<p>PROBLEM TO BE SOLVED: To provide the function of cleaning a washing nozzle. SOLUTION: A stopping lever 53 consisting of arm parts 63 and 64 is pivoted by a shaft 69 so as to turn freely. A round protruding part 54 is formed at the tip of the arm part 64. A water sending tube 37 is pressed to the side of a receiving part 60 by a press part 69 formed at one end of the arm part 63 and the flow passage is thus blocked. On occasions of cleaning a washing nozzle 16, a tank 15 is pulled out. There an engaging concave part 56 agrees with a through hole 57 and the round protruding part 54 engages with the engaging recess 56. Then the arm part 63 of the stopping lever 53 is turned counterclockwise by the elastic force of the water sending tube 37 which has been pressed. The channel of the water sending tube 37 which has been blocked by the press part 69 of the arm part 63 is thus released and the washing nozzle 16 is cleaned by the washing water sent through the water sending tube 37.</p> |
