Conduit for a condensation removal pump

摘要

A conduit (51) for a condensate removal pump is disclosed comprising a tubular member (47) having a profiled rim (53, 54) at a distal end, profiled such that only a portion of the rim lies in a plane located at the extreme distal end of the tubular member perpendicular to the axis of the tubular. A resilient membrane (52) which has a slit extends across the interior of the tubular member and is arranged to open, to allow water to pass, when water is drawn through the conduit. A combined sensor and suction tube assembly (50) is also disclosed comprising a tube (55), a self heating thermistor (56) coupled to the tube, and a relay means (69) to relay an operational parameter of the self heating thermistor, indicative of the presence of water, to a condensate removal pump. The combined sensor and suction tube assembly is sized to fit within a pipe having an inner diameter of 20 mm.

1. A conduit for a condensate removal pump comprising:
a tubular member having a rim at a distal end thereof, wherein the rim is profiled such that only a portion of the rim lies in a plane which is located at the extreme distal end of the tubular member and which is perpendicular to the axis of the tubular member, and a resilient membrane which extends across the interior of the tubular member, the membrane having at least one slit which is arranged to open to allow water to pass through the membrane when water is drawn through the conduit by a condensate removal pump, wherein the membrane is supported by a support member and wherein the membrane is moveable with respect to the tubular member, the conduit further comprising a resilient member for controlling movement of the membrane, and the tubular member further comprises a housing defining an open chamber within which a first and second thermistor are located.
