Description

  The present invention relates to a fan part, and more particularly to a front cover of a fan.

  As shown in FIG. 6, the conventional electric fan 80 includes a motor 83 installed at an upper portion, a blade cover 82 installed on the front side of the motor 83, a position inside the blade cover 82, and the motor 83. And a blade 81 that is driven in combination. In use, the fan 80 can be blown by inserting the plug of the power cord of the fan 80 into an outlet, turning on the switch and turning on the power.

  However, in the fan cover of a conventional fan, the air blowing range cannot be narrowed, and air is blown wide radially, and furthermore, a cover member is provided at the front center of the blade cover, thereby obstructing air blowing. So there was a need to improve.

  The front cover of the electric fan according to the present invention has a main body in which a housing opening is formed at the center, and a plurality of spiral shapes that are fitted into the housing opening of the main body and extend outward from the center at intervals. And a spiral lid provided with a rib.

  The main body is provided so as to be connected to the mounting ring, a plurality of connecting ribs extending from the inner peripheral edge of the mounting ring toward the center at intervals, and the inner ends of the connecting ribs. It is preferable to provide a coupling ring.

  The spiral cover portion includes a cover portion formed in the center, the plurality of spiral ribs extending outward from the outer peripheral edge of the cover portion in a spiral shape at intervals, and the spiral ribs. It is preferable to provide an outer ring provided so as to be connected to the outer end of the outer ring.

  It is preferable that a plurality of engaging tabs that engage with the engaging ring of the main body protrude from the inner peripheral surface of the outer ring.

  As described above, the front cover of the electric fan according to the present invention can send wind in a tornado shape from the center of the front cover by the spiral rib of the spiral lid portion, and can widely blow air from the front cover by the connecting rib of the main body. In addition to enhancing the air blowing effect of the fan, there is also an effect of circulating indoor air.

It is a perspective view of the front cover of the electric fan which concerns on this invention. It is a front view of the front cover of the electric fan which concerns on this invention. It is a disassembled perspective view of the front cover of the electric fan which concerns on this invention. It is a partial side surface expanded sectional view of the front cover of the electric fan which concerns on this invention. It is a use condition figure when attaching the front cover of the electric fan concerning the present invention to an electric fan, and sending out wind. It is a perspective view of the conventional electric fan.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the following Example is only what showed the preferred embodiment of this invention, and the technical scope of this invention is not limited to the following Example itself at all.

  As shown in FIGS. 1 to 3, the front cover of the electric fan according to the present invention includes a main body 10 and a spiral lid portion 20, and the main body 10 includes an accommodation opening 11 formed in the center, A mounting ring 12 to be combined with the rear cover of the electric fan, a plurality of connecting ribs 13 extending from the inner peripheral edge of the mounting ring 12 toward the center at intervals, and the connecting ribs 13 And an engagement ring 14 provided so as to be connected to the inner end.

  As shown in FIGS. 3 and 4, the spiral lid portion 20 is fitted in the housing opening 11 of the main body 10 and provided at the center thereof, a cover member 21 for marking a manufacturer's logo mark, and the like, A plurality of spiral ribs 22 extending outward in a spiral shape from the outer peripheral edge of the cover portion 21 at intervals, and an outer ring provided so as to be connected to the outer ends of the spiral ribs 22 23. A plurality of engagement tabs 231 that are hook-like and engage with the engagement ring 14 of the main body 10 protrude from the inner peripheral surface of the outer ring 23 toward the rear side.

  Further, as shown in FIG. 4, as shown in another embodiment of the front cover of the electric fan according to the present invention, a fixing ring 15 connected to the outer ends of the plurality of connecting ribs 13 is provided, and can be attached and detached. The mounting ring 12 may be fitted and fixed to the ring ring 15.

  As shown in FIG. 5, when the front cover of the electric fan according to the present invention is attached to the electric fan A, a rear cover B is installed on the front side of the electric motor of the electric fan A, and the blades C interlocked with the motor in front of the rear cover B. Then, the front cover can be mounted on the electric fan A by combining the front cover on the front side of the rear cover B with the mounting ring 12.

  Also, when using the fan A, plug the power cord of the fan A into the outlet, turn on the power, and turn on the switch to drive the motor. Can be made. At this time, the air blow D passes through the spiral lid portion 20 to form a tornado shape with the spiral ribs 22, and can be sent widely toward the periphery of the front cover by the connecting ribs 13 of the main body 10. Therefore, if the front cover of the fan according to the present invention is used, the blower D from the fan A can be sent out in a powerful tornado shape, and the width of the blower D is widened, so that the blower effect of the fan A can be increased. It is possible to circulate indoor air as well as increase.

  As described above, the present invention can send out wind from the center of the front cover in a tornado shape by the spiral rib of the spiral lid portion, and can widely send out from the front cover by the connecting rib of the main body, so that the blowing effect of the electric fan is enhanced. And indoor air can be circulated.
