When the cleaning process is completed, the process proceeds to a rinsing process in step 107. The operation sequence of the rinsing step is the same as that of the cleaning step, and the rinsing operation is repeated a predetermined number of times as in the first embodiment. After rinsing a predetermined number of times and performing the last drainage, a drying operation is performed, and a series of cleaning operations is completed. The user discharges the drainage stored in the drainage tank 17 to the outside. The second body 38 is a joint between the water supply tank connector 13 and the water supply pipe connector 14 and a joint between the drainage tank connector 18 and the water distribution pipe connector 19.
Since water can be separated from the first main body, when water supply and drainage work is performed, only the second main body needs to be moved and brought to an external water supply or drainage location to supply or drain water. Since the second main body has a structure mainly including a water supply tank and a drainage tank, the second main body can be configured to be small and lightweight, and work such as movement is easy. Therefore, the installation location of the first main body can be freely selected without being affected by the water supply and drainage facilities. Further, since the first main body 37 does not have a water supply tank or a drainage tank, the shape of the main body can be reduced, so that the degree of freedom in selecting an installation location is large.

The work for supplying water to the water supply tank 12 may be performed from the water supply port 23 of the tank, but the second main body 38 is brought to the vicinity of the sink and the hose 53 for supplying water from the water supply / drain hose accommodating section 61 is provided.
