The first temperature controller 13 is configured to detect the temperature of the first heat conducting plate 121 in real time, and control the energization of the first heating pipe 122 according to the detected temperature; for example, when the temperature of the first heat conducting plate 121 is detected to be higher than the set temperature, the first temperature controller 13 will control the first heating pipe 122 to be powered off, and stop heating; when the temperature of the first heat conducting plate 121 is detected to be lower than the set temperature, the first temperature controller 13 controls the first heating pipe 122 to be electrified to continue heating; the occurrence of unsafe problems such as fire caused by overhigh temperature of the first heat conducting plate 121 is effectively avoided.
In this embodiment, because the first heating assembly 12 and the second heating assembly 22 are symmetrically disposed with respect to each other, they have a cooperative effect such that the temperature in the steam heating chamber and the steam generating chamber, which are in communication with each other, is rapidly increased.
In the present embodiment, the U-shaped second heating pipe 222 and the U-shaped first heating pipe 122 are arranged opposite to each other, and since the U-shaped heating pipe is divided into a high temperature region and a low temperature region due to structural limitations, in order to ensure uniformity of temperature in the steam heating chamber and the steam generating chamber, when the U-shaped second heating pipe 222 and the U-shaped first heating pipe 122 are both U-shaped heating pipes, they need to be arranged opposite to each other, as shown in fig. 1 to 4.
