Permanent magnet), an electromagnetic structure 24 (preferably electromagnetic coil), coil are fixed in the position of respective magnet structure 23 on lower cover 25
Two end electrodes can accordingly be switched, and coil is powered reaches the mesh that control pin 22 is run by attracting and repelling permanent magnet
's.Compressor from twin-tub pattern switching into single cylinder run when, coil 24 is made to be powered, allows 24 electromagnetic force polarity of coil with permanent magnet 23
On the contrary, then coil 24 is identical with 23 opposite polarity of permanent magnet, identical charges repel each other, and permanent magnet 23 is subject to coil 24 to repel, and promotes pin
22 downward 20 afterbody of slide plate operations make the lower slide plate 20 of the locking of pin 22, and lower slide plate 20 can not do followability movement with lower roller 19,
Lower cylinder 18 unloads, and without compression, compressor enters single cylinder pattern and run.Compressor is from single cylinder pattern switching into twin-tub
During operation, 24 electromagnetism force direction of switching coil makes 24 electromagnetic force polarity of coil identical with permanent magnet 23, then coil 24 and permanent magnet
For 23 opposite polarity on the contrary, there is a natural attraction between the sexes, permanent magnet 23 drives pin 22 from lower 20 afterbody of slide plate to coil under the attraction of coil 24
24 directions are run, and are come out from the second pin hole 27 of lower 20 afterbody of slide plate, pin 22 is separated with lower slide plate 20 so that lower slide plate 20
It is contacted with lower roller 19 and does followability movement with lower roller 19, lower cylinder 18 loads after compressor start, with upper cylinder 14 1
Sample is normally compressed, and forms the twin-tub pattern of conventional duplex cylinder compressor operation.Complete the transfiguration adjusting control of compressor.
For those skilled in the art it is easily understood that on the premise of not conflicting, above-mentioned each advantageous manner can be free
Ground combination, superposition.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.With
Only it is the preferred embodiment of the present invention described in upper, it is noted that for those skilled in the art, not
