Abstract
Disclosed is a plurality of guide blades configured to guide air discharged through a discharge port, and an air conditioner having the same. The guide blade includes an eddy induction groove that is concaved from at least one surface of the guide blade, and a plurality of protrusions each protruding from an inner surface of the eddy induction groove in the form of a polypyramid, to generate eddy currents of various directions, so that the guide blade may cope with air flow of various flow speeds and wind directions.
Claims14
An air conditioner comprising:
- a housing having a discharge port disposed at a front surface of the housing;
- a fan having a plurality of fan blades to discharge air through the discharge port;
- and
- a plurality of guide blades which extend in a radial direction of the discharge port and configured to guide the air discharged from the fan and passing through the discharge port, each of the plurality of guide blades including:
- a plurality of eddy induction grooves that are concavely formed on at least one surface of a respective guide blade to generate eddy currents, and
- a plurality of protrusions, each of the plurality of protrusions formed in a pyramid shape that protrudes from inner surfaces of respective eddy induction grooves with edges of the plurality of protrusions forming a polypyramid structure.
A guide blade disposed on a downstream side of a fan having a plurality of fan blades and configured to guide air discharged from the fan, the guide blade comprising:
- a plurality of eddy induction grooves that are concaved from at least one surface of the guide blade to generate eddy currents, the guide blade formed to extend in a radial direction of a discharge port;
- and
- a plurality of protrusions, each of the plurality of protrusions formed in a pyramid shape that protrudes from inner surfaces of respective eddy induction grooves with edges of the plurality of protrusions forming a polypyramid structure.
An air conditioner comprising:
- a discharge port;
- a fan having a plurality of fan blades to discharge air through the discharge port;
- and
- a plurality of guide blades which extend in a radial direction of the discharge port and configured to guide the air discharged from the fan and passing through the discharge port, each of the plurality of guide blades including:
- a plurality of eddy induction grooves formed so that a portion of the air to be discharged is introduced into the plurality of eddy induction grooves, respectively, before the portion of the air is discharged out of the discharge port, and
- protrusions that each have a pyramid shape that protrude from inner surfaces of respective eddy induction grooves with edges of the protrusions forming a polypyramid structure to have the air introduced into the plurality of eddy induction grooves collides with the edges of the protrusions and thereby diffuses to change flow direction and thereby collide with surfaces of the protrusions,
- wherein the plurality of eddy induction grooves and the protrusions generate eddy currents in the air to be discharged through the discharge port.
