Abstract
A laundry treatment apparatus includes a casing, an outer tub suspended in the casing, and a pair of horizontal vibration buffering devices arranged to form opposite angles relative each other in the casing, the horizontal vibration buffering devices each coupling a predetermined support disposed outside the outer tub with the outer tub and each having a portion connected with the outer tub to be displaced relative a portion connected with the predetermined support as the outer tub vibrates, where the pair of horizontal vibration buffering devices each provide an attenuation force according to the displacement.
Claims21
A laundry treatment apparatus, comprising:
- a casing;
- an outer tub suspended in the casing;
- a pair of supporting rods respectively coupling opposite corners of the casing with a lower part of the outer tub;
- and
- a pair of horizontal vibration buffering devices arranged to form opposite angles relative each other in the casing, the horizontal vibration buffering devices each coupling the supporting rod and each having a portion coupled with the outer tub to be displaced relative a portion coupled with the supporting rod as the outer tub vibrates,
- wherein the pair of horizontal vibration buffering devices each provide an attenuation force according to the displacement, and
- wherein, for each horizontal vibration buffering device, a virtual line from the portion coupled with the outer tub to the portion coupled with the supporting rod forms an acute angle with respect to a tangent of a circumference of the outer tub in a stationary state, at a position where the horizontal vibration buffering devices is connected,
- wherein the portion coupled with the outer tub is rotatable about a substantially vertical axis.
A laundry treatment apparatus, comprising:
- a casing;
- an outer tub suspended in the casing;
- four supporting rods respectively coupling four corners of the casing with a lower part of the outer tub;
- and
- four horizontal vibration buffering devices,
- wherein a pair of the horizontal vibration buffering devices are arranged in the casing to face another pair of the horizontal vibration buffering devices to form opposite angles relative each other, each of the horizontal vibration buffering devices coupling the supporting rod with the outer tub,
- wherein a portion of each horizontal vibration buffering device connected with the outer tub relative a portion of each horizontal vibration buffering device connected with the supporting rod has a displacement as the outer tub vibrates,
- wherein each of the four horizontal vibration buffering devices provides an attenuation force according to the displacement, and
- wherein, for each horizontal vibration buffering device, a virtual line from the portion coupled with the outer tub to the portion coupled with the supporting rod forms an acute angle with respect to a tangent of a circumference of the outer tub in a stationary state, at a position where the horizontal vibration buffering devices is connected,
- wherein the portion coupled with the outer tub is rotatable about a substantially vertical axis.
