It is interior, that is to say, that when pattern switching, the pumping work of aspiration pump 40 has only carried out a part.So, the pumping after pattern switching
The remaining working time of pump 40 can be determined according to each sucking rate of aspiration pump 40.Such as: under high effective model, pumping
The speed of exhaust of pump 40 is 1L/s, and under the silent mode, the speed of exhaust of aspiration pump 40 is 0.5L/s, each pumping of aspiration pump 40
Tolerance is 100L.That is, under normal circumstances, the aspiration pump 40 under high effective model will continue working 100s, and silent mode
Under, it needs to continue working 200s.If at a time, aspiration pump 40 is switched to silent mode by high effective model, when pattern switching,
Aspiration pump 40 has worked 50s, i.e. the gas that has extracted 50L of aspiration pump 40.So, after pattern switching, aspiration pump
40 should also be evacuated 100s (gas for namely also needing to extract 50L) under the silent mode, to guarantee that each sucking rate is
100L.Certainly, above-mentioned data can change according to the concrete condition of refrigerating device and aspiration pump 40, go out in the example above
Existing data are merely for convenience of the working principle of the aspiration pump 40 of detailed description the present embodiment, should not be understood as to structure of the present invention
