The present invention relates to a dryer, and more particularly, to a motor supporter assembly structure of a dryer such that a cushion inserted in a motor supporter connected to the motor shaft to support the motor does not rotate together as the motor shaft rotates.

In general, a drum type dryer is a device that blows hot air generated by an electric heater or a gas combustion device into a drum to absorb moisture remaining in a drying object and to dry the drying object.

1 is a cross-sectional view schematically showing a general condensing drum dryer, Figure 2 is an enlarged perspective view showing a base portion in which a motor is provided.

1 and 2, the condensation-type drum dryer includes a cabinet 10 forming an external appearance, a cylindrical drum 12 formed inside the cabinet 10, and opening and closing the drum 12. The door 13 to adjust the, and the belt 11 surrounding the outer peripheral surface of the drum 12 is included.

In addition, the cooling fan side motor shaft 52 connected to the belt 11, the drying fan side motor shaft 21 connected to the motor 17 on the opposite side of the cooling fan side motor shaft 52, and the motor shaft ( 21 and 52 are connected to the motor 17 to provide a rotational force, and connected to the cooling fan side motor shaft 52 and rotates under the rotational force of the motor 17 to suck the indoor air through the blower 31 Cooling fan 16 is included.

In detail, the belt 11 spans the outer circumferential surface of the pulley 53 connected to the shaft extending on the rear side of the motor, so that the belt 11 is in close contact with the outer circumferential surface of the drum 12.

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

In addition, a lint filter 14 formed below the opening through which the door 13 is inserted to filter foreign matter 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. Then, the drum 12 is rotated while the belt 11 connected to the cooling fan side motor shaft 52 rotates. 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 drying fan side motor shaft 21 is operated together with the rotation of the motor 17, so that the circulating air passing through the lint filter 14 is sucked. The sucked air rises along the drying duct 19 to be in 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.

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 motor is mounted on the base and supported by the motor supporter 50 connected to the motor shaft. The motor supporter 50 is coupled to the base by at least one fastening member 51.

In addition, the upper portion of the motor supporter 50 is inserted into the cushion for absorbing the vibration and shock transmitted from the motor.

Here, a problem arises in which the cushion rotates together with the motor shaft. As described above, as the motor shaft and the cushion rotate together, the cushion may be separated from the motor supporter.

The present invention has been proposed to solve the above problems, by providing a rigid support in the motor supporter assembly structure to be fixed to the motor supporter irrespective of the rotation of the motor shaft, thereby providing a motor supporter assembly structure of the dryer For the purpose of

Motor supporter assembly structure of the dryer according to the present invention for achieving the object as described above the base; A motor supporter supporting the motor shaft; And a motor supporter accommodating part formed at one side of the base to insert and seat the motor supporter, wherein the motor supporter is formed at a lower portion of the supporter body, and a guide rib for inserting a guide rib into the lower part. Inserts and cushions for absorbing the vibration and shock generated from the motor seated on the upper portion.

By the above configuration, there is no need to remove the drum from the dryer in order to repair the inside of the motor, there is an effect that the motor is easily separated by rotating the motor supporter to push in the opposite direction along the motor axis.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
