Definitions
- the invention is based on a method for determining the mass of wet laundry in a laundry drum, which can be driven by a speed-controlled universal motor, under Using controller sizes.
- a uniform laundry ring cannot develop because, for example Larger items of laundry are included in the laundry item, which do not lead to uniform fixation in laundry rings are capable, because their mass centers are partly the drum axis are much closer and they are not given the necessary centrifugal force.
- the measurement of the phase angle of the supply voltage is inaccurate because even the smallest deviations of the even number of drum revolutions during the start-up phase impact in great inaccuracies.
- the measurements of the level of the supply voltage require and the phase angle special devices for speed control of the universal motor are not otherwise required.
- the laundry mass is determined in a vertically stored washing drum and the agitator together with a dry one entered laundry items accelerated by a drive motor and a certain time held at a predetermined speed for a long time.
- the shutdown of the Drive motor started a time counter, which measures the time until the motor stops.
- This Time is a measure of the moment of inertia of the accelerated masses that make up the known ones and unchangeable masses of the machine parts can be deducted in order finally gain the bulk of the laundry item. Because of this procedure for achieving Adequate accuracy depends on the measurement of dry laundry it can be applied in a step preceding the washing process.
- US-A-4 782 544 describes a centrifugal process in which the moment of inertia the wet laundry during a spin process is determined to be at each stage of the process the maximum spin speed based on the determination with the final cutting speed the decreasing mass of the residual moisture and only then - if possible - the Increase the speed of the laundry drum.
- To determine the success of the spin only the Periods of two successive acceleration sections of the laundry drum between compared the same speed values in each case. If the difference is zero, then there is none further drainage success can be expected at this speed.
- the invention has for its object the accuracy to improve a method described in the introduction and its implementation, if possible, by dispensing with additional ones Simplify components.
- this object is achieved in that before and / or during the execution of a spin program the laundry drum in a mass determination section within is operated by three phases, in which the first Phase due to a delayed speed increase up to a final speed above the landing speed at which puts the laundry on the drum jacket, and next to but below the resonance speed of the drive system, the second phase has a constant target speed equal to that Final speed of the ramp and in the third phase Drumlessly runs down to a minimum speed, which is still so high that the previously trained one Do not wash themselves or only to a small extent Drum shell peels off, and that from the time when you turn it off of the drive up to the point in time when the minimum speed is reached the length of time is measured, which is a measure of that Mass of laundry is.
- the average power of the drive motor determines which is a measure of the braking torque the drum is that as a variable in mass determination is taken into account.
- this can happen Braking torque on the drum due to flexing of the belt, through bearing friction and through friction losses in the shock absorbers surrender.
- the latter parameter always results then a remarkable value if the drum is unbalanced runs and the resulting deflection has repercussions experienced the shock absorbers.
- Procedure during the execution of the spin program at least one further mass determination takes place can be from the results of individual mass determinations the progress of the spin program can be determined.
- the value from another mass determination with the value one before or at the beginning of the previous washing process mass determination of dry laundry in relation asked to achieve the centrifugal effect in the form of a Determine the value for the remaining moisture.
- the spin process can be stopped depending on the condition. This is particularly advantageous because so far no other Possibility existed at laundry items - especially for those with different absorbency of the laundry - the effect of the spin program as a termination criterion to provide.
- the diagram shows a speed profile, which at the beginning of a Spin process can be applied.
- the laundry drum is initially up to a time t0 from Standstill from accelerated slowly to a final speed n1.
- This speed n1 is above the landing speed nA, in which the laundry items lying in the laundry drum Apply to the inside of the drum shell and gradually generally distribute so that the laundry items placed reasonably evenly around the circumference of the laundry drum are. This keeps the laundry drum imbalance within reasonable limits. These limits can change during he start-up phase A up to time t0 by observing the Uniformity of the speed increase on the speedometer signal or on the control variable "phase angle" of the control device be monitored for the drive motor.
- n1 is below a resonance speed nR that thanks to the system of the spring-loaded and dampened suspended tub unit is determined.
- a vibrating system always has a resonance frequency with which the tub assembly in the present case would swing when the laundry drum would be loaded unbalanced and with one of the resonance corresponding angular velocity would be driven. In this case the vibration amplitudes would be a maximum achieve, with sufficiently accurate measurements of the braking torque are no longer possible on the laundry drum.
- the laundry drum is driven with a Voltage supplied that a constant target speed n1 corresponds.
- this second phase B up to the point in time t1 can be obtained by observing the mean phase angle the speed control device by the drive motor power injected into the laundry drum become.
- This achievement can be said to be within certain limits Limits viewed constantly and from the outset in the further determination of the laundry mass within the third Phase C are required.
- Braking torques on the laundry drum can by the bearing friction but also be given by flexing the drive belt.
- the third phase C begins at time t1 and ends on Time t2.
- the drive motor is switched off at time t1.
- the laundry drum immediately begins to run out, within which their speed up to the time t2 reduced to the value n2.
- the speed is n2 so big that they organized themselves in the laundry ring beforehand Hold items of laundry by the drum jacket or start straight peel off.
- the time period TC between the times t1 and t2 during the phase-out phase C is measured and can be calculated in relation to the previously determined braking torque the amount of laundry contained in the drum Serve (mass).
- the time t1 should be distributed Wash be chosen so that the unbalance mass focus always has the same angle of rotation position.
- the time t1 can be determined particularly easily as a fixed point, that the shutdown is always fluctuating at an extreme value Angular velocity (minimum or maximum) or always at one pass through the set speed in the same Direction is made.
- the speed of the running laundry drum reaches the lower one Speed limit n2, then the motor is switched on again and the spin process started.
- the time period TC between the switch-off time t1 and the switch-on time t2 is measured. Including the either predetermined or determined by the previous phase B. Braking torque of the drum can be from the period TC about the calculation of the moment of inertia of the laundry item the mass of the laundry can be calculated.
- the method according to the invention can advantageously also to estimate the remaining moisture in the laundry post. This can be done during the Spin process and / or at the end of a spin process the process sequence according to the invention applied again and the results of previous applications in Relationship.
- the results used to control the spinning process itself e.g. in such a way that when a predetermined is reached Value for the residual moisture of the spinning process is canceled.
- One at the end of an expired spin process determined value for the residual moisture can in the form of an immediate advertisement or a recommendation displayed for the further processing of the laundry item become.
- the method according to the invention has many advantages over the state of the art. It is easy to implement without expenditure additional components. The results of the mass determination leave a more accurate during the spinning process Detection of unbalance caused by speed fluctuation detection be recorded. This makes it easier to decide whether an ongoing spinning process is interrupted and / or repeated must become. Detection of the laundry mass by the method according to the invention is largely independent of tolerances caused by device components of the washing machine on the water level, the water pressure, the inflow amounts, the vibration range of the tub assembly, the pumping speed and the time period different Process sections have an influence. The mass determination can be done at any time before and / or during the spinning process can be repeated and thus allows a variety of uses the results obtained from it.
