[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0062] The following is for reference. Figures 1-16 Description of an indoor air conditioning unit 100 according to an embodiment of the present utility model.

[0063] refer to Figures 1-3 According to the first aspect of the present invention, the indoor unit 100 of the air conditioner includes: an indoor unit housing 10, a heat exchange and air supply assembly, and an air outlet module 20.

[0064] The indoor unit casing 10 has an air duct 17, an air inlet, and an indoor air outlet 18. The air duct 17 connects the air inlet and the indoor air outlet 18. Airflow enters the indoor unit casing 10 through the air inlet and exits through the indoor air outlet 18. The indoor unit casing 10 serves to prevent dust and protect internal components. The air inlet on the indoor unit casing 10 is used to deliver indoor or outdoor air into the indoor unit casing 10, and the indoor air outlet 18 is used to exhaust treated air into the room. For example, the air inlet can be located at the top of the indoor unit casing 10, and the indoor air outlet 18 can be located at the lower front part of the indoor unit casing 10.

[0065] The heat exchange and air supply assembly is located inside the indoor unit casing 10 and includes a heat exchanger component and a fan component. The fan component includes a fan wheel and a motor. The motor is connected to the fan wheel to drive the fan wheel to rotate. The rotation axis of the fan wheel extends along a first direction. The fan wheel can be a cross-flow fan wheel. Both the heat exchanger component and the fan wheel are located within the air duct 17. The heat exchanger component can be located between the fan component and the air inlet. The heat exchange and air supply assembly is used to heat or cool the air entering the indoor unit casing 10 through the air inlet and discharge it from the indoor air outlet 18, thereby regulating the indoor air temperature.

[0066] For example, the fan unit drives air from the air inlet into the indoor unit casing 10, where it exchanges heat with the heat exchanger unit before being discharged into the room through the indoor air outlet 18, thus regulating the indoor temperature. The heat exchanger unit can be located between the fan unit and the air inlet. When the fan is working, it drives air from the air inlet into the indoor unit casing 10, where it exchanges heat with the heat exchanger unit, flows through the fan, and is then discharged into the room through the indoor air outlet 18.

[0067] For example, the first direction can be left or right.

[0068] The air outlet module 20 is located in the indoor unit housing 10, and the air outlet module 20 is used to introduce oxygen into the room.

[0069] For example, the air outlet module 20 can be installed on the indoor unit housing 10, or at least part of the air outlet module 20 can be integrally formed with the indoor unit housing 10. For example, a part of the air outlet module 20 can be integrally formed with the indoor unit housing 10, or the entire air outlet module 20 can be integrally formed with the indoor unit housing 10.

[0070] For example, an outdoor oxygen generator 40 can introduce oxygen into an exhaust module 20 via an oxygen delivery pipeline, and the exhaust module 20 can then discharge the oxygen into the room.

[0071] According to the embodiment of the present utility model, the indoor unit 100 of the air conditioner is provided with an air outlet module 20, which is used to introduce oxygen into the room. In this way, the oxygen delivery pipeline can be connected to the air outlet module 20, making it more convenient to connect the oxygen delivery pipeline to the indoor unit 100 of the air conditioner.

[0072] refer to Figure 1 According to some embodiments of the present invention, at least a portion of the air outlet module 20 is located outside the air duct 17.

[0073] For example, at least a portion of the air outlet module 20 may be located outside the air duct 17. This could mean that a portion of the air outlet module 20 is located outside the air duct 17, or that the entire air outlet module 20 is located outside the air duct 17.

[0074] By positioning at least a portion of the exhaust module 20 outside the air duct 17, the obstruction of the exhaust module 20 to the airflow in the air duct 17 can be reduced, thereby reducing the flow resistance and flow noise of the airflow in the air duct 17.

[0075] refer to Figure 2 According to some embodiments of the present invention, the air outlet module 20 is detachably installed on the indoor unit housing 10.

[0076] For example, the connection between the air outlet module 20 and the indoor unit housing 10 can be a snap-fit ​​connection, a screw connection, etc.

[0077] By detachably installing the air outlet module 20 onto the indoor unit housing 10, the maintenance and replacement of the air outlet module 20 can be facilitated.

[0078] refer to Figures 3-4 According to some embodiments of the present invention, the air outlet module 20 includes an air outlet box 24, which has an air outlet chamber 21. The air outlet box 24 includes a detachably connected box body 242 and a box cover 241. The box cover 241 is provided with an air outlet hole 231, and the box body 242 is provided with an air inlet hole 22.

[0079] For example, the connection between the box body 242 and the box cover 241 can be a snap-fit ​​connection 243, a screw connection, etc.

[0080] By including a detachably connected body 242 and a cover 241, the outlet box 24 can be disassembled, facilitating maintenance and cleaning of its interior. With an outlet hole 231 on the cover 241 and an inlet hole 22 on the body 242, the inlet hole 22 and outlet hole 231 are located at different positions within the outlet box 24, facilitating connection of the oxygen delivery pipeline to the inlet hole 22.

[0081] refer to Figures 1-3 The air outlet module 20 has an air outlet chamber 21, an air inlet 22 and an air outlet 231. The air inlet 22 is connected to the air outlet chamber 21 and is used to introduce oxygen into the air outlet chamber 21. The air outlet 231 connects the air outlet chamber 21 with the room. The oxygen that enters the air outlet chamber 21 can be discharged into the room through the air outlet 231.

[0082] For example, there can be one air inlet 22; there can be one or more air outlets 231. When there are multiple air outlets 231, all of them are connected to the air outlet chamber 21.

[0083] For example, an outdoor oxygen generator 40 can deliver oxygen through an oxygen delivery pipeline, which enters the outlet chamber 21 through the inlet 22. The oxygen in the outlet chamber 21 is then discharged into the room through the outlet 231.

[0084] By providing an air inlet 22, an air outlet 231, and an air outlet chamber 21 connecting the air inlet 22 and the air outlet 231, the oxygen delivery pipeline can be connected to the air inlet 22 of the air outlet module 20, making it easier to connect the oxygen delivery pipeline to the indoor unit 100 of the air conditioner. When oxygen flows from the air inlet 22 of the air outlet module 20 to the air outlet chamber 21, the oxygen is buffered and its flow rate is reduced because it enters a larger cross-section space from a smaller cross-section space. If the oxygen is directly discharged into the room from the air outlet 231, noise such as whistling will be generated due to the excessive flow rate of the oxygen through the air outlet 231. By allowing the oxygen to flow from the air inlet 22 of the air outlet module 20 into the air outlet chamber 21, the air outlet chamber 21 can buffer and reduce the noise of the oxygen. In this way, when the oxygen in the air outlet chamber 21 is discharged into the room through the air outlet 231, the noise generated by the oxygen flow into the room can be reduced.

[0085] refer to Figures 3-4 According to some embodiments of this utility model, the number of air outlets 231 is multiple.

[0086] For example, multiple vents 231 can be circumferentially distributed in the vent module 20.

[0087] By having multiple vents 231, it is beneficial to disperse the oxygen when the vent module 20 discharges oxygen into the room, reduce the noise when the oxygen is discharged from the vents 231, and also accelerate the circulation of oxygen in the room.

[0088] refer to Figures 4-6 According to some embodiments of the present invention, one of the box body 242 and the box cover 241 is provided with a buckle 243, and the other of the box body 242 and the box cover 241 is provided with a fastening part 244 that cooperates with the buckle 243.

[0089] For example, the box body 242 may have a buckle 243 and the box lid 241 may have a fastening part 244 that cooperates with the buckle 243, or the box lid 241 may have a buckle 243 and the box body 242 may have a fastening part 244 that cooperates with the buckle 243.

[0090] For example, the number of buckles 243 can be one or more, and the number of fastening parts 244 can be one or more. When the number of fastening parts 244 and buckles 243 is multiple, the buckles 243 and fastening parts 244 are arranged circumferentially along the box body 242 or the box cover 241. The number of fastening parts 244 and buckles 243 can be the same, and the fastening parts 244 and buckles 243 correspond one-to-one.

[0091] By providing a buckle 243 on one of the box body 242 and the box cover 241 and a fastening part 244 that cooperates with the buckle 243 on the other, the installation and disassembly of the box body 242 and the box cover 241 can be made more convenient, and the connection between the box body 242 and the box cover 241 can be made more stable.

[0092] refer to Figures 4-6 According to some embodiments of the present invention, the opening edge of the box body 242 is provided with a first stop edge 245, and the opening edge of the box cover 241 is provided with a second stop edge 246, and the first stop edge 245 and the second stop edge 246 stop and abut against each other.

[0093] For example, the first stop edge 245 can be a protrusion that surrounds the opening edge of the box body 242 in the circumferential direction, and the second stop edge 246 can be a groove that surrounds the opening edge of the box cover 241 in the circumferential direction. When the box cover 241 is installed on the box body 242, the first stop edge 245 and the second stop edge 246 are engaged to splice the box cover 241 and the box body 242 together. Then, the buckle 243 is snapped into the fastening part 244 to fix the box cover 241 to the box body 242.

[0094] By providing a first stop edge 245 on the opening edge of the box body 242 and a second stop edge 246 on the opening edge of the lid 241, a guiding function can be provided during the installation of the box body 242 and the lid 241, facilitating the installation of the box body 242 and the lid 241. The stop edge 245 and the second stop edge 246 can make the connection between the box body 242 and the lid 241 tighter, reduce the gap between the box body 242 and the lid 241 after installation, and make the airtightness of the connection between the box body 242 and the lid 241 better, preventing oxygen from leaking from the assembly gap between the box body 242 and the lid 241.

[0095] refer to Figures 4-6 According to some embodiments of this utility model, the air outlet module 20 includes an air outlet box 24 and a sound-absorbing layer 25. The air outlet box 24 has an air outlet cavity 21, an air inlet 22, and an air outlet 231. The sound-absorbing layer 25 is fixed to the inner wall of the air outlet box 24. The sound-absorbing layer 25 has a porous structure and can play a role in sound absorption and noise reduction.

[0096] For example, the sound-absorbing layer 25 can be fixed to the inner wall of the air outlet box 24 by adhesive bonding.

[0097] By including an air outlet box 24 and a sound-absorbing layer 25 in the air outlet module 20, and fixing the sound-absorbing layer 25 to the inner wall of the air outlet box 24, the oxygen flow entering the air outlet chamber 21 from the air inlet 22 can reduce the noise of the oxygen flow after being absorbed by the sound-absorbing layer 25, thereby making the noise of the oxygen flow discharged from the air outlet 231 smaller.

[0098] According to some embodiments of this utility model, the sound-absorbing layer 25 is a sponge layer. By making the sound-absorbing layer 25 a sponge layer, the loose, porous, and soft properties of the sponge can be used to reduce noise and buffer the oxygen entering the air outlet chamber 21, thereby reducing the noise generated by the oxygen flowing through the air outlet box 24. The porous structure of the sponge can also absorb the noise of the oxygen airflow in the air outlet chamber 21, thereby reducing the noise of oxygen being discharged from the air outlet 231 into the room.

[0099] According to some embodiments of the present invention, the sound-absorbing layer 25 is made of hydrophobic or mildew-resistant materials.

[0100] For example, the sound-absorbing layer 25 can be made of plastic, rubber, etc.

[0101] By using a hydrophobic material for the sound-absorbing layer 25, condensation can be prevented from clogging the pores of the sound-absorbing layer 25, thus ensuring smooth airflow. Alternatively, by using a mildew-resistant material for the sound-absorbing layer 25, mold can be prevented from forming, and the oxygen flowing through the sound-absorbing layer 25 can be prevented from producing odors, thus keeping the oxygen released into the room fresh.

[0102] According to some embodiments of the present invention, the sound-absorbing layer 25 is disposed between the air inlet 22 and the air outlet 231.

[0103] For example, oxygen enters the exhaust module 20 through the air inlet 22, flows through the sound-absorbing layer 25 for noise reduction, and then flows out through the air outlet 231.

[0104] By placing the sound-absorbing layer 25 between the air inlet 22 and the air outlet 231, oxygen can flow fully through the sound-absorbing layer 25, thereby achieving a better noise reduction effect.

[0105] According to some embodiments of the present invention, the sound-absorbing layer 25 at least partially covers the side of the vent 231 facing the vent cavity 21. For example, the sound-absorbing layer 25 may partially cover the side of the vent 231 facing the vent cavity 21, or the sound-absorbing layer 25 may completely cover the side of the vent 231 facing the vent cavity 21. By ensuring that the sound-absorbing layer 25 at least partially covers the side of the vent 231 facing the vent cavity 21, the oxygen flow entering the vent cavity 21 can absorb sound and disperse the airflow through the porous sound-absorbing layer 25 as it flows towards the vent 231, resulting in lower noise and more uniform dispersion of the oxygen flow exiting the vent 231.

[0106] refer to Figures 4-6 According to some embodiments of the present invention, the air outlet box 24 includes a detachably connected box body 242 and a box cover 241. The box cover 241 is provided with an air outlet hole 231, and the box body 242 is provided with an air inlet hole 22. The air outlet box 24 has an air outlet chamber 21 inside. The sound-absorbing layer 25 is fixed to the inner wall of the box cover 241. The sound-absorbing layer 25 has a porous structure and can play the role of sound absorption and noise reduction.

[0107] For example, the sound-absorbing layer 25 can be fixed to the inner wall of the box cover 241 by adhesive bonding.

[0108] By fixing the sound-absorbing layer 25 to the inner wall of the box cover 241, the oxygen airflow entering the air outlet chamber 21 from the air inlet 22 can be directly discharged from the air inlet 22 on the box cover 241 after being absorbed by the sound-absorbing layer 25, thereby reducing the noise of the oxygen airflow and making the noise of the oxygen airflow discharged from the air outlet 231 smaller.

[0109] refer to Figure 6 According to some embodiments of the present invention, a first limiting rib 26 is provided inside the box body 242. The first limiting rib 26 abuts against the sound-absorbing layer 25 to limit the sound-absorbing layer 25.

[0110] For example, there can be one first limiting rib 26 or multiple first limiting ribs 26, and multiple first limiting ribs 26 can be arranged at intervals along the circumference of the box body 242.

[0111] By providing a first limiting rib 26 inside the box body 242 and abutting against the sound-absorbing layer 25 to limit the sound-absorbing layer 25, the sound-absorbing layer 25 is prevented from detaching from or moving from the inner wall of the box cover 241 under the blowing of oxygen, thus preventing the sound absorption effect of the sound-absorbing layer 25 from being reduced.

[0112] refer to Figures 4-6 According to some embodiments of the present invention, the air outlet module 20 is also provided with a water outlet hole 27, which is used to discharge water from the air outlet chamber 21.

[0113] For example, when the air outlet module 20 includes the air outlet box 24 described above, the water outlet 27 is provided on the air outlet box 24. For example, when the air outlet box 24 includes the box cover 241 and the box cover 241 described above, the water outlet 27 can be provided on the box body 242 of the air outlet module 20.

[0114] For example, the water outlet 27 can be connected to a water outlet pipe to discharge the water in the air outlet chamber 21.

[0115] By providing a water outlet hole 27 on the air outlet module 20, water in the air outlet chamber 21 is discharged, which avoids the accumulation of condensate in the air outlet chamber 21, reduces the water in the air outlet chamber 21 being sprayed into the room when oxygen passes through the air outlet hole 231, and also reduces the flow resistance of oxygen entering the air outlet chamber 21, thus reducing the noise generated by the oxygen flow through the air outlet chamber 21.

[0116] According to some embodiments of this utility model, a water outlet pipe is connected to the water outlet hole 27. The water outlet pipe is used to discharge the water in the air outlet chamber 21 into the water collection tray of the air conditioner indoor unit 100 or directly to the outside. Discharging the water in the air outlet chamber 21 into the water collection tray of the air conditioner indoor unit 100 through the water outlet pipe can reduce the space occupied by the water outlet pipe; or, the water outlet pipe can directly discharge the water in the air outlet chamber 21 to the outside, which can prevent condensate from accumulating in the air conditioner indoor unit 100 and causing the air conditioner indoor unit 100 to drip water.

[0117] refer to Figures 3-4 According to some embodiments of the present invention, the water outlet 27 and the air inlet 22 are located on the same side of the air outlet module 20.

[0118] For example, the water outlet 27 and the air inlet 22 can both be located on the rear side of the air outlet module 20.

[0119] By placing the water outlet 27 and the air inlet 22 on the same side of the air outlet module 20, it is convenient to also place the connecting pipes of the air inlet 22 and the water outlet 27 on the same side, such as the air inlet pipe and the water outlet pipe. This allows multiple connecting pipes to be arranged on the same side of the air outlet module 20, saving the space occupied by the connecting pipes.

[0120] refer to Figures 3-4According to some embodiments of the present invention, the water outlet 27 is located below the air inlet 22.

[0121] For example, when condensate is generated in the air outlet module 20, the condensate can be discharged through the water outlet 27 below the air inlet 22.

[0122] By placing the water outlet 27 below the air inlet 22, the water in the air outlet module 20 can be more easily discharged from the water outlet 27 along the bottom wall of the air outlet box 21 under the action of gravity, avoiding the accumulation of condensate in the air outlet module 20 and preventing condensate from clogging the air inlet 22 or flowing back into the oxygen delivery pipeline from the air inlet 22.

[0123] According to some embodiments of this utility model, the water outlet 27 is located below the air outlet 231.

[0124] For example, when condensate is generated in the air outlet module 20, the condensate can be discharged through the water outlet 27 below the air outlet 231.

[0125] By positioning the CNC 27 below the air outlet 231, water in the air outlet module 20 can be more easily discharged from the water outlet 27 along the bottom wall of the air outlet box 21 under the action of gravity, preventing condensate from accumulating in the air outlet module 20 and preventing water from being sprayed into the room when oxygen passes through the air outlet 231.

[0126] refer to Figure 1 According to some embodiments of the present invention, at least a portion of the air outlet module 20 is located on one side of the air duct 17 or the indoor air outlet 18 along a first direction, which is parallel to the rotation axis of the impeller or parallel to the extension direction of the indoor air outlet 18.

[0127] For example, at least a portion of the air outlet module 20 may be located on one side of the air duct 17 along the first direction. This could mean that a portion of the air outlet module 20 is located on one side of the air duct 17 along the first direction, or that the entire air outlet module 20 is located on one side of the air duct 17 along the first direction.

[0128] By placing at least a portion of the air outlet module 20 on one side of the air duct 17 along the first direction, the space of the air duct 17 along the first direction can be fully utilized, and the obstruction of the air outlet module 20 to the airflow within the air duct 17 or the airflow from the indoor air outlet 18 can be better reduced, thereby reducing airflow resistance within the air duct 17 and the airflow at the outlet, which helps to reduce noise. In addition, it also facilitates the connection of the oxygen delivery pipeline to the air outlet module 20.

[0129] refer to Figure 1According to some embodiments of this utility model, the first direction is left-right. The air outlet module 20 has an air outlet chamber 21, an air inlet 22, and an air outlet 231. The air inlet 22 communicates with the air outlet chamber 21 and is used to introduce oxygen into the air outlet chamber 21. The air outlet 231 connects the air outlet chamber 21 to the room. The air inlet 22 is located on the rear side of the air outlet module 20, and the air outlet 231 is located on the front side of the air outlet module 20. By placing the air inlet 22 on the rear side of the air outlet module 20, the arrangement and routing of the oxygen delivery pipeline can be facilitated when the oxygen delivery pipeline is connected to the air inlet 22, reducing the space occupied by the oxygen delivery pipeline, such as the air inlet pipe. By placing the air outlet 231 on the front side of the air outlet module 20, oxygen can be discharged into the room through the air outlet 231.

[0130] refer to Figure 1 According to some embodiments of this utility model, the air outlet module 20 is located on the air outlet side of the air duct 17, and the air outlet module 20 is located on one side of the indoor air outlet 18 along the first direction. By placing the air outlet module 20 on the air outlet side of the air duct 17, and the air outlet module 20 on one side of the indoor air outlet 18 along the first direction, the space along the first direction of the indoor air outlet 18 can be fully utilized, and the oxygen flowing out from the air outlet 231 of the air outlet module 20 can flow into a farther position in the room under the influence of the airflow discharged from the indoor air outlet 18.

[0131] According to some embodiments of this utility model, the fan component includes a motor connected to the impeller. The motor is located on one side of the impeller along a first direction. In the first direction, the motor and the air outlet module 20 are located on the same side of the heat exchange and air supply assembly. By placing the motor and the air outlet module 20 on the same side of the heat exchange and air supply assembly in the first direction, it is beneficial to utilize the space of the heat exchange and air supply assembly along the first direction and to make full use of the space near the motor. This makes the arrangement between the motor and the air outlet module 20 more compact, improves the space utilization rate inside the indoor unit casing 10, and helps to reduce the volume of the air conditioner indoor unit 100.

[0132] According to some embodiments of this utility model, the air outlet module 20 is located below the motor. By placing the air outlet module 20 below the motor, the space below the motor can be fully utilized, improving the space utilization rate within the indoor unit casing 10, and making the length of the air conditioner indoor unit 100 shorter in the first direction. In addition, by placing the air outlet module 20 below the motor, condensate generated on the air outlet module 20 can be prevented from dripping downwards onto the motor.

[0133] refer to Figure 1According to some embodiments of this utility model, the indoor unit housing 10 includes a chassis 11, and a heat exchange and air supply assembly and an air outlet module 20 are all mounted on the chassis 11. For example, both the heat exchange and air supply assembly and the air outlet module 20 can be detachably connected to the chassis 11. The chassis 11 serves to bear weight and provide support; by mounting both the heat exchange and air supply assembly and the air outlet module 20 on the chassis 11, the stability of their installation can be enhanced.

[0134] refer to Figure 1 According to some embodiments of this utility model, the first direction is the left-right direction. The indoor air outlet 18 is formed at the front end of the indoor unit housing 10, which facilitates the air conditioner indoor unit 100 to deliver air into the room. The front end of the indoor unit housing 10 includes a mounting part 19, which has a mounting opening 12. A mounting cavity 13 is formed inside the indoor unit housing 10. The mounting part 19 constitutes part of the cavity wall of the mounting cavity 13. The mounting cavity 13 communicates with the mounting opening 12. The air outlet module 20 is located inside the mounting cavity 13, and the air outlet module 20 has an air outlet part 23. The air outlet part 23 has an air outlet hole 231, and the air outlet part 23 is accommodated in the mounting opening 12.

[0135] For example, there can be one or more air outlets 231. When there are multiple air outlets 231, they can be evenly distributed on the air outlet section 23.

[0136] By forming an installation cavity 13 inside the indoor unit housing 10 and installing the air outlet module 20 inside the installation cavity 13, the stability of the installation of the air outlet module 20 can be enhanced. Furthermore, by accommodating the air outlet portion 23 of the air outlet module 20 in the installation port 12, the obstruction of the air outlet hole 231 of the air outlet module 20 by the indoor unit housing 10 can be reduced, allowing the air outlet hole 231 to discharge oxygen into the room more smoothly. With the indoor air outlet 18 formed at the front end of the indoor unit housing 10 and the installation port 12 formed on the front side of the indoor unit housing 10, the oxygen discharged from the air outlet hole 231 can flow into the room through the indoor air outlet 18.

[0137] refer to Figures 7-8 According to some embodiments of the present invention, the indoor unit housing 10 is provided with a mounting post 14 and a limiting structure 15 for limiting the air outlet module 20. The limiting structure 15 is provided in the mounting part 19, the mounting post 14 is located above the mounting cavity 13, and the upper side of the air outlet module 20 is provided with a mounting lug 28. The mounting lug 28 and the mounting post 14 are connected by fasteners.

[0138] For example, when the air outlet module 20 is installed into the indoor unit housing 10, the air outlet module 20 is installed into the mounting cavity 13, the limiting structure 15 limits the air outlet module 20, and the mounting lug 28 and the mounting post 14 are connected by fasteners, so that the air outlet module 20 can be fixed in the mounting cavity 13.

[0139] By connecting the mounting lug 28 to the mounting post 14 and limiting the air outlet module 20 by the limiting structure 15, the stability of the air outlet module 20 installed in the mounting cavity 13 can be improved, and the air outlet module 20 can be prevented from coming out of the mounting cavity 13.

[0140] refer to Figures 7-8 According to some embodiments of the present invention, the air outlet 23 faces forward and downward. By making the air outlet 23 face forward and downward, the oxygen discharged from the air outlet 231 can more easily flow into the room through the indoor air outlet 18.

[0141] refer to Figures 9-10 According to some embodiments of the present invention, the indoor unit housing 10 is provided with a limiting structure 15 for limiting the air outlet module 20. The limiting structure 15 includes a second limiting rib 151, which is disposed on the mounting part 19. The second limiting rib 151 and the mounting part 19 define a limiting groove 152 with the opening facing backward. The rear end of the air outlet module 20 is provided with a snap-fit ​​plate 29, which forms a snap-fit ​​groove 291 with the opening facing forward. The rear end of the second limiting rib 151 is inserted into the snap-fit ​​groove 291, and a portion of the snap-fit ​​plate 29 is inserted into the limiting groove 152.

[0142] For example, when installing the air outlet module 20 into the indoor unit housing 10, the snap-fit ​​plate 29 at the rear end of the air outlet module 20 can be aligned with the limiting groove 152, and the second limiting rib 151 can be aligned with the snap-fit ​​groove 291 formed on the snap-fit ​​plate 29. Then, the air outlet module 20 can be pushed into the mounting cavity 13, so that the rear end of the second limiting rib 151 is inserted into the snap-fit ​​groove 291, and part of the snap-fit ​​plate 29 is inserted into the limiting groove 152, so as to fix the air outlet module 20.

[0143] By inserting the rear end of the second limiting rib 151 into the snap-fit ​​groove 291 and part of the snap-fit ​​plate 29 into the limiting groove 152, the housing 242 of the air outlet module 20 can be supported, improving the stability of the air outlet module 20 in the mounting cavity 13 and preventing the air outlet module 20 from tipping over. The snap-fit ​​plate 29 can also serve as a guide, facilitating the installation of the air outlet module 20.

[0144] According to some embodiments of the present invention, the indoor unit housing 10 includes a front panel adjacent to the indoor air outlet 18, and a mounting portion 19 is located on one side of the indoor air outlet 18 along a first direction. The mounting portion 19 is closer to the rear end of the indoor unit housing 10 than the front panel.

[0145] For example, the exhaust module 20 can be detachably installed on the mounting section 19.

[0146] By positioning the mounting part 19 on one side of the indoor air outlet 18 along the first direction, oxygen can be discharged from the air outlet 231 of the air outlet module 20 and then discharged into the room through the indoor air outlet 18, which facilitates a rapid increase in the indoor oxygen content. Furthermore, by positioning the mounting part 19 closer to the rear end of the indoor unit housing 10 relative to the front panel, the air outlet module 20 is closer to the rear end of the indoor unit housing 10 when it is installed on the mounting part 19, thereby facilitating the connection between the air outlet module 20 and the oxygen delivery pipeline.

[0147] The air conditioner indoor unit 100 also includes an air guide plate 101, which is movably disposed on the indoor unit housing 10. The air guide plate 101 can open the air outlet and the mounting part 19 or close the indoor air outlet 18 and the mounting part 19.

[0148] By movably mounting the air guide plate 101 on the indoor unit housing 10, the air outlet module 20 can be visualized when the air guide plate 101 is open. When the indoor unit 100 is closed, the air guide plate 101 closes the indoor air outlet 18 and the mounting part 19, which can prevent dust accumulation in the air outlet part 23 of the air outlet module 20.

[0149] The surface of the air outlet 23 facing the air guide plate 101 is raised, recessed, or flush with the surface of the mounting part 19 facing the air guide plate 101.

[0150] By making the surface of the air outlet 23 facing the air guide plate 101 protrude or recess relative to the surface of the mounting part 19 facing the air guide plate 101, oxygen can be discharged from the indoor air outlet 18 into the room, and the air outlet 23 that discharges oxygen can be made more visually obvious. Alternatively, by making the surface of the air outlet 23 facing the air guide plate 101 flush with the surface of the mounting part 19 facing the air guide plate 101, oxygen can be discharged from the indoor air outlet 18 into the room, and the air outlet 23 can be made more aesthetically pleasing.

[0151] refer to Figures 1-2 According to some embodiments of the present invention, the first direction is the left-right direction. The indoor air outlet 18 is formed at the front end of the indoor unit housing 10. The front end of the indoor unit housing 10 has a mounting part 19. The mounting part 19 is provided with an air outlet 231. An installation cavity 13 is formed inside the indoor unit housing 10. The mounting part 19 constitutes part of the cavity wall of the installation cavity 13. The installation cavity 13 is connected to the air outlet 231. The air outlet module 20 is located inside the installation cavity 13. The air outlet module 20 has a box 242. The box 242 has an opening facing the air outlet 231.

[0152] For example, the box body 242 and the indoor unit housing 10 can be detachably connected, or the box body 242 and the indoor unit housing 10 can be integrally formed.

[0153] By forming a mounting portion 19 on the front side of the indoor unit housing 10, the mounting cavity 13 is connected to the air outlet 231, and the air outlet module 20 is located in the mounting cavity 13. This reduces the obstruction of the air outlet 231 of the air outlet module 20 by the indoor unit housing 10, allowing the air outlet 231 to discharge oxygen into the room more smoothly.

[0154] refer to Figures 11-13 According to some embodiments of the present invention, the indoor unit housing 10 includes an end plate 16, which is located at both ends of the indoor unit housing 10 along a first direction, and an air outlet module 20 is installed on the end plate 16. The air outlet module 20 is located on the inner or outer side of the end plate 16, and the air outlet module 20 has an air outlet hole 231 facing the outer side of the end plate 16.

[0155] For example, the indoor unit housing 10 has an end plate 16 at each end along the first direction, and the air outlet module 20 can be installed on one of the end plates 16. For example, the air outlet module 20 is installed on the end plate 16 located at the left or right end.

[0156] For example, the connection between the air outlet module 20 and the end plate 16 can be a detachable connection such as a snap-fit ​​connection 243 or a screw connection, or the air outlet module 20 and the end plate 16 can be integrally formed.

[0157] For example, the air outlet module 20 has an air outlet 231 facing the outside of the end plate 16. The air outlet 231 may be formed on the end plate 16, and the air outlet 231 of the air outlet module 20 may be connected to the air outlet 231 on the end plate 16. Alternatively, the air outlet module 20 and the end plate 16 may be integrally formed.

[0158] By installing the air outlet module 20 on the end plate 16, the space of the indoor unit housing 10 along the first direction can be fully utilized. The air outlet module 20 is installed at a position that is relatively closer to the sides of the indoor unit housing 10, reducing the space occupied by the air outlet module 20 on the heat exchange and air supply components and other internal structures of the indoor unit housing 10. By making the air outlet module 20 have an air outlet hole facing the outside of the end plate 16, it is convenient for the air outlet module 20 to discharge oxygen into the room.

[0159] refer to Figures 11-13 According to some embodiments of the present invention, the air outlet module 20 includes an air outlet 231, which is exposed on the outer surface of the indoor unit housing 10.

[0160] For example, the air vent 231 is exposed on the outer surface of the indoor unit housing 10. It can be the air vent 231 exposed on the front panel of the indoor unit housing 10 or the air vent 231 exposed on the bottom plate 411 of the indoor unit housing 10.

[0161] For example, the air outlet module 20 and the indoor unit housing 10 can be integrally formed.

[0162] By exposing the vent 231 on the outer surface of the indoor unit housing 10, the air outlet module 20 can directly discharge oxygen into the room through the vent 231, and the vent 231 for discharging oxygen can also be made more visually obvious.

[0163] refer to Figures 11-13 According to some embodiments of the present invention, the outer surface of the indoor unit housing 10 has an air outlet 231, and the air outlet module 20 is connected to the air outlet 231.

[0164] For example, the air vent 231 can be located on the outer surface of the indoor unit housing 10 or on the front panel of the indoor unit housing 10. The air vent 231 can be located in multiple places, and the air vent module 20 can be connected to all the air vents 231.

[0165] By having an air vent 231 on the outer surface of the indoor unit casing 10, and connecting the air vent module 20 to the air vent 231, it is beneficial to distribute the air vent 231 on the indoor unit casing 10, so that the noise of the oxygen airflow discharged from the air vent 231 is smaller and the oxygen is more evenly distributed and discharged into the room. It can also make the air vent 231 for discharging oxygen more visible.

[0166] refer to Figures 11-13 According to some embodiments of this utility model, the air outlet module 20 is located on the outside of the end plate 16. By placing the air outlet module 20 on the outside of the end plate 16, the space occupied by the air outlet module 20 on the inner side of the indoor unit housing 10 can be reduced, thereby reducing the volume of the indoor unit housing 10. When installing or removing the air outlet module 20, it is not necessary to disassemble the indoor unit housing 10, which facilitates the replacement and maintenance of the air outlet module 20.

[0167] refer to Figure 14 An air conditioner according to a second aspect of the present invention includes: an indoor unit 100 and an outdoor unit 200 according to a first aspect of the present invention. The outdoor unit 200 includes an outdoor unit body 30 and an oxygen generator 40. The oxygen generator 40 is installed on the outdoor unit body 30. An air outlet module 20 is connected to an air inlet pipe, which is connected to the oxygen generator 40. The air inlet pipe is used to introduce oxygen generated by the oxygen generator 40 into the air outlet module 20.

[0168] The oxygen generator 40 generates oxygen, which is then fed into the outlet chamber 21 of the outlet module 20 through the inlet pipe, and then discharged into the room through the outlet hole 231.

[0169] In addition, by integrating the oxygen generator 40 with the outdoor unit 30, it is convenient to install and fix the whole unit.

[0170] For example, the air conditioner can be a split-type wall-mounted air conditioner.

[0171] According to the embodiment of the present invention, the air conditioner includes an outdoor unit 200 and an outdoor unit 200 with an oxygen generating device 40. The oxygen generated by the oxygen generating device 40 can be transported to the indoor unit 100 through an oxygen delivery pipeline. The inlet pipe of the oxygen delivery pipeline is connected to the inlet port 22 of the outlet module 20, which facilitates the connection between the oxygen delivery pipeline and the indoor unit 100. By allowing the oxygen to flow from the inlet port 22 of the outlet module 20 to the outlet chamber 21 of the outlet module 20, the outlet chamber 21 can play a role in buffering and reducing the noise of the oxygen. In this way, when the oxygen in the outlet chamber 21 is discharged into the room through the outlet port 231, the noise generated by the oxygen flow into the room can be reduced.

[0172] refer to Figure 14 According to some embodiments of the present invention, the outdoor unit body 30 includes an outdoor unit housing 31 and a heat exchange and exhaust assembly and a compressor assembly disposed in the outdoor unit housing 31. The outdoor unit housing 31 is provided with an outdoor air inlet 33 and an outdoor air outlet 32. An oxygen generator 40 is installed in the outdoor unit housing 31 and is detachably connected to the outdoor unit housing 31.

[0173] For example, the heat exchange and exhaust assembly may include an outdoor heat exchanger and an outdoor fan. Air enters the outdoor unit housing 31 from the outdoor air inlet 33, exchanges heat with the outdoor heat exchanger, and is then exhausted to the outside from the outdoor air outlet 32 ​​under the drive of the outdoor fan.

[0174] For example, the oxygen generator 40 can be installed on the top of the outdoor unit housing 31 or on the side of the outdoor unit housing 31.

[0175] For example, the oxygen generator 40 can be connected to the outdoor unit housing 31 by screws.

[0176] By making the oxygen generator 40 detachably connected to the outdoor unit housing 31, the installation and removal of the oxygen generator 40 are highly flexible, facilitating the maintenance or replacement of the oxygen generator 40.

[0177] refer to Figures 15-16 According to some embodiments of this utility model, the oxygen generator 40 is located on the top of the outdoor unit body 30. By placing the oxygen generator 40 on the top of the outdoor unit body 30, the space at the top of the outdoor unit body 30 can be utilized, reducing the occupation of horizontal space. It also facilitates the installation of the oxygen generator 40 onto the outdoor unit body 30, improving the assembly efficiency of the oxygen generator 40. When the oxygen generator 40 or the outdoor unit body 30 needs maintenance, the efficiency of installation and disassembly of the oxygen generator 40 and the outdoor unit body 30 can also be improved.

[0178] refer to Figures 14-16According to some embodiments of this utility model, the oxygen generating device 40 is installed on the top of the outdoor unit housing 31. The outdoor unit housing 31 has a compressor chamber and a fan chamber arranged in a left-right direction. The compressor chamber and the fan chamber are separated by a partition. The heat exchange exhaust assembly is located in the fan chamber, and the compressor assembly is located in the compressor chamber. The oxygen generating device 40 is located on the top of the outdoor unit housing 31. The oxygen generating device 40 includes a device housing 41 and an oxygen generating assembly 42. The device housing 41 includes a bottom plate 411 and a side plate 412. The oxygen generating assembly 42 is located inside the device housing 41. The bottom plate 411 of the device housing 41 has an air outlet, which is located directly above the fan chamber and connects the receiving cavity inside the device housing 41 with the fan chamber inside the outdoor unit housing 31. The side plate 412 of the device housing 41 has an air inlet.

[0179] When the outdoor unit 200 of the air conditioner is working, the outdoor fan drives outside air to enter the fan cavity from the outdoor air inlet 33, where it exchanges heat with the outdoor heat exchanger and is then discharged from the outdoor air outlet 32. At the same time, since the receiving cavity inside the device housing 41 is connected to the fan cavity through the air outlet, it can also drive outside air to enter the receiving cavity from the air inlet. The air entering the receiving cavity is processed by the oxygen generating component 42, which separates oxygen and delivers it to the indoor unit through the oxygen output pipe.

[0180] refer to Figures 15-16 According to some embodiments of this utility model, the outdoor unit housing 31 includes a housing body 311 and a housing top cover 312. A heat exchange and exhaust assembly and a compressor assembly are disposed within the housing body 311. The housing body 311 has an outdoor air inlet 33 and an outdoor air outlet 32. An oxygen generator 40 is disposed on the top of the housing body 311. The housing top cover 312 covers the top of the side panel 412.

[0181] By placing the oxygen generator 40 on the top of the main body 311, the space at the top of the main body 311 can be utilized, reducing the occupation of horizontal space. This also facilitates the installation of the oxygen generator 40 onto the main body 311, improving the assembly efficiency of the oxygen generator 40.
