The invention provides a micro household appliance comprising a refrigerating machine, a baking machine, a generator, a baking chamber, a control switch, a refrigerating chamber, temperature adjustors, a drain pipe and a water collection drum. The baking chamber and the refrigerating chamber are located in the middle and at the upper end of an enclosure respectively; the generator is fixed at the bottom end of the enclosure and is connected with the baking chamber and the refrigerating chamber through conductors; the control switch is arranged on the outer end of the enclosure; the drain pipe is connected with the bottom ends of the refrigerating chamber and the baking chamber and communicates with the water collection drum at the bottom end of the enclosure; the temperature adjustors are arranged on the baking chamber and the refrigerating chamber. The mini-refrigerating and baking machine integrates baking and refrigerating and has the dual functions of the baking and refrigerating, and thus can serve multiple purposes; the machine is small in size and occupies less space.
