In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0053] Figure 1 is a schematic front view of an air conditioner indoor unit according to an embodiment of the utility model, as shown Figure 1 As shown, and refer to Figure 2-13 The embodiment of the utility model provides a support assembly of an air conditioner indoor unit, the support assembly includes a vertically arranged support column 100, the support column 100 is arranged at a distance from the front side of the front end of the rear panel 900 of the air conditioner indoor unit, the lower end of the support column 100 is used to be fixedly connected to the base 500 of the air conditioner indoor unit, and the upper end of the support column 100 is used to be fixedly connected to the air duct assembly 300 of the air conditioner indoor unit.

[0054] There are at least two support columns 100 , which are spaced apart from each other along the width direction of the air conditioner indoor unit.

[0055] The indoor air conditioner can be a split type indoor cabinet air conditioner or an integrated mobile indoor cabinet air conditioner. The cabinet air conditioner usually has a large height-to-width ratio and poor overall stability.

[0056] The rear panel 900 is usually made of plastic and is processed by injection molding. The rear panel 900 is usually U-shaped with an opening facing forward, and the bottom end of the rear panel 900 is fixedly connected to the base 500. The front panel is usually U-shaped with an opening facing backward, and is surrounded by the rear panel 900 to form an air conditioner housing. The front panel usually does not support the air conditioner, and the support of the air conditioner is mainly borne by the base 500 and the rear panel 900. The air duct assembly 300 and other functional modules 700 can be fixedly connected to the rear panel 900, and other functional modules 700 may include a water washing module, a fresh air module, a humidification module, etc. The air duct assembly 300 and each functional module 700 are usually fixedly connected to the rear panel 900 at the rear end and / or the left and right ends, and the front end extends out of the front end of the rear panel 900 to form a front cantilever structure, which further deteriorates the stability of the whole machine. When the user touches the button on the air conditioner, the air conditioner is prone to shake back and forth, and the user experience is poor.

[0057] In this embodiment, in order to improve the stability of the air conditioner, a technical solution of setting a support assembly is proposed. Specifically, the support assembly includes a support column 100, which is arranged at intervals on the front side of the front end of the rear panel 900, the lower end of which is fixedly connected to the base 500, and the upper end of which is fixedly connected to the air duct assembly 300. The lower end and the upper end of the support column 100 are both located at the front side of the front end of the rear panel 900, and have a preset distance from the front end of the rear panel 900. In this way, the support column 100 can directly support the air duct assembly 300 at the front part of the air duct assembly 300 at the front end of the rear panel 900, at least forming an effective and firm support for the front overhang part of the air duct assembly 300, thereby improving the stability of the air conditioner.

[0058] The front overhang of the air duct assembly 300 is connected to the base 500 through the support column 100. The support column 100 can also share part of the gravity of the air duct assembly 300, thereby improving the stability of the air conditioner.

[0059] On the other hand, since the support column 100 can share part of the gravity of the air duct assembly 300, the amount of material used in the rear panel 900 or the strength of the reinforcing ribs can be reduced, thereby reducing the weight and manufacturing cost of the air conditioner.

[0060] When the support assembly is only provided with one support column 100, the support column 100 generally needs to be provided in the middle of the air duct assembly 300 along the left-right direction to avoid unbalanced loading, but this may affect the air outlet of the air duct assembly 300, or may affect the normal operation of other functional modules 700 between the air duct assembly 300 and the base 500.

[0061] like Figure 1 As shown, the width direction of the air conditioner indoor unit is as follows Figure 1The support assembly may include two or more support columns 100, and each support column 100 is arranged at intervals along the left-right direction to avoid affecting the air outlet of the air duct assembly 300, avoid affecting the normal operation of other functional modules 700 between the air duct assembly 300 and the base 500, and can further strengthen the support for the air duct assembly 300.

[0062] It should be noted that the base 500, rear panel 900 and air duct assembly 300 and other components involved in this embodiment are all characteristics of the use environment of this product. When applied to practice, this support assembly can be separated from the above components and independently produced and sold.

[0063] It should be understood that in this embodiment, since the air duct assembly 300 is located on the upper side of other functional modules 700, the upper end of the support column 100 is configured to be fixedly connected to the air duct assembly 300. In other embodiments of the utility model, when other functional modules 700 are located on the upper side of the air duct assembly 300, the upper end of the support column 100 is fixedly connected to the functional module 700.

[0064] In some embodiments of the support assembly of the present invention, Figure 2 As shown, the upper end of the support column 100 is used to be fixedly connected to the front end of the air duct assembly 300 .

[0065] In this embodiment, the support column 100 is fixedly connected to the front end of the air duct assembly 300. On the one hand, it can ensure that the center of gravity of the front overhang of the air duct assembly 300 is behind the support column 100, so as to more stably support the air duct assembly 300. On the other hand, the operating space on the front side of the air conditioner is large, which is convenient for disassembly and assembly of the support column 100. During installation, after the air duct assembly 300 is installed on the rear housing, the upper end of the support column 100 can be directly installed on the air duct assembly 300 from the front side. During disassembly, the support column 100 can be directly disassembled and taken out forward.

[0066] In some embodiments of the support assembly of the present invention, Figure 2 As shown, in the front-to-back direction, the minimum distance L between the support column 100 and the rear panel 900 is greater than or equal to 40 mm.

[0067] When the minimum distance between the support column 100 and the rear panel 900 is too small, the supporting effect on the air duct assembly 300 is poor. The larger the minimum distance, the more the support column 100 can support the air duct assembly 300 and other functional modules 700 in the front-to-back direction, thereby improving the stability of the air conditioner in the front-to-back direction.

[0068] Preferably, the minimum distance between the support column 100 and the rear panel 900 is 50-55 mm, so that the air conditioner has the best stability in the front-to-back direction while keeping the air conditioner compact in the front-to-back direction.

[0069] In some embodiments of the support assembly of the present invention, Figure 7 As shown, the support column 100 includes a column body 110, and the column body 110 includes a front vertical plate 111 and two side vertical plates 112. The front vertical plate 111 extends along the width direction of the air conditioner indoor unit, and the two side vertical plates 112 extend backward from the two lateral edges of the front vertical plate 111 respectively.

[0070] In this embodiment, the column 110 is a sheet metal part, and the side panels 112 are formed by bending backwards from the left and right edges of the front panel 111, which can enhance the structural strength of the column 110 to form a good support for the air duct assembly 300 and each functional module 700.

[0071] In some embodiments of the support assembly of the present invention, Figure 4 and Fig.10 As shown, the support column 100 further includes an air duct connection structure 130 located at the upper end of the column body 110 , and the air duct connection structure 130 includes a first connection hole 131 and a first limiting hole 132 .

[0072] The first connection hole 131 is located on the front vertical plate 111. The first limiting hole 132 is located on the front vertical plate 111. The first limiting hole 132 is a non-circular hole, and its hole wall extends forward from the front surface of the front vertical plate 111 to form a boss.

[0073] An air duct fixing structure 310 is disposed on the air duct assembly 300 . The air duct fixing structure 310 includes a first fixing column 311 protruding forward and a first limiting column 313 protruding forward.

[0074] The first fixing column 311 is provided with a second connection hole 312 corresponding to the first connection hole 131 . The first limiting column 313 is plug-inly connected in the first limiting hole 132 .

[0075] In this embodiment, the first connection hole 131 and the first limiting hole 132 are both arranged front and back. The operating space at the front of the air conditioner is large, and during installation, the support column 100 can be conveniently installed from the front side of the air duct assembly 300, which is very convenient.

[0076] The second connection hole 312 may be a threaded hole. When the first connection hole 131 is aligned with the second connection hole 312 , a screw may be screwed directly from front to back.

[0077] The first limiting hole 132 can be a rectangular hole, and the first limiting column 313 can be a rectangular column. When the first limiting column 313 profile sleeve is connected to the first limiting hole 132, it can limit the support column 100 so that the support column 100 is at the correct angle and position, so that the first connecting hole 131 is automatically aligned with the second connecting hole 312, and the other mounting holes of the support column 100 are automatically aligned with the corresponding fixing holes, thereby improving the installation efficiency.

[0078] On the other hand, when the installation is completed, the first limiting column 313 can also limit the first limiting hole 132 in the up and down and left and right directions to reduce or avoid the shaking of the support column 100, thereby firmly supporting the air duct assembly 300 and each functional module 700.

[0079] In some embodiments of the support assembly of the present invention, Figure 4 and Fig.10 As shown, the air duct connection structure 130 further includes an upper folding plate 133, which is formed by folding backward from the upper edge of the front vertical plate 111. The air duct fixing structure 310 further includes a first limiting rib 314 protruding forward and extending in the transverse direction, which is located on the upper side of the upper folding plate 133 and is fitted or gap-matched with the upper folding plate 133.

[0080] In this embodiment, during installation, the first limiting rib 314 can stop the upper folding plate 133, thereby guiding the position of the support column 100, and facilitating the rapid alignment of the first limiting hole 132 with the first limiting column 313. During use, the first limiting rib 314 can limit the upper folding plate 133 in the up and down directions, thereby limiting the upper end of the support column 100, and reducing or preventing the upper end of the support column 100 from shaking up and down.

[0081] In some embodiments of the support assembly of the present invention, Figure 4 and Fig.10 As shown, the first limiting hole 132 is located at the lower side of the first connecting hole 131. The air duct fixing structure 310 also includes a second limiting rib 315 protruding forward, which is vertically arranged and located at one side of the first fixing column 311 and the first limiting column 313 in the lateral direction. The upper and lower ends of the second limiting rib 315 are respectively fixedly connected to the first fixing column 311 and the first limiting column 313 through the connecting rib 316. The second limiting rib 315 is two and oppositely arranged in the lateral direction, and is respectively fitted or gap-matched with the vertical plates 112 on both sides.

[0082] In this embodiment, the second limiting ribs 315 and the connecting ribs 316 may be used to improve the structural strength of the first fixing column 311 and the first limiting column 313 .

[0083] During installation, the two second limiting ribs 315 can guide the two side vertical plates 112, so as to quickly align the first limiting hole 132 with the first limiting column 313. During use, the two second limiting ribs 315 can limit the two side vertical plates 112 in the left and right directions, thereby limiting the upper end of the support column 100, reducing or preventing the upper end of the support column 100 from shaking left and right.

[0084] In some embodiments of the support assembly of the present invention, the support column 100 is formed by a sheet metal stamping process.

[0085] The structural features of the support column 100, such as the bending structures, connecting holes and positioning holes, are all processed by sheet metal stamping technology, which can improve the processing accuracy of the structural features on the one hand, and improve the processing efficiency and reduce the production cost on the other hand.

[0086] In some embodiments of the support assembly of the present invention, Figure 2 and Figure 8 As shown, from bottom to top, the support column 100 includes a first vertical section 191, a bending section 192, and a second vertical section 193 arranged in sequence, and the front vertical plate 111 in the second vertical section 193 is located at the rear side of the front vertical plate 111 in the first vertical section 191. The air duct connection structure 130 is located on the second vertical section 193.

[0087] In this embodiment, the support column 100 has a backward bending section 192. It should be understood that the front side of the air duct assembly 300 is usually an air outlet, and the air outlet is usually provided with air guides such as grilles and air guide plates, which have a certain thickness. By providing the bending section 192, the air guides can be avoided to avoid interference.

[0088] In this embodiment, the lower end of the support column 100 is located in front of the upper end. Figure 2 As shown, the base 500 , the upper and lower ends of the support column 100 and the front end of the rear shell form a triangular support structure, which can further improve the firmness of the support for the air duct assembly 300 .

[0089] In some embodiments of the support assembly of the present invention, Figure 5 and Figure 12-13 As shown, the support column 100 further includes a base connection structure 150 located at the lower end of the column body 110 , and the base connection structure 150 includes a third connection hole 151 and a second limiting hole 152 .

[0090] The third connection hole 151 is located on the front vertical plate 111 . The second limiting hole 152 is located on the front vertical plate 111 and is located below the third connection hole 151 .

[0091] A base fixing structure 510 is disposed on the base 500 , and the base fixing structure 510 includes a second fixing column 512 extending forward and backward and a second limiting column 513 protruding forward.

[0092] The second fixing column 512 is provided with a fourth connection hole 514 corresponding to the third connection hole 151 . The second limiting column 513 is inserted into the second limiting hole 152 .

[0093] In this embodiment, the third connection hole 151 and the second limiting hole 152 are both arranged front and back. The operating space at the front of the air conditioner is large, and during installation, the support column 100 can be easily installed from the front side of the base 500, which is very convenient.

[0094] The fourth connection hole 514 may be a threaded hole, and when the third connection hole 151 is aligned with the fourth connection hole 514 , a screw may be screwed directly from front to back.

[0095] During installation, the second limiting column 513 can guide the second limiting hole 152. When the second limiting hole 152 is inserted on the second limiting column 513, the third connecting hole 151 is automatically aligned with the fourth connecting hole 514, thereby improving installation efficiency.

[0096] On the other hand, when the installation is completed, the second limiting column 513 can also limit the second limiting hole 152 in the up and down and left and right directions to reduce or avoid the shaking of the support column 100, thereby firmly supporting the air duct assembly 300 and each functional module 700.

[0097] In this embodiment, the third connection hole 151 is located above the second limiting hole 152. The base 500 is usually placed on the ground, which is at a low position and is not convenient for screwing. The third connection hole 151 is located above the second limiting hole 152, which can raise the height of the third connection hole 151 and facilitate half screwing.

[0109] The sixth connection hole 716 may be a threaded hole, and when the fifth connection hole 171 is aligned with the sixth connection hole 716 , a screw may be directly driven from front to back.

[0110] During installation, the third limiting column 713 can guide the third limiting hole 172. When the third limiting hole 172 is inserted on the third limiting column 713, the fifth connecting hole 171 is automatically aligned with the sixth connecting hole 716, thereby improving installation efficiency.

[0111] On the other hand, when the installation is completed, the third limiting column 713 can also limit the third limiting hole 172 in the up and down and left and right directions to reduce or avoid the shaking of the support column 100, thereby firmly supporting each functional module 700.

[0112] In this embodiment, the third limiting hole 172 can be a non-circular hole, such as a rectangular hole, and the third limiting column 713 can be a rectangular column. When the third limiting column 713 profile is inserted into the third limiting hole 172, the third limiting column 713 can also limit the third limiting hole 172 in the up and down and left and right directions, reducing or avoiding the shaking of the support column 100, thereby firmly supporting each functional module 700.
