Abstract

A washing machine capable of increasing the washing capacity without enlarging the external appearance and also discharging a washing water during a washing operation or a spin-dry operation while completely isolated from electronic parts and thus reducing the risk of a power failure and fire, the washing machine including a body, a rotating tub rotatably disposed inside the body, a pulsator rotatably disposed inside the rotating tub, a driving part provided on a lower portion of the rotating tub to selectively rotate the rotating tub and the pulsator, a base plate to which the driving part is fixed, wherein a waterproofing member is provided between the base plate and a bottom of the body to seal the driving part and to prevent water from reaching the driving part.

Claims

1. A washing machine comprising:

a body;

a rotating tub rotatably disposed inside the body;

a pulsator rotatably disposed inside the rotating tub;

a driving part provided on a lower portion of the rotating tub to selectively rotate the rotating tub and the pulsator; and

a base plate to which the driving part is fixed,

wherein a waterproofing member is provided between the base plate and a bottom of the body to seal the driving part and to prevent water from reaching the driving part.

2. The washing machine of claim 1, wherein the waterproofing member comprises a diaphragm configured to absorb vibration of the driving part.

3. The washing machine of claim 1, wherein the waterproofing member comprises a plurality of wrinkled parts, a first fixing part extending upward from the wrinkled part, and a second fixing part extending downward from the wrinkled part.

4. The washing machine of claim 3, wherein the base plate comprises a first coupling part which is provided at a lower surface of the base plate such that the first coupling part is coupled with the first fixing part.

5. The washing machine of claim 3, further comprising a mounting part configured to support the body, wherein the mounting part comprises a bottom plate forming the bottom of the body and a second coupling part which is provided at a lower surface of the bottom plate to be coupled with the second fixing part.

6. The washing machine of claim 3, wherein the waterproofing member further comprises a wire which is provided in a form of a ring and configured to press and fix each of outer sides of the first fixing part and the second fixing part.

7. The washing machine of claim 5, wherein the mounting part further comprises a moisture infiltration preventing guide configured to prevent water from reaching a cable that is connected to one or more electronic parts of the driving part.

8. The washing machine of claim 7, the moisture infiltration preventing guide is vertically provided inside the body.

9. The washing machine of claim 5, wherein the rotating body comprises a side wall that extends from a bottom of the rotating body while being slanted with increase of a diameter, and at least one drain hole is formed in an upper end portion of the side wall.

10. The washing machine of claim 9, wherein the bottom plate is provided with a first drain port configured to discharge a washing water that is discharged through the drain hole and fallen.

11. The washing machine of claim 1, wherein:

the driving part comprises a motor, a clutch configured to selectively transfer a power of the motor to the rotating tub and the pulsator, and a flange connecting a driving shaft of the clutch to a bottom of the rotating tub, and

the flange comprises a first through-hole, which is provided in a center of the flange to allow the driving shaft to be coupled thereto, and a second through-hole, which is formed around the first through-hole in a circumferential direction of the first through-hole to pass water during a washing operation and a rinsing operation.

12. The washing machine of claim 11, wherein the based plate is provided with a second drain port configured to discharge a washing water that is discharged through the second through-hole and fallen during a washing operation or a rinsing operation.

13. The washing machine of claim 1, further comprising a suspension member connecting the base plate to a upper portion of the body, wherein the suspension member has a first end connected to at least one connecting bracket, which is provided on the base plate, and a second end connected to an upper edge of the body.

14. A washing machine comprising:

a body forming an external appearance;

a rotating tub which is rotatably installed inside the body and is provided at a lower portion thereof with a driving part;

a base plate which is connected to an upper portion of the body by at least one suspension member such that the driving part is fixed to the base plate; and

a diaphragm disposed between the base plate and a bottom of the body to seal the driving part and to absorb vibration.

15. The washing machine of claim 14, wherein the diaphragm comprises a plurality of wrinkled parts and a fixing part extending upward and downward from the wrinkled part.

16. The washing machine of claim 15, wherein the base plate comprises a coupling groove that is formed by protruding a lower surface of the base plate such that a first side of the fixing part is fixed to the base plate.

17. The washing machine of claim 15, wherein:

the bottom of the body is provided at a center thereof with an installation hole that allows the driving part to pass therethrough, and

a rim of the installation hole is bent downward such that a second side of the fixing part is fixed to the rim.

18. The washing machine of claim 15, further comprising a wire which is provided in a form of a ring and configured to press and fix an outer circumference of the fixing part.

19. The washing machine of claim 17, further comprising a moisture water infiltration preventing guide which is provided on the bottom of the body to prevent water from reaching a cable that is connected to one or more electronic parts of the driving part.
