Title:
URINAL AND URINAL FLUSHING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/224190
Kind Code:
A1
Abstract:
Disclosed are a urinal and a urinal flushing control method. The urinal comprises a urinal body, a solenoid valve for starting and stopping flushing, a capacitive sensor for sensing the amount of urine on an outer wall of the urinal body, and a controller for receiving a capacitance value signal to control the turning-on and turning-off of the solenoid valve, wherein the controller sets a flush timing base point when it is determined that a capacitance value shows a downward trend after a first period of time has elapsed since the controller controlled the solenoid valve to be turned off, and same controls the solenoid valve to be turned on after the flush timing base point lasts for a second period of time. The solution can reduce the erroneous flush rate and improve the adaptability to the glaze of a urinal body.
