Definitions

  • the invention relates to a method for operating a urinal according to the preamble of patent claim 1 and a urinal operating according to this method according to the subject matter of claim 4.
  • Another known method is to use a proximity sensor to determine when the urinal is being used and to flush the respective urinal only in this case.
  • this has the disadvantage that the urinal is only rinsed during periods of use, but that cleaning cycles do not take place. For example, when the urinal is not in use, it would be desirable to switch on one or more cleaning cycles in order to perform a kind of general cleaning, so to speak.
  • the disadvantage of the second known method is that there is always a constant amount of rinse water is released per use, which is also coupled with high water consumption.
  • the invention is therefore based on the object of developing a method for operating a urinal and a urinal operating thereafter such that less rinsing water is used with the same or superior cleaning action.
  • the invention is characterized by the method according to the subject matter of claim 1.
  • An essential feature of the invention is that an intelligent urinal is now created, the control of which is first communicated as to what fixed amount of consumption water may be consumed at all for a certain unit of time. This particular unit of time can e.g. 1 day, 1 week, 1 month or the like. This is how the controller is informed, e.g. for a period of 1 week, only a fixed amount of water, e.g. 300 1 to be allowed to consume rinse water.
  • the intelligent control provided according to the invention now keeps a record of the predetermined fixed amount of consumption water and measures the rinsing water per use and per cleaning cycle so that the predetermined fixed amount of consumption water is not exceeded for the predetermined period. It is provided in a development of claim 1 that the amount of water dispensed per rinse cycle can be changed. The change can take place, for example, depending on the washing event, namely whether a usage cycle takes place or a cleaning cycle.
  • rinse cycles e.g. the rinse cycle for total cleaning, regardless of whether a user uses the urinal or not.
  • Self-administration is therefore proposed with the subject matter of the invention, which always ensures that a predetermined total amount of water per unit time is not exceeded.
  • a rinse additive can also be mixed in with the rinse water, which is metered in according to the requirements.
  • the control according to the invention therefore relates not only to the metering of rinsing water, but also to the metering of a detergent in order to achieve a better cleaning effect with less water consumption.
  • a urinal which operates according to the method according to the invention accordingly provides that a proximity sensor acts on a microprocessor via a signal line in order to count the number of circuits of the proximity sensor.
  • the microprocessor controls a valve for metering the rinse water via a signal output and can also control a valve for metering the detergent.
  • the quantity of flushing water dispensed per flushing cycle is also calculated, the calculation being able to be carried out by determining in a calibration cycle which quantity of water is dispensed per unit of time at which valve position.
  • the amount of water released per rinse cycle is then subtracted from a predetermined total amount of rinse water and the amount of the amount of wash water dispensed per wash cycle is dimensioned such that the sum of the amounts of water dispensed over all wash cycles does not exceed the predetermined total amount of wash water.
  • the intelligent control therefore ensures that the amount of rinsing water delivered per rinsing cycle is added up and is dimensioned such that a total amount of rinsing water given for a longer period of time is not exceeded.
  • each wash cycle 1-8 was only shown with a single bar. It can be provided that each rinse cycle 1-8 consists of a large number of individual rinse cycles, e.g. 20 or more. It follows from this that the flushing cycles shown have been entered as representative of a larger number of flushing cycles.
  • the area of the rectangle which results from lines 9 and 10 would represent the total amount of water which must not be exceeded over the five days shown.
  • the integral over this area thus represents the specified total amount of water for the specified period (Monday to Friday).
  • a certain, fixed, per wash cycle 1 is made specified amount of water used, for example a water amount of 2 liters. After a certain number of flushes on Monday, it is then provided that a flushing cycle 2 takes place with larger amounts of water, for example 3 liters, in order to ensure better cleaning of the urinal.
  • a rinsing cycle 3 with a larger amount of water e.g. 3 liters should be provided in order to achieve a complete cleaning of the urinal at the beginning of the day.
  • the control then provides at the end of the cycle that a general cleaning in the sense of the rinse cycle 8 takes place.
  • the total over the area of all bars (rinsing cycles 1-8) may then be the specified amount of consumption water 30 (Area, delimited by lines 9, 10).
  • a urinal 22 operating according to the method according to the invention provides that the number of approaches with a microprocessor 13 are counted via a proximity sensor 11 via a line 12. The total amount of water to be consumed per unit of time is predetermined for the microprocessor 13 via a fixed value input 14.
  • a valve 17 is then opened and closed in accordance with the calculated values, the lines 19 of which are coupled to the rinsing water.
  • This rinsing water is introduced into the rinsing distributor 23 in the urinal 22 and can be distributed there via a ring line 24.
  • the detergent is metered in in an analogous manner, with either a valve 18 or a metering pump 21 being controlled via the control line 16. There can therefore be only one metering pump 21 or only one valve 18.
  • the detergent is dispensed into the urinal 22 via the line 20.
  • FIG 3 shows that the proximity sensor 11 acts via the line 12 on a counter module 25 which is coupled to the fixed value transmitter 27 via a line 26.
  • An input 31 for inputting the total amount of consumption water 30 is coupled to the fixed value transmitter 27.
  • the output of the fixed value transmitter 27 is coupled to the microprocessor 13 via a line 28.
  • the counter module 25 acts on the microprocessor 13 via the line 29 presented calculations and accordingly the valves 17,18 controlled via lines 15,16.
