The present invention relates to an integrated motor pump for a washer liquid, and more specifically, to an integrated motor pump for a washer liquid, having a resistance way or a capacitance way-level sensor integrally mounted thereon, the level sensor detecting a remaining amount of washer liquid stored in a washer liquid tank to output a detection signal, thereby allowing a driver to check the remaining amount of the washer liquid through a gauge or an alarm and replenish new washer liquid in case of a shortage. When two electrodes of the resistance way-level sensor are submerged under a medium, a microcurrent flows through the medium between the two electrodes such that a transistor (TR) is driven using a signal of the microcurrent to construct a circuit on a printed circuit board (PCB) to allow the remaining amount of the washer liquid to be checked through the alarm or the gauge. In addition, an erroneous operation caused by the corrosion of a terminal due to the washer liquid and accumulated scale and erroneous operation with respect to a water repellent washer liquid can be prevented. Also, the liquid level can be detected with a difference between lengths of electrode rod 1 and electrode rod 2 of the resistance way-level sensor. Furthermore, a low liquid level can be controlled by adjusting angles and the lengths of electrode rod 1 and electrode rod 2. As such, the circuit is constructed on the PCB to allow the remaining amount of the washer liquid to be checked through the alarm and the gauge after reading a capacitance value of the medium between the two electrodes by a capacitance element such that the current is shut off when there is a high liquid level and is allowed to flow when there is a low liquid level. |
