Abstract

PURPOSE:To ensure opening movement of a self-holding type solenoid valve by causing a command to close the solenoid valve to be outputted again each time a seat switch becomes off, even while a control handle is in a discharge stopping position. CONSTITUTION:When washing is finished and a switch handle is reset to the 'off' position, a microswitch 16 becomes off and the output of the discharge closing terminal of a central processing unit IC 1 becomes low level. Then transistors Tr3, Tr11, Tr14 are switched on and a latching solenoid LS2 is energized in its closing direction and a water discharge solenoid valve 7b is closed to stop wash water being jetted from an expansion nozzle 3c. If by some reasons the solenoid valve 7b is not closed even with energization in the closing direction, the processing unit IC1 decides whether or not water is being discharged when a seat switch SW becomes off, and if the water is discharged the unit IC1 outputs a closing signal to the solenoid LS2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power-saving sanitary washing device in which water discharge is controlled by a self-holding electromagnetic valve, and particularly to means for stabilizing the operation of the electromagnetic valve.

[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 Publications No. 2-15689 and Japanese Patent Publication No. 63-26207, and various other structures have already been developed.

The basic structure of these sanitary cleaning devices for private cleaning includes a nozzle that moves forward and backward from the inside of the casing that is integrated into the toilet bowl to the cleaning position, as well as a heating tank that supplies hot water to this nozzle. It is something. 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 also reduced, and this is effective to some extent as a measure to prevent electrical leakage, electric shock, and the like.

Furthermore, if a self-holding type solenoid such as a latching solenoid is used as the solenoid valve that controls the spouting of hot water supplied to the nozzle device, the opening and closing of the valve can be controlled by simply passing current only when the solenoid valve is opened and closed. Therefore, it is possible to save power.

[Problem to be solved by the invention]

In a normal solenoid valve, which operates depending on the presence or absence of electricity, when voltage is applied, the movable core is attracted and the valve opens, and when the voltage is removed, the movable core returns and the valve closes. Therefore, the opening and closing operations of the valve are relatively reliable.

However, in a self-holding type solenoid valve, when the current to open the solenoid valve is passed through the coil, the movable core is attracted, and this state is maintained by the holding force of the permanent magnet, so the current is stopped and the current is turned off. The valve also remains open. therefore,
When a self-holding solenoid valve is used to control water discharge, water is discharged from the wash water.

Next, when a current is passed in the opposite direction to the coil by performing a cleaning stop operation, the electromagnetic force overcomes the attraction force of the permanent magnet and moves the movable iron core to the valve closing position. The current is set to stop after a short period of time set to be sufficient for movement. Then, the water spouting operation stops.

However, if the valve closing operation by the control circuit fails for some reason, the solenoid valve will remain open and the water spouting operation will continue. When such a situation occurs, the water discharging from the cleaning nozzle is not stopped, resulting in inconveniences such as wetting the human body and clothes, and making the floor wet.

The present invention has been made in view of these problems, and an object of the present invention is to ensure the valve closing operation of a self-holding electromagnetic valve.

[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 uses a self-holding electromagnetic valve to control the spouting of washing water from a washing nozzle to a private area, a command to close the self-holding electromagnetic valve can be issued even when the operating knob is in the water spouting stop position. The invention is characterized in that it includes a means for outputting again when it is turned off.

〔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 an example of the configuration of a control system of a sanitary cleaning device according to 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 situation; in a unit bath equipped with bathtub A and washbasin B, washbasin B
A casing 1 is fixed to a toilet main body C placed in front of the toilet bowl.

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 device 3 side and the waste water side. Further, a waste water discharge pipe 2e is connected to the waste water electromagnetic valve 7a, and this is connected to an external hot water pipe 2f.

The disposal solenoid valve 7a is provided to discard the cold water in the hot water supply pipe 2b and the hot water intake pipe 2d, and detects the temperature of the hot water by a temperature sensor (disposal hot water thermistor TH, described later) disposed upstream thereof. , if the temperature is below a certain temperature, the waste water solenoid valve 7a
control to open and drain hot water. In addition, distribution valve 7
A nozzle-side disposal pipe 7f is connected to e, and hot water is supplied to the nozzle device 3 side and simultaneously discharged to the bowl 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 area of each flow path to the nozzle-side disposal 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 unit 4, and a flexible shaft 4b using a flexible 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, reducing the flow rate on the nozzle device 3 side increases the flow rate on the nozzle side hris pipe 7f side, and conversely, increasing the flow rate on the nozzle device 3 side increases the flow rate on the waste water side. It is oil-free to provide the distribution valve 7e with a valve structure that reduces the flow rate. As a result, a certain amount of hot water is discharged from the valve unit 2,
The thermostatic mixing valve operates without any problem, and cleaning water at a comfortable temperature 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 telescoping nozzle 3C, and an internal flow path 3e is provided toward the tip, and an ejection hole 3F is formed at the tip.

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 -force holding guide 8b slidably holds the bins 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 3b. FIG. 10(a) is a plan view schematically showing the rotating shaft 9 and its attached mechanism, and FIG. 10(a) is a sectional view taken along the line I--I in FIG. 10(a). 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 engagement 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 engagement pin 9C and a restraining pin 8e provided on the frame 8, as shown in FIG. 10(b). For this reason, in Fig. 10 et al.), 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.

The image rotated 90 times about the rotation axis is performed by a switching knob lO provided in the operating unit 4 and a wire 11 connecting this and the rotation axis 9. FIG. 11 is a vertical cross-sectional view of the operating unit 4, in which a pulley 10b is provided at the lower end of the shaft 10a of the switching knob 10, and a wire 1 is connected to the pulley 10b.
1 is attached so that it can be rolled up and released. On the other hand, a pulley 9d around which a wire 11 can be wound is also fixed to the rotating shaft 9, and as shown in FIG.
A guide boo U12 for guiding the wire 11 up to U12.
13 is rotatably provided on the mounting board 1a. If the winding direction of the wire 11 is such that the wire 11 is pulled when the switching knob 10 is rotated clockwise from the neutral position in FIG. 7, the pulley 9d will rotate clockwise in FIG. 9(b). do. Therefore, the cylinder 3b 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 12d, the position of the guide pulley 12 can be changed.
The tension of the wire 11 can be set appropriately. Furthermore, if a holding plate 12e is provided along the circumferential surface of the guide boot 2, 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.

FIGS. 13(a) and 13(a) are cross-sectional views taken along the line ■--■ and the line ■--■ in FIG. 11, respectively.

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 a sleeve lc provided on the inner fixed seat 1b 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). It is also maintained in the same way when 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.

Further, a cam portion 15 is formed on the shaft 10a as shown in FIG. 13, and a microswitch 16 is provided on the fixed seat IC. Swing arm 16 provided on micro switch 16
The transfer element 16b of a is arranged to face the circumferential surface of the cam portion 15, and as it rotates, the transfer element 16b abuts and operates the swing arm 16a, and a signal at this time is input to the control system. Figure 13('b) shows the case of the neutral position, where the transfer child 1
6b is away from the cam portion 15, and there is no human power to the control system. FIG. 13(A) shows the case of the anus cleaning position, where the transfer element 16b hits the cam portion 15, the swinging arm 16a operates, a signal is 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, and is loosened when it is in the anus position.
Conversely, when in the bidet position, tension should be applied.

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 the switching knob 10 is turned to the bidet side, the wire 11
is wound around the pulley 10b, thereby causing the
The pulley 9d starts rotating clockwise. Therefore, the rotating shaft 9 also rotates as a unit, and the link rod 9a
Push the cylinder 3b forward. 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 retracted position, the inclination is smaller and the cylinder 3b is advanced forward. Simultaneously with such a change in the position of the cylinder 3b, cleaning water is supplied into the cylinder 3b by opening the water spouting electromagnetic valve 7b, as in the case of anal cleaning, and the telescopic nozzle 3C advances from the cylinder 3b. The supplied washing water is sprayed at a position farther away from the casing 1 than in the case of anal washing, so that it can function as a bidet.

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. - side, wire 11
Since there is no longer any tension on the pulley 9d, the restraining force on the pulley 9d also becomes zero. Therefore, due to the restoring force of the coil spring 8d, the rotary shaft 9 rotates counterclockwise in FIG. 9, and the cylinder 3b is housed in its original position.

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, +c1 is a central processing unit, which detects at? ep solenoid valve 7
It has a function of controlling the operation of the latching solenoid SL of the water discharging solenoid valve 7b, the latching solenoid LS2 of the water discharging solenoid valve 7b, and the display ED.

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, [C1 outputs a low level output to the name terminal. Thereafter, 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 be turned on, and thereafter the waste water solenoid valve 7a is held in an open state by the self-holding function. Also, T
) The I Tr terminal continues to output a low level output at regular intervals while a person is sitting. When the censor terminal becomes low level, transistors Tr 2 , Tr 8 , Tr 9
is turned on. Other transistors 7r l, Tr 7
, TrlO remain off. As a result, current flows through the latching solenoid LSI of the waste water solenoid valve 7a from the upper side to the lower side in the drawing, and urges the latching solenoid LSI in the opening direction. Then, the waste water solenoid valve 7
a is opened, and the discharging of hot water to the discarded hot water discharge pipe 2e is started. When the TH Tr terminal becomes low level, the transistor T
r5 is turned on, and the temperatures of the waste hot water and the discharge water detected by the waste water thermistor TH1 and the water discharge thermistor TH2 are input to the Tit1 terminal and the TH2 terminal, respectively.

When the waste water temperature detected by the waste water thermistor THI reaches a predetermined temperature, the output of the inspection terminal becomes low level. The output of the censor terminal becomes high level after a certain period of time, that is, enough time for the waste water solenoid valve 7a to turn off, and then the self-holding function #! The main solenoid valve 7a is kept closed. Therefore, when the output of the censor terminal becomes low level,
The transistors Tr1, Tr7, and TrIO are turned on, and a current flows through the latching solenoid Sl of the drain electromagnetic valve 7a from the bottom to the top in the drawing, urging the latching solenoid LSI in the closing direction. Then,
The wastewater solenoid valve 7a is closed, and the wastewater to the famous hot water discharge pipe 2e is stopped.

During this time, the display LED blinks, and as shown in Figure 3, the "Preparing" display on the operating section of the cleaning device blinks, indicating to the user that the water temperature has not reached the temperature. As the temperature of TRI rises to a predetermined temperature, fh
It will stop when the hot water stops.

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, the nozzle device 3 is switched to "private cleaning" or "bidet" as described above.
At the same time, the microswitch 16 is operated in conjunction with the cam portion 15 provided on the shaft 10a of the switching knob 10, and the output of the furrow terminal of the central processing unit ICI shown in FIG. 1 is set to a low level. do. The output of the furrow terminal is
After a certain period of time, that is, a sufficient time for the water spouting solenoid valve 7b to turn on, it becomes high level, and the water spouting solenoid valve 7b is held in an open state by a self-holding function. Therefore, when the output of the furrow terminal becomes low level, the transistor Tr 4
, Tr12 and Tr13 are turned on. The other transistors Tr3, Trll, and Tr14 remain off. As a result, the rafting tureenoid LS of the water discharge solenoid valve 7b
2, a current flows from the upper side to the lower side in the drawing, and urges the rafting tureenoid LS2 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 furrow terminal of the central processing group @ICl becomes low level.

The output of the furrow terminal is for a certain period of time, that is, the water discharge solenoid valve 7b
becomes high level after enough time has passed for it to turn off,
After that, the water discharging solenoid valve 7h is kept in a closed state by a self-holding function. Therefore, when the output of the furrow terminal becomes low level,
The transistors Tr3, Trll, and Tr14 are turned on, and the latching solenoid LS2 of the water discharge solenoid valve 7b is turned on.
, a current flows from the bottom to the top in the drawing, biasing the latching solenoid LS2 in the closing direction. Then, the water spouting electromagnetic valve 7b is closed, and the injection of cleaning water from the expandable nozzle 3C is stopped.

However, if for some reason the water discharging electromagnetic valve 7b does not close even if the rafting tunnel LS2 is biased in the closing direction, the injection of cleaning water from the telescopic nozzle 3c will not stop. Therefore, in the present invention, when the seat switch Sll is turned off, the central processing unit ICI performs the operation shown in the flowchart of FIG.

That is, in FIG. 2, when the seat switch SW is turned off, the central processing unit IC1 detects whether or not water is being spouted, and if water is spouting, the latching solenoid L for water spouting is activated.
A close signal is output to S2 for T1 seconds, for example, 0.02 seconds. Even if water is not being spouted, if hot water is being discarded, a close signal is similarly output to the latching solenoid LSI for Hinoki hot water for T9 seconds. Furthermore, as a precaution, a close signal is output to the water discharging rafting trenoid LS2 and the waste water rafting turingenoid LSI after T2 seconds, for example, 4 to 5 seconds. In this way, the closing action of the self-holding solenoid valve is ensured.

Note that the operation shown in FIG. 2 is based on the temperature detection thermistor Tl11,
To prevent continuous water spouting by performing this also when a protective function is activated, such as when TH2 has an oven failure or short-circuit failure, or when voltage detector IC3 detects a drop in power supply voltage. Can be done.

As mentioned above, the temperature control of the washing water is physically performed by the thermostatic mixing valve, but in the unlikely event that
In order to prevent the washing water from rising to a temperature that is hot to the human body due to incorrect control, a water discharging thermistor T) 12 is used. That is, when the water discharging thermistor T) 12 senses a temperature equal to or higher than a predetermined temperature, the output of the furrow terminal is set to a low level, and a locking operation is performed so that the output of the furrow terminal does not become a low level. Adding such safety devices prevents accidents such as burns that must be avoided at all costs.

Further, in FIG. 1, IC2 indicates an element that makes the power supply voltage of the dry battery constant.

〔Effect of the invention〕

As explained above, in the sanitary cleaning device of the present invention, when a self-holding type solenoid valve is used as the solenoid valve to control water discharge from the cleaning nozzle, the closing operation of the solenoid valve is not performed for some reason. Even in this case, a command signal for closing the solenoid valve is given again when the seating switch is turned off. Thereby, the water spouting operation can be reliably stopped, and the reliability of the operation can be improved when a self-holding electromagnetic valve is used to realize a power-saving sanitary washing device.
