Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof. The refrigerator comprises a refrigerator body, a refrigerating system, a detection system and a control system. A storage chamber is defined by the refrigerator body; the refrigerating system is configured to provide cold energy for food stored in the storage chamber; the detection system is arranged in the storage chamber; and the control system is configured to control the detection system to apply thrust to the food and obtain the moving distance generated when the detection system applies the thrust so as to adjust operation parameters of the refrigerating system according to the moving distance. According to the refrigerator, thrust can be applied to the food by arranging the detection system, so that the control system determines the freezing state of the food based on the moving distance generated after the thrust is applied by the detection system, the freezing point of the food is accurately controlled, and nutrition loss and quality and taste reduction of the food in the thawing process are avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator and a control method thereof. Background technique [0002] Freezing technology is the most common and effective method to extend the shelf life of food. For example, frozen meat is stored at -18°C, which can generally be stored for 6 to 12 months. But the frozen food is not only inconvenient to thaw, but also the quality and mouthfeel of the food obviously decline after thawing. And how to make the food material that eats in a short time keep not freezing is the problem that needs to be solved urgently. [0003] At present, sensors are mostly used to obtain food temperature values ​​to determine whether food is in a frozen state, such as infrared sensor edible non-contact sensors, such sensors cannot accurately obtain food temperature values, resulting in the inability to accurately determine whether food is in a frozen state; For the contact tem...

AI Technical Summary

Problems solved by technology

[0003] At present, sensors are mostly used to obtain food temperature values ​​to determine whether food is in a frozen state, such as infrared sensor edible non-contact sensors, such sensors cannot accurately obtain food temperature values, resulting in the inability to accurately determine whether food is in a frozen state; For the contact temperature sensor of the probe temperature sensor, because it needs to be inserted into the food content, the structure of the food will be damaged, and the operability is poor, so it cannot be accepted by users
