Claims

[Scope of utility model registration request]

In a refrigerator-freezer in which a freezing compartment and a refrigerator compartment are respectively provided with a freezing evaporator and a refrigeration evaporator, and the refrigerant from the compressor is passed through the freezing evaporator and the refrigeration evaporator via a first pressure reducer for cooling. , a first on-off valve is arranged on the downstream side of the refrigeration evaporator, a second on-off valve and a fourth pressure reducer are arranged on the upstream side of the refrigeration evaporator, and the refrigeration evaporator and the first on-off valve are arranged on the upstream side of the refrigeration evaporator. A series connection of the second on-off valve, a second pressure reducer, and a freezing evaporator are connected in parallel to each other, and the temperature inside the refrigerator compartment is sensed to generate an on/off signal. and a second temperature controller that senses the temperature inside the freezing chamber and outputs an on/off signal, and further includes a first temperature controller that outputs an on signal of the first temperature controller and a second temperature controller that outputs an on/off signal. The AND gate established by the off signal of the temperature controller No. 2 and this AND gate.
An OR gate that is satisfied by both the output of the gate and the ON signal of the second one temperature controller, and a delay controller that delays the OFF signal of the OR gate and delays the stop of the compressor, and further A refrigerator-freezer characterized in that the first on-off valve is connected to the output of the AND gate, and the second on-off valve is connected to the output of the second temperature controller.
