The washing machine, which carries the burden of washing at home, is also one of the appliances we use almost every day.
The use of long years, less than seven or eight years, more than ten years, once the choice is not good, washing is not clean, clothing wear and tear, noise and other problems, are very affected the happiness of home life.
So, this issue of the new small residence to bring you the washing machine "10 do not choose", and give in the end how to choose is the right, I believe you read, and then buy a washing machine will not step on the pit.
1、Do not choose the wave washing machine
The principle of the wave washing machine is brutally simple, that is, through the bottom of the wave wheel piece drives the water flow in the clothing rotation, so that the clothing between the friction, clothing and roller friction, so as to achieve the purpose of washing.
The disadvantages are obvious, wear and tear on the clothing, and will cause winding, even if some of the wave washing machine has anti-winding function, but the price directly doubled, the cost is too low to be cost-effective.
Moreover, the wave washing machine does not have a heating function for the water stream, and the overall cleaning strength is relatively weak.
The only advantage is probably that the price is relatively cheap, about a thousand dollars can buy about the same.
And the design of the top flip cover, considered an advantage and a disadvantage, friendly to the elderly, use without bending, but for families who want to have a separate dryer at the same time, it is very inappropriate, can not be stacked, wasting space.
Therefore, for most families, or drum washing machine is more appropriate, not only stacking dryer more convenient, its laundry principle is also more friendly to clothing:.
The washing process is similar to pounding, bringing the clothes to the top of the drum and then dropping them, similar to beating clothes with a mallet at the river in ancient times, without tangling and with less wear and tear on the clothes.
Moreover, the washing process has a heating function that enhances the activity of the enzymes in the laundry detergent, resulting in stronger cleaning compared to the wave wheel.
The only thing is that the price is slightly expensive, but if the budget allows, it is still recommended to choose the roller not to choose the wave wheel.
2、Do not choose the washing and drying machine
Most of the washing and drying machine, are condensing drying, although a top two, save money and space, but many disadvantages:.
- Poor drying effect, long drying time, imperviousness and wrinkles.
- High drying temperatures, which are more likely to damage clothing.
- Drying capacity is small, mostly only 7kg, and no lint filter function, basically clothing lint are in the cylinder wall or rubber ring, especially the family pet, need to clean up often, relatively troublesome.
So, if the family only occasionally have drying needs (a few times a year kind), you can consider an all-in-one machine, other cases, either directly do not, or choose a stand-alone heat pump dryer.
Heat pump type, is the use of heat pump circulation system, so that the condenser and evaporator and the air in the cylinder for heat and moisture exchange, dry hot air to evaporate the moisture in the clothing, wet air in the evaporator condensation, to achieve the effect of dry clothes and water removal.
Compared to the condensing type, it is more obvious for heavy clothes drying, low drying temperature (less damage to clothes), faster drying speed, less noise, higher fluffiness of the baked clothes, and more energy efficient.
The only drawback is the high price, but for families who need drying function, it is still recommended that freestanding is more appropriate.
3, do not choose the small capacity of the washing machine
Some people think that the family is small, you can choose a small capacity washing machine, but in fact, regardless of the number of people in the family, are going to wash four-piece suits, sofa cushions and other large pieces, so 8/9kg or even the following capacity, it is not recommended to choose.
At least 10kg to start, and 10kg on the market has been the mainstream size, if more people in the family (more than 5 mouths), you can also choose a larger, wash four-piece suits, plush toys and so more comfortable.
4、Do not choose the small diameter of the inner tube
The diameter of the inner cylinder of the washing machine should also be noted, the same capacity, as far as possible, choose the cylinder diameter is larger, more in line with the drum high fall cleaning principle, washing effect is also better naturally.
5、Do not choose DC motor washing machine
Washing machine motor, to put it bluntly, the drum is dependent on it to rotate, and DC motor, also called brush motor, belongs to the most basic motor, with low efficiency, loud, imprecise control drawbacks, can not choose not to choose.
The good thing is that at present, DC motors have been largely eliminated, and the mainstream washing machines are BLDC inverter motors, or brushless motors, which are better, quieter and more precisely controlled than DC motors.
When we choose, we just need to pay attention to look at the parameters to avoid stepping on mines.
6、Do not choose belt drive motor
If you have read the parameters of the washing machine, you may also find a description of the motor called DD direct drive motor, and 9 out of 10 home bloggers don't get this concept.
DD direct-drive motor, and BLDC motor is not a parallel relationship (many bloggers have it two to classify), but, DD direct-drive motor is a form of drive, BLDC motor (brushless) is a type of motor, just as you ask which is better for electric cars and 4WD cars? Not the same type, there is no comparison.
To put it bluntly, it is BLDC motor (brushed motor), which can be divided into two kinds, DD direct drive and belt drive.
So how do you choose between a direct-drive motor and a belt-driven motor?
Belt-driven, mature technology, there will be no problems like direct-drive motor: dewatering depends on the algorithm to find the balance, too long, but the disadvantages are also obvious, there will be belt slippage, dewatering noise and other obvious problems.
Direct drive motor eliminates the belt drive, direct motor drive drum, less noise, more flexible control, but too dependent on the algorithm, the algorithm is not good, will lead to dewatering to find balance time is too long.
At present, with the iteration of technology, the algorithm problem can be said to be no longer a problem, more and more manufacturers have abandoned the belt drive, instead of using direct-drive motor, so for ordinary people, the priority can be selected direct-drive motor.
Combining 5 and 6, we can directly choose the BLDC (brushed motor) direct drive motor.
7、Do not choose the low energy efficiency level
Unlike refrigerators, air conditioners and the like, washing machines need to be turned on often, and even if they run every day, they are done for one or two hours, so, in theory, there is not much difference between first and second level energy efficiency.
But we still recommend that, unless the price difference is particularly large, otherwise, can choose a level of energy efficiency never choose the second level, for energy saving more environmentally friendly.
8, do not choose miscellaneous intelligent features
In order to premium or occupy the market, there are now washing machines also have a lot of intelligent features, such as cell phones can be connected, directly on the phone to choose the washing program, booking laundry time, etc., seemingly intelligent, but in fact not very meaningful.
Think about the use of scenarios will know, we need to use the washing machine, it is certainly to put the clothes, that by hand, the button pressed, the phone on the function simply can not be used.
There are also some intelligent drop-in functions, that is, laundry detergent and softener can be poured into the corresponding box, and it will automatically drop detergent or softener during the washing process.
But in terms of current technology, it is more appropriate to call it a semi-intelligent drop, not to mention the accuracy of calculating the amount of detergent by weight, on the degree of soiled clothes, laundry detergent concentration, it is certainly unable to identify, so the accuracy of the whole process is open to question.
In summary, the basic use is not much, such intelligent features can be dispensed with.
9, not overly concerned about the wash ratio
This is also a lot of home bloggers, are confused about the problem, the washing ratio of this data, itself a certain deceptive, and not the higher, the more worth spending money for this.
Let's explain exactly why!
First look at their formula: wash ratio = washing machine wash rate to be tested / standard reference machine wash rate
Washing rate=reflectivity before washing/reflectivity after washing
According to this theory, it seems to be quite accurate, but in fact, because this data is measured by the businessman himself, itself there is a certain "fishy":.
Generally they are tested with the most powerful program to wash, speed, temperature is also adjusted to the highest, rinse and then a two times, the time is also selected the longest, and this program, daily we are rarely used.
Therefore, the washing ratio, can only represent the limit state of the washing ability, the effect of normal washing conditions, it is not easy to say.
Furthermore, the test procedures of different brands, are different, some brands, it uses the most commonly used one to test, and some use the most powerful program to test.
Therefore, there may be a situation where some brands overemphasize the wash ratio, but instead the wash ability is weak, which is why, you will see a lot of cheap brands, but the wash ratio is high, the root cause is here.
Instead of looking at this data, it is more intuitive and reliable to look at the diameter of the barrel in front.
10、Not to be misled by the anti-bacterial function
It can be said that there is no perfect germ removal and antibacterial solution.
Take the market is relatively hot silver ion and ozone bacteria, silver ion bacteria, is the silver ion in the tube at a certain location, as long as the water will be released, can play a certain sterilization effect, but relatively weak, and, over time, the silver ion slowly reduced, the effect of bacteria will be weaker.
Ozone sterilization, that is, the additional ozone generator in the washing machine to achieve the effect of sterilization, and, its sterilization effect is very good, can kill a variety of bacteria, but also extremely easy to dissolve in water, the clothing sterilization is very effective.
But everything has its pros and cons, and its strong oxidation, which can easily lead to accelerated aging of the internal parts of the machine, especially the rubber ring.
So, there is no particularly perfect solution to automatically keep the washing machine clean.
The most effective, or regularly go to dismantle and clean, but the high cost of dismantling, the family frequency is certainly not too high, it is recommended to go with the washing machine high temperature function and soaking tablets to regularly clean.
The cost of effervescent tablets is very low, a few dozen can take care of a year of cleaning problems, as long as you adhere to every month, the cleanliness of the tube can basically be maintained in the long term.
As for the rubber ring, in addition to regular wiping, if there is mold, it should also be treated with mold removal gel in time.
The operation is also very simple, the gel is applied to the moldy area and left overnight to wipe the next day, basically nothing to do.
Written at the end.
In fact, the washing machine is a fully competitive industry, in addition to individual new machines may be overpriced, and some useless smart features will have a premium, in fact, most models are price and experience are positively related, you do not need to worry too much when buying and selling.
