S303, when the liquid level rate of climb is second speed, the valve opening of the first drainpipe is the second aperture, controls institute
The valve opening for stating the second drainpipe is 100%；
S304, when the liquid level rate of climb is third speed, the valve opening of the first drainpipe is 0%, controls described the
The valve opening of two drainpipes is third aperture；
Wherein, the First Speed is greater than second speed, and the second speed is greater than third speed, and first aperture is big
In the second aperture.
In the present embodiment, the liquid level rate of climb in drip tray shows that the water of condensed water is larger in First Speed,
It can collect in drip tray rapidly, at this point, the second drainpipe is fully opened, the valve opening setting of the first drainpipe is the
One aperture assists the draining of the second drainpipe, increases the discharge amount of condensed water, in this way, water is made to maintain the second position of drain pipe
Place, can satisfy the use demand of atomizer.The liquid level rate of climb in drip tray shows that condensation water quantity is suitable in second speed
In, at this point, adjusting the valve opening of the first drainpipe to the second aperture, the second aperture makes second row less than the first aperture
Water pipe fully opens, and reduces the discharge amount of condensed water, is maintained at liquid level near the second drainpipe, uses need to meet atomizer
It asks.When the liquid level rate of climb in drip tray is in third speed, show that condensation water quantity is smaller, at this point, the first drainpipe is closed,
And the valve opening of the second drainpipe is adjusted to the discharge rate for reducing condensed water to third aperture, to guarantee that water meets atomization
The use of device.
In one embodiment of the invention, the first aperture is 31%~50%, and second aperture is 10%~30%,
The third aperture is 30%~50%.
When the first aperture is 31%~50%, the first drainpipe can assist the second drainpipe to be drained.When second
It when aperture is 10%~30%, can suitably reduce the discharge amount of condensed water, stablize the water in drip tray.Third aperture is
When 30%~50%, condensed water can be suitably stored in drip tray.In this way, the water in drip tray is made to meet atomization demand.
In one embodiment of the invention, further includes:
According to the time of first time point, the liquid level at the second time point and first time point to the second time point
Interval calculates the liquid level rate of climb.Specifically, liquid level rate of climb v=(h2-h1)/△ t, wherein h1For the liquid of first time point
Face height；h2For the liquid level at the second time point；△ t is time interval of the first time point to the second time point.It is exemplary
Ground, h1=10mm, h2=15mm, △ t=20s, then the liquid level rate of climb is v=(h2-h1)/△ t=(15-10)/20=
0.25mm/s。
In one embodiment, as shown in Figure 5, further includes:
S401, the liquid level and the liquid level at the second time point for determining first time point respectively；
