Abstract:
A vacuum cleaner including a pivot assembly having an interior, an exterior, and a pivot assembly electrical connector on the exterior of the pivot assembly. The pivot assembly electrical connector is electrically connected to an electrical component of a surface cleaning head. The vacuum further includes a cleaning wand having a cleaning wand electrical connector. The cleaning wand is received within the interior of the pivot assembly to removably couple the cleaning wand to the pivot assembly to place the cleaning wand in fluid communication with a dirty air inlet of a cleaning head and to removably electrically connect the cleaning wand electrical connector to the pivot assembly electrical connector. The cleaning wand electrical connector is electrically connected to the pivot assembly electrical connector to provide power to the electrical component of the cleaning head from a power source.
Abstract:
A cyclone dust collector having improved usability and a vacuum cleaner having the same are provided. The cyclone dust collector includes: a cyclone chamber including an inlet through which air is drawn in and an outlet through which dust-filtered air is discharged; a discharge passage disposed inside the cyclone chamber; a spiral part formed around the discharge passage to be inclined in a spiral pattern; and a grill rotatably disposed on the discharge passage, and the outlet is formed inside the discharge passage.
Abstract:
The present invention relates to a cleaning appliance of the cylinder type. The cleaning appliance comprises a separating apparatus for separating dirt from a dirt- bearing fluid flow, and a floor-engaging rolling assembly comprising a main body and a pair of floor-engaging wheels. The most rearward point of the separating apparatus is arranged in line with or rearward of the centre point of the wheels.
Abstract:
The present application relates to a cleaning appliance of the cylinder type. The cleaning appliance comprises a separating apparatus for separating dirt from a dirt- bearing fluid flow, and a floor-engaging rolling assembly. The separating apparatus comprises a first cyclonic separating unit having a low efficiency cyclone and a second cyclonic separating unit having a plurality of second cyclones. The rolling assembly comprising a main body and a pair of floor-engaging wheels, and the main body has a recess in which a portion of the separating apparatus is received along a major portion of its length.
Abstract:
The present invention pertains to a robot cleaner. In the configuration of the robot cleaner, a dust case is mounted by magnetic force such that the magnetic force can be sensed, a rag-mounting structure is provided such that whether or not a rag is mounted is sensed so as to restrain the same, infrared sensing modules are provided at both sides of a driven wheel, and infrared floodlight sections are formed on the driven wheel at a uniform interval. Therefore, the dust case according to the present invention is mounted by magnetic force and the magnetic force is sensed, so that the configuration is simplified and manufacturing costs are reduced. In addition, the rag-mounting structure is provided such that the mounting of the rag holder is sensed so as to restrain the same while mounting the rag holder, such that the robot cleaner is prevented from moving to a cushioned area such as a carpet where the rag holder may get stuck. Therefore, a malfunction due to the rag holder does not occur.
Abstract:
A cleaning appliance of the cylinder type includes separating apparatus (12) for separating dirt from a dirt-bearing fluid flow, a floor engaging rolling assembly comprising means for drawing the fluid flow through the separating apparatus, a chassis connected to the rolling assembly (20) and comprising at least one floor engaging support member, and a duct (28) for conveying the fluid flow to the separating apparatus. At least part of the duct is connected to the chassis for& pivoting movement relative to the chassis (32). Biasing means are provided for engaging the duct to urge the pivoting part of the duct towards a rest position relative to the chassis.
Abstract:
Ein beutelloses Bodenpflegegerät (1) mit einem Fliehkraftabscheider (2), der einen Abscheideraum (5) mit einem Lufteinlass (3), einen Luftauslass (6) und einem Auswurffenster (16) aufweist, wobei in dem Abscheideraum eine Luftführungseinrichtung (8) mit einer Prallfläche (9) zur Luftführung angeordnet ist. Das Auswurffenster (16) ist in einer Wand (15) des Abscheideraums (5) in dessen radial seitlicher Richtung offen und die Prallfläche (9) ist vom Lufteinlasses (3) aus gesehen wenigstens teilweise vor dem Auswurffenster (16) angeordnet oder reicht zumindest an den dem Lufteinlass (3) zugewandten Rand (17) des Auswurffensters (16) heran. Eine solche Anordnung erhöht die Abscheideleistung vor allem kleinster Partikel bei zugleich konstant bleibendem Volumenstrom und ohne zusätzliche Verluste der Druckdifferenz in dem Fliehkraftabscheider.
