6. The method for controlling an air conditioner according to claim 5, further comprising the step of, after the air conditioner enters the humidification mode:
after the air conditioner enters a humidifying mode, determining whether the difference value between the current return air humidity and the target humidity is smaller than a preset deviation value △;
and if so, controlling a humidifier in the air conditioner to be in an open state.
7. The control method of an air conditioner according to any one of claims 3 to 6, wherein the predetermined deviation value is any one of values of 0 to 30%.
8. An air conditioner, characterized by comprising a refrigeration module and a humidification module, wherein the refrigeration module and the humidification module are respectively and electrically connected with a controller, the refrigeration module is communicated with the humidification module through a pipeline, and the controller is used for executing the steps of the control method of the air conditioner as claimed in any one of claims 1 to 7.
9. The air conditioner as claimed in claim 8, wherein a purification module is further disposed between the refrigeration module and the humidification module, the purification module is used for filtering and purifying condensed water output by the refrigeration module, and the purification module is respectively communicated with the refrigeration module and the humidification module through pipes.
10. The air conditioner as claimed in claim 9, wherein the purification module comprises a water collection tank, a filter element and a water outlet tank which are sequentially communicated, the water collection tank is communicated with the purification module through a pipeline, and the water outlet tank is communicated with the humidification module through a pipeline.
