    • In a refrigerator, the inner space of a heat insulated housing is divided to form a refrigerating compartment, a freezer compartment, and a vegetable compartment. A projection which contacts with the back of a cooler cover and divides the space behind the cooler cover into two chambers arranged in a lateral direction is formed on a back wall portion. The space enclosed by the projection, the cooler cover, and the housing is formed as a cold air passage for guiding cold air of the refrigerating compartment to the vegetable compartment. A damper device has a shutter plate, a bias spring which urges the shutter plate toward a cold air duct, and a shape memorizing alloy coil spring on which a heater is wound. A weak current is always supplied from a damper control device to the heater so that the temperature of the shape memorizing alloy coil spring is maintained at the Ms point (martensite phase transition start temperature) or higher under the state where the shutter plate is lifted up. A defrosting control device for controlling the electric power supply to a defrosting heater has an operation integrating counter for integrating the operation time period of a compressor, converting means for converting the open/close frequency of doors into a time period, and a door-closure counter for measuring a time period of a door-closure state.
    • 在冰箱中,绝热壳体的内部空间被分割成冷藏室,冷冻室和蔬菜室。 在后壁部分上形成有与冷却器盖的背面接触并将冷却器盖后面的空间分成两个沿横向布置的两个室的突起。 由突起,冷却器盖和壳体包围的空间形成为用于将冷藏室的冷空气引导到蔬菜室的冷气通道。 阻尼器装置具有挡板,将挡板朝向冷风管道推压的偏置弹簧,以及在其上缠绕加热器的形状记忆合金螺旋弹簧。 总是从阻尼器控制装置向加热器提供弱电流,使得形状记忆合金螺旋弹簧的温度在快门板被提升的状态下保持在Ms点(马氏体相变开始温度)或更高温度 。 用于控制对除霜加热器的电力供应的除霜控制装置具有用于对压缩机的运转时间进行积分的运算积分计数器,将门的开/关频率转换为时间段的转换装置和门关闭 用于测量门关闭状态的时间段的计数器。
