The invention provides a hidden automatic-cleaning intelligent toilet. The hidden automatic-cleaning intelligent toilet comprises a toilet body external machine, a toilet unit and a sewage dischargingunit, the toilet body external machine is embedded into a concaved wall and internally provided with a pressurizing water tank, a steam unit, a cleaning unit and an intelligent control unit, the toilet unit is provided with a connecting rotating shaft which is connected with the inner side of the toilet body external machine, the pressurizing water tank is communicated with the toilet unit through a shaft pipeline, the rotating shaft is connected with the control unit, the toilet unit is arranged in the concaved position of the toilet body external machine and installed above the sewage discharging unit, the toilet unit is opened after the shaft is rotated by 90 degrees and then extends out, and the toilet unit rotates to be closed to be flush with the wall perpendicularly; the sewage discharging unit and the toilet unit are closed and the connected through a butt joint opening. The intelligent toilet is a hidden toilet, systematic optimization is conducted on the mode that accordingto a traditional hidden water tank toilet, a hidden water tank is installed first, and then a toilet body is installed, the change from two-stage installation to one-time installation at the late stage is safer and more convenient, the toilet is hidden in a wall or is made upright to be installed on the wall, in this way, the space for installation and usage is saved, and a bathroom is convenientto manage and neater. The function of automatic cleaning is realized, during storage, a seat is cleaned, and therefore sanitation and cleanliness are guaranteed when the seat is used again; an intelligent dredging device is further arranged, a gas auxiliary dredging function is further set, and therefore no blocking occurs.
