Abstract

The present disclosure is related to an air conditioner. The air conditioner according to one aspect of the present disclosure comprises a case having an inner space; a fan disposed inside the case; a frame coupled to a front portion of the case; a front plate coupled to the frame to be movable in a front-rear direction, wherein a suction port is formed between the front plate and the frame; a discharge flow path that air blown by the fan flows and that is spaced rearward from the suction port; and a discharge grille disposed downstream of the discharge flow path and comprising a guide inclined forward as the guide goes away from the discharge flow path, thereby preventing air discharged along the guide from being reintroduced.

First claim

What is claimed is:

1 . An air conditioner comprising:
a case having an inner space; a fan disposed inside the case; a frame coupled to a front portion of the case; a front plate coupled to the frame to be movable in a front-rear direction, wherein a suction port is formed between the front plate and the frame; a discharge flow path that air blown by the fan flows and that is spaced rearward from the suction port; and a discharge grille disposed downstream of the discharge flow path and comprising a guide inclined forward as the guide goes away from the discharge flow path.

2 . The air conditioner of claim 1 , wherein the guide is configured in plural and the plurality of guides are sapced apart from each other in the front-rear direction.

3 . The air conditioner of claim 1 , wherein the discharge grille is inclined with respect to the front-rear direction.

4 . The air conditioner of claim 1 , wherein the guide comprises:
a guide body positioned inward further than an outer surface of the discharge grille; and a guide end portion positioned outward further than the outer surface of the discharge grille.

5 . The air conditioner of claim 4 , wherein a length of the guide body is longer than a length of the guide end portion.

6 . The air conditioner of claim 1 , wherein the guide is inclined along an extending direction of the discharge grille, and
wherein an inclined angle of the guide ranges from 22 to 26 degrees.

7 . The air conditioner of claim 1 , wherein a length of the guide ranges from 12 mm to 15 mm.

8 . The air conditioner of claim 1 , wherein the discharge grille comprises:
a rear end portion positioned at a rear of the discharge flow path; and a rear protruding portion protruding outward of the case from the rear end portion and positioned at a rear of the discharge flow path.

9 . The air conditioner of claim 1 , wherein the discharge gille comprises:
a front end portion positioned at a front of the discharge flow path; and a front protruding portion protruding outward of the case from the front end portion and positioned at a rear of the suction port.

10 . The air conditioner of claim 1 , wherein the discharge grille comprises a front protruding portion positioned at a rear of a lateral wall of the frame.

11 . The air conditioner of claim 1 , wherein the guide comprises:
a rear guide connected to the case and positioned at a rear of the discharge flow path.

12 . The air conditioner of claim 11 , wherein the case comprises:
a first body forming a boundary of the discharge flow path and arranged along extending directions of the rear guide and the discharge flow path.

13 . The air conditioner of claim 1 , wherein the guide comprises:
a front guide connedted to the frame and positioned at a front of the discharge flow path.

14 . The air conditioner of claim 13 , wherein the frame comprises:
a second body forming a boundary of the discharge flow path and arranged along extending directions of the front guide and the discharge flow path.

15 . The air conditioner of claim 1 , wherein the frame comprises a second body forming a front boundary of the discharge flow path, and
wherein the second body comprises: a first body wall facing the discharge flow path; a second body wall bent forward from the first body wall; and a third body wall extending to be bent forward from the second body wall.

16 . The air conditioner of claim 1 , wherein the frame comprises:
a second body forming a boundary of the discharge flow path and having a groove that the guide is seated.

17 . The air conditioner of claim 1 , wherein the front plate comprises:
a front wall disposed to be movable in the front-rear direction from the frame; and a lateral wall protruding from the front wall, wherein the suction port is formed between the lateral wall and the frame.

18 . The air conditioner of claim 1 , wherein the discharge grille comprises:
a first discharge grille spaced apart from one side of the fan; and a second discharge grille spaced apart from the other side of the fan, and wherein the suction port comprises: a first suction port spaced forward from the first discharge grille; and a second suction port spaced forward from the second discharge grille.

19 . The air conditioner of claim 18 , wherein the frame comprises:
a first wall disposed between the first discharge grille and the first suction port; and a second wall disposed between the second discharge grille and the second sucion port.

20 . The air conditioner of claim 19 , wherein outer surfaces of the first wall and the second wall are positioned outside an outer end portion of the guide.
