Dehumidifier and control method thereof

Abstract

According to the dehumidifier and the control method thereof, after a microswitch is closed, a compressor and an air supply device are not controlled to stop immediately, the rotating speed of the compressor is kept unchanged, the rotating speed of the air supply device is reduced, supplied air is reduced, the continuous operation time of the compressor is further detected at the moment, and the closing time of the microswitch is detected again; when the continuous operation time of the compressor is larger than the operation time threshold value, it is indicated that the operation time of the dehumidifier reaches the limit value, it can be determined that the detected water fullness signal is accurate, and at the moment, the compressor and the air blower are controlled to stop; when the closing time of the microswitch is larger than a set value, it is indicated that the closing time of the microswitch is long enough, the compressor and the air blower are controlled to stop, and if the microswitch is closed due to water level fluctuation, the re-detected closing time is very short or zero, and therefore it can be determined that the water fullness signal is accurate. By adopting the embodiment of the invention, the problem of false alarm caused by water level fluctuation of the water tank can be avoided.

Description

technical field [0001] The invention relates to the technical field of dehumidifiers, in particular to a dehumidifier and a control method thereof. Background technique [0002] With the improvement of people's living standard and quality, dehumidification, drying, ventilation and keeping warm of the living environment have gradually become people's daily needs. The air in the specific space is discharged to the above-mentioned specific space, so that the air in the specific space is kept dry. The condensed water generated by the operation of the dehumidifier is generally stored in its water storage device (such as a water tank), and then drained by the user when the water is full. The water full detection method of the dehumidifier in the prior art is as follows: after the main controller detects the water full signal fed back by the water level switch, it immediately alarms to remind the user that drainage is required, and at the same time, the whole machine stops working...

AI Technical Summary

Problems solved by technology

However, when the water level in the water tank is high but does not reach the warning line, the movement of the water tank will cause the water level to fluctuate, and the water level fluctuation may cause the water level switch to falsely detect the full water signal. At this time, the control dehumidifier will stop working even if the water tank is not full. Alarm prompt
