Abstract

An automated hand-washing device includes a case-like housing having two openings (A), into which the user can introduce the hands for disinfection and automated spraying of an antispetic solution operating without hand contact through spray nozzles, from where the antispetic solution jet is directed precisely to the correct spot; the fingertips, the fingers and part of the palm. The openings (A) are oval, vertically elongated ellipses and they contain substantially equally shaped recesses, which urge the hands into the correct position for the period of disinfection.

Claims

1. Automated hand-washing device, consisting of a case-like housing having two openings (A), into which the user'"'"'s hands are introduced for disinfection and comprising automated spraying of antiseptic solution operating without hand contact through spray nozzles (13, 14), from which the antispetic solution jet is directed precisely to the correct spot:

the fingertips, the fingers and part of the palm, characterised in that the openings (A) are oval, vertically elongated ellipses containing substantially equally shaped recesses, which urge the hands into the correct position for the period of disinfection.

2. Automated hand-washing device as defined in claim 1, characterised in that the recesses are tapered inwardly.

3. Automated hand-washing device as defined in claim 1, characterised in that one or more nozzles (13, 14) are provided within the recess.

4. Automated hand-washing device as defined in claim 1, characterised in that the automated device comprises a pressure accumulator (16), to which antiseptic solution is pumped by a fluid pump (10), and from there onwards through a solenoid valve (15) to nozzles (13, 14).

5. Automated hand-washing device as defined in claim 1, characterised in that the pressure accumulator (16) consists of a pressure tank comprising a flexible membrane bag, the operating pressure being 4-6 bars and energy being stored in the pressure accumulator (16).

6. Automated hand-washing device as defined in claim 1, characterised in that the automated device comprises a processor for monitoring the spraying process by means of a solenoid valve (15).

7. Automated hand-washing device as defined in claim 1, characterised in that the operating voltage of the automated device is 12 V DC.

8. Automated hand-washing device as defined in claim 1, characterised in that the external parts of the automated device are replacable, such as the outer walls of the openings, the “

lugs”

, which allow for a customer-designed appearance.

9. Automated hand-washing device as defined in claim 1, characterised in that the automated device is provided with a speech synthetizer, in which user-oriented information and instructions have been recorded.

10. Automated hand-washing device as defined in claim 9, characterised in that the automated device is equipped with a motion detector, which starts instructions and/or encouragements recorded in the speech synthetizer for passers-by to approach in order to disinfect their hands.

11. Automated hand-washing device as defined in claim 1, characterised in that the automated device is equipped with a venting circuit between the pressure accumulator (16) and the fluid tank (18) for conducting any air present in the system to the fluid tank.

12. Automated hand-washing device as defined in claim 2, characterised in that the automated device comprises a pressure accumulator (16), to which antiseptic solution is pumped by a fluid pump (10), and from there onwards through a solenoid valve (15) to nozzles (13, 14).

13. Automated hand-washing device as defined in claim 3, characterised in that the automated device comprises a pressure accumulator (16), to which antiseptic solution is pumped by a fluid pump (10), and from there onwards through a solenoid valve (15) to nozzles (13, 14).
