Further, at the rear portion of the suction portion 14, a projection 50 is formed which abuts on the pipe 39 in the carrying position and regulates downward swing of the tip of the suction portion 14.

In the above structure, the dust bag 3 is attached to the dust chamber 2 after first attaching the dust bag 3 to the mounting plate 4. To attach the dust collecting bag 3 to the mounting plate 4, the edge plate 3a of the dust collecting bag 3 is attached.
One end of the plate is brought into contact with the locking piece 20, and then the edge plate 3a is slightly curved by utilizing its elasticity, or the claw 18 of the mounting plate 4 is pushed by tilting the claw 18 by pressing it. Then, the other end of the edge plate 3a of the dust collecting bag 3 is inserted into the claw 18, and the dust collecting bag 3 is fixed by the claw 18 and the locking piece 20.

Next, the mounting plate 4 is inserted into the dust collecting chamber 2 from the inlet / outlet 7 so that the surface on which the dust collecting bag 3 is mounted is located inside the dust collecting chamber 2. Then, after fitting one end of the edge plate 3a of the dust collecting bag 3 into the engaging piece 26 of the intake panel 24, the end of the mounting plate 4 on the inlet / outlet 7 side is pushed toward the intake port side. Then, the mounting plate 4 rides over the elastic engagement claw 29 of the clamp piece 6 and is sandwiched between the mounting plate 4 and the contact portion 28, and is mounted on the intake panel 24. At this time, the urging force of the spring 30 is so small that the clamp piece 6 is swung to the free posture B side, and the rear end of the edge plate 3a of the dust bag 3 is the engagement piece 26 of the intake panel 24. And the mounting plate 4
Since the rear surface of the rear end of the clamp piece 6 is in close contact with the intake panel 24, the clamp piece 6 maintains the clamp posture A regardless of the biasing force of the spring 30.

The intake panel 24 has a guide piece 24 as shown by a chain line in FIG.
By forming a, it is possible to prevent the mounting plate 4 from rotating and the clamp piece 6 to be in the free posture B even when the biasing force of the spring 30 is large.

After the dust collecting bag 3 is attached, the protruding piece of the case cover 8
36 is inserted into the lower concave portion 37b of the electric vacuum cleaner body 1, and the case cover 8 is rotated about this, and the engaging piece 32 of the engaging portion 31 is pushed down to cover the case cover 8 on the doorway 7. After that, when the hand is released, the engaging piece 32 projects from the case cover 8 by the spring 33 and is fitted into the upper recess 37a.

At this time, since the clamp piece 6 is in the clamp posture A,
The projecting piece 12 of the case cover 8 does not come into contact with the cover mounting prevention piece 11 of the clamp piece 6, and the case cover 8 can be mounted.

Here, if the dust bag 3 is not attached to the mounting plate 4 but only the dust bag 3 is attached to the dust chamber 2, the clamp plate 6 remains in the free posture B because the mounting plate 4 is not provided. Even if the case cover 8 is mounted, the projecting piece 12 comes into contact with the cover mounting prevention piece 11 of the clamp piece 6, and the case cover 8 cannot be mounted. This makes it possible to recognize that the mounting plate 4 has been forgotten.

Further, when only the mounting plate 4 is mounted in the dust collecting chamber 2 without mounting the dust collecting bag 3 on the mounting plate 4, the mounting plate 4 is not supported by any part of the back end of the mounting plate 4, so that the mounting plate 4 is not supported. When it is pushed along 24, the rear end notch 21 enters the engaging piece 26 and is housed in the dust collecting chamber 2 in a state where it is not engaged with the engaging claw 29. Therefore, the clamp piece 6 is in the free posture B, and even when the case cover 8 is attached, the protrusion piece 12 hits the prevention piece 11 and cannot be attached. As a result, the fact that the dust bag 3 has been forgotten is recognized.

Therefore, even if you forget to attach the dust bag 3 or the mounting plate 4,
Since the case cover 8 cannot be attached to the electric vacuum cleaner body 1, it is possible to prevent forgetting to attach the dust collecting bag 3 or the mounting plate 4, and the electric vacuum cleaner is not used as it is. Therefore, it is not necessary to provide a separate part such as a filter paper box, and the number of parts can be reduced.

When the vacuum cleaner body 1 of this example is placed upright, the suction portion 14 is tiltable with respect to the vacuum cleaner body 1,
The vacuum cleaner body 1 becomes unstable, and a fall prevention mechanism for the vacuum cleaner body 1 is required. Also, without this mechanism,
When the electric vacuum cleaner body 1 is carried, the suction portion 14 freely swings, which may damage the floor surface.

However, in this example, since the pipe 39 is provided, it can be prevented from falling and can be easily carried. That is, when the electric vacuum cleaner body 1 is placed upright, the pipe 39 is switched to the carrying posture. To switch the pipe 39 from the use position to the carry position, push the push piece 43, retract the fixing pin 47 from the pipe guide 41 by the pusher 45, and then push down the pipe 39 to contact the floor surface. Let it be in a carrying position. In this carrying posture, the other fixing pin 47 of the pipe 39 projects from the lateral hole 44 of the pipe guide 41, and the pipe 39 is fixed at this position.

At this time, the pipe 39 is placed on the floor, and the main body 1 can be stood upright in a stable state.

Also, when carrying the vacuum cleaner body 1, the pipe 39
Is brought into contact with the protrusion 50 of the suction portion 14, so at least swinging of the suction portion 14 below the tip can be prevented, and the movement is facilitated. Moreover, it is not necessary to provide the suction portion 14 with another component that performs these functions.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the spring of the clamp piece 6 is not limited to the coil spring,
The clamp itself may be an elastic body.

<Effect of the Invention> As is clear from the above description, according to the present invention, the vacuum cleaner can be housed in the dust collection chamber of the main body, and one side of the dust bag is attached and a notch is formed on the other side. By engaging the plate with the other side of the dust collecting bag through the notch of the mounting plate, the other end of the mounting plate is engaged with the chamber wall of the dust collecting chamber and the other side of the mounting plate. Side engaging part prevents engagement of the other side of the mounting plate by itself, and the engaging part engages the other side of the dust collecting bag through the notch of the mounting plate. A clamp piece arranged on the chamber wall of the dust collecting chamber, where one end of the mounting plate is mounted and clamped on the chamber wall of the dust collecting chamber; and a case cover for opening and closing the dust collecting bag inlet and outlet of the dust collecting chamber. The clamp piece has a clamp posture when the dust bag and the mounting plate are attached to the chamber wall of the dust collection chamber, and a free posture when the dust bag and the mounting plate are not attached. And a dust collection bag non-attachment preventing means for preventing the case cover from closing when the dust collection bag and the mounting plate are not attached to the dust collection chamber. The non-attachment prevention means includes a cover attachment prevention piece formed on the inlet / outlet side of the clamp piece, and a cover attachment prevention piece formed on the inner wall of the case cover in contact with the cover attachment prevention piece in a free posture of the case cover to the doorway of the case cover. It is made up of a projection to make it impossible to attach it.If you forget to attach the dust collecting bag and the mounting plate, you cannot attach the case cover to the vacuum cleaner body, so attach the dust collecting bag and the mounting plate. It has an excellent effect that it can surely prevent forgetting.
