Description

  The present invention relates to a floor cleaner provided with a rotating brush disposed in an air inlet of an apparatus cover and provided with a traveling roller for light operation.

  As a conventional floor cleaner, for example, an adapter connection device type for a household vacuum cleaner or a pipe-operated cleaner type is known. These comprise a rotating brush for rotary cleaning of the floor to be cleaned, for which reason the brush is in principle arranged perpendicular to the direction in which the user slides the device forward, and further a brush with a bunch of hair is provided in the device It protrudes downwards across the bottom. To lighten the operation, such a floor cleaner further comprises at least a running roller that supports the device on the floor to be cleaned.

  The prior art is described in Japanese Patent Application Laid-Open No. 05-228085, Japanese Patent Application Laid-Open No. 04-058926, US Pat. No. 4,660,247, and European Patent Publication No. 0523632. In the floor cleaner known from JP 04-058926 A, however, the running roller is arranged outside the brush in the direction of extension of the axis of the rotating brush. However, this does not provide the desired comfort of operation. In a floor cleaner known from Japanese Patent Laid-Open No. 05-228085, a brush is provided, and a drive wheel is provided that is substantially concentric with the brush and configured to divide the brush. Even with this, although certain improvements have been achieved, there are relatively many defects that spontaneously inhale the carpet material. The problem of the present invention exists from a vacuum cleaner known from the last cited document, and is to make the vacuum cleaner of the technology cited at the beginning comfortable.

  This problem is first and substantially solved by the invention according to claim 1, wherein the traveling roller is disposed in the air inlet and penetrated by the brush, and the traveling roller is provided with a guide configured as a slide guide. . It is shown that there is an advantage in terms of improved intake on the front side or brush cleaning, since the inlet through which the brush or brush is penetrated can thereby be located closer to the front of the floor cleaner.

  Rollers that do not move spontaneously are therefore less likely to spontaneously inhale carpet material. As a result, the sliding stress is also reduced in the brush cleaning and suction cleaning of the carpet. Preferably, the traveling roller and the brush are arranged substantially concentrically with each other.

  Furthermore, the brush adjusts the defined bottom spacing according to the configuration of the running roller according to the invention. In this connection, the running roller further comprises a guide with a brush through-hole formed therein, and the guide is preferably around the running roller, preferably for example 25-75%, more preferably It is configured to spread over only a part of the periphery, such as about 30%. This guide determines the geometric axis of the travel roller. Furthermore, in this connection, the guide extends over the lower periphery during operation of the floor cleaner. In one embodiment, the traveling roller guide is held in a direction perpendicular to the rotational axis of the traveling roller, particularly in a part of the apparatus case. Further, the holding may be performed by a part of the brush or a part of the intake chamber.

  In a preferred refinement of the invention, the guide is formed with an arc frame in which the traveling roller moves simultaneously relative to the arc frame. The guide further extends over a part of the periphery of the traveling roller, and an arc frame in which the ring-shaped traveling roller is guided radially outward is formed in a cylindrical shape. The latter (traveling roller) penetrates the guide at a support portion extending radially outward. This support simultaneously serves as a guide or holding of an arc frame that guides the running roller. An opening portion of the support portion that is penetrated by the traveling roller is configured such that the traveling roller is interlocked with the guide.

  In a preferred embodiment, the guide forming the arc frame may be configured such that a portion extending radially outward contacts the traveling roller, and may be penetrated by the traveling roller in a part of the support portion. The opening in the support portion has a matching cross-sectional shape and can rotate in the latter direction with respect to the circumferential curvature of the traveling roller, but the shaft of the traveling roller is both in the axial direction of the traveling roller and in the direction perpendicular thereto. You can pass through to hold. The brush has a brush support and a bunch of brush hairs extending radially therefrom. In this connection, the through hole of the traveling roller is set to be larger than the diameter of the brush support but smaller than the outermost diameter of the bristles of the brush. Therefore, the brush may be held without hair in the through-hole portion so as to fit around the circumference of the traveling roller. As a condition that the through-hole of the traveling roller is set to be smaller than the outermost diameter of the bristles of the brush, it is guaranteed that the traveling roller is supported on the carpet or the floor brush is cleaned. Is done.

  Further, the through hole of the traveling roller is adjusted so that a brush (for example, responding to the unevenness of the floor) arranged to move in a tilting manner can freely move within the through region of the traveling roller. The arrangement of the running rollers may also be achieved by a floating roller in which a ring-shaped running roller is held by a roller on its inner wall. Alternatively, the travel roller may be supported without a shaft on its outer periphery. Such a support may be configured in the form of roller bearings or cylinder bearings to form a rotary guide or an external slide guide. In one refinement, a plurality of, preferably three, equal and mutually spaced supports are provided over the outer periphery of the ring-shaped running roller, which is the roller bearing or The cylinder bearing is held inside the apparatus, preferably inside the brush or the intake chamber.

  The invention will be described in more detail on the basis of the accompanying drawings which illustrate only the following two examples.

  First, referring to FIG. 1, a floor vacuum cleaner type household vacuum cleaner 1 guided to a floor cleaner 5 via a suction hose 2 and an operation pipe 3 for sucking and cleaning the floor 4 is shown and described. . The latter (floor cleaner 5) is configured as an adapter device to the vacuum cleaner 1 that can be connected to the vacuum cleaner 1 via a connector 6 both electrically and in airflow.

  The connector 6 is a front intake chamber 7 (with respect to the normal operation direction r) and extends in a direction perpendicular to the operation direction r in the floor cleaning machine 5, downward, ie towards the floor 4 to be cleaned. It is located where it is fluidically connected to what forms a slit-like inlet 8 for dexterity.

  In the intake chamber 7, a brush 9 that can be driven and rotated by an electric motor and that extends in the direction orthogonal to the operation direction r and extends across the width of the intake chamber is disposed. The bunch of hairs 19 of the brush 9 protrudes downward for cleaning the floor 4 through the air inlet 8 over the apparatus bottom 11.

  As can be seen in particular in the bottom view shown in FIG. 2, the floor cleaning machine 5 is fixed in the device case 13 in the usual manner at the rear, ie at the tip of the connector 6, and rotates around the axis 14. It is configured to have travel rollers 12 arranged in a possible manner.

  Further support is provided to the floor cleaner 5 in the front part with respect to the operating direction r, in particular inside the air inlet 8 which is penetrated by the brush 9 or the bristles 19 of the brush hair.

  Here, a traveling roller 15 is further provided so as to be penetrated by these in a concentric manner with respect to the direction in which each brush 9 extends.

  FIGS. 3 to 7 show a first embodiment of the traveling roller 15 arranged in the front part of the floor cleaning machine 5. First, a through-hole 17 for each brush 9 is formed, which is larger than the diameter d of the brush support 18, but smaller than the diameter of the bundle of brush hairs 19 extending radially from the brush support 18. A guide 16 is provided (see FIG. 3). A brush support 18 is held without a brush in an axial cross section where the traveling roller 15 is located. The geometric rotation axis of the traveling roller 15 is determined by the guide 16.

  The guide 16 extends for only a part of the peripheral edge of the traveling roller 15, for example, about one third of the peripheral edge in the illustrated embodiment, and at the same time for the traveling roller 15 having a basically ring shape. An arc frame 20 is formed. The arc frame 20 having a cylindrical cross-sectional shape is formed with support portions 21 extending outward in the radial direction and penetrated by a ring-shaped traveling roller 15 at both ends.

  The guide 16 formed in this way is configured to contact the lower portion of the traveling roller 15 in the operating state of the floor cleaner 5. Thus, the traveling roller 15 is supported inside the wall of the arc frame 20, and the outer diameter of the arc frame 20 is smaller than the outer diameter of the traveling roller 15.

  The guide 16 is held in a direction orthogonal to the rotational axis of the traveling roller 15 by the support portion 21 protruding in the substantially radial direction, and the support portion 21 is fixed in the apparatus case 13, particularly in the intake port 7. Yes.

  The arrangement and fixing of the guide 16 are further set such that the arc-shaped portion of the traveling roller 15 protrudes below the apparatus bottom 11.

  The ring-shaped traveling roller 15 is interlocked by a guide 16, and therefore the ring-shaped traveling roller 15 has a substantially double T-shaped cross-sectional shape. The support portion 21 pierced by the traveling roller 15 has a cross-sectional shape and has a through hole 22 opened in the direction of the thickness of the support portion 21 with the curvature of the arc of the traveling roller 15 (FIGS. 6 and 6). 7).

  As a result of this configuration, the traveling roller 15 is interlocked with the guide 16 so as to freely rotate. The support of the floor cleaning machine 5 by the traveling roller 15 and the upper support of the floor cleaning machine 5 are configured so that the traveling roller 15 does not shift relative to the guide 16 in a direction perpendicular to the rotation axis.

  Therefore, it is a condition that the guide 16 is formed over only a part of the periphery of the traveling roller 15, and the through-hole 17 that is penetrated by the brush 9 is concentric with the arc frame 20 and the ring-shaped traveling roller 15. It consists of an opening. The inner diameter of the through hole 17 is about 1.2 to 1.5 times the diameter d of the brush support. The diameter of the bristles 19 of brush hairs extending in the radial direction from the brush support 18 is set so that the open end protrudes over the outer surface of the traveling roller.

  As a result of the improvement according to the invention, the travel roller 15 has a dual function. They therefore serve on the one hand for light operation and on the other hand as a lower support inside the inlet 8. In particular, lightly aspirated by the low pressure generated in the air inlet 7, which in turn closes the air inlet 7, thereby creating a sliding stress. Is done.

  Another embodiment for fixing the shaft of the traveling roller 15 is shown in FIGS. In these traveling rollers 15, concentric openings formed by ring-shaped elements of the traveling rollers 15 simultaneously form the through-holes 17 for the brush 9 and are configured without an axis. The running roller 15 is supported by these outer peripheral portions. For this reason, bearings 23 that function integrally with the edge portions 24 captured by the running roller 15 are provided on both sides of the running roller 15 in the rotational direction. Yes. Thereby, the bearings 23 are arranged at an angle of about 45 ° with respect to the flat surface of the traveling roller 15, and preferably three bearing pairs around the periphery of the traveling roller 15, each being 120 degrees from each other. It is provided so as to make an angle of Thus, the bearing 23 is held in a part of the device case 13, particularly in the air inlet 7.
