Abstract

A walk-behind sweeper has at least one sweeping roller and an air-cooled drive motor having a drive shaft and driving in rotation the at least one sweeping roller. At least one fan wheel conveys cooling air to the drive motor wherein the at least one fan wheel is driven by the drive shaft. A dirt collecting chamber is provided into which swept-up material that is swept up by the at least one sweeping roller is conveyed. The at least one fan wheel has an intake side connected by a flow connection to a working area of the sweeper so that at least a portion of the cooling air stream for the drive motor is taken in from the working area of the sweeper.

Description

technical field [0001] The invention relates to a hand sweeper. Background technique [0002] A cleaning machine is known from DE 19531327 A1, which has a bristle roller and a disk brush. The disk brush is driven by a drive unit. In addition, the sweeper has an air suction unit with a motor, which draws air from the dust box. Due to the presence of two motors for the disc brushes and the suction device, the sweeper is relatively heavy and has a complex structure. Contents of the invention [0003] The object of the present invention is to provide a cleaning machine which has a simple construction and a low weight. [0004] This task is accomplished by a walk-behind sweeper which has at least one sweeping drum and has an air-cooled drive motor (Antriebs motor) for rotationally driving the sweeping drum, and wherein the drive motor There is a drive shaft, which drives at least one fan impeller for delivering cooling air to the driving engine, wherein the cleaning machine...
