A blower may include a lower case having a suction port, a fan provided inside the lower case, an upper case provided above the lower case and having a space through which air blown from the fan flows, a discharge port penetrating the upper case and formed to be elongated, and a flow guide provided in the space and extending in a direction crossing a longitudinal direction of the discharge port.

Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

An engine including a motor and a nacelle and a duct between the nacelle and the motor. The nacelle includes a fixed structure, a mobile assembly that is mobile between an advanced position and a retracted position to define a window between the duct and the outside, and a plurality of blades that are mobile in rotation between a stowed position and a deployed position, each one extending on either side of its axis of rotation with a first arm and a second arm. In the stowed position, the first arm is outside the duct and the second arm is inside the nacelle, and where, in the deployed position, the first arm is across the duct and the second arm projects out of the nacelle. With such blades, the flow of air is optimally directed towards the front without it being necessary to provide cascades.

A blower may include a lower case having a suction port, a fan provided inside the lower case, an upper case provided above the lower case and having a space through which air blown from the fan flows, a discharge port penetrating the upper case and formed to be elongated, and a flow guide provided in the space and extending in a direction crossing a longitudinal direction of the discharge port.

A blower may include a base, a case provided above the base and having an air inlet and an air outlet, a fan provided inside the case, a rotating plate connected to the case and provided to be rotatable above the base, a motor to rotate the rotating plate, and a bearing provided between the rotating plate and the base, fixed to the rotating plate, and supported movably on the base.

There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve comprises one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further comprises a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions, and the third air outlet and the fourth air outlet each being substantially perpendicular to each of the first and second air outlets.

A diffuser arranged at the downstream side of a blower, the diffuser including a conical diffuser shroud with a back draft damping butterfly valve arranged in the diffuser opening, and where the butterfly valve includes two doors both being attached to the diffuser shroud via a hinge arrangement adapted for allowing each of the two doors to rotate between a closed and an open position about the hinge axes extending between opposite sides of the diffuser shroud and where the doors are shaped so that they together substantially close the diffuser opening when they are in their closed position, and wherein each hinge axis intersects the diffuser shroud at a position closer to the upstream side at one side than on the opposite side of the diffuser shroud.

A blower includes a first tower and a second tower spaced apart from each other each having discharge ports that face each other. A gate is movably installed in at least one of the first tower or the second tower to protrude into and out of the space between the first and second towers to change a flow of air discharged out of the discharge ports. A guide motor may be configured to move the gate. The discharge ports may be provided at a rear side of the space to discharge air toward a front of the space, while the gate may be moved to cover the front side of the space to guide air upward.

A blower may include a base, a case provided above the base and having an air inlet and an air outlet, a fan provided inside the case, a rotating plate connected to the case and provided to be rotatable above the base, a motor to rotate the rotating plate, and a bearing provided between the rotating plate and the base, fixed to the rotating plate, and supported movably on the base.

A blower includes: a fan; a lower body having an inner space to receive the fan, and a suction hole; a first upper body communicating with the inner space and having a surface with a first discharge hole; a first damper movably coupled to the first upper body and penetrating the surface; the first damper having a first end facing an outside of the first upper body and a second end opposite to the first end; and a first bar extending along and coupled to the second end of the first damper.
