Description

Dust Box for Vacuum Cleaner {DUST CASE FOR VACUUM CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to a dust container for a vacuum cleaner, which is easily detachable.

In general, the vacuum cleaner includes a driving device for generating a suction force, and a filter provided in a flow path through which air introduced by the driving device passes and filters foreign substances in the air.

The filter is made of a material through which air passes and foreign matter does not pass. If the amount of foreign matter adsorbed on the filter is increased by more than a predetermined value, foreign matter accumulated in the filter blocks the flow path of the air and the suction power is weakened. .

Recently, a cyclone dust box has been developed so that the air flowing into the dust box does not pass directly through the filter, but the air introduced into the dust box flows through the filter after being flowed in a tornado shape inside the dust box.

This action causes foreign matter in the air to fall to the bottom surface of the dust container while air flows inside the dust container, so that foreign matters having a predetermined size or more are first collected.

As the first filtered air of the foreign matter larger than a predetermined size passes through the filter, fine dust is filtered and foreign matter in the air is collected into the dust container.

If this operation continues for a long time, foreign matters accumulate in the dust bin, which hinders the flow of air. Therefore, the dust bin should be separated from the vacuum cleaner to remove the accumulated foreign matter in the dust bin.

Since the vacuum cleaner dust container according to the prior art does not have a separate means for separating the dust container from the vacuum cleaner, there is a problem in that the separation operation of the dust container is not easy when the dust container is separated from the vacuum cleaner for discharging the foreign matter.

Therefore, there is a need for improvement.

The first guide pipe 50 is provided with a hole portion 54, the second guide pipe 70 is provided to partition the inside of the case 10 and the first guide pipe 50, the inlet hole 72 and And a filter 100 that flows along the inner wall of the second guide tube 70 and filters foreign matter in the air discharged through the discharge port 14a.

As a result, the air introduced into the case 10 through the inlet 12a is first introduced into the first guide tube 50 and the foreign matter is first filtered, and the second guide tube 70 is introduced into the second foreign matter. The filter is filtered, and foreign matter is filtered in the third direction while passing through the filter 100 and discharged to the outside of the case 10 through the discharge port 14a.

Here, the case 10 includes a main body 12 having a suction port 12a and a detachable connection to the main body 12, a discharge port 14a provided, and a housing part in which the filter 100 is accommodated ( A top plate 14 having a 14b) and a cover 16 connected to the main body 12 so as to be openable and closeable.

When cleaning the inside of the dust container by such a configuration, the cover 16 can be opened to remove the foreign matter accumulated in the main body 12, and the filter 100 stored in the top plate 14 can be taken out to clean the filter 100 or the like. It can be replaced.

In addition, the receiving portion 14b is provided with a through hole portion 14c through which air is introduced from the second guide tube 70, and is provided with a third guide tube 90 extending from the through hole portion 14c. Air flowing into the filter 100 from the inside of the tube 70 collides with the outer wall of the third guide tube 90 and flows downward, and then rises again from the lower end of the third guide tube 90 to filter 100. ) Flows to the side.

Due to the flow of air, foreign matter in the air falls downward, and only the air rises along the third guide tube 90, so that the effect of filtering the foreign matter is added.

The first guide pipe 70 has a funnel-shaped inclined surface 52, a passage hole 54 provided in the inclined surface 52, and a blocking portion provided in the inclined surface 52 corresponding to the inlet 12a ( 56).

Here, since the suction port 12a is formed at a position eccentric from the center of the main body 12, the air flowing through the suction port 12a flows in a whirlwind shape along the inner wall of the main body 12.

Since the through hole 54 is not formed in the blocking portion 56 corresponding to the inlet 12a, the air collided with the blocking portion 56 does not flow into the first guide tube 50, and the inclined surface 52 does not form the through hole 54. Along the bottom.

As the air flowing in the whirlwind shape along the inner wall of the main body 12 descends to the lower side of the main body 12 and ascends, foreign matter larger than a predetermined size falls on the bottom surface of the case 10, that is, the cover 16. Primary collection takes place.

As a result, the air inside the first guide tube 50 is introduced into the second guide tube 70 through the inlet hole 72, and a fan-shaped guide panel 77 is provided inside the inlet hole 72. Therefore, the air introduced into the second guide tube 70 flows in a tornado shape.

The foreign matter in the air flowing in this way flows downward along the inclined portion 74 and is collected into the compartment pipe 76 to form secondary collection of the foreign matter.

Since the inclined portion 74 is inserted into the compartment tube 76, a step is formed between the compartment tube 76 and the inclined portion 74 so that foreign matter collected in the compartment tube 76 is formed on the inner wall of the compartment tube 76. As the foreign matter is blocked by the inclined portion 76, even if raised while rotating in a whirlwind shape, it is possible to prevent foreign matter from flowing to the filter 100 side.

In addition, since the first guide pipe 50 and the second guide pipe 70 form a funnel by the inclined surface 52 and the inclined portion 74, a space between the main body 12 and the first guide pipe 50. Since the space between the main body 12 and the second guide tube 70 is widened, it is possible to suppress the foreign matter flowing along the inner wall of the main body 12 from contacting the first guide tube 50.

By this operation, foreign matter in the air can be prevented from flowing into the first guide pipe 50 without flowing to the lower side of the main body 12, so that the primary collection of the foreign matter can be effectively performed.

In addition, since the cover 16 is provided with a flow preventing panel 16a, the foreign matter dropped on the cover 16 is prevented from rotating along the inner wall of the main body 12, so that the foreign matter is raised while rotating along the inner wall of the main body 12. Since it is possible to prevent the foreign matter collected from flowing to the filter 100 side can be suppressed.

The first guide tube 50 is provided with a coupling portion 58 coupled to the top plate 14, and the second guide tube 70 is provided with a mounting portion 78 fastened to the coupling portion 58. (14) is integrally coupled.

Thus, after the first guide tube 50 and the second guide tube 70 are coupled to the top plate 14, the top plate 14 is assembled to the main body 12, so that the first guide tube 50 and the second guide tube 50 are combined. Installation of the pipe 70 can be completed, so that the dust container can be easily assembled.

In addition, since the direction holding part 80 is provided to allow the blocking part 56 to be mounted in a direction corresponding to the inlet 12a, the first guide pipe 50 and the second guide pipe 70 are provided only in a predetermined direction. It can be coupled to (12) to prevent the blocking portion 56 is arranged to be spaced apart from the inlet (12a).

The direction holding part 80 includes a first projection 81 provided in the engaging portion 58, a first groove portion 82 provided in the mounting portion 78 corresponding to the first projection 81, and a mounting portion 78. ), The second projection 83 provided in the top, the second groove portion 84 provided in the top plate 14 corresponding to the second projection 83, and the third projection 85 provided in the main body 12. And a third groove 86 provided in the top plate 14 corresponding to the third protrusion 85.

Thus, when the first guide tube 50 and the second guide tube 70 are coupled to each other by the first protrusion 81 and the first groove portion 82 in a predetermined direction, the second guide tube 70 and When the top plate 14 is coupled to each other by the second projection 83 and the second groove 84 in a predetermined direction, when the top plate 14 and the main body 12 when the third projection 85 And the third groove 86 are coupled in a predetermined direction.

The dust container for a vacuum cleaner configured as described above is provided with a handle 30 provided in the case 10, and a detachable portion 40 provided with the handle 30 and the vacuum cleaner to maintain the coupled state of the case 10. It includes.

Here, the handle 30 is inclined so that when the dust container is coupled to the vacuum cleaner, the handle 30 is easily inserted into the vacuum cleaner while being inserted into the vacuum cleaner, and thus the combined state of the dust container is maintained by the detachable part 40.

The top plate 14 of the case 10 is provided with a handle frame 20 for sealing the receiving portion 14b, the handle frame 20 is formed with a fixing portion 22 to which the handle 30 is coupled. .

In addition, since the inclined surface portion is formed in the fixing portion 22, the handle installed on the inclined surface portion is disposed to be inclined from the case 10 to form an inclination to facilitate the coupling of the dust container.

In addition, since the handle 30 is made of an elastic material, when the vacuum cleaner is coupled to the vacuum cleaner by the detachable part 40, the handle 30 can be easily deformed while deforming a predetermined amount, and the handle 30 is pulled out when the dust container is separated. This will make it easier to remove the dust bucket from the vacuum cleaner.

The detachable part 40 includes a locking protrusion 42 provided on the handle 30 and a locking jaw portion 44 provided on the vacuum cleaner corresponding to the locking protrusion 42.

Accordingly, when the dust container is inserted into the vacuum cleaner, the handle 30 is deformed by a predetermined amount and the locking protrusion 42 is inserted into the locking jaw portion 44. When the dust box is completely seated, the handle 30 is restored to its original state by restoring force. The restoring projection 42 is caught by the restraining jaw portion 44 while being restored to maintain the combined state of the dust container.

Looking at the operation of the vacuum cleaner dust container according to the present invention configured as described above are as follows.

First, when power is applied to the driving device of the vacuum cleaner, suction force is generated and air is introduced through the suction port 12a, so that the air flows in a toroidal shape along the inner wall of the main body 12, and then flows downward toward the lower side of the main body 12, and then again. As it rises, it flows into the first guide pipe 50 through the passage hole 54.

At this time, the air flowing through the inlet 12a flows in a vortex shape along the inner wall of the main body 12 by the eccentric inlet 12a, and the air flowing directly to the first guide tube 50 is blocked 56 ) And then flows downward, so that the air flowing into the main body 12 descends downward and then rises again.

By the air flow, foreign matters larger than a predetermined size fall to the cover 16 side, so that the first collection of the foreign matters is made.

Since the foreign matter dropped to the upper surface of the cover 16 is prevented from flowing in a tornado shape by the flow preventing panel 16a, it is possible to suppress the flow toward the filter 100 without flowing along the inner wall of the main body 12. .

The air introduced into the first guide tube 50 is introduced into the second guide tube 70 through the inlet hole 72, and is again in a tornado shape by the guide panel 77 provided in the inlet hole 72. And foreign matters in the air flowing along the inner wall of the second guide tube 70 are dropped into the compartment tube 76 along the inclined portion 74 to form secondary collection of the foreign matters.

In this way, the foreign matter collected into the compartment pipe 76 rises in a whirlwind shape along the inner wall of the compartment pipe 76 by the flow of air, and the end of the inclined portion 74 is inserted into the compartment pipe 76. As a step is formed, the partition pipe 76 can prevent the foreign substances from rising, thereby preventing the foreign substances from flowing to the filter 100 side.

As described above, the air introduced into the second guide tube 70 collides with the outer wall of the third guide tube 90 and descends downward, and then rises from the opened lower end of the third guide tube 90. It flows through the 3rd guide pipe 90 to the accommodating part 14b.

At this time, as the air descends, foreign matter in the air falls to the partition tube 76 to form a third collection of the foreign matter.

The air passing through the accommodating portion 14b passes through the filter 100 to perform fourth collection of foreign matter, and is discharged to the outside of the dust container through the discharge port 14a.

As described above, foreign matter collected by the first guide tube 50, the second guide tube 70, and the third guide tube 90 falls on the cover 16, the inclined portion 74, and the flow prevention. Since the foreign matter is prevented from rising to the filter 100 side by the panel 16a, the amount of the foreign matter accumulated in the filter 100 is not large until the foreign matter accumulated in the dust container reaches a limit value.

As a result, the foreign matters can be prevented from obstructing the flow of air until the accumulated amount of foreign matters reaches the limit value, thereby suppressing the weak suction force of the vacuum cleaner.

If the operation as described above is made for a long time, since the foreign matter accumulated in the dust container reaches the limit, the dust container should be separated from the vacuum cleaner to remove the foreign matter.

At this time, when the user pulls the handle 30 toward the case 10, the handle 30 is deformed by a predetermined amount and the locking protrusion 42 is separated from the locking jaw portion 44 so that the dust container can be easily taken out.

The dust container separated from the vacuum cleaner may open the cover 16 to discharge the foreign matter inside the main body 12, and when the handle frame 20 is removed from the top plate 14, the filter case 15 may be stored in the storage unit ( It is possible to clean or replace the filter 100 by separating from 14b).

After the dust box is cleaned, the dust box is inserted into the vacuum cleaner, and the handle 30 is deformed while the locking protrusion 42 is inserted into the locking jaw portion 44. When the dust box is completely seated, the handle ( While the 30 is restored to its original state, the locking protrusion 42 is caught by the locking jaw portion 44 to complete the coupling of the dust container.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and various modifications and equivalent other embodiments are possible to those skilled in the art. Will understand.

In addition, the vacuum cleaner dust box has been described as an example, but this is merely illustrative, and the dust box of the present invention may be used in other products than the vacuum cleaner.

Therefore, the true technical protection scope of the present invention will be defined by the claims below.
