Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and specifically relates to a dual-function air conditioning fire exhaust device. Background Technology

[0002] Air conditioning refers to equipment that uses artificial means to partially or completely regulate the temperature, humidity, airflow and cleanliness of air in a closed space, so that the air parameters of the target environment meet the requirements. It generally includes cold and heat source equipment, cold and heat medium system, terminal devices and other auxiliary equipment, mainly including water pumps, fans and pipeline systems.

[0003] In existing technologies, air conditioning and smoke exhaust systems in production workshops each have their own ductwork. This results in air conditioning ducts and fire smoke exhaust ducts occupying a large area when installed in the production workshop, and requires separate planning for the air conditioning ducts and smoke exhaust ducts to avoid conflicts between them, leading to excessive costs. To address this issue, how to design a dual-function air conditioning, fire protection, and smoke exhaust device has become a problem that we need to solve. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a dual-function device for air conditioning, fire protection and smoke exhaust.

[0005] To achieve the above objectives, this utility model provides a dual-function air conditioning fire smoke extraction device, comprising an air conditioning unit, wherein an air blowing window, a return air window, and an air inlet window are rotatably connected inside the air conditioning unit, the air blowing window, the return air window, and the air inlet window are respectively connected inside the air blowing port, the return port, and the air inlet of the air conditioning unit, a pipe is fixedly connected to one side of the air conditioning unit, the pipe is located on one side of the air inlet window, and a backup power supply is fixedly installed inside the air conditioning unit; and a suction assembly, which is used to assist the air conditioning unit in suctioning the smoke generated inside the production workshop, and the suction assembly is connected to the air conditioning unit.

[0006] In the above technical solution, a limiting component is further fixedly installed inside the air conditioner body, and a fan is fixedly installed inside the limiting component. The fan is located inside the air conditioner body, and a gear and a friction ring are fixedly connected to the outer wall of the output shaft of the fan.

[0007] In the above technical solution, a connecting rod is further provided on one side of the gear and friction ring, a rack is fixedly connected to the side of the connecting rod near the gear, and a T-shaped limiting rod is inserted into the inside of the connecting rod.

[0008] In the above technical solution, a fixing block is fixedly connected to one end of the T-shaped limiting rod. The fixing block is fixedly connected to the outer wall of the limiting member. A spring is provided between the fixing block and the connecting rod. The spring is sleeved on the outer wall of the T-shaped limiting rod.

[0009] In the above technical solution, a connecting rope is fixedly connected to the top of the connecting rod, a rotating rod is provided on the outer wall of the connecting rope, the rotating rod is rotatably connected to the inside of the air conditioner body, and a square frame is fixedly connected to the end of the connecting rope away from the connecting rod, the square frame is slidably connected to the inside of the air conditioner body.

[0010] In the above technical solution, further, a plurality of square plates are hinged to one side of the frame. The plurality of square plates are hinged to one side of the frame in a ring with the fan output shaft as the center. A connecting plate is inserted into the interior of every two adjacent square plates. The connecting plate is rotatably connected to the interior of the frame. An elastic sheet is slidably connected to the interior of the square plate. The elastic sheet is disposed between two connecting plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting up a suction component, when the air conditioner is in smoke exhaust mode, the square plate and connecting plate unfold to form a tapering horn. The smoke drawn into the air conditioner body by the reverse-rotating fan gradually narrows as it passes through the tapering horn, increasing the flow rate of the smoke and improving the suction efficiency of the smoke, thus preventing the mist from escaping into the production workshop. By setting the entire pipeline at an upward angle, the air conditioner unit discharges the extracted smoke into the pipeline. The smoke generated by the fire is hotter than the normal outside air, causing the smoke to expand due to thermal expansion and create buoyancy, which is then discharged from the upward-sloping pipeline. The buoyancy of the smoke, combined with the blowing action of the air conditioner unit, can increase the speed of smoke discharge, thereby increasing the speed of smoke discharge from the production workshop.

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 2 The illustrated air conditioning fire smoke exhaust dual-function device includes an air conditioning body 1. An air blowing window 2, a return air window 3, and an air inlet window 4 are rotatably connected inside the air conditioning body 1. These windows are respectively connected to the air outlet, return air inlet, and air inlet of the air conditioning body 1. A pipe 5 is fixedly connected to one side of the air conditioning body 1. The pipe 5 is angled upwards, allowing the air conditioning body 1 to exhaust extracted smoke into it. The smoke generated by the fire is hotter than the surrounding air, causing it to expand due to thermal expansion and create buoyancy, thus being discharged from the angled pipe 5. The buoyancy of the smoke... In conjunction with the blowing action of the air conditioning unit 1, the speed of smoke extraction can be increased, thereby improving the extraction speed of smoke from inside the production workshop. The duct 5 is located on one side of the air inlet window 4. A backup power supply 21 is fixedly installed inside the air conditioning unit 1. By setting up the backup power supply 21, power can be supplied to the air conditioning in the event of a fire, enabling the air conditioning to extract the smoke generated by the fire from inside the production workshop, thus preventing damage to the power supply line of the air conditioning and causing the air conditioning to stop working. The suction component is used to assist the air conditioning unit 1 in extracting the smoke generated inside the production workshop, and the suction component is connected to the air conditioning unit 1.

[0016] like Figures 2 to 7As shown, a limiting component 6 is fixedly installed inside the air conditioner body 1. A fan 7 is fixedly installed inside the limiting component 6. The fan 7 is located inside the air conditioner body 1. A gear 8 and a friction ring 9 are fixedly connected to the outer wall of the output shaft of the fan 7. A connecting rod 10 is provided on one side of the gear 8 and the friction ring 9. A rack 11 is fixedly connected to the side of the connecting rod 10 near the gear 8. A T-shaped limiting rod 12 is inserted into the connecting rod 10. The T-shaped limiting rod 12 limits the connecting rod 10, preventing the connecting rod 10 from rotating and affecting the suction assembly. For the normal operation of the component, a fixing block 13 is fixedly connected to one end of the T-shaped limiting rod 12. The fixing block 13 is fixedly connected to the outer wall of the limiting component 6. A spring 14 is provided between the fixing block 13 and the connecting rod 10. The spring 14 can apply pressure to the rack 11, so that a certain frictional force is generated between the connecting rod 10 and the friction ring 9. As the friction ring 9 rotates and drives the connecting rod 10 to descend, the friction ring 9 moves downward through friction and the weight of the connecting rod 10 itself. The spring 14 is sleeved on the outer wall of the T-shaped limiting rod 12. A connecting rope 15 is fixedly connected to the top of the connecting rod 10. The length of the connecting rope 15 is designed with a margin to prevent the connecting rod 10 from pulling the square frame 17 during its initial descent driven by the friction ring 9. Only after the gear 8 and rack 11 mesh will the rotating rod 16 straighten and pull the square frame 17, preventing jamming. The rotating rod 16 is mounted on the outer wall of the connecting rope 15 and is rotatably connected to the inside of the air conditioner body 1. The end of the connecting rope 15 away from the connecting rod 10 is fixedly connected to the square frame 17, which is slidably connected to the inside of the air conditioner body 1. Multiple square plates 18 are hinged to one side of the fan 7. The multiple square plates 18 are hinged in a ring at equal intervals to one side of the frame 17 with the output shaft of the fan 7 as the center. A connecting plate 19 is inserted into the interior of every two adjacent square plates 18. The connecting plate 19 is rotatably connected to the interior of the frame 17. Since the connection part between the connecting plate 19 and the frame 17 is circular, the connecting plate 19 can rotate freely to a certain extent with the rotatable connection part of the frame 17 as the center. An elastic piece 20 is slidably connected inside the square plate 18 and is disposed between two connecting plates 19.

[0017] Working principle: When a fire occurs in the production workshop, the smoke alarm inside the workshop will be triggered, causing the smoke alarm to transmit a signal to the air conditioning unit 1. This will cause the air conditioning unit 1 to switch from air conditioning mode to smoke exhaust mode. The air conditioning unit 1 will then switch the forward operation control signal of the fan 7 to reverse operation mode, allowing the air conditioning unit 1 to control the air blowing window 2 and the air intake window 4 to open to the maximum ventilation angle and control the return air window 3 to close. At this time, the air conditioning unit 1 switches to smoke exhaust mode, forming a "one-way suction-upward exhaust" airflow channel with the duct 5. This can exhaust the smoke inside the production workshop and effectively prevent smoke backflow. The smoke exhaust mode can be activated in the early stage of a fire, buying golden time for rescue operations and minimizing the risk of casualties and property losses. Furthermore, when the air conditioner body 1 is in the smoke exhaust state, the fan 7 rotates in the reverse direction, causing the gear 8 and friction ring 9 on the output shaft of the fan 7 to rotate in the opposite direction. This causes the friction ring 9 to drive the connecting rod 10 to descend until the rack 11 on the connecting rod 10 meshes with the gear 8. At this time, the gear 8 drives the connecting rod 10 to continue descending through the rack 11, causing the connecting rod 10 to pull the connecting rope 15. After the connecting rope 15 changes the direction of tension through the rotating rod 16, it can pull the square frame 17 to move along the air conditioner body 1 towards the rotating rod 16, allowing the square frame 17 to drive the square plate 18 and connecting plate 19 to disengage from the interior of the air conditioner body 1. When the rack 11 descends to the point where it no longer meshes with the gear 8, the rack 11 drives the connecting rod 10 to touch the bottom of the inner wall of the air conditioner body 1. The connecting rod 10, through the connecting rope 15, pulls the square frame 17 to abut against the rotating rod 16. At this time, the square plate 18 and connecting plate 19 disengage from the interior of the air conditioner body 1. Plate 19 is completely detached from the interior of the air conditioner body 1, allowing the elastic sheet 20 inside the square plate 18 to extend and push the connecting plate 19. This allows the square plate 18 to unfold in conjunction with the connecting plate 19, forming a tapered flared opening. As the smoke drawn into the air conditioner body 1 by the reverse-rotating fan 7 passes through the tapered flared opening, the cross-section gradually narrows, increasing the flow rate of the smoke and improving the suction efficiency. This prevents the mist from escaping into the production workshop. It should be noted that when the fire inside the production workshop is extinguished and the air conditioner stops working, and when the staff is inspecting the air conditioner, the square plate 18 and the connecting plate 19 can be pressed back into the interior of the air conditioner body 1. This allows the connecting plate 19 to press the elastic sheet 20 again, causing the square plate 18 and the connecting plate 19 to push the square frame 17 back to its original position. The square frame 17 then pulls the connecting rod 10 upwards and back to its original position via the connecting rope 15.
