Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool floating in a water storage tank of a flush toilet and used.
More specifically, the present invention relates to a float cleaning tool for a water storage tank of a flush toilet, in which the silicon impregnated in the cleaning tool is melted and mixed water containing silicon is discharged to remove dirt adhering to the toilet bowl.

2. Description of the Related Art In a conventional flush toilet bowl, dirt, urine stones, microbial stains and the like adhering to the toilet bowl are washed away by drainage from a water storage tank. In addition, it is widely practiced to put a solid cleaning agent, an aromatic cleaning agent, or the like in a water storage tank, and to flush water containing a cleaning component dissolved from the cleaning agent into a toilet bowl to clean the dirt attached to the toilet bowl.

Due to the structure of the flush toilet bowl, water is retained in the accumulated water portion at the bottom in order to contain the odor from the waste discharge pipe. Therefore, it is not easy to clean the bottom surface and peripheral wall of the accumulated water part, the waste discharge port and the spray port provided on the inner peripheral surface of the toilet bowl. Dirt sticks to the toilet bowl.

If the dirt is relatively light, it can be removed by rubbing it with a brush or the like using a neutral toilet detergent, but for stubborn dirt with water stains sticking to the toilet bowl, chlorine bleaching is performed. It has been practiced to decompose and remove stains such as yellowing and darkening with a bleaching agent using an alkaline detergent containing agents.

However, when a chlorine-based detergent is used, the work must be performed with great care so as not to be dangerous to the human body, which is not preferable for daily use. Moreover, when this chlorine-based detergent is used, there is a risk of losing the processing function when the processing is performed in the septic tank. In other words, since the treatment in the septic tank is based on the principle of treating waste with microorganisms, the microorganisms will be reduced or killed by detergents and chemicals, and there is a high risk that the original functions of the septic tank will hardly be fulfilled. There was a problem that I couldn't.

Under such circumstances, an antifouling toilet bowl in which a fluorine compound is chemically bonded to the surface of the toilet bowl has recently been proposed as a toilet bowl to which dirt is unlikely to adhere. This antifouling toilet is a fluorine-based compound chemically bonded to the surface of the toilet bowl so that silicon dioxide (silicic acid), which is the main component of dirt called scale, does not adhere to the toilet bowl. .

However, in order to chemically bond the fluorine-based compound to the surface of the toilet bowl to prevent stains, it is necessary to use a coating film having an extremely thin thickness, and it is difficult to increase the adhesion strength, which is a great deal of trouble. There was a problem that the toilet bowl was expensive as well as being expensive.

[0008]

By the way, a ceramic toilet bowl, which is a ceramic product, is glazed in order to prevent water leakage and to make the surface smooth and slippery so that dirt is not easily attached. It has been baked. And, in general, the main component of the glaze is silicic acid.

[0009] On the other hand, it has been recently known and announced that the main component of the scale that causes the stain on the toilet bowl is silicon dioxide (silicic acid) contained in water as described above. (July 13, 2001 Asahi Shimbun article) That is, since both the toilet bowl and the scale are formed of the same main component, the scale is chemically bonded to the surface of the toilet bowl, resulting in "integration". It becomes rough on the non-slip surface, and dust, iron, bacteria, etc. adhere to it and become scale. If the scale adheres to the toilet bowl, it will not be able to remove the roughness even if it is washed, and there is a problem that it becomes dirty again immediately.

The present invention has been researched and developed with the object of solving the above problems, and silicon is permeated into silicic acid which is the main component of scale and silicic acid which is glazed on the surface of the toilet bowl. It is therefore an object of the present invention to provide a float cleaning tool for a water tank of a flush toilet, which can remove scales and prevent scales from adhering for a certain period of time.

[0011]

As means for solving the above-mentioned problems and achieving the object, in the present invention, a hydrophobic and lipophilic fiber material impregnated with water-soluble silicon and a floating member are used as cores. Water storage tank for flush toilets, which is used as a material, the core material is covered with a hydrophobic and lipophilic coating material impregnated with water-soluble silicon, and a string for suspending the cleaning tool body is provided. A float cleaning tool was developed and adopted.

Further, according to the present invention, in the float cleaning device for a flush toilet tank configured as described above, a knitted cloth, a woven cloth, or a cutting waste cloth thereof in which the fiber material of the core material is a fiber having a specific gravity of 1 or less. , A non-woven fabric, a floating member is a plastic pipe having a specific gravity of 1 or less, and a fiber material is used in a large amount, and a floating member is used in a small amount. The floating material is a knitted fabric, woven fabric, cutting waste cloth or non-woven fabric thereof made of fibers having a specific gravity of 1 or more, and the floating member is a plastic pipe having a specific gravity of 1 or less. We have developed and adopted a float cleaning tool for water tanks of flush toilets that uses a large amount of water.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 4 show a float cleaning tool for a water tank of a flush toilet according to the present invention,
The cleaning tool body 1 includes a coating material 2 made of hydrophobic and lipophilic fiber threads impregnated with water-soluble silicon, and a core material 3 covered with the coating material 2, that is, impregnated with water-soluble silicon. Fiber material 3a consisting of hydrophobic and lipophilic fibers
And a floating member 3b of a plastic pipe and a string 4 for suspending the cleaning tool main body 1 in a water storage tank.

The above-mentioned coated cloth 2 is a bottomed tubular material knitted or woven with hydrophobic and lipophilic synthetic fiber threads such as polypropylene, polyvinyl chloride, polyester and acrylic, and is made of water-soluble silicone. Is impregnated with. Among the synthetic fiber yarns, the most preferable one is a polypropylene yarn yarn having a low specific gravity and knitted in a tubular shape.

Further, one fibrous material 3a constituting the core material 3 is a non-woven fabric or knitted fabric made of hydrophobic and lipophilic synthetic fibers such as polypropylene, polyvinyl chloride, polyester and acrylic, which are the same as the above-mentioned covering fabric 2. It is impregnated with water-soluble silicon by a cloth, a cloth, or a cloth for cutting them. In particular, when a cutting waste cloth is used, the loss of the cloth is eliminated, the generation of dust is reduced, and the cost is reduced.

In order to impregnate the coated fabric 2 and the fiber material 3a with silicon, the smoothing agent used in the processing step of the raw yarn and the pre-knitting step is washed with warm water at 50 ° C. using an oil removing agent. After processing, the water-soluble silicone agent is mixed in warm water at 50 ° C. to adhere and penetrate.

Another floating member 3 which constitutes the core material 3.
b preferably has a specific gravity of 1 or less and a length of about 4 to 8 mm. Among them, a polyethylene pipe having a specific gravity of 0.94 and a length of 6 mm is preferable from the viewpoint of lightness and bulkiness. .

The fibrous material 3a and the floating member 3b are mixed at an appropriate ratio, housed in the lower half portion 2a of the tubular knit which becomes the covering fabric 2, formed into a ball shape, and the upper end portion thereof is bound by a binding band. At the same time, the upper half portion 2b is turned over to cover the outer surface of the covering cloth of the lower half portion 2a to form a double coating, and the upper end opening thereof is pulled to be bound by the binding band 5.

The string 4 is made of nylon thread or a thin string for suspending the cleaning tool body 1. One end of the string 4 is attached to the binding band 5, and the locking piece 6 is fixed to the other end. This string 4
Has a length such that when the cleaning tool body 1 is placed in the water storage tank 7, it is restricted so that it can float only within a certain range.

An example of the use of the float cleaning tool of the present invention thus constructed will be described. As shown in FIG. 5, a locking piece 6 fixed to one end of the string 4 is hung outside the water storage tank 7. When the cleaning tool main body 1 is put into the water storage tank 7, the cleaning tool main body 1 is in a state of floating on the water surface in the water storage tank 7.
At this time, if the cleaning tool main body 1 freely floats, the movement of the ball tap 8 is hindered and the water does not stop. Therefore, the string 4 is attached so that it can float only within a certain range.

While being suspended, the cleaning tool body 1
The water-soluble silicon impregnated in the base material, that is, the silicon impregnated in the coating material 2 and the fiber material 3a is gradually eluted and the water in the water storage tank 7 becomes mixed water containing silicon. The mixed water is washed away and penetrates the scales and the silicic acid that has been glazed on the surface of the toilet by silicon, and the good mold releasability of the silicone makes it possible to remove stains such as scales attached to the toilet without using a detergent. It can be easily removed by rubbing with a brush, and the water repellent property of silicon can prevent redeposition of scales for a certain period of time.

In the cleaning tool main body 1, the water repellency decreases as the silicon gradually elutes, and the water floating on the water surface gradually enters the water to completely elute the silicon. Then, the whole becomes floating in water, and the impregnated silicon can be eluted over a long period from the beginning to the end.

Next, specific examples of the present invention will be described. Example 1 A tubular knitted covering fabric 2 having a length of 22 cm and a weight of 10 g was knitted by using polypropylene yarn impregnated with water-soluble silicon. One end of the coated cloth 2 is sewn to close the opening, and the fibrous material 3a made of polypropylene non-woven fabric of the core material 3 is placed in the lower half 2a thereof.
g, 8 g of a polyethylene pipe having a length of 6 mm is used as the floating member 3b, and the diameter of the lower half portion 2a of the covering fabric 2 is 8 cm.
It is formed into a ball shape and the upper part is bound with a binding band,
The upper half portion 2b of the covering cloth 2 is reversed to cover the outer surface of the covering cloth 2 of the lower half portion 2a to be double-coated, and the opening is bound with a binding band 5, and a plastic locking piece is attached to one end. The nylon thread 4 to which 6 was fixed was passed through the binding band 5 to obtain the cleaning tool body 1. The cleaning tool body 1 was placed in a water storage tank 7 having a capacity of 4 liters, and a water stain adhesion test was conducted on a toilet bowl. After 120 days, it adhered.

(Comparative Example 1) The floating member 3b of Example 1
A cleaning tool body 1 similar to that of Example 1 except that the polyethylene pipe was not used was put in the water storage tank 7 and a water stain adhesion test was performed on the toilet bowl. After 40 days, it adhered. As a result, it can be seen that when the floating member 3b is not provided, the floating member 3b floats in water from the beginning, and the impregnated water-soluble silicon is eluted in a short time.

(Example 2) A polyvinyl chloride yarn impregnated with water-soluble silicon was used to measure a length of 22 cm and a weight of 15
g of tubular knitted knitted covering fabric 1 was knitted. One end opening of this covering cloth 1 is sewn and closed, and the lower half 2
Into a, 30 g of a fiber member 3a made of cutting scraps of polyvinyl chloride knitted fabric of the core material 3 and 30 g of a polyethylene pipe having a length of 6 mm as a floating member 3b are put, and the lower half portion 2a of the coated fabric 2 is put. Is formed into a ball shape with a diameter of 10 cm, and the upper part thereof is bound with a binding band, and the upper half portion 2b of the covering cloth 2 is bound.
To cover the outer surface of the covering fabric 2 in the lower half portion 2a so as to be double-coated, and to tie the opening with a binding band 5 and to fix the nylon thread 4 having a plastic locking piece 6 fixed at one end. The cleaning tool body 1 was obtained by passing through the binding band 5. The cleaning tool body 1 was placed in a water storage tank 7 having a capacity of 4 liters, and a water stain adhesion test was conducted on a toilet bowl. After 120 days, it adhered.

(Comparative Example 2) Floating member 3b of Example 2
The cleaning tool main body 1 similar to that of Example 2 except that the polyethylene pipe was not used was put in the water storage tank 7, and the adhesion test of scale was performed on the toilet bowl, and it adhered after 15 days. As a result, when the floating member 3b is not provided, it floats in water from the beginning, and it can be seen that the impregnated water-soluble silicon is eluted in a short time.

Further, the cleaning tool main body 1 of Example 1 was placed in the water storage tank 7 and a dirt removal test was conducted using a toilet with dirty dirt. The stains were yellowed due to water stains on the bottom of the toilet bowl, the peripheral wall of the reservoir, and the outlet.

At the bottom of the accumulated water at the bottom of the toilet bowl, rubbing with a brush after the lapse of 3 days could completely remove the scale. Further, the accumulated water peripheral wall surface could be slightly removed by rubbing with a brush after 30 days, but it took about 150 days until it completely disappeared. Furthermore, regarding the scale on the outlet,
After 15 days, it started to scrape with a brush, and after about 60 days with a brush, the scale was completely removed.

Further, in order to examine the safety of water quality using the cleaning tool body of this article, 3 liters of groundwater was placed in the aquarium, and 10 black medaka fish on the 14th day after hatching were placed,
One of the articles of Example 1 is put in the observation, but 4
The survival of all 10 animals could be confirmed even after 0 day.
