Description

Technical Field

[0002] With the advancement of science and technology, people's living standards continue to improve, and the variety of air conditioners has also increased. For example, there are wall-mounted air conditioners, floor-standing / cabinet air conditioners, window air conditioners, ceiling air conditioners, etc. Floor-standing / cabinet air conditioners are particularly popular among users due to their easy installation, simple and elegant appearance, and powerful airflow, cooling and heating performance.

[0003] Currently, in existing technology, the rear side of the indoor unit of a floor-standing / table-type air conditioner is equipped with an air intake portion, such as an air intake grille / inlet, to facilitate air intake. However, because the air intake grille / inlet and other air intake portions occupy a large portion of the rear housing, the strength of the portion of the rear housing adjacent to the air intake grille / inlet is significantly reduced, particularly the portion between the two air intake grilles / inlet. This makes it very easy for the user to bump into the portion of the housing adjacent to the air intake grille / inlet during relocation or routine maintenance, thus compromising the user experience.

[0082] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the vertical air-conditioning indoor unit includes a housing 100 , a heat exchanger bracket 200 and a heat exchange reinforcement rib 300 .

[0083] The housing 100 includes a front shell 110 and a rear shell 120 that is snap-fitted to the rear of the front shell 110 . An air inlet 130 is disposed on the rear shell 120 .

[0084] The heat exchanger bracket 200 is disposed in the housing 100 and extends in the up-down direction. A placement space 210 for arranging the indoor heat exchanger is formed on the heat exchanger bracket 200 .

[0085] The heat exchange reinforcement rib 300 is connected to the rear of the heat exchanger bracket 200, and the heat exchange reinforcement rib 300 extends laterally and surrounds the placement space 210. The heat exchange reinforcement rib 300 is connected to the inner side of the rear shell 120, and the heat exchange reinforcement rib 300 is connected to the part of the rear shell 120 adjacent to the air inlet part 130.

[0086] Because the heat exchanger bracket 200 of the vertical air conditioner indoor unit of this embodiment is provided with heat exchange reinforcement ribs 300, the ribs 300 can enhance the strength of the heat exchanger bracket 200, thereby ensuring the installation stability of the indoor heat exchanger. Furthermore, because the heat exchange reinforcement ribs 300 are connected to the rear housing 120, specifically to the portion of the rear housing 120 adjacent to the air inlet 130, the heat exchange reinforcement ribs 300 can enhance the strength of the portion of the rear housing 120 adjacent to the air inlet 130 while ensuring the strength of the heat exchanger bracket 200.

[0087] Therefore, the vertical air-conditioning indoor unit of this embodiment can effectively prevent the portion of the housing 100 adjacent to the air inlet portion 130 from being damaged after being bumped, thereby improving the user experience.

[0088] In addition, in the prior art, a filter rail is provided at the bottom and / or top of the air inlet portion 130 and the air inlet filter element 400 , and a filter chute 500 is provided on the filter rail. Furthermore, the filter rail can be used to position the air inlet filter 400 to ensure the installation stability of the air inlet filter 400 after it is installed in place; and, a disassembly opening 140 is also provided on the housing 100 of the vertical air-conditioning indoor unit, and the disassembly opening 140 is adjacent to the left end / right end of the air inlet part 130, and the filter chute 500 is connected to the disassembly opening 140, so that the air inlet filter 400 can slide into the filter chute 500 through the disassembly opening 140, and be installed to a position opposite to the air inlet part 130 along the filter chute 500, and then the filter rail can be used to limit the sliding trajectory of the air inlet filter 400 from the disassembly opening 140 to the position opposite to the air inlet part 130, so that the air inlet filter 400 can be installed very smoothly and stably in the process of being installed from the disassembly opening 140 to the position opposite to the air inlet part 130.

[0089] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the vertical air-conditioning indoor unit includes an air inlet filter 400 .

[0090] The air inlet filter 400 is disposed on the inner side of the rear housing 120 . The air inlet filter 400 is disposed opposite to the air inlet portion 130 . The air inlet filter 400 is used to purify the airflow flowing into the housing 100 from the air inlet portion 130 .

[0091] A filter chute 500 extending transversely along the air inlet portion 130 is formed between the heat exchange reinforcement rib 300 and the rear housing 120 . The air inlet filter 400 is disposed in the filter chute 500 . The filter chute 500 is used to limit the air inlet filter 400 .

[0092] Because the vertical air conditioner indoor unit of this embodiment is connected to the rear housing 120 via the heat exchange reinforcement ribs 300, a filter chute 500 extending transversely along the air inlet 130 can be formed directly between the heat exchange reinforcement ribs 300 and the rear housing 120. Compared to the prior art, which provides filter rails independently of the heat exchange reinforcement ribs 300, the vertical air conditioner indoor unit of this embodiment, while provided with the heat exchange reinforcement ribs 300, can directly connect the heat exchange reinforcement ribs 300 to the rear housing 120 to form the filter chute 500, eliminating the need for a separate filter rail. Therefore, this embodiment effectively reduces the amount of plastic components used in the housing 100 of the vertical air conditioner indoor unit while simultaneously positioning and defining the sliding path of the air inlet filter 400, thereby ensuring the environmental friendliness of the vertical air conditioner indoor unit and reducing the production cost of the vertical air conditioner indoor unit.

[0093] Reference Figure 2In the first embodiment of the connection between the heat exchange reinforcement rib 300 and the heat exchanger support 200, the heat exchange reinforcement rib 300 and the heat exchanger support 200 can be an integrated structure. This ensures the strength and stability of the connection between the heat exchange reinforcement rib 300 and the heat exchanger support 200, and further ensures the strength of the portion of the rear housing 120 adjacent to the air inlet 130.

[0094] In addition, in the prior art, most vertical air conditioner indoor units are columnar, and thus the air inlet filter 400 and the filter rail are both arc-shaped. Furthermore, since the air inlet filter 400 needs to be cleaned and replaced regularly during use, when the air inlet filter 400 is pulled out of the filter rail through the removal opening 140 of the vertical air conditioner indoor unit, or when the air inlet filter 400 is installed, the air inlet filter 400 frequently rubs against the portion of the filter rail located inside the filter chute 500 (away from the rear housing 120). This can cause wear on the air inlet filter 400 and the inner side of the filter rail (away from the rear housing 120), rendering the filter rail's positioning function for the air inlet filter 400 and its sliding trajectory ineffective, and can even damage the inner side of the filter rail (away from the rear housing 120). However, since the filter rail and the rear shell 120 are an integrated structure, in order to repair and replace the inner side of the filter rail (away from the rear shell 120), the entire rear shell 120 needs to be replaced. This increases the replacement and maintenance cost of the filter rail of the vertical air-conditioning indoor unit and reduces the user experience.

[0095] Reference Figure 2 In the second embodiment of the connection method between the heat exchange reinforcement rib 300 and the heat exchanger support 200 of this embodiment, the heat exchange reinforcement rib 300 and the rear housing 120 are detachably connected, and the connection between the heat exchange reinforcement rib 300 and the heat exchanger support 200 can be a detachable connection. For example, the two ends of the heat exchange reinforcement rib 300 are connected to the heat exchanger support 200 (the first connecting member 240 and the second connecting member 250) by screws; for another example, hooks (or blocks) are provided at both ends of the heat exchange reinforcement rib 300, and a hole (or slot) is provided on the heat exchanger support 200 (the first connecting member 240 and the second connecting member 250). Through the cooperation of the hooks and the hole (or, the block and the slot), the heat exchange reinforcement rib 300 is detachably connected to the heat exchanger support 200.

[0096] Because the heat exchange reinforcement rib 300 of the vertical air conditioner indoor unit of this embodiment is detachably connected to the rear housing 120, and the connection between the heat exchange reinforcement rib 300 and the heat exchanger bracket 200 is also detachable, when the user needs to repair or replace the side wall of the filter chute 500 away from the rear housing 120 that is severely worn or even damaged, the heat exchange reinforcement rib 300 can be directly replaced without replacing the entire rear housing 120. Therefore, the vertical air conditioner indoor unit of this embodiment reduces the cost of replacing and repairing the filter chute, ensuring a superior user experience.

[0097] Reference Figure 2 In this embodiment, the heat exchanger support 200 includes an upper top plate 220 , a lower bottom plate 230 , a first connecting member 240 and a second connecting member 250 .

[0098] The upper plate 220 is located at the top of the placement space 210 and is used to connect to the top end of the indoor heat exchanger.

[0099] The lower chassis 230 is located at the bottom of the placement space 210 and is used to connect the bottom end of the indoor heat exchanger.

[0100] The first connecting member 240 and the second connecting member 250 are connected between the upper top plate 220 and the lower bottom plate 230 along the up-down direction. The first connecting member 240 and the second connecting member 250 are respectively located on the left and right sides of the placement space 210 .

[0101] It is understandable that, through the above-mentioned specific configuration of the heat exchange bracket, most of the indoor heat exchanger is not covered by the heat exchanger bracket 200. This ensures the heat exchange efficiency of the indoor heat exchanger, the heating and cooling performance of the vertical air conditioner indoor unit, and the user experience.

[0102] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In the first implementation manner of the air inlet portion 130 of this embodiment, the air inlet portion 130 includes a first air inlet grille 131, and the air inlet filter 400 includes a first filter element 410 arranged opposite to the first air inlet grille 131; and the filter chute 500 includes a first filter element bottom chute 510.

[0103] The first filter element bottom chute 510 is located at the bottom of the first air inlet grille 131. The first filter element bottom chute 510 extends horizontally along the first air inlet grille 131, and the first filter element bottom chute 510 is set to open upward. The bottom of the first filter element 410 can be slidably set in the first filter element bottom chute 510. The first filter element bottom chute 510 is used to limit the bottom of the first filter element 410.

[0104] It is understandable that the heat exchange reinforcement rib 300 can be connected to the bottom of the first air inlet grille 131 to form a first filter element bottom slide groove 510 between the heat exchange reinforcement rib 300 and the rear shell 120, so as to increase the strength of the rear shell 120 located at the bottom of the first air inlet grille 131 while ensuring the strength of the heat exchanger bracket 200, and to limit the first filter element 410, thereby ensuring the installation stability of the first filter element 410 after it is installed in place and the smoothness and stability of the first filter element 410 during the installation process.

[0105] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this embodiment, a laterally extending first grille bottom reinforcement rib 121 is provided on the inner side of the rear shell 120 at a position corresponding to the heat exchange reinforcement rib 300, and the first grille bottom reinforcement rib 121 extends from the rear shell 120 to the heat exchange reinforcement rib 300, and the first grille bottom reinforcement rib 121 is located at the bottom of the first air inlet grille 131.

[0106] The rear housing 120 includes a first grille bottom end shielding portion 122 located at the bottom of the first air inlet grille 131 .

[0107] The heat exchange reinforcement rib 300 includes an upper limit portion 310 . The upper limit portion 310 extends transversely around the placement space 210 and extends transversely along the first air inlet grille 131 .

[0108] The first filter element bottom chute 510 is located between the upper limit portion 310 and the first grille bottom shielding portion 122 , and the first grille bottom reinforcing rib 121 is located at the bottom of the first filter element bottom chute 510 .

[0109] It can be understood that the first filter element bottom chute 510 is constructed by configuring the upper limit portion 310, the first grille bottom shielding portion 122 and the first grille bottom reinforcing rib 121.

[0110] In addition, the upper limit portion 310 can be a plate-like structure extending in the vertical direction, or a block-like structure with a certain length in the vertical direction, so that the first filter element bottom chute 510 has a certain depth to accommodate the first filter element 410.

[0111] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6In this embodiment, a mounting groove 123 is provided on the inner side of the rear outer shell 120 at a position corresponding to the heat exchange reinforcement rib 300. The mounting groove 123 extends laterally along (the rear outer shell 120) and opens toward the heat exchange reinforcement rib 300. The mounting groove 123 is located below the bottom reinforcement rib 121 of the first grille.

[0112] The heat exchange reinforcement rib 300 also includes a connecting portion 320. The connecting portion 320 extends laterally along the first air inlet grille 131 and is disposed in the placement space 210 along the transverse direction. Both ends of the connecting portion 320 are connected to the heat exchanger bracket 200. The connecting portion 320 protrudes toward the mounting slot 123 and is embedded in the mounting slot 123. The upper limit portion 310 is connected above the connecting portion 320.

[0113] It can be understood that the heat exchange reinforcement rib 300 can be connected to the rear shell 120 through the connecting portion 320 and the mounting groove 123, so as to increase the strength of the adjacent air inlet portion 130 of the rear shell 120 while ensuring the strength of the heat exchanger bracket 200, and realize the detachable connection between the heat exchange reinforcement rib 300 and the rear shell 120.

[0114] In addition, the connecting portion 320 may be a plate with a U-shaped cross section.

[0115] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In this embodiment, both ends of the connecting portion 320 are connected to the first connecting member 240 and the second connecting member 250 , respectively, and both ends of the upper limit portion 310 are connected to the first connecting member 240 and the second connecting member 250 , respectively.

[0116] It is understandable that, based on the specific structure of the heat exchanger support 200, the structural strength at the first connecting piece 240 and the second connecting piece 250 is the lowest. Therefore, the specific connection between the heat exchange reinforcement rib 300 and the heat exchanger support 200 can be that the two ends of the connecting portion 320 are respectively connected to the first connecting piece 240 and the second connecting piece 250, and the two ends of the upper limit portion 310 are respectively connected to the first connecting piece 240 and the second connecting piece 250. In this way, the heat exchange reinforcement rib 300 effectively ensures the strength of the heat exchanger support 200.

[0117] Reference Figure 8 and Figure 9In this embodiment, the first air inlet grille 131 is arranged near the top of the rear shell 120; and a first filter element top slide 530 is formed between the upper top plate 220 and the rear shell 120, which is located at the top of the first air inlet grille 131, and the first filter element top slide 530 extends laterally along the first air inlet grille 131, and the first filter element 410 is arranged in the first filter element top slide 530, and the first filter element top slide 530 is used to limit the top of the first filter element 410.

[0118] It is understood that the first air inlet grille 131 can be the air inlet portion 130 located at the top of the rear housing 120. Furthermore, the indoor heat exchanger is aligned with the air inlet portion 130 to ensure maximum heat exchange efficiency for the air conditioner indoor unit. Furthermore, the portion of the rear housing 120 above the first air inlet grille 131 can be positioned opposite the upper plate 220 of the heat exchanger bracket 200. Furthermore, the top of the first air inlet grille 131 can be positioned or its sliding path defined by forming a first filter element top slide 530 between the upper plate 220 and the rear housing 120. This eliminates the need for a separate filter slide rail on the top of the first air inlet grille 131. Furthermore, this embodiment not only secures the indoor heat exchanger, positions the air inlet filter 400, and defines its sliding path, but also further reduces the amount of plastic components used in the housing 100 of the vertical air conditioner indoor unit, ensuring its environmental friendliness and lowering its production cost.

[0119] In addition, when the first air inlet grille 131 is not the top air inlet portion 130 of the rear shell 120, the positioning of the top of the first filter element 410 and the definition of the sliding trajectory can be the same as the top positioning and sliding trajectory of the second filter element in the second embodiment of the air inlet portion 130 described below (that is, the first air inlet grille 131 can be regarded as the second air inlet grille 132 in the following embodiment, and the first filter element 410 is regarded as the second filter element in the following embodiment).

[0120] Reference Figure 8 、 Figure 9 and Figure 11 In this embodiment, a laterally extending first grille top reinforcement rib 126 is provided on the inner side of the rear shell 120 corresponding to the position of the upper top plate 220. The first grille top reinforcement rib 126 extends from the rear shell 120 to the upper top plate 220. The first grille top reinforcement rib 126 is located at the top of the first air inlet grille 131.

[0121] The rear housing 120 includes a first grille top end shielding portion 127 located at the top of the first air inlet grille 131 .

[0122] The upper top plate 220 includes a top plate limiting portion 221 extending laterally along the first air inlet grille 131, the first filter element top slide 530 is located between the top plate limiting portion 221 and the first grille top shielding portion 127, and the first grille top reinforcement rib 126 is located at the top of the first filter element top slide 530.

[0123] It is understandable that the construction of the first filter element top sliding groove 530 can be achieved by disposing the top plate limiting portion 221, the first grille top shielding portion 127 and the first grille top reinforcing rib 126.

[0124] Reference Figure 2 、 Figure 8 and Figure 10 In the second embodiment of the air inlet portion 130 of this embodiment, the air inlet portion 130 includes a second air inlet grille 132 , and the air inlet filter 400 includes a second filter element disposed opposite to the second air inlet grille 132 . The filter chute 500 includes a second filter element top chute 520 .

The second filter element top slide 520 extends laterally along the second air inlet grille 132, and the second filter element top slide 520 is set to open downward. The top of the second filter element can be slidably set in the second filter element top slide 520. The second filter element top slide 520 is used to limit the top of the second filter element.

[0126] It is understandable that the heat exchange reinforcement rib 300 can be connected to the top of the second air inlet grille 132 to form a second filter element top slide 520 between the heat exchange reinforcement rib 300 and the rear shell 120, so as to increase the strength of the rear shell 120 located on the top of the second air inlet grille 132 while ensuring the strength of the heat exchanger bracket 200, and to limit the second filter element, thereby ensuring the installation stability of the second filter element after it is installed in place and the smoothness and stability of the second filter element during the installation process.

[0127] Reference Figure 2 、 Figure 8 and Figure 10 In this embodiment, a laterally extending second grille top reinforcement rib 124 is provided on the inner side of the rear outer shell 120 at a position corresponding to the heat exchange reinforcement rib 300, and the second grille top reinforcement rib 124 extends from the rear outer shell 120 to the heat exchange reinforcement rib 300, and the second grille top reinforcement rib 124 is located at the bottom of the second air inlet grille 132.

[0128] The rear housing 120 includes a second grille top end shielding portion 125 located at the top of the second air inlet grille 132 .

[0129] The heat exchange reinforcement rib 300 includes a lower limiting portion.

[0130] The lower limiting portion extends in a transverse direction and surrounds the placement space 210 , and the lower limiting portion extends in a transverse direction along the second air inlet grille 132 .

[0131] The second filter element top chute 520 is located between the lower limit portion and the second grille top shielding portion 125 , and the second grille top reinforcing rib 124 is located on the top of the second filter element top chute 520 .

[0132] It can be understood that the second filter element top chute 520 is constructed by configuring the lower limit portion, the second grille top shielding portion 125 and the second grille top reinforcing rib 124 .

[0133] In addition, the lower limit portion can be a plate-like structure extending in the vertical direction, or a block-like structure with a certain length in the vertical direction, so that the second filter element top slide groove 520 has a certain depth to accommodate the second filter element.

[0134] Reference Figure 2 、 Figure 8 and Figure 10 In this embodiment, a mounting groove 123 is provided on the inner side of the rear housing 120 at a position corresponding to the heat exchange reinforcement rib 300. The mounting groove 123 extends laterally and opens toward the heat exchange reinforcement rib 300. The mounting groove 123 is located below the second grille top reinforcement rib 124. The heat exchange reinforcement rib 300 also includes a connecting portion 320.

[0135] The connecting portion 320 extends laterally along the second air inlet grille 132, and the connecting portion 320 is extended laterally and surrounded by the placement space 210. Both ends of the connecting portion 320 are connected to the heat exchanger bracket 200. The connecting portion 320 is protruded toward the mounting groove 123, and the connecting portion 320 is embedded in the mounting groove 123. The lower limit portion is connected to the bottom of the connecting portion 320.

[0136] It can be understood that the heat exchange reinforcement rib 300 can be connected to the rear shell 120 through the connecting portion 320 and the mounting groove 123, so as to increase the strength of the adjacent air inlet portion 130 of the rear shell 120 while ensuring the strength of the heat exchanger bracket 200, and realize the detachable connection between the heat exchange reinforcement rib 300 and the rear shell 120.

[0137] In addition, the connecting portion 320 may be a plate with a U-shaped cross section.

[0138] Reference Figure 2 、 Figure 8 and Figure 10 In this embodiment, both ends of the connecting portion 320 are connected to the first connecting member 240 and the second connecting member 250 , respectively, and both ends of the lower limiting portion are connected to the first connecting member 240 and the second connecting member 250 , respectively.

[0139] It is understandable that, based on the specific structure of the heat exchanger support 200, the structural strength at the first connecting piece 240 and the second connecting piece 250 is the lowest. Therefore, the specific connection between the heat exchange reinforcement rib 300 and the heat exchanger support 200 can be that the two ends of the connecting portion 320 are respectively connected to the first connecting piece 240 and the second connecting piece 250, and the two ends of the lower limit portion are respectively connected to the first connecting piece 240 and the second connecting piece 250. In this way, the heat exchange reinforcement rib 300 effectively ensures the strength of the heat exchanger support 200.

[0140] Reference Figure 2 、 Figure 4 and Figure 7 In this embodiment, the second air inlet grille 132 is arranged near the bottom end of the rear shell 120; and a second filter element bottom chute 540 is formed between the lower chassis 230 and the rear shell 120, which is located at the bottom of the second air inlet grille 132, and the second filter element bottom chute 540 extends laterally along the second air inlet grille 132, and the second filter element is arranged in the second filter element bottom chute 540, and the second filter element bottom chute 540 is used to limit the bottom of the second filter element.

[0141] It is understood that the second air inlet grille 132 can be the air inlet portion 130 located at the bottom of the rear housing 120. Furthermore, the indoor heat exchanger is aligned with the air inlet portion 130 to ensure maximum heat exchange efficiency for the air conditioner indoor unit. Furthermore, the portion of the rear housing 120 below the second air inlet grille 132 can be positioned opposite the lower chassis 230 of the heat exchanger bracket 200. Furthermore, the positioning of the bottom of the second air inlet grille 132 or the definition of its sliding path can be achieved by forming a second filter bottom chute 540 between the lower chassis 230 and the rear housing 120. This eliminates the need for a separate filter rail at the bottom of the second air inlet grille 132. Furthermore, this embodiment not only secures the indoor heat exchanger, positions the air inlet filter 400, and defines its sliding path, but also further reduces the amount of plastic components used in the housing 100 of the vertical air conditioner indoor unit, ensuring the environmental friendliness of the vertical air conditioner indoor unit and lowering its production cost.

[0142] In addition, when the second air inlet grille 132 is not the air inlet portion 130 at the bottom of the rear shell 120, the positioning of the bottom of the second filter element and the definition of the sliding trajectory can be the same as the bottom positioning and the definition of the sliding trajectory of the first filter element 410 in the first embodiment of the above-mentioned air inlet portion 130 (that is, the second air inlet grille 132 can be regarded as the first air inlet grille 131 in the above-mentioned embodiment, and the second filter element is regarded as the first filter element 410 in the above-mentioned embodiment).

[0143] Reference Figure 2 、 Figure 4 、 Figure 7 and Figure 12 In this embodiment, a laterally extending second grille bottom reinforcement rib 128 is provided on the inner side of the rear shell 120 at a position corresponding to the lower chassis 230. The second grille bottom reinforcement rib 128 extends from the rear shell 120 to the lower chassis 230. The second grille bottom reinforcement rib 128 is located at the bottom of the second air inlet grille 132.

[0146] It is understandable that the second filter element top slide groove 520 can be constructed by disposing the chassis limiting portion 231, the second grille bottom end shielding portion 129 and the second grille bottom reinforcing rib 128.

The air inlet filter 400 includes both a first filter 410 disposed opposite the first air inlet grille 131 and a second filter disposed opposite the second air inlet grille 132.

[0150] It is understood that when the air inlet portion 130 includes multiple air inlet grilles arranged vertically, the heat exchange reinforcement ribs 300 can be connected between any two adjacent air inlet grilles. Furthermore, in two filter elements positioned opposite any two adjacent air inlet grilles, the heat exchange reinforcement ribs 300 can simultaneously position the filter element located above and the filter element located below, define their sliding paths, and ensure the strength of the rear housing 120 between any two adjacent air inlet grilles.

[0151] In addition, the mounting groove 123 is located between the bottom reinforcement rib of the first air inlet grille 131 and the top reinforcement rib of the second air inlet grille 132, and the mounting groove 123 can be directly formed by the bottom reinforcement rib of the first air inlet grille 131 and the top reinforcement rib of the second air inlet grille 132, that is, the upper and lower side walls of the mounting groove 123 can be part of the bottom reinforcement rib of the first air inlet grille 131 and the top reinforcement rib of the second air inlet grille 132.

[0152] Reference Figure 5 and Figure 10 In this embodiment, a weight-reducing groove 321 is provided on the side of the connecting portion 320 facing away from the mounting groove 123, so that the heat exchange reinforcement rib 300 can have greater strength while having less weight, thereby ensuring the environmental friendliness of the vertical air-conditioning indoor unit and reducing the production cost of the vertical air-conditioning indoor unit.
