Definitions

  • the invention relates to an arrangement for detecting resource usage in a dispenser, in particular in a washroom dispenser, a dispenser for dispensing a resource, in particular a washroom dispenser, and a method for detecting resource usage in a dispenser, in particular in a washroom dispenser. Further, the invention relates to a system and a method for monitoring resource usage in at least one dispenser, in particular in at least one washroom dispenser.
  • Dispensers, sensors, and methods for detecting and monitoring resource usage in a dispenser, in particular in a washroom dispenser are known, for example, from WO 2015/086055 A1 , WO 2015/010143 A1 , WO 2015/165731 A1 , WO 2014/035307 A1 , WO 2014/027030 A2 , WO 2013/016748 A1 , WO 2013/016747 A1 , WO 2013/113129 A1 , WO 2006/065514 A1 , WO 2006/065515 A2 or WO 2005/065509 A1 .
  • an arrangement for detecting resource usage in a dispenser comprising a sensor for detecting resource usage having an emitter and a receiver of radiation adapted to detect the absence of a resource by receiving via the receiver radiation emitted by the emitter, a counter adapted to count portions of the resource dispensed by the dispenser, and a control unit adapted to adjust counter data depending on a signal received from the sensor for detecting resource usage.
  • the arrangement according to the invention is suitable for detecting resource usage in a dispenser, in particular in a washroom dispenser.
  • the resource of which the usage can be detected can be a washroom product, in particular a washroom hygiene product, such as cleansing agent, like soap, disinfecting agent, moisturizing lotion, fragrance, or the like.
  • the resource can be provided as a fluid, like liquid or gas, or as a foam or gel, for example.
  • the dispenser is suitable for dispensing a resource, in particular a washroom product, preferably in discrete portions.
  • the dispenser can be a dispenser for dispensing washroom hygiene products, which is wall-mounted and/or integrated into washroom furniture.
  • the dispenser can be integrated in a self-cleaning toilet for dispensing a cleansing and/or disinfecting agent, for example.
  • the amount of resource dispensed in a single discrete portion is known and/or can be predetermined and/or is dependent on the kind of resource used and/or can be adjusted.
  • a resource which is impermeable to radiation, at least to a certain extent and in particular to radiation as further detail below.
  • a container containing the resource is permeable to radiation, at least to a certain extent and/or in the area in which detection takes place, and in particular to radiation as further detail below.
  • the detection principle according to the invention is based on the principle to detect the presence of resource when the receiver does not receive radiation emitted by the emitter (due to the presence of resource between the emitter and the receiver) and to detect the absence of a resource when the receiver does receive radiation emitted by the emitter (due to the absence of resource between the emitter and the receiver).
  • the container of the resource preferably is permeable to radiation, as described above. Therefore, a container not containing resource in the area of detection (i.e. in the detection path between the emitter and receiver of radiation), preferably will not prevent the receiver from receiving radiation emitted by the emitter.
  • the detection principle can also be described as a photoelectric barrier, which detects the absence of resource when radiation is received and the presence of resource (or an obstacle), when the receiver does not receive radiation emitted by the emitter.
  • the sensor is further adapted to generate a signal depending on the detection of the presence and/or absence of resource.
  • the arrangement further comprises a counter, which is adapted to count portions, preferably discrete portions, of the resource dispensed by the dispenser.
  • the dispenser comprises a dispensing mechanism, which can be activated via an actuation element and/or in a contactless way.
  • the dispenser can comprise a dispensing mechanism, which can be activated by a user via an activation element, like a lever, in order to dispense a portion of the resource.
  • the dispenser can comprise a contactless or hands-free dispensing mechanism.
  • the dispensing mechanism can be activated by the detection of a user via a proximity sensor and then dispense a portion of the resource.
  • the dispensing mechanism comprises a drive, for example an electric drive, to dispense a portion of the resource.
  • the counter can be adapted to work with a dispensing mechanism, which is activated by the user, and/or with a hands-free dispensing mechanism.
  • the counter can be adapted to increase the counter data each time the dispensing mechanism is activated (via an activation element and/or via the drive).
  • the arrangement further comprises a control unit is adapted to adjust counter data depending on a signal received from the sensor for detecting resource usage.
  • An adjustment of counter data can be, for example, a correction of the number of portions counted and/or and overwriting of the number of portions counted with a predetermined value, preferably a number of portions corresponding to the signal received from the sensor.
  • the position of the sensor in relation to a resource container or resource supply is known.
  • the resource level corresponding to the position of the sensor is known.
  • the remaining amount of resource is known and/or can be estimated, once the sensor has changed from detecting the presence of resource to detecting the absence of resource.
  • the remaining amount of portions of resource is known.
  • the control unit is adapted to correct and/or overwrite the counter data with the amount or number of portions corresponding to the remaining amount or number of portions, when the sensor has changed from detecting the presence of resource to detecting the absence of resource.
  • control unit being adapted to correct and/or overwrite the counter data is that during operation of the dispenser, the counter data can be or become inaccurate.
  • the amount dispensed by the dispensing mechanism can vary. For example, not the whole predetermined amount of resource is dispensed in a portion, but only a part of the portion gets dispensed. This can happen, for example, when foam has formed in an otherwise liquid soap. Therefore, dispensers which detect the usage of a resource by counting dispensed portions only, can lead to inaccurate or unreliable indications of the remaining amount of resource in the dispenser and/or the remaining amount or number of portions to be dispensed.
  • a more accurate and more reliable detection of usage of the resource is possible.
  • a further advantage of the arrangement according to the invention is that, in particular in case the position of the sensor in relation to the resource container and/or the resource level at the position of the sensor is known, the number of portions dispensed to reach the resource level corresponding to the sensor position, can be determined.
  • a new detection cycle is started.
  • the counter data is set to a predetermined value, preferably zero portions.
  • the predetermined value corresponds to a reference and/or target value. Further preferably, the predetermined value depends on the kind of resource and/or the kind of resource container provided.
  • the correct and/or desired resource is present in the dispenser or whether the counter data indicates that a different resource is present in the container.
  • characteristic lines for different resources and/or different resource containers are available in the control unit and or an external communication unit, in order to allow for a comparison of the counter data with the target value.
  • Such a check or verification of the kind of resource used can be particularly preferred in areas, where the provision of a certain resource is prescribed. For example, when a certain dispenser is meant to dispense a disinfecting agent, but the counter data indicates that moisturizing lotion is provided instead, a warning signal can be generated.
  • the arrangement can comprise two or more sensors, which preferably are arranged at different positions, such that their positions correspond to different resource levels.
  • a first sensor corresponding to a higher resource level can primarily be used to detect which resource and/or which resource containers is provided (by a comparison of the counter data with a target value)
  • the second sensor corresponding to a lower resource level can primarily be used to correct and/or overwrite the counter data with a reference value corresponding to the lower resource level in order to (re)calibrate the counter data and to have an accurate and reliable estimate for the remaining resource in order to reliably and accurately estimate when the dispenser will be empty.
  • control unit is adapted to set the counter data to a predetermined value depending on a signal for detection of the absence of resource received from the sensor for detecting resource usage.
  • the predetermined value corresponds to a reference and/or target value.
  • the predetermined value corresponds to an amount or number of portions of resource remaining at a resource level corresponding to the sensor position.
  • control unit is adapted to send an alarm signal when the counter data exceeds a predetermined value and no signal for detection of the absence of resource has been received from the sensor for detecting resource usage. Further preferably, the control unit is adapted to send an alarm signal when the counter data exceeds and/or falls below a predetermined value when a signal for detection of the absence of resource has been received from the sensor for detecting resource usage.
  • the predetermined value corresponds to a reference and/or target value.
  • this may be an indication that another resource than the one for which the predetermined value had been chosen, is present.
  • the predetermined value can correspond to a value range. In this way, small deviations from the predetermined value will not result in an alarm signal.
  • the emitter and/or the receiver of radiation are arranged on a support structure and/or are covered with layer comprising or consisting of material permeable to radiation.
  • the support structure and or the layer consists of or contains a thermoplastic polymer, in particular polycarbonate.

  • the sensor can remain deactivated, for example, after the detection of the absence of resource and/or until a predetermined number of portions has been dispensed.
  • the sensor can be manually activated when the resource container or resource supply is exchanged. It can also be preferred that the sensor is operated with a longer pulse interval after having detected the absence of resource. Then, as soon as the sensor detects the presence of a resource (corresponding to the exchange of the resource container or resource supply), it can be preferred that the sensor is operated with a shorter pulse interval.
  • the senor can be deactivated or operated with a longer pulse interval in the beginning of a detection cycle until a predetermined number of portions has been dispensed.
  • the predetermined number of portions is lower than the target number of portions corresponding to the amount of resource between the full level and the level corresponding to the sensor position.

  • the emitter and the receiver are produced on a single support element, possibly together with the control unit, wherein the single support element is then separated into two or more support elements during manufacture.
  • the support element is a printed circuit board, which can be separated at one or more predetermined breaking points, for example.
  • the emitter and the receiver of radiation are adapted to emit and detect electromagnetic radiation and/or acoustic radiation, in particular visible light and/or ultrasound. Further, it is preferred that the emitter and the receiver of radiation are adapted to emit and detect pulsed radiation.
