Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basin equipped with a basin and a water discharging device, which prevents the remaining water after spouting from being supplied to the basin continuously or intermittently and prevents the adhesion of scale. The present invention relates to a method for performing the method and a washroom that enables the method. Further, the present invention relates to a coating composition for preventing scale from adhering to a wash basin in a wash basin and making the wash basin hard to be stained.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for sanitary spaces to be clean, and it has been widely desired to keep the basin surface sanitarily clean. As a method of keeping the basin surface sanitary clean in general households since ancient times, surfactants,
A method has been adopted in which a detergent such as a weak acid or a weak alkaline agent is attached to a scourer or brush to strongly rub the ceramic surface, and both chemical removal with the detergent and physical removal by scrubbing with a scrub brush are used. .

[0003]

Heretofore, as one form of basin dirt, there is dirt due to water drops dripping from a spout of a water discharge device. This scale tends to adhere to a fixed area, and this scale can be sufficiently removed by a method of rubbing the surface of a ceramic with a detergent such as the above-described surfactant, weak acid, or weak alkali onto a scourer or a brush. Could not be removed. In view of the above, an object of the present invention is to provide a washroom facility in which the water stain is less likely to occur. It is another object of the present invention to provide a coating composition for a wash basin having a water discharging device that makes it difficult for the basin stain to occur. Still another object of the present invention is to provide a method for using the coating composition to make the above-mentioned scale less likely to occur on the surface of a washbasin.

[0004]

When observing the surface of a basin used for a long period of time, there is a portion where the residual water continues to be supplied intermittently below the spout and gloss of the surface of the pottery is lost. It was found that water scale formed of a thin film mainly composed of silica was formed. Furthermore, the surface to which the scale was attached had a large surface roughness, so that the stain was easily attached, and the surface state was such that microorganisms such as molds could easily propagate. From the above observations, it is estimated that the adhesion of scale is one of the stains on the surface of the pottery used for a long period of time, and the mechanism of the generation is as follows. (1) On the ceramic surface just below the spout, the remaining water after spouting from the spout continues intermittently dripping for a long time and stays in the vicinity. In almost the same position). (2) The retained water is dried at that location to form a film of scale (a film made of an inorganic substance such as SiO2 or CaO, which is a mineral component contained in the water, is formed. Rubbing does not completely remove it). Therefore, it is considered that the best way to prevent the generation of scale is to suppress or prevent the intermittent supply of residual water from the water discharge port.

[0005] In the present invention, based on the above observation and consideration of the mechanism, in a washbasin equipped with a washbasin and a water discharge device having a spout, a means capable of promptly draining or stopping remaining water after spouting. By providing a method for preventing scale from adhering to the surface of the basin in the basin, wherein the residual water is prevented from being supplied to the basin for a long time, and a water discharge device having a basin and a spout. In this regard, the present invention proposes a water-washing-prevention wash-out facility, characterized in that a means capable of quickly draining or stopping remaining water after spouting is provided.

In a preferred embodiment of the present invention, a water-repellent coating and / or a water-sliding coating is formed on the inner surface of the water discharge port of the water discharge device provided in the wash basin and / or the periphery thereof in order to prevent the above-mentioned water stain. A method for preventing scale from adhering to a basin in a wash basin, and a water-repellent coating and / or a water-sliding coating formed on and / or around a water discharge port of a water discharge device provided in the wash basin. To provide a scale for preventing scale adhesion. The portion where the water-repellent and water-slidable film is formed exhibits an effect of stopping water supplied from the portion where the water-repellent and water-slidable film is not formed at the boundary portion due to a difference in surface energy. In addition, the water where the water-repellent and water-slidable film is formed flows down without staying. Therefore, a water-repellent film and / or a water-slidable film is formed on the inner surface of the water discharge port and / or the periphery of the water discharge port of the water discharge device provided in the washroom equipment, so that the water drop falls from the water discharge port of the water discharge device. Residual water is less likely to stay at and around the vessel, and intermittent dripping of residual water is less likely to occur. Therefore, the basin is less likely to be stained with water.

According to the present invention, there is provided a water-discharge device provided in a washroom, characterized by containing a room temperature curable silicone, a room temperature curable fluorine resin, or a fluorine resin and a room temperature curable silicone. A water-repellent film and / or a water-slidable film formed on the inner surface and / or the periphery thereof having a water-repellent port, and a water-discharge port provided on a water-discharge device provided with the water-repellent device provided in the water-repellent facility; The present invention provides a method for preventing scale from adhering to the surface of a wash basin, including a step of applying the coating composition to an inner surface and / or the periphery thereof, and a step of curing the coating composition. By coating the hardening component with a room temperature hardening substance, it becomes possible to make it difficult for water scale to generate stains even on the existing basin surface.
