Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a vertical air conditioner indoor unit with a replaceable slide rail limiting part. Background Art

[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 the prior art, the rear side of a floor-standing / cabinet-type air conditioner indoor unit is equipped with an air inlet, typically an air inlet grille / inlet port, to facilitate air intake. Furthermore, an air filter, such as a filter screen, is also located inside the air inlet to purify the airflow flowing from the air inlet into the housing. Specifically, a filter rail is provided at the air inlet grille, and a chute is provided within the filter rail. The air inlet filter is positioned within the chute to position the air inlet filter and define its sliding path. Furthermore, most floor-standing air conditioner indoor units are cylindrical, resulting in both the air inlet filter and the filter rail being arc-shaped. Because the air inlet filter requires regular cleaning and replacement during use, the air inlet filter frequently rubs against the portion of the filter rail located inside the filter chute (away from the rear housing) during removal from the filter rail through the removal opening of the floor-standing air conditioner indoor unit, or during installation. This can cause wear on the air inlet filter and the inner side of the filter rail (away from the rear housing), rendering the filter rail ineffective in positioning the air inlet filter and limiting its sliding trajectory, and can even damage the inner side of the filter rail (away from the rear housing). However, since the filter rail and the rear housing are an integrated structure, repairing or replacing the inner side of the filter rail (away from the rear housing) requires replacing the entire rear housing. This increases the cost of replacing the filter rail for the vertical air conditioner indoor unit and reduces the user experience. Utility Model Content

[0062] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the vertical air-conditioning indoor unit includes a housing 100 , an air inlet filter 400 and a slide rail limiting portion 300 .

[0063] 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 .

[0064] 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 .

[0065] The slide rail limiting portion 300 is detachably connected to the rear shell 120, and a filter chute 500 extending laterally along the air inlet portion 130 is formed between the slide rail limiting portion 300 and the rear shell 120. The air inlet filter 400 is arranged in the filter chute 500, and the filter chute 500 is used to limit the air inlet filter 400.

[0066] In the vertical air conditioner indoor unit of the present invention, the slide rail stopper 300, which forms a filter chute 500 extending transversely along the air inlet portion 130 between the slide rail stopper 300 and the rear housing 120, is detachably connected to the rear housing 120. Furthermore, when the user needs to repair or replace a severely worn or damaged slide rail stopper 300, they can simply remove and replace the slide rail stopper 300 without having to replace the entire rear housing 120.

[0067] Therefore, the vertical air-conditioning indoor unit of the present invention reduces the replacement and maintenance costs of the filter rails, and ensures the user experience.

[0068] It should also be noted that in the prior art, because the air inlet portion 130, such as the air inlet grille / inlet, occupies a large portion of the rear side of the housing 100 (the rear housing 120), the strength of the portion of the rear housing 120 adjacent to the air inlet grille / inlet of the floor-standing / table-type air conditioner indoor unit is significantly reduced, particularly the portion between the two air inlet grilles / inlets of the housing 100. As a result, if a user bumps into the portion of the housing 100 adjacent to the air inlet grille / inlet during relocation or routine maintenance, this portion is easily damaged, reducing the user experience.

[0069] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the slide rail limiting portion 300 is connected to the inner side of the rear housing 120 , and the slide rail limiting portion 300 is connected to a portion of the rear housing 120 adjacent to the air inlet portion 130 .

[0070] Since the slide rail limiter 300 is connected to the rear housing 120 , specifically, the slide rail limiter 300 can be detachably connected to the portion of the rear housing 120 adjacent to the air inlet 130 , and thus, the slide rail limiter 300 can increase the strength of the portion of the rear housing 120 adjacent to the air inlet 130 .

[0071] Therefore, the vertical air-conditioning indoor unit of this embodiment can also 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.

[0072] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In the first implementation of the air inlet portion 130 of the present 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. The filter chute 500 includes a first filter element bottom chute 510. The first filter element bottom chute 510 is located at the bottom of the first air inlet grille 131, and the first filter element bottom chute 510 extends laterally along the first air inlet grille 131, and the first filter element bottom chute 510 is arranged to open upward, and the bottom of the first filter element 410 is slidably arranged in the first filter element bottom chute 510, and the first filter element bottom chute 510 is used to limit the bottom of the first filter element 410.

[0073] It is understandable that the slide rail limiting portion 300 can be detachably provided at the bottom of the first air inlet grille 131 to form a first filter element bottom slide groove 510 between the slide rail limiting portion 300 and the rear shell 120, thereby limiting the bottom of the first filter element 410, ensuring the installation stability of the first filter element 410 after it is installed in place through the disassembly port 140, and ensuring the smoothness and stability of the first filter element 410 during the installation process; at the same time, the strength of the part of the rear shell 120 located at the bottom of the first air inlet grille 131 is ensured, thereby improving the user experience.

[0074] 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 slide rail limit portion 300, and the first grille bottom reinforcement rib 121 extends from the rear shell 120 to the slide rail limit portion 300, and the first grille bottom reinforcement rib 121 is located at the bottom of the first air inlet grille 131.

[0075] The rear housing 120 includes a first grille bottom end shielding portion 122 located at the bottom of the first air inlet grille 131. The slide rail limiting portion 300 includes an upper limit portion 310.

[0076] The upper limit portion 310 extends laterally along the first air inlet grille 131 .

[0077] 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 .

[0078] 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.

[0079] 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.

[0080] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In this embodiment, a mounting groove 123 is provided on the inner side of the rear housing 120 at a position corresponding to the slide rail stopper 300. The mounting groove 123 extends laterally and opens toward the slide rail stopper 300. The mounting groove 123 is located below the first grille bottom reinforcement rib 121. The slide rail stopper 300 also includes a connecting portion 320.

[0081] The connecting portion 320 extends laterally along the first air inlet grille 131 . 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 to the top of the connecting portion 320 .

[0082] It can be understood that the slide rail limit portion 300 can be detachably connected to the rear shell 120 through the connecting portion 320 and the mounting groove 123, specifically detachably connected to the bottom of the first air inlet grille 131, so as to reduce the replacement and maintenance costs of the filter slide rail while increasing the strength of the portion of the rear shell 120 adjacent to the air inlet portion 130.

[0083] In addition, the connecting portion 320 may be a plate with a U-shaped cross section.

[0084] Reference Figure 2 In this embodiment, the vertical air conditioner indoor unit includes a heat exchanger bracket 200 .

[0085] 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 .

[0086] The slide rail limiting portion 300 extends in a transverse direction and surrounds the placement space 210 , and both ends of the slide rail limiting portion 300 are detachably connected to the heat exchanger bracket 200 .

[0087] It can be understood that by detachably connecting the two ends of the slide rail limit portion 300 to the heat exchanger bracket 200, the above-mentioned reduction in the replacement and maintenance cost of the filter slide rail and the increase in the strength of the portion of the adjacent air inlet portion 130 of the rear shell 120 can be achieved, while also ensuring the strength of the heat exchanger bracket 200 and the stability of the indoor heat exchanger installation configuration.

[0088] 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 .

[0089] 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.

[0090] 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.

[0091] 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 in the up and down directions. 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, and the two ends of the slide rail limiting portion 300 are respectively detachably connected to the first connecting member 240 and the second connecting member 250.

[0092] 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.

[0093] Furthermore, the specific structure of the heat exchanger support 200 shows that the structural strength at the first connecting member 240 and the second connecting member 250 is the lowest. Therefore, the specific connection between the slide rail stopper 300 and the heat exchanger support 200 can be such that the two ends of the connecting portion 320 are respectively connected to the first connecting member 240 and the second connecting member 250, and the two ends of the upper limit portion 310 are respectively connected to the first connecting member 240 and the second connecting member 250. This allows the slide rail stopper 300 to effectively ensure the strength of the heat exchanger support 200.

[0094] In addition, the form in which the slide rail limiting part 300 is detachably connected to the heat exchanger bracket 200 can be: the two ends of the slide rail limiting part 300 are connected to the heat exchanger bracket 200 (the first connecting part 240 and the second connecting part 250) by screws; hooks (or blocks) can also be provided at both ends of the slide rail limiting part 300, and a card hole (or card slot) can be provided on the heat exchanger bracket 200 (the first connecting part 240 and the second connecting part 250), and the slide rail limiting part 300 can be detachably connected to the heat exchanger bracket 200 (the first connecting part 240 and the second connecting part 250) through the cooperation of the hook and the card hole (or, the card block and the card slot).

[0095] Reference Figure 7 and Figure 8 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 .

[0096] The second filter element top slide 520 is located at the top of the second air inlet grille 132. 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.

[0097] It is understandable that the slide rail limit portion 300 can be detachably arranged on the top of the second air inlet grille 132 to form a second filter element top slide groove 520 between the slide rail limit portion 300 and the rear shell 120, thereby limiting the bottom of the second filter element, 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; at the same time, the strength of the part of the rear shell 120 located at the bottom of the second air inlet grille 132 is ensured, thereby improving the user experience.

[0098] Reference Figure 7 and Figure 8 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 slide rail limit portion 300, and the second grille top reinforcement rib 124 extends from the rear outer shell 120 to the slide rail limit portion 300, and the second grille top reinforcement rib 124 is located at the bottom of the second air inlet grille 132.

[0099] The rear housing 120 includes a second grille top shielding portion 125 located at the top of the second air inlet grille 132. The slide rail limiting portion 300 includes a lower limiting portion.

[0100] The lower limiting portion extends laterally along the second air inlet grille 132 .

[0101] 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 .

[0102] 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 .

[0103] 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.

[0104] Reference Figure 7 and Figure 8 In this embodiment, a mounting groove 123 is provided on the inner side of the rear housing 120 at a position corresponding to the slide rail stopper 300. The mounting groove 123 extends laterally and opens toward the slide rail stopper 300. The mounting groove 123 is located below the second grille top reinforcement rib 124. The slide rail stopper 300 also includes a connecting portion 320.

[0105] The connecting portion 320 extends transversely along the second air inlet grille 132 . The connecting portion 320 is protruded toward the mounting groove 123 and is embedded in the mounting groove 123 . The lower limit portion is connected to the bottom of the connecting portion 320 .
