Fan Assembly Possible Operation Situation Confirmation "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fan assembly capable of confirming an operating state, and more particularly, it is possible to easily confirm from outside whether a fan installed in a distribution board or an electric switchboard is operating.

Generally, the distribution panel or the switchboard is provided with an air intake fan for drawing air and an air discharge fan for discharging air.

In the case where it is not necessary to operate among a large number of fans installed in a distribution board (or an electric distribution board), when the fan recognizes a line that is in a stopped state, there is a closed end in which the fan continues to operate.

Such a fan is installed at a predetermined position of the enclosure of the distribution panel. For example, in the case of an exhaust fan, it is difficult to easily check whether the fan is operating outside the distribution panel.

In other words, a vent hole is formed at a position where the fan is positioned to suck or discharge air. Since a fan is provided inside the vent hole, it is difficult to easily check whether the fan inside the fan is operating due to the vent hole.

Of course, a worker (or a manager) can approach the ventilation hole and feel his / her flow state by touching his / her hand, etc., or the operation sound of the fan may be generated during the operation of the fan, In the case of the exhaust fan, the ventilation hole is located at the upper part of the distribution board, so that it is not easy for the user to stand in the hand, and the operation sound of the fan is often not heard due to the surrounding noise or the like.

Therefore, if there are many distribution boards (or switchboards) installed in the industrial field, it is not possible to easily know whether the fan installed in each distribution board is in operation, so that a sticker or the like can be attached to know whether or not the fan is in operation. , So the maintenance was inconvenient.

Accordingly, light is emitted to the outside from the upper portion of the ventilation hole 20 into which the LED 34 is inserted, so that the driving fan 50 can be easily recognized.

On the other hand, when the drive fan 50 is stopped, since the air is not discharged, the driven fan 40 also stops rotating, so that the power generation operation of the motor 43 does not occur and the LED 34 does not emit light As a result, the light of the LED 34 is not emitted. Therefore, it can be visually confirmed from the outside of the distribution panel 10 that the driving fan 50 is in a stopped state.

[ 2nd implementation  Yes]

FIG. 5 is an installation view of a fan assembly according to a second embodiment of the present invention, and FIG. 6 is an exploded perspective view of a fan assembly according to a second embodiment of the present invention.

1, the fan assembly 2 according to the second embodiment of the present invention is installed at a predetermined position or upper portion of the distribution board 10 as shown in FIG. 1, A case 30 accommodated in the ventilation hole 20 and a driven fan 40 and a driving fan 50 sequentially disposed inside the case 30.

In the second embodiment, the driven fan 40 is relatively larger than the driven fan 40 in the above-described first embodiment, and is disposed substantially in parallel to the front of the driving fan 50. [

An operation member 60 is coupled to a lower portion of the driven fan 40 to rotate the driven fan 40 in accordance with the rotation of the driven fan 40.

6, the central portion 41 of the driven fan 40 is rotatably coupled at the center of the ventilation opening 20. The center portion 41 of the driven fan 40 is rotatably coupled to the ventilation opening 20 in the horizontal direction So that the center portion 41 of the driven fan 40 is rotatably engaged with and supported by the engaging member 21,

 One end of a blade 42 positioned at a lower portion of the central portion 41 of one of the plurality of blades 42 provided along the outer peripheral surface of the central portion 41 of the driven fan 40 The operation member 60 is engaged and engaged.

The operation member 60 may be coupled to an end portion of the blade 42 located at the upper portion of the central portion 41 to indicate whether the drive fan 50 is operating at an upper portion of the ventilation hole 20. [

5 and 6, a returning elastic member 44 (for example, a torsion spring) is mounted on the center portion 41 of the driven fan 40 so as to be rotated by the operation of the driving fan 50 When the driving fan 50 stops again after the driven fan 40 rotates at a predetermined angle, the driven fan 40 in the rotated state is returned to its original position.

One end of the elastic member 44 is fixed to the ventilation hole 20 and the other end of the elastic member 44 is fixed to the center portion 41 of the driven fan 40.

In addition, the driving fan 50 includes a motor (not shown) so that the driving fan 50 can be rotated when electric power is applied thereto as in the first embodiment. In an embodiment of the present invention, the driving fan 50 is described as an exhaust fan as an example. However, the present invention is not limited thereto, but may be applied to an intake fan as well as an exhaust fan.

The operating member 60 includes a connecting piece 61 coupled to an end of the blade 42 of the driven fan 40 and a display window 60 coupled to an end of the connecting piece 61 and provided at a lower portion of the ventilation hole 20. [ And a display member (62) for displaying a statement indicating whether or not the fan is operated to the outside through a door (22).

For example, the display member 62 may include a phrase "ON" and "OFF ".

The operation member 60 is horizontally moved at the lower end of the ventilation hole 20 so that a horizontal groove is formed on the inner surface of the lower end of the ventilation hole 20 so that the display member 62 of the operation member 60, The display member 62 can not move any more at the end of the horizontal groove and is caught by the driven fan 40 even if the corresponding blade 42 of the driven fan 40 continues to rotate, Can not rotate any more and remains in a slightly rotated state.

On the other hand, when the driving fan 50 is stopped and the rotation of the driven fan 40 is stopped at the same time, the returning elastic member 44 causes the reverse rotation of the driven fan 40, The display member 62 of the operating member 60 is horizontally moved to stop at the end opposite to the horizontal groove of the ventilation opening 20 and stops, The rotation return operation is stopped.

9A, since the direction of flow of the air by the driving fan 50 is opposite to that of the case of the exhaust fan, when the suction fan is to be used for the suction fan, A separate swivel plate is formed on the lower portion of the hinge portion 72 of the hinge portion 71 so that when the air is sucked and flowed from the left to the right in the drawing and the separate swivel plate is pushed from left to right, The rotary plate 71 formed on the upper portion of the display member 72 moves from right to left so that the pressing member 73 enters the lower end of the display member 36 to be lifted.

In other words, in the case of an intake fan, a separate swing plate may be configured to move in opposite directions about the swing plate 71 and the hinge portion 72 like a seesaw.

As shown in FIG. 6, when the fan is driven by electricity, the fan assembly 1 having such a structure according to an embodiment of the present invention can rotate the drive fan 50, The driven fan 40 provided at the front of the driving fan 50 is rotated by the air discharged to the outside.

The rotation of the driven fan 40 does not rotate 360 degrees, but only slightly rotates at a predetermined angle. That is, the angle range is such that the display member 62 alternately displays "ON" or "OFF" from the display window 22 of the ventilation opening 20.

At this time, the connecting piece 61 of the actuating member 60 connected to the end of one of the blades 42 of the driven fan 40 is simultaneously moved. As shown in FIGS. 7A and 7B, The display member 62 coupled to the display unit 61 horizontally moves in one direction and enters the inside of the display window 22 provided at the lower portion of the ventilation opening 20 to display the phrase "ON" through the display window 22, It can be seen that the fan is operating.

7A and 7B show only the display window 22 formed under the ventilation opening 20 for convenience.

When the driving fan 50 is continuously rotating, the air is continuously discharged to the outside through the ventilation opening 20. The driven fan 40, which is slightly rotated in one direction, The member 44 tends to return to its original position. However, the air is continuously discharged and the elastic force of the returning elastic member 44 is overcome by the fluid force of the air, Ensure that the position is maintained.

On the other hand, when the drive fan 50 is stopped, no air flows, and the driven fan 40, which has been rotating, is reversely rotated to the original position by the returning force of the returning elastic member 44 do.

The connection piece 61 of the operation member 60 connected to the driven fan 40 is moved in the direction opposite to the operation of the drive fan 50 and the display member 62 is moved from the display window 22 By this deviation, the word "OFF" is displayed on the display window 22 instead of disappearing of the indication "ON" in the display window 22, so that it is easy to see that the fan is stopped visually.
