The housing 10 may have a substantially circular shape when viewed in a vertical direction. The housing 10 may be composed of an upper housing 20 disposed inside the ceiling L and a lower housing 30 coupled to the lower portion of the upper housing 20.

A suction panel 100 including a suction port 110 through which air is sucked may be provided in a central portion of the lower housing 30 and a discharge port 33 through which air is sucked may be formed on a radially outer side of the suction port 110 . The discharge port 33 may have a substantially circular shape when viewed in the vertical direction.

The lower housing 30 includes a first lower housing 31 coupled to the upper housing 20 and forming a discharge port 33 and a second lower housing 32 covering the lower side of the first lower housing 31 .

As shown in FIG. 5, the first lower housing 31 may be formed in three configurations. However, this may be provided in a plurality of configurations by the ease of assembly in the process and may be formed in a single piece.

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

The filter 120 may be coupled to an upper surface of the suction panel 100 to filter dust from the air drawn into the suction port 110.

The heat exchanger 80 may have a substantially circular shape when viewed in the vertical direction.

The heat exchanger 80 is placed on the drain tray 90 so that the condensed water generated in the heat exchanger 80 can be collected in the drain tray 90.

The blowing fan 40 may be provided inside the heat exchanger 80 in the radial direction. The blowing fan 40 may be a centrifugal fan that sucks air in the axial direction and discharges the air in the radial direction. The indoor unit (1) of the air conditioner may be provided with a blowing motor (41) for driving the blowing fan (40).

Further, the airflow control device 50 can control the amount of air sucked around the discharge port 33. [ That is, the airflow control device 50 can control the direction of the discharge airflow by controlling the suction amount of the air around the discharge port 33. [

Here, controlling the direction of the discharge airflow means controlling the angle of the discharge airflow.

The airflow control device 50 can suck air from one side of the advancing direction of the discharge air stream when sucking the air around the discharge port 33. [

5, if the advancing direction of the discharge airflow when the airflow control device 50 is not in operation is the A1 direction, the airflow control device 50 is operated to suck air from one side in the direction A1 So that the advancing direction of the discharge airflow can be switched to the direction A2.

At this time, the angle to be switched according to the suction amount can be adjusted. That is, when the suction amount is made smaller, the angle is changed to a smaller angle, and when the suction amount is increased, the traveling direction can be changed to a larger angle.

The airflow control device 50 can discharge the sucked air to the side opposite to the traveling direction A1 of the discharge airflow. Thereby, the angle of the discharge airflow can be further increased, and the airflow control can be performed more smoothly.

The airflow control device (50) can suck air from the radially outer side of the discharge port (33).

And a third flow path 70c formed in a region where the airflow control fan 60 is seated.

Therefore, the air sucked through the inlet port 71 can be discharged through the outlet port 72 through the first flow path 70a, the second flow path 70b, and the third flow path 70c.

The structure of the guide passage 70 is only one example. The guide passage 70 is sufficient to connect the inlet 71 and the outlet 72, and the structure, shape, and arrangement of the guide passage 70 are not limited.

With this configuration, the indoor unit of the air conditioner according to the embodiment of the present invention can control the discharge airflow without the blade structure, as compared with the conventional structure in which the blades are provided at the discharge port and the discharge airflow is controlled by the rotation of the blades. Accordingly, since there is no interference by the blades, the discharge amount can be increased and the flow noise can be reduced.

In addition, the discharge port of the indoor unit of the conventional air conditioner has a linear shape in order to rotate the blades. However, the discharge port of the indoor unit of the air conditioner according to the embodiment of the present invention may be circular, The housing and the heat exchanger can also be provided in a circular shape so that the aesthetics can be improved by the differentiated design and the flow of the airflow is natural and the pressure loss is reduced As a result, the cooling or heating performance of the air conditioner can be improved.

Therefore, when the indoor unit 1 of the air conditioner is installed in a state where the cover member 700 according to another embodiment of the present invention shown in FIGS. 28 to 32 is exposed, the aesthetics of the indoor unit 1 of the air conditioner May be provided in an annular shape including a radius corresponding to the outer circumferential surface of the housing 10 to improve the feel.

However, the annular cover member 700 may be applied not only to the case where the cover member 700 is disposed on the ceiling in an exposed state, but also when the embedding hole in the ceiling is formed in a circular shape.

29 and 30, the cover member 700 can be pushed by the user toward the indoor unit 1 of the air conditioner and combined with the indoor unit 1 of the air conditioner. The cover member 700 can be rotated and fixed to the lower housing 30 or the drain tray 90 when the cover member 700 is pushed upward and contacts one side of the lower housing 30 or the drain tray 90 .

The coupling protrusion 710 is rotated by a user on the outer peripheral surface of the drain tray 90, An extended surface 95b disposed on the side opposite to the outer peripheral surface of the drain tray 90 (hereinafter, the extended surface is referred to as a first extended surface 95b ' ) And an extending surface 95b on the side extending outward from the drain tray 90 on both sides of the first extending surface is defined as a second extending surface 95b "), The engaging projection 710 is supported on the upper side of the first extending surface 95b 'so that the cover member 700 can be engaged.

32A, when the engaging projection 710 is not supported on the upper side of the first extending surface 95b ', the engaging projection 710 is not fixed because it can not be engaged with the drain tray 90, When the engaging projection 710 rotates along the outer peripheral surface of the drain tray 90 and is disposed on the first extending surface 95b ', the lower side of the engaging projection 710 is supported on the first extending surface 95b_ The cover member 700 can be supported by the drain tray 90.

As described above, the recess portion 96 may be provided in another configuration such as the lower housing 30 including the assembly portion, not the drain tray 90.

Since the cover member 700 is formed in an annular shape, the coupling protrusion 710 is formed to protrude inward along the outer circumferential surface so that the user can naturally rotate the cover member 700 while the coupling protrusion 710 is in contact with the first extended surface 95b ' ). ≪ / RTI > This allows the user to intuitively engage the cover member 700, thereby providing convenience, and eliminates the need for a separate additional member for coupling the cover member 700 to the indoor unit 1 of the air conditioner, thereby reducing the production cost And to reduce the process.

As shown in FIG. 31, a stopper 720 may be provided on one side of the coupling protrusion 710. As described above, the cover member 700 is rotated by the engagement protrusions 710 disposed on the first extended surface 95b 'and supported on the drain tray 90. [ Also, when the cover member 700 is detached, the user may rotate and release the coupling protrusion 710 on the first extended surface 95b 'to separate the cover member 700. [

At this time, even if the cover member 700 is not separated, the cover member 700 may be rotated when a physical force such as external pressure is applied. When the cover member 700 is rotated, The engagement of the cover member 700 may be undesirably disengaged when it is separated from the extended surface 95b '.

In order to prevent this, a stopper 720 is provided at one side of the coupling protrusion 710 to prevent the cover member 700 from being rotated arbitrarily.

The stopper 720 may extend in the vertical direction at one side of the engaging projection 710 and may protrude inward of the cover member 700. The stopper 720 may be disposed to correspond to one side of the second extending surface 95b " when the engaging projection 710 is disposed on the first extending surface 95b & Even if a rotational force is applied, the stopper 720 abuts against the second extended surface 95b "to limit the rotation of the cover member 700. [

An auxiliary coupling protrusion 730 may be provided on the lower side of the coupling protrusion 710 so as to be in contact with one side of the recess portion 96 when the coupling protrusion 710 is disposed on the first extended surface 95b '

The auxiliary coupling protrusions 730 protrude inward of the cover member 700 and may extend by a length corresponding to the thickness of the first extended surface 95b '. The auxiliary coupling protrusion 730 can be disposed in contact with the side of the recess portion 96 on the side where the stopper 720 and the second extending surface 95b "

The cover member 700 can be restricted from rotating in one direction by the stopper 720 but can not be restricted when rotated in the opposite direction so that the engaging projection 710 can be prevented from rotating by the first extending surface 95b ').

In order to prevent this, the auxiliary coupling protrusion 730 may contact one side of the recessed portion 96 to restrict rotation of the cover member 700 in the opposite direction of the stopper 720 side.

Accordingly, the user can separate the cover member 700 only by separating the cover member 700 by pressing the force enough to allow the auxiliary coupling protrusion 730 to be detached from the recess portion 96.

The auxiliary coupling protrusions 730 may protrude in a triangular shape so as to guide the triangular shape of the oblique surface to be inserted into and separated from the recessed portion 96 side.

Hereinafter, the configuration of the filter 110 will be described in detail.

FIG. 33 is a partial perspective view of a filter according to an embodiment of the present invention, FIG. 34 is a plan view of a filter according to an embodiment of the present invention, and FIG. 35 is a partially enlarged view of a filter according to an embodiment of the present invention .

As described above, the filter 120 may be provided in a circular shape. The suction panel 100 is provided in a circular shape, and in particular, the indoor unit 1 of the air conditioner is formed in a cylindrical shape and can be provided in a shape corresponding thereto.

In the conventional air conditioner, the indoor unit is provided in a rectangular parallelepiped shape, and the panel having the suction port is also provided in a rectangular shape. The filter disposed on the rectangular panel is often provided in a rectangular shape according to the shape of the panel. The suction flow path through which the air flows into the blowing fan through the suction port is mainly provided in a circular shape considering the air flow, Air was not sucked into each corner and an unnecessary space was generated in the filter.

However, the filter 120 according to an embodiment of the present invention is formed in a circular shape, and the radius of the filter 120 is provided corresponding to the radius of the suction passage of the indoor unit 1 of the air conditioner, The filter 120 can be utilized as 100%.

The filter 120 includes an outer circumferential frame 121 provided in a circular shape and a plurality of inner frames 122 extending in one direction inside the outer circumferential frame 121 and the inner frame 122, And a plurality of reinforcing ribs 123 reinforcing the rigidity.

Also, as shown in FIG. 33, a plurality of inner frames 122 may include a mesh member 124 for collecting dust in the air. The mesh member 124 may be provided in a corrugated shape including a mountain 124a and a valley 124b.

This is because the cross-sectional area of the mesh member 124 increases when a plurality of bent portions are provided in a wrinkled shape, so that a large amount of dust can be collected. The mesh member 124 may be disposed between the plurality of inner frames 122 and may be coupled to both sides of the inner frame 122.

Bending projections 122a are formed on both sides of the inner frame 122 and include the same crests of the crests 124a and the crests 124b of the mesh member 124 so that the mesh members 124 are disposed on both sides of the inner frame 122 As shown in Fig.

A plurality of reinforcing ribs 123 intersecting the inner frame 122 may be crossed on the mesh member 124. The reinforcing rib 123 may extend in a shape corresponding to the wrinkle shape of the mesh member 124 so as to cross the inner frame 122 while supporting the mesh member 124.

That is, the reinforcing rib 123 includes the bent portion 123c including the mountain 123a and the valley 123b corresponding to the corrugation shape in the shape of the mountain 124a and the valley 124b of the mesh member 124 RTI ID = 0.0 > 122 < / RTI >

The mountain 123a and the valley 123b of the bent portion 123c are formed so as to correspond to the mountain 124a and the valley 124b of the mesh member 124 so that the mesh member 124 is supported by the reinforcing ribs 123, respectively.

As shown in FIG. 34, the angle at which the inner frame 122 and the reinforcing rib 123 intersect may be between 0 and 180 degrees.

In the conventional air conditioner, since the filter is provided in the shape of a quadrangle, the inner frame and the reinforcing rib are crossed at 90 degrees in consideration of the efficiency when the air is sucked. In the filter 120 according to the embodiment of the present invention, The inner frame 122 and the reinforcing rib 123 can be crossed variously without being limited by the angle at which the inner frame 122 and the reinforcing rib 123 intersect.

The suction panel 100 includes a suction grill 101 forming an inlet 110. The angle of intersection of the inner frame 122 and the reinforcing rib 123 is freely set between 0 and 180 degrees So that the inner frame 122 and the reinforcing ribs 123 can be disposed on the position where the suction grill 101 is disposed.

As a result, the inner frame 122 and the reinforcing rib 123 are not exposed to the outside, thereby improving the aesthetics.

As described above, the inner frame 122 and the reinforcing rib 123 can be crossed at various angles. However, the mountain 123a or the valley 123b of the reinforcing rib contacting the inner frame 122 as shown in Fig. 35 And may intersect vertically with respect to the inner frame 122.

That is, the arrangement of the entire inner frame 122 and the reinforcing rib 123 may be arranged at an angle between 0 and 180 degrees, but the inner frame 122 at the portion where the inner frame 122 and the reinforcing rib 123 are in contact with each other And the reinforcing rib 123 may be provided vertically.

The reinforcing rib 123 is folded in a diagonal line so that the reinforcing rib 123 and the inner frame 122 are inclined in a direction perpendicular to the bar inner frame 122 including the plurality of bent portions 123c, Lt; / RTI >

The reason why the inner frame 122 and the reinforcing rib 123 are vertically tangent is that they are supported by the sieve inner frame 122 maintaining the overall wrinkled shape of the mesh member 124. When the inner frame 122 and one side of the reinforcing rib 123 are tangent to each other at an angle other than a vertical angle, the mesh member 124 of the corresponding section is wrinkled, so that the wrinkle shape can not be maintained in a certain section, And the coupling strength with the inner frame 122 or the reinforcing rib 123 may be reduced to cause a problem in durability.

However, according to one embodiment of the present invention, the mesh member 124 can maintain the wrinkle shape constantly in all areas contacting the inner frame 122, thereby solving the above-mentioned problem.

Although the technical idea of the present invention has been described above with reference to specific embodiments, the scope of rights of the present invention is not limited to these embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
