Claim 0:
1. An air conditioner comprising:
a housing comprising an outlet;
a power supply disposed inside of the housing;
a panel attachable to or detachable from a lower side of the housing, the panel comprising an inlet to introduce air therethrough;
a first filter installable to the panel to filter the introduced air;
a second filter installable to the panel and configured to further filter the introduced air using an electrostatic force, the second filter comprising a contact portion configured to be in contact with the power supply;
a lifter configured to detach the panel from the lower side of the housing by lowering the panel from an initial position to a maintenance position, and to attach the panel to the lower side of the housing by lifting the panel from the maintenance position to the initial position; and
a guide configured to guide at least a part of the panel to move along the guide upon being in contact with the guide during the lifting of the panel so that a lifting direction of the panel is guided to be in the initial position to allow the contact portion to be in contact with the power supply,
wherein:
in response to attaching the panel to the lower side of the housing, the contact portion contacts with the power supply so that the power supply supplies power to the second filter to generate the electrostatic force to filter the introduced air;
in response to detaching the panel from the lower side of the housing, the contact portion is not in contact with the power supply so that no power is supplied to the second filter; and
in response to lowering the panel to the maintenance position by the lifter, one or more of the first filter and the second filter are accessible for maintenance.
