[0035] Please refer to Figures 1 to 8 , the present invention provides an embodiment of a fresh air module and an air conditioner including the fresh air module; wherein, Figure 4 and Figure 5 the dotted arrows in Figure 8 represent the air flow direction;

[0036] Please refer to Figure 2 , Figure 7 and Figure 8 , in an embodiment of the fresh air module 200, the fresh air module 200 includes a housing 300 and a middle partition 600; the housing 300 includes a bottom shell 310 and a shell cover 320 that cooperates with the bottom shell 310 to form a fresh air duct 330. The fresh air duct 330 includes an air inlet cavity 331 and an air outlet cavity 332; the middle partition 600 is disposed between the air inlet cavity 331 and the air outlet cavity 332, and the middle partition 600 is provided with ventilation holes 610 that communicate the air outlet cavity 332 with the air inlet cavity 331. Among them, the middle partition 600 is configured with a first pre-positioning member 10, and the bottom shell 310 is configured with a first mating member 30. The first mating member 30 is adapted to be connected to the first pre-positioning member 10 to position the middle partition 600 on the bottom shell 310; then the bottom shell 310, the middle partition 600, and the shell cover 320 are fixedly connected through a connecting member passing through.

[0037] Specifically, the housing 300 of the fresh air module 200 may be provided with a fresh air inlet 301 at its bottom, and the fresh air inlet 301 communicates with the air inlet chamber 331; the housing 300 may be provided with a fresh air outlet 302 at its top or front side or left side or right side, and the fresh air outlet 302 communicates with the air outlet chamber 332. Optionally, the housing 300 is provided with a fresh air inlet 301 at its bottom and is open towards the rear side of the fresh air module 200 for air intake from the rear; the housing 300 is provided with a fresh air outlet 302 at its front side for air intake towards the front side of the fresh air module 200.

[0038] Please refer to Figures 3 to 5 As shown, when the fresh air module 200 is operating, fresh air enters the air inlet chamber 331 from the fresh air inlet 301, then passes through the ventilation holes 610 of the middle partition 600 and enters the air outlet chamber 332, and finally flows from the air outlet chamber 332 to the fresh air outlet 302 and is blown outwards through the fresh air outlet 302.

[0039] In the technical solution of the present invention, by constructing a first pre-positioning member 10 on the middle partition 600 and constructing a first mating member 30 corresponding to the first pre-positioning member 10 on the bottom case 310, during assembly, the first pre-positioning member 10 of the middle partition 600 can be first connected to the first mating member 30 of the bottom case 310 to position the middle partition 600 on the bottom case 310; then the cover 320 is covered on the bottom case 310 so that the middle partition 600 is surrounded between the cover 320 and the bottom case 310; finally, a connecting member is used to penetrate and connect the cover 320, the middle partition 600 and the bottom case 310. Since the middle partition 600 is positioned on the bottom case 310 before the connecting member is penetrated, it can be ensured that the middle partition 600 is difficult to move during the process of penetrating the connecting member, so that the connecting member can accurately penetrate and connect the foregoing three without being easily misaligned. The connecting member may be a structure with a connecting function such as a screw or a pin.

[0040] Please refer to Figure 8 In an embodiment, the middle partition 600 is constructed with a plurality of first pre-positioning members 10, and the plurality of first pre-positioning members 10 are arranged along the circumference of the middle partition 600; the bottom case 310 has a first cavity 311 that cooperates with the middle partition 600 to form the air outlet chamber 332, and a plurality of first mating members 30 are constructed on the circumference of the first cavity 311 to cooperate and connect with the plurality of first pre-positioning members 10.

[0041] Specifically, the middle partition plate 600 is installed at the open end of the first cavity 311 to cooperate with the first cavity 311 to form the air outlet cavity 332. Among them, a ventilation hole 610 is formed through the center part of the middle partition plate 600, and a plurality of first pre-positioning members 10 are constructed on the circumferential part of the middle partition plate 600; a plurality of first fitting members 30 are constructed on the outer wall surface or the inner wall surface of the circumference of the first cavity 311, and the plurality of first fitting members 30 and the plurality of first pre-positioning members 10 are respectively in one-to-one correspondence and cooperation. It can be seen from this that the middle partition plate 600 is pressed and positioned on the bottom case 310, so that the middle partition plate 600 is not easy to move.

[0042] Please refer to Figure 4 、 Figure 8 , in an embodiment, the bottom case 310 further has a second cavity 312 located on one side of the first cavity 311 and cooperating with the case cover 320 to form the air inlet cavity 331, and at least one of the first fitting members 30 is located on the common side wall of the first cavity 311 and the second cavity 312 and is located inside the second cavity 312.

[0043] Specifically, the case cover 320 is covered on the bottom case 310. Among them, a part of the case cover 320 covers above the second cavity 312 of the bottom case 310 and cooperates with the second cavity 312 to form the air inlet cavity 331; another part of the case cover 320 covers above the middle partition plate 600 and forms an air passing cavity 333 at an interval from the middle partition plate 600. The air passing cavity 333 communicates the air inlet cavity 331 and the ventilation hole 610 of the middle partition plate 600. As Figure 5 shown, when the fresh air module 200 works, the air flow enters through the fresh air inlet, and then enters the air outlet cavity 332 through the air inlet cavity 331, the air passing cavity 333, and the ventilation hole 610 of the middle partition plate 600, and finally blows out from the fresh air outlet 302.

[0044] Since the common side wall of the first cavity 311 and the second cavity 312 supports below the middle partition plate 600, if a slit is formed between the common side wall and the middle partition plate 600, the air flow in the air outlet cavity 332 may flow back to the air inlet cavity 331. In order to avoid this situation, at least one of the first fitting members 30 is arranged on the common side wall of the first cavity 311 and the second cavity 312, and it is defined that the first fitting member 30 is located inside the second cavity 312, so as to be connected to the corresponding first pre-positioning member 10 of the middle partition plate 600, thereby pressing the middle partition plate 600 on the common side wall of the first cavity 311 and the second cavity 312, avoiding a large slit between the two, and reducing the occurrence of air flow reverse backflow.

[0045] Please refer to Figure 4 and Figure 7, Further, the peripheral structure of the windward surface of the middle partition plate 600 has a sealing flange 620 that cooperates with the shell cover 320. The sealing flange 620 is provided with an air passage notch 621 at the position where the air passage cavity 333 and the first cavity 311 are butted. Specifically, a sealing slot corresponding to the sealing flange 620 is provided around the circumference of the shell cover 320 for the sealing flange 620 to be inserted, so as to seal the gap at the mating position between the middle partition plate 600 and the shell cover 320 and reduce the air volume leakage. The air passage notch 621 is provided on the sealing flange 620 to allow the air flow in the air inlet cavity 331 to enter the air passage cavity 333 and prevent the sealing flange 620 from blocking the air flow.

[0046] Please continue to refer to Figure 4 , Figure 8 , Based on any of the above embodiments, before the connecting member is inserted, the shell cover 320 may be likely to move and be misaligned, and it is also not easy for the connecting member to insert and connect the shell cover 320, the middle partition plate 600 and the bottom shell 310 in alignment. Therefore, in view of this, a plurality of second pre-positioning members 20 are further constructed around the circumference of the shell cover 320, and a plurality of second mating members 40 are constructed around the circumference of the bottom shell 310. The plurality of second mating members 40 are adapted to be connected to the plurality of second pre-positioning members 20 to position the shell cover 320 on the bottom shell 310.

[0047] During the process of assembling the fresh air module 200 described above, after the shell cover 320 is covered on the bottom shell 310, the second pre-positioning of the shell cover 320 and the second mating member 40 of the bottom shell 310 are also connected to position the shell cover 320 on the bottom shell 310; finally, a connecting member is used to insert and connect the shell cover 320, the middle partition plate 600 and the bottom shell 310. Since the middle partition plate 600 and the shell cover 320 have been positioned on the bottom shell 310 before the connecting member is inserted, it can be ensured that during the process of inserting the connecting member, it is difficult for the middle partition plate 600 and the shell cover 320 to move, and the connecting member can accurately align and insert the above three components without being easily misaligned, greatly reducing the assembly difficulty.

[0048] Further, a plurality of second pre-positioning members 20 of the housing cover 320 are arranged at intervals along its circumferential direction; a plurality of second mating members 40 of the bottom housing 310 are arranged at intervals along its outer peripheral wall, and a part of the first mating members 30 are located on the outer side wall of the first cavity 311 facing away from the second cavity 312, and another part of the first mating members 30 are located on the outer side wall of the second cavity 312 facing away from the first cavity 311. This can ensure that the housing cover 320 is connected and fixed to both the first cavity 311 and the second cavity 312 of the bottom housing 310, thereby improving the firmness of the installation of the housing cover 320 and reducing the occurrence of air leakage in the air inlet cavity 331 or the air outlet cavity 332 due to the appearance of slits at the periphery of the housing cover 320. In addition, the second pre-positioning members 20 on the housing cover 320 also need to be arranged in a staggered manner with the first pre-positioning members 10 on the middle partition plate 600 to avoid interference between the first pre-positioning members 10 and the second pre-positioning members 20 during assembly.

[0049] In any of the above embodiments, one of the first pre-positioning member 10 and the first mating member 30 is an elastic buckle, and the other is a buckle position adapted to the elastic buckle; and / or, one of the second pre-positioning member 20 and the second mating member 40 is an elastic buckle, and the other is a buckle position adapted to the elastic buckle. The elastic buckle can be a buckle ring arranged in a ring shape, or a hook arranged in a hook shape, etc.; correspondingly, the buckle position can be a protrusion for the buckle ring to hold, or a hook groove for the hook to hold.

[0050] In one embodiment, to facilitate the connection of the housing cover 320, the middle partition plate 600 and the bottom housing 310 by a connecting member, optionally, a plurality of connecting portions 50 are formed in a circumferential manner on the bottom housing 310; both the housing cover 320 and the middle partition plate 600 are provided with lugs 60 protruding laterally, and the connecting member passes through the lugs 60 of the housing cover 320 and the middle partition plate 600 in sequence, and then is connected to the connecting portion 50 of the bottom housing 310.

[0051] Specifically herein, three connecting portions 50 are formed in a circumferential manner on the bottom housing 310, and screw columns are formed on the connecting portions 50; correspondingly, screw holes corresponding to the screw columns are formed on the lugs 60 of both the housing cover 320 and the middle partition plate 600. After the middle partition plate 600 and the housing cover 320 are both positioned on the bottom housing 310, the connecting member passes through the screw holes of the lugs 60 of the housing cover 320 and the middle partition plate 600 in sequence, and then penetrates into the screw columns of the connecting portions 50 of the bottom housing 310, thereby realizing the connection of the housing cover 320, the middle partition plate 600 and the bottom housing 310 into an integral body. This can reduce the usage amount of the connecting member and achieve quick connection. After the bottom housing 310 is connected and fixed to the middle partition plate 600 and the housing cover 320 through the three connecting portions 50, the three connecting positions form a triangular stable structure, which is not easily loosened by activities and has better stability.

[0052] Please refer to Figures 4 to 6, in one embodiment, the fresh air module 200 further includes a fan assembly 400. The fan assembly 400 is installed in the first cavity 311 of the bottom shell 310. The fan assembly 400 includes a centrifugal impeller 410 and a motor 420. One end of the centrifugal impeller 410 is connected to the motor 420, and the other end of the centrifugal impeller 410 forms an air inlet end and corresponds to the ventilation hole 610 of the middle partition plate 600. During the operation of the fresh air module 200, the air flow in the air inlet cavity 331 passes through the ventilation hole 610 of the middle partition plate 600 and directly enters the inside of the centrifugal impeller 410 from the air inlet end of the centrifugal impeller 410, and then is thrown out at high speed by the centrifugal impeller 410, enhancing the air supply efficiency of the centrifugal impeller 410.

[0053] In addition, since the motor 420 of the fan assembly 400 is installed at the bottom of the first cavity 311 of the bottom shell, away from the ventilation hole 610 of the middle partition plate 600, it can avoid blocking the wind. And the motor 420 and the centrifugal impeller 410 can be installed in the first cavity 311 from the same side of the bottom shell 310, such as fixing with screws on the same side, without repeatedly adjusting the assembly direction, improving the assembly efficiency.

[0054] Please refer to Figures 4 to 6 , in one embodiment, the fresh air module 200 further includes a purification assembly 500. The purification assembly 500 is slidably installed on the middle partition plate 600 along the inside-outside direction of the housing 300 and is located on the air inlet side of the ventilation hole 610 of the middle partition plate 600.

[0055] Specifically, the housing 300 is provided with an installation opening on one side of the fresh air outlet 302. The installation opening is arranged in a long strip shape and extends in the same direction as one side edge of the fresh air outlet 302. The purification assembly 500 is slidably installed on the middle partition plate 600 from the installation opening. The user can pull out the purification assembly 500 from the installation opening for cleaning or replacement; or the purification assembly 500 can be pushed into the air inlet side of the ventilation hole 610 of the middle partition plate 600 to purify the air flow flowing from the air inlet cavity 331 through the ventilation hole 610 into the air outlet cavity 332, removing pollutants in the air.

[0056] As for the structure of the purification assembly 500, there can be various design schemes and there is no limitation here. For example but not limited to: the purification assembly 500 includes an installation frame 510 and a purification member 520 installed on the installation frame 510. The purification member 520 is applicable to remove any one or more of air pollutants such as dust, fine particulate matter, microorganisms, organic volatile gases (such as formaldehyde, etc.) in the air. The specific type of the purification member 520 can be selected according to its function. The purification member 520 can be any one or a combination of two of a common filter screen, a HEPA net, a formaldehyde remover, an IFD filter; it can also be any one or a combination of multiple of a primary filter screen, a medium-efficiency filter screen, and a high-efficiency filter screen.

[0057] In addition, since the air inlet end of the fan assembly 400 corresponds to the ventilation hole 610, it is equivalent that the purification assembly 500 corresponds to the air inlet end of the fan assembly 400. The air flow in the air inlet chamber 331 is first purified by the purification assembly 500 into relatively clean fresh air, and then the clean fresh air enters the air inlet end of the fan assembly 400 through the ventilation hole 610, and finally is blown out radially by the fan assembly 400. Relative to the air inlet chamber 331, the air passing chamber 333 between the middle partition 600 and the housing cover 320 has a relatively large space, so that the purification surface through which the purification assembly 500 supplies air for purification can be designed to be relatively large according to the size of the ventilation hole 610, thereby improving the efficiency of the purification assembly 500 in purifying air. Since the purification assembly 500 is designed to be relatively large, the amount of air that the purification assembly 500 can purify is correspondingly increased, thereby further extending the service life of the purification assembly 500 and extending the cycle of replacing the purification assembly 500.

[0058] Please refer to Figure 1 and Figure 2 , the present invention also provides an air conditioner 100, which includes a housing 110 and a fresh air module 200 installed in the housing 110. The specific structure of the fresh air module 200 refers to the above embodiments. Since the air conditioner 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. The air conditioner 100 is any one of a wall-mounted air conditioner indoor unit, a cabinet-type air conditioner indoor unit, an air machine, a ceiling-mounted air conditioner indoor unit, or a mobile air conditioner. Hereinafter, the air conditioner 100 is taken as an example of a wall-mounted air conditioner indoor unit for introduction and description.

[0059] In one embodiment, the housing 110 is provided with an air inlet 101, a first air outlet 102, and a second air outlet 103; wherein, the air inlet 101 and the first air outlet 102 are communicated. The fresh air module 200 is installed in the housing 110.

Thus, the air conditioner 100 has an indoor air circulation mode and a fresh air mode, wherein:

[0060] In the indoor air circulation mode, the air in the indoor environment enters the interior of the housing 110 through the air inlet 101, is heat-exchanged by the heat exchange component inside the housing 110 to form cold air or hot air, and then is blown back into the indoor environment from the first air outlet 102 to realize indoor air circulation;

[0061] In the fresh air mode, the air in the outdoor environment enters the fresh air module 200 through the fresh air pipe 700, is purified by the purification component 500 of the fresh air module 200 to form clean fresh air, and then is blown from the fresh air outlet 302 of the fresh air module 200 to the second air outlet 103 of the cabinet 110, and finally is blown from the second air outlet 103 into the indoor environment, so as to supplement fresh air to the indoor environment.

[0062] Optionally, the cabinet 110 includes a chassis 111, a front frame 112 and a panel 113. The end of the panel 113 is provided with a second air outlet 103; the fresh air module 200 is installed at the end of the chassis 111, and the fresh air module 200 is provided with a fresh air outlet 302 corresponding to the second air outlet 103 on the front side wall of the air outlet cavity 332, so that the air conditioner 100 sends out fresh air forward, so that the fresh air can accurately reach the position where the user is located.

[0063] In addition, to avoid direct blowing of fresh air on the user, the second air outlet 103 can be optionally composed of a plurality of micropores penetrating through the panel 113. After the fresh air is blown out from the plurality of micropores, the air flow is broken up into strands of smaller filamentous air flows, the wind speed is reduced, and the air flow becomes gentle and will not directly blow on the user, avoiding discomfort to the user.
