Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning tool that can switch the operation of a floating brush body having a group of inclined piles that lie down depending on the type of surface to be cleaned and the type of dust.

Generally, household cleaning equipment includes electric vacuum cleaners and manual vacuum cleaners equipped with bristled roll brushes.

However, these cleaning tools can remove dust from smooth surfaces such as tatami mats and hallways, and small pieces of food, paper, and other easily absorbed dust that simply rests on the surface of pile fabrics such as carpets. Fibrous dust such as lint, cotton dust, and hair generated from clothes that easily get tangled in the naps of pile fabrics may be difficult to remove, or they may get tangled with the bristles, significantly reducing the dust removal effect. I couldn't clean it enough.

The present invention solves the above-mentioned disadvantages, and includes a floating brush body equipped with a group of inclined piles lying in one direction, suitable for cleaning pile fabrics such as carpets, and a bristle brush suitable for cleaning tatami mats and smooth floors. By attaching it to a conventional cleaning tool in a switchable manner as explained later, it maximizes its functionality not only for cleaning flat surfaces such as tatami mats and hallways, but also for cleaning carpets for which bristle brushes were insufficient. The purpose is to provide cleaning tools that can

To explain the embodiment, 1 is a drive wheel which is rotated on the surface to be cleaned by the forward and backward movement of the main body A, and the drive wheel 1 is connected to a shaft 2.
It is rotatably pivoted to the side wall 3a of the dust collection chamber 3 provided in the front and back direction of the lower part of the main body A.

A passive wheel 4 is provided between the driving wheels 1, 1 and is rotated in contact with the driving wheels 1, 1.A shaft 5 of the passive wheel 4 has bristles 6 with relatively long hairs closely disposed thereon to form a roll. Brush number 7.

The dust collection chambers 3, 3 are close to the front and back of the roll brush 7 and open upward, but if the dust collection chamber 3 is constructed in a cassette type, one of the dust collection chambers 3 may be omitted.

A part of the bottom plate 8 of the dust collection chamber 3 is provided with an elongated rectangular opening 9 in the width direction, and from the part of the opening 9 there is a part of the arc-shaped circumferential side 10 on the drive wheel 1 side. A floating brush body 12 having a group of inclined piles 11 lying down toward the dust collection chamber 3
A portion thereof is exposed from the side wall 3a of the shaft 3a while being rotatably held by a support shaft 13.

On the arc-shaped inner wall surface 14 of the dust collection chamber 3 that faces the arc-shaped circumferential side surface 10 when the floating brush body 12 rotates around the support shaft 13, there are inclined piles laid down in the same direction as the inclined pile group 11. Group 15 is attached to form stationary brush 16.

Reference numeral 17 denotes a contact provided at an intermediate portion of the circumferential side surface 10 of the floating brush body 12 at an appropriate interval in the width direction;
7 has appropriate abrasion resistance and flexibility between it and the surface to be cleaned, for example, and when the floating brush body 12 is rotated about the support shaft 13, it can be used to clean the surface to be cleaned such as a carpet. Elastomers that do not damage are suitable.

The contactor 17 may be integrally formed with a protrusion on the arcuate circumferential side surface 10, or may be made separately and attached.

The contact 17 may have one or three protrusions instead of the two shown in the figure.

Reference numeral 18 denotes an elastic pressing member such as an inverted V-shaped spring attached to the protruding pieces 19, 19 at the lower end of the dust collecting chambers 3, 3 on the roll brush 7 side. It rotates the chambers 3, 3 clockwise and counterclockwise around the shafts 2, 2, respectively, and serves to separate them from the surface to be cleaned and to press and hold the dust collection chambers 3, 3 at a predetermined position within the main body A. .

Reference numeral 20 denotes a shock-absorbing elastic body attached to the inside of the main body A. The elastic body 20 is used when the left dust collection chamber 3 rotates around the shaft 2, and when the floating brush body 12 rotates around the support shaft 13. Reduces the impact when the vehicle is moved and collides with the vehicle.

A part of the main body A corresponding to the upper end surface of the left dust collection chamber 3 to which the floating brush body 12 is attached is provided with a part of the main body A that rotates the left dust collection chamber 3 counterclockwise around the shaft 2 against the pressing force of the elastic pressing member 18. A switching device 21 is provided which rotates in the direction and brings the circumferential side surface 10 of the floating brush body 12 into contact with the surface to be cleaned.

On the bottom plate 8 of the left dust collection chamber 3, sliding auxiliary parts 2 are provided near both left and right ends in the width direction on the main body A side from the opening 9 in the direction of the surface to be cleaned.
2 is attached, and when the floating brush body 12 is pushed out toward the surface to be cleaned by the switching device 21, it comes into contact with the surface to be cleaned, and the inclined pile group 11 is attached to the peripheral side surface 10 of the floating brush body 12. The main body A is adjusted so that it does not become too deeply intertwined with the carpet surface to be cleaned or the pile surface of the interior pile fabric, so that the main body A can smoothly move back and forth.

Reference numeral 23 denotes a push rod used to move the main body A back and forth, and the push rod 23 is attached to the center of the upper surface of the main body A so as to be rotatable in the front and rear directions around a shaft 24.

an opposing wall 3b that partitions the roll brush 7 side of the dust collection chambers 3, 3;
Comb-like members 25 for removing lint are provided on the upper end surface of the roll brush 7 toward the bristles 6 at appropriate intervals in the length direction of the roll brush 7.
is installed.

In the above embodiment, when cleaning the surface to be cleaned of a carpet or pile fabric for interior design, the switching device 2
1 to rotate the left dust collection chamber 3 counterclockwise around the shaft 2 and push out the peripheral side surface 10 of the floating brush body 12 toward the pile fabric side of the surface to be cleaned, the floating brush body 12 will slide. The auxiliary portion 22 pushes the inclined pile group 11 to a position where it is not too deeply intertwined with the pile fabric and comes into contact with the surface to be cleaned.

Next, push the push rod 23 to move the main body A over the surface to be cleaned in the direction of arrow a.
When the main body A is moved forward, the driving wheels 1, 1 rotate in the opposite direction, and the driven wheels 4 in contact with these rotate in the direction of movement of the main body A, so the roll brush 7 also rotates in the same direction, and the roller brush 7 rotates in the same direction, cleaning carpets, etc. Roll brush 7 removes relatively coarse dust on the pile surface.
As is known, the dust particles are splashed upward by the bristles 6 and collected in the dust collection chamber 3 on the traveling direction side.

On the other hand, the floating brush body 12 attached to the dust collection chamber 3 on the left side is located at a position where the contact 17 receives a frictional force in the opposite direction from the pile surface such as a carpet, and brings the inclined pile group 11 into contact with the surface to be cleaned. After pulling out the shock absorbing elastic body 20
Since the rotation is stopped by the bristles 6 of the roll brush 7, fluff, lint, fine dust, etc. left on the pile surface of the carpet etc. without being cleaned by the bristles 6 of the roll brush 7 are removed by the countless fine bristles of the inclined pile group 11. Scraped between the tips.

Next, when the main body A is pulled in the direction of the arrow a' by the push rod 23, the driving wheels 1, 1 rotate in the opposite direction to the arrow a', so the roll brush 7 is moved in the direction of the arrow a' via the driven wheel 4. While rotating, relatively coarse dust on the pile surface of the carpet etc. is thrown up by the bristles 6 into the dust collection chamber 3 on the opposite side of the main body A.

On the other hand, the floating brush body 12 rotates in the direction opposite to arrow a', that is, in the direction opposite to the direction of movement of the main body A, due to the frictional action of the contactor 17 that comes into contact with a pile surface such as a carpet, and is captured by the inclined pile group 11. The fluff, lint, fine dust, etc. that have been left behind are moved as they are to a position facing the inclined pile group 15 of the fixed brush 16 which is inclined in the same direction as the inclined pile group 11.

When the push rod 23 is pushed again to move the main body A forward in the direction shown by the arrow a, the roll brush 7 removes relatively coarse dust on the pile surface of the carpet etc. on the moving direction side, as explained in the previous forward movement. However, the floating brush body 12 is rotated clockwise around the support shaft 13 by the action of the contactor 17 until rotation is stopped by the shock absorbing elastic body 20.

During this rotation, the fluff, lint, fine dust, etc. that have been captured on the inclined pile group 11 of the floating brush body 12 are transferred to the inclined pile group of the fixed brush 16, which is inclined in the opposite direction to the rotating direction of the floating brush body 12. The inclined pile group 11 is scraped by the group 15 and transferred from the floating brush body 12 to the fixed brush 16, so that the inclined pile group 11, which has been cleaned of dust and the like, is rotated by the contactor 17 and then transferred to the surface to be cleaned again. Captures dust on top.

Furthermore, if the main body A is pulled in the direction of arrow a' once again to perform a backward movement, the roll brush 7 will move the relatively coarse dust on the pile surface of the carpet to the direction of movement, as explained in the case of the previous backward movement. However, the inclined pile group 11 of the movable brush body 12 throws up newly captured fuzz, lint, fine dust, etc. by the action of the contactor 17 into the inclined pile group 15 of the fixed brush 16. At the same time, the dust that was previously held in the inclined pile group 15 of the fixed brush 16 is further pushed out in the inclined direction of the pile, that is, inward by the inclined pile group 11 of the floating brush body 12, and is removed from the fixed brush 16. It separates and accumulates in the dust collection chamber 3.

If the above-mentioned back and forth movement is repeated, the bristles 6 of the roll brush 7 will each time blow up relatively coarse dust etc. on the pile surface of the carpet etc. into the left and right dust collection chambers 3, 3, respectively, but the floating brush body 12 The slanted pile group 11 captures fuzz, lint, or relatively fine dust left on the pile surface of a carpet only in the case of one-way movement, and the slanted pile group 16 of the fixed brush 16 is in sliding contact with the slanted pile group 11. The dust and the like that is scraped off during the slanted pile group 15 and held in the slanted pile group 15 can be removed to the dust collection chamber 3 by the slanted brush 11 of the floating brush body 12 before the next rotational movement.

When cleaning surfaces to be cleaned such as tatami mats and floors using the cleaning tool of the present invention, operate the switching device 21 to release the force that was pressing the left dust collection chamber 3 counterclockwise around the shaft 2. Then, the left dust collection chamber 3 is rotated clockwise around the shaft 2 by the elastic action of the elastic pressing member 18, so that the floating brush body 12 is moved by the sliding auxiliary part provided on the bottom plate 8 of the dust collection chamber 3. 22 and away from the surface to be cleaned, resulting in the state shown in FIG.

After bringing the main body A to this state, move the main body A along the arrows a and a' on the surface to be cleaned.
If it moves back and forth alternately in the directions shown, the dust on tatami mats, floors, etc. will be removed by the driving wheels 1, 1 through the passive wheels 4 in the same direction as the moving direction of the main body A, similar to conventional cleaning tools. The rotating and sliding motion of the roll brush 7 allows for sufficient cleaning.

Dust is removed from surfaces to be cleaned such as carpets and floors, and
3, the dust collected in one of them, for example, the lower end on the roll brush 7 side of the left dust collection chamber 3, is rotated around the shaft 2 in a direction opposite to the rotational moment of the elastic pressing member 18, as shown by arrow b in FIG. When the elastic pressing member 18 is rotated by a certain angle in the direction, the elastic pressing member 18 is displaced as shown by the two-dot chain line in FIG. Unlike before, the left dust collection chamber 3 is opened by rotating counterclockwise about the shaft 2, so that the dust accumulated in the left dust collection chamber 3 can be easily removed.

The right dust collection chamber 3 can be similarly opened by pressing in the direction shown by arrow b' to remove dust.

That is, according to the cleaning tool according to the present invention, the switching device 2
By moving the movable brush body 12 and sliding auxiliary part 22 in and out of the surface to be cleaned to a pre-adjusted position by the operation in step 1, it is possible to remove the movable brush body 12 and the sliding auxiliary part 22 from the surface to be cleaned to a predetermined position. It can be reciprocated without any trouble and cleaning can be done efficiently with just one cleaning tool.

In the above embodiment, the inclined pile group 1 is provided only on one side of the contactor 17 provided on the peripheral side surface 10 of the floating brush body 12.
1 is provided, but as shown in FIG.
It is also possible to provide groups of inclined piles 11, 11' that lie down toward the inner side of the dust collection chamber 3 with the boundary between them, and to provide fixed brushes 16, 16' corresponding to the groups of inclined piles 11, 11'.

When the cleaning tool is configured in this way, the bristles 6 of the roll brush 7 remove fluff, lint, fine dust, etc. that have not been cleaned by the bristles 6 of the roll brush 7 in either direction as the main body A moves back and forth. 11, 11', and as already explained in FIGS. 1 to 6, the fixed brushes 16, 16
The fuzz, dust, etc. that have been scraped off by either of the above can be pushed out into the dust collection chamber 3.

Therefore, it is possible to further improve the cleaning effect of pile fabrics such as carpets, to which lint, cotton dust, hair, and other fibrous dust easily adheres to the surface to be cleaned.

It goes without saying that the floating brush body 12, which was attached to either one of the dust collection chambers 3, 3 of the main body A in the above embodiments, may be attached to both of the dust collection chambers 3, 3 in the front and rear directions. be.
