    • A refrigerating unit comprising an adiabatic box provided with a door to its opening, a machine compartment in contact with said adiabatic box, and a refrigerating cycle wherein the machine compartment is covered with a damping plate and is attached to the adiabatic box with a jointing means so as to be sealed, and further said refrigerating unit comprises an oil cooler for cooling lubricating oil in a compressor in the refrigerating cycle is provided. By this, noise and vibration generated by a refrigerator itself such as noise generated by a flowing or boiling refrigerant in the compressor and an evaporator can be effectively removed, noise and vibration generated by resonance between vibration by a refrigerator and a wall or a cabinet can be attenuated and the effect of heat release can be enhanced. It is preferable that an outer casing of the adiabatic box is also made of a damping plate or a damping material is stuck to important positions of the outer casing made of an iron plate after forming an iron plate. Noise generated by a flowing or boiling refrigerant in the evaporator can be absorbed in a sound absorbing material layer and can be effectively attenuated by also providing a sound absorbing material layer between a heat insulator in the adiabatic box and the inner casing and between a heat insulator in the door and the door panel.
    • 一种制冷装置,其特征在于,包括一个绝热箱,该绝热箱设有一个开口的门,一个与所述绝热箱接触的机舱,以及一个制冷循环,其中机舱用阻尼板覆盖,并用连接装置 并且进一步地,所述制冷单元包括用于冷却循环中的用于冷却压缩机中的润滑油的油冷却器。 由此,可以有效地消除由冰箱本身产生的噪声和振动,例如压缩机中的流动或沸腾的制冷剂产生的噪音和蒸发器,由冰箱和墙壁或柜子产生的振动之间的共振产生的噪声和振动可以 被减弱,并且可以增强放热的效果。 优选的是,绝热箱的外壳也由阻尼板制成,或者阻尼材料在形成铁板之后被粘附到由铁板制成的外壳的重要位置。 在蒸发器中由流动或沸腾的制冷剂产生的噪声可以吸收在吸声材料层中,并且可以通过在隔热箱中的绝热体和内壳之间以及绝热体之间提供吸声材料层来有效地衰减 在门和门板上。

    • 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。
