At the end of the wash, I’m all shivering, I do not understand why…

Washing ends with wringing. Many old machines at this stage of operation bounce and rattle, when, for example, the laundry is bunched. But modern models use technology to help avoid this. About them and not only tell the representatives of the largest firms-manufacturers of washing machines.

The machine should have a brain!

Vladimir Rozhkov, ATLANT: “The main thing in this question is the “brains” of the machine Today almost all the machines their electronic modules determine the evenness of laundry distribution over the drum surface and depending on the imbalance level make the required number of attempts to unload the laundry and achieve small imbalance. eventually modules choose the maximum spin speed: the greater the imbalance, the lower the spin speed.

Dmitry Serditov, “BSH”: “All modern machines are equipped with a function to control and suppress imbalance during spinning”.

The washing machine is not a “good horse” and should not jump around! In the standard case imbalance is determined by the unevenness of the drum rotation with a tachometer. Advanced Siemens washing machines have automatic stabilization with a 3D-sensor.

The system consisting of a sensor and microprocessor determines the exact position of the tank and accordingly the drum with the loaded laundry relative to the body.

The time for determining imbalance is significantly reduced, noise and vibration are reduced, and the service life of the machine is increased. Having detected the imbalance, the machine takes measures to eliminate it.

Evgenia Suzdalova, Mabe: “Excessive vibration not only makes annoying noise, but also adversely affects the life span of the machine”.

At the household level, when loading laundry to create the right balance at each point of the drum, to avoid improper distribution of laundry, it can be advised not to exceed the maximum load, and with a small load – to reduce the spin speed.

Machines equipped with a balance control feature automatically control drum balance when spinning. Such a machine makes several slow movements of the drum in the opposite direction, untangling the laundry and distributing it evenly.

If imbalance is not corrected, the machine spins at the lowest speed or does not spin at all. Sabe engineers in Spain have developed an innovative system A.B.S. Advanced Balance System with electronic controls to evenly distribute the laundry inside the drum during the spin cycle.

Installation and loading rules

Kirill Burmistrov, ARDO: “First of all, one should not load too much laundry and level the machine on the horizontal plane.

If your washing machine is designed for 5kg capacity, don’t try to cram 7kg just because you can. Also, don’t forget that there is a different loading limit for each type of fabric. It tends to be higher for cotton, lower for synthetics and minimal for wool.

All figures are spelled out in the manual, and if you read the manual beforehand, you can avoid most of the problems with using the washing machine.

I wouldn’t say that all old washing machines bounce and rattle. Half the time excessive vibration is due to the machine not being leveled horizontally, and there are adjustable feet for that.

The basic technology to avoid unwanted noise and vibrations is automatic balancing. Our washing machines distribute the laundry evenly that allows to get rid of undesirable effects.

Anastasia Godina, VESTEL: “You need to install the washing machine correctly, and only on a hard floor. e. to expose it on a level and rigidly fix legs with locknuts”.

The machine must not be placed on smooth tiles: put a thin but tough rubber mat underneath otherwise the machine will run away when wringing.

imbalance control systems are not only there to reduce noise and vibrations from the washing machine when spinning. Safety comes first.

The most common technology for determining imbalance is special software, of the novelties found their application 3D-sensors, active systems of unbalance control, such as electromagnetic dampers.

Alina Myshkina, Candy: “to avoid the problem of imbalance, you need to follow just a few simple rules: wash bed linen separately from the rest since it is usually the duvet covers and pillowcases which are “responsible” for uneven distribution of laundry , not to exceed the maximum load and wash “heavy” items separately.

The electronics also allow you to monitor how the laundry is distributed in the drum.

If the laundry is bunched and there is a risk of reduced washing efficiency, the machine will make several slow rotations of the drum, trying to distribute the laundry more evenly.

And that’s right about the legs: Candy has made all four legs of its washing machines adjustable.

Ivan Lavrentiev, Hansa: “In our models the machine body is fixed on three shock absorbers”.

As we know from the laws of physics, any object is better able to find equilibrium on three points of support than on two or four.

Proper distribution of counterweights and, of course, electronics that monitor the occurrence of vibrations will help solve the problem.

A special design reduces vibrations

Alexander Uzhgintsev, Miele: “Miele washing machines solve the problem of decreasing the vibrations during spinning by means of many design features”.

The counterweight of the tank is made of cast-iron, it does not wear out at the attachment points with the tank and has no backlash in contrast to concrete designs.

The machine itself is quite heavy about 100kg , so the likelihood of unbalancing is significantly reduced. The tank has reliable shock absorbers the same are on professional machines Miele small class .

If the imbalance sensor is triggered, the machine tries to redistribute the laundry in the tank. The attempt will be repeated a maximum of three times, and if this fails, the spinning will continue at a lower speed.

Thanks to the asynchronous motor, the desired spin speed can be reached almost instantaneously. The machine by a special drum rocking motion optimally distributes the laundry, then – momentarily speed up, and then it is held in the right position by centrifugal force.

Yongbin Lim, Daewoo Electronics: “The intelligent direct drive drastically reduces vibration and noise from drum rotation even when loading a large quantity of laundry into the washing machine.

In Daewoo Electronics washing machines, they use a special “Intelligent direct drive motor”, which provides direct drum drive. This eliminates additional links – belt and pulley, which ensure the transmission of torque from the motor to the drum shaft, that is, the belt and pulley are simply absent in the design.

Thus, the torque from the motor is transmitted directly to the shaft of the drum. This kinematics minimizes unwanted vibration and noise.

And, of course, our washing machines have sensors for imbalance: when it occurs, often because of the mixed laundry, the machine begins to spin the drum in different directions, trying to spread the laundry evenly over the drum. This function saves customers from undesirable consequences associated with breakdowns of major assemblies and units of the washing machine.
