Abstract
The application provides a steam generator and a cooking appliance. The steam generator comprises a shell, the shell having a heat-conducting part; a flow guide pipe arranged in the shell, at least a part of the flow guide pipe being located in the shell, the part of the flow guide pipe located in the shell extending in a spiral shape; and a heating element arranged in the shell, at least a part of the heating element being located in the shell, the part of the heating element located in the shell being located on the side of the flow guide pipe, the heat-conducting part covering the part of any one of the flow guide pipe and the heating element located in the shell, and the heat-conducting part filling the gap between the flow guide pipe and the heating element; wherein the heating element is used for supplying heat to the flow guide pipe. In the application, the medium can flow along the pipe wall of the flow guide pipe extending in a spiral shape, and the medium moves close to the side of the flow guide pipe close to the heating element under the action of the inertial centrifugal force in the process of flowing, so that the medium is closer to the heating element. The arrangement can enhance the disturbance effect of the fluid, can enhance the heat exchange effect, and can effectively improve the heat exchange coefficient.
