Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a toilet seat that can automatically supply flushable and disposable sheet paper onto the seat of a Western-style toilet bowl. To provide an automatic sheet paper feeding toilet seat which prevents the paper from being erroneously fed out again when the toilet seat is being opened, when the sheet paper is being fed out onto the toilet seat, and when the toilet seat is being stood up.

[Conventional technology]

In recent years, many Western-style toilets have come into use in hotels, restaurants, and general households. This Western-style toilet is often used by sitting on a toilet seat that is attached to the toilet so that it can be raised or lowered, so it is desirable that the toilet seat is always hygienic. For this reason, - In general households, a cloth cover is installed on the toilet seat, which tends to become unsanitary due to droplets of sewage adhering to it, and is replaced regularly to prevent it from becoming unsanitary. Rather than cleaning the toilet seat, it is often used to eliminate the feeling of being cold when sitting on the toilet seat. Therefore, if the toilet seat is covered with a cloth cover, it is easy to overlook the adhesion of sewage, and there is a risk that the unsanitary condition will be exacerbated. On the other hand, Western-style toilets installed in public places used by an unspecified number of people, such as hotels, restaurants, and various types of transportation, have
- Unlike ordinary households, toilet seat covers are generally not used at all, and droplets of sewage are directly attached to the toilet seat, which is the same as when a cloth cover is installed. BACKGROUND ART The use of toilet seats by an unspecified number of people is a major public health problem, and the desire to use Western-style toilets installed in public places in a sanitary manner is increasing day by day.

Until recently, to solve the above problem, as seen in Japanese Utility Model Application Publication No. 60-155399, a sheet paper is dispensed in a fixed amount onto the toilet seat using an electrically driven roller, and the toilet seat is seated through the sheet paper. has been proposed, and its schematic structure will be explained with reference to FIG. 1
2 is a toilet bowl, 2 is a toilet seat attached to the toilet bowl 1 so that it can be raised and lowered freely, 3
is a paper holder that holds sheet paper 4 that covers the top surface of toilet seat 2.
A sheet paper roll 4 for feeding out a is rotatably housed. Reference numeral 5 denotes a feed-cutting section that feeds the sheet paper 4a fed out from the holder 3 onto the toilet seat 2 and cuts it into a predetermined length. Set of delivery rollers 7a, 7

and the delivery roller and the cutting blade are individually driven and connected to an electric motor (not shown). When feeding the sheet paper 4a, the delivery roller 7a is driven by the electric motor.
, 7b to feed out a predetermined length of the sheet paper 4a onto the toilet seat, this is read, for example, photoelectrically and the feeding of the sheet paper 4a is stopped, and then another electric motor drives the cutting blade 8a. Drive sheet paper 4a
was disconnected.

[Problem to be solved by the invention]

However, when a toilet seat with the above structure is installed in a Western-style toilet installed in a public place such as a hotel or restaurant where an unspecified number of people go in and out, the sheet paper feeding operation becomes difficult.
Even if you are familiar with the operation from the instruction manual attached to the toilet seat, etc., when you sit on the toilet seat after dispensing the sheet paper, you may accidentally turn off the paper dispensing switch by holding it too tightly while emptying your errand, or as a prank. There may be cases where the user is pushed.

In this case, unless some kind of manipulation prevention means are taken, the sheet paper will be fed out one after another from the sheet paper roll. However, since a user is already seated on the toilet seat, the sheet paper fed out from the sheet paper roll cannot be fed onto the toilet seat, and may get tangled between the feeding rollers or become tangled on the mounting base. There was a risk that it would accumulate inside the tank and cause a blockage.

In view of the above-mentioned problems, the present invention has been developed to prevent sheet paper from being fed out even if the paper feeding switch is operated while the user is sitting on the toilet seat, when the sheet paper is fed out onto the toilet seat, or even when the toilet seat is stood up. To provide a toilet seat that automatically feeds sheet paper so that it is not possible to do so.

[Means to solve the problem]

The present invention includes a detection means on the toilet seat side for detecting when the toilet seat is standing up and when it is sitting, and a detection means on the box side that stores the sheet paper roll for detecting when the sheet paper is fed out onto the toilet seat. The detection means for detecting is further controlled so that the sheet paper is not fed out from the sheet paper roll while both of the detection means are in the detection operation. The present invention relates to an automatic sheet paper supplying toilet seat characterized in that each of the toilet seats is equipped with a control device to prevent sheet paper from being unexpectedly and unnecessarily fed out.

[For production]

The present invention prevents the seat paper from being seated and the sheet paper being removed even if the paper feed switch is operated incorrectly when the sheet paper is fed out onto the toilet seat, when the toilet seat is seated, or when the toilet seat is stood up to clean the toilet bowl, etc. The automatic paper feeding control device is controlled so as not to be activated by the means for detecting presence or absence, and the sheet paper is prevented from being fed unexpectedly or unnecessarily due to mistake, carelessness, mischief, etc., and thereby the sheet paper roll is The present invention is characterized in that clogging due to entanglement or sagging of sheet paper in a box housing the paper and waste due to sheet paper being unnecessarily fed out are effectively prevented.

It is composed of a photocoupler PC and a photocoupler PC.

Next, the operation will be explained.

Before the sheet paper 17a is fed out, as shown in FIG. 5, the feeding opening 23 of the box body 14 is closed by a movable plate 24 to prevent dirty water from entering the box body 14. When the power switch 36 is turned on in this state, the constant voltage power supply Vcc is supplied to each circuit from the output terminal of the power supply circuit 41, and from the output terminal of the half-wave zero cross circuit 42, a voltage slightly higher than the zero cross point is supplied. A pulse waveform signal (see FIG. 10 42) that rises and falls at certain positions is input to the brake signal circuit 45. When the paper feed switch 37 is not turned on by the energization, one input terminal of the AND circuit A that constitutes the drive signal circuit 43 in the automatic paper feed control device 40 is connected to the feed switch 37.
"L" regardless of the output (°'H" or L") level from the paper detection circuit 44 connected to the other input terminal.
level, and as a result, the output terminal of AND circuit A is also “
°L has become parehel. At this time, the clock terminal CPI and output terminal Q of the FF circuit F, 4...L'''
The output terminal Q2 of the FF circuit Ft is also at "L" level, and the drive signal circuit 43 and the operation control circuit 46
No drive signal is output.

(In this embodiment, when the paper feed switch 31 is turned on, the drive control device 47 is set so that the output terminal of the AND circuit A does not go to the "H" level for a certain period of time.) The FF circuit F1 When the output terminal Q1 of is 'L°', both are at 'H' level and the capacitor
1 is charged and the clear terminal CL of the FF circuit F is maintained at H" level, even if the output from the paper detection circuit 44 is input to the clock terminal CP of this FF circuit F. , output terminal Q, are at "L" level. Also, clock terminal CP, , output terminal Q, , F of FF circuit F4
The data terminals of the F circuit F are all at the "L" level, and the clock terminal CP of the FF circuit F,
Even if a pulse signal is constantly input from the half-wave zero-cross circuit 42, the output terminal Q remains at the "L" level because the data terminal is at the "°L" level, and the output terminal Q remains at the "L" level. No braking signal is output. Therefore, the transistor T2 of the operation control circuit 46 is turned off, and therefore the motor 210 energizing circuit is also turned off, and the motor 21 is not driven.

Next, when the paper feeding switch 37 is turned on to feed out the sheet paper 17a, the seating detection circuit 39a remains closed (the seating detection sensor 39 is turned on) unless the toilet seat 12 is raised or seated. 37
(Refer to No. 1012137) The output of the drive control device 47
is input to start the electric motor 29 for the first time, and at the same time,
The control device 47 controls the input terminal to the AND circuit connected thereto so that it does not go to the "H" level.

When the electric motor 29 is started, the cam member 26 rotates, and the movable plate 24 is moved from the 1st position shown in FIG. 5 to the position shown in FIG. When rotated, the electric motor [29] is temporarily stopped by a command from the control device 47, and the input terminal of the AND circuit A is
``Raise the level.

At this time, the sheet paper 17a is as shown in FIG.
Since it is located a little inside the paper feed path 48 from the feed roller 20, the light from the light emitting diode of the paper detection sensor 31 passes through the through hole 24a of the movable plate 24 and is not received by the phototransistor. For this reason,
The output terminal of the paper detection circuit 44 is at the "L" level, but it is inverted by the NOT circuit N, and a "H" level signal is input to the AND circuit A. As a result, the output terminal of the AND circuit A becomes “H” level (see Figure 10, 21).
A pulse rising signal is input to the CP and terminal of FF circuit F, and the H'' level is sent from the drive signal circuit 43 to the operation control circuit 46 via the output terminal Q1 → CP and terminal of FF circuit F2 → output terminal Q2. On the other hand, the output terminal of the FF circuit F becomes "L" level, and the capacitor C1 starts discharging via the resistor R3.

The discharge time is set according to Cz Rs constant fault. When a signal at the "H" level is input to the operation control circuit 46, a signal at the "■]'° level flows from the output terminal of the OR circuit OR to the base of the transistor 'r2 via the resistor R6. to turn it on. Therefore, transistor T2
A light emitting diode D connected to the collector of the photothyristor Th emits light and makes the photothyristor Th conductive. That is, the photocoupler PC is turned on, and the commercial frequency AC power supply is applied to the electric motor 21 to start it (see human power in Figure 10 and 21).
.

electric! When the feed roller 20 is driven by activation of the feed roller 121, the sheet paper 17a unwound from the sheet paper roll 17 and held between the feed roller 20 and the pressure roller 22 is moved to the movable plate 2 as shown in FIG.
While moving on the toilet seat 12, the toilet seat 12 is sequentially fed out from the feeding port 23 while moving on the toilet seat 12. After the sheet paper 17a starts to feed out, when the leading edge of the sheet paper 17a passes under the paper detection sensor 31, the sensor 31 detects this and turns on, and the output of the paper detection circuit 44 reaches the "°H" level. rising,
Clock terminal CP of FF circuits F and l of braking signal circuit 45
3 (see FIG. 10, 44).

However, at this point, the capacitor C3 is not sufficiently discharged (the discharge time of the capacitor C1 is set so that the discharge does not end between the time when the sheet paper 17a is fed out and the time when the sensor 31 detects the tip of the sheet paper 17a). ), the clear terminal CL of the FF circuit F.

is maintained at the “II” level, and the output terminal Q3 becomes “L”.
” level, and the braking signal circuit 45 does not operate (see F4 in FIG. 10). Therefore, the electric motor 21 continues to drive, and the feeding roller 20 feeds out the sheet paper 17a. When the sheet paper 17a is unrolled for a predetermined length onto the toilet seat 12 and the detection hole 33 of the sheet paper 17a is detected by the paper detection sensor 31 (see FIG. 45 FF
It is output to the clock terminal CP of the circuit F (see FIG. 10). At this point, the capacitor C3 is not discharged, and the clear terminal C■4 of the FF circuit F. is at the °°L'' level. As a result, the output terminal Q3 of the FF circuit F3 is at the 'H' level, and the clear terminal CL of the FF circuit F2 is at the 'H' level.
, to the °'H" level, the output terminal Q2 is set to the °"L level.
'' level and stops sending out the drive signal. At this time, the clear terminal CL also reaches the ``11'' level, and at this point, the FF circuits F, , F, forming the drive signal circuit 43 are reset to the initial state. . On the other hand, the output terminal Q of the FF circuit F,
is at the "°H" level, so a pulse rising signal is input to the clock terminal CP of the FF circuit F4, causing its output terminal Q4 to be at the "H" level (see F4 in Figure 10).
. Then, when the data terminal of the FF circuit F is at H" level due to the signal output from the output $Q4 of the FF circuit F4, the rising edge signal of the pulse from the half-wave zero cross circuit 42 becomes the clock of the FF circuit F. When input to the terminal CP5, the output terminal Qs becomes "H" level and outputs a braking signal to the operation control circuit 46 (see 45 in Fig. 10).At this time, the capacitor C1 is charged and discharged with a small constant of C2 and R1. Therefore, the clear terminal CL of the FF circuit F is set to "H" level, and the output terminal Q is set to "L".
“Get back to level.

When the output EQ reaches the L° level, the capacitor C2 becomes a resistor of 1? q and is discharged through clear terminal C
Return L to the "L" degree level. And clock terminal C
When the next pulse signal is input from the half-wave zero cross circuit 42 to P, the operation of setting the output terminal Q to the high level and outputting a braking signal is repeated in sequence. The output time of the braking signal is the time from when the output terminal Q4 reaches the °I (°° level) until the capacitor C4 is charged via the resistor R6 and the clear terminal CL4 is set to the "H" level.

In this way, the detection hole 33 connected to the paper detection sensor 31
When detected, the transmission of the drive signal is stopped, and conversely, a braking signal is input to the operation control circuit 46. Operation control circuit 4
The transistor T2 of No. 6 is intermittently turned on. Therefore, the electric motor 21 is intermittently supplied with AC power.

In this case, since the timing at which the braking signal is output to the operation control circuit 46 is synchronized with the pulse signal output from the half-wave zero-cross circuit 42, the electric motor 21 is (Fig. 10 2)
(Refer to input No. 1)) The motor 21 is braked as if a direct current was being applied to the coil of the motor 21, and the motor 21 suddenly stops. That is, the electric motor [21] stops immediately after detecting the detection hole 33 of the sheet paper 17a (immediately after the detection hole 33 passes the detection point of the paper detection sensor 31). As mentioned above, when the positive half wave of the sine wave is applied to the motor 21 while it is being driven, the coil is energized with direct current, and an alternating current voltage is generated on the rotor side of the motor 21, causing an alternating current ( Eddy current) will flow, but this generated power will be consumed as heat on the rotor side, generating a large braking torque, and as a result, the electric motor 21 will be in a state where DC braking is applied and it will stop. .

As described above, when the output terminal Q of the FF circuit F3 becomes "H" level, the clear terminal CL of the FF circuit F
, becomes the "°H" level, and the output terminal also becomes the "H" level (Q, the "°L" level), charging the capacitor C1 via the resistor R3.

As a result, the clear terminal CL 3 of the FF circuit F3 becomes “
When reaching the "H" level, the output terminal Q changes to the "L" level.As a result, each FF circuit F of the braking signal circuit 45
~F5 are all reset to the initial state. That is, reset the paper automatic feeding control device 40.
.

By feeding out the sheet paper 17a in this manner, it is possible to spread the sheet paper 17a of a predetermined length on the toilet seat 12 as shown in FIG. It can be set accurately between 19 and 19.

When the sheet paper 17a is fed out onto the toilet seat 12, the electric motor 29 is activated again by a command from the drive control device 47, and the cam member 26 is rotated clockwise in FIG. 3 to guide the movable plate 24. It rotates counterclockwise around the pivot shaft d via the roller 25. As the movable plate 24 rotates, the sheet paper 17a located on the side of the cushioning material e is lifted as shown in FIG. to hold. In this state, the movable plate 24 is attached to the cam member 26.
Then, the rotating plate 18 is rotated clockwise in FIG. 6 about the axis a, and the breaking protrusion 19 partially presses the sheet paper 17a. Then, when the cam member 26 rotates close to the highest position, the sheet paper 17a is moved between the feeding roller 20 and the movable plate 2.
At the same time, the rotating plate 1B further rotates toward the movable plate 24 due to the rotation of the movable plate 24, and as a result, the breaking protrusion 19 partially strengthens the sheet paper 17a. Coupled with the fact that a large tension is applied to the sheet paper 17a due to the pressing, the perforations 35 near the breaking protrusion 19 cannot withstand the pressing force of the breaking protrusion 21, and are sequentially torn from that part. Thereby, the sheet paper 17a can be smoothly torn from the perforation 35. After the breakage, the electric motor 29 is temporarily stopped by a command from the drive control device 47. For this reason, the sheet paper 17a
As shown in FIG. 7, the broken end portion of the movable one-turn plate 24, 113 is held in the box body 14 and is extended onto the toilet seat 12.

After this, the user uses the punched piece 32 of the sheet paper 17a.
The person hangs down into the toilet bowl 11 and sits down to relieve himself. In this case, since the sheet paper 17a is held within the box body 14 as described above, it will not move even if the user moves his/her body a little.

Further, when the user is sitting on the toilet seat 12 and relieving himself, the seating detection sensor 39 provided in the seating detection circuit 39a
Since the paper feeding switch 3 is turned off, the paper feed switch 3
Even if 7 is pressed, the paper automatic feeding control device 40 does not operate, and the sheet paper 17a is not fed out unexpectedly.

When the user leaves the toilet seat 12 after relieving himself or herself, the seating detection sensor 39 detects that the user leaves the seat, and the cam member 26 is rotated by a command from the drive control device 47 to start the electric motor 29. , the movable plate 24 is rotated to its original position, that is, in the direction of closing the outlet 23 as shown in FIG.

Further, as the movable plate 24 moves toward the original position, the rotating plate 18 also returns to the position where it contacts the stopper C due to the biasing force of the spring. Note that when the user leaves the toilet seat 12,
Since the sheet paper 17a is held within the box 14, it does not wrap around the buttocks. However, when the movable plate 24 returns to its original position and the grip is released, the force of the flushing water that cleans the inside of the toilet bowl 11 by operating the cleaning device drags the punched piece 32 of the sheet paper 17a into the toilet bowl 11, and the sheet paper along with the sewage. Drain 17a. When the movable plate 24 returns to its original position, the electric motor 29 is stopped by a command from the drive control device 47.

When continuing to feed out the sheet paper 17a,
By performing the same operation as described above, a predetermined length of sheet paper 17a can always be automatically fed out onto the toilet seat 12.

Note that the sheet vapor 17a drawn out onto the toilet seat 12
When the next sheet of paper 17al (k) cannot be used because it is damaged or torn, when the paper feed switch 37 is turned on again, the electric motor 29 is activated by a command from the control device ?ffi 47. 7 and move the movable plate 24 into the shape M (sheet paper 1) shown in FIG.
As shown in FIG. 5, the end of the sheet paper 17a is held between the rotation plate 18 and the sheet paper 17a is rotated in the direction of closing the sheet paper 17a (original position). ). In this state, when the soiled sheet paper 17a is removed from the toilet seat 12 and the paper feed switch 37 is turned on again, the paper detection sensor 31 detects that the sheet paper 17a is not fed onto the toilet seat 12. The automatic paper feeding control device 40 operates to feed the next sheet of paper 17a to the toilet seat 1 in the same manner as described above.
2 Roll out on top.

Also, the sheet paper 17 being fed out onto the toilet seat 12
Even if the paper feed switch 37 is turned on without removing the sheet paper 17a from the toilet seat 12, the paper detection sensor 31 detects the portion of the sheet paper 17a that has been fed onto the toilet seat 12 and remains in the box body 14, Since the input terminal of the drive signal circuit 43 is held at the "Lo" level, the electric motor 21 is not started, and as a result, the sheet paper 17a is suddenly
It is possible to prevent unnecessary waste and mischief.

[Effects of the Invention] As explained above, the present invention includes a seating detection means on the toilet seat side, which includes a microswitch or the like that turns off when a person sits on the toilet seat or when the toilet seat is raised.
Paper detection means that photoelectrically detects the presence of sheet paper on the toilet seat using light-emitting and light-receiving elements is placed near the sheet paper outlet of the box that stores one call of sheet paper. When the toilet seat is placed on the toilet bowl and there is no sheet paper from the paper delivery path inside the box body to the toilet seat, the paper automatic paper delivery control device is activated by the two detection means. Since it is configured to automatically feed out the sheet paper under electrical control, it has the following effects.

(]) When you sit on the toilet seat or when you raise the toilet seat, the sheet paper cannot be fed out even if you operate the paper feeding switch, so it is really possible to prevent double feeding of sheet paper or clogging. can.

(2) Also, when the sheet paper is dispensed onto the toilet seat, a portion of the sheet paper is held by the clamping means and remains inside the box, so a paper detection means should be provided near the dispensing opening of the box. As a result, it is possible to reliably detect that the sheet paper is being fed to the toilet seat-hi, thereby reliably eliminating erroneous operation of the paper feeding switch and mischief, as described above, and preventing the sheet paper from being fed out unexpectedly and wasted. be able to.

(3) Furthermore, if the sheet paper is not discharged into the toilet bowl for some reason after using the toilet and remains from the paper delivery path inside the box to the toilet seat, the paper detection means indicates that the sheet paper has been fed out. Since this is detected and the next sheet of paper is not fed out, it is possible to reliably prevent paper from getting tangled or jammed inside the box.
