  Water saving system for electronic urinal flush valve

  The present invention relates to the water-saving system of the electronic sensing urinal washing valve,

Water to automatically adjust the washing flow rate according to the urine time and the number of urinals used

It's about the system.

  The electronic sensing urinal washing valve is generally a public toilet as shown in FIG.

Installed in the urinal 200, the user usually writes the sensor 21 in front of the urinal 200

Detects the user's human body and reduces the smell of urine after a certain time

A small amount of washing water to form a water film in the urinal 200 to increase the urinal washing effect

A pre-wash to allow water discharge is executed and the user withdraws from the urinal 200 after the urine is finished.

Afterwards, it moves away from the detection area of the detection sensor 21 and it is an electronic urinal.

The washing valve 100 determines that the user has finished urine, and the urinal 200 in earnest.

It is configured to carry out the main washing.

  Figure 4 is a flow chart of the operation of the conventional electronic sensing urinal washing valve.

This will be described in detail with reference to FIGS. 2 and 3 as follows.

Step S10 transmits and receives a detection signal and checks for the presence or absence of the detection signal so that the detection signal is maintained for more than T0.

If it is detected, it is determined whether it is detected to perform the control of the next step.

The solenoid is turned on to open the water supply valve and flushing water flows into the urinal.

Step S12 checks the washing time (T1) of pre-washing, and after the pre-washing time has elapsed, in the next step S13, the solenoid power is turned off to close the water supply valve to flush the washing water.

Pre-cleaning is done.

Step S14 continuously checks the detection state and when the detection is terminated, in step S15

Turn on the solenoid and open the water supply valve to drain the washing water.In step S16, check the main washing time (T2) .After the main washing time, turn off the power of the solenoid in step S17, close the water supply valve, and flush the washing water. Of washing is completed

will be.

  However, such a conventional urinal flushing valve has a washing time of pre-cleaning and main washing.

Each time it is used, only the same flow rate or the control time

It is made by manual operation by separately installing timer control device

Regardless of where the urinal is used or where it is used, the same flow rate is always discharged

In addition, regardless of the amount of urine is low and always discharged at the same flow rate

It is difficult to expect a water saving effect.

  This paper solves the problems of the conventional electronic sensing urinal washing valve as described above.

Especially when there is a lot of urine use and when there is a lot of urine

Urine discharge rate is automatically adjusted according to the urine use condition

It is to provide an electronic sensing urinal cleaning valve with a very high water saving effect.

  Electronic sensing urinal washing valve of the present invention for achieving the above object

The water saving system will be described with reference to FIGS. 2 and 3 as follows.

If the detection signal from the detection sensor is over T0 hours, the controller

Recognize and open solenoid valve to perform prewash (T1) and allow the user to urinate

After leaving the urinal, the sensor will be detected and the main cleaning (T2)

In the electronic sensing urinal washing valve cleaning system

The washing time of the main cleaning (T2) is detected by the control unit between the detection time (Tt) and the previous detection time.

Checking the time interval (Td), based on the checked data as the use time and the number of times

The washing time shown in the main table item of the main washing time table of FIG.

The urine volume is high when there is a lot of urine use and a little, so that it is washed according to an example

The urine water discharge rate is automatically adjusted according to when and when it is used.

Electronically sensed urinal flush valves can be provided.

  Here, the sensing recognition time (use time) Tt shown in the main washing time table of FIG.
