The utility model discloses an in some embodiments's host computer stoving mode, water valve and water pump are closed, and main part motor and driving motor keep the operation, and heating element and base fan start, under the combined action of main part motor and base fan, the air current passes through the heating element heating, through wind channel and sewage case, finally discharges through the main part motor.

In this process, the drum brush is rotated at a fourth rotation speed for a fourth time while the main body motor sucks the hot air into the air duct and the sewage tank at a second gear and discharges the hot air. Wherein the power of the second gear is lower than the power of the first gear. The fourth time is greater than any of the first to third times, preferably the fourth time is at least one order of magnitude longer than any of the first to third times. For example, the first to third times are counted in seconds, and the fourth time is counted in minutes. By this step, the air duct, the filter assembly on the waste tank, such as HEPA screen, is dried.

In the rolling brush drying mode, the main body motor, the water valve and the water pump are in a closed state, and the driving motor, the heating assembly and the base fan are in an operating state; the round brush is at the uniform velocity and is rotated, and under base fan and heating element's effect, moisture on the round brush evaporates fast, reaches the fast drying effect.

In the rolling brush air drying mode, the main body motor, the water valve, the water pump and the heating assembly are in a closed state, and the driving motor and the base fan are in a running state; the rolling brush rotates at a constant speed, and the hair of the rolling brush is gradually dried until the hair is completely dried under the action of the fan of the base.

The utility model discloses an among the automatically cleaning-drying pattern, the running parameter of first, second, third, fourth rotational speed and operating duration, first gear and second gear can be the parameter of predetermineeing in the major control system. Of course, as will be fully understood by those skilled in the art, the adjustment/setting can be performed in real time by the master control system according to the detected condition of the roll brush, as long as the basic logic meets the design logic of the inventor.

The utility model discloses an in some embodiments, the major control system of base and host computer subassembly can set up respectively to satisfy the condition of the different host computers of base adaptation. The user can pair the base with the host parameters on the App.

Theoretically, the host drying mode, the rolling brush drying mode and the rolling brush air drying mode can be interchanged in sequence. In some preferred embodiments of the present invention, the main machine drying mode precedes the rolling brush drying mode. This is because the main unit motor is turned on in the main unit drying mode, and although the power is lower than that in the self-cleaning mode, the sound is still loud and long lasting. If the tumble drying mode is first applied, the user may experience noise after a quiet period of time, which the inventors believe is not a good use experience.

In other preferred embodiments of the present invention, the drum brush drying mode is performed after the drum brush drying mode. The purpose is to utilize the waste heat of the heating assembly as much as possible and save energy.

From the user perspective, one-key automatic cleaning of the rolling brush and the pipeline can be realized. After cleaning, hot air drying is started, and the whole-channel efficient drying is initiated, so that not only the rolling brush, but also the pipeline, the filter screen and the sewage tank can dry and remove peculiar smell, and the generation of mold caused by stain residue is avoided. Additionally, the utility model discloses a stoving or air-dry mode have cooperated the comb-tooth form wind-guiding portion on the base, have further improved stoving and/or air-dried efficiency, and energy-concerving and environment-protective more accords with the development trend of green technology.
