Description

Technical Field

[0001] This invention relates to air conditioners, and more specifically, to an air conditioner that discharges air through an upper outlet. Background Technology

[0002] Generally, an air conditioner is a device that uses a refrigerant refrigeration cycle consisting of a compressor, condenser, expansion mechanism, and evaporator to cool or heat the room or purify the air in order to create a more comfortable indoor environment for users.

[0003] Based on their installation location, air conditioner indoor units can be divided into ceiling-mounted, wall-mounted, and floor-standing types. In floor-standing indoor units, the discharge port can be located on the front or side of the unit, while the intake port can be located on the back of the unit.

[0004] In a vertical indoor unit, the air that has passed through the heat exchanger is discharged through outlets located on both sides of the casing.

[0005] In this regard, the prior art (Korean Patent Publication No. 10-2016-0132321, Publication Date: November 17, 2016, Invention Title: Air Conditioner and Control Method Thereof) includes: a cover having an inlet and an outlet; a heat exchanger disposed inside the cover; a fan that draws in air from the inlet, exchanges heat between the drawn-in air and the heat exchanger, and discharges the air through the outlet; and an airflow control device that controls the air around the inlet and outlet and the airflow discharged from the outlet.

[0006] However, the existing technology only has one air supply fan that guides the air that has passed through the heat exchanger to the exhaust port located on the upper side. Therefore, there is a problem that the performance of the upper exhaust air is reduced due to the small amount of exhaust air discharged from the upper part.

[0007] In addition, since indirect airflow cannot be achieved through an outlet located on the top in existing technologies, there is a problem of decreased consumer satisfaction. Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] The purpose of this invention is to provide an air conditioner that can improve the performance of the upper exhaust airflow by increasing the number of fans that guide the air that has passed through the heat exchanger to the upper exhaust port.

[0010] In addition, the present invention aims to provide an air conditioner that achieves indirect airflow through an outlet located on the upper side of the air conditioner, thereby improving consumer satisfaction.

[0011] The objectives of this invention are not limited to those mentioned above. Other objectives and advantages of the invention not mentioned can be understood from the following description, and will become even clearer through embodiments of the invention. Furthermore, it is apparent that the objectives and advantages of the invention can be achieved through the means set forth in the claims and combinations thereof.

[0012] Technical solutions to the problem

[0013] The technical feature of the air conditioner of the present invention for solving the above problems is that it utilizes air moving from the air supply module to the upper side of the casing to form direct airflow.

[0014] Specifically, the air discharged upward from the first air supply module can form a direct airflow that is discharged towards the front of the auxiliary duct section through the upper outlet.

[0015] In addition, the technical feature of the air conditioner of the present invention is that the air moving through the auxiliary duct section forms an indirect airflow that is discharged in front of the auxiliary duct section.

[0016] Specifically, the air expelled from the air supply modules other than the one located at the top of the air supply module section can form an indirect airflow that is discharged in front of the auxiliary duct section after moving through the auxiliary duct section.

[0017] In addition, the technical feature of the air conditioner of the present invention is that the upper concentrated air discharge is achieved by blocking the discharge port provided on the side of the casing.

[0018] Specifically, if the front door moves and blocks the side outlet, the air discharged from the second and third air supply modules forms indirect air through the auxiliary pipeline, and the air discharged from the first air supply module forms direct air through the upper outlet. Therefore, it can provide concentrated upper air supply to the upper part of the box.

[0028] In addition, the extension duct section is located on both sides of the upper outlet on the upper side of the air supply module section in the width direction.

[0029] In addition, the two sides of the discharge pipe section are connected to the extension pipe section, and the discharge outlet is located on the lower side of the discharge pipe section. The first door section is used to open and close the discharge outlet.

[0030] Additionally, the first door may include: a first drive unit fixed to the discharge pipe section and supplying rotational power; and a first movable door connected to the first drive unit and rotating by the action of the first drive unit to open and close the discharge outlet.

[0031] Additionally, the second door may include a second movable door, which is connected to a second drive unit mounted on the cover bracket and moves in the direction of opening and closing the upper outlet located on the upper side of the air supply module.

[0032] In addition, the present invention may also include a front door, which opens and closes side outlets located on the left and right sides of the housing.

[0033] Additionally, the front door may include: a front drive unit fixed to the housing and supplying rotational power; and a front movable door connected to the front drive unit and moved by the movement of the front drive unit to open and close the side outlet.

[0056] [Overall Composition]

[0057] Hereinafter, an air conditioner 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0058] Figure 1 This is a front perspective view of an air conditioner 1 according to an embodiment of the present invention. Figure 2 This is a rear perspective view of an air conditioner 1 according to an embodiment of the present invention. Figure 3 This is a cross-sectional view of an air conditioner 1 according to an embodiment of the present invention.

[0059] like Figures 1 to 3 As shown, an air conditioner 1 according to an embodiment of the present invention includes an indoor unit and an outdoor unit. The indoor unit of the air conditioner 1 will be described in this invention. The air conditioner 1 according to an embodiment of the present invention may include at least one of a housing 5, a heat exchanger 60, an air supply module 70, an auxiliary piping section 120, a first door 140, a second door 150, and a front door 160.

[0060] [Box]

[0061] An air conditioner 1 according to an embodiment of the present invention includes a housing 5, the housing 5 having an intake for air to flow in and an exhaust for air to be discharged 10.

[0062] The housing 5 can be modified in various ways within the technical concept of forming an air intake port on the back and an air exhaust port 10 on at least one of the front, side, and upper sides. One embodiment of the housing 5 may include: a first cover 20, with the air intake port formed behind the first cover 20 and a space for arranging a heat exchanger 60 formed on its inner side; and a second cover 30, continuously disposed above the first cover 20.

[0063] A support cover 50 is provided on the lower side of the first cover 20. Electrical components can be installed inside the support cover 50, but no air circulation path is provided.

[0064] [First Cover]

[0065] The first cover 20 is shaped to surround the heat exchanger 60 and the air supply module 70. The intake port is formed on the back, and the exhaust ports 10 are provided on the left and right sides at the front of the first cover 20. The first cover 20 has a box shape, and a filter 170 can be provided at the intake port.

[0066] Furthermore, the upper side of the first cover 20 connected to the second cover 30 is open, or a pipe connected to the inner pipe 34 of the second cover 30 is provided inside the first cover 20.

[0067] [Second Shield]

[0068] The second cover 30 can be modified in various ways within the technical concept of connecting to the upper side of the first cover 20 and providing a duct that guides the air blown from the air supply module 70 upwards. In one embodiment of the present invention, the second cover 30 may include a second cover body 32, cover blades 40, cover bracket 42, and guide groove 44.

[0069] The second housing body 32 is connected to the upper side of the first housing 20 and has an inner duct 34 that guides air blown from the air supply module 70 upward. The inner duct 34 is connected to the uppermost first air supply module 80 in the air supply module 70. The inner duct 34 is arranged in an upward inclined direction, so as to be inclined upward from the lower side of the inner duct 34 toward the front of the housing 5. Therefore, the air moving along the inner duct 34 to the upper front of the housing 5 forms a direct airflow that is discharged toward the front of the auxiliary duct section 120.

[0070] An upper discharge port 36 is provided on the upper side of the inner pipe 34. Therefore, air moving upward along the inner pipe 34 is discharged to the upper side of the second cover 30 through the upper discharge port 36. Furthermore, a cover blade 40 is provided on the upper side of the second cover body 32 with the upper discharge port 36. The cover blade 40 is inclined towards the upper front of the housing 5, so the air discharged through the upper discharge port 36 is discharged obliquely through the cover blade 40.

[0071] The cover bracket 42 is disposed inside the second cover body 32 and supports the second drive part 152 disposed on the second door part 150. Furthermore, a guide groove 44 is provided on the upper side of the second cover 30 to guide the movement of the second door part 150 for opening and closing the upper outlet 36.

[0072] [Heat Exchanger]

[0073] The heat exchanger 60 can be modified in various ways within the scope of the technical concept of being located inside the housing 5 and exchanging heat with the air flowing in through the intake port.

[0074] The heat exchanger 60 is located behind the air supply module 70. The heat exchanger 60 is positioned between the intake and exhaust ports 10 and can exchange heat with the air flowing inside the indoor unit. Alternatively, the heat exchanger 60 can be positioned between the filter 170 and the air supply module 70.

[0075] [Air Supply Module Department]

[0076] The air supply module 70 can be modified in various ways within the technical concept of blowing air that has passed through the heat exchanger 60 toward the outlet 10 by means of rotation, located on the front of the heat exchanger 60.

[0077] Furthermore, the air supply module 70 has a plurality of air supply modules. Some of these modules can blow air toward the auxiliary duct section 120, while the remaining modules can blow air toward the outlet 10. The uppermost air supply module in the air supply module 70 discharges air to the upper side of the second cover 30 through the second cover 30. The remaining air supply modules discharge air to the front of the housing 5 through the left and right sides of the housing 5. However, if the left and right sides of the housing 5 are blocked, indirect airflow is formed, where air is discharged to the front of the auxiliary duct section 120 through the auxiliary duct section 120.

[0078] An embodiment of the present invention may include a first air supply module 80, a second air supply module 90 and a third air supply module 100.

[0079] The first air supply module 80 blows air toward the auxiliary duct section 120 located on the upper side. The first air supply module 80 operates in a direct air mode, blowing air to the lower side of the discharge duct section 130 through the upper discharge port 36 located on the upper side of the air supply module section 70. In the direct air mode, the air discharged from the first air supply module 80 forms a direct airflow that is discharged toward the upper front of the housing 5.

[0080] The first air supply module 80 includes: an air supply motor that supplies rotational power; a first air supply fan 82 connected to the air supply motor; and a first air supply shroud 84 that supports the first air supply fan 82 so that it can rotate, and is disposed on the outside of the first air supply fan 82 to guide the movement of air.

[0081] Air passing through heat exchanger 60 moves to the inside of first air supply shroud 84. Furthermore, due to the operation of first air supply fan 82, air expelled from the outside of first air supply shroud 84 moves to the outside of housing 5. This configuration of the first air supply module 80 is a known configuration, therefore its detailed description is omitted.

[0082] The second air supply module 90 is located below the first air supply module 80, and blows air towards the outlets 10 located on the left and right sides of the housing 5 or towards the extension pipe section 122.

[0083] The second air supply module 90 includes: an air supply motor that supplies rotational power; a second air supply fan 92 connected to the air supply motor; and a second air supply shroud 94 that supports the second air supply fan 92 so that it can rotate, and is disposed on the outside of the second air supply fan 92 to guide the movement of air.

[0084] The third air supply module 100 is located below the second air supply module 90, and blows air toward the outlet 10 or toward the extension duct section 122.

[0085] The third air supply module 100 includes: an air supply motor that supplies rotational power; a third air supply fan 102 connected to the air supply motor; and a third air supply shroud 104 that supports the third air supply fan 102 so that it can rotate, and is disposed on the outside of the third air supply fan 102 to guide the movement of air.

[0086] The air supply module section 70 may only have a first air supply module 80 and a second air supply module 90. As needed, various modifications can be implemented, such as adding an air supply module to the lower side of the third air supply module 100.

[0087] The air supply module 70 of one embodiment of the present invention may further include a first air partition 110, a second air partition 112, a third air partition 114, and a side air partition 116.

[0088] The first air partition wall 110 forms a partition wall between the first air supply module 80 and the second air supply module 90. The first air partition wall 110 is arranged horizontally and protrudes forward from the boundary between the first air supply module 80 and the second air supply module 90. Therefore, it prevents air discharged from the first air supply module 80 from moving towards the second air supply module 90, and prevents air discharged from the second air supply module 90 from moving towards the first air supply module 80, thereby enabling independent air supply operations of both the first and second air supply modules 80 and 90.

[0089] The second air partition wall 112 forms a partition wall between the second air supply module 90 and the third air supply module 100. The second air partition wall 112 is arranged horizontally and protrudes forward from the boundary between the second air supply module 90 and the third air supply module 100. Therefore, it prevents air discharged from the second air supply module 90 from moving towards the third air supply module 100, and prevents air discharged from the third air supply module 100 from moving towards the second air supply module 90, thereby enabling independent air supply operations of both the second air supply module 90 and the third air supply module 100.

[0090] Furthermore, a third air separation wall 114 is formed on the lower side of the third air supply module 100. The third air separation wall 114 is formed on the lower side of the third air supply module 100. The third air separation wall 114 is arranged horizontally and protrudes forward on the lower side of the third air supply module 100. Therefore, it prevents the air expelled from the third air supply module 100 from moving downwards towards the lower side of the third air supply module 100, thereby enabling the air supply operation of the third air supply module 100 to be achieved independently.

[0091] Furthermore, the side air partition 116 forms partition walls on the left and right sides of the first air supply module 80 and is connected to the first air partition 110. The side air partition 116 is formed in the shape of a plate and extends in the vertical direction. Therefore, the air discharged from the first air supply module 80 is guided to the inner pipe 34 located on the upper side of the first air supply module 80.

[0092] [Auxiliary Piping Section]

[0093] The auxiliary piping section 120 can be modified in various ways within the technical concept of protruding upward toward the housing 5 and guiding the air transmitted through the air supply module section 70 upward toward the housing 5 and supplying indirect air discharged toward the front of the housing 5. In one embodiment of the present invention, the auxiliary piping section may include an extension piping section 122 and an exhaust piping section 130.

[0094] The extension duct section 122 has a first inner duct 124 connected to the inside of the housing 5 and extends upward toward the housing 5. The extension duct section 122 is provided on both sides of the upper outlet 36 located above the air supply module section 70 in the width direction. The extension duct section 122 and the first inner duct 124 provided inside the extension duct section 122 extend in the vertical direction and are arranged in a shape facing each other across the upper outlet 36.

[0095] Therefore, the air delivered from the second air supply module 90 and the third air supply module 100 can move along the first inner pipe 124 to the upper side of the extension pipe section 122.

[0096] Furthermore, the discharge pipe section 130 can be modified in various ways within the technical concept of being connected to the upper side of the extension pipe section 122 and having an outlet 132 for discharging air that has moved upward through the extension pipe section 122. In one embodiment of the present invention, the discharge pipe section 130 is connected to the extension pipe section 122 on both sides, and an outlet 132 is provided on the lower side of the discharge pipe section 130. The outlet 132 of the discharge pipe section 130 can be opened and closed using the first door section 140.

[0097] The discharge pipe portion 130 is arranged in a horizontal direction, and a lower side surface of the discharge pipe portion 130 is formed with an inclined surface that slopes upward from the rear toward the front. Therefore, the indirect air discharged to the lower side of the discharge pipe portion 130 can easily be discharged toward the front of the cabinet 5 along the upper side surface of the first movable door 144 provided on the first door portion 140.

[0098] A second inner pipe 134 is provided inside the discharge pipe portion 130. Both sides of the second inner pipe 134 communicate with the first inner pipe 124, and a discharge outlet 132 is connected to the lower side of the central portion of the second inner pipe 134.

[0099] In addition, the discharge pipe portion 130 and the extension pipe portion 122 are formed into a "匚"-shape with an opening at the lower side, and the front surface and the rear surface of the auxiliary pipe portion 120 can be arranged in a shape with openings. Therefore, the direct air discharged to the lower side of the discharge pipe portion 130 and the indirect air discharged from the upper inner portion of the discharge pipe portion 130 can be more easily discharged toward the front of the discharge pipe portion 130.

[0100] [First Door Portion]

[0101] Figure 8 is a cross-sectional view illustrating an operating state of the first door portion 140 according to an embodiment of the present invention.

[0102] as Figure 3 and Figure 8 shown, the first door portion 140 can be variously modified within the technical concept of opening and closing the discharge outlet 132 provided in the auxiliary pipe portion 120. The first door portion 140 according to an embodiment of the present invention may comprise: a first driving part 142 fixed to the discharge pipe portion 130 for providing rotational power; and a first movable door 144 connected to the first driving part 142, which rotates by the operation of the first driving part 142 to open and close the discharge outlet 132.

[0103] The first driving part 142 is a motor fixed to the lower side of the discharge pipe portion 130 and provides rotational power. The first movable door 144 connected to the first driving part 142 rotates by the operation of the first driving part 142 to open and close the discharge outlet 132. In addition, the first movable door 144 has a plate shape, and opens obliquely downward toward the front of the auxiliary pipe portion 120. Therefore, the indirect air discharged downward through the discharge outlet 132 is discharged along the upper side surface of the first movable door 144, so that the indirect air directed toward the front of the auxiliary pipe portion 120 can be formed.

[0104] [Second Door Portion]

[0105] Figure 4 is a cross-sectional view illustrating the second door portion 150 according to an embodiment of the present invention, Figure 5 is a perspective view illustrating the second door portion 150 according to an embodiment of the present invention.

[0106] like Figure 4 and Figure 5 As shown, the second door 150 can be modified in various ways within the technical concept of controlling the air passing through the air supply module 70 and being discharged through the outlet 10. In one embodiment of the present invention, the second door 150 may include: a second drive unit 152, a cover bracket 42 mounted on the housing 5; and a second movable door 154 connected to the second drive unit 152, moving along the direction of opening and closing the upper outlet 36.

[0107] The second drive unit 152 uses a motor that supplies rotational power and is fixed to the cover bracket 42 located inside the second cover 30. A circular gear is provided on the output shaft of the second drive unit 152, and a rack is formed on the second moving door 154 opposite to the circular gear of the second drive unit 152. Therefore, the second drive unit 152 and the second moving door 154 are connected in a rack and pinion manner to perform linear movement.

[0108] The second sliding door 154 includes: a sliding door body 155, which is formed in the shape of a plate; a gear support body 157, which extends horizontally from the sliding door body 155 and is geared to the second drive unit 152; and a guide body 156, which is located on both sides of the gear support body 157 and protrudes from the sliding door body 155.

[0109] The guide body 156 has a protrusion that protrudes into the inside of the housing 5, so the protrusion provided on the guide body 156 moves in a straight direction along the guide groove portion 44 which is in the shape of a straight groove provided on the upper side of the second cover 30.

[0110] Therefore, the second movable door 154 moves horizontally using the second drive unit 152 to open and close the upper discharge outlet 36.

[0111] [Front Door]

[0112] Figure 6 This is a top view showing the front door portion 160 according to an embodiment of the present invention. Figure 7 This is a top view showing the closed state of the front door 160 according to an embodiment of the present invention.

[0113] like Figure 6 and Figure 7 As shown, the front door 160 can be modified in various ways within the technical concept of opening and closing the side outlets 24 located on the left and right sides of the housing 5. In one embodiment of the present invention, the front door 160 may include: a front drive unit 162, fixed to the housing 5 and supplying rotational power; and a front movable door 164, connected to the front drive unit 162, which moves by the action of the front drive unit 162, thereby opening and closing the side outlets 24.

[0114] Side exhaust ports 24 are provided on both sides of the first enclosure 20 in the width direction. The side exhaust ports 24 extend vertically and discharge air from the second air supply module 90 and the third air supply module 100 to the front of the housing 5. These side exhaust ports 24 are opened and closed by the front door 160.

[0115] The front drive unit 162 is fixed to the front of the housing 5. A circular gear is provided on the output shaft of the front drive unit 162, and a rack is formed on the front moving door 164 opposite to the circular gear of the front drive unit 162. Therefore, the front drive unit 162 and the front moving door 164 are connected by a rack and pinion, thereby moving linearly.

[0116] [Airflow in an air conditioner]

[0117] If the user changes the operating mode of the air conditioner 1 to indirect airflow, the front door 160 will move and block the side outlet 24 of the unit 5. Furthermore, the first door 140 will move, causing the second sliding door 154, which was blocking the upper outlet 36, to move and thus open the upper outlet 36.

[0118] Since the side outlet 24 of the housing 5 is blocked, the air discharged through the second air supply module 90 and the third air supply module 100 moves to the side of the second air supply module 90 and the third air supply module 100 via the second air separation wall 112 and the third air separation wall 114, and then moves to the upper side of the housing 5.

[0119] After moving to both sides of the second air supply module 90 and the third air supply module 100 in the width direction, the air that has moved to the upper side of the housing 5 moves through the first inner pipe 124 of the auxiliary pipe section 120 to the discharge pipe section 130, and then is discharged in front of the auxiliary pipe section 120 through the discharge outlet 132. At this time, the first movable door 144 for opening and closing the discharge outlet 132 is also in the open state. Therefore, the air discharged through the discharge outlet 132 forms an indirect wind that is guided to be discharged in front of the housing 5 through the first movable door 144.

[0120] Furthermore, the air discharged through the first air supply module 80 moves to the upper inner duct 34 via the first air partition wall 110 and the side air partition wall 116. The air moving upward via the inner duct 34 forms a direct airflow that is expelled towards the front of the housing 5 through the cover blades 40.

[0121] The air discharged from the first air supply module 80 is discharged through the upper discharge port 36, and the air discharged from the second air supply module 90 and the third air supply module 100 flows out through the discharge port 132, which can realize the upper centralized discharge mode.

[0122] Alternatively, the front door 160 actuates to open the side outlet 24 of the box 5, and the first door 140 actuates to block the outlet 132.

[0123] The air expelled from the second air supply module 90 and the third air supply module 100 is discharged to the front of the housing 5 through the side discharge port 24.

[0124] Furthermore, the air discharged through the first air supply module 80 moves to the upper inner duct 34 via the first air partition wall 110 and the side air partition wall 116. The air moving upward through the inner duct 34 forms a direct airflow that is expelled to the front of the housing 5 via the cover blades 40.

[0125] Therefore, the air discharged from the first air supply module 80 to the upper side can form direct airflow that is discharged to the front of the auxiliary duct section 120 through the upper discharge port 36. Furthermore, the air discharged from the other air supply modules, except for the air supply module located at the uppermost side of the air supply module section 70, can form indirect airflow that is discharged to the front of the auxiliary duct section 120 after moving through the auxiliary duct section 120.

[0126] On the other hand, if the front door 160 moves and blocks the side outlet 24, the air discharged from the second air supply module 90 and the third air supply module 100 forms indirect air through the auxiliary pipe section 120, and the air discharged from the first air supply module 80 forms direct air through the upper outlet 36. Therefore, it can provide concentrated upper air supply that is discharged to the upper side of the housing 5.

[0127] The present invention has been described above with reference to the exemplary accompanying drawings. However, the present invention is not limited to the embodiments and drawings described in this specification, and it is obvious to those skilled in the art that various modifications can be made within the scope of the technical concept of the present invention. Furthermore, even if the effects of the structure of the present invention are not explicitly described in the description of the embodiments of the present invention, the effects that can be predicted by the structure should obviously be recognized.
