Claims19
A combination washer dryer, comprising:
- an outer drum;
- a rotatable cylindrical variable size inner drum arranged coaxially within the outer drum having a moveable wall disposed between a front end of the inner drum and a rear end of the inner drum such that an amount of clothes is holdable within a portion of the inner drum defined between the front end of the inner drum and the moveable wall, the moveable wall moveable from a first position ascertainable during a wash cycle of the combination washer dryer to a second position ascertainable during a heat dry cycle of the combination washer dryer, and wherein a range of motion of the moveable wall from the first position to the second position is effective to increase a size of the inner drum portion that holds the clothes;
- a water handling system adapted to intake water into the inner or outer drum and to remove water from the inner or outer drum;
- an air handling system adapted to intake air into the inner or outer drum and to remove air from the inner or outer drum;
- and
- a control system adapted to control the movement of the moveable wall.
A combined washer dryer adapted to sequentially wash and dry clothes, comprising:
- a housing that houses the combination washer dryer and has a door arranged on a front section of the combination washer dryer for direct ingress and egress of clothes;
- a variable size drum that increases in size between a wash cycle and a subsequent heat dry cycle by a size increasing element that is moveable from a first position ascertainable during a wash cycle of the combination washer dryer to a second position ascertainable during a heat dry cycle of the combination washer dryer, wherein a range of motion of the size increasing element from the first position to the second position is effective to increase a size of at least a portion of the inner drum that holds the clothes;
- and
- a controller that controls the increase in size of the variable size drum.
A variable size drum adapted for use in a combination washer dryer, comprising:
- a rotatable cylindrical chamber adapted to hold an amount of clothes and having a plurality of holes extending through the chamber and arranged toward an end of the inner drum to allow air or water to pass between the inner drum and the outer drum;
- and
- an element arranged within or in unity with or connected to the chamber that is movable from a first position during a wash cycle of the combination washer dryer to a second position during a dry cycle of the combination washer dryer,
- whereby when the element is moved from the first position to the second position the volume of the variable size drum that holds the clothes is increased.
