Referring to fig. 1 to 5, a self-cleaning bathtub comprises a body 10, wherein the body 10 is provided with a water inlet device 20 and a water outlet device 30, and further comprises a switching control valve 40, a cover 50 and a cleaning spray head 60; the switching control valve 40 is provided with a first water outlet 41a, a second water outlet 41b and at least one water inlet 41c, the first water outlet 41a is communicated with the water inlet device 20, and the second water outlet 41b is communicated with the cleaning nozzle 60; the cover body 50 is detachably laid on the top surface of the body 10 to form a closed cavity; the cleaning nozzle 60 is installed on the inner wall of the body 10, and the second water outlet 41b is connected by operating the switching control valve 40, so that the cleaning nozzle 60 discharges water to clean the closed cavity.

In the present invention, the number of the cleaning nozzles 60 may be one, two or more, and the installation position may be a bottom wall or a side wall, and preferably, one, is installed at the bottom of the body 10 near the middle position. The switching control valve 40 has one or two, preferably two, water inlets 41c, one serving as a hot water inlet and one serving as a cold water inlet. The switching of the water storage and the washing function can be realized by manipulating the switching control valve 40.
