Definitions

  • the present invention relates to a cleaning device and a method for operating a cleaning device.
  • Cleaning devices such as dishwashers typically include a cleaning space for receiving items to be cleaned and at least one rotatable spray arm disposed in the cleaning space for spraying a cleaning liquid.
  • the cleaning liquid is supplied by means of a circulating pump to the spray arm, which is rotated by the exiting the spray arm cleaning liquid in rotation.
  • the invention has for its object to provide an improved cleaning device and an improved method for operating a cleaning device with which a blocking of a spray arm can be detected and the cleaning result can be improved.
  • the cleaning device of the invention has a cleaning space for receiving items to be cleaned and a arranged in the cleaning room, rotatable or pivotable spray arm for spraying a cleaning liquid,
  • the cleaning device according to the invention further comprises a sensor device for detecting objects in a movement space of the spray arm.
  • the method for operating a cleaning device with a cleaning space for receiving items to be cleaned and a arranged in the cleaning chamber, rotatable or pivotable spray arm for spraying a cleaning liquid according to the invention comprises a step of detecting objects in a movement space of the spray arm.
  • the cleaning device is equipped with a sensor device which can detect objects in a movement space of the spray arm. While only a blockage of the spray arm can be detected with the sensor systems of conventional cleaning devices, the invention can already detect the cause of a possible blockage of the spray arm. There is therefore the possibility of blocking a Sprüharms early, ie even before his occurrence, preferably before the beginning of the cleaning operation to recognize and inform the user of the cleaning device accordingly early. The user is then more likely to be within range of the cleaning device, so that he can perceive and respond to a corresponding error message. As a result, blocking of the spray arm in the cleaning operation can be preferably prevented, and thus the cleaning result can be improved.
  • the cleaning device of the invention is preferably a dishwasher, for example a dishwasher or a dishwasher for cleaning medical devices or laboratory equipment.
  • the cleaning device may have one or more spray arms.
  • each of a plurality of spray arms is assigned its own or a common sensor device.
  • the cleaning device of the invention may preferably comprise, in addition to the sensor device for detecting objects in a movement space of the spray arm, a further sensor device for detecting a rotational movement of the spray arm or a blocking of the rotary movement of the spray arm.
  • the sensor device is designed and arranged such that it can detect objects in the movement space of the spray arm in an idle state of the spray arm.
  • the cleaning device further comprises a control device which is connected to the sensor device and which is configured such that it controls a cleaning operation of the cleaning device in response to a detection signal of the sensor device.
  • a control device which is connected to the sensor device and which is configured such that it controls a cleaning operation of the cleaning device in response to a detection signal of the sensor device.
  • it controls the cleaning operation such that the cleaning operation is started only when the detection result of the sensor device indicates that there are no objects in the movement space of the spray arm.
  • the control device is preferably connected to an operating device of the cleaning device, via which the user an error message can be displayed if the detection result of the sensor device indicates that objects are in the movement space of the spray arm.
  • the invention also relates to a sensor device for a cleaning device of the invention described above.
  • FIG. 1 shows the structure of a cleaning device according to an embodiment of the present invention.
  • FIG. 2 shows different embodiments of a sensor device for a
  • a dishwasher is shown as an example of a cleaning device 10 of the invention.
  • the dishwasher 10 includes a machine housing in which a cleaning chamber 12 is provided.
  • a cleaning chamber 12 In the cleaning room 12 one or more (here two) baskets 14 are arranged, in which the user can place the items to be cleaned.
  • Each of these baskets 14 is associated with a spray arm 16 which is rotatable about an axis of rotation 18 or pivotally in the cleaning chamber 12 (here: in each case below a basket 14) is arranged.
  • the dishwasher 10 has an operating device 20, which is arranged, for example, in a control panel on a front or top side of the dishwasher facing the user.
  • the operating device 20 includes, for example, one or more controls for starting the purging operation, selecting a purging program, selecting a water temperature, and the like, and one or more display elements for displaying operating states of the dishwasher, user-selected parameters, error messages, and the like.
  • the operating device 20 is connected to a control device 22.
  • the control device 22 receives data signals from the operating elements of the operating device 20 and sends control signals to the display elements of the operating device 20.
  • the control device 22 is connected to one or more units (eg circulating pump, heating, etc.) 24 of the dishwasher 10, in order according to the above the control device 20 to control selected rinsing programs and parameters.
  • the controller 22 receives signals from the units 24 of their operating conditions, so that the controller 22 can respond accordingly (e.g., changing the operation of the unit, outputting operating information or error messages, etc.).
  • the dishwasher 10 of the invention further includes one or more sensor devices 26. These sensor devices 26 are for sensing objects (e.g., items) in a travel space of the spray arms 16 which could block rotational movement of the spray arms 16 during the cleaning operation.
  • each sensor arm 16 is assigned a sensor device 16.
  • the sensor devices 26 are wired or wirelessly connected to the controller 22 to be activated thereby and to send the detection results as measurement signals.
  • the sensor devices 26 are first activated by the controller 22 before the start of the wash program.
  • the activated sensor devices 26 detect whether or not there are objects (eg, long cutlery, tall vessels, stems of cookware, etc.) in the movement spaces of the respective spray arms 16. Only when the detection results of all sensor devices 26 of the dishwasher 10 indicate that there are no objects in the movement space of the spray arms 16, the controller 22 controls the units 24 to start the wash program.
  • control device 22 prevents the beginning of the wash program and instead outputs an error message (acoustically and / or optically) via the operating device 20.
  • the user is at this time shortly after pressing the control device 20 usually still in the immediate vicinity of the dishwasher 10 so that he can perceive the error message.
  • the user can therefore still respond to an imminent blockage of the spray arms 16 in the cleaning room 12 by checking the items to be washed in the baskets 14 and possibly repositioned.
  • the risk of blocking the spray arms 16 during the cleaning operation can be reduced, so that the cleaning result can be improved.
  • An additional rinsing process can thus be avoided, whereby a consumption of resources (energy, water, detergent, etc.) can be reduced.
  • a sensor device 26 may have one or more sensors. These sensors can be arranged at different positions in the cleaning space 12 of the dishwasher 10 and / or can cover different detection areas. In addition, the sensors can be based on different detection methods (eg ultrasound, light, radar, etc.).
  • FIG. 2 shows various possible arrangements for the sensors 28 of a sensor device 26. For example, as shown in FIG. 2A, a plurality of sensors 28 may be disposed substantially in the plane of movement of the spray arm 16 along a wall of the cleaning space 12. For example, the detection spaces of the sensors 28 are substantially parallel to one another and cover the entire width of the cleaning space 2.
  • a sensor or sensor array 28 may also be disposed in a corner between two walls of the cleaning space 12 (see FIG. 2B) or in a center of a wall of the cleaning space (see FIG. 2C) and a sector-type detection space in the plane of movement of the spray arm 16 cover.
  • FIGS. 2A to D can also be combined with one another in any desired manner.
  • the sensors 28 shown in FIGS. 2A-D may each include transmit and receive functions or may only represent transmitters that interact with additional receivers (not shown).
