An embedded heating cavity provided with a water cup comprises a hollow cavity and further comprises the water cup with a top opening, wherein the water cup is arranged at the middle upper part of the inside of the cavity, a water outlet extending out of the side wall of the cavity is formed in the water cup, and a cold water inlet is formed in the side wall of the lower part of the cavity. The embedded heating cavity has the benefits as follows: the heating cavity adopts an embedded heating mode, drinking water includes splattering hot water and steam water, impurities settle at the bottom of the cavity, and water drinking is safer and more hygienic; after heating is stopped, hot water in the cavity can keep the drinking water in an inner container warm through waste heat, and people can still drink warm water in a certain period of time after heating is stopped; a flange-type connector of the cavity can improve the sealing performance of the cavity, the water leaking and seepage problems are effectively solved, and the embedded heating cavity is more convenient to disassemble, assemble and maintain.
