Description

Technical Field

[0001] This utility model belongs to the field of central air conditioning ventilation duct technology, specifically an energy-saving central air conditioning ventilation duct air distribution device. Background Technology

[0002] Air conditioning is arguably one of the most influential inventions, providing the previously unimaginable comfort of warmth in winter and coolness in summer. Air conditioners come in various types, including wall-mounted, floor-standing, and central air conditioning systems. A central air conditioning system consists of one or more cold / heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners (such as stand-alone units or VRV systems), this system centrally processes air to achieve comfort requirements. It utilizes the principle of liquid vaporization refrigeration to provide the necessary cooling capacity to offset the heat load of the indoor environment; the heating system provides the necessary heat to offset the heating / cooling load of the indoor environment.

[0003] Meanwhile, application number CN220471829U, entitled "An Energy-Saving Central Air Conditioning Ventilation Duct Airflow Distribution Device," describes an energy-saving central air conditioning ventilation duct airflow distribution device comprising a ventilation duct and a central air conditioning unit. The central air conditioning unit is connected to an indoor unit via the ventilation duct. An indoor air outlet casing is bolted to the right side of the indoor unit. Human proximity sensors are bolted to the four corners of the indoor air outlet casing. A temperature display panel is located to the right of the human proximity sensors, and an air outlet is located below the temperature display panel. Speakers are located on both sides of the air outlet, and a monitoring camera is located in the center below the speakers. The monitoring camera is connected to a wind power control mainboard via a wiring harness. A microprocessor is connected to the surface of the wind power control mainboard via a wiring harness. The microprocessor is connected to an inverter circuit and an operating parameter detection circuit via wiring harnesses. This energy-saving central air conditioning ventilation duct airflow distribution device disclosed in this utility model has the advantages of reducing energy consumption, remotely monitoring indoor environmental conditions, and high safety.

[0004] The aforementioned technical solution suffers from the problem of airflow direction failing to follow the movement of people during use. In real-world applications, the area where people are active changes dynamically, making it impossible to dynamically adjust the airflow based on the real-time location of the crowd. It's difficult to achieve the optimal angle between the airflow and the crowd's movement direction. When the airflow direction significantly overlaps with the direction of crowd movement, the airflow cannot effectively cover the crowd, negatively impacting the user experience of the central air conditioning system.

[0005] Therefore, an energy-saving central air conditioning ventilation duct air distribution device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an energy-saving central air conditioning ventilation duct air distribution device that enables the airflow direction to automatically follow the direction of people's activities, avoiding significant overlap between the airflow direction and the people, and further improving the user experience of central air conditioning.

Gears are installed on the surface of the movable rod. A rack plate is slidably connected in the slot opened on the upper surface of the ventilation duct. The rack plate meshes with multiple gears. Detectors are symmetrically installed on the surface of the ventilation duct. A drive stabilization assembly is installed on the surface of the ventilation duct.

[0009] Preferably, the detector is electrically connected to the main control board inside the central air conditioning unit.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides an energy-saving central air conditioning ventilation duct air distribution device, including a central air conditioning body 1, a ventilation duct 12 installed on one side surface of the central air conditioning body 1, and a flow guiding and following component 2 installed on the surface of the ventilation duct 12.

[0024] The airflow guiding and following component 2 includes airflow guide plates 21. Multiple airflow guide plates 21 are rotatably connected to the air outlet of the ventilation duct 12. A movable rod 22 is installed at the top of the airflow guide plate 21. One end of the movable rod 22 passes through the air outlet of the ventilation duct 12 and is rotatably connected in a slot opened on the upper surface of the ventilation duct 12. Gears 23 are installed on the surface of the movable rod 22. A rack plate 24 is slidably connected in the slot opened on the upper surface of the ventilation duct 12. The rack plate 24 meshes with multiple gears 23. Detectors 25 are symmetrically installed on the surface of the ventilation duct 12. A drive stabilizing component 3 is installed on the surface of the ventilation duct 12, which enables the airflow direction to automatically follow the direction of people's movement, avoiding a large overlap between the airflow direction and the people, and further improving the user experience of the central air conditioning.

[0025] Specifically, the detector 25 is electrically connected to the main control board inside the central air conditioning unit 1, thereby enabling automatic control and facilitating the use of the central air conditioning.

[0026] Furthermore, multiple deflector plates 21 are evenly distributed at the air outlet of the ventilation duct 12, thereby enabling uniform airflow.

[0027] like Figures 1 to 4 As shown, the drive stabilization component 3 includes a connecting plate 31. The connecting plate 31 is installed on the bottom surface of the rack plate 24. The ventilation duct 12 has a groove adapted to the connecting plate 31 inside. The connecting plate 31 is slidably connected in this groove. A hydraulic rod 32 is installed inside the ventilation duct 12. The telescopic end of the hydraulic rod 32 is connected to the connecting plate 31, so that the guide plate 21 can be automatically driven to adjust its angle to follow the crowd. The driving process is relatively stable, which further improves the stability of the central air conditioning system.

[0028] It is worth noting that the hydraulic rod 32 is electrically connected to the main control board inside the central air conditioning unit 1, thereby enabling the automatic drive of the hydraulic rod 32 to extend and retract.

[0029] like Figures 1 to 4 As shown, a limiting rod 33 is slidably connected in the through hole opened on the surface of the connecting plate 31. Both ends of the limiting rod 33 penetrate the connecting plate 31 and are installed in the slot opened on the upper surface of the ventilation duct 12, thereby limiting the position of the connecting plate 31 and improving the stability of the connecting plate 31 when it moves.

[0030] The structure of the central air conditioning unit 1, ventilation duct 12, detector 25 and main control motherboard is existing technology and is the same as the published patent, application number CN220471829U, "An energy-saving central air conditioning ventilation duct wind power distribution device". For specific operation, please refer to the published patent.

[0031] Working principle and process: The detector 25 installed on the surface of the ventilation duct 12 monitors the location and distribution of people in the room in real time. The detector 25 is the same type as the camera in the prior art. For details, please refer to the published patent.

[0032] The detector 25 converts the collected crowd location data into electrical signals and transmits them to the main control board inside the central air conditioning unit 1;

[0033] After receiving the crowd location data, the main control board performs real-time analysis to calculate the crowd's concentration area, activity direction, and relative positional relationship with the air outlet of ventilation duct 12.

[0034] Based on the location and distribution of the crowd, the main control board calculates the optimal angle that the deflector 21 needs to be adjusted to ensure that the wind direction can cover the crowd activity area to the greatest extent.

[0035] The main control board sends a control signal to the hydraulic rod 32, and the telescopic end of the hydraulic rod 32 begins to move, pushing or pulling the connecting plate 31 to slide in the groove inside the ventilation duct 12. The sliding of the connecting plate 31 causes the rack plate 24 connected to it to slide synchronously in the empty groove on the upper surface of the ventilation duct 12. The sliding of the rack plate 24 drives multiple gears 23 to rotate synchronously through meshing. The rotation of the gears 23 drives the movable rod 22 connected to it to rotate, thereby causing the guide plate 21 to rotate around its rotation axis to the calculated optimal angle.

[0036] During the sliding process of the connecting plate 31, the limiting rod 33 guides and limits it to ensure that the connecting plate 31 slides smoothly, thereby ensuring the motion stability of the rack plate 24 and the guide plate 21.

[0037] The detector 25 continuously monitors changes in the position of the crowd. The main control board dynamically adjusts the angle of the guide plate 21 based on the latest data, and drives the output end of the hydraulic rod 32 to extend and retract, so as to achieve real-time tracking of the wind direction.

[0038] By adjusting the angle of the deflector plate 21, the air delivered by the central air conditioning unit 1 can be precisely directed to the area where people are active, improving air circulation efficiency and human comfort. Since the air direction can follow the people, it avoids the ineffective air delivery of traditional equipment in uninhabited or sparsely populated areas, thereby significantly reducing energy consumption and achieving the goal of energy saving.
