Specifically, the second heating unit 4 is operated at a first power when the water level is 3-10mm, and the second heating unit 4 is operated at a second power when the water level is 10-200mm, wherein the second power is greater than the first power; more specifically, the first power is 800-1200W and the second power is 1600-1400W.
The working state of the first heating unit 3 is controlled by collecting the ambient temperature, the working state of the drainage unit 5 is controlled by collecting the ambient humidity, and the working state of the second heating unit 4 is controlled by collecting the water level in the water storage unit, so that the energy-saving advantage is achieved while the potential safety hazard of operation is eliminated.
In summary, it is easily understood by those skilled in the art that the advantageous technical features described above can be freely combined and superimposed without conflict.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
