and when the last time of the machine halt is smaller than the next time of the machine halt, judging that the storage articles are added in the storage room.
The load (i.e. the stored article) is exemplified by a refrigerator, and since the load can store cold, when the refrigerator is stopped, the temperature of the refrigerator is raised, the load is equivalent to a cold source, when the load is put into the refrigerator, the heat load is increased, and the refrigerator returns to Wen Bianman, and at the moment t occurs 0 ＜t 1 Is the case in (2); after the load is taken out, the heat load is reduced, and the refrigeratorThe tempering time becomes fast correspondingly, so t occurs 0 ＞t 1 Is the case in (a).
In the embodiment of the invention, the storage and the taking of the stored articles of the refrigerator can be determined by judging the increase and the decrease of the machine halt time, and the basis can be provided for the article monitoring of the refrigerator.
Optionally, the controller is further configured to:
when the refrigerator door is not opened before the compressor enters the next stop, judging whether the gear of the refrigerator is adjusted before the compressor enters the next stop;
if yes, the rotating speed of the compressor is adjusted according to the gear; if not, waiting for the next stop of the compressor and recording the next stop time of the compressor;
and adjusting the rotating speed of the compressor after the next startup according to the last shutdown time and the next shutdown time.
