Definitions

• the invention relates to a Staubsauger foundeddüse according to the preamble of claim 1.
• canister vacuum cleaners In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers.
• An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose to the housing or the blower of the vacuum cleaner and has at its other end to a floor nozzle, which comes into contact with the surface to be cleaned.
• a second design form the so-called hand vacuum cleaner.
• the suction pipe is rigidly connected to the vacuum cleaner housing.
• engine, blower, electrical and filter unit are housed in the housing.
• This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
• the negative pressure generated by the motor and blower is applied to the surface to be cleaned.
• These are usually either hard, smooth surfaces of floor coverings such as parquet, PVC, stone, etc., or textile surfaces such as carpets, furniture upholstery or the like.
• the different nature of the surface sometimes places conflicting demands on the functionality of the floor nozzle.
• rollers are often arranged in the bottom of the vacuum cleaner floor nozzles, with two front floor rollers are provided at an identical distance from the front edge of the floor nozzle. If you push such a vacuum cleaner bottom nozzle perpendicular to an edge, the rollers contact this edge substantially simultaneously; This results in an abrupt overcoming of the edge through the vacuum cleaner nozzle, which requires an undesirable force and leads to an undesirable rattle, especially on hard surfaces.
• the invention has for its object to provide a Staubsauger Camilldüse available, which eliminates the problems of Fugenklappems and simultaneously has good frontal care properties.
• the invention is based on the generic Staubsauger foundeddüse in that the first bottom roll is arranged in front of the suction mouth and the second bottom roll is arranged behind the suction mouth.
• the advantageous concept of providing different spacings of the floor rolls from the front edge of the floor nozzle is combined with a space-saving arrangement of the rolls.
• This space saving concerns in particular the front of the suction mouth required for the accommodation of a roll Area. Since the second roller is arranged behind the suction mouth, this area can be made very small in front of the suction mouth.
• the suction mouth in the region of the first bottom roll has a greater distance from the front edge than in the region of the second bottom roll.
• the greater distance from the leading edge in the area of the first roller serves to accommodate the first roller. Since this greater distance in the region of the second roller is not required, the suction mouth can approach in the area of the second roller of the leading edge, so as to provide good Frontalsaugeigenticianen.
• this can be realized in that the suction mouth to provide the different distances has a curvature.
• the suction mouth for providing the different distances has a recess in which the first bottom roll is arranged.
• the invention is further developed in a particularly advantageous manner in that further bottom rollers are arranged behind the first and the second bottom roller, which have the same distance from the front edge.
• further bottom rollers are arranged behind the first and the second bottom roller, which have the same distance from the front edge.
• the rear rollers it is useful to equip them with the same distance from the front edge, since this improves the sliding properties of the vacuum cleaner floor nozzle. Since the rear rollers are designed to be much larger than the front rollers, they slide easily over bumps in the ground anyway.
• Figure 1 is a perspective view of a vacuum cleaner floor nozzle according to the invention with a view of its upper side;
• Figure 2 is a perspective view of a Staubsauger Camilldüse according to the invention with a view of its underside; and Figure 3 is a plan view of the underside of a Staubsaugerêtdüse invention.
• FIG. 1 shows a perspective view of a vacuum cleaner nozzle 10 according to the invention with a view of its upper side.
• FIG. 2 shows a perspective view of a vacuum cleaner floor nozzle 10 according to the invention with a view of its underside
• FIG. 3 shows a plan view of the underside of a vacuum cleaner floor nozzle 10 according to the invention.
• the vacuum cleaner floor nozzle 10 has a front edge 16 extending transversely to the main movement direction of the vacuum cleaner floor nozzle 10
• Staubsauger convinceddüse 10 are controls 26, 28 are arranged, which can serve, for example, the raising and lowering of a bristle strip 28.
• the Staubsauger convinceddüse 10 can connect to a suction pipe of a vacuum cleaner.
• the Saugrohrstutzen 10 opens into a provided in the Staubsauger foundeddüse 10 suction channel 12, which in turn ends in an open-suction port 14.
• Four floor rollers are arranged on the vacuum cleaner floor nozzle 10, namely two front floor rollers 18, 20 and two rear floor rollers 22, 24.
• the rear floor rollers 22, 24 are at the same distance from the front edge 16 of the vacuum cleaner floor nozzle 10.
• the front bottom rollers 18, 20 at different distances from the front edge 16.
• the first floor roller 18 has a smaller distance from the front edge 16 than the second floor roller 20. In order to keep the area required for accommodating the floor rollers 18, 20 as small as possible in front of the suction mouth 14, only the first floor roller 18 is in front of the suction mouth 14 arranged.
• the second bottom roll 20 is placed behind the suction mouth 14.
• the suction mouth 14 is curved, that is to say it has a smaller distance in the region of the second bottom roll 20
• a further narrowing of the suction mouth 14 is provided in the area of the first floor roller 16 Also may be referred to as a recess or partial recess of the suction mouth.
