Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a partition panel incorporating a blower fan.

[0002]

[Prior Art]

 In recent years, an intake port and an exhaust port have been provided on the side of a partition panel that partitions a room such as an office into small rooms, or a so-called low partition (hereinafter collectively referred to as partition panel) that partitions desks from each other. A blower fan is installed in the hollow part inside the partition panel that connects both ports to form an air flow in the space partitioned by the partition panel to prevent air from staying in the space. Therefore, it is known to enhance the air conditioning effect in the room.

[0003]

[Problems to be solved by the device]

 In offices, etc., it is often the case that a desk is placed close to the partition panel as described above, and various electronic devices are placed on the desk for use.In such a case, it is installed in the partition panel. Magnetic leakage from the motor for driving the fan for blowing air may cause image defects such as flicker and noise in electronic devices, especially in display devices using cathode ray tubes.

In view of the above-mentioned problems of the conventional technique, the present invention shuts off the magnetic leakage from the fan driving motor built into the partition panel and arranges the electronic device in the vicinity of the partition panel. The purpose is to prevent magnetic interference to the.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is characterized in that, in a partition panel in which a blower fan is incorporated in a hollow portion, at least the side surface of the motor for rotating the fan is covered by a magnetic shield cover. I am trying.

[0006]

[Action]

 By covering at least the side of the fan driving motor on the panel side with the magnetic shield cover, magnetic leakage from the motor is blocked by the magnetic shield cover, and it does not leak outward from the panel surface. Even if the electronic devices are arranged close to the partition panel, magnetic interference will not occur in them.

【Example】

 The drawings show an embodiment of the present invention, in which a display device (3) using a cathode ray tube (3a) and other electronic devices are mounted on a table (2) surrounded by a hollow plate-shaped partition panel (1). A device (not shown) is placed (see FIG. 3).

An intake port (5) and an exhaust port (6) equipped with louvers (4) are provided on the panel surfaces (1a) of the partition panel (1) shown in FIG. Has been. In the hollow part (1b) of the partition panel (1) that communicates the intake port (5) and the exhaust port (6), a part of the partition (1) that is almost level with the intake port (5) is A cross-flow type fan (7) that blows the sucked air downward with an exhaust port (6) is supported by a pair of support plates (8) that are horizontally installed in the hollow part (1b). It is rotatably arranged.

(9) is a motor for driving the fan (7) supported by one of the support plates (8). In this motor (9), the vertical shield plate (10) and the upper and lower edges (11a) of the shield plate (11) bent in a substantially U shape are overlapped with each other, and the set panel (12) is used for the partition panel. (1) The magnetic shield cover (13), which is fixed to one inner surface of one side and has a substantially rectangular tube shape, surrounds both side surfaces and the upper and lower surfaces on the panel surface (1a) side.

An air guide plate (11b) that slopes upward immediately below the fan (7) is continuously provided at one side edge of the lower side of the shield plate (11). The shield plates (10) and (11) are preferably made of, for example, a high-permeability cobalt amorphous alloy flake fixed in a sandwich with a plastic film, or a simple iron plate.

According to this embodiment, when the fan (7) is rotated by the motor (9), the air sucked from the intake port (5) as shown by the arrow, the air in the hollow part of the partition panel (1). It flows downward through (1ba) and is discharged to the outside through the exhaust port (6), thereby forming an air flow in the space partitioned by the partition panel (1) and performing ventilation. The hot air generated by the display device (3) and the like can be discharged to the outside from the space.

During operation of the motor (9), harmful magnetism leaking from the motor (9) is blocked by the cylindrical magnetic shield cover (13), and is prevented from leaking from the panel surface (1a). Even if the electronic device such as the display device (3) is arranged in the vicinity of the partition panel (1), image troubles such as flicker and noise will not occur.

Further, a part of the air sucked from the intake port (5) by the fan (7) is introduced into the cylindrical magnetic shield cover (13) by the baffle plate (11b) and passes therethrough, Since the motor (9) is cooled, overheating of the motor (9) can be prevented.

The baffle plate (11b) may be omitted if necessary. Further, the magnetic shield cover (13) is not limited to the cylindrical one as described above, but is, for example, a plate-like one attached to the inner surface of the partition panel (1) facing the motor (9). Alternatively, the magnetic shield cover (13) may be formed as a part of a component member such as a side plate of the partition panel (1).

Further, as shown by an imaginary line in FIG. 3, an appropriate cooling / heating means (14) is provided in the hollow portion (1b) of the partition panel (1), and air flowing in the hollow portion (1b) is provided. May be cooled or heated to have a cooling / heating function. In this case, the motor (9) is preferably a reversible type that can rotate the fan (7) forward and backward.

[0016]

[Effect of the device]

 According to the present invention, the magnetic shield cover that covers the motor blocks the leakage magnetism from the motor, so that even if the electronic device is placed close to the partition panel, magnetic interference such as noise or a flicker does not occur. It is very convenient because each member of electronic equipment can be freely arranged.

Further, if the air guide plate is provided and a part of the intake air is introduced into the cylindrical magnetic shield cover, overheating of the motor can be prevented and durability can be improved.
