An internal unit of a washing machine or spin-dryer normally includes a washing container, which has a laundry drum mounted in the container such that it can rotate, and an electric motor for driving the laundry drum via a reduction gear, a transmission, or direct drive. The internal unit is suspended in a machine housing such that it can vibrate and constitutes an overall system which can vibrate in a damped manner and which is subject to unbalance-dependent resonance phenomena in specific regions of the rotational speed of the laundry drum. The causes of these resonance phenomena are vibratory movements due to momentary unbalances in the load in the laundry drum. To reduce these unbalance-dependent resonance phenomena, the internal unit is provided with a vibration sensor which is rigidly or substantially rigidly coupled to the internal unit.
An internal unit for a laundry treatment machine, the internal unit being suspended such that it can vibrate in the laundry treatment machine, the internal unit comprising:
A method for controlling a laundry treatment machine having at least one sensor measuring vibratory movements of an internal unit of the laundry treatment machine, the internal unit containing a laundry drum and an electric motor for driving the laundry drum, the at least one sensor being an electronic sensor rigidly or substantially rigidly coupled to the internal unit, which comprises the steps of:
A method of using an electronic sensor in an internal unit for a laundry treatment machine, the internal unit being suspended such that it can vibrate in the laundry treatment machine, the internal unit having a laundry drum and an electric motor for driving the laundry drum, which comprises the steps of:
