When I had that happen a couple of years ago, after squeezing out as much water as I could first using towels, I bought a few of these and laid them on the carpet:

Still took a good week or two to dry the carpet out fully but those silica bags seemed to help keep the humidity levels down to prevent mould growth and condensation on windows, and they probably accelerated the drying time too.
I also tried
one of these but it was pretty useless.
