The invention provides a heating cooker. The heating cooker comprises a cylindrical cavity body and an upper cover, a heating cavity for storing food is formed in the cavity body, the upper cover overs the cavity body, and the upper cover and the cavity body define an upper electric appliance chamber. The upper electric appliance chamber is internally provided with a heating pipe, a heating pipe cover and multiple fixing brackets, the heating pipe is used for generating heat to heat the heating cavity, the heating pipe cover is disposed above the heating pipe, the heating pipe is installed inthe heating pipe cover, at least a first mounting surface is formed on each fixing bracket, and the first mounting surfaces are used for connecting the heating pipe cover to the fixing brackets. According to the technical scheme, the structure is simple, and installation and dismantling of the cavity body and heating pipe cover are convenient. In the specific installation process, the fixing brackets can be fixed to not only the cavity body but also the heating pipe cover. By prearranging the fixing brackets on one of the cavity body and the heating pipe cover and then assembling with the other of the cavity body and the heating pipe cover, the installation efficiency is improved, and the installation procedure is simplified.
