    Abstract: A centrifugal fan includes: an impeller configured to suction or discharge air; a motor configured to rotate the impeller; a housing configured to accommodate the impeller and have a suction port through which air is suctioned by rotation of the impeller and a discharge port through which air is discharged by rotation of the impeller; and a cut-off portion formed on one side of the discharge port. A flow cross-sectional area of air flowing in the housing is gradually increased from the cut-off portion to the discharge port in an air flow direction, and a distance from a lower portion of the impeller to an inner peripheral surface of the housing in a rotational axis direction of the impeller is gradually increased in at least a portion from the cut-off portion to the discharge port in the air flow direction.

    Abstract: A linear compressor is provided that may include a shell provided with a refrigerant inlet; a cylinder provided inside of the shell to form a compression space; a piston that reciprocates inside of the cylinder to compress a refrigerant in the compression space; and a motor assembly that provides a drive force to the piston and provided with a permanent magnet. The piston may include a piston body having a cylindrical outer circumferential surface and a surface-treated area, which may be processed with a material having a predetermined hardness value, and a valve support provided at an end of the piston body and having a suctioning hole be in communication with the compression space. The valve support may form a first non-surface-treated area, which is not surface-treated.

    Abstract translation: 提供一种线性压缩机，其可以包括设置有制冷剂入口的壳体; 设置在壳体内部以形成压缩空间的圆筒; 活塞，其在所述气缸内往复运动，以压缩所述压缩空间中的制冷剂; 以及向活塞提供驱动力并设置有永磁体的电动机组件。 活塞可以包括具有圆柱形外圆周表面和可以用具有预定硬度值的材料加工的表面处理区域的活塞体，以及设置在活塞体端部并具有吸入孔 与压缩空间通信。 阀支撑件可以形成未被表面处理的第一非表面处理区域。
