Description

Technical Field

[0001] This utility model relates to the field of wall-mounted air conditioning technology, and in particular to a wall-mounted air conditioning indoor unit. Background Technology

[0002] Household air conditioning units can be divided into two types based on their structure: modular air conditioners and split-type air conditioners. Among them, split-type air conditioners commonly include cabinet air conditioners and wall-mounted air conditioners. Wall-mounted air conditioners are widely popular because of their compact structure and ability to save floor space.

[0003] In related technologies, most existing wall-mounted air conditioner vertical air vanes have a connecting rod at the air outlet to connect the various blades together, achieving the effect of swinging in the same direction. However, the connecting rod located at the air outlet affects the aesthetics and increases wind resistance and noise. Furthermore, when disassembling and cleaning the vertical air vane, the motor driving the blades is also removed, which can affect the live parts and pose a safety hazard. Utility Model Content

[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-13 This invention describes a wall-mounted air conditioner indoor unit according to an embodiment of the present invention.

[0021] like Figures 1-13 As shown, a wall-mounted air conditioner indoor unit includes: a casing, a heat exchanger, a fan, and an air swing assembly. The casing is installed indoors and forms the overall appearance of the wall-mounted air conditioner indoor unit.

[0022] refer to Figure 1 As shown, the housing 100 is generally rectangular in shape. The housing 100 has a top end and a bottom end, which are opposite ends of the housing 100 in the height direction (vertical direction). The left side and right side of the housing 100 are opposite sides in the length direction (horizontal direction), and the front side and rear side of the housing 100 are opposite sides in the thickness direction (front-back direction).

[0023] The housing 100 is located at the top of an indoor space or in the upper part of an indoor space. The front of the housing 100 faces the user, and the rear of the housing 100 faces the wall, making it suitable for connection with the wall.

[0024] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.

[0025] refer to Figure 1 As shown, the housing 100 may include an outer cover 1 and a front panel. The outer cover 1 has an air inlet 11 and an air outlet 12. The outer cover 1 is generally in the shape of a cuboid frame. The front side of the outer cover 1 has a frame opening. The front panel is located on the front side of the outer cover 1 and is used to form the front appearance of the wall-mounted air conditioner indoor unit.

[0026] An air duct 3 is formed inside the outer casing 1. The air duct 3 is used to house and fix various components in the indoor unit of the air conditioner, which can prevent external objects from colliding with the various components inside the outer casing 1, thereby improving the reliability of the indoor unit of the air conditioner during transportation or installation.

[0027] The outer casing 1 has an air inlet 11. The air inlet 11 is connected to the air duct 3. The air inlet 11 serves as the inlet for external air to flow into the casing 100, allowing indoor air to enter the air duct 3 through the air inlet 11.

[0028] The outer casing 1 has an air outlet 12. The air outlet 12 is connected to the air duct 3 and serves as the outlet for the heat exchange airflow inside the casing 100, allowing the airflow inside the air duct 3 to flow out through the air outlet 12.

[0029] The air inlet 11 can be located at the top of the outer casing 1. The air outlet 12 can be located at the bottom of the outer casing 1 and near the front side of the outer casing 1, that is, the air outlet 12 is located at the bottom front side of the outer casing 1. In this embodiment, when the wall-mounted air conditioner indoor unit is working, the wall-mounted air conditioner indoor unit takes in air from the top and exits air to the front, which is convenient for installation.

[0030] The air outlet 12 can be elongated and can extend along the length of the casing 100, which improves the aesthetics of the wall-mounted air conditioner indoor unit.

[0031] In some embodiments of this application, reference is made to Figures 1-3 As shown, the housing 100 may also include a base 2, with an outer cover 1 covering the front side of the base 2, and an air duct 3 defining the space between the outer cover 1 and the base 2. That is, the base 2 forms the rear side of the wall-mounted air conditioner indoor unit, and the base 2 is suitable for mounting on the wall.

[0032] The outer cover 1 has an open rear side, and is placed on the front side of the base 2 and connected to the base 2. An air outlet duct 3 is defined between the outer cover 1 and the base 2.

[0033] In some embodiments of this application, the indoor unit of the wall-mounted air conditioner may include a heat exchanger. The heat exchanger extends along the length of the casing 100 and is disposed inside the outer cover 1 for heat exchange with the airflow inside the casing 100.

[0034] The heat exchanger is located between the air inlet 11 and the air outlet 12 to exchange heat with the air entering from the air inlet 11, and then exhaust it to the room from the air outlet 12.

[0035] In some embodiments of this application, the indoor unit of the wall-mounted air conditioner may include a fan. The fan is disposed inside the outer casing 1, and the axial direction of the fan extends along the length of the casing 100. It is used to drive indoor air outside the casing 100 into the air duct 3 inside the casing 100 through the air inlet 11. The fan drives the air in the air duct 3 to flow along the air inlet 11 toward the air outlet 12.

[0036] The fan is located below the heat exchanger. The heat exchanger can be located inside the air inlet 11. The fan can be located on the side of the heat exchanger away from the air inlet 11. That is, in the airflow direction within the casing 100, the fan is downstream of the heat exchanger.

[0037] When the indoor unit of the wall-mounted air conditioner is running, indoor air enters the outer casing 1 from the air inlet 11 under the operation of the fan. The indoor air in the air duct 3 flows through the heat exchanger for heat exchange. The heat-exchanged airflow is discharged to the outside of the room through the air outlet 12, thereby enabling the air conditioner to cool and heat, and play a role in regulating the indoor temperature to achieve a comfortable temperature.

[0038] In some embodiments of this application, the swing assembly 4 is disposed in the outer cover 1 and located below the fan. The heat exchange airflow is output in different directions by the swing of the swing assembly 4. The swing assembly 4 receives the airflow blown out by the fan and changes the blowing angle of the airflow by its own rotation, so as to achieve "wide-area air supply" or "fixed-point air supply" and avoid the airflow blowing directly in a certain direction, which would cause discomfort.

[0039] Continue to refer to Figures 1-5 and Figure 13 As shown, the swing assembly 4 includes a swing blade 41, a wind vane seat 42, a connecting rod 43, and a motor 44. The swing blade 41 is located on the side of the wind vane seat 42 facing the air duct 3, and the connecting rod 43 is located on the side of the wind vane seat 42 away from the air duct 3. The lower ends of multiple swing blades 41 pass through the wind vane seat 42 and are linked to the connecting rod 43. The motor 44 is driven by one of the swing blades 41.

[0040] Specifically, the design of "motor 44 driving a single blade 41 + linkage 43 linking the rest of the blades 41" ensures the synchronization of the blades 41. The linkage 43 acts as a "rigid linkage intermediary". When the motor 44 drives the active blade 41 to rotate, the linkage 43 will drive the rest of the driven blades 41 to rotate at the same angle and speed. This avoids the "misalignment" of the blades 41 caused by the control error of multiple motors 44, and ensures that the airflow can uniformly cover the target area at the preset angle.

[0041] By positioning the connecting rod 43 on the side of the air deflector seat 42 away from the air duct 3, it appears hidden behind the air deflector seat 42 when viewed from the air outlet 12. This avoids the connecting rod 43 affecting the airflow, reducing wind resistance and noise. Furthermore, the concealed design of the connecting rod 43 improves aesthetics and reduces dust accumulation.

[0042] Similarly, the fan is also located on the side of the air deflector seat 42 away from the air duct 3, so that the lower end of the active swing blade 41 passes through the air deflector seat 42 and is connected to the fan drive. In this way, the fan is concealed, avoiding its impact on the air outlet and reducing dust accumulation.

[0043] Compared to placing the fan at one end of the air deflector base 42 in the left-right direction, which requires a complex transmission structure to rotate the swing blade 41, this application places the fan at the rear of the air deflector base 42, directly driving the active swing blade 41 to rotate, resulting in a simple structure and convenient installation.

[0044] The base 2 has a mounting groove 21 on the side facing the air duct 3. The air plate seat 42 is detachably installed in the mounting groove 21. The mounting groove 21 has a receiving groove 22 for placing the motor 44, and the motor 44 is fixed to the base 2.

[0045] refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the base 2 has a mounting groove 21 on the side facing the air duct 3 so that the air deflector seat 42 can be detachably installed in the mounting groove 21, making it easy to remove the air deflector seat 42 to clean the multiple blades 41 and the air deflector seat 42.

[0046] When installing the swing assembly 4, the motor 44 is fixed in the receiving groove 22 of the base 2, the wind plate seat 42 and its swing blades 41 are fixed in the mounting groove 21 of the base 2, and the lower end of the active swing blades 41 is aligned with the motor shaft 441 of the fan for insertion and engagement. The installation is simple.

[0047] Since the oscillating blades 41 and their fan plate holders 42 are located at the air outlet 12, dust easily accumulates there, requiring regular maintenance and cleaning. This application addresses this by fixing the fan to the base 2 and detachably mounting the fan plate holder 42 to the base 2, making the fan and base 2 a single unit, while the fan plate holder 42 and oscillating blades 41 form another unit. When removing the fan plate holder 42 and its oscillating blades 41 for cleaning, no live parts are removed, ensuring safety and reliability. Furthermore, the fan plate holder 42 can be installed directly without wiring, simplifying the operation.

[0048] Therefore, by placing the connecting rod 43 and the fan on the side of the air deflector seat 42 away from the air duct 3, this application hides the connecting rod 43 and the fan behind the air deflector seat 42, which reduces wind resistance, lowers noise, and also reduces dust accumulation. Furthermore, by continuing to hide and fix the fan to the base 2, the air deflector seat 42 is detachably installed on the base 2, making the fan and base 2 a single unit. When the air deflector seat 42 and its blades 41 are removed for cleaning, no live parts are brought out, ensuring safety and reliability; and when installing the air deflector seat 42 and its blades 41, no wiring is required, allowing for direct installation and improving operational convenience.

[0049] In some embodiments of this application, an opening groove 23 is formed in the mounting groove 21. The opening groove 23 extends along the width direction. The wind plate seat 42 is provided with elastic buckles 421 on both sides along the width direction. The elastic buckles 421 pass through the opening groove 23 and are engaged with the structures at both ends of the opening groove 23 in the width direction.

[0050] like Figure 5 , Figure 6 and Figure 10 As shown, the elastic buckle 421 is engaged at both ends of the opening slot 23 in the width direction within the mounting groove 21, meaning that the air deflector seat 42 is completely locked in the width direction (unable to move left or right). Simultaneously, after the elastic buckle 421 passes through the opening slot 23, the overlapping structure of its "engaging part" with the edge of the opening slot 23 restricts the air deflector seat 42 from detaching in the height direction (e.g., preventing the air deflector seat 42 from falling out of the mounting groove 21 due to gravity or vibration), achieving "two-dimensional spatial positioning." Compared to the "destructive disassembly" of bolted connections (such as stripped screws or broken plastic studs), the disassembly process of this structure is more convenient and non-destructive.

[0051] Furthermore, during air conditioner operation, internal components experience temperature fluctuations due to heat exchange (such as the thermal expansion and contraction of plastic parts). Based on the design of the opening slot 23, the elastic buckle 421 can "absorb" dimensional changes: it slightly expands when the temperature rises and contracts when the temperature drops, always maintaining a close fit with the opening slot 23, avoiding the "risk of loosening" caused by thermal expansion and contraction of traditional rigid connections (such as screws). Moreover, because the elastic buckle 421 and the opening slot 23 are designed together, it acts as an "elastic buffer" between the air deflector base 42 and the mounting groove 21. When the air deflector base 42 is subjected to vibration or impact, the deformation of the elastic buckle 421 can absorb some energy, preventing vibration from being directly transmitted to the mounting groove 21 and the casing 100, thereby reducing low-frequency noise generated by "structural resonance".

[0052] Furthermore, since the opening slot 23 extends along its width, it means that during assembly, the elastic clips 421 on both sides of the air deflector seat 42 do not need to be aligned with a specific point on the opening slot 23 with "absolute precision." As long as the elastic clips 421 enter the "extension range" of the opening slot 23, they can slide along the slot to the engaging position, significantly reducing operational requirements and improving assembly error tolerance.

[0053] In some embodiments of this application, at least one end of the opening slot 23 in the width direction is provided with a locking block 24, and a groove 422 is formed on the elastic buckle 421. After the elastic buckle 421 passes through the opening slot 23, the locking block 24 is locked in the groove 422, and the bottom of the elastic buckle 421 is engaged with the locking block 24.

[0054] refer to Figure 6 As shown, after the elastic buckle 421 passes through the opening slot 23, the locking block 24 is precisely embedded in the groove 422 of the buckle, and the two form a "mortise and tenon" mechanical lock. This structure directly locks the elastic buckle 421 in the height direction (completely preventing the elastic buckle 421 from falling out of the opening slot 23) and the width direction (the side wall of the groove 422 fits against the locking block 24, limiting the buckle's left and right displacement), fundamentally solving the "loosening problem that may occur if only elastic pre-tightening is used", and realizing the "double fixation" of the wind vane seat 42.

[0055] The locking block 24 of the opening slot 23 can be integrally injection molded with the mounting slot 21 (such as the base 2), and the groove 422 of the elastic buckle 421 can also be processed simultaneously in the injection molding process of the buckle, without the need for additional processing steps, thus achieving "performance upgrade without increasing cost".

[0056] Among them, the locking block 24 is usually a "protruding small square" on the edge of the opening slot 23, and the groove 422 is a "corresponding recess" on the buckle. Both are "embedded" designs, which will not occupy the space outside the mounting slot 21 like bolts and nuts, and are fully adapted to the layout requirements of the narrow internal gap of the mounting slot 21.

[0057] In some embodiments of this application, the wind plate seat 42 is provided with limiting plates 423 at at least both ends along the width direction. The limiting plates 423 are bent toward the mounting groove 21. The limiting plates are matched with the groove wall of the mounting groove 21 and abut against the bottom of the mounting groove 21.

[0058] refer to Figure 12 As shown, in the width direction, the limiting plates 423 at both ends of the deflector seat 42 are tightly fitted with the two side walls of the mounting groove 21 in the width direction (or with a very small fitting gap), forming a "clamping" rigid constraint. This structure directly locks the displacement of the deflector seat 42 in the width direction, preventing the deflector seat 42 from moving left and right, and avoiding problems such as friction between the swing blade 41 and the side wall of the air duct 3, and misalignment of the connecting rod 43.

[0059] In the vertical direction, the limiting plate 423 extends toward the mounting groove 21 and abuts against the bottom of the groove, which is equivalent to providing "two-end support points" for the wind deflector base 42, forming a "top-locking and bottom-supporting" force balance structure with the elastic buckle 421. On the one hand, it can bear the self-weight of components such as the wind deflector base 42, the swing blade 41, and the connecting rod 43, avoiding the elastic buckle 421 from bearing vertical load alone for a long time, which would lead to elastic decay and buckle deformation; on the other hand, when the swing blade 41 rotates and generates an upward reaction force, the supporting force of the groove bottom on the limiting plate 423 can directly offset the force, preventing the wind deflector base 42 from tilting upward as a whole.

[0060] In the front-to-back direction, the extension length and shape of the limiting plate 423 can be adapted to the depth of the mounting groove 21. When the limiting plate 423 is fully in contact with the bottom of the groove, the front-to-back position of the air deflector 42 is also indirectly limited, ensuring that the mounting surface of the air deflector 42 is fully in contact with the reference surface of the mounting groove 21, avoiding the air deflector 42 from "tilting forward or backward" and causing the angle deviation of the blade 41, thus ensuring the air outlet direction.

[0061] Therefore, by cooperating with the "groove wall" and "groove bottom" of the mounting groove 21, the limiting plate 423 restricts the ineffective displacement of the wind plate seat 42 from three spatial dimensions, completely solving the possible problems of "loosening and shifting".

[0062] In some embodiments of this application, an installation space 45 is defined between the air deflector 42 and the mounting groove 21, and the connecting rod 43 is movably disposed in the installation space 45.

[0063] refer to Figure 12As shown, the connecting rod 43, as the core transmission component linking the oscillating blades 41, directly affects the oscillation accuracy. The mounting space 45, formed by the air deflector seat 42 and the mounting groove 21, creates a relatively enclosed "chamber," completely isolating the connecting rod 43 from other components inside the air conditioner (such as the evaporator, condensate drip tray, and wiring harness). This effectively prevents friction and snagging between the connecting rod 43 and other components during rotation, avoids condensate dripping from the evaporator, and prevents dust accumulation at the hinge of the connecting rod 43, which could lead to corrosion and jamming (especially preventing dust from entering the shaft hole mating area of ​​the connecting rod 43, maintaining smooth transmission).

[0064] Furthermore, the assembly of the air deflector base 42 and the mounting slot 21 creates a certain gap. This gap is designed as the mounting space 45 for the connecting rod 43, significantly reducing the overall volume occupied by the swing assembly 4. This provides more ample layout space for core components such as the evaporator and fan, aligning with the trend towards thinner and smaller designs. The connecting rod 43 is housed within the mounting space 45, making the swing assembly 4 and the mounting slot 21 a "modular whole." This integrated design reduces scattered connection points between components, not only lowering assembly complexity but also making the internal layout of the air conditioner more organized, facilitating quick identification of component relationships during later maintenance.

[0065] In some embodiments of this application, the receiving groove 22 is a through groove, the motor 44 is provided with an ear plate, the motor 44 is placed in the receiving groove 22 from the side of the base 2 away from the air duct 3, the ear plate abuts against the side of the base 2 away from the outer cover 1 and is fixed to the base 2 by a connector.

[0066] refer to Figure 5 , Figures 7-9 As shown, the motor 44 is installed into the receiving groove 22 from the side of the base 2 away from the air duct 3, and the position of the through-type receiving groove 22 usually corresponds to the active swing blade 41 of the swing assembly 4. After the drive shaft of the motor 44 passes through the receiving groove 22, it can directly connect with the active swing blade 41. Figure 11 As shown. This eliminates the need for an additional "transition drive shaft," shortening the power transmission path, improving transmission efficiency, and facilitating the assembly and disassembly of the active swing blades 41 and the fan shaft. Furthermore, considering that the side of the base 2 facing away from the air duct 3 is typically the "structural installation area" inside the equipment, belonging to a non-airflow core area, the space redundancy is relatively flexible. Installing the motor 44 here eliminates the need for a separate mounting cavity for the motor 44 on the air duct 3 side, significantly reducing the overall thickness occupied by the swing assembly 4 and the air duct 3, saving space.

[0067] The ear plate is rigidly fixed to the base 2 by a connector (such as a screw). Combined with the radial limit of the receiving groove 22, the motor 44 is completely locked in both the "axial" (along the drive shaft direction) and "radial" directions. Even if it runs at high frequency for a long time (the motor 44 drives the swing blade 41 to rotate back and forth), there will be no "axial movement" or "radial wobbling", which completely eliminates abnormal noise or transmission failure caused by loosening.

[0068] In some embodiments of this application, the oscillating blade 41 includes an oscillating blade body 411, an oscillating blade seat 412, and a connecting shaft 413. The oscillating blade body 411 is disposed on the side of the oscillating blade seat 412 facing the outer cover 1, and the connecting shaft 413 is disposed on the side of the oscillating blade seat 412 away from the outer cover 1. The oscillating blade seat 412 is disposed on the wind vane seat 42.

[0069] refer to Figures 4-5 , Figure 13 As shown, the blade body 411 is set on the side of the blade seat 412 facing the air outlet 12 of the air duct 3, so that it can be fully focused on the "airflow guidance design". The shape can be designed according to the needs, taking into account both function and aesthetics.

[0070] The connecting shaft 413 is located on the side of the blade seat 412 away from the air duct 3 to connect the blade body 411 and the connecting rod 43 / motor shaft 441. The connecting shaft 413 can be precisely controlled in terms of dimensional accuracy to ensure that the clearance between it and the shaft hole of the connecting rod 43 / fan shaft is extremely small, avoiding displacement deviation during transmission and ensuring synchronous linkage between the blade body 411 and the drive mechanism.

[0071] The blade holder 412 acts as an "intermediate bridge," integrating the blade body 411 (airflow function) and the connecting shaft 413 (transmission function) into a complete blade 41 unit, avoiding positioning confusion caused by direct assembly of the three components. Furthermore, the blade holder 412 and the fan plate holder 42 are positioned together to ensure the accurate installation position of the blade 41, thereby guaranteeing the connection with the connecting rod 43 / fan.

[0072] The connecting shaft 413 has a polygonal shaft hole structure, and the motor 44 has a polygonal motor shaft 441, wherein the connecting shaft 413 of one of the oscillating blades 41 is drivenly connected to the motor shaft 441.

[0073] like Figure 11 As shown, the fit between the polygonal shaft and the shaft hole has a "unique fitting angle" (e.g., a regular hexagon has only 6 alignment angles, and a square has only 4). During assembly, there is no need to repeatedly adjust the "circumferential position." Simply align the polygonal shaft hole of the connecting shaft 413 with the polygonal outline of the motor shaft 441 for quick insertion and drive connection, avoiding misalignment and effectively improving assembly efficiency. The motor shaft 441 has a hexagonal outline and is connected to the connecting shaft 413 via a hexagonal shaft 442.

[0074] The polygonal shaft and the shaft hole form a "surface contact rigid engagement". When the motor shaft 441 rotates, its side will directly push the corresponding side of the shaft hole to drive the connecting shaft 413 to rotate, and there is no "idling and slippage". In this way, the power of the motor 44 can be 100% transmitted to the swing blade 41, realizing a precise response that "the swing blade 41 rotates synchronously by the same angle as the motor 44 rotates".

[0075] In addition, when removing the air deflector seat 42, the drive relationship can be separated simply by pulling out the connecting shaft 413 along the axial direction. There is no damage to parts during the disassembly and assembly process, ensuring that the original transmission accuracy can still be maintained after maintenance.

[0076] In some embodiments of this application, a crank 414 is provided on the side wall of the connecting shaft 413, and a swing arm 415 is provided on the crank 414. The swing blade 41 is linked to the connecting rod 43 through the swing arm 415.

[0077] refer to Figure 12 and Figure 13 As shown, the side wall of the connecting shaft 413 is provided with two opposing cranks 414, one of which has a rocker arm 415 so that the rocker arm 415 is hinged to the shaft hole of the connecting rod 43. When the motor 44 drives the connecting shaft 413 of the active oscillating blade 41 to rotate, the crank 414 on the connecting shaft 413 will move synchronously, and the rocker arm 415 of the crank 414 will move accordingly. Through the linkage between the connecting rod 43 and all the rocker arms 415, the rocker arms 415 of all the oscillating blades 41 can be linked, ultimately driving all the oscillating blades 41 to rotate synchronously, realizing the core function of "single motor 44 driving multiple oscillating blades 41".

[0078] In some embodiments of this application, the sidewall of the connecting shaft 413 is provided with two opposing cranks 414, and the wind vane seat 42 is formed with a limiting hole 424. The cross-sectional shape of the connecting shaft 413 and its cranks 414 is adapted to the shape of the limiting hole 424 so that the connecting shaft 413 can pass through the wind vane seat 42.

[0079] refer to Figure 5 , Figure 12 and Figure 13 As shown, the cross-sectional shape of the connecting shaft 413 and its crank 414 forms a straight structure, and the corresponding limiting hole 424 is also straight, matching it. When the blade 41 is installed on the wind vane seat 42, the connecting shaft 413 passes through the limiting hole 424 to the side of the wind vane seat 42 away from the air duct 3, and then rotates relative to the wind vane seat 42 by a certain angle (such as rotating 90 degrees), so that the crank 414 and the limiting hole 424 are misaligned. This not only limits the fit between the connecting shaft 413 and the wind vane seat 42, but also rotates the connecting shaft 413 to a suitable position to connect with the connecting rod 43, and causes the blade body 411 to swing to the initial position.

[0080] In some embodiments of this application, the base 2 is provided with two mounting slots 21, and there are two swing components 4, which are respectively disposed in the two mounting slots 21.

[0081] refer to Figures 4-5 As shown, the left and right air deflector seats 42 of the air outlet 12 of the base 2 have the same structure and are each driven by a motor 44 to realize the zoned air supply of multiple swing blades 41 on the left and right air deflector seats 42.
