The present invention relates to a vacuum cleaner which filters the cleaning material in the intake air twice in a cyclone manner to improve the cleaning performance and facilitate the discharge of the collected cleaning material.

In general, a vacuum cleaner generates a suction force of a vacuum, sucks air, passes various filters, and filters dust in the air to clean the room.

Such vacuum cleaners can be divided into cylinder type, upright type, hand type, etc. according to the usage and moving method. The floor type is mainly used for cleaning dust, such as dust, for home use. It is easy to clean the floor of the back, and the hand type is easy to clean the small area such as the stairs and the desk.

In addition, the vacuum cleaner can be divided into filter type and cyclone type according to the method of filtering the cleaning material such as dust and hair from the intake air, and the filter type passes the air containing the cleaning material through a kind of cloth bag. While the dust bag needs to be replaced periodically because it filters, the cyclone type rotates the suction air containing the cleaning material so that the cleaning material contained in the suction air falls to the floor by its own weight while descending. The dust bag is not needed and has been applied recently.

In addition, the cyclone type vacuum cleaner was developed to improve cleaning performance by allowing the cleaning material to be filtered twice while passing through the inner / outer cyclone.

1A and 1B are a perspective view and a side cross-sectional view showing an example of a dust collector for a conventional vacuum cleaner.

Looking at an example of a conventional double cyclone for a vacuum cleaner with reference to Figures 1a and 1b, a conical inner cyclone (4) is installed inside the cylindrical outer cyclone (2), the inner cyclone (4) ) The outer peripheral surface is provided with a mesh (6) for filtering the cleaning material from the air rising from the bottom surface of the outer cyclone (2) and the scattering prevention portion (6a) to prevent the cleaning material from being scattered again, the inner An extension part 8 is provided below the cyclone 4 so as to be in contact with the inner side of the outer cyclone 2. As a result, the outer dust container 9a is disposed between the upper side of the extension part 8 and the inner side of the outer cyclone 2. ) Is formed and an inner dust container 9b is formed between the lower side of the extension 8 and the bottom surface of the outer cyclone 2.

At this time, a pair of suction passages 2a are formed on the inner upper side surface of the outer cyclone 2 so that the suction air can be introduced, and at the same time, the upper surface of the outer cyclone 2 is discharged so as to discharge the filtered air. While the flow path 2b is formed, both chambers 4a are formed on the outer upper surface of the inner cyclone 4 so that air passing through the mesh 6 can be introduced therein.

Therefore, when the suction force is generated, the suction air containing the cleaning material descends while rotating along the inner surface of the outer cyclone 2 through the suction flow path 2a, and the cleaning material in the suction air is dropped by its own weight. After accumulated in the outer dust container (9a), the air is first filtered by the cleaning material in the outer cyclone (2) rises, and even if the cleaning material is scattered again with the air hits the scattering prevention portion (6a) to fall again .

Thereafter, the air that has passed through the outer cyclone 2 descends while rotating along the inner surface of the inner cyclone 4 through the chamber 4a, and the remaining cleaning material in the air is dropped by its own weight so that the inner dust box ( 9b), the air secondary to the cleaning material filtered in the inner cyclone (4) is raised to be discharged along the discharge passage (2b).

Of course, the cleaning material filtered from the outer cyclone 2 and the inner cyclone 4 is accumulated in the outer dust container 9a and the inner dust container 9b, and the lower part of the outer cyclone 2 may be disassembled and cleaned. The material may be discarded or may be separately configured to discharge the cleaning material downward.

However, the double cyclone dust collector as described above has an inner cyclone 4 installed inside the outer cyclone 2, and an extension part 8 is formed below the inner cyclone 4 so that the outer dust bin is formed. (9a) and the inner dust container (9b) is formed to be divided, so the volume of each dust container (9a, 9b) can be limited, which is cumbersome to remove the cleaning material frequently, the external cyclone (2) to empty the cleaning material After separating the inner cyclone (4) from the), the outer cyclone (2) must be turned upside down, there is a problem that it is difficult to empty the cleaning material.

In addition, the double cyclone dust collector as described above is configured to increase the height of the outer cyclone 2 in order to increase the volume of each dust container 9a, 9b as a method for further improving the cleaning performance. In this case, however, there is a problem in that it is difficult to be incorporated into the vacuum cleaner as the overall product becomes higher.

Figure 2 is a partial cutaway perspective view showing another example of a conventional dust collector for a vacuum cleaner.

Looking at another example of a conventional double cyclone for a vacuum cleaner with reference to Figure 2, a cylindrical inner cyclone 12 smaller than the main body 11 is formed in the center of the cylindrical body 11, the main body 11 and A plurality of conical outer cyclones 14 are arranged at regular intervals in the circumferential direction so as to abut between the inner cyclones 12, and the mesh 16 is installed at the center of the inner cyclone 12 so as to hang at the same time. 16) At the lower end, a shatterproof portion 18 is formed which is extended to be inclined downward to prevent the cleaning material filtered from the inner cyclone 12 from rising with the rising airflow.

At this time, the inlet pipe 12a through which the suction air flows into the inner upper side of the inner cyclone 12 is formed to penetrate the main body 11 and the inner cyclone 12, and the outer cyclones 14 An outflow pipe (not shown) is formed on the upper side of the main body 11 to allow the air to pass out, and an inlet (not shown) and dust are introduced into the upper and lower surfaces of the outer cyclone 14, respectively. A dust outlet 14a through which the cleaning material is discharged is formed, and at the same time, an outlet 14b through which the cleaning material is filtered is discharged.

Of course, the air filtered by the cleaning material while passing through the inner cyclone 12 is introduced into each upper side of the outer cyclones 14, and the air filtered by the cleaning material while passing through the outer cyclones 14 is. Flow passages communicating with each other are formed to be discharged to the outside.

In addition, an inner cleaning bin 19a is formed on the bottom surface of the inner cyclone 12 to accumulate the cleaning material filtered from the inner cyclone 12, and an outer surface of the bottom surface between the main body 11 and the inner cyclone 12 is formed. An external dust bin 19b in which the cleaning material filtered out of the cyclones 14 is accumulated is formed.

Therefore, when the suction force is generated, the suction air containing the cleaning material descends while rotating along the inner surface of the inner cyclone 12 through the inlet pipe 12a, and the cleaning material in the suction air falls by its own weight. After being accumulated in the inner dust container 19a, the air primarily filtered out of the cleaning material in the inner cyclone 12 rises.

At this time, even if the cleaning material accumulated in the inner dust container 19a with the air rising from the bottom surface of the inner cyclone 12 rises again, it is hit by the scattering prevention unit 18 so that the cleaning material falls back on the inner dust container 19a. do.

Thereafter, the air passing through the inner cyclone 12 descends while rotating along the inner surface of each outer cyclone 14 through each inlet of the outer cyclones 14, and the remaining cleaning material in the air is its own weight. By falling through the dust outlet 14a of each outer cyclone to be accumulated in the outer dust bin (19b), the air secondary to the cleaning material filtered in the outer cyclones (14) rises to each outlet of the outer cyclones And discharge along 14b and outlet.

Of course, the cleaning material filtered out of the inner cyclone 12 and the outer cyclones 14 is accumulated in the inner dust container 19a and the outer dust container 19b, and the lower part of the main body 11 may be decomposed to clean the cleaning material. This may be discarded, or may be configured to separately discharge the cleaning material.

However, such a double cyclone dust collector has a relatively large cleaning material collected in the inner dust container 19a while the intake air passes through the inner cyclone 12, and then passes through the mesh 16 installed in the vertical direction. Relatively small cleaning material is collected in the outer dust container 19b while passing through each outer cyclone 14.

Therefore, since the inner dust container 19a is covered by the outer dust container 19b, it is difficult not only to empty cleaning materials such as hair and dust collected in the inner dust container 19a at an appropriate time, but also to collect the relatively small cleaning material. As the dust bin 19b is formed larger than the internal dust bin 19a where a relatively large cleaning material is collected, the space utilization decreases. Furthermore, the mesh 16 has a smaller diameter as it is installed inside the inner dust bin 19a. It is designed so that the hair 16 is easily caught on the mesh 16, and the mesh 16 is also covered by the external dust container 19a and thus cannot be easily observed. There is a problem that acts to lower the suction performance.

In addition, in order to discard the cleaning material, the entire dust collector is moved to a place where it is to be discarded. Then, the bottom surface of the inner dust container 19a and the outer dust container 19b is blocked, and the lid is opened and the cleaning material must be discharged. There is a problem that is difficult to discharge the material.

It is installed to engage the inner diameter of the cyclone body 113 or the cyclone cover 114 to divide between the inlet pipe 111 and the outlet pipe 112 of (110).

At this time, the inner circumferential end of the first flow passage compartment 131 comes into contact with the bottom surface of the outer end of the cyclone unit 121, and the inlet 121a of the cyclone unit 121 is the first flow passage compartment 131. It is configured to extend from the inner circumferential end of, and is guided by the inner circumferential end of the first flow passage compartment 131 flows into the inlet (121a) of the cyclone unit 121.

Looking at the operating state of the dust collector for a vacuum cleaner configured as described above, as follows.

First, when the suction force is generated, the air sucked through the inlet pipe 111 is moved downward in the helical direction as it is directed toward the inner wall of the cyclone body 113, the relatively heavy cleaning material in the cyclone flow Falling by to accumulate the space between the cyclone body 113 and the dust separator 143 in the primary dust container 141.

At this time, even if the cleaning material accumulated in the primary dust container 141 is re-flyed by the rising airflow in the cyclone body 113 inside the cyclone body 113, it is blocked by the dust separating plate 143 and sinks again. Only the first filtered air rises in the vertical direction, and then the cleaning material such as hair is filtered again while passing through the mesh unit 133.

Next, the air passing through the mesh unit 133 is guided to the inlet 121a of the cyclone unit 121 by the first flow passage compartment 131 and through the inlet 121a of the cyclone unit 121. The introduced air moves to the center in the helical direction along the inner surface of the cyclone unit 121, and the cleaning material passes through the dust guide portion 122 and the secondary dust container through the dust outlet 121b of the cyclone unit 121. 142 collected in the cleaning material is secondarily filtered to move outwardly from the inside of the cyclone unit 121 to exit through the outlet 121c of the cyclone unit 121.

Next, the air escaped to the outlet 121c of the cyclone unit 121 is not mixed with the flow of the cyclone body 113 by the second flow passage compartment 132, and the air flows to the second flow passage compartment 132. Pass through the space between the clone cover 114, and completely out through the outlet pipe (112).

Through this process, the cleaning performance can be further improved as the cleaning material is filtered by the two cyclone method, and when the cleaning material is collected in the dust container 140, the dust container 140 is disposed in the vertical cyclone unit ( 110) and from the horizontal cyclone unit 120 to easily empty the cleaning material.

It is guided to the inlet port 221a of the cyclone unit 221 by the lower end of the 1 euro compartment 231.

Similarly, the air introduced into the cyclone units 221 is secondary to the cleaning material separated by the cyclone flow, and the cleaning material is disposed through the dust guide portion 221a through the dust outlet 221a of the cyclone units. 222 and the secondary dust container 242, the air secondary to the cleaning material is filtered out through the outlet 221c of the cyclone unit 221.

Next, the air exiting to the outlet 221c of the cyclone unit 221 is not mixed with the flow of the cyclone body 213 by the first and second euro compartments 231 and 232, and the first and second euro compartments ( 231, 232 and the cyclone cover 214 is passed through the outlet pipe 212 to the outside completely through the space, the cleaning material collected in the dust container 240, the dust container 240 is a vertical cyclone portion 210 and Separate from the horizontal cyclone portion 220 can be easily emptied.

In the above, the present invention has been described in detail by way of examples based on the embodiments of the present invention and the accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.

The vacuum cleaner according to the present invention constituted as described above is cleaned in two cyclones because the cleaning material is first filtered while the suction air passes through the vertical cyclone part, and then the cleaning material is secondly filtered while passing the horizontal cyclone part. By filtering the material has the advantage of further improving the cleaning performance.

In addition, the present invention increases the position of the inlet pipe and at the same time change the shape of the flow path compartment to generate the cyclone flow of the first suction air from the cyclone cover and the cyclone body to generate a space where cyclone flow is generated in a limited space Increasing it reduces the height of the product and at the same time improves the cleaning performance.

In addition, since the present invention is detachably installed in the vertical cyclone portion or the horizontal cyclone lower portion of the dust bin collecting the cleaning material can be separated only the dust bin, the cleaning material can be discharged can be easily discharged cleaning material There is an advantage.

In addition, since the present invention includes a dust container collecting the secondary filtered cleaning material inside the dust container in which the first filtered cleaning material is collected, the dust container in which the larger cleaning material is collected can be configured larger than the dust bin in which fine dust is collected. The space can be utilized, and the dust container collecting relatively large cleaning material can be observed from the outside, and the cleaning material can be discharged at the appropriate time, and the mesh part is installed inside the vertical cyclone connected to the dust box installed relatively outside. After removing the dust container, there is an advantage that can be more easily removed hair caught in the mesh portion from the bottom.
