Definitions

  • the present invention relates to a device for automatically controlling the operation of at least one washroom appliance such as a water faucet, soap dispenser, shower, urinal, etc., in particular the operation of a flow control valve of such an appliance, comprising:
  • Such a device is known from EP-A-0 487 977.
  • This European patent application discloses a toilet including an automatic flushing system actuated by an active infrared detection system.
  • the automatic flushing system can be put out of order by means of a remote control operation device, in particular when a maintenance person enters the toilet to clean it.
  • the remote control operation device comprises an infrared transmitter and the automatic flushing system itself a receiver for the infrared rays emitted by the remote control device. These infrared rays have to be emitted both to initiate and to stop the cleaning or maintenance function.
  • the power source for supplying the necessary electrical power to the automatic flushing device has not been specified.
  • the present invention is, however, especially directed to automatic control devices which are powered by means of a low voltage power source, in particular a battery. In such a case, the longevity of the battery is of great importance.
  • the cleaning function of the known automatic flushing device has the disadvantage of requiring additional energy, in particular the receiver for detecting the infrared rays emitted by the remote control.
  • US-A-5 313 673 discloses a sensor for a flushing device.
  • the sensor comprises an IR emitter and a light receiver and means for by-passing the sensing unit.
  • the means for by-passing the sensing unit are not activated by means of a push button but instead by means of a magnet.
  • An object of the present invention is therefore to provide a new automatic control device which can be put in a maintenance or cleaning function by means of a remote control device without making it impractical to still use a battery as power source.
  • the device according to the present invention is characterized in that said device comprises means for intermittently actuating and deactuating said receiver to reduce the power consumption thereof.
  • EP-A-0 410 001 discloses a water supply control device comprising a human being detecting system which is intermittently actuated to prevent quick consumption of the battery.
  • a human being detecting system which is intermittently actuated to prevent quick consumption of the battery.
  • the light-emitting means of the detecting system are intermittently actuated but not the light-detecting means.
  • the receiver is actuated at least once per second. In this way, the intermitted activation of the receiver will not be noticeable at all in practice for a person operating the remote control but the energy requirements can be kept to a minimum.
  • said appliance comprises a series of water nozzles in a wash fountain and connected to separate water supply valves.
  • An automatic wash fountain wherein the water valves and soap valves are individually controlled by a single control unit connected to different sensors is known per se from EP-A-0 574 372.
  • the wash fountain may contain either one common water valve or several water valves, one for each water nozzle. In the latter case, a number of passive infrared sensors are provided for detecting the presence of a user near the respective water nozzle of the wash fountain.
  • the person therefore has to deactivate the device for example by removing the battery or switching off the mains from the device or by closing for example the main water and/or soap supply.
  • This operation is relatively cumbersome, since the battery and the water and/or soap supply are normally well concealed to prevent vandalism and consequently not easily accessible.
  • closing the water supply of one wash fountain might require to close the water supply of an entire building.
  • the person may not forget to reinstall the battery in the device or to reopen the supply after maintenance.
  • Another important drawback is that when deactivating the entire wash fountain in any of the above described ways, the maintenance person can no longer take any water to clean the wash fountain and has therefore to provide the necessary supply of water.
  • maintenance means are therefore provided in the device which allow not only maintenance without requiring a cumbersome operation such as removing the battery from the device or closing the water and/or soap supply but which moreover permit to clean the wash fountain without having to provide a supply of cleaning water.
  • These maintenance means are arranged for preventing opening of all but at least one of said water valves during a predetermined period of time and for allowing opening of said water valves again after said predetermined period of time has lapsed
  • the maintenance signal can be generated in particular in response to the signal emitted by means of the remote control or optionally also in response to a signal generated by the device itself in particular in response to depression of a push button.
  • the maintenance person can simply give the required signal in response to which the overruling pulse is generated. In this way, actuation of said wash fountain is prevented during the predetermined period of time of for example two minutes so that during this period of time the presence of the persons in the neighbourhood of the device does not cause flow of water through the wash fountain, at least not through most of the water nozzles. No cumbersome operation is thus needed for allowing to clean the wash fountain. After this period of time, the person does not have to execute any actions, since the activation is automatically enabled and the device returns automatically to its normal operating condition.
  • the maintenance function enables to deactuate not all of the water valves but to maintain at least one water valve active so that the person may use the water flowing through this valve to clean the wash fountain.
  • all the water valves i.e. also the water valve(s) which were not inoperative during the initial phase, may be kept closed for a second predetermined period of time of for example 30 seconds, so that the wash fountain can be dried by the maintenance person. After this second period of time, the device automatically returns to its normal operating condition since the activation is automatically enabled.
  • said maintenance means include means responsive to said maintenance signal for opening said at least one water valve within said predetermined period of time and for closing said at least one water valve again, preferably within said period of time.
  • the maintenance person will thus automatically receive water to clean the wash fountain and will have at the end some time to dry it.
  • said maintenance means include means responsive to said maintenance signal for preventing opening of said at least one water valve of said series within said period of time but only after a predetermined delay period of time has lapsed.
  • this water valve may not automatically be opened but only in response to the presence of a person near the respective water nozzle, in particular the maintenance person who needs water.
  • the device according to the invention for controlling the operation of a series of washroom appliances comprising i.a. five water valves and five soap valves. It is clear that the device according to the invention can also be used for controlling the operation of one single washroom appliance, for example one water valve of a faucet, a shower, etc., a flush valve of a urinal, toilet, etc., or a soap valve for a soap dispenser, or for controlling the operation of a series of water valves or soap valves only. The device according to the invention can further also be used in soap dispensers, urinals, showers, ....
  • the device 1 includes an integrated circuit control chip 2.
  • the steps for performing the functions upon maintenance set forth in the flowchart of Figure 7 are performed under control of the control chip 2, more particularly by logic circuitry contained therein.
  • Other known functions for controlling the operation of the appliances to which the control chip 2 is connected are also performed under control of this control chip 2. These known functions are described in detail in EP-A-0 574 372, which is incorporated herein by way of reference.
  • the control chip 2 comprises several inputs and outputs to which different components are connected.
  • a first series of sensors 4-A to 4-E in particular infrared sensors, is connected to the control chip 2 through the intermediary of a first series of amplifier/filter circuits 5-A to 5-E, respectively.
  • This first series of infrared sensors 4-A to 4-E is provided for being positioned beneath corresponding water faucet or fountain nozzles.
  • a second series of infrared sensors 10-A to 10-E is connected to the control chip 2 through the intermediary of a second series of amplifier/filter circuits 11-A to 11-E, respectively.
  • This second series of infrared sensors 10-A to 10-E is provided for being positioned beneath corresponding soap dispensers.
  • the device 1 comprises further a battery level control circuit 3 connected to the control chip 2, the functioning and structure of which has also been described in EP-A-0 574 372.
  • Several outputs of the control chip 2 are connected to the I/O circuits 6, which in turn have outputs connected to a buzzer 7 and appliances of the device, more particularly actuation means 8 of an external device such as a hand dryer or towel dispenser, a series of water valves 9-A to 9-E respectively connected to the water faucets or fountain nozzles and a series of soap valves 12-A to 12-E respectively connected to the soap dispensers.
  • the device comprises further maintenance means.
  • the maintenance means comprise a remote control 14, provided for emitting a signal to a receiver 13.
  • the receiver 13 is connected to the control chip 2 via stabilising circuitry 15 provided for generating, upon receipt of the output signal of the receiver, a maintenance signal to be supplied to an input of the control chip 2.
  • the maintenance means further comprise a push button 16 or a similar switch incorporated in circuitry 17 which is also arranged for transmitting a maintenance signal to the control chip, in particular via conduit 18 to a different input of the control chip.
  • the receiver 13 and the circuitry 15 and 17 are connected to the VDD of the control chip 2 through separate conduits which have not been shown in Figure 1.
  • FIG. 2 there is illustrated a block diagram of a possible circuit of the remote control 14.
  • This circuit comprises i.a. a push button 40, an infrared light emitting diode L1, and a red indicator LED L2.
  • the LED L1 transmits a signal for the receiver consisting of a continuous series of pulses generated through the intermediary of transistor T1 and a pulse generating circuit including capacitor C1, resistors R1 and R2, diode D1 and an inverting Schmitt trigger IC1.
  • the output signal of this Schmitt trigger controlling the operation of transistor T1 and thus corresponding to the signal emitted by LED L1 is illustrated in Figure 3.
  • This signal consists for example of block pulses having a pulse width of 10 ⁇ sec and emitted at a frequency of 1/120 ⁇ sec.
  • Other details of the remote control will not be described as a person skilled in the art can deduce them from the block diagram and since it is possible to conceive various different kinds of other remote controls.
  • FIG. 4 A block diagram of the receiver, which will also be explained only in broad outline, is illustrated in Figure 4.
  • the pulsed signals emitted by the remote control 14 are received by a receiver diode DF and subsequently filtered and amplified by the different components of the receiver.
  • the resulting signals control the operation of transistor Q1 which transforms the signals from high impedance output to low impedance output signals of the receiver.
  • the receiver 13 is not activated all the time but each time only during a so-called "window" of for example 3 msec. This can be achieved under control of the control chip 2 which transmits for example every second an enabling signal via conduit 19 to receiver 13 to actuate it for 3 msec., i.e. for the duration of the enabling pulse.
  • the actual detection of the maintenance signal, i.e. of the pulses transmitted by the receiver to the control chip is preferably started only about for example 2 msec. after having activated the receiver, i.e. after the receiver has come back to an equilibrium.
  • the actual detection in the control chip 2 is in other words only carried out for the last third millisecond of the maintenance signal.
  • Deactivation of the receiver 13 is done in view of reducing the energy consumption of the device, i.e. for making it practical to use a low power voltage source such as a battery as power source. Indeed, due to the different filtering and especially amplifying elements of the receiver, it would otherwise require too much energy.
  • Control chip 2 and the components connected thereto and the various water and soap valves 9-A to 9-E and 12-A to 12-E are more particularly for example powered by a battery pack of about 9 Volts (not shown).
  • the output signal of the receiver 13 is not directly transmitted to the control chip but instead via circuitry or electronic components 15 for stabilising the signal again on the input of control chip 2.
  • a block diagram of these components is illustrated in Figure 5 even as a transistor T1 providing the enabling signal to the receiver under the control of a WASHWIND signal generated by the control chip 2.
  • the output WASH-INA of circuitry 15 corresponds to the above-defined maintenance signal transmitted to an input of the control chip.
  • circuitry 17 which enables to activate the maintenance function by means of the push button 16, is illustrated in Figure 6.
  • this circuitry 17 Upon depressing button 16, this circuitry 17 produces an output signal WASH-INS, corresponding also to the above-defined maintenance signal, starting from the VDD received from the control chip 2.
  • Both inputs of the control chip 2 for the maintenance signals (WASH-INA and WASH-INS) generated by means of the receiver 13 and circuitry 15 or by means of the push button circuitry 17 comprises preferably a Schmitt trigger producing for example on its output a voltage of 0 volt in case of an incoming maintenance signal between 0 and 1.5 Volts and a voltage of 5 Volts in case the incoming maintenance signal has a voltage of 3.5 to 5 Volts.
  • the maintenance function of the control chip is activated, i.a. an overruling signal is generated, upon receipt of the first positive pulse edge whereas for a maintenance signal received from the receiver 13 and circuitry 15, a number of for example four positive pulse edges are preferably to be received before activating the maintenance function.
  • the other water valves 4-B to 4-E and the soap valves 12-A to 12-E are actuated in the same manner.
  • the five sensors 4-A to 4-E control individual water valves of a wash basin, wash fountain, or the like in response to movement or presence of a user's hand close to water valves and the five infrared sensors 10-A to 10-E control individual soap valves of soap dispensers in response to movement or presence of a user's hand close to the soap valves.
  • the actuation means 8 are for example enabled after a predetermined time after one of the water valves has been activated. Alternatively, an additional sensor is connected to the control chip 2 for controlling the operation of the actuation means 8.
  • the maintenance person Before starting to maintain the washroom appliances, the maintenance person, provided with the remote control 14 generates a signal by means of the remote control 14. This signal is transmitted to the receiver 13, which upon receipt of the signal transmits a maintenance signal to the control chip. When an appropriate maintenance signal is detected by the control chip, the maintenance function is actuated as explained hereinabove. Referring now to Figure 2, the flowchart shows the sequence of operations and decisions performed by logic elements in control chip 2 to control the maintenance function.
  • variable GO WASH is first of all set to 1.
  • decision block 20 the value of the variable GO WASH is tested. If this value is 0, the test is performed again whilst in case the value is 1, buzzer 7 is activated for one second (operation block 21) to inform the maintenance person that the maintenance routine has been started.
  • a variable GO OFF is set to 1 (block 22) causing a reset of all the counters in the control chip and a termination of all the functions which are activated, i.e. the valves which were open at the start of the maintenance routine are closed and all of the valves are prevented from opening, at least by the normal automatic control functions by sensors 4A-4E and 10A-10E.
  • Interrogator 23 provides a delay of 1 second, i.e. the duration of the activation of the buzzer 7, and interrogator 24 provides a further delay of 2 seconds. After this delay, the GO WASH variable is reset in block 25 to 0.
  • the second possible routine for the maintenance function i.e. in case the variable WASH WAT is equal to 1, one of the water valves 9 is automatically opened to provide water for cleaning in particular the wash fountain. In a variant embodiment, it may be possible to open this valve only upon detection of the presence of a human body part adjacent the corresponding sensor 4.
  • the GO WASH variable is tested in block 33. If this variable has been set again to 1, by a new detection of the maintenance signal during the maintenance routine itself, the maintenance routine is prematurely ended by closing the open water valve (block 34) and by going directly to operation block 29, by which the buzzer 7 is activated for 3 seconds. This procedure is carried out for 90 seconds under control of interrogator 35.
  • the open water valve is closed under control of operation block 36 and the testing of the GO WASH variable is continued by interrogator 37.
  • the maintenance routine is prematurely terminated by going again directly to operation block 29 for activation the buzzer 7. This procedure is continued for 30 seconds through the intermediary of interrogator 38. After the delay period of 30 seconds, i.e. after a total period of 2 minutes, the maintenance routine is thus terminated in case no new maintenance signal has been given within this period.
  • the maintenance feature can further be applied to an automatic control system for urinals, toilets, etc. involving another operation mode, i.e. an actuation of the flush valves after the user has left instead of upon arrival of the user.
  • the control device disclosed in EP-A-0 574 372, the description of which is included herein by way of reference, comprises for example a dip switch X4 for making a selection between a wash fountain control and a urinal control.
  • the detection system does not have to be a passive infrared or another passive system but that also so-called active detection systems based on emitted infrared beams, sound waves, etc. can be used.
  • active detection systems based on emitted infrared beams, sound waves, etc.
  • these detection systems should however require as less energy as possible, for example by applying active and passive states.
  • the remote control may on the contrary require more energy as it is not continuously used. It can emit, as described, infrared signals or alternatively ultrasonic or electro-magnetic signals. These signals may be coded so that the maintenance routine can only be initiated by means of a suited remote control device.
  • the push button may for example be replaced by a magnetically operable switch as disclosed in US-A-5 313 673.
