The guide element 101 is provided to project at a predetermined height from the first guide surface 14. The guide element 101 can guide the discharged air flow towards the flow controller unit. of air 100.

[000148] The guide element 101 can be provided in a curved shape, having a predetermined curvature. When the guide element 101 is in the first position, a surface 101a thereof, facing the outlet 21, may have a convex shape, to guide the air, to be discharged from the outlet 21, in a downward direction, using the Coanda effect. . The other surface 101b, which is on the opposite side of the surface 101a of the guide element 101, may have a shape corresponding to that of the first guide surface 14, to contact the first guide surface 14.

The guide element 101, which has received the energy, moves along the first guide surface 14 in an upward direction, so that one end of the guide element 101 is away from the end of the first guide surface 14, from which the air is discharged. That is, the guide element 101 moves toward the discharge flow passage P2. In this case, the air, which passes through the outlet 21, through the discharge flow passage P2, passes through the guide element 101, is guided along the first guide surface 14 and is discharged from the outlet 21. That is , the air flow in a direction B, which is marked in FIG. 4, can be formed at output 21.

Here, the Coanda 2014a curved portion can guide the air, so that the air, to be discharged, can be discharged in a substantially vertical direction.

[000284] Furthermore, air, which is discharged through a section at outlet 2021, in which the air flow control device 2100 is not disposed, can be drawn towards the air, which passes through the control device of airflow 2100, and may be discharged in an airflow direction nearly similar to an airflow direction of the air passing through the airflow control device 2100.

[000285] On the other hand, with reference to FIG. 33, when the user tries to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioner 2001, to be along the outside in the radial direction of the outlet 2021, that is, tries to set the discharged air flow to be a broad air flow, which spreads widely from the air conditioner 2001, the second controller 2120 of the air flow control device 2100 opens a portion of the outside, along the radial direction of output 2021, through a user command. Here, the first controller 2110 closes a portion of the internal portion along the radial direction of the output 2021.

[000286] Specifically, when the second controlling axis 2122, which received power from the second axis driver 2124, rotates, the second opening and closing element 2121 rotates about 90° clockwise or counterclockwise. Accordingly, a portion of the outside of outlet 2021 is opened to allow air, which has passed through heat exchanger 2030, to pass therethrough.

[000287] The air, which has passed through the second controller 2120, which is open, is discharged towards the outside, in the radial direction of the outlet 2021, onto the second guide surface 2018. In this sense, the air conditioning apparatus 2001 can discharge air to a portion away from the air conditioning unit 2001, and gently cool or heat the entire internal space. The direction of the discharged air flow, in this case, is closer to the outside, in the radial direction of the outlet 2021, compared to the case, where the first controller 2121 is open, described above. Here, the Coanda 2018a curved portion can guide the air, so that the air, to be discharged, can be discharged in a substantially vertical direction.

[000288] Furthermore, air, which is discharged through a section at outlet 2021, in which the air flow control device 2100 is not disposed, can be drawn towards the air, which passes through the control device of air flow 2100, and may be discharged in an air flow direction almost similar to an air flow direction of the air passing through the air flow control device 2100.

[000289] In this way, according to the embodiments illustrated in FIGS. 29 to 33, a direction of the discharged air flow can be controlled according to the user's request, even when the outlet 2021 is provided in a circular shape.

Here, the guide ribs 2230 may be arranged to correspond to the sections, in which the air flow control devices 2100 are arranged.

[000297] The guide rib 2230 can guide the air, which passed through the air flow control device 2100.

[000298] Specifically, with reference to FIG. 34, when the user tries to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioner 2002, to be along the inner part, in the radial direction of the outlet 2021, that is, tries to set the discharged air flow to descend substantially vertically, the first controller 2110 of the air flow control device 2100 opens a portion of the internal part, along the radial direction of the outlet 2021, by a user command. . Here, the second controller 2120 closes a portion of the outside along the radial direction of the output 2021.

[000299] Specifically, when the first controlling axis 2112, which received power from the first axis driver 2114, rotates, the first opening and closing element 2111 rotates about 90° clockwise or counterclockwise. In this regard, a portion of the internal part of the outlet 2021 is opened, to allow the air, which has passed through the heat exchanger 2030, to pass through it.

[000300] The air, which has passed through the first controller 2110 which is open, is discharged substantially vertically by being guided along the first guide surface 2014. Here, the guide rib 2230 can prevent the air from being discharged, when being moved away from the first guide surface 2014, from the spreading towards the outside, in the radial direction of the outlet 2021. Specifically, the air, to be discharged, when being moved away from the first guide surface 2014, can be prevented from being discharged, by spreading outwards, in the radial direction of the outlet 2021, through a first surface 2231 of the guide rib 2230.

[000301] Furthermore, with reference to FIG. 35, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioning apparatus 2002, to be along the outside, in the radial direction of the outlet 2021, the second controller 2120 of the air conditioning device airflow control 2100 opens a portion of the outside, along the radial direction of the outlet 2021, upon a user command. Here, the first controller 2110 closes a portion of the internal portion along the radial direction of the output 2021.

[000302] Specifically, when the second controlling axis 2122, which received power from the second axis driver 2124, rotates, the second opening and closing element 2121 rotates about 90° clockwise or counterclockwise. Accordingly, a portion of the outside of outlet 2021 is opened to allow air, which has passed through heat exchanger 2030, to pass therethrough.

[000303] The air, which has passed through the second controller 2120, which is open, is discharged towards the outside, in the radial direction of the outlet 2021, by being guided along the second guide surface 2018. Here, the guide rib 2230 can, in a secondary way, guide the air, so that the air, to be discharged away from the second guide surface 2018, is discharged towards the outside, in the radial direction of the outlet 2021. Specifically, the air, to be discharged, when moving away from the second guide surface 2018, may be discharged, when spreading outwards in the radial direction of the outlet 2021, through a second surface 2232 of the guide rib 2230. The air, to be guided along of the second guide surface 2018, can be guided towards the outside, in the radial direction of the outlet 2021, by the curved portion Coanda 2018a.

[000304] Thus, according to the embodiment in FIGS. 34 and 35, because the air, which passed through the air flow control device 2100, is secondary guided by the guide rib 2230, the loss of a quantity of discharged air can be reduced and the cooling efficiency and heating can be increased.

[000313] However, although conductor 2330, illustrated in FIGS. 36 and 37, is illustrated as having a two-way branched shape, in the direction in which the air is discharged, embodiments are not in this respect limited, and the conductor 2330 may also be provided to have a substantially triangular shape. . That is, the conductor 2330 may be of any shape, as long as the shape is capable of guiding air passing through the air flow control device 2100, to the first guide surface 2014 and to the second guide surface 2018.

[000314] With reference to FIG. 36, when the user tries to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioner 2003, to be along the inner part in the radial direction of the outlet 2021, that is, tries to set the discharged air flow to descend substantially vertically, the first controller 2110 of the air flow control device 2100 opens a portion of the internal part, along the radial direction of the outlet 2021, upon a user command. Here, the second controller 2120 closes a portion of the outside along the radial direction of the output 2021.

[000315] Specifically, when the first controlling axis 2112, which received power from the first axis driver 2114, rotates, the first opening and closing element 2111 rotates about 90° clockwise or counterclockwise. In this regard, a portion of the internal part of the outlet 2021 is opened, to allow the air, which has passed through the heat exchanger 2030, to pass through it.

[000316] The air, which has passed through the first controller 2110, which is open, is discharged substantially vertically by being guided along the first guide surface 2014.

[000317] With reference to FIG. 37, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioning apparatus 2003, to be along the outside, in the radial direction of the outlet 2021, the second controller 2120 of the air flow control device 2100 opens a portion of the outside along the radial direction of the outlet 2021 upon a user command. Here, the first controller 2110 closes a portion of the internal portion along the radial direction of the output 2021.

[000318] Specifically, when the second controlling axis 2122, which received power from the second axis driver 2124, rotates, the second opening and closing element 2121 rotates about 90° clockwise or counterclockwise. Accordingly, a portion of the outside of outlet 2021 is opened to allow air, which has passed through heat exchanger 2030, to pass therethrough.

[000319] The air, which has passed through the second controller 2120, which is open, is discharged towards the outside, in the radial direction of the outlet 2021, by being guided along the second guide surface 2018. Here, the conductor 2330 can , secondarily, guide the air, so that the air, to be discharged, when removed from the second guide surface 2018, is discharged to the outside, in the radial direction of the outlet 2021.

[000335] Specifically, with reference to FIG. 38, when the user tries to set a direction of the flow of discharged air, which is discharged from the outlet 2021 of the air conditioning unit 2004, to be along the inner part, in the radial direction of the outlet 2021, i.e., tries to set the discharged air flow to descend substantially vertically, the first controller 2410 of the air flow control device 2400 opens a portion of the internal part, along the radial direction of the outlet 2021, by a user command. .

[000336] Specifically, the first opening and closing element 2411 slides through the first opening and closing element driver 2412, is inserted into the inner surface of the outlet 2021, and opens a portion of the inner part of the outlet 2021. In this sense, the air, which has passed through the heat exchanger 2030, can be discharged through the inner portion of the outlet 2021. Here, the second opening and closing member 2421 is taken from the outer surface of the outlet 2021 and closes the outer portion in the direction 2021 exit radial.

[000337] The Air, which has passed through the first controller 2410, which is open, descends substantially vertically, as it is guided along the first guide surface 2014. In this sense, the air conditioning device 2004 can generate a centralized air flow, which is capable of intensely cooling or heating a portion adjacent to the air conditioning unit 2004. The direction of the discharged air flow, in this case, is closer to the internal part in the radial direction of the outlet 2021 , compared to a case, in which the second controller 2420 is open, which will be described below. Here, the curved portion Coanda 2014a can guide the air, so that the air, to be discharged, can be discharged in a substantially vertical direction.

[000338] Furthermore, air, which is discharged through a section at outlet 2021, in which the air flow control device 2400 is not disposed, can be drawn towards the air passing through the air flow control device. airflow 2100, and may be discharged in an airflow direction roughly similar to an airflow direction passing through the airflow control device 2100.

[000366] With reference to FIGS. 41 and 42, when the user attempts to define a direction of the discharged air flow, which is discharged from the outlet 2021, of the air conditioning unit 2005, to be along the inner part, in the radial direction of the outlet 2021 (the first direction), the opening and closing element 2520 of the air flow control device 2500 is rotated to a position, to open the first section S1 of the guide element 2510, through a user command. In this sense, all the first sections S1 of the guide element 2510 are open, and all the second sections S2 thereof are closed by the blocker 2522. In this sense, all the air, which passed through the heat exchanger 2030, passes through the device 2500 airflow control, only through the first S1 sections.

The air, guided in the direction of the first guide surface 2014, is guided along the first guide surface 2014 and descends substantially in the vertical direction. That is, a discharged air flow direction can be adjusted to be closer to the inner part, in the radial direction of the outlet 2021, compared to a case, in which the air is guided along the second guide surface 2018 and discharged. Therefore, the air conditioning apparatus 2005 can intensively cool or heat a portion adjacent to the air conditioning apparatus 2005.

In this sense, all the second sections S2 of the guide element 2510 are opened and all its first sections S1 are closed by the blocker 2522. In this sense, all the air, which passed through the heat exchanger 2030, passes through the flow control device. airflow 2500, only through the second S2 sections.

[000369] Here, the air, which passes through the second section S2, can be guided towards the second guide surface 2018, by the second guide element 2512. The air, guided in the direction of the second guide surface 2018, is guided along the second guide surface 2018 and spreads broadly outwardly in the radial direction of the outlet 2021. That is, the air conditioner 2005 may discharge air to a portion remote from the air conditioner 2005 and, accordingly, , the 2005 air conditioning unit can gently cool or heat an entire internal space. Here, the Coanda curved portion 2018a, provided at an end portion of the second guide surface 2018, can more effectively guide the air, to be discharged from the outlet 2021, through the outlet 2021, so that the air can be discharged, spreading towards the outside, in the radial direction of exit 2021.

[000406] Here, when three or more driving devices 3150 are provided, elongated heights of three driving devices 3150 can be adjusted, and the discharge grille 3100 can be arranged to be inclined in all directions around 360° relative to a central axis of the housing 3010. Thus, the outlet 3110, provided on the discharge grille 3100, can face all radial directions of the heat exchanger 3030, or all radial directions of the discharge grille 3100.

[000407] In this sense, due to the fact that the discharged air flow, to be discharged through the outlet 3110, is formed in a direction facing the discharge grille 3100, the air can be discharged in all directions, in relation to one side surface of housing 3010.

[000408] When the actuating device 3150 does not operate, due to the fact that the discharge grille 3100 is arranged in a horizontal position, in relation to the lower housing 3012, the outlet 3110 can be arranged to face a lower side of the housing 3010, and the air discharged air, which passes through outlet 3110, can form a downward airflow and generate a centralized airflow below the air conditioning unit 3001.

[000409] However, when the driving device 3150 is elongated, the discharge grille 3100 may be obliquely disposed with respect to the lower housing 3012, the outlet 3110 may face a direction in which the discharge grille 3100 is obliquely disposed, and the discharged air flow can be formed in the direction facing the outlet 3110.

[000410] As described above, the plurality of driving devices 3150 can have different elongated lengths, that is, when the elevated and lowered lengths of the racks 3151 are changed, the vertical heights of the coupling portions 3160m corresponding thereto are changed. Thus, the discharge grille 3100 can be arranged so that the outlet 3110 can face all lateral directions, a direction in which the discharged air flow is generated can be adjusted by arranging the discharge grille 3100, and the discharged air flow can be easily controlled.

[000411] Specifically, as illustrated in FIG. 49, a first actuating device 3150a and a second actuating device 3150b, provided symmetrically along any X axis, and a third actuating device 3150c and a fourth actuating device 3150d, provided symmetrically along any Y axis, may be arranged to be spaced apart at equal intervals on the discharge grille 3100, as the plurality of actuating devices 3150.

[000412] When it is necessary that the air flow discharged in the direction of the Y axis (an E direction), in which the fourth driving device 3150d is arranged, be formed, the third driving device 3150c and the fourth driving device 3150d, arranged in direction E, can be lengthened in the vertical direction (a Z direction), so that the discharge grille 3100 faces in the E direction.

[000413] That is, a rack 3151d of the fourth driving device 3150d, disposed in direction E, can be raised by rotating a pinion 3152d, a rack 3151c of the third driving device 3150c can be lowered, by rotating a pinion 3152c, and the discharge grate 3100 can be arranged to be inclined in the direction of E.

[000414] A coupling portion 3160d, corresponding to the fourth driving device 3150d, is moved upward with respect to a Z axis, as the rack 3151d of the fourth driving device 3150d is raised, and a coupling portion 3160c, corresponding to the third drive device 3150c, is moved downward relative to the Z axis as the rack 3151c of the third drive device 3150c is lowered. In this way, the discharge grille 3100 can be arranged to be inclined by a different height between the two coupling portions 3160c and 3160d.

[000415] The pinion 3152c of the third driving device 3150c and the pinion 3152d of the fourth driving device 3150d can be rotated in opposite directions to each other, can be lowered and raised respectively, and can cause the discharge grid 3100 to be obliquely arranged.

[000416] As illustrated in FIG. 50, when it is necessary that the air flow discharged in a direction of the Y axis (an F direction), in which the third driving device 3150c is arranged, which is the opposite direction of the E direction, be formed opposite the E direction described above, the rack 3151d of the fourth driving device 3150d can be lowered by rotating the pinion 3152d, the rack 3151c of the third driving device 3150c can be raised by rotating the pinion 3152c, and the discharge grate 3100 can be arranged to be inclined in the direction of direction F .

[000417] That is, each of pinion 3152c of the third driving device 3150c and pinion 3152d of the fourth driving device 3150d, is rotated in the opposite direction of rotation, when the discharge grid 3100 is arranged in the E direction, and the discharge grid 3100 can be arranged to be inclined in the F direction.

[000418] Although not illustrated in the drawings, through this operation, the discharge grid 3100 can be arranged in the direction of the X axis, when it is necessary for the discharged air flow, in the direction of the X axis, to be formed.

[000419] Furthermore, when it is necessary for the discharged air flow to be formed in any direction G, which crosses the X axis and the Y axis (see FIG. 50), at least two actuating devices 3150b and 3150c, which are adjacent to the direction G, the coupling portions 3160b and 3160c corresponding thereto can move upward, at least two driving devices 3150a and 3150d, which are arranged on the opposite side of the direction G, can move the coupling portions 3160a and 3160d, corresponding to them, downwards, and the discharge grille 3100 can be arranged to face the G direction.

[000420] Here, the G direction can be any direction with respect to the X axis and the Y axis, instead of the direction illustrated in FIG. 50. The discharge grate 3100 can be arranged in all directions G, by the four actuating devices 3150.

[000421] As illustrated in FIGS. 51 and 53, a height, to which the driving device 3150 is raised, may vary according to a direction, in which the discharged air flow is intended to form. When it is intended to form only a portion of the discharged air flow in the F direction, only a portion of the rack 3151d of the fourth driving device 3150d can be raised and only a portion of the rack 3151c of the third driving device 3150c can be lowered, as illustrated in FIG. . 51.

[000422] In this sense, the coupling portion 3160d, corresponding to the fourth driving device 3150d, and the coupling portion 3160c, corresponding to the third driving device 3150c, can be arranged without having a large difference in height. In this regard, due to the fact that an angle, at which the discharge grille 3100 is inclined, is not large, the discharged air flow, formed in the F direction, may have a small size, and the largest portion of the discharged air flow can be formed as downward airflow.

[000423] Contrary to the above, as illustrated in FIG. 53, a difference in elongation between the third driver device 3150c and the fourth driver device 3150d can be increased, the coupling portions 3160c and 3160d can thus be arranged to have a large difference in height, an angle, at which the discharge grille 3100 is inclined, it can also be increased, and a larger amount of air can be discharged in the direction of the F direction, compared with the state illustrated in FIG. 51.

[000424] As illustrated in FIGS. 52 and 54, the discharge grille 3100 can be arranged to also be inclined in the direction of the F direction, when it is desired to form more air flow discharged in the F direction. When the outlet 3110 is arranged to be closer to the F direction, the discharged air flow, which passes through the outlet 3110, is formed in the direction facing the outlet 3110, and the discharged air flow, which is closer to the F direction, can be formed.

[000425] Furthermore, as illustrated in FIG. 55, to form the discharged air flow in the E direction, which is the opposite direction to the F direction, the discharge grille 3100 can be arranged obliquely, so that the outlet 3110 is in the E direction.

[000426] The heights, to which the actuating devices 3150a, 3150b, 3150c and 3150d are raised, can be controlled, independently of each other, by a controller (not illustrated). When the user designates a desired direction for blowing air and inputs the information into the controller (not illustrated), the controller (not illustrated) can analyze a directional value related to the information, control heights, up to which the actuating devices 3150a, 3150b, 3150c, and 3150d are elongated, controlling a direction and an inclination in which the discharge grille 3100 is arranged and, in that sense, controlling the flow of discharged air formed in the air conditioning apparatus 3001.

[000427] As illustrated in FIGS. 51 and 53, a height, to which the coupling portion 3160 can be moved, can be adjusted according to a length of the rack 3151. That is, a height, to which the rack 3151 extends vertically, can be the distance maximum that can be formed between the plurality of coupling portions 3160. In this sense, as the length of the rack 3151 is greater, an angle, at which the discharge grille 3100 can be arranged, can be greater, and more air flow discharged can be formed to the sides. In this sense, the length, in which the rack 3151 extends vertically, is not limited to the embodiment of the present disclosure, and can be defined by considering a direction of air, which must be discharged laterally by the air conditioning apparatus 3001.

[000428] Next, an actuating device, still in accordance with another embodiment of the present disclosure, will be described. Since elements, other than the driving device, which will be described below, are the same as those of the air conditioning apparatus 3001, according to the embodiment described above, their descriptions will be omitted.

[000429] Although a drive device may be provided in the form utilizing rack 3151 and pinion 3152, as in yet another embodiment of the present disclosure described above, the drive device may also be formed as a drive device 3170, including a actuator, or an actuator device 3180, including a multilink, as illustrated in FIGS. 56 and 57.

[000430] As illustrated in FIG. 56, the actuating device 3170 may include an actuator 3171 extending in a vertical direction. When the actuator 3171 is elongated in the vertical direction, a position, in which a coupling portion 3160, corresponding to the actuating device 3170, is arranged, can be moved in the vertical direction, and the discharge grille 3100 can be disposed obliquely with respect to the lower housing 3012.

[000431] One end of the actuator 3171 can be coupled to an edge of the discharge grille 3100. That is, one end of the actuator 3171 can be coupled to the coupling portion 3160 of the discharge grille 3100, and the other end of the actuator 3171 can be coupled to a coupling projection 3023, which projects towards the inside of the discharge guide 3020.

[000432] In this sense, the actuator 3171 can be supported by the coupling projection 3023, within the discharge guide 3020, and be provided to be elongated downwards. The position of the coupling portion 3160 can be adjusted according to a length, at which the actuator 3171 is elongated downwardly.

[000433] Furthermore, as illustrated in FIG. 57, the actuator device 3180 may include a multi-link 3181 extending in a vertical direction. The multi-link 3181 may have a plurality of links scissor-coupled by a hinge, and its length may be elongated in one direction. In this sense, the multi-link 3181 can be arranged in the vertical direction and elongated in the vertical direction, a position, in which a coupling portion 3160, corresponding to the driving device 3180, is arranged, can be moved in the vertical direction, and the grid discharge port 3100 may be arranged obliquely in relation to the lower housing 3012.

[000434] One end of the multi-link 3181 may be coupled to an edge of the discharge grille 3100. That is, one end of the multi-link 3181 may be coupled to the coupling portion 3160 of the discharge grille 3100, and the other end of the multi-link 3181 can be coupled to the coupling projection 3023, which projects towards the inside of the discharge guide 3020.

[000435] In this sense, the multi-link 3181 can be supported by the coupling projection 3023 within the discharge guide 3020 and be provided to be downwardly elongable. The position of the coupling portion 3160 can be adjusted according to a length, at which the multi-link 3181 is elongated downwardly.

[000436] Next, an air conditioning device 3001 will be described, still in accordance with another embodiment of the present disclosure. Due to the fact that elements, other than the element that will be described below, are the same as those of the air conditioning apparatus 3001, still according to another embodiment described above, descriptions thereof will be omitted.

[000437] FIG. 58 is a cross-sectional side view of an air conditioning apparatus, in a state in which a discharge grille is moved downwardly by a driving device of the air conditioning apparatus, in accordance with yet another embodiment of the present disclosure, the FIG. 59 is a perspective view of the air conditioning apparatus illustrated in FIG. 58, FIG. 60 is a cross-sectional side view of an air conditioning apparatus in a state, in which a discharge grille is moved downwardly by a driving device of the air conditioning apparatus, in accordance with yet another embodiment of the present disclosure, and FIG. 61 is a perspective view of the air conditioning apparatus illustrated in FIG. 60.

[000438] As illustrated in FIG. 58, an inlet 3050', through which air is drawn in, may be arranged in the central portion of the lower housing 3012. The discharge flow passage, provided for the air drawn in through the inlet 3050' to exchange heat in the heat exchanger 3030 and be discharged, is formed on an external side, in a radial direction of the inlet 3050', and on the external side, in the radial direction of the heat exchanger 3030. Furthermore, an opening 3060, through which air, flowing along of the discharge flow passage, is discharged to the outer side of the housing 3010, may be supplied on the outer side, in the radial direction of the heat exchanger 3030 in the lower housing 3012.

[000439] The discharge flow passage can be provided in a ring shape, by the heat exchanger 3030, provided in a ring shape, and by the housing 3010, provided in a cylindrical shape. One side of the discharge flow passage 3050 may be connected to the heat exchanger 3030, and the other side thereof may be connected to the opening 3050 provided near the lower housing 3012.

[000440] Through the above structure, the air conditioning apparatus 3001' can draw in air from a lower side, cool and heat the air, and then discharge the air back to the lower side.

[000441] A blow fan 3040' may be provided on the internal side, in the radial direction of the heat exchanger 3030. The blow fan 3040' may be a centrifugal fan configured to draw in air in an axial direction and discharge air in a radial direction . A fan motor 3041', configured to drive the blower fan 3040', may be provided in the air conditioning apparatus 3001'.

[000442] A discharge grille 3200 can be arranged in the opening 3060 of the discharge flow passage. The discharge grille 3200 may include a plurality of outlets 3210, through which air, to be discharged to the outside of the housing 3010, passes the blower fan 3040'.

[000443] Although the discharge grille 3200 may preferably be provided in the form of a ring-shaped plate, the embodiments are not, in this respect, limited, and the discharge grille 3200 may be provided in the shaped like a polygonal plate. Specifically, the discharge grille 3200 may have a shape corresponding to that of the discharge flow passage opening 3060. That is, when the opening 3060 is formed into a polygonal shape, the discharge grille 3200 can be formed into a polygonal ring shape corresponding to the shape of the opening 3060.

[000444] A driver device 3250 can be arranged on an edge of the discharge grille 3200. Specifically, a plurality of driver devices 3250 can be provided. The number of actuator devices 3250 according to the present disclosure may be four. However, the number of actuating devices 3150 is not limited to the embodiment of the present disclosure, and may be other numbers.

[000445] The plurality of actuating devices 3250 can be arranged by being coupled to the edge of the discharge grille 3200, that is, an outer circumferential surface of the discharge grille 3200, and spaced apart from each other. Preferably, the actuating devices 3250 may be arranged to be symmetrically spaced apart from each other with respect to the discharge grille 3200.

[000446] At least two driver devices 3250, among the plurality of driver devices 3250, can be elongated to different lengths, relative to the vertical direction of the housing 3010, as in the embodiment described above. Thus, the discharge grille 3200 can be arranged obliquely with respect to the lower housing 3012, and the flow of discharged air can be controlled.

[000447] When the plurality of actuating devices 3250 operates, as illustrated in FIG. 59, one side of the discharge grille 3200, provided in a ring form, can be lowered to the lower side of the lower housing 3012, the other side of the discharge grille 3200 can be raised to the upper side of the lower housing 3012, and the discharge grate 3200 can be arranged obliquely.

[000448] As illustrated in FIGS. 60 and 61, ring-shaped discharge grates 3200 can be supplied separately. According to yet another embodiment of the present disclosure, two discharge grilles 3200a and 3200b may be formed separately. However, the embodiments are not limited in this respect, and three or more discharge grilles can be formed separately.

[000449] When the plurality of discharge grilles 3200a and 3200b are provided, a plurality of driving devices 3250a and 3250b corresponding thereto can be provided, and the plurality of driving devices 3250a and 3250b can be controlled independently.

[000450] Therefore, although the discharge grille 3200, described above, can be disposed towards one side, by the driving device 3250, and form flow of discharged air to one side, the plurality of discharge grilles 3200a and 3200b can be arranged in different directions, independently of each other and thus form air flow discharged in a plurality of directions.

[000451] Next, an air conditioning apparatus 3001'', still in accordance with another embodiment of the present disclosure, will be described. Due to the fact that elements, other than the elements that will be described below, are the same as those of the air conditioning apparatus 3001, still according to another embodiment described above, their descriptions will be omitted.

[000452] FIG. 62 is a perspective view of an air conditioning apparatus, in accordance with yet another embodiment of the present disclosure.

[000453] A plurality of blowing fans 3040a, 3040b and 3040c can be formed within the housing 3010 of the air conditioning apparatus 3001'', still in accordance with another embodiment of the present disclosure. Once the plurality of blow fans 3040a, 3040b and 3040c are formed, fan motors (not shown) and discharge guides (not shown), arranged adjacent the blow fans 3040a, 3040b and 3040c, can be provided to correspond to the number of blowing fans 3040a, 3040b and 3040c.

[000454] Openings, provided to allow air, flowing through the blow fans 3040a, 3040b and 3040c, to be discharged to the outside of the housing 3010, may be provided in the lower housing 3012, to correspond to the number of blow fans. blow 3040a, 3040b and 3040c. Accordingly, three openings may be formed in the lower housing 3012, in accordance with yet another embodiment of the present disclosure.

[000455] Discharge grilles 3100a, 3100b and 3100c, with dimensions corresponding to the openings, can be provided in the three openings. The discharge grilles 3100a, 3100b and 3100c may be arranged obliquely with respect to the lower housing 3012, by a plurality of actuating devices (not shown) disposed at the edges of the discharge grilles 3100a, 3100b and 3100c, and control the flow of discharged air. .

[000456] Each of the discharge grilles 3100a, 3100b and 3100c can be independently controlled by the plurality of actuating devices (not illustrated) and independently control the flow of discharged air. Therefore, the plurality of discharge grilles 3100a, 3100b and 3100c can be independently arranged in different directions and form a flow of discharged air, which is formed in a plurality of directions.

[000457] The blowing fans 3040a, 3040b and 3040c can be provided to be coupled respectively to the discharge grilles 3100a, 3100b and 3100c, arranged below the blowing fans 3040a, 3040b and 3040c. Here, fan motors (not shown) and discharge guides (not shown) intended to be adjacent to blowing fans 3040a, 3040b and 3040c can also be provided to be coupled to blowing fans 3040a, 3040b and 3040c. in addition to blow fans 3040a, 3040b and 3040c and discharge grilles 3100a, 3100b and 3100c. Therefore, when the discharge grilles 3100a, 3100b and 3100c are moved by the driving devices (not shown), the blower fans 3040a, 3040b and 3040c, the fan motors and the discharge guides can be moved because they are interconnected. in a joint form.

[000458] That is, when the discharge grilles 3100a, 3100b and 3100c are arranged obliquely in a predetermined direction by the drive devices (not illustrated), the blowing fans 3040a, 3040b and 3040c can be arranged obliquely, by being interconnected to the discharge grilles. discharge 3100a, 3100b and 3100c.

[000459] In this sense, by means of rotating axes of the blowing fans 3040a, 3040b and 3040c, arranged to correspond to the sides, on which the discharge grilles 3100a, 3100b and 3100c are arranged, the blowing fans 3040a, 3040b , and 3040c can blow air in the direction in which the discharge grilles 3100a, 3100b and 3100c are arranged. In other words, the air blowing directions of the blower fans 3040a, 3040b and 3040c can be controlled by the driving devices (not illustrated) and the discharged air flow generated can thus be directly controlled.

[000460] Next, an air conditioning apparatus 3001a, still in accordance with another embodiment of the present disclosure, will be described. Due to the fact that the elements, other than the elements that will be described below, are the same as those of the air conditioning apparatus 3001, still according to another embodiment described above, their descriptions will be omitted.

[000461] FIG. 63 is a cross-sectional side view of an air conditioning apparatus, in accordance with yet another embodiment of the present disclosure, FIGS. 64 to 66 are views illustrating a state in which a shape of an air conditioning apparatus discharge grille is changed, in accordance with yet another embodiment of the present disclosure, FIG. 67 is a rear view of the air conditioning apparatus, still in accordance with another embodiment of the present disclosure; and FIG. 68 is a view illustrating a state, in which a blade shape of the discharge grille of the air conditioning apparatus illustrated in FIG. 67 is changed.

[000462] As illustrated in FIG. 63, a discharge grille 3300, including an outlet 3350, provided for having air blown by the blower fan 3040 pass through it to be discharged to the outside of the housing 3010, may be disposed in the opening 3021 of the discharge guide 3020. .

[000463] The discharge grille 3300 can be coupled to the opening 3021, so that the air, which flows along the discharge guide 3020, passes through the discharge grille 3300 and is discharged to the outside of the housing 3010.

[000464] The discharge grille 3300 can preferably be provided in the shape of a circular plate, but the shape is not, in this aspect, limited, and can also be provided in the shape of a polygonal plate. The discharge grille 3300 may be provided in a shape corresponding to that of the opening 3021. Thus, when the opening 3021 is formed in a polygonal shape, the discharge grille 3300 may be provided in a polygonal shape corresponding to that of the opening 3021.

[000465] The discharge grate 3300 may include a hub 3310, provided in a central portion of the discharge grate 3300, a ring-shaped structure 3330, disposed on an external side, in a radial direction of the hub 3310, and a plurality of blades 3320, disposed between hub 3310 and frame 3330 and configured to form outlet 3350.

[000466] The hub 3310 can be arranged in the central portion of the discharge grille 3300, as described above, and can be provided rotatably. A driving device 3311 configured to transmit a rotational force to cause the hub 3310 to rotate in one direction or the other may be provided above the hub 3310.

[000467] As illustrated in FIGS. 64 to 66, the plurality of blades 3320 may be disposed between the hub 3310 and the frame 3330. The outlet 3350, through which air is discharged, may be formed between the plurality of blades 3320.

[000468] Because the plurality of blades 3320 may include a soft material, the shape of the plurality of blades 3320 may be changed by interlocking with the hub 3310 when the hub 3310 is rotated.

[000469] The plurality of blades 3320 may each include a first contact portion 3321, provided at one end of the blade 3320 and coupled to the hub 3310, and a second contact portion 3322, provided at the other end of the blade 3320 and coupled to structure 3330.

[000470] Here, the second contact portion 3322 is always arranged in the same position, as it is coupled to the structure 3330. However, the first contact portion 3321 may have a changed position, as it is linked to the rotation of the hub 3310.

[000471] That is, the shape of the blade 3320 can be deformed according to a direction, in which the first contact portion 3321 is rotated, by being interconnected with the rotation of the hub 3310. When the hub 3310 is rotated clockwise , the first contact portion 3321 may also be rotated clockwise, as illustrated in FIG. 64.

[000472] As the first contact portion 3321 is rotated clockwise, due to the clockwise rotation of the hub 3310, a section, in which the first contact portion 3321 and the second contact portion 3322 are arranged, in radial direction of hub 3310, may be formed, as illustrated in FIG. 65.

[000473] Then, as illustrated in FIG. 66, as the hub 3310 continues to be rotated, the first contact portion 3321 may also be rotated clockwise, from the state that it is disposed in the radial direction with the second contact portion 3322, and may be disposed in the clockwise, after the second contact portion 3322. Here, because the first contact portion 3321 is rotated clockwise, by crossing a position, in which the second contact portion 3322 is disposed, the blade 3320 may be deformed, in a format with a direction that leads clockwise.

[000474] That is, the blade 3320 may have a clockwise deformed shape, in which the blade 3320 is rotated. In this sense, the outlet 3350, formed between the plurality of blades 3320, can also be formed in a clockwise direction.

[000475] Alternatively, although not illustrated in the drawings, when the hub 3310 is rotated counterclockwise, the blade 3320 may be rotated counterclockwise and have an inverted shape, in a direction opposite to the clockwise direction.

[000476] As described above, because the blade 3320 may include a soft material, the shape of the blade 3320 may be formed by rotating the first contact portion 3321 along a direction, in which the first contact portion 3321 is rotated. When the rotation of the first contact portion 3321 ends, a shape of the blade 3320, formed at a position, to which the first contact portion 3321 is rotated, may remain unchanged.

[000477] The blow fan 3040 may include an axial flow fan or a mixed flow fan for central discharge. In this sense, the air introduced into the blowing fan 3040 may include a rotational force, formed along a rotating direction of the blowing fan 3040, and be discharged to the outside of the housing 3010.

[000478] The air, with the force of rotation, is discharged, passing through the discharge grille 3300. When a direction, in which the shape of the blade 3320 is formed, corresponds to a direction, in which the air is rotated, the Air, which has rotational force, can pass through the discharge grille 330, while maintaining its direction without great restriction. Here, because the air, which passes through the discharge grille 3300, maintains its direction, the centralized air flow can be formed below the housing 3010, towards which the discharge grille 3300 is directed.

[000479] When a direction, in which a blade 3320a, illustrated in FIG. 67, is assumed to be identical to a rotation direction of the blowing fan 3040, an air direction may be unchanged, and the discharged air flow may be formed as centralized air flow formed below the housing 3010, even after the air have passed through a 3350a output.

[000480] On the other hand, when a direction, in which the blade 3320 is formed, is a direction opposite to that in which the air is rotated, the air, having a rotational force, may lose its direction, due to the fact that a direction, in which the air is rotated when passing through the discharge grille 3300, does not coincide with the direction, in which the blade 3320 is formed. In this sense, the air, which passes through the discharge grille 3300 with the blade 3320 formed in a direction opposite to that in which the air is rotated, may not form a centralized airflow, may lose its direction and form a broad airflow. , which spreads in all directions.

[000481] When a direction, in which a blade 3320b, illustrated in FIG. 68, is formed, is assumed to be in a direction opposite to the direction of rotation of the blowing fan 3040, the air, which passed through an outlet 3350b, may lose its direction, the centralized air flow may not be generated below, a Air direction can be changed by the 3320b blade and the air can go in all directions.

[000482] In this sense, a broad air flow can be generated when a direction, in which the blade 3320b is formed, is opposite to the rotation direction of the blowing fan 3040.

[000483] Next, an air conditioning apparatus 3001b, still in accordance with an embodiment of the present disclosure, will be described. Due to the fact that elements, other than the elements that will be described below, are the same as those of the air conditioning apparatus 3001a, still according to another embodiment described above, their descriptions will be omitted.

[000484] The discharge grille 3300 can also be applied to the air conditioning unit 3001b formed by a common quadrilateral housing, still according to another embodiment of the present disclosure.

[000485] The air conditioning apparatus 3001b, still in accordance with another embodiment of the present disclosure, may have a heat exchanger (not illustrated), provided in a quadrilateral shape, disposed within an upper housing 3011b, and, therefore, because of the quadrilateral heat exchanger, having inlets 3050b formed in a four-way shape, to be adjacent to the heat exchanger (not illustrated).

[000486] The air, drawn in through the four inlets 3050b, can pass through the discharge grille 3300, through the heat exchanger (not illustrated) and the blower fan 3040, and be discharged on the outside of the housing. Here, the shape of the blade 3320 is changed, due to the rotation of the hub 3310 in the discharge grille 3300, and as the shape of the blade 3320 is changed, the discharged air stream, to be discharged through the outlet 3350, can be easily controlled.

[000487] FIG. 70 is a perspective view of an air conditioning apparatus 4001, in accordance with yet another embodiment of the present disclosure. FIG. 71 is a cross-sectional side view of the air conditioning apparatus 4001 illustrated in FIG. 70.

[000496] The heat exchanger 4030 may be provided within the housing 4010 and may be arranged in an air flow passage, between the inlet 4020 and the outlet 4056. The heat exchanger 4030 may be formed by a tube (not illustrated) , having flow of refrigerant gas therethrough, and a head (not illustrated), connected to an external refrigerant gas tube, for supplying or collecting refrigerant gas in the tube. A heat exchange fin can be provided on the tube to expand a heat dissipation area.

[000497] Heat exchanger 4030 may have a substantially circular shape when viewed in a vertical direction. The shape of the heat exchanger 4030 may correspond to the shape of the housing 4010. The shape of the heat exchanger 4030 may correspond to the shape of the outlet 4056. The heat exchanger 4030 may be placed in a drain pan 4016, and the condensate generated in the heat exchanger 4030, can be collected in drain pan 4016.

[000498] The blow fan 4040 may be provided inside, in a radial direction of the heat exchanger 4030. The blow fan 4040 may be a centrifugal fan, configured to draw in air in an axial direction, and discharge air in a radial direction. A fan motor 4041, configured to drive the blower fan 4040, may be provided in the air conditioning apparatus 4001.

[000501] Next, the air flow control elevator unit 4100 and an air flow control element 4200 will be described in detail.

[000502] FIG. 72 is an enlarged view of a portion marked in FIG. 71, FIG. 73 is an enlarged view of a portion corresponding to that marked in FIG. 71, when an air flow control lifting unit of the air conditioning unit is raised, still in accordance with another embodiment of the present disclosure, FIG. 74 is a perspective view when the air flow control lifting unit of the air conditioning unit is lowered, still in accordance with another embodiment of the present disclosure, and FIG. 75 is a perspective view, when the air flow control lifting unit of the air conditioning unit is raised, still in accordance with another embodiment of the present disclosure.

[000503] As illustrated in FIGS. 71 and 72, the air flow control lift unit 4100 may be disposed on a central side of the lower housing 4012. The air flow control lift unit 4100 may be provided in a substantially cylindrical shape.

[000504] An outer circumferential surface 4110 of the air flow control lift unit 4100 may form one side of the discharge flow passage 4050, and an inner circumferential surface 4120 of the lift unit 4100 may form a suction flow passage 4021, configured to connect inlet 4020 to blower fan 4040 to allow air, drawn through inlet 4020, to be introduced into blower fan 4040.

[000505] The air flow control lift unit 4100 can be arranged below the drain tray 4016 and can be provided to be suspended below the drain tray 4016.

[000506] The air flow control elevator unit 4100 may include a lifting guide 4130, which extends upwardly. When the air flow control elevator unit 4100 is being raised, the lifting guide 4130 can guide the air flow control elevator unit 4100 so that the air flow control elevator unit 4100 moves up or down.

[000507] Specifically, the drain tray 416 may include a guide groove 4016a, provided to correspond to the lifting guide 4130, and the elevation of the air flow control lifting unit 4100 may be guided by the lifting guide 4130, which slides vertically in the guide groove 4016a.

[000508] As illustrated in FIG. 72, when the air flow control lifting unit 4100 is being lowered, the lifting guide 4130 may slide downward in the guide groove 4016a, and at least a portion of the lifting guide 4130 may be deflected from the guide groove 4016a. Accordingly, the air flow control lifting unit 4100 can be lowered by as much as a length by which the lifting guide 4130 is deflected from the guide groove 4016a.

[000509] Furthermore, as illustrated in FIG. 73, when the air flow control lifting unit 4100 is being lifted, the lifting guide 4130 can slide upward in the guide groove 4016a, and the lifting guide 4130 can be inserted into the guide groove 4016a. Accordingly, the air flow control lifting unit 4100 can be lifted as much as a length by which the lifting guide 4130 is inserted into the guide groove 4016a.

[000510] When the air flow control lift unit 4100 is raised, an upper surface of the air flow control lift unit 4100 may be disposed adjacent to a lower surface of the drain tray 4016.

[000511] The air flow control elevator unit 4100 may include a driving device (not illustrated) configured to elevate the air flow control elevator unit 4100. The driving device (not illustrated) may include an element, such as a rack pinion, and a driving motor, and move the air flow control elevator unit 4100 in the vertical direction.

[000512] However, the embodiments are not limited to yet another embodiment of the present disclosure, and the lift guide 4130 may guide the upward movement of the air flow control lift unit 4100, when inserted into a guide groove, provided in an element other than the drain pan 4016. That is, the lifting guide 4130 may be inserted into a guide groove, in any element that may be provided within the upper housing 4011, or a separate guide element may be arranged .

[000513] When the air flow control lifting unit 4100 is lowered, an outer circumferential surface of the lifting guide 4130 may form one side of the discharge flow passage 4050. That is, when the air flow control lifting unit ar 4100 is lowered, the lifting guide 4130 is deflected from the guide groove 4106a and exposed to the outside. An exposed surface of the lifting guide 4130 is arranged to contact a side of the discharge flow passage 4050 and form a side of the discharge flow passage 4050.

[000514] Specifically, the discharge flow passage 4050 can be provided in a ring-shaped space, as it is divided by an inner circumferential surface of the upper housing 4011 and an outer circumferential surface 4100 of the air flow control lift unit. 4100, or be divided by the air flow control lift unit 4100 and outer circumferential surface of the lift guide 4130, when the air flow control lift unit 4100 is lowered. Each of upper housing 4011 and air flow control lift unit 4100 may be formed into a substantially cylindrical shape, as described above, and a ring-shaped space may be formed.

[000515] However, the embodiments are not limited to yet another embodiment of the present disclosure, and the discharge flow passage 4050 may be provided in various forms, according to the shapes of the upper housing 4011 and the unit airflow control elevator unit 4100. That is, when the inner circumferential surface of the upper housing 4011 and the airflow control elevator unit 4100 are formed into an elliptical shape, or a shape that has a curved surface, the passage of discharge flow 4050 can be formed as a space having a corresponding shape.

[000516] A divider 4051, which extends in a direction corresponding to a circumferential direction of the discharge flow passage 4050, for partitioning a portion of the discharge flow passage 4050, may be provided within the discharge flow passage 4050.

[000517] Divider 4051 may extend from a side adjacent to outlet 4056, or may extend from lower housing 4012, toward the interior of discharge flow passage 4050. However, embodiments are not limited to yet another embodiment of the present disclosure, and the divider 4051 may extend from a side of the upper housing 4011, toward the interior of the discharge flow passage 4050.

[000518] By divider 4051, the discharge flow passage 4050, adjacent to the outlet 4056, can be divided into an inner circumferential discharge flow passage 4052 and an external circumferential discharge flow passage 4053. Specifically, the passage inner circumferential discharge flow passage 4052 may be formed between the divider 4051 and the outer circumferential surface 4110 of the air flow control lifter unit 4100, which forms the inner circumferential surface of the discharge flow passage 4050, and the flow passage outer circumferential discharge port 4053 may be formed between the divider 4051 and the inner circumferential surface of the upper housing 4011, forming the outer circumferential surface of the discharge flow passage 4050.

[000519] Because the divider 4051 is extended from a side adjacent to the outlet 4056, as described above, the outlet 4056, connected to the internal circumferential discharge flow passage 4052, can be defined as a first outlet 4054, and the outlet 4056, connected to the external circumferential discharge flow passage 4053, can be defined as a second outlet 4055.

[000520] That is, the outlet 4056 can be divided into a plurality of outlets, by the divider 4051. In this sense, the air, which passes through the discharge flow passage 4050, can be discharged to the external side of the housing 4010, through from the first outlet 4054 or the second outlet 4055, along the inner circumferential discharge flow passage 4052 or the outer circumferential discharge flow passage 4053.

[000521] As described above, the air conditioning apparatus 4001, according to an embodiment of the present disclosure, includes the discharge flow passage 4050 provided in the form of a ring, and the outlet 4056, having at least one portion corresponding ring-shaped discharge flow passage 4050.

[000522] In the case of a conventional air conditioning apparatus, a housing and a heat exchanger are provided in a quadrilateral shape and, accordingly, an outlet is formed in a quadrilateral shape. Due to the fact that the outlet is provided in quadrilateral form, the outlet cannot be arranged to cover the entire external portion of a heat exchanger along a perimeter of the heat exchanger. In this regard, there are problems, in which a section, from which the discharged air flow is discharged, is limited and the air flow is not smoothly distributed to a portion without an outlet.

[000523] However, the air conditioning apparatus 4001, still according to another embodiment of the present disclosure, can provide airflow in all directions, without a blind spot, by having the discharge flow passage 4050 provided for in a ring shape, and the outlet 4056 having a ring shape corresponding to that of the discharge flow passage 4050.

[000524] Due to the fact that the outlet of the air conditioning apparatus, still according to another embodiment of the present disclosure, has a ring shape, as described above, unlike the conventional air conditioning apparatus, a blade, configured to control the flow of discharged air, it is difficult to be arranged inside the outlet. It is inconvenient to arrange a blade shaft within the ring-shaped outlet, and it is difficult for a blade to rotate within the ring-shaped outlet. In this sense, the air conditioning apparatus 4001, including the ring-shaped discharge flow passage 4050, in still another embodiment of the present disclosure, has to control the flow of discharged air, which is discharged from the output 4056, by an element other than a blade.

[000525] To this end, the air flow control elevator unit 4100, described above, and the air flow control element 4200, which will be described below, can be activated to control the flow of discharged air. Specifically, the air conditioning unit 4001 must form a downward airflow, which centralizes the airflow downwards, or a broad airflow, which releases airflow in all directions, according to the circumstances, and forms the air flow, according to the user's needs.

[000526] That is, although an air conditioning apparatus, including a blade, controls the downward air flow and a broad air flow by changing an angle of arrangement of the blade, the air conditioning apparatus 4001, still according to another embodiment of the present disclosure, can control the downward airflow and broad airflow by driving the airflow control lift unit 4100 and the airflow control element 4200.

[000527] Furthermore, when the flow of discharged air is controlled without the use of a blade, as in another embodiment of the present disclosure, the problems, in which an amount of discharged air is decreased, due to the air flow being interfered by a blade, and the flow noise being increased, due to the turbulent flow generated around the blade, can be resolved.

[000528] A curved portion 4111, including a curved and downwardly extending surface, may be provided below the outer circumferential surface 4110 of the air flow control elevator unit 4100. Specifically, the curved portion 4111 has a shape curved, formed in an outer direction of a radial direction of the discharged flow passage 4050, and may extend to an inner side of the air flow control lift unit 4100.

[000529] In this sense, the first outlet 4054 can be formed by a lower end of the curved portion 4111 and a lower end of the divider 4051.

[000530] The air, which passes through the internal circumferential discharge flow passage 4052, is discharged toward the outside of the housing 4010, through the first outlet 4054, along the curved portion 4111. This air is discharged through the first outlet 4054, along the curved portion 4111. In this sense, the air, to be discharged through the first outlet 4054, forms the discharged air flow in a direction corresponding to the outward direction of the radial direction of the discharge flow passage 4050.

[000531] That is, the air, to be discharged through the first outlet 4054, can form a broad air flow, which spreads in all directions.

[000532] Furthermore, the air, which is discharged through the second outlet 4055, along the external circumferential discharge flow passage 4053, can be discharged in a downward direction, towards which the second outlet 4055 is directed. the air, being discharged through the second outlet 4055, can form a downward airflow, which is directed downwards.

[000533] Therefore, when the inner circumferential discharge flow passage 4052 and the first outlet 4054 are controlled, or the outer circumferential discharge flow passage 4053 and the second outlet 4055 are controlled, ample air flow and air flow offspring can be generated selectively.

[000534] That is, when the inner circumferential discharge flow passage 4052 and the first outlet 4054, or the outer circumferential discharge flow passage 4053 and the second outlet 4055 are opened and closed alternately, ample air flow and the flow of descending air can be formed selectively.

[000535] Specifically, when the inner circumferential discharge flow passage 4052 or the first outlet 4054 is open and the outer circumferential discharge flow passage 4053 or the second outlet 4055 is closed, all air to be discharged from the housing 4010, can be discharged along the curved portion 4111 and form a broad airflow.

[000536] Furthermore, when the inner circumferential discharge flow passage 4052 or the first outlet 4054 is closed, and the outer circumferential discharge flow passage 4053 or the second outlet 4055 is open, all air to be discharged from the housing 4010, can be discharged through the second outlet 4055 and form a downward airflow.

[000537] The inner circumferential discharge flow passage 4052, or the first outlet 4054, can be opened and closed by the air flow control lift unit 4100. When the air flow control lift unit 4100 is raised, a closure portion 4112, provided on one side of the curved portion 4111, may be provided to be adjacent to a lower end portion of the divider 4051, as illustrated in FIG. 73, and close the inner circumferential discharge flow passage 4052 or the first outlet 4054. Here, the outer circumferential surface of the air flow control lifting device 4100 may close a space of the first outlet 4054 and restrict the air flow. , to be discharged, from the first outlet 4054, through the internal circumferential discharge flow passage 4052.

[000538] The closure portion 4112 may be provided as a part of the curved portion 4111, as in yet another embodiment of the present disclosure. However, the embodiments are not limited in this respect, and the closing portion 4112 may be a separate element disposed on the outer circumferential surface 4110.

[000539] Furthermore, the closing portion 4112 can be disposed adjacent to the lower end of the divider 4051 and block a flow passage formed by the first outlet. The embodiments are not, in this respect, limited, and the closing portion 4112 may be arranged to contact the lower end of the divider 4051 and completely close the first outlet 4054.

[000540] When the air flow control lifting unit 4100 is being lowered, a gap may be formed between the closing portion 4112 and the lower end of the divider 4051. In this regard, the first outlet 4054 may be opened and the air , to be discharged, may be discharged through the first outlet 4054 along the inner circumferential discharge flow passage 4052.

[000541] The external circumferential discharge flow passage 4053 and the second outlet 4055 can be opened and closed by the air flow control element 4200.

[000542] The air flow control element 4200 may be provided in a plate form corresponding to that of the external circumferential discharge flow passage or second outlet 4055. That is, the air flow control element 4200 may have a size corresponding to an area at least that of the second outlet 4055, to be capable of closing the second outlet 4055. Furthermore, the airflow control element 4200 may be provided in a sliding manner. The air flow control element 4200 may be disposed in the outer circumferential discharge flow passage 4053 or in the second outlet 4055, slide, as illustrated in FIG. 73, and be inserted into a sliding groove 4210, provided on an external side in the radial direction of the discharge flow passage 4050.

[000543] The airflow control element 4200 may include a driver device (not illustrated) configured to slide the airflow control element 4200. The driver device (not illustrated) may include an element such as a rack and pinion. a drive motor, and slide the 4200 airflow control element.

[000544] When the air flow control element 4200 is disposed in the external circumferential discharge flow passage 4053 or the second outlet 4055, as illustrated in FIG. 72, the second output 4055 is closed. In this sense, the air, to be discharged to the external side of the housing 4010, is prevented from being discharged through the second outlet 4055.

[000545] However, when the airflow control element 4200 slides into the sliding groove 4210, as illustrated in FIG. 73, the external circumferential discharge flow passage 4053 or the second outlet 4055 can be opened and the air, to be discharged, can be discharged through the second outlet 4055. Due to the fact that the second outlet 4055 is formed in the direction of the lower side from housing 4010, air discharged through second outlet 4055 can form a downward airflow.

[000546] The airflow control element 4200 is not limited to yet another embodiment of the present disclosure. The external circumferential discharge flow passage 4053 or the second outlet 4055 can be opened and closed by rotating the air flow control element 4200 as well as sliding the air flow control element 4200. That is, the external circumferential discharge flow 4053 or the second outlet 4055 can be opened and closed according to an angle, in which the air flow control element 4200 is rotated.

[000547] As described above, the air discharged through the first outlet 4054 can form a broad airflow, and the air discharged through the second outlet 4055 can form a downward airflow. In this regard, when the airflow control lifting unit 4100 is being lowered and the airflow control element 4200 is disposed in the outer circumferential discharge flow passage 4053 or the second outlet 4055, as illustrated in FIGS. 72 and 74, the first output 4054 is opened and the second output 4055 is closed. In this sense, all air discharged to the external side of the housing 4010 is discharged through the first outlet 4054, and can thus form a broad air flow.

[000548] Furthermore, when the airflow control lifting unit 4100 is being lifted and the airflow control element 4200 slides and is inserted into the sliding groove 4210, as illustrated in FIGS. 73 and 75, the first output 4054 is closed and the second output 4055 is opened. In this sense, all the air discharged to the external side of the housing 4010 is discharged through the second outlet 4055, and can thus form a downward air flow.

[000549] In this regard, the air flow control elevating device 4100 and the air flow control element 4200 can control a direction of the discharged air flow by alternately opening or closing the internal circumferential discharge flow passage 4052 or the first outlet 4054, and the external circumferential discharge flow passage 4053 or the second outlet 4055.

[000550] However, the embodiments are not limited to the embodiment of the present disclosure, and the air flow control lift device 4100 and the air flow control element 4200 can discharge air by partially opening the air passage. inner circumferential discharge flow passage 4052 or the first outlet 4054, and the outer circumferential discharge flow passage 4053 or the second outlet 4055, instead of completely closing or opening the inner circumferential discharge flow passage 4052 or the first outlet 4054, and the external circumferential discharge flow passage 4053 or the second outlet 4055.

[000551] In this sense, an amount of air flow discharged, from each of the first outlet 4054 and second outlet 4055, is changed according to a degree, to which each of the first outlet 4054 and second outlet 4055 is opened . The airflow discharged from the first outlet 4054 and the airflow discharged from the second outlet 4055 can be mixed and form the airflow discharged in various directions.

[000565] However, as in yet another embodiment of the present disclosure, the inlet 5020 and the suction flow passage 5021 may be arranged in an air flow control guide unit 5100, which will be described below. The air flow control guide unit 5100 may form at least a portion of the housing 5010 and control the flow of discharged air to be discharged out of the housing 5010 by the lifting movement.

[000566] A discharge flow passage 5050, provided to allow air, drawn in through the inlet 5020, to exchange heat with the heat exchanger 5030 and be discharged, may be formed on an external side, in a radial direction of the inlet 5020, and on an external side, in a radial direction of the heat exchanger 5030. The discharge flow passage 5050 may be substantially ring-shaped when viewed in a vertical direction. However, the embodiments are not limited in this respect, and the discharge flow passage 5050 may also be provided to include a curved section.

[000567] The discharge flow passage 5050 may be provided in a ring shape by the heat exchanger 5030, provided in a ring shape, and housing 5010 provided in a cylindrical shape. One side of the discharge flow passage 5050 may be connected to the heat exchanger 5030, and the other side thereof may be connected to an outlet 5056, provided near the lower housing 5012.

[000568] With the above structure, the air conditioning apparatus 5001 can draw in air from a lower side, cool and heat the air, and then discharge the air back to the lower side.

[000569] A grille (not illustrated) can be attached to an upper side of the inlet 5020, to filter dust from the air, which will be drawn through the inlet 5020.

[000570] Heat exchanger 5030 may be provided within housing 5010 and may be arranged in an air flow passage between inlet 5020 and outlet 5056. Heat exchanger 5030 may be formed by a tube (not illustrated), with refrigerant gas flowing therethrough, and a head (not illustrated), connected to an external refrigerant gas pipe, for supplying or collecting the refrigerant gas in the pipe. A heat exchange fin can be provided on the tube to expand a heat dissipation area.

[000571] The heat exchanger 5030 may have substantially a ring shape when viewed in the vertical direction. The shape of the heat exchanger 5030 may correspond to the shape of the housing 5010. The shape of the heat exchanger 5030 may correspond to the shape of the outlet 5056. The heat exchanger 5030 may be placed in a drain pan 5016, and the condensate generated in the Heat exchanger 5030 can be collected in drain pan 5016.

[000572] The blow fan 5040 may be provided inside, in a radial direction of the heat exchanger 5030. The blow fan 5040 may be a centrifugal fan, configured to draw in air in an axial direction and discharge air in a radial direction. A fan motor 5041, configured to drive the blower fan 5040, may be provided in the air conditioning apparatus 5001.

[000573] With the above configuration, the air conditioning apparatus 5001 can draw in air from an indoor space, cool the air, and then discharge the air back into the indoor space, or draw in air from an indoor space, heat the air and then discharge the air back into the internal space.

[000574] The air conditioning apparatus 5001 may further include a heat exchanger pipe 5031, connected to the heat exchanger 5030 from the outside of the housing 5010, and having refrigerant gas along it, and a drain pipe 5017, configured to discharge condensate collected in drain pan 5016 to the outside. The heat exchanger pipe 5031 and the drain pipe 5017 can be connected to the outside through one side of the upper housing 5011.

[000575] As described above, the air conditioning apparatus 5001, in still another embodiment of the present disclosure, includes the discharge flow passage 5050, formed in a ring shape, and the outlet 5056, formed in a ring shape. ring, and having at least a portion corresponding to the ring-shaped discharge flow passage 5050.

[000576] The discharge flow passage 5050 may include a first guide surface 5051 and a second guide surface 5052, provided in a lower portion and forming the ring-shaped discharge flow passage 5050. A ring-shaped space may be formed in an upper portion of the discharge flow passage 5050, by an inner circumferential surface of the upper housing 5011 and heat exchanger 5030, and a ring-shaped space may be formed in the lower portion of the discharge flow passage 5050, arranged below the heat exchanger 5030, by the first guide surface 5051, formed by an outer circumferential surface of the air flow control guide unit 5100, and the second guide surface 5052, formed by the inner circumferential surface of the upper housing 5011.

[000577] However, the embodiments are not limited to yet another embodiment of the present disclosure, and the first guide surface 5051 and the second guide surface 5052 may extend from the upper housing 5011 or the lower housing 5012, or they may extend from an intermediate housing, which may be provided between the upper housing 5011 and the lower housing 5012, although not illustrated. Furthermore, the first guide surface 5051 and the second guide surface 5052 may be formed in a separate configuration.

[000578] Each of the first guide surface 5051 and the second guide surface 5052 may include a curved portion 5053 provided in a curved shape and extending in an outward direction, in a radial direction of the discharge flow passage 5050. The curved portion 5053 may be provided on a side adjacent to outlet 5056.

[000579] The air, to be discharged from the outlet 5056 through the discharge flow passage 5050, may be discharged along the curved portion 5053, in a direction, in which the curved surface is bent. In this sense, the air, to be discharged from the outlet 5056, may be discharged towards the outer side of the housing 5010, along the outer direction of the radial direction of the discharge flow passage 5050, which is a direction, in which the curved portion 5053 extends.

[000580] As illustrated in FIG. 83, an air flow control projection 5200, configured to change a direction of air flow, to be discharged from the outlet 5056, may be disposed in the outward direction of the radial direction of the outlet 5056. The flow control projection airflow 5200 may include a discharge guide surface 5210, which projects to extend in a downward direction from the outlet 5056, and configured to guide airflow in the downward direction, into which the airflow control projection 5200 extends. .

[000581] The air flow control projection 5200 can be provided in a moving path of discharged air flow and change a discharge direction by colliding with the air to be discharged.

[000582] In a specific manner, as described above, the air, to be discharged, is directed to the outer part of the radial direction of the discharge flow passage 5050 or the outlet 5056, through the curved portion 5053, and forms a flow of ample air in all directions of the housing 5010. The broad airflow may collide with the airflow control projection 5200, descend along the discharge guide surfaces 5210, and be changed to downward airflow.

[000583] In this sense, the air, to be discharged from the air conditioning apparatus 5001, still according to another embodiment of the present disclosure, forms, to a large extent, the downward air flow, due to the flow control projection of air 5200.

[000584] According to the circumstances, the air conditioning unit 5001 should selectively form a broad airflow, in which the air spreads in all directions, and downward airflow, in which the discharged airflow is centered down. Here, due to the fact that the air conditioning apparatus 5001 according to the embodiment of the present disclosure largely forms a downward air flow, a problem occurs in controlling the flow of discharged air.

[000585] In the case of a conventional air conditioning apparatus, a housing and a heat exchanger are provided in a quadrilateral shape and, accordingly, an outlet is formed in a quadrilateral shape. Because the outlet is provided in a quadrilateral format, the outlet cannot be arranged to cover the entire outer portion in the radial direction along a perimeter of the heat exchanger. In this regard, there are problems, in which a section, from which the discharged air flow is discharged, is limited, and a blind spot is formed, due to the air flow not being easily distributed to a portion without an outlet.

[000586] However, the air conditioning apparatus 5001, still according to another embodiment of the present disclosure, can distribute the air flow in all directions, without a blind spot, with the discharge flow passage 5050 formed in a ring shape and the outlet 5056 having a ring shape corresponding to that of the discharge flow passage 5050.

[000587] Due to the fact that the outlet of the air conditioning unit, still according to another embodiment of the present disclosure, has a ring shape, as described above, unlike the conventional air conditioning unit, it is difficult for a blade, configured to control the flow of discharged air, be arranged within the outlet. That is, because of the inconvenience of arranging a blade shaft within the ring-shaped outlet provided, it is difficult to rotate a blade within the ring-shaped outlet. Therefore, the air conditioning apparatus 5001, including the ring-shaped discharge flow passage 5050, in accordance with yet another embodiment of the present disclosure, needs to control the flow of discharged air, which is discharged from the outlet. 5056, by an element other than a blade.

[000588] Therefore, the air conditioning unit can drive the air flow control guide unit 5100, which will be described below, to control the flow of discharged air. Specifically, although an air-conditioning apparatus including a blade controls the downward airflow and broad airflow by changing an angle of arrangement of the blade, the air-conditioning apparatus 5001, still in accordance with another form of carrying out the present disclosure, you can control the downward airflow and broad airflow by operating the airflow control guide unit 5100.

[000589] Furthermore, when discharged air flow is controlled without using a blade, as in yet another embodiment of the present disclosure, the problems, in which an amount of discharged air decreases, due to the air flow being interfered with by a blade, and the flow noise increases, due to the turbulent flow generated around the blade, can be resolved.

[000590] Next, the air flow control guide unit 5100 will be described in detail.

[000591] FIG. 84 is an enlarged view of the portion marked in FIG. 82, FIG. 85 is an enlarged view of a portion corresponding to the portion marked in FIG. 82, when the air flow control guide unit of the air conditioning apparatus is arranged in a first position, still in accordance with another embodiment of the present invention, FIG. 86 is a perspective view, when the air flow control guide unit of the air conditioning apparatus is arranged in a second position, still in accordance with another embodiment of the present disclosure, and FIG. 87 is a perspective view, when the air flow control guide unit of the air conditioning apparatus is arranged in the first position, still in accordance with another embodiment of the present disclosure.

[000592] As illustrated in FIGS. 84 and 85, the air flow control guide unit 5100 may be disposed on a central side of the lower housing 5012. The air flow control guide unit 5100 may be provided in a substantially cylindrical shape.

[000593] The outer circumferential surface of the air flow control guide unit 5100 may form the first guide surface 5051 of the discharge flow passage 5050, and the inner circumferential surface of the guide unit 5100 may form the suction flow passage 5021 , configured to connect inlet 5020 to blower fan 5040, to cause air drawn through inlet 5020 to be introduced into blower fan 5040.

[000594] The air flow control guide unit 5100 may be disposed below the drain tray 5016 and may be provided to be suspended below the drain tray 5016. The air flow control guide unit 5100 may be lowered and placed in a first position H1, and can be lifted and placed in a second position H2. That is, the air flow control guide unit can be provided to be suspended between the first position H1 and the second position H2.

[000595] The air flow control guide unit 5100 may include a lifting guide 5130, which extends upwardly. When the air flow control guide unit 5100 is being lifted, the lifting guide 5130 can guide the air flow control guide unit 5100, so that the air flow control guide unit 5100 moves upward or downward. down.

[000596] Specifically, the drain tray 5016 may include a guide groove 5016a provided to correspond to the lifting guide 5130 and the lifting of the air flow control guide unit 5100 may be done by the lifting guide 5130, sliding vertically in guide groove 5016a.

[000597] As illustrated in FIG. 84, when the air flow control guide unit 5100 is being lowered and disposed in the first position H1, the lifting guide 5130 may slide downwardly in the guide groove 5016a and at least a portion of the lifting guide 5130 may be displaced from guide groove 5016a. Accordingly, the air flow control guide unit 5100 can be lowered by as much as a length by which the lifting guide 5130 is displaced from the guide groove 5016a.

[000598] Furthermore, as illustrated in FIG. 83, when the air flow control guide unit 5100 is being lifted and arranged in the second position H2, the lifting guide 5130 can slide upward into the groove 5016a, and the lifting guide 5130 can be inserted into the guide groove 5016a . Accordingly, the air flow control guide unit 5100 can be lifted as much as a length by which the lifting guide 5130 is inserted into the guide groove 5016a.

[000599] When the air flow control guide unit 5100 is lifted and disposed in the second position H2, an upper surface of the air flow control guide unit 5100 may be arranged to be adjacent to a lower surface of the drain tray 5016.

[000600] The air flow control guide unit 5100 may include a drive device (not illustrated) configured to raise the air flow control guide unit 5100. The drive device (not illustrated) may include an element such as a pinion rack and a drive motor, and move the 5100 air flow control guide unit in the vertical direction.

[000601] However, the embodiments are not limited to yet another embodiment of the present disclosure, and the lifting guide 5130 can guide the upward movement of the airflow control guide unit 5100 by being inserted into a groove guide, provided in an element other than the drain pan 5016. That is, the lifting guide 5130 may be inserted into a guide groove in any element that may be provided within the upper housing 5011, or may be arranged in a separate guide element.

[000602] When the air flow control guide unit 5100 is lowered and placed in the first position H1, an outer circumferential surface of the lifting guide 5130 may form one side of the first guide surface 5051 of the discharge flow passage 5050. This is, when air flow control guide unit 5100 is lowered, the lifting guide 5130 is displaced from the guide groove 5106a and exposed to the outside. An exposed surface of the lifting guide 5130 is arranged to contact a side of the first guide surface 5051 of the discharge flow passage 5050, and forms a side of the first guide surface 5051 of the discharge flow passage 5050.

[000603] That is, when the air flow control guide unit 5100 is arranged in the first position H1, the inner circumferential surface of the discharge flow passage 5050 extends downwardly as much as a length, by which the guide elevation 5130 is exposed and, in this sense, the discharged air flow can be discharged from a lower side, compared to when the air flow control guide unit 5100 is arranged in the second position H2.

[000604] As illustrated in FIGS. 83 and 85, when the air flow control guide unit 5100 is arranged in the second position H2, the air, to be discharged from the outlet 5056, can be guided downwardly by the air flow control projection 5200, provided in a discharge area, and become a downward airflow.

[000605] However, as illustrated in FIGS. 84 and 86, when the air flow control guide unit 5100 is lowered and arranged in the first position H1, an air discharge area, to be discharged from the outlet 5056, may be provided below the discharge area of the second H2 position, and the largest portion of the air, to be discharged, may not collide with the airflow control projection 5200, direct to the outer direction of the radial direction of the outlet 5056 and become a broad airflow .

[000606] That is, the air flow control guide unit 5100 can be arranged in the first position H1, by being lowered, and control the discharged air flow, so that the discharged air flow becomes a wide air flow , and can be arranged in the second position H2, by being raised, and controlling the discharged air flow, so that the discharged air flow becomes downward air flow.

[000607] In other words, with respect to the air flow control guide unit 5100, the first position H1 may be a section, in which the air flow control guide unit 5100 controls the broad air flow, and the second position H2 may be a section, in which the airflow control guide unit controls the downward airflow.

[000608] Next, an air flow control guide unit 5300 of an air conditioning unit 5001', still in accordance with another embodiment of the present disclosure, will be described. Due to the fact that the elements, other than the elements that will be described below, are the same as those of the air conditioning apparatus 5001, still in accordance with another embodiment of the present disclosure described above, the superimposed descriptions will be omitted. Unlike the embodiment described above, the air conditioning apparatus 5001', still in accordance with another embodiment of the present disclosure, does not include the air flow control projection 5200.

[000609] FIG. 88 is a rear view of an air conditioning apparatus, still in accordance with another embodiment of the present disclosure, FIG. 89 is a cross-sectional side view of the air conditioning apparatus, still in accordance with another embodiment of the present disclosure, FIG. 90 is an enlarged view of a portion marked in FIG. 89, FIG. 91 is an enlarged view of a portion corresponding to the portion marked in FIG. 89, when an air flow control guide unit of the air conditioning apparatus is arranged in a first position, still in accordance with another embodiment of the present disclosure, FIG. 92 is a perspective view, when the air flow control guide unit is arranged in a second position, in still another embodiment of the present disclosure, and FIG. 93 is a perspective view, when the air flow control guide unit is arranged in the first position, still in accordance with another embodiment of the present disclosure.

[000610] As illustrated in FIG. 88, the air flow control guide unit 5300 may be provided in the form of a ring on an external side in the radial direction of the outlet 5056.

[000611] As described above, the air, to be discharged through the outlet 5056, is directed towards the outward direction of the radial direction of the discharge flow passage 5050 or the outlet 5056, along the curved portion 5053. This is to control airflow by arranging the 5300 airflow control guide unit in a discharge direction.

[000612] Although the air flow control guide unit 5300 is provided in a ring shape corresponding to that of the outlet 5056, as in yet another embodiment of the present disclosure, the embodiments are in this respect not limited, and the 5300 air flow control guide unit can be supplied in various forms. However, for effective airflow control, the airflow control guide unit 5300 preferably has a shape corresponding to that of the outlet 5056, and is provided on the external side of the outlet 5056. Accordingly, when the outlet 5056 is provided in a form other than a ring, the air flow control guide unit 5300 may also be provided in a form other than a ring.

[000613] As illustrated in FIGS. 90 and 91, the air flow control guide unit 5300 can slide between a first position H3 and a second position H4. The first position H1 can be defined as a position, in which the air flow control guide unit 5300 is not disposed in a moving path of the discharged air flow, and the second position H4 can be defined as a position, in which the airflow control guide 5100 is disposed in the moving path of the discharged airflow.

[000614] The description will be given based on the illustrated air flow control guide unit 5300. The air flow control guide unit 5300, placed in the first position H3, is inserted into an insertion groove 5310, provided within the housing 5010, and is inserted into the housing 5010. Specifically, the air flow control guide unit 5300 is inserted into the insertion groove 5310, provided in the housing 5010, when sliding, and arranged so as not to be exposed to the outside.

[000615] The air flow control guide unit 5300, placed in the second position H4, slides from the first position H3 and projects to the external side of the housing 5010. Specifically, the air flow control guide unit air 5300 slides from the insertion groove 5310, is displaced from the insertion groove 5310, passes through the lower housing 5012, projects from a lower side of the housing 5010, and is placed in the moving path of the discharged air flow.

[000616] The air flow control guide unit 5300 may include a driver device (not illustrated) configured to slide the air flow control guide unit 5300. The driver device (not illustrated) may include an element such as as a rack pinion and drive motor, and slide the 5300 airflow control guide unit in the vertical direction.

[000617] However, the embodiments are not limited in this respect, and the airflow control guide 5300 can move between the first position H3 and the second position H4, using several different sliding methods.

[000618] As described above, the discharged air flow, to be discharged from the outlet 5056, is a broad outward airflow in the radial direction of the outlet 5056. The air flow control guide unit 5300 can be placed in the second position H4, control the broad airflow, to be discharged, and change the broad airflow to the downflow flow, going in the direction below outlet 5056.

[000619] Furthermore, when the air flow control guide unit 5300 is placed in the first position H3, the air flow control guide unit 5300 is not arranged in a direction, in which the discharged air flow is formed , and does not limit the broad airflow to be discharged through outlet 5056.

[000620] That is, the air conditioner 5001' can form a wide air flow when the air flow control guide unit 5300 is arranged in the first position H3, and the air conditioner 5001' can form a downward airflow, when the airflow control guide unit 5300 is arranged in the second position H4.

[000621] Next, an air flow control guide unit 5400 of the air conditioning device 5001' will be described, still in accordance with another embodiment of the present disclosure. Due to the fact that elements, other than the elements that will be described below, are the same as those of the air conditioning apparatus 5001, still in accordance with another embodiment of the present disclosure described above, overlapping descriptions will be omitted.

[000622] FIG. 94 is an enlarged cross-sectional side view of a portion, when an air flow control guide unit of the air conditioning apparatus is arranged in a first position, in accordance with still another embodiment of the present disclosure; and FIG. 95 is an enlarged cross-sectional side view of a portion, when the air flow control guide unit of the air conditioning apparatus is arranged in a second position, still in accordance with another embodiment of the present invention.

[000623] As illustrated in FIGS. 94 and 95, the air flow control guide unit 5400 may be provided on an external side, in the radial direction of the outlet 5056.

[000624] As described above, the air, to be discharged through the outlet 5056, heads towards the outward direction of the radial direction of the discharge flow passage 5050, or towards the outlet 5056, along the curved portion 5053. That is to control airflow by arranging the 5300 airflow control guide unit in a discharge direction.

[000625] The air flow control guide unit 5400 may include a rotary shaft 5410 provided at one end of the guide unit 5400. The guide unit 5400 may move between a first position H5 and a second position H6, when rotating about the rotary axis 5410.

[000626] That is, when a position in which the air flow control guide unit 5400 faces the lower housing 5012, as illustrated in FIG. 94, is defined as the first position H5, and a position, in which the air flow control guide unit 5400 rotates about the rotary axis 5410 from the first position H5 and is disposed in a direction perpendicular to the lower housing 5012, is set to the second position H6, the airflow control guide unit 5400 can change the broad airflow to be discharged through the outlet 5056 to the downward airflow when arranged in the second position H6.

[000657] An operation, in which the air flow discharged from the air conditioning apparatus 6001, illustrated in FIG. 96, is controlled, will be described with reference to FIGS. 99 to 101.

[000658] With reference to FIG. 99, when the air conditioning apparatus 6001 does not operate, the air flow control device 6100 is disposed in a substantially horizontal direction at the outlet 6021.

[000659] With reference to FIG. 100, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 6021 of the air conditioning apparatus 6001, to be along the outer side in the radial direction of the outlet 6021, the opening and closing element 6101 of the air flow control device 6100 is rotated counterclockwise, by a predetermined angle, about the guide shaft 6102, as an axis of rotation, by a user command. Here, predetermined angle can be adjusted, so that the opening and closing element 6101 can guide the air, which passes through the outlet 6021, towards the first guide surface 6014.

[000660] The air, guided towards the first guide surface 6014, by the opening and closing element 6101, can be reflected by the first guide surface 6014 and spread widely outwards, in the radial direction of the outlet 6021. That is, the air conditioning apparatus 6001 can discharge air to a portion away from the air conditioning apparatus 6001 and in this regard, the air conditioning apparatus 6001 can gently cool or heat the entire internal space. Here, a portion of air, which is not reflected by the first guide surface 6014 and is discharged along the first guide surface 6014, may spread towards the outer side, in the radial direction of the outlet 6021, through the Coanda curved portion 6014a, provided on an end portion of the first guide surface 6014.

[000661] On the other hand, with reference to FIG. 101, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 6021 of the air conditioning apparatus 6001, to be along the inner side, in the radial direction of the outlet 6021, the opening member and closure 6101 of the air flow control device 6100 is rotated clockwise, by a predetermined angle, about the guide shaft 6102, as an axis of rotation, through a user command. Here, the predetermined angle can be adjusted, so that the opening and closing element 6101 can guide the air, which passes through the outlet 6021, towards the second guide surface 6018.

[000662] The air, guided towards the second guide surface 6018, by the opening and closing element 6101, can be reflected by the second guide surface 6018 and be discharged in a substantially vertical direction. That is, a direction of the discharged air flow can be adjusted to be closer to the inner side, in the radial direction of the outlet 6021, compared to a case, in which the air is reflected by the first guide surface 2014 and discharged. In this regard, the air conditioning apparatus 6001 can intensively cool or heat a portion adjacent to the air conditioning apparatus 6001. Here, a portion of air, which is not reflected by the second guide surface 6018 and is discharged along the second guide surface 6018 , may be discharged in a substantially vertical direction by the Coanda curved portion 6018a, provided at an end portion of the second guide surface 6018, and form a centralized air flow.

[000664] In this way, according to the embodiment illustrated in FIGS. 97 to 101, a direction of the discharged air flow can be controlled according to the user's need, even when the outlet 6021 is provided in a circular shape.

[000665] FIGS. 102 and 103 are views, which also illustrate another embodiment of the air conditioning apparatus 6001, illustrated in FIG. 96.

[000666] An air conditioning apparatus 6002, according to yet another embodiment, will be described with reference to FIGS. 102 and 103. However, similar reference numbers may be assigned to elements, which are the same as those of the embodiments described above, and their description may be omitted.

[000667] The air conditioning apparatus 6002 may further include a guide rib 6210, configured to guide air past the air flow control device 6100.

[000668] The air conditioning apparatus 6002 may include the air flow control device 6100, in accordance with the embodiment illustrated in FIG. 99. The air flow control device 6100 may include the opening and closing member 6101, configured to guide air, which has passed through the heat exchanger 6030, toward the first guide surface 6014 or the second guide surface 6018, and the guide shaft 6102, having the opening and closing element 6101 fixed and coupled thereto.

The guide rib 6210 may be provided to be progressively inclined outwardly in the radial direction of the outlet 6021 in the direction in which the air is discharged. The guide ribs 6210 may extend consecutively along the circumferential direction of the outlet 6021. However, the embodiments are not in this respect limited, and the guide ribs 6210 may be provided to be spaced apart at intervals. predetermined, as they extend along the circumferential direction of the outlet 6021. Here, the guide rib 6210 may be arranged to correspond to a section, in which the air flow control device 6100 is disposed.

[000670] The guide rib 6210 can guide the air, which passed through the air flow control device 6100.

[000671] Specifically, with reference to FIG. 102, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 6021 of the air conditioning apparatus 6002, to lie along the outer side, in the radial direction of the outlet 6021, the opening member and closure 6101 of the air flow control device 6100 is rotated counterclockwise, by a predetermined angle, about the guide axis 6102, as an axis of rotation, by a user command. Here, the predetermined angle can be adjusted, so that the opening and closing element 6101 can guide the air, which passes through the outlet 6021, towards the first guide surface 6014.

[000672] The air guided in the direction of the first guide surface 6014, by the opening and closing element 6101, can be reflected by the first guide surface 6014 and be widely spread outwards, in the radial direction of the outlet 6021. Here, the rib guide 6210 can guide a portion of air reflected by the first guide surface 6014. Specifically, a first surface 6211 of the guide rib 6210, facing the first guide surface 6014, can guide a portion of air reflected by the first guide surface 6014, of so that the portion of air can be discharged to the outside in the radial direction of the outlet 6021. Here, the portion of air reflected by the first guide surface 6014 can be guided to the outside in the radial direction of the outlet 6021 along of the first surface 6211 of the guide rib 6210, by the Coanda effect.

[000673] Furthermore, with reference to FIG. 103, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 6021 of the air conditioning apparatus 6002, to be along the inner portion, in the radial direction of the outlet 6021, the opening member and closure 6101 of the air flow control device 6100 is rotated clockwise, by a predetermined angle, about the guide shaft 6102, as an axis of rotation, through a user command. Here, the predetermined angle can be adjusted, so that the opening and closing element 6101 can guide the air passage through the outlet 6021 towards the second guide surface 6018.

[000674] The air, guided towards the second guide surface 6018 by the opening and closing element 6101, can be reflected by the second guide surface 6018 and be discharged in a substantially vertical direction. Here, the guide rib 6210 can guide a portion of air reflected by the second reflective surface 6018. Specifically, a second surface 6212 of the guide rib 6210, facing the second reflective surface 6018, can guide the portion of air, reflected by the second reflective surface 6018, and moving the portion of air again toward the air to be discharged in a substantially vertical direction. In this sense, the air, reflected by the second surface 6212 of the guide rib 6210, may meet the air, to be discharged in a substantially vertical direction, by the second reflecting surface 6018, and be discharged in the substantially vertical direction, together with the air, to be discharged by the second reflecting surface 6018.

[000675] In this way, according to the embodiment illustrated in FIGS. 102 and 103, because the air, which passed through the air flow control device 6100, is secondarily guided by the guide rib 6210, the loss of a quantity of discharged air can be reduced and the efficiency of Cooling and heating can be increased.

[000676] FIG. 104 is a view, which also illustrates another embodiment of the air flow control device 6100 of the air conditioning apparatus 6001, illustrated in FIG. 99.

[000695] The opening and closing driving source 6331 can be provided inside the housing 6010, on the internal side, in the radial direction of the opening and closing element 6320. However, the embodiments are not, in this aspect, limited , and the opening and closing drive source 6331 may be provided inside the housing 6010, on the outside in the radial direction of the opening and closing member 6320, or may be provided outside the housing 6010. The opening and closing drive source 6331 could be an engine.

[000696] The opening and closing power transmitter 6332 can transmit energy, generated by the opening and closing drive source 6331, to the opening and closing element 6320, to allow the opening and closing element 6320 to rotate.

[000697] Specifically, the opening and closing power transmitter 6332 may be provided as a gear, and the opening and closing member 6320 may include a gear tooth 6323, formed on its inner circumferential surface and configured to receive power. , by being engaged with a gear of the opening and closing power transmitter 6332.

[000698] An operation, in which the air flow discharged from the air conditioning apparatus 6003, including the air flow control device 6300, illustrated in FIG. 104, is controlled, will be described with reference to FIGS. 105 to 108.

[000699] With reference to FIGS. 105 and 106, when the user attempts to set a direction of the flow of discharged air, which is discharged from the outlet 6021 of the air conditioning apparatus 6003, to be along the outer side, in the radial direction of the outlet 6021 (a first direction ), the opening and closing member 6320 of the air flow control device 6300 is rotated to a position to open the first section S3 of the guide member 6310 by a user command. In this sense, all the first sections S3 of the guide element 6310 are open and all the second sections S4 thereof are closed by the blocker 6322. In this sense, all the air, which passed through the heat exchanger 6030, passes through the 6300 airflow control, only through the first S3 sections.

[000700] Here, the air, which passes through the first section S3, can be guided towards the first reflecting surface 6014 by the first guide element 6311. The air guided towards the first reflecting surface 6014 is reflected by the first reflecting surface 6014 and spreads widely toward the outside, in the radial direction of the outlet 6021. That is, the air conditioning apparatus 6003 can discharge air toward a portion away from the air conditioning apparatus 6003 and gently cool or heat the entire internal space. Here, a portion of air, which is not reflected by the first reflecting surface 6014 and is discharged along the first reflecting surface 6014, may spread outwards, in the radial direction of the outlet 6021, by the Coanda curved portion 6014a provided in a portion from the end of the first reflective surface 6014.

[000701] On the other hand, with reference to FIGS. 107 and 108, when the user attempts to define a flow direction of discharged air, which is discharged from the outlet 6021 of the air conditioner 6003, to be along the inner part, in the radial direction of the outlet 6021 (a second direction ), the opening and closing member 6320 of the air flow control device 6300 is rotated to a position to open the second section S4 of the guide member 6310 by a user command. In this sense, all the second sections S4 of the guide element 6310 are opened, and all its first sections S3 are closed by the blocker 6322. In this sense, all the air, which passed through the heat exchanger 6030, passes through the flow control device. airflow 6300, only through the second S4 sections.

[000702] Here, the air, which passes through the second section S4, can be guided towards the second reflective surface 6018, by the second guide element 6312. The air, guided towards the second reflective surface 6018, is reflected by the second reflective surface 6018 and descends substantially in the vertical direction. That is, a direction of the discharged air flow is changed to be closer to the inner side, in the radial direction of the outlet 6021, compared to a case, in which the air is reflected by the first reflecting surface 6014 and is discharged. Therefore, the air conditioning apparatus 6003 can intensely cool or heat a portion adjacent to the air conditioning apparatus 6003. Here, the air, which is not reflected by the second reflective surface 6018 and is discharged along the second reflective surface 6018, can be discharged in a substantially vertical direction, by the curved Coanda portion 6018a, provided at an end portion of the second reflective surface 6018, and form a centralized air flow.

[000703] In this way, according to the embodiment illustrated in FIGS. 104 to 108, a direction of the discharged air flow can be controlled, according to a user's need, even when the outlet 6021 is provided in a circular shape.

[000704] As described above, the air conditioners 6001, 6002 and 6003, according to the present description, can control a flow direction of discharged air, which is discharged from the outlet 6021, having a circular shape with a relatively simple configuration and, because an outlet 6021 having a circular shape is provided, air can be discharged in all directions along the circumferences of the air conditioners 6001, 6002, and 6003, and the cooling blind spots and heating can be minimized.

[000705] Although the technical spirit of the present disclosure has been described above by particular embodiments, the scope of the present disclosure is not limited to embodiments. Various embodiments, which may be modified or altered, by one skilled in the art, within a scope that does not depart from the essence of the technical spirit of the present disclosure, set forth in the claims below, are to be understood as belonging to the scope of the present disclosure .
