Washing Machine Door Cone Geometry to Keep Laundry Out of the Gap

The patent introduces a laundry deflector as an intermediary component positioned between the drum and the stationary sleeve. This deflector fills the annular gap and actively redirects laundry items away from the gap area, preventing direct contact between laundry and the sleeve. The deflector serves as a mediator that resolves the contradiction by maintaining the necessary distance for vibration clearance while simultaneously blocking the harmful path of laundry items that would otherwise cause friction damage.

The patent converts the potentially harmful frictional contact between laundry and the stationary sleeve into a beneficial deflection mechanism. By positioning the laundry deflector to interact with laundry items in the annular gap, the harmful rubbing action is transformed into a controlled deflection that redirects laundry away from the damage zone. The friction that would otherwise be destructive is harnessed to push laundry against the deflector surface, which then guides it safely back into the drum interior.

The patent changes the geometric parameters of the filling body by introducing a crescent-shaped indentation on its lateral surface. This modification creates a sliding surface with optimized orientation that reduces the friction coefficient between the laundry and the deflector surface. The indentation geometry is specifically designed to guide laundry items smoothly back into the drum interior, minimizing resistive friction forces while maintaining effective prevention of laundry penetration into the harmful annular gap.

The patent applies local quality modification by creating a specific crescent-shaped indentation only in the critical area where laundry deflection is needed. This localized geometric feature provides enhanced sliding properties precisely where laundry items contact the filling body, while leaving other areas of the filling body unchanged. The local modification optimizes the interaction between laundry and deflector surface, reducing friction damage in the critical zone without affecting the overall structure.

The laundry deflector acts as a protective intermediary that becomes increasingly important when the drum is filled to maximum capacity. With more laundry items present, the probability of items entering the annular gap and causing jams increases. The deflector continuously monitors and redirects laundry items, preventing them from penetrating into the gap area where jams would occur. This intermediary protection system enables safe operation at maximum filling capacity without compromising reliability.

The patent implements preliminary anti-action by proactively preventing laundry items from entering the harmful annular gap before jamming can occur. The laundry deflector is positioned and shaped to intercept laundry items early in their potential harmful path, redirecting them back into the drum interior before they can reach the gap between the drum and stationary sleeve. This preliminary intervention prevents the development of jamming conditions even when the drum is filled to maximum capacity.
