Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and more specifically, to an air deflector assembly and an air conditioner. Background Technology

[0002] In the current structure of cabinet air conditioners, since the external air guide door is usually designed with an arc shape, there will inevitably be an angle difference when the left and right air guide doors are placed in the corresponding left and right positions of the air outlet frame, which will also cause the corresponding air guide door crank to have an angle difference.

[0003] Existing air conditioners use a parallelogram-shaped crank-connecting rod mechanism to avoid potential instability of the air guide damper caused by the aforementioned situation. However, this design requires that the left and right air guide dampers can only be installed on the corresponding left and right air guide damper cranks, making it inconvenient to distinguish and install the left and right air guide dampers. Of course, if the crank-connecting rod mechanism of the air conditioner is set to a non-parallelogram-shaped mechanism, a universal air guide damper and crank can be designed, which can save molds and facilitate installation. However, non-parallelograms have problems such as small opening and closing degree, dead points at the leftmost and rightmost extreme positions, and the crank angular velocity is not constant during the movement of the air guide damper, which causes the angular velocity of the crank to change continuously during the movement, thus leading to instability in the movement of the air guide damper. Summary of the Invention

[0004] This invention provides an air deflector assembly and an air conditioner, which can set the crank-connecting rod mechanism as a parallelogram mechanism and can also realize the commonality of left and right air deflectors and left and right air deflector cranks. Thus, while realizing the commonality of left and right air deflectors and air deflector cranks, the stable movement of the crank-connecting rod mechanism is ensured.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] In a first aspect, the present invention provides an air deflector assembly, comprising:

[0007] An air outlet frame, wherein the air outlet frame is provided with a first mounting hole and a second mounting hole;

[0008] Linkage, the linkage being used to connect with the drive component;

[0009] At least two air deflector cranks, each air deflector crank including a connecting part and a rotating shaft part, one end of the connecting part being connected to the connecting rod and the other end being connected to the rotating shaft part, the rotating shaft part being rotatably disposed in the first mounting hole or the second mounting hole, and the rotating shaft part being provided with a retaining part;

[0010] At least two air deflectors, each air deflector comprising at least a first latching portion and a second latching portion;

[0011] Wherein, when the rotating shaft is provided in the first mounting hole, the retaining part is engaged with the first engaging part; when the rotating shaft is provided in the second mounting hole, the retaining part is engaged with the second engaging part; and the connecting rod, the air guide crank provided in the first mounting hole, the air guide crank provided in the second mounting hole, and the line connecting the first mounting hole and the second mounting hole together form a parallelogram profile.

[0012] In the above embodiment, the connecting rod and the two air guide cranks provided in the first mounting hole and the second mounting hole are configured as a parallelogram crank-connecting rod mechanism, so that the angular velocity of the rotating shaft of the air guide crank is constant during rotation, thus making the air guide movement more stable and having sufficient opening and closing degree; when the rotating shaft is provided in the first mounting hole, the retaining part is engaged with the first engaging part; when the rotating shaft is provided in the second mounting hole, the retaining part is engaged with the second engaging part. This enables the air guide to be installed and fixed by engaging the retaining part and the first engaging part when it is set as the left air guide and is set on the left side of the air outlet frame, and by engaging the retaining part and the second engaging part when it is set as the right air guide and is set on the right side of the air outlet frame. This achieves the versatility of the left and right air guides and the left and right air guide cranks, which saves mold opening costs, simplifies object management, and makes it easy to distinguish and install the left and right air guides and the left and right air guide cranks during installation.

[0013] In an optional embodiment, the air guide door is provided with a pivot hole, the pivot part is disposed in the pivot hole, the first snap-fit ​​part and the second snap-fit ​​part are both disposed on the edge of the pivot hole, the line connecting the center of the first snap-fit ​​part and the pivot hole forms an angle with the line connecting the center of the second snap-fit ​​part and the pivot hole, and the angle between two adjacent snap-fit ​​parts is 10° to 15°.

[0014] In the above embodiment, the rotating shaft part passes through the rotating shaft hole, and the first and second locking parts are locking grooves provided at the edge of the rotating shaft hole, so that the locking part provided on the rotating shaft part can be locked with the first or second locking part while the rotating shaft part passes through the rotating shaft hole; the line connecting the center of the first locking part and the center of the rotating shaft hole is set at an angle with the line connecting the center of the second locking part and the rotating shaft hole, and the angle between two adjacent locking parts can be set to 10° to 15°, so that in the actual installation process, only the locking part needs to be rotated by the corresponding angle to complete the installation.

[0015] In an optional embodiment, the air guide door is further provided with a first marking part and a second marking part, the first marking part being adjacent to the first snap-fit ​​part and the second marking part being adjacent to the second snap-fit ​​part, the first marking part being used to correspond to the first mounting hole and the second marking part being used to correspond to the second mounting hole.

[0016] In the above embodiments, by providing a first marking portion near the first locking portion and a second marking portion near the second locking portion, and ensuring that the first marking portion corresponds to the first mounting hole and the second marking portion corresponds to the second mounting hole, assembly differentiation is facilitated. This allows the operator to easily engage the first locking portion of the air guide door with the locking portion of the air guide door crank when installing the air guide door in the first mounting hole, and to easily engage the second locking portion of the air guide door with the locking portion of the air guide door crank when installing the air guide door in the second mounting hole. Therefore, installation efficiency is effectively improved.

[0017] In an optional embodiment, each of the air guide cranks has multiple retaining portions, and each air guide is provided with multiple first retaining portions and multiple second retaining portions. The multiple retaining portions are arranged in a one-to-one correspondence with the multiple first retaining portions, or the multiple retaining portions are arranged in a one-to-one correspondence with the multiple second retaining portions.

[0018] In the above embodiments, the stability of the air guide door when it is installed on the air guide door crank is further improved by having multiple retaining parts and multiple first engaging parts in a one-to-one correspondence, or by having multiple retaining parts and multiple second engaging parts in a one-to-one correspondence.

[0019] In an optional embodiment, the retaining part is a rib protruding from the rotating shaft part, and the first retaining part and the second retaining part are both slots provided in the air guide door;

[0020] Alternatively, the holding parts are all slots provided on the rotating shaft, and the first and second locking parts are ribs protruding from the air guide door.

[0021] In the above embodiments, by setting the retaining part as a rib and the first engaging part as a slot, the rib can be embedded in the slot, so that the retaining part can engage with the first engaging part or the retaining part can engage with the second engaging part, thereby fixing the air guide door on the air guide door crank.

[0022] In an optional embodiment, the connecting rod includes a first segment and a second segment connected at an angle, the second segment being used to connect to a drive element;

[0023] The number of the air guide damper cranks is two, and the two rotating shafts are rotatably disposed in the first mounting hole and the second mounting hole, respectively. Both of the connecting parts are connected to the first segment, and the outlines of the plane containing the two connecting parts and the first segment are parallelograms.

[0024] In the above embodiment, by making the connecting part of the two air guide cranks and the first section of the connecting rod form a parallelogram mechanism, the connecting rod and the air guide crank move stably and have a large opening and closing angle, and the angular velocity of the rotating shaft is constant during rotation.

[0025] In an optional embodiment, the air deflector assembly further includes a drive component, which includes a motor and a motor crank disposed on the air outlet frame, the second segment being connected to the motor crank, and the outline of the motor crank, the second segment, and the plane containing one of the air deflector cranks being a parallelogram.

[0026] In the above embodiment, the motor drives the motor crank, which in turn drives the connecting rod to move. The connecting rod then drives the two air guide cranks to move synchronously, thereby enabling the two air guides to rotate through the two air guide cranks respectively.

[0027] In an optional embodiment, the drive component further includes a mounting base disposed on the air outlet frame, the motor disposed on the mounting base, and the mounting base having a limiting portion for limiting the movement trajectory of the motor crank.

[0028] In the above embodiments, by setting a limiting part on the mounting base, the smooth rotation of the motor crank is ensured, thereby further improving the stability of the connecting rod and the crank of the air guide, thus improving the stability of the air guide rotation.

[0029] In an optional embodiment, the air guide crank further includes a hook portion, which is disposed at the bottom of the rotating shaft portion and is used to hang the air guide.

[0030] In the above embodiment, by providing a hook portion at the bottom of the rotating shaft, the air guide door can be lifted by the hook portion, thereby making the air guide door stably installed on the air guide door crank and preventing the air guide door from falling off.

[0031] In a second aspect, the present invention provides an air conditioner, including a housing and an air guide damper assembly as described in any of the foregoing embodiments, the air guide damper assembly being disposed on the housing, the housing being provided with an air outlet, the air guide damper corresponding to the air outlet and used to open or close the air outlet.

[0032] The beneficial effects of the air deflector assembly and air conditioner provided in the embodiments of the present invention include: configuring the connecting rod and the two air deflector cranks disposed in the first and second mounting holes as a parallelogram-shaped crank-connecting rod mechanism, so that the angular velocity of the rotating shaft portion of the air deflector crank remains constant during rotation, thus making the air deflector movement more stable and having sufficient opening and closing degree; when the rotating shaft portion is disposed in the first mounting hole, the retaining portion engages with the first engaging portion; when the rotating shaft portion is disposed in the second mounting hole, the retaining portion engages with the second engaging portion. The connecting parts are snapped together, so that when the air guide door is set as the left air guide door on the left side of the air outlet frame, it can be installed and fixed by snapping together the holding part and the first snap-fit ​​part. When the air guide door is set as the right air guide door on the right side of the air outlet frame, it can be installed and fixed by snapping together the holding part and the second snap-fit ​​part. This achieves the versatility of the left and right air guide doors and the left and right air guide door cranks, which saves mold opening costs, simplifies material management, and makes it easy to distinguish and install the left and right air guide doors and the left and right air guide door cranks during the installation process.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0046] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0047] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0048] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0049] In the current structure of cabinet air conditioners, since the external air guide door is usually designed with an arc shape, there will inevitably be an angle difference when the left and right air guide doors are placed in the corresponding left and right positions of the air outlet frame, which will also cause the corresponding air guide door crank to have an angle difference.

[0050] Existing air conditioners use a parallelogram-shaped crank-connecting rod mechanism to avoid potential instability of the air guide damper caused by the aforementioned situation. However, this design requires that the left and right air guide dampers can only be installed on the corresponding left and right air guide damper cranks, making it inconvenient to distinguish and install the left and right air guide dampers. Of course, if the crank-connecting rod mechanism of the air conditioner is set to a non-parallelogram-shaped mechanism, a universal air guide damper and crank can be designed, which can save molds and facilitate installation. However, non-parallelograms have problems such as small opening and closing degree, dead points at the leftmost and rightmost extreme positions, and the crank angular velocity is not constant during the movement of the air guide damper, which causes the angular velocity of the crank to change continuously during the movement, thus leading to instability in the movement of the air guide damper.

[0051] Based on the above problems, this embodiment of the invention provides an air conditioner 10 that can set the crank connecting rod 200 mechanism as a parallelogram mechanism and can also make the left and right air guides 400 and the left and right air guide cranks 300 interchangeable. Thus, while ensuring the interchangeability of the left and right air guides 400 and the air guide cranks 300, the crank connecting rod 200 mechanism can be moved stably.

[0052] Please see Figure 1 The air conditioner 10 includes an indoor unit and an outdoor unit. The indoor unit includes a housing 12 and an air guide damper assembly 11. The air guide damper assembly 11 is disposed on the housing 12. The housing 12 is provided with an air outlet 13. The air guide damper 400 corresponds to the air outlet 13 and is used to open or close the air outlet 13.

[0053] Alternatively, the indoor unit can be a floor-standing unit.

[0054] For further information, please refer to [link / reference]. Figures 2 to 8 The air guide damper assembly 11 includes an air outlet frame 100, a connecting rod 200, an air guide damper crank 300, and an air guide damper 400. The number of air guide damper cranks 300 and air guide dampers 400 are the same and there can be multiple air guide dampers 400, which are respectively arranged on multiple air guide damper cranks 300.

[0055] The air outlet frame 100 is provided with a first mounting hole 110 and a second mounting hole 120. The first mounting hole 110 is located on the left side of the air outlet frame 100, and the second mounting hole 120 is located on the right side of the air outlet frame 100. Therefore, the first mounting hole 110 is used to install the left air guide damper 400, and the second mounting hole 120 is used to install the right air guide damper 400.

[0056] The connecting rod 200 is disposed on the air outlet frame 100 and is used to connect with the drive component 500; the air guide crank 300 includes a connecting part 310 and a rotating shaft part 320. One end of the connecting part 310 is connected to the connecting rod 200 and the other end is connected to the rotating shaft part 320. The rotating shaft part 320 is rotatably disposed in the first mounting hole 110 or the second mounting hole 120, and the rotating shaft part 320 is provided with a retaining part 330; the air guide 400 is provided with a first locking part 410 and a second locking part 420.

[0057] It is understandable that in actual operation, the drive component 500 drives the connecting rod 200 to move, thereby driving the air guide crank 300 connected to the connecting rod 200 to move, and the air guide crank 300 drives the air guide 400 to rotate, thereby realizing the opening or closing of the air outlet 13 by the air guide 400.

[0058] In this embodiment, the connecting rod 200, the air guide crank 300 disposed in the first mounting hole 110, the air guide crank 300 disposed in the second mounting hole 120, and the line connecting the first mounting hole 110 and the second mounting hole 120 together form a parallelogram profile (e.g., Figure 3 (As shown by the dashed line).

[0059] Therefore, the connecting rod 200 and the two damper cranks 300 provided in the first mounting hole 110 and the second mounting hole 120 are configured as a parallelogram crank-connecting rod 200 mechanism, so that the angular velocity of the rotating shaft portion 320 of the damper crank 300 is constant during rotation, thus making the movement of the damper 400 more stable and having sufficient opening and closing degree; when the rotating shaft portion 320 is provided in the first mounting hole 110, the retaining portion 330 is engaged with the first engaging portion 410; when the rotating shaft portion 320 is provided in the second mounting hole 120, the retaining portion 330 is engaged with the second engaging portion 420, thereby realizing the damper. When the air guide door 400 is set on the left side of the air outlet frame 100 as the left air guide door 400, it can be installed and fixed by engaging with the retaining part 330 and the first engaging part 410. When the air guide door 400 is set on the right side of the air outlet frame 100 as the right air guide door 400, it can be installed and fixed by engaging with the retaining part 330 and the second engaging part 420. This achieves the versatility of the left and right air guide doors 400 and the left and right air guide door cranks 300, which saves mold opening costs, simplifies object management, and makes it easy to distinguish and install the left and right air guide doors 400 and the left and right air guide door cranks 300 during the installation process.

[0060] It should also be noted that the air outlet frame 100 can also be provided with a third mounting hole, ... an nth mounting hole, etc., where n is the number of mounting holes provided in the air outlet frame 100, and n is greater than or equal to 3.

[0061] For example, when there are at least three mounting holes, there are also n air deflectors 400, and every two adjacent air deflector cranks 300 and connecting rods 200 form a parallelogram mechanism; in addition, the air deflector 400 is provided with a third engaging part... and an nth engaging part; therefore, when the air deflector 400 is placed in the third mounting hole, the air deflector 400 can be installed and fixed in the third mounting hole by engaging the holding part 330 with the third engaging part, the air deflector 400 can be installed and fixed in the fourth mounting hole by engaging the holding part 330 with the fourth engaging part, and similarly, the air deflector 400 can be installed and fixed in the nth mounting hole by engaging the holding part 330 with the nth engaging part.

[0062] Furthermore, the air deflector 400 is also provided with a first marking portion 430 and a second marking portion 440. The first marking portion 430 is adjacent to the first snap-fit ​​portion 410, and the second marking portion 440 is adjacent to the second snap-fit ​​portion 420. The first marking portion 430 is used to correspond to the first mounting hole 110, and the second marking portion 440 is used to correspond to the second mounting hole 120.

[0063] In this embodiment, a first marking portion 430 is provided near the first locking portion 410, and a second marking portion 440 is provided near the second locking portion 420. The first marking portion 430 corresponds to the first mounting hole 110, and the second marking portion 440 corresponds to the second mounting hole 120. This facilitates assembly differentiation. When the air deflector 400 is installed in the first mounting hole 110, it is convenient for the operator to engage the first locking portion 410 of the air deflector 400 with the locking portion 330 of the air deflector crank 300. Similarly, when the air deflector 400 is installed in the second mounting hole 120, it is convenient for the operator to engage the second locking portion 420 of the air deflector 400 with the locking portion of the air deflector crank 300. Therefore, installation efficiency is effectively improved.

[0064] Optionally, the first marking 430 can be the text "left", and the second marking 440 can be the text "right". When there are multiple mounting holes, a third marking...nth marking can also be provided. In this case, the markings can also be numbers, letters, or other marking types, without specific limitations.

[0065] Furthermore, each air deflector crank 300 has multiple retaining parts 330, and each air deflector 400 is provided with multiple first retaining parts 410 and multiple second retaining parts 420. The multiple retaining parts 330 are arranged in a one-to-one correspondence with the multiple first retaining parts 410, or the multiple retaining parts 330 are arranged in a one-to-one correspondence with the multiple second retaining parts 420.

[0066] In this embodiment, the stability of the air guide door 400 when installed on the air guide door crank 300 is further improved by having multiple retaining parts 330 be engaged with multiple first engaging parts 410 in a one-to-one correspondence, or by having multiple retaining parts 330 be engaged with multiple second engaging parts 420 in a one-to-one correspondence.

[0067] Optionally, there are two locking parts 330, and the line connecting the two locking parts 330 is located on the axis of the rotating shaft 320, that is, the two locking parts 330 are distributed at 180°. Since the first locking part 410 and the second locking part 420 are matched with the locking parts 330, the number of the first locking part 410 and the number of the second locking part 420 are also two. Furthermore, the straight line containing the two first locking parts 410 and the straight line containing the two second locking parts 420 are set at an angle. Therefore, during the installation process, it is only necessary to rotate the air guide crank 300 by a certain angle to engage the locking part 330 with the first locking part 410 or with the second locking part 420.

[0068] Furthermore, the holding part 330 is a rib protruding from the rotating shaft part 320, and the first locking part 410 and the second locking part 420 are both locking grooves provided in the air guide door 400.

[0069] In this embodiment, by setting the retaining part 330 as a rib and the first engaging part 410 as a slot, the rib can be embedded in the slot to achieve the engagement of the retaining part 330 with the first engaging part 410 or the engagement of the retaining part 330 with the second engaging part 420, thereby enabling the air guide door 400 to be installed and fixed on the air guide door crank 300.

[0070] Of course, in other embodiments of this application, the holding part 330 may also be a slot provided on the rotating shaft part 320, and the first engaging part 410 and the second engaging part 420 may both be ribs protruding from the air guide door 400. As long as the holding part 330 can be engaged with the first engaging part 410, or the holding part 330 can be engaged with the second engaging part 420, no specific limitation is made here.

[0071] Furthermore, the air guide damper 400 is provided with a pivot hole 450, the pivot part 320 is provided in the pivot hole 450, and the first snap-fit ​​part 410 and the second snap-fit ​​part 420 are both provided on the edge of the pivot hole 450.

[0072] In this embodiment, in the installed state, the rotating shaft portion 320 passes through the rotating shaft hole 450, and the first snap-fit ​​portion 410 and the second snap-fit ​​portion 420 are snap-fit ​​grooves provided at the edge of the rotating shaft hole 450, so that while the rotating shaft portion 320 passes through the rotating shaft hole 450, the retaining portion 330 provided on the rotating shaft portion 320 can be snapped with the first snap-fit ​​portion 410 or the second snap-fit ​​portion 420.

[0073] The center line connecting the first snap-fit ​​part 410 and the center line connecting the second snap-fit ​​part 420 and the center line connecting the second snap-fit ​​part 420 and the center line connecting the second snap-fit ​​part 420 is set at an angle of 10° to 15°, as shown in the figure. The angle between the first snap-fit ​​part 410 and the second snap-fit ​​part 420 is 10° to 15°. When there are multiple snap-fit ​​parts, the sum of the angles of the multiple snap-fit ​​parts is up to 170°.

[0074] It is understandable that when there are multiple air guides 400, multiple locking parts will also be provided accordingly. Usually, the angle between the line connecting two adjacent locking parts and the center of the pivot hole 450 is 10° to 15°. When the sum of the angles of multiple locking parts is 170°, the angle between two adjacent locking parts is 10°. In this case, there are 17 air guides and 17 locking parts (i.e., including the first locking part, the second locking part, ... the seventeenth locking part).

[0075] Furthermore, the link 200 includes a first segment 210 and a second segment 220 connected at an angle, the second segment 220 being used to connect with the drive member 500;

[0076] There are two air deflector cranks 300. The two rotating shafts 320 are rotatably disposed in the first mounting hole 110 and the second mounting hole 120, respectively. The two connecting parts 310 are connected to the first section 210, and the contours of the plane containing the two connecting parts 310 and the connecting rod 200 are parallelograms.

[0077] In this embodiment, by making the connecting part 310 of the two air guide cranks 300 and the first section 210 of the connecting rod 200 form a parallelogram mechanism, the connecting rod 200 and the air guide cranks 300 move stably and have a large opening and closing angle, and the rotating shaft part 320 has a constant angular velocity during rotation.

[0078] Furthermore, the air deflector assembly 11 also includes a drive component 500, which includes a motor 510 and a motor crank 520 disposed on the air outlet frame 100. The second segment 220 is connected to the motor crank 520. The outline of the motor crank 520, the connecting rod 200, and the plane containing one of the air deflector cranks 300 is a parallelogram.

[0079] In this embodiment, the motor 510 drives the motor crank 520, which in turn drives the connecting rod 200 to move. The connecting rod 200 then drives the two air guide cranks 300 to move synchronously, thereby enabling the two air guides 400 to rotate through the two air guide cranks 300 respectively.

[0080] It is worth mentioning that the motor crank 520, the second section 220 of the connecting rod 200, and the adjacent air guide crank 300 also form a parallelogram mechanism to further improve the stability of the movement of the motor crank 520, the connecting rod 200, and the air guide crank 300.

[0081] Furthermore, the drive unit 500 also includes a mounting base 530, which is disposed on the air outlet frame 100. The motor 510 is disposed on the mounting base 530. The mounting base 530 is provided with a limiting part, which is used to limit the movement trajectory of the motor crank 520.

[0082] In this embodiment, by setting a limiting part on the mounting base 530, the rotation of the motor crank 520 is ensured to be smooth, thereby further improving the stability of the movement of the connecting rod 200 and the air guide crank 300, and thus improving the stability of the rotation of the air guide 400.

[0083] Furthermore, the air guide crank 300 also includes a hook portion 340, which is connected to the bottom of the rotating shaft portion 320 and is used to hang the air guide 400.

[0084] In this embodiment, a hook portion 340 is provided at the bottom of the rotating shaft portion 320 so that the air guide door 400 can be lifted by the hook portion 340, thereby making the air guide door 400 stably installed on the air guide door crank 300 and preventing the air guide door 400 from falling off.

[0085] In summary, the embodiments of the present invention provide an air deflector assembly 11 and an air conditioner 10. The connecting rod 200 and two air deflector cranks 300 disposed in the first mounting hole 110 and the second mounting hole 120 are configured as a parallelogram-shaped crank-connecting rod 200 mechanism. This ensures that the angular velocity of the rotating shaft portion 320 of the air deflector crank 300 remains constant during rotation, thus making the movement of the air deflector 400 more stable and providing sufficient opening and closing degree. When the rotating shaft portion 320 is disposed in the first mounting hole 110, the retaining portion 330 engages with the first engaging portion 410; when the rotating shaft portion 320 is disposed in the second mounting hole 120, the retaining portion 330 engages with the second engaging portion 410. The first snap-fit ​​part 410 engages with the second snap-fit ​​part 420 to secure the air guide door 400 when it is positioned as the left air guide door 400 on the left side of the air outlet frame 100. When the air guide door 400 is positioned as the right air guide door 400 on the right side of the air outlet frame 100, it can be secured by engaging the second snap-fit ​​part 420 with the second snap-fit ​​part 330. This achieves the versatility of the left and right air guide doors 400 and the left and right air guide door cranks 300, saving mold opening costs, simplifying object management, and making it easy to distinguish and install the left and right air guide doors 400 and the left and right air guide door cranks 300 during installation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
