Description

  The present invention relates to a suction tool that is attached to an extension pipe extending from a vacuum cleaner main body of a vacuum cleaner and cleans a surface to be cleaned.

  Conventionally, so-called inclined piles in which the tips of brush hairs are inclined are used for clothes brushes. In recent years, a technique has also been disclosed in which the inclined pile is disposed on a suction tool that is attached to an extension pipe extending from a vacuum cleaner body of a vacuum cleaner and cleans the surface to be cleaned. As such a technique, for example, a dust collection suction chamber is provided in the suction tool body, and a first suction port and a second suction port that communicate with the dust collection suction chamber are provided at the front and back of the bottom surface of the suction tool body. In addition, a brush is provided between the first suction port and the second suction port, and a tip end portion of the brush located in the vicinity of the first suction port is directed toward the first suction port, so that the second suction port is provided. There is a suction tool in which the tip of the brush located in the vicinity of the mouth is directed toward the second suction port (see Patent Document 1).

However, in the conventional suction tool, since the brush is not provided over the entire width of the suction tool body, dust at the wall cannot be effectively removed, and a suction tool with improved points has been desired.

At the bottoms of the brush body mounting portions 42 and 43, mounting holes 42a communicating with the dust collection suction chamber are formed at both ends, respectively, and two fitting holes 42b and 42b are formed on the left and right sides near the center. Yes. Further, notches 45 and 45 are respectively formed in the center portions in the width direction of the vertical walls 44 and 44 that define the lateral groove 41 and the brush body attaching portions 42 and 43.

  The brush body attaching portions 42 and 43 are mounted with thin plate-like brush bodies 47 and 48 over the entire width in the width direction of the brush body attaching portions 42 and 43. As shown in FIG. 5, the brush bodies 47 and 48 include a thin plate-like base 51 and a pile 52 having brush hairs covering the entire surface from the peripheral edge of the back surface of the base 51. It is affixed to the base 51 using an agent, an adhesive tape, or the like. The front ends of the brush bristles constituting the front and rear brush bodies 47 and 48 are inclined toward the lateral groove 41. That is, the brush bodies 47 and 48 disposed before and after the lateral groove 41 constitute an inclined pile.

  At both ends of the back surface of the base portion 51 of the brush bodies 47 and 48, hook projections 53 and 53 whose tips are bent outward in the longitudinal direction of the brush bodies 47 and 48 are erected, and the fitting projections are closer to the center portion. 54 and 54 are erected. The base 51 is formed of a flexible synthetic resin, and one hooking protrusion 53 is inserted into one mounting hole 42a of the brush body mounting portion 42 (43), and then the central portion is higher than both ends.

Finally, by fitting the fitting protrusions 54, 54 into the fitting holes 42b, 42b, the brush bodies 47, 48 are detachably attached to the brush body attachment portions 42, 43, respectively.

  The lower case 4 has a front surface formed continuously from the upper edge of the front wall of the front brush body mounting portion 42 and is connected from the upper edge of the rear wall of the rear brush body mounting portion 43. A back surface is formed, and openings 61 and 62 communicating with the dust collection chamber are formed on the front surface and the back surface, two on each side. Further, front edge fabrics 63, 63 made of fluororesin having excellent slipperiness are attached to the side portions closer to the center of the front openings 61, 61 from the upper end to the lower end. Further, rollers 64 and 64 are rotatably attached to the back surface.

  The side surface of the upper case 3 constitutes a bumper projecting outward as compared to the lower case, and is stuck with a raised cloth 65 from the periphery of the back surface to the entire surface. The raised cloth 65 is not particularly limited as long as it has a buffering capacity that does not damage furniture or the like when the suction tool 1 hits furniture or a wall or the like at the time of cleaning. For example, a silk-like cloth made of polyester is used. A brushed cloth or the like is preferably used.

  When using the suction tool 1 configured as described above, first, the connection pipe 5 is attached to an extension pipe extending from a vacuum cleaner main body (not shown). And after driving a vacuum cleaner and making a negative pressure act on the said dust collection suction chamber, the bottom face of the lower case 4 is applied to to-be-cleaned surfaces, such as a flooring, a folding, and a deuteron, and the suction tool 1 is moved back and forth Let When the suction tool 1 is pushed forward, the rear brush body 48 captures dust and the like, and when the suction tool 1 is pulled rearward, the front brush body 47 captures dust and the like. The trapped dust and the like are sucked into the dust collection suction chamber through the suction port 41a of the lateral groove 41, and thereby dust and the like are removed.

  In the present invention, the brush body mounting portions 42 and 43 that are recessed in the width direction from both side surfaces to the bottom surface of the lower case 4 constituting the suction tool main body 2 span the entire width in the width direction of the brush body mounting portions 42 and 43. Since the brush bodies 47 and 48 are attached, dust and the like near the wall can be efficiently removed. The lower case 4 is recessed in the width direction from both side surfaces to the bottom surface, and a suction port 41a communicating with a dust collection suction chamber provided in the suction tool body 2 is formed in the recessed bottom portion. Since the gap is always formed between the suction port 41a and the carpet even when the surface to be cleaned is a carpet, the dust collected in the horizontal groove 41 can be used without waste. Thus, dust and the like can be efficiently removed.

  Since the entire surface of the upper case 3 is stuck with the raised cloth 65, the suction tool 1 does not damage furniture or the like even if the upper case 3 hits the furniture or the wall during cleaning. Furthermore, even when moving back and forth with respect to a surface to be cleaned with undulations or steps, the front edge fabric 63 with excellent slipperiness is stuck, so that it can smoothly run up and down the undulations and steps. Can do.

  The openings 61 and 62 are formed so as not to apply a load to the drive motor of the vacuum cleaner when the clearance between the surface to be cleaned and the lateral groove 41 decreases due to some trouble during cleaning. In the present invention, since two openings 61 and 62 are formed on the front and rear surfaces of the lower case 4 respectively on the left and right sides, air is evenly supplied from the front, rear, left and right through the openings 61 and 62 during cleaning. Since the flow flows in, the operability can be improved without moving the suction tool 1 back and forth.

  When the suction tool 1 is used for a long period of time, the dust trapping performance of the brush bodies 47 and 48 is lowered. Therefore, in the present invention, it is preferable to prepare another brush body as a spare and replace the brush bodies 47 and 48 after a predetermined period has elapsed. At this time, for example, the brush bodies 47 and 48 can be easily removed by inserting the tip of a minus driver into the notch 45. That is, when the tip of a flathead screwdriver is inserted into the notch 45, the tip contacts the back corners of the brush bodies 47 and 48. Therefore, when the grip handle of the minus driver is lowered in this state, the engagement state between the fitting protrusion 54 and the fitting hole 42b, and the hooking protrusion 53 and the mounting hole 42a is released, thereby the brush body 47. 48 can be easily removed.

  Moreover, when the photocatalyst (titanium oxide) and silver ions are fixed to the bristle by a known method such as a dipping step and subsequent drying step, antibacterial action and deodorizing effect are exhibited, and the bristle is kept clean for a long time. be able to.

  Although the present invention has been described in detail above, the present invention is not limited to the above embodiment, and the size, shape, number, and the like of each member can be changed as appropriate without departing from the spirit of the present invention. .
