Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a toilet device used in a weightless space such as a space station.

(Background of Invention and Prior Art) With the remarkable development of aerospace science in recent years, it is expected that humans will live in a weightless space such as a space base in the not-so-distant future.

As is well known, since an object is in a weightless state where the atmosphere outside the atmosphere can be ignored, if left unattended, it floats in the air, and water and the like become small spherical particles and float.

This is also true of human excrement, and therefore, it is expected that how to treat excrement becomes a major issue when humans live in such a weightless state. It is a place.

That is, since the excrement does not naturally fall due to gravity in the forceless space, it is not possible to properly excrete excrement waste from the toilet bowl with the conventional toilet device that is premised on use under the condition that gravity acts. Not only that, but there is also the danger that filth will float and scatter in the space.

Therefore, there is a demand for the development of a toilet device that can properly excrete excrement even in a zero-gravity space, but such a toilet device has not yet been developed.

(Problems to be solved by the invention) The present invention has been made in view of the above situation, and the purpose of the invention is to apply a suction force to the excrement waste and a pressing force to push the excrement waste in the suction direction. It is to pack the product smoothly without discharging it in the air and to easily post-process waste excrement.

(Means for Solving Problems) The technical means taken by the present invention to solve the above problems is to connect the defecation port of the toilet to the waste storage space provided with the suction device and to provide air to the upper part of the toilet. An insulting guide tube which is provided with the insufflation part facing downward, communicates with an air supply device to the insufflation part, and which communicates with the excretion opening in the middle of the toilet in correspondence with the excretion hole formed in the seat of the toilet. And a long ventilation waterproof bag covering the lower end opening of the excretion guide cylinder is provided on the outer periphery of the excretion guide cylinder in a folded state, and the delivery mechanism for delivering the bag by a predetermined length is provided. The gist is that a heat seal device is provided adjacent to the excretion guide tube portion, and a heat seal device for heat sealing the delivered bag is provided at a lower level of the delivery mechanism.

(Operation) Therefore, according to the above technical means of the present invention, the flow of the air flowing toward the defecation port is generated in the toilet bowl by the suction force of the suction device and the pushing force of the air blown from the upper part of the toilet bowl. , The excrement waste gets on the flow of the air and stays in the bag discharged downward by the discharge mechanism at the discharge guide cylinder, and is post-processed in the sealed bag cut by the heat seal device. Packed in a pack. The packed excrement waste is smoothly sent to the waste storage space by the suction force and the pushing force.

Further, since it is heat-sealed, the bottom portion of the bag provided so as to cover the lower end opening of the excretion guide cylinder is also hermetically sealed and serves as a receiving portion for the next excrement waste.
