Roller washing machine control method and device and roller washing machine

The embodiment of the invention discloses a control method and device of a roller washing machine and the roller washing machine, and the control method of the roller washing machine comprises the steps that current temperature information is obtained, and the current temperature information comprises environment temperature information and/or weather temperature information of the roller washing machine; judging whether the current temperature information is lower than an icing judgment temperature or not; if yes, whether a drainage pump of the roller washing machine is in an icing state or not currently is judged; if yes, a deicing method is determined according to the icing state, and the roller washing machine is deiced. According to the control method provided by the embodiment of the invention, the current temperature information is firstly acquired, the acquired current temperature information is compared with the icing judgment temperature, and then the icing state of the drainage pump is determined,
