Abstract: A portable air purifier may include a housing having an accommodation space formed therein and including an inlet through which air is suctioned and an outlet through which air is discharged, a filter installed at an inside of the housing that faces the inlet, a fan module installed at the inside of the housing that faces the outlet, a filter case in which the filter is detachably installed and which is disposed between the filter and the fan module and configured to guide movement of air from the filter to the fan module, and a sanitizing portion mounted on the filter case and configured to irradiate sanitizing light toward the filter.

Abstract: A portable air purifier is provided. In the portable air purifier, a fan base is disposed between a fan module including a mixed flow fan and a filter, and forms a passage that connects the filter and the fan module while coupling the filter and the fan module. Accordingly, the portable air purifier can ensure improvement in air purification performance with no increase in size of the portable air purifier.

Abstract: A portable air purifier and a fan module therein are provided. The portable air purifier includes a fan module that is disposed between a discharge surface and a filter, and suctions air having passed through the filter, in an axial direction, and discharges the air in a direction between the axial direction and a radial direction.

Abstract: A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.

Abstract: A mixed flow fan module and a portable air purifier including a mixed flow fan module are provided. The mixed flow fan module may include a fan housing having an outer surface that is curved along a circumferential direction and defining an operation space, a fan rotatably disposed inside of the fan housing, and a fan base coupled to the fan housing and configured to guide air toward the fan.

Abstract: Disclosed is an invention related to a fan module, and a portable air purifier having same. The disclosed invention has a front end protrusion part provided on the rotation-directional front end of a fan blade provided on a fan, wherein the front end protrusion part protrudes forward in the rotational direction, from the rotation-directional front end of the fan blade, and at least a portion of the front end protrusion part further protrudes forward in the rotational direction than a connection point of a shroud and the rotation-directional front end of the fan blade.

Abstract: The present disclosure relates to a portable air purifier. The portable air purifier includes: a fan case having a narrow width portion at the front thereof and a wide width portion at the rear thereof, the narrow width portion including a space the radiuswise width of which is less than the radiuswise width of the wide width portion, and a fan blade protruding centrifugally further than the space formed inside the narrow width portion while being disposed at the wide width portion.

Abstract: An outdoor fan for an air-conditioner is provided to reduce unnecessary energy consumption and noise generated during an operation by reducing a side circulation flow generated when the fan rotates. The outdoor fan may include a hub shaft with a side hole, and rotary blades that convert rotary power received from the hub shaft into a pressure difference. The hub shaft may include a main plate unit perpendicular to the hub shaft and, positioned at a front side as compared to a virtual plane that includes the side hole, and the main plate unit to cover at least a portion of the hub shaft.

Abstract: An air conditioner is provided. A heat exchange unit of the air conditioner may include a blower fan that generates air flow within a housing, and a first shroud that guides the air flow generated by the blower fan to an outside of the cabinet. A second shroud may be coupled to an upstream end of the first shroud. An outer peripheral surface of a transverse section of the second shroud may be curved so as to stabilize air flow generated by the blower fan.
