Patent ID: 7634918

Claim:
A refrigeration device comprising: a control system for controlling a compressor of the refrigeration device, the control system being switchable among at least three states in response to user commands, the three states including a thermostat control state in which the compressor is turned on and off to maintain an interior of the refrigeration device near a target temperature, an off state in which the compressor is maintained continuously off for a first predetermined period of time, and an on state in which the compressor is maintained continuously on for a second predetermined period of time: wherein the control system comprises a control logic circuit providing a control signal for controlling a state of the compressor; a temperature detector located in the interior of the refrigeration device the temperature detector providing a temperature detector signal to the control logic circuit: a control panel including a first switch corresponding to the off state and a second switch corresponding to the on state, the first switch and the second switch providing respective signals to the control logic circuit; wherein operation of the first switch corresponding to the off state during the thermostat control state causes the control system to enter the off state for the first predetermined period of time, wherein operation of the first switch corresponding to the off state during the off state causes the control system to enter the thermostat control state, wherein operation of the second switch corresponding to the on state during the thermostat control state causes the control system to enter the on state for the second predetermined period of time, wherein operation of the second switch corresponding to the on state during the on state causes the control system to enter the thermostat control, wherein operation of the first switch corresponding to the off state during the on state causes the control system to enter the off state, and wherein operation of the second switch corresponding the on state during the off state causes the control system to enter the on state.
