A filter assembly and an air conditioner according to an embodiment of the present utility model will be described with reference to fig. 1 to 6.

As shown in fig. 2 to 5, the filter assembly according to the embodiment of the present utility model includes: the electrostatic filter element 1, the filter cover 2, the fixing seat 3 and the carbon brush 4. The static filter core 1 is arranged on the filter cover 2, a through hole 24 is formed in the side wall of the filter cover 2, the fixing seat 3 is arranged on the outer side wall of the filter cover 2, the carbon brush 4 comprises a carbon brush head 41 and a lead 42 which are connected, the lead 42 is arranged on the outer side of the filter cover 2 and is connected with the fixing seat 3, and the carbon brush head 41 is arranged on the fixing seat 3 and penetrates through the through hole 24.

According to the filter assembly provided by the embodiment of the utility model, the fixing seat 3 is arranged on the outer side of the filter cover 2, so that the lead wire 42 and the carbon brush head 41 can be installed on the filter cover 2 through the fixing seat 3 to fix the lead wire 42 and the carbon brush head 41, an operator can conveniently install the carbon brush 4 on the filter cover 2, and the carbon brush 4 is installed more reliably. Therefore, the filter assembly of the embodiment of the utility model has reasonable structural design, is convenient for assembling the carbon brush head 41 and the lead wire 42, and the carbon brush 4 after being installed is not easy to loosen, so that the reliability is higher.

Optionally, as shown in fig. 3 and fig. 4, the fixing base 3 includes a fixing body 31 and a clamping portion 32 that are connected, the fixing body 31 is connected to the filter cover 2, a mounting hole 312 is formed in the fixing body 31, the carbon brush head 41 is sequentially penetrated through the mounting hole 312 and the through hole 24, and the lead 42 is clamped on the clamping portion 32. Because the mounting holes 312 are formed in the fixing body 31, the carbon brush head 41 can be penetrated and clamped in the mounting holes 312, so that the carbon brush head 41 can be fixed, the carbon brush head 41 is prevented from moving relative to the filter cover 2, and the reliability of mounting the carbon brush head 41 is improved.

Alternatively, as shown in fig. 3, the clamping portion 32 is located at the upper end of the fixing body 31, the clamping portion 32 and the outer side wall of the filter cover 2 enclose a limiting cavity 321, and the lead 42 is clamped in the limiting cavity 321. It can be understood that the lead wire 42 is threaded through the limiting cavity 321 and is fixed relative to the limiting cavity 321, and because the lead wire 42 is limited by the limiting cavity 321, the problem that the carbon brush head 41 shakes relative to the filter cover 2 under the action of external force can be reduced, and the reliability of the installation of the carbon brush head 41 and the lead wire 42 is improved.

Alternatively, as shown in fig. 3 and 6, the fixing body 31 is detachably connected with the filter cover 2, so that the fixing seat 3 and the filter cover 2 can be manufactured separately, with low cost and convenient installation. For example, one of the fixing body 31 and the filtering cover 2 is provided with a clamping hook 21, and the other is provided with a clamping groove 311, and the clamping hook 21 is clamped in the clamping groove 311. It can be appreciated that, because the fixing base 3 is connected with the filtering cover 2 through the clamping connection, the fixing base 3 can be conveniently installed on the filtering cover 2 by an operator, and the cost is lower.

Alternatively, as shown in fig. 3 and 6, the fixing base 3 is provided with a spring plate 33, and the spring plate 33 and the fixing body 31 are arranged at intervals to form a clamping groove 311.

In some embodiments, as shown in fig. 5, the free end of the carbon brush head 41 (the end of the carbon brush head 41 facing away from the lead wire 42) extends obliquely toward the direction facing away from the electrostatic filter element 1. Specifically, in the direction from the outer end of the mounting hole 312 to the inner end of the mounting hole 312, the mounting hole 312 extends in a direction away from the electrostatic filter element 1, the carbon brush head 41 is provided to pass through the mounting hole 312, and the length direction of the carbon brush head 41 coincides with the axial direction of the mounting hole 312. It is to be understood that the mounting holes 312 are arranged obliquely downward so as to guide the mounting of the carbon brush head 41. In addition, since the carbon brush head 41 is arranged obliquely downwards, the carbon brush head 41 can be conveniently discharged to charge dust in the air, and the dust adsorption effect of the filter assembly is improved.

For example, the included angle α may be 40 degrees, 45 degrees, or 50 degrees. The inventors of the present utility model have found through experimental studies that when the included angle α satisfies the above range, the dust adsorbing effect of the filter assembly can be further improved.

In some embodiments, as shown in fig. 2, the number of fixing bases 3 is plural, the plurality of fixing bases 3 are arranged at intervals along the circumferential direction of the outer sidewall of the filter cover 2, the number of carbon brushes 4 is plural, and the plurality of carbon brushes 4 are in one-to-one correspondence with the plurality of fixing bases 3. Because the carbon brushes 4 are uniformly arranged along the circumferential direction of the filter cover 2, dust near the filter cover 2 can be uniformly charged, the dust adsorption effect is further improved, and the filtering performance is better.

Optionally, as shown in fig. 2, the filter assembly further includes a distribution box 5, and the mating box is disposed on one side of the filter cover 2 in the length direction (i.e., the left-right direction of the filter cover 2 in fig. 2) and is disposed adjacent to the electrostatic filter element 1, and the leads 42 of the plurality of carbon brushes 4 are led out from the distribution box 5.

In some embodiments, as shown in fig. 3 and 4, the outer side wall of the filter cover 2 is provided with a wire shielding plate 23, a wire channel is defined between the wire shielding plate 23 and the outer side wall of the filter cover 2, and the lead 42 can be arranged in the wire channel, so that the lead 42 can be placed, and the probability of damage to the lead 42 due to collision and extrusion during assembly is reduced.

As shown in fig. 1 and 2, an air conditioner according to another embodiment of the present utility model includes a filter assembly and a housing 6. The filter assembly is the filter assembly of the utility model, and the filter assembly is arranged at the upper end of the shell 6.
