Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for eliminating water (changes) that bounces off a water surface when a toilet is used.

[0002]

2. Description of the Related Art It is known that a water-soluble paper is floated on the water collecting surface of a toilet bowl to eliminate the change when the toilet bowl is used (Japanese Utility Model Laid-Open No. 10573/1993).

[0003]

The publication does not disclose a device for supplying a paper piece to a toilet bowl.

The present invention provides a toilet bowl anti-removal device for supplying a toilet bowl with a necessary and sufficient amount of paper pieces so as to surely prevent a change.

[0005]

According to a first aspect of the present invention, there is provided a change prevention device for a toilet bowl, which is an apparatus for supplying a water-soluble paper piece to the water collecting surface of the toilet bowl, and a holder for holding a continuous paper sheet of water-soluble paper. It is characterized in that it is provided with a paper feeding device for feeding the paper from the holder and a cutting device for cutting the fed paper into a predetermined size.

According to a second aspect of the present invention, there is provided the toilet bowl change prevention device according to the first aspect, wherein the cutting device cuts the paper into minute pieces.

According to a third aspect of the present invention, there is provided the toilet bowl change prevention device according to the first aspect, wherein the cutting device cuts the paper into substantially the size of the pool surface.

[0008]

By feeding a continuous paper of water-soluble paper into a predetermined size while sending it out by the paper feeding device, it is possible to reliably supply the anti-hanging paper piece to the toilet bowl.

This piece of paper may be a minute piece or may have a size of the accumulated water surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing a toilet bowl change prevention device according to an embodiment, FIG. 2 is a sectional view taken along line II-II in FIG. 1, and FIG. 3 is a perspective view of a cut roller. FIG. 4 is a perspective view of a Western-style toilet provided with a toilet bowl change prevention device according to an embodiment.

As shown in FIG. 4, a toilet seat box 3 is installed on the rear upper surface of the toilet bowl 2 of the Western-style toilet 1, and the toilet seat 4 and the toilet lid 5 are installed.
Is pivotally attached. A low tank 6 is installed behind the toilet seat box 3.

As shown in FIG. 1, the toilet seat box 3 has a step portion 7 on the left side when viewed from the front side of the upper surface thereof, and a cover 8 is detachably attached to the step portion 7. A shaft 10 for supporting the roll body 9 of the toilet paper is horizontally projected from the side surface of the step portion 7, and the roll body 9 is rotated by inserting the shaft 10 into the center of the roll body 9. Freely supported. A cap 11 for detaching the roll body 9 is detachably attached to the tip of the shaft 10.

On the upper surface of the step portion 7, an insertion port 12 for the toilet paper unwound from the roll body 9 is provided in an elongated slit shape. An opening 13 is provided in the lower part of the front surface of the toilet seat box 3 for feeding the paper piece into the toilet bowl 2.

As shown in FIG. 2, in the toilet seat box 3 below the step 7, a cut roller 15 and a rubber guide roller 16 are arranged below the insertion port 12 so that their axes are parallel to each other. The blade 15a on the outer peripheral surface of the cut roller 15 is provided so as to contact the outer peripheral surface of the guide roller 16.

Below the rollers 15 and 16, a belt conveyor 17 for sending the paper piece to the opening 13 is installed.

The blade 15a of the cutting roller 15 is a combination of a plurality of straight blades and circular blades arranged in a cross pattern as shown in FIG. 3, and the toilet paper 9 sandwiched between the rubber guide roller 16 and the outer peripheral surface thereof. Has a function of cutting into small square paper pieces 19.

In the toilet seat box 3, the cut roller 1
5, a motor for driving the guide roller 16 and the conveyor 17, and a control unit (not shown) are installed. A manual switch 18 provided on the side surface of the toilet seat box 3 and a seating sensor (not shown) provided on the toilet seat 4
Are connected to the control unit. The control unit controls the operation of the rollers 15 and 16 and the conveyor 17.

In the toilet bowl change prevention device thus constructed, the cover 8 is removed and the toilet paper 9 is used.
Insert the inner core into the shaft 10, fit the cap 11, unwind the tip of the toilet paper 9, and insert the outlet 1
Plug in 2. When switch 18 is pressed, rollers 15 and 1
6 and the conveyor 17 are operated for a predetermined time. Roller 1
The paper piece 19 finely cut between 5 and 16 is the conveyor 1
It is conveyed to the opening 13 by 7 and falls from the opening 13 into the toilet bowl 2. The dropped paper piece 19 floats on the water surface in the toilet bowl 2.

By suspending a sufficient amount of paper pieces on the surface of the accumulated water, it is possible to prevent change when the toilet is used.

Even when the user sits on the toilet seat 4 without operating the switch 18, the rollers 15 and 16 and the conveyor 17 are operated for a predetermined time by the signal from the seating sensor, and similarly, the piece of paper enters the toilet bowl 2. Supplied.

FIG. 5 is a sectional view showing an apparatus of another embodiment. A pair of rubber guide rollers 2 is provided below the insertion port 12.
0, 21 are arranged, a cut roller 22 and a rubber guide roller 23 are arranged below the cut roller 22, and a pair of rubber guide rollers 24, 25 are arranged obliquely below the cut roller 22. Reference numerals 26, 27 and 28 denote guide plates. On the outer peripheral surface of the cut roller 22, one straight blade 22a extending in a direction parallel to the axis of the cut roller 22 is provided. The outer peripheral surface of the cut roller 22 is in contact with the outer peripheral surface of the guide roller 23.

Other configurations in FIG. 5 are the same as those in FIG. 2, and the same reference numerals indicate the same parts.

5, the toilet paper unwound from the roll body 9 is pulled downward by the cut rollers 20 and 21 through the insertion port 12 and further the rollers 22 and 23. , 24, 2
5 and the guide plates 26, 27 and 28 to reach the opening 13. When the cutting roller 22 makes one rotation, the straight blade 22a comes into contact with the roller 23 and the toilet paper is cut. The rollers 20, 21, 22, 23 are stopped immediately after this cutting. The rollers 24 and 25 continue to rotate, and the cut piece of toilet paper 30 is cut by the roller 2.
It will be stopped when it passes 4,25.

The length of the outer circumference of the cutting roller 22 is selected so that the cut toilet paper piece 30 just covers the water surface of the toilet bowl 2 (for example, about 10 cm). Therefore, the paper piece 30 sent out from the opening 13 falls in the toilet bowl 2 and covers almost the entire surface of the accumulated water. As a result, change of the Western-style toilet 1 during use is prevented.

Although the toilet paper is cut by the cutting rollers 15 and 22 in the above-described embodiment, various cutting devices such as one that cuts by reciprocating a flat blade tool in a direction perpendicular to the paper surface can be used.

In the toilet bowl change prevention device of FIGS. 1 to 4, the cut roller 15 is operated so that a required amount of cut paper pieces are accumulated on the conveyor 17, and when the switch 18 is operated or the toilet seat 4 is operated. Conveyor 17 when seated
It is also possible to operate only the above to supply the paper pieces to the toilet bowl 2.

In the above embodiment, the change prevention device is installed in the toilet seat box 3, but in a Western-style toilet of the type in which the low tank is surrounded by a cover, the change prevention device may be installed in this cover.

[0028]

As described above, according to the change prevention device of the present invention, it is possible to surely prevent change by supplying the necessary and sufficient amount or size of the paper piece to the pool surface.
