Electrical motor 1 continues normal operation, the hanging basket 7 of changing one's clothes is up, when being up to upper limit position, because the position-limiting action of framework 8, the hoisting force that promotes the hanging basket of changing one's clothes strengthens, the up spring of up push rod 43 compressions, withstand upper stroke switch 432 until U type positioning plate 42, upper stroke switch 432 disconnects, electrical motor 1 outage, and the hanging basket 7 of changing one's clothes stops to the top.
When hanging basket up the time, upper stroke switch 432 disconnects lower stroke switch 442 closures.If this moment, electrical motor 1 sent positive electricity, because upper stroke switch 432 disconnects, the 1st diode 435 is oppositely obstructed, and electric current can not flow through, and electrical motor 1 is inoperative.So this moment, electrical motor 1 can only send negative electricity, electric current is through lower stroke switch the 442, the 1st diode 435, and electrical motor 1 starts.After the hanging basket 7 of changing one's clothes begins to descend, up push rod 43 contacts with U type positioning plate 42, up spring 434 has certain compression but does not open upper stroke switch 432, be upper stroke switch 432 closures, electric current is through upper stroke switch 432, lower stroke switch 442, electrical motor 1 normal operation, make the hanging basket 7 of changing one's clothes continue operation downwards, when the hanging basket 7 of changing one's clothes arrives ground, the gravity of hanging basket 7 of changing one's clothes no longer is added on the spool 3, up push rod 43 leaves U type positioning plate 42, and descending push rod 44 contacts with U type positioning plate 44, and compresses descending spring 444, disconnect until lower stroke switch 442, this moment, the hanging basket 7 of changing one's clothes was parked on the ground because 445 pairs of the 2nd diodes are reverse obstructed, and electrical motor 1 shuts down.
Because it is bigger to promote the power of the hanging basket 7 of changing one's clothes; therefore can make the stiffness coefficient of the stiffness coefficient of up spring 433 greater than descending spring 443; thereby prevent that gravity protector 4 from making electrical motor 1 quit work prematurely, this also be convenient to control change one's clothes hanging basket 7 be parked in the top particular location.
As shown in Figure 5, be the circuit control principle figure among another embodiment of the utility model.Wherein, between first node A and Section Point B, the 1st diode 435 is connected with the normally closed contact of upper stroke switch 432, and the anode of the 1st diode 435 is connected with first node A; And between first node A and Section Point B, the 2nd diode 445 is connected with the normally closed contact of lower stroke switch 442, and the negative electrode of the 2nd diode 445 is connected with first node A.Series connected the 1st diode 435 and upper stroke switch 432 and series connected the 2nd diode 445 and lower stroke switch 442, in parallel between first node A and Section Point B.First node A is connected with a direct-flow input end of electrical motor 1, and electrical motor 1 can send positive electricity or send negative electricity.Section Point B is connected with the zero line of electrical motor 1 and ground connection.
Change one's clothes hanging basket 7 below the time, upper stroke switch 432 closures, lower stroke switch 442 disconnects, if this moment, electrical motor 1 sent positive electricity, electric current is through the 1st diode 435, upper stroke switch 432 ground connection then, electrical motor 1 can start up.If this moment, electrical motor 1 sent negative electricity, the 1st diode 435 is oppositely obstructed, and the 2nd diode 445 is communicated with but lower stroke switch 442 disconnects the motor fail to start.When the hanging basket 7 of changing one's clothes runs to the top, be subjected to the restriction of framework, the up spring 434 of up push rod 43 compressions, upper stroke switch 432 disconnects, and electrical motor 1 is out of service.
Change one's clothes hanging basket 7 up the time, and upper stroke switch 432 disconnects, lower stroke switch 442 closures, if electrical motor 1 send negative electricity, to ground wire, motor starting moves the hanging basket 7 of changing one's clothes downwards to electric current through the 2nd diode 445, lower stroke switch 442.If this moment, electrical motor 1 sent positive electricity, the 1st diode 435 is communicated with, but upper stroke switch 432 disconnections, the 2nd diode 445 is oppositely obstructed, so electrical motor 1 fail to start, and the hanging basket 7 of changing one's clothes is out of service.
