Definitions
- the present invention relates to an automatic cleaning device, and, more particularly, to an automatic cleaning device having a dirt receptacle sensor unit to sense the presence of a dirt receptacle.
- an automatic cleaning device is a self-running vacuum cleaner.
- the automatic cleaning device automatically finds its way back to its charging station to recharge when needed. If the cleaning hasn' t been completed when the automatic cleaning device needs to be charged, the automatic cleaning device continues cleaning when charging is finished.
- FIG. 1 is a schematic longitudinal sectional view illustrating the general configuration of a conventional automatic cleaning device.
- the conventional automatic cleaning device comprises: a body 100; a fan motor 200 mounted in the body 100 to generate a suction force; and a dirt receptacle 300 containing a filter 301 therein.
- the dirt receptacle 300 is detachably mounted in an installation chamber 101 defined in the body 100.
- the installation chamber 101 is connected with the fan motor 200, and thus, the dirt receptacle 300 is connected with the fan motor 200.
- the conventional automatic cleaning device further comprises: a suction pipe 400; a suction head 500; and a brush 600.
- the suction pipe 400 is penetrated through the bottom of the dirt receptacle 300 to be connected with the filter 301.
- the suction head 500 is coupled to a lower end of the suction pipe 400 to suction dust and dirt from the floor.
- the brush 600 is located in the bottom of the suction head 500 so that it is exposed to the outside to come into contact with the floor.
- the body 100 is provided at the bottom thereof with a plurality of wheels exposed to the outside.
- the wheels include a drive wheel 700 for the self-running of the body 100 and a plurality of auxiliary wheels 701 to assist the operation of the drive wheel 700.
- a controller 102 is mounted in the body 100 to control the traveling direction of the automatic cleaning device.
- the automatic cleaning device travels in a predetermined direction in accordance with operation of the controller 102, so that it suctions dust and dirt from the floor via the suction head 500 into the suction pipe 400 during the driving of the fan motor 200. Subsequently, the suctioned dust and dirt are caught while passing through the filter 301.
- the conventional automatic cleaning device is adapted to clean a room while discharging filtered air.
- the above-described prior art has a problem in that it has no function of sensing the presence of the dirt receptacle.
