A refrigerator includes a case body, a plurality of temperature sensors, an electrostatic atomizing device, and a control unit. There are a plurality of chambers defined in the case body. The plurality of temperature sensors are respectively disposed in the plurality of chambers. The electrostatic atomizing device is disposed in one of the chambers. The control unit is electrically connected to a cooling device, the temperature sensors, and the electrostatic atomizing device, and capable of controlling the electrostatic atomizing device to operate in an operation state or a stop sate. In the operating state, the control unit generates an upper temperature limit and a lower temperature limit according to the sensing results of the temperature sensors, and determines whether the sensing result of the temperature sensor arranged in the same chamber as the electrostatic atomizing device is greater than or equal to the upper temperature limit or smaller than the lower temperature limit. If the determination result is affirmative, the control unit controls the electrostatic atomizing device to enter the stop state.一種冰箱,包含一箱體、複數個溫度感測器、一靜電霧化裝置,及一控制單元。箱體界定出複數個腔室。該等溫度感測器分別設置於該等腔室內。靜電霧化裝置設置於其中一腔室內。控制單元電連接於冷卻裝置、溫度感測器及靜電霧化裝置,且能控制靜電霧化裝置操作於一運轉狀態及一停止狀態。於運轉狀態下,控制單元根據該等溫度感測器的感測結果產生一溫度上限及一溫度下限,且判斷與靜電霧化裝置設置於同一腔室的溫度感測器的感測結果是否大於等於溫度上限或小於等於溫度下限,若是,則控制靜電霧化裝置進入停止狀態。100‧‧‧冰箱2、2a、2b、2c‧‧‧溫度感測器3‧‧‧靜電霧化裝置4‧‧‧冷卻裝置5‧‧‧風扇6‧‧‧電子風門7‧‧‧控制單元SP‧‧‧電源控制訊號SC1‧‧‧第一功率控制訊號SC2‧‧‧第二功率控制訊號SF‧‧‧回授電壓訊號
