[0047] Figure 1 is a schematic structural diagram of an air duct component according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 10 The embodiment of the utility model provides an air duct component for an indoor unit of an air conditioner. The air duct component includes an air duct frame 200 , a heat exchanger 100 and a supporting structure 300 .

[0048] An air duct is defined in the air duct frame 200. A first side support column 231 and a second side support column 232 are formed on both sides of the front end of the air duct frame 200 in parallel and spaced apart.

[0049] The heat exchanger 100 includes a body 101 and a refrigerant inlet and outlet pipe 120 extending from the front end of the body 101 and extending along the length direction of the first side support column 231. The refrigerant inlet and outlet pipes 120 are arranged at intervals in front of the first side support column 231. The body 101 is mounted on the rear side of the air duct frame 200 with the refrigerant inlet and outlet pipes 120 as a rotating cover.

[0050] The support structure 300 is fixedly connected to the first side support column 231 and protrudes forward. In the front-to-back direction, the front end of the support structure 300 is located in front of the refrigerant inlet and outlet pipe 120.

[0051] When the heat exchanger 100 needs to be installed on the air duct frame 200, the air duct frame 200 is placed flat on the support surface 400. Figure 4 As shown, at this time, the refrigerant inlet and outlet pipe 120 is between the bottom end of the first side support column 231 and the bottom end of the support structure 300, and the support structure 300 and the second side support column 232 are both in contact with the support surface 400 to avoid contact between the refrigerant inlet and outlet pipe 120 and the support surface 400.

[0052] During the installation of the heat exchanger 100, the duct frame 200 is horizontally placed on the support surface 400 through the support structure 300 and the second side support column 232, and the side of the heat exchanger 100 connected to the refrigerant inlet and outlet pipe 120 is placed close to the first side support column 231, and the heat exchanger 100 is covered on the duct frame 200 from the upper side.

[0053] In this embodiment, when the air duct frame 200 is placed flat on the support surface 400, the refrigerant inlet and outlet pipes 120 are located at the lower side of the first side support column 231 to avoid interference with the air duct formed on the upper side of the first side support column 231 and the second side support column 232. Due to the setting of the support structure 300, the side of the heat exchanger 100 close to the first side support column 231 is raised. During the installation of the heat exchanger 100, the refrigerant inlet and outlet pipes 120 are higher than the lowest point of the support structure 300, which prevents the refrigerant inlet and outlet pipes 120 from being squeezed by the support surface 400, resulting in deformation or breakage of the refrigerant inlet and outlet pipes 120.

[0054] In some embodiments of the present invention, Figure 1 As shown, the support structure 300 includes a first support structure 310. The air duct frame 200 is arranged vertically, and the first support structure 310 is located at the lower end of the first side support column. The first support structure 310 includes a first support leg 311 and a second support leg 312 arranged at intervals along the left and right sides, and the refrigerant inlet and outlet pipe 120 is located between the first support leg 311 and the second support leg 312.

[0055] In this embodiment, the refrigerant inlet and outlet pipe 120 is located between the first supporting leg 311 and the second supporting leg 312 to limit the refrigerant inlet and outlet pipe 120 and prevent the position of the heat exchanger 100 from deviating during the installation of the heat exchanger 100 .

[0056] In some embodiments of the present invention, the second support leg 312 is located on a side of the refrigerant inlet and outlet pipe 120 close to the second side support column 232 , and the front end of the second support leg 312 is located in front of the front end of the first support leg 311 .

[0057] Furthermore, if Figure 5 As shown, when the air duct frame 200 is placed flat on the support surface 400, the lower end of the second support leg 312 is located below the lower end of the first support leg 311, and the refrigerant inlet and outlet pipe 120 passes through the lower side of the first support leg 311 and is placed between the first support leg 311 and the second support leg 312.

[0058] In this embodiment, when installing the heat exchanger 100, Figure 5 As shown, the refrigerant inlet and outlet pipe 120 is first arranged between the first support leg 311 and the second support leg 312. The body 101 is rotated toward the air duct around the refrigerant inlet and outlet pipe 120 so that the body 101 is covered on the peripheral side of the air duct frame 200 away from the air duct.

[0059] In some embodiments of the present invention, Figure 4 As shown, the support structure 300 further includes a second support structure 320 , and the second support structure 320 is located at the upper end of the first side support column 231 .

[0060] Preferably, the second supporting structure 320 and the first supporting structure 310 are respectively located at two ends of the first edge supporting column 231 in the length direction.

[0061] In this embodiment, the placement of the air duct component is more stable through the contact between the second support structure 320 and the first support structure 310 at both ends of the length direction of the first side support column 231 and the second side support column 232 and the support surface 400, which reduces the possibility of the air duct component tilting or overturning.

[0062] Furthermore, when the air duct frame 200 is placed flat on the support surface 400, the bottom end of the second support structure 320 is not higher than the bottom end of the first support structure 310 to prevent the air duct component from tipping over due to the shift of the center of gravity after the refrigerant inlet and outlet pipes 120 are installed on the air duct frame 200.

[0063] In some embodiments of the present invention, the support structure 300 is integrally formed on the first side support column 231 .

[0064] In this embodiment, the support structure 300 and the first side support column 231 are integrally formed, thereby avoiding the subsequent installation steps and reducing the installation workload.

[0065] In some embodiments of the present invention, the support structure 300 is detachably connected to the first side support column 231, and the support structure 300 can be removed after the air duct component is installed to save the internal space of the air conditioner indoor unit.

[0066] In some embodiments of the present invention, Figure 8 As shown, the main body 101 is vertically arranged, and the main body 101 has two vertically arranged side mounting members 110 .

[0067] like Figure 1 As shown, the air duct frame 200 includes an upper tray 210 and a lower tray 220, and both ends of the first side support column 231 and the second side support column 232 are connected to the upper tray 210 and the lower tray 220 respectively.

[0068] The body 101 is located between the upper tray 210 and the lower tray 220 , and the two side mounting members 110 are respectively disposed adjacent to the first side supporting column 231 and the second side supporting column 232 .

[0069] like Figure 2 As shown, a first stop surface 211 that contacts a side surface of the body 101 is disposed on the lower side of the upper tray 210 .

[0070] Or, if Figure 3 As shown, a second stop surface 221 that contacts the side surface of the body 101 is disposed on the upper side of the lower tray 220 .

[0071] Preferably, a first stop surface 211 in contact with the side surface of the body 101 is disposed on the lower side of the upper tray 210 , and a second stop surface 221 in contact with the side surface of the body 101 is disposed on the upper side of the lower tray 220 .

[0072] In this embodiment, the first stop surface 211 and the second stop surface 221 are used to stop the main body 101 when the main body 101 moves to a preset position, and also provide certain support for the main body 101 after the main body 101 is installed, thereby reducing the shaking of the heat exchanger 100.

[0073] Furthermore, the body 101 is U-shaped, and the concave side of the body 101 is matched with the first stop surface 211 and the second stop surface 221 to improve the stability of the body 101 after installation and reduce the shaking of the heat exchanger 100.

[0074] Taking the example of the main body 101 being rotatably installed on the air duct frame 200, the main body 101 rotates around the refrigerant inlet and outlet pipe 120 toward the air duct until the bottom surface of the main body 101 contacts the first stop surface 211 and the second stop surface 221. At this time, the main body 101 is in the preset position for installing the main body 101.

[0075] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, each edge mounting member 110 includes an end plate 113, a first flange 111 and a second flange 112. The end plate 113 is vertically arranged, and the heat exchange tubes of the heat exchanger 100 pass through the end plate 113.

[0076] The first flange 111 is connected to a vertical edge of the end plate 113 on one side adjacent to the corresponding first side support column 231 or second side support column 232 .

[0077] The second flange 112 is connected to the vertical edge of the other side of the end plate 113 . The first flange 111 and the second flange 112 are located on both sides of the end plate 113 .

[0078] In some embodiments of the air duct component of the present invention, Figure 2 and Figure 7 As shown, two first stop blocks 212 are further disposed on the lower side of the upper tray 210 , and each first stop block 212 contacts the outer side of one edge mounting member 110 .

[0079] In this embodiment, the two first stop blocks 212 contact the edge mounting member 110 to stop the body 101 so that the body 101 is installed at a preset position. The provision of the first stop blocks 212 simplifies the positioning method of the heat exchanger 100 and improves the installation efficiency of the heat exchanger 100.

[0080] In some embodiments of the air duct component of the present invention, two second stop blocks 222 are further disposed on the upper side of the lower tray 220 , and each second stop block 222 contacts the outer side of one edge mounting member 110 .

[0081] In this embodiment, the two second stop blocks 222 contact the edge mounting member 110 to stop the body 101 so that the body 101 is installed at a preset position. The provision of the second stop blocks 222 simplifies the positioning method of the heat exchanger 100 and improves the installation efficiency of the heat exchanger 100.

[0082] Furthermore, the edge of the first flange 111 away from the end plate 113 contacts the first stop block 212 , and the edge of the first flange 111 away from the end plate 113 contacts the second stop block 222 .

[0083] In some embodiments of the air duct component of the present invention, each edge mounting member 110 is respectively connected to the first edge supporting column 231 and the second edge supporting column 232 via a third fixing structure.

[0084] Furthermore, each first flange 111 is connected to the first side support column 231 and the second side support column 232 respectively through a third fixing structure.

[0085] Preferably, the third fixing structure is a screw, and a through hole is provided on the third mounting plate. The screw is threadedly connected to the through hole to fix the edge mounting member 110 to the first edge support column 231 or the second edge support column 232 .

[0086] In some embodiments of the air duct component of the present invention, Figure 8 and Fig. 9 As shown, each edge mounting member 110 has a first mounting plate 114 extending outward at one end and a second mounting plate 115 extending outward at the other end. The first mounting plate 114 is fixedly connected to the upper tray 210 via a first fixing structure, and the second mounting plate 115 is fixedly connected to the lower tray 220 via a second fixing structure.

[0087] Preferably, the first fixing structure is a screw, and a through hole is provided on the first mounting plate 114 . The screw is threadedly connected to the through hole to fix the first mounting plate 114 to the upper tray 210 .

[0088] The second fixing structure is a screw. A through hole is provided on the second mounting plate 115 . The screw is threadedly connected to the through hole to fix the second mounting plate 115 to the lower tray 220 .

[0089] Alternatively, the first fixing structure or the second fixing structure may also be glue, and the edge mounting member 110 is fixed to the first structural member by gluing.

[0090] Alternatively, the first fixing structure or the second fixing structure may also be a magnetic member, and the edge mounting member 110 is fixed to the first structural member by magnetic attraction.

[0091] Furthermore, the first mounting plate 114 and the second mounting plate 115 are both connected to the end plate 113 .

[0092] The embodiment of the utility model further provides an air conditioner indoor unit. The air conditioner indoor unit comprises a casing and an air duct component in any of the above embodiments. The air duct component is installed in the casing.

[0093] In this embodiment, the housing is sleeved on the outside of the air duct component to support the air duct component. When the air duct frame 200 is placed horizontally on the support surface 400, the refrigerant inlet and outlet pipes 120 are located at the lower side of the first side support column 231 to avoid interference with the air duct formed on the upper side of the first side support column 231 and the second side support column 232. Due to the setting of the support structure 300, the side of the heat exchanger 100 close to the first side support column 231 is raised. During the installation of the heat exchanger 100, the refrigerant inlet and outlet pipes 120 are higher than the lowest point of the support structure 300, which avoids the refrigerant inlet and outlet pipes 120 being squeezed by the support surface 400, resulting in deformation or breakage of the refrigerant inlet and outlet pipes 120.
