し冷蔵庫内の温度制御が行われる。In the refrigerator temperature control device configured in this way, the output of the temperature detection section 5 is supplied to the damper control section 6, and the output of the temperature detection section 5 is supplied to the damper control section 6. A close signal pulse is output when the temperature is lower than the set temperature, and an open signal pulse is output when the temperature is lower than the set temperature.Danno-1 is opened and closed by this output, and the temperature inside the refrigerator is controlled.

ス等を調整することによって騒音の発生を抑えようとし
ても、この音の発生を防止するのは不可能であった。A conventional refrigerator temperature control device is configured as described above, and the signal sent to the damper control section is a simple rectangular pulse. For this reason, when the damper 4-1 is opened and closed, it is inevitable that noise will be generated from the damper/#-1 (D fulcrum). Even if attempts were made to suppress the generation of noise by doing so, it was impossible to prevent the generation of this noise.
この考案は上記の問題に鑑みなされたもので。This idea was created in view of the above problems.
ダンパーの開閉動作による騒音の発生を防止できる冷蔵
庫の温度制御装置を得ることを目的とする。The purpose of the present invention is to obtain a temperature control device for a refrigerator that can prevent the generation of noise due to the opening/closing operation of a damper.

波形にしてダン／Ｊ−ＩＫ供給する。In FIG. 2, 8 is an NTC? connected between the input terminal and the output terminal. -Mister %9 is a capacitor connected between the output terminals on the downstream side of this NTC thermistor 8. The NTC thermistor 8 has the characteristics shown in FIG. 3, and when a current flows through the NTC thermistor 8, its resistance value decreases due to its own heat generation. Using this characteristic, the waveform shaping circuit 7 converts the rectangular pulse outputted from the control section 6 into a signal waveform with gentle rising and falling edges, and supplies it to the signal waveform.
