- Referring to
FIG. 1 to FIG. 13 , the present application provides embodiments of a fresh air module and an air conditioner including the fresh air module. The dashed arrows inFIG. 5 andFIG. 9 indicate an airflow direction. The fresh air module can improve the efficiency of air purification by the fresh air module. The air conditioner may be an indoor unit of a wall-mounted air conditioner, an indoor unit of a cabinet air conditioner, an air machine, an indoor unit of a ceiling type air conditioner or a mobile air conditioner. In the following embodiments, the indoor unit of the wall-mounted air conditioner is taken as an example for illustration, and provides reference for other types of air conditioner. - Referring to
FIG. 2 ,FIG. 3 andFIG. 9 , in an embodiment of thefresh air module 200, thefresh air module 200 includes ahousing 300, afan assembly 400 and apurification assembly 500. Thehousing 300 is provided with afresh air inlet 301 and afresh air outlet 302, and thehousing 300 is provided with afresh air duct 330 inside. Thefresh air duct 330 communicates with thefresh air inlet 301 and thefresh air outlet 302. Thefan assembly 400 and thepurification assembly 500 are mounted in thefresh air duct 330, and thepurification assembly 500 is located at an end of thefan assembly 400 along an axial direction of thefan assembly 400 and corresponds to an air inlet end of thefan assembly 400. - In an embodiment, the
fresh air inlet 301 may be provided at a bottom of thehousing 300, and thefresh air outlet 302 may be provided at a top, a front side, a left side or a right side of thehousing 300, and the positions of thefresh air inlet 301 and thefresh air outlet 302 can be designed according to the types of the air conditioners employing the fresh air module in practical applications. In this embodiment, thefresh air inlet 301 can be provided at the bottom of thehousing 300, and thefresh air outlet 302 can be provided at a front side of thehousing 300. Thefresh air inlet 301 and thefresh air outlet 302 are distributed in different radial directions of thefan assembly 400. - Referring to
FIG. 5 , when thefresh air module 200 works, thefan assembly 400 is turned on, and thefan assembly 400 drives fresh air to enter thefresh air duct 330 from thefresh air inlet 301. The fresh air flows to the air inlet end of thefan assembly 400 firstly, and is subsequently purified to be clean fresh air by thepurification assembly 500 which is located at the air inlet end of thefan assembly 400. The clean fresh air enters the fan assembly from the air inlet end of thefan assembly 400 and is propelled by thefan assembly 400 along the radial directions to thefresh air outlet 302. Finally, the clean fresh air is blown out from thefresh air outlet 302. - The air enters the
fan assembly 400 along the axial direction of thefan assembly 400 and exits thefan assembly 400 along the radial directions of thefan assembly 400. As compared to a narrower air inlet surface formed at thefresh air inlet 301 and the vicinity, a larger air inlet surface is formed at the air inlet end of thefan assembly 400, and thus a relatively large air inlet space is formed at the air inlet end of the fan assembly. Therefore, thepurification assembly 500 is arranged to correspond to the air inlet end of thefan assembly 400, accordingly a purification surface of thepurification assembly 500, which is provided for the air to pass through and be purified, can be set to be larger, and the efficiency of thepurification assembly 500 to purify the air is improved. In addition, since thepurification assembly 500 is correspondingly set to be relatively large, the amount of air that can be purified by thepurification assembly 500 is accordingly increased, the service life of thepurification assembly 500 is accordingly prolonged and it takes a longer period before anew purification assembly 500 is needed. - There are various schemes for the
purification assembly 500, and the schemes are not limited herein. For example, the schemes include but are not limited to that thepurification assembly 500 includes a mountingframe 510 and a purifyingmember 520 mounted on the mounting frame 510 (as shown inFIG. 13 ). The purifyingmember 520 may be adapted to remove any one or more types of air pollutant such as dust, fine particulate matter, microorganisms, and organic volatile gases such as formaldehyde in the air. The specific type of the purifyingmember 520 may be selected according to the function thereof, and the purifyingmember 520 may be any one or two of a conventional filter screen, an HEPA screen, a formaldehyde remover or an IFD filter, or be any one or more than one of a primary efficiency filter screen, a medium efficiency filter screen, and a high efficiency filter screen. - According to this embodiment of the present application, the
purification assembly 500 is disposed at one end of thefan assembly 400 along the axial direction of thefan assembly 400 and corresponds to the air inlet end of thefan assembly 400, the large air inlet space at the air inlet end of thefan assembly 400 can be utilized, so that the purification surface of thepurification assembly 500, which is provided for the air to pass through and be purified, can be set to be larger, which improves the air purification efficiency of thepurification assembly 500. In addition, since thepurification assembly 500 is correspondingly designed to be relatively large, thepurification assembly 500 can capture more air pollutants, the service life of thepurification assembly 500 is accordingly prolonged and it takes a longer period before anew purification assembly 500 is needed. - Referring to
FIG. 3 ,FIG. 5 andFIG. 9 , in an embodiment, thefresh air module 200 further includes amiddle partition plate 600 disposed in thefresh air duct 330 and located at the air inlet end of thefan assembly 400. Themiddle partition plate 600 is provided with aventilation hole 610 corresponding to the air inlet end of thefan assembly 400. Thepurification assembly 500 is mounted on themiddle partition plate 600 and located on an air inlet side of theventilation hole 610. - Referring to
FIG. 2 andFIG. 10 , in an embodiment, in order to facilitate disassembly and assembly of thepurification assembly 500, thefresh air outlet 302 is provided on a front side wall of thehousing 300, and a mountingopening 303 is provided on a side of thefresh air outlet 302. Thepurification assembly 500 is mounted on themiddle partition plate 600 and movable from the mounting opening (303) in a pull-push manner. - In an embodiment, the mounting
opening 303 is in an elongated strip shape and extended in the same direction as one side of thefresh air outlet 302. By mounting thepurification assembly 500 to themiddle partition plate 600 in a pull-push manner from the mountingopening 303, thepurification assembly 500 has a working state after being mounted on the middle partition plate and corresponding to theventilation hole 610 of themiddle partition plate 600, and an idle state after being pulled out from themiddle partition plate 600 through the mountingopening 303. In the working state, thepurification assembly 500 can purify the airflow flowing into theair outlet cavity 332 from theair inlet cavity 331 through theventilation hole 610 to remove pollutants in the air. In the idle state, thepurification assembly 500 can be cleaned or replaced by the user. The user can switch the state of thepurification assembly 500 by pulling thepurification assembly 500 by hands, which is simple and easy to operate. - In addition, the
fresh air outlet 302 of thefresh air module 200 usually faces an area where the user is located, and the mountingopening 303 for pulling or pushing thepurification assembly 500 is disposed at a side of thefresh air outlet 302, that is, the mountingopening 303 faces the area where the user is located, so that it is convenient for the user to draw thepurification assembly 500 from the front side to switch the states of thepurification assembly 500. - Referring to
FIG. 10 to FIG. 12 , in an embodiment, in order to facilitate the pulling and pushing of thepurification assembly 500 on themiddle partition plate 600, themiddle partition plate 600 is configured with aguide groove 620 at a periphery of the air inlet side of theventilation hole 610. Theguide groove 620 has an opening towards the mountingopening 303 of thehousing 300, and theguide groove 620 is adapted to guide the pulling, pushing and mounting of thepurification assembly 500. The opening of theguide groove 620 is docked with the mountingopening 303, so that after thepurification assembly 500 is pushed inward from the mountingopening 303, thepurification assembly 500 will move along theguide groove 620 toward theventilation hole 610 on themiddle partition plate 600. When thepurification assembly 500 reaches an inner end of theguide groove 620, thepurification assembly 500 covers theventilation hole 610. - In this regard, when the
purification assembly 500 is in the working state, and a gap is formed between theguide groove 620 and thepurification assembly 500, a portion of the airflow entering from thefresh air inlet 301 may leak from the gap to theventilation hole 610, and then enters thefan assembly 400 through theventilation hole 610 without passing through thepurification assembly 500. To avoid this from occurring, optionally, a shape of theguide groove 620 can be adapted to match a shape of thepurification assembly 500, and an inner wall surface of theguide groove 620 contacts an outer peripheral wall of thepurification assembly 500 to seal the gap between the inner wall surface and the outer peripheral wall. - In an embodiment, when the
purification assembly 500 is in the working state, the inner wall surface of theguide groove 620 and the outer peripheral wall of thepurification assembly 500 are in close contact to abut against each other, so that the gap between theguide groove 620 and thepurification assembly 500 is close to be none or minimal, thereby achieving the effect of sealing the gap between the two. As to the shape of theguide groove 620, the shape of theguide groove 620 should be consistent with the shape of thepurification assembly 500. Therefore, the shape of theguide groove 620 can be designed according to the shape of thepurification assembly 500. The shape of thepurification assembly 500 may be, but is not limited to shapes of semi-circular, or semi-elliptical, or a shape liking a semi-racetrack. - Referring to
FIG. 10 to FIG. 12 , in an embodiment, thepurification assembly 500 is in a semi-racetrack shape. Accordingly, theguide groove 620 is also in a semi-racetrack shape. In an embodiment, theguide groove 620 has an arc-shapedguiding wall 621 that is arc-shaped and surrounds a side of theventilation hole 610 away from the mountingopening 303, and strip-shaped guidingwalls 622 extending from two ends of the arc-shapedguiding wall 621 along a straight line towards the mountingopening 303. The two strip-shaped guidingwalls 622 and the arc-shapedguiding wall 621 cooperate to form a semi-racetrack shape. - In an embodiment, a height of each strip-shaped
guide wall 622 from a surface of themiddle partition plate 600 is greater than a height of the arc-shapedguide wall 621 from the surface of themiddle partition plate 600, so that an inner wall surface of each strip-shapedguide wall 622 forms a large guide surface, which helps to guide thepurification assembly 500 to enter or move from the opening of theguide groove 620, and prevents thepurification assembly 500 from deviating from the opening of theguide groove 620 and being separated from theguide groove 620. - In order to ensure the stability of the
purification assembly 500 in the working state,elastic buckles 540 may be provided on two opposite sides of thepurification assembly 500. The two strip-shapedguide walls 622 of theguide groove 620 are recessed to form positioninggrooves 623 corresponding to theelastic buckles 540, and thepositioning grooves 623 are adapted for clamping theelastic buckles 540 and positioning thepurification assembly 500 in theguide groove 620. - When the
purification assembly 500 is being installed, thepurification assembly 500 is pushed inwards along theguide groove 620 from the mountingopening 303. When thepurification assembly 500 is in the working state, theelastic buckles 540 on thepurification assembly 500 are clamped by thepositioning grooves 623 on the strip-shapedguide walls 622 of theguide groove 620, so that thepurification assembly 500 is fixed and not prone to being loosen and falling off. When thepurification assembly 500 needs to be disassembled, thepurification assembly 500 is forced by an external force to overcome the binding force of theelastic buckles 540, and elastically deformed to separate from thepositioning grooves 623. Subsequently, thepurification assembly 500 can be pulled out, and switched to the idle state. - Referring to
FIG. 10 ,FIG. 12 andFIG. 13 , on the basis of any one of the above embodiments, because that thepurification assembly 500 includes a mountingframe 510 and a purifyingmember 520 mounted on the mountingframe 510, in an embodiment, the mountingframe 510 includes amain frame 511 and aside frame 512 arranged at one end of themain frame 511. Themain frame 511 is formed with a mounting groove with an opening facing a frontair inlet cavity 3312, and the mounting groove is configured to mount the purifyingmember 520. Theside frame 512 is adapted for being held by the user to pull or push the mountingframe 510, thereby implementing pulling and mounting of thewhole purification assembly 500. - Further, the
side frame 512 of the mountingframe 510 has anend plate 513 away from themain frame 511 of the mountingframe 510. Theend plate 513 can be adapted to cover the mountingopening 303. Theend plate 513 is formed with ahandle 530 for the user to hold. As theend plate 513 can fit and cover the mountingopening 303, the overall appearance of thefresh air module 200 can be smooth, and external sundries can be prevented from falling into thefresh air module 200 through the mountingopening 303 to cause contamination in thefresh air module 200. - Referring to
FIG. 5 ,FIG. 7 and FIG. 8 , as for the shape of thehandle 530, thehandle 530 may be a pull ring, a handle slot, or a handle hole. However, in this regard, thehandle 530 of these shapes may be concave or convex relative to other outer surfaces of thefresh air module 200, thereby compromising the integrity of the overall exterior surface of thefresh air module 200. - In view of this, in order to improve the integrity of the overall outer surface of the
fresh air module 200, an outer surface of thehandle 530 can be flush with an outer surface of theend plate 513, and thehandle 530 is adapted to that, when a portion thereof is pressed inwardly, another portion thereof is rotated outwards for being held by the user (as shown by the dashed arrow inFIG. 8 ). In an embodiment, thehandle 530 includes a pressing portion 531 and a handheld portion 532 connected to the pressing portion 531, and a portion of thehandle 530 located between the pressing portion 531 and the handheld portion 532 is rotatably connected to theend plate 513. P inFIG. 7 and FIG. 8 indicates a position where thehandle 530 is rotatably mounted. - Therefore, when the pressing portion 531 of the
handle 530 is pressed inwardly, thehandle 530 rotates relative to theend plate 513. Thus, the handheld portion 532 of thehandle 530 rotates outwards, and can be subsequently held by the user to pull out the mountingframe 510. For the convenience of the user to pull and push, an inner wall surface of the handheld portion 532 may be formed with a pull ring for the user to hold and pull, and the pull ring is hidden in theend plate 513 and not exposed to the outside when not being used, which does not compromise the integrity of the overall outer surface of thefresh air module 200. - Referring to
FIG. 4 ,FIG. 5 andFIG. 9 , based on any one of the above embodiments, themiddle partition plate 600 divides thefresh air duct 330 into anair inlet cavity 331 in communication with thefresh air inlet 301 and anair outlet cavity 332 in communication with thefresh air outlet 302. Theair outlet cavity 332 communicates with theair inlet cavity 331 through theventilation hole 610 of themiddle partition plate 600. Thefan assembly 400 is located in theair outlet cavity 332. - Referring to
