3 to 10, a dryer according to an embodiment of the present invention forms a predetermined space, an opening is formed at one side, and a cabinet 50 having an inlet 52 and an outlet 54 formed therein and an opening inside. A drum (60) rotatably installed on the drum (60) for storing laundry, a plurality of lifters (100) installed on the inner wall of the drum (60) to rotate the laundry, and air in the cabinet (50) to the drum (60). An intake pipe 70 for guiding, a heater 74 provided in the intake pipe 70, an exhaust fan 82 provided between the drum 60 and the discharge port 54, an exhaust fan 82, It includes an exhaust pipe 80 provided between the discharge port 54 and the drive motor 90 is connected to the rotation shaft of the exhaust fan (82).

Thus, when the power is applied to the drive motor 90 by the user's operation, the exhaust fan 82 is rotated to circulate air, and the air introduced through the suction port 52 is hot while passing through the heater 74. The air is converted into air and supplied into the drum 60, and the drying operation or sterilization operation of the clothes is performed while contacting the clothes in the drum 60.

Thereafter, the air discharged by the exhaust fan 82 is discharged to the outside through the discharge port 54 of the cabinet 50 along the discharge pipe 80, thereby circulating the air.

Here, the discharge port 54 is formed at the bottom of the rear surface of the cabinet 50 in the center.

In addition, the drum 60 is formed in a cylindrical shape with a front surface and a rear surface opened so that the front surface corresponds to the opening portion, and the rear surface is rotatably installed on the support panel 62 having the through hole portion 62a formed therein.

Here, the support panel 62 is installed on the rear inner wall of the cabinet 50 so that the drum 60 can be rotatably supported, and the intake pipe 70 is installed in the through hole portion 62a.

In addition, the drum 60 is provided with a gasket 64 between the front end and the opening of the cabinet 50, and a discharge port 64a is formed at the lower end of the gasket 64.

An extension pipe 86 facing the exhaust fan 82 side is provided at this discharge port 64a, and a housing 84 is installed between the extension pipe 86 and the exhaust pipe 80 so that the exhaust fan 82 is rotatably embedded. .

The intake pipe 70 includes a passage extending from the lower end of the cabinet 50 to the upper portion of the rear surface of the cabinet 50 corresponding to the through hole portion 62a, so that air introduced from the inside of the cabinet 50 causes the heater 74 to flow. As it passes, the air is converted into air having a predetermined temperature or more, and is moved upwardly of the cabinet 50 along the intake pipe 70, and is introduced into the drum 60 through the through hole part 62a.

At this time, as the drum 60 connected to the drive motor 90 and the belt 96 is rotated, the contact area of the laundry with hot air is increased, so that drying or sterilization of the laundry is performed.

Here, the heater 74 is installed inside the intake pipe 70 installed in the cabinet 50, so that the heater 74 is compared with the prior art in which the heater 74 is installed on the bottom side of the inside of the cabinet 50. And the distance between the drum 60 is minimized.

As a result, the heat loss generated while the air heated above the predetermined temperature by the heater 74 moves along the intake pipe 70 may be minimized, thereby maximizing the efficiency of the dryer.

In addition, since the heater 74 is installed on the rear side of the cabinet 50, the heater 74 is disposed in a separate space from the driving motor 90 which is easily overheated, thereby preventing the cabinet 50 from being overheated more than necessary. Effects of preventing malfunction and damage of the dryer due to overheating of the driving motor 90 are generated.

Here, the intake pipe 70 is formed with a curved portion 102 at the bent portion, the air flowing along the inner wall of the intake pipe 70 by the curved portion 102 does not interfere with the inner wall of the intake pipe 70. It can be smoothly flow along the curved portion 102 without.

The curved portion 102 is formed on the upper and lower ends of the intake pipe 70 so as to slide smoothly along the curved portion 102 when the flow path of air introduced through the inlet 52 is converted to the upper side to achieve a smooth change of direction. When the air flowing upwards is slid along the curved portion 102 when the air flows toward the through hole portion 62a, the air flows smoothly and the vortices are prevented from occurring inside the intake pipe 70. Will flow.

In addition, the intake pipe 70 has a main body 72 formed long in the up and down direction, and a through hole portion 62a formed at the lower end thereof and communicating with the drum 60 at the upper end thereof. Cover 73 is coupled to the ()), and both ends of the main body 72 is cut and bent to the coupling piece (72a) is provided with a heater (74).

And the heater 74 is formed in the fixed panel 74a fastened to the engaging piece 72a, the coil 74b provided in the fixed panel 74a, and the fixed panel 74a between the coil 74b. It includes the protrusion 74c.

In this way, after the fixing panel 74a provided with the coil 74b is fastened to the engaging piece 72a of the main body 72, the main body 72 and the cover 73 are joined to each other, whereby the intake pipe 70 and the heater 74 are connected. ) Can be assembled.

The intake pipe 70 thus assembled is inclined at a predetermined angle (a) from the vertical direction so that the flow path of air supplied into the drum 60 is extended.

Since the intake pipe 70 is installed to be inclined so that its length is longer than the intake pipe installed in the vertical direction, the effect of increasing the distance that the air passing through the heater 74 flows to the drum 60 is generated. Therefore, the inside of the drum 60 can be prevented from being heated more than necessary by the air heated by the heater 74.

In addition, the coil 74b of the heater 74 is installed to be inclined to the fixed panel 74a, which is the same as the inclination angle a of the intake pipe 70 and is inclined in the opposite direction, thereby making it perpendicular to the vertical direction. Is placed.

As a result, the degree of contact between the air flowing in the vertical direction and the coil 74b remains the same in the intake pipe 70, so that both the left side and the right side inside the intake pipe 70 are heated the same.

Therefore, the hot air injected into the drum 60 maintains a similar temperature on both the left side and the right side of the through hole 62a, so that the inside of the drum 60 is heated to a uniform temperature.

In addition, the protrusion 74c is formed by cutting a portion of the fixed panel 74a to be bent to one side or the other side, and the air passing through the heater 74 because the protrusion 74c is formed between the coil 74b and the coil 74b. Is collided with the protrusion 74c to generate a vortex at the portion in contact with the coil 74b.

When the vortex is generated in the portion where the coil 74b is disposed in this way, the contact amount between the air and the coil 74b is increased, thereby improving the thermal efficiency of the heater 74.

Then, it is heated by high temperature dry air of predetermined temperature or more by the heater 74.

At this time, the air passing through the intake pipe 70 passes through the intake pipe 70 extending in length, by adjusting the capacity of the heater 74 and the degree of inclination of the intake pipe 70, by the heater 74 Heat loss generated while the heated air flows along the intake pipe 70 may be reduced, and the inside of the drum 60 may be prevented from being overheated more than necessary due to the adverse effect of preventing heat loss.

In addition, since the air flowing along the intake pipe 70 is prevented from colliding with the inner wall of the intake pipe 70 at the time of the change of direction by the curved portion 102, a smooth change of direction can be achieved.

In addition, since the air flowing along the intake pipe 70 passes through the heater 74 by the protrusion 74c, vortex is generated, so that the amount of contact with the coil 74b is increased, thereby improving thermal efficiency.

Thereafter, the air introduced into the drum 60 through the through-hole part 62a flows in a tornado shape and contacts the laundry to perform a drying operation.

In addition, the outlet 64a is formed in the gasket 64 provided between the opening of the drum 60 and the inner wall of the cabinet 50, and the air which has undergone the drying operation is discharged to the outside of the drum 60 along the outlet 64a. It is discharged and flows to the housing 84 of the exhaust fan 82 through the extension pipe 86 in communication with the discharge port 64a, is moved along the exhaust pipe 80 in the housing 84, the cabinet through the discharge port 54 50 is discharged to the outside.

As a result, the distance between the heater and the drum is minimized, thereby minimizing the heat loss generated by the flow of the heated air from the heater to the drum, thereby achieving a dryer in which thermal efficiency is maximized.
