The parameters associated with the second sloped wall 1221 are described in more detail below, and the parameters associated with the first sloped wall 1215 can be referenced to the parameters associated with the second sloped wall 1221.

Referring to fig. 6 and 8, generally, the filter screen 122 itself is a flexible structure, and the fixing strip 1222 is disposed on the filter screen 122, so that the fixing strip 1222 can support, enhance the overall strength of the filter screen 122, and prolong the service life of the filter screen 122. Thus, the filter screen 122 is not easily deformed, and the filter screen 122 is effectively ensured to continuously perform the filtering and purifying operation.

Specifically, referring to fig. 6 and 8, in the present embodiment, a plurality of filter strips 1223 are disposed on the filter screen 122, the plurality of filter strips 1223 are distributed side by side, a length direction of the fixing strip 1222 is parallel to a side by side direction of the plurality of filter strips 1223, and the fixing strip 1222 is connected to the plurality of filter strips 1223 at the same time. Like this, can strengthen the joint strength between a plurality of filter strips 1223, a plurality of filter strips 1223 are difficult to take place deformation, can continuously play the filtration purification effect.

Alternatively, the fixing strip 1222 and the filter strip 1223 may be connected by welding, bonding, or the like.

In this embodiment, the number of the fixing bars 1222 is at least two, the at least two fixing bars 1222 are parallel to each other, and the at least two fixing bars 1222 are connected to the plurality of filter bars 1223, which can further enhance the connection strength between the plurality of filter bars 1223.

In this embodiment, the filter screen 122 is further provided with a first side wall 1224 and a second side wall 1225, the first side wall 1224, a second inclined wall 1221 and the second side wall 1225 are sequentially connected, and the first side wall 1224 and the second side wall 1225 are vertically arranged, so that the second inclined wall 1221 can be formed by cutting one corner of the filter screen 122 with a rectangular structure, the production and the manufacture are more convenient, and the production efficiency can be improved.

In this embodiment, the length direction of the second sidewall 1225 is parallel to the length direction of the fixing bar 1222.

It can be understood that the side-by-side distribution direction of the plurality of filter strips 1223, the length direction of the fixing strip 1222, and the length direction of the second side wall 1225 are parallel to each other, so that the fixing strip 1222 is not affected by interference of the second side wall 1225 during the extending process, and the fixing strip 1222 can more easily connect the plurality of filter strips 1223 together at the same time, thereby enhancing the connection strength between the plurality of filter strips 1223.

In the present embodiment, the second inclined wall 1221 is formed by cutting off a portion of each of the first side wall 1224 and the second side wall 1225, and since the screen 122 has a rectangular structure before being chamfered, it can be inferred that the cut-off portion of the screen 122 has a right triangle shape.

The inventor researches and discovers that if the distance between two adjacent fixing bars 1222 is too large, the overall strength of the filter screen 122 is reduced. If the distance between two adjacent fixing strips 1222 is too small, the filtering effect of the plurality of filter strips 1223 is affected. Therefore, it is necessary to limit the distance between the adjacent two fixing bars 1222 within a certain range.

In addition, the inventor has found that if the length of the right-angle side of the cut-off portion of the filter screen 122 is too long, a large amount of area of the filter screen 122 is lost, which affects the filtering effect of the filter screen 122, and the service life of the filter screen 122 is shortened accordingly. If the length of the right-angled side of the cut-off portion of the filter screen 122 is too short, the cutting position is not accurately determined, and the manufacturing process becomes more complicated. Therefore, it is necessary to limit the length of the right-angle side of the cut-off portion of the screen 122 to a certain range.

After considering the overall strength, filtering effect and manufacturing process of the filter screen 122, the present embodiment defines the distance between two adjacent fixing bars 1222 and the length of the right-angled side of the cut-off portion of the filter screen 122 at the same time.

Specifically, in conjunction with FIG. 8, in the present embodiment, the first side wall 1224 and the second inclined wall 1221 form a first included angle α, where α < 90 ° < 180 °, i.e., the first included angle α is an obtuse angle. The second side wall 1225 and the second inclined wall 1221 form a second included angle β, where β is greater than 90 ° and less than 180 °, i.e., the second included angle β is also obtuse. The distance between two adjacent fixing bars 1222 is a. The second sloped wall 1221 has a length B.

It is understood that B sin (α -90 °) may be understood as one of the right-angled sides of the right-angled triangle where the screen 122 is cut away. B sin (β -90 °) may be understood as the other right-angled side length of the right-angled triangle from which the screen 122 is cut.

Taking fig. 8 as an example, the length indicated by X in fig. 8 is equal to the length indicated by B × sin (α -90 °). The length denoted by Y in fig. 8 is equal to the length denoted by B x sin (β -90 °).

In the present embodiment, the relationship between the distance a between two adjacent fixing bars 1222 and the length B of the second inclined wall 1221 is:

0.5 × B × sin (α -90 °) A ≦ 2 × B × sin (α -90 °), and/or 0.5 × B × sin (β -90 °) A ≦ 2 × B × sin (β -90 °).

Thus, the overall strength and filtering effect of the filter screen 122 can be ensured, and the second inclined wall 1221 can be formed by convenient processing.

Optionally, the two inequalities may be satisfied simultaneously, or only one of the inequalities may be satisfied.

In this embodiment, the first included angle α is equal to the second included angle β. That is, in the present embodiment, the right triangle of the filter screen 122 is cut off is an isosceles right triangle. Thus, the length of the cut portion of the first sidewall 1224 is equal to the length of the cut portion of the second sidewall 1225, which is convenient for manufacturing and does not affect the filtering effect of the cut filter screen 122.

In summary, the present embodiment provides a filter assembly 12, a fresh air device 1 and an air conditioner, the matching structure of the first inclined wall 1215 and the second inclined wall 1221 can indicate the direction of installing the filter screen 122 by the worker, so as to effectively improve the problem that the filter screen 122 is easy to be installed reversely, the fixing strip 1222 can improve the overall strength of the filter screen 122, and prolong the service life of the filter screen 122.
