Abstract
Description
Technical Field
[0001] This invention relates to an air conditioning device. Background Technology
[0002] An air conditioning unit is a device used to maintain the air in an indoor space at an optimal state for a specific purpose. For example, in summer, air conditioning units typically function to relatively lower the indoor air temperature by expelling heat from the room to the outside. Conversely, in winter, they relatively raise the temperature of the air exhausted from the air conditioning unit to make the indoor temperature relatively higher than the outdoor temperature.
[0003] Air conditioning units supply heat-exchanged air to indoor spaces requiring air conditioning, and the location of users within those spaces must be taken into account when appropriately exhausting the air. For example, the direction of air exhaust may need to be adjusted to prevent air from being directly delivered to users.
[0004] In particular, air conditioning units that are set adjacent to or flush against a wall of the interior space, or installed on a wall, such as freestanding, wall-mounted, and window-type air conditioning units, often directly deliver air to the user. For example, Korean Utility Model No. 20-0146110, which is patent document 1, shows an indoor unit of a wall-mounted air conditioning unit in which heat-exchanged air is directly delivered to the user by discharging air at a downward angle through an air outlet.
[0005] In addition, in Korean Patent No. 10-0234964, which is patent document 2, since it is also configured to discharge air to the lower front part of the air conditioning device, it can directly deliver the heat-exchanged air to the user. In addition, as in patent document 1, since the air outlet for discharging air into the indoor space is located on one side of the exterior of the air conditioning device, the air discharge pattern cannot be varied.
[0006] In other words, in most cases, the air outlet in an air conditioning unit only opens to the front of the unit. Of course, in a vertical air conditioning unit, although there are air outlets opening up and down along the left and right sides, in this case, they cannot work together with the air outlet formed on the front to create airflow.
[0007] Furthermore, Korean Patent No. 10-0679838 (Patent Document 3) and Korean Patent No. 10-2201562 (Patent Document 4) disclose an air conditioning device installed on the ceiling, in which air can only be exhausted to the floor of the indoor space. In particular, since multiple air outlets are formed facing the floor of the indoor space, the direction of the exhaust air controlled by the blades is restricted. Summary of the Invention
[0008] The problem that the invention aims to solve
[0009] The purpose of this invention is to solve the existing problems as described above by forming air outlets on the front of the air conditioning device and on the outer surface of the floor adjacent to the front and facing the indoor space to discharge various airflows into the indoor space.

[0021] The second air outlet can share an edge with the front of the cover where the first air outlet is formed and is located on the outer surface of the cover facing the indoor space.
[0022] An exhaust unit may also be provided, which has an inclined surface that slopes upward toward the front of the first air outlet to guide the air discharged from the first air outlet.
[0023] The exhaust unit may also be provided with a horizontal louver that is tilted upwards and forwards of the first air outlet to guide the air discharged from the first air outlet.
[0024] A discharger may also be provided, which forms a flow path that directs air toward the first air outlet and the second air outlet.
[0025] The air guide can be disposed inside the first air outlet and the second air outlet, and the blade assembly can be disposed within the flow path.
[0026] The first blade can be configured to protrude outward from the second air outlet and tilt towards the ground to guide the flow of air.
[0027] With the first blade opening the second air outlet, the second blade can be continuously arranged behind the first blade or separated from the first blade to guide air.
[0028] The second blade, located behind the first blade, can be actuated so that the rear end of the first blade is positioned above the front end of the second blade.
[0029] The blade assembly may include: a drive source; a drive link that receives the driving force from the drive source to rotate, and is provided with a first blade drive part and a second blade drive part; a first blade connected to the first blade drive part to be driven; and a second blade connected to the second blade drive part to be driven.

[0037] Invention Effects
[0038] The air conditioning device according to the present invention can have at least one of the following effects.
[0039] In this invention, a first air outlet and a second air outlet are formed adjacent to each other on the outer surface of the air conditioning device, on the front and the outer surface adjacent to the front. Air discharged through these plurality of air outlets cooperates to form an airflow. Air can be discharged forward and upward through the first air outlet formed on the front, and a blade assembly is used to allow air to be discharged downward and forward of the second air outlet formed on the outer surface adjacent to the front. Therefore, it has the effect of being able to form various airflows through the first and second air outlets.
[0040] In this invention, the air discharged through the first and second air outlets, which are adjacent to each other, can cooperate to form an airflow. That is, the airflow discharged through the first air outlet and the airflow discharged through the second air outlet merge, thereby forming an airflow that is directed towards the upper front of the air conditioning device as a whole, so as to prevent the airflow from being directly transmitted to the user.
[0041] In this invention, a blade assembly is used to adjust the direction of air discharged through the second air outlet and the direction of air discharged through the first air outlet. The first and second blades of the blade assembly cooperate to control the direction of air discharged through the second air outlet, and when the second air outlet is closed by the first blade, the second blade guides the flow of air discharged through the first air outlet. Therefore, the air discharged from the air conditioning device can form various airflow patterns.
[0042] In this invention, the first blade and the second blade cooperate to guide the flow of air discharged through the second air outlet. That is, the first blade and the second blade are arranged sequentially to create a flow of air discharged through the second air outlet. In addition, the second blade can also rotate in conjunction with the rotation of the first blade to guide the air flow, thus enabling air to be discharged in various modes.

[0061] Hereinafter, some embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that when adding reference numerals to the constituent elements of the various drawings, even if the same constituent element is shown in different drawings, the same reference numerals should be used as much as possible. Furthermore, when describing embodiments of the present invention, detailed descriptions of related well-known structures or functions will be omitted if it is determined that such detailed descriptions may hinder understanding of the embodiments of the present invention.
[0062] Figure 1 An air conditioning device according to an embodiment of the present invention is shown in this specification. In this specification, a wall-mounted indoor unit is proposed as the air conditioning device. However, the present invention can also be applied to floor-standing or window-mounted units. This will be described in more detail below.
[0063] like Figure 1As shown, the cover 10 forms the appearance of an air conditioning device. When viewed from the front, the appearance of the air conditioning device, including the cover 10, is approximately a cuboid shape extending long from left to right.
[0064] In addition to the cover 10, the chassis 20 described below can also constitute part of the appearance. In the illustrated embodiment, the bottom and back surfaces of the cover 10 are open, and the chassis 20 described below forms the bottom and back surfaces of the air conditioning device. Of course, the bottom and back surfaces of the cover 10 can also be closed. That is, the cover 10 can also form the entire appearance of the air conditioning device. In addition, in this embodiment, the chassis 20, which is disposed in the open portion of the cover 10 and constitutes the appearance, can also be regarded as part of the cover 10.
[0065] The cover 10 is generally rectangular in shape, and its edges can be curved. The cover 10 has a front surface 11 facing the air conditioning device, and side surfaces 12 on both sides of the front surface 11. The front surface 11 and side surfaces 12 can be adjacent to each other and approximately orthogonal. The outer surface of the cover 10 facing the upper part of the air conditioning device is a top surface 13. The top surface 13 can be slightly inclined forward.
[0066] A bottom surface 14, as shown in the accompanying drawings, serves as the outer surface of the lower part of the air conditioning device. As described above, the bottom surface 14 can be formed by the cover 10 or by the bottom shell 20. In the illustrated embodiment, the bottom surface 14 is formed by the bottom shell 20.
[0067] An intake port 16 is formed on the top surface 13 of the enclosure 10. The intake port 16 is the portion that draws in air existing within the space for air conditioning into the interior of the enclosure 10. For example, it can be... Figure 2 As observed, most of the intake 16 is penetrated and has a mesh structure. Because the penetrations in the mesh structure are configured like a mesh, airflow is also allowed to be free.
[0068] A first air outlet 17 is formed on the front surface 11 of the cover 10. The first air outlet 17 may be formed on the lower part of the front surface 11 of the cover 10. That is, the first air outlet 17 may be formed adjacent to the bottom surface 14 of the cover 10. In the illustrated embodiment, when viewed from the front of the cover 10, the first air outlet 17 extends elongated left and right. The first air outlet 17 opens towards the front of the cover 10.
[0069] A second air outlet 18 is formed on the bottom surface 14 of the enclosure 10. The second air outlet 18 opens toward the ground of the space where the air conditioning device is installed. That is, the imaginary line of the opening direction of the first air outlet 17 and the imaginary line of the opening direction of the second air outlet 18 can be almost orthogonal.
[0070] The second air outlet 18 is also located at a relatively forward position on the bottom surface 14. That is, the second air outlet 18 is formed adjacent to the first air outlet 17. In the illustrated embodiment, the first air outlet 17 and the second air outlet 18 extend side by side with the edges of their adjacent outer surfaces as the center. Of course, as another example, the edge connecting the front surface 11 and the bottom surface 14 can be a curved surface, and the first air outlet 17 and the second air outlet 18 can also be formed adjacent to each other.
[0071] Although in the illustrated embodiment, since a wall-mounted air conditioning unit is proposed, the second air outlet 18 is formed on the bottom surface 14 of the housing 10, for example, in the case where the invention is applicable to a vertical unit, the front of the vertical air conditioning unit can protrude relatively compared to other parts of the housing. The second air outlet 18 can be formed on the outer surface of the floor facing the space used for air conditioning, orthogonal to the front of this protruding portion. In this case, the height of the first air outlet 17 and the second air outlet 18 above the ground can be higher than the height of an average user. As described above, the configuration with the first air outlet 17 and the second air outlet 18 is also applicable to the case of a window-type air conditioning unit.
[0072] The bottom shell 20 is disposed inside the cover 10. In the illustrated embodiment, the bottom shell 20 forms the back and bottom surfaces of the air conditioning device. The bottom shell 20 may house a drive fan 30, a control box 32, a heat exchanger 40, and an air guide 60, which will be described below. The bottom shell 20 functions as a frame inside the cover 10.
[0073] A rear guide 22 is formed on the bottom shell 20, thus guiding the airflow inside the housing 10. The space formed by the rear guide 22 is named the flow path forming space 24. A drive fan 30 is provided in the flow path forming space 24. Air can flow between the outer surface of the drive fan 30 and the inner surface of the rear guide 22. A control box 32 controls the operation of the air conditioning device. The control box 32 can be installed on one side of the bottom shell 20.
[0074] A heat exchanger 40 may be disposed within the space formed by the housing 10 and the bottom shell 20. The heat exchanger 40 is the part that performs heat exchange between the working fluid and the air. The heat exchanger 40 is disposed in the housing 10 and the bottom shell 20 in a manner that surrounds the drive fan 30. Heat exchange occurs as air passes through the heat exchanger 40.
[0075] A left and right louver assembly 50 may be provided in the airflow area between the drive fan 30 and the rear guide member 22. The use of the left and right louver assembly 50 is not mandatory. The left and right louver assembly 50 serves to control the direction of airflow in the flow path forming space 24.
[0076] An air guide 60 may be disposed at the front end of the rear guide 22 of the bottom shell 20. The air guide 60 is provided with a flow path 60' through which air flowing through the flow path forming space 24 passes. The air guide 60 may be provided with an exhaust unit 62 and a blade assembly 70, which will be described below. For this purpose, a first hanging piece 61 is provided within the flow path 60'. The first hanging piece 61 is a portion for attaching to one side of the first blade connecting rod 720, which will be described below. A second hanging piece 61' is provided within the flow path 60'. The second hanging piece 61' can be rotatably attached to the rotation center shaft 753' on the connection auxiliary portion 753 of the second blade 750, which will be described below. The configuration described above is shown in detail in the diagram. Figure 5 .
[0077] In the air guide 60, a discharge unit 62 may be provided between the first air outlets 17. The configuration of the discharge unit 62 is shown in detail in [the diagram]. Figure 5 and Figure 8 The discharge unit 62 guides air towards the first air outlet 17. The discharge unit 62 can be extended longitudinally to form a discharge flow path 64, and an inclined surface 66 can be formed at the bottom of the discharge flow path 64. The discharge unit 62 can use the inclined surface 66 to guide the air out through the first air outlet 17. Thus, the air discharged through the first air outlet 17 can be guided to the upper front of the cover 10. A transverse blade 67 can be provided within the discharge flow path 64. The transverse blade 67 can have the same angle as the inclined surface 66. That is, the angle of the transverse blade 67 can be configured to guide the air forward and upward.
[0078] Next, the configuration of the blade assembly 70 will be described. The blade assembly 70 guides the air discharged through the first air outlet 17 and the second air outlet 18 inside the housing 10. The blade assembly 70 is provided with a first blade 730 and a second blade 750. The first blade 730 opens and closes the second air outlet 18 and controls the direction of air discharge through the second air outlet 18. The second blade 750 operates together with the first blade 730 and can selectively guide the air flowing inside the housing 10 to the first air outlet 17 and cooperate with the first blade 730 to guide the air to be discharged through the second air outlet 18.
[0079] exist Figures 3 to 7 The structure of the blade assembly 70 is shown in the figure. A drive source 700 is provided in the blade assembly 700, which provides driving force for the movement of the first blade 730 and the second blade 750. A stepper motor can be used as the drive source 700.
[0080] A drive linkage 710 can be connected to the drive shaft of the drive source 700. The configuration of the drive linkage 710 is shown in detail in [the diagram]. Figure 9 The drive link 710 can rotate around the drive shaft using the driving force of the drive source 700. In this embodiment, one drive source 700 can be used at each end of the first blade 730 and the second blade 750, for a total of two. Therefore, two sets of the drive link 710 and its related components can also be used. Of course, depending on the design conditions such as the left-right length of the first blade 730 and the second blade 750, a single drive source 700 can also be used.
[0081] The link body 711 forms the skeleton of the drive link 710. In the illustrated embodiment, the link body 711 is disc-shaped. However, it can be any shape other than a disc if it does not interfere with other surrounding components.
[0082] A drive source connection portion 712 may be provided on one side of the connecting rod body 711. The drive shaft of the drive source 700 can be inserted into and coupled to the drive source connection portion 712. The drive source connection portion 712 may be formed at the rotation center of the connecting rod body 711.
[0083] A first blade drive portion 713 is provided on the connecting rod body 711. The first blade drive portion 713 may be integrally formed on the opposite side of the surface where the drive source connection portion 712 is located. The first blade drive portion 713 is a cantilever beam shape extending a predetermined length. The first blade drive portion 713 is connected to the first blade 730 and transmits driving force. In the illustrated embodiment, the first blade drive portion 713 is bent to have a predetermined radius of curvature. A connecting pin 713' is provided at the free end of the first blade drive portion 713. The connecting pin 713' may have a snap-fit fastening structure. Although the connecting pin 713' is generally cylindrical, it may be made of a plurality of elastic plates. A hanging flange (not shown in the figure) is provided at the free end of each elastic plate.
[0084] A second blade drive portion 714 is provided in the connecting rod body 711. The second blade drive portion 714 may be formed protruding from the side of the connecting rod body 711 where the first blade drive portion 713 is formed. The second blade drive portion 714 is connected to the second blade 750 to transmit driving force. A connecting pin 715 may be formed in the second blade drive portion 714. The connecting pin 714 may be cylindrical. The connecting pin 714 may also have a structure similar to the connecting pin 713' of the first blade drive portion 713. A hanging flange 716 is formed in the connecting pin 714. The hanging flange 716 serves to prevent the connecting pin 715 from falling off the second blade 750 side.
[0085] The drive link 710 can rotate under the driving force of the drive source 700 and drive the first blade 730 with the first blade drive part 713, while simultaneously driving the second blade 750 with the second blade drive part 714. That is, the drive link 710 drives the first blade 730 and the second blade 750 simultaneously with the driving force of the drive source 700.
[0086] One end of the first blade connecting rod 720 is rotatably connected to the air guide 60. The other end of the first blade connecting rod 720 is rotatably connected to the first blade 730. The first blade connecting rod 720 is used to connect and support the first blade 730 to the air guide 60. The structure of the first blade connecting rod 720 is shown in detail in [the diagram]. Figure 10The first connecting rod body 721 forms the skeleton of the first blade connecting rod 720. The first connecting rod body 721 is rod-shaped. Connecting pins 723 and 723' are provided at both ends of the first connecting rod body 721. The configuration of the connecting pins 723 and 723' is the same as that of the connecting pin 713' provided in the first blade driving part 713 of the driving connecting rod 710. Of course, the configuration of the connecting pins 723 and 723' can also be different from that of the connecting pin 713'. The connecting pins 723 and 723' can be various forms of snap-fit structures, or they can be the same structure as the connecting pin 715 of the second blade driving part 714.
[0087] In this embodiment, a plurality of first blade connecting rods 720 are used. The number of first blade connecting rods 720 can be determined based on the left-right length of the first blade 730. In this embodiment, four first blade connecting rods 720 are used.
[0088] In this embodiment, the connecting pins 723 and 723' of the first blade connecting rod 720 can protrude from both ends of the first connecting rod body 721 in opposite directions. However, depending on the design conditions, they can also be formed to protrude from the same side of the first connecting rod body 721.
[0089] In the connecting pins 723 and 723' of the first blade connecting rod 720, the connecting pin 723' is rotatably connected to the air guide 60. For example, it can be... Figure 5 As observed, the connecting pin 723 is rotatably disposed on one side of the first mounting plate 61 or the air guide 60. Another connecting pin 723 is rotatably disposed on the connecting auxiliary portion 733 of the first blade 730.
[0090] Figure 11 The structure of the first blade 730 is shown in detail. In the first blade 730, a framework is formed by a generally plate-shaped first blade body 731. The first blade body 731 is rectangular. The first blade body 731 may have an area capable of shielding the second air outlet 18. That is, the first blade 730 closes the second air outlet 18 so that air cannot be discharged through the second air outlet 18 in a specific mode.
[0091] First connecting rod connection portions 732 are provided at both ends of the inner surface of the first blade body 731. The first connecting rod connection portions 732 can be orthogonal to the first blade body 731. The first connecting rod connection portions 732 are generally plate-shaped. A first hole 732' and a second hole 732'' are formed in the first connecting rod connection portions 732. A connecting pin 713' of the first blade drive portion 713 located in the drive link 710 passes through the first hole 732'. The connecting pin 723 of the first blade link 720 is rotatably inserted into the second hole 732''.
[0092] In this embodiment, four first blade connecting rods 720 are used to make the first blade 730 rotatable relative to the air guide 60. Two connecting rod auxiliary parts 733 are provided on the first blade 730 for two of the four first blade connecting rods 720 to be engaged. For example, it is possible to... Figure 11 As observed, two first-blade connecting rods 720 are inserted into and hooked into the connecting rod connection auxiliary part 733, and the remaining first-blade connecting rods 720 are inserted into and hooked into the second hole 732'' of the two first connecting rod connection parts 732.
[0093] The second blade connecting rod 740 functions to connect the second blade 750 to the drive connecting rod 710 and transmit the driving force of the drive source 700 to the second blade 750. The structure of the second blade connecting rod 740 is shown in detail in [the diagram / illustration]. Figure 12 The second connecting rod body 741 forms the skeleton of the second blade connecting rod 740. The second connecting rod body 741 is a flat and long plate. A connecting pin 741' is formed at one end of the second connecting rod body 741. The connecting pin 741' is rotatably connected to the second blade 750 side. A hanging flange 741'' protrudes from the free end of the connecting pin 741'. The hanging flange 741'' protrudes orthogonally to the extending direction of the connecting pin 741'.
[0094] A connecting hole 742' is formed on the opposite end of the second connecting rod body 741 relative to the end where the connecting pin 741' is located. The connecting hole 742' is used to connect with the drive connecting rod 710. A flange through hole 742'' is formed on one side of the connecting hole 742'. The flange through hole 742'' connects with the connecting hole 742'. The flange through hole 742'' is a portion into which the connecting pin 715 located on the second blade drive portion 714 of the drive connecting rod 710 can be rotatably inserted. The hanging flange 716 of the connecting pin 715 is movably hooked to the opposite side of the second connecting rod body 741 through the flange through hole 742''.
[0095] The second blade 750 is located within the flow path of the air guide 60 and serves to guide the passing air. For example, it can be... Figure 13 As observed, the second blade 750 has a framework formed by an elongated rectangular second blade body 751. The lateral length of the second blade body 751 is approximately the same as the lateral length of the first blade body 731. The front-to-back width of the second blade body 751 is relatively narrower compared to the front-to-back width of the first blade body 731.
[0096] Second connecting rod connection portions 752 are provided at both ends of the second blade body 751. The second connecting rod connection portions 752 are formed to protrude in one direction from both ends of the second blade body 751. Connecting pins 741' of the second blade connecting rod 740 are connected to the second connecting rod connection portions 752. For this purpose, connecting holes 752' are formed in the second connecting rod connection portions 752. The connecting pins 741' of the second blade connecting rod 740 are rotatably inserted into the connecting holes 752'. Hanging flange through holes 752'' are formed in the connecting holes 752'. The hanging flange 741'' of the second blade connecting rod 740 is movably hooked onto the opposite side of the second connecting rod connection portion 752 through the hanging flange through holes 752''.
[0097] In the second blade body 751, a connecting auxiliary portion 753 is provided at a predetermined interval between the second connecting rod connecting portions 752 located at both ends. A rotation center shaft 753' is provided in the connecting auxiliary portion 753. The rotation center shaft 753' is rotatably attached to the second hanging piece 61' on the air guide member 60.
[0098] Rotation center shafts 755 are respectively provided at both ends of the second blade body 751. As shown in general Figure 5 As shown in the diagram, the rotation center shaft 755 is rotatably disposed on one side of the inner surface of the flow path 60' of the air guide 60.
[0099] In the illustrated embodiment, the lateral length of the first blade 730 and the second blade 750 is longer than their front-to-back width. Therefore, the drive source 700 and drive linkage 710 are provided at both ends of the first blade 730 and the second blade 750, allowing the first blade 730 and the second blade 750 to move uniformly along their entire lateral length. Thus, a structure that links with the drive linkage 710 is provided at both ends of the first blade 730 and the second blade 750. However, if the lateral length of the first blade 730 and the second blade 750 is short, the drive source 700, drive linkage 710, and other structures can be provided only on one side. The same applies to the first blade linkage 720, the second blade linkage 740, and the connecting auxiliary part 753.
[0100] The operation of the air conditioning device of the present invention having the configuration described above will be explained below.
[0101] First, such as Figure 14 As shown in (a), when the first blade 730 blocks the second air outlet 18, air can only be discharged through the first air outlet 17. At this time, the second blade 750 guides the air towards the first air outlet 17. As air is discharged through the first air outlet 17, it is guided by the inclined surface 66 and the transverse blade 67 to be discharged towards the upper front of the first air outlet 17. Therefore, the heat-exchanged air is discharged towards a relatively high position in the air-conditioning space, i.e., above the user's head, so that the heat-exchanged air does not directly contact the user. As described above, Figure 15 The diagram shows that the air that has undergone heat exchange is guided and discharged only through the first air outlet 17.
[0102] When air is discharged through the second air outlet 18, the first blade 730 actuates and opens the second air outlet 18. Furthermore, the amount of air discharged through the second air outlet 18 changes depending on the degree to which the first blade 730 opens the second air outlet 18, and the direction of the air discharged through the second air outlet 18 changes depending on the angle at which the first blade 730 is positioned at the inlet of the second air outlet 18. Figure 14 In (b), an example of the second air outlet 18 being open is shown.
[0103] As described above, in order for the first blade 730 to open the second air outlet 18 so that the heat-exchanged air can be discharged through the first air outlet 17 and the second air outlet 18, the first blade 730 and the second blade 750 need to operate.
[0104] The second blade 750 is driven simultaneously with the first blade 730 via a drive linkage 710. Therefore, as the first blade 730 moves, the angle of the second blade 750 also changes.
[0105] To drive the first blade 730 and the second blade 750, the drive source 700 of the blade assembly 70 is activated. If the drive source 700 is driven to rotate the drive shaft, the drive link 710 rotates. Due to the rotation of the drive link 710, the first blade drive unit 713 and the second blade drive unit 714 operate simultaneously. Under the action of the first blade drive unit 713, the first blade 730 actuates. The second blade link 740, under the action of the second blade drive unit 714, actuates the second blade 750.
[0106] To observe it in more detail, if the drive link 710 is... Figure 14 Based on (a), the drive source 700 rotates in the direction of arrow A, causing the first blade drive unit 713 to move its connecting pin 713'' in the direction of arrow A'. Therefore, the first blade 730 rotates and, based on the attached diagram, moves to the lower left. At this time, the first blade 730's movement trajectory is formed by the first blade connecting rod 720. The first blade 730 will not protrude further beyond a certain range; instead, the first blade 730 rotates around the part where the first blade connecting rod 720 connects to the air guide 60.
[0107] On the other hand, the second blade connecting rod 740, connected to the second blade driving part 714 of the driving connecting rod 710, drives the second blade 750, and the second blade 750 moves along a circular trajectory with the rotation center axis 755 as the center. Therefore, as Figure 14 As shown in (a), the second blade link 740 rotates in the direction of arrow B, and the second blade 750 moves along a circular trajectory in the direction of arrow B' with the rotation center axis 755 as a reference.
[0108] Thus, if the drive linkage 710 rotates by a predetermined angle, the second air outlet 18 is opened. Figure 14 In the state shown in (b), the air that has undergone heat exchange is also discharged through the second air outlet 18. At this time, the direction of air transfer after heat exchange is determined based on the angle at which the first blade 730 is tilted forward and downward with reference to the attached drawing.
[0109] In addition, Figure 16The diagram shows the first blade 730 opening the second air outlet 18, allowing the heat-exchanged air to be simultaneously discharged through the first air outlet 17 and the second air outlet 18. It can be observed that the airflow discharged through the first air outlet 17 and the airflow discharged through the second air outlet 18 merge in front of the shroud 10. This is because the air guided by the first blade 730 and discharged through the second air outlet 18 has a relatively faster velocity than the air discharged through the first air outlet 17; therefore, according to Bernoulli's principle, the two airflows, creating a pressure difference, merge in front of the shroud 10.
[0110] From Figure 17 The diagram clearly shows this state. That is, the farther away from the imaginary extension line of the first blade 730, the more the airflow discharged from the second outlet 18 moves and flows upward from the blade extension line.
[0111] exist Figures 18 to 23 The diagram illustrates the operating modes based on the angle variations of the first blade 730 and the second blade 750. These operating modes are described with reference to the first blade 730. The basic modes of the first blade 730 include a shut-off mode (air is exhausted through the first air outlet 17), a cooling mode, and a heating mode. Figure 18 The basic state of the cooling mode is shown in the diagram. Figure 23 The basic state of the heating mode is shown in the figure.
[0112] like Figure 18 As shown, in cooling mode, the blade angle A formed by the first blade 730 is 0° to 35°. Furthermore, the height difference B between the first blade 730 and the second blade 750 is 0 mm or more. If... Figure 18 Based on the attached figure, the blade angle A of the first blade 730 is 20° and the height difference B is 1.5 mm.
[0113] exist Figure 23 In the basic state of the heating mode shown, the first blade 730 has a blade angle A between 50° and 90°. The second blade 750 rotates to a position where it does not contact the rear guide 22 so that the direction of the rear airflow is maximally directed downwards.
[0114] exist Figures 18 to 23 The diagram shows a total of six modes, including the basic states of cooling and heating, and illustrates the sequential changes in the angles of the first blade 730 and the second blade 750. By operating in one of these six modes (including the basic states of cooling and heating), air can be simultaneously discharged from the first air outlet 17 and the second air outlet 18, thereby achieving both cooling and heating. It can be seen that from... Figures 18 to 23The first blade 730 is gradually adjusted from the lower front part of the air conditioning device to a more downward part.
[0115] While the blade angle can be set and the air conditioning performed in any of the six modes, the air conditioning can also be performed in an oscillating mode that repeatedly changes the blade angle within a specified range between the cooling and heating modes.
[0116] While the foregoing has described how all the constituent elements constituting the embodiments of the present invention operate in combination with one or more of them, this does not mean that the present invention must be limited to such embodiments. That is, as long as it is within the scope of the purpose of the present invention, all the constituent elements can also be selectively combined with more than one of them to operate.
