[0046] 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
[0047] It should be noted that if the embodiments of the present invention involve descriptions such as "first" and "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" and "second" may explicitly or implicitly include at least one of those features. Furthermore, the meaning of "and / or" throughout the text is to include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B.
[0048] This invention proposes an air conditioner indoor unit, which can be a wall-mounted air conditioner indoor unit or a floor-standing air conditioner indoor unit. The following detailed description uses a wall-mounted air conditioner indoor unit as an example.
[0049] In embodiments of the present invention, such as Figures 1 to 6 As shown, the indoor unit of the air conditioner includes a housing 100 and an air diffuser module 200; the housing 100 is provided with an air outlet 110. The air diffuser module 200 is installed at the air outlet 110, and the air diffuser module 200 includes a mounting bracket 210 and a fan wheel 220. The fan wheel 220 is rotatably mounted on the mounting bracket 210 and can rotate under the drive of the airflow from the air outlet 110.
[0050] In this embodiment, the shape of the housing 100 can be selected and designed according to the model of the indoor air conditioning unit, and is not specifically limited here. The shape of the air outlet 110 can be varied, such as elongated, circular, elliptical, rectangular, etc., and is not listed here. The overall shape of the air diffusion module 200 can also be circular, rectangular, elongated, etc. The shape of the air diffusion module 200 can be the same as or different from the shape of the air outlet 110. To further improve the air diffusion effect of the air diffusion module 200, optionally, the air diffusion module 200 is adapted to the air outlet 110. The housing 100 is also provided with an air inlet and a heat exchange duct connecting the air inlet and the air outlet 110. A heat exchanger and a heat exchange fan are provided in the heat exchange duct. The heat exchange fan drives the airflow from the air inlet into the heat exchange duct, and after heat exchange by the heat exchanger, it is blown out from the air outlet 110. By placing the air diffuser module 200 at the air outlet 110, the airflow blown out of the air outlet 110 can be dispersed by the air diffuser module 200, thereby achieving a windless effect in the indoor unit of the air conditioner. The air diffuser module 200 can only use the impeller 220 for air dispersion to achieve a windless effect at the air outlet 110. Of course, the air diffuser module 200 can also be combined with other air dispersion structures, such as micro-perforations, grille holes, etc., to achieve the air dispersion effect together with the impeller 220, thereby improving the windless effect of the air diffuser module 200. The air diffuser module 200 can be fixedly installed at the air outlet 110, or it can be detachably installed at the air outlet 110. The air diffuser module 200 can also be movably installed at the air outlet 110, for example, so that the air diffuser module 200 can be rotated or moved at the air outlet 110. The housing 100 specifically includes a frame and a panel. The panel is installed on the frame, so the air diffuser module 200 can be connected to the panel or the frame.
[0051] The impeller 220 can be either an axial flow impeller 220 or a vortex impeller 220, as long as it can be blown by airflow and disperse the airflow while rotating. There can be one or multiple impellers 220. When multiple impellers 220 are used, they can be spaced apart along the length of the air outlet 110. The impeller 220 can be mounted to the housing 100 via a mounting bracket 210. Alternatively, the mounting bracket 210 can be mounted on other structures of the air distribution module 200. The mounting bracket 210 can consist of one or more supporting ribs, as long as it allows the impeller 220 to rotate. The wind resistance of the mounting bracket 210 should be minimized to increase the overall airflow of the air distribution module 200. The impeller 220 is rotatably mounted on the mounting bracket 210 and can rotate under the drive of the airflow from the air outlet 110. The impeller 220 and the mounting bracket 210 can be rotatably connected via bearings. For example, the outer ring 223 of the impeller 220 and the mounting bracket 210 can be rolled together via multiple rollers, allowing the impeller 220 to be blown by the airflow from the outlet 110 and thus rotate. Alternatively, the impeller 220 and the mounting bracket 210 can be rotatably connected via a structure of a rotating shaft 231 and a bearing. The rotating shaft 231 can rotate relative to the bearing, while the shaft 231 is fixed to the impeller 220, and the bearing is fixed to the mounting bracket 210, allowing the impeller 220 to rotate relative to the mounting bracket 210 under the drive of the airflow. Other methods can also be used to achieve a rotatable connection between the impeller 220 and the mounting bracket 210, as long as the friction between the impeller 220 and the mounting bracket 210 is low, allowing the impeller 220 to rotate under the influence of the airflow.
[0052] The present invention relates to an air conditioning indoor unit by setting an air dispersing module 200 at the air outlet 110 of the housing 100. The air dispersing module 200 includes a mounting bracket 210 and a fan wheel 220. The fan wheel 220 is rotatably mounted on the mounting bracket 210 and can rotate under the drive of the airflow from the air outlet 110. The airflow blown out of the air outlet 110 can be cut, dispersed, diverted and stirred by the fan wheel 220, making the airflow from the air outlet 110 softer and greatly improving the windless effect. The wind resistance of the fan wheel 220 is greatly reduced compared to micropores, so that the air dispersing module 200 can achieve the windless effect of the air conditioning indoor unit without affecting the airflow of the air outlet 110. Furthermore, the rotation of the impeller 220 does not require a drive mechanism, which simplifies the overall structure of the air dispersing module 200. At the same time, the rotation speed of the impeller 220 can be adjusted in real time according to the wind speed of the air outlet. That is, the faster the air outlet speed is, the faster the impeller 220 rotates, and the stronger the effect of the impeller 220 in dispersing the air outlet speed is. This allows the effect of the impeller 220 in dispersing the air to match the wind speed of the air outlet, further improving the overall operational reliability of the air dispersing module 200.
[0053] In one embodiment, please refer to Figures 6 to 12 The air distribution module 200 also includes a transmission structure 230, and the impeller 220 is rotatably connected to the mounting bracket 210 through the transmission structure 230.
[0054] In this embodiment, the transmission structure 230 may specifically include a sliding bearing, a rolling bearing 235, a rotating shaft, and other structures. It is understood that when the transmission structure 230 rotates, its friction is smaller compared to when the air distribution module 200 is directly rotatably connected to the mounting bracket 210. Thus, the impeller 220 is rotatably connected to the mounting bracket 210 via the transmission structure 230, allowing the impeller 220 to be blown even with a smaller airflow and speed. In other words, under the same airflow and speed, the impeller 220 rotates faster, resulting in smoother rotation and a better effect on dispersing airflow.
[0055] Furthermore, such as Figures 6 to 10 As shown, the transmission structure 230 includes a rotating shaft 231 and a support member 232. The support member 232 is connected to the mounting bracket 210. One end of the rotating shaft 231 is fixedly connected to the wind turbine 220, and the other end is rotatably connected to the support member 232.
[0056] In this embodiment, a shaft hole is provided at the hub 221 of the impeller 220, allowing the rotating shaft 231 to be interference-fitted with the shaft hole of the impeller 220 for a fixed connection. The rotating shaft 231 can be rotatably connected to the support member 232 via a rolling bearing 235 or a sliding bearing. Alternatively, the rotating shaft 231 can be made of a material with high strength and hardness, the support member 232 can be made of a wear-resistant material, or both the rotating shaft 231 and the support member 232 can be made of self-lubricating materials to reduce friction between them. The support member 232 can be detachably connected to the mounting bracket 210 using snap-fit, screws, or other means. By additionally setting a rotating shaft 231 and a support member 232, the impeller 220 and the mounting bracket 210 can be rotatably connected. Compared with the impeller 220 being directly connected to the mounting bracket 210, it is easier to replace and maintain the transmission structure 230. Moreover, the transmission structure 230 with rotating shaft 231 and support member 232 is simpler, more stable and reliable than the method of directly connecting the impeller 220 and the mounting bracket 210 through roller transmission.
[0057] In one embodiment, please refer to Figures 7 to 10 The support member 232 includes a support base 2321 and a support cover 2322. The support base 2321 and the support cover 2322 are connected by a self-aligning structure. The support base 2321 is mounted on the mounting bracket 210. The rotating shaft 231 is rotatably connected to the support base 2321 and / or the support cover 2322.
[0058] In this embodiment, the support base 2321 and the support cover 2322 are detachably connected. For example, they can be connected by snap-fit, magnetic attraction, or other means. It is understood that the self-aligning structure can be an additional structure, such as a self-aligning bearing or self-aligning roller. The self-aligning structure can be formed by the structure of the support base 2321 and the support cover 2322 themselves. For example, a first conical surface 11 can be provided on the support base 2321, and a second conical surface 31 can be provided on the support cover 2322, so that the first conical surface 11 and the second conical surface 31 cooperate. It is understood that when the shaft 231 rotates, it will generate radial runout, which will cause the support cover 2322 to deflect relative to itself. By connecting the support base 2321 and the support cover 2322 through the self-aligning structure, this radial deviation can be automatically adjusted, allowing the shaft 231 to rotate smoothly relative to the support member 232, thereby improving the operational stability and reliability of the wind turbine 220.
[0059] Furthermore, such as Figures 8 to 10As shown, the support base 2321 includes a self-aligning boss 10 extending axially along the shaft 231, and the support cover 2322 includes a connecting periphery 30 extending axially along the shaft 231. The outer peripheral surface of the self-aligning boss 10 is provided with a first conical surface 11, and the inner peripheral surface of the connecting periphery 30 is provided with a second conical surface 31 that is adapted to the first conical surface 11. The connecting periphery 30 is sleeved on the periphery of the self-aligning boss 10, and the first conical surface 11 and the second conical surface 31 are fitted together.
[0060] In this embodiment, the entire outer peripheral surface of the self-aligning boss 10 can be set as the first conical surface 11, or only a portion of the outer peripheral surface of the self-aligning boss 10 can be set as the first conical surface 11. Thus, when the support cover 2322 is connected to the support base 2321, the connecting periphery 30 of the support cover 2322 is fitted around the periphery of the self-aligning boss 10, allowing the self-aligning boss 10 and the connecting periphery 30 to fit together through the first conical surface 11 and the second conical surface 31. Therefore, when the rotating shaft 231 experiences radial runout, the concentricity can be adjusted through the cooperation of the first conical surface 11 and the second conical surface 31, thereby improving the operational stability of the wind turbine 220. The self-aligning fit between the support base 2321 and the support cover 2322 achieved through the first conical surface 11 and the second conical surface 31 is simpler and easier to install and manufacture compared to achieving the self-aligning fit between the support base 2321 and the support cover 2322 through other self-aligning structures. Of course, in other embodiments, a first conical surface 11 can be provided on the inner peripheral surface of the self-aligning boss 10, and a second conical surface 31 can be provided on the outer peripheral surface of the connecting periphery 30, so that the self-aligning boss 10 is sleeved on the periphery of the connecting periphery 30, and the first conical surface 11 and the second conical surface 31 are in contact, so as to realize the self-aligning connection between the support base 2321 and the support cover 2322.
[0061] In one embodiment, please refer again Figures 8 to 10 The support cover 2322 and the support base 2321 enclose a rotating cavity 2323. The rotating shaft 231 includes a limiting boss 2311, a first rod segment 2312 connected to one end of the limiting boss 2311, and a second rod segment 2313 connected to the other end of the limiting boss 2311. The limiting boss 2311 is located in the rotating cavity 2323. The first rod segment 2312 is rotatably connected to the support base 2321. The second rod segment 2313 passes through the support cover 2322 and is fixedly connected to the impeller 220.
[0062] In this embodiment, the limiting boss 2311 is provided in the rotating cavity 2323, thereby restricting the axial movement of the rotating shaft 231 and preventing the rotating shaft 231 from falling off the support member 232. Specifically, the rotating shaft 231 can be made of a self-lubricating material, and the support cover 2322 and the support member 232 can be made of wear-resistant materials, so that the first rod segment 2312 can be directly rotatably connected to the support base 2321, and the second rod segment 2313 can be rotatably connected to the support cover 2322, thereby saving the cost of the sliding sleeve. Furthermore, by making the first rod segment 2312 rotatably connected to the support base 2321, and the second rod segment 2313 passing through the support cover 2322 and fixedly connected to the impeller 220, when the rotating shaft 231 as a whole undergoes radial deflection, it can be adjusted by the self-aligning structure of the support base 2321 and the support cover 2322, thereby ensuring the rotational stability of the impeller 220.
[0063] Furthermore, such as Figure 8 and Figure 9 As shown, it also includes a first sliding sleeve 233 and a second sliding sleeve 234. The first sliding sleeve 233 is embedded in the inner wall of the support base 2321, and the second sliding sleeve 234 is embedded in the inner wall of the support cover 2322. The limiting boss 2311 is provided between the first sliding sleeve 233 and the second sliding sleeve 234. The first rod segment 2312 is rotatably connected to the support base 2321 through the first sliding sleeve 233, and the second rod segment 2313 is rotatably connected to the support cover 2322 through the second sliding sleeve 234.
[0064] Understandably, the first sliding sleeve 233 and the second sliding sleeve 234 are made of wear-resistant materials with low friction. Specifically, the first sliding sleeve 233 can be fitted into the inner wall of the support base 2321 via an interference fit, and the second sliding sleeve 234 can also be fitted into the inner wall of the support cover 2322 via an interference fit. By rotatably connecting the first rod segment 2312 to the support base 2321 via the first sliding sleeve 233, and the second rod segment 2313 to the support cover 2322 via the second sliding sleeve 234, when the impeller 220 is rotated by the airflow, it drives the rotating shaft 231 to rotate within the sliding sleeves. This reduces the rotational friction of the rotating shaft 231, lowers the rotational resistance, and makes the rotation of the rotating shaft 231 smoother and noiseless. By positioning the limiting boss 2311 between the first sliding sleeve 233 and the second sliding sleeve 234, the limiting boss 2311 contacts the first sliding sleeve 233 and the second sliding sleeve 234. Compared to making the limiting boss 2311 directly contact the support seat 2321 and the support cover 2322, the rotational friction of the rotating shaft 231 is further reduced.
[0065] Specifically, please refer to Figures 8 to 10 ,like Figures 7 to 10As shown, the support member 232 includes a support base 2321 and a support cover 2322, which are interlocked. The interlocking connection between the support base 2321 and the support cover 2322 can be achieved by providing a buckle on one of the support base 2321 and the support cover 2322, and a slot on the other. This interlocking connection provides a more stable and reliable connection compared to other connection methods, and facilitates disassembly. Furthermore, it facilitates alignment between the support base 2321 and the support cover 2322. Additionally, the support member 232 is interlocked with the mounting bracket 210. This interlocking connection can also be achieved by providing a buckle on one of the support member 2321 and the mounting bracket 210, and a slot on the other. By making the support 232 snap-fit with the mounting bracket 210, the connection is more stable and reliable compared to other connection methods, and both are easier to disassemble.
[0066] In one embodiment, please refer again Figures 7 to 10 The outer peripheral wall of the support cover 2322 is provided with multiple locking protrusions 40, which are spaced apart around the circumference of the support cover 2322. The support base 2321 is provided with multiple locking arms 20 arranged at intervals. The mounting bracket 210 is provided with multiple spring buckles 212 arranged at intervals. Each locking arm 20 is correspondingly locked with a locking protrusion 40, and the locking protrusion 40 between two adjacent locking arms 20 is locked with the spring buckle 212.
[0067] In this embodiment, the number of retaining arms 20 can be set to three, and the number of spring clips 212 can also be set to three. Specifically, a slot can be provided on the retaining arm 20 so that the retaining protrusion 40 can engage with the slot of the retaining arm 20. Specifically, the spring clip 212 includes an elastic arm and a fastening part provided at the free end of the elastic arm. The fastening part and the bottom wall of the mounting bracket 210 form an installation space. The support base 2321 is provided in the installation space, and the fastening part engages with the retaining protrusion 40 to improve the overall connection stability. The two adjacent retaining arms 20 are hollowed out so that after the support cover 2322 is connected to the support base 2321, the retaining protrusion 40 between the two adjacent retaining arms 20 can be exposed outside the support base 2321. This allows the retaining protrusion 40 between the two adjacent retaining arms 20 to engage with the spring clip 212. In this way, one of the two adjacent latches 40 on the support cover 2322 is connected to the spring buckle 212 on the mounting bracket 210, and the other is connected to the retaining arm 20 on the support base 2321. This allows the support base 2321 to be indirectly connected to the mounting bracket 210 through the support cover 2322, thereby simplifying the structure of the support base 2321 and making the connection between the support cover 2322, the support base 2321, and the mounting bracket 210 more stable and reliable. The structure of the entire support component 232 is also simpler and smaller.
[0068] In one embodiment, such as Figure 11 and Figure 12 As shown, the transmission structure 230 includes a rolling bearing 235, and the impeller 220 is rotatably connected to the mounting bracket 210 via the rolling bearing 235. There are many types of rolling bearings 235, and the specific type can be selected according to actual needs; no limitation is made here. By making the impeller 220 rotatably connected to the mounting bracket 210 via the rolling bearing 235, the sliding friction between the impeller 220 and the mounting bracket 210 is converted into rolling friction, thereby reducing the frictional force between the impeller 220 and the mounting bracket 210, making the rotation of the impeller 220 under airflow drive smoother and noiseless.
[0069] Further, please refer to Figure 11 and Figure 12 The mounting bracket 210 has a protruding pivot 211. The rolling bearing 235 includes an inner ring 2351 and an outer ring 2352 that can rotate relative to each other. The outer ring 2352 is connected to the impeller 220, and the inner ring 2351 is connected to the pivot 211. The outer ring 2352 is fitted around the outer periphery of the inner ring 2351. The rolling bearing 235 also includes a rolling element disposed between the inner ring 2351 and the outer ring 2352. The rolling element can be a sphere, cylinder, cone, etc., and different types of rolling elements can be selected according to actual needs. Specifically, a cylindrical cavity can be provided at the hub 221 of the impeller 220 so that the outer ring 2352 is embedded in the cylindrical cavity. Elastic buckles can also be provided around the cylindrical cavity so that the outer ring 2352 can be detachably installed in the cylindrical cavity. It is understandable that the outer ring 2352 is fixedly connected to the impeller 220, meaning that the outer ring 2352 cannot rotate relative to the impeller 220, and the inner ring 2351 is fixedly connected to the pivot 211, meaning that the inner ring 2351 cannot rotate relative to the pivot 211. This converts the rotational friction between the impeller 220 and the pivot 211 into the rolling friction of the rolling elements of the rolling bearing 235. Compared to setting the pivot 211 on the impeller 220, directly embedding the outer ring 2352 within the impeller 220 improves the rotational stability of the impeller 220.
[0070] Based on the above embodiments, a limiting buckle 2111 is further provided at the free end of the pivot 211. The inner ring 2351 is fitted onto the pivot 211 and axially limited by the limiting buckle 2111, while the outer ring 2352 is embedded in the hub 221 of the wind turbine 220. By providing the limiting buckle 2111 at the free end of the pivot 211, axial movement of the inner ring 2351 can be prevented, as well as detachment of the rolling bearing 235 from the pivot 211. To facilitate the fitting of the inner ring 2351 onto the pivot 211, the pivot 211 can optionally be configured as an open-type elastic buckle. This allows the pivot 211 to deform radially, making it easier to fit the rolling bearing 235 onto the pivot 211 and to remove the rolling bearing 235 from the pivot 211, thereby facilitating the maintenance and replacement of the rolling bearing 235.
[0071] In one embodiment, such as Figures 1 to 6 As shown, multiple impellers 220 are configured, spaced apart along the length of the air outlet 110. By spaced multiple impellers 220 along the length of the air outlet 110, each impeller 220 is smaller than a single large impeller 220, making it easier to be blown by the airflow. Furthermore, by dividing the air outlet 110 into multiple small air dispersion areas and dispersing the airflow from various directions with multiple impellers 220, the overall air dispersion effect of the air dispersion module 200 is improved, resulting in a better windless effect for the entire indoor air conditioning unit.
[0072] Furthermore, please refer to again Figures 1 to 6 The air distribution module 200 also includes a mounting plate 240, which has multiple through holes 241. Each through hole 241 has a mounting bracket 210, and each mounting bracket 210 has a corresponding impeller 220.
[0073] In this embodiment, the mounting plate 240 is elongated. Through holes 241 are provided on the mounting plate 240, with each through hole 241 housing a fan wheel 220. Compared to directly mounting the fan wheel 220 to the air outlet 110 via the mounting bracket 210, the mounting plate 240 can concentrate the airflow from the air outlet 110 through the through holes 241. This ensures that the airflow from the air outlet 110 is dispersed by the fan wheel 220, further improving the overall airflow distribution effect of the ventilation module 200. Optionally, multiple ventilation holes are provided on the mounting plate 240, avoiding the through holes 241. By providing multiple ventilation holes, the airflow of the entire ventilation module 200 can be increased without affecting the windless effect.
[0074] In one embodiment, such as Figure 1 and Figure 6As shown, the impeller 220 is a vortex impeller 220. It can be understood that a vortex impeller 220 refers to an impeller whose blades 222 are curved or angled with the airflow direction, causing the airflow passing through the impeller 220 to form a vortex, or causing the airflow direction to be inconsistent with the airflow direction. This effectively disperses and agitates the airflow, making the airflow gentler.
[0075] Further, please refer to Figure 6 The wind turbine 220 includes a hub 221, an outer ring 223, and multiple blades 222 connecting the hub 221 and the outer ring 223. The blades 222 are circumferentially spaced around the outer periphery of the hub 221, forming a ring shape. The blade surface of each blade 222 is angled to the axial direction of the wind turbine 220. Specifically, the ring shape of the blades 222 can be triangular, near-triangular, heart-shaped, rectangular, etc. Since the blade surface of each blade 222 is angled to the axial direction of the wind turbine 220, meaning each blade 222 is inclined, airflow can exit between adjacent blades 222. Furthermore, because the gaps between adjacent blades 222 are small, when airflow passes between adjacent blades 222, the thrust can be effectively applied to the blades 222, thereby driving the entire wind turbine 220 to rotate. By setting the blades 222 in a ring shape, air can effectively pass through the middle of each blade 222, thereby increasing the overall airflow of the impeller 220. By designing the impeller 220 with the blades 222 arranged in a ring shape, with adjacent blades 222 spaced apart, and multiple blades 222 connected to the hub 221 and the outer ring 2352, it is easier to be blown by airflow compared to a traditional axial flow impeller 220. In addition to dispersing the outgoing airflow, it can further increase the airflow of the impeller 220.
[0076] In one embodiment, such as Figures 1 to 5 As shown, the air dissipation module 200 is movably mounted on the housing 100 to have a first position corresponding to the air outlet 110 and a second position removed from the air outlet 110.
[0077] In this embodiment, the air diffuser module 200 can be slidably connected to the housing 100 or rotatably connected to the housing 100, as long as it can switch between the first and second positions. It is understood that when the indoor unit of the air conditioner needs to activate the windless mode, the air diffuser module 200 moves to the first position corresponding to the air outlet 110, thus effectively dispersing the airflow from the air outlet 110 to achieve a windless effect. When the indoor unit needs to activate the regular air supply mode, the air diffuser module 200 can be moved to the second position, away from the air outlet 110. It should be noted that when the air diffuser module 200 moves to the second position, it completely moves away from the air outlet 110, meaning that the air diffuser module 200 will not obstruct the air outlet 110, allowing the air outlet 110 to discharge air normally and achieve rapid heating or cooling of the room. When the air diffuser module 200 is in the second position, it can be concealed within the housing 100 or exposed outside the housing 100. The air diffuser module 200 can be manually switched between the first and second positions. In practice, the indoor unit also includes a drive mechanism, drive components, and transmission components. These components are connected to the air diffuser module 200, and the drive components drive the transmission components to switch the air diffuser module 200 between the first and second positions. Specifically, the drive component can be a drive motor, and the transmission components can be a gear or rack structure. There can be one drive mechanism, or two drive mechanisms can be installed at both ends of the air diffuser module 200 along its length to synchronously drive its movement. This improves the operational stability of the air diffuser module 200. The housing 100 specifically includes a panel and a frame. The panel is mounted on the frame, so the air diffuser module 200 and the drive mechanism can be mounted on either the frame or the panel.
[0078] Further, please refer to Figure 4 and Figure 5 The air diffuser module 200 is vertically movable and installed on the housing 100. When the air diffuser module 200 is in the second position, it is hidden inside the housing 100. By driving the air diffuser module 200 to be vertically movable and installed on the housing 100 via a drive mechanism, when the air diffuser module 200 is in the second position, the space behind the panel can be fully utilized, allowing the air diffuser module 200 to be hidden behind the panel. This makes the air diffuser module 200 less prone to dust accumulation and also makes the overall appearance of the indoor air conditioning unit more concise and aesthetically pleasing.
