Embodiments of the invention relate to a floor cleaning device, in particular for use in a urinal or toilet environment.
In urinals that are used in a standing position, cleanliness of the floor may often be compromised. Therefore, it is common to clean the floor quite frequently in order to maintain a hygiene environment. However, maintaining a clean and hygiene environment in public urinals that are frequently used by individuals may be more difficult to accomplish. As a result, various solutions for assisting in cleaning of urinal floors have been proposed.
WO2013053712 for example describes a device for cleaning a standing surface for a urinal that includes a cassette-type insert that has a moveable standing surface for insertion in a recess in a floor below the urinal. A controllable drive device is provided for moving the standing surface past a cleaning device for cleaning the moveable standing surface.
Such solutions however are dedicated for cleaning the floor below a single urinal and require installation of a special standing mechanism, which may be costly in particular if applied in a public urinal environment that includes many urinals.
The following embodiments and aspects thereof are described and illustrated in conjunction with systems, tools and methods which are meant to be exemplary and illustrative, not limiting in scope.
In an embodiment there is provided a cleaning system for cleaning a floor of a restroom and comprising a wall coupled cleaning head and a docking site.
Wall coupling of the cleaning head in at least most embodiments may be taken to refer to connection and/or wiring of the cleaning head to power, liquid, pneumatic (etc.) sources required for its function. Wall coupling of the cleaning head may be via cables, pipes, electrical wires (or the like) that provide the cleaning head with access to incoming and outgoing fluid/liquid and power required for its operation.
In certain embodiments, the cleaning head may be of a self-driving ability, which may be facilitated via a driving means such as a motor implemented within the cleaning head.
In certain cases, the cleaning head may be movable via means other or in addition to self-driving—such as via an actuator or linear actuator, possibly with an integrated motor (such as an ‘actuator and motor drive’ and/or a ‘linear belt driven actuator’ available from various manufactures such as Macron Dynamics Inc. or the like). Such actuators may be coupled to the cleaning head coupling/connecting it to a wall of a restroom and may optionally be made to move along a rail (or the like) to urge movement of the cleaning head along a floor being cleaned together with tubes, pipes and the like required for its operation.
The docking site may be arranged to at least partially house the cleaning head when not in use, wherein the cleaning head being permanently connected to electrical cables, water source and drain or the like and hydraulic and/or pneumatic hoses.
In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the figures and by study of the following detailed descriptions.
Exemplary embodiments are illustrated in referenced figures. It is intended that the embodiments and figures disclosed herein are to be considered illustrative, rather than restrictive. The invention, however, both as to organization and method of operation, together with objects, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying figures, in which:
It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated within the figures to indicate like elements.
Attention is first drawn to
It is noted that throughout the present specification urinals may be mostly mentioned, however aspects of the present disclosure may be equally relevant to any other sanitary fixture within a restroom where cleaning may be periodically required in order to maintain a hygiene environment.
The restroom seen in this view includes an embodiment of a cleaning system 181 that is wall-coupled i.e. permanently connected to a wall of the restroom during all stages of use, possibly with assistance of a cable carrier or the like (not shown in the Fig.) for guiding and supplying a cleaning head 2601 of the system with necessary liquid, drainage, power (or the like) for its operation.
In certain embodiments the cleaning head may be of a self-driving ability for permitting the cleaning head movement back and forth along the floor of a restroom, here alongside the front wall to clean the floor below the urinals. Self-driven ability of a cleaning head may be facilitated in the various embodiments herein discussed by a driving means located within the head, such as an electric motor, that is arranged to drive the cleaning head possibly via wheels provide within the head along the floor.
In certain embodiments other possibilities may exist for moving the cleaning head along the floor. For example actuators may be coupled to a cleaning head for moving it along the floor (see, e.g.,
Cleaning system 181 may be arranged to perform a cleaning action of the floor periodically or according to certain triggers, such as detection of liquid such as urine and/or other dirt on the floor beneath or in a vicinity of one or more of the urinals. Detection of movement e.g. or users in a vicinity of a urinal or toilet to be cleaned, may be another example of such trigger. A cleaning action by a cleaning head of such system (as in
Attention is additionally drawn to
Cleaning system 182 may include a rail 20 along which it's cleaning head may be guided to maneuver along the floor, where here rail 20 may be placed to extend along front wall 12. Rail 20 may be arranged to lead, move, support and/or guide flexible electrical cables and hydraulic and/or pneumatic hoses required for cleaning actions performed by its cleaning head (such as drainage, power and liquid supply, or the like).
Such leading, moving, supporting and/or guiding may also or alternatively be facilitated by a cable carrier (such as carrier 71 later discussed) that may be designed to extend concealed within the restroom environment, such as at least partially concealed within one of the walls of the restroom. In addition, in this example the cleaning system is seen including indicators 22 that may take form of flashing lights and/or sound indicators (or the like) for waring users of the restroom when in use.

Cleaning system 183 may be arranged to provide support and/or guiding for flexible electrical cables and hydraulic and/or pneumatic hoses required for cleaning actions performed by its cleaning head (such as drainage, power and liquid supply or the like). Such support and/or guiding may also or alternatively be facilitated by a cable carrier (such as carrier 71 later discussed) that may be designed to extend towards the cleaning head of system 183 as it advances in its cleaning action.
Each cleaning system 183 may be arranged to operate independently from other cleaning systems 183 and may be suited to clean a floor region immediately beneath the urinal it is arranged to service. A possible advantage of the arrangement seen in
Attention is drawn to
Upon detection of urine, movement or other substances at a certain floor region, a controller of the cleaning system (not shown) in communication with the sensor may be arranged to trigger a cleaning operation of the floor region by cleaning system 184 that may be generally similar to any one of the embodiments disclosed herein.
Attention is drawn to
Cleaning head 26 may be arranged to include utilities such as: wheels 261, sensors 262, dry and/or hot air vents 263, a dirt and water vacuum 264, wipers 265, a brush 266 and a secondary vacuum 267. Cleaning head 26 may be arranged to interact with and clean the floor of a restroom beneath one or more urinals, and may be arranged to receive and/or discharge liquids and/or fluids required or removed during a cleaning operation via suitable conduits from or towards its docking site.
For example, cleaning head 26 may be arranged to receive flexible electrical cables and hydraulic and/or pneumatic hoses required for cleaning actions that it performs (such as drainage, vacuum actions, dirt removal, power and liquid supply, or the like). Such flexible electrical cables and hydraulic and/or pneumatic hoses may be guided via a cable carrier 771 that provides wall-coupling of the cleaning head and extends towards one of the walls of the urinal and/or towards the docking site where the cleaning head is designed to dock when not in use.
The cleaning head may be self-driven via e.g. a motor located within the head. A vacuum engine may be arranged to drain and suck liquids and/or dirt and the brush may also be connected to incoming liquid to enhance cleaning actions for efficient cleaning of the floor.
A controller may be provided within the cleaning head to control all cleaning actions and movements of the cleaning head, such as also sensors or communication with sensors within a cleaning system including cleaning head 26. Possibly, remote control of operations and/or monitoring of cleaning actions performed by the cleaning head may be provided via wire and/or via wireless communication such as via wifi (or the like).
Progress of the cleaning head along a floor being serviced may be along the directions marked by the opposing directed arrows provided in
In at least certain embodiments: fluids, liquids, electrical power (or the like) may be provided for constant operation of the cleaning system and/or head via conduits and/or cables that extend from an upstream source, a rail and/or docking site supporting or housing the cleaning system and/or head. Via such conduits and/or cables provision of power, water, drainage (etc.) may be facilitated. Possibly, such cables may be concealed and substantially not exposed.
Such permanent connection of a cleaning system and/or head to power and water/air conduits may permit heavy duty cleaning and long lasting operation without substantial human interaction. Such permanent connection in the provided example may be provided via the schematically illustrated cable carrier 771.
Attention is drawn to
Cable carrier 71 is here seen optionally extending from adjacent docking site 16 of the cleaning system where the cleaning head may be housed when not in use (while maintained connected to power, water, drainage (or the like)), and may be arranged to permanently connect cleaning system 185 and/or head 2605 to upstream supply and possible drainage sources. In certain embodiments, cable carrier 71 may be arranged to extend alongside a rail that guides the cleaning system and/or head during its operation. Preferably, cable carrier may be substantially concealed e.g. within a wall of the restroom as illustrated.
Attention is drawn to
The portions here seen within the wall include a cable carrier 711 here including a belt machining 919 that is driven by a motor 918. Attached to the belt machining in this example can be seen a hub 917 that is arranged to be moved by the belt mechanism back and forth along the wall in opposing directions (see arrows) generally parallel to the floor of the restroom.
The hub may be attached to a group of cables 916 located within the wall that may include: liquid, pneumatic, water, fluid, electrical conduits (or the like) required for operation of the cleaning head 2606 of the system. The hub may also be coupled via an opening 915 in the wall (e.g. a slit-like opening)—to the cleaning head for urging movement of the cleaning head along the floor and for coupling/connecting the cleaning head to the group of cables 916.
In the various cleaning system embodiments disclosed herein, docking of a cleaning head of a system may be against the wall and not necessarily within a wall. In addition, docking sites and/or cleaning heads of systems may be provided with a sanitizer/cleaning liquid container for assisting in sanitizing the floor during cleaning or regions within a restroom and/or portions of the cleaning system in between cleaning operations, such as sanitizing a cleaning head of the system in between cleaning operations.
Such systems may also be robotic e.g. without a conveyor belt or actuators for supplying liquids/fluids for performing a cleaning action. Hence such a robotic system may be equipped with internal supplies/resources required for its operation, e.g. water supply, drain container (e.g. for containing used liquid during a cleaning operation), sanitizer container (and the like)—instead of receiving supply of such substance from a conveyor belt. Such robotic systems may in addition be arranged when located within a docking site—to connect to docking ports within or associated with the docking site (e.g. a water source, drainage reservoir, electrical power, etc.) At the docking site the robotic head may be filled automatically with liquids and drain the drain container possibly automatically.
In certain embodiments, cleaning of the system's cleaning head (e.g. brush) may be performed, e.g. with water/sanitizer, when at the docking site—possibly also comprising a step of the drying such cleaning head part.
In at least certain embodiments, a system's cleaning head may include a cleaning member (e.g. brush, mop, or the like) that may be arranged to move during a self-cleaning operation of the cleaning head e.g. against the floor, while being supplied with cleaning substances (e.g. water, sanitizer, etc.). Such self-cleaning of the head's cleaning member may be performed without movement of the cleaning head along the floor (as in a normal cleaning operation). Cleaning substances used during such self-cleaning sequence may be vacuumed to a drain container (or the like).
In certain cases, such self-cleaning procedure may include urging the cleaning member to move against a dedicated rough surface (e.g. with relative sharp projections) aimed for assisting in the cleaning process of the cleaning member.
Attention is drawn to
Such ‘residential’ cleaning system 187 may be arranged to cooperate with a docking site inside the wall or a wall mounted docking site 160 as shown (being e.g. parallel to the wall) where the cleaning head 2607 of the system may be stored/parked vertically. Such parking within the docking site may be self-propelled by the cleaning head, which e.g. may self-advance to climb up into the docking site (possibly along a rail provided by the system/docking-site). In certain cases, the docking site may lower an arm member (or the like) aimed at coupling to the cleaning head and lifting same up to the docking site.
Such docking site may be connected to water/power/drain or battery and sanitizer container (or the like)—and/or system's cleaning head may be equipped with small containers that can connect and flush or refill liquids to or from ports the docking site with parked.
Such ‘residential’ cleaning system may accordingly include many features of system embodiments described herein, such as self-cleaning functionality of a cleaning member (e.g. brush/mop) of the cleaning head.
