Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a suction cleaner, and more particularly, to a suction cleaner head having a brush. 2. Description of the Related Art As a suction cleaner, a brush is provided on a head, and the brush is rotated about an axis perpendicular to a cleaning surface such as a floor or a wall to remove dust adhering to the cleaning surface. A device in which the material is scraped off by suction and removed by suction means is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 10-117972. [0003] In a suction cleaner in which such a brush is rotated about an axis perpendicular to the cleaning surface, a brush having a long bristle can be used. Can also bring a brush,
Dust adhering to those parts can be reliably released. In such a vacuum cleaner, a shaft is rotatably disposed on a shaft of a casing body constituting a head, and a spiral rotary blade is provided around the shaft. In addition, a brush is installed at the tip of the shaft. The brush is rotated by using the suction force of the suction means of the cleaner body by driving the fan of the cleaner body to rotate. Therefore, in such a suction cleaner, since the brush is moved by moving the tip of the brush in a circular shape with respect to the cleaning surface, the power of scraping dust at the center of the brush is weak, and the position of the head is shifted on the floor. It is necessary to perform cleaning while cleaning, and there is a possibility that dust adhering particularly to corners formed between the floor and the wall cannot be sufficiently removed. Further, the power for rotating the brush depends on the suction force of the main body of the cleaner. Therefore, when the pressure loss for rotating the brush increases, the function of sucking dust is reduced. Not only that, if the rigidity of the hose connecting the head and the cleaner body is low, the hose may be crushed by the suction force of the cleaner body and a suction passage may not be secured. Accordingly, an object of the present invention is to provide a suction cleaner having a higher cleaning function. In the vacuum cleaner of the present invention, a pressure chamber, a turbine chamber and a dust suction chamber are defined in a cylindrical main body casing, and the main body casing extends over these chambers. A hollow shaft is rotatably arranged on the shaft core,

Can be scraped. In addition, since the brush is driven by the turbine, a large dust collecting force can always be obtained without affecting the dust suction force at all. Further, since the dust is blown off by the jet air from the nozzle at the front portion of the center of the brush, that is, the portion where the brush is weak, the cleaning function is further enhanced. Further, in the suction cleaner of the present invention, a fan is arranged on a shaft driven by the turbine, and the dust is independently sucked into the dust suction chamber, and the air in the dust suction chamber is supplied to the cleaner body by the fan. Discharge. Therefore, the pressure of the hose connecting the dust suction chamber and the suction means such as the apparatus body is
