Abstract

A 4-in-1 photo-electronic air conditioning, dehumidifying, purifying and disinfecting system has an activated carbon filter in the first stage to eliminate impurities, germs and bacteria in the air drawn into the system. The bacteria and germs in the extracted air, which are capable of passing through the activated carbon filter, are then eliminated by extreme-UV light emitted by extreme-UV light tubes. The excessive moisture in the air is also removed. A negative ion generator is also used to boost the level of anions in the air. These two modes operate in the following manner: the first mode involves high-voltage cathodic output that is discharged via a carbonized fibre. The ionised air is then expelled by an air drum. The second mode eliminates bacteria, germs and mould from air as it passes extreme-UV light tubes by exposure to extreme-UV light emitted by these extreme-UV light tubes.

Claims

1. A photo-electronic air conditioning, dehumidifying, purifying and disinfecting system comprising a housing containing an air drum, an electric motor, one or more extreme-UV light tubes, one or more air-arresting units, a power supply cable, a cathodic high-voltage carbonized fibre and an activated carbon filter.

2. The system according to claim 1, wherein the housing has a generally square-column shape.

3. The system according to claim 1, wherein the housing also contains a transformer, an electrical circuit board, a function switch and indicator lights.

4. The system according to claim 1, wherein the air arresting unit has a front and a rear light shield, which prevent extreme-UV light from escaping from the housing, thus protecting the user'"'"'s eyes.

5. The system according to claim 1, wherein the one or more extreme-UV light tubes are removable and may be replaced.

6. The system according to claim 1, wherein the activated carbon filter is removable and may be replaced.

7. The system according to claim 1, wherein the housing has a hand hold for the easy carriage of the system.

8. An electrical circuit system that is capable of improving specific characteristics of the environment, specifically for use in purifying indoor air and increasing the level of anions contained in the air, wherein the electrical circuit system includes:

a negative ion generating circuit;

a circuit which enables the emission of UV light at the wavelength of 253.7 nm from an extreme-UV light tube; and

a circuit which enables air conditioning and dehumidifying.

9. The electronic circuit system according to claim 8, wherein the cathodic high-voltage output is within the range of 4.5 kV to 8.5 kV.

10. The electronic circuit system according to claim 8, wherein a rheostat used in the negative ion generating circuit has the function of regulating the output of cathodic high-voltage.

11. The electronic circuit system according to claim 8, wherein a rheostat used in the circuit to emit extreme-UV light at the wavelength of 253.7 nm from a UV light tube has the function of regulating the output current.

12. The electronic circuit according to claim 8, having first and second continuous alternating cycle modes, the first involving high-voltage cathodic output discharged via a carbonized fibre, the ionized air containing the anions then being expelled by an air drum;

the second involving the elimination of bacteria, germs and mould from air as it passes extreme-UV light tubes by exposure to extreme-UV light emitted by these extreme-UV light tubes, and in addition allowing users to choose to operate in the first mode or in the second mode separately or to choose continuous simultaneous operation or to choose operation of the two modes in an alternating cycle.
