Abstract
A laundry treating appliance may include a tub and a basket located at least partially within the tub and at least partially defining a laundry treating chamber. A drive system may operatively couple the tub to the basket and may be operative to rotate the basket about a rotational axis. The tub and the basket may each have a base with an effective stiffness, and the effective stiffnesses may be matched.
Claims20
A laundry treating appliance comprising:
- a tub having a tub base with a first effective stiffness;
- a basket located at least partially within the tub and at least partially defining a laundry treating chamber, the basket having a basket base with a second effective stiffness;
- and
- a drive system operatively coupling the tub to the basket and operative to rotate the basket about a rotational axis;
- wherein the first effective stiffness and the second effective stiffness are matched such that neither the tub nor the basket undergo increased relative deflection at a spin speed wherein there is a centrifugal force at an inner surface of a side wall of the basket of 1g or greater.

A laundry treating appliance comprising:
- a tub;
- a basket located at least partially within the tub and at least partially defining a laundry treating chamber;
- and
- a drive system operatively coupling the tub to the basket and operative to rotate the basket about a rotational axis;
- wherein the tub and the basket undergo substantially the same degree of deflection relative to each other when the drive system rotates the basket at a rotational speed at a spin speed near a resonance speed.
