Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a vacuum cleaner, and in particular, a built-in collector I smoothes the flow of air and dust in a communication section where a filter and a duct are connected, and removes dust. The present invention relates to a vacuum cleaner suitable for facilitating removal and reducing noise.

[Background of the invention]

Conventionally, so-called applied-type vacuum cleaners in which the dust suction part and the blower chamber were integrated were disclosed in Utility Model Publication No. 55-7995.
There is an invention described in No. 3, which is No. 11.12.1.
As shown in FIG. 3, a hole 12 is formed in the bent part of the abbreviated bent pipe 119 formed at the connection part between the main body 104 and the hose 107.
A cover 118 is provided to open and close the hole 120 and the hole 120 to remove clogged dust.

However, in order to eliminate dust clogging, the inner surface of the lid body 118 is made into a gently curved surface, so that the shape of the bent tube 119 extends largely to the outside of the main body 104, making it difficult to clean areas with little space between it and the floor surface. In addition, when making the plastic mold for the lid body 118, it is preferable to make the wall thickness uniform, but since the shape of the inner curved surface of the lid body 118 is determined by the external shape, the design degrees of freedom are restricted,
Furthermore, the impact noise caused by the dust colliding with the inner surface of the lid 118 is large, and there is a risk that the lid 118 may be damaged in some cases. [Objective of the Invention] The present invention solves the above problems. To provide a vacuum cleaner with easy removal of dust, low impact noise caused by dust, effective prevention of damage to bent parts, and excellent appearance.

[Summary of the invention]

The present invention has been made to achieve the above objects,
The bent portion is characterized by having a lid having a "slatted" rib that forms a concave curved surface along the streamlines of air and dust, and an elastic packing.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of one embodiment of the present invention, and FIG.
A longitudinal cross-sectional view of the figure is shown. In Figs. 1 and 2, the main parts of the dust suction case 1 are an inlet 2, a bottom plate 5 holding a rotating brush body 4 having bristles 3 on its cylindrical surface, and a front wheel provided on the lower surface that contacts the floor. A bumper 8 made of an elastic cushioning material is provided on the front surface of the rear-6 (consisting of a dust suction case).

Further, the dust suction case 1 is fitted so as to be rotatable by a predetermined angle about the center 4@C-c of the blower chamber 11 that houses the electric blower 12.

Adjacent to the blower room 11 is a main body case 1o.

Duct 14 led from dust suction case 1 and dust collection filter 1
It has 6 built-in. Also, the front cover 2 of the main body case 1o
8 and is locked to the main body 10 by a clamp 29.

A handle 37 is provided at the other end of the main body case 10, and a switch 36 is disposed on the surface of the main body case 10 near the handle 37.

Next, the internal structure of this embodiment will be explained.

In FIG. 2, the shaft 13 of the electric blower 12 and the rotating brush body 4 are connected by a belt 9 and a set of transmission pulleys (not shown), thereby causing the rotating brush body 4 to rotate. By aligning the axis of the shaft 13 with the center line c-c in FIG. 1, the initial tension on the belt 9 does not vary when the dust suction case 1 is rotated.

Duct 14 and dust filter 16 which are the central part of the present invention
The details of the portion where the two communicate with each other are shown in FIGS. 3 to 5'.

That is, the eye portion 17 of the dust collecting filter 16 is fixed to the filter holder 18 by a claw 19 and a holder holding portion 2o. Furthermore, the filter holder 18 is
It is detachably attached to the filter base 22 into which the filter 1 is fitted. Note that the filter base 22 and main body case 10
are fastened together with screws 44 via bosses 42 and 43, respectively.

The end of the duct 14 opposite to the dust suction case forms a T-shape 23 and is inserted into the filter base 22. The T-shape 2
3, one end is in contact with the rock band 21 of the dust collection filter 16, and the other end is connected to the opening of the main body case 10, and the opening is connected to a lid that can be opened and closed about the fulcrum part 25. The insertion portion 47 of the body 24 is inserted into the inner diameter 49 portion of the T-shape 23 via the packing 45 to close it.

The details of the structure of the lid body 24 are as shown in FIGS. 6 and 7, including an insertion part 47 having a plurality of ribs 47a arranged side by side to form a "slatted" shape, and a plastic insert 47 as shown in FIGS. 8 and 9. Or a packing 45 made of an elastic cushioning material such as rubber,
The insertion portion 47 is fitted with a crown, and at this time, the side shapes of both are aligned so that they match each other.

The upper part of the lid 2.4 has a relief part 26 when the lid 24 is opened, as shown in FIG. 5, and the lower part of the lid 24 has a four part 46 and a protrusion 27.

In FIG. 2, each of the front parts 28 can be removed from the main body case 10 by pulling up the clamp 29 against the elasticity of the clamp spring 30.
It is possible to take out 6.

A cord reel 32 is provided at the upper part of the R4 chamber 15 in the main body case 10, and a power cord 31 is wound thereon. The cord reel 32 is fixed to the main body case 10 with screws 33.

In the vacuum cleaner configured as described above, the vacuum cleaner is operated by pulling out the power cord wound around the cord reel 32, connecting it to a power source, and turning on the switch 36.

Dust on the floor is removed through the suction chamber 21, rotating brush body 4, and duct 14.
, and is collected in the dust collection filter 16 through the T-shape 23.

At this time, when the dust passes through the T-shape 23, the insertion portion 47
By causing the dust to jump along the curved surface and guiding it to the dust collection filter 16 side, clogging with dust can be prevented.

Even if dust should come into contact with the T-shape 23, the dust can be easily removed by opening the lid 24.

Moreover, as shown in FIG. 10, the outer surface of the lid 24 can be placed on the same plane as the main case 1o, so as shown in FIG. 6. The elasticity of the gasket 45 fitted in the insertion part 47 of the lid body 24 makes it possible to clean places with a small gap between the floor and the floor. Dust is caused to jump and guided to the inlet side of the dust collecting filter 16.

Figure 5' shows an accessory hose 3 attached to one end of the T-shaped 23 with the lid 24 open.
9 is inserted.

〔Effect of the invention〕

By implementing the present invention, it is possible to achieve remarkable effects in smoothing the flow of dust at the bent portion of the duct, reducing dust clogging, and preventing breakage of the duct by reducing dust collision noise and mitigating impact force.
