In this state, the guide rib 69 abuts against the protrusion 59 to restrict the rotation of the lid body 19.

The storage battery 8 will be described based on FIG. The storage battery 8 includes a front case 61 and a rear case 62, and houses a secondary battery therein. The storage battery 8 has a handle 65 at the top, and the handle 65 is configured to be extendable and contractable by a handle arm 63. A storage battery terminal portion 64 that fits into the terminal frame 40 of the storage battery case body 17 is disposed below the storage battery 8, and a terminal (not shown) is supported on the storage battery terminal portion 64.

  Ribs 66 and 67 are formed on the side surface of the cleaner body 1 of the storage battery 8 in the front-rear direction. The ribs 66 and 67 are located on the inner side of the cleaner body 1 from the central axis in the left-right direction of the cleaner body 1 of the storage battery 8. It forms so that it may be located in.

  The charging stand 25 will be described based on FIG. The charging stand 25 stores a control board (not shown) to which the power cord 26 is connected, and has a terminal receiving portion 54, and the terminal receiving portion 54 has a storage battery case main body attached to the cleaner body 1. The 17 terminal part frame 40 and the storage battery terminal part 64 of the storage battery 8 are selectively connected.

  As shown in FIG. 4, a cord reel case 11 having a built-in cord reel 9 for supplying AC power to the electric blower 5 is attached to the left side of the vacuum cleaner main body 1 in the drawing.

  The cord reel case 11 will be described with reference to FIGS. 19 and 20. Reference numeral 20 denotes a cord reel case body, which is formed in a bottomed cylindrical shape having an opening at one end, and forms a communication port through which a part of the exhaust of the electric blower 5 passes on the side surface of the cleaner body 1 side. An annular support portion 21 is formed on the opening side of the cord reel case body 20, the axle portion 43 is fitted and supported on the outer periphery of the support portion 21, and the wheel portion 7 b is rotatable on the outer periphery of the groove portion 24 formed in the axle portion 43. It is supported by. A lid 22 is fixed to the cord reel case main body 20 with a screw so as to cover the opening, and the wheel portion 7b is prevented from being supported between the cord reel case main body 20 and the lid 22 and supported. The cord reel 9 is rotatably supported in a space surrounded by the case body 20 and the lid body 22. The axle portion 43 is made of a material having a low frictional resistance, such as polyacetal. Reference numeral 44 denotes an operation lever attached to the cord reel case body 20 for operating the winding of the cord reel 9.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below, adding FIGS. 15-18.

  FIG. 15 is a perspective view showing a state where the cleaner body is placed on the charging stand. FIG. 16 is a cross-sectional view for explaining a mounting state of the battery case. FIG. 17 is a perspective view showing a state in which a storage battery is attached to and detached from the battery case. FIG. 18 is a perspective view showing a state where the storage battery is attached to the charging stand.

  When the user starts cleaning using the electric vacuum cleaner 100, power is supplied from the storage battery 8 to the electric blower 5, and suction air is generated by the electric blower 5. When suction wind is generated by the electric blower 5, dust on the surface to be cleaned is sucked together with air from the suction tool 2. The air containing the dust sucked from the suction tool 2 flows into the cleaner body 1 through the extension pipe 3 and the hose 4, and only the dust is collected by the dust collector 6.

  When the user connects the cord reel 9 to a commercial power source and starts cleaning using the electric vacuum cleaner 100, power is supplied from the commercial power source to the electric blower 5, and suction air is generated by the electric blower 5. . When suction wind is generated by the electric blower 5, dust on the surface to be cleaned is sucked together with air from the suction tool 2. The air containing the dust sucked from the suction tool 2 flows into the cleaner body 1 through the extension pipe 3 and the hose 4, and only the dust is collected by the dust collector 6.

As shown in FIG. 16, when the user finishes cleaning and charges the storage battery 8, the user connects the power cord 26 to a commercial power source, places the cleaner body 1 on the charging stand 25, and The storage battery 8 is charged.

  Further, as shown in FIGS. 16 and 17, when the user finishes cleaning and charges the storage battery 8 alone, the user operates the buckle 42 to move the lid 19 to the outside of the cleaner body 1. To open the lid 19, take out the storage battery 8, place it on the charging base 25, and charge the storage battery 8.

  As described above, in the present embodiment, the storage battery 8 is housed in the storage battery case 10 of the cleaner body 1 and covered with the lid body 19, so that when the user uses the electric vacuum cleaner 100, the storage battery 8 rises. Since the dust does not enter the connecting portion between the cleaner body 1 and the storage battery 8, it is possible to suppress poor contact between the cleaner body 1 and the storage battery 8.

  Further, in the present embodiment, when the storage battery 8 is mounted on the cleaner body 1, the storage battery 8 is fitted by the holding rib 68 between the terminal frame 40 of the storage battery case 10 and the storage battery terminal 64 of the storage battery 8. The terminal part frame body 40 and the storage battery terminal part 64 can be reliably fitted by the weight of the storage battery 8 guided to the position.

  Since the storage battery 8 can be removed from the vacuum cleaner body 1 and charged, it can be handled more easily than when the entire vacuum cleaner is carried and charged, and the charging operation of the user is facilitated. Can do. Moreover, since the small and lightweight storage battery 8 is charged compared with the whole vacuum cleaner, the charging stand 25 can be reduced in size and the storage space of a vacuum cleaner can be decreased.

  When the cleaner body 1 is placed on the charging stand 25, the wheels 7a and 7b of the cleaner body 1 are charged in a grounded state, so that the stability of the charged cleaner body 1 is maintained. Thus, charging can be performed without increasing the installation area of the charging stand 25.

  Further, in the present embodiment, when the user attaches the storage battery 8 to the cleaner body 1, the storage battery 8 may be attached to the storage battery 8 even if the user tries to attach the storage battery 8 in the direction opposite to the left-right direction of the cleaner body 1. It is possible to easily determine that the provided ribs 66 and 67 interfere with the holding rib 68 of the lid 19 and cannot be mounted, and the usability of the vacuum cleaner 100 can be improved.

  Since the vacuum cleaner of the present invention can be charged by removing the storage battery and placing it on the charging stand, the charging stand can be miniaturized, so the field of household vacuum cleaners and industrial vacuum cleaners -It can apply suitably for a use.
