In recent times several friends asked me to buy a refrigerator, and after talking to them, found that they are mainly divided into two factions: large families and small households, the difference between these two types of needs for the refrigerator is actually still quite large, which also allows them to hesitate in the choice of many products. So I decided to give you a small recommendation here, the brand, is my personal favorite Hitachi, the models are large refrigerator flagship Hitachi refrigerator R-ZXC750KC and small flagship pop Hitachi refrigerator R-XG420KC, in the article as much as possible to show the two kinds of refrigerators their respective advantages and characteristics, after reading this, I believe that you will be able to do a number of their own choices and needs.
Why recommend Hitachi
There are three main reasons to recommend Hitachi:
Big brand: Hitachi was founded in 1910, and is now a proper century-old company, as a company that started as an electric motor, Hitachi has continued to develop its own business in 112 years. As a company that started out as a motor, Hitachi has continued to develop its business over the past 112 years, and its business now includes a wide range of fields such as energy, railroads, health management, and medical care. It has developed Japan's first DC electric locomotive, the first digital computer, and the Shinkansen traffic control system, which is definitely the leading technology in the industry.

I have used: And this is not a short period of time with the use of my family's first refrigerator is Hitachi, that is still in the 90s, Hitachi as the reform and opening up after the earliest into China's one of the home appliance enterprises in a long time have been favored by the domestic consumers, my home, the old Hitachi refrigerator. The old Hitachi refrigerator in my home, the impression of smooth operation for 15 years, until 2003 when it was replaced, and the reason for the replacement is not a quality problem, but the capacity really can not keep up. It is because of the outstanding product quality, so that I have been very trusting of this brand. PS: My family is now using the Hitachi refrigerator, because individuals have a kind of obsessive pursuit of food storage you, and Hitachi's products in this meticulous classification to do a particularly good job, with a very comfortable.

Black technology: A hundred years of accumulation brings not only brand awareness, but also a deep accumulation of technology and technological innovation, Hitachi's many home appliances have their own unique technical advantages. For example, Hitachi's famous vacuum ice temperature technology for refrigerators is a typical example of this, utilizing special design ideas and subtle small parts to form a special chamber with excellent freshness, and achieve good freshness, which is the result of Hitachi's accumulated years of technology.
Classification of refrigerators
Before we get into the formal content, let's do a little science and talk about the eight classifications of refrigerators.
The two refrigerators I'm talking about today, the Hitachi R-ZXC750KC and the R-XG420KC, are both standard Japanese multi-door refrigerators, but they're different from traditional Japanese multi-door refrigerators in that, while they still have detailed zoning and a wide variety of specialty spaces, they have their own trade-offs in size and capacity. We'll talk about that later.
Refrigerator Appearance Comparison
First, let's look at the appearance of these two refrigerators. The same is Hitachi's products, listed on the time is about the same, so these two refrigerators still have a lot of the same things, such as the same crystal mirror glass as the refrigerator panel material, this material has a crystal clear feeling, but also like a mirror reflecting the surrounding scenery, and stain-resistant wear and tear easy to take care of the last two years is very much favored by the home appliance manufacturers.

At the same time, these two refrigerators are used in the touch operation panel, that is, all the buttons are concentrated in the same part of the refrigerator panel, it is convenient for us to adjust all the settings of the refrigerator, the touch buttons are also more comfortable to use, avoiding the shortcomings of the entity buttons easy to damage.

And the main difference between the two appearance is the volume, R-ZXC750KC Hitachi refrigerator size is relatively large, up to 880 * 738 * 1833mm, properly large, unless your home kitchen is particularly large, I still recommend that you put it in the dining room, but do not have to worry about the dining room in the dining room will appear to be out of the ordinary, after all, the R-ZXC750KC R-ZXC750KC. ZXC750KC's high quality is still guaranteed to complement any home style. This size of refrigerator is more suitable for large families, and the diversified functions are also very good to ensure that a variety of dishes can get the right storage.

And R-XG420KC size is only 600 * 664 * 1798mm, width and depth than the Hitachi R-ZXC750KC is much smaller, is considered a slim type of beauty. This size of the refrigerator placement is a little more casual, as long as the kitchen space is not too shabby, generally can be put down, cooking time to get ingredients is also more convenient. If you have a family of about three people, then it is definitely one of the most suitable choice, occupies a small area, enough space, complete function.

Refrigerator Volume Comparison
The volume is different, the capacity is naturally different. Hitachi R-ZXC750KC refrigerator capacity of 735L, the standard pot-bellied man a, relatively more suitable for 4 ~ 5 people of the extended family use, whether it is the elders love to eat fresh vegetables or children like cold drinks ice cream, can be easily loaded, a hoard of about a week's worth of ingredients are a breeze. The Hitachi R-XG420KC has a capacity of about 401L, a more moderate size is more suitable for 2~3 person family use, able to store 3~4 days of fresh vegetables needed, the specific choice of which one, depends on your own needs.
Hitachi R-ZXC750KC refrigerator capacity of 735L
By the way, compared to other brands of the same size, Hitachi refrigerator volume is really considered larger, such as Rongsheng BCD-221WD16NY refrigerator, size 545x607x1776mm, it is a little smaller than Hitachi R-XG420KC refrigerator, but the The volume is only 221L, almost half that of the R-XG420KC refrigerator, and a big part of the reason is that the walls are thicker and take up too much storage space. Hitachi refrigerators are able to achieve a small volume and large capacity, thanks in large part to the superiority of the unique VIP vacuum insulation material, which takes advantage of the characteristics of the vacuum insulation to ensure good thermal insulation, while being a little bit lighter and thinner as possible, so that the volume is maximized as much as possible.
Freezer compartment
The layout of the freezer compartments of the Hitachi R-ZXC750KC refrigerator and Hitachi R-XG420KC is basically exactly the same, except that the sizes of the spaces are different, and they are both made up of an open storage area + a vacuum ice temperature area + a water storage box, and the reason why there's a water storage box is because both refrigerators have an automatic ice-making function. The reason why there is a water storage box is because both refrigerators have the automatic ice-making function, and the water here is for the automatic ice-making reserve. The vacuum ice temperature is the preservation of technology, we will talk later.
Hitachi refrigerator freezer
Hitachi R-ZXC750KC refrigerator freezer volume of 368L, Hitachi R-XG420KC refrigerator freezer 241L, the contrast is still relatively obvious. Hitachi R-ZXC750KC refrigerator freezer highlights a large, even and Hitachi R-XG420KC refrigerator total volume (401L) is not too much difference, after all, the choice of Hitachi R-ZXC750KC refrigerator certainly have their own large storage needs, and Hitachi R-XG420KC refrigerator pursuit of small and exquisite life is still very different.
Freezer
Similarly, the freezer compartments of the Hitachi R-ZXC750KC refrigerator and Hitachi R-XG420KC refrigerator are similar, consisting of a large freezer compartment, a small freezer compartment, and an automatic ice compartment, and the large freezer compartment is a multilayer structure design, which allows you to store different ingredients in different categories. For example, poultry in a layer, livestock in a layer, frozen in a layer and so on.

And the small freezer has a special design of quick-freezing, can be frozen in a short period of time, as much as possible to ensure the freshness and nutrition. The automatic ice chamber is simpler, preparing ice cubes mainly in it for easy access at any time.
The total freezer volume of the Hitachi R-ZXC750KC refrigerator is 212L, while the freezer volume of the Hitachi R-XG420KC refrigerator is 112L, which is basically double the difference.
Vegetable compartment
Both Hitachi R-ZXC750KC and R-XG420KC refrigerators have separate vegetable and fruit compartments, which has been a trend in refrigerator development in recent years. In the past, we are accustomed to putting fruits and vegetables in the freezer for storage, but both leftovers and fresh fruits and vegetables, making the use of a very inconvenient, and often make the inside dirty, so the specialized fruits and vegetables storage room appeared.
Hitachi refrigerator dormant fruits and vegetables room
These two refrigerator fruits and vegetables room are located in the bottom of the refrigerator, the same multi-layer design, can be used to store different sizes of fruits and vegetables, push-pull design also makes taking a lot easier. The Hitachi R-ZXC750KC refrigerator's fruit and vegetable compartment has a capacity of 137L, which is why I said earlier that it would be able to store about a week's worth of dishes (paired with the freezer section and external dishes together).
The Hitachi R-XG420KC refrigerator's is only about 75L, which is fine for seven or eight meals (two to three dishes per meal) with the vegetables stored outside. (If your family eats four or five dishes a meal, forget I said that.)
Special Features Comparison:
When talking about the ability of Hitachi refrigerator freshness, there are three terms can not be bypassed, the vacuum ice temperature preservation, platinum catalyst preservation of freshness, rapid freezing, these three technologies are basically the Hitachi refrigerator series is the most representative, and also the most famous practical preservation of freshness technology. As the two main Hitachi refrigerator products, R-ZXC750KC and R-XG420KC of course, are equipped with these three practical design, which makes it easier for me to introduce.
Vacuum Ice Temperature Preservation
The vacuum mentioned here is not really a vacuum, but rather, it draws air from the confined space with the help of the refrigerator's built-in vacuum pump, which reduces the air pressure in the space to 0.8 standard values. In order to maintain this air pressure standard to avoid air leakage, the entire vacuum ice temperature preservation room storage space are specially designed, inside and outside the airtight isolation done very well. After the air pressure is reduced and the air inside and outside is isolated, the air flow in the space tends to be static, and the ingredients can be better preserved in this environment, and the loss of nutrients is greatly slowed down.

sealed low-pressure space + low-temperature environment, is the secret of the vacuum ice temperature preservation technology, from the market feedback, this technology is indeed able to save fresh food, such as delicate fruits, cream cake, salmon, raw fish, etc., to extend the shelf life of them, and the next time you eat the texture can also get better! Preservation.

Platinum catalyst
Before we get to the technology, let's talk about what a platinum catalyst is. This factor can effectively capture free ethylene and odor molecules in the air, and then decompose them into water and carbon dioxide. Ethylene is a gas naturally emitted by fruits and vegetables, which has the effect of ripening, and a little inattention can lead to fruit rotting and spoilage.

Platinum catalyst's role is to similar components of the rapid decomposition of the decomposition of water and carbon dioxide there is a benefit: high humidity environment is easier to preserve fruits and vegetables, does not lead to dried out and tasteless, while the concentration of carbon dioxide is high can also slow down the respiratory movement of fruits and vegetables, so that they enter a kind of dormancy, to avoid rapid oxidation, to extend the food shelf life, and to prevent the development of the environment, to ensure that the environment is safe and healthy. Rapid oxidation, extending the shelf life of food. The Hitachi refrigerator has a specialized platinum catalyst generator inside, which constantly produces this special factor, which is safe and harmless, and the preservation effect is also quite good.
Rapid Freezing
Before we talk about rapid freezing, let's first talk about why all manufacturers are pursuing rapid freezing. In fact, the reason is very simple: the faster the freezing speed, the more effective in retaining the moisture, nutrition and flavor of the food itself. Traditional freezing methods, food is from the outside and inside the beginning of the ice crystallization, in the exterior because of the low temperature after the production of large ice crystal particles, these ice crystals will continue to spread inward, the larger ice crystal particles will pierce the cell wall of the food cells, so that the rapid loss of juice, and continue to squeeze inward, so that the food becomes dry, and at the same time a large number of nutrients are lost.

And Hitachi's rapid freezing technology, in addition to the use of a powerful refrigeration system, but also with the use of a large aluminum plate, with the help of metal products with good thermal conductivity to quickly absorb the heat of the food itself, so that the food quickly through the easy to generate large ice crystal particles of -1 ~ -5 degrees Celsius, so that the food inside the formation of the formation will not squeeze the cell of small ice crystal particles, so as to avoid moisture and nutrients loss. This prevents the loss of moisture and nutrients.
All three of these features are present in both the R-ZXC750KC and R-XG420KC refrigerators, right down to the location, with the only difference being the size of the three special spaces. This is why I recommend these two refrigerators, after all, the most basic function of the refrigerator is to preserve freshness, with these three major technologies Hitachi R-XG420KC refrigerator and Hitachi R-ZXC750KC refrigerator refrigerator, can definitely meet your needs.
In addition, the Hitachi R-XG420KC refrigerator and Hitachi R-ZXC750KC refrigerator are equipped with automatic ice-making function, and the overall design is similar.
Hitachi Refrigerator Ice Maker
When you need to use it, pour pure drinking water into the water storage box in the freezer area, and the internal pipeline will send the water flow to the ice maker on the inside of the refrigerator door, and use the low temperature to prepare pure edible ice, and then store it to be used at any time when you need it. At the same time, in order to avoid bacteria after a long time of use, this set of ice equipment also has an automatic cleaning function, the use of high-speed water flow on the internal pipeline flushing, take away all the mucus and bacteria, to keep the ice-making system clean and hygienic.

WIFI Remote Control Design: In this era of Internet of Everything, the refrigerator is naturally no exception. With the help of specially developed intelligent APP, we can use our cell phone to perform a series of operations on the refrigerator, understand all the current status, and remotely set various functions. If you forget to close the refrigerator door, the phone will also send a timely reminder, for forgetfulness like me is not too good. The most interesting thing is the record function, we can use the phone to take photos of the ingredients we buy, and then set the purchase date and freshness time, to remind ourselves at any time, to avoid food expiration and spoilage.
