[0038] The housing 1 further includes a second side plate, which is arranged opposite to the first side plate 11 , and a direction from the second side plate to the first side plate 11 is parallel to the third direction Z.

[0039] The first direction X intersects with the second direction Y, the second direction Y intersects with the third direction Z, and the first direction X intersects with the third direction Z.

[0040] Optionally, the first direction X is perpendicular to the second direction Y, the second direction Y is perpendicular to the third direction Z, and the first direction X is perpendicular to the third direction Z.

[0041] Optionally, the housing 1 is made of sheet metal.

[0042] In some embodiments, the air conditioner indoor unit includes a volute 4 , which is disposed in the housing 1 .

[0043] refer to Figure 2 In some embodiments, a plurality of connection points 21 are provided at circumferential intervals along the knock-off plate 2, and the knock-off plate 2 is connected to the first side plate 11 through the plurality of connection points 21. The knock-off plate 2 can be removed by disconnecting the plurality of connection points 21, and a fresh air outlet is formed at the location of the knock-off plate 2, and the fresh air outlet is used to connect the fresh air duct.

[0044] The number of the plurality of connection points 21 may be 2, 3 or 4, etc. Optionally, the diameter of the connection point 21 is a plurality of sizes such as aperture R2\aperture R1.25, etc. The number of the connection points 21 and the diameter of the connection points are not limited to the scope provided in the embodiment of the utility model.

[0045] In some embodiments, a plurality of connection holes 22 are provided on the first side panel 11, and the plurality of connection holes 22 are spaced circumferentially along the outer periphery of the knock-off plate 2. After the knock-off plate 2 is knocked off to form a fresh air outlet, the fresh air duct and the first side panel 11 can be connected at the connection holes 22 through a connector to fix the fresh air duct.

[0046] Optionally, the connection hole 22 is a screw hole. Figure 2 , four screw holes are provided to fix the fresh air duct and the first side plate 11. Of course, the number of screw holes is not limited to four, and 2 screw holes, 3 screw holes, 5 screw holes, 6 screw holes, etc. can also be used.

[0047] When the user needs to connect a fresh air system to the indoor unit of the air conditioner, the user knocks down the knock-off plate 2, connects the fresh air duct to the fresh air outlet, and fixes the fresh air duct to the first side plate 11 by a plurality of screws.

[0048] In some embodiments, the knock-off plate 2 can be a circular plate. Of course, the knock-off plate 2 is not limited to a circular plate, and can also be a variety of structural forms such as a square plate, a hexagonal plate, an octagonal plate, etc. The advantage of a circular plate is that when the edge size of the same circumference is the same, the cross-sectional area of ​​the circle is the largest, so the circular size is used as the preferred design.

[0049] In some embodiments, the reinforcement member 3 includes a first reinforcement member 31 disposed around at least a portion of the outer circumference of the knock-off plate 2 .

[0050] In the above embodiment, the first reinforcement 31 is arranged around at least part of the periphery of the knock-out plate 2, which can strengthen the structural strength around the fresh air outlet and prevent the fresh air outlet from being deformed during the disassembly process. At the same time, when the user does not use the fresh air outlet, the knock-out plate 2 is a weak structure and is prone to deformation. The first reinforcement 31 can prevent the shell from being deformed.

[0051] In some embodiments, the first reinforcement member 31 includes a first reinforcement rib 311 and a second reinforcement rib 312, the extension direction of the first reinforcement rib 311 is parallel to the first direction X, the second reinforcement rib 312 is connected to the first reinforcement rib 311, the extension direction of the second reinforcement rib 312 is parallel to the second direction Y, and the first direction X intersects with the second direction Y.

[0052] In the above embodiment, the first reinforcing ribs 311 and the second reinforcing ribs 312 can improve the structural strength of the periphery of the knock-off plate 2 in the first direction X and the second direction Y, and have a simple structure and low cost.

[0053] In some embodiments, the first reinforcement member 31 further includes a third reinforcement rib 313 , which is connected to the second reinforcement rib 312 and spaced apart from the first reinforcement rib 311 .

[0054] In the above embodiment, the third reinforcing rib 313 and the first reinforcing rib 311 form a double-pressed structure, which can further improve the structural strength of the knock-off plate 2 in the second direction Y.

[0055] Since the space on one side of the Y direction where the fresh air inlet is located is relatively large, the first reinforcement 31 is a double-pressed joint, and the first reinforcement 31 is arranged circumferentially around the knock-off plate 2, which can not only improve the structural strength of the fresh air inlet, but also effectively utilize the space.

[0056] After the knock-off plate 2 is removed, a fresh air outlet is formed at the location of the knock-off plate 2. When the knock-off plate 2 is not removed, the reinforcement 3 is used to improve the circumferential structural strength of the knock-off plate 2. After the knock-off plate 2 is removed, the reinforcement 3 is used to improve the circumferential structural strength of the fresh air outlet. Therefore, in the utility model, the reinforcement 3 improves the circumferential structural strength of the knock-off plate 2 and improves the circumferential structural strength of the fresh air outlet, both of which improve the structural strength of the same part, and both are for preventing deformation of the shell.

[0057] In some embodiments, the first reinforcing rib 311 is closer to the knock-off plate 2 relative to the third reinforcing rib 313. If the first reinforcing rib 311 is too close to the knock-off plate 2, the new air outlet will be deformed due to the setting of the reinforcing member 3. If the first reinforcing rib 311 is too far from the knock-off plate 2, the effect of improving the structural strength of the new air outlet will be poor. Therefore, optionally, the shortest distance a between the first reinforcing rib 311 and the edge of the new air outlet is in the range of 17 mm to 22 mm. This distance range enables the first reinforcing member 1 to effectively improve the strength of the new air outlet along the second direction Y, improve the sheet metal structure strength after the knock-off plate 2 is knocked off, and will not cause deformation of the new air outlet due to the setting of the first reinforcing rib 311.

[0058] In some embodiments, the second reinforcing rib 312 extends in the direction of the knock-off plate 2, and the shortest distance c between the end of the second reinforcing rib 312 closest to the outer edge of the knock-off plate 2 and the outer edge of the knock-off plate 2 is in the range of 17 mm to 22 mm. This distance range enables the first reinforcing member 1 to effectively improve the strength of the fresh air outlet along the first direction X, improve the strength of the sheet metal structure after the knock-off plate 2 is knocked off, and the second reinforcing rib 312 will not cause deformation of the fresh air outlet.

[0059] In some embodiments, the reinforcement member 3 further includes a second reinforcement member 32. The second reinforcement member 32 is disposed around at least a portion of the outer circumference of the knock-off plate 2.

[0060] In some embodiments, the first reinforcement member 31 and the second reinforcement member 32 are disposed opposite to each other, and both the first reinforcement member 31 and the second reinforcement member 32 are disposed around at least a portion of the outer circumference of the knock-off plate 2 .

[0061] Since there is a large space on both sides of the fresh air outlet in the Y direction, the first reinforcement 31 and the second reinforcement 32 are arranged relatively relatively, respectively located on both sides of the knock-off plate 2 in the second direction Y, which can effectively improve the structural strength of the fresh air outlet and can effectively utilize the space.

[0062] In some embodiments, the second reinforcement member 32 includes a fourth reinforcement rib 321 and a fifth reinforcement rib 322, the extension direction of the fourth reinforcement rib 321 is parallel to the first direction X, the fifth reinforcement rib 322 is connected to the fourth reinforcement rib 321, the extension direction of the fifth reinforcement rib 322 is parallel to the second direction Y, and the first direction X intersects with the second direction Y.

[0063] In the above embodiment, the second reinforcement member 32 is a single-pressure structure, which can not only effectively utilize the space on the side of the fresh air outlet, but also prevent the fresh air outlet from being deformed due to the arrangement of the second reinforcement member 32 .

[0064] In some embodiments, the shortest distance b between the fourth reinforcing rib 321 and the edge of the fresh air outlet is 15 mm to 20 mm. This distance enables the second reinforcing member 32 to effectively improve the strength of the fresh air outlet along the second direction Y, improve the strength of the sheet metal structure after the knock-off plate 2 is knocked off, and will not cause the fourth reinforcing rib 321 to cause deformation of the fresh air outlet due to the short distance.

[0065] In some embodiments, the fifth reinforcing rib 322 extends in the direction of the knock-off plate 2, and the shortest distance d between the end of the fifth reinforcing rib 322 closest to the outer edge of the knock-off plate 2 and the outer edge of the knock-off plate 2 is in the range of 15 mm to 20 mm. This distance range enables the second reinforcing member 2 to effectively improve the strength of the fresh air outlet along the first direction X, improve the strength of the sheet metal structure after the knock-off plate 2 is knocked off, and the setting of the fifth reinforcing rib 322 will not cause deformation of the fresh air outlet due to the close distance.

[0066] In some embodiments, the reinforcement member 3 further includes a third reinforcement member 33 .

[0067] In some embodiments, the spacing direction between the third reinforcement 33 and the knock-off plate 2 is parallel to the first direction X, the spacing direction between the first reinforcement 31, the knock-off plate 2 and the second reinforcement 32 is parallel to the second direction Y, and the first direction X intersects with the second direction Y.

[0069] In some embodiments, the third reinforcement 33 is disposed on a first side of the knock-off plate 2 in the first direction X, and portions of the first reinforcement 31 and the second reinforcement 32 are disposed on a second side of the knock-off plate 2 in the first direction X.

[0070] In the above embodiment, the third reinforcement 33 can improve the strength of the fresh air outlet on the first side of the knock-off plate 2 located in the first direction X, and parts of the first reinforcement 31 and the second reinforcement 32 can improve the strength of the fresh air outlet on the second side of the knock-off plate 2 located in the first direction X, and the first reinforcement 31 and the second reinforcement 32 are arranged along the second direction Y, which can improve the strength of the fresh air outlet in the second direction X of the knock-off plate 2. Therefore, the reinforcement 3 can be basically arranged around the entire circumference of the knock-off plate 2 to improve the structural strength in the circumferential direction of the new air outlet.

[0071] In some embodiments, the third reinforcement member 33 is configured as a long strip-shaped plate, and an extending direction of the third reinforcement member 33 is parallel to the second direction Y.

[0072] In the above embodiment, the third reinforcement 33 can increase the strength of the fresh air outlet on the first side of the knock-off plate 2 in the first direction X. The extension direction of the third reinforcement 33 is parallel to the second direction Y, and can also increase the strength of the fresh air outlet in the second direction Y.

[0073] refer to Figure 3 In some embodiments, an air outlet side 101 and an air return side 102 are provided on the housing 1 , and the knock-off plate 2 is disposed close to the air return side 102 .

[0074] The knock-off plate 2 is located behind the return air outlet of the volute 4. Considering the strength of the first side plate 11, the knock-off plate 2 is set as far as possible behind the first side plate 11, that is, the position closest to the return air side 102 of the air conditioner indoor unit.

[0075] In some embodiments, the reinforcement member 3 further includes a third reinforcement member 33 , and the third reinforcement member 33 is closer to the air outlet side 101 relative to the knock-off plate 2 .

[0076] In the above embodiment, the third reinforcement member 33 is closer to the air outlet side 101 relative to the knock-off plate 2 , so that the space between the knock-off plate 2 and the air outlet side 101 can be reasonably utilized.

[0077] The third reinforcement 33 can improve the strength of the fresh air outlet on the first side of the knock-off plate 2 in the first direction X. The extension direction of the third reinforcement 33 is parallel to the second direction Y, and can also improve the strength of the fresh air outlet in the second direction Y.

[0078] In some embodiments, the reinforcement 3 further includes a first reinforcement 31 and a second reinforcement 32 , which are disposed on opposite sides of the knock-off plate 2 , and are at the same distance from the air outlet side 101 .
