Abstract
A hand washing and drying apparatus having automatic means for providing hand washing material and hand drying air. The hand washing and drying operation is effected within a space defined by a bowl. The bowl may be recessed within the apparatus to facilitate an efficient use of warm water and warm air during the hand washing and drying operation. The hand drying air outlet may be mounted to the bowl for delivering the hand drying air directly thereinto. Similarly, a means for delivering hand washing material in the form of water may be mounted directly to the bowl. The automatic controls may include manually operable portions adapted to be manipulated by the user without substantially removing his hands from the bowl space. A soap dispenser may be mounted in the device adjacent the bowl space. The bowl may be provided with an upper arm extending at a forward angle for facilitated hand washing and drying. The apparatus may be arranged to be wall-mounted, with space provided below the lower front edge of the bowl permitting use thereof as by handicapped persons in wheelchairs as well as by normal users standing in front of the bowl. In a modified form, the drying air delivery apparatus and the washing water heating apparatus may be mounted to a rear panel of the outer cabinet of the apparatus. The device is arranged to be effectively self-cleaning in a simple and sanitary manner, such as in a restroom open to the public, permitting continued sequential use by a number of persons.
