Abstract: Our invention relates to surface-cleaning apparatus having a housing which is adapted to hold a body of liquid that generates foam when air bubbles therethrough. A surface-contacting member, which is carried by the housing and is movable over a surface, functions to distribute foam. Air under pressure is delivered from a source of supply to the inlet of an air line which is located exteriorly of the housing. The outlet of the air line is located within the housing at its bottom and connected to a device to form air bubbles which rise through the body of liquid to generate foam. Foam is conducted through a passageway from the upper part of the housing to the surface-contacting member. A conventional household suction cleaner can be conveniently used as the source of supply of air under pressure. In order to generate foam in the apparatus which is relatively dry and not excessively moist, the air inlet end of the air line is connected to the blowing end of suction cleaner by a coupling which may be referred to as a bypass valve and functions to divert and bleed to the atmosphere a major portion of the air discharged from the blowing end of the suction cleaner. In this way the rate at which air under pressure is delivered to the bottom of the housing through the air line will be correct to generate foam that is relatively dry.
Abstract translation: 本发明涉及具有壳体的表面清洁装置，该壳体适于在气泡通过时保持产生泡沫的液体。 由壳体承载并可在表面上移动的表面接触构件用于分配泡沫。 在压力下的空气从供应源运送到位于外壳外部的空气管路的入口。 空气管线的出口位于壳体的底部并连接到装置上，以形成气泡，其通过液体体积升高以产生泡沫。 泡沫通过从壳体的上部到表面接触构件的通道传导。 传统的家用吸尘器可以方便地用作压力下的空气供应源。 为了在相对干燥且不过度潮湿的装置中产生泡沫，空气管线的进气端通过可被称为旁通阀的联接器连接到吸尘器的吹风端，并且功能是转向 并从吸尘器的吹出端排出的大部分空气排出到大气中。 以这种方式，压力下的空气通过空气管线输送到壳体的底部的速率将是正确的，以产生相对干燥的泡沫。
