As shown, the drying apparatus 100 according to an embodiment of the present invention forms an exterior and rotates inside the cabinet 110 and the cabinet 110 in which each component forming the drying apparatus 100 is installed. The drum 130 may be coupled to accommodate the object to be dried, a driving unit 140 for rotating the drum, and an air supply device 150 for circulating air (or hot air) into the drum 130.

On the other hand, on the air flow path of the air supply device 150 is provided with a filter unit 160, the filter assembly (200, 300) is mounted for filtering the lint generated from the clothing processed in the drum (130).

An opening 111 for injecting a drying object is formed in front of the cabinet 110. The opening 111 has a door 112 for opening and closing the opening 111 at one side. On the other hand, the cabinet 110 is provided with a control panel (not shown) for operating the setting of the drying apparatus 100, or to display the setting state of the drying apparatus 100 on the top.

On the other hand, the door 112 is provided with a transparent door glass 114 so that the user can observe the drying process. The door glass 114 is typically formed in a conical column shape that protrudes toward the drum 130 in order to reinforce the strength of the door glass 114 itself and prevent the object to be moved to the door 112 side.

The drum 130 is formed in a cylindrical shape with the front and the rear open. The drum 130 has a front supporter 132 that rotatably supports the drum 130 in front. In addition, the drum 130 has a rear supporter 133 rotatably supporting the drum 130 at the rear thereof. In addition, the front and rear lower roller supporters 134 and 135 in the form of rollers rotatably supporting the drum 130 may be further provided. That is, the front supporter 132 and the rear supporter 133 form a drying chamber by blocking the front and rear surfaces of the drum 130 and at the same time serve to support the front and rear ends of the drum 130.

On the other hand, the front supporter 132 is formed with a front opening 132a for communicating the drum 130 with the outside of the drying apparatus 100. The opening 132a is selectively opened and closed by the door 112. The exhaust duct 153 of the air supply device 150 to be described later is located below the front supporter 132.

The rear supporter 133 is provided with a plurality of air supply holes 133a which are passages through which air is supplied to the drum 130. The plurality of air supply holes 133a are connected to the air supply duct 152 of the air supply device 150 described later.

The driving unit 140 includes a motor 141 and a belt 143. The motor 141 includes two rotation shafts, and one side rotation shaft of the motor 141 includes a pulley 142. The pulley 142 is connected to the belt 143 winding the drum 130. As the motor 141 rotates, the pulley 142 is rotated, and the rotational force of the pulley 142 is transmitted to the drum 130 by the belt 143 to rotate the drum 130. The other rotating shaft of the motor 141 is connected to the blowing fan 151 of the air supply device 150 to be described later.

That is, the drum 130 is supported by the front supporter 132 at the front, the rear is supported by the rear supporter 133, so that only the cylindrical body portion of the drum 130 is rotated by the rotational force of the driving unit 140. Is formed.

The air supply device 150 includes an exhaust duct 153 through which the air of the drum 130 is exhausted, a blowing fan 151 for sucking and discharging air from the exhaust duct, and air discharged by the blowing fan 151. The air supply duct 152 for guiding the drum 130 is provided.

Here, the exhaust duct 153 is provided to connect between the front lower portion of the front supporter 132 and the blowing fan 151.

The filter unit 160 may further include filter assemblies 200 and 300 for filtering the air exhausted from the drum 130. The filter assemblies 200 and 300 will be described later.

In addition, the air supply duct 152 is provided to connect between the rear supporter 133 and the blowing fan 151. The air supply duct 152 supplies the supplied air to the drum 130 through the air supply hole 133a.

A condenser 155 is provided between the blowing fan 151 and the air supply duct 152. The condenser 155 dries the object to be dried and dehumidified air. The condenser 155 further includes a separate external air duct 154 for sucking air outside the drying apparatus 100 for dehumidifying the air. In addition, the air supply duct 152 further includes a heater 152a for heating the air moved to the drum 130.

The heater 152a heats the introduced dry air when the humid air circulated by the blowing fan 151 after the completion of drying is introduced into the air supply duct 152 after being dehumidified through the condenser 155 to be described later. The dried air is heated by the heater 152a and supplied to the drum 130 through the air supply duct 152.

That is, when the drum 130 rotates and the air inside the drum 130 is exhausted through the exhaust duct 153 by the blowing fan 151, the air heated through the air supply duct 152 is inside the drum 130. Will be sucked into. At this time, the heater 152a is installed in the inlet end or the air supply duct 152 into which air is introduced into the air supply duct 152 so that the heated air can be supplied into the drum 130 through the air supply duct 152. It is preferable.

On the other hand, the condenser 155 is installed between the blowing fan 151 and the air supply duct 152 to dehumidify the humid air exhausted through the exhaust duct 153 to be supplied to the air supply duct 152 again. Condenser 155 may be used in both air-cooled or water-cooled condenser.

In the case of using an air-cooled condenser, moisture is condensed through the thermal effect by supplying air to the condenser, which is relatively cooler than air after drying. In the case of using a water-cooled condenser, moisture is condensed through heat exchange by supplying a refrigerant or cooling water to the condenser.

Condensate generated when using an air-cooled or water-cooled condenser is drained to the outside through a separate drain pump (not shown). In the present invention, the air-cooled condenser has been described as an example for convenience.

Such, the drying apparatus 100 has a filter assembly (200, 300) for filtering the lint generated during drying of clothes. The filter assemblies 200 and 300 may be installed on a path through which air moves. Preferably it is located at the front end of the air of the drum 130 is exhausted. To this end, a filter unit 160 in which the filter assemblies 200 and 300 are mounted is formed at the front end of the exhaust duct (that is, the position where the exhaust duct and the front duct meet).

On the other hand, when the drying stroke continues, foreign matters such as lint are stacked on the filter assemblies 200 and 300. If the lint filter is not cleaned for a long time, the air volume decreases, and thus the drying efficiency is lowered. Therefore, after the use of the dryer is complete, the user has to take out the lint filter every time to remove the lint.

In order to solve this problem, the present invention provides a filter assembly (200, 300) that can automatically clean the lint filter to improve the user's convenience, and to solve the problems caused by air flow and temperature overheating.

Hereinafter, a filter assembly according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
