A blower comprising: a centrifugal fan; a driving unit for rotating the centrifugal fan; a bracket including a base fixedly-coupled to one side of the driving unit and a protrusion protruded from the base in a shaft direction of the centrifugal fan; and a fan housing fixedly-coupled to the bracket so as to rotatably receive the centrifugal fan, and including a suction port formed at one side of the bracket in the shaft direction of the centrifugal fan so as to suck air by the rotation of the centrifugal fan, and a discharge port formed in a perpendicular direction of the suction port, for discharging the air sucked through the suction port, wherein one side of the discharge port is formed in 'V' shape by a first inclination surface formed in the protrusion of the bracket and a second inclination surface formed at the fan housing which is contact with one end of the protrusion, and at least one of the first and second inclination surfaces is formed in a curved line so as to increase a discharge area of the discharge port, whereby a flow rate discharged through the discharge port can uniformly be distributed so as to reduce noise and simultaneously increase a discharged air volume.

Blower and design method of discharge port thereof

An over-the-range (OTR) microwave oven includes a main body installed above a cooking source of a gas range and has therein a cavity and an electric equipment chamber in which a magnetron is located. An air exhaust path is installed inside the main body and provides a path through which air generated from the cooking source which is introduced through a suction port formed at the bottom of the main body by a suction force of a blower installed at the main body is exhausted to the outside of the main body. An airstream guide path is installed inside the main body and provides a path through which air inside the electric equipment chamber is discharged to a front end portion of the bottom of the main body by a flow generating apparatus installed inside the electric equipment chamber in order to guide air from the cooking source to the suction port, so that delightfulness of a cooking environment is obtained by blocking air containing cooking by-products which used to flow toward the face of the cook, thereby improving product reliability and competitiveness.
