Abstract

The invention relates to a micro-fluidic detection system for a refrigerator, a control method of the micro-fluidic detection system and the refrigerator. The microfluidic detection system comprises a microfluidic biochip and a detection cell formed in the microfluidic biochip, the microfluidic biochip is provided with a sample inlet, a communication port and a buffer solution inlet, and the sample inlet, the detection cell and the communication port are sequentially communicated through a micro-channel to form a main channel; a sample liquid in contact with the sample inlet is allowed to flow into the detection cell through the sample inlet and the micro-channel in sequence, and the buffer liquid inlet is communicated with the micro-channel connected between the communication port and the detection cell; the detection mechanism is used for detecting the detection pool to obtain preset detection parameters of the sample liquid; the buffer solution driving device is communicated with the buffer solution inlet and is used for promoting the buffer solution to flow into the main channel through the buffer solution inlet and flow out through the sample inlet, so that the buffer solution is used for cleaning the main channel, the automatic cleaning of the microfluidic detection system is realized, the structure and the control logic of the microfluidic detection system are simplified, and the volume of the microfluidic detection system is reduced.

Description

technical field

[0001] The invention relates to refrigeration and freezing technology, in particular to a microfluidic detection system for a refrigerator, a control method thereof, and a refrigerator. Background technique

[0002] With the improvement of people's living standards, it is usually necessary to detect pesticide residues, viruses, nutritional elements or other aspects of some food materials eaten in daily life, so as to obtain the status of food materials qualitatively or quantitatively. For example, due to the abuse of pesticides, the fruits and vegetables and agricultural by-products we buy daily may have excessive levels of pesticide residues. If the problem of excessive levels of pesticide residues in these foods is not discovered in time, human consumption will cause great harm. For another example, the breastfeeding currently advocated is the best feeding for babies only when the breastmilk has normal nutritional value. The content of elements is reduced ...

Embodiment Construction

[0053] The present invention firstly provides a microfluidic detection system for refrigerators. The microfluidic detection system of the present invention is used for qualitative or quantitative detection of the preset detection parameters of the sample liquid. The preset detection parameters can be, for example, used for Pesticide parameters indicating whether the amount of pesticide residues exceeds the standard and / or the specific value of the amount of pesticide residues, nutritional parameters used to indicate whether the nutrient elements are up to the standard and / or the specific content of nutrient elements, and used to indicate whether specific harmful substances (such as specific viruses) Specific substance parameters in excess and / or specified levels, etc.
