The entire disclosure of which is incorporated by reference into the present disclosure.

This disclosure relates to the field of air conditioning technology, and in particular to an air conditioning indoor unit that can be disassembled and cleaned.

Conventionally, an air outlet assembly for an air conditioning indoor unit generally includes a panel and a vertical air guide plate attached to the panel, and the panel needs to be connected to the cover of the air conditioning indoor unit. In the conventional technology, the panel and the cover are generally either molded as one unit and fixed, or removably connected by bolts. When the panel and the cover are molded as one unit, it is difficult to remove the panel. When connected by bolts, the panel needs to be removed multiple times because the panel removal process is complicated and the fan assembly and air passage members of the air conditioning indoor unit need to be periodically removed and cleaned. Multiple attachment and removal of the bolts tends to reduce the connection stability of the bolts, causing the threads of the bolts to be crushed or fall off, resulting in an unstable connection between the air outlet assembly and the cover.

The air conditioning indoor unit to be disassembled and cleaned according to the present disclosure is:
A base body;
a cover having a first opening and covering the base body to form a second opening;
an upper panel having one end hinged to an upper edge of the first opening to cover the first opening;
a blowing assembly having one end hinged to a lower edge of the first opening and capable of opening and closing the second opening;
A side edge of the blower assembly is provided with a plurality of first engagement members for releasably engaging with a cover on a side edge of the second opening.

4 is a structural schematic diagram of a blowing assembly according to some embodiments of the present disclosure. As shown in FIG. 3 and FIG. 4, a row of multiple engagement claws 512 is provided at one end of the blowing assembly 5, and the number of engagement claws 512 may be three. Each of the engagement claws 512 has an arc-shaped locking groove 512a, and a plurality of engagement shafts 513 are provided at the top of the cover 2, and each engagement shaft 513 is locked in the arc-shaped locking groove 512a, and the arc-shaped locking groove 512a can rotate around the axis of the engagement shaft 513. Specifically, when attaching and detaching, the operator rotates the blowing assembly 5 around the engagement shaft 513 so that the blowing assembly 5 opens and closes the second opening 22, and after rotating and opening the upper panel 8, the operator can disengage the engagement claws 512 from the engagement shaft 513, thereby removing the blowing assembly 5.

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 engaging groove 512a having an opening, and the arc-shaped engaging 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.

In some embodiments of the present disclosure, the front of the blowing assembly 5 and the front of the cover 2 can be connected via other pivotal connection structures, such as hinges, which are removably connected to the blowing assembly 5 and the cover 2, thereby achieving the purpose of pivotally connecting the blowing assembly 5 to the cover 2.

5 is a structural schematic diagram of some embodiments of the present disclosure with the wall hanging plate and the base body removed. FIG. 6 is an enlarged view of part A in FIG. 5. As shown in FIG. 4-6, in the embodiments of the present disclosure, the first engagement member 511 may be specifically two. The first engagement member 511 extends upward from the blowing assembly 5, and the first protrusion 511a is integrally connected to one end of the first engagement member 511 away from the blowing assembly 5, and the cover 2 has a groove 23 that engages with the first engagement member 511, that is, the groove 23 is for inserting the first engagement member 511 and locking the first protrusion 511a. Specifically, the blowing assembly 5 has a first engagement member 511 on each of the opposing sides, and the cover 2 has a groove 23 on each of the opposing sides. The first engagement member 511 fixedly connects the side of the blowing assembly 5 to the cover 2 to prevent the side of the blowing assembly 5 from loosening.

Furthermore, the front part of the blowing assembly 5 is provided with a plurality of locking hooks 514 that removably engage with the air passage member 3, and the relative displacement between the blowing assembly 5 and the air passage member 3 is restricted by the connection between the locking hooks 514 and the air passage member 3. Furthermore, the front part of the blowing assembly 5 is further provided with a plurality of second engagement members 515 that removably engage with the air passage member 3, and the front part of the blowing assembly 5 is fixed in position to the air passage member 3 by the second engagement members 515 of the blowing assembly 5 engaging with the air passage member 3.

7 is a structural schematic diagram of an air passage member according to some embodiments of the present disclosure. As shown in FIG. 4 and FIG. 7, the locking hook 514 is specifically plate-shaped. The width of the end of the locking hook 514 is smaller than the width of the other end of the locking hook 514. A locking hook groove 514a is formed at the end of the locking hook 514, and a locking block 31 for fitting and locking with the locking hook groove 514a is provided on the air passage member 3, and the locking block 31 corresponds to the locking hook 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, thus locking the blowing assembly 5 and the air passage member 3.

In some embodiments of the present disclosure, the second engagement member 515 may be specifically two. The second engagement member 515 first extends from the surface of the blowing assembly 5 in a direction perpendicular to the blowing assembly 5, and then extends at an angle backward. A second protrusion 515a extending forward is integrally connected to the end of the second engagement member 515 away from the blowing assembly 5. Here, a slot 32 is provided at the front 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 in the slot. This limits the displacement of the front of the blowing assembly 5.

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

Here, the third engagement member 516 is provided with an arch groove 516a, and the air passage member 3 is provided with an arch body 33 that is inserted into the arch groove 516a. Specifically, when mounting, the blower assembly 5 is positioned by inserting the arch body 33 into the arch groove 516a.

The above-mentioned first engaging member 511, second engaging member 515, and third engaging member 516 restrict the positions of the blowing assembly and the cover 2, and the blowing assembly and the air passage member 3, and the above-mentioned connection achieves the purpose of making the cover 2 and the air passage member 3 removable from the blowing assembly 5, and prevents the blowing assembly 5 from falling off. Whereas in the conventional technology the blowing assembly 5 is connected to the cover 2 and the air passage member 3 by bolts, the present disclosure has the advantages that the blowing assembly 5 is easy to attach and detach, the blowing assembly is less likely to slip, and the connection is reliable.

Here, in order to position and accurately attach the blowing assembly 5, a first stopper block 517 is further provided at the rear of the blowing assembly 5, and the number of first stopper blocks 517 may be two. When the blowing assembly 5 is placed over the second opening 22, the blowing assembly 5 engages with the base body 1 via the first stopper block 517, and thus the blowing assembly 5 is fixedly connected to the cover 2 and the air passage member 3, and the positions of the blowing assembly 5 and the base body 1 are further determined.

Furthermore, as shown in Figs. 4 and 6, a second stopper block 518 for engaging with the cover 2 is provided at each of the two corners at the rear of the blowing assembly 5, and when the blowing assembly 5 is placed over the second opening 22, the second stopper block 518 further facilitates the fixed connection between the blowing 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 in reducing the overall weight of the blowing assembly 5, facilitating installation and removal, and reducing the input cost of raw materials.

In this embodiment, in order to make it easier to remove the air passage member 3 from the second opening 22 after removing the blow-out assembly 5, a finger groove 519 extending toward the inside of the blow-out assembly 5 is further provided on the side of the blow-out assembly 5. In other embodiments, a hook or a boss for finger hanging may be provided so that an operator can easily operate the blow-out assembly 5 to open the second opening.

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 integrally processed and molded with the blow-out assembly 5.

Furthermore, as shown in FIG. 2-4, the blowing 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, which allows 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, which passes through a clearance groove at 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 in place, making it easy to attach and detach the upper panel 8.

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.

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

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 avoids the removal passage.

Specifically, the motor mounting fixture 13 includes a motor mounting plate 131 and a surrounding plate 132 provided on the edge of the motor mounting plate, the motor mounting plate 131 is fixedly connected to the end of the base body 1, and the motor mounting plate 131 and the surrounding plate 132 form an accommodation cavity. Here, the motor mounting plate 131 and the surrounding plate 132 may be integrally molded, or may be fixedly connected by bonding or bolts. In this embodiment, the motor mounting plate 131 is fixed perpendicular to the surrounding plate 132 and is integrally molded.

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 is 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 fixedly formed with bolts. The base bottom plate 11, the first base side plate 12a, and the second base side plate 12b form an attachment cavity 15 for the air passage member 3, the removal passage is located at the front of the base body 1, and the motor attachment plate 131 is provided on the front side edge of one of the base side plates 12.

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 is arranged to extend 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 avoiding loosening.

Here, in order to accommodate the storage of third drive mechanisms 73 of different sizes, 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.

The motor mounting plate 131 in the housing cavity is provided with a through hole 131a through which the output shaft of the third drive mechanism 73 passes. After passing through the motor mounting plate 131, the output shaft is removably connected to the air guide plate 52, and the end of the output shaft of the third drive mechanism 73 is located outside the removal passage. When the connection between the output shaft of the third drive mechanism 73 and the air guide plate 52 is released, the air passage member 3 can be removed without the need to remove the third drive mechanism 73.

To increase the strength of the motor mounting plate 131, a plurality of reinforcing ribs 131b are integrally formed in a net-like intersecting arrangement, and bosses 131c are provided at the intersections of the reinforcing ribs 131b. A first mounting hole 131d is provided in the boss 131c, and the first mounting hole 131d is connected to the third drive mechanism 73 via a fastener.

As shown in FIG. 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 the conventional technology, the piping assembly is directly bent at a certain angle 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 avoids the connection piping from interfering with the air passage member 3 during the installation and removal process of the air passage member 3, and also avoids damage to the connection piping caused by the air passage member 3 during the installation and removal process, ensuring smooth removal of the air passage member 3.

In addition, 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.

Figure 14 is a structural schematic diagram of the assembly of the second link and the air guide blade according to some embodiments of the present disclosure. As shown in Figures 3 and 13-15, the link mechanism 53 is provided in the air outlet 520 to guide the air outlet 520 in the air outlet direction. The link mechanism 53 includes a first link 531 and a second link 532 that are removably connected, the first link 531 is provided with a plurality of air guide blades 533 spaced apart, and a second drive mechanism 72 is provided at one end of the base body 1. The second link 532 extends outside the air passage member 3 and is rotatably connected to the output shaft of the second drive mechanism 72. As shown in Figures 8 to 10, the air passage member 3 is provided with an opening groove 34 through which the second link 532 passes.

Specifically, the first link 531 is horizontally provided on the lower panel 51 of the air outlet 520, and the second drive mechanism 72 is linked to rotate the first link 531 via the second link 532, thereby swinging the air guide blade 533 to adjust the air outlet 520's air direction. The lower panel 51 is also covered by the opening groove 34, which is a rectangular groove or an arc-shaped groove. When removing the air passage member 3 for cleaning, the lower panel 51 is opened, the connection between the first link 531 and the second link 532 is released, and the second link 532 is rotated to pull out the second link 532 from the opening groove 34 and rotate it to the outside of the air passage member 3, thereby removing the air passage member 3, and there is no need to remove the second drive mechanism 72. This avoids safety concerns caused by the attachment portion of the second drive mechanism 72 loosening or deforming due to multiple attachments and detachments, and makes it easy to attach and detach the air passage member 3.

During the disassembly process of the disassembly-cleanable 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, so 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 to further improve the compactness of the attachment between the lower panel 51 and the air passage member 3.

Specifically, as shown in FIG. 14-15, an elastic stopper 531a is provided at the end of the first link, and a hook groove 532a is provided at the end of the second link 532 for removably hooking the elastic stopper 531a. The elastic stopper 531a is specifically a rubber elastic hook, and the elastic hook may be molded integrally with the first link 531. The hook groove 532a includes a stop block with an inlet 532b and a hook block having a through groove 532c extending vertically. The stop block, the hook block, and the second link 532 are molded integrally, and the inlet 532b communicates with the through groove 532c, and the elastic hook can be inserted from the inlet 532b and then engaged in the through groove 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 groove 532c and the inlet 532b to separate the first link 531 and the second link 532.

Furthermore, as shown in FIG. 15, the second link 532 includes a first link portion 532d, a second link portion 532e, and a third link portion 532f arranged in sequence. The first link portion 532d is arranged in parallel with 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 hook groove 532a is provided at an end of the first link portion 532d away from the second link portion 532e, and the size of the first link portion 532d is matched to 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 connected to an appropriate position of the base body 1.

Specifically, the second drive mechanism 72 includes a link drive motor 721 and a crank structure 722. The output end of the link drive motor 721 is connected to one end of the crank structure 722, and the other end of the crank structure is rotatably connected to the second end of the second link 532. The link drive motor 721 drives the crank structure 722 to rotate, so that the link mechanism 53 swings the air guide blade 533 along with it. In addition, when the connection between the first link 531 and the second link 532 is released, the second link 532 can rotate around the crank structure 722, and thus the first end of the second link 532 can be rotated outside the air passage member 3 to avoid interference with the removal passage of the air passage member 3.

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.

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 viewpoint. FIG. 19 is an enlarged view of part 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 part 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 FIG. 1, FIG. 18-FIG. 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), and the other end of the fan 4 is provided with a first bush 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 bush 41, and the lock screw 42 is arranged along its radial direction. In this way, after removing the lock screw 42, the fan 4 is moved a certain distance along its axial direction toward the bearing seat assembly 320, and the first bush 41 is removed from the first motor shaft 712, so that the fan 4 can be removed from the fan motor 711. Then, during assembly, the first bush 41 of the fan 4 is directly inserted into the first motor shaft 712, and the lock screw 42 is tightened when the stopper 713 abuts against the end of the first bush 41. The stopper 713 and the lock screw 42 realize the positional restriction in the axial and radial directions for the fan 4, and ensure the stability of the operation of the fan 4. In order to prevent the lock screw 42 from being locked to the first motor shaft 712, which may cause a localized protrusion on the surface of the first motor shaft 712 and affect the assembly, in this embodiment, an annular groove 712a is provided on the first motor shaft 712. When the lock screw 42 is locked, the lower end surface of the lock screw 42 abuts against the annular groove 712a, preventing localized protrusions from occurring on the first motor shaft 712. Alternatively, the first motor shaft 712 may be arranged as a step shaft, and the first bush 41 may be arranged as a corresponding step hole. When the first bush 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 step hole of the first bush 41 to form a gap, and when the lock screw 42 is locked, the lower end surface of the lock screw 42 abuts directly against the gap, which also has the effect of preventing localized protrusions from occurring.

In the prior art, a slot is provided in the blade of the fan 4 to facilitate removal of the lock screw 42 in the fan 4 by inserting a removal tool. 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 in the fan 4. When the lock screw 42 is locked to the first motor shaft 712, the removal hole 39 faces the lock screw 42 in the radial direction. When a user removes the fan 4, the user first removes the blowing assembly 5, rotates the fan 4 to expose the lock screw 42 to the removal hole 39, and then inserts 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 blade, in this embodiment, the removal hole 39 is provided at the front end of the air passage member 3, so that the space is larger and the operation is easier.

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 horizontal air guide plate 521 and the second horizontal air guide plate 522 are unlocked from the first horizontal drive motor 731 and the second horizontal drive motor 732, respectively, and 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 released from the engagement shaft 513 through the opening. The lower panel 51 is removed from the cover 2, and the second link 532 is rotated to rotate its first end through the opening groove 34 to the outside of 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 moved a certain distance along its axial direction toward the bearing seat assembly 320, thereby removing the first bush 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 is extracted from the mounting cavity 15 of the base body 1.

In the air conditioning indoor unit which can be disassembled and cleaned according to some embodiments of the present disclosure, the entire electrically controlled drive member 7 is provided 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 via the opening groove 34, thereby making it possible to remove the first link 531 from the second drive mechanism 72 while at the same time avoiding a removal passage for the air passage member 3, and also making the lower panel 51 removable from the cover 2. In this way, when disassembling and cleaning, the blowing assembly 5, air passage member 3, and fan 4 can be removed from the second opening 22 and cleaned, and all charged members such as the electrically controlled driving member 7 are left on the base body 1, which avoids removing the charged members together with the disassembling and cleaning members and ensures the safety of the removal process. In addition, since the removed blowing assembly 5, air passage member 3, and fan 4 do not have charged members, the user can thoroughly clean them directly by washing them with water during cleaning, which is relatively convenient, and the user can clean them by themselves, without having to ask a professional to install and remove them.
