I. Preface: Decrypting IH

1, the rice cooker suddenly fired, but also brought the fire "IH"

In 2015 and 16 years, shopping in Japan became a big event of the whole year. In 2015, a total of 5 million Chinese tourists visited Japan and bought nearly 80 billion yuan of goods. In 2016, these two figures increased to 6.37 million and 900 respectively. Billion.

For two years in a row, the Japanese almost bought out Japan’s electronics stores and “buy it” for the Japanese annual buzzword. The rice cooker and the toilet lid became the best-selling Japanese products.

The impact of explosive buying by the Chinese people is far-reaching. Until now, there is also a rice cooker category specifically labeled in Chinese in the Japanese kitchen appliances category in Amazon.

There are many reasons for the hot sales of daily-use products in Japan. However, there is much discussion here. However, as an inventor of rice cookers, Japan is undoubtedly profound in the accumulation of rice cooker technology.

And as more Japanese rice cookers enter China, the various selling points of Japanese rice cookers have also refreshed consumers' perceptions. What a gorgeous word such as “Southern Ironware,” “Hot Heat,” and “Amako Kettle” became consumers The sought after object.

There are 5 IH rice cookers in the top 10 among the Riria Electric Rice cookers.

The "IH" technology, the most widely used of rice cookers in Japan, has undoubtedly become the most popular selling point for home-made rice cookers in the past two years. Today, it has become the standard for domestic rice cookers of more than 400 yuan.

It can be said that without IH, you are not a qualified high-end rice cooker.

2. What exactly is IH technology?

IH is English induction heat, electromagnetic heating, which is our common induction cooker heating technology.

↑↑↑Induction cooker working principle diagram

The basic principle of this technology is Faraday’s electromagnetic induction, which uses alternating current to convert into a magnetic field. After the magnetic field touches the pot, a turbulent effect will be generated inside the pot, and the eddy current will drive the electronic movement inside the pot to make the pot directly generate heat.

In simple terms, electrical energy is converted into a magnetic field. The magnetic field then “frictions” heat with the iron pan (liner) to heat without using an open flame.

For this reason, pots using electromagnetic heating must be magnetic (usually iron, gold, copper material), which is why the general aluminum pan can not be used in the induction cooker.

↑↑↑ This is also the reason why IH rice cookers generally emphasize the "iron kettle" (iron liner).

It can be seen that IH is essentially a heating technique. How did the original rice cooker heat before IH? IH replaced it by hacking it?

Traditional rice cookers use heating plates to heat them. Simply put, the heating plate is a high-power resistor. When the current passes through the resistor, it will generate heat. Then the heating plate transfers heat to the bottom of the inner pot for heating.

The heating principle of traditional rice cookers is similar to that of electric ceramic stoves.

The IH has several advantages over the traditional heating plate.

3, the characteristics of IH

1IH Benefits

Traditional rice cooker hot plate heating, heat from the bottom of the hot plate to the top of the rice, there is a conductive process, it is prone to the bottom of the water has been dried, the top is still wet uneven heating.

After IH is used, the magnetic inner liner (generally iron or alloy) will heat the entire liner at the same time when cooking, especially the inner wall of the rice will also generate heat, so that the rice is more evenly heated.

↑↑↑IH heating can basically understand this

This is why IH rice cookers are usually "thick cauldrons" (ie, thicker iron liners). The thicker the bladder, the more uniform the heat in each direction when it is heated.

In theory, the more evenly heated rice, rice grains absorb moisture more completely, the taste is more consistent, and the bottom is less likely to boil.

However, compared to a simple heating plate, the more complex IH heating method brings more complicated hardware, and it also brings several "old problems" of the induction cooker.

The bad point of 2IH

1) In the same way as induction cookers, rice cookers using IH technology also require fans to actively fan the heat.

The reason is that in the heating process, each high-power semiconductor element and the reel inside the induction cooker is heating, and a part of the interior of the interior of the induction cooker also conducts heat to the inside of the interior.

2) With a fan, there is bound to be more noise. Remember the sound of the induction cooker?

3) In the same way as induction cookers, electromagnetic radiation is produced within 20 to 40 centimeters of the machine, but radiation beyond this distance decays to zero, with little impact.

In general, the more uniform heating methods brought about by the IH technology, although inheriting some of the old problems of the induction cooker, what are these minor problems in order to cook the rice better?

Demi IH Rice Cooker 4L

So what exactly does the Mi-IH rice cooker 4L perform in the end, can it fully exploit the advantages of IH and bring about a better cooking experience?

Second, the appearance: to meet 8 home! Minimal design

The author is in the hands of the rice IH rice cooker 4L version

Get rid of all accessories except the manual

↑↑↑ The front of the camera is very simple, with only one cover button

↑↑↑ The back of the camera is a status indicator

↑↑↑ The bottom of the left and right sides of the fuselage has a groove for easy lifting. The power socket is in the lower right corner of the right side of the fuselage.

↑↑↑ At the top of the fuselage is a vent and hidden light

↑↑↑ Indicators and function description stickers on the keys to help users get started

The fan port at the bottom of the fuselage, because the rice IH rice cooker uses the same IH (electromagnetic heating) technology as the induction cooker, so you must use a fan to actively fan the heat.

After opening the lid, there is a complimentary steamer, which is very practical

↑↑↑ Top seal ring, it is worth mentioning that there is a separate seal switch, gently push the switch to remove the seal ring for cleaning

Rice cooker liner, thick flame means "more thermal conductivity, heating a more uniform thicker liner", in addition to rice IH rice cooker liner is alloy material.

Mi IH Rice Cooker 4L As the name implies, it has a 4L interior volume, compared with the previous rice pressure IH rice cooker 3L version, 4L liner size is much larger.

Comparison between 4L and 3L versions

The 3L version of the inner liner can be completely put into the 4L tank and it will make a full circle

↑↑↑3L version can put up to 5 cups of rice

↑↑↑ 4L version can put up to 8 cups rice

In terms of one cup of rice per person, the 4L version can satisfy eight meals, and there are three more people than 3L.

It can be seen that the rice cooker IH rice cooker 4L continued the design style of the rice products, and the pure white body has a richer sense of design compared to the market where most of the selling points are affixed to the face.

A Japanese brand rice cooker that sells for 16,000 yuan on electricity suppliers

Perhaps considering the minimalist style, the rice cooker IH Rice Cooker did not design rice cookers more commonly referred to the handle, but instead to the bottom of the handle groove. Although slightly inconvenient, it is more beautiful and also shows that the sense of design is more important for the rice cooker IH.

The minimalist design with hidden lights and only three buttons is more in keeping with the modern style of home decoration. Whether it's lost in the corner or in the living room, the non-attributed Mi I rice cooker can be integrated into the environment.

Another rice IH rice cooker is not a stand, 4L version of the big liner is very practical, compared with 3L more than 3 cups of rice, to meet more people's appetite.

Third, the comparison test: 7 blocks of 6 rice won the IH blindly

The author chose an electricity supplier's price of 299 yuan, without the IH function of Supor rice cookers, and rice IH rice cooker do comparative test.

Why not use rice cookers with IH function at the same price? This is not the author's eccentricity but considers three reasons:

The first is that the IH function is a new selling point that has not yet been popularized. Many consumers do not understand the actual effectiveness of IH and it is necessary to show readers the effect of IH.

The second is the comparison of the same IH rice cooker, which is prone to fall into the metaphysical field of "this rice bowl has a better taste". The reader can not feel empathy.

The third reason is that the final reason for determining the taste of rice is the quality of rice. The more powerful rice cookers are just the icing on the cake.

And really talking about the best way to cook rice, the traditional firewood is undoubtedly the best, which is why many rice cookers hit the selling point of “wood fired rice”. Even Japan, which has the most advanced rice cooker technology, is still trying its best to restore the taste of the "pot of soil." This is a kind of return to nature.

The best firewood meal

1, cooking noise comparison

Because IH technology requires fans to dissipate heat, there will be fan noise and it will not be as quiet as traditional rice cookers. Will the cooking noise be so great?

While cooking, near the Mi IH rice cooker, a slight fan sound can be heard at the bottom, but the sound is not loud.

Detox rice IH rice cooker cooking noise

After testing, the cooking noise of Supor rice cookers was around 42-48 decibels, and the noise of Mijia IH rice cookers was around 45-52 decibels.

The noise of the rice cooker IH rice cooker is slightly higher, but the difference is very small, and it belongs to the normal level of speech (40-60 points). It seems that the IH rice cooker's cooling noise control is good.

2, comparison of cooking effect

↑↑↑Suppor rice cooker rice cooking effect, the middle of the rice is prominently raised

Supor cooker rice surface detail

The reason why the rice bulge occurs is because the traditional rice cooker is heated by the bottom heating plate, and there is a process of heat from the bottom to the top. After the water has stopped heating at the bottom, the top (especially the middle) of the rice has not yet been fully heated and is still caused by excess moisture.

Rice cooker rice cooker cooking effect

Most of the surface of sticky rice is relatively flat, with no noticeable protrusions and depressions

Is the rice surface of the demi rice IH rice cooker more smooth?

Because the principle of IH heating causes the entire liner to heat up, the rice can simultaneously absorb the heat emitted from the bottom and the periphery.

The larger heated area allows the rice to receive more uniform heat during cooking, rolling more fully when boiling, and more uniform when the water evaporates. IH heating ensures more consistent heat absorption per grain of rice.

Because of the more uniform heating method, the rice cooker IH rice cooker can show a more even surface of rice.

3, rice taste contrast

The rice tested by comparison was an unnamed bulk rice purchased by the author from a supermarket. It was 7.6 yuan a pound.

The cooking mode of the Supor rice cooker is a boiled bomb. The cooking mode of the rice cooker IH is fine cooking. The two household appliances also take about one hour to complete the task.

↑↑↑ supermarket supermarket

The rice cooked in a Supor rice cooker on the right side of the plate

The rice on the left side of this plate is cooked by rice cooker IH rice cooker

Basically, the details of the rice can not tell the difference, directly into the tasting stage, the rice is full of rims, and the colleague A and the colleague B conduct the blind eating test.

Colleague A's comment: The left side of the block is more delicate and more fragrant than the right one. The left side and the left side (rice) are delicious.

Colleague B's comment: chewing... The rice taste on the left side is stronger and the right side is a little softer (pointing at the rice rice). This rice is better.

The two blind-lipped colleagues agreed that the rice in the rice cooker rice cooker was better. At the beginning, the author had some doubts about the rice cooker. The rice taste gap was so big?

After eating two large mouthfuls of rice, the author really understands the difference between the two, which is specifically defined from inside and outside the rice layer:

The outer layer of rice: The outermost layer of rice, the taste of the rice cooked in the two home-made rice cookers was not very different and basically the same.

Rice inner layer: Gap In the inner layer of rice, the taste of rice inside and outside the rice is the same, the same chewy flavor.

The taste of Supor rice varies greatly both inside and outside, and the closer it is to the interior, the more sticky the rice taste is, that is, the greater the water content. Because of the reason that it is not fully cooked, the inner layer of fragrance is not as good as the outer layer of rice.

In other words, the traditional way of heating the rice cooker does not allow the inner layer of rice to be heated sufficiently, which results in the inner layer of rice being unable to fully “strengthen its strength”.

The IH technology solves this problem. This is the reason why IH technology can make rice better, and it can become the standard for rice cookers in Japan, and it can quickly spread in the country.

Fourth, APP experience: With it all kinds of rice are known!

Demi IH Rice Cooker is still connected with Mijia App, and there is no difference between the process and the ordinary Mijia product WIFI connection process.

The glutinous rice cooker rice cooker homepage provides 9 kinds of main rice cooker applications, and also provides more recipes for viewing. It is also very convenient for recipes.

↑↑↑ After entering the rice cooking mode, the APP can intelligently detect the altitude, adjust the insulation, rice selection and taste curve

Rice varieties provide a lot of different rice, and can scan the bar code of rice bags to automatically judge rice varieties. According to different rice varieties, rice cookers can make different heating strategies.

At the same time you can customize the taste of rice, with three levels of soft, medium and hard.

When cooking, the app will automatically show the cooking process

After you have cooked your meal, APP will send notifications in a timely manner

It can be said that the intelligent experience of the rice cooker IH Rice Cooker continues the consistent high level of Mijia products, rich heating methods, convenient recipes, and customizable rice softness.

It can even scan rice packaging to detect rice varieties, and customize different heating strategies depending on the type. From the beginning of the cooking to the cooking notification, the APP experience of the Mi I rice cooker is very pleasant.

V. Conclusion: IH Blessed High-Volume Rice Appliances

Appearance: The rice cooker IH rice cooker 4L continues the 3L version of the design, with only 3 button minimalist design, pure white appearance and large capacity liner, taking into account beauty and practicality.

Cooking: After testing, it can be seen that the IH function is not used by businesses to fool consumers, but it can really change the heating method of the rice cooker to make the rice fully heated and maintain the consistency of rice taste.

Smart APP experience: Maintained the consistent high degree of customization, ease of operation, and intelligent and considerate features of the home appliance. In particular, different types of rice can be customized for different cooking methods. This is very convenient.

In general, excellent design, practical IH function, large-capacity tank, mainstream 599 yuan price, all show the characteristics of Mi-IH rice cooker approachable, Mi-IH rice cooker 4L version still continues the Mi-style cost-effective.

Although the 3L version of the price of 399 yuan butcher did not do, but in the price of 599 yuan, with the above advantages, Mi Jia IH rice cooker 4L is undoubtedly the same price of rice cookers in a very competitive product.

However, Japanese IH technology is only one of the most basic and most popular technologies for Japanese rice cookers. Currently, major Japanese brands are exploring different directions of rice cooker technology.

↑↑↑ Sharp's automatic rice cooker, yes, you did not miss it, just like a washing machine

For example, like the hand-built "Southern ironware" liner, Panasonic's variable pressure heating, Tiger brand to simulate the firewood soil cooker "pot kettle" liner.

The domestic rice cooker has only just kept pace with the next door, and the future of rice cookers is far from the end.
