Definitions
- the invention relates to a laundry treatment device with a drum and a sensor, in particular for speed control, and a method for its operation.
- the invention relates to a laundry treatment device with a sensor that can be configured as a washing machine, washer-dryer or dryer, and a method for its operation.
- a relatively loud noise can be heard by the movement, in particular by the fall, of wet laundry ("wash clothes") in the rotating drum
- a speed for the drum of about 55 revolutions per minute (rpm, rpm) is set.
- rpm, rpm revolutions per minute
- a similar problem arises in the presence of garments with zippers in the drum. It would therefore be desirable first to dry with a higher speed, which is almost equal to the application speed, and to reduce the speed to the otherwise optimal lower range only at a lower moisture content of the laundry. This could result in a significant reduction of the noise level.
- the US 2003/0037382 A1 relates to a washing machine with a built-noise reduction system, which includes a microphone for audibly detecting at least an imbalance or a pump idle and a control device for changing the washing operation based on the signals received from the microphone.
- the microphone may, in principle, be mounted throughout the washing machine, the microphone generally being an acoustic signal converter that generates an electrical signal in response to a measured sound energy.
- an electric condenser microphone is mentioned.
- the signals received from the microphone can be analyzed by a CPU for imbalance or pump idle, whereupon, for example, the rotational speed of the drum of the washing machine can be adjusted.
- the JP 2007-167175 A describes a washing machine having, in addition to a rotatable drum for receiving laundry, a microphone for receiving acoustic vibration signals generated by the drum and a comparison part for comparing the result obtained by the microphone with reference data for various predetermined washing conditions.
- a drum rotation control part is used to control the washing state of the laundry. Periodic variations in the noise level due to the rotation of the drum are registered and compared with the reference data, whereupon the washing process is controlled accordingly.
- the JP 2007-143630 A describes a washing machine equipped with a vibration sensor which measures vibrations of a specific body, with a transmission noise sensor which measures the noise caused by the vibrations, and a control means for evaluating the information from the vibration sensor and the noise sensor to the rotation of a drive motor to control.
- the object of the present invention was therefore to provide a laundry treatment device and a method for its operation, which allow optimal control of the rotational speed of a drum.
- the invention thus relates to a laundry treatment device with a drum, a motor for driving the drum, a control device and a sensor, wherein the sensor is an acoustic sensor for the measurement of an acoustic signal and the laundry treatment device means for comparing the acoustic signal recorded by the acoustic sensor with a in the control device deposited acoustic reference signal, and wherein the acoustic signal and the acoustic reference signal is each a sonagram.

- a material break can be indicated by means of characteristic noises such as cracking or tearing.
- further noises such as hissing, whistling, hissing, grinding, humming, roaring, banging, knocking, etc. can be detected and suitably evaluated.
- An acoustic sensor could thus also detect leakage noises (leakage of water in the case of a washing machine) or imbalances.
- the acoustic signal is recorded in the form of a sonagram (sometimes called "sonogram").
- the frequency range, sensitivity, signal smoothing, switching threshold and / or output characteristic can be adjusted.

- the acoustic sensor is arranged on a pump of the washing machine or the washer-dryer.
- a control of the pump is possible.
- the noise or sound level during pumping of water is lower than during pumping at idle when there is no water.
- the noise is different when pumping against foam. According to the invention, it can therefore be provided that when measuring an acoustic signal that differs to a predetermined extent from a predetermined average sound level, the pump is stopped or, in the case of a controllable pump, the rotational speed of the pump is changed.

- the display means may indicate the operating condition and / or malfunction of the laundry treating appliance.
- the display device can only serve to visualize the noise generated by the laundry treatment appliance.
- the display means may be one or more parts.
- the invention also relates to a method for operating a laundry treatment device with a drum, a motor for driving the drum, a control device and an acoustic sensor, wherein the acoustic sensor measures an acoustic signal, in particular a sound level, during operation of the laundry treatment device at one or more frequencies, wherein a sonogram is measured as the acoustic signal.
- the measured acoustic signal is preferably compared with a reference signal stored in the control device.
- the acoustic signal measured by the acoustic sensor is preferably compared with a reference signal stored in the control device.
- a rotational speed of the drum is reduced in a pumping step when exceeding a predetermined value ⁇ S v 2 for a difference ⁇ S between the measured acoustic signal and the reference signal stored in the control device for a pumping step, until this predetermined value ⁇ S v 2 reached or fallen below, or the pump is switched off.
