For example, in the case where the bubble generating portion 72 is of the pump type, the pump can be driven to move the nozzle piston so that the medicine 70a is foamed by the mesh member provided to the ejection opening. In FIG. 3, the foam-formed medicine is discharged from the discharge port 8 together with the washing water through the water supply pipe 30, but the present invention is not limited thereto, and the foamed drug may be discharged from other discharge ports (not shown). The toilet unit 2 is directly supplied. In addition, the foam generating portion 72 is not provided in the medicine input portion 7, but is provided in the ejection port 8, and the washing water is mixed with the medicine 70a introduced from the medicine input portion 7 in the water supply pipe 30, and then the discharge port 8 is formed. It is foamy and spits out. Further, a mixing device in which fine bubbles are mixed may be provided on the downstream side of the water supply pipe 30, and the washing water containing bubbles and the chemical 70a may be discharged to the toilet portion 2.

The tub body 2b is provided on the outer circumference of the toilet portion 2, and a water supply and drainage cover portion 13 (see FIGS. 1 and 2) is disposed behind the toilet body 10, and the water supply portion 3 and the medicine input portion are housed in the water supply and drainage cover portion 13. 7. The inverting water gate portion 50 or the like constituting the drain portion 5. Further, the water supply unit 3 may be provided in the water supply and drainage cover portion 13 as described above, or may be provided in a wall surface (not shown).

The drain portion 5 includes a drain passage 20 that is formed to extend from the toilet portion 2, and an inversion water gate portion 50 that is a bellows-shaped hollow tube. The reversing water gate portion 50 is formed of rubber or a soft resin, and the one end 50b is connected to the drain passage 20, and the other end 50a is a free end. On the other end 50a side of the inversion water gate portion 50, the electric motor M (refer to Figs. 2 and 3) can be arbitrarily reversed in the vertical direction. The driving source of the motor M and the power source for driving the cleaning switch 6 can be made the same. The reverse water gate portion 50 is covered with a casing 52, and an opening portion 52a is formed on the floor surface side of the casing 52, and the floor side drain pipe 51 connected to the sewage pipe (not shown) is connected to the one opening portion 52a. The casing 52 is preferably a structure that is airtight in order to prevent odor leakage from a sewage pipe (not shown). When the other side end 50a side is located above, as shown in FIG. 1(a) or the like, the water shut-off water shutoff portion 50 is a water-sealing state in which the drain water in the toilet portion 2 is blocked; (b) When the other end 50a side is located below, the washing water in the toilet part 2 is discharged.

Fig. 4 is a block diagram showing the configuration of main parts of the toilet apparatus 1. The control unit 4 is configured by a CPU or the like, and controls the water supply unit 3, the medicine input unit 7, and the drain unit 5 by the operation of the washing switch 6 and the detection by the toilet detecting unit 9. The toilet detecting unit 9 is not particularly limited as long as it detects the start of the toilet. For example, the piezoelectric element or the like may be embedded in the toilet seat 11 to detect the configuration in which the user sits on the toilet seat, or may be configured to detect the opening of the toilet cover 12.

Next, referring to Fig. 1, Fig. 2, and Fig. 5, an example of sealing and draining operations during toilet use will be described. In Fig. 1 and Fig. 2, reference numeral 11 denotes a toilet seat, and 12 denotes a toilet lid. In Fig. 1(c), a needle-like line is shown as a foam-like medicament, and this portion will be described later with reference to Fig. 6 . In addition, an example in which the toilet detecting unit 9 detects that the user sits on the toilet seat will be described below. First, the toilet device 1 is in a sealed state in which the washing water is stored in the toilet portion 2 in the standby state (refer to FIG. 1(a)). The other end 50a of the inversion water gate portion 50 is located above, and the water sealing height in the toilet portion 2 at this time is the reference water level L, and is set in accordance with the Japanese building standard method. When the toilet detecting unit 9 detects that the user sits on the toilet seat 11 (S101), the motor M of the reverse water gate unit 50 is driven to slightly tilt the reverse water gate portion 50 between the predetermined time. The reverse water gate portion 50 is rotated downward (refer to S102 and FIG. 1(b)). That is, instead of making the reverse water gate portion 50 down to the other end 50a completely downward as in FIG. 2(b), the reverse water gate portion 50 is moved slightly downward so that the water level of the toilet portion 2 is self-contained. When the water level L is lowered to L1, the washing water is allowed to overflow from the other end 50a. Then, the reverse water gate portion 50 is rotated again so that the other end 50a of the reverse water gate portion 50 faces upward (S103). Thereby, the washing water in the toilet portion 2 is discharged only by the predetermined amount (L-L1) (refer to FIGS. 1(b) and (c)), and the water level of the toilet portion 2 is lowered to L1. Specifically, the user sits in front of the water level at the "L" position. If it is detected that the user sits on the toilet seat, it is regarded as going to the toilet, so that the height of the sealing water is lowered to "L1". The height of the sealing water is maintained at this L1 before the washing switch 6 is operated. In this way, since the water level of the toilet portion 2 is lowered from the reference water level L to L1 as soon as the user sits down, the splashing of the water in the toilet (so-called splash back splashing) can be prevented, and the water can be comfortably use.

When the cleaning switch 6 is turned ON (S104), the washing water is supplied from the water supply unit 3 for a predetermined time (S105), and the water level of the toilet portion 2 is raised again to the height L1 of the self-sealing water before draining (refer to the figure). 2(a)). After that, the motor M that drives the reverse water gate unit 50 causes the other end 50a to face downward, receives the supply of the washing water from the water supply unit 3, and performs drainage washing operation (refer to S106, FIG. 2(b)). At this time, the water level in the toilet portion 2 rises from L1 to L, and in order to wash the toilet portion 2 and carry the dirt, sufficient washing water is sealed, so that the cleaning power or the dirt conveying performance can be prevented from being lowered.

When the draining operation is completed, the motor M that drives the reverse water gate unit 50 is directed upward, and the supply of the washing water is received from the water supply unit 3, and the water sealing operation is performed (refer to S107, FIG. 2 ( c)). The height of the sealing water at this time is set to be set to L according to the Japanese Building Standard Law. In this way, after the drainage, the sealing position according to the Japanese Building Standard Law is ensured, so the law can be followed and the odor from the sewage pipe can be cut off.

In the above, although the toilet detecting unit 9 detects an example in which the water level of the toilet portion 2 is lowered by sitting on the toilet seat, it is also possible to cause the toilet detecting portion 9 to detect the opening of the toilet cover 12 as described above. In order to detect the composition of the beginning of the toilet. In this case, when the opening of the toilet lid 12 is detected, the water level of the toilet portion 2 is lowered when the user is in the standing state or the like, so that splashing of urine or the like can be prevented. Therefore, it is possible to prevent the urine or the like from splashing on the wall surface or the floor surface of the toilet apparatus 1, and it is possible to contribute to the reduction in the number of cleanings. By opening the toilet lid 12 (lifting the toilet lid 12), the water level is lowered, and the water level is first raised when the drain is washed, and then the drain is washed, so that the drain can be washed with a sufficient amount of water.

Next, referring to Fig. 1, Fig. 2 and Fig. 6, other examples of sealing and draining operations during toilet use will be described. In this example, the point where the water level of the toilet portion 2 is lowered and the medicine 70a is put into the toilet portion 2 is different from the above example. Here, although the toilet detecting unit 9 detects an example in which the user sits on the toilet seat, the present invention is not limited thereto, and may be configured to detect the opening of the toilet cover 12. In addition, the description of the same portions as the above examples will be omitted, and the differences will be mainly described.

First, the toilet device 1, in this example, is also in a sealed state in which the washing water is stored in the toilet portion 2 in the standby state (refer to Fig. 1 (a)). When the toilet detecting unit 9 detects that the user sits on the toilet seat 11 (S201), the motor M of the reverse water gate unit 50 is driven to slightly tilt the reverse water gate portion 50 between the predetermined time. The reverse water gate unit 50 is rotated downward (refer to S202 and FIG. 1(b)), and the washing water is allowed to overflow from the other end 50a. Then, the reverse water gate portion 50 is rotated again so that the other end 50a of the reverse water gate portion 50 faces upward (S203). Thereby, the water level of the toilet portion 2 is lowered to L1.

At this time, the medicine 70a is introduced from the medicine input unit 7 (refer to S204, FIG. 1(c)). Thereby, not only the water level of the toilet portion 2 is lowered, but also the injection of the medicine 70a can more effectively prevent splashing of water during the toilet (so-called splashback). In other words, when the medicine 70a to be supplied is a detergent containing a surfactant, it can be foamed by dropping of dirt, urine, or the like into the toilet portion 2, and the foam becomes a buffer portion and is further reduced. Splash of dirt or urine. Here, in order to promote the foaming of the medicine 70a which is put in the toilet part 2, the washing water may be swirled in the toilet portion 2 at the time of input or after the injection, and may be stirred for several seconds.

The drug 70a to be introduced here is not limited to a liquid state, and may be made foamy by the foam generating portion 72. In this case, the flushing of the dirt or urine or the like is not caused by dropping into the toilet portion 2, and the foam is allowed to flow into the water surface of the toilet portion 2 as indicated by the dotted line in Fig. 1(c), so that the toilet can be started. In the initial stage, the splash of dirt, urine, etc. is surely suppressed.

When the cleaning switch 6 is turned ON (S205), the washing water is supplied for a predetermined time (S206), and the water level of the toilet portion 2 is raised again to the height L1 of the self-sealing water before draining (refer to FIG. 2(a). ). After that, the motor M that drives the reverse water gate unit 50 causes the other end 50a to face downward, receives the supply of the washing water from the water supply unit 3, and performs drainage washing operation (refer to S207 and FIG. 2(b)). At this time, not only the sufficient amount of water for washing but also the medicine 70a is introduced into the toilet portion 2, so that the washing power of the toilet portion 2 can be improved.

After the completion of the drain cleaning operation, the motor M that drives the reverse water gate unit 50 causes the other end 50a to face upward and receives the supply of the washing water from the water supply unit 3, and performs a water sealing operation (refer to S208 and FIG. 2(c)). In this way, after the drainage, the sealing position according to the Japanese Building Standard Law is ensured, so the law can be followed and the odor from the sewage pipe can be cut off.

Although the example in which the water level of the toilet portion 2 is lowered and the medicine 70a is put into the toilet portion 2 has been described above, the viscosity adjusting agent 73a stored in the adjusting agent tank 73 may be charged at this point in time. In this case, the viscosity of the stored washing water is increased by the viscosity adjusting agent 73a, so that splashing of dirt, urine, or the like can be further reduced. In this case, the viscosity adjusting agent 73a that has been put into the toilet portion 2 can be dissolved in the washing water, and the washing water can be swirled in the toilet portion 2 for a few seconds at the time of input or after being charged, and stirred.

The shape, configuration, and the like of the toilet device 1 are not limited to the above. For example, the toilet body 10 may be a resin molded product or a ceramic device. The washing switch 6 can be disposed on a remote controller mounted on the wall surface or in the toilet body 10. Further, the toilet device 1 may include a washing nozzle for washing and drying a part of the human body, a drying function, a heating function of the toilet seat, and an armrest. In addition, when water is sealed after the toilet, one of the water mixed with the gas or the detergent mixed with the gas may be selected as the washing water, and the toilet portion 2 is spouted and sealed.
