Embodiment Construction

[0022] figure 1 and figure 2 The suction nozzle, also referred to as floor suction nozzle, is shown schematically in a bottom view according to a preferred embodiment of the invention. The suction nozzle has a housing 1 made of plastic, on which a bottom plate 2 is formed on the bottom side. Formed below the base plate 2 is a suction chamber 3 into which the suction channel 4 opens and which forms the suction opening 5 as an opening on the bottom side. as from figure 1 It can be seen that the bottom plate 2 and the suction opening 5 have the shape of an isosceles triangle, the base 6a of which represents the front side of the suction nozzle in the advancing direction.

[0023] The suction channel 4 is connected in a fluid-tight manner to a connecting sleeve (not shown) arranged on the upper side of the housing 1 . On this connecting sleeve, the hand control and / or the flexible hose can be connected in a fluid-tight manner to the basic housing of the vacuum cleaner, in whi...

Abstract

The invention relates to a suction nozzle of a vacuum cleaner for absorbing dirt and / or dust from the floor by means of a suction airflow, which has a housing (1), a suction chamber (3) formed inside the housing (1), for guiding the suction airflow And lead to the suction channel (4) in the suction chamber (3) and form the suction opening (5) as the bottom side opening of the suction chamber (3), wherein the suction opening (5) has a central suction opening section (6 ) and two side suction inlet sections (7) located on both sides of the central suction inlet section (6), and the suction inlet (5) is arranged so that part of the suction airflow ≥ 40% and ≤ 65% flows through the central suction Mouth section (6).

Description

technical field [0001] The invention relates to a suction nozzle of a vacuum cleaner for sucking dirt and / or dust from the floor by means of a suction airflow, which has a housing, a suction chamber formed inside the housing, a suction channel for guiding the suction airflow and opening into the suction chamber And a suction port is formed as the bottom side opening of the suction chamber. Background technique [0002] Suction nozzles are known in practice, referred to as accessories, also simply as suction nozzles or, depending on the purpose of use, as hard floor nozzles or carpet nozzles, and these nozzles are usually used together with vacuum cleaners to suck up dirt from the floor and / or dust. Vacuum cleaners with suction nozzles of this type usually have a base housing in which an electric suction motor for forming the suction air flow is arranged. The suction nozzle is usually connected fluid-tightly to the main body housing of the vacuum cleaner via a flexible suct...
