Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to a flush water discharge device that is particularly suitable for flush toilets that are installed in large numbers.

Conventional technology: There are two types of flushing water discharging devices for flush toilets: one is of a tank volume dependent type that discharges a predetermined amount of flushing water depending on the volume of the cistern, and the other is of a tank volume dependent type that discharges a predetermined amount of flushing water depending on the structure of the discharge valve. There is a type that depends on the valve structure for discharging water, and both are widely adopted.

Problems to be Solved by the Invention: The above two types each have advantages and disadvantages. In other words, the tank volume-dependent type has the advantage that the discharge amount does not change over time, but on the other hand, it is subject to restrictions due to the installation position of the drain pipe and the structure of the toilet bowl.On the other hand, the valve structure-dependent type This has the advantage of not being subject to the limitations associated with tank volume dependent types, but on the other hand, it is more likely to change over time. Furthermore, in the tank volume dependent type, the discharge h''C is not affected by changes in the water pressure, but in the valve structure dependent type, the discharge fi1 is affected by changes in the water pressure.This point is dependent on the tank volume. The presence of a cistern in the toilet compartment is one of the advantages of this type, but it can be said to be one of the disadvantages of the 7° tank volume type.

Means for Solving the Problems: The present invention solves the problems in the book [1].
According to the present invention, a water meter is provided in a pipe line between a discharge valve and a toilet bowl connected to a water pipe for supplying flush water, and
The present invention is characterized in that a valve-closing device is provided for shifting the discharge valve, which is in the open state, to the closed state when the wash water flow rate bk measured by the water meter reaches a predetermined value.

Function: The water meter installed between the wash water discharge valve and the toilet bowl is one element of the mechanism that closes the discharge valve opened by the operation performed by the toilet user, and emits a signal to close the discharge valve. Sends to valve control device. This mechanism works by recognizing that a predetermined amount of flushing water has been supplied to the toilet bowl, rather than assuming it as a fact. Since flushing water is discharged using water pressure,
There are no restrictions on the type of toilet bowl or the installation of drain pipes.

On the other hand, the discharge amount does not depend on the estimation that this amount should have flowed due to the structure of the discharge valve.

Example: FIG. 1 shows an example of a washing water discharge device according to the present invention.

In this figure, 1 is a toilet bowl, 2 is a toilet room, 3 is a door of the toilet room, 4 is a wash water discharge switch provided in the toilet room 2,
5 is a drain pipe. The drain pipe 5 is provided above the floor 7 in the space behind the rear wall 6 of the toilet room 2. 8 is a water meter, 9 is a discharge valve, and the water meter 8 is provided on a flow path lO between the discharge valve 9 and the toilet bowl 1. Various types of water meters 8 can be adopted, but the one shown in the figure is of a blade wheel type, and the rotation of the blade wheel is controlled by a reduction gear l! Rotating disk 1 via
2 can be conveyed. The reduction ratio of the reduction gear 7111 is selected so that the rotation angle of the rotating disk I2 that occurs when a predetermined amount of washing water is discharged is within 360 degrees.

FIG. 2 is a plan view showing a group of glue switches 13 arranged around the rotating disk I2 and a permanent magnet 14 attached to the rotating disk 12.

The reed switch 13 is provided on the ring body 15. The reed switch 13 of the ring body 151 in a stationary state and the permanent magnet I4 of the rotary disk 12 form a valve closing signal generator for the discharge valve b9. ÷ is the control device for the discharge valve. The control device 16 is provided with a rotation angle setting section (discharge amount setting section) of the rotating disk 12, and when a predetermined amount of cleaning water is discharged, the ring body 15 facing the permanent magnet I4 on the rotating disk 12 is installed. The signal from the upper reed switch 13 is taken as valid, and the discharge valve 9 is shifted from the open state to the closed state.

The rotation angle setting section of the rotary disk 12 has settings for the use of the toilet.
A first system for large children and a second system for small children who use the toilet are provided.

The rotation angle set for the rotating disk 12 is 180 degrees when the toilet is used for "large" and 45 degrees for "small", or 90 degrees for "large" and 90 degrees for "small". In some cases, it is assumed to be 30 degrees. These values are related to the required discharge amount of wash water and the reduction ratio of the reduction gear device 11. Reference numeral 17 denotes a bypass flow path for use in the event of a power outage or failure of the control device 16 or the like (see FIG. 1), and this flow path is provided with a discharge valve 18 that is manually opened from the toilet side.

Note that 19 is a signal when the use of the toilet is [large], and 20 is a signal when the use of the toilet is ``tJz j''.

Effects of the Invention: The present invention provides a flush water discharge device for a flush toilet in which the amount of discharged water at one time is hardly affected by the structure of the discharge valve or the water pressure. The present invention provides the advantages of the two types, namely, the tank volume dependent type and the valve structure dependent type, while avoiding their disadvantages.
