Oh, I'm glad I don't work in the oven business. We're just starting a stealth startup that's revolutionizing dishwashers, and the prototypes are amazing. They use less water, less detergent, and this weekend we're hoping to solve the last remaining issue: occasionally, they break glasses.
It sounds like you're joking, but I've long dreamed of a different type of dishwasher. One that washes instantly. I don't need it to fit more than a single plate at one time. Just put something in from one end, and out comes clean and dry plate on the other end. Like a car wash. I am quite certain these exist already large kitchens and I seem to remember one from a school diner from maybe 35 years ago, but I've alway…
Because they need space, they need even more nasty chemicals than domestic dishwashers, they need a stack of trays to load the dishes on and a crew to load and unload them.
If you want a dishwasher which doesn't require unloading after use you can get 2 of them, one of which is "clean", the other "dirty" or washing. When the "dirty" one is full you turn it on and let it wash while you take whatever you need from the "clean" one. Once the formerly-dirty one has finished it's cycle the roles are reversed and it becomes the "clean" one.
