Abstract
Abstract An automatic washer for cleaning objects, particularly hands, comprises a housing substantially enclosed on all sides with at least one opening for introduction of the objects to be cleaned, at least one nozzle, preferably a plurality of nozzles, for admitting at least one cleaning medium, whereby the nozzles are aligned and oriented appropriately to clean the surfaces of the object to be cleaned positioned in the interior of the housing, a control device detecting and responding to characteristics, particularly the shape, orientation, and position, of the object inserted into the interior of the housing to be cleaned, so as to activate the cleaning process when those characteristics correspond to those preset in the control device, and an operating mechanism which monitors and controls the method and timely running of the cleaning process.

Claim 1
Independent Claim
312 words
An automatic washer for the reproducible washing of hands and other articles and for preventing the contamination of a surrounding space, said washer comprising: a box-like housing defining a washing chamber sealed from said surrounding space and formed with at least one wall provided with at least one opening receiving a flexible seal through which a hand to be washed can be inserted; nozzle means including at least one nozzle orientable in said housing to train a jet of at least one cleaning medium upon an object disposed in said chamber and which can be a hand introduced through said opening; program-storage means provided with preprogrammed parameters of cleaning processes including: washing, rinsing and drying fluids constituting respective cleaning media to be discharged by said nozzle means, patterns of distribution of said cleaning media onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber, amounts of said cleaning media to be discharged by said nozzle means onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber, and duration of discharge of said cleaning media by said nozzle means onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber for cleaning and decontamination thereof; means for detecting and responding to the shape, orientation and position of an object introduced into said chamber and connected to said program-storage means for effecting washing of said object introduced into said chamber in accordance with selected ones of said parameters of cleaning media and of patterns of distribution, amounts of cleaning media and duration of discharge in accordance with the detected shape, orientation and position to ensure complete cleaning of said object introduced into said chamber; and means for signalling the completion of a program of washing in accordance with said selected ones of said parameters.
Claim 2
Dependent Claim
312 words
An automatic washer for the reproducible washing of hands and other articles and for preventing the contamination of a surrounding space, said washer comprising: a box-like housing defining a washing chamber sealed from said surrounding space and formed with at least one wall provided with at least one opening receiving a flexible seal through which a hand to be washed can be inserted; nozzle means including at least one nozzle orientable in said housing to train a jet of at least one cleaning medium upon an object disposed in said chamber and which can be a hand introduced through said opening; program-storage means provided with preprogrammed parameters of cleaning processes including: washing, rinsing and drying fluids constituting respective cleaning media to be discharged by said nozzle means, patterns of distribution of said cleaning media onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber, amounts of said cleaning media to be discharged by said nozzle means onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber, and duration of discharge of said cleaning media by said nozzle means onto and over objects of various orientations, configurations and types adapted to be disposed in said chamber for cleaning and decontamination thereof; means for detecting and responding to the shape, orientation and position of an object introduced into said chamber and connected to said program-storage means for effecting washing of said object introduced into said chamber in accordance with selected ones of said parameters of cleaning media and of patterns of distribution, amounts of cleaning media and duration of discharge in accordance with the detected shape, orientation and position to ensure complete cleaning of said object introduced into said chamber; and means for signalling the completion of a program of washing in accordance with said selected ones of said parameters.
