1. A flow rate control valve having a waterproof function of a driving motor, for transferring a fluid pumped by a water supply pump to a nozzle unit and a nozzle cleaning unit for cleaning the nozzle unit, the flow rate control valve comprising:
at least one housing in which the fluid pumped by the water supply pump is accommodated; and
at least one driving motor configured to change a communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by rotation,
wherein at least one sealing adapter is formed between the at least one housing and the at least one driving motor so as to prevent the fluid from flowing into the at least one driving motor,
wherein the at least one sealing adapter comprises:
a first sealing member, in which a through hole is formed through which rotation shafts of the at least one driving motor pass;
second sealing members into which the rotation shafts passing through the through hole of the first sealing member are inserted and which are rotated by driving of the at least one driving motor, and which have a space portion in which the fluid is configured to be accommodated; and
rotational force transmission members configured to rotate flow rate control members according to rotation of the second sealing members, and
wherein the flow rate control members are coupled to the rotational force transmission members and are configured to change the communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by the rotation.
