Description

Technical Field

[0001] The invention belongs to the technical field of fluid mechanics, and in particular relates to a directional reflux device. Background Art

[0002] The electric fans, air conditioners, heaters, range hoods, exhaust fans, air curtains, vacuum cleaners and other devices with wind drive in the prior art have both an air inlet and an air outlet. The air outlet generates positive pressure wind and the air inlet generates negative pressure wind. The principle is that the wind drive disperses and inhales the gas in an irregular manner and then blows it out from the device in a directional manner. Therefore, the wind at the blowing end can blow far, while the air suction end cannot suck the gas at a long distance. If the wind drive device is in a closed space, the blown airflow will diffuse from the positive pressure wind end to the surroundings and return to fill the negative pressure area at the air inlet end, and circulate continuously. Usually, high-temperature gas transfers heat energy to low-temperature gas; high-speed or high-pressure airflow transfers energy to low-speed or low-pressure airflow. For example, after the indoor air conditioner blows out cold air, the relatively hot air around the cold air will mix with the cold air for heat transfer. Since the air inlet source of the indoor unit enters through an uncontrollable non-directional dispersed path, the air in the entire room will flow, which means a large area of ​​heat transfer (the larger the indoor space, the greater the energy consumption of the air conditioner). The air conditioner will only shut down when the entire indoor air basically reaches the set temperature. People will be active indoors during the day, and the entire indoor temperature reaching the target temperature is exactly what people need. However, at night, people will only sleep in a small area such as the bed, so there is no need to cool down or heat up other spaces. However, air conditioners with prior art obviously cannot achieve this goal.

[0003] The existing air curtain machines commonly seen on the door frames of shopping malls are used to isolate the indoor and outdoor air temperatures. However, the air curtains produced by the air curtain machines must have air inlet and outlet. Since the air inlet source of the air curtain machine is an uncontrollable and non-directional path, the existing technology determines that outdoor hot air will inevitably be drawn into the room, or indoor cold air will leak to the outside. The air inlet of the air curtain machine comes from the outside or the inside, and the airflow of the air curtain will be mixed with the indoor and outdoor cold / hot air, and then flow back to the indoor or outdoor atmosphere through an uncertain path. The amount of heat transfer between air molecules in this process is very large, which is one of the energy losses of the air conditioner, and it may not be the case in the end. Backflow into the air inlet of the air curtain device, so the wind curtain in the prior art cannot replace the solid insulation to truly form an effective air curtain isolation wall; the wind curtain wall technology adopted by the existing range hood, since the suction wind source is an uncontrollable and non-directional path, the prior art determines that the wind source of the air inlet comes from the gas in a single indoor space. These gases are easily sucked by the range hood at the first time after being ejected from the air outlet, resulting in the smoke that is not sucked in by the range hood in time being sucked into the air inlet of the wind curtain wall device for the second time along with the indoor air, and cannot replace the solid pipe to form an effective wind curtain type air pressure isolation wall at the suction end of the range hood.

DETAILED DESCRIPTION

[0035] Embodiment 1: In Figure 1 and Figure 3 In the invention, the directional reflux device comprises at least an inlet (1) through which a fluid can pass, a tube cavity (9), and an outlet (2); the inlet (1) is arranged in a circle surrounding the outlet (2); the outlet (2) and the inlet (1) are oriented in non-opposite directions to each other; the inlet (1), the tube cavity (9), and the outlet (2) are connected in sequence; and a shell constituting the outlet (2) and / or the inlet (1) is fixedly and / or movably and / or integrally connected to the tube cavity (9). Figure 1 In the embodiment, the shells constituting the outlet (2), the inlet (1) and the cavity-type tube cavity (9) are integrated, the front shell (6a) and the side shell (6b) are combined to form the inlet (1) and the circular continuous outlet (2), and the front shell (6a), the side shell (6b) and the back shell (6c) are combined to form the cavity-type tube cavity (9), forming a directional reflux system.

[0036] The cavity of the tubular cavity (9) may also be replaced by a pipe.

[0037] An auxiliary port (3) communicating with the cavity-type tube cavity (9) is also provided at a portion of the shell of the cavity-type tube cavity (9) outside the encirclement of the outlet (2). Figure 1 In the embodiment, the auxiliary port (3) is arranged at the position of the back shell (6c), and the amount of fluid entering from the outside of the reflux system can be changed by adjusting the size of the auxiliary port (3).

[0038] By adjusting the angle between the outlet (2) and the central axis (7), the cross-sectional area of ​​the exhaled fluid end (13) and the system recirculation rate can be changed.

[0039] Embodiment 2: In Figure 3 In the embodiment, a plurality of connecting ribs (10) are provided between the front shell (6a) and the back shell (6c) so as not to hinder the passage of fluid in the entire system, so that the front shell (6a) and the back shell (6c) are integrally connected. Figure 6When the axial flow impeller drive device (5) and the shaft (8) are shown in the figure, the drive device (5) rotates in one direction to drive the fluid from the external space into the tube cavity (9) through the inlet (1), and then flows out to the external space through the outlet (2). When the fluid movement speed is sufficient, after a certain stroke in the form of a jet, a circular fluid end (11) appears. Since the inlet (1) is within the encirclement of the outlet (2), and the inlet (1) and the outlet (2) are oriented in the same direction, according to the principles of fluid mechanics, the fluid power sprayed to the fluid end (11) is lost or weakened, and is sucked by the negative pressure formed by the rotation of the drive device (5), and flows back into the inlet (1), and then is pushed to the tube cavity (9) by the positive pressure formed by the rotation of the drive device (5), and then is ejected from the outlet (2). This process is repeated.

[0040] The driving device (5) includes fans and / or pumps of axial flow, centrifugal, turbine, cross-flow, compression and other working modes according to different working principles, and also includes phase change and tank type fluid injection devices, which are devices that can change the fluid from static to dynamic or can change the flow speed of dynamic fluid.

[0041] Embodiment 3: In the design and manufacturing process, it is possible that the circular inlet (1) and / or outlet (2) are not limited to Figure 1 , Figure 2 and Figure 3 The continuous flat opening in the invention also includes a ring-shaped inlet (1) and / or outlet (2) separated by solid objects. Figure 4 In the embodiment, the outlet (2) is composed of three long strip outlets (2a), three solid partitions (4) are arranged between the three long strip outlets (2a), and the long strip outlets (2a) and the three partitions (4) together form a circular outlet (2); Figure 5 In the figure, the outlet (2) is composed of 90 circular outlets (2b) and dozens of partitions (4) to form a ring-shaped outlet (2); of course, the outlet (2) also includes other shapes.

[0042] Embodiment 4: In Figure 6 In the embodiment, the front shell (6a), the side shell (6b), the back shell (6c), the shaft (8) and the bracket (12) are integrally connected. When the driving device (5) is mounted on the shaft (8) and rotates in one direction, the driving device (5) sucks the fluid from the inlet (1) and pushes the fluid into the lumen, and the fluid is ejected from the outlet (2). By adjusting the angle between the fluid ejected from the outlet (2) and the central axis (7), the ejection stroke of the fluid and / or the diameter of the ejected fluid end (11) can be changed.

[0043] Embodiment five: Figure 7 and Figure 8In the figure, there is a double-outlet and single-inlet directional reflux device, wherein the outer circle outlet, i.e., the first circle outlet (2c), surrounds the first circle inlet (1a), and the first circle inlet (1a) surrounds the inner circle, i.e., the second circle outlet (2d). There is no inlet or outlet in the encirclement of the second circle outlet (2d). Of course, the second circle inlet and the third circle outlet can continue to be set, and the inlet and / or pipeline in the encirclement of the second circle outlet (2d) can also be disconnected from the lumen (9).

[0044] In the figure, the lumen (9) is connected to the first circle inlet (1a), the first circle outlet (2c) and the second circle outlet (2d). When working, the fluid is ejected from the first circle outlet (2c) and the second circle outlet (2d) at the same time. When the ejection force gradually weakens to the position of the fluid end (11), the external fluid will be absorbed or filled into the first circle inlet (1a). In addition, since the fluid ejected from the first circle outlet (2c) and the second circle outlet (2d) is in the form of a tubular fluid curtain, the direction is opposite to the fluid absorbed by the first circle inlet (1a), so the external fluid will enter from the position of the fluid end (11) along the channel between the two circles of the jet curtain of the first circle outlet (2c) and the second circle outlet (2d). This external fluid is basically the return fluid ejected from the first circle outlet (2c) and the second circle outlet (2d). Figure 8 In the figure, the dotted lines and arrows are schematic diagrams of the fluid movement route and direction. The returning fluid passes through the lumen (9) and then is ejected from the first circle outlet (2c) and the second circle outlet (2d), and the cycle continues. The ideal circulating fluid no longer or rarely mixes with the external fluid, but forms an independent fluid movement channel.

[0045] When a fluid inlet and / or pipeline that is not connected to the lumen (9) is additionally provided in the encirclement of the second circle outlet (2d), the fluid sucked into this additional inlet and / or pipeline does not circulate through the lumen (9) channel. The diameter of the second circle outlet (2d) is appropriate, and the external fluid moves from the circle center at the fluid end (11) to this additional inlet and / or pipeline. Ideally, the fluid will not mix with the fluid ejected from the first circle outlet (2c) and the second circle outlet (2d), thereby forming two independent fluid flow channels.

[0046] Embodiment 6: The lumen (9) or the inlet (1) or the outlet (2) is also provided with an electric heating device and / or a cooling / heating device or an evaporation / condensation device.

[0047] The lumen (9) or the inlet (1) or the outlet (2) is also provided with a sterilizing device and / or a filtering device and / or an oxygen generating device.

[0048] The above embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various changes and improvements made to the technical solutions of the present invention by professionals in the field shall all fall within the protection scope of the present invention.
