Patent Description:
A cleaner is a device that performs cleaning by sucking and wiping dust or foreign substances from a region to be cleaned.

Such a cleaner may be classified into a manual cleaner that performs cleaning while a user directly moves the cleaner and an automatic cleaner that performs cleaning while the cleaner is driven by itself. The manual cleaner may be classified into a canister cleaner, an upright cleaner, a handheld cleaner, a stick cleaner, and the like, depending on types of the cleaner.

The above-described cleaner may have a rechargeable battery embedded therein, and the rechargeable battery may supply electric power for operating the cleaner only when being frequently charged. Thus, the cleaner requires a holder that can simultaneously charge the rechargeable battery and hold the cleaner.

Contents of a vacuum cleaner holder are disclosed in <CIT> as the prior art.

The vacuum cleaner holder according to the prior art includes a pedestal for holding a head of a vacuum cleaner to simultaneously charge and hold the vacuum cleaner and a support having charging pins for charging the vacuum cleaner.

The holder of the prior art only serves to seat the cleaner. Therefore, in the case of various accessories such as nozzles to be connected to the cleaner, a user needs to keep them separately. Consequently, a storage space is required, and there is a great fear of loss of accessories. A cleaner holder according to the preamble of claim <NUM> is already known e.g. from <CIT>.

Embodiments provide a cleaner holder capable of storing accessories, such as a water cleaning module, which may be connected to a cleaner, separately from holding the cleaner.

In addition, the predetermined distance may be smaller than a minimum distance between the first extension line drawn along the central axis of the extension tube and the second extension line drawn along the central axis of the stand.

The support body may be positioned above a space formed between the extension tube and the stand.

In further another embodiment, a cleaning unit may include a cleaner and a holder placed on a floor surface to support the cleaner at a predetermined height with respect to the floor surface, wherein the holder may include: a support body for supporting the cleaner; a stand coupled to a lower side of the support body and extending downward; a base coupled to a lower side of the stand and placed on the floor surface; and a cleaning module support coupled to the stand and supporting a cleaning module that is able to be detachably coupled to the cleaner.

The stand may transmit at least a part of the weight of the cleaner to the base in a state in which the cleaner is seated on the support body, and the cleaning module support and the stand may transmit the weight of the cleaning module to the base in a state in which the cleaning module is supported by the cleaning module support.

The cleaner may further include an extension tube, and a suction nozzle detachably coupled to the extension tube.

When the suction nozzle is coupled to the extension tube and the cleaner is seated on the support body in a state in which the extension tube is coupled to the cleaner, the suction nozzle may be seated on the base, and the extension tube and the suction nozzle may transmit a part of the weight of the cleaner to the base.

The cleaning module support may be coupled to the stand between the support body and the base.

When the cleaner is seated on the support body in a state in which the extension tube is coupled to the cleaner, and the cleaning module is supported by the cleaning module support, the cleaning module may be positioned between the extension tube and the stand.

The holder may form an accommodation space for accommodating an auxiliary battery separated from the cleaner. Specifically, the support body may include an accommodation space for accommodating the auxiliary battery separated from the cleaner.

In a state in which the auxiliary battery is accommodated in the support body and the cleaning module is supported by the cleaning module support, the auxiliary battery may overlap the cleaning module in the vertical direction.

When the cleaner is supported to the support body in a state in which the auxiliary battery is accommodated in the support body, the cleaning module is supported by the cleaning module support, and the battery is mounted on the cleaner, the auxiliary battery may be positioned between the battery mounted on the cleaner and the cleaning module.

When the cleaner is supported by the support body in a state in which the battery is mounted on the cleaner, and the cleaning module is supported by the cleaning module support, the battery may overlap the cleaning module in the vertical direction.

In still another embodiment, a cleaner unit may include: a cleaner body provided with a suction motor to provide suction force; a battery mounted on the cleaner body; an auxiliary battery separated from the cleaner body; an extension tube coupled to the cleaner body; a suction nozzle detachably coupled to the extension tube; and a holder on which the auxiliary battery is mounted for charging, the holder supporting the cleaner body at a predetermined height from a floor surface.

The cleaner body may be supported between the battery and the auxiliary battery.

When the cleaner is supported by the holder, the predetermined height may be defined between the height of the battery and the height of the auxiliary battery.

When the cleaner body is supported by the holder, the suction nozzle may be into contact with the upper surface of the base.

The upper surface of the base that is into contact with the suction nozzle may be formed with an inclined surface.

The holder may form an accommodation space for accommodating the auxiliary battery.

When the auxiliary battery is accommodated in the accommodation space, the auxiliary battery may be charged independently of the battery.

When the auxiliary battery is mounted on the holder, the auxiliary battery may be positioned below the battery.

When the cleaner is supported by the support body in a state in which the battery is mounted on the cleaner, the auxiliary battery may be positioned in the vertical direction of the battery.

According to the embodiments of the present disclosure, since it is possible to store accessories such as the water cleaning module which can be coupled to the cleaner separately from mounting the cleaner on the holder, the water cleaning module is less likely to be lost and easy to store.

In addition, according to the present disclosure, the mops attachable to the water cleaning module may be separately stored in a state of being separated from the mop plate, thereby reducing the risk of losing the mops and facilitating the storage of the mops.

Further, according to the present disclosure, since the water discharge hole is formed in the mop storage portion, the phenomenon that the water dropped from the mops is collected and contaminated in the mop storage portion may be prevented.

Further, according to the present disclosure, since the cleaning module is positioned forward of the mops in a state in which the mops are stored in the mop storage portion, the frontward exposure of the mops may be minimized.

Further, since the cleaning module support is coupled to the stand in a state of being positioned below the support body of the holder, the center of gravity of the holder itself may be lowered such that the holder may stably support the cleaner.

<FIG> is a perspective view illustrating a state in which a cleaner is seated on a cleaner holder according to an embodiment of the present disclosure, <FIG> is a side view of the cleaner holder of <FIG>, and <FIG> is an exploded perspective view of the water cleaning module that may be used in connection with the cleaner.

Referring to <FIG>, a cleaner holder <NUM> according to an embodiment of the present disclosure includes a support body <NUM> for supporting a cleaner <NUM>.

The support body <NUM> may support the cleaner <NUM> and charge a battery <NUM> mounted on the cleaner <NUM>.

The cleaner <NUM> may include a cleaner body <NUM> having a suction motor, and a battery housing <NUM> in which the battery <NUM> is accommodated.

An extension tube <NUM> to which a suction nozzle <NUM> is coupled may be coupled to the cleaner body <NUM>. Air and dust may be suctioned through the suction nozzle <NUM> by suction force generated by the suction motor.

In addition, a discharge port through which the suctioned air is discharged via an internal filter may be formed on the front surface of the cleaner body <NUM>.

External air is introduced into the cleaner body <NUM> through the suction nozzle <NUM> and the extension tube <NUM> by suction force generated by the suction motor. The cleaner body <NUM> may include a dust container <NUM> in which dust contained in air introduced through the suction nozzle <NUM> is collected.

Also, the cleaner body <NUM> may include a handle <NUM> that the user can grip.

The handle <NUM> will be described in detail with reference to <FIG>.

The handle <NUM> may extend from one side of the battery housing <NUM> to the front end of the cleaner body <NUM>. For example, the handle <NUM> may extend from the upper end of the battery housing <NUM> in a first direction (e.g., forward), be bent in a second direction (e.g., downward), and extend to the front end of the cleaner body <NUM>.

The handle <NUM> may extend to form a hole into which a user's hand is inserted. That is, the hole may be formed between the handle <NUM> and the dust container <NUM>.

The handle <NUM> may extend in a cylindrical shape having a predetermined radius so that the user can grip the handle <NUM>.

The handle <NUM> may be provided with a finger guide <NUM> that may limit the movement of the hand in a state in which the user grips the handle <NUM>. The finger guide <NUM> may be referred to as a "movement limiting portion".

The finger guide <NUM> may protrude in a direction in which the hole is formed.

For example, the finger guide <NUM> may extend in a vertical direction from the inner circumferential surface of the handle <NUM> defining the hole. The end of the finger guide <NUM> may be spaced apart from the inner circumferential surface of the handle <NUM> in the extending direction of the finger guide <NUM>.

Therefore, in a state in which the user grips the handle <NUM>, some of the fingers may be positioned on one side of the finger guide <NUM>, and the other fingers may be positioned on the other side of the finger guide <NUM>. For example, the finger guide <NUM> may be positioned between the index finger and the middle finger.

Therefore, the user may minimize the force required when the user holds the handle <NUM> to push or pull the cleaner <NUM>.

The support body <NUM> may include a first body <NUM> having a first charging terminal for charging the battery <NUM> mounted on the cleaner <NUM>.

The support body <NUM> may further include a second body <NUM> protruding from the first body <NUM>.

The second body <NUM> may protrude from the front end of the first body <NUM> by a predetermined distance DH. That is, the predetermined distance DH may be understood as a minimum length from the front end of the first body <NUM> to the front end of the second body <NUM>. The second body <NUM> may support a part of the cleaner <NUM>.

In detail, the upper surface of the second body <NUM> may support the cleaner body <NUM>. Accordingly, the cleaner <NUM> may be stably seated on the support body <NUM>. Here, the upper surface of the second body <NUM> may be referred to as a "cleaner support surface". Thus, the predetermined distance DH may be referred to as the length DH of the cleaner support surface.

Meanwhile, the second body <NUM> may define the upper end of the spacing space formed by the extension tube <NUM> and a stand <NUM> described later in the front-rear direction.

That is, according to the second body <NUM> extending forward from the first body <NUM>, it is possible to form the spacing space for storing the accessory to be described later. Thus, the user access to the accessory may be facilitated.

In addition, according to the second body <NUM> defining the bottom surface of the support body <NUM>, the extension tube <NUM> may be coupled to the cleaner body <NUM> without any spatial interference of the support unit <NUM>, which will be described later. Therefore, the user may easily combine or separate the cleaner <NUM> to the holder <NUM> without any spatial interference, thereby improving user convenience.

The cleaner body <NUM> may be seated on the upper surface of the second body <NUM>. In other words, in addition, the support body <NUM> may accommodate an auxiliary battery <NUM> that may be mounted on the cleaner <NUM>. For example, the second body <NUM> may include a second charging terminal for accommodating the auxiliary battery <NUM> and charging the accommodated auxiliary battery <NUM>.

The charging of the cleaner <NUM> by the first charging terminal (charging of the battery <NUM> mounted on the cleaner <NUM>) and the charging of the auxiliary battery <NUM> by the second charging terminal are independently performed.

Specifically, the charging of the cleaner <NUM> and the charging of the auxiliary battery <NUM> may be performed at the same time, or one charging may be charged and then the other charging may be performed. For example, after the battery <NUM> of the cleaner <NUM> is fully charged by the first charging terminal, the charging of the auxiliary battery <NUM> by the second charging terminal may be started.

Extra nozzles <NUM> and <NUM> may be coupled to the support body <NUM>. The extra nozzles <NUM> and <NUM> may be detachable to the cleaner or the like. In general, the cleaner may include a plurality of nozzles <NUM>, <NUM>, and <NUM> that may be replaced with the suction nozzle <NUM>, depending on the purpose.

Therefore, the unused nozzles <NUM>, <NUM>, and <NUM> are disadvantageously inconvenient to store.

However, if the extra nozzles <NUM> and <NUM> are stored in a state of being coupled to the support body <NUM> as in the embodiment of the present disclosure, the risk of loss may be reduced and ease of use may be improved. Here, the unused nozzles, that is, the extra nozzles <NUM> and <NUM>, and the water cleaning module <NUM> to be described later may be referred to as "accessories".

The extra nozzles <NUM> and <NUM> may be coupled to the lower side of the support body <NUM>.

The accessories may be positioned between a lower end S1 of the second body <NUM> and an upper end S2 of the base <NUM>.

The holder <NUM> of the cleaner may further include a support unit <NUM> for supporting the support body <NUM>.

The support unit <NUM> may include a base <NUM> mounted on a floor and a stand <NUM> provided on the base <NUM>.

The stand <NUM> may be coupled to the upper side of the base <NUM> and may extend upward. The stand <NUM> may be detachably coupled to the support body <NUM>.

For example, the lower end of the stand <NUM> may be coupled to the base <NUM>, and the upper end of the stand <NUM> may be coupled to the support body <NUM>. The stand <NUM> may be coupled to the lower side of the first body <NUM>.

The stand <NUM> may be coupled to the first body <NUM> at a position lower than the center of gravity of the support body <NUM>. Although not limited thereto, the center of gravity of the support body <NUM> may be positioned directly above the stand <NUM>.

Therefore, the support body <NUM> may be positioned at a predetermined height on the floor by the stand <NUM>.

The length of the stand <NUM> is longer than the length of the extra nozzles <NUM> and <NUM>. Therefore, the extra nozzles <NUM> and <NUM> are spaced apart from the upper surface of the base <NUM> in a state in which the extra nozzles <NUM> and <NUM> are coupled to the support body <NUM>.

The extra nozzles <NUM> and <NUM> may be disposed at positions F1 and F3 in front of the stand <NUM>.

In other words, the virtual extension lines F1 and F3 extending along the central axes of the extra nozzles <NUM> and <NUM> may be positioned forward of the virtual extension line C2 extending along the central axis of the stand <NUM> and/or the virtual extension line F3 of the module coupling portion <NUM> to be described later.

An extension tube <NUM> of the cleaner <NUM> may be positioned forward of the extra nozzles <NUM> and <NUM>.

In other words, the virtual extension line C1 extending along the central axis of the extension tube <NUM> may be positioned forward of the virtual extension lines F1 and F3 of the extra nozzles <NUM> and <NUM>.

Here, the virtual extension line C1 drawn along the central axis of the extension tube <NUM> may be referred to as a first extension line. The virtual extension line C2 drawn along the central axis of the stand <NUM> may be referred to as a second extension line.

Thus, the extra nozzles <NUM> and <NUM> may be positioned between the first extension line C1 and the second extension line C2.

Further, the extension tube <NUM> may be positioned behind the virtual extension line C3, which is drawn directly downward along the front surface of the cleaner body <NUM>. The extension tube <NUM> may be positioned behind the virtual extension line C5 drawn along the extending direction of the finger guide <NUM> protruding directly downward to the handle <NUM> of the cleaner <NUM>.

Here, the virtual extension line C3, which is drawn directly downward along the front surface of the cleaner body <NUM>, may be referred to as a third extension line. The virtual extension line C5 drawn along the extending direction of the finger guide <NUM> may be referred to as a fourth extension line.

The cleaner holder <NUM> may further include nozzle supports 317a and 318b to which the extra nozzles <NUM> and <NUM> are selectively coupled.

The nozzle supports 317a and 318b may be coupled to at least one of the support body <NUM> or the stand <NUM>. For example, the nozzle supports 317a and 318b may be formed to extend downward from the bottom surface of the support body <NUM>.

The user may attach and detach the respective nozzles <NUM> and <NUM> to and from the nozzle supports 317a and 318b as necessary.

Accordingly, the extra nozzles <NUM> and <NUM> may be easily stored and used, thereby improving user convenience.

In order for the extra nozzles <NUM> and <NUM> to be coupled, the nozzle supports 317a and 318b may be formed in, for example, a cylindrical shape. The nozzle supports 317a and 318b may be fitted to the extra nozzles <NUM> and <NUM>.

The extra nozzles <NUM> and <NUM> may be provided with locking hooks that are movably installed. For example, the locking hooks may be engaged with or disengaged from the nozzle supports 317a and 318b by the operation of the user.

A water cleaning module <NUM> capable of suctioning air and wiping the floor surface by using a mop with water may be detachably coupled to the extension tube <NUM> of the cleaner <NUM>.

For example, the water cleaning module <NUM> may include module housings <NUM> and <NUM>, a coupling tube <NUM> provided in the module housings <NUM> and <NUM>, one or more rotary cleaning portions <NUM> and <NUM> rotatably coupled to the lower sides of the module housings <NUM> and <NUM>, and one or more driving devices <NUM> and <NUM> provided in the module housings <NUM> and <NUM> to drive one or more rotary cleaning portions <NUM> and <NUM>.

The water cleaning module <NUM> may further include a water tank <NUM> that is seated above the module housings <NUM> and <NUM>. Water stored in the water tank <NUM> may be supplied to the rotary cleaning portions <NUM> and <NUM> through the module housings <NUM> and <NUM> via an internal flow path.

The rotary cleaning portions <NUM> and <NUM> may include mops <NUM> and <NUM> and mop plates <NUM> and <NUM> to which the mops <NUM> and <NUM> are attached. The water in the water tank <NUM> may be supplied to the mops <NUM> and <NUM> through the mop plates <NUM> and <NUM>.

The mop plates <NUM> and <NUM> may be coupled to the driving devices <NUM> and <NUM> and rotated below the module housings <NUM> and <NUM>.

The mop plates <NUM> and <NUM> may be provided as a pair. The mops <NUM> and <NUM> may also be provided as a pair. Accordingly, the mops <NUM> and <NUM> may be attached to and detached from the mop plates <NUM> and <NUM>, respectively.

The mops <NUM> and <NUM> may be in contact with the floor surface to clean the floor surface during the rotation process.

When the user couples the suction nozzle <NUM> to the extension tube <NUM> of the cleaner <NUM>, it is possible to carry out cleaning in such a manner that dust on the floor surface is suctioned.

On the other hand, when the suction nozzle <NUM> is separated from the extension tube <NUM> of the cleaner <NUM> and the water cleaning module <NUM> is coupled to the extension tube <NUM>, the suction of the dust on the floor surface and the water cleaning on the floor surface may be performed.

In this manner, any one of the suction nozzle <NUM> and the water cleaning module <NUM> may be selected and coupled to the extension tube <NUM>, and the other one should be stored so as to prevent loss.

In the present embodiment, the suction nozzle <NUM> may be referred to as a "floor cleaning module".

When the cleaner <NUM> is supported by the support body <NUM> in a state in which the suction nozzle <NUM> is coupled to the extension tube <NUM>, the suction nozzle <NUM> may be seated on the upper surface of the base <NUM>.

In detail, the upper surface of the base <NUM> on which the suction nozzle <NUM> is seated forms an inclined surface inclined downward toward the front end.

That is, the front end 210a of the base <NUM> may be formed as an inclined surface to support the suction nozzle <NUM> (see <FIG>).

Due to this, the front end 210a of the base <NUM> may stably support the extension tube <NUM>, and the support body <NUM> may stably support the cleaner body <NUM>.

That is, the cleaner <NUM> may be stably supported by the base <NUM> and the support body <NUM>. As a result, the cleaner <NUM> may be supported at two positions of the holder <NUM>. The two positions may be positioned at the upper and lower sides of the holder <NUM>, respectively, and may be spaced apart from each other. Therefore, the cleaner <NUM> may be stably fixed to the holder <NUM>.

In the present embodiment, in order to store the cleaning module not used, the cleaner holder <NUM> may further include a cleaning module support <NUM> for storing the cleaning module.

In the cleaner holder <NUM> the present embodiment, there is an extra space between the extension tube <NUM> and the stand <NUM> and between the extra nozzles <NUM> and <NUM> and the base <NUM>.

The extra space may define the front-rear direction by the first extension line C2 and the second extension line C2. In detail, the first extension line C2 may be spaced apart from the second extension line C2 by a predetermined length DL. Here, the predetermined length DL may be understood as a minimum distance between the first extension line C1 and the second extension line C2.

The minimum distance DL may be longer than the length DH of the cleaner support surface described above (see <FIG>).

Accordingly, in order to prevent the volume of the holder <NUM> from increasing, to facilitate storage, and to allow the user to easily access the stored cleaning module, the cleaning module may be supported on the cleaning module support <NUM> in a state of being positioned in the extra space.

In addition, the cleaning module support <NUM> may be positioned on a virtual straight line L passing through the extension tube <NUM> and the stand <NUM>. The cleaning module may be supported by the cleaning module support <NUM>.

That is, the virtual straight line L may pass through the extension tube <NUM>, the stand <NUM>, and the cleaning module support <NUM>.

Here, the virtual straight line L may pass through the extension tube <NUM> and the stand <NUM> at the same height from the ground. In detail, the virtual straight line L may be drawn to pass through one point of the second extension line C2 positioned at the same height as one point of the first extension line C1.

That is, the virtual straight line L may be understood as a straight line passing through the central axis of the extension tube <NUM> and the central axis of the stand <NUM> at the same height from the ground.

Since the cleaning module support <NUM> is positioned on the virtual straight line L, the center of the cleaning module coupled to the extension tube <NUM>, the stand <NUM>, and the cleaning module support <NUM> may be aligned in the front-rear direction.

Due to this, since the cleaning module coupled to the cleaning module support <NUM> is arranged to overlap the extension tube <NUM> or the stand <NUM> in the front-rear direction, it is possible to provide a clear appearance when the user views the front of the holder <NUM>. In addition, there is an advantage that the size of the cleaner <NUM> and the holder <NUM> occupying a space may be minimized.

In addition, when expressed with reference to the cleaning module support <NUM>, the cleaning module support <NUM> may be positioned at a height H2 lower than the heights H1 and H3 of the extra nozzles <NUM> and <NUM> in the extra space. The cleaning module support <NUM> may be positioned (F2) behind the extra nozzles <NUM> and <NUM>.

Hereinafter, an example in which the water cleaning module is supported by the cleaning module support <NUM> will be described.

<FIG> is a view illustrating a process of assembling a cleaner holder according to an embodiment of the present disclosure, <FIG> is a front view of a cleaning module support according to an embodiment of the present disclosure, <FIG> is a side view of the cleaning module support according to an embodiment of the present disclosure, <FIG> is a view illustrating a state in which a mop storage portion is coupled to a stand coupling portion according to an embodiment of the present disclosure, and <FIG> is a plan view illustrating a state in which the mop storage portion is coupled to the stand coupling portion according to the embodiment of the present disclosure.

Referring to <FIG>, the cleaning module support <NUM> according to the present embodiment may be coupled to surround the stand <NUM>.

For example, the cleaning module support <NUM> may include a stand coupling portion <NUM> coupled to the stand <NUM> so as to pass therethrough. The stand coupling portion <NUM> may include a hollow <NUM> through which the stand <NUM> passes. That is, the cleaning module support <NUM> may be coupled to or separated from the stand <NUM> through the hollow <NUM>.

The stand coupling portion <NUM> may be seated in a neck portion <NUM> of the base <NUM> in a state in which the stand <NUM> passes through the hollow <NUM> of the stand coupling portion <NUM>. The stand <NUM> may be coupled to the neck portion <NUM> of the base <NUM>.

A module coupling portion <NUM> for coupling the water cleaning module <NUM> may be provided on the front surface <NUM> of the stand coupling portion <NUM>. Each of the water cleaning module <NUM> and the floor cleaning module is provided with a coupling rib <NUM> to be coupled to the module coupling portion <NUM>.

The module coupling portion <NUM> may protrude forward from the front surface <NUM> of the stand coupling portion <NUM>. Here, the module coupling portion <NUM> may be positioned (F3) behind the positions F1 and F3 to which the extra nozzles <NUM> and <NUM> are coupled.

The module coupling portion <NUM> may include a pair of extension portions <NUM> protruding from the front surface <NUM> of the stand coupling portion <NUM> and spaced apart in the horizontal direction, and a coupling portion <NUM> connecting the front ends of the pair of extension portions <NUM>. A space in which the coupling rib <NUM> is disposed may be formed by the pair of extension portions <NUM> and the coupling portion <NUM>.

The coupling portion <NUM> may be provided with a slot <NUM> for accommodating a part of the coupling rib <NUM> so as to couple the coupling rib <NUM>.

Therefore, a part of the coupling rib <NUM> may be disposed in the slot <NUM>, and the other part thereof may be disposed in the space formed by the pair of extension portions <NUM> and the coupling portion <NUM>.

The cleaning module support <NUM> may further include a mop storage portion <NUM> for independently storing the mops <NUM> and <NUM>. The mop storage portion <NUM> may be integrally formed with the stand coupling portion <NUM>, or may be detachably coupled to the stand coupling portion <NUM>.

Hereinafter, an example in which the mop storage portion <NUM> is detachably coupled to the stand coupling portion <NUM> will be described.

The mop storage portion <NUM> may be coupled to, for example, the rear surface <NUM> of the stand coupling portion <NUM>. That is, the mop storage portion <NUM> may be positioned on the opposite side of the module coupling portion <NUM> with respect to the stand <NUM>.

When the mop storage portion <NUM> is coupled to the rear surface <NUM> of the stand coupling portion <NUM>, the mops <NUM> and <NUM> are positioned behind the stand <NUM>.

Accordingly, when the water cleaning module <NUM> is coupled to the module coupling portion <NUM>, the mops <NUM> and <NUM> may be covered by the water cleaning module <NUM>, thereby minimizing the exposure to the outside.

Since the mops <NUM> and <NUM> are formed in a disk shape, the mop storage portion <NUM> may be formed in a substantially semicircular shape in a vertical section so as to store the diskshaped mops <NUM> and <NUM>.

The mop storage portion <NUM> may include an upper surface opening <NUM>, and the lower surface thereof for supporting the mops <NUM> and <NUM> may be rounded.

Therefore, when the mops <NUM> and <NUM> are stored in the mop storage portion <NUM>, the lower sides of the mops <NUM> and <NUM> are supported on the rounded surface, and a part of the mops <NUM> and <NUM> may protrude upward from the mop storage portion <NUM>.

Accordingly, the user may take out the mops <NUM> and <NUM> by holding the portion of the mop storage portion <NUM> protruding upward from the mop <NUM> and <NUM>.

In addition, a slot <NUM> in which a user's finger is placed may be formed in the mop storage portion <NUM> such that the user may easily hold the mops <NUM> and <NUM>. The slot <NUM> may be formed as a portion of the upper surface of the mop storage portion <NUM> is recessed so as to be rounded downward.

When the mops <NUM> and <NUM> are stored in the mop storage portion <NUM> in a state in which the mops <NUM> and <NUM> keep water, the water of the mops <NUM> and <NUM> may be stored on the bottom of the mop storage portion <NUM>. In this case, the mops <NUM> and <NUM> may be contaminated by the water, and bacteria may be generated.

Therefore, one or more water discharge holes <NUM> for discharging water from the mops <NUM> and <NUM> may be formed on the lower surface of the mop storage portion <NUM>.

A pair of first coupling ribs <NUM> and <NUM> may provided on the stand coupling portion <NUM> so as to couple the mop storage portion <NUM> to the stand coupling portion <NUM>, and the mop storage portion <NUM> may be provided with a pair of second coupling ribs <NUM> and <NUM> so as to couple with the first coupling ribs <NUM> and <NUM>.

The pair of first coupling ribs <NUM> and <NUM> may be formed so as to be spaced apart in the horizontal direction and have a substantially "<IMG>"-shaped horizontal cross section.

Further, the pair of second coupling ribs <NUM> and <NUM> may be formed so as to be spaced apart in the horizontal direction, and may have a substantially "<IMG>"-shaped horizontal cross section. The first coupling ribs <NUM> and <NUM> and the second coupling ribs <NUM> and <NUM> may be formed in the opposite shapes.

Although not illustrated, the lower ends of the pair of first coupling ribs <NUM> and <NUM> may be provided with support surfaces for supporting the lower ends of the second coupling ribs <NUM> and <NUM>.

Therefore, when the mop storage portion <NUM> is moved downward in a state in which the mop storage portion <NUM> is positioned above the first coupling ribs <NUM> and <NUM>, the second coupling ribs <NUM> and <NUM> are engaged with the first coupling ribs <NUM> and <NUM> such that the mop storage portion <NUM> is coupled to the stand coupling portion <NUM>.

Both ends of the stand coupling portion <NUM> may be spaced apart from each other when viewed from the above. That is, the space portion <NUM> may be formed between both ends of the stand coupling portion <NUM>. The stand coupling portion <NUM> may be elastically deformed by the space portion <NUM>.

The first coupling ribs <NUM> and <NUM> may be formed at both ends of the stand coupling portion <NUM>.

When the interval between the pair of first coupling ribs <NUM> and <NUM> is formed to be somewhat larger than the interval between the second coupling ribs <NUM> and <NUM>, the pair of first coupling ribs <NUM> and <NUM> are elastically deformed to accumulate the elastic force while the second coupling ribs <NUM> and <NUM> are coupled to the first coupling ribs <NUM> and <NUM>. Therefore, the coupling force between the first coupling ribs <NUM> and <NUM> and the second coupling ribs <NUM> and <NUM> may be increased.

In addition, the stand coupling portion <NUM> may be provided with a limiting rib <NUM> that limits upward movement of the mop storage portion <NUM> in a state in which the second coupling ribs <NUM> and <NUM> are coupled to the first coupling ribs <NUM> and <NUM>. In the limiting rib <NUM>, at least a part of the second coupling ribs <NUM> and <NUM> may be overlapped in the vertical direction.

According to the proposed embodiment, since it is possible to store accessories such as the water cleaning module which can be coupled to the cleaner separately from mounting the cleaner on the holder, the water cleaning module is less likely to be lost and easy to store.

Meanwhile, in the present embodiment, the weight of the cleaner <NUM> is not only supported by the support body <NUM> but also supported by the base <NUM>.

That is, the weight of the cleaner <NUM> is not only transmitted to the support unit <NUM> (finally, the base <NUM>) through the support body <NUM> but also transmitted to the base <NUM> that supports the suction nozzle <NUM>. That is, a part of the weight of the cleaner <NUM> may be transmitted to the base <NUM> through the extension tube <NUM> and the suction nozzle <NUM>.

In addition, the load of the auxiliary battery <NUM> separated from the cleaner <NUM> and accommodated in the second body <NUM> may also be transferred to the base <NUM>.

In addition the weight of the water cleaning module <NUM> may be transmitted to the base <NUM> through the cleaning module support <NUM> and the stand <NUM>.

When the cleaner <NUM> on which the battery <NUM> is mounted is supported by the second body <NUM>, the battery <NUM> of the cleaner <NUM> may overlap the auxiliary battery <NUM> in the vertical direction C4. Referring to <FIG>, the auxiliary battery <NUM> may be spaced apart from the battery <NUM> in the vertical direction.

In a state in which the auxiliary battery <NUM> is accommodated in the support body <NUM> and the water cleaning module <NUM> is mounted on the cleaning module support <NUM>, the auxiliary battery <NUM> may overlap the water cleaning module <NUM> in the vertical direction.

In detail, referring to <FIG>, the center O1 of the auxiliary battery <NUM> and the center O1 of the water cleaning module <NUM> may be spaced apart from each other in the vertical direction. The water cleaning module <NUM> may be positioned directly below the auxiliary battery <NUM> (see a virtual line O1-O2).

The auxiliary battery <NUM> may be positioned between the battery <NUM> and the water cleaning module <NUM>.

Meanwhile, the cleaner body <NUM> may be positioned between the battery <NUM> and the auxiliary battery <NUM>.

As described above, the cleaner body <NUM> can be supported by the support body <NUM>. When the cleaner <NUM> equipped with the battery <NUM> is supported by the second body <NUM>, the cleaner body <NUM> may be supported to be positioned at a height H4-H5 between the battery <NUM> and the auxiliary battery <NUM>.

In addition, in a state in which the cleaner <NUM> equipped with the battery <NUM> is supported by the second body <NUM> and the water cleaning module <NUM> is mounted on the cleaning module support <NUM>, the battery <NUM> of the cleaner <NUM> may overlap the water cleaning module <NUM> in the vertical direction.

That is, the battery <NUM> may be disposed between the first extension line C1 and the second extension line C2. Therefore, the water cleaning module <NUM> disposed below the support body <NUM> may overlap the battery <NUM> in the vertical direction.

According to the present embodiment, since the components having the weights are arranged so as to overlap each other in the vertical direction in a state of being mounted on or supported by the holder <NUM>, the horizontal movement of the center of gravity of the holder <NUM> on which the components are mounted may be minimized, thereby maintaining the holder <NUM> in a stable state.

Further, since the cleaning module support <NUM> is coupled to the stand <NUM> in a state of being positioned below the support body <NUM>, the center of gravity of the holder <NUM> itself may be lowered such that the holder <NUM> may stably support the cleaner <NUM>.

In the present specification, the cleaner <NUM> and the holder <NUM> may be collectively referred to as a "cleaner unit".
