Water level detecting signal in water bag determine the water level in the water bag be less than preset water level lower limit when, then control water bag into
Water；When the water inlet duration of the water bag reaches preset duration, then the controller controls the water bag and stops intaking, to avoid
The water bag is burst.
In further embodiments, the controller controls the water inlet of the water bag according to water level and stops water inlet.Tool
Body, in this embodiment, the controller is determining the water in the water bag according to the water level detecting signal in the water bag
When position is less than preset water level lower limit, then water bag water inlet is controlled；The controller is also examined according to the water level in the water bag
When survey signal determines that the water level in the water bag is higher than preset second water level upper limit value, then controls water bag and stop water inlet.Wherein,
The preset second water level upper limit value is less than the preset first water level upper limit value.
In other embodiments, the controller controls the water inlet of the water bag, and the control according to water outlet duration
Device controls the water bag according to water level and stops water inlet.Specifically, in this embodiment, water state is used when the water purifier is in
When, the water in the water bag continuously outflows, and the controller obtains the water outlet duration of the water bag；When the water outlet of the water bag
When length reaches default water outlet duration, show that the water water-in-bag is less, the controller controls the water bag water inlet at this time.Institute
During stating water bag water inlet, the water level detecting part is detected water level in the water bag, when the controller is according to
When water level detecting signal in water bag determines that the water level in the water bag is higher than preset second water level upper limit value, then water bag is controlled
Stop water inlet.
In the present invention, when the water inlet duration is less than preset duration, the controller is according only to the water in the water bag
Signal is detected to determine whether the water bag stops water inlet in position.Only when the water inlet duration reaches preset duration, institute
State controller just controlled according to the time water bag stopping water inlet, can so avoid when the water level detecting part or its
When its component breaks down, the water bag is intake always the generation of phenomenon.The method for controlling water level of the present invention does not rely solely on one
