Then, the part of the air and the remaining air merge, enter the exhaust pipe 62 from the discharge flange 58b, and are sequentially guided to the exhaust passage 60. Then, the air is filtered by an element 87 in a filter 85 provided in the middle of the exhaust passage 60, guided to the exhaust pump 80, and further discharged through the exhaust passage 60 to the outside of the toilet 1.

The operation when the used toilet papers A are inserted from the input port 56 will be described below.

First, the user wipes the stool or the like with toilet paper in the toilet. Then, without putting the used toilet papers into the toilets 6 and 7,
It is put into the inlet 56 of the toilet paper collection device 50. That is, when the user pushes down the opening / closing lid 57 downward (turns clockwise in FIG. 3) against the elastic force of the return spring, the opening / closing lid 57 opens, and the toilet paper A is discharged from the insertion port 56. Since it becomes possible to insert the used toilet paper A into the opened input port 56,
Into the collection container 51. At this time, the suction force of the exhaust pump 80 acts on the input port 56, and air flows from the toilet room 5 into the collection container 51. The flow becomes a suction force, and the toilet paper A Is positively guided into the collection container 51, in particular, into the collection bag 70. The toilet papers A are stored at the bottom of the collection bag 70. Used toilet paper A from the input port 56
Are sequentially charged, and are sequentially stored at the bottom of the collection bag 70. Since the toilet papers A are relatively large, they do not flow out of the small holes 71 opened on the bottom surface of the collection bag 70.

When the above insertion is completed, the user releases the lowering of the open / close lid 57. The opening / closing lid 57 closes the insertion port 56 by the elastic force of the return spring.
Although the suction of air from the inlet 56 into the collection container 51 is stopped, the exhaust pump 80 is driven even after the opening / closing lid 57 is closed, so that the small hole 5 formed in the side surface of the container outer tube 53 is opened.
The flow of air from 3a into the collection container 51 is still maintained. Therefore, fresh air in the toilet room 5 is sucked into the collection container 51, and the backflow thereof is prevented.

As described above, since the suction force of the exhaust pump 80 always acts on the collection container 51, even if odors come out of the stored used toilet paper, the collection container 5 can be used.
1 is not released into the toilet room 5. In addition, since fresh air is always introduced into the collection container 51, odors from toilet papers are less likely to occur.

When the toilet papers A are sequentially inserted from the inlet 56 and the collection bag 70 is filled with the toilet papers A, the lid 55 is removed and the opening flange 72 of the collection bag 70 is pulled up. The collection bag 51 is taken out of the collection container 51, and then the opening flange 72 of the collection bag 70 is closed to seal the inside. In this state, it is transported to a waste disposal site or an incineration plant, and is buried or incinerated integrally. Since it can be carried out to these disposal sites or incineration plants in a sealed state, it is difficult for the odor to be released to the outside during that time.

Next, referring to FIG. 7, a collection container 151 of the toilet paper collection device according to the second embodiment will be described.

Is supported by the lid 155 in a cantilever manner. The rubber closing plate 157 has flexibility, and when used toilet papers A are inserted into the inlet 156, the rubber closing plate 157 bends downward and can open the opening. This is to allow the toilet papers A to be easily inserted at the time of insertion, but to be immediately closed after the insertion.

In this embodiment, even when the toilet paper A is not inserted into the input port 156, the rubber closing plate 157 can be used.
Has a small-diameter opening at the tip of the inner diameter. For this reason, even when the pump is not turned on, the suction force from the exhaust pump is applied to the inlet 15
6, the air is sucked into the collection container 151 from the inlet 156 in addition to the path from the small hole 153a opened on the side surface of the container outer tube 153. Therefore, the input port 15
Even if 6 is always open in the toilet room 5, the exhaust pump 1
Due to the inhalation action of 80, an air flow is always formed in the direction from the charging port 156 to the inside of the collection container 151, so that the stool attached to the used toilet paper A in the collection bag 170 does not easily emit an odor. Also, even if it is released, a bad smell,
Since there is no backflow from the inlet 156 to the toilet room 5, no odor is released into the toilet room 5. Since the other structure is the same as that of the first embodiment, the same portions are denoted by reference numerals obtained by adding 100, and description thereof will be omitted.
