The present invention relates to a drier, and more particularly, to a drum front sealing structure of a drier for preventing leakage of circulating air between a drum seated inside a drier and a front side of a drier.

1 is a cross-sectional view schematically showing a condensing drum dryer.

Referring to Figure 1, the condensation-type drum dryer for controlling the opening and closing of the cabinet 10, the cylindrical drum 12 formed inside the cabinet 10, and the drum 12 to form an appearance A door 13 and a belt 11 surrounding the outer circumferential surface of the drum 12 are included.

In addition, the motor shaft 21 is connected to the belt 11, the motor 17 is connected to the motor shaft to provide a rotational force, and the rotational force of the motor 17 is connected to the motor shaft 21 A cooling fan 16 that sucks and rotates the indoor air is included.

In addition, a drying fan 18 connected to the motor shaft 21 opposite the cooling fan 16 to circulate air inside the drum, and air sucked by the drying fan 18 may be connected to the drum ( As a passage to be moved to 12, the drying duct 19 is provided with a heat generating unit 20 therein.

In addition, a lint filter 14 formed below the opening through which the door 13 is inserted to filter foreign substances such as lint and the like contained in the wet air discharged from the drum, and air entering the lint filter 14 are condensers (not shown). It further includes a circulation duct 15 which is a passage to be moved to).

Hereinafter, the operation of the dryer will be described.                         

First, when power is applied to the dryer, the motor 17 rotates, and the heater 20 attached to the drying duct 19 is heated. In addition, the belt 11 connected to the motor shaft 21 rotates to rotate the drum 12. Then, as the drum 12 rotates, the object to be dried in the drum rotates along the inner wall of the drum and falls by its own weight when it reaches the uppermost side. Here, the object to be dried is lifted by a lift (not shown) attached to the inner wall of the drum.

On the other hand, the drying fan 18 connected to the motor shaft 21 is operated with the rotation of the motor 17, the circulating air passing through the lint filter 14 is sucked. The sucked air rises along the drying duct 19 and becomes a high temperature dry state through the heater. Then, the hot dry air absorbs the moisture present in the object to be dried while passing through the drum, resulting in a high temperature and high humidity.

In addition, the air of the high temperature and high humidity is again filtered by the lint filter 14 and then moved to a capacitor (not shown) along the circulation duct 15.

In addition, the cooling fan 16 connected to the motor shaft 21 is rotated to suck the indoor air outside the dryer. The sucked indoor air is then passed through a cooling fan 16 to the condenser.

Here, the hot and humid air moved to the capacitor along the circulation duct 15 and the indoor air sucked by the cooling fan 16 and moved to the capacitor pass through the capacitor. In addition, the hot and humid air and the indoor air are not mixed with each other by the shape of the capacitor, and only heat exchange occurs.                         

Therefore, the high temperature and high humidity air is changed to low temperature and high humidity air while losing heat to the indoor air while passing through the condenser. Then, as the temperature decreases, moisture contained in the air condenses and falls to the bottom of the condenser, and is moved to a sump (not shown) in which condensate is collected.

In addition, the water moved to the sump is moved to a condensate reservoir (not shown) located at the top of the dryer by a condensation pump.

On the other hand, the indoor air passing through the capacitor takes the heat of the high temperature and high humidity air and converts it into low temperature and high humidity air, and the temperature becomes high.

Here, the drum 12 is seated on the outer circumferential surface of the tub cover attached to the front cover back of the dryer to rotate. Therefore, there is a problem that circulating air passing through the drum may leak into a gap between the tub cover and the drum inner circumferential surface.

The present invention has been proposed to solve the above problems, to improve the sealing state between the inner circumferential surface of the drum opening and the tub cover outer circumference, to provide a drum front sealing structure of the dryer so that the circulation air does not leak to the outside The purpose.

Referring to FIG. 2, a dryer 100 having a drum front sealing structure according to the present invention includes a front cover 110, a tub cover 120 attached to a rear surface of the front cover 110, and a tub cover ( A drum 130 mounted on an outer circumferential surface of the 120 is included.

In detail, the front cover 110 and the central portion of the tub cover 120 is formed with an opening through which the object to be dried is formed. In addition, a lint filter 150 is disposed at the bottom of the opening formed in the front cover 110 to filter foreign matter contained in the circulating air passing through the drum 130 to the capacitor.

In addition, a lamp 140 illuminating the inside of the drum 130 is seated on an upper side of the inner circumferential surface of the tub cover 120, and the front cover 110 and the tub cover 120 are formed on an opening surface in contact with the tub cover 120. The gasket 121 is inserted into the gap. In addition, at least one lift 131 for attaching an object to be dried is attached to an inner circumferential surface of the drum 130.                     

Hereinafter, the functions of the above components will be described.

First, the front cover 110 forms the front portion of the dryer, and serves as a support for supporting the load of the drum. In addition, the gasket 121 is compressed by the upper edge of the door lint filter (not shown) formed on the inner circumferential surface of the door, thereby preventing the circulating air inside the drum from leaking through the door.

In addition, the lamp 140 is turned on when the door of the dryer is opened, so that the user can check the laundry collected in the drum. In addition, the lift 131 allows the laundry to rise and fall inside the drum, thereby allowing the circulating air to pass evenly through the laundry, thereby helping to dry quickly.
