Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor disinfection method for disinfecting a floor of a hospital or the like.
[0002]
[Prior art]
In the conventional floor disinfection method, a liquid disinfectant is applied to the floor surface.
[0003]
[Problems to be solved by the invention]
However, in such a floor disinfection method, the floor must be dried after the liquid disinfectant is applied to the floor, so that the floor cannot be disinfected efficiently.
[0004]
The present invention has been made to solve the above-described problem, and has as its object to provide a floor sterilization method that can efficiently sterilize a floor surface.
[0005]
[Means for Solving the Problems]
To achieve this object, in the present invention, the heating pad is brought into contact with the floor surface and moves while rotating, and the frictional heat generated by the friction between the heating pad and the floor surface causes the heating pad to move. The temperature of the floor is 100 ° C. or higher.
[0006]
In this case, a fiber pad formed by tufting a yarn composed of 70 to 90% by weight of cotton fibers and 10 to 30% by weight of nylon fibers may be used as the heating pad.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic sectional view showing a heating pad rotating device used in the floor sterilization method according to the present invention. As shown in the figure, a handle 2 is attached to a main body 1, wheels 3 are provided on the main body 1, a support plate 4 is fixed to the main body 1, a motor 5 is attached to the support plate 4, and an output shaft of the motor 5 A pad base 6 is attached, and a pad 7 for temperature rise is detachably attached to the pad base 6.
[0008]
FIG. 2 is a front view showing a heating pad used in the floor sterilization method according to the present invention, and FIG. 3 is a partially cutaway bottom view showing the heating pad shown in FIG. As shown in the figure, a fiber layer 12 having a thickness of about 1 cm is provided on the surface of a base cloth 11, and the fiber layer 12 is formed by twisting 80% by weight of a cotton spun yarn and 20% by weight of a nylon filament. Is provided on the base cloth 11 by tufting. That is, the fiber layer 12 is provided by planting the above-described yarn in the base cloth 11 by tough dead processing. A backing material 13 made of felt is provided on the back surface of the base cloth 11. The whole is cut into a circular shape having a diameter of 19 inches (48.26 cm), a circular hole 14 is provided in the center, and the base cloth 11, the fiber layer 12, and the backing material 13 are used to increase the temperature of the heating pad 7. Is configured.
[0009]
Next, the floor sterilization method according to the present invention will be described. First, the heating pad 7 is attached to the pad base 6, and the motor 5 is rotated at 1500 to 2500 rpm, so that the heating pad 7 is rotated while being in contact with the floor surface 8 coated with the resin wax. In this state, when the operator moves the main body 1 and the heating pad 7 while holding the handle 2, the frictional heat generated by the friction between the heating pad 7 and the floor 8 causes the floor 8 to be heated. Increase the temperature to 100 ° C or higher. In this case, the floor 8 is sterilized by the heat.
[0010]
In such a floor sterilization method, the operator holds the handle 2 and puts the main body 1 and the heating pad 7 on the floor 8 while the heating pad 7 is rotated by rotating the motor 5. By moving, the floor 8 can be sterilized by heat, so that the floor 8 can be efficiently sterilized. In addition, since the fiber layer 12 is provided by tufting a yarn formed by twisting 80% by weight of a cotton spun yarn and 20% by weight of a nylon filament to the base cloth 11, the temperature of the floor 8 can be reduced to a maximum of about 170. Since the temperature can be as high as ° C., the floor surface 8 can be surely sterilized.
[0011]
In the above-described embodiment, a yarn in which 80% by weight of cotton spun yarn and 20% by weight of nylon filament are twisted is used, but 70 to 90% by weight of cotton fiber and 10 to 30% by weight of cotton fiber are used. It is preferable to use a yarn consisting of nylon fibers, more preferably a yarn consisting of 75 to 85% by weight of cotton fibers and 15 to 25% by weight of nylon fibers, and more preferably to a yarn of 78 to 82% by weight of cotton fibers. It is more preferred to use a yarn consisting of ２２22% by weight of nylon fibers. Further, in the above-described embodiment, a heating pad having a fiber layer 12 provided by tufting a yarn formed by twisting 80% by weight of a cotton spun yarn and 20% by weight of a nylon filament to a base cloth 11 is provided. Although 7 was used, a heating pad having a fiber layer composed of only cotton fibers may be used, and in this case, the temperature of the floor surface can be set to a maximum of about 120 ° C. Further, the temperature of the floor is preferably 120 ° C. or higher, more preferably 140 ° C. or higher, and even more preferably 160 ° C. or higher. In the above-described embodiment, the circular heating pad 7 having a diameter of 19 inches is used. However, the circular heating pad 7 having a diameter of 15 inches (38.1 cm) is used. ) May be used.

【The invention's effect】
In the floor sterilization method according to the present invention, the floor surface can be sterilized by heat by moving the temperature raising pad while rotating the temperature raising pad, so that the floor surface can be efficiently sterilized. be able to.
[0013]
Further, when a pad made of tufting a yarn composed of 70 to 90% by weight of cotton fiber and 10 to 30% by weight of nylon fiber to form a fiber layer is used as the temperature raising pad, Can be heated to a high temperature, so that the floor surface can be reliably sterilized.
