1. A method of retracting a dishwasher rack towards a stowed position within a dish washing appliance comprising the steps of:
providing a dishwasher rack having one or more torsion springs positioned within one or more gearboxes;
positioning the dishwasher rack from a stowed position to one or more deployed positions;
increasing the tension force of the one or more torsion springs when positioning the dishwasher rack from the stowed position towards the one or more deployed positions; and
automatically retracting the dishwasher rack from the one or more deployed positions towards the stowed position.
2. The method of claim 1 further comprising the step of dampening the retracting of the dishwasher rack from the one or more deployed positions towards the stowed position.
3. The method of claim 1 further comprising the step of locking the dishwasher rack in the one or more deployed positions.
4. The method of claim 3 further comprising the step of unlocking the dishwasher rack from the one or more deployed positions.
5. The method of claim 1 wherein the dishwasher rack includes one or more geared elongated shafts rotationally engaging one or more rails with corresponding geared teeth.
6. The method of claim 5 wherein the step of automatically retracting the dishwasher rack includes the one or more torsion springs rotating the one or more geared elongated shafts along the one or more rails.
7. The method of claim 1 further comprising the step of draining the one or more gearboxes.
8. The method of claim 1 wherein the one or more gearboxes is sealed.
9. A method of retracting a dishwasher rack towards a stowed position within a dish washing appliance comprising the steps of:
providing a dishwasher rack having at least one basket, one or more elongated shafts connected to the at least one basket having one or more geared wheels fixed to the one or more shafts, and one or more torsion springs secured to the one or more elongated shafts and positioned in one or more gearboxes, and wherein the one or more geared wheels rotationally engage one or more rails with corresponding geared teeth;
positioning the dishwasher rack from a stowed position to one or more deployed positions;
increasing the tension force of the one or more torsion springs when positioning the dishwasher rack from the stowed position towards the one or more deployed positions; and
automatically retracting the dishwasher rack from the one or more deployed positions towards the stowed position.
10. The method of claim 9 further comprising the step of dampening the retracting of the dishwasher rack from the one or more deployed positions towards the stowed position.
11. The method of claim 10 wherein the dishwasher rack includes a damper to dampen the translation of the dishwasher rack.
12. The method of claim 11 wherein the damper is positioned within the one or more gearboxes.
13. The method of claim 9 further comprising the step of locking the dishwasher rack in the one or more deployed positions.
14. The method of claim 9 further comprising the step of unlocking the dishwasher rack from the one or more deployed positions.
15. The method of claim 9 wherein the dishwasher rack is an upper dishwasher rack.
16. The method of claim 9 wherein the one or more torsion springs are a spiral spring.
17. A method of retracting a dishwasher rack towards a stowed position within a dish washing appliance comprising the steps of:
providing a dishwasher rack having one or more torsion springs positioned within one or more gearboxes;
positioning the dishwasher rack from a stowed position to one or more deployed positions;
retracting the dishwasher rack from the one or more deployed positions towards the stowed position; and
dampening the retracting of the dishwasher rack from the one or more deployed positions towards the stowed position.
18. The method of claim 17 further comprising the step of locking the dishwasher rack in the one or more deployed positions.
19. The method of claim 17 further comprising the step of unlocking the dishwasher rack from the one or more deployed positions.
20. The method of claim 17 further comprising the step of increasing the tension force of the one or more torsion springs when positioning the dishwasher rack towards the one or more deployed positions.
21. The method of claim 20 wherein the step of retracting the dishwasher rack includes the one or more torsion springs rotating one or more geared elongated shafts along one or more rails.
22. The method of claim 17 wherein the step of dampening may retract the dishwasher rack at one or more speed values.
