[0001] DISINFECTION SYSTEM FOR CERAMIC SANITARY WARE

[0002] Subject of the Invention

[0003] The invention relates to a disinfection system for the ceramic sanitary ware comprising at least one flush tank to enable the bowl of said ceramic sanitary ware to be flushed.

[0004] State of the Art

[0005] The electrolysis of the salt water is the process of separation of the dissolved salt in the water by way of electrical induction. The electrolysis is a chemical process where an electric current is used to dissolve or combine the ions in the water. The electrolysis of the salt water is important especially for the production of the hydrogen and chlorine gases. During the process, the following main anode reaction and the cathode reactions take place. As a result of these reactions, while the hydrogen and chlorine gases and / or the ions are released due to the electrolysis, the quantity of the hydroxide ions in the water increases, and thus the pH of the solution increases. This type of electrolysis process may be used also for killing the bacteria and the microorganisms in the water, because the released chlorine gas has disinfectant properties. However, since the hydrogen and chlorine gases that are possible to be released may be explosive, this process must be carefully controlled and such systems must be usually designed by taking the safety measures. Consequently, it is very important to continuously control the water and salt ratios for the electrolysis process and the electrolysis process itself.

[0006] The biofilm is a thin sticky layer secreted by the microorganisms on a surface where the microorganisms are embedded in a matrix surrounding them. The formation of a biofilm involves the formation of this special structure on a surface as a result of the assemblage of the microorganisms such as bacteria, algae, and fungi. The microorganisms generally attach to a surface after the stages of free floating in a liquid medium. This surface may be present on a pipe wall, tooth surface, implant, water pipes, medical devices, ship bodies, or in any moist or water-containing environment. The microorganisms produce a sticky matrix called extracellular polymeric substance (EPS) matrix that encases said microorganisms. This matrix, by preserving the biofilm structure, helps the microorganisms to stick to each other and to the surface. EPS secreted by the microorganisms forms the biofilm matrix. This matrix enables the microorganisms to remain attached to each other and stabilizes the biofilm structure. The biofilm matrix also regulates the interaction of the microorganism with their surroundings. The biofilm grows and develops in the course of time. The new microorganisms enable the biofilm to grow by joining the existing biofilm matrix. This process results in the expansion and the thickening of the biofilm. The biofilm formation may cause problems in various industrial, medical and environmental practices, because the biofilms allow the microorganisms to become more resistant to the antibiotics or disinfectants and allow them to cause various issues by damaging the surfaces. Consequently, controlling and preventing the biofilm formation is an important field of research and application in many industries.

[0007] In the laboratory studies, it was observed that the contamination remaining inside the toilet bowl persists following the first flushing action and that the flushing action does not entirely prevent the aerosol formation even when said flushing action is performed while the toilet seat lid is closed. It was further observed that the microbial contamination may occur and the biofilm formation may take place in the flush tank and the waterways due to the turbulence generated during the flushing or due to the water remaining inside the bowl taking the aerosol form. It was further observed that the water (dead water, still water, or standing water) kept standing especially in the areas like bathroom and toilet room where the contamination is excessive causes an increase in the existing pathogens and that said pathogens contaminate again the users, products, and the ambience through the flushing water. If the existing contamination contains a high quantity of pathogens, then there is the risk that said contamination may infect the persons using the products, the staff cleaning said products, and every other person present in the ambience.

[0008] Consequently, all the technical problems mentioned above have made it necessary to make an innovation in the relevant technical field. Object of the Invention

[0009] An object of the invention is to introduce a disinfection system, which enables the dead water standing inside the flush tank and / or in the toilet bowl and / or inside the toilet to be disinfected by means of a system generating electrolyzed water.

[0010] Another object of the invention is to introduce a disinfection system, which is capable of operating periodically and / or whenever desired and / or automatically based on the predetermined criteria.

[0011] Another object of the invention is to introduce a disinfection system, which enables the biofilm formation to be prevented in the waterways inside the flush tank and / or in the toilet bowl and / or in the toilet flushing system.
