For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figures 1-6 As shown, the air conditioner 100 according to the embodiment of the utility model comprises a chassis 1, a fresh air component 2 and an adapter 3. The chassis 1 has an adapter 121, the fresh air component 2 is arranged on the chassis 1, the fresh air component 2 has a fresh air inlet 24 opposite to and connected to the adapter 121, the adapter 3 is connected to one end of the adapter 121 away from the fresh air inlet 24, and the adapter 3 is used to connect the fresh air duct.

[0039] It can be understood that the air conditioner 100 is installed indoors. There is a hole in the wall that connects the indoor environment and the outdoor environment. The fresh air duct passes through the hole and is connected to the air inlet of the adapter 3, so that the outdoor air flow entering the fresh air duct can flow into the adapter 3 from the air inlet of the adapter 3, and is connected to one end of the adapter interface 121 away from the fresh air inlet 24 through the adapter 3. The fresh air inlet 24 is opposite to and communicates with the adapter interface 121. Thus, the outdoor air flow can flow into the fresh air component 2 from the air outlet of the adapter 3 through the adapter interface 121 and the fresh air inlet 24 in sequence, thereby introducing the outdoor air flow 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.

[0040] At the same time, through such a setting, the fresh air duct and the fresh air component 2 are indirectly connected through the chassis 1 and the adapter 3. Thus, while ensuring that the outdoor air flow in the fresh air duct is introduced into the fresh air component 2 through the fresh air inlet 24, the fresh air component 2 can be independent of the fresh air duct, so that the fresh air component 2 can be separately disassembled and installed from the chassis 1 without affecting the fresh air duct, simplifying the maintenance and installation steps of the fresh air component 2, improving the disassembly and assembly efficiency, and reducing the maintenance cost of the fresh air component 2.

[0041] Furthermore, the fresh air component 2 includes a fan and a filter assembly. The fan and the filter assembly are arranged in the fresh air duct of the fresh air component 2. The fresh air inlet 24 is communicated with the fresh air outlet 25 through the fresh air duct. Thus, under the action of the fan, the outdoor air flow entering the fresh air duct through the fresh air inlet 24 is filtered by the filter assembly and then flows from the fresh air outlet 25 to the indoor space where the air conditioner 100 is located.

[0042] Even further, the fresh air component 2 also has an indoor air inlet 26. The indoor air inlet 26 is communicated with the fresh air outlet 25 through the fresh air duct. Thus, under the action of the fan, the indoor air flow entering the fresh air duct through the indoor air inlet 26 is filtered by the filter assembly and then flows from the fresh air outlet 25 to the indoor space where the air conditioner 100 is located.

[0043] According to the air conditioner 100 of the embodiment of the present invention, the chassis 1 has an adapter interface 121. The fresh air component 2 is arranged on the chassis 1. The fresh air component 2 has a fresh air inlet 24 that is opposite to and communicates with the adapter interface 121. The adapter 3 is connected to one end of the adapter interface 121 away from the fresh air inlet 24. The adapter 3 is used to connect the fresh air duct. While ensuring that the outdoor air flow in the fresh air duct is introduced into the fresh air component 2 through the fresh air inlet 24, the fresh air component 2 can be independent of the fresh air duct, so that the fresh air component 2 can be separately disassembled and installed from the chassis 1 without affecting the fresh air duct, simplifying the maintenance and installation steps of the fresh air component 2, improving the disassembly and assembly efficiency, and reducing the maintenance cost of the fresh air component 2.

[0044] In some embodiments of the present invention, such as Figure 6and Figure 7 As shown in Figure 7 , the fresh air component 2 has a first sealing groove 21, and the first sealing groove 21 surrounds the fresh air inlet 24. The air conditioner 100 further includes a sealing ring 4. Among them, the sealing ring 4 is located in the first sealing groove 21 and abuts against the chassis 1. Thus, the sealing performance between the fresh air component 2 and the base at the fresh air interface and the adapter 121 is ensured through the sealing ring 4, thereby preventing air leakage between the fresh air component 2 and the base, ensuring that all the air flow in the fresh air duct can flow into the fresh air component 2, and improving the reliability of the air conditioner 100.

[0045] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the fresh air component 2 is provided with a first protruding portion 22 and a second protruding portion 23 surrounding the fresh air inlet 24. The first protruding portion 22 surrounds the second protruding portion 23 and is spaced apart. A first sealing groove 21 is defined between the first protruding portion 22 and the second protruding portion 23. Thus, the first sealing groove 21 is defined by the fresh air component 2, the first protruding portion 22 and the second protruding portion 23, and the open end of the first sealing groove 21 faces the adapter 121, so that the sealing ring 4 can be located in the first sealing groove 21 and abut against the base, ensuring the sealing effect between the fresh air component 2 and the base.

[0046] Furthermore, the second protruding portion 23 protrudes from the inner peripheral wall of the fresh air inlet 24 towards the adapter 121. Thus, through such a setting, the sealing performance between the fresh air component 2 and the base is further ensured, and the overall reliability is improved.

[0047] In some embodiments of the present invention, the chassis 1 and the adapter 3 are snap-connected. Thus, the connection between the two is realized through the snap connection between the chassis 1 and the adapter 3, ensuring the reliability of the air flow in the fresh air duct flowing into the fresh air component 2. At the same time, the snap connection usually has a simple and fast installation process, without complex tools or cumbersome steps, improving efficiency and facilitating disassembly, assembly and maintenance.

[0048] In some embodiments of the present invention, as Figure 6 , Figure 8 and Figure 9 shown, the chassis 1 is provided with a second sealing groove 122, and the second sealing groove 122 surrounds the adapter 121. One end of the adapter 3 is inserted into the second sealing groove 122. Thus, the sealing performance between the adapter 3 and the base is ensured by inserting one end of the adapter 3 into the second sealing groove 122, thereby preventing air leakage between the adapter 3 and the base, ensuring that all the air flow in the fresh air duct can flow into the fresh air component 2, and improving the reliability of the air conditioner 100.

[0049] In some embodiments of the present invention, as Figure 6 , Figure 8 andFigure 9 As shown in the figure, on the chassis 1, there are a third protrusion 123 and a fourth protrusion 124 surrounding the adapter 121. The third protrusion 123 surrounds the fourth protrusion 124 and is spaced apart. A second sealing groove 122 is defined between the third protrusion 123 and the fourth protrusion 124. Thus, the second sealing groove 122 is defined by the chassis 1, the third protrusion 123 and the fourth protrusion 124, and the open mouth of the second sealing groove 122 faces the adapter 3, so that one end of the adapter 3 can be inserted into the second sealing groove 122 to ensure the sealing between the adapter 3 and the base.

[0050] Furthermore, the fourth protrusion 124 protrudes from the inner peripheral wall of the adapter 121 towards the adapter 3. Thus, through such a setting, the sealing between the adapter 3 and the base is further ensured, and the overall reliability is improved.

[0051] In some embodiments of the present utility model, as Figure 6 、 Figure 8 and Figure 9 shown, a step portion 31 is provided on the inner peripheral wall of the adapter 3, and the step portion 31 abuts against the third protrusion 123. It can be understood that since one end of the adapter 3 is inserted into the second sealing groove 122 defined between the third protrusion 123 and the fourth protrusion 124, and the third protrusion 123 surrounds the fourth protrusion 124 and is spaced apart. Thus, by the step portion 31 on the inner peripheral wall of the adapter 3 abutting against the third protrusion 123, the connection reliability between the adapter 3 and the base is ensured, thereby ensuring the sealing between the adapter 3 and the base, further preventing air leakage between the adapter 3 and the base, and improving the reliability of the air conditioner 100.

[0052] In some embodiments of the present utility model, as Figure 6 、 Figure 8 and Figure 9 shown, a flanging 32 is provided on the outer peripheral wall of the adapter 3, and the flanging 32 abuts against the fourth protrusion 124. It can be understood that since one end of the adapter 3 is inserted into the second sealing groove 122 defined between the third protrusion 123 and the fourth protrusion 124, and the third protrusion 123 surrounds the fourth protrusion 124 and is spaced apart. Thus, by the flanging 32 on the outer peripheral wall of the adapter 3 abutting against the fourth protrusion 124, the connection reliability between the adapter 3 and the base is ensured, thereby ensuring the sealing between the adapter 3 and the base, further preventing air leakage between the adapter 3 and the base, and improving the reliability of the air conditioner 100.

[0053] In some embodiments, as Figure 6 、 Figure 8 and Figure 9As shown, a stepped portion 31 is provided on the inner peripheral wall of the adapter 3. The stepped portion 31 abuts against the third protruding portion 123. A flanging 32 is provided on the outer peripheral wall of the adapter 3, and the flanging 32 abuts against the fourth protruding portion 124. Thus, by the abutment of the stepped portion 31 on the inner peripheral wall of the adapter 3 against the third protruding portion 123 and the abutment of the flanging 32 on the outer peripheral wall of the adapter 3 against the fourth protruding portion 124, the connection reliability between the adapter 3 and the base is further ensured, thereby ensuring the sealing performance between the adapter 3 and the base, further preventing air leakage between the adapter 3 and the base, and improving the reliability of the air conditioner 100.

[0054] In some embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9 shown, a groove 1241 is provided on the inner peripheral wall of the fourth protruding portion 124, and a protrusion 33 matching the groove 1241 is provided on the outer peripheral wall of the adapter 3. Thus, during the process of inserting one end of the adapter 3 between the third protruding portion 123 and the fourth protruding portion 124 and defining it in the second sealing groove 122, the cooperation between the groove 1241 and the protrusion 33 plays a role of pre-positioning and anti-mistake, reducing the assembly difficulty and improving the assembly efficiency.

[0055] In some embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9 shown, a first clamping portion 34 is provided on the outer peripheral wall of the adapter 3, and a second clamping portion 1242 matching the first clamping portion 34 is provided on the outer peripheral wall of the fourth protruding portion 124. Thus, during the process of inserting one end of the adapter 3 between the third protruding portion 123 and the fourth protruding portion 124 and defining it in the second sealing groove 122, the cooperation between the first clamping portion 34 and the second clamping portion 1242 plays a role of pre-positioning and anti-mistake, reducing the assembly difficulty and improving the assembly efficiency. At the same time, the cooperation between the first clamping portion 34 and the second clamping portion 1242 further ensures the connection reliability between the adapter 3 and the base, thereby ensuring the sealing performance between the adapter 3 and the base.

[0056] In some embodiments of the present invention, such as Figure 6 , Figure 8 and Figure 9 shown, the first clamping portion 34 includes a connecting section 341 and a hook 342. The connecting section 341 extends towards the direction of the transfer interface 121, and the hook 342 is connected to one end of the connecting section 341 close to the transfer interface 121. The second clamping portion 1242 includes a supporting section 1243. The supporting section 1243 is spaced apart from the fourth protruding portion 124, and a clamping groove 1244 matching the hook 342 is provided on the supporting section 1243.

[0057] Thus, during the process of inserting one end of the adapter 3 into the second sealing groove 122 defined between the third protrusion 123 and the fourth protrusion 124, the support section 1243 is spaced apart from the fourth protrusion 124, so that the connecting section 341 can extend between the support section 1243 and the fourth protrusion 124, enabling the hook 342 to extend into the card slot 1244, thereby realizing the engagement of the first engaging portion 34 and the second engaging portion 1242, further ensuring the connection reliability between the adapter 3 and the base, and thus ensuring the sealing performance between the adapter 3 and the base.

[0058] Furthermore, in the direction from the adapter port 121 to the adapter 3, the side wall surface of the hook 342 facing away from the fourth protrusion 124 is inclined in the direction away from the fourth protrusion 124. It can be understood that since the connecting section 341 extends between the support section 1243 and the fourth protrusion 124, with such a setting of the side wall surface of the hook 342 facing away from the fourth protrusion 124, it is convenient for the hook 342 to extend into the card slot 1244, reducing the assembly difficulty between the two and improving the assembly efficiency.

[0059] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the chassis 1 includes a seat body 11 and a connecting seat 12. Among them, the fresh air component 2 is connected to the seat body 11, the connecting seat 12 is connected to the seat body 11, the adapter port 121 is provided on the connecting seat 12, and the adapter 3 is located inside the connecting seat 12 and connected to the connecting seat 12. Thus, the connection between the fresh air component 2 and the chassis 1 is realized by connecting the fresh air component 2 to the connecting seat 12, thereby realizing the fixation of the fresh air component 2. At the same time, since the adapter 3 is located inside the connecting seat 12 and connected to the connecting seat 12, the connecting seat 12 plays a certain protective role for the adapter 3, improving the reliability of the overall structure, ensuring that the air flow in the fresh air duct can smoothly flow into the fresh air component 2, and improving the reliability of the air conditioner 100.

[0060] In some embodiments, as Figures 2-6 shown, the connecting seat 12 is provided with a second sealing groove 122, the second sealing groove 122 is arranged around the adapter port 121, one end of the adapter 3 is inserted into the second sealing groove 122, the connecting seat 12 is provided with a third protrusion 123 and a fourth protrusion 124 surrounding the adapter port 121, the third protrusion 123 surrounds the fourth protrusion 124 and is spaced apart, and the second sealing groove 122 is defined between the third protrusion 123 and the fourth protrusion 124. Thus, through such a setting, the sealing performance between the adapter 3 and the connecting seat 12 is ensured, thereby preventing the air flow from leaking between the adapter 3 and the connecting seat 12, ensuring that all the air flow in the fresh air duct can flow into the fresh air component 2, and improving the reliability of the air conditioner 100.
