Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] In related technologies, air conditioner indoor units with fresh air exchange functions typically install the fresh air module inside the air conditioner. To achieve top-mounted airflow, the fresh air outlet of the module is usually located at the top, with a corresponding opening at the top of the air conditioner. However, this exposes the fresh air outlet, allowing dust to easily fall into the module's ductwork when the unit is off, thus affecting its lifespan. Furthermore, when the module is operational, dust can flow into the room with the fresh airflow, severely impacting indoor air quality.

[0003] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to propose an indoor air conditioning unit that addresses the technical problem of dust accumulation at the fresh air outlet of a fresh air module in the prior art.

[0013] In one embodiment, the rolling assembly includes a mounting plate and a ball bearing. The mounting plate extends along the height direction of the housing and is mounted on the inner wall surface of the housing. The ball bearing is embedded in the mounting plate, and the air outlet engages with the ball bearing in a rolling manner.

[0017] In one embodiment, the fresh air module further includes a damping mechanism that connects the air outlet to the housing to reduce the vibration of the air outlet.

[0018] In one embodiment, the damping mechanism includes a damping sleeve and a telescopic rod assembly. The damping sleeve is mounted on the housing, and the telescopic rod assembly is disposed inside the damping sleeve and connected to the air outlet.

[0019] In one embodiment, the telescopic rod assembly includes a first spring and a first telescopic rod. The first spring is disposed inside the damping sleeve, one end of the first telescopic rod is disposed inside the damping sleeve and connected to the first spring, and the other end is connected to the air outlet.

[0020] In one embodiment, the telescopic rod assembly further includes a second spring and a second telescopic rod. The second spring is disposed inside the damping sleeve, and one end of the second telescopic rod is disposed inside the damping sleeve and connected to the second spring. The interior of the second telescopic rod is hollow and one end is open. The first spring is disposed inside the second telescopic rod, and one end of the first telescopic rod is disposed inside the second telescopic rod, while the other end is connected to the air outlet.

[0021] In one embodiment, the fresh air module further includes a fan wheel assembly disposed within the air outlet cavity.

[0024] A fresh air module is disposed within the receiving cavity. The fresh air module includes a housing and an air outlet. The housing has an air inlet cavity, and the air outlet has an air outlet cavity communicating with the air inlet cavity and a fresh air outlet communicating with the air outlet cavity. The air outlet is retractable relative to the housing and has an air outlet position extending out of the receiving cavity and a retracted position retracting into the receiving cavity.

When the air outlet is in the retracted position, the air outlet retracts into the receiving cavity, and the casing blocks the fresh air outlet. This prevents dust from falling into the fresh air module from the fresh air outlet, thus avoiding frequent cleaning and replacement of the fresh air module and extending its service life. Simultaneously, the fresh air module has low duct resistance, increasing the fresh air volume and improving the fresh air exchange effect. Attached Figure Description

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] This invention proposes an indoor unit for an air conditioner.

[0052] Please see Figures 1 to 4The present invention proposes an air conditioner indoor unit 100, which includes a housing 110 and a fresh air module 120. The housing 110 has a receiving cavity and an opening 111 communicating with the receiving cavity; the fresh air module 120 is disposed in the receiving cavity, the fresh air module 120 includes a housing 130 and an air outlet 140, the housing 130 has an air inlet cavity 131, the air outlet 140 has an air outlet cavity 142 communicating with the air inlet cavity 131, and a fresh air outlet 141 communicating with the air outlet cavity 142; the air outlet 140 is retractable relative to the housing 110, and has an air outlet position extending out of the receiving cavity and a retracted position retracting into the receiving cavity; when the air outlet 140 is in the air outlet position, the fresh air outlet 141 is exposed outside the housing 110, and when the air outlet 140 is in the retracted position, the housing 110 can block the fresh air outlet 141.

[0053] In this embodiment of the invention, the air conditioner indoor unit 100 specifically relates to a wall-mounted air conditioner indoor unit 100, but is not limited thereto. The air conditioner indoor unit 100 can also be a floor-standing air conditioner indoor unit 100 or a portable air conditioner, etc., without specific limitation. The following will describe the wall-mounted air conditioner indoor unit 100 as an example. The structure of the wall-mounted air conditioner indoor unit 100 can refer to the structure of existing wall-mounted air conditioner indoor units 100, and will not be described in detail here. The casing 110 of the wall-mounted air conditioner indoor unit 100 is provided with a receiving cavity for the installation of the fresh air module 120. The casing 110 is also provided with an opening 111 communicating with the receiving cavity, so that the air outlet 140 of the fresh air module 120 can extend out of the receiving cavity from the opening 111 and retract back into the receiving cavity from the opening 111. The opening 111 can be provided on the top or side of the casing 110 (e.g., front, rear, left or right side), without specific limitation. The size of the opening 111 can be adapted to the size of the air outlet 140, so as to prevent dust and other objects from falling into the housing 110 from the opening 111.

[0054] Please refer to the following: Figures 5 to 8The fresh air module 120 includes a housing 130 and an air outlet 140. The housing 130 has an air inlet cavity 131 and a fresh air inlet 132 communicating with the air inlet cavity 131. The air outlet 140 has an air outlet cavity 142 and a fresh air outlet 141 communicating with the air outlet cavity 142, wherein the air outlet cavity 142 is connected to the air inlet cavity 131. Here, the air inlet cavity 131 and the air outlet cavity 142 together form the fresh air duct of the fresh air module 120. Outdoor fresh air can enter the air inlet cavity 131 from the fresh air inlet 132, then further flow into the air outlet cavity 142, and finally flow into the room from the fresh air outlet 141. The fresh air module 120 has low duct resistance, increasing the fresh air output volume and thus improving the fresh air exchange effect. The positions of the fresh air inlet 132 and the fresh air outlet 141 can be varied. For example, the fresh air inlet 132 can be located at the bottom or side of the housing 130, and the fresh air outlet 141 can be located at the top or side of the air outlet 140. No specific limitation is made.

[0055] In this embodiment of the invention, the housing 130 is fixedly installed within the receiving cavity, and the air outlet 140 is retractable relative to the housing 110 and has an air outlet position and a storage position. Specifically, as... Figure 3 and Figure 4 As shown, when the air outlet 140 is in the air outlet position, the air outlet 140 extends outside the housing 110, and the fresh air outlet 141 is exposed outside the housing 110, so that the fresh air outlet 141 can supply fresh air to the room. Figure 1 and Figure 2 As shown, when the air outlet 140 is in the retracted position, the air outlet 140 retracts into the housing 110, and the housing 110 blocks the fresh air outlet 141. This prevents dust from falling into the fresh air module 120 from the fresh air outlet 141, thereby avoiding frequent cleaning and replacement of the fresh air module 120 and extending its service life.

[0056] There are several ways in which the air outlet 140 can be extended or retracted relative to the housing 110. For example, the air outlet 140 can be a telescopic structure, allowing it to extend and retract, thus extending outside the housing 110 and retracting inside. The telescopic structure can be a telescopic cylinder structure or a bellows structure; there is no specific limitation, as long as it can extend and retract. Another example is that the air outlet 140 can be movable relative to the housing 110, allowing it to extend (move out) from the housing 110 and retract (move back) inside. Again, there are no specific limitations here, and a detailed description will follow.

[0057] The indoor unit 100 of the air conditioner of the present invention includes a housing 110 and a fresh air module 120. The housing 110 has a receiving cavity and an opening 111 communicating with the receiving cavity. The fresh air module 120 includes a housing 130 and an air outlet 140. The housing 130 is provided with an air inlet cavity 131, and the air outlet 140 is provided with an air outlet cavity 142 communicating with the air inlet cavity 131 and a fresh air outlet 141 communicating with the air outlet cavity 142. The air outlet 140 is retractable relative to the housing 110 and has an air outlet position extending out of the receiving cavity and a retractable position within the receiving cavity. The air outlet 141 is exposed outside the housing 110 when the air outlet 140 is in the outlet position, allowing it to supply fresh air into the room. When the air outlet 140 is in the retracted position, it retracts into the housing 110, and the housing 110 covers the fresh air outlet 141. This prevents dust from falling into the fresh air module 120 from the outlet 141, thus avoiding frequent cleaning and replacement of the fresh air module 120 and extending its service life. Simultaneously, the fresh air module 120 has low duct resistance, increasing the fresh air volume and improving the ventilation effect.

[0058] In this embodiment of the invention, the air outlet 140 and the housing 130 can be movably connected, allowing the air outlet 140 to move relative to the housing 130, thereby enabling switching between an air outlet position and a storage position. Alternatively, the air outlet 140 and the housing 130 can be fixedly connected, allowing the air outlet 140 to extend and retract, also enabling switching between an air outlet position and a storage position.

[0059] Please see Figures 1 to 4 In one embodiment, the housing 130 is provided with an installation port communicating with the air inlet cavity 131, and the air outlet 140 is installed at the installation port and is movable relative to the housing 130.

[0060] The air outlet 140 can move vertically relative to the housing 130. Correspondingly, to facilitate the air outlet 140 extending beyond the housing 110, the opening 111 can be located at the top of the housing 110. Alternatively, the air outlet 140 can also move horizontally relative to the housing 130. Correspondingly, to facilitate the air outlet 140 extending beyond the housing 110, the opening 111 can be located on the side of the housing 110. The design can be selected and modified according to actual usage needs, and no specific limitations are made here. The mounting port can be an open opening formed on the housing 130, or a through opening formed on the housing 130, and no specific limitations are made here.

[0061] Please see Figures 1 to 4 In one embodiment, the opening 111 is located at the top of the housing 110, and the fresh air outlet 141 is located at the front of the air outlet 140. When the indoor unit 100 of the air conditioner is in fresh air mode, the air outlet 140 can extend outside the housing 110, and the fresh air outlet 141 can be exposed outside the housing 110, thus achieving forward airflow. When the indoor unit 100 of the air conditioner is in fresh air mode, the air outlet 140 can be moved back into the housing 110, and the housing 110 can cover the fresh air outlet 141, thus preventing dust from falling into the interior of the fresh air module 120 from the fresh air outlet 141. In this way, the airflow resistance of the fresh air module 120 is effectively reduced, thereby reducing the loss of fresh air volume, increasing the fresh air output volume, and improving the fresh air exchange effect.

[0062] Please see Figure 1 and Figure 2 In this embodiment, when the air outlet 140 is in the retracted position, the air outlet 140 can be flush with the housing 110. Specifically, the top surface of the air outlet 140 can be flush with the top surface of the housing 110. This ensures a consistent overall appearance of the indoor air conditioning unit 100 and improves the visual effect.

[0063] Considering that an air outlet grille is provided at the fresh air outlet 141, in order to avoid the air outlet grille, in one embodiment, an avoidance notch 133 can be opened on the housing 130. When the air outlet 140 is in the retracted position, the air outlet 140 can be moved into the air inlet cavity 131 of the housing 130, and the air outlet grille is located within the avoidance notch 133 (e.g., Figure 5 and Figure 7 (As shown). This reduces the volume of the housing 130, thereby reducing the overall volume of the fresh air module 120, and consequently, the fresh air module 120 occupies less internal space in the air conditioning indoor unit 100. Of course, in other embodiments, the avoidance notch 133 may not be provided on the housing 130.

[0064] It should be noted that regardless of whether the air outlet 140 is in the retracted position or the air outlet position, the air outlet cavity 142 and the air inlet cavity 131 are always in communication. There are several ways in which the air outlet cavity 142 and the air inlet cavity 131 of the air outlet 140 can be connected, which will be described in detail below.

[0065] Please see Figure 16 and Figure 17In one embodiment, the air outlet cavity 142 includes a first sub-cavity 143 and a second sub-cavity 144 that are interconnected, the air inlet cavity 131 is connected to the first sub-cavity 143, and the fresh air outlet 141 is connected to the second sub-cavity 144.

[0066] In this embodiment, outdoor fresh air enters the air inlet cavity 131 through the fresh air inlet 132, flows into the first sub-cavity 143 from the air inlet cavity 131, then flows into the second sub-cavity 144 from the first sub-cavity 143, and finally flows out from the fresh air outlet 141. Optionally, the first sub-cavity 143 and the second sub-cavity 144 can be arranged along the width direction of the air outlet 140. In this way, the airflow resistance of the fresh air module 120 is reduced, the fresh air output volume is increased, and the fresh air exchange effect is improved. At the same time, the internal space of the air conditioner indoor unit 100 is made more efficient, making the internal structure of the air conditioner indoor unit 100 more compact.

[0067] Of course, in other embodiments, the air outlet cavity 142 can also be a large air cavity, in which case the air outlet cavity 142 is directly connected to the air inlet cavity 131, and no specific limitation is made here.

[0068] Please see Figures 5 to 8 In one embodiment, the outer wall surface of the air outlet 140 is slidably engaged with the inner wall surface of the housing 130. That is, the housing 130 is fitted over the air outlet 140. This facilitates movement of the air outlet 140 relative to the housing 130 and improves the overall sealing of the fresh air module 120, ensuring that the fresh airflow entering the air inlet cavity 131 of the housing 130 can enter the air outlet cavity 142 of the air outlet 140, thereby increasing the fresh air volume and improving the fresh air exchange effect. Alternatively, in another embodiment, the inner wall surface of the air outlet 140 may slidably engage with the outer wall surface of the housing 130. That is, the air outlet 140 is fitted over the housing 130; this is not specifically limited here.

[0069] Further, please refer to Figure 4 To reduce the sliding resistance of the air outlet 140, a rolling assembly 150 can be provided between the air outlet 140 and the housing 130. By providing the rolling assembly 150 between the air outlet 140 and the housing 130, the sliding friction between the air outlet 140 and the housing 130 can be effectively reduced, making it easier for the air outlet 140 to move between the air outlet position and the storage position.

[0070] The structure of the rolling assembly 150 can vary; for example, it may include a roller assembly or a ball bearing assembly. The rolling assembly 150 can be mounted on the outer wall of the air outlet 140 or on the inner wall of the housing 130, depending on the specific application. Please refer to [link / reference]. Figure 6 , Figure 8 , Figure 16 and Figure 17 In one embodiment, the rolling assembly 150 includes a mounting plate 151 and ball bearings 152. The mounting plate 151 extends along the height direction of the housing 130 and is mounted on the inner wall surface of the housing 130. The ball bearings 152 are embedded in the mounting plate 151, and the air outlet 140 rolls in cooperation with the ball bearings 152. Thus, the ball bearings 152 roll in cooperation with the outer surface of the air outlet 140, thereby reducing the sliding friction between the air outlet 140 and the housing 130, and consequently reducing the sliding resistance of the air outlet 140.

[0071] To further reduce the sliding resistance of the air outlet 140, multiple rolling components 150 can be provided, and the multiple rolling components 150 are arranged at intervals along the circumferential direction of the housing 130. Each rolling component 150 may include multiple balls 152, and the multiple balls 152 are arranged at intervals along the length direction of the mounting plate 151.

[0072] Please see Figure 6 and Figure 8 In the above embodiments, to facilitate control of the movement of the air outlet 140, the fresh air module 120 further includes a drive mechanism 160, which drives the air outlet 140 to move between the storage position and the air outlet position. The structure of the drive mechanism 160 can vary; for example, it may include a motor 192 or a cylinder. The drive mechanism 160 can directly drive the air outlet 140 to move, or it can indirectly drive the air outlet 140 to move via a telescopic mechanism 170.

[0073] Please see Figure 4 , Figure 6 and Figure 8 In one embodiment, the fresh air module 120 further includes a telescopic mechanism 170, which is connected to the air outlet 140. The drive mechanism 160 drives the air outlet 140 to move through the telescopic mechanism 170. The structure of the telescopic mechanism 170 can also vary, and will be described in detail below.

[0074] Please see Figures 9 to 15In one embodiment, the telescopic mechanism 170 includes a worm gear 171, a transmission rod 172, and a rotating push rod 174. The drive mechanism 160 is drivenly connected to the worm gear 171. The outer periphery of the transmission rod 172 is provided with a worm wheel 173 that cooperates with the worm gear 171. The interior of the transmission rod 172 is hollow. The rotating push rod 174 is installed inside the transmission rod 172 and is threadedly engaged with the transmission rod 172. The air outlet 140 is connected to the rotating push rod 174.

[0075] The worm gear 171 extends horizontally, while the transmission rod 172 and the rotating push rod 174 both extend vertically. The worm wheel 173 is located at the lower end of the transmission rod 172. When the drive mechanism 160 drives the worm gear 171 to rotate, the worm gear 171 meshes with the worm wheel 173 on the transmission rod 172, causing the transmission rod 172 to rotate. The transmission rod 172 and the rotating push rod 174 are threaded together, thereby causing the rotating push rod 174 to move vertically. This converts the rotational torque of the drive mechanism 160 into linear motion of the air outlet 140 in the vertical direction.

[0076] In this embodiment, the worm gear 173 and the transmission rod 172 can be integrally formed or separately, without specific limitation. The meshing between the worm gear 171 and the transmission rod 172, and the threaded transmission between the transmission rod 172 and the rotating push rod 174, both have a self-locking function. It should be noted that in this embodiment, by using the telescopic mechanism 170 composed of the worm gear 171, the transmission rod 172, and the rotating push rod 174, the air outlet 140 can be ensured to move vertically, thereby switching the air outlet 140 between the air outlet position and the retracted position. At the same time, the two-stage self-locking function between the worm gear 171 and the transmission rod 172, and between the transmission rod 172 and the rotating push rod 174, effectively supports the air outlet 140, ensuring that the air outlet 140 maintains normal operation during movement, resulting in high reliability.

[0077] In this embodiment, the telescopic mechanism 170 further includes a mounting cylinder 175, which is mounted on the housing 130. The transmission rod 172 is partially mounted within the mounting cylinder 175, and the worm gear 171 extends into the mounting cylinder 175 and meshes with the worm wheel 173. By providing the mounting cylinder 175, the transmission rod 172 can be protected to a certain extent, and the installation of the transmission rod 172 is also facilitated. Of course, in other embodiments, the mounting cylinder 175 may not be provided, and no specific limitation is made here.

[0078] In another embodiment, the telescopic mechanism 170 includes a transmission gear and a rack plate meshing with the transmission gear. The drive mechanism 160 is drivenly connected to the transmission gear, the rack plate meshes with the transmission gear, and the air outlet 140 is connected to the rack plate. When the drive mechanism 160 drives the transmission gear to rotate, the transmission gear will drive the rack plate to move, thereby driving the air outlet 140 to move. The rack plate can extend vertically.

[0079] Additionally, please see Figures 9 to 12 In one embodiment, the fresh air module 120 further includes a damping mechanism 180, which connects the air outlet 140 and the housing 130 to reduce the vibration of the air outlet 140.

[0080] It is worth mentioning that by setting the damping mechanism 180, on the one hand, the vibration generated by the air outlet 140 during operation can be effectively reduced, and the noise can be reduced; on the other hand, it can also support the air outlet 140, ensuring that the air outlet 140 maintains normal operation during movement.

[0081] There are various structures for the damping mechanism 180. For example, in one embodiment, the damping mechanism 180 includes a damping sleeve 181 and a telescopic rod assembly. The damping sleeve 181 is mounted on the housing 130, and the telescopic rod assembly is disposed inside the damping sleeve 181 and connected to the air outlet 140.

[0082] Please see Figures 9 to 12 In this embodiment, the damping sleeve 181 extends vertically, and its upper end is open. The lower end of the telescopic rod assembly is located inside the damping sleeve 181, and the upper end of the telescopic rod assembly is connected to the air outlet 140. When the air outlet 140 moves vertically, the telescopic rod assembly can extend and retract, thereby effectively supporting and damping the air outlet 140. Here, the damping sleeve 181 serves as both an installation and guide.

[0083] There can be various structures for the telescopic rod assembly. For example, in one embodiment, the telescopic rod assembly includes a first spring 182 and a first telescopic rod 183. The first spring 182 is disposed inside the damping sleeve 181. One end (lower end) of the first telescopic rod 183 is disposed inside the damping sleeve 181 and connected to the first spring 182, and the other end (upper end) is connected to the air outlet 140.

[0084] In this embodiment, the first spring 182 can be a compression spring. When the air outlet 140 moves from the air outlet position to the storage position, the air outlet 140 compresses the first spring 182 downwards. At this time, the first spring 182 applies an upward supporting force to the air outlet 140. During the process of the air outlet 140 moving from the storage position to the air outlet position, the first spring 182 applies an upward driving force to the air outlet 140, thereby reducing the driving force of the drive mechanism 160 and reducing the operating power of the drive mechanism 160.

[0085] Considering the relatively long travel distance of the air outlet 140, in order for the damping mechanism 180 to achieve effective support and vibration reduction, the telescopic rod assembly can include multiple telescopic rods and springs. For example, in another embodiment, please refer to... Figures 9 to 12 The telescopic rod assembly further includes a second spring 184 and a second telescopic rod 185. The second spring 184 is disposed inside the damping sleeve 181. One end (lower end) of the second telescopic rod 185 is disposed inside the damping sleeve 181 and connected to the second spring 184. The interior of the second telescopic rod 185 is hollow and one end is open. The first spring 182 is disposed inside the second telescopic rod 185. One end of the first telescopic rod 183 is disposed inside the second telescopic rod 185, and the other end is connected to the air outlet 140.

[0086] In this embodiment, the sum of the extension / retraction of the first spring 182 and the second spring 184 is greater than or equal to the moving distance of the air outlet 140. Thus, by utilizing two stages of telescopic rods and two stages of springs, the damping mechanism 180 can effectively support and reduce vibration of the air outlet 140 during its movement. Optionally, the second spring 184 is a compression spring.

[0087] It is understood that in other embodiments, the damping mechanism 180 includes a telescopic spring, one end of which is connected to the air outlet 140 and the other end to the housing 120. The telescopic spring can not only provide a certain vibration reduction effect, but also provide support for the air outlet 140.

[0088] Please see Figures 9 to 12To ensure smoother and more reliable movement of the air outlet 140, the damping mechanism 180 and the telescopic mechanism 170 can be located on opposite sides of the air outlet 140. For example, the damping mechanism 180 can be located at the front of the air outlet 140, and the telescopic mechanism 170 at the rear; or, for another example, the damping mechanism 180 can be located on the left side of the air outlet 140, and the telescopic mechanism 170 on the right side. No specific limitations are imposed.

[0089] Please see Figures 9 to 12 To precisely control the movement distance of the air outlet 140, a limiting part 134 can be provided on the inner wall of the housing 130. The limiting part 134 is used to stop and limit the lower end of the air outlet 140. In addition, by providing the limiting part 134, when the air outlet 140 is retracted to the storage position, the limiting part 134 can also provide a certain degree of support for the air outlet 140. Specifically, the limiting part 134 can be a limiting plate, a limiting block, or a limiting frame, etc.

[0090] Please see again Figure 2 The fresh air module 120 also includes a fan assembly 190, which is mainly used to drive the fresh air flow from the fresh air inlet 132 into the fresh air duct and out of the fresh air outlet 141. The fan assembly 190 can be located within the air outlet cavity 142, or it can be located within the air inlet cavity 131; no specific limitation is made here. To ensure that more fresh air flow from the air inlet cavity 131 can flow into the air outlet cavity 142 and then out of the fresh air outlet 141 during the movement of the air outlet 140, the fan assembly 190 can be located within the air outlet cavity 142. Specifically, the fan assembly 190 can be located within the second sub-cavity 144 of the air outlet cavity 142. The fan assembly 190 includes a centrifugal fan 191 and a motor 192 that drives the centrifugal fan 191 to rotate.

[0091] It is worth mentioning that, in this embodiment of the invention, since the impeller assembly 190 is installed in the air outlet cavity 142, the overall weight of the air outlet 140 is increased. Therefore, through the synergistic effect of the telescopic mechanism 170, the damping mechanism 180 and the rolling assembly 150, the air outlet 140 can be effectively supported, ensuring the normal operation of the air outlet 140. At the same time, the vibration of the air outlet 140 can be reduced and the noise can be lowered.

[0092] In the above embodiments, the indoor unit 100 of the air conditioner further includes a purification module 200 (e.g., Figure 16 and Figure 17As shown, the purification module 200 is located in the air inlet chamber 131. Thus, the fresh air entering from the fresh air inlet 132 first flows through the purification module 200, and after being processed by the purification module 200, it flows into the air outlet chamber 142. This ensures that the fresh air flowing out from the fresh air outlet 141 is very clean, further improving the freshness of the fresh air. Optionally, the purification module 200 may include any one or more combinations of HEPA filters, plasma filters, and electrostatic precipitators.

[0093] The present invention also proposes an air conditioner, which includes an outdoor unit and an indoor unit 100. The specific structure of the indoor unit 100 is as described in the above embodiments. Since the present air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0094] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
