Abstract
The invention discloses a liquid level continuous detection device, an air-conditioner condensate water level control device and an air-conditioner system. The liquid level continuous detection device comprises a floater and a slide rheostat, wherein the floater drives a pointer of the slide rheostat to move to adjust the resistance value of the slide rheostat, so that the slide rheostat outputs a liquid level signal corresponding to the position of the floater. According to the liquid level continuous detection device, the resistance value of the slide rheostat can change under the driving of the floater so as to reflect the liquid level, and then continuous detection of the liquid level can be achieved. The liquid level continuous detection device has the advantages of being simple in structure, low in cost, high in control precision and high in reliability.
Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of continuous detecting level gauge, air conditioner condensation water-level control apparatus and air-conditioning system.
Background technology
Within air-conditioning systems, in prior art, commonly float switch detects the condensed water level of interior machine.Float 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, float switch is adopted to have following weak point: first, can only detect a liquid level can not continuous detecting liquid level, and water pump is extracted into bubble and the position that sends abnormal sound when can exist in the process of drawing water, float 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 condensate 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, can realize the continuous detecting level gauge of the continuous detecting to water level, air conditioner condensation water-level control apparatus and air-conditioning system.
For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of continuous detecting level gauge, comprise: float and slide rheostat, float drives the hand motion of slide rheostat to regulate the resistance of slide rheostat, thus makes slide rheostat export the liquid level signal corresponding with the position of float.
As preferably, continuous detecting level gauge also comprises connecting rod, and float is connected with pointer by connecting rod.
As preferably, continuous detecting level gauge also comprises guide pole, and float is arranged on the guide bar actively.
Present invention also offers a kind of air conditioner condensation water-level control apparatus, comprise above-mentioned continuous detecting level gauge, for detecting the water level of air-conditioning drip tray; Water pump, for discharging the condensate water in air-conditioning drip tray; Controller, is connected with continuous detecting level gauge and water pump, for controlling unlatching or the closedown of water pump according to the height of water level.
As preferably, controller, when detecting that water level meets or exceeds predetermined discharge level, is opened water pump and is carried out draining.
As preferably, controller, when detecting that water level is reduced to predetermined lowest water level, 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 present invention can utilize float to drive the resistance of slide rheostat to change, and to make the height of reflection liquid level, thus realizes detecting the connection of liquid level, has the advantages that structure is simple, cost is low, control accuracy is high, reliability is high.

Embodiment
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 continuous detecting level gauge, comprise: float 1 and slide rheostat 2, float 1 drives the pointer 3 of slide rheostat 2 to move to regulate the resistance of slide rheostat 2, thus makes slide rheostat 2 export the liquid level signal corresponding with the position of float 1.
When liquid level changes, float 1 under the effect of buoyancy along with liquid level lifting, and pointer 3 can move with float 1, therefore, the position of pointer 3 will change, so, the resistance of slide rheostat 2 is changed, thus the electric current be applied on slide rheostat 2 is changed, utilize the change of this electric current just can reflect the height of liquid level, thus realize detecting the connection of liquid level, have the advantages that structure is simple, cost is low, control accuracy is high, reliability is high.
Preferably, continuous detecting level gauge also comprises connecting rod 4, and float 1 is connected with pointer 3 by connecting rod 4.Connecting rod 4 can be arranged vertically, and one end is connected with float 1, and the other end is connected with pointer 3, and like this, when float 1 moves up and down, pointer 3 will correspondingly move up and down.
Preferably, continuous detecting level gauge also comprises guide pole 5, and float 1 is arranged on guide pole 5 actively.During installation, guide pole 5 is installed vertically, to make float 1 when moving up and down, can move along guide pole 5 by predefined paths, guarantees that the motion of float 1 can reliably drive pointer 3 to move, the phenomenons such as stuck can not occur.
Please refer to Fig. 1, present invention also offers a kind of air conditioner condensation water-level control apparatus, comprise above-mentioned continuous detecting level gauge, for detecting the water level of air-conditioning drip tray 6; Water pump, for discharging the condensate water in air-conditioning drip tray 6; Controller 7, is connected with continuous detecting level gauge and water pump, for controlling unlatching or the closedown of water pump according to the height of water level.
During work, the condensate water in air-conditioning drip tray 6 provides buoyancy to float 1, and when the water level of condensate water is different, the height of float 1 is not identical yet.Therefore, by the change of float 1 position, the height of water level can be reflected.So, the continuous detecting that controller 7 just can realize condenser water level according to the change of the continuous position of float 1, and then can the action of stepless control water pump, to avoid water pump action when being extracted into air and condensation water quantity is less, to reduce noise, saves energy; Further, when the water level of condensate water is higher, controller also can control water pump and open, and to avoid the spilling of condensate water, has the advantages that structure is simple, cost is low, control accuracy is high, reliability is high.
Preferably, controller 7, when detecting that water level meets or exceeds predetermined discharge level, is opened water pump and is carried out draining.Like this, the problem that condensate water overflows can be prevented.
Preferably, controller 7, when detecting that water level is reduced to predetermined lowest water level, switches off the pump.Like this, water pump action when being extracted into air and condensation water quantity is less can be prevented, to reduce noise, saves energy.
Present invention also offers a kind of air-conditioning system, comprise above-mentioned air conditioner condensation water-level control apparatus.
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.
