Description

[Detailed description of the invention] (b) Industrial application fields TECHNICAL FIELD The present invention relates to an automatic sheet paper feeding toilet seat.

(b) Prior Art Conventionally, the following methods and devices for setting sheet paper on a toilet seat have been known in consideration of hygiene.

■Take out the sheet paper stored in a paper holder on the wall, folded into four pieces, one by one, spread it out,
This method is to set it on the toilet seat.

■This is a device as described in Japanese Utility Model Publication No. 55-179600, in which a storage surface for storing a sheet paper roll body is provided on the toilet lid, and the sheet paper is pulled out from the storage box onto the toilet seat. This feature is characterized by a structure in which the sheet paper can be pressed and held in conjunction with seating, and the sheet paper can be separated one by one.

■This is a device as described in Japanese Utility Model Publication No. 60-155399, and the device is a sheet of paper that is shaped into a size and shape that can cover the top surface of the toilet seat, and that is a continuous sheet of paper on the sheet. A sheet-like paper holder that stores paper by winding or folding it and continuously feeding out the paper, and a sheet-like paper holder on the paper feeding side of the holder that stores a predetermined length of the paper on the toilet seat. It is characterized by a structure consisting of a feed roller for feeding the paper forward (near the top surface) and a paper feeding cutting section equipped with a cutting blade for cutting the rear end of the fed paper of a predetermined length. It is something.

■This is a device as described in Japanese Patent Publication No. 57-29174, in which a tube feeding device is placed near one end of the seat and a tube take-up device is placed near the other end. The tube is stored in the feeding device, and is characterized by having a drive device for the picking up device and a switch connected to this, and the tube is moved by operating the switch.

(c) Problems to be Solved by the Invention However, the conventional methods and devices described above still have the following problems.

b) First, in the first method, there is no means for holding the sheet paper on the toilet seat, so even if you try to cover the toilet seat with the sheet paper, the sheet paper will slip and fall immediately. Coating work is extremely difficult.

Further, since the sheet paper is not held on the toilet seat, it cannot be accurately positioned on the toilet seat due to the influence of weak moving wind pressure caused by air, making it difficult to handle.

In addition, since the toilet paper is stored in a folded state, when it is unfolded and used, the sheet paper bends at the folds and easily falls off, making it difficult to place it stably on the toilet seat.

Furthermore, after using the toilet, the sheet paper clings to the buttocks, making it uncomfortable.

Regarding the second device (2), the sheet paper had to be fed and fed to the toilet seat manually, which caused inconvenience to the user.

Furthermore, depending on how the user sits, it may not be possible to reliably cut the sheet paper.

In addition, the sheet paper is fed out manually, and some users may not stop it at a predetermined position, and the cutting perforation may not be located at the appropriate position and may move. Sheet paper cannot be cut.

Furthermore, a portion of the sheet paper is always exposed from the outlet for the length required to be pulled out, and water and sewage are likely to adhere to it, and it is also something that can be touched by hand, making it unsanitary.

c) Regarding the third device (■), the sheet paper feeding operation is performed simply by turning on and off the feeding switch, and is not performed via a control device.
- The length of sheet paper that is fed out differs each time, and it is not always possible to accurately feed out a predetermined length. In addition, since the sheet paper roll, feed roller, etc. are configured separately from the toilet seat, they take up installation space and make the space of the toilet etc. narrow.

2) Furthermore, regarding the fourth device (2), the tube is made of plastic film to prevent damage when the tube is fed out, and it feels uncomfortable when seated. In addition, since the tube is moved and rolled up between the tube feeding device and the tube extraction device, it is impossible to determine whether the tube on the toilet seat is a tube before use or a tube after use. The person must move the tube before sitting, and if the tube is not used yet, it will be wasted.

Furthermore, the toilet seat is supported in a so-called cantilever shape, and one side of the seat is dangling, which weakens its strength.

Also, if you place too much weight on the toilet seat, the plastic film will be under pressure between the toilet bowl and the toilet seat, which may cause it to become inoperable.

Furthermore, it cannot be used with front-split type toilet seats.

Furthermore, the used tube is rolled up and stored in the casing, which is unsanitary.

An object of the present invention is to provide an automatic sheet paper supply toilet seat that can solve the above problems.

(d) Means for Solving the Problems The present invention provides a sheet paper roll and a sheet for feeding the sheet paper from the sheet paper roll onto the top surface of the toilet seat body, in a functional casing provided at the rear of the toilet seat body. A paper feeding mechanism section, a control section that controls the sheet paper feeding mechanism section to feed the sheet paper to a set length onto the toilet seat body, and an operation section that operates the control section.
This invention relates to an automatic sheet paper supplying toilet seat characterized by being integrally arranged.

(E) Actions and Effects With the configuration described above, the present invention has the following effects.

(2) Since the sheet paper dispensing mechanism is operated by the control section, the sheet paper can be automatically and accurately dispensed by a certain length onto the toilet seat body, and the sheet paper can be positioned.

In particular, when using the paper in a public place, the user can take out a new sheet of paper from the functional part casing for each use, which improves the feeling of use from a hygienic standpoint.

In addition, since the sheet paper is held on the toilet seat, the usability can be improved.

■Functional part installed at the rear of the toilet seat body Inside the casing, there is a sheet paper roll, a sheet paper feeding mechanism for feeding sheet paper from the sheet paper roll onto the top surface of the toilet seat body, and a sheet paper feeding mechanism that controls the sheet paper roll. The control unit that feeds out the sheet paper to a set length onto the toilet seat body and the operation unit that operates the control unit are housed in an integrated manner, making the multi-functional toilet seat structure more compact overall. This makes it possible to maximize the usable space of the toilet and improve usability.

In addition, due to its compact form, it can be installed on any toilet bowl, and it can also be installed on existing toilet bowls.
At that time, it is easy to replace the existing toilet seat.

(f) Examples The present invention will now be explained in detail based on examples shown in the accompanying drawings.

FIG. 1 shows the overall configuration of a toilet device B equipped with an automatic sheet paper supplying toilet seat A according to the present invention. It is placed on top so that it can be opened and closed vertically.

The structure of the automatic sheet paper supply toilet seat A will be explained in detail with reference to FIGS. 2 to 5.

As shown in the figure, the automatic sheet paper supply toilet seat A includes a toilet seat main body 11 that is placed on a flush toilet 10 so as to be openable and closable;
It is placed in a fixed state on the rear part of the flush toilet bowl 10, and is formed of a functional part 13 at the front part which pivotally connects the rear part of the toilet seat body 11 with a pivot shaft 12 so as to be rotatable in the vertical direction.

As shown in FIGS. 2 to 5, the functional part 13 is attached to the rear part of the flush toilet 10, and has a rectangular plate bent at a right angle with one end side facing the front of the toilet seat body 11 in plan view.
It is formed from a letter-shaped mounting board 20, a sheet paper feeding mechanism section C, a sheet paper cutting mechanism section, a sheet paper roll storage section E, a control section F, and an operation section G mounted on the mounting board 20. .

First, the configuration of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section will be explained. As is clear from FIGS. 2 and 3, the mounting board 20 has rotating shaft support plates 21 and 22 on both ends thereof. A plurality of rotating shafts are rotatably supported horizontally between the support plates 21 and 22.

That is, 23 is a sheet paper feeding shaft that is horizontally suspended between the upper front ends of the support plates 21 and 21, and a large number of feeding rollers 24 are attached to the feeding shaft 23 at predetermined intervals in the axial direction.

Then, the same grade roller 24 cooperates with a pressing roller 71 (described later), presses and clamps the drawing end of the sheet paper P, and feeds out the sheet paper P from the sheet paper roll storage section E onto the toilet seat main body ll. can be supplied.

In addition, since the large number of feeding rollers 24 are arranged in the axial direction at predetermined intervals, the sheet paper P can be fed out at the same speed and with a uniform pressing force over the entire width, and the sheet paper P is prevented from twisting. This effectively prevents this from occurring.

In addition, all of the many feeding rollers 24 have O rings 24.
A is attached to prevent the occurrence of idle rotation or slippage when the sheet paper Phi is ejected. Note that such idling and slipping can be prevented by making the feeding roller 24 itself made of rubber, or by using a rubber belt or the like.

In addition, in FIGS. 4 and 5, reference numeral 25 indicates a support plate 22.
A cutting blade moving shaft formed from a screw punch is horizontally suspended between the lower front ends of the cutting blade 22, and a cutting blade moving guide shaft 26 formed from a solid rod is provided directly above the moving shaft 25.

A cutting blade mounting plate 27 is attached to the cutting blade moving shaft 25 and the cutting blade moving guide ring 26.
is screwed onto the cutting blade moving shaft 25.

Further, a disk-shaped cutting blade 2 is provided at the upper end of the cutting blade mounting plate 27.
8 is rotatably supported.

With this configuration, when the cutting blade moving shaft 25 is rotated,
The cutting blade 28 reciprocates in the axial direction together with the cutting blade mounting plate 27, and can instantly cut the sheet paper P.

In addition, instead of the above-described structure, the mechanism for moving the cutting blade 28 is configured such that an endless wire or an endless belt is driven by a rotary motor so that it can reciprocate in the left and right width direction, and the cutting blade 28 is moved on the endless wire or the like. It can also be configured by binding.

Further, a method of cutting the sheet paper P by reciprocating the cutting blade 28 is proposed using a cutting blade 90 and a cutting blade holder as shown in FIGS. 7 and 8, respectively. a91;
It is also possible to cut the sheet paper P by rotating 3.94. At this time, the above-mentioned cutting by rotation at 180° can be changed to an arbitrary angle.

Note that FIG. 7 shows the rotating shafts 93, 94 in a state where the sheet paper P is being fed, and FIG. 8 shows the rotating shafts 93, 94 in a state where the sheet paper P is being cut. Further, 95 and 96 indicate a holding roller and a feeding roller, respectively.

Further, in the embodiment, the cutting blade 28 is shaped like a disc in consideration of durability, but it can also be shaped like a flat plate.

In addition, in FIGS. 2 and 4, 30 indicates the above-mentioned series 1. −
This is a rotary motor that can selectively rotate the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 via the clutch mechanism M. The switching is performed by switching the rotary motor 30 between forward rotation and reverse rotation. Note that in this embodiment, the rotation motor 30 is fixed to the - side support plate 21.

Then, the sheet paper feeding shaft 2 is connected to the rotary motor 30.
3, the rotation of the gear 31 fixed to the output shaft of the rotary motor 30 is transmitted to the gear train 32°33.34.
, 35, 36 to the gear 37 fixed to the sheet paper feed shaft 23.

On the other hand, the rotational force is transmitted from the rotary motor 30 to the cutting blade moving shaft 25 by fixing a gear 38 to the cutting blade moving shaft 25 and using a gear 32 that meshes with the gear 33 by a clutch mechanism M.
This can be achieved by releasing the mesh by reversing the rotation motor 30 and by meshing the gear 38 with the gear 39 that meshes with the gear 32a that is integral with the gear 32.

That is, the rotational force of the rotary motor 30 is
2a, 39.38 to the cutting blade moving shaft 25.

With this configuration, the single rotary motor 30 is driven by the operation of the clutch mechanism M, and the feeding operation of the sheet paper P and the cutting operation of the sheet paper P are performed by driving the rotary motor 30 in forward and reverse directions. It can be done selectively sequentially.

However, the feeding operation and the cutting operation can also each be performed using dedicated motors.

Note that the rotational force of the rotary motor 30 can be transmitted to the sheet paper feeding shaft 23 and the cutting blade moving shaft 25 using a belt or a wire instead of using a gear train.

Next, the configuration of the control section F that controls the operations of the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section will be explained.

As shown in FIGS. 2 and 4, a control unit mounting plate 50 is erected on a front extending portion 20a extending forward from one end of the mounting board 20. On the board 50,
A control panel 51 is attached to control the operation of the rotation motor 30 described above, and forms a control section F. Note that a transformer 51a is also integrally attached to the control panel 51.

Further, the sheet paper feeding mechanism section C, the sheet paper cutting mechanism section, and the control section F arranged on the mounting board 20 described above are integrated into an L-shaped cover casing 60 having the same external shape as the mounting board 20. is surrounded by.

Next, the operation section G will be explained. As is most obvious from FIG. 4, the operation section G is provided in the cover casing 60 at a location above the control section F.
The operating section G has a sheet paper feeding push button 61. Power lamp 62 consisting of a light emitting diode etc.
It is constructed by installing a paper replenishment lamp 631, a paper jam lamp 64, etc., which have a warning function in the event of an abnormality such as a paper jam or paper replenishment.

Note that a buzzer or the like may be installed instead of the paper replenishment lamp 63 or the like.

Further, above the sheet paper feeding mechanism section C, a sheet paper roll storage section E is provided, as shown in FIGS. 3, 4, and 5.

The sheet paper roll storage section E includes a sheet paper roll storage box 70 that is removably attached within a space formed between left and right side walls 65 and 66 that are integrally provided on the left and right upper surfaces of the cover casing 60, and It is formed of a digit sheet paper roll R that is replaceably installed in the storage box 70 and a pressing roller 71 that is horizontally suspended in front of the lower part of the sheet paper roll storage box 70.

In the above configuration, the sheet paper roll storage box 70 has openings on both left and right end walls 70a and 70b that communicate with openings at both ends of the center axis of the sheet paper roll R, and inside the openings, there are openings in the left and right end walls 70a and 70b. 70
b is provided with a connecting plug 72 that rotatably and detachably connects the sheet paper roll R, and by moving the connecting plug 72 forward and backward in the axial direction, the sheet paper roll R can be easily connected and removed. Can be done.

Note that the connecting plug 72 is prevented from coming off by left and right end walls 65 and 66 on the cover casing 60.

Further, the presser roller 71 presses downwardly into contact with the feed roller 24 attached to the sheet paper feed shaft 23 of the sheet paper feed mechanism section C described above, and the gear 74 fixed to one end of the presser roller It meshes with a gear 73 fixed to the corresponding end of the feed shaft 23.

With this configuration, when the sheet paper feeding shaft 23 and the feeding roller 24 rotate in one direction, the presser roller 7
1 can be rotated in the opposite direction via gears 73 and 74 to unwind the sheet paper P from the sheet paper roll R.

Further, an O-ring 71b is similarly attached to the holding roller 71 in accordance with a predetermined position of the feeding roller 24, and effectively prevents idle rotation, slipping, and twisting when feeding the sheet paper P. .

Furthermore, as shown in FIG. 5, both ends of the pressing roller 71 are connected to swing levers 7 whose base ends are pivoted to the lower part of the front wall of the sheet paper roll storage box 70 so as to be able to swing freely in the vertical direction.
It is rotatably supported at the tip of 1a.

Further, the pressing roller 71 is in pressure contact with the feeding roller 24 and is made of a material with a heavy specific gravity in order to reliably feed the sheet paper P from the sheet paper roll R.

With this configuration, the pressing roller 71 comes into pressure contact with the feeding roller 24 due to its own weight.

Moreover, since the press roller 71 can swing outward, it becomes easy to attach and detach the sheet paper roll R to and from the sheet paper roll storage box 70.

Further, as shown in FIG. 5, a slit 75 for taking out sheet paper is formed between the upper wall 60c of the cover casing 60 and the lower end of the front wall 70c of the sheet paper roll storage box 70.

, Therefore, the sheet paper P unwound from the sheet paper roll R in the sheet paper roll storage box 70
As shown in FIG.
The sheet paper roll R is folded outward by 1.
After uncurling, the paper passes between the pressing roller 71 and the delivery roller 24, and is then delivered onto the toilet seat body 11 through the sheet paper removal slit 75.

Note that the sheet paper roll storage box 70 and the above-mentioned cover casing 60 are integrated to form a functional unit casing H.

Next, the sheet paper P will be explained. As shown in FIGS. 4 and 6, the sheet paper P forms a part of the sheet paper roll R, and is used after being cut.

The reason why the sheet paper P is formed from the sheet paper roll R is that the sheet paper P for a large number of people can be stored compactly in the functional part casing H provided at the rear of the toilet seat main body 11, and This is to enable automatic and accurate feeding onto the upper surface of the main body 11.

In addition, as shown in FIGS. 2 and 6, the sheet paper P has perforations for cutting out at regular intervals in the center of the paper P in a shape that matches the inner shape of the toilet seat main body 11 at predetermined intervals in the longitudinal direction. 80, and an opening communicating with the inside of the flush toilet 10 can be provided along the perforation 80.

However, the perforation 80 is not completely annular, and a non-perforation part 81 is formed between both ends of the rear part.
When the perforation 80 is cut out, the cut out central portion will hang down into the flush toilet bowl 10, and its lower end will be submerged in standing water.

In addition, the sheet paper P is not completely perforated,
The reason why the non-perforated part 81 and the cutout perforation 80 are provided is that if the sheet paper P is perforated, it will not have any stiffness, and when the sheet paper P is fed onto the toilet seat main body 11, it will not bend or the sheet paper roll R may be bent. This is because it is almost impossible to form. On the other hand, the sheet paper P provided with perforations 80 has sufficient stiffness and can easily be both automatically fed and rolled.

Further, the perforation 80 of the sheet paper P allows the sheet paper P to be used by the feeding roller 24 or the presser roller 7 during feeding.
1 can be prevented as much as possible.

Mata, the perforation 80 for cutting out sheet paper P is
It is possible to provide perforations throughout the toilet seat body 11 in a shape that matches the inner shape of the toilet seat body 11, or it is also possible to provide perforations here and there and make cuts elsewhere.

Furthermore, as shown in FIG. 2 and FIG. 6, the sheet paper P has non-perforated portions 81 at regular intervals in the longitudinal direction.
A position detection through hole 82 is provided between the perforation 80 and the tip of the perforation 80, and a position detection sensor 83 is provided at the center of the cover casing 60 corresponding to the through hole 82.

The position detection sensor 83 detects the through hole 82 when the sheet paper P is fed out a predetermined length from the sheet paper roll R, stops the operation of the sheet paper feeding mechanism section C, and accurately Sheet paper P can be supplied and positioned on the toilet seat body 11.

In addition, instead of such a through hole 82, a desired colored mark may be applied to the sheet paper P, and furthermore, the attachment position of the through hole 82 etc. may be not only in the center of the sheet paper P but also at any arbitrary location. be able to.

Further, the above-mentioned supply and positioning of the sheet paper P can be performed using the rotary motor 3 without using the above-mentioned position detection sensor 83.
It is also possible to count the number of rotations at 0 using a desired counter and operate the control unit F based on the counted value.

Further, in FIG. 2, reference numeral 84 denotes a seating sensor consisting of a reflective infrared sensor provided at the front of one end of the mounting board 20.
When the sheet paper P is separated from the sheet paper P, a detection signal is generated, the control section F is activated, and the cutting blade 28 is reciprocated in the axial direction, thereby cutting the sheet paper P instantaneously.

The seating sensor 84 can be integrated into the automatic sheet paper supplying toilet seat A or can be separated and made into a separate body, depending on the usage conditions and usage environment.

Furthermore, in addition to the seating sensor 84, it is also possible to detect the load at the time of seating with a load cell or the like and operate the control unit F to cut the sheet paper P.

In addition, in FIG. 2, 85 cuts off the power to the rotation motor 30 when the toilet seat body 11 is not detected when the toilet seat body 11 is in a state where it cannot be seated (when the toilet seat body 11 is independent). This is a sensor for stopping the supply of sheet paper P, and detects the toilet seat body 11 only when the toilet seat body 11 is in a seatable state and makes it operable.

Note that instead of the sensor 85, a microswitch, a limit switch, or the like may be used.

Below, sheet paper automatic supply toilet seat A having the above configuration
The operation will be explained with reference to the flowchart shown in FIG.

First, turn on the power with the power switch S and check whether the power lamp 62 is lit (100).

Since the power switch S is not particularly required during use,
It is provided on the back surface of the front part of one end of the mounting board 20 (see FIG. 4).

After checking, press button 61 for sheet paper feeding.
Press (101).

At this point, if there is no paper jam or there is no sheet paper roll R, the paper jam lamp 64 or the paper replenishment lamp 63 of the operating section G lights up (102) (103).

11Eao When there is no jam and there is enough sheet paper roll R, or when the paper jam is cleared and the tally sheet paper roll R is set in the sheet paper roll storage box 70, the control section F operates, While driving the rotation motor 30, the clutch mechanism M is also driven to select a gear train that communicates with the feed roller 24 and the press roller 71.

Thereby, the rotation of the rotary motor 30 is transmitted to the delivery roller 24 and the holding roller 71 via the gear train. By the way, since the feed roller 24 and the press roller 71 rotate in opposite directions and hold the sheet paper P in a pressed state, the sheet paper P
is unwound from the sheet paper roll R in the sheet paper roll storage box 70.

That is, as shown in FIG. 5, the sheet paper P is once bent upward and outward by the press roller 71 to uncurl the sheet paper P, passes between the feeding roller 24 and the press roller 71, and then , the sheet paper is delivered and supplied onto the toilet seat main body 11 through the sheet paper take-out slit 75.

In addition, in this feeding operation, when the sheet paper P is fed out a predetermined length onto the toilet seat body ll, the position detection sensor 83 detects the position detection through hole 82 provided in the center of the sheet paper P. , actuates the control unit F to stop the rotation of the rotary motor 30. As a result, the feeding and feeding operation of the sheet paper P by the feeding roller 24 and the pressing roller 71 is also stopped instantaneously, and the sheet paper P is fed onto the toilet seat body 11 by an accurate predetermined length (104 ).

Note that the sheet paper P is curled upward at the stage when it is unwound from the sheet paper roll R, but in this embodiment, the above-mentioned upward curling of the sheet paper P is reversed by the press roller 71 and reversed. After that, the toilet seat main body 11 can be curled downward, and then the toilet seat main body 11 can be curled downward through the paper ejection slit 75.
It can be sent upwards.

Therefore, it is possible to reliably prevent a paper jam accident in which the sheet paper P curls upward and is fed only into the functional part casing H and is not fed onto the toilet seat body 11. It is possible to prevent the sheet paper P from being curled near the paper take-out slit 75 without being fed to a predetermined position.

After that, the user cuts off the center part of the sheet paper P along the perforations 80 leaving only the non-perforated part 81,
Let the cut-off part hang down and attach the tip to the flush toilet 10.
Attach it to the pooled water inside.

As described above, in this embodiment, the sheet paper P can be fed by a predetermined length onto the toilet seat main body 11 by a one-touch operation. Moreover, in this state, the sheet paper P is not cut from the sheet paper roll R, so there is no need to worry about it falling off from the flush toilet bowl 10 or to align it.

In addition, due to the operation of the control unit F, even if the sheet paper feeding push button 61 is pressed while the same sheet paper supply is completed, the next sheet paper P will not be fed or fed, to prevent tampering and to check whether the paper can be used or not. Judgments, etc. are taken into consideration.

Thereafter, the user sits on the sheet paper P on the toilet seat body ll (105).

When the user sits on the toilet seat body 11 and stands up from the toilet seat body 11 after urinating (106), the seating sensor 84 detects that the user has left the toilet seat body 11, and uses the detection signal to activate the control unit F. The clutch mechanism M is actuated to rotate the rotary motor 30, and the clutch mechanism M is activated to rotate the rotary motor 30.
is connected to the cutting blade moving shaft 25 via a gear train,
The cutting blade 28 is moved back and forth to instantaneously cut the sheet paper P (107).

In the above operation, the seat sensor 84 does not detect the seat for at least 10 consecutive seconds (that is, unless the user is seated for 10 consecutive seconds), even if the user stands up from the toilet seat body 11. The control unit F is made inoperable.

Therefore, consideration is given to preventing the cutting operation of the sheet paper P due to erroneous sensing, such as sensing the sheet paper P in the middle of being fed out or sensing an instantaneous motion of the user other than sitting down.

Note that the setting timing of the seating sensor 84 and the time lag for preventing malfunctions can be set according to the environment by the control section F.

After that, the cleaning device is driven to clean the inside of the flush toilet bowl 10,
Due to the force of the washing water, the cut-off portion of the sheet paper P can be drawn in and flowed out together with the washing water and dirt (10B).

In addition, when used in a public place such as a theater, after the series of operations described above are completed, the sheet paper P is automatically supplied onto the toilet seat main body 11 for the next user. It is also possible to activate section F.

With the configuration and operation described above, this embodiment has the following features:
The following effects will be achieved.

■Since the sheet paper feeding mechanism section C is operated by the control section F, the sheet paper P can be automatically and accurately fed out by a certain length from the sheet paper roll R onto the toilet seat body 11. , and can be positioned.

In particular, when using the paper in a public place, the user can take out a new sheet of paper from the functional part casing for each use, which improves the feeling of use from a hygienic standpoint.

In addition, since the sheet paper is held on the toilet seat, the usability can be improved.

■Functional unit provided at the rear of the toilet seat body 11 Inside the casing H, there is a sheet paper roll R and a sheet paper feeding mechanism C for feeding out the sheet paper P from the sheet paper roll R onto the top surface of the toilet seat body 11. Since the control section F that controls the sheet paper feeding mechanism section C to feed out the sheet paper P to a set length onto the toilet seat 2 main body 11 and the operation section G that operates the control section F are housed in an integrated manner, The multi-functional toilet seat structure can be made compact overall, the usable space of the toilet can be maximized, and the usability can be improved.

In addition, due to its compact form, it can be installed on any toilet bowl, and it can also be installed on existing toilet bowls.
At that time, it is easy to replace the existing toilet seat.

Furthermore, in addition to the embodiments described above, there are also features of the structure of other embodiments, and other desirable embodiments.
An example of the transformation will be explained as follows.

■For ease of use for the user, the operation part G is placed on the right side when facing the automatic sheet paper supply toilet seat A, and the letters face forward when operating (while standing), significantly improving operability. can do.

■In this embodiment, the sheet paper automatic supply toilet seat A is provided with a tM mechanism, and the reset mechanism allows the sheet paper P supplied onto the toilet seat main body 11 to be defective or the toilet seat If the sheet paper P is wet due to water droplets adhering to the main body 11, the sheet paper P can be easily removed.

That is, in this embodiment, the reset mechanism is a reset switch 87 provided on the back surface of the front extending portion 20a of the mounting board 20.
By operating the switch 87, the sheet paper P can be cut at any stage and the sheet paper automatic supply toilet seat A can be returned to its initial state without following the normal usage procedure described above. It can be returned.

■To explain the safety mechanism in this actual road example, in order to ensure safety during maintenance, the cutting blade 28 stops operating when a desired sensor (not shown) detects that it is completely housed within the cover casing 60. It is supposed to be done.

■Also, since the sheet paper P is set to be cut inside the functional part casing H, not only is the safety of the user ensured, but the sheet paper P is not cut outside the functional part casing H. Since it is not exposed, it prevents water from adhering.

■In this example, the feeding operation of sheet paper P is as follows:
Semi-automatic, i.e. sheet paper P, toilet seat body ll
The user should carefully take out the sheet paper P from the sheet paper take-out slit 75 of the functional part casing H without accurately feeding and positioning it onto the toilet seat main body 11. It can also be done by

In this case, the position detection through hole 8 provided in the sheet paper P
2 can be made unnecessary.

Furthermore, a rotation motor 30 is used to position the sheet paper P.
The position detection sensor 83 can be made unnecessary by counting the number of rotations by a desired counter and operating the control section F based on the counted value.

In the case of a semi-automatic system, the sheet paper P is configured to be locked by the control unit F after being pulled out for an appropriate length.

In addition, if the sheet paper P is pulled out to an appropriate length, the control unit F will not lock the sheet paper P, so the control unit F is configured so that the next automatic cutting of the sheet paper P upon detection of the seating sensor does not operate. There is.

(2) The sheet paper P can be provided with transverse perforations that can be easily cut after each use, so that the sheet paper P can be cut automatically by the weight of the user as soon as he/she sits on the toilet seat main body 11.

In this case, the sheet paper cutting mechanism can be omitted and the toilet seat configuration can be diversified.

■Water resistance and electrical safety can be improved by collectively covering electrical components (control section F, operation section G, etc.) on one side of the functional section casing H.

■The storage of the sheet paper roll R is completely separated from the sheet paper feeding mechanism section C and the sheet paper cutting mechanism section, taking into consideration the electrical safety when replacing the sheet paper roll R and the safety of the cutting blade 28. It has a box-shaped structure.

(2) The sheet paper take-out slit 75 located at the upper part of the cover casing 60 is provided with an inclination to return water to prevent water from getting onto the sheet paper P as much as possible.

Further, for the same purpose, the storage position of the sheet paper roll R is arranged above the sheet paper take-out slit 75.

[Phase] A microswitch is provided on the cover casing 60 side to detect the set state of the sheet paper roll storage box 70, and if the sheet paper roll storage box 70 is defective or the storage box 0 is removed, safety during maintenance is ensured. In order to ensure security and prevent malfunction, the control section F is made inoperable even if the sheet paper feeding operation button 61 is pressed.

Note that the detection means is not limited to a microsinch, and a sensor, a limit switch, or the like may also be used.

- From the viewpoint of appearance and workability, the sheet paper roll storage box 70 has a structure in which the front side can be slid, hung with a hook, and the rear side can be fixed with a screw.

■The press roller 71 attached to the sheet paper roll storage box 70 is the sheet paper roll R.
In order to easily replace the press roller 71, the press roller 71 is opened by a desired slide mechanism to improve work efficiency.

Further, when the press roller 71 is set in the sheet paper roll storage box 70, a desired spring is used to prevent the lock from coming off during operation.

0 When replacing the sheet paper roll R, the center axis of the sheet paper roll R is aligned with the center of the connecting plug 72, and in order to facilitate roll installation work, the tip of the connecting plug 72 is shaped into a tapered shape. It is shaped like this.

■In addition to the O-ring method, the connection plug 72 can be attached using an L-shaped hook method, or it can be attached to both left and right walls 70a and 70b on the sheet paper roll storage hook 0 side.

■ In the illustrated embodiment, the sheet paper 1 [supply toilet seat A is integrally attached to a regular toilet seat and is of a fully automatic type, but it can also be applied to heated toilet seats, toilet seats with private parts cleaning devices, aromatic toilet seats, etc. It is.

Furthermore, in consideration of design merits, installation space, etc., the toilet seat A can also have the functional section 13 completely separate from the toilet seat body 11, and can be placed on the back side of the wall, for example.

Furthermore, the toilet seat A can also be operated by a remote device.
