Description

air conditioning unit

[0001] The present invention relates to an air conditioning device.

[0002] Air conditioning systems are designed to maintain the air in indoor spaces at optimal conditions, depending on their intended purpose. For example, in summer, air conditioning systems typically discharge indoor heat to the outside, lowering the indoor air temperature. Furthermore, in winter, air conditioning systems can increase the temperature of the exhaust air, ensuring that indoor temperatures remain relatively higher than outdoors.

[0003] Air conditioning units deliver heat-exchanged air to indoor spaces requiring air conditioning. However, they must be able to appropriately distribute the air based on the location of the user within the space. For example, the direction of air discharge must be adjusted to prevent direct airflow toward the user.

[0004] In particular, the air discharged from air conditioning devices that are installed adjacent to or in close contact with one wall of an indoor space, or installed in a window on the wall, such as stand-alone, wall-mounted, or window-type air conditioning devices, is often directly delivered to the user. For example, Korean Utility Model No. 20-0146110, which is Patent Document 1, illustrates an indoor unit of a wall-mounted air conditioning device, in which air is discharged at an angle downward through an outlet so that the heat-exchanged air can be directly delivered to the user.

[0005] In addition, in Korean Patent No. 10-0234964, which is Patent Document 2, the air conditioner is configured to discharge air toward the front lower part, so that the heat-exchanged air can be directly delivered to the user, and unlike Patent Document 1, the discharge port for discharging air into the indoor space is on one side of the exterior of the air conditioner, so that the modes of the discharged air cannot be formed in various ways.

[0006] In other words, in most cases, the air outlets in air conditioners open only toward the front of the unit. While some stand-alone air conditioners have outlets that open vertically along the left and right sides, these cannot generate airflow in conjunction with the outlets formed at the front.

[0007] In addition, Korean Patent No. 10-0679838, which is Patent Document 3, and Korean Patent No. 10-2201562, which is Patent Document 4, illustrate an air conditioning device installed on the ceiling, in which the air is inevitably discharged primarily toward the floor of the indoor space. In particular, since all of the discharge ports are formed to face the floor of the indoor space, there is a limit to controlling the direction of the discharged air using vanes.

[0008] The purpose of the present invention is to solve the conventional problems as described above, and to form discharge ports on the front surface of an air conditioning device and on the outer surface adjacent to the front surface and facing the floor of an indoor space, so as to discharge air of various airflows into the indoor space.

[0009] The purpose of the present invention is to enable air discharged from a plurality of discharge ports formed in an air conditioning device to cooperate with each other to form an air flow.

[0010] An object of the present invention is to use a vane assembly to control the direction of air discharged through a plurality of discharge ports formed in an air conditioning device.

[0011] An object of the present invention is to enable a first vane and a second vane in a vane assembly to cooperate with each other to guide air flow.

[0012] In order to achieve the above-mentioned purpose, the present invention provides a first discharge port formed on the front surface of the housing, and a second discharge port formed on the surface of the outer surface of the housing facing the floor of the indoor space.

[0013] The first outlet and the second outlet can be formed adjacently and side by side.

[0014] The air coming out of the first outlet can be configured to flow toward the upper part of the indoor space.

[0015] The air coming out of the second outlet can flow by combining with the air coming out of the first outlet.

[0016] In the present invention, the vane assembly guides the flow direction of air while the first vane and the second vane are simultaneously driven by a driving source.

[0017] The air conditioning device of the present invention may include a housing having an exterior appearance and an inlet for air from an indoor space to enter the interior, a first discharge port on a front side, and a second discharge port on an outer surface facing the floor of the indoor space, a driving fan installed inside the housing to generate air flow, a heat exchanger that performs heat exchange between air sucked from an indoor space and a working fluid inside the housing and is positioned between the inlet port and the driving fan, and a vane assembly having a first vane that opens and closes the second discharge port and guides the flow of air, and a second vane that guides the flow of air while operating in conjunction with the first vane.

[0018] The first discharge port may be formed on the lower front side of the housing, and the second discharge port may be formed to extend parallel to the first discharge port.

[0019] The second discharge port may be provided on an outer surface facing the floor of the indoor space while sharing the front and corner of the housing in which the first discharge port is formed.

[0020] A discharge unit may further be provided having an inclined surface having an incline toward the front upper portion of the first discharge port to guide air discharged from the first discharge port.

[0021] The above discharge unit may further be provided with a horizontal louver having a slope facing the front upper portion of the first discharge port to guide air discharged from the first discharge port.

[0022] A discharger may further be provided in which a path for flowing air to the first outlet and the second outlet is formed.

[0023] The above discharger is provided inside the first discharge port and the second discharge port, and the vane assembly can be installed within the flow path.

[0024] The above first vane can be positioned to protrude outward from the second outlet and inclined toward the floor to guide the flow of air.

[0025] The second vane can guide air by being positioned continuously with the first vane at the rear of the first vane or separated from the first vane when the second outlet of the first vane is open.

[0026] The second vane positioned at the rear of the first vane can be operated so that the rear end of the first vane is positioned higher than the front end of the second vane.

[0027] The above vane assembly may include a driving source, a driving link that rotates by receiving a driving force from the driving source and has a first vane driving unit and a second vane driving unit, a first vane that is connected to and driven by the first vane driving unit, and a second vane that is connected to and driven by the second vane driving unit.

[0028] The first vane may have one end connected to a discharger installed in the housing, and the other end of the first vane link may be connected to the first vane.

[0029] A rotation center shaft rotatably installed in the discharger may be provided at both ends of the second vane.

[0030] The second vane is provided with a connecting auxiliary part, and the rotational center axis of the connecting auxiliary part can be rotatably hung on the discharger.

[0031] The first outlet is always open, and the second outlet is opened and closed by the first vane. The airflow discharged from the first outlet is combined with the airflow discharged through the second outlet and guided by the first vane to flow in the indoor space.

[0032] The link body forms the skeleton of the above driving link, and on one outer surface of the link body, there is a driving source connection part connected to the driving shaft of the driving source, and on the other outer surface of the link body, the first vane driving part and the second vane driving part may be provided.

[0033] The above first vane driving unit can be connected to the first hole of the first link connecting unit formed at the end of the first vane.

[0034] The above second vane driving unit can be connected to a second vane link connected to a connecting hole of the second link connecting unit of the second vane.

[0035] The air conditioning device according to the present invention may have at least one of the following effects.

[0036] In the present invention, a first discharge port and a second discharge port are formed adjacent to each other on the front surface and the outer surface adjacent to the front surface among the outer surfaces of an air conditioning device, and the air discharged through these discharge ports cooperate to form an air flow. A vane assembly is used so that air can be discharged toward the upper front through the first discharge port formed on the front surface, and air can be discharged toward the lower part of the second discharge port and the forward direction of the first discharge port through the second discharge port formed on the outer surface adjacent to the front surface. Therefore, there is an effect in which various air flows can be formed through the first discharge port and the second discharge port.

[0037] In the present invention, air discharged through adjacent first and second outlets can cooperate to form an airflow. That is, the airflow discharged through the first outlet and the airflow discharged through the second outlet combine to form an airflow directed toward the upper front of the air conditioner, thereby preventing the airflow from being delivered directly to the user.

[0038] In the present invention, a vane assembly is used to control the direction of air discharged through the second outlet and the direction of air discharged through the first outlet. The first vane and the second vane of the vane assembly cooperate with each other to control the direction of air discharged through the second outlet, and when the second outlet is closed by the first vane, the second vane can guide the flow of air discharged through the first outlet. Accordingly, the air discharged from the air conditioning device can form various airflows.

[0039] In the present invention, the first vane and the second vane cooperate to guide the air flow discharged through the second outlet. That is, the first vane and the second vane are positioned sequentially to form the air flow discharged through the second outlet. In addition, the second vane can also rotate in conjunction with the rotational degree of the first vane to guide the air flow, thereby enabling air to be discharged in various modes.

[0058] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When designating components in each drawing, it should be noted that, where possible, identical components will be given the same reference numerals, even if they appear in different drawings. Furthermore, when describing embodiments of the present invention, if a detailed description of a related known structure or function is deemed to hinder understanding of the embodiments of the present invention, such detailed description will be omitted.

[0059] Figure 1 illustrates an air conditioning device according to an embodiment of the present invention. This specification presents a wall-mounted indoor unit as the air conditioning device. However, the present invention can also be applied to stand-alone or window-mounted units. These will be described in more detail below.

[0060] As illustrated in Fig. 1, the exterior of the air conditioning device is formed by a housing (10). When viewed from the front, the exterior of the air conditioning device including the housing (10) is close to a rectangular parallelepiped shape that extends long from side to side.

[0061] In addition to the housing (10), the chassis (20) described below may also constitute a portion of the exterior. In the illustrated embodiment, the bottom and back of the housing (10) are open, and the chassis (20) described below forms the bottom and back of the air conditioning device. Of course, the bottom and back of the housing (10) may not be open either. In other words, the housing (10) may form the entire exterior of the air conditioning device. In addition, the chassis (20) located in the open portion of the housing (10) and constituting the exterior in this embodiment may also be viewed as a portion of the housing (10).

[0062] The housing (10) may have a rectangular prism shape overall, with corners that may be curved. The housing (10) has a front surface (11), which is an outer surface facing the front of the air conditioning device, and side surfaces (12) on both sides of the front surface (11). The front surface (11) and the side surfaces (12) may be adjacent to each other and be approximately perpendicular to each other. The outer surface of the housing (10) facing the upper portion of the air conditioning device is the upper surface (13). The upper surface (13) may have a slight slope overall toward the front.

[0063] There is a bottom surface (14), which is the lower outer surface of the air conditioning device shown in the drawing. As described above, the bottom surface (14) may be formed by the housing (10) or the chassis (20). In the illustrated embodiment, the chassis (20) forms the bottom surface (14).

[0064] An intake port (16) is formed on the upper surface (13) of the housing (10). The intake port (16) is a portion through which air within a space for air conditioning is sucked into the housing (10). As can be seen in Fig. 2, the intake port (16) is mostly perforated and has a lattice structure. A mesh-like structure may be installed in the perforated portion of the lattice structure to allow free air flow.

[0065] A first discharge port (17) is formed on the front surface (11) of the housing (10). The first discharge port (17) may be formed at a relatively lower portion of the front surface (11) of the housing (10). That is, the first discharge port (17) may be formed at a position adjacent to the bottom surface (14) of the housing (10). In the illustrated embodiment, the first discharge port (17) is formed to extend longwise from side to side when viewed from the front of the housing (10). The first discharge port (17) is open toward the front of the housing (10).

[0066] A second discharge port (18) is formed on the bottom surface (14) of the housing (10). The second discharge port (18) is open toward the floor of the space where the air conditioning device is installed. That is, an imaginary line in the opening direction of the first discharge port (17) and an imaginary line in the opening direction of the second discharge port (18) can be nearly orthogonal.

[0067] The second discharge port (18) is also located relatively forward from the bottom surface (14). That is, the second discharge port (18) is formed adjacent to the first discharge port (17). In the illustrated embodiment, the first discharge port (17) and the second discharge port (18) are formed to extend parallel to each other with the corners of the outer surfaces adjacent to each other in the middle. Of course, as another example, the corner where the front surface (11) and the bottom surface (14) are connected may be curved, and the first discharge port (17) and the second discharge port (18) may be formed adjacent to each other.

[0068] In the illustrated embodiment, a wall-mounted air conditioner is presented, so the second outlet (18) is formed on the bottom surface (14) of the housing (10). However, when the present invention is applied to, for example, a stand-alone air conditioner, the front surface of the stand-alone air conditioner may protrude relatively compared to other parts of the housing. The second outlet (18) may be formed on an outer surface facing the floor of the space for air conditioning while being perpendicular to the front surface of this protruding portion. In this case, the height from the floor where the first outlet (17) and the second outlet (18) are located may be higher than the height of a typical user. This configuration in which the first outlet (17) and the second outlet (18) are arranged is the same even in the case of a window-type air conditioner.

[0069] The chassis (20) is installed inside the housing (10). In the illustrated embodiment, the chassis (20) forms the rear and bottom surfaces of the exterior of the air conditioning device. A driving fan (30), a control box (32), a heat exchanger (40), a discharger (60), etc., which will be described below, can be installed in the chassis (20). The chassis (20) is installed inside the housing (10) and serves as a skeleton.

[0070] A rear guide (22) is formed in the above chassis (20) to guide air flowing inside the housing (10). The space formed by the rear guide (22) is called a flow path forming space (24). A driving fan (30) is installed in the flow path forming space (24). Air can flow between the outer surface of the driving fan (30) and the inner surface of the rear guide (22). The control box (32) can control the operation of the air conditioning device. The control box (32) can be mounted on one side of the chassis (20).

[0071] A heat exchanger (40) may be installed within the space formed by the housing (10) and the chassis (20). The heat exchanger (40) is a part that performs heat exchange between the working fluid and air. The heat exchanger (40) is installed in the housing (10) and the chassis (20) so as to surround the driving fan (30). Heat exchange occurs as air passes through the heat exchanger (40).

[0072] Left and right louver assemblies (50) may be installed in the area where air flows between the above-mentioned driving fan (30) and the rear guide (22). The left and right louver assemblies (50) are not necessarily used. The left and right louver assemblies (50) serve to control the direction of air flowing in the flow path forming space (24).

[0073] A discharger (60) may be positioned at the tip of the rear guide (22) of the chassis (20). The discharger (60) has a passage (60') through which air passing through the passage forming space (24) passes. A discharge unit (62) and a vane assembly (70) to be described below may be installed in the discharger (60). For this purpose, a first hanging piece (61) is provided in the passage (60'). The first hanging piece (61) is a portion on which one side of the first vane link (720) to be described below is hung. A second hanging piece (61') is provided in the passage (60'). A rotation center shaft (753') of a connection auxiliary part (753) of a second vane (750) to be described below may be rotatably hung on the second hanging piece (61'). This configuration is well illustrated in Fig. 5.

[0074] In the above discharger (60), a discharge unit (62) may be installed between the first discharge ports (17). The configuration of the discharge unit (62) is well illustrated in FIGS. 5 and 8. The discharge unit (62) may guide air to be discharged through the first discharge port (17). A discharge path (64) may be formed by penetrating the discharge unit (62) forward and backward, and an inclined surface (66) may be formed on the bottom of the discharge path (64). The discharge unit (62) may guide the direction of air discharged through the first discharge port (17) by the inclined surface (66). As a result, air discharged through the first discharge port (17) may be guided to the front upper portion of the housing (10). A horizontal vane (67) may be provided within the discharge path (64). The above-mentioned cross-section (67) may have the same angle as the above-mentioned inclined surface (66). That is, the angle of the cross-section (67) may be formed so as to guide air toward the upper front.

[0075] Next, the configuration of the vane assembly (70) that guides the air discharged through the first discharge port (17) and the second discharge port (18) inside the housing (10) will be described. The vane assembly (70) has a first vane (730) and a second vane (750), and the first vane (730) opens and closes the second discharge port (18) and controls the direction of the air discharged through the second discharge port (18). The second vane (750) operates together with the first vane (730), and can selectively perform the role of guiding the air flowing inside the housing (10) to the first discharge port (17) and the role of guiding the air discharged through the second discharge port (18) in cooperation with the first vane (730).

[0076] Figures 3 to 7 illustrate the configuration of a vane assembly (70). The vane assembly (70) includes a driving source (700) that provides driving force for the operation of the first vane (730) and the second vane (750). A step motor may be used as the driving source (700).

[0077] A drive link (710) is connected to the drive shaft of the above-described driving source (700). The configuration of the drive link (710) is well illustrated in FIG. 9. The drive link (710) can be rotated around the drive shaft by the driving force of the drive source (700). In the present embodiment, two drive sources (700) can be used, one each at both ends of the first vane (730) and the second vane (750). Accordingly, two sets of the drive links (710) and their related components can also be used. Of course, one drive source (700) may be used depending on design conditions such as the left and right lengths of the first vane (730) and the second vane (750).

[0078] The skeleton of the above-described driving link (710) is formed by a link body (711). The link body (711) is shaped like a disk in the illustrated embodiment. The link body (711) may have various shapes other than a disk shape, as long as it does not interfere with other surrounding components.

[0079] One side of the above link body (711) may have a drive source connection part (712). The drive shaft of the drive source (700) may be inserted into and connected to the drive source connection part (712). The drive source connection part (712) may be formed at the rotation center of the link body (711).

[0080] The link body (711) has a first vane driving part (713). The first vane driving part (713) may be integrally formed on the opposite surface where the drive source connecting part (712) is located. The first vane driving part (713) has a cantilever shape extended by a predetermined length. The first vane driving part (713) is connected to the first vane (730) to transmit driving force. The first vane driving part (713) is bent to have a predetermined radius of curvature in the illustrated embodiment. A connecting pin (713') is provided at a free end of the first vane driving part (713). The connecting pin (713') may have a snap-fastening structure. The connecting pin (713') has an overall cylindrical shape, but may be formed of a plurality of elastic pieces. A hook (not provided with a drawing symbol) is provided at the free end of each elastic piece.

[0081] The link body (711) has a second vane driving part (714). The second vane driving part (714) may be formed to protrude from one surface of the link body (711) on which the first vane driving part (713) is formed. The second vane driving part (714) is connected to the second vane (750) to transmit driving force. A connecting pin (715) may be formed on the second vane driving part (714). The connecting pin (714) may have a cylindrical shape. The connecting pin (714) may have the same structure as the connecting pin (713') of the first vane driving part (713). A hooking jaw (716) is formed on the connecting pin (714). The above-mentioned hanging jaw (716) serves to prevent the above-mentioned connecting pin (715) from coming off from the second vane (750) side.

[0082] The above drive link (710) can drive the first vane (730) with the first vane drive unit (713) while rotating with the driving force of the drive source (700) and simultaneously drive the second vane (750) with the second vane drive unit (714). That is, the drive link (710) drives the first vane (730) and the second vane (750) simultaneously with the driving force of the drive source (700).

[0083] The first vane link (720) can be rotatably connected at one end to the discharger (60). The other end of the first vane link (720) can be rotatably connected to the first vane (730). The first vane link (720) allows the first vane (730) to be connected to and supported by the discharger (60). The configuration of the first vane link (720) is well illustrated in Fig. 10. The skeleton of the first vane link (720) is formed by the first link body (721). The first link body (721) is bar-shaped. There are connecting pins (723, 723') at both ends of the first link body (721). The configuration of the above connecting pin (723, 723') is the same as the connecting pin (713') of the first vane driving part (713) of the above driving link (710). Of course, the configuration of the above connecting pin (723, 723') may be different from the above connecting pin (713'). The above connecting pin (723, 723') may have various types of snap-on structures, or may have the same structure as the connecting pin (715) of the above second vane driving part (714).

[0084] The above first vane link (720) is used in multiple numbers in this embodiment. The number of first vane links (720) can be determined depending on the left and right lengths of the first vane (730). In this embodiment, four first vane links (720) are used.

[0085] In this embodiment, the connecting pins (723, 723') of the first vane link (720) protrude in opposite directions from both ends of the first link body (721). However, depending on design conditions, they may be formed to protrude from the same side of the first link body (721).

[0086] Among the connecting pins (723, 723') of the first vane link (720), the connecting pin (723') is rotatably connected to the discharger (60). As can be seen in Fig. 5, the connecting pin (723') is rotatably installed on one side of the first hook piece (61) or the discharger (60). The other connecting pin (723) is rotatably installed on the link connection auxiliary part (733) of the first vane (730).

[0087] The structure of the first vane (730) is well illustrated in Fig. 11. The first vane (730) has a first vane body (731) that is roughly plate-shaped and forms a skeleton. The first vane body (731) has a rectangular plate shape. The first vane body (731) may have an area capable of shielding the second discharge port (18). That is, the first vane (730) closes the second discharge port (18) so that air is not discharged through the second discharge port (18) in a specific mode.

[0088] There is a first link connecting portion (732) on both ends of the inner surface of the first vane body (731). The first link connecting portion (732) can be perpendicular to the first vane body (731). The first link connecting portion (732) has an approximately plate shape. A first hole (732') and a second hole (732") are formed in the first link connecting portion (732). A connecting pin (713') of the first vane driving portion (713) of the driving link (710) is installed by penetrating through the first hole (732'). A connecting pin (723) of the first vane link (720) is rotatably inserted into the second hole (732").

[0089] In this embodiment, the first vane (730) is made rotatable to the discharger (60) using four first vane links (720). The first vane (730) has two link connection auxiliary parts (733) so that two of the four first vane links (720) are hooked. As can be seen in Fig. 11, the remaining first vane links (720) are inserted into the second holes (732") of the two link connection auxiliary parts (733) and the two first link connection parts (732) and are hooked.

[0090] The second vane link (740) connects the second vane (750) to the drive link (710) and functions to transmit the driving force of the drive source (700) to the second vane (750). The configuration of the second vane link (740) is well illustrated in Fig. 12. The second link body (741) forms the skeleton of the second vane link (740). The second link body (741) has a flat and elongated plate shape. A connecting pin (741') is formed at one end of the second link body (741). The connecting pin (741') is connected to the second vane (750) so as to be relatively rotatably connected. A hooking jaw (741") protrudes from a free end of the connecting pin (741'). The hooking jaw (741") protrudes orthogonally to the extension direction of the connecting pin (741').

[0091] A connecting hole (742') is formed at the opposite end of the second link body (741) having the connecting pin (741'). The connecting hole (742') is used for connection with the driving link (710). A through hole (742") is formed at one side of the connecting hole (742'). The through hole (742") and the connecting hole (742') are connected. The through hole (742") is a portion into which a connecting pin (715) of a second vane driving part (714) of the driving link (710) is inserted so as to be relatively rotatable. A hook (716) of the connecting pin (715) passes through the through hole (742") and is movably hung on the opposite side of the second link body (741).

[0092] The second vane (750) is positioned within the flow path of the discharger (60) and serves to guide passing air. As can be seen in Fig. 13, the second vane (750) has a second vane body (751) having a long rectangular shape forming a skeleton. The second vane body (751) may have approximately the same left-right length as the first vane body (731). The front-to-back width of the second vane body (751) is relatively narrower than the front-to-back width of the first vane body (731).

[0093] At both ends of the second vane body (751), there are second link connecting portions (752). The second link connecting portions (752) are formed to protrude in one direction at both ends of the second vane body (751). The connecting pin (741') of the second vane link (740) is connected to the second link connecting portion (752). For this purpose, a connecting hole (752') is formed in the second link connecting portion (752). The connecting pin (741') of the second vane link (740) is rotatably inserted into the connecting hole (752'). A hooking jaw hole (752") is formed in the connecting hole (752'). The hooking jaw hole (752") is communicated with the connecting hole (752'). The hook jaw (741") of the second vane link (740) passes through the hook jaw opening (752") and is movably hung on the opposite side of the second link connecting portion (752).

[0094] In the second vane body (751), a connecting auxiliary part (753) is provided at a certain interval between the second link connecting parts (752) at both ends. The connecting auxiliary part (753) is provided with a rotational center axis (753'). The rotational center axis (753') is rotatably hung on the second hanging piece (61') of the discharger (60).

[0095] There is a rotation center axis (755) at each end of the second vane body (751). As schematically shown in Fig. 5, the rotation center axis (755) is rotatably installed on one side of the inner surface of the flow path (60') of the discharger (60).

[0096] In the illustrated embodiment, the first vane (730) and the second vane (750) have a left-right length longer than their front-back width. Therefore, the drive source (700) and the drive link (710) are provided at both ends of the first vane (730) and the second vane (750) so that the first vane (730) and the second vane (750) operate uniformly over the entire left-right length. Accordingly, components that are linked to the drive link (710) are provided at both ends of the first vane (730) and the second vane (750). However, if the left-right lengths of the first vane (730) and the second vane (750) are short, the drive source (700), the drive link (710), etc. may be provided on only one end. This also applies to the first vein link (720), the second vein link (740), and the connecting auxiliary part (753).

[0097] The operation of the air conditioning device according to the present invention having the configuration described above will be described below.

[0098] First, as illustrated in (a) of FIG. 14, when the second outlet (18) is blocked by the first vane (730), air can only be discharged through the first outlet (17). At this time, the second vane (750) serves to guide air to the first outlet (17). When air is discharged through the first outlet (17), the air is guided by the inclined surface (66) and the horizontal vane (67) and discharged toward the upper front of the first outlet (17). Therefore, the heat-exchanged air is discharged to a relatively high position in the space for air conditioning, that is, a position higher than the user's head, so that the heat-exchanged air does not directly reach the user. In this way, the heat-exchanged air is guided and discharged only through the first outlet (17) as illustrated in FIG. 15.

[0099] When air is discharged through the second discharge port (18), the first vane (730) operates to open the second discharge port (18). In addition, the amount of air discharged through the second discharge port (18) varies depending on the degree to which the first vane (730) opens the second discharge port (18), and the direction of the air discharged through the second discharge port (18) varies depending on the angle at which the first vane (730) is installed at the inlet of the second discharge port (18). An example of a state in which the second discharge port (18) is open is illustrated in (b) of Fig. 14.

[0100] In this way, in order for the first vane (730) to open the second outlet (18) so that the heat-exchanged air can be discharged through the first outlet (17) and the second outlet (18), the first vane (730) and the second vane (750) must be operated.

[0101] The second vane (750) is driven simultaneously with the first vane (730) using a single drive link (710). Therefore, the angle of the second vane (750) also changes as the first vane (730) operates.

[0102] In order to drive the first vane (730) and the second vane (750), the drive source (700) of the vane assembly (70) operates. When the drive source (700) is driven and the drive shaft rotates, the drive link (710) rotates. The rotation of the drive link (710) causes the first vane drive unit (713) and the second vane drive unit (714) to operate simultaneously. The first vane (730) is operated by the first vane drive unit (713). The second vane link (740) operates the second vane (750) by the second vane drive unit (714).

[0103] Looking at this in more detail, when the driving link (710) is rotated in the direction of arrow A by the driving source (700) based on (a) of FIG. 14, the first vane driving part (713) is operated so that the connecting pin (713") of the first vane driving part (713) moves in the direction of arrow A'. Accordingly, the first vane (730) rotates, and the first vane (730) moves toward the lower left based on the drawing. At this time, the movement trajectory of the first vane (730) is created by the first vane link (720), and the first vane (730) does not protrude more than a certain amount, and the first vane (730) rotates around the part where the first vane link (720) is connected to the discharger (60).

[0104] Meanwhile, the second vane link (740) connected to the second vane driving part (714) of the driving link (710) drives the second vane (750), and the second vane (750) moves along a circular path with the rotation center axis (755) as the center. Accordingly, as shown in (a) of FIG. 14, the second vane link (740) rotates in the direction of arrow B, and the second vane (750) moves along a circular path in the direction of arrow B' with the rotation center axis (755) as the center.

[0105] In this way, when the driving link (710) rotates at a predetermined angle, the second discharge port (18) is opened as in the state shown in (b) of Fig. 14, and the heat-exchanged air is discharged through the second discharge port (18). At this time, the direction in which the heat-exchanged air is transferred is determined according to the angle at which the first vane (730) is inclined downwardly forward based on the drawing.

[0106] And, in Fig. 16, it is illustrated that the first vane (730) opens the second outlet (18) so that the heat-exchanged air is discharged simultaneously through the first outlet (17) and the second outlet (18). As can be seen here, the airflow discharged through the first outlet (17) and the airflow discharged through the second outlet (18) can be seen to merge with each other at the front of the housing (10). This is because the speed of the air discharged through the second outlet (18) guided by the first vane (730) is relatively faster than the speed of the air discharged through the first outlet (17), and thus the two airflows, which have a pressure difference due to Bernoulli's principle, merge at the front of the housing (10).

[0107] This condition can be clearly confirmed in the graph shown in Fig. 17. That is, it can be seen that the airflow discharged from the second discharge port (18) moves upward along the vane extension line and flows away from the imaginary extension line of the first vane (730).

[0108] In FIG. 18 to FIG. 23, operation modes that vary depending on the angles of the first vane (730) and the second vane (750) are illustrated. This will be described based on the first vane (730). The basic modes of the first vane (730) include a closed mode (air discharged through the first discharge port (17)), a cooling mode, and a heating mode. Here, the basic state of the cooling mode is illustrated in FIG. 18, and the basic state of the heating mode is illustrated in FIG. 23.

[0109] In cooling mode, as illustrated in FIG. 18, the vane angle (A) formed by the first vane (730) is set to be 0° to 35°. In addition, the height difference (B) between the first vane (730) and the second vane (750) is set to be 0 mm or more. Based on the figure illustrated in FIG. 18, the vane angle (A) of the first vane (730) is 20° and the height difference (B) is 1.5 mm.

[0110] In the basic state of the heating mode illustrated in Fig. 23, the first vane (730) is rotated so that the vane angle (A) is between 50° and 90°. The second vane (750) is rotated to a position where it does not touch the rear guide (22) so that the direction of the rear airflow is directed downward as much as possible.

[0111] A total of six modes, including the basic states of the cooling mode and heating mode, are illustrated in FIGS. 18 to 23, where the angles of the first vane (730) and the second vane (750) are sequentially changed. When operating in one of these six modes (including the basic states of the cooling mode and the heating mode), air is discharged simultaneously from the first discharge port (17) and the second discharge port (18), thereby enabling cooling and heating. It can be seen that as one moves from FIG. 18 to FIG. 23, the inclination of the first vane (730) is adjusted to face the front lower portion of the air conditioner and then gradually face further downward.

[0112] The angle of the vanes may be set to any one of the six modes described above and air conditioning may be performed, but air conditioning may also be performed in a swing mode in which the angle of the vanes is repeatedly changed within a predetermined range between the cooling mode and the heating mode.

[0113] Although all components constituting embodiments of the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the present invention, all components may be selectively combined and operated in one or more combinations.
