Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a swing assembly and air control device. Background Technology

[0002] To improve product aesthetics and save installation and storage space, it is necessary to reduce the overall size of the bathroom heater, especially in the vertical direction of the installation surface. This would significantly increase the ceiling height in the bathroom, thereby improving headroom for users. Currently, the faceplate, fan, and casing of existing bathroom heaters are arranged vertically along the installation surface. This arrangement is standard and universal, making it difficult to further reduce the size of the bathroom heater in the vertical direction, thus hindering further increases in bathroom ceiling height. Utility Model Content

[0003] In view of this, the present invention provides a swing assembly and an air control device, which aims to further reduce the height of the air control device based on the existing technology to reduce the space occupied by the air control device, thereby facilitating user use and manufacturer warehousing.

[0004] The swing assembly of this utility model includes an air outlet frame, a swing blade, an input component, a drive component, and an output component. The air outlet frame is provided with a vent for connecting to the air duct of the main unit. The swing blade is rotatably disposed on the vent around a preset swing center and is equipped with the input component. The output component is connected to the output end of the drive component and is engaged with the input component. The swing blade includes an inlet frame edge that can rotate to point towards the main unit. The distance from the inlet frame edge to the preset swing center is less than the distance from the inlet frame edge to the output end.

[0005] In some implementations, the preset swing center and output end are both no higher than the windshield opening.

[0006] In some embodiments, the inlet frame edge is located on the first half side, and the engagement position of the input component and the output component is located on the second half side. The first half side and the second half side are located on both sides of the dividing surface, which is a plane passing through a preset swing center and parallel to the height direction of the air outlet frame.

[0007] In some embodiments, the plane containing the preset swing center and the rotation center of the output component is inclined at an angle relative to the cutting plane, and the angle between the two is in the range of 30° to 60°.

[0008] In some embodiments, the input element includes an input gear fixed to the oscillating leaf, and the output element includes an output gear mounted on the output end, with the input gear and output gear meshing together.

[0009] In some embodiments, the swing blade includes an air guide plate that can rotate around a preset swing center to cover the air outlet frame. The input gear is a bow-shaped gear or a sector gear with a positioning surface, the positioning surface being flush with or lower than the outer side of the air guide plate.

[0010] In some implementations, the input gear is attached to one side of the air outlet frame of the air guide plate via a positioning surface.

[0011] In some embodiments, the oscillating blade includes a guide vane, and the guide vane is capable of rotating with the oscillating blade around a preset swing center until it covers the air outlet frame, wherein:

[0012] The air guide plate includes a first side and a second side arranged opposite to each other. When the air guide plate covers the air outlet frame, the distance from the first side to the preset swing center is less than the distance from the second side to the preset swing center, and the first side forms the frame entry side; and / or,

[0013] When the air guide plate covers the air outlet frame, the air guide plate protrudes from the side wall of the air window and forms a baffle that is spaced apart from the main unit. The input component is installed on the side of the baffle that is close to the main unit, and both the drive component and the output component are covered by the baffle.

[0014] In some embodiments, the air outlet frame includes a baffle wall, and the two sides of the baffle wall are respectively configured with an air outlet window and a storage cavity.

[0015] The partition wall has a through hole connecting a ventilation window and a storage cavity, the through hole allowing the output component to engage with the input component; and / or

[0016] Both the output component and the drive component are located within the housing cavity; and / or,

[0017] The partition wall includes a fitted wall, which abuts against the air guide plate when the air outlet frame is covered by the air guide plate.

[0018] The air control device of this utility model includes a main unit and the above-mentioned swing assembly. The air outlet frame is installed on the main unit, and the main unit has an internal air duct connected to a ventilation window.

[0019] Compared with the prior art, the swing assembly of this utility model has the following beneficial effects: the inlet edge of the swing blade no longer swings around the output end of the drive component, but swings around a preset swing center that is closer to the inlet edge. When the swing blade rotates around the preset swing center until the inlet edge points to the main unit, the inlet edge is closer to the air window opening, that is, the size of the swing blade extending into the air window is smaller. Therefore, the depth of the air window can be reduced so that the air outlet frame is lower. The lower air outlet frame means that the height of the air conditioning device is smaller, the installation gap between the mask and the main unit is narrowed, and the space occupied by the air conditioning device is less. This solves the problem of existing similar products occupying a large installation space and a lot of storage space. Therefore, the air conditioning device of this utility model is more user-friendly for installation and use, as well as for the storage of manufacturers and distributors. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] This invention first provides a swing assembly for an air conditioning device, and then provides an air conditioning device including the swing assembly. The specific form of the air conditioning device is not limited, and it can be a bathroom heater, a fresh air system, a ventilation fan, an air conditioner, etc.

[0030] See Figures 1-2 , Figures 4-5 , Figure 1 The swing assembly shown is applied to a bathroom heater. The bathroom heater can be installed on a horizontally installed bathroom ceiling, a horizontally installed indoor ceiling, or a vertical wall. This utility model does not limit the specific installation location of the air control equipment. Bathroom ceiling, indoor ceiling, and vertical wall are collectively referred to as the installation surface of the air control equipment.

[0031] The following uses a bathroom heater and its swing assembly as examples to introduce the structure and working principle of the air control device and swing assembly of this utility model.

[0032] In addition to the swing assembly, the air control equipment also includes a main unit 80. The main unit 80 has an air duct for scheduling and transporting airflow. The swing assembly includes an air outlet frame 10, a swing blade 20, and a drive unit 50. The air outlet frame 10 is installed in the main unit 80. The air outlet frame 10 has a window 11 connecting the ventilation duct and the indoor space. The swing blade 20 is rotatably disposed in the window 11 around a preset swing center. The drive unit 50 drives and connects to the swing blade 20 and provides the power required for the swing blade 20 to rotate around the preset swing center. The swing blade 20 includes a guide plate 21 for guiding the airflow out of the window 11. The guide plate 21 rotates synchronously with the swing blade 20 as it rotates around the preset swing center. When the guide plate 21 rotates, the angle between the inner wall of the window 11 and the guide plate 21 changes, and the direction of the airflow guided by the guide plate 21 and blown out of the window 11 changes accordingly.

[0033] The air outlet frame 10 is roughly a hollow, closed ring structure. The hollow channel enclosed by the air outlet frame 10 forms the air window 11, and the inner wall of the hollow channel is the inner wall of the air window 11. One end of the air outlet frame 10 is connected to the main unit 80 and fixed to the edge of the end opening of the air duct. The other end of the air outlet frame 10 protrudes outward from the main unit 80. The depth direction of the air window 11 is also the height direction of the air outlet frame 10. Specifically, the height direction of the air outlet frame 10 refers to the spacing direction between the two ends of the air outlet frame 10. In some embodiments, the height direction of the air outlet frame 10 is perpendicular to the installation surface of the air conditioning device. Taking a bathroom heater as an example, the air outlet frame 10 can be set on the air collection plate of the main unit 80, and the height direction of the air outlet frame 10 can be perpendicular to the air collection plate; for other air conditioning devices, the height direction of the air outlet frame 10 is perpendicular to the side of the main unit 80 where the air outlet frame 10 protrudes.

[0034] Specifically, when one side of the main unit 80 is installed on a vertical wall, one end of the air outlet frame 10 is connected to the other side of the main unit 80 facing away from the vertical wall, and the height direction of the air outlet frame 10 is a horizontal straight line perpendicular to the vertical wall; when the main unit 80 is installed on an indoor ceiling, one end of the air outlet frame 10 is connected to the other side of the main unit 80 facing away from the indoor ceiling, and the height direction of the air outlet frame 10 is a vertical straight line; when the main unit 80 is installed in a bathroom ceiling, one end of the air outlet frame 10 is connected to the side of the main unit 80 facing the ground, and the height direction of the air outlet frame 10 is a vertical straight line. If the air outlet frame 10 is cut by a plane parallel to the installation surface of the air conditioning equipment, the cross-sectional shape of the air outlet frame 10 obtained by the plane can be circular, oblong, rectangular, etc.

[0035] Taking a bathroom heater installed in the ceiling as an example, the main unit 80 includes a hollow casing and an air collecting plate covering the bottom of the casing. The air duct is located inside the casing, and the air collecting plate has an air outlet as the end opening of the air duct. The air collecting plate is parallel to the horizontal plane and perpendicular to the height direction of the air outlet frame 10. One end of the air outlet frame 10 is connected to the side of the air collecting plate facing away from the casing, and the other end protrudes from the side of the air collecting plate facing the ground. The air collecting plate and the air outlet frame 10 can be formed separately and then assembled and fixed, or they can be formed as a single piece.

[0036] The driving component 50 can either drive the swing blade 20 to rotate around a preset swing center at a certain angle and then stop, so that the air guide plate 21 and the inner wall of the air window 11 maintain a specific tilt angle, thereby allowing the air guide plate 21 to guide the airflow out of the air window 11 in a specific air guiding direction, so that the airflow blows the target at a specific position and direction, or drive the swing blade 20 to swing back and forth around the preset swing center within a certain angle range, so that the tilt angle between the air guide plate 21 and the inner wall of the air window 11 changes back and forth within a certain range, thereby obtaining the effect of dynamic swing blowing of airflow. Therefore, the target can be blown in a larger space by using dynamic swing airflow.

[0037] See Figure 4 In some embodiments, the drive unit 50 can also drive the swing blade 20 to rotate around a preset swing center until the air guide plate 21 covers the end of the air outlet frame 10 that is relatively far away from the main unit 80. At this time, the air guide plate 21 covers and closes the opening of the air window 11, and the air window 11 passes through the end of the air outlet frame 10 that is relatively far away from the main unit 80, thereby forming the aforementioned opening of the air window 11. When the air guide plate 21 covers the air outlet frame 10 and closes the opening of the air window 11, the airflow inside the air duct of the main unit 80 stops being transported and regulated, and the air conditioning equipment stops transporting airflow into the room. Closing the opening of the air window 11 can protect external dust, mist and other impurities from entering the air window 11 or even the air duct, and the air conditioning equipment is more aesthetically pleasing and tidy.

[0038] In some embodiments, the air control device also includes a face mask 70, see [reference] Figures 4-5 The face mask 70 is spaced apart from the side of the main unit 80 where the air outlet frame 10 is located. The distance between the face mask 70 and the side of the main unit 80 where the air outlet frame 10 is located is approximately equal to the height of the end of the air outlet frame 10 that is relatively far from the main unit 80. The face mask 70 can be equipped with lighting units, light-effect beauty units, display units, light-emitting heating units, etc. Optionally, such as... Figure 4 As shown, when the drive unit 50 drives the oscillating blade 20 to rotate until the air guide plate 21 covers the air outlet frame 10 and closes the air window 11 opening, the side of the air guide plate 21 facing away from the air outlet frame 10 and the main unit 80 is flush with the side of the mask 70 facing away from the main unit 80. This arrangement makes the air conditioning equipment more aesthetically pleasing and flat when the air conditioning and delivery function is stopped. It should be noted that the mask 70 is not a necessary component of the air conditioning equipment and can be omitted in other embodiments.

[0039] The swing assembly of this utility model also includes an output component 40 and an input component 30. The output component 40 is directly connected to the output end of the drive component 50 and can move with the output end in response to the power output of the drive component 50. The input component 30 is installed on the swing blade 20 and is directly or indirectly engaged with the output component 40. Direct engagement means that the input component 30 and the output component 40 are in direct contact and engaged. Indirect engagement means that there is one or more intermediate transmission elements between the input component 30 and the output component 40, and the input component 30 and the output component 40 are not in direct contact. Power is transmitted from the output end to the output component 40, the intermediate transmission elements, and the input component 30 in sequence. The engagement of the input component 30 and the output component 40 improves the response sensitivity of the swing blade 20 to the power output of the drive component 50. The transmission accuracy and transmission efficiency between the drive component 50 and the swing blade 20 are higher, and the movement error of the swing blade 20 when swinging around the preset swing center is lower. This enables precise adjustment of the airflow guiding effect of the air guide plate 21 to ensure that the airflow accurately blows and covers the target.

[0040] See Figure 2 , Figures 4-6 The page 20 also includes an inset edge 201, and the inset edge 201 can rotate with the page 20 around a preset swing center to point towards the host 80. For example... Figures 4-5As shown, when the flap 20 rotates so that the inlet edge 201 points towards the main unit 80, the inlet edge 201 is below the opening of the air vent 11, and the flap 20 extends into the air vent 11 to its maximum depth. In some embodiments, the end of the air outlet frame 10 through which the air vent 11 passes is a plane. When the inlet edge 201 rotates with the flap 20 to point towards the main unit 80, the inlet edge 201 is on the side of the plane where the opening of the air vent 11 is located, which is relatively closer to the main unit 80. At this time, a portion of the flap 20, including the inlet edge 201, extends into the air vent 11 and is located on the side of the plane where the opening of the air vent 11 is located, which is relatively closer to the main unit 80. In the state where the inlet edge 201 is below the opening of the air vent 11 and points towards the main unit 80, the maximum depth to which the flap 20 extends into the air vent 11 is the maximum distance from the inlet edge 201 to the opening of the air vent 11.

[0041] like Figure 2 , Figures 4-6 As shown, the air guide plate 21 includes a first side 211 and a second side 212 arranged opposite to each other, and the frame side 201 is formed by the first side 211. Taking a bathroom heater installed on the ceiling as an example, the main unit 80 includes an air collecting plate with an air outlet frame 10 and the air collecting plate is horizontally arranged facing the ground. When the swivel 20 rotates to the point where the air guide plate 21 covers the air outlet frame 10 and closes the air window 11 opening, the air guide plate 21 is parallel to the air collecting plate, and the area of ​​the air guide plate 21 projected onto the horizontal plane reaches its maximum. When the swivel 20 rotates to the point where the first side 211 points to the air collecting plate, the second side 212 points to the ground, and the distance from the second side 212 to the air window 11 opening and the distance from the second side 212 to the ground reach their maximum and minimum, respectively. The air guide plate 21 is inclined relative to the air collecting plate, and the area of ​​the air guide plate 21 projected onto the horizontal plane reaches its minimum. The airflow entering the air window 11 from the end opening of the air duct flows through the first side 211 and the second side 212 in sequence and is then blown into the room.

[0042] like Figures 4-5 As shown, the preset swing center, the output component 40, and the output end of the drive component 50 are all not higher than the opening of the air window 11. In some embodiments, the end of the air outlet frame 10 through which the air window 11 passes is a plane, and the preset swing center, the output component 40, and the drive component 50 are all located on the side of the plane where the opening of the air window 11 is located, which is relatively close to the main unit 80. With this setting, no matter how much the swing blade 20 rotates around the preset swing center, at least the preset swing center, the output component 40, and the output end of the drive component 50 have a definite position in the height direction of the air outlet frame 10, and will not occupy additional space in the height direction of the air outlet frame 10. When the air guide plate 21 rotates with the swing blade 20 to cover the air outlet frame 10 and close the opening of the air window 11, the output component 40 and the output end do not protrude from the air guide plate 21.

[0043] Furthermore, in some embodiments, the input component 30 and the output component 40 directly contact and engage. The maximum swing angle of the oscillating blade 20 around the preset swing center does not exceed 90°. Regardless of the swing angle of the oscillating blade 20, the inlet frame edge 201 is always located on the first half, and the second edge 212 is always located on the second half. The engagement position between the input component 30 and the output component 40 is also located on the second half. The first half and the second half are located on opposite sides of the dividing plane, which specifically refers to a plane passing through the preset swing center and parallel to the height direction of the air outlet frame 10. Taking a bathroom heater installed on the ceiling as an example, the preset swing center extends horizontally in a straight line and is located within the dividing plane, which is a vertically extending plane perpendicular to the air collecting plate. The dividing plane is in... Figures 4-5 The straight line indicated by arrow V represents the height direction of the air outlet frame 10. Figures 4-5 The arrow F is used to indicate this, and it is parallel to the center. Figures 4-5 The straight line indicated by the middle arrow V.

[0044] like Figure 4 As shown, when the air guide plate 21 rotates with the swing blade 20 to cover the air outlet frame 10 and close the air window 11 opening, the distance from the first side 211 to the preset swing center is less than the distance from the second side 212 to the preset swing center. The first side 211 and the second side 212 are located on both sides of the cutting surface, and the distance from the first side 211 to the cutting surface is less than the distance from the second side 212 to the cutting surface. With this configuration, the position of the preset swing center is closer to the inlet frame edge 201. When the swing blade 20 swings around the preset swing center, the rotation radius of the inlet frame edge 201 around the preset swing center is smaller. This makes the depth of the swing blade 20 extending into the air window 11 smaller when the inlet frame edge 201 points towards the main unit 80. The swing blade 20 is less likely to interfere with the main unit 80, which helps to reduce the height of the air outlet frame 10. This, in turn, reduces the size of the swing assembly along the height direction of the air outlet frame 10. The distance between the mask 70 and the main unit 80 can therefore be further reduced. The air conditioning device is more compact and occupies less space. When the air conditioning device is a bathroom heater installed in the bathroom ceiling, the height of the ceiling panel can be further raised, thereby significantly improving the user's head space.

[0045] for Figures 1-6 In the embodiment shown, the size of the swing assembly in the height direction of the air outlet frame 10 is reduced by 3mm to 20mm compared to existing similar products, and the size of the air control device in the height direction of the air outlet frame 10 ranges from 80mm to 180mm. The reduction in the height dimension of the entire device is considerable.

[0046] exist Figures 1-5In the illustrated embodiment, the driving component 50 includes a stepper motor fixed to the air outlet frame 10, and the output end of the driving component 50 is the output shaft of the stepper motor. The input component 30 includes an input gear 31 fixed to the oscillating flap 20, and the output component 40 includes an output gear 41 mounted on the output shaft of the stepper motor. The input gear 31 and the output gear 41 are in direct contact and meshing. The preset oscillation center coincides with the rotation center of the input gear 31. See [reference needed]. Figures 4-6 The letter R represents the preset swing center and the rotation center of the input gear 31. The axis of the stepper motor's output shaft coincides with the rotation center of the output gear 41. Any shortest line connecting the preset swing center to the rotation center of the output gear 41 is inclined relative to the air collecting plate, and this shortest line is located on the second half side. This arrangement achieves the goal of shortening the distance from the rotation center of the output gear 41 to the opening of the air window 11 by appropriately configuring the distance from the cutting surface to the rotation center of the output gear 41. The installation position of the stepper motor is therefore closer to the opening of the air window 11, which helps to reduce the overall size of the swing assembly in the height direction of the air outlet frame 10.

[0047] Optionally, in some embodiments, the radii of the input gear 31 and the output gear 41 are equal, and the driving member 50 is a stepper motor. With this configuration, the rotation angle of the output shaft of the stepper motor is equal to the rotation angle of the swing 20 around the preset swing center. A 1:1 transmission ratio is achieved from the driving member 50 to the swing 20. Therefore, a suitable stepper motor can be selected directly according to the step rotation angle of the swing 20.

[0048] Optionally, the plane containing the preset swing center and the rotation center of the output component 40 is inclined at an angle relative to the aforementioned dividing surface, with the angle ranging from 30° to 60°. The rotation center of the output component 40 is the rotation center of the output gear 41. This arrangement shortens the distance between the rotation center of the output gear 41 and the opening of the air vent 11, while also preventing the distance between the rotation center of the output gear 41 and the dividing surface from being too large. A suitable distance between the rotation center of the output gear 41 and the dividing surface avoids the output component 40 and the drive component 50 occupying excessive space in the width direction of the air outlet frame 10. Specifically, the width direction of the air outlet frame 10 refers to the direction perpendicular to the height of the air outlet frame 10 and parallel to the air collecting plate. Alternatively, the angle between the preset swing center and the rotation center of the output component 40 is less than 30° or greater than 60°.

[0049] Optionally, the swing assembly also includes a connection module 60, see [link / reference] Figures 2-3 , Figure 6The connecting module 60 includes a rotating shaft 61 and has screw holes 62 and positioning holes 63. The screw holes 62 allow screws to pass through, thus fixing the connecting module 60 and the air outlet frame 10 together. The positioning holes 63 are used to fix the connecting module 60 to the air outlet frame 10, thereby restricting the degree of freedom of rotation of the connecting module 60 relative to the air outlet frame 10, so that the connecting module 60 and the air outlet frame 10 are fixed as one unit. The rotating shaft 61 is used to rotate with the oscillating blade 20, and the preset oscillation center is formed by the axis of the rotating shaft 61. In other embodiments, the connecting module 60 is fixedly connected to the air outlet frame 10 by other types of fasteners, not limited to screws.

[0050] Optionally, the input gear 31 is an incomplete cylindrical gear with a locating surface 32. This incomplete cylindrical gear can be a bow gear or a sector gear. A bow gear or sector gear can be obtained by removing a portion of the complete cylindrical gear; the locating surface 32 is the cut surface formed after the machining process. Figures 1-2 , Figures 4-6 As shown, the output gear 41 is specifically a bow-shaped gear and the positioning surface 32 is a plane. In some embodiments, the positioning surface 32 is flush with the outer side of the air guide plate 21, while in other embodiments, the positioning surface 32 is lower than the outer side of the air guide plate 21. When the air guide plate 21 covers the air outlet frame 10 and closes the air window 11 as the flap 20 rotates, the side of the air guide plate 21 facing away from the air outlet frame 10 and the main unit 80 is the outer side of the air guide plate 21. Furthermore, when the positioning surface 32 is lower than the outer side of the air guide plate 21, the distance from the positioning surface 32 to the main unit 80 is slightly less than the distance from the outer side of the air guide plate 21 to the main unit 80.

[0051] This design further reduces the overall size of the swing assembly, particularly the height of the swing unit formed by the swing blade 20 and the input component 30. The height of the swing unit refers to the total dimension of the swing unit formed by the swing blade 20 and the input component 30 along the height of the air outlet frame 10 when the swing blade 20 rotates to the point where the air guide plate 21 covers the air outlet frame 10 and closes the air window 11. The angle at which the swing blade 20 swings around the preset swing center is limited; a bow-shaped gear or a sector gear can meet the rotation requirements of the swing blade 20.

[0052] Further, see Figures 1-2 , Figures 4-5The air outlet frame 10 includes a partition wall 12, which includes a wind window side wall 121. The wind window 11 is formed on one side of the wind window side wall 121. When the air guide plate 21 rotates with the swing blade 20 to cover the air outlet frame 10 and close the wind window 11, a part of the air guide plate 21 protrudes from the other side of the wind window side wall 121 to form a baffle 213. The baffle 213 is spaced apart from the main unit 80. Taking the air conditioning device as a bathroom heater installed on the ceiling of the bathroom as an example, when the air guide plate 21 covers the air outlet frame 10, the baffle 213 and the air collecting plate are spaced apart and facing each other. The bow-shaped gear, which is the input gear 31, is attached to the side of the baffle 213 facing the main unit 80 through the positioning surface 32. The side of the baffle 213 facing the main unit 80 is the part of the air guide plate 21 that protrudes from the wind window side wall 121 to cover the air outlet frame 10.

[0053] With this configuration, the positioning surface 32 of the input gear 31 is lower than the outer side of the air guide plate 21. When the air guide plate 21 covers the air outlet frame 10 and the air window 11 is closed, the difference between the distance from the positioning surface 32 to the main unit 80 and the distance from the outer side of the air guide plate 21 to the main unit 80 is the thickness of the air guide plate 21. The baffle 213 effectively shields the input gear 31, making the air conditioning equipment more aesthetically pleasing. It is understood that in other embodiments, the baffle 213 can be omitted, that is, the air guide plate 21 does not protrude from the side of the air window sidewall 121 facing away from the air window 11, and the positioning surface 32 is flush with and coplanar with the outer side of the air guide plate 21.

[0054] Furthermore, when the air guide plate 21 rotates with the swivel blade 20 to cover the air outlet frame 10 and close the air window 11, the output component 40 and the drive component 50 are both located within the gap area between the baffle 213 and the main unit 80, and the meshing position between the input gear 31 and the output gear 41 is also located within the gap area between the baffle 213 and the main unit 80. If the air conditioning device is observed from the side of the main unit 80 where the air outlet frame 10 is located, the drive component 50 and the output component 40 are both covered by the baffle 213. This arrangement makes the air conditioning device more aesthetically pleasing, increases the total length of the air guide plate 21, and allows the air guide plate 21, output component 40, drive component 50, and main unit 80 to be arranged sequentially along the height direction of the air outlet frame 10. The significance of the baffle 213 is that it can shield and protect the input gear 31, output gear 41, and drive component 50.

[0055] In some embodiments, the partition wall 12, in addition to the aforementioned windshield side wall 121, also includes a retaining wall 122 and a fitting wall 123, see reference. Figures 1-2 , Figures 4-5The enclosure wall 122 and the fitting wall 123 are both located on the side of the windshield side wall 121 facing away from the windshield 11. The enclosure wall 122, the fitting wall 123, and the windshield side wall 121 together form a storage cavity 13 located on the side of the windshield side wall 121 facing away from the windshield 11. The enclosure wall 122 extends along the edge of the windshield side wall 121, and the fitting wall 123 is bent and connected to the edge of the opening of the windshield 11, and the fitting wall 123 is approximately parallel to the air collecting plate. The output component 40 is rotatably installed in the storage cavity 13, and the drive component 50 is fixedly installed in the storage cavity 13. The partition wall 12 also has a through hole 14 connecting the ventilation window 11 and the storage cavity 13. The input gear 31 and the output gear 41 directly contact and mesh in the through hole 14. When the air guide plate 21 is placed over the air outlet frame 10 and the air window 11 is closed, the baffle 213 is attached to the attached wall 123, and the air guide plate 21 is approximately parallel to the air collecting plate.

[0056] With this configuration, the partition wall 12 can accommodate the output component 40 and the drive component 50 through the receiving cavity 13 to protect the output component 40 and the drive component 50, while ensuring that the input component 30 and the output component 40 are in normal contact and engagement.

[0057] Compared with the prior art, the swing assembly of this utility model has the following beneficial effects: the inlet edge 201 of the swing blade 20 no longer swings around the output end of the drive component 50, but swings around a preset swing center that is closer to the inlet edge 201. When the swing blade 20 rotates around the preset swing center until the inlet edge 201 points to the main unit 80, the inlet edge 201 is closer to the opening of the air window 11, that is, the size of the swing blade 20 extending into the air window 11 is smaller. Therefore, the depth of the air window 11 can be reduced so that the air outlet frame 10 is lower. The lower air outlet frame 10 means that the height of the air conditioning device is smaller, the installation gap between the mask 70 and the main unit 80 is narrowed, and the space occupied by the air conditioning device is less. This solves the problem of existing similar products occupying a large installation space and a lot of storage space. Therefore, the air conditioning device of this utility model is more user-friendly for installation and use, as well as for the storage of manufacturers and distributors.

[0058] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
