PROBLEM TO BE SOLVED: To provide a wiper washer control device which can efficiently spray a washer liquid to a wiping face of window shield glass by preventing the adhesion of a contact point of a relay by an inexpensive constitution.SOLUTION: A wiper washer control device includes: a relay circuit 34 including relays RA, RB which are connected to a washer motor M for injecting washer liquids from both sides in a turning direction of wiper arms which reciprocate and turn between a lower inverting position and an upper inverting position, and switch directions for injecting the washer liquids by a preset drive signal; a cam switch 32 which is arranged at a cam interlocked with the rotation of a wiper motor WM for turning the wiper arms, set so as to correspond to turning positions of the wiper arms, and outputs a signal which is set so that an on-time of the relays continues for a prescribed time or longer as the drive signal; and a washer switch wSW which is connected to the relay circuit 34, and drives the washer motor M.

    【課題】安価な構成でリレーの接点の熔着を防止してウィンドシールドガラスの払拭面に効率よくウォッシャ液を噴射可能なワイパ・ウォッシャ制御装置を提供することを目的とする。【解決手段】下反転位置と上反転位置との間で往復回動されるワイパアームの回動方向両側からウォッシャ液を噴射するためのウォッシャモータMに接続され、予め定めた駆動信号によってウォッシャ液を噴射する方向を切り換えるためのリレーRA、RBを含むリレー回路34と、ワイパアームを回動させるワイパモータWMの回転に連動したカムに設けられたスイッチであって、ワイパアームの回動位置に応じて設定されると共に、リレーのオン時間が所定時間以上継続するように設定された信号を駆動信号として出力するカムスイッチ32と、リレー回路34に接続された、ウォッシャモータMを駆動するためのウォッシャスイッチwSWと、を含む。【選択図】図1
