Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a drive motor device with a filter suitable for heat dissipation of an electronic device storage control panel.

[Prior Art] In recent years, automation and labor saving have progressed in cotton (cotton yarn, cotton cloth) factories, wood factories, noodle factories, etc., and many electronic measuring instruments and control devices have been used. In order to ensure reliability, safety, etc. of such electronic devices, it is necessary to always maintain the internal temperature of the storage box for storing those electronic devices at an appropriate value. A drive motor device with a filter is provided. FIG. 6 shows a conventional example of such a drive motor device with a filter. Reference numeral 1 is a drive motor, 3 is a blade attached to the outer end of an output shaft 2 of the drive motor device, and the drive motor device 4 with a filter is constituted by these. I am configuring. Reference numeral 5 is a filter disposed in front of the drive motor device with a filter 4 so as to close the suction port 6.

[Problems to be Solved by the Invention] However, in such a conventional drive motor device with a filter 4, cotton dust, dust, etc. 7 adhere to the filter 5 to cause clogging, or adhere to the blades 3. There is a problem that the heat exchange capacity of the drive motor unit with a filter 4 is significantly reduced. Therefore, frequent maintenance is required, and by the way, the above-mentioned factory requires maintenance of the filter 5 once a week.

Therefore, the present invention has been made in view of the conventional problems as described above, and the purpose thereof is to improve the durability of the filter by forcibly removing cotton dust and the like adhering to the filter, and reduce the number of maintenances. It is an object of the present invention to provide a drive motor device with a filter capable of reducing the number.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a drive motor, a blade attached to an output shaft of the drive motor, and a filter arranged in front of the blade, This filter is rotated by the drive motor or another drive motor.

[Operation] In the present invention, the filter is rotated by the drive motor to scatter and remove cotton dust, cotton dust and the like adhering to the filter by centrifugal force.

[Examples] Hereinafter, the present invention will be described in detail based on Examples shown in the drawings.

FIG. 1 is a side view showing the first embodiment when the drive motor unit with a filter according to the present invention is used as a suction type radiator, and FIG. 2 is a rear view. In the figure, the same components and parts as those in FIG. 6 are designated by the same reference numerals, and the description thereof is omitted. In these drawings, in the present embodiment, the filter 5 which is conventionally fixed to the suction port 6 is fixed to the center of the front surface of the blade 3, and the blade 3 and the filter 5 are integrally rotated by the output shaft 2. Is. The filter 5 is formed in a disc shape and is held by a holding frame 10 to prevent deformation.

In such a structure, when the thickness or amount of the cotton dust 7 attached to the surface of the filter 5 becomes a certain amount (determined by the rotation speed of the motor and the weight of the cotton dust 7),
It cannot withstand the centrifugal force and is scattered and removed from the surface of the filter 5 in the tangential direction thereof.

That is, the present invention rotates the filter 5 and forcibly removes the cotton dust 7 and the like adhering to the filter 5 by the centrifugal force. As a result, the clogging of the filter 5 is extremely small, and the number of times of maintenance can be reduced. Further, if the clogging is small, the life of the filter 5 can be extended and the heat exchange capacity of the radiator can be stably maintained.

FIGS. 3A and 3B are side views showing the second embodiment of the present invention. In this embodiment, the shape of the filter 5 is changed. In the figure, (a) is formed in a conical shape so that the apex protrudes in front of the drive motor 1, and (b) in FIG. The curved surface is formed so that the opposite surface has a convex curved surface.

In the first embodiment, since the filter 5 is formed in a flat plate shape, the cotton dust 7 and the like adhering to the surface of the filter is scattered while moving in the outer peripheral direction along the surface of the filter 5 for removing scattering. On the other hand, in the present embodiment, since the surface of the filter 5 is inclined with respect to the output shaft 2 in the present embodiment, cotton dust 7 and the like can be quickly scattered and removed from the filter surface. Have

FIG. 4 is a side view showing the third embodiment of the present invention. In this embodiment, the brush 12 is arranged close to the opposite surface of the filter 5 having the structure shown in FIG. 3 (a), and when the thickness of cotton dust 7 reaches a certain thickness, it is scraped off by the brush 12. It is a thing.

Since the cotton dust 7 containing oil sticks to the filter 5, it is difficult to scatter and remove it only by the centrifugal force. On the other hand, when the brush 12 is provided as in the present embodiment, such dust dust 7 is generated. Also has the advantage that it can be removed satisfactorily.

FIG. 5 is a side view showing the fourth embodiment of the present invention. In this embodiment, the filter 5 is rotated by a filter motor 13 provided separately from the drive motor 1 for driving the blades 3. The rotation of the output shaft 14 of the motor 13 is
It is transmitted to the filter 5 by the 15 and the pulleys 16a and 16b. However, the rotation transmission means is not limited to the belt 15, and a gear may be used.

In addition, in each of the above-described embodiments, the case where the drive motor device with a filter is used as the suction radiator is explained.
The present invention is not limited to this, and it is needless to say that the present invention may be used as an exhaust type radiator in which the wind flow is in the opposite direction to the above embodiment. In that case, if the filter shape is as shown in FIG. 3 (a) or (b), it may be attached to the blade 3 or the drive motor 13 (FIG. 5) with the front and back reversed.

[Advantages of the Invention] As described above, in the drive motor device with a filter according to the present invention, the filter arranged in front of the blades is rotated by the drive motor. Can be effectively removed by scattering. Therefore, it is possible to reduce the clogging of the filter and prolong the service life thereof, and it is possible to reduce the number of times of the maintenance work of the filter and the blade. Further, if the clogging is small, the effect is large such as maintaining a good heat exchange capacity.
