Description

Vacuum cleaner

Technical Field

This specification relates to vacuum cleaners.

Background

Such a vacuum cleaner can be divided into: a manual cleaner for cleaning while a user directly moves the cleaner; an automatic dust collector which can automatically run and clean at the same time.

Also, the manual vacuum cleaner may be classified into a horizontal vacuum cleaner, an upright vacuum cleaner, a hand-held vacuum cleaner, a stick type vacuum cleaner, and the like, according to the shape of the vacuum cleaner.

A hand-held cleaner may generally comprise a suction portion, a body, and a handle portion.

An extension pipe having an intake nozzle may be connected to the intake portion. Further, a battery for supplying power may be provided at the handle portion.

In the case where the suction nozzle includes a cleaning member for cleaning a carpet and a motor for rotating the cleaning member, the motor needs to receive power from the battery disposed in the handle portion.

In order for the motor to obtain power from a battery disposed in the handle portion, the battery needs to be connected with the motor via an electric wire for supplying power and an electric wire for transmitting a control signal. The electric wire is connected to the suction part through the body.

In addition, the body may include a dust bucket for storing dust, and the dust bucket may be formed to be transparent or translucent so that a user can confirm the dust stored inside with the naked eye.

However, since the electric wire is disposed in such a manner as to pass through the body, it is necessary to prevent the electric wire from being seen from the outside through the dust bucket.

Further, a hand-held vacuum cleaner is disclosed in Korean patent laid-open publication No. 10-1127088 (grant No. 2012.03.08), which is a prior art document.

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

The cleaner 1 may further include a suction part 5 coupled to a front of the body 2. The suction part 5 may guide air containing dust to the body 2.

The vacuum cleaner 1 may further include a handle portion 3 coupled to the body 2. The handle portion 3 may be located on the opposite side of the body 2 from the suction portion 5.

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

The body 2 may include: a first body 10; a second body 12 located at an upper side of the first body 10.

Although not limited, the first body 10 and the second body 12 may be formed in a cylindrical shape.

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

The body 2 may further include a dust separating portion for separating dust from air sucked through the suction portion 5.

For example, the dust separating part may include a first cyclone part 110 capable of separating dust by a cyclone (cyclone) flow. At this time, the first body 10 includes the first swirling portion 110.

The air and dust sucked through the suction part 5 spirally flow along the inner circumferential surface of the first swirling part 110.

The axis of the swirling flow of the first swirling portion 110 may extend in the vertical direction.

The dust separating part 10 may further include a second cyclone part 130, and the second cyclone part 130 may be used to separate dust from the air discharged from the first cyclone part 110 again. At this time, the second cyclone part 130 may be located inside the first cyclone part 110, so that the size of the dust separating part is minimized. The second swirling portion 130 may include a plurality of swirler bodies arranged in parallel.

As another example, the dust separating unit may include a single cyclone unit, and in this case, the axis of the cyclone flow may extend in the vertical direction.

The first body 10 functions as a dust bucket for storing dust separated from each of the

cyclone parts

110, 130. That is, the first body 10 includes the first cyclone part 110 and the dust bucket. At this time, in order to enable a user to confirm the amount of dust stored in the dust bucket with the naked eye, a portion or the whole of the first body 10 may be formed to be transparent or translucent.

The body 2 may further include a body cover 16 for opening and closing a lower side of the first body 10. The body cover 16 opens and closes the first body 10 by a rotational operation. The first body 10 may be provided with a button 18 for operating by rotating the body cover 16.

The hinge 162 of the main body cover 16 may be combined with a hinge coupling part 620 provided to the battery case 60.

At least a portion of the second cyclone part 130 may be located within the first body 10.

A dust storage guide 124 may be disposed in the first body 10, and the dust storage guide 124 guides storage of the dust separated from the second cyclone part 130. The dust storage guide 124 may be coupled to a lower side of the second cyclone part 130 and contact an upper surface of the main body cover 16.

The dust storage guide 124 may divide a space inside the first body 10 into a first dust storage part 121 for storing dust separated from the first cyclone part 110 and a second dust storage part 123 for storing dust separated from the second cyclone part 130.

The inner 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 main body cover 16 can open and close the first dust storage part 121 and the second dust storage part 123 together.

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

The suction motor 20 may be located within the second body 12. Further, at least a portion of the suction motor 20 may be positioned at an upper side of the dust separating part. Thereby, the suction motor 20 is located above the first body 10.

The suction motor 20 may communicate with an air outlet of the second cyclone part 130.

To this end, the body 2 may further include: a discharge guide 28 connected to the second swirling portion 130; a flow guide 22 in communication with the discharge guide 28.

For example, the discharge guide 28 is located above the second swirling portion 130, and the flow guide 22 is located above the discharge guide 28.

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

Thereby, the axis of the swirling flow of the dust separating portion can penetrate the suction motor 20.

When the suction motor 20 is positioned at the upper side of the second cyclone unit 130, the air discharged from the second cyclone unit 130 can directly flow toward the suction motor 20, and thus, a flow path between the dust separating unit and the suction motor 20 can be minimized.

The suction motor 20 may include an impeller (impeller)200 that performs a rotational action. The impeller 200 may be connected to a drive shaft (draft) 202. The drive shaft 202 is disposed to extend in the vertical direction.

An extension line of the driving shaft 202 (which may also be referred to as a rotation axis of the impeller 200) may pass through the first body 10. At this time, the rotation axis of the impeller 200 and the axis of the swirling flow generated by the first swirling portion 110 of the dust separating portion may be located on the same line.

According to the present invention, a path of the air discharged from the dust separating unit, that is, the air discharged upward from the second cyclone unit 130, toward the suction motor 20 is shortened, and a change in direction of the air is reduced, thereby reducing a flow loss of the air.

In the case where the flow loss of the air is reduced, the suction force can be increased, and the use time of the battery 40 for supplying power to the suction motor 20 can be increased.

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

The suction motor 20 may be accommodated in each of the motor housings 26 and 27, and the flow guide 22 may be disposed to surround the upper motor housing 26.

At least a portion of the flow guide 22 may be spaced from the upper motor housing 26. Also, at least a portion of the flow guide 22 may be spaced apart from the second body 12.

Thereby, the inner peripheral surface of the flow guide 22 and the outer peripheral surface of the upper motor case 26 form a first air flow path 232, and the outer peripheral surface of the flow guide 22 and the inner peripheral surface of the second body 12 form a second air flow path 234.

The air discharged from the second swirling portion 130 flows along the first air flow path 232 to the suction motor 20, and the air discharged from the suction motor 20 flows along the second air flow path 234 to be discharged to the outside. Thus, the second air flow path 234 functions as an exhaust flow path.

The handle portion 3 may include: a handle 30 for a user to hold; and a battery case 60 disposed below the handle 30.

The handle 30 may be located behind the suction motor 20.

When the direction is defined, the direction in which the suction unit 5 is located is the front direction and the direction in which the handle 30 is located is the rear direction with reference to the suction motor 20 in the vacuum cleaner 1.

The battery 40 may be positioned at the rear of the first body 10. Therefore, the suction motor 20 and the battery 40 may be arranged so as not to overlap in the vertical direction, and the arrangement heights thereof may be different.

According to the present invention as described above, since the suction motor 20 having a large weight is located in front of the handle 30 and the battery 40 having a large weight is located below the handle 30 with reference to the handle 30, the cleaner 1 can uniformly distribute the weight as a whole. When the user holds the handle 30 to perform cleaning, the user can be prevented from being excessively stressed on his wrist. That is, since the heavy structures are disposed at different heights in a dispersed manner on the front side and the rear side of the cleaner 1, the center of gravity of the cleaner 1 can be prevented from being shifted to one side.

Since the battery 40 is located below the handle 30 and the suction motor 20 is located in front of the handle 30, there is no structure above the handle 30. That is, the upper surface of the handle 30 forms a part of the appearance of the upper surface of the cleaner 1.

Therefore, it is possible to prevent: when the handle 30 is held and used, a structure of the cleaner 1 is in contact with an arm of a user.

The handle 30 may include: a first extension part 310 extending in an up-down direction and allowing a user to hold the first extension part 310; and a second extension part 320 extending from an upper side of the first extension part 310 toward the suction motor 20. At least a portion of the second extension 320 may extend in a horizontal direction.

The first extension part 310 may be provided with a movement restricting part 312, and the movement restricting part 312 may prevent a hand from moving in a longitudinal direction (vertical direction in fig. 2) of the first extension part 310 in a state where a user grips the first extension part 310. The movement restricting part 312 may extend from the first extending part 310 toward the suction part 5.

The movement restricting portion 312 is disposed to be spaced apart from the second extending portion 320. Therefore, in a state where the first extension portion 310 is gripped, some fingers are positioned above the movement restricting portion 312, and the remaining fingers are positioned below the movement restricting portion 312.

For example, the movement restricting part 312 may be located between the index finger and the middle finger.

According to such a configuration, the longitudinal axis a1 of the suction portion 5 can pass through the wrist of the user in a state where the user grips the first extension 310.

In a case where the longitudinal axis a1 of the suction unit 5 passes through the wrist of the user, the longitudinal axis a1 of the suction unit 5 may be substantially parallel to the extending direction of the arm of the user in a state where the user has spread the arm. Therefore, in such a state, there may be an advantage in that the force required to be consumed by the user is minimized when the user pushes or pulls the cleaner 1 while holding the handle 30.

The handle 30 may include an operating portion 326. For example, the operation portion 326 may be positioned on an inclined surface formed on the second extension 320. An opening command and a closing command of the vacuum cleaner (suction motor) can be input through the operation unit 326. For example, an on command and an off command of the suction motor 20 may be input by the operation unit 326. In addition, the suction strength of the suction motor 20 can be adjusted by the operation unit 326 in a state where the suction motor 20 is turned on.

The operation unit 326 may be disposed so as to face the user. The operation portion 326 may be located on the opposite side of the movement restricting portion 312 with respect to the handle 30.

The operation unit 326 is located at a higher position than the movement restricting unit 312. Therefore, the user can easily operate the operation portion 326 with the thumb while holding the first extension 310.

Further, since the operation unit 326 is located at a position away from the first extension portion 310, it is possible to prevent the operation unit 326 from being unintentionally operated when cleaning is performed with the first extension portion 310 being gripped.

The battery case 60 may be located at the lower side of the first extension 310.

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

The rear surface of the battery case 60 and the rear surface of the first extension 310 may form a continuous surface. Therefore, the battery case 60 and the first extension 310 may have an integral feeling.

In a state where the battery 40 is accommodated in the battery case 60, a lower surface of the battery 40 may be exposed to the outside. Therefore, when the cleaner 1 is placed on the ground, the battery 40 can be placed on the ground.

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

Further, since the lower surface of the battery 40 is exposed to the outside, the lower surface of the battery 40 can be directly in contact with the air outside the vacuum cleaner 1, and the cooling performance of the battery 40 can be improved.

The battery case 60 may include an outer case 600 and an inner case 610. The inner case 610 may be inserted into the lower side of the outer case 600.

The inner case 610 may be fixed to one or more of the outer case 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 accommodates the battery 40 in a state of being inserted into the outer case 600 and is combined with the battery 40, and thus, it is possible to prevent the outer case 600 from being deformed or to prevent the outer case 600 from being damaged in the process of mounting and separating the battery 40. Of course, the inner case 610 may not be additionally formed, and the inner case 610 may be formed integrally with the outer case 600.

The inner case 610 may include a pair of hinge coupling portions 620 coupled with the hinge 162 of the main body cover 16. The pair of hinge coupling portions 620 may be disposed to be spaced apart from each other at a fixed interval.

The inner case 610 may further include a charging-stand connection terminal 628, and the charging-stand connection terminal 628 is used to charge the battery 40 in a state where the battery 40 is mounted in the inner case 610. If the vacuum cleaner 1 is mounted on a charging stand, not shown, the terminals of the charging stand can contact with the charging stand connection terminals 628.

The battery case 600 may include a battery connection terminal 670, and the battery connection terminal 670 may be coupled to a battery terminal 490 provided in the battery 40 accommodated in the battery case 60. The battery connection terminal 670 may penetrate the upper side of the battery 40 and be coupled to the battery terminal 490.

In addition, referring to fig. 3, the cleaner 1 may further include a filter mechanism 50, the filter mechanism 50 having an air discharge opening 522 for discharging air passing through the suction motor 20. For example, the air outlet 522 may include a plurality of openings, and the plurality of openings may be arranged in a circumferential direction.

The filter mechanism 50 may be detachably coupled to the upper side of the body 2. The filter mechanism 50 may be detachably received in the second body 12.

In a state where the filter mechanism 50 is coupled to the body 2, a part of the filter mechanism 50 is positioned outside the second body 12. Thereby, a part of the filter mechanism 50 is introduced into the inside of the body 2 through the upper side opening of the body 2, and the other part protrudes to the outside of the body 2.

The height of the body 2 may be substantially the same as the height of the handle 30. Accordingly, since the filter mechanism 50 protrudes above the main body 2, the user can easily separate the filter mechanism 50 while holding the filter mechanism 50.

In a state where the filter mechanism 50 is coupled to the main body 2, the air outlet 522 is located above the filter mechanism 50. Thereby, the air discharged from the suction motor 20 is discharged upward of the main body 2.

According to the present embodiment, during cleaning by the vacuum cleaner 1, the air discharged from the air discharge opening 522 can be prevented from flowing toward the user side.

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

Fig. 6 is an exploded perspective view of a vacuum cleaner in accordance with an embodiment of the present invention, fig. 7 is a view illustrating a state in which a cover member is separated from a main body in accordance with an embodiment of the present invention, and fig. 8 is a perspective view of a first main body in accordance with an embodiment of the present invention.

Referring to fig. 6 to 8, the first body 10 and the second body 12 may be combined with each other in an up-down direction.

For this, the first body 10 may be provided with a first coupling portion 105, and the second body 12 may be provided with a second coupling portion 122.

The first coupling portion 105 may be a protrusion protruding from an outer circumferential surface of the first body 10. The second coupling portion 122 may extend downward from a lower side of the second body 12. The second combining portion 122 may be a hook for being locked to the protruding portion.

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

A cover member 70 may be coupled to the first body 10. The cover member 70 can prevent a plurality of

body wires

126, 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 tub 120).

A plurality of

body wires

126, 127 may be connected to the body terminal 80. The plurality of

body wires

126, 127 may include: two first body wires 126 connected to suction portion terminals (not shown) provided in the suction portion 5; and two second body wires 127 connected with the suction motor 20.

An extension pipe connected to an intake nozzle having a rotary cleaning member and a motor may be connected to the intake part 5, and when the extension pipe is connected to the intake part 5, the motor is electrically connected to the intake terminal, thereby receiving power from the battery 40. Alternatively, an intake nozzle having a rotary cleaning member and a motor may be directly connected to the intake part 5, in which case the motor of the intake nozzle may also receive power from the battery 40.

A portion of the plurality of

body wires

126, 127 may be introduced into the interior of the second body 12. Another portion of the plurality of

body wires

126 and 127 may be connected to the body terminal 80 after being extended downward from the second body 12 and guided by the cover member 70.

The cover member 70 may support the body terminals 80 connected to the

body wires

126, 127. Accordingly, the cover member 70 can prevent the body terminal 80 from being seen from the outside of the first body 10 (or the outside of the dust bucket 120).

Although not limited, the cover member 70 may be combined at an opposite side of the first body 10 from the suction part 5. When the cover member 70 is positioned on the opposite side of the first body 10 from the suction portion 5, it can be covered by the handle portion 3, and thus the cover member 70 can be prevented from being exposed to the outside.

The first body 10 may include a contact surface for seating the cover member 70, which is recessed toward the inside from the outer surface of the first body 10.

The contact surface may include: a first contact surface 101 formed to have a curvature; and second contact surfaces 102 which are plane and located on both sides of the first contact surface 101.

The first body 10 may further include a cover coupling hook 104 for coupling with the cover member (refer to reference numeral 70 of fig. 25).

The first body 10 may further include a first coupling portion 105 for coupling with the second body 12.

The cover coupling hook 104 may be provided at a lower side of the first coupling portion 105 to be spaced apart from the first coupling portion 105. The cover coupling hook 104 may extend downward in a state of being positioned below the first coupling portion 105, so as to prevent interference between the second coupling portion 122 coupled to the first coupling portion 105 and the cover coupling hook 104.

By disposing the second contact surfaces 102, which are flat surfaces, on both sides of the first contact surface 101, the cover member 70 can be prevented from rotating in the horizontal direction along the outer peripheral surface of the first body 10 in a state where the cover member 70 is coupled to the first body 10.

The first body 10 may include one or more movement preventing ribs 103, and the one or more movement preventing ribs 103 may stably maintain a state in which the cover member 70 is coupled thereto.

For example, in order to prevent the cover member 70 from moving up and down and left and right, a plurality of movement prevention ribs 103 may be provided on the first body 10.

The plurality of movement prevention ribs 103 may protrude from the first contact surface 101 of the first body 10, and may be arranged at intervals in the horizontal direction and the vertical direction.

As an example, two movement prevention ribs 103 spaced apart in the horizontal direction may extend in a direction away from each other.

An end 103a of at least a part of the plurality of movement preventing ribs 103 may be disposed to face the second contact surface 102 with a space from the second contact surface 102. That is, a space may be formed between the end 103a of the movement preventing rib 103 and the second contact surface 102.

The first body 10 may further include a case fastening part 108 for fastening with the inner case 610. A fastening member such as a screw may be fastened to the housing fastening portion 108.

In order to enable the fastening member to be fastened to the housing fastening part 108, a portion of the housing fastening part 108 may protrude outward from the first body 10, and another portion may protrude inward from the first body 10. As an example, the case fastening part 108 may protrude from the first contact surface 101 to the outside and the inside.

In order to enable the fastening member to be fastened to the case fastening part 108 in the up-down direction, the case fastening part 108 may extend in the up-down direction.

The case fastening part 108 may be disposed at a position spaced upward from the lower end of the first body 10.

Therefore, in order to enable the fastening member to be fastened to the case fastening part 108, the first body 10 may further include: a recessed space 106 providing a space for moving the fastening member; a guide groove 107 that guides the fastening member in the recessed space 106.

Referring to fig. 6 to 10, the cover member 70 may include a cover main body 710 contacting an outer surface of the first body 10.

The cap body 710 may include: a first cover main body 711 that contacts the first contact surface 101; and a second cover main body 712 located at both sides of the first cover main body 711 and contacting the second contact surface 102.

In order to bring the first cover main body 711 into contact with the first contact surface 101, the first cover main body 711 may include an arc-shaped surface.

In order to bring the second cover main body 712 into contact with the second contact surface 102, the second cover main body 712 may include a flat surface.

The cover body 710 may further include the receiving space 713 for disposing the second coupling portion 132 of the second body 12. The accommodation space 713 is formed at an upper center portion of the cover main body 710.

The cap body 710 may further include: a slot 714 for passing through the cover combining hook 104; and a hook locking portion 715 for locking the cover coupling hook 104 penetrating the insertion groove 714 to the hook locking portion 715.

The insertion groove 714 is located at a lower side of the receiving space 713. Therefore, according to the present invention, the cover coupling hooks 104 may pass through the accommodating space 713 and penetrate the insertion grooves 714, thereby being locked to the hook locking portions 715. Further, the second coupling portion 132 of the second body 12 may be located in the accommodating space 713 without interfering with the cover body 710.

Since the accommodating space 713 is a space disposed at a position spaced apart from both end portions of the cover main body 710, if the second coupling portion 132 of the second main body 12 is located in the accommodating space 713, the second coupling portion 132 can prevent the cover main body 710 from moving in the horizontal direction.

The cap body 710 may further include: a rib receiving space 718 for receiving the movement prevention rib 103 of the first body 10; a restricting rib 719 for restricting movement of the movement preventing rib 103 located in the rib accommodating space 718 from the first body 10 in a direction away from the first body in a radial direction; a rib supporting surface 720 supporting the movement preventing rib 103 received in the rib receiving space 718.

The restricting rib 719 may be located at a lower side of the inlet 718a of the rib receiving space 718.

The cover main body 710 may further include a second handle coupling part 721 for coupling with the handle part 3.

The second handle joint 721 may include: a first extension 722 extending in a horizontal direction from the cover main body 710; a second extension 723 extending upward from the first extension 722.

At least a portion of the second extension 723 may be disposed in a manner of facing the first face of the cap body 710.

In the present invention, a surface of the cover main body 710 that contacts the first main body 10 may be referred to as a second surface, and a surface opposite to the second surface may be referred to as a first surface.

Accordingly, an insertion opening 724 is formed between the second extension 723 and the first face of the cap body 710.

An insertion rib (304 in fig. 14) of the handle portion 3, which will be described later, may be inserted into the insertion opening 724.

The cover main body 710 may include a terminal coupling portion 716 for coupling with the body terminal 80. The terminal coupling portion 716 may include a plurality of coupling ribs 716a spaced apart in a horizontal direction, and coupling holes 716b for coupling with the body terminals 80 may be formed at the respective coupling ribs 716 a.

Accordingly, the body terminal 80 can be coupled to the coupling hole 716b in a state of being positioned between the plurality of coupling ribs 716 a.

When the body terminal 80 is coupled to the coupling hole 716b, the body terminal 80 can be prevented from sagging downward while the handle terminal 90 of the handle portion 3 is coupled to the body terminal 80.

At this time, the upper and lower lengths of the plurality of coupling ribs 716a may be formed to be greater than the upper and lower lengths of the body terminal 80. This is for the plurality of coupling ribs 716a to guide the coupling between the handle terminal (see 90 of fig. 14) and the body terminal 80 in the process of coupling the handle terminal (see 90 of fig. 14) and the body terminal 80, which will be described later.

The cover main body 710 may further include a terminal supporting portion 716c for supporting the body terminal 80. For example, the terminal support portion 716c may connect lower sides of the coupling ribs 716 a.

In a state where the body terminal 80 is supported by the terminal support portion 716c, the body terminal 80 can be prevented from sagging downward while the handle terminal 90 of the handle portion 3 is coupled to the body terminal 80.

The terminal coupling portion 716 may be provided at a first face of the cover main body 710.

The cover main body 710 may further include one or more guide ribs for guiding the plurality of

body wires

126, 127.

One or more of the guide ribs may include an upper guide rib 728 and a lower guide rib 728 a.

The plurality of

body wires

126, 127 are guided in position by the

guide ribs

728, 728a, and may be connected to the body terminal 80 at a lower side of the body terminal 80.

According to the present invention, the terminal coupling portion 716 is provided on the first surface of the cover main body 710, and the body terminal 80 is coupled to the terminal coupling portion 716, so that the cover main body 710 is positioned between the plurality of

body wires

126 and 127 and the body terminal 80 and the first main body 10 in a state where the plurality of

body wires

126 and 127 are connected to the lower surface of the body terminal 80.

Therefore, even if the first body 10 is formed to be transparent or translucent, the plurality of

body wires

126, 127 and the body terminal 80 can be prevented from being seen from the outside of the first body 10.

In order to prevent the cover main body 710 from interfering with the case fastening part 108 of the first body 10, the cover main body 710 may further include a fastening part receiving groove 726 in which the case fastening part 108 is located.

The cover main body 710 may further include a handle hook coupling portion 717 for coupling with a handle hook (see 306 of fig. 14) of the handle portion 3.

Fig. 11 is a transverse sectional view showing a state in which a lid member according to an embodiment of the present invention is coupled to a main body, fig. 12 is a longitudinal sectional view showing a state before the lid member according to the embodiment of the present invention is coupled to the main body, and fig. 13 is a longitudinal sectional view showing a state in which the lid member is coupled to the main body.

Referring to fig. 9 to 13, in order to couple the cover member 70 with the first body 10, the movement prevention rib 103 of the first body 10 is aligned with the inlet 718a of the rib receiving space 718 of the cover body 710.

In this case, a portion of the second coupling portion 132 of the second body 12 will be located in the receiving space 713 of the cover body 710.

In this state, the cover main body 710 is brought into contact with the first main body 10. That is, the first cover main body 711 contacts the first contact surface 101 of the first body 10, and the second cover main body 712 contacts the second contact surface 102 of the second body 12. In addition, the movement preventing rib 103 of the first body 10 is received in the rib receiving space 718.

As shown in fig. 13, in this state, the cover member 70 is moved upward. At this time, the movement prevention rib 103 of the first body 10 is seated on the rib seating surface 720, and the cover coupling hook 104 penetrates the insertion groove 714 of the cover body 710 and is latched to the hook latching part 715.

In a state where the cover coupling hook 104 is locked to the hook locking portion 715, the cover member 70 can be prevented from moving downward.

And, in a state that the movement preventing rib 103 of the first body 10 is seated on the rib seating surface 720, the cover member 70 is prevented from moving upward by the movement preventing rib 103.

Further, since the restricting rib 719 is located between the second contact surface 102 of the first body 10 and the movement preventing rib 103, the cover member 70 can be prevented from moving outward in the radial direction of the first body 10.

Referring to fig. 14, the handle part 3 may include a handle main body 300 contacting the outer surface of the body 2 and surrounding the outer surface of the body 2.

The handle body 300 may form the handle 3 and the battery case 60.

The handle body 300 may further include a case coupling rib 308 for coupling with the inner case 610.

In addition, the handle portion 3 may further include a handle terminal 90 for connection with the body terminal 80 coupled to the cover member 70.

The handle portion 3 may also include a plurality of

handle wires

942, 944, 946. A plurality of said

handle wires

Fig. 15 is a transverse sectional view showing a state in which the handle portion of fig. 14 is coupled to the cover member, fig. 16 is a longitudinal sectional view showing a state before the handle portion is coupled to the cover member, fig. 17 is a longitudinal sectional view showing a state in which the handle portion is coupled to the cover member, and fig. 18 is a view showing a state in which the handle portion is coupled to the body.

Referring to fig. 9, 14 to 18, in order to couple the handle portion 3 to the cover member 70, the insertion rib 302 of the handle portion 3 may be aligned with the insertion opening 724 of the second handle coupling portion 721 of the cover main body 710.

In this state, when the handle 3 is moved downward, the insertion rib 302 of the handle 3 passes through the insertion opening 324, is placed on the first extension 722 of the second handle coupling portion 721, and is locked to the second extension 723.

The handle hook 306 of the handle portion 3 is locked to the handle hook coupling portion 717 of the cover main body 710. The handle terminal 90 is connected to the body terminal 80. That is, the handle terminal 90 is connected to the body terminal 80 while the handle 3 is moved downward and coupled to the cover member 70.

At this time, the plurality of coupling ribs 716a of the cover member 70 guide the coupling of the handle terminal 90 and the body terminal 80. In addition, in a state where the handle terminal 90 is coupled to the body terminal 80, the plurality of coupling ribs 716a may cover a portion of both sides of the handle terminal 90.

Therefore, according to the present invention, since the handle terminal 90 is connected to the body terminal 80 in the process of coupling the handle portion 3 to the cover member 70, the coupling process between the handle terminal 90 and the body terminal 80 can be omitted, and thus there is an advantage in that the convenience of the user can be improved.

In this case, the handle portion 3 is slidably coupled to the cover member 70 by the insertion rib 302 of the handle portion 3 and the handle coupling portion 721 of the cover member 70, and therefore, there is an advantage that the handle terminal 90 and the body terminal 80 can be stably coupled to each other.

Fig. 19 is a perspective view showing a state in which the cover member is coupled to the body, fig. 20 is a perspective view showing a state in which the inner housing is coupled to the body to which the cover member is coupled, and fig. 21 is a sectional view showing a state in which the inner housing is coupled to the body.

Referring to fig. 19 to 21, in a state where the cover member 70 is coupled to the first body 10, a lower surface 729 of the cover member 70 is spaced apart from a lower surface of the first body 10. The lower surface 729 of the cover member 70 is located above the lower end of the case fastening portion 108 of the first body 10.

A space for providing the hinge coupling part 620 of the inner case 610 is formed between the lower surface 729 of the cover main body 70 and the lower end of the first main body 10.

A fastening rib 622 is provided between the pair of hinge coupling portions 620 of the inner case 610, and the fastening rib 622 is fastened to the case fastening portion 108 of the first body 10. The fastening rib 622 is connected to a pair of the hinge coupling portions 620.

The fastening rib 622 may include a fastening hole 624 to which a fastening member S is fastened.

A portion of the fastening rib 622 is located at the guide groove 107 of the first body 10. In a state where the fastening rib 622 is located in the guide groove 107, the fastening rib 622 contacts the lower surface of the case fastening part 108.

In this state, the fastening rib 622 and the case fastening part 108 may be fastened to each other below the fastening rib 622 by the fastening member S.

The inner case 610 may be provided with a rib locking portion 626 for being engaged with the case engaging rib 308 of the handle portion 3. For example, the rib locking portions 626 may be formed at the pair of hinge coupling portions 620, respectively.

Thereby, the inner case 610 may be coupled to the first body 10 and the handle part 3.

Referring to fig. 4, 18 and 22, as described above, the present invention may include the body 2, the handle portion 3 and the battery 40.

The cleaner 1 of the present invention generally has three coupling structures for supplying power.

The first coupling structure is a structure for coupling the battery 40 and the handle portion 3. In the present invention, the battery 40 is coupled to the handle portion 3 so as to be separable from the handle portion 3.

If the battery 40 is coupled to the handle part 3, the battery 40 is connected to the main PCB unit 340. At this time, the battery 40 and the handle portion 3 are mechanically coupled by the battery terminal 490 and the battery connection terminal 670. Of course, since the main PCB unit 340 is connected to the battery connection terminal 670 via a wire, if the battery terminal 490 and the battery connection terminal 670 are coupled, the battery terminal 490 and the battery connection terminal 670 are electrically connected to each other, so that the power of the battery 40 can be supplied to the main PCB unit 340.

A second coupling structure of the present invention is a structure for coupling the handle portion 3 and the body 2.

When the handle portion 3 is coupled to the body 2 in a state where the main PCB unit 340 is connected to the handle terminal 90 so as to slide in the vertical direction, the handle terminal 90 and the body terminal 80 are mechanically coupled to each other. Of course, if the handle terminal 90 and the body terminal 80 are mechanically coupled, the handle terminal 90 and the body terminal 80 are electrically connected to each other so that power can be supplied from the main PCB unit 340 to the body terminal 80 via the handle terminal 90.

In this case, the handle portion 3 is provided with a cover coupling portion 301, and the cover member 70 is provided with the insertion opening 724 and a handle hook coupling portion 717 for coupling with the cover coupling portion 301. Thereby, the handle portion 3 can be stably coupled to the cover member 70, and in this process, the handle terminal 90 can be accurately coupled to the body terminal 80. That is, the cover coupling portion 301, the insertion opening 724, and the handle hook coupling portion 717 function to guide the coupling between the handle terminal 90 and the body terminal 80, and thus there is an advantage in that an assembly error between the handle terminal 90 and the body terminal 80 can be reduced.

Further, since the main body coupling portion 304 is provided in the handle portion 3 and the first handle coupling portions 139a and 139b are provided in the second main body 12 of the main body 2, the handle portion 3 and the second main body 12 can be stably coupled to each other, and in this process, the handle terminal 90 can be accurately coupled to the main body terminal 80. That is, the main body coupling portion 304 and the first handle coupling portions 139a and 139b also serve to guide the coupling between the handle terminal 90 and the body terminal 80, and thus there is an advantage in that an assembly error between the handle terminal 90 and the body terminal 80 can be reduced.

As described above, the cover member 70 is provided with: a plurality of coupling ribs 716a coupled to the body terminal 80; and a terminal supporting portion 716c for supporting a lower side of the body terminal 80. Accordingly, the handle terminal 90 can prevent the body terminal 80 from drooping downward in the process of being coupled to the body terminal 80, and thus there is an advantage in that an assembly error between the handle terminal 90 and the body terminal 80 can be reduced.

The third coupling structure of the present invention is a coupling structure between the body wire electrically connected to the body terminal 80, the suction motor 20 provided inside the body 2, and the first terminal 139. Such a coupling structure is an electrical connection coupling structure that is located inside the main body 2 and is based on the connection of the respective main body electric wires. With such an electrical connection coupling structure, the power supplied to the body terminal 80 can be finally supplied to the suction motor 20 and the first terminal 139 side.

According to the coupling structure of the present invention, the flow path through which air flows is formed only in the main body 2, but not in the handle portion 3.

Therefore, when the handle portion 3 is coupled to the main body 2, it is not necessary to provide a structure for sealing a boundary portion between the handle portion 3 and the main body 2. Therefore, there is an advantage in that the structure for coupling the handle portion 3 and the body 2 becomes simple and coupling is easy.

In the present invention, the suction motor 20 and the first terminal 139 are members for receiving power from the battery 40, and thus may be referred to as a power supply and demand portion.
