FIG. 1 is a bottom view of a self-propelled floor cleaner having a dust sheet affixed thereto.FIG. 2 is a side view of the self-propelled floor cleaner having the dust sheet affixed thereto.FIG. 3 is a plan view of the self-propelled floor cleaner having the dust sheet affixed thereto. - 1 denotes a dust sheet with an
annular sheet 2 having multiple (in the drawings, seven)protrusions 3 provided outside. - The
annular sheet 2 has a size similar to that of a conventional sheet, and has an outer perimeter approximately equal to the outer perimeter of the bottom part of a self-propelled floor cleaner. Theprotrusions 3 each have an acutely pointed tip. - The
annular sheet 2 and theprotrusions 3 are integrated together, and both are bendable and produced from paper or fabric (woven fabric or unwoven fabric). - As with a conventional dust sheet, this
dust sheet 1 has a removable structure, such as a hook-and-loop fastener, on the rear surface as before, thereby being removable from thebottom surface 5 of a disk-shaped self-propelled floor cleaner 4 (refer toFIGS. 2 and 3 ). - As with a conventional self-propelled floor cleaner, the self-propelled
floor cleaner 4 has a disk shape, and has atraveling part 6 and obstacle detecting means (not shown) on abottom part 5. - The traveling
part 6 is composed of three wheels, that is, pairedrear wheels front wheel 6 b positioned at a center ahead of therear wheels rear wheels front wheel 6 b rotates by being pushed by therear wheels - The obstacle detecting means is composed of one or more sensors of a type, such as a sensor detecting rotation or halt of the
front wheel 6 b or an infrared ray sensor in the form of radiating infrared rays toward front downward and, when detecting rotation or halt of the wheel, detecting a wall surface a predetermined distance ahead, or detecting that no more floor surface is present, instructs thefront wheel 6 b to change a traveling direction and rotate the self-propelledfloor cleaner 4. - 7 denotes a rod-shaped member installed upright and spaced a predetermined distance apart from an outer circumferential part on an upper surface of the self-propelled
floor cleaner 4. In the drawing, eight such members are provided at regular intervals. - An upper end of this rod-
shaped member 7 has a height equal to or higher than an upper end of the self-propelledfloor cleaner 4, and this rod-shaped member 7 serves as space height detecting means. - With the
rear wheels floor cleaner 4 travels on the floor. Then, cleaning is performed with thedust sheet 1 affixed to abottom part 5 wiping the floor. Then, when the obstacle detecting means detects a wall surface a predetermined distance ahead or detects that no more floor surface is present (when thefront wheel 6 b does not rotate, or the sensor detects a wall surface a distance ahead, or detects that nor more floor surface is present), the control part instructs thefront wheel 6 b to rotate the self-propelledfloor cleaner 4 and change the traveling direction. - Also, at corners of the floor, the
protrusions 3 wipe every corners appropriately bending, which were unable to be wiped so far. (refer toFIG. 4 ). - Furthermore, when the self-propelled
floor cleaner 4 enters a space under a chair and the rod-shapedmember 7 collides with an obstacle to cause thefront wheel 6 b not to rotate or when asensor 8 mounted on the rod-shapedmember 7 senses as such, the control part instructs thefront wheel 6 b to rotate the self-propelledfloor cleaner 4 and change the traveling direction. - Next, another reference example is described.
- In this reference example, while the shape of the
dust sheet 1 is identical to that of the above reference example, the shape of the self-propelledfloor cleaner 4 is different. - As depicted in
FIG. 5 , the self-propelledfloor cleaner 4 has a shape in which a disk-shaped lowermain body part 9 has fixed thereon a columnar-shaped uppermain body part 10 with its outer diameter a size smaller than that of the lowermain body part 9, and the height of the lowermain body part 9 and the uppermain body part 10 together is equal to that of the above embodiment (approximately 5 cm). This uppermain body part 10 serves as space height detecting means. - And, as with the above reference example, a traveling
part 6 that can freely change the traveling direction and obstacle detecting means (not shown) are provided on thebottom part 5 of the lowermain body part 9. - With the
rear wheels floor cleaner 4 travels on the floor. Then, cleaning is performed with thedust sheet 1 affixed to abottom part 5 wiping the floor. Then, when the obstacle detecting means detects a wall surface a predetermined distance ahead or detects that no more floor surface is present (when thefront wheel 6 b does not rotate, or the sensor detects a wall surface a distance ahead, or detects that nor more floor surface is present), the control part instructs thefront wheel 6 b to rotate the self-propelledfloor cleaner 4 and change the traveling direction. - Also, when the self-propelled
floor cleaner 4 enters a space under a chair and the uppermain body part 10 collides with an obstacle to cause thefront wheel 6 b not to rotate or when asensor 8 mounted on the uppermain body part 10 senses as such, the control part instructs thefront wheel 6 b to rotate the self-propelledfloor cleaner 4 and change the traveling direction. - Next, still another reference example is described.
- Also in this reference example, while the shape of the
dust sheet 1 is identical to that of each of the above reference examples, the shape of a self-propelled floor cleaner is different. - As depicted in
FIG. 6 , a self-propelled floor cleaner 11 includes amain body part 12 having a cylindrical member mounted in an inner perimeter part of an annular member and a spherical-shape traveling part 13 accommodated inside the cylindrical member. When themain body part 12 hits an obstacle, the travelingpart 13 touches any of a plurality of vertical slots to rotate the self-propelledfloor cleaner 4, and the travelingpart 13 changes the traveling direction. - Also in this reference example, as with each of the above reference examples, a rod-shaped
member 7 may be provided to an outer perimeter part of an upper surface of the annular member. - While the
dust sheet 1 has sevenprotrusions 3 extending outside theannular sheet 2 in each of the above reference examples, the number of protrusions may be one or more. However, if the number is too small, occasions to touch the corners of the floor decrease, contrary to the object of wiping every corner. Therefore, three or more may be preferably provided. - Also, while the
protrusion 3 is assumed to have a tip acutely pointed, without limitation, the tip may be rounded as depicted inFIG. 7 . However, unless the tip is acutely shaped (at an acute angle or with the acutely-shaped tip rounded), theprotrusion 3 may possibly extend off each corner at 90°, being unable to wipe well. - Furthermore, the
dust sheet 1 at least protrudes from the circular bottom part of the self-propelled floor cleaner, and may be in a triangular shape as depicted inFIG. 8 . - Still further, as depicted in
FIG. 9 , the annular part may be in a shape larger than the outer perimeter of the bottom part of the self-propelledfloor cleaner 4 to entirely extend off the bottom part. This means that the protrusion of the present invention includes the one having such a shape as described above. In this case, however, the protrusion needs to be made of a flexible thin material so as to be bendable to touch easily the corners of the floor. - Still further, as depicted in
FIG. 10 , the annular part may be in a shape larger than the outer perimeter of the bottom part of the self-propelledfloor cleaner 4 to entirely extend off the bottom part and may havemany incisions 19 in a direction from the center of the dust sheet toward the outer perimeter. The dust sheet smoothly bends when touching a corner of the floor, thereby every corner can be cleaned. - Still further, when the
protrusion 3 has each tip bent as depicted inFIG. 11 and affixed to the self-propelledfloor cleaner 4 with an adhesive (in the embodiment), a hook-and-loop fastener, or the like, the tip becomes less prone to bend, thereby eliminating the possibility of being unable to wipe the corners. - Still further, the rod-shaped member(s) 7 and the upper
main body part 10 need not be provided with thesensor 8. This is because an equivalent control can be performed even without thesensor 8 as long as it is detected that thefront wheel 6 b does not rotate. - Note that the
protrusion 3 may preferably protrude more than eachcorner 18 of a rectangle circumscribed around the circular bottom part of the self-propelledfloor cleaner 4. This is because, if it is shorter as depicted inFIG. 12 , theprotrusion 3 cannot touch each corner of the floor even when the self-propelled floor cleaner collides with a wall surface. -
