A duct flow guiding device

Abstract

This invention discloses an air duct guiding device, relating to the field of air duct guiding. It includes an air duct with an internal airflow channel and a drainage jacket at its bottom. The drainage jacket is separated from the airflow channel by a guide plate. When airflow passes through the airflow channel, condensation is generated. The condensation drips to the bottom of the airflow channel and then drains into the drainage jacket. In this invention, the condensation flows into the drainage jacket through a drainage channel. The amount of condensation in the airflow channel is small, preventing accumulation and thus reducing energy consumption for long-distance airflow transmission. The condensation can flow directly into the drainage channel from the corresponding inclined opening of the baffle, without continuing to flow along the bottom of the airflow channel and affecting the airflow. This also reduces the problem of poor HVAC performance caused by condensation absorbing heat from the airflow.

Description

Technical Field

[0001] This invention relates to the field of airflow guidance, and particularly to an airflow guidance device. Background Technology

[0002] Building heating and ventilation ducts are typically used to deliver airflow, including hot and cold air, to maintain a comfortable temperature inside the building while delivering heating.

[0003] However, building heating and ventilation ducts are usually laid out in a long manner, resulting in low wind power transmission efficiency.

[0004] Furthermore, when existing building heating and ventilation ducts deliver cold air, if the air temperature around the duct is high, or if the duct itself has a low temperature, water vapor in the air may condense on the outer wall of the duct, forming water droplets. Conversely, when delivering hot air, if the outside temperature is low, condensation may also form on the inner wall. The presence of water droplets on the wall reduces airflow speed.

[0005] Therefore, it is necessary to propose a duct flow guiding device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an air duct guiding device to solve the problem that water droplets adhere to the walls of existing building heating and ventilation ducts when delivering hot air, thus affecting the air velocity.

[0008] The bottom of the wind power channel is provided with a drainage interlayer. The drainage interlayer is isolated from the wind power channel by a guide plate. The guide plate is provided with a drainage groove. When the wind flows through the inside of the wind power channel, condensation water is generated. The condensation water drips to the bottom of the wind power channel and is discharged into the drainage interlayer from the drainage groove.

[0009] Preferably, the drainage channel is arranged at an angle, and one end of the drainage channel that connects to the drainage interlayer is inclined towards the position near the wind power inlet.

[0010] Preferably, the upper end of the drainage trough is provided with a baffle, the baffle is inclined, and the end of the baffle away from the wind power inlet is inclined upward, while the lower inclined end of the baffle is fixed to the inner wall of the drainage trough. The upper end of the drainage trough away from the wind power inlet is provided with a groove for the baffle to fit.

[0011] Preferably, a control mechanism is provided in the drainage interlayer. The control mechanism includes a top plate and a waterproof electric push rod. The waterproof electric push rod is fixedly installed at the bottom of the drainage interlayer, and the upper end of the waterproof electric push rod is fixedly connected to the bottom of the top plate.

[0012] The top plate is a magnetic plate, the baffle is a stainless steel plate, and the end of the baffle near the wind input port is equipped with an elastic section.

[0013] Preferably, a support rod is fixedly provided on the upper surface of the top plate, a rotating baffle is rotatably provided at the upper end of the support rod, a torsion spring is provided at the rotatable connection, and the rotating baffle is sealed and fitted to the lower end of the drainage groove.

[0014] Preferably, the bottom surface of the drainage interlayer slopes downwards from one end of the wind inlet towards the end closer to the wind outlet.

[0015] Preferably, a water collection tank is installed at the lower end of the air duct. The water collection tank is located at the end of the air duct near the air outlet. A converging port is provided at the lower end of the air duct. A water collection chamber is provided inside the water collection tank. The upper end of the converging port is connected to the interior of the drainage interlayer, and the lower end of the converging port is connected to the interior of the water collection chamber.

[0016] The water collection tank is equipped with a water pump. The input end of the water pump is connected to the water collection chamber inside the water collection tank. The output end of the water pump is connected to a humidification pipe. The end of the humidification pipe away from the water pump is connected to an atomizing nozzle. The atomizing nozzle is inserted into the interior of the air outlet.

[0017] Preferably, the water collection tank is equipped with a filter box inside, which is located between the collection port and the water pump.

[0018] Preferably, the filter box is a rectangular box structure with an opening at the top. The bottom surface of the filter box is provided with grid holes.

[0019] Preferably, a magnetic block is provided on the side of the water collection tank and below the rectangular opening.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. In this invention, condensate flows into the drainage interlayer through the drainage channel. The amount of condensate in the wind channel is small and will not accumulate and affect the wind speed, thereby reducing the energy consumption of long-distance wind power transmission.

[0022] 2. In this invention, a water-blocking area S is also formed between adjacent baffles to prevent condensate from flowing towards the air inlet or air outlet. Condensate can flow directly into the drainage trough from the inclined opening of the corresponding baffle, instead of continuing to flow along the bottom of the air channel and affecting the air force. This also reduces the problem of poor HVAC effect caused by condensate absorbing heat from the air force.

[0023] 3. In this invention, the elastic segment can be elastically deformed, allowing the baffle to rotate within a certain range. When the baffle rotates and fits into the groove, the bottom of the wind channel is a flat surface, and the upper end of the drainage groove is completely sealed. The flat surface is conducive to wind power transmission and can be used according to actual conditions.

[0024] 4. This invention allows for easy control of the opening and closing of the drainage channel and the tilt of the baffle according to actual needs;

[0025] 5. In this invention, after the condensate is discharged into the drainage jacket, the baffle is rotated to reset, which avoids the effect of wind entering the drainage jacket and achieves the purpose of one-way water inflow.

[0026] 6. The purpose of humidifying the wind at the user end in this invention is not only to make it easier to control the degree of humidification, but also to improve the efficiency of wind power transmission;

[0027] 7. The present invention utilizes the structural design of the water collection tank to achieve the purpose of periodic automatic maintenance of the filter box. Attached Figure Description

[0042] This invention provides, for example Figures 1-13 The diagram illustrates an airflow guiding device for a building duct. This device addresses the problem of water droplets adhering to the walls of existing building heating and ventilation ducts, which affects airflow speed when cold or hot air is being circulated.

[0043] For details, please refer to Figure 1 As shown, the system includes a duct 1, one end of which is a wind inlet 2 for cold or hot air to enter, and the other end of which is a wind outlet 3 for cold or hot air to exit. The wind inlet 2 is usually connected to a centrifugal fan or an axial fan. The heat source generated by the boiler or the cold source generated by the compression refrigeration device is transported to the duct 1 by any of the above-mentioned fans, thereby forming hot or cold air. The air is then transported to the user end through the duct 1 of a suitable length, and the wind outlet 3 leads into the indoor space of the user end.

[0044] refer to Figures 2 to 3As shown, duct 1 is typically a rectangular ventilation duct, which has good spatial adaptability and can be easily installed along walls, ceilings, and other spaces, closely fitting the building structure and effectively utilizing limited space. In addition, rectangular ducts have greater flexibility in branching and connection. Through reasonable diameter reduction and bend design, air can be precisely distributed to different rooms and areas. Of course, there are also its disadvantages. Although the investment cost of rectangular ducts is higher, their thermal insulation performance is better, which can reduce the long-term heating and cooling maintenance costs.

[0045] There are also usually circular pipes; you can set them up according to your actual needs.

[0046] refer to Figure 5 As shown, the air duct 1 is provided with an air channel 10 inside. Cold or hot air entering from the air inlet 2 flows through the air channel 10 and is discharged from the air outlet 3.

[0047] In this invention, a drainage interlayer 11 is provided at the bottom of the air duct 1. The drainage interlayer 11 is separated from the air channel 10 by a guide plate 12. A drainage groove 1201 is provided on the guide plate 12. When the hot air introduced into the air duct 1 produces condensate that hangs on the wall, the condensate will drip onto the guide plate 12 and then flow into the drainage interlayer 11 through the drainage groove 1201. The amount of condensate in the air channel 10 is small and will not accumulate and affect the wind speed, thereby reducing the energy consumption of long-distance wind power transmission.

[0048] Furthermore, the drainage channel 1201 is arranged at an angle, with one end of the drainage channel 1201 leading into the drainage interlayer 11 tilted in the opposite direction to the wind inlet 2. Since hot air or air flowing through the wind channel 10 flows from the wind inlet 2 to the wind outlet 3, which is exactly opposite to the tilt direction of the drainage channel 1201, it ensures that the wind will not enter the drainage interlayer 11 through the drainage channel 1201, thus achieving the effect of isolating the wind and condensate.

[0049] refer to Figure 12 As shown in the figure, during the verification process, it was found that although the tilt direction of the drainage channel 1201 is opposite to the direction of wind power delivery, a small portion of the wind power will still circulate in and out of the drainage interlayer 11 through the drainage channel 1201, consuming a portion of the wind power. Therefore, the present invention also provides a baffle 1202 at the upper end of the drainage channel 1201. The baffle 1202 is arranged at an inclination, with the end of the baffle 1202 away from the wind power input port 2 tilted upwards at an angle between 1 and 5°. During the delivery process, the wind power inside the wind channel 10 can pass along the upper surface of the baffle 1202 and be discharged through the wind power outlet 3, making it less likely to flow back into the drainage channel 1201.

[0050] refer to Figure 13As shown, multiple drainage channels 1201 are appropriately arranged according to the length of the air duct 1. The multiple drainage channels 1201 are set at equal distances. A water-blocking area S is also formed between adjacent baffles 1202 to prevent condensate from flowing towards the air inlet 2 or the air outlet 3. The condensate can flow directly into the drainage channel 1201 from the inclined opening of the corresponding baffle 1202, and will not continue to flow along the bottom of the air duct 10 and affect the air force. It also reduces the problem of poor HVAC effect caused by the absorption of heat from the air force by the condensate.

[0051] refer to Figure 7 and Figure 8 As shown, an elastic section 1204 is provided at one end of the baffle 1202 near the wind input port 2, and a groove 1203 is provided on the inner wall of the upper end of the drainage channel 1201 away from the elastic section 1204. The elastic section 1204 can be elastically deformed, so that the baffle 1202 can rotate within a certain range. When the baffle 1202 rotates and fits into the groove 1203, the bottom of the wind channel 10 is a flat surface, and the upper end of the drainage channel 1201 is completely sealed. The flat surface is conducive to wind transmission and can be used according to actual conditions.

[0052] refer to Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown, a control mechanism 13 is provided in the drainage interlayer 11. The control mechanism 13 is used to control the tilt state of the baffle 1202. The control mechanism 13 includes a top plate 1301 and a waterproof electric push rod 1302. The waterproof electric push rod 1302 is fixedly installed at the bottom of the drainage interlayer 11, and the upper end of the waterproof electric push rod 1302 is fixedly connected to the bottom of the top plate 1301. The top plate 1301 is a magnetic plate, and the baffle 1202 is a stainless steel plate. When the waterproof electric push rod 1302 pushes the top plate 1301... When 01 rises, the top plate 1301 approaches the baffle 1202, and the top plate 1301 can attract the baffle 1202 to rotate and seal the upper end of the drainage channel 1201; when the waterproof electric push rod 1302 drives the top plate 1301 to fall, the top plate 1301 and the baffle 1202 move away from each other. After the baffle 1202 loses the attraction of the top plate 1301, it is reset by the elastic section 1204 and maintains the tilted state, which makes it easy to control the opening and closing of the drainage channel 1201 and the tilt of the baffle 1202 according to actual needs.

[0053] Furthermore, a support rod 1303 is fixedly installed on the upper surface of the top plate 1301, and a rotating baffle 1304 is rotatably installed at the upper end of the support rod 1303. A torsion spring is installed at the rotatable connection. The rotating baffle 1304 is attached to the lower end of the drainage trough 1201 by the force of the torsion spring, which seals the lower end of the drainage trough 1201. When condensate enters the drainage trough 1201, it will accumulate in the drainage trough 1201. After accumulating to a certain amount, the rotating baffle 1304 tilts due to the gravity of the condensate, opening the lower end of the drainage trough 1201. The condensate is discharged from the lower end of the drainage trough 1201 into the drainage jacket 11. After the condensate is discharged into the drainage jacket 11, the rotating baffle 1304 returns to its original position, preventing wind from entering the drainage jacket 11 and achieving the purpose of one-way water inlet.

[0054] In actual use, multiple support rods 1303 can be connected to a top plate 1301 at the same time, which makes it convenient to control the opening and closing of multiple drainage channels 1201 at the same time, thereby reducing the number of waterproof electric push rods 1302 and reducing costs.

[0055] When users use air duct 1, they usually require the airflow to have a certain humidity. The usual practice is to adjust the airflow to a suitable humidity before delivering it to the user. However, when airflow is delivered through air duct 1 of different lengths, the humidity in the airflow will increase or decrease accordingly. When the humidity of the airflow increases, the viscosity of the airflow will increase, which will lead to increased airflow resistance and thus affect the delivery of airflow. Therefore, the existing methods of humidifying airflow not only reduce the efficiency of airflow delivery, but also cannot accurately control the degree of humidification.

[0056] Therefore, this problem is solved by improving the drainage interlayer 11 in this invention. Specifically, refer to... Figure 6 and Figure 7As shown, the bottom surface of the drainage jacket 11 has a certain inclination, ranging from 3 to 8 degrees. A water collection tank 4 is installed at one end near the air outlet 3. The water collection tank 4 is fixedly installed at the bottom of the air duct 1. A converging port 101 is provided at the bottom of the air duct 1, connecting the drainage jacket 11 and the inside of the water collection tank 4. When condensate enters the drainage jacket 11, it will flow along the bottom surface of the drainage jacket 11 and eventually converge into the water collection tank 4. A filter box 8 is also provided in the water collection tank 4 to filter the condensate, so that the condensate... To meet the humidification water requirements, a water pump 15 is installed inside the water collection tank 4. The input end of the water pump 15 is connected to the water collection chamber 41 inside the water collection tank 4, and the output end of the water pump 15 is connected to the humidification pipe 5. The end of the humidification pipe 5 away from the water pump 15 is connected to the atomizing nozzle 6. The atomizing nozzle 6 is inserted into the air outlet 3. When the water pump 15 is started, it can atomize and spray the condensate water that has been recovered and filtered in the water collection chamber 41 from the atomizing nozzle 6, which achieves the purpose of humidifying the air at the user end. This not only makes it easy to control the humidification level, but also improves the efficiency of air delivery.

[0057] refer to Figure 7 , Figure 10 and Figure 11 As shown, the filter box 8 is a rectangular box structure with an opening at the top. The bottom surface of the filter box 8 is provided with a grid hole. The inside of the filter box 8 is filled with activated carbon filter blocks 81. The filter box 8 is located between the water pump 15 and the collection port 101. A rectangular opening 7 is provided on one side of the water collection tank 4. The filter box 8 is movably engaged in the rectangular opening 7. A waterproof electric cylinder 14 is hinged to the end of the filter box 8 away from the rectangular opening 7. An installation groove 42 is provided on the inner wall of the water collection tank 4. The waterproof electric cylinder 14 is fixedly installed in the installation groove 42. When the waterproof electric cylinder 14 pushes the filter box 8 out, it is convenient to clean the impurities collected in the filter box 8. A magnetic block 9 is provided on the side of the water collection tank 4 and below the rectangular opening 7. When the filter box 8 is completely pushed out of the rectangular opening 7, the magnetic block 9 attracts the filter box 8 to rotate, so that the impurities on the filter box 8 fall out automatically. After falling out, the waterproof electric cylinder 14 can reset the filter box 8, realizing the purpose of periodic automatic maintenance.

[0058] It should be noted that the present invention can also use manual addition of humidifying water or manual maintenance, which will not be elaborated upon.
