Abstract
A spring device for spring-mounting a laundry drum of a washing machine has at least one spring means and coupling means for coupling the spring means to the spring device. The spring means has a spring constant or spring properties which are temperature-dependent and can be varied by a temperature effect on the spring means. As an alternative or in addition, the coupling means are designed in a temperature-dependent manner in such a way that they vary their coupling effect between the spring means and the spring device by a temperature effect. Heating means are provided for the spring means and/or for the coupling means in order to warm up the said spring means and/or coupling means and to change their spring properties or their coupling effect. Therefore, the spring-mounting arrangement of the laundry drum can be thermally, and therefore quickly and simply, varied.
