DETAILED DESCRIPTION OF THE EMBODIMENTS

It should be understand that, all directional indications (such as "upper", "lower", "left", "right", "front", "back" ...) in the embodiments of the present disclosure are only used to explain the relative positional relationship, motion, and the like, between components in a certain posture. If the particular posture changes, the directional indication changes accordingly.
The present disclosure provides a fresh air module.
In an embodiment, as shown in FIGS. 1 to 5, the fresh air module includes:

a housing 10, having a fresh air passage 11 and a mounting port 12 communicated with the fresh air passage 11; and
a filter screen assembly 20, including a filter screen bracket 21 and a filter screen 22 mounted on the filter screen bracket 21, the filter screen assembly 20 being slidably mounted in the fresh air passage 11 through the mounting port 12.

In this embodiment, the housing 10 has a fresh air inlet and a fresh air outlet 13, where the fresh air inlet is communicated with the outdoor, and the fresh air outlet is communicated with the indoor. The fresh air passage 11 communicates the fresh air inlet and the fresh air outlet 13, so as to introduce outside air into indoor. Optionally, the fresh air outlet 13 is formed in a front side of the housing 10, so as to vent air frontwards, so that users can intuitively feel the air. In addition, the filter screen assembly 20 is mounted in the fresh air passage 11 by sliding through the mounting port 12. It can be understood that the inner wall of the fresh air passage 11 may be provided with a sliding groove, for the filter screen assembly 20 to slide, as well as for guiding and limiting the filter screen assembly 20. In an embodiment, the sliding groove is a supporting protrusion formed on the inner wall of the fresh air passage 11, so as to support the bottom of the filter screen assembly 20. Alternatively, the sliding groove is a recessed groove formed in the inner wall of the fresh air passage 11.
The filter screen 22 may be any one of an Acrylonitrile Butadiene Styrene (ABS) filter screen, a High Efficiency Particulate Air (HEPA) filter screen, an activated carbon filter screen, or a photocatalyst filter screen, or a combination thereof. The filter screen 22 is adapted to a cross section of the fresh air passage 11, which better separates the fresh air passage 11, thereby ensuring the outdoor air entering the fresh air passage 11 to be filtered through the filter screen 22. For example, the filter screen 22 is generally square.
The filter screen bracket 21 may have various forms. For example, in an embodiment, the filter screen bracket 21 is generally in a form of a frame and surrounds the outer peripheral surface of the filter screen 22. In another embodiment, the filter screen bracket 21 is in a form of a grid and supports on one surface of the filter screen 22. In still another embodiment, the filter screen bracket 21 is in a form of a hollow box, to accommodate the filter screen 22 therein.
In the embodiments, since the filter screen assembly 20 includes the filter screen bracket 21, the filter screen 22 can be mounted on the filter screen bracket 21, so as to strengthen the entire filter screen assembly 20. Therefore, even if there occur collisions between the filter screen assembly 20 and other components when drawing the filter screen assembly 20, the deformation of the filter screen 22 can be effectively reduced.
In the related art, the housing 10 is generally provided with a rotatable cover plate to cover the mounting port. After mounting the filter screen 22, the mounting port 12 can be closed by rotating the cover plate. However, the cover plate is rotatably mounted, and accordingly there exists a relatively large mounting gap between the cover plate and the edge of the mounting port 12, which easily accumulates dust. To solve this problem, in an embodiment of the present disclosure, the filter screen bracket 21 includes a cover member 212 arranged at one end of the filter screen bracket 21, configured to cover the mounting port 12. Because the filter screen assembly 20 is cooperated with the housing 10 by means of pulling and pushing, the close attachment of the cover member 212 and the housing 10 does not affect the operation of drawing the filter screen assembly 20, so that there is no need to arrange a gap between the cover member 212 and the housing 10. During assembly by pushing the filter screen assembly 20 inwardly, the cover member 212 can be closely attached to the housing 10, so as to sealingly cover the mounting port 12. In this embodiment, the cover member 212 is generally plate-shaped.
In an embodiment, referring to FIG. 9, the cover member 212 is disposed at one end of the filter screen 22. Specifically, the filter screen bracket 21 includes a frame body 211 surrounding the outer circumferential surface of the filter screen 22, and the cover member 212 constitutes a part of the frame body 211. In this embodiment, the cover member 211 being a partial structure of the frame body 211 can simplify the overall structure, and thus there is no need to additionally provide a cover member 212. In another embodiment, the cover member 212 may be an additional baffle plate provided on the frame body 211. In an embodiment, the periphery of the cover member 212 extends outward to form a ring-shaped annular flange 2121, for a better cover effect. The annular flange 2121 is disposed beyond the edge of the mounting port 12, so as to provide for a complete covering of the mounting port 12.
In an embodiment, referring to FIGS. 5 to 7, the housing 10 is provided with a protruding rib 14 that extends in the circumferential direction of the mounting port 12 and is in an annular shape. The surface of the annular flange 2121 facing the filter screen 22 abuts against the protruding rib 14. The arrangement of the protruding rib 14 can reduce the contact area between the cover member 212 and the housing 10, which ensures a better attachment of the cover member 212 and the protruding rib 14, thereby improving the sealing effect.
In an embodiment, the housing 10 is provided with a sinking groove 15. The mounting port 12 is formed in the sinking groove 15, and the cover member 212 is disposed in the sinking groove 15. At least one side of the cover member 212 is spaced apart from the groove wall of the sinking groove 15 to form a drawing gap 16, so that a user hand or a word piece can extend into the drawing gap 16 and act on the cover member 212 to draw the filter screen assembly 20. In addition, the cover member 212 is disposed in the sinking groove 15, thus the interference between the cover member 212 and an air conditioner panel can be avoided. In an embodiment, the surface of the cover member 212 away from the filter screen 22 is provided with a handle element. The handle element may be a recessed groove or a protrusion, which is convenient for users to operate.
In an embodiment, the filter screen assembly 20 and the inner wall of the fresh air passage 11 is provided with a fixing member therebetween for fixing the filter screen assembly 20 to the inner wall of the fresh air passage 11, so as to prevent the filter screen assembly 20 from loosening and falling. The fixing member may have various structures, such as a buckle connection structure or an elastic push-fitting structure.
In an embodiment, referring to FIG. 8, one of the filter screen bracket 21 and the inner wall of the fresh air passage 11 is provided with a buckle 213, and the other one is provided with a buckle groove 17 for engaging the buckle 213. For example, the buckle 213 is provided on the filter screen bracket 21, and the inner wall of the fresh air passage 11 is provided with the buckle groove 17 for engaging the buckle 213, which prevents the filter screen bracket 21 from being disengaged from the fresh air passage 11. Specifically, each of the buckles 213 is provided on each of the opposite side walls of the filter screen bracket 21, such that the filter screen bracket 21 can be more balanced, thereby improving the buckling effect.
In an embodiment, referring to FIG. 12, one of the filter screen bracket 21 and the inner wall of the fresh air passage 11 is provided with an elastic push fastener 217, and the other one is provided with a connecting member 18 for fastening with the elastic push fastener 217. When the filter screen bracket 21 is pushed inward, the elastic push fastener 217is in a compressed state and fastened with the connecting member 18; when the filter screen bracket 21 is again pushed inward by an external force, the elastic push fastener 217is further compressed, and in response to that the external force applied on the filter screen bracket 21 is removed, the elastic push fastener 217is back to an original state and detached from the connecting member 18, so as to allow the filter screen bracket 21 to detach from the housing 10. In this embodiment, the elastic push fastener 217 and the connecting member 18 are combined to form the push-fitting structure. By pushing the filter screen assembly 20, the filter screen assembly 20 is ejected under the action of the push-fitting structure, and by pushing the filter screen assembly 20 again, the filter screen assembly 20 is closely locked with the inner wall of the fresh air passage 11 under the action of the push-fitting structure. The push-fitting structure is similar to a push-fitting structure of a ballpoint pen.
In an embodiment, referring to FIGS. 9 to 11, the filter screen bracket 21 includes a frame body 211 and a limiting member 214 connected to each other, in order to prevent the filter screen 22 from falling. The frame body 211 is disposed around the outer circumference of the filter screen 22, which includes a mounting opening 216 and a fixing opening 217 arranged oppositely. The filter screen 22 is mounted in the filter screen bracket 21 through the mounting opening 216. The limiting member 214 is located in the fixing opening 217, and is abutted against the filter screen 22. During assembly, the mounting opening 216 is upward and the fixing opening 217 is downward, which corresponds to that the limiting member 214 supports the bottom surface of the filter screen 22, in order to prevent the filter screen 22 from falling. In addition, the limiting member 214 can also strengthen the entire structure, thereby reducing the deformation of the filter screen bracket 21.
Specifically, in an embodiment, the limiting member 214 includes a limiting frame 2141 extending along the circumferential direction of the filter screen bracket 21, which corresponds to that a circle of the bottom surface of the filter screen 22 is supported by the limiting member 214, thus realizing a better support effect. In another embodiment, the limiting member 214 includes a limiting rib 2142 disposed across the opposite side edges of the frame body 211. The limiting rib 2142 is generally disposed in the middle of the frame body 211, so as to support the middle of the filter screen 22. In still another embodiment, the limiting member 214 includes the limiting frame 2141 extending along the circumferential direction of the filter screen bracket 21, and the limiting rib 2142 disposed across the opposite side edges of the frame body 211.
In an embodiment, the filter screen bracket 21 is provided with a notch 215 formed on a side where the mounting opening 216 is located, in order to facilitate the removal of the filter screen 22. Specifically, the notch 215 is formed in the frame body 211, so that the filter screen 22 can be partially exposed outside the filter screen bracket 21 from the notch 215, which increases the contact area of the user with the filter screen 22, thereby facilitating the removal of the filter screen 22. Optionally, each of two notches 215 is formed on each of the opposite sides of the frame body 211, so that the opposite sides of the filter screen 22 can both be stressed for an easy removal.
In an embodiment, the mounting port 12 is disposed in the front side of the fresh air module, in order to facilitate the removal of the filter screen assembly 20. Generally, the front side is facing users and with no wall covering on, thus the mounting port 12 formed in the front side is advantageous for users to operate the filter screen assembly 20.
The present disclosure also provides an air conditioner, including a fresh air module and a heat exchange module. The specific structure of the fresh air module may refer to any of the above embodiments. It should be noted that since the air conditioner herein adopts all the technical solutions of the above embodiments, thus can achieve all the technical effects introduced by the above embodiments, which is not detailed herein. The heat exchange module includes components such as an indoor heat exchanger and a fan.
In an embodiment, the air conditioner is a wall-mounted air conditioner. The fresh air module 40 is disposed at an end of the wall-mounted air conditioner, that is, the fresh air module 40 and the heat exchange module 50 are disposed along a lateral direction.
