PURPOSE:To facilitate a formation of a zone enclosed by a film-like injection flow and enable an efficient adjustment of inner fluid to be attained by a method wherein a fluid adjusting device is comprised of a guide member having an inclined guide surface slanted from its central part to its outer circumferential edge and a fluid adjusting means for injecting fluid toward a guide surface. CONSTITUTION:A guide member 1 has a cone-like guide surface la extending toward a fixed surface while being inclined in a radial manner so as to descend from its central part toward an outer circumferential edge. A plurality of adjusted diffusers 47 are spaced apart along a circumferential direction at a top part of a casing 41. An injection flow C discharged from the adjusted diffusers 47 strikes against a guide surface la and flows downwardly while being dispersed toward the outer circumference 1c along the guide surface la. The air becomes an annular air curtain blown from an entire circumference of the outer circumferential edge 1c of the guide member 1 toward a downward lower part. Subsequently, the air becomes gradually flowing toward a lower side. The air strikes against the fixed surface 3 and is directed toward the outside part of a zone 9 along the fixed surface 3. The zone enclosed by the film- like injection flow is formed between the guide member 1 and the fixed wall. Fluid in the zone 9 is sucked by a fluid adjusting means 4 and adjusted.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a local closed space surrounded by an air current in the atmosphere,
That is, the present invention relates to a zone forming fluid regulating device suitable for forming a zone and at the same time conditioning the air within the zone.

(Prior art) A device for removing 1+ type dust shown in Fig. 10 was developed in 1982.
It is known from the publication No.-111.700.

In this radioactive dust removal device, purified air purified by a processing device 01 is energized by a blower 02, and - a limited passage 06 is formed between an outer pipe 04 and an inner pipe 05 of a heavy duct 03.
The air is supplied to the center of the umbrella-shaped hood 07, diffuses radially in the process of passing through the internal flow path 0]3, and is blown out downward from the air outlet 03 on the outer periphery as an air curtain 09.

A local work space 01 surrounded by this air curtain 09 is formed in the room O, and contaminated air in the work space 011 is discharged from the contaminated air intake port 012 that opens downward at the center lower surface of the umbrella-shaped hood 07. The air is sucked into the inner pipe 05 and transferred to the processing device 01, where it is separated into contaminated solids and purified air.

(Problem to be Solved by the Invention) In the conventional device described above, a film-like airflow is blown downward from the air outlet 08 on the outer periphery of the umbrella-shaped foot 07.
In addition, since the amount of air blown out from the air outlet 08 and the amount of contaminated air sucked in from the air intake port 012 are equal, a short-circuit flow is likely to occur between the blown air flow and the intake air flow, and therefore a local Not only is it difficult to form the working space 011, but in order to enlarge this local working space 011, the diameter of the umbrella-shaped hood 07 should be increased, or the flow velocity of the film-like airflow blown out from the air outlet 8 should be increased. It must increase dramatically.

Furthermore, since the structure of the umbrella-shaped hood 07 is complicated and the double duct 03 must be used, there are problems such as not only increased cost but also troublesome handling and installation work.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and its gist is that the a zone surrounded by a guide member provided with an umbrella-shaped guide surface that is inclined from the center toward the outer periphery toward the fixed surface, and a film-like jet flowing out from the outer periphery of the guide member; The zone forming fluid regulating device is characterized in that it includes a fluid regulating means disposed inside the zone, which sucks in fluid in the zone, regulates it, and then jets it out toward the guide surface.

The guide member can also be supported by a column.

The guide member can also be suspended from above.

The guide member can also have a parasol-like foldable structure.

The guide member can also have a double structure.

The fluid regulating means may be an air conditioner, an air cleaner, a dust remover, or a combination thereof.

It is also possible to arrange the fluid conditioning means and the air conditioner outside the zone.

A table can also be installed above the air conditioner.

It is also possible to connect each air conditioner of a plurality of zone-forming fluid conditioning devices to one condensing unit installed outside the zone.

(Function) The fluid ejected from the fluid regulating means collides with the guide surface, changes its direction, and flows out from the outer periphery of the guide member as a film-like jet, and the zone surrounded by this film-like jet is the guide member. The fluid in this zone is drawn into and regulated by the fluid regulating means.

When the fluid regulating means is an air conditioner, an air cleaner, a dust remover, or a combination thereof, the air within the zone can be conditioned or purified.

(Example) One embodiment of the invention is shown in FIG.

In FIG. 1, 1 is a guide member, 3 is a fixed surface such as the ground or a floor surface, and 4 is a fluid regulating means such as an air conditioner.

The guide member 1 has an umbrella-shaped guide surface 1a extending radially downward from its center toward its outer periphery.

This guide member 1 is supported in a space 8 by a support 5 so as to be directly opposite the fixed surface 3 at a predetermined distance.

There is an air intake grill 42 inside the housing 41 of the air conditioner 4.
A heat exchanger 43 is disposed so as to face the heat exchanger 43, and an air blower 8!44 is disposed so as to be surrounded by the heat exchanger 43. This blower 44 is driven by a motor 45 supported by a support member 46.

A plurality of regulated air outlets 47 are arranged at intervals along the circumferential direction at the top of the housing 41, and these outlets 47 are arranged so that the blowing direction of the regulated air blown out from these outlets 47 can be freely changed. It has become. The lower end of the support column 5 passes through a bellows 51 at the center of the top of the housing 41, is inserted into the interior of the housing 41, and is supported by a support member 46.

A table 4 is attached to the upper part of the casing 41 via a vibration isolator 49, and an operation panel 50 is attached to the side surface of the casing 41 below the table 48.

This air conditioner 4 is disposed on a fixed surface 3 below the center of the guide member 1 inside a zone 9 to be described later,
Condensing unit 6 is arranged outside zone 9.

This condensing unit 6 is connected to the air conditioner Il & 4 via a refrigerant pipe 7, and a compressor 62 and a heat exchanger 63 are included in the casing 61 of this condensing unit 6.
A fan 64, an aperture 65, etc. for blowing air into the heat exchanger 63 are housed therein.

When the operation panel 50 is operated to operate the air conditioner 114 and the condensing unit 6 for cooling, the refrigerant discharged from the compressor 62 of the condensing unit 6 enters the heat exchanger 63, where it is mixed with the air sent by the fan 64. It condenses in the heat exchanger, expands adiabatically in the throttle 65, passes through the refrigerant pipe 7, enters the heat exchanger 43 of the air conditioner 4, evaporates here, and then passes through the refrigerant pipe 7 again to the condensing unit 6. and is sucked into the compressor 62.

At the same time, the blower 44 of the air conditioner 4 is rotationally driven by the motor 45, so that the air in the zone 9 enters the housing 41 through the air intake grill 42, and the heat exchanger 43
After being cooled while flowing through the air, the air is energized by the blower 44 and blown upward or diagonally upward from a plurality of regulated air outlets 47 .

The jet stream C discharged from the regulated air outlet 47 is directed to the guide surface 1a.
The air collides with the guide member 1, spreads along the guide surface 1a toward the outer circumferential edge 1c, gradually changes direction and becomes downward, and blows out obliquely downward from the entire circumference of the outer circumferential edge 1c of the guide member 1, forming an annular air curtain E. As it advances, it gradually changes its direction and faces downward, collides with the fixed surface 3, and heads along the fixed surface 3 toward the outside of the zone 9.

As a result, a local closed space surrounded by the air curtain E extending from the outer peripheral edge 1c of the guide member 1 to the fixed surface 3, that is,
A zone 9 is delimited within the space 8 between the guide member 1 and the fixed wall 3.

Since the annular air curtain E has the property of attracting and dragging the surrounding air, a recirculation flow D is generated within the zone 9, and the pressure within the zone 9 becomes lower than the pressure within the space 8. Thus, this negative pressure bends the streamlines of the air curtain E, and this negative pressure and the air curtain E
The streamlines of the air curtain E are determined so that the centrifugal force acting on the air curtain E is balanced.

During cooling operation of the air conditioner 4, the specific volume of air in the zone 9 becomes smaller, so the pressure in the zone 9 becomes lower, and therefore the zone 9 can be easily formed by the air curtain E.

Drain condensed on the surface of the heat exchanger 43 during cooling operation is discharged through the drain hose 52.

Note that if a dust filter or a deodorizing filter is disposed in the air flow path in the housing 41 of the air conditioner 4, the air in the zone 9 can be cleaned of dust and deodorized.

Since the inside of the zone 9 is partitioned from the outside space 8 by the air curtain E, it is possible to prevent noise from the outside space 8 from entering the zone 9 and to efficiently air condition or purify only the inside of the zone 9. Therefore, the equipment cost and operating cost of the air conditioner 814 can be reduced.

In addition, since the inside of the zone 9 is only partitioned from the outside space 8 by the air curtain E, the person M inside the zone can see through the air curtain E and have a field of vision in all directions. You can come and go freely.

As shown in FIG. 2, the guide member 1 can be folded like a parasol.

A piece 6 in which a plurality of main bones 60 are fixed to the upper part of the pillar 5 at the base end.
1 via a pin 63 so as to be rotatable. One end of a plurality of auxiliary bones 65 is pivotally connected via a pin 66 to a slider 64 that is fitted onto the support column 5 and moves up and down. A flexible membrane 68 made of cloth, synthetic resin, etc. is stretched over the plurality of main ribs 60. The slider 64 can be locked at a predetermined height of the support column 5 by a locking piece 69.

In case of strong winds, etc., the locking by the locking piece 69 is released and the slider 64 is moved downward, so that the main bone 6
0 rotates around the bin 63 and the flexible membrane 68 is folded.

As shown in FIG.
It can be attached to the lower end of the drawer 73 branching from the upper end, or it can also be attached to the lower end of the opening, door, or wire 75 hanging from the ceiling 74 of the building.

In addition, as shown in FIGS. 4 and 5, when the zone forming fluid regulating devices of multiple eclipses are disposed close to each other, the zone forming fluid adjusting device is arranged in the node 9 which is limited below each guide member 1. A plurality of air conditioners 4 installed in the air conditioner 4 can be connected to one condensing unit 6 via a refrigerant pipe 7.

Further, as shown in the sixth wa, the guide member 1 can be suspended close to the vertical wall 80. In this case, the guide member 1 is partially cut out and brought into close contact with the vertical wall 80. Note that by arranging the booster fan 81 inside the guide member 1, the zone 9 can be easily formed and the effect of stirring the air in the zone 9 can be improved.

Further, as shown in FIG. 7, the edge IC of the guide member 1 can be supported by a plurality of supports 82.

Furthermore, the guide member 1 can be shaped like a tent as shown in the eighth figure.

Further, as shown in No. 91, in order to improve the heat insulation properties of the guide member 1 and to narrow unnecessary space at the top inside the guide member 1, a membrane member 83 is stretched so as to connect the edge IC of the guide member l. You can also do it.

In this way, it is possible to save energy by improving heat insulation and reducing the air-conditioned space. Note that a heat insulating material 84 may be placed between the guide member 1 and the membrane member 83 in order to further improve the heat insulating property.

The case where a zone surrounded by an air curtain is formed in the atmosphere has been described above, but it is of course possible to form a zone surrounded by a jet of this fluid in any fluid such as gas or liquid. .

(Effects of the Invention) In the present invention, since the film-like jet flows out from the outer peripheral edge of the guide member in the radial direction and toward the fixed surface, the film-like jet flows between the guide member and the fixed surface. An enclosed zone can be easily formed, and since the zone is limited by an annular fluid film, the fluid within the zone can be efficiently adjusted by the fluid adjustment means.

When the fluid regulating means is an air conditioner, an air purifier, a dust remover, or a combination thereof, it is possible to condition and purify the air in the sink surrounded by an air curtain in the atmosphere, or to use a combination of these machines. In addition to being able to create a comfortable living space that is quiet and unexpected, it is possible to move in and out of the zone at will, with a field of view in all directions.
