BTW, cooked rice can be frozen and used later without too much loss of quality which can make a larger capacity rice cooker quite useful even if you don't have a large family.
The frozen rice should be fine for at least a month and still OK after a few months although with some loss of flavor and/or texture.
I'm single but have a 14 cup rice cooker. It was a Wirecutter budget choice. They said it makes great white rice but undercooks brown rice. I wanted it for brown rice, and addressed the undercooking by simply putting in enough rice to make 12 cups instead of 14 but filling the water to the 14 cup level so it will cook longer.
After cooking I divide it into 12 one cup plastic covered containers and into the freezer it goes.
I reheat the frozen rice by putting it in a bowl, spraying a little water on it. Enough to wet the frozen block but to not leave much loose water on the bottom of the bowl. I cover the bowl with a plate, and microwave for 3 minutes on high in a 1250 watt microwave.
Quick PSA - cooked rice needs to be refrigirated in small portions within 2 hours of cooking to avoid bacterial growth. It looks like you are aware of this, but bears repeating just in case.

I'm subbed to /r/kitchenconfidential and improperly stored leftover rice is a well-known pitfall and a major concern during kitchen health inspections.
