According to the embodiment of invention, a kind of air-conditioning drainage system is provided.
Below in conjunction with the composition and working principle diagram of air-conditioning drainage system of the invention shown in FIG. 1, illustrate the present invention
Implementation.
In one embodiment, air-conditioning drainage system can be located in air-conditioning equipment.It is included at least: drip tray 110,
Liquid level detection device 120 positioned at 110 bottom of drip tray, setting (arrangement) 110 bottom of drip tray pressure sensor 130,
The control mainboard 140 connecting with liquid level detection device 120 and/or pressure sensor 130, air conditioner condensate water draining pump is (in other words
Draw water the water pump of i.e. draining) 150.
Wherein, pressure sensor 130 can detecte the water pressure in drip tray 110, and the pressure value that will test acquisition is made
Control mainboard 140 is sent to for pressure feedback signal；Control mainboard 140 is defeated according to the size of pressure value in pressure feedback signal
The control signal of water pump voltage is increased or reduced out to water pump 150, and pump rotary speed is promoted to accelerate or slow down.Pressure sensor 130
Indicate that condensation water quantity is more (water level is deep) when the pressure detected is larger, the pressure value P 1 obtained is big, then control mainboard 140
According to the pressure feedback signal with the pressure value P 1 that the pressure sensor 130 transmission comes, output increases the control of 150 voltage of water pump
Signal processed promotes 150 faster rotational speed of water pump to water pump 150, increases pumpage；When the pressure that pressure sensor 130 detects
Indicate that condensation water quantity is less (water level is shallow/low) when smaller, the pressure value P 1 obtained is small, then control mainboard 140 is according to the pressure
The pressure feedback signal with the pressure value P 1 that the transmission of sensor 130 comes, the control signal that output reduces 150 voltage of water pump arrive
Water pump 150 weakens the pumpage of water pump 150 to promote 150 spin down of water pump；When the pressure that pressure sensor 130 detects
When power is 0, indicate that no water needs to be discharged, the pressure value P 1 obtained is 0, then control mainboard 140 is according to the pressure sensor

In one embodiment, the liquid level detection device 120, can be used for example varistor, and setting is connecing
The water level depth in drip tray 110 is detected in water pond bottom at any time, because of different liquid level (liquid level size/depth differences, water
Of different sizes, water level height difference), varistor will just generate different pressure.Common rule is that condensation water quantity is bigger
(liquid level is deep) then pressure is bigger, and then pressure is smaller for condensation water quantity smaller (liquid level is shallow).And water pump 150 condenses in pump process
Water size (the liquid level depth, water level height) decides the size that water pump 150 loads, when condensation water quantity big (water level is higher),
Load is just big, and the load the big, and the speed attenuation of water pump 150 is more obvious, and performance of drawing water dies down, and the fluctuation of speed generates the noise that draws water,
When condensation water quantity small (water level is lower), water pump 150 will be likely formed idle running, and energy is converted for vibrating noise, makes to have leisure

Example: pressure sensor 130 may include varistor, etc..
Further, pressure sensor 130 and/or liquid level detection device 120 connect and/or couple with control mainboard 140.
As a result, except through liquid level detection device 120 detects liquid level and makes control mainboard 140 provide water pump 150 and carries out
The driving signal drawn water can also be received the signal of the water pressure from the pressure sensor 130, to water by control mainboard 140
Change is made in the rotation of pump 150 controls such as draw water.
Specifically for example: the pressure sensor 130 detects the water pressure in drip tray 110, when pressure sensor 130 detects
Pressure it is larger when, while indicating that the larger liquid level in other words of condensation water quantity is deep, which be transmitted to control mainboard
140, the electricity for increasing the control signal of 150 voltage of water pump to water pump 150 is exported according to the pressure feedback signal by control mainboard 140
Machine promotes 150 faster rotational speed of motor driven water pump, increases pumpage；And when the pressure that pressure sensor 130 detects is smaller
When, while indicating that the smaller liquid level in other words of condensation water quantity is shallow, which is transmitted to control mainboard 140, by controlling
Mainboard 140 transmits the control signal for reducing 150 voltage of water pump to the motor of water pump 150 according to the pressure feedback signal, promotes electricity
Machine drives 150 spin down of water pump (or even arrive and stop), weakens the pumpage of water pump 150.

The lower position of liquid level detection device 120 itself, alternatively, combined with liquid level detection device 120, etc..
In one embodiment, can use positioned at 110 bottom of drip tray the pressure sensor 130 detection this connect
Water pressure in water pond 110 generates a pressure feedback signal by the sensor.Pressure feedback signal includes the pressure sensing
The pressure value that device detects, the pressure value have opposite sizes values, such as pressure value P 1=10N (newton), 15N etc..
Step S120, according to the size of the pressure value in the pressure feedback signal, control is output to the voltage of water pump
Size.
In one embodiment, which sends control mainboard 140 to by pressure sensor 130, control

For example for: the pressure value P 1 that pressure sensor 130 provides is bigger (to be increased, such as: than last in other words
It is big or be more than some threshold value etc.), then control mainboard 140 is exported according to the P1 increases the control signal of 150 voltage of water pump and arrives
The motor of water pump 150 promotes 150 faster rotational speed of motor driven water pump, increases pumpage；The pressure that pressure sensor 130 provides
Force value P1 smaller (reduce in other words, such as: than last small or be lower than some threshold value), then subtract according to P1 output
The control signal of small 150 voltage of water pump promotes 150 spin down of motor driven water pump (or even to stopping to the motor of water pump 150
Only), weaken the pumpage of water pump；As the pressure value P 1=0 that pressure sensor 130 provides, it might even be possible to which water is closed in output
The control signal of pump 150 stops water pump 150 and runs.
An implementation of water pump operation (voltage) is controlled in method of the invention shown in Figure 3 according to the pressure value of detection
