Abstract: A transportation-robust bi-stable latch mechanism preserves low actuation forces by means of an auxiliary mechanism blocking the effects of shock forces during transportation.

Abstract: A magnetic lid closure sensor uses a magnet sensor element mounted within the washing machine housing below the closed lid. Flux directors conduct flux from a magnet in the lid to the magnet sensor. A lock mechanism employs a hook engaging an aperture in the lid so that opening of the lid does not impart a torque to the hook such as would disengage it, allowing the hook to be activated and deactivated with a simple bi-directional solenoid.

Abstract: A dishwasher provides forced air flow in a counter-convectional direction so as to exhaust air out of a bottom portion of the washing volume in contrast to normal convective air flow.

Abstract: An electrically operable door latch employs a permanent magnet for retaining an appliance door closed against the force of a resilient seal. An electromagnet bucks the magnetic attraction of the permanent magnet allowing the latch to be electronically releasable. A simple mechanism and inherent force limits are obtained by a direct magnetic attraction between a strike plate and the latch, one on the door and one on the housing.

Abstract: An appliance door latch provides a rotating hook supported on a linear carriage that may move along a line toward and away from a strike. A release of the strike from the rotating hook requires a compression of springs biasing the linear carriage which are then retained in a compressed state by a catch surface on the rotating hook. Re-engagement of the strike with the rotating hook releases the catch surface, causing the springs to pull the rotating hook and strike inward to aid in compressing a door gasket or the like.

Abstract: A fast engage, slow release electrical actuator combines an electromagnetic actuator with a thermal actuator, the latter which retains the electromagnetic actuator after the former has been actuated to delay the release thereof.
