DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow control device for washing water supplied to a washing nozzle in a sanitary washing device attached to a toilet.

[0002]

2. Description of the Related Art A conventional sanitary washing apparatus of this type is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. Hei 4-122781. As shown in FIG.
A hot water supply system for heating and supplying hot water is connected to the hot water supply system. The hot water supply system includes a valve unit 2 having various electromagnetic valves or needle valves for opening / closing, pressure regulation, and the like connected to an external water supply pipe. The hot water tank 3 is connected to the hot water tank 3. The hot water tank 3 is provided with a heating means 3a, a temperature sensor 3b and the like, and heats the inflowing water to a set temperature and sends it to the cleaning nozzle 1. An intermittent supply device 4 for supplying hot water intermittently to the posterior side or bidet side of the washing nozzle 1 is incorporated in the path from the hot water tank 3 to the washing nozzle 1. The intermittent supply device 4 is driven by a motor 5 so that an interval of intermittent supply of the washing water from the hot water tank 3 can be set appropriately. The motor 5 of the intermittent supply device 4, the motor 1 a of the cleaning nozzle 1, the opening and closing of the valve unit 2, the heating of the hot water tank 3, and the driving of the intermittent supply device 4 are all controlled by the control unit 6, and the operation switch 7 performs the cleaning. The device can be operated. FIG.
3 shows details of the intermittent supply device 4. The casing 8 has an inflow passage 9 connected to the hot water tank 3 and a two-system outflow passage 1 communicating with the bidet side or the bottom side of the washing nozzle 1.
0a and 10b are formed. In the middle of the inflow channel 9 and the outflow channels 10a and 10b, the inflow channel 9 and the outflow channel 10
The rotor 11 for communicating with a and b is incorporated. The output shaft of the motor 5 is directly connected to the shaft of the rotor 11. When the motor 5 is operated by a signal from the control unit 6, the rotor 11 rotates forward and backward at a set speed.

When the washing switch (not shown) of the operation switch 7 is turned on to the posterior or bidet side of the operation switch 7 according to the above configuration, the valve unit 2 opens the flow path and removes the hot water which has been heated in advance to the set temperature. It is extruded from the tank 3 and supplied to the cleaning nozzle 1. At the same time, the motor 5 of the intermittent supply device 4 operates to rotate the rotor 11 in the forward and reverse directions. On the other hand, in the intermittent supply device 4, when the switch is turned on, the flow grooves 11a and 11b of the rotor 11 rotate in the direction of the arbitrarily selected outflow paths 10a and 10b, and are adjusted to an arbitrary flow area. That is, the flow channel 11a and the outflow channel 10
a, the rotor 11 rotates from the state where none of the outflow grooves 11b and the outflow passages 10b are in communication with each other, and the flow channel 1
When 1a overlaps the flow path cross section of the outflow path 10a, the flow path is opened and hot water is sent to the bottom side of the washing nozzle 1. The amount of hot water sent to the cleaning nozzle 1 depends on the flow channel 1
The flow area is controlled by the flow path area formed by the flow path 1a and the outflow path 10a, and the flow path area is increased or decreased by rotating the rotor 11 by the motor 5 because the cross-sectional area of the flow path groove changes along the circumferential direction. Can be.

[0004]

However, in the above-described conventional configuration, if the valve unit is opened by the cleaning start signal in a state where the flow path from the hot water tank to the cleaning nozzle is fully opened by the intermittent supply device, Cleaning water will suddenly blow out from the cleaning nozzle. When the valve unit is opened by the washing start signal in a state where high-pressure water flows from the water supply passage and the flow path from the hot water tank to the washing nozzle is closed by the intermittent supply device, the high-pressure water is closed. Since the hot water tank flows into the hot water tank, sudden pressure fluctuations occur in the hot water tank, and the hot water tank is likely to be broken or leaked. In the above-described conventional configuration in which the intermittent water supply, that is, the intermittent supply device capable of adjusting the flow rate is provided in the flow path from the hot water tank to the washing nozzle, the degree of opening of the intermittent supply device at the start of washing is controlled each time washing is started. Since the flushing of the washing water is started without any trouble, the sudden flushing of the washing water may cause discomfort to the user or cause a leak from the hot water tank.

When the valve unit is closed by a washing stop signal in a state where the flow path from the hot water tank to the washing nozzle is closed by the intermittent supply device, the hot water tank is sealed with high water pressure applied. Will be done. In addition, if the flow path from the hot water tank to the cleaning nozzle is stopped by the intermittent supply device by the cleaning stop signal, if the water leaks from the valve unit or the like occurs, the water flows into the hot water tank, and As a result, the cleaning water in the hot water tank flows out through the intermittent supply device and the cleaning nozzle. As described above, in the above-described conventional configuration, the degree of opening of the intermittent supply device at the end of cleaning is not controlled, so that the supply water pressure is confined in the hot water tank, thereby causing the destruction or leakage of the hot water tank or the occurrence of water in the hot water tank. There has been a problem that the outflow of the washing water increases the energization time of the heating device and increases the running cost.

The present invention solves the above-mentioned conventional problems. In a sanitary washing apparatus having flow control switching means capable of switching a plurality of flow paths and controlling the flow rate of washing water,
In particular, when the user starts cleaning a human body part, he / she does not feel discomfort due to sudden ejection of cleaning water, and furthermore, sudden pressure fluctuations in the hot water tank may cause damage to the hot water tank or leakage. It is a first object to provide a sanitary washing device without any.

A second object of the present invention is to provide a sanitary washing apparatus having flow control switching means capable of switching between a plurality of flow paths connected to a washing nozzle and controlling the flow rate of washing water. Remains trapped in the tank
An object of the present invention is to provide a sanitary washing device capable of closing a washing flow path from a hot water tank to a washing nozzle after reliably removing pressure and preventing outflow of washing water in the hot water tank.

[0010]

According to the sanitary washing device of the present invention,
When an instruction to start washing is given by the setting means, the time difference opening means provided in the control device first outputs a signal so that the flow control switching means becomes the washing start opening degree, and then opens the water stop solenoid valve. I do. That is, the time difference opening means first outputs a drive signal to the drive means provided in the flow control switching means at the start of cleaning. Here, the driving means rotates the flow control switching valve element in response to a signal sent from the time difference opening means, and operates so that the flow path from the hot water tank to the washing nozzle communicates at a predetermined washing start opening. At this time, the time difference opening means provided in the control device acts to open the water stop solenoid valve provided in the water supply passage with a predetermined time delay from the drive signal output of the flow control switching means. Accordingly, at the start of washing, the water shutoff solenoid valve operates so that the flow path from the hot water tank to the washing nozzle always communicates at a predetermined opening for washing, so that the flow from the hot water tank to the washing nozzle is opened. When the water stop solenoid valve is opened when the water stop solenoid valve is opened with the passage fully open, or when the water stop solenoid valve is opened with the flow path from the hot water tank to the wash nozzle closed. A sudden increase in pressure in the hot water tank that occurs can be prevented.

Further, the sanitary washing apparatus of the present invention has the above-described configuration, and when the setting stop means gives an instruction to stop washing, the sanitary washing apparatus is controlled.
The time difference closing means provided in the apparatus first closes the water stop solenoid valve, and then the flow control switching means holds the communication opening degree of the flow path from the hot water tank to the washing nozzle at a predetermined washing end degree.
After that, a signal is output so as to be closed with a delay . That is, at the end of the washing, the time difference closing means first closes the water stop solenoid valve and cuts off the supply of the water supply pressure from the water supply passage. Further, the time difference closing means outputs a driving signal to a driving means provided in the flow control switching means. Here, the driving means drives the flow control switching valve body based on the signal sent from the time difference closing means ,
Predetermined cleaning of the flow path from the hot water tank to the cleaning nozzle is completed
After maintaining the communication at the opening degree, it acts to close the flow path from the hot water tank to the washing nozzle. This allows
At the end of washing, the water stop solenoid valve is closed and the supply source of the water pressure supplied to the hot water tank is cut off.After that, the flow path from the hot water tank to the washing nozzle is maintained at the predetermined washing end opening.
Therefore, the supply pressure remaining in the hot water tank is surely discharged into the toilet through the washing nozzle. Therefore, the water supply pressure is not trapped in the hot water tank. Furthermore, when the supply pressure remaining in the hot water tank is discharged, the flow path from the hot water tank to the washing nozzle is closed, so that the inside of the hot water tank is washed by water leakage from the water stop solenoid valve or a siphon effect. The outflow of water can also be prevented.

Further, the washing water heated to an appropriate temperature in the hot water tank 12 is subjected to selection of a flow path system leading to the first washing nozzle 17a or the second washing nozzle 17b and flow rate adjustment thereof by the flow adjustment switching means 19, It is ejected from the first cleaning nozzle 17a or the second cleaning nozzle 17b to the human body part. The control unit 20 controls the water stop solenoid valve 18 and the flow control switching means 19 to select the flow path system to the first cleaning nozzle 17a or the second cleaning nozzle 17b, adjust the flow rate, and start and stop the cleaning.
This is done by outputting a drive signal to

Or the flow to the second outflow channel 22b is determined, and the flow rate is adjusted and guided to the selected washing flow path system.

FIG. 2 is a perspective view of the flow control switching means. The rotation range of the motor 27 and the flow control switching valve 26 is restricted at a position where the rotary piece 25 contacts the fixed pieces 25a and 25b.

Next, the control device 20 will be described in detail. The control device 20 is provided with a time difference opening means 28a and a time difference closing means 28b. When the cleaning is started, the time difference opening means 28a switches the flow control switching means 19 from the hot water tank 12 to the first position.
After outputting a signal so that the flow path leading to the cleaning nozzle 17a or the second cleaning nozzle 17b is communicated at the cleaning start opening, the control is performed to open the water stop electromagnetic valve 18 with a delay. Here, the cleaning start opening degree in the present embodiment is about 1 when the communication opening degree of the flow path from the hot water tank 12 to the first cleaning nozzle 17a or the second cleaning nozzle 17b is in a fully open state.
The communication opening degree was about / 10. Also, the time difference closing means 2
8b, at the end of washing, after closing the water stopping electromagnetic valve 18, the flow control switching means 19 causes the first washing nozzle 1 to move from the hot water tank 12 to the first washing nozzle 1;
After maintaining the flow path to 7a or the second cleaning nozzle 17b at the cleaning end opening degree, control is performed so as to close the opening. Here, the cleaning end opening degree in the present embodiment was set to a substantially fully opened state so that the water supply pressure trapped in the hot water tank 12 was easily discharged.

Next, the operation of the above embodiment will be described.
First, the washing water flowing into and stored in the hot water tank 12 through the water supply passage 16 is heated by the heating means 13 until its temperature is detected by the temperature sensor 14 and reaches the temperature set by the operation switch 29 as the setting means. . Here, when an instruction to start the posterior washing is given by the operation switch 29, the time difference opening means 28a provided in the control device 20 causes the flow control switching means 19 to switch the flow path from the hot water tank 12 to the first washing nozzle for the posterior washing. Is output at the cleaning start opening, and then the electromagnetic valve 18 for stopping water is opened. That is, the time difference opening means 28 a provided in the control device 20 first outputs a drive signal to the motor 27 provided in the flow control switching means 19 at the start of cleaning.
Here, the motor 27 rotates the flow control switching valve element 26 in response to a signal sent from the time difference opening means 28a, and the cutout flow path 24 provided in the flow control switching valve element 26 communicates with the first cleaning nozzle 17a. The first outflow path 22a is directed to the direction, and the communication opening is operated to be the cleaning start opening.
At this time, the time difference opening means 28 provided in the control device 20
a is delayed from the drive signal output to the flow control switching means 19,
Control is performed so as to open the water stop electromagnetic valve 18 provided in the water supply passage 16. When the water stop solenoid valve 18 is opened, water flows into the hot water tank 12, and the washing water heated and stored at an appropriate temperature in the hot water tank 12 is pushed out, and the above operation of the flow control switching means 19 optimizes the cleaning water. A flow of cleaning water is jetted from the first cleaning nozzle 17a. This operation is performed using the operation switch 29.
When the start of the local cleaning of the woman is instructed, the notch flow path 24 provided in the flow control switching valve body 26 faces the direction of the second outflow path 22b communicating with the second cleaning nozzle 17b,
The same applies except that the communication opening is adjusted. Thus, at the start of cleaning, the water stop electromagnetic valve 18 operates so that the flow path from the hot water tank 12 to the first cleaning nozzle 17a and the second cleaning nozzle 17b always communicates at the cleaning start opening. Therefore, sudden flow of washing water generated when the water shutoff solenoid valve 18 is opened with the flow path from the hot water tank 12 to the first washing nozzle 17a or the second washing nozzle 17b being fully open, or the hot water tank 12 Abrupt pressure fluctuations in the hot water tank 12 that occur when the water shutoff solenoid valve 18 is opened with the flow path from the first to the first washing nozzle 17a or the second washing nozzle 17b being closed can be prevented.

At the start of cleaning, the flow control switching means 19 sets the communication opening degree of the flow path from the hot water tank 12 to the first cleaning nozzle 17a or the second cleaning nozzle 17b to the first cleaning nozzle 17a or the second cleaning nozzle 17b. Control so that the washing water squirted from the nozzle does not reach the human body part, and maintain the communication opening degree for a time sufficient to discharge the cold water or dirty water remaining inside the first washing nozzle 17a or the second washing nozzle 17b. By performing such control,
It is possible to prevent the cold water in the cleaning nozzle or the polluted water in the nozzle from being jetted directly to the human body part because it has not been used for a long time, and it is possible to perform sanitary cleaning without giving the user any discomfort.

When the user cleans the buttocks and gives an instruction to stop the cleaning with the operation switch 29, the control device 2
The time difference closing means 28b provided at 0 first closes the water shutoff solenoid valve 18, then outputs a signal so that the flow control switching means 19 maintains the washing completion opening, and then closes with a delay.
And outputs the order of the signal. In other words, the time difference closing means 28b provided in the control device 20 first closes the water stop electromagnetic valve 18 at the end of the cleaning and cuts off the supply of the water supply pressure from the water supply passage 16. Further, the time difference closing means 28b is connected to the flow control switching means 19.
And outputs a drive signal to the motor 27 provided in the controller. Here, the motor 27 rotates the flow control switching valve body 26 according to a signal sent from the time difference closing means 28b, and the flow control switching valve body 2
6 is provided with the first cleaning nozzle 17
After facing the direction of the first outflow passage 22a communicating with the first cleaning nozzle 17a, and further operating so that the communication opening becomes the cleaning end opening, the flow path from the hot water tank 12 to the first cleaning nozzle 17a is closed. Perform control. In this operation, when the local washing of the woman is completed by the operation switch 29 and the stop of the jetting of the washing water is instructed, the cutout channel 24 provided in the flow control switching valve body 26 is connected to the second washing nozzle 17b. The same applies except that the direction of the communicating second outflow passage 22b is adjusted and the opening degree of the communication is adjusted. Thus, at completion of cleaning after the water stopping solenoid valve 18 is supplied source supply water pressure to be supplied to the hot water tank 12 is closed is cut off, the flow path is predetermined cleaning ends open, from the hot water tank 12 to washing nozzle To maintain the degree,
The supply pressure remaining in the hot water tank 12 is surely discharged into the toilet through the washing nozzle. For this reason, the water supply pressure is not trapped in the hot water tank 12. Further, when the supply pressure remaining in the hot water tank 12 is discharged, the flow path from the hot water tank 12 to the first washing nozzle 17a and the second washing nozzle 17b is closed, so that the electromagnetic valve 18 for stopping water is used.
Hot water tank 1 due to water leakage and siphon effect
The outflow of the washing water in 2 can be prevented.

In addition, the flow control switching means 19 in the present embodiment.
The flow control switching valve element 26 provided with the notch flow path 24 on the shaft surface having a circular cross section facilitates processing and leads to a reduction in production cost.

Further, since the flow regulating switching valve body 26 in this embodiment is provided with the rotation regulating means 25 for regulating the rotation angle thereof, the rotation of the motor 27 is necessarily regulated, so that it cannot be predicted. Erroneous operation can be avoided. Furthermore, if control is performed with one end point of the allowable rotation range regulated by the rotation regulating means 25 as a zero point,
With a simple configuration, accurate flow control and switching of the cleaning nozzle to be used can be performed.

In this embodiment, the drive means provided in the flow control switching means is a general motor, but if this is a stepping motor, the flow rate can be controlled more accurately and the washing nozzle can be switched by utilizing its characteristics. Becomes possible. That is, when an instruction to start washing is given by the operation switch 29, the time difference opening means 28a provided in the control device 20 first sends a pulse signal to the flow control switching means 19, and sends the pulse signal to the flow control switching means 19.
It is possible to perform a predetermined operation after resetting the origin every time by using the phenomenon of step-out of the stepping motor 27 provided in the above. In other words, specifically, since the flow regulating switching valve body 26 is provided with the rotation regulating means 25,
The permissible rotation ranges of the flow control switching valve body 25 and the motor 27 are mechanically determined in advance. On the premise of this, if a pulse that exceeds the allowable rotation range and is still rotated is given to the motor 27, the motor 27 will lose synchronism when the motor 27 rotates to the end point of the allowable rotation range. Utilizing this phenomenon of step-out, the end point of the allowable rotation range of the flow control switching valve element 26 is detected, and the detected end point is recognized as the origin. For this reason, the starting point of the stepping motor 27 is determined each time the jetting of the washing water is started, and accurate control of the flow control can be performed.
