Autononmous cleaner

Abstract

An autonomous cleaner having: a cleaner body in which a cavity is defined; and a dust container removably fitted in the cavity, the dust container having an air and debris inlet, and an air outlet for admitting an air flow through the dust container. The dust container has a dust compartment for the debris, and the ratio between the dust compartment volume and the cleaner body volume is within the range 0.1 to 0.2.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an autonomous cleaner.BACKGROUND OF THE INVENTION[0002]In order to facilitate the work related to vacuum cleaning of floor areas in different types of building structures, autonomous vacuum cleaners have been available on the market for some time. These autonomous cleaners automatically move in different directions over the floor to clean the floor area without human involvement. The cleaner is either moving randomly or according to a predetermined pattern over the floor until a navigation system detects an obstacle or the cleaner hit some obstacle and turn. Consequently, the size and design of the cleaner is important factors to ensure that the cleaner is able to access as large area as possible of the floor since a cleaner with a limited height and width will be able to access areas under and around furniture, or in close corners more easily.[0003]Autonomous cleaners have a cleaner body which comprises the different comp...

AI Technical Summary

Benefits of technology

[0012]The cleaner according to the invention provides an efficient autonomous cleaner that is able to cover large floor areas without requiring emptying of the dust container since the volume of the dust container in relation to the volume within the cleaner body is larger than in known cleaners. The increased dust container volume is a result of extensive work to optimize the different components arranged in the cleaner body and the internal configuration and layout of the different components required to ensure that the autonomous cleaner work as intended.

[0023]In one embodiment of the autonomous cleaner, the cleaner body has a substantially triangular shape with a wider forward than aft end. The brush roll is arranged in the forward end and the dust container in the centre of the cleaner body. The triangular shape improves the possibilities for the cleaner to access areas that otherwise would have been difficult to reach.

Problems solved by technology

As can be seen in the figures a number of different components are fitted within the cleaner body which in combination with the desired small outer size of the cleaner makes the room for the different components limited.

The limited space within the cleaner body has some severe drawbacks on the disclosed cleaner.

The small volume results in that the container must be emptied more frequently to ensure the desired cleaning result which is devastating since the container must be emptied manually.

Furthermore the removal and fitting of the dust container in the cleaner body is complicated du to the complex design of the dust container and the surrounding structures in the cleaner body.
