addition, the control apparatus 41 may comprise the water discharge area | region change process part 51 by hardware, and may be comprised by the combination of software and hardware.

  The water discharge area change processing unit 51 is an example of a water discharge area change means, and the water supply cylinder 22 is moved in the water supply cylinder storage part 21a of the cleaning nozzle 18 in the axial direction and the circumferential direction in accordance with an operation input to the operation input unit 14. The water outlet to which the water supply port 27 faces is switched among the plurality of water outlets 26a to 26i. In the water discharge part 26, water is discharged only from one water discharge port with which the water supply port 27 opposes among the some water discharge ports 26a-26i. The water discharge area | region change process part 51 switches one water outlet from which water is discharged among several water outlet 26a-26i by moving the water supply cylinder 22 in the axial direction and the circumferential direction in the water supply cylinder storage part 21a. . Thereby, the water discharge area | region change process part 51 changes the water discharge area | region where water is discharged from the water discharge part 26 of the washing nozzle 18, and also the area | region where the water discharged from the water discharge part 26 hits in the washing | cleaning object.

  Further, when the water supply cylinder 22 is moved to the front end side, that is, the front side of the toilet seat device 10, the control device 41 stops driving the first water supply cylinder motor 24 when the movement regulating component 31 comes into contact with the front end side touch sensor 29. Thus, the movement of the water supply cylinder 22 toward the tip side is stopped. On the other hand, the control device 41 drives the first water supply cylinder motor 24 when the movement restricting component 31 comes into contact with the base end side touch sensor 30 when the water supply cylinder 22 is moved to the base end side, that is, the rear side of the toilet seat device 10. Thus, the movement of the water supply cylinder 22 toward the base end side is stopped. Thus, the control device 41 is configured to reciprocate the water supply cylinder 22 within the range of the axial length of the movement restricting portion 28. That is, the range of the reciprocating movement of the water supply cylinder 22 is restricted by the range of the axial length of the movement restricting portion 28.

  Next, an operation example by the toilet seat apparatus 10 will be described. The operation input unit 14 is provided with a normal mode cleaning switch 14a and a diffusion mode cleaning switch 14b as cleaning switches for performing a cleaning operation for cleaning the user's buttocks. The operation input unit 14 is provided with a stop switch 14c as a switch for stopping the cleaning operation.

  The control device 41 stops the driving of the water supply pump 42 when the stop switch 14c is operated during the execution of the cleaning operation. Further, the control device 41 controls the driving of the nozzle motor 23 to retract the cleaning nozzle 18 to the storage position stored below the toilet seat 15. The control device 41 moves the water supply cylinder 22 to a predetermined initial position by controlling driving of the first water supply cylinder motor 24 and the second water supply cylinder motor 25. In a state where the water supply cylinder 22 has moved to the initial position, the water supply port 27 of the water supply cylinder 22 faces the water discharge port 26 a at the center of the nozzle body 21. That is, in the state where the cleaning nozzle 18 is stored in the storage position, that is, when the cleaning operation is not performed, the control device 41 is in a state where the water supply port 27 of the water supply cylinder 22 is opposed to the central water discharge port 26a. To do.

  When the normal mode cleaning switch 14a is operated, the control device 41 executes the cleaning operation in the normal mode. In this normal mode, the control device 41 controls the drive of the nozzle motor 23 to advance the cleaning nozzle 18 to a protruding position protruding from below the toilet seat 15. Then, the control device 41 drives the water supply pump 42 to supply water to the water supply cylinder 22 on the condition that the seating sensor 17 detects that the user is seated on the toilet seat 15. Thereby, water discharges from the water outlet 26a at the center of the nozzle main body 21, and the user's buttocks are washed with the discharged water.

  In this normal mode, the control device 41 does not drive the first water supply cylinder motor 24 and the second water supply cylinder motor 25. Therefore, in the normal mode, a state in which water is discharged from the water outlet 26a at the center of the nozzle main body 21 and water is not discharged from the other water outlets 26b to 26i is maintained. The water discharge area from which water is discharged does not change. In this normal mode, the control device 41 may reciprocate the cleaning nozzle 18 along the front-rear direction by controlling the driving of the nozzle motor 23.

  On the other hand, when the diffusion mode cleaning switch 14b is operated, the control device 41 performs a cleaning operation in the diffusion mode. In this diffusion mode, the control device 41 controls the drive of the nozzle motor 23 to advance the cleaning nozzle 18 to a protruding position protruding from below the toilet seat 15. Then, the control device 41 drives the water supply pump 42 to supply water to the water supply cylinder 22 on the condition that the seating sensor 17 detects that the user is seated on the toilet seat 15. Thereby, water discharges from the water outlet 26a at the center of the nozzle main body 21, and the user's buttocks are washed with the discharged water.

  In this diffusion mode, the control device 41 also controls driving of the first water supply cylinder motor 24 and the second water supply cylinder motor 25. For this reason, as the first water supply cylinder motor 24 and the second water supply cylinder motor 25 are driven, the water supply cylinder 22 moves in the axial direction or rotates around the axis in the nozzle main body portion 21. Among the plurality of water outlets 26a to 26i of the section 21, one water outlet facing the water inlet 27 of the water supply cylinder 22 is sequentially switched. Thereby, the water discharge area | region where water is discharged in the water discharge part 26 comes to change. Also in this diffusion mode, the control device 41 may reciprocate the cleaning nozzle 18 along the front-rear direction by controlling the driving of the nozzle motor 23. Further, the control device 41 regularly controls the driving of the first water supply cylinder motor 24 and the second water supply cylinder motor 25 so that the water discharge ports 26a to 26i opposed to the water supply port 27 are switched regularly. Alternatively, the water outlets 26a to 26i opposed to the water supply port 27 may be switched randomly by performing random control.

  Next, a directing mode of the plurality of water discharge ports 26a to 26i in the water discharge unit 26, in other words, a design example of the inclination angle will be described. That is, as illustrated in FIG. 6, when the surface S exists at a position away from the water discharge portion 26 of the cleaning nozzle 18 by a predetermined distance D, the water is discharged from one of the plurality of water discharge ports 26 a to 26 i. The directivity of the plurality of water outlets 26a to 26i may be designed so that a part of the area where the water hits the surface S and a part of the area where the water discharged from the other water outlet hits the surface S overlap each other.

  In the design example shown in FIG. 6, a part of the region R1 where the water discharged from the water outlet 26a hits the surface S and a part of the region R2 where the water discharged from the other outlet 26e hits the surface S mutually. They are overlapping. Further, a part of the region R1 where the water discharged from the water outlet 26a hits the surface S and a part of the region R3 where the water discharged from the other outlet 26f hits the surface S overlap each other.

  In this way, the directivity angle of the water discharge port 26e may be designed so that a part of the region R1 and a part of the region R2 overlap, and the discharge is performed so that a part of the region R1 and a part of the region R3 overlap. The directivity angle of the water port 26f may be designed. In addition, although not shown in figure, also about the other water outlets 26b-26d, 26g-26h, each of the water outlets so that a part of area | region where the water discharged from each water outlet hits the surface S may mutually overlap. It is advisable to design the directional pattern. The regions where the water discharged from the plurality of water discharge ports 26a to 26i respectively contact the surface S overlap each other, so that it is possible to avoid the generation of a region where the water does not hit in the site to be cleaned, and the gaps are spread over a wider range. Cleaning can be performed without any problems.

  In addition, as illustrated in FIG. 7, when the surface S exists at a position away from the water discharge portion 26 of the cleaning nozzle 18 by a predetermined distance D, the water is discharged from one of the plurality of water discharge ports 26 a to 26 i. A part of the diffusion region where the water hits the surface S and further diffuses along the surface S and a part of the diffusion region where the water discharged from the other spouts hits the surface S and further diffuses along the surface S mutually It is preferable to design the directivity of the plurality of water outlets 26a to 26i so as to overlap with each other.

  In the design example shown in FIG. 7, a part of the diffusion region R1a in which the water discharged from the water discharge port 26a hits the surface S and further diffuses along the surface S, and the water discharged from the other discharge ports 26e is the surface S. Further, a part of the diffusion region R2a that diffuses along the surface S overlaps each other. Further, a part of the diffusion region R1a where the water discharged from the water discharge port 26a hits the surface S and further diffuses along the surface S, and the water discharged from the other discharge ports 26f hits the surface S and further reaches the surface S. A part of the diffusion region R3a diffusing along it overlaps each other.

  In this way, the directivity angle of the spout 26e may be designed so that a part of the diffusion region R1a and a part of the diffusion region R2a overlap each other, and a part of the diffusion region R1a and a part of the diffusion region R3a The directivity angle of the water discharge port 26f may be designed so as to overlap. In addition, although not shown in figure, also about the other water outlets 26b-26d and 26g-26h, a part of diffusion area where the water discharged from each water outlet hits the surface S and further diffuses along the said surface S mutually. It is preferable to design the directivity of each water outlet so that they overlap each other. When the water discharged from each of the plurality of water discharge ports 26a to 26i hits the surface S and the diffusion regions where the water diffuses along the surface S overlap with each other, a region where the water does not hit is generated in the site to be cleaned. It is possible to avoid this, and it is possible to perform cleaning without gaps over a wider range.

  In the design examples shown in FIGS. 6 and 7, the surface S is simply assumed to be the “surface” of the user's buttocks placed on the toilet seat 15 to be cleaned. Further, the predetermined distance D is set to a distance that is normally assumed as a distance between the user's buttocks placed on the toilet seat 15 to be cleaned and the tip of the cleaning nozzle 18 that has advanced to the protruding position, that is, the water discharge unit 26. For example, a distance of about 5 to 20 cm may be set.

  The toilet seat device 10 according to the present embodiment moves the water supply cylinder 22 in the cleaning nozzle 18 and switches one water outlet to which the water outlet 27 faces among the plurality of water outlets 26a to 26i. The water discharge area where water is discharged is changed. In this case, the toilet seat apparatus 10 moves the water supply cylinder 22 in the cleaning nozzle 18 along the axial direction of the cleaning nozzle 18, and also moves the water supply cylinder 22 in the cleaning nozzle 18 along the axis of the cleaning nozzle 18. By rotating to the center, the water discharge region is changed by switching one water discharge port opposed to the water supply port 27 among the plurality of water discharge ports 26a to 26i.

  That is, according to the toilet seat apparatus 10 according to the present embodiment, in the configuration in which the cleaning nozzle 18 is provided with a plurality of water outlets 26a to 26i, the water pressure is maintained by using one water outlet from which water is discharged. However, the water discharge area is changed by switching one water outlet from which the water is discharged. According to this configuration, in the configuration in which the cleaning nozzle 18 is provided with the plurality of water discharge ports 26a to 26i, the cleaning area can be increased without reducing the momentum of the water to be discharged.

  Further, according to the toilet seat device 10, it is not necessary to provide a plurality of water discharge paths in the cleaning nozzle 18, and it is not necessary to provide blades in the cleaning nozzle 18, and the configuration of the cleaning nozzle 18 is different from the conventional configuration. The cleaning nozzle 18 can be made compact. Further, as the cleaning nozzle 18 is made compact, the nozzle motor 23 that drives the cleaning nozzle 18 can be made compact. In addition, since the water supply cylinder 22 is also made compact with the cleaning nozzle 18 being made compact, the first water supply cylinder motor 24 and the second water supply cylinder motor 25 that drive the water supply cylinder 22 can be made compact. Thereby, the washing nozzle 18 can be further downsized.

  Further, according to the toilet seat device 10, the water supply area 22 is changed by moving the water supply cylinder 22 in the cleaning nozzle 18 in accordance with the operation input to the operation input unit 14. According to this configuration, unlike the conventional configuration in which the user manually rotates the member at the nozzle tip, the user's selection operation via the operation input unit 14 is performed on the discharge mode of water from the cleaning nozzle 18. That is, switching can be easily performed according to whether or not the diffusion mode cleaning switch 14b is operated.

Moreover, according to the toilet seat apparatus 10, the water outlets 26a to 26i are directed in different directions. According to this configuration, water is discharged from the water discharger 26 in a plurality of different directions, and the cleaning area can be further increased.
In addition, according to the toilet seat device 10, the plurality of water outlets 26a to 26i are designed so that the regions where the water discharged from the plurality of water outlets 26a to 26i respectively correspond to the object to be cleaned overlap with each other. It is possible to avoid the occurrence of an area where water does not hit the part, and it is possible to perform cleaning without gaps over a wider range.

  Further, according to the toilet seat apparatus 10, the water discharged from the plurality of water discharge ports 26a to 26i hits the object to be cleaned and further diffuses along the surface of the object to be cleaned so as to overlap each other. By designing the water ports 26a to 26i, it is possible to avoid the occurrence of a region where water does not hit in the site to be cleaned, and it is possible to perform cleaning without gaps over a wider range.

(Second Embodiment)
As illustrated in FIG. 8, in this embodiment, the water discharge portion 26 of the cleaning nozzle 18 is provided with a plurality of, in this case, three water discharge ports 26 a, 26 c, and 26 h. That is, the cleaning nozzle 18 has a configuration in which three water outlets 26 a, 26 c, and 26 h are arranged along a direction orthogonal to the axial direction of the nozzle body 21. Then, the control device 41 controls the driving of the second water supply cylinder motor 25 to rotate the water supply cylinder 22 around the axis of the cleaning nozzle 18 in the cleaning nozzle 18. Thereby, the control apparatus 41 switches the one water outlet which the water inlet 27 of the water supply cylinder 22 opposes among the water outlets 26a, 26c, and 26h.

  In addition, the control device 41 controls the driving of the nozzle motor 23 so that the nozzle body 21 is moved in the direction of the arrow A1 and the direction of the arrow A2 along the axial direction of the cleaning nozzle 18, in other words, the front-rear direction of the toilet seat device 10. Move back and forth. That is, the control device 41 moves the nozzle body 21 by a predetermined amount in the direction of the arrow A1, thereby moving the water outlets 26a, 26c, 26h to positions corresponding to the water outlets 26f, 26d, 26i described above. In addition, the control device 41 moves the nozzle body 21 by a predetermined amount in the direction of the arrow A2, thereby moving the plurality of water outlets 26a, 26c, and 26h to positions corresponding to the water outlets 26e, 26b, and 26g described above. As a result, the control device 41 apparently switches the water outlet 27 opposed to the water inlet 27 to one of the water outlets 26f, 26d, 26i and any one of the water outlets 26e, 26b, 26g. Form the same state.

  According to the toilet seat device 10 according to the present embodiment, even if the number of water discharge ports provided in the water discharge unit 26 is reduced, the water discharge unit 26 controls the driving of the nozzle motor 23 together with the second water supply cylinder motor 25. The water discharge area where water is discharged can be changed, and the cleaning area can be increased without reducing the momentum of the discharged water.

  Further, the toilet seat device 10 may have a configuration in which a bidet cleaning nozzle is provided alongside the cleaning nozzle 18. That is, the toilet seat apparatus 10 may be configured to include a nozzle for cleaning a portion different from the cleaning target portion assumed by the cleaning nozzle 18 such as a bidet cleaning nozzle. In this case, the toilet seat apparatus 10 may have a configuration in which a plurality of different water discharge paths are provided for each site to be cleaned, and all of these water discharge paths are provided inside the cleaning nozzle 18. A water discharge path for cleaning, that is, a water discharge path mainly composed of the water supply cylinder 22 is provided inside the cleaning nozzle 18, and a water discharge path for cleaning a part different from the target part to be cleaned assumed by the cleaning nozzle 18 is provided in the cleaning nozzle 18. It is good also as a structure provided outside.

  In addition, as illustrated in FIG. 9, a plurality of small holes may be provided in the plurality of water discharge ports 26 a to 26 i, respectively. According to this configuration, since the flow resistance of the water discharged from the water discharge ports 26a to 26i increases, water can be discharged from the respective water discharge ports 26a to 26i while being further diffused.
