And a hook body 61 for connecting the extension pipe 6 to the first pipe body 31 is held by a spring 55. In the present embodiment, the notification lamp 60 is an LED that is a light emitting element, and the light control unit 53 is a display substrate having a circuit.

  The light control unit 53 causes the notification lamp 60 to emit light, extinguish light, and blink according to the electrical signal supplied from the control unit 50 based on the presence or absence of dust sucked by the vacuum cleaner 1 or the amount of dust sucked. . Or it is also possible to express and display the amount of dust accumulated in the dust collection chamber (not shown) of the vacuum cleaner 1 or the abnormal state of operation.

  Further, in order to measure the presence or absence of dust or the amount of dust to be sucked, for example, a dust sensor (not shown) is provided inside the hose joint 10. Thereby, the presence or absence of dust or the amount of dust to be sucked is detected, and the notification lamp 60 is turned on, turned off, and blinked in conjunction with the dust sensor.

  As shown in FIG. 12, the light control unit 53 is held in the vertical direction by the ribs 26 provided in the first tubular body 31 and fixed by being sandwiched by the second cover body 41.

  In addition, a lens 54 is provided in the vicinity of the notification lamp 60 mounted on the light control unit 53, and the lens 54 is held by being sandwiched in the recess 42 of the second cover body 41.

  The light from the notification lamp 60 enters the lens end surface 62 of the lens 54 and is irradiated in the direction of the second grip portion 44.

Further, as shown in FIGS. 9 and 12, the lens 54 is disposed so that the top surface 63 of the lens 54 is parallel to and substantially flush with the top surface of the second cover body 41. Further, an inclined surface 64 is provided on the bottom surface side of the lens 54, and the inclined surface 64 is inclined from the front to the rear of the suction gripping part 5 so as to face upward. Due to this inclination, a screw 66 for fastening the first tube body 31, the first cover body 40, and the second cover body 41 is incorporated into the lower surface of the lens 54 using the provided space. Thereby, since the screw 66 is not exposed to the appearance, the appearance is improved.

  Also, as shown in FIGS. 8 and 11, between the vicinity of the bent portion of the first tubular body 31 and the first cover body 40, power is supplied from the power supply line of the hose member 20 to the control unit 50. A lead wire (not shown) is held. All the lead wires are held by being sandwiched between ribs (not shown) provided in the first tubular body 31.

  Next, the effect | action by the said structure is demonstrated below using FIG.

  When the notification lamp 60 emits light, light enters from the lens end surface 62 of the lens 54, travels through the lens 54, reflects the light hitting the outer peripheral surface of the lens 54, and is incident on the top surface 63 of the lens 54. Will come out and can be visually recognized by the user who is grasping and operating the suction gripping part 5 of the hose 3.

  The amount of dust sucked by the vacuum cleaner 1 is displayed according to the display state of the light control unit 53 (for example, lighting, extinguishing, and blinking). If there is no dust sucking, the cleaning operation is unnecessary. This makes it possible for the user to recognize this and to reduce the domestic labor.

  Further, an inclined surface 64 formed on the bottom surface of the lens 54 is arranged so as to face from the front to the rear of the suction gripping part 5 and to face upward, and further to the inclined surface 64 from the front to the rear of the suction gripping part 5 in a stepwise manner. By providing the concave and convex portion 54a with a deeper depth, diffusion of light at a location close to the light source is suppressed, and diffusion of light at a location far from the light source is increased.

  Thereby, since the light which goes out to the top | upper surface 63 of the lens 54 is uniform on the whole top | upper surface of the lens 54, the irradiation range is wide and it is excellent in visibility. A plurality of notched grooves (not shown) whose groove shape is gradually changed may be provided on the bottom surface of the lens instead of the unevenness 54a.

  Further, by sandwiching the reflecting plate 65 between the lens 54 and the second cover body 41, the light passing through the bottom surface of the lens 54 is reflected, the amount of light toward the top surface 63 is increased, and the visibility is improved. . In addition, since the light traveling toward the top surface 63 is dispersed by applying the embossing to the top surface 63 of the lens 54, it is possible to reduce irritation to the eyes by the light of the notification lamp 60 while ensuring visibility. I can do it. In addition, since the top surface 63 of the lens 54 and the top surface of the second cover body 41 are positioned in parallel, the external surface is flat and the external appearance is not impaired.

  The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.

  The vacuum cleaner according to the present invention can improve the visibility of the notification lamp, and can be applied to various vacuum cleaners for home use and business use.
