JP2001037696A - Method and device for cleaning carpet - Google Patents

Abstract

PROBLEM TO BE SOLVED: To remove easily pet animal hairs by rolling up and remove dust entangled in the pile of a carpet or the like by rubbing the flat side of a sponge whose friction coefficient with regard to a cleaned object is within a specified value. SOLUTION: A cleaning device for a carpet or the like has a practically flat surface 1a at least in one side of a sponge 1. When moving the flat surface 1a of the sponge, rubbing the surface of a carpet 2, it captures, rolls up and snowballs dust such as pet animal hairs. A cleaning device for a carpet or the like has preferably a friction coefficient of 0.2 to 1.8 with regard to an object to be cleaned, because an expandable vinyl chloride or the like has a too low friction coefficient with regard to a carpet material, its rolling up action is too weak and a material whose friction coefficient is 2 or higher exhibits high resistance when used and cannot entanglingly capture pet hairs easily.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning method and a cleaning tool for removing dust attached to carpets, carpets, etc.
In particular, the present invention relates to a cleaning method and a cleaning tool for efficiently and cleanly removing pet hair from a pet dog bred as a pet on a carpet or the like.

[0002]

2. Description of the Related Art When breeding pets such as dogs and cats indoors, the pet's hair entangled with carpets and carpets may become a burrow, etc. Often sticks and gives discomfort. Therefore, it is required to always clean carpets and the like. However, the pet's hair entangled with the hair foot cannot be easily removed by the conventional vacuum cleaner. In particular, when the pet is a long-haired dog, the tendency is even more remarkable. For this reason, recently, cleaning is performed by attaching dust such as pet hair to the adhesive tape using a roller-type cleaning tool in which an adhesive tape is wound in a roll shape. However, even if the above-mentioned roller-type cleaning tool is used, the hair that has entered the hair feet of the carpet cannot be easily removed, and the waste that has adhered to the adhesive tape is also troublesome. There is a problem in that the service life of the tape is relatively short, and frequent replacement is required, so that the economy is low.

In order to solve such a problem, a utility model registration
No. 3022843 discloses that the broom tip is made of a material having a high coefficient of friction such as rubber and resin sponge, and that the broom tip rubs between the carpets, thereby enabling cleaning of hair and the like dropped between the carpets. Proposal, but also utility model registration No. 3036950
Japanese Patent Laid-Open Publication No. H11-163873 proposes a cleaning tool in which a plurality of grooves are formed on a bottom portion and scrapes dust with the grooves.

[0004]

However, according to the results that the present inventors have tried, it is not always possible to sufficiently remove pet hair from a carpet by the means proposed above. Further, in some cases, dust such as pet hair adheres to the cleaning tool itself, and must be removed again, which is a hygienic problem and lacks comfort.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional cleaning tool, and can easily remove pet hair that has fallen on a carpet or carpet and that has become entangled with or entered into the hair feet. The aim is to provide an economical, hygienic and comfortable means that can be almost completely removed by work.

[0006]

Means for Solving the Problems The inventor of the present invention has proposed that when pet hair falling on a carpet is rubbed on a carpet with a flat surface of a sponge having certain conditions, the hair of the pet or the like is rounded in a bundle. The inventor has discovered that the snowball-type is enlarged and can be easily removed, and pursued the conditions to complete the present invention.

More specifically, the method for cleaning carpets and the like according to the present invention has a specific friction coefficient of 0.
By rubbing the flat surface of the sponge of 2 to 1.8 against the object to be cleaned, dusts entangled with hairy feet such as a carpet are rolled up in a bundle and removed. At this time, it is preferable that the sponge has a characteristic of being charged to a polarity opposite to that of the object to be cleaned by friction with the object to be cleaned.

[0008] In addition, a cleaning tool such as a carpet for carrying out the above invention has a coefficient of friction with an object to be cleaned of 0.2 to 0.2.
It is made of a sponge of 1.8 and has a substantially flat surface on at least one surface. In this case,
It is preferable that the sponge of the cleaning tool has a property of being charged to a polarity opposite to that of the object to be cleaned by friction with the object to be cleaned.

Further, it is preferable that the cleaning tool according to the present invention has a sponge having the above characteristics attached to a support, and that the support has a main body and a grip.

[0010] In addition to the above, it is preferable that the cleaning tool of the present invention is provided with an escape portion on the front surface of the flat surface so that pet hair can efficiently enter the friction surface. .

In the present invention, a particularly preferred sponge material is a rubber-based sponge material, particularly JIS K6301.
Is a rubber sponge having a C hardness of about 10-20.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on embodiments. FIG. 1 shows a cleaning tool 1 used in the present invention.
An example using a block-shaped sponge 1 is shown as an example. This sponge basically needs to satisfy the following conditions. At least one surface has a substantially flat surface. The coefficient of friction with the object to be cleaned is 0.2 to 1.8.

First, the cleaning tool such as a carpet according to the present invention needs to have a substantially flat portion 1a on at least one surface of the sponge 1, as shown in FIG. As shown in FIG. 2, when the flat surface 1a of the sponge is moved while rubbing the surface of the carpet 2 as shown in FIG. 2, the sponge is rounded while entangled with dust such as pet hair, and grows large like a snowball. It is a necessary condition to make it. Grooves and large projections rather hinder the performance of the above function, which is inconvenient. The term “substantially flat surface” as used herein refers to a macroscopically flat surface having a width of approximately 100 mm and a length of 200 mm, and includes a sponge surface having specific irregularities.

Further, the cleaning tool such as a carpet according to the present invention preferably has a coefficient of friction with the object to be cleaned of 0.2 to 1.8, more preferably 0.7 to 1.5. For example, foamed polyvinyl chloride, foamed polypropylene, or foamed polyethylene has too low a coefficient of friction with the above-mentioned carpet material and has too little an effect of curling the pet hair, and is generally not suitable for the purpose of the present invention. On the other hand, a material having a friction coefficient of 2 or more has a large resistance when used, and cannot easily entangle pet hair. The present inventor measured the coefficient of friction for various types of materials, and as a result, it was found that the above-mentioned range was excellent in workability and suitable for rolling while pet hair was entangled.

The above-mentioned coefficient of friction refers to a so-called dynamic coefficient of friction (sliding coefficient of friction), which is also determined by the material of the carpet, its surface condition, the material of the foamed sponge, the hardness, the degree of foaming, and the like. It is preferable to select and use one having an appropriate coefficient of friction in relation to the object to be used.

When the smooth surface of the sponge-like substance having the above properties is slid on the carpet while appropriately pressing the carpet, as shown in FIG. 2, the hair of pets such as dogs and the like scattered on the carpet is bundled. And is ready to be easily removed. That is, the dog's hair 3a that has entered or entangled in the hair of the carpet is pulled out by friction, and is drawn between the carpet 2 and the sponge 1 via the escape portion 4 (3b), and the sponge surface The sponge moves while rotating on the sponge surface due to moderate irregularities, and becomes entangled with other hairs to form a bundle.
c, 3d) Finally, the sponge 1 is discharged from the rear end as a bundle having a diameter of several mm or more, sometimes 10 mm or more.

In this manner, pet hair can be easily removed from a carpet or the like by the cleaning tool according to the present invention. To further enhance the effect, the sponge is rubbed with the object to be cleaned. It is preferable that the cleaning target has a characteristic of being charged in a polarity opposite to that of the cleaning target. Carpets and the like are usually manufactured using fibers such as wool, polyester, acrylic, and nylon, but these are generally positively charged by friction with polyurethane, polyethylene, vinyl chloride, Teflon, natural rubber, etc. Having. Conversely, the material has the property of being negatively charged. In the present invention, hair of a pet or the like to be cleaned is positively charged together with wool, polyester, or the like as a cleaning target. Therefore, in the present invention, if a material having the property of charging the carpet with a polarity opposite to that of the object to be cleaned is used, pet hair can be lifted out of the carpet or the like by electrostatic action, and more reliably, and Can thoroughly remove pet hair.

That is, the electrification due to friction contributes to further promoting the “snowball-type rounding” of the present invention. As such a substance charged to the opposite polarity to the carpet, a wool or polyester (including a blend thereof) usually used as a carpet may be a rubber-based material such as foamed rubber, for example, JIS K63.
A rubber sponge having a C hardness of 10 to 20 specified in 01 has a large capacity for generating static electricity and is most suitable. These are negatively charged with respect to the carpet material. However, it is not always necessary to limit to negatively charged ones. In short, what is necessary is just to be charged to a polarity opposite to that of a carpet or the like when moved on a carpet while rubbing.

Means for carrying out the above invention include:
A sponge having the above characteristics may be cut into an appropriate size and used as it is. In this case, it is also possible to clean small places such as corners of a room, between furniture, sofas, car seats, and the like.

As shown in FIG. 3, the sponge 1 is attached to a support portion 5 composed of a main body 5a and a grip 5b, and a relief portion 4 is provided by slightly shaving the front portion of the bottom surface of the main body 5a. This is advantageous because the carpet can be easily cleaned. Further, as shown in FIG. 4, if the support portion is formed in a relatively large flat plate shape and a long handle is attached as the grip portion 5b, a wide carpet surface can be cleaned in a comfortable posture. In addition, as long as the carpet surface is rubbed with a sponge having the above-described characteristics and the dust such as pet hair is rounded off, other modified examples can be taken.

[0021]

EXAMPLE A long-haired dog was bred for three days in a room lined with polyester carpet. Thereafter, the rubber sponge was adjusted to a width of 120 mm and a length of 240 mm, and the sponge was repeatedly rubbed on a carpet with one end thereof slightly raised as shown in FIG. 2 to collect dog hair. As a result, it was observed that the dog's hair scattered on the carpet or entangled with the bristle feet was discharged from the rear end of the sponge as a bundle having a diameter of about 10 mm. In addition, close observation on the carpet revealed that substantially no dog hair was found, including in the hair feet, indicating complete cleaning.

A similar experiment was performed with a vacuum cleaner and an adhesive roller type cleaning tool. As a result, when using a vacuum cleaner, the dog's hair entangled with the carpet's hair or entering the hair cannot be removed, and a large amount of dog hair remains even when visually observed. Was recognized. In fact, dog hair collected by the vacuum cleaner weighed only 50% of the weight collected using the present invention.

In the case of using an adhesive roller-type cleaning tool, as in the case of electric cleaning, the hair of the dog that has entered the hair feet of the carpet cannot be removed. Many dog hairs were found inside the carpet. The weight of dog hair collected by the adhesive roller type cleaning tool was only 55% of the weight collected using the present invention.

[0024]

According to the present invention, the carpet surface is cleaned by rubbing it with a sponge having a specific range of characteristics as described above. Because it was curled up and collected, it was possible to clean carpets and other floors extremely efficiently and hygienically.
