Self-propelling cleaner
First Claim
Patent Images
1. A self-propelling cleaner comprising:
- a main body;
a cleaning unit that accommodates dust taken from a cleaning nozzle through a dust transporting pipe within a dust chamber;
a propelling unit that automatically moves and turnarounds the main body within a preset region;
a controller for controlling the propelling unit and the cleaning unit;
a microphone mounted in the dust transporting pipe;
a dust full detection unit that detects a full state of dust in the dust chamber based on a sound volume picked by the microphone and a preset reference sound volume;
a switching unit for switching cleaning modes; and
a display that indicates the full state when the dust full detection unit detects the full state, wherein the propelling unit stops moving the main body when the dust full detection unit detects the full state, wherein the propelling unit moves the main body in different manner from that at a time of normal cleaning when the dust full detection unit detects the full state, wherein the dust full detection unit switches the reference sound volume according to the cleaning mode switched by the switching unit.

Abstract
In a dust transporting pipe 6, a microphone 20 is installed in a predetermined position. An output signal of the microphone 20, that is, a voltage signal of amplitude according to sound volume of the inside of the dust transporting pipe 6 picked is inputted to a controller 10. Initial amplitude according to sound volume of the inside of the dust transporting pipe 6 in the case of sucking dust in a state in which there is no dust inside a dust chamber 5 at all and the amount of change in amplitude indicating what amount amplitude changes from the initial amplitude in the case that the dust chamber 5 becomes full of dust are previously stored in the controller 10.
