The invention mainly provides a steam generating device between the water tank and the electric heating plate, and uses the steam generating device to provide sufficient heat energy to feed the water, so that the water can be converted into overheating and greater than normal pressure before being transferred to the hot plate. steam. In the present invention, the steam generating device is a pipe having a heating function, or a boiler having a flow path structure, that is, the steam generating device of the present invention utilizes a space for increasing the conduction area and a space for restricting steam expansion. To achieve the purpose of generating superheated and more than normal pressure steam.

Embodiment 1 Please refer to FIG. 2A and FIG. 2B. FIG. 2A and FIG. 2B are respectively a side cross-sectional view and a top cross-sectional view of a steam generating device 200 according to a preferred embodiment of the present invention. The steam generating device 200 includes a body 210 and at least one retaining wall 222, wherein the body 210 has a steam generating chamber 220 and an upper casing 210a and a lower casing 210b surrounding the steam generating chamber 220. Having on the upper housing 210a An air outlet 214 has a water inlet 212 on the lower casing 210b, and an electric heating pipe 230 is disposed on the lower casing 210b. The retaining wall 222 is disposed in the steam generating chamber 220 for partitioning the steam generating chamber 220 into a first-class passage 220a. One end of the flow passage 220a is configured to communicate with the water inlet 212 of the steam generating chamber 220, and the flow passage 220a is further One end is for communicating with the air outlet 214 of the steam generating chamber 220, and the size of the aperture of the flow channel 220a is smaller than the cross-sectional size of the steam generating chamber 220. In this embodiment, the retaining wall 222 is a spiral retaining wall, thereby forming a spiral flow passage 220a in the steam generating chamber 220, as shown in FIG. 2B, but not limited thereto, the retaining wall 222 can also be The other retaining wall of the curved shape is used to form a curved flow path in the steam generating chamber 220, that is, the present invention does not limit the shape of the retaining wall 222 as long as it can separate a curved meander in the steam generating chamber 220. The flow path 220a is sufficient. Since the flow path 220a partitioned by the retaining wall 222 in the steam generating chamber 220 can increase the conduction area, the efficiency of vaporization into steam can be effectively improved.
