Provided are a blower, capable of suppressing noise occurring in a stator while significantly improving blowing efficiency, and an outdoor unit using the same. The present disclosure comprises: a bell mouth part spaced apart at a predetermined distance in the radial direction with respect to an outer circumferential end of a propeller fan; and a diffuser part installed on the downstream side of the bell mouth part, and having a flow path area which is enlarged from the upstream side toward the downstream side with a larger magnification rate than the magnification rate of the flow path area in the downstream end of the bell mouth part; and a stator part having a plurality of stators, wherein the stator part is arranged within the diffuser part.

Blower and outdoor unit of air conditioner comprising same

A cooking apparatus is provided. The cooking apparatus includes a body, a heating part disposed on an upper surface of the body and configured to heat an object to be heated, and an outlet part arranged on opposite sides of the heating part and configured to allow air to be discharged to an upper side of the body. The outlet part includes an outlet to which air is discharged, and a louver arranged on the outlet and configured to guide an airflow discharged from the outlet part to allow the airflow discharged from the outlet part to mix with an airflow generated by the heating part, thereby forming an ascending airflow directed from a front side to a rear side of the body.

Cooking apparatus

The present disclosure is to reduce a blowing resistance while securing a mechanical strength of a fan guard. An outdoor unitincludes a housingin which an air discharge port X is formed on an upper wall, a blowing fandisposed inside the housingto correspond to the air discharge port X, and a fan guardconfigured to cover the blowing fan, wherein the fan guardincludes a plurality of annular ribsdisposed to be spaced apart from each other in a radial direction of the blowing fan, and radial ribsconfigured to connect a plurality of the annular ribs, and wherein the radial ribsare formed such that free endsthereof are bent in the same direction in a cross section orthogonal to a stretching direction and a pair of opposing piece portionsincluding each of the free endsare in surface contact with each other.

Outdoor unit, air conditioner, fan guard, and method of manufacturing fan guard

A shoe dryer including a main body, a shoe receiver provided inside the main body and configured to receive a shoe, a blower configured to blow air toward the shoe received in the shoe receiving portion, a camera configured to obtain an image of the shoe by photographing the shoe received in the shoe receiver, and a control device configured to recognize information about the shoe from the image of the shoe obtained by the camera, and control a direction of air blown by the blower based on the information about the shoe.

Shoe dryer and control method thereof

Disclosed herein is an outdoor unit for an air conditioner including a blowing apparatus for reducing suction loss of a propeller fan generated in corners of a housing and achieving high efficiency of blowing and low noise. The blowing apparatus includes a housing including a wall in which an outlet is formed, a propeller fan positioned in the inside of the housing, the propeller fan facing the outlet, and a diffuser positioned at a discharging side of the propeller fan, and forming the outlet, wherein the diffuser includes an inclined surface inclined with respect to a rotation axis of the propeller fan, and an inclination angle of the inclined surface to the rotation axis of the propeller fan changes according to a circumferential direction of the diffuser.

Outdoor unit for air conditioner

Disclosed herein are a turbo fan, which is capable of implementing high efficiency of ventilation and reducing noise by providing a bended portion being bended in a reverse direction against a rotational direction of a wing between a leading edge and a tailing edge thereof to reattach an air separation generated at a negative pressure surface of the wing, and an air conditioner having the same. The air conditioner includes the turbo fan, wherein the turbo fan includes a main plate having a disc shape and on which a rotational shaft is mounted, a side plate provided to be separated from the main plate along an axial direction of the rotational shaft and having a ring shape in which an opening is provided at a center portion of the side plate, and a wing fixed between the main plate and the side plate and provided in plural numbers along a circumferential direction of the main plate, and wherein a bended portion, which is bended in a reverse direction against a rotational direction of the wing, is provided at the wing between a portion of a leading edge of the wing coming in contact with the side plate and a tailing edge of the wing.

Turbo fan and air conditioner having the same

Provided are a blower, capable of suppressing noise occurring in a stator while significantly improving blowing efficiency, and an outdoor unit using the same. The present invention comprises: a bell mouth part spaced apart at a predetermined distance in the radial direction with respect to an outer circumferential end of a propeller fan; and a diffuser part installed on the downstream side of the bell mouth part, and having a flow path area which is enlarged from the upstream side toward the downstream side with a larger magnification rate than the magnification rate of the flow path area in the downstream end of the bell mouth part; and a stator part having a plurality of stators, wherein the stator part is arranged within the diffuser part.

A propeller fan may strongly draw the flow toward the inner circumferential side and greatly improve the pressure efficiency by degrading the tendency of the flow near the pressure surface to be inclined toward the outer circumferential side at the trailing edge of the blade. The blade is provided with a recessed portion raised toward a suction surface at a central portion of a trailing edge of the blade in a radial direction such that the recessed portion is open at least on a pressure surface of the blade, the recessed portion extending from the trailing edge toward a leading edge of the blade, and a cross section of the recessed portion taken in a radial direction is provided with a pair of lateral portions rising at a predetermined angle with respect to the suction surface and facing each other. The span-wise width of the recessed portion between the lateral portions increases as the recessed portion extends from an upstream side to a downstream side.
