[0044] like Figure 5 As shown, high-temperature silica gel 35 for heat insulation is provided around the inner edge of the panel 26 along the insulating glass; the high-temperature silica gel 35 is used to isolate the temperature of the glass circle, effectively ensuring that the panel 26 is not deformed by high temperature.

[0045] A support plate 36 is provided on the bottom surface of the panel 26, and a plurality of light strips 37 are provided on the surface of the support plate 36; the support plate 36 serves as a carrier of the light strips 37, so that the light strips 37 can be more reasonably distributed in the bathroom space; the design of the support plate 36 and the light strips 37 makes it easier for users to perform maintenance and replacement work.

[0046] Working principle: When the bathroom heater is turned on for ventilation, a ventilation duct is formed between the blower 24, the fan 23, the air guide grille 22 and the air duct plate 20. The fan-shaped blades 6 and the trapezoidal blades 8 open automatically after ventilation is turned on. When the fan-shaped blades 6 and the trapezoidal blades 8 are turned on, the first docking plate 14 and the second docking plate 14 cooperate with each other, and the third docking plate 15 set on the two trapezoidal blades 8 cooperate with each other to limit the fan-shaped blades 6, the trapezoidal blades 8 and the air duct. In the opening stage, the fan-shaped blades 6 and the trapezoidal blades 8 will not interfere with each other due to the action of the wind. At the same time, the heating tube 25 can be turned on to make the heating glass 27 heat up, and the light strip 37 can be turned on for lighting to provide a comfortable bathing environment. When the ventilation is turned off, the torsion spring 11 pulls the fan-shaped blades 6 and the trapezoidal blades 8 to reset, thereby realizing the self-opening and closing of the fan-shaped blades 6 and the trapezoidal blades 8.

[0047] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
