[Problem that the invention attempts to solve]

An operator working near OA equipment
If you try to block the effects of heat emitted from office automation equipment by yourself, the reality is that you have no choice but to take measures such as setting up a lamp or changing your working position to a position where you do not come into direct contact with the heat flow emitted from the waste heat vent. It is. In addition, although the previously proposed devices mentioned above are effective to some extent, once they are installed, the installation position is fixed, or the devices are large-scale, so the operator cannot freely manipulate the layout. . Therefore, when it is necessary to change the layout of OA equipment or change the work desk, it is generally difficult and unnecessary to freely manipulate the waste heat treatment area and position in accordance with the change using known equipment. In such cases, processing may be problematic because the equipment itself is expensive.

The present invention aims to solve such problems.

[Means to solve problems]

The above-mentioned problem is that the cylindrical body stands on its own on the floor, a fan is housed inside the cylindrical body, and there is an air outlet at the upper end with the blowing direction facing upward, and an air suction outlet on the side of the lower body part of the torso. It consists of a cylindrical fan unit provided with an opening, a curtain having a width approximately corresponding to the height of the cylindrical fan unit, and a floor-standing winding rod for winding the curtain. In the interior of this invention, one edge of the curtain is fixed to a free-standing cylindrical fan unit with its width direction vertical, and this curtain is placed near OA equipment.
This problem can be solved by a device for removing waste heat from OA equipment.

In this case, it is more convenient to make the opening position and/or opening area of the air suction port of the cylindrical fan unit adjustable.

Embodiments of the present invention shown in the drawings will be described below.

〔Example〕

FIG. 1 is an overall perspective view showing an example of the OA equipment waste heat removal device of the present invention in which the cylindrical fan unit 1 is cylindrical. As shown in the figure, the device of the present invention is
a cylindrical fan unit 1; a curtain 2 having one edge fixed to the cylindrical fan unit 1;
It consists of a winding rod 3 that winds up the other edge of this curtain 2, and a cylindrical fan unit 1 and a winding rod 3.
Both stand upright on the floor by themselves. For this purpose, a suction cup 4 is attached to the bottom of the winding rod 3. Further, a plurality of casters 5 are attached to the bottom of the cylindrical fan unit 1 so that it can stand on its own in any position.

A fan 6 and a motor 7 therefor are housed inside the cylindrical fan unit 1. The motor 7 is connected to a power cord 8, and is turned on and off by a switch 9. An air outlet 10 is provided at the upper end of the cylindrical fan unit 1, with the air blowing direction facing upward, and an air intake port 11 is provided at the lower half of the body.
A grill is attached to the air outlet 10, and by adjusting the inclination of the grill, the blowing direction can be adjusted, but the discharge flow is still directed upward. The air suction port 11 is installed with a width less than half the circumference of the cylinder, and is adapted to suck air from only one side of the cylindrical fan unit 1.

The curtain 2 is a synthetic resin sheet such as a vinyl sheet or a nylon sheet, or a cloth curtain that allows relatively little air to pass through, and is of such a nature that it can be freely rolled up by a winding rod 3. Its width is approximately equal to the height of the cylindrical fan unit 1, and one edge is arranged so that the width direction is vertical and the cylindrical fan unit 1 is
Fixed. The fixed position is a position away from the position where the opening of the air suction port 11 exists, and is preferably close to the side edge of the air suction port 11. Reference numeral 12 denotes a curtain support, which can also stand on the floor by suction cups 13. This curtain support 12 has clips 14 and 1.
5 are attached so as to sandwich the upper and lower edges of the curtain 2. By attaching these curtain supports 12 to various parts of the stretched curtain 2,
Even if the length of the curtain becomes long, it can be prevented from loosening, and the direction of partitioning with the curtain can also be changed using the pillars 12. When the curtain 2 is stretched as shown in FIG. 1, when the fan 6 is driven, a suction flow is generated along the curtain as shown by the arrow in the figure, and the air is sucked into the air suction port 11, and the air is sucked into the air outlet. 10 toward the ceiling.

2 and 3 illustrate the manner in which the apparatus of FIG. 1 is used. When the computer disk 16 that generates waste heat is located near the operator's work desk 17 as shown in the figure, the curtain 2 is stretched with a slight gap left on the side of the waste heat port 18 (FIG. 3) of the disk 16. hand over. At this time, the cylindrical fan unit 1 is placed on the side away from the work desk 17, and the winding rod 3 is placed on the side close to the work desk 17. When the fan of the cylindrical fan unit 1 is driven with this arrangement, the heat flow coming out of the disk 16 is blocked by the curtain 2 and is drawn along the curtain 2 in the direction of the air suction port 11 of the cylindrical fan unit 1. The air is discharged from the air outlet 10 toward the ceiling. That is, the heat flow is concentrated in a direction away from the operator and radiated to the ceiling.

FIG. 4 shows a cylindrical fan unit 1 according to the present invention.
This figure shows another aspect of . In this example, a cylindrical fan unit 1 having a prismatic shape (having a flat hexagonal cross section) is used, and an air suction port 11 is provided on its flat side surface, and a blind plate 19 covering a part of the area of this air suction port 11 is provided. is attached to the front surface of the opening of the air suction port 11 so as to be slidable up and down. This blind plate 19 is slid up and down by a knob 20 and stopped at an arbitrary position. Thereby, the opening positions of the air suction ports 11 above and below the blind plate 19 can be selected. Therefore, the user can freely select the opening position of the air suction port 11 according to the position of the waste heat port of the OA equipment, or the position where the heat flow induced along the curtain 2 is most easily absorbed.

FIG. 5 shows yet another embodiment of a cylindrical fan unit according to the present invention. In this example as well, a cylindrical fan unit 1 having a prismatic shape (rectangular in cross section) is used, and an air suction port 11 is provided on the flat side of the fan unit. 22, and dampers 23 as shown in FIG. 6 are attached to a large number of small rectangular openings formed by this frame 22. In the example shown in Fig. 5, a total of 18 small openings are provided by the frame 22 (6 vertically and 3 horizontally), of which the top and bottom small openings remain open, and the second The damper 23 is attached to each small opening from the 5th stage to the 5th stage. In the state of use shown in FIG. 5, the second and fifth stage dampers 23a are in the closed state, and the third and fourth stage dampers 23b are in the open state. The damper 23, as shown in FIG.
It is a simple structure in which the central part of a rectangular wing 24 is supported by a shaft 25, and this shaft 25 is connected to the frame 2.
By supporting the blades 24 on the blades 24 and installing the blades 24 in such a manner that some friction is generated when the blades 24 rotate, the closed state and the open state can be arbitrarily adjusted and maintained. By selecting the mounting position of the damper 23 and adjusting the opening and closing of the mounted damper 23, the opening area and opening position of the air suction port 11 can be freely selected. Therefore, the strength of the suction flow and the suction position can be freely selected depending on the arrangement of the OA equipment and the site situation.

[Function and effect of the idea]

According to the OA equipment waste heat removal device of this invention,
The curtain 2 is stretched according to the arrangement of OA equipment and the working position of the operator.
The heat flow blocked by the fan unit 1 can be drawn to the cylindrical fan unit 1. At this time, the position where the winding rod 3 is erected can be freely selected, and the length of the curtain 2 can also be freely selected, so that the curtain 2 can be easily stretched in a manner most suitable for the situation at the site. Since the heat flow is guided along the curtain 2 to the cylindrical fan unit 1 and then to the ceiling surface, the heat flow is carried away from the operator, improving the working environment for the operator. There is no change in the heat load of the entire room. In particular, the waste heat removal device of the present invention has advantages over conventional devices in that it is easy to use and can be handled freely by the operator.
