Definitions

  • the present invention relates to a combination of a urinal with a hand washing facility.
  • the waste water from the hand washing facility is used for flushing the urinal.
  • the hand washing facility and the urinal are in close proximity to each other and/or in physical contact with each other.
  • the hand washing facility is offset relative to the urinal so that the imaginary plane as defined by the center plane running vertically through the urinal, i.e. from top to bottom - preferably the vertical symmetry plane and/or the vertical plane defined by the outlet/opening for flushing the urinal and the discharge opening of the urinal - is positioned at an angle relative to the imaginary plane as defined by the center plane running vertically through the hand washing facility - preferably the vertical symmetry plane and/or the vertical plane defined by the faucet and the drain of the hand washing facility - wherein said offset angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, preferably between 40° and 60°.
  • said imaginary vertical (symmetry) planes of the urinal and the hand washing facility, respectively coincide with the direction of use by a user of the urinal and the hand washing facility, respectively.
  • said orientation of a user in regard to the urinal is offset relative to the orientation of a user in regard to the hand washing facility wherein said offset angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, preferably between 40° and 60°.
  • two or more of said combinations of a urinal and a hand washing facility are used in a restroom, preferably in a public restroom.
  • the combination according to the present invention is used in private restrooms, in particular private restrooms in transportation devices, in particular RVs, camping wagons, busses, or in maritime applications, in particular on boats or other vessels.
  • the combination according to the present invention is also used in public restrooms, wherein the public restroom is selected from the list comprising: public transportation venues, e.g. railroad stations, airports or highway restroom facilities; large vessels or boats, hotels, restaurants, conference facilities; public buildings, in particular museums, exhibitions, movie theatres, art houses, government buildings, schools, universities.
  • German utility model DE 200 07 812 discloses a combination of a hand washing facility with a urinal that is characterized by a single water inlet (the faucet of the hand washing facility) and a combined discharge for the waste water from both the hand washing facility and the urinal.
  • the hand washing facility is arranged directly above the urinal, i.e. the direction of use for the hand washing facility coincides with the direction of the use for the urinal.
  • DE 197 04 452 An alternative embodiment of a combination of a hand washing facility and a urinal (together with a water storage facility) is disclosed in DE 197 04 452 .
  • the facility disclosed therein is meant to be installed in a guest bathroom of a house using the inlet and discharge plumbing already present in such a guest bathroom.
  • an alternative embodiment is also disclosed showing the hand washing facility arranged perpendicular to the urinal (see Figures 4 and 5 of DE 197 04 452 ).
  • a common problem of all known embodiments of a water-saving combination of urinal and hand washing facility is that the geometry is such that the direction of use for the urinal and the direction of use for the hand washing facility coincide, i.e. the user remains in the same position for using urinal as for using the hand washing facility. While this may be a suitable and acceptable geometry for use in a private bathroom or in a guest bathroom, this setting is not acceptable for a public restroom in which urinals will typically get soiled and, the least for hygienic reasons, a potential user of urinal will not be inclined to use the hand washing facility while being potentially in proximity or even physical contact to the urinal.
  • an object according to the present invention is to provide a setting comprising urinal and hand washing facility that is water-saving and will be acceptable to potential users of public restrooms.
  • the present invention relates to a combination of a urinal with a hand washing facility.
  • the waste water from the hand washing facility is used for flushing the urinal.
  • the hand washing facility and the urinal are in close proximity to each other and/or in physical contact with each other.
  • the hand washing facility is offset relative to the urinal so that the imaginary plane as defined by the center plane running vertically through the urinal, i.e. from top to bottom - preferably the vertical symmetry plane and/or the vertical plane defined by the outlet/opening for flushing the urinal and the discharge opening of the urinal - is positioned at an angle relative to the imaginary plane as defined by the center plane running vertically through the hand washing facility - preferably the vertical symmetry plane and/or the vertical plane defined by the faucet and the drain of the hand washing facility - wherein said offset angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, preferably between 40° and 60°.
  • said imaginary vertical (symmetry) planes of the urinal and the hand washing facility, respectively coincide with the direction of use by a user of the urinal and the hand washing facility, respectively.
  • said orientation of a user in regard to the urinal is offset relative to the orientation of a user in regard to the hand washing facility wherein said offset angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, preferably between 40° and 60°.
  • the urinal of the present invention is to be understood to be any container or receptacle that is suitable for receiving urine. No limitations exist in regard to the shape and/or the materials of said urinal.
  • said urinal is suitable for being mounted onto a wall and comprises suitable plumbing.
  • the urinal preferably comprises at least one opening or outlet or orifice through which water can be dispensed onto the inside of the urinal, i.e. the area that is exposed to the urine.
  • said opening or orifice is also referred to as "opening/outlet for flushing the urinal”.
  • At least part of the liquid used to flush the urinal is waste water from the hand washing facility of the present combination of a urinal with a hand washing facility.
  • water from other sources than from said hand washing facility may be used in addition to waste water from said hand washing facility. It is also in the scope of the present invention that this at least one additional source of water is a fresh water source.
  • the present invention also relates to an embodiment in which waste water from the hand washing facility is stored in a storage device prior to being dispensed into the urinal.
  • any dispensing process of water into the urinal is controlled by means of a control unit, for example a central processing unit, a timer, a central control unit or any other conceivable controller.
  • a control unit for example a central processing unit, a timer, a central control unit or any other conceivable controller.
  • the urinal of the present invention also has at least one discharge unit suitable for discharging urine and any (waste) water used for flushing the urinal.
  • the urinal has one imaginary plane that is defined by the center plane running vertically through the center of the urinal, i.e. from top to bottom.
  • said plane is the vertical symmetry plane and/or the vertical plane defined by the outlet/opening for flushing the urinal and the discharge opening of the urinal.
  • said plane is perpendicular to the intended positioning (imaginary line through shoulders and head) of a user of the urinal.
  • said imaginary plane of the urinal coincides with the vertical symmetry plane that would be, in this case, a mirror plane (see, for example, Figure 1 ).
  • a similar imaginary vertical plane can be defined for the hand washing facility.
  • said imaginary vertical plane runs through the center of the hand washing facility - preferably the vertical symmetry plane and/or the vertical plane are defined by the faucet and the drain of the hand washing facility.
  • said imaginary vertical (symmetry) planes of the urinal and the hand washing facility, respectively coincide with the direction of use by a user of the urinal and the hand washing facility, respectively,
  • the urinal and the hand washing facility are offset relative to each other as defined by an offset angle between the vertical (symmetry/center) plane of the urinal and the vertical (symmetry/center) plane of the hand washing facility, wherein said angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, further preferably between 40° and 60°.
  • said offset angle is between 20° and 80°, preferably between 30° and 75°, further preferably between 40° and 70°, further preferably between 40° and 60°
  • the hand washing facility in accordance with the present invention comprises at least one dispensing unit for dispensing fresh water, preferably a faucet. Said hand washing facility furthermore comprises at least one discharge unit for discharging the spent water that is collected in a container/receptacle of the hand washing facility.
  • the waste water and/or freshly dispensed water from the dispensing unit is directed from said discharge unit of the hand washing facility to the opening/outlet for flushing the urinal.
  • the natural pull of gravity is used to transport the waste water from the hand washing facility through the discharge unit of the same to the opening/outlet for flushing the urinal.
  • a pump or a pumping means may be used, in addition to or instead of the gravitational pull, to transport water from the discharge unit of the hand washing facility to the opening/outlet for flushing of the urinal.
  • a combination of gravitational pull and a pump is used.
  • the plumbing of the urinal in addition to waste water from the hand washing facility (or freshly dispensed water running through the hand washing facility), the plumbing of the urinal may be arranged so that also fresh water from a separate fresh water line/source is added for flushing the urinal via the opening/outlet. Said fresh water may also be run through the hand washing facility at times no user uses said hand washing facility.
  • two or more such openings/outlets for flushing the urinal may be provided, for example two openings/outlets on opposite sides of the urinal, to more thoroughly flush the inside of the urinal.
  • one or more or all of these two or more openings/outlets are connected with the discharge unit of the hand washing facility.
  • the waste water from the hand washing facility is discharged through the discharge unit of the hand washing facility via the urinal through the discharge unit of the urinal.
  • the hand washing facility is arranged adjacent to the urinal but not in direct (or immediate) physical contact with the same.
  • the waste water (or freshly dispensed water from the faucet) of the hand washing facility is still directed, for example via separate plumbing, from the discharge unit of the hand washing facility to the opening/orifice for flushing the urinal.
  • the distance between the two outer surfaces of the urinal and the hand washing facility, respectively, that are the closest to each other is not more than 40 cm, preferably not more than 30 cm, further preferably not more than 20 cm, further preferably not more than 10 cm, further preferably not more than 5 cm.
  • the hand washing facility and the urinal are adjacent to each other but not in direct physical contact, and are separated from each other by another unit, for example a separation unit that may, preferably, comprise the faucet.
  • a separation unit that may, preferably, comprise the faucet.
  • FIG 3 An embodiment in which a spacing unit is arranged in between the urinal and the hand washing facility is shown in Figure 3 .
  • the faucet is not part of the hand washing facility but part of said spacing unit.
  • Such an arrangement may be seen as particularly advantageous for emphasizing the separation between urinal and hand washing facility.
  • two or more, further preferably four or more, further preferably five or more, further preferably eight or more, further preferably ten or more of the combination units of urinal and hand washing facility and urinal are placed next to each other in the same room.
  • An example of such a preferred embodiment is shown in Figure 2 .
  • Placing a plurality of combination units of urinal and hand washing facility next to each other would be a typical setting in a public restroom, for example in airports, train stations, government buildings, office buildings, schools, universities, restaurants, cultural venues, sports stadiums and the like.
  • One particular advantage of the geometry of the present invention i.e. the staggering or "off-setting" of the hand washing facility (which is nevertheless adjacent to the urinal) relative to the urinal allows to place a plurality of these units next to each other, without having to provide physical boundaries between the same, for example walls or screens, since the field of view of a person using the urinal does not coincide with field of view of a potential user of an adjacent urinal while, at the same time, the field of view of a person using the hand washing facility does not coincide with the field of view of a potential user of the urinal of another (adjacent) unit.
  • the respective fields of view severely cross in case the urinal and the hand washing facilities are arranged at a 90° angle relative to each other in such an array of a plurality of combination units.
  • two, three, four or more, preferably four, combination units of urinal and hand washing facility are arranged around a column, pole or post.
  • urinal and hand washing facility are provided as two separate building units that can be exchanged or replaced independently from each other (see, for example, Figure 1 ).
  • This embodiment has the advantage of flexibility, superior design possibilities and ease of maintenance/repair.
  • urinal and hand washing facility are provided as an integral unit (see Figure 5 ). While this arrangement is less flexible (i.e. if either the urinal or the hand washing facility is defective, the entire unit needs to be replaced), however, said arrangement is cheaper to manufacture and easier to install.
  • such integral unit is made from one main material, in particular a ceramic material or a plastic material or a composite material. It is particular preferred that such an integrated unit is cast or extruded or pressed.
  • a sensor is provided in the urinal, which detects the onset and/or the end of a urination process.
  • the sensor and pertinent control unit Preferably, once the sensor and pertinent control unit have determined that the urination process is finished, for example after a certain predetermined time interval after the last sensing of urine inflow, the water dispensing of the hand washing facility, preferably through the faucet, is automatically initiated.
  • the flushing of the urinal and/or the operation of the water dispensing unit of the hand washing facility is preferably subject to at least one control unit.
  • Said control unit preferably comprises at least one sensor.
  • a suitable sensor would be, for example, a sensor for liquids, a weight sensor, a sensor for urea, a pressure sensor and/or a water level sensor.
  • the sensor permanently detects influx of urine and sets a certain internal trigger after, for example, three or more seconds of urine influx.
  • a second signal may be triggered, after the triggering of the first signal, in case no influx of urine is detected for a certain period of time, for example for three seconds.
  • a control unit then starts the dispensing of fresh water in the hand washing facility, preferably, by operating the faucet of the hand washing facility, thus enticing or facilitating the washing of hands by the user of the urinal.
  • said "automatic" dispensing of water is stopped after a predetermined time interval, for example five seconds.
  • the hand washing facility in addition to this preferred embodiment of automatic water dispense triggered by a use of the urinal, the hand washing facility also has a sensor for starting the dispensing process of water as is common for modern hand washing facilities. Thereby, usage of the hand washing facility is also possible without using the urinal.
  • the preferred embodiment of triggering the dispensing of water by usage of the urinal has the added advantage of increased hygiene since the user of the urinal is enticed to wash his hands.
  • the combination unit of urinal and hand washing facility in accordance with the present invention has the following advantages over urinals and hand washing facilities known from the art, in particular urinals used in a public restroom setting.
  • the waterless urinal does not save or reuse the water from the separate hand washing facility
  • the present invention provides the same water-saving effect as the so-called waterless urinals, however, has the added advantage of flushing the urinal thus allowing to cut or dispense the use of chemicals to deal with odor and other issues relevant for the hygiene of a urinal.
  • the combination unit of urinal and hand washing facility of the present invention provides the potential for considerable space saving since less hand washing facilities need to be provided in the public restroom overall (hand washing facilities still need to be provided for the toilets also provided in the restroom).
  • the set up of the present invention also minimizes the plumbing needed and therefore the operation and maintenance costs for the restroom.
  • the specific geometry of the present invention allows, for the first time, to provide a large number of combination units of urinal and hand washing facility in a public restroom setting since the users will experience the same (semi)privacy they expect from public restrooms with separated urinals and hand washing facilities.
