Abstract

An electric cleaner or an autonomous electric cleaner that prevents scattering of garbage and dust towards the back and both sides thereby enhancing cleaning rate (absorbing rate) is provided. In the autonomous electric cleaner 1 having an absorbing port 2b for absorbing garbage and dust arranged at the bottom surface of the main body 2 facing the floor or the cleaning surface, the back blade 11 and the side blades 12 that contact the floor and receive the garbage and dust without allowing them to pass are arranged at the back part and both the left and right sides, respectively, of the absorbing port 2b.

Claims

1. An autonomous electric cleaner that autonomously travels and cleans a cleaning surface, the cleaner comprising:

an absorbing port facing the cleaning surface to absorb garbage and dust; and

a rotating brush arranged at the absorbing port and rotated to sweep the garbage and dust into the absorbing port, wherein

a blade that contacts the cleaning surface and receives the garbage and dust is arranged in the vicinity of a back part of the absorbing port parallel to the absorbing port and the rotating brush across the entire width of the absorbing port perpendicular to a traveling direction, and blades are arranged in the vicinity of both sides of the absorbing port so that a distance with respect to each other increases towards a front part, and arranged slightly slighted from a perpendicular direction and spaced apart by a microscopic gap that allows air to pass through with respect to the blade arranged at the back part.

2. An electric cleaner that absorbs garbage and dust from an absorbing port facing a cleaning surface, wherein

the cleaner is provided with receiving wall bodies respectively positioned at a back part and both sides of the absorbing port so as to contact the cleaning surface and receive the garbage and dust.

3. The electric cleaner according to claim 2, wherein

the absorbing port is provided with a rotating cleaning body that rotates and sweeps the garbage and dust into the absorbing port.

4. The electric cleaner according to claim 2, wherein

the receiving wall body at the back part of the absorbing port is disposed in a direction perpendicular to a traveling direction and parallel to the absorbing port, and

the receiving wall bodies on both sides of the absorbing port is disposed in a slanted manner so that a distance with respect to each other increases towards a front part.

5. The electric cleaner according to claim 2, wherein

the receiving wall body at the back part of the absorbing port and the receiving wall bodies at both sides of the absorbing port are positioned distant from each other with a microscopic gap therebetween that allows air to pass through.
