Abstract
The present invention is a drum type washing machine including an outer cabinet (1), a water tub (3) elastically supported on suspension (4A, 4B) in the outer cabinet (1), and a rotating tub (10) mounted for rotation in the water tub (3). A loading element (33) loads the suspension (4A, 4B) and has a center of gravity located between substantially the middle of a dimension from the front to the rear of the rotating tub (10) and the rear of the rotating tub (10). The loading element (33) at least includes the water tub (3), rotating tub (10), bearing assembly (14, 15, 16) and motor (17) driving the rotating tub (10).
Claims18
A drum type washing machine comprising:
- an outer cabinet;
- a water tub provided in the outer cabinet;
- a drum type rotating tub provided for rotation in the water tub, the rotating tub having a front and a rear;
- an electric motor driving the rotating tub;
- an elastic supporting element elastically supporting the water tub;
- and
- a loading element loading the supporting element and having a center of gravity located between substantially the middle of a dimension from the front to the rear of the rotating tub and the rear of the rotating tub,
- wherein the elastic supporting element includes a pair of front supporting members disposed ahead of the center of gravity of the loading element and a pair of rear supporting members disposed in the rear of the center of gravity of the loading element, and
- a distance from each front supporting member to the center of gravity of the loading element is substantially equal to a distance from each rear supporting member to the center of gravity of the loading element.
A drum type washing machine comprising:
- an outer cabinet;
- a water tub provided in the outer cabinet;
- a drum type rotating tub provided for rotation in the water tub, the rotating tub having a front and a rear;
- an electric motor driving the rotating tub;
- an elastic supporting element elastically supporting the water tub;
- and
- a loading element loading the supporting element and having a center of gravity located between substantially the middle of a dimension from the front to the rear of the rotating tub and the rear of the rotating tub,
- wherein the elastic supporting element includes a pair of front supporting members disposed ahead of the center of gravity of the loading element and a pair of rear supporting members disposed in the rear of the center of gravity of the loading element, and a distance from each front supporting member to the center of gravity of the loading element is substantially longer than a distance from each rear supporting member to the center of gravity of the loading element.
A drum type washing machine comprising:
- an outer cabinet;
- a water tub provided in the outer cabinet;
- a drum type rotating tub provided for rotation in the water tub, the rotating tub having a front and a rear;
- an electric motor driving the rotating tub;
- an elastic supporting element elastically supporting the water tub;
- and
- a loading element loading the supporting element and having a center of gravity located between substantially the middle of a dimension from the front to the rear of the rotating tub and the rear of the rotating tub,
- wherein the elastic supporting element includes a pair of the elastic supporting elements including respective portions on which the water tub is supported, the portions being located ahead of the center of gravity of the loading element between the center of gravity of the loading element and another center of gravity of the loading element in a case where an allowable maximum amount of laundry is accommodated in the rotating tub.
