Problems solved by technology

However, in the actual application process, the gas content value detected by the gas content sensor has deviations, the accuracy is not high, and it cannot accurately reflect the change of the gas content in the refrigerator. When some food materials have deteriorated, the user cannot be promptly reminded to take measures measures, leading to poor user experience

Embodiment Construction

[0029] figure 1 is a schematic diagram of a refrigerator 10 according to an embodiment of the present invention, figure 2 is a schematic block diagram of a refrigerator 10 according to one embodiment of the present invention.

[0030] The refrigerator 10 may generally include: a box body 110 , a refrigeration system disposed in the box body 110 , a gas content detection device 300 , and a control device 400 . The box body 110 forms at least one storage compartment 111 inside. The number and temperature zones of the storage compartments 111 can be set arbitrarily. In this embodiment, only one storage compartment 111 is used for illustration, and the storage compartment 111 is a refrigerated compartment. Those skilled in the art should be fully capable of making extensions on the basis of understanding the present embodiment, which will not be shown here one by one.

[0031] The refrigeration system may be a compression refrigeration system. A compression refrigeration sys...

Abstract

The invention provides a refrigerator and a control method thereof. The refrigerator is internally provided with a gas content detection device which is configured to detect the gas content of to-be-detected gas in a storage chamber of the refrigerator; and the control method comprises the following steps of: acquiring a gas content detection value of the to-be-detected gas; obtaining an aging offset coefficient and a temperature compensation coefficient of the gas content detection value; correcting the gas content detection value according to the aging deviation coefficient and the temperature compensation coefficient to obtain a gas content correction value; judging whether a difference value between the gas content correction value and a set gas content standard value exceeds a first set threshold value or not; and if yes, driving the refrigerator to send out a first prompt signal. by using the aging deviation coefficient and the temperature compensation coefficient to correct the gas content detection value, the change condition of the gas content in the refrigerator can be accurately monitored, so that the influence of the aging degree and the temperature on the accuracy of the detection result is reduced or avoided, and the monitoring accuracy of the refrigerator on the gas content monitoring process is improved.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a refrigerator and a control method thereof. Background technique [0002] In the refrigerator, a low-temperature fresh-keeping storage environment is formed inside to store perishable food materials. Although refrigerators can prolong the shelf life of ingredients, when the ingredients are stored for too long, the freshness will still be reduced or even spoiled. [0003] As the freshness of the ingredients decreases or deteriorates, the specific gas content in the refrigerator will change. Some existing technologies install gas content sensors for detecting the gas content in the refrigerator to monitor the freshness and / or deterioration of the ingredients in the refrigerator. degree. However, in the actual application process, the gas content value detected by the gas content sensor has deviations, the accuracy is not high, and it cannot accurately reflect the change of the gas conte...
