Definitions

  • the invention relates to a floor nozzle for a vacuum cleaner, with a housing which has a sole facing the floor surface in the processing position, a suction mouth being arranged in the sole, the suction mouth passing through a rear area of the sole, a front area of the sole and side areas the sole is included as well as a vacuum cleaner with such a floor nozzle.
  • Vacuum cleaners are used in private households and businesses to clean surfaces such as textile floor coverings and smooth floors.
  • a floor nozzle of the vacuum cleaner is continuously pushed back and forth on a floor surface.
  • the dust collection effectiveness of the vacuum cleaner depends heavily on the design of the floor nozzle.
  • a floor nozzle with a sole on the sole that is flat along the suction mouth has the disadvantage that when the floor nozzle moves backwards in the processing direction when cleaning long-pile surfaces, the carpet is partially lifted off the floor surface by the user pulling back the floor nozzle.
  • the carpet to be cleaned is lifted in the area of the highest negative pressure, usually in the middle of the elongated suction mouth, while the carpet remains on the floor at the outer ends of the elongated suction mouth due to the lower negative pressure.
  • the slightly curved soles do not comb the carpet to be cleaned in the middle of the suction mouth due to the lack of contact with the floor due to the larger distance, and on the other hand, this lack of contact with the floor leads to a drop in the negative pressure present at the floor nozzle to an area in which optimal cleaning is possible is no longer possible.
  • the design of the floor nozzle is playing an increasingly important role.
  • the dimensioning of vacuum cleaner fans follows a trend towards less power, which initially leads to lower volume flows available at the floor nozzle, so that lower flow velocities generally result at the floor nozzles due to the continuity relationship.
  • the soles of the floor nozzles are also designed to be movable to ensure an optimal cleaning effect.
  • a floor nozzle for a floor care device in which the sole with the sliding sole can be tilted and moved in several directions in order to compensate for uneven floors and to ensure better floor contact.
  • the mobility of the sole is limited by stops and the adaptability of the rigid sole is limited.
  • a floor nozzle for a floor care device in which individual areas of the sole can be moved in order to compensate for floor contours and to seal the suction mouth from the environment.
  • the mobility of the sole is limited by the degrees of freedom in the positioning of the individual areas.
  • the manufacturing effort for such a floor nozzle is relatively high.
  • the invention therefore faces the problem of providing an improved floor nozzle and an improved vacuum cleaner.
  • the floor nozzle can optimally adapt to floor contours during cleaning operation. This means that even with low volume flows, effective cleaning of the floor surface can be achieved with sufficiently high flow velocities.
  • the dust collection effectiveness - especially on carpets - can be advantageously increased, so that good performance classes or dust collection values can be achieved even at low absorption levels.
  • the suction mouth which rests better on the surface, can clean a wide area of the floor surface with a significantly higher flow rate, without the need for higher volume flows.
  • the deformable sole nestles against the floor bellows so that the suction mouths or the suction mouth are at least almost close to the floor covering.
  • the dust collection effectiveness can thereby be increased without there being a significant increase in the pushing forces.
  • the volume flow required for effective cleaning can be further reduced, so that more economical blowers can be installed in the vacuum cleaner.
  • the reduction in volume flows also leads to lower flow losses, especially in bagless separators, so that further energy can be saved here.
  • the floor surface can be replaced by a textile floor covering such as a carpet or carpet or by a hard floor such as. B. a wooden parquet, laminate or a PVC floor covering can be formed.
  • the vacuum cleaner can have a blower to generate a negative pressure, through which the floor nozzle, which is guided over a floor surface to be cleaned, picks up dust and dirt from the floor surface.
  • the user moves the floor nozzle back and forth in the processing direction using pushing and pulling movements. This allows the floor nozzle to slide over the floor surface to be cleaned.
  • the sole of the floor nozzle slides over the carpet, while in the case of hard floors the sole floats at a distance over these floor surfaces, if necessary using spacer bristles.
  • the user can, for example, handle a handle of the vacuum cleaner that is connected to the suction tube.
  • the suction mouth is elongated and runs essentially transversely to the processing direction.
  • Elongated in this context means that the preferably substantially rectangular suction mouth area has a greater length transverse to the processing direction than its width in the processing direction.
  • the suction mouth area is preferably between 20 and 30 cm long transversely to the processing direction and preferably between one and 3 cm wide in the processing direction.
  • the floor nozzle can also be arranged on a self-driving vacuum cleaner, in particular a vacuum robot, so that the processing direction of the floor nozzle corresponds to the direction of travel of the self-driving vacuum cleaner.
  • a vacuum cleaner housing of the vacuum cleaner can have a dust collection chamber in which the dust picked up via the floor nozzle can be collected, for example in a dust bag.
  • the front region of the sole is designed to be deformable.
  • the deformable design of the rear area, the front area and the side areas of the sole enables the sole to be optimally adapted to its approximate shape entire floor area. This means that the suction mouth of the floor nozzle is sealed from the environment in all directions during cleaning operation.
  • the sole is made of an elastic plastic. It is conceivable to form the sole in one piece from an elastic plastic material. This is particularly advantageous in terms of the resulting manufacturing effort and homogeneous deformability over the entire surface of the sole. In an alternative embodiment, it is also conceivable to make the sole from different plastic materials with different properties in terms of deformability, hardness or friction. This means that specific deformation properties can be set in individual areas of the sole in order to further improve the cleaning performance.
  • the sole or sole is constructed in several parts, the individual members of the sole being designed to be pivotable relative to one another.
  • a multi-part sole allows the floor nozzle to adapt excellently to the surface.
  • the sole is also adaptable to changing conditions when the floor nozzle moves forwards and backwards. This adaptability is very easily ensured by the fact that the individual members of the sole are designed to be pivotable relative to one another.
  • the links are each designed to be pivotable relative to one another about a joint axis that runs parallel to the processing direction. Thanks to the joint axes running parallel to the processing direction, the links can be easily adjusted to the surface. The joint axes running in this way prevent movement of the links in the processing direction, so that the edges of the suction mouth delimiting the suction mouth can effectively process the subsurface. The edges of the suction mouth comb the carpet fibers, especially in long-pile carpets, and thus enable the fibers to be cleaned thoroughly.
  • a preferred embodiment provides that at least one member is designed to be pivotable from the rest position in the direction of the floor surface.
  • the possibility of pivoting a link from the rest position towards the floor surface enables a simple but effective adjustment of the floor nozzle to the surface to be cleaned and the changing conditions during forward and backward movement in the processing direction.
  • the development is particularly advantageous in that the sole is constructed in two parts with a joint axis arranged centrally between the two parts.
  • Such a design is particularly characterized by its simple structure and good quality Adaptability of the floor nozzle to the surface to be cleaned.
  • the floor nozzle also optimally corrects the changing conditions when the floor nozzle moves forwards and backwards in the processing direction.
  • the sole is formed from members arranged symmetrically to the center of the suction mouth.
  • the arrangement of several links, which are symmetrical to the center, on the sole of the floor nozzle ensures even cleaning of the floor surface and a high degree of adaptability to the surface to be cleaned and the changing conditions when the floor nozzle moves forwards and backwards in the processing direction.
  • An advantageous embodiment of the invention provides that the links form at least one lateral edge on the sole.
  • the edge-side design of the sole using movable links creates improved adaptability of the floor nozzle to the surface and optimizes corner cleaning, for example on skirting boards or carpet edges.
  • the links are made of a solid plastic.
  • the links made of solid plastic provide a stable and lightweight sole that can be flexibly adapted to the floor being cleaned and the changing conditions when moving forwards and backwards.
  • a preferred embodiment provides that a hinge is formed between the links. Forming a hinge between the links is a simple but effective way to increase the adaptability of the floor nozzle.
  • the hinge defines the joint axis between the two links connected by the hinge.
  • a spring element is arranged between the links, which causes a restoring force that moves the links back into a rest position.
  • the arrangement of a spring element between the members in this way ensures that the floor nozzle is optimally adapted to the floor surface to be cleaned and the changing conditions during forward and backward movement. Lifting the floor nozzle from the ground causes the sole of the floor nozzle to move back to a rest position.
  • an elastomer is arranged as a hinge between the links. Arranging an elastomer as a hinge provides a simple but solid possibility of providing a tight and at the same time adaptable hinge between the links. With this seal between the members it can be effectively achieved that the volume flow available through the blower still flows through the suction mouth formed.
  • the development is particularly advantageous in that the elastomer causes a restoring force that moves the links back into a rest position.
  • a restoring force can also be created, which enables the floor nozzle to be optimally adjusted. If the floor nozzle is lifted from the ground, the elastomer causes the sole of the floor nozzle to move back to a rest position.
  • a preferred embodiment provides that the sole is made of elastic plastic.
  • the design of the sole made of an elastic material offers a particularly adaptable floor nozzle.
  • the suction mouth edge is designed to be deformable with the suction mouth.
  • a suction mouth edge that can be deformed with the suction mouth improves the adaptability of the floor nozzle to the surface to be cleaned and ensures that long-pile carpets in particular are optimally cleaned by the suction mouth edges both in the forward and backward movement of the floor nozzle in the processing direction.
  • This arrangement also offers the advantage that no areas of the surface to be cleaned are left out.
  • a sharp-edged design of the suction mouth edge ensures that the fibers of the carpet pile are effectively bent. This only increases the sliding resistance on the floor surface minimally, as the suction mouth edge, which is adapted to the surface, effectively bends the carpet open.
  • the deformable suction mouth edge effectively bends the carpet fibers over the entire suction mouth area without the user having to exert excessive force during the advance and retraction movements.
  • the underside of the sole in the starting position or in the resting state, extends straight or at least essentially straight transversely to the processing direction.
  • the outer sides of the sole deform downwards in relation to the central area of the sole, creating a curvature in the shape of an upside-down U when viewed from the front.
  • all direction and position information relates to the correct use of the floor nozzle.
  • the subject of the invention is a vacuum cleaner for cleaning and caring for floor surfaces with a fan for generating a negative pressure for picking up dirt by means of an air stream and a separation system for cleaning the picked up air from dirt, the vacuum cleaner already described in more detail below having a floor nozzle according to the previous and following description.

  • the telescopic suction tube 22 merges into a handle 23, to which a suction hose 12 is connected, which is connected to the vacuum cleaner housing 17, 17a.
  • a blower (not shown) of the vacuum cleaner 2 integrated in the vacuum cleaner housing 17, 17a is operated with electricity via an electrical connection cable 18 in order to generate a negative pressure.
  • dirt and grime are removed from the floor surface 24 ( Fig. 4 ) by an air flow via the suction mouth 6 ( Fig. 5 ) of the floor nozzle 1 and transported via the suction pipe 22 and the suction hose 12 into the housing 17, 17a of the vacuum cleaner 2.
  • a separation system 20 is provided in this housing 17, 17a, which in the exemplary embodiment is designed as a dust bag. This separation system 20 is located in a dust chamber 21 formed by the housing parts 17 and 17a of the vacuum cleaner 2.
  • This dust chamber 21 is accessible and shown open by a folding mechanism between the vacuum cleaner housing parts 17 and 17a, so that the separation system 20 is visible and removable.
  • the dust chamber 21 is closed and a negative pressure is generated.
  • the air flow generated by the negative pressure is freed from dirt and grime in the separation system 20 and led out of the vacuum cleaner 2 via an exhaust air grille 19.
  • the step switch 14 usually also has a switch for actuating the automatic winding system for the connecting cable 18 (not shown) integrated in the vacuum cleaner housing 17, 17a.

  • the sole 4 shown here is fixed via the suspension elements 26 in the housing 3 of the floor nozzle 1, not shown here.
  • the sole 4 consists of a soft, elastic plastic and is therefore movable along the entire spatial extent.
