Definitions

  • the present disclosure relates to the fields of personal and public hygiene, sanitation and disease prevention, and more particularly to the field of home and public self-cleaning toilet for better hygiene and sanitation.
  • Proper sanitation facilities promote health because they allow people to dispose of their waste appropriately. Absence of basic sanitation facilities can result in an unhealthy environment contaminated by human waste. Without proper sanitation facilities, waste from infected individuals can contaminate a community’s land and water, increasing the risk of infection for other individuals and contribute to the spread of many diseases/conditions that can cause widespread illness and death. Proper waste disposal can slow the infection cycle of many disease-causing agents. Inadequate waste disposal drives the infection cycle of many agents that can be spread through contaminated soil, food, water, and insects such as flies (www.cdc.gov/healthywater/global/sanitation/ toilets.html).
  • C. parvum (a parasitic protozoa) is the fourth most commonly identified cause of gastro-enteritis and thus diarrhea.
  • Toilets contaminated with infectious organisms are a recognized contact disease transmission hazard. It was indicated that toilet bowl water can remain contaminated for several flushes after the contamination occurs.
  • the persistence of pathogenic microorganisms in a public toilet (such as in a hospital emergency department waiting area), with aerosolization of pathogenic organisms during subsequent toilet uses by others, could pose a contact or airborne disease transmission risk.
  • pathogen persistence in a patient room toilet with subsequent aerosolization of microbes could pose an environmental contamination risk to patient care staff and other patients (David L. Johnson et al., 2018).
  • Baker et al. disclosed that although a single flush reduces the level of microorganisms in the toilet bowl water when contaminated at concentrations reflecting pathogen shedding, large numbers of microorganisms persisted on the toilet bowl surface and in the bowl water which were disseminated into the air by further flushes, risk of air-borne dissemination of microbes when flushing the toilet and the consequent surface contamination that may spread infection within the household, via direct surface-to-hand- to mouth contact. Some enteric viruses could persist in the air after toilet flushing and infection may be acquired after inhalation and swallowing (Baker et al. 2005).
  • flush toilet In the developed world, the use of flush toilet is a basic and daily matter, a person may use the toilet at home, or in public places such as working places, shopping centers, bars, restaurants, schools, public transportation stations, motorway stations and even on ships, planes, trains, etc.
  • public places such as working places, shopping centers, bars, restaurants, schools, public transportation stations, motorway stations and even on ships, planes, trains, etc.
  • going to the toilet in a public place and deciding not to use it and to "hold on” due to the poor sanitation and/or bad odor is a very familiar situation for all, especially for women.
  • Another familiar experience and a well-known situation is that in case of contagious diseases related with diarrhea or vomiting, it is highly likely for the disease to be spread among other members of the family, particularly among families with one or more children.
  • PCT application WO2011138798 discloses an invention for automatically cleaning toilet pots, which are preferably wall mounted toilet pots, either of WC type or Anglo-Indian type, but preferably of WC type.

  • flush toilet refers to a toilet that disposes of human waste (urine, feces, vomit, etc.) by using water to flush it through a drainpipe to another location for disposal, thus maintaining a separation between humans and their waste.
  • Flush toilets are a plumbing fixture and usually incorporate some form of a bend called a trap that causes water to collect in the toilet bowl to hold the waste and act as a seal against noxious sewer gases. Most flush toilets are connected to a sewerage system or to other forms of drainage systems.
  • flush refers to a sudden flow of liquids from a toilet cistern or water tank to the toilet bowl after which the toilet bowl contents empty and the bowl and cistern fills with water again. Further it may refer to the activation of such a flow of liquids and subsequent emptying and refilling the toilet bowl and cistern/water tank, usually by pressing a button (called a flush button), by pulling a string attached to a lever.

  • the present invention provides self-cleaning toilet and methods for maintaining toilet hygiene and fresh odor both in private residence and in public places which requires only little attention and resources, in other words, an occasional refill of toilet liquid cleanser. It is of extreme importance to state that the present invention discloses devices and methods where the water from the water supply system and toilet liquid cleanser are premixed to a unified mixture and stored as a mixture before flushing, therefore, it is the mixture that fills the toilet bowl.
  • the toilet liquid cleanser Upon defecation and/or urination the feces and urine mix immediately with the toilet liquid cleanser and water mixture, the toilet liquid cleanser at the same instant commence the process of disinfecting, and deodorizing the feces and/or urine, thus by the time toilet user flushes the toilet, the feces and urine related contamination levels and the unpleasant odor are reduced substantially. Flushing causes the stored mixture to flow into the toilet bowl mix with all (feces/urine and the bowl mixture of water and toilet liquid cleanser) augmenting the process of disinfecting, and deodorizing the feces and/or urine.
  • This initial step of disinfecting further augmented upon flushing is crucial in reducing the levels of above-mentioned contaminated aerosol, plume and droplets and surface contamination levels as a direct result.

  • the refillable container (124) is connected to the mixing volume (121) via a dose regulator (126).
  • a water line comprising a water tap (128) is also connected to the mixing volume (121).
  • the mixing volume (121) empties into the water tank (125) via an opening (129) in an exit pipe.
  • a float valve (not shown) is disposed within the water tank (102). When the liquid in the water tank (125) reaches a predetermined maximum level, the float valve (not shown) blocks exit of liquid from the mixing volume (121).
  • the float valve (not shown) drops, allowing the mixed water and toilet liquid cleanser to exit the mixing volume (121).
  • the mixed water and toilet liquid cleanser flows into the water tank (124)
  • water flows into the mixing volume (121) from the water line and toilet liquid cleanser flows into the mixing volume (121) from the cleanser pipe via the dose regulator (126).
  • the flow rate of the water is controlled by the system water pressure and the flow rate of the toilet liquid cleanser is controlled by the dose regulator (126). Flow of water and of toilet liquid cleanser will be stopped simultaneously by the float valve (not shown) when the float valve (not shown) has risen to a predetermined maximum level.
  • the bottom face of the refillable container (101) is not horizontal.
  • the bottom face slopes downward towards the cleanser pipe (111) so that the lowest portion of the refillable container (101) is the portion where the cleanser pipe (111) is attached to the refillable container (101). This increases the efficiency of the system, as it minimizes the amount of toilet liquid cleanser remaining in the refillable container (101) when the refillable container (101) ceases to work because it is empty, thereby increasing the efficiency of the system.

Abstract

L'invention concerne des toilettes auto-nettoyantes comprenant un récipient rechargeable destiné à stocker un nettoyant liquide pour toilettes en communication liquide avec un réservoir d'eau de toilettes. Le réservoir d'eau de toilettes reçoit de l'eau à partir d'un système d'alimentation en eau et un nettoyant de toilettes à partir du récipient rechargeable et comporte une soupape à flotteur contrôlant l'entrée d'eau et l'entrée de nettoyant de toilettes de telle sorte que, lorsque le niveau de liquide dans le réservoir d'eau est inférieur à un niveau prédéterminé, l'eau et le nettoyant de toilettes s'écoulent dans le réservoir d'eau, en se mélangeant avec le liquide dans le réservoir d'eau et, lorsque le niveau de liquide devient supérieur au niveau prédéterminé, l'entrée d'eau et de nettoyant de toilettes est arrêtée. Un régulateur de dose fournit un débit prédéterminé de nettoyant pour toilettes. L'eau entrante présente un débit d'eau prédéterminé et le nettoyant de toilettes entrant présente un débit prédéterminé, et un rapport prédéterminé de nettoyant de toilettes à l'eau est maintenu dans le réservoir d'eau.
