Shulou(Shulou.com)11/24 Report--

Nowadays, all-in-one washing and drying machine has become a choice for more and more families. as a leading brand in the field of intelligent cleaning in China, Stone Science and Technology has recently launched its first all-in-one washing and drying machine, the stone molecular sieve all-in-one machine H1. This is also a new category in addition to self-cleaning sweeping robots, floor-sweeping robots and hand-held wireless vacuum cleaners.

With the release of the stone molecular sieve washing and drying machine H1, stone has almost achieved full coverage of products in the field of intelligent cleaning.

The release of the integrated stone molecular sieve washing and drying machine H1 also carries the thinking of stone science and technology in the field of intelligent cleaning for many years, which is different from the mainstream condensation and heat pump drying schemes on the market. Stone science and technology chose the third technology route-the industry pioneered molecular sieve low temperature drying technology.

Written before the evaluation: washing and drying all-in-one machine knowledge small science all-in-one machine on the market is mainly divided into condensing type, heat pump type two drying technology solutions, condensing type is air drying through heating device, which can be simply understood as "blower" drying; heat pump type is in the condensing type on the basis of the addition of compressors and other equipment, through the condenser and evaporator circulation cold and warm gas for drying, the latter is more expensive.

Condensing type mostly exists in the field of washing and drying all-in-one machine, which has certain damage to clothes due to continuous heating at high temperature, while heat pump washing and drying machine has the advantages of low temperature drying, excellent effect and excellent energy efficiency, which is more suitable for the treatment of high-end clothes. but the price is relatively high, basically more than ten thousand.

Then what is the sanctity of the "molecular sieve low temperature drying technology" of stone H1? The so-called low temperature drying of molecular sieve can be divided into two parts: "molecular sieve" and "low temperature drying".

According to official data, "molecular sieve" is a kind of aluminosilicate, which has a good physical adsorption capacity due to its hollow framework structure, which is often called "van der Waals force" in physics, and its crystal cavity has strong polarity and Coulomb field. it shows strong adsorption energy for polar molecules (such as water) and unsaturated molecules.

How does low temperature drying of molecular sieves work? Also from official data, stone H1 adopts a double-cycle air circuit design, the first is the drying air path, which quickly absorbs water from the clothes through the molecular sieve; in the reduction air path, the water is discharged from the molecular sieve, and the water absorption capacity of the molecular sieve is restored again and again, repeatedly, to achieve the drying effect of low temperature and high efficiency.

What's the advantage? Compared with the traditional condensation dryer, the low temperature drying technology of stone H1 molecular sieve has the advantage of "low temperature" and faster drying speed.

Compared with the heat pump washing and drying machine that also focuses on "low temperature" drying, the stone H1 has a smaller dominant volume and lower noise when drying, and more importantly, compared with the heat pump type, which generally sells for more than 10,000 yuan, stone H1 also has a relatively lower threshold to start.

Thanks to this advantage of "low temperature" drying, stone H1 can avoid high temperature damage to clothing fibers and colors, away from the troubles of shrinkage, discoloration and thinning, and brings a unique drying experience of wool silk.

Of course, for us consumers, this boring working principle is not very concerned, what really determines whether consumers can take out their wallets or not depends on the effect.

Next, CTOnews.com will bring a comprehensive evaluation experience for this product, along with a closer look at whether Stone Technology's first all-in-one washing and drying machine allows you to reach for your wallet willingly.

First, the design of stone molecular sieve washing and drying machine H1 uses the traditional integrated washing and drying design, color matching provides space ash and glacier white two options, CTOnews.com gets the space ash version.

The color matching as a whole is silver gray color matching, the shape is relatively simple and atmospheric, and can be naturally integrated into the environment of different home decoration styles.

CTOnews.com also aims at different styles of home decoration environment for matching shooting.

For example, in the embedded installation of light-colored home decoration, the gray design of the stone molecular sieve washing and drying machine H1 is not obtrusive in a large number of white homes, with deep roller glass doors and integrated design control panels. on the contrary, it makes the whole home environment more scientific and technological tide flu.

Embedded installation in dark home decoration environment, CTOnews.com chose free-placement installation.

It can be seen that in the dark walls and furniture, the stone molecular sieve washing and drying machine H1 has also achieved visual "fusion" and is very "friendly" to home furnishings of different styles and colors.

As a result of the integrated washing and drying design, Stone H1 also has a smaller floor area, whether on the balcony or the bathroom is not a problem, after all, a little less "shared area" is to save a lot of money.

Free placement installation next let's take a look at the detailed design of Stone H1, starting from the top.

Stone H1 uses a pure black mirror control panel design, with a light gold surround, with a kind of smartphone breath screen aesthetic design.

On the left side of the panel is the logo of the stone, and the bottom is designed with a handle, which is filled with detergent and softener.

Detergent storage box capacity is detergent 580ml and softener 420ml, official laboratory data, two-day frequency, about a month of use, while you can also turn on or off the automatic delivery function through the "control panel" on the left.

In addition, the precise delivery of H1 can be accurate to 1ml to achieve a more accurate scientific proportion of detergents.

On the right is the color LED control screen, which you can operate directly through the touch screen above the washing machine, such as choosing different laundry modes, and so on.

In the course of work, this screen will show the working status, including washing mode, remaining time, washing stain mode, and so on.

Coming to the middle of H1, the huge black glass door is full of texture, with a slightly raised part surrounded by gold in the upper right corner, with the faint word "designed by roborock" printed on it, which is also the area where the glass door is opened.

On both sides of the glass door are printed 10-year DD direct drive motor warranty and level 1 energy consumption labels.

As the first stone washing and drying all-in-one machine, H1 is also "taken for granted" equipped with DD direct-drive frequency conversion motor.

Public data show that the DD direct drive frequency conversion motor uses magnetic levitation direct drive. Compared with the traditional belt motor, the DD direct drive frequency conversion motor acts directly on the inner cylinder and drives the washing device directly with the motor, so that the efficiency of the motor is 2 to 3 times higher than that of the ordinary washing machine.

In addition, because there is no belt and pulley and other components, DD direct drive variable frequency motor can further reduce friction and vibration, relatively less noise, less vibration, high energy efficiency, long life and a series of advantages.

DD motors in the industry are basically guaranteed for 10 years.

Open the glass door and you can see the inside of the drum.

The measured results show that the diameter of the clothing mouth of stone H1 is 300mm, and the diameter in the barrel is 510mm. It has a large volume of 72L cylinder and supports large capacity of 12kg washing and 7kg drying.

In the internal test on the upper right of the drum, there is also an intelligent induction downlight. While the washing machine is running, touch the program button on the screen and the downlight will light up automatically.

Further down, the lower right side of the fuselage is a filter cover, which can be ejected down by pressing, which is used to clean the internal drainage pump.

2. Measurement of basic cleaning capacity according to official data, the large space of stone H172L cylinder can clean 5 sets of four-piece sets at one time, or 5 down jackets, or 60 shirts, or 60 T-shirts, or 20 pairs of jeans.

12kg washing capacity in the industry as a whole also belongs to the "large capacity" range.

CTOnews.com did a simple test, starting with a thick coat, a thick suit, four large bath towels, two small towels, a large scarf, a sweater shirt and jeans each.

When these laundry items are placed on top of the washing machine, the space occupied is shown in the following picture:

The large "belly" of stone H1 easily accepts these clothes, and there is no pressure in the washing process.

In terms of basic cleaning ability testing, CTOnews.com has also done a simple test.

In order to be more in line with consumers' daily laundry habits, we choose to clean and dry white shirts, Terry bath towels, white cotton jackets, plush coats, plush toys and other clothes at the same time, and choose the "standard" laundry mode. The drying mode is "extra-dry", the washing times is 2 times, the washing temperature is 30 °C, and the whole laundry process is 2 hours and 53 minutes.

First of all, there is a representative white shirt. before washing, we simulate the daily dirt. The left shoulder of the white shirt is sprinkled with oily sauce, the right part is sprinkled with Coca-Cola, and the neckline also has visible stains. The above stains are dried before washing.

Comparison before and after washing:

Oil stains: before and after washing

Coke stains: before and after washing

Collar stains: before and after washing, as shown in the picture, a large area of obvious oil stains on the left side has completely disappeared after a period of washing, leaving no trace of "has been here", and the effect is very satisfactory. and the white shirt that yellowed after passing through for a period of time became white after washing.

The cola stains deliberately sprinkled on the right side have also disappeared, and after "standard" washing, the stains on the shirt collar and the inside of the collar have disappeared, and the shirt has become as white as new.

This proves that these daily stains are not a big problem for stone H1.

Next, let's briefly test the drying effect of stone H1.

H1 provides three drying modes including micro-drying, ordinary drying and ultra-drying, while CTOnews.com chooses ultra-drying mode.

According to the official description, the drying mode can completely dry the clothes, which takes the longest and driest, and is used for off-season storage, reducing wrinkles, moisture and mildew.

As shown in the following figure GIF, the dried bath towel is completely dry, soft and fluffy, and the clothing fiber has been fully stretched.

Before the test, CTOnews.com also measured the height of the bath towels folded, and then compared it with the height folded after drying.

As can be seen from the following figure, the height before washing is about 7-8CM, while the height after drying is about 8-9CM, which proves that the bath towel is completely dry and fluffy.

High contrast: the plush coat before washing and after drying is also dried in ultra-dry mode, and the outer layer of imitation rabbit wool has become fluffy and supple.

CTOnews.com also tested the height of the plush coat before and after washing and drying. by comparing the figure, we can see that the height is basically the same before and after the test, both around 8CM.

High contrast: CTOnews.com tested the weight of the plush coat before and after washing and drying. As shown in the figure, the weight before the test is 457g, but after drying, the weight is 456g, which is 1g lighter than that before washing, which can also prove the good drying effect of stone H1.

Weight comparison: the molecular sieve low temperature drying technology of stone H1 is really useful for friends who are often in the rainy season before washing and after drying.

Of course, for any all-in-one washing and drying machine, drying clothes is a matter of duty, but how to do "drying" better depends on your own ability.

Thanks to the same advantage of low temperature drying (50 ℃ ±3 °C) as the heat pump, and RR washing and drying algorithm, Stone H1 brings the ability of "wool silk drying", and has obtained the double certification of wool silk washing and drying in Zhongjiayuan, which is not easy to deform, shrink and fade after washing.

Next, CTOnews.com will actually test this feature to see how it works.

Third, the test of wool silk is well known, wool clothing often has the problem of washing and shrinking, and many wool clothes can instantly change from "L code" to "S size" as long as they go through water, not to mention the high temperature during drying. It can also cause irreversible damage to wool.

The "wool washing and drying" of stone H1 has the advantages of protecting clothes and reducing shrinkage and pilling. In order to verify the above effect, before and after the test, CTOnews.com measured the weight, thickness, chest circumference and hem length of the clothes to verify whether there was a shrinking problem.

CTOnews.com chose a 100% pure wool cardigan as the test, choose wool washing and drying mode, the temperature is set to room temperature, rinsing times is 1, ultra-dry mode.

The expected time of washing and drying is 2 hours and 56 minutes, of which washing is about 40 minutes and drying is about 2 hours.

As shown in the following picture, the chest circumference of the cardigan is about 44.7CM before washing and about 44.5CM after washing and drying. considering the test error (the cardigan itself has elasticity and extensibility), the difference in 0.2CM is almost negligible.

Chest circumference comparison: the length of hem before washing and drying (left) and after (right) hem test is 39.8CM, and the length after test is 39.6CM, which also has the error of 0.2CM.

Hem comparison: before washing and drying (left) and after drying (right), however, the height of the cardigan folded after drying increases a little, which proves that the wool fiber has been fully stretched after drying.

High contrast: before washing and drying (left) and after (right), because the folding method each time can not guarantee 100% consistency, so the above test can only be used as a simple reference, which simply proves that after the washing and drying of stone H1, this cardigan has no exaggerated shrinkage problem.

Weight comparison: the weight before and after washing and drying (left) and after (right) test also verifies the above statement. Before the test, the weight is 520g, after the test, the weight is 517g, and the error of only 3G can also be ignored. This proves that stone H1 does have excellent wool washing and drying ability, although there is no guarantee that it will not shrink, but at least the degree of "shrinkage" is negligible.

Stone H1 is mainly washed and baked at a low temperature, so CTOnews.com is also tested simply by thermal imaging.

It should be emphasized that because it is impossible to accurately measure the specific temperature in the barrel during drying, CTOnews.com chose to measure the temperature outside the barrel, and after the drying work is completed, open the cover of the barrel as soon as possible to measure the temperature of clothing.

Temperature in wool washing and drying mode: the washing and drying work starts for 1 hour, 2 hours, and the washing ends as shown above. In the wool drying work, the highest temperature of the shell never exceeds 28.9 °C. unlike the slightly "hot" shell of other dryers, the shell of stone H1 is not even a "residual temperature", and after opening the lid, the highest temperature of the clothes is only 33 °C, and the freshly dried cardigan is fluffy and soft. The fragrance of the detergent comes to the nostrils without any moisture or dampness. it feels as if it has just been exposed to the morning sun and can be worn directly.

For comparison, in the standard washing mode (non-wool washing), the highest temperature of the H1 shell can reach about 38.8 °C, with a slight residual heat, while the highest temperature after opening the lid is 47.3 °C.

Standard drying mode temperature: washing for 1 hour, the end of washing and drying can be intuitively felt by comparison, stone H1 in wool drying mode, does have a quite good "low-temperature clothing" advantage.

In addition to wool, CTOnews.com also simply tested the washing and care ability of silk.

After washing and drying silk, this silk scarf shows the glossiness that silk products should have, and through the microlens of the mobile phone, we can see that the relatively fragile fiber structure of silk has not changed significantly before and after the test.

Silk fiber structure: before and after washing and drying (color difference is the color of different parts of the scarf) fourth, noise vibration measurement to determine whether the material of a washing machine is solid, high-end, one of the most intuitive way is the noise generated at work.

Because there is no compressor, and the use of direct-drive frequency conversion DD motor, so in theory, stone H1 has a great advantage in this part.

First of all, let's talk about the author's subjective feelings. In the process of laundry, the only "noise" produced by stone H1 is the rolling of clothes and the sound of water flow, including the sound of motor operation is almost inaudible, and the mute performance is very excellent.

CTOnews.com tested the noise of H1 by decibel meter.

Under the noise environment of indoor 50dB, close to the cabin door of H1 washing, the noise is only 52dB, which is equivalent to the sound of breeze blowing through the ear, which is basically negligible.

The noise when the stone H1 is dehydrated is not very loud, and the noise is only about 57.6dB when the motor is swinging at 1400 rpm. If someone around you is talking to you, or brushing a short video on your cell phone, it can dilute the noise caused by the dehydration of stone H1.

In addition to the noise during drying, the vibration of H1 dehydration during high-speed rotation is also very small. When the author puts a glass of water above the fuselage, we can see that the water surface fluctuates slightly, while the water cup is motionless.

Vibration during drying, the working noise of stone H1 still exists, which is mainly caused by the wind howling sound caused by the fan, which is measured as 59dB and still does not exceed 60dB.

When drying the noise during the day, the sound is not too obvious and can basically be offset by the surrounding ambient sound, but if it is quiet at night, the drying sound is still relatively obvious, somewhat similar to the sound of the first and second gear of the living room fan.

If you put it on the balcony and the bedroom is closed at night, you can hardly hear it.

During drying, noise 5, App and other experience stone H1 provide 25 intelligent washing programs that can automatically adjust washing time, water level and washing speed according to clothing weight and material.

The panel includes 12 washing procedures including standard, fast, anti-bacterial mite, wool, air washing, APP custom, home textile, down, silk, bleaching + stripping, single dehydration, cylinder self-cleaning.

You can operate directly through the touch screen above the washing machine, such as choosing different laundry modes, and so on. In the course of work, this screen will show the working status, including washing mode, remaining time, and so on.

The overall operation is relatively simple, basically do not need to check the instructions to start the operation, the learning cost is low.

Download Stone App, bind the device, you will see the washing machine more detailed function menu, as well as operation options, you can also remotely control, check the working status and so on.

In App, you can also choose cotton and linen, baby, anti-allergy, exercise, night, new clothes, shirts, chemical fiber, underwear, strong, gentle, changing seasons, warm clothes and so on.

As mentioned above, the process of both tests takes about 2 hours, isn't it a bit long? In fact, this also includes the drying time, and through the RR washing algorithm, the equipment will judge the cleaning time according to the weight of the clothing.

You can also choose "fast" washing mode, which can be finished in one hour at the earliest. You can also choose a variety of different laundry modes, such as rapid washing, removing bacteria and mites, home textiles, down, babies, etc., or single dehydration, bleaching + stripping, or separate washing, drying, and so on.

In other aspects of experience, stone H1 also supports multi-dimensional sterilization of the whole machine, including hydrolyzed silver ion + pasteurization + pipe / inner cylinder drying + antibacterial door mat + door spray to achieve comprehensive bacteriostatic washing.

In the "health" program, you can also choose to remove bacterial mites, anti-allergy, air washing, 90 ℃ cylinder self-cleaning, more suitable for sensitive skin people.

Taking the model of removing bacteria and mites as an example, stone H1 will remove mites by washing at a water temperature of 60 ℃. The cylinder self-cleaning mode can heat the washing water temperature in the cylinder to 60 to 90 ℃ (default 60 ℃) and use the high-speed operation of the washing machine to drive the flow of water to rotate 360 °to wash away the dirt.

Stone H1 also supports a floss filter self-cleaning system, which is an advantage that traditional condensing washing and drying machines do not have, and there is no need to manually clean the filter every week like a heat pump dryer.

Stone floss filter self-cleaning system is completely "self-cleaning", saving manual trouble, this part of the time reason, will not be demonstrated.

Power-off memory function is also very good, in the process of testing, I really encountered a power outage, but soon after the resumption of the call, stone H1 does not need any operation, still continue the previous program mode to work.

Write in the end: in the author's view, to evaluate the stone molecular sieve washing and drying machine H1 more strictly, then it must be compared with the condensing and heat pump machines on the market.

Compared with the condensing all-in-one washing and drying machine with the same price, the drying effect of stone H1 is better, the efficiency is higher, and the ability of protecting clothes at low temperature is stronger, and the effect is comparable to that of heat pump all-in-one machine. Compared with the higher-priced heat pump all-in-one machine, Stone H1 can achieve smaller size and lower threshold for purchase with the same efficiency.

Therefore, the molecular sieve low temperature drying technology of stone H1 is not to replace the condensation type or heat pump type, but provides a better choice between the two.

The release of Stone H1 dare not be said to be a revolution in the all-in-one machine market, but it at least gives consumers a third choice, and no matter in terms of experience and drying effect, or the pricing that consumers are most concerned about, next it is a difficult choice to bypass.

Obviously, Stone's entry into the all-in-one machine market is not a hasty move, but with its long-standing observation and thinking in the field of intelligent technology.

Back to the product itself, stone H1 design maintains the stone science and technology has always been minimalist, generous aesthetic level, comprehensive washing and drying function experience, especially obvious advantages in low temperature drying. If you have a certain pursuit of high-end protective clothing, if you are unable to use the expensive heat pump washing and drying machine, then you might as well take a look at this stone H1. I believe it will bring you "good value for money".
