摘要： A vacuum cleaner head for cleaning hard floor surfaces comprises an elongate transverse suction mouth (22) on its underside disposed between front and rear rollers (20,21) having a plurality of axial sealing blades arranged to engage the floor surface and to rotate about an axis which extends parallel to the floor surface. The front and rear longitudinal side edges of the suction mouth (22) comprise respective depending static seals (23,24). A suction inlet ((31) is disposed between each roller (20,21) and its respective adjacent seal (23,24). In use, when the head is moved forwardly, surface dirt passes under the front roller (20) and is drawn upwardly to the suction inlet (31). When the head (10) passes over a crevice in the floor, air is drawn through the crevice by the suction mouth (22).

摘要： A vacuum cleaner comprises a cyclonic separator having a tubular wall (11) formed with a constriction intermediate its opposite ends between upper and lower regions (12, 13) of the separation chamber. The constriction helps to improve the separation efficiency of the cleaner and to avoid the re-entrainment of deposited dust.

摘要： An electrical heating element for use, for example, in a domestic iron and comprising essentially a metallic base plate having a coating of a glass ceramic dielectric upon which is laid an electrically resistive track produced from a platinum-containing material whose electrical conductivity falls as its temperature rises thus providing a self-limiting characteristic for the element. The resistive track is covered with further dielectric material and the element is incorporated along with appropriate control circuitry and equipment, into an appliance to be heated. The resistive track has a temperature coefficient of resistance which is sufficiently positive that at a pre-determined maximum temperature its electrical resistivity is at a level at which the rate of electrical energy absorption is substantially equal to the rate of heat loss.

摘要： A vacuum cleaner comprises a cyclone separator having a cyclone chamber (15) for separating matter contained in the airflow, An inlet duct (14) for the flow of fluid (5) extends tangentially into the upper end of the cyclone through the sidewall 10 thereof. The upper end of the cyclone chamber (15) is closed by an upper end wall (11) and a tubular outlet duct or so-called vortex finder (12) extends into the cyclone chamber (15) from the upper end wall (11). A cross member (13) extends across the upstream end of the vortex finder (12) between circumferentially-spaced wall portions 10 thereof. The cross member (13) mechanically stiffens the vortex finder (12) and helps to reduce noise-generating vibrations. The cross member also serves to disrupt the airflow at the inlet to the vortex finder, (12) thereby preventing any airflows which may induce resonance.

摘要： A changeover valve, for an upright vacuum cleaner, comprises a movable valve member (31) connected via a flexible duct to a dirt separator of the cleaner, and a valve body (30) having inlet ports (32, 33) connected, respectively, to an air inlet in the underside of a floor-engaging unit of the cleaner and, via a flexible hose, a suction nozzle of the cleaner. The valve member (31) is movable relative to the valve body (30) for selective alignment with either of the inlet ports (32, 33).

摘要： A vacuum cleaner comprises a rigid removable dust receptacle (15) which is rotatable between first and second positions. In the first position, an aperture (22) in the wall of the receptacle (15) registers with a suction source (20) on the body of the cleaner so air is evacuated from between the receptacle and a liner (25), such as a plastic bag, which is fitted inside the receptacle (15) thereby drawing the liner (25) tightly against the wall of the receptacle (15). When no liner (25) is fitted, the receptacle (15) is positioned in the second position so that the suction source (20) is disconnected from the receptacle (15) and the aperture (22) is sealed.
