2. The air cleaner according to claim 1 , wherein the switch is configured to:

electrically couple the power adapter and the second input terminal when the power adapter is connected to the switch; and

electrically couple the output part to the first input terminal when the power adapter is disconnected from the switch.

3. The air cleaner according to claim 1 , wherein the second air cleaner is configured to:

receive power via the first input terminal when the second air cleaner is connected to the first air cleaner; and

receive power from the second input terminal when the second air cleaner is connected to the power adapter.

4. The air cleaner according to claim 1 , wherein the first air cleaner includes a connection case configured to at least partially cover the output part, and

the connection case is configured to press the power adapter in a direction away from the second air cleaner when the second air cleaner coupled to the power adapter is coupled to the first air cleaner.

5. The air cleaner according to claim 4 , wherein the power adapter includes a guide protrusion protruding from the connection case to be pressed.

6. The air cleaner according to claim 5 , wherein the second air cleaner includes a case inserting opening formed to correspond to the connection case and into which the connection case is inserted, and

the guide protrusion extends inside the case inserting opening.

7. The air cleaner according to claim 5 , wherein the second air cleaner includes a guide groove recessed in a bottom surface thereof to guide the guide protrusion.

8. The air cleaner according to claim 1 , further comprising a shaft disposed in the first cleaner to rotatably support the output part so that the output part is selectively exposed to outside of the first air cleaner or hidden inside of the first air cleaner.

9. The air cleaner according to claim 8 , wherein the second air cleaner includes a restriction portion formed at a portion connected to the power adapter, and

the power adapter includes a limiting protrusion coupled to the restriction portion.

10. The air cleaner according to claim 1 , wherein the second air cleaner includes an insertion portion formed on the bottom surface to correspond to the power adapter.

11. The air cleaner according to claim 1 , wherein the switch is configured to:

disconnect the first input terminal and the output part when the power adapter is engaged to the switch; and

disconnect the second input terminal and the power adapter when the power adapter is disengaged from the switch.

12. The air cleaner according to claim 1 , wherein the power adapter is arranged to interfere with the coupling of the first air cleaner and the second air cleaner when the power adapter is connected to the second air cleaner.

13. The air cleaner according to claim 1 , wherein the output part is disposed on top of the first air cleaner, and

at least one of the first input terminal and the second input terminal is disposed below the second air cleaner.

14. The air cleaner according to claim 1 , wherein the bottom surface of the power adapter is disposed in a same plane as the bottom surface of the second air cleaner when the power adapter is connected to the second air cleaner.

15. A home appliance comprising:

a first module having an output part;

a second module configured to be electrically connectable to the first module;

a power adapter attachable to or detachable from the second module, and to supply power to the second module;

a first input terminal provided in the second module and configured to be electrically connected to the output part;

a second input terminal provided in the second module and configured to be electrically connected to the power adapter; and

a switch disposed in the second module and configured to block an electrical connection between the power adapter and the second input terminal when the first module and the second module are combined,

wherein the first module is configured to separate the power adapter from the second module when the second module coupled to the power adapter is coupled to the first module.

16. The home appliance according to claim 15 , wherein the first module includes a connection case configured to cover at least one of the first input terminal and the second input terminal, and

the connection case is configured to press the power adapter in a direction away from the second module when the second module coupled to the power adapter is coupled to the first module.

17. The home appliance according to claim 15 , wherein the second module includes a restriction portion formed at a portion connected to the power adapter, and

the power adapter includes a limiting protrusion coupled to the restriction portion.

18. The home appliance according to claim 15 , wherein the power adapter is arranged to interfere with the coupling of the first module and the second module when the power adapter is connected to the second module.

19. The home appliance according to claim 15 , further comprising a shaft disposed in the first module to rotatably support the output part so that the output part is selectively exposed to outside of the first module or hidden inside of the first module.
