Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

Conventionally, there is a type of dust collection case in which one side of a lid is rotatably connected to an opening formed on the lower surface of the dust collection case, and dust is disposed of by opening the lid.

As a result, the dust does not slide on the sloping lid and fall directly below the dust collection case until the lid is completely opened.

On the other hand, when disposing of dust, the dust collection case is placed along the side of the human body, which is a natural posture that requires less effort and does not require the user to extend their hands forward.

Depending on whether you are hanging the dust collection case with your right or left hand, the direction in which the lid opens and closes, as well as the direction in which the lid is tilted during the opening and closing process, changes.In many cases, the direction of the lid is directed toward the human body, and therefore, falling dust can land on your pants and feet. It has the disadvantage of staining.

The object of the present invention is to provide a vacuum cleaner that can avoid the above-mentioned drawbacks.

In this invention, a dust collection case having a handle at the top and an opening for disposing of dust at the bottom is connected to an electric case, and a pair of lids are installed on both sides of the opening of the dust collection case. is rotatably attached with an axis in the longitudinal direction of the handle, and the upper end of the opening/closing operation body that operates together with a compression plate that compresses dust downward by a suppressing action to open the lid is brought close to the handle. The opening/closing operation body is biased upward.

In other words, by opening the lid on both sides, dust can fall directly below the opening formed on the bottom of the dust collection case, and even if you hold the dust collection case with either hand, the lid will open on either side. Acts as a barrier to the human body, thereby
Prevents dust from adhering to the human body when disposing of dust, and
Since the opening is formed on the bottom of the dust collection case, the dust collection case can be easily disposed of without having to change the dust collection case.

An embodiment of this 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 is formed with a suction lower.

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.

A pair of lids 15 and 16 for opening and closing the opening 14 are rotatably attached to the bottom of the dust collecting case 4 on both sides.

A steering wheel 17 is attached to one lid 16.

Next, between the dust collection case 4 and the end frame 9, there is an opening/closing operation plate 1 that serves as an opening/closing operation body for pushing open the lid 15.16.
8 is inserted so that it can move up and down.

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 lower 8, and a protrusion 22 that joins to the upper surface of the protrusion 21 of the operation piece 13 at the upper part. ing.

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, a suction hose (not shown) is connected to the suction lower 6 and the electric blower 2 is driven.As a result, cleaning is performed, and the dust 23 is removed from the bottom surface of the dust collection case 4, that is, the lid 15.16.
are placed on top of each other in sequence.

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 becomes temporarily free, but since the lids 15 and 16 are supported on the floor via the steering wheel 17, the opening/closing operation plate 18 lowers due to its own weight. Never.

This is because the operation piece 13 can be 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.
When the lids 15 and 16 are opened on both sides and the compression plate 11 is also pushed down by the opening/closing operation plate 18, the dust 23 is removed from the opening 14. being pushed out.

At this time, since the lids 15 and 16 are opened on both sides, the dust 23
falls directly below the opening 14.

Furthermore, as shown in FIG. 4, even if the pusher 4a is hung by either the right or left hand, either the lids 15, 16 will always act as a shield against the human body A.

Therefore, even if the dust collection case 4 is located above the opening surface of the trash can 24, the dust 23 will not adhere to the human body A, which is sanitary.

Further, since the opening 14 is formed on the bottom surface of the dust collection case 4, dust can be easily disposed of without changing the direction of the dust collection case 4.

Even when the dust 23 is compressed by the compression plate 11, it expands as the one end wall 6 and side wall 5 of the dust collection case 4 move downward, and the dust 23 can be pushed out by the compression plate 11, making dust disposal even more sanitary. It is also easily done.

As described above, this invention has a pair of lids rotatably attached to both sides of the opening formed on the bottom of the dust collection case, so that dust can be disposed of directly under the dust collection case, and at this time, the dust can be disposed of directly under the dust collection case. The operating body can be easily operated with one hand while holding the handle, and as the lid is opened, the compression plate also moves to push out the dust inside, making it easy for dust to fall out and to the opening/closing operating body. When the pressing force is released, the lid is automatically closed, and one of the lids always acts as a barrier to the human body, thereby preventing dust from adhering to the human body. Furthermore, the dust collection case has the advantage that dust can be easily thrown away from the opening at the bottom without changing the direction of the dust collection case.
