This design not only provides an outlet for the steam discharge of the second steam sterilizing device 6 to prevent the sterilized steam from diffusing outward, but also can utilize this part of steam to realize the continuous heating of the liquid in the heat exchange pipe assembly 62, thus significantly improving the sterilizing efficiency of the second steam sterilizing device 6. In addition, the steam subsequently entering the heat exchange tube assembly 62 can also play a role in cleaning the steam cleaning water collecting pipe 65, the upper liquid distribution chamber 621, the heat exchange water pipe 623, the lower liquid collecting chamber 622 and the water discharging pipe 66, so that the self-cleaning of the second steam sterilizing device 6 is facilitated.

Further, as shown in fig. 5, the utility model discloses be equipped with the temperature sensor 69 that is arranged in detecting the liquid temperature in its inner chamber in the lower liquid-collecting chamber 622 or the drain pipe 66 of second steam sterilization device 6 for when the liquid temperature reaches the default to control module 31 send flowing back signal, so that control module 31 control first drainage control valve 15 open.

After adopting above-mentioned technical scheme, control module 31 can in time master the second steam device 6 that kills and disappears the degree to the heating of liquid in its heat exchange tube assembly 62 to liquid that will handle after it heats liquid to the preset temperature value discharges to black water tank 7, need not manual intervention, degree of automation is high, and is favorable to improving the treatment effeciency of second steam device 6 that kills and disappears.

Further, as shown in fig. 2, the utility model discloses be equipped with the level sensor 71 that is used for detecting its box internal liquid level in the black water tank 7 of closestool for when the liquid level reaches the default to control module 31 send flowing back signal, so that control module 31 control second flowing back control valve 16 open.

After adopting above-mentioned technical scheme, control module 31 can in time master the volume that black water tank 7 internal liquid was collected through level sensor 71 to after the water yield in black water tank 7 reached predetermineeing the water volume value, open second drainage control valve 16 and discharge the water in black water tank 7 in order to wash drainage return bend 5, need not manual intervention, degree of automation is high.

Further, referring to fig. 6, the toilet of the present invention further includes a sensor a18 and a sensor B19.

Specifically, the sensor a18 is disposed at a position where the seat 121 of the toilet lid 12 is in open-close movable contact with the toilet bowl 11, and is configured to detect an open-close state of the seat 121 of the toilet lid 12.

Specifically, the sensor B19 is disposed at a position where the cushion cover 122 is in open-close movable contact with the seat ring 121, and is configured to detect an open-close state of the cushion cover 122.

Specifically, the sensor B19 and the sensor a18 are connected to the control module 31, and are configured to send a cleaning start signal to the control module 31 when the seat 121 of the toilet lid 12 and the seat lid 122 are closed and close the toilet bowl 11 at the same time, and send a cleaning stop signal to the control module 31 when any one of the seat 121 or the seat lid 122 is opened.

In practical use, after relieving oneself, a user manually closes the seat ring 121 and the cushion cover 122 of the toilet lid 12 to close the toilet bowl 11, and at this time, the sensor a18 and the sensor B19 simultaneously recognize that the seat ring 121 and the cushion cover 122 are closed in place, and only under the condition, the two will send a start cleaning signal to the control module 31, so that each part of the toilet starts to work to kill and treat excrement through high temperature steam, and the toilet bowl 11 is flushed by steam, and the function of the start control is similar to that of a flushing valve of a traditional toilet. Meanwhile, the utility model can start the steam sterilizing treatment process only after the toilet seat 121 and the seat cover 122 seal the toilet bowl 11, and can also ensure that no steam overflows from the upper opening of the toilet bowl 11 in the treatment process, thus being safer for users.

The utility model discloses the closestool adopts steam to kill and handles the excrement in-process, in case the user manually opens any one in cushion lid 122 or seat ring 121, sensor A18 or sensor B19 send immediately to control module 31 and stop clean signal in order to terminate the steam of closestool and kill the processing procedure.
