## Abstract

The present invention relates to a disinfection method to be used for cleaning. The invention is characterized in that hydrogen peroxide (H2O2) is drained/transferred from one or more tanks (16) by a liquid pressure created by one or more pumps or gravity, through one or more draining members (6) to one or more draining devices (5), which draining device (5) drains hydrogen peroxide to one or more onto one or more evaporation top surfaces (4ea) of an evaporation member (4e) of a warming/heating device (4), the evaporation top surface (4ea) is at an evaporation angle (4d) of 1 to 30 degrees in relation to the horizontal plane so that the end on the draining device (5) side draining end (4c) is higher than an opposite end of the draining device (5) of the warming/heating device (4), whereby hydrogen peroxide spreads by gravity on the evaporation member (4e) where the hydrogen peroxide (H2O2) turns into hydrogen peroxide gas, by means of which hydrogen peroxide gas the disinfection is performed, the evaporation member (4e) consists of one or more fibreglass braidings, the airflow area is reduced by one or more air guides (2) on the top side of the evaporation top surface (4ea) of the evaporation member (4ea) of the warming/heating device (2) towards the gas discharge end (4d) whereby the airflow rate is increased towards the gas discharge end (4d).

## Claims

### Claim 1

A disinfection method for use for cleaning, wherein hydrogen peroxide (H2O2) is drained/transferred from one or more tanks by a liquid pressure created by one or more pumps or gravity, through one or more draining members to one or more draining devices, which draining device drains hydrogen peroxide to one or more onto one or more evaporation top surfaces of an evaporation member of a warming/heating device, the evaporation top surface is at an evaporation angle of 1 to 30 degrees in relation to the horizontal plane so that the end on the draining device side, i.e. a draining end, is higher than an opposite end of the draining device of the warming/heating device, i.e. a gas discharge end, whereby hydrogen peroxide spreads by gravity on the evaporation member where the hydrogen peroxide (H2O2) turns into hydrogen peroxide gas, by means of which hydrogen peroxide gas the disinfection is performed, the evaporation member consists of one or more fibreglass braidings, the airflow area is reduced by one or more air guides on the top side of the evaporation top surface of the evaporation member of the warming/heating device towards the gas discharge end whereby the airflow rate is increased towards the gas discharge end.

### Claim 2 (depends on 1)

The disinfection method of claim 1, wherein the end on the draining device side has one or more blowers to blow air in the direction of the evaporation top surface of the evaporation member of the warming/heating device.

### Claim 3 (depends on 1)

The disinfection method of claim 1, wherein suction air is sucked by one or more blowers, whereby a vacuum is formed on the evaporation top surface, due to which vacuum hydrogen peroxide turns into hydrogen peroxide gas at a low temperature.

### Claim 4 (depends on 3)

The disinfection method of claim 3, wherein with one or more inward relief valves air is restricted from getting inside the disinfection device body, whereby as the blower is sucking air from inside the disinfection device body, a vacuum is generated inside the disinfection device body.
