Abstract

An air cleaner includes: a body formed with an air suction hole defined on a side of the body, and allowing air to be introduced into the body therethrough; a metal casing into which an upper section of the body is inserted from below; a flow creation mechanism disposed inside the casing to create an air flow into and through the air cleaner; a filter disposed in the body between the air suction hole and the flow creation mechanism configured to purify air; a capacitive switch partially exposed outside the casing through a switch exposure hole defined through the casing; and a printed circuit board (PCB) disposed between one side wall of the upper section of the body and an inner wall of the casing.

First claim

The invention claimed is:

1. An air cleaner comprising:
a body formed with an air suction hole defined on a side of the body, and allowing air to be introduced into the body therethrough;
a metal casing into which an upper section of the body is inserted from below;
a flow creation mechanism disposed inside the casing to create an air flow into and through the air cleaner;
a filter disposed in the body between the air suction hole and the flow creation mechanism configured to purify air;
a capacitive switch partially exposed outside the casing through a switch exposure hole defined through the casing; and
a printed circuit board (PCB) disposed between one side wall of the upper section of the body and an inner wall of the casing,
wherein the body comprises a thickened portion formed at a lower end of the upper section of the body.

2. The air cleaner according to claim 1 , wherein the capacitive switch comprises a touch button exposed through the switch exposure hole and a conductive gasket disposed between the touch button and the PCB to electrically connect the touch button to the PCB.

3. The air cleaner according to claim 2 , wherein a surface of the touch button contacting the conductive gasket is curved inward.

4. The air cleaner according to claim 2 , wherein the touch button has a larger width than the conductive gasket.

5. The air cleaner according to claim 1 , wherein a wall portion of the casing defining the switch exposure hole is rounded on an inner side thereof.

6. The air cleaner according to claim 1 , further comprising a support fin protruding from the one side wall of the body and comprises a free end extending to contact an inner surface of the casing.

7. The air cleaner according to claim 1 , wherein the body comprises a secured portion connected to the upper section, and an upper surface of the secured portion connected to the upper section extends from both side edges of the upper surface beyond the upper section to form a stepped portion.

8. The air cleaner according to claim 7 , wherein, with the upper section inserted into the casing, a lower end of the casing contacts the stepped portion.

9. The air cleaner according to claim 1 , wherein the body includes a lower section defined below the thickened portion.

10. The air cleaner according to claim 9 , wherein the lower section of the body is configured to be exposed from the casing.

11. An air cleaner comprising:
a body formed with an air suction hole defined on a side of the body, and allowing air to be introduced into the body therethrough;
a metal casing into which an upper section of the body is inserted from below;
a flow creation mechanism disposed inside the casing to create an air flow into and through the air cleaner;
a filter disposed in the body between the air suction hole and the flow creation mechanism configured to purify air;
a capacitive switch partially exposed outside the casing through a switch exposure hole defined through the casing; and
a printed circuit board (PCB) disposed between one side wall of the upper section of the body and an inner wall of the casing,
wherein the capacitive switch comprises a touch button exposed through the switch exposure hole and a conductive gasket disposed between the touch button and the PCB to electrically connect the touch button to the PCB, and
wherein the conductive gasket comprises a cuboidal elastic foam member and a conductive tape wrapped around the cuboidal elastic foam member.

12. An air cleaner comprising:
a body formed with an air suction hole defined on a side of the body, and allowing air to be introduced into the body therethrough;
a metal casing into which an upper section of the body is inserted from below;
a flow creation mechanism disposed inside the casing to create an air flow into and through the air cleaner;
a filter disposed in the body between the air suction hole and the flow creation mechanism configured to purify air;
a capacitive switch partially exposed outside the casing through a switch exposure hole defined through the casing; and
a printed circuit board (PCB) disposed between one side wall of the upper section of the body and an inner wall of the casing,
wherein the body comprises a secured portion connected to the upper section, the secured portion comprising a rail member formed inside the secured portion.

13. The air cleaner according to claim 12 , further comprising a guide portion formed on an upper side of the rail member to receive the filter.

14. The air cleaner according to claim 13 , further comprising a UV module disposed above the filter configured to emit UV light toward the filter.

15. The air cleaner according to claim 14 , wherein the filter is a photocatalytic filter.

16. The air cleaner according to claim 12 , further comprising a cover detachably coupled to the secured portion.

17. The air cleaner according to claim 16 , wherein the cover comprises a guide bar, the guide bar being fastened to the rail member to couple the cover to the secured portion.

18. The air cleaner according to claim 16 , further comprising a light shielding member disposed inside the body adjacent to a junction between an upper end of the cover and a lower end of the casing.
