Description

Technical Field

[0001] This invention relates to the indoor unit of an air conditioner. Background Technology

[0002] An air conditioner is a device that provides a comfortable environment by regulating the temperature, humidity and cleanliness of indoor air. It works by drawing in outside air through an air intake section and then discharging the air, which has been processed by the internal air conditioning unit such as a heat exchanger and filter, into the room through an air exhaust section.

[0003] An air exhaust section can be formed at the front of the air conditioner, and an air conditioning unit such as a heat exchanger and filter can be installed inside for air conditioning and purification. In addition, an air supply device can be built in to ensure effective circulation of indoor air.

[0004] In the case of household air conditioners, split-type air conditioners, consisting of an indoor unit and an outdoor unit, are typically used. The indoor unit includes an indoor heat exchanger that directly cools or heats the indoor air and an indoor air supply device. The outdoor unit has an outdoor heat exchanger, an air supply device, and a compressor that circulates the refrigerant. The indoor and outdoor units are connected by refrigerant pipes to cool, heat, or dehumidify the indoor air.

[0005] As indoor units of the aforementioned split-type air conditioners, depending on their installation configuration, there are floor-standing indoor units that are installed upright on the indoor floor, wall-mounted indoor units that are hung on the indoor wall, and ceiling-mounted indoor units that are installed on the indoor ceiling.

[0006] Korean Patent KR10-1633782, which relates to conventional split-type air conditioners, discloses a structure in which an input / output module is provided on the front panel. Typically, the input / output module, such as a display, is positioned adjacent to the front panel to ensure user visibility and can be electrically connected to the control unit of the indoor unit.

[0007] However, there is a problem that, in addition to needing to attach the front panel to the housing, the display module also needs to be connected independently to the control unit. In particular, even when the front panel is separated from the housing, the electrical connection between the display module and the control unit needs to be maintained, which raises the possibility of safety issues such as tension, breakage, or damage to the wiring and connectors.

[0008] Therefore, as a solution to improve maintainability and safety, a configuration can be established where the display module is appropriately positioned on the indoor unit's panel, and the display module is automatically wired to and disconnected from the control unit through the joining and disconnection of the panels. This allows users to easily establish an electrical connection between the display module and the control unit simply by removing and installing the front panel without requiring additional wiring work, reducing assembly errors during maintenance.

[0009] Additionally, a guide section is required to prevent misassembly during the insertion of the connector into the socket connecting the display module and the control unit. This prevents damage caused by incorrect connection of the socket and connector, and improves the structural safety of the indoor unit.

[0010] Meanwhile, appropriately configuring limit switches and other devices to sense the connection status of connectors, and enabling the verification of accurate connection of the display module, are crucial elements for the simple design and safety assurance of the indoor unit. Therefore, improving the maintainability of air conditioners and preventing misassembly and electrical problems that may occur during the assembly and use of the indoor unit are important issues that need to be addressed in this technical field.

The blades 32 are formed in a radial wing shape on the fan hub 31.

[0089] The aforementioned air supply motor 33 serves as the motor that drives the aforementioned air supply fan 30, and is connected to the aforementioned fan hub 31 to transmit rotational force.

[0090] The motor bracket 34 supports and fixes the air supply motor 33, and the shock absorber 36 overlaps the motor bracket 34 to prevent vibrations and noise generated when the air supply module 3 is working from being transmitted to the surrounding components.

[0091] It may also include a protective panel 4, which is disposed between the air supply module 30 and the intake port 13 to guide air to the air supply module 30.

[0092] The aforementioned fan 30 can be stored in the fan storage section 41 of the protective panel 4 fixed to the aforementioned housing 1.

[0093] The aforementioned protective panel 4 can guide air to the aforementioned fan 30 through the air flow hole 42 provided in communication with the aforementioned fan storage part 41.

[0094] It may include a fan panel 5, which is disposed in front of the aforementioned air supply fan 30 and fixes the aforementioned air supply module 3 to the aforementioned housing 1.

[0095] A motor mounting surface 53 is formed on the front surface of the fan panel 5 to house the air supply motor 33, and the motor bracket 34 supporting the air supply motor 33 can be fixed to the fan panel 5. The rotation shaft of the air supply motor 33 can pass through the shaft through hole 532 of the fan panel 5 and be connected to the air supply fan 30.

[0096] The fan panel 5 is connected to the protective cover panel 4 so that the air supply module 3 can be firmly fixed to the housing 1.

[0097] The aforementioned air supply module 3 may include a first air supply module 3a and a second air supply module 3b disposed below the first air supply module 3a. In this case, the first air supply module 3a and the second air supply module 3b may be fixed by a protective cover panel 4 and a fan panel 5.

[0098] The first fan 30a of the first air supply module 3a and the second fan 30b of the second air supply module 3b are arranged vertically and housed in the protective panel 4. The fan panel 5 is formed in a shape that extends in a long strip along the vertical direction with a shaft through hole 532 that is connected to the shaft through hole 311 of the first fan 30a and the second fan 30b.

[0103] Taking into account the average height of users, the display unit 2d is positioned within the normal field of vision. As an embodiment of the present invention, the display unit 2d may be positioned offset towards the upper side of the front panel.

[0104] The display unit 8, which is positioned opposite the display unit 2d, may also be positioned on the upper side of the air duct cover 6.

[0105] In this case, the first air supply module 3a and a portion of the display unit 8 may overlap in the front-to-back direction. Therefore, the shock absorber 36, which prevents the transmission of vibrations to the display unit 8 when the air supply module 3a is operating, may be provided only in the first air supply module 3a.

[0106] The lower housing 12 is located below the upper housing 11 and can support the indoor unit 100.

[0113] As an embodiment of the present invention, the joint between the upper housing 11 and the lower housing 12 is positioned higher than the joint between the front panel 2 and the base panel 7.

[0114] In this case, even if an external impact is applied to the indoor unit 100, the impact is dispersed and not concentrated at a certain point, thereby enhancing the strength of the indoor unit 100.

[0115] Figure 3 and Figure 4 An example of the aforementioned front panel 2 is shown. Figure 3 The front surface of the aforementioned front panel 2 is shown. Figure 4 A rear perspective view of the aforementioned front panel 2 is shown.

[0116] The aforementioned front panel 2 is formed into a panel shape that extends vertically in a manner that covers the front of the aforementioned first air supply module 3a and the aforementioned second air supply module 3b.

[0117] The front panel 2 has multiple outlets 28, which are located on both sides of the front panel 3 in the width direction. The outlets 28 are formed in an elliptical shape with a major axis in the vertical direction.

[0118] The aforementioned front panel 2 is formed as a curved surface protruding forward, and the aforementioned outlet 28 is formed on the curved surface so that the air discharge direction of the aforementioned outlet 28 not only faces forward, but also diffuses to the side in a wide range.

[0119] The structure of the front panel 2 is divided into an upper surface 2b, a bottom surface 2a, a connecting surface 2c that connects the upper surface 2b and the bottom surface 2a and forms a curved surface with the outlet 28, and a flange portion 29 that extends further downward than the bottom surface 2a, which will be described later.

[0120] The aforementioned upper surface 2b is supported upward by the aforementioned housing 1.

[0121] As an embodiment of the present invention, a guide groove 24 may be provided on the upper surface 2b, which is supported from below by the protective panel 4 and into which the guide protrusion 40 provided on the protective panel 4 is inserted. Therefore, the front panel 2 can be guided to the position where it is supported and engaged by the housing 1.

[0122] When the aforementioned elastic protrusion 44 separates from the aforementioned fixed protrusion 25 of the aforementioned front panel 2, the aforementioned front panel 2 can move upward relative to the aforementioned housing 1 and separate.

[0123] When the elastic protrusion 44 is separated from the fixed protrusion 25 of the front panel 2, the guide protrusion 40 of the support end 4d of the cover panel 4 can be separated from the guide groove 24 of the upper surface 2b of the front panel 2.

[0124] A docking part 20, supported by the housing 1 and connected to the control unit 9, may be provided on the bottom surface 2a.

[0135] The aforementioned fixing protrusion 25 can be disposed at the side end of the aforementioned connecting surface 2c. Therefore, since the aforementioned connecting surface 2c is formed as a curved surface protruding forward, the aforementioned fixing protrusion 25 can be disposed rearward than the aforementioned duct cover 6.

[0136] The bottom surface of the fixed protrusion 25 supports the floating anti-rib 66 of the air duct cover 6 from above, and supports the rear end of the floating anti-rib 66 from the front, thereby preventing the floating anti-rib 66 from moving backward.

[0137] The aforementioned fixed protrusion 25 is provided with a groove that opens to the rear, thereby accommodating the elastic protrusion 44 of the aforementioned protective panel 4 as described later.

[0138] The aforementioned fixed protrusions 25 are provided in multiple ways and are arranged aligned vertically at both ends of the front panel 2.

[0139] An insertion rib 27 that connects to the air duct cover 6 may be provided on the aforementioned connecting surface 2c.

[0140] The aforementioned insertion rib 27 extends toward the aforementioned air duct cover 6, and the extended end can be bent downwards. Therefore, it is inserted into the insertion slot 651 of the aforementioned air duct cover 6, which is formed in the shape of a slot, and is supported upwards.

[0141] The aforementioned insertion rib 27 is disposed between the centerline of the width direction of the aforementioned connecting surface 2c and the aforementioned outlet 28, and is formed by extending in the vertical direction on one side and the other side respectively, with the width direction of the aforementioned connecting surface 2c as a reference.

[0142] The aforementioned insertion rib 27 and the aforementioned fixing protrusion 25 sandwich the outlet in the middle, thereby enabling the aforementioned air duct cover 6 and the aforementioned front panel 2 to be joined.

[0143] The front surface of the aforementioned flange portion 29 can be shielded by the aforementioned base panel 7.

[0144] A base fixing groove 292 may be provided on the flange portion 29, and the front panel bracket 72, which is provided on the base panel 7 and extends toward the rear, may be inserted into and fixed in the base fixing groove 292.

[0145] The aforementioned base fixing grooves 292 are respectively provided on both sides of the aforementioned flange portion 29 in the width direction.

[0146] The flange portion 29 may be provided with a front panel fixing portion 291 for fixing the front panel 2 to the housing 1.

[0147] The aforementioned front panel fixing part 291 is threadedly connected to the aforementioned protective panel 4 to fix the aforementioned front panel 2 to the aforementioned housing 1.

[0148] The aforementioned front panel fixing portion 291 is disposed on the left and right sides respectively, offset from the width direction of the aforementioned flange portion 29. The aforementioned front panel fixing portion 291 is formed closer to the side end of the aforementioned flange portion 29 than the aforementioned base fixing groove 292.

[0149] Figure 5 and Figure 6 An example of the aforementioned duct cover 6 is shown. Figure 5 The front surface of the aforementioned air duct cover 6 is shown. Figure 6 The rear surface of the aforementioned air duct cover 6 is shown.

[0150] The aforementioned duct cover 6 may include: a cover portion 64 for mounting the aforementioned module housing 80, the front surface of which is shielded by the aforementioned front panel 2; a louver portion 60 having louvers 61 disposed on both sides of the cover portion 64 in the width direction to guide air to the aforementioned outlet 28; a connecting portion 65 connecting the aforementioned cover portion 64 and the aforementioned louver portion 60, and being recessed further rearward than the aforementioned louver portion 60 and the aforementioned cover portion 64; and a sealing flange 67 forming the lower end of the aforementioned duct cover 6, which is in close contact with the aforementioned protective panel 4 to prevent air passing through the aforementioned air supply module 30 from leaking downwards from the aforementioned duct cover 6.

[0151] In the aforementioned louver 61, multiple elliptical structures with major axes in the vertical direction corresponding to the shape of the aforementioned outlet 28 are arranged in a concentric circle structure, and ribs for enhancing rigidity may be provided in the direction traversing the aforementioned louver 61.

[0152] The aforementioned air duct cover 6 may include the aforementioned insertion slot 651 that is connected to the aforementioned insertion rib 27 of the aforementioned front panel 2.

[0153] One end of the insertion slot 651 is connected to the cover 64, and the other end extends to contact the louver 60. The insertion rib 27 is inserted into the gap between the insertion slot 651 and the front surface of the connecting part 65 in a direction from the top to the bottom.

[0154] The aforementioned air duct cover 6 may have a front panel connection portion 642 that is connected to the aforementioned air duct connection portion 275 of the aforementioned front panel 2.

[0155] The aforementioned front panel connecting part 642 can be mechanically coupled with the aforementioned front panel 2 to fix the displacement of the aforementioned air duct cover 6.

[0156] The aforementioned front panel connecting portion 642 is provided on the aforementioned cover portion 64 and can be combined with the aforementioned air duct connecting portion 275 after the aforementioned insertion rib 27 is connected to the aforementioned insertion slot 651.

[0157] The cover 64 may be provided with a display section mounting section 641 for mounting the module housing 80 of the display section 8.

[0158] The aforementioned display mounting portion 641 is provided such that a portion of the aforementioned cover portion 64 is recessed rearward, thereby stably fixing the aforementioned display portion 8 to the aforementioned air duct cover 6.

[0159] After the display unit 8 is installed in the display mounting part 641 and the air duct cover 6 is attached to the front panel 2, the recess depth of the display mounting part 641 is formed to a degree that allows the display 81 to contact the rear surface of the front panel 2. Therefore, the amount of light emitted from the display 81 transmitted to the display unit 2d of the front panel 2 can be increased.

[0160] The aforementioned duct cover 6 may be provided with a fan panel insertion rib 68 that is inserted into the duct fixing groove 57 of the fan panel 5 described later.

[0161] The aforementioned fan panel insert rib 68 may be formed to extend from the rear surface of the aforementioned cover 64 toward the aforementioned fan panel 5. Specifically, the aforementioned fan panel insert rib 68 is formed to extend toward the aforementioned fan panel 5 and the extended end is curved downward.

[0162] Therefore, the fan panel insertion rib 68 is formed in the following shape: it is inserted into the air duct fixing groove 57 from the top to the bottom, and is supported upward after insertion.

[0163] Multiple fan panel insert ribs 68 may be provided and formed in a shape in which the two ends of the rear surface of the cover 64 are aligned vertically in the width direction, and can be provided in a position that does not interfere with the display mounting portion 641.

[0164] The aforementioned air duct cover 6 may be provided with a movement prevention rib 66 that interferes with the aforementioned fixed protrusion 25 of the aforementioned front panel 2 and restricts its movement.

[0165] The aforementioned anti-movement rib 66 can be formed as a plate extending outward from both sides of the aforementioned air duct cover 6.

[0166] The aforementioned anti-movement rib 66 is formed in the following shape: it is inserted from the upper side of the aforementioned fixed protrusion 25 in the downward direction and supported upward, and the rear surface is supported forward by the aforementioned fixed protrusion 25, thereby restricting rearward movement.

[0167] Multiple anti-movement ribs 66 are provided, and are arranged in a vertically aligned manner on the edges of both sides of the air duct cover 6.

[0168] The aforementioned duct cover 6 is formed in such a way as to cover the front surface of the aforementioned fan panel 5, so as to prevent the air flowing through the aforementioned fan 30 from leaking between the aforementioned fan panel 5 and the aforementioned duct cover 6.

[0169] If the width of the fan panel 5 is narrower than that of the fan hub 31 of the fan 30 in the width direction, the air discharged through the blades 32 moves through the shaft through hole 311 of the fan hub 31 and the like, which hinders the flow path to the outlet 28. Cold air condenses on the rotating shaft and the like, which may lead to a decrease in the durability of internal components.

[0170] In this case, the aforementioned air duct cover 6 may include a shielding portion 652, which prevents air flowing through the aforementioned air supply fan 30 from flowing between the aforementioned air supply module 3 and the aforementioned cover portion 64 of the aforementioned air duct cover.

[0171] The aforementioned shielding portion 652 can be provided at the connecting portion 65 of the aforementioned duct cover 6 to connect the edges of the aforementioned duct cover 6 and the aforementioned fan hub 31. Therefore, a blockage can be achieved to prevent air discharged through the aforementioned blades 32 from flowing between the aforementioned fan hub 31 and the aforementioned duct cover 6.

[0172] A sealing flange 67 may be provided on the aforementioned air duct cover 6 to prevent air that has passed through the aforementioned air supply module 3 from moving to the outside of the aforementioned air duct cover 6.

[0173] The upper end of the aforementioned duct cover 6 is supported by the aforementioned fan panel 5. The side end of the aforementioned duct cover 6 is positioned further forward than the rear end of the aforementioned front panel 2 and contacts the aforementioned front panel 2 to be sealed. Therefore, the aforementioned sealing flange 67 can be provided at the lower end of the aforementioned duct cover 6.

[0174] The sealing flange 67 is disposed at the lower end of the air duct cover 6 and contacts the fan panel 5, thereby preventing the air discharged from the air supply module 3 from flowing to the outside of the air duct cover 6.

[0175] A protruding surface 69 may be provided at the upper end of the sealing flange 67. The protruding surface 69 extends toward the front panel 2, thereby preventing air from the cover portion 64, the connecting portion 65, and the louver portion 60 of the duct cover 6 from being discharged to the lower part between the front panel and the duct cover.

[0176] A wire harness through hole 691 may be provided on the protruding surface 69 for the wire harness of the display section 8 to pass through.

[0177] Figure 7 This shows the state in which the aforementioned air duct cover 6 is fixed to the aforementioned front panel 2.

[0178] After the aforementioned air duct cover 6 is fixed to the rear surface of the aforementioned front panel 2, it can be stored in the aforementioned housing 1, and can be separated together with the aforementioned front panel 2 when it is separated from the aforementioned housing 1. That is, the aforementioned air duct cover 6 is modular relative to the aforementioned front panel 2, so that it can be disassembled and assembled together with the aforementioned housing 1.

[0179] After the connection of the front panel 2 to the front panel fixing part 291 is released, when the fixing protrusion 25 and the elastic protrusion 44 of the protective panel 4 separate in the front-rear direction, the upper surface 2b of the front panel 2 is supported upward by the supporting end 4d of the protective panel 4, and thus can be separated upward relative to the housing 1.

[0180] The fan panel insertion rib 68 of the aforementioned duct cover 6 is supported upward by engaging downward with the aforementioned duct fixing groove 57 of the aforementioned fan panel 5, and the upper end of the aforementioned duct cover 6 can be supported upward by the aforementioned fan panel 5.

[0181] Therefore, when the front panel 2 is separated upward relative to the housing 1, the air duct cover 6 and the fan panel 5 can be naturally disengaged from each other.

[0182] The front panel connecting portion 642 of the aforementioned air duct cover 6 is mechanically fixed relative to the air duct connecting portion 275 of the aforementioned front panel 2. Therefore, even if the aforementioned front panel 2 is disengaged from the aforementioned housing 1, the aforementioned air duct cover 6 will not separate from the aforementioned front panel 2.

[0183] Compared with the air duct cover 6, the front panel 2 is longer in both the vertical and width directions.

[0184] The outlet 28 of the front panel 2 can be respectively disposed on both sides of the width direction of the front panel 2. The edge of the louver portion 60 of the air duct cover 6 contacts the outlet 28. Therefore, the cover portion 64 and the connecting portion 65 can be disposed between the outlets 28 on both sides.

[0185] That is, the front surfaces of the cover portion 64 and the connecting portion 65 of the aforementioned air duct cover 6 are covered by the aforementioned front panel 2.

[0186] The bottom surface 2a can be positioned lower than the duct cover 6. Therefore, the bottom surface 2a and the duct cover 6 do not interfere with each other, and the connector 82 can easily pass through the bottom surface 2a.

[0187] The flange portion 29 is positioned below the bottom surface 2a and is at least partially covered by the base panel 7. The front panel fixing portion 291 and the base fixing groove 292 may be provided in the covered area.

[0188] The forward movement of the flange 29 is restricted by the base panel 7, thus preventing the front panel 2 from being detached at will.

[0189] The aforementioned front panel fixing part 291 is not exposed to the outer surface of the aforementioned indoor unit 100, thus improving the aesthetics.

[0190] The front panel bracket 72 of the base panel 7 can be fixed to the base fixing groove 292 through the rear surface of the base panel 7, so it is easy to assemble and disassemble. The joint is not exposed, thus improving the overall appearance.

[0191] Figure 8 It shows that it was formed in Figure 7 The state in which the aforementioned insertion slot 651 and the aforementioned insertion rib 27 in region A are combined.

[0192] When the insertion slot 651 of the aforementioned air duct cover 6 moves downward relative to the insertion rib 27 of the aforementioned front panel 2, the connection between them can be separated.

[0193] In order to separate the front panel 2 from the housing 1 by applying an external force upward, the air duct cover 6 attached to the front panel 2 may be lighter than the front panel 2 depending on the material properties or size difference. In this case, it moves upward with a greater acceleration than the front panel 2, thus hindering the release of the insertion rib 27 and the insertion gap 651.

[0194] Figure 9 Show Figure 7 An enlarged view of region B. The rear surface of the aforementioned anti-movement rib 66 of the aforementioned duct cover 6 is supported forward by the aforementioned fixed protrusion 25, and the aforementioned front panel 2 is located on the front surface of the aforementioned anti-movement rib 66, thus preventing the aforementioned duct cover 6 from moving back and forth. Therefore, when the aforementioned fixed protrusion 25 of the aforementioned front panel 2 and the aforementioned elastic protrusion 44 of the aforementioned protective panel 4 are released in the front-back direction, the aforementioned anti-movement rib 66 can be prevented from being released.

[0195] Figure 10 and Figure 11 An example of the aforementioned fan panel 5 is shown. Figure 10 The front surface of the aforementioned fan panel 5 is shown. Figure 11 The rear surface of the aforementioned fan panel 5 is shown.

[0196] The fan panel 5 is disposed between the shield panel 4 and the front panel 2 in such a way that it covers at least a portion of the front surface of the shield panel 4.

[0197] The aforementioned fan panel 5 may include: a fan panel body 50, which is provided to cover the front surface of the aforementioned shield panel 4; a rigid rib 55, which is provided to extend from the front surface of the aforementioned fan panel body 50 in a vertical direction to enhance the rigidity of the aforementioned fan panel 5; an assembly platform 56, which is inserted into the aforementioned shield panel 4; and a fastening tab 52, which is connected to the aforementioned shield panel 4.

[0198] The fan panel 5 may be provided with a motor mounting surface 53 for mounting the air supply motor 33.

[0199] The motor mounting surface 53 is formed by the rearward recess of the fan panel body 50, which can prevent the air supply module 3 from protruding excessively in front of the fan panel 5.

[0200] As described later, the motor mounting surface 53 may include a motor seal 531, which extends along the periphery of the motor mounting surface 53 and is in close contact with the air supply motor 33.

[0201] A shaft through hole 532 for the rotating shaft of the aforementioned air supply motor 33 to pass through may be provided on the aforementioned motor mounting surface 53.

[0202] Motor rigid ribs 533 may be provided on the motor mounting surface 53, extending along the periphery of the through hole 532 toward the edge of the motor mounting surface 53.

[0203] Multiple motor rigid ribs 533 may be provided and arranged radially to enhance the strength of the motor mounting surface 53.

[0204] The aforementioned motor rigid rib 533 is formed in a shape that protrudes further forward than the aforementioned motor mounting surface 53, extending in such a way that one end contacts the aforementioned shaft through hole 532 and the other end contacts the aforementioned motor sealing part 531.

[0205] A bracket fixing part 54 may be provided on the outer edge of the motor mounting surface 53, and the motor bracket 35 of the air supply motor 33, which is fixed to the fan panel 5, is connected to the bracket fixing part 54.

[0206] The aforementioned air supply motor 33 and the aforementioned air supply fan 30 connected to the aforementioned air supply motor 33 are always fixed to the fan panel 5 by the aforementioned motor bracket 35.

[0207] The motor bracket 35 is polygonal, and each vertex of the motor bracket 35 can be fixed to the bracket fixing part 54. As an embodiment of the present invention, the motor bracket 35 is triangular, and the three vertices can be fixed to the bracket fixing part 54.

[0208] The aforementioned connecting clip 52 can be configured to be attached to at least one of the upper and lower ends of the aforementioned fan panel body 50. Therefore, even if the aforementioned fan panel 5 is narrower than the aforementioned protective panel 4 in the width direction, it is easy to connect.

[0209] When the first air supply module 3a and the second air supply module 3b are arranged vertically in the air supply module 3, the protective cover panel 4 and the fan panel 5 can be formed as a single component.

[0210] In this case, the length of the shield panel 4 in the vertical direction is greater than the length in the width direction, and the ratio of the length of the fan panel 5 in the vertical direction to the length in the width direction can be set to be greater than or equal to the shield panel 4.

[0211] The aforementioned rigid rib 55 can extend along the vertical direction of the aforementioned fan panel 5. When it extends along a relatively long vertical direction, it prevents bending or sagging and improves the rigidity enhancement effect.

[0212] Furthermore, the shrinkage rate difference generated during the injection molding and cooling process of the aforementioned fan panel 5 is corrected, thus preventing distortion.

[0213] The aforementioned rigid rib 55 is provided in a forward-facing manner in front of the aforementioned fan panel 5, thereby minimizing interference with the aforementioned protective panel 4.

[0214] The aforementioned rigid rib 55 may include a side end rigid rib 551 extending along the edge of the aforementioned fan panel housing 50. Therefore, the edge of the aforementioned fan panel 5, where shrinkage deformation is greatest and impact or load is concentrated during the injection molding of the aforementioned fan panel 5, can be reinforced.

[0215] When the housing 1 with the fan panel 5 installed is combined with the front panel 2 and the duct cover 6, the side end rigid rib 551 can contact the front panel 2 or the duct cover 6. Therefore, it can prevent the air from the air supply module 3 from moving to the front surface of the fan panel housing 50.

[0216] As an embodiment of the present invention, the aforementioned side end rigid rib 551 contacts the aforementioned air duct cover 6, thereby preventing air leakage between the aforementioned side end rigid rib 551 and the aforementioned air duct cover 6 on both sides, and guiding the airflow to the outside of the aforementioned side end rigid rib 551 of the aforementioned fan panel 5.

[0217] The wiring section (not shown) extending from the aforementioned blower motor 33 is housed inside the aforementioned housing 1 in a manner that is disposed at the lower part of the aforementioned fan panel 5, and extends to connect with the aforementioned control unit 9 that supplies power and control signals.

[0218] The aforementioned wiring section is connected to the aforementioned air supply motor 33 and extends downwards. A first wiring fixing part 552a for fixing the aforementioned wiring section may be provided on the front surface of the aforementioned fan panel 5.

[0219] The first wiring fixing part 552a restricts the wiring part from moving forward, and the wiring part extends between the fan panel housing 50 and the first wiring fixing part 552a.

[0220] The first wiring fixing part 552a is provided on the rigid rib 55.

[0221] The first wiring fixing part 552a extends from the end of the rigid rib 55 along the width direction and guides the wiring part.

[0222] The rigid rib 55 may include a first auxiliary rib 552, which is disposed on one side of the front surface of the fan panel 3 in the width direction and forms the first wiring fixing part 552a.

[0223] The aforementioned first auxiliary rib 552 is composed of a pair of ribs arranged parallel to each other and extending in the vertical direction.

[0224] The aforementioned wiring portion is guided between a pair of ribs of the aforementioned first auxiliary rib 552, and the aforementioned first wiring fixing portion 552a is formed in a shape that restricts the forward movement of the aforementioned wiring portion extending between a pair of ribs.

[0225] The aforementioned rigid rib 55 may include a second auxiliary rib 553, which is composed of a pair of ribs. These ribs are positioned opposite to the first auxiliary rib 552 located on one side of the front surface of the fan panel 5 in the width direction, i.e., on the other side in the width direction, and are arranged parallel to each other, extending vertically. Therefore, adverse conditions caused by the difference in shrinkage rates on one or the other side in the width direction can be prevented during the cooling process after injection molding of the fan panel 5.

[0226] The aforementioned fan panel 5 may include an assembly platform 56, which is formed by bending a portion of the aforementioned fan panel housing 50 forward and is connected to the aforementioned protective panel 4.

[0227] The assembly platform 56 may include a wiring guide 561 that extends along a direction that traverses the first auxiliary rib 552 and does not overlap with the first auxiliary rib 552.

[0228] The wiring guide 561 is configured as a recessed groove for the wiring section to pass through, and is disposed on the side of the fan panel 5 in the width direction where the first auxiliary rib 552 is formed.

[0229] The wiring guide 561 and the first auxiliary rib 552 are arranged to overlap in the vertical direction, which can minimize the bending of the wiring section.

[0230] The aforementioned rigid rib 55 may include a lower end rigid rib 554 disposed at the lower end of the aforementioned fan panel 5.

[0231] An auxiliary fixing part 554a may be provided on the lower end rigid rib 554. The auxiliary fixing part 554a is configured to allow the wiring part to pass through and guide the extension path of the wiring part.

[0232] The aforementioned fan panel 5 may be provided with a duct fixing groove 57 that connects to the aforementioned fan panel insertion rib 68 of the aforementioned duct cover 6.

[0233] The aforementioned fan panel insert rib 68 is formed to extend toward the aforementioned fan panel 5 and the extended end is bent downward. The aforementioned fan panel insert rib 68 is inserted into the aforementioned air duct fixing groove 57 from the upper side to the lower side, so that the aforementioned air duct fixing groove 57 can support the aforementioned fan panel insert rib 68 upward.

[0234] The aforementioned front panel 2 separates upward relative to the aforementioned housing 1. When the aforementioned front panel 2 separates, the connection between the aforementioned air duct fixing groove 57 and the aforementioned fan panel insertion rib 58 is naturally released.

[0235] Figure 12 and Figure 13 The state of the aforementioned protective panel 4 is shown. Figure 12 The front surface of the aforementioned protective panel 4 is shown. Figure 13 The rear surface of the aforementioned protective panel 4 is shown.

[0236] The aforementioned protective panel 4 may include: a mounting portion 4a for mounting the aforementioned fan 30; a fixing end portion 4b extending along the periphery of the aforementioned mounting portion 4a and engaging with other components of the aforementioned housing 1; an insertion end portion 4c inserted between the aforementioned base panel 7 and the aforementioned lower housing 12 and connected to the aforementioned front panel 2; and a supporting end portion 4d supporting the aforementioned front panel 2 upwards.

[0237] The aforementioned mounting section 4a may be provided with a fan storage section 41 for mounting the aforementioned fan 30.

[0238] The aforementioned fan housing 41 is formed by a portion of the aforementioned mounting portion 4a being recessed rearward, thereby stably housing the aforementioned fan 30 and preventing the aforementioned fan 30 from protruding excessively in front of the aforementioned protective panel 4.

[0239] An airflow hole 42 may be provided in the center of the aforementioned fan housing 41 to transmit air that has passed through the aforementioned indoor heat exchanger 15 to the aforementioned blower fan 30.

[0240] The aforementioned fan housing 41 is configured with a curved surface recessed from the aforementioned air flow hole 42 toward the edge of the aforementioned fan housing 41, thereby allowing the air moving from the aforementioned air flow hole 42 to diffuse and distribute to the aforementioned blades 32 of the aforementioned fan 30.

[0241] The mounting portion 4a is formed in a shape that is recessed further rearward than the front surface of the cover panel 4, thereby minimizing interference with the fan panel 5 and the like.

[0242] At least a portion of the front surface of the aforementioned mounting portion 4a is covered by the aforementioned fan panel 5.

[0243] An insertion guide 43 may be provided in the mounting section 4a, which protrudes forward so as to be inserted into the assembly platform 56.

[0244] The aforementioned insertion guide 43 can be configured to avoid interference with the aforementioned wiring guide 561 of the aforementioned assembly platform 56.

[0245] As an embodiment of the present invention, the insertion guide 43 is formed to match the shape of the assembly platform 56 in the front-back direction.

[0246] When the air supply module 3 is equipped with the first air supply fan 30a and the second air supply fan 30b, the first air supply fan 30a and the second air supply fan 30b are aligned vertically and housed in the protective cover panel 4.

[0247] The aforementioned insertion guide 43 may be disposed between the aforementioned first fan 30a and the aforementioned second fan 30b.

[0248] An elastic protrusion 44 may be provided at the fixed end 4b, which is inserted into the fixed protrusion 25 of the front panel 2.

[0249] The aforementioned elastic protrusion 44 is inserted into the aforementioned fixed protrusion 25, deforms, and returns to its original shape so that it can be fixed to the aforementioned fixed protrusion 25.

[0250] The aforementioned elastic protrusions 44 are formed protruding forward from both ends of the front surface of the aforementioned protective panel 4, and multiple protrusions may be provided and arranged aligned in the vertical direction.

[0251] A fan panel fixing part 45, which is fixed to the fan panel 5, may be provided at the fixed end 4b.

[0252] The aforementioned fan panel fixing part 45 may be disposed on at least one side of the upper and lower sides of the aforementioned protective panel 4.

[0253] A fixing hook 46 for connecting with the housing 1 is provided on the rear surface of the fixed end 4b of the protective panel 4. Multiple fixing hooks 46 may be provided and are arranged aligned vertically on both sides of the protective panel 4 in the width direction.

[0254] The aforementioned support end 4d is disposed at the upper end of the aforementioned protective panel 4 and supports the aforementioned upper surface 2b of the aforementioned front panel 2 upward.

[0255] A guide protrusion 40 may be provided at the support end 4d, which is inserted into the guide groove 24 of the front panel 2.

[0256] The aforementioned guide protrusion 40 is inserted into the aforementioned guide groove 24 on the aforementioned upper surface 2b, thereby allowing the aforementioned front panel 2 to be supported upward by the aforementioned protective panel 4.

[0257] The insertion end 4c can be positioned lower than the fixing end 4b. Therefore, it can be positioned lower than the joint portion with the fan panel 5, i.e., the fan panel fixing portion 45.

[0258] The front surface of the aforementioned insertion end 4c may not be covered by the aforementioned fan panel 5.

[0259] The aforementioned insertion end 4c may include a second wiring fixing part 45, which is used to guide the wiring part extending downward toward the fan panel 5 to the control part.

[0260] The insertion end 4c may be provided with a groove extending in the direction of the wiring portion to receive the wiring portion, and the second wiring fixing part 45 restricts the forward movement of the wiring portion passing through the insertion end 4c.

[0261] The aforementioned protective panel 4 is provided with the aforementioned docking panel 46, which has the aforementioned wire harness socket 461 connected to the aforementioned control unit 9, and the aforementioned connector 82 can be connected to the aforementioned control unit 9 through the aforementioned wire harness socket 461.

[0262] The aforementioned docking panel 46 is disposed at the aforementioned insertion end 4c and does not interfere with the aforementioned fan panel 5.

[0263] The aforementioned docking panel 46 can be positioned at a location that passes through the aforementioned base panel 7 without exposing the front surface.

[0264] The aforementioned docking panel 46 protrudes forward toward the aforementioned front panel 2, and the aforementioned wire harness socket 461 is disposed on the upper surface of the aforementioned docking panel 46 and can be connected to the aforementioned connector 82 in the vertical direction.

[0265] The aforementioned insertion end 4c may be provided with a front panel connecting part 47 that is mechanically connected to the aforementioned front panel fixing part 291 of the aforementioned front panel 2.

[0266] The connection point between the aforementioned front panel connecting part 47 and the aforementioned front panel fixing part 291 can be shielded from the front by the aforementioned base panel 7, and exposed when the aforementioned base panel 7 is separated from the aforementioned housing 1.

[0267] The insertion end 4c may be provided with a housing connection part 48 that is connected to the housing 1.

[0268] The aforementioned housing connection portion 48 can be connected to at least one of the aforementioned upper housing 11 or the aforementioned lower housing 13.

[0269] The aforementioned housing connection part 48 can be configured to pass through the aforementioned insertion end 4c in the front-rear direction and mechanically engage with the aforementioned housing 1.

[0270] The upper housing 11 and the lower housing 13 overlap behind the housing connecting portion 48, and the housing connecting portion 48 can be connected in a manner that penetrates the entire insertion end 4c, the upper housing 11 and the lower housing 13.

[0271] As an embodiment of the present invention, the lower housing 13 is disposed behind the housing connecting portion 48, and the upper housing 11 is disposed behind the lower housing 13 to achieve the connection between them.

[0278] The aforementioned base panel 7 can be formed as a curved surface that matches the shape of the aforementioned front panel 2 in the vertical direction. Therefore, it can be easily joined to the aforementioned housing 1 through the curved side end, and the joint between the aforementioned base panel 7 and the aforementioned housing 1 is not exposed to the front surface appearance, thereby improving the aesthetics.

[0279] The base panel 7 is configured to cover at least a portion of the front surface of the flange portion 29 of the front panel 2, and the base panel is configured to cover at least a portion of the front surface of the insertion portion 4c of the cover panel 4.

[0280] Therefore, the connection between the panels that are joined together by the flange portion 29 or the insertion portion 4c can be prevented from being exposed to the user from the base panel 7.

[0281] The rear surface of the base panel 7 may be provided with the front panel bracket 72, which is inserted into the base fixing groove 292 of the front panel 2 and connected thereto.

[0282] The aforementioned front panel bracket 72 extends rearward from the rear surface of the aforementioned base panel body 70 and can be inserted into the aforementioned base fixing groove 292 of the aforementioned front panel 2.

[0283] The aforementioned front panel bracket 72 is inserted into the aforementioned base fixing groove 292 and deformed, and then restored to be able to be combined with the aforementioned base fixing groove 292.

[0284] Multiple column mounting ribs 71 that are connected to the lower column 16 may be provided on the rear surface of the base panel body 70.

[0285] The aforementioned column mounting ribs 71 can extend toward the aforementioned lower column 16, and multiple ribs are provided and aligned in the vertical direction.

[0286] The aforementioned column mounting rib 71 can be inserted into and fixed to the base fixing groove 163 of the aforementioned lower column 16.

[0287] The aforementioned column mounting rib 71 can be moved from front to rear to insert into and fix to the aforementioned lower column 16.

[0288] The aforementioned column mounting rib 71 can be inserted into the aforementioned base fixing slot 163 to deform and then be restored and fixed.

[0289] Figure 16 This shows the state in which the base panel 7 is separated from the housing 1.

[0290] The aforementioned base panel 7 can be separated forward relative to the aforementioned housing 1.

[0291] In order to separate the base panel 7, the user can pull the base panel 7 forward relative to the housing 1.

[0292] Pull the base panel 7 forward, and the front panel bracket 72, which is fixed to the base fixing groove 292 of the front panel 2, can be separated forward.

[0293] The aforementioned front panel bracket 72 can extend rearward from the rear surface of the aforementioned base panel body 70 and be fixed through the front surface of the aforementioned front panel 2.

[0294] As described above, the front panel bracket 72 is fixed to the base fixing groove 292 by elastic restoring force, and can be separated by elastic deformation when an external force of a certain magnitude or greater is applied.

[0295] Pulling the base panel 7 forward allows the column mounting rib 71, which is inserted into the base fixing groove 163 of the lower column 16, to be separated.

[0296] The aforementioned column mounting rib 71 extends rearward from the rear surface of the aforementioned base panel body 70 and inserts into the aforementioned lower column 16. When the aforementioned base panel 7 is separated forward, the aforementioned column mounting rib 71 can be separated at the same time.

[0297] When the base panel 7 is separated from the housing 1, the lower storage space 120 is exposed forward, allowing maintenance of the control unit 9 stored in the lower storage space 120.

[0298] When the base panel 7 is separated from the housing 1, the front surface of the flange portion 29 of the front panel 2 can be exposed, thereby exposing the front panel fixing portion 291.

[0299] The aforementioned front panel fixing part 291 extends through the aforementioned flange part 29 in the front-rear direction and can be mechanically coupled to the aforementioned protective panel 4.

[0300] Figure 17 This shows the front panel 2 separated from the housing 1.

[0301] The above Figure 16 When the base panel 7 is separated from the housing 1 and moves forward, the connection between the front panel fixing part 291 and the front panel connecting part 47 of the protective panel 4 can be released.

[0302] When the connection of the aforementioned front panel fixing part 291 is separated, the aforementioned elastic protrusion 44 inserted into the aforementioned fixing protrusion 25 can be released.

[0303] The elastic protrusion 44 protrudes forward from the front surface of the protective panel 4 and is fixed to the fixed protrusion 25 by elastic force. Therefore, when a certain external force is applied to the front panel 2, the connection between the elastic protrusion 44 and the fixed protrusion 25 can be released.

[0304] The protrusion displacement of the elastic protrusion 44 is very small relative to the length of the front panel 2 in the front-rear direction. Therefore, the connection between the elastic protrusion 44 and the fixed protrusion 25 can be released simply by slightly lifting the front panel 2 forward.

[0305] After the elastic protrusion 44 and the fixed protrusion 25 are disengaged, the front panel 2 can be separated upward relative to the housing 1.

[0306] When the front panel 2 moves upward, the contact between the upper surface 2b of the front panel 2 and the support end 4d of the protective panel 4 can be released, and the guide protrusion 40 can be separated from the guide groove 24.

[0307] When the front panel 2 is separated from the housing 1, the air duct cover 6 installed on the rear surface of the front panel 2 can be separated from the front panel 2 together through the front panel connecting part 642 that is mechanically connected to the front panel 2, the floating anti rib 66 that is fixed to the front panel 2 at its side end to prevent it from moving backward, and the insertion rib 27 that is combined with the insertion slot 651.

[0308] When the front panel 2 is separated from the housing 1, the fan panel 5 can be exposed.

[0309] The fan panel 5 may be narrower than the width of the housing 1 in the width direction, and the length of the fan panel 5 in the width direction may be narrower than the protective panel 4.

[0310] Therefore, the fan panel 5 can be fixed to the cover panel 4 or the housing 1 by the connecting buckle 52 provided at at least one of the upper and lower ends of the fan panel 5, without obstructing the flow of air through the air supply module 30.

[0311] The length of the fan panel 5 in the width direction is shorter than the length of the fan 30 in the width direction.

[0312] Therefore, when the front panel 2 is separated from the housing 1, the fan 30 can be exposed between the side end of the fan panel 5 and the side end of the protective panel 4.

[0313] The rotation shaft of the aforementioned air supply motor 33 passes through the aforementioned fan panel 5. Therefore, if the aforementioned air supply fan 30 is fixed to the center side in the width direction of the aforementioned housing 1, the aforementioned fan panel 5 can also be concentrated to the center side in the width direction of the aforementioned cover panel 4 in order to stably fix the aforementioned air supply motor 33. In this case, the aforementioned air supply fan 30 can be exposed to the outer sides of both ends of the aforementioned fan panel 5.

[0314] With the front panel 2 separated, the user can approach the blower fan 30, which is exposed on the outside of the side end of the fan panel 5, to perform maintenance or clean the blower fan 30.

[0315] Previously, the fan panel 5 and the air duct cover 6 were integrated, which required the louver 61 and the air supply motor 33 to be installed on one panel. Therefore, it was difficult to expose the air supply fan 30 to the outside of the fan panel 5. In order to access the air supply fan 30, the user had to disconnect the air supply motor 33 and other electrical components. Therefore, it was practically impossible to access the structure of the air supply fan 30.

[0316] However, due to the characteristics of the air conditioner 100, the continuous circulation of external and internal air makes it easy for dust and other foreign objects to accumulate on the blower fan 30, which can cause hygiene problems.

[0317] According to an embodiment of the present invention, the fan 30 can be accessed simply by separating the front panel 2, making it easy to clean the fan 30 and thus solving the above-mentioned problem.

[0318] Figure 18 (a) shows a portion of the bottom surface 2a and the flange portion 29 of the aforementioned front panel 2.

[0319] The aforementioned mating portion 20 may be provided on the aforementioned bottom surface 2a. The aforementioned mating portion 20 may be provided with the aforementioned connector through hole 22 for the aforementioned connector 82 to pass through.

[0320] The aforementioned docking portion 20 is supported upward by the aforementioned docking panel 46, the aforementioned connector 82 of the aforementioned docking portion 20 protrudes downward, and the aforementioned wire harness socket 461 of the aforementioned docking panel 46 is provided on the upper surface of the aforementioned docking panel 46 so that the aforementioned connector 82 is inserted downward.

[0321] The aforementioned front panel 2 is joined to the aforementioned housing 1 from the top to the bottom.

[0322] The joining direction of the aforementioned front panel 2 and the aforementioned housing 1 can be the same as the wiring direction of the aforementioned wiring harness and the aforementioned control unit 9.

[0323] When the guide protrusion 40 of the support end 4d of the protective panel 4 is inserted into the guide groove 24 of the upper surface 2b of the front panel 2, and the elastic protrusion 44 is inserted into the fixing protrusion 25 of the front panel 2, the front panel 2 moves downward relative to the housing 1 and is engaged.

[0324] When the front panel 2 is attached to the housing 1, the docking part 20 can be installed onto the docking panel 46.

[0325] The connector 82 is inserted into the wiring harness socket 461 in the same direction as the front panel 2 and the protective panel 4, so that the wiring is automatically connected when the front panel 2 is attached to the housing 1.

[0326] The aforementioned docking portion 20 may be provided with a docking guide portion 21, which is disposed in an manner that interferes with the aforementioned docking panel 46 and guides the connector 82 and the wire harness socket 461 to the correct position for engagement.

[0327] The aforementioned connecting guide 21 may be provided to protrude downwards so as to interfere with the side of the aforementioned docking panel 46.

[0328] Before the connector 82 is inserted into the wire harness socket 461, the engagement guide 21 can interfere with the side of the mating panel 46 and slide downwards. Therefore, poor connection of the connector 82 can be prevented, and structural damage caused by forced insertion can be prevented.

[0329] The aforementioned docking panel 46 may be provided with a limit switch 462 for sensing whether the aforementioned connector 82 is connected to the aforementioned wire harness socket 461, and the aforementioned docking portion 20 may be provided with a switch pin 222 extending in the protruding direction of the aforementioned connector 82 and used to activate the aforementioned limit switch 462.

[0330] The aforementioned switch pins 222 can be respectively disposed in the left and right directions of the aforementioned connector 82 to sense whether the aforementioned connector 82 is correctly connected.

[0331] The aforementioned engagement guide 21 protrudes downwards from the bottom surface 2a beyond the switch pin 222, thereby preventing interference with the mating panel 46 before the switch pin 222 actuates the limit switch 462. Therefore, it guides the switch pin 222 to the correct engagement position, preventing structural damage.

[0332] The aforementioned engagement guide 21 protrudes downwards from the bottom surface 2a beyond the connector 82, thereby preventing interference with the mating panel 46 before the connector 82 is engaged with the wire harness socket 461. This guides the connector 82 to the correct engagement position.

[0333] The connector through hole 22 may be provided for the connector 82 to pass through, and a connector stop 221 may be provided in the connector through hole 22 to extend toward the connector 82 in a manner that restricts the movement of the connector 82.

[0334] The connector stop 221 supports the connector 82 upwards, thereby preventing the connector 82 from protruding excessively or drooping from the front panel 2.

[0335] Figure 18 (b) includes the aforementioned docking panel 46 disposed on the aforementioned protective panel 46.

[0336] The aforementioned docking panel 46 is provided protruding forward and is disposed behind the aforementioned base panel 7, and is disposed within the space formed by the aforementioned base panel 7 and the aforementioned lower housing 13.

[0337] The aforementioned docking portion 20 contacts the upper surface of the aforementioned docking panel 46, and the aforementioned docking panel 46 can support the aforementioned docking portion 20 upwards.

[0338] The aforementioned docking panel 46 may be formed into a hexahedral shape protruding forward from the aforementioned insertion end 4c and having two side surfaces. The aforementioned engagement guide 21 may slide on the aforementioned two side surfaces and guide the position of the aforementioned docking part 20.

[0339] The upper surface of the aforementioned docking panel 46 may be provided with the aforementioned wire harness socket 461 for the aforementioned connector 82 to be inserted.

[0340] The limit switch 462, into which the switch pin 222 is inserted, may be provided on the upper surface of the aforementioned docking panel 46.

[0341] As described above, the coupling guide 21 protrudes further downward than the connector 82, so that the connector 82 can be connected to the wire harness socket 461 after interference occurs between the coupling guide 21 and the mating panel 46.

[0342] As described above, the connecting guide 21 protrudes further downward than the switch pin 222, so that after the connecting guide 21 and the docking panel 46 interfere with each other, the switch pin 222 can cause the limit switch 462 to operate.

[0343] Figure 19 The process of joining the aforementioned docking part 20 and the aforementioned docking panel 46 is shown.

[0344] Figure 19 (a) shows the state in which the above-mentioned connecting guide 21 interferes with the above-mentioned docking panel 46.

[0345] The aforementioned docking portion 20 can move downwards to contact the upper surface of the aforementioned docking panel 46. Therefore, when the aforementioned front panel 2 moves from the top to the bottom and is fixed to the aforementioned housing 1, the aforementioned docking panel 46 and the aforementioned docking portion 20 can naturally come into contact.

[0346] The aforementioned connecting guide 21 protrudes further downward than the aforementioned connector 82 and the aforementioned switch pin 222, thereby allowing it to slide on the side of the aforementioned mating panel 46 and guiding the aforementioned mating part 20 to the correct installation position.

[0347] After the connecting guide 21 guides the installation position of the docking part 20, the switch pin 222 and the connector 82 are respectively inserted into the limit switch 462 and the wire harness socket 461, thus preventing mechanical damage that may occur if the connector 82 and the switch pin 222 are not in perpendicular contact with the docking panel 46.

[0348] The connector 82 may be provided on the central side of the docking portion 20 in the width direction, and the switch pin 222 may be provided on both sides of the connector 82 in the width direction.

[0349] Therefore, when the connector 82 is inserted into the correct position of the wire harness socket 461, the limit switches 462 provided on both sides of the wire harness socket 461 will activate to sense the correct connection of the connector 82.

[0350] Figure 19 (b) shows the state in which the docking part 20 and the docking panel 46 are in complete contact.

[0351] When the mating part 20 is in full contact with the upper surface of the mating panel 46, the connector 82 is fully engaged with the wire harness socket 461, and the limit switch 462 can sense the full engagement of the connector 82.

[0352] The limit switch 462 is designed to operate after the connector 82 is engaged with the wire harness socket 461, thereby preventing the limit switch 462 from operating in an incompletely engaged state and preventing safety accidents such as current flow in an incompletely engaged state of the connector 82.

[0353] In this invention, the direction in which the front panel 2 is attached to the housing 1 and the direction in which the connector 82 is connected to the wiring harness socket 461 are set to be the same. Therefore, by simply attaching the front panel 2 to the housing 1, power can be supplied to and controlled for the display unit 8, thereby improving assembly convenience.

[0354] Figure 20This shows the state of the upper housing 11 exposed in front after the front panel 2 is separated.

[0355] The aforementioned fan panel 5 can be fixed to the front surface of the aforementioned protective panel 4 by means of the aforementioned connecting buckle 52 provided at at least one of the upper and lower ends.

[0356] Compared to the front surface of the aforementioned shield panel 4, the aforementioned fan panel 5 is narrower in the width direction.

[0357] The aforementioned air supply motor 33 can be fixed in front of the aforementioned fan panel 5, and the aforementioned air supply motor 33 causes the aforementioned air supply fan 30 mounted on the aforementioned protective panel 4 to rotate.

[0358] The aforementioned air supply motor 33 causes the aforementioned air supply fan 30 to rotate through the aforementioned shaft through hole 532 that passes through the aforementioned fan panel 5.

[0359] To improve the airflow efficiency of the aforementioned fan 30 and to ensure the size of the aforementioned fan 30, the aforementioned fan 30 may be installed at the center in the width direction of the aforementioned cover panel 4, and the aforementioned fan panel 5, which passes through the center of the aforementioned fan 30, may be disposed on the central side in the width direction of the aforementioned cover panel 4.

[0360] At least a portion of the aforementioned fan 30 may be exposed between the outer side of the side end of the aforementioned fan panel 5 and the side end of the aforementioned protective panel 4.

[0361] The aforementioned fan 30 may include the aforementioned fan hub 31 into which a rotating shaft is inserted and the aforementioned blades 32 arranged radially along the periphery of the aforementioned fan hub.

[0362] At least a portion of the blades 32 are exposed between the outer side of the side end of the fan panel 5 and the side end of the protective panel 4. Therefore, the user can clean the blades 32 through the gap.

[0363] The distance between the side end of the fan panel 5 and the side end of the protective panel 4 can be longer than the length of the blades 32 extending from the fan hub 31. Therefore, when the front panel 2 is separated, the exposed area of ​​the blades 32 is maximized, thereby improving cleanliness for the user.

[0364] When the length of the blade 32 is less than the distance between the side end of the fan panel 5 and the side end of the protective panel 4, a portion of the fan hub 31 may protrude to the outside of the side end of the fan panel 5. The fan hub 31 protruding to the outside of the side end of the fan panel 5 is sealed at the edge by the shielding portion 652 of the duct cover 6, thereby preventing it from receiving air from the blade 32.

[0365] The length of the aforementioned protective panel 4 in the width direction is almost the same as the length of the aforementioned housing 1 in the width direction.

[0366] The length of the fan panel 5 in the width direction can be less than half the length of the housing 1 in the width direction. Therefore, the area of ​​the blades 32 exposed on the outer side of the side end of the fan panel 5 is increased, thereby improving the user's cleaning convenience.

[0367] As an embodiment of the present invention, the fan panel 5 may be formed to be approximately one-third the length of the housing 1 in the width direction. Therefore, while stably fixing the air supply motor 33, the area of ​​the blades 32 exposed on the open surface 10 of the housing 1 can be ensured.

[0368] A motor bracket 34 for fixing the air supply motor 33 to the fan panel 5 may be provided on the front surface of the fan panel 5.

[0369] The aforementioned fan 30 is composed of the aforementioned first fan 30a and the aforementioned second fan 30b, and they are aligned vertically. In this case, the length of the fan panel 5 in the vertical direction is relatively larger than its length in the horizontal direction, thus increasing its strength through the aforementioned rigid ribs 55.

[0370] When the first fan 30a and the second fan 30b are aligned vertically, the display unit 8 can be positioned in front of the first fan 30a located at the top so that it is within the normal user's field of vision.

[0371] When the display unit 8 is located in front of the first air supply fan 30a, in order to prevent the durability of the display unit 8 from decreasing due to the operation of the first air supply module 3a, the shock-absorbing plate 36 may be provided on the front surface of the motor bracket 34 of the first air supply module 3a.

[0372] The aforementioned indoor heat exchanger 15 can be housed inside the upper casing 11. In order to maximize the heat exchange efficiency of the indoor heat exchanger 15, the height of the indoor heat exchanger 15 can be almost the same as the height of the upper casing 11.

[0373] In order to smoothly exhaust the air after heat exchange in the indoor heat exchanger 15, the air supply module 3 can cover the front surface of the upper housing 11, so the insertion end 4c of the cover panel 4 can be disposed on the outside of the upper housing 11.

[0374] The aforementioned fan panel 5 can extend from the upper end of the aforementioned mounting portion 4a of the aforementioned protective panel 4 to the lower end and be fixed to the aforementioned fixing portion 4b.

[0375] The aforementioned fan panel 5 may not overlap with the aforementioned support end 4d and the aforementioned insertion end 4c of the aforementioned protective panel 4.

[0376] The aforementioned fan panel 5 can be fixed to the aforementioned fixing part 4b of the aforementioned protective panel 4 via the aforementioned connecting buckle 52.

[0377] The aforementioned connecting clips 52 can be provided at the upper and lower ends of the aforementioned fan panel 5. Therefore, the aforementioned fan panel 5 can be fixed to the aforementioned protective panel 4 without obstructing the flow of air discharged to both sides of the side end of the aforementioned fan panel 5.

[0378] Figure 21 An example of the aforementioned lower housing 12 is shown.

[0379] A separation partition 121 may be provided on the upper part of the lower housing 12 to divide the upper storage space 110 and the lower storage space 120.

[0380] The upper surface of the aforementioned separation partition 121 is provided with components such as the aforementioned indoor heat exchanger 15, which are housed in the aforementioned upper storage space 110, and can be stably configured.

[0381] The lower housing may be provided with a fixed connection portion 121a that is fixed to the housing connection portion 48 of the protective panel 4.

[0382] The aforementioned housing connection part 48 is mechanically connected to the aforementioned fixed connection part 121a and the aforementioned upper housing 11, thereby improving the structural safety of the aforementioned indoor unit 100.

[0383] At least a portion of the upper housing 11 is disposed behind the aforementioned fixed connection portion 121a and can overlap in the front-rear direction. Therefore, the protective panel 4, the upper housing 11, and the lower housing 12 can be easily fixed by the front-rear connection of the housing connection portion 48.

[0384] The lower housing 12 may be provided with the lower column 16.

[0385] The aforementioned lower support columns 16 may be disposed on both sides of the lower housing 12 in the width direction. The aforementioned lower support columns 16 may include the aforementioned first support column 161 disposed on one side of the lower housing 12 in the width direction and the aforementioned second support column 162 disposed on the other side in the width direction.

[0386] The first column 161 and the second column 162 are respectively fixed to the column connecting part 49 of the protective panel 4 and can support the protective panel 4 upward.

[0387] The lower housing 12 may be provided with a column fixing part 122 for fixing the lower column 16 to the lower housing 12.

[0388] The lower column 16 may be provided with a base fixing groove 163 into which the column mounting rib 71 of the base panel 7 is inserted.

[0389] The aforementioned column mounting rib 771 can extend rearward from the rear surface of the aforementioned base panel body 70 and be inserted into the aforementioned base fixing groove 163. Therefore, when the aforementioned base panel 7 moves forward and separates from the aforementioned housing 1, the connection between the aforementioned base fixing groove 163 and the aforementioned column mounting rib 771 can be released.

[0390] The control unit 9 can be housed within the lower storage space 120. The control unit 9 can control the heat exchanger, display unit 8, fan motor 33, etc. of the air conditioner and transmit electrical signals. The control unit 9 can be shaped as an electrical enclosure that houses the circuit elements and electronic components that control the air conditioner and is mounted on the rear surface of the lower housing 12.

[0391] Figure 22 The airflow path through the indoor heat exchanger 15 in the indoor unit 100 is shown.

[0392] Air drawn in through the inlet 13 is delivered to the fan 30 housed in the cover panel 4, and the air passing through the fan 30 can be discharged between the outer side of the fan panel 5 and the side of the cover panel 4.

[0393] Air discharged between the outer side of the fan panel 5 and the side of the cover panel 4 can be discharged to the outlet 28 through the louver 61.

[0394] Air passing through the intake 13 of the upper housing 11 exchanges heat with the indoor heat exchanger 15 and flows to the exhaust fan 30 through the airflow hole 42 of the protective panel 4.

[0395] The aforementioned fan 30 rotates in one direction to guide the air that has passed through the aforementioned indoor heat exchanger 15 to the aforementioned air flow hole 42.

[0396] The aforementioned protective panel 4 is provided with a fan storage part 41 for storing the aforementioned fan 30. The fan storage part 41 is formed as a concave surface recessed along the periphery of the aforementioned airflow hole 42, thereby preventing the aforementioned fan 30 from protruding forward excessively.

[0397] The aforementioned fan housing 41 can be formed as a space that widens forward from the aforementioned airflow hole 42 and is formed as a curved surface, thereby allowing air to flow evenly throughout the aforementioned fan 30.

[0398] The air flowing toward the aforementioned blower fan 30 can be guided to move forward through the aforementioned blades 32 of the blower fan 30.

[0399] The aforementioned fan panel 5 may be installed in front of the aforementioned fan.

[0400] Except for the shaft through hole 532 through which the rotating shaft of the air supply motor 33 that causes the air supply fan 30 to rotate passes, the fan panel 5 may be formed as a plate that blocks air in the front-back direction.

[0401] The length of the fan panel 5 in the width direction may be shorter than the length of the fan 30 in the width direction.

[0402] The fan panel 5 is narrower in width direction than the shield panel 4, and the fan 30 can be exposed between the side end of the fan panel 5 and the side end of the shield panel 4.

[0403] The aforementioned air supply motor 33 can be fixed to the front surface of the aforementioned fan panel 5, and can pass through the aforementioned fan panel 5 to connect with the aforementioned fan hub 31 of the aforementioned air supply fan 30 to transmit rotational force.

[0404] To ensure the air delivery efficiency and size of the aforementioned fan 30, the aforementioned fan 30 can be positioned on the central side of the aforementioned cover panel 4. In order to connect the aforementioned fan 30 to the aforementioned air delivery motor 33, the aforementioned fan panel 5 can also be positioned on the central side in the width direction of the aforementioned cover panel 4.

[0405] Therefore, the air passing through the aforementioned fan 30 can move between the two sides of the fan panel 5 and the two sides of the protective panel 4.

[0406] The aforementioned air duct cover 6 may be provided on the front surface of the aforementioned fan panel 5.

[0407] By combining the fan panel insertion rib 68 of the aforementioned duct cover 6 with the duct fixing groove 57 of the aforementioned fan panel 5, the front surface of the aforementioned fan panel 5 can be covered by the aforementioned duct cover 6.

[0408] The aforementioned fan panel insertion rib 68 can be disposed on the rear surface of the aforementioned cover portion 64 of the aforementioned air duct cover 6 and combined with the aforementioned fan panel 5.

[0409] Therefore, the air passing through the aforementioned fan 30 does not move between the front surface of the aforementioned fan panel 5 and the aforementioned duct cover 6.

[0410] The front surface of the fan panel 5 is covered by the cover 64 and the connecting part 65, and the fan panel 5 does not overlap with the louver part 60 of the air duct cover 6 in the front-back direction.

[0411] The connecting portion 65 is provided with a shielding portion 652 that surrounds the fan hub 31 that is exposed to the side end of the fan panel 5, thereby blocking air from flowing into the space between the front surface of the fan panel 5 and the air duct cover 6.

[0412] Air moving in front of the aforementioned fan panel 5 can move toward the aforementioned louver portion 60 of the aforementioned duct cover 6.

[0413] The aforementioned louvered portion 60 may be disposed between the two ends of the aforementioned protective cover panel 4 and the two ends of the aforementioned fan panel 5.

[0414] The louvered portion 60 of the aforementioned air duct cover 6 can contact the lateral edge of the mounting portion 6a of the aforementioned protective panel 4.

[0415] The connecting portion 65 can contact both ends of the fan panel 5, and one end of the louver portion 60 can contact the side end of the mounting portion 4a.

[0416] The aforementioned louvered section 60 may be provided in two parts, which are offset from the two sides of the aforementioned housing 1 in the width direction.

[0417] The louver 61 of the louver section 60 can be formed as a plurality of ellipses with a major axis extending in the vertical direction arranged in a concentric circle shape.

[0418] The side ends of the louvered portions 60 on both sides, away from the center in the width direction of the housing 1, can contact the side ends of the mounting portions 4a.

[0419] The edge of the aforementioned louvered portion 60 may contact the edge of the aforementioned outlet 28 of the aforementioned front panel 2.

[0420] The air guided to the louver section 60 is discharged to the outside of the housing 1 through the outlet 28.

[0421] The aforementioned outlet 28 and the aforementioned louver section 60 are respectively shaped into an ellipse with a major axis in the vertical direction, and can be respectively set on both sides of the width direction of the aforementioned front panel 2.

[0422] The insertion slot 651, which fixes the air duct cover 6 to the rear surface of the front panel 2, can be provided in front of the connecting part 65.

[0423] The front surfaces of the cover portion 64 and the connecting portion 65 of the aforementioned air duct cover 6 can be shielded by the connecting surface 2c of the aforementioned front panel 2.

[0424] The edge of the aforementioned louvered portion 60 contacts the edge of the aforementioned outlet 28, thereby preventing air from flowing between the front surface of the aforementioned connecting portion 65 and the aforementioned cover portion 64 and the aforementioned front panel 2.

[0425] The aforementioned front panel 2 is configured as a curved structure with the center in the width direction as a reference and the left and right sides gradually receding backward along the width direction. The aforementioned outlet 28 is formed on the aforementioned curved surface so that the air passing through the aforementioned air supply module 30 can be discharged to the front and side of the aforementioned housing 1.

[0426] Figure 23 , Figure 24 , Figure 25 , Figure 26 The movement path of the air passing through the aforementioned indoor heat exchanger 15 is shown in sequence.

[0427] Referring to the above Figure 23 The figure shows the protective panel 4 to which the air passing through the indoor heat exchanger 15 is first delivered, and the exhaust fan 30 installed on the protective panel 4.

[0428] Based on the rotation direction of the aforementioned blower fan 30 and the angle of the aforementioned blades 32, the airflow through the aforementioned indoor heat exchanger 15 moves forward, thereby generating a pressure difference between the front and rear with the aforementioned blower fan 30 as a reference, which can maintain the airflow.

[0429] The aforementioned fan 30 may include the aforementioned first fan 30a disposed at the upper part and the aforementioned second fan 30b disposed at the lower part.

[0430] An insertion end 4c may be provided between the first fan 30a and the second fan 30b, which is inserted into the assembly platform 56 of the fan panel 5 and connected to the fan panel 5.

[0431] The aforementioned insertion end 4c protrudes forward and engages with the aforementioned fan panel 5, thus ensuring that the air discharged by the aforementioned first fan 30a and the air discharged by the aforementioned second fan 30b do not mix with each other and maintain a certain flow.

[0432] In order to ensure the air volume of the aforementioned fan 30, the aforementioned fan 30 is made as large as possible without interfering with the periphery of the aforementioned mounting part 4a.

[0433] The width of the fan housing 41 in the width direction is the same as the width of the mounting part 4a in the width direction, and the air discharged from the fan 30 can be discharged in the entire width direction of the mounting part 4a.

[0434] The portion of the fan housing 41 located around the mounting portion 4a can contact the louver portion 60 of the duct cover 6.

[0435] Reference Figure 24 The figure shows that the air passing through the aforementioned fan 30 is discharged between the outer side of the side end of the aforementioned fan panel 5 and the edge of the aforementioned mounting portion 4a.

[0436] The aforementioned fan panel 5 can be formed as a plate that crosses the airflow moving in the front-to-back direction.

[0437] The air discharged from the aforementioned fan 30 can move forward. When the aforementioned fan panel 5 is provided in the path of the forward-moving air, it cannot pass through the aforementioned fan panel 5 and instead detours, so as to be discharged towards the end along the rear surface of the aforementioned fan panel 5.

[0438] The upper and lower ends of the fan panel 5 are fixed to the fixed end 4b of the cover panel 4 by the connecting buckle 52. Therefore, when the fan panel 5 is provided in the path of the air discharged from the fan 30, the air can be discharged along the rear surface of the fan panel 5 to the two ends.

[0439] The aforementioned fan housing 41 is recessed further rearward than the aforementioned fixed end 4b, thus ensuring a predetermined distance from the rear surface of the aforementioned fan panel 5, thereby forming the aforementioned detour path of air.

[0440] The length of the fan panel 5 in the width direction is less than half the length of the mounting portion 4a in the width direction of the cover panel 4, thereby ensuring that the width of the edge of the fan panel 5 and the mounting portion 4a in the side direction is above a certain level, so that the air passing through the fan 30 can be smoothly discharged.

[0441] The space between the side end of the fan panel 5 and the edge of the mounting part 4a in the lateral direction is longer than the length of the blade 32, so that the user can easily clean the dust and other foreign objects accumulated on the blade 32 without disassembling the fan panel 5.

[0442] The assembly platform 56 of the fan panel 5 and the insertion guide 43 of the shield panel 4 cut off the airflow flowing in the vertical direction, so that the airflow passing through the first fan 30a and the airflow passing through the second fan 30b are not mixed and are discharged.

[0443] Reference Figure 25 The figure shows the flow path of the air discharged between the fan panel 5 and the shield panel 4 through the duct cover 6.

[0444] The side end of the aforementioned fan panel 5 can contact the aforementioned connecting portion 65 of the aforementioned duct cover 6.

[0445] The portion of the air duct cover 6 in the connecting part 65 is recessed rearward, so it can easily come into contact with the fan panel 5.

[0446] The cover 64, located inside the connecting portion 65, is fixed to the fan panel 5 by the fan panel insertion rib 68, thus ensuring reliable contact between the connecting portion 65 and the fan panel 5.

[0447] The connecting part 65 and the fan panel 5 are in contact on both sides in the left-right direction, which can block the air from moving to the inside of the contact area.

[0448] The upper and lower ends of the aforementioned air duct cover 6 are in contact with the upper and lower ends of the aforementioned fan panel 5, thereby completely blocking air from flowing into the area between the front surface of the aforementioned fan panel 5 and the rear surface of the aforementioned air duct cover 6.

[0449] The aforementioned louvered portion 60 can be disposed on both sides of the aforementioned air duct cover 60, and the aforementioned anti-movement rib 66 can be provided on the outer side of the side end of the aforementioned louvered portion 60.

[0450] The inner ends of the louvered sections 60 on both sides contact the connecting portion 64 and the fan panel 5, thereby guiding the air that has passed through the fan 30 to the louvered sections 60.

[0451] The outer ends and upper and lower ends of the aforementioned louvered sections 60 on both sides contact the edge of the aforementioned mounting section 4a, thereby guiding the air that has passed through the aforementioned fan 30 to the aforementioned louvered sections 60.

[0452] The louvers 61 of the aforementioned louver section 60 can be formed into concentric circles of an ellipse with a major axis in the vertical direction. Therefore, the air passing through the aforementioned louver section 60 is dispersed in a radial or spiral pattern to form a rotating flow, thereby guiding the generation of turbulence, guiding the uniform distribution of air and minimizing pressure loss.

[0453] Figure 26 This shows the state in which air passing through the louvered portion 60 of the aforementioned air duct cover 6 is discharged from the aforementioned outlet 28 of the aforementioned front panel 2.

[0454] As described above, the front panel 2 is formed as a curved structure with the center in the width direction as a reference, and the left and right sides gradually receding backward along the width direction. The outlet 28 is formed on the curved surface so that the air that has passed through the air supply module 30 can be discharged to the front and side of the housing 1.

[0455] The forward peripheral portion 62 of the louver portion 60 contacts the peripheral edge of the outlet 8, thereby preventing air from leaking through the louver portion 60 between the duct cover 6 and the front panel 2, or leaking to the outer ends of the louver portion 60 on both sides, and then leaking to the joint between the front panel 2 and the housing 1.

[0456] After heat exchange, the air will not move to the rear surface of the front panel 2 and the inside of the cover 64 of the air duct cover 6. Therefore, it can prevent condensation from forming on the display section 8 mounted on the cover 64, which would lead to a decrease in function or performance (such as decreased liquid crystal response speed, black level compression, and burn-in).

[0457] The aforementioned outlets 28 are respectively disposed on both sides of the front panel 2 in the width direction, and can be formed into an elliptical shape with a major axis in the vertical direction. Therefore, the air supply area is increased to provide diffused air, and power consumption is reduced as air resistance is decreased, thereby improving energy efficiency.

[0458] Figure 27 The above is shown Figure 26 The cross section A-A'. Below, through the above... Figure 27 The sealing portion between the panels formed along the flow path of the air flowing through the aforementioned fan 30 will be described.

[0459] As described above, the edge portion 280 extending along the edge of the outlet 28 overlaps with the front peripheral portion 62, which is located in front of the louver portion 60 and extends along its periphery. Therefore, the air delivered to the louver 61 is guided to the outlet 28, preventing air passing through the air supply module 3 from leaking to the outside of the louver portion 60.

[0460] Figure 28 (a) shows the above Figure 27 A magnified view of region A. Figure 28 (b) shows the above Figure 27 A magnified view of region B.

[0461] A step is formed on the edge portion 280 of the outlet 28, and the front peripheral portion 62 can be configured to engage with the step on the edge portion 280 of the outlet 28.

[0462] The end of the edge portion 280 of the outlet 28 has a protrusion 282 that protrudes toward the front peripheral portion 62 and forms a step between it and the non-protruding area 281 of the edge portion 280. The front peripheral portion 62 contacts the edge portion 280 including the protrusion 282 and the non-protruding portion 281, thereby preventing air from leaking between the outlet 28 and the louver portion 60.

[0463] The front panel 2 may be provided with an air duct stop 283, which extends toward the air duct cover 6 to prevent the movement of the front peripheral portion 62.

[0464] The aforementioned air duct stop 283 can restrict the movement of the aforementioned front peripheral portion 62 that engages with the aforementioned edge portion 280.

[0465] The aforementioned air duct stop portion 283 is formed in the opposite direction to the aforementioned protruding portion 282 based on the aforementioned non-protruding portion 281, and contacts the aforementioned front peripheral portion 62, thereby preventing the aforementioned front peripheral portion 62 from detaching from the aforementioned edge portion 280.

[0466] The aforementioned air duct cover 6 may be provided with an overlapping stop portion 621 extending toward the aforementioned front panel 2.

[0467] The aforementioned air duct stop 283 is inserted between the aforementioned front peripheral portion 62 and the aforementioned overlapping stop 621 and is thus restricted from moving.

[0468] The aforementioned air duct stop 283 may be provided between the aforementioned overlapping stop 621 and the aforementioned front peripheral portion 62. Therefore, the movement of the aforementioned air duct stop 283 may be restricted by the aforementioned overlapping stop 621.

[0469] Therefore, the step of the aforementioned edge portion 280 and the joint of the aforementioned front peripheral portion 62 are doubly protected by the aforementioned air duct stop portion 283 and the aforementioned overlapping stop portion 621, thereby preventing air leakage to the joint between the aforementioned outlet 28 and the aforementioned louver portion 60.

[0470] Figure 29 The above is shown Figure 27 A magnified view of region C.

[0471] As described above, the edge of the mounting portion 4a, which is formed along the periphery of the cover panel 4 on which the fan 30 is mounted, overlaps with the rear peripheral portion 63, which is formed along the periphery of the rear surface of the louver portion 60.

[0472] The edge of the mounting portion 4a is configured to contact the rear peripheral portion 63, thereby guiding the air passing through the cover panel 4 to the louver 61 and preventing the air passing through the cover panel 4 from leaking to the outside of the louver portion 60.

[0473] A step is formed in the rear periphery 63, and the edge of the mounting part 4a is formed by overlapping the step in the rear periphery 63 of the louver 61.

[0474] The edge of the aforementioned mounting portion 4a may extend forward.

[0475] The rear periphery 63 of the aforementioned louver portion 60 may include a first extension 631 extending rearward along the edge of the aforementioned mounting portion 4a and a second extension 632 extending rearward from the aforementioned first extension 631.

[0476] The second extension 632 extends offset from the edge of the mounting portion 4a, thereby forming a step in the rear peripheral portion 63.

[0477] The second extension 632 is positioned on the outer side of the mounting portion 4a, which is offset from the first extension 631, thereby forming a step on the rear periphery 63 of the louver portion 60.

[0478] The end of the edge of the mounting portion 4a contacts the first extension 631 of the rear peripheral portion 63, thereby restricting movement in the front-rear direction.

[0479] The outer edge of the mounting portion 4a contacts the second extension 632, thereby preventing the mounting portion 4a from moving in the left-right direction.

[0480] Therefore, by using the step of the rear periphery 63 to prevent the mounting part 4a from moving in the front-back and left-right directions, it is possible to effectively prevent air from leaking along the gap between the edge of the mounting part 4a and the louver part 60.

[0481] Figure 30 The above is shown Figure 27 A magnified view of region D.

[0482] As described above, the edge of the fan panel 5 can overlap with the air duct cover 6.

[0483] The edge of the aforementioned fan panel 5 overlaps with the aforementioned air duct cover 6, thereby preventing air passing through the aforementioned fan 30 from leaking between the front surface of the aforementioned fan panel 5 and the aforementioned air duct cover 6.

[0484] The connecting portion 65 of the aforementioned air duct cover 6 is provided to overlap with the edge of the aforementioned fan panel 5.

[0485] The connecting portion 65 is a recessed surface that connects the cover portion 64 and the louver portion 60, thus allowing easy contact with the fan panel 5.

[0486] The connecting portion 65 may be provided with a fan panel overlapping portion 653 that is recessed forward and contacts the edge of the fan panel 5.

[0487] The edge of the aforementioned fan panel 5 may overlap with the side ends of the aforementioned connecting portions 65 on both sides facing each other, and the overlapping portion 653 of the fan panel may be formed at the side ends of the aforementioned connecting portions 65 facing each other.

[0488] A portion of the side ends of the connecting portions 65 facing each other is recessed forward and supports the edge of the fan panel 5 in the front-back direction. The side end of the edge of the fan panel 5 in the width direction contacts the overlapping fixing portion 654 that extends in the front-back direction to connect the overlapping portion 653 of the fan panel and the connecting portion 65, thereby restricting the movement of the fan panel 5 in the left-right direction.

[0489] Figure 31 An embodiment is shown in which air is prevented from leaking to other parts outside the side end of the fan panel 5 when the air flowing through the protective panel 4 toward the front of the fan panel 5.

[0490] Figure 32 The above-mentioned setting is shown Figure 31 The aforementioned connecting buckle 52 in area G is engaged with the aforementioned protective panel 4.

[0491] The aforementioned connecting buckle 52 may have a connecting buckle sealing portion 521 that overlaps with the edge of the aforementioned mounting portion 4a.

[0492] The edge of the mounting portion 4a extends forward, and the connecting snap-lock sealing portion 521 may include a first flange 521a extending rearward toward the edge of the mounting portion 4a and a second flange 521b extending rearward from the first flange 521a in a manner offset from the edge of the mounting portion 4a.

[0493] The edge of the mounting portion 4a overlaps with the second flange 521b, and the extended end of the edge of the mounting portion 4a can contact the first flange 521a.

[0494] The second flange 521b is positioned on the upper or lower side than the first flange 521a.

[0495] The connecting portion of the connecting buckle 52 may be provided at the extended end of the second flange 521b.

[0496] The end of the mounting portion 4a extending forward can contact the extended end of the first flange 521a.

[0497] The surface of the end of the mounting portion 4a that extends forward and is perpendicular to the extension direction can contact the second flange 521b.

[0498] In one embodiment of the present invention, when the upper edge of the mounting portion 4a extends forward, the first flange 521a can contact the extended end of the upper edge of the mounting portion 4a, and the second flange 521b can contact the upper surface of the extended end of the upper edge of the mounting portion 4a. Therefore, the connecting buckle 52 can be fixed to the fixing end 4b disposed on the upper side of the mounting portion 4a.

[0499] The aforementioned connecting snap-lock sealing part 521 can prevent air leakage to the joint of at least one of the upper and lower sides of the aforementioned protective cover panel 4 and the aforementioned fan panel 5.

[0500] Figure 33 The above is shown Figure 31 The state of the motor mounting surface 53 of the aforementioned fan panel 5.

[0501] The aforementioned air supply motor 33 can be connected to a rotating shaft in order to transmit rotational force to the aforementioned air supply fan 30.

[0502] The aforementioned air supply motor 33 is provided on the motor mounting surface 53 located on the front surface of the aforementioned fan panel 5. The rotation shaft of the aforementioned air supply motor 33 can be connected to the aforementioned air supply fan 30 located behind the aforementioned fan panel 5 through the aforementioned shaft through hole 532 provided in a manner that penetrates the aforementioned motor mounting surface 53.

[0503] The motor mounting surface 53 may be provided with the motor sealing part 531, which prevents the air passing through the fan 30 from leaking between the fan motor 33 and the motor mounting surface 53.

[0504] The motor seal 531 described above can be formed as a closed curve shape including the shaft through hole 532 described above.

[0505] The motor seal 531 is made of an elastic material that extends along the periphery of the motor mounting surface 53 and is attached to the front surface.

[0506] The motor seal 531 may be located between the rear surface of the air supply motor 31 and the front surface of the motor mounting surface 53.

[0507] The motor mounting surface 53 may be provided with the motor rigid rib 533, which extends along the periphery of the shaft through hole 532 toward the edge of the motor mounting surface 53.

[0508] The motor rigid rib 533 is arranged radially with one end in contact with the shaft through hole 532 and the other end in contact with the motor seal 531, thereby enhancing the strength of the motor mounting surface 53.

[0509] The aforementioned motor rigid ribs 533 are provided in multiple and arranged radially, thereby enhancing the strength of the aforementioned motor mounting surface 53.

[0510] The aforementioned motor rigid rib 533 is formed in a shape that protrudes forward more than the aforementioned motor mounting surface 53, with one end contacting the aforementioned shaft through hole 532 and the other end extending to contact the aforementioned motor sealing part 531.

[0511] The motor seal portion 531 does not protrude further forward than the motor rigid rib 533, so that the sealing efficiency of the motor seal portion 531 will not decrease due to the motor rigid rib 533.

[0512] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and can be manufactured in various different forms. Those skilled in the art can implement different specific forms without changing the technical concept or essential features of the present invention.
