Description

Urinal Washing Water Discharge System {WASHING SYSTEM OF URINAL}

The present invention relates to a washing water discharge system of the urinal, and more particularly to a washing water discharge system that can effectively control the discharge of the washing water to maintain cleanliness and reduce waste of resources.

In general, the urinal includes a system that detects the user through a sensor and discharges predetermined washing water when the user is located in front of the user. Such a washing water discharge system may be manufactured integrally or separately from the urinal and installed in the urinal. Typically, the washing water discharge system is configured to achieve pre-cleaning by detecting the sensor when the user approaches, and to further discharge a predetermined amount of washing water after completion of urination. As the detection sensor, an infrared sensor or the like is usually used.

Such a discharge system has a problem of causing waste of water by discharging the washing water unnecessarily because the passage is detected irrelevant to the use of the urinal in the playful or narrow place of children.

In order to solve these problems in recent years, the use of urinals can maintain the accuracy of the timing of discharging the washing water, and at the same time, it can reduce the waste of electric power (power required to operate the washing water injection valve) as well as saving the washing water through the diversification of the discharge. Urinals are being developed.

For example, Korean Patent Application Publication No. 2006-0101901 discloses a urinal that is installed in the middle of the wall surface of the urinal and includes a wall pressure sensor that detects the impact of urine when urinating urine and controls the discharge of washing water. . These urinals have a pressure sensor installed in the urinal so that urine must be detected by the pressure sensor during urination so that washing water can be discharged, leading to saving water and accurate urine viewing, thus keeping the urinal clean. There is.

However, the urinal of this configuration is difficult to achieve the desired purpose because it is difficult to accurately detect the pressure and can not guarantee the accuracy of the urine position when the user is elderly and children, and also has a configuration that discharges the wash water every urine It is difficult to achieve the effect of resource saving.

As another example, Korean Utility Model Registration No. 20-0379754 includes a solenoid valve for electrically opening and closing a sensor and a urine washing water for detecting a human body of a urinal user, and a control unit for controlling the solenoid valve according to a detection signal of the sensor. And a power supply unit for supplying power to the electronic urinal washing valve in which the user's body is written in front of the urinal and the preliminary washing or main washing is performed according to the detection result after the detecting sensor detects the human body. Electronic control unit controls the solenoid valve operation time by checking the detection (use) time (S28), the detection (use) frequency (S29), and the detection (use) interval (S30) on the control unit that controls the solenoid valve by receiving a signal. The water saving system of the sense urinal flushing valve is posted. Such a system checks the urinal use time, the frequency of use and the interval of use, and automatically adjusts the amount of washing water according to the result, thereby saving water.

However, such a system also has a problem that the waste water is fundamentally prevented as a system for discharging a predetermined amount of washing water every time the user uses the urinal although the discharge amount is different.

The present invention has been invented in view of the problems according to the prior art as described above and the cleanliness of the urinal, to more effectively control the discharge of the washing water to minimize the discharge while maintaining the odor to keep clean and further waste of resources To provide a urine wash water discharge system that can reduce.

In order to achieve the above object, the present invention sets a constant period and starts a timer to start a cycle and at the same time to stop the washing water injection valve, and detects the presence of the user only the washing water injection valve Achievement is achieved by the urine washing water discharging system which switches to the standby mode and judges the washing water valve mode when the timer is completed and repeatedly discharges the washing water in the standby mode and resets the timer without discharging the washing water in the stop mode. Can be.

According to another embodiment of the present invention, a certain period is set and a timer is started to start one cycle, and at the same time, the washing water injection valve is set to the stop mode, and the presence of the user is detected so that the washing water injection valve is in the standby mode only when there is a user. When the timer is completed, the washing water valve mode is determined and the washing water is discharged in the standby mode, and in the stop mode, the washing water is discharged when the next user is present without the washing water discharge. It can also be achieved by a repetitive urine wash water drainage system. As in this embodiment, while maintaining the stop state without discharging the washing water at the time when the timer is completed, it is possible to reduce the waste of the washing water by discharging the washing water if there is a user.

It includes an input unit so that the administrator can directly input the cycle.

According to the present invention, instead of discharging the washing water every time the user is detected, it is discharged every certain time and the discharge is limited when the urinal is not used for a long time, which can drastically reduce the amount of washing water and save resources. Of course it is possible to have the effect of maintaining the cleanness of the urinal through regular cleaning action.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

Figure 1 is a schematic block diagram showing the device configuration of the urine washing water discharge system according to the present invention. Accordingly, the present invention includes a user sensor 20 for detecting the use of the user to transmit to the control unit 10. In addition, a timer 30 which is counted for a predetermined time and transmitted to the control unit 10 and controlled by the control unit 10 is installed. The timer 30 may be included in the controller 10 or may be configured separately from the outside according to an implementation method. The washing water injection valve 40 is to inject the washing water directly into the urinal, which is followed by the control of the controller 10. The controller 10 controls the washing water injection valve 40 in the standby mode or the stop mode according to the presence or absence of the user sensed by the user sensor 20. This can be done by specifying TRUE (true, 1) or FALSE (false, 0) for the power switch supplied to the valve depending on the presence or absence of the user. The input unit 60 provides an appropriate input means for the administrator to directly set the length of the cycle. According to the implementation method, a conventional input device such as a button, a dial, a jumper, and a dip switch may be used. And a power supply unit 50 for supplying power to the control unit 10.

Figure 2 is a flow chart showing the flow of a preferred embodiment of the urinal washing water discharge system according to the present invention. Accordingly, the present invention includes the step (S10) of setting a certain period according to the setting result of the input unit and starting one cycle by starting the timer. The cycle is usually suitable for about 1 hour to 4 hours, and fine setting of several tens of minutes is possible through the input unit depending on the implementation method.

Subsequently, the step of maintaining the washing water valve in the stop mode is performed (S20). This is done by storing a FALSE value in the controller, meaning no user. This step S20 is performed simultaneously with the start of the timer.

Next, a step (S30) of detecting whether a user is present within a corresponding cycle is performed, and if there is a user, a step of converting the washing water valve to the standby mode by storing a TRUE value indicating that the user is present (S40) is performed. The process proceeds to the next step, namely, determining whether the timer is completed (S50). On the other hand, if there is no user, the process immediately proceeds to step S50 of determining whether the timer is completed.

In the step S50 of determining whether the timer is completed, when the operation of the timer is completed, the step S60 of determining whether the washing water valve is in the stop mode or the standby mode is performed. At this time, if the standby mode to drive the washing water injection valve to perform the step of discharging the washing water (S70), in the stop mode to proceed to the next step without performing the washing water discharge step (S70).

After discharging or not discharging the washing water or performing the step S80 of resetting the timer, the cycle ends and a new cycle is started.

The present invention is to discharge the wash water at a regular cycle, but if there is no user in the cycle does not discharge the wash water at the end of the cycle, if there is a user within the cycle to discharge the wash water at the end of the cycle. In other words, for example, in general companies, public offices, and public buildings, the use of urinals is frequently used during the day, so that washing water is used at the end of each cycle. Use is limited.

Determination of whether or not the discharge by the switch value can prevent the waste of water by limiting the meaningless discharge of the wash water when there is no use of the urinal for a long time.

On the other hand, Figure 3 is a flow chart showing the flow of another embodiment of the urinal washing water discharge system according to the present invention. In this embodiment, since the step S50 of determining the completion of the timer is the same as that of the preferred embodiment, the subsequent steps will be described. In the step S50 of determining whether the timer is completed, when the operation of the timer is completed, the step S60 of determining whether the washing water valve is in the stop mode or the standby mode is performed. At this time, the step S80 is immediately performed to discharge the washing water by driving the washing water injection valve in the standby mode, and determining whether the user is present in the stop mode (S70). This user determination step S70 is executed in an infinite loop until there is a user. Subsequently, when the user is detected, after performing the step of discharging the washing water (S80) and finally performing the step of resetting the timer (S90), the cycle ends and a new cycle is started.
