Microfluidic control detection system and refrigerator

A microfluidic control detection system for a refrigerator, wherein the microfluidic control detection system comprises:

• a microfluidic biochip, comprising an inlet, a suction port, and a detection pool formed inside, where the inlet, the detection pool, and the suction port are sequentially interconnected through microchannels;
• a weighing platform, fixedly set on a support frame, and configured to measure weight of a sample contained in a sample cup placed on it;
• a buffer solution driving device, configured to deliver a predetermined amount of buffer solution matching the weight of the sample to the sample cup, thereby producing a sample solution by mixing the buffer solution with the sample in the sample cup;
• a bracket, configured to move in a controlled manner or an operable manner, driving the sample cup to move to a highest position where the sample liquid in the sample cup can contact the inlet of the microfluidic biochip;
• and
• a detection mechanism, configured to detect the detection pool to obtain predetermined detection parameters of the sample liquid that enters the detection pool through the inlet.
