Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] In some air conditioners on the market, the crossflow blades are rotatably installed in the air duct, a first notch is opened on the end wall of one end of the air duct, and a matching rotating shaft protruding from one end of the crossflow blade passes through the first notch and is plugged into the output shaft of the motor.

[0003] In this type of air conditioner, when removing the crossflow fan blade from the air duct, it is necessary to first pull the crossflow fan blade away from the motor to disengage the mating shaft of the crossflow fan blade from the motor output shaft, and then remove the crossflow fan blade from the air duct in the direction of the opening of the first notch.

[0004] Since the open structure of the first notch cannot provide comprehensive circumferential limiting support for the mating shaft of the crossflow fan blade, it is difficult for the mating shaft to maintain stable axial movement during the process of plugging in or separating from the motor output shaft, which makes it extremely difficult to plug in and separate the mating shaft from the output shaft of the motor, making it difficult to disassemble and assemble the crossflow fan blade. Utility Model Content

[0005] The utility model solves the problem that the air duct of the existing air conditioner cannot provide comprehensive circumferential limiting support for the matching rotating shaft of the crossflow fan blade, which makes it difficult to disassemble and assemble the crossflow fan blade.

[0006] In order to solve the above problems, the utility model provides an air conditioner, which can provide comprehensive circumferential limiting support for the matching rotating shaft of the crossflow fan blade, so as to ensure that the crossflow fan blade can be smoothly and quickly disassembled and assembled.

[0007] The embodiment of the utility model provides a technical solution:

[0008] An air conditioner, comprising an air conditioner body, a motor and a crossflow fan blade, wherein the motor is mounted on the air conditioner body, an air duct is provided on the air conditioner body, the crossflow fan blade is mounted in the air duct, the air duct has an installation end wall, and the crossflow fan blade and the motor are respectively located on opposite sides of the installation end wall;

[0009] A limiting piece is arranged on the installation end wall, and a limiting channel is arranged through the limiting piece. A mating shaft is protruded from one end of the crossflow fan blade close to the installation end wall, and the mating shaft passes through the limiting channel and is plugged into the motor; the crossflow fan blade is used to drive the mating shaft to slide axially along the limiting channel under the action of external force until it is disconnected from the motor.

[0010] The air conditioner provided by the embodiment of the utility model is additionally provided with a limiting member on the installation end wall of the air duct. The limiting member provides comprehensive circumferential limiting support for the matching rotating shaft of the crossflow fan blade, thereby ensuring that the crossflow fan blade is always in the limiting channel of the limiting member during the disassembly and assembly process, and maintains stable axial movement under the circumferential limitation of the limiting channel, thereby smoothly completing the plug-in or disconnection with the motor.

[0011] In an optional embodiment, a first notch is formed on the edge of the mounting end wall, and the mating shaft passes through the first notch and the limiting channel to be plugged into the motor.

[0012] The matching rotating shaft passes through the first notch and the limiting channel. When the matching rotating shaft is separated from the motor, the hole wall of the limiting channel provides comprehensive limiting support to the matching rotating shaft in the circumferential direction.

[0013] In an optional embodiment, the limiting member is located between the mounting end wall and the motor and is detachably connected to the mounting end wall. The limiting channel is circumferentially closed, and the end of the mating shaft away from the cross-flow fan blade passes through the first notch and the limiting channel in sequence and is connected to the motor.

[0014] The limiting member is located between the mounting end wall and the motor to avoid occupying the internal space of the air duct and not affecting the arrangement of the crossflow blades in the air duct. Furthermore, the limiting member is detachably connected to the mounting end wall to achieve synchronous disassembly and assembly with the crossflow blades in the air duct. After the mating shaft is separated from the motor, the limiting member is removed, and the mating shaft can still smoothly withdraw from the first notch, that is, the limiting member does not affect the mating shaft from being embedded in or withdrawing from the first notch. Therefore, the air conditioner provided by the embodiment of the utility model can provide comprehensive circumferential limiting support for the mating shaft of the crossflow blades, ensuring that the crossflow blades can be disassembled and assembled smoothly and quickly.

[0015] In an optional embodiment, the first notch is in an arc shape, the limiting channel is in a circle, the limiting channel is coaxially arranged with the first notch, and the radius of the limiting channel is less than or equal to the radius of the first notch.

[0016] The radius of the limiting channel is smaller than the radius of the first notch, ensuring that the limiting member provides reliable limiting support for the matching rotating shaft.

[0017] In an optional embodiment, a side surface of the limit member is provided with a fitting surface and a supporting surface which are angled with each other, the fitting surface is fitted and connected to a side surface of the mounting end wall, and the supporting surface is supported by an edge of the first notch provided on the mounting end wall.

[0018] The fitting of the limiting member and the mounting end wall, and the abutting of the abutting surface and the edge of the mounting end wall, enable the matching of the limiting member and the mounting end wall in multiple directions, making the assembly structure of the limiting member and the mounting end wall more stable and reliable.

[0019] In an optional embodiment, the number of the abutting surfaces is two, and the two abutting surfaces are respectively located on opposite sides of the limiting channel, and the two abutting surfaces both abut against the edge of the first notch formed on the installation end wall.

[0020] The two abutting surfaces abut against the edge of the mounting end wall at opposite sides of the limiting channel, further improving the stability of the limiting member. The gravity of the rotating shaft can be evenly transmitted to the edge of the mounting end wall through the two abutting surfaces, ensuring the overall structure is stable and reliable.

[0021] In an optional embodiment, a retaining boss is convexly provided on the fitting surface, one side edge of the retaining boss extends along the circumference of the limiting channel, and the two abutting surfaces are respectively located on the end walls of the retaining boss at both ends of the circumference of the limiting channel.

[0022] In an optional embodiment, a threaded hole is formed on the mounting end wall on one side corresponding to the fitting surface, and a mounting hole is formed on the fitting surface that passes through the limiting member, and the mounting hole is aligned with the threaded hole; the air conditioner also includes a threaded connector that passes through the mounting hole and is threadedly engaged with the threaded hole.

[0023] When the fitting surface is fitted with one side surface of the mounting end wall and the abutting surface is abutting with the edge of the mounting end wall, the threaded connector is passed through the mounting hole and screwed into the threaded hole to complete the connection between the position-limiting member and the mounting end wall. After the mating shaft is disconnected from the motor, the threaded connector is screwed out to release the connection between the position-limiting member and the mounting end wall, and the mating shaft can smoothly withdraw from the first notch to complete the removal of the crossflow fan blade.

[0024] In an optional embodiment, a positioning hole is further provided on a side of the mounting end wall corresponding to the fitting surface, and a positioning column is protrudingly provided on the fitting surface, and the positioning column is plugged into the positioning hole.

[0025] By plugging the positioning column protruding from the fitting surface into the positioning hole opened on the installation end wall, the installation hole and the threaded hole are automatically aligned, which facilitates the rapid assembly of the subsequent threaded connector.

[0026] In an optional embodiment, there are plural positioning holes and plural positioning posts, and the plural positioning posts are respectively plugged into the plural positioning holes, and the plural positioning posts are spaced apart in the circumferential direction of the limiting channel.

[0027] A plurality of positioning posts spaced apart in the circumferential direction of the limiting channel are respectively plugged into a plurality of positioning holes, which can ensure a reliable positioning effect and improve positioning accuracy.

[0028] In an optional embodiment, the number of the threaded holes, the mounting holes and the threaded connectors are all multiple, and the multiple mounting holes and the multiple positioning columns are alternately arranged in sequence in the circumferential direction of the limiting channel.

[0029] The plurality of mounting holes and the plurality of positioning columns are alternately arranged in sequence in the axial direction of the limiting channel, so that the strength of the limiting component can be improved.

[0030] In an optional embodiment, the limiting member is rotatably disposed in the first notch, and a rotation centerline of the limiting member is perpendicular to the installation end wall;

[0031] A second notch connected to the limiting channel is formed on an outer edge of one side of the limiting member in the circumferential direction. The limiting member is used to rotate under the action of an external force so that the notch wall of the first notch covers or releases the second notch.

[0032] When the mating shaft passes through the limiting channel and is plugged into the motor, the gap wall of the first gap covers the second gap, thereby limiting the mating shaft in the limiting channel, and providing comprehensive support for the mating shaft in the circumferential direction. When the crossflow fan blade needs to be removed, the limiting member is rotated until the second gap is exposed, and the mating shaft of the crossflow fan blade can be withdrawn from the second gap, thereby realizing the rapid removal of the crossflow fan blade.

[0033] In an optional embodiment, a matching groove is provided on the peripheral ring of the limiting member, and a matching rib is protruded on the notch wall of the first notch. The matching rib is embedded in the matching groove and slidably matched with the matching groove.

[0034] By providing a matching groove on the periphery of the limiting member, which is slidably matched with the matching rib convexly provided on the notch wall of the first notch, the guiding and limiting of the rotation process of the limiting member can be achieved, ensuring that the rotation process of the limiting member is smooth and stable.

DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] See also Figure 1 and Figure 2 , Figure 1 FIG. 1 is a partial structural diagram of an air conditioner 100 provided in the first embodiment of the utility model. Figure 2 Shown Figure 1 A magnified schematic diagram of area A in the middle.

[0048] The air conditioner 100 provided in this embodiment includes an air conditioner body 110, a motor (not shown in the figure) and a crossflow fan blade 120. The motor is installed on the air conditioner body 110. The air conditioner body 110 is provided with an air duct 111. The crossflow fan blade 120 is installed in the air duct 111. The air duct 111 has an installation end wall 112. The crossflow fan blade 120 and the motor are respectively located on opposite sides of the installation end wall 112. In addition, a limit member 130 is detachably provided on the installation end wall 112. A limit channel 131 is provided through the limit member 130. A matching shaft 121 is convexly provided at one end of the crossflow fan blade 120 close to the motor. The matching shaft 121 passes through the limit channel 131 and is plugged into the motor.

[0049] It is understandable that the end of the rotating shaft 121 away from the crossflow blade 120 passes through the limiting channel 131 and is plugged into the output shaft of the motor. In actual application, the output shaft of the motor rotates to drive the crossflow blade 120 to rotate in the air duct 111.

[0050] When the crossflow blade 120 needs to be removed, a force can be applied to the crossflow blade 120 in a direction away from the motor to drive the crossflow blade 120 to move in a direction away from the motor, that is, to drive the mating shaft 121 to move along the limiting channel 131 until it is disconnected from the motor. After the mating shaft 121 is disconnected from the motor, the connection between the limiting member 130 and the mounting end wall 112 is released, and the crossflow blade 120 can be removed from the air duct 111.

[0051] When the crossflow fan blade 120 needs to be reinstalled in the air duct 111 after cleaning, the limiting member 130 can be first sleeved on the matching rotating shaft 121 of the crossflow fan blade 120, and then the limiting member 130 is connected to the installation end wall 112. After completion, a force is applied to the crossflow fan blade 120 in the direction of approaching the motor, driving the crossflow fan blade 120 to move in the direction of approaching the motor, that is, driving the matching rotating shaft 121 to move along the limiting channel 131 until it is plugged into the motor.

[0052] During the process of plugging or unplugging the crossflow fan blade 120 and the motor, the matching shaft 121 of the crossflow fan blade 120 is always in the limiting channel 131 of the limiting member 130, and the hole wall of the limiting channel 131 always provides a comprehensive limiting support for the matching shaft 121 in the circumferential direction, ensuring that the axial movement of the matching shaft 121 and the crossflow fan blade 120 in the air duct 111 is smooth and stable, thereby completing the plugging and unplugging with the motor conveniently and quickly. It can be seen that the air conditioner 100 provided in this embodiment has a convenient and quick disassembly process of the crossflow fan blade 120, which saves time and effort.

[0053] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is an exploded schematic diagram of a partial structure of the air conditioner 100 provided in this embodiment. Figure 4 Shown Figure 3 A magnified schematic diagram of area B.

[0054] In this embodiment, a first notch 1121 is formed on the edge 1122 of the mounting end wall 112 , and the rotating shaft 121 passes through the first notch 1121 and the limiting channel 131 to be plugged into the motor.

[0055] It is understandable that the first notch 1121 on the edge 1122 of the mounting end wall 112 also provides a certain degree of limiting support for the mating shaft 121 . Due to its open structure, some circumferential positions of the mating shaft 121 cannot be limited and supported by the first notch 1121 .

[0056] In actual application, during the process of disassembling the crossflow fan blade 120, after the mating shaft 121 is disconnected from the motor, the mating shaft 121 still remains in a state of passing through the first notch 1121 and the limiting channel 131. In this case, after the connection between the limiting member 130 and the mounting end wall 112 is released, the mating shaft 121 can smoothly withdraw from the first notch 1121, driving the limiting member 130 to leave the air duct 111 synchronously.

[0057] Similarly, during the installation of the crossflow fan blade 120, after the stopper 130 is sleeved on the mating shaft 121, the crossflow fan blade 120 is placed into the air duct 111, so that the mating shaft 121 is smoothly inserted into the first notch 1121, and then the stopper 130 is connected to the installation end wall 112. After completion, the crossflow fan blade 120 is pushed rightward to drive the mating shaft 121 to move along the stopper channel 131 until it is plugged into the motor.

[0058] Please refer to Figure 5 , Figure 5 Shown Figure 3 A schematic structural diagram of the middle limiting member 130.

[0059] In order to facilitate the connection between the limiting member 130 and the mounting end wall 112, in this embodiment, a side surface of the limiting member 130 is provided with a fitting surface 132 and a supporting surface 133 which are angled with each other. The fitting surface 132 is fitted and connected to a side surface of the mounting end wall 112, and the supporting surface 133 is supported by an edge 1122 of a first notch 1121 provided on the mounting end wall 112.

[0060] It can be understood that, through the abutment between the abutting surface 133 and the edge 1122 of the mounting end wall 112, the abutting direction is the same as the direction of gravity, that is, the gravity effect of the cross-flow fan blade 120 on the limiting member 130 can be transmitted to the edge 1122 of the mounting end wall 112, that is, to the air duct 111, thereby ensuring the stability of the overall structure.

[0061] In order to avoid occupying the internal space of the air duct 111, in this embodiment, the limit member 130 is located between the mounting end wall 112 and the motor, that is, the fitting surface 132 of the limit member 130 fits with the side of the mounting end wall 112 close to the motor, and the end of the rotating shaft 121 away from the cross-flow fan blade 120 passes through the first notch 1121 and the limiting channel 131 in sequence and is connected to the motor.

[0062] In this embodiment, the first notch 1121 is arc-shaped, the limiting channel 131 is circular, and the limiting channel 131 is coaxially arranged with the first notch 1121. In order to ensure that the limiting member 130 can provide reliable support for the mating rotating shaft 121, the radius of the limiting channel 131 is less than or equal to the radius of the first notch 1121.

[0063] In order to further improve the stability of the assembly structure, there are two abutting surfaces 133 , which are respectively located on opposite sides of the limiting channel 131 , and both abut against the edge 1122 of the first notch 1121 formed on the installation end wall 112 .

[0064] In fact, in this embodiment, a semi-circular boss structure is convexly provided on the side of the limiting member 130 facing away from the motor, the inner edge of the boss structure extends a certain distance along the periphery of the limiting channel 131, and the end faces of the boss structure at both ends in the extension direction are two abutting surfaces 133. In this embodiment, the abutting surface 133 is perpendicular to the fitting surface 132, and the edge 1122 of the mounting end wall 112 is perpendicular to the side wall of the mounting end wall 112. When the abutting surface 133 abuts against the edge 1122 of the mounting end wall 112, the fitting surface 132 naturally fits against the side wall of the mounting end wall 112.

[0065] When the two abutting surfaces 133 and the edge 1122 of the mounting end wall 112 are partially abutted at both ends of the first notch 1121, the inner edge of the boss structure is buckled on the first notch 1121, which is equivalent to covering the first notch 1121, and together forming a closed channel, thereby providing comprehensive circumferential limiting support for the mating shaft 121.

[0066] Regarding the detachable connection between the limit member 130 and the mounting end wall 112, in the present embodiment, a threaded hole 1123 is provided on one side of the mounting end wall 112 corresponding to the fitting surface 132, and a mounting hole 1321 penetrating the limit member 130 is provided on the fitting surface 132, and the mounting hole 1321 is aligned with the threaded hole 1123; the air conditioner 100 also includes a threaded connector, which passes through the mounting hole 1321 and is threadably matched with the threaded hole 1123.

[0067] It is understandable that the threaded connector can be a screw. During the assembly process, after the abutting surface 133 of the stopper 130 is abutted against the edge 1122 of the mounting end wall 112, the abutting surface 132 of the stopper 130 abuts against the side surface of the mounting end wall 112 close to the motor. At this time, align the mounting hole 1321 on the stopper 130 with the threaded hole 1123 on the mounting end wall 112. After alignment, pass the threaded connector through the mounting hole 1321 and screw it into the threaded hole 1123 to complete the detachable connection between the stopper 130 and the mounting end wall 112. When it is necessary to disassemble the stopper 130, just screw the threaded connector out of the threaded hole 1123 and then withdraw it from the mounting hole 1321.

[0068] In order to facilitate the positioning of the mounting hole 1321 and the threaded hole 1123 and further simplify the assembly process, in this embodiment, a positioning hole 1124 is further opened on one side of the mounting end wall 112 corresponding to the fitting surface 132, and a positioning column 1322 is protruded from the fitting surface 132, and the positioning column 1322 is plugged into the positioning hole 1124.

[0069] It is understandable that, in the actual assembly process, after the positioning column 1322 protruding from the fitting surface 132 is correspondingly inserted into the positioning hole 1124 on the mounting end wall 112, the limiting channel 131 of the limiting member 130 is aligned with the first notch 1121, the abutting surface 133 abuts against the edge 1122 of the mounting end wall 112, and the fitting surface 132 abuts against the side of the mounting end wall 112 close to the motor. In this state, the threaded connector can be directly passed through the mounting hole 1321 and screwed into the threaded hole 1123.

[0070] To improve the accuracy of automatic positioning, in this embodiment, the number of positioning holes 1124 and positioning posts 1322 are both multiple, and the multiple positioning posts 1322 are respectively plugged into the multiple positioning holes 1124 , and the multiple positioning posts 1322 are spaced apart in the circumferential direction of the limiting channel 131 .

[0071] In addition, in order to improve the stability of the assembly structure, in this embodiment, the number of threaded holes 1123, mounting holes 1321 and threaded connectors are all multiple, and the multiple mounting holes 1321 and the multiple positioning columns 1322 are alternately arranged in sequence in the circumferential direction of the limiting channel 131.

[0072] It can be understood that since the multiple mounting holes 1321 and the multiple positioning columns 1322 are alternately arranged in sequence in the circumferential direction of the limiting channel 131, after the multiple threaded connectors are respectively passed through the corresponding mounting holes 1321 and screwed into the corresponding threaded holes 1123, the multiple threaded connectors and the multiple positioning columns 1322 are alternately arranged, and the multiple positioning columns 1322 play a role of structural reinforcement, ensuring that the connection structure between the limiting member 130 and the mounting end wall 112 is stable and reliable.

[0073] Please refer to Figure 6 and Figure 7 , Figure 6 FIG. 1 is a schematic diagram of a partial structure of an air conditioner 100 provided by another embodiment of the present invention in a state. Figure 7 Shown Figure 6 Enlarged schematic diagram of the middle C area;

[0074] The difference between the air conditioner 100 provided in this embodiment and the first embodiment lies in the structure of the stopper 130 itself and the connection structure between the stopper 130 and the mounting end wall 112. Specifically, in this embodiment, the stopper 130 is rotatably arranged in the first notch 1121, and the rotation centerline of the stopper 130 is perpendicular to the mounting end wall 112. In addition, a second notch 134 connected to the stopper channel 131 is provided on the outer edge of one side of the circumference of the stopper 130, and the stopper 130 is used to rotate under the action of an external force so that the notch wall of the first notch 1121 covers or releases the second notch 134.

[0075] Understandably, Figure 7 What is shown is the state where the notch wall of the first notch 1121 covers the second notch 134. In this state, the channel wall of the limiting channel 131 and the notch wall of the first notch 1121 realize the segmented limiting of the circumferential direction of the matching rotating shaft 121 of the cross-flow fan blade 120, and together form a channel for the circumferential upper limit of the matching rotating shaft 121, providing comprehensive circumferential support and limiting for the matching rotating shaft 121.

[0076] Please refer to Figure 8 and Fig. 9 , Figure 8 FIG. 1 is a schematic diagram showing a partial structure of an air conditioner 100 provided by another embodiment of the present invention in another state. Fig. 9 Shown Figure 8 A magnified schematic diagram of region D in the middle.

[0077] When the cross-flow blade 120 needs to be disassembled, the limiting member 130 only needs to be rotated until the first notch 1121 releases the cover of the second notch 134 , so that the second notch 134 is opened. Fig. 9 The state shown is that the second notch 134 is open. In this state, the rotating shaft 121 can be withdrawn from the limiting passage 131 through the second notch 134, so that the crossflow blade 120 can be disassembled.

[0078] Similarly, when the crossflow blade 120 needs to be installed, the mating shaft 121 of the crossflow blade 120 only needs to be inserted into the limiting channel 131 through the second notch 134 , and then the limiting member 130 is rotated until the first notch 1121 completes the covering of the second notch 134 .

[0079] Regarding the specific connection method between the limit member 130 and the mounting end wall 112, in this embodiment, a mating groove 135 is provided on the peripheral ring of the limit member 130, and a mating rib (not shown in the figure) is protruded on the notch wall of the first notch 1121. The mating rib is embedded in the mating groove 135 and slidably cooperates with the mating groove 135.

[0080] By providing a matching groove 135 on the periphery of the limiting member 130 and slidingly cooperating with the matching rib protruding on the notch wall of the first notch 1121, the limiting member 130 is guided and limited during its rotation, ensuring that the limiting member 130 rotates smoothly.

[0081] In summary, the air conditioner 100 provided in this embodiment provides a full circumferential limiting support for the mating rotating shaft 121 by setting a limiting member 130 on the installation end wall 112, thereby ensuring that the crossflow fan blades 120 can be smoothly and quickly assembled and disassembled.

[0082] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
