BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fan combined with an electric fan, and more particularly, to a fan combined with an electric fan that operates in a fan mode or a hot air mode to generate cold air or hot air.

Generally, an electric fan is connected to a rotary motor so as to blow the flow of wind generated by a rotating fan blade in a specific direction, thereby providing a coolness to the user. These fans are mostly used only during the summer season, and are stored in the warehouse during the non-summer season.

On the other hand, the hot air is used mainly for winter, as opposed to the fan, and is used for indoor heating. BACKGROUND ART [0002] In recent years, hot air fans in the form of an electric fan have been widely used. Such hot air fans are provided with circular heat reflecting plates and heat generating elements for radiating heat to the inside. To be diverted. These hot winds are also kept in the warehouse during the winter season.

Since the fan and the fan have different functions and do not commonly use the fan, the user needs to install the fan and the fan, respectively.

Also, in the season when both fan and hot air are not used, such as spring or autumn, fans and heat fans must be stored in the warehouse, which causes additional problems that take up a lot of space.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a combined fan for a fan that allows an electric fan to function as a fan.

According to an aspect of the present invention, there is provided an air conditioner, comprising: a fan that operates in an electric fan mode and a hot air fan mode, wherein the fan rotates in one direction when operated in the fan mode, A front cover disposed in a front direction of the fan, and a rear cover disposed in a rear direction of the fan, the rear cover disposed between the fan and the rear cover, And a control unit.

The rear cover may be partially opened in the fan mode and closed in the hot air mode.

The rear cover is realized in the form of a double lid, and a part of the surface is opened and closed by rotating the inner lid in the left / right direction.

And the rear cover is automatically opened or closed by the driving force of the driving motor when the operation mode is switched.

And the rear cover is automatically opened and closed by an opening / closing operation of the opening / closing means connected to the inner cover when the operation mode is switched.

And the rear cover is opened and closed by a manual operation of the handle provided on the inner cover when the operation mode is switched.

The inner surface of the rear cover is formed of a material having a high reflectivity.

In the meantime, the combined fan for a fan according to the present invention further includes a control unit for controlling the operation mode of the hot air. At this time, the control unit may include a switching unit for switching an operation mode of the hot air winders according to an input signal from a mode selection switch or a remote controller at a remote location, and a control unit for generating a control signal corresponding to the operation mode by switching the operation mode of the switching unit And a control unit for controlling the operation of the driving motor.

According to the present invention, not only the function of the fan but also the function of the fan can be achieved by using only one fan, so that the fan and the fan are not required to be provided. Therefore, the cost is reduced and the space utilization due to the storage of the fan or the fan is increased. .

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a view showing a configuration of a combined heat and air fan according to the present invention. Referring to FIG. 1, the combined fan according to the present invention includes a fan 10, a driving motor 20, a front cover 30, a rear cover, and a heating wire 50.

The fan 10 is coupled to the driving shaft 15 of the driving motor 20. The fan 10 rotates together with the driving shaft 15 when the driving motor 20 is turned on to generate wind, The drive motor 20 rotates the drive shaft 15 in one direction or the other direction by a control signal output from the control unit 120 according to the operation mode of the fan.

The front cover 30 is disposed on the front surface of the fan 10 and the rear cover 40 is disposed on the rear surface of the fan 10 to prevent a safety accident from occurring as the fan 10 rotates .

Here, the front cover 30 is partially opened to allow the wind generated by the rotation of the fan 10 to pass therethrough. At this time, the front cover 30 can be implemented in various forms, but it is opened at intervals such that the fingers can not easily pass through for safety reasons.

On the other hand, the rear cover 40 may be partially open or closed depending on the operation mode of the fan. In other words, the rear cover 40 can be realized so that the front surface is closed so that the rear wind can be sucked well in the direction of the fan 10 in the fan mode and the heated wind can not be leaked in the rear mode in the hot air mode have. At this time, the rear cover 40 is implemented as a double lid to facilitate opening and closing of a part of the surface, and a part of the surface can be opened and closed by rotating the inner lid in the left / right direction.

The rear cover 40 is made of an aluminum material having a high reflectance inside so as to increase the reflectance of the heat generated by the heat ray 50 in the front direction when the front surface is closed in the hot air mode.

Here, the inner cover of the rear cover 40 may be automatically opened or closed according to the operation mode selection by a motor operation or the like, but it may be manually opened or closed by a user. When the inner lid of the rear lid 40 is manually opened and closed, the handle may be separately arranged to facilitate the user's operation.

The hot wire 50 is disposed between the fan 10 and the rear cover 40 and receives power from the power supply means in the hot air mode to generate heat. The heat generated by the heat ray 50 heats the wind generated by the fan 10 and can be reflected to the inside of the rear cover 40 and diverted to the front direction.

In other words, when the fan 10 rotates in one direction, wind is generated in the front direction, and when the fan 10 rotates in the other direction, wind is generated in the rear direction. Therefore, the wind generated in the rear direction in the hot air mode is heated by the heat generated from the hot wire 50, reflected by the inner side of the rear cover 40, and discharged in the front direction.

2 is a block diagram showing the configuration of a control unit of a combined heat and air fan according to the present invention. Referring to FIG. 2, the control unit 100 of the combined heat and air fan according to the present invention includes a switching unit 110 and a control unit 120.

First, the switching unit 110 can receive a mode selection signal by operating a mode selection switch provided outside the body of the hot air, and operates the remote controller to wirelessly communicate with the hot air in the remote place, You can also get input.

The switching unit 110 switches the operation mode of the hot air blower according to an input signal from a mode selection switch or a remote controller at a remote place. For example, the switching unit 110 may switch the fan mode to the hot air mode or switch the hot air mode to the fan mode. At this time, the switching unit 110 outputs the information of the mode switched to the controller 120 upon switching the operation mode of the hot air.

The control unit 120 generates a control signal corresponding to the operation mode by switching the operation mode of the switching unit 110 and outputs the generated control signal to the related driving unit.

In other words, when the control unit 120 is switched to the fan mode by the switching unit 110, the control unit 120 generates a first control signal corresponding to the fan mode and outputs the first control signal to the drive motor 20. [ At this time, the control unit 120 may control the power supply unit 60 to cut off power supply to the hot wire.

Accordingly, the drive motor 20 can rotate the drive shaft 15 in one direction by the first control signal from the control unit 120, and cool air can be generated by the fan. Here, when the inner lid of the rear cover is automatically opened and closed, the opening / closing means can automatically open a part of the surface by the driving force of the driving motor 20. [ On the other hand, the controller 120 can control the inner cover of the rear cover to be opened by outputting a control signal to the opening / closing controller 70. If the inner lid of the rear lid is manually opened or closed, the user can be informed to open the inner lid of the rear lid through a separate alarm means (not shown).

Meanwhile, when the switching unit 110 switches the mode to the hot air mode, the controller 120 generates a second control signal corresponding to the hot air mode and outputs the second control signal to the driving motor 20. At this time, the control unit 120 may control the power supply unit 60 to supply power to the hot wire.

Accordingly, the drive motor 20 rotates the drive shaft 15 in the other direction by the second control signal from the controller 120, so that wind can be generated by the fan. Further, when the inner lid of the rear cover is automatically opened and closed, the opening / closing control means 70 can automatically close some surfaces by the driving force of the driving motor 20. [ On the other hand, the controller 120 may control the inner cover of the rear cover to be closed by outputting a control signal to the opening / closing controller 70. If the inner cover of the rear cover is manually opened and closed, the user can be notified through the separate alarm means that the inner cover of the rear cover is closed.

FIG. 3 shows the shape of the rear cover when switching from the fan mode to the hot air mode, and FIG. 4 shows the shape of the rear cover when switching from the hot air mode to the fan mode.

The back cover is to be opened partially to allow air to flow in from behind when the hot air fan operates in the fan mode.

At this time, the rear cover is realized in the form of a double lid, and a part of the surface can be opened and closed by rotating the inner lid in the left / right direction. Here, the inner cover of the rear cover can be opened and closed in various forms.

As an example, the inner lid of the rear cover can be automatically opened and closed by the driving force of the driving motor. In addition, the hot air can be provided with opening / closing means for opening / closing the inner cover of the rear cover according to the operation mode selection. In this case, the opening / closing means may open / close the inner lid of the rear cover by a control signal of the control unit.

On the other hand, the inner cover of the rear cover may be manually opened and closed by the user.

Here, the inner cover of the rear cover is partially opened when operating in the fan mode. As shown in FIG. 3 (a), when the operation mode is switched to the hot air mode in a state where a part of the inner surface of the inner lid is open, as the inner lid is rotated from the left to the right, The opened face is closed.

On the other hand, when the inner lid of the rear cover operates in the hot air mode, the entire surface is closed.
