Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for emitting a flushing sound of a flush toilet to eliminate physiological sounds.

When using a toilet, especially a public toilet, some people flush the water from the time they enter the toilet until they exit because they are embarrassed to have their menstrual sounds heard by others, resulting in wasted water.

This invention solves the above problems, and its purpose is to generate a simulated flushing sound in a flush toilet and eliminate the menstrual sound before the simulation, so that flushing is performed only after the physiological phenomenon has passed. To provide a physiological sound canceling device capable of saving water in this manner.

The present invention will be described below based on embodiments shown in the accompanying drawings.

As shown in the figure, a locking device 3 for a door 2 is provided inside the toilet 1 so as to be operable from inside. This locking device 3 is
A locking piece 4 is fixed to the main body of the toilet 1, a δI movable piece 5 that allows the locking piece 4 to be moved in and out is attached to the door 2, and the movable piece 5 is configured to be interlocked with an operating lever 6. Therefore, when the operating lever 6 is operated to insert and lock the movable piece 5 into the locking piece 4, the locking device 8 is locked, the door 2 is locked, and the movable piece 5 is released from the locking piece 4. When this is done, the lock device 3 is unlocked and the door 2 can be opened and closed.

A detector °r is provided near the locking device 3 to detect whether the locking device 3 is locked.

This detector "r" is shown in Figures 1 and 2 as a limit switch that contacts the movable piece 5 and closes one point of contact, but a magnet is provided on the movable piece 5 and this magnet is detected. It may be a proximity switch such as a magnetic sensor, or it may be a contact type or non-contact type as long as it can detect whether the locking device is locked.

Further, as shown in FIG. 3, a pseudo-sound generating device 8 that emits a pseudo-flushing sound of a flush toilet is supplied with power via the detector ゛r and the manual switch 9.

Therefore, when both the detector "r" and the manual switch 9 close their contacts, the pseudo sound generating device 8 is energized and emits a pseudo sound of flushing, so that even if the user urinates or the like, physiological sounds are erased.

The pseudo-sound generating device 8 may be a tape device using endless tape, but it can be made smaller by configuring it with an electronic circuit using an integrated circuit ROM (read-only memory), a sound generating element, etc. It is desirable to do so. Further, the manual switch 9 is operated when the toilet user does not want to activate the pseudo sound generating device 8 and is not necessarily required, but if it is installed, it can be easily operated near the toilet paper support 10. It is desirable to have it in place.

Note that the locking device 3 is not limited to the embodiments shown in FIGS. 1 and 2, and may be other locking devices such as a locking device having a rotatable movable piece. The detector 7 may be formed integrally with the lock device 3.

As described above, the present invention includes a detector that detects the locking of the door, and when the door is locked, the pseudo sound generating device is activated to generate a pseudo flushing sound. Therefore, physiological sounds such as urination are canceled out by the pseudo sounds without flushing the water in the flush toilet, so there is an advantage that water can be saved because the water only needs to be flushed after the physiological phenomenon has finished.

Further, if the pseudo sound generator is activated by locking the door, it is possible to prevent forgetting to lock the door.
