Intelligent freshness preservation refrigerator capable of identifying varieties of fruits and vegetables

Abstract

The invention provides an intelligent freshness preservation refrigerator capable of identifying varieties of fruits and vegetables. The refrigerator comprises a freezing chamber and a refrigerating chamber. An independent freshness preservation chamber is arranged in the refrigerating chamber. The freshness preservation chamber is internally provided with a central processing unit and a circuit substrate connected with the central processing unit. Colorful freshness preservation lamps are arranged on the circuit substrate. The colorful freshness preservation lamps comprise red LED lamp beads, orange LED lamp beads, yellow LED lamp beads, green LED lamp beads, blue LED lamp beads, cyan LED lamp beads and purple LED lamp beads. The intelligent freshness preservation refrigerator further comprises a pressure sensor, a humidity sensor, an atomizing device, a camera, an image processor and a data storage which are connected with the central processing unit. The central processing unit controls the circuit substrate according to detection results of the pressure sensor and the humidity sensor as well as the varieties of fruits and vegetables. The circuit substrate controls the turned-on number and the turning-on intensity of lamp beads of different colors.

Description

technical field [0001] The invention relates to an intelligent fresh-keeping refrigerator capable of identifying types of fruits and vegetables, which is used for intelligent fresh-keeping of fruits and vegetables inside the refrigerator. Background technique [0002] Refrigerators are indispensable electrical appliances in modern life. Putting vegetables or fruits in the refrigerator can extend their shelf life. However, since vegetables and fruits cannot continue to carry out photosynthesis, the continuous consumption of respiration will accelerate the deterioration and decay of vegetables or fruits; and the implementation of light on plants in the refrigerator can allow vegetables to continue photosynthesis to offset the generation of respiration. consumption, effectively delaying the rotting speed of vegetables and achieving the effect of keeping fresh. Many existing refrigerators use an air-cooling system. The advantage of the air-cooling system is that the cooling eff...

Problems solved by technology

Many existing refrigerators use an air-cooling system. The advantage of the air-cooling system is that the cooling efficiency is very high. However, the air-cooling refrigerator will dry the vegetables and fruits in the refrigerator and make them lose moisture quickly. In this way, the moisture in the vegetables and fruits will be reduced. It is steamed dry and loses its original taste, and none of the existing refrigerators can implement the corresponding amount of light according to the amount of fruits and vegetables inside.

There are refrigerators using vacuum fresh-keeping in the prior art, but their structures are complex and require additional air extraction devices, which will also bring additional noise and power consumption. Although there are refrigerators using photosynthetic fresh-keeping lamps in the prior art, each The sensitive bands of vegetables are not the same, and it cannot implement different bands of light for different fruits and vegetables, let alone adjust the corresponding light according to the amount of fruits and vegetables
