I have.

In this floor cleaning device, the motor 7 is
When rotated at 500 to 2500 rpm, the cleaning pad 15 rotates and the fan 13 rotates.
Since the air in the case 9 is exhausted from the exhaust port 10, the inside of the case 9 has a negative pressure, and the inside of the dust pack storage chamber 16 has a negative pressure.
The dust is exhausted through the dust pack mounting part 17, the dust pack 18, the dust pack storage chamber 16, the flexible hose 20, and the case 9, and the inside of the negative pressure part becomes negative pressure. For this reason, atmospheric pressure acts on the upper surface of the motor 7, the upper surface of the case 9, and the like, and negative pressure acts on the inner surface of the safety case 11, the upper surface of the pad stand 14, the lower surface of the cleaning pad 15, and the like. As shown in FIG. 4, the rotary cleaning means descends against the spring 8, and the lower surface of the cleaning pad 15 contacts the floor surface 21. Therefore, in such a state, the worker holds the handle 2 by hand,
If the floor cleaning device is moved onto the floor 21 to which the resin wax mixed with the heat-reactive resin is applied in advance, dust on the floor 21 is trapped in the dust pack 18 and the cleaning pad 15 is moved to the floor 21. In contact with the pad base 1
4. Since the cleaning pad 15 is rotated at 1500 to 2500 rpm, the resin wax is softened by frictional heat generated by friction between the cleaning pad 15 and the floor surface 21,
The minute projections on the surface of the resin wax are removed by the cleaning pad 15, and the surface of the resin wax is restored to a mirror surface state.

[0004]

However, in such a floor cleaning apparatus, since the lower portion of the cleaning pad 15 cannot be reliably made to have a negative pressure, the negative pressure does not act on the lower surface of the cleaning pad 15. In this case, since the cleaning pad 15 does not contact the floor surface 21 in this case, frictional heat is not generated, and the surface of the resin wax cannot be restored to a mirror surface state. For this reason, since the cleaning pad 15 must be moved over the floor surface 21 many times, the floor surface cannot be efficiently cleaned.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to provide a floor cleaning apparatus capable of efficiently cleaning a floor surface.

[0006]

In order to achieve this object, according to the present invention, a cleaning pad is attached to a pad base which rotates in a negative pressure section, and the cleaning pad is brought into contact with the floor surface so as to contact the floor surface. In the floor cleaning device for cleaning, a first hole is provided in the pad base, a second hole is provided in the cleaning pad, and the first hole and the second hole are communicated.

Further, in a floor cleaning apparatus for attaching a cleaning pad to a pad base which rotates in a negative pressure portion and contacting the cleaning pad with a floor surface to clean the floor surface, the cleaning pad has air permeability. A hole is provided in the pad base.

5 is a partially cut-away plan view showing a part of the rotary cleaning means of the floor cleaning device shown in FIG. As shown in the figure, a non-breathable cleaning pad 32 is removably attached to the pad base 31,
A fiber layer 34 having a thickness of about 1 cm is provided on the surface of the base cloth 33 of the cleaning pad 32. The fiber layer 34 is formed by twisting 80% by weight of a cotton spun yarn and 20% by weight of a nylon filament. The tufting is provided on the base cloth 33. That is, the above-described yarn is planted in the base fabric 33 by the tough dead processing, and the fiber layer 34 is provided. In addition, the base cloth 33
Is provided with a backing material 35 made of felt. Further, a first hole 36 is provided on the pad base 31, a second hole 37 is provided on the cleaning pad 32, and a hole 3 is provided.

2 with the fiber layer 34 of the cleaning pad 32 in contact with the floor surface coated with the resin wax.
When 1 is rotated at 1500 to 2500 rpm, frictional heat is generated mainly from the nylon filaments of the fiber layer 34, and the cotton spun yarn of the fiber layer 34 can be prevented from escaping. Since the temperature of the applied resin wax can be raised to 40 to 80 ° C., the resin wax is sufficiently softened. For this reason, since minute projections on the surface of the resin wax can be sufficiently removed, the surface of the resin wax can be surely restored to a mirror state, so that the cleaning pad 32 is placed on the floor only once. Since it is sufficient to move, the floor can be efficiently cleaned. Further, since the hole 36 is provided in the pad base 31 and the hole 37 is provided in the cleaning pad 32, and the hole 36 and the hole 37 are communicated with each other, it is possible to reliably exhaust the air below the cleaning pad 32. Cleaning pad 32
Since the lower portion of the cleaning pad 32 can be reliably set at a negative pressure, the cleaning pad 32 can be reliably brought into contact with the floor surface. For this reason, since the frictional heat can be reliably generated, the surface of the resin wax can be surely restored to the mirror state, and the cleaning pad 32 needs to be moved only once on the floor surface, so that the efficiency is improved. The floor can be cleaned well.

In the above-described embodiment, a non-breathable cleaning pad 32 is attached to the pad base 31, a first hole 36 is provided in the pad base 31, and a second hole 37 is provided in the cleaning pad 32. Provided, the hole 36 and the hole 37 were communicated,
An air-permeable cleaning pad may be attached to the pad base, and holes may be provided only in the pad base.In this case as well, a negative pressure can be reliably applied to the lower portion of the cleaning pad. Can be brought into contact with the floor surface. Also,
In the above-described embodiment, the case where the floor is cleaned with the resin wax mixed with the heat-reactive resin in advance has been described. However, the present invention can be applied to other cases. Since the lower portion of the cleaning pad can be reliably made to have a negative pressure, the cleaning pad can be reliably brought into contact with the floor surface, so that the floor surface can be efficiently cleaned.

[0011]

In the floor cleaning apparatus according to the present invention, since the lower portion of the cleaning pad can be reliably made to have a negative pressure, the cleaning pad can be surely brought into contact with the floor surface, so that it can be efficiently operated.
