Whenever a fridge door is opened, cold air flows out and warm air flows in; the more often the door is opened, the more heat has to be pumped out again.
Why not have a fridge (or freezer for that matter) built like a glovebox ? Anyone who's ever handled biohazard materials, dangerous chemicals or nuclides will be familar with these; a double walled enclosure with a pair of thick flexible gloves protruding through.
Add a small "airlock" hatch and items can be passed into or out of the enclosure with the minimum exchange of outside air, thus reducing the requirement for cooling.-- 8th of 7, Dec 03 2007 fridge_20belly grabs opportunity to promote one of own favs [xenzag, Dec 03 2007] o.k.

I'm always amazed at the bio-hazardous things that grow in the cold and dark. Anything that makes handling it a bit safer gets an automatic bun.-- DenholmRicshaw, Dec 03 2007 Baked I'm afraid, my cousin has one (it also dispenses ice and 2 chilled drinks). The result is that almost every item in the fridge is crammed into the easy access area.-- marklar, Dec 04 2007 My glovebox gets chilled when the Aircon is active - does that count?-- gnomethang, Dec 04 2007 Ohhhh.. Okay.. I thought this was an idea to make you car's glove-box into a fridge. This is much more complicated, almost over-complicated; BUN-- evilpenguin, Dec 05 2007 random, halfbakery
