relative motion between the vessel 306 and the walls of the vessel thus promoting cooling by transfer of heat from the liquid to the walls of the vessel the turntable 702 undergoes angular motion 704 due to its coupling to a motor 706 within the floor of the enclosure 304 although the turntable 702 is shown as circular the turntable need not be circular but could instead be oval square or rectangular since the turntable is configured to have only a limited range of back and forth angular motion in some embodiments the turntable can spin in a constant direction such as clockwise or counterclockwise in other embodiments the turntable can oscillate reversing its direction periodically in such embodiments where the turntable oscillates as an example the motor 706 can be a dc motor coupled to a controller 904 see fig9 of the countertop rapid cooler 100 so that the direction of current flow to the motor is reversed regularly thus reversing the direction of rotation of the motor it is understood that other ways to accomplish reciprocating motion 704 of the turntable 702 are within the scope of the present invention fig8 is a rear elevation view of the countertop rapid cooler 100 and refrigerator 102 of the embodiment of fig1 showing how the coolant lines 104 and 106 and the control signal cable 108 of the countertop rapid cooler are connected to the refrigerator as shown the refrigerator 102 includes two flow valves 802 804 which in this embodiment are t valves the t valves 802 and 804 operate under the control of the countertop rapid cooler through the control circuitry 806 of the refrigerator one.
