The invention discloses a bathroom warmer, belonging to the field of household electric heating appliances. Specific to the defects that low optothermal conversion rate, slightly large volume and harmful ultraviolet ray inclusion exist in an infrared heating lamp bulb adopted in a heating body of the traditional bathroom warmer, a light-emitting diode (LED) is adopted in the invention; preferably, a multi-chip integrate LED is adopted as the heating body of the bathroom warmer, can be used for generating optothermal radiation with the preferable wavelength range of 0.4-5mum so as to quickly increase the temperature of a human body and intra-domain temperature, and the bathroom warmer has the advantages of high optothermal conversion efficiency, obvious energy-saving effect, long service life, and light, thin and small equipment; meanwhile, optical radiation wave bands can be selected and used in a combination manner according to the wavelength of the LED, wherein no harmful ultraviolet rays are generated, and the visible light wave band and the infrared wave band have a physiotherapy health-care effect on a human body; and the bathroom warmer disclosed by the invention is in accordance with the concepts on greenness, health and energy saving and is a very practical novel bathroom warmer, and a novel approach to the application of the LED is provided.
