After 164 years of development, the washing machine has developed two forms of washing, pulsator and drum, and people's hands are more free from the tedious washing process. However, driven by consumption upgrades and the rapid rise of the new middle class, washing machines can no longer satisfy consumers' deeper pursuit of clothing care and health attributes by "washing with less effort" and "washing cleanly". The addition of washing and other functions has further upgraded the user's experience, but only "one tub" has always been difficult to meet the laundry needs of different people at home and even different clothes, so a partitioned washing machine appeared.
Zone washing machine is a washing machine that integrates two independent laundry areas. Generally, it can meet the washing needs of different families through combination schemes such as double drum or drum + pulsator, matching of the same specifications or sizes, and horizontal or vertical layout. Compared with single-cylinder washing machines, partition washing machines have the advantages of less water consumption, lower energy consumption costs, shorter time and stronger operability when dealing with different groups of people in the home. New selection. According to statistics from Aowei Cloud.com, during the 618 period of JD.com in 2021, the turnover of partition washing products will increase by 55.6% year-on-year, and the sales volume will increase by 107.8% year-on-year. The market of partition washing machines is very good.
At present, the partition washing machine represented by the double drum on the market has received a warm response, but it still faces high barriers at the technical level. The most criticized is that the capacity of the upper drum is too small. In order to accommodate the "double tub" as much as possible, many zone washing machines will directly raise the cabinet shell, but this also increases the risk of high-intensity vibration caused by double eccentric force, which is what we call resonance. When resonance occurs, not only the washing effect of the washing machine will be affected, but also the washing machine will swing left and right, which brings a certain hidden danger of dumping. Therefore, in order to achieve a relative balance, manufacturers can only design the diameter of the upper drum of the zone washing machine to be very small, and reduce the risk of resonance by reducing the volume of the upper drum.
We can see some partition washing machines on the market advertise their large capacity, but they only refer to the total capacity, the upper drum capacity is only 2-3kg, which is obviously not enough, and loses the meaning of partition washing. When we buy a partition washing machine, we need to pay attention to not only the total capacity of the washing machine, but also the respective capacities of the upper and lower drums, whether they can meet our own laundry needs.
In addition, the motor configuration of the partition washing machine is also very important, because to achieve true partition synchronization, the upper and lower do not interfere with each other, and there are high requirements for the performance and stability of the motor, and the washing efficiency and operation of the washing machine. Noise and other aspects also have a great relationship with the motor.
There are generally two kinds of motors commonly used in front-load washing machines, one is BLDC belt variable frequency motor, and the other is DD direct drive variable frequency motor. The BLDC belt variable frequency motor can be regarded as an improved version of the traditional washing machine motor. Although the belt is still used to drive the washing machine drum, the way of driving the drum is controlled by Hall IC instead of mechanical brushes. The DD direct drive variable frequency motor removes the belt and other components and is directly driven by the motor. Compared with the BLDC belt variable frequency motor, the DD direct drive variable frequency motor has higher efficiency, lower vibration and lower noise. The DD direct drive variable frequency motor is used. The partition washing machine will be a better choice, of course, the price of the partition washing machine under this motor will be relatively higher.
The capacity of the upper cylinder and the configuration of the motor are only important reference conditions, and more choices still need to be made according to our specific use requirements. But in any case, the partition washing machine is gradually growing into an important force in the washing machine market. In the future, we look forward to more possibilities that the partition washing machine will bring us.
