Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a toilet seat equipped with a sheet paper supplying device that automatically spreads a large sheet of paper on the top surface of the toilet seat, thereby making it possible to use the Western-style toilet hygienically.

[Conventional technology]

In recent years, as lifestyles have become more Westernized, many Western-style toilets have come into use in restaurants, hotels, and general households. However, when using a Western-style toilet, one rests one's buttocks directly on the toilet seat, which means one's skin comes into direct contact with the toilet seat, which makes Japanese people, who tend to be very clean, feel a certain sense of discomfort. For this reason, for example, in ordinary households, the above-mentioned problem is solved by covering the toilet seat with a seat cover made of cloth or knitted with wool. However, in toilets used by an unspecified number of people, such as in hotels, restaurants, trains, and passenger planes, even if the cover is covered, unlike in ordinary homes, there is a strong sense of reluctance to touch a toilet seat that has been used by a stranger. There is. For this reason, in Western-style toilets in hotels and the like that are used by many people, users often place toilet paper on the toilet seat for hygiene reasons. However, this is very troublesome for users, and today there is a growing desire for the toilet seat to always be covered with a fresh cover so that it can be used hygienically.

[Problems to be solved by the invention]

For this reason, for example, as shown in Japanese Patent Application Laid-Open No. 60-225529, before sitting on the toilet seat when using a Western-style toilet, it is necessary to use a toilet seat large enough to sufficiently cover the top of the toilet seat and in the central part. An oval punched part of a size corresponding to the opening of the toilet seat has a part connected to the outer edge of the water-soluble sheet paper, which is taken out one by one from the storage box and placed over the entire top surface of the toilet seat. Accordingly, a toilet seat equipped with sheet paper for sanitary use of a Western-style toilet has been proposed. When using the sheet paper, cover the toilet seat with the paper and sit on it, then separate the connecting part of the punched part, let only the punched part hang down in the toilet bowl, and partially submerge it in water, After using the toilet, the flushing water would cause the sheet paper on the toilet seat to be dragged into the toilet bowl and discharged along with the defecated water. In this way, when using a Western-style toilet, it is very hygienic to place toilet paper or special sheet paper on the toilet seat and sit on it. However, as mentioned above, in order to use the toilet seat in a clean state, it is very troublesome to use toilet paper or large sheet paper on the toilet seat each time to use the toilet seat. For example, toilet paper has a very narrow width, so even if you place it on the toilet seat, when you sit down,
Or, if you move your body while sitting,
The paper itself may move with you, causing part of your butt to come into direct contact with the toilet seat. In this case, I had to refill the appropriate amount of toilet paper, so
It was very troublesome. Also, if you use a large sheet paper, approximately 40
It is a large piece of paper measuring ~50 cm, and the paper is soft and thin, like toilet paper, and can be washed and discarded. Therefore, they are very weak and it is difficult to take out such large sheets of tissue paper one by one from the storage box as needed.In particular, the sheet paper has a punched part in the center that corresponds to the opening of the toilet seat. Since the sheet paper and a part thereof are connected to each other, when the sheet paper is pulled out from the storage box, it often breaks from the punched part to the outer edge of the sheet paper, making it useless. Moreover, it is extremely difficult to use, as multiple cards are often drawn out at the same time.
Moreover, it was uneconomical. Larger sheet paper was folded one by one and stored in a storage box like toilet paper, but it was a large thin paper and had a punched part in the center to allow it to hang inside the toilet bowl. It is actually difficult to fold these sheets one by one, and it is also difficult to mechanize them.In the end, the folding must be done by skilled hands, resulting in very low productivity and high costs. It was hot.

[Means for Solving the Problems] In view of the above-mentioned problems, the present invention automatically brings out the sheet paper covering the top surface of the toilet seat one by one by electric operation without manually pulling out the sheet paper. Cover the toilet seat and when using a Western-style toilet,
To provide a toilet seat equipped with a sheet paper supply device that allows a user to relieve himself while sitting on the toilet seat with peace of mind in terms of hygiene.

[Effect]

The present invention feeds a fixed amount of soft, thin sheet paper wound into a roll stored in a sheet paper supply device from the paper outlet of the supply device to the top surface of the toilet seat using an electrically driven paper feed roller. After covering the toilet seat, one side of the sheet paper in the length direction is held in the center by the perforation that marks the separation of the first sheet of sheet paper, and the other side of the sheet paper is held between the paper feed rollers. ,
It is held between a plate-shaped movable plate that is rotated by a predetermined angle by an electrically driven cam member and a swinging plate that is integrally provided with a plurality of breaking protrusions on the paper feed roller side, and in this state, the The movable plate is rotated by a predetermined angle, and while holding the sheet paper, the swing plate is rotated in the opposite direction of the movable plate, and the sheet paper is placed under a large tension between the paper feed roller and the movable plate. At the same time as this tension is applied, the breaking ridge provided on the rocking plate collides with the sheet paper, and the part of the sheet paper where the breaking ridge collides is pressed with a larger force than other parts. , a piece of sheet paper is broken by sequentially tearing the perforations located close to the area where this pressing force was applied, and the broken sheet paper covers the top surface of the toilet seat and a part of the broken sheet paper. is held between the movable plate and the swinging plate in the supply device to prevent the sheet paper from moving from the toilet seat even if you move while seated, and furthermore, after using the toilet, the sheet paper Release the grip and drag the paper into the toilet bowl to discharge it. After discharging the paper, the paper outlet of the sheet paper supply device is closed by a movable plate to prevent urine and other dirty water from entering the supply device. It is characterized in that it is configured to prevent this.

2, light emission for detecting the presence or absence of the sheet paper 40 that is attached without hindering the feeding of the sheet paper 40;
In each light-receiving element, the light from the light-emitting element 48 is, for example,
It is reflected on white paper such as the sheet paper 40 and detected by the light receiving element 49 (indicating the presence of paper), and is provided in the center of the sheet paper 40 corresponding to the opening 3a of the toilet seat 3. When the light-emitting element 48 matches the through-hole 30 provided at the rear of the punched part (see FIG. 6) 44 (when a fixed amount of sheet paper 40 is fed to the toilet seat 3), the light-emitting element 48
When light passes through the through hole 30 and reaches the tongue piece 31 of the cover 45, if the tongue piece 31 is colored other than white, the light is absorbed and cannot be detected by the light receiving element 49. First, as a result, the electric motor 8 of the paper feed roller 6 is stopped by a command signal from the control device S, and the feeding of the sheet paper 40 is stopped. Further, in FIG. 1, 32 is a power switch of the device of the present invention, 33 is a power lamp, and a fourth
Reference numeral 34 shown in the figure is an outside air intake port, through which outside air flows into the paper feed box 4 by cooling fans (not shown) of the motors 8 and 9, it passes through the circulation hole 35 and enters the paper delivery path 4.
2, and the sheet paper 40 is delivered to the delivery path 42.
The sheet paper 40 is fed out in a slightly raised state within the paper to prevent paper jamming of the sheet paper 40 during feeding. In the feeding device 2 of the present invention, the operation control of the electric motors 8 and 9 is all sequentially controlled by a control device S built in the other extending portion 4b of the paper feed box 4. Next, the operation will be explained. When the Western-style toilet bowl 1 is used, the movable plate 10 in the supply device 2 closes one end of the paper outlet 43, as shown in FIG. prevent intrusion. In this state, now Western-style toilet 1
When using this, first, when the power switch 32 is turned on, the lamp 33 lights up, the electric motor 9 is started, and the cam member 15 is rotated clockwise in FIG. As shown, the electric motor 9 is temporarily stopped by a command signal from the control device S when it becomes substantially parallel to the paper feeding path 42. That is, the paper outlet 43 is opened. When the movable plate 10 stops in the state shown in FIG. 3, the electric motor 8 is immediately activated by a command signal from the control device S, and the sheet paper 40 is fed out while being held between the paper feed roller 6 and the pressure roller 7. The paper is delivered through the passage 42 toward the paper delivery port 43. For this reason, a roll of sheet paper 40
is pulled out onto the toilet seat 3 from the paper outlet 43 of the paper feed box 4 while being sequentially rewound. At this time, the light from the light emitting element 48 is reflected by the sheet paper 40 and detected by the light receiving element 49. And the sixth
As shown in the figure, when one sheet of sheet paper 40 is placed on the toilet seat 3, the sheet paper 40
The through hole 31 that opens to the rear of the cutout 44 matches the light emitting element 48 provided inside the paper outlet 43, and the light from the light emitting element 48 passes through the through hole 31 to the tongue piece of the cover 45. 31 and is not reflected, is not detected by the light receiving element 49, and is not reflected by the light receiving element 49.
The detection signal from is not input to the control device S. As a result, a command signal to stop the electric motor 8 is sent from the control device S, the electric motor 8 is stopped, and feeding of the sheet paper 40 is stopped. At this time, a perforation 41 that forms a boundary between one sheet of sheet paper 40 to be laid on the toilet seat 3 is set in advance so that it is located between the breaking ridge 26 of the swing plate 21 and the paper feed roller 6. . After feeding out the sheet paper 40, the electric motor 9 is restarted by a command signal from the control device S, rotates the cam member 15 clockwise in FIG. Movable plate 1 by roller 12
0 is rotated about the pivot pin 11 in the opposite direction to the cam member 15. Therefore, as shown in FIG. 7, a part of the sheet paper 40 staying in the paper feed path 42 is transferred to the paper feed roller 6 side of the rotary plate which is rotated counterclockwise by the cam member 15. is lifted by the end of the swing plate 21 and pulled toward the buffer material b side of the swing plate 21. Then, the movable plate 10 rotates using the space between the cushioning material b of the rocking plate 21 and the breakable protrusion 26, and the cushioning material a comes into contact with the cushioning material b of the rocking plate 21. The lifted sheet paper 4
0 is sandwiched between buffer materials a and b. When the movable plate 10 continues to rotate further by the cam member 15 in this state, the swing plate 21 rotates clockwise in FIG. 7 about the pivots e and e against the force of the helical spring f. However, a large tension is applied to the sheet paper 40 existing between the paper feeding and pressing rollers 6, 7 and the cushioning materials a, b, and the tip of the breakage protrusion 26 becomes as shown in FIG. Contact with sheet paper 40. In this case, the gears G and G of the paper feeding roller 6 and the pressing roller 7 mesh with each other, and the pressing roller 7 does not idle, so that the tension of the sheet paper 40 remains unchanged. From this point on, while the movable plate 10 is rotated to the maximum angular position by the cam member 15, the sheet paper 40 held between the movable plate 10 and the paper feed roller 6 has An even larger tension is applied, and the tip of the breaking protrusion 26 causes the portion of the sheet paper 40 that comes into contact with it to
is pressed with a large force, and the perforation 41 near the part that contacts the breakage protrusion 26 cannot withstand the pressing force, and is torn one by one from that part, as shown in FIG. 9. The sheet paper 40 is broken at a perforation 41 shown by a dashed line in FIG. When the sheet paper 40 is torn, the electric motor 9 driving the cam member 15 is temporarily stopped by a command signal from the control device S. Therefore, the torn sheet paper 40 is
As shown in the figure, the torn edge of the sheet paper 40 is held between the movable plate 10 and the swing plate 21 to prevent the torn sheet paper 40 from shifting or sliding off the toilet seat 3. Thereafter, the user sits on the toilet seat 3 via the sheet paper 40, drops the punched part 44 from the opening of the toilet seat 3 into the toilet bowl 1, submerges it in water, and then relieves himself. At this time, the sheet paper 40 is moved to the movable plate 1 as described above.
The sheet paper 40 is held between the toilet seat 3 and the swing plate 21, so that even if the user slightly moves his or her body on the toilet seat 3, the sheet paper 40 will not shift. When the user leaves the toilet seat 3 after relieving himself,
A seating detection sensor (not shown) attached to the toilet seat 3 detects this, and this detection signal is sent to the control device S. The control device S sends a command signal to drive the cam member 15 again, and the electric motor 9 is activated, and the movable plate 10 is rotated clockwise in the opposite direction to that described above in FIG. That is, the movable plate 10 is returned from the maximum angular rotation position to the original position. As the movable plate 10 retreats, the swing plate 21 is rotated counterclockwise by the biasing force of the helical spring f about the pivots e, e in FIG. 9 to a position where it comes into contact with the stopper g. As a result, when the contact state between the movable plate 10 and the swing plate 21 is released and the sheet paper 40 is released, the sheet paper 40 is pushed into the toilet bowl 1 from the punched part 44 by the flushing water flowing into the toilet bowl 1. It is dragged in and discharged along with the cleaning water. on the other hand,
Due to the rotation of the cam member 15, the movable plate 10 passes a position parallel to the paper delivery path 42, and moves to the first position.
As shown in FIG. 0, when the movable plate 10 rotates until just before closing the paper delivery path 43, the electric motor 9 is stopped by a command signal from the control device S, and the movable plate 10 stops with the paper delivery port 43 substantially closed. After this, if you wish to continue using the Western-style toilet bowl 1, turn on the power switch 32 again and insert the sheet paper 40 into the paper feed box 4 as described above.
The required length can be derived from the above and automatically laid on the toilet bowl 3, allowing the user to use the Western-style toilet bowl 1 hygienically and with peace of mind. Next, when replacing the sheet paper 40 or when a paper jam occurs in the paper feed box 4, remove the cover 45 from the paper feed box 4, and place the hanging member 20 in front of the toilet seat 3 with the boss portions 23, 23 as the center. (see FIG. 11), and pull out the swing plate 21 and the pressing roller 7, which are disposed horizontally at the lower part between the hanging supports 22, 22, in front of the paper feed box 4. If a paper jam occurs in this state, the pressure roller 7 and paper feed roller 6 have been disassembled, so rewind the roll of sheet paper 40 a little and wrap the end around the pressure roller 7 to hang it. By returning the supports 22, 22 to their original positions, the sheet paper 40 can be easily reset. When replacing the sheet paper 40, move the support rod 24 to the left in FIG.
4, 24', and set a new sheet paper 40 in this state. Furthermore, when reusing the feeding device 2, if the cover 45 is placed on the cover 45, the hanging member 20 is received by the cover 45, and the sheet paper 40 is not broken or shaken during feeding, and the sheet can be smoothly conveyed. Paper 40 can be fed out.

【Effect of the invention】

Since the present invention is configured as described above, it has the following effects. (1) When cutting sheet paper spread on a toilet seat, the present invention uses a paper feeding roller and a pressing roller to move the sheet paper on both sides of the perforation that marks the boundary between the first sheet of sheet paper. sandwiched between the plate and the swinging plate, and
Corresponding to the rotation of the movable plate, the rocking plate is rotated in the opposite direction to the rotating plate, and at the same time tension is applied to the sheet paper, the breaking protrusion attached to the rocking plate is partially applied to the sheet paper. Since the sheet paper is directly pressed to break the sheet paper from the perforation, the cutting mechanism of the sheet paper supply device can be simplified. (2) Furthermore, the device of the present invention has a structure in which, when the movable plate rotates, the movable plate and the swinging plate that clamps one side of the sheet paper rotate against the spring member; Since the swinging plate is equipped with a breaking ridge that partially presses the sheet paper as it rotates, the work of holding and breaking the sheet paper can be done in conjunction with the driving of the movable plate. Therefore, together with the simplification of the cutting mechanism, the sheet paper can be broken quickly and easily. (3) Furthermore, the movable plate is configured to rotate the rocking plate while being hidden below the rocking plate, and the rocking plate can be rotated within a large range of motion. Therefore, even if the sheet paper is slightly slack when it is torn, the sheet paper can be broken smoothly and favorably.
