Here, the cabinet may form the outer shape of the product, and at the same time, the clothing receiving unit 130 may be provided therein to accommodate the clothing. In the case of a drum-type clothes dryer, a clothes receiving unit 130 (hereinafter, referred to as a “drum”) may be installed inside the cabinet to accommodate clothes. The drum 130 may rotate about a rotation shaft disposed in a horizontal direction or in a direction inclined at a predetermined angle inside the cabinet. On the other hand, the drum 130 has a hollow cylindrical shape, and provides an accommodation space for putting clothes, which is an object to be dried, to dry.

On the other hand, an opening is formed in the front surface of the drum 130, an inlet is formed in the front surface of the cabinet, and the opening and the inlet are communicated with each other, so that clothes can be put into the drum 130. A door (not shown) may be installed in the cabinet in a hinge structure to open and close the inlet.

Here, in order to efficiently dry the clothes to be dried, the drum 130 is rotatably installed, and a lifter is provided inside the drum 130, so that the clothes can be tumbling by the lifter. .

In addition, the drive unit provides rotational force using a motor (not shown), the output shaft of the motor and the drum 130 are connected by a power transmission means such as a belt, and the rotational force of the motor is transmitted to the drum 130, (130) can be rotated.

In addition, the air passage 150 may be connected to the drum 130 to form a closed loop for circulation of air. For example, the air flow path 150 may be formed in a duct shape. A drum outlet for discharging air is formed at the lower front end of the drum 130, and a drum inlet for inflow of air is formed on the rear surface of the drum 130, and the air flow path 150 is in communication with the drum outlet and inlet. , It can induce air circulation.

On the other hand, the blowing fan 250 is an air flow path 150 extending from the drum outlet to the evaporator 210 of the heat pump 200 or the air flow path 150 extending from the condenser 220 of the heat pump 200 to the drum inlet. ) Can be installed inside. The blowing fan 250 may be driven by a separate fan motor, applies power to air to pass through the drum 130, and circulates the air discharged from the drum 130 back to the drum 130. In addition, a lint filter (not shown) is installed at the outlet of the drum 130 to collect lint contained in the air as air discharged from the drum 130 passes through the lint filter.

Therefore, clothing (also referred to as'cloth') evaporates moisture by hot air supplied into the drum 130, and the air passing through the drum 130 is discharged from the drum 130 while containing the moisture evaporated from the clothing. do. The high-temperature and high-humidity air discharged from the drum 130 is heated by receiving heat from the heat pump 200 while moving along the air flow path 150 and then circulated to the drum 130.

Meanwhile, the heat pump 200 includes an evaporator 210, a compressor 230, a condenser 220, and an expansion valve 240. The heat pump 200 may use a refrigerant as a working fluid. The refrigerant moves along the refrigerant pipe 260, and the refrigerant pipe 260 forms a closed loop for circulation of the refrigerant. The evaporator 210, the compressor 230, the condenser 220, and the expansion valve 240 are connected by a refrigerant pipe 260, so that the refrigerant is transferred to the evaporator 210, the compressor 230, the condenser 220, and the expansion valve. Pass through (240) in order.

Here, the evaporator 210 is installed in the air flow path 150 so as to communicate with the drum outlet, and exchanges heat between air and refrigerant discharged from the drum outlet, thereby recovering the amount of heat from the air discharged from the drum 130 without being thrown out of the dryer. do.

In addition, the condenser 220 is installed in the air passage 150 so as to communicate with the drum inlet, and exchanges heat between the air and the refrigerant passing through the evaporator 210, so that the amount of heat of the refrigerant absorbed by the evaporator 210 is transferred to the drum 130. It radiates heat with the air to be introduced into it.

Meanwhile, the evaporator 210 and the condenser 220 may be installed inside the air flow path 150. The evaporator 210 may be connected to the drum outlet, and the condenser 220 may be connected to the drum inlet.

The high-temperature and humid air discharged from the drum 130 has a higher temperature than the refrigerant in the evaporator 210, so as it passes through the evaporator 210, the amount of heat of the air is taken to the refrigerant in the evaporator 210, condensing water Occurs. Accordingly, moisture is removed by the evaporator 210, and the condensed condensed water may be collected through a condensed water collecting unit provided under the evaporator 210 and then discharged to the outside.

The heat source of the air absorbed from the evaporator 210 is moved to the condenser 220 via a refrigerant, and the evaporator (in order to move the heat source from the evaporator 210 (low heat source) to the condenser 220 (high heat source)) A compressor 230 is located between the 210 and the condenser 220.

Looking at the movement path of the refrigerant according to the configuration as described above, the refrigerant flows into the compressor 230 in a gaseous state and becomes high temperature and high pressure by compression of the compressor 230, and the high temperature and high pressure refrigerant flows into the condenser 220. As the condenser 220 discharges heat to air, it changes from a gaseous state to a liquid state.

Subsequently, the liquid refrigerant flows into the expansion valve 240 and changes to low temperature and low pressure by the throttling action of the expansion valve 240 (or capillary, etc.), and the low temperature and low pressure liquid refrigerant flows into the evaporator 210. As the evaporator 210 absorbs heat from the air, the refrigerant is evaporated from a liquid state to a gaseous state.

As such, the heat pump 200 repeatedly circulates the refrigerant through the compressor 230 → condenser 220 → expansion valve 240 → evaporator 210 and provides a heat source to the air circulated to the drum 130.

Meanwhile, the evaporator 210 may further include a vibrating unit 300 for removing condensed water generated on the surface of the evaporator 210 from the surface of the evaporator 210 by a predetermined vibration.
