[0019] The utility model is further described in detail below through specific implementation methods:

[0020] like Figure 2 and Figure 4 As shown, an embodiment of the utility model proposes a filter installation structure, which is arranged on an air duct to install a filter assembly, including a support member 1, wherein the support member 1 is fixedly arranged in the air duct and has an installation space for installing the filter assembly in the middle thereof and a mounting port connected to the installation space on one side thereof, and the mounting port is used for the filter assembly to slide into or slide into the installation space.

[0021] The filter installation structure is mainly composed of a support member 1. The filter assembly 6 is slid into the installation space from the installation opening, and then the support member 1 is fixed in the air duct. The structure is simple and the assembly of the filter assembly 6 is completed quickly.

[0022] The structure of the support member 1 will be further detailed below.

[0023] The support member 1 is an annular unclosed structure, and the installation opening is the opening of the annular unclosed structure; its structural design is simple and can realize the installation of the filter assembly 6.

[0024] In order to improve the installation stability of the filter assembly 6, the inner side wall of the support member 1 is provided with a slot 2 along its arrangement path, and the edge of the filter assembly slides into the slot 2 for installation. The slot 2 is used to install and position the filter assembly, thereby improving the installation stability of the support member 1 on the filter assembly 6.

[0025] The slot 2 is formed by bending two sides of the support member 1 that are arranged opposite to each other along its arrangement path, and the processing method is convenient and quick.

[0026] According to the shape design of the filter assembly 6, the support member 1 is "U"-shaped, and the sides forming the slot 2 are all broken at the bend. The sides forming the slot 2 are all broken at the bend to allow the sides to have a certain amount of space at the rotation, so that the sides can be well formed at the rotation.

[0027] In this embodiment:

[0028] Since the air duct is a square tube, the filter assembly 6 is designed as a square block, and the support member 1 is designed in a "U" shape for good matching; the shape design of the support member 1 is also adjusted to match the shape changes of the filter assembly 6 and the air duct.

[0029] The support member 1 can be a strip of metal block, bend its two ends to form a "U" shape, then cut it at the two side connections at both ends to break it, then bend the two side connections at both ends, and then form a slot 2 inside the "U"-shaped support member 1; its structure is simple and the processing method is relatively simple, and the manufacturing cost is low. After the filter assembly 6 is installed in the support member 1, the filter assembly 6 can be limited and fixed from three sides to ensure that the filter assembly 6 has sufficient installation stability in the support member 1.

[0030] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, an engineering air duct comprises an air duct body 3 and the filter installation structure in the previous embodiment; an assembly opening 4 is opened on the side wall of the air duct body 3, and the support member 1 slides into the air duct body 3 from the assembly opening 4 and then fits and fixes it, and the installation opening is placed in the assembly opening 4.

[0031] In this embodiment:

[0032] The air duct body 3 is a square tube, that is, the air duct in the previous embodiment; the assembly port 4 is opened on the side wall at one end of the air duct body 3, and preferably the assembly port 4 is opened on the side wall at the air inlet end of the air duct body 3, so that the filter surface of the installed filter assembly 6 faces the outside of the air duct body 3, which is convenient for cleaning dust and the like adhering to the filter surface of the filter assembly 6 when used for a long time.

[0033] The opening of the assembly port 4 makes it easy for the support member 1 equipped with the filter assembly 6 to be easily slid into the air duct body 3, and the installation port of the support member 1 is located in the assembly port 4, that is, both ends of the support member 1 are located in the assembly port 4, so that the assembly port 4 can limit the movement of the support member 1 along the axial direction of the air duct body 3, thereby improving the stability of the support member 1 in the air duct body 3.

[0034] In order to enable the support member 1 to be accurately installed in the air duct body 3 , the center line of the installation opening coincides with the center line of the assembly opening 4 .

[0035] In order to further improve the installation stability of the filter assembly 6, as Figure 1 , Figure 2 as well as Figure 3 As shown, according to another embodiment of the utility model, the engineering air duct further includes a sealing plate 5, and the sealing plate 5 is detachably connected to the air duct body 3 to seal the assembly port 4.

[0036] In this embodiment:

[0037] There are multiple mounting holes evenly distributed on the edge of the sealing plate 5, and screws connected to the duct body 3 are installed at the mounting holes to ensure that the sealing plate 5 is stably connected to the duct body 3 to seal the assembly port 4; after the sealing plate 5 seals the assembly port 4, it seals the mounting port of the support member 1 to stably limit the filter assembly 6 in the support member 1 to improve the installation stability of the filter assembly 6.

[0038] In order to facilitate the operation of the sealing plate 5 by the staff when installing or disassembling the sealing plate 5, at least one end of the sealing plate 5 is bent away from the air duct body 3. In this embodiment, one end of the sealing plate 5 is bent away from the air duct body 3 to make it easier for the staff to hold the sealing plate 5, which is more convenient when installing or disassembling the sealing plate 5.

[0039] The specific installation process in this embodiment is:

[0040] After the support member 1 is processed, the support member 1 is slid into the air duct body 3 from the assembly opening 4, and then the support member 1 is fixedly connected to the air duct body 3 by welding;

[0041] Then, the filter assembly 6 is slid from the installation opening 4 into the slot 2 in the support member 1 to be fixed in position;

[0042] The sealing plate 5 is then fixedly connected to the assembly opening 4 of the air duct body 3 by a plurality of screws to seal the assembly opening 4 and complete the installation.

[0043] When the filter assembly 6 needs to be disassembled later, the sealing plate 5 is disassembled to remove the filter assembly 6 from the support member 1 .

[0044] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, the central air conditioner includes an engineering air duct of the previous embodiment, which can first filter the air entering the central air conditioner, and its structure is simple and can stably install the filter component 6, and the filter component 6 is also convenient in the subsequent disassembly and installation process.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
