On the other hand, the outdoor unit periodically repeats the ON / OFF operation according to the temperature of the area to be cooled, so that damage to the equipment due to ground fault, ON / OFF The service life of the motor is comparatively short due to frequent faults due to grounding of the motor windings or damage to the motor bearings due to changes in the operating environment.

Therefore, the motor that has failed is discarded and replaced with a new electric motor. In this case, the fan blade assembled in the motor to be discarded is reused without being discarded. In order to reuse the fan wings, there is a disadvantage that the disassembly operation must be carefully performed. Therefore, when it is difficult to separate the fan blades, a gear plug and a gas torch are used. However, there is a problem that it is difficult to separate the fan blades by pulling the fan blades from the motor due to the force of the tool.

Further, when the fan blade is disassembled for reuse, if the fan blade is damaged or deformed, it may adversely affect the stable operation of the motor. If the detached fan blade is severely damaged or deformed, the fan blade needs to be separately purchased, thus increasing the cost.

In order to fully understand the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, the detailed description of the known functions and configurations that are considered to be unnecessarily blurring the gist of the present invention is omitted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings, and the motor fan blade separation assistance frame of the present invention will be described in detail.

As shown in FIGS. 2 to 6, the motor fan fan blade separating assistance frame 2 of the outdoor unit according to the present invention is formed such that the electric motor M of the cooling fan is housed while exposing the fan blade F to the upper surface A separating mounting hole 4 formed in a double head so as to be roughened by exposing a fan blade F to an upper surface of the case C; A latch set 8 having a male and female structure provided on the front separation line L to lock or unlock the case C when the case C is opened or closed, A pair of torsion preventing grooves 10 and a torsion preventing protrusion 12 which are engaged with the surfaces of the cases C abutting each other and between the latch sets 8, (C) on one side to float on the floor and to facilitate the movement of the place on both sides And a plurality of casters 16 each having a lock lever 14 installed thereon.

The latch set 8 includes a latch hook 18 provided in the first case C1 and a latch hook 18 provided in the second case C2 for locking the ring 20 to the latch hook 18. [ And a lever (22).

The torsion preventing groove 10 and the back stopper protrusion 12 are formed on the front and rear surfaces of the first and second cases C1 and C2, respectively. That is, the torsion preventing grooves 10 are formed on the front surface of the first case C1 and the rear surface of the second case C2, respectively. The torsion preventing protrusion 12 is formed on the rear surface of the first case C1 and on the front surface of the second case C2.

In addition, the separation help frame 2 is formed in a symmetrical structure that is opened or closed on both sides along a separation line L which is divided vertically and formed along the separation line L formed vertically.

In addition, the separation assisting frame 2 is formed in a rectangular parallelepiped shape, and a bottom portion forming the lower surface is omitted. Therefore, the bottom portion, which is the lower surface, is omitted, so that the electric motor M falling down upon separation of the fan blade F does not directly collide with the separation assistance frame 2. [ That is, the durability of the main body auxiliary frame 2 is maintained.

The separating aid frame 2 has a double-thickness upper surface on which the separating mounting hole 4 is formed so as to withstand the rotation of the rotating shaft S of the electric motor M. By forming the upper surface to have a double thickness, it is possible to separate the fan blades F from the shocks received during the hitting.

In addition, the separation assisting frame 2 prevents the operator from being hurt when separating the fan blade F from the electric motor M by chamfering each corner corner.

Hereinafter, an example of using the motor fan blade separating assistance frame of the outdoor unit as described above will be described.

When repairing an outdated outdoor unit of an air conditioner installed in an industrial site or a building, the electric motor M and the fan wing F are separated. In other words, since the rotary shaft (S) of the electric motor (M) is a part to be discarded and the fan blade (F) is a reusable part, it must be separated without damaging it. Accordingly, it is necessary to stably fix the fan blade F so that only the rotation axis S of the electric motor M can be hit. Therefore, when separating the fan blade F from the rotary shaft S of the electric motor M, the separation assistance frame 2 is used to prevent the fan blade F from being damaged or deformed.

First, the separating aid frame 2 is moved by using the casters 16. When the separation aid frame 2 is ready, loosen the front latch sets 8. That is, the latch lever 22 is lifted so as to be positioned on the center line, the ring 20 engaged with the latch hook 18 is loosened, and then the lock is loosened.

After releasing the latch sets 8, the first case C1 and the second case C2, which form the case C, are opened on both sides. When the case C is opened, the hinges 6 provided on the back surface of the case C are axially opened.

The reason why the case C can be opened is that the first and second cases C1 and C2 are bisected by the separation line L. [ After the case C is opened, the fan wing F is put on the detachment mounting hole 4 of the half case case C, and the electric motor M below the fan wing F is inserted into the storage space R.

Then, the facing case C is closed so that the first and second cases C1 and C2 are engaged. The engagement of the first and second cases C1 and C2 also causes a pair of anti-torsion grooves 10 and anti-torsion protrusions 12 formed on the front and rear separation lines L to be engaged.

When the case C is engaged, the ring 20 of the front latch set 8 is hooked on the latch hook 18, and then the latch lever 22 is turned so that the case C is firmly engaged. When the case C is engaged, the lock lever 14 provided on the casters 16 on both sides of the case C is operated to fix the casters 16 so as not to roll.

When the caster 16 is fixed, the worker separates the fan blade F exposed through the detachment mounting hole 4 on the upper surface of the case C from the electric motor M. That is, it hits the rotation axis S of the electric motor M exposed at the center of the fan blade F with a hammer or a hammer.

The motor rotation axis S is detached downward toward the storage space portion R because the motor rotation axis S is struck with the fan wing F mounted on the separation mounting hole 4. And the separating mounting hole 4 formed on the top face of the double middle head strikes the fan blade F when striking the motor rotation axis S.

The impact of the case C upon impact is such that the latch set 8 and the hinge 6 provided on the case C separation line L are resistant to impact. Since the pair of warpage preventing grooves 10 formed on the front and rear separation lines L and the warp preventing projections 12 are tightly coupled to each other, the case C is firmly held .

The fan blade F is separated through the blow against the motor rotation axis S described above. The electric motor M from which the fan blade F is separated falls on the bottom of the housing space R of the case C. When the fan blade F is detached, the electric motor M is removed from the case space C by operating the latch levers 22, and then the electric motor M for separating the fan blade F from the housing space M R), and the case (C) is joined and separated.

Since the separation assistance frame 2 is used when the fan wing F is separated from the electric motor M, the fan wing F can be easily disassembled without being damaged or deformed. The fan blade F separated through the above-described process can be recycled.

The corners of the case C are chamfered by the corners of the case C to prevent the operator from being exposed to a safety accident when the fan wing F is separated from the electric motor M. [

As described above, the embodiment of the motor fan-wing separating assist motor of the present invention is merely illustrative, and various modifications and equivalent other embodiments can be made by those skilled in the art. You can see that it is. Therefore, it is to be understood that the present invention is not limited to the form described in the foregoing description. Accordingly, the true scope of protection of the present invention should be determined by the technical idea of the appended claims. It is to be understood that the appended claims are intended to cover all such modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
