The technical field

The present invention relates to the cyclone traps, and more particularly to a dual cyclone the cyclone, with many of cyclones connected with each other. Despite the fact that the application of the cyclone collector of the present invention is not limited to a vacuum cleaner for vacuum cleaner this the cyclone is particularly suitable.

Prior art

The cyclone collects dust and dirt (hereinafter referred to as collectively as dust) from the air using a cyclone. The cyclone has wide application and is applicable also to the vacuum cleaner as domestic use.

Currently, to improve capacity to collect dust used double the cyclone, with many of cyclone traps connected with each other. That is double the cyclone is provided with upper flow cyclone for drawing air containing dust and the like (hereinafter referred to as "polluted air"), and collecting relatively large dust particles and lower flow cyclone connected to the upper flow cyclone for collecting relatively small dust particles. In General double the cyclone is provided with a single upper stream in the cyclone and one lower flow cyclone. Lower popochku cyclone can have a number of small cyclones (hereinafter referred to as "mnogochislennyi trap"). An example of such mnogochislennogo trap is the trap described in the executed utility model Japan No. S5214775.

With reference to figure 1 will be described mnogochislennyi the trap of the prior art.

Mnogochislennyi the trap of the prior art equipped with a cyclone 1 (hereinafter referred to as "primary cyclone") to pull in outdoor air pollution and collecting relatively large dust particles, and the cyclone 3 (hereinafter referred to as "secondary cyclone"), connected to the primary cyclone 1 for collecting relatively small dust particles. The secondary cyclone 3 in mnogochislennoi design is a group of small cyclones.

Hereinafter it will be described in detail.

The secondary cyclone 3, having a number of small cyclones, installed on the outer circumference of the primary cyclone 1. The primary cyclone 1 has a first inlet 11 in the upper section of the first housing 12 of the primary cyclone 1 to pull in polluted air in the direction of the tangent and the first issue 14 essentially in the Central part of the primary cyclone 1 to release the initially filtered air (hereinafter referred to as "partially polluted air") in the secondary cyclone 3. In the General case, the first issue 14 has a cylindrical shape with an open bottom part 14b and has no holes in the top. In some the older cases in the open lower portion 14b sets the filter 16.

At the same time, the secondary cyclone 3 has a number of small cyclones that are installed on the outer circumference of the primary cyclone 1. Naturally, each of the secondary cyclones 3 also has an inlet (not shown) and release 34 (hereinafter referred to as "the second "start" and "second edition"). In the General case, between the primary cyclone 1 and the secondary cyclone 3 includes a damping chamber 56 formed therein. Through the damping chamber 56, the air is introduced into the secondary cyclone 3 of the primary cyclone 1. On the secondary cyclone 3 has a chamber 52 of the release associated with the second editions of 34 many of the secondary cyclones 3, to release the air with the dust collection which thereby is completed (hereinafter referred to as "clean air"), through the discharge tube 54 and through the chamber 52 of the release.

Next will be described the operation mnogochislennogo trap of the prior art.

At the beginning mnogochislennogo the collector to the propulsion means of creating a retracting force, such as a suction fan (not shown) of the vacuum cleaner, the polluted outside air is introduced into the primary cyclone 1 through the first inlet 11 of the primary cyclone 1. In this case, the contaminated air is drawn in the direction of the tangent and twists along the inner wall of the first housing 12 of the primary cyclone 1, and when this is ill is separated from the air by centrifugal force.

In this case, relatively large and heavy dust particles collected in the lower portion of the primary cyclone 1 and the small particles of dust are not going inward and twisting in the primary cyclone 1 rise and are produced through the first issue 14.

Meanwhile, partially polluted air is discharged from the primary cyclone 1 and is introduced into the secondary cyclone 3 through the second inlet (not shown). Ultimately, clean air with a small dust particles separated in the secondary cyclone 3 again comes out of the trap through the second issue 34, the exhaust chamber 52 and the outlet pipe 54.

Disclosure of inventions

Technical task

However mnogochislennyi the trap of the prior art has the following disadvantages.

The abrupt change of direction of the air flow from the primary cyclone through the first issue before entering into the secondary cyclone leads to pressure loss and reduces the efficiency of dust collection, and also causes the noise.

Technical solution

Accordingly, the present invention is directed to the creation of such a cyclone trap, which would largely eliminate one or more problems associated with the deficiencies and limitations of the prior art.

The present invention is to create a cyclone trap, which can be the t to improve the efficiency of dust collection.

Another objective of the present invention is to create a cyclone trap, which can reduce the noise.

To achieve these objectives and other advantages and in accordance with the purpose of the invention as implemented and described here, the cyclone has a primary cyclone having a first inlet for retracting the outdoor air and the first release to air release, secondary cyclone connected to the primary cyclone, and guide the thread means on the first release to prevent abrupt changes in flow direction of air discharged from the first release.

Preferably, the release includes a passing area having a passage and a closed area under a reduced area, and closed area is closed.

At the same time, it is preferable that the guiding thread means prevented a sharp turn when passing between the first edition of the primary cyclone and the inlet to the secondary cyclone. For example, a guiding thread means directs the air flow essentially in a perpendicular direction.

At the same time, it is preferable that guide the flow of the tool upper portion that extends farther from the first issue. For example, guiding the flow of the tool may have a tapered shape or a hemispherical shape.

Guiding the flow of the medium which in addition includes an additional element, going down to education of the passage. Preferably, the additional element has a given curvature.

Positive results

Accordingly, the present invention allows to increase the dust collecting efficiency and suction performance and reduce noise.

Brief description of drawings

The accompanying drawings are included to provide a better understanding of the invention and constitute part of this application, indicate the option(s) for carrying out the invention and together with the description serve to explain the principles of the invention. In the drawings shows

Figure 1 is a longitudinal section of a cyclone collector of the prior art;

Figure 2 is a longitudinal section of a cyclone collector in accordance with a preferred variant of the present invention;

3 and 4 are views in perspective of the sending thread means of figure 2; and

5 is a bottom view of a variant of directing the flow of funds figure 2.

The best option of carrying out the invention

Further detail preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. On the drawings to designate identical or similar parts are used the same reference position.

The cyclone in accordance with the preferred option done by the means of the present invention is described with reference to Figure 2.

The cyclone in figure 2, as in the prior art, includes a primary cyclone 1 and the secondary cyclone 3, connected to the primary cyclone 1. However, in the present invention the design of the first issue 14 of the primary cyclone 1 is different from that of the prior art.

As described in the prior art to the present invention in General believed that the first issue 14 of the first cyclone 1 requires an open bottom and to avoid the holes in the upper plot. The reason for this is that dust using the principle of cyclone requires pulling the air down along the inner wall of the casing for separating dust and for movement up again, essentially along the Central axis to exit. Accordingly it was considered that the upper portion of the first release of 14 should not have holes. However, the study of the inventors unexpectedly showed that even if the upper portion of the first release 14 has a passage, such as a perforation 18, the dust collection can be carried out efficiently.

Further detailed description of the design of the first issue 14 of the primary cyclone 1 according to the present invention.

The first output comprises an area 14a of the passage with passage, and a closed section 14b under the section of the passage. Any form section of the passage is to pers is coming, if only air is able to pass through it. For example, section 14a of the passage may be a perforated area having a number of holes 18. The shape of the opening 18 need not necessarily be round, is appropriate any other form. For example, instead of a round hole suitable passage in the form of a slit. For convenience below as an example we consider the perforated portion 14a having a number of holes 18.

Preferably, the perforated portion 14a passed down and was essentially parallel to the first body 12 of the primary cyclone 1. The perforated portion 14a has a closed bottom portion with a closed section 14b. Although the form of the first issue 14 is not limited, it is preferable to form the first issue 14 was cylindrical.

In addition, in the present invention has a guiding thread, the tool 200 is installed on the first issue 14 to prevent an abrupt change of direction of air flow from release 14. That is, directing the flow means the flow of air from the first issue 14 goes smoothly.

Further guiding the flow of the tool 200 will be described in detail.

As described, a guiding thread, the tool 200 is used to supply air from the first issue 14 in the secondary cyclone 3 without abrupt changes in direction. Accordingly, guiding the flow of the medium is at 200 serves for the formation of a passage without abrupt changes in direction between the first release 14 and the secondary cyclone 3, and more specifically, the inlet to the secondary cyclone 3. Therefore, it is preferable that the guiding thread of the tool 200 would change accordingly, pursuant to placement of the first issue 14 of the primary cyclone and the inlet (not shown) in the secondary cyclone 3. As shown in figure 2, if the secondary cyclone 3 is located outside of the primary cyclone 1, that is, the first issue 14 of the primary cyclone 1 and the inlet to the secondary cyclone is located essentially perpendicularly relative to each other, the guiding thread of the tool 200 also has a shape that provides air flow essentially in a perpendicular direction. For example, as shown in figure 3 and 4, a guiding thread, the tool 200 may have a shape that widens as the distance from the first issue 14. That is, preferably, a guiding thread, the tool 200 would have the form of a body of rotation, for example the shape of a cone or a hemisphere.

At the same time an additional element 210 can be performed on the reverse side of the sending thread means 200 also held down for the formation of many passages. Preferably, the additional element 210 had given curvature, and more preferably, the curvature was formed in the direction of the flow.

Next will be described the operation of this mnogochislennogo trap.

When you begin Nagoricane trap outside contaminated air is drawn into the first casing 12 through the first inlet 11 of the primary cyclone 1. In this case, since the contaminated air is drawn in the direction of the tangent of the first housing 12, the contaminated air is subjected to some twisting force for separating relatively heavy and large dust particles. The separated dust particles are collected in the lower part of the first housing 12, while the air containing the fine particles of dust are not yet divided, that is partially polluted air is released through the first issue 14. Partially contaminated air released from the first cyclone 1 in the secondary cyclone 3 through the first issue 14 is drawn into the secondary housing 32 through the secondary inlet (not shown) so that small dust particles are collected in the secondary housing 32 and the clean air is discharged from the trap to the outside through the discharge tube 54 through a secondary issue 34 and the exhaust chamber 52.

Smooth air passage from the primary cyclone 1 in the secondary cyclone 3 through the first issue by directing the flow to the tool reduces pressure losses and reduce the noise.

Although the above describes an implementation option first edition 1 with a closed bottom, the present invention is not limited to this option. That is the same as in the previous prior art, the present invention is applicable to the variant in which the first release has a configuration with a closed side and an open n the sung part.

In addition, although the above describes an implementation option mnogochislennyi trap having a secondary cyclone with lots of small cyclones, the present invention is not limited to this. Thus, the present invention can also be applied to the total double the cyclone collector having two cyclones connected to one another, or to minociclina the trap with only one cyclone.

Moreover, the cyclone according to the present invention is applicable to a vacuum cleaner with a filter or direct the vacuum cleaner.

Specialists in the art it should be clear that within the framework of the present invention can be implemented in various modifications and variations, without departing from the essence and scope of the invention. Thus, it is expected that modifications and variations of the present invention is not beyond the scope of the attached claims and their equivalents.
