    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Reference will now be made in detail to the present preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures. [0022]
  • As illustrated in FIGS. 1 and 2, an air circulating device according to an embodiment of the present invention includes a [0023] housing 10 which has a front casing 11 and a rear casing 12. The front and rear casings 11 and 12 are removably assembled with each other. An air inlet port 13 is provided at a front of the front casing 11 of the housing 10 to suck indoor air into the housing 10. An air outlet port 14 is provided on an outer circumferential surface of the rear casing 12 of the housing 10 to discharge air to a room.
  • Further, an axial blowing [0024] fan 15 and a motor 16 are set in the housing 10. The blowing fan 15 forcibly circulates indoor air so that indoor air is sucked into the air inlet port 13 of the housing 10, and is discharged through the air outlet port 14 to the room. The motor 16 drives the blowing fan 15. In this case, the motor 16 comprises a reversible motor which is able to rotate in alternating directions. The motor 16 is mounted at a surface thereof to a center of an inner surface of the rear casing 12.
  • As illustrated in FIG. 1, a [0025] plug 20 is integrally provided at an upper portion of the rear casing 12 of the housing 10 to be connected to a wall-mounted socket 100. Such a construction allows the housing 10 to be held by the wall-mounted socket 100 while allowing power to be applied to the motor 16, when the plug 20 is connected to the socket 100.
  • A built-in [0026] electrical socket 21 is integrally provided at a surface of the housing 10 opposite to the surface having the plug 20, thus allowing a plug 30 of another electrical device to be connected to the socket 21. Thus, although the air circulating device is connected to the wall-mounted socket 100 and covers the socket 100, it is possible to connect the plug 30 of another electrical device to the built-in socket 21 which is provided at the upper portion on the front of the housing 10.
  • Further, a [0027] power switch 41 and a mode conversion switch 42 are provided at a predetermined portion of the housing 10. The power switch 41 functions to control the operation of the motor 16. The mode conversion switch 42 functions to change the rotating direction of the blowing fan 15 by converting power applied to the motor 16. When the rotating direction of the blowing fan 15 is changed by the mode conversion switch 42, the air blowing direction is changed, so the air inlet port 13 serves as an air outlet port, while the air outlet port 14 serves as an air inlet port.
  • FIG. 3 illustrates an air circulating device according to another embodiment of the present invention. According to the air circulating device illustrated in FIG. 3, a [0028] timer 50 is mounted to a predetermined portion of the front casing 11 so as to control an operating time of the blowing fan 15. The timer 50 allows a user to preset the operating time, thus making the air circulating device more convenient to use.
  • Examples of use of the air circulating device according to the present invention will be described in the following. [0029]
  • The air circulating device of the present invention may serve as an auxiliary air circulating device in a room where an air conditioner or an air cleaner is installed, thus enhancing circulating efficiency of indoor air. Alternatively, the air circulating device may be installed in a room without the air conditioner or the air cleaner, thus circulating indoor air and ventilating the room. [0030]
  • When one desires to use the air circulating device, as illustrated in FIG. 4, the [0031] plug 20 of the housing 10 is connected to the wall-mounted socket 100. Next, the power switch 41 is turned on to operate the air circulating device. At this time, the blowing fan 15 set in the housing 10 is operated, so indoor air is sucked into the air inlet port 13 of the housing 10 and is discharged through the air outlet port 14 to the room in a radial direction, thus circulating the indoor air. When one desires to change the air blowing direction, the mode conversion switch 42 is manipulated so that the blowing fan 15 is rotated in an opposite direction. Further, it is possible to preset a desired operating time using the timer 50.
  • Meanwhile, when one desires to use another electrical device during an operation of the air circulating device, as illustrated in FIG. 1, a user has only to connect the [0032] plug 30 of another electrical device to the built-in socket 21 which is integrated with the housing 10 of the air circulating device.
  • As illustrated in FIG. 5, when one desires to place the air circulating device at a center or other desired position of a room to enhance air circulation as well as a ventilating effect, a user has only to use an [0033] extension cable 60.
  • In another embodiment of the present invention the [0034] housing 10 of the air circulating device is equipped with a unit to support a scented material, such as an oil or other liquid or solid air freshener, which will add a pleasant fragrance to the indoor air that is being circulated. In normal operation of the air circulating device, as shown in FIGS. 4 and 5, the scented material would be mingled with the air before it leaves the air outlet port 14, producing a pleasing smell with the circulated indoor air.
  • As is apparent from the above description, the present invention provides an air circulating device, which serves to circulate indoor air as an auxiliary device of an air conditioner or an air cleaner, and which also serves as an independent air circulating device, thus keeping a comfortable circulation of indoor air inside a room. [0035]
  • The present invention provides an air circulating device, which is small in size, thus being easily connected to a socket, and thus being easy to carry and store. [0036]
  • Furthermore, the present invention provides an air circulating device which allows a plug of another electrical device to be connected to a socket provided at an upper portion of a housing. [0037]
  • Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
