Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to, and the benefit of, U.S. Provisional Application No. 62/982,189, which was filed on Feb. 27, 2020 and is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention generally relates to an improved way to clean cups and other dishware, and more specifically to a steam cleaning apparatus for kitchenware. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices and methods of manufacture.

BACKGROUND OF THE INVENTION

Cleaning a large number of cups, bottles, pots, pans, cutlery, dishware, and the like at one time can present a formidable task. Using a sink to hand wash and dry dishes requires soap, water, and other cleaning chemicals which can be expensive and time consuming. Additionally, handwashing dishes using water that is hot enough to kill bacteria and germs is not practical for hand washing as the user would easily get burned. Air drying hand washed items requires a lot of counter space leaving a cluttered kitchen.

Dishwashing machines are appliances that are designed to automate the dish washing process. These appliances clean food or liquid waste and stains attached to the dishware and cutlery by jetting or spraying a hot water and soap solution under pressure at the surface of the dishware which are retained in a water-tight tub. The water and soap are recirculated and reused saving time and energy. Once the wash cycle is complete, the dishwasher rinses the items with fresh hot water. The dishwasher completes the cleaning process by drying the items by one of several drying methods while keeping the cleaned items housed within the dishwasher and out of sight leaving an uncluttered kitchen throughout the process. Dishwashers are efficient cleaning tools that save time and resources.

While dishwashers are a significant improvement on handwashing, they still have limitations. Mechanical dishwashers clean by spraying hot water, typically heated to between 110 and 170 degrees Fahrenheit, on the items. These temperatures are not hot enough to achieve sanitization or often effective cleaning. Water must typically be heated to at least 180 degrees Fahrenheit for sanitization to occur without the addition of a chemical sanitizing solution. Moist heat in the form of saturated steam under pressure would provide more effective cleaning and sanitizing. Dishwashers are not designed to be steam cleaning only appliances.

Therefore, there is a long felt need in the art for an improved way to clean cups and other dishware, and more specifically to a steam cleaning apparatus for kitchenware. There is also a long felt need in the art for a steam cleaning apparatus that cleans and sanitizes with pressurized and saturated steam in a time efficient manner. Finally, there is a long felt need in the art for a steam cleaning apparatus that is relatively inexpensive to manufacture and both safe and easy to use.

In this manner, the improved steam cleaning apparatus of the present invention accomplishes all of the forgoing objectives, thereby providing an easy solution to clean cups, bottles, pots, pans, cutlery, and any other dishware. A primary feature of the present invention is the ability to use pressurized steam to facilitate the cleaning process. The steam cleaning apparatus of the present invention is capable of saving time and effort when cleaning dishes or kitchenware in home and commercial kitchens.
