  • Publication number: 20090100637
    Abstract: The present invention discloses a vacuum cleaner which can remove substances from the bottom by a rotary force of a brush and a vacuum pressure operated on a suction head by rotatably installing the brush on the suction head. The vacuum cleaner consults a user's convenience by preferentially sucking thin and long substances such as hairs or furs of a pet dog not to be wound around the brush. The vacuum cleaner includes a suction head being installed at a front end of a suction path for sucking substances by a vacuum pressure generated by a suction motor, and having a suction hole for sucking the substances on its bottom, a brush installed on the suction hole of the suction head, and rotated to contact the bottom, and a hair tunnel formed on the suction head not to interfere with the brush, for preferentially sucking thin and long substances from the bottom.

  • Patent number: 7510471
    Abstract: The present invention relates to a flow spreading mechanism, in particular a flow spreading mechanism used with refrigerators or air conditioners to enhance spreading of cool or warm air. To achieve the above-mentioned object, this invention comprises at least one inlet (200) through which fluid flow comes in; a flow separator means (110) dividing the flow coming through the at least one inlet (200) into at least two separate flows; and an outlet (300) through which at least two of the at least, two flows having been divided into separate flows by the flow separator means go out after they meet again, thereby forming complex vortices near the outlet, which make the flow going out of the outlet swing. Flow spreading mechanism of the present invention provides a better uniformity of temperature distribution for refrigerators or air conditioners, compared with the simple-ducted outlet of the prior art.
