FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1.

  In FIG. 1, the vacuum cleaner 40 in this Embodiment is the vacuum cleaner main body 1 which incorporates the electric blower 5 (refer FIG. 2) which generate | occur | produces a suction wind, The suction tool 2 which attracts the dust of a to-be-cleaned surface, The extension pipe 3 is connected to the suction tool 2 at one end, and the hose 4 is connected to the other end of the extension pipe 3 at one end and connected to the cleaner body 1 at the other end.

  The suction tool 2 has a built-in rotating brush (not shown) that scrapes dust on the surface to be cleaned and an electric motor (not shown) that rotates the rotating brush. Further, a tip pipe 7 having a handle portion 6 that is held when the user cleans is provided at the end portion of the hose 4 on the side of the extension tube 3. The hose 4 is detachably connected. Further, a connection pipe 8 is provided at the end of the hose 4 on the cleaner body 1 side, and the inlet 9 and the hose 4 of the cleaner body 1 are detachably connected via the connection pipe 8. ing. In the present embodiment, the intake port 9 is provided in an intake frame 17 described later.

  In addition, as shown in FIG. 1, the rear surface of the cleaner body 1 can be grounded to the floor surface, and the suction tool 2, the extension pipe 3, and the hose 4 can be stored in a state of being connected to the cleaner body 1.

  As shown in FIGS. 2 and 3, the vacuum cleaner body 1 includes a lower frame 12 having a dust collection chamber 10 formed in the front and an electric blower 5 and a cord winding device 11 in the rear, and the vacuum cleaner main body 1. The lower frame body 12 and the upper frame body 13 are coupled by screws (not shown) or the like.

  Further, a traveling caster 14 is attached to the front lower surface of the lower frame body 12 and wheels 15 are rotatably attached to both rear side surfaces. Further, a check valve 16 made of an elastic material is attached to the front end of the dust collection chamber 10, and an intake frame 17 is attached so as to cover the check valve 16. Further, an exhaust port 18 is formed at the rear portion of the cleaner body 1 for exhausting the exhaust discharged by the electric blower 5 after passing through the inside of the cord winding device 11.

  Moreover, the upper part of the dust collection chamber 10 is in an open state, and has a packing 19 around the entire upper end of the open part. The dust bag 20 is detachably mounted while facing the air inlet 9 of the dust chamber 10.

  A lid body 21 rotatably provided on the vacuum cleaner main body 1 with the rear portion serving as a fulcrum covers the upper opening 10 a of the dust collection chamber 10. When the lid body 21 is in a closed state and has a plane substantially the same shape as the packing 19 and the lid body 21 is in a closed state, the lid body 21 can be brought into pressure contact with the packing 19 to perform air tight.

  A plurality of legs 12 a, legs 13 a, and legs 13 b are provided behind the lower frame body 12 and the upper frame body 13 for storing the cleaner body 1 in an inverted manner on the floor surface.

As shown in FIGS. 4 and 5, a substantially concave engaged portion 22 is provided below the intake frame 17. Further, the intake frame 17 is formed with an inclination that is inclined downward from the outer periphery of the intake port 9 toward the inlet 22a of the engaged portion 22 with the rear surface of the cleaner body 1 placed on the floor surface. The walls 23 are provided symmetrically. In the present embodiment, the inclined wall 23 is provided approximately half a circumference.
The tip 23 a of the inclined wall 23 is formed so as to be connected to the inlet 22 a of the engaged portion 22.

  The extension tube 3 has a substantially L-shaped engagement portion 25 fixed to the outer surface of the tube portion 24 so as to fit into the substantially concave engaged portion 22 of the intake frame 17. A hooking portion 26 is provided at the front end and an inclined surface 27 is provided at the base.

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

As shown in FIGS. 6 and 7, the inclined surface 27 of the engaging portion 25 provided in the extension pipe 3 is formed on the inclined wall 23 of the intake frame 17 with the rear surface of the cleaner body 1 grounded to the floor surface. When the user releases the hand while making contact with the tip 23a, the extension tube 3 starts to slide down along the inclined surface 27 by its own weight.

  Next, when the hooking portion 26 of the engaging portion 25 slides down along the tip 23a of the inclined wall 23 while being hooked on the tip 23a of the inclined wall 23, and reaches the inlet 22a of the engaged portion 22, The hook portion 26 and the substantially concave engaged portion 22 are in the mounted state.

  That is, it is not necessary for the user to attach the engaging portion 25 of the extension pipe 3 to the engaged portion 22 of the intake frame body 17, and it is formed over a wide range with respect to the engaged portion 22 of the intake frame body 17. The mounting from either of the left and right inclined walls 23 is possible.

  Furthermore, it can be configured within the outer range of the intake frame 17 and can be reduced in size without increasing the size of the cleaner body 1.

  It goes without saying that the same effect can be obtained even when the suction pipe 2 and the tip pipe 7 of the hose 4 are connected to the extension pipe 3.

  In the above-described embodiment, the substantially L-shaped engaging portion 25 is provided in the tube portion 24 of the extension tube 3, but the substantially L-shaped engaging portion 25 is provided in the tube portion (not shown) of the suction tool 2. It goes without saying that the same effect can be obtained even if it is provided.

  As described above, the vacuum cleaner according to the present invention can easily perform the work of housing the vacuum cleaner body by attaching the extension tube to the vacuum cleaner body, and is further small without increasing the size of the vacuum cleaner body. Therefore, it can be applied to various vacuum cleaners for home use and business use.
