PROBLEM TO BE SOLVED: To provide an automatic washhand device which can control the feed rate of cleaning liquid by controlling a control section. SOLUTION: According to the structure of the automatic washhand device 1, a mixing nozzle 12 is an ejector using water, which functions to suck the cleaning liquid therein from a cleaning liquid tank 2, and to mix the cleaning liquid and water with each other. A cleaning liquid feeding channel 123 has a branch channel 16 connected thereto, and a depressure switch valve 161 controlled by the control section 15 is attached to a release end of the branch channel 16. Thus when the control section 15 closes the depressure switch valve 161, the cleaning liquid is sucked from the cleaning liquid tank 2 by suction force of the mixing nozzle 12, transmitted via the cleaning liquid feeding channel 123, and therefore the cleaning liquid is delivered to the mixing nozzle 12. On the other hand when the control section 15 opens the depressure switch valve 161, the suction force of the mixing nozzle 12 is released via the branch channel 16, and therefore the cleaning liquid is not sucked from the cleaning liquid tank 2.
