 If the user is not seated on the toilet seat 13, the seating detection switch 200 does not transmit a signal indicating that the user is seated to the control device 700. In this case, the control device 700 does not operate the nozzle device 15, the drying device 120, the deodorizing device 162, and the toilet seat 13.

[0068] When the user is seated on the toilet seat 13, the seating detection switch 200 transmits a signal indicating that the user is seated to the control device 700. In this case, the control device 700 operates the deodorizing device 162 and makes the nozzle device 15 and the drying device 120 operable. [0069] When the user performs a local cleaning operation using the operation unit 11 or the remote controller 40, the nozzle device 15 ejects cleaning water. The detailed operation of the nozzle device 15 will be described later. As a result, local cleaning is performed. When the user performs the cleaning end operation, the cleaning operation by the nozzle device 15 ends.

 [0070] When the user performs a drying operation using the operation unit 11 or the remote controller 40, the control device 700 operates the drying device 120. Thereby, the warm air blows out toward the user's local area. When the user completes the drying operation, the drying device 120 stops.

 [0071] The earth leakage breaker 300 supplies power to the control device 700, the nozzle device 15, the washing water tank 116, the drying device 120, the deodorizing device 162, the toilet seat toilet lid opening / closing device 163, and the toilet seat 13 when an earth leakage is detected. Shut off.

 [0072] (2) Nozzle device

 (2-1) Overall configuration of nozzle device 15

 FIG. 3 is an external perspective view of the entire nozzle device, and FIG. 4 is a perspective view of the nozzle device with the upper case removed. Fig. 5 is a perspective view of the nozzle device at the butt cleaning position, and Fig. 6 is a perspective view of the nozzle device at the bidet cleaning position.

As shown in FIG. 3, the nozzle device 15 has a casing 16 molded from a resin material.

 The casing 16 includes an upper case 17 and a lower case 18 that are separable in the vertical direction. Figure

4 shows a state in which the upper case 17 is removed.

As shown in FIG. 4, a substantially cylindrical nozzle guide 19 is formed at the center of the lower case 18. A tip opening 20 is provided at one end of the nozzle guide 19. A cylindrical nozzle unit 21 is slidably provided in the nozzle guide 19.

The nozzle unit 21 includes a substantially cylindrical nozzle body 22, a substantially cylindrical nozzle cover 23 that accommodates the nozzle body 22, and a connecting mechanism 24 for pulling the nozzle cover 23 by the nozzle body 22. Prepare.

[0076] The nozzle unit 21 includes a storage position (the position shown in FIGS. 3 and 4) housed in the nozzle guide 19 and a cleaning position protruding from the tip opening 20 (the butt cleaning position in FIG. 5 and FIG. 6). It is possible to move forward and backward between the bidet cleaning position. [0077] In the vicinity of the tip opening 20 of the nozzle guide 19, a cleaning enlarged portion 40a having a large inner diameter is formed. The cleaning enlarged portion 40a has a depth that sufficiently covers the buttocks cleaning outlet 31 and the nozzle cleaning outlet 33 (FIG. 9 to be described later) when the nozzle unit 21 is housed. The inner diameter of the cleaning enlarged portion 40a is set to a dimension that forms a slight gap around the entire circumference with the outer surface of the nozzle cover 23. As a result, cleaning water for nozzle cleaning can be passed through the gap. In addition, a drain port 41 for discharging cleaning water is formed in the lower part of the cleaning enlargement section 40a.

 The nozzle guide 19 of the casing 16 accommodates a nozzle unit 21 including a nozzle body 22, a nozzle cover 23, and a coupling mechanism 24. The rear part of the nozzle guide 19 has an inner diameter that is slightly larger than the outer diameter of the nozzle cover 23. That is, the nozzle cover 23 and the nozzle guide 19 have a dimensional relationship that allows them to slide smoothly.

 [0079] As shown in FIGS. 5 and 6, a nozzle shutter 42 that is rotatable up and down is attached to an upper portion of the tip opening 20 of the nozzle guide 19. In the state shown in FIG. 3 in which the nozzle unit 21 is housed in the nozzle guide 19, the nozzle shutter 42 closes the tip opening 20. As shown in FIGS. 5 and 6, when the nozzle unit 21 advances to the cleaning position, the nozzle shutter 42 is pushed upward by being pushed by the tip of the nozzle unit 21. As shown in FIG. 3, when the nozzle unit 21 is housed in the nozzle guide 19, the nozzle shutter 42 rotates downward by its own weight and closes.

 [0080] (2-2) Configuration of nozzle unit 21

 7 is a detailed sectional view of the tip of the nozzle unit 21, FIG. 8 is a sectional view taken along the line AA in FIG. 7, FIG. 9 is a sectional view taken along the line BB in FIG. 7, and FIG. 11 is an exploded perspective view of the nozzle body 22 with the nozzle lid removed.

 As shown in FIG. 8, a butt cleaning channel 28, a bidet cleaning channel 29, and a nozzle cleaning channel 30 are formed inside the nozzle body 22. In order to form three flow paths in the nozzle body 22, the butt cleaning flow path 28 and the nozzle cleaning flow path 30 are arranged symmetrically with respect to the center plane of the nozzle body 22, and the bidet cleaning flow path 29 Is arranged at a position where the central axial force of the nozzle body 22 is also shifted in the vertical direction. A tooth-shaped rack 34 is formed on the lower surface of the nozzle body 22 over substantially the entire length (see FIGS. 14 to 16 described later).

[0082] As shown in FIG. 7, the base of the nozzle body 22 is composed of a large diameter portion 25, and the tip is a bidet nozzle. It consists of part 26 (see Fig. 10). The large diameter portion 25 has a larger outer shape than the bidet nozzle portion 26. As shown in FIG. 9, unlike the central position of the large diameter portion 25 and the central position of the bidet nozzle portion 26, the bidet nozzle portion 26 is disposed below the large diameter portion 25.

 The large diameter portion 25 has an outer diameter that is slightly smaller than the inner diameter of the nozzle cover 23. The outer diameter of the large-diameter portion 25 is set to a dimension that allows the nozzle body 22 and the nose cover 23 of FIGS. 5 and 6 to smoothly slide relative to each other. The nozzle body 22 is molded from a resin material. The entire bidet nozzle 26 is covered with a stainless steel cover 27.

 The butt cleaning channel 28 extends from the base of the nozzle body 22 to the vicinity of the tip of the large diameter portion 25. The tip of the buttocks cleaning channel 28 communicates with the buttocks cleaning jet 31 on the upper surface of the large diameter portion 25. The bidet cleaning flow path 29 extends from the base portion of the nozzle body 22 to the substantially distal end portion of the bidet nozzle portion 26 of the large diameter portion 25. The tip of the bidet cleaning channel 29 communicates with a plurality of bidet cleaning jets 32 on the upper surface of the bidet nozzle portion 26.

 The nozzle cleaning flow path 30 in FIGS. 8 and 9 extends from the base portion of the nozzle body 22 to the substantially leading end portion of the large diameter portion 25. As shown in FIG. 9, the large-diameter portion 25 is formed with an internal cleaning jet 33a that opens downward, and the nozzle lid 22b is formed with an external cleaning jet 33b that opens upward on the side surface. The inner cleaning outlet 33a and the outer cleaning outlet 33b constitute the nozzle cleaning outlet 33. The direction in which the washing water is ejected from the inner washing outlet 33 a and the outer washing outlet 33 b is offset with respect to the diameter direction of the nozzle body 22. The tip of the nozzle cleaning channel 30 communicates with the nozzle cleaning outlet 33.

 [0086] The buttocks cleaning jet 31 has a two-stage shape including an inner large hole portion 3la having a large opening area and an outer small hole portion 31b having a small opening area. The opening area of the large hole 31a is approximately twice the opening area of the small hole 3 lb.

 [0087] The portion between the large hole portion 3 la and the small hole portion 3 lb has a right-angled edge shape. Such an edge shape facilitates separation of the flow of cleaning water. As a result, the flow of cleaning water becomes intermittent, and the cleaning water intermittently hits the local area. As a result, the cleaning power is enhanced and a strong cleaning feeling is generated in the human body. As a result, the user can feel a load stronger than the load that is actually applied to the local area, and can obtain high satisfaction.

[0088] The smaller the thickness of the small hole portion 31b, the more likely the flow separation occurs, and the flow becomes intermittent. Although the regulation of the jet direction is weak, the jet is likely to diffuse. On the contrary, the greater the thickness of the small hole portion 31b, the less the intermittent feeling of force that can suppress the diffusion of the jet. Therefore, in the present embodiment, the thickness of the small hole portion 3 lb is set to 0.5 mm as an optimum value that balances the jet diffusion and the intermittent feeling.

 As shown in FIGS. 3 to 6, a cleaning water supply port for supplying cleaning water is provided in the upstream end portion of the hip cleaning channel 28, the bidet cleaning channel 29, and the nozzle cleaning channel 30. 28a, 29a, 30a are provided. The washing water supply ports 28a, 29a, 30a are connected to the flow rate regulating valve 61 in FIG. 6 through the hoses shown in FIG. The flow rate adjusting valve 61 has a function of individually supplying, stopping, and adjusting the flow rate of the cleaning water to the butt cleaning channel 28, the bidet cleaning channel 29 and the nozzle cleaning channel 30, and the cleaning water supply system ( (Not shown) and a hose (not shown). The flow regulating valve 61 has a drive motor controlled by the control device 700.

 [0090] As shown in FIG. 10, the nozzle body 22 includes a nozzle body base material 22a and a nozzle lid 22b. A nozzle lid 22b is attached to the outer peripheral surface of the large diameter portion 25. In the nozzle lid 22b, the above-described buttocks cleaning outlet 31 is formed. On the upper surface of the bidet nozzle portion 26, the plurality of bidet cleaning jets 32 are formed.

 [0091] The buttocks washing outlet 31 is disposed on the center plane of the nozzle body 22. Therefore, as shown in FIG. 11, the buttocks cleaning flow path 28 communicates with the buttocks cleaning spout 31 via the curved portion 28b that is curved in an arc shape in the vicinity of the buttocks cleaning spout 31.

 A rectifying wall 28c concentric with the curved arc is formed closer to the center of the curved arc than the central axis of the flow path in the curved portion 28b. The rectifying wall 28c has a thickness of 0.5 mm, and is formed in a thin and sharp shape at the upstream end and the downstream end. This flow straightening wall 28c is also provided so that the bottom force of the flow path in the curved portion 28b is perpendicular to the nozzle lid 22b.

 In the present embodiment, the nozzle body base material 22a and the nozzle lid 22b are formed by separate parts. A butt cleaning flow path 28 and a rectifying wall 28c are formed on the nozzle body base material 22a. The nozzle lid 22b is bonded to the nozzle body base material 22a so as to cover the open portion of the buttocks cleaning channel 28.

 FIG. 12 is a perspective view of the nozzle cover 23, and FIG. 13 is an exploded perspective view of the nozzle cover 23.

[0095] As shown in Figs. 12 and 13, the nozzle cover 23 is formed of a stainless steel thin plate. A cylindrical nozzle cover main body 23a and a cover rear end member 23b made of a resin molded product. The nozzle cover body 23a is provided with a fixing hole 23e. The cover rear end member 23b has a substantially semi-cylindrical shape with an open lower portion, and has a connecting projection 48 and a positioning projection 51 projecting horizontally on both sides. Fixing protrusions 23d are provided in the vicinity of the open ends on both sides of the cover rear end member 23b.

 [0096] The nozzle cover body 23a and the cover rear end member 23b are joined as follows. The nozzle cover body 23a is covered by overlapping the overlapping portion 23c of the nozzle cover body 23a and the cover rear end member 23b and fitting the fixing protrusion 23d of the cover rear end member 23b into the fixing hole 23e of the nozzle cover body 23a. Fix to the rear end member 23b. The inner diameter of fixing hole 3e is set slightly larger than the outer dimension of fixing protrusion 23d. As a result, assembly is possible even if there is a slight error in the dimensions of the nozzle cover main body 23a or the cover rear end member 23b.

 Further, the overlapping portion 23c of the cover rear end member 23b is formed to have a size smaller than the other portions and substantially equal to the inner surface of the nozzle cover main body 23a. As a result, the cover rear end member 23b and the nozzle cover body 23a are closely polymerized.

 [0098] As shown in FIGS. 3 and 4, a protrusion 23f protruding forward is provided at the center of the upper surface of the cover rear end member 23b, and a recess 23g is provided at the rear end of the nozzle cover body 23a. The protrusion 23f of the cover rear end member 23b engages with the recess 23g of the nozzle cover body 23a, so that the movement of the nozzle cover body 23a in the left-right direction is restricted. The protrusion 23f and the recess 23g are formed with substantially the same dimensions. As a result, even if there is some error in the dimensions of the nozzle cover body 23a or the cover rear end member 23b, the adhesive or bonding member is used with the nozzle cover body 23a and the cover rear end member 23b properly positioned. It can be securely joined without any trouble.

As shown in FIG. 13, the rear end surface of the nozzle cover 23 formed by joining the nozzle cover main body 23a and the cover rear end member 23b is open. Thereby, the nozzle body 22 can be inserted also with the rear end face force of the nozzle cover 23. The tip surface of the nozzle cover 23 is closed, and a bidet nozzle inlet / outlet port 35 through which the bidet nozzle part 26 can pass is provided. As a result, only the bidet nozzle portion 26 of the nozzle body 22 can protrude from the bidet nozzle inlet / outlet port 35. The bidet nozzle part 26 of the nozzle body 22 is substantially the whole from the bidet nozzle inlet / outlet port 35 of the nozzle cover 23. It is possible to shift between the protruding state (Fig. 6) and the housed state (Fig. 5).

[0100] A slit-shaped rack opening 38 is provided at a position corresponding to the rack 34 of the nozzle body 22 at the rear rear surface of the nozzle cover 23, and a drainage port 39 for discharging cleaning water in the nozzle cover 23 is provided at the front lower surface. Provided.

 [0101] As shown in FIG. 9, with the nozzle body 22 housed in the nozzle cover 23, the nozzle body 23 is positioned on the upper surface of the nozzle cover 23 corresponding to the butt cleaning nozzle 31 and the nozzle cleaning nozzle 33. The butt cleaning opening 36 and the nozzle cleaning opening 37 are provided respectively. The washing water ejected from the butt cleaning outlet 31 and the nozzle cleaning outlet 33 passes through the butt cleaning opening 36 and the nozzle cleaning opening 37 without being in direct contact with the nozzle cover 23.

 [0102] (2-3) Drive mechanism of nozzle device 15

 14, FIG. 15 and FIG. 16 are longitudinal sectional views showing the driving state of the nozzle device 15, FIG. 14 shows the storage state, FIG. 15 shows the buttocks washing state, and FIG. 16 shows the bidet washing state.

 As shown in FIG. 14, FIG. 15, and FIG. 16, a nozzle drive device 43 is provided in the lower part of the casing 16. The nozzle drive device 43 includes a drive motor 44, a worm gear (not shown), a speed change gear 45, and a pion gear 46. The pion gear 46 is provided at a position that mates with the rack 34 on the lower surface of the nozzle body 22 through the rack opening 38 (FIGS. 12 and 13) of the nozzle cover 23.

 The rotational force of the drive motor 44 is transmitted to the pion gear 46 through the worm gear and the transmission gear 45 while reducing the rotational speed. As the pinion gear 46 rotates, the nozzle body 22 having the rack 34 is slid. The drive motor 44 is connected to the control device 700 (FIG. 2). The operation of the drive motor 44 is controlled by the control device 700. A rotation detection sensor 47 that detects the number of rotations of the drive motor 44 is provided at the rear of the drive motor 44.

 [0105] (2-4) Details of connecting mechanism 24

 FIGS. 17 to 20 are cross-sectional views showing details of a coupling mechanism for pulling and moving the nozzle cover 23 by the nozzle body 22. FIGS. 21 and 22 are longitudinal sectional views showing details of a coupling mechanism for pulling and moving the nozzle cover 23 by the nozzle body 22.

[0106] As shown in FIGS. 21 and 22, the nozzle body 22 and the nozzle cover 23 include nozzles. A connecting mechanism 24 for pulling and moving the nozzle cover 23 by the movement of the main body 22 is provided. The connection mechanism 24 includes a connection receiving portion 48 formed on one side surface of the cover rear end member 23b and a connection member 49 formed on the rear end portion of the nozzle body 22.

 [0107] The connection receiving portion 48 is formed in parallel with the nozzle cover 23 on one side surface of the cover rear end member 23b by molding a resin material. On the lower surface of the coupling receiving portion 48, a front recessed portion 48a and a rear recessed portion 48b are provided at two positions with a space in the front and rear direction. The distance between the front recessed part 48a and the rear recessed part 48b is substantially equal to the length of the bidet nozzle part 26 of the nozzle body 22! /.

 The connecting member 49 is provided on the side surface of the rear end portion of the nozzle body 22. The nozzle body 22 is molded with a connecting member body 49a. The connecting member main body 49 a is provided with a connecting piece 50 that faces the connecting receiving portion 48. The connecting piece 50 is made of an elastic metal material. The connecting piece 50 has a cantilever structure with one end fixed to the connecting member 49, and has a connecting protrusion 50a at the tip. The connection protrusion 50a has a shape that can be fitted into the front recess 48a and the rear recess 48b of the connection receiver 48. When the connecting protrusion 50a is fitted into the front recessed part 48a or the rear recessed part 48b, the connecting member 49 and the connection receiving part 48 are connected, and the nozzle body 22 and the nozzle force bar 23 can be interlocked.

 As shown in FIGS. 12 and 13, a positioning projection 51 is provided on the side surface of the cover rear end member 23b opposite to the connection receiving portion 48. As shown in FIG. As shown in FIGS. 17 to 20, a front stopper 52 and a rear stopper 53 are provided on the side of the nozzle guide 19 of the casing 16. The positioning protrusion 51 of the cover rear end member 23b regulates the sliding range of the nozzle cover 23 by contacting the front stopper 52 and the rear stopper 53 of the casing 16.

 [0110] In addition, a sliding restriction groove 51a that is long in the front-rear direction is formed at the center of the positioning protrusion 51. As shown in FIGS. 17 to 20, the sliding restriction groove 51a is fitted with a sliding restriction projection 49b provided on the connecting member main body 49a (FIGS. 21 and 22). The slide restricting projection 49b that moves in the slide restricting groove 51a constitutes a movement restricting mechanism 24a that restricts the mutual sliding range between the connecting member 49 and the connecting receiving portion 48.

[0111] Note that the range of movement of the sliding restricting protrusion 49b is set slightly longer than the distance between the front concave portion 48a and the rear concave portion 48b. As a result, when a strong force is applied to the nozzle body 22, the connecting protrusion 50a is prevented from jumping out from the front concave portion 48a or the rear concave portion 48b. Can be stopped.

 [0112] (2-5) Operation of nozzle device 15

 The operation and action of the nozzle device 15 configured as described above will be described.

 [0113] When the nozzle device 15 is not used, the nozzle body 22 is stored. In this case, as shown in FIG. 3, the nozzle body 22 is located at the rearmost part in the nozzle guide 19, and the nozzle cover 23 is also located at the rearmost part of the sliding range. As shown in FIG. 17, the positioning protrusion 51 of the nozzle cover 23 is in contact with the rear stopper 53 on the side of the nozzle guide 19, and both the nozzle body 22 and the nozzle cover 23 are in the most retracted position. At this time, as shown in FIG. 21, the connecting protrusion 50a of the connecting piece 50 is in a state of being fitted into the rear recessed portion 48b of the connecting receiving part 48, and the sliding restricting protrusion 49b is slid as shown in FIG. It is located near the rear end of the restriction groove 51a.

 [0114] When the user operates the operation unit 11 to start cleaning, the control device 700 starts the control operation and rotates the drive motor 44 in Fig. 14 in one direction. When the rotational force of the drive motor 44 is transmitted to the pinion gear 46, the force that the nozzle body 22 having the rack 34 meshed with the pinion gear 46 tries to move backward. The position of the nozzle body 22 in the front-rear direction does not change. With this position as the origin, the subsequent position of the nozzle body 22 is controlled. Specifically, the rotational speed of the drive motor 44 is detected by the rotational speed detection sensor 47, and the movement amount of the nozzle body 22 is estimated from the detected rotational speed. Based on the estimated movement amount, the position of the nozzle body 22 can be controlled.

 Next, the control device 700 moves the nozzle body 22 forward by rotating the drive motor 44 in the reverse direction. At this time, as shown in FIG. 21, the nozzle cover 23 is pulled by the nozzle body 22 by keeping the connection protrusion 50a of the connection piece 50 in the state of being inserted into the rear recess 48b of the connection receiving portion 48. Move forward with the nozzle cover 23 integrated.

[0116] When the user selects the buttocks cleaning, the nozzle body 22 and the nozzle cover 23 move forward as shown in FIGS. Then, according to a preset control sequence, when the rotational speed of the drive motor 44 reaches the set value after the origin state, the nozzle body 22 and the nozzle cover 23 are stopped. At this time, as shown in FIG. The 23 positioning protrusions 51 are stopped before the front stopper 52 on the side of the nozzle guide 19. This position of the nozzle body 22 and nozzle cover 23 is the standard position for butt washing.

 [0117] The switching of the cleaning water supply flow path and the adjustment of the flow rate of the cleaning water are performed by the flow rate adjusting valve 61. In the above state, the control device 700 controls the flow rate adjusting valve 61 in FIG. 5 so that the cleaning water is supplied to the buttocks cleaning flow path 28. Thereby, the butt cleaning is started. Wash water that has flowed into the buttocks cleaning channel 28 passes through the curved portion 28b of FIG.

 In this case, generally, when the cleaning water passes through the curved portion 28b, the flow rate on the outer peripheral side of the cleaning water increases and the flow rate on the inner peripheral side decreases in the curved portion 28b. As a result, turbulence is generated by the stagnation of the flow on the inner wall of the buttocks cleaning channel 28. That is, the washing water is disturbed at the curved portion 28b and generates a velocity gradient. As a result, the washing water ejection direction from the buttocks washing ejection port 31 becomes unstable and cannot be properly ejected toward the local area.

 [0119] In order to avoid such a phenomenon, in the present embodiment, a rectifying wall 28c is provided on the bending portion 28b. As a result, the flow on the outer peripheral side and the flow on the inner peripheral side of the cleaning water are separated, and a rectifying effect is generated. In this way, turbulence can be reduced. As a result of verifying the appropriate position of the rectifying wall 28c through experiments, it has been found that the rectifying effect is maximized by providing the rectifying wall 28c slightly inside the flow path central force of the curved portion 28b. Therefore, in this embodiment, the rectifying wall 28c is provided slightly inside the flow path central force of the curved portion 28b.

 [0120] The wash water that has passed through the curved portion 28b is ejected from the butt washing spout 31 toward the local area of the user seated. In the present embodiment, as shown in FIG. 7 and FIG. 9, the buttocks cleaning outlet 31 has a two-stage shape including a large hole portion 31a and a small hole portion 31b. As described above, the opening area of the butt washing outlet 31 changes stepwise, so that the flow rate of the washing water changes stepwise and turbulence occurs. As a result, the wash water is ejected as an intermittent flow and hits the local area. As a result, it is possible to obtain an effect that the user feels a load stronger than the load actually applied to the local area.

[0121] At this time, the upper part of the butt washing outlet 31 and the bidet washing outlet 32 is connected to the nozzle cover 23. Therefore it is covered. Therefore, since the sewage generated by the butt cleaning does not directly cover the butt cleaning outlet 31 and the bidet cleaning outlet 32, the butt cleaning outlet 31 and the bidet cleaning outlet 32 are kept clean.

 [0122] If the sealing performance of the flow control valve 61 (Fig. 3) is insufficient, switching between the butt washing flow path 28 and the bidet washing flow path 29 is not performed completely, and during butt washing. However, a minute amount of washing water will be ejected from the bidet washing outlet 32. In the present embodiment, since the upper force S nozzle cover 23 of the bidet cleaning outlet 32 is covered, the cleaning water is prevented from being ejected from the bidet cleaning outlet 32 to the outside.

 [0123] When the buttocks are being washed, the nozzle motor 22 and the nozzle cover 23 reciprocate back and forth with respect to the standard position by the drive motor 44 alternately repeating forward rotation and reverse rotation. As a result, the wash water can simultaneously wash a wider area of the human body.

 [0124] When the user performs an operation to stop the buttocks cleaning, the drive motor 44 rotates in the reverse direction, and the nozzle body 22 and the nozzle cover 23 move backward to return to the original storage state.

 [0125] Next, when the user selects bidet cleaning, the nozzle body 22 and the nozzle cover 23 move forward after the origin position of the nozzle body 22 is confirmed, as in the butt cleaning. As a result, the drive motor 44 rotates. In the case of bidet cleaning, the nozzle body 22 moves further beyond the buttocks cleaning position.

 At this time, as shown in FIG. 19, the positioning projection 51 of the nozzle cover 23 contacts the front stopper 52 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 in FIG. 21 is detached from the rear recess 48b. In order to enable such an operation, it is necessary 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 to remove the connecting protrusion 50a.

[0127] When the connecting protrusion 50a is disengaged from the rear recess 48b, the nozzle body 22 and the nozzle cover 23 are separated from each other. In this case, since the movement of the nozzle cover 23 is restricted by the front stopper 52, only the nozzle body 22 moves forward, and the bidet nozzle portion 26 force of the nozzle body 22 S from the bidet nozzle inlet / outlet 35 on the tip surface of the nozzle cover 23 Start to advance. [0128] When the nozzle body 22 is further moved forward, the connecting protrusion 50a moves toward the front recess 48a. As shown in FIG. 22, when the connecting protrusion 50a is completely inserted into the front recessed portion 48a, the bidet nozzle portion 26 of the nozzle body 22 completely protrudes from the bidet nozzle inlet / outlet port 35 as shown in FIGS. To do.

 [0129] At this time, position control based on the number of rotations of the drive motor 44 is performed according to a preset control sequence so that the forward movement of the nozzle body 22 is completed. If the drive motor 44 tries to move the nozzle body 22 further forward due to malfunction, the sliding restriction projection 49b of the movement restricting mechanism 24a abuts against the front end of the sliding restricting groove 51a. As described above, the movement of the nozzle body 22 forward is restricted. Therefore, the connection protrusion 50a is prevented from coming off from the front recess 48a.

 [0130] In this way, the nozzle body 22 is moved backward by slightly rotating the drive motor 44 in a state where the connection protrusion 50a is fitted in the front recess 48a. When the nozzle body 22 moves to the bidet cleaning standard position shown in FIG. 20, the drive motor 44 is stopped.

 [0131] When the nozzle main body 22 reaches the bidet cleaning standard position, the control device 700 controls the flow rate adjustment valve 61 so that the cleaning water is supplied to the bidet cleaning flow path 29. Thereby, bidet cleaning is started.

 [0132] At this time, the upper part of the buttocks cleaning jet 31 is covered with the nozzle cover 23. As a result, the sewage generated by the bidet washing is not directly applied to the buttocks washing spout 31, so that the buttocks washing spout 31 is kept clean.

 [0133] If the sealing performance of the flow control valve 61 (Fig. 3) is insufficient, the butt cleaning flow path 28 and the bidet cleaning flow path 29 are not completely switched, and the bidet cleaning is in progress. In addition, a minute amount of washing water spouts out from the butt washing outlet 31. In the present embodiment, since the upper part of the buttocks cleaning jet 31 is covered with the nozzle cover 23, the cleaning water is prevented from being ejected from the buttocks cleaning jet 31 to the outside.

 [0134] When the bidet cleaning is performed, the nozzle motor 22 and the nozzle cover 23 reciprocate back and forth with respect to the standard position by the drive motor 44 alternately repeating forward rotation and reverse rotation. Thereby, the washing water can simultaneously wash a wider area of the local part of the human body.

[0135] When the user performs an operation to stop the bidet cleaning, the drive motor 44 rotates in the reverse direction, and the nozzle body 2 2 and the nozzle cover 23 start moving backward. During the process of moving the nozzle body 22 and the nozzle force bar 23 backward for storage, the positioning projection 51 of the nozzle cover 23 comes into contact with the rear stopper 53 on the side of the nozzle guide 19, and the nozzle cover 23 is removed. It cannot move after this. When the nozzle body 22 is further moved rearward, the connection protrusion 50a of the connection piece 50 in FIG. 22 is detached from the front recess 48a. In order to be able to perform such an operation, it is necessary that the driving torque of the driving motor 44 for moving the nozzle body 22 in the front-rear direction is larger than the load value required to remove the connecting protrusion 50a.

 [0136] When the connecting protrusion 50a is disengaged from the front recessed portion 48a, the nozzle body 22 and the nozzle canopy 23 are separated from each other by the force S. In this case, since the movement of the nozzle cover 23 is regulated by the rear stopper 53, only the nozzle body 22 moves backward, and the bidet nozzle portion 26 of the nozzle body 22 is located inside the bidet nozzle inlet / outlet 35 at the tip surface of the nozzle cover 23. It starts to be stored.

 [0137] When the nozzle main body 22 is further moved rearward, the connecting protrusion 50a is moved toward the rear recessed portion 48b. As shown in FIG. 21, when the connecting projection 50a is completely inserted into the rear recessed portion 48b, the bidet nozzle portion 26 of the nozzle body 22 is completely inserted into the interior of the bidet nozzle inlet / outlet 35 as shown in FIG. 3, FIG. 14, and FIG. It is stored in.

 [0138] At this point, the nozzle body 22 contacts the rear end of the nozzle guide 19 and cannot move any further. The rotation of the drive motor 44 is stopped by position control based on the rotation speed of the drive motor 44 according to a preset control sequence.

 [0139] When the butt cleaning and the bidet cleaning are completed and the nozzle body 22 stops at the storage position, the control device 700 starts control of the nozzle cleaning. In this case, the control device 700 switches the flow rate adjustment valve 61 so that the cleaning water is supplied to the nozzle cleaning flow path 30. As a result, nozzle cleaning is started. The flow rate of the cleaning water is adjusted by the flow rate adjustment valve 61.

[0140] When cleaning water is supplied to the nozzle cleaning channel 30, two nozzle cleaning jets 33 (internal cleaning jets 33a) provided at the front end of the large diameter portion 25 of the nozzle body 22 in FIG. And washing water spouts from the external washing outlet 33b). The cleaning water sprayed from the external cleaning outlet 33b provided on the outer surface is sprayed to the outside of the nozzle cover 23 through the nozzle cleaning opening 37 of the nozzle cover 23 and the cleaning of the nozzle guide 19 covering the nozzle cover 23 is expanded. It hits the inner wall of part 40a (see Fig. 4). Splashing cleaning water spouts the outer peripheral wall of the nozzle cover 23 and the buttocks Wash out mouth 31. Further, the cleaning water ejected from the internal cleaning outlet 33a provided downward flows to the side of the bidet nozzle portion 26 of the nozzle body 22 and cleans the surface of the bidet nozzle portion 26 and the bidet cleaning outlet 32.

[0141] At this time, as shown in FIG. 9, since the inner cleaning outlet 33a, the outer cleaning outlet 33b, and the nozzle cleaning opening 37 face the direction in which the diametric force of the nozzle body 22 is also offset, The swirl flow swirls and circulates in the circumferential direction of the nozzle guide 19 and the nozzle cover 23. Thereby, dirt on the nozzle body 22 and the nozzle cover 23 can be effectively removed. The washed water after washing is discharged from the drain port 39 (FIGS. 7, 12, and 13) and the drain port 41 (FIG. 4) provided at the lower portions of the nozzle cover 23 and the nozzle guide 19, respectively.

 [0142] In this manner, the cleaning of the nozzle body 22 and the nozzle cover 23 in the storage position is automatically performed after the user's local cleaning is completed and the nozzle body 22 and the nozzle cover 23 are returned to the storage position. To be implemented.

 It should be noted that the operation unit 11 has a cleaning mode switch in order to more reliably clean dirt adhered to the nozzle body 22 and the nozzle cover 23 using a brush or the like.

 [0144] With the nozzle body 22 and the nozzle cover 23 stored in the storage position, when the user presses the switch in the cleaning mode of the operation unit 11 once, the nozzle unit 21 is cleaned as shown in Fig. 5. Move to position. In this state, the flow rate adjusting valve 61 supplies cleaning water to both the buttocks cleaning flow path 28 and the nozzle cleaning flow path 30 in the nozzle body 22. In this case, the flow rate adjusting valve 61 is controlled so that the flow rate of the cleaning water flowing through the buttocks cleaning flow path 28 is smaller than the flow rate during the buttocks cleaning. As a result, the washing water spouted from the butt washing spout 31 does not jump out of the toilet and does not force the user.

In this state, the user can remove the contaminants adhering to the nozzle force bar 23 by cleaning the nozzle cover 23 with a brush or the like. In addition, since the user can clean the nozzle cover 23 while flowing the cleaning water, it is possible to save the trouble of preparing water for cleaning in advance or moistening the brush etc. with water. In addition, the pollutant removed from the nozzle cover 23 by cleaning with flowing wash water flows directly into the toilet bowl. Therefore, the gap between the butt washing outlet 31 or the nozzle body 22 and the nozzle cover 23 No contaminants get in between and reattach.

 Next, when the switch in the cleaning mode is further pressed once, the nozzle unit 21 moves to the bidet cleaning position as shown in FIG. Normally, when the butt cleaning position force when using the nozzle device 15 is switched to the bidet cleaning position, the nozzle body 22 and the nozzle cover 23 are housed in the nozzle guide 19 from the butt cleaning position and the nozzle cover 23 is cleaned. Later, the nozzle body 22 and the nozzle cover 23 move forward again to the bidet cleaning position. On the other hand, since the cleaning mode is intended to clean the nozzle body 22 and the nozzle cover 23, the nozzle body 22 and the nozzle cover 23 do not need to perform such an operation in the cleaning mode. Therefore, the nozzle body 21 can be switched to the bidet cleaning position more quickly by moving the nozzle body 22 forward as it is in the buttocks cleaning position force. Therefore, the user is not bothered by waiting for the nozzle unit 21 to move.

 In this state, the flow rate adjusting valve 61 supplies cleaning water to both the bidet cleaning flow path 29 and the nozzle cleaning flow path 30 in the nozzle body 22. At this time, the flow rate adjustment valve 61 is controlled so that the flow rate of the cleaning water flowing through the bidet cleaning flow path 29 is smaller than the flow rate during bidet cleaning, as in the case of the butt cleaning position. As a result, the washing water ejected from the bidet washing outlet 32 does not jump out of the toilet and does not force the user. In this state, the user can clean the bidet nozzle portion 26 of the nozzle body 22 using a brush or the like.

 [0148] After the cleaning operation at the bidet cleaning position is completed, when the user presses the switch in the cleaning mode again, the supply of cleaning water is stopped. Then, the nozzle body 22 and the nozzle cover 23 are housed in the nozzle guide 19 and the nozzle cleaning is started in the same manner as the end of the butt cleaning or the bidet cleaning. In this case, the entire outside and inside of the nozzle body 22 and the nozzle cover 23 can be cleaned by supplying cleaning water only to the nozzle cleaning channel 30. Therefore, even when the user uses a detergent or the like at the time of cleaning, all the detergent components adhering to the surfaces of the nozzle body 22 and the nozzle cover 23 are washed away.

 [0149] (2-6) Effect of nozzle device 15

As described above, in the present embodiment, the nozzle body 22 has the butt cleaning ejection port 31, the bidet cleaning ejection port 32, and the nozzle cleaning ejection port 33 through which the cleaning water is ejected, and the butt cleaning channel 28, the bidet A cleaning channel 29 and a nozzle cleaning channel 30 are provided. Also nozzle book A cylindrical nozzle cover 23 that covers the body 22 is provided, and the nozzle cover 23 has a buttocks cleaning opening 36 that faces the buttocks cleaning spout 31. Further, a connecting mechanism 24 for connecting the nozzle body 22 and the nozzle knives 23, a nozzle guide 19 for storing the nozzle body 22 and the nozzle cover 23, and a nozzle driving device 43 for moving the nozzle body 22 back and forth are provided. In this way, the butt cleaning outlet 31, the bidet cleaning outlet 32 and the nozzle cleaning outlet 33, the butt cleaning flow path 28, the bidet cleaning flow path 29 and the nozzle cleaning flow path 30 are collectively provided in the nozzle body 22. The nozzle cover 23 has a simple configuration. Thereby, the nozzle device 15 as a whole has a small and simple structure.

[0150] Also, as the nozzle body 22 and the nozzle cover 23 slide relative to each other, the butt cleaning outlet 31 and the butt cleaning opening 36 are aligned, and the cleaning water from the butt cleaning outlet 31 is cleaned. Is ejected through the ass washing opening 36. Therefore, when the washing water is ejected, the vicinity of the bidet washing outlet 32 and the butt washing outlet 31 of the nozzle body 22 is covered with the nozzle cover 23, and the nozzle body 22 is contaminated with dirty washing water. It is hygienic without any problems.

 [0151] Further, the nozzle cover 23 is fixed by fitting a fixing cover 23d and a fixing hole 23e to a nozzle cover main body 23a made of stainless steel and a cover rear end member 23b by resin molding. Thereby, the nozzle cover main body 23a and the cover rear end member 23b by the resin molding are reliably bonded with a simple configuration without using an adhesive or a bonding member. Also, the nozzle cover body 23a is made of stainless steel, so that it is difficult for dirt to adhere to it. In addition, even if dirt adheres to the nozzle cover main body 23a, the dirt can be easily removed by washing.

 [0152] Further, at the time of bidet cleaning, the cleaning water is ejected in a state in which the bidet nozzle portion 26 protrudes from the front end surface of the nozzle cover 23. Therefore, the cleaning water can be ejected close to the object to be cleaned. However, the washing water can be directly ejected from the bidet washing outlet 32 at the bidet washing where a delicate jet form is desired. Thereby, an optimal ejection form can be realized.

[0153] Further, the nozzle cover 23 is interlocked with the nozzle main body 24 via the coupling mechanism 24 between the storage position and the buttocks cleaning position. As a result, only the nozzle body 22 is driven by the nozzle drive device 43, so that both the nozzle body 22 and the nozzle cover 23 are interlocked. In addition, only the nozzle body 22 can move alone to the bidet cleaning position. In this way, since the two driven objects are driven to their optimum positions by the single nozzle driving device 43, the nozzle device 15 can be downsized and reduced in cost.

 [0154] In addition, the cleaning water ejected from the external jet cleaning outlet 33b of the nozzle cleaning outlet 33 provided in the nozzle body 22 hits the cleaning enlarged portion 40a of the nozzle guide 19 through the nozzle cleaning opening 37. The outer surface of the nozzle cover 23 and the inner surface of the nozzle guide 19 are washed by reflecting off the nozzle guide 19. Further, the cleaning water ejected from the inner cleaning outlet 33 a of the nozzle cleaning outlet 33 is reflected by the nozzle cover 23 to mainly clean the outer surface of the bidet nozzle portion 26 and the inner surface of the nozzle cover 23. Therefore, the self-cleaning mechanism of the nozzle body 22 and the nozzle cover 23 that are contaminated with dirty water or dirt during the butt cleaning and bidet cleaning is realized with a small and simple configuration. Thereby, a sanitary nozzle device 15 is provided.

 [0155] In addition, the user can clean the nozzle body 22 and the nozzle cover 23 using a brush or the like while flowing the washing water by his / her own intention using the cleaning mode. As a result, a high degree of sanitary satisfaction can be given to the user.

 [0156] Further, the rectifying wall 28c is provided in the curved portion 28b of the buttocks cleaning channel 28, so that the turbulent flow in the buttocks cleaning channel 28 is suppressed. Thereby, the direction of the washing water jet from the butt washing outlet 31 can be stabilized, and the washing water can be jetted appropriately toward the local area. Also, since the upstream end portion and the downstream end portion of the rectifying wall 28c have a thin and sharp shape, the flow of the washing water can be smoothly divided and rejoined. In particular, since the downstream end portion of the rectifying wall 28c has a thin and sharp shape, the rectifying effect increases because the divided wash water smoothly merges. Conversely, if an edge remains at the downstream end of the rectifying unit 28c, a vortex is generated due to collision when the divided wash water merges, and flow separation at the edge tends to occur. . As a result, the flow of washing water becomes turbulent.

 [0157] Further, since the buttocks cleaning outlet 31 has a two-stage shape of the large hole portion 31a and the small hole portion 31b, the cleaning water is intermittently flowed and sprayed locally. As a result, the user can feel a higher washing feeling because he / she feels a load stronger than the load which is actually applied to the local area.

[0158] (2-7) Modification In this embodiment, the nozzle driving device 43 includes a transmission mechanism using gears (worm gear, transmission gear 45, and pinion gear 46). However, the transmission mechanism such as a belt or a chain is not limited to this. You can use it.

 [0159] In the present embodiment, the nozzle canopy 23 and the force of forming the cover 27 of the bidet nozzle portion 26 are made of stainless steel. These materials are not limited to stainless steel, but have other corrosion resistance metals. The material may be an inorganic material such as ceramics or a resin material. In particular, the use of a material to which antibacterial performance, bactericidal performance, water repellency performance or the like is added to these materials can further enhance cleanliness.

 [0160] Also, in the present embodiment, the nozzle body 22 has a buttocks cleaning outlet 31, a bidet cleaning outlet 32 and a nozzle cleaning outlet 33, and an buttocks cleaning channel 28 communicating therewith. The force that provides all of the bidet cleaning flow path 29 and the nozzle cleaning flow path 30 is not limited to the above-mentioned cleaning outlets 31, 32, 33 and the cleaning flow paths 28, 29, 30. Nosole cover 23 is formed with a large thickness, and a part of cleaning outlets 31, 32, 33 and cleaning channels 28, 29, 30 (for example, ass cleaning outlet 31 and ass cleaning channel) 28) may be provided on the nozzle cover 23. In other words, the washing water ejection portion may be provided separately for the nozzle body 22 and the nozzle cover 23. In this case, the structure of the nozzle cover 23 is complicated, but the structure of the nozzle body 22 is simple, so that an effect similar to that of the present embodiment can be obtained.

 [0161] In the present embodiment, the connecting piece 50 of the connecting mechanism 24 is formed of an elastic metal material. However, the present invention is not limited to this, and a resin material having elasticity may be used. Yes. When the resin material is used, the connecting member 49 of the connecting mechanism 24 can be integrally molded, and the connecting mechanism 24 can be manufactured at low cost.

[0162] In the present embodiment, the thickness of the rectifying wall 28c is set to 0.5 mm. However, the present invention is not limited to this! /. In general, in order to fabricate the rectifying wall 28c integrally with the nozzle body base material 22a by a resin molding, a thickness of about 0.5 to 1. Omm is required. On the other hand, in order to suppress the pressure loss of the flow path, it is desirable that the rectifying wall 28c be formed as thin as possible. Therefore, in this embodiment, a minimum thickness of 0.5 mm in the above range is adopted. As a method of forming the rectifying wall 28c thinner, the rectifying wall 28c is formed as a separate member with metal or the like. A method of attaching to the curved portion 28b of the buttocks cleaning channel 28 can be used.

 [0163] Further, in the present embodiment, the force is not limited to the force in which the small hole portion 31b has a thickness of 0.5 mm. It has been confirmed that an intermittent flow of washing water can be obtained by setting the thickness of the small hole portion 31b in the range of 0.5 to 1.5 mm, and a desired intermittent flow can be obtained by selecting the thickness. it can. Further, the force in which the opening area of the large hole portion 31a is approximately twice the opening area of the small hole portion 31b is not limited to this. It has been confirmed that an intermittent flow can be obtained by making the opening area of the large hole 31a 1.5 to 2.5 times the opening area of the small hole 3 lb. Optimal by changing the opening area An intermittent flow can be obtained.

 [0164] (2-8) Other examples of nozzle body 22

 FIG. 23 is an exploded perspective view showing another example of the nozzle body 22. The nozzle body 22 force S in FIG. 23 is different from the nozzle body 22 in FIG. 11 in the following points.

 In the nozzle body 22 of FIG. 11, the rectifying wall 28c is formed integrally with the nozzle body base material 22a on the curved portion 28b of the buttocks cleaning flow path 28. On the other hand, in the nozzle body 22 of FIG. 23, only the buttocks cleaning channel 28 is molded integrally with the nozzle body base material 54a, and the rectifying wall 28c is molded integrally with the nozzle lid 22b.

 [0166] In addition, two positioning holes 54c are formed in the nozzle body base material 22a and two positioning bosses 54d are formed in the nozzle lid 22b in order to improve the accuracy of the position of the rectifying wall 28c. Two positioning holes 54c and two positioning bosses 54d are fitted to each other.

 Note that, in FIG. 23, the portions denoted by the same reference numerals as those in FIG. 11 have the same structure, and the description thereof will be omitted.

 [0168] As described above, in the nozzle body 22 of this example, the rectifying wall 28c is molded integrally with the nozzle lid 22b, which is a small component. As a result, the dimensional accuracy of the rectifying wall 28c can be improved, and the molding of the nozzle body base material 22a, which is a large component, can be facilitated. As a result, the productivity of both parts is improved.

 [0169] (2-9) Other example of nozzle device 15

FIG. 24 is a perspective view showing a cross section of the main part of the cover cleaning flow path and the cover cleaning outlet in another example of the nozzle device 15. FIG. 25 is a perspective view showing a cross-section of the main parts of the nozzle cleaning flow path and the nozzle cleaning outlet in another example of the nozzle device 15. The nozzle device 15 of FIGS. 24 and 25 is different from the nozzle device 15 of FIGS. 3 to 22 in the following points.

 In the nozzle device 15 of FIGS. 3 to 22, the cleaning water is ejected from the external cleaning outlet 33b of the nozzle cleaning outlet 33 communicating with the nozzle cleaning flow path 30 of the nozzle body 22, and the nozzle cleaning of the nozzle cover 23 is performed. It is ejected to the outside of the nozzle cover 23 through the opening 37. The sprayed cleaning water hits the inner wall of the cleaning enlarged portion 40a of the nozzle guide 19 that covers the nozzle cover 23, and the outer peripheral wall of the nozzle cover 23 and the butt cleaning spout 31 are cleaned by the rebounding cleaning water. In addition, cleaning water is ejected from the internal cleaning outlet 33a and flows to the side of the bidet nozzle portion 26 of the nozzle body 22, and the surface of the bidet nozzle portion 26 and the bidet cleaning outlet 32 are cleaned.

 On the other hand, in the nozzle device 15 of the present example, as shown in FIG. 24, the cover cleaning flow channel 57 and the cover cleaning jet port 5 8 are formed above the cover cleaning channel 57 of the casing 16 and the upper case 17. Is provided. The cover cleaning outlet 58 opens toward the cleaning enlarged portion 40a of the nozzle guide 19. Further, the cover cleaning jet outlet 58 is provided at a position substantially above the central axis of the nozzle guide 19. The cover cleaning channel 57 and the cover cleaning outlet 58 are used for cleaning the outer surface of the nozzle cover 23.

 On the other hand, as shown in FIG. 25, the nozzle cleaning flow path 30 of the nozzle body 22 communicates with the nozzle cleaning outlet 60 opened downwardly! The direction in which the cleaning water is ejected from the nozzle cleaning outlet 60 is set to be offset with respect to the diameter direction of the nozzle body 22. The nozzle cleaning channel 30 and the nozzle cleaning nozzle 60 are used for cleaning the inner surface of the nozzle cover 23 and the bidet nozzle 26.

 Hereinafter, the operation and action of the nozzle device 15 of FIGS. 24 and 25 will be described. Also in the nozzle device 15 of this example, the switching of the flow path to which the cleaning water is supplied and the adjustment of the flow rate are performed by the flow rate adjustment valve 61 in FIG.

 [0175] With the nozzle body 22 stopped at the storage position, the control device 700 controls the flow rate adjusting valve 61 so that the cleaning water is supplied to the nozzle cleaning channel 30 and the cover cleaning channel 57. Thereby, nozzle cleaning is started.

[0176] The cleaning water supplied to the nozzle cleaning flow path 30 is jetted downward from the nozzle cleaning jet outlet 60 at the front end of the nozzle body 22, and flows to the side of the bidet nozzle section 26 of the nozzle body 22. The As a result, the surface of the bidet nozzle part 26, the inner surface of the bidet cleaning jet 32 and the nozzle cover 23 are cleaned.

 On the other hand, the cleaning water supplied to the cover cleaning flow channel 57 is ejected downward from the cover cleaning outlet 58 and hits the outer peripheral surface of the nozzle cover 23, and the outer peripheral surface of the nozzle cover 23 and the nozzle guide 19 The outer peripheral surface of the nozzle cover 23, the inner peripheral surface of the nozzle guide 19, and the butt cleaning outlet 31 are cleaned while flowing through the gap with the inner peripheral surface of the cleaning enlarged portion 40a.

 [0178] The washing water used for washing is also discharged from the drain 39 (Fig. 12 and Fig. 13) at the bottom of the nozzle cover 23 and the drain 41 (Fig. 4) at the bottom of the nozzle guide 19.

 [0179] The cleaning of the nozzle body 22 and the nozzle cover 23 at the storage position is automatically performed after the nozzle body 22 and the nozzle cover 23 are returned to the storage position after the local cleaning is completed. The operation unit 11 has a cleaning mode switch for operating the cleaning mode in order to more reliably clean dirt adhered to the nozzle body 22 and the nozzle cover 23 using a brush or the like.

 [0180] With the nozzle main body 22 and the nozzle cover 23 stored in the storage position, when the user presses the switch in the cleaning mode of the operation unit 11 once, the nozzle unit 21 moves to the buttocks cleaning position shown in FIG. Moving. In this state, the flow rate adjusting valve 61 supplies cleaning water to the bottom cleaning flow path 28, the nozzle cleaning flow path 30, and the upper cover cleaning flow path 57 of the upper case 17 in the nozzle body 22. In particular, the flow rate of the cleaning water flowing through the buttocks cleaning flow path 28 is controlled to be smaller than the flow rate at the buttocks cleaning. As a result, the washing water spouted from the butt washing spout 31 does not jump out of the toilet bowl or force the user.

 [0181] In this state, the user can remove the contaminants attached to the nozzle cover 23 by cleaning the nozzle cover 23 with a brush or the like. Moreover, since cleaning can be performed while flushing water, it is possible to save the time for preparing water for cleaning in advance and for wetting brushes with water. In addition, since contaminants removed from the nozzle cover 23 by cleaning with flowing cleaning water are directly flowed to the toilet, the gap between the butt cleaning spout 31 or the nozzle body 22 and the nozzle cover 23 is removed. No contaminants can enter and re-adhere.

[0182] Next, when the user presses the cleaning mode switch of the operation unit 11 once, the nozzle unit 21 moves to the bidet cleaning position shown in FIG. During normal use of the nozzle device 15 Switching from the cleaning position to the bidet cleaning position is performed as follows. From the butt cleaning position-After the nozzle body 22 and the nozzle cover 23 are housed in the nozzle guide 19, the nozzle body 22 and the nozzle cover 23 are cleaned, and the nozzle body 22 and the nozzle cover 23 are moved forward again. Move to bidet cleaning position. On the other hand, in the cleaning mode, since the purpose is to clean the nozzle body 22 and the nozzle cover 23, the operation as in normal use is not necessary. Therefore, the nozzle body 22 is moved to the bidet cleaning position earlier by moving the nozzle body 22 as it is also in the buttocks cleaning position force. Therefore, the user force S is not bothered by waiting for the movement of the nozzle body 22.

 In this state, the flow rate adjusting valve 61 supplies cleaning water to the bidet cleaning channel 29, the nozzle cleaning channel 30 and the cover cleaning channel 57 in the nozzle body 22. At this time, the flow rate adjustment valve 61 is controlled so that the flow rate of the cleaning water flowing through the bidet cleaning flow path 29 is smaller than the flow rate during bidet cleaning, as in the case of the buttocks cleaning position. As a result, the washing water ejected from the bidet washing outlet 32 does not jump out of the toilet bowl and does not force the user. In this state, the user can clean the bidet nozzle portion 26 of the nozzle body 22 using a brush or the like.

 [0184] After the cleaning operation at the bidet cleaning position is completed, pressing the cleaning mode switch on the operation unit 11 again stops the supply of cleaning water. Then, the nozzle body 22 and the nozzle cover 23 are accommodated in the nozzle guide 19, and the nozzle cleaning is started in the same manner as the end of the butt cleaning or the bidet cleaning. At this time, the cleaning water is supplied only to the nozzle cleaning channel 30 and the cover cleaning channel 57, so that the entire area outside and inside the nozzle body 22 and the nozzle cover 23 can be sufficiently cleaned. Therefore, even when the user uses a detergent or the like during cleaning, all the detergent components adhering to the surfaces of the nozzle body 22 and the nozzle cover 23 can be washed away.

 [0185] In this example,! /, The nozzle cleaning flow path 30 and the nozzle cleaning ejection port 60 are provided independently inside and outside the nozzle cover 23, respectively. As a result, the outer peripheral surface of the nozzle cover 23 and the bidet nozzle portion 26 inside the nozzle cover 23 can be effectively cleaned by an optimal cleaning method, and the user should use the nozzle device 15 more hygienically. Can do.

[0186] In addition, the user uses the cleaning mode to flow the cleaning water on his / her own will. The nozzle main body 22 and the nozzle cover 23 can be cleaned with, for example. This gives the user a high degree of sanitary satisfaction.

 [0187] In this example, cleaning water is simultaneously supplied to the nozzle cleaning channel 30 and the cover cleaning channel 57. However, the present invention is not limited to this. The nozzle cleaning channel 30 and the cover cleaning channel 57 are individually provided. Wash water may be supplied to the. For example, after the butt cleaning is completed, the outer peripheral surface of the nozzle cover 23 and the butt cleaning outlet 31 are cleaned by supplying cleaning water only to the cover cleaning channel 57, and after the bidet cleaning is completed, The bidet nozzle portion 26 and the inner peripheral wall of the nozzle guide 19 may be cleaned by supplying cleaning water only to the nozzle cleaning flow path 30. Thereby, useless use of cleaning water is suppressed.

 As shown in FIG. 27, the tank main body 122 of the cleaning water tank 116 is integrally formed by welding an upper member 123 and a lower member 124 formed of a resin material to each other.

[0194] The basic shape of the tank body 122 when viewed from the side is a quadrilateral. In particular, the front surface of the tank body 122 has a receding portion 125 that recedes from the front end, and the lower end force of the receding portion 125 is also forward. And an inclined surface 126 inclined obliquely downward. As described above, the front portion of the tank body 122 has a shape in which a portion that becomes an obstacle when the user sits on the toilet seat 13 shown in FIG. A part of the toilet seat 13 is disposed above the inclined surface 126. As a result, the sanitary washing device 10 is configured in a compact manner.

 [0195] A water inlet 127 through which cleaning water flows is provided at the lower front of one side of the tank body 122, and a water outlet 128 through which the cleaning water flows out is provided at the upper rear of the other side of the tank main body 122. It is done. In addition, a vacuum breaker 129 is installed on the upper surface of the tank body 122. The vacuum breaker 129 introduces air as an external force when the pressure inside the tank body 122 becomes negative.

 As shown in FIG. 28, a hot water heater 131 having a U-shaped sheathed heater power is disposed as a heating device for heating the cleaning water at a position near the bottom surface 130 in the lower part in the cleaning water tank 116. A thermistor 132 is arranged near the hot water heater 131 as a temperature detection device for detecting the temperature of the hot water. A heat radiating member 133 is disposed between the hot water heater 131 and the thermistor 132 to transmit the heat of the hot water heater 131 to the thermistor 132.

 [0197] Further, at the lowest position of the bottom surface 130 of the tank body 122, a drain valve 134 capable of discharging all the cleaning water in the tank body 122 is directed obliquely downward from the front end of the tank body 122. Provided. This drain valve 134 is used for preventing freezing in cold regions or for discharging polluted water when not in use for a long time.

 [0198] Inside the water inlet 127 of the tank main body 122, a rectifying mechanism 135 for making the flow of the flowing wash water uniform is provided. The rectifying mechanism 135 is configured by combining a rib formed on the bottom surface 130 of the tank main body 122 and a rectifying member 136 having a rib formed on the lower surface, and changes the cross-sectional area of the flow path and the flow direction.

 FIG. 29 is a sectional view of the cleaning water tank 116, and FIG. 30 is a sectional view of CC in FIG. FIG. 31 is a perspective view showing the inside of the washing water tank 116 in a state where the rectifying member 136 is removed, and FIG. 32 is a perspective view showing the rectifying member 136 with a downward force.

As shown in FIG. 30, a first partition plate 137 that also has a rib force of the rectifying member 136 is formed inside the water inlet 127. The first partition plate 137 constitutes a deflecting unit 1 38 that changes the flow of cleaning water downward. A gap between the lower end of the first partition plate 137 and the bottom surface 130 of the tank body 122 serves as a cleaning water flow path. [0201] On the back side of the first partition plate 137, a second partition plate 139 that also has a rib force standing from the bottom surface 130 of the tank body 122 is formed with a space from the first partition plate 137. A space between the first partition plate 13 7 and the second partition plate 139 serves as the adjustment unit 140. The volume of the adjusting unit 140 is about four times the volume of the deflecting unit 1 38. A gap between the upper end of the second partition plate 139 and the lower surface of the rectifying member 136 serves as a cleaning water flow path.

 [0202] A flow path is formed between the back surface of the second partition plate 139 and the outer peripheral rib 141 of the rectifying member 136, and this flow path becomes the outflow portion 142. The outflow portion 142 is composed of a force lowering portion 143 on the bottom surface 130 of the tank main body 122 and a horizontal portion 144 parallel to the bottom surface 130. The front end of the horizontal portion 144 is opened to the inside of the tank body 122 by force.

 [0203] As shown in Figs. 31 and 32, first partition plate 137, second partition plate 139, and outer peripheral rib 144 each have an L-shape in plan view. As shown in FIG. 30, the gap between the lower end of the first partition plate 137 and the bottom surface 130 of the tank body 122, the gap between the upper end of the second partition plate 139 and the lower surface of the rectifying member 136, and the outflow portion 142 The opening of the horizontal part 144 of the horizontal part is longer and slit-like in the horizontal direction than the height!

 [0204] As shown in Figs. 28 and 29, a plurality of reinforcing ribs 145 extending in the lateral direction are provided on the inner surface of the rear portion of the lower member 124 of the tank body 122. As shown in FIG. 29, the reinforcing rib 145 protrudes toward the inclined opening edge 149 and is formed to be inclined with respect to the bottom surface 130. Since the reinforcing rib 145 protrudes in this direction, molding with a resin material becomes easy. A plurality of reinforcing ribs 146 are also provided outside the bottom surface 130 of the lower member 124. These reinforcing ribs 145 and 146 improve the pressure resistance of the tank body 122.

 [0205] It should be noted that providing the reinforcing ribs 145, 146 on the tank body 122 increases the surface area of the tank body 122, and there is a concern that the heat of the stored wash water may be easily dissipated. However, in the above configuration, the reinforcing rib 145 provided on the rear portion of the lower member 124 of the tank body 122 is present on the inner surface of the tank body 122 and thus hardly affects heat dissipation. In addition, the reinforcing ribs 146 provided outside the bottom surface 130 slightly affect heat dissipation, but since the cleaning water stored at the bottom of the cleaning water tank 116 is at a low temperature, the influence is minimized.

[0206] The joining surface 147 between the upper member 123 and the lower member 124 of the tank body 122 is shown in Figs. 27 and 29. As shown, a substantially diagonal line connecting the upper rear portion and the lower front portion of the tank body 122 is formed. Further, reinforcing edges 150 and 151 projecting outward are provided over the entire outer periphery of the opening edge 148 of the upper member 123 and the opening edge 149 of the lower member 124, which are joint portions. The reinforcing edges 150 and 151 have a thickness larger than that of the surface components such as the side surface, back surface, front surface, and top surface of the tank body 122.

 FIG. 33 is a cross-sectional view of the main part showing an example of the joint portion of the tank main body 122. As shown in FIG. 33, an opening edge 149 of the lower member 124 is provided with an inner circumferential groove 152a and an outer circumferential groove 152b. The inner circumferential groove 152a on the inner side is formed over the entire circumference along the inner circumferential edge 149a of the opening edge 149. The outer peripheral groove 152b is formed in the substantially center of the opening edge 149 over the entire periphery. Metal wires 153 are embedded in the inner circumferential groove 152a and the outer circumferential groove 152b, respectively. The metal wire 153 is energized while the upper member 123 and the lower member 124 are in contact with each other. As a result, the heat generated by the metal wire 153 melts the grease material of the opening edges 148 and 149 in the vicinity of the inner peripheral groove 152a and the outer peripheral groove 152b, and the upper member 123 and the lower member 124 are welded. In this way, the tank body 122 is formed.

 [0208] In particular, in the present embodiment, by providing the inner peripheral groove 152a along the inner peripheral edge 149a of the lower member 124, the inner peripheral edge 148a of the upper member 123, the inner peripheral edge 149a of the lower member 124, and The neighborhood is reliably welded over the entire circumference.

 [0209] Further, in order to further improve the pressure resistance of the joint surface 147 of the tank body 122, the upper member 123 and the lower member 125 are fastened by three screws 170 as shown in FIG.

 [0210] Reinforcing edges 150, 151 provided on the opening edges 148, 149 of the upper member 123 and the lower member 124 contribute to the reinforcement of the pressure resistance of the side surface of the tank body 122. In particular, the lengths of the reinforcing edges 150 and 151 can be maximized by forming the joint surfaces 147 diagonally. Thereby, the reinforcing edges 150 and 151 greatly contribute to the reinforcement of the pressure strength.

 [0211] (3-2) Operation and action of sanitary washing device 10

 Next, operations and actions of the washing water tank 116, the nozzle device 15 and the drying device 120 of the sanitary washing device 10 will be described.

[0212] First, when the user performs a local cleaning operation with the operation unit 11 in a state where a water pipe is connected to the water supply connection unit 117 in FIG. 26, the on-off valve 118 is opened. As a result, tap water is As shown, the water flows into the deflecting unit 138 of the rectifying mechanism 135 at a high flow velocity from the water inlet 127 of the washing water tank 116, turns downward, passes through the gap below the first partition plate 137, and is adjusted. Flows into 140. The washing water flows into the adjusting section 140 having a wide space through a narrow gap, so that the flow velocity is reduced and uniformed, and rectification without turbulence is achieved.

 [0213] Next, the washing water passes through the gap above the second partition plate 139 and flows from the adjustment unit 140 to the outflow unit 144. In this state, the wash water is rectified and the flow velocity is also low. As a result, the washing water flows out from the adjustment unit 140 so as to overflow. The wash water that has flowed out to the outflow portion 142 flows down to the bottom surface 130 of the wash water tank 116 through the descending portion 143, passes through the horizontal portion 144, and flows out along the bottom surface 130 to the inside of the wash water tank 116. To do.

 [0214] The wash water that has flowed into the wash water tank 116 flows below the hot water heater 131 in FIG. The cleaning water heated by the hot water heater 131 gradually rises to the upper part of the cleaning water tank 116. As a result, the heated cleaning water is stored in the upper portion of the cleaning water tank 116.

 [0215] Convection occurs in the wash water tank 116, and the warm wash water rises in the central part of the wash water tank 116, and the cold wash water moves down in the peripheral part. At this time, the plurality of reinforcing ribs 145 at the rear of the tank body 122 act to suppress this convection. As a result, excessive convection in the wash water tank 116 is suppressed, and wash water whose temperature has been raised is always stored in the upper part of the wash water tank 116.

 [0216] When the local cleaning operation is performed, the nozzle unit 21 of the nozzle device 15 has also moved into the cleaning position in the storage position. The temperature of the wash water 116 in the wash water tank 116 that has risen in temperature flows out from a water outlet 128 provided at the upper rear of the tank body 122 and is supplied to the nozzle device 15 through a water pipe. The washing water supplied to the nozzle device 15 passes through the flow regulating valve 161 and passes through the butt washing flow path 28 or the bidet washing flow path 29 of the nozzle body 22 in FIG. It spouts out from the spout 32 toward the local area. As a result, the local area is cleaned.

At this time, the high-temperature cleaning hydraulic power stored in the upper part of the cleaning water tank 116 also flows out sequentially, and the low-temperature cleaning water is not supplied to the nozzle device 15. Therefore, the user can perform comfortable local cleaning. [0218] When the user performs the operation to end the local cleaning, the on-off valve 118 in Fig. 26 is closed and the supply of tap water is stopped. As the ejection of the washing water from the nozzle device 15 stops, the nozzle cue 21 moves backward to the storage position.

 [0219] Next, when the user performs a drying operation, power supply to the air blower and the heater of the drying device 120 is started. As a result, hot air is blown out toward the local area of the user. After the local drying, when the user performs an operation for finishing the drying, the drying device 120 stops.

 FIG. 34 is a perspective view showing a state where the sanitary washing device 10 is erected. When the drain valve 134 is used, as shown in FIG. 34, the entire sanitary washing device 10 is erected on the toilet and the drain valve 134 is opened and closed. At this time, since the drain valve 134 is disposed so as to face obliquely upward at a high position of the main body 12, operability and visibility are very good.

 [0221] (3-3) Effect of wash water tank 116

 In the washing water tank 116 described above, the joint surface 147 between the upper member 123 and the lower member 124 of the tank body 122 is formed diagonally. In this case, the pressure resistance strength of the cleaning water tank 116 can be maximized by the reinforcing edges 150 and 151. Further, since the opening areas of the upper member 123 and the lower member 124 are maximized, the upper member 123 and the lower member 124 can be easily molded. In particular, the reinforcing rib 145 can be easily and integrally formed on the inner surface of the lower member 124. Further, it is possible to easily perform the work of attaching the member such as the rectifying member 136 of the rectifying mechanism 135 to the tank body 122 with a large opening force.

 [0222] Further, a reinforcing rib 145 extending in the lateral direction is provided inside the back surface of the tank body 122.

 Thereby, the pressure resistance of the tank body 122 is improved. In addition, the stored washing water is prevented from convection more than necessary. As a result, the heated wash water is always stored in the upper part of the wash water tank 116. Since the reinforcing rib 145 is provided inside the tank main body 122, the necessary capacity can be ensured without increasing the outer dimensions of the tank main body 122. Therefore, a space-saving washing water tank 116 is realized.

[0223] Further, since the upper member 123 and the lower member 124 of the tank main body 122 are joined by welding, the joining portion does not protrude outward more than necessary. Thereby, further space saving of the washing water tank 116 is realized. [0224] The inner peripheral edges 148a and 149a of the opening edges 148 and 149 are subjected to stress that causes the joint between the upper member 123 and the lower member 124 to peel off due to the internal pressure of the washing water tank 116. As described above, the inner peripheral edges 148a and 149a of the opening edges 148 and 149 are welded over the entire circumference. As a result, the bonding strength of the inner peripheral edges 148a and 149a of the opening edges 148 and 149 can be ensured. Therefore, the pressure strength of the tank body 122 is improved.

 [0225] Furthermore, since the upper member 123 and the lower member 124 are fastened by the screws 170, the pressure resistance of the tank body 122 is further improved.

 [0226] Further, a rectifying mechanism 135 is provided continuously to the water inlet 127 of the tank body 122. As a result, the flow rate of the cleaning water flowing into the cleaning water tank 116 decreases. In addition, since the wash water flowing into the wash water tank 116 is discharged along the bottom surface 130, the generation of turbulent flow in the wash water tank 116 is suppressed. Therefore, warm water is stored in the upper part of the wash water tank 116, and cold water is stored in the lower part, and mixing of warm water and cold water is suppressed. As a result, the local area can be washed with the washing water having the optimum temperature, and the electric energy required for heating the washing water can be suppressed.

 [0227] (3-4) Variation of wash water tank 116

 In the washing water tank 116 described above, a metal wire 153 embedded in the inner peripheral groove 152a and the outer peripheral groove 152b of the opening edges 149, 150 for joining the upper member 123 and the lower member 124 of the tank body 122 is provided. This is not limited to this, but it is possible to use other welding methods such as the use of ultrasonic waves. A mechanical joining method using screw or screws may be used, or they may be used in combination.

[0228] Further, in the washing water tank 116 described above, the force that the reinforcing edges 150, 151 are provided on the entire circumference of the opening edges 149, 150 of the upper member 123 and the lower member 124 is not limited to this. Part of 151 may be removed. In particular, in the cleaning water tank 116 described above, even if the portions of the reinforcing edges 150 and 151 on the front surface or the back surface are removed, the influence on the pressure resistance of the cleaning water tank 116 is small. Further, a part of the reinforcing edges 150 and 151 on the side surface of the cleaning water tank 116 may be removed. For example, when interference between a part of the reinforcing edges 150 and 151 and another member occurs, the minimum part of the reinforcing edges 150 and 151 may be removed. Yes. In this case, the removed portions of the reinforcing edges 150 and 151 can be reinforced by other methods.

 [0229] Further, in the washing water tank 116 described above, the reinforcing edges 150 and 151 have a configuration projecting outward in consideration of moldability, but the reinforcing edge is not limited to this. The reinforcement edge that protrudes inwardly extends beyond both the inside and the outside of the tank body 122, or the reinforcement edge is thicker than the surface components such as the side or back of the tank body 122. You may form with the part which has.

 [0230] Further, in the washing water tank 116 described above, the force that only the laterally extending reinforcing rib 145 is formed on the inner surface of the rear portion of the lower member 124 is not limited to this, and the laterally extending reinforcing rib 145 is not limited to this. In addition, reinforcing ribs extending in the vertical direction may be provided. Thereby, the pressure strength is further improved. Further, reinforcing ribs may be formed inside the bottom surface 130 of the lower member 124 as necessary. Further, when it is necessary to reinforce the pressure resistance of the upper member 123, similar reinforcing ribs may be provided on the inner surface of the upper member 123.

 [0231] (3-5) Other examples of joints of tank body 122

 FIG. 35 is a cross-sectional view of the principal part showing another example of the joint portion of the tank main body 122.

 This example is different from the example of FIG. 33 in that the inner peripheral edges 17 la and 172a of the opening edges 148 and 149 are formed so as to protrude into the tank body 122 as shown in FIG. is there.

 [0233] An inner peripheral groove 152a is provided over the entire periphery of the opening edge 149 in the vicinity of the inner peripheral edge 172a, and an outer peripheral groove 152b is provided over the entire periphery of the opening edge 149. A metal wire 153 is embedded in the inner circumferential groove 152a and the outer circumferential groove 152b.

 [0234] The reinforcing edges 150 and 151 provided outside the opening edges 148 and 149 are sandwiched and fixed by a substantially U-shaped reinforcing member 176 made of metal.

 [0235] According to such a configuration, when pressure is applied to the inside of the tank body 122 by the washing water, in addition to the stress that separates the upper member 123 and the lower member 124, the opening edge 148, A force also acts in the direction in which the inner peripheral edges 171a and 172a of 149 are brought into close contact with each other. Thereby, the stress which peels off the upper member 123 and the lower member 124 can be reduced.

[0236] Further, by providing the reinforcing member 176 so as to sandwich the reinforcing edges 150 and 151, the joint between the upper member 123 and the lower member 124 can be mechanically fixed. Thereby, the upper member 1 The strength against peeling of 23 and lower member 124 is further improved. As a result, reliability and durability are improved.

 [0237] In this example, the configuration in which the inner peripheral edges 171a and 172a of the opening edges 148 and 149 protrude into the tank body 122 and the configuration in which the reinforcing member 176 is provided are used in combination. It is also possible to implement one of these configurations. For example, when one of these configurations is used in combination with the configuration of FIG. 33, an effective effect can be obtained.

 [0238] (3-6) Unit of cleaning water tank 116

 FIG. 36 is a perspective view of the tank unit including the cleaning water tank 116 and related parts, and FIG. 37 is a perspective view of the sanitary cleaning apparatus 10 inside the main body 12 during assembly.

 As shown in FIG. 36, a mounting piece 156 is formed by projecting a part of the reinforcing edge 150 of the tank body 122. By attaching the nozzle device 15 to the attachment piece 156 using the screw 157, the nozzle device 15 is integrated with the tank body 122. The inclination direction of the joint surface 147 of the tank body 122 is the same as the forward / backward direction (the direction of arrow B) of the nozzle unit 21 of the nozzle device 15. The on-off valve 118 and the water supply connection portion 117 are attached to the tank body 122. In this way, the tank unit 160 including the cleaning water tank 116, the water supply connecting portion 117, the on-off valve 118, and the nozzle device 15 is configured.

 [0240] Fig. 37 [As shown here, the bottom gate 12b of the main body 12, the tank unit 160, the drying device 120, the deodorizing device 162, the toilet seat toilet lid opening and closing device 163 and the support member 165 are individually fixed with screws or the like. The

 [0241] The tank unit 160 includes all the water-circulating members that serve as the cleaning water path of the sanitary cleaning device 10. Therefore, it is possible to perform a water leak inspection and an inspection of each function at the stage of assembling the tank unit 160. Therefore, it is not necessary to handle the entire sanitary washing device 10 having a large size at the time of inspection. Thus, the handleability at the time of inspection improves. Further, since an abnormality can be found in the assembly stage of the tank unit 160, the repair work is facilitated.

 [0242] Further, since the joint surface 147 of the tank main body 122 and the forward / backward direction of the nozzle unit 21 indicated by the arrow B are the same, the long range of the nozzle device 15 can be stably fixed to the tank main body 122. .

[0243] (4) Seating detection switch (4-1) Configuration of seating detection switch 200

 FIG. 38 is a cross-sectional view of the seating detection switch 200. (a) shows a state where the user is not seated on the toilet seat 13, and (b) shows a state where the user is seated on the toilet seat 13.

 As shown in FIGS. 38 (a) and 38 (b), a cylindrical rotating shaft 218 having a metal force is provided on the side of the rear end of the toilet seat 13 so as to protrude inward. The side surface of the main body 12 of the sanitary washing device 10 is molded from a resin material. A long hole 219 extending in the vertical direction is formed on the side surface of the main body 12. A rotation shaft 218 of the toilet seat 13 passes through the long hole 219. Inside the main body 12, a switch base 220 formed of a resin material is fixed so as to face the long hole 219.

 [0245] Movable element 222 molded with resin is attached along sliding receiving portion 221 of switch base 220 so as to be slidable in the vertical direction. The mover 222 has a horizontal bearing hole 223. The rotating shaft 218 of the toilet seat 13 is inserted into the bearing hole 223 of the movable element 222. Accordingly, the toilet seat 13 is rotatable with respect to the main body 12 by the rotation shaft 218 and the bearing hole 223.

 A metal coil spring 224 is attached between the lower end portion 222 a of the mover 222 and the bottom portion 221 a of the sliding receiving portion 221. The coil spring 224 biases the mover 222 upward against the weight of the mover 222 and the toilet seat 13. A micro switch 225 is attached to the upper part of the switch base 220. The upper end of the mover 222 biased by the coil spring 224 pushes the movable piece 226 of the microswitch 225. The microswitch 225 has a normally closed type contact structure in which the contact is opened when the movable piece 226 is pressed and the contact is closed when the movable piece 226 is not pressed.

 When the user is not seated on the toilet seat 13, as shown in FIG. 38 (a), the mover 222 is urged upward by the coil spring 224, and the upper end of the mover 222 is the microswitch 22. Press the movable piece 226 of 5. In this state, the contacts of the microswitch 225 are open.

 The lead wire 217 connected to the toilet seat heater and the thermistor in the toilet seat 13 is inserted into the through hole of the rotating shaft 218. Lead wire 217 is connected to controller 700.

[0249] When the user is seated on the toilet seat 13, the weight of the user is added to the toilet seat 13. As a result, as shown in FIG. 38 (b), the rotating shaft 218 and the movable element 222 are pushed downward, and the upper end of the movable element 222 is separated from the movable piece 226 of the microswitch 225. In this state, the contact of the microswitch 225 is closed. In this state, the mover 22 A gap of 4 mm or more is formed between the upper end of 2 and the movable piece 226 of the microswitch 225.

 [0250] (4-2) Operation and action of seating detection switch 200

 Next, the operation and action of the seating detection switch 200 will be described.

 [0251] In the sanitary washing device 10 in the standby state, the control device 700 supplies power to the toilet seat heater of the toilet seat 13, and the seating surface of the toilet seat 13 is maintained at a comfortable temperature. Further, the cleaning water ejected from the nozzle device 15 at the time of local cleaning is heated in advance to an optimum temperature for cleaning and stored in the cleaning water tank 116.

 [0252] When the boys' small use is used, the toilet seat 13 and the toilet lid 14 are opened upward. In this case, the seating detection switch 200 is in the state shown in FIG. 38 (a), and the microswitch 225 is in the open state. As a result, a non-detection signal indicating that seating is not detected is sent from the microswitch 225 to the control device 700. That is, a detection signal indicating detection of seating is not sent from the microswitch 225 to the control device 700. The control device 700 determines that the user is not seated on the toilet seat 13 based on the non-detection signal of the microswitch 225 force. In this state, even if the user operates the operation unit 11 or the remote controller 40 by mistake, the control device 700 does not output the operation command for the nozzle device 15. For example, even if the user performs a local cleaning operation, the cleaning water does not spout from the nozzle device 15. Further, even when the user performs a drying operation, the drying device 120 does not start to operate similarly to the nozzle device 15.

 [0253] Next, when using the stool or the girl's elementary school, the user inverts the toilet seat 13 on the upper surface of the toilet and sits on the seating surface of the toilet seat 13. At this time, the seating surface of the toilet seat 13 is previously kept at a comfortable temperature. As a result, the user can comfortably sit on the toilet seat 13 even in cold weather.

When the user sits on the toilet seat 13, the weight of the user is added to the toilet seat 13. As a result, a downward force is applied to the rotation shaft 218 of the toilet seat 13 and the movable element 222 is pushed down against the biasing force of the coil spring 224. Therefore, as shown in FIG. 38 (b), the upper end of the movable element 222 is separated from the movable piece 226 of the micro switch 225, and a gap is formed between the upper end of the movable element 222 and the movable piece 226 of the micro switch 225. It is formed. At this time, the contact point of the microswitch 225 is closed, and a detection signal indicating detection of seating is sent to the control device 700. [0255] In the state where the seating is detected, when the user performs the local cleaning operation, the nozzle unit 21 of the nozzle device 15 advances to the cleaning position, and the bottom butt cleaning outlet 31 or the bidet cleaning jet Wash water is spouted from outlet 32. Thereby, local cleaning is performed. In addition, when the user performs the cleaning end operation, the nozzle unit 21 moves back to the original storage position, and the cleaning operation ends.

 [0256] Subsequently, when the user performs a drying operation, the control device 700 energizes the air blower and the heater of the drying device 120. As a result, the hot air blows out toward the local area of the hot air blowing roller user, and the wet local area is dried by washing. When the user completes the drying operation, the drying device 120 stops and the drying operation ends.

 [0257] When the user stands up during the local washing or drying operation, the weight of the user who is added to the toilet seat 13 is released, so that the rotating shaft 218 and the mover 222 are moved upward by the biasing force of the coil spring 224. Move to, and press the movable piece 226 of the microswitch 225. As a result, the contact point of the micro switch 225 is opened, and a non-detection signal indicating that the user is not seated is sent from the micro switch 225 to the control device 700. In this case, the controller 700 immediately stops the local cleaning or drying operation. Therefore, it is possible to prevent the washing water from spraying around the toilet and wetting the user's clothes or the floor and walls in the toilet room, and the hot air from being blown out unnecessarily.

 [0258] The user often powers and moves the body while sitting on the toilet seat 13. In the seating detection switch 200 of this example, a clearance of 4 mm or more is provided between the upper end of the movable element 222 and the movable piece 226 of the microswitch 225 in the seated state. Therefore, the movable piece 226 of the microswitch 225 is pushed by the upper end of the mover 222 even if the rotating shaft 218 of the toilet seat 13 moves slightly by powering or moving the body while the user is seated. There is no. Therefore, the local cleaning and drying operations are prevented from stopping against the user's intention.

 [0259] (4 3) Effect of seating detection switch 200

As described above, in the seating detection switch 200 of the present example, the microswitch 225 is arranged on the upper part of the rotating shaft 218 of the toilet seat 13, and the movable piece 226 is moved by the upper end of the movable element 22 2 by the biasing force of the coil spring 224. Pressed. As a result, the user's weight is directly applied to the microswitch 225. There is no participation. Further, the microswitch 225 is not applied with a force greater than the urging force of the coil spring 224. As a result, breakage and durability of the microswitch 225 are prevented from decreasing.

 [0260] Further, a gap of 4 mm or more is provided between the upper end of the movable element 222 and the movable piece 2226 of the microswitch 225 in the seated state. Thereby, even if the user slightly moves or moves his / her body while sitting, the malfunction of the sanitary washing device 10 being stopped against the user's intention is avoided.

 [0261] When the user is not seated on the toilet seat 13, the microswitch 225 is in an open state, and no current flows in the circuit. Therefore, power saving can be achieved.

 [0262] (4 4) Modification of seating detection switch 200

 In the seating detection switch 200 described above, a force that uses a metal coil spring 224 as an elastic body that biases the mover 222 upward is not limited to this. Alternatively, an elastic body other than a metal, such as rubber or rubber or elastic resin may be used. In particular, since water is used in the sanitary washing device 10, it is desirable to use a material having corrosion resistance as the elastic body.

 [0263] In the seating detection switch 200 described above, the clearance formed between the upper end of the movable element 222 and the movable piece 226 of the micro switch 225 is set to 4 mm or more in consideration of certainty. Force to be applied Not limited to this, the minimum gap less than 4mm is provided, and a corresponding effect can be obtained.

 [0264] (5) Earth leakage breaker

 (5-1) Operation section 11

 FIG. 39 is a plan view showing details of the operation unit 11 of FIG. As shown in FIG. 39, a plurality of switches 306 and a plurality of display lamps 307 used for operating various functions of the sanitary washing device 10 or setting various functions are provided on the upper surface of the operation unit 11. .

 [0265] In addition, on the upper surface of the operation unit 11, an earth leakage display LED (light emitting diode) 322, which is an earth leakage display unit, and a test switch 323 used for testing the earth leakage breaker 300 are provided. The test switch 323 also has a push switch force.

[0266] The test switch 323 is disposed at the rear end of the operation unit 11, and the test switch 323 is provided. The pressing area is small. This can prevent the user from operating the test switch 323 by mistake. Further, the pressing force required for operating the test switch 323 is set to 3 to 5 times the pressing force required for operating the other switch 306. As a result, even if the user touches the test switch 323 to clean the operation unit 11 or the like, erroneous operation does not easily occur.

 [0267] (5-2) First example of circuit configuration of sanitary washing device 10

 FIG. 40 is a circuit diagram showing a first example of the circuit configuration of the sanitary washing device 10.

 [0268] The power plug 309 is connected to the power outlet 308. A pair of power lines 310 is connected to the power plug 309. The power supply line 310 is connected to the power supply circuit 312 through a ZCT (Zero Phase Current Transformer) 311 that detects the difference between the reciprocating currents. The power supply circuit 312 generates a DC power supply voltage and applies the DC power supply voltage to the control device 700, the deodorizing device 162, the toilet seat toilet lid opening / closing device 163, and the like.

 [0269] The control device 700 controls the overall operation of the sanitary washing device 10. Specifically, the control device 700 controls the deodorizing device 162 and the toilet seat toilet lid opening / closing device 163, and also controls the triacs 318 and 319 for turning on and off the hot water heater 131 and the toilet seat heater 580. The control device 700 drives the drive motor 44 (FIGS. 14 to 16), the flow rate adjusting valve 61 (FIGS. 3 to 5), and the drying device 120 (FIG. 26) of the nozzle device 15.

 [0270] The output voltage of ZCT311 is applied to leakage detection circuit 320. The leakage detection circuit 320 controls the leakage breaker relay 321 having three contacts 321a, 321b, and 321c. One power supply line 310 is connected to the contact 321a, and the other power supply line 310 is connected to the contact 321b. The output terminal of the power supply circuit 312 is connected to the contact 321c.

 [0271] The contacts 321a, 321b, and 321c are normally connected to terminals 321e, 321f, and 321g, respectively. The terminal 321e is connected to the hot water heater 131 and the toilet seat heater 580. The terminal 321f is connected to one power supply terminal of the control device 700 and the triacs 318 and 319. Terminal 32 lg is connected to the other power terminal of controller 700.

 [0272] A test current line 324 is passed through the ZCT 311. Between the terminal 321d and the test current line 324, a leakage indicator LED 322 and a test switch 323 are connected.

[0273] ZCT311, Earth leakage detection circuit 320, Relay 321, Earth leakage indicator LED322, Test switch 3 23 and test current line 324 constitute earth leakage breaker 300.

 [0274] (5-3) Operation and action of sanitary washing device 10

 The operation and action of the sanitary washing device 10 of FIG. 40 will be described.

 [0275] When an electrical leakage occurs in the sanitary washing device 10, an output voltage is generated in the ZCT 311 due to a difference in the reciprocating current of the power line 310. Thereby, the leakage detection circuit 320 controls the relay 321 for cutting off the leakage and opens the contacts 321b and 321c. As a result, the hot water heater 131, the toilet seat heater 580, and the control device 700 are disconnected from the power supply line 310 and the power supply circuit 312. In addition, leakage detection circuit 320 switches contact 321a of relay 321 to terminal 321d. As a result, a current flows from one power line 310 to the other power line 310 through the leakage indicator LED 322, and the leakage indicator LED 322 is lit. Therefore, the user can recognize that the sanitary washing device 10 is leaking electricity.

 On the other hand, if the user presses the test switch 323 while the leakage indicator LED 322 is lit, a current flows through the test current line 324 passed through the ZCT 311. As a result, an output voltage is generated in ZCT 311 as in the case where a difference occurs in the reciprocating current of power supply line 310, and relay 321 is operated in the same manner as when a leakage occurs. In this case as well, the earth leakage indicator LED322 is lit, so the user can confirm that the earth leakage breaker 300 operates normally.

 [0277] At this time, for example, when the ZCT 311 is damaged or the leakage detection circuit 320 is disconnected, the leakage indicator LED 322 does not light up. Therefore, the user can recognize that the earth leakage breaker 300 is abnormal.

[5278] (5-4) Second example of circuit configuration of sanitary washing device 10

 FIG. 41 is a circuit diagram showing a second example of the circuit configuration of the sanitary washing device 10. In the circuit configuration of FIG. 41, the same parts as those of FIG.

[0279] The second example of the sanitary washing device 10 differs from the first example in that a power circuit 332 including an isolation transformer is used instead of the power circuit 312 and two contacts 333a, 333 are used instead of the relay 321. A relay 333 having b is used.

One power line 310 is connected to the contact 333a, and the other power line 310 is connected to the contact 333b. Contacts 333a and 333b are normally connected to terminals 333d and 333e, respectively. The

 Terminal 333d is connected to warm water heater 131 and toilet seat heater 580. The terminal 333e is connected to one power supply terminal of the control device 700 and the triacs 318 and 319. A leakage indicator LED 322 is connected between the terminal 333c and the other power supply line 310, and a test switch 323 is connected between one output terminal of the power supply circuit 332 and the test current line 324. The other output terminal of power supply circuit 332 is connected to the other power supply terminal of control device 700.

 [0282] ZCT 311, leakage detection circuit 320, relay 333, leakage indicator LED 322, test switch 323 and test current line 324 constitute leakage breaker 300.

 [0283] When there is no leakage in the sanitary washing device 10, electric power is supplied to the hot water heater 131, the toilet seat heater 580, and the control device 700 from the power line 310 and the power circuit 332 by the relay 333.

 [0284] When a leakage occurs in the sanitary washing device 10, an output voltage is generated in the ZCT 311 as in the first example. Thereby, leakage detection circuit 320 controls relay 333 and opens contact 333b. As a result, the hot water heater 131 and the toilet seat heater 580 are cut off from the power line 310 and the power circuit 332. At this time, power is supplied to the control device 700 in a state where it is insulated from the power supply line 310 by the power supply circuit 332 having an insulating transformer force. Therefore, the deodorizing device 162 and the toilet seat toilet lid opening / closing device 163 driven by the force control device 700 that stops the hot water heater 131 and the toilet seat heater 580 can operate. Therefore, even when electric leakage occurs, the toilet seat 13 and the toilet lid 14 that are necessary for the toilet can be opened and closed, and the user can use the minimum toilet function.

 [0285] Similarly to the first example, leakage detection circuit 320 switches contact 333a of relay 333 to terminal 333c. As a result, a current flows from one power line 310 to the other power line 310 through the leakage indicator LED 322, and the leakage indicator LED 322 is lit. Therefore, the user can recognize that the sanitary washing device 10 is leaking electricity.

 [0286] Similarly to the first example, when the user presses the test switch 323, it can be confirmed that the earth leakage breaker 300 operates normally.

[0287] (5-5) Third example of circuit configuration of sanitary washing device 10 FIG. 42 is a front view of the remote control. FIG. 43 is a circuit diagram showing a third example of the circuit configuration of the sanitary washing device 10. In the circuit configuration of FIG. 43, the same components as those of FIG.

 [0288] The remote controller 40 of Fig. 42 is used by being installed on the wall surface of the toilet, etc., separately from the operation unit 11 provided integrally with the main body 12. Two-way communication using infrared rays is performed between the remote control 40 and the main body 12 of the sanitary washing device 10.

 [0289] On the front surface of the remote controller 40, similarly to the operation unit 11, a plurality of switches 403 and a plurality of display units 404 used for operating each function of the sanitary washing device 10 or setting each function are provided. Provided. At the lower end of the front surface of the remote control 40, a leakage indicator 405 and a test switch 406 used for testing the leakage breaker 300 are provided.

 [0290] The pressing area of the test switch 406 is formed small. Further, the pressing force required for operating the test switch 406 is set to 3 to 5 times the pressing force required for operating the other switch 403. Thereby, erroneous operation of the test switch 406 is prevented.

 [0291] Fig. 43 [As shown in the figure, including remote control = 40 °, remote control = 3 ° U control 402, remote power supply 407, and remote control communication unit 408. The remote control power supply unit 407 is made of a battery. The remote control unit 402 and the remote control communication unit 408 operate with the power supplied from the remote control power supply unit 407.

 [0292] The third example of the sanitary washing device 10 is different from the second example in that it further includes a communication unit 409, a short circuit 410, and a zero-cross detection circuit 411.

 [0293] The communication unit 409 performs bidirectional communication with the remote control 40 using infrared rays. The short circuit 410 generates a leakage state by a test signal from the remote control 40. The zero cross detection circuit 411 detects that the relay 333 is activated and the hot water heater 131 and the toilet seat heater 580 are cut off from the power line 310.

[0294] When a leak occurs in the sanitary washing device 10, an output voltage is generated in the ZCT 311 as in the second example. Thereby, leakage detection circuit 320 controls relay 333 and opens contact 333b. As a result, the hot water heater 131 and the toilet seat heater 580 are cut off from the power line 310 and the power circuit 332. At this time, power is supplied to the control device 700 in a state where it is insulated from the power supply line 310 by the power supply circuit 332 having an insulating transformer force. Therefore, the hot water heater 131 and the toilet seat heater 580 are driven by the stopping force control device 700. The deodorizing device 162 and the toilet seat toilet lid opening / closing device 163 can operate.

 [0295] Similarly to the second example, leakage detection circuit 320 switches contact 333a of relay 333 to terminal 333c. As a result, a current flows from one power line 310 to the other power line 310 through the leakage indicator LED 322, and the leakage indicator LED 322 is lit. Therefore, the user can recognize that the sanitary washing device 10 is leaking electricity.

 [0296] Further, when the zero-cross detection circuit 411 detects that the power supply from the power supply line 310 is cut off, the zero-cross detection circuit 411 gives a detection signal to the control device 700. The control device 700 provides the communication unit 409 with a lighting signal for lighting the electric leakage display unit 405 of the remote controller 40. Thereby, the communication unit 409 transmits a lighting signal to the remote control communication unit 408 by infrared rays. The remote control communication unit 408 of the remote control 40 gives the received lighting signal to the remote control control unit 402. As a result, the remote control unit 402 turns on the leakage indicator 405.

 On the other hand, when the user presses test switch 406 of remote controller 40, remote controller control unit 402 provides a test signal to remote controller communication unit 408. The remote control communication unit 408 transmits a test signal to the communication unit 409 of the main body 12. The communication unit 409 gives the received test signal to the control device 700. Thereby, the control device 700 brings the short circuit 410 into a connected state. As a result, a leakage condition occurs and the leakage breaker 300 is tested.

 [0298] In addition, as in the first and second examples, the user can confirm that the earth leakage breaker 300 operates normally by pressing the test switch 323 of the operation unit 11.

 [0299] In both cases of the above-mentioned remote control 40 and earth leakage circuit breaker 300 test using operation unit 12, both earth leakage display LED 322 of operation unit 11 and earth leakage display unit 405 of remote control 40 are lit.

 [0300] In the third example, a leakage indicator 405 and a test switch 406 are provided on the remote controller 40 that is normally installed at a position that is easy for the user to operate. As a result, the user can easily see the abnormality of the sanitary washing device 10 and the usability of the sanitary washing device 10 is improved.

[0301] In this example, infrared communication is performed between the main body 12 and the remote control 40. However, the communication method is not limited to this, and wireless communication using radio waves, or You can use wired electrical signals! [0302] In addition, in this example, the remote control 40 is provided with the earth leakage display unit 405 and the test switch 406, and the operation unit 11 is provided with the earth leakage display LED 322 and the test switch 323. 1S The remote control is not limited to this. Only 40 is provided with the leakage indicator 405 and the test switch 406, and the leakage indicator LED 322 and the test switch 323 may not be provided on the operation unit 11.

 [0303] (6) Toilet seat

 (6-1) Structure of toilet seat 13

 44 is an exploded perspective view of the toilet seat 13, FIG. 45 is a view of the upper toilet seat casing also viewed from the lower side, FIG. 46 is a view of the lower toilet seat casing viewed from the upper side, and FIG. 47 is the upper toilet seat on the U-U line of FIG. It is an expanded sectional view of a casing.

 [0304] As shown in FIG. 44, the toilet seat 13 has a substantially annular shape, and includes an upper toilet seat casing 510 formed of aluminum and a lower toilet seat casing 520 formed of synthetic resin.

 [0305] As indicated by the alternate long and short dash line, a part of the upper surface of the upper toilet seat casing 510 is the seating portion of the user.

 510T.

 As shown in FIG. 44 and FIG. 45, two thermistors 511 are attached to the lower surface side of the upper toilet seat casing 510 in the region of the seating part 510T. In addition, two thermistors 512 are installed in other areas.

 [0307] Note that one thermistor 511 may be provided in the region of the seating portion 510T. One thermistor 512 may be provided in other areas.

 As shown in FIGS. 44 and 46, on the upper surface side of the lower toilet seat casing 520, a radiation reflecting plate 530 formed so as to follow the shape of the lower toilet seat casing 520 is attached. The radiation reflector 530 is manufactured by mirror-finishing the surface of a plate material made of aluminum.

 [0309] Further, a toilet seat heater 580 is provided on the upper surface of the radiation reflecting plate 530. The toilet seat heater 580 is manufactured by connecting a rear lamp heater 581 and a front lamp heater 582 formed in a U shape in series.

[0310] Further, on the upper surface of the radiation reflector 530, there are predetermined locations (two locations) of the front lamp heater 582. Two thermostats 541 are attached so as to be close to each other, and two thermostats 542 are attached so as to be close to predetermined places (two places) of the rear lamp heater 581. The plurality of thermostats 541 and 542 are both connected in series to the toilet seat heater 580.

 [0311] The toilet seat 13 is completed by joining the upper toilet seat casing 510 of Fig. 45 and the lower toilet seat casing 520 of Fig. 46 via a sealing material (not shown). As a result, the spaces in the upper toilet seat casing 510 and the lower toilet seat casing 520 are sealed. The see-through material prevents water from entering the upper toilet seat casing 510 and the lower toilet seat casing 520. In this state, the thermistor 511 attached to the upper toilet seat casing 510 faces the front lamp heater 582.

 [0312] The rear lamp heater 581 and the front lamp heater 582 are halogen lamp heaters.

 In the halogen lamp heater, a filament is provided inside a glass tube and an argon gas and a halogen gas are enclosed.

 As shown in FIG. 47, the upper toilet seat casing 510 is produced by forming various layers on the upper and lower surfaces of the aluminum layer 510b having excellent thermal conductivity. The thermal conductivity of aluminum is about 237WZm'K.

 [0314] A black paint containing carbon or the like is applied to the lower surface of the aluminum layer 510b. As a result, a black radiation absorbing layer 510a capable of efficiently absorbing radiation energy is formed on the lower surface of the aluminum layer 510b.

 [0315] On the upper surface of the aluminum layer 510b, an alumite layer 510c and a surface decorative layer 510d are sequentially formed. By forming the alumite layer 510c, the corrosion resistance of the upper surface of the aluminum layer 510b is improved. The surface decorative layer 510d is formed of a predetermined paint or the like.

 [0316] The thermistor 511 is attached to the lower surface of the aluminum layer 510b via the radiation absorbing layer 510a. The thermistor 511 detects the temperature of the aluminum layer 510b through the radiation absorbing layer 510a.

 [0317] Toilet seat heater 580, thermistors 511, 512 and thermostats 541, 542 are control devices 7

Connected to 00.

[0318] (6-2) Structure of toilet seat heater 580

The rated power of rear lamp heater 581 and front lamp heater 582 in this example is Set to 500W and 700W. In this case, the rated power of the toilet seat heater 580 is 1200W.

 [0319] Here, the length of the rear lamp heater 581 is 460 mm, and the length of the front lamp heater 582 is 600 mm. In this case, the rated power per unit length of the rear lamp heater 581 is about 1087 WZm, and the rated power per unit length of the front lamp heater 582 is about 1167 WZm.

 In this way, the rated power per unit length of the front lamp heater 582 is set to be larger than the rated power per unit length of the rear lamp heater 581. Thereby, the magnitude per unit length of the radiant energy generated from the front lamp heater 582 can be made larger than the magnitude per unit length of the radiant energy generated from the rear lamp heater 581.

 [0321] Therefore, when the toilet seat heater 580 of this example is driven, the seat 510T force positioned in front of the upper toilet seat casing 510 is heated by receiving radiation energy larger than the rear portion of the upper toilet seat casing 510, and the seat The temperature of 510T can be increased rapidly compared to other parts. As a result, the seating portion 510T is preferentially heated, so that the user is prevented from feeling cold when sitting on the seating portion 510T.

 [0322] In this example, the power toilet heater 580 explained that the rear lamp heater 581 and the front lamp heater 582 with different rated power are used. The toilet seat heater 580 is composed of three or more lamp heaters with different rated power. Also good.

 In this case, by adjusting the arrangement of the plurality of lamp heaters with respect to the upper toilet seat casing 510, the magnitude of the radiant energy given to each part of the upper toilet seat casing 510 can be adjusted more delicately. This sufficiently prevents the user from feeling cold when sitting on the seat 510T.

 [0324] (6-3) Shape of upper toilet seat casing 510

 As shown in FIG. 45, the size (area) of the upper toilet seat casing 510 of this example differs between the front part FA and the rear part B A. In this example, the width FW of the upper toilet seat casing 510 of the front portion FA is about 50 mm, while the width BW of the rear portion is about 100 mm.

[0325] In this case, all of the radiant energy generated by the toilet seat heater 580 is transferred to the upper toilet seat case. If it is given to the sing 510, the magnitude of the radiant energy given per unit length of the upper toilet seat casing 510 (the length along the ring shape) varies depending on the portion of the upper toilet seat casing 510.

 [0326] In this example, the magnitude per unit time of the radiant energy given per unit length in the front part FA of the upper toilet seat casing 510 is equal to the width radiant energy given per unit length in the rear part BA. It is about twice the size per unit time.

 [0327] Thereby, as the toilet seat heater 580 starts to be driven, the temperature of the upper toilet seat casing 510 can be rapidly increased as compared with other portions. As a result, the seating portion 510T is preferentially heated, so that the user can be prevented from feeling cold when sitting on the seating portion 510T.

 [0328] Thus, by adjusting the shape of the upper toilet seat casing 510, the degree of temperature rise during the operation of the toilet seat heater 580 (temperature increase rate) can be adjusted for each portion of the upper toilet seat casing 510. .

 [0329] (6-4) Relationship between toilet seat heater 580 and upper toilet seat casing 510

 Accordingly, by adjusting the combination of the configuration of the toilet seat heater 580 and the shape of the upper toilet seat casing 510, the temperature increase rate of the upper toilet seat casing 510 when the toilet seat heater 580 is driven can be increased for each portion of the upper toilet seat casing 510. Can be adjusted in detail.

 [0330] As shown in this example, a front lamp heater 582 having a large radiation energy generated per unit length is arranged in front of the upper toilet seat casing 510, and the front portion FA of the upper toilet seat casing 510 is larger. By designing the height to be small, the heating rate of the seating portion 510T can be sufficiently improved.

 [0331] Even if the arrangement position of the toilet seat heater 580 in the upper toilet seat casing 510 is adjusted, a desired temperature distribution can be formed in the upper toilet seat casing 510 at the time of temperature rise.

[0332] For example, in the front part FA of the upper toilet seat casing 510, the toilet seat heater 580 is brought close to the inner surface of the upper toilet seat casing 510, and in the rear part BA, the toilet seat heater 580 is also placed at an inner surface force of the upper toilet seat casing 510 at a predetermined interval. Separate. Even in this case, the heating rate of the front part FA of the upper toilet seat casing 510 is made larger than that of the rear part BA. be able to.

 [0333] Furthermore, the thickness of the material may be changed in each portion of the upper toilet seat casing 510.

 For example, the thickness of the front portion FA of the upper toilet seat casing 510 is set thin, and the thickness of the rear portion BA is set thick. Even in this case, the same effect as described above can be obtained.

 [0334] Also, the material of each part of the upper toilet seat casing 510 may be changed. For example, a material with high thermal conductivity is used for the front portion FA of the upper toilet seat casing 510, and a material with low thermal conductivity is used for the rear portion BA. Even in this case, the same effect as described above can be obtained.

 [0335] (6-5) Toilet seat heater 580 drive

 As described above, the rear lamp heater 581 and the front lamp heater 582 are connected to the control device 700 via the triac 319 of FIG. 40, FIG. 41, or FIG. Triac 31

When a current flows through the rear lamp heater 581 and the front lamp heater 582 due to 9, the infrared rays are radiated from the lamp heaters to the surroundings.

Then, infrared rays radiated from the rear lamp heater 581 and the front lamp heater 582, that is, radiant energy, directly or indirectly enter the lower surface side of the upper toilet seat casing 510 via the radiation reflector 530.

[0337] As described above, the black radiation absorbing layer 510a (Fig. 47) can efficiently absorb the radiation energy, so that the radiation energy from the rear lamp heater 581 and the front lamp heater 582 is efficiently aluminum. Delivered to layer 510b (Figure 47). As a result, the aluminum layer 510b generates heat.

[0338] As described above, since aluminum has high thermal conductivity, heat generated by radiant energy is transmitted to the entire upper toilet seat casing 510 in a short time.

[0339] Thus, when the temperature of the upper toilet seat casing 510 rises due to the driving of the toilet seat heater 580, even if the temperature unevenness occurs in the upper toilet seat casing 510, the temperature of the upper toilet seat casing 510 is equalized in a short time. The

[0340] (6-6) Example of driving toilet seat heater 580

The driving of the toilet seat heater 580 is controlled by changing the electric power for driving the toilet seat heater 580 into three. [0341] For example, when the temperature of the toilet seat 13 is raised at a first temperature gradient, the control device 700 drives the toilet seat heater 580 with a power of about 1200W (1200W drive). When the temperature of the toilet seat 13 is raised at a second temperature gradient that is slightly gentler than the first temperature gradient, the control device 700 drives the toilet seat heater 580 with about 600 W of electric power (600 W drive). Furthermore, when the temperature of the toilet seat 13 is kept constant, the control device 700 drives the toilet seat heater 580 with a power of about 50 W (low power drive). The low power drive means that the toilet seat heater 580 is driven by a sufficiently low power (for example, power in the range of 0 W to 50 W) compared to the 1200 W drive and the 600 W drive.

[0342] Switching between 1200 W drive, 600 W drive, and low power drive is performed by the control device 700 controlling the energization rate by the triac 319 (Figs. 40, 41, and 43).

 FIG. 48 is a diagram showing a driving example of the toilet seat heater 580 and a change in the surface temperature of the seating portion 510T (FIGS. 44 and 45).

 [0344] FIG. 48 shows a graph showing the relationship between the surface temperature of seating portion 510T and time, and a graph showing the relationship between the energization rate and time when driving toilet seat heater 580. . The horizontal axis of these two graphs is a common time axis.

 In this example, it is assumed that the user has set the toilet seat set temperature high (38 ° C) in advance.

 [0346] When the room temperature is lower than the standby temperature of 18 ° C, such as in winter, the control device 700 (Fig. 2) adjusts the temperature of the toilet seat 13 to 18 ° C. In this way, the control device 700 controls the toilet seat heater so that the surface temperature of the seating portion 510T is constant at 18 ° C. during the waiting period D1 until the entrance of the user is detected by the entrance sensor 600. 580 low power drive.

 [0347] When the entry sensor 600 detects that the user has entered the room at time tl, the control device 700 drives the toilet seat heater 580 at 600 W during the inrush current reduction period D2. This 600 W drive is performed in order to sufficiently reduce the inrush current. In this case, the surface temperature of the seating portion 510T is raised with a slightly gentle second temperature gradient.

[0348] After that, at time t2 after the rush current reduction period D2 elapses, the control device 700 starts 1200 W drive of the toilet seat heater 580, and performs 1200 W drive of the toilet seat heater 580 during the first temperature rising period D3. continue. In this case, the surface temperature of the seating portion 510T is increased with the first temperature gradient described above. [0349] Here, the surface temperature of the seating portion 510T is rapidly increased. The toilet seat heater 580 is driven at 1200W until the surface temperature of the seat 510T reaches the limit temperature. The critical temperature is that the user feels cold! /, The minimum temperature of the seating part 510T.

 [0350] In the graph showing the surface temperature of the seating portion 510T in FIG. 48, the limit temperature is 29 ° C, which is indicated by a one-dot chain line. When the toilet seat heater 580 is driven at 1200W, the measured temperature value assumed when the surface temperature of the seating section 510T reaches the limit temperature is the switching temperature.

 [0351] The time t3 when the surface temperature of the seating portion 510T reaches the limit temperature is the 1200 W drive time determined by the heater control table and the time until the measured temperature value reaches the predetermined switching temperature. Short, time.

 Thus, in the first temperature raising period D3, the surface temperature of the seating portion 510T is rapidly raised to the limit temperature by 1200W driving. Thus, the user can sit on the toilet seat 13 without feeling that the seating portion 510T is cooled.

 [0353] Further, as described above, when the surface temperature of the seating portion 510T is rapidly increased, an overshoot occurs in the temperature change. However, in this example, when the surface temperature of the seating portion 510T reaches the limit temperature, the toilet seat heater 580 is switched from 1200 W driving to 600 W driving. Therefore, even when the change in the surface temperature of the seating portion 510T overshoots, the surface temperature does not exceed the toilet seat set temperature. As a result, the user is prevented from feeling that the seating portion 510T is hot when seated.

 [0354] Subsequently, at time t3 after the elapse of the first temperature rising period D3, the control device 700 starts driving the toilet seat heater 580 at 600 W, and the toilet seat heater 580 is turned on during the second temperature rising period D4. Continue 600W drive. In this case, the surface temperature of the seating portion 510T is raised by the second temperature gradient described above.

[0355] The 600 W drive of the toilet seat heater 580 is performed until the surface temperature of the seating section 510T reaches a temperature (40 ° C) slightly higher than the toilet seat set temperature. Here, when the toilet seat heater 580 is driven at 600 W, the measured temperature value that is assumed when the surface temperature of the seating portion 510T is slightly higher than the toilet seat set temperature is the predetermined target temperature.

[0356] The time t4 when the surface temperature of the seating portion 510T reaches a temperature slightly higher than the toilet seat set temperature is a predetermined 600 W drive time and a target temperature at which a measured temperature value is predetermined. This is the shortest time to reach.

 [0357] The second temperature gradient is gentler than the first temperature gradient. This prevents a large overshoot from occurring in the change in the surface temperature of the seating portion 510T.

 [0358] Control device 700 starts low-power driving of toilet seat heater 580 at time t4 after the elapse of second temperature rising period D4, and low-power driving of toilet seat heater 580 during first maintenance period D5. Continue. As a result, the surface temperature of the seating portion 510T becomes constant at a temperature slightly higher than the toilet seat set temperature.

 [0359] In this example, the surface temperature of the seating part 510T is raised to a temperature slightly higher than the toilet seat set temperature set by the user, and this temperature is maintained until the user is seated. Therefore, the user can obtain a temperature that is almost the same as the temperature set by the user when the user is seated.

 [0360] When the seating detection switch 200 detects the seating of the user on the toilet seat 13 at time t5, the control device 700 reduces the current-carrying rate of the low-power drive, and the seating portion during the first seating period D6. The low-power drive of the toilet seat heater 580 is continued so that the surface temperature of 510T falls to the toilet seat set temperature. In this example, the first sitting period D6 is set to about 2 minutes.

 [0361] In addition, at time t6 after the lapse of the first seating period D6, the control device 700 further reduces the energization rate of the low power drive, and the surface temperature of the seating part 510T is increased during the second seating period D7. Toilet seat heater 580 continues to be driven at low power so that it is slightly lower than the set temperature of the toilet seat and drops to a temperature (36 ° C). In this example, the second sitting period D7 is set to about 2 minutes.

 [0362] At time t7 after the elapse of the second seating period D7, the control device 700 further reduces the energization rate of the low power drive, and the surface temperature of the seating part 510T is set to the toilet seat during the second maintenance period D8. The low-power drive of the toilet seat heater 580 is continued so that it is constant at a temperature slightly lower than the temperature (36 ° C). In the following description, the surface temperature of the seating portion 510T that is maintained constant in the second maintenance period D8, that is, a temperature slightly lower than the toilet seat set temperature is referred to as a maintenance temperature.

[0363] Thus, in this example, after the user is seated on the toilet seat 13, the control device 700 gradually decreases the surface temperature of the seat portion 510T. This prevents the user from getting a low temperature burn. [0364] When the seating sensor 290 detects that the user has left the toilet seat 13 at time t8, the control device 700 stops driving the toilet seat heater 580 during the stop period D9. As a result, the surface temperature of the seating portion 510T decreases.

[0365] At time t9 when the surface temperature of the seating portion 510T reaches 18 ° C, the control device 700 starts low-power driving of the toilet seat heater 580 again, and the surface temperature of the seating portion 510T reaches 18 ° C. The low-power drive of the toilet seat heater 580 is maintained during the waiting period D10 so as to be constant.

[0366] In the second temperature rising period D4, the control device 700 is driving 600W of the toilet seat heater 580. The control device 700 gradually decreases the power for driving the toilet seat heater 580 to draw a parabola. Let's do it (see the thick line in the graph of the power supply rate, see the dotted line).

[0367] In this case, as indicated by the thick dotted line in the graph showing the surface temperature of the seating portion 510T, the temperature gradient gradually increases as the surface temperature of the seating portion 510T approaches a temperature slightly higher than the toilet seat set temperature. It becomes moderate.

[0368] When the temperature gradient gradually decreases as described above, the overshoot caused by the temperature change of the seating portion 510T can be sufficiently reduced.

In this example, after the user is seated on the toilet seat 13, the power used to drive the toilet seat heater 580 is adjusted to gradually reduce the surface temperature of the seat 510T.

The driving of 0 may be stopped when the user is seated on the toilet seat 13. Even in this case, it is possible to prevent the user from getting a low temperature burn.

[0370] Further, in this example, the surface temperature of the seating portion 510T is raised to a temperature slightly higher than the toilet seat set temperature, but the surface temperature of the seating portion 510T is increased to reach the toilet seat set temperature. May be.

[0371] (6-7) Effect of Toilet Seat Heater 580

 As described above, in the toilet seat device 100 according to the present embodiment, it is not always necessary to maintain the temperature of the toilet seat 13 at the toilet seat set temperature. Therefore, the current for driving the toilet seat heater 580 can be sufficiently reduced during the waiting periods Dl and D10 (FIG. 48) when the user does not enter the toilet room.

[0372] Thereby, even when the toilet seat heater 580 is turned on, the power consumption is sufficiently reduced.

. As a result, energy saving is realized. [0373] Further, the control device 700 of the toilet seat device 100 raises the surface temperature of the seating portion 510T to the limit temperature in a short time by driving the toilet seat heater 580 to 1200W. Thereafter, the control device 700 drives the toilet seat heater 580 to 600 W, and raises the surface temperature of the seating portion 510 T with a gentler temperature gradient than when 1200 W is driven.

 [0374] Thereby, the overshoot caused by the temperature change of the seating portion 510T is sufficiently reduced. As a result, the surface temperature of the seating portion 510T is accurately raised in a short time and stabilized at the toilet seat set temperature.

 [0375] (6-8) Other examples of toilet seat heater

 In this embodiment, in order to increase the surface temperature of the seating portion 510T, the surface temperature of the force seating portion 51OT using the toilet seat heater 580 including the rear lamp heater 581 and the front lamp heater 582 can be instantaneously increased. If possible, a heater provided with a heating wire may be used instead of the toilet seat heater 580, a heater provided with a strip-shaped resistor, or a planar heater may be used.

 [0376] FIG. 49 is a diagram illustrating an example of a heating unit of the seating portion 510T using a heating wire. Fig. 49 (a) shows a top view of the heating unit 680U, and Fig. 49 (b) shows a cross-sectional view taken along line Ql-Q 1 in Fig. 49 (a).

 [0377] As shown in Fig. 49 (a) and Fig. 49 (b), the heating unit 680U also has a linear heater 683 and two aluminum thin films 684a and 684b.

 [0378] Specifically, the linear heater 683 is arranged so as to meander across the entire lower surface of the upper toilet seat casing 410 at equal intervals, and the arranged linear heater 683 has substantially the same shape as the upper toilet seat casing 410. A heating unit 680U is manufactured by sandwiching two aluminum thin films 684a and 684b having the above and bonding them together with an adhesive having high heat resistance (high temperature adhesive).

 [0379] The linear heater 683 includes a core wire 683a, a heating wire 683b, and a covering tube 683c. In the linear heater 683, the heating wire 683b is wound around the core wire 683a. Further, the core wire 683a around which the heating wire 683b is wound is covered with a covering tube 683c.

[0380] Here, the coated tube 683c is formed of fluorine resin having high heat resistance. As a result, the electricity between the heating wire 683b and the core wire 683a and the anoleminium thin film 684a, 684b Insulation is ensured.

 [0381] The coated tube 683c may be formed of silicon rubber instead of fluorine resin.

 Even in this case, the insulation between the heating wire 683b and the core wire 683a and the aluminum thin films 684a and 684b is ensured by covering the heating wire 683b and the core wire 683a with silicon rubber having high heat resistance. .

 [0382] The coated tube 683c is made of fluorine resin and silicon as long as it can secure electrical insulation between the heating wire 683b and the core wire 683a and the anoremum thin film 684a and has high heat resistance. You may form with materials other than rubber | gum.

 [0383] However, the material constituting the coated tube 683c is, for example, a heat resistant material that can sufficiently withstand the impact of heat generated from the heating element 683b when the heating unit 680U is suddenly driven at 1000 W to 1200 W. Sex is required.
