This Patent Document 1 is provided with a holder that is attached to a connection pipe, a winding attachment portion that is attached to the holder by being wound around the connection pipe, and an attachment mounting cylinder that is attached to the attachment. And the narrow mouth suction opening is mounted | worn with the attachment mounting cylinder.

Japanese Patent Laid-Open No. 3-128022

  However, in the above-mentioned Patent Document 1, since the holder is only attached by being wound around the connection pipe, when the connection pipe is moved for cleaning, the holder collides with an obstacle and falls. Rotated and loosened and dropped.

  The objective of this invention is providing the vacuum cleaner which suppressed the fall of the said subject and suppressed the fixture which attaches the accessory for cleaning.

In order to achieve the above object, the present invention is characterized by a vacuum cleaner body having an electric blower and a dust collecting part, a hose connected to the vacuum cleaner body, and a hand operating part connected to the hose. And a vacuum cleaner provided with an extension pipe connected to the hand operation section, and a floor suction tool connected to the extension pipe,
The extension pipe includes a hook body that protrudes to the outside,
A holding tool for attaching a cleaning accessory to the extension pipe is provided, and the holding tool is engaged with the hook body.

  ADVANTAGE OF THE INVENTION According to this invention, the vacuum cleaner which suppressed the fall of the holder which attaches the cleaning accessory can be provided.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 9 is an external perspective view of a vacuum cleaner 100 according to one embodiment of the present invention. In FIG. 9, reference numeral 110 denotes a vacuum cleaner body having a dust collection unit and an electric blower built therein, and 120 denotes a hose having one end connected to the vacuum cleaner body 110 via a hose joint 120a. Reference numeral 130 denotes a hand operating part having one end connected to the other end of the hose 120. The hand operating part 130 is provided with a handle part 130a gripped by the user and a switch means 130b for controlling the electric blower. Reference numeral 140 denotes an extendable extension tube having one end connected to the other end of the hand operation unit 130 and composed of two tubes. A floor suction tool 150 is connected to the other end of the extension pipe 140.

  In such a configuration, when the switch unit 130b disposed in the hand operation unit 130 is pressed, the electric blower built in the cleaner body 110 is operated to generate a suction force. Due to this suction force, dust is sucked together with wind from the floor suction tool 150, and the dust is collected in the vacuum cleaner main body 110 through the ventilation path formed by the extension pipe 140, the hand operating section 130, and the hose 120. Collect dust.

  The vacuum cleaner 100 is attached with a suction tool other than the floor suction tool 150 so that various places can be cleaned. For example, in this embodiment, the brush suction tool 160 is connected between the extension pipe 140 and the floor suction tool 150. When the connection between the brush suction tool 160 and the floor suction tool 150 is released, the brush 160a protrudes from the front of the brush suction tool 160, and the top of the shelf can be cleaned. In addition to the brush suction tool 160, a suction tool for a gap is also attached. The present embodiment relates to a structure for attaching a suction tool for a gap, and the configuration will be described with reference to FIGS.

  FIG. 1 is an external perspective view showing a state where a suction tool 200 for a gap is attached to an extension pipe 140 according to an embodiment of the present invention, and FIG. 2 shows a configuration of a hook body 141 provided on the extension pipe 140. It is an external perspective view. FIG. 3 is an external perspective view of a holder according to an embodiment of the present invention, and FIG. 4 is an external perspective view showing a state in which the holder 300 is engaged with the hook body 141 of the extension tube 140. 5 is a cross-sectional view taken along the line AA in FIG. 4, and FIG. 6 is an enlarged view of a portion P in FIG. 7 is an external perspective view showing a state in which the suction tool 200 for gap is attached at a position different from that in FIG. 1, and FIG. 8 is an external perspective view showing a state in which the holder 300 is engaged with the hook body 141 of the extension pipe 140. FIG.

  In FIG. 1, the extension tube 140 includes an outer tube 140 a and an inner tube 140 b slidably provided in the outer tube 140 a, and can be expanded and contracted by operating a slide knob 142. The suction tool 200 for the gap is fixed to the extension pipe 140 by the holding tool 300. The suction tool 200 for the gap is composed of an outer tube 210 and an inner tube 220 slidably provided in the outer tube 210, and can be expanded and contracted by operating the operation unit 230.

  As shown in FIG. 2, hook bodies 141 are provided on the left and right of the outer tube 210 of the extension tube 140. The hook body 141 is provided with a protruding portion 142 extending from the extension tube 140 and an extending portion 143 extending from the protruding portion 142 along the longitudinal direction of the outer tube 141. The extending portion 143 is provided on the left and right sides of the protruding portion 142. The holder 300 is attached by engaging with the extending portion 143 of the hook body 141.

  The configuration of the holder 300 will be described with reference to FIG. The holder 300 is provided with an attachment part 310 attached to the outer periphery of the extension tube 140 and a holding part 320 for holding the suction tool 200. The attachment portion 310 is formed with a notch 311 into which the extended portion 143 of the hook body 141 is inserted.

  A method of attaching the holder 300 to the extension pipe 140 will be described with reference to FIGS. In FIG. 4, first, the holder 300 is attached to the extension tube 140 from the opening 312 of the holder 300. At this time, the holder 300 is attached to the extension tube 140 so that the hook body 141 and the notch 311 of the holder 300 face each other. Next, the holder 300 is slid toward the hook body 141, and the extending portion 143 of the hook body 141 is inserted into the cutout portion 311 of the holder 300. In this state, the extending portion 143 of the hook body 141 is inserted into the cutout portion 311 of the holder 300 as shown in FIG. FIG. 6 is an enlarged view of a portion P in FIG. A rib 144 is formed on the side of the extension portion 143 facing the extension tube 140, and the rib 144 is inserted into the notch portion 311 of the holder 300. Thereby, since the circumferential direction movement of the holder 300 is controlled, the fall of the holder can be suppressed.

  Next, another example of how to attach the holder 300 to the extension pipe 140 will be described with reference to FIGS. 7 and 8. In FIG. 1, the holder 300 is disposed on the right side of the extension tube 140. An example of mounting this on the left side will be described. In FIG. 8, first, the holder 300 is attached to the extension tube 140 from the opening 312 of the holder 300. At this time, the attachment portion 320 is positioned on the left side of the extension tube 140, and the hook body 141 and the cutout portion 311 of the holder 300 face each other. In order to make the hook body 141 and the notch 311 of the holder 300 face each other, the holder 300 is positioned closer to the hand operating section 130 than the hook body 141. That is, in FIG. 4, the holding tool 300 is positioned on the floor suction tool 150 side from the hook body 141, and the two are in an opposite relationship. In FIG. 8, the holder 300 is slid toward the hook body 141, and the extending portion 143 of the hook body 141 is inserted into the notch 311 of the holder 300.

  Then, as shown in FIG. 7, the attachment portion 320 of the holder 300 is positioned on the left side of the extension pipe 140, and the suction tool 200 is attached to the left side of the extension pipe 140.

  As described above, according to the present invention, it is possible to provide a vacuum cleaner that suppresses the falling of the holder to which the cleaning accessory is attached.
