I want to buy a refrigerator, but I don't know what to pay attention to.

Let's start with the main functions of the refrigerator.

First, the fresh-keeping function of vegetables and fruits

It means extending the shelf life of fruits and vegetables as much as possible. At home and even around the world, refrigerators have been used continuously by controlling the temperature and humidity, and the temperature of the refrigerating room can be kept between 0- 10℃ and kept fresh.

Second, freeze and refrigerate raw poultry meat.

At low temperature, especially when the temperature drops below-10℃, the water in the meat turns into ice, resulting in an environment where bacteria cannot grow and develop. However, when the meat was thawed and recovered, the bacteria began to grow and reproduce again due to the increase of temperature and the exudation of gravy. Therefore, when meat is stored at low temperature, it must be kept at a certain low temperature until it is eaten or processed, otherwise the quality of meat cannot be guaranteed. The cold storage of meat can be divided into chilled meat and frozen meat.

1. chilled meat: it is mainly used for meat stored for a short time, and the central temperature of meat is usually reduced to about 0℃ ~ 1℃. Specifically, meat should be cooled to about -4℃ and kept at-1℃ ~ 0℃ before it can be put into the refrigerator. The cooling time of pork is 24 hours and it can be stored for 5 ~ 7 days. After cooling, a dry film is formed on the surface of the meat, which prevents the growth of bacteria, slows down the evaporation of water and prolongs the storage time.

2. Frozen meat: the meat is quickly and deeply frozen, so that most of the water in the meat is frozen into ice. This kind of meat is called frozen meat Frozen meat is more storable than frozen meat. Meat is usually frozen at a temperature below -23℃ and stored at about-65438 08℃. Meat can be stored for 4 months at-18℃. In order to improve the quality of frozen meat and restore the original taste and nutritional value after thawing, at present, most professional cold storage adopts quick freezing method, that is, the meat is put into a quick freezing room at -40℃, so that the meat temperature is quickly reduced to below-18℃. This is called quick freezing. The freezing speed is very important. For example, in winter, white striped chicken and meat can be frozen outside the north window, but the fresh-keeping ability is much worse than that of qualified refrigerators, because the freezing speed is not fast enough.

It is common sense that "deep freezing and quick freezing" can keep fresh. It is also the principle of refrigerator design.

Second, choose the refrigerator to start quickly

Refrigerator products China enterprises have complete R&D capabilities, and many world-class brand refrigerators are also OEM by China enterprises. When choosing a refrigerator, according to the principle of the refrigerator and the needs of use, only choose the right model, not superstitious about any brand. Never trust advertisements. If you trust them, you will have to pay more money:)

1, does it bring some fancy functions you don't need, but you have to pay more for it? For example: display outside the box, set the temperature inside the box; Zero-degree preservation and the like.

The reason is that the temperature setting inside the box is enough, and the temperature setting outside the box is only decorative and has no practical value. It is common sense that "deep freezing and quick freezing" can keep fresh; And "zero-degree preservation" is pure nonsense, it's a joke, hehe.

2. After correctly understanding the meaning of "quick freezing ability", the understanding of "publicity" of refrigerator.

3. Is it obvious that the "brand" sells at a high price?

In fact, many users mistake the refrigerator for furniture or facade. These people also don't know how to choose refrigerators according to their performance, but choose coats or jackets according to the appearance of brands. I hope this kind of users will start thinking, which is an important step out of the misunderstanding.

4. Total volume (nominally there will be water). Don't associate this with "style" and "face", it is only related to your "convenience of buying food and eating habits".

5. What are the volumes of cold storage and freezing room respectively? Because the size of the freezer has a great relationship with its power consumption.

6. In fact, there is the question of whether the cold storage and freezer are upside down (frozen below and hidden above). However, on the one hand, there are few "anti-reverse" refrigerators at present, on the other hand, the anti-reverse effect of the direct-cooled refrigerator you choose is much smaller than that of the air-cooled refrigerator, so I won't discuss it here.

7. Climate type of refrigerator. This is a question of the upper and lower limits of the ambient temperature.

8. How about the door seal? Observe whether it is regular, smooth (or concave and convex) and tight; What about elasticity and texture? You'd better take a flashlight, turn it on and put it inside to see if there is any light leakage.

9. What about the door and the "hinge" of the door? If it is deformed in the future, it will be enough.

10, some people like to put things on the refrigerator, such as microwave ovens, so watch carefully. Many refrigerators can't do this safely. The shell is preferably the same steel plate.

1 1. The number, position and height of "shelves" (including "door frames") in the refrigerator are convenient and reasonable, which is suitable for your use habits.

12. The refrigerating room has a drain hole. Observe its position and "exquisiteness" to see if it can be convenient and smooth.

13, the size of the refrigerator relative to the position where you want to put it, don't put it "full", leave some places for heat dissipation, so that it can work normally.

14, observe the power plug and power cord of the refrigerator. If the quality is not good, avoid it. Yes, I believe you can judge its quality.

15. Finally, remember, what you want to buy is a refrigerator, which is used to refrigerate frozen food. All the functions are simple.

Here's what you don't have to pay attention to, but XS likes to promote:

1. Safety of refrigerant. What is flammable and explosive? That's alarmist. 2. Various "sterilization" methods.

3. Low "satisfactory" power consumption. They don't even know how you use the refrigerator. How did they get that ridiculous data? For example, the power consumption is directly related to the frequency of refrigerator door opening and closing and the temperature difference between inside and outside the refrigerator caused by the position where you put the refrigerator. How did they predict this "frequency" and "location" in advance?

4. About "Freon is harmful to human body". There is an article about Mr. Zhang Gong in this altar, which is very clear, so I won't go into details.

5. Other fancy things. For example, one day, someone tells you that a refrigerator can play music, so it will cost you hundreds of dollars more. I think you will have your own ideas.

6. Gifts, gifts are cheap, the quality of gifts is not guaranteed, and the wool is on the sheep.

Iii. Precautions for the purchase and use of refrigerators

First of all, compared with indirect cooling, direct cooling is suitable.

Household refrigerators can be divided into indirect refrigeration type and direct refrigeration type according to the refrigeration mode in the box. Indirect cooling refrigerator is commonly known as frost-free refrigerator, and direct cooling refrigerator is commonly known as frost-free refrigerator. Indirect cooling refrigerator and direct cooling refrigerator have their own advantages and disadvantages, and how to choose is a problem that users are very concerned about. Some people think that choosing a direct-cooling refrigerator is a more suitable choice for ordinary consumers, mainly based on the following considerations.

1. Low energy consumption can not only save the use cost, but also be beneficial to environmental protection.

Generally, if a 200-liter indirect refrigerator consumes 1.4kWh/24h a day and its life cycle is 12 years, the total power consumption during its service life is1.4× 365×12 = 6132kwh. The daily power consumption of direct-cooled refrigerators with the same or similar volume is generally 0.2 less than that of indirect-cooled refrigerators. 0.3kWh/24h, converted into expenditure, the whole service life cycle will save 438 yuan? 657 yuan. In addition, reducing power consumption can also reduce the amount of carbon dioxide emitted to the environment during coal-fired power generation in thermal power plants, which indirectly contributes to environmental protection.

2. Low noise is suitable for the current public housing conditions.

At present, the living area of domestic residents is limited, and most consumers put refrigerators in the living room (hall) or even the bedroom, which is very sensitive to the noise of refrigerators. For refrigerators of the same size, the measured noise of indirect cooling type is 2? Higher than direct cooling type. Three decibels. It's nothing outdoors, but it may be annoying enough indoors. Therefore, as far as housing conditions are concerned, it is better to choose a direct-cooling refrigerator.

3. Low voltage has little effect on direct cooling type, but it hinders indirect cooling type.

The problem of voltage instability in most parts of China is far from being fundamentally solved, especially during high temperature in summer. In recent years, some indirect refrigerators introduced in the domestic market have reversed the freezer and freezer, and installed the evaporator in the freezer below. The refrigeration of the upper refrigerating chamber depends on the lower evaporator. Cold air is forced into the upper refrigerating chamber by a fan motor, and then the stored food is cooled. The biggest disadvantage of this refrigerator is that it requires high voltage for the city network. Because once the city grid voltage drops by 10%, the rotation speed of the single-phase shield pole fan motor will also drop by about 10% accordingly. This will cause the upper refrigerator to be too hot due to insufficient cold air circulation, which will lead to food deterioration. If you choose a direct-cooling refrigerator, this phenomenon will not occur.

Second, the climate type can not be ignored.

Few people pay attention to the climate type when buying refrigerators. In fact, this cannot be ignored. Especially in the case that the summer climate in our country is persistent and the general high temperature is inevitable, we should pay more attention to it. It is related to the interests of every refrigerator consumer. The nameplate on the back of the refrigerator box is marked with the climate type of the refrigerator, and the "technical specifications" column of the refrigerator instruction manual also indicates the climate type. So, what does it mean to write down the climate type? What's the role? Household refrigerators are divided into four categories according to climate types. Sub-temperate type (SN), its suitable environmental temperature is: 10℃? 32℃; Temperate type (n), the suitable environmental temperature is 65438 06℃? 32℃; Subtropical type (ST), the suitable ambient temperature is: 18℃? 38℃; Tropical type (T), the suitable ambient temperature is: 18℃? 43℃。 Refrigerators with different climate types have different design requirements due to different environmental conditions. If it is used beyond the design temperature, the efficiency will decrease and the energy consumption will increase; In addition, the machine is damaged and its service life is shortened.

At present, most refrigerators on the domestic market are temperate type (N), at 16℃? In the temperature range of 32℃, all performance indexes can be achieved, which basically conforms to the actual temperature situation in most parts of China. However, with the global warming in recent years, the summer temperature in China has also risen for a long time and on a large scale. In some places, sometimes the temperature has exceeded the upper limit of the ambient temperature (32℃) of temperate (N) refrigerators, and then the refrigerators will keep running, which makes many temperate (N) refrigerators have unexpected failures when they are used in summer. Judging from the climate trend, the temperature seems to be getting warmer in summer. Therefore, it is a scientific and safe choice to choose subtropical (ST) refrigerator.

Third, energy-saving refrigerators don't save money.

Energy-saving of household appliances has become the eternal theme of the development of household appliances, but the development of energy-saving technology of household appliances is a slow and gradual process. At present, whether some so-called energy-saving refrigerators have more advantages than disadvantages, more disadvantages than advantages, or weigh the advantages and disadvantages needs further deliberation and evaluation. The reasons for this are:

1. It just changes the way and time of energy consumption.

At present, most energy-saving refrigerators adopt the energy-saving way of thickening the refrigerator box (insulation layer), and some are also equipped with imported high-efficiency compressors. The adoption of these measures increases the production cost of refrigerators, but it is ultimately reflected in the price of refrigerators. Therefore, the prices of many energy-saving refrigerators in 800 yuan are higher than those of non-energy-saving refrigerators with the same (near) specifications, and this cost is enough to consume 0.3kWh/24h of electricity, about 12 years.

2. Saving energy does not necessarily save money.

In fact, the current direct-cooled refrigerator (commonly known as frost-cooled refrigerator) has a capacity of about 200 liters and a power consumption of 0.8? 0.9 kWh /24 hours. So I paid 800 yuan more money to buy an energy-saving refrigerator with a volume of about 200 liters and a power consumption of 0.6 kWh/24 hours, but the money saved after using 12 years was suddenly taken back to the manufacturer, so this energy-saving refrigerator saves energy but does not save money.

3. Loss of living space

In order to ensure the effective volume in the refrigerator, the overall size of the refrigerator with thick foam insulation layer has to be increased, occupying more living space (including room area). It can be seen that increasing the thickness of the insulation layer of the refrigerator should never be the first choice for energy saving.

Fourth, the quick-freezing function has not been realized.

1. Definition of quick freezing

What is quick freezing? According to page 1 17 of Encyclopedia of Household Refrigerators (published by Knowledge Press 1992 17), quick freezing is a process of reducing the temperature of food to be frozen from 0℃ to -5℃ within 30 minutes. Because the water in food cells is 0℃? The temperature between -5℃ is the highest temperature for ice crystal formation, and the shorter this stage, the better. Otherwise, after slow freezing, the water in food cells will generate large ice crystals, which will cause cell rupture and lose some nutrients when thawing. Quick freezing, food cells are less damaged, food taste and nutrition are less damaged, and it can basically remain the same.

2. The current national standard for household refrigerators has neither a definition of quick freezing nor a specific evaluation method.

The current national standard for household refrigerators comes from GB 8059+0? In GB8059.4, there is no such term as "quick freezing" in either the old version 1987, 1993 or the latest revision 1995. There is obviously no such clause in the technical requirements, let alone establishing an assessment method for it. However, some refrigerator manufacturers' advertisements wrote: "The national standard stipulates that quick-frozen and fresh-keeping refrigerators should pass through the largest ice crystal generation area within 30 minutes, while the new generation refrigerators only need 20 minutes, which is also a high level in the world refrigerator industry." However, what is the "national standard" cited in this publicity? When will it be promulgated?

3. What does it mean that it takes a long time to pass this temperature zone in the actual freezing capacity test?

According to the current national standard for refrigerators, every100L effective volume freezer should be able to freeze at least 4.5kg of frozen load (lean beef with similar thermal characteristics) from 25℃ (sub-temperate (SN), temperate (N) and subtropical (st) refrigerators) or 32℃ (tropical (T) refrigerators). This is the freezing capacity of the refrigerator. If the freezer is less than100L, its freezing capacity should not be less than 2kg. The standard also stipulates that the freezing capacity of each refrigerator must be marked on the nameplate on the back of the box. The refrigeration load of 4.5kg occupies a small part in the volume of 100 liter. Even so, these freezing loads pass through 0℃? How long does it take at -5℃? From the relevant laboratories engaged in refrigerator quality supervision and testing for a long time by the quality and technical supervision department, and from the freezing capacity test of refrigerators sampled in the market, it is known that these freezing loads pass 0℃? When the temperature is -5℃, the time required is as short as 5? Six hours, nine minutes? 10 hour 30 minutes and 5 seconds? Compared with 10 hour, only 1/20? 110 time. So those refrigerators that flaunt quick-freezing ability don't know how much load they put in the freezer for quick-freezing test? Is it 1kg meat or a piece of meat? I don't know what ambient temperature it was tested at.

4. Will the current household refrigerator have quick freezing ability?

By comparing the national standard of household refrigerator with the actual test of refrigerator cooling capacity, the refrigerator passed 0℃? It takes a long time for the temperature to reach -5℃, which makes people doubt and deny whether the current household refrigerator will have the ability of rapid freezing.

Five, the size is enough.

Buying a household refrigerator should not only meet the demand, but also weigh the economy. For example, the determination of body size depends on comprehensive factors such as eating habits, convenience of food procurement, housing conditions and family economic situation. Too small a size will bring inconvenience to the use of the refrigerator. Too large, but also has shortcomings, such as high price, large power consumption, more space. At present, there are dozens to three or four hundred liters of household refrigerators on the market. More than 60% of households bought 180? For a refrigerator with a capacity of 250 liters, the price difference is 10 for each volume difference. 15 yuan. And the specifications under a series generally differ by 20? This is due to the limitation of the size of the molding die for the refrigerator and freezer. Some brands of household refrigerators seem to have many specifications and sizes, but as long as they are a series, they are often just one or two different combinations of cold storage rooms and freezing rooms with the same specifications and sizes. In other words, even if you choose a certain brand of household refrigerator, you can't increase or decrease its effective volume at will, and you can only choose between dozens of liters. So, don't be greedy. On the contrary, abandoning the big has many advantages. If 200 liters is enough, there is no need to have 230 liters. Moreover, the first-generation household refrigerators used by families in China rarely exceed 200 liters. If it is inconvenient to use it for more than ten years, you should not be greedy. Giving up too much volume has great advantages.

1. Give up the total volume and save one-time investment.

From the price point of view, the total volume is 30 liters smaller, and the first investment can save 300 yuan? 450 yuan. Recent sales information from commercial channels shows that the situation is not satisfactory. Household refrigerators with a volume of more than 250 liters are difficult to sell, accounting for only about 10% of the total sales, while refrigerators with a volume of about 200 liters have the most market, accounting for about 62% of the total sales. In fact, the determination of household refrigerator size is also closely related to climate, eating habits and the convenience of food procurement. The more developed the layout of commercial outlets and non-staple food markets, the less the volume demand of refrigerators. The climate in southern cities is hot, so families generally need a small refrigerator.

2. The freezer is large, saving the use cost. The volume of the household refrigerator is 30 liters smaller, but the small place is particular. The capacity of the refrigerator is 30 liters, and the power consumption is basically unchanged. But if it is put in the freezer, it can save about 0.2kWh/24h. If converted into currency, it can save 534.36 yuan in the service life cycle (calculation method: 0.2×365× 12×0.6 1 (current electricity price in Shanghai) =534.36 yuan). Plus the money saved when purchasing, the benefit is nearly 1000 yuan. In addition, from the perspective of quality of life and diet nutrition, it is good to eat fresh food. Frozen food should not be stored for a long time, otherwise food will lose more nutrients. The freezer of household refrigerator should not be an extension of the cold storage of food supermarket, and ordinary families don't need such a small "cold storage". The freezing room of household refrigerator can only meet the storage and turnover of a small amount of frozen food. Therefore, it is obvious that the freezing chamber volume of household refrigerators need not be greedy.

Sixth, the antibacterial function needs to be confirmed.

Recently, there has been an antibacterial wind in the domestic refrigerator market. Various types of antibacterial household refrigerators have appeared one after another, but due to the current product standards of household refrigerators, it is impossible to judge and evaluate this "new thing". Some say antibacterial, some say sterilization, and even more ambiguous antibacterial. As a result, the statement is becoming more and more vague, but the concept is becoming more and more unclear.

1. The antibacterial object and method are not clear. Adding some trace elements (some directly say "antibacterial agent") to the surface coating of plastics or other materials is said to be antibacterial, but there are two puzzling places. First of all, the antibacterial subject is not clear. Where is the so-called antimicrobial resistance? Is it bacteria in food, or mold easily produced on the plastic liner or coating surface of household appliances? Secondly, the antibacterial method is not clear. As far as the refrigerator is concerned, the usage habit tells us that food generally does not contact with the liner directly, but contacts with the liner through media such as containers and packaging materials. Then, how does antibacterial agent exert its antibacterial effect, by physical or chemical methods? Antibacterial household refrigerators are not clear about this.

2. The side effects of antibacterial materials are unknown.

Some engineering plastics are easy to be contaminated with some bacteria and microorganisms due to their performance. After adding one or several elements, the chemical properties of plastics become more stable. It is not excluded that some bacteria and microorganisms on its surface may be really inhibited, but is there a blind spot in the understanding of this new material? Whether things have been tested for some invisible side effects. Will it cause new pollution hazards to the refrigerator? This in turn affects the stored food. For chemical materials, there are many problems that are temporarily incomprehensible and can't see the consequences. Therefore, contact with food, health-related chemicals, things to ponder, must not be ignored. We sincerely hope that the manufacturer can provide a convincing verification conclusion indicating the source.

3. The antibacterial timeliness is unknown

Even if the antibacterial household refrigerator really has the claimed antibacterial effect, what is the antibacterial time limit of these "antibacterial agents"? Can it be synchronized with the life cycle of its products? Who can confirm this?

4. The promotion of antibacterial home appliances is not vague.

There is a * * feature in the propaganda language of antibacterial refrigerator, which likes to use qualitative analysis and inference to explain the problem, but there is no quantitative analysis, and there is no scientific comparative experimental data to support it. Assuming that the mixed "antibacterial agent" can really kill or inhibit the bacteria in food, we should use verified conclusions to solve the confusion for consumers, rather than specious, ambiguous and puzzling inferences.

Seven, refrigerator preservation does not conform to the habit.

Recently, some refrigerator manufacturers have set up ice temperature fresh-keeping rooms (or micro-freezing rooms) and fruit and vegetable fresh-keeping rooms on household refrigerators to meet the fresh-keeping requirements of short-term food storage. Some refrigerators' fruit and vegetable fresh-keeping rooms are not small in volume, claiming that they can hold dozens of kilograms of fruits and vegetables at a time. The ice temperature fresh-keeping room is specially used to store frozen and unfrozen food. This refrigerator, which originated in Japan, was developed and designed mainly considering the Japanese habit of eating sashimi. The prospect of China market may not be optimistic. Because: First of all, most people in China don't have this hobby. People who used to have this hobby occasionally get sick because they were afraid of water pollution, and the health and epidemic prevention department has repeatedly warned against eating fish, meat and other foods raw to avoid getting sick. Therefore, in the daily family diet, not many people will put raw food in the ice temperature fresh-keeping room for a while before taking it out. Secondly, few people will deliberately go out to buy fresh non-staple food for dinner in the morning and then go home and put it in the ice temperature preservation room, so that they can take it out and cook it when they get home from work at night to avoid the destruction of nutrients when food is frozen and thawed. Third, how many families in China have the habit of buying fresh vegetables and putting them in the fresh-keeping room for a few days before taking them out? This is an act that goes against the habits and logic of daily life. It can be seen that the total volume of household refrigerator is moderate, and the volume of freezer is appropriate, which will bring you unexpected benefits and help you develop healthy eating habits.

8. Inverted refrigerators have many disadvantages.

Usually, the freezing room and refrigerating room of household refrigerators are set with the freezing room above and the refrigerating room below. Recently, however, an inverted household refrigerator has appeared in the market, that is, the traditional household refrigerator is turned upside down, the freezing chamber is put down, and the refrigerating chamber is moved up. It is said that this is to reduce the number of times users bend over and squat, and to reduce the "labor intensity" of consumers, which cannot be said to be unattractive. But from another point of view, some problems will be poured out when the refrigerator and freezer are inverted. Whether it is direct cooling type or indirect cooling type, most inverted household refrigerators now prefer to design the lower freezer in the form of drawer. There are open drawers and hidden drawers, and you can only see them when you open the door. This design is said to facilitate the separate storage of frozen food and avoid the escape of a large amount of cold air, because only part of the frozen space needs to be exposed when accessing frozen food (this function is even promoted as saving electricity). However, this design has a problem that consumers are not easily aware of, that is, it will lose effective freezing space. There is bound to be a difference between the nominal volume of the drawer refrigerator and the effective volume that consumers can actually use. At present, this difference is not less than 10% of the total effective volume of the freezer. As a manufacturer of household refrigerators, it is unwilling to mark the effective freezing space because it will affect the sales pricing of household refrigerators. In fact, as long as it does not violate the current national standards for household refrigerators, which household refrigerator manufacturer does not want to use the full policy? But this is unfair to consumers, because the nominal (that is, nominal) frozen space bought with money does not match the actual frozen effective space.

Another problem under the freezer is particularly prominent in household indirect refrigerators. In order to realize a certain amount of cold air circulation, compared with the fan motor installed on the freezing chamber of the ordinary traditional household indirect cooling refrigerator, the running speed of the fan motor of the indirect cooling refrigerator must be increased by about 10%. When the motor rotates at a high speed, the noise is bound to increase. Coupled with the design of the long wind tunnel, there will be a lot of * * * noise that annoys users.

Another problem that is easily overlooked when using inverted indirect cooling household refrigerators is that when the voltage of the city network fluctuates, the upper refrigerating rooms of all household refrigerators will not be cold enough (especially during the peak period of electricity consumption in summer). Because the indirect cooling refrigerator adopts single-phase covered pole motor for forced cold air circulation, it is sensitive to voltage fluctuation of urban power network. When the city grid voltage drops by 10%, its rotating speed will also drop by about 10% accordingly, which will easily lead to insufficient cold air circulation in the refrigerator and high temperature in the refrigerator.

The traditional household refrigerator may look tacky, but it has stood the test of time after all. Most of the problems encountered have been solved. Innovation itself is not a bad thing, but it should not harm the interests of consumers first. Secondly, unfavorable factors in the use process should not be increased.

Nine, the auxiliary function is not practical

The essential function of household refrigerator is to be able to refrigerate and use it to refrigerate or freeze food. In addition, they are all auxiliary functions. For example, the temperature inside the box is displayed outside the box, the temperature inside the box is adjusted outside the box, the refrigerator will automatically make ice, and the refrigerator door is decorated with pictures. The possession of these auxiliary functions will inevitably increase the production cost and will eventually be passed on to consumers through the selling price. In addition, what will this auxiliary function bring to daily life? China people seldom have the habit of drinking at ordinary times (outside meals), and visitors always treat each other with tea, far from forming the habit of entertaining guests with wine and ice. Then, what is the practical significance of dozens of ice cubes that can be made automatically every day for ordinary families? And life experience tells us that the temperature of the refrigerator does not need to be adjusted many times a year, so there is little difference in temperature adjustment inside and outside the box. There is no need to track the temperature of the refrigerator, so there is no need to display the temperature inside the refrigerator from the outside.

In addition, the door with a picture is only an ornamental function, which has been watched for more than ten years. Can I look at a picture every day without getting bored? Most importantly, refrigerators with many auxiliary functions have high energy consumption and high failure probability, which sometimes add a lot of trouble to people.

X. how to determine the brand?

Some people have made a survey of consumers who buy a brand refrigerator. The results are divided into three categories: first, other products of this brand have been used before, and the quality is good, leaving a good impression; Second, without considering any problems, I was only impressed by the product design; The third is to follow the advertisement and follow the promotion. If the first kind of consumer decision has some factual basis, then the second and third kinds

Class consumers are a little blind. In fact, the decision-making of the first type of consumers is also unscientific. There are many products under a brand, one of which is better or may be second to none, all of which are first-class, which is not surprising and certainly unrealistic. Therefore, when choosing the brand of specific household appliances, more consideration should be given to some household appliances that produce a single product. Long-term and repeated production of an electrical appliance has more or less learned some lessons and transformed them into upgrading of its products. When determining the brand, it is better to think rationally, and it is unwise to take it for granted or follow the advertisement. Self-boasting and "cordial and pleasant" service promises in advertisements are often full of complaints. Hisense 2 12DG can meet the national 6A standard.
