Therefore, a small amount of washing water passes from the washing water inlet 143a to the inside of the inner cylinder 142 and flows out from the washing water outlets 143c and 143d as indicated by arrows W3 and W4.

Also, as shown in FIG. 14 (f), when the motor 141 rotates the inner cylinder 142 by 270 degrees, the chamfered portion around the hole 142 f of the inner cylinder 142 is the washing water outlet 143 d of the outer cylinder 143 To face. Therefore, the washing water passes from the washing water inlet 143a to the inside of the inner cylinder 142 and flows out from the washing water outlet 143d as indicated by the arrow W4.

As described above, when the motor 141 rotates based on the control signal from the control unit 4, any one of the holes 142e, 142f, and 142g of the inner cylinder 142 can be used as the flush water outlet 143b to the outer cylinder 143. Facing 143 e, the clean water flowing from the washing water inlet 143 a flows out from any of the washing water outlets 143 b to 143 e.

Figure 15 shows the flow rate of flush water flowing out to flush nozzle 1 from flush water outlet 143 c, 143 d of switching valve 14 a in Figure 13, and flush flow rate flush out to bidet nozzle 2 from flush water outlet 143 b FIG. 16 is a diagram showing the flow rate of wash water flowing out from the wash water outlet 143 e to the nozzle washing nozzle 3.

The horizontal axis of FIG. 15 shows the rotation angle of the motor 141, and the vertical axis shows the flow rate of wash water flowing out from the wash water outlets 143b to 143e. Also, the solid line Q1 shows the change in the flow rate of the washing water flowing out from the washing water outlet 143c to the posterior nozzle 1, and the alternate long and short dash line Q2 shows the flow rate of the washing water flowing out from the washing water outlet 1 43 d The dashed-dotted line Q3 shows the change in the flow rate of the wash water flowing out from the wash water outlet 143b to the bidet nozzle 2, and the broken line Q4 shows the change from the wash water outlet 143e through the instantaneous heating device 33. The change of the flow rate of the wash water which flows out to the nozzle 3 for a zulu washing is shown.

For example, as shown in Figure 15, if the motor 141 does not rotate (0 degrees), cleaning The flow rate Q3 of the washing water flowing out to the bidet nozzle 2 from the water outlet 134b shows the maximum value. Then, as the rotation angle of the motor 14 1 increases, the flow rate Q 3 of the washing water flowing out to the bidet nozzle 2 from the washing water outlet 1 4 3 decreases, and the nozzle for nozzle washing 3 from the washing water outlet 1 4 3 e The flow rate of flush water flowing out to the

Next, when the motor 141 rotates 90 degrees, the flow rate Q4 of the wash water flowing out from the wash water outlet 134e to the nozzle 3 for cleaning the nozzle indicates the maximum value. Then, the rotation angle of the motor 14 1 further increases, and the flow rate Q 4 of the washing water flowing out from the washing water outlet 1 43 e to the nozzle 3 for nozzle washing decreases, and the washing water outlet 1 4 3 c The flow rate Q1 of the flush water flowing out to the nozzle 1a increases.

Subsequently, when the motor 141 rotates 180 degrees, the flow rate Q1 of the flush water flowing out from the flush water outlet 14c to the nozzle 1a indicates the maximum value. Then, the rotation angle of the motor 14 1 further increases and the flow rate Q 1 of the washing water flowing out to the back nozzle 1 from the washing water outlet 1 4 3 c decreases, and the back nozzle 1 from the washing water outlet 1 4 3 d The flow rate Q2 of wash water flowing out to the

Subsequently, when the motor 141 rotates 270 degrees, the flow rate Q2 of the flush water flowing out from the flush water outlet 1 43 d to the nozzle 1a shows the maximum value. Then, as the rotation angle of the motor 14 1 further increases, the flow rate Q 2 of the wash water flowing out from the wash water outlet 1 4 3 d to the posterior nozzle 1 a decreases, and the bidet nozzle from the wash water outlet 1 4 3 b Flow rate Q3 of flush water flowing out to 2 increases.

As described above, the control unit 4 controls the flow rate of the wash water flowing out from the wash water outlet 1 4 3 b to 1 3 e by controlling the rotation angle of the switching valve 1 4 1 14 1 can do. Furthermore, in any case, the rotation angle of the switching valve 1 4 motor 1 4 1 is 1 24 2 e, 1 2 2 f, 1 2 4 g of the washing water outlet or the chamfered portion around them ( Since the recess) faces one of the washing water outlets 1 4 3 b 1 4 3 e, the flow path of the washing water is not blocked, and the washing water supplied from the washing water inlet 1 4 3 a is the washing water. Exit at any of the outlets 1 4 3 b 1 4 3 e.

FIG. 16 is a partially cutaway sectional view showing the structure of the instantaneous heating device 33. As shown in FIG. In Fig. 16, the instantaneous heating device 3 3 has a casing 5 0 4, a sheathed heater 5 0 5, a heat conductor 5 0 6, a piping 5 10 0, a temperature 3 3 a, a thermostat 3 3 b and a temperature Includes fuse 3 3 c.

The casing 504 has a substantially rectangular parallelepiped shape. In the casing 54, a piping 5 10 and a sheath heater 5 0 5 are provided side by side at a predetermined interval so as to extend in the longitudinal direction, and both ends of each casing are 5 5 It projects from the both end faces of 4 to the outside. In the casing 504, the piping 510 and the sheath heater 500 are covered with a heat conductor 5106. The sheathed heater 505 contains a heating wire and generates heat when power is supplied.

At the time of the above-described nozzle cleaning, the cleaning water supplied from the cleaning water outlet 1 43 e of the switching valve 14 a of FIG. 13 is introduced into the pipe 5 10 1 from the water supply port 5 11.

When power is supplied to the 5500 heat exchanger, the heat generated by the 5500 heat exchanger is transferred to the pipe 510 through the heat conductor 5106. As a result, the washing water introduced into the pipe 510 is heated, and the high temperature water for nozzle washing or the steam for nozzle washing is discharged from the discharge port 512.

Here, in FIG. 16, assuming that the water supply port 5 1 1 side of the piping 5 10 is the upstream side of the instantaneous heating device 3 3 and the exhaust port 5 1 2 side is the downstream side of the instantaneous heating device 3 3 3 3 a and Thermostat 3 3 b are provided on the downstream side of the instantaneous heating device 33. Also, the thermal fuse 33 c is provided on the side surface of the casing 504.

In the second embodiment, the reference temperature is different among the temperature sensor 33a, the thermostat 33b and the temperature fuse 33c. Thus, three stages of overheat prevention adjustment can be performed. Furthermore, even if one of the thermostat 33a, the thermostat 33b and the thermal fuse 33c fails, the remaining two prevent overheating.

The miss temperature 33 a is attached to the sheathed heater 5 0 5 and detects the temperature of the sheathed heater 5 0 5. The control unit 4 determines the temperature of the temperature 5 0 5 given from the temperature controller 3 3 a, and controls the temperature of the sheathed heater 5 5 to lower the temperature when it is overheated. Do.

The thermostat 3 3 b is attached so as to be able to detect the temperature of the washing water flowing in the piping 5 10. If the temperature of the washing water flowing in the piping 5 10 10 exceeds the operation reference temperature of the thermostat 3 3 b, the heat pump 3 3 b is a sheath heater 5 0 5 Operate to shut off the power supply of

Finally, the thermal fuse 33 c is closely fixed to the casing 504. If the temperature of the housing 54 4 exceeds the operation reference temperature of the thermal fuse 3 3 c, the power supply to the sheathed heater 5 0 5 is cut off by melting the thermal fuse 3 3 c.

The heat of the washing water by the sheath heater 505 and the sheath heat of the sheath itself are prevented by the function of the above thermistor 33a, the thermostat 33b and the temperature fuse 33c.

In the instant heating device 33 of the second embodiment, the sheath heater 505 is used as a heating device for washing water, but the present invention is not limited to this, and a heater, a ceramic heater, a print heater or the like may be used. May be

Furthermore, although each of the thermistors 33a, thermostat 33b and thermal fuse 33c prevents overheating of the instantaneous heating device 33, the controller of the thermostats 33a or thermostat 33b is controlled. By connecting with 4, the control unit 4 may perform feedback control or feed forward control of the temperature of the sheath 5 05 based on the temperature measurement value of the thermistor 3 a or the thermostat 33 b.

FIG. 17 is an external perspective view showing a part of the nozzle portion 30. FIG. In FIG. 17, a posterior nozzle 1a having a cylindrical shape and a bidet nozzle 2 are provided in parallel so as to be adjacent to each other, and a nozzle for cleaning the nozzle so as to cover the upper ends of the posterior nozzle 1a and the bidet nozzle 2. 3 is attached.

The tube 3 t is connected to the rear end of the nozzle cleaning nozzle 3, and the tube 3 t is connected to the outlet 5 1 2 of the instantaneous heating device 3 3. As a result, high-temperature water for nozzle cleaning or steam for nozzle cleaning is supplied from the instantaneous heating device 33 to the nozzle cleaning nozzle 3 through the tube 3 t.

Fig. 18 is a schematic cross-sectional view of the nozzle part when wash water is spouted from the posterior nozzle to the surface to be cleaned of the human body, and Fig. 19 is a high-temperature water or nozzle wash for nozzle wash from the nozzle wash nozzle. FIG. 6 is a schematic cross-sectional view of a nozzle when spray steam is ejected.

In FIGS. 18 and 19, the nozzle unit 30 is entirely or partially the main body unit. It is housed in a casing of 200 a.

Hereinafter, the washing of the local part of the human body by the posterior nozzle 1a is referred to as posterior washing.

The posterior nozzle la is comprised of a piston 20, a cylinder 21 and a spring 23. A wash water inlet 24a is provided on the rear end surface of the cylinder 21 and a wash water inlet 24b is provided on the side. First flow path 2 inside piston 20

A 0 a and a second flow passage 20 b are formed, and an ejection hole 25 is provided on the top surface of the tip of the piston 20.

Washing water is supplied from the washing water inlet 24 b of the cylinder 21 at the start of the buttock washing. As a result, as shown in FIG. 18, the piston 20 provided in the cylinder 21 projects out of the casing of the main body portion 200 a against the elastic force of the spring 23.

Thereafter, the washing water is supplied from the washing water inlets 24a and 24b of the cylinder 21. As a result, the wash water supplied from the wash water inlet 24 a is introduced into the first flow passage 20 a of the piston 20, and is jetted from the jet hole 25 while being given rotational force. Further, the washing water supplied from the washing water inlet 24 b is introduced into the second flow passage 20 b of the piston 20 and is jetted from the jet hole 25.

As described above, since a rotational force is given to the cleaning water sent from the first flow path 20 a to the ejection hole 25, the cleaning water ejected from the ejection hole 25 toward the surface to be cleaned of the human body is Have a wide angle. By adjusting the ratio between the flow rate of the washing water in the first flow passage 20 a and the flow rate of the washing water in the second flow passage 20 b using the switching valve 14 a described above, the ejection holes The spread angle of the washing water spouted from the 5 can be adjusted.

At the end of the hip washing, the supply of washing water to the washing water inlets 2 4 a and 2 4 of the cylinder 2 1 is stopped. Thereby, as shown in FIG. 19, the piston 20 is accommodated in the cylinder 21 by the elastic force of the spring 23. In this case, the piston 20 is held by the elastic force of the spring 23 while being housed in the cylinder 21 and therefore does not protrude from the main body portion 200 a.

The rear end face of the nozzle cleaning nozzle 3 is provided with a cleaning water inlet 24c, and the tip of the nozzle cleaning nozzle 3 is opposed to the ejection hole 25 of the rear nozzle 1a and the ejection hole of the bidet nozzle 2 described above. A nozzle cleaning hole 24 d is provided on the lower surface side. Nozzle washing Inside the cleaning nozzle 3, there is formed a flow passage 24e communicating the cleaning water inlet 24c with the nozzle cleaning hole 24d. As mentioned above, the washing water inlet 24c is connected to the outlet 512 of the instantaneous heating device 33 via the tube 3t (Fig. 17).

At the time of nozzle cleaning, high-temperature water for nozzle cleaning or steam for nozzle cleaning is supplied from the instantaneous heating device 33 to the cleaning water inlet 24 c of the nozzle 3 for nozzle cleaning. As a result, as shown in FIG. 19, high temperature water for nozzle cleaning or steam for nozzle cleaning is ejected from the nozzle cleaning holes 24 d through the flow path 24 e in the direction of the arrow J 1.

The high temperature water for nozzle cleaning or the vapor for nozzle cleaning ejected from the nozzle cleaning holes 24 d of the nozzle cleaning nozzle 3 is ejected around the ejection holes 25 of the posterior nozzle 1 a and the ejection holes of the bidet nozzle 2. As a result, the dirt adhering to the periphery of the ejection port 25 of the rear nozzle 1 a or the ejection port of the bidet nozzle 2 is exfoliated by the high-temperature water for nozzle cleaning or the vapor for nozzle cleaning, and is flowed into the toilet 600. . As a result, cleaning and sterilization are carried out around the jet holes 25 of the posterior nozzle 1 a and the jet holes of the bidet nozzle 2.

Figure 20 is a schematic cross-sectional view of the automatic closing toilet seat system provided on the main body part 200a of the sanitary washing device of Figure 10; Figure 21 is a schematic view of the automatic closing toilet seat system of Figure 20 1 is a cross-sectional view taken along the line F. FIG.

As shown in FIGS. 20 and 21, an inner case 45 is provided in the main unit 200a. In the inner case 450, there are provided an automatic toilet seat opening and closing device 460 and an automatic toilet lid opening and closing device 56. The automatic toilet seat opening and closing device 4 60 has a toilet seat opening and closing sensor 4 0 1, and the automatic toilet lid opening and closing device 5 6 0 has a toilet lid opening and closing sensor 5 0 1.

Automatic toilet lid opening and closing device 56 includes motor M 5 and gears 5 0 7 and 5 0 9. Motor M 5 rotation shaft 5 0 6 rotates in the direction of arrow R 5 0 0 and rotates gear 5 0 9 through gear 5 0 7. In addition, a toilet lid 500 is attached to the rotating shaft 5 0 8 of the gear 5 0 0 9 via a fixing portion 8 2 0 2 (see FIG. 2 1). As a result, the gear 5 0 9 rotates and the toilet lid 5 0 0 opens and closes.

Permanent magnets 5 1 1 a and 5 1 1 b are attached to gear 5 0 9 of automatic toilet lid opening / closing device 5 6 0 at an angle of approximately 90 degrees. Hall IC 5 1 3 a, 5 1 3 b is installed at the position facing the permanent magnet 5 1 1 a, 5 1 1 b with the toilet lid 5 00 closed. It is broken. Here, Hall IC 5 13 a and 5 1 3 b are magnetic sensors that use the Hall effect.

The automatic toilet seat opening and closing device 460 includes a motor M4 and gears 407 and 409. The rotating shaft 406 of the motor M 4 rotates in the direction of arrow R 400 and rotates the gear 40 9 through the gear 40 7. In addition, a toilet seat 400 is attached to the rotation shaft 408 of the gear 409. As a result, the gear 40 9 is rotated and the toilet seat 400 is opened and closed.

Permanent magnets 409 a and 40 9 b are attached to the gear 409 of the automatic toilet seat opening and closing device 460 at an angle of 90 degrees. Holes I C 420 a and 42 O b are provided at positions facing the permanent magnets 40 9 a and 409 b with the toilet seat 400 closed.

Next, FIG. 22 is a view for explaining the operation of the automatic closing / closing toilet lid device 560 of the toilet lid 500, and FIG. 23 shows the operation of the automatic opening / closing toilet lid device of FIG. FIG. 10 is a diagram showing signals transmitted from a, 5 13 b to the control unit 4;

Fig. 22 (a) shows the state where the toilet lid 500 is closed (the toilet lid rotation angle = 0 degree), and Fig. 22 (b) shows the condition where the toilet lid 500 is open (the toilet lid rotation angle = 90) Degree). As shown in FIG. 22, in the gear 509 of the automatic toilet lid opening / closing device 56, permanent magnets 51a and 51b are provided so as to form an angle of 90 degrees with each other.

The angle formed by the permanent magnets 5 1 1 a and 5 1 1 b is designed to be equal to the opening / closing angle of the toilet lid 500.

Therefore, as shown in FIG. 22 (a), when the toilet lid 500 is closed, that is, when the toilet lid rotation angle is 0 degrees, the permanent magnet 5 1 1 a is a Hall IC 5 1 3 a The permanent magnet 5 1 1 b faces the Hall IC 5 1 3 b.

As a result, as shown in FIG. 23, when the stool rotation angle is 0 degree, the Hall IC 5 13 a, 5 1 3 b is the magnetic generated by the permanent magnet 5 1 1 a, 5 1 1 b Detects a logic high (H) signal to the controller 4. As a result, the control unit 4 recognizes that the open / close state of the toilet lid is closed based on the signals from the holes I C 5 13 a and 5 13 b.

On the other hand, when the toilet lid 500 is opened by the automatic toilet lid opening / closing device 560, the automatic lid opening is performed. The gear 50 9 of the closing device 50 60 rotates in the direction of arrow X in FIG. As a result, the permanent magnets 5 1 1 a and 5 1 1 b attached to the gear 509 also rotate in the direction of the arrow X.

As shown in Fig. 22 (b), when the toilet lid 500 is open, that is, when the toilet lid rotation angle is 90 degrees, the permanent magnet 5 1 1 a faces the Hall IC 5 1 3 b. The permanent magnet 5 1 1 b does not face the Hall IC 5 13 a.

As a result, as shown in FIG. 23, when the toilet lid rotation angle is 90 degrees, the Hall IC 5 1 3 b detects the magnetism generated by the permanent magnet 5 1 1 a and outputs logic high (H The Hall IC 5 13 a can not detect the magnetism from the permanent magnets 5 1 1 a and 5 1 1 and transmits the signal of logic gate 1 (L) to the control portion 4. Send to Thereby, the control unit 4 recognizes that the open / close state of the toilet lid is open based on the signals from the holes I C 5 13 a and 5 13 b.

Next, the operation of the control unit 4 will be described. FIGS. 24 and 25 are flowcharts showing the operation of the control unit 4.

As shown in FIG. 24, first, the control unit 4 determines whether or not a nozzle cleaning operation signal has been received from the remote control device 300a (step S10). Here, the nozzle cleaning operation signal is a predetermined signal transmitted to the control unit 4 when the nozzle cleaning switch 309 is pressed.

When the controller 4 has not received the nozzle cleaning operation signal from the remote control device 300, it determines whether or not another signal has been received (step S1 1). When another signal is received, the control unit 4 performs a predetermined operation based on the other signal (step S12). For example, when the control unit 4 receives a signal from the remote control device 300 a that the back switch 3 0 3 is pressed, the control unit 4 controls so that the cleaning water is ejected from the back nozzle 1 a. On the other hand, if no other signal is received in step S11, the control unit 4 returns to step S10.

Next, when the nozzle cleaning operation signal is received from the remote control device 300a in step S10, the control unit 4 receives the output signals of the Hall ICs 513a and 513b (step S6). 13) .

Control unit 4 opens and closes the toilet lid based on the output signal of Hall IC 5 1 3 a, 5 1 3 b Determine (step SI 4). If it is determined that the toilet lid is closed, the control unit 4 returns to step S13.

In the second embodiment, the open / close of the toilet lid is determined based on the output signals of the Hall ICs 5 13 a and 5 13 b. However, the present invention is not limited to this. A seating sensor 51 for detecting the presence or absence of the user may be used on the unit 400. On the other hand, when it is determined that the toilet lid is open, the control unit 4 sends a heating instruction to the instantaneous heating device 33 (step S 15). As a result, the amount of heat generated from the series heater 5 05 increases.

Further, the control unit 4 instructs the rotation angle of the switching valve 14 a (step S 16). For example, the control unit 4 instructs the motor 14 1 to set the rotation angle of the switching valve 1 4 a shown in FIG. 15 to 90 degrees. As a result, the motor 14 1 is rotated, and flush water of flow Q 4 is supplied to the piping 5 10 of the instantaneous heating device 3 3. Then, high temperature water for nozzle cleaning heated by the action of the instantaneous heating device 33 is ejected from the nozzle cleaning nozzle 3 around the ejection holes 25 of the back nozzle 1 a or the ejection holes of the bidet nozzle 2.

As a result, the dirt adhering to the periphery of the ejection holes 25 of the posterior nozzle 1 a or the ejection holes of the bidet nozzle 2 is lifted and removed.

Thereafter, the control unit 4 determines whether or not a predetermined time has elapsed (step S17). The predetermined time in step S17 is a time required to spray the high-temperature water for nozzle cleaning around the jet holes 25 of the back nozzle 1a or the jet holes of the bidet nozzle 2 for cleaning. If the predetermined time has not elapsed, the control unit 4 returns to step S17, and stands by until the predetermined time elapses.

On the other hand, when the predetermined time has elapsed, the control unit 4 instructs the instantaneous heating device 33 to raise the heating temperature (step S 18). As a result, the amount of heat generated from the heater 505 increases.

Further, the control unit 4 instructs the rotation angle of the switching valve 1 4 a (step S 1 9). For example, the motor 14 1 is instructed to set the rotation angle of the switching valve 1 4 a of FIG. 15 to about 110 degrees. As a result, the motor 14 1 rotates and the washing water supplied to the pipe 5 10 of the instantaneous heating device 3 3 decreases. Therefore, high temperature water for nozzle cleaning is Transfer to the nozzle cleaning steam.

As a result, the high temperature nozzle cleaning vapor is ejected from the nozzle cleaning nozzle 3 around the ejection holes 25 of the posterior nozzle 1 a or the ejection holes of the bidet nozzle 2. Therefore, bacteria and stains fixed on the periphery of the jet holes 25 of the posterior nozzle 1 a or the jet holes of the bidet nozzle 2 are removed and disinfected. The nozzle portion 30 in the second embodiment is formed of a highly heat resistant resin which is not deformed even by the nozzle cleaning vapor or the nozzle cleaning high temperature water jet.

Thereafter, the control unit 4 determines whether or not a predetermined time has elapsed (step S 20). The predetermined time in step S20 is the time required to spray the nozzle cleaning vapor around the ejection holes 25 of the back nozzle 1a or around the ejection holes of the bidet nozzle 2 for cleaning and sterilization. . If the predetermined time has not elapsed, the control unit 4 returns to step S20 and waits until the predetermined time elapses.

On the other hand, when the predetermined time has elapsed, the control unit 4 transmits a heating stop instruction to the instantaneous heating device 33 (step S 21). As a result, the power supply to the series heater 500 of the instantaneous heating device 33 is stopped.

Subsequently, the control unit 4 determines whether or not a predetermined time has elapsed (step S 2 2). The predetermined time in step S22 is a time required for the temperature around the jet holes 25 of the posterior nozzle 1a or the jet holes of the bidet nozzle 2 to decrease. In addition, since this predetermined time depends on the outside air temperature, it may be set variably according to the season or the like. For example, it may be set to 4 to 6 seconds in summer and 1 to 3 seconds in winter.

If the predetermined time has not elapsed, the process waits until the predetermined time elapses. As a result, the temperature of the nozzle cleaning steam that has been heated by the instantaneous heating device 33 gradually decreases, and the nozzle cleaning steam is transferred to the nozzle cleaning high-temperature water, and the temperature further decreases. Cleaning water is spouted from the instantaneous heating device 33 through the nozzle cleaning nozzle 3 and spouted around the spout 25 of the posterior nozzle 1 a or the spout of the bidet nozzle 2. As a result, the spout of the posterior nozzle 1 a 25 The temperature around the area gradually decreases. As a result, the temperature of the nozzle unit 30 after sterilization can be lowered, so Reproduction can be suppressed.

On the other hand, when the predetermined time has elapsed, the rotation angle of the switching valve 14a is designated (step S23). For example, the motor 14 1 is instructed to set the rotation angle of the switching valve 1 4 a in FIG. 15 to about 135 degrees. As a result, the motor 14 1 rotates and the washing water supplied to the piping 5 10 of the instantaneous heating device 3 3 stops. As a result, the cleaning water ejected from the nozzle cleaning nozzle 3 is stopped.

Subsequently, the control unit 4 transmits a lamp lighting control signal for controlling lighting of the notification lamp 3 1 1 of the remote control device 3 0 0 a (step S 2 4). For example, a pulse lamp lighting control signal consisting of logic high (H) and logic low (L) is transmitted to the notification lamp 31 1. The notification lamp 3 1 1 lights up in the case of logic high based on the lamp lighting control signal, and goes out in the case of logic low. As a result, the notification lamp 3 1 1 blinks.

Further, the control unit 4 transmits a sound output control signal for controlling the output of sound from the speaker 310 to the speaker 320 of the remote control device 300a (step S 25). As a result, sound is output from the speaker 3 1 0 provided in the remote control device 3 0 0 a. For example, the control unit 4 repeatedly outputs the sound “The nozzle has been cleaned. Please use it with confidence.” From the speaker 310 or the sound is repeatedly output “Peep one”.

Subsequently, the control unit 4 determines whether or not a predetermined time has elapsed (step S 26). If the predetermined time has not elapsed, the control unit 4 returns to step S 24 and repeats the processes of step S 24 and step S 25. The predetermined time in step S 26 is a time for notifying the user that the nozzle cleaning has been completed.

On the other hand, when the predetermined time has elapsed, the control unit 4 transmits a lamp extinguishing control signal for controlling the extinguishment of the notification lamp 3 1 1 to the notification lamp 3 1 1 (step S 2 7). A sound stop control signal for controlling to stop the sound output is transmitted from the speaker 3 0 0 0 0 a (step S 2 8). As a result, the notification lamp 3 1 1 is turned off and the output of sound from the speaker 3 1 0 is stopped.

In the sanitary washing device 100a according to the present invention, the seating sensor 51, the hall IC 5 13a, 5 13b, and the toilet seat switch that the sanitary washing device 100 is not in use. Since cleaning of the posterior nozzle 1a and the bidet nozzle 2 by the nozzle cleaning nozzle 3 is permitted when detected by 5 5, the cleaning water from the nozzle cleaning nozzle 3 adheres to the human body when the sanitary cleaning device is used. Being prevented. As a result, it is possible to keep the posterior nozzle 1 a and the bidet nozzle 2 clean while giving the user a sufficient sense of security and ensuring the safety. Furthermore, exposure of the posterior nozzle 1a and the bidet nozzle 2 to high temperature steam facilitates the removal of the dirt adhering to the posterior nozzle 1a and the bidenozzle 2 and provides a sterilization effect. In addition, the diffusion range of steam expands the sterilization range at high temperature.

In addition, the posterior nozzle 1 a and the bidet nozzle 2 are flushed with steam or heated washing water, and then washed with non-heated cleansing water to be disinfected with the steam or heated washing water. Since the temperature of the nozzle a and the bidet nozzle 2 can be lowered, the user can be prevented from spouting the high-temperature washing water. In addition, it can also suppress the growth of bacteria.

Further, the washing water is instantaneously heated by the instantaneous heating device 33 to generate heated washing water or steam, and the water is jetted from the nozzle washing nozzle 3 to the posterior nozzle 1 a and the bidet nozzle 2. As a result, the posterior nozzle 1a and the bidet nozzle 2 are cleaned with the hot cleaning water or steam. Further, by adjusting the flow rate of the washing water supplied to the instantaneous heating device 33, the steam and the heated washing water are spouted from the nozzle washing nozzle 3. Therefore, it is possible to easily wash the posterior nozzle 1 a and the bidet nozzle 2 with steam or heated washing water by adjusting the flow rate of the washing water.

In the remote control device 300a according to the second embodiment, the nozzle 1a and the bidet nozzle 2 can be cleaned at any time by operating the nozzle cleaning switch 3 0 9 of the remote control device 300a. Operation is improved, and an instruction to start the cleaning operation of the nozzle cleaning nozzle 3 is invalidated by the operation of the cylinder lock switch 32 so that tampering and misoperation prevention by the child can be achieved. . Furthermore, since the end of the cleaning operation is notified after the cleaning operation by the nozzle cleaning nozzle 3 is completed, the user recognizes that the cleaning operation is continued until the end of the cleaning operation is notified. be able to. Thereby, the cleaning operation continues During this operation, the user is prevented from accidentally injecting the washing water from the nozzle 1 a and the bidet nozzle 2 and preventing the user from touching the washing water ejected from the nozzle 1 a and the bidet nozzle 2. Therefore, the posterior nozzle 1 a and the bidet nozzle 2 can be kept clean while securing safety.

Next, FIG. 26 is a schematic plan view showing another example of the remote control device of FIG. The remote control device 300a of FIG. 26 differs from the remote control device 300a of FIG. 11 in the following points. As shown in FIG. 26, the remote control device 3 00 b includes a liquid crystal display unit 3 1 3 instead of the speaker 3 1 0 of the remote control device 3 0 0 a and the notification lamp 3 1 1.

As a result, information can be displayed on the liquid crystal display unit 13 using characters, symbols, figures, and the like. For example, it is possible to display "nozzle sterilization complete" on the liquid crystal display unit 1313 using characters. As a result, the user can visually recognize that the nozzle cleaning has been completed and the sanitary cleaning device 100 can be used safely.

Next, FIG. 27 is a partially cutaway sectional view showing another example of the instantaneous heating device used for the sanitary washing device according to the present invention.

The instant heating device 3 3 a of FIG. 27 differs from the instant heating device 3 3 of FIG. 16 in the following points.

A sheathed heater 505 is provided in the casing 504a, and both ends of the sheathed heater 505 project outward from both end faces of the casing 505a. A cylindrical space 510 formed between the casing 5 0 4 a and the sheathed heater 5 0 5 plays a role of the pipe 5 1 0 in FIG.

At the time of the nozzle cleaning described above, the cleaning water supplied from the cleaning water outlet 1 43 e of the switching valve 14 in FIG. 13 is introduced into the cylindrical space 5 10 a from the water supply port 5 1 1 a When electric power is supplied to the sheathed heater 505, the heat generated by the sheathed heater 505 heats the cleaning water flowing through the cylindrical space 510a, and the high-temperature water or nozzle for cleaning the nozzle Cleaning vapor is discharged from the outlet 5 1 2 a.

In this case, in the instantaneous heating device 3 3 a, piping as in the instantaneous heating device 3 3 Since it is not necessary to form 10, cost can be reduced. In addition, since the sheathed heater 505 directly exchanges heat with the washing water, the heat exchange rate can be increased.

In the second embodiment, at the time of nozzle cleaning, high temperature water for nozzle cleaning, nozzle cleaning vapor and cleaning water are jetted from the nozzle 3 for nozzle cleaning to the posterior nozzle 1 a and the bidet nozzle 2 in this order. However, the present invention is not limited to this, and the nozzle cleaning steam, the nozzle cleaning high temperature water, and the cleaning water may be jetted to the posterior nozzle 1 a and the bidet nozzle 2 in any order. For example, the nozzle cleaning nozzle 3 may eject the high temperature water for nozzle cleaning, the nozzle cleaning vapor, the nozzle cleaning high temperature water, and the cleaning water in this order to the posterior nozzle 1 and the bidet nozzle 2.

Furthermore, in the present embodiment, the use condition of the sanitary washing device 100 is detected based on the opening and closing of the toilet lid 500 using the Hall IC 5 13 a and 5 13 b.

Hereinafter, the main body part 200a of the sanitary washing device 100a according to the third embodiment of the present invention will be described. The sanitary washing device 100 a according to the third embodiment is the same as the configuration of the sanitary washing device 100 a according to the second embodiment. In addition, the operation of the main body portion 200a of the sanitary washing device 100a according to the third embodiment is the same as the main body portion 200 of the sanitary washing device 100a according to the second embodiment. The difference from the operation of is as follows.

The operation of the control unit 4 of the main body unit 200 a of the sanitary washing device 100 a according to the third embodiment will be described. FIGS. 28 and 29 are flowcharts showing the operation of the control unit 4, and FIG. 30 is a diagram showing an example of control timing of the control unit 4.

The horizontal axis in Fig. 30 shows time, Fig. 30 (a) shows the timing of the heating device control signal HS, and Fig. 30 (b) shows the temperature change of the jet hole 25 of the posterior nozzle 1a. Fig. 3 0 (c) shows the lamp lighting control signal of the notification lamp 3 1 1 of the remote control device 3 0 0 a of Fig. 1 1.

As shown in FIG. 28, first, the control unit 4 determines whether a nozzle cleaning operation signal has been received from the remote control device 300 a (step S 30). Here, the nozzle cleaning operation signal is a predetermined signal transmitted to the control unit 4 when the nozzle cleaning switch 3 0 9 is pressed.

If the control unit 4 has not received the nozzle cleaning operation signal from the remote control device 300a, it determines whether any other signal has been received (step S31). If another signal is received, the control unit 4 performs a predetermined operation based on the other signal (step S 32). For example, the control unit 4 is a switch from the remote control device 3 0 0 a.

When 3 receives a pressed signal, control is performed so that rinse water is ejected from the posterior nozzle 1a. On the other hand, when no other signal is received in step S 31

, The controller 4 returns to step S30.

Next, when the nozzle cleaning operation signal is received from the remote control device 300a in step S30, the control unit 4 receives an output signal of the seating sensor 51 (step

S 3 3).

The control unit 4 determines the presence or absence of the human body on the toilet seat 400 based on the output signal of the seating sensor 51 (step S 34). If it is determined that a human body is present, the control unit 4 W

Return to step S33.

If it is determined that there is no human body, the control unit 4 sends a heating instruction to the instantaneous heating device 33 (step S35). As a result, the amount of heat generated from the sheathed heater 505 is increased. For example, as shown in FIG. 30 (a), the control unit 4 sends a pulse-like heating device control signal HS consisting of logic high (H) and logic low (L) to the instantaneous heating device 33. The instantaneous heating device 33 adjusts the on / off of the sheathed heater 505 based on the heating device control signal HS.

Further, the control unit 4 instructs the rotation angle of the switching valve 14a (step S36). For example, the control unit 4 instructs the motor 141 to set the rotation angle of the switching valve 14a shown in FIG. 15 to 90 degrees. As a result, the motor 141 is rotated, and flush water Q 4 is supplied to the piping 5 10 of the instantaneous heating device 33. Then, high-temperature water for nozzle cleaning heated by the action of the instantaneous heating device 33 is ejected from the nozzle cleaning nozzle 3 around the ejection holes 25 of the back nozzle 1 a or the ejection holes of the bidet nozzle 2. As shown in 3 0 (b), the temperature of the ejection holes 25 of the posterior nozzle 1 a rises. The dirt adhering to the periphery of the ejection holes 25 of the posterior nozzle 1 a or the ejection holes of the bidet nozzle 2 is lifted and removed.

Thereafter, the control unit 4 determines whether a predetermined time has elapsed (step S37). The predetermined time in step S37 is a time required to spray the high-temperature water for nozzle cleaning around the jet holes 25 of the back nozzle 1a or the jet holes of the bidet nozzle 2 for cleaning. If the predetermined time has not elapsed, the control unit 4 returns to step S37, and stands by until the predetermined time elapses.

On the other hand, when the predetermined time has elapsed, the control unit 4 instructs the instantaneous heating device 33 to raise the heating temperature (step S 38). As a result, the amount of heat generated from the sheathed heater 505 is increased.

Further, the control unit 4 instructs the rotation angle of the switching valve 14 a (step S 39). For example, the motor 141 is instructed to set the rotation angle of the switching valve 14 a in FIG. 15 to about 110 degrees. As a result, the motor 141 rotates and the washing water supplied to the pipe 510 of the instantaneous heating device 33 is reduced. Therefore, high temperature water for nozzle cleaning is Transfer to the nozzle cleaning steam.

Thereafter, the control unit 4 determines whether or not a predetermined time has elapsed (step S 4 0). The predetermined time in step S40 is the time required to spray the nozzle cleaning vapor around the ejection holes 25 of the back nozzle 1 a or the ejection holes of the bidet nozzle 2 for cleaning and sterilization. . If the predetermined time has not elapsed, the control unit 4 returns to step S40 and waits until the predetermined time elapses.

On the other hand, when the predetermined time has elapsed, the control unit 4 transmits a heating stop instruction to the instantaneous heating device 33 (step S 4 1). As a result, the power supply to the sheathed heater 505 of the instantaneous heating device 33 is stopped.

Subsequently, the control unit 4 determines whether or not a predetermined time has elapsed (step S 4 2). The predetermined time in step S 4 2 is the time required for the temperature around the ejection holes 25 of the back nozzle 1 a or the ejection holes of the bidet nozzle 2 to decrease, and corresponds to the time T 1 in FIG. Do. In addition, since this predetermined time depends on the outside air temperature, it may be set variably according to the season or the like. For example, it may be set to 4 to 6 seconds in summer and 1 to 3 seconds in winter.

In this case, as shown in FIG. 3 0 (b), the temperature of the jet holes 25 of the posterior nozzle 1 a gradually decreases.

If the predetermined time has not elapsed, the process waits until the predetermined time elapses. As a result, the temperature of the nozzle cleaning steam that has been heated by the instantaneous heating device 33 gradually decreases, and the nozzle cleaning steam is transferred to the nozzle cleaning high-temperature water, and the temperature further decreases. Cleaning water is spouted from the instantaneous heating device 33 through the nozzle cleaning nozzle 3 around the spout hole 25 of the back nozzle 1 a or the spout hole of the bidet nozzle 2 As a result, the temperature around the jet holes 25 of the posterior nozzle 1 a gradually decreases. As a result, since the temperature of the nozzle unit 30 after sterilization can be lowered, it is possible to suppress the growth of various bacteria.

On the other hand, when the predetermined time has elapsed, the rotation angle of the switching valve 14a is designated (step S43). For example, the motor 14 1 is instructed to set the rotation angle of the switching valve 1 4 a in FIG. 15 to about 135 degrees. As a result, the motor 1 4 1 rotates and the momentary heating device

3 3 piping 5 10 The flush water supplied to the water stops. As a result, the cleaning water ejected from the nozzle cleaning nozzle 3 is stopped.

Subsequently, the control unit 4 transmits a lamp lighting control signal for controlling lighting of the notification lamp 3 1 1 of the remote control device 3 0 0 a (step S 4 4). For example, as shown in FIG. 3 0 (c), a pulse-like lamp lighting control signal consisting of a logic high (H) and a logic gate (L) is transmitted to the notification lamp 3 1 1. The notification lamp 3 1 1 lights up in the case of logic high based on the lamp lighting control signal, and goes out in the case of logic low. As a result, the notification lamp 3 1 1 blinks.

Further, the control unit 4 transmits a sound output control signal for controlling the output of sound from the speaker 310 to the speed 310 of the remote control device 300a (step S 45). As a result, sound is output from the speaker 3 1 0 provided in the remote control device 3 0 0 a. For example, the control unit 4 repeatedly outputs "a nozzle has been cleaned. Please use it with confidence." And a sound is repeatedly output from a speaker 310.

Subsequently, the control unit 4 determines whether or not a predetermined time has elapsed (step S 4 6). If the control unit 4 has not passed the predetermined time, the process returns to step S44, and step S44 is performed.

Repeat step 4 and step S 4 5. The predetermined time in step S46 is a time for notifying the user that the nozzle cleaning has been completed, and corresponds to the time T2 in FIG.

On the other hand, when the predetermined time has elapsed, the control unit 4 transmits a lamp extinguishing control signal for controlling extinguishing of the notification lamp 3 1 1 to the notification lamp 3 1 1 (step S 4 7) and the remote control device 3. A sound stop control signal for controlling to stop the sound output is transmitted from the speaker 3 0 0 0 0 a (step S 4 8). Thus, the notification The lamp 3 1 1 is turned off and the sound output from the speaker 3 1 0 is stopped. In the sanitary washing device 100 a according to the present invention, the washing operation at high temperature by the nozzle washing nozzle 3 is finished, and the washing operation is finished after the temperature of the posterior nozzle 1 a is lowered. Since notification is given from the speaker 310, the user can recognize that the high temperature cleaning operation is continuing until the end of the cleaning operation is notified. As a result, the user may accidentally eject the washing water from the high temperature rear nozzle 1 a and the bidet nozzle 2 and may accidentally touch the high temperature rear nozzle 1 a and the bidet nozzle 2 while the cleaning operation at high temperature is continued. It is prevented. Therefore, it is possible to provide the user with a sufficient sense of security and to maintain the safety while keeping the nozzle 1a and the bidet nozzle 2 clean.

Furthermore, the notification lamp 31 1 and the spear force 3 10 10 stop notification of the end of the cleaning operation after a predetermined time has elapsed from the end of the cleaning operation by the nozzle cleaning nozzle 3, thereby preventing more than necessary notification. Wasteful power consumption is prevented. In addition, by using the speaker 310, even the elderly or the visually impaired user can aurally recognize that the washing operation at high temperature is finished. Therefore, the safety of various users is secured.

Also, by exposing the posterior nozzle 1a and the bidet nozzle 2 to high temperature steam, the dirt adhering to the posterior nozzle 1a and the bidet nozzle 2 floats up, the dirt is washed away with the high temperature washing water, and the germicidal effect is obtained Be In addition, the diffusion range of the steam expands the sterilization range at high temperatures.

In the sanitary washing apparatus according to the third embodiment, the end of the washing operation is notified after the washing operation of the rear nozzle 1a and the bidet nozzle 2 at high temperature by steam is finished, so that the washing operation at high temperature is continued The user is prevented from accidentally touching the high temperature steam, accidentally blowing the washing water from the high temperature rear nozzle 1 a and the bidet nozzle 2 and preventing the user from accidentally touching the high temperature rear nozzle 1 a and the bidet nozzle 2 It is done. Therefore, it is possible to keep the posterior nozzle 1a and the bidet nozzle 2 clean while securing safety.

Furthermore, by adjusting the flow rate of the washing water supplied to the instantaneous heating device 33, the washing water is ejected from the nozzle washing nozzle 3 with high temperature washing water or steam. did Therefore, the human body washing nozzle device can be easily washed with washing water having different physical properties by adjusting the flow rate of washing water.

In addition, the operation of the nozzle cleaning switch 3 0 9 provided in the remote control device 3 0 a can clean the back nozzle 1 a and the bidet nozzle 2 at any time, and the operability improves.

Fourth Embodiment

Hereinafter, the main body 200 b of the sanitary washing device 100 b according to the fourth embodiment of the present invention will be described.

FIG. 31 is a schematic view showing the configuration of a main body portion 200 b of a sanitary washing device 100 b according to a fourth embodiment of the present invention.

The main body part 200 b of FIG. 3 1 in the sanitary washing device 100 b is the anti-scaling substance supply device 34 in addition to the constitution of the main body part 200 a of the sanitary washing device 100 a in FIG. It is included. Details of the scale preventing substance supply device 34 will be described later.

FIG. 32 is a partially cutaway sectional view showing the structure of the instantaneous heating device 33. In Fig. 3 2, the instantaneous heating device 3 3 has a casing 5 0 4, a casing 5 5 0 5, a heat conductor 5 0 6, a piping 5 1 0, a thermistor 3 3 a, a thermostat 3 3 b and a temperature fuse 3 Including 3 c.

The casing 504 has a substantially rectangular parallelepiped shape. A pipe 510 and a sheath heater 5 0 5 are provided side by side in the casing 5 4 4 at predetermined intervals so as to extend in the longitudinal direction. It protrudes to the outside from both end faces. Here, one end side of the pipe 5 10 is made upstream of the instantaneous heating device 3 3, and the other end side of the pipe 5 1 10 is made downstream of the instantaneous heating device 3 3 One end of the pipe 501 is connected to a pipe 520 connected to the switching valve 14 in FIG.

A scale preventing substance supply device 34 is interposed in a pipe 520 on the upstream side of the instantaneous heating device 33. In the anti-scaling agent supply device 34, in the casing 54 that contains the anti-scaling agent, the piping 510 and the sheath heater 500 are covered with a heat conductor 5106. The series heater 505 contains a heating wire and generates heat when power is supplied. At the time of the above-mentioned nozzle cleaning, cleaning water is introduced into the pipe 5 10 from the water supply port 5 11 by the switching valve 14 a.

When electric power is supplied to the sheathed heater 505, the heat generated by the sheathed heater 505 is transferred to the pipe 510 through the heat conductor 506. As a result, the washing water introduced into the pipe 510 is heated, and the high temperature water for nozzle washing or the steam for nozzle washing is discharged from the discharge port 512.

The thermoset 33a and the thermostat 33b are provided downstream of the instantaneous heating device 33. In addition, the thermal fuse 33 c is provided on the side of the casing 504.

In the fourth embodiment, the operation reference temperature is different among the temperature sensor 33a, the thermostat 33b and the thermal fuse 33c. Thus, three stages of overheat prevention adjustment can be performed. Furthermore, even if one of the thermostat 33a, the thermostat 33b and the thermal fuse 33c fails, the remaining two prevent overheating.

The temperature sensor 3 a is attached to the sensor 1 05 5 and detects the temperature of the sheath heater 5 0 5. The control unit 4 determines the temperature of the sheath 5 500 given by the satellite 3 33 a, and performs control so as to lower the temperature of the sheath 5 5 when in the overheating state. .

The Thermostat 33 b is attached so as to be able to detect the temperature of the washing water flowing in the piping 510. If the temperature of the wash water flowing in the piping 5 10 exceeds the operation reference temperature of the thermostat 3 3 b, the thermostat 3 3 b operates to cut off the power supply of the sheath heater 5 0 5 .

Finally, the thermal fuse 33 c is closely fixed to the casing 50 4. If the temperature of the housing 54 4 exceeds the operation reference temperature of the thermal fuse 3 3 c, the power supply to the sheathed heater 5 0 5 is cut off by melting the thermal fuse 3 3 c.

The heat of the washing water by the heat of the heat treatment 5 0 5 and the heat of the heat of the heat 5 5 5 itself are prevented by the function of the heat treatment 3 a, the thermostat 3 3 b and the temperature fuse 3 3 c. Ru. In the instant heating device 33 according to the fourth embodiment, although the sheathed heater 505 is used as a heating device for the washing water, the present invention is not limited to this, and a self-powered heater, a ceramic heater, or a print heater Etc. may be used.

Furthermore, although each of the Thermos evening sun 33a, Thermostat 33b and thermal fuse 33c prevents overheating of the instantaneous heating device 33, the summer evening 33a or summer past 3 3b By connecting the control unit 4 to the control unit 4, the control unit 4 performs feedback control or feed-forward control of the temperature of the 5500 based on the temperature measurement value of the thermostat 33a or the thermostat 33b. You may

As the scale inhibitor, phosphoric acid compounds, acrylic acid or acrylic acid compounds can be used. Examples of phosphoric acid compounds include calcium phosphate, potassium phosphate, hexametaphosphate, monocalcium phosphate tripolyphosphate, magnesium aluminum tripolyphosphate, magnesium magnesium pyrophosphate, calcium metaphosphate, calcium sodium metaphosphate and the like. May be used, or a mixture of two or more may be used.

As the acrylic acid compound, acrylic acid / maleic acid copolymer compounds and the like can be used.

Thus, by supplying a phosphoric acid compound, acrylic acid or an acrylic compound to the washing water, the crystal form of the scale in the washing water is changed and the crystal growth is inhibited. Thereby, the deposition of the scale can be prevented, and the adhesion of the scale to the wall of the piping 5 10 of the instantaneous heating device 3 3 can be prevented.

In particular, it is preferable to use a mixture of calcium phosphate and potassium phosphate. In this case, the effect of scale adhesion prevention will last for a long time.

In addition, a chelating agent may be used as an anti-scaling agent. As chelating substances, ethylenediamine tetraacetic acid, hydroxyl ethylenediamine triacetic acid, dihydroxylethylenediamine diacetic acid, 1,3 propanediamine tetraacetic acid, triethylamine tetramine hexaacetic acid, ditrichloro triacetic acid, Alternatively, it is possible to use one or two or more kinds of dalconic acid and the like.

In this case, the scale is removed by the reaction of the chelating substance with metal ions in the scale. As a result, on the wall surface of piping 5 10 of instantaneous heating device 3 3 Scale adhesion is prevented.

In addition, a scale solubilizer may be used as a scale inhibitor. As the scale solubilizer, citric acid, hydrochloric acid, acetic acid, nitric acid or the like can be used.

In this case, the scale is dissolved and the scale is removed. Thereby, the adhesion of the scale on the wall surface of the piping 5 10 of the instantaneous heating device 3 3 is prevented. In addition, unnecessary components other than the scale component are also dissolved by the scale solubilizer. As a result, unnecessary components such as sodium ions and force lithium ions can be removed. A heater may be provided in the vicinity of the scale preventing substance supply device 34 for heating. As a result, the reaction between the scale solubilizer and the scale component is promoted, and the scale removal effect is enhanced.

As described above, the scale preventing agent is supplied to the washing water supplied to the instantaneous heating device 33 by the scale preventing material supply device 34. As a result, adhesion of scale on the wall of the piping 5 10 of the instantaneous heating device 3 3 is automatically prevented.

Furthermore, the cation exchange resin may be brought into contact with the washing water by providing the cation exchange resin in place of or in addition to the scale inhibitor in the scale inhibitor supply device 34. In this case, metal ions such as calcium and magnesium ions, which are the main components of the scale, are removed from the washing water, so high scale removal ability can be obtained. In addition, the coloring of washing water is prevented. As a cation exchange resin, for example, a strongly acidic cation exchange resin sodium type can be used.

Fifth Embodiment

FIG. 33 is a schematic perspective view of a portion of a sanitary washing device according to a fifth embodiment of the present invention.

As shown in FIG. 33, the sanitary washing apparatus according to the fifth embodiment of the present invention differs from the sanitary washing apparatus 100 b according to the fourth embodiment of the present invention in that Instead of or in addition to the scale preventing substance supply device 34, the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b are provided.

The vertical magnetic field generating magnet 5 1 4 a generates a vertical magnetic field, and the horizontal magnetic field generating magnet 5 1 4 b Generates a horizontal magnetic field. The vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b are composed of electromagnets and generate a magnetic field by energizing a coil (not shown).

As a result, magnetism can be applied to calcium ions, magnesium ions, and the like in the wash water flowing in the piping 510.

In addition, by using both the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b, it is possible to compensate for the respective non-acting areas of magnetism. Thereby, magnetism can be applied to the whole of the cleaning water flowing in the piping 5 10.

As described above, by causing magnetism to act on the cleaning water flowing in the pipe 510, ions of the same polarity gather and flow in the pipe 510. In this case, the ions are concentrated to accelerate the collision of the ions. Thereby, the aggregation and precipitation of ions are promoted. Therefore, aggregates of ions flow to the downstream side of the instantaneous heating device 33 without a scale being generated on the wall of the pipe 5 10. As a result, adhesion of scales on the wall surface of the piping 5 10 of the instantaneous heating device 3 3 is automatically prevented.

In addition, since the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 1 4 b operate semipermanently, no maintenance is required.

The vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b may be provided so as to be rotatable around the outer peripheral surface of the pipe 5 10 by means of an arrangement (not shown).

Also, the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b may be reciprocated in the axial direction of the pipe 5 10. Thereby, the ion shunt can be generated more effectively. This makes it possible to more effectively prevent the adhesion of the scale on the wall surface of the pipe 510.

Also, permanent magnets may be used as the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b. In this case, the supply of power can be eliminated.

Sixth Embodiment

FIG. 34 is a schematic view of part of a sanitary washing device according to a sixth embodiment of the present invention. As shown in FIG. 34, the sanitary washing device according to the sixth embodiment is the hygiene according to the fourth embodiment. The difference from the cleaning device 100 a is that an ultrasonic transducer S is provided in the piping 5 10 instead of or in addition to the anti-scaling material supply device 34. is there.

When an AC voltage having a resonance frequency is applied to the ultrasonic transducer S, a strong ultrasonic wave is generated by the resonance phenomenon. The ultrasonic waves generated by the ultrasonic transducer S propagate in the direction perpendicular to the vibration plane without being dispersed.

Therefore, the ultrasonic transducer S is provided at the refracting portion of the pipe 510 to propagate the ultrasonic wave in the flow direction of the washing water. As a result, fine bubbles (hereinafter referred to as cavitations) are generated in the washing water.

Cavitation generated in the wash water by ultrasonic waves evaporates carbonate ions in the wash water, which is the cause of the scale. As a result, the generation of scale can be prevented, and the adhesion of the scale on the wall of the piping 5 10 of the instantaneous heating device 3 3 can be automatically prevented. Also, since the ultrasonic transducer S operates semipermanently, no maintenance is required.

In the fourth, fifth and sixth embodiments described above, the posterior nozzle la and the bidet nozzle 2 correspond to the human body cleaning nozzle device, and the nozzle cleaning nozzle 3 corresponds to the nozzle cleaning device. 34 corresponds to the scale inhibitor supply device, the vertical magnetic field generating magnet 5 14 a and the horizontal magnetic field generating magnet 5 14 b correspond to the magnetism generating portion, and the ultrasonic transducer S corresponds to the ultrasonic wave generating portion .
