Through three different states of the first valve 321 and the second valve 322, four warm air outlet modes of the bathroom heater 100 can be realized. It should be noted that, in this embodiment, the first air duct 315, the second air duct 316, and the third air duct 317 can be blocked by the baffle 3211 of the first valve 321 or the second valve 322, and at this time, the first limiting member 312, the second limiting member 313, and the third limiting member 314 are not disposed in the valve accommodating cavity 311, so as to ensure that the first valve 321 and the second valve 322 can rotate smoothly. In order to precisely control the movement state of the first valve 321 and the second valve 322, a positioning sensor may be provided to position the rotational positions of the first valve 321 and the second valve 322.

In summary, the bathroom heater 100 of the present invention has a simple structure and a low cost, and the valve switching assembly 32 includes the first valve 321 and the second valve 322 which are disposed in a staggered manner and opposite to each other, and the rotation axes of the first valve 321 and the second valve 322 coincide with each other, the first valve 321 controls the communication between the first fan 2 and the first air outlet portion 4, and the second valve 322 controls the communication between the first fan 2 and the second air outlet portion 5, so that a plurality of heating modes of the bathroom heater 100 can be realized by using one first fan 2 and one valve switching assembly 32, and the application range of the bathroom heater 100 is increased.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
