Please refer to FIG. 1 , which is a schematic diagram of the overall structure of the first specific embodiment provided by the present invention.

In the first specific embodiment provided by the utility model, the filter device of the air conditioner mainly includes an air intake grill 1 and a filter screen 2 . It should be noted that the air conditioner in this specific embodiment can be a cabinet unit or a wall-mounted unit or other types of air conditioners, as long as it has an air inlet grille and a filter screen covering the air inlet grille. For the convenience of explanation, the following content and drawings are all descriptions and introductions taking the cabinet machine as an example.

As shown in FIG. 2 , FIG. 2 is a schematic structural diagram of the air inlet grill shown in FIG. 1 .

Among them, the air intake grille 1 is the air intake part of the cabinet, which is generally arranged at the back of the cabinet, and can absorb the external air source into the inside of the cabinet, and then heat or condense it inside the cabinet and exit it from the front of the cabinet. Vent discharge. As the name implies, the structure of the air inlet grille 1 is a fence-like board with multiple spaces, generally a straight or smooth curved surface, because the board has multiple spaces, so it can block some large particles carried in the air , forming the first line of defense for air-conditioning impurity filtration.

As shown in FIG. 3 , FIG. 3 is a schematic diagram of the specific structure of the filter shown in FIG. 1 .

The filter screen 2 is a component mainly used for precision filtration in the air-conditioning cabinet. It is generally the same shape as the air intake grille 1, and is also in the shape of a straight face or a smooth curved surface. It is installed inside the air intake grille 1 and is closely attached to it. Because the filter screen 2 itself is mesh-shaped, and the mesh is fine and evenly distributed, it can filter out impurities such as dust and harmful substances in the air with small particle diameters while the air is circulating; and because the filter screen 2 is in the manufacturing process Antibacterial agents and antifungal agents are generally mixed in, so the filter screen 2 can also be antibacterial and antifungal, forming the second line of defense for air-conditioning impurity filtration.

As shown in FIG. 4 and FIG. 5 , FIG. 4 is an enlarged schematic diagram of partial details of the intake grill shown in FIG. 2 ; FIG. 5 is an enlarged schematic diagram of partial details of the filter screen shown in FIG. 3 .

The two lines of defense for air-conditioning impurity filtration need to work at the same time to effectively achieve the effect of air filtration. For this reason, an inlet is generally provided on the air intake grille 1, and the filter 2 can be inserted through the inlet, and then pushed forward until the filter is finished. The net 2 is closely attached to the air intake grill 1. In order to ensure that the connection relationship between the filter screen 2 and the air inlet grille 1 is close, grooves 3 are provided on the top and bottom of the inlet of the air inlet grille 1 in this embodiment, and correspondingly, on the filter screen 2 and Elastic arms 4 are provided on the top and bottom of the side frame corresponding to the entrance of the intake grill 1 , and bosses 5 are provided on the side walls of the elastic arms 4 . Because the dimensional design of the groove 3 and the dimensional design of the boss 5 can ensure that the boss 5 and the groove 3 are closely matched, therefore, if the filter screen 2 is inserted into the air intake grill 1, then the boss 5 and the groove 3 With cooperation, the filter screen 2 can be firmly fixed on the intake grille 1.

Here, preferably, the groove 3 is a hemispherical groove, and correspondingly, the boss 5 is also a hemispherical boss. When the spherical boss 5 cooperates with the groove 3, the smooth curve of the spherical shape can be used to reduce the extrusion stress when the two are in contact, which improves the service life of the device to a certain extent. Certainly, the groove 3 may also be a groove of other shapes, such as a rectangular groove, and correspondingly, the boss 5 may also be a rectangular boss.

As we all know, the filter screen of the air conditioner needs to be replaced and cleaned immediately, which requires that the filter screen 2 can be easily installed and disassembled, and the two operations are inseparable from the action of the elastic arm 4 .

Elastic arm 4 is a kind of flexible member with elasticity and return function, and it can rotate at a certain angle with the joint point of its own root and filter screen 2 as the fulcrum, and can also carry out deformation and return to a certain degree at the same time, and Its effect is reflected in the installation and disassembly process of the utility model.

The style grill 1 fits snugly. At this time, the operator continues to push the filter screen inward, so that the elastic arm 4 is deformed toward the middle position of the filter screen 2, and then drives the boss 5 arranged on the side wall of the elastic arm 4 to also move inward for a certain period. The displacement makes the boss 5 able to fit the boss 5 into the groove 3 provided on the intake grill 1 . After the boss 5 falls into the groove 3, the elastic arm 4 immediately starts to return, and the boss 5 is tightly pressed against the groove 3, so that the two are closely matched, and finally the filter screen 2 and the air inlet grille 1 fixed together to complete the installation operation.

Continuing from the above, when the filter screen 2 is disassembled, it is necessary to perform steps opposite to the above-mentioned installation process. First, the operator pulls the filter screen 2 outwards, so that the boss 5 arranged on the side wall of the elastic arm 4 moves to the middle position of the filter screen 2, and this displacement makes the connection between the boss 5 and the groove 3 disengaged. Then the operator starts to pull the filter screen 2 outwards, so that the elastic arm 4 returns to the normal position, and finally the whole filter screen 2 is pulled out from the air intake grille 1 to complete the disassembly operation.

In summary, the filter device of the air conditioner provided by the utility model, by setting the groove 3 on the air intake grille 1, setting the elastic arm 4 on the filter screen 2, and then setting the boss 5 on the elastic arm 4 Finally, the filter screen 2 and the air intake grille 1 are tightly fixed through the cooperation of the boss 5 and the groove 3, thereby avoiding the misalignment of the filter screen 2, failure to work normally, and air leakage due to factors such as mechanical vibration and external force interference. And other issues. In addition, the filter device of the cabinet machine provided by the utility model can also install and disassemble the filter net 2 as required.

In addition, considering that the filter screen 2 is generally symmetrical in structure, its front and rear ends cannot be distinguished from the appearance, and when the filter screen 2 is installed, there may be misoperations in which the front and rear ends are reversed. In view of this, the utility model is provided with identification arrow 6 at the more obvious position on the filter screen 2, and the indication direction of this identification arrow 6 is the correct installation and disassembly direction, thereby avoiding the situation of misoperation.
