Description

AIR CONDITIONER

The present disclosure relates to an air conditioner, and more particularly, to an air conditioner installed in a window.

An air conditioner is a device that cools, heats, or purifies the indoor air and supplies it to the room.

The air conditioner is installed on a window, and can suck in indoor air, exchange heat with it, and supply it indoors, or suck in outdoor air, exchange heat with it, and discharge it outdoors. In the case of this window-type air conditioner, an indoor fan and an indoor heat exchanger through which indoor air flows are placed on the indoor side of the case, and an outdoor fan and an outdoor heat exchanger through which outdoor air flows are placed on the outdoor side of the case.

However, conventional window-type air conditioners had the problem that the size of the product increased and installation on windows became difficult due to the arrangement of parts for forming indoor air flow paths and outdoor air flow paths.

Korean Patent Document 10-2019-0078874 discloses an air conditioner installed on a window, but since the indoor intake port is located on the side and the discharge port is located at the front, there was a problem in that the volume of the product protruding from the window into the room increased.

In addition, Korean Patent Document 10-2019-0133477 had a problem in that the indoor intake and exhaust ports were located adjacent to each other, so air that should have been supplied to the indoors through the exhaust port was re-introduced into the intake port, lowering the efficiency of the air conditioner.

Due to the structure of the protrusion (22) and the discharge guide (70) described above, the air whose flow direction is primarily guided by the discharge guide (70) is secondarily guided by the protrusion (22), thereby preventing the phenomenon of air discharged through the discharge port (12) being re-introduced into the intake port (11).

Referring to Fig. 9, an air conditioner (1) is described.

Fig. 9 is a part of a cross-sectional view taken horizontally through the air conditioner (1). The rotation angle of the vane (20) shown in Fig. 8 may be different from the rotation angle of the vane (20) shown in Fig. 9.

The air blown by the indoor fan (34) can be discharged outside the case (10) through the discharge port (12). At this time, the flow direction of the air blown by the indoor fan (34) is defined as the discharge direction (X). The discharge direction (X) can be parallel to the forward and backward direction.

The first edge (23) and the protrusion (22) may be positioned forward of the front end (139). The first edge (23) and the protrusion (22) may guide the flow direction of air discharged outside the case (10).

The air introduced into the second guide space (75) can flow along the surface of the vane body (21) and join the air guided by the guide portion (73) on the upstream side of the protrusion (22). Air flowing along the surface (221) of the protrusion (22) can flow toward the first edge (23) by the Coanda effect. The surface (221) of the protrusion (22) can induce the Coanda effect and guide the air flowing along the surface (221) toward the first edge (23). The air reaching the first edge (23) can be supplied to the indoor space in front.

The length from the second edge (25) to the protrusion (22) can be defined as the first length (L1). The length from the protrusion (22) to the first edge (23) can be defined as the second length (L2). The first length (L1) can be greater than the second length (L2). That is, the length (L1) from the second edge (25) to the protrusion (22) can be greater than the length (L2) from the protrusion (22) to the first edge (23).

The width between the guide portion (73) and the front body (137) can be defined as the first width (W1). The width between the discharge guide (70) and the vane (20) can be defined as the second width (W2). The width at which the protrusion (22) protrudes can be defined as the third width (W3). The first width (W1) can mean the width of the first guide space (74). The second width (W2) can mean the width of the second guide space (75).

The first width (W1) may be larger than the second width (W2). That is, the gap (W1) between the guide portion (73) and the front body (137) may be larger than the gap (W2) between the discharge guide (70) and the vane (20).

The second width (W2) may be greater than the third width (W3). That is, the gap (W2) between the discharge guide (70) and the vane (20) may be greater than the height (W3) at which the protrusion (22) protrudes from the vane body (21).

Due to the relationship between the length and width described above, the Coanda effect by the vane (20) and the discharge guide (70) is maximized, and the flow direction of the air discharged through the discharge port (12) can be guided toward the front. Accordingly, the phenomenon of the air discharged through the discharge port (12) being re-introduced into the intake port (11) can be prevented.

Referring to Fig. 10, an air conditioner (1) is described.

Figure 10 is an enlarged view of the vane (20) and the discharge guide (70).

The protrusion (22) may protrude from the second guide surface (203). The block (24) may protrude from the first guide surface (202). The block (24) may have a through hole (241) through which the rotation support shaft (137b) passes.

Referring to FIGS. 12 and 13, the effect of an air conditioner (1) according to an embodiment of the present disclosure is explained.

Fig. 12 is a diagram showing the structure of an air conditioner (1) of the present disclosure having a protrusion (22) and a discharge guide (70). Fig. 13 is a contour explaining the flow of air discharged from the air conditioner (1) of Fig. 12. The description of the air conditioner (1) can be equally applied to the contents explained with reference to Figs. 1 to 11.

An air conditioner (1) equipped with a protrusion (22) and a discharge guide (70) can prevent air discharged through a discharge port (12) from being re-introduced into an intake port (11). Air flowing along a vane (20) can flow forward in an external area (P) of a case (10). That is, air guided in a flow direction by the protrusion (22) and the discharge guide (70) has a straight line in the Q direction.

Referring to FIGS. 14 and 15, the effect of an air conditioner (1') according to a comparative example of the present disclosure is explained.

Fig. 14 is a drawing showing the structure of an air conditioner (1') that is not provided with a protrusion and a discharge guide, unlike Figs. 1 to 13. Fig. 15 is a contour explaining the flow of air discharged from the air conditioner (1') of Fig. 14. The description of the air conditioner (1') can be applied identically to the description made with reference to Figs. 1 to 11, except for the description of the protrusion and the discharge guide.

In the air conditioner (1') equipped only with a flat vane (20'), air discharged through the discharge port is re-introduced into the suction port. The air flowing along the vane (20') can flow from the external area (P') of the case (10) toward the suction port. That is, the air flowing along the vane (20') flows in the Q' direction and is re-introduced into the suction port. Accordingly, the ventilation efficiency into the indoor space is lowered, and the cooling and heating performance of the air conditioner is deteriorated. In addition, since the cooled or heated air is re-introduced into the case, the heat exchange efficiency in the heat exchanger is lowered. In addition, the air conditioner (1') generates a vortex (R') due to the re-intake flow flowing in the Q' direction. The vortex (R') generated near the suction port and the discharge port generates noise in the air conditioner (1') and deteriorates the ventilation performance.
