Definitions

  • the present invention generally relates to systems and methods for cleaning sanitary fixtures, such as toilets.
  • Toilet cleaning products typically include a cleaning material formed into a water-soluble tablet. The tablet is then situated within either the toilet tank or toilet bowl such that when the toilet is flushed, some of the flushing water interacts with the tablet, dissolves some of the cleaning material, and dispenses the material into the toilet bowl.
  • Cleaning agents in the tablets can include chemicals that can degrade components of the toilet tank and toilet bowl and can be harmful upon direct contact with human skin.
  • Flush toilets can be classified into three general categories depending on the design of the hydraulic channels used to achieve the flushing action: non-jetted, rim- jetted, and direct-jetted toilets.
  • non-jetted bowl designs all of the flush water exits the tank into a bowl inlet area and flows through a primary manifold into the rim channel. The water can be dispersed around the perimeter of the bowl via a series of holes positioned underneath the rim. Although they can generally be inferior to other designs with respect to flushing power and efficiency, non-jetted bowls are well suited for the invention described herein since all of the dissolved cleaning fluid would be distributed around the rim of the bowl, achieving greater cleaning efficacy.
  • the bulk waste removal in toilets may be improved over non-jetted designs by incorporating "siphon jets.”
  • a rim-jetted toilet bowl the flush water exits the tank, flows through the manifold inlet area and through the primary manifold into the rim channel. A portion of the water is dispersed around the perimeter of the bowl via a series of holes positioned underneath the rim. The remaining water flows through a jet channel positioned at the front of the rim. This jet channel connects the rim channel to a jet opening positioned in the sump of the bowl, which is sized and positioned to send a powerful stream of water directly at the opening of the trapway.
  • the flush water exits the tank and flows through the bowl inlet and through the primary manifold.
  • the water is divided into two portions: a portion that flows through a rim inlet port to the rim channel with the primary purpose of achieving the desired bowl cleansing, and a portion that flows through a jet inlet port to a "direct-jet channel" that connects the primary manifold to a jet opening in the sump of the toilet bowl (see for example, US 8,316,475).
  • a sanitary fixture such as a toilet
  • a sanitary fixture may include a compartment between the toilet tank and the bowl for receiving and housing a cleaning product.
  • the compartment may situate the cleaning product in the flow path at any point downstream of the flush valve and upstream of the outlet ports of the toilet rim such that, with every flush, water flowing past the cleaning product injects cleaning material into the bowl via the rim outlet ports.
  • a perforated or slotted basket may hold the tablet within the compartment while simultaneously allowing water to flow from the tank, past the cleaning tablet, and into the toilet bowl.
  • the cleaning product may be tethered to a cap to permit the tablet to move freely in the water path with or without the use of a basket.
  • a cap can cover the compartment with a water-tight fit to seal the system from leaks.
  • the cap may further utilize a child-resistant design to prevent access by children and pets.
  • the visible portion of the cap can be color-matched to the surface of the sanitary fixture or otherwise designed to be aesthetically pleasing and/or unobtrusive to the eye.
  • a cleanser assembly for a sanitary fixture having a deck, a bowl, and a compartment defined in the deck in fluid communication with a waterway leading into the bowl, includes a housing mountable onto the deck over the compartment.
  • the housing is configured to receive a reusable or disposable cartridge containing the cleaning product for insertion into the compartment such that the cleaning product is introduced into the waterway and then delivered to the bowl.
  • the present invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, all as exemplified in the constructions herein set forth.

  • Compartment 120 may be sealed from the outside environment with cap 124.
  • Cap 124 can provide a water-tight or water-resistant seal with compartment 120 to prevent leaks or spray into or out of compartment 120.

To minimize the potential for leaks, a preferable position is on/under deck 114 of sanitary fixture 110. That is, compartment 120 may include a hole in deck 114 that extends from its top surface and into waterway 140 below. The hole may be formed using any process suitable for working with sanitary fixtures, which are typically made of porcelain. For example, the hole may be formed when the sanitary fixture is molded or after the fixture is molded, and before or after the fixture is glazed and fired, using a punching or drilling process.

As water erodes cleaning material 130, the force of gravity can cause the material to remain in waterway 140. Further, in contrast to cleaning puck 324, the section of cleaning puck 324b that extends above deck 114 can be sized and shaped to retain air compressed in waterway 140 when sanitary fixture 110 is flushed. This compressed-air chamber can help to ensure that water flowing down waterway 140 suitably interacts with cleaning product 130.

L'invention concerne un système de nettoyage, pour un appareil sanitaire (par exemple des toilettes), qui peut comprendre un ensemble de nettoyage, accueillant un compartiment formé dans la plate-forme de l'appareil en communication fluidique avec une voie d'eau conduisant à la cuvette. L'ensemble de nettoyage peut recevoir une cartouche contenant un produit de nettoyage destiné à être inséré dans le compartiment et à être introduit dans la voie d'eau. L'ensemble peut porter le siège et le couvercle de l'appareil et peut avoir un profil bas et une forme incurvée, qui complète la forme correspondante du siège et du couvercle, et présente un aspect équilibré qui permet à l'ensemble de sembler faire partie intégrante de l'appareil sanitaire.
