There's none that I know of, but that doesn't mean there isn't. Why don't you just cover the opening from the inside(don't forget to seal the outside opening so animals don't get in.) and install a ventless over the stove hood. Or perhaps a ventless microwave. All depending on your room, of course.
If you wanted to and your were able to...you could install an outside vented fan too... more work.
