Description
Technical field
The utility model belongs to draining pump field, especially relevant with a kind of air-conditioning drainage pump with liquid level warning function.
Background technique
Indoor apparatus of air conditioner is when freezing or dehumidify, moisture content in air can condense and be dropped in the water accumulating disc below heat exchanger, the draining pump suction of condensed water in water accumulating disc is got rid of, when draining pump breaks down or discharge pipe line blocks, condensed water in water accumulating disc will exceed the highest water level of setting, cause water to overflow or damage air supply rate, affecting the normal operation of whole air-conditioning system.
Model utility content
The purpose of this utility model be intended to solve existing air-conditioning drainage pump as break down or discharge pipe line blocking time condensed water easily accumulate the problem causing air-conditioning to damage, provide a kind of and can accumulate at water the air-conditioning drainage pump exceeding highest water level alarm.
For this reason, the utility model is by the following technical solutions: the air-conditioning drainage pump with liquid level warning function, comprise pump cover, pump seat, pump shaft, impeller and motor, pump cover and pump seat are composed of a fixed connection and have the pump case of hollow pump chamber, pump case is provided with water intake and water outlet, impeller is placed in hollow pump chamber, pump seat is provided with the left side be spaced a distance, right support post, described motor is installed on a left side, right support post rear end, impeller is anchored on pump shaft, pump shaft is connected with the main shaft of motor through pump seat, driven by motor and rotate, it is characterized in that, described air-conditioning drainage pump also comprises liquid level alarming switch device, described liquid level alarming switch device comprises positive pole inductive rod, negative pole inductive rod and two wire contacts, positive pole inductive rod and negative pole inductive rod are fixed on a described left side respectively as insert-molding injection moulding, in right support post, the front end induction head of two inductive rod all overhangs out corresponding supporting post front end, and be upwards spaced a distance at impeller shaft with described water intake oral area, wherein one end of two wire contacts as insert-molding respectively injection moulding be fixed on a described left side, right support post, left, the each correspondence of right support post connects a wire contact.
During use, wire contact is all wired to air-conditioning control panel, draining pump water intake is inserted in water accumulating disc, when operation of air conditioner, draining pump is in normally open, water in water accumulating disc can be discharged in time, the induction head of positive pole inductive rod and negative pole inductive rod is all on liquid level, if when draining pump breaks down or discharge pipe line blocks, water in water accumulating disc will constantly be expired, when liquid level covers the induction head of the two poles of the earth inductive rod, positive pole inductive rod and negative pole inductive rod are by condensed water conducting, air-conditioning control panel will control warning device and sends alarm signal and control air-conditioning shutdown.
The utility model can reach following beneficial effect: fix as the positive pole inductive rod of insert-molding, negative pole inductive rod and two wire contacts by injection moulding in two supporting posts of pump seat, air-conditioning drainage pump is possessed liquid level warning function, improves the Safety performance of draining pump.
