Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, specifically to a fresh air module, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] Split-type air conditioners are now widely used in homes. A split-type air conditioner generally consists of an indoor unit and an outdoor unit, which are installed separately indoors and outdoors. The indoor and outdoor units are usually connected by through-wall pipes, which typically include a refrigerant pipe for connecting the refrigerant between the indoor and outdoor units, and a drain pipe for draining the condensate produced by the indoor unit during operation.

[0003] When installing existing air conditioners, it is generally necessary to make a through-wall hole in the wall for the through-wall pipe to pass through. The inner diameter of the through-wall hole and the outer diameter of the through-wall pipe are generally difficult to match perfectly, which can easily create an installation gap at the assembly point and reduce the sealing effect. In order to seal the installation gap, existing technology can use sealing putty or other materials between the through-wall hole and the through-wall pipe. Although this can achieve a certain degree of sealing of the installation gap, it reduces the aesthetics of the wall. Summary of the Invention

[0020] Optionally, the interior of the body forms two sequentially connected cavities, at least one of which is connected to the air inlet section;

[0021] One of the two cavities constitutes the air outlet section, and the other is for the wall-penetrating pipe assembly to pass through.

[0022] Optionally, the two cavities are arranged sequentially in directions approaching and away from the covering surface;

[0023] The cavity near the cover surface is for the through-wall pipe assembly to pass through.

[0024] Optionally, the fresh air duct has a fresh air inlet and a fresh air outlet;

The main body covers the through-wall hole, sealing and concealing the installation gap between the through-wall hole and the through-wall pipe assembly, achieving both sealing and aesthetics during installation. Furthermore, since the through-wall hole connects the indoor and outdoor environments, covering the through-wall hole with the main body and connecting the fresh air duct to it not only facilitates direct access to outdoor fresh air for the fresh air duct, enabling the fresh air module to deliver fresh air, but also allows the main body to be close enough to the through-wall hole, simplifying the structure of at least the air intake section of the fresh air duct. This increases the airflow volume of the fresh air duct and improves the quality of fresh air delivery from the fresh air module. Attached Figure Description

[0059] Split-type air conditioners are now widely used in homes. A split-type air conditioner generally consists of an indoor unit and an outdoor unit, which are installed separately indoors and outdoors. The indoor and outdoor units are usually connected by through-wall pipes, which typically include a refrigerant pipe for connecting the refrigerant between the indoor and outdoor units, and a drain pipe for draining the condensate produced by the indoor unit during operation.

[0060] When installing existing air conditioners, it is generally necessary to make a through-wall hole in the wall for the through-wall pipe to pass through. The inner diameter of the through-wall hole and the outer diameter of the through-wall pipe are generally difficult to match perfectly, which can easily create an installation gap at the assembly point and reduce the sealing effect. In order to seal the installation gap, existing technology can use sealing putty or other materials between the through-wall hole and the through-wall pipe. Although this can achieve a certain degree of sealing of the installation gap, it reduces the aesthetics of the wall.

[0061] In view of the above, the present invention provides a fresh air module applied to an indoor unit of an air conditioner. The indoor unit refers to a device used in an indoor environment for air treatment; the indoor unit can be used in an air conditioner. It is understood that the air conditioner can be a split-type air conditioner, including the indoor unit and an outdoor unit located in the outdoor environment, separated by at least one wall. Of course, the air conditioner can also be other types of air conditioners. All air conditioners or other air purification devices that include an indoor unit operating in an indoor environment and that needs to be connected to the outdoor environment through pipework or other structures are within the scope of protection of this design.

[0062] However, for easier understanding, please refer to Figures 1 to 6 In the following embodiments, the fresh air module is applied to an air conditioner, and the air conditioner includes an indoor unit and an outdoor unit.

[0063] Please see Figures 1 to 3 The fresh air module 20 provided by the present invention includes a body 200 and a wall-penetrating pipe assembly 300. The body 200 forms a fresh air duct 210; the wall-penetrating pipe assembly 300 includes multiple pipes, at least a portion of which are used to connect the indoor unit 1 and the outdoor unit of the air conditioner, and the wall-penetrating pipe assembly 300 is integrally connected to the body 200; the fresh air duct 210 communicates with a wall-penetrating hole 70, and the body 200 is configured to cover the wall-penetrating hole 70.

[0064] In the technical solution provided by this invention, the body 200 and the through-wall hole 70 are integrated, allowing the through-wall hole 70 to be installed directly during the installation of the body 200, which simplifies the installation operation of the entire unit. The body 200 covers the through-wall hole 70, which can seal and block the installation gap between the through-wall hole 70 and the through-wall pipe assembly 300, thus achieving both sealing and aesthetics during the installation of the through-wall pipe assembly 300. In addition, since the through-wall hole 70 connects the indoor and outdoor environments, by covering the through-wall hole 70 with the body 200 and connecting the fresh air duct 210 to the through-wall hole 70, it not only helps the fresh air duct 210 to directly access the outdoor fresh air and realize the fresh air supply function of the fresh air module 20, but also allows the body 200 to be close enough to the through-wall hole 70, which helps to simplify the structure of at least the air inlet section 211 of the fresh air duct 210, thereby increasing the air intake volume of the fresh air duct 210 and improving the fresh air supply quality of the fresh air module 20.

[0065] It is understood that the body 200 includes a shell forming the fresh air duct 210, and the necessary components for realizing the fresh air supply function. The necessary components include, for example, a fan 400 for driving the fresh air to flow in a specified direction and at a specified flow rate, and a power supply component electrically connected to the fan 400 to supply power to the fan 400. The specific form of the necessary components is not limited.

[0066] The housing is provided with a fresh air inlet 213, a fresh air outlet 214, and a fresh air duct 210 connecting the fresh air inlet 213 and the fresh air outlet 214, so that outdoor fresh air enters through the fresh air inlet 213, flows through the fresh air duct 210, and is discharged from the fresh air outlet 214 into the environment inside the hole.

[0067] The fresh air inlet 213 and the fresh air outlet 214 are generally spaced apart. Since the fresh air duct 210 is connected to the wall penetration hole 70, the fresh air inlet 213 can be installed in the indoor environment and directly connected to the wall penetration hole 70, or the fresh air inlet 213 can pass through the wall penetration hole 70 and be installed in the outdoor environment.

[0068] The fresh air outlet 214 is located in the indoor environment and can be located on the top, bottom, or any side of the unit 200. It should be noted that the orientation of the fresh air outlet 214 is related to the overall installation orientation of the fresh air module 20 on the wall 7. For example, when the wall 7 is the ceiling, the fresh air module 20 is essentially installed above the user; in this case, the fresh air outlet 214 can be located at the bottom of the unit 200, allowing the fresh air to blow downwards and towards the user. When the wall 7 is a vertical surface, the fresh air module 20 is essentially installed beside the user; in this case, the fresh air outlet 214 can be located on any surface of the unit 200, allowing the fresh air blown out through the outlet 214 to more efficiently ventilate the indoor environment.

[0069] The fresh air inlet 213 and / or the fresh air outlet 214 can each be configured as one or more. When multiple fresh air inlets 213 and / or fresh air outlets 214 are configured, taking the fresh air outlet 214 as an example, the multiple fresh air outlets 214 can be arranged on the same side surface of the body 200, or they can be arranged on different side surfaces of the body 200. Furthermore, the arrangement of the multiple fresh air outlets 214 is not limited; they can be distributed, arranged in an array, arranged radially, or arranged in other ways.

[0070] In addition, the fresh air module 20 also includes an air guide structure 240, which can be set at the fresh air inlet 213 and / or the fresh air outlet 214. Taking the air guide structure 240 set at the fresh air inlet 213 as an example, the air guide structure 240 can be an air guide grille, a flip-up air guide plate, etc.

[0071] The body 200 has a cover surface 221, which is configured to abut against the wall surface surrounding the through-wall hole 70 to cover the through-wall hole 70 when the body 200 is installed to the wall 7 via the through-wall pipe assembly 300. Therefore, in one embodiment, the shape of the cover surface 221 is adapted to the shape of the wall surface surrounding the through-wall hole 70 at the corresponding position, so that the cover surface 221 can fully fit against the wall surface.

[0072] Of course, in a further embodiment, the body 200 may have a sealing gasket layer at least at the cover surface 221, or the material at least at the cover surface 221 may be an elastic material. Thus, when the fresh air module 20 is installed on the wall 7, the sealing gasket layer or its own elastic material on the cover surface 221 can undergo elastic deformation under pressure, thereby better abutting against the wall surface around the through-hole 70, achieving a better sealing effect.

[0073] In one embodiment, the through-wall pipe assembly 300 and the fresh air duct 210 are arranged side by side. That is, the wiring direction of the through-wall pipe assembly 300 is approximately the same as the extension direction of the fresh air duct 210 at the corresponding position. When the body 200 includes a duct shell 201 forming the fresh air duct 210, the above arrangement allows the through-wall pipe assembly 300 and the duct shell 201 to be closely connected and substantially integrated, thereby making the shape and size of the through-wall hole 70 controllable. This helps to ensure that the inner diameter of the through-wall hole 70 is sufficiently close to the overall size of the through-wall pipe assembly 300 and the duct shell 201, thereby reducing or eliminating the installation gap between the fresh air module 20 and the through-wall hole 70.

[0074] It should be noted that the connection between the through-wall pipe assembly 300 and the air duct housing 201 can be a close abutment or a fixed connection. In one embodiment, the through-wall pipe assembly 300 can be disposed outside the fresh air duct 210. Based on this, the through-wall pipe assembly 300 can be entirely exposed outside the body 200, or the body 200 can also include a mounting shell disposed on one side of the air duct housing 201, the mounting shell forming a wiring channel extending parallel to the fresh air duct 210, the wiring channel for the through-wall pipe assembly 300 to pass through for wiring, thereby both limiting the wiring position and direction of the through-wall pipe assembly 300 and protecting the wiring of the through-wall pipe assembly 300.

[0075] In another embodiment, the through-wall pipe assembly 300 can be disposed inside the fresh air duct 210. Specifically, the through-wall pipe assembly 300 is at least partially disposed within the fresh air duct 210. That is, the fresh air duct 210 can fulfill both its fresh air supply function and its wiring duct function. It can be understood that the cross-sectional area of ​​the fresh air duct 210 is larger than the overall outer diameter of the through-wall pipe assembly 300, so that sufficient space is reserved between the through-wall pipe assembly 300 and the inner wall of the fresh air duct 210 for fresh air circulation. In addition, the section of the through-wall pipe assembly 300 that is at least disposed within the fresh air duct 210 needs to be designed with a uniform surface shape and smooth texture as much as possible to help reduce air resistance to fresh air.

[0076] It should be noted that the through-wall pipe assembly 300 is at least partially installed within the fresh air duct 210. It can be a section of the through-wall pipe assembly 300 along its length or a portion of the pipe body along its radial direction. For example, when the through-wall pipe assembly 300 includes a refrigerant pipe 310 and a drain pipe 320, the refrigerant pipe 310 can be housed within the fresh air duct 210 and the drain pipe 320 can be housed outside the fresh air duct 210; this is not a limitation.

[0077] When, as described above, the body 200 includes a duct shell 201 forming the fresh air duct 210, the through-wall pipe assembly 300 includes a refrigerant pipe 310 and a drain pipe 320. The refrigerant pipe 310 and the drain pipe 320 can be jointly and directly housed within the fresh air duct 210.

[0078] Alternatively, in one embodiment, the refrigerant pipe 310 is at least partially inserted into the fresh air duct 210, and the drain pipe 320 is disposed in the duct shell 201 and spaced apart from the fresh air duct 210.

[0079] It can be understood that the refrigerant pipe 310 is also the pipe for the flow of refrigerant. The refrigerant pipe 310 generally connects the indoor unit 1 and the outdoor unit of the air conditioner, forming a component in the refrigeration circuit of the air conditioner; the drain pipe 320 generally connects at least to the indoor unit 1 of the air conditioner, and is used to lead the condensate generated and collected during the normal operation of the indoor unit 1 to the outdoor environment. It needs to pass through the wall hole 70, but it is not necessarily connected to the outdoor unit of the air conditioner.

[0080] Thus, the refrigerant pipe 310 and the drain pipe 320 may have different laying directions, and there may be a temperature difference between the outer surfaces of the refrigerant pipe 310 and the drain pipe 320. By setting the refrigerant pipe 310 inside the fresh air duct 210 and setting the drain pipe 320 to be separated from the fresh air duct 210, the refrigerant pipe 310 and the drain pipe 320 are close enough but independent of each other. This is beneficial to the overall installation and wiring of the through-wall pipe assembly 300, and also helps to avoid mutual interference between the refrigerant pipe 310 and the drain pipe 320.

[0081] Specifically, please refer to Figure 5 In one embodiment, the drain pipe 320 is at least partially embedded in one side wall of the duct housing 201. The side wall of the duct housing 201 adjacent to the fresh air duct 210 may be configured to have a thicker wall and may have a through hole along its length, the through hole for the drain pipe 320 to pass through for wiring, or the through hole directly constitutes at least a section of the drain pipe 320.

[0082] Please see Figure 6 In another embodiment, the body 200 further includes a partition 202 disposed within the inner cavity of the air duct shell 201 to divide the inner cavity of the air duct shell 201 into two independent chambers, which extend side by side. One of the two chambers constitutes the fresh air duct 210, while the other is through which the drain pipe 320 passes.

[0083] The orientation of the two chambers is not limited. In one embodiment, the two chambers can be arranged sequentially in a vertical direction, with the upper chamber forming the fresh air duct 210 and the lower chamber through which the water supply and drainage pipes 320 pass. This allows the condensate to fall onto the partition 202 even when the refrigerant pipe 310 condenses on its outer surface due to the temperature difference between the indoor and outdoor environments. Furthermore, the partition 202 can be arranged to gradually slope downwards from the indoor to the outdoor direction, forming a certain inclined guide surface to drain the condensate from the refrigerant pipe 310 outwards.

[0084] The partition 202 can separate the installation space of the fresh air duct 210 and the drain pipe 320. Of course, the partition 202 can also be used to support the installation of the refrigerant pipe 310 and the drain pipe 320.

[0085] In view of the above, this design does not limit the specific form of the body 200. Please refer to [link / reference]. Figure 4In one embodiment, the body 200 includes a main body 220 and a protruding post 230 extending from one side of the main body 220. The fresh air duct 210 is disposed through the protruding post 230 and the main body 220. The side surface on the main body 220 on which the protruding post 230 is formed is a covering surface 221, which is used to cover the through-wall hole 70. The protruding post 230 is used to insert and connect to the through-wall hole 70.

[0086] The body 220 can be plate-shaped or block-shaped. The area of ​​the cover surface 221 is larger than the cross-sectional area of ​​the protrusion 230, so that when the protrusion 230 is inserted into the through-wall hole 70, the cover surface 221 can abut against the peripheral wall of the through-wall hole 70, and cover and seal the installation gap between the through-wall hole 70 and the protrusion 230. The specific setting of the cover surface 221 can be referred to the above. The shape of the protrusion 230 is adapted to the inner shape of the through-wall hole 70. The length of the protrusion 230 is not limited, and can be set to be the same as, slightly smaller than, or slightly larger than the length of the through-wall hole 70, depending on actual needs. Thus, when the protruding post 230 is inserted into the through-wall hole 70, the through-wall hole 70 can restrict some degrees of freedom of the fresh air module 20. Combined with other methods of installation and fixation between the fresh air module 20 and the wall 7, the installation stability between the fresh air module 20 and the wall 7 can be strengthened. Of course, the setting of the protruding post 230 also helps to ensure the cleanliness of the fresh air entering the fresh air duct 210, and avoids the environment inside the through-wall hole 70 from contaminating the incoming fresh air and reducing the quality of the fresh air.

[0087] The installation method between the unit 200 and the wall 7 is not limited. The fresh air module 20 can be screwed to the wall by inserting the protruding post 230 into the through hole 70 and abutting the cover surface 221 against the wall surface around the through hole 70, or the fresh air module 20 can be hung or fastened to the wall by hooks, buckles or other structures, or the fresh air module 20 can be glued to the wall by adhesive, or the fresh air module 20 can be magnetically attached to the iron area of ​​the wall by magnetic sheets, etc.

[0088] As described above, the fresh air duct 210 is configured to penetrate the protruding post 230 and the main body 220, allowing for the installation of a fresh air duct 210 of the required length and width within the limited space of the main body 200, thereby ensuring that the required fresh air volume is met. Specifically, please refer to... Figures 1 to 3In one embodiment, the fresh air duct 210 includes an air inlet section 211 disposed on the protruding post 230 and an air outlet section 212 disposed on the body 220; the fresh air module 20 further includes a fan 400 disposed on the air outlet section 212.

[0089] It should be noted that the naming of the air inlet section 211 and the air outlet section 212 is only used to distinguish between the two air duct sections of the fresh air duct 210, one located on the protruding post 230 and the other on the main body 220, and does not constitute a limitation on the function of the two air duct sections. The fresh air inlet 213 is located at the air inlet section 211, and the fresh air outlet 214 is located at the air outlet section 212.

[0090] The fan 400 guides fresh outdoor air into the room through the fresh air inlet 213, which then flows sequentially through the air inlet section 211 and the air outlet section 212 before being discharged into the indoor environment through the fresh air outlet 214. Positioning the fan 400 at the air outlet section 212 helps to eliminate the influence of the overall size of the fan 400 on the size of the protruding column 230, preventing the fan 400 from increasing the size of the protruding column 230 and consequently the size of the wall penetration hole 70, thus avoiding structural waste in the wall 7. Furthermore, it helps to increase the airflow intensity at the air outlet section 212, ensuring that the fresh air discharged into the indoor environment is driven to the desired area, achieving a better fresh air delivery effect.

[0091] As described above, when the through-wall duct assembly 300 is at least partially installed within the fresh air duct 210, the interior of the main body 220 forms two sequentially connected cavities, at least one of which is connected to the air inlet section 211; one of the two cavities constitutes the air outlet section 212, and the other is for the through-wall duct assembly 300 to pass through. That is, in this embodiment, the through-wall duct assembly 300 can be separated from the air outlet section 212, so that the fresh air outlet and the through-wall duct assembly 300 do not interfere with each other. This reduces the impact of the through-wall duct assembly 300 on the fresh air outlet, for example, by preventing the through-wall duct assembly 300 from increasing the air resistance of the fresh air outlet or disrupting the direction of the fresh air outlet.

[0092] Furthermore, in one embodiment, the two cavities can be arranged sequentially in directions approaching and away from the covering surface 221; wherein the cavity approaching the covering surface 221 is for the through-wall pipe assembly 300 to pass through. That is, the two cavities are arranged sequentially in directions approaching and away from their respective locations. When the cavity approaching the covering surface 221 is provided for the through-wall pipe assembly 300 to pass through, the fresh air outlet is positioned as close as possible to the central area of ​​the indoor environment, i.e., close enough to the user. At the same time, the through-wall pipe assembly 300 is routed close to the wall, which helps to ensure the wiring of the through-wall pipe assembly 300 is stable and neat, and also improves the aesthetics of the wiring.

[0093] In one embodiment, the fresh air duct 210 has a fresh air inlet 213 and a fresh air outlet 214. The fresh air inlet 213 is located at the end of the protrusion 230 away from the main body 220, and the fresh air outlet 214 is located on the side of the main body 220. The fresh air inlet 213 is located at the end of the protrusion 230 away from the main body 220, that is, at the outermost end of the unit 200, which helps to fully access outdoor fresh air. The fresh air outlet 214 is located on the side of the main body 220, so that the fresh air entering the room will not blow directly towards the user, but will circulate laterally and then flow towards the central area, which helps to improve the user's physical comfort when the fresh air is delivered. In addition, it can promote a larger circulation between outdoor fresh air and indoor air, and can exchange air in a larger area of ​​the room.

[0094] Furthermore, based on any of the above embodiments, the fresh air module 20 further includes a purification component 500 disposed within the fresh air duct 210; the purification component 500 is detachably connected to the body 200. The purification component 500 can be a filter component used to filter out impurities carried in the passing fresh air. The specific type of filter component is not limited; for example, it can be a formaldehyde removal filter, a HEPA (High Efficiency Particulate Air) filter, an activated carbon filter, a filter paper filter, etc. The purification component 500 can also be an ultraviolet light generator, etc. Of course, the purification component 500 can also be an active purification device, such as a purification molecule generated through electrolysis or other reactions and actively dispersed within the fresh air duct 210.

[0095] The placement of the purification component 500 within the fresh air duct 210 is not limited; it can be placed at any location within the duct, such as at the air inlet section 211, the air outlet section 212, or the connection point between the air inlet section 211 and the air outlet section 212. In one embodiment, the purification component 500 can be placed on the air inlet side of the fan 400, allowing purified fresh air to pass through the fan 400, thus preventing unpurified fresh air from contaminating or damaging the fan 400.

[0096] Specifically, in one embodiment, the side wall of the fresh air duct 210 is provided with an opening communicating with the outer wall of the body 200; the purification component 500 is inserted into the fresh air duct 210 through the opening, facilitating the disassembly and replacement of the purification component 500. When the purification component 500 is inserted into the fresh air duct 210, at least the outer end of the purification component 500 is adapted to the size and shape of the opening, exposed outside the body 200, and covering the opening; or, the body 200 further includes a cover movably installed in the opening, the cover being movable to open and close the opening, so that when the opening is closed, the purification component 500 is protected within the fresh air duct 210.

[0097] Furthermore, based on any of the above embodiments, the fresh air module 20 also includes a temperature regulating device 600, which is disposed in the fresh air duct 210. The temperature regulating device 600 is used to adjust the temperature of the fresh air passing through the fresh air duct 210, so that the temperature of the fresh air discharged into the indoor environment is more suitable. The temperature regulating device 600 can be used to regulate the rise and fall of the fresh air temperature. For example, when the indoor unit 1 of the air conditioner cools the indoor environment and the indoor temperature is lower than the outdoor temperature, the temperature regulating device 600 can cool the fresh air passing through the fresh air duct 210, so that the temperature of the fresh air discharged into the room is closer to the cooling temperature; conversely, when the indoor unit 1 of the air conditioner heats the indoor environment and the indoor temperature is higher than the outdoor temperature, the temperature regulating device 600 can heat the fresh air passing through the fresh air duct 210, so that the temperature of the fresh air discharged into the room is closer to the heating temperature.

[0098] The temperature control device 600 may include a heating unit and a cooling unit. The heating unit and the cooling unit may be set up separately and work independently, or the heating unit and the cooling unit may be integrated into one unit.

[0099] In a further embodiment, the temperature control device 600 includes a temperature control plate 610, which is housed within the fresh air duct 210 along with at least a portion of the through-wall pipe assembly 300. It is understood that the plate-shaped temperature control plate 610 reduces the space occupied by the fresh air duct 210 and is easier to install.

[0100] Based on this, in one embodiment, the temperature regulating plate 610 extends along the radial direction of the fresh air duct 210, that is, the direction of the air passage section. The temperature regulating plate 610 is provided with an air passage hole along the air supply direction, or the temperature regulating plate 610 and at least one side of the air duct wall of the fresh air duct 210 are alternated to make way for the fresh air passage.

[0101] Next, the through-wall pipe assembly 300 passes through the temperature regulating plate 610 and is fixedly connected to the temperature regulating plate 610. In this way, the temperature regulating plate 610 can enhance the installation stability of the through-wall pipe assembly 300 to a certain extent and limit the lateral movement of the through-wall pipe assembly 300 relative to the inner wall of the fresh air duct 210.

[0102] And / or, multiple temperature-regulating fins 610 are spaced apart along the air supply direction. This ensures that the fresh air flowing through each section of the fresh air duct 210 can be temperature-regulated and kept within a suitable temperature range. The power parameters of the multiple temperature-regulating fins 610 can be set to be the same or at least partially different. For example, the power of the multiple temperature-regulating fins 610 can be set to gradually increase, gradually decrease, or alternately increase and decrease from the outside to the inside.

[0103] Furthermore, the present invention also provides an air conditioner indoor unit 1, which includes a main body 10 and a fresh air module 20 as described above. It should be noted that the detailed structure of the fresh air module 20 within the air conditioner indoor unit 1 can be referred to the embodiments of the fresh air module 20 described above, and will not be repeated here.

[0104] At least a portion of the through-wall pipe assembly 300 is used to connect the main body 10 and the outdoor unit of the air conditioner.

[0105] It should be noted that when the through-wall hole 70 is located near the main body 10, the fresh air module 20 can be installed inside the main body 10, but at least the cover surface 221 and the fresh air inlet 213 are exposed outside the main body 10, so that at least the fresh air inlet 213 can be directly connected to the through-wall hole 70 and the cover surface 221 can be directly covered at the through-wall hole 70.

[0106] When the relative position between the main body 10 and the through-wall hole 70 is uncertain, in one embodiment, the fresh air module 20 is separately disposed outside the main body 10. In this way, the installation of the fresh air module 20 and the installation of the main body 10 can be carried out independently, and there are no restrictions on the location of the through-wall hole 70 or the installation location of the main body 10, thus possessing versatility.

[0107] Furthermore, the present invention also provides an air conditioner, which includes an indoor unit 1 and an outdoor unit as described above. It should be noted that the detailed structure of the indoor unit 1 within the air conditioner can be referred to in the embodiments of the indoor unit 1 described above, and will not be repeated here.
