What kind of refrigerator is a smart refrigerator?

What is a smart refrigerator? I don't intend to talk about the existing products on the market here. I won't say anything about standards. I'll just talk about what my imaginary smart refrigerator should look like.

The refrigerator creates a low temperature environment, which is mainly used to delay the deterioration of food. Then all intelligence should develop around this point, and I can only label products that avoid this point as pseudo-intelligence.

First of all, the first point should be the intelligence of temperature control. According to the seasonal external environment, whether goods are stored in the area and other factors, the temperature of the cold storage area and the frozen area is intelligently adjusted to achieve the balance between dynamic energy and use effect. I won't say much about what the refrigerator looks like now. We basically have it at home, and everyone knows it.

This article is actually an extension of the last article. The refrigerator will frost when used. Sometimes we have nothing to store in some partitions inside the refrigerator, so we raise the temperature in the corresponding area through detection and control, and then collect the melted water through the structural height difference tank. When someone uses it, the voice prompts to clean up or control the local position to start automatic discharge.

This is an expectation. Put the article into a mechanical device such as a manipulator, automatically select the appropriate partition to put it in, and say an instruction such as the name of the article when you want to take it out, and take it out automatically. This realization should take up more space, and of course it does not rule out that some people have novel ideas to realize it.

For example, the treatment of arrears and power failure, self-inspection report of fault shutdown, etc. The list will be long. As for whether the mobile phone is connected, I feel it is of little use. At most, it is used to see the running status.

First, the introduction of smart refrigerators

The so-called smart refrigerator can automatically change the mode of the refrigerator, keep the food in the best storage state all the time, let users know the quantity, freshness and quality information of food in the refrigerator anytime and anywhere through mobile phones or computers, provide users with healthy recipes and nutritional taboos, and remind users to supplement food regularly.

Second, the smart refrigerator function

1, food management function

① Know the quantity of food in the refrigerator.

② Understand the fresh-keeping cycle of food.

(3) automatically remind the food shelf life.

(4) Remind a reasonable diet.

2.IOT cloud service function

① You can check the food information in the refrigerator online through the Web.

② A shopping list can be set to remind users to buy food.

③ You can receive food information in the refrigerator by SMS.

3. Refrigerator control system

① Digital temperature control of refrigerator

② Various adjustment modes, which can be adjusted at any time as required.

(3) the actual temperature query, you can query the current temperature in the box.

Third, intelligent refrigerator temperature adjustment

For example, Haier's computer-controlled refrigerator generally has the function of artificial intelligence. Under this function, the refrigerator automatically adjusts the temperature setting according to the change of ambient temperature without manual adjustment. First, you need to unlock the display screen, then press and hold the artificial intelligence button for 3 seconds, and an artificial intelligence icon will appear, indicating that the refrigerator has entered the artificial intelligence state; If you need to exit the artificial intelligence state, press and hold the artificial intelligence key for 3 seconds while the display is unlocked, and the artificial intelligence icon will disappear. Generally speaking, in the state of artificial intelligence, it is impossible to manually adjust the temperature of cold storage, freezing or quick freezing, but the temperature of variable greenhouse can be adjusted.

If you want to manually adjust the refrigerator temperature, you need to press the refrigerator adjustment button for a long time, which will display the refrigerator temperature and enter the setting state of the refrigerator temperature. Then every time the refrigeration adjustment button is pressed, the temperature value increases by 1 degree until1degree. Press this button again, the refrigeration temperature will be displayed as, which means that the prefabricated refrigeration room will be closed. Press the refrigeration adjustment button again, the temperature value will return to 2 degrees, and so on. If there is no key operation within 5 seconds after setting, the temperature display area will stop flashing and confirm. When the OF gear is selected and confirmed, the cold storage room is closed, and when the non-OF gear is selected and confirmed, the cold storage room resumes cooling.

Compared with traditional refrigerator series products, we can find the advantages and characteristics of intelligent refrigerator, including temperature adjustment and digital control functions. These are the parts that are adjusted with reference to the problems that consumers may worry about, so that we can learn the characteristics of smart refrigerators and consider them with reference to the demand budget when purchasing.

The above suggestions are for reference only, and I hope they can help you.

In addition to retaining the basic functions of the refrigerator, the following requirements should be met:

1. Built-in deep learning artificial intelligence chip, which can learn users' usage habits;

2. The Internet of Things can be realized, and information can be exchanged with control devices such as mobile phones in real time;

3. A more user-friendly UI design can make suggestions based on user habit data.

Nowadays, many new home appliances are labeled as "smart", and the overwhelming intelligent publicity makes the products full of science and technology, and the refrigerator industry is no exception. But what is a smart refrigerator? How to judge the intelligence of refrigerator? Is one more screen really smart? Consumers often have such questions when buying smart products.

On March 1 day, 2020, GB/T 37877-20 19 "Special Requirements for Smart Refrigerators for Smart Household Appliances" (hereinafter referred to as the Smart Refrigerator Standard) was officially implemented, which solved these consumers' confused problems. This standard defines the definition and performance requirements of intelligent refrigerator, and gives the intelligent detection and evaluation methods. Haier, Midea, Hisense, Meiling and other brands participated in the drafting of standards.

Judging from the development trend of refrigerators, intelligence is an unavoidable topic, and major brands have increased their innovative investment in smart refrigerators. However, due to the lack of corresponding norms and unified standards, many smart refrigerators can only realize basic functions such as mobile phone remote control, online listening to songs and chasing dramas, and cannot give users a better intelligent experience such as actively adjusting temperature and customizing recipes.

It is clearly defined in the standard of smart refrigerator: smart refrigerator refers to a refrigerator that adopts intelligent technology and has the abilities of perception, decision-making, execution and learning (including the application ability of learning results), and comprehensively utilizes these abilities to realize specific functions. In terms of requirements for smart refrigerators, the standard defines the effects of smart functions from six aspects: temperature control, automatic defrosting, food management, fault alarm, online upgrade and third-party application services.

This standard not only sets the temperature requirement that "refrigerators should be automatically optimized and adjusted by intelligent technology", but also defines the requirements and evaluation methods for the ability of identifying and managing the freshness of raw materials. Based on the basic fresh-keeping function of ingredients, it also puts forward higher standards for the intelligent ability of refrigerators. The person in charge of Midea's smart refrigerator said that this also means that products that do not meet the standards in the future will no longer be able to call themselves "smart" so as not to mislead consumers. At the same time, the standard also regulates the security of product network connection and user information data, so that users don't have to worry about security risks such as information leakage.

This standard is the first product standard for smart refrigerators in the world, so the evaluation methods of various requirements are quite different in the drafting process. The relevant person in charge of Midea said that at present, the technical reserves of smart refrigerators of various brands are different, and the products are quite different. Without other standard references, it is difficult to get consistent results.

In the end, adhering to the goal of promoting the development of the industry, the standard has higher requirements for smart refrigerators, which is technically difficult for some enterprises. "Intelligent technology is developing rapidly, and the formulation of standards must be forward-looking in combination with the actual situation in order to promote the development of the smart refrigerator industry." An industry insider said.

In addition, in order to promote the development of refrigerator intelligence, the standard also defines the evaluation method of refrigerator intelligence level. The intelligent grade evaluation of refrigerator includes two parts: intelligent function effect and intelligent ability.

The total score of refrigerator intelligent function is 100, and the test items include temperature control (15%), automatic defrosting (15%), food management (25%), fault alarm and analysis (15%), and third-party application services (/kloc-

The total score of intelligent ability of refrigerator is also 100, and the data processing interaction ability, voice recognition ability, virtual animation ability, intelligent scene selection mode, image recognition ability, audio-visual function, etc. 1 1 intelligent feature functions are evaluated respectively. The weighted average effect of intelligent function (70%) and intelligent ability (30%) of refrigerator directly reflects the intelligent degree of refrigerator.

The drafter of a standard said that the standard can be used in combination with the group standard "Technical Specification for Evaluation of Intelligent Level of Household Refrigerators". This group standard classifies the intelligence of refrigerators according to the score of intelligence degree. At the same time, the standard rating of smart refrigerators involves the test methods of some indicators, and can also be tested according to the requirements of group standards.

Without strict intelligent boundaries,

Now the intelligence can only be said to be "upgraded".

Just with the needs of life, on the basis of the original function of the refrigerator, some modules are gradually added.

Such as adding sensors, lights, sound and voice modules to hardware,

The software is associated with intelligent terminals (mobile phones, etc.) through algorithms. ).

There are gradually databases, that is, applications such as big data and cloud computing. According to your behavior habits, work out the short-term needs that match you.

Automatically identify the shelf life of food;

Intelligent area temperature management;

The big screen can directly place an order to buy fresh food.

Types of refrigerators that can intelligently control refrigerators and intelligently manage food. Like Hisense smart refrigerator BCD-558WGBP/T, it has the functions of food management, entertainment, time-sharing electricity recording, IOT cloud service, electronic photo album, Internet access, health housekeeper and so on, and has seven function conversion modes. The most unusual thing is that it is completely intelligent. The operating interface on the door panel is a tablet computer. Unlike some smart refrigerators, their appearance is not "smart", which really makes people wonder how high their IQ is.
