Description

CROSS-REFERENCE

This application claims priority from Provisional Patent Application Ser. No. 61/816,475 filed on Apr. 26, 2013.

FIELD OF THE INVENTION

This invention relates to a dishwasher monitoring device that can be easily and removably attached to the front face of a dishwasher and used to indicate to a user whether the contents of the dishwasher are clean or dirty. The invention prevents users from accidentally unloading rinsed dishes that have not yet been properly cleaned by the dishwasher, as well as loading dirty dishes into a dishwasher that has completed the washing cycle and which currently contains clean dishes, drink ware, pots pans and the like.

BACKGROUND

Many individuals who use a dishwasher to wash dirty plates, pots, pans, drinkware, tableware, utensils and the like have inadvertently made the mistake of combining dirty items with clean items or vice versa. Much of the confusion tends to arise around whether the contents of the dishwasher are clean or dirty. More specifically, it can be difficult for individuals to determine whether the contents of a dishwasher have been washed or merely rinsed. As a result, some individuals may remove dirty dishes from a dishwasher and use the same because the user believes that the item has been cleaned. This practice is not only unsanitary, but can result in the spread of germs, food-born illnesses and even death. Other individuals may add dirty dishes, drink ware, etc. to a dishwasher with clean contents (not realizing that the contents had already been properly washed) and run the dishwasher for a second time, which is inefficient and waste electricity, water and detergent.

Consequently, there exists in the art a long-felt need for a dishwasher monitor device that indicates to a user whether the contents of the dishwasher are clean or dirty. There also exists in the art a long felt need for a dishwasher monitor device that can be easily and removably attached to the front panel of a dishwasher, and which does not require an external power source (such as electricity, natural gas, etc.) to operate. Finally, there is a long-felt need for a dishwasher monitoring device that accomplishes all of the forgoing objectives, and that is relatively inexpensive to manufacture, and safe and easy to use.
