Abstract

The invention relates to an apparatus for hand washing and disinfection by nebulisation of an in-situ electrolysed active solution. The dispensed solution contains active chlorine optionally added with ozone or peroxides.

Claims

1. An apparatus for hand disinfection comprising a rigid body provided with:

a recess for hand insertion;

an electrochemical cell provided with a timer, suitable for producing an oxidant solution by electrolysis of an aqueous electrolytic medium during a predefined time;

a device for nebulising the oxidant solution inside the recess for hand insertion;

at least one probe suitable for detecting hand insertion inside the recess;

an actuator suitable for commanding the upload of a predefined volume of the aqueous electrolytic medium inside the electrochemical cell and the timed execution of the electrolysis;

the probe and the nebulising device being connected to an electronic control board suitable for commanding the nebulisation of the oxidant solution based on the detection of the probe.

2. The apparatus according to claim 1, wherein the actuator is connected to the electronic board and commanding the nebulisation of the oxidant solution when the actuator is consecutively triggered for a predefined number of times, independently from the detection of the probe.

4. The apparatus according to claim 1, wherein the oxidant solution contains from about 20 to about 300 ppm of active chlorine, and optional traces of ozone or peroxides.

5. The apparatus according to claim 4, wherein the predefined volume is from about 1 to about 20 ml.

6. The apparatus according to claim 4, wherein the predefined time is from 1 to about 5 seconds.

7. The apparatus according to claim 1, wherein the probe suitable for detecting hand insertion comprises a photocell.

8. The apparatus according to claim 1, wherein the aqueous electrolytic medium is an alkali chloride brine supplied to the electrochemical cell from a dispenser bottle.

9. The apparatus according to claim 1, wherein the aqueous electrolytic medium is an alkali chloride brine supplied to the electrochemical cell from a disposable cartridge.

10. The apparatus according to claim 1, further comprising an electrical power supply from grid, rechargeable batteries or solar panels, alone or in mutual combination.

3. An apparatus for hand disinfection comprising a rigid body provided with:

a recess for hand insertion;

an electrochemical cell provided with a timer, the cell suitable for producing an oxidant solution by electrolysis of an aqueous electrolytic medium during a predefined time;

a device for nebulising the oxidant solution inside the recess for hand insertion; and

at least one probe suitable for detecting hand insertion inside the recess;

the probe, the electrochemical cell and the nebulising device being connected to an electronic control board suitable for commanding the upload of a predefined volume of the aqueous electrolytic medium inside the electrochemical cell, the execution of the electrolysis and the nebulisation of the oxidant solution based on the detection of the probe.
