It has become. The separation suction tool 9 mounting portion of the suction tool body 10 is formed with a convex portion 19 that fits into the lower surface intake port 13 in a state where the separation suction tool 9 is mounted.

  FIG. 3 is an external perspective view of the separation suction tool 9 according to the first embodiment of the present invention, and FIG. 4 is a sectional view of the floor suction tool 3 according to the first embodiment of the present invention.

  2 to 4, the separation suction tool 9 is provided with a front opening 12 at the front opening and a lower suction opening 13 at the lower opening, and the front suction opening 12 and the lower suction opening 13 are continuously opened from the front to the bottom. doing. When the separation suction tool 9 is attached to the suction tool body 10, the lower surface intake port 13 is closed by the convex portion 19.

  The suction tool main body 10 is provided with an opening 14 opened in the left-right direction in front of the lower surface, and an intake chamber 16 is formed in the suction tool main body 10 so as to communicate with the opening 14. A rotary brush 15 is disposed in the intake chamber 16 so as to face the opening 14, and the rotary brush 15 is rotationally driven by a motor (not shown) as a drive source. An intake port 17 is provided in a substantially central portion of the intake chamber 16, and the intake port 17 communicates with the front end intake port 12 of the separation suction tool 9 mounted on the suction tool body 10.

  The separation suction tool 9 is provided with illumination means for irradiating light toward the front of the separation suction tool 9 so as to face the lower surface inlet 13.

  As shown in FIGS. 5 and 6, the printed circuit board 21 is sandwiched between an inner tube 23 that forms an intake passage and a lower cover 24. The printed circuit board 21 is substantially hermetically isolated in a printed circuit board housing portion constituted by an inner tube 23 and a shielding wall 25 formed in the lower cover 24. A raised cloth 27 is disposed on the outer bottom surface of the lower cover 24.

  Illuminating means is disposed on the printed circuit board 21. An LED 22 is mounted on the printed circuit board 21, and a lens 18 is put on the tip of the LED 22. The lens 18 faces the lower surface intake port 13 and is substantially the same as the lower surface intake port 13 peripheral edge 20 or the lower surface intake port 13. It is formed so as to protrude slightly from the peripheral edge 20 to the lower surface inlet 13 side. The LED 22 is press-fitted with a dust intrusion prevention body 26 formed of urethane foam so as to cover the outer periphery of the LED 22, and the front end of the dust intrusion prevention body 26 is in close contact with the end face of the lens 18 and the separation suction tool 9 at the periphery of the lens 18. This prevents dust from entering between the lens 18 and the periphery of the lens 18.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The vacuum cleaner body 2 is connected to the floor suction tool 3 via the hose 6 and the extension pipe 4, and the electric blower of the vacuum cleaner body 2 and the motor of the floor suction tool 3 are driven to remove dust on the surface to be cleaned. Aspirate and clean up.

  When cleaning a narrow space such as a gap between furniture, the separation suction tool 9 is separated from the suction tool body 10 by lifting the extension pipe 4 while stepping on the separation suction tool attaching / detaching means 11 with a foot or the like. Do. When cleaning a narrow and dark place such as a gap between furniture, the LED 22 of the illuminating means is turned on in a state where the separation suction tool 9 is separated from the suction tool body 10, and cleaning is performed while illuminating the surface to be cleaned.

  By arranging the illumination means for illuminating the front position of the separating suction tool 9, the cleaning direction of the surface to be cleaned can always be stably illuminated regardless of the angle of the extension tube 4.

  Since the illumination means is disposed so as to face the lower surface inlet 13 of the separation suction tool 9, the surface to be cleaned does not come into contact with the lens 18 of the illumination means, and the outer surface of the lens 18 is damaged during cleaning. In addition, the impact on the illumination means can be reduced, and the reliability of the illumination means can be improved.

  In a state where the separation suction tool 9 is mounted on the suction tool body 10, the convex portion 19 formed on the separation suction tool 9 mounting portion of the suction tool body 10 fits into the lower surface inlet 13. In this state, the upper surface of the convex portion 19 is substantially the same height as the lower surface of the intake passage in the separation suction device 9, and the peripheral surface 20 of the lower surface intake port 13 of the separation suction device 9 is opposed to the convex portion 19. .

  Since the lens 18 of the illumination means is covered with the convex portion 19 in the state where the separation suction tool 9 is mounted on the suction tool body 10, the outer surface of the lens 18 is removed due to sucked dust or the like when cleaning with the suction tool body 10. Injury can be prevented. In addition, since the upper surface of the convex portion 19 is substantially the same height as the lower surface of the intake passage in the separation suction tool 9, and the peripheral surface 20 of the lower surface intake port 13 of the separation suction device 9 is close to and opposed to the convex portion 19, The step between the intake passage and the gap between the intake passage of the separating suction tool 9 and the convex portion 19 can be reduced, the suction airflow can be passed smoothly, and the generation of turbulence can be suppressed. Reduction and dust collection can be improved.

  By forming the outer surface of the lens 18 to be substantially the same surface as the peripheral edge 20 of the lower surface intake port 13 or slightly projecting from the peripheral surface 20 of the lower surface intake port 13 toward the lower surface intake port 13 side, the outer surface of the lens 18 and the outer surface and lower surface of the lens 18 It is possible to prevent fine dust from accumulating between the peripheral edge 20 of the air inlet 13 and when the fine dust adheres to the surface, the user can easily clean it. Further, dust or the like adhering to the outer surface of the lens 18 can be cleaned by the suction airflow when the separation suction tool 9 performs cleaning.

  In addition, by disposing the printed circuit board 21 in the printed circuit board housing part that is substantially sealed by the shielding wall 25, it is possible to prevent dust from entering the illumination means and to reduce malfunction due to static electricity.

  One end side of the dust intrusion prevention body 26 is press-fitted so as to cover the outer periphery of the LED 22, and the other end side of the dust intrusion prevention body 26 is brought into close contact with the lens 18 and the separation suction tool 9 at the periphery of the lens 18. It is possible to prevent dust from entering the LED 22 from between the periphery of the lens 18 and to prevent the luminance of the illumination means from being lowered.

  Since the raised cloth 27 is disposed as a cushioning material on the outer bottom surface of the lower cover 24 located below the illumination means, it is possible to reduce the impact on the illumination means when the separation suction tool 9 performs cleaning. The reliability of the illumination means can be improved.

  The separation suction tool 9 can be easily separated from the suction tool main body 10, and can be cleaned while illuminating a narrow and dark place by the illumination means by the separation suction tool 9 in a separated state, and can be easily cleaned. .

  In the present embodiment, the illumination means is formed so as to face the lower surface intake port 13, but light can be emitted toward the front of the separation suction tool 9, and illumination is performed with the separation suction tool 9 attached to the suction tool body 10. Any other position may be used as long as the means is a position covered by the suction tool main body 10.

  As described above, since the vacuum cleaner according to the present invention can be cleaned conveniently while illuminating a dark place such as a gap, it can be applied not only for home use but also for business use vacuum cleaners and the like.
