Smart Home Appliances: Sensors Make Refrigerators Interact Smartly

When people use the refrigerator, they often have a question, what degree should the temperature of the refrigerator be adjusted to achieve both freshness and energy saving? As a household appliance that needs to be turned on 24 hours a day, the temperature adjustment of the refrigerator has a great impact on energy consumption. At the same time, the temperature setting of the refrigerator also needs to change with the seasons.

With the continuous development of science and technology, the emergence of smart refrigerators has solved many problems that people encountered when using refrigerators. Under the epidemic situation, the demand for large-capacity, low-power consumption, sterilization and fresh-keeping functions is obvious, and more and more high-end smart refrigerators are gradually occupying the consumer market.

The popularization of technologies and functions such as large capacity, partitioned storage, sterilization, pesticide residues, and intelligence in the refrigerator market has further promoted the trend of the entire market to develop towards high-end. With the expansion of the middle and high-income population, people’s demand for food preservation, food health management, and product appearance design has increased, and the market share of high-end refrigerator products has gradually increased.

1. Intelligent temperature control

The realization of intelligent functions of refrigerator series is inseparable from the information transmission of sensors. Smart sensors suitable for refrigerators, such as temperature and humidity sensors, TVOC gas sensors, human sensor sensors, negative ion generators, etc., can provide innovative directions for the intelligent development of refrigerators.

The interior of the refrigerator is installed with high precision, stable performance, and fast response. The temperature and humidity sensor can measure the temperature and humidity of the indoor environment, transmit the value to the control board, and intelligently adjust the temperature and humidity in the refrigerator to keep it within an appropriate range. It perfectly solves the problem of manual temperature. Regulatory disadvantages. In the double-door refrigerator, the temperature and humidity sensor can also be installed in the hinge box of the refrigerator to measure the external ambient humidity of the refrigerator, calculate the dew point temperature, and control the heating wire in the vertical beam to exceed the dew point temperature, so as to prevent the vertical beam dew from dripping on the ground.

2. Sterilize and keep fresh, eliminate odor

Because the food stored in the refrigerator is too much and too miscellaneous, the food is easy to stink in the closed space of the refrigerator. Sometimes, if spoiled food is not cleaned up in time, it will cause the refrigerator to develop an odor. Odor is a mixture of various harmful gases. The TVOC gas sensor installed in the refrigerator can monitor the odor produced by various harmful gases. When the odor occurs, the linkage deodorization device will deodorize the refrigerator.

After long-term use of traditional refrigerators, it is easy to breed bacteria such as Bacillus, Staphylococcus, Yersinia, Aspergillus, and Penicillium. These bacteria not only affect the shelf life of food, but also endanger health. Install the negative ion generator NAC-6KA in the refrigerator, which can continue to generate high-concentration negative ions. When negative ions are attached to the surface of harmful microorganisms such as bacteria and viruses, they will combine with strong oxyhydroxides to deactivate harmful microorganisms such as viruses and bacteria due to oxidative decomposition of proteins, thereby achieving the effect of killing microorganisms and realizing the sterilization inside the refrigerator. Provide a fresher and more hygienic storage environment for ingredients and protect the health of the whole family.

3. Smart screens display high-end experience

With the continuous improvement of refrigerator intelligence, more and more attention has been paid to the human-computer interaction between users and refrigerators. Currently, many smart refrigerators have displays. Install the human detection sensor in the gap between the double doors of the refrigerator. When the human body is close to the refrigerator for a certain distance, when the human sensor detects that the human body is approaching, it will output an analog model to the main unit of the refrigerator, and the main unit will control the refrigerator display to turn on automatically; It improves the high-end smart experience of the refrigerator and saves energy when the refrigerator is not turned on.
