    • A suction head is provided for removing debris from a surface. The suction head includes a suction nozzle which has a generally semi-circular groove formed on an interior surface of the suction nozzle. Additionally, there is a suction hole formed at a generally central region of a rear surface of the nozzle and communicating with the semi-circular groove. Further, a uniform pressure forming region is provided at a longitudinally extending side of the semi-circular groove, and a suction pipe is mounted to the suction hole to guide air in the semi-circular groove through the suction hole.
    • 提供吸头以从表面去除碎屑。 吸头包括吸嘴,其具有形成在吸嘴的内表面上的大致半圆形的凹槽。 此外,在喷嘴的后表面的大致中央部形成有与该半圆形槽连通的吸入孔。 此外,在半圆形槽的纵向延伸侧设置均匀的压力形成区域,并且吸入管安装到吸入孔,以通过吸入孔引导半圆形槽中的空气。

    • Disclosed herein is a blowing apparatus for refrigerators. The blowing apparatus includes a centrifugal fan. The centrifugal fan comprises a hub plate connected to a shaft of the motor, a plurality of blades attached to the hub plate in the radial direction of the hub plate for forcing cool air to flow, and a ring-shaped shroud connected to ends of the blades. The ratio of the inner diameter of the centrifugal fan, formed through connection of the inner ends of the blades, to the outer diameter of the centrifugal fan, formed through connection of the outer ends of the blades, is 0.63±0.01. With the blowing apparatus for refrigerators according to the present invention, flow loss is minimized. Consequently, the present invention has the effect that energy consumption is reduced, noise is decreased, and thus the refrigerator is quietly operated.
    • 本文公开了一种用于冰箱的吹风装置。 吹风装置包括离心式风扇。 离心风扇包括连接到电动机的轴的轮毂板,沿着毂板的径向方向附接到轮毂板的多个叶片,用于迫使冷气流动;以及环形护罩,其连接到 刀片。 通过叶片的内端连接而形成的离心式风扇的内径与通过叶片的外端连接形成的离心式风扇的外径的比例为0.63±0.01。 根据本发明的用于冰箱的吹风装置,流量损失最小化。 因此,本发明具有能量消耗降低,噪音降低,冰箱静音运转的效果。

    • Disclosed are a mobile robot and a controlling method thereof. The mobile robot comprises: a case; and a sensor unit having two or more sending portions and two or more receiving portions arranged on an outer surface of the case separately and alternately. The plurality of sending portions and receiving portions are arranged in an alternating manner, thereby having a directivity. Also, since signals received through the receiving portions are judged based on a reference value, an area unallowable to be detected for an obstacle sensing is minimized, which allows an obstacle to be detected more accurately. When the obstacle corresponds to a side wall on the basis of a moving path of the mobile robot, a distance between the side wall and the mobile robot is calculated based on signals received by the receiving portion closest to the side wall. Accordingly, the mobile robot can move with maintaining a constant distance from the side wall.
    • 公开了一种移动机器人及其控制方法。 移动机器人包括:壳体; 以及传感器单元,其具有两个或更多个发送部分和两个或更多个接收部分,分别和交替地布置在壳体的外表面上。 多个发送部分和接收部分以交替的方式布置,从而具有方向性。 此外,由于基于参考值判断通过接收部分接收到的信号,所以不容易被检测用于障碍物感测的区域被最小化,这允许更准确地检测障碍物。 当障碍物基于移动机器人的移动路径对应于侧壁时,基于最靠近侧壁的接收部分接收的信号来计算侧壁和移动机器人之间的距离。 因此,移动机器人可以在与侧壁保持恒定距离的情况下移动。
