- the type of dryer is classified into a condensation type and an exhaust type according to a method of treating the high temperature and high humidity air.
- the condenser dryer condenses the moisture contained in the hot humid air through heat exchange while circulating without discharging the hot humid air to the outside.
- the exhaust dryer directly discharges hot and humid air to the outside.
- the condensation dryers have a structure for treating condensed water, and the exhaust dryers have a structural difference from each other in that they have a structure for exhausting air.
- the condensation dryer may include a heater system that generates joule heat to condense moisture through a heat exchange process, or a heat pump system using a refrigerant. Regardless of which heat exchange system the dryer has, the heat exchange efficiency affects the power consumption or performance of the dryer.

- the compressor 1120 is an element constituting the heat pump cycle devices 1100, but does not need to be installed in the air circulation passage because it does not directly exchange heat with air. Rather, since the compressor 1120 may interfere with the flow of air if the compressor 1120 is installed in the air circulation passage, the compressor 1120 is preferably installed outside the air circulation passage as shown in FIG. 3.
- the compressor cooling fan 1720 generates wind toward the compressor 1120 or in the direction of sucking air from the compressor 1120. When the temperature of the compressor 1120 is lowered by the compressor cooling fan 1720, the compression efficiency is improved.
- the gas-liquid separator 1140 is installed upstream of the compressor 1120 based on the flow of the refrigerant.
- the gas-liquid separator 1140 separates the gaseous phase and the liquid phase of the abnormal refrigerant introduced into the compressor 1120 so that only the gas phase flows into the compressor 1120.

- the drum motor 1800 is installed in front of the compressor 1120.
- the drum motor 1800 has an output shaft that protrudes in both directions.
- a portion of the output shaft protruding to one side of the drum motor 1800 is called a first output shaft
- another portion of the output shaft protruding to the other side of the drum motor 1800 is called a second output shaft.
- the first output shaft and the second output shaft are one rotation shaft, they rotate in the same direction and at the same speed.
- the first output shaft and the second output shaft are exposed in opposite directions.

- a drum belt (not shown) is coupled to the pulley 1810, and a driving force of the drum motor 1800 is transmitted to the drum 1030 through the drum belt.
- the drum 1030 is rotated by the driving force of the drum motor 1800 transmitted through the pulley 1810 and the drum belt.
- the rotational speed of the drum 1030 is controlled by the pulley 1810. Since the drum belt is not directly connected to the first rotation shaft, the rotation speed of the drum 1030 does not necessarily coincide with the rotation speed of the first output shaft.
- the blowing fan 1820 is installed on the second output shaft.
- the blowing fan 1820 is configured as an axial fan generating wind in a direction from the rear of the clothes processing apparatus 1000 to the front.

- the direction of sucking air from the drum motor 1800 refers to the direction from the first output shaft toward the second output shaft.
- the drum motor 1800 may be cooled by the blowing fan 1820. Since the blowing fan 1820 is directly connected to the second output shaft, the rotational speed of the blowing fan 1820 coincides with the rotational speed of the second output shaft.

On the other hand, if the number of vanes 1822 is odd, the vibration is smaller than in the even number. It can be seen from FIG. 3 that the number of vanes 1822 is five.
- the sealing of the drum 1030 may not be perfect, when the blower fan 1820 rotates, condensation may be suppressed due to incomplete sealing of the drum 1030. For example, it is difficult to completely exclude the discharge of hot and humid air into the space between the inner circumferential surface of the drum 1030 and the inner circumferential surface of the cabinet 1010. In particular, when the air leaked from the drum 1030 is stagnant, it causes condensation.
- blower fan 1820 produces convection, congestion of air leaked from the drum 1030 is suppressed and condensation is suppressed. Air leaked from the drum 1030 is exhausted while continuously flowing by the blower fan 1820.
- the time required for rotation of the blowing fan 1820 is the same as the time when the drum 1030 rotates. This is because hot dry air is supplied to the drum 1030 while the drum 1030 is rotating, and hot and humid air may leak from the drum 1030. Therefore, a situation in which power is not consumed unnecessarily to rotate only the blower fan 1820 in a state in which the rotation of the drum 1030 is unnecessary.

- the blowing fan 1820 should be distinguished from the structure of cooling the drum motor 1800 by sucking external air through the front part of the cabinet 1010 in consideration of the wind direction.
- a hole must be formed in the front portion of the cabinet 1010, and wind must be formed in the direction of sucking outside air through the hole.
- the blower fan 1820 of the present invention is for suppressing condensation occurring in the space between the cabinet 1010 and the drum 1030 rather than cooling the drum motor 1800. Therefore, the front of the blowing fan 1820 should be blocked by the front portion of the cabinet 1010 that is spaced apart from the blowing fan 1820. If a hole is formed in the front portion of the cabinet 1010, the wind generated by the blower fan 1820 escapes to the outside of the cabinet 1010 through the hole, thereby reducing the condensation prevention effect through convection.
