It may consist of (13).

An inlet 20 through which air is sucked may be formed in a central portion of the lower housing 13, and a discharge port 21 through which air is discharged may be formed at a radially outer side of the inlet 20. The discharge port 21 may have a substantially circular shape when viewed in the vertical direction.

With this structure, the air conditioner 1 can suck air from the lower side, cool and heat it, and then discharge the air to the lower side again.

The lower housing 13 may have a first guide surface 14a and a second guide surface 14b forming the discharge port 21. The first guide surface 14a may be provided adjacent to the inlet 20, and the second guide surface 14b may be provided to be spaced apart from the inlet 20 than the first guide surface 14a. That is, the first guide surface 14a may be provided inside the radial direction of the discharge port 21, and the second guide surface 14b may be provided outside the radial direction of the discharge port 21. The first guide surface 14a and / or the second guide surface 14b may include a coanda curved surface that guides air discharged through the discharge port 21. The coanda curved portion may induce airflow discharged through the discharge port 21 to flow in close contact with the coanda curved portion.

The lower surface of the lower housing 13 may be coupled to the grill 15 to filter dust from the air sucked into the inlet 20.

The heat exchanger 30 may be provided inside the housing 10 and may be disposed on a flow path of air between the inlet 20 and the outlet 21. The heat exchanger 30 may include a tube (not shown) through which a refrigerant flows, and a header (not shown) connected to an external refrigerant pipe to supply or recover the refrigerant to the tube. The tube may be provided with a heat exchange fin (not shown) to enlarge the heat dissipation area.

The heat exchanger 30 may have a substantially circular shape when viewed in the vertical direction. The heat exchanger 30 may be placed in the drain tray 16 so that condensate generated in the heat exchanger 30 may be collected in the drain tray 16.

Blowing fan 40 may be provided in the radially inner side of the heat exchanger (30). The blowing fan 40 may be a centrifugal fan that sucks air in the axial direction and discharges the air in the radial direction. In addition, the blowing fan 40 may be provided at the center of rotation in the center of the axial direction so as to suck air from both sides in the axial direction. The air conditioner 1 may be provided with a blowing motor 41 for driving the blowing fan 40.

With such a configuration, the air conditioner 1 may discharge the indoor air after inhaling and cooling the air in the room, or discharge the indoor air after inhaling and heating the air in the room.

The air conditioner 1 may further include a drain pump 82 connected to the heat exchanger 30 and discharging condensate collected in the drain tray 16 and the heat exchanger pipe 81 through which the refrigerant flows. . The heat exchanger pipe 81 and the drain pump 82 may be provided on the upper portion of the bridge 80 to be described later so as not to cover the suction port. Specifically, the heat exchanger pipe 81 may be seated on the heat exchanger pipe seat 16a provided in the drain tray 16, and the drain pump 82 may be a drain pump seat 16b provided in the drain tray 16. ) Can be seated.

Referring to FIG. 2, the air conditioner 1 may further include a bridge 80 provided adjacent to the discharge port 21 and extending by a predetermined length in the circumferential direction of the discharge port 21. The bridges 80 may be spaced apart from each other by a predetermined interval along the circumferential direction, and three may be provided. The bridge 100 may be provided to connect the first guide surface 14a and the second guide surface 14b.

When the discharge port 21 is formed in a circular shape and air is discharged in all directions, a relatively high pressure is formed around the discharge port 21, and a relatively low pressure is formed around the suction port 20. In addition, since air is discharged in all directions of the discharge port 21 and forms an air curtain, air to be sucked through the suction port 20 cannot be supplied to the suction port 20. In this situation, the air discharged from the discharge port 21 is sucked through the suction port 20 again, and the re-intake air causes dew condensation inside the housing 10, and the discharged air is lost, thereby reducing the haptic performance. It became.

Bridge 80 according to an embodiment of the present invention is provided on the discharge port 21 to block the discharge port 21 by a predetermined length. Accordingly, the discharge port 21 is divided into a first section S1 through which air is discharged and a second section S2 through which air is hardly discharged by being blocked by the bridge 100. That is, the bridge 100 may form a second section S2 for supplying air to be sucked through the inlet 20. In addition, the bridge 80 may reduce the pressure difference between the low pressure around the suction port 20 and the high pressure around the discharge port 21 to allow the air to be smoothly supplied to the suction port 20.

The bridge 80 may include a pair of discharge guide surfaces 80a that are closer toward the air discharge direction to minimize the second section S2 formed by the bridge 80. The air discharged from the discharge port 21 by the discharge guide surface 101 may be spread out more widely from the discharge port 21.

In FIG. 2, the air conditioner 1 is illustrated as having three bridges 80 provided at equal intervals, that is, at an angle of 120 °, but is not limited thereto, and only one air conditioner may be provided. Four bridges may be provided at an angle of 180 degrees, or four or more bridges may be arranged to be spaced apart from each other along the circumferential direction of the discharge port 21. That is, the number of bridges and the angle at which they are arranged are not limited.

In addition, when a plurality of bridges 80 are provided, the display unit 85 may be disposed under one bridge 80 of the plurality of bridges 80. The display unit 85 may display an operating state of the air conditioner 1 to the user. Specifically, the display unit 85 displays whether the air conditioner 1 is operating, displays the direction of the discharge airflow, or indicates whether the air conditioner 1 is currently driven in the cooling mode or the heating mode. It is possible to display various information related to the air conditioner 1 without being limited thereto. In addition, although not shown, but not shown, in addition to the display unit 85, the remote control receiver (not shown), an input unit (not shown) of the air conditioner 1, and an external device may be connected to the lower side of the bridge 80. At least one of the communication unit (not shown) may be provided.

The air discharged from the discharge port 21 by the bridge 80 may be spread and discharged to cool or heat the room without re-intake into the suction port 20.

The air conditioner 1 may further include a sub-channel 101 for sucking some of the air around the discharge port 21 to control the discharge air flow. Here, controlling the discharge airflow means controlling the direction of the discharge airflow, that is, the angle of discharge of the air discharged from the discharge port 21.

The sub-channel 101 is provided around the discharge port 21 so that a part of the air around the discharge port 21 flows in, and the air introduced from the inlet port 102 is discharged into the housing 10. The outlet 103 may be connected. The sub flow path 101 may be provided along an outer surface of the upper housing 11 at an outer side of the upper housing 11. Alternatively, the sub passage 101 may be provided inside the housing 10.

The sub flow path 101 is formed on the outer side of the housing 10 in the circumferential direction and communicates with the inlet 102 and extends from the first flow path 101a to the upper surface of the housing 10. It may include a second flow path (101b). The air sucked through the inlet 102 may be discharged into the housing 10 through the outlet 103 through the first passage 101a and the second passage 101b. However, the structure of the sub channel 101 is just one example, and the sub channel 101 is sufficient to connect the inlet 102 and the outlet 103, and the structure, shape, and arrangement thereof are not limited.

The inlet 102 may be formed on the second guide surface 14b provided on the radially outer side of the outlet 21. The outlet 103 may be formed on the upper surface of the upper housing 11. Specifically, the outlet 103 may be formed on the upper side of the blowing fan 40. The outlet 103 may be formed on an upper surface of the upper housing 11 adjacent to the rotation center of the blowing fan 40. In this case, the blower fan 40 may be configured to suck air from both the lower side where the inlet 20 is provided and the upper side where the outlet 103 is provided, and discharge the air in the radial direction of the blower fan 40.

By such a configuration, some of the air around the discharge port 21 may be sucked through the inlet port 102 by the suction force of the blower fan 40, pass through the sub-channel 101, and be discharged from the outlet port 103. . As some of the air around the discharge port 21 is sucked into the sub-channel 101 through the inlet 102, the traveling direction of the air discharged from the discharge port 21 may also be changed. At this time, the suction force of the blower fan 40 may be adjusted by adjusting the rotational speed of the blower fan 40. Accordingly, the amount of air that can be sucked through the inlet 102 may be adjusted. In addition, by adjusting the amount of air that can be sucked through the inlet 102, the traveling direction of the air discharged from the discharge port 21 can also be changed step by step.

On the sub-channel 101, an opening and closing control device 104 that can adjust the opening degree of the sub-channel 101 may be provided.

Opening and closing control device 104 may be a switch that can selectively open the sub-channel 101. Opening and closing control device 104 may be a damper. Opening and closing control device 104 may be disposed adjacent to the blowing fan 40 on the sub-channel (101). The opening and closing control device 104 may selectively open the sub-channel 101 so that the air around the discharge port 21 may be selectively sucked through the inlet port 102.

Specifically, referring to Figure 4, when the opening and closing control device 104 does not open the sub-channel 101, the suction force of the blowing fan 40 is not transmitted to the inlet (102). Therefore, the air around the discharge port 21 is not sucked into the inlet 102, and the discharge air flow is formed in the A1 direction. On the other hand, when the opening and closing control device 104 opens the sub-channel 101, the suction force of the blowing fan 40 is transmitted to the inlet (102). Therefore, the air around the discharge port 21 is sucked into the inlet port 102, and the discharge air flow is formed in the A2 direction. That is, the advancing direction of the discharge airflow is changed to the outer side in the radial direction of the discharge port 21 so that the discharge airflow can spread wide.

In addition, the opening and closing control device 104 may adjust the amount of air around the discharge port 21 suctioned through the inlet 102 by adjusting the opening degree of the sub-channel 101. In addition, by adjusting the amount of air around the discharge port 21 suctioned through the inlet 102, it is possible to adjust the degree of change in the advancing direction of the air discharged from the discharge port 21.

Specifically, referring to FIG. 5, when the user inputs a command to the control unit 91 to completely open the opening and closing control device 104 through the input unit 90, the control unit 91 is configured to open and close the control device 104. The sub-channel 101 is controlled to be fully opened, whereby the air discharged from the discharge port 21 is spread as far as possible to the radially outer side of the discharge port 21. That is, the discharge airflow can be formed in the A2 direction.

On the other hand, when the user inputs a command to the control unit 91 to open only a part of the opening and closing control device 104 through the input unit 90, the control unit 91 is the opening and closing control device 104 only part of the sub-channel 101. The opening is controlled so that the air discharged from the discharge port 21 spreads less radially outward of the discharge port 21 than the A2 direction. That is, the discharge airflow can be formed in a direction between the A2 direction and the A1 direction.

It is obvious to those skilled in the art that the degree of opening and closing of the opening and closing control device 104 can be more precisely controlled to form the discharge airflow in various directions.

With this configuration, the air conditioner 1 according to the embodiment of the present invention has a blade provided in the discharge port 21, and compared to the conventional structure in which the discharge airflow is controlled by the rotation of the blade, the discharge airflow without the blade structure Can be controlled. Accordingly, since there is no interference by the blade, the discharge amount can be increased and the flow noise can be reduced.

6 is a cross-sectional view showing an air conditioner 2 according to another embodiment of the present invention. 6, an air conditioner 2 according to another embodiment of the present invention will be described. However, the same components as those of the embodiment shown in FIG. 4 may be assigned the same reference numerals, and description thereof may be omitted.

The sub channel 201 of the air conditioner 2 may be provided in the lower housing 13. Specifically, the inlet 202 may be formed on the first guide surface 14a provided in the radially inner side of the discharge port 21. The outlet 203 may be provided at the suction port 20 side so as to communicate with the suction port 20. As the outlet port 203 communicates with the inlet port 20, the suction force generated at the inlet port 20 side of the blower fan 40 is transmitted to the sub channel 201 so that the inlet port 202 is provided with air around the outlet port 21. Allow to inhale.

The sub flow path 201 is formed to connect the inlet 202 and the outlet 203. The sub flow passage 201 extends along the circumferential direction and communicates with the inlet 202, and the second flow passage 201b extending radially inward of the discharge port 21 from the first flow passage 201a. ) May be included. Accordingly, the air sucked through the inlet 202 may be discharged through the outlet 203 via the first flow path 201a and the second flow path 201b. However, the structure of the sub channel 201 is just one example, and the sub channel 201 is sufficient to connect the inlet 202 and the outlet 203, and the structure, shape, and arrangement thereof are not limited.

In addition, the sub channel 201 may extend by a predetermined length along the circumferential direction of the discharge port 21. The sub-channels 201 may be provided in plurality and spaced apart from each other along the circumferential direction of the discharge port 21.

According to this configuration, the air conditioner 2 sucks the air around the discharge port 21 through the inlet port 202 formed in the first guide surface 14a by using the suction force of the blower fan 40 to suction the air inlet 20. It may be discharged into the housing 10 through the outlet 203 formed on the side.

Specifically, when the opening and closing control device 204 does not open the sub-channel 201, the suction force of the blowing fan 40 is not transmitted to the inlet 202. Therefore, the air around the discharge port 21 is not sucked into the inlet 202, and the air discharged from the discharge port 21 is discharged in the A1 direction. On the other hand, when the opening and closing control device 204 opens the sub-channel 201, the suction force of the blowing fan 40 is transmitted to the inlet 202. Therefore, some of the air around the discharge port 21 is sucked into the sub-channel 201 through the inlet 202, and the air discharged from the discharge port 21 is discharged in the A2 direction. That is, the advancing direction of the discharge airflow is changed to the inner side in the radial direction of the discharge port 21.

In addition, as shown in the embodiment shown in Figure 4, the opening and closing control device 204 by adjusting the opening degree of the sub-channel 201, thereby adjusting the amount of air around the discharge port 21 suctioned through the inlet 202. Can be. By adjusting the amount of air around the discharge port 21 suctioned through the inlet 202, the degree of change in the advancing direction of the air discharged from the discharge port 21 can be adjusted.

Specifically, when the opening / closing control device 204 fully opens the sub passage 201, the amount of air around the discharge port 21 suctioned through the inlet 202 is maximized, so that the discharge air flow is the discharge port 21. Can be maximally gathered radially inward. That is, the discharge airflow can be formed in the A2 direction.

On the other hand, when the opening and closing control device 204 opens only a part of the sub-channel 201, the amount of air around the discharge port 21 is sucked through the inlet 202 is small, the discharge air flow is the radius of the discharge port 21 Inward direction is less gathered than the A2 direction. That is, the discharge airflow can be formed in a direction between the A1 direction and the A2 direction.

It is apparent to those skilled in the art that the degree of opening of the opening and closing control device 204 can be more precisely controlled to form the discharge airflow in various directions.

7 is a cross-sectional view showing an air conditioner 3 according to another embodiment of the present invention. 7, an air conditioner 3 according to another embodiment of the present invention will be described. However, the same reference numerals are assigned to the same components as the above-described embodiments, and descriptions thereof may be omitted.

The air conditioner 3 may control a discharge air stream by bypassing a part of the air blown by the blower fan 40 to the sub flow path 301 and then discharging it in a direction different from the air discharged from the discharge port 21. . To this end, the air conditioner 3 includes a sub-channel 301 branching from the main channel P. The sub channel 301 may be provided to branch from the main channel P before the air blown from the blower fan 40 passes through the heat exchanger 30.

The sub channel 301 may connect an inlet 302 through which a portion of the air flowing through the main channel P flows, and an outlet 303 through which the air introduced from the inlet 302 is discharged. The sub passage 301 may be formed by the intermediate housing 12 and the lower housing 13. The sub channel 301 may be provided at a radially inner side of the discharge port 21. The sub flow path 301 may include a first flow path 301a communicating with the inlet 302 and a second flow path 301b connecting the first flow path 301a and the outlet 303 and extending in the circumferential direction. Can be. Accordingly, air introduced through the inlet 302 may be discharged through the outlet 303 through the first flow path 301a and the second flow path 301b. Specifically, the air passing through the first flow path 301a is branched to the entire second flow path 301b extending along the circumferential direction and then discharged through the outlet 303. However, the structure of the sub channel 301 is just one example, and the sub channel 301 is sufficient to connect the inlet 302 and the outlet 303, and the structure, shape, and arrangement thereof are not limited.

The inlet 302 may be provided on the main flow path P between the blower fan 40 and the heat exchanger 30. Accordingly, a part of the air blown by the blowing fan 40 may be introduced into the sub channel 301 through the inlet 302. Inlet 302 may be provided in drain tray 16.

The outlet 303 may be formed on the first guide surface 14a provided inside the discharge port 21 in the radial direction. The outlet 303 discharges air in a direction different from the advancing direction of the air discharged through the discharge port 21. Specifically, the direction of the air discharged through the outlet 303 after passing through the sub channel 301 is greater than the direction of the air discharged through the discharge port 21 after passing through the main channel P. It may be formed to further face radially outward).
