PROBLEM TO BE SOLVED: To provide a car washing machine, which is configured to execute water drainage operation by introducing compressed air into a water path after car washing is finished, and a water drainage control method, which can surely achieve the water drainage operation at low costs without scattering water around.SOLUTION: A car washing machine is equipped with a spray nozzle for spraying washing water upward and a water path for feeding the washing water to the spray nozzle, in which an electromagnetic valve and a compressed air introducing portion for introducing compressed air are provided in the water path, which is configured to perform as water drainage operation first water drainage operation EX1 by which opening/closing control by which the electromagnetic valve is opened for first time T1 and closed for second time T2 is repeatedly performed plural times, and second water drainage operation EX2 by which opening control for the electromagnetic valve is continued for third time T3 longer than the total of the first time T1 and the second time T2, following the first water drainage operation.SELECTED DRAWING: Figure 4

    【課題】洗車終了後の水経路内に圧縮空気を導入して水抜き操作を実行する洗車機において、周囲に水を飛散せずに水抜き操作を確実に、また、低コストで実現できる洗車機および水抜き制御方法を提供する。【解決手段】上方に向けて洗浄水を噴射する噴射ノズルと該噴射ノズルに洗浄水を送給する水経路を備えた洗車機において、水経路に圧縮空気を導入するための電磁弁と圧縮空気導入部を設け、水抜き操作として、電磁弁を第1の時間T1開放し第2の時間T2閉止する開閉制御を繰り返し複数回行う第1水抜き操作EX1と、第1水抜き操作の後に電磁弁の開放制御を第1の時間T1と第2の時間T2の合計よりも長い第3の時間T3続行する第2水抜き操作EX2を行う構成とした。【選択図】図4
