Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner, which can effectively compress dust collected in a dust collection case and dispose of the compressed dust extremely easily and hygienically. The purpose is to scale.

In this invention, a dust collection case is provided with a lid and a compression plate that face each other vertically, and an opening/closing operation plate that opens and closes the lid.When compressing dust, the lid is closed and the compression plate facing the lid is operated independently. Therefore, the dust can be compressed with sufficient pressure so that the dust does not fly up when disposing of the dust, and when disposing of the dust, the opening/closing operation plate is lowered to open the lid, but at this time the opening/closing operation plate is lowered. The compression plate is lowered in conjunction with the movement, so the lid is opened in one motion and the dust is pushed out by the compression plate, making it possible to dispose of the dust hygienically and extremely easily without having to pick it up by hand. It is something.

An embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes an electric case that houses and holds an electric blower 2, and a dust collection case 4 is detachably attached to one end of the electric blower 1 with a clamp 3.

The dust collecting case 4 has a trapezoidal shape with both side walls 5 and one end wall 6 expanding downwardly, and the one end wall 6 has a suction port 7 formed therein.

Further, an end frame 9 having a suction port 8 is attached to one end of the dust collection case 4.

A filter unit 10 is housed and held on the electric case 1 side of the dust collection case 4, and a compression plate 11 is provided on the upper part so as to be vertically movable.

This compression plate 11 is fixed to the lower end of the operating piece 13 which is urged upward by a spring 12.

Further, lids 15 and 16 for opening and closing the opening 14 are rotatably attached to the lower part of the dust collecting case 4 on both sides.

A steering wheel 17 is attached to one lid 16.

Next, an opening/closing operation plate 18 for pushing open the lids 15 and 16 is inserted between the dust collection case 4 and the end frame 9 so as to be vertically movable.

That is, the lids 15 and 16 are each suspended from the opening/closing operation plate 18 by wires 19.

This opening/closing operation plate 18 has a vertically long escape opening 20 formed in the center thereof facing the suction ports 7 and 8, and has a pressurizing member attached to the upper surface of a projection piece 21 which serves as a pressure receiving part of the operation piece 13 at the upper part. A protruding piece 22 which is a pressure part is formed.

In such a configuration, the spring 12 urges the compression plate 11, the operation piece 13, and the opening/closing operation plate 18 upward, so that the lids 15, 16 are suspended from the opening/closing operation plate 18 via the wire 19. The opening 14 is closed.

Then, cleaning is performed by connecting suction hoses (not shown) to the suction ports 7 and 8 and driving the electric blower 2.
The dust 23 is collected in sequence on the bottom of the dust collection case 4, that is, on the lid 15, 16.

Then, by removing the suction hose and pushing the operating piece 13, the compression plate 11 is lowered to compress the dust 23.

At this time, the opening/closing operation plate 18 released by the spring 12 is temporarily in a free state, but since the lids 15 and 16 are supported on the floor via the steering wheel 17, the opening/closing operation plate 18 cannot be lowered by its own weight. There isn't.

This is due to the reason that the operating piece 13 is operated independently.

When the user releases the operation piece 13, the compression plate 11 returns, but since the dust 23 is compressed from top to bottom, the compression plate 11
It remains stable without collapsing even if it is evacuated.

Then, remove the dust collection case 4 from the electric case 1 and pull the handle 4.
Grasp the dust 23 and carry it to a place where it should be thrown away, and then remove the lid 15,
When opening 16, the dust 23 is thrown away.

At this time, since the opening 14 is formed directly below, there is no need to change the direction of the dust collecting case 4, and the dust 23 is released in the compressed direction, so that there is less dust flying up, which is sanitary.

If the compression plate 11 is pushed down in this state, there is no need to pick up the dust, making it even more sanitary and allowing the dust 23 to be thrown away very easily.

Further, when the opening/closing operation plate 18 is pushed down, the compression plate 11 is pushed down and the lids 15 and 16 are opened, so that the work of discarding the dust 23 can be performed even more easily.

Furthermore, since the dust collection case 4 expands downward, the resistance to push out dust is also small.

Even in this case, when the user releases the opening/closing operation plate 18, the opening/closing operation plate 18 and the compression plate 11 are returned to their original positions by the force of the spring 12, and the lids 15, 16 are also pulled by the wire 19 and closed.

Since this invention is configured as described above, the compression plate facing the lid can be lowered independently with the lid closed, and thereby dust can be firmly compressed by the lid and the compression plate. In addition, the lid can be opened in one motion by simply pressing the opening/closing operation plate, and the dust can be pushed out by the compression plate. Therefore, dust can be disposed of hygienically and extremely easily without having to pick up dust. It has the following effects:

Claims (1)

[Claims] 1. A lid for opening and closing the opening for disposing of dust is attached to the bottom surface of the dust collection case connected to an electric case having an electric blower so as to be movable up and down, and a compression plate facing the lid is attached to the top of the dust collection case. an operating piece having a pressure receiving part on the compression plate is provided to protrude outside from the dust collection case so that the compression plate can be moved up and down independently, and the pressure receiving part of the operation piece of the compression plate is provided on the dust collection case. 1. An electric vacuum cleaner characterized in that an opening/closing operation plate having a pressurizing part that applies pressure downward is attached so as to be movable up and down, and the opening/closing operation plate and the lid are interlocked and connected.
