Description

[0001] This application is a divisional application of a patent application with an application date of October 17, 2016, application number 201680059711.3, and invention name “Cyclone dust collection device and vacuum cleaner including the same”. Technical Field

[0002] The present disclosure relates to a cyclonic dust collector having improved usability and a vacuum cleaner including the same. Background Art

[0003] The vacuum cleaner is a device configured to perform cleaning by sucking air using a suction force generated by a fan and a motor and by filtering foreign matter included in the sucked air.

[0004] The vacuum cleaner includes a dust collecting unit in which foreign matter is filtered out through a predetermined filter portion, thereby filtering out the foreign matter from the sucked air. The filtering device that allows the foreign matter to be filtered out through the dust collecting unit includes a porous filter unit in which the foreign matter is forcibly filtered out while the air passes through the porous filter, and a cyclone-type dust collecting unit in which the foreign matter is filtered out while the air cyclones.

[0005] Cyclone dust collectors can be widely used in horizontal vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, etc.

[0006] The cyclone dust collector may include an inlet portion through which air is introduced and an outlet portion through which air is discharged to the outside. Dust in the air introduced through the inlet portion may be filtered out, and the filtered air may be discharged to the outside through the outlet portion.

[0007] The outlet portion may include a grille portion. Since the air through hole is formed in the grille portion, dust particles of a predetermined size or larger cannot be discharged through the outlet portion. Large pieces of dust, hair, etc. may be entangled around the outer peripheral surface of the grille portion by the air rotating in the cyclone dust collector. When the air through hole is clogged with dust adhering to the outer peripheral surface of the grille portion, the suction force of the vacuum cleaner is reduced. In addition, there is an inconvenience in that the user removes the dust adhering to the outer peripheral surface of the grille portion with his or her own hands. Summary of the invention

[0008] Technical issues

[0009] The present disclosure is directed to a cyclone dust collector capable of preventing reduction in suction force and a vacuum cleaner having the same.

The air purified by the fine filter 68 may be discharged to the outside of the cyclone dust collector 61 via the outlet 613.

[0063] The grille assembly 67 may be detachably mounted on the housing 610. When the grille assembly 67 is separated from the housing 610, dust adhered to the surface of the grille portion 670 may be interfered with by the cleaning portion 618.

[0064] The cleaning portion 618 may be provided to protrude from the inner surface of the lower cover 610a, and the lower cover 610a forms an opening 612b (see FIG. 6A ) through which the grill assembly 67 is inserted. Figure 4 ). The cleaning portion 618 may be provided to extend in the same direction as the direction in which the grille portion 670 extends. When the grille assembly 67 is separated from the housing 610, the grille assembly 67 may be provided to contact the surface of the grille portion 670. A plurality of cleaning portions 618 may be provided. In addition, the lower cover 610a and the cleaning portion 618 may be integrally injection molded.

[0065] The shape of the cleaning portion 618 is not limited to the above shape. For example, the surface of the grille portion 670 may be provided to be interfered with by the inner surface of the lower cover 610a, and the lower cover 610a forms the opening 612b through which the grille assembly 67 is inserted. Here, the cleaning portion 618 may be the inner surface of the lower cover 610a.

[0066] The user can separate the grille assembly 67 from the housing 610, and when the grille assembly 67 is separated from the housing 610, the dust adhering to the surface of the grille portion 670 can be interfered with by the cleaning portion 618 and removed from the grille portion 670. Since the user does not remove the dust adhering to the surface of the grille portion 670 by himself, the cyclone dust collector 61 is easy to clean and sanitary.

[0067] Hereinafter, the operation of the vacuum cleaner according to one embodiment of the present disclosure will be described.

[0068] When the fan motor (not shown) of the main body 10 is driven, the air around the target surface can be sucked by the suction force of the fan motor (not shown) through the suction unit 62. The sucked air can sequentially pass through the extension pipe 63, the handle pipe 64 and the flexible hose 66, and can be introduced into the cyclone dust collector 61 installed in the main body 60.

[0069] The air introduced into the cyclone dust collector 61 is guided to the cyclone chamber 614 via the inlet portion 612. The air guided to the cyclone chamber 614 flows upward while swirling along the outer peripheral surface of the grill portion 670.

[0070] Dust heavier than air may be scattered outward in a radial direction by centrifugal force and introduced into the dust collection chamber 615 via the opening 615a located at the upper portion of the cyclone chamber 614. The dust introduced into the dust collection chamber 615 may fall due to its weight and may be collected in the dust collection chamber 615.

[0071] The air in the cyclone chamber 614 from which dust is first removed by centrifugal force can be filtered while passing through the air through hole 672, so that dust particles of a predetermined size or larger can be filtered out for the second time. The air passing through the air through hole 672 can be guided upward via the outlet portion 614a. Fine dust in the air guided toward the middle cover 611a via the outlet portion 614a can be filtered out for the third time through the fine filter 68 provided on the middle cover 611a.

[0072] The finally purified air is discharged from the cyclone dust collector 61 via the outlet 613 of the upper cover 611, and is discharged to the outside of the main body 10 via the fan motor room (not shown). A filter (not shown) capable of filtering out dust in the air passing through the outlet 613 may be further provided at one side of the outlet 613 of the upper cover 611.

[0073] Figure 4 is an exploded perspective view showing a housing and a grill assembly of a cyclone dust collector according to one embodiment.

[0074] Reference Figure 4 According to one embodiment, the grille assembly 67 may be detachably installed in the cyclone dust collector 61. An inlet 612a through which air is introduced and an opening 612b through which the grille assembly 67 is inserted may be formed in the housing 610. The inlet 612a and the opening 612b may be formed in the lower cover 610a.

[0075] The opening 612b may be formed in a shape corresponding to the shape of the outer surface of the grille portion 670 so that the grille portion 670 may be inserted into the housing 610. As an example, in the case where the grille portion 670 is formed in a cylindrical shape, the opening 612b may be formed in a circular shape having the same diameter as the grille portion 670. The diameter D1 of the opening 612b may be the same as or slightly larger than the diameter D2 of the grille portion 670. The shape of the opening 612b is not limited to the above-mentioned shape. Hereinafter, an embodiment in which the grille portion 670 is formed in a cylindrical shape and the opening 612b is formed in a circular shape corresponding to the grille portion 670 will be described.

[0076] A coupling protrusion 619 configured to be coupled to the grille assembly 67 may be provided around the opening 612b. The coupling protrusion 619 may be provided to protrude from the outer surface of the lower cover 610a. A plurality of coupling protrusions 619 may be provided and disposed to be spaced apart from each other by a predetermined distance around the opening 612b. In the case where the opening 612b is formed in a circular shape, the coupling protrusions 619 may be disposed to be spaced apart from each other by a predetermined distance in the circumferential direction of the opening 612b.

[0077] Figure 5 and 6 is a view showing a coupling portion of a grill assembly and a case according to one embodiment.

[0078] Reference Figure 5 and 6 , the grille assembly 67 according to one embodiment may include a grille portion 670 in which an air passing hole 672 is formed, and a handle 671 provided at one side of the grille portion 670. When the grille assembly 67 is installed in the housing 610, the handle 671 may be located outside the housing 610 so that the user can manipulate the handle 671.

[0079] Irregularities may be formed on the surface of the handle 671 so that a user can easily manipulate the handle 671. The grill portion 670 and the handle 671 may be integrally injection molded.

[0080] The handle 671 may include an insertion portion 673a into which the coupling protrusion 619 provided on the lower cover 610a may be inserted, and an interference portion 673 configured to interfere with the coupling protrusion 619. The insertion portion 673a and the interference portion 673 may be arranged to correspond to the coupling protrusion 619 provided on the lower cover 610a. In the case where the opening 612b is formed in a circular shape and the coupling protrusion 619 is provided to protrude toward the circumferential outer side of the opening 612b, the insertion portion 673a and the interference portion 673 may also be arranged along the circumferential shape of the opening 612b to correspond to the opening 612b and the coupling protrusion 619.

[0081] In the case where a plurality of coupling protrusions 619 are provided to be spaced apart from each other by a predetermined distance in the circumferential direction of the opening 612 b , a plurality of interference portions 673 and a plurality of insertion portions 673 a may also be provided, and the interference portions 673 and the insertion portions 673 a may be alternately provided to correspond to the coupling protrusions 619 .

[0082] When the coupling protrusion 619 provided on the lower cover 610a is inserted through the insertion portion 673a and the grille assembly 67 is rotated in one direction, the coupling protrusion 619 may interfere with the adjacent interference portion 673. The interference portion 673 is interfered by the coupling protrusion 619, and the grille assembly 67 may be installed in the housing 610 and locked by the housing 610.

[0083] In order to separate the grille assembly 67 from the housing 610, the grille assembly 67 can be rotated in another direction. When the grille assembly 67 is rotated in another direction, the interference state of the interference portion 673 can be released. Therefore, the locked state of the grille assembly 67 can be released, and the grille assembly 67 can be separated from the housing 610.

[0084] The configuration in which the grille assembly 67 is coupled to or separated from the housing 610 is not limited to the above configuration. Although the embodiment in which the grille assembly 67 is installed in the lower cover 610a and separated from the lower cover 610a has been described above, in the case where the lower cover 610a and the housing 610 are integrally formed, the grille assembly 67 may also be considered to be installed in the housing 610 and separated from the housing 610.

[0085] Figures 7 to 9 is a view showing an aspect in which foreign matters on a surface of a grill portion according to one embodiment are separated therefrom.

[0086] Reference Figures 7 to 9 , the grille member 67 according to one embodiment may be provided to be detachable from the housing 610. When the grille member 67 is detached from the housing 610, hair, dust, etc. adhered to the surface of the grille portion 670 may be removed from the surface of the grille portion 670.

[0087] Hair, dust, etc. removed from the surface of the grille portion 670 may be contained in the housing 610. When the user clears the dust, etc. out of the housing 610, the user does not need to remove the hair, dust, etc. adhered to the surface of the grille portion 670 with his or her hands, but only needs to pour the dust contained in the housing 610 into the trash can B.

[0088] A cleaning portion 618 may be provided at the inner surface of the housing 610 adjacent to the opening 412. When the grille assembly 67 is separated from the housing 610, the cleaning portion 618 is provided to interfere with hair, dust, etc. adhered to the surface of the grille portion 670. The hair, dust, etc. on the surface of the grille portion 670 may be removed from the surface of the grille portion 670 by the cleaning portion 618. The dust, etc. removed from the surface of the grille portion 670 is not discharged through the opening 612b and remains in the housing 610.

[0089] The cleaning portion 618 may be provided to contact the surface of the grille portion 670. Even if the cleaning portion 618 does not contact the surface of the grille portion 670, the cleaning portion 618 may be provided adjacent to the grille portion 670 to interfere with hair, dust, etc. on the surface of the grille portion 670. In addition, the cleaning portion 618 may not be provided so that dust adhering to the surface of the grille portion 670 can be interfered with and removed by the inner surface of the opening 612b.

[0090] Hereinafter, an embodiment in which dust adhered to the surface of the grill portion 670 is removed by the cleaning portion 618 will be described.

[0091] In the cyclone chamber 614, a cyclone airflow may be generated, and the air from which dust is separated by the cyclone airflow may pass through the air through holes 672 provided in the grille portion 670. The air passing through the air through holes 672 may be discharged to the outside of the cyclone dust collector 61 via the outlet portion 614a.

[0092] Hair, dust, etc. separated from the air by the swirling airflow may be collected in the housing 610. The user may separate the swirling dust collector 61 from the extension tube 63 and the handle tube 64, open the upper cover 611, and clear the dust out of the housing 610.

[0093] Here, hair, dust, etc. may adhere to the surface of the grille portion 670. Generally, the user removes the hair, dust, etc. adhered to the surface of the grille portion 670 with his or her hands. When the hair, dust, etc. adhered to the surface of the grille portion 670 are removed, the removed dust may not be poured into the trash can B, but may be scattered around the trash can B, so that secondary pollution may occur. In addition, because the hair, dust, etc. are removed by hand, it is unhygienic.

[0094] In the present disclosure, the grille portion 670 is provided to be detachable from the shell 610, and when the grille portion 670 is separated from the shell 610, hair, dust, etc. adhered to the surface of the grille portion 670 are interfered by the cleaning portion 618 and removed from the surface of the grille portion 670.

[0095] The user does not need to remove hair, dust, etc. adhered to the surface of the grille part 670 with his or her hands, and can clean the surface of the grille part 670 only by separating the grille part 670 from the housing. The user only empties the housing 610 containing the dust removed from the surface of the grille part 670.

[0096] The user can make the first opening 411 of the housing 610 face the trash can B and separate the grille assembly 67 from the housing 610 to pour foreign matter into the housing 610. The dust collected in the housing 610 and the dust removed from the surface of the grille portion 670 can be poured into the trash can B.

[0097] As described above, since the grille assembly 67 of the cyclone dust collector 61 is detachably provided, dust and the like on the surface of the grille portion 670 can be removed, and secondary pollution can be prevented from occurring around the trash can B. In addition, since the user does not need to remove dust and the like with his or her own hands, it is hygienic.
