Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit equipment, and in particular to an air conditioning unit filter component. Background Technology

[0002] Air conditioning units utilize various heat and humidity treatment methods and air purification processes to achieve functions such as cooling, heating, dehumidification, humidification, air purification, dust removal, and sterilization, thereby achieving precise control over the indoor environment's temperature, humidity, and cleanliness. To filter dust, air conditioning units often have filters installed at the front end. These filters remove most dust and other foreign objects. After a period of use, the inner walls of the filters tend to accumulate a significant amount of filter material, leading to a decrease in filtration efficiency, requiring replacement or cleaning.

[0003] Currently, filters are installed inside air conditioning units, and their installation structure is complex and cumbersome, making them difficult to disassemble and replace. Moreover, filters are usually composed of multiple non-woven filter bags integrated into one unit, so replacement can only be done by replacing all of the non-woven filter bags as a whole, increasing the cost of use. It is not possible to replace a single non-woven filter bag that has accumulated a lot of dust, resulting in low flexibility. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an air conditioning unit filter component that is easy to install and disassemble, reduces the cost of use and improves the flexibility of replacement.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An air conditioning unit filter assembly includes a casing with an air inlet at the front end and an air outlet at the other end. An internal mounting bracket is provided, with several through slots evenly arranged in the middle of the bracket. Slide rails are slidably connected to the upper and lower sides of the mounting bracket, which are fixed inside the casing. An opening is provided on one side of the casing, through which the mounting bracket movably passes. A bag filter is embedded in each through slot. Rotary shafts are provided on the upper and lower sides of the bag filter, rotatably connected to the mounting bracket. A limiting plate is connected to the front of the bag filter, and the limiting plate movably abuts against the front of the bag filter.

[0007] Preferably, the bag filter includes a non-woven filter bag and a shaping frame. The shaping frame is connected to the front side of the non-woven filter bag, and a positioning groove is provided on the front side of the through groove, into which the shaping frame is embedded.

[0008] Preferably, a rubber frame is provided on the front side of the positioning groove, and the front side of the rubber frame abuts against the rear side of the shaping frame.

[0009] Preferably, the front side of the shaping frame is provided with a first push-pull handle.

[0010] Preferably, the limiting piece is connected to a screw via a thread, the front end of the screw is connected to a knob, and its rear end is in movable contact with the front side of the shaping frame.

[0011] Preferably, a second push-pull handle is provided on one side of the mounting bracket.

[0012] Preferably, a flip frame is rotatably connected to one side of the mounting bracket, and a roller is rotatably connected to the flip frame, which is located below the second push-pull handle.

[0013] Preferably, a centrifugal fan is installed inside the chassis, and the centrifugal fan is located on the side of the mounting bracket away from the air inlet.

[0014] Preferably, a hot and cold coil is provided between the centrifugal fan and the mounting bracket.

[0015] The beneficial effects of this utility model are as follows:

[0016] The air conditioning unit's filter assembly allows for individual disassembly of each bag filter based on the degree of dust accumulation after the mounting bracket is pulled out of the casing through the opening. This eliminates the need to replace all bag filters simultaneously, reducing operating costs and increasing replacement flexibility. During replacement, simply rotate the shaft to disengage the limiting plate from the front side of the bag filter, and the bag filter can be pulled out from the through groove. The operation is convenient, quick, and easy to install and remove. Attached Figure Description

There is no need to replace all bag filters 8 at the same time, which reduces the cost of use and improves the flexibility of replacement. When replacing, simply rotate the shaft 9 to disengage the limiting plate 10 from the front side of the bag filter 8. Then, the bag filter 8 can be pulled out from the through groove 5. The operation is convenient and quick, and it is easy to install and disassemble.

[0030] In order to facilitate the improvement of the installation and positioning accuracy of the bag filter 8, in this embodiment, preferably, the bag filter 8 includes a non-woven filter bag 801 and a shaping frame 802. The shaping frame 802 is connected to the front side of the non-woven filter bag 801. The front side of the through groove 5 is provided with a positioning groove 11, and the shaping frame 802 is embedded in the positioning groove 11.

[0041] The purpose is to flip the rotating frame 16 downwards when the mounting frame 4 needs to be pulled out of the chassis 1, so that the roller 17 contacts the ground, thereby providing support force, ensuring that the mounting frame 4 is evenly stressed when moving, and improving the stability of the movement of the mounting frame 4. After the mounting frame 4 is pushed back into the chassis 1, the rotating frame 16 is flipped upwards for storage.

[0042] To facilitate airflow, in this embodiment, preferably, a centrifugal fan 18 is provided inside the casing 1, and the centrifugal fan 18 is located on the side of the mounting frame 4 away from the air inlet 2;

[0043] The purpose is to drive airflow through the centrifugal fan 18, so that air is drawn in from the air inlet 2 and discharged from the air outlet 3, and the air passes through the bag filter 8 for dust filtration in the middle.

The mounting bracket 4 is pulled out of the casing 1 through the opening 7 by the second push-pull handle 15. Then, each bag filter 8 can be disassembled according to the degree of dust accumulation, without replacing all bag filters 8 at the same time, reducing usage costs and improving replacement flexibility. When replacing the bag filter 8, the knob 14 is turned so that the screw 13 moves along the limiting plate 10, thereby moving the rear end of the screw 13 away from the shaping frame 802. Then, the rotating shaft 9 is turned so that the limiting plate 10 disengages from the front side of the bag filter 8. The bag filter 8 is pulled out of the through groove 5 by the first push-pull handle 803. Finally, the new bag filter 8 is installed into the through groove 5. The operation is convenient and quick, and it is easy to install and disassemble.
