## 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.

## Claims

### Claim 1

A warning light device attachable to a front door of an automatic dishwasher, the front door being openable to a generally horizontal position above a support surface of the dishwasher, said device comprising:
a housing attachable to a surface of the front door;
a warning light mounted on said housing and a miniature storage battery mounted within said housing;
an angle-sensitive switch mounted in said housing and operably interconnected between said warning light and said storage battery, said switch being open and said warning light off when the front door is closed, said switch being closed and said warning light on when the front door is open;
said warning light, when on, being sufficiently visible to warn or alert a person nearby the dishwasher that the front door is open and to be avoided.

### Claim 2 (depends on 1)

A warning light device as set forth in claim 1, wherein:
said housing is sized for attachment to a distal corner inner surface of the front door with said warning light being upwardly aimed for enhanced visibility when the front door is open.

### Claim 3 (depends on 1)

A warning light device as set forth in claim 1, wherein:
said housing includes flat opposing reflective surfaces which extend divergently from said warning light for visually enhancing and focusing light emitting from said warning light.

### Claim 4

In combination, dishwasher and warning light device positioned on a surface of a front door of said dishwasher, said front door openable during loading and emptying of said dishwasher to a generally horizontal position at a predetermined height above the floor, said warning light device comprising:
a warning light attached to a surface of the front door;
a front door angle-sensitive switch operably interconnected between said warning light and a power source, said switch being open and said warning light off when the front door is closed, said switch being closed and said warning light on when the front door is open;
said warning light, when on, being sufficiently visible to serve as a visible warning to a person near to the dishwasher of a potential for leg injury due to impact with a margin of the open front door.

### Claim 5 (depends on 4)

A warning light device as set forth in claim 4, wherein:
