Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fluid transfer system, and more particularly to a fluid transfer system applicable to a high performance air cleaning device.

[0002]

2. Description of the Related Art As a conventional technique relating to fluid transfer, for example, Japanese Patent No. 1735847, "Diffusion preventive device for toxic gas" has been proposed. Further, in connection with this conventional technique,
As in -208435 "Artificial tornado generating mechanism and its mechanism", a plurality of pillars for blowing air are erected between the floor and the ceiling,
Furthermore, the upper ends of these pillars are shielded with an air hood, an air suction processing device is provided on this air hood or on the floor, and in an artificial tornado created between this air hood and a plurality of pillars,
There is a suggestion for people to smoke.

In the case of these prior arts, smoking is carried out in the swirling airflow which is constantly generated in the space, and the smoke circulates in the space during smoking, so that the clothes smells like cigarettes. There is a problem in that it feels uncomfortable due to sticking or swirling wind, and that it feels chilly especially in the cold season. Also,
Since the air hood and the plurality of pillars form a smoking place such as a hut where a plurality of people can enter, it tends to be a relatively large-scale facility. It is thought that some problems will be left, such as appropriate labor, equipment, or office remodeling.

[0004]

SUMMARY OF THE INVENTION In view of the above problems of the prior art, the present invention aims to provide a fluid transfer system that can be applied to, for example, air cleaning in a smoking space or a conference room.

[0005]

A typical feature of the fluid transfer device according to the present invention is that a plurality of fluid transfer devices are separately arranged so as to be individually movable, and each of them is independent or cooperates. The air blowing operation is performed, the rotating airflow is generated by the airflow from one fluid transfer device, and the suction portion of the other fluid transfer device is exposed below the rotating airflow.
In particular, when the present invention is applied as an air cleaning system or the like, a space where a part or the whole of a human body is located can be provided outside the rotating air flow.

[0006]

When the present invention is applied to, for example, a smoking space, a smoker can put a part or the whole of a human body on the outside of the swirling airflow generated by the air blower, so that the discomfort caused by the swirling airflow can be reduced. It is no longer felt, and smoke during smoking is efficiently sucked into the body of the air purifier and cleaned at high speed. Further, the device can be easily installed and moved, and the present invention can be applied not only to a smoking space but also to air cleaning in a conference room.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an application of the present invention to an air cleaning system. In a smoking place where a sofa or the like is arranged,
The air purifier 2 is arranged in the center, and four air blow columns 6 are arranged around it. Blower openings 7 and 8 are provided in the body and the upper end of the blower column 6, respectively, and the blower operation is performed by a built-in electric blower. Here, the blower column 6 is composed of a plurality of hollow tubes of different diameters, the upper small diameter portion is housed in the lower large diameter portion, and can be expanded and contracted in the axial direction. This is because when the air purifier 2 is installed on the floor surface 13 and the blast column 6 is extended vertically upward, the height of the blast column 6 is adjusted according to the height of the ceiling of the smoking room or the conference room. It is possible to reduce the transportation cost of the product by adjusting the expansion and contraction and downsizing the packaging.

FIG. 2 shows the internal structure of the air purifier 2. A suction port 2B having a preliminary filter is opened on the upper end surface of the main body 2A, and an exhaust port 10 and a rectification of exhaust gas are provided at the bottom of the main body 2A. Plates 12 and wheels 14 for moving the floor surface 13
Is provided. Further, a filter body 18 for collecting dust is built in on the upper suction side of the electric blower 17 that rotates the impeller 16 by the electric motor 15. This suction device 17
The air is transferred (intake and exhaust) by a manual switch by the user or an automatic control device using a smoke sensor or a human sensor. When the suction device 17 operates, air is sucked into the main body 2A from the suction port 2B by the suction force Fs, is cleaned by the filter body 18, and then the electric motor 15 is cooled and discharged from the exhaust port 10. The rectifying plate 12 rectifies the exhaust gas so that the exhaust gas flows along the floor surface 13.

On the other hand, when the air purifier 2 is started, the air blower 6 around it receives a wireless control signal from an optical remote controller or the like to start the air blow operation. From the blower column 6 is blown out substantially horizontally from the opening 7 of the body part, that is, so as to have a velocity component in a direction perpendicular to the central axis of the blower column 6,
It is designed to blow upward from the opening 8 at the upper end by an angle θ.

FIG. 3 is a view of FIG. 1 seen from above and shows the outflow direction of the air from the openings 7 and 8 of the blower column 6. For example, if the outflow direction from any blast column 6A is
The air is blown slightly inward so as to form an acute angle φ with respect to the plane 20 that includes the central axes of both the other adjacent air-blowing columns 6B closest to the outflow direction side of A. That is, the extension line of the blowout air from any conduit 6 (for example, the conduit 6A) is opened so as to intersect the extension line of the blowout air from the adjacent conduit 6B. Therefore, the air blown out from the opening 7 has a velocity component Vc directed from the conduit 6A to the adjacent conduit 6B and an inward velocity component Vr. Here, the four conduits 6A, 6B, 6
Since the outflow air from C and 6D perform the same action, respectively, the sum of the velocity components Vc becomes a rotation moment, and a rotary airflow enclosing the air cleaner 2 inside the four conduits 6 is generated. At the same time, due to the synergistic action of the suction force Fs and the centripetal force Vr by the suction device 17 of the air purifier, the air swirls downward in the space surrounded by the four ventilation columns 6A, 6B, 6C, 6D. Therefore, it is efficiently sucked into the air purifier 2 without being diffused.

Next, referring to FIG. 4, the flow state of air in the upper end portion of the blast column 6 will be described. Blower 6 Opening 8 at the top
From above, as described above, the angle θ is upward and the angle φ is
Only toward the inside, air blows out at a speed Ve. That is, the air blown from the upper end surface of the blast column 6 has velocity components in a direction perpendicular to and parallel to the central axis of the conduit. Therefore, the air at a position separated from the tip of the conduit 6 by a height h is also affected by the upward velocity component Vv1 of the velocity V1 and the horizontal velocity component Vh1. here,
By setting the angle θ sufficiently smaller than 45 degrees (θ << 45 degrees), Vh1 can be made sufficiently larger than Vv1. Here, the suction force Fs of the air purifier 2 is sufficiently larger than the upward component force Vv1 of the blown air.

Further, as shown in FIG. 5, the air blown out from the openings 8 at the upper ends of the four blast columns 6 has respective horizontal component forces of velocities V1, V2, V3 and V4 in the upper direction separated by h. A rotational moment is given to the air above the main body by the couple generated in Vh1, Vh2, Vh3, and Vh4. Therefore, the air above the blast column 6 also swirls in advance, becomes a spiral shape, and is sucked into the space surrounded by the four conduits 6 without being diffused.

Next, FIG. 6 is a development example of the present invention, and shows the positional relationship between the smoker 22, the air purifier 2, and the air blown from the air blower column 6. Electric blower 24 built in the blower column 6
As a result, the air is sucked through the opening 26 on the lower end surface and is blown from the body and the upper end as described above. Here, the opening 7 of the body portion of the blower column 6 is provided above the head of the smoker 22 by a height H, and the suction port 2B of the air purifier 2 is also
It is opened above the smoker 22. For this reason, a swirling airflow is generated above the smoker 22, and during smoking, the smoke of the cigarette having a high temperature becomes an ascending airflow and flows into the swirling airflow, and then converges into a swirl and the air purifier 2 Is sucked in. Therefore, since the smoker 22 can smoke outside the swirling airflow, problems such as feeling uncomfortable due to the swirling airflow such as cold and smelling cigarette smoke on clothes are eliminated.

FIG. 7 shows another application example of the present invention. The suction port 3 provided on the upper surface of the main body 30A of the air cleaner 30.
Four expandable blower columns 36 are erected around 0B. The blast from the blast column 36 is the main body 30A.
A part of the exhaust air of the electric blower built in the air blower is supplied, or the electric blower is individually built in the blower column 36. Here, the air blow from the air blow column 36 is performed in the same manner as the air blow of the air blow column 6 described in FIGS. 3 to 5.
In the space inside the four air blow columns 36 of the air cleaner 30, swirling rotating airflow is also generated, and air is sucked into the main body 30A from the suction port 30B, and an air cleaning action is performed.

FIG. 8 shows another application example of the present invention.
The air cleaner 30 of FIG. 7 is installed in the vicinity of the center of the smoking space surrounded by the above-mentioned four blast columns 6 and the two are used in combination. Here, the air flow column 36 of the air purifier 30 is exposed to the rotating airflow generated by the air flow column 6 at a height H above the smoker 22. In this case, the rotating airflow generated by the air blower column 6 is continuous with the rotating airflow generated by the air blower column 36 of the air cleaner 30,
It becomes a converging swirl flow and is sucked into the main body 30A to perform an air cleaning action. This allows the main body 30A of the air purifier 30 to be miniaturized while generating the rotating airflow by the air blower column 6 away from the floor surface 13 upward. Further, a flow control device for adjusting the supply air is attached to the air blower column 6 or the air blower column 36, or the air blower column 36 is configured to be expandable and contractible, so that an optimum rotating convergent air flow can be obtained according to the smoking space or the ceiling height of the conference room. It is also possible to generate and efficiently perform the air cleaning action.

Further, in the above-described embodiment, the example in which the blast columns 6 and the blast columns 36 are four is used, but the present invention is not limited to this, and, for example, the blast columns are blown from a plurality of three or more blast columns. hand,
A similar effect can be obtained by generating a rotationally convergent flow in a smoking space or a conference room.

In the above embodiment, the filter body 18 is installed on the suction side above the suction device 17, but the filter body 18 may be provided on the discharge side of the suction device.

Further, although the openings 7 and 8 of the conduit 6 are circular in the above embodiment, the present invention is not limited to this, and may be elongated holes or slits.

Further, although the above-mentioned embodiment has explained the application to the air cleaning system, the present invention is not limited to this, and other fluid transfer such as a dust collecting device of a vacuum cleaner, a water filtering device, or a powder mixed fluid is carried out. It may be used in the system.

[0021]

A transfer device can be provided. In particular, when used as an air cleaning device for a smoking space, a smoker does not need to be present in a space in which cigarette smoke swirls, and does not feel discomfort due to swirling airflow.
