摘要： PROBLEM TO BE SOLVED: To perform abnormality display only when a failure actually occurs in an internal fan, and to distinguish the stop of operation caused by freezing lock from the stop caused by the failure.
SOLUTION: In a refrigerator provided with the plurality of internal fans 6 on an evaporator 4, a refrigerating cycle and all of the internal fans 6 are stopped when at least one of the internal fans 6 is stopped during a cooling operation, and a defrosting heater disposed on the evaporator 4 is brought into an on-state to heat the internal fan 6. This internal fan 6 is not rotated when the refrigerating cycle is restarted after heating for a prescribed time, and the internal fans 6 are rotated, or the abnormality is displayed only in the case of re-stop to expedite an user to repair it. Since the abnormality is displayed only when the failure actually occurs in the internal fan 6, the repair can be performed when necessary.

摘要： PROBLEM TO BE SOLVED: To control a refrigerating cycle so that a cooling operation can be quickly started after a lubricating operation, and an inside temperature can quickly approach a set temperature on the basis of the inside temperature in the cooling operation.
SOLUTION: In starting a refrigerator where a compressor is invertor-controlled, an operation is performed with rotational frequency capable of lubricating the compressor, and then performed with higher rotational frequency. Thus a suction pressure of the compressor is lowered, and the inside temperature T can quickly approach the set temperature in the cooling operation. Further the inside temperature is divided into a plurality of successive control temperature zones, the rotational frequency is increased or decreased at every time when the inside temperature is shifted among the control temperature zones, and the rotational frequency is increased or decreased when the inside temperature continuously stays in a specific control temperature zone over 10 minutes as a maximum stay time, or when the inside temperature is returned to the former control temperature zone before three minutes as a minimum stay time has passed, thus the inside temperature can quickly approach the set temperature.

摘要： PROBLEM TO BE SOLVED: To restrain a rise in storage temperature by limiting the frequency of defrosting operation to the minimum necessary. SOLUTION: An evaporator thermometer 8 is arranged in an evaporator, and when reaching predetermined standard times T2 and T3 from starting operation of a refrigerating cycle, and when starting the operation of the refrigerating cycle, the evaporator temperature is measured. When this measured result is the preset threshold temperature T D or less, a determination is made that this evaporator is frosted, and frosting is melted and eliminated by any defrosting operation of heating by a defrosting heater 9 or air-blowing of storage cold air. When the preset temperature T S in this refrigeration chamber is higher than the reference preset temperature T C , the defrosting is performed by blowing the storage cold air to the evaporator, and the frosting is eliminated by heating the defrosting heater by carrying an electric current when the preset temperature is lower than the reference preset temperature. Thus, an excessive rise in the storage temperature can be prevented by this defrosting operation by necessarily minimizing the defrosting operation. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce spike noise at switching. SOLUTION: An NPN transistor Q1 for shunt is connected, in parallel with a bias resistor R1, via a current resistor Ra to the source terminal and the gate terminal of the P-channel MOSFET transistor Tr u+ of an output circuit. A series circuit S, where the cathode terminal of a second diode Da and one end of a resistor Rb are connected with each other, is connected, in parallel with a third resistor R7, to the gate terminal of the N-channel MOSFET transistor Tr u- of the above output circuit, with the other end side of the resistor Rb as the gate terminal side of the P-channel MOSFET transistor Tr u- . By doing it this way, the discharge of the charge accumulated in the gate at turn-off of the p-channel MOSFET transistor Tr u+ is performed via a current limiting resistor Ra. On the other side, the discharge of the charge accumulated in the gate at turn-off of the N-channel MOSFET transistor Tr u- is performed via a third resistor R7, whereby it regulates di/dt of a turn-off current thereby reducing spike noise.
