Control of water discharge system by reflected wave detection threshold(s)

A water discharge system comprising:

• a water discharge unit;
• a sensor unit configured to obtain a detective signal about a movement of an object to be detected through a reflected wave of a radiated radio wave;
• a control unit configured to control the start of water discharge from the water discharge unit based on the detective signal from the sensor unit;
• and
• a storage mechanics configured to store a threshold, the threshold being a determination value for controlling the start of water discharge from the water discharge unit by the control unit,
• the sensor unit being installed so that at least part of a radiated radio wave comes into contact with a discharged water flow discharged from the water discharge unit and configured to receive the reflected wave reflected by the discharged water flow,
• the control unit having a determination unit, the determination unit determining whether the discharged water is in a state of being stored in a glass or in a state in which only the start of water discharge is performed by checking a relationship between the threshold set smaller than amplitude of the detective signal in a water flow state in which only the start of water discharge form the water discharge unit is performed and amplitude of the detective signal received by the sensor unit, and
• the control unit being configured to continue the start of water discharge in case where the determination unit determines that the discharged water is in a state of being stored in a glass and to stop the start of water discharge in case where the determination unit determines that the discharged water is in a state in which only the start of water discharge is performed.

• a control unit configured to control the start of water discharge from the water discharge unit based on the detective signal from the sensor unit;
• and
• a storage mechanics configured to store a first threshold and a second threshold, the first threshold being a determination value for controlling the start of water discharge from the water discharge unit by the control unit, the second threshold being a determination value for controlling the start of water discharge from the water discharge unit by the control unit,
• the sensor unit being installed so that at least part of a radiated radio wave comes into contact with a discharged water flow discharged from the water discharge unit and configured to receive the reflected wave reflected by the discharged water flow,
• the control unit having a determination unit, the determination unit determining whether the discharged water is in a disordered state or in a state of being stored in a glass or in a state in which only the start of water discharge is performed by checking a relationship between the first threshold set larger than amplitude of the detective signal in a water flow state in which only the start of water discharge from the water discharge unit is performed and the second threshold set smaller than the amplitude, and amplitude of the detective signal received by the sensor unit, and
• the control unit being configured to continue the start of water discharge in case where the determination unit determines that the discharged water is in the disordered state and in a state of being stored in a glass, and to stop the start of water discharge in case where the determination unit determines that the discharged water is in a state in which only the start of water discharge is performed.
