Next, the inner flow passage 143h is provided in the inner cylinder 142 so as to always communicate with the washing water inlet 143a when inserted into the outer cylinder 143. In addition, a hole (first valve body outlet) 142f and a hole (second valve body outlet) 142g are formed in this internal flow path 143h. The hole 142f is provided at a position corresponding to the washing water outlet 143b and the washing water outlet 143c of the outer cylinder 143, and the hole 142g is disposed at the washing water outlet 143d of the outer cylinder 143. It is installed in the corresponding position. By these configurations, the degree of communication between the washing water inlet 143a, the washing water outlet 143b, the washing water outlet 143c, and the washing water outlet 143d can be varied by the rotation angle of the inner cylinder 142. have.

In order to prevent internal leakage or to prevent external leakage, the O-ring 144 is provided as a sealing member for each flow path. However, the present invention is not limited thereto, and the load of the motor is used as a substitute for these O-rings. In order to alleviate, special O-rings, such as an X ring and V packing, may be used.

In the present embodiment, a stepping motor with a reduction gear built-in type which can be accurately positioned in the motor 141 is also mounted, and the output shaft is inserted into the inner cylinder 142. As described above, in the first embodiment, a stepping motor is employed as the motor 141. However, as long as the positioning accuracy can be ensured, a brush type general purpose DC motor can be used, and various actuators such as a rotary solenoid can be used. You may use it. In the first embodiment, although a rotary flow path switching valve is used, a flow path switching valve of a direct movement type, a flow path switching valve using a diaphragm, or a flow path switching valve for switching a plurality of flow paths into a disc type inner cylinder can also be used. .

In the above configuration, the anal nozzle 1 and the bidet nozzle 2 having the ejection holes 25 and 25e for discharging the washing water for cleaning the human body, and at least the anal nozzle 1 and the bidet nozzle 2 Nozzle cleaning including the instantaneous heating device 33 by the configuration of the sanitary washing device 100 having an instantaneous heating device (high temperature cleaning sterilizing device) 33 for high temperature cleaning and sterilizing the outer surfaces of the jet holes 25 and 25e. High temperature washing and sterilization of the outer surfaces of the ejection holes 25 and 25e of the anal nozzle 1 and the bidet nozzle 2 can be performed by the dragon nozzle 3. Therefore, when the sanitary washing apparatus 100 is used, the anal nozzle 1 and the bidet nozzle 2 can be kept clean by high temperature cleaning and sterilization, so that a person with chondropathy can use the sanitary washing apparatus 100 with confidence. have.

In addition, when hot water of high temperature is discharged from the nozzle cleaning nozzle 3 including the instantaneous heating device 33, sanitary washing is performed by a user pressurizing the nozzle cleaning switch 309 of the remote control device 300. The control unit (controller) 4 assembled in the apparatus 100 receives the high temperature cleaning sterilization mode signal and controls the operation of the high temperature cleaning sterilization.

That is, when the user pressurizes the nozzle cleaning switch 309, the control unit 4 drives the motor 141 of the selector valve 14 to communicate the washing water inlet 143a and the washing water outlet 143d. After the hot water from the heat exchanger 11 is supplied to the instantaneous heating device 33 to become hot water at a high temperature, the ejection holes 25 of the anal nozzle 1 and the bidet nozzle 2 from the nozzle cleaning nozzle 3 are formed. 25e) to control the high temperature cleaning sterilization.

Thus, since the sanitary washing apparatus 100 has the control part 4 and the instantaneous heating apparatus 33 which receive the high temperature washing sterilization mode signal, and control the operation | movement of high temperature washing sterilization, the sanitary washing apparatus 100 does not have to operate a human body without the hassle of operation. The anal nozzle 1 and the bidet nozzle 2 which have the jetting holes 25 and 25e which discharge the washing | cleaning water for this are at least the outer side of the jetting holes 25 and 25e of the anal nozzle 1 and the bidet nozzle 2, respectively. The surface is cleaned and sterilized at a high temperature, so that contamination by fungi and molds can be prevented, and hygiene can be maintained.

In addition, in the first embodiment, the nozzle cleaning switch 309 for transmitting the high temperature cleaning sterilization mode signal has been described with the configuration included in the remote operation device 300 of the sanitary washing apparatus 100. However, the sanitary washing apparatus 100 The structure provided in the main-body part 200 of () may be sufficient.

Thus, the nozzle cleaning switch 309 is provided with the nozzle cleaning switch 309 for transmitting the high temperature cleaning sterilization mode signal to the main body 200 or the remote control device 300 of the sanitary washing apparatus 100. The high temperature cleaning sterilization can be easily performed simply by pressing).

In addition, by sterilizing the anal nozzle 1 and the bidet nozzle 2 using high temperature hot water by the instantaneous heating device 33, contamination by fungus or mold by sterilizing action by high temperature hot water. This does not occur, and the anal nozzle 1 and the bidet nozzle 2 can be maintained hygienically.

Moreover, 55 degreeC-100 degreeC is preferable, as for the temperature of the high temperature water sterilizing this high temperature washing | cleaning, 55 degreeC-70 degreeC is more preferable, and 60 degreeC-70 degreeC is the most preferable. Because the results of the investigation, there are examples of sterilization of beer in the food field 55-60 ℃, sterilization degree of Cheongju 55-60 ℃, doenjang sterilization around 60 ℃, etc. In addition, the killing temperature of pathogenic bacteria is erythritis, typhoid bacteria , Paratyphoid bacteria, Escherichia coli, enteritis vibrio, burcellella, streptococci, staphylococci and the like are all known to be 60 ° C. The investigation result of the bactericidal effect of these bacteria is mentioned later.

Also in the result of experiment with E. coli, bactericidal effect was confirmed at 55 ° C. The higher the temperature, the greater the high temperature sterilization action, but the upper limit temperature is preferably 70 ° C. Thus, since the temperature of hot water is set to 55 degreeC-70 degreeC, even if a human body contacts high temperature water, there is no worry about a big thing, and contamination by fungus and mold can be prevented effectively.

The nozzle cleaning nozzle 3 is provided in a branch path different from the path for supplying the washing water to the anal nozzle 1 and the bidet nozzle 2. By this structure, since the instantaneous heating apparatus 33 is provided in the other branch path | route which does not communicate with the anal nozzle 1 and the bidet nozzle 2, high temperature water from the anal nozzle 1 and the bidet nozzle 2 It does not discharge and contacts a human body, and high temperature washing sterilization of the anal nozzle 1 and the bidet nozzle 2 can be performed safely. Moreover, since hot washing water is not supplied to the path | route supplied to the anal nozzle 1 and the bidet nozzle 2, the material which comprises a path | route, the material of the middle heat exchanger 11, and the switching valve 14 is There is no need for special heat-resistant materials.

In addition, at the time of high temperature cleaning sterilization, the control part 4 controls the flow rate of the hot water passing through the instantaneous heating device 33 to a predetermined flow rate. That is, the flow volume which flows through the instantaneous heating apparatus 33 is controlled by the control part 4 by setting the communication opening degree of the washing | cleaning water inlet 143a and the washing | cleaning water outlet 143d of the switching valve 14 to predetermined amount. The control unit 4 can obtain a flow rate signal from the flow rate sensor 10. By controlling the flow rate of the hot water at a predetermined flow rate, it is possible to prevent the hot water from being scattered by the human body, which is safe. In addition, the heat input required in order to make hot water controlled at a constant temperature of 40 ° C. in the heat exchanger 11 to high temperature water at a constant temperature of 60 ° C. in the instantaneous heating device 33 is a flow rate of the hot water. Theoretically determined by As a result, by controlling the high temperature water flow rate passing through the instantaneous heating device 33 to a predetermined flow rate, there is no need to provide a temperature sensor of the instantaneous heating device 33. Furthermore, by controlling at a small predetermined flow rate, the amount of heat required for heating with the sheath heater 505 can be reduced, and the above-mentioned safety and energy saving effect can be obtained.

In addition, the sheath heater 505 of the instantaneous heating apparatus 33 is a magnetic temperature control heater. As a result, the electric input is automatically controlled by the magnetic temperature control sheath heater 505 itself so as to be a constant high temperature water temperature of 60 ° C., for example, without attaching a temperature sensor or the like to the instantaneous heating device 33. For this reason, the instantaneous heating apparatus 33 can be made compact, the temperature of the hot water is almost constant, and the sterilization effect can be stabilized, and the user can use it with confidence. However, the sheath heater 505 of the instantaneous heating device 33 does not necessarily need to be a magnetic temperature control heater, and may be a general ceramic heater as long as only the temperature control can be safely performed.

In addition, the anal nozzle 1 and the bidet nozzle 2 are normally accommodated in the main body 200 of the sanitary washing apparatus 100 and protrude from the main body 200 of the sanitary washing apparatus 100 at the time of washing the human body. The anal nozzle 1 and the bidet nozzle 2 are stored in the main body 200 of the sanitary washing apparatus 100 so that the hot water from the nozzle cleaning nozzle 3 does not touch the human body during the high temperature cleaning sterilization. It is the structure which prohibits the operation operation | movement of high temperature washing sterilization except in a state. That is, when the user cleans the human body with the anal nozzle 1 and the bidet nozzle 2, even if the operation button (nozzle cleaning switch 309) instructing the high temperature cleaning sterilization of the remote control device 300 is wrongly pressed, The control part 4 controls so that operation operation of high temperature cleaning sterilization may not be performed. That is, the signal of the nozzle cleaning switch 309 is influenced by the controller 4 only when the anal nozzle 1 and the bidet nozzle 2 are housed in the main body 200 of the sanitary washing apparatus 100. This configuration is not received. As a result, the user can use the product without worrying about an image or the like.

Moreover, at the time of high temperature washing sterilization, it is the structure which simultaneously washes and sterilizes the some nozzle of the anal nozzle 1 and the bidet nozzle 2 with the high temperature water at the nozzle cleaning hole (hot water discharge port) 24d, Also in the case of using the anal nozzle 1 and the bidet nozzle 2 later, the anal nozzle 1 and the bidet nozzle 2 sterilized at high temperature can be used. Thereby, the user can wash the local parts with confidence in a sterilized and clean state.

In addition, by forming the part in which the temperature of the hot water of 55 degreeC-70 degreeC high temperature in the anal nozzle 1 and the bidet nozzle 2 acts by the heat-resistant material which fully endures the high temperature, There is no worry of deformation | transformation, damage, etc. of the anal nozzle 1 and the bidet nozzle 2 by this, and can use it in peace for a long term.

Furthermore, by forming the part which the temperature of the hot water of 55 degreeC-70 degreeC high temperature in the anal nozzle 1 and the bidet nozzle 2 acts by stainless steel, it is enough to withstand the high temperature, and is clean It is also high, and the effect of high temperature washing sterilization can be heightened more.

In addition, by making the anal nozzle 1 and the bidet nozzle 2 coat | cover the metal on the surface of resin, even if the flow path or external shape of the anal nozzle 1 and the bidet nozzle 2 is three-dimensional curved shape, By forming a metal film on at least a portion of the surface of the resin by, for example, plating a metal on the resin surface, the effect of high temperature cleaning sterilization on the surfaces of the anal nozzle 1 and the bidet nozzle 2 can be achieved. It can be higher.

In addition, by performing water repellent treatment on the surfaces of the anal nozzle 1 and the bidet nozzle 2, it is possible to prevent the scale from adhering to the anal nozzle 1 and the bidet nozzle 2, so that high temperature cleaning sterilization is possible. Can increase the effect.

In addition, the instantaneous heating device 33 is configured not only when the nozzle cleaning switch 309 of the remote control device 300 is pressed but also automatically high temperature cleaning sterilization at predetermined time intervals. Even when the sanitary washing apparatus 100 is not used, the anal nozzle 1 and the bidet nozzle 2 are automatically hot-sterilized and sterilized at predetermined time intervals, so that contamination by fungus and mold does not occur and is always performed. It is possible to provide a sanitary washing apparatus 100 that can be kept sanitary and clean.

As described above, any one of the holes 142e, 142f, and 142g of the inner cylinder 142 is rotated based on the control signal from the control unit 4 so that the washing water outlet of the outer cylinder 143 The washing water flowing in from the washing water inlet 143a flows out from any one of the washing water outlets 143b to 143e opposite to 143b to 143e.

FIG. 15 shows the flow rate of the washing water flowing out from the washing water outlets 143c and 143d of the switching valve 14a of FIG. 13 to the anal nozzle 1, and the washing flowing out from the washing water outlet 143b to the bidet nozzle 2. It is a figure which shows the flow volume of water and the flow volume of the washing water which flows out into the nozzle washing nozzle 3 from the washing | cleaning water outlet 143e.

15 represents the rotation angle of the motor 141, and the vertical axis represents the flow rate of the washing water flowing out of the washing water outlets 143b to 143e. Moreover, the solid line Q1 represents the change of the flow volume of the washing water which flows out from the washing water outlet 143c to the anal nozzle 1, and the dashed-dotted line Q2 moves from the washing water outlet 143d to the anal nozzle 1a. The change in the flow rate of the washing water flowing out is shown, the dashed-dotted line Q3 represents the change in the flow rate of the washing water flowing out from the washing water outlet 143b to the bidet nozzle 2, and the broken line Q4 is the washing water outlet ( The change of the flow volume of the washing | cleaning water which flows out from the 143e through the instantaneous heating apparatus 33 to the nozzle washing nozzle 3 is shown.

For example, as shown in FIG. 15, when the motor 141 does not rotate (0 degrees), the flow rate Q3 of the washing water flowing out from the washing water outlet 143b to the bidet nozzle 2 is at maximum. Indicates a value. Then, as the rotation angle of the motor 141 increases, the flow rate Q3 of the washing water flowing out from the washing water outlet 143b to the bidet nozzle 2 decreases, and the nozzle for washing the nozzle from the washing water outlet 143e. The flow rate Q4 of the washing water flowing out to (3) increases.

Next, when the motor 141 is rotated 90 degrees, the flow rate Q4 of the washing water flowing out from the washing water outlet 143e to the nozzle washing nozzle 3 shows the maximum value. Then, as the rotation angle of the motor 141 becomes larger, the flow rate Q4 of the washing water flowing out from the washing water outlet 143e to the nozzle washing nozzle 3 decreases, and the anal fluid from the washing water outlet 143c is reduced. The flow rate Q1 of the washing water flowing out to the nozzle 1a is increased.

Subsequently, when the motor 141 rotates 180 degrees, the flow rate Q1 of the washing water flowing out from the washing water outlet 143c to the anal nozzle 1a represents the maximum value. As the rotation angle of the motor 141 becomes larger, the flow rate Q1 of the washing water flowing out from the washing water outlet 143c to the anal nozzle 1 decreases, and the anal nozzle (from the washing water outlet 143d) decreases. The flow rate Q2 of the washing water flowing out to 1) increases.

Subsequently, when the motor 141 rotates 270 degrees, the flow rate Q2 of the washing water flowing out from the washing water outlet 143d to the anal nozzle 1a represents the maximum value. Then, while the rotation angle of the motor 141 becomes larger, the flow rate Q2 of the washing water flowing out from the washing water outlet 143d to the anal nozzle 1a decreases, and the bidet nozzle (from the washing water outlet 143b) decreases. The flow rate Q3 of the washing water flowing out to 2) increases.

As described above, the control unit 4 can control the flow angle of the washing water flowing out of the washing water outlets 143b to 143e by controlling the rotation angle of the motor 141 of the switching valve 14. In addition, even when the rotation angle of the motor 141 of the selector valve 14 is any, any one of the washing water outlets 142e, 142f, and 142g or the chamfer (a recessed part) around them is used as the washing water outlet 143b. Since the flow path of the washing water is not blocked, the washing water supplied from the washing water inlet 143a flows out from any one of the washing water outlets 143b to 143e.

16 is a partially cutaway sectional view showing the structure of the instantaneous heating device 33. In FIG. 16, the instantaneous heating device 33 includes a casing 504, a sheath heater 505, a heat conductor 506, a pipe 510, a thermistor 33a, a thermostat 33b, and a thermal fuse 33c. It includes.

The casing 504 has a substantially rectangular parallelepiped shape. In the casing 504, the pipe 510 and the sheath heater 505 are provided at predetermined intervals so as to extend in the longitudinal direction, and both ends protrude outward from both end surfaces of the casing 504.

In the casing 504, the pipe 510 and the sheath heater 505 are covered with a heat conductor 506. The sheath heater 505 incorporates a heating wire and generates heat by supplying electric power.

In the nozzle cleaning described above, the washing water supplied from the washing water outlet 143e of the switching valve 14a of FIG. 13 is introduced into the pipe 510 from the water supply port 511.

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

Here, in FIG. 16, when the water supply port 511 side of the piping 510 is an upstream side of the instantaneous heating apparatus 33, and the discharge port 512 side is a downstream side of the instantaneous heating apparatus 33, the thermistor 33a ) And the thermostat 33b are provided downstream of the instantaneous heating device 33. The thermal fuse 33c is provided on the side of the casing 504.

In the second embodiment, the thermistor 33a, the thermostat 33b, and the temperature fuse 33c are different from each other in operation reference temperature. Thereby, three steps of overheat prevention can be adjusted. In addition, even if any one of the thermistor 33a, the thermostat 33b, and the thermal fuse 33c fails, overheating is prevented by the remaining two.

The thermistor 33a is attached to the sheath heater 505 and detects the temperature of the sheath heater 505. The control unit 4 determines the temperature of the sheath heater 505 supplied from the thermistor 33a, and controls the temperature of the sheath heater 505 to be lowered when it is in an overheated state.

The thermostat 33b is attached so that the temperature of the washing water which flows in the piping 510 can be detected. When the temperature of the washing water flowing in the pipe 510 exceeds the operation reference temperature of the thermostat 33b, the thermostat 33b operates to cut off the power supply of the sheath heater 505.

Finally, the thermal fuse 33c is tightly fixed to the casing 504. When the temperature of the casing 504 exceeds the operating reference temperature of the thermal fuse 33c, the supply of power to the sheath heater 505 is cut off by melting the thermal fuse 33c.

By the operation of the thermistor 33a, the thermostat 33b, and the temperature fuse 33c, the overheating of the washing water by the sheath heater 505 and the overheating of the sheath heater 505 itself are prevented.

In the instantaneous heating device 33 of the second embodiment, the sheath heater 505 is used as the heating device for the washing water, but the present invention is not limited thereto. A mica heater, a ceramic heater or a print heater may be used. .

In addition, although the thermistor 33a, the thermostat 33b, and the thermal fuse 33c prevent the overheating of the instantaneous heating apparatus 33, respectively, the thermistor 33a or the thermostat 33b is connected with the control part 4; By doing so, the control unit 4 may perform feedback control or feedforward control of the temperature of the sheath heater 505 based on the temperature measurement of the thermistor 33a or the thermostat 33b.

17 is an external perspective view showing a part of the nozzle unit 30. In Fig. 17, the anal nozzle 1a having a cylindrical shape and the bidet nozzle 2 are provided in parallel so as to be adjacent to each other, and the nozzle cleaning nozzles are formed so as to cover the upper end portions of the anal nozzle 1a and the bidet nozzle 2. 3) is equipped.

A tube 3t is connected to the rear end of the nozzle cleaning nozzle 3, and the tube 3t is connected to the outlet 512 of the instantaneous heating device 33. Thereby, the hot water for nozzle cleaning or the steam for nozzle cleaning is supplied from the instantaneous heating apparatus 33 to the nozzle cleaning nozzle 3 via the tube 3t.

Fig. 18 is a schematic cross-sectional view of the nozzle portion in the case where the washing water is jetted from the anal nozzle toward the to-be-cleaned surface of the human body, and Fig. 19 is the nozzle portion in the case where the nozzle cleaning hot water or the nozzle cleaning steam is ejected from the nozzle cleaning nozzle. It is typical sectional drawing.

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

Hereinafter, washing of the local part of the human body by the anal nozzle 1a is called anal washing (usually called washing).

The anal nozzle 1a is composed of a piston 20, a cylinder 21, and a spring 23. The washing water inlet 24a is provided in the rear end surface of the cylinder 21, and the washing water inlet 24b is provided in the side part. The 1st flow path 20a and the 2nd flow path 20b are formed in the piston 20, and the blowing hole 25 is provided in the upper surface of the front-end | tip part of the piston 20. As shown in FIG.

At the start of anal cleansing, the washing water is supplied from the washing water inlet 24b of the cylinder 21. Thereby, as shown in FIG. 18, the piston 20 provided in the cylinder 21 protrudes out of the casing of the main-body part 200a against the elastic force of the spring 23. As shown in FIG.

Thereafter, the washing water is supplied from the washing water inlets 24a and 24b of the cylinder 21. As a result, the washing water supplied from the washing water inlet 24a is introduced into the first flow path 20a of the piston 20, and is ejected by the spray hole 25 while the rotational force is supplied. In addition, the washing water supplied from the washing water inlet 24b is introduced into the second flow path 20b of the piston 20, and is ejected by the spray hole 25.

Thus, since the rotational force is supplied to the washing | cleaning water sent from the 1st flow path 20a to the spray hole 25, the washing water sprayed from the spray hole 25 toward the to-be-cleaned surface of a human body has an enlarged angle. Has The washing blown out from the jet hole 25 by adjusting the ratio of the flow rate of the washing water in the 1st flow path 20a and the flow rate of the washing water in the 2nd flow path 20b using the above-mentioned switching valve 14a. You can adjust the zoom angle of the number.

At the end of anal cleansing, the supply of the washing water to the washing water inlets 24a and 24b of the cylinder 21 is stopped. As a result, 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 does not protrude from the main body 200a because the piston 20 is held in the state accommodated in the cylinder 21 by the elastic force of the spring 23.

The rear face of the nozzle cleaning nozzle 3 is provided with a washing water inlet 24c, and the nozzle for cleaning nozzles so as to face the jet hole 25 of the anal nozzle 1a and the jet hole of the bidet nozzle 2 described above. The nozzle cleaning hole 24d is provided in the front end lower surface side of (3). Inside the nozzle cleaning nozzle 3, a flow passage 24e communicating with the washing water inlet 24c and the nozzle cleaning hole 24d is formed. As described 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, hot water for nozzle cleaning or steam for nozzle cleaning is supplied from the instantaneous heating device 33 to the washing water inlet 24c of the nozzle cleaning nozzle 3. As a result, as shown in FIG. 19, the hot water for nozzle cleaning or the steam for nozzle cleaning is ejected from the nozzle cleaning hole 24d in the direction of the arrow J1 through the flow passage 24e.

The high temperature water for nozzle cleaning or the steam for nozzle cleaning ejected from the nozzle cleaning hole 24d of the nozzle cleaning nozzle 3 is formed around the ejection hole 25 of the anal nozzle 1a and the ejection hole of the bidet nozzle 2. Is blown out. As a result, dirt adhering around the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2 is separated by hot water for nozzle cleaning or steam for nozzle cleaning, and into the toilet 600. Flow. As a result, the cleaning and sterilization of the periphery of the blowing hole 25 of the anal nozzle 1a and the blowing hole of the bidet nozzle 2 are performed.

FIG. 20 is a schematic cross-sectional view of the automatic open / close toilet seat system installed in the main body 200a of the sanitary washing apparatus of FIG. 10, and FIG. 21 is a cross-sectional view taken along line F-F of the automatic open / close toilet seat system of FIG. 20.

As shown in FIG. 20 and FIG. 21, the inner case 450 is provided in the main-body part 200a. In the inner case 450, an automatic toilet seat opening and closing device 460 and an automatic toilet cover opening and closing device 560 are provided. The automatic toilet seat opening and closing device 460 has a toilet seat opening and closing sensor 401, and the automatic toilet seat opening and closing device 560 has a toilet seat opening and closing sensor 501.

The automatic toilet lid opening and closing device 560 includes a motor M5 and gears 507 and 509. The rotating shaft 506 of the motor M5 rotates in the direction of the arrow R500, and rotates the gear 509 via the gear 507. In addition, the toilet lid 500 is attached to the rotation shaft 508 of the gear 509 via a fixing part 820 (see FIG. 21). As a result, the gear 509 rotates and the opening and closing operation of the toilet lid 500 is performed.

Permanent magnets 511a and 511b are attached to the gear 509 of the automatic toilet lid opening and closing device 560 so as to form an angle of almost 90 degrees. Hall ICs 513a and 513b are provided at positions facing the permanent magnets 511a and 511b in a state in which the toilet lid 500 is closed. Here, the hall ICs 513a and 513b are magnetic sensors using 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 M4 rotates in the direction of the arrow R400, and rotates the gear 409 via the gear 407. The toilet seat 400 is attached to the rotation shaft 408 of the gear 409. As a result, the gear 409 rotates and the opening and closing operation of the toilet seat 400 is performed.

Permanent magnets 409a and 409b are attached to the gear 409 of the automatic toilet seat opening and closing device 460 to form an angle of 90 degrees. Hall ICs 420a and 420b are provided at positions facing the permanent magnets 409a and 409b in a state in which the toilet seat 400 is closed.

Next, FIG. 22 is a figure explaining operation | movement of the automatic switching toilet cover apparatus 560 of the toilet lid 500, and FIG. 23 is a hole IC 513a by operation | movement of the automatic switching toilet lid apparatus 560 of FIG. 513b shows a signal transmitted to the control unit 4.

FIG. 22A illustrates a state in which the toilet cover 500 is closed (toilet cover rotational movement angle = 0 degrees), and FIG. 22B illustrates a state in which the toilet cover 500 is open (toilet cover rotational movement angle = 90 degrees). Illustrated.

As shown in FIG. 22, in the gear 509 of the automatic toilet cover opening and closing apparatus 560, permanent magnets 511a and 511b are provided so as to form an angle of 90 degrees to each other.

In addition, the angle formed by the permanent magnets 511a and 511b is designed to be the same as the opening / closing angle of the toilet lid 500.

Therefore, as shown in FIG. 22A, when the toilet lid 500 is closed, that is, when the toilet lid rotation movement angle is 0 degrees, the permanent magnet 511a faces the hall IC 513a and the permanent magnet 511b. ) Opposes the hall IC 513b.

As a result, as shown in Fig. 23, when the toilet lid rotational movement angle is 0 degrees, the hall ICs 513a and 513b detect the magnetism generated by the permanent magnets 511a and 511b to determine the logic high H. The signal is transmitted to the control unit 4. Thereby, the control part 4 recognizes that the opening / closing state of the toilet lid is closed based on the signal from the hall ICs 513a and 513b.

On the other hand, when the toilet lid 500 is opened by the automatic toilet lid opening and closing device 560, the gear 509 of the automatic toilet lid opening and closing device 560 rotates in the direction of the arrow X in FIG. 22. As a result, the permanent magnets 511a and 511b attached to the gear 509 also rotate in the direction of the arrow X. FIG.

As shown in Fig. 22B, when the toilet lid 500 is open, that is, when the toilet lid rotational movement angle is 90 degrees, the permanent magnet 511a faces the hole IC 513b, but the permanent magnet 511b. Does not face the hall IC 513a.

As a result, as shown in FIG. 23, when the toilet lid rotational movement angle is 90 degrees, the hall IC 513b detects the magnet generated by the permanent magnet 511a and controls the signal of the logic high H to be controlled by the control unit 4. ), The hall IC 513a cannot detect the magnetism in the permanent magnets 511a and 511b, and transmits a signal of the logic low L to the controller 4. Thereby, the control part 4 recognizes that the opening / closing state of the toilet lid is closed based on the signal from the hall ICs 513a and 513b.

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

As shown in FIG. 24, first, the control part 4 determines whether the nozzle cleaning operation signal was received by the remote control apparatus 300a (step S10). Here, the nozzle cleaning operation signal is a predetermined signal transmitted to the control unit 4 by the nozzle cleaning switch 309 being pressed.

When the control unit 4 does not receive the nozzle cleaning operation signal by the remote control device 300a, it determines whether or not another signal is received (step S11). When receiving another signal, the control unit 4 performs a predetermined operation based on the other signals (step S12). For example, when the control unit 4 receives a signal in which the anal switch 303 is pressed by the remote control device 300a, the controller 4 controls the anal nozzle 1a to eject the washing water. On the other hand, when 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 by the remote control device 300a in step S10, the control unit 4 receives the output signals of the hall ICs 513a and 513b (step S13).

The control unit 4 determines the opening and closing of the toilet lid based on the output signals of the hall ICs 513a and 513b (step S14). If it is determined that the toilet lid is closed, the control unit 4 returns to step S13.

In the second embodiment, the opening and closing of the toilet lid is determined on the basis of the output signals of the hall ICs 513a and 513b. The seating sensor 51 which detects the presence or absence of a user may be used.

On the other hand, when it determines with the toilet lid open, the control part 4 transmits a heating instruction to the instantaneous heating apparatus 33 (step S15). As a result, the amount of heat generated from the sheath heater 505 increases.

Moreover, the control part 4 instructs the rotation angle of the switching valve 14a (step S16). 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 rotates, and the washing water at the flow rate Q4 is supplied to the pipe 510 of the instantaneous heating device 33. Then, the hot water for nozzle cleaning heated by the operation of the instantaneous heating device 33 moves from the nozzle cleaning nozzle 3 to the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2. Squirt.

Thereby, the dirt adhering around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2 is lifted off.

Thereafter, the control unit 4 determines whether the predetermined time has elapsed (step S17). The predetermined time in step S17 is time required for jetting the hot water for nozzle cleaning around the jetting hole 25 of the anal nozzle 1a or the jetting hole of the bidet nozzle 2 for cleaning. If the predetermined time has not elapsed, the control unit 4 returns to step S17 and waits 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 increase the heating temperature (step S18). As a result, the amount of heat generated from the sheath heater 505 increases.

Moreover, the control part 4 instructs the rotation angle of the switching valve 14a (step S19). For example, the motor 141 is instructed to set the rotation angle of the switching valve 14a of FIG. 15 to about 110 degrees. Thereby, the motor 141 rotates and the washing | cleaning water supplied to the piping 510 of the instantaneous heating apparatus 33 reduces. Therefore, the hot water for nozzle cleaning changes to the nozzle cleaning steam.

As a result, the hot nozzle cleaning steam is ejected from the nozzle cleaning nozzle 3 around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2. Therefore, various germs and dirts stuck around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2 are removed and sterilized. In addition, the nozzle part 30 in 2nd Example is formed from resin with high heat resistance which does not deform | transform even in the ejection of nozzle cleaning steam or hot water for nozzle cleaning.

Thereafter, the control unit 4 determines whether the predetermined time has elapsed (step S20). The predetermined time in step S20 is a time required for blowing the nozzle cleaning vapor around the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2 to perform 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 an instruction to stop the heating to the instantaneous heating device 33 (step S21). As a result, the power supply to the sheath heater 505 of the instantaneous heating device 33 is stopped.

Subsequently, the control unit 4 determines whether the predetermined time has elapsed (step S22). The predetermined time in step S22 is a time required until the temperature around the blowing hole 25 of the anal nozzle 1a or the blowing hole of the bidet nozzle 2 falls. In addition, since this predetermined time depends on the outside air temperature, it may be set to be variable in correspondence with the season or the like. For example, you may set to 4 to 6 second in summer, and 1 to 3 second 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, the nozzle cleaning steam changes to the nozzle cleaning high temperature water, and the temperature decreases, whereby the low temperature washing water From the instantaneous heating apparatus 33, it blows around the blowing hole 25 of the anal nozzle 1a, or the blowing hole of the bidet nozzle 2 via the nozzle cleaning nozzle 3. As shown in FIG.

As a result, the temperature of the periphery of the blowing hole 25 of the anal nozzle 1a falls gradually. Thereby, since the temperature of the nozzle part 30 after sterilization can be reduced, propagation of various germs can be suppressed.

On the other hand, when a predetermined time has elapsed, the rotation angle of the switching valve 14a is instructed (step S23). For example, the motor 141 is instructed to set the rotation angle of the switching valve 14a of FIG. 15 to about 135 degrees. As a result, the motor 141 rotates, and the washing water supplied to the pipe 510 of the instantaneous heating device 33 stops. As a result, the washing water sprayed from the nozzle washing nozzle 3 stops.

Subsequently, the control unit 4 transmits a lamp lighting control signal for controlling the lighting of the notification lamp 311 of the remote control apparatus 300a (step S24). For example, a pulse lamp lighting control signal composed of a logic high H and a logic low L is transmitted to the notification lamp 311. The notification lamp 311 lights up when it is logic high based on the lamp lighting control signal, and turns off when it is logic low. As a result, the notification lamp 311 blinks.

The control unit 4 also transmits a sound output control signal for controlling the output of sound from the speaker 310 to the speaker 310 of the remote control apparatus 300a (step S25). Thereby, sound is output from the speaker 310 installed in the remote control apparatus 300a. For example, “Nozzle cleaning has been completed” by the control unit 4 from the speaker 310. Please use it with confidence ”, or the sound of“ beep beep ”is repeatedly output.

Subsequently, the controller 4 determines whether the predetermined time has elapsed (step S26). If the control part 4 does not pass predetermined time, it returns to step S24 and repeats the process of step S24 and step S25. The predetermined time in this step S26 is a time for notifying the user that the nozzle cleaning has ended.

On the other hand, when a predetermined time has elapsed, the control unit 4 transmits a lamp extinction control signal for controlling the extinguishing of the notification lamp 311 to the notification lamp 311 (step S27), and at the same time the A sound stop control signal for controlling to stop the output of sound from the speaker 310 is transmitted (step S28). As a result, the notification lamp 311 goes out, and output of sound from the speaker 310 is stopped.

In the sanitary washing apparatus 100a according to the present invention, nozzle cleaning is performed when the sanitary washing apparatus 100a is unused by the seating sensor 51, the hall ICs 513a and 513b, and the toilet seat switch 55. Since the cleaning of the anal nozzle 1a and the bidet nozzle 2 by the nozzle 3 is permitted, the washing water by the nozzle cleaning nozzle 3 is prevented from adhering to the human body when the sanitary washing apparatus is used. As a result, the anal nozzle 1a and the bidet nozzle 2 can be kept clean while providing sufficient security to the user and ensuring safety. In addition, by exposing the anal nozzle 1a and the bidet nozzle 2 to high temperature steam, the dirt adhering to the anal nozzle 1a and the bidet nozzle 2 is easily removed, and a sterilizing effect is obtained. . In addition, the sterilization range at high temperature is expanded by the diffusivity of the steam.

In addition, the anal nozzle 1a and the bidet nozzle 2 are washed with steam or heated washing water and then washed with non-heated washing water, thereby sterilizing the anal nozzle 1a and the bidet with steam or heated washing water. Since the temperature of the nozzle 2 can be reduced, it is possible to prevent the hot washing water from being ejected to the user. Moreover, propagation of various germs can be suppressed.

In addition, the washing water is instantaneously heated by the instantaneous heating device 33 to generate heated washing water or steam, which is ejected from the nozzle cleaning nozzle 3 to the anal nozzle 1a and the bidet nozzle 2. do. As a result, the anal nozzle 1a and the bidet nozzle 2 are cleaned by hot washing water or steam. In addition, steam and heated washing water are ejected from the nozzle washing nozzle 3 by adjusting the flow rate of the washing water supplied to the instantaneous heating device 33. Therefore, the anal nozzle 1a and the bidet nozzle 2 can be wash | cleaned easily by the steam or heated wash water by adjustment of the flow volume of wash water.

In addition, in the remote control device 300a according to the second embodiment, the anal nozzle 1a and the bidet nozzle 2 are moved at an arbitrary time by the operation of the nozzle cleaning switch 309 of the remote control device 300a. In addition to being able to clean, the operability is improved, and the operation of the child lock switch 312 makes the instruction of the start of the cleaning operation of the nozzle cleaning nozzle 3 invalid, thereby preventing mischief and misoperation by the child. Becomes possible. In addition, since the end of the cleaning operation is notified after the cleaning operation by the nozzle cleaning nozzle 3 is finished, the user can recognize that the cleaning operation is continued until the end of the cleaning operation is notified. Accordingly, during the continuation of the cleaning operation, the user ejects the washing water from the wrong anal nozzle 1a and the bidet nozzle 2 and contacts the washing water ejected from the wrong anal nozzle 1a and the bidet nozzle 2. Is prevented. Therefore, the anal nozzle 1a and the bidet nozzle 2 can be kept clean, while ensuring safety.

Next, FIG. 26 is a schematic plan view which shows the other example of the remote control apparatus of FIG.

The remote control device 300b 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 apparatus 300b is provided with the liquid crystal display part 313 instead of the speaker 310 and the notification lamp 311 of the remote control apparatus 300a.

Accordingly, information can be displayed on the liquid crystal display 313 using letters, symbols, graphics, and the like. For example, the character can be displayed on the liquid crystal display 313 as "nozzle sterilization complete". As a result, the user can visually recognize that the nozzle cleaning is completed and the sanitary washing apparatus 100a can be used safely.

A sheath heater 505 is provided in the casing 504a, and both ends of the sheath heater 505 protrude outward from both end surfaces of the casing 504a. A cylindrical space 510a formed between the casing 504a and the sheath heater 505 serves as the pipe 510 of FIG. 16.

In the nozzle cleaning described above, the washing water supplied from the washing water outlet 143e of the switching valve 14 of FIG. 13 is introduced into the cylindrical space 510a through the water supply port 511a.

When electric power is supplied to the sheath heater 505, the washing water flowing through the cylindrical space 510a is heated by the heat generated by the sheath heater 505, and the hot water for nozzle cleaning or the steam for nozzle cleaning is discharged to the outlet 512a. Is discharged from).

In this case, since the piping 510 does not need to be formed like the instantaneous heating apparatus 33 in the instantaneous heating apparatus 33a, cost reduction can be aimed at. In addition, since the sheath heater 505 and the washing water directly exchange heat, the heat exchange rate can be increased.

(Third embodiment)

Hereinafter, the main body 200a of the sanitary washing apparatus 100a according to the third embodiment of the present invention will be described. The sanitary washing apparatus 100a according to the third embodiment is the same as the configuration of the sanitary washing apparatus 100a according to the second embodiment. The operation of the main body 200a of the sanitary washing apparatus 100a according to the third embodiment is different from the operation of the main body 200a of the sanitary washing apparatus 100a according to the second embodiment. .

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

30 shows the time, FIG. 30A shows the timing of the heating apparatus control signal HS, FIG. 30B shows the temperature change of the blowing hole 25 of the anal nozzle 1a, and FIG. 30C shows FIG. The lamp lighting control signal of the notification lamp 311 of the remote control apparatus 300a is shown.

As shown in FIG. 28, first, the control part 4 determines whether the nozzle cleaning operation signal was received from the remote control apparatus 300a (step S30). Here, the nozzle cleaning operation signal is a predetermined signal transmitted to the control unit 4 by the nozzle cleaning switch 309 being pressed.

When the control unit 4 does not receive the nozzle cleaning operation signal from the remote control device 300a, it determines whether or not another signal is received (step S31). When receiving another signal, the control unit 4 performs a predetermined operation based on the other signals (step S32). For example, when the control unit 4 receives a signal from which the anal switch 303 is pressed down from the remote control device 300a, the control unit 4 controls to eject the washing water from the anal nozzle 1a. On the other hand, when no other signal is received in step S31, the control unit 4 returns to step S30.

Next, when receiving the nozzle cleaning operation signal from the remote control device 300a in step S30, the control part 4 receives the output signal of the seating sensor 51 (step S33).

The control part 4 determines the presence or absence of a human body on the toilet seat part 400 based on the output signal of the seating sensor 51 (step S34). If it is determined that the human body exists, the control unit 4 returns to step S33.

On the other hand, when determining that the human body does not exist, the control part 4 transmits a heating instruction to the instantaneous heating apparatus 33 (step S35). As a result, the amount of heat generated from the sheath heater 505 increases. For example, as shown in FIG. 30A, the control part 4 transmits the pulse type heating device control signal HS comprised from the logic high H and the logic low L to the instantaneous heating apparatus 33. As shown in FIG. do. The instantaneous heating device 33 adjusts the on and off of the sheath heater 505 based on the heating device control signal HS.

Moreover, the control part 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 rotates, and the washing water at the flow rate Q4 is supplied to the pipe 510 of the instantaneous heating device 33. Then, the hot water for nozzle cleaning heated by the operation of the instantaneous heating device 33 moves from the nozzle cleaning nozzle 3 to the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2. Squirt.

Thereby, as shown in FIG. 30B, the temperature of the blowing hole 25 of the anal nozzle 1a raises. The dirt adhering around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2 floats and is removed.

Thereafter, the control unit 4 determines whether the predetermined time has elapsed (step S37). The predetermined time in step S37 is time required for jetting the hot water for nozzle cleaning around the jetting hole 25 of the anal nozzle 1a or the jetting hole of the bidet nozzle 2 for cleaning. If the predetermined time has not elapsed, the control unit 4 returns to step S37 and waits until the predetermined time elapses.

On the other hand, when the predetermined time has elapsed, the controller 4 instructs the instantaneous heating device 33 to increase the heating temperature (step S38). As a result, the amount of heat generated from the sheath heater 505 increases.

Moreover, the control part 4 instructs the rotation angle of the switching valve 14a (step S39). For example, the motor 141 is instructed to set the rotation angle of the switching valve 14a of FIG. 15 to about 110 degrees. Thereby, the motor 141 rotates and the washing | cleaning water supplied to the piping 510 of the instantaneous heating apparatus 33 reduces. Therefore, the hot water for nozzle cleaning changes to the nozzle cleaning steam.

As a result, the hot nozzle cleaning steam is ejected from the nozzle cleaning nozzle 3 around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2. Therefore, various germs and dirts stuck around the ejection hole 25 of the anal nozzle 1a or the ejection hole of the bidet nozzle 2 are removed and sterilized. In addition, the nozzle part 30 in 2nd Example is formed from resin with high heat resistance which does not deform | transform even in the ejection of nozzle cleaning steam or hot water for nozzle cleaning.

After that, the controller 4 determines whether the predetermined time has elapsed (step S40). The predetermined time in step S40 is time required for spraying the nozzle cleaning steam around the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2 to perform cleaning and sterilization. If the predetermined time has not elapsed, the controller 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 an instruction to stop the heating to the instantaneous heating device 33 (step S41). As a result, the power supply to the sheath heater 505 of the instantaneous heating device 33 is stopped.

Subsequently, the control unit 4 determines whether the predetermined time has elapsed (step S42). The predetermined time in step S42 is a time required until the temperature around the jet hole 25 of the anal nozzle 1a or the jet hole of the bidet nozzle 2 falls, and in FIG. ) In addition, since this predetermined time depends on the outside air temperature, it may be set to be variable in correspondence with the season or the like. For example, you may set to 4 to 6 second in summer, and 1 to 3 second in winter.

In this case, as shown in FIG. 30B, the temperature of the jet hole 25 of the anal nozzle 1a 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, the nozzle cleaning steam changes to the nozzle cleaning high temperature water, and the temperature decreases, whereby the low temperature washing water From the instantaneous heating apparatus 33, it blows around the blowing hole 25 of the anal nozzle 1a, or the blowing hole of the bidet nozzle 2 via the nozzle cleaning nozzle 3. As shown in FIG.

As a result, the temperature of the periphery of the blowing hole 25 of the anal nozzle 1a falls gradually. Thereby, since the temperature of the nozzle part 30 after sterilization can be reduced, propagation of various germs can be suppressed.

On the other hand, when a predetermined time has elapsed, the rotation angle of the switching valve 14a is instructed (step S43). For example, the motor 141 is instructed to set the rotation angle of the switching valve 14a of FIG. 15 to about 135 degrees. As a result, the motor 141 rotates, and the washing water supplied to the pipe 510 of the instantaneous heating device 33 stops. As a result, the washing water sprayed from the nozzle washing nozzle 3 stops.

Subsequently, the control unit 4 transmits a lamp lighting control signal for controlling the lighting of the notification lamp 311 of the remote control apparatus 300a (step S44). For example, as shown in FIG. 30C, a pulse type lamp lighting control signal composed of a logic high H and a logic low L is transmitted to the notification lamp 311. The notification lamp 311 lights up when it is logic high based on the lamp lighting control signal, and turns off when it is logic low. As a result, the notification lamp 311 blinks.

In addition, the control unit 4 transmits a sound output control signal for controlling the output of sound from the speaker 310 to the speaker 310 of the remote control apparatus 300a (step S45). Thereby, sound is output from the speaker 310 installed in the remote control apparatus 300a. For example, “Nozzle cleaning was completed” from the speaker 310 by the control unit 4. Please use it with confidence. ”The sound is repeated, or the sound of` `beep beep '' is repeatedly output.

Subsequently, the control unit 4 determines whether the predetermined time has elapsed (step S46). If the control part 4 does not pass a predetermined time, it returns to step S44 and repeats the process of step S44 and step S45. The predetermined time in this step S46 is a time for notifying the user that the nozzle cleaning has ended, and corresponds to the time T2 in FIG. 30.

On the other hand, when the predetermined time has elapsed, the control unit 4 transmits a lamp extinction control signal for controlling the extinguishing of the notification lamp 311 to the notification lamp 311 (step S47), and at the same time the A sound stop control signal for controlling to stop the output of sound from the speaker 310 is transmitted (step S48). As a result, the notification lamp 311 goes out, and output of sound from the speaker 310 is stopped.

In the sanitary washing apparatus 100a according to the present invention, the washing operation at the high temperature by the nozzle washing nozzle 3 ends, and after the temperature of the anal nozzle 1a decreases, the end of the washing operation is notified of the notification lamp 311. And the speaker 310, the user can recognize that the cleaning operation at a high temperature continues until the end of the cleaning operation is notified. Accordingly, during the continuation of the cleaning operation at a high temperature, the user ejects the washing water from the wrongly hot anal nozzle 1a and the bidet nozzle 2 and the wrongly hot anal nozzle 1a and the bidet nozzle 2. Contact is prevented. Accordingly, the anal nozzle 1a and the bidet nozzle 2 can be kept clean while providing sufficient security to the user and ensuring safety.

In addition, since the notification lamp 311 and the speaker 310 stop the notification that the cleaning operation has ended after a predetermined time elapses from the end of the cleaning operation by the nozzle cleaning nozzle 3, the notification more than necessary is prevented. , Unnecessary power consumption is prevented. In addition, by using the speaker 310, an elderly person or a user whose eyes are not free can recognize audibly that the washing operation at a high temperature is finished. Therefore, the safety of various users is secured.

In addition, when the anal nozzle 1a and the bidet nozzle 2 are exposed to high temperature steam, the dirt attached to the anal nozzle 1a and the bidet nozzle 2 floats, and the dirt washes with high temperature washing water. Bactericidal effect is obtained. In addition, the sterilization range at high temperature is expanded by the diffusivity of the steam.

In the sanitary washing apparatus of the third embodiment, since the end of the washing operation is notified after the washing operation at the high temperature of the anal nozzle 1a and the bidet nozzle 2 by steam is completed, the washing operation at the high temperature is continued. The user comes into contact with the wrongly hot steam, ejects the washing water from the wrongly heated anal nozzle 1a and the bidet nozzle 2 and the contact with the wrongly heated anal nozzle 1a and the bidet nozzle 2 Is prevented. Therefore, the anal nozzle 1a and the bidet nozzle 2 can be kept clean, while ensuring safety.

Further, 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 into hot washing water or steam. Therefore, by adjusting the flow rate of the washing water, the human washing nozzle device can be easily washed with the washing water having different physical properties.

In addition, by operating the nozzle cleaning switch 309 provided in the remote control device 300a, the anal nozzle 1a and the bidet nozzle 2 can be cleaned at any time, and the operability is improved.

(Example 4)

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

31 is a schematic diagram showing the configuration of the main body 200b of the sanitary washing apparatus 100b according to the fourth embodiment of the present invention.

The main body portion 200b of the sanitary washing apparatus 100b of FIG. 31 further includes a scale preventing substance supply device 34 in the configuration of the main body portion 200a of the sanitary washing apparatus 100a of FIG. 12. The detail of the anti-scaling substance supply apparatus 34 is mentioned later.

32 is a partially cutaway sectional view showing the structure of the instantaneous heating device 33. In FIG. 32, the instantaneous heating device 33 includes a casing 504, a sheath heater 505, a heat conductor 506, a pipe 510, a thermistor 33a, a thermostat 33b, and a thermal fuse 33c. It includes.

The casing 504 has a substantially rectangular parallelepiped shape. In the casing 504, the pipe 510 and the sheath heater 505 are provided at predetermined intervals so as to extend in the longitudinal direction, and both ends protrude outward from both end surfaces of the casing 504. Here, one end side of the pipe 510 is made upstream of the instantaneous heating device 33, and the other end side of the pipe 510 is made downstream of the instantaneous heating device 33. One end of the pipe 501 is connected to a pipe 520 connected to the switching valve 14a of FIG. 31.

The scale prevention substance supply apparatus 34 is interposed in the piping 520 upstream of the instantaneous heating apparatus 33. The anti-scale material supply device 34 contains an anti-scale agent.

In the casing 504, the pipe 510 and the sheath heater 505 are covered with the heat conductor 506. The sheath heater 505 incorporates a heating wire and generates heat by supplying electric power.

In the nozzle cleaning described above, the washing water is introduced into the pipe 510 from the water supply port 511 by the switching valve 14a.

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

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

In the fourth embodiment, the thermistor 33a, the thermostat 33b and the temperature fuse 33c are different from each other in operation reference temperature. Thereby, three steps of overheat prevention can be adjusted. In addition, even if any one of the thermistor 33a, the thermostat 33b, and the thermal fuse 33c breaks down, overheating is prevented by the remaining two.

The thermistor 33a is attached to the sheath heater 505 and detects the temperature of the sheath heater 505. The control unit 4 determines the temperature of the sheath heater 505 supplied from the thermistor 33a, and controls the temperature of the sheath heater 505 to be lowered when it is in an overheated state.

The thermostat 33b is attached so that the temperature of the washing water which flows in the piping 510 can be detected. When the temperature of the washing water flowing in the pipe 510 exceeds the operation reference temperature of the thermostat 33b, the thermostat 33b operates to cut off the power supply of the sheath heater 505.

Finally, the thermal fuse 33c is tightly fixed to the casing 504. When the temperature of the casing 504 exceeds the operating reference temperature of the thermal fuse 33c, the supply of power to the sheath heater 505 is cut off by melting the thermal fuse 33c.

By the operation of the thermistor 33a, the thermostat 33b, and the temperature fuse 33c, the overheating of the washing water by the sheath heater 505 and the overheating of the sheath heater 505 itself are prevented.

In the instantaneous heating device 33 according to the fourth embodiment, the sheath heater 505 is used as the heating device for the washing water, but the present invention is not limited thereto. A mica heater, a ceramic heater, a print heater or the like is used. You may also do it.

In addition, although the thermistor 33a, the thermostat 33b, and the thermal fuse 33c prevent the overheating of the instantaneous heating apparatus 33, respectively, the thermistor 33a or the thermostat 33b is connected with the control part 4; By doing so, the control unit 4 may perform feedback control or feedforward control of the temperature of the sheath heater 505 based on the temperature measurement of the thermistor 33a or the thermostat 33b.

As a scale inhibitor, a phosphoric acid compound, acrylic acid, or an acrylic acid compound can be used. As the phosphate compound, one of calcium phosphate, potassium phosphate, hexam phosphate, tripolyaluminum calcium-phosphate, tripolyaluminum phosphate-magnesium, magnesium pyrrolate, m calcium phosphate, or calcium m sodium phosphate may be used, or You may use 2 or more types of mixtures.

As the acrylic acid compound, an acrylic acid copolymer compound or the like can be used.

Thus, by supplying a phosphoric acid compound, acrylic acid, or an acryl compound to wash water, the crystal form of the scale in wash water changes, and crystal growth is inhibited. Thereby, deposition of a scale is prevented and attachment of the scale to the wall surface of the piping 510 of the instantaneous heating apparatus 33 can be prevented.

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

In addition, a chelate substance may be used as the scale inhibitor. Examples of the chelate substance include ethylenediamine tetraacetic acid, hydroethylethylenediamine triacetic acid, dihydroxyethylenediamine diacetic acid, 1,3-propanediamine tetraacetic acid, triethylenetetramine hexaacetic acid, nitrotylotriacetic acid, gluconic acid and the like. One or two or more of them may be used.

In this case, the scale is removed by the chelating material reacting with the metal ions in the scale. As a result, adhesion of the scale on the wall surface of the pipe 510 of the instantaneous heating device 33 is prevented.

In addition, a scale dissolving agent may be used as the anti-scaling agent. Citric acid, hydrochloric acid, acetic acid, nitric acid, etc. can be used as a scale dissolving agent.

In this case, the scale is dissolved and the scale is removed. Thereby, adhesion of the scale in the wall surface of the piping 510 of the instantaneous heating apparatus 33 is prevented. In addition, unnecessary components other than the scale component are also dissolved by the scale dissolving agent. Thereby, the sodium ions and potassium ions which are unnecessary components can also be removed.

In addition, a heater may be provided in the vicinity of the scale preventing substance supply device 34 and heated. Thereby, reaction of a scale dissolving agent and a scale component is accelerated | stimulated, and the effect of removing a scale becomes high.

As described above, the anti-scale agent is supplied to the washing water supplied to the instantaneous heating device 33 by the anti-scale material supply device 34. Thereby, adhesion of the scale in the wall surface of the piping 510 of the instantaneous heating apparatus 33 is prevented automatically.

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

(Fifth Embodiment)

33 is a schematic perspective view of a part of the sanitary washing apparatus according to the fifth embodiment of the present invention.

33, the sanitary washing apparatus according to the fifth embodiment of the present invention is different from the sanitary washing apparatus 100b according to the fourth embodiment of the present invention. Instead of (34) or in addition to the anti-scale material supply device 34, a vertical magnetic field generating magnet 514a and a horizontal magnetic field generating magnet 514b are provided.

The vertical magnetic field generating magnet 514a generates a vertical magnetic field, and the horizontal magnetic field generating magnet 514b generates a horizontal magnetic field. In addition, the vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b are made of an electromagnet 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 washing water flowing in the pipe 510.

Further, by using both the vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b, it is possible to supplement the inactive range of each magnet. As a result, magnetism can be applied to the whole of the washing water flowing in the pipe 510.

As described above, by applying magnetic force to the washing water flowing in the pipe 510, ion separation is generated in which the ions of the same polarity flow in the pipe 510. In this case, ions are concentrated to promote collision of ions. Thereby, the aggregation and precipitation action of ions is promoted. Therefore, the aggregate of ions flows downstream of the instantaneous heating device 33 without the scale occurring on the wall surface of the pipe 510. Thereby, adhesion of the scale in the wall surface of the piping 510 of the instantaneous heating apparatus 33 is prevented automatically.

In addition, since the vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b operate semi-permanently, maintenance is unnecessary.

The vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b may be provided so as to be rotatable around the outer circumferential surface of the pipe 510 by an actuator (not shown).

The vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b may be reciprocated in the axial direction of the pipe 510. Thereby, ion fractionation can be generated more effectively. Thereby, adhesion of the scale in the wall surface of the piping 510 can be prevented more effectively.

In addition, a permanent magnet may be used as the vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b. In this case, power supply can be made unnecessary.

(Sixth Embodiment)

34 is a schematic diagram of a part of the sanitary washing apparatus according to the sixth embodiment of the present invention.

As shown in FIG. 34, the sanitary washing apparatus according to the sixth embodiment is different from the sanitary washing apparatus 100b of the fourth embodiment in place of the anti-scaling substance supply device 34 to the pipe 510 or the anti-scaling. In addition to the substance supply device 34, an ultrasonic vibrator S is provided.

When an AC voltage having a resonance frequency is supplied to the ultrasonic vibrator S, strong ultrasonic waves are generated by the resonance phenomenon. The ultrasonic waves generated by the ultrasonic vibrator S do not disperse and propagate in a direction perpendicular to the vibrating surface.

Thus, the ultrasonic vibrator S is provided at the refracted portion of the pipe 510 to propagate the ultrasonic waves in the direction of the flow of the washing water. As a result, fine bubbles (hereinafter referred to as cavitation) are generated in the washing water.

Cavitation generated in the washing water by the ultrasonic waves vaporizes carbonate ions in the washing water which is the cause of the scale. Thereby, generation | occurrence | production of a scale is prevented and attachment of a scale in the wall surface of the piping 510 of the instantaneous heating apparatus 33 can be prevented automatically. In addition, since the ultrasonic vibrator S operates semi-permanently, maintenance is unnecessary.

In the above fourth, fifth and sixth embodiments, the anal nozzle 1a 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, The anti-scale material supply device 34 corresponds to the anti-scale agent supply device, the vertical magnetic field generating magnet 514a and the horizontal magnetic field generating magnet 514b correspond to the magnetic generating portion, and the ultrasonic vibrator S is provided in the ultrasonic generating portion. It is considerable.

The temperature sensor 12b measures the temperature of the washing water heated to the predetermined temperature by the heat exchanger 11, and supplies the temperature measurement value to the controller 4. The temperature sensor 12c measures the temperature of the washing water supplied to the nozzle cleaning nozzle 3 via the heat exchanger 11, and supplies the temperature measurement value to the control unit 4.

The pump 13 pumps the washing water heated by the heat exchanger 11 to the switching valve 14a based on the control signal supplied by the control unit 4. The switching valve 14a is cleaned by any one of the anal nozzle 1a, the bidet nozzle 2 and the nozzle cleaning nozzle 3 of the nozzle part 30 based on the control signal supplied by the control part 4.
