2. Description of the Related Art A cyclone dust collecting type electric vacuum cleaner comprises an electric vacuum cleaner body having an electric blower built therein and a dust collecting container detachably mounted on the vacuum cleaner body. Has an intake port and an upper opening, and the filter body is detachably attached to the upper opening.

In the case of this electric vacuum cleaner, the air sucked from the suction port body (not shown) by the drive of the electric blower is sucked into the dust container through the suction port. The sucked air flows spirally along the inner peripheral surface of the dust collecting container,
After that, the air is sucked into the electric blower through the filter at the upper opening of the dust collecting container.

On the other hand, the dust sucked together with the air from the suction port body falls downward by its own weight and accumulates at the bottom of the dust collecting container as it flows with the vortex of the air in the dust collecting container.

In this type of vacuum cleaner, it is desirable that as much dust as possible be stored in the limited space of the dust container.

Conventionally, there has been known an electric vacuum cleaner provided with a mechanism for collecting a large amount of dust. The mechanism is provided with a press plate movable up and down in the dust collecting container, and the press plate is lowered by operating a button. When a predetermined amount of dust is collected in the dust container, the button is operated to lower the press plate. The dust is compressed as the press plate descends, so that more dust can be stored.

[0007]

However, in the conventional mechanism, there is a problem in that the button has to be manually operated to lower the press plate, which is a troublesome operation. The present invention has been made in view of the problems of the technology, and an object thereof is to provide an electric vacuum cleaner that can increase the amount of accumulated dust without requiring manual operation.

[0008]

The electric blower 2 sucks the air in the dust container 10 through the guide air passage 36 of the lid (see FIG. 3).

The air taken into the electric blower 2 is exhausted from the exhaust port 13 of the main body 3.

The lid 6 has a dust collecting container 10 which will be described later.
Is joined to the intake port 12 of the. A joint opening (not shown) was formed, and the joint opening and the connection port 7 communicated with each other.

As shown in FIG. 4, the dust collecting container 10 is vertically separable from a cyclone case 14 and a dust collecting case 15, and the cyclone case 14 is placed on the dust collecting case 15.
Is detachably joined.

An intake port 1 is provided on the side of the cyclone case 14.
2 is formed, and a cylindrical portion 17 hangs on the top plate wall 14A of the cyclone case 14. A small-diameter cylindrical portion 14B is formed in the cylindrical portion 17, and an upper opening 19 is formed on the cylindrical portion 14. A filter F6 is attached to the lower portion of the tubular portion 14. A space between the cylindrical portion 17 and the outer peripheral wall 14G of the cyclone case 14 serves as a ventilation path 18 that guides the air sucked from the intake port 12 to the dust collection case 15 as a vortex.

The eddy current descends along the peripheral wall of the dust collection case 15. After this, the air rises in the central portion of the dust collection case 15, passes through the tubular portion 14B in the tubular portion 17, and the upper opening 19
Is sucked into the electric transmitter 2.
The air taken into the electric blower 2 is exhausted from the exhaust hole 13 of the main body 3.

A press plate 20 is provided in the dust collection case 15 so as to be movable up and down. As shown in FIGS. 5 and 6, the press plate 20 includes a donut-shaped disc 21 having a radial cut. , And a cylindrical knob 24 attached to the central portion of the disk 21.

One end of the disk 21 is bent upward from the position shown by the broken line A to form an opening 23 facing the flow of the vortex. One end of the disc 21 is an upper edge 23a of the opening 23, and the other end of the disc 21 is a lower edge 23b of the opening 23. Further, a pair of recesses 25 are formed on the outer peripheral edge of the disc 21 at positions facing each other, and a protrusion 26 is formed on the lower surface of the disc 21.

On the inner peripheral wall of the dust collecting case 15, a pair of guide rails 28 extend vertically and are located at opposite positions.
Is formed, and the guide rail 28 is formed by the press plate 2.

It enters into the lower part of the disc 21 through the opening 23. Since the protrusion 26 is formed on the lower surface of the disk 21,
Since there is a gap between the circular plate 21 and the bottom wall 15A of the dust collection case 15, the dust easily enters from the opening 23 to the lower side of the circular disc 21 even at the initial stage when the dust is not accumulated. .

Since the dust is pushed into the lower part of the disc 21 through the opening 23, the dust D of a predetermined amount or more is produced.
When the dust is accumulated, the pressing plate 20 is raised by the pressure of the pushing, and the dust D is accumulated under the disc 21.

The dust D accumulated under the circular plate 21 is pressed by the weight of the press plate 20 and thus accumulated in a compressed state. Therefore, a large amount of dust D can be accumulated in the dust collection case 15.

As described above, since the dust D is compressed and accumulated under the disc 21 of the press plate 20, the manual operation for compressing the dust D becomes unnecessary. [Second Embodiment] FIG. 8 shows a press plate 30 according to a second embodiment.
