Description

Technical Field

[0001] The invention relates to air outlet control technology for air conditioners, and in particular to a detachable air guide device and an air conditioner thereof. Background Art

[0002] At present, after long-term use, dust is easily accumulated in the internal air duct cavity of the split air conditioner indoor unit. If it is not effectively cleaned, bacteria will breed, causing the air flow blown out of the indoor unit's air outlet to have an odor and even make people sick.

[0003] In the prior art, the air guide mechanism of the air outlet of the indoor unit of a household cross-flow split air conditioner is mainly divided into a detachable air guide mechanism and a non-detachable air guide mechanism. The installation method of the upper and lower air outlet baffles, left and right air sweeping blades and air duct volute tongue of the air conditioner corresponding to the non-detachable air guide mechanism is relatively complicated, which makes it difficult for users to effectively clean the air outlet assembly and the inside of the air duct, greatly affecting the air supply health of the air conditioner and the user's comfortable experience.

[0004] The detachable air guide mechanism can effectively clean the air duct, the upper and lower air outlet baffles, and the left and right sweeping blades, which can effectively maintain a clean indoor environment and produce an obvious comfortable effect on human health. However, although the air guide plate assembly of the existing air conditioner indoor unit is provided with a detachable structure, the design is not user-friendly and the structure is complex. It is difficult for users to control and very laborious when disassembling. If you are not careful, it is easy to damage the air guide plate or the rotating shaft connecting the air guide plate.

[0005] For example, the patent publication number is "CN 117419449 A", in the invention title "A wind guide structure and air conditioner", it is disclosed that the air outlet frame includes a first air outlet plate and a second air outlet plate, and an air guide channel is provided between the first air outlet plate and the second air outlet plate; a volute tongue component is provided on the first air outlet plate, one end of the volute tongue component is connected to the first air outlet plate, and the other end of the volute tongue component extends in the direction of the first air outlet plate away from the second air outlet plate; a connecting portion for detachably connecting with the casing is provided on the second air outlet plate; the air guide plate is relatively rotatably connected to the air outlet frame; when the air conditioner needs to be cleaned, the air outlet frame is disassembled, and the first air outlet plate and the second air outlet plate are disassembled at the same time. After disassembly, the inner air duct of the air conditioner will have a larger space for cleaning operation, which is convenient for users to clean the inner air duct, and solves the technical problem of inconvenient cleaning of the air guide plate of the existing air conditioner; in this patent, the volute tongue part at the air outlet and the air guide plate deflected up and down and the inner air guide plate deflected left and right are all disassembled from the inner casing, and the overall structure is complicated, which is not only inconvenient to install and fix, but also the reliability of the transmission cannot be effectively guaranteed.

[0057] Continue as Figures 8 to 14 As shown, the left and right wind sweeping assembly 9 includes a plurality of left and right wind sweeping blades 90, a linkage swing rod 91 and a power receiving portion 92. The plurality of left and right wind sweeping blades 90 are evenly spaced and hingedly installed on the volute plate 81 along the length direction of the air-conditioning outlet. The end of the hinge axis of each left and right wind sweeping blade 90 is radially extended with a swing arm that is locked with the linkage swing rod 91 and rotates in coordination. The power receiving portion 92 is arranged at the hinge axis center of the left and right wind sweeping blades 90 at the outermost end of the volute plate 81, and is used to receive the external rotating shaft driving force to drive the circumferential deflection of the connected left and right wind sweeping blades 90 and synchronously drive all other left and right wind sweeping blades 90 to synchronously deflect left and right through the linkage swing rod 91. In this embodiment, the power receiving portion 92 is a hexagonal rotating shaft hole of a regular hexagonal driving shaft that is clamped to the center of the hinge axis of the left and right wind sweeping blades 90 along the direction of the air-conditioning outlet duct, and the volute plate 81 and the hexagonal rotating shaft hole are respectively provided with a avoidance opening 11 for the regular hexagonal driving shaft to be clamped in the direction of the air-conditioning outlet duct.

[0058] like Figures 11 to 14 As shown, an L-shaped main swing arm 12 is radially extended at the end of the inner hexagonal rotating shaft hole, which is rotatably matched with the bayonet hole at the end of the linkage swing rod 91 and swings left and right along the length direction of the air outlet of the air conditioner under the drive of the regular hexagonal driving shaft; an open hinge shaft 13 is arranged at the driving end of the L-shaped main swing arm 12, which is hinged and rotatably matched with the bayonet hole at the end of the linkage swing rod 91 and has a self-expanding opening structure in the center for self-expanding buckle locking of the entire rotating shaft. L-shaped self-expanding buckles 14 are symmetrically arranged on both sides of the hinge shaft of the left and right sweeping blades 90 corresponding to the inner hexagonal rotating shaft hole, which pass through the hinge holes on the volute tongue plate 81 and are self-expandingly clamped on the outer edge of the lower end surface of the hinge hole on both sides for locking the axial lower end surface of the hinge shaft of the left and right sweeping blades 90 in the hinge hole. The corresponding hinge hole on the upper end surface of the volute tongue plate 81 forms an active step surface 15 on the circumferential periphery for limiting and locking the axial upper end surface of the hinge shaft of the left and right sweeping blades 90. When the left and right sweeping blades 90 corresponding to the power receiving portion 92 are assembled in the hinge hole on the volute plate 81, the left and right sweeping blades 90 are axially clamped in the hinge hole after the L-shaped main swing arm 12 passes through the hinge hole obliquely.

[0059] Continue as Figures 11 to 14 As shown, the power receiving part 92 corresponds to the upper end surface of the volute tongue plate 81 of the circumferential periphery of the hinge shaft of the left and right sweeping blades 90. It is also provided with a plurality of sweeping angle positioning tooth grooves 16 evenly distributed along the circumferential outer edge of the hinge hole and meshed with the positioning blocks 900 protruding from the lower ends of the left and right sweeping blades 90 for limiting all the left and right sweeping blades 90 to be positioned at different sweeping angles after deflection. At the same time, the latch locking mechanism 10 at each end includes a toggle plate 100 and a latch head 101. The latch head 101 is installed at the outer end of the toggle plate 100 along the length direction of the volute tongue plate 81. The lower side of the toggle plate 100 extends with a clamping head 1000 that cooperates with the sliding groove on the bottom shell plate seat 80. The toggle plate 100 is clamped in the sliding groove of the bottom shell plate seat 80, and the latch head 101 is latched in the pin holes 23 of the shell on both sides of the air outlet duct of the air conditioner under the push of external force.

[0060] like Figures 11 to 18 As shown, the relative power receiving part 92 corresponds to the actively driven left and right wind sweeping blades 90. Under the drive of the linkage swing rod 91, the axial ends of the left and right wind sweeping blades 90 which are driven and hinged on the volute plate 81 are provided with an L-shaped driven swing arm 17 which is hinged and rotatably matched with the bayonet hole at the end of the linkage swing rod 91. The axial ends of the left and right wind sweeping blades 90 are also provided with a limit block 18 which is located on the opposite side of the L-shaped driven swing arm 17 and extends radially, and is used to be clamped on the outer edge of the lower end surface of the hinge hole after symmetrical cooperation on both sides, and is used to lock the axial lower end surface of the hinge axis of the left and right wind sweeping blades 90 in the hinge hole. The outer edge of the lower end surface of the corresponding hinge hole is also provided with a makeshift groove 180 which is convenient for the limit block 18 at the end to make way and abut against the lower end surface of the hinge hole; the corresponding hinge hole on the upper end surface of the volute plate 81 is formed with a driven step surface 19 which is used to limit and lock the axial upper end surface of the hinge axis of the left and right wind sweeping blades 90. The driven driving end of the L-shaped driven swing arm is also provided with an open hinge shaft 13 which is hinged and rotatably matched with the bayonet hole at the end of the linkage swing rod 91 and has a self-expanding opening structure in the center for self-expanding buckle locking of the entire rotating shaft.

[0061] When the driven left and right wind sweeping blades 90 are assembled in the hinge holes on the volute plate 81, the L-shaped driven swing arm tilts through the hinge holes, and at the same time, the limit block on the lower end face of the hinge shaft passes through the give way groove, and then, after being deflected at a certain angle along the circumferential direction, it is clamped on the outer edge of the lower end face of the hinge hole, so as to realize the axial locking of the upper and lower end faces of the hinge shaft of the driven left and right wind sweeping blades 90; after all the left and right wind sweeping blades 90 are assembled, the pin holes on the linkage swing rod 91 are matched with the open hinge shaft 13 at the end of the L-shaped main swing arm 12 and the open hinge shaft 13 of the L-shaped driven swing arm in turn, to complete the assembly of the left and right wind sweeping function.

[0062] In this embodiment, the air guide device a is mounted on the lower side of the outer frame shell 2 from the front to the back along the length direction from the lower side of the air outlet of the air conditioner, which solves the technical problem of inconvenient cleaning of the air guide plate, air duct and crossflow fan impeller of the existing air conditioner. It is not only convenient to disassemble, but also can clean the volute tongue more comprehensively and reliably, and is convenient to clean foreign matter in the air duct and on the crossflow fan impeller after disassembly. Moreover, the air guide device a cooperates with the regular hexagonal drive shaft of the driving motor on the air conditioner shell through the power receiving part 92 through the plug-in parallel to the axial direction, which is not only simple to disassemble and assemble, but also can effectively ensure the power transmission after mutual assembly. At the same time, since the motor and power line on the air guide device a that drive the left and right air sweeping components 9 to move are retained on the outer frame shell 2, in this way, the entire air guide device a is a non-charged material after disassembly, and can be soaked and cleaned after disassembly, effectively removing foreign matter and bacteria at the air guide outlet.
