BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generator driven by a fan for radiating an outdoor unit of an air conditioner.

[0002]

2. Description of the Related Art Generally, air conditioners include a large-sized air conditioner for industrial or commercial use and a small air conditioner for home use called a so-called room air conditioner. An example will be described.

In general, an AC generator and a DC generator are provided as generators, and it is relatively easy to transmit and distribute AC electricity or electric power generated by the AC generator to a distant place. However, the only drawback of AC power is that it is difficult to store. In this regard, the DC electricity or power generated by the DC generator has various losses and is not suitable for power transmission and distribution to distant places, but is relatively easy to store.

SUMMARY OF THE INVENTION In view of the above, the present invention extends a rotating shaft of a heat-dissipating fan of an outdoor unit of a room air conditioner to the rear, and is provided with a DC generator to generate DC power. It is an object of the present invention to effectively store electricity and use it for various purposes.

[0005]

According to the present invention, a generator driven by a fan for radiating an outdoor unit of an air conditioner is used as a drive source. A rotating coil provided, a field magnet provided outside the rotating coil at a distance from the rotating coil, a commutator fixed to an extended rotating shaft of the outdoor unit heat dissipation fan, And a power take-out brush provided in contact with the child.

[0006]

As described above, according to the present invention, the DC power can be easily stored by providing the DC generator on the extended rotation shaft of the outdoor unit heat radiation fan of the air conditioner.
Therefore, the stored DC power can be used for various purposes.

[0007] By providing a storage device for storing the DC power taken out through the brush, the power generated can be used effectively.

Further, a DC-AC converter is provided between the output side of the battery and the input side of the air conditioner, and the AC output of the DC-AC converter is fed back to the air conditioner to control the air conditioner. The power requirements of the equipment can be significantly reduced.

[0009] Further, by providing a voltage regulator between the output side of the electric storage device and a desired load to be used, it is possible to remarkably widen the usage applications.

[0010] Further, the DC power of the battery can be used for various other purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a generator using a fan for radiating an outdoor unit of an air conditioner according to the present invention as a driving source will be described below with reference to the drawings. As shown in FIG. 1, a rotating shaft 2 of an outdoor unit heat radiating fan 1 of an air conditioner (not shown) is extended to an appropriate length in a leeward direction of the fan, and an end thereof is rotatable on a shaft support 3. After being mounted, the rotor coil 4 is fixed to the extended rotary shaft 2 as shown in the figure.

Further, a commutator 5 is fixed to the rotor shaft 2 behind the rotor coil 4 at a slight distance from the rotor coil 4. The commutator 5 is also formed in such a state that a large number of conductive commutator pieces are fixed in parallel in the axial direction.

The rotor coil 4 is formed by winding a large number of coils around a cylindrical bobbin in the axial direction. Therefore, a large number of coil ends are connected to the commutator pieces respectively.

A stator field 6 made of a permanent magnet is provided outside the rotor coil 4 as shown in FIG. Further, a pair of brushes 7 are provided on both sides of the commutator 5 so as to be freely contactable, and the brushes 7 are connected to a battery 9 via a conductor 8.

In the generator having the outdoor unit radiating fan of the air conditioner of the present invention configured as described above, first, the air conditioner is turned on and the air conditioner is operated to start cooling or heating. At the same time, the outdoor unit heat-dissipating fan rotates, and this rotation causes the rotor coil of the generator to rotate, generating electromotive force in this coil and starting power generation.

The generated power is taken out of the commutator 5 by the brush 7 and stored in the battery 9 via the conductor 8.

In the present invention, the generator is installed on the leeward side of the fan for radiating the outdoor unit. If the generator is installed on the windward side of the fan, the hot air accelerates the deterioration of the generator and shortens the life. Because.

The DC power thus stored can be used for various purposes. For example, its main use is as auxiliary power for air conditioners. In this case,
It is necessary to provide a DC-AC converter (not shown) between the input side of the air conditioner and the output side of the battery 9.

Further, for example, the output side of the battery;
By providing the voltage regulator between the desired utilization load, the utilization application can be significantly expanded. For example, a car battery can be charged as needed.

The present invention is not limited to the above-described example, and various modifications and changes can be made without changing the gist. For example, in the present invention, the stator is a field magnet, Although the stator is a coil, the stator can be a coil and the rotor can be a field magnet.

Further, in the present invention, a DC generator is used as a generator utilizing a fan for radiating an outdoor unit of an air conditioner. However, an AC generator can be used instead. In this case, since the output of the generator is AC power, it is necessary to provide a rectifier between the brush and the battery to convert the AC power to DC power.

Although the present invention has been described with particular reference to a small-sized air conditioner for home use, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a large air conditioner for industrial or commercial use.

[0023]

As described above, according to the present invention, electric power is generated in-house by effectively utilizing a fan for radiating an outdoor unit of an air conditioner as rotational power of a generator, and this power is fed back as auxiliary power. As a result, it is clear that the power required for the air conditioning equipment taken from the mains power supply, particularly for the room air conditioner, can be greatly reduced, and the economical effect is obviously increased.
