ABSTRACT:
An improved control for use in a hand washing and drying apparatus including a first manually operable control device for causing operation of a solenoid-operated valve causing delivery of hand washing water directly to a bowl of the device for a preselected period of time. A second manually operable control device is provided for causing operation of a forced air drying structure of the device to provide hand drying air to the bowl. The control is arranged to prevent concurrent operation of the solenoid and air moving device. The control is further arranged to prevent concurrent operation of the electric heater of the water supply and the blower motor. Still further, the control is arranged to prevent concurrent operation of the solenoid valve of the water supply and the blower motor. The control is arranged to limit usage of electrical power so that a single conventional branch circuit can provide sufficient power to operate the device. The control provides an improved short delivery of the washing water so as to effectively require a number of manipulations of the manually operable control to effect a complete hand washing operation while continuously maintaining an adequate supply of warm water for subsequent users. The device is arranged to permit substantially continuous sequential use thereof by a number of users as in a public restroom in effecting a series of hand washing and drying operations while providing the hand washing water in sufficient volume and at the desired hand washing temperature to accommodate a series of users.
