Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable toilet capable of efficiently deodorizing excreted stool without leaking the odor to the outside.

[0002]

2. Description of the Related Art An elderly man who has a normal brain and can show intention to defecate but is physically weak, a disabled person or a patient due to illness or accident cannot go to a normal toilet,
A portable toilet should be used near the bed.

[0003] A portable toilet of this kind is generally a simple bucket-shaped structure for use in the immediate vicinity of a bed. Therefore, the odor of the stool excreted in such a bucket may cause discomfort to the person who cleans the stool, and may cause discomfort to other patients or caregivers due to the malodor scattered from the odor. The mental distress of those who have to use the toilets of their own will also increase. In particular, recently, when the caregiver has few hands, the toilet bowl from which stool has been excreted cannot be immediately processed, and such pain and discomfort are further increased.

Therefore, in order to reduce the odor of feces as much as possible, about half of the water is previously poured into a bucket-type container serving as a waste container, and the stool is dropped into the water. This does not completely block stool odor, and it also makes it difficult to go to the toilet because the body becomes heavy.

[0005] Recently, there is a bucket type container in which a deodorant is put in the body or a structure in which a part of stool odor is sucked. Therefore, although the effect is seen to some extent, after the stool, most of the stool odor rising from the upper opening of the container leaks to the outside, and it is impossible to completely remove the odor.

[0006]

DISCLOSURE OF THE INVENTION The present invention proposes a portable toilet which can efficiently deodorize stool excreted not only during stool but also after stool without leaking to the outside. It is.

[0007]

SUMMARY OF THE INVENTION Therefore, in the present invention, an air curtain is formed so as to entirely cover the upper opening of the body of a portable toilet with an air flow. An air suction port is opened on the side of the upper surface opening of the container to form air, and air is suctioned from the suction port by a powerful suction fan such that the air curtain can be formed. After being decomposed by an ozone generator provided in the middle of an air intake passage formed in the body and deodorized while passing through an adsorbent layer filled with an adsorbent such as activated carbon, odorless air is discharged from an exhaust port. It is discharged as. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0008]

1 and 2 show an example of a portable toilet according to the present invention, in which 1 is a body serving as a toilet body of the portable toilet, and the body 1 has an opening 2 having a substantially elliptical upper surface. A vertical cylindrical shape is formed as a whole. The base of the toilet seat 4 and the lid 5 is pivotally supported by a hinge 3 provided on the upper surface of the container 1 adjacent to one end of the elliptical opening 2 in the long axis direction, so that the toilet seat 4 and the lid 5 can be turned upside down. It has become.

Reference numeral 6 denotes a filth receiving bucket mounted so as to be removably received in a central portion of the container 1 located below the upper surface opening 2 of the container 1, and the bucket 6 is provided with an outward-facing collar at an upper edge thereof. 6a is supported by a support member 7 provided in the body 1 so as to be suspended in the body 1, and a slight space is formed between the upper surface of the bucket 6 and the upper surface of the body 1. Have been.

Reference numeral 8 denotes a horizontally elongated air suction port provided adjacent to one end of the opening 2 in the long axis direction. The suction port 8 is an air suction passage formed by partitioning the inside of the body 1. 9
And communicates with the exhaust port 10 opened on the lower side surface of the container 1.

Reference numeral 11 denotes an electric fan for air intake mounted in the middle of the air suction passage 9. The fan 11 forms an air curtain which entirely covers the upper opening 2 of the body 1 as described later. It has a strong suction force. Reference numeral 12 denotes an adsorbent layer provided in the middle of the air suction passage 9 below the electric fan 11, and for example, a replaceable activated carbon cartridge filled with activated carbon is used. Reference numeral 13 denotes an ozone generator arranged above the intake fan 11.

Although not shown, the suction fan 11 and the ozone generator 13 of the portable toilet are operated by an external power supply and are turned on / off by operating a switch (not shown). When the user sits on the toilet seat 4, the switch is automatically turned on by its own weight, and the switch is not switched off for a predetermined time even when the user leaves the toilet seat 4.

The toilet seat 4 is laid down and seated on the toilet seat 4 for use, and the fan 11 and the ozone generator 13 are operated. Since the upper surface opening 2 of the container 1 is closed by the user's hip, the air in the inner waste receiving bucket 6 is sucked from the suction port 8 on the side of the upper surface opening 2 and passes through the air suction passage 9. A forced airflow exhausted from the lower exhaust port 10 will be generated.

Therefore, the waste 1 excreted in the bucket 6
The odor emitted from 4 is guided into the suction passage 9, decomposed by the ozone of the ozone generator 13, and subsequently deodorized while passing through the adsorbent layer 12 such as activated carbon. Released.

The fan 12 continues to operate together with the ozone generator 13 even after the toilet and the toilet seat 4 have been separated. As described above, the electric fan 11 for suction has a strong suction force capable of forming an air curtain by an air flow that entirely covers the upper opening 2 of the body 1, and therefore, the bucket 6 after leaving the toilet seat. The odor from the waste 14 inside is completely shut off by the air curtain and does not leak to the outside.

Since the waste receiving bucket 6 is merely suspended in the container 1, the bucket 6 can be taken out, the waste 14 in the bucket 6 can be discarded and the bucket 6 can be easily cleaned. That is.

[0017]

As described above, the portable toilet of the present invention has an air curtain formed by the air flow directed to the air suction port over the entire opening of the upper surface of the body. Unlike the case where most of the odor of feces leaks to the outside just by sucking a part of the stool, the odor of the stool excreted in the waste receiving bucket is completely shut off by the air curtain without leaking to the outside. Therefore, it is not necessary to put water or a deodorant in the bucket, and it is possible to efficiently deodorize.
