In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of anti-dry tap control device of automatic box washer water saving that can overcome above defective.
In order to achieve the above object, the technical scheme that the utility model is taked is, the anti-dry tap control device of a kind of automatic box washer water saving comprises magnetic valve water inlet control tongue tube, magnetic valve stop to supply water tongue tube, anti-dry tap control tongue tube, magnetic valve, main motor A.C. contactor control coil, 1
#, 2
#, 3
#Auxiliary reclay, isolating transformer, its connected mode is: start button is normal makes war and the main motor A.C. contactor end and 3 afterwards in parallel of often making war
#The normally closed some series connection of auxiliary reclay, the other end is connected with main motor A.C. contactor control coil, and then is parallel to the elementary of isolating transformer; 2
#Auxiliary reclay is normal makes war with after magnetic valve is connected, and is parallel to the secondary two ends of isolating transformer again; Magnetic valve stop to supply water tongue tube and 1
#After the series connection of auxiliary reclay control coil, be parallel to the secondary two ends of isolating transformer again; Magnetic valve water inlet control tongue tube and 2
#After another normal parallel connection battle of auxiliary reclay, again with 1
#Normal battle of auxiliary reclay and 2
#After the series connection of auxiliary reclay control coil, be parallel to the secondary two ends of isolating transformer again; Anti-dry tap control tongue tube and 3
#After the series connection of auxiliary reclay control coil, be parallel to the secondary two ends of isolating transformer again.
The beneficial effects of the utility model are: the automaticity height, cost is low, saves the water source.

#Auxiliary reclay, isolating transformer 1, its connected mode is: start button often make war 3 with main motor A.C. contactor often make war 2-1 in parallel after, an end and 3
#Normally closed some 7-1 series connection of auxiliary reclay, the other end is connected with main motor A.C. contactor control coil 2, and then is parallel to the elementary of isolating transformer 1; 2
#Auxiliary reclay is often made war 6-1 with after magnetic valve 4 is connected, and is parallel to the secondary two ends of isolating transformer 1 again; Magnetic valve stop to supply water tongue tube 10 and 1
#After 5 series connection of auxiliary reclay control coil, be parallel to the secondary two ends of isolating transformer 1 again; Magnetic valve water inlet control tongue tube 9 and 2
#After another normal 6-2 parallel connection battle of auxiliary reclay, again with 1
#Auxiliary reclay often make war 5-1 and 2
#After 6 series connection of auxiliary reclay control coil, be parallel to the secondary two ends of isolating transformer 1 again; After anti-dry tap is controlled tongue tube 8 and auxiliary reclay 3 control coils 7 are connected, be parallel to the secondary two ends of isolating transformer 1 again.
Its operation principle is:
1, in the middle of water level drops to spacing some the time, magnetic valve water inlet control tongue tube 9 closures, the magnetic valve tongue tube 10 that stops to supply water disconnects 1
#The auxiliary reclay 5-1 closure of often making war, 2
#6 work of auxiliary reclay control coil, 2
#The auxiliary reclay 6-1 closure of often making war.Magnetic valve 4 energising work, water level rises gradually, when rising to upper limit site 1
#5 energisings of auxiliary reclay control coil, 1
#The normal disconnected 5-1 of making war of auxiliary reclay leaves, and stops to supply water.
2, when anhydrous in the running water pipe or certain reason are cut off the water, water pump draws water and makes water level in the pond drop to the position in minimum site.Anti-dry tap control tongue tube 8 closures, magnetic valve water inlet control tongue tube 9 and the magnetic valve tongue tube 10 that stops to supply water disconnects 3
#Normally closed some 7-1 of auxiliary reclay disconnects, main motor A.C. contactor control coil 2 outages, and water pump quits work.
