Abstract

A washing machine including a first tub accommodated in a housing and formed by assembling a first member disposed in the front portion with a second member disposed in the rear portion; a second tub disposed above the first tub, a drum rotatably disposed in the inside of the second tub; and a driving shaft connected to the drum, configured to transfer a driving force to the drum and located further behind than an engaged portion of the first member and the second member of the first tub.

First claim

What is claimed is:

1. A washing machine comprising:
a first housing;
a first tub accommodated in the first housing, formed by assembling a first member disposed in a front portion thereof with a second member disposed in a rear portion thereof, and including a first opening provided in the front portion and through which laundry is put;
a second housing;
a second tub accommodated in the second housing, and including a second opening provided in an upper portion thereof and through which laundry is put;
a fixing bracket to couple the first housing and the second housing by coupling a pair of sides of the first housing with a pair of sides the second housing, respectively;
a first drum rotatably disposed in inside of the first tub;
a second drum rotatably disposed in inside of the second tub; and
a driving motor to generate a driving force to rotate the second drum;
a driving shaft connected to the second drum, and configured to transfer the generated driving force to the second drum, the driving shaft penetrating the second tub,
wherein the second tub is disposed above the first tub, and the driving shaft is located further behind than an engaged portion of the first member and the second member of the first tub, the engaged portion being where the first member and the second member are engaged together.

2. The washing machine according to claim 1 , wherein the first tub is inclined downward from the front portion to the rear portion, the engaged portion of the first tub protrudes from a side surface of the first tub, and the driving shaft protrudes below the second tub.

3. The washing machine according to claim 1 , wherein a distance from a lowermost end of the first housing to a center of a rear surface of the first drum is about 0.3 times or more of a distance from the lowermost end of the first housing to an uppermost end of the second housing.

4. The washing machine according to claim 1 , wherein a distance from a lowermost end of the first housing to a center of a rear surface of the first drum is about 0.5 times or less of a distance from the lowermost end of the first housing to an uppermost end of the second housing.

5. The washing machine according to claim 1 , wherein the second housing comprises a door configured to open or close the second opening, and
an uppermost end of the second housing is an uppermost end of the door.

6. The washing machine according to claim 1 , wherein each of the pair of sides of the first housing includes a first front end and each of the pair of sides of the second housing includes a second front end, and the fixing bracket couples the first housing with the second housing by coupling the first front end with the second front end, respectively.

7. The washing machine according to claim 6 , wherein the fixing bracket includes coupling flanges to be coupled with the first front end and the second front end, respectively by fastening members.

8. A washing machine comprising:
a first housing;
a first tub disposed in the first housing, and configured to store water;
a first drum rotatably disposed in inside of the first tub;
a second housing;
a second tub disposed above the first tub in the second housing, and configured to store water;
a second drum rotatably disposed in inside of the second tub;
a fixing bracket to couple the first housing and the second housing by coupling a pair of sides of the first housing with a pair of sides the second housing together, respectively;
a driving motor to generate a driving force to rotate the second drum; and
a driving shaft connected to the second drum, and configured to transfer the generated driving force to the second drum,
wherein the first tub is inclined downward from a front portion thereof to a rear portion thereof, and the driving shaft protrudes below the second tub.

9. The washing machine according to claim 8 , wherein the first tub is formed by assembling a first member disposed in the front portion with a second member disposed in the rear portion, and
the driving shaft is located further behind than an engaged portion of the first member and the second member of the first tub, the engaged portion being where the first member and the second member are engaged together.

10. The washing machine according to claim 8 , wherein a distance from a lowermost end of the first housing to a center of a rear surface of the first drum is about 0.3 times or more of a distance from the lowermost end of the first housing to an uppermost end of the second housing.

11. The washing machine according to claim 10 , wherein the second housing comprises a second opening through which laundry is put into the inside of the second drum, and a door configured to open or close the second opening, and
wherein the uppermost end of the second housing is the uppermost end of the door.

12. The washing machine according to claim 8 , wherein a distance from a lowermost end of the first housing to a center of a rear surface of the first drum is about 0.5 times or less of a distance from the lowermost end of the first housing to an uppermost end of the second housing.

13. The washing machine according to claim 8 , wherein each of the pair of sides of the first housing includes a first front end and each of the pair of sides of the second housing includes a second front end, and the fixing bracket couples the first housing with the second housing by coupling the first front end with the second front end, respectively.

14. The washing machine according to claim 13 , wherein the fixing bracket includes coupling flanges to be coupled with the first front end and the second front end, respectively by fastening members.

15. A washing machine comprising:
a first housing having an open upper portion;
a first tub disposed in the first housing, and configured to store water;
a first drum rotatably disposed in the first tub;
a second housing coupled with the upper portion of the first housing, the second housing having an open lower portion;
a second tub disposed in the second housing, and configured to store water;
a second drum rotatably disposed in the second tub;
a fixing bracket to couple the first housing and the second housing by coupling a pair of sides of the first housing with a pair of sides the second housing together, respectively;
a driving motor to generate a driving force to rotate the second drum; and
a driving shaft connected to the second drum, and configured to provide the generated driving force to the second drum, the driving shaft penetrating the second tub,
wherein the first housing comprises a first opening through which laundry is put into inside of the first drum from front,
the second housing comprises a second opening through which laundry is put into inside of the second drum from above,
