Description

Dust collector station

Technical Field

The present invention relates to a dust collector station combined with a dust collector to collect dust inside a dust bucket of the dust collector, and more particularly, to a dust collector station having a dust bucket in the form of a container (bin) as a member to collect and store dust instead of a dust bag (bag) that requires periodic replacement by a user.

Background

In general, a vacuum cleaner is a home appliance that sucks small garbage or dust in a manner of sucking air by using electricity and fills it into a dust tub in a product, and is generally called a vacuum cleaner.

Such a vacuum cleaner may be classified into a manual vacuum cleaner in which a user directly moves the vacuum cleaner and performs cleaning, and an automatic vacuum cleaner in which the user travels by himself and performs cleaning. The manual vacuum cleaners can be classified into a canister-type vacuum cleaner, an upright-type vacuum cleaner, a hand-held vacuum cleaner, a stick-type vacuum cleaner, etc., according to the type of the vacuum cleaner.

In recent years, a dust container and a cleaner body are integrated, and a hand cleaner and a stick cleaner which are improved in use convenience are increasingly used.

In the canister type cleaner, a brush may be mounted to a suction port for use by connecting a main body and the suction port using a rubber hose (hose) or a pipe (pipe).

The hand-held cleaner is a cleaner that maximizes portability, but may be limited in cleaning area due to its short length, although it is lightweight. Thus, it is used for cleaning local places such as desks, sofas or in automobiles.

The stick-type cleaner can be used standing, so that cleaning can be performed without bending down. Thus, the cleaning device can be moved in a wide area and cleaned. Compared with a handheld dust collector for cleaning a narrow space, the stick dust collector can clean a wider space and can clean a high place which cannot be reached by an adversary. In recent years, stick cleaners have been provided in a module form to actively change the type of the cleaner for various objects and use the same.

In addition, recently, a floor sweeping robot that performs cleaning by itself without an operation of a user is widely used. The robot automatically cleans the area to be cleaned by sucking foreign matters such as dust from the ground while the area to be cleaned is traveling by itself.

However, the capacity of a dust bucket for storing collected dust in the conventional stick-type dust collector and sweeping robot is small, so that there is a problem in that a user needs to empty the dust bucket every time.

In contrast, a cleaning device comprising a vacuum cleaner and a docking station is disclosed in Korean laid-open patent publication No. 10-2020-0074201.

In the above-mentioned prior patent documents, there is disclosed a vacuum cleaner including a dust collection tub having a function of collecting foreign matters, and a cleaning device including a docking station connected to the dust collection tub to remove the foreign matters collected in the dust collection tub, the docking station being configured to include a suction device for sucking the foreign matters in the dust collection tub.

The above-mentioned conventional patent document is configured to include a trap portion for trapping foreign matter inside the docking station.

However, in one embodiment of the above-described prior art patent document, the trap portion is constituted by a dust bag, and there is an inconvenience that periodic replacement is required. In addition, dust bags may cause dust scattering problems during separation from the docking station for replacement due to the nature of their material.

On the other hand, the above-mentioned prior patent document discloses an embodiment in which the collecting section includes an additional dust collecting tub. The additional dust collection tub is configured to include a duplex cyclone and to allow air flowing into the additional dust collection tub to pass through the duplex cyclone, so that foreign matters discharged from the dust collection tub of the cleaner can be trapped in the additional dust collection tub.

However, in another embodiment of the above-mentioned prior art patent document, the multiple cyclone part is configured to be accommodated in the inside of the additional dust collection tub, so that there is a problem in that the dust accommodation capacity of the dust collection tub is reduced by an amount corresponding to the volume of the multiple cyclone part, and if the multiple cyclone part is accommodated in the inside of the additional dust collection tub, the structure of the inside of the dust collection tub becomes complicated, and thus there is a possibility that there is a difficulty in managing the cleaning of the additional dust collection tub, etc., from the standpoint of a user.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The invention is capable of various modifications and embodiments, and therefore specific embodiments are shown in the drawings and will be described in detail herein. It is not intended to limit the invention to the particular embodiments but is to be construed to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless the context clearly indicates otherwise, singular expressions may include plural expressions.

Unless otherwise defined, all terms used herein, including technical or scientific terms, may have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms as defined in commonly used dictionaries may be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Fig. 1 is a side view schematically illustrating a cleaner system including a cleaner station according to an embodiment of the present invention, and fig. 2 is a bottom view of a cleaner combined with the cleaner station of fig. 1.

Referring to fig. 1 and 2, a cleaner system 1 of an embodiment of the present invention may include a cleaner station 10 and a cleaner 20. On the other hand, in the present embodiment, some of the components may be omitted, and additional components are not excluded.

The cleaner station 10 is a device configured to perform an operation of sucking and removing dust inside the dust tub 21 of the cleaner 20, and may be combined with the cleaner 20 to perform such a dust sucking operation. At this time, the cleaner 20 coupled to the cleaner station 10 may be a sweeping robot that autonomously travels and performs a sweeping operation.

The cleaner 20 can automatically clean an area to be cleaned by sucking foreign matters such as dust from the floor while the area to be cleaned is traveling by itself. The cleaner 20 may include a distance sensor for detecting a distance from an obstacle such as furniture or office supplies or a wall disposed in the cleaning area, and left and right wheels for movement. The cleaner 20 may be combined with the cleaner station 10. The dust sucked into the inside of the dust tub 21 of the cleaner 20 may be collected into the inside of the cleaner station 10 through a suction hole 123 described later.

The cleaner 20 may include a dust discharge hole 22. At this time, the dust discharge hole 22 may be disposed at the bottom surface of the dust tub 21 of the dust collector 20, and thus the dust tub 21 of the dust collector 20 and a suction flow path 130 described later may communicate. As an example, the dust discharge hole 22 may be in the shape of a quadrangular hole. However, in the embodiment of the present invention, the shape of the dust discharge hole 22 is not limited.

The cleaner 20 may include a discharge cover 23. At this time, the discharge cover 23 may be formed in a shape corresponding to the dust discharge hole 22, and may be provided to close the dust discharge hole 22. For this, the discharge cover 23 may be disposed at the dust discharge hole 22. In addition, one side of the discharge cover 23 may be fixed to the dust discharge hole 22 to form a fixed end, and the other side may form a free end. With such a configuration, when suction force is generated to the dust bucket 21 of the dust collector 20, the fixed end may be in a fixed state, and the free end may be moved to a lower side (toward the suction hole 123 of the coupling part 120), so that the dust discharge hole 22 may be opened. If the suction force toward the dust tub 21 of the dust collector 20 is lost, the free end of the discharge cover 23 can be moved upward, so that the dust discharge hole 22 can be re-blocked. As described above, the discharge cap 23 may communicate or close the dust bucket 21 and the suction pipe 126 of the cleaner 20 according to the moving direction of the free end.

The cleaner 20 may include a corresponding terminal 24 for charging of the battery when combined with the cleaner station 10. The counter terminal 24 may be disposed at a position where it can be connected to the charging terminals 126a and 126b of the cleaner station 10 in a state where the cleaner 20 is coupled. As an example, a pair of the counter terminals 24 may be disposed on the bottom surface of the cleaner 20. When the corresponding terminal 24 and the charging terminals 126a, 126b are electrically connected, power can be supplied from the cleaner station 10 to the cleaner 20 to charge the cleaner 20.

The cleaner station 10 may include a station body 100 and a dust separation module 200.

Before describing the specific structure of the cleaner station 10, the directions mentioned throughout the specification are first defined, and when the direction in which the cleaner 20 moves for coupling with the cleaner station 10 is defined as the front-rear direction, the side on which the cleaner 20 is coupled with the cleaner station 10 may be defined as the front. The opposite side of the front is the rear. In addition, a direction parallel to the long axis A1 of the station main body 100 may be defined as an up-down direction.

The station main body 100 is coupled to the dust collector 20 and sucks dust in the dust tub 21 of the dust collector 20, and can have a long axis A1 extending in the vertical direction.

The station body 100 may include a housing 110 formed with an inner space surrounded by a plurality of outer walls. The space may accommodate various components to protect them from external impact. For example, the components may be a dust collecting motor 140 that generates suction force to the inside of the dust tub 21 of the cleaner 20, a power module provided for charging the cleaner 20, a control circuit that controls the overall operation of the cleaner station 10, and the like.

The housing 110 may form the outer shape of the station body 100 through a plurality of the outer walls. As an example, the case 110 may have an outer shape similar to a quadrangular prism. More specifically, the housing 110 has a shape similar to a quadrangular prism as a whole, and may have a shape in which a portion coupled to the cleaner 20 is bent rearward. However, the outer shape of the housing 110 may be variously changed within a functional range that can be coupled to the cleaner 20, that can form a space inside the cleaner station 10, and that can accommodate and protect the above-described components.

On the other hand, the plurality of outer walls may include a front wall 110a disposed at the front, a rear wall 110b disposed facing the front wall 110a and facing the rear, and side walls 110c, 110d disposed between the front wall 110a and the rear wall 110b. The front wall 110a may be provided with a coupling portion 120 to be coupled to the cleaner 20. The front wall 110a may have a shape bent rearward in correspondence with a shape coupled with the cleaner 20. The back wall 110b may have a flat-sided shape as compared to the front wall 110 a. Therefore, in the indoor space where the cleaner station 10 is installed, the back wall 110b can be disposed adjacent to the wall of the indoor space, and the space utilization efficiency of the indoor space can be improved. In addition, power lines for supplying power to the cleaner station 10 may be led out at the rear wall 110b. Side walls 110c, 110d may be provided on the left and right sides, respectively, to connect the front wall 110a and the rear wall 110b. At this time, at least one corner connecting the front surface wall 110a and the side surface walls 110c, 110d or the rear surface wall 110b and the side surface walls 110c, 110d to each other may be provided to have a prescribed radius of curvature.

A partial region of the housing 110 may be configured to be capable of opening and closing between an inner space of the housing 110 and an outside of the housing 110. For example, a case opening cover (not shown) configured to be openable and closable may be provided in a partial region of the front wall 110 a. The case opening cover may be configured to be capable of opening and closing an adjacent region in which the hepa filter 150 described later is disposed.

The station body 100 may further include a coupling part 120 coupled with the cleaner 20. The cleaner 20 may climb onto the upper face of the coupling portion 120 to be coupled with the cleaner station 10. The coupling portion 120 may be disposed at one of the outer walls constituting the housing 110. For example, as in the embodiment of fig. 1, the junction 120 may be disposed on the front wall. The structure of the joint 120 will be described later with reference to fig. 3.

The station body 100 may further include a suction flow path 130.

The suction flow path 130 may be disposed in the inner space of the case 110. The suction flow path 130 is coupled to the coupling portion 120, and may be configured in a hollow pipe shape so as to be capable of sucking dust inside the dust tub 21 of the dust collector 20. That is, air containing dust discharged from the dust tub 21 of the dust collector 20 may flow inside the suction flow path 130. One side end of the suction flow path 130 is coupled to the suction hole 123 of the coupling part 120, whereby the dust bucket 21 of the cleaner 20 and the suction flow path 130 can communicate through the suction hole 123 when the cleaner 20 is coupled to the cleaner station 10.

The suction flow path 130 may include a first suction flow path 130a and a second suction flow path 130b (refer to fig. 1). The longitudinal axis of the first suction channel 130a may be arranged parallel to the long axis A1 of the station main body 100. One end of the second suction flow path 130b may be connected to the first suction flow path 130 a. In addition, the second suction flow path 130b may extend in the front-rear direction at the lower side of the coupling portion 120. The other side end of the second suction flow path 130b may be connected to the suction hole 123. Accordingly, when the cleaner 20 is coupled with the coupling part 120, the other side end of the second suction flow path 130b may communicate with the dust tub 21 of the cleaner 20.

The station body 100 may further include a dust collection motor 140.

The dust collection motor 140 may be disposed in the inner space of the housing 110. The dust collection motor 140 may provide suction to the inside of the dust tub 21 to move dust inside the dust tub 21 of the dust collector 20 through the suction flow path 130. More specifically, when the dust collection motor 140 is driven, a flow of air flow from the upper portion to the lower portion of the station main body 100 is generated, and at the same time, suction force from the dust separation module 200 described later to the dust collection motor 140 can be generated. Inside the suction flow path 130, the direction of the suction force may coincide with the direction of the dust sucked into the dust tub 21.

The station body 100 may also include a hepa filter 150.

The hepa filter 150 may be accommodated inside the housing 110 and may be disposed at a suitable position that enables the air passing through the dust collecting motor 140 to be finally filtered before being discharged to the outside of the housing 110. In a possible embodiment, the HEPA filter 150 may be disposed in the lower portion of the dust collection motor 140. Alternatively, in a possible embodiment, the HEPA filter 150 may be disposed in front of the dust collection motor 140. Alternatively, in a possible embodiment, the HEPA filter 150 may be disposed behind the dust collection motor 140.

The station body 100 may further include a control part (not shown).

The control part may be accommodated in the inner space of the housing 110, and may determine whether the cleaner 20 is coupled to the cleaner station 10 and integrally control the subsequent suction operation. At this time, the control section may include all types of devices capable of processing data such as a processor (processor). Here, the "processor" may refer to a data processing device incorporated in hardware, for example, having a circuit of a physical structure for executing a function expressed in code or instructions contained in a program. Examples of such a data processing device incorporated in hardware include a microprocessor (microprocessor), a central processing unit (central processing unit: CPU), a processor core (processor core), a multiprocessor (multiprocessor), an ASIC (application-specific integrated circuit ), an FPGA (filed programmable gate array, field programmable gate array), and the like, but the scope of the present invention is not limited thereto.

The station body 100 may further include a power module (not shown).

The power module may be accommodated in an inner space of the case 110, may convert an ac power received from the outside of the case 110 into a dc power, and may supply power to the cleaner 20 to charge a battery of the cleaner 20 when the cleaner 20 is coupled with the coupling part 120.

An exhaust unit (not shown) may be provided in the case 110 of the station main body 100. The exhaust portion may include a plurality of holes penetrating the inside and outside of the housing 110 to allow the air passing through the hepa filter 150 to be exhausted to the outside of the housing 110. In a possible embodiment, the exhaust portion may be formed in the front wall. Alternatively, in a possible embodiment, the exhaust portion may be formed at the rear wall 110b. Alternatively, in a possible embodiment, the exhaust portion may be formed at the side walls 110c, 110d.

Fig. 3 is a perspective view illustrating a coupling portion coupled with a cleaner in the cleaner station of fig. 1.

Referring to fig. 3, the coupling portion 120 may include a coupling surface 120a. The joint surface 120a is a surface formed by bending the front wall of the case 110, and may be referred to as an upper surface. The joint surface 120a may be a surface facing the bottom surface of the cleaner 20 based on the state in which the cleaner 20 is joined. The cleaner 20 may approach and climb the junction 120 from the front of the junction 120, and may be placed on the junction 120a. The shape of the coupling surface 120a may correspond to the shape of the bottom surface of the cleaner 20. For example, the bonding surface 120a may be rectangular in shape. However, in a possible embodiment, the shape of the engaging surface 120a may be different from the shape of the bottom surface of the cleaner 20.

The coupling part 120 may include a rolling part 121, and left and right wheels of the cleaner 20 pass through the rolling part 121 when the cleaner 20 climbs for coupling. When the joint 120 is viewed from the front, the rolling portions 121 may be disposed adjacent to the left and right end portions of the joint 120. The interval of the left and right rolling parts 121 may correspond to the interval of the left and right wheels of the cleaner 20 to be able to guide the movement of the left and right wheels of the cleaner 20. The rolling portion 121 may have a shape recessed downward from the joint surface 120a of the joint portion 120 so as not to separate the left and right wheels of the cleaner 20 from the moving path when moving. That is, the rolling portion 121 may be defined as a region recessed downward as compared to the coupling surface 120a adjacent to the rolling portion 121.

In addition, a wheel seating part 122 supporting left and right wheels of the cleaner 20 may be provided at the rolling part 121 so as not to move the cleaner 20 in a state of being coupled with the coupling part 120. The wheel seating part 122 may be defined as a region recessed by forming a curved surface on the rolling part 121 so as to be able to surround and support left and right wheels of the cleaner 20.

A plurality of protrusions protruding upward at predetermined intervals may be provided on the upper surface of the rolling portion 121. The protrusions form irregularities on the rolling portion 121, so that the left and right wheels can be prevented from sliding.

The coupling part 120 may include a suction hole 123, and the suction hole 123 may be provided at a position corresponding to a position of the dust tub 21 where the cleaner 20 is disposed, based on a state where the cleaner 20 is coupled with the coupling part 120. The suction flow path 130 and the dust bucket 21 may communicate through the suction hole 123. The suction hole 123 may be provided with a protrusion 124 formed to protrude upward at the coupling surface 120 a. The protrusion 124 may protrude by a height capable of compensating for a difference in positions of the discharge hole of the cleaner 20 and the coupling surface 120a when the wheels of the cleaner 20 are seated on the wheel seating part 122. By providing the suction hole 123 in the protruding portion 124, the suction force can be prevented from being reduced when the dust bucket 21 communicates with the suction flow path 130.

At this time, a caster guide 125 having the same height as the coupling surface 120a may be formed at the protrusion 124 to guide movement of the caster. In other words, in order to maintain the balance between the left and right sides of the cleaner 20, the protrusions 124 may be formed at predetermined intervals on the left and right sides, respectively, and an area of the joint surface 120a between the protrusions 124 formed by the protrusions 124 being spaced apart from each other may be defined as the caster guide 125.

The suction hole 123 may be disposed at a position corresponding to a position where the dust discharge hole 22 of the cleaner 20 is disposed when the cleaner 20 is coupled to the coupling portion 120. The suction hole 123 may be formed in a shape corresponding to the dust discharge hole 22 of the dust collector 20. As an example, the suction hole 123 may have a quadrangular hole shape.

On the other hand, the second suction flow path 130b may be accommodated in the inner space of the case 110 disposed at the lower portion of the coupling portion 120, and an end portion of the second suction flow path 130b may be connected to the suction hole 123. That is, when the discharge cover 23 of the cleaner 20 opens the dust discharge hole 22, the second suction flow path 130b and the inside of the dust bucket 21 may communicate through the suction hole 123.

The coupling part 120 may include a charging part 126 electrically connected with the cleaner 20 and supplying power to charge the cleaner 20. The charging unit 126 may include charging terminals provided on the left and right sides, respectively, with reference to a state of the coupling unit 120 viewed from the front. When the cleaner 20 is coupled to the coupling part 120, the corresponding terminal 24 of the cleaner 20 and the charging terminal are electrically connected, and the power module provided inside the housing 110 supplies power to the cleaner 20, so that the cleaner 20 can be charged. The spacing of the left and right charging terminals may be substantially the same as the spacing of the corresponding terminals 24 of the cleaner 20.

Hereinafter, various embodiments of the dust separation module 200 will be described with reference to fig. 4 to 18.

Fig. 4 is a perspective view of an embodiment of a dust separating module included in the dust collector station of fig. 1, fig. 5 is an exploded perspective view of the dust separating module of fig. 4, fig. 6 is a sectional view taken along the line X-X of fig. 4, fig. 7 is a view showing a rotating unit included in the dust separating module of fig. 4, and fig. 8 is a view of the dust collecting tub of fig. 4 from above.

Referring to fig. 4, the dust separation module 200 may include a dust collecting part 210, a dust separating part 220, and a discharge air moving part 230.

The dust collecting part 210 may include a dust collecting tub 211.

Referring to fig. 1 and 5, a dust collection tub 211 is disposed at an upper portion of the station main body 100, and may be provided to collect dust flowing together with air. The dust tub 211 may be provided in a cylindrical shape, and a longitudinal axis of the dust tub 211 may be disposed parallel to a long axis of the station body 100. The lower end of the dust tub 211 may be configured to be in contact with the upper surface of the station body 100, and the upper end of the dust tub 211 may be opened. The upper end of the dust tub 211 may be coupled with a shielding plate 222, which will be described later, and at least a portion of the open upper end of the dust tub 211 may be closed by the shielding plate 222. The dust tub 211 may be formed of a transparent material with an inside visible. Thus, the user can grasp the degree of dust collection, so that it can be easily determined whether or not the dust collected in the dust collection tub 211 needs to be emptied. The dust tub 211 may be formed of a washable material. For example, the dust tub 211 may be formed of a plastic material.

In the case where the dust storage member provided to the cleaner station 10 is a bag type (bag type) dust bag, the user needs to replace the dust bag periodically. In this case, when the capacity of the dust bag is small, frequent replacement is required, and thus, there is a problem in that convenience for the user is lowered, whereas when the capacity of the dust bag is large, it is necessary to wait for dust to fill the dust bag, and thus, the replacement period is prolonged, and thus, there is a possibility that bacteria may propagate inside the dust bag.

In contrast to this, in the case where the dust collection tub 211 of the bin type is provided as the dust storage member as in the embodiment of the present invention, the dust collection tub 211 can be semi-permanently used without replacement, and thus is not only economical but also can be cleaned, so that dust and cleaning can be emptied whenever necessary, and thus has an advantage in that the cleaner station 10 can be managed more hygienically.

The dust catching part 210 may further include a rotation unit 212 and a compression plate 213.

Referring to fig. 5, 7, and 8, the rotation unit 212 may be disposed inside the dust collection tub 211, and may be provided to rotate along an inner circumferential surface of the dust collection tub 211 centering on a longitudinal axis of the dust collection tub 211. More specifically, the rotation unit 212 may include a rotation shaft 2123, a scraper 2122, and a rotation plate 2121.

The rotation shaft 2123 is disposed along the longitudinal direction of the dust collection tub 211 and is rotatable by receiving power from the outside of the dust collection tub 211. The rotational shaft 2123 may be coaxial with the longitudinal axis of the dust tub 211. The lower end of the rotational shaft 2123 may be connected to the lower face of the dust tub 211 to be able to receive power from the outside. The rotational shaft 2123 extends adjacent to an upper end of the dust tub 211.

The rotation plate 2121 is connected between the rotation shaft 2123 and the blade 2122, and is rotatable together with the rotation shaft 2123. The rotation plate 2121 may have one end portion of the rotation plate 2121 connected to the rotation shaft 2123 and the other end portion extending radially outward of the dust collection tub 211. For example, the rotation plate 2121 may be formed in a quadrangular plate shape. The up-down direction length of the rotation plate 2121 may be formed to be similar to the length of the dust collection tub 211. When the rotation plate 2121 rotates together with the rotation shaft 2123, the wide surface of the rotation plate 2121 contacts with the wide surface of a compression plate 213 described later, so that dust collected between the rotation plate 2121 and the compression plate 213 can be compressed.

The blade 2122 may be provided to rotate together with the rotation shaft 2123 in a state of being in contact with the inner circumferential surface of the dust barrel 211. The blade 2122 may be coupled to the rotating plate 2121 on the opposite side where the rotating shaft 2123 is disposed. At this time, one side of the blade 2122 is configured to contact the inner circumferential surface of the dust barrel 211. Thereby, the scraping blade 2122 can scrape the inner circumferential surface of the dust barrel 211 when rotating together with the rotating plate 2121. The blade 2122 may be made of a flexible material. For example, the blade 2122 may be made of a rubber material.

The compression plate 213 may be configured to be fixed at one side of the inside of the dust collection tub 211 to compress the dust collected by the rotation unit 212 (refer to fig. 8). The compression plate 213 may be formed such that one end of the compression plate 213 is connected to the inner circumferential surface of the dust collection tub 211 and the other end extends inward in the radial direction of the dust collection tub 211. The compression plate 213 may be formed in substantially the same shape as the rotation plate 2121. For example, the compression plate 213 may be formed in a quadrangular plate shape.

On the other hand, referring back to fig. 7, the dust collecting part 210 may further include a dust compressing motor 214.

The dust compression motor 214 may provide power to rotate the rotational shaft 2123. The dust compression motor 214 may be disposed at an outer side of the dust barrel 211, and may be connected to the rotational shaft 2123 through a lower surface of the dust barrel 211. In a possible embodiment, the dust compression motor 214 may be directly connected with the rotational shaft 2123 by a dust compression motor 214 shaft provided to penetrate a lower face of the dust tub 211. Alternatively, in a possible embodiment, the dust compression motor 214 and the rotational shaft 2123 may be connected via a dust compression gear portion 215. At this time, the dust compression gear part 215 may include at least one gear part. A sensor capable of detecting the rotation degree of the rotation shaft 2123 may be disposed at one side of the dust compression motor 214 to control the stopping of the rotation shaft 2123. The sensor may be a micro switch.

The dust compression motor 214 may be controlled by a control section. In a possible embodiment, the direction of rotation of the dust compression motor 214 may be changed. For example, the rotation plate 2121 may rotate in a first direction to meet the compression plate 213 to compress dust. In addition, the rotation plate 2121 may rotate in a second direction opposite to the first direction to meet the compression plate 213 to compress dust.

As described above, according to the embodiment of the present invention, the dust trapped in the dust collection tub 211 can be compressed and stored by the rotation unit 212 and the compression plate 213, and thus has an effect of increasing the capacity of the dust that can be trapped as compared with the capacity of the actual dust collection tub 211, so that the dust storage efficiency inside the dust collection tub 211 is improved, and thus the convenience of the user can be improved. In addition, if the dust inside the dust collection tub 211 is compressed, there is an effect that the dust is not scattered when the dust collection tub 211 is emptied.

On the other hand, the dust compression motor 214 and the dust collection tub 211 may be configured in a separable manner. That is, the dust compression motor 214 is disposed outside the dust barrel 211, and the rotation shaft 2123, the rotation plate 2121, and the compression plate 213 may be separated from the dust compression motor 214 together with the dust barrel 211 in a state of being accommodated inside the dust barrel 211. As described above, when the dust compression motor 214 is disposed outside the dust barrel 211, there is an advantage in that the inside of the dust barrel 211 can be easily washed.

Hereinafter, the dust separating unit 220 will be described with reference to fig. 5 and 6.

The dust separating part 220 is a structure that performs a function of separating dust from air flowing through the suction flow path 130 and collecting the dust in the dust collection tub 211. The dust separating part 220 may be disposed at an upper portion of the dust tub 211. The dust separating part 220 may include an impact flow path pipe 221, a shielding plate 222, and an upper cover 223.

The impingement flow path pipe 221 is disposed at an upper outer side of the dust tub 211, and may provide a flow path through which air flowing in through the suction flow path 130 flows. In this case, the impact (impulse) is a phenomenon that, when foreign particles such as dust entering through an inlet move along a flow path of air, particles having a large size and receiving a large inertial force cannot catch up with the flow of air, which is known.

The impingement flow channel 221 may be configured such that the direction in which the dust moves inside the impingement flow channel 221 is different from the direction in which the suction force acts on the exhaust air discharged from the impingement flow channel 221. Thereby, dust contained in the air can be trapped to the dust tub 211 by the inertial force.

One end of the impingement flow channel 221 may be connected to the suction flow channel 130 to allow air to flow in through the suction flow channel 130, and the other end of the impingement flow channel 221 may be opened to allow air containing dust to be discharged.

The shielding plate 222 may be provided to be coupled to the impingement flow path pipe 221 and to close at least a portion of an upper side of the dust tub 211 and at least a portion of an upper side of a discharge air moving part 230 described later. The shielding plate 222 may be detachably coupled to an upper end portion of the dust tub 211, and functions to cover the dust tub 211. That is, the user can separate the dust collection tub 211 from the station main body 100 after separating the dust collection tub 211 from the shielding plate 222. Thereby, the dust trapped inside the dust collection tub 211 can be discharged and removed from the open upper end of the dust collection tub 211.

An upper cover 223 may be combined with an upper portion of the shielding plate 222. A dust separation space accommodating the impact flow path pipe 221 may be formed between the upper cover 223 and the shielding plate 222. More specifically, the upper cover 223 may be composed of a first cover portion 2231 and a second cover portion 2232. The first cover 2231 may be formed of a flat plate having substantially the same shape as the shielding plate 222, and the second cover 2232 may be formed so that the corner of the first cover 2231 intersects the first cover 2231 at right angles and extends downward from the corner of the first cover 2231 by a predetermined length. The lower end of the second cover 2232 may be combined with the shielding plate 222. The lower end of the upper cover 223 is opened and a space may be formed therein. That is, the upper end of the second cover 2232 may be closed by the shielding plate 222, and the lower end of the second cover 2232 may be opened.

On the other hand, relatively large dust in the air flowing in from the station main body 100 may be separated in the dust separation space. The dust separation space is a space in which air flows and a space in which dust having large particles is separated, and may be a space in which the impact flow path pipe 221 is protected from external impact.

The exhaust air moving unit 230 will be described below with reference to fig. 5 and 6.

The exhaust air moving unit 230 is configured to provide a space into which the exhaust air separated from the dust discharged from the impingement flow path pipe 221 flows and moves. The exhaust air moving part 230 may be disposed at an upper portion of the station main body 100 (refer to fig. 1). The exhaust air moving part 230 may be disposed at the rear of the dust tub 211. The discharge air moving part 230 may be disposed at a lower portion of the dust separating part 220. That is, the dust collecting part 210 and the exhaust air moving part 230 may be disposed side by side in the front-rear direction at the upper portion of the station main body 100, and the dust separating part 220 may be disposed at the upper portion of the dust collecting part 210 and the exhaust air moving part 230. In a possible embodiment, the dust collecting part 210 and the exhaust air moving part 230 may be arranged side by side in the left-right direction.

The discharge air moving part 230 may include: an exhaust air moving part housing 223 forming a space into which exhaust air discharged from the impingement flow path tube 221 flows; a pre-filter 232 disposed in the exhaust air moving unit housing 223, for further filtering dust from the exhaust air; and a suction passage connection pipe 231 disposed in the discharge air moving part case 223 and communicating with the suction passage 130.

At this time, a portion of the outer shape of the exhaust air moving part housing 223 may be formed in a shape surrounding the dust collection tub 211, and the remaining portion may be formed in a shape corresponding to the shape of the housing 110 of the station main body 100. A discharge port through which air is discharged may be provided at a lower portion of the discharge air moving part case 223, and may communicate with the dust collecting motor. The upper portion of the discharge air moving part case 223 may be opened. The discharge air moving part case 223 may be combined with the shielding plate 222. At this time, a part of the upper region of the discharge air moving part case 223 may be closed by the shielding plate 222.

The air discharged after collecting the larger dust in the dust tub 211 may be filtered once more at the pre-filter 232. The pre-filter 232 may be disposed to face a moving path along which the exhaust air flows out (refer to fig. 6). The pre-filter 232 may be disposed at a discharge port communicating with the dust collection motor 140. In addition, the shape of the pre-filter 232 may be configured to be substantially the same as the shape of the discharge port to prevent air from being discharged from the discharge port without passing through the pre-filter 232. The shape of the pre-filter 232 may be substantially the same as the shape of the exhaust air through hole 2222 described later.

The lower end of the suction flow path connection pipe 231 may communicate with the first suction flow path 130 a. The upper end of the suction channel connection pipe 231 may communicate with the impingement channel pipe 221 (see fig. 5). That is, one end of the impact flow path pipe 221 is connected to the suction flow path connection pipe 231 to communicate with the first suction flow path 130a, whereby air discharged from the dust bucket 21 of the cleaner 20 and flowing into the suction flow path 130 can be transferred to the impact flow path pipe 221.

On the other hand, the shielding plate 222 may further include: a dust through hole 2221 provided to communicate the inside of the dust collection tub 211 with the dust separation space, for passing the dust discharged from the impact flow path pipe 221; and a discharge air through hole 2222 provided to communicate the dust separation space and the discharge air moving part 230, for passing the air discharged from the impingement flow path tube 221. (refer to FIG. 6)

In addition, the impingement flow channel tube 221 may include: a first flow path tube 2211 extending in the up-down direction; and a second channel 2212 connected to the first channel 2211 and extending in a direction perpendicular to the first channel 2211 (horizontal direction) (see fig. 5). One end of the first flow path 2211 may be connected to the suction flow path connection pipe 231, and the other end of the first flow path 2211 may be connected to the second flow path 2212. One end of the second flow path 2212 may be connected to the first flow path 2211, and the other end of the second flow path 2212 may be opened at a position close to the dust through hole 2221.

Hereinafter, a process in which dust is trapped in the dust tub 211 in the present embodiment will be described with reference to fig. 6.

The air flowing into the impingement flow path pipe 221 through the suction flow path 130 and the suction flow path connection pipe 231 moves in the first direction D1 together with the dust. At this time, the suction force of the dust collection motor 140 acts in the second direction D2 toward the exhaust air through hole 2222. That is, since the first direction D1 and the second direction D2 are different from each other, at the moment when the air is discharged from the open end of the impingement flow channel pipe 221, the dust continues to move in the direction D1 by the force of inertia force, which is the force to continue to move in the original direction, and the air flows in the direction D2 by the suction force and flows into the discharged air moving part 230.

At this time, the impingement flow path pipe 221 is formed so that only the direction D1, which is the direction in which the second flow path pipe 2212 extends (or the direction in which the movement direction of the dust or the inertial force acts on the dust), and the direction D2, which is the direction in which the suction force acts on the air in the dust separation space, are different from each other, the dust can be trapped by the inertial force.

On the other hand, dust may be separated from the air moving in the direction D2 and continue to move in the direction D1, and then fall through the dust through hole 2211 to be trapped in the dust collection tub 211 after hitting the upper cover 223. The air moving in the direction D2 and flowing into the exhaust air moving part 230 may be filtered once again by the pre-filter 232 and then discharged to the outside of the housing 110.

On the other hand, the dust separating part 220 may further include a collision part 224.

Referring to fig. 6, the collision part 224 may be disposed along at least a portion of the outer boundary of the dust through hole 2221 inside the dust separation space. More specifically, the collision portion 224 may be formed to extend up and down in the dust separation space, and may be disposed in a region facing the open end of the impact flow path pipe 221 in the outer boundary of the dust through hole 2221. That is, at least one surface of the collision portion 224 may be disposed to face a direction of an inertial force acting on the dust discharged from the impact flow path pipe 221. The collision part 224 may include: a first collision part 2241, which is connected to an inner wall of the second cover part 2232 and takes a semicircular shape when the dust separation space is overlooked from the upper part; and a second collision part 2242 connected to the first collision part 2241 and extending toward the impulse flow path pipe 221. The second collision part 2242 may be disposed to extend parallel to the longitudinal axis of the second flow path tube 2212 of the impingement flow path tube 221, and to form a predetermined interval with the outer peripheral surface of the second flow path tube 2212.

With such a configuration, the air discharged from the impingement flow channel pipe 221 collides with the collision portion 224, so that the flow direction can be rapidly switched along the inner wall surface of the collision portion 224. Therefore, it can be made more difficult for the dust to follow the flow of air, so that the dust collection efficiency can be further improved.

According to the embodiment of the invention, since the dust with larger particles is trapped by utilizing the inertia force, a screen made of metal is not required, so that the dust separation structure can be simplified, the number of components required to be cleaned is reduced, and the convenience of users is further improved.

In addition, if the dust separating part 220 is disposed outside the dust barrel 211 as in the present invention, there is an effect that a space for storing dust can be increased inside the dust barrel 211.

The dust collection tub 211 and the dust separation part 220 in the dust separation module 200 may be detachably combined with the station main body 100. The dust tub 211 may be configured to be detachable in a forward direction. The dust separating part 220 may be configured to be separable toward an upper part. Since the dust collection tub 211 can be separated and the dust separation part 220 is disposed at the outside of the dust collection tub 211d so that there is no structure that the inside of the dust collection tub 211 cannot be washed with water, maintenance convenience of the cleaner station 10 can be improved.

Hereinafter, another embodiment of the dust separating module will be described.

Fig. 10 is a perspective view showing another embodiment of a dust separating module included in the dust collector station of fig. 1, fig. 11 is an exploded perspective view of the dust separating module of fig. 10, fig. 12 is a view of the impingement flow path tube of fig. 10 from above, fig. 13 is a sectional view taken along A-A of fig. 12, fig. 14 is a view of the dust separating module from above after removing a cyclone cover in the embodiment of fig. 10, and fig. 15 is a sectional view taken along B-B of fig. 14.

Referring to fig. 10 to 15, another embodiment of the dust separation module 300 may include a dust collecting part 210, a dust separating part 320, a cyclone part 330, and a discharge air moving part 340. At this time, the dust collecting part 210 has the same structure as the embodiment 200 of the dust separating module of fig. 4, and thus a repetitive description is omitted.

In the present embodiment, as in the previous embodiment, the dust can be trapped in the dust collection tub 211 by the inertial force acting on the dust through the impact flow path pipe 321, and after the larger dust is trapped in the dust collection tub 211, the minute dust can be filtered again in the cyclone part 330.

The dust separating part 320 may include an impact flow path pipe 321, a shielding plate 323, and an upper cover 324.

The impingement flow path tube 321 may include a first flow path tube 3211 and a second flow path tube 3212. The first flow path pipe 3211 may communicate with the suction flow path 130, and may suck air from the dust tub 21 of the cleaner 20. One end of the second flow path tube 3212 may be connected to the first flow path tube 3211, and the other end may be in communication with the dust tub 211.

The impingement flow channel 321 may be provided with a baffle (Louver) 322 to discharge air in a direction forming a predetermined angle with the direction in which the air flows inside the impingement flow channel 321. More specifically, the baffle 322 may be provided in plural at a predetermined interval in the second flow channel tube 3212 of the impingement flow channel tube 321. The baffle 322 is a thin plate-shaped structure provided in the opening of the second channel pipe 3212, and discharges air in a direction inclined by a predetermined angle with respect to the direction in which the air flows in the second channel pipe 3212. The baffle 322 may be disposed such that its wide surface is inclined with respect to the longitudinal axis of the second flow channel tube 3212. As a possible example, the baffle 322 may be arranged to direct air in an upward oblique direction. That is, the baffle 322 may be provided to open in an upper direction of the second flow path tube 3212.

In other words, the baffle 322 may be provided such that the direction D3 in which the baffle 322 guides the air and the direction D4 in which the air flows inside the impingement flow path duct 321 are different from each other (refer to fig. 13). That is, the dust continues to move in the direction in which the air flows inside the impact flow path pipe 321 by the inertial force, and the air from which the dust is separated is discharged from the opening of the impact flow path pipe 321 under the guide of the baffle 322.

The shielding plate 323 may be coupled to the impact flow path pipe 321 to close at least a portion of the upper portion of the dust tub 211 and at least a portion of the upper portion of the exhaust air moving part 340 (see fig. 11), which will be described later.

The upper cover 324 may be combined with an upper portion of the shielding plate 323. A dust separation space accommodating the impact flow path pipe 321 may be formed between the upper cover 324 and the shielding plate 323. More specifically, the upper cover 324 may be configured by a first cover portion 3241 and a second cover portion 3242, the first cover portion 3241 may be formed to have substantially the same shape as the shielding plate 323, and the second cover portion 3242 may be configured to contact the first cover portion 3241 at right angles to the corner of the first cover portion 3241, and may be formed by the first cover portion 3241 extending downward by a predetermined length. The lower end of the second cover portion 3242 may be coupled to a shielding plate 323. The lower end of the second cover portion 3242 may be coupled to a shielding plate 323. The lower end of the upper cover 324 is open and a space may be formed therein. That is, the upper end of the second cover portion 3242 may be closed by the first cover portion 3241, and the lower end of the second cover portion 3242 may be opened.

On the other hand, relatively large dust in the air flowing in from the station main body 100 may be separated in the dust separation space. The dust separation space is a space in which air flows and a space in which dust having large particles is separated, and may be a space in which the impact flow path pipe 321 is protected from external impact.

The cyclone part 330 may further filter dust from the discharged air separated from the dust discharged from the impact flow path pipe 321. The cyclone suction part 331 of the cyclone part 330 and the first cyclone tube 332 may be formed at the upper cover 324. The second cyclone tube 333 and the cyclone guide 334 of the cyclone part 330 may be formed at the shielding plate 323.

The cyclone suction part 331 may communicate with a dust collecting motor connection pipe 342, which will be described later, and may communicate with the first cyclone tube 332. Accordingly, the suction force of the dust collection motor 140 acts on the first cyclone tube 332 through the cyclone suction portion 331. The diameter of the first cyclone tube 332 may be smaller than the diameter of the second cyclone tube 333. Accordingly, the first cyclone tube 332 is inserted and disposed inside the second cyclone tube 333 based on the state where the upper cover 324 and the shielding plate 323 are coupled. The suction force acting on the first cyclone tube 332 causes air to flow into the second cyclone tube 333 through the cyclone guide portion 334 formed in a spiral structure, and as a result, a cyclone flow is generated inside the second cyclone tube 333.

On the other hand, the exhaust air discharged from the impingement flow path duct 321 may flow into the second cyclone duct 333 through the cyclone guide 334. The exhaust air is air from which dust having large particles is separated by striking the flow path pipe 321, and if the exhaust air flows into the second cyclone pipe 333, minute dust can be separated by cyclone flow.

The exhaust air moving part 340 may be disposed at an upper portion of the station main body 100. The exhaust air moving part 340 may be disposed at the rear of the dust tub 211. The discharge air moving part 340 may be disposed at a lower portion of the dust separating part 320. That is, the dust collecting part 210 and the exhaust air moving part 340 may be disposed side by side in the front-rear direction at the upper portion of the station main body 100, and the dust separating part 320 may be disposed at the upper portion of the dust collecting part 210 and the exhaust air moving part 340. In a possible embodiment, the dust collecting part 210 and the exhaust air moving part 340 may be arranged side by side in the left-right direction.

The exhaust air moving part 340 may include an exhaust air moving part housing 343, a suction flow path connecting pipe 341, and a dust collecting motor connecting pipe 342.

The discharge air moving part housing 343 may form a space in which minute dust filtered in the cyclone part 330 is stored. At this time, a portion of the outer shape of the exhaust air moving part housing 343 may be formed in a shape surrounding the dust collection tub 211, and the remaining portion may be formed in a shape corresponding to the shape of the station main body 100. A discharge port through which air is discharged may be disposed at a lower portion of the discharge air moving part housing 343, and an upper portion of the discharge air moving part housing 343 may be opened. The discharge air moving part housing 343 may be combined with the shielding plate 323, and at this time, a part of an upper region of the discharge air moving part housing 343 may be closed by the shielding plate 323.

The suction flow path connection pipe 341 may be disposed in the discharge air moving part housing 343 and communicate with the suction flow path 130. More specifically, the suction flow path connection pipe 341 may be formed as a hollow cylindrical pipe and may be disposed inside the discharge air moving part housing 343. The lower end of the suction flow path connection pipe 341 may communicate with the first suction flow path 130 a. The upper end of the suction flow path connection pipe 341 may communicate with the impact flow path pipe 321. That is, one end portion of the impact flow path pipe 321 (one end portion of the first flow path pipe 3211) is connected to the suction flow path connecting pipe 341 to communicate with the first suction flow path 130a, whereby air discharged from the dust bucket 21 of the cleaner 20 and flowing into the suction flow path 130 can be transferred to the impact flow path pipe 321.

The dust collecting motor connection pipe 342 may be disposed to be disposed inside the discharge air moving part housing 343 and communicate with the dust collecting motor 140 to flow the air discharged from the cyclone part 330. More specifically, the dust collecting motor connection pipe 342 may be formed as a hollow cylindrical pipe and may be disposed inside the exhaust air moving part housing 343. The lower end of the dust collecting motor connection pipe 342 may communicate with the dust collecting motor 140. The upper end of the dust collecting motor connection pipe 342 may communicate with the cyclone suction part 331. Thus, when the dust collecting motor 140 is driven, suction force acts on the cyclone suction part 331 through the dust collecting motor connection pipe 342.

On the other hand, the shielding plate 323 may include an exhaust air through hole 3232 through which air exhausted from the cyclone part 330 passes.

The discharge air through hole 3232 may communicate with the cyclone suction portion 331 and the dust collecting motor connection pipe 342. The air discharged from the impact flow path pipe 321 may flow into the second cyclone pipe 333, and may pass through the first cyclone pipe 332 and through the discharge air through hole 3232 via the cyclone suction part 331 after cyclone flow.

On the other hand, the second cyclone tube 333 may be accommodated inside the discharge air moving part housing 343. The second cyclone tube 333 may be disposed such that its longitudinal axis is parallel to the longitudinal axis of the dust tub 211, and may be disposed to penetrate the shielding plate 323. More specifically, a part of the second cyclone tube 333 at the upper side in the longitudinal direction and the cyclone guide 334 may be disposed in the dust separation space. A part of the second cyclone tube 333 on the lower side in the longitudinal direction may be disposed inside the exhaust air moving part housing 343 with reference to a state in which the shielding plate 323 is coupled to the exhaust air moving part housing 343.

The dust separation module 300 may further include a cyclone cover 350. The cyclone cover 350 may be disposed at the first cover portion 3241. More specifically, the cyclone cover 350 may be provided to be combined with an upper face of the first cover portion 3241 and cover the cyclone suction portion 331 and the first cyclone tube 332 (refer to fig. 11).

Hereinafter, the flow of air in the present embodiment will be described with reference to fig. 1 and 12 to 15.

When suction force generated when the dust collecting motor 140 is driven acts on the dust collecting motor connection pipe 342, air discharged from the dust tub 21 of the dust collector 20 can flow to a path passing through the suction flow path 130, the suction flow path connection pipe 341, and the impact flow path pipe 321. In this process, the dust having larger particles may be separated from the air and trapped in the dust collection tub 211 (refer to fig. 1 and 13).

After that, the discharged air discharged from the impingement flow path duct 321 along the inclined surface of the baffle 322 may flow into the cyclone part 330 and cyclone-flow. In this process, minute dust can be separated from the exhaust air and trapped in the exhaust air moving part housing 343 (refer to fig. 12 and 15).

The discharged air from which the fine dust is separated flows in the order of the first cyclone tube 332, the cyclone suction portion 331, and the dust collecting motor connection tube 342, and is finally filtered by the dust collecting motor 140 in the hepa filter 150 and then discharged to the outside of the housing 110 (see fig. 1, 11, and 14).

Hereinafter, a further embodiment of the dust separating module will be described.

Fig. 16 is a view showing still another embodiment of the dust separating module included in the cleaner station of fig. 1, and is a view of the impingement flow path tube from above, and fig. 17 is a sectional view taken along line C-C of fig. 16.

Another embodiment 300 of the dust separating module shown in fig. 10 to 15 and another embodiment 400 of the dust separating module shown in fig. 16 and 17 are identical to each other except for the configuration of the position where the baffle 422 is provided, and the description thereof is omitted for redundancy.

Referring to fig. 16 and 17, in the present embodiment, the baffle 422 may guide air in a sideways inclined direction. That is, the baffle 422 may be provided to open in the side direction of the impingement flow path tube 421. In other words, the baffle 422 may be disposed such that the directions D6, D7 in which the baffle 422 guides the air and the direction D5 in which the air flows inside the impingement flow path tube 421 are different from each other (refer to fig. 16). The air containing dust flows into the first flow path pipe 4211 and flows through the second flow path pipe 4212. The dust continues to move in the direction in which the air flows inside the second flow path pipe 4212 by the inertial force, and is trapped in the dust collection tub 211 through the dust through hole 3231 coupled to the end of the second flow path pipe 4212 (refer to fig. 17).

At this time, the air from which the dust is separated passes through the opening formed in the impingement flow path tube 421 and is discharged under the guide of the baffle 422. The air discharged from the impingement flow path tube 421 flows into the cyclone 330, and minute dust is separated by the cyclone flow (see fig. 12 and 15).

As described above, according to the present invention, a member of a cleaner station including a container type (bin type) instead of a bag type (bag type) is used as a foreign matter storage member, which is not required to be replaced periodically, so that not only is economical but also convenience for a user can be improved.

The present invention has been described in detail by way of specific embodiments thereof, but it is to be construed that the present invention is not limited thereto and that the present invention may be modified or improved by those skilled in the art to which the present invention pertains.

Simple variants or modifications of the invention fall within the scope of the invention, the specific protection scope of which will become clear from the scope of the appended claims.
