Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning tool (carpet sweeper) equipped with a roller brush having relatively long bristles and a rotary brush body having a group of inclined piles. 55-
This is an improvement on the invention of No. 52072.

The carpet sweeper previously proposed by the applicant uses a roller brush for cleaning smooth floor surfaces, and for cleaning non-smooth pile fabric surfaces such as carpets: A rotatable rotary brush body having a pile group is used by lowering it, and the dust removed by the roller brush and the rotary brush body is collected without being divided into a dust collection chamber pivotally supported on the side wall of the container. It was designed to do so. As a result, the rough dust on the smooth floor surface is brushed up by the roller brush, and the lint and other fibrous dust on the surface of the non-smooth pile fabric are removed by the inclined pile group of the rotating brush body. The cleaning effect of the carpet sweeper is extremely good, as the rotary and dust-removing action of the fixed inclined pile group ensures reliable cleaning.

However, in the carpet sweeper with the above configuration, first of all, the dust collection chamber is pivoted to the wall of the container and cannot be removed from the container, so the dust can be disposed of by moving the container to the disposal site. It is necessary to carry it around, and at that location, the dust collection chamber must be rotated around its axis against the biasing force of an inverted V-shaped elastic pressing member, and the dust collection chamber must be passed through an opening extending from the bottom of the container.

Second, the coarse dust that is thrown up by the roller brush and the fibrous dust such as lint and pet hair that are scraped off by the cooperative action of the rotating brush body and the fixed brush that slides on it are the same. Since the dust is collected together in the outer chamber of the collection p', if the coarse dust thrown up by the roller brush falls between the inner wall surface of the container and the outer circumferential surface of the rotary brush body, the rotary brush body It has been found that the smooth swinging of the V2 chamber is obstructed, making it impossible to achieve a sufficient cleaning effect.This invention overcomes the above-mentioned deficiencies and improves it by attaching and detaching the collection V2 chamber to the vessel body. By using a flexible cassette type, dust can be disposed of by simply removing the dust collection chamber from the container and carrying it around, and the collection chamber can be divided into the first dust collection chamber and the second dust collection chamber by a partition wall. The coarse dust and fibrous dust that are removed by the roller brush and rotating brush body are collected in the first dust collection chamber and the second dust collection chamber, respectively, and the coarse dust is collected inside the chamber. To provide a carpet sweeper capable of ensuring smooth operation of a rotating brush body by preventing the brush body from falling between a wall surface and the outer peripheral surface of the rotating brush body.

The configuration of this invention will be explained based on FIG.

The carpet sweeper is equipped with a roller brush 4 rotated by a drive wheel 2 pivotally supported on the side wall 1a of the container body, a rotary brush body 11 having an inclined pile group 14, and a fixed flange 16 in sliding contact with the brush body 11. A cassette-type dust collection chamber 7 provided detachably from the body 1 is housed in the container 1 through the upper opening 1c of the container 1, as shown in FIG. The upper container 6 is pivotally connected to the upper container 6, and is held so as not to separate from the container 1. Dust collection room 7
is divided into a first dust collection chamber 7a and a second dust collection chamber 7b by a partition wall 8 provided in the width direction of the container body 1, and a roller brush 4
Coarse dust thrown up by the rotary brush body 11
The fibrous dust scraped off by the cooperative action of the inclined pile group 14 and the fixed inclined pile group 17 is divided into a first dust collecting chamber 7a and a second dust collecting chamber 7b and collected therein. ing.

The present invention will be described in detail below with reference to the drawings.

Between a pair of driving wheels 2 pivotally supported at the front of the vessel 1 and a rear wheel 3 provided at the rear of the vessel 1, there is a driven wheel that contacts the driving wheel 2 pivotally supported on the vessel side wall 1a. The roller brush 4, which is rotated by the roller brush 4a and has relatively long bristles 5 closely installed therein, is held by the inwardly bent piece 1e at the lower end of the container 1, and can be freely attached to and removed from the container. A dust collecting chamber 7 loaded with a dust collecting chamber 7 is provided, and a bell 6 which can be freely opened and closed is attached to the upper part of the dust collecting chamber 7, either integrally with the dust collecting chamber 7 or separately. The inside of this dust collection chamber 7 is divided into a first dust collection chamber 7 on the roller brush 4 side by a partition wall 8 provided in the width direction.
a and a second dust collection chamber 7b on the rear wheel 3 side, and is pivoted to the dust collection chamber side wall 7C from a widthwise elongated rectangular opening 1o formed in the bottom plate 9 of the second dust collection chamber 7b. , a rotary brush body 11 having an arcuate outer circumferential surface 11a is provided so as to protrude. A required number of contacts 12 are provided at an intermediate portion of the outer circumferential surface 11a of the rotary brush body 11 at appropriate intervals in the width direction and protrude outward. The material of this contactor 12 has appropriate abrasion resistance and flexibility with respect to the surface to be cleaned, and when the rotating brush body 11 is swung around the support shaft 13, it can be used to clean surfaces such as floors and tatami mats. An elastic material such as rubber that does not damage the surface to be cleaned, such as a carpet, is suitable.

On the outer circumferential surface 11a of the rotary brush rest 11 on the drive wheel 2 side, which is divided into front and rear parts by the contactor 12, there is provided a removable inclined pile group 14 which is laid down inside the second collection chamber 7b. The inner wall of the opening of the second dust collection chamber 7b into which the pile holder 15 is fitted and which can come into sliding contact with the inclined pile group 14 is provided with a fixed inclined pile group 17 that lies down in the same direction as the inclined pile group 14. A fixed brush 16 is provided. In Figures 1 and 4,
Although the inclined piles 14, 17 are provided on one side of the contact 12, they may be provided on both sides of the contact 12, as shown in FIG.

The rear @ 3 is normally provided on one side at the center in the width direction of the rear part of the vessel body 1, and is controlled by a height adjusting means 26 that slides vertically within a casing 18 formed in the vessel body. When the eleven inclined pile groups 14 are brought into contact with the non-smooth pile fabric surface, they function to separate from the pile fabric surface. The height adjustment means 26 pivots the support shaft 3a of the rear wheel 3 through a shaft hole 20a provided on the inner surface of a gate-shaped sliding member 20 fitted in the housing 18, and The moving member 2o is housed in a housing 18.
is biased upward by a spring 19.19 disposed between the inner surface of the bottom wall of the housing 18, and the upper surface of the sliding member 2.degree. The pressing portion of the switching lever 21 is normally placed on the upper surface of the sliding member 20, which the tip of the pressing portion 21b that contacts the pressing portion 21b of the held switching lever 21 to prevent upward movement comes into contact with. A retaining groove 20b is provided to hold 21b vertically.

The operating portion 21a of the switching lever 21 is connected to the opening 2 of the cover plate 23.
3a to the outside of the container body 1, and the switching lever 2 is
The housing 18 of the cover plate 23 whose switching angle is regulated
Attachment to the cover plate z3 is carried out by elastically fitting the engagement piece 23c of the cover plate z3 into the notch 18b provided in the upper side wall of the housing 18.

Therefore, when the switching lever 21 is rotated counterclockwise as shown in FIG. Since the member 20 is moved upward by the biasing force of the spring 19 and is prevented from moving upward by the side surface of the pressing portion 21b, the rotating brush body 11 in addition to the roller brush 4 is shown by the solid line in FIG. Bring it into contact with the surface A to be cleaned, such as a carpet. When the switching lever 21 is rotated clockwise as shown in FIG. 3(b), the sliding member 20 is moved to the lowest position against the urging force of the spring 19 by the pressing portion 21b rotating in the vertical direction. Since the rotary brush body 11 is pushed out to the position shown in FIG.

The upper lid 6 that covers the upper part of the dust collection chamber 7 is pivotally attached to the side wall 7C of the dust collection chamber on the rear wheel 3 side by a shaft 24, and the rear wall 7a of the dust collection chamber 7, ! : a protrusion 6a that comes into contact with each upper end of the partition wall 8;
6b, so that the second dust collection chamber 7b is not communicated with the first dust collection chamber 7a and the inside 1b of the container body, as shown in FIGS. 1 and 4.

The front wall 7θ of the dust collection chamber 7 is located inside the upper opening IC of the container body 1.
An opening 25 communicating with the roller brush 4 side is formed between the fj portion 1d and the front end locking ff1s6c of the upper lid 6 that engages with the fj portion 1d,
The coarse dust thrown up by the roller brush 4 is conveyed along the curved dust guide plate 28 installed above the roller brush 4 in the container body 1, and is collected into the first dust collection chamber 7a through the first opening 25. do.

27 is the switching lever 2 as shown in FIGS. 1 and 2.
A top lid locking member pivotally attached to the top surface of the vessel 1 on the first side;
A cassette-type dust collection chamber 7 loaded in the container body 1 is inserted into the upper lid 6.
The front end locking part 6c of the container 1 is engaged with the upper opening 1c of the container 1, and the elastic protruding piece 6d at the other end is locked with the upper lid locking member 27 to hold the container 1 so that it does not easily come off. do. When discarding the dust collected in the dust collection chamber 7, rotate the top lid locking member 27 in the direction of the arrow in FIG. By releasing the connection between 6C and the upper opening 1c of the container body 1, the cassette-type dust collection chamber 7 can be easily taken out from the container body 1, so that dust can be easily removed by simply opening the top lid 6. Moreover, it can be disposed of without getting your hands dirty. Note that the upper M6 does not necessarily need to be pivoted to the side wall 7C of the dust collection chamber on the rear wheel 3 side. For example, the upper M6 may be pivoted to the side wall 1a of the container body 1 near the front end of the upper opening 1c, and The elastic protruding piece 6d at the end may be locked by the upper lid locking member 27.

Next, the operation will be explained.

When using the carpet sweeper to clean the surface of a carpet or pile fabric for inch rear use, the switching lever 21 can be switched to the position shown in FIG. 3(a), and the rear wheel held by the sliding member 2o 3 is moved upward by the urging force of the spring 19, so that the inclined pile group 14 of the rotary brush body 11 comes into contact with the surface A to be cleaned, such as a carpet.

In this state, if the operating handle 29 is pushed to move the container 1 forward in the direction of the solid arrow a with respect to the surface to be cleaned A, the driving wheel 2 will rotate counterclockwise and the driven wheel 4a coaxial with the roller brush 4 will rotate. Since the roller brush 4 rotates in a clockwise direction, the roller brush 4 also rotates in the same direction, and the relatively large coarse dust on the pile surface of the carpet etc. is thrown upward by the bristles 5, and the dust guiding plate 28 above the roller brush 4 blows it upward. The dust is guided through the entire opening 25 and collected into the first dust collection chamber 7a.

On the other hand, during the forward movement of the roller brush 4, the semi-cylindrical rotating brush body 11 pivotally mounted in the second dust collection chamber 7b has a plurality of contacts 12 protruding from its outer circumferential surface. The edge 10a of the lower opening 10 of the second dust collection chamber 7b while sliding on the top.
The rotation of the rotating brush body 11 stops upon hitting the brush body 11 . However, since the forward motion of the container body 1 continues, the inclined pile group 14 of the rotary brush body 11 is not only on the surface of the carpet, etc., but also entangled within the pile group, causing the roller brush 4 to Even leftover dust, lint, and fibrous dust such as pet hair are scraped off between the inclined pile groups 14 so as to be combed.

Next, when the entire container body 1 is pulled in the direction of the dotted line arrow a' using the operation handle 29, the rotary brush body 11 is moved from the contactor 1.
2 slides and abuts against the edge 10b of the opening 10 and stops its rotation. Meanwhile, the various dust that had been scraped up on the inclined pile group 14 during the previous forward movement is thrown down in the same direction when the fixed brush 16, which is inclined in the same direction, slides on the inclined pile group 17. It is not scraped off by the pile group 17, but is retained in the inclined pile group 14 as it is. On the other hand, the roller brush 4 rotates in the opposite direction to that when the container body 1 was moved forward last time, and the coarse dust on the surface A to be cleaned is removed from the front wall 7e of the dust collection chamber 7 by the bristles 5.
Dust is collected in the dust collection chamber 7'a.

When the container 1 is pushed in the direction indicated by the solid arrow a and moved forward again, the roller brush 4 cleans relatively coarse dust on the pile surface of the carpet etc. by rotating clockwise, as explained during the previous forward movement. The dust is collected in the first collection M chamber 7a.

On the other hand, when the rotary brush body 11 is rotated counterclockwise by the action of the contactor 12, the fibrous dust collected and retained in the inclined pile group 4 is removed by the rotation of the rotary brush body 11. Fixed brush 1 lying in the opposite direction
The rotary brush body 11 is scraped by the inclined pile group 17 of 6.
from there to the fixed brush 16. As a result, the inclined pile group 14, which has been cleaned with dust and the like removed, is pulled out between the openings 10 and again scrapes up fibrous dust and the like on the surface A to be cleaned, such as a carpet.

When the container body 1 is further pulled in the direction of the dotted arrow a', the roller brush 4 rotates counterclockwise and sweeps the coarse dust on the pile surface through the entire opening 25 from the front wall 70 side, as described above. The dust is collected in the first dust collection chamber 7a. On the other hand, the dust that was scraped from the inclined pile group 14 to the fixed inclined pile group 17 during the previous backward movement is combed out from between the fixed inclined pile groups 17 by the inclined pile group 14 of the rotating brush body 11. However, as explained last time, the fibrous dust and the like that had been scraped up by the inclined pile group 14 of the rotating brush body 11 are pushed out into the second dust collection chamber 7b by the inclined pile group 17 of the fixed brush 16. Since it is inclined in the same direction as the inclined pile group 14 of the rotating brush body 11, it is held as it is in the inclined pile group 14 without being scraped off.

By repeating the above forward and backward movements nine times, the coarse dust on the pile surface of the carpet etc. can be removed using the roller brush 4.
During the reciprocation, the dust is thrown up into the first dust collection chamber 7a, but lint, pet hair, and other fibrous dust are
During the first forward movement, the inclined pile group 14 of the rotary brush body 11 scrapes up the piles, but during the first backward movement, the inclined pile group 17 of the fixed brush 16 is in the same falling direction, so that the inclined pile group 14 The dust between them will remain as it is. During the second forward movement, the inclined pile group 14 slides on the fixed inclined pile group 17 and opens the opening i.

Since the dust that was initially held in the inclined pile group 14 is scraped off by the fixed inclined pile group 17, the cleaned inclined pile group 14 again collects new dust. Next, when moving to the second backward movement, the inclined pile group 14 is replaced by the fixed inclined pile group 1.
The dust that was previously scraped off by the inclined pile group 17 while sliding on the inclined pile group 7 is pushed forward like a comb and is finally pushed into the second dust collection chamber 7b, but the inclined pile group 4 The newly collected dust will be retained as it was the last time.

That is, when cleaning all the fibrous dust from a carpet, etc., as described in detail above, the fixed inclined pile group 17 scrapes off the dust collected by the inclined pile group 14 of the rotating brush body 11, and then the inclined pile group 17 scrapes off the dust, and then This cleaning action is completed when the pile group 14 pushes this dust forward with its bristles and pushes it out into the second dust collection chamber 7b.

When cleaning smooth surfaces to be cleaned such as tatami mats and floors with the carpet sweeper of the present invention, switch the switching lever 21 to the position shown in FIG. If the roller brush 4 is pushed down to the position shown by , the roller brush 4 close to the drive wheel 2 will come into contact with the surface to be cleaned at the same position as when cleaning a carpet or the like, so the cleaning effect will not be different at all. Furthermore, since the rotary brush body 11 is in a position raised from the surface to be cleaned, there is no fear that the floor or tatami mats will be damaged by the contacts 12, and the roller brush body 11 described above
The dust on the smooth surface to be cleaned is collected by the first dust collecting g7.
Dust can be collected in a.

-The above operation is performed by the contact 1 on the rotating brush body 11.
This is an explanation of the case where the inclined pile group 14 is provided on one side of the rotary brush body 11 and the fixed brush 16. When the chamber 7A (see Fig. 5) is used, the fibrous dust, etc. left without being cleaned by the bristles 5 of the roller brush 4 is removed in either direction of the forward and backward movement of the vessel body 1. The dust can be scraped off alternately and finally pushed out and stored in the dust collection chamber 7A.

As explained above, this invention has a removable cassette-type dust collection chamber loaded into the container body, and a partition wall inside the dust collection chamber to remove relatively coarse dust, lint, and hair from the bed. Since the dust is collected separately from fibrous dust such as , prevents the coarse dust thrown up by the four-sided brush from falling between the inner wall surface of the container body and the outer peripheral surface of the rotary brush body, and maintains smooth operation of the rotary brush body for a long period of time. be able to.
