Description

Fluid suction device

The present invention relates to a method for maximizing the suction efficiency by inducing a rotating vortex phenomenon of a fluid to be inspected in a suction process while forcibly sucking a fluid such as air or water present in the room or outdoor to another point Technology,

In addition, the present invention relates to a technique for adjusting the suction force and the intake range freely according to the installation place by making its length adjustable.

Generally, most of the air suction devices are used for the removal of toxic gas due to fire or the like or the smoke generated during the cooking process in the food cooking space in situations where ventilation is required indoors or outdoors.

In addition to air, a water suction device is used even in the case where a fluid such as water present at a specific point has to be forcedly discharged to another point.

Such a fluid suction device has a basic principle of forcibly sucking the intake target fluid present in the space and discharging it to another point,

The conventional suction apparatus is constructed such that a suction force is given to the inside of a suction duct having a shape such as a pipe or the like, the suction fluid formed at the corresponding point is forcibly sucked into the suction duct, and then sucked and discharged in the opposite direction.

However, in the conventional suction device, since the fluid to be sucked in the suction process is simply moved in the linear direction along the path of the suction duct, the suction force depends only on the output of the suction motor or the pump.

Therefore, since the proper suction force differs depending on the amount of the fluid to be sucked, the moving distance, and the like, a motor or a pump for realizing the sucking force must be provided at that time.

Also, since the length of the suction duct is always fixed in the process of sucking the fluid to be sucked, there is a problem that a suction duct having different lengths is required to be installed according to the volume of the space to be installed, the distribution area of the fluid to be sucked.

In recent years, when the intake fan is rotated by the rotating intake fan, external air is introduced into the intake fan and then discharged to the other side. As the external air is rotated by the intake rotor, Technology has been proposed.

However, this prior art is disadvantageous in that the intake rotor is integrally installed inside the revolving intake fan, so that the intake can only be performed at a predetermined point in the structure, and the intake point and range are extremely limited.

Therefore, when the distribution range of the fluid to be sucked is wide, a plurality of suction devices must be inevitably installed, and if not, the suction time can not be shortened.

That is, if the suction device is fixedly installed, the prior art can exert an effect only on the suction of the fluid to be sucked in the vicinity thereof, while it suffers from difficulty in sucking the fluid to be sucked in the point where the suction force is insufficient.

That is, since it is impossible to apply the suction force to various points in the installation state, there is a disadvantage that the suction range is extremely limited.

In addition, since the intake vortex inducing the rotation of the fluid is directly installed in the rotating intake vortex, the vortex development time due to the intake vortex is very short during the process of being discharged after the intake target vortex is sucked.

Therefore, it is difficult to secure sufficient time to induce a sufficient vortex phenomenon, which results in increasing the effect of improving the intake efficiency by the vortex phenomenon.

Korean Registered Utility Model No. 20-0310048 (2003. 03. 27)

The present invention has been proposed in order to solve the problems of the prior art,

Basically, it sucks the fluid to be sucked and discharges it to another point. It induces the swirling phenomenon of the fluid to maximize the suction efficiency,

Thereby improving the suction efficiency and maximizing the range of the suctionable points compared with the conventional suction structure.

In addition, by improving the installation structure of the vortex guiding member, it is possible to ensure the vortex induction time of the fluid to be sucked, thereby achieving an effect of improving the suction efficiency through a sufficient vortex phenomenon.

To this end,

Wherein the suction port is formed in a hollow tube shape having a suction port formed at one end thereof and a discharge port formed at the other end thereof, the suction port being connected to the suction drive part, and the suction port of the suction pipe, And a vortex guiding member for guiding a vortex by allowing the suction target fluid flowing into the suction pipe to rotate in the course of passing through the discharge port.

And the vortex guiding member may be formed of at least one of a blade and a spiral groove formed around the discharge port.

Further, the length of the suction pipe can be variable, so that the length of the interval between the discharge port and the suction port can be adjusted.

And the diameter of the suction pipe may increase from the discharge port toward the suction port.

Further, the suction pipe is divided into a plurality of divided pipes by a predetermined length, and the end portions of the plurality of divided pipes are overlapped with each other. Each of the divided pipes can be moved back and forth individually, and the length of the suction pipe can be adjusted by a telescopic structure as a whole.

In this case, the sliding rail and the sliding protrusion are mutually inserted in the overlapped section between the respective divided pipes, and the sliding equivalent can be linearly moved within the sliding rail forming section of the other divided pipes in the process of moving the divided pipes back and forth.

According to the present invention,

Basically, as the suction target fluid formed on the outside of the suction pipe by the suction force of the suction inlet is introduced into the suction pipe through the suction port and then discharged through the discharge port, as the suction target fluid is rotated by the vortex guiding member, Of course, since the fluid to be sucked outside the suction port can be continuously vortexed, the suction and discharge efficiency of the sucked fluid can be maximized by the vortex phenomenon.

At this time, as the vortex guiding member is formed in any form of the blade shape, the spiral projection, or the spiral projection, the vortex of the suction target fluid can be smoothly and accurately performed.

In addition, since the length of the suction pipe can be varied, the suction target fluid formed at a distance or a distance from the inlet of the suction inlet can be sucked, so that the suctionable range can be maximized by the variable length structure of the suction pipe .

At this time, since the suction pipe has a telescopic structure as a whole, the variable length structure can be implemented simply and accurately.

In addition, since the diameter of the suction pipe increases from the discharge port toward the suction port, the pressure is lowered toward the discharge port during the suction process, thereby further improving the suction efficiency into the suction pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The suction device 1 according to the present invention includes a suction inlet 100 and a suction pipe 200 and a vortex guiding member 300 as shown in FIGS. 1 to 3.

First, the suction port assembly 100 generates a suction force necessary for suction of a fluid to be sucked, which is formed outside the suction device, and may be in the form of a known suction motor or a suction pump, and is located at one side of the suction device.

At this time, the suction inlet opening portion 100 may be installed in a separate case (not shown) or in a state of being positioned outside the suction device, to provide a suction force to the suction pipe 200 described later.

Also, since the shape and the installation structure of the inlet opening 100 are not limited to a specific structure and can be variously modified as long as the structure can provide an intake force necessary for sucking the fluid to be inhaled, ) Is simply shown in the form of a schematic diagram.

A suction pipe (200) is connected to the suction port (100).

The suction pipe 200 is a part where suction fluid is collected and sucked, and at the same time, a swirling flow of the sucking target fluid is formed. The suction pipe 200 is formed as a hollow tube as a whole and has a suction port 210 through which the suction fluid flows, And a discharge port for discharging the introduced fluid to be sucked is formed in the end portion.

The suction pipe 200 has a structure in which the suction force applied from the suction mouth portion 100 is formed over the entire section from the discharge mouth 220 to the suction mouth 210 as the discharge mouth 220 is connected to the suction mouth portion 100 .

At this time, the suction pipe 200 has various structures for enhancing the suction efficiency, and has a large diameter difference structure and a variable length structure.

For this, the suction pipe 200 is formed such that its diameter increases from the end of the discharge port 220 toward the opposite suction port 210.

With this structure, the overall pressure in the suction pipe 200 is basically lower than the external pressure in the suction process, and the pressure in the vicinity of the discharge port 220 where the suction force is initially generated is the lowest, The fluid to be sucked is smoothly introduced into the suction pipe, and at the same time, the sucked inflow fluid can be quickly passed through the discharge port.

In this state, the suction pipe 200 is not divided into a single piping structure but has a structure divided into sections, so that the suction pipe 200 is divided into a plurality of divided pipes 230 at intervals along the longitudinal direction, Are connected to each other in a state in which the end portions of the end portions are arranged along the longitudinal direction.

At this time, each of the divided tubes 230 has a telescopic structure as a whole because the one end of each of the divided tubes 230 located at the front and the rear is configured to be movable back and forth in a mutually superimposed state, The entire length of the suction pipe 200 can be increased or decreased according to the moving direction of the suction pipe 200.

Since the entire length of the suction pipe can be varied, if the length of the suction pipe is increased even if the position of the suction hole 100 is fixed, the suction target fluid located remotely from the suction hole 100 can be easily sucked. It is possible to maximize the suctionable range with respect to the suction port 100 as a reference.

Therefore, compared with the prior art in which the suction point is always fixed, the applicable fields can be diversified and high suction efficiency can be obtained.

The sliding rails 232 and the sliding protrusions 234 are formed on the inner circumferential surface and the outer circumferential surface of each of the partitioning pipes 230 so that the respective divided pipes 230 are overlapped with each other, The sliding protrusions 234 of the other divided pipes are inserted into the sliding rails 232 of the other divided pipes.

In this case, since the sliding rail 232 has a linear groove structure along the longitudinal direction of the corresponding divided pipe, the sliding protrusion 234 is slidably inserted into the sliding rail 231 during the linear movement of the divided pipes for adjusting the length of the suction pipe 200 232), it is possible to smoothly move the split pipe smoothly, and also to prevent unwanted separation between the split pipes 230.

The concave and convex portions 235 may be repeatedly arranged along the longitudinal direction of the sliding rail 232 while the concave and convex portions 235 are formed on the bottom surface of the sliding rail 232 as necessary, The end portion of the sliding protrusion 234 rides over the concave and convex portions 235 of the sliding rail 232 in a stepwise manner during the linear movement of the partitioning tube 230, However,

As a result, the length of the suction pipe 200 can be adjusted step by step by a predetermined length, so that the desired length condition can be stably maintained.

As described above, according to the present invention, since the length of the suction pipe 200 can be freely adjusted, unlike the conventional technique, the suction port 210 of the suction pipe 200 is directly positioned at the point where the suction target fluid exists, So that the induction of the suction force is improved correspondingly.

In this suction pipe (200), a vortex inducing member (300) is further installed.

As the fluid to be sucked is swirled in the process of flowing the fluid to be sucked into the suction pipe and passing through the discharge port 220, the vortex guiding member 300 finally sucks the inhaled fluid, which is located around the suction pipe 210, Thereby inducing a vortex flow of the target fluid, thereby maximizing the suction and discharge efficiency by the vortex.

Since the vortex guiding member 300 is positioned at the center of the discharge port 220 in the suction pipe and is formed in the form of a blade or a spiral groove or a spiral protrusion, the vortex guiding member 300 300, so that a vortex phenomenon occurs naturally.

Of course, the structure and the shape of the vortex inducing member 300 are not limited. When the suctioned fluid to be sucked is vortexed in the process of passing through the discharge port, the vortex of the fluid around the suction pipe as well as the outer periphery suction target can be guided Various modifications can be applied.

According to the structure described above,

The suction force acts on the suction port 210 through the discharge port 220 of the suction pipe 200. As a result, as the pressure inside the suction pipe 200 becomes lower, Is introduced into the suction pipe (200) and then moved toward the discharge port.

At this time, as described above, since the diameter of the suction pipe decreases toward the discharge port, the suction efficiency of the suctioned fluid can be further improved due to the pressure drop due to the diameter reduction.

In addition, the suction target fluid passing through the discharge port 220 after the suction is vortexed and discharged in a spiral shape while being in contact with the surface of the vortex inducing member 300 located in the discharge port 220.

Since the vortex phenomenon is gradually applied to the suction target fluid in the suction pipe 200 and further to the suction target fluid around the suction port 210, The suction and discharge efficiency can be maximized.

In this state, when the fluid to be sucked is located at a distance from the inlet port, the length of the suction pipe 200 is increased so that the suction port 210 is positioned to the corresponding point. Consequently, do.

Since the length of the suction pipe can be varied in this manner, the range of suction can be maximized.

In addition, unlike the prior art, the vortex guiding member 300 is installed in a separate suction pipe rather than in the inlet of the suction port, so that the suction of the external suctioned fluid can be concentrated only through the suction port.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be considered to fall within the scope of protection of the present invention.
