It is also preferable that control is performed such that the amount of bubbles generated in the power saving operation state is larger than the amount of bubbles generated in the state. FIG. 3 shows the generation of bubbles 21 at the time of detection of entry into the room in the normal operation state and the generation of bubbles 21 at the time of transition from the normal operation state to the power saving operation state. In this way, by setting the bubble generation time to be larger when in the power saving operation state than in the normal operation state and controlling so that the amount of foam generation at one time becomes larger, it is possible to achieve a power saving operation state in which the toilet is rarely used. At a certain time, the surface of the toilet 2 and the foam 21 can be brought into contact with each other for a long period of time to obtain high cleaning and antifouling effects.

Further, if the automatic foam generation mode is selected, the generation and supply of the foam 21 are started by the operation of the toilet foam generator 1 at predetermined foam generation time intervals, and the operation is stopped after the predetermined foam generation time has elapsed. It is also preferable that the control is performed so that, when the automatic bubble generation mode is selected, a plurality of bubble generation time intervals can be selected by a bubble generation time interval operation key (not shown) provided in the operating means. It is also preferable to be able to switch the bubble generation time interval between the normal operation state and the power saving operation state by selecting an arbitrary bubble generation time interval. FIG. 4 shows a case in which the bubble generation time interval in the normal operation state is set to be smaller than that in the power saving operation state, but in the normal operation state in which the toilet is frequently used as described above. By frequently generating the bubbles 21 and keeping them in contact with the surface of the toilet bowl 2 for a long time, a high cleaning and antifouling effect can be obtained.

In the automatic bubble generation mode as described above, the automatic generation of bubbles is controlled in such a manner that the generation of bubbles 21, the start and stop of supply, are automatically repeated at predetermined time intervals. By operating the foam generation amount operation key and the foam generation time interval operation key provided in the operating means at the time of mode selection, as shown in FIG. 5, the foam generation amount and the foam generation amount in the normal operation state and the power saving operation state. It is also preferable to be able to switch the generation time interval, and by making these settings appropriate, high cleaning and antifouling effects can be obtained.

Further, as shown in FIG. 6, when the user selects the automatic bubble generation mode by operating the bubble generation mode switching key, the toilet lid / toilet seat position detection sensor opens the toilet lid 5 from the closed state to the open state. The power supply / control unit 8 causes the foam pump 19 of the toilet foam generator 1 to move the bubbles in the tank 17 at the time of detecting the shift to the closed state and at the time of detecting the shift from the open state to the closed state. It is also preferable to send air to the generation unit 18 to generate bubbles 21 in the bubble generation liquid 16 and supply the bubbles 21 into the toilet 2 through the bubble supply path unit 20 and automatically stop after a predetermined bubble generation time has elapsed. Is.

Generally, when the toilet lid 5 is opened, it is just before using the toilet, and by supplying the bubbles 21 at this time, it is possible to prevent the splashing of the accumulated water during defecation. Moreover, since the toilet lid 5 is generally closed immediately after using the toilet, the foam 21 is supplied at this point to keep the surface of the toilet bowl 2 in contact with the foam 21 for a long period of time, which has a high cleaning and antifouling effect. Can be obtained.
