Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner, and an object of the present invention is to provide a vacuum cleaner that can be easily thrown away without causing dust to be thrown up.

A first embodiment of the present invention will be described based on FIGS. 1 and 2.

Reference numeral 1 denotes a dust collecting case which is detachably connected to a main body case (not shown) in which an electric blower is built-in, and has a handle 2 formed at its upper part and a suction port 3 formed at its front end.

Further, a filter section 4 is provided at the rear end of the inside of the dust collection case 1.

The filter section 4 consists of a filter frame 5, a suction surface 6 of the filter frame 5 which is a net filter, a sponge-like filter 7, and a filter 8 folded in a zigzag shape.

A communication port 10 for communicating with the main body case is formed in the rear end 9 of the filter frame 5, and a dust removal body 11 for vibrating the filter 8 is attached.

An opening 13 for disposing of dust is provided at the bottom of the dust collection case 1.
is formed.

Further, a lid 14 for opening and closing the opening 3 is rotatably attached at its front end to a hinge 15 provided on the dust collection case 1.

This lid body 14 has walls 16 formed on both sides thereof and an inner surface 17.
has a smooth gutter shape from the front end toward the open end 18, and is open on the open end 18 side.

Further, a guide groove 19 and a locking piece 20 are formed in the open end 18 so as not to protrude into the inner surface 17.

A protrusion portion is formed at the lower part of the rear end portion 9 of the filter frame 5 in a shape that matches the inner surface 17 of the lid body 14 and that protrudes downward and serves as a guide when the lid body 14 is closed. A locking device 21 that engages and disengages from the guide groove 19 and the locking piece 20 is attached to the guide groove 19 .

That is, this locking device 21 is always urged to lock with the guide piece 22 that enters the guide groove 19 and performs left and right positioning, and the locking piece 20, and is locked by pressing the push button 23. It consists of a locking piece 24 that is released.

Further, a locking protrusion 25 is provided on the lower edge of the open end 18 of the lid body 14.
A lamp 26 is provided at the upper rear end of the dust collection case 1 and is slidable while being biased upward, and the locking projection 25 and clamp 26 allow the dust collection case 1 to be attached to and removed from the main body case. The dust collection case 1 has a knob 2.
A compression plate 28 that compresses dust by protruding upward is provided so as to be able to move up and down while being biased upward.

In such a configuration, the dust collection case 1 is connected to the main body case for cleaning, and the dust collected in the dust collection case 1 is compressed by the compression plate 28 by pressing the knob 27.

Then, press the clamp 26 to lift the dust collection case 1 and remove it from the main case.

When the push button 23 is pressed, the locking pieces 20 and 24 are unlocked, and the lid body 14 rotates around the hinge 15 to open the opening 13.

As a result, the compressed dust falls. At this time, the walls 16 are formed on both sides of the lid body 14, and the inner surface 17 is smoothly formed toward the open end 18, so that there are no unevenness that can become an obstacle. falls easily along the inner surface 17 of the lid 14 like a slide.

At the same time, dust is not scattered from side to side and fine dust does not rise diagonally, allowing the dust to be disposed of hygienically.

Furthermore, when closing the lid 14, the protruding portion of the filter frame 5 acts as a guide to determine the position of the lid 14, so the position of the locking piece 20 relative to the locking device 21 is accurate, and the closing operation is easy. Yes Furthermore, since the protruding portion of the filter frame 5 prevents the lid 14 from moving in the lateral direction, the strength of the lid 14 in the closed state is high.

Next, a second embodiment of the present invention will be described based on FIGS. 3 and 4.

The same parts as in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, a concave portion 29 is formed on the lower surface of the lid body 14 at a slightly open end 18, has the same thickness, and projects inwardly, and a wheel 30 is mounted within this concave portion 29.

Furthermore, the inner surface 32 of the lid 14 excluding the convex portion 31 formed by the recess 29 is formed smoothly and continues to the open end 18.

That is, a spoon-shaped recess 34 is formed on the front end side of the convex portion 31, and the external shape thereof is a sled-like portion 33.
A gutter-shaped portion 35 is formed on both sides toward the open end 18 and continues with the recessed portion 34. In such a configuration, the dust collection case 1 is connected to the main body case as in the above embodiment. 0 At this time, the vacuum cleaner moves, but when going over a threshold etc., the wheels 30 get over the threshold while being guided by the sled part 33 of the lid body 14, so the vacuum cleaner can move smoothly. Since the wheels 30 are mounted in the recessed portion 29 and both sides are made into convex portions by the gutter-like portions 35, it is difficult to fall over.

When disposing of dust, the push button 23 is pressed to rotate the lid body 14 and open the opening 13.

At this time, although the convex portion 31 is formed on the lid body 14,
Since the inner surface 32 around it is surrounded by the wall 16 and has a concave portion 34 and a gutter-like portion 35 that are continuous toward the open end 18, dust is scattered left and right by the wall 16, causing fine dust to fly up. It can easily fall along the inner surface 32 and can be disposed of hygienically.

In this way, even when the wheels 30 are attached to the lid 14 so that they do not fall down easily, the same effects as in the embodiment described above can be obtained.

As described above, the present invention is provided with a rotatable lid having walls on both sides that protrude downward from the edge of the opening formed at the bottom of the dust collection case. The internal volume can be substantially increased, and when the lid is opened, the opening becomes larger by the amount of wall that remains, which prevents dust from clogging and prevents dust from falling. The wall also acts as a guide and guides the user to the open end side, which prevents fine dust from flying up due to dust scattering from side to side. The piece is engaged with a locking device provided on the filter frame to maintain the closed state, and a part of the filter frame is made to protrude downward in a shape that matches the inner surface of the lid to prevent the lid from closing. Since it is used as a guide when closing, the locking piece can be reliably engaged with the locking device when the lid is closed.
The closing operation is easy, and since the filter frame restricts the lateral movement of the lid, the strength of the lid when attached is high.
