The invention provides a control method, and a control system of a clothes nursing machine and the clothes nursing machine. The control method of the clothes nursing machine comprises following steps: controlling a human sensing module to sense whether a user uses a steam handle or not; and controlling the working state of a steam generator according to a touch signal sensed by the human sensing module. By adoption of the technical scheme, the process of achieving intelligent control over the steam generator according to the application condition of a user is achieved. Meanwhile, power consumption and moisture loss of the clothes nursing machine are reduced and user's experience is enhanced.
