I recently installed an IKEA kitchen hood, and was surprised that the power connector only had two pins (IEC C17/18). The hood has a aluminium frame (albeit painted) with metal pole switches. Can someone explain why this doesn't need to be grounded?

Perhaps the same reason toasters aren't. It is very likely that one will have two hands on the toaster when one is shocked. You have two choices: ground it, in which case the current races up one arm, through the torso, and down the other arm (frying your heart in the process). Or, keep it ungrounded and let the current race down your leg to the floor (sparing your torso and hopefully taking advantage of the fact that your shoes will provide a little more insulation that your two bare hands on metal in the first scenario.)
