In addition, the cover protect 230 is installed to protect the circuit board 220 from the back, and serves as a partition wall separating the inner region of the control unit 200 and the inner region of the main body 100. At this time, the cover protect 230 is preferably a non-combustible material.

Here, the cover protect 230 is preferably formed with a plurality of heat dissipation holes 231 through which the inside of the control unit 200 and the inside of the main body 100 pass.

This is to allow the internal air of the control unit 200 and the external air of the control unit 200 to be smoothly ventilated with each other.

That is, when the clothes dryer operates, the internal temperature of the control unit 200 and the external temperature of the control unit 200, which are relatively low temperature, are heat exchanged through the heat radiating hole 231 of the cover protect 230, thereby controlling the control unit ( 200) This is to prevent the continuous temperature rise inside.

At this time, the heat dissipation hole 231 is preferably lancing (lancing), it is more preferably formed in the longitudinal direction of the cover protect 230.

In addition, the heat radiating hole 231 is preferably formed corresponding to the rotational direction of the drying drum 300 installed in the main body 100. This is to allow air outside the control unit 200 at a relatively low temperature to flow into the control unit 200 due to the flow of air generated when the drying drum 300 is rotated.

At this time, the heat dissipation hole 231 is preferably formed in a width of less than 3mm.

On the other hand, the heat radiating hole 231 may be formed in the horizontal direction of the cover protect 230.

In addition, the drying drum 300 is provided in the main body 100 with a predetermined space to accommodate the drying object.

The hot air supply passage 400 is dried while the air sucked is heated on one side of the hot air supply passage 400. Preferably, the heater 600 is installed at one side to be supplied into the drum 300.

At this time, the hot air supply passage 400 is preferably installed on the rear of the drying drum (300).

Then, the hot air discharge passage 500 serves as a pipe for discharging the external air sucked into the drying drum 300 to the outside again, one side of the hot air discharge passage 500 sucks the external air into the drying drum 300 In addition, the exhaust fan 700 for discharging to the outside of the main body 100 is preferably installed.

On the other hand, the motor 800 generates power to transmit the drying drum 300 to the driving pulley 810, it is preferably installed on the lower side of the main body (100). In this case, the belt 820 for transmitting the rotational force of the driving pulley 810 to the drying drum 300 is preferably connected to the driving pulley 810 and the drying drum 300, respectively.

Or more, if the description of the operation of the drum-type clothing gun early and the control unit according to an embodiment of the present invention having the above-described configuration as follows.

First, after the drying object is put into the drying drum 300 through the inlet 110 of the main body 100, and when the clothes dryer is operated, the heater 600 and the exhaust fan 700 are operated and the motor ( Voltage is applied to the 800 and the drying drum 300 is rotated by the power of the motor 800.

At this time, the flow of air occurs in the direction of rotation of the drying drum 300, the air is relatively low compared to the internal temperature of the control unit 200 is controlled by the lanced heat radiating hole 231 of the cover protect 230 It flows into the inside of the part 200.

In addition, the outside air introduced into the main body 100 by the exhaust fan 700 is changed to hot air that has become hot while passing through the heater 600 installed on one side of the hot air supply passage 400 to be forced into the drying drum 300. Inflow.

At this time, as the drying object accommodated in the drying drum 300 is pulled up and dropped by the stirring piece 310, the moisture of the drying object is evenly evaporated by hot air, and the humid air generated in this process is a hot air discharge passage ( It is discharged to the outside of the main body 100 through 500.

The temperature inside the drying drum 300 is increased by hot air circulated in the repeated drying process as described above, and in particular, the internal temperature of the control unit 200 is increased.

However, as described above, by flowing the flow of air generated by the rotation of the drying drum 300 through the heat dissipation hole 231 of the cover protect 230, the temperature inside the high temperature control unit 200 and relatively low temperature As the temperature outside the control unit 200 is exchanged with heat, a constant temperature increase inside the control unit 200 does not occur.

At this time, the lanced heat radiating hole 231 serves to guide the flow of air generated by the rotation of the drying drum 300, so that the air outside the control unit 200 more smoothly into the control unit 200 inside It can flow in.

However, despite the structure of the cover protect 230 as described above, for example, even if the flame is generated by the flame caused by the malfunction of the circuit elements mounted on the circuit board 220, the flame is spread throughout the clothes dryer. Also, it does not occur.

That is, since the heat dissipation hole 231 formed in the cover protect 230 is a lanced form pressurized to the circuit board side from the side where the drying drum 300 is installed, the heat dissipation hole 231 does not have a through hole toward the circuit board. The through hole is formed in a direction perpendicular to the circuit board.

Therefore, the flame generated from the circuit board may not easily leak the heat dissipation holes 231 of the cover protect 230.

In particular, since the size of the heat dissipation hole 231 is 3mm or less, it is more difficult for the flame to leak out of the cover protect 230, so that the flame does not spread to the whole body.

On the other hand, the embodiment of the present invention as described above is configured to help the understanding of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope without departing from the spirit of the present invention.

According to the control unit of the clothes dryer according to the embodiment of the present invention, a plurality of heat radiation holes are formed in the cover protect, during operation of the drum type clothes dryer, the low temperature air and the control unit introduced into the control unit while the drying drum is rotated The internal hot air is exchanged with each other to prevent a constant temperature rise inside the control unit.

And, when a flame occurs inside the control unit, the flame does not leak to the outside of the control unit can prevent the flame from spreading throughout the air dryer.
