Abstract

A laundry apparatus including a cabinet; a first space provided in the cabinet, in which a first treating part provided to treat laundry is installed; a second space provided in the cabinet, in which a second treating part provided to treat laundry is installed; a drawer movably provided in the second space, in which the second treating part is installed; and a rail unit configured to limit vertical and horizontal movement of the drawer with respect to the second space and to guide the outward movement of the drawer. Therefore, laundry may be treated by using the first and second treating parts and vibration and noise generated in the second treating part may be reduced.

First claim

What is claimed is:

1. A laundry apparatus comprising:
a cabinet;
a drawer movably provided in the cabinet;
a tub to hold wash water in the drawer;
a water supply pipe having a predetermined length, extending to the drawer through a rear surface of the cabinet to supply washing water to the tub;
a water drainage pipe having a predetermined length, extending to the drawer through the rear surface of the cabinet to drain the washing water from the tub; and
a water supply/drainage device provided between the cabinet and the drawer to guide the water supply pipe and the water drainage pipe,
wherein the water supply/drainage device includes a first link and a second link including an internal space,
wherein both of the water supply pipe and the water drainage pipe are provided in the internal space of the first link and the second link, and
wherein the first link and the second link are configured to be rotatably coupled to each other in a direction parallel to the withdrawal direction of drawer.

2. The laundry apparatus of claim 1 , further comprising:
a rail unit provided with a side rail unit provided on a side of the drawer to guide the vertical movement of the drawer.

3. The laundry apparatus of claim 2 , wherein the rail unit comprises a lower rail unit provided underneath a bottom of the drawer to guide the horizontal movement of the drawer.

4. The laundry apparatus of claim 2 , further comprising:
a rear lock provided between a rear surface of the drawer and a rear surface of the space to limit forward and backward movement of the drawer.

5. The laundry apparatus of claim 1 , further comprising:
a shock preventing part configured to prevent a shock generated by collision between the drawer and the cabinet when the drawer is moving inwardly.

6. The laundry apparatus of claim 1 , wherein:
the first link comprising an end rotatably connected with a rear surface of the cabinet;
the second link comprising an end rotatably connected with a rear surface of the drawer and the other end rotatably coupled to the first link; and
the water supply pipe and the water drainage pipe each have one end inserted into the first link and another end inserted into the second link.

7. The laundry apparatus of claim 1 , further comprising:
a control line configured to transmit control signal to the drawer, and
a power line configured to supply power to the drawer.

8. The laundry apparatus of claim 1 , further comprising:
a tub cover configured to open and close the tub with respect to the drawer; and
a water supplying means configured to supply wash water to a center of the tub via the tub cover.

9. The laundry apparatus of claim 1 , further comprising:
a first treating part;
a second treating part;
a first drainage pipe configured to drain wash water of the first treating part; and
a second drainage pipe configured to drain wash water of the second treating part,
wherein a maximum point of the second drainage pipe is located higher than a junction point between the first drainage pipe and the second drainage pipe.

10. The laundry apparatus of claim 1 , further comprising:
a heater sump,
wherein the heater sump is formed in a bottom of the tub to collect the wash water therein, and
wherein a sloping surface sloping toward the heater sump is formed in the bottom of the tub.

11. The laundry apparatus of claim 10 , wherein the drainage pipe is provided in a bottom of the heater sump to drain the wash water.

12. The laundry apparatus of claim 11 , further comprising:
an air chamber,
wherein the air chamber is branched toward a top of the drainage pipe and formed in the water drainage pipe; and
a pressure water level sensor,
wherein the pressure water level sensor is provided in the air chamber to detect a water level of the tub.

13. The laundry apparatus of claim 1 , further comprising:
a transit bolt securing part;
wherein the transit bolt securing part is provided in an outer surface of the tub to secure a transit bolt passing the space of the cabinet and the drawer thereto.

14. The laundry apparatus of claim 13 , further comprising:
a vibration preventing material inserted in a predetermined space formed between the tub and the drawer to limit movement of the tub.

15. The laundry apparatus of claim 1 , further comprising:
a supporting device located between an outer circumference of the tub and an inner vertical corner of the drawer to damp vertical vibration and horizontal vibration of the tub and to maintain a distance between the tub and an inside of the drawer in a predetermined range.

16. The laundry apparatus of claim 15 , wherein the supporting device comprises:
a first supporting part configured to limit downward movement and horizontal movement of the tub; and
a second supporting part configured to limit upward movement of the tub.

17. The laundry apparatus of claim 15 , wherein the supporting device comprises:
a first supporting part configured to support a horizontal load of the tub; and
a second supporting part configured to press the tub downwardly.

18. The laundry apparatus of claim 16 , wherein the first supporting part is rotatable to a predetermined angle to maintain a supporting state of the tub by using load of the tub.

19. The laundry apparatus of claim 15 , wherein the supporting device comprises:
a first fixing part provided in the tub;
a second fixing part provided in the drawer; and
a first supporting part configured to maintain a distance between the first fixing part and the second fixing part in a predetermined range.

20. The laundry apparatus of claim 19 , wherein the supporting device comprises an elastic material configured to supply an elastic force to the first and second fixing parts to maintain at least a minimum predetermined distance between the first and second fixing parts.

21. The laundry apparatus of claim 1 , further comprising:
a drainage pump provided between an inner edge of the drawer and an outer surface of the tub to drain the wash water held in the tub.

22. The laundry apparatus of claim 21 , wherein the drainage pump comprises:
a filter part configured to filter the wash water, wherein the filter part is detachable along an upward direction of the drawer; and
a pump part configured to drain the wash water, wherein the pump part is detachable from the filter part.

23. The laundry apparatus of claim 22 , wherein the pump part comprises:
a filter coupling part in which the filter part is inserted and though which the filtered wash water passes through; and
a drainage chamber configured to drain the wash water having passed through the filter coupling part.

24. The laundry apparatus of claim 23 , wherein a partition wall is formed between the filter coupling part and the drainage chamber and a through hole, in communication with the drainage chamber, is formed in the partition wall.

25. The laundry apparatus of claim 1 , further comprising:
a balancer provided in the drum to reduce eccentricity of the drum,
wherein at least a predetermined portion of the balancer forms part of an inner wall of the drum.

26. The laundry apparatus of claim 25 , wherein an inner circumferential surface of the balancer is provided along an upper surface of the drum, and wherein the inner circumferential surface of the balancer is substantially identical to an inner circumferential surface of the drum.
