Filed: 2000-12-29
Abstract: PURPOSE: An exhaust air reflux type vacuum cleaner is provided to enhance an intake capability of the vacuum cleaner by forming a plurality of intake holes for absorbing a foreign matter and generating a negative pressure using a refluxed exhaust air. CONSTITUTION: The first and second intake holes(2,3) are provided at a side of a head(10) to absorb a foreign matter and air simultaneously, and an exhaust air hole is formed at the first intake hole(2). A drive portion(22) provides a blast force for absorbing the foreign matter through the first intake hole. A dust collecting portion(24) stores a dust or waste absorbed by operating of the drive portion. A body includes an exhaust air-collecting chamber(26), which collects air passing through the dust-collecting portion. A main intake passage is formed between the first intake hole and the dust-collecting portion to introduce the foreign matter and exterior air into the dust-collecting portion by operating the drive portion. An exhaust air reflux passage(40) is formed between one side of the exhaust air collecting chamber and the exhaust air hole to float the foreign matter by the air collected at the exhaust air collecting camber. An ejector(30) and an auxiliary intake passage(34) are placed between the main intake passage and the second intake hole to absorb the foreign matter and the exterior air through the second intake hole by a negative pressure and to guide into one side of the main intake passage. An exhaust passage for ejector is formed between the other side of the exhaust collecting chamber and the ejector to guide a part of air of the exhaust air-collecting chamber into the ejector.
