Definitions

  • US 5,280,660 describes a method for balancing a washing machine whose drum rotates about a horizontal axis, wherein the washing machine is equipped with at least three water chambers distributed peripherally inside the drum, which chambers selectively receive a preset amount of water from their respective solenoid valves depending upon the result of the vibration measured by a vibration sensor and the drum unbalance position measured by means of a proximity sensor, the signals from both sensors being combined to select the water supply that will compensate for the unbalance, and a motor that accelerates the drum to maximum spinning speed during the compensation process.
  • US 4,517,695 describes a method for balancing a washing machine whose drum rotates about a horizontal axis, wherein the drive motor is connected to a rotation speed control device that controls drum acceleration from an initial spinning speed to a final speed, depending upon the force exerted by the unbalance of the clothing and the comparison thereof with a preset value calculated for the final spinning speed.
  • drum rotation is accelerated from a low initial value to a high final maximum spinning value, in spurts by means of various abrupt speed increases, and maintaining constant velocity in each spurt, in intervals whose length depends upon the result of the measurement of vibration at each constant speed value.
  • a preset quantity of water is placed in the selected compensation chamber, and this action is repeated until the measured vibration value falls below a certain reference value.
  • the acceleration time that transpires until the maximum speed for carrying out the compensation method is reached is excessive, because the water is added to the compensation chambers in ever-equal given doses, and because the drum undergoes successive accelerations after acceleration-free intervals.
  • smooth rotation is achieved without exceeding an admissible washing machine vibration value by means of drum acceleration at a gradual rate until reaching a maximum speed, while the unbalance of the clothes is compensated for in a shorter total process time.
  • the drum drive motor is controlled through a voltage/frequency speed variator governed by the washing machine's electronic controller to regulate the rate of drum acceleration as a function of the result of the vibration measurement and its comparison with a preset reference value.
  • the vibration reference value for comparison with the real value is changing throughout the range of spinning speeds and is reduced as the drum accelerates to maintain the unbalanced mass of the drum always below a constant value, inasmuch as vibration increases at a square rate with the drum speed.
  • the speed variator also allows the torque of the drum drive motor to be raised at a speed as low as 10 r/min, to effect full water chamber emptying before beginning a new balancing process.
  • FIG. 2 is a wiring diagram of the sensor used to measure vibration.
  • FIG. 3 is a diagram of the measurement of the vibration generated by the drum unbalance combined with the measurement of the unbalance position.
  • FIG. 4 is a diagram of the different drum accelerations depending upon the unbalance, in a first embodiment of the invention.
  • FIG. 5 is the diagram of the steps included in the first preferred embodiment of the balancing method.
  • FIG. 6 is a diagram of the different drum accelerations depending upon the unbalance, in a second embodiment of the balancing method.
  • FIG. 7 is a diagram of the magnitude of vibration during the course of drum acceleration according to the diagram in figure 6.
  • FIG. 8 is the diagram of the steps included in a second preferred embodiment of the balancing method.
  • the washing machine 1 for executing the method according to the invention is comprised of a tub 2 fixed to the washing machine structure, the drum 3 rotating about a horizontal drive axis 3 a through whose internal periphery are distributed three water chambers 4 a ,4 b ,4 c , a housing 2 a holding the bearings of the axis 3 a which is fixed to the rear of the tub 2, the induction motor 5 for driving the drum 3, the washing machine's electronic controller 6, the voltage-frequency converter speed variator 7, the device 8,9 for detecting vibration and position, and the solenoid valves 10 a ,10 b ,10 c activated individually by the controller 6 to compensate for the unbalance by means of selectively filling the chambers 4 a ,4 b ,4 c by means of water streams according to the arrows 13 in figure 1.
  • the drum drive motor 5 shown in figure 1 has two windings 14,15 powered separately to achieve two ranges of drum rotation speed N, the low 35-to-55 r/min speed for clothes washing and the high spinning speed between 200 and 900 r/min, these latter two speeds being referenced respectively as Nini and Nmax. Both windings of the motor 5 are powered through the speed variator 7, the low-speed winding 14 to reduce the speed N to a very low value such as 10 r/min when the chambers 4 a ,4 b ,4 c are to be emptied, and the winding 15 to bring the speed N up gradually to spinning speed during the unbalance compensation process.
  • the unbalance detection device 8,9 includes a vibration magnitude sensor 8, shown in figure 2, and an unbalance position sensor 9 shown in figure 3, which rotates of a piece with the drum axis 3 a .
  • the vibration sensor 8 used for the execution of the compensation method is preferably constructed using a strain gauge 8 a and an associated circuit 8 b for filtering, amplifying and processing the output signal.
  • the gauge 8 a is fixed through a substrate to the bearing-holding housing 2 a where it is easily accessible and in a place to which all radial drum vibration is transmitted.
  • the circuit 8 b faithfully reproduces the oscillation of the vibration through its signal 11 of electrical voltage V oscillating between two alternating peak values Vc which is almost a sine function, shown in figure 3, and the numerical result of the measurement is the value lying between the negative and positive peak values Vc.
  • the sensor 9 sensing the unbalance position in relation to the water chambers 4 used preferably for the execution of the method is an optic sensor where the photoelectric transmitter not shown in the figures is associated with a rotating disk fixed to the axis 3 a and perforated with a number of orifices 9 b distributed uniformly over its periphery indicating the angle rotated by the drum.
  • the position sensor 9 could also be a magnetic proximity or Hall effect sensor.
  • One of the perforations in the disk in sensor 9 is a long groove 9 a whose position relative to one of the chambers 4 is recorded in the controller 6, serving as a zero reference of the angle rotated by the drum 3.
  • the photoelectric transmitter provides an electrical signal 12 associated with the position of the groove 9 a , and the controller 6 combines the two electrical signals 11 and 12 to measure the phase angle p hi, as shown in figure 3, between the said groove 9 a and the peak value Vc of the vibration signal 11, to select one or two of the three chambers 4 a ,4 b ,4 c , diametrically opposite the location of the mass causing the unbalance.
  • Figure 4 depicts the acceleration of the drum 3 by means of the variator 7 in a first preferred embodiment of the method 20 for balancing the drum 3 according to the stage diagram in figure 5.
  • the acceleration of the drum 3 takes place smoothly, from the initial spinning speed Nini to the maximum speed Nmax, and gradually by means of tiny successive delta N increments, for example increments of 50 r/min or less at a time, yielding different rates of acceleration N1 to N4 as a function of the initial unbalanced mass.
  • the different drum accelerations N1 to N4 are the effect of the different times t transpired for the flow 13 to supply the necessary amount of water to the selected chamber 10.
  • Vibration magnitude is measured between the two opposing values Vc of the signal from sensor 8 shown in figure 3.
  • the first preferred embodiment 20 of the balancing method includes prior steps 21 to 24, the balance compensating sequence of steps 25 to 31, and final steps 32 and 33, which include:
  • step 31 which increases occur continuously one after another, since the stream of water 13 flows uninterruptedly until the maximum spinning speed Nmax is reached.
  • the second embodiment 40 of the balancing method according to the diagram in figure 8 includes the same prior steps 41 to 44 as the first embodiment, plus the previous record of different acceleration rates N5 to N9, shown in figure 6, in the controller 6, since the speed increase is continued at one of the said rates N1 to N9, an acceleration rate N8 being chosen after the measurement of the vibration Vc at the initial speed Nini.
  • Steps 45 to 50 included in the repeated sequence of operations are the same as in the first embodiment 20, except that the speed increase delta N, step 47, is inserted between measurement 45 and comparison 49 of the measured value Vc with the threshold value Vum, the water supply 13 in this second embodiment being interrupted, step 51, according to the result of the comparison in step 49.
  • the vibration measurement Vc is compared to the threshold value Vum, step 49, and the result thus found conditions the activation and deactivation of the selected solenoid valve 10, since inasmuch as the acceleration N8 is uninterrupted, when the measurement Vc is less than the value Vum, the valve is deactivated, step 51, and the selected chamber 4 is prevented from overloading, which could cause an unbalance in the position of the selected chamber 4 greater than the unbalance of the initial mass of clothes in the drum 3 in the opposite position.
  • the measurement Vc oscillates with the course of time around the threshold value Vum, the solenoid valve 10 being connected when Vc is greater than Vum, step 50, while the acceleration N8 is continuous.
