These charging circuits 33 are set to charge the lithium ion secondary battery 55 during night hours, for example, from 3 am to 5 am.

このため、水洗式大便器の使用頻度が高い朝の時間帯の前にリチウムイオン二次電池５５を満充電の状態にすることができるため、その後に便器洗浄装置５０が繰り返し駆動されてもリチウムイオン二次電池５５の充電量の不足を招き難くすることができる。このように、リチウムイオン二次電池５５の充電量が下がりすぎてしまうことを防止することができるため、便器洗浄装置５０を確実に駆動することができ、便器洗浄を常に良好に実行することができる。また、夜間の時間帯であるため、安い電気料金でリチウムイオン二次電池５５を充電することができる。   For this reason, since the lithium ion secondary battery 55 can be fully charged before the morning time zone when the flush toilet is used frequently, the lithium ion secondary battery 55 can be recharged even if the toilet cleaning device 50 is repeatedly driven thereafter. Insufficient charge of the ion secondary battery 55 can be prevented. Thus, since it can prevent that the charge amount of the lithium ion secondary battery 55 falls too much, the toilet bowl washing | cleaning apparatus 50 can be driven reliably and toilet bowl washing | cleaning can always be performed favorably. it can. Moreover, since it is a night time zone, the lithium ion secondary battery 55 can be charged with a low electric charge.

局部洗浄装置３１のリモートコントローラー３１Ａは充電回路３３のリチウムイオン第２電池５５への充電をＯＮ−ＯＦＦする充電スイッチを設けている。充電スイッチをＯＮにすることによって、局部洗浄装置３１の充電回路３３がリチウムイオン二次電池５５を充電することができる。このように、この水洗式大便器は、任意にリチウムイオン二次電池５５を充電することができる。   The remote controller 31 </ b> A of the local cleaning device 31 is provided with a charge switch for turning on and off the charging of the lithium ion second battery 55 of the charging circuit 33. By turning on the charging switch, the charging circuit 33 of the local cleaning device 31 can charge the lithium ion secondary battery 55. Thus, this flush toilet bowl can charge the lithium ion secondary battery 55 arbitrarily.

このような構成を有する水洗式大便器は、非停電時は、自動洗浄装置３２、又は局部洗浄装置３１のリモートコントローラー３１Ａに設けられた便器洗浄ボタンを操作することによって、便器洗浄を実行することができる。一方、停電時は、便器洗浄装置５０の操作ボタン５６を操作することによって、便器洗浄を実行することができる。この際、リチウムイオン二次電池５５に蓄えた電気を利用して、便器洗浄装置５０である制御装置５３、リム用開閉弁５１、及びジェット用開閉弁５２が駆動される。リチウムイオン二次電池５５は、便器装置３０である暖房便座２１、局部洗浄装置３１、及び自動洗浄装置３２とは切り離されているため、便器洗浄装置５０の駆動以外に使用されない。このため、リチウムイオン二次電池５５の電気消耗が少なく、停電時でも繰り返し便器洗浄装置５０を駆動することができる。   The flush toilet having such a configuration performs toilet cleaning by operating a toilet cleaning button provided on the automatic cleaning device 32 or the remote controller 31A of the local cleaning device 31 when there is no power failure. Can do. On the other hand, when a power failure occurs, toilet cleaning can be performed by operating the operation button 56 of the toilet cleaning device 50. At this time, using the electricity stored in the lithium ion secondary battery 55, the control device 53, the rim opening / closing valve 51, and the jet opening / closing valve 52, which are the toilet cleaning device 50, are driven. Since the lithium ion secondary battery 55 is separated from the heating toilet seat 21, the local cleaning device 31, and the automatic cleaning device 32, which are the toilet device 30, the lithium ion secondary battery 55 is not used except for driving the toilet cleaning device 50. For this reason, there is little electric consumption of the lithium ion secondary battery 55, and the toilet bowl washing | cleaning apparatus 50 can be driven repeatedly also at the time of a power failure.

したがって、実施例２の水洗式大便器も、停電時に便器洗浄を良好に実行することができる。   Therefore, the flush toilet of Example 2 can also perform toilet flushing well during a power failure.
