The present invention relates to a dehumidifier, and more particularly, to a condensate detecting device and a method of detecting the dehumidifier capable of accurately detecting the condensate contained in the bucket and efficiently controlling the dehumidifier configured therein.

In general, the dehumidifier sucks in indoor humid air into the cabinet, passes through a heat exchanger consisting of a condenser and an evaporator through which refrigerant flows to lower the humidity, and then discharges the dehumidified air back into the room, thereby lowering the indoor humidity. Device.

That is, the dehumidifier uses a method of taking heat from the surrounding air by evaporating the liquefied refrigerant in the evaporator. As the refrigerant evaporates, the temperature of the evaporator is lowered, and the temperature of the air passing through the evaporator is also lowered.

Therefore, as the temperature around the evaporator decreases, the moisture contained in the air condenses to form condensed water on the surface of the evaporator.

Hereinafter, a dehumidifier according to the prior art will be described with reference to the accompanying drawings.
