1 is a perspective view of a vacuum cleaner according to an embodiment of the present invention; FIG. 2 is a side view of a vacuum cleaner according to an embodiment of the present invention; and FIG. 3 is a plan view of a vacuum cleaner according to an embodiment of the present invention.

4 is a vertical sectional view of a vacuum cleaner according to an embodiment of the present invention; and FIG. 5 is a horizontal sectional view of a vacuum cleaner according to an embodiment of the present invention.

Referring to Figures 1 to 5, a vacuum cleaner 1 according to an embodiment of the present invention may include a main body 2.

The main body 2 may include a suction unit 5 that sucks in air containing dust.

The vacuum cleaner 1 may further include: a suction unit 5 coupled to the front of the main body 2. The suction unit 5 can guide the air containing dust to the main body 2.

The vacuum cleaner 1 may further include a handle unit 3 coupled to the main body 2. The handle unit 3 can be disposed opposite the suction unit 5 on the main body 2.

That is, the main body 2 can be disposed between the suction unit 5 and the handle unit 3.

The main body 2 may include: a first body 10; and a second body 12 on the first body 10.

The first body 10 and the second body 12 may be formed in a cylindrical shape, but are not limited thereto.

The suction unit 5 may be coupled to the main body 2 such that the center of the suction unit 5 is located substantially at the boundary between the first body 10 and the second body 12.

The main body 2 may further include a dust separating unit that separates the dust from the air taken in by the suction unit 5.

The dust separating unit 10 may include a first dust separating unit 110 that can separate dust, for example, using a cyclonic flow. In this configuration, the first body 10 includes a first dust removal unit 180.

The air and dust sucked in by the suction unit 5 spirally flow along the inner side of the first dust separation unit 180.

The axis of the cyclonic flow in the first dust removing unit 180 may extend vertically.

The dust separating unit may further include: a second dust separating unit 190 that secondarily separates dust in the air discharged from the first dust dividing unit 180. The second dust separation unit 190 may be disposed inside the first dust separation unit 180 to minimize the size of the dust separation unit. The second dust separation unit 190 may include a plurality of cyclone bodies arranged in a row.

As another example, the dust separating unit may include a dust separating unit, wherein the axis of the cyclonic flow may also extend vertically.

The first body 10 functions as a dust container that stores dust separated by the dust dividing units 180 and 190. That is, the first body 10 includes: a first dust removing unit 180 and a dust container. The upper portion of the first body 10 is the first dust removing unit 180, and the lower portion of the first body 10 is a dust container. The first body 10 may be partially or wholly transparent or translucent to enable the user to visually inspect the amount of dust in the dust container.

The body 2 may further include a body cover 16 for opening/closing the bottom of the first body 10. The body cover 16 can open/close the first body 10 by rotation.

At least a portion of the second dust separation unit 190 may be disposed within the first body 10.

A dust storage guide 124 that guides dust to be stored and separated by the second dust separation unit 130 may be disposed in the first body 10. The dust storage guide 124 may be coupled to the bottom of the second dust separation unit 130 that is in contact with the top of the body cover 16.

The dust storage guide 124 may divide the internal space of the first body 10 into a first dust storage portion 121 and a second dust storage portion 123, wherein the first dust storage portion 121 is configured to be stored by the first dust separation unit 180. Dust, the second dust storage portion 123 is for storing the dust separated by the second dust separation unit 130.

The internal space of the dust storage guide 124 is the second dust storage portion 123, and the space between the dust storage guide 124 and the first body 10 is the first dust storage portion 121.

The dust storage guide 124 of the present embodiment may be tapered at least partially downward. For example, a portion of the upper portion of the dust storage guide 124 may taper downward.

Further, the dust storage guide 124 may have an anti-flying rib 124a extending downward from the upper end of the dust storage guide 124. The anti-fly rib 124a may be formed, for example, in a cylindrical shape, and may surround the upper portion of the dust storage guide 124.

Since the upper portion of the dust storing guide 124 is tapered downward, a space is defined between the outer side of the upper portion of the dust storing guide 124 and the anti-flying rib 124a.

As described in the previous embodiment, the cyclonic flow generated along the inner side of the second body 10 can be moved downward. When the cyclonic flow comes into contact with the body cover 16 while moving downward, the swirling flow can be changed into the ascending airflow through the body cover 16. If there is an ascending air current in the first dust storage portion 121, the dust in the first dust storage portion 121 flies upward and flows backward into the second dust separation unit 130.

According to the present invention, in the space between the anti-flying rib 124a and the upper portion of the dust storing guide 124, the ascending airflow in the first dust storing portion 121 becomes the descending airflow due to the anti-flying rib 124a, so the first dust storing portion 121 The dust in the dust does not fly upward, so it does not flow backward into the second dust removing unit 130.

Further, since the rib 124a extends downward from the upper end of the dust storage guide 124, the dust separated by the swirling flow in the first dust dividing unit 110 can be smoothly fed into the first dust storing portion 121 through the anti-flying rib 124a.

The body cover 16 can open/close both the first dust storage portion 121 and the second dust storage portion 123.

The vacuum cleaner 1 may further include: a suction motor 20 for generating suction; and a battery 40 for supplying power to the suction motor 20.

The suction motor 20 may be disposed in the second body 12. At least a portion of the suction motor 20 may be disposed above the dust separation unit. Therefore, the suction motor 20 is disposed above the first body 10.

The suction motor 20 may be in communication with an outlet of the second dust separation unit 190.

To this end, the main body 2 may further include: a discharge guide 28 connected to the second dust separation unit 190; and a flow guide 22 in communication with the discharge guide 28.

For example, the discharge guide 28 is disposed on the second dust removal unit 190, and the flow guide 22 is disposed above the discharge guide 28.

Further, at least a portion of the suction motor 20 is disposed inside the flow guide 22.

Therefore, the axis of the cyclonic flow in the first dust removing unit 180 can pass through the suction motor 20.

When the suction motor 20 is disposed above the second dust removal unit 190, the air discharged from the second dust separation unit 190 may flow directly to the suction motor 20, so the passage between the dust separation unit and the suction motor 20 may minimize.

The suction motor 20 can include a rotating impeller 200. The impeller 200 can be mounted on the shaft 202. The shaft 202 is disposed vertically.

The suction motor 20 may be disposed such that the impeller 200 is disposed at an upper portion of the suction motor 20. According to this configuration, air can be blown downward through the impeller 200 in the suction motor 20.

An extension line from the shaft 202 (which can be considered as the axis of rotation of the impeller 200) can pass through the first body 10. The axis of rotation of the impeller 200 and the axis of the swirling flow in the first dust removing unit 180 may be on the same line.

According to the present invention, there is an advantage that the passage of air discharged from the dust separating unit, that is, the path of the air discharged upward from the second dust dividing unit 190 to the suction motor 20, and the change in the direction of the air can be reduced, Therefore, the loss of airflow can be reduced.

Since the loss of the airflow is reduced, the suction force can be increased, and the life of the battery 40 for supplying power to the suction motor 20 can be increased.

The cleaner 1 may further include: an upper motor housing 26 covering a portion of the top of the suction motor 20; and a lower motor housing 27 covering a portion of the bottom of the suction motor 20. The lower motor housing 27 may be integrally formed with the second body 12 or may be coupled to the second body 12.

The suction motor 20 may be disposed inside the motor housings 26 and 27, and the flow guide 22 may be disposed to cover the upper motor housing 26.

At least a portion of the flow guide 22 can be separated from the upper motor housing 26. Additionally, at least a portion of the flow guide 22 can be separated from the second body 12.

Therefore, the first air passage 232 is defined through the inner side of the flow guide 22 and the outer side of the upper motor housing 26, and the second air passage 234 is defined by the outer side of the flow guide 22 and the inner side of the second body 12.

According to the present invention, the single flow guide 22 forms the first air passage 232 and the second air passage 234, and the number of components of the air passage can be reduced, so that the structure is simplified.

The first air passage 232 acts as a suction passage and the second air passage 234 acts as an exhaust passage.

The air discharged from the second dust dividing unit 190 flows to the suction motor 20 through the first air passage 232, and the air discharged from the suction motor 20 flows through the second air passage 234 and then is discharged to the outside.

The handle unit 3 can include a handle 30 for the user to hold, and a battery housing 410 below the handle 30.

The handle 30 can be disposed behind the suction motor 20.

Regarding the direction, with respect to the suction motor 20 in the cleaner 1, the direction in which the suction unit 5 is disposed is the front direction, and the direction in which the handle 30 is provided is the rear direction.

The battery 40 can be disposed behind the first body 10. Therefore, the suction motor 20 and the battery 40 may be disposed not to overlap each other vertically, but may be disposed at different heights.

According to the present invention, since the heavy suction motor 20 is disposed in front of the handle 30, and the heavy battery 40 is disposed behind the handle 30, the weight can be evenly distributed throughout the cleaner 1. It is possible to prevent damage to the user's wrist when the user uses his/her hand to manipulate the handle 30 for cleaning. That is, since the heavy components are distributed at the front and the rear and are distributed at different heights in the cleaner 1, the center of gravity of the cleaner 1 can be prevented from being concentrated on either side.

Because the battery 40 is disposed below the handle 30 and the suction motor 20 is disposed in front of the handle 30, there are no components above the handle 30. That is, the top of the handle 30 forms a part of the appearance of the top of the cleaner 1.

Therefore, it is possible to prevent any element of the cleaner 1 from coming into contact with the user's arm when the user uses his/her hand to manipulate the handle 30 for cleaning.

The handle 30 can include a first extension 310 that extends vertically for the user to grip, and a second extension 320 that extends above the first extension 310 toward the suction motor 20. The second extension 320 can extend at least partially horizontally.

A stopper 312 for preventing a user from holding the first extending portion 310 from moving in the longitudinal direction of the first extending portion 310 (the vertical direction of FIG. 2) may be formed on the first extending portion 310. The stop 312 can extend from the first extension 310 toward the suction unit 5.

The stop 312 is spaced apart from the second extension 320. Therefore, the user should use some fingers above the stop 312 and use other fingers under the stop 312 to hold the first extension 310.

For example, the stop 312 can be located between the index finger and the middle finger.

According to this arrangement, when the user holds the first extension 310, the longitudinal axis A1 of the suction unit 5 can pass through the wrist of the user.

When the longitudinal axis A1 of the suction unit 5 is passed through the wrist of the user and the arm of the user is extended, the longitudinal axis A1 of the suction unit 5 can be substantially aligned with the extended arm of the user. Therefore, it is advantageous in this state that the user uses the minimum force when pushing or pulling the vacuum cleaner 1 having the handle 30 with his/her hand.

The handle 30 can include an operating unit 326. For example, the operation unit 326 may be disposed on the inclined surface of the second extension 320. An instruction can be input through the operation unit 326 to turn on/off the vacuum cleaner (suction motor).

The operation unit 326 can be set to face the user. The operating unit 326 can be disposed opposite the stop 312 with a handle 30 between the operating unit 326 and the stop 312.

The operation unit 326 is disposed higher than the stopper 312. Therefore, the user can easily operate the operation unit 390 with his/her thumb and the first extension 310 in his/her hand.

Further, since the operation unit 326 is located outside the first extension portion 310, it is possible to prevent the operation unit 326 from operating unexpectedly when the user performs cleaning using the first extension portion 310 in his/her hand.

A display unit 322 for displaying an operational state may be disposed on the second extension 320. The display unit 322 may be disposed, for example, at the top of the second extension 320. Therefore, the user can easily check the display unit 322 on the top of the second extension 320 while performing cleaning. The display unit 322 can display, for example, the remaining capacity of the battery 40 and the strength of the suction motor.

The display unit 322, although not limited, may include a plurality of light emitting units. The light emitting units may be separated from each other in the longitudinal direction of the second extension 320.

The battery case 60 may be disposed under the first extension 310.

The battery 40 can be detachably coupled to the battery case 60. For example, the battery 40 can be inserted into the battery case 60 from under the battery case 60.

The rear side of the battery case 60 and the rear side of the first extension 310 may form a continuous surface. Thus, battery housing 60 and first extension 310 can be displayed as a single unit.

When the battery 40 is inserted into the battery case 60, the bottom of the battery 40 may be exposed to the outside. Therefore, when the cleaner 1 is placed on the floor, the battery 40 can come into contact with the floor.

According to this configuration, there is an advantage that the battery 40 can be directly separated from the battery case 60.

Further, since the bottom of the battery 40 is exposed to the outside, the bottom of the battery 40 can be in direct contact with the air outside the cleaner 1, so that the battery 40 can be cooled more efficiently.

The battery case 60 may include an outer case 600 and an inner case 610. The inner casing 610 can be inserted under the outer casing 600.

The inner casing 610 can be fixed to one or a plurality of outer casings 600 and the first body 10. Additionally, battery 40 can be coupled to inner housing 610.

According to the present invention, the inner casing 610 is inserted into the outer casing 600, and then the battery 40 is inserted to be coupled to the inner casing 610, so that the outer casing 600 can be prevented from being deformed or prevented from being externally inserted 600 when the battery 40 is inserted or separated. damage.

The inner casing 610 may include a charging stand connection terminal 628 for charging the battery 40 coupled to the inner casing 610. The charging stand coupling terminal 628 can be brought into contact with the terminal of the charging stand (not shown) by placing the vacuum cleaner 1 on the charging stand.

The battery case 60 may include a battery connection terminal 670 that is connected to the battery terminal 490 inserted into the battery 40 in the battery case 60. Battery connection terminal 670 can be coupled to battery terminal 490 through the top of battery 40.

Obviously, the inner casing 610 can be integrally formed with the outer casing 600 without separately forming the inner casing 610.

The inner housing 610 can include a pair of hinge coupling portions 620 to which the hinge 162 of the body cover 16 is coupled. The hinge coupling portions 620 may be spaced apart from each other by a predetermined distance.

Referring to FIG. 3, the cleaner 1 may further include a filter unit 50 having an air outlet 522 for discharging air that has passed through the suction motor 20. For example, the air outlet 522 can include a plurality of openings that can be arranged in a circumferential manner. Therefore, the wire connecting the air openings may have a ring shape.

The filter unit 50 can be detachably coupled to the top of the body 2. The filter unit 50 can be detachably inserted in the second body 12. In a state where the longitudinal axis A1 is horizontally placed, the air outlet 522 is disposed above the suction motor.

When the filter unit 50 is combined with the main body 2, a portion of the filter unit 50 is located outside the second body 12. Therefore, a part of the filter unit 50 is inserted into the main body 2 through the open top of the main body 2, and other portions protrude outward from the main body 2.

The height of the body 2 can be substantially the same as the height of the handle 30. Therefore, the filter unit 50 protrudes upward from the main body 2, so the user can easily hold and separate the filter unit 50.

When the filter unit 50 is combined with the main body 2, the air outlet 522 is located at the upper portion of the filter unit 50. Therefore, the air discharged from the suction motor 20 is discharged upward from the main body 2.

According to the present embodiment, it is possible to prevent the air discharged from the air outlet 522 from flowing to the user when the user uses the cleaner 1 for cleaning.

The body 2 may further include a pre-filter 29 for filtering the air flowing into the suction motor 20. The pre-filter 29 may be disposed inside the flow guide 22. Further, a pre-filter 29 is disposed above the upper motor housing 16 and may surround a portion of the upper motor housing 26. That is, the upper motor housing 26 may include a filter support for supporting the pre-filter 29.

When the filter unit 50 is mounted on the main body 2, the filter unit 50 can press the pre-filter 29 to prevent the movement of the pre-filter 29.

For example, the filter unit 50 can press the pre-filter 29. Therefore, according to the present invention, a structure for fixing the pre-filter 29 is not required.

Figure 6 is a view showing when the filter unit according to an embodiment of the present invention has been separated from the main body; Figure 7 is a view showing the bottom of the filter unit according to an embodiment of the present invention; and Figure 8 is a view showing An exploded perspective view of the filter unit in Fig. 7; and Fig. 9 is a cross-sectional perspective view of the filter unit shown in Fig. 7.

Referring to Figures 5 to 9, the filter unit 50 can be separated from the main body 2.

For example, the filter unit 50 can be separated upward from the body 2.

Since the impeller 200 is located at an upper portion of the suction motor 20, the pre-filter 29 may be disposed to cover the upper motor housing 26 to cover the impeller 200.

Therefore, when the filter unit 50 is separated from the main body 2, the pre-filter 29 can be exposed outward, and therefore, the pre-filter 29 can be separated.

The pre-filter 29 can have a knob 29a. The user can separate the pre-filter 29 from the main body 2 by holding the knob 29a of the outwardly exposed pre-filter 29 and then lifting the pre-filter 29. Since the pre-filter 29 can be separated from the main body 2, the user can easily clean the pre-filter 29.

The filter unit 50 may further include: a filter 560 for filtering air discharged from the suction motor 20; and a filter frame for supporting the filter 560.

The filter 560 can be, for example, a High Efficiency Particulate Air (HEPA) filter.

The filter 560 can be positioned around the flow guide 22 to prevent the height of the cleaner 1 from being increased when the filter unit 50 is coupled to the body 2.

That is, the filter 560 can be formed, for example, in a ring shape, and a portion of the flow guide 22 can be positioned in a region defined by the filter 560.

Further, at least a portion of the pre-filter 29 may be inserted in an area defined by the filter 560. That is, the filter 560 surrounds the pre-filter 29. The filter frame can accommodate the annular filter 560.

The air opening 574 through which the air flows may be formed through the first side of the filter frame, and the air outlet 522 may be formed through the second side disposed opposite the first side, wherein air that has passed through the filter 560 passes through the An air outlet 522 is provided with a filter 560 between the first side and the second side.

The filter frame can be coupled to the flow guide 22 between the second body 12 and the flow guide 22.

The filter frame may have an inner frame 501 and an outer frame 540, and the outer frame 540 is disposed around the inner frame 501.

The outer side of the inner frame 501 and the inner side of the outer frame 540 are spaced apart from each other, and the filter 560 may be disposed between the inner frame 501 and the outer frame 540.

The filter frame may further include an exhaust frame 520 having an air outlet 522 and covering the top of the filter 560, and a filter cover 570 covering the bottom of the filter 560.

In particular, the inner frame 501 can include a top portion 502 and a circumferential side portion 503 that extends downwardly from the edge of the top portion 502.

The circumferential side portion 503 may include: a first member 503a; and a second member 503b extending downward from the first member 503a and having a larger diameter than the first member 503a.

The base 506 for the exhaust frame 520 may be formed between the first member 503a and the second member 503b by the difference in diameter between the first member 503a and the second member 503b.

The base 506 is formed along the circumferential side 503 at a predetermined distance below the top 502.

The exhaust frame 520 may be formed in a ring shape to be placed on the base 506. Further, the inner diameter of the exhaust frame 520 may be equal to or larger than the outer diameter of the first part 503a of the circumferential side portion 503. Further, the outer diameter of the base 506 and the second member 503b may be greater than the inner diameter of the exhaust frame 520.

Accordingly, the exhaust frame 520 may be disposed on the base 506, and the top portion 502 of the inner frame 501 and the first member 503a of the circumferential side portion 503 are fitted in the exhaust frame 520.

The filter unit 50 may further include an inner decorative member 510 coupled to an edge of the inner frame 501. The inner decorative member 510 may be formed in a ring shape.

The inner trim member 510 includes a hook member 512 for locking the inner frame 501.

A hook coupling hole 508 for locking the hook member 512 may be formed in the inner frame 501.

The hook coupling hole 508 may be formed in the first part 503a of the circumferential side portion 503. Further, a guide groove 507 for guiding the hook member 512 to the hook coupling hole 508 may be formed on the first member 503a of the circumferential side portion 503. The guide groove 507 may extend vertically.

Therefore, when the hook member 512 is aligned with the hook coupling hole 508 while moving along the guide groove 507, the hook member 512 can be inserted into the hook coupling hole 508.

The exhaust frame 520 is disposed on the base 506 of the inner frame 501, and then the inner trim member 510 can be coupled to the inner frame 501.

To this end, a guide groove 524 for providing a space in which the hook member 512 of the inner decorative member 510 can move may be formed on the inner side of the exhaust frame 520. The guide groove 524 may extend vertically.

Therefore, the hook member 512 of the inner decorative member 510 can move along the guide groove 507 of the inner frame 501 and the guide groove 524 of the exhaust frame 520.

When the inner trim member 510 is coupled to the inner frame 501, the inner trim member 510 may be disposed at the top of the exhaust frame 520.

Therefore, according to the present invention, a specific member for fixing the exhaust frame 520 to the inner frame 501 is not required.

The outer frame 540 can support the exhaust frame 520. The outer frame 540 can be secured to the exhaust frame 520, for example, by contact-engagement with the bottom of the exhaust frame 520. However, it should be noted that the manner in which the exhaust frame 520 and the outer frame 540 are fixed to each other is not limited in the present invention.

A receiving groove 544 for arranging the exhaust frame 520 may be formed on the outer frame 540 such that the outer frame 540 supports the exhaust frame 520.

When the outer frame 540 is fixed to the exhaust frame 520, a filter space is defined between the outer frame 540 and the circumferential side portion 503 of the inner frame, so the filter 560 can be inserted into the filter space. When the filter 560 is inserted into the filter space, it vertically overlaps the air outlet 522.

The filter unit 50 may further include an outer trim member 550 coupled to the outer frame 540. The outer trim component 550 can be coupled to the outer frame 540 when surrounding a portion of the circumference of the exhaust frame 520. Further, the outer trim member 550 may surround an upper portion of the outer frame 540. A base step 546 for arranging the lower end of the outer decorative member 550 may be formed outside the outer frame 540.

One or a plurality of coupling protrusions 554 for coupling the outer frame 540 may be formed inside the outer decorative member 550, and one or a plurality of coupling grooves 542 for receiving the coupling protrusions 554 may be formed at the outer frame 540. Outside.

When the user separates or couples the filter unit 50, the anti-slip portion 552 for preventing the user's hand from sliding may be formed outside the outer decorative member 550. The anti-slip portion 552 may be composed of, for example, a plurality of projections formed on the outer side of the outer decorative member 550.

The plurality of anti-slip portions 552 may be circumferentially spaced apart from each other around the outer decorative member 550 to effectively prevent sliding of the user's hand.

Filter cover 570 can be formed, for example, in a ring shape and can have one or more air openings 574 (which can be referred to as "air inlets").

The filter cover 570 may cover the filter 560 disposed between the outer frame 540 and the inner frame 501.

The filter cover 570 can support the outer frame 540 and the bottom of the inner frame 501, and can be combined with the outer frame 540 and the inner frame 501, for example, by engagement.

The filter unit 50 may further have sealing members 530 and 580 to seal the filter unit 50 and the body 2 when the filter unit 50 is coupled to the body 2.

Figure 10 is a cross-sectional view of a filter unit when coupled to a body in accordance with an embodiment of the present invention.

Referring to FIGS. 9 and 10, the sealing members 530 and 580 may include an inner sealing member 530 (or a first sealing member) for preventing air in the flow guide 22 from leaking through the hook coupling hole 508 of the inner frame 501. To the outside.

The inner seal member 530 may be coupled to the inner side of the circumferential side portion 503 of the inner frame 501.

In particular, the sealing rib 504 can extend downward from the top 502 of the inner frame 501. The sealing rib 504 is spaced apart from the circumferential side portion 503 of the inner frame 501. The sealing ribs 504 are continuously formed in the circumferential direction of the top portion 501.

Therefore, a space for inserting the inner seal member 530 is defined between the seal rib 504 of the inner frame 501 and the circumferential side portion 503, and a part of the inner seal member 530 is fitted in the space.

When the inner seal member 530 is coupled to the inner frame 501, the inner seal member 530 is in contact with the bottom of the first member 503a of the circumferential side portion 503, the inner side of the second member 503b, and the bottom of the seal rib 504.

Further, when the filter unit 50 is coupled to the main body 2, the inner seal member 530 is disposed at the upper end of the flow guide 22.

Therefore, according to the present invention, the inner seal member 530 is disposed at the upper end of the flow guide 22 that is in contact with the bottom of the first member 503a of the circumferential side portion 503, the inner side of the second member 503b, and the bottom of the seal rib 504, so that the flow is prevented. Air passing through the flow guide 22 flows into the hook coupling hole 508.

Further, the inner seal member 530 can prevent air from leaking to a gap between the outer side of the flow guide 22 and the inner side of the circumferential side portion 503 of the inner frame 501.

A gap may be provided between the outside of the filter unit 50 and the inside of the second body 12 to separate the filter unit 50 from the body 2.

Further, the sealing members 530 and 580 may further include: an outer sealing member 580 (or a second sealing member) for preventing air in the second air passage 234 from flowing into a gap between the outer frame 540 and the second body 12 without passing through Filter 560.

The outer sealing member 580 can be coupled to the edge of the filter cover 570. Although not limited, the outer sealing member 580 may be fitted to the filter cover 570 or may be integrally molded with the filter cover 570 by injection molding.

A support step 125 for supporting the outer sealing member 580 may be formed inside the second body 12. The support step 125 can be formed by increasing the thickness of the second body 12.

When the filter unit 50 is coupled to the body 2, the outer sealing member 580 can be disposed on the support step 125.

Therefore, the air in the second air passage 234 can be prevented from flowing into the gap between the outer frame 540 and the inner side of the second body 12.

Further, when the filter unit 50 is coupled to the main body 2, the outer decorative member 550 is disposed on the second body 12 of the main body 2. Therefore, the user can separate the filter unit 50 from the main body 2 by holding the outer decorative member 550 and rotating the filter unit 50 in a predetermined direction.

Further, when the filter unit 50 is coupled to the main body 2, a portion of the filter 560 may be disposed inside the main body, and another portion may be positioned outside the main body 2.

According to the present invention, since a portion of the filter unit 50 is exposed to the outside of the main body 2, the filter unit 50 can be held. Further, the filter 560 may be located inside the portion that protrudes outside the body 2, so the size of the filter 560 may be increased. Therefore, the area of the filter 560 that can be in contact with the air is increased, and the ability to purify the air can be improved.

11 is a perspective view of a filter cover according to an embodiment of the present invention; FIG. 12 is a cross-sectional view of the inner frame coupled to the filter cover shown in FIG. 11; and FIG. 13 is an embodiment of the present invention. A perspective view of a flow guide of the example; and Fig. 14 is a plan view of the flow guide in accordance with an embodiment of the present invention.

Referring to FIGS. 10 to 14, the filter cover 570 may include an inner body 571, an outer body 572 spaced apart from the inner body 571, and a connection body 573 that connects the inner body 571 and the outer body 572 to each other.

The inner body 571 and the outer body 572 may be formed in a ring shape.

One or more air openings 574 are formed by connecting the body 573. For example, a plurality of air openings 574 may be formed on the connecting body 573, and the wires connecting the plurality of air openings 574 may have a ring shape.

A plurality of frame support ribs 575 for supporting the bottom 509 of the inner frame 501 may be formed inside the inner body 571. The frame support ribs 575 can be circumferentially spaced apart on the inner body 571.

A rib coupling portion 577 for coupling the flow guide 22 may be formed inside the inner body 571.

The inner body 571 may include an extension 576 such that the rib coupling portion 577 may be inclined downward. The extension portion 576 protrudes downward at the bottom of the inner body 571, and the rib coupling portion 577 may be disposed at the extension portion 576.

Therefore, the rib coupling portion 577 extends downward from the end of the frame supporting rib 575 at an angle downward.

The downwardly inclined rib coupling portion 577 is for coupling the filter unit 50 and the main body or the separation filter unit 50 and the main body by rotating and lifting the filter unit 50 when the filter unit 50 and the main body 2 are separated.

When the filter unit 50 is lifted during the separation process, the user can know that the filter 50 is being separated.

In order to separate the filter unit 50 through the rotary filter unit 50, the rotational force should be applied to the filter unit 50, so the filter unit 50 is not separated from the main body 2 even if it is pulled out. Therefore, it is possible to prevent the filter unit 50 from being accidentally separated from the main body 2.

Each of the rib coupling portions 577 may include a slot 578 for receiving a fixing projection 2229 of the flow guide 22, which will be described below. The slot 578 can be a slot or a hole.

The inner frame 501 may further include a contact portion 509a extending downward from the bottom portion 509 of the inner frame 501. When the filter cover 570 and the inner frame 501 are combined, the contact portion 509a may be in contact with the side surface of the frame supporting rib 575.

The inner frame 501 may include a recessed portion 509b that is recessed upward to form a rib accommodation portion 579 for accommodating the fixing rib 228 of the flow guide 22.

When the inner frame 501 is combined with the filter cover 570, the recess 509b is spaced upwardly from the coupling rib 557.

The recessed portion 509b may be inclined such that when the filter unit 50 is rotated and moved downward, the fixing rib 228 of the flow guide 22 may be inserted into the rib accommodation portion 579 between the recessed portion 509b and the rib coupling portion 577.

Therefore, the rib accommodation portion 579 extends downward at an angle. The rib accommodation portion 579 can be regarded as a space between the inner frame 501 and the filter cover 570. That is, the fixing rib 228 of the flow guide 22 can be fitted between the inner frame 501 and the filter cover 570.

The flow guide 22 can include a guide body 220 that is open at the top and bottom. The guide body 220 may include a passage wall 222 for forming a first air passage 232 through which air discharged from the second dust removal unit 130 flows.

The channel wall 222 can protrude radially from the guide body 220.

The flow guide 22 can have a plurality of channel walls 222 spaced circumferentially for smooth airflow.

The suction motor 20 is positioned inside the flow guide 22, but in order not to increase the size of the body 2, the gap between the flow guide 22 and the suction motor 20 should be small. However, when the gap between the flow guide 22 and the suction motor 20 is small, the airflow is not smooth.

However, when the passage wall 222 protrudes from the guide body 220, as in the present invention, a sufficient cross-sectional area of the passage for the airflow can be ensured through the passage wall 222, so that the air can flow more smoothly.

The passage wall 222 is formed at a predetermined distance below the upper end of the flow guide 22 such that the upper portion of the flow guide 22 can be inserted inside the inner frame 501, and the passage wall 222 does not interfere with the filter unit 50.

Further, the outer diameter of the upper portion of the guide body 220 may be smaller than the inner diameter of the circumferential side of the inner frame 501. Therefore, when the filter unit 50 is coupled to the main body 2, the upper portion of the flow guide 22 is inserted into the filter unit 50, so the inner seal member 530 can be disposed at the upper end of the flow guide 22.

According to the present invention, since a part of the flow guide 22 is inserted into the filter unit 50, the increase in the height of the cleaner 1 can be minimized.

A filter support step 225 may be formed inside the guide body 220 to support the lower end of the pre-filter 29. The filter support step 225 may protrude inside the guide body 220.

A fastening portion 226 for fastening the motor housings 26 and 27 may be formed at a lower end of the guide body 220.

The fastening portion 226 of the guide body 220 may be disposed on the upper motor housing 26. In this state, the fastener S1 can be coupled to the upper motor housing 26 from above by the fastening portion 226.

The fastener S1 can be coupled to the discharge guide 28 after passing through the upper motor housing 26 and the lower motor housing 27. According to this configuration, a small amount of fasteners can be used to fasten the components, so that the structure is simple and the assembly is easy.

The flow guide 22 can include a securing rib 228 for coupling to the filter unit 50. The fixed ribs 228 may extend circumferentially at an angle such that when the filter unit 50 is rotated, the height of the filter unit 50 may be varied. Further, fixing projections 229 may be formed at the bottom of each of the fixing ribs 228.

At the same time, reinforcing ribs 227 may be formed on the channel wall 222. The flow guide 22 is spaced from the inner side of the second body 12 to form a second air passage 234.

The reinforcing ribs 227 can extend from the channel wall 222 toward the second body 12.

As described above, since the flow guide 22 is spaced apart from the inner side of the second body 12, the second body 12 can be deformed toward the flow guide 22 when an external force is applied to the second body 12.

However, according to the present invention, since the reinforcing rib 227 is formed on the passage wall 222, even if an external force is applied to the second body 12, the second body 12 is in contact with the reinforcing rib 227, so that the deformation of the second body 12 can be restricted.

Because the channel wall 222 protrudes from the guide body 220, the length of the reinforcing rib 227 can be reduced when the reinforcing rib 227 is formed on the channel wall 222.

Figure 15 is a view of a filter unit coupled to a flow guide in accordance with an embodiment of the present invention; and Figure 16 is a view after the filter unit is coupled to the flow guide in accordance with an embodiment of the present invention.

The process of combining the filter units 50 will be described with reference to Figs. 15 and 16.

A portion of the lower portion of the filter unit 50 is inserted into the second body 12 to couple the filter unit 50 to the body 2.

Therefore, the rib accommodation portion 579 and the fixing rib 228 of the filter unit 50 can be aligned.

In this state, the fixing rib 228 is placed in the rib housing portion 579 through the rotary filter unit 50. The rib accommodation portion 579 can be positioned higher than the fixing rib 228 so that the fixing rib 228 can be easily inserted into the rib accommodation portion 579.

Because the securing ribs 228 extend at an angle, the filter unit 50 moves downward through the securing ribs 228 as it rotates.

When the fixing projection 229 is inserted into the slit 578 of the rib coupling portion 577 and the fixing rib 228 is inserted into the rib housing portion 579, the filter unit 50 and the main body 2, that is, the flow guide 22 are combined.

At the same time, the filter unit 50 is rotated in the other direction to separate the filter unit 50 from the main body 2. Because the fixed rib 228 extends at an angle, the filter unit 50 moves upward through the fixed rib 228 as it rotates in that direction. When the fixing rib 228 is separated from the rib housing portion 579, the filter unit 50 is separated from the main body 2.

The filter unit 50 and the main body 2 can be separated by lifting the filter unit 50 in this state.

Figure 17 is a view showing the structure of a motor housing and a second body according to an embodiment of the present invention.

Referring to FIGS. 5 and 17, the lower motor housing 27 may be integrally formed with the second body 12.

A hole 273 for air flowing along the discharge guide 28 may be formed in the lower motor housing 27.

The lower motor housing 27 can support the upper motor housing 26. The first seal 274 may be disposed between the lower motor housing 27 and the upper motor housing 26.

The lower motor housing 27 may further include an air guide 272 for guiding air discharged from the suction motor 20 to the second air passage 234.

The upper motor housing 26 can support the flow guide 22. A second seal 274 can be disposed between the upper motor housing 26 and the flow guide 22.

Apertures 262 may also be formed in the upper motor housing 26 through which air that has passed through the apertures 273 of the lower motor housing 27 passes.

Fig. 18 is a longitudinal sectional view showing a flow of air in a vacuum cleaner according to an embodiment of the present invention; and Fig. 19 is a horizontal sectional view showing an air flow in a vacuum cleaner according to an embodiment of the present invention.

The air flow in the cleaner 1 is described with reference to Figs. 17 to 19.

The air and dust sucked in through the suction unit 5 of the suction motor 20 are separated from each other while flowing along the inner side of the first dust separation unit 110.

The dust separated from the air falls into the first dust storage portion 121. The air separated from the dust flows into the second dust dividing unit 130. The air flowing in the second dust separation unit 130 is again separated from the dust.

The dust separated from the air in the second dust separation unit 130 falls into the second dust storage portion 123. On the other hand, the air separated from the dust in the second dust separation unit 130 is discharged upward from the second dust separation unit 130 to the suction motor 20.

The air discharged from the second dust removing unit 130 flows through the discharge guide 28, passes through the hole 273 of the lower motor housing 27, and then flows upward through the first air passage 232 of the flow guide 22. Further, the air in the first air passage 232 passes through the pre-filter 29.

The air that has passed through the pre-filter 29 passes through the suction motor 20 in the upper motor housing 27. Air flows through the impeller 200 in the suction motor 20 and is then discharged to the lower motor housing 27. The air discharged into the lower motor housing 27 is redirected by the air guide 272 and sent to the second air passage 234.

Further, the air flowing into the second air passage 234 is discharged to the outside through the air outlet 522 after passing through the filter 560.

According to the present invention, the air passage is formed only in the main body and is not formed in the handle unit 3. Therefore, it is not necessary to seal the structure of the node between the handle unit 3 and the main body 2 when the handle unit 3 is coupled to the main body 2. Therefore, the structure in which the handle unit 3 is coupled to the main body 2 is simple, and coupling is easy.

Figure 20 is a view showing a battery according to an embodiment of the present invention when it has been separated from a battery case; Figure 21 is a perspective view of a battery according to an embodiment of the present invention; and Figure 22 is a view showing a battery according to an embodiment of the present invention; A diagram of a coupling slot of a battery housing.

Referring to Figures 20 through 22, battery 40 can include a plurality of battery cells (not shown); and a frame 450 that protects the battery cells.

A protrusion 460 is formed at the top of the frame 450, and a terminal 462 may be disposed in the protrusion 460.

Battery 40 can include a plurality of couplings 470 and 480. The coupling portions 470 and 480 may include a first coupling portion 470 disposed on a first side of the frame 450 and a second coupling portion 480 disposed on a second side of the frame 450. The first coupling portion 470 and the second coupling portion 480, for example, may be disposed to face each other.

The first coupling portion 470 can be a hook member that is rotatably coupled to the frame 450.

When the battery 40 is inserted into the battery case 410, the first coupling portion 470, for example, may be coupled to the hinge coupling portion 420. Therefore, the hinge coupling portion 420 may be referred to as a battery coupling portion.

A locking rib 422 for locking a portion of the hinge coupling portion 470 may be formed on the hinge coupling portion 420.

As another example, the hinge coupling portion 420 may be integrally formed with the battery case 410, or the locking rib 422 may be formed on the battery case 410.

The second coupling portion 480 may be a hook member integrally formed with the frame 450 and may be deformed by an external force.

An opening 411 for inserting the battery 40 is formed at the bottom of the battery case 410. An exposed opening 415 for exposing the second coupling portion 480 to the outside may be formed such that the second coupling portion 480 can be operated with the battery 40 in the battery case 410.

A coupling groove 416 for coupling the second coupling portion 480 may be formed over the exposed opening 415 in the battery case 410.

When the battery 40 is inserted into the battery case 410, a space 530 for operating the first coupling portion 470 is defined between the dust container 50 and the first coupling portion 470.

Accordingly, the user can place the finger into the space 530 and unlock the locking rib 422 from the first coupling portion 470. Further, the user can unlock the second coupling portion 480 from the battery case 410 by operating the second coupling portion 480 exposed to the outside of the battery case 410.

According to the present invention, since the battery 40 can be separated from the battery case 410, only the battery 40 can be placed in the charging stand for charging.

Further, since the cleaner 1 includes the body terminal 600, the battery 4 can be charged by placing the cleaner 1 and the battery 40 in the battery case 410 on the charging stand.

Figure 23 is a diagram when a vacuum cleaner equipped with a nozzle is used to clean the floor.

Referring to Fig. 23, an extension tube 700 having a suction nozzle 710 extending from the lower end may be coupled to the suction unit 5 of the vacuum cleaner 1 of the present invention.

In this state, the user can perform cleaning by moving the nozzle 710 on the floor.

When the user performs cleaning using the suction nozzle 710 of the present invention, he/she can perform cleaning while changing the angle between the extension tube 70 and the floor from about 45 degrees.

The suction motor 20 and the battery 40 can be positioned opposite each other with the vertical line VL passing through the lowermost end of the first body 10 therebetween. That is, the suction motor 20 is located on one side of the vertical line VL (for example, before the vertical line VL), and the battery 40 is disposed on the other side (for example, after the vertical line VL). The vertical line VL can pass through the handle 30.

Further, in the state shown in Fig. 23, the suction motor 20 and the battery 40 are almost the same height from the floor.

Thus, when the user holds the handle 30 and sweeps the floor, the weight of the cleaner is balanced from the user's hand holding the handle to balance the front and rear sides to maintain weight balance. In this case, the user can use the vacuum cleaner 1 to clean with a small force, and the wrist applied to the user can be prevented from being injured.

Further, in the process of cleaning the floor, as shown in Fig. 23, the filter unit 50 is disposed before the vertical line VL, and the user's hand holding the handle is located behind the vertical line VL. Therefore, the air discharged through the filter unit 50 flows away from the handle 30, so that the air discharged through the filter unit 50 can be prevented from flowing to the user's hand.

Obviously, depending on the angle between the extension tube 700 and the floor, only a portion of the suction motor 20 and the battery 40 are positioned relative to each other with respect to the vertical line VL therebetween. This situation corresponds to the case of cleaning a specific space such as a window frame or a sofa.

When the hinge coupling portion is formed to be separated from the first body 910 , the hinge coupling portion may be coupled to the first body 910 .

The hinge 922 of the body cover 920 can be located between the axis A2 of the cyclonic flow and the battery 40.

Therefore, when the body cover 920 is rotated about the hinge 922, the body cover 920 is rotated toward the user as shown in FIG.

After the body cover 920 is rotated toward the user, the body cover 920 prevents dust from flying toward the user when dust in the first body 910 is dropped.

The body cover 920 can include a coupling rod 950 that can be moved by a user and coupled to the first body 910. The coupling rod 950 can be coupled in parallel with the longitudinal axis of the suction unit 5.

The body cover 920 can include a first guide 924 that can guide the coupling rod 950 and prevent the coupling rod 950 from separating downward. The first guide 924 extends downward from the body cover 920 and at least a portion of the first guide 924 is located below the coupling rod 950.

The body cover 920 can further include a second guide 926 that can guide the coupling rod 950 and prevent the coupling rod 950 from separating downward. The second guide 926 protrudes from one side of the body cover 920 and can pass through the coupling rod 950.

The second guide 926 can pass through a coupling rod 950 that is parallel to the longitudinal axis of the suction unit 5. A hole 954 of the second guide 926 may be formed in the coupling rod 950.

The coupling rod 950 can have an annular portion 952 for the user to easily operate the coupling rod 950 by placing a finger therein. The annular portion 952 can be located between the hinge 922 of the body cover 920 and the axis A2 of the cyclonic flow so that the user can easily contact the annular portion 952.

The coupling rod 950 includes a coupling hook 956, and the first body 910 may include a hook groove 914 for locking the coupling hook 956.

The coupling hook 956 can be locked to the hook groove 914 inside the first body 510. Although not shown in the drawings, an elastic member may be disposed between the body cover 920 and the coupling rod 950, wherein the elastic member applies an elastic force to the coupling rod 950 to keep the coupling hook 956 locked in the hook groove 914.

When the user pulls the annular portion 952 of the coupling rod 950 toward himself/herself, the coupling hook 956 is pulled out from the hook groove 914, so the body cover 920 can be rotated.

In another aspect, the hinge coupling portion can include a body terminal 1000 for charging the battery 40 in the battery housing 410. The charging stand terminal can be brought into contact with the main body terminal 100 by placing the vacuum cleaner 1 on a charging stand (not shown).

The body terminal 1000 is disposed at the bottom of the hinge coupling portion, but may be separated from the floor when the cleaner 1 is placed on the floor. Therefore, damage to the body terminal 1000 can be prevented.
