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.

Portable air purifier

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.

Portable air purifier and fan module provided therein

A blower including a case; a fan; and a diffuser that is disposed downstream of the fan and guides air, discharged from the fan, toward discharge ports. The diffuser includes an outer wall; an inner wall spaced apart inwardly from the outer wall so that an air passage is formed therebetween; and a plurality of vanes that extends radially between the outer wall and the inner wall and divides the air passage into a plurality of unit passages. The outer wall and the inner wall are formed to have areas with different radial separation distances between the outer wall and the inner wall, such that in an area of the air passage of the diffuser in which air is discharged to a portion having a high flow resistance in the blower, the radial separation distance increases to widen the air passage, thereby compensating for asymmetry of the passage inside of the blower, allowing a uniform volume of air to reach an entire area of the discharge ports, and improving performance of the blower.

Blower

A method of manufacturing a light emitting device package and a method of manufacturing a display panel, the method of manufacturing a light emitting device package including forming a semiconductor laminate on a substrate such that the semiconductor laminate has a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer; separating the semiconductor laminate into semiconductor light emitters, separated from each other, by forming a trench having a predetermined depth in the substrate by etching through the semiconductor laminate in a direction of the first surface of the substrate; forming a molding that fills the trench and insulates the semiconductor light emitters from each other by applying a flexible insulating material to cover the semiconductor light emitters; forming grooves separated from each other by the molding and overlying to the semiconductor light emitters, respectively, by removing the substrate; and forming wavelength converters in the grooves.

Method of manufacturing light emitting device package and method of manufacturing display panel using the same

Provided are a condensed cyclic compound represented by Formula 1-1 or 1-2, an organic light-emitting device including the condensed cyclic compound, and an electronic apparatus including the organic light-emitting device:

Condensed cyclic compound, organic light-emitting device including the same, and electronic apparatus including the organic light-emitting device

A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, thereby minimizing the flow resistance inside the blower and greatly improving the economic efficiency and manufacturability of the blower.

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.

A blower may include a body or case having a suction hole through which air passes, a fan provided inside the body and causing a flow of air, and a filter provided inside the body. The filter may be positioned upstream of the fan and extend in a longitudinal direction of the body. A longitudinal axis of the filter may be shifted or displaced with respect to a longitudinal axis of the body.

Disclosed are an organic light-emitting device and an electronic apparatus including the same. The organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer located between the first electrode and the second electrode and including an emission layer, wherein the emission layer includes a host compound, a first dopant compound, and a second dopant compound, and the second dopant compound is represented by Formula 1,A-(Ar)  Formula 1wherein, in Formula 1, wherein, in Formulae 1 and 1-1, Ar, n11, M, CYto CY, Rto R, and a1 to a5 are the same as described in the specification.

Organic light-emitting device

Provided is an organic light-emitting device including an emission layer that includes a host, a sensitizer, and an emitter.

A blower is provided that includes a lower case having a suction hole through which air flows into the blower; an upper case which is disposed at an upper side of the lower case and which has a discharge port through which the air is discharged from the blower; a fan motor that provides a rotational force; and a fan disposed inside of the lower case and fixed to a motor shaft of the fan motor. The fan includes a hub having an outer surface, which extends at an incline at a first angle with respect to the motor shaft; a plurality of blades coupled to the hub; and a shroud having an inner surface which extends at an incline, with respect to the motor shaft, at a second angle that is greater than the first angle, and which faces the outer surface of the hub with respect to the plurality of blades, and thus, the air discharged from the fan may change into an ascending current.

The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.
