The high-efficiency air filter is mainly used for trapping particle dust and various suspended matters above 0.5 um. The wood frame aluminum alloy filter material is formed by adopting superfine glass fiber paper as a filter material, adopting offset paper, an aluminum film and other materials as a partition board, and gluing the partition board with a wood frame aluminum alloy, and adopting special silicon rubber, so that the wood frame aluminum alloy filter material is odorless, has no hardening on the surface, has no cracks for a long time, has stable chemical properties, is corrosion-resistant, can absorb the stress generated by expansion with heat and contraction with cold without cracking, has moderate hardness, and has good elastic recovery. Has the characteristics of high filtering efficiency, low resistance, large dust holding capacity and the like.

Referring to fig. 5, in some embodiments, the vent hole 102 of the wind-guiding ring 100 is an elliptical hole, a major axis of the elliptical hole is L, a minor axis of the elliptical hole is H, and a length ratio of the major axis L to the minor axis H of the elliptical hole is 1.1-1.5. The diameter of the base circular portion 103 is equal to the length of the minor axis H of the elliptical hole, and the length of the major axis L longer than the minor axis H is the length expanding outward from the base circular portion 103, that is, the depth of the counterbore portion 104. Under the condition that the diameter of the base circle part 103 is not changed, namely the length of the minor axis H of the elliptical hole is not changed, the larger the length ratio of the major axis L to the minor axis H of the elliptical hole is, the longer the length of the major axis L of the elliptical hole is, the larger the area of the vent hole 102 is, the larger the air intake area of fresh air is, and the larger the fresh air volume is. The internal structure of the fresh air module 200 has a limited size, if the length ratio of the long axis L to the short axis H of the elliptical hole is too large, other structures of the fresh air module 200 are affected, and if the length ratio of the long axis L to the short axis H of the elliptical hole is too small, the increased fresh air volume is not obvious. Through continuous design and experiments, the length ratio of the long axis L to the short axis H of the elliptical hole is 1.1-1.5, so that the fresh air volume can be effectively increased, and the influence on other structures of the fresh air module 200 can be reduced.

Referring to fig. 5, in some embodiments, the maximum length of the blade of wind wheel 303 projected along the axis of vent hole 102 to the area where vent hole 102 is located is L1. From the perspective of the vent 102, i.e. the direction perpendicular to the panel 101, the blades of the wind wheel 303 project to the area of the vent 102, and part of the blades fall into the area enclosed by the vent 102. In any plane perpendicular to the axis of the vent hole 102, the vent hole 102 encloses an enclosed area, and the length of the blade projected on the counterbore portion 104 of the enclosed area is the longest, which is set to a value of L1. In some embodiments, the vent hole 102 of the wind guiding ring 100 is an elliptical hole, and the blade of the wind wheel 303 projects to the vent hole 102, so that the length of the blade in the long axis direction of the elliptical hole in the area of the vent hole 102 is L1. The greater the depth of the counterbore portion 104, the greater the maximum value L1 of the length of the blade of the wind wheel 303 projected to the region where the vent hole 102 is located, with the blade size being constant. A larger L1 indicates a larger area of the vent hole 102, a larger intake area of fresh air, and a larger amount of fresh air. Meanwhile, it is also shown that the longer the length of the blade of the wind wheel 303 entering the vent hole 102 is, the larger the air volume entering the wind wheel 303 becomes, and further the larger the fresh air volume becomes. The internal structure of the fresh air module 200 is limited in size, if L1 is too large, other structures of the fresh air module 200 are affected, and if L1 is too small, the increased fresh air volume is not obvious. Through continuous design and tests, the maximum value L1 of the length of the area where the blade of the wind wheel 303 projects to the vent hole 102 is 3-10 mm, so that the fresh air volume can be effectively increased, and the influence on other structures of the fresh air module 200 can be reduced.

Referring to fig. 6, in some embodiments, the minimum distance between wind wheel 303 and wind-guiding ring 100 is H1, and H1 is the distance between the lower end face of wind-guiding ring 100 and the upper end face of wind wheel 303. In order to ensure the structural safety design clearance and prevent the interference between the wind wheel 303 and the wind guide ring 100, H1 cannot be too small, and H1 is too large, which causes airflow to flow away from the clearance between the wind wheel 303 and the wind guide ring 100, and causes air loss. Through continuous design and experiments, the minimum distance H1 between the wind wheel 303 and the wind guide ring 100 is 4mm-8mm, so that the structural safety design gap can be ensured, the interference between the wind wheel 303 and the wind guide ring 100 can be prevented, and the air volume loss caused by the air flow flowing away from the gap between the wind wheel 303 and the wind guide ring 100 can be prevented.

Referring to fig. 7, fig. 7 is a relationship diagram of air volume generated at different rotation speeds in the present embodiment and the conventional embodiment, where an abscissa is a rotation speed of the wind wheel 303, and an ordinate is air volume at the air outlet 203, the vent hole 102 of the air guiding ring 100 adopted in the present embodiment is an elliptical hole, and the vent hole 102 of the air guiding ring 100 adopted in the conventional embodiment is a circular hole. As can be seen from fig. 7, the air volume generated by the present embodiment is larger than that of the conventional one at the same rotation speed.

Referring to fig. 8, in some embodiments, an air conditioner indoor unit according to an embodiment of the third aspect of the present invention includes a fresh air module 200 according to an embodiment of the second aspect of the present invention.

The air conditioner indoor unit using the fresh air module 200 of the embodiment can introduce outdoor fresh air into a room, can keep the indoor air fresh, and improves the comfort of users. Simultaneously through adopting the utility model discloses a new trend module 200 of second aspect embodiment, satisfying under the structure mounting dimension condition, effectively increasing air inlet area promotes the air input of unit interval, satisfies user's demand.
