Don't worry about the drum and the pulsator when buying a washing machine, the three parameters are more important, and the right choice is cost-effective
When most people buy a washing machine, they will consider a question: should I buy a drum or a pulsator? But to be honest, for household washing machines, the style of the washing machine has little effect on the washing effect.
The only influence is probably the operation method: the front-loading washing machine is operated squatting, and the top-loading washing machine is operated standing - that's all. Compared with the drum and the pulsator, the following three parameters should be the focus of our attention. Whether you can choose a cost-effective product is all reflected in these four aspects.
Air conditioners and refrigerators have the difference between variable frequency and fixed frequency. There is also a motor in the washing machine, which can naturally be divided into fixed frequency and variable frequency.
The frequency conversion of the washing machine is reflected in the speed (motor strength): the frequency conversion washing machine can automatically change the speed according to the amount of water, the weight of the clothes, the washing mode, etc. Run at low speed when there are few clothes and not too dirty. The more clothes, the faster the speed and the stronger the motor.
Compared with fixed-frequency washing machines, variable-frequency washing machines consume less power and produce less noise.
Back then, our washing machines were always "dancing" while washing clothes, because the motor shook a lot during the work. The current motor technology has improved, and the vibration amplitude is small - but no matter how small the amplitude is, it is still far from the frequency conversion motor.
At present, the driving modes of washing machines on the market are divided into two types: belt drive (BLDC) and direct drive (DD).
Belt drive is a very traditional way: the motor rotates, drives the belt, and drives the runner through the belt.
The direct drive motor is very high-end: the motor rotates and directly drives the runner through the magnetic field (magnetic levitation).
In contrast, direct-drive motors have less resistance. As a result, direct drive motors are more power efficient and produce less noise. At the same time, because of its high efficiency, it can generate higher rotational speed.
The maximum speed of the belt drive motor is 1200 rpm, and the maximum speed of the direct drive motor can reach 1600 rpm. Especially in dehydration mode, the effect of high speed is better - so the dehydration effect of direct drive motor is many times better than that of belt drive motor.
The direct drive motor technology of that year was immature, with the defects of high failure rate and high price. The current direct drive motor technology is very perfect, the failure rate is almost the same as that of the belt drive, and the price is not too expensive.
Each washing machine has a variety of washing modes, such as daily wash, express wash, down wash, wool wash and so on. These modes, it is not recommended to pay too much attention - no matter how many modes, we end up using the daily wash and the express wash.
There are three modes worth choosing:
First, sterilization wash. Direct disinfection through the washing machine saves time, effort and health, so why not do it? The sterilization washing is divided into silver ion sterilization, ultraviolet sterilization, high temperature sterilization and pasteurization.
The first two sterilization modes are not very effective, and can be regarded as "displays" or "gimmicks". The latter two sterilization modes have better sterilization effects, among which high-temperature sterilization does slightly more damage to clothing.
Second, remove mites and wash. The dangers of mites are now known to almost everyone. Compared with brushing with a mite remover, it is not as convenient and fast as a washing machine.
Mite removal mainly relies on high temperature, ventilation, and ultraviolet rays to remove mites, and the effect is good. Moreover, the "mite removal" function does not increase the cost much, so it is a very cost-effective choice.
Third, the barrel is self-cleaning. If the washing machine is dirty, it will inevitably cause secondary pollution to the clothes while washing. You can of course choose to disassemble and wash the washing machine every once in a while, but I prefer to let the washing machine clean itself.
The bucket self-cleaning is a function of the automatic cleaning of the washing machine. Turn on the self-cleaning function of the bucket after each washing, and wash, dry and ventilate the laundry bucket, so that the washing machine can be kept dry and clean, and you can use it with confidence.
