A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (17), an inlet fitting (21), an exhaust opening (18), and a dust filter (20) situated between the dust-collecting chamber (17) and the exhaust opening (18). To ac
A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (17), an inlet fitting (21), an exhaust opening (18), and a dust filter (20) situated between the dust-collecting chamber (17) and the exhaust opening (18). To achieve a compact design of the dust-collecting receptacle (14) that on the one hand, does not impair operation of the electric hand grinder or only does so to an insignificant degree and on the other hand, has a high dust-collecting efficiency, the inlet fitting (21), the dust-collecting chamber (17), the dust filter (20), and the exhaust opening (18) are situated one above another and preferably, the form of the dust-collecting receptacle (14) is adapted to the outer contour of the electric hand machine tool (FIG. 1).

What is claimed is: 1. A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (17), having an inlet fitting (21) that has a connecting opening (22) to be fitted onto a dust output fitting (13) of the machine and a mou
What is claimed is: 1. A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (17), having an inlet fitting (21) that has a connecting opening (22) to be fitted onto a dust output fitting (13) of the machine and a mouth (23) oriented toward the dust-collecting chamber (17), having an exhaust opening (18), and having a dust filter (20) situated between the dust-collecting chamber (17) and the exhaust opening (18), wherein the inlet fitting (21) extends only inside the receptacle in a lower region of the receptacle and does not extend over a contour of the receptacle and extends below the dust collecting chamber (17) and below the dust filter (20) and exhaust opening (18), so that an upper region of the inlet fitting (21) forms a bottom portion of the dust-collecting chamber (17), and wherein the mouth (23) of the inlet fitting (21) is situated close to a rear delimiting wall (152) of the dust-collecting chamber (17), wherein said rear delimiting wall (152) is oriented to the axis of the inlet fitting (21) with an angle of less than 90° to form a slope to guide an incoming airstream upwards into the dust collecting chamber (17). 2. The receptacle as recited in claim 1, wherein the dust-collecting chamber (17) extends beyond the connecting fitting (23) of the inlet fitting (21). 3. The receptacle as recited in one of claim 1, wherein the dust-collecting chamber (17) is enclosed by a box-shaped housing (15) that is open at the top and a cover (16) that closes the housing (15), the inlet fining (21) is integrated into the housing bottom (153), and the exhaust opening (18) is situated in the cover (16). 4. The receptacle as recited in claim 3, wherein the exhaust opening (18) extends over the entire cover (16) and is covered by a louvered grating (19). 5. The receptacle as recited in claim 3, wherein the dust filter (20) is attached to the underside of the cover (16), preferably by means of ultrasonic welding. 6. The receptacle as recited in claim 3, wherein the cover (16) has an elastic edge extending around the outside, which rests against the housing (15) and has an air-sealing function. 7. The receptacle as recited in claim 3, wherein the housing (15) is provided with locking hooks (24) that engage in corresponding locking recesses provided on the machine. 8. The receptacle as recited in claim 3, wherein the housing (15) with the cover (16) is adapted to the outer contours of the machine. 9. The receptacle as recited in claim 7, wherein the end wall (151) of the housing (15) bounded by the locking hooks (24) is designed to rest against the machine in a form-locked manner. 10. The receptacle as recited in claim 1, wherein the dust filter (20) and exhaust opening (18) are situated one above the other on top of the dust-collecting chamber (17).
