DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device for preventing erroneous operation of a toilet bowl with a private parts cleaning device that cleans the private parts after defecating with washing water at an appropriate temperature.

[Technical background of the invention]

In recent years, toilet bowls have been equipped with cleaning devices that spray out cleansing water at an appropriate temperature, allowing for hygienic post-treatment by washing the private parts with cleansing water without having to touch your hands after using the toilet. It's starting to be used.

Generally, in this type of toilet, for example, as shown in FIG. 1, a horizontally elongated control box 3 is attached to the rear of a toilet 2 having a toilet seat 1 on the top surface, and inside this control box 3,
A water supply pipe 4 connected to a water supply source (not shown) is installed in a position suitable for squirting cleansing water toward private parts via a solenoid valve 5, and a nozzle (v6) is connected to the tip of the water supply pipe 4 inside the toilet bowl 2. between this nozzle/I/6 and the solenoid valve 5,
A heating device 7 having a built-in heater for heating the wash water and a temperature sensor inside a cylindrical cane is connected to a brass tube, and as shown in FIG. At the same time, the temperature of the water discharged from the heating device 7 is detected by a temperature sensor, and the detection signal of this temperature sensor is sent to the control device 11 that controls the energization of the heater 8. Control device a1 that received the production IH issue
1 sends a gate signal to control the energization of the switching element 10, controls the energization of the switching element 10, and heats the water flowing into the heating device 7 to an appropriate temperature by the heater 8, and performs this cleaning. It is configured to spray water from a nozzle 6 to clean the private parts. The temperature of the cleaning water is maintained at a constant temperature (approximately 38° C.) by controlling the heater 8 to be energized by the control device 11. Further, on one side of the control box 3, there is an operation box 3 (b) for accommodating the control device 11; it extends along the side of the toilet seat 1, and on the top surface of this operation pock 7-3. is an alternate operation type operation switch (this is a switch that maintains the cutoff state when the push button is pressed) at a position suitable for the user to push and push when sitting on the toilet seat 1.S1, S2
゜S3 has "wash", "dry", "
"Toilet Seat" is displayed.

In addition, in FIG. 4, 12 is a power supply circuit, and this power supply circuit 1
Reference numeral 2 denotes a power transformer 14 connected to the connection terminal 13, a diode bridge 15 having an AC input terminal connected to the secondary side of the transformer 14, and smoothing capacitors C1 and C2 connected in parallel to the DC output terminal of the diode bridge 15. It is configured with a constant voltage device AVR, and supplies the commercial power source as an operating power source to the trailing voltage power source VCOf control device 11, which is voltage-stepped and full-wave rectified.

Next, when using the cleaning device, after using the toilet, press the push button of the operation switch S1 labeled "Washing", the solenoid valve 5 will open, and the tap water will enter the heating device 7 through the water supply pipe 4t. When passing through the water, the cleaning water, which is instantaneously heated by the heater 8 whose energization is controlled by the control device 11 and reaches an appropriate temperature, is ejected from the nozzle 6 toward the private parts to cleanse the private parts. After cleaning, the operation switch SL is pressed again to shut off the circuit, thereby closing the Miiso boat 5 and stopping the jetting of the cleaning water. Thereafter, the user presses the operation switch S2 labeled "Drying" and uses a warm air dryer (not shown) to dry the private parts wetted by the washing. After drying the local area, the operation switch S2 is turned off to stop the hot air dryer. Further, if necessary, the toilet seat 1 may be kept warm by pressing the operation switch S3 labeled ``Toilet Seat J'' to energize a heater for keeping the toilet seat warm (not shown) attached to the back side of the toilet seat 1.

[Problems with background technology]

However, in the above-mentioned conventional toilet bowl with a flushing device, when flushing water is spouted from the nozzle 6, the operation switch S is pressed.
Miisofune 5 was opened by operation 1. A solenoid valve control device 16 for opening and closing the solenoid valve 5 is constructed as shown in FIG. That is, a relay X and an operation switch S1 are inserted in series between the constant voltage power supply Vcc supplied from the power supply circuit 12 and the ground, and a diode D1 is inserted between the terminals of the relay X. When SL is pressed, relay X is energized and its normally open contact
The circuit was closed and the solenoid valve 5 was opened. However, with the Isofune control device 16 having the above configuration, for example, after cleaning the toilet bowl 2 or after doing errands, the dirty water in the toilet bowl cannot be removed by operating the lever of the wash water storage tank (not shown). , if you accidentally press the operation switch S1 labeled "Clean" on the operation box 3 to drain the water in the tank into the toilet bowl 2, or if you press the operation switch S1 while cleaning the toilet bowl 2. If you press the button without realizing it, the solenoid valve 5 may open and wash water may spray out from the nozzle 6, wetting your clothes or the floor of the toilet.

[Purpose of the invention]

The present invention eliminates the above-mentioned drawbacks and prevents cleansing water at an appropriate temperature from being sprayed from the nozzle unless the user is seated on the toilet seat, even if the user operates the operation switch labeled "Wash" on the private parts cleansing device. Another object of the present invention is to provide a device for preventing erroneous operation of a toilet bowl with a private parts cleaning device, which prevents clothes etc. from getting wet due to erroneous operation of the operation switch.

[Summary of the invention]

In the present invention, a seating detection device is installed in one corner of the control box to detect when the user is sitting on the toilet seat. The feature is that when no one is sitting on the toilet seat, even if the operating switch for jetting cleansing water is erroneously pressed, the cleansing water is not spouted out.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5. In FIGS. 2 to 5, the same reference numerals as in FIGS. 1 and 6 indicate the same parts.

In FIGS. 2 and 3, reference numerals 21 and 22 refer to corner portions of the support portion 3 extending to the other side of the control box 3, facing the operation box 3a extending to one side of the control box 3. A light-emitting element and a light-receiving element are attached to the inclined surface 31) (a position facing the user seated on the toilet seat 1). A device that emits light with a certain degree of directivity toward the vicinity is used, and the light receiving element 22 is directed toward the user A.
The distance at which the light from the light emitting element 21 can be detected by entering the light receiving element 22 via the user is determined by a condensing lens (not shown). In this embodiment, user A is seated on the toilet seat 1.
The distance is set to about 50M so that seating can be detected only when a person is seated. Then, the detection means consisting of the light emitting element 21 and the light receiving element 22 detects whether the user
Detects whether K is seated or not.

Next, the configuration of the electromagnetic valve control device 16a including the seating detection device will be explained with reference to FIG. The light emitting element 21 is inserted and connected in series with the resistor R1 between the constant voltage power supply Vcc supplied from the power supply circuit 12 and the ground, and the light receiving element 22 is also connected to the light emitting element 2.
Similarly to 1, a seating detection circuit Y is formed by inserting and connecting the resistor R2 in series between the constant voltage power supply Vcc and the ground. Next, the base of a transistor Q1 is connected to the connection point between the light receiving element 22 and the resistor R2, the collector of this transistor Q1 is connected to the constant voltage power supply Vcc, and the emitter is grounded via the resistor R3. Next, the transistor Q
A transistor base with a grounded emitter is connected to the connection point between the emitter of No. 1 and the resistor R3, and an operating switch S1 and a relay X are connected in series between the collector of this transistor Q2 and the constant voltage power supply VCC. In addition to inserting and connecting,
A diode D1 is connected between the terminals of the relay X to form a switch circuit Z, and the seating detection circuit Y and the switch operation circuit Z constitute a solenoid valve control device 16at.

In the figure, reference numeral 17 denotes a toilet lid that is pivotally supported to the hinge portion 18 of the toilet seat 1 by a hinge rod 19 so that it can be opened and closed freely.
It is pivoted at both ends of the holder so that it can be opened and closed. And toilet seat 1
The light emitting element 21 and the light receiving element 22 are connected to the support part 3 of the control box 3 so that the light from the light emitting element 21 is not blocked by the corner of the toilet seat 1 when the toilet bowl 2 is opened upward.
b It is installed at the corner.

Next, the operation of the electromagnetic valve control device 16a having the above configuration will be explained.

The light emitting element 21 receives constant voltage power supply Vcc from the power supply circuit 12 and always emits light as long as the private part cleaning device is energized. Now, when the user A sits on the toilet seat l, the light emitted from the light emitting element 21 is reflected near the buttocks of the user A and enters the light receiving element 22, as shown by the arrow in FIG. Ru. This I festival, light receiving element 22 and user A
The distance to the buttocks of user A is set to be within about 50 mm when seated on the toilet seat 1, so that the light emitted from the light emitting element 21 is reliably detected by the light receiving element 22. Ru. When light from the light emitting element 21 is incident on the light receiving element 22, the light receiving element 22 is made conductive, and a current from the constant voltage power supply Vcc flows through the light receiving element 22, turning on the transistor Q1. Then, by turning on the transistor Q1, the current supplied from the light receiving element 22 is amplified, and this current is supplied from the connection point between the emitter of the transistor Q1 and the resistor R3 to the base of the transistor Q2, thereby turning on the transistor Q1. let By turning on this transistor, it is detected that the user is sitting on the toilet seat 1. Therefore, when user A presses the operating switch SL labeled "washing" after using the toilet, the operating switch S is turned on in FIG. 5, and the constant voltage power supply
- Operation switch S1 → transistor p Q, flows between the collector → emitter → ground of 2, energizes relay X, and closes its contact Xa. As a result, the solenoid valve 5 is opened, and washing water heated to an appropriate temperature by the temperature control of the control device 11 is ejected from the nozzle/L/6 to wash the user's private parts. When stopping the jetting of cleaning water, the relay X is deenergized by pressing the operating switch S1 again to cut off the operating switch S1. Contact X is opened by opening relay
is opened to cut off the supply of electricity to the solenoid valve 5, and the solenoid valve 5 is closed, thereby stopping the jetting of cleaning water. Then, when the user A stands up from the toilet seat 1, the light from the light emitting element 21 no longer enters the light receiving element 22, so the transistors Q, l, (lp are turned off and seating detection is canceled).

Next, if the user A accidentally turns on the operation switch S1 when the user A is not seated on the toilet seat 1, the light emitted from the light emitting element 21 will be detected by the light receiving element 22, indicating that the user is not seated on the toilet seat 1. Since the range is extremely short, the light from the light emitting element 21 is diffused due to the absence of a reflective object and cannot be received by the light receiving element 22. Therefore, transistor Q1
Since no pace current flows through the transistor and no base current is supplied to the transistor, the transistor does not turn on.

In this state, the relay X is not energized by the operating switch S1 labeled "Cleaning", and therefore the contacts of the relay X remain open, so the solenoid valve 5 is not opened.

Therefore, there is no possibility that the cleaning water will be spouted from the nozzle 6, and it is possible to prevent the cleaning water from being spouted from the nozzle /L/6 by inadvertently turning on the operation switch S1.

In order to distinguish it from outside light and perform seating detection even better, the light-emitting element 21 is biased toward a certain frequency band, and the light-receiving element 22 is a filter that transmits only the above-mentioned frequency band. By using something with these characteristics, seating detection can be further improved.

〔Effect of the invention〕

As explained above, when a user sits on the toilet seat of a toilet with a private parts cleaning device, this seating is detected by a seating detection device consisting of a light emitting element and a light receiving element, and this detection signal is sent to a transistor and an electromagnetic valve. The water is sent to a switch operation circuit consisting of an operation switch that opens and closes, and when cleaning private parts, the solenoid valve is opened by turning on the operation switch, and the cleaning water heated by the heating device is jetted from the nozzle. When cleaning private parts and the user is not sitting on the toilet seat,
Since the light from the light-emitting element does not enter the light-receiving element, the seating detection signal does not flow to the switch operation circuit, and the transistor in the switch operation circuit remains off, so that the solenoid valve does not open even when the operation switch is turned on. As mentioned above, the present invention is configured so that the solenoid valve does not open even when the solenoid valve operation switch is turned on unless the person is seated on the toilet seat. Even when the operation switch labeled "Washing" located on the operation box is turned on, no cleaning water is spouted from the nozzle of the cleaning device, and the jetting of cleaning water drips onto clothes, the floor of the toilet, etc. This eliminates the conventional problem of overheating. In addition, the seating detection device consisting of a light emitting element and a light receiving element is
It can be easily installed using the corner of the control box that houses the heating device and control device, and the switch operation circuit that receives the seating detection signal is a simple circuit that combines a transistor and an operation switch. Since the solenoid valve control device that prevents the malfunction of the private parts cleaning device can be manufactured with a simple structure and at low cost because it can be provided according to the configuration and incorporated into the control device, a special space can be provided in the existing private parts cleaning device. It can be easily installed without any problems. Furthermore, the light emitting/receiving distance between the light emitting element and the light receiving element forming the seating detection circuit is set to the minimum necessary distance so that seating detection can be performed only when the user is sitting on the toilet seat. Since the detection function does not operate unless the person is seated, it has many excellent effects, such as being able to reliably avoid erroneous operations in the private parts cleaning device.
