Household appliance for treating soft goods with displacement sensor

Abstract

The present description relates to a household appliance for treating soft goods, in particular a laundry washing or washing / drying machine of the electronically controlled type fitted with an electronic control system (17). The household appliance comprises an oscillating assembly connected to the frame by means of a suspension system comprising at least one damper (1). The damper (1) comprises two elements (3, 4) adapted to move reciprocally, at least one magnetic element, preferably a permanent magnet (9), and an electronic module (6) provided with at least one magnetic sensor, preferably a Hall element (12). The magnetic element (9) and the magnetic sensor (12) are housed in the damper (1) so as to detect the reciprocal motion of the two elements (3, 4). The electronic module (6) also comprises a microcontroller (16) connected to the magnetic sensor (12) and adapted to generate at least one piece of information, in particular at least one piece of information being representative of the value of the displacement of the oscillating assembly with respect to the frame, and to send said information to the electronic control system (17) over a digital communication line.

Description

technical field [0001] The invention relates to a household appliance for treating textiles, preferably a laundry washing or washing / drying machine, according to the preamble of claim 1 . Background technique [0002] For household appliances currently available on the market, several types are suitable for measuring the relative displacement of a vibrating assembly (or basin assembly if the household appliance is a laundry washing or washing / drying machine) with respect to the appliance frame to detect, for example, Sensing means are available for the quality or weight of the laundry and / or the value of any load imbalance during operation of the appliance. The sensing device is often built into one of the commonly used mechanical parts of the household appliance. [0003] If the household appliance is a laundry washing or washing / drying machine, the sensing means for measuring the relative displacement of the vibrating assembly relative to the appliance frame may suitably ...

Problems solved by technology

[0007] Also, the measurement system described in patent DE4319614C1 does not take into account the influence of possible external disturbances on the displacement measurement, such as temperature changes in the position of the Hall elements or elasticity and / or Damping change
