[Prior art]

 FIG. 4 is a side view schematically showing an example of a conventional electric polish cleaner. Reference numeral 1 denotes a cleaner outer shell formed by a motor case 2 and a brush cover 3 and having a brush drive device 4 incorporated therein. A rotary brush 6 in which a brush 5a is planted on the lower surface of the rotary plate 5 is attached to an output shaft (not shown) of the brush drive device 4 projecting toward the front side by a fitting hole (not shown), and can be horizontally rotated. I am trying.

A pin bracket 7 for attaching a handle is provided at a predetermined position of the brush cover 3 and is attached to the pin bracket 7 so as to be vertically rotatable and fixed at a plurality of predetermined inclination angles. A handle 8 having a handle at its tip is provided, and small wheels 9 projecting downward in parallel are provided on both sides of the pin bracket 7.

Then, an electric polishing cleaner is installed so that the tip of the rotary brush 6 contacts the floor surface, and the brush drive device 4 is operated to rotate the rotary brush 6, so that the tilt angle is adapted to the work. By grasping the handle of the fixed handle 8 and tilting the electric polishing cleaner appropriately back and forth and left and right by human power, and changing the contact pressure of the rotating brush 6 against the floor surface, the reaction of the rotating brush 6 on the side where the contact pressure is increased is reversed. Using the action of moving in the direction of rotation, the electric polishing cleaner is moved to polish the floor surface.

When transferring the electric polishing cleaner, the handle 8 is erected substantially vertically, the base is fixed to the pin bracket 7, the handle of the handle 8 is grasped, and the small wheel 9 is brought into contact with the floor surface. The electric polisher is pulled down and the small wheels 9 roll on the floor so that the wheels can be transferred.

However, with the above-described electric polish cleaner, the floor surface and the tread surface of the stairs can be polished, but the kicking surface of the staircase cannot be polished. For this reason, in the past, the work of polishing the top of the staircase was performed manually by a worker using a cleaning brush or the like, but such work is a heavy labor work in a cramped posture, and the work efficiency is further improved. Had the problem of being bad.

Therefore, the applicant of the present invention, as previously described in Japanese Patent Application No. 4-33786, is an electric polishing cleaning machine capable of simultaneously polishing the floor surface and the step surface and staircase surface of stairs. Proposed a machine.

That is, the electric polishing cleaner described in Japanese Patent Application No. 4-33786 mentioned above has a front side surface of an outer shell of a cleaner having a rotating brush in the lower part, which is rotationally driven in a horizontal direction by an internal brush drive. In this configuration, an arc-shaped polishing cleaner that is oriented in the vertical direction, which is substantially orthogonal to the rotating surface of the rotating brush, is provided.The rotating brush of the electric brush cleaner is activated and moved appropriately to polish the tread surface of the stairs. At this time, by pressing the polishing cleaner provided on the front side surface of the outer shell of the vacuum cleaner against the kick upper surface of the floor, the polishing cleaner polishes the kick upper surface, whereby You can polish the upper surface at the same time.

[0009]

[Problems to be solved by the device]

 However, in the electric polishing cleaner described in Japanese Patent Application No. 4-33786, it is possible to polish the tread surface and the kick surface of the stairs at the same time, and the work can be performed significantly more than before. Although it is easier to perform and the work efficiency can be improved, since the polishing tool provided on the front side surface of the outer shell of the vacuum cleaner is pressed against the kick upper surface of the stairs to polish the kick upper surface, it is possible to clean the surface. It is necessary to move the electric polishing cleaner while pressing the tool against the kick surface with a certain amount of force, which requires a lot of work and puts a heavy burden on the worker.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an electric polishing cleaner capable of easily polishing the tread surface and the kicking surface of the stairs at the same time without requiring a force. Is.

[0011]

[Means for Solving the Problems]

 The present invention comprises a rotating plate provided at the lower part of the outer shell of the cleaner and a brush planted on the lower surface of the rotating plate so as to be horizontally rotatable by a brush driving device incorporated in the outer shell of the cleaner. A cleaning brush for cleaning an electric machine characterized in that a kick-up cleaning brush having a brush extending in the radial direction on the outer peripheral surface of a cylindrical body is integrally attached to the outer periphery of the rotary plate of the floor cleaning brush. Is.

[0012]

[Action]

 When the brush drive device built into the outer shell of the vacuum cleaner is driven, the kick surface cleaning brush rotates in conjunction with the rotation of the floor cleaning brush. Therefore, when the stair tread of the stairs is properly moved to polish the tread of the stairs, if the rotating kick upper surface cleaning brush is lightly pressed against the kick upper surface, the kick upper surface cleaning brush polishes the kick upper surface.

At this time, since it is possible to polish the kicking upper surface only by bringing the rotating kicking surface cleaning brush into contact with the kicking upper surface, it is possible to perform the work easily without polishing the kicking upper surface. .

【Example】

 FIG. 1 shows an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes an outer shell of a vacuum cleaner in which a brush drive device 4 is housed in a motor case 2. The output shaft 11 of the brush driving device 4 protruding toward the floor cleaning brush 14 includes a rotating plate 12 which can be fixed by fitting to the output shaft 11 and a brush 13 planted on the lower surface of the rotating plate 12. Is equipped for horizontal rotation.

A kick surface cleaning brush 15 is integrally attached to the outer periphery of the rotary plate 12 of the floor surface cleaning brush 14.

The kicking surface cleaning brush 15 includes a cylindrical body 16 and the cylindrical body 16 at positions equidistantly arranged on the outer peripheral surface of the cylindrical body 16 in the circumferential direction and equally spaced over the entire length in the height direction. The brush 16 has a structure in which a plurality of brushes 17 extending in the radial direction of the body 16 are planted, and in the illustrated case, the lower surface of the rotary plate 12 of the floor cleaning brush 14 and the lower end of the cylindrical body 16 are located at the same height. Installed. Further, the brush 17 on the lower end side of the cylindrical body 16 is planted toward the diagonally lower side of the cylindrical body 16 in the radial direction, and extends to the substantially same height position as the tip of the brush 13. Further, since the kicking surface 22 of the stairs has an inclination angle which rises from the tread surface 21 at an angle smaller than a right angle and is inclined toward the front side, the kicking surface 22 should be matched to the inclination angle of the kicking surface 22. The upper brush 17 of the upper surface cleaning brush 15 is short and the lower brush is long.

Further, a ring member 20 having strength is integrally attached to the lower portion of the outer shell 10 of the vacuum cleaner, and the side surface of the ring member 20 has a substantially U shape so as to straddle the cylindrical body 16. The arm 18 is fixed by a bolt 19, and the small wheel 9 is attached to the end of the arm 18. Further, a power supply connection box 23 fixed to the cleaner outer shell 10 is fixed to the horizontal portion of the arm 18 to further enhance the strength of the arm 18, and the power supply connection box 23 has A pin bracket 7 for attaching the handle is provided, and the pin bracket 7 has a base part attached so that it can rotate in the vertical direction and can be fixed at a plurality of predetermined inclination angles, and a handle having a handle at its tip part. 8 are provided. In the figure, reference numeral 24 is a handle provided on the upper surface of the cleaner outer shell 1.

FIG. 2 exemplifies a method of implanting the brush 17 in the cylindrical body 16. The brush 17 is substantially spiral-shaped in the cylindrical body 16 (a state in which the brush 17 is inclined with respect to the rotation axis of the cylindrical body 16). ) Has been planted in. Since the brush 13 is planted in a substantially spiral shape, when polishing the kick upper surface 22, for example, when the kick upper surface cleaning brush 15 is rotated in the A direction, dust and water are guided downward. There is.

Then, an electric polishing cleaner was installed so that the tip of the floor cleaning brush 14 abuts on the step surface 21 of the stairs, and the brush drive device 4 was operated to fix it at an inclination angle suitable for the work. By grasping the handle of the handle 8 and manually tilting the electric polishing cleaner forward, backward, leftward and rightward by manpower, and changing the contact pressure of the floor cleaning brush 14 with respect to the step surface 21 of the stairs, the floor on the side where the contact pressure increases The tread surface 21 is polished while moving the electric polishing cleaner by utilizing the action of the surface cleaning brush 14 which tends to move in the counter rotation direction.

At this time, since the kicking surface cleaning brush 15 is integrally attached to the floor surface cleaning brush 14, the kicking surface cleaning brush 15 rotates together with the floor surface cleaning brush 14 to move the electric polishing cleaner. When brushing the tread surface 21 of the stairs with the floor cleaning brush 14, the kick upper surface cleaning brush 15 is lightly pressed against the kick upper surface 22, so that the brush 17 radially implanted in the cylindrical body 16 is kicked. The upper surface 22 is evenly polished.

Further, since the brush 17 on the lower end side of the kick surface cleaning brush 15 extends to the same height position as the tip of the brush 13 of the floor surface cleaning brush 14, the step surface 21 and the kick surface 22 of the stairs are separated from each other. The corners can also be polished similarly to the tread surface 21 and the kicking surface 22 by the bending of the brushes 13 and 17.

Therefore, the tread surface 21 and the kicking surface 22 of the stairs can be polished at the same time, and further, the kicking surface 22 can be polished by simply pressing the kicking surface cleaning brush 15 against the kicking surface 22 of the stairs. As a result, work becomes easier and work efficiency improves.

Further, since the ring member 20 having strength is arranged below the outer shell 1 of the vacuum cleaner and the arm 18 is attached to the ring member 20, vibration of the brush drive device is prevented. , You can use the electric polisher in a stable condition.

FIG. 3 shows another example of a method of implanting the brush 17 in the cylindrical body 16. The brush 17 is arranged in the vertical direction so that the brush 17 is uniformly implanted in the side surface of the cylindrical body 16. It is arranged in a zigzag pattern.

The present invention is not limited to the above-described embodiments, but the method of planting the brush can be changed arbitrarily, and various other methods are possible without departing from the scope of the present invention. Of course, changes can be made.
