AI Technical Summary

Technical Problem

Dust containers in vacuum cleaners have limited capacity and variable air flow during cleaning, which reduces the cleaning time and requires frequent emptying.

Method used

A dust container with a conveyor belt and pulley system featuring flaps that compress and distribute dust between compartments, maintaining constant airflow and extending cleaning time by sealing and unsealing compartments during operation.

Benefits of technology

The conveyor belt system increases dust storage capacity and maintains constant airflow, thereby extending the cleaning time without needing to empty the dust container.

Abstract

A dust container (10) of a vacuum cleaner comprising a first compartment (11) provided with an air intake (12) and a filter (13), a second compartment (14) provided with a dirt outlet (15), wherein the first compartment (11) and the second compartment (14) are separated by a partition wall (16) provided with openings, wherein the dust container (10) has a dust compression unit comprising a conveyor belt (17), a driving shaft (18) and a pulley (19), wherein the conveyor belt (17) has at least two flaps (20) for dust distribution. The present invention provides a dust container in which the dust storage capability was increased thanks to the dust compression unit. The present invention provides a vacuum cleaner in which the cleaning time without necessity of emptying the dust container was also increased and in which the air flow during the whole cleaning process is more constant.
