DVC Resorts include Bay Lake Tower, Boulder Ridge Villas, Copper Creek Villas, Villas at Grand Floridian, Polynesian Resort and Villas (only the bungalows would fit your criteria here), Beach Club Villas, Boardwalk Villas, Saratoga Springs, Old Key West, Riviera Resort. All of their 2-bedroom villas will include a full kitchen plus washer/dryer.
All of the deluxe resorts (except Wilderness Lodge) have two-bedroom suites that include club level access, but they are typically more expensive than the villas and do not have a kitchen or washer/dryer. You typically have to call into WDW reservations to book the 2-bedroom suites at the resorts.
You can also find two-bedroom suites at Coronado Springs, plus "suites" with two separate sleeping areas at Art of Animation and All-Star Music. A cabin at Ft. W would also offer you two separate sleeping spaces.
If you don't mind not having Magical Express or 180+10 ADR privileges, both the Swan and Dolphin offer 2-bedroom suites. Depending on the time of year, you can sometimes book these suites around the same price per night as a standard room at a WDW deluxe. You need to call Swan/Dolphin directly to book these suites.
