On the other hand, as shown in Figure 4, the pedestal 50 is provided with a plurality of control switches. First, there is provided a function selection switch 52 that can select a whirlwind function and a warm air function. Therefore, when the function selection switch 52 is set to 'fan', power is not applied to the heater 100. On the contrary, when the function selection switch 52 is set to 'hot air', power is applied to the heater 100.

On the right side of the function selection switch 52, a time setting switch 54 is provided. The time setting switch 54 is provided to set the operation time of the continuous and about 180 minutes, the function and operation principle of this time setting switch 54 is a general known technique, so the detailed description thereof will be omitted here.

Although not shown in detail, the pedestal 50 further includes a resistor (not shown) and is connected to the warm air side of the function selection switch 52. Accordingly, when the function selection switch 52 is selected, power applied from the outside flows through the resistor (not shown), so that the rotation speed of the rotary blade 94 is relatively higher than that of the 'wind'. Will be slow.

More preferably, the rotational speed of the rotary blade 94 is reduced to about 1/10 compared to the case of 'hot air' in the case of 'warm wind'. In other words, even when the same 'breeze' is set, the amount of wind generated from the fan is about 1/10 in the case of the 'hot air' function compared to the case of the 'fan wind' function.

As such, the reason for reducing the rotation speed of the rotary blade 94 in the case of 'hot air' is to allow sufficient heat to be transmitted to the user. That is, in the case of acting as a hot air fan, the rotary blade 94 does not need to rotate at a high speed. If the air speed is high, the result is that the human body is cooled, so that the user does not feel warm.

Hereinafter, the operation of the hot air combined use fan having the configuration as described above.

In the above configuration, the case of using the electric fan as in the prior art in the summer will be described. At this time, the heater 100 is separated and the combined hot air fan according to the present invention will have a configuration similar to that of the conventional fan.

Therefore, the user places the function selection switch 52 of the pedestal 50 to the 'wind' position to operate the operation button 56. In this case, the rotary blade 94 is rotated by the power applied from the outside to blow air forward.

Next, when warm air is required, such as winter, the heater 100 is attached. In this case, first, the rear protection net 90 and the front protection net 120 are separated, and then the heater 100 is brought into close contact with the front protection net 120 so as to fasten the heater 100 to the front protection net by the fastening screw 108. 120).

Then, the front protection net 120 is mounted to the rear protection net 90 by the fastening rib 124 and the fastening lever 122. Since the process of mounting the front protection net 120 to the rear protection net 90 by the fastening rib 124 and the fastening lever 122 is applied to a fan generally used in recent years, a detailed description thereof will be omitted.

When the heater 100 is mounted, the user places the function selection switch 52 in the 'hot air' position, and then operates the combined hot air fan using the operation button 56. In this case, the rotary blade 94 rotates by the force of the motor 70 to send air forward. At this time, the air sent to the front heat exchange occurs in the heater 100 becomes hot air.

As described above, the rotation speed of the rotary blade 94 varies according to whether the heater 100 is operated. That is, when the function selection switch 52 is set to 'hot air' so that the heater 100 is operated, the rotational speed of the motor 70 is set to 'vehicle' so that the heater 100 is not operated. It is reduced to about 1/10 compared to the case. Therefore, the rotation speed of the rotary blade 94 is reduced to about 1/10.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, as shown in FIG. 5, a plurality of heating wires 102 may be provided in the heater 100, and these heating wires may be configured to be individually turned on / off.

Looking in more detail, as shown in Figure 5, the central portion is provided with a first heating wire 102a, the left and right of the first heating wire (102a) is provided with a second heating wire (102b) and a third heating wire (102c), respectively. do. Of course, even at this time, the heater 100 is preferably formed so that the heating wire is not formed at the central portion of the first heating wire 102a so that the heater 100 is formed at a position corresponding to the rotation range of the rotary blade 94, and has a zigzag shape. A constant gap is formed between the heating wires 102 to allow the flow of air.

And the outer side of the plurality of hot wire 102 is formed a circular heater frame 104 corresponding to the edge of the rotary blade 94, as in the above embodiment, the upper and lower parts of such a heater frame 104 A support guide 104 ′ is further formed on the side to support the plurality of hot wires 102.

The plurality of hot wires 102 are individually turned on / off. In more detail, the plurality of hot wires 102 are selectively turned on / off in conjunction with a change in rotation speed of the rotary blade 94. That is, the quantity of the plurality of hot wires 102 turned on increases and decreases as the rotation speed of the rotary blade 94 increases or decreases.

For example, when the user presses the breeze button 56b of the operation button 56, power is applied only to the first heating wire 102a so that the first heating wire 102a is heated. When the user presses the weak wind button 56c among the operation buttons 56, power is applied to the first heating wire 102a and the second heating wire 102b, respectively, so that the first heating wire 102a and the second heating wire ( 102b) is heated simultaneously. Therefore, heat generation is relatively increased compared to the case where only the first heating wire 102a is heated.

On the other hand, when the user presses the strong wind button 56d of the operation button 56, power is applied to both the first heating wire 102a, the second heating wire 102b, and the third heating wire 102c so that the first heating wire ( 102a, the 2nd heating wire 102b, and the 3rd heating wire 102c heat simultaneously. Therefore, at this time, the heat generated from the heater 100 is the most compared to the 'breeze' or 'wet air'.

In addition, the above-mentioned warm air combined electric fan can also have a structure as shown in FIG.

That is, in the above embodiment, the heater 100 is configured to be detachably installed on the front protection net 120, but as shown in FIG. 6, the heater 100 is integrally fixed to the front protection net 120. It may also be provided with a front heater protection net (130) separately. Of course, at this time, as shown, one end of the heater 100 is connected to the heater power cord 110 to which power is applied from the outside, and one end of the heater power cord 110 is connected to the heater plug 112. Is provided.

Therefore, in the case of using the fan as in the above embodiment, the heater 100 is separated from the front protection net 120, and in the case of having a warm air function, the heater 100 is integrally attached to the front heater The protection net 130 is mounted on the rear protection net 90 and used.

As described above, according to the present invention, since the heater is added in the conventional fan configuration, it serves as a hot air fan in winter. Therefore, since a single product has two functions (a fan and a hot air fan), there is an advantage of reducing the overall purchase cost of the product.

In addition, in the hot air combined electric fan of the present invention, a plurality of adjustable heating wires are provided in the heater. Therefore, the number of heaters turned on / off varies according to the user's setting. Therefore, it is possible to adjust the blowing amount of the warm wind has the advantage of more convenient use.

In the present invention, the amount of air blown is reduced to about 1/10 in the case of the 'hot air' function compared to the 'hot air' function. Therefore, since the heat generated from the heater is transmitted to the user by the weak wind, there is an effect of doubling the haptic temperature that the user feels.
