Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of air conditioner condensation water-level control apparatus and air-conditioning system.
Background technology
Within air-conditioning systems, in prior art, commonly switch detects the condensed water level of interior machine.Switch can control break-make by the magnetisable material inside ball float, and when ball float along with liquid level reaches the position that can control to cut-off, the magnetisable material inside ball float just makes wire connect, and feeds back to the running of mainboard loop and then control water pump.But, switch is adopted to have following weak point: first, a liquid level can only be detected and can not detect liquid level continuously, and water pump is extracted into bubble and the position that sends abnormal sound when can exist in the process of drawing water, switch can only the just action when water is completely protected, and water pump can not be controlled when water pump is extracted into bubble and do not draw water, because there is very large noise problem; Secondly, when water level is lower, (as condensed water in air dried situation produces seldom) water pump is opened continuously and wastes energy and produce noise.
Summary of the invention
There is provided in the embodiment of the present invention that a kind of structure is simple, cost is low, control accuracy is high, reliability is high, air conditioner condensation water-level control apparatus to the continuous detection of water level and air-conditioning system can be realized.
For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of air conditioner condensation water-level control apparatus, comprises pressure sensing cell, for detecting the hydraulic pressure bottom air-conditioning drip tray; Water pump, for discharging the condensed water in air-conditioning drip tray; Controller, is connected with pressure sensing cell and water pump, for controlling unlatching or the closedown of water pump according to the size of hydraulic pressure.
As preferably, pressure sensing cell is piezo-resistance.
As preferably, controller, when the hydraulic pressure that hydraulic pressure meets or exceeds corresponding to predetermined discharge level being detected, is opened water pump and is carried out draining.
As preferably, controller, when the hydraulic pressure that hydraulic pressure is reduced to corresponding to predetermined lowest water level being detected, switches off the pump.
Present invention also offers a kind of air-conditioning system, comprise above-mentioned air conditioner condensation water-level control apparatus, the pressure sensing cell of air conditioner condensation water-level control apparatus is arranged on the bottom of air-conditioning drip tray.
As preferably, the bottom of air-conditioning drip tray is formed with depressed part, and pressure sensing cell is arranged in depressed part.
Owing to have employed technique scheme, the present invention can realize the continuous detection to water level, has the advantages that structure is simple, cost is low, control accuracy is high, reliability is high.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Please refer to Fig. 1, the invention provides a kind of air conditioner condensation water-level control apparatus, comprise pressure sensing cell 1, for detecting the hydraulic pressure bottom air-conditioning drip tray 4; Water pump 3, for discharging the condensed water in air-conditioning drip tray 4; Controller 2, is connected with pressure sensing cell 1 and water pump 3, for controlling unlatching or the closedown of water pump 3 according to the size of hydraulic pressure.
During work, the condensed water in air-conditioning drip tray 4 provides hydraulic pressure to pressure sensing cell 1, and when the water level of condensed water is different, the hydraulic pressure that pressure sensing cell 1 is subject to is not identical yet.Therefore, by the change of hydraulic pressure, the height of water level can be reflected.So, controller 2 just can detect the water level of condenser according to the size of hydraulic pressure continuously, thus realizes continuous level sensing, and then can the action of continuous control water pump 3, to avoid water pump action when being extracted into air and condensation water quantity is less, to reduce noise, to save electric energy; Further, when the water level of condensed water is higher, controller also can control water pump and open, and to avoid the spilling of condensed water, has the advantages that structure is simple, cost is low, control accuracy is high, reliability is high.
As preferably, pressure sensing cell 1 is piezo-resistance.Piezo-resistance can produce different resistances along with suffered pressure difference, when liquid level changes, liquid will change the pressure of piezo-resistance, and then the resistance of piezo-resistance changes, then electric current in circuit will change, and then the current signal of change can be fed back to controller 2, controller 2 just can pass through the open and close of the logic control water pump 3 established in advance.
As preferably, controller 2, when the hydraulic pressure that hydraulic pressure meets or exceeds corresponding to predetermined discharge level being detected, is opened water pump 3 and is carried out draining.Like this, the problem that condensed water overflows can be prevented.
As preferably, controller 2, when the hydraulic pressure that hydraulic pressure is reduced to corresponding to predetermined lowest water level being detected, switches off the pump 3.Like this, water pump action when being extracted into air and condensation water quantity is less can be prevented, to reduce noise, to save electric energy.
Present invention also offers a kind of air-conditioning system, comprise above-mentioned air conditioner condensation water-level control apparatus, the pressure sensing cell 1 of air conditioner condensation water-level control apparatus is arranged on the bottom of air-conditioning drip tray 4.
As preferably, the bottom of air-conditioning drip tray 4 is formed with depressed part 5, and pressure sensing cell 1 is arranged in depressed part 5.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
