A front end of a steering grill from which air is discharged protrudes further than the front surface of a door assembly, and the steering grill is steered by a steering assembly, and thus conditioned air may be provided by a directed air movement to a long-distance target region, and since the front end of the steering grill protrudes further than the front surface of the door assembly, the occurrence of flow resistance as a result of a cabinet assembly or the door assembly interfering with the discharged air may be minimized, and the direction of the steering grill may be instantly changed, by means of steering, from any one direction to another among up, down, left, right, upper left, lower left, upper right, or lower right.

A single-package air conditioner appliance includes a housing defining an outdoor portion and an indoor portion; an outdoor heat exchanger assembly disposed in the outdoor portion; an indoor heat exchanger assembly disposed in the indoor portion; a compressor in fluid communication with the outdoor heat exchanger and the indoor heat exchanger; an intake conduit extending from the housing, the intake conduit defining an intake passage upstream from the indoor inlet, the intake conduit further defining a secondary inlet upstream from the intake passage to permit air thereto; a secondary air duct extending from the intake conduit outside of the housing upstream from the secondary inlet to direct air thereto, the secondary air duct defining a secondary air passage; and a damper door provided in the secondary air duct to allow air therethrough, the damper door including a spring member selectively biasing the damper door against the secondary air duct.

A door cover assembly closes a front discharge port when a fan assembly is not operated and allows the door cover assembly to move out of the front discharge port, and the front discharge port opens when the fan assembly is operated, and a fan housing assembly can protrude out of a door assembly by means of an actuator when the front discharge port is opened.

Device for dehumidifying a closed casing. The device for dehumidifying comprises a box comprising an inlet communicating with the interior of the closed casing and an outlet, a heating module able to be controlled to generate heat, a desiccant configured to adsorb moisture when it is not heated by the heating module and to return adsorbed moisture by desorption when it is heated by the heating module, a mobile plug able to be moved to alternately open and close the inlet and the outlet, a bias spring configured to move the mobile plug when the heating module does not heat the desiccant and a shape memory alloy spring configured to move the mobile plug when the heating module heats the desiccant, said shape memory alloy spring being able to be heated by the heating module at the same time as the desiccant. The device for dehumidifying is suited for dehumidifying any type of closed casing, it is cost efficient both in design and in power consumption, and it is easy to implement thanks to its small size and its simple design.

A damper assembly includes a frame, a damper blade coupled to the frame and configured to transition between an open position and a closed position, and a latch configured to be secured within the damper assembly via a clip portion of the latch. The latch is configured to deform to facilitate transitioning of the damper blade from the open position to the closed position and then to expand to capture and retain the damper blade in the closed position.

A door cover assembly closes a front discharge port when a fan assembly is not operated and allows the door cover assembly to move out of the front discharge port, and the front discharge port opens when the fan assembly is operated, and a fan housing assembly can protrude out of a door assembly by means of an actuator when the front discharge port is opened.
