【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view schematically showing an example of an electric polishing cleaner of the first invention, and FIG. 2 is a view taken along the line II-II of FIG. In the figure, the same parts as those in FIG.

In the electric polishing cleaner of the present invention, a plurality of arms which are arranged at a predetermined interval in the circumferential direction of the front surface of the cleaner outer shell 1 and which horizontally protrude in the radial direction of the cleaner outer shell 1. 10 (3 in the peripheral direction in the figure, two steps vertically) are fixed, and the cleaning tool 11 is attached to the tip of the arm 10 so that the lower end is at substantially the same level as the tip of the rotary brush 6. It is installed.

The polishing / cleaning tool 11 has a base plate 11 a having a predetermined width and length and an arc shape along the brush covers 3, and a hard fiber material attached to the base plate 11 a. It is formed of a spongy body 11b having flexibility. The polishing tool 11 may be fixed to the arm 10 or the brush cover 3, and can be attached to and detached from the arm 10 by a bolt 26 or the like via a detachable bracket 25 as shown in FIG. The arm 10 may be attached to and detached from the vacuum cleaner outer shell 1. In addition, 12 is a tread of the stairs, and 13 is a kicking surface of the stairs.

When the rotary brush 6 of the electric polishing cleaner is operated and moved to polish the tread 12 of the stairs appropriately, the polishing cleaner 11 provided on the front side surface of the cleaner outer shell 1 is used to kick the stairs. The upper surface 13 is pressed against the upper surface 13 and the sponge-like body 11b of the polishing and cleaning tool 11 wipes the kick upper surface 13 to polish it. At this time, even if the kicking surface 13 is not a vertical surface but slightly tilted in the front-back direction with respect to the tread surface 12, the cancellous body 11b bends and absorbs the inclination angle, so that the surface of the cancellous body 11b is absorbed. The entire surface contacts the kick surface 13.

According to the above, since the polishing cleaner 11 is attached to the front side surface of the cleaner outer shell 1 of the electric polishing cleaner, it is possible to polish the step surface 12 and the kick surface 13 at the same time. . At this time, even if there is a slight gap between the outer periphery of the rotating brush 6 and the polishing tool 11, the rotating brush 6 has its bristle tips bent outward in the radial direction by the rotation, so that the entire tread 12 is covered. You can polish. The polishing / cleaning tool 11 may be provided with a brush-like member instead of the spongy body 11b.

FIG. 3 to FIG. 5 are plan views showing the outline of another embodiment of the polishing cleaner related to the electric polishing cleaner of the first invention.

The polishing / cleaning tool 14 shown in FIG. 3 comprises a base plate 14a and a sponge-like body 14b, which are substantially similar to the polishing / cleaning tool 11 of the embodiment shown in FIG. 2, and has a large circular arc when viewed from above. The base plate 14a is supported by an arm 15 having a predetermined length at the center and both end corners. In this case, each arm 15 is fixed to the detachable bracket 27, and the attachable / detachable bracket 27 is attached to the vacuum cleaner outer shell 1 by the bolts 26 or the like, so that the polishing cleaner 14 can be attached / detached together with the attach / detach bracket 27. I am doing so.

According to the polishing cleaner 14, since the base plate 14a is formed in a fan shape, the corners of the polishing cleaner 14 can be easily brought close to the ends of the kicking surface 13 of the stairs near the side wall surface. Since it is obtained, it is possible to polish every corner of the staircase upper surface 13. Further, when only the floor surface is polished by the electric polishing cleaner, the polishing cleaner 14 can be detached and the work can be carried out in a light state. In this case as well, a brush-like member may be provided instead of the spongy member 14b.

The polishing cleaning tool 16 shown in FIG. 4 has a brush-like shape that extends outward at the tip of the arm 15 that is provided in a plurality in the circumferential direction and that is arranged in two upper and lower steps in the same manner as in FIG. Is attached to the rotating brush 6 by means of a fixing tool 17, which is at the same level as the tip of the rotating brush 6 and extends vertically.

Since the brush-like brush 18 is used according to the polishing cleaner 16, the brushes 18 at both ends of the polishing cleaner 16 are deformed to the ends of the kicking surface 13 of the stairs near the side wall surface. Since they can be easily brought close to each other, it is possible to polish every corner of the kicking surface 13 of the stairs. Furthermore, even if the kicking surface 13 of the staircase has a slight inclination angle, the brush 18 having a large flexibility can absorb the inclination angle, so that the polishing tool 16 is evenly distributed over the entire surface of the kicking surface 13. Can be brought into contact. In this case, the brush 18 can be replaced by attaching and detaching the fixture 17.

The polishing tool 19 shown in FIG. 5 has a plurality of arms 15 provided in the same manner as in FIG. 4, and has a lower end portion extending substantially upward at the lower end portion thereof at substantially the same level as the tip portion of the rotary brush 6. A cylindrical brush 20 is arranged.

According to the polishing tool 19, since the brush 20 has a cylindrical shape, the direction of the electric cleaning machine facing the kicking surface 13 of the staircase is any direction within the range where the cleaning tool 19 is provided. Even in this case, it is the outer peripheral surface of the brush 20 that comes into contact with the top surface 13 of the stairs, and uniform polishing can be performed without changing the relative contact conditions.

A plurality of elastic bodies (for example, coil springs) 21 that protrude horizontally in the radial direction of the shell 1 and extend slightly outside the outer circumference of the brush cover 3 are provided in a predetermined height direction between the outer circumference of the brush cover 3 and the outer circumference of the motor case 2. It is fixed at the position, and the same cleaning tool 11 as shown in FIG. 1 is attached to the tip of the elastic body 21 so that the lower end is at substantially the same level as the tip of the rotating brush 6, and the cleaning is performed. For the positioning of the tool 11, a pin hinge 24 is provided to connect the central portion in the longitudinal direction of the lower part of the polishing tool 11 and the lower part of the brush cover 3 via the mounting plates 22 and 23. Other than the above, there is no difference from the one shown in FIG. 1, and the following description will be omitted.

When the rotary brush 6 of the electric polishing cleaner is operated and moved to polish the tread 12 of the stairs appropriately, the polishing cleaner 11 provided on the front side surface of the outer shell 1 of the cleaner is kicked on the stairs. The upper surface 13 is pressed against the upper surface 13 and the sponge-like body 11b of the polishing and cleaning tool 11 wipes the kick upper surface 13 to polish it. At this time, the spongy body 11b bends and the elastic body 21 bends even if the kicking surface 13 is not a vertical surface but is slightly tilted in the front-rear direction with respect to the tread surface 12, so that the inclination angle of the kicking surface 13 is absorbed. Therefore, the entire surface of the spongy body 11b of the polishing tool 11 can be brought into uniform contact with the kick surface 13.
