Description

Technical Field

[0001] The invention relates to the technical field of air conditioning equipment, and in particular to a special panel capable of adjusting air intake volume. Background Art

[0002] Ventilation design is widely used in many fields such as architecture and industry. Its purpose is to improve the quality of indoor environment, ensure the health of personnel and the normal operation of equipment. Early humans used natural wind for ventilation by setting simple openings in living places, such as doors, windows, vents, etc. With the development of construction technology, some more complex natural ventilation designs have emerged. After the Industrial Revolution, the scale of industrial production continued to expand, and environmental problems in factories became increasingly prominent. It was difficult to meet the needs by natural ventilation alone. Therefore, mechanical ventilation technology came into being. Through forced air exchange through equipment such as fans, ventilation volume and ventilation effect can be more effectively controlled. With the continuous improvement of people's requirements for indoor environmental quality and the popularization of environmental protection and energy-saving concepts, modern ventilation technology is developing in the direction of intelligence, energy saving and personalization. This will cause the following problems in actual operation:

[0003] 1. Air conditioners and cooling towers are usually in outdoor environments, and larger particles of impurities such as dust, pollen, and catkins in the air are easily inhaled into the equipment. These impurities will adhere to the surface of the heat exchanger as the air flows, forming a layer of dirt. Over a long period of time, the dirt will become thicker and thicker, which not only hinders the transfer of heat, but also blocks the channels of the heat exchanger, causing poor air circulation and reducing the effective utilization of the heat exchange area. At the same time, in the design process of air conditioners and cooling tower equipment, if the air flow organization is not reasonably considered, the air may be unevenly distributed on the surface of the heat exchanger. For example, the air flow rate in some areas is too fast, while the air flow rate in some areas is too slow, which will prevent the heat exchange area of ​​the heat exchanger from being fully utilized. In areas where the flow rate is too fast, the contact time between the air and the heat exchanger is too short, and the heat cannot be fully absorbed or released; in areas where the flow rate is too slow, airflow dead zones are easily formed, resulting in heat accumulation and affecting the overall heat exchange effect. The direct contact between conventional sheet metal and the vibrating body can also cause vibration noise;

[0004] 2. Common ventilation conditions in indoor environments include removing kitchen fumes, bathroom odors, harmful gases left after decoration, powder waste gas and waste heat generated during the production process, etc. These discharged substances often affect the surrounding environment and pedestrians. If they are blown directly to the outside without protection, they will affect the surrounding environment in a large area and even threaten the safety of pedestrians. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present invention after paying a lot of creative work.

[0006] Specifically, the technical problem to be solved by the present invention is: to provide a special panel with adjustable air intake volume to solve the current problem that when the indoor environment is ventilated with the outside world, the fan blows directly outward without protection, which has a wide impact range. Mechanical equipment such as air-conditioning equipment and cooling tower equipment use heat exchangers through heat exchangers, and the heat exchangers are easily dirty and blocked, and the heat exchange area is not efficiently used, which affects the heat exchange effect. The direct contact between the sheet metal and the vibrating body will also cause vibration noise.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A special panel capable of adjusting the air intake volume comprises an outer frame, a gear rotating folding mechanism is fixedly installed on the inner surface of the outer frame, a shock absorbing and noise reducing mechanism is installed on the outer surface of the outer frame, and a filter is fixedly installed on the back of the outer frame;

[0009] The gear rotating folding mechanism includes a No. 1 connecting rod, the outer surface of which is rotatably connected to the inner surface of the outer frame, a No. 1 folding sheet metal is fixedly installed on the outer surface of the No. 1 connecting rod, and both ends of the No. 1 connecting rod penetrate the outer frame and extend to the outside of the outer frame.

[0010] As an improved technical solution, the gear rotary folding mechanism also includes a gear, the inner surface of the gear is fixedly connected to the outer surface of the No. 1 connecting rod, and the outer surface of the gear is transmission-connected to a transmission toothed chain.

[0011] As an improved technical solution, the shock-absorbing and noise-reducing mechanism includes a convex bulge, the front side of the convex bulge is fixedly connected to the back side of the outer frame, a rubber shock-absorbing pad is fixedly installed on the back side of the convex bulge, and a shock-absorbing spring is fixedly installed on the inner surface of the rubber shock-absorbing pad.

[0012] A special panel, the adjustable air intake volume, includes a knob rotating folding mechanism including a No. 2 connecting rod, the outer surface of the No. 2 connecting rod is rotatably connected to the inner surface of the outer frame, both ends of the No. 2 connecting rod pass through the outer frame and extend to the outside of the outer frame, and the outer surface of the No. 2 connecting rod is fixedly installed with a No. 2 folding sheet metal.

[0013] As an improved technical solution, the knob rotating folding mechanism further includes a knob plate, and opposite ends of the two knob plates are fixedly connected to the two ends of the second connecting rod.

[0014] After adopting the above technical solution, the beneficial effects of the present invention are:

[0015] 1. Through the design of adjustable panel air intake, by using the first connecting rod, the first hinge sheet metal, the gear and the transmission chain, the synchronous angle adjustment of multiple first hinge sheet metals is achieved. By using the second connecting rod, the second hinge sheet metal and the rotating plate, the manual knob can be used to finely adjust the air intake of each path, realizing the control of the air intake size and angle at different upper and lower positions. Then, through the cooperation of the filter screen and the outer frame, large particle impurities such as dust and catkins are blocked, so as to adjust the air outlet angle and direct the generated dust, hot air, etc. to the direction with less impact on the surrounding environment and pedestrians. At the same time, the design of the filter screen can effectively prevent the sundries generated in factory production and kitchens from flying out and posing a threat to the surrounding pedestrians.

[0016] 2. Through the cooperation of the outer frame and the filter screen, the impact of external sundries entering on the heat exchanger can be effectively reduced. Through the cooperation of the outer frame and the convex hull, a certain distance is maintained between the panel and the heat exchanger. Through the design of the manual knob, the air intake of each path is finely adjusted, realizing the control of the air intake size and angle at different upper and lower positions, and efficiently utilizing the heat exchange area at different heights of the heat exchanger. In the area where the flow rate is too fast, the contact time between the air and the heat exchanger is too short to fully absorb or release heat, and the adjustable panel hinge can reduce the air intake; in the area where the flow rate is too slow, an air flow dead zone is easily formed, resulting in heat accumulation, and the adjustable panel hinge sheet metal can increase the air intake. In addition, the vibration of the fan will cause the sheet metal connected to the fan to vibrate synchronously, generating noise, and the design of the convex hull, rubber shock pads and shock springs can also effectively reduce the generation of noise.

[0032] Embodiment 1

[0033] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Collectively shown, this embodiment provides a special panel with adjustable air intake. This special panel with adjustable air intake includes an outer frame 1. A gear rotating hinge mechanism 2 is fixedly installed on the inner surface of the outer frame 1. A shock absorption and noise reduction mechanism 3 is installed on the outer surface of the outer frame 1. A filter screen 4 is fixedly installed on the back surface of the outer frame 1.

[0034] The gear rotating hinge mechanism 2 includes a first connecting rod 21. The outer surface of the first connecting rod 21 is rotatably connected to the inner surface of the outer frame 1. A first hinge sheet metal 22 is fixedly installed on the outer surface of the first connecting rod 21. Both ends of the first connecting rod 21 penetrate through the outer frame 1 and extend to the outside of the outer frame 1.

[0035] The outer frame 1 is formed by bending and welding sheet metal parts. The hinge sheet metal is separately processed and then installed together with the outer frame 1.

[0036] As Figure 1 、 Figure 2 and Figure 3 Collectively shown, the gear rotating hinge mechanism 2 further includes a gear 23. The inner surface of the gear 23 is fixedly connected to the outer surface of the first connecting rod 21. A transmission chain 24 is drivingly connected to the outer surface of the gear 23.

[0037] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Collectively shown, the shock absorption and noise reduction mechanism 3 includes a convex bump 31. The front surface of the convex bump 31 is fixedly connected to the back surface of the outer frame 1. A rubber shock pad 32 is fixedly installed on the back surface of the convex bump 31. A shock absorption spring 33 is fixedly installed on the inner surface of the rubber shock pad 32.

[0038] A round hole is opened in the middle of the convex bump 31 for fixing bolts with the mechanical body.

[0039] In this embodiment, the first folding sheet metal 22 can rotate through the gear 23 and the transmission chain 24, enabling multiple first folding sheet metals 22 to rotate synchronously at an angle. During the rotation of the first folding sheet metal 22, the angle of air inlet and outlet and the air intake volume can be changed, reducing the number of adjustments, and it is suitable for usage scenarios where precise air volume control is not required. The small convex bumps 31 at the four corners are used for the installation and fixation of the panel. The protruding part can separate the panel from other installation parts, reducing the contact area. At the same time, the rubber damping pads 32 pasted on the back can change the rigid connection between the panel and the installation parts. These two designs can effectively reduce the contact between the vibrating components and the panel, and reduce the noise generated by the contact between the sheet metal and the vibrating components. The design of the filter net 4 can reduce the entry of impurities such as dust and catkins in the air into the interior of the machine, causing blockage of the internal heat exchanger, and at the same time, it can also prevent dust or debris from flying out when the internal environment of the kitchen, factory, etc. discharges air.

The outer surface of the second connecting rod 51 is rotatably connected to the inner surface of the outer frame 1. Both ends of the second connecting rod 51 penetrate through the outer frame 1 and extend to the outside of the outer frame 1. A second folding sheet metal 52 is fixedly installed on the outer surface of the second connecting rod 51.

[0042] As Figure 6 、 Figure 7 and Figure 8 collectively shown, the knob rotary folding mechanism 5 further includes a knob plate 53. One end of each of the two knob plates 53 facing each other is fixedly connected to both ends of the second connecting rod 51.

[0043] In this embodiment, the second folding sheet metal 52 can drive the second connecting rod 51 to rotate through the right manual knob plate 53, and the second connecting rod 51 drives the second folding sheet metal 52 to rotate to achieve angular rotation. During the rotation of the second folding sheet metal 52, the angle of air inlet and outlet and the air intake volume can be changed. Among them, the manual knob can be used to finely adjust the air intake volume of each path, realizing the control of the air intake volume and angle at different upper and lower positions.
