An agent pump 36 is provided in the agent supply path, and a surfactant can be supplied to the liquid storage unit 32 via the agent supply port 322. The surfactant of this embodiment is constituted by a detergent. By supplying the surfactant and water to the liquid storage unit 32, the surfactant aqueous solution can be stored in the liquid storage unit 32. Thereby, the bubble generated from the bubble generating body 4 can be made difficult to burst.

  The foam generator 4 is arranged inside the liquid storage unit 32. When the surfactant aqueous solution is stored in the liquid storage unit 32, the foam generator 4 is immersed in the surfactant aqueous solution and generates bubbles in the surfactant aqueous solution. . The foam generating body 4 of the present embodiment is composed of foam stone 40, for example. Foam stone 40 of the present embodiment is a porous stone, and examples thereof include perlite (pearl stone) and pumice. As shown in FIG. 3, the foamed stone 40 may be constituted by one stone or may be constituted by an aggregate of a large number of stones.

The air delivery unit 34 includes an air pipe 341 and an air pump 342 (FIG. 2) connected to the air pipe 341, and the air sent from the air pump 342 passes through the air pipe 341 to the inside of the foam stone 40. Discharged.

  A foam supply opening 51 is formed in the partition part 5. The bubble supply opening 51 passes through the partition part 5 and allows the liquid storage part 32 and the communication part 31 to pass through. The foam supply opening 51 is formed at the center of the partition 5 and is disposed above the foam stone 40. In other words, the bubble supply opening 51 and the bubble generator 4 overlap each other when viewed from above (hereinafter sometimes referred to as a plan view). In normal times, the level of the aqueous surfactant solution stored in the liquid storage unit 32 is the same as or higher than that of the partition unit 5 (may be the same height as the lower end of the inner surface of the water supply pipe). Many). Therefore, the foam generated from the foam stone 40 rises in the surfactant aqueous solution, passes through the foam supply opening 51, and is exposed in the communication part 31.

The air intake unit 62 is configured to supply air (air) to the water supply channel 2, and thereby, air can be included in the cleaning water and the foam. In the air intake part 62, at the connection part with the mixing part 61, the inclination angle α of the air flow direction with respect to the flow direction of the wash water is set to 90 ° or more (preferably 135 ° or more). An air pump 63 is connected to the air intake part 62, and air can be forcibly supplied to the mixing part 61.

  The air supplied to the mixing unit 61 is mixed with the cleaning water and the bubbles flowing through the mixing unit 61 and flows along with the cleaning water. Then, the washing water and bubbles mixed with air increase in flow rate in the water supply channel 2 due to an increase in volume, and the amount of air contained in the bubbles increases. Therefore, according to this configuration, it becomes possible to supply bubbles with a larger amount of air into the bowl 11.

  As shown in FIG. 5, the toilet device includes a control unit 8 that controls various pumps (agent pump 36 and air pumps 342 and 63), the electromagnetic valve 23, and the driving device 162 of the drain trap 16. For example, the control unit 8 can generate bubbles by driving the air pumps 342 and 63 and the agent pump 36, or supply water to the bowl surface 110 by opening the electromagnetic valve 23.

  The toilet device configured as described above operates as follows, for example.

  When the user enters the toilet room and the toilet seat 13 is opened manually or by an instruction from a remote controller, the control unit 8 drives the air pump 342 to send air into the foam stone 40 to create bubbles on the surface of the foam stone 40. generate. Then, the foam generated on the surface of the foam stone 40 accumulates in the communication part 31 through the foam supply opening 51. At this time, the control unit 8 drives the agent pump 36 to supply a certain amount of detergent to the liquid storage unit 32. It should be noted that the detergent may be supplied in a constant amount for each use, or may be supplied in a predetermined amount every predetermined number of times.

  The control unit 8 drives the air pump 342, and when a predetermined time has elapsed, opens the electromagnetic valve 23 and causes the cleaning water to flow through the water supply channel 2. Then, the washing water flows into the communication part 31 via the inflow port 311 and flows out from the outflow port 312 together with the accumulated bubbles, whereby a large amount of bubbles flows through the water supply channel 2.

  Next, the cleaning water accompanied by bubbles flows into the air supply unit 6. The control unit 8 drives the air pump 63 of the air intake unit 62 to take in air into the cleaning water. Then, a large amount of foam that has flowed into the air supply unit 6 contains more air and is supplied into the bowl 11 in this state.

  A large amount of foam and washing water supplied into the bowl 11 are stored in the bowl 11 while swirling along the bowl surface 110. The washing water stored inside the bowl 11 becomes sealed water, and a large amount of foam is deposited on the sealed water surface to form a layer.

  The toilet device according to the present embodiment suppresses the urine from splashing back and splashing on the sealing surface due to the thick foam cushion effect even if the urine falls down on the sealing surface vigorously by the user pissing in this state. can do.

  Thereafter, the control unit 8 drives the driving device 162 of the drain trap 16 to drain the sealed water to the drain pipe 71. After a certain period of time has elapsed after draining, the control unit 8 drives the driving device 162 to switch the tip of the trap cylinder 161 to face upward, and in this state, supply cleaning water and a large amount of foam into the bowl 11. .

  Since the foam stored in the bowl 11 contains the surfactant, the state of being on the sealed surface is maintained for about 3 hours. Therefore, when the time until the next use is less than 3 hours, the foam remains in the bowl 11, so that it is not necessary to perform control to supply the foam into the bowl 11 as the toilet seat 13 is opened.
