Definitions

  • the present invention relates to a movement monitoring arrangement for monitoring a movement of a laundry drum of a laundry treatment device and also to a laundry treatment device with such a movement monitoring arrangement.
  • a tub In laundry treatment devices such as washing machines and tumble dryers, a tub is usually mounted so that it can oscillate via springs and vibration dampers in the machine housing and a laundry drum is rotatably mounted inside the tub.
  • a laundry drum In order to achieve a good flow of the planned laundry treatment process and to avoid operational failures or operational problems, it is important to monitor the operating status of the laundry treatment device. For this purpose, an imbalance of the laundry drum is usually also detected, which can occur particularly with large load masses and at high speeds of the laundry drum, in order to adapt the operation of the drum so that critical operating behavior of the laundry drum can be avoided.
  • the motion monitoring arrangement according to the invention for monitoring a movement of a laundry drum of a laundry treatment device has: at least two motion sensors, each of which is designed for multi-axis motion detection; at least one mounting element for rigidly mounting components of the motion monitoring arrangement on the laundry drum or another movable component (e.g. tub), the movement of which is coupled to the movement of the laundry drum, with fixed positioning of the at least two motion sensors; and an operating device for controlling the at least two motion sensors and evaluating the measurement signals of the at least two motion sensors, which is connected to the at least two motion sensors.
  • the motion monitoring arrangement further has a communication element connected to the operating device (e.g.
  • the operating device is configured to adapt the evaluation of the measurement signals from the at least two motion sensors to the mounting position data transmitted by the communication element.
  • the machine control has received appropriate information about this mounting position data, for example from the manufacturer or installer of the laundry treatment device.
  • this motion monitoring arrangement does not require any adjustment or modification of the other device components.
  • the configuration of the machine control and the motor electronics of the laundry treatment device does not need to be modified, or only insignificantly, because they do not require any specially generated measurement signals have to evaluate, but receive evaluation results of the measurement signals directly from the motion monitoring arrangement according to the invention. This advantageously results in simpler and more cost-effective structures and production of the laundry treatment devices.
  • the motion monitoring arrangement of the invention can preferably be used for the overall operational monitoring of the laundry treatment device. This particularly includes unbalance detection.
  • the motion sensors with multi-axis motion detection are preferably 3D sensors or at least 2D sensors.
  • the motion monitoring arrangement in particular the motion sensors, can generally be installed at any position on the laundry drum or, for example, the tub.
  • the rigid mounting of the motion monitoring arrangement with fixed positioning of the motion sensors ensures that the motion sensors remain essentially stationary and positioned with a substantially stable orientation even during operation of the laundry treatment device and that the relative positioning between the motion sensors remains essentially unchanged even during operation of the laundry treatment device remains. This can ensure that the movement of the motion sensors corresponds to the movement of the laundry drum or tub and so that their measurement signals directly represent the movements of the laundry drum or tub and the evaluation of the measurement signals can be reliably guaranteed by the operating device.
  • the at least two motion sensors preferably include at least one acceleration sensor and/or at least one gyroscope.
  • the motion monitoring arrangement includes a 3D acceleration sensor and a 3D gyroscope.
  • the motion monitoring arrangement can also contain, for example, two or more multi-axis acceleration sensors and/or two or more multi-axis gyroscopes.
  • the at least two motion sensors can be mounted on a common support plate, which can be mounted on the laundry drum or the other movable component via the at least one mounting element.
  • the operating device can either (i) also be mounted on the common support plate or (ii) be mounted on a separate support plate, which has at least one mounting element (iia) on the laundry drum or the other movable component or (iib) separately from the laundry drum and the other movable component can be mounted.
  • the at least two motion sensors can each be mounted individually on an individual support plate, which can each be mounted on the laundry drum or the other movable component via at least one mounting element of the at least one mounting element.
  • the operating device can optionally (i) be mounted on one of the individual support plates for one of the motion sensors or (ii) be mounted on a separate support plate which is attached to the laundry drum or the other movable component via at least one mounting element (iia) or ( iib) can be mounted separately from the laundry drum and the other movable component.
  • the carrier plates mentioned in the aforementioned embodiments can optionally also be part of a housing of the motion monitoring arrangement or can be designed in the form of a circuit board.
  • the two aforementioned configurations can also be combined, i.e. at least one common carrier plate can be provided for at least two motion sensors and at least one further carrier plate for a single motion sensor.
  • the operating device is preferably configured to determine the evaluation results based on the timing of the measurement signals from all motion sensors across all measurement axes.
  • the motion monitoring arrangement further has at least one energy supply element for generating and/or receiving electrical energy for the operation of the motion monitoring arrangement, in particular for the operation of its operating device, its motion sensors and its communication element.
  • the energy supply element can also be designed to store the generated or received electrical energy.
  • the electrical energy from the energy supply element can be received, for example, via a connecting line or wirelessly from the machine control of the laundry treatment device.
  • the movement monitoring arrangement described above can advantageously be used in a laundry treatment device which has a machine housing, a tub which is suspended in the machine housing so that it can oscillate, a laundry drum which is rotatably mounted in the tub about an axis of rotation, an electric motor for rotating the laundry drum, motor electronics for operational control of the electric motor, and a machine control connected to the motor electronics (eg integrated or coupled) for controlling the operation of the laundry treatment device.
  • the at least two motion sensors of the motion monitoring arrangement are for monitoring a movement of the laundry drum preferably mounted on the laundry drum or on the tub and the operating device of the movement monitoring arrangement is preferably connected to the machine control and / or the motor electronics.
  • the at least two motion sensors of the motion monitoring arrangement can be mounted, for example, on an axial end face of the laundry drum or tub.
  • the machine control can, for example, be configured to receive information from the manufacturer or installer of the laundry treatment device corresponding to the mounting position data of the at least two motion sensors.
  • the laundry treatment device is, for example, a washing machine, a tumble dryer or a washing machine-dryer combination.
  • the invention is applicable for household appliances as well as for business or industrial purposes.
  • Fig. 1 shows an example of the structure of a washing machine as an example of a laundry treatment device in which the motion monitoring arrangement according to the invention can be used.
  • the washing machine 10 has a machine housing 12 in which a tub (alternatively referred to as a tub) 14 is suspended so that it can oscillate via springs 15 and vibration dampers 16.

  • the motion monitoring arrangement 28 can also be connected to the motor electronics 21 (wirelessly or via cable).
  • the machine control 22 or the motor electronics 21 can then change the operating state of the electric motor 20 and thus the laundry drum 18 if necessary based on the evaluation results received from the motion monitoring arrangement 28 in order to avoid problems or malfunctions in the laundry treatment process. This can be achieved in particular by changing the speed of the laundry drum 18.
  • the machine control can be optional 22 or the engine electronics 21, based on the received evaluation results, also send corresponding information or a warning signal to the control panel 24 if necessary in order to inform the user accordingly.
