JP 2005-329209 A

  In the conventional attachment for a vacuum cleaner, the periphery of the suction port is surrounded by a brush. When a flat surface to be cleaned is swept with such an attachment for an electric vacuum cleaner, the dust picked up by the brush may not be smoothly sucked into the suction port. For example, in a conventional attachment for a vacuum cleaner, when the brush is pressed against a flat surface to be cleaned, the frame and the brush are appropriately tilted, and all of the brush tips contact the surface to be cleaned substantially uniformly. Is done. When the conventional vacuum cleaner attachment is moved in this state, the dust swept by the brush may not be smoothly moved to the suction port side, and may be swept away from the suction port.

  On the other hand, a conventional vacuum cleaner attachment in which a part of the periphery of the suction port is surrounded by a brush, for example, a conventional attachment for a vacuum cleaner in which the periphery of the suction port is surrounded by a U-shape is brushed. It is convenient for sweeping up the dust in front of the suction port (opposite direction of the air flow sucked into the suction port), but the flow passage cross-sectional area around the suction port is large, and the flow velocity of the sucked air decreases. For this reason, the power to suck in the dust collected is inferior.

  That is, the conventional attachment for a vacuum cleaner provided with a frame and a brush that are actively adjusted in posture so that all of the brush tips sweep the surface to be cleaned substantially uniformly. It has been difficult to achieve both ease of sweeping and the ability to suck in dust that has been swept up.

  The present invention proposes an attachment for a vacuum cleaner, a suction port, and a vacuum cleaner that can achieve both the ease of dust collection on the surface to be cleaned and the force to suck in the dust collected.

In order to solve the above problems, an attachment for a vacuum cleaner according to the present invention includes a cylindrical connecting pipe portion having openings at both ends, and an outer peripheral edge portion of one of the openings in the first half in the traveling direction of the connecting pipe portion. A pair of brushes that divide and surround each of the part side and the latter part side by approximately half a circumference, and the latter part side of the brush is implanted so that the tip of the brush on the latter part side substantially uniformly contacts the surface to be cleaned. And a rear half frame body pivotally supported at one end of the connecting pipe portion so as to be in contact with each other.

  Further, a suction port body according to the present invention includes a main body portion having a suction port, a connection pipe portion provided in the main body portion, and the attachment for the vacuum cleaner that is detachably fitted in the connection pipe portion. , Provided.

  Furthermore, the vacuum cleaner according to the present invention includes a vacuum cleaner body, a dust collection hose communicated with the vacuum cleaner body, an extension pipe communicated with the dust collection hose, and an end of the extension pipe.

  FIG. 5 is a partial cross-sectional view showing an end of the attachment according to the embodiment of the present invention on the suction port body side.

  FIG. 6 is a perspective view showing a first frame and a second frame of the attachment according to the embodiment of the present invention.

  As shown in FIGS. 5 and 6, the first frame 33 and the second frame 34 of the attachment 28 are each formed in a substantially U-shape, and a frame main body that is annular as a whole when the respective open ends are attached to each other. 33a and 34a are provided. Further, the first frame body 33 and the second frame body 34 are pivotally supported at the open ends of the respective frame main bodies 33a and 34a so as to be independent from each other with respect to the connecting pipe portion 31, and to each other. A pair of hinge mechanisms 51 that are pivotably supported relatively is provided.

  The pair of hinge mechanisms 51 have tilting axes that are positioned on the same line. Specifically, the hinge mechanism 51 includes, for example, a shaft portion 51a and a shaft portion 51b provided in the first frame body 33, an arm portion 51d provided in the second frame body 34 and having a shaft hole 51c, Is provided. The shaft portion 51 a pivotally supports the first frame 33 in the shaft hole 48 of the connecting tube portion 31. The shaft portion 51b is disposed on substantially the same axis as the shaft portion 51a. The arm portion 51d causes the first frame 33 to pivotally support the second frame 34 by the shaft portion 51b pivotally supported by the shaft hole 51c.

  Note that the shaft hole 48 of the connecting pipe portion 31, the shaft portion 51 a and the shaft portion 51 b of the first frame body 33, and the shaft hole 51 c of the second frame body 34 are connected to the first frame body 33 and the first frame body 31. The combination of the shaft and the hole may be appropriately changed as long as the two frame bodies 34 can be pivotally supported independently of each other. Further, both the first frame body 33 and the second frame body 34 may be directly supported by the connecting pipe portion 31.

  The frame main body 34 a of the second frame 34 is formed thicker than the frame main body 33 a of the first frame 33. As a result, the root of the second brush 37 is raised, and the first brush 36 has a longer leg than the second brush 37.

  The first brush 36 and the second brush 37 are each formed by a frame body 33a, 34a formed in a U-shape and a hinge mechanism 51 provided at an open end of the frame body 33a, 34a. As the distance from the tilt axis of the second frame 34 increases, the hair bundles 35a arranged on a line parallel to the tilt axis increases and the waist (elasticity) of the entire brush becomes stronger. In other words, the partial rigidity of the first brush 36 and the second brush 37 increases as the distance from the tilt axis of the first frame 33 and the second frame 34 increases.

  Next, the cleaning operation of the electric vacuum cleaner 1 according to the present embodiment will be described.

  The user of the electric vacuum cleaner 1 first connects the dust collecting hose 3, the extension pipe 7, and the suction port body 8 to the cleaner main body 2 in an appropriate order.

  Next, the power cord 16 is pulled out from the cleaner body 2, and the power plug 23 is connected to an outlet (not shown) for supplying commercial power.

  Next, the user of the vacuum cleaner 1 operates the start switch 26 while holding the holding part 5. Then, the electric blower 12 operates according to the operation mode set by the start switch 26.

  Next, the user of the vacuum cleaner 1 reciprocates the hand operating tube 4 and the extension tube 7 back and forth while holding the grip portion 5. Then, the suction port body 8 travels back and forth on the surface to be cleaned. At this time, the vacuum cleaner 1 sucks dust on the surface to be cleaned together with air into the suction port of the suction port body 8.

  The dust-containing air sucked into the suction port body 8 sequentially passes through the extension pipe 7, the hand operation pipe 4 and the dust collecting hose 3, and then sucked into the cleaner body 2.

  Dust contained in the dust-containing air is collected by the dust separating and collecting unit 14 accommodated in the cleaner body 2.

  The air from which the dust has been separated further passes through the electric blower 12 and is exhausted from the exhaust port of the cleaner body 2.

  And when cleaning the to-be-cleaned surface which is difficult to clean using the suction inlet body 8, for example, the narrow gap between the furniture where it is difficult to make the suction inlet body 8 enter, The user removes the suction port body 8 from the extension pipe 7. Then, the attachment 28 is in a usable state (FIG. 3).

  Next, the user of the vacuum cleaner 1 brings the hair tips of the first brush 36 and the second brush 37 of the attachment 28 into contact with the surface to be cleaned, and causes the attachment 28 to enter the gap.

  FIG. 7 is a perspective view showing an attachment according to the embodiment of the present invention.

  FIG. 8 is a cross-sectional view in the longitudinal axis direction showing the attachment according to the embodiment of the present invention.

  As shown in FIGS. 7 and 8, the attachment 28 of the vacuum cleaner 1 is operated by the operation force f on the surface F to be cleaned from the user of the vacuum cleaner 1 through the grip portion 5, the hand operation tube 4 and the extension tube 7. Pressed.

  Then, the first brush 36 and the second brush 37 that were initially pressed uniformly against the surface to be cleaned are gradually curved. At this time, since the second brush 37 has a shorter bristle and higher rigidity than the first brush 36, the operating force f is more actively shared. Further, the first brush 36 is not regulated by the tilt angle by the casing 32, and is tilted away from the surface to be cleaned F by the reaction force of the operating force f to be shared. Furthermore, since the second brush 37 has higher partial rigidity as it moves away from the tilt axis of the first frame 33 and the second frame 34, the operation force f is more actively shared as the part is further away from the tilt axis. However, the portion near the tilt axis is greatly bent by the operating force f. In FIG. 8, a portion where the hair bundle 35a of the first brush 36 and the second brush 37 is curved is indicated by a one-dot chain line.

  In this way, the first brush 36 and the second brush 37 mainly share the operating force f by the second brush 37, and the first brush 36 is cleaned by the difference in displacement due to the rigidity distribution of the second brush 37. Cause from face F.

  In this state, when the attachment 28 is caused to enter the gap, dust on the surface to be cleaned F passes through the gap formed between the first brush 36 and the surface to be cleaned F in the opening 44 of the connecting pipe portion 31. Guided downward. The dust is sucked from the opening 44 or is swept from the surface to be cleaned F by the second brush 37 and sucked from the opening 44. At this time, since the entire circumference of the opening 44 is surrounded by the brush 35 except for the gap formed between the first brush 36 and the surface F to be cleaned, the flow velocity of the air sucked from the opening 44 Can be sufficiently suppressed.

  At this time, the curved surface 52 a of the guide recess 52 is connected substantially continuously to the edge 31 c of the opening 44 of the connecting pipe portion 31.

  In addition, the attachment 28 has a hair tip of the second brush 37 substantially uniform in a state in which the user of the vacuum cleaner 1 holds the grip portion 5 and the extension tube 7 extends to the surface to be cleaned at an appropriate angle. Even if the second frame 34 is fixed at a tilting angle so as to come into contact with the surface to be cleaned, similar actions and effects can be obtained.

  According to the present embodiment, the first frame body 33 and the first brush 36, the second frame body 34 and the second brush 37 are made independent by pressing the tip of the brush 35 of the attachment 28 against the surface F to be cleaned. It is possible to form an appropriate gap between the first brush 36 and the surface to be cleaned F while reliably pressing the second brush 37 against the surface F to be cleaned. Thereby, the attachment 28 surrounds the opening 44 that is a suction port with the brush 35 as much as possible, and is to be cleaned existing in the traveling direction of the attachment 28 by the gap formed between the first brush 36 and the surface F to be cleaned. The dust on the surface F can be smoothly guided and can be reliably swept away from the surface F to be cleaned by the second brush 37. Therefore, the attachment 28 is not swept away in a direction in which the dust swept by the brush 35 moves away from the opening 44.

  In addition, according to the present embodiment, a gap formed between the first brush 36 and the surface to be cleaned F is opened in a state where the brush 35 is in contact with the surface to be cleaned, and dust on the surface to be cleaned F is opened. It is easy to configure as narrow as possible within a range that can be smoothly guided to 44, and thereby the flow velocity of air sucked into the opening 44 can be appropriately increased.

  Therefore, according to the embodiment of the present invention, it is possible to achieve both the ease of dust collection on the surface F to be cleaned and the force to suck the dust collected.
