Description

Cleaner {CLEANER}

The present invention relates to a vacuum cleaner having a hygienically manageable cleaning module.

The vacuum cleaner is a device that performs a vacuum cleaning function for collecting dust and foreign matter from the sucked air, or a function for cleaning a rag through a mop.

The cleaner sucks in dust and air at the same time and separates the dust from the inhaled air. The dust separated from the air is collected in the dust collecting device, and the air is discharged to the outside of the cleaner. Inevitably dust accumulates in the vacuum cleaner as well as in the dust collector.

Therefore, it is necessary to manage the cleaner in order to clean the cleaner and maintain the cleaning performance. The management of the cleaner refers to the periodic discharge of the dust collected in the dust collecting device, the dust collecting device, and the removal of accumulated dust in various places of the vacuum cleaner.

To manage the cleaner, the parts of the cleaner must be removed from the cleaner body. However, in this process, the user must inevitably touch the parts of the cleaner by hand, and there is a fear that accumulated dust in the cleaner may be touched by hand. There is a sanitary problem when the user touches the dust with his or her hands.

For example, in order to pull out the agitator from the cleaner head disclosed in Korean Patent Laid-Open Publication No. 10-2015-0038598 (Apr. 20, 2014), the cap is turned by using an I-shaped tool and the agitator is hand- I have to grab it. At this time, since the user has to hold the agitator by hand, the structure disclosed in the above publication is hygienically problematic.

Also, the structure disclosed in the above-mentioned patent publication can be pointed out as a disadvantage in that an I-shaped tool is required to open the cap. Further, when the edge data is taken out by holding one edge of the edge data, the edge data may be inclined with respect to the direction of pulling out, so that dust adhering to the edge data may be adhered to the housing or fall on the bottom.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a cleaning machine according to the present invention will be described in detail with reference to the drawings. In the present specification, the same reference numerals are given to the same components in different embodiments, and the description thereof is replaced with the first explanation. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 1 is a perspective view showing an example of a vacuum cleaner according to the present invention, and FIG. 2 is a side view of the vacuum cleaner shown in FIG. 1.

In this figure, an example of a vacuum cleaner is shown, in which a robot cleaner 100 for suctioning dust on the floor while traveling in a certain area by itself is shown. However, the present invention can be applied not only to the robot cleaner 100 but also to general vacuum cleaners such as a canister type and an upright type.

The robot cleaner 100 may be configured to perform not only a function of sucking dust on the floor but also a function of mopping the floor. For this purpose, the robot cleaner 100 includes a cleaner main body 110 and a cleaning module 120.

The cleaner main body 110 forms an appearance of the robot cleaner 100. The vacuum cleaner main body 110 includes various components including a control unit (not shown) for controlling the robot cleaner 100.

In this figure, the cleaner main body 110 includes a main housing 111 and a cleaning module housing 112. The cleaning module housing 112 is coupled to the main housing 111 in a protruding manner.

The main housing 111 includes a main printed circuit board 113 (see FIG. 12) constituting a control unit, and the dust container 170 is coupled to the main housing 111. Inside the main housing 111, a suction motor for sucking dust, a driving motor for rotating a cleaning module to be described later, and the like may be mounted.

The cleaning module housing 112 is formed with a module mounting portion 110a to which the cleaning module 120 is detachably coupled. However, the present invention is not limited thereto. The cleaner main body 110 may be formed only of the main housing 111. In this case, the module mounting portion 110a may be formed in the main housing 111. [

The cleaner main body 110 may be provided with a bumper switch 112a for detecting a physical collision. The bumper switch 112a may include a bumper member 112a 'which is moved inward by a physical collision with an obstacle and a switch 112a "which is pressed when the bumper member 112a' is moved inward.

In this figure, it is shown that the bumper switch 112a is provided in the cleaning module housing 112. The bumper switch 112a is disposed on the front surface of the cleaning module housing 112, and may be disposed on both sides of the front surface as well as on the front surface.

The cleaner main body 110 is provided with a wheel for traveling. The wheels may be provided on both left and right sides of the cleaner body 110, respectively. The cleaner body 110 can be moved forward or backward, left or right, or rotated by the wheel.

For example, when the robot cleaner 100 has an autonomous running function, the wheel may be configured as a driving wheel 161 that is rotated by receiving a driving force from the driving motor. In another example, if the cleaner main body 110 is moved by a user's operation, the wheel may be configured to have only a rolling function for a conventional floor.

The cleaner main body 110 may further include an auxiliary wheel 162. The auxiliary wheel 162 supports the cleaner main body 110 together with the driving wheel 161 and assists the running of the robot cleaner 100 by the driving wheel 161.

As shown, the auxiliary wheel 162 may be mounted to at least one of the main housing 111 and the cleaning module housing 112. For example, when the cleaning module housing 112 is disposed in a protruding form from the main housing 111, the auxiliary wheel 162 described above may be used not only for the main housing 111, And may also be provided in the cleaning module housing 112.

The cleaning module 120 is configured to clean the floor. Dust and foreign substances in the air sucked through the cleaning module 120 are filtered and collected in the dust container 170. The air separated from the dust and foreign matter is discharged to the outside of the cleaner main body 110. An intake passage (not shown) for guiding the flow of air from the module mounting portion 110a to the dust container 170 may be formed in the cleaner main body 110. [ An exhaust passage (not shown) for guiding the flow of air from the dust container 170 to the outside of the cleaner main body 110 may be formed in the cleaner main body 110.

The cleaning module 120 may optionally include different types of cleaning members. The cleaning member refers to an agitator, a brush, a rag or a mop. The type of the cleaning module 120 can be classified according to the type of the cleaning member.

For example, the cleaning module 120 having a brush may be divided into a brush module, and the cleaning module 120 having a mop may be divided into a mop module. Either the brush module or the mop module may be detachably coupled to the module mounting portion 110a. For example, the user may replace the cleaning member or replace the cleaning module 120 according to the purpose of cleaning.

The kind of the cleaning member is not limited to the brush or the mop. Accordingly, a cleaning module having different types of cleaning members can be generalized to be called a first type cleaning module and a second type cleaning module. The first cleaning module includes a first cleaning member and the first cleaning member may be, for example, a brush. Similarly, the second type cleaning module includes a second type cleaning member, and the second type cleaning member may mean a mop or the like in addition to the brush.

The dust container 170 may be provided with at least one of a filter and a cyclone for filtering dust and foreign matter in the air.

The robot cleaner 100 may include a dust container case 180 covering the dust container 170. [ The dust container 170 can be prevented from being separated from the cleaner main body 110 by the dust container case 180 when the dust container case 180 is disposed to cover the upper surface of the dust container 170. [

Referring to FIG. 2, the dust bin cover 180 is hinged to the cleaner body 110 to be rotatable. The dust container cover 180 may be fixed to the dust container 170 or the cleaner body 110 to cover the upper surface of the dust container 170.

When the robot cleaner 100 has an autonomous running function like a robot cleaner, the cleaner main body 110 may be provided with a sensing unit 190 for sensing a surrounding situation. The control unit can sense an obstacle, detect a land feature, or generate a map of a running area through the sensing unit 190. [

FIG. 3 is a perspective view showing the cleaning module housing 112 separated from the main housing 111 shown in FIG. 4 is a cross-sectional view (on the line A-A in Fig. 3) of the cleaning module housing 112 and the cleaning module 120 shown in Fig.

The cleaning module housing 112 has a module mounting portion 110a on the inner side thereof. The cleaning module housing 112 surrounds the cleaning module 120 to protect the cleaning module 120 mounted on the module mounting portion 110a.

The cleaning module housing 112 may be configured to extend laterally. Here, the left and right indicate a direction set on the basis of when the robot cleaner 100 is viewed from the front. The front of the cleaning module housing 112 indicates the direction in which the bumper switch 112a is installed.

At least a portion of the cleaning module housing 112 may be formed as a transparent member 112b to visually expose the cleaning module 120 mounted therein. In FIG. 3, the portion of the cleaner facing the user's eyes is made of a transparent material. Accordingly, the cleaning module 120 mounted on the module mounting portion 110a of the cleaning module housing 112 is visually exposed to the outside, and the user can visually grasp the state of the cleaning module 120. [

A connection channel 112c is formed in the cleaning module housing 112. The connection channel 112c corresponds to a path through which the dust sucked by the suction force provided by the suction motor moves from the cleaning module housing 112 to the main housing 111. [ The connection passage 112c is connected to the intake passage of the main housing 111 described in FIG. Therefore, the air and the dust sucked through the bottom of the cleaning module housing 112 flows into the intake passage through the connection passage 112c.

The protrusion 112c 'may be formed on the outer surface of the connection channel 112c. In the cleaning module housing 112, a locking protrusion corresponding to the protrusion 112c 'is formed. When the cleaning module housing 112 is coupled to the main housing 111, the connection passage 112c is inserted into the main housing 111, and the protrusion 112c 'is engaged with the locking protrusion.

The cleaning module housing 112 may have a position fixing portion 112d. The position fixing portion 112d may be formed on both sides of the connection passage 112c and may protrude from the cleaning module housing 112. [ The main housing 111 is formed with a position fixing groove (not shown) corresponding to the position fixing portion 112d. When the cleaning module housing 112 is coupled to the main housing 111, the position fixing portion 112d is inserted into the position fixing groove.

Referring to FIG. 4, the cleaning module 120 is mounted on the module mounting portion 110a of the cleaning module housing 112. The cleaning module 120 includes a holder 121 and a cleaning member 122.

The holder 121 is configured to rotatably support the cleaning member 122. Although not shown in FIG. 4, the holder 121 is coupled to both ends of the cleaning member 122, so that the holder 121 and the cleaning member 122 are relatively rotatably coupled.

The cleaning member 122 is rotatable around a rotation axis extending in the left-right direction. In FIGS. 3 and 4, an example of the cleaning member 122 is shown in which the agitator is rotatably mounted around the rotation shaft.

Reference numeral 112e denotes a first side cover, 121a denotes a second side cover, and 121b denotes a hook operating portion, which will be described later.

FIG. 5 is a perspective view showing the cleaning module 120 being inserted or withdrawn from the cleaning module housing 112. FIG.

The cleaning module 120 is detachably mounted on the module mounting portion 110a through one side of the cleaner main body 110. [ 5, the cleaning module 120 is inserted into or removed from the module mounting portion 110a through one side of the cleaning module housing 112. As shown in FIG. Here, one side of the cleaning module housing 112 refers to one of left and right ends of the cleaning module housing 112.

The cleaning module housing 112 has a first side cover 112e and the holder 121 has a second side cover 121a. The first side cover 112e is disposed at a position facing one end of the cleaning member 122 mounted on the module mounting portion 110a. The second side cover 121a is disposed at a position facing the other end of the cleaning member 122 coupled to the holder 121. [ The first side cover 112e and the second side cover 121a may have a shape symmetrical to each other.

The cleaning module housing 112 may be formed to surround the rim of the second side cover 121a in a state where the cleaning module 120 is coupled to the cleaning module housing 112. [ Also, a sealing member (not shown) may be coupled to the rim of the second side cover 121a. This is a structure for preventing dust from leaking between the cleaning module housing 112 and the second side cover 121a.

The cleaning module 120 is detachably mounted on the module mounting portion 110a through one side of the cleaning module housing 112. [ The second side cover 121a is provided with a hook operating part 121b and the cleaning module 120 is detached from the cleaning module housing 112 by an operation applied to the hook operating part 121b. When the cleaning module 120 is pulled out while the cleaning module 120 and the cleaning module housing 112 are disengaged, the cleaning module 120 is taken out of the module mounting portion 110a.

When the cleaning module 120 is pulled out of the cleaning module housing 112, the second side cover 121a is also detached from the cleaning module housing 112, and the inner cover (not shown) disposed inside the second side cover 121a 112f are exposed. The inner cover 112f is provided with a cleaning module insertion hole 112g corresponding to the module mounting portion 110a and the cleaning module 120 is inserted into the module mounting portion 110a through the cleaning module insertion hole 112g, And is drawn out from the mounting portion 110a. The second side cover 121a and the inner cover 112f are formed to be mutually engageable, and this structure will be described later with reference to Fig.

The holder 121 is linearly inserted into the module mounting portion 110a or drawn out from the module mounting portion 110a along the lateral direction of the cleaner main body 110. [ Referring to FIG. 5, it can be seen that the holder 121 is linearly inserted or drawn along the lateral direction (left-right direction) of the cleaning module housing 112.

The cleaning member 122 is supported by the holder 121 to be inserted or withdrawn together with the holder 121 when the holder 121 is inserted or withdrawn. However, the cleaning member 122 is not simply mounted on the holder 121, but is rotatably supported by the holder 121. The outer circumferential surface of the cleaning member 122 is spaced from the holder 121. When only both ends of the cleaning member 122 are supported by the holder 121, the cleaning member 122 is rotatable relative to the holder 121. [

Referring to FIG. 5, an example of the cleaning member 122 is shown in which an agitator 122b is coupled to the outer circumferential surface of the rotation rod 122a. If the outer circumferential surface of the rotation bar 122a contacts the inner surface of the module mounting portion 110a, the rotatable region of the agitator 122b can not be secured. Therefore, the rotation bar 122a is separated from the inner surface of the module mounting portion 110a .

When the agitator 122b comes into contact with the inner surface of the module mounting portion 110a, the suctioned dust may not be sucked into the entrance of the module mounting portion 110a, It is preferable to be spaced from the inner side. When the rotation bar 122a and the agitator 122b are separated from the inner side surface of the module mounting portion 110a, the inner side surface of the module mounting portion 110a is positioned outside the rotation radius of the rotation rod 122a and the agitator 122b do. The dust adhered to the agitator 122b can be prevented from being transferred to the module mounting portion 110a if the inner surface of the module mounting portion 110a is disposed outside the rotation radius of the cleaning member 122. [

When the inner surface of the module mounting portion 110a is disposed outside the rotational radius of the cleaning member 122, the inner surface of the cleaning member 122 and the module mounting portion 110a are not in contact with each other during the drawing process of the cleaning module 120 do. The holder 121 is linearly drawn along the lateral direction of the cleaning module housing 112 and the cleaning member 122 is linearly drawn along the holder 121. [

If the cleaning member 122 is not supported by the holder 121, the cleaning member 122 tilts in the process of withdrawing the cleaning member 122, and the cleaning member 122 is moved to the module mounting portion 110a As shown in Fig. Accordingly, the dust on the cleaning member 122 may be transferred to the inner surface of the module mounting portion 110a, or may fall on the floor. However, the present invention can overcome this concern. This is because the cleaning member 122 maintains a state away from the inner surface of the module mounting portion 110a in the process of removing the cleaning module 120 from the cleaning module housing 112. [

Reference numeral 112f1 denotes a projection insertion hole, and reference numerals 112f2 and 112f3 denote hook insertion insertion holes, which will be described later.

Fig. 6 is a perspective view showing the holder 121. Fig.

As shown in FIG. 6, the holder 121 may include a rotation driving unit 130. The rotation driving unit 130 rotates the cleaning member 122 around the rotation axis extending along the insertion direction or the drawing direction of the cleaning module 120 mounted on the module mounting unit 110a And transmits driving force.

When the rotation driving part 130 is provided in the holder 121, the rotation driving part 130 is inserted into the module mounting part 110a together with the holder 121 or drawn out from the module mounting part 110a. Therefore, the rotation driving unit 130 and the cleaning member 122 are already coupled before the cleaning module 120 is inserted into the module mounting unit 110a.

However, the rotation driving unit 130 does not necessarily have to be provided in the holder 121. For example, the rotation driving unit 130 may be provided inside the first side cover 112e described in FIG. In this case, even if the holder 121 is drawn out from the module mounting portion 110a, the rotation driving portion 130 is not drawn out from the module mounting portion 110a. Further, the cleaning member 122 is inserted into the module mounting portion 110a, and is engaged with the rotation driving portion 130 only.

In any case, in a state in which the cleaning module 120 is mounted on the module mounting portion 110a, the rotation driving portion 130 is disposed on one side of the module mounting portion 110a, and the cleaning member 122 is rotated from the rotation driving portion 130 And is rotated by the provided driving force.

It is also possible to provide two rotation driving units 130. [ For example, one of the rotation driving units may be provided in the holder 121, and the other rotation driving unit may be provided inside the first side cover 112e. In this case, the two rotation driving units 130 are disposed on one side and the other side of the module mounting unit 110a, respectively, and are arranged to face each other. The rotation driving part provided in the holder 121 can be separated from the cleaning module housing 112 along the holder 121 and the position of the rotation driving part provided inside the first side cover 112e can be fixed.

The holder 121 includes a support portion 121c and connection portions 121d1, 121d2, and 121d3.

The support portion 121c is configured to support the cleaning member 122 together with the rotation driving portion 130. [ And a structure for supporting the cleaning member 122. Referring to FIG. 6, the support portion 121c is disposed to face the rotation driving portion 130.

The support portion 121c is required even when two rotation drive portions 130 are provided. The rotation driving part 130 provided inside the first side cover 112e is engaged with the cleaning member 122 only when the cleaning module 120 is mounted on the module mounting part 110a. If there is no supporting portion 121c, there is a problem that the cleaning member 122 is inserted while being inclined during the process of inserting the cleaning module 120 into the module mounting portion 110a.

The support portion 121c surrounds one end of the cleaning member 122 to rotatably support the cleaning member 122. [ For example, the supporting portion 121c has a hole 121c ', and one end of the cleaning member 122 can be inserted into the hole 121c'. In this case, the cleaning member 122 may be rotated in a region defined by the hole 121c 'of the supporting portion 121c.

The hole 121c 'of the support portion 121c may be formed as a long hole. When the support portion 121c is provided with a long hole, the cleaning member 122 coupled to the support portion 121c can move up and down. For example, in the case of cleaning a subject having a non-uniform height such as a carpet, it is more preferable that the cleaning member 122 is moved up and down to perform cleaning. The long holes are not necessarily formed in the vertical direction, but may be formed to be inclined.

The first connection part 121d1 and the second connection part 121d2 are spaced apart from each other to connect the rotation driving part 130 and the support part 121c. The first connection portion 121d1 is disposed in front of the cleaning member 122 and the second connection portion 121d2 is disposed behind the cleaning member 122 when the cleaning member 122 is coupled to the holder 121. [ The cleaning member 122 is exposed to the space between the first connection portion 121d1 and the second connection portion 121d2 so as to be spaced apart from each other to clean the floor.

The holder 121 may further include a plurality of third connection portions 121d3 that are spaced apart from each other.

The plurality of third connection portions 121d3 extend along a direction intersecting the extension direction of the first connection portion 121d1 and the second connection portion 121d2 and connect the first connection portion 121d1 and the second connection portion 121d2 . The connection strength between the first connection portion 121d1 and the second connection portion 121d2 can be secured by the plurality of third connection portions 121d3. The cleaning member 122 may be exposed to the lattice space defined by the first connection part 121d1, the second connection part 121d2 and the third connection part 121d3 to clean the floor.

The second side cover 121a may be formed of a plurality of members. In Fig. 6, the second side cover 121a is formed of three members.

The first member 122a1 is disposed at a position facing the inner cover 112f of the cleaning module housing 112 shown in Fig. And the second member 122a2 is disposed above or below the first member 122a1. In Fig. 6, the second member 122a2 is disposed below the first member 122a1. Finally, the third member 122a3 is disposed outside the first member 122a1 and the second member 122a2. Since the third member 122a3 has a shape corresponding to the first side cover 112e, the third member 122a3 forms an outer appearance corresponding to the first side cover 112e. When the first member 122a1 and the second member 122a2 are also coupled to each other, they have a shape corresponding to the third member 122a3.

The first member 122a1 has a through-hole 121a1 'formed therein. The inner cover 112f of the cleaning module housing 112 is formed with a projection insertion groove or projection insertion hole 112f1 (see FIG. 5) corresponding to the projection insertion hole 121a1 '. The third member 122a3 has a projection 121a3 '. When the first member 122a1 and the third member 122a3 are coupled to each other, the protrusion 121a3 'of the third member 122a3 protrudes through the protrusion through hole 121a1' of the first member 122a1. When the cleaning module 120 is coupled to the cleaning module housing 112, the protrusion 121a3 'of the third member 122a3 is inserted into the protrusion insertion hole 112f1 (see FIG. 5) of the inner cover 112f, . The position of the second side cover 121a can be fixed by the projection insertion structure.

Hereinafter, with reference to FIGS. 5 to 7B, a description will be given of a coupling and disengagement structure of the cleaning module 120 and the cleaning module housing 112. FIG. FIGS. 7A and 7B are conceptual diagrams illustrating a process of disconnecting the cleaning module 120 from the cleaning module housing 112 (corresponding to the line B-B in FIG. 5).

The second member 122a2 and the hook engaging portions 121a2 'and 121a2 "may be formed integrally with each other, and the hook members 121a2', 121a2" The inner cover 112f of the cleaning module housing 112 shown in Fig. 5 is provided with a hook engagement portion (a second engagement portion) 121a2 'and 121a2', which project from the second member 122a2 toward the inner cover 112f. Hook insertion hole 112f2, 112f3 are formed at positions corresponding to the first and second coupling portions 121a2 ', 121a2 ".

When the cleaning module 120 passes through the cleaning module insertion hole 112g and is mounted on the module mounting portion 110a, the hook connecting portions 121a2 'and 121a2' 'pass through the hook connecting portion inserting holes 112f2 and 112f3, The first member 122a1 and the second member 122a2 are movably coupled to each other and in the course of coupling the second side cover 121a to the cleaning module housing 112, The hook engagement portions 121a2 'and 121a2' and the second member 122a2 are relatively moved with respect to the first member 122a1 and hooked to the inner cover 112f while being restored to their original positions. An elastic member (not shown) may be coupled to the second member 122a2 for movement and restoration of the second member 122a2.

The coupling of the hook engaging portions 121a2 'and 121a2' can be released by an operation applied to the hook operating portion 121b. The hook operating portion 121b is installed to be exposed on the outer surface of the third member 122a3, When the user operates the hook operating portion 121b to linearly move the hook operating portion 121b, the second member 122a2 and the hook engaging portion are moved in a linear manner by the operation of the first operating portion 121b, The hook engaging portions 121a2 'and 121a2' are pulled out of the hook engaging portions 121a1 'and 121a2' by pulling the holder 121 in this state, And is discharged through the insertion holes 112f2 and 112f3. A tool is not required to operate the hook operating portion 121b.

Fig. 8 is a concept showing the cleaning member 122. Fig.

Both ends of the cleaning member 122 are formed so as to be supported by the holder 121 and / or the rotation driving unit 130. In FIG. 7, the swinging rod 122a and the agitator 122b are shown as an example of the cleaning member 122. One end of the rotation bar 122a is provided with a protrusion 122c which can be inserted into the receiving groove 131 of the rotation driving part 130. [ The projecting portion 122c is formed to fit into the receiving groove 131. [ The coupling means that the protruding portion 122c and the receiving groove 131 have a shape corresponding to each other and can receive a rotational force. For example, when the projecting portion 122c has a hexagonal section as shown in Fig. 7, the receiving groove 131 also has a shape corresponding thereto.

The receiving groove 131 may be formed by protruding a plurality of plates 132 from the rotation driving part 130. Referring to FIG. 8, it can be seen that the six plates 132 protrude from the rotation driving part 130. Accordingly, the receiving groove 131 can receive the protrusion 122c having a hexagonal cross section.

The protrusion 122c may be formed with a protrusion 122d and each plate 132 may be formed with a hole 133 corresponding to the protrusion 122d. The protrusion 122d is engaged with the hole 133 to prevent the detachment of the cleaning member 122 as the protrusion 122c is inserted into the receiving groove 131. [

A bearing (not shown) may be coupled to the opposite side of the protrusion 122c. When the bearing is supported by the support portion 121c of the holder 121, it is possible to achieve a more smooth rotation by reducing the frictional force.

The above-described vacuum cleaner is not limited to the configuration and the method of the above-described embodiments, but all or a part of the embodiments may be selectively combined so that various modifications may be made to the embodiments.
