Abstract

An air cleaner is provided that includes a first air cleaning module including a first fan that generates an air flow toward a first discharge outlet from a first suction inlet; a second air cleaning module including a second fan that generates an air flow toward a second discharge outlet from a second suction inlet; a divider provided between the first air cleaning module and the second air cleaning module, the divider including a dividing plate space; and a printed circuit board (PCB) device provided in the dividing plate space.

Claims

1. An air cleaner comprising:

a first air cleaning module including a first, fan that generates an air flow toward a first discharge outlet from a first suction inlet;

a second air cleaning module including a second fan that generates an air flow toward a second discharge outlet from a second suction inlet;

a divider provided between the first air cleaning module and the second air cleaning module, the divider guiding air discharge from the first discharge outlet outside of the air cleaner such that the discharged air is not introduced into the second suction inlet of the second air cleaning module and including a dividing plate space; and

a printed circuit board (PCB) device provided in the dividing plate space.

2. The air cleaner according to claim 1, wherein the dividing plate space includes a through hole through which upper and lower portions of the dividing plate extend.

3. The air cleaner according to claim 1, wherein the dividing plate includes:

a first plate having a first space; and

a second plate coupled to an upper side of the first plate, the second plate having a second space.

4. The air cleaner according to claim 3, wherein the first and second spaces are arranged to extend in an upward direction to form the dividing plate space.

5. The air cleaner according to claim 1, further, including a first air guide provided at a discharge side of the first fan to guide air flow to the first discharge outlet, wherein the first air guide includes a third space in which at least a portion of the PCB device is located.

6. The air cleaner according to claim 5, wherein the third space is formed at a center portion of the first air guide and passes therethrough in a vertical direction.

7. The air cleaner according to claim 5, farther including a first discharge guide provided at a discharge side of the first air guide, the first discharge guide having the first discharge outlet, wherein the first discharge guide includes a fourth space in which at least a portion of the PCB device is located.

8. The air cleaner according to claim 7, wherein the third and fourth space portions are aligned in the vertical direction.

9. The air cleaner according to claim 7, further including a lever support coupled to one side of the dividing plate, the lever supporting device having a fifth space that communicates with the dividing plate space.

10. The air cleaner according to claim 9, wherein the lever support includes a movement guide that supports a filter of the second air cleaning module and guides movement of the filter in a vertical direction.

11. The air cleaner according to claim 1, wherein the dividing plate allows the first air cleaning module and the second air cleaning module to be spaced apart from each other in a vertical direction.

12. The air cleaner according to claim 11, wherein the PCB device includes:

a PCB support that extends in the vertical direction; and

first and second PCBs provided at both sides of the PCB support, the first and second PCBs being arranged in a radial direction.

13. The air cleaner according to claim 12, wherein the PCB device further includes a supporting plate provided at an upper side of the PCB support, the supporting plate being supported on at least a portion of the second air cleaning module.

14. The au cleaner according to claim 13, wherein the second air cleaning module includes a filter and a lever support that supports a lower side of the filter, and wherein the supporting plate is supported by the lever support.

15. The air cleaner according to claim 14, wherein the supporting plate includes an assembling guide configured to be placed in a groove of the lever support.

16. The air cleaner according to claim 15, wherein the lever support includes:

a lever supporting main body having an annular shape; and

a supporting projection that protrudes from the lever support main body, wherein the groove is recessed downward from, an upper port-on of the supporting projection.

17. The air cleaner according to claim 13, wherein the supporting plate includes a grasping portion configured to be grasped by a user.

18. The air cleaner according to claim 1, wherein the PCB device includes:

a power supply;

a case made of a nonflammable material, the case surrounding the power supply; and

an insulating member provided between the power supply and the case.

19. The air cleaner according to claim 18, wherein the PCB device includes:

a PCB support having a first surface on which the power supply is provided; and

a main PCB provided on a second surface of the PCB support.

20. An air cleaner comprising:

a first air cleaning module including a first fan that generates an air flow toward a first discharge outlet from a first suction inlet;

a second air cleaning module including a second fan that generates an air flow toward a second discharge outlet from a second suction inlet;

a divider provided between the first air cleaning module and the second air cleaning module, the divider guiding air discharged from the first discharge outlet outside of the air cleaner such that the discharged air is not introduced into the second suction inlet of the second air cleaning module; and

a printed circuit board (PCB) device provided in an annular space formed by the divider and portions of the first and second air cleaning modules.
