Definitions
- the present invention relates to a method for balancing the load in a laundry washing and/or drying machine.
- a critical element concerning said spinning phases is the risk of having an unbalanced laundry load with the clothes arranged unevenly inside the machine drum, i.e. either concentrated in some areas and not available in other areas, so that during high speed rotation of the drum this unbalanced load condition may in fact cause important machine oscillations or even the risk of a mechanical failure.
- washing machines are provided with special control systems and methods to check whether the laundry load is evenly distributed or balanced inside the drum, before execution of a spinning phase.
- the control system In case of a balanced load, the control system enables execution of the spinning phase, whereas in case of an unbalanced load the control system will remove the unbalance condition and provide for a new distribution phase or at least bring its amount back to acceptable limits for the machine structure.
- the known systems are characterized by the fact that upon detection of a load unbalance, the machine drum stops to start a more or less long and complex new distribution phase for balancing the load.
- a balance phase is carried out letting first the drum rotate in one direction at a given speed (eg. 45 rpm clockwise) and stop for a given time, then repeat drum rotation inversely (eg. 45 rpm anticlockwise) and stop rotation again, and so on, for a certain number of times.
- the method of operation according to the known technology involves rather long operational times dictated by the need of executing a plurality of stops and rotation intervals of the machine drum. Such a problem is further sharpened considering that for some particular types of clothes (as for instance sponge textiles) a load balance is difficult to reach, so that repeated balance attempts are required.
- Fig. 1 a simplified diagram shows the flow of the drum rotation speeds of a laundry washer operating according to the known state of the art in its phases of laundry load distribution, unbalance control and removal.
- the axis of abscissas represents time, whereas the axis of ordinates represents the speed reached by the laundry washer drum during the various phases.
- a first phase indicated by A is foreseen before spin start, which brings the motor and then the drum of the laundry washer to such a speed allowing load satellization, i.e. such as to cause a substantial adhesion of the clothes to the drum walls.
- Said speed, called distribution speed is typically about 90 revs per minute.
- Such a balance measure may be carried out for example during phase B by measuring the frequency of the signal from a speedometer dynamo detecting the motor speed.
- the motor control system will maintain a 90 rpm distribution speed for a pre-set time, which is longer than the one of phase B, after which the drum speed increase will be enabled till the spin speed is reached, as it is shown by the example in Fig. 1 through the hatched line CE.
- phase B If during phase B an unbalance is detected, the motor control system will cut off power to the motor causing the drum to stop. This action is graphically shown by phase C.
- a first interval of about 10 secs occurs as indicated by D.
- the control system enables the motor and brings it to a speed of about 45 rpm in the phase indicated by E.
- phase F a new stop of the motor and of drum rotation
- phase H a new interval
- phase H the control system starts the motor again (phase I) to rotate inversely to the direction of phases E-F, till the 45-rpm speed is reached and maintained for about 10 secs (phase L).
- phase M a new stop
- phase N a new interval
- Said start, stop and drum motion reverse phases have the purpose of possibly obtaining a distribution of the clothes inside the drum different from the initial one, so as to remove a load unbalance. This occurs practically because said motion stops and reverses cause the clothes to fall down on the lower side of the drum as well as their "mixing", right with the purpose of eventually removing the initial unbalance condition.
- the motor control system carries out a new distribution phase by repeating both phases A and B. If during the new phase B a new unbalance is detected, the control system will then repeat phases C-N.
- FIG. 2 a simplified block diagram shows part of the control circuit of the machine implementing the method according to the present invention.
- MO indicates the laundry washer motor, which generates rotation of a machine drum in a manner known for itself with the aid of belts and pulleys.
- SC indicates in its whole an electronic digital module or system for the control of motor MO.
- MP indicates an electronic microcontroller with an internal clock, indicated by CLOCK, with associated permanent memory means indicated by ROM.
- said microcontroller MP is actually the one available in the digital module SC to control the function of motor MO.
- Memory ROM has some management programs of motor MO codified according to the various phases provided by the operational cycles of the machine, which can be selected by the user through proper control means (eg. an electro-mechanical timer and/or selection keys).
- Module SC specifically through microcontroller MP and relevant memory ROM, manages the motor MO as a function of the signals received from said control organs and other machine components, such as a pressure switch, some push-buttons, a speedometer dynamo, etc.
- the device T indicates a device suitable to generate a representative signal of the rotation speed reached by the drum and consequently by the motor MO during machine operation.
- the device T consists of a speedometer dynamo, but it is obvious that other similar devices can be used for the purpose of measuring rotation speed of both the drum and motor (eg. sensor of magnetic reed type).
- the permanent memory ROM of the microcontroller MP has a proper program available, which will be described later with reference to Fig. 4, to perform the method according to the invention.
- Fig. 3 a simplified diagram shows the flow of drum rotation speeds of a laundry washer implementing the method according to the present invention, during the phases of laundry load distribution, its unbalance and its removal. Also in Fig. 3 time is represented on the axis of the abscissas, whereas the axis of the ordinates represents the speed reached by the washer drum during the various operational phases. According to the method provided by the present invention, a distribution or satellization phase for the laundry load is provided before starting a spinning phase.
- the machine motor is controlled to bring the drum to a satellization speed of about 90 rpm. Upon reaching said speed, this is maintained for a certain time in the phase indicated by B'.
- the machine control system measures the load balance degree.
- the motor control system will maintain distribution speed (90 rpm) for a pre-set time and subsequently enable an increase of the drum speed to reach the spin speed as it is shown by way of example in Fig. 3 by the line CE'.
- the method according to the present invention provides for a decrease of the drum rotation speed from 90 rpm to a speed value allowing the clothes to disatellizite, i.e. to come off the drum walls and fall down to its centre so as not to slow down its rotation.
- This speed decrease phase is indicated in Fig. 3 by reference letter R.
- the speed value for disatellization of the load without decreasing the drum speed is substantially comprised between 45 and 55 rpm.
- the drum speed decrease is simply obtained in the practice by stopping power feed to the motor MO of the laundry washer for a few seconds, till the speedometer dynamo T detects that the motor has reached the pre-set speed between 45 - 55 rpm, as stated above.
- control system SC of motor MO feeds the motor again determining a speed increase to 90 rpm during the phase indicated by A'' in Fig. 3. This speed will be subsequently maintained for a pre-set time in the phase indicated by B''.
- phase B'' the phases of speed decrease (R), increase (phase A'') and distribution (phase B'') can be obtained in a total time of even less than 10 seconds.
- phase R causes the clothes to come off the drum walls to the drum centre.
- a fast speed increase to 90 rpm does not let the clothes collect to the drum lower side; in other words, therefore, before the clothes collect on the drum bottom the spinning force generated by the new speed increase to 90 rpm determines a new satellization of the load, so that drum rotation is not held back.
- phase B'' the control system performs a new check of the load balance degree. If the load is now balanced, the control system will maintain a 90 rpm speed till the signal from the programmer or timer of the machine (not shown in the figure) indicates that the high speed spin phase has started, whereas in case of a still unbalanced load the control system SC of the machine will perform a new speed decrease phase down to 45 rpm (phase R), a new increase phase up to 90 rpm (phase A'') and a new distribution phase (phase B'') verifying the balance degree. Said operational cycle will be repeated as long as the load is not balanced so as to obtain a stable spin.
- the method according to the present invention allows the performance of the operational cycle in a drastically shorter time compared to the known state of the art.
- FIG. 4 shows by way of example a possible block diagram of a part of the logical circuit of the motor of a laundry washing and/or drying machine implementing the method according to the present invention.
- reference number 1 indicates the start block of the program, which releases control to block 2.
- Said block 2 determines the start of a motor speed increase slope to 90 rpm (phase A' of Fig. 2), and then releases control to block 3.
- Such a block 3 is a test block, testing load balance conditions during the distribution phase (phase B' of Fig. 3).
- Said block controls motor feed, so as to decrease the drum rotation speed from 90 rpm (phase R in fig. 3). Then the control goes on to block 10.
- Block 10 is a test block, verifying when the drum rotation speed reaches the pre-set disatellization value (comprised between 45 and 55 rpm), i.e. a speed allowing the clothes to come off the drum walls, however without stopping drum rotation.
- the control Upon reaching said decreased speed (output SI), the control goes back to block 2, which performs a new speed increase slope up to 90 rpm (block 2 or phase A'' in Fig. 3) and a new test of the load balance (block 3 or phase B'' in Fig. 3).
- the method according to the present invention allows an extremely efficient balance of the clothes inside the drum of a laundry washer in drastically shorter times than according to the known technology described at the beginning of the present description.
