In some embodiments of the present invention, referring to fig. 2, step S5 controls the indicator lamp 5 to be turned on when the fan 2 is controlled to stop operating. Therefore, the indicator lamp 5 can intuitively display the water full state of the water outlet tank 3, so that the user can drain water according to the prompt of the indicator lamp 5.
Further, as shown in fig. 2, the method for controlling the dehumidifier 100 further includes the following steps: and S7, when the fan 2 is controlled to stop running, when the time for detecting that the water tank 3 is in the non-full state reaches a fourth preset time t4, the indicator lamp 5 is controlled to be turned off, and the dehumidifier 100 is restarted. Therefore, when the water tank 3 is detected to be in the non-full state and continuously reaches the fourth preset time t4, the fact that the water in the water tank 3 is drained can be determined, and the dehumidifier 100 can be restarted to keep the indoor humidity within a reasonable range.
In some embodiments of the present invention, referring to fig. 1, a water level switch 31 is disposed in the water tank 3, and the step of determining whether the water tank 3 is in a full water state includes: detecting a water level signal in the water tank 3, wherein the water level signal is obtained by monitoring the state of the water level switch 31 in real time, and when the water level switch 31 is closed, judging that the water tank 3 is in a full water state; when the water level switch 31 is turned off, it is judged that the water tank 3 is in a non-full state. For example, when the water in the water tank 3 contacts the contact of the water level switch 31, the water level switch 31 is closed, and the water level signal is fed back to the water tank 3 to be in a full state, and when the water in the water tank 3 does not contact the contact of the water level switch 31, the water level switch 31 is opened, and the water level signal is fed back to the water tank 3 to be in a non-full state. When the steps S1 to S6 are adopted, frequent turning on or off of the water level switch 31 due to water surface fluctuation can be avoided, the requirement on the stroke of the water level switch 31 is low, that is, the water level switch 31 can be the water level switch 31 with a short stroke, the structural design difficulty of the dehumidifier 100 can be reduced, the generalization level of the water level switch 31 is improved, and the cost is reduced.
