Definitions

  • the invention relates to a non-contact fluid dispenser for dispensing a fluid according to the type specified in the preamble of claim 1.
  • Fluid dispensers that allow a fluid to be dispensed without contact, in particular liquid soap or disinfectant, are sufficiently known from the prior art.
  • a non-contact sensor which is usually located in the vicinity of a dispensing opening
  • a pump is put into operation, which pumps the fluid out of a reservoir and conveys it to the dispensing opening for application to the hands.
  • a fluid dispenser often dispenses at the level of a user's hand, which is normally held, since fluid dispensers are usually mounted on a wall above a washstand well below the user's eye level.
  • Various fluid dispensers are known from the prior art which are surrounded by a housing, e.g. a plastic box, are permanently installed on a wall or are integrated into a surface of a washing device or a sanitary cubicle.
  • WO 2004 054 460 A2 describes a fluid dispenser consisting of a housing with a tunnel on the wall of which a sensor and a spray nozzle for dispensing liquids are arranged, the sensor triggering a pump which is connected to the nozzle and which is connected to a reservoir .
  • the tunnel has a floor sloping towards the rear wall. Under the floor is a drawer for collecting liquid that drains from the tunnel wall.
  • WO 2010 118443 A1 describes a foam soap dispenser which has a housing with a cover. A reservoir of the fluid is interchangeably inserted in the upper area and a working unit is provided in the lower area, which comprises a fluid container, a pump and a foaming device near a dispensing opening.
  • DE 202007 012 093 U1 describes a fluid dispenser intended for wall mounting, which has a two-part housing, comprising a section intended for wall mounting, which is connected via a hinge to a hinged lid.
  • a fluid container for a fluid is arranged in the fluid dispenser, which fluid is pumped out by a pump activated by means of a non-contact sensor.
  • the pump is arranged on an underside of the fluid container in a recess of a motor unit, the motor unit being detachably held on the wall portion of the housing.
  • DE 102010 004 763 A1 describes a contactless fluid dispenser that is particularly suitable for liquid soap or disinfectants.
  • the fluid dispenser has an exchangeable fluid container for the fluid, a delivery device whose pump is set up to discharge the fluid, and a non-contact sensor for triggering a donation process.
  • the rotor, gearbox and drive motor of the conveying device are mounted on a U-shaped carriage that can be moved on two horizontal rods.
  • the fluid dispenser includes a two-part housing.
  • a fluid container is arranged in one housing part and a conveying device is arranged in the other housing part.
  • the fluid dispenser has at least one non-contact sensor, which activates the delivery device for dispensing a fluid from the fluid container.
  • the fluid is dispensed through a dispensing opening located in the area of the sensor.
  • fluid dispensers can be seen in the fact that they are usually tied to a specific shape or size in terms of their design, and are therefore inflexible in a often already specified, very limited installation space with little depth, width and/or height above sinks or washbasins in particular can be used in sanitary cabins, on-board toilets or the like.
  • existing fluid dispensers are usually encased in metal, which increases their installation space requirements and further reduces the design options.
  • the quantities of fluid stored in fluid dispensers are also often small, as a result of which the fluid has to be replaced frequently at short intervals.
  • the object of the invention is to provide a contactless fluid dispenser that can be accommodated in a small space, which has a structurally simple design and allows easy access to its components.
  • a fluid dispenser for the contactless dispensing of a fluid has a housing which is intended in particular for wall arrangement above a washbasin or the like.

  • a working unit is arranged in the second housing part and comprises at least one conveying device and one control device.
  • the control device is operatively connected to the conveying device and has a contactless sensor. When a user's hand approaches the sensor, for example, the control device activates the delivery device to dispense a predetermined quantity of the fluid from the fluid container via the dispensing opening.
  • the fluid dispenser or all electrical and electronic components of the fluid dispenser are supplied with electrical energy, for example by means of a power cable that can be connected to a power grid. However, the fluid dispenser can optionally or additionally be operated by means of a battery.
  • the underside of the second housing part has a base that can be detachably connected to the housing and is designed as a holding device for arranging the working unit.
  • the working unit and the holding device are connected to one another.

  • the bottom or the holding device is detachably connected to the housing, for example via a screw connection.
  • a particular advantage of the present invention is that the entire assembly, ie the holding device together with the working unit, can be removed very easily and quickly from the fluid dispenser in order to access an interior of the fluid dispenser and the granting simplified access to individual components of the working unit outside of the fluid dispenser.
  • the conveyor and the control device can be removed together with the holding device as a complete set. This simplifies the replacement of defective components and reduces waiting times, since, for example, a complete assembly can be replaced with a replacement kit and repairs do not have to be carried out on site.
  • the holding device is designed as a C-shaped bracket in longitudinal section, the base forming a first leg of the bracket and being connected to a second leg running essentially parallel to the base via a connecting section extending in the vertical longitudinal direction of the housing.

  • the sensor can be designed, for example, as a non-contact infrared sensor, which has approximately point detection.
  • the non-contact sensor is activated by moving a part of the body, in particular a hand, into the detection range of the sensor, which can be set to 5 cm to 6 cm, for example.
  • the sensor has an effective range of 20°. Due to the arrangement of the sensor on the bevel, the effective range points at an angle obliquely forwards in the direction of a user, i.e. not vertically downwards, which allows for the rapid detection of an approaching hand contributes.
  • the activated sensor causes the electronics to issue a control command to the delivery device, whereupon this sucks in a defined quantity of fluid, for example between 1.5 g and 3.0 g, from the fluid container and delivers it to the user's hands via the delivery opening.
  • a defined quantity of fluid for example between 1.5 g and 3.0 g

  • the fluid container 34 is formed on an underside with an outlet 68 which has a sealing membrane, not shown here, for sealing off the fluid container 34 .
  • the outlet 68 is connected to a pump 72 of the delivery device 50 via plug-in guide elements 70 .
  • Fluid lines, not shown here, connect the pump 72 on the input side to the plug-in guide elements 70 and on the output side to the dispensing opening 16, which in the present case is designed as a nozzle for dispensing the fluid.

  • the connecting section 78 is designed as a wall running perpendicularly to the base 52, which is screwed to the rear wall 22 of the second housing part 26, as a result of which the second housing part 26 is designed with a double wall in the present case.
  • the control device 48 is arranged on the first leg 78 and the conveyor device 50 is arranged on the second leg 84 . They are spaced apart from one another via the connecting section 82, as a result of which sufficient space is available between the conveying device 48 and the control device 50 for fluid lines, cables and/or batteries or accumulators.
  • the fluid dispenser 10 is preferably connected to a power supply via a power cable, which means that the second housing part 26 can be made even more compact, since there is no space for a battery compartment or the like.
  • the non-contact sensor 62 is arranged in the region of the dispensing opening 16 on the first leg 78 of the holding device 74, which is formed with the bevel 56.
  • the sensor 62 is connected to electronics. In a space-saving manner, the sensor 62 and the electronics are cast together on a circuit board 86 which is arranged on a side of the base 52 facing the second interior space 64 .
  • the sensor 62 sends an impulse to the electronics, which then activates the pump 72 by means of a control command in order to draw in a defined quantity of fluid from the fluid container 34 on the input side and deliver it to the dispensing opening 16 on the output side.
  • the amount of fluid to be dispensed is set over the running time of the pump. For example, the pump runs for a duration of between 20 ms and 30 ms in order to dispense a quantity of fluid between 1.5 g and 3.0 g. A new pulse must be triggered via the sensor 62 in order to issue the fluid again.
