Problems solved by technology

The above judgment logic is likely to cause misjudgment and false alarm when the urinal stops water
In addition, when installing a urinal, generally power on and control the solenoid valve to open and close once before passing water, which is also likely to cause false alarms

Abstract

The invention discloses a urinal, blockage determination method, alarm method, and flushing control method. In the blockage determination method, the condition of whether a capacitance value increasesor not after a solenoid valve is opened is introduced to avoid misjudgment and false alarm of blockage caused by interruption of water supply of the urinal due to the fact that only the change condition of the capacitance value after the solenoid valve is closed is judged.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a urinal and a blockage judging method, an alarm method and a flushing control method. Background technique [0002] Existing urinals with capacitive sensing control function compare the capacitance value collected for a period of time after the end of flushing with the capacitance value at the end of flushing. If the difference is low, it is judged as blocked and an alarm is issued. The above judgment logic is likely to cause misjudgment and false alarm when the urinal is without water. In addition, when installing a urinal, it is generally necessary to power on and control the solenoid valve to open and close once before passing water, which is also likely to cause false alarms. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects or problems in the background technology, and provide a urinal and a clogging judging met...
