Description

本開示に係る冷蔵庫は、冷蔵温度帯に設定される冷蔵室と、冷凍温度帯に設定される冷凍室と、冷蔵温度帯から冷凍温度帯までの範囲で設定温度を切り替え可能な温度切替室と、空気を冷却する冷却器と、冷却器で冷却された空気を冷蔵室、冷凍室および温度切替室へ送風する送風機と、を収容する冷却器室と、冷却器室において冷却器に対向しかつ空気の流れ方向に対して互いに異なる位置に開口する温度切替室戻り口を各々有し、温度切替室内の空気を冷却器室へ導く複数の温度切替室戻り風路と、が設けられた本体部と、温度切替室内の空気が冷却器室へ戻る風路を、複数の温度切替室戻り風路のうちのいずれか１つに切り替える風路切替手段と、温度切替室の設定温度と測定された温度切替室の室内温度との少なくとも一方に基づく基準温度に基づいて、風路切替手段に温度切替室戻り風路を切り替えさせる制御を行う制御装置と、を備えるものである。 The refrigerator according to the present disclosure includes a refrigerating chamber set in the refrigerating temperature zone, a freezing chamber set in the refrigerating temperature zone, and a temperature switching chamber in which the set temperature can be switched in the range from the refrigerating temperature zone to the refrigerating temperature zone. A cooler room that houses a cooler that cools the air and a blower that blows the air cooled by the cooler to the refrigerating room, the freezing room, and the temperature switching room, and the cooler room facing the cooler. The main body is provided with a plurality of temperature switching chamber return ports that have temperature switching chamber return ports that open at different positions with respect to the air flow direction and guide the air in the temperature switching chamber to the cooler chamber. It is measured as the air passage switching means for switching the air passage for the air in the temperature switching chamber to return to the cooler chamber to any one of a plurality of temperature switching chamber return air passages, and the set temperature of the temperature switching chamber. It is provided with a control device that controls the air passage switching means to switch the return air passage of the temperature switching chamber based on the reference temperature based on at least one of the indoor temperature of the temperature switching chamber.
