Description

[Detailed description of the invention] This invention relates to a vacuum cleaner in which a dust collection case and a main body case are connected in parallel.

Generally, this type of device has a dust collection case detachably attached to the main body case.

Then, an opening for disposing of dust is formed at the bottom of this dust collection case,
A lid body for opening and closing this opening is rotatably attached.

However, since there is a protruding locking piece etc. on the open end side of the lid that locks with the locking device of the dust collection case and maintains the lid in the closed state, it is difficult to open the lid to remove dust. Although the dust falls along the inner surface of the lid when discarded, the locking pieces protruding from the inner surface near the open end may prevent the dust from falling.
Dust gets caught and fine dust is thrown up, and furthermore, the caught dust must be disposed of by hand, making it difficult to dispose of dust easily and hygienically.

This idea was developed in consideration of these points, and the purpose is to provide a vacuum cleaner that can securely close the lid and dispose of dust easily and hygienically when disposing of dust. It is something.

This idea includes a dust collection case that is removably attached to the main case with a built-in electric blower and has a fixed locking part and a movable locking part, and an opening for disposing of dust at the bottom of the dust collection case. and a lid body having the fixed locking part at the open end and rotatably attached to open and close the opening, the inner surface of the lid body being formed smoothly toward the open end, A locking portion is formed on the end surface of the open end in a state that does not protrude from the inner surface while being located between the inner surface and the fixed locking portion, and the locking portion is located above the locking portion on the dust collection case. The present invention is characterized in that a locking device is provided that opens and closes the lid body by locking and disengaging the locking portion.

Therefore, the lid can be opened and closed reliably by engaging and disengaging the locking device with the locking part of the lid, and when disposing of dust, the locking part does not prevent the dust from falling, making it easy to remove dust. It is designed so that it can be processed hygienically.

An embodiment of this invention will be explained based on the drawings.

Reference numeral 1 denotes a main body case in which an electric blower 2 is built-in, and a dust collection case 4 equipped with a filter section 3 is detachably connected to the front end side of the main body case.

A suction port 5 is formed at the front end of the dust collection case 4, and an opening 6 for disposing of dust is formed at the bottom.

Further, a lid 7 for opening and closing the opening 6 is rotatably attached at its front end to a hinge 8 provided on the dust collection case 4.

This lid body 7 has walls 9 formed on both sides thereof, and an inner surface 10 is formed smoothly from the front end toward the open end 11, and is shaped like a gutter.

A locking protrusion 12, which is a fixed locking portion, is formed protruding from the lower edge of the open end 11 of the lid body 7, located approximately in the center.

On the other hand, a clamp 13 is provided at the upper rear end of the dust collecting case 4, which is a movable locking portion that is biased upward and is slidable.

Further, on the front end side of the main body case 1, a retaining hole 14 into which the clamp 13 and the locking protrusion 12 are engaged and disengaged, and an engagement recess 15 are formed.

A locking portion 16 is formed at the open end 11 of the lid 7 so as to be located between the inner surface 10 and the locking protrusion 12 .

That is, this locking part 16 is formed in the groove 1 which is formed slightly wide.
7 with a predetermined interval left in a protruding manner.

Further, a guide groove 18 is formed adjacent to the groove 17 in the open end 11 and has a slightly tapered upper part.

Further, a clamp 20, which is a locking device that locks and disengages from the locking portion 16, is attached to the lower part of the rear end wall 19 of the filter section 3.

That is, the clamp 20 is always urged in the locking direction with the locking portion 16 by the compression arm 21, and can be moved in the opposite locking direction about the fulcrum 23 by pushing the push button 22.

Further, a gap is provided so that the lower end of the clamp 20 and the bottom surface of the groove 17 do not come into contact with each other when the clamp 20 is locked in the locking portion 16 .

Further, 24 is a guide piece that enters and exits the guide groove 18 for left and right positioning.

The dust collection case 4 is provided with a compression plate 26 which is biased upward and is movable up and down, with a knob 25 projecting upward to compress dust.

In such a configuration, the dust collection case 4 and the main body case 1
The dust collecting case 4 is connected as shown in FIG.

Then, while pushing the clamp 13 and removing the clamp 13 from the engagement hole 14, lift the dust collection case 4 and lock the locking protrusion 1.
2 from the engagement recess 15.

In this way, when the push button 22 is pressed after removing the dust collection case 4 from the main body case 1, the clamp 20 rotates counterclockwise (FIG. 3) about the fulcrum 23 and locks with the locking portion 16. The state is released, and the lid body 7 rotates around the hinge 8 to close the opening 6.
to open.

At this time, the inner surface 10 of the lid body 7 is shaped like a smooth gutter toward the open end 11, and the locking portion 16 is formed at the open end 11.
does not protrude to the inner surface 10 side at all, so dust does not reach the open end 1.
1 along the inner surface 10 of the lid body 7 like a slide, and does not get caught.

At the same time, the dust does not scatter to the left or right, causing fine dust to fly up, and the dust can be handled hygienically without the need to handle it directly by hand.

Note that even if a shock or other force is applied from below the locking protrusion 12 when the dust collection case 4 is connected to the main body case 1 or when the dust collection case 4 is alone, the lower end of the crank 20 Since there is a gap between the clamp 20 and the locking part 16, the force is not transmitted to the clamp 20.
The lock will not be released inadvertently.

After discarding dust, the lid body 7 is rotated in the closing direction, and the clamp 2 is aligned with the guide piece 24 and the guide groove 18.
0 is easily and reliably locked in the locking part 16.

As mentioned above, this device is located between the inner surface of the lid body and the fixed locking part, and the locking part is formed at the open end, so this locking part prevents the dust from falling when disposing of dust. Dust can be easily and hygienically disposed of without causing any damage, and the lid can be opened and closed reliably by the locking device that locks and disconnects from the locking part.
In particular, since the locking device is installed in the dust collection case, when you open and close the locking part to open the lid, your hand is always above, so it is not contaminated by dust, which is hygienic. It has the following effects.
