The present invention relates to a vacuum cleaner and more particularly to a brush assembly of a vacuum cleaner.

In general, the vacuum cleaner is a device for cleaning by applying a suction force to the moving brush assembly in contact with the surface to be cleaned by sucking the air together with the dirt on the surface to be cleaned. Therefore, the brush assembly is formed in a shape that can smoothly suck in air containing dirt (hereinafter referred to as dirt-containing air) from the surface to be cleaned.

Such a brush assembly includes a brush body. One example of a brush body is shown in FIG. 1. Referring to FIG. 1, the lower surface of the brush body 1 is provided with a suction port 2 communicating with a main body (not shown) of the vacuum cleaner. The lower surface of the brush body 1 is provided with suction passages 3 and 4 which are passages through which dirt-containing air is sucked to both sides of the suction port 2. The suction passages 3 and 4 are formed in a U-shape whose cross section is flat on the lower surface of the brush body 1, one end of which is opened to the side surfaces 5 and 6 of the brush body 1, and the other end thereof is the suction port. It is open to (2).

Therefore, when the vacuum cleaner operates and suction power is generated, the dirt-containing air flows from both side surfaces 5 and 6 of the suction flow paths 3 and 4 in the direction of the arrow A to flow to the suction port 2. The dirt-containing air sucked into the suction port 2 is moved to the main body of the vacuum cleaner. The dirt-containing air moved to the vacuum cleaner is separated / collected by a dust collector (not shown) installed in the vacuum cleaner. The dirt is removed and clean air is discharged to the outside of the vacuum cleaner.

By the way, the brush body 1 of the brush assembly (not shown) according to the prior art contains dirts sucked from the suction passages 3 and 4 on both sides because the suction passages 3 and 4 are almost straight. Air impinges on the inlet 2 to generate noise. Therefore, it is desirable to reduce this noise whenever possible.

In addition, when dirt is attached to the surface to be cleaned, which does not fall only by the suction force of the vacuum cleaner, there is a problem in that cleaning is inconvenient because the user has to remove the dirt attached to the surface to be cleaned and suck it with a vacuum cleaner.

The present invention has been made in view of the above problems, it is an object of the present invention to provide a brush assembly of a vacuum cleaner that can reduce the noise generated by the air sucked into the inlet.

Another object of the present invention is to provide a brush assembly of a vacuum cleaner capable of removing and sucking dirt attached to a surface to be cleaned.

An object of the present invention as described above, the brush body is in communication with the vacuum cleaner body and having a suction port for the suction force acts; First and second suction passages formed at both sides of the suction port on the lower surface of the brush body and into which dirt-containing air is sucked; And a plurality of hair removing members installed in parallel with the first and second suction passages inside the first and second suction passages, the inclined ends of which are inclined toward the suction ports. Is achieved by providing

In this case, it is preferable that the angle of the plurality of hair removing members inclined with respect to the bottom surfaces of the first and second suction passages is 40 degrees to 50 degrees.

In addition, the brush assembly of the vacuum cleaner according to the present invention, it is preferable to use a hair removing member made of an elastic material.

At this time, the whisk member is formed in a conical shape, it is preferable to further include a whisk on the tip. The hair pores are preferably spherical.

Hereinafter, a brush assembly of a vacuum cleaner according to an embodiment of the present invention will be described with reference to the accompanying drawings. However, in the following description of the present invention, if it is determined that the detailed description of the related known functions or components may unnecessarily obscure the subject matter of the present invention, the detailed description and specific illustration thereof will be omitted.

2 to 4, the brush assembly 10 of the vacuum cleaner according to an embodiment of the present invention includes a brush body 20, a plurality of hair removing members 30, a cover 12, and a pair. The wheel 15 of the.

The brush body 20 is composed of a head 21 and the leg 29, the head 21 and the leg 29 forms a substantially "T" shape. An extension tube 90 is connected to the rear end of the leg 29 of the brush body 20. Extension tube 90 connects the vacuum cleaner body (not shown) and the brush assembly 10 so that the dirt-containing air sucked into the brush assembly 10 is moved to the vacuum cleaner body. In addition, a dirt passage (not shown) is provided inside the leg 29 of the brush body 20 to communicate with the vacuum cleaner body through the extension tube 90. The suction port 22 is formed in the center of the head 21 of the brush body 20. The suction port 22 is formed on the lower surface of the head 21 of the brush body 20 and communicates with the dirt flow path. Therefore, the suction port 22 communicates with the vacuum cleaner main body through the dirt passage and the extension pipe 90.

In addition, first and second suction passages 23 and 24 are formed at both sides of the suction port 22 on the lower surface of the brush body 20. Thus, the dirt present on the surfaces to be cleaned around both sides 25 and 26 of the brush body 20 is sucked into the suction port 22 through the first and second suction passages 23 and 24 together with the air. The first and second suction passages 23 and 24 are formed in a U-shape having a flat lower surface on the lower surface of the brush body 20, and one end thereof is opened to the side surfaces 25 and 26 of the brush body head 21. , The other end is opened to the suction port 22. In addition, the first and second suction passages 23 and 24 are inclined upwardly toward the suction port 22, as shown in FIG.

The plurality of hair removing members 30 are installed in parallel with both sidewalls 23a and 24a of the first and second suction passages 23 and 24 inside the first and second suction passages 23 and 24. At this time, the hair removal member 30 is preferably installed at regular intervals in the substantially center of the first and second suction passages (23, 24). The length L of the whisk 30 is determined so that its tip 30a can be brought into contact with the surface to be cleaned. That is, the plurality of hair removing members 30 have different lengths L, as shown in FIG. 4, corresponding to the inclination angles β of the first and second suction passages 23 and 24. Therefore, the hair removal member 31 close to the suction port 22 is the largest, and the length decreases toward the inlets 23b and 24b of the first and second suction passages 23 and 24. That is, the length of the whisk member 32 close to the inlets 23b, 24b of the first and second suction passages of the plurality of whisk members 30 is the shortest. At this time, the plurality of hair removing member 30 is preferably formed of an elastic material so as not to damage the surface to be cleaned while performing a function of removing dirt attached to the surface to be cleaned. Thus, when the hair removal member 30 has elasticity, it is particularly effective because it can give an effect of brushing the surface to be cleaned when cleaning the soft surface to be cleaned such as a carpet. As the elastic material, it is preferable to use a plastic having elasticity equivalent to urethane, silicone and the like having a certain elasticity.

And each hair removal member 30 is preferably formed in a conical shape that the diameter is smaller toward the surface to be cleaned from the lower surface of the brush body head 21. Thus, when the hair removal member 30 is made into a cone, dirt removal of the to-be-cleaned surface by the hair removal member 30 can be made more effective. At this time, the plurality of hair members 30 may be formed of cones of different sizes, respectively, but it is preferable to make the plurality of hair members 30 have a predetermined standard. That is, the plurality of hair scraping members 30 are formed to have the same conical angle α (see FIG. 7). Alternatively, the size of the cone may be determined such that the diameters (D, see FIG. 7) of the bottom ends of the plurality of hair cutting members 30 and the diameters (d, see FIG. 7) of the tips are the same.

In addition, the front end (30a ') of the hair removal member 30 can be treated as a curved surface as shown in Figure 5, to provide a hair removal hole 40 having a width larger than the diameter of the front end of the hair removal member (30) It is preferable. Thus, when the hair removal hole 40 is installed, the contact area between the hair removal member 30 and the surface to be cleaned can be made larger, and the dirt attached to the surface to be cleaned can be more easily removed. At this time, the hair hole 40 is formed into a sphere (sphere), the diameter (W) is preferably set to be smaller than the diameter (D) of the bottom of the hair member 30 and larger than the tip diameter (d) of the hair member. Do.

In addition, the plurality of hair removal member 30 is installed to be inclined so that the front end toward the suction port 22 as shown in FIG. When the plurality of hair removal members 30 are inclined as described above, dirt, such as hair, hair, and yarn sucked through the first and second suction passages 23 and 24 may be reduced. have. That is, when the plurality of hair removing members 30 are inclined with respect to the surface to be cleaned, dirt is sucked into the plurality of hair removing members 30 as compared to the case where the hair removing member 30 is perpendicular to the surface to be cleaned. The phenomenon that the flow paths 23 and 24 are blocked can be reduced. At this time, it is preferable that the plurality of hair removing members 30 are inclined such that the installation angle θ is inclined at 40 degrees to 50 degrees with respect to the bottom surfaces of the first and second suction passages 23 and 24.

In addition, the plurality of hair removing members 30 are integrally formed with respect to the brush body 20 as shown in FIG. 4, or each of the plurality of hair removing members 30 is first and second suction of the brush body 20. It is configured to attach to the inside of the flow path (23, 24) by a fastening member (not shown).

However, in order to facilitate the assembly and manufacture of the plurality of hair removing members, it is preferable to mold the plurality of hair removing members into the hair removing member unit 50 in the form of one sub-assembly as shown in FIG. 6. Referring to FIG. 6, the hair removing member unit 50 is formed of a base 51 and a plurality of hair removing members 52. The plurality of hair removing members 52 are integrally formed with the base 51. However, it is obvious that the plurality of hair removing members 52 may be separately formed and then assembled to the base 51. In addition, since the shape of the some hair removal member 52 is the same as that of the some hair removal member 30 of the above-mentioned embodiment, detailed description is abbreviate | omitted.

At this time, the first and second suction passages 23 and 24 of the brush body 21 are provided with first and second unit assembly grooves 53 and 54 to which the hair removing member unit 50 is assembled, respectively. Accordingly, the plurality of hair removing members 52 can be assembled to the brush body head 21 only by assembling the hair removing member unit 50 to the first and second unit assembly grooves 53 and 54.

The cover 12 is assembled on top of the brush body head 21 for aesthetics of the brush assembly 10.

The pair of wheels 15 are installed on the legs 29 of the brush body 20 so that the brush assembly 10 can move smoothly.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation and action of the brush assembly 10 of the vacuum cleaner according to the present invention.

When the vacuum cleaner (not shown) is operated, suction force is generated by the vacuum generator (not shown) of the vacuum cleaner main body (not shown). This suction force acts as the suction port 22 of the brush body 20 through the extension pipe 90.

When the suction force acts on the suction port 22 of the brush body 20, the air containing dirt is sucked from both sides 25 and 26 of the brush body 20 as shown by arrows B and C shown in FIG. 4. Will move toward). At this time, the dirt-containing air sucked into both sides 25 and 26 of the brush body 20 is moved to the suction port 22 through the first and second suction passages 23 and 24. Then, the dirt-containing air to be sucked can obtain the effect of dispersing the flow path by the plurality of whistle member (30). Therefore, it is possible to reduce the noise generated when the dirt-containing air sucked from both sides in the suction port 22 directly collides.

In addition, since the plurality of dusting members 30 are inclined with respect to the surface to be cleaned as shown in FIG. 4, dirts sucked with air are hardly caught by the plurality of dusting members 30.

In addition, when the user cleans the brush assembly 20 while moving back and forth, if there is dirt attached to the surface to be cleaned, the dirt attached to the surface to be cleaned by the pore 40 formed on the tip of the plurality of hair removal members 30. This can be removed effectively. For example, when moving the brush assembly 20 forward, as shown in FIG. 7, a plurality of dirts 17 are attached to the surface to be cleaned 16 with a force that does not fall by suction force. Some of the hair removal members 30 are caught in the dirt 17. At this time, when the user moves forward to the brush assembly 10, the dust member 30 caught in the dirt 17 is bent backward. Then, the dirt 17 attached to the surface to be cleaned 16 is subjected to the force by the hair removal hole 40 of the hair removal member 30. As the brush assembly 10 moves further forward, the dirt 17 is separated from the surface to be cleaned 16 by the elastic force of the hair removing member 30. If the dirt 17 of the surface to be cleaned 16 is not removed only by advancing the brush assembly 10, the user can remove the dirt 17 by backing the brush assembly 10 again.

In addition, if it is fixed to the surface to be cleaned 16, not the dirt, caught on the hair hole 40 of the hair removal member 30, the hair removal member 30 is bent over the other object in the bent state to be cleaned 16 It will not damage.

As such, the dirt removed by the plurality of hair removing members 30 is sucked into the suction port 22 through the first and second suction passages 23 and 24. The dirt and air sucked into the inlet 22 move toward the extension pipe 90 through the dirt passage (not shown) of the leg 29 of the brush body 10. Then, the dirt-containing air is sucked into the vacuum cleaner body (not shown) through the extension pipe 90. The air contained in the dirt-containing air sucked into the vacuum cleaner body is separated / collected by a dust collector (not shown) and only the clean air is discharged to the outside of the vacuum cleaner.

8 shows yet another embodiment of a brush assembly of a vacuum cleaner according to the invention. In the brush assembly 80 of the vacuum cleaner according to the embodiment of FIG. 8, the bottom surfaces of the first and second suction passages 82 and 83 of the brush body 81 are substantially parallel to the surface to be cleaned. Therefore, the lengths of the plurality of hair removing members 84 are almost the same. Except that the length of the plurality of hair removing member 84 is the same as the brush assembly 10 of the vacuum cleaner according to the above-described embodiment, detailed description thereof will be omitted.

As described above, according to the brush assembly of the vacuum cleaner according to the present invention, since the dirt suction air sucked into the suction flow path is dispersed by a plurality of hair removing members, noise generated by the air sucked into the suction port during cleaning can be reduced. .

In addition, according to the brush assembly of the vacuum cleaner according to the present invention, since the plurality of hair removing members removes the dirt attached to the surface to be cleaned, the dirt attached to the surface to be cleaned can be removed and sucked.

In addition, in the brush assembly of the vacuum cleaner according to the present invention, a plurality of hair removal members are inclined, so that dirt such as hair is less likely to be caught.

In addition, the brush assembly of the vacuum cleaner according to the present invention can prevent the cleaning surface from being damaged by the hair removing member because the plurality of hair removing members are made of an elastic material.

The present invention is not limited to the specific embodiments described above, but can be performed by a person skilled in the art to which the present invention pertains without departing from the spirit of the present invention described in the claims below. Substitutions, additions, deletions, and alterations fall within the scope of the claims.
