Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an energy-saving variable airflow multi-channel air conditioning unit. Background Technology

[0002] With the improvement of people's living standards and the diversification of industrial production demands, air conditioning systems, as key equipment for regulating indoor temperature and humidity, have seen performance optimization and energy-saving upgrades become the core direction of industry development. Among them, multi-channel air conditioning units are widely used in large shopping malls, office buildings, industrial workshops, and other scenarios because they can achieve precise air delivery to different areas.

[0003] However, existing multi-channel air conditioning units still have many technical challenges in actual operation:

[0004] Low airflow efficiency and high energy consumption: Traditional multi-channel air conditioners often use single or simply combined air guide plates with poor coordination between them. The abrupt turns in the airflow create significant air resistance within the unit. To overcome this resistance, the fan must maintain high power operation, increasing energy consumption and potentially generating noise due to turbulent airflow, negatively impacting the user experience. Furthermore, excessive air resistance reduces heat exchange efficiency, significantly diminishing the cooling or heating performance of the air conditioning unit.

[0005] Interference between multiple channels and poor independent control: Existing multi-channel air conditioners often have design flaws in the air guide structure of each outlet. When one channel is activated, the stationary air guides in other channels can easily obstruct the airflow, causing some airflow to backflow or become erratic, failing to accurately deliver air to the target area. In addition, the tilt angle adjustment of the air guides is mostly controlled in a single dimension, making it difficult to create a smooth transition airflow according to the air outlet requirements of different channels, further exacerbating the mutual interference between channels.

[0006] Complex air guide vane drive and coordination adjustment mechanisms: To achieve multi-channel variable airflow, some air conditioning units employ complex drive mechanisms, leading to increased equipment failure rates and maintenance costs. Furthermore, most drive mechanisms struggle to achieve synchronous and precise adjustment of multiple air guide vanes, resulting in low matching of vane tilt angles and an inability to form a continuous and smooth airflow path, thus affecting the uniformity and stability of air delivery.

[0007] Therefore, how to design an air conditioning unit that can achieve independent and smooth airflow in each channel while reducing energy consumption has become an urgent problem to be solved by those skilled in the art.

[0008] This invention addresses the shortcomings of the existing technology by proposing an energy-saving variable airflow multi-channel air conditioning unit. By optimizing the structure of the air guide component and the drive coordination mechanism, the air guide smoothness is improved and the operating energy consumption is reduced. Summary of the Invention

[0009] In order to overcome the shortcomings of the prior art, the present invention provides an energy-saving variable air multi-channel air conditioning unit with the advantage of smooth airflow.

[0010] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving variable air multi-channel air conditioning unit, comprising: an air conditioning casing;

[0011] The first air guide assembly includes a support plate, which is horizontally fixed inside the air conditioner housing. The support plate has four trapezoidal ventilation holes, and the bottom of the support plate is rotatably connected to four first air guide plates adapted to the trapezoidal ventilation holes via coil springs.

[0012] The second air guide assembly includes a column whose bottom end is fixed to the center of the support plate, a support seat fixed to the top of the column, a rotating ball rotating inside the support seat, a second air guide plate fixedly connected to the rotating ball via a connecting block, and four support rods supporting the second air guide plate rotatably connected to the periphery of the column via coil springs.

[0013] Four drive components are provided, which are used to drive the first air guide plate and the second air guide plate to tilt simultaneously, so that the extension line of the tilted second air guide plate passes through the inclined surface of the tilted first air guide plate.

[0014] In a preferred embodiment of the present invention, four drive components are respectively located on the four inner sidewalls of the air conditioner housing. Each drive component includes an electric telescopic rod, which is fixed inside the air conditioner housing. A base plate is fixed to the telescopic end of the electric telescopic rod, and a first toothed plate is vertically fixed to the base plate. A rotating shaft is rotatably connected inside the air conditioner housing, and a first gear and a second gear are fixedly sleeved on the rotating shaft. A fixed support plate is fixed to the inner wall of the air conditioner housing, and a T-shaped sliding plate slides vertically inside the fixed support plate. A vertical second toothed plate is fixed to the T-shaped sliding plate. The diameter of the first gear is three times the diameter of the second gear. The first gear meshes with the second toothed plate, and the second gear meshes with the first toothed plate. A pressing column is vertically fixed to the second toothed plate.

[0015] As a preferred embodiment of the present invention, the drive assembly further includes a curved tube fixed inside the air conditioner housing. The curved tube smoothly transitions between a vertical section and an inclined section. A through-plate slides through the inclined section. A follower column parallel to the inclined section is fixed on the through-plate. A pressing column is fixed at one end of the follower column that passes through the inclined section. The end of the pressing column away from the second toothed plate is inserted into the vertical section. The interior of the curved tube, located between the pressing column and the through-plate, is filled with lightweight balls. A support is fixed at the end of the inclined section. A guide column parallel to the vertical section is fixed on the support. The end of the guide column away from the support passes through the through-plate. A return spring is sleeved on the outside of the guide column, located between the through-plate and the support.

[0016] As a preferred embodiment of the present invention, when the first air guide plate is not subjected to downward pressure, the first air guide plate blocks the trapezoidal ventilation hole; when the first air guide plate is subjected to downward pressure, the first air guide plate tilts and opens.

[0017] As a preferred embodiment of the present invention, when the second air guide plate is not compressed, the second air guide plate is in a horizontal state due to the support of the four supporting rotating rods.

[0018] As a preferred embodiment of the present invention, the top of the air conditioner housing is provided with an air inlet, and the bottom of the four sides of the air conditioner housing are provided with air outlets.

[0019] As a preferred embodiment of the present invention, it further includes a suction fan, which is fixed at the air inlet on the air conditioner housing and guides the air vertically downward. A funnel-shaped air guide tube for concentrating air is fixed at the bottom of the suction fan.

[0020] As a preferred embodiment of the present invention, it further includes a surface cooler, which is fixed directly below the funnel-shaped air duct and is used for heat exchange.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention, through the configuration of the driving component, enables the second toothed plate to move upward a distance three times the downward movement distance of the base plate while simultaneously pressing the first air guide plate downward to open the trapezoidal ventilation holes. This significantly increases the downward stroke of the pressing column, resulting in a greater tilt angle of the second air guide plate being pressed by the pressing column than that of the first air guide plate being pressed by the base plate. Consequently, the extension line of the tilted second air guide plate passes through the inclined surface of the tilted first air guide plate, thus forming a... Figure 11 The airflow direction shown, through the two airflow guides of the second air guide plate and the first air guide plate, allows the air after heat exchange to be smoothly discharged from the corresponding air outlet, thereby improving the exhaust effect.

[0023] 2. In this invention, when the second air guide plate is not compressed, the pressure column and the second air guide plate are located on both sides of the vertical dotted line. When one of the pressure columns compresses the second air guide plate, the other three pressure columns will not be affected by the rotation of the second air guide plate. In addition, the extended dotted line of the downward compression direction of the pressure column passes through the upper surface of the second air guide plate. When the pressure column is compressed, it can compress the second air guide plate downwards, thereby achieving compression of the second air guide plate. This invention sets up four air guide channels. When one air guide channel is guiding air, the other three will not affect it, thereby avoiding the air guide being affected.

[0024] 3. When the pressing column of the present invention presses the upper surface of the second air guide plate, it makes line-to-surface contact with the upper surface of the second air guide plate, rather than point-to-surface contact. Line-to-surface contact pressing can ensure the smooth downward tilting of the second air guide plate and avoid the problem of left-right swaying during the pressing of the pressing column on the second air guide plate. If the second air guide plate sways left-right, it will affect the air guiding and make it difficult for the air to be discharged smoothly. Attached Figure Description

[0038] like Figures 1 to 11 As shown, the present invention provides an energy-saving variable airflow multi-channel air conditioning unit, comprising:

[0039] Air conditioner housing 1, the top of the air conditioner housing 1 is provided with an air inlet 11, and the bottom of the four sides of the air conditioner housing 1 are provided with air outlets 12;

[0040] The suction fan 2 is fixed at the air inlet 11 on the air conditioner housing 1, and the suction fan 2 guides the air vertically downward. The bottom of the suction fan 2 is fixed with a funnel-shaped air guide tube for concentrating the air.

[0041] The surface cooler 3 is fixed directly below the funnel-shaped air duct and is used for heat exchange. The surface cooler 3 adopts a copper-aluminum composite fin structure with a heat exchange area of ​​15-20㎡. It achieves air heat exchange through refrigerant circulation. Its installation position is aligned with the lower end of the funnel-shaped air duct, and the distance between the two is maintained at 50-80mm. This avoids airflow short-circuiting and ensures that the airflow coverage rate after passing through the surface cooler is more than 95%.

[0042] The first air guide assembly 4 includes a support plate 41, which is horizontally fixed inside the air conditioner housing 1 and located directly below the surface cooler 3. The support plate 41 has four trapezoidal ventilation holes. The bottom of the support plate 41 is rotatably connected to four first air guide plates 42 that are adapted to the trapezoidal ventilation holes by a coil spring. When the first air guide plates 42 are not subjected to downward pressure, the first air guide plates 42 block the trapezoidal ventilation holes. When the first air guide plates 42 are subjected to downward pressure, the first air guide plates 42 tilt and open.

[0043] The second air guide assembly 5 includes a column 51 with its bottom end fixed to the center of the support plate 41, a support seat 52 fixed to the top of the column 51, a rotating ball 53 rotating inside the support seat 52, a second air guide plate 55 fixedly connected to the rotating ball 53 via a connecting block 54, and four support rods 56 supporting the second air guide plate 55 rotatably connected to the periphery of the column 51 via coil springs. When the second air guide plate 55 is not compressed, it is in a horizontal state due to the support of the four support rods 56.

[0044] Four drive components 6 are provided, each used to drive the first air guide plate 42 and the second air guide plate 55 to tilt simultaneously, until the extension line of the tilted second air guide plate 55 passes through the inclined surface of the tilted first air guide plate 42. The four drive components 6 are located on the four inner walls of the air conditioner housing 1. Each drive component 6 includes an electric telescopic rod 61, which is fixed inside the air conditioner housing 1. A base plate 62 is fixed to the telescopic end of the electric telescopic rod 61, and a first toothed plate 63 is vertically fixed on the base plate 62. A rotating shaft is rotatably connected inside the air conditioner housing 1, and a first gear 64 and a second gear 65 are fixedly sleeved on the rotating shaft. A fixed support plate 66 is fixed to the inner wall of the air conditioner housing 1, and a T-shaped sliding plate 67 slides vertically inside the fixed support plate 66. A vertical second toothed plate 68 is fixed on the T-shaped sliding plate 67. The diameter of the first gear 64 is three times the diameter of the second gear 65. The first gear 64 and the second gear 65... Two toothed plates 68 are meshed together, the second gear 65 is meshed with the first toothed plate 63, and a pressing column 69 is vertically fixed on the second toothed plate 68. The drive assembly 6 also includes a bent tube 70 fixed inside the air conditioner housing 1. The bent tube 70 is smoothly transitioned between a vertical section and an inclined section. A through plate 71 slides through the inclined section. A follower column 72 parallel to the inclined section is fixed on the through plate 71. A pressing column 73 is fixed at one end of the follower column 72 that passes through the inclined section. The end of the pressing column 69 away from the second toothed plate 68 is inserted into the vertical section. The inside of the bent tube 70 and between the pressing column 69 and the through plate 71 is filled with lightweight balls 74. A support 75 is fixed at the end of the inclined section. A guide column 76 parallel to the vertical section is fixed on the support 75. The end of the guide column 76 away from the support 75 passes through the through plate 71. A return spring 77 is sleeved on the outside of the guide column 76 and between the through plate 71 and the support 75.

[0045] Workflow and airflow path optimization

[0046] Startup Phase

[0047] After the suction fan 2 is started, outside air enters through the air inlet 11, is gathered by the funnel-shaped air guide tube, and blows vertically downwards towards the surface cooler 3. After heat exchange, it forms cold air and continues to enter the space between the first air guide assembly 4 and the second air guide assembly 5.

[0048] Airflow control stage

[0049] When air needs to be supplied from one of the air outlets 12, the corresponding drive component 6 is activated:

[0050] The electric telescopic rod 61 extends, pushing the base plate 62 downward by 20-30mm, squeezing the first air guide plate 42 to overcome the spring force and tilting it open at an angle of 15°-20°, thus opening the trapezoidal ventilation hole.

[0051] At the same time, the first toothed plate 63 moves down with the bottom plate, and through gear transmission, drives the second toothed plate 68 to move up by 60-90mm, squeezing the lightweight ball 74 in the bend 70, pushing the pressure column 73 to move obliquely downward in a 45° direction by 40-50mm, squeezing the second air guide plate 55 to tilt at an angle of 30°-40°.

[0052] Since the second air guide plate has a greater tilt angle than the first air guide plate, its extension line precisely connects with the slope of the first air guide plate, forming a "secondary air guide channel" as shown in Figure 11. After the cold air is guided by the second air guide plate, it flows smoothly along the slope of the first air guide plate to the corresponding air outlet 12, improving the air delivery efficiency.

[0053] Reset phase

[0054] After the air supply ends, the electric telescopic rod 61 retracts, the base plate 62 and the lower pressure column 73 retract, and the first air guide plate 42 and the second air guide plate 55 quickly reset under the action of the spring force, sealing the trapezoidal ventilation hole and restoring the horizontal state to avoid airflow interference between different channels.

[0055] Strengthening the principles and advantages of energy saving

[0056] Energy saving in variable air ducts

[0057] By independently controlling four drive components, flexible air supply in single-channel, dual-channel, or multi-channel configurations can be achieved, such as opening only the air outlets corresponding to the personnel activity area, which reduces energy consumption compared to traditional units that supply air from all four sides simultaneously.

[0058] Structural optimization and energy saving

[0059] The combination of trapezoidal ventilation holes and air guide plates reduces wind resistance and lowers the power consumption of the suction fan.

[0060] The angle linkage design between the second air guide plate and the first air guide plate improves airflow guidance efficiency and reduces ineffective circulation energy consumption.

[0061] Sealed design for energy saving

[0062] Unopened channels are sealed by the first air guide plate to prevent cold air from escaping from non-target areas, further reducing cooling loss.

[0063] This invention achieves the dual goals of multi-channel precise air delivery and high-efficiency energy saving by refining structural parameters, optimizing material selection, and strengthening airflow control. It is suitable for the zoned air conditioning needs of large spaces such as offices and shopping malls.

[0064] When the energy-saving variable air multi-channel air conditioning unit of the present invention is required, the electric telescopic rod 61 at the corresponding position of the air duct to be supplied with air is first activated. The telescopic end of the electric telescopic rod 61 drives the base plate 62 to move downward. The downward movement of the base plate 62 compresses the first air guide plate 42 and tilts it downward. At this time, the trapezoidal ventilation hole opens. At the same time as the base plate 62 moves downward, it drives the first toothed plate 63 to move downward. Since the first toothed plate 63 is meshed with the second gear 65, and the first gear 64 is meshed with the second toothed plate 68, the first gear 64 and the second gear 65 rotate coaxially. The diameter of the first gear 64 is three times the diameter of the second gear 65. Therefore, when the first toothed plate 63 moves downward, the second toothed plate 68 rotates coaxially with the second gear 65. The upward movement distance of the second toothed plate 68 is three times the downward movement distance of the first toothed plate 63. The second toothed plate 68 drives the extrusion column 69 to move upward, and the extrusion column 69 extrudes the lightweight ball 74, thereby causing the through plate 71, follower column 72, and pressure column 73 to move obliquely downward along the length of the inclined section. When the pressure column 73 moves obliquely downward along the length of the inclined section, it compresses the second guide plate 55 to tilt. Since the upward movement distance of the second toothed plate 68 is three times the downward movement distance of the first toothed plate 63, the tilt angle of the second guide plate 55 is greater than the tilt angle of the first guide plate 42, so that the extension line of the tilted second guide plate 55 passes through the inclined surface of the tilted first guide plate 42, thus forming a... Figure 11 The airflow direction shown is from the present invention Figure 4 As can be seen, when the second air guide plate 55 is not compressed, the pressing column 73 and the second air guide plate 55 are located on both sides of the vertical dotted line. That is to say, when one of the pressing columns 73 compresses the second air guide plate 55, the other three pressing columns 73 will not be affected by the rotation of the second air guide plate 55. In addition, from the present invention... Figure 4 As can be seen, the extended dotted line of the downward squeezing direction of the pressure column 73 passes through the upper surface of the second air guide plate 55. That is to say, when the pressure column 73 is squeezed, it can squeeze the second air guide plate 55 downwards, thereby achieving the squeezing of the second air guide plate 55.

[0065] By configuring the drive assembly 6, this invention enables the second toothed plate 68 to move upward a distance three times the downward movement distance of the base plate 62 while the base plate 62 presses down on the first air guide plate 42 to open the trapezoidal ventilation holes. This significantly increases the downward stroke of the pressing column 73, resulting in a greater tilt angle of the second air guide plate 55 pressed by the pressing column 73 than that of the first air guide plate 42 pressed by the base plate 62. Consequently, the extension line of the tilted second air guide plate 55 passes through the inclined surface of the tilted first air guide plate 42, thus forming a... Figure 11The airflow direction shown, through the two-stage airflow guidance of the second air guide plate 55 and the first air guide plate 42, allows the air after heat exchange to be smoothly discharged from the corresponding air outlet 12, thereby improving the exhaust effect. In this invention, when the second air guide plate 55 is not compressed, the downward pressure column 73 and the second air guide plate 55 are located on both sides of the vertical dotted line. When one of the downward pressure columns 73 compresses the second air guide plate 55, the other three downward pressure columns 73 will not be affected by the rotation of the second air guide plate 55. Furthermore, the extended dotted line of the downward compression direction of the downward pressure column 73 passes through the upper surface of the second air guide plate 55. When the downward pressure column 73 is compressed, it can compress the second air guide plate 55 diagonally downwards, thus achieving compression of the second air guide plate 55. This invention provides four airflow channels; when one airflow channel is guiding airflow, the other three will not affect it, thereby avoiding interference with airflow guidance. When the pressing column 73 of the present invention presses the upper surface of the second air guide plate 55, it makes line-to-surface contact with the upper surface of the second air guide plate 55, rather than point-to-surface contact. Line-to-surface contact pressing can ensure the smooth downward tilting of the second air guide plate 55 and avoid the problem of left-right swaying during the pressing process of the pressing column 73 pressing the second air guide plate 55. If the second air guide plate 55 sways left-right, it will affect the air guiding and make it difficult for the air to be discharged smoothly.
