- Referring to
FIG. 1 andFIG. 2 , a fresh air assembly according to an embodiment of the present invention includes ahousing 1, across-flow impeller 2,evaporators 3, and anair deflector 4. Thecross-flow impeller 2, theevaporators 3, and theair deflector 4 are all disposed inside thehousing 1. Theevaporators 3 are disposed on one side of thecross-flow impeller 2 in a direction around thecross-flow impeller 2. Both ends of theair deflector 4 are connected to thehousing 1 to form afirst cavity 5. One end of theevaporators 3 is connected to thehousing 1 and the other end thereof is connected to theair deflector 4 to form asecond cavity 6, thesecond cavity 6 communicates with thefirst cavity 5, theevaporators 3 are enclosed with theair deflector 4 to form awind chamber 7, and thecross-flow impeller 2 is disposed inside thewind chamber 7. Thehousing 1 is provided with anair outlet 17 and anair inlet 16, theair outlet 17 communicates with thewind chamber 7, and theair inlet 16 communicates with thefirst cavity 5. In this embodiment, thesecond cavity 6 communicates with thewind chamber 7 through theevaporators 3, and fresh air can flow into thewind chamber 7 through theevaporators 3. - The working principle of the above-mentioned fresh air assembly is as follows: The
cross-flow impeller 2 rotates to form a negative pressure between thewind chamber 7 and thesecond cavity 6, so that theevaporators 3 draw the air in thesecond cavity 6 into thewind chamber 7. Then, the air in thefirst cavity 5 flows into thesecond cavity 6 to supplement the air volume in thesecond cavity 6. Finally, fresh air flows into thefirst cavity 5 from theair inlet 16 to supplement the air volume in thefirst cavity 5. In this way, an air flow passage is formed. Afterwards, fresh air enters thefirst cavity 5 from theair inlet 16, flows into thesecond cavity 6 from thefirst cavity 5, is drawn into thewind chamber 7 by theevaporators 3, and is blown into a room from theair outlet 17 under the action of thecross-flow impeller 2. When the fresh air is drawn into thewind chamber 7 by theevaporators 3, theevaporators 3 dehumidify, cool, or heat the fresh air, and therefore functions of theevaporators 3 are fully utilized. - According to the fresh air assembly above, a dehumidifier module is removed, and fresh air that is to enter an air-conditioned room is processed by using the
evaporators 3, thereby improving utilization of theevaporators 3. In addition, theevaporators 3 are disposed around thecross-flow impeller 2, and this increases the space on the air intake side of theevaporators 3, ensures the intake volume and flow rate of the fresh air, and effectively ensures the volume of fresh air entering the room. Moreover, because the dehumidifier module is removed, noise is reduced, overall energy consumption and costs are decreased, and cleaning and maintenance are more convenient. - Referring to
FIG. 1 toFIG. 6 , in another embodiment, there are at least twoevaporators 3, and theevaporators 3 are sequentially connected and are disposed in the direction around thecross-flow impeller 2. Preferably, there are twoevaporators 3, and the twoevaporators 3 are connected to each other to form a V shape. Certainly, there may alternatively be threeevaporators 3, and the threeevaporators 3 are sequentially connected. There may alternatively be fourevaporators 3, and the fourevaporators 3 are sequentially connected in a C-shaped arrangement, and so on. Connecting a plurality ofevaporators 3 together increases not only the area of theevaporators 3 but also the space between theevaporators 3 and thehousing 1 and the fresh air volume on the side of theevaporators 3 that faces away from thecross-flow impeller 2. As such, when a negative pressure is formed on both sides of theevaporators 3 under the action of thecross-flow impeller 2, a volume of fresh air drawn into thewind chamber 7 by theevaporators 3 from thesecond cavity 6 increases. This ensures that a sufficient volume of fresh air flows into the room, and the air-conditioning effect in the room is maintained. - In another embodiment, the
evaporators 3 are arc-shaped or semicircular, and the arc-shaped orsemicircular evaporators 3 are disposed on one side of thecross-flow impeller 2 in the direction around thecross-flow impeller 2. Disposing the arc-shaped orsemicircular evaporators 3 to manufacture theevaporators 3 at a time omits an assembly procedure required for usingmultiple evaporators 3, making the assembly more convenient. - Referring to
FIG. 4 , in another embodiment, theair deflector 4 is provided with air-guidingholes 4231, and thefirst cavity 5 communicates with thesecond cavity 6 through the air-guidingholes 4231. Directly disposing the air-guidingholes 4231 facilitates flowing of the fresh air from thesecond cavity 6 to thefirst cavity 5. In this embodiment, the air-guidingholes 4231 may be rectangular, circular, triangular, pentagonal, hexagonal, or the like. - In another embodiment, there are at least two air-guiding
holes 4231, and the at least two air-guidingholes 4231 are spaced on theair deflector 4. Disposing a plurality of air-guidingholes 4231 can increase the volume of fresh air flowing into thesecond cavity 6, thereby ensuring a sufficient volume of fresh air in thesecond cavity 6. In this way, theevaporators 3 can continuously draw the fresh air from thesecond cavity 6 into thewind chamber 7 and blow the fresh air from thewind chamber 7 into the room. Moreover, the plurality of air-guidingholes 4231 are spaced on theair deflector 4, and this can ensure sufficient strength of theair deflector 4, so as to prevent the structural strength of theair deflector 4 from being reduced because only one air-guidinghole 4231 with a large diameter is disposed to ensure the fresh air volume. - Referring to
FIG. 1 andFIG. 6 , in another embodiment, thehousing 1 includes abottom plate 11, atop plate 12, anouter side plate 13, and anintermediate separator plate 14. One end of theouter side plate 13 and one end of theintermediate separator plate 14 are respectively connected to opposite ends of thebottom plate 11. Thetop plate 12 is disposed at the other end of theintermediate separator plate 14, and is spaced from the other end of theouter side plate 13 to form theair outlet 17. Preferably, thebottom plate 11 further includes twoend plates 15. The twoend plates 15 are respectively connected to the two ends of theouter side plate 13, the two ends of theintermediate separator plate 14, the two ends of thebottom plate 11, and two ends of thetop plate 12 to form an internal space accommodating theair deflector 4, theevaporators 3, and thecross-flow impeller 2. In this embodiment, theair inlet 16 is disposed on theintermediate separator plate 14. - Referring to
FIG. 1 toFIG. 6 , theair deflector 4 includes anarc segment 41 and abending segment 42. Thearc segment 41 is disposed on an outer side of thecross-flow impeller 2 in the direction around thecross-flow impeller 2, and one end of thearc segment 41 is connected to thetop plate 12 and the other end thereof is connected to the bendingsegment 42. The bendingsegment 42 is fixedly connected to thebottom plate 11. Preferably, theevaporators 3 are fixedly connected to the bendingsegment 42. In this embodiment, thearc segment 41 can play a flow guiding function, so that the fresh air is blown from theair outlet 17 into the room along thearc segment 41 under the action of thecross-flow impeller 2. The bendingsegment 42 is fixedly connected to thebottom plate 11 to support the arc segment. - Referring to
FIG. 1 toFIG. 6 , the bendingsegment 42 includes a connectingportion 421, aninclined portion 422, avertical portion 423, and aflat portion 424. One end of the connectingportion 421 is connected to thearc segment 41, and the other end thereof is connected to theinclined portion 422. One end of thevertical portion 423 is connected to theinclined portion 422, the other end thereof is connected to theflat portion 424, and an included angle between theinclined portion 422 and thevertical portion 423 is an obtuse angle.

In this embodiment, theinclined portion 422 is inclined towards a side that faces away from theevaporators 3, so that the space of thewind chamber 7 can be increased, and the space of thefirst cavity 5 can be reduced at the same time. This is conducive for fresh air to enter thefirst cavity 5 from theair inlet 16 and rapidly flow into thesecond cavity 6. - Referring to
FIG. 1 toFIG. 6 , abaffle plate 8 is provided between the bendingsegment 42 and theintermediate separator plate 14. Thebaffle plate 8 divides thefirst cavity 5 into anupper cavity 51 and alower cavity 52. Thelower cavity 52 communicates with theair inlet 16 and thesecond cavity 6. Disposing thebaffle plate 8 can divide thefirst cavity 5 into theupper cavity 51 and thelower cavity 52. Theupper cavity 51 and thelower cavity 52 are sealed relative to each other, so as to prevent fresh air from entering theupper cavity 51. After entering thelower cavity 52 from theair inlet 16, fresh air directly flows into thesecond cavity 6 through the air-guidingholes 4231. The fresh air flows more stably, and this prevents the fresh air from flowing between theupper cavity 51 and thelower cavity 52 and affecting the volume of fresh air flowing into thesecond cavity 6. - In another embodiment, the
air inlet 16 is provided with a filter screen. Disposing the filter screen can prevent dust in the air from entering into the fresh air assembly, and prevent the dust from covering theevaporators 3 and thecross-flow impeller 2 and affecting the service life of theevaporators 3 and thecross-flow impeller 2. - Referring to
FIG. 7 , in another embodiment, theair inlet 16 is provided with adamper 9 on a side facing away from thefirst cavity 5. Thedisposed damper 9 can close theair inlet 16 when thecross-flow impeller 2 stops working.

FIG. 7 , the fresh air assembly further includes an opening apparatus. Thedamper 9 is rotatably disposed on one side of theair inlet 16 through a rotating shaft. The opening apparatus is capable of driving thedamper 9 to rotate, so that thedamper 9 covers theair inlet 16 up or moves away from theair inlet 16. Disposing the opening apparatus facilitates opening and closing of thedamper 9. - Referring to
FIG. 7 toFIG. 9 , the opening apparatus includes amanual switch 101 and a connectingrod 102. One end of the connectingrod 102 is connected to thedamper 9 and the other end thereof is connected to themanual switch 101. Themanual switch 101 is capable of driving the connectingrod 102 to move, so as to control thedamper 9 to cover theair inlet 16 up or move away from theair inlet 16. Specifically, themanual switch 101 is disposed on oneend plate 15. The connectingrod 102 is L-shaped. Thedamper 9 is provided with a connectingplate 91. One end of the connectingrod 102 is rotationally connected to the connectingplate 91.

The shiftingblock 1012 is fixedly connected to the connectingrod 102. Pulling theshifting block 1012 moves theshifting block 1012 along the chute. Then, the shiftingblock 1012 drives the connectingrod 102 to move. The movement of the connectingrod 102 drives thedamper 9 to rotate, so that thedamper 9 covers theair inlet 16 up or moves away from theair inlet 16. Arubber sleeve 105 is sleeved on the connectingrod 102 between theguide hole 1041 and theshifting block 1012 in order to avoid excessive abrasion at the joint between the connectingrod 102, and theintermediate separator plate 14 and theend plate 15. In a specific embodiment, when thedamper 9 needs to be opened to allow fresh air to flow into theair inlet 16, the shiftingblock 1012 is toggled so that theshifting block 1012 moves along the chute towards a side close to theintermediate separator plate 14, and theshifting block 1012 pushes the connectingrod 102 to move along theguide hole 1041. Then, one end of the connectingrod 102 pushes the connectingplate 91 to drive thedamper 9 to rotate, so that thedamper 9 moves away from theair inlet 16 and fresh air can flow from theair inlet 16 into thefirst cavity 5.
