とにもなりかねない。During each washing process of a domestic washing machine, the laundry contained in the rotating drum of the washing machine tends to be distributed along the inner edge of the drum, sometimes in a very non-uniform manner. When an imbalance moment that causes an abnormal magnitude of vibration and mechanical stress is generated and the vibration and mechanical stress exceed a predetermined critical level, in particular, the vibration level of the washing drum portion of the washing machine is If the drum is so high that it collides with the outer casing of the washing machine, the mechanical structure of the washing machine may be damaged.

実行される。From the viewpoint of preventing such a state, the magnitude of mechanical stress generated each time is immediately predicted depending on the speed at which the drum actually rotates, and the mechanical stress reaches a critical level. It is necessary to prevent it from occurring. This usually involves changing the speed of rotation of the drum in a suitable manner, i.e. more evenly distributing the laundry in the drum while alleviating and even eliminating the imbalance due to the uneven distribution of the laundry. It is carried out by a method of reducing the rotation speed of the drum to the extent that

ある。Even when the laundry is substantially in equilibrium, in the case of a very large amount, such a phenomenon may occur, which impairs the integrity of the washing machine or causes it to malfunction. Even if the operation is not disturbed, it is highly possible that the vibration of the washing machine is transmitted to the floor where the washing machine is installed, and from the floor to the entire room or the entire building. Actually it became clear experimentally. Such a phenomenon is usually negligible in the case of traditional types of solid and extremely sturdy building structures, whereas relatively elastic rooms made of lightweight materials or In the case of buildings, it can be uncomfortable.

詳しく説明しない。At time T0, the drum is about to finish the last wash phase BV at low speed and the direction of rotation is periodically reversed. At time T1, the low speed washing step BV is completed, the drainage pump (not shown) is energized, and the low speed spinning dewatering step is started. At the end of this stage, at time T2, the mechanism for monitoring the imbalance of the laundry in the drum is activated. If the detected unbalanced state is smaller than the predetermined value BC1, the rotary dehydration step continues after the time T2. On the contrary, if not, the rotary dehydration step returns to the time T0. The steps are started again. Low speed rotation BV, low speed rotation dehydration stage CBV, until a value less than a predetermined value BC1 is reached, or the number of repetitions of the procedure reaches a predetermined maximum number.
Then, the above procedure of checking the unbalanced state of the laundry is automatically repeated. In any case, the procedure is substantially known in the prior art and will not be described in further detail here.

The garment under the influence of its weight due to its inclusion is partly pressed into the holes provided along the cylindrical surface of the drum to drive the moisture from the garment out of the drum. This effectively “sticks” the garment to the wall of the drum, so even if the drum speed is significantly reduced below the minimum spin dewatering speed, the garment will “unstick” even partially. It is to prevent an inconvenient state that it is difficult if not impossible to do.

いて結果的に特に有利な役割を果たす。Immediately after the momentary spin dehydration step, a time T4
The rotation speed of the drum decreases to a low rotation dehydration speed CBV or a similar speed so as to correspond to
The spin dewatering stage in MV is started. This step is performed over the period from time T5 to time T6. In practice, by performing the instantaneous spin dewatering immediately before the medium speed spin dewatering step CMV, the medium speed spin as would typically occur if a preliminary instantaneous spin dewatering step was not previously performed at time T3. It was empirically revealed that there is no tendency for clothes to be pressed into the holes provided on the wall surface of the drum during the dehydration stage. These phenomena consequently play a particularly advantageous role in the dehydration process, as explained in more detail below.

不均衡状態の測定と確認とが行なわれる。At the end of the medium speed spin dewatering step CMV, the rotation speed of the drum is reduced to the speed of the low speed spin dewatering step CBV, and is kept at the speed during the period from time T7 to time T8. First, the imbalance of laundry is measured and confirmed.

最初から、すなわち時間Ｔ0 から行なわれる。When it is found that the laundry imbalance exceeds a predetermined level BC2, as a practical matter, it is actually required to further speed up and safely initiate any subsequent spin dewatering stages. The total spin dewatering phase is carried out again from the beginning, ie from time T0, since it is in a state of imbalance above a certain level.

ることが必要になる。At this point, the benefits of the flash spin dehydration are fully understood. In fact, in this case, the garment is not press fit into the hole of the drum, allowing it to fall freely on the bottom of the drum, but if the garment is "sticking" to the wall of the drum, Obviously, it is impossible to drop clothes even by spinning at a very low speed. Therefore, in such a case, even if the unbalanced state is alleviated, it is necessary to accept the actual unbalanced state as it is, and at the same time, the normal operation of the washing machine and the complete structure In order to avoid the condition where significant vibration due to low-amplitude high-frequency vibration that is transmitted from the base of the washing machine to the floor and finally to the entire room is generated in the washing machine even if it does not matter as far as the property is concerned, just spin-dry it. It will be necessary to limit the speed to a speed below the maximum speed VCmax in the dehydration stage.

る。In conclusion, therefore, when the initial instantaneous rotary dewatering is carried out, the laundry is washed to such a level and degree that the final rotary dewatering step can be started at the highest speed possible without transmitting excessive vibration to the floor. It is possible to repeat the procedure to balance the water, but if this is not done, the problem is that the highest speed spin dehydration of the drum causes severe vibration or the slow speed spin dehydration of the drum reduces the vibration. It can be asserted that one has to accept any of the problems of reduced effectiveness.

The invention can also be modified in further advantageous manner. As a practical matter, if the unbalanced state detected in the time period T7 to T8 is less than the predetermined maximum allowable level BC2 and exceeds the predetermined intermediate level BC3, it is slightly lower than the maximum spin dehydration speed VCmax, Subsequent final rotary dewatering steps can be carried out at a suitable speed value VC1 which ensures an acceptable rotary dewatering result without generating the unwanted vibrations transmitted by the washing machine.

つことにあるということが、完全に理解されよう。The first imbalance measurements made in the time intervals T1 to T2 are such that even when a medium amount of laundry is being processed, the imbalance of the washing machine will occur in the later time intervals T5 to T6. This is necessary from the standpoint of avoiding excessive imbalances that could damage the washing machine during the medium speed spin dewatering phase that takes place, but is then followed by a slow speed spin dewatering phase at time intervals T7-T8. The purpose of the imbalance measurement is to bring the laundry imbalance to a low level so that the vibrations transmitted from the washing machine to the surrounding building structure during the subsequent high speed final spin dewatering stage are within predetermined limits. That will be fully understood.
