される。Next, the bath cleaning operation by the controller 90 will be described with reference to the flowchart of FIG. Now, when the bath cleaning operation switch is turned on by the remote controller 91 (step 101), the controller 90 first switches the first to fifth switching valves 71 to 75 as shown in FIG. The one painted in black is closed) and the circulation circuit 40 for cleaning is communicated (shown by a thick line in the drawing) (step 102). Then, water supply is started from the bath kettle 20 with a hot water supply function to the bathtub 10 through the outflow pipe 21 (step 103). This causes the bath water to overflow and flow into the storage tank 30. When the water level sensor 32 shows a certain level (step 104), the circulation pump 50
Is driven for a certain period of time (steps 105 and 106). As a result, the adsorbent M in the adsorbent storage chamber 33 of the storage tank 30 becomes the first
It flows out together with water from the outflow port 43, enters the lower part of the bath 10 through the cleaning circulation path 40, becomes an upward flow, overflows, and returns to the adsorbent storage chamber 33 of the storage tank 30 again. While this repetition is performed, for the inner and outer surfaces of the bathtub 10,
The adsorbing substance M that rises and overflows comes into contact,
Dust that adheres to the wall surface is physically removed, and the wall is washed by physically and chemically adsorbing and collecting the dust. Of course, the contaminants in the bath water are also adsorbed and removed by the adsorptive substance M. In the case of activated carbon, cloudy bath water is also decolorized. Further, the adsorbent substance M dropped from the bathtub 10 to the apron 11 also cleans the apron 11 cleanly. Therefore, if the apron 11 is used as a washing place, the tiles of the washing place are also cleaned.

に第２流出口44から流出できる。When the certain time has elapsed (step 106), the controller 90 first switches the third switching valve 73 to the second outlet 44 side (step 107), and starts the operation for collecting the adsorptive substance M. After a certain period of time (step 108), the fourth
The switching valve 74 is also opened (step 109), and the adsorptive substance M is collected in the adsorptive substance storage chamber 33 of the storage tank 30 also via the sub path 60. The adsorbent substance M that has returned to the adsorbent substance storage chamber 33 of the storage tank 30 cannot flow out because the first outlet port 43 is closed. Water can pass through the filter 31 into the second chamber 34 and out through the second outlet 44.

When a certain period of time has passed (step 112), the fourth switching valve 74 is closed and the drainage is terminated. Further, the first switching valve 71 is switched to the return pipe 22 side so that the bath operation can be performed (step
113). With this, the bath cleaning operation is completed.

い。In the above, the collection of the adsorptive substance M to the storage tank 30 may be alternately repeated by using the cleaning circulation path 40 and the auxiliary path 60. Further, although the recovered water of the adsorptive substance M remains in the storage layer 30 in the above, if a sterilizing agent injector is attached to the storage tank 30, the growth of bacteria can be suppressed. Of course, the recovered water in the storage tank 30 may also be drained. Further, in the above, confirmation of completion of the collection of the adsorptive substance M may be performed by providing a turbidity sensor at the inlet of the storage tank 30.

It is possible to effectively clean the inner and outer surfaces of the bath by coming into contact with the peripheral wall surface and the outer peripheral wall surface, physically removing adhered scales, etc., and physically and chemically adsorbing them. In addition, the apron around the bathtub where the overflow water falls and the washing area can be cleaned at the same time. Of course, the adsorptive substance adsorbs and cleans the dirt in the bath water.

また吸着性物質は回収して再使用できるようになされ
ているので、非常に便利で経済的である。Further, since the adsorptive substance can be recovered and reused, it is very convenient and economical.
