Description

Mute split type air conditioner drainage pump

Technical Field

The utility model relates to an air conditioner drain pump especially relates to one kind and can lay the water tank position according to the arbitrary direction of installation condition, saves installation space, need not routine maintenance, and the little silence split type air conditioner drain pump of noise of operation.

Background

When the air conditioner is used in summer, because its evaporimeter surface temperature is in a lower state, when the higher air of indoor temperature meets low temperature evaporimeter surface, the water in the air will condense and attach to the evaporimeter surface, assemble again in the water collector of below, humidity in the air is big more, the condensate water yield that produces just also increases, because the water collector capacity is limited, consequently, the condensate water in the water collector needs in time to discharge, if receive reasons such as house structure restriction (like basement) influence to lead to when the unable in time discharge of condensate water, must lead to the house bubble top, the fitment is impaired, influence people's daily life and live in. The air conditioner drainage pump is used for lifting the condensed water to a certain height or distance through the micro water pump and then draining the condensed water. The water level sensor of the existing air-conditioning drainage pump generally adopts a float type or an electrode type, wherein the float type water level sensor is that a magnetic ring is arranged on the upper surface of a float, the magnetic ring floats up and down along with the float, and triggers a Hall device or a reed switch at different water level height positions to realize the induction of the water level, and the float often generates certain noise at a triggering position in the process. The electrode type water level sensor has the working principle that when the water level reaches a set height, the two electrodes are submerged, so that the two electrodes are conductive to conduct a pulse signal to realize water level induction, although this approach avoids some of the disadvantages of the float type, the energized electrodes not only polarize and adsorb impurities in the water, and often because of the need to contact with water, the influence of scale still can't be avoided, further influence its use precision and performance, also need regularly to wash and maintain, meanwhile, according to the working principle of a float type water level sensor or an electrode type water level sensor, the water tank of the air-conditioning drainage pump is required to be horizontally arranged, if the drainage pump is placed obliquely, position errors can be generated, so that the use flexibility of the air-conditioning drainage pump is limited, and the use requirements of special spaces, especially narrow and small spaces which are difficult to arrange can not be met.

Disclosure of Invention

The utility model mainly provides a simple structure can lay the water tank position according to the arbitrary direction of installation condition, saves installation space, and the running noise is little, and need not daily maintenance, and silence split type air conditioner drain pump that use cost is low has solved the water tank installation that exists among the prior art and has the directionality, can't satisfy the operation requirement in narrow and small space, and need regularly wash the maintenance to the sensor, the technical problem who wastes time and energy etc..

The above technical problem of the present invention can be solved by the following technical solutions: the utility model provides a silence split type air conditioner drain pump, is including the water tank that is used for collecting the comdenstion water and the miniature pump that communicates on the water tank can be discharged the comdenstion water to the water tank outside inlay on the internal face of water tank and adorn a plurality of capacitanc water level monitoring chip, capacitanc water level monitoring chip cover is in insulating cover and through signal transmission line connection on the controller, the controller is according to the interior liquid level information automatic control miniature pump's of water tank that capacitanc water level monitoring chip detected switch.
