Definitions

  • the present invention relates to a washing machine.
  • the laundry when loaded inside the drum of a front-loading washing machine, the laundry accumulates on the bottom of the cylindrical lateral wall of the drum, and is subsequently distributed dynamically and randomly over the whole lateral wall of the drum during all the stages in the wash cycle in which the drum rotates about its longitudinal axis, with the exception of the spin stage, in which the fast rotation speed of the drum stabilizes and freezes distribution of the laundry on the lateral wall.
  • the laundry is obviously not distributed perfectly evenly over the whole lateral wall of the drum, so that, as the drum rotates, and particularly at the spin stage, mechanical vibration is produced which increases as a function of the extent to which the laundry is distributed unevenly, instant by instant, inside the drum.
  • the entire wash assembly of the machine is normally suspended in floating manner from the machine casing by a system of springs and shock-absorbers designed to absorb at least part of the vibration.
  • BE 1012788A6 discloses a washing machine comprising a drum provided with at least three tanks which may be filled with water before the rinsing phase, and which may be emptied during the rotation of the drum, so as to balance the imbalance of the drum due to the presence of the laundry.
  • washing machine as claimed in Claim 1 and preferably, though not necessarily, in any one of the dependent Claims.
  • Number 1 in Figure 1 indicates as a whole a washing machine, which is particularly advantageous for home use, and substantially comprises a casing 2 resting on the floor; a preferably, though not necessarily, cylindrical wash tub 3 suspended in floating manner inside casing 2 by means of a number of coil springs 4 (only one shown in Figure 1 ) preferably, though not necessarily, combined with one or more known shock-absorbers 5; a rotary drum 6 housed, to rotate axially about its longitudinal axis A, inside wash tub 3; and a drive unit 7 connected mechanically to drum 6 to rotate it about its longitudinal axis A inside wash tub 3.
  • Wash tub 3, drum 6, and the other component parts of washing machine 1 suspended from casing 2 by coil springs 4 form the wash assembly of the washing machine.
  • washing machine 1 also comprises a laundry weight detecting device 8 for determining the weight of the laundry currently inside drum 6, and for communicating the weight value to the electronic central control unit 9 of washing machine 1, which in turn optimizes the wash cycle parameters in known manner as a function of the actual weight of the laundry inside drum 6.
  • laundry weight detecting device 8 determines the instantaneous total weight of the current contents of drum 6, i.e. the total weight m tot of the current amount of laundry inside drum 6. Unlike known solutions, laundry weight detecting device 8 also extrapolates, from the total weight m tot of the current amount of laundry inside drum 6, the balanced component and the unbalanced component of the weight of the laundry inside drum 6.
  • the balanced component represents the weight of the amount of laundry distributed evenly inside drum 6, and the unbalanced component represents the weight of the amount of laundry distributed unevenly, and therefore in unbalanced manner, inside drum 6.
  • the dynamic behaviour of the laundry distributed randomly on the lateral wall of drum 6 rotating about longitudinal axis A may be represented schematically as a combination of the dynamic behaviour of a balanced mass m 1 and an unbalanced mass m 2 , both located inside the rotating drum 6.
  • the balanced mass m 1 is distributed evenly on the lateral wall of drum 6, and, being perfectly balanced, causes no mechanical vibration; whereas, the unbalanced mass m 2 is concentrated at one point on the lateral wall of drum 6, and causes vibration which is absorbed by coil springs 4 and shock-absorbers 5 supporting the wash assembly.
  • the weight m 1 of the amount of laundry distributed evenly inside drum 6 obviously corresponds to the balanced mass m 1 of the kinematic model, and the weight m 2 of the amount of laundry distributed unevenly inside drum 6 corresponds to the unbalanced mass m 2 of the kinematic model.
  • the weight of balanced mass m 1 , the weight of unbalanced mass m 2 , and the position of unbalanced mass m 2 on the lateral wall of drum 6 obviously vary from one instant to the next as a function of the current distribution of the laundry inside drum 6, and are stabilized or frozen when drum 6 reaches a rotation speed capable of immobilizing the laundry on the lateral wall of drum 6.
  • laundry weight detecting device 8 is therefore able to determine the total weight m tot of the current contents of drum 6, i.e. the total weight m tot of the current amount of laundry inside drum 6, and also to determine instant by instant the weight of balanced mass m 1 and the weight and position of unbalanced mass m 2 of the equivalent laundry kinematic model, and to transmit these parameters to electronic central control unit 9 of machine 1.
  • laundry weight detecting device 8 determines instant by instant the total weight of the wash assembly weighing on coil springs 4, and then determines the weight of balanced mass m 1 and the weight and position of unbalanced mass m 2 corresponding to the kinematic laundry model, by extrapolating them from the time pattern, within a predetermined reference time interval and as drum 6 rotates, of the weight weighing on coil springs 4 supporting the wash assembly.
  • Laundry weight detecting device 8 obviously also determines the total weight m tot of the actual amount of laundry inside drum 6 by summing the weight of balanced mass m 1 and the weight of unbalanced mass m 2 .
  • laundry weight detecting device 8 indirectly determines the instantaneous total weight of the wash assembly weighing on coil springs 4, by determining the instantaneous length l of at least one of coil springs 4 supporting the wash assembly inside casing 2.
  • laundry weight detecting device 8 statistically processes the time pattern l(t) of length l of coil spring 4 within a predetermined time interval ⁇ T, in which drum 6 rotates at a predetermined rotation speed ⁇ 0 high enough to freeze distribution of the laundry on the lateral wall of drum 6, so as to determine the mean value l m of length l of the reference coil spring 4 within the time interval ⁇ T in which drum 6 rotates at freezing rotation speed ⁇ 0 ; and then calculates the total weight m tot of the current amount of laundry inside drum 6 on the basis of the mean value l m of length l of reference coil spring 4, and taking into account the weight of drum 6 and the way the total weight of the wash assembly of machine 1 is distributed between coil springs 4 supporting wash tub 3.
  • Laundry weight detecting device 8 also statistically processes the time pattern l(t) of length l of coil spring 4 within time interval ⁇ T to determine the deviation ⁇ l in the time pattern l(t) of length l of reference coil spring 4, and then extrapolates from deviation ⁇ l the actual weight of the mass of laundry theoretically concentrated in one point on the lateral wall of drum 6, i.e. the weight of unbalanced mass m 2 of the kinematic model.
  • laundry weight detecting device 8 calculates the weight of the mass of laundry theoretically distributed evenly over the whole lateral wall of drum 6, i.e. the weight of balanced mass m 1 of the kinematic model, as the difference between the total weight m tot of the laundry inside drum 6, and the weight of unbalanced mass m 2 of the kinematic model.
  • washing machine 1 also comprises a position sensor 10 for determining a predetermined reference angular position of drum 6 inside wash tub 3, and laundry weight detecting device 8 first compares the signals from position sensor 10 with the time pattern l(t) of length l of reference coil spring 4 within time interval ⁇ T to determine the time difference between the peaks in the time pattern l(t) of length l of coil spring 4 and the signals from position sensor 10, and then calculates the angular position of the point on the lateral wall of drum 6 at which unbalanced mass m 2 of the kinematic model is theoretically concentrated, on the basis of the freezing rotation speed ⁇ 0 of drum 6 and the above time difference.
  • washing machine 1 also comprises a drum balancing device 11, which, under control of electronic central control unit 9, dynamically balances the laundry inside drum 6 by temporarily forming inside drum 6 a number of counterweights for compensating the effects of unbalanced mass m 2 of the kinematic model equivalent to the temporary distribution of the laundry on the lateral wall of drum 6.
  • drum balancing device 11 temporarily forms inside drum 6 a number of counterweights rotating with drum 6, and the weight and position of which are determined so that the resulting dynamic behaviour can be represented schematically by a kinematic model comprising a balanced mass m 3 and an unbalanced mass m 4 , and in which the weight of unbalanced mass m 4 substantially equals the weight of unbalanced mass m 2 of the kinematic laundry model. Moreover, unbalanced mass m 4 and unbalanced mass m 2 of the kinematic laundry model are located at diametrically opposite points on the lateral wall of drum 6.
  • drum balancing device 11 comprises a number of (at least three) wash water storage tanks 12 angularly spaced - preferably, though not necessarily, equally spaced - on the lateral wall of drum 6, and which are filled with a variable quantity of wash water; and a number of regulating valves 13 for controlling wash water flow to and from individual tanks 12.
  • Drum balancing device 11 also comprises a valve control assembly 14, which, under control of electronic central control unit 9, opens regulating valves 13 on drum 6 independently of one another to adjust the amount of water inside individual tanks 12.
  • electronic central control unit 9 of machine 1 calculates the amount of water required inside each tank 12 to obtain an unbalanced mass m 4 of the same weight as unbalanced mass m 2 of the kinematic laundry model, and positioned diametrically opposite unbalanced mass m 2 on drum 6, i.e. specularly with respect to the axis of rotation of drum 6, and then operates valve control assembly 14 to achieve the calculated optimum distribution of water inside tanks 12.
  • drum balancing device 11 comprises three wash water storage tanks 12 defined by three vessels or cavities 12 formed directly, 120° apart, on the lateral wall of drum 6; and each tank or vessel 12 is connected to wash tub 3 by a controlled-release drain valve 13 fitted inside the lateral wall of drum 6 to connect the inside of vessel 12 to the gap between wash tub 3 and drum 6.
  • Controlled-release drain valve 13 is designed to selectively and alternatively assume a first operating configuration, in which it isolates tank 12 from wash tub 3 to prevent water flow to or from tank 12, and a second operating configuration, in which it connects tank 12 to wash tub 3 to allow water flow to or from tank 12, depending on the position of tank 12 inside wash tub 3.
  • controlled-release drain valve 13 comprises a movable shutter 13a for controlling water flow from wash tub 3 to tank 12, and vice versa, by moving, inside the body of valve 13 and in a direction preferably, though not necessarily, perpendicular to the lateral wall of drum 6, between a closed position cutting off water flow through valve 13, and a fully-open position allowing free water flow through valve 13; and a coil spring 13b, or other elastic member, inserted inside the body of valve 13 to hold movable shutter 13a in the closed position.
  • Valve control assembly 14 is designed to selectively open and close regulating valves 13 on command as the corresponding wash water storage tanks 12 travel through the bottom portion 3a of wash tub 3, where the wash water normally accumulates during normal operation of machine 1, or through the top portion of wash tub 3.
  • valve control assembly 14 substantially comprises two coils 15 and 16 of electrically conducting material, which are fixed to the body of wash tub 3, one at the bottom of bottom portion 3a of wash tub 3, and the other at the top of top portion 3b of wash tub 3; and an electric power unit 17 for circulating electric current through coils 15 and 16 independently of each other and under direct control of electronic central control unit 9.
  • coil 16 occupies a larger portion of the wall of wash tub 3 than coil 15 underneath.
  • Each coil 15, 16 is oriented to generate, when supplied with electric current, a magnetic field which interacts with the magnetic field of the permanent magnet in movable shutter 13a of the valve 13 currently facing coil 15, 16, and moves movable shutter 13a temporarily into the fully-open position in opposition to respective coil spring 13b. Moving movable shutter 13a into the fully-open position obviously allows water flow to or from tank 12, depending on the rotation speed of drum 6 about longitudinal axis A and the position of coil 15, 16 on wash tub 3.
  • washing machine 1 Operation of washing machine 1 will now be described, assuming wash tub 3 is filled with water to a predetermined level W high enough to completely immerse tanks 12 moving past coil 15, and that the selected wash cycle has finished the various stages preceding the spin stage.
  • electronic central control unit 9 of washing machine 1 operates drive unit 7 to move all of tanks 12 of drum balancing device 11 successively to the bottom portion 3a of wash tub 3 and into position facing coil 15, and simultaneously activates electric power unit 17 to power coil 15 and open the regulating valve 13 of the tank 12 stopped directly over coil 15.
  • opening valve 13 allows wash water to flow freely into and completely fill tank 12.
  • electronic central control unit 9 operates drive unit 7 to rotate drum 6 at freezing rotation speed ⁇ 0 and so freeze distribution of the laundry on the lateral wall of drum 6.
  • electronic central control unit 9 activates laundry weight detecting device 8, which, by analysing the time pattern l(t) of length l of reference coil spring 4, determines the weights of balanced mass m 1 and unbalanced mass m 2 corresponding to the actual distribution of the laundry inside drum 6, and the angular position on the lateral wall of drum 6 of the point at which the whole unbalanced mass m 2 of the kinematic laundry model is assumed to be concentrated.
  • laundry weight detecting device 8 calculates the weights of the balanced mass m 1 ' and unbalanced mass m 2 ' corresponding to the kinematic model of drum 6 rotating at rotation speed ⁇ 0 together with the laundry and the masses of water stored in tanks 12.
  • drum 6 is defined at the design stage, and drum 6 is balanced at the production stage and so forms no part of the unbalanced mass of the kinematic model of drum 6.
  • central control unit 9 calculates the amount of wash water required in each tank 12 of drum balancing device 11 to compensate the unbalanced mass m 2 ' formed by the laundry and the water in tanks 12 (as stated, drum 6 is balanced at the production stage and forms no part of the unbalanced mass of the kinematic model of drum 6), and then operates electric power unit 17 to power coil 16 synchronously with the passage of individual tanks 12 past coil 16, and so selectively open regulating valves 13 to drain surplus water from individual tanks 12.
  • laundry weight detecting device 8 calculates the weights of the balanced mass m 1 ' and unbalanced mass m 2 ' corresponding to the kinematic model of a mass system rotating at rotation speed ⁇ 0 , wherein the mass system comprises drum 6 as it is, all the water inside drum 6 (both inside and outside of tanks 12), and all laundry inside drum 6.
  • electronic central control unit 9 calculates the amount of wash water required in each tank 12 of the drum balancing device 11 to compensate the unbalanced mass m 2 ' formed by drum 6, the laundry and the water inside drum 6(tanks 12 included); and then operates electric power unit 17 to power coil 16 synchronously with the passage of individual tanks 12 past coil 16, and so selectively open regulating valves 13 to drain surplus water from individual tanks 12.
  • the amount of wash water to be drained from each tank 12 of drum balancing device 11 is calculated on the basis of the mathematical model, which, as a function of the amount of water inside individual tanks 12, provides for determining the weight of balanced mass m 3 and the weight and position of unbalanced mass m 4 of the kinematic model schematically representing the dynamic behaviour of the counterweights defined by the masses of water inside tanks 12, assuming tanks 12 are all originally filled completely with wash water, and therefore perfectly balanced, and so form no part of unbalanced mass m 2 '.
  • electronic central control unit 9 assumes the parameters of unbalanced mass m 2 ' from laundry weight detecting device 8 depend solely on the uneven distribution of the laundry on the lateral wall of drum 6 (i.e. unbalanced mass m 2 ' coincides with unbalanced mass m 2 ), and regulates the amount of water inside tanks 12 so that the unbalanced mass m 4 produced by optimum distribution of the water in tanks 12 of drum balancing device 11 compensates, and eliminates the effects of, the unbalanced mass m 2 ' of the kinematic model of drum 6 (i.e. the unbalanced mass m 2 produced by the laundry distributed randomly inside drum 6).
  • electronic central control unit 9 of washing machine 1 calculates the optimum distribution of water required inside tanks 12 of drum balancing device 11 to obtain an unbalanced mass m 4 of the same weight as unbalanced mass m 2 ' and located diametrically opposite unbalanced mass m 2 ' on drum 6, and then operates regulating valves 13 to drain surplus water from individual tanks 12 to achieve the calculated optimum distribution.
  • electronic central control unit 9 selects the optimum distribution resulting preferably, though not necessarily, in the lightest balanced mass m 3 , and then operates regulating valves 13 to drain surplus water from individual tanks 12 to achieve the selected optimum distribution.
  • electronic central control unit 9 of washing machine 1 may keep track of the changes in individual parameters of the kinematic model of the mass system as water is drained from tanks 12 of drum balancing device 11, and perform an interactive balancing process for reaching the minimum value of the unbalanced component of the overall weight of drum 6 and its load.
  • control unit 9 can provide, at the beginning, a rough distribution of the wash water in tanks 12. Then control unit 9 performs an interactive "fine tuning" of the distribution of the wash water in tanks 12, regulating step by step the water amount inside one or, maybe, two tanks 12 while monitoring the evolution of the unbalanced component value. In other words, during the interactive "fine tuning" control unit 9 repeats many times the calculation of the weights of the balanced mass m 1 ' and unbalanced mass m 2 ' of the kinematic model, and the calculation of the optimum distribution of water required inside tanks 12.
  • electronic central control unit 9 of washing machine 1 discontinues the interactive balancing process in the event of failure to gradually reduce the unbalanced component of the overall weight of drum 6 and its load.
  • Dynamic balancing of drum 6 is terminated when electronic central control unit 9 succeeds in regulating the water inside individual tanks 12 of drum balancing device 11 to achieve the calculated/selected optimum distribution.
  • drum 6 is balanced dynamically, and seeing as the distribution of the laundry inside drum 6 remains unchanged as long as the centripetal force immobilizes the laundry on the lateral wall of drum 6, electronic central control unit 9 of washing machine 1 operates drive unit 7 to increase the rotation speed of drum 6 gradually to the maximum speed of the spin cycle, with no mechanical vibration being caused by rotation of drum 6.
  • the wash assembly suspension system i.e. coil springs 4 and shock-absorbers 5, can be designed to simply absorb minor mechanical vibration produced by low-speed rotation of drum 6.
  • drain valves 13 may be conventional controlled-open-close solenoid valves.
  • valve control assembly 14 may comprise a central control unit fixed to the casing; and wiring for electrically powering the solenoid valves on the lateral wall of drum 6.
  • the solenoid valve central control unit may obviously be integrated in electronic central control unit 9 of washing machine 1.
  • valve control assembly 14 comprises only bottom coil 15 which, in moving the movable shutter 13a into the fully-open position, can selectively fill up tanks 12 with water, or drain surplus water from tanks 12. In fact, when drum 6 reaches freezing rotation speed ⁇ 0 , the centrifugal force is high enough to push the water out of each tank 12 even if said tank 12 faces the bottom portion 3a of wash tub 3 and is submerged in the wash water.
  • the washing machine also comprises a second position sensor 10 for determining a predetermined angular position of the drum 6, and a second electronic control unit 9 which compares the time pattern l(t) of the length l of the coil spring 4 within said reference time interval ⁇ T with the signals from said second position sensor 10.
