Shiatsu drum in a washing machine. What is a honeycomb drum in a washing machine? My rating of Candy models

Which drum in a washing machine is better - stainless steel or plastic? and got the best answer

Answer from Lisichka[active]
We had an important criterion from which the drum will be made in the machine - they chose it from stainless steel. Since the budget for the washing machine itself was not very large, it was generally difficult to choose. A stainless steel drum is much more expensive than a plastic one. On the market they found an Atlant machine with a stainless steel drum up to 10,000 rubles.

Answer from Olga osipova[guru]
the price of stainless steel is not much more expensive than plastic - buy with a durable stainless drum

Answer from Drinker of your dreams[guru]
metal-plastic is the best solution

Answer from K-stimul[guru]
Well, find at least one who will say that the plastic drum is broken, worn out, etc.
If the machine breaks down, then it is certainly not because of the drum.
You will not wash irons and meat grinders ...
For 10 years, a machine with such a drum is enough, and if it breaks later, you can buy a new one ..

Answer from Olga Pluzhnikova[guru]
Of course, stainless steel, although more expensive.

Answer from Vladimir Krivosheev[guru]
Best of all (in terms of reliability and durability) are stainless steel drums. Plastic drums have appeared relatively recently and it is too early to talk about their reliability. But I would choose a time-tested stainless steel. Still, you take the car not for a year or two.

Answer from 3 answers[guru]

Hey! Here is a selection of topics with answers to your question: Which drum in a washing machine is better - stainless steel or plastic?

They have a drum made of stainless steel. Their differences are only in the differing surface of the drum. Washers with a honeycomb drum are designed to provide gentle and delicate cleaning of fabrics from dirt, while not compromising the quality of the fabric.

Design features of the honeycomb drum of the washing machine

This technology was patented by the German manufacturing company Miele, which produces household appliances of the highest (premium) class.

On the surface, which is located inside the drum, there are slightly convex hexagons with angles of 120 degrees.

We can say that in appearance they resemble a honeycomb.

In order for the water in the tank to circulate, very small holes are located at the edges of these regular shaped hexagons, the size of which is much smaller than in the standard washing machine.

The main differences from the standard drum

provide holes for water circulation around the entire perimeter and area. Their diameter is such that when squeezing at high speeds, the fabric is pulled into them due to centrifugal force. In addition, the material during the washing process is subject to friction against the walls themselves. This is rather badly reflected in the further appearance of things: they cease to look like new, and unloved spools appear on clothes.

In devices with a honeycomb drum, due to the efficiency of the structure of the inner surface of the drum, a water film is formed on the “honeycombs” (convex parts). So, the laundry during the washing process does not come into contact with the holes that are located in the concave part.

Due to this, wear and deformation of fabrics is reduced even at high speed. Such a surface even outwardly seems softer and smoother, and the holes are much smaller in diameter than in standard counterparts. In addition, this structure also prevents the drain system during the washing process (buttons, coins, bra bones, etc.).

For this reason, we rightly note that this technology is not only extremely sensitive to almost all types of fabric, but also protects the “insides” of the machine from external influences and unforeseen breakdowns.

Pros and cons of a honeycomb drum washing machine

The honeycomb drum has many advantages. Here are some of them:

The only, but quite tangible minus is the high price. And this is not surprising, because the latest technologies that make life much easier should be paid.

Many consumers do not agree and are not going to overpay, so they prefer cheaper devices, or analog devices at a lower cost. In any case, no one can dispute the superiority of this machine.

Diamond washing machine with honeycomb drum

also positions its cars as devices with honeycomb drums, but they have a slightly different structure. And the name of this model - "Diamond" - in translation means "diamond".

The drum is made of convex parts, as in Miele machines, but in this case they are quadrangles, on the tops of each of which there are holes of small diameter.

In the drums of a new technology called Diamond +, the holes are moved to the concave part, which has already become more similar to the Miele design. The edges of such "honeycombs" have the shape of a light wave for a smoother glide. Compared to conventional machines, this drum also treats things more carefully, protecting against the appearance of spools and other damage to clothes.

The technology of the honeycomb drum in a washing machine is still better than that used in conventional devices. It not only prevents wear and tear of things and has a long service life, but also saves water and electricity.

When choosing appliances for the home, most of us try to give preference to well-known brands. Kandy washing machines began to be actively advertised more than 10 years ago. Since then, the manufacturer has gained recognition and a very positive reputation. More and more consumers began to trust the Candy technique. Due to the high quality of products and reasonable prices, the brand has confidently taken its well-deserved place among the world leaders in the production of household appliances.

The history of the Candy brand began in 1945 in Italy. After the Second World War, life in many cities and countries began to gradually improve, and the population began to actively equip their way of life.

It was in this "wave" of demand for various kinds of household appliances that the enterprising Fumagalli brothers - Niso, Enzo, and Peppino (Niso, Enso, Peppino Fumagalli), who live in a small suburb of Milan, opened a small workshop.

However, the idea of creating an automatic washing machine that could wash and wring out clothes on its own was born even earlier, in the head of the brothers' father, Eden Fumagalli. Before the war, Eden owned a whole network of OMEF mechanical workshops, developing and repairing, mainly, industrial and agricultural machines. But years of devastation bankrupted Eden Fumagalli's company.

The sons decided to make their father's dream come true: they created their own workshop and within a year developed the first model of a washing machine, calling it very simply - "Model 50" (Model 50). Of course, she was far from the automation that we have now, but at that time the device was a real breakthrough.

In 1946, the family dynasty decides to present its development at the Milan Household Appliances Fair (Milan Fair). The machine was a huge success and Eden Fumagalli created new company Candy Elettrodomestici s.r.l., which later grew into the Candy Group holding.

In 1954, the Kandy company produces the first semi-automatic washing machine that can wring out clothes on its own. In the same year, the owner of the company opens his first foreign production in France. By the 80th year, Kandy conquers the world market and begins to produce not only, but also dishwashers, microwave ovens, refrigerators and much more. Large factories for the production of Candy household appliances appear in many countries. The development of the holding continues to this day.

Advantages and disadvantages of Kandy washing machines

disadvantages

One of the most frequent marriages in washing machines of this company is the control unit: some programs may start to fail, sometimes the settings go astray and the like.
More budget models have a low-quality case, prone to chipped enamel, corrosion, and scratches. best quality leave much to be hatches of cars.
The Kandy technique is sensitive to voltage drops. Many breakdowns and malfunctions occur precisely after power surges.

Despite some disadvantages, which, however, any manufacturer has, washing machines from Kandy are popular with our consumers. The percentage of factory defects in these washers is very low.

Features of Candy washing machines

Among the model range there are a lot of devices with a volumetric drum, with a capacity of up to 8 kg. Those who like large hatches will also find acceptable models among Kandy washers.

In the latest lines, the manufacturer offers models equipped with Smart Touch technology, which allows you to control the machine remotely: from a smartphone or tablet based on the Android OS.

In narrow washing machines-Candy Grand Evo machines have a Mix Power System. By activating this function, you can wash things of different colors at the same time, without worrying that they will shed.

The company's specialists have developed a unique Shiatsu drum coating that improves the quality of washing.

The best models in the Kandy line

I will buy a drum with "bee honeycombs"!

"BT": how do they choose a washing machine now? Someone leads to a familiar brand, and someone corrosively delves into the very essence of things: technology, design, materials.

If you were buying a typewriter, would you dig to the tank and drum, to materials and technologies?

K. Burmistrov,Ardo: I would think about this in the third place.

First decide - frontal or vertical? Narrow or full size? How much laundry will you load?

An equally important question is: how much are you willing to spend? Don't expect top quality from the cheapest model. And, on the contrary, a heaped up device is not sold at a bargain price.

And in the third place, as promised, you can think about materials and technologies.

I advise you to think first of all about the drum: it must be balanced so that an excessive load does not fall on the bearings during rotation. And the surface of the drum should be well treated so that the laundry wears out less during washing.

E. Suzdaleva,Mabe: the choice of a washing machine in our conditions is usually limited to free space in the kitchen or bathroom.

For small apartments, top-loading machines are great. Drums with soft opening of the doors and parking of the drum with the doors up are especially convenient. In this case, when taking out the laundry, you do not need to strain every time, rolling the heavy drum with your hands.

If the soul lies nevertheless to front loading, pay attention to cars with an inclined arrangement of a tank. Laundry is obviously more convenient to lay here, and the quality of washing and spinning is better, since the laundry inside the inclined drum is mixed more intensively and thoroughly.

D. Serditov, BSH: plunging into the jungle of metal, rubber, plastic and other technology, you run the risk of not seeing the forest for the trees.

The leading manufacturers are technologically approximately on the same level. But the objective parameters are much more important: dimensions, feature set, cost. Hence the basic rule: start choosing from the main.

V. Rozhkov, Atlant: and I would advise the most corrosive buyers to delve not so much into the intricacies of technology, but into the manufacturer himself. It's one thing - a screwdriver assembly under a license, and quite another - a native, proprietary production.

It is very important how the company is managed, how the technological process is debugged, how the quality control system works. As they say, the stronger and more accurate, the more convenient and expensive. This is where the high cost of well-known brands comes from.

A specific example: you can hardly hear the car even during spinning, if the back wall of the stainless steel tank is insulated, and the vibration of the tank can be sharply limited if its imbalance is detected and eliminated automatically.

All these are questions of technology. And where are they resolved, as expected? The answer, I think, is obvious.

A.Uzhgintsev,Miele: It is generally accepted that the essence of washing is the friction of the laundry against the walls of the drum. The stronger the friction, the cleaner the laundry. But in fact, friction is an insidious enemy of clothing. Friction exhausts, frays the fabric, gradually turning it into tatters. All serious manufacturers strive to get rid of such a "grater effect".

We have kept it to a minimum. The surface of the Miele drum consists of "honeycombs" - small convex hexagons. During washing, due to the relief surface, a thin water film is formed, as a result, the laundry gently slides along the drum and does not experience barbaric overloads.

As you know, when welding, the strength of the metal decreases. Therefore, our drum does not have a single welded part, it is made by rolling. And the honeycomb construction makes the drum even more rigid, durable and practical.

By the way, the Krefeld Institute for Applied Research (WFK) conducted a comparative analysis of a honeycomb and conventional drums. With the same load and the same washing mode, the cellular version spent much less water, electricity and detergents. Here you have technology, economy and ecology!

A. Myshkina,Candy: The quality of the drum directly affects the durability of the entire machine, its most important characteristics - the noise level and the quality of the wash.

Candy drums are also made without bolts - we use vibration technology (vibration up to 100 Hz), which greatly increases its strength and reliability.

A. Godina,Vestel: we can safely attribute tank leaks to force majeure breakdowns. Therefore, when choosing a model, I would pay attention to the material from which its tank is made.

The main requirement for a drum is endurance. This is a rotating element, and it must withstand repeated loads, taking on board a mass of laundry.

Even at high speed, the axis of the shaft and the axis of the drum must match perfectly, since even a fraction of a degree deviation will cause take-off rumble and hard rock-style grinding.

This usually happens if the technology is broken, if the center of gravity of the drum does not fall into the top ten, as a result of which a destructive backlash occurs.

Is the plastic tank replacing the steel one?

"BT": Let's talk about the materials from which the tanks are made. The first thing readers ask: should I choose stainless steel or something else? They are primarily concerned with the reliability of the design and protection against leaks. And what else affects the choice of material for the tank, why are manufacturers increasingly moving away from classic stainless steel?

E. Suzdaleva,Mabe: they began to move away from classic stainless steel when an alternative appeared - polymeric materials.

Of course, a stainless steel tank is much more durable (they are almost always installed on washing machines with high spin speeds), but they also make more noise.

Plastic tanks have a lot of advantages: lighter weight, low cost, silent and economical operation - all this is a consequence of the fact that polymer walls are much better insulated. But they are more fragile than steel.

Therefore, now more and more tanks are made of metal-plastic: the back wall remains steel - this increases the service life, and everything else is made of plastic - this successfully reduces the noise level during washing and spinning.

I. Lavrentiev,Hansa: having collected information about different tanks, many consciously choose the cheaper one - plastic. These are strong arguments if plastic retains heat better, reduces energy consumption and noise levels.

However, the top segment of washing machines remains true to stainless steel. Prices in the premium class are, of course, much higher, since the steel tank here turns into a technological masterpiece. Wealthy buyers are still willing to pay well for the high quality and durability of equipment.

By the way, in the mass segment for a long time they also used a steel tank coated with a stainless layer. The technology is inexpensive, but the stainless layer quickly cracked, chipped and the tank simply rusted.

A.Uzhgintsev,Miele: until a material was invented that would completely replace steel in tank construction. You can, of course, use some modern alloy. But the tank will turn out to be more expensive than gold. Almost all manufacturers using plastic components in the tank are primarily aimed at reducing costs. And the most serious drawback plastic parts- reduced rigidity, fades into the background.

D. Serditov, BSH: metal drums are now made of high quality alloy steel, which allows them to withstand enormous loads: mechanical, chemical and thermal. In the Siemens line there are also polymer tanks made of polynox - this is a proprietary material with low thermal conductivity, reducing energy consumption and noise levels, and also not subject to any corrosion.

A. Godina, Vestel: in the manufacture of the drum, such concepts as molding, drawing, flanging are important, the metal must stretch well, not have cracks and breaks.

In recent years, new smelting methods have been applied to improve the quality of steel. Steel becomes more ductile and cheaper. In the recent past, stainless steel was too hard and hard, requiring high costs to process it. Higher costs - higher price. And manufacturers began to switch to polymer parts.

Polymers - in addition to their purely consumer advantages, are a very technological material: flexible, plastic, which makes it possible to accurately observe geometric parameters. Hence the lower production cost. And the mechanical strength of the plastic drum is now enhanced with the help of reinforcing additives.

A. Myshkina, Candy: in addition to stainless steel and plastic, tanks are also sometimes made of enamelled steel. However, the main disadvantage of enamel - fragility, speaks for itself. Candy uses Silitech polymer material - it has high wear resistance and excellent sound insulation. It is a lightweight composite polymer that does not corrode and is environmentally friendly.

As colleagues noted, the composite tank is very reliable, durable (almost as good as stainless steel in these characteristics), as well as silent and corrosion resistant.

K. Burmistrov, Ardo: all manufacturers started with stainless steel, but gradually began to switch to plastic. And this is not just a tribute to fashion.

Modern plastics are composite, very technologically advanced, they can be given any shape, they are strong and durable, and most importantly, plastic is cheaper than metal.

Ten or more years ago, only metal could provide reliable sealing. Therefore, any seller in any store advised a stainless steel tank. But progress does not stand still. Modern plastic also holds water very well.

For example, ARDO plants use the vibration welding method for sealing. This technology allows you to make a single whole from two parts. So there can be no talk of any leaks.

Why are holes made in the drum?

"BT": At the forum of one well-known company, a certain meticulous housewife, in all seriousness, told how she counted the holes in the drum of her car and that of a neighbor, in whose typewriter there were as many as five more holes. To the general amusement of the members of the forum, the offended lady asked to change her car. But seriously, does the shape, location and number of holes and blades in the drum matter?

D. Serditov, BSH: with a decrease in the diameter and number of holes, the wettability of the laundry decreases, there should be an optimal balance. Siemens uses the proprietary drum varioSoft. Its surface is covered with protrusions in the form of a droplet - gentle or intensive washing is possible in it - at the request of the hostess.

In addition, each asymmetrically shaped drum grip has steep and flat sides. Depending on which direction it rotates, the linen experiences a strong or, conversely, gentle mechanical impact.

E. Suzdaleva, Mabe: the safety of linen is affected not so much by the quantity as by the design of the perforations in the drum.

It is better to have more holes, but smaller diameter. This geometry enhances the strength of the structure and provides more gentle washing, and at a high spin speed - protection against creasing.

Small holes also protect the tank from small items hidden in the pockets of unwashed clothes.

Cellular drums have become especially popular now. Hexagonal convex "honeycombs" favorably affect the safety of linen. During the washing process, it does not unnecessarily deform, does not drag into holes, does not stick to the walls - thus the “grating effect” is reduced. In addition, the honeycomb design of the drum increases its mechanical strength.

A. Myshkina, Candy: Of course, the design of honeycombs and the drum as a whole affects the result of washing.

Candy uses an enlarged drum with Shiatsu Massage technology in its machines, which allows you to take care of the laundry without losing the quality of the wash.

The size of the holes is reduced to 3 mm, and their number is increased by 9 percent - up to 2556 (in a 40 cm deep washing machine).

This technology gives an advantage at all stages:

During washing, the laundry is better distributed inside, the fibers of the fabric “relax”, as if on a massage, and frequent holes help water and detergent to penetrate the “essence of things” faster and remove even old stains;

During rinsing, foam and detergent residues are more easily and completely washed out of the drum;

During the spin cycle, the reduced openings protect the laundry from unnecessary damage.

My gentle and affectionate circle

"BT": thin knitwear is in fashion, things that are complex in cut and rich in decorative details, the finest cashmere. That's why gentle and delicate programs are more relevant than ever, as are the easy iron, anti-wrinkle, etc. options. What role does the drum play in these programs?

E. Suzdaleva, Mabe: most of the "easy iron" and anti-crease programs are based on the fact that the rinse is used a large number of water, and after the spin phase, the drum continues to rotate slowly. Thus, the laundry does not twist and does not gather in a heap, but is distributed more evenly and does not wrinkle much.

The simplest defense against wrinkling is to stop rinsing. This function allows you to remove the laundry from the machine before the spinning phase or postpone this phase - while remaining in the water, the laundry will not wrinkle.

K. Burmistrov, Ardo: the main requirement for the drum is the absence of sharp edges and burrs. Currently, this condition is met in the vast majority of models.

The main load in this case falls on the electronic control unit: it is he who determines at what speed and in which direction the drum needs to rotate or, conversely, when it needs to stop.

A. Uzhgintsev, Miele: the honeycomb of our drum has a diameter of only 2.1 mm and is not made by drilling, but by stamping. When spinning, even at the highest speed, the laundry does not penetrate the drum and is not damaged. The edges of the holes are always even. That's why honeycomb drum Miele allows you to wash items even with the "hand wash" symbol.

An interesting fact: Miele is the world's largest consumer of… hosiery. Women's tights are known to tear at the slightest contact with uneven surfaces, which is why this delicate material was chosen to test the quality of the Miele honeycomb drum.

Each of our drums passes the "pantyhose test": a lady's stocking is passed over the entire surface of the drum, and if at least one puff is formed, the drum is rejected.

A. Myshkina, Candy: the "easy iron" mode significantly reduces the number of wrinkles after washing. Candy washing machines use the following “no wrinkle” mode technology: the temperature gradually decreases during the cycle and this cooling prevents thermal “creases” on the fabric. And the slow rotation of the drum - at the final phase of washing, straightens the fabric.

When choosing the “delicate wash” and “hand wash” programs, water remains in the drum at the end of the cycle - this is insurance in case the laundry lies in the drum for a long time after washing. Water is needed so that dry creases do not form on clothes. To complete the wash, you need to press the button, drain the water and be sure to get clean and soft linen.

Direct drive on the "crooked goat" will not go around?

"BT": It often happens: at first the technology is considered ineffective, and then a company is found, brings it to mind and begins to position it as the best of all possible alternatives.

This was the case, for example, with wet hair removal, which was considered unhygienic for a long time, but has become a real trend in recent years.Doesn't the same story repeat itself with direct drive in washing machines?

A.Uzhgintsev,Miele: let's clarify what consumer benefit this technology provides. Usually declared extraordinary noiselessness and durability.

Yes, direct drive is somewhat quieter because it has fewer rotating parts. However, in a modern washing machine, the drive mechanism is not the main source of noise.

A much greater noise effect is given by vibration that occurs at high speeds, as well as incidental causes - for example, the metal clanging of buttons or rivets on the drum hatch. Such sound accompaniment is not related to the design of the drive and must be eliminated in some other way.

Therefore, Miele cars have a special service: the "Especially Quiet" function, the unbalance elimination button, noise and vibration isolation and other technological features.

Why, for example, the elimination of imbalance significantly reduces extraneous noise? The reason is simple: the center of gravity of wet laundry, coupled with water, at some point begins to strongly deviate from the axis of rotation of the drum. If you do not eliminate this offset, the car starts to vibrate and bounce out of the blue, making an unpleasant rumble.

This technological cause of noise has been eliminated in almost all modern machines - with the help of special sensors that constantly monitor and correct the imbalance, correctly redistributing the laundry in the drum.

Now for the second benefit of direct drive, durability.

So far, “not too many hours have been flown” to trump durability. There is simply no experience of long-term operation of such machines.

In addition, our engineers conducted laboratory tests: direct drive life tests showed a high probability of premature failure of the oil seal in the bearing, and this is fraught with oil leakage directly into the laundry drum.

Repair will not be cheap, since the entire tank with the drive will have to be changed. The cost will be comparable to buying a new car.

Perhaps in the future this problem will be resolved. But so far, direct drive technology is not perfect enough.

E. Suzdaleva,Mabe: direct drive certainly has its advantages over conventional belt drive - a stronger design and quieter operation. However, in production, direct drive is more expensive, which increases the cost of the washing machine.

And you can't get away from the repair problem. If, God forbid, the direct drive breaks down, the whole engine will have to be changed, and even with a tank to boot. And in engines with a conventional transmission, any part can be replaced one by one. Most often this is a belt worn out from time to time, other breakdowns are very rare. Feel the difference!

So, our attitude to direct drive is still ambiguous. We continue to seriously work on improving the drive system. If we can offer the consumer the best way and at no extra cost, of course, we will do it right away.

A. Godina,Vestel: Although the direct drive design is more compact, eliminates the weak link of the belt drive, ensures quietness and reduces power consumption, it is still a very big question how a direct drive motor will behave and how quickly it wears out from vibration and friction.

V. Rozhkov, Atlant: the main problem of the widespread introduction of direct drive is a technology that requires the highest culture of production in assembly, minimal deviations from the characteristics and cosmic accuracy in details. Otherwise, the reliability of the washing machine is low.

K. Burmistrov,Ardo: any company should invest in scientific and technical research, develop and improve.

As a rule, surveys are conducted in parallel in different directions. And if you manage to create something new and actually improve the consumer properties of products, be sure that competitors will immediately take note of the innovation and will soon do something similar.

With direct drive, in my opinion, the situation is different. It's more of a publicity stunt, like a square loading hatch or a slanted control panel.

I. Lavrentiev,Hansa: agree. Direct drive technology is promoted for marketing purposes.

A. Myshkina,Candy: we use inverter motor technology, which has the same advantages as a direct drive motor and keeps the washing machine compact.

The inverter motor saves up to 15 percent of energy when washing, silent, reliable and durable.

D. Serditov, BSH: Siemens washing machines also use an inverter motor - iQdrive. Thanks to the absence of brushes and precise electronic control, energy losses are indeed significantly reduced.

The combination of high-precision sensors, the latest electronics and the precise operation of the new iQdrive ensure the best washing result, including stain-free stain removal, better rinsing results, and gentler laundry care.

The absence of brushes in iQdrive also significantly reduces internal friction, so the motor runs very quietly even when spinning. Can be washed even at night!

It is important to note that in the case of a standard drive, the drum and motor are parts of the same system, they are attached to the tank, tension or sagging of the drive belt is simply excluded.

Most modern models of washing machines have stainless steel drums. The differences are only in their different inner surface. Washing machines with a honeycomb drum are designed to provide a delicate and gentle treatment of fabrics, without compromising the quality of soil removal.

The technology is patented by the German company Miele, which produces premium household appliances. On the inner surface of the cylindrical structure are convex hexagons of regular shape. In their appearance, they resemble honeycombs. For water circulation, small round holes are located along the edges of the hexagons, the number and size of which are much smaller than in a conventional drum.

How is it different from a regular drum

The traditional design provides holes for water circulation throughout the area. Their diameter is such that when squeezing at high speeds by centrifugal force, the fabric is pulled into them. In addition, during the washing process, the material is already subjected to constant friction against metal walls. This negatively affects appearance things: they are washed out, spools appear on clothes.

In washing machines with a honeycomb drum, due to the efficient design of the inner surface, a water film forms on the convex parts (honeycombs). During washing, the laundry practically does not come into contact with the holes located in the concave part, this prevents wear and deformation of fabrics from friction, even when spinning at high speeds. The "honeycomb" surface even at a glance seems to be smoother, the holes are much smaller in diameter. In addition, this structure prevents small objects (buttons, coins, runners, underwear bones, etc.) from entering the tub and drain system of the machine during the washing program, which can subsequently cause knocking during the spin cycle.

Therefore, it is fair to say that this technology not only takes care of any type of fabric, but also protects the components of the washing machine from the external influence of objects that can get into it during the washing process.

Otherwise, the principle of operation of both conventional and "honeycomb" designs is similar.

Advantages and disadvantages

The honeycomb drum has a number of significant advantages:

Fabric care. Water with detergents dissolved in it remains in the cells during the washing program and forms a thin film. Due to this, the process of friction of things against metal walls is reduced, so the material is not subjected to much wear.
Strength and durability. This is a cast construction, manufactured by rolling. There are no welded parts in it, due to this, the service life is increased.
Resource Saving. The Miele expert group, when testing their invention, proved that the honeycomb drum consumes electricity and water much more economically than a conventional one.

The only downside is the price. Indeed, in most cases, you have to pay for innovative technologies that make life easier. Although not all consumers are ready for this and prefer to choose cheaper devices or analog models at an affordable price. But the superiority of few will undertake to challenge.

Honeycomb Drum Diamond

Samsung also positions its drums as cellular, but their structure is somewhat different. And the name "Diamond" itself is translated as a diamond. The drum is made up of convex quadrangles, on top of which there are holes of reduced diameter. In the drums of the new generation Diamond +, these holes have already been transferred to the concave part, like in Miele. For easy sliding of linen, the edges of the "honeycombs" have wavy shape. Compared to the traditional design, such a drum is more gentle on delicate fabrics, protects things from pilling and damage.

Technology such as the honeycomb drum is undoubtedly superior to conventional technology. It not only prevents the wear of washed items as much as possible and has a long service life, but also saves consumed resources. But it should be noted that any drum, regardless of the technology used in its production, needs regular cleaning from dirt. This will help extend its service life and keep the laundry clean, because during the washing process it actively rubs against the walls of the drum.

Some models of machines, for example, from LG, have a built-in drum cleaning function.
