Description

The present invention relates to an excrement disposal method and a device thereof that can be moved closer to the user and used as a chair-type toilet bowl, and can also be set in the crotch of a bedridden user and used as an insertion toilet seat.

Conventionally, various portable toilets that can be moved near the user and used as a chair-type toilet have been known.
Patent Document 1 describes a portable toilet for the purpose of requiring less washing water for a toilet bowl.
This portable toilet has a movable working base, a toilet bowl installed on the working base, a bucket placed on the lower side of the toilet bowl, a toilet seat placed on the upper side of the toilet bowl, and the toilet. It has a means for supplying pot washing water to the pot, and the toilet bowl washing water supply means is arranged at the rear of the toilet bowl and includes a spray nozzle for spraying water toward the inside of the toilet bowl, and is provided in the tank. Water is supplied to the spray nozzle via a pipe, a pump, a three-way switching valve, and a pipe, and the water in the tank is made hot water through a pipe and a heater branched from the three-way switching valve, and the hot water cleaning nozzle is used. Supply to. After sitting on the toilet seat and performing stool, the buttocks are dried with a warm water washing nozzle. After that, water is sprayed from the spray nozzle to wash the toilet bowl. Since water is sprayed from the spray nozzle to wash the toilet bowl, the amount of water used is small, and the number of times the bucket is washed and the tank is filled with water is small.

Patent Document 2 describes a sewage pot having an upper stool pot portion and a lower sewage storage tank, and secures a seal to prevent odor leakage when the lid is closed at the lower end of the stool pot portion. What to do is described.
In order to achieve this purpose, the sewage pot is provided with an upper stool pot portion, a container-shaped lower sewage storage tank, and a lid for closing the opening at the lower end of the stool pot portion. Then, a tapered female fitting surface is formed on the inner peripheral surface of the opening, and a male fitting surface that fits the female fitting surface is formed on the lid so as to fit them. Moreover, the male fitting surface of the lid is configured to be a surface having a steeper angle than the taper angle of the female fitting surface of the opening.

Further, Patent Document 3 describes an excrement treatment device that can be set in the crotch of a bedridden user and used as an insertion toilet seat.
This excrement treatment device applies an insertion toilet seat to the crotch of a bedtime user, covers the insertion toilet seat with a diaper, sucks the excrement excreted in this insertion toilet seat into the sewage tank of the main body of the excrement treatment device, and sewage. When the tank is full, it is separated from the main body of the excrement treatment device and transported to the toilet bowl connected to the sewer pipe for pouring.

JP-A-2002-45307. Japanese Unexamined Patent Publication No. 2002-20005 Japanese Patent No. 5254498

The device shown in Patent Document 1 cleans the buttocks and the pot with a spray nozzle after excretion, but the excrement is stored in a bucket installed under the toilet bowl and only covered with a lid, so that it has an odor. There was a problem that it could not be suppressed from diverging to the outside.
The device shown in Patent Document 2 describes that the opening between the toilet pot portion constituting the filth pot and the filth storage tank below the sewage pot is covered with a lid having a tapered male-female fitting surface. There was a problem that the emission of odor during defecation could not be suppressed.
Since the device shown in Patent Document 3 sucks the excrement excreted in the insertion toilet seat into the sewage tank of the main body of the excrement treatment device, there is almost no leakage of odor from the insertion toilet seat, but it is excreted when the sewage tank is full. It is separated from the main body of the material processing device and transported to the toilet bowl connected to the sewer pipe for pouring.
Therefore, in all of the references shown in Cited Documents 1, 2 and 3, when the excrement is full in the bucket or the sewage tank, the bucket is carried to the toilet bowl connected to the sewer pipe, poured into the sewage, and the bucket is filled. There was a painful task of having to clean the toilet.

A first object of the present invention is to provide a sewage tank that can be directly pumped and discharged to a sewer pipe by compressed air from a main body of an excrement treatment device when the sewage tank is full.
A second object of the present invention is to provide an excrement treatment device that can be used as a chair-type toilet bowl and can also be set in the crotch and used as an insertion toilet seat.
Still other objects of the invention will be apparent from the description in the specification and the drawings.
