[0031] The air conditioner 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0032] As Figures 1-6 shown, the air conditioner 100 according to an embodiment of the present utility model includes a housing 1 and a fresh air connector 2. Among them, a fresh air inlet 11 is provided on the housing 1, and screw posts 12 are provided on the housing 1. The fresh air connector 2 is connected to the fresh air inlet 11. The fresh air connector 2 has a plurality of screw holes 2121 spaced apart in the circumferential direction of the fresh air connector 2, and one of the plurality of screw holes 2121 can be selectively connected to the screw post 12 through a fastener 3.

[0033] It can be understood that the air conditioner 100 is installed indoors, a hole is opened in the wall to communicate the indoor environment and the outdoor environment, a fresh air inlet 11 is provided on the housing 1 of the air conditioner 100, the fresh air connector 2 has an air inlet 23 and an air outlet 24, and a fresh air pipe can pass through the hole and be communicated with the air inlet 23 of the fresh air connector 2, and be communicated with the fresh air inlet 11 through the air outlet 24 of the fresh air connector 2, so that the outdoor air flow can flow into the fresh air connector 2 from the fresh air pipe through the air inlet 23 of the fresh air connector 2, thereby realizing the connection between the air conditioner 100 and the outdoor environment.

[0034] By selectively connecting one of the screw holes 2121 of the plurality of screw holes 2121 spaced apart along the circumferential direction of the fresh air connector 2 with the screw column 12 through the fastener 3, the fresh air connector 2 can be rotated along the circumferential direction of the fresh air inlet 11, so that the direction of the air inlet 23 of the fresh air connector 2 is adjusted while the air outlet 24 of the fresh air connector 2 is connected to the fresh air inlet 11, thereby changing the connection direction of the fresh air duct, so that the fresh air duct can extend from the air inlet 23 of the fresh air connector 2 to the hole of the wall in a relatively straight posture, so that the installation of the fresh air duct can be facilitated, the space occupied by the fresh air duct can be reduced, the distance between the air conditioner 100 and the wall can be shortened, the placement of the air conditioner 100 can be more flexible, and the air conditioner 100 can be adapted to different installation scenarios to improve the user experience. In addition, since the fresh air duct does not need to maintain an S-shaped shape, it can simultaneously solve the problem of the air conditioner 100 being pushed away from the wall by the action of the fresh air duct and the air volume loss caused by the folded pipe, thereby improving the reliability of the air conditioner 100.

[0035] At the same time, the fresh air connector 2 of the present application has a simple structure and can change the connection direction of the fresh air duct without other switching structures, thereby effectively reducing the cost of the air conditioner 100.

[0036] Specifically, in Figure 1 and Figure 2 In the embodiment of the air conditioner 100 shown, assuming that the indoor unit of the air conditioner 100 is placed against a corner, the hole may be set in any one of the left and right walls of the corner. If the hole is set in the right wall, the fresh air connector 2 is rotated to make its air inlet 23 face the right wall, and one of the multiple screw holes 2121 corresponds to the screw column 12, so that the fastener 3 is passed through the screw column 12 and the screw hole 2121 corresponding to the screw column 12, so that the fresh air connector 2 is installed, and the fresh air duct is connected to the air inlet 23 of the fresh air connector 2 and can The air inlet 23 of the fresh air connector 2 can be extended to the hole in a generally straight shape, and extend to the outdoor space through the hole; or, if the hole is set on the left wall, the fresh air connector 2 is rotated so that its air inlet 23 faces the left wall, and one of the multiple screw holes 2121 corresponds to the screw column 12, so that the fastener 3 is passed through the screw column 12 and the screw hole 2121 corresponding to the screw column 12, so as to realize the installation of the fresh air connector 2, and the fresh air duct is connected to the air inlet 23 of the fresh air connector 2 and can be extended to the hole in a generally straight shape, and extend to the outdoor space through the hole. In this way, the air conditioner 100 of the present application can adapt to different installation environment conditions and improve the installation efficiency of the air conditioner 100.

[0037] like Figure 3As shown, when the air conditioner 100 is installed at some special locations, for example, when there is already a hole in the wall and it is located below the fresh air inlet 11, the fresh air connector 2 is rotated so that its air inlet 23 faces downward, and one of the plurality of screw holes 2121 in the plurality of screw holes 2121 corresponds to the screw post 12. Thus, the fastener 3 is passed through the screw post 12 and the screw hole 2121 corresponding to the screw post 12 to realize the installation of the fresh air connector 2. And the fresh air duct includes a first section and a second section. The first section is connected to the air inlet 23 of the fresh air connector 2, and the second section extends through the hole to the outdoor space, so that the fresh air duct can extend in a substantially straight form.

[0038] It should be noted that the matching structure between the fresh air connector 2 and the housing 1 of the present application is not limited to being applied to the fresh air inlet 11 of the fresh air module, and can also be applied to other body air outlets. For example, in an embodiment where the air conditioner 100 is configured as an integrated machine, the body air outlet further includes an outdoor air outlet 24 provided on the housing 1. The outdoor air outlet 24 can be connected to the outdoor air duct through the above-mentioned matching structure between the fresh air connector 2 and the housing 1, so as to facilitate the user to adjust the direction and trend of the outdoor air duct, thereby facilitating the operation of extending and arranging the outdoor air duct outdoors.

[0039] According to the air conditioner of the embodiment of the present utility model, the housing 1 is provided with a fresh air inlet 11, the housing 1 has a screw post 12, the fresh air connector 2 is connected to the fresh air inlet 11, and the fresh air connector 2 has a plurality of screw holes 2121 spaced apart along the circumferential direction of the fresh air connector 2. One of the plurality of screw holes 2121 can be selectively connected to the screw post 12 through the fastener 3, so that the fresh air connector 2 can rotate along the circumferential direction of the fresh air inlet 11. Thus, while the air outlet 24 of the fresh air connector 2 is communicated with the fresh air inlet 11, the orientation of the air inlet 23 of the fresh air connector 2 is adjusted, and then the connection direction of the fresh air duct is changed, which is convenient for the installation of the fresh air duct, reduces the space occupied by the fresh air duct, shortens the distance between the air conditioner 100 and the wall, makes the placement of the air conditioner 100 more flexible, facilitates the air conditioner 100 to adapt to different installation scenarios, and improves the user experience. And, since the fresh air duct does not need to maintain an S-shaped form, the problems that the air conditioner 100 is pushed away from the wall by the fresh air duct and the air volume loss caused by the bent duct can be solved at the same time, and the reliability of the air conditioner 100 is improved.

[0040] In some embodiments of the present utility model, there is one screw post 12, and one of the plurality of screw holes 2121 can be selectively connected to the screw post 12 through the fastener 3. Thus, through such a setting, while the air outlet 24 of the fresh air connector 2 is communicated with the fresh air inlet 11, the orientation of the air inlet 23 of the fresh air connector 2 is adjusted, and then the connection direction of the fresh air duct is changed. In addition, the design with one screw post 12 is relatively simple, reducing the complexity and cost in at least the process.

[0041] In some embodiments of the present utility model, there are multiple screw posts 12, and the multiple screw posts 12 are spaced apart along the circumferential direction of the fresh air inlet 11. One of the multiple screw holes 2121 can be selectively connected to one of the screw posts 12 through a fastener 3. Thus, through such a setting, while the air outlet 24 of the fresh air joint 2 is communicated with the fresh air inlet 11, the orientation of the air inlet 23 of the fresh air joint 2 is adjusted, and further the connection direction of the fresh air pipe is changed. In addition, by having multiple screw posts 12, the assembly difficulty can be reduced and the assembly efficiency can be improved.

[0042] It should be noted that Figure 5 two screw posts 12 are shown for illustrative purposes, but those of ordinary skill in the art can clearly understand after reading the following technical solution that applying this solution to a technical solution with three or more screw posts 12 also falls within the protection scope of the present utility model.

[0043] In some embodiments of the present utility model, as Figures 4-6 shown, the housing 1 is snap-connected to the fresh air joint 2. Thus, before the screw hole 2121 and the screw post 12 are connected through the fastener 3, pre-positioning can be achieved through the snap connection between the housing 1 and the fresh air joint 2, which is convenient for the screw hole 2121 and the screw post 12 to pass through the fastener 3, reduces the assembly difficulty, and improves the assembly efficiency. At the same time, the snap connection between the housing 1 and the fresh air joint 2 further improves the connection reliability between the two, thereby improving the reliability of the air conditioner 100.

[0044] In some embodiments of the present utility model, as Figures 4-6 shown, the housing 1 has a card slot 13, and the card slot 13 is a plurality of evenly spaced along the circumferential direction of the fresh air inlet 11. The fresh air joint 2 has a plurality of card protrusions 2122 that cooperate with the plurality of card slots 13. Thus, the snap connection between the housing 1 and the fresh air joint 2 is achieved through the cooperation of the card protrusions 2122 and the card slots 13, and by having the card slots 13 be a plurality of evenly spaced along the circumferential direction of the fresh air inlet 11 and the card protrusions 2122 be a plurality that cooperate with the plurality of card slots 13, the connection reliability between the two is further improved.

[0045] In some embodiments of the present utility model, as Figures 4-6 shown, the card slot 13 is formed by protruding from the inner peripheral wall of the fresh air inlet 11 towards the radially outward direction. Thus, through such a setting, the connection airtightness between the fresh air inlet 11 and the air inlet 23 of the fresh air joint 2 is ensured, and the inner peripheral wall of the fresh air inlet 11 and the inner wall surface of the fresh air interface can be set to be substantially smooth, which is beneficial to improving the smoothness of gas flow and reducing unnecessary eddy current phenomena.

[0046] In some embodiments of the present utility model, as Figure 6As shown in the figure, the fresh air connector 2 includes a first connector 21 and a second connector 22. The first connector 21 extends in the horizontal direction and has a first channel. One end of the first channel communicates with the fresh air inlet 11. A plurality of screw holes 2121 are provided on the first connector 21. One end of the second connector 22 is connected to the end of the first connector 21 facing away from the fresh air inlet 11. The extending direction of the second connector 22 is perpendicular to the extending direction of the first connector 21. The second connector 22 has a second channel. One end of the second channel communicates with the end of the first channel facing away from the fresh air inlet 11.

[0047] It can be understood that the outlet of the first channel forms the air outlet 24 of the fresh air connector 2, and the inlet of the second channel forms the air inlet 23 of the fresh air connector 2. The outdoor air flow enters the second channel through the fresh air pipe and the inlet of the second channel, and communicates with the fresh air inlet 11 through the first channel and the outlet of the first channel, so that the outdoor air flow can flow into the fresh air connector 2 from the fresh air pipe through the air inlet 23 of the fresh air connector 2, thereby realizing the connection between the air conditioner 100 and the outdoor environment.

[0048] At the same time, by making the extending direction of the second connector 22 perpendicular to the extending direction of the first connector 21, and optionally connecting one of the plurality of screw holes 2121 spaced apart in the circumferential direction of the fresh air connector 2 to the screw post 12 through the fastener 3, while the air outlet 24 of the fresh air connector 2 communicates with the fresh air inlet 11, the second connector 22 can be rotated along the circumferential direction of the fresh air inlet 11, so as to adjust the orientation of the air inlet 23 of the fresh air connector 2, and further change the connection direction of the fresh air pipe, so that the fresh air pipe can extend from the air inlet 23 of the fresh air connector 2 to the hole in the wall in a relatively straight posture. In this way, the installation of the fresh air pipe can be facilitated, the space occupied by the fresh air pipe can be reduced, the distance between the air conditioner 100 and the wall can be shortened, the placement of the air conditioner 100 can be made more flexible, the air conditioner 100 can be made to adapt to different installation scenarios, and the user experience can be improved. And, since the fresh air pipe does not need to maintain an S-shaped form, the problems that the air conditioner 100 is pushed away from the wall by the fresh air pipe and the air volume loss caused by the bent pipe can be solved at the same time, and the reliability of the air conditioner 100 can be improved.

[0049] In some embodiments of the present invention, as Figure 6 shown, the first connector 21 includes a body portion 211. The first channel is provided inside the body portion 211 and extends along the length direction of the body portion 211. One end of the body portion 211 close to the fresh air inlet 11 has a flange 212. The flange 212 extends along the circumferential direction of the body portion 211. A plurality of screw holes 2121 are provided on the flange 212.

[0050] Thus, one of the multiple screw holes 2121 provided in the flanging 212 is optionally connected to the screw post 12 through the fastener 3, so as to connect the main body portion 211 to the housing 1, thereby realizing the connection between the fresh air joint 2 and the housing 1. At the same time, since the first channel is provided in the main body portion 211 and extends along the length direction of the main body portion 211, and the multiple screw holes 2121 are provided on the flanging 212, it is avoided that the connection between the screw holes 2121 and the screw post 12 through the fastener 3 destroys the airtightness and integrity of the first channel, which is beneficial to improving the smoothness of gas flow and reducing unnecessary eddy current phenomena.

[0051] In some embodiments of the present invention, as Figure 6 shown, the multiple screw holes 2121 include a first hole 2121a and a second hole 2121b, and the first hole 2121a and the second hole 2121b are located on the side of the flanging 212 away from the second joint 22. Thus, the first hole 2121a or the second hole 2121b is optionally connected to the screw post 12 through the fastener 3, so that the second joint 22 can rotate along the circumferential direction of the fresh air inlet 11. At the same time, since the extending direction of the second joint 22 is perpendicular to the extending direction of the first joint 21, and the first hole 2121a and the second hole 2121b are located on the side of the flanging 212 away from the second joint 22, the reliability of the cooperation between the first hole 2121a and the second hole 2121b and the screw post 12 is ensured.

[0052] In some embodiments, as Figure 5 and 6 shown, the multiple screw holes 2121 include a first hole 2121a and a second hole 2121b, and the first hole 2121a and the second hole 2121b are located on the side of the flanging 212 away from the second joint 22. The clamping protrusions 2122 are four evenly spaced along the circumferential direction of the flanging 212. Along the up and down direction of the air conditioner 100, one of the clamping protrusions 2122 is located between the first hole 2121a and the second hole 2121b, and the clamping grooves 13 are four evenly spaced along the fresh air inlet 11. Thus, the first hole 2121a or the second hole 2121b is optionally connected to the screw post 12 through the fastener 3, so that the second joint 22 can rotate along the circumferential direction of the fresh air inlet 11, and the reliability of the connection between the two is further improved through the cooperation of the clamping protrusions 2122 and the clamping grooves 13, thereby improving the reliability of the air conditioner 100.

[0053] In some embodiments of the present invention, the fresh air joint 2 is an integral part. Thus, it is convenient to connect the fresh air pipe adapter to the housing 1, simplifies the assembly process of the air conditioner 100, shortens the assembly time of the air conditioner 100, and improves the assembly efficiency of the air conditioner 100.

[0054] In some embodiments of the present utility model, the air conditioner 100 further includes a fresh air module. The fresh air module is disposed within the housing 1. The inlet of the fresh air module is in communication with the fresh air inlet 11. The outdoor air flow can sequentially pass through the fresh air duct and the fresh air connector 2 and enter the fresh air inlet 11, and finally enter the interior of the fresh air module from the inlet of the fresh air module, introducing outdoor fresh air into the room, realizing the fresh air function, and being able to improve the indoor air quality to a certain extent and enhance the user experience.
