Robot cleaner
First Claim
1. A robot cleaner capable of running around by itself on a prescribed path for removing dust or dirt out of floor, the robot cleaner being furnished with a base case whose upper portion is equipped with a driving part for running and a suction part for removing dust or dirt and one side is formed with a dust suction aperture to which a dust suction inlet is inserted for inhaling dust or dirt from floor into said suction part;
- and with a top case covering on top of said base case, whereinsaid base case is formed at lower portion thereof with an inside vertical wall protruding so as to surround said dust suction aperture, and with an outside vertical wall external to said inside vertical wall so that a hollow part may be formed in-between surrounding said inside vertical wall; and
an auxiliary suction wall is installed between said inside vertical wall and outside vertical wall in such a manner that said auxiliary suction wall is movable by force of spring external to said inside vertical wall between a No. 1 position locating toward floor and a No. 2 position locating withdrawn from said No. 1 position opposite to floor, said auxiliary suction wall being positioned toward floor when no external forces are applied,wherein said auxiliary suction wall is formed along periphery thereof with a plurality of catching prominences that are supportable by insertion at the base case, and at both sides thereof with guide rods protruding, wherein said guide rod each is inserted by said spring capable of applying force in such a direction that said auxiliary suction wall should get far from said base case.

Abstract
A robot cleaner is mainly comprised of a base case whose upper portion is equipped with a driving part for running and a suction part for removing dust or dirt; and a top case covering on top of said base case, wherein said base case is formed at lower portion thereof with an inside vertical wall protruding so as to surround dust suction aperture, and with an outside vertical wall external to said inside vertical wall so that a hollow part may be formed in-between surrounding said inside vertical wall; and an auxiliary suction wall is installed between said inside vertical wall and outside vertical wall in such a manner that said auxiliary suction wall is movable by force of spring external to said inside vertical wall between a No. 1 position locating toward floor (F) and a No. 2 position locating withdrawn from said No. 1 position opposite to floor (F), said auxiliary suction wall being positioned toward floor (F) when no external forces are applied. According to this configuration, it is easy and convenient to install the auxiliary suction wall around dust suction inlet for enhancing easiness in dust suction.
