For example, setting the first, second, third, fourth, and fifth set values, the flow rate of the inductive water supply device can be from the first, second, third, and fourth levels. Gradually increase to the fifth level, and then the fifth, fourth, third, and second levels are reduced to the first level, and are repeated. For example, if the first level is set to 10 liters/minute, and each level is increased by 2 liters/minute, the first level is the lowest set value of 10 liters/minute, and the fifth level is the highest set value of 18 liters/minute.

The fourth embodiment is a temperature control mode: Referring to FIG. 6d, when the inductive water supply device 100 continues to supply water (for example, the inductive water supply device 100 first enters the water supply state of the switch control mode in the first or second embodiment) And the third sensing signal is a temperature increasing signal when the third sensor 122c senses that the foreign object (for example, the hand 104) appears for more than a third time (for example, can be set to 3 seconds). Or a temperature reduction signal, the temperature of the feed water of the inductive water supply device 100 is continuously increased or decreased; and when the temperature of the feed water of the inductive water supply device 100 is continuously increased or decreased, and only the third sensor 122c senses When the disappearance of the foreign object exceeds the third time, the third sensing signal is a temperature maintenance signal, so that the temperature of the feed water of the inductive water supply device is maintained. For example, the first microprocessor 132 receives the temperature increase signal, the temperature decrease signal or the temperature maintenance signal to generate a control signal, and the second microprocessor 142 receives the control signal to generate a drive signal, and the driver 152a according to the The valve group 154a is driven by a drive signal for controlling the feed water temperature of the inductive water supply device 100.

The mode of continuously increasing or decreasing the temperature of the feed water of the inductive water supply device is set by a plurality of set values, and the temperature of the feed water of the inductive water supply device is gradually increased from a minimum set value to a highest set value, and then the highest set value is used. Gradually reduce to the lowest setting and repeat. For example, set level 1, 2 Level, level 3, level 4 and level 5 settings, the temperature of the feed water of the inductive water supply device can be gradually increased from the first level, the second level, the third level, the fourth level to the fifth level, and then From the fifth, fourth, third, and second levels to the first level, the repetition is repeated. For example, if the first level is set to 25 degrees Celsius and each level is increased by 5 degrees, the first level is the lowest setting of 25 degrees Celsius, and the fifth level is the highest setting of 45 degrees Celsius.

In addition, in the temperature control mode in the fourth embodiment, each time the inductive water supply device 100 is used, the feed water temperature is gradually increased from the lowest set value (for example, 25 degrees Celsius) to avoid the last used induction.
