A laundry treating apparatus includes a duct system including an air discharge duct for discharging air inside the drum to an outside of the drum, an air supply duct for supplying air to the drum, and a connection duct for connecting the air discharge duct and the air supply duct to each other. The apparatus also includes a heat-absorber disposed inside the connection duct to remove moisture from air, and a heat-emitter disposed inside the connection duct to heat air passing through the heat-absorber. The apparatus further includes a water ejector disposed in the duct system and defining a water flow path for supplying water to the heat-absorber to remove foreign substances remaining on the heat-absorber.

Assemblies and methods for directing a flow of air through a compressor section of a gas turbine engine are disclosed. A method includes receiving the flow of air over a strut extending radially across a substantially annular gas path of the gas turbine engine, and at least partially confining and modifying a strut wake generated in the flow of air by the strut using one or more variable orientation guide vanes.

In a refrigeration unit for use in cooling a space, such as a walk-in cold space, or other system, an easy access fan motor assembly is provided. A motor mount holds the motor with a plurality of legs that couple to a front panel using stud inserts. In some instances the legs are curved and looked like spider legs. A fan guard member covers the fan and is also attached to the stud inserts. By removing fasteners on the stud inserts, the guard member may be removed and the fan motor assembly may be removed from a position exterior to the refrigeration unit for repair or serving. Other systems and methods are disclosed.

Described is a ceiling fan having lighted blades. The ceiling fan can include a power supply supplying electrical power via a negative lead and a positive lead, and a conductive frame connected to a down rod. The ceiling fan can also include a positive voltage plate and a positive voltage plate contact that contacts the positive voltage plate while the positive voltage plate rotates. The ceiling fan can further include one or more lights disposed on a fan blade connected to the power supply.

A blower has a blower housing of clamshell construction, including two housing members having a scroll back wall molded with radial draft, an impeller and a motor within the housing, and a static tap connected to the housing. The impeller has a backplate with a backplate back surface region of substantially the same radially converging shape as that of a front surface region of the scroll back wall formed by the radial draft, providing a substantially uniform axial gap between the backplate back surface region and the scroll back wall. The impeller has a ring connected by a skirt to the back plate to define a stepped area behind the ring. The impeller includes impeller blades extending forwardly from the impeller backplate and the ring and back fins extending rearwardly from the ring. The blower has a scroll width of about twice an impeller exhaust width.

An axial flow pump comprises a housing having a bore, a cylindrical permanent magnet within the housing bore, and at least one impeller inside the permanent magnet and adapted to cause fluid to flow within the cylindrical permanent magnet. The permanent magnet is configured to rotate in the bore around its longitudinal axis. A motor lamination stack surrounds the cylindrical permanent magnet. The motor lamination stack is formed substantially as a cuboid, extending in a width and height direction perpendicular to the axis of rotation of the cylindrical permanent magnet. The diameter of the bore is at least 80% of the dimension of the cuboid in the height direction. A coil of the motor lamination is configured to be energized and to create a rotating magnetic field in the lamination stack to rotate the cylindrical permanent magnet around its longitudinal axis. The coil is disposed to one or both sides of the pump.

A fan assembly for use in a sidewall of an animal house. The fan assembly includes an impeller, a motive force configured to rotate the impeller about a fan assembly axis, and a butterfly shutter. A shutter operation mechanism moves the butterfly doors of the shutter between the closed position and the open position in synchrony with an operating speed of the impeller. The shutter operating mechanism includes pushrods connected to the butterfly doors, and a linkage between the impeller and the second pushrods. The linkage includes at least one weight configured to rotate with the impeller about the fan assembly axis, wherein rotation of the at least one weight causes the linkage to exert a force on the pushrods to push the butterfly doors toward the open position when the impeller is rotating.

A fan is disclosed. The fan includes a base mountable to a ceiling; a base motor contained in the base; a multi-section shaft operably connected to the base motor and moveable between a collapsed position and an extended position; and a fan assembly connected to the multi-section shaft and including a fan motor and at least one fan blade operably connected to the fan motor, wherein in response to a signal, the base motor raises or lowers the fan assembly by moving the multi-section shaft between the collapsed position and the extended position.

A cooling device includes a fan frame including a bottom plate and a base part disposed on the bottom plate, a stationary pillar coupled to the fan frame, and a fan assembly that is rotatably disposed about the stationary pillar. The fan assembly is supported on the stationary pillar by at least one bearing positioned between the fan assembly and the stationary pillar. The cooling device also includes a decorative plate coupled to the stationary pillar. The decorative plate has an identifying indicia that permits at least some light to pass therethrough. The cooling device further includes a light emitting assembly disposed on the fan frame and configured to emit light that is directed toward the identifying indicia.
