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

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

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

That is, the main body 2 may be provided 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 located 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 approximately located at the boundary between the first body 10 and the second body 12.

The main body 2 may further include a dust separation unit that separates dust from the air sucked in through the suction unit 5.

The dust separation unit may include: a first dust separation unit 110, which may, for example, use a cyclone flow to separate dust. In this structure, the first body 10 includes a first dust separation unit 110.

The air and dust sucked in by the suction unit 5 spirally flow along the inner side of the first dust separation unit 110.

The axis of the cyclone flow in the first dust separation unit 110 may extend vertically.

The dust separation unit may further include: a second dust separation unit 130 that secondarily separates dust in the air discharged from the first dust separation unit 110. The second dust separation unit 130 may be disposed inside the first dust separation unit 110 to minimize the size of the dust separation unit. The second dust separation unit 130 may include a plurality of cyclone bodies arranged in a row.

As another example, the dust separation unit may include a dust separation unit, in which the axis of the cyclone flow may also extend vertically.

The first body 10 serves as a dust container to store the dust separated by the dust separating units 110 and 130. The upper part of the first body 10 is a first dust separation unit 110, and the lower part of the first body 10 is a dust container. The first body 10 may be partially or fully transparent or semi-transparent to enable the user to visually check the amount of dust in the dust container.

The main 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 rotating. The button 18 for rotating the body cover 16 may be provided on the first body 10.

The hinge 162 of the body cover 16 may be coupled to the hinge coupling part 620 of the battery case 60.

At least a part of the second dust separation unit 130 may be disposed in 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 provided 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 part 121 and a second dust storage part 123, wherein the first dust storage part 121 is used to store the dust separated by the first dust separation unit 110 Dust, the second dust storage part 123 is used to store the dust separated by the second dust separation unit 130.

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

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

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

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

The suction motor 20 may communicate with the outlet of the second dust separation unit 130.

To this end, the main body 2 may further include: a discharge guide 28 connected to the second dust separation unit 130; and a flow guide 22 communicated with the discharge guide 28.

For example, the discharge guide 28 is provided on the second dust separation unit 130, and the flow guide 22 is provided above the discharge guide 28.

In addition, at least a part of the suction motor 20 is provided inside the flow guide 22.

Therefore, the axis of the cyclone flow in the first dust separation unit 110 may pass through the suction motor 20.

When the suction motor 20 is disposed above the second dust separation unit 130, the air discharged from the second dust separation unit 130 can directly flow to the suction motor 20, so the passage between the dust separation unit and the suction motor 20 can be minimize.

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

An extension line from the shaft 202 (which can be regarded as the rotating shaft of the impeller 200) may pass through the first body 10. The rotation axis of the impeller 200 and the axis of the cyclone flow in the first dust separation unit 110 may be on the same line.

According to the present invention, there are the following advantages: it is possible to reduce the air discharged through the dust separation unit, that is, the path for the air discharged upward from the second dust separation unit 130 to flow to the suction motor 20, and the change in the direction of the air can be reduced, Therefore, the loss of air flow can be reduced.

Because the loss of airflow is reduced, the suction power 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 part of the top of the suction motor 20; and a lower motor housing 27 covering a part 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 provided inside the motor housings 26 and 27, and the flow guide 22 may be provided to cover the upper motor housing 26.

At least a part of the flow guide 22 may be separated from the upper motor housing 26. In addition, at least a part of the flow guide 22 may be separated from the second body 12.

Therefore, the first air passage 232 is defined by 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.

The air discharged from the second dust separation unit 130 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. Therefore, the second air passage 234 serves as an exhaust passage.

The handle unit 3 may include: a handle 30 for the user to hold; and a battery case 60 under the handle 30.

The handle 30 may be provided 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 arranged is the front direction, and the direction in which the handle 30 is arranged is the rear direction.

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

According to the present invention, because the heavy suction motor 20 is arranged in front of the handle 30 and the heavy battery 40 is arranged behind the handle 30, the weight can be evenly distributed throughout the entire vacuum 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, because the heavy components are distributed at the front and rear, and are distributed at different heights in the vacuum cleaner 1, it is possible to prevent the center of gravity of the vacuum cleaner 1 from being concentrated on either side.

Because the battery 40 is disposed under 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 vacuum cleaner 1 from contacting the user's arm when the user uses his/her hand to manipulate the handle 30 for cleaning.

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

A stopper 312 for preventing the user's hand holding the first extension part 310 from moving in the longitudinal direction of the first extension part 310 (the vertical direction in FIG. 2) may be formed in the first extension part 310. The extension 310 is on. The stopper 312 may extend from the first extension part 310 toward the suction unit 5.

The stopper 312 is separated from the second extension part 320. Therefore, the user should use part of the fingers above the stopper 312 and use other fingers below the stopper 312 to hold the first extension 310.

For example, the stopper 312 may 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 user's wrist.

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

The handle 30 may include an operating unit 326. For example, the operation unit 326 may be provided on the inclined surface of the second extension part 320. An instruction can be input through the operation unit 326 to turn on/off the cleaner (suction motor). For example, an instruction can be input through the operation unit 326 to turn on/off the suction motor. In addition, the suction strength of the suction motor 20 that has been turned on can be controlled through the operation unit 326.

The operation unit 326 may be arranged to face the user. The operating unit 326 may be disposed opposite to the stopper 312, and there is a handle 30 between the operating unit 326 and the stopper 312.

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

In addition, because the operating unit 326 is located outside the first extension 310, it is possible to prevent the operating unit 326 from accidentally operating when the user uses the first extension 310 in his/her hand for cleaning.

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

The battery 40 may be detachably combined with the battery case 60. For example, the battery 40 may 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. Therefore, the battery case 60 and the first extension 310 may be displayed as the same 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 contact the floor.

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

In addition, because 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 the battery 40 can be cooled more effectively.

The battery case 60 may include: an outer case 600; and an inner case 610. The inner housing 610 may be inserted under the outer housing 600.

The inner housing 610 may be fixed to one or more of the outer housing 600 and the first body 10. In addition, the battery 40 may be coupled to the inner case 610.

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

Obviously, the inner housing 610 may be formed integrally with the outer housing 600 without forming the inner housing 610 separately.

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

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

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

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 may include a plurality of openings, and the openings may be arranged in a circumferential manner.

The filter unit 50 may be detachably coupled to the top of the main body 2. The filter unit 50 may be detachably inserted in the second body 12.

When the filter unit 50 is combined with the main body 2, a part 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 the other parts protrude outward from the main body 2.

The height of the main body 2 may 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 part of the filter unit 50. Therefore, the air discharged from the suction motor 20 is discharged upward from the main body 2.

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

The main 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 provided inside the flow guide 22. In addition, the pre-filter 29 is disposed above the upper motor housing 26 and may surround a part of the upper motor housing 26. That is, the upper motor housing 26 may include: a filter support for supporting the pre-filter 29.

Figure 6 is a diagram showing when the vacuum cleaner is separated from the handle unit according to an embodiment of the present invention, Figure 7 is a diagram showing when a cover member has been separated from the main body according to an embodiment of the present invention, and the first Fig. 8 is a perspective view of a first body according to an embodiment of the present invention.

Referring to FIGS. 6 to 8, the first body 10 and the second body 12 may be vertically combined with each other.

To this end, the first body 10 has a first coupling portion 105 and the second body 12 has a second coupling portion 122.

The first coupling part 105 may be a protrusion formed on the outside of the first body 10. The second coupling portion 122 may extend downward from the lower portion of the second body 12. The second coupling portion 122 may be a hook that locks the protruding portion.

The first coupling portion 105 may be disposed at a predetermined distance from the upper end of the first body 10 so that the second coupling portion 122 extending downward from the lower portion of the second body 12 locks the first coupling portion 105.

The cover member 70 may be coupled to the first body 10. The cover member 70 can prevent the plurality of main body lines 126 and 127 for transmitting control signals and/or supplying power from being seen from the outside of the first body 10 (or the outside of the dust container 120).

The main body wires 126 and 127 may be connected to the main body terminal 80. The main body wires 126, 127 may include: two first main body wires 126 connected to the suction unit terminals in the suction unit 5 (Figure Not shown); and two second main body lines 127, connected to the suction motor 20.

An extension tube with a rotating cleaning unit and a motor connected to the suction nozzle can be connected to the suction unit 5 so that when the extension tube is connected to the suction unit 5, the motor is electrically connected to the suction unit terminals and can be supplied from the battery 40 electricity. Alternatively, a suction nozzle having a rotating cleaning unit and a motor may be directly connected to the suction unit 5 so that the motor of the suction nozzle can be supplied with electric power from the battery 40.

Part of the main body wires 126 and 127 may be inserted into the second body 12. The remaining main body wires 126, 127 may extend downward from the second body 12, may be guided by the cover member 70, and then may be connected to the main body terminal 80.

The cover member 70 may support the main body terminal 80 connected to the main body wires 126 and 127. Therefore, the cover member 70 can prevent the main body terminal 80 from being seen from the outside of the first body 10 (or the outside of the dust container 120).

Although not limited to this, the cover member 70 may be coupled to the opposite side of the suction unit 5 in the first body 10. When the cover member 70 is provided on the opposite side of the suction unit 5 in the first body 10, it can be covered by the handle unit 3 so that the cover member 70 cannot be exposed to the outside.

The first body 10 may have a recessed contact surface on the outer surface of the first body 10 to install the cover member 70.

The contact surface may include: a first contact surface 101; and a second contact surface 102 located on both sides of the first contact surface 101.

The first body 10 may further have a cover coupling hook 104 for coupling with the cover member 70.

The first body 10 may further have a first coupling portion 105 to be combined with the second body 12.

The cover coupling hook 104 may be disposed at a predetermined distance below the first coupling portion 105. The cover coupling hook 104 may extend upwardly below the first coupling portion 105 to prevent interference between the second coupling portion 122 and the cover coupling hook 104 that has been coupled to the first coupling portion 105.

Since the second contact surface 102 is provided on both sides of the first contact surface 101, the cover member 70 coupled to the first body 10 can be prevented from rotating horizontally around the first body 10.
