PURPOSE:To perform both of water draining and washing of a bath tub in accordance with various shapes and configuration thereof by a method wherein, the bath tub consists of a cover plate which fits and blocks and opening part at a recess of a housing openably in liquid tight manner by the pushing up action of a washing water injection mechanism, and water from a water feed system is made to fill the tub in conjunction with the action of a water level sensor. CONSTITUTION:By opening a water drain port 33, the water in the bath tub 26 is drained out, and when the water level reaches a preset level, it is detected by a level sensor 34. Based upon the level detection signal from the sensor 34, and a water pressure switch 35 being turned ON, by the instruction from a controller 36, valves 37 and 40 of a water supply system 31 and washing water system 41 are opened and water is supplied from a running tap water system 38, and also, together with a cleaning liquid from a cleaning liquid bottle 39. The cleaning liquid mixed at an injector is supplied to a feed part 3, functioning also as a sliding port 3 of a housing 1, through a piping 29. A washing water injection mechanism 8 is pushed up by a preset stroke amount and is held at the set position, however, coincident with the pushing up action of the washing water injection mechanism 8, the washing liquid is injected against the inside walls of the bath tub 26 from each of nozzles 12, 12' and 12'', 12'''. |
