[0010] Figure 1 is a structural schematic diagram according to some embodiments of the present disclosure, and Figure 2 is an exploded view according to some embodiments of the present disclosure.

[0011] 1-3 , the air conditioning indoor unit according to the present disclosure includes a base body 1, a cover 2, an upper panel 8, a fan 4, an air outlet assembly 5, a vapor deposition member 6, and an air passage member 3.

[0012] Here, an electrically controlled driving member 7 is provided on one side of the base body 1. The electrically controlled driving member 7 includes an electric control box 74, a first driving mechanism 71, a second driving mechanism 72, and a third driving mechanism 73. The fan 4 is detachably connected to the first driving mechanism 71, and the electric control box 74 is the electric control center of the indoor unit for controlling the operation of each component.

[0013] The cover 2 is provided with a first opening 21 and an intake port, and the cover 2 is disposed over the base body 1 to form a second opening 22. Specifically, the cover 2 in the present disclosure may have a rectangular parallelepiped, columnar, or cubic structure.

[0014] One end of the upper panel 8 is hinged to the upper edge of the first opening 21 to cover the first opening 21. The upper panel 8 is generally provided facing the deposition member 6 so that operations such as cleaning of the deposition member 6 can be performed when the upper panel 8 is opened. One side of the upper panel 8 is connected to the cover 2 via a shaft, and the upper panel 8 can be opened and closed via this shaft.

[0015] One end of the blow-out assembly 5 is hinged to the lower edge of the first opening 21, and can open and close the second opening 22. As shown in Figures 4 to 6, the side of the blow-out assembly 5 is provided with a plurality of first engagement members 511 that releasably engage with the edge of the cover 2 near the second opening 22.

[0016] The air passage member 3 is provided in the space formed by the cover 2 and the base body 1, and can be removed from the second opening 22. Specifically, as shown in FIG. 13 , the base body 1 in this embodiment includes a base bottom plate 11 and a base side plate 12, the air passage member 3 is removably connected to the base bottom plate 11, and the fan 4 is provided in the air passage member 3.

[0017] The vapor deposition member 6 is connected to the base body 1 and is located inside the cover 2, and the vapor deposition member 6 is installed above the fan 4. Air flows from the air intake into the air path, undergoes heat exchange through the fan 4 and the vapor deposition member 6, and is then blown out from the air outlet assembly 5.

[0018] A wall-hanging plate 9 is provided at the rear of the cover 2, and the indoor unit is fixed to the wall via the wall-hanging plate 9.

[0019] Based on the above-described disassembly-possible air conditioning indoor unit, the entire electrically controlled drive member 7 is mounted on the base body 1, and correspondingly, the power lines connected to the electrically controlled drive member 7, the electric wires for each electrical load member, and the connecting signal lines are all mounted on the base body 1. Furthermore, the air passage member 3 is detachable from the base body 1, the fan 4 is detachable from the first drive mechanism 71, and the lower panel 51 is detachable from the cover 2. Thus, during disassembly and cleaning, the air outlet assembly 5, the air passage member 3, and the fan 4 can be removed and cleaned through the second opening 22, while the electrically controlled drive member 7 and other electrically charged members can be left in the base body 1, thereby avoiding the need to remove and clean the electrically charged members along with the components being removed and cleaned, thereby ensuring safety during the removal process. Furthermore, because the removed air outlet assembly 5, the air passage member 3, and the fan 4 do not contain electrically charged members, users can thoroughly clean them directly with water or other methods during cleaning, which is relatively convenient and allows users to clean them themselves, eliminating the need to hire a professional to remove and install them.

[0020] FIG. 4 is a structural schematic diagram of a blower assembly according to some embodiments of the present disclosure. As shown in FIGS. 3 and 4, one end of the blower assembly 5 is further provided with a row of a plurality of engaging claws 512, and the number of engaging claws 512 may be three. Each of the engaging claws 512 has an arc-shaped locking groove 512a, and a plurality of engaging shafts 513 are provided on the top of the cover 2, each engaging shaft 513 being locked into the arc-shaped locking groove 512a, and the arc-shaped locking grooves 512a are rotatable around the axis of the engaging shaft 513. Specifically, when installing or removing the blower assembly 5, an operator rotates the blower assembly 5 around the engaging shaft 513 so that the blower assembly 5 opens or closes the second opening 22. After rotating and opening the upper panel 8, the operator can disengage the engaging claws 512 from the engaging shaft 513, thereby removing the blower assembly 5.

[0021] Specifically, the engaging claw 512 of the present disclosure includes a first arc-shaped claw 512b and a second arc-shaped claw 512c, and the first arc-shaped claw 512b and the second arc-shaped claw 512c are smoothly connected to form an arc-shaped locking groove 512a with an opening, and the arc-shaped locking groove 512a is detachably and rotatably engaged with the engaging shaft 513. In the embodiment of the present disclosure, the first arc-shaped claw 512b and the second arc-shaped claw 512c are integrally processed and molded.

[0022] In some embodiments of the present disclosure, the front of the blow-out assembly 5 and the front of the cover 2 can be connected via other pivotal connection structures such as a hinge, which is detachably connected to the blow-out assembly 5 and the cover 2, thereby achieving the purpose of pivotally connecting the blow-out assembly 5 and the cover 2.

[0023] FIG. 5 is a structural schematic diagram of some embodiments of the present disclosure with the wall-hanging plate and base removed. FIG. 6 is an enlarged view of portion A in FIG. 5. As shown in FIGS. 4-6, in the embodiments of the present disclosure, two first engagement members 511 may be provided. The first engagement member 511 extends upward from the blower assembly 5, and a first protrusion 511a is integrally connected to one end of the first engagement member 511 away from the blower assembly 5. The cover 2 has a groove 23 that engages with the first engagement member 511, i.e., the groove 23 is for inserting the first engagement member 511 and engaging the first protrusion 511a. Specifically, the blower assembly 5 has a first engagement member 511 on each of its opposing sides, and the cover 2 has a groove 23 on each of its opposing sides. The first engagement member 511 fixedly connects the side of the blower assembly 5 to the cover 2, preventing the side of the blower assembly 5 from loosening.

[0024] Furthermore, a plurality of locking hooks 514 that detachably engage with the air passage member 3 are provided on the front portion of the blow-out assembly 5, and the connection between the locking hooks 514 and the air passage member 3 limits the relative displacement between the blow-out assembly 5 and the air passage member 3. Furthermore, a plurality of second locking members 515 that detachably engage with the air passage member 3 are further provided on the front portion of the blow-out assembly 5, and the front portion of the blow-out assembly 5 is fixed in position to the air passage member 3 by the second locking members 515 of the blow-out assembly 5 engaging with the air passage member 3.

[0025] 7 is a structural schematic diagram of an air passage member according to some embodiments of the present disclosure. As shown in FIGS. 4 and 7, the locking hook 514 is specifically plate-shaped. The width of one end of the locking hook 514 is smaller than the width of the other end of the locking hook 514. A locking groove 514a is formed at the end of the locking hook 514, and the air passage member 3 is provided with a locking block 31 that fits into and locks into the locking groove 514a. The locking block 31 corresponds to the locking groove 514a. When the second opening 22 is closed, the locking hook 514 engages with the locking block 31 of the air passage member 3, thereby locking the air outlet assembly 5 and the air passage member 3 together.

[0026] In some embodiments of the present disclosure, there may be two second engagement members 515. The second engagement member 515 first extends from the surface of the blower assembly 5 in a direction perpendicular to the blower assembly 5, and then extends obliquely rearward. A second protrusion 515a extending forward is integrally connected to the end of the second engagement member 515 away from the blower assembly 5. Here, a slot 32 is provided in the front part of the air passage member 3, and the second engagement member 515 is inserted into the slot 32, and the second protrusion 515a engages with the outer wall of the slot, thereby engaging the second engagement member 515 within the slot. This limits the displacement of the front part of the blower assembly 5.

[0027] Furthermore, a plurality of third engagement members 516 are provided at the rear of the blower assembly 5 to detachably engage with the air passage member 3, and the number of third engagement members 516 may specifically be two. The third engagement members 516 are disposed at a central position at the rear of the blower assembly 5 to fix the rear of the blower assembly 5 to the air passage member 3, thereby preventing the rear of the blower assembly 5 from moving or shaking.

[0028] Here, an arch groove 516a is provided in the third engagement member 516, and an arch body 33 that is inserted into the arch groove 516a is provided in the air passage member 3. Specifically, when installing, the air outlet assembly 5 is positioned by inserting the arch body 33 into the arch groove 516a.

[0029] The above-described first engaging member 511, second engaging member 515, and third engaging member 516 restrict the positions of the blower assembly and cover 2, and the positions of the blower assembly and air passage member 3, and the above-described connection achieves the purpose of making the cover 2 and air passage member 3 detachable from the blower assembly 5, preventing the blower assembly 5 from falling off. While the conventional technology connects the blower assembly 5 to the cover 2 and air passage member 3 with bolts, the present disclosure has the advantages of easy attachment and detachment of the blower assembly 5, preventing the blower assembly from slipping, and providing a reliable connection.

[0030] Here, in order to position and accurately attach the blower assembly 5, a first stopper block 517 is further provided at the rear of the blower assembly 5, and there may be two first stopper blocks 517. When the blower assembly 5 is placed over the second opening 22, the blower assembly 5 engages with the base body 1 via the first stopper block 517, thereby fixing the blower assembly 5 to the cover 2 and the air passage member 3 and determining the positions of the blower assembly 5 and the base body 1.

[0031] 4 and 6, second stopper blocks 518 for engaging with the cover 2 are provided at each of the two corners at the rear of the blower assembly 5, and when the blower assembly 5 is placed over the second opening 22, the second stopper blocks 518 further facilitate the fixed connection between the blower assembly 5 and the cover 2. Specifically, a lightening groove is provided at the end of the second stopper block 518 away from the upper panel 8. This is advantageous for reducing the overall weight of the blower assembly 5, facilitating installation and removal, and reducing the cost of raw materials.

[0032] In this embodiment, in order to make it easier to remove the air passage member 3 from the second opening 22 after removing the air outlet assembly 5, a finger groove 519 extending toward the inside of the air outlet assembly 5 is further provided on the side edge of the air outlet assembly 5. In other embodiments, a hook or a finger boss may be provided to make it easier for an operator to operate the air outlet assembly 5 and open the second opening.

[0033] Furthermore, in order to improve the strength and aesthetics of the blow-out assembly 5, the engaging claw 512, the first engaging member 511, the second engaging member 515, the third engaging member 516, the locking hook 514, the first stopper block 517, and the second stopper block 518 in the blow-out assembly 5 are all processed and molded integrally with the blow-out assembly 5.

[0034] 2-4, the air outlet assembly 5 in this embodiment includes a lower panel 51, a wind guide plate 52, and a link mechanism 53. One side of the upper panel 8 is connected to the cover 2 via a pivot shaft, allowing the upper panel 8 to be opened and closed via the pivot shaft. To ensure the stability of the connection between the upper panel 8, the lower panel 51, and the cover 2, a locking structure is provided on the other end of the upper panel 8. This locking structure passes through a recess in the upper end of the lower panel 51 and engages with a locking hole structure in the cover 2 to secure the upper panel 8, making it easy to attach and detach the upper panel 8.

[0035] Here, the lower panel 51 is provided with an air outlet 520, and the air outlet 520 is provided with a rotatable air guide plate 52 for opening and closing the air outlet 520.

[0036] Fig. 11 is a structural schematic diagram of an assembly of an air passage member and a base body according to some embodiments of the present disclosure. Fig. 12 is a partial structural schematic diagram of an assembly of an air passage member and a base body according to some embodiments of the present disclosure. Fig. 13 is a structural schematic diagram of a base body according to some embodiments of the present disclosure. As shown in Figs. 11-13, a removal passage for removing the air passage member 3 is provided in the base body 1, and a third drive mechanism 73 is provided on the outer surface of the base side plate 12. The output shaft of the third drive mechanism 73 penetrates the base side plate 12 and is removably connected to the air guide plate 52, and the end of the output shaft of the third drive mechanism 73 is located at the outer edge of the removal passage. Because the removal passage for air passage member 3 is located on base body 1, third drive mechanism 73 is located on the outer surface of base side plate 12, and the end of the output shaft of third drive mechanism 73, which is removably connected to air guide plate 52, is located on the outer edge of the removal passage, when air passage member 3 is removed through the removal passage, there is no need to remove third drive mechanism 73; air passage member 3 can be removed by simply releasing the connection between third drive mechanism 73 and air guide plate 52. This avoids safety concerns caused by the attachment portion of third drive mechanism 73 becoming loose or deformed due to multiple attachments and detachments, and makes it easier to attach and detach air passage member 3.

[0037] Furthermore, a motor mounting fixture 13 is provided on the outer surface of the base side plate 12, and the mounting position of the motor mounting fixture 13 completely avoids the removal passage of the air passage member 3. A housing cavity for the third drive mechanism 73 is provided in the motor mounting fixture 13, and the third drive mechanism 73 is mounted within the housing cavity. Since the motor mounting fixture 13 avoids the mounting cavity 15 and the removal passage, the third drive mechanism 73 also avoids the removal passage.

[0038] Specifically, the motor mounting fixture 13 includes a motor mounting plate 131 and a surrounding plate 132 attached to the edge of the motor mounting plate. The motor mounting plate 131 is fixed to an end of the base body 1, and the motor mounting plate 131 and the surrounding plate 132 form an accommodating cavity. The motor mounting plate 131 and the surrounding plate 132 may be integrally molded or may be fixedly connected by adhesive or bolts. In this embodiment, the motor mounting plate 131 is fixed perpendicular to the surrounding plate 132 and is integrally molded.

[0039] In some embodiments of the present disclosure, depending on the usage requirements of the base body 1, one base side plate 12 may be provided at each end of the base body 1, which are a first base side plate 12a and a second base side plate 12b, respectively. The base bottom plate 11 may be integrally formed with the first base side plate 12a and the second base side plate 12b or may be fixed to them by bolts. The base bottom plate 11, the first base side plate 12a, and the second base side plate 12b form a mounting cavity 15 for the air passage member 3, and a removal passage is located at the front of the base body 1, and a motor mounting plate 131 is provided on the front side edge of one of the base side plates 12.

[0040] Furthermore, the base side plate 12 may specifically be a triangular plate. The motor mounting plate 131 is connected to one side of the triangular plate away from the removal passage and extends in that direction. Specifically, the base side plate 12 is perpendicular to the base bottom plate 11, and the motor mounting plate 131 is flush with the base side plate 12. In the embodiment of the present disclosure, the motor mounting plate 131 is injection molded integrally with the base side plate 12, thereby increasing the connection strength between the motor mounting plate 131 and the base and preventing loosening.

[0041] Here, in order to accommodate different sizes of third drive mechanisms 73, the width of the motor mounting plate 131 increases and then decreases from the front to the rear, so that the width of the storage cavity increases and then decreases from the front to the rear.

[0042] A through hole 131a is provided in the motor mounting plate 131 in the accommodation cavity for the output shaft of the third drive mechanism 73 to pass through, and the output shaft is removably connected to the air guide plate 52 after passing through the motor mounting plate 131, and the end of the output shaft of the third drive mechanism 73 is located outside the removal passage, so that when the connection between the output shaft of the third drive mechanism 73 and the air guide plate 52 is released, the air path member 3 can be removed without having to remove the third drive mechanism 73.

[0043] A plurality of reinforcing ribs 131b are integrally formed on the motor mounting plate 131 in a net-like pattern to increase the strength of the motor mounting plate 131, and bosses 131c are provided at the intersections of the reinforcing ribs 131b. First mounting holes 131d are provided in the bosses 131c, and the first mounting holes 131d are connected to the third drive mechanism 73 via fasteners.

[0044] As shown in Figure 13, the front end of the base bottom plate 11 extends downward to form a connection part 111, and a piping space 112 is formed between the base bottom plate 11 and the connection part 111. In conventional technology, the piping assembly is directly bent at a certain angle to retract in order to remove the air passage member 3, but in this way the piping assembly of the indoor unit is placed directly in this piping space 112 and can be separated from the air passage member 3 via the base bottom plate 11. This effectively prevents the connecting piping from interfering with the air passage member 3 during the installation and removal process of the air passage member 3, and also prevents damage to the connecting piping by the air passage member 3 during the installation and removal process, ensuring smooth removal of the air passage member 3.

[0045] Furthermore, an anti-static shaft is provided at the portion where the output shaft of the third drive mechanism 73 passes through the through-hole 131a.

[0046] FIG. 14 is a structural schematic diagram of an assembly of a second link and an air guide blade according to several embodiments of the present disclosure. As shown in FIGS. 3 and 13-15, link mechanism 53 is provided in air outlet 520 and guides the air outlet 520 in an air-outlet direction. Link mechanism 53 includes a first link 531 and a second link 532 that are detachably connected. A plurality of air guide blades 533 are provided at intervals on first link 531. A second drive mechanism 72 is provided at one end of base body 1. Second link 532 extends outside air passage member 3 and is rotatably connected to the output shaft of second drive mechanism 72. As shown in FIGS. 8 to 10, air passage member 3 is provided with an opening groove 34 through which second link 532 passes.

[0047] Specifically, first link 531 is provided horizontally on lower panel 51 of air outlet 520, and second drive mechanism 72 is linked to rotate first link 531 via second link 532, thereby swinging air guide blade 533 to adjust the air outlet direction of air outlet 520. Lower panel 51 is also covered by opening groove 34, which is a rectangular groove or an arc-shaped groove. When removing air passage member 3 for cleaning, lower panel 51 is opened, the connection between first link 531 and second link 532 is released, and second link 532 is rotated to pull out second link 532 from inside opening groove 34 and rotate it to the outside of air passage member 3, thereby enabling removal of air passage member 3, without the need to remove second drive mechanism 72. This avoids safety concerns that may arise from the attachment portion of the second drive mechanism 72 becoming loose or deforming due to multiple attachments and detachments, and also makes it possible to easily attach and detach the air passage member 3.

[0048] During the disassembly process of the disassembly and washable air conditioning indoor unit according to this embodiment, the lower panel 51 is positioned vertically so as to be attached to the air passage member 3, and the arrangement of the opening groove 34 is advantageous for allowing the second link 532 to escape in the air passage member 3, preventing the second link 532 from increasing the gap between the lower panel 51 and the air passage member 3, and utilizing the opening groove 34 further improves the compactness of the attachment between the lower panel 51 and the air passage member 3.

[0049] Specifically, as shown in FIGS. 14-15 , an end of the first link is provided with an elastic stop 531a, and an end of the second link 532 is provided with a hooking groove 532a for removably hooking the elastic stop 531a. The elastic stop 531a is specifically a rubber elastic hook, which may be integrally molded with the first link 531. The hooking groove 532a includes a stop block with an inlet 532b and a hook block with a through-slot 532c extending vertically. The stop block, the hooking block, and the second link 532 are integrally molded, and the inlet 532b communicates with the through-slot 532c. The elastic hook can be inserted through the inlet 532b and then engaged in the through-slot 532c to connect the first link 531 and the second link 532. When removal is required, the elastic hook is compressed to reduce its volume, and the elastic hook is sequentially removed from the through-slot 532c and the inlet 532b, thereby separating the first link 531 and the second link 532.

[0050] 15, the second link 532 includes a first link portion 532d, a second link portion 532e, and a third link portion 532f, which are arranged in sequence. The first link portion 532d is arranged parallel to the third link portion 532f, and the second link portion 532e is fixed perpendicular to the first link portion 532d and the third link portion 532f. The latch groove 532a is provided at an end of the first link portion 532d away from the second link portion 532e, and the dimensions of the first link portion 532d are aligned with the opening groove 34. In other embodiments of the present disclosure, the shape of the second link may be other shapes so that the second drive mechanism 72 can be easily attached and coupled to an appropriate position on the base body 1.

[0051] Specifically, second drive mechanism 72 includes a link drive motor 721 and a crank structure 722. An output end of link drive motor 721 is connected to one end of crank structure 722, and the other end of the crank structure is rotatably connected to a second end of second link 532. Link drive motor 721 rotates crank structure 722, thereby enabling link mechanism 53 to swing air guide blade 533 along with it. Furthermore, when first link 531 and second link 532 are disconnected, second link 532 can rotate around crank structure 722, thereby rotating its first end out of air passage member 3 and avoiding interference with the removal passage of air passage member 3.

[0052] 2, the air guide plate 52 in this embodiment includes a first horizontal air guide plate 521 and a second horizontal air guide plate 522. The third drive mechanism 73 includes a first horizontal drive motor 731 and a second horizontal drive motor 732. The first horizontal drive motor 731 is detachably connected to one end of the first horizontal air guide plate 521, and the second horizontal drive motor 732 is detachably connected to one end of the second horizontal air guide plate 522. Specifically, one end of each of the first horizontal air guide plate 521 and the second horizontal air guide plate 522 is rotatably connected to the lower panel 51, and a second bushing is provided at the other end. The first lateral drive motor 731 and the second lateral drive motor 732 each have a second motor shaft inserted into a second bushing, and the first lateral air guide plate 521 is inserted into the first lateral drive motor 731, and the second lateral air guide plate 522 is inserted into the second lateral drive motor 732 via a second bushing. In this embodiment, the first lateral air guide plate 521 and the second lateral air guide plate 522 are driven to swing by different drive motors to change the blowing direction of the air outlet 520, thereby realizing independent operation of the two lateral air guide plates and meeting different user needs.

[0053] FIG. 9 is a structural schematic diagram of an air passage member according to some embodiments of the present disclosure, viewed from another perspective. FIG. 10 is an enlarged view of portion B in FIG. 9. FIG. 15 is a structural schematic diagram of a connection between a first link and a third drive mechanism according to some embodiments of the present disclosure. FIG. 16 is a structural schematic diagram of a locking member according to some embodiments of the present disclosure. FIG. 17 is a partial structural schematic diagram of a base body according to some embodiments of the present disclosure, viewed from another perspective. As shown in FIGS. 9-10 and 13-17, an air passage is formed within the air passage member 3. Locking members 35 are movably provided on both sides of the air passage member 3. The base body 1 is provided with locking grooves 14 corresponding to the locking members 35. The locking members 35 can be locked to the base body 1 by rotating and locking into the locking grooves 14. The locking members 35 can be released from the locking grooves 14 to lock the air passage member 3 to the base body 1. After the air passage member 3 is attached to the desired position in the mounting cavity 15 of the base body 1, the locking member 35 of the air passage member 3 and the locking groove 14 of the base body 1 are used to lock or unlock the air passage member 3 and the base body 1. This operation is simple. In this embodiment, the locking groove 14 is provided on the base bottom plate 11, and the locking member 35 can be rotated downward to lock with the locking groove 14 or rotated upward to disengage from the locking groove 14 and unlock, thereby locking the air passage member 3 in the vertical direction. The first base side plate 12a and the second base side plate 12b can limit the attachment position of the air passage member 3 in the horizontal direction. To ensure stable attachment of the air passage member 3, the connection portion 111 of the base body 1 is further provided with a locking groove 111a. The lower end of the air passage member 3 is provided with a plurality of locking devices 36 that engage with the locking groove 111a, thereby locking the air passage member 3 in the front-to-rear direction. This further locks the air passage member 3 to the base body 1 and prevents them from separating. Specifically, as shown in FIG. 7, second mounting holes 310 are provided on both sides of the air passage member 3, and as shown in FIG. 16, the locking member 35 includes a main body 351 that can be partially inserted into the locking groove 14, one end of the main body 351 is provided with a connecting shaft 352 for assembly into the second mounting hole 310, and the other end of the main body 351 is provided with a toggle portion 353.Specifically, by rotating the connecting shaft 352 with the toggle portion 353, a part of the main body 351 is inserted into the locking groove 14 in the lower base bottom plate 11, thereby locking the air passage member 3 to the base body 1.

[0054] Furthermore, to ensure stability during the installation of the air passage member 3, a first position restricting structure 121 and a second position restricting structure 122 are provided on the inside of the first base side plate 12a and the inside of the second base side plate 12b, as shown in Fig. 13, and a first mating portion that mates with the first position restricting structure 121 and a second mating portion 37 that mates with the second position restricting structure 122 are provided at the rear end of the air passage member 3 (as shown in Fig. 7), respectively, ensuring the accuracy of the installation position of the air passage member 3 via the first position restricting structure 121 and the second position restricting structure 122 and further ensuring the quality of the installation. Generally, guide surfaces are provided at the bottom ends of the first position restricting structure 121 and the second position restricting structure 122, so that the front end of the air passage member 3 is guided along these guide surfaces when the air passage member 3 is installed, ensuring the quality of the installation.

[0055] Specifically, as shown in FIG. 17, the second position restriction structure 122 has a second guide surface 122a extending in the vertical direction, and the second mating portion 37 has a third guide surface 371 extending in the vertical direction, the second guide surface 122a sliding in line with the third guide surface 371, and in the process of attaching or detaching the air passage member 3 to or from the base body 1, the second guide surface 122a guides and slides the third guide surface 371, and in the process of attaching or detaching the air passage member 3, it directly guides the movement of the air passage member 3 in accordance with the attachment or detachment, eliminating the need for the worker to estimate the distance in the left-right direction and positioning it, making removal easy, and eliminating the need for repeated trial and error and adjustments, allowing for easy positioning and installation, improving the efficiency of attachment and detachment.

[0056] FIG. 18 is a structural schematic diagram of an assembly of an air passage member and a fan according to some embodiments of the present disclosure, from another perspective. FIG. 19 is an enlarged view of portion C in FIG. 18. FIG. 20 is a structural schematic diagram of an assembly of a fan and a first drive mechanism according to some embodiments of the present disclosure. FIG. 21 is an enlarged view of portion D in FIG. 20. FIG. 22 is a structural schematic diagram of a third drive mechanism according to some embodiments of the present disclosure. As shown in FIGS. 1 and 18-22, the first drive mechanism 71 in this embodiment includes a fan motor 711. The fan motor 711 has a first motor shaft 712. One end of the fan 4 is connected to one side of the air passage member 3 via a bearing seat assembly 320 (as shown in FIG. 8). The other end of the fan 4 is provided with a first bushing 41 that is movably inserted into the first motor shaft 712. A stopper 713 is provided on the first motor shaft 712, and a lock screw 42 for locking the first motor shaft 712 is provided on the first bushing 41, and the lock screw 42 is disposed radially therearound. After removing the lock screw 42, the fan 4 is retracted a certain distance along its axial direction toward the bearing seat assembly 320, and the first bushing 41 is released from the first motor shaft 712. The fan 4 can then be removed from the fan motor 711. To assemble the fan, the first bushing 41 of the fan 4 is directly inserted onto the first motor shaft 712, and the lock screw 42 is tightened when the stopper 713 abuts against the end of the first bushing 41. The stopper 713 and the lock screw 42 limit the axial and radial position of the fan 4, ensuring stability during operation of the fan 4. To prevent localized protrusions on the surface of the first motor shaft 712 caused by the lock screw 42 being locked onto the first motor shaft 712, which could affect assembly, an annular groove 712a is formed on the first motor shaft 712 in this embodiment. When the lock screw 42 is locked, the lower end surface of the lock screw 42 abuts against the annular groove 712a to prevent localized protrusions from occurring on the first motor shaft 712. Alternatively, the first motor shaft 712 may be configured as a step shaft, and the first bushing 41 may be configured as a corresponding step hole.When the first bushing 41 and the first motor shaft 712 are assembled, the small diameter portion of the first motor shaft 712 fits into the large diameter portion of the stepped hole of the first bushing 41, forming a gap. When the lock screw 42 is locked, the lower end face of the lock screw 42 directly abuts against this gap, which also has the effect of preventing the formation of localized protrusions.

[0057] In the prior art, slots in the blades of the fan 4 allow insertion of a removal tool to facilitate removal of the lock screw 42 of the fan 4. In this embodiment, as shown in FIG. 19 , a removal hole 39 is provided at the front end of the air passage member 3 to facilitate removal of the lock screw 42 of the fan 4. When the lock screw 42 is locked to the first motor shaft 712, the removal hole 39 is radially opposite the lock screw 42. When a user removes the fan 4, they first remove the air outlet assembly 5, rotate the fan 4, and expose the lock screw 42 in the removal hole 39. Then, they can insert a removal tool through the removal hole 39 of the air passage member 3 to remove the lock screw 42. Compared to removing the fan 4 from the blades, in this embodiment, the removal hole 39 is provided at the front end of the air passage member 3, which provides more space and makes the operation easier.

[0058] In the specific removal process, first, the upper panel 8 is removed from the cover 2 to prevent the lower end of the upper panel from interfering with the opening of the second opening 22 due to the rotation of the lower panel 51. Next, the first lateral air guide plate 521 and the second lateral air guide plate 522 are unlocked from the first lateral drive motor 731 and the second lateral drive motor 732, respectively, the elastic stopper 531a between the first link 531 and the second link 532 is unlocked, and the second stopper block 518, the third engagement member 516, and the first stopper 517 of the lower panel 51 are all loosened. Then, the lower panel 51 is lifted to make the opening of the engagement claw 512 flush with the engagement shaft 513, and the engagement claw 512 is disengaged from the engagement shaft 513 through the opening. This removes the lower panel 51 from the cover 2, and the second link 532 is rotated so that its first end passes through the opening groove 34 and rotates outward from the air passage member 3. Then, a tool is used to remove the lock screw 42 locked to the first motor shaft 712 through the removal hole 39, and the fan 4 is retracted a certain distance along its axial direction toward the bearing seat assembly 320, thereby separating the first bushing 41 from the first motor shaft 712 and removing the fan 4 from the fan motor 711. After removal, the fan 4 is left inside the air passage member 3, and finally, the lock member 35 is rotated upward to remove it from the lock groove 14, and the air passage member 3 together with the fan 4 can be extracted from the mounting cavity 15 of the base body 1.

[0059] In the air conditioning indoor unit that can be disassembled and cleaned according to some embodiments of the present disclosure, the entire electrically controlled drive member 7 is mounted on the base body 1, the air passage member 3 is removable from the base body 1, the fan 4 is removable from the first drive mechanism 71, the lower panel 51 is removable from the cover 2, and the first link 531 is removable from the second link 532, and the first end of the second link 532 can be rotated to the outside of the air passage member 3 through the opening groove 34, thereby allowing the first link 531 to be removed from the second drive mechanism 72 and at the same time avoiding the removal passage for the air passage member 3, and also allowing the lower panel 51 to be removed from the cover 2. In this way, when disassembling and cleaning, the air outlet assembly 5, air passage member 3, and fan 4 can be removed through the second opening 22 for cleaning, with all electrically charged members such as the electrically controlled drive member 7 remaining in the base body 1. This avoids removing the electrically charged members together with the parts to be disassembled and cleaned, ensuring safety during the removal process. Furthermore, because the removed air outlet assembly 5, air passage member 3, and fan 4 do not contain electrically charged members, the user can thoroughly clean them directly by rinsing them with water, for example. This operation is relatively convenient, and the user can clean them themselves without having to ask a professional to install and remove them.
