It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes are not set forth in detail in order to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

The main body of this embodiment is an air conditioner, which includes an indoor unit and an outdoor unit, wherein the indoor unit includes a fresh air module 1000 for introducing fresh air in an outdoor environment into an indoor environment.

Referring to fig. 1 and fig. 2, a schematic structural diagram and a schematic cross-sectional diagram of a fresh air module 1000 provided in this embodiment are shown, and it can be seen that, in this embodiment, the fresh air module 1000 specifically includes:

the air conditioner comprises a shell 1100, wherein an air inlet 1110 is formed in the shell 1100, and the air inlet 1110 is used for introducing fresh air in an outdoor environment into an indoor environment;

and a filter 1200, wherein the filter 1200 is disposed in the casing 1100 to filter fresh air entering from the air inlet 1110. Wherein, it is cuboid shape to filter piece 1200, and it has the first filtration region 1210 that staggers each other with air intake 1110 to filter piece 1200 to just be right to air intake 1110 and with the second filtration region 1220 that first filtration region 1210 links to each other, first filtration region 1210 and second filtration region 1220 arrange in proper order along the length direction who filters piece 1200.

The housing 1100 is a shell-shaped component for accommodating the structure and defining the air inlets 1110 and the like, and in this embodiment, the air inlets 1110 are communicated with the air outlet of the fresh air pipe in the fresh air module 1000, so as to introduce the fresh air in the outdoor environment to the filter element 1200. The filter 1200 is a component capable of filtering an air flow, and the first filtering area 1210 and the second filtering area 1220 are corresponding to local areas on the filter 1200, through which the air flow can pass and filter the air flow, in this embodiment, the filter 1200 is specifically a HEPA filter. Of course, the specific form of the filter element 1200 may be selected by the practitioner depending on the particular application without affecting the objectives of the invention. For example, in another embodiment, the filter element 1200 is embodied as an activated carbon filter.

Here, since the first filtering area 1210 and the air inlet 1110 are staggered from each other, the fresh air entering the casing 1100 from the air inlet 1110 mainly blows towards the second filtering area 1220, and the fresh air received by the first filtering area 1210 is significantly smaller than the fresh air received by the second filtering area 1220, which results in a smaller effective use area and a lower use efficiency of the filter 1200; in addition, because the fresh air is blown to the local area of the filter element 1200 in a concentrated manner, the actual flow area of the fresh air is small, and the filter element 1200 has high pneumatic resistance, which affects the fresh air volume. Therefore, at this moment, the diversion cone 1300 needs to be arranged so that the fresh air is uniformly diffused to the filter element 1200, and the diffusion range of the fresh air in the direction close to the first filter area 1210 is enlarged, so that the purposes of increasing the effective use area and the use efficiency of the filter element 1200 and reducing the wind resistance are achieved.

Correspondingly, in this embodiment, the fresh air module 1000 further includes:

the splitter cone 1300, the splitter cone 1300 is disposed between the filter element 1200 and the housing 1100, and a flow-facing surface is formed on an outer surface of one side of the splitter cone 1300, for guiding the fresh air at the air inlet 1110, please refer to fig. 3, a dashed line with an arrow in fig. 3 is used for representing a flow path of the air flow, and it can be seen that the splitter cone 1300 specifically includes:

a first guide 1310 having a first guide surface 1311 partially constituting an incident surface;

the second flow guiding part 1320 is in a conical shape, the outer conical surface of the second flow guiding part is a second flow guiding surface 1321, and the second flow guiding surface 1321 partially forms a flow facing surface;

referring to fig. 4, a dotted line with an arrow in fig. 4 is used to represent a flow path of the airflow, the dotted line is used to represent an axis of the second guiding portion 1320, the first guiding surface 1311 is connected to a smaller end of the second guiding surface 1321, the first guiding surface 1311 extends from the smaller end of the second guiding surface 1321 in a direction away from the axis of the second guiding portion 1320, and the first guiding surface 1311 is inclined toward a side close to the larger end of the second guiding surface 1321; a first included angle α is formed between the first guiding surface 1311 and the axis of the second guiding portion 1320, a second included angle β is formed between the second guiding surface 1321 and the axis of the second guiding portion 1320, and the first included angle α is greater than the second included angle β.

Here, as shown in fig. 1 and 2, in the present embodiment, the incident flow surface faces the air inlet 1110, and in the direction from the first filter area 1210 to the second filter area 1220, the first guide 1310 and the second guide 1320 are arranged in sequence, and the axis of the second guide 1320 and the axis of the air inlet 1110 coincide with each other.

The fresh air entering from the air inlet 1110 first contacts with the smaller end of the second flow guiding surface 1321, and is divided by the smaller end of the second flow guiding surface 1321. Here, since the smaller ends of the first flow guiding surface 1311 and the second flow guiding surface 1321 are connected, the fresh air is substantially split into two air flows after contacting the smaller end of the second flow guiding surface 1321. One air stream, which may be defined as a first fresh air stream, flows along the first flow guide surface 1311, and the other air stream, which may be defined as a second fresh air stream, flows along the second flow guide surface 1321.

The first fresh air flows along the first guiding surface 1311, so that the included angle formed by the flow direction of the first fresh air and the axis of the second guiding portion 1320 is the same as the first included angle α described above, and for the second fresh air, the included angle formed by the flow direction of the second fresh air and the axis of the second guiding portion 1320 is the same as the second included angle β described above.

Since the first included angle α is greater than the second included angle β, the first fresh air guided by the first guide surface 1311 can be spread farther in a direction away from the axis of the second guide 1320. Therefore, as shown in fig. 2, more parts of the first filtering area 1210 are exposed to the fresh air, and the effective use area of the first filtering area 1210 is increased. Meanwhile, the second fresh air is also uniformly diffused by the second flow guide surface 1321, and finally reaches the second filtering area 1220, and is filtered by the second filtering area 1220.

The present embodiment provides the tap 1300, and the tap 1300 enables the air flow to be uniformly diffused to the filter member 1200 by means of the first and second

flow guide portions

1310 and 1320, thereby reducing the aerodynamic resistance of the filter member 1200. Meanwhile, due to the existence of the first flow guiding surface 1311 as described above, the flow splitter cone 1300 can also expand the diffusion range of the airflow in the direction close to the first filtering area 1210, so as to improve the effective use area and the use efficiency of the whole filtering element 1200, reduce the aerodynamic resistance of the filtering element 1200, and prolong the service life of the filtering element 1200.

It should be noted that, in the present embodiment, the above-mentioned splitter cone 1300 is mainly used to solve the problems that the filter element 1200 has a local area not directly opposite to the tuyere, the effective usage area of the filter element 1200 is small, the usage efficiency is low, and the aerodynamic resistance is high. However, this does not represent a limitation on the application scenario of the diverging cone 1300, and the diverging cone 1300 described above can be used in any situation where it is necessary to expand the diffusion range of the airflow in a certain direction, and this is not particularly limited in this application.

The specific structure of the skimmer cone 1300 will be further described below.

Referring to fig. 3, the first flow guiding surface 1311 of the diverging cone 1300 may be a plane, a conical surface, or the like, and in this embodiment, the first flow guiding surface 1311 is a plane. Compared with the first flow guide surface 1311, the conical surface is adopted, and the first flow guide surface 1311 is configured as a plane, so that the airflow on the first flow guide surface 1311 mainly moves towards the side close to the first filter area 1210, rather than flows towards the side of the first flow guide surface 1311.

The second flow guiding surface 1321 is mainly used to uniformly diffuse the airflow to the second filtering region 1220, so that the fresh air cannot be directly blown to the second filtering region 1220 opposite to the fresh air, the blocking effect of the filter element 1200 on the airflow is reduced, and the fresh air volume is further increased. The inclination of the second flow guiding surface 1321 may be configured to be 30 ° to 40 °, and within this range, the flow guiding effect of the second flow guiding surface 1321 can be ensured, and the aerodynamic resistance of the incident flow area of the second flow guiding part 1320 can be reduced.

Referring to fig. 4, the distance between the distal edge of the first flow-guiding surface 1311 and the second flow-guiding surface 1321, compared to the axis of the second flow-guiding part 1320, and the axis of the second flow-guiding part 1320 may be set to be the same, but such setting may make the first flow-guiding surface 1311 extend for a shorter length, so that the flow path and the guiding time of the airflow guided by the first flow-guiding surface 1311 on the first flow-guiding surface 1311 are shorter, and the airflow may not act on the first filtering area 1210 well. Therefore, in order to further improve the guiding effect of the first guiding surface 1311 on the airflow, in the embodiment, the vertical distance between the far end edge of the first guiding surface 1311, compared to the axis of the second guiding portion 1320, and the axis of the second guiding portion 1320 is the first distance D1, the vertical distance between the far end edge of the second guiding surface 1321, compared to the axis of the second guiding portion 1320, and the axis of the second guiding portion 1320 is the second distance D2, and the first distance D1 is greater than the second distance D2.

The first distance D1 is configured to be larger than the second distance D2, so that the flow path and the guiding time of the airflow guided by the first guiding surface 1311 on the first guiding surface 1311 can be prolonged, and the guiding effect of the first guiding surface 1311 can be improved.

Further, the first and

second guiding portions

1310 and 1320 may be separately disposed, but this may affect the aerodynamic effect of the tap 1300. Correspondingly, referring to fig. 3, in the present embodiment, an opening 1320a is formed at a side portion of the second flow guiding portion 1320, and the first flow guiding portion 1310 is combined at the opening 1320a to form an integral structure with the second flow guiding portion 1320. The second guide portion 1320 has a cone shape with an opening 1320a formed at a side thereof, and the first guide portion 1310 is combined at the opening 1320a to partially or completely occupy the opening 1320a, so as to form an integrated structure with the second guide portion 1320, thereby improving the aerodynamic effect of the tap cone 1300 and reducing the aerodynamic resistance of the tap cone 1300.

In addition, in this embodiment, the diversion cone 1300 further includes two transition connection portions 1330, the two transition connection portions 1330 are combined in the opening 1320a and respectively disposed between the side portions of the first diversion portion 1310 and the second diversion portion 1320 facing each other for enabling the first diversion portion 1310 and the second diversion portion 1320 to be in smooth transition connection, so that the diversion cone 1300 is generally in a regular shape as a whole, the transition connection portion 1330 has a transition diversion surface 1331 partially forming a head-on surface, in this embodiment, the transition diversion surface 1331 is specifically a plane; the transition guide surface 1331 and the first guide surface 1311 form an included angle, and the two are in smooth transition connection; the transition guiding surface 1331 extends along a tangential direction of a circle of the cross section of the second guiding surface 1321 and is connected to the second guiding surface 1321.

In addition, referring to fig. 3 and 4, in the present embodiment, the first flow guiding portion 1310, the second flow guiding portion 1320, and the transition connecting portion 1330 are all plate structures, so that the diversion cone 1300 is overall bucket-shaped, and an implementer may also set the diversion cone 1300 to be overall solid block-shaped, which is not limited in this application.

When the above-mentioned diverging cone 1300 is applied to the fresh air module 1000 described in the foregoing, since the diverging cone 1300 partially covers the second filtering region 1220, the effective usage area of the second filtering region 1220 is reduced. Correspondingly, in the present embodiment, the through holes 1340 are densely arranged on the flow-facing surface of the diverter cone 1300, so that part of the airflow can directly pass through the diverter cone 1300 and blow toward the filter element 1200, thereby increasing the usage area of the filter element 1200. It is noted that the aperture ratio of the through holes 1340 can be set to 60% to 70%, and the aperture can be selected to be 3mm to 8mm, for example, 6mm as shown in the embodiment, so that the splitter cone 1300 can direct the airflow to the desired position and simultaneously allow a suitable amount of airflow to directly pass through and blow toward the second filtering area 1220.

In addition, as illustrated in fig. 2, the vertical distance from the splitter cone 1300 to the filter element 1200 may be set to be greater than 10mm, and a suitable diffusion range of the air flow can be ensured below this value. The shape of the above-mentioned splitter cone 1300 may also be correspondingly configured by the practitioner according to the shape of the air inlet 1110, for example, the second flow guiding surface 1321 has different shapes of an inclined top, a circumferential contour, and the like, which is not particularly limited in this application.
