Through controlling the positive and negative rotation of the stepping motor 23, the positive and negative rotation of the first motor 11 and the positive and negative rotation of the second motor 13 respectively, the functions of double air blowing, double air exhausting, one air blowing and one row exhaust and the like can be realized, air exhausting is carried out while introducing fresh air, the air pressure in the bathroom is not positive pressure, and turbid air is prevented from being introduced into places such as bedrooms, living rooms and the like.

In summary, the bathroom heater provided by the embodiment of the present disclosure has the following advantages:

1) because two motors which can rotate forward and backward are adopted, the two motors rotate forward and backward at the same time, so that large air volume blowing of the bathroom heater is realized, air circulation in a bathroom can be accelerated, and heating time of a bathroom space is shortened during heating; the two motors rotate reversely at the same time, so that large-air-volume air exhaust of the bathroom heater is realized, and turbid air in a bathroom can be exhausted in a short time;

2) by arranging the first housing and the second housing above the second wind wheel and utilizing a driving mode of combining the stepping motor with the gear and the rack, when the fresh air function is not started, the first housing is opened, the fresh air duct is closed, and the blowing and exhausting air is indoor air; when the fresh air function is started, the first housing is closed, the fresh air duct is opened, fresh air is introduced through negative pressure generated by high-speed rotation of the second wind wheel, the introduced air is fresh outdoor air, and the introduced amount of the fresh air is increased;

3) when the fresh air function is started, the first motor is started to exhaust air, so that the turbid air in the bathroom is exhausted while fresh air is introduced, the air pressure in the bathroom is kept not higher than the air pressure in a bedroom, a living room and the like, and the turbid air in the bathroom overflows;

4) when opening the new trend function, the new trend of introducing can pass through heating module, can realize when introducing the new trend when chilly winter, and what get into the bathroom after the heating module effect is warm new trend, and in hot summer, heating module does not act when introducing the new trend.
