Wash-hand basin and hand washing device with the wash-hand basin

Abstract

A bowl section of a wash-hand basin main body is provided with an overflow edge section of which part is extended upward to form an extension section. The extension section is provided with a cleaning fluid ejection port adapted to eject soapy water or the like for removing dirt and/or bacteria adhered to a user's hands. In this construction, the extension section continuously formed at a section of the overflow edge section of the bowl section functions as a conventional function case and as result, the number of parts and the number of execution man-hours can be reduced. Since a clearance or gap as seen in the prior art is not produced, cleaning efficiency can be improved. A cleaning fluid is filled in a tank, and a cleaning fluid refilling port for refilling the cleaning fluid from the tank is provided on the inner surface of a water receiving section. The cleaning fluid within the tank is supplied to the cleaning fluid ejection port by a pump. In this manner, it is possible to easily refill the cleaning fluid without dirtying the function case or a counter.
