Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a water storage surface holding structure for a toilet.

(B) Conventional technology Conventionally, in flush toilets, a stool-type toilet has a certain amount of stored water in a toilet bowl, and sedimentation of filth associated with defecation is carried out in the stool, and odors are generated from the filth. It is configured to prevent divergence.

(C) Problems to be Solved by the Invention However, since there is a certain space between the water level of the water surface stored in the toilet bowl and the buttocks of the human body, dirt discharged into the toilet bowl cannot be removed. Before the water is stored, the odor of the filth is released, and the odor goes out of the toilet bowl.

Therefore, in such a toilet bowl, in order to prevent the odor from spreading to the water storage, the water storage level in the toilet bowl is set as high as possible, and the space between the butt of the human body is made as large as possible. There is a method to reduce the number.

However, even when the water level in the toilet bowl is raised to a high position, the trap that communicates with the outlet at the bottom of the toilet bowl is not located at the high position, so the water level in the raised toilet bowl is maintained. There were drawbacks that could not be done.

In addition, in order to eliminate such a drawback, the water level of the trap formed at a high position can maintain the water level in the toilet bowl at a high position. There is a disadvantage that the discharge efficiency is deteriorated.

(D) Means for Solving the Problems The present invention relates to a toilet bowl in which a flushing outlet provided at a lower part of a toilet bowl is connected to a drain pipe through a trap that rises up and down the middle. An openable and closable lid that can close the trap passage in the trap ridge is provided, and when the waste is discharged, the opening of the trap ridge is opened, and when the waste is not discharged, the opening of the trap ridge is closed.
An object of the present invention is to provide a toilet-water-holding-surface holding structure, which is configured to be able to hold a water-holding surface in a toilet bowl in a raised state.

In addition, the trap raised bottom portion is formed so as to be movable up and down, so that when the waste is not discharged, the raised bottom portion is moved upward so that the water storage surface in the toilet bowl can be maintained in a raised state. Has features.

(E) Function and Effect (1) In the present invention, the trap ridge is provided with an openable and closable lid capable of closing the trap passage, and when the waste is discharged, the opening of the trap ridge is opened. Because the opening of the protruding part is closed so that the water storage surface in the toilet bowl can be maintained in a raised state,
When the waste is not discharged, the water level in the toilet bowl can be kept as high as possible by closing the opening of the trap ridge. Therefore, when the user sits on the toilet bowl, the water in the toilet bowl becomes as close as possible to the buttocks, so that the contact time between the waste and the air that is discharged is short, and the odor from the waste is released. Can be prevented.

Further, at the time of discharging the waste, by opening the opening of the trap ridge, the discharge of the waste can be performed smoothly as in the conventional method using the siphon phenomenon.

(2) In the present invention, the raised bottom surface of the trap is formed so as to be movable up and down. Therefore, when waste is not discharged, the raised floor surface of the trap is raised to raise the water storage level in the toilet bowl as much as possible. Can be held at the water level. Therefore, when the user sits on the toilet bowl, the water in the toilet bowl becomes as close as possible to the buttocks, thereby shortening the contact time between the discharged waste and the air, and reducing the odor from the waste. Divergence can be prevented.

Further, at the time of discharging the waste, the waste can be discharged smoothly by descending the trap raised bottom portion in the same manner as the conventional method by the siphon phenomenon.
