Description

  The present invention relates to supplying water with a high instantaneous flow rate (flow rate) to filth present in a drainage pipe of a building, and particularly relates to a flush toilet suitable for obtaining high transport performance. It is.

As a conventional facility protection technology for drainage piping in buildings, a toilet cleaning operation that is different from normal operation is used to grasp the use status of toilets and transport filth that may be stagnant in the drainage piping. Some are controlled (see, for example, Patent Document 1).
In such a case, the stagnation in the drainage pipe can be transported to protect the facility to prevent accidents where the drainage pipe is blocked by the filth, but the meaning of why the cleaning operation was implemented. There is a problem that the user may not know or the cleaning operation is performed when the user wants to use the device, and the cleaning operation may not be performed when the user wants to perform the cleaning operation.

Moreover, when the conveyance performance defined with the defined amount of washing water cannot be satisfied, it is common to increase the stored water level in the tank or to overflow the overflow pipe by delaying the water supply stop. In order to increase the stored water level, there are some which aim to increase the water level by supplying water into the tank prior to the washing operation (for example, see Patent Document 2).
However, in this case as well, there is a limit to the increase in the transport performance that is aimed at, and there is a problem that the desired performance may not be satisfied.

Moreover, in order to update the conveyance of the stagnation in the drainage pipe, there are some that aim to improve the conveyance performance by repeating the washing operation twice at a timing different from the toilet cleaning (for example, Non-patent document 1).
However, in this case as well, it is possible to realize equipment protection to prevent accidents where the stagnation in the drainage pipe is transported and the drainage pipe is blocked by the filth, but the meaning of why the cleaning operation was implemented. There is a problem that the user may not know or the cleaning operation is performed when the user wants to use the device, and the cleaning operation may not be performed when the user wants to perform the cleaning operation.
