Abstract

A drying apparatus includes a main body composed of a front end frame and a rear end frame. A fan receiving part may be disposed on the upper end of the front end frame and protruding forward therefrom, and a fan assembly may be located in the fan receiving part. The open part may be disposed at the lower part of the fan receiving part of the front end frame, and the outlets may be located along the upper end edge and opposite edges of the open part. Air may be delivered to the outlets through the duct disposed at the main body.

First claim

What is claimed is:

1. A drying apparatus comprising:
a main body having an entrance hole through which air is introduced thereinto and front outlets disposed at a front surface of the main body through which the air is discharged;
a fan assembly disposed at the main body to generate a flow of the air; and
a duct communicating with the fan assembly to receive the flow of the air and having at least two flow paths to divide the flow of the air such that the divided flow of the air is delivered to the respective front outlets,
wherein the front outlets communicate with second outlets disposed at the duct and allow the air delivered through the duct to be discharged from the front surface of the main body.

2. The drying apparatus of claim 1 , wherein the front outlets are disposed at a front plate constituting the front surface of the main body along positions adjacent to edges of the main body.

3. The drying apparatus of claim 1 , further comprising a connection tube disposed between the front outlets and the second outlets, and has a flow cross-sectional area gradually decreasing toward the front outlets from the second outlets.

4. A drying apparatus comprising:
a main body having an entrance hole through which air is introduced thereinto and having outlets through which the air is discharged toward a front of the main body;
a fan assembly disposed at the main body to generate a flow of the air; and
a duct communicating with the fan assembly to receive the flow of the air and having at least two flow paths to divide the flow of the air such that the divided flow of the air is delivered to the respective outlets,
wherein the duct includes a first flow path and a second flow path through which the air introduced by the fan assembly flows,
wherein the air flowing through the first flow path is discharged through outlets arranged along a first edge of the main body; and the air flowing through the second flow path is discharged through outlets arranged along a second edge of the main body.

5. The drying apparatus of claim 4 , further comprising a filter assembly installable at the entrance hole to purify the air introduced to the fan assembly.

6. The drying apparatus of claim 4 , further comprising:
a front end frame and a rear end frame constituting an exterior of the main body;
a fan receiving part at an upper end of the front end frame in which the fan assembly is disposed; and
an open part at a front surface of the front end frame except for the fan receiving part.

7. The drying apparatus of claim 6 , further comprising a front plate disposed at the open part to separate an inside of the main body from an outside thereof, and the outlets are arranged in positions corresponding to an upper end edge of the open part and opposite side edges thereof.

8. The drying apparatus of claim 6 , further comprising a first vane and a second vane disposed along the upper end edge and the opposite side edges of the open part to guide the air discharged through the outlets toward the front of the main body.

9. The drying apparatus of claim 8 , wherein each of the first vane and the second vane extends to have a predetermined inclination toward a center of a front surface of the main body.

10. The drying apparatus of claim 4 , wherein each of the first flow path and the second flow path of the duct is connected to each other by a connection flow path at a lower flow part thereof, and a lower discharge flow path is formed through a lower end part of the main body from the connection flow path.

11. The drying apparatus of claim 4 , wherein each of the first flow path and the second flow path has an inclination part disposed to be adjacent to the respective outlets, and has a flow cross-sectional area gradually decreasing toward the respective outlets.

12. The drying apparatus of claim 4 , further comprising a controller disposed at a space formed where the first flow path and the second flow path of the duct are separated from each other, the controller configured to control a driving of the fan assembly.

13. A drying apparatus comprising:
a main body having an entrance hole through which air is introduced thereinto and having outlets through which the air is discharged toward a front of the main body;
a fan assembly disposed at the main body to generate a flow of the air;
a duct communicating with the fan assembly to receive the flow of the air and having at least two flow paths to divide the flow of the air such that the divided flow of the air is delivered to the respective outlets;
a front end frame and a rear end frame constituting an exterior of the main body;
a fan receiving part at an upper end of the front end frame in which the fan assembly is disposed;
an open part at a front surface of the front end frame except for the fan receiving part; and
a front plate disposed at the open part to separate an inside of the main body from an outside thereof, and the outlets are arranged in positions corresponding to an upper end edge of the open part and opposite side edges thereof.

14. A drying apparatus comprising:
a main body having an entrance hole through which air is introduced thereinto and having outlets through which the air is discharged toward a front of the main body;
a fan assembly disposed at the main body to generate a flow of the air;
a duct communicating with the fan assembly to receive the flow of the air and having at least two flow paths to divide the flow of the air such that the divided flow of the air is delivered to the respective outlets;
a front end frame and a rear end frame constituting an exterior of the main body;
a fan receiving part at an upper end of the front end frame in which the fan assembly is disposed;
an open part at a front surface of the front end frame except for the fan receiving part; and
a first vane and a second vane disposed along the upper end edge and the opposite side edges of the open part to guide the air discharged through the outlets toward the front of the main body.
