  • Patent number: 6741183
    Abstract: A pre-injury contact warning device for a front door of an automatic dishwasher or oven, the front door being openable to a generally horizontal very low position above the floor. In one embodiment, the device includes a housing attachable to a surface of the front door. A warning signal emitter sensorially perceptible by a person receives electric power from a miniature storage battery mounted within the housing. An angle-sensitive switch mounted in the housing is operably interconnected between the warning signal emitter and a proximity sensor. The switch is open and the proximity sensor and the warning signal emitter off when the front door is closed, while the switch is closed and the warning signal emitter is armed and on standby when the front door is open. When a person gets within a predetermined distance from the open door, the proximity sensor activates the warning signal emitter.

The switch is open and the warning signal emitter off when the front door is closed, while the switch is closed and the warning emitter on when the front door is open. The warning signal emitter, when on, is sufficiently sensorially perceivable to warn or alert the person nearby the dishwasher that the front door is open and to be avoided. Other embodiments are provided which are operatively dependent upon other forms of sensory perception, e.g.

  • Patent number: 6295004
    Abstract: A warning light device attachable to, or as a permanent part of, a front door of an automatic dishwasher or oven, the front door being openable to a generally horizontal very low position above the floor. In one embodiment, the device includes a housing attachable to a surface of the front door. A warning light mounted on the housing receives electric power from a miniature storage battery mounted within the housing. An angle-sensitive switch mounted in the housing is operably interconnected between the warning light and the storage battery. The switch is open and the warning light off when the front door is closed, while the switch is closed and the warning light on when the front door is open. The warning light, when on, is sufficiently visible to warn or alert a person nearby the dishwasher that the front door is open and to be avoided. This invention may also be embodied in such appliances at time of manufacture.
