Description

Technical Field

[0001] The following description relates to an air conditioner, and more particularly, to an air conditioner that changes an air exhaust method. Background Art

[0002] Generally, an air conditioner is a device that uses a refrigeration cycle to control temperature, humidity, airflow, distribution, etc. suitable for human activities. The main components that form the refrigeration cycle include a compressor, a condenser, an evaporator, a blower, etc.

[0003] Air conditioners can be divided into standalone split-type air conditioners, in which the indoor and outdoor units are installed separately, and integrated air conditioners, in which the indoor and outdoor units are installed together in a single housing. The indoor unit of a standalone split-type air conditioner includes a heat exchanger that performs heat exchange on the air drawn into the panel, and a blower that draws interior air into the panel and blows the drawn air into the room. The indoor unit of a conventional air conditioner is manufactured to minimize its heat exchanger, increase the blower's revolutions per minute (RPM), and maximize wind speed and air volume. As a result, the exhaust temperature is reduced, and the exhausted air forms a narrow and long flow path before being discharged into the indoor space.

[0004] When the user is in direct contact with the discharged air, the user may feel cold and uncomfortable; however, when the user is not in direct contact with the discharged air, the user may feel hot and uncomfortable.

[0005] In addition, as the blower's RPM increases to achieve a high wind speed, the blower's noise increases. Radiant air conditioners that do not use a blower to condition the air require a large panel to achieve the same performance as air conditioners that use a blower. Furthermore, the air conditioning speed is slow and incurs high manufacturing costs. Summary of the Invention

[0047] The embodiments described in this specification and the configurations shown in the drawings are merely exemplary embodiments of the present disclosure, and at the time of filing of the present application, there may be various modifications that can replace the embodiments in this specification and the drawings.

[0048] In each of the drawings in this specification, the same reference numerals or symbols represent components or elements that perform substantially the same function.

[0049] The terms used in this specification are only used to describe specific embodiments and are not intended to limit and / or constrain the present disclosure. Expressions used in the singular encompass plural expressions unless they have a clear different meaning in the context. In this specification, it should be understood that terms such as "including", "having" etc. are intended to indicate the presence of features, numbers, steps, actions, components, parts or combinations thereof disclosed in the specification, but are not intended to exclude the possibility that one or more other features, numbers, steps, actions, components, parts or combinations thereof may exist or may be added.

[0050] It should be understood that although the terms "first," "second," etc. are used herein to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first element discussed below may be referred to as the second element, and similarly, the second element may be referred to as the first element without departing from the teachings of the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the relevant listed items.

[0051] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings.

[0052] The refrigeration cycle of an air conditioner consists of a compressor, condenser, expansion valve, and evaporator. This refrigeration cycle has a series of processes, including compression, condensation, expansion, and evaporation, exchanging heat between high-temperature air and low-temperature refrigerant, and then supplying the low-temperature air to the interior space.

[0053] The compressor compresses refrigerant gas at high temperature and high pressure and discharges the compressed refrigerant gas into the condenser. The condenser condenses the compressed refrigerant into a liquid state, dissipating the heat around the condenser through the condensation process. The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed by the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded by the expansion valve. The evaporator achieves a cooling effect by exchanging the refrigerant's latent heat of vaporization with the object to be cooled, and returns the low-temperature, low-pressure refrigerant gas to the compressor. This cycle controls the air temperature in the indoor space.

[0054] The outdoor unit of the air conditioner includes a compressor of a refrigeration cycle and an outdoor heat exchanger. The expansion valve may be provided in either the indoor unit or the outdoor unit, and the indoor heat exchanger is located in the indoor unit of the air conditioner.

[0055] The present disclosure relates to an air conditioner for air conditioning an indoor space, and an outdoor heat exchanger serves as a condenser and an indoor heat exchanger serves as an evaporator. Hereinafter, for convenience, an indoor unit including an indoor heat exchanger is referred to as an air conditioner, and the indoor heat exchanger is referred to as a heat exchanger.

[0061] The air conditioner 1 may include a discharge blade 50 that opens / closes the outlet 14. The discharge blade 50 is rotatably provided in the housing 10. Specifically, the discharge blade 50 may be rotatable relative to the discharge plate 20 around a blade shaft 59. The blade shaft 59 may be provided on the inner surface of the discharge plate 20.

[0062] The discharge vane 50 is movable between a closed position 50b, in which the outlet 14 is closed, and a guiding position 50a, in which the outlet 14 is open and the direction of the air blown from the blower 45 to be discharged to the outlet 14 is controlled. The guiding position 50a is a position in which the discharge vane 50 opens the outlet 14 and guides the air discharged through the outlet 14 within a predetermined angular range, wherein the discharge vane 50 controls the direction of the discharged air. The air conditioner 1 can control the airflow from the blower 45 to the discharge plate 20 or the outlet 14 by moving the discharge vane 50 between the guiding position 50a and the closed position 50b. When the discharge vane 50 is in the guiding position 50a, both the outlet 14 opening operation and the airflow to the discharge plate 20 are blocked. When the discharge vane 50 is in the closed position 50b, both the outlet 14 closing operation and the airflow to the discharge plate 20 are unblocked are blocked.

[0063] The air conditioner 1 may include an auxiliary blade 70 that controls the direction of the air blown out from the blower 45 within the discharge vane 50. The discharge vane 50 can control the blown air in the vertical direction, and the auxiliary blade 70 can control the blown air in the horizontal direction. At least one auxiliary blade 70 may be provided. In the current embodiment, a plurality of auxiliary blades 70 are spaced apart from each other in the horizontal direction by a predetermined distance. The plurality of auxiliary blades 70 may be arranged in the longitudinal direction of the outlet 14. The auxiliary blade 70 may be disposed within the discharge vane 50 so as not to be exposed to the outside when the discharge vane 50 is in the closed position 50b.

The sensor receiving member 72 may be covered by the discharge blade 50 when the discharge blade 50 is in the closed position 50b. Even when the sensor receiving member 72 is covered by the discharge blade 50, the sensor receiving member 72 senses a signal through the plurality of holes 22 formed in the discharge blade 50 and transmits the signal to a controller (not shown), so that the air conditioner 1 can operate.

[0065] Figure 5 and Figure 6 is a view showing the operation of the air conditioner according to an embodiment of the present disclosure. Figures 4 to 6 The operation of the air conditioner according to the embodiment of the present disclosure is described.

[0066] The heat exchanger 40 may be provided inside the housing 10 and may be provided on an air movement path from the inlet 12 to the outlet 14. The heat exchanger 40 is configured to absorb heat from the air introduced into the inlet 12 or to transfer heat to the air. A drain panel 42 may be provided below the heat exchanger 40 to collect moisture condensed in the heat exchanger 40. The drain panel 42 may be connected to a drain hose (not shown) connected to the outside of the housing 10 and may discharge the condensed moisture to the outside of the housing 10.

[0067] The blower 45 is provided inside the housing 10. The blower 45 is configured to blow air so that the air may flow from the inlet 12 to the outlet 14 or the discharge plate 20. The blower 45 may be a cross-flow fan having the same longitudinal direction as that of the housing.

[0068] The air conditioner 1 may include a flow path guide 74. The flow path guide 74 is configured to guide air blown out from the blower 45.

[0069] The flow path guide 74 may include a first flow path guide 76 and a second flow path guide 78 .

[0070] The first flow path guide 76 is provided to form a first flow path 75a for air to flow from the blower 45 to the outlet 14. The first flow path 75a may be connected to the outlet 14. The outlet 14 may be provided at one end of the first flow path guide 76. The outlet 14 may be provided on an extension line of the air movement path guided by the first flow path guide 76.

[0071] The second flow path guide 78 is configured to form a second flow path 75b. The second flow path 75b may be connected to the plurality of holes 22. Specifically, the second flow path 75b is formed by the second flow path guide 78 and the inner surface of the discharge plate 20, and air flowing in the second flow path 75b may be discharged to the outside of the housing 10 through the plurality of holes 22 of the discharge plate 20. The second flow path 75b diverges from the first flow path 75a, and air flows into the plurality of holes 22. A guide opening 77 is formed in the second flow path guide 78 so that air flowing in the first flow path 75a can flow into the second flow path 75b. The drainage panel 42 described above may be disposed on the rear surface of the second flow path guide 78.

[0072] The second flow path guide 78 may include a curved guide 79. The curved guide 79 may be formed as a curved surface to allow for the rotation of the discharge blade 50. The curved guide 79 may form a rotation space 79a (described later) for the flow path gate portion 54 of the discharge blade 50. The rotation space 79a is a space that forms a portion of the second flow path 75b and in which the flow path gate portion 54 is rotatable. Due to the influence of the rotation space 79a formed within the curved guide 79, the discharge blade 50 is not disturbed by the curved guide 79 and can rotate.

[0073] The discharge vane 50 is rotatable and movable between a guide position 50a and a closed position 50b. The discharge vane 50 is operable to selectively block the first flow path 75a and the second flow path 75b. When the discharge vane 50 is in the closed position 50b, the discharge vane 50 can close the outlet 14. In addition, the discharge vane 50 is configured to cover the sensor receiver 72 in the closed position 50b, so that the internal configuration of the housing 10 is not exposed to the outside.

[0074] The discharge vane 50 may include a vane body 52 and a plurality of vane holes 56 .

[0075] The blade body 52 may be formed to be rotatable about the blade shaft 59. The blade body 52 may be configured to correspond to the outlet 14. The blade body 52 may have a substantially plate shape. A plurality of blade holes 56 may be distributed in the blade body 52, and the width of each of the blade holes 56 may be smaller than the width of the outlet 14. In addition, even when the discharge blade 50 is in the closed position 50b, air can be discharged to the outside of the housing 10 through the plurality of blade holes 56 of the discharge blade 50. The plurality of blade holes 56 and the plurality of holes 22 of the discharge plate 20 may also have the same size and the same shape, or different sizes and different shapes.

[0076] The blade body 52 may include a guide portion 53 and a flow path gate portion 54. The guide portion 53 and the flow path gate portion 54 may be integrally formed.

[0077] When the discharge blade 50 is at the guide position 50a, the guide portion 53 controls the direction of air blown from the blower 45 and discharged toward the outlet 14. The guide portion 53 can change the direction of air discharged to the outside of the housing 10 according to the rotation angle centered on the blade shaft 59.

[0078] In the guide position 50a, the flow path gate portion 54 extends from the guide portion 53 and is configured to block air flowing in the second flow path 75b. When the discharge vane 50 is in the guide position 50a, the flow path gate portion 54 is configured to move along the rotation space 79a formed by the curved guide member 79. In other words, when the discharge vane 50 is in the guide position 50a, the flow path gate portion 54 is configured to block the second flow path 75b. In the guide position 50a, the guide portion 53 moves to the exterior of the housing 10, and the flow path gate portion 54 moves relatively to the interior of the housing 10.

[0079] In the following, reference will be made to Figure 4 、 Figure 5 and Figure 6 The operation of the air conditioner according to the present disclosure is described.

[0080] First, a case where the discharge vane 50 is in the closed position 50 b will be described.

[0081] like Figure 4 As shown in FIG, when the discharge vane 50 is in the closed position 50b, the outlet 14 is closed by the discharge vane 50, and the second flow path 75b is opened. Therefore, the air blown out from the blower 45 flows in the first flow path 75a and the second flow path 75b to be discharged to the outside of the housing 10 through the plurality of holes 22 of the discharge plate 20 and the plurality of vane holes 56 of the discharge vane 50.

[0082] Next, a case where the discharge blade 50 is in the guide position 50 a will be described.

[0083] like Figure 5 and Figure 6 As shown in FIG, when the discharge blade 50 is in the guide position 50a, the outlet 14 is open, and the second flow path 75b is blocked by the flow path door portion 54. That is, the air blown out from the blower 45 can flow only through the first flow path 75a.

[0084] Therefore, the air blown out from the blower 45 flows along the first flow path 75 a and is discharged to the outside of the housing 10 through the outlet 14 .

[0085] Hereinafter, coupling and detachment of the discharge plate 20 in the air conditioner 1 will be described.

[0086] Figure 7 and Figure 8 is a view illustrating disassembly of the air conditioner according to the embodiment of the present disclosure.

[0087] The discharge plate 20 can be detachably provided at the housing 10. The housing 10 may include a front frame 30 inside the discharge plate 20, wherein the discharge plate 20 can be coupled to the front frame 30. That is, the discharge plate 20 can be detachably provided at the front frame 30. The front frame 30 may include a second flow path guide 78.

[0088] At least one coupling groove may be formed in any one of the discharge plate 20 and the front frame 30 , and at least one coupling protrusion to be inserted into and coupled to the at least one coupling groove may be formed in the other one of the discharge plate 20 and the front frame 30 .

[0089] In the current embodiment, the discharge plate 20 may include a first coupling member 62 protruding from a surface facing the front frame 30 and a first coupling groove 63 formed as a recessed portion in one end of the first coupling member 62. In addition, the front frame 30 may include a first coupling protrusion 32 to be inserted into and coupled with the first coupling groove 63 of the discharge plate 20.

[0090] The first coupling member 62 includes a pair of elastic legs 62a that are both resilient and stretchable. Specifically, the pair of elastic legs 62a of the first coupling member 62 elastically deform and stretch when the first coupling protrusion 32 is inserted into the first coupling groove 63. When the first coupling protrusion 32 is inserted into the first coupling groove 63, the pair of stretched elastic legs 62a elastically recover. This configuration prevents the first coupling protrusion 32 from disengaging from the first coupling groove 63.

[0091] In addition, the front frame 30 may include a second coupling member 34 protruding from a surface facing the discharge plate 20 and a second coupling groove 35 recessed in one end of the second coupling member 34. The discharge plate 20 may include a second coupling protrusion 64 to be inserted into and coupled to the second coupling groove 35 of the front frame 30.

[0092] The second coupling member 34 includes a pair of elastic legs 34a that are both resilient and stretchable. Specifically, the pair of elastic legs 34a of the second coupling protrusion 64 elastically deform and stretch when the second coupling protrusion 64 is inserted into the second coupling groove 35. When the second coupling protrusion 64 is inserted into the second coupling groove 35, the pair of stretched elastic legs 34a elastically recover. This configuration prevents the second coupling protrusion 64 from disengaging from the second coupling groove 35.

[0093] At least one insertion hole 36 may be formed in any one of the discharge plate 20 and the front frame 30, and at least one hook 66 hooked with the at least one insertion hole 36 may be formed in the other of the discharge plate 20 and the front frame 30. In the current embodiment, the hook 66 protruding from the surface facing the front frame 30 may be formed in the discharge plate 20, and the insertion hole 36 is formed in the front frame 30 at a position corresponding to the hook 66 so that the hook 66 can hook the insertion hole 36.

[0094] The hook 66 may be coupled to the insertion hole 36 to bear only the weight of the discharge plate 20. With this configuration, when the first coupling member 62 and the first coupling protrusion 32 are separated from each other and the second coupling member 34 and the second coupling protrusion 64 are separated from each other, the hook 66 may be easily detached from the insertion hole 36.

[0095] In the current embodiment, the first coupling member 62, the second coupling protrusion 64 and the hook 66 are sequentially provided in the discharge plate 20, and the first coupling protrusion 32, the second coupling member 34 and the insertion hole 36 are sequentially provided in the front frame 30. However, the order is not limited thereto.

[0096] The coupling members 34 and 62 , the coupling protrusions 32 and 64 , the hook 66 and the insertion hole 36 are spaced apart from each other by a predetermined distance in a horizontal direction as a longitudinal direction of the air conditioner 1 , so that the discharge plate 20 can be stably coupled to the front frame 30 .

[0097] The discharge plate 20 may include step prevention protrusions 68 protruding from both ends of the discharge plate 20. A pair of step prevention protrusions 68 may be provided at the left and right ends of the discharge plate 20.

[0106] The discharge plate 220 may include a plurality of holes 222 , and the discharge vane 250 may include a plurality of vane holes 256 .

[0107] A portion of the plurality of holes 222 in one section of the discharge plate 220 may have a size that is larger than a portion of the plurality of holes 222 in another section of the discharge plate 220. Similarly, a plurality of vane holes 256 in one section of the discharge vane 250 may have a size that is larger than a plurality of vane holes 256 in another section of the discharge vane 250.

[0108] In the current embodiment, the discharge plate 220 may include a first section 221a and a second section 221b. The size of the plurality of holes 222a in the first section 221a may be larger than the size of the plurality of holes 222b in the second section 221b. The second section 221b may be provided on the left and right sides of the first section 221a. With this configuration, the wind speed of the air discharged through the holes 222a in the first section 221a may be faster than the wind speed of the air discharged through the plurality of holes 222b in the second section 221b, so that the air discharged through the plurality of holes 222 of the discharge plate 220 may be discharged linearly forward.

[0109] In addition, the discharge blade 250 may include a first blade portion 251a and a second blade portion 251b.

[0113] The discharge blade 50 may also include a partitioning protrusion 58 .

[0114] The partition protrusion 58 may protrude from the blade body 52 to be spaced apart a predetermined distance from the outlet forming portion 15. The partition protrusion 58 may be spaced apart a predetermined distance from the outlet forming portion 15 with a predetermined gap therebetween.

[0115] When blade body 52 and outlet-forming portion 15 come into contact with each other, heat-exchanged air stagnates between them and forms water droplets within blade body 52 due to the temperature difference between the inner and outer surfaces of blade body 52. ​​Due to the effect of partitioning protrusion 58, blade body 52 and outlet-forming portion 15 can be spaced a predetermined distance apart from each other, allowing a small amount of air to be discharged to the outside of housing 10 through the predetermined gap, thereby preventing this phenomenon from occurring. With this configuration, heat-exchanged air flows along the outer surface of blade body 52, preventing water droplets from forming within blade body 52.

[0116] Hereinafter, an air conditioner according to an embodiment of the present disclosure will be described. Description of the same configuration as that described above will be omitted.

The movable blade 384 can slide downward so that at least a portion of the movable blade 384 protrudes toward the discharge blade 350 and the movable blade 384 contacts the discharge blade 350. With this configuration, the air blown from the blower 45 can flow along the first flow path 75a and can be discharged through the plurality of blade holes 356 of the discharge blade 350 and the plurality of holes 385 of the movable blade 384.

[0130] like Figure 18 As shown in FIG, the fourth mode is an operating mode in which air blown from the blower 45 is discharged through the plurality of holes 22 of the discharge plate 320, the plurality of blade holes 356 of the discharge vane 350, and the plurality of holes 385 of the movable vane 384. The discharge vane 350 is set to the closed position 350b and closes the outlet 14, and the flow path vane 380 is set to open the second flow path 75b. The movable vane 384 can slide downward so that at least a portion of the movable vane 384 protrudes toward the discharge plate 320 and contacts the discharge vane 350. With this configuration, the air blown from the blower 45 flows along the first flow path 75a and the second flow path 75b and can be discharged to the outside of the housing 310 through the plurality of holes 22 of the discharge plate 320, the plurality of holes 385 of the movable vane 384, and the plurality of blade holes 356 of the discharge vane 350.
