Definitions

  • This invention relates generally to self-cleaning rooms, and more particularly concerns a system for cleaning rooms with cleaning fluid sprayed from a spray source mounted on an armature that extends from a wall or partition during cleaning into a room to a desired proximity to a selected surface to be cleaned.
  • Spray mechanisms for cleaning a room can be usefully employed in the walls or ceiling of the room to allow selected surfaces in the room to be cleaned manually or automatically.
  • such systems are typically ineffective and/or inefficient unless the spray mechanisms are in sufficiently close proximity to the surfaces to be cleaned.
  • a spray from a ceiling area is used for cleaning fixtures and walls of a room.
  • such a system is typically impractical, due to the difficulty of achieving conservation of cleaning fluid and sufficient cleaning fluid pressure in sufficient proximity to the surfaces to be cleaned.
  • a cleaning system for a self-cleaning room in which a desired proximity between a spray source and a surface to be cleaned is achieved by moving spraying source into the room, instead of, or in addition to, moving the surfaces to be cleaned, such as by rotation of the walls of the room. It would be desirable to thus allow cleaning of an isolated fixture located on a wall which is non-contiguous with a rotating wall carrying a fixed spray source, by a spray source moved into proximity with the isolated fixture.
  • the present invention provides for a cleaning system for self-cleaning rooms in which a spray source is mounted on a spring-loaded, movable armature that is extended from a self-closing cabinet mounted to a wall or partition into the room in close proximity to a selected cleaning surface during cleaning.
  • the present invention accordingly provides cleaning system for a self-cleaning room having at least one wall and one or more selected surfaces to be cleaned, and cleaning means for cleaning the selected surfaces.
  • the cleaning means includes spray means for spraying cleaning fluid under pressure on the selected surfaces to be cleaned, and the spray means is mounted on at least one armature hingedly mounted to a wall or partition of the room, to extend the spray means to a desired distance from the selected surface to be cleaned.
  • the cleaning system can be mounted to a fixed wall or partition of a room to be cleaned
  • the room to be cleaned includes a rotatable wall
  • the cleaning chamber, spray source and armature can be mounted to the rotatable wall
  • the cleaning means preferably includes rotatable plumbing for rotation with the rotatable wall.
  • Fig. 4 is an enlarged sectional view of the cleaning system of the invention similar to that of Fig. 3, showing the cleaning system in a folded configuration;
  • the present invention provides a cleaning system for a self-cleaning room that is suitable for cleaning any selected surfaces in a room, including isolated fixtures which can otherwise be out of reach of fixed spray sources.
  • the flexible, high pressure tubing also functions as a means for extending the articulated armature when cleaning is to be initiated and during cleaning, because the force of the high pressure cleaning fluid carried in the tubing during cleaning rigidifies and extends the tubing and the associated boom arm member, acting against the retracting force of the return spring, and opening the cabinet cover panel.
  • the tubing again relaxes and can be folded by the return spring along with the boom arm member into the cabinet.
  • the cover panel closes, concealing the mechanism of the cleaning system from view.
  • a drying system including a blower and heater for introducing heated air into the room area to dry fixtures and wall surfaces after cleaning may optionally be included in the cleaning system. Vents (not shown) can also be provided for escape of the heated, moist air from such a drying system, or to merely assist in drying of the room area by normal evaporation where no heater or blower are provided.
  • a force air drying system is not essential for adequate drying, particularly as the cleaning fluid may be heated to naturally flash and evaporate during and immediately following cleaning.
  • the cleaning fluid used with the cleaning system of the invention currently preferably comprises an aqueous solution which may include suitable detergents, common cleaning solvents, wetting agents and sanitizing agents which can be dispensed into the fluid supply lines as desired during cleaning.
  • the cleaning fluid supply lines 68 connected to the high pressure flexible tubing preferably includes rotatable plumbing joints 69.
  • the cleaning system of the invention implemented in a room with rotatable wall sections is identical to that described with respect to Figs. 1, 3 and 4.
  • the articulated armature includes a cantilevered bracket portion 136 affixed to a wall plate 138 mounted to a portion of the partition panel, and a boom arm member 140 hingedly mounted to the distal end 142 of the bracket portion of the armature, at the pivot 144.
  • the boom arm member is preferably movable between a first folded position extending substantially vertically from the bracket portion, and a second position extending outward from the partition panel substantially horizontally. The boom arm member preferably abuts the end of the bracket portion in the second horizontal position, to lock in the horizontal position without dropping further.
  • Means 146 for retracting the boom arm from the second extended horizontal position are also preferably provided, and in a preferred embodiment comprises a coil spring 148 connected between the wall plate and a point 150 on the boom arm intermediate the distal 152 and proximal 154 ends of the boom arm.
  • the wall plate includes two articulated armatures, and with suitable lateral offsetting of the articulated armatures where the armatures might otherwise hinder each other, the wall plate can also readily accommodate additional articulated armature mechanisms.
  • Means 164 for cleaning the selected surfaces in the room area to be cleaned are also preferably mounted to the articulated armature, to swing out when cleaning is initiated, and to be retracted when -.he cleaning system is not in use.
  • the cleaning means preferably comprises a flexible tubing 166 capable of carrying cleaning fluid under high pressure, connected to a fluid supply line 168, and mounted to the boom arm member by one or more bracket members 170 preferably allowing the tubing to slide and flex as the boom arm member is extended and retracted.
  • a toilet 121 is mounted to a non- rotatable wall section, while a sink 123 and a lavatory 120 are mounted on rotatable wall sections.
  • these fixtures can be cleaned by fixed wall spray heads 125 mounted in the fixed and/or rotatable wall sections.
  • it can also be advantageous to provide the movable spray arm cleaning system of the invention in individual partition panels or in cubicle partition panels in order to reach selected wall or fixture surfaces which may be otherwise difficult to clean effectively with a rotatable wall self-cleaning system.
  • the cleaning system of the invention provides for mechanism for minimizing the distance between a spray source and surfaces to be cleaned in a self-cleaning room by mounting a spray source to a self-retracting, movable armature that is extended from a self-closing cabinet into a self-cleaning room in close proximity to a selected cleaning surface during cleaning.
  • the cleaning system of the invention allows cleaning of isolated fixtures located on a wall which is non-contiguous with a rotating wall carrying a fixed spray source, and other surfaces which would otherwise be too distant for effective cleaning by a fixed wall spray, by moving a spray into proximity with the isolated fixture or other selected surface to be cleaned.

Abstract

Un système de nettoyage (10, 110), destiné à des locaux auto-nettoyants comportant au moins un mur (14, 114), présente une source (74, 174) de produit d'aspersion montée sur un châssis mobile (32, 132) qui se déploie, à partir d'un coffre à fermeture automatique (56, 156), dans le local, tout près d'une surface à nettoyer, pendant son fonctionnement. Ce châssis est monté par des charnières sur un mur (14, 114) ou une cloison (122) pour amener la source (74, 174) de produit d'aspersion à distance désirée d'une surface à nettoyer. Dans un mode de réalisation préféré, cette source (74, 174) et ce châssis (32, 132) sont montés dans une chambre de nettoyage à fermeture automatique (56, 156) fixée sur un mur (14, 114) ou une cloison (122). Le châssis (32, 132) comporte aussi de préférence un ressort (48, 148) destiné à le replier dans la chambre de nettoyage (56, 156). Il existe aussi un mécanisme permettant d'ouvrir le volet (58, 158) de la chambre de nettoyage (56, 156) et de déployer le châssis (32, 132) et la source de produit d'aspersion (74, 174) dans le local pendant le nettoyage.
