Patent Description:
Cleaners may be classified into a manual cleaner that a user moves in person for cleaning and an automatic cleaner that automatically moves for cleaning.

Manual cleaners may fall into, depending on the types, a canister cleaner, an upright cleaner, a handy cleaner, and a stick cleaner.

Handy cleaners, generally, may include a suction unit, a body, and a handle.

An extension pipe having a suction nozzle may be connected to the suction unit. Further, a battery for supplying power may be disposed in the handle.

When the suction nozzle includes a cleaning unit for sweeping carpets and a motor for rotating the cleaning unit, the motor is supposed to be supplied with power from the battery.

In order to supply power to the motor from the battery in the handle, the battery should be connected with the motor through a power supply wire and a control signal wire. The wires are connected to the suction unit through the body.

A PCB for controlling the motor may be disposed in the body or the handle.

However, handy cleaners are small in volume in comparison to other cleaners, so it is difficult to combine the PCB and connect the wires in the assembly process.

Meanwhile, in the related art, a handheld vacuum cleaner has been disclosed in <CIT>). <CIT> relates to a cleaning appliance comprising a body that is connectable to a separating apparatus at an interface that defines an axis. The interface includes a first interface portion and a second interface portion that are connected to one another by connecting means, wherein the connecting means includes at least one radially interlocking region extending about at least a portion of the interface. <CIT> relates to another cleaning appliance comprising a main body and a separating apparatus including a dirt collector having a base that is openable that allows the dirt collector to be emptied. The cleaning appliance includes an actuator that is operable sequentially such that, during a first operation, the actuator causes the base to be opened and, during a second operation, the actuator causes the dirt collector to disengage from the separating apparatus.

The present disclosure provides a cleaner that can be easily assembled.

The present disclosure provides a cleaner of which terminals can be connected in the process of assembling the cleaner without a user connecting the terminals.

The present disclosure provides a cleaner of which terminals can be reduced in size by separating a wire for supplying power and a wire for transmitting control signals from each other.

A cleaner includes: a suction unit that guides dust and air; a main body that includes a dust separation unit for separating dust from air guided through the suction unit; a main body terminal that is mounted on the main body; a handle unit that is slide-coupled to the main body; and a handle terminal that is mounted on the handle unit and is connected to the main body terminal when the handle unit is slide-coupled to the main body.

A cleaner includes: a suction unit that guides air and dust; a main body including a suction motor generating suction force to suck air through the suction unit; a main body terminal that is mounted on the main body and connected with the suction motor through wires; a handle unit that is coupled to the main body; a battery that is separately connected to the handle unit to supply power to the suction motor; and a handle terminal that is mounted on the handle unit, connected with the battery, and mechanically connected with the main body terminal when the handle unit is coupled to the main body.

According to the invention, since the main body is assembled, the handle unit is assembled, and the handle unit is slide-coupled to the main body, the process of combining the main body unit and the handle unit using screws is removed, so the cleaner can be more simply assembled.

Further, since the handle terminal is mounted on the handle unit, the main body terminal is mounted on the main body unit, and the main body terminal is coupled to the handle terminal when the handle unit is slide-coupled to the main body, there is no need for a process of separately connecting the terminals.

Further, since the main body has the connecting terminal, the handle unit has the main PCB, and the main PCB is coupled to the connecting terminal when the handle unit is slide-coupled to the main body, there is no need for a process of connecting the main PCB to the connecting terminal.

Further, since the handle terminal and the main body terminal include only power terminals without a signal terminal for controlling the suction motor, it is possible to prevent an increase in size of the handle terminal and the main body terminal.

Further, since the main body terminal is mounted on the cover member and the wires connected to the main body terminal are guided by the cover member, the wires cannot be seen from the outside through the dust container even if the dust container is made of a transparent material or a translucent material.

<FIG> is a perspective view of a cleaner according to an embodiment of the present invention, <FIG> is a side view of the cleaner according to an embodiment of the present invention, <FIG> is a plan view of the cleaner according to an embodiment of the present invention, <FIG> is a perspective view of the cleaner according to an embodiment of the present invention when seen from under the cleaner, and <FIG> is a cross-sectional view of the cleaner according to an embodiment of the present invention.

Referring to <FIG>, a cleaner <NUM> according to an embodiment of the present invention may include a main body <NUM>.

The cleaner <NUM> may further include a suction unit <NUM> coupled to the front of the main body <NUM>. The suction unit <NUM> can guide air containing dust into the main body <NUM>.

The cleaner <NUM> may further include a handle unit <NUM> coupled to the main body <NUM>. The handle unit <NUM> may be positioned opposite to the suction unit <NUM> on the main body <NUM>.

That is, the main body <NUM> may be disposed between the suction unit <NUM> and the handle unit <NUM>.

The main body <NUM> may include a first body <NUM> and a second body <NUM> on the first body <NUM>.

The first body <NUM> and the second body <NUM> may be, though not limited thereto, formed in a cylindrical shape.

The suction unit <NUM> may be coupled to the main body <NUM> such that the center of the suction unit <NUM> is positioned approximately at the boundary between the first body <NUM> and the second body <NUM>.

The main body <NUM> may further include a dust separation unit that separates dust from air sucked through the suction unit <NUM>.

The dust separation unit may include a first cyclone unit <NUM> that can separate dust, for example, using cyclonic flow. The first body <NUM> includes the first cyclone unit <NUM> in this configuration.

The air and dust sucked through the suction unit <NUM> helically flow along the inner side of the first cyclone unit <NUM>.

The axis of the cyclonic flow in the first cyclone unit <NUM> may vertically extend.

The dust separation unit may further include a second cyclone unit <NUM> that secondarily separates dust from the air discharged out of the first cyclone unit <NUM>. The second cyclone unit <NUM> may be disposed inside the first cyclone unit <NUM> to minimize the size of the dust separation unit. The second cyclone unit <NUM> may include a plurality of cyclone bodies arranged in a raw.

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

The first body <NUM> functions as a dust container that stores dust separated by the cyclone units <NUM> and <NUM>. That is, the first body <NUM> includes the first cyclone unit <NUM> and the dust container. The upper part of the first body <NUM> is the first cyclone unit <NUM> and the lower part of the first body <NUM> is the dust container. The first body <NUM> may be partially or entirely transparent or translucent to enable a user to visually check the amount of dust in the dust container.

The main body <NUM> may further include a body cover <NUM> for opening/closing the bottom of the first body <NUM>. The body cover <NUM> can open/close the first body <NUM> by being rotated.

At least a portion of the second cyclone unit <NUM> may be positioned inside the first body <NUM>.

A dust storage guide <NUM> that guides the dust separated by the second cyclone unit <NUM> to be stored may be disposed in the first body <NUM>. The dust storage guide <NUM> may be coupled to the bottom of the second cyclone unit <NUM> in contact with the top of the body cover <NUM>.

The dust storage guide <NUM> may divide the internal space of the first body <NUM> into a first dust storage part <NUM> where the dust separated by the first cyclone unit <NUM> is stored and a second dust storage part <NUM> where the dust separated by the second cyclone unit <NUM> is stored.

The internal space of the dust storage guide <NUM> is the second dust storage part <NUM> and the space between the dust storage guide <NUM> and the first body <NUM> is the first dust storage part <NUM>.

The body cover <NUM> can open/close both of the first dust storage part <NUM> and the second dust storage part <NUM>.

The cleaner <NUM> may further include a suction motor <NUM> for generating suction force and a battery <NUM> for supplying power to the suction motor <NUM>.

The suction motor <NUM> may be disposed in the second body <NUM>. At least a portion of the suction motor <NUM> may be disposed over the dust separation unit. Accordingly, the suction motor <NUM> is disposed over the first body <NUM>.

The suction motor <NUM> may communicate with an outlet of the second cyclone unit <NUM>.

To this end, the main body <NUM> may further include a discharge guide <NUM> connected to the second cyclone unit <NUM> and a flow guide <NUM> that communicates with the discharge guide <NUM>.

For example, the discharge guide <NUM> is disposed on the second cyclone unit <NUM> and the flow guide <NUM> is disposed over the discharge guide <NUM>.

Further, at least a portion of the suction motor <NUM> is positioned inside the flow guide <NUM>.

Accordingly, the axis of the cyclonic flow in the first cyclone unit <NUM> may pass through the suction motor <NUM>.

When the suction motor <NUM> is disposed over the second cyclone unit <NUM>, the air discharged from the second cyclone unit <NUM> can flow directly to the suction motor <NUM>, so the channel between the dust separation unit and the suction motor <NUM> can be minimized.

The suction motor <NUM> may include a rotary impeller <NUM>. The impeller <NUM> may be fitted on a shaft <NUM>. The shaft <NUM> is vertically disposed.

An extension line from the shaft <NUM> (which may be considered as the rotational axis of the impeller <NUM>) may pass through the first body <NUM>. The rotational axis of the impeller <NUM> and the axis of the cyclonic flow in the first cyclone unit <NUM> may be on the same line.

According to the present invention, there is the advantage that the path through which the air discharged from the dust separation unit, that is, the air discharged upward from the second cyclone unit <NUM> flows to the suction motor <NUM> can be reduced and a change in direction of air can be decreased, so a loss of airflow can be reduced.

As the loss of airflow is reduced, suction force can be increased and the lifetime of the battery <NUM> for supplying power to the suction motor <NUM> can be increased.

The cleaner <NUM> may further include an upper motor housing <NUM> covering a portion of the top of the suction motor <NUM> and a lower motor housing <NUM> covering a portion of the bottom of the suction motor <NUM>. The lower motor housing <NUM> may be integrally formed with the second body <NUM> or may be coupled to the second body <NUM>.

The suction motor <NUM> may be disposed inside the motor housings <NUM> and <NUM> and the flow guide <NUM> may be disposed to cover the upper motor housing <NUM>.

At least a portion of the flow guide <NUM> may be spaced apart from the upper motor housing <NUM>. Further, at least a portion of the flow guide <NUM> may be spaced apart from the second body <NUM>.

Accordingly, a first air passage <NUM> is defined by the inner side of the flow guide <NUM> and the outer side of the upper motor housing <NUM> and a second air passage <NUM> is defined by the outer side of the flow guide <NUM> and the inner side of the second body <NUM>.

The air discharged from the second cyclone unit <NUM> flows to the suction motor <NUM> through the first air passage <NUM> and the air discharged from the suction motor <NUM> flows through the second air passage <NUM> and is then discharged outside. Accordingly, the second air passage <NUM> functions as an exhaust channel.

The handle unit <NUM> may include a handle <NUM> for a user to hold and a battery housing <NUM> under the handle <NUM>.

The handle <NUM> may be disposed behind the suction motor <NUM>.

As for directions, with respect to the suction motor <NUM> in the cleaner <NUM>, the direction in which the suction unit <NUM> is positioned is the front direction and the direction in which the handle <NUM> is positioned is the rear direction.

The battery <NUM> may be disposed behind the first body <NUM>. Accordingly, the suction motor <NUM> and the battery <NUM> may be arranged not to vertically overlap each other and may be disposed at different heights.

According to the present invention, since the suction motor <NUM> that is heavy is disposed ahead of the handle <NUM> and the battery <NUM> that is heavy is disposed behind the handle <NUM>, so weight can be uniformly distributed throughout the cleaner <NUM>. It is possible to prevent injuries to the user's wrist when a user cleans with the handle <NUM> in his/her hand. That is, since the heavy components are distributed at the front and rear portions and at different heights in the cleaner <NUM>, it is possible to prevent the center of gravity of the cleaner <NUM> from concentrating on any one side.

Since the battery <NUM> is disposed under the handle <NUM> and the suction motor <NUM> is disposed in front of the handle <NUM>, there is no component over the handle <NUM>. That is, the top of the handle <NUM> forms a portion of the external appearance of the top of the cleaner <NUM>.

Accordingly, it is possible to prevent any component of the cleaner <NUM> from coming in contact with the user's arm while the user cleans with the handle <NUM> in his/her hand.

The handle <NUM> may include a first extension <NUM> extending vertically to be held by a user and a second extension <NUM> extending toward the suction motor <NUM> over the first extension <NUM>. The second extension <NUM> may at least partially horizontally extend.

A stopper <NUM> for preventing a user's hand holding the first extension <NUM> from moving in the longitudinal direction of the first extension <NUM> (vertically in <FIG>) may be formed on the first extension <NUM>. The stopper <NUM> may extend toward the suction unit <NUM> from the first extension <NUM>.

The stopper <NUM> is spaced apart from the second extension <NUM>. Accordingly, a user is supposed to hold the first extension <NUM>, with some of the fingers over the stopper <NUM> and the other fingers under the stopper <NUM>.

For example, the stopper <NUM> may be positioned between the index finger and the middle finger.

According to this arrangement, when a user holds the first extension <NUM>, the longitudinal axis A1 of the suction unit <NUM> may pass through the user's wrist.

When the longitudinal axis A1 of the suction unit <NUM> passes through the user's wrist and the user's arm is stretched, the longitudinal axis A1 of the suction unit <NUM> may be substantially aligned with the user's stretched arm. Accordingly, there is the advantage in this state that the user uses minimum force when pushing or pulling the cleaner <NUM> with the handle <NUM> in his/her hand.

The handle <NUM> may include an operation unit <NUM>. For example, the operation unit <NUM> may be disposed on an inclined surface of the second extension <NUM>. It is possible to input instructions to turn on/off the cleaner (suction motor) through the operation unit <NUM>.

The operation unit <NUM> may be disposed to face a user. The operation unit <NUM> may be disposed opposite to the stopper <NUM> with the handle <NUM> therebetween.

The operation unit <NUM> is positioned higher than the stopper <NUM>. Accordingly, a user can easily operate the operation unit <NUM> with his/her thumb with the first extension <NUM> in his/her hand.

Further, since the operation unit <NUM> is positioned outside the first extension <NUM>, it is possible to prevent the operation unit <NUM> from being unexpectedly operated when a user cleans with the first extension <NUM> in his/her hand.

The battery housing <NUM> may be disposed under the first extension <NUM>.

The battery <NUM> may be detachably combined with the battery housing <NUM>. For example, the battery <NUM> may be inserted into the battery housing <NUM> from under the battery housing <NUM>.

The rear side of the battery housing <NUM> and the rear side of the first extension <NUM> may form a continuous surface. Accordingly, the battery housing <NUM> and the first extension <NUM> can be shown like a single unit.

When the battery <NUM> is inserted in the battery housing <NUM>, the bottom of the battery <NUM> may be exposed to the outside. Accordingly, when the cleaner <NUM> is placed on the floor, the battery <NUM> can be in contact with the floor.

According to this structure, there is the advantage that the battery <NUM> can be directly separated from the battery housing <NUM>.

Further, since the bottom of the battery <NUM> is exposed to the outside, the bottom of the battery <NUM> can come in direct contact with the air outside the cleaner <NUM>, so the battery <NUM> can be more efficiently cooled.

The battery housing <NUM> may include an outer housing <NUM> and an inner housing <NUM>. The inner housing <NUM> may be inserted under the outer housing <NUM>.

The inner housing <NUM> may be fixed to one or more of the outer housing <NUM> and the first body <NUM>. Further, the battery <NUM> may be coupled to the inner housing <NUM>.

According to the present invention, the inner housing <NUM> is inserted into the outer housing <NUM> and then the battery <NUM> is inserted to be coupled to the inner housing <NUM>, so it is possible to prevent the outer housing <NUM> from deforming or to prevent the outer housing <NUM> from being damaged when inserting or separating the battery <NUM>.

The inner housing <NUM> may include charging stand connection terminals <NUM> for charging the battery <NUM> coupled to the inner housing <NUM>. It is possible to bring the charging stand connection terminals <NUM> in contact with terminals of a charging stand (not shown) by placing the cleaner <NUM> on the charging stand.

The battery housing <NUM> may include battery connection terminals <NUM> that are connected to battery terminals <NUM> in the battery <NUM> inserted in the battery housing <NUM>. The battery connection terminals <NUM> may be connected to the battery terminals <NUM> through the top of the battery <NUM>.

Obviously, it may be possible to integrally form the inner housing <NUM> with the outer housing <NUM> without separately forming the inner housing <NUM>.

The inner housing <NUM> may include a pair of hinge coupling portions <NUM> to which a hinge <NUM> of the body cover <NUM> is coupled. The hinge coupling portions <NUM> may be spaced at a predetermined distance from each other.

Referring to <FIG>, the cleaner <NUM> may further include a filter unit <NUM> having air exits <NUM> for discharging the air that has passed through the suction motor <NUM>. For example, the air exits <NUM> may include a plurality of openings and the openings may be circumferentially arranged.

The filter unit <NUM> may be detachably coupled to the top of the main body <NUM>. The filter unit <NUM> may be detachably inserted in the second body <NUM>.

When the filter unit <NUM> is combined with the main body <NUM>, a portion of the filter unit <NUM> is positioned outside the second body <NUM>. Accordingly, a portion of the filter unit <NUM> is inserted in the main body <NUM> through the open top of the main body <NUM> and the other portion protrudes outside from the main body <NUM>.

The height of the main body <NUM> may be substantially the same as the height of the handle <NUM>. Accordingly, the filter unit <NUM> protrudes upward from the main body <NUM>, so a user can easily hold and separate the filter unit <NUM>.

When the filter unit <NUM> is combined with the main body <NUM>, the air exits <NUM> are positioned at the upper portion of the filter unit <NUM>. Accordingly, the air discharged from the suction motor <NUM> is discharged upward from the main body <NUM>.

According to this embodiment, it is possible to prevent the air discharged from the air exits <NUM> from flowing to a user while the user cleans using the cleaner <NUM>.

The main body <NUM> may further include a pre-filter <NUM> for filtering the air flowing into the suction motor <NUM>. The pre-filter <NUM> may be disposed inside the flow guide <NUM>. Further, the pre-filter <NUM> is seated over the upper motor housing <NUM> and may surround a portion of the upper motor housing <NUM>. That is, the upper motor housing <NUM> may include a filter support for supporting the pre-filter <NUM>.

<FIG> is an exploded perspective view of the cleaner according to an embodiment of the present invention and <FIG> is a view showing a support body and a sealing member according to an embodiment of the present invention.

Referring to <FIG>, the main body <NUM> may be disposed between the suction unit <NUM> and the handle unit <NUM>. The first body <NUM> and the second body <NUM> may be, for example, vertically arranged.

The cleaner <NUM> may further include a sealing member <NUM> and a support body <NUM> supporting the sealing member <NUM> to seal the boundary between the first body <NUM> and the second body <NUM> that have been combined.

The first body <NUM> and the second body <NUM> may be open at the top and the bottom, respectively. That is, the bodies <NUM> and <NUM> may include a top opening and a bottom opening, respectively.

The support body <NUM> may be formed in a cylindrical shape. The outer diameter of the support body <NUM> may be made the same as or smaller than the inner diameter of the first body <NUM> so that the support body <NUM> can be inserted into the first body <NUM> through the top opening of the first body <NUM>.

Further, the outer diameter of the support body <NUM> may be made the same as or smaller than the inner diameter of the second body <NUM> so that the support body <NUM> can be inserted into the second body <NUM> through the bottom opening of the second body <NUM>.

The support body <NUM> may include an opening <NUM>.

The sealing member <NUM> may be fitted around the support body <NUM>. For example, the sealing member <NUM> may be integrally formed with the support body <NUM> through injection molding. Alternatively, the sealing member <NUM> may be attached to the outer side of the support body <NUM> through an adhesive.

The support body <NUM> may include a first seating groove <NUM> extending around the support body <NUM> and a second seating groove145 extending from the first seating groove <NUM> at a different height from the first seating groove <NUM>.

The sealing member <NUM> can be seated in the seating grooves <NUM> and <NUM>.

The first seating groove <NUM> may be formed at a position that approximately bisects the height of the support body <NUM>. The second seating groove <NUM> bypasses the opening <NUM>. For example, the second seating groove <NUM> is positioned under the opening <NUM>.

Accordingly, the sealing member <NUM> may include a first section <NUM> that is seated in the first seating groove <NUM> and a second section <NUM> that continues from the first section <NUM> and is seated in the second seating groove <NUM>.

When the sealing member <NUM> is seated in the seating grooves <NUM> and <NUM>, a portion of the sealing member <NUM> may protrude from the support body <NUM>. Since the sealing member <NUM> fitted on the support body <NUM> protrudes from the support body <NUM>, the sealing member <NUM> can be positioned at the boundary between the first body <NUM> and the second body <NUM> even though the support body <NUM> is inserted in the first body <NUM> and the second body <NUM>, whereby sealing is possible.

Fixing holes <NUM> where portions of the sealing member <NUM> are positioned are formed in the seating grooves <NUM> and <NUM>. As portions of the sealing member <NUM> are inserted in the fixing holes <NUM>, the sealing member <NUM> can be prevented from rotating circumferentially around the support body <NUM>.

The suction unit <NUM> may include a pipe <NUM> that is connected to the main body <NUM>, a pipe cover <NUM> that covers the pipe <NUM>, and a cover deco-member <NUM> that surrounds a portion of the pipe cover <NUM> to be coupled to the pipe <NUM>.

<FIG> is a perspective view of the first body according to an embodiment of the present invention and <FIG> is a front view of the first body shown in <FIG>.

Referring to <FIG> and <FIG>, the first body <NUM> may include a recessed contact surface on the outer side. A cover member <NUM> (see <FIG>) may be seated on the recessed contact surface.

The contact surface may include a rounded first contact surface <NUM> and flat second contact surfaces <NUM> at both sides of the first contact surface <NUM>.

The first body <NUM> may further include a cover coupling hook <NUM> for coupling the cover member <NUM> (see <FIG>).

The first body <NUM> may further include a first coupling portion <NUM> to be combined with the second body <NUM>.

The first coupling portion <NUM> may protrude from the outer side of the first body <NUM> and the top of the first coupling portion <NUM> may be inclined downward for easy combination with the second body <NUM>.

The first coupling portion <NUM> may be disposed at a predetermined distance downward from the upper end of the first body <NUM>. The first body <NUM> may include one or more reinforcing ribs for preventing damage to the first coupling portion <NUM>.

The cover coupling hook <NUM> may be disposed at a predetermined distance under the first coupling portion <NUM>. The cover coupling hook <NUM> may extend downward under the first coupling portion <NUM>.

Since the second contact surfaces <NUM> are disposed at both sides of the first contact surface <NUM>, it is possible to prevent the cover member <NUM> (see <FIG>) coupled to the first body <NUM> from horizontally rotating around the first body <NUM>.

The first body <NUM> may include one or more locking ribs <NUM> for maintaining the cover member <NUM> (see <FIG>) stably coupled.

For example, the first body <NUM> may include a plurality of locking ribs <NUM> to prevent up-down and left-right movement of the cover member <NUM> (see <FIG>).

The locking ribs <NUM> may protrude from the first contact surface <NUM> of the first body <NUM> and may be horizontally and vertically spaced apart from each other.

For example, two horizontally spaced locking ribs <NUM> may extend away from each other.

Ends 103a of at least some of the locking ribs <NUM> may be arranged to face the second contact surfaces <NUM> at a predetermined distance from the second contact surfaces <NUM>. That is, spaces may be defined between the ends 103a of the locking ribs <NUM> and the second contact surfaces <NUM>.

The first body <NUM> may further include a housing fastening portion <NUM> to be fastened to the inner housing <NUM>. A fastener such as a screw may be coupled to the housing fastening portion <NUM>.

In order that the fastener can be coupled to the housing fastening portion <NUM>, a portion of the housing fastening portion <NUM> may protrude outward from the first body <NUM> and the other portion may protrude inward from the first body <NUM>. For example, the housing fastening portion <NUM> may protrude outward and inward from the first contact surface <NUM>.

The housing fastening portion <NUM> may vertically extend so that the fastener can be vertically coupled to the housing fastening portion <NUM>.

The housing fastening portion <NUM> may be spaced upward from the lower end of the first body <NUM>.

Accordingly, the first body <NUM> may further include a recession <NUM> that provides a space for movement of a fastener and a guide groove <NUM> that guides the fastener in the recession so that the fastener can be coupled to the housing fastening portion <NUM>.

A first recession <NUM> that is recessed inward may be formed at the upper portion of the first body <NUM>.

A body receiving part <NUM> that provides a space for holding a portion of the second body <NUM> may be formed at the first recession <NUM>.

The body receiving part <NUM> may be formed by cutting downward the upper end of the first body <NUM>.

The first body <NUM> may further include a pipe coupling portion <NUM> (or a suction unit coupling portion) for coupling the pipe <NUM>. The pipe coupling portion <NUM> may protrude from the first body <NUM> under the body receiving part <NUM>.

The pipe coupling portion <NUM> may include one or more main body fastening bosses <NUM> to which fasteners are coupled.

The sealing member <NUM> may be seated on the body receiving part <NUM>. In detail, the second section <NUM> of the sealing member <NUM> may be seated on the body receiving part <NUM>.

A stopper rib <NUM> that prevents the second section <NUM> seated on the body receiving part <NUM> from moving away from the support body <NUM> may be disposed on the top of the pipe coupling portion <NUM>. Since the second section <NUM> of the sealing member <NUM> is rounded, the stopper rib <NUM> may be rounded to come in contact with the second section <NUM> of the sealing member <NUM>.

Accordingly, the first section <NUM> of the sealing member <NUM> can be seated on the upper end of the first body <NUM> and the second section <NUM> of the sealing member <NUM> can be seated on the body receiving part <NUM>.

The pipe coupling portion <NUM> on the first recession <NUM> may be covered by the pipe <NUM>.

<FIG> is a perspective view of the second body according to an embodiment of the present invention. <FIG> is a front view of the second body according to an embodiment of the present invention.

Referring to <FIG> and <FIG>, the second body <NUM> may include a cylindrical part <NUM>. A second recession 120a that is recessed inward may be formed at a lower portion of the cylindrical part <NUM>.

The second body <NUM> may further include an extension <NUM> that extends downward from the lower end of the second recession 120a of the cylindrical part <NUM>.

The extension <NUM> may be formed in a shape corresponding to the body receiving part <NUM> of the first body <NUM>. The extension <NUM> may be positioned on the body receiving part <NUM> of the first body <NUM> and seated on the second section <NUM> of the sealing member <NUM>.

The second body <NUM> may include a suction opening <NUM> through which the air guided through the suction unit <NUM> flows inside.

The suction opening <NUM> may be formed at the cylindrical part <NUM> and the extension <NUM> inside the recession 120a.

The reason that the extension <NUM> extends downward from the cylindrical part <NUM> and a portion of the suction opening <NUM> is formed at the extension <NUM> is for positioning the suction unit <NUM> around the middle of the height of the main body <NUM> without a large difference in height between the first body <NUM> and the second body <NUM>.

According to this structure, the longitudinal axis A1 of the suction unit <NUM> can be positioned between the suction motor <NUM> and the second cyclone unit <NUM>.

If the longitudinal axis A1 of the suction unit <NUM> passes through the suction motor <NUM>, there is a need for a channel for guiding air to the first cyclone unit <NUM> around the suction motor <NUM> and the diameter of the main body <NUM> is accordingly increased.

However, the lower the longitudinal axis A1 of the suction unit <NUM>, the smaller the height of the first cyclone unit <NUM>, so the ability to separate dust is deteriorated.

Therefore, according to the present invention, since the longitudinal axis A1 of the suction unit <NUM> is positioned between the suction motor <NUM> and the second cyclone unit <NUM>, it is possible to maintain the ability to separate dust and prevent the diameter or the size of the main body <NUM> from increasing.

The second body <NUM> may further include a suction guide <NUM> for guiding air to the suction opening <NUM>. The suction guide <NUM> may tangentially protrude from the second body <NUM>.

A locking protrusion <NUM> for locking the pipe <NUM> may be formed on the suction guide <NUM>.

Further, the second body <NUM> may include a main body fastening boss <NUM> for fastening the pipe <NUM> using a fastener.

Further, the second body <NUM> may include a terminal mount <NUM> for mounting a first terminal <NUM> for electrical connection with the pipe <NUM> and a wire hole <NUM> through which a main body wire passes. The wire hole <NUM> may be covered with a packing (not shown) and the main body wire may pass through the packing. When a suction nozzle connected to the end of an extension pipe connected to the suction unit <NUM> has a driving unit, the first terminal <NUM> functions as a terminal for supplying power to the driving unit.

Alternatively, a nozzle having the driving unit may be connected directly to the suction unit <NUM>, in which the driving unit of the suction nozzle can also be supplied with power from the battery <NUM> through the suction unit terminal.

When the pipe <NUM> is coupled to the main body fastening boss <NUM>, the suction opening <NUM>, the suction guide <NUM>, the main body fastening boss <NUM>, the terminal mount <NUM>, and the wire hole <NUM> inside the second recession 120a are covered with the pipe <NUM>.

The second body <NUM> may further include a second coupling portion <NUM> extending downward from the second body <NUM> on the opposite side to the suction opening <NUM>.

A coupling hole <NUM> in which the first coupling portion <NUM> of the first body <NUM> is inserted may be formed on the second coupling portion <NUM>.

Further, the second body <NUM> may include a wire hole <NUM> through which a main body wire for supplying power to the suction motor <NUM> passes. The wire hole <NUM> may be covered with a packing <NUM> (see <FIG>) and the main body wire may pass through the packing <NUM> (see <FIG>).

The second body <NUM> may further include a connector support <NUM>. The connector support <NUM> may be disposed above the wire hole <NUM>.

Referring to <FIG>, the handle body <NUM> may include a first handle body <NUM> and a second handle body <NUM> coupled to the first handle body <NUM>.

The first handle body <NUM> forms a portion of the first extension <NUM> and a portion of the second extension <NUM>. The second handle body <NUM> forms the other portion of the first extension <NUM> and the other portion of the second extension <NUM>.

That is, when the second handle body <NUM> is coupled to the first handle body <NUM>, the first handle body <NUM> and the second handle body <NUM> form the first extension <NUM> and the second extension <NUM>.

The first handle body <NUM> may form not only the handle <NUM>, but the outer housing <NUM>.

A space <NUM> for receiving the main PCB unit <NUM> may be defined in the first handle body <NUM>. The space <NUM> is a space substantially defined in the second extension <NUM>.

The first handle body <NUM> may include a support <NUM> that supports the main PCB unit <NUM>.

The support <NUM> may include a seat 324a on which the main PCB unit <NUM> is seated, a first rib 324b that supports the first PCB <NUM> on the seat 324a, and a second rib 324c that supports the second PCB <NUM> on the seat 324a.

When the main PCB unit <NUM> is coupled to the first handle body <NUM>, the support rib <NUM> is positioned between the first PCB <NUM> and the second PCB <NUM>. The support rib <NUM> is spaced apart from the first PCB <NUM> and the second PCB <NUM> in order not to damage the main PCB <NUM> when the main PCB unit <NUM> is coupled.

The inclination angle of the inclined surface 326a of the support rib <NUM> may be the same as the inclination angles 343a and 345a of the extensions <NUM> and <NUM> of the PCBs <NUM> and <NUM>.

Accordingly, the inclined surfaces 343a and 345a of the PCBs <NUM> and <NUM> and the inclined surface 326a of the support rib <NUM> can support the power PCB <NUM>.

Obviously, the inclined surfaces 343a and 345a of the PCBs <NUM> and <NUM> may be spaced apart from the power PCB <NUM>, with the power PCB <NUM> in contact with the inclined surface 326a of the support rib <NUM>.

The first handle body <NUM> may further include a fitting rib 326b passing through the power PCB <NUM> to prevent the power PCB <NUM> being in contact with the inclined surface 326a of the support rib <NUM> from moving left and right in <FIG>. Further, a slit <NUM> for passing the fitting rib 326b may be formed in the power PCB <NUM>.

The fitting rib 326b may be formed at the lower portion of the support rib <NUM>. When the power PCB <NUM> is seated on the inclined surface 326a of the support rib <NUM>, the fitting rib 326b is fitted in the slit <NUM>, so it is possible to prevent the power PCB <NUM> from sliding down on the inclined surface 326a of the support rib <NUM> in the process of assembling the power PCB <NUM>.

Accordingly, the user can more conveniently operate the cleaner.

A process of assembling the main PCB unit <NUM> and the power PCB <NUM> is described hereafter.

First, the PCB cover <NUM> is inserted into the space <NUM> of the first handle body <NUM> such that the light transmissive portions <NUM> of the PCB cover <NUM> are inserted into the insertion holes <NUM> of the first handle body <NUM>.

The main PCB assembly is completed by connecting the first PCB <NUM> and the second PCB <NUM> through the PCB connector <NUM> and then the main PCB assembly is inserted into the space between the PCB cover <NUM> and the support <NUM> of the handle body <NUM>.

When the main PCB assembly is inserted, the side portions <NUM> and <NUM> of the PCB cover <NUM> and the first and second ribs 324b and 324c of the support <NUM> guide the main PCB assembly.

When the coupling hook <NUM> of the PCB connector <NUM> is locked to the hook locking rib 325b through the hook hole 325a while the main PCB assembly is inserted into the space <NUM> of the first handle body <NUM>, coupling of the main PCB assembly is completed.

In this state, as in <FIG>, the power PCB <NUM> is seated on the support rib <NUM> and then the power PCB <NUM> may be fixed to the first handle body <NUM> by a fastener.

The power PCB <NUM> is fixed to the first handle body <NUM> substantially at the same height as the main PCB <NUM>.

Next, as in <FIG>, the second handle body <NUM> is coupled to the first handle body <NUM> and then the operation unit <NUM> may be coupled to the second handle body <NUM>.

According to the present invention, the main PCB <NUM> is divided into two PCBs and inserted in the first handle body <NUM>, and the size of the main PCB <NUM> can be reduced.

In particular, the two PCBs are erect in parallel with each other and inserted in the handle body, the size of the main PCB unit <NUM> can be minimized.

Further, since the main PCB assembly can be coupled to the first handle body <NUM> while it is inserted into the space <NUM> of the first handle body <NUM> with the two PCBs connected to the PCB connector <NUM>, the structures for fixing the two PCBs to each other and fixing the two PCBs to the first handle body <NUM> are simple and a user can easily assemble them.

<FIG> is a view after the handle terminal and the main PCB unit are installed in the handle unit according to an embodiment of the present invention and <FIG> is a view when the handle unit according to an embodiment of the present invention is coupled to the main body after being assembled.

Referring to <FIG> and <FIG>, the handle <NUM> can be coupled to the main body <NUM>, with the main PCB unit <NUM>, the operation unit <NUM>, and the handle terminal <NUM> combined with the handle body <NUM>.

The handle unit <NUM> may be slide-coupled to the main body <NUM> without screws. For example, the handle unit <NUM> can be coupled to the main body <NUM> by bringing the handle unit <NUM> in contact with the main body <NUM> and then sliding down the handle unit <NUM>.

A direction in which the handle unit <NUM> is coupled to the main body <NUM> may be referred to as a second coupling direction. The second coupling direction may cross a first coupling direction in which the suction unit <NUM> is coupled to the main body <NUM>. The second coupling direction may be substantially perpendicular to the first coupling direction.

According to the present invention, the handle unit <NUM> is coupled to both of the second body <NUM> of the main body <NUM> and the cover member <NUM>.

The handle unit <NUM> may further include a plurality of handle wires <NUM>, <NUM>, and <NUM>. The handle wires <NUM>, <NUM>, and <NUM> may be connected to the main PCB unit <NUM>.

The main PCB unit <NUM> may be connected to the battery <NUM>. Further, the main PCB unit <NUM> may receive operation signals from the operation unit <NUM>. The main PCB unit <NUM> may supply power to the suction motor <NUM> and/or the first terminal <NUM> or control the intensity of the suction force of the suction motor <NUM> on the basis of the input operation signals.

The handle wires <NUM>, <NUM>, and <NUM> may include first handle wires <NUM> connected to the handle terminal <NUM> to supply power to the first terminal <NUM> and second handle wires <NUM> connected to the handle terminal <NUM> to supply power to the suction motor <NUM>.

In this state, when the handle unit <NUM> is pushed down, the insertion ribs <NUM> of the handle unit <NUM> are brought in contact with the first extensions <NUM> of the handle coupling portions <NUM> through the insertion openings <NUM> and locked to the second extensions <NUM>.

Further, the handle hook <NUM> of the handle unit <NUM> is locked to the handle hook coupling portion <NUM> of the cover body <NUM>. Further, the handle terminal <NUM> is connected to the main body terminal <NUM>. That is, the handle terminal <NUM> is connected to the main body terminal <NUM> when the handle unit <NUM> is pushed down to be coupled to the cover member <NUM>.

The coupling ribs 716a of the cover member <NUM> guide the handle terminal <NUM> and the main body terminal <NUM>. Further, when the handle terminal <NUM> is coupled to the main body terminal, the coupling ribs 716a can cover portions of both sides of the handle terminal <NUM>.

Therefore, according to the present invention, since the handle terminal <NUM> and the main body terminal <NUM> are connected to each other when the handle unit <NUM> is coupled to the cover member <NUM>, the process of combining the handle terminal <NUM> and the main body terminal <NUM> can be removed, so a user can more conveniently combine the terminals.

Since the handle unit <NUM> is slide-coupled to the cover body <NUM> by the insertion ribs <NUM> of the handle unit <NUM> and the handle coupling portions <NUM> of the cover member <NUM>, it is possible to stably combine the handle terminal <NUM> and the main body terminal <NUM>.

In this embodiment, since the battery connection terminal <NUM> passes through the protrusion <NUM> when the protrusion <NUM> is inserted into the receiving portion <NUM>, the receiving portion <NUM> guides the protrusion <NUM> so that the battery connection terminal <NUM> can stably pass through the protrusion <NUM>.

In order to separate the battery <NUM> from the battery housing <NUM>, a user can insert a finger into the space <NUM> defined between the hinge coupling portions <NUM>.

Further, the user can press the first coupling portion <NUM> toward the frame <NUM> with the finger. Accordingly, the first hook <NUM> of the first coupling portion <NUM> is unlocked from the locking rib <NUM>.

Further, the user can unlock the second coupling portion <NUM> from the battery housing <NUM> by operating the second coupling portion <NUM> exposed to the outside of the battery housing <NUM>.

In detail, the user presses the second coupling portion <NUM> toward the frame <NUM>. Accordingly, the second coupling portion <NUM> is bent toward the frame <NUM> by the space between the frame <NUM> and the second coupling portion <NUM>. Therefore, the second hook <NUM> is pulled out of the coupling slot <NUM>.

As a result, the first coupling portion <NUM> and the second coupling portion <NUM> are moved toward each other by a user, whereby they are unlocked.

Accordingly, a user can unlock the first coupling portion <NUM> and the second coupling portion <NUM> using two fingers, so the user can easily separate the battery <NUM> downward from the battery housing <NUM>.

According to the present invention, since the battery <NUM> can be separated from the battery housing <NUM>, it is possible to place only the battery <NUM> on the charging stand to charge it.

<FIG> is a conceptual diagram schematically showing the combination structures of the cleaner of the present invention.

Referring to <FIG>, the present invention may include, as described above, the main body <NUM>, the handle unit <NUM>, and the battery <NUM>.

The cleaner <NUM> of the present invention have largely three combination structures for power supply.

The first combination structure is the structure for combining the battery <NUM> and the handle unit <NUM>. The battery <NUM> is separably coupled to the handle unit <NUM> in the present invention.

When the battery <NUM> is coupled to the handle unit <NUM>, the battery <NUM> is connected to the main PCB unit <NUM>. The battery <NUM> and the handle unit <NUM> are combined by mechanically combining the battery terminal <NUM> and the battery connection terminal <NUM>. Obviously, since the main PCB unit <NUM> is connected to the battery connection terminal <NUM> through wires, when the battery terminal <NUM> and the battery connection terminal <NUM> are combined, they are electrically connected, so the power from the battery <NUM> can be supplied to the main PCB unit <NUM>.

The second combination structure of the present invention is the structure for combining the handle unit <NUM> and the main body <NUM>.

When the handle unit <NUM> is vertically slide-coupled to the main body <NUM>, with the main PCB unit <NUM> connected to the handle terminal <NUM>, the handle terminal <NUM> and the main body terminal <NUM> are mechanically combined. Obviously, when the handle terminal <NUM> and the main body terminal <NUM> are combined, they are electrically connected, so power can be supplied to the main body terminal <NUM> through the handle terminal <NUM> from the main PCB unit <NUM>.

The handle unit <NUM> has the cover coupling portion <NUM> and the cover member <NUM> has the insertion openings <NUM> and the handle hook coupling portion <NUM> for coupling the cover coupling portion <NUM>. Accordingly, the handle unit <NUM> can be stably combined with the cover member <NUM>, and in this process, the handle terminal <NUM> can be accurately coupled to the main body terminal <NUM>. That is, the cover coupling portion <NUM>, the insertion openings <NUM>, and the handle hook coupling portion <NUM> guide the handle terminal <NUM> and the main body terminal <NUM> that are combined with each other, so an assembly error of the handle terminal <NUM> and the main body terminal <NUM> is reduced.

Since the handle unit <NUM> has the body coupling portion <NUM> and the second body <NUM> of the main body <NUM> has the first handle coupling portions 139a and 139b, the handle unit <NUM> can be stably combined with the second body <NUM>, and in this process, the handle terminal <NUM> can be accurately coupled to the main body terminal <NUM>. That is, the body coupling portion <NUM> and the first handle coupling portions 139a and 139b also guide the handle terminal <NUM> and the main body terminal <NUM> that are combined with each other, so an assembly error of the handle terminal <NUM> and the main body terminal <NUM> is reduced.

Further, as described above, the coupling ribs 716a for coupling the main body terminal <NUM> and the terminal support 716c for supporting the bottom of the main body terminal <NUM> are formed on the cover member <NUM>. Accordingly, the main body terminal <NUM> is not pushed down when the handle terminal <NUM> is coupled to the main body terminal <NUM>, so the assembly error of the handle terminal <NUM> and the main body terminal <NUM> is reduced.

The third combination structure of the present invention is the combination structure among the main body wires electrically connected to the main body terminal <NUM>, the suction motor <NUM> in the main body <NUM>, and the first terminal <NUM>. This combination structure is an electrically connected structure positioned in the main body <NUM> and achieved by the main body wires. The power supplied to the main body terminal <NUM> can be finally supplied to the suction motor <NUM> and the first terminal <NUM> by the electrically combined structure.

According to the combination structures of the present invention, air channels are formed only in the main body <NUM> and are not formed in the handle unit <NUM>.

Accordingly, there is no need for a structure for sealing the boundary between the handle unit <NUM> and the main body <NUM> when the handle unit <NUM> is coupled to the main body <NUM>. Therefore, the structure for coupling the handle unit <NUM> to the main body <NUM> is simple and the coupling is easy.

In the present invention, the suction motor <NUM> and the first terminal <NUM> receive power from the battery <NUM>, so they may be called power receiving components.

On the other hand, although the main body terminal <NUM> is mounted on the cover member <NUM> and the handle terminal <NUM> is connected to the main body terminal <NUM> in the embodiments described above, the connecting terminal 349a of the second body of the main body may include not only the signal terminal for transmitting control signals of the suction motor <NUM>, but a power terminal for power supply. Accordingly, the main PCB unit <NUM> may also have the power terminal.
