Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and more particularly to an energy-saving variable airflow multi-channel air conditioning unit. Background Art

[0002] With the improvement of people's quality of life and the diversification of industrial production needs, air conditioning systems, as key equipment for regulating indoor temperature and humidity, are facing a core focus on performance optimization and energy-saving upgrades. Multi-channel air conditioning units, which can achieve precise air delivery to different areas, are widely used in large shopping malls, office buildings, industrial workshops, and other scenarios.

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

[0004] Low airflow efficiency and high energy consumption: Traditional multi-channel air conditioners often utilize single or simply assembled air guides. These lack coordination and create abrupt turns in the air ducts, leading to significant air resistance within the unit. To overcome this resistance, the fan must operate at a high power level, increasing energy consumption and potentially creating noise due to airflow disturbances, impacting the user experience. Excessive air resistance also reduces heat exchange efficiency, significantly compromising the cooling or heating performance of the air conditioner.

[0005] Mutual interference between multiple channels and poor independent control: Existing multi-channel air conditioners often suffer from interlocking design flaws in the air guide structures of their outlets. When one channel is open to guide air, the static guides in other channels can easily block airflow, causing some airflow to backflow or scatter, preventing precise delivery to the target area. Furthermore, the guide angle adjustment is often single-dimensional, making it difficult to create a smooth transition between air ducts based on the airflow requirements of different channels, further exacerbating mutual interference between channels.

[0006] Complex drive and coordinated adjustment mechanisms for air deflectors: To achieve multi-channel variable airflow, some air conditioning units employ complex drive mechanisms, increasing equipment failure rates and maintenance costs. Furthermore, most drive mechanisms struggle to synchronize and precisely adjust multiple air deflectors, resulting in poorly matched tilt angles and a failure to create a continuous, smooth airflow path, impacting the uniformity and stability of air delivery.

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

[0008] In response to the above-mentioned deficiencies in the existing technology, the present invention proposes an energy-saving variable airflow multi-channel air-conditioning unit, which improves the smoothness of air guidance and reduces operating energy consumption by optimizing the structure of the air guide components and the driving coordination mechanism.

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

[0014] As a preferred technical solution of the present invention, four drive components are respectively located on the four inner side walls of the air-conditioning casing, and the drive component includes an electric telescopic rod, which is fixed in the air-conditioning casing, and the telescopic end of the electric telescopic rod is fixed with a base plate, and a first gear plate is vertically fixed on the base plate. The internal rotation of the air-conditioning casing is connected with a rotating shaft, and a first gear and a second gear are fixedly sleeved on the rotating shaft. A fixed support plate is fixed on the inner wall of the air-conditioning casing, and a T-shaped slide plate is vertically slid inside the fixed support plate, and a vertical second gear plate is fixed on the T-shaped slide plate. The diameter of the first gear is 3 times the diameter of the second gear, the first gear is meshed with the second gear plate, and the second gear is meshed with the first gear plate, and an extrusion column is vertically fixed on the second gear plate.

[0015] As a preferred technical solution of the present invention, the driving assembly also includes a curved pipe fixed inside the air-conditioning casing, the curved pipe smoothly transitions from a vertical section and an inclined section, the inclined section is penetrated by a through plate, a follower column parallel to the inclined section is fixed on the through plate, the follower column passes through the inclined section and is fixed with a downward pressure column at one end, the extrusion column is inserted into the vertical section at one end away from the second tooth plate, the interior of the curved pipe and between the extrusion 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 guide column passes through the through plate at one end away from the support, and a return spring is sleeved on the outside of the guide column and between the through plate and the support.

[0016] As a preferred technical solution 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, and when the first air guide plate is subjected to downward pressure, the first air guide plate tilts and opens.

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

[0018] As a preferred technical solution of the present invention, an air inlet is provided on the top of the air-conditioning housing, and air outlets are provided on the bottoms of the four side surfaces of the air-conditioning housing.

[0019] As a preferred technical solution of the present invention, it also includes a suction fan, which is fixed at the air inlet on the air conditioner casing and guides air vertically downward. A funnel-shaped air guide tube for gathering wind is fixed at the bottom of the suction fan.

[0020] As a preferred technical solution of the present invention, it also includes a surface cooler, which is fixed just below the funnel-shaped air guide tube and is used for heat exchange.

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

[0022] 1. The present invention, through the arrangement of the driving assembly, can make the second tooth plate move upward by three times the distance the bottom plate moves downward while the bottom plate presses the first air guide plate downward to open the trapezoidal vents, thereby greatly increasing the stroke of the downward pressing column, so that the inclination angle of the second air guide plate pressed by the lower pressure column is greater than the inclination angle of the first air guide plate pressed by the bottom plate, so that the extension line of the second air guide plate after tilting passes through the inclined surface of the tilted first air guide plate, thereby forming the following Figure 11 The air guide direction shown can enable the air after heat exchange to be smoothly discharged from the corresponding air outlet through the double air guide of the second air guide plate and the first air guide plate, thereby achieving a better exhaust effect.

[0023] 2. In the present invention, when the second air guide plate is not squeezed, the lower pressure column and the second air guide plate are located on both sides of the vertical dotted line. When one of the lower pressure columns squeezes the second air guide plate, the other three lower pressure columns will not be affected by the rotation of the second air guide plate. In addition, the extended dotted line of the downward extrusion direction of the lower pressure column passes through the upper surface of the second air guide plate. When the lower pressure column is squeezed, it can be squeezed obliquely downward on the second air guide plate, thereby achieving the squeezing of the second air guide plate. The present invention provides four air guide channels. When one of the air guide channels is guiding air, the other three will not affect it, thereby avoiding the air guide being affected.

[0024] 3. When the lower pressure column of the present invention squeezes the upper surface of the second air guide plate, it makes line-surface contact with the upper surface of the second air guide plate, rather than point-surface contact. The line-surface contact extrusion can ensure the smoothness of the second air guide plate's downward tilt, and avoids the problem of the second air guide plate shaking left and right during the process of the lower pressure column squeezing the second air guide plate. If the second air guide plate shakes left and right, it will affect the wind guidance, making it difficult for the wind to be discharged smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

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

Its installation position is aligned with the lower port of the funnel-shaped air duct, and the distance between the two is maintained at 50-80mm, which not only avoids airflow short circuit, but also ensures that the airflow coverage rate passing through the surface cooler reaches more than 95%.

[0042] A first air guide assembly 4, comprising a bearing plate 41, the bearing plate 41 being horizontally fixed to the interior of the air conditioner housing 1 and being located directly below the surface cooler 3. The bearing plate 41 is provided with four trapezoidal ventilation holes. The bottom of the bearing plate 41 is rotatably connected to four first air guide plates 42 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 fixed at its bottom end to the center of the supporting plate 41, a supporting seat 52 fixed to the top of the column 51, a rotating ball 53 rotating inside the supporting seat 52, and a second air guide plate 55 fixedly connected to the rotating ball 53 via a connecting block 54. Four supporting rotating rods 56 supporting the second air guide plate 55 are rotatably connected to the circumference of the column 51 via a coil spring. When the second air guide plate 55 is not squeezed, the second air guide plate 55 is in a horizontal state due to the support of the four supporting rotating rods 56;

[0044] 6 and 7. The four drive assemblies 6 are respectively located on the four inner side walls of the air-conditioning casing 1, and the drive assembly 6 is used to drive the first air guide plate 42 and the second air guide plate 55 to tilt simultaneously, until the extension line after the second air guide plate 55 is tilted passes through the inclined surface of the tilted first air guide plate 42. The four drive assemblies 6 are respectively located on the four inner side walls of the air-conditioning casing 1. The drive assembly 6 includes an electric telescopic rod 61, and the electric telescopic rod 61 is fixed in the air-conditioning casing 1. The telescopic end of the electric telescopic rod 61 is fixed with a bottom plate 62, and a first gear plate 63 is vertically fixed on the bottom plate 62. The internal rotation of the air-conditioning casing 1 is connected with a rotating shaft, and a first gear 64 and a second gear 65 are fixedly sleeved on the rotating shaft. A fixed support plate 66 is fixed on the inner wall of the air-conditioning casing 1, and a T-shaped slide plate 67 is vertically slid inside the fixed support plate 66. A vertical second gear plate 68 is fixed on the T-shaped slide plate 67. The diameter of the first gear 64 is 3 times the diameter of the second gear 65. The second tooth plate 68 is meshed and connected, and the second gear 65 is meshed and connected with the first tooth plate 63. An extrusion column 69 is vertically fixed on the second tooth plate 68. The drive assembly 6 also includes a bent pipe 70 fixed inside the air-conditioning casing 1. The bent pipe 70 has a smooth transition from a vertical section and an inclined section. The inclined section slides through a through plate 71, and a follower column 72 parallel to the inclined section is fixed on the through plate 71. The follower column 72 passes through one end of the inclined section and is fixed with a downward pressure column 73. The end of the extrusion column 69 away from the second tooth plate 68 is inserted into the vertical section. The interior of the bent pipe 70 and between the extrusion column 69 and the through plate 71 are filled with lightweight balls 74. The end of the inclined section is fixed with a support 75. 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 located 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, the outside air enters from the air inlet 11, is gathered by the funnel-shaped air guide tube, and then blows vertically downward to the surface cooler 3. After heat exchange, it forms cold air and continues downward to enter the space between the first air guide component 4 and the second air guide component 5.

[0048] Wind control stage

[0049] When air needs to be supplied from the air outlet 12 on one side, the drive assembly 6 on the corresponding side is started:

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

[0051] At the same time, the first tooth plate 63 moves downward with the bottom plate, and drives the second tooth plate 68 to move upward by 60-90 mm through gear transmission, squeezing the lightweight ball 74 in the bent pipe 70, pushing the down-pressure column 73 to move downward by 40-50 mm in the 45° direction, squeezing the second air guide plate 55 to tilt by 30°-40°.

[0052] Since the inclination angle of the second air guide plate is greater than that of the first air guide plate, its extension line precisely aligns with the inclined surface 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 inclined surface of the first air guide plate to the corresponding air outlet 12, thereby improving the air supply efficiency.

[0053] Reset phase

[0054] After the air supply is completed, the electric telescopic rod 61 contracts, the bottom plate 62 and the lower pressure column 73 are withdrawn, and the first air guide plate 42 and the second air guide plate 55 are quickly reset under the action of the spring elastic force, blocking the trapezoidal ventilation holes and returning to a horizontal state to avoid airflow crosstalk between different channels.

[0055] Energy-saving principles and enhanced advantages

[0056] Energy saving by variable air channel

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

[0058] Structural optimization and energy saving

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

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

[0061] Sealed design for energy saving

[0062] The unopened channel is tightly sealed by the first air guide plate to prevent cold air from escaping from non-target areas, further reducing cooling loss.

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

[0064] When it is necessary to use an energy-saving variable wind multi-channel air-conditioning unit of the present invention, first, the electric telescopic rod 61 at the corresponding position is started according to the air duct where the air is to be discharged. The telescopic end of the electric telescopic rod 61 drives the bottom plate 62 to move downward, and the bottom plate 62 moves downward to squeeze the first air guide plate 42 to tilt downward. At this time, the trapezoidal vent is opened, and the bottom plate 62 moves downward while driving the first gear plate 63 to move downward. Since the first gear plate 63 is meshed with the second gear 65, the first gear 64 is meshed with the second gear plate 68, the first gear 64 and the second gear 65 rotate coaxially, and the diameter of the first gear 64 is 3 times the diameter of the second gear 65, so when the first gear plate 63 moves downward, the second gear plate 6 8 moves upward for 3 times the distance the first tooth plate 63 moves downward, the second tooth plate 68 drives the extrusion column 69 to move upward, the extrusion column 69 squeezes the lightweight ball 74, so that the through plate 71, the follower column 72 and the lower pressure column 73 move obliquely downward along the length direction of the inclined section, when the lower pressure column 73 moves obliquely downward along the length direction of the inclined section, the lower pressure column 73 squeezes the second air guide plate 55 to tilt, because the distance the second tooth plate 68 moves upward is 3 times the distance the first tooth plate 63 moves downward, the inclination angle of the second air guide plate 55 is greater than the inclination angle of the first air guide plate 42, so that the extension line of the second air guide plate 55 after tilting passes through the inclined surface of the tilted first air guide plate 42, thereby forming the following Figure 11 The wind direction shown in the present invention Figure 4 It can be seen from the figure that when the second air guide plate 55 is not squeezed, the lower pressure column 73 and the second air guide plate 55 are located on both sides of the vertical dotted line, that is, when one of the lower pressure columns 73 squeezes the second air guide plate 55, the other three lower pressure columns 73 will not be affected by the rotation of the second air guide plate 55. Figure 4 As can be seen, the extended dotted line of the oblique downward extrusion direction of the lower pressure column 73 passes through the upper surface of the second air guide plate 55. That is, when the lower pressure column 73 is squeezed, it can be squeezed obliquely downward on the second air guide plate 55, thereby squeezing the second air guide plate 55.

[0065] The present invention is provided with the driving assembly 6, so that the bottom plate 62 can press the first air guide plate 42 downward to open the trapezoidal ventilation hole, while the second tooth plate 68 moves upward by 3 times the distance the bottom plate 62 moves downward, thereby greatly increasing the stroke of the downward pressing column 73 to press the second air guide plate 55 obliquely downward, so that the inclination angle of the second air guide plate 55 squeezed by the lower pressing column 73 is greater than the inclination angle of the first air guide plate 42 squeezed by the bottom plate 62, so that the extension line of the second air guide plate 55 after tilting passes through the inclined surface of the tilted first air guide plate 42, thereby forming Figure 11The wind guide direction shown in the figure, through the two wind guides of the second wind guide plate 55 and the first wind guide plate 42, can make the wind after heat exchange be discharged smoothly from the corresponding air outlet 12, thereby achieving better exhaust effect. In the present invention, when the second wind guide plate 55 is not squeezed, the lower pressure column 73 and the second wind guide plate 55 are located on both sides of the vertical dotted line. When one of the lower pressure columns 73 squeezes the second wind guide plate 55, the other three lower pressure columns 73 will not be affected by the rotation of the second wind guide plate 55. In addition, the extended dotted line of the downward squeezing direction of the lower pressure column 73 passes through the upper surface of the second wind guide plate 55. When the lower pressure column 73 is squeezed, it can be squeezed obliquely downward on the second wind guide plate 55, thereby achieving squeezing of the second wind guide plate 55. The present invention is provided with four wind guide channels. When one of the wind guide channels is guiding the wind, the other three will not affect it, thereby avoiding the wind guide being affected. When the lower pressure column 73 of the present invention squeezes the upper surface of the second air guide plate 55, it has line-surface contact with the upper surface of the second air guide plate 55, rather than point-surface contact. The line-surface contact extrusion can ensure the smoothness of the second air guide plate 55 tilting downward, avoiding the problem of the second air guide plate 55 shaking left and right during the process of the lower pressure column 73 squeezing the second air guide plate 55. If the second air guide plate 55 shakes left and right, it will affect the wind guidance, making it difficult for the wind to be discharged smoothly.
