Description

Technical Field

[0001] This invention relates to the field of central air conditioning vent technology, specifically an air conditioning vent grille. Background Technology

[0002] Traditional decorative air conditioning vents often use linear designs, which are aesthetically pleasing, but these vents are either not adjustable or require manual adjustment, making them inconvenient to use, unable to change the airflow direction in a timely manner, and resulting in increased energy consumption due to unreasonable airflow organization, as well as a poor user experience. Traditional electrically adjustable vents are usually manufactured by air conditioning manufacturers to match the indoor unit, which cannot match the long and narrow vent designs of decorations, and the electric louvers are directly exposed, which has low user acceptance. Therefore, this application proposes an energy-saving, comfortable, adjustable air conditioning air outlet grille that matches the decoration. Summary of the Invention

[0003] The purpose of this invention is to provide an air conditioning vent grille to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an air conditioning vent grille, comprising a housing, wherein a horizontal rotating shaft is uniformly arranged inside the housing along the axial direction, an up-and-down air sweeping assembly is provided on the front side of the horizontal rotating shaft, and a horizontal air sweeping assembly is provided on the rear side of the horizontal rotating shaft.

[0005] The upper and lower air sweeping assembly includes upper and lower air sweeping louvers arranged horizontally from top to bottom. The front side of the horizontal rotating shaft is provided with hinge seats at equal intervals from top to bottom. The rear side of the upper and lower air sweeping louvers is rotatably mounted on the hinge seats. The upper and lower air sweeping louvers rotate around the hinge seats in the upper and lower directions.

[0006] The up-and-down air sweeping assembly also includes a first stepper motor and a vertically arranged support plate fixedly installed on the housing, and the output end of the first stepper motor is provided with a transmission plate; The support plate has upper and lower rotating shafts rotatably mounted at equal intervals from top to bottom on its back side, and the front side of one end of the upper and lower sweeping louvers is rotatably mounted on the support plate via the upper and lower rotating shafts. One of the upper and lower rotating shafts is provided with a drive shaft at one end, and the end of the drive plate is rotatably connected to the drive shaft.

[0007] The outer casing has an arc-shaped groove on one side that matches the rotation trajectory of the drive shaft.

[0008] The horizontal sweeping assembly includes horizontal sweeping louvers that are equally spaced along the axial direction. The horizontal sweeping louvers are vertically arranged and rotatably mounted on the horizontal rotating shaft at their rear side. The horizontal sweeping louvers rotate horizontally around the horizontal rotating shaft.

[0009] The horizontal sweeping assembly further includes a second stepper motor fixedly mounted on the housing and a horizontally arranged transmission rod, wherein the output end of the second stepper motor is provided with a vertical shaft; All of the horizontally swept louvers are rotatably connected to the transmission rod at their front sides. The vertical shaft end is provided with a connecting plate, and the end of the connecting plate is rotatably connected to a transmission connecting rod. The end of the transmission connecting rod is rotatably connected to the end of the transmission rod.

[0010] The outer casing has a clearance groove on one side for the movement of the transmission link.

[0011] It also includes: a decorative frame, which matches the reserved central air conditioning vent, and the air conditioning vent grille is installed inside the decorative frame.

[0012] The decorative frame has multiple fine grid strips evenly spaced from top to bottom on its front side, and multiple inner support strips evenly spaced along the axial direction on its front side to support the fine grid strips.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention achieves automatic and flexible bidirectional adjustment of the central air conditioning outlet by setting up an up-and-down air-sweeping component and a horizontal air-sweeping component. In this invention, the vertical air-sweeping assembly utilizes a first stepper motor to drive a transmission plate, thereby causing the vertical air-sweeping louvers to rotate vertically, effectively adjusting the vertical airflow direction of the air outlet. The horizontal air-sweeping assembly, on the other hand, uses a second stepper motor to drive a vertical shaft, and through the linkage of a connecting plate and a transmission rod, causes the horizontal air-sweeping louvers to rotate horizontally, thus adjusting the horizontal airflow direction of the air outlet. This not only improves the adjustment flexibility of the central air conditioning outlet but also avoids the problems of traditional electric adjustable air outlets being unable to match the shape of long, open-plan air outlets and the electric louvers being directly exposed, greatly enhancing practicality. This invention combines horizontally swept louvers and vertically swept louvers to achieve built-in three-dimensional spatial air outlet adjustment, which can conveniently adjust any air outlet direction. When blowing hot air in winter, the direction of the air can be adjusted to blow downwards or towards people, which can quickly raise the indoor temperature or warm the human body, thereby achieving energy saving and improving comfort. When blowing cold air in summer, the direction of the air can be adjusted to blow upwards or away from people, which can quickly lower the indoor temperature and avoid causing discomfort, thereby achieving energy saving and improving comfort. This invention installs the decorative frame on the reserved central air conditioning vent, and the air conditioning vent grille is detachably installed inside the decorative frame, achieving technical separation between the air conditioning vent grille and the decorative frame without affecting the overall decorative effect.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Please see Figure 1-9 This invention provides a technical solution: an air conditioning vent grille, including a housing 10. During interior decoration, a central air conditioning vent matching the size of a decorative frame 50 is reserved at the ceiling position. The decorative frame 50 is installed at the reserved central air conditioning vent, and the air conditioning vent grille is detachably installed inside the decorative frame, achieving technical separation between the air conditioning vent grille and the decorative frame without affecting the overall decorative effect. At the same time, installation space is reserved to ensure that the first stepper motor 31 and the second stepper motor 41 can be installed normally. The housing 10 is securely installed at the reserved vent position, ensuring a perfect fit with the ceiling, which is both beautiful and practical.

[0018] The outer casing 10 has a horizontal rotating shaft 20 evenly arranged along the axial direction inside. The horizontal rotating shaft 20 has an upper and lower air sweeping assembly 30 on the front side and a horizontal air sweeping assembly 40 on the rear side. By setting the upper and lower air sweeping assembly 30 and the horizontal air sweeping assembly 40, the automatic and flexible bidirectional adjustment of the central air conditioning outlet is realized.

[0019] The upper and lower air sweeping assembly 30 includes upper and lower air sweeping louvers 33 arranged horizontally from top to bottom. A hinge seat 35 is provided at equal intervals from top to bottom on the front side of the horizontal rotating shaft 20. The upper and lower air sweeping louvers 33 are rotatably mounted on the hinge seat 35 on the rear side. The upper and lower air sweeping louvers 33 rotate around the hinge seat 35 in the upper and lower direction. The upper and lower air sweeping assembly 30 also includes a first stepper motor 31 fixedly mounted on the outer casing 10 and a vertically arranged support plate 34. A transmission plate 32 is provided at the output end of the first stepper motor 31. Upper and lower rotating shafts 36 are rotatably mounted at equal intervals from top to bottom on the back of the support plate 34. The front side of one end of the upper and lower air sweeping louvers 33 is rotatably mounted on the support plate 34 through the upper and lower rotating shafts 36. A transmission shaft 37 is provided at the end of one of the upper and lower rotating shafts 36. The end of the transmission plate 32 is rotatably connected to the transmission shaft 37.

[0020] Specifically, when it is necessary to adjust the up and down airflow direction of the air outlet, the first stepper motor 31 is started. The first stepper motor 31 drives the transmission plate 32 to rotate. Since the end of the transmission plate 32 is rotatably connected to the transmission shaft 37, and the transmission shaft 37 is located at the end of the upper and lower rotating shaft 36, and the front side of one end of the upper and lower sweeping louvers 33 is rotatably mounted on the support plate 34 through the upper and lower rotating shaft 36, the rotation of the transmission plate 32 will drive the upper and lower rotating shaft 36 to rotate, thereby driving the upper and lower sweeping louvers 33 to rotate around the hinge seat 35 in the up and down direction, thereby realizing the effective adjustment of the up and down airflow direction of the air outlet.

[0021] The outer casing 10 has an arc-shaped groove 38 on one side that matches the rotation trajectory of the drive shaft 37. The arc-shaped groove 38 provides movement space for the drive shaft 37, ensuring that when the first stepper motor 31 drives the transmission plate 32 to rotate the drive shaft 37, the drive shaft 37 can smoothly make circular motion within the arc-shaped groove 38 without jamming or interference due to space limitations. This ensures that the upper and lower air-sweeping louvers 33 can rotate stably and accurately around the hinge seat 35 in the upper and lower directions, achieving precise adjustment of the upper and lower airflow direction of the air outlet.

[0022] The horizontal sweeping assembly 40 includes horizontal sweeping louvers 44 evenly spaced along the axial direction. The horizontal sweeping louvers 44 are vertically arranged and rotatably mounted on a horizontal rotating shaft 20 at their rear sides. The horizontal sweeping louvers 44 rotate horizontally around the horizontal rotating shaft 20. The horizontal sweeping assembly 40 also includes a second stepper motor 41 fixedly mounted on the housing 10 and a horizontally arranged transmission rod 45. The output end of the second stepper motor 41 is provided with a vertical shaft 42. The front sides of all the horizontal sweeping louvers 44 are rotatably connected to the transmission rod 45. The end of the vertical shaft 42 is provided with a connecting plate 43. The end of the connecting plate 43 is rotatably connected to a transmission connecting rod 46. The end of the transmission connecting rod 46 is rotatably connected to the end of the transmission rod 45.

[0023] Specifically, when it is necessary to adjust the horizontal airflow direction of the air outlet, the second stepper motor 41 is started. The second stepper motor 41 drives the vertical shaft 42 to rotate, the vertical shaft 42 drives the connecting plate 43 to rotate, and the connecting plate 43 drives the transmission rod 45 to perform reciprocating linear motion through the transmission connecting rod 46. Since the front side of all the horizontally swept louvers 44 is rotatably connected to the transmission rod 45, the reciprocating linear motion of the transmission rod 45 will drive the horizontally swept louvers 44 to rotate around the horizontal rotating shaft 20 in the horizontal direction, thereby achieving effective adjustment of the horizontal airflow direction of the air outlet.

[0024] One side of the outer casing 10 has a clearance groove for the movement of the transmission link 46. The clearance groove provides movement space for the transmission link 46, ensuring that when the second stepper motor 41 drives the vertical shaft 42 to move the connecting plate 43, the transmission link 46 and the transmission rod 45, the transmission link 46 can move smoothly in the clearance groove without jamming or interference due to space limitations. This ensures that the horizontal sweeping louver 44 can rotate stably and accurately around the horizontal rotating shaft 20 in the horizontal direction, achieving precise adjustment of the horizontal airflow direction of the air outlet.

[0025] This also includes: a decorative frame 50, which matches the reserved central air conditioning vent, and an air conditioning vent grille installed inside the decorative frame 50; during interior decoration, a central air conditioning vent matching the size of the decorative frame 50 is pre-reserved at the ceiling position, the decorative frame 50 is precisely installed at the reserved position, and then the air conditioning vent grille is detachably installed inside the decorative frame 50. This design achieves technical separation between the air conditioning vent grille and the decorative frame, which not only does not adversely affect the overall decorative effect, but also reserves sufficient installation space to ensure that the first stepper motor 31 and the second stepper motor 41 can be installed smoothly, while allowing the outer casing 10 to be stably installed at the reserved vent position, perfectly integrating with the ceiling, combining aesthetics and practicality.

[0026] The decorative frame 50 features multiple fine grille strips 51 spaced evenly from top to bottom on its front side, and multiple inner support strips 52 spaced evenly along the axial direction on its front side to support the fine grille strips 51. The fine grille strips 51 not only enhance the aesthetics of the decorative frame 50 but also, to some extent, prevent large dust particles from entering the air conditioning vent grille, providing initial dust protection. The inner support strips 52 provide stable support for the fine grille strips 51, ensuring that they will not deform or be damaged by external forces during long-term use, thus guaranteeing the overall structural stability and durability of the decorative frame 50.

[0027] Working principle: When in use, first, according to the interior decoration, reserve a central air conditioning vent in the ceiling that matches the size of the decoration frame 50, install the decoration frame 50 in the reserved central air conditioning vent, and the air conditioning vent grille can be detachably installed in the decoration frame. When adjusting the airflow direction of the air outlet, to adjust the vertical airflow, the first stepper motor 31 is activated. The first stepper motor 31 drives the transmission plate 32 to rotate, which in turn drives the transmission shaft 37 to rotate in a circular motion within the arc-shaped groove 38. The transmission shaft 37 drives the upper and lower rotating shafts 36 to rotate, which in turn drives the upper and lower sweeping louvers 33 to rotate around the hinge seat 35 in the vertical direction, thus adjusting the vertical airflow direction of the air outlet. To adjust the horizontal airflow, the second stepper motor 41 is activated. The second stepper motor 41 drives the vertical shaft 42 to rotate, which in turn drives the connecting plate 43 to rotate. The connecting plate 43, through the transmission connecting rod 46, drives the transmission rod 45 to reciprocate linearly within the allowable range of the clearance groove. The transmission rod 45 drives the horizontal sweeping louvers 44 to rotate around the horizontal rotating shaft 20 in the horizontal direction, thus adjusting the horizontal airflow direction of the air outlet. This achieves automatic and flexible bidirectional adjustment of the central air conditioning outlet, improving its practicality.
