The present invention relates to a drainage apparatus for a washing machine, and more particularly, to a drainage apparatus for a washing machine, in which a valve plate that opens and closes a valve housing is directly connected to a pulling member and a heater member is installed inside the valve housing to prevent freezing, To a drainage device.

Generally, as shown in FIG. 1, a washing machine is provided with a washing tub 3 in which a water tub 2, in which wash water is drained, is suspended and a laundry is contained in a water tub 2, do. A power switching member 5 for rotating the pulsator 4 in the forward and reverse directions and rotating the washing tub 3 at the time of dewatering is provided in the water tub 2, Lt; / RTI > Further, the power switching member 5 is connected to the motor 6 via the belt 6a.

When the laundry is placed in the washing tub 3 and the wash water is supplied, the power switching member 5 is rotated by the driving of the motor 6. At this time, the power switching member (5) rotates the pulsator (4) in normal and reverse direction during washing to cause water flow, and at the time of dewatering, the washing tub (3) is rotated at high speed to dewater laundry.

Further, in the dehydration, water in the water tank 2 is drained, and dehydration proceeds. 2 is a sectional view of a conventional drainage apparatus in which a valve plate 8a is provided in a valve housing 8 having an inlet 8b connected to a drain port 7 on the bottom of the water tank 2, And is sealed by the cap 8h which is defective as one side.

A traction rod 8e having an end connected to the valve plate 8a is provided at the center of the cap 8h and a traction rod 8e is moved by a spring 8f coupled to the outer periphery, Thereby sealing the inlet 8b. The valve plate 8a is engaged with the bellows 8d having elasticity and the bellows 8d is fixed with the cap 8h.

In the conventional drainage apparatus constructed as described above, when the valve plate 8a is moved by the spring 8f, the inlet 8b is closed and the washing water is not drained toward the outlet 8c. In this state, when the motor or the solenoid in the pulling portion 9 connected to the pulling rod 8e is operated, the pulling rod 8e is pulled to one side. At this time, the valve plate 8a is opened and the washing water is drained along the inlet 8b and the outlet 8c.

The pulling member 8 and the pulling rod 8e are connected to each other through the spring 8g so that the pulling rod 8e is pulled by the tension of the spring 8g during operation of the pulling member 9, When this tension is weakened, it is not pulled well. In addition, when the inside of the valve housing 8 is freezed in winter, the valve plate 8a sticks to the inlet 8b, and the inlet 8b is completely sealed.

SUMMARY OF THE INVENTION The present invention has been developed in consideration of the conventional problems, and an object of the present invention is to provide a valve seat in which a valve plate in a valve housing is directly connected to a pulling member and a heater member is mounted in a valve housing to prevent freezing, And a drainage device for the washing machine.

According to an aspect of the present invention, there is provided a washing machine comprising: a water tank enclosing a washing tub provided with pulsators; A valve housing connected to a drain port formed on the bottom of the water tank and opened and closed by a valve plate installed therein; A pulling member for directly pulling the pulling rod connected to the valve plate; And a heater member incorporated in one side of the valve housing.

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

FIG. 3 is a cross-sectional view of a drainage apparatus according to the present invention, wherein like reference numerals are used to designate the same components as in the first embodiment.

An inlet (11) of the valve housing (10) is coupled to a drain hole (7) formed in the bottom of the water tank (2). The valve housing 10 is fitted with a valve plate 12 so that the inlet 11 is sealed and the valve plate 12 is connected to the bellows 13 having elasticity. The bellows 13 is also coupled to one side of the valve housing 10 by a cap 18.

The valve plate 12 is coupled to the rear end of the traction rod 15 which is moved to the center of the cap 18 and the lever 21 of the traction member 20 is connected to the tip of the traction rod 15, Lt; / RTI >

Further, the valve housing 10 has an outlet 14 formed at the lower end of the bellows 13, so that when the valve plate 12 is opened,

And is drained to the outside through the opening 11 and the outlet 14. [ A heater member (30) is provided in the vicinity of the inlet (11). The heater member 30 is fitted into the hole 17 formed at one side of the inlet 11 through the heat insulating material 31 and is fixed by the cap 32.

In the present invention constructed as described above, the pull rod 15 is movably fitted in the center of the cap 18 coupled to one side of the valve housing 10, and the valve plate 12 is coupled to the rear end of the pull rod 15. The lever 21 of the pulling member 20 is connected to the tip of the pulling rod 15 by the pin 22 so that the pulling rod 15 is pulled through the lever 21 when the pulling member 20 is operated. Further, the heater member (30) is coupled to the valve housing (10) in the vicinity of the inlet (11) to prevent freezing.

The washing and draining processes according to the present invention are as follows. During washing, water is generated in accordance with forward and reverse rotation of the pulsator 4, and washing is performed. When the valve plate 12 is opened during dewatering, wash water is drained. That is, when the pulling member 20 is operated, the lever 21 is pulled and the pulling rod 15 is pulled together.

In this process, the bellows 13 is contracted and the valve plate 12 is moved to open the inlet 11. At this time, the spring 16 is maintained in a compressed state, and at the opening of the inlet 11, the wash water is drained to the outside along the inlet 11 and the outlet 14. On the other hand, when drainage is completed, the operation of the pulling member 20 is stopped and the compressed spring 16 is restored, so that the valve plate 12 is moved and the inlet 11 is closed. Meanwhile, the heater member 30 installed in the valve housing 10 is operated during the operation of the washing machine in winter to prevent the valve housing 10 from freezing. Therefore, the washing water drains smoothly.

As described above, according to the present invention, the valve plate inside the valve housing is connected to the pull rod 15 and the pull rod is directly connected to the lever of the pull member, so that the pulling force of the valve plate is improved and the opening and closing operation of the valve plate is smooth. In addition, since the heater member is mounted inside the valve housing, it is possible to prevent freezing in winter and to improve the opening and closing performance and drainage of the valve plate.
