The present invention relates to a vacuum cleaner and, more precisely, to the node of the vacuum cleaner, made with a suction channel, through which the contaminant particles from the surface being cleaned, are absorbed into the body of the vacuum cleaner.

Usually the vacuum cleaner sucks dust particles and debris from the surface being cleaned, due to the suction force created by the vacuum source located inside the housing of the vacuum cleaner. Sources of vacuum applied in the vacuum cleaners, well-known experts in the art, and their description is omitted for brevity.

The vacuum cleaner usually contains the body of the vacuum cleaner, in which is placed a vacuum source, such as an electric motor to create a suction force, an elongated channel for passage of fluid, a first end of which is connected to the vacuum cleaner housing, ensuring messages fluid with a vacuum source, a node with a suction channel connected to the second end of the elongated channel for passage of fluid, and the node with the suction channels comprises upper and lower housing, the first and second suction channels made in the lower body (for example, the application FR No. 2599236 And 47 L 9/02, 1987).

Figure 1 presents a perspective view from below normal node 2 with the suction channel according to the prior art.

As shown in figure 1, Uzes the suction channel includes an upper housing 10 and lower housing 11. The suction channel 14 are made in the lower housing 11 for suction contaminant particles from the surface being cleaned. The lower housing 11 are also made with channels 12 for particulate contaminants on its both opposite lateral direction of the sides of S, and therefore, particles can also be absorbed into the vacuum source from both sides S of node 2 with the suction channel through inlet channel 14.

However, the node 2 with the suction channel usually has only one channel for passage of a fluid medium, for transmitting power vacuum for suction of polluting particles. Accordingly, while the suction force at the center of the suction channel 14 is large, on both sides there's a relatively reduced suction power. In other words, the cleaning efficiency is high in the center of the suction channel 14, but the cleaning efficiency is reduced on the sides S of the suction channel 14. Cleaning efficiency is particularly low when cleaning a wide area.

An attempt was made to solve the problem of the prior art. For this purpose it was proposed to place the intake duct on both sides of the node to the suction channels. However, the presence of the suction channel on both sides of the node to the suction channels helps reduce the effectiveness of cleaning in C is ntre site with suction channels.

The present invention eliminates the above disadvantages and solves other problems associated with the conventional device.

The purpose of this invention is to provide an improved site with suction channels, which can provide higher efficiency of cleaning not only the parties but also in the Central zone, and the creation of a vacuum cleaner having an improved site with suction channels.

The above tasks and/or other characteristics of the present invention are achieved by creating a node with suction channels containing the upper and lower housing, the first and second suction channels formed in the lower body, at least one upper hole punched in the upper casing, which allows suction of external air through it due to the suction force acting from the side of the first and second suction channels, and at least one lower hole made in the lower body, where the lower hole is located between the first and second suction channels and communicated in fluid with the upper hole, so that air entering through the top hole is directed into the area between the first and second suction channels for the dispersion of dust from them. The effectiveness of cleaning in the center of the node to the suction channels increases Can be achieved also increased the efficiency of the vacuum cleaner not only on both sides, but also in the center of the node to the suction channels.

In accordance with one aspect of the present invention, the node with the suction channel has an upper casing and the lower casing and the first and second suction channels formed in the lower body. In addition, the lower case is made with the first and second channels for dust connected with the first and second suction channels, and with the lower holes, respectively, the first and second channels for dust. There are also upper hole formed in the upper housing and connected in fluid with the lower holes.

By design, such as those described above, outside air is sucked through the upper hole due to the suction force of the suction channels, and sucked air passes through the lower holes, scattering dust from the Central node to the suction channels. Diffuse dust is moved by the first and second channels for dust and absorbed by the first and second suction channels. As a result, the cleaning efficiency provided by the node to the suction channels, increases not only on both sides, but also in the center.

When the dust sucked through the suction channels, the dust is directed by the first and second channels for the passage of fluid made in the upper and lower housings, and, therefore, moves in to the STS cleaner. Element, closing the channels for the passage of fluid and forming the upper part of the first and second channels for the passage of fluid, preferably can be formed of a transparent material so that the user can observe the movement of the sucked air outside and, therefore, could be "exempt" from the inconvenience associated with the need to scan all channels cleaner, intended for the passage of fluid when the problem occurs in the channels of the node to the suction channels intended for the passage of fluid.

The above aspects and features of the present invention will become more apparent in the description of certain embodiments of the present invention with reference to the accompanying drawings, in which:

Some embodiments of the present invention is described below in more detail with reference to the accompanying drawings.

In the following description the same reference position in the drawings are used for the same elements even in different drawings. Components defined in the description such as a detailed construction and elements, are nothing but the components are presented in order to facilitate a comprehensive understanding of the invention. Thus, it is obvious that the present invention can be implemented without these specific objects. In addition, well-known functions or constructions are not described in detail because they would hinder the understanding of the invention because of the unnecessary details.

As shown in figure 2 and 3, the node 200 to the suction channels according to a variant implementation of the present invention includes upper housing 211, which forms the upper part of the node 200 to the suction channels, and the lower housing 222, which forms the lower part. The upper housing 211 includes an element 250, closing channels for the passage of fluid and communicating with the lower is obosom 222, and the upper closing element 212 located above the element 250, closing channels for passage of a fluid medium, and interacting with the lower housing 222.

One or more upper openings 213 punched in the upper closing element 212 so that there is a channel for the passage of air passing through the upper closing element 212, and provides for the suction of external air through it. The upper closing element 212 is additionally made with part 214 with a cutout formed with a configuration that matches the configuration of the element 250, closing channels for the passage of fluid, so that the element 250, closing channels for the passage for the fluid, may be open to influence from outside of the node 200 to the suction channels. Accordingly, the element 250, closing channels for the passage of fluid escapes through a portion 214 with a cutout. Despite the fact that there are two upper openings 213 depicted in the figures, which are made in the form of cracks, the term "hole" should be interpreted as including one or more holes of other shapes. For example, one or more oval, round, elliptical, square or rectangular holes can be punched instead of the two shown in the figures. Any one or more channels passing through ve is hni closing element 212, represent "holes". Alternatively, the closing element can be located on the top hole selective opening only during the suction of air.

As shown in figure 3, the channel 240 for dust made in the lower part of the lower housing 222 with a stepped configuration. The channel 240 to the dust separated by the protrusion 246 performed on the lower part of the lower housing 222 between the first channel 242 for dust, connected in operating position with the first suction channel 226 and the second channel 244 to dust connected in operating position with the second suction channel 228. The bottom two holes 235 in the first channel 242 for dust and the second channel 244 to dust respectively near the ledge 246. Alternative options for the implementation of the holes 235 are also oval or triangular holes. The lower holes 235 may be performed in many different places and with different configurations, provided that they are in operating position is connected with the first and second suction channels 226 and 228.

By design, such as those described above, the external air can pass through the upper openings 213 and sent to the bottom of the lower housing 222 through the bottom holes 235. As the suction of external air dust located between the first and second suction channels 226 and 228, Russ is foreseen and absorbed in the first and second suction channels 226 and 228, passing through the first and second channels 242 and 244 to dust. Due to this operation, the dust located on both sides S of the node 200 to the suction channels can be effectively cleaned, and the cleaning efficiency in the Central part also increases. As a result, the cleaner provides effective cleaning of even the wide area subjected to cleaning. The dashed arrows in figure 3 show the passage through which the air from the upper openings 213 passes through the first and second suction channels 226 and 227 through the lower holes 235. Two pairs located at a distance from each other wheels 239 is mounted on the front and rear sides of the lower part of the lower housing 222.

As shown in figure 2, the lower housing 222 has first and second channels 230 and 232 for the passage of fluid, connected by fluid with the first and second suction channels 226 and 228. More specifically, the first and second channels 230 and 232 for the passage of fluid represent a space formed in the lower housing 222 and limited bottom part 222 and the element 250, closing channels for the passage of fluid. Accordingly, a dust, scattered by the air emitted from the upper and lower holes 213 and 235, is directed by the first and second suction channels 226 and 228 to the first and second channels 230 and 232 for the passage of fluid and displaced is moved to the body 100 of the vacuum cleaner (figure 4). The lower housing 222 is made on its rear end with such lower support 224 to the coupling element for the extension of the pipe on which the lower side pivotally connected a connecting part 118 of the connecting element 116 for extension tube set can be rotated. In addition, the lower housing 222 is made based 234 element, closing the channels for the passage of fluid, while this support is attached element 250, closing channels for the passage of fluid.

Element 250, closing channels for the passage of fluid, takes essentially the configuration of an arc in a vertical section with respect to the displacement of the sucked air. Element 250, closing channels for the passage of fluid, preferably made of transparent plastic to allow visual inspection by the user. Accordingly, the user can timely to draw attention to problems such as clogging with dust channel for passage of fluid. Along the border of the element 250, closing channels for the passage of fluid, extends the flange 258, which presses the upper closing element 212 during the interaction of the upper closing element 212 with the lower housing 222.

The following describes the process of an Assembly 200 to the suction channels according to one variant of the westline of the present invention.

First pivotally connect the connecting portion 118 of the connecting element 116 to the extension pipe is inserted into the bottom support 224 to the coupling element for extension tubes, located at the rear end or rear side of the lower housing 222. Element 250, closing channels for passage of a fluid medium, installed on the installation part for the item, closing the channels for the passage of fluid, which is made on the lower housing 222. Further, when the fastening element 250, closing channels for the passage of the fluid to the lower housing 222 pivotally connect the connecting portion 118 of the connecting element 116 for extension tube set can be moved in upper and lower bearings 224 and 264 for the coupling element to the extension pipe. Then the upper closing element 212 is attached to the lower housing 222 and the element 250, closing channels for the passage of fluid. The node with the suction channels finally collected by fasteners 236, such as screws, screw in the appropriate mounting holes 238, which are made in the upper closing element 212 and the lower housing 222. In addition, the upper closing element 212 presses the flange 258 element 250, closing channels for the passage of fluid, so that the element 250, closing Cana is s for the passage of fluid, and bottom housing 222 can be connected to each other with provision for air.

Figure 4 is a perspective view of a vacuum cleaner according to one given as an example of a variant of implementation of the present invention.

As shown in figure 4, the vacuum cleaner according to one particular variant of implementation of the present invention includes a housing 100 of a vacuum cleaner having located therein a vacuum source, the node 200 to the suction channels, such as those described above and intended for sucking dust from the surface being cleaned, due to the power vacuum created by the vacuum source, and an elongated channel 110 for the passage of fluid extending from the node 200 to the suction channels for guiding the sucked dust to the body 100 of the vacuum cleaner. An elongated channel 110 for passage of a fluid medium includes a coupling element 116 for extension pipe having a hinge connected the connecting portion 118, which is connected with the node 200 to the suction channels with the possibility of displacement of the extension pipe 114 connected to the connecting element 116 for extension tubes, and suction hose 112 attached at one end to the extension tube 114 and the other end to the body 100 of the vacuum cleaner.

Figure 5 is a front view of the node 200 to the suction channels,such as those described above, in this work node to the suction channels according to one variant of implementation of the present invention will be described with reference to the figure.

The operation of the node 200 to the suction channels are described below with reference to figure 4 and 5.

Suction force created by the vacuum source located in the housing 100 of the vacuum cleaner, is transmitted to the host 200 to the suction channels through the suction hose 112, extension tube 114 and the coupling element 116 to the extension pipe. After this suction force is transmitted to the first and second suction channels 226 and 228 via the first and second channels 230 and 232 for the passage of fluid. Accordingly, as the transfer suction force of the dust from the surface being cleaned, absorbed by the first and second suction channels 226 and 228. Suction force is also transmitted to the first channel 242 for dust (figure 3) and the second channel 244 to dust (figure 3) and to the lower holes 235. Then, the suction force is transmitted through space, tightly restricted to the upper closing element 212 and the lower housing 222, and is transmitted to the lower holes 235. Dust located between the first and second suction channels 226 and 228, is scattered and absorbed due to the suction force to the first and second channels 242 and 244 for dust (figure 3) in the first and second suction channels 226 and 228. The dust is, sucked in the first and second suction channels 226 and 228, are sent via first and second channels 230 and 232 for the passage of fluid and is moved to the connecting element 116 to the extension tube, the extension tube 114, the suction hose 112 and into the body 100 of the vacuum cleaner.

To a person skilled in the art it is obvious that the node 200 to the suction channels, described above, will provide superior cleaning. Similarly, the vacuum cleaner having such a node to the suction channels, will provide superior cleaning. Due to the outdoor air suction holes formed in the upper casing, and through the lower holes made in the lower body, the dust located between the first and second suction channels can be dispersed and removed. As a result, the cleaning efficiency in the Central part of the site to the suction channels can be increased. As a result, the cleaning efficiency even wide area may be increased.

In addition, since the element 250, closing channels for the passage of fluid, is made of a transparent material, the user immediately draws attention to the problem such as clogging with dust channel for passage of fluid outside. Therefore, the user is spared the inconvenience associated with the need to validate the entire channel cleaner designed for the of rachada fluid medium, when there is a blockage in the passage of the fluid in the node 200 to the suction channels.

The above variant of implementation and benefits are given merely as examples, and they should not be construed as limiting the present invention. This idea can easily be applied to other types of devices.
