Abstract

PURPOSE:To improve comfortableness by performing throwing-away of hot-water until the hot-water temperature reaches a setting temperature, performing throwing-away of hot-water when washing operation is not performed for a specified time after the completion of preparation for washing, and preferentially performing washing operation when washing operation is performed during re-throwing-away of hot-water. CONSTITUTION:The temperature of hot-water supplied from a hot-water supply pipe of a valve unit 2 into a hot-water receiving pipe 2d is detected by a temperature sensor. When the temperature of hot-water is below a setting temperature, a hot-water throwing-away solenoid valve 7a is opened to discharge hot-water through a hot-water discharge pipe 2e to an outside hot-water throwing-away pipe. When a specified time elapses without performing washing operation after the hot-water temperature rises above the setting temperature and preparation for washing is completed, the throwing-away of hot-water is performed again. Further, when a user performs washing operation during the re-throwing- away of hot-water, a water-discharge solenoid valve 7b is opened to spout out hot-water from an expansion nozzle 3c of a nozzle device 3.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device having a private part cleaning function.
In particular, the present invention relates to means for prioritizing cleaning operations during retesting of hot water.

[Conventional technology]

2. Description of the Related Art Hitherto, sanitary washing devices that spray heated washing water onto private parts for washing have been used either integrally with a toilet bowl or as a separate type. As an example of integrating it into a toilet bowl, for example,
There are those described in Japanese Patent Publication No. 2-15689 and Japanese Patent Publication No. 6326207, and various other structures have already been developed.

In these sanitary cleaning devices, the basic structure of the reservoir for private parts cleaning is that a nozzle that moves forward and backward from the inside of the casing integrated into the toilet bowl to the cleaning position is provided, and is also equipped with a heating tank, etc. that supplies hot water to this nozzle. . This type of structure has been adopted in most conventional sanitary cleaning devices, and advances are being made to optimize the cleaning position by appropriately controlling the temperature of hot water and changing the stroke of the nozzle.

Conventional sanitary cleaning equipment consumes a lot of power because it includes a hot water tank with a built-in heater to heat the hot water, a motor to drive the nozzle, etc., and requires handling as an electrical device that uses a general commercial power source. On the other hand, when a toilet is integrated with a washbasin or bathtub, such as in a unit bath, the degree of exposure to water is large, so the structure of the sanitary cleaning device must be particularly strengthened to prevent electrical leakage and electric shock. It won't happen.

To solve this problem, since a hot water supply facility is connected to the unit bath, an external water supply source and hot water supply source can be connected to the nozzle device. Therefore, if the supplied water and hot water are appropriately mixed and discharged, there is no need to provide a hot water tank, and there is no need to supply electricity to the heater. Therefore, the current consumption and power consumption are small (to some extent), and it is effective to some extent as a measure to prevent electrical leakage and electric shock.

By the way, in a sanitary cleaning device that mixes hot water using an external water supply source and a hot water source, when cleaning private parts, the water in the hot water pipe connected to the hot water source is initially cold, It is not suitable for spraying on private parts as washing water. Once the water in the hot water supply pipe has been allowed to flow to a certain extent, hot water will be supplied from the main water supply pipe. Therefore, until hot water is supplied from the hot water supply pipe, a hot water waste operation is required to discharge the low temperature water remaining in the hot water supply pipe to the outside from the waste water pipe.

During this dumping operation, that is, while water that does not reach a predetermined temperature is being supplied from the hot water supply pipe, it is not preferable to discharge water from the cleaning nozzle because water that feels cold will be sprayed locally. Therefore, control is performed to stop the cleaning operation during that time. Then, when the temperature of the hot water supplied from the hot water supply pipe reaches a predetermined temperature, the discharging of hot water is stopped and the cleaning operation becomes possible.

In this way, consideration is taken to prevent the cold water in the hot water supply pipe from being sprayed locally.

Situations where this waste hot water is required are not only in the initial state when the user is sitting on the toilet seat, but also when the water supply pipe cools down and the temperature of the hot water decreases after the user is seated and the user is not able to perform the cleaning operation for a while. It also occurs when the temperature cannot be maintained at an appropriate temperature. Even in such cases, it is preferable to detect the hot water temperature and re-test the hot water until it reaches an appropriate temperature for comfortable use.

[Problem to be solved by the invention]

In this retesting operation, as with the initial discarding operation, the idea is that cleaning operations are not possible until the water temperature reaches a predetermined temperature, that is, the idea is to treat the retesting hot water and the initial discarded hot water without making a distinction. is normal.

The present invention focuses on the fact that the initial discarded hot water and the re-inspection of hot water are in different situations even in the same disposal area, and by prioritizing the cleaning operation during the re-inspection of the hot water, it eliminates the waiting time for the user and maintains the temperature at an appropriate temperature. The purpose is to provide a comfortable feeling to the user by jetting hot water close to that of water as cleaning water.

[Means to solve the problem]

In order to achieve the above objectives, the sanitary cleaning device of the present invention has the following features:
In a sanitary cleaning device that mixes water and hot water supplied from an external water supply pipe and a hot water supply pipe at a ratio to reach a set temperature and sprays hot water to a private area from a cleaning nozzle, the temperature of the hot water supplied from the hot water supply pipe is detected. temperature detection means for discharging the detected hot water to the outside from a wastewater pipe until the temperature of the detected hot water reaches a set temperature, and disabling cleaning operations during that time; As described above, the present invention includes a re-inspection means for discharging hot water when the cleaning operation is not performed, and a means for receiving the cleaning operation with priority and performing the cleaning operation when the cleaning operation is performed during the re-inspection. It is characterized by

[Effect]

The reason for the initial hot water discharging operation in sanitary washing equipment is that the remaining water in the hot water supply pipes has cooled to about room temperature, and even after hot water supply starts, the water in the pipes is not suitable as cleaning water until it turns into hot water. This is done by

Therefore, it is necessary to disable the injection of cleaning water during the initial hot water discharging operation in order to prevent the user from feeling uncomfortable.

On the other hand, re-testing is to compensate for the gradual drop in water temperature in the pipes due to the lack of cleaning operations, after the hot water in the hot water supply pipes has reached a predetermined temperature and cleaning operations are possible. It will be held on. This decrease in temperature occurs gradually, so
Within a predetermined period of time, only an acceptable temperature drop occurs.

Therefore, in the present invention, re-t&? If a cleaning operation is performed during the A operation, priority is given to that cleaning operation so that cleaning water can be sprayed. As a result, the user is not given the unpleasant feeling of having to wait until the washing becomes possible because the washing becomes impossible after the washing preparation state is reached, and the user can use the washing machine comfortably.

〔Example〕

Hereinafter, features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 is a circuit diagram showing a configuration example of a control system of a sanitary cleaning device according to the present invention, and FIG. 2 is a flow chart showing the operation of the present invention.

Before explaining the present invention in detail, the basic configuration will be explained.

FIG. 4 is an internal plan view of a sanitary cleaning device showing one embodiment of the present invention.

The sanitary cleaning device has various devices built into its casing 1, and these devices are fixed to a mounting board 1a. Figure 5 shows the installation status of the bath IW A.
In a unit bath integrally equipped with a washbasin B, a casing 1 is fixed to a toilet main body C disposed in front of the washbasin B.

Returning to FIG. 4, the mounting board 1a has a valve unit 2. connected to an external water supply source and hot water supply source. Nozzle device that spouts cleaning water3. Operation unit 4 that operates these devices. A power supply unit (dry battery in this embodiment) 5 and a control circuit board 6 provided for driving the control system are fixed.

The valve unit 2 has an external water supply pipe 2a and a hot water supply pipe 2b.
It is equipped with a water inlet pipe 2C and a hot water inlet pipe 2d which are connected to the water inlet pipe 2C, and a built-in thermostatic mixing valve with an automatic temperature control function. Further, a waste water solenoid valve 7a is provided in the flow path from the hot water inlet pipe 2d to the thermostatic mixing valve, and a water discharge solenoid valve 7b is installed downstream. FIG. 6 shows a water flow system, with a constant flow valve 7c downstream of the water discharge solenoid valve 7b.

A vacuum breaker 7d and a distribution valve 7e are provided, and the distribution valve 7e distributes water to the nozzle installation 3 side and the waste water side. Further, a waste water discharge pipe 2e is connected to the waste water solenoid valve 7a, and this is connected to an external waste water pipe 2f.

The waste water solenoid valve 7a is provided to stir the cold water in the hot water supply pipe 2b and the hot water intake pipe 2d, and the temperature of the hot water is detected by a temperature sensor (a waste water thermistor THE to be described later) disposed upstream thereof. , if the temperature is below a certain temperature, the waste solenoid valve 7a
control to open and drain hot water. In addition, distribution valve 7
A nozzle side hot water pipe 7f is connected to e, and hot water is supplied to the nozzle device 3 side and simultaneously discharged to the pole of the toilet main body C. In this way, the purpose of discharging hot water from the distribution valve 7e is to ensure a sufficient flow rate, since in a thermostatic mixing valve, the temperature sensing part will not operate properly unless the flow rate per unit time is above a certain level. It is. In other words, the temperature sensing part of the thermostatic mixing valve is insufficient to operate with only the flow rate required for private cleaning.
The flow rate is increased to compensate for this. In addition, an overflow pipe 7g is connected to the vacuum breaker 7d,
Overflow water is discharged to the bowl of the toilet main body C in the same way as the nozzle side waste water pipe 7f.

The distribution valve 7e has a needle valve structure, and the flow area of each of the nozzle-side drain pipe 7f and the supply pipe 3a to the nozzle device 3 is changed simultaneously by movement of the valve shaft. This operation is performed by a water force adjustment knob 4a provided in the operating section unit 4, and a flexible shaft 4b using a wire or the like for transmitting rotational operating force is provided between the valve shaft of the distribution valve 7e.

Note that when moving the valve stem using the water force adjustment knob 4a, if the flow rate on the nozzle device 3 side is reduced, the flow rate on the nozzle side waste water pipe 7' side will increase, and conversely, if the flow rate on the nozzle device 3 side is increased, the flow rate on the waste water pipe side will increase. The principle is to provide the distribution valve 7e with a valve structure that reduces the flow rate of the hot water.As a result, a certain amount of hot water is discharged from the valve unit 2, the thermostatic mixing valve operates without any trouble, and the comfortable temperature is maintained. of cleaning water can be sent to the nozzle device 3.

7 and 8 are cross-sectional views showing the nozzle device 3. FIG.

The nozzle device 3 is a cylinder 3 with a supply pipe 3a connected to its upper end.
b and a telescopic nozzle 3C, and has a configuration in which the telescopic nozzle 3C is advanced to the cleaning position by the water pressure of the cleaning water flowing in from the supply pipe 3a. A piston portion 3d is formed at the upper end of the telescopic nozzle 3C, an internal flow path 3e is provided toward the tip, and an ejection hole 3f is formed at the tip j. Further, a coil spring 3g is provided on the tip side of the piston portion 3d and the cylinder 3b, and when the water pressure decreases, the extensible nozzle 3C can be moved in the storage direction by its biasing force.

In such a configuration, when cleaning water is fed into the cylinder 3b from the supply pipe 3a, the piston portion 3d receives it and the telescopic nozzle 3C advances as shown in FIG. At the same time as this advancing operation, the cleaning water from the internal flow path 3e is jetted from the jetting hole 3f, so that private parts can be cleaned. Further, after the supply of cleaning water is stopped, the water pressure decreases, so the extensible nozzle 3C is housed in the cylinder 3b by the biasing force of the coil spring 3g, as shown in FIG. 8.

Further, the cylinder 3b is supported by the frame 8 in order to move the cylinder 3b forward so that the position of the ejection hole 3f of the nozzle device 3 can be changed so that it can be used for anal cleansing and a bidet. As shown in FIG. 9, the frame 8 is provided with an arcuate posture change guide 8a on the back side and a holding guide 8b on the front end side.

The posture change guide 8a receives a bifurcated support arm 3h provided on the lower surface of the cylinder 3b, and the -blade holding guide 8b slidably holds pins 31 provided on the left and right sides of the cylinder 3b. When the cylinder 3b is pulled out to the front by these guides, the cylinder 3b moves forward with a smaller inclination than in the retracted position, as shown by the dashed line in FIG.

The above-mentioned advancing operation of the cylinder 3b is performed by a rotary shaft 9 that is rotatably mounted on the frame 8 and a link rod 9a that is fixed to the rotary shaft 9 and whose tip is connected to the cylinder 3C. FIG. 10(a) is a plan view schematically showing the rotating shaft 9 and its attached mechanism, and FIG. -1 line arrow sectional view. As shown in the figure, one end of the rotating shaft 9 is inserted into a sleeve 8C of the frame 8, and an arm 9b with an engaging pin 9C is fixed to the end. Further, a coil spring 8d is provided around the sleeve 8C, and both ends of the coil spring 8d in the winding direction are engaged with an engaging pin 9C and a restraining pin 8e provided on the frame 8, as shown in FIG. For this reason, in FIG. 10(b), the rotating shaft 9
When the coil spring 8d is rotated clockwise, the coil spring 8d is tightened by the movement of the engagement pin 9C, and an elastic reaction force is generated in the counterclockwise direction. Therefore, if the rotating shaft 9 is released, the rotating shaft 9 will return to its original position due to the restoring force of the coil spring 8d.

Rotation of the rotating shaft 9 is performed by a switching knob 10 provided on the operating unit 4 and a wire 11 connecting the switching knob 10 and the rotating shaft 9. FIG. 11 is a vertical cross-sectional view of the operating section unit 4, in which a boot I is attached to the lower end of the shaft 10a of the switching knob 10.
J10b is provided, and a wire 11 is attached to this wire 11 so that it can be wound up and released. On the other hand, a boo U9d around which the wire 11 can be wound is also fixed to the rotating shaft 9, and a guide boo IJ1 for guiding the wire 11 from the switching knob 10 to the rotating shaft 9 is fixed as shown in FIG.
2 and 13 are rotatably provided on the mounting board 1a.

In FIG. 7, if the winding direction of the wire 11 is such that when the switching knob 10 is rotated clockwise from the neutral position, the wire 11 is pulled, then in FIG. Rotate. Therefore, the cylinder 3C is moved forward by the rotating shaft 9 and the link rod 9a, and can be set to the position shown by the dashed line in FIG.

The guide pulley 12 is rotatably attached to a fixed shaft 12a, as shown in FIG. 12, and the fixed shaft 12a is fixed to the mounting board 1a by a fixing fitting 12b. If the fixing fitting 12b is made movable by drilling a long hole 12c in the fixing fitting 12b and fixing it with a screw 12, the position of the guide boot 2 can be changed and the tension of the wire 11 can be set appropriately. Moreover, if the holding plate 12e is provided along the circumferential surface of the guide pulley 12, even if the wire 11 becomes slack, it will not come off the guide groove of the guide pulley 12. It is oil-free to provide such a configuration to the other guide pulley 13 as well.

Figures 13(a) and (b) are respectively shown in Figure 11.
It is a sectional view taken along the line and the arrow I-III.

The shaft 10a of the switching knob 10 is provided with a holding mechanism for holding the switching knob 10 in the neutral, anal cleaning, and bidet positions, respectively. As shown in FIG. 13(a), this holding mechanism holds the casing 1 against the restraint cam 14a formed on the shaft 10a.
A spring 14b built into the sleeve IC provided on the inner fixed seat 1h and a ball 14C biased by the spring 14b are provided. Further, the biasing force of the spring 14b can be appropriately set by an adjustment screw 14d screwed into the sleeve 1b. With such a holding mechanism, the first
When the shaft 10a is rotated counterclockwise as shown in FIG. 3(C), it is held by the abutting engagement between the restraining cam 14a and the ball 14c, and rotates counterclockwise as shown in FIG. 13(e). The same holds true when the In Fig. 13, (a) is the neutral position, and when the shaft 10a is rotated 90 degrees counterclockwise, it is set to the anus cleaning position, and when it is rotated 90 degrees clockwise, it is set to the bidet position. Ru.

Also, a cam portion 1 is attached to the shaft 10a as shown in FIG. 13('b).
5a is formed, and a micro switch I6 is formed on the fixed seat IC.
is provided. The transfer element 16b of the swing arm 16a provided in the microswitch 16 is arranged to face the circumferential surface of the cam portion 15a, and as the transfer element 16b abuts as it rotates, the swing arm 16a operates. input the signal to the control system. FIG. 13(b) shows the case of the neutral position, where the transfer element 16b is away from the cam portion 15a, and there is no human power to the control system. FIG. 13(d) shows the case of the anus cleaning position, where the transfer element 16b hits the cam portion 15a, the swinging arm 16a operates, a signal is manually input to the control system, and the anus is cleaned. Further, FIG. 13(f) shows the bidet position, and a signal is inputted to the control system by the microswitch 16 as in the case of anal cleaning. Here, the wire 11 is wired so that it has an appropriate tension when it is in the neutral position, so that it is warm when it is in the anus position, and on the contrary, tension is applied when it is in the bidet position.

In the above configuration, when the switching knob 10 is rotated toward the anus cleaning side, the shaft 10a is rotated as shown in FIGS.
rotates and is held in place by a retention mechanism including ball 14c. At the same time, the microswitch 16 is turned on and the signal is inputted to the control section of the control circuit board 6. As a result, the water discharging electromagnetic valve 7b is opened, and hot water appropriately mixed by the thermostatic mixing valve is sent to the nozzle device 3. On the other hand, the shaft 10a is the first
When rotating counterclockwise in Figure 3, the wire 11
is in the direction of loosening, so no acting force to rotate the rotating shaft 9 is generated.

Therefore, the cylinder 3b of the nozzle device 3 remains in the state shown in FIG. 8, and only the telescopic nozzle 3c advances to the position shown by the solid line in FIG. 7 by the water pressure of the supplied washing water. Following this advancement, cleansing water is jetted from the jet hole 3f to perform anal cleansing.

When the cleaning is finished, the microswitch 16 is turned off by returning the switching knob 10 to the neutral position, and the water discharging solenoid valve 7b is closed by a manual signal to the control system. As a result, the water pressure supplied to the nozzle device 3 decreases, and the elastic nozzle 3C is moved to the eighth position by the restoring force of the built-in coil spring 3g.
It is housed in the cylinder 3b as shown in the figure.

On the other hand, when switching to the bidet ff1lJ and rotating the knob]O, the wire 11 is wound up on the pulley 10b, thereby causing the
In Figure (b), the boo IJ9d starts rotating clockwise.

Therefore, the rotating shaft 9 also rotates together, and the cylinder 3b is pushed forward by the link rod 9a.

The cylinder 3b is guided by the arc-shaped posture change guide 8a and the holding guide 8b, and assumes the posture shown by the dashed line in FIG. That is, compared to the cylinder 3b in the storage position, the inclination is smaller and the cylinder 3b is moved forward. At the same time as such a change in the position of the cylinder 3b, the waste water solenoid valve 7a and the water spouting solenoid valve 7 are turned on, as in the case of anal cleansing.
Cleaning water is supplied into the cylinder 3b by opening the valve b.
The telescopic nozzle 3C advances from the 7 cylinder 3b. and,
The supplied irrigating water is lower than the casing 1 than in the case of anal irrigation.
It can be used as a bidet by spraying water at a distance.

When the switching knob 10 is returned to the neutral position after the cleaning is completed, the supply of cleaning water is stopped and the telescopic nozzle 3C is housed in the cylinder 3b as in the case of anal cleaning.

On the other hand, there is no longer any tension on wire 11, so Boo 1J
The restraining force on 9d also becomes zero. Therefore, due to the restoring force of the coiba spring 8d, the rotating shaft 9 rotates counterclockwise in FIG.

As described above, by using the wire 11, the cleaning points of the nozzle device can be set at two locations, and the nozzle device can be conveniently used for anal cleaning and bidet use in the same way as when driven by a conventional electric motor or the like. In addition, there will be less electrical equipment such as electric motors, so
It can be used safely even when deployed in a unit bus.

Next, an embodiment of the present invention shown in FIG. 1 will be described.

In the figure, IcI is a central processing unit, and a thermistor TI (1) detects the temperature of waste water, a thermistor TH2 detects the temperature of discharged water, a waste water solenoid valve 7a based on input signals from the seating switch 5llI and the microswitch 16. It has a function of controlling the operation of the latching solenoid LSI, the latching solenoid LS2 of the water discharge solenoid valve 7b, and the display LED.

That is, when a person sits on the toilet seat, the contact point of the seat switch SW closes due to the weight of the person. Then, the ICI outputs a low level output to the cold open terminal. After that, the output of the cold opening terminal becomes high level after a certain period of time, that is, a sufficient time for the waste water solenoid valve 7a to turn on, and after that, the waste water solenoid valve 7a is held in the open state by the self-holding function. . Also, T
The H Tr terminal continues to output a low level output at regular intervals while a person is sitting. When the cold open terminal becomes low level, transistors Tr 2 , Tr 8 and Tr 9 are turned on. Other transistors Tr l and Tr 7
, TrlO remain off. As a result, current flows through the latching solenoid LSI of the disposal solenoid valve 7a from the upper side to the lower side in the drawing, and the latching solenoid LSI
SI is biased in the opening direction. Then, the waste water solenoid valve 7a
is opened, and the discharging of hot water to the discarded hot water discharge pipe 2e is started. Said T
When the Tr terminal for ll becomes low level, the transistor T
r6 turns on, and the TH1 and TlI2 terminals have
The temperatures of the waste water and the discharge water detected by the waste water thermistor TH1 and the discharge water thermistor T)12 are respectively input.

When the waste water temperature detected by the waste water thermistor THI reaches a predetermined temperature, the output of the cold open terminal becomes low level. The output of the inspection terminal becomes high level after a certain period of time, that is, a sufficient time for the waste water solenoid valve 7a to turn off, and thereafter the waste water solenoid valve 7a is held in a closed state by a self-holding function. Therefore, when the output of the censor terminal becomes low level, the transistors Tr1, Tr7, and TrlO are turned on, and a current flows through the latching solenoid LSI of the waste water solenoid valve 7a from the bottom to the top in the drawing, and the latching solenoid LSI is turned on. Forces the LSI in the closing direction. Then,
The disposal area solenoid valve 7a is closed, and the disposal of hot water to the disposal pipe 2e is stopped.

During this time, the display LED will flash, as shown in Figure 12.
The "Preparing" display on the operating section of the cleaning device flashes to indicate to the user that the water temperature has not reached the water discharge temperature.

The display will stop when the temperature of the thermistor Tl1l rises to a predetermined temperature and the dumping area stops.

The central processing unit 1cI is equipped with a timer function so that the hot water is re-tested every predetermined period of time, for example, 5 minutes after the initial hot water draining operation is completed.

The initial hot water operation and re-inspection area operation are performed by the central processing unit ff1.
Control is performed by C1 based on the flowchart shown in FIG. That is, after the seat switch Sl+ is turned on by the user sitting on the toilet seat, the switching knob 10 is changed from "stop" to "butt" or "bidet" as shown in FIG.
When turned to close the contacts of the microswitch 16 mentioned above. This starts the flow chart of FIG. The central processing unit ICI determines whether or not the draining operation is in progress, and if not, determines whether cleaning preparations have been completed. This is a condition for stopping the initial hot water discharging operation after a predetermined period of time has passed, and the temperature of the hot water supplied from the hot water supply pipe does not rise and cleaning preparations cannot be completed in order to save water. It means excluding. When cleaning preparations are complete, water is discharged M A
Open the I&L child valve and perform the cleaning operation according to the procedure described above. In the above step, if the dumping operation is in progress, it is determined whether it is a re-inspection operation. When the hot water is being retested, the water discharging electromagnetic valve 7b is opened to immediately start the cleaning operation. If the re-inspection site is not in operation, that is, if the initial hot water discharging operation is in progress, the water spouting operation is disabled.

In this way, the cleaning imitation during the re-examination of the hot water is immediately accepted, and the cleaning operation is performed. The temperature of the hot water used during this re-inspection may be slightly lukewarm, but since the re-inspection operation is performed at predetermined intervals, for example every 5 minutes, the temperature of the hot water will drop only slightly during that time, and it will be cold. The temperature never drops to the point where you feel it. The repeat time for re-examination can also be set differently depending on the region.

Next, when discharging water to private parts, turn the switching knob 10 to the third position.
As shown in the diagram, from the "stop" position, press "butt" or "
Turn the bidet to any desired position.

When the switching knob 10 is switched to either position, as described above, the nozzle device i! 3 switches to the "private cleaning" or "bidet" position, and the switching knob ■0 axis 10
The microswitch 16 operates in conjunction with the cam portion 15a provided at the central processing unit +c shown in FIG.
Set the output of furrow terminal 1 to low level. The output of the furrow terminal becomes a high level after a certain period of time, that is, a sufficient time for the water discharge solenoid valve 7b to turn on, and the self-holding function holds the water discharge solenoid valve 7b in an open state. Therefore, when the output of the furrow terminal becomes low level, the transistor Tr
4, Tr12 and Tr[ are turned on. The other transistors Tr3, Trll, and Tr14 remain off. As a result, current flows through the latching solenoid LS2 of the water discharge solenoid valve 7b from the upper side to the lower side in the drawing.
The rafting tournoid LS2 is biased in the opening direction. Then, the water spouting electromagnetic valve 7b opens, supplies cleaning water to the cylinder 3b, advances the telescopic nozzle 3C, and injects the cleaning water to the private parts from its tip.

When cleaning is completed, the switching knob 10 is returned to the "stop" position.

Then, the microswitch 16 is turned off, and the output of the discharge opening terminal of the central processing unit ICI becomes low level.

The output of the discharge opening terminal is maintained for a certain period of time, that is, the discharge solenoid valve 7b
becomes high level after enough time has passed for it to turn off,
Thereafter, the water discharging electromagnetic valve 7b is maintained in a closed state by a self-holding function. Therefore, when the output of the discharge open terminal becomes low level,
The transistors Tr 3 , Trll, and Tr14 are turned on, and a current flows through the luffing tolenoid LS2 of the water discharge solenoid valve 7b from the bottom to the top in the drawing, urging the luffing tolenoid LS2 in the closing direction. Then,
The water discharge electromagnetic valve 7b is closed, and the injection of cleaning water from the telescopic nozzle 3C is stopped.

As mentioned above, the temperature of the cleaning water is physically controlled by the thermostatic mixing valve, but in the unlikely event that the control is not performed correctly, this is to prevent the cleaning water from rising to a temperature that feels hot to the human body. In this case, a water discharge thermistor TH2 is used.

That is, when the water discharge thermistor TH2 senses a temperature higher than a predetermined temperature, the output of the discharge open terminal is set to a low level, and the output of the furrow terminal is set to a low level so that the output does not become a low level.
Performs locking operation. Adding such safety devices prevents accidents such as burns that must be avoided at all costs.

Further, in FIG. 1, IC2 is an element for making the voltage of the dry cell battery constant, and C3 is an element for monitoring the power supply voltage.

〔Effect of the invention〕

As explained above, the sanitary cleaning device of the present invention does not accept a cleaning operation during the initial hot water discharging operation, but accepts a cleaning operation during the retesting operation and performs the cleaning operation immediately. . As a result, even if it may be slightly lukewarm, it is possible to perform washing using warm water at an acceptable temperature, thereby eliminating the discomfort caused by waiting for a while and allowing comfortable use.
