Description

Technical Field

[0001] The present invention relates to a vacuum cleaner station, and more particularly to a vacuum cleaner station that collects dust inside a vacuum cleaner and has a bagless type dust collection unit.

Background Art

[0002] Generally, a vacuum cleaner refers to an electric device that sucks in small garbage and dust by sucking in air using electricity and fills a dust container provided in the product, and is generally called a vacuum cleaner.

[0003] Such vacuum cleaners are classified into manual vacuum cleaners in which the user directly moves the vacuum cleaner while performing cleaning work and automatic vacuum cleaners that perform cleaning work while autonomously traveling. Manual vacuum cleaners are classified into canister-type vacuum cleaners, upright vacuum cleaners, handy-type vacuum cleaners, stick-type vacuum cleaners, and robot vacuum cleaners according to the shape of the vacuum cleaner.

[0004] As household vacuum cleaners, canister-type vacuum cleaners have been widely used in the past. Recently, handy-type vacuum cleaners and stick vacuum cleaners that integrate the dust container and the vacuum cleaner body to enhance convenience in use are increasingly used.

[0005] In a canister-type vacuum cleaner, the main body and the suction port are connected by a rubber hose or a pipe, and in some cases, a brush can be inserted into the suction port for use.

[0006] A handy-type vacuum cleaner (Hand Vacuum Cleaner) maximizes portability. Although it is lightweight, its length is short, so the cleaning range may be limited. Therefore, it is used for cleaning local areas such as on a desk, sofa, or inside a car.

[0007] Stick vacuums can be used while standing, allowing users to clean without bending over. Therefore, they are advantageous for cleaning large areas while moving around. While handheld vacuums are for cleaning small spaces, stick vacuums can clean larger spaces and reach high places that are otherwise difficult to access. Recently, stick vacuums are also offered as modular units, allowing users to proactively change the vacuum type for different purposes.

[0008] Recently, vacuum cleaners have tended to be made smaller in order to maximize portability. Consequently, vacuum cleaners produced recently have small dust container capacities, which has resulted in the inconvenience of users having to empty the dust container frequently.

[0009] To solve the above inconveniences, a vacuum cleaner station was developed. A vacuum cleaner station is a device that holds a vacuum cleaner after it has finished cleaning and sucks up the dust collected by the vacuum cleaner. Generally, a vacuum cleaner station has a dust collection unit that is much larger than the dust container of the vacuum cleaner. In other words, the dust collected by the vacuum cleaner is continuously collected in the dust collection unit of the vacuum cleaner station, and the user only needs to empty the dust collection unit of the vacuum cleaner station. This has the advantage of significantly reducing the number of times the user needs to remove dust compared to emptying the vacuum cleaner's dust container every time.

[0010] On the other hand, there are two main types of dust collection units: bag type and bagless type. The bag type is equipped with a separate bag in the dust collection unit, which collects dust, and only the bag is separated from the vacuum cleaner station and disposed of. In contrast, the bagless type does not have a separate bag in the dust collection unit, and the dust is collected by the dust collection unit itself, which is then separated from the vacuum cleaner station for removal. In this case, the bag is a single-use consumable item and is generally made of vinyl material, so there are cost issues as a bag must be purchased each time, and environmental problems as it causes environmental pollution. Therefore, in order to solve the above drawbacks, bagless type dust collection units were often installed in vacuum cleaner stations.

[0011] Generally, bagless dust collection units have longer intervals for dust removal than bag-type dust collection units. Therefore, dust collected inside a bagless dust collection unit remains inside for a considerable period of time. As a result, insects may breed in the collected dust, and if food or moisture remains, unpleasant odors may occur.

[0012] Prior art describes an invention related to a discharge station. According to the prior art, when a robotic vacuum cleaner is connected to a discharge station, dust is sucked from the robotic vacuum cleaner's dust container and collected in a bag. A latex membrane is placed at the connection point between the bag's inlet and the suction pipe. When the bag is placed in the discharge station and the top cover is closed, the suction pipe is inserted into the bag, and the suction pipe penetrates the latex membrane, causing the latex membrane to deform. This maintains airtightness between the suction pipe and the bag.

[0013] According to previous literature, since the latex membrane is always located at the bag's inlet and the suction pipe is inserted through it, it appears that the latex membrane has a hollow space through which the suction pipe can pass. Therefore, when separating the bag from the discharge station, problems may arise such as fine dust scattering from the hollow space of the latex membrane, insects escaping, or unpleasant odors spreading.

[0014] In particular, bagless types have a larger capacity to store dust compared to bag types, which allows ample time for insects to breed and for decomposition to progress, making the above problems even more serious. [Overview of the Initiative] [Problems that the invention aims to solve]

[0015] The problem that the present invention aims to solve is to provide a vacuum cleaner station equipped with a bagless type dust collection unit that prevents dust collected inside the dust collection unit from scattering to the outside, insects from escaping, and unpleasant odors from spreading when the dust collection unit is separated from the vacuum cleaner station.

[0016] Another problem that the present invention aims to solve is to provide a vacuum cleaner station that prevents dust from scattering to the outside, insects from escaping, and foul odors from spreading through the gaps in the inlet pipe cover that closes the inlet pipe, as the inlet pipe cover sags due to its own weight.

[0017] Another problem that this invention aims to solve is to provide a vacuum cleaner station in which the inlet pipe cover is firmly attached to the inlet pipe, preventing any gaps from forming.

[0018] Another problem that the present invention aims to solve is to provide a vacuum cleaner station that effectively kills microorganisms and insects present inside the dust collection section.

[0019] The problems addressed by the present invention are not limited to those described above, and any other problems not mentioned can be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0020] To achieve the above objectives, a vacuum cleaner station according to an embodiment of the present invention includes a suction channel whose inlet end communicates with the dust container of a vacuum cleaner, and a dust collection unit connected to the outlet end of the suction channel for collecting dust inside the dust container of the vacuum cleaner. The dust collection unit includes a dust collection body having a dust inlet connected to the outlet end of the suction channel, an inlet pipe extending inward from the circumferential surface of the dust inlet and forming a circle of curvature with a specific curvature at its end when viewed from one side, and an inlet pipe cover disposed at the end of the inlet pipe for opening and closing the inlet pipe.

[0021] The inlet pipe may include a first circle of curvature and a second circle of curvature that intersects the first circle of curvature.

[0022] The dust collection section includes an upper plate positioned on the upper surface, with a dust inlet formed on one side. In this case, the inlet pipe may extend downward from the upper plate.

[0023] The dust collection section may include an inlet pipe cover fixing member that fixes one side of the inlet pipe cover to the upper plate and tightly seals the inlet pipe cover to the end of the inlet pipe.

[0024] According to the first embodiment of the present invention, the dust collection section may include a rib that protrudes from the inlet pipe cover fixing member and whose end supports the inlet pipe cover. In this case, the rib can be deformed by applying pressure to the inlet pipe cover.

[0025] According to a second embodiment of the present invention, the inlet pipe cover may include a connecting portion that connects to the inlet pipe, a closing portion that opens and closes the end of the inlet pipe, and a bent portion disposed between the connecting portion and the closing portion. The inlet pipe cover fixing member may include an inlet pipe cover insertion groove into which at least a portion of the inlet pipe cover is inserted.

[0026] The dust collection part is arranged on one side of the dust inlet and may include a side wall extending into the internal space.

[0027] The dust collection part may include a suction channel sealing material that extends radially inward from the dust inlet and whose inner end is in close contact with the suction channel.

[0028] The vacuum cleaner station may further include a germicidal light emitting member arranged outside the dust collection body, and the dust collection part may include a germicidal light irradiation part that transmits the germicidal light irradiated from the germicidal light emitting member into the interior of the dust collection body.

[0029] At this time, the gasket may be coupled to the inflow pipe. Alternatively, the gasket may be coupled to the inflow pipe cover and move together with the inflow pipe cover.

[0030] Specific matters of other embodiments are included in the detailed description and drawings.

Effects of the Invention

[0031] According to the vacuum cleaner station of the present invention, one or more of the following effects can be obtained. [[ID=ly]]

[0032] First, since it includes an inflow pipe cover that is arranged at the end of the inflow pipe and opens and closes the inflow pipe, when the dust collection part is separated from the vacuum cleaner station, closing the inflow pipe can prevent dust from scattering outside, insects from escaping, and bad odors from spreading.

[0033] Second, since the end of the inflow pipe forms a curvature circle with a specific curvature, it also has the effect of firmly sealing the inflow pipe without sagging due to its own weight.

[0034] Third, since the dust collection part includes ribs that press and deform while supporting the inflow pipe cover, the inflow pipe cover is deformed and adheres more firmly to the end of the inflow pipe, and also has the effect of forming a curvature and adhering.

[0035] Fourth, the inlet pipe cover is open at the front and has side walls on both sides of the inlet pipe. As a result, the air that flows in through the inlet pipe cannot flow backward due to the inlet pipe cover, nor can it flow laterally due to the side walls, so it must flow forward. Furthermore, a germicidal light irradiation unit is positioned in front of the inlet pipe and germicidal light is irradiated, which also has the effect of effectively killing and sterilizing microorganisms and insects.

[0036] The effects of the present invention are not limited to those described above, and any other effects not mentioned will be clearly understood by those skilled in the art from the claims. [Brief explanation of the drawing]

[0038] The advantages, features, and methods for achieving them of the present invention will become apparent by referring in detail to the embodiments described below, along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be carried out in various different forms. These embodiments are provided only to complete the disclosure of the present invention and to allow a person ordinary skill in the art to fully understand the scope of the invention, and the present invention is defined solely by the claims. Throughout the specification, the same reference numerals refer to the same components.

[0039] The present invention will be described below with reference to drawings illustrating a vacuum cleaner station 100 according to embodiments of the present invention.

[0040] The vacuum cleaner system is divided into a vacuum cleaner 200 and a vacuum cleaner station 100. The vacuum cleaner is a movable component that sucks up dust present in the cleaning area while moving and collects it in a dust container located inside. The vacuum cleaner is a fixed, immovable component that sucks up dust from the vacuum cleaner after cleaning and collects it in dust collection units 140 and 240 located inside.

[0041] The connection of the vacuum cleaner 200 to the vacuum cleaner station 100 can include: the vacuum cleaner being fixed to the vacuum cleaner station 100 and mechanically coupled; the terminals of the vacuum cleaner and the terminals of the vacuum cleaner station 100 being in contact and electrically coupled; and the dust container of the vacuum cleaner and the dust collection sections 140 and 240 of the vacuum cleaner station 100 being in communication so that air can flow between them.

[0042] Vacuum cleaner 200 could refer to a vacuum cleaner that is operated manually by the user. For example, vacuum cleaner 200 could refer to a handheld vacuum cleaner or a stick vacuum cleaner.

[0043] The vacuum cleaner 200 may include a main unit 210. The main unit 210 may include a main unit housing 211, a suction unit 212, a dust separation unit 213, a suction motor 214, an air discharge cover 215, a handle 216, an extension unit 217, and an operating unit 218.

[0044] The main housing 211 can form the external appearance of the vacuum cleaner 200. The main housing 211 can provide space to house a suction motor 214 and a filter (not shown). The main housing 211 may be configured in a shape close to a cylinder.

[0045] The suction section 212 may protrude outward from the main housing 211. For example, the suction section 212 may be formed in a cylindrical shape. The suction section 212 can communicate with the extension pipe 250. The suction section 212 can provide a flow path through which air containing dust can flow.

[0046] The dust separation unit 213 can communicate with the suction unit 212. The dust separation unit 213 can separate dust that has been sucked into the unit via the suction unit 212. The dust separation unit 213 can communicate with the dust container 220.

[0047] The dust separation unit 213 may be a cyclone capable of separating dust by cyclone flow.

[0048] The suction motor 214 can generate a suction force to draw in air. The suction motor 214 may be housed within the main body housing 211. The suction motor 214 can generate a suction force by rotation. For example, the suction motor 214 may be provided in a shape close to a cylinder.

[0049] The air exhaust cover 215 may be located on the main housing 211. The air exhaust cover 215 may house a filter for filtering the air. For example, the air exhaust cover 215 may house a HEPA filter.

[0050] The handle 216 may be held by the user. The handle 216 may be positioned behind the suction motor 214. For example, the handle 216 may be formed in a shape close to a cylinder. Alternatively, the handle 216 may be formed in a bent cylindrical shape. The handle 216 may be positioned at a predetermined angle with respect to the main body housing 211, the suction motor 214, or the dust separation unit 213.

[0051] The extension 217 may extend from the handle 216 toward the main housing 211. At least a portion of the extension 217 may extend horizontally.

[0052] The control unit 218 may be located on the handle 216. The control unit 218 may also be located on an inclined surface formed in the upper region of the handle 216. The user can input operation and stop commands for the first vacuum cleaner 200 through the control unit 218.

[0053] The vacuum cleaner 200 may include a dust container 220. The dust container 220 can communicate with the dust separation unit 213. The dust container 220 can store dust separated from the dust separation unit 213.

[0054] The vacuum cleaner station 100, when connected to the vacuum cleaner 200, is a component that charges the vacuum cleaner, sucks up dust collected in the vacuum cleaner's dust container, or safely stores the vacuum cleaner after cleaning.

[0055] The vacuum cleaner station 100 includes a housing 110. The housing 110 forms the outer shape of the vacuum cleaner station 100 and forms a space inside which other components are housed. The housing 110 may be formed in a columnar shape including at least one outer wall surface. For example, the housing 110 may be formed in a shape close to a rectangular prism.

[0056] A coupling portion 120 is positioned within the housing 110. The coupling portion 120 is a component that supports the vacuum cleaner when it is connected to the vacuum cleaner station 100.

[0057] The suction passage 130 has an inlet end that communicates with the dust container (not shown) of the vacuum cleaner, and an outlet end that communicates with the inlet pipe 144 of the dust collection sections 140 and 240. The suction passage 130 is a pipe or tube that has a hollow interior to allow air containing dust to flow through it.

[0058] A dust collection motor 190 is positioned in the housing 110. The dust collection motor creates negative pressure to create airflow in the suction passage 130 or the discharge passage (not shown). The dust collection motor communicates with the suction passage 130 and the discharge passage (not shown).

[0059] A filter (not shown) is placed in the housing 110. For example, the filter may be placed between the dust collection units 140, 240 and the dust collection motor.

[0060] The dust collection units 140 and 240 are components that collect dust from inside the dust container of the vacuum cleaner. The dust collection units 140 and 240 are housed inside the housing 110 of the vacuum cleaner station 100.

[0061] The dust collection units 140 and 240 according to the present invention are of the bagless type. There are two main types of dust collection units 140 and 240: bag type and bagless type. The bag type is equipped with a separate bag for the dust collection units 140 and 240, and the dust is collected in the bag, with only the bag being separated from the vacuum cleaner station 100 and discarded. In contrast, the bagless type does not have a separate bag for the dust collection units 140 and 240, and the dust is collected by the dust collection units 140 and 240 themselves, with the dust being separated from the vacuum cleaner station 100 to remove the dust.

[0062] The dust collection units 140 and 240 according to the present invention are arranged to be detachable from the vacuum cleaner station 100. When the dust collection units 140 and 240 are separated from the vacuum cleaner station 100, the collected dust is removed and the inside is cleaned. When the dust collection units 140 and 240 are separated from the vacuum cleaner station 100, the connection between the suction channel 130 and the dust inlets 1412, 1422, and 1432 is released. Therefore, problems such as insects escaping to the outside, dust scattering, and foul odors spreading may occur through the dust inlets 1412, 1422, and 1432. Therefore, in order to solve the above-mentioned problems, the dust collection units 140 and 240 according to the present invention are equipped with inlet pipe covers 145 and 245, thereby solving problems such as insects escaping to the outside, dust scattering, and foul odors spreading through the dust inlets 1412, 1422, and 1432.

[0063] The dust collection units 140 and 240 according to the present invention may include the dust collection unit 140 according to the first embodiment and the dust collection unit 240 according to the second embodiment. Hereinafter, the dust collection unit 140 according to the first embodiment will be described first, and the dust collection unit 240 according to the second embodiment will be described focusing on the differences from the dust collection unit 240 according to the first embodiment.

[0064] The dust collection unit 140 according to the first embodiment will be described with reference to Figures 1 to 10. The dust collection unit 140 according to the first embodiment includes a dust collection body 141, an outer upper plate 142, an inner upper plate 143, and an inlet pipe 144. The dust collection body 141, the outer upper plate 142, and the inner upper plate 143 are arranged inside the dust collection unit case 147.

[0065] The dust collection unit case 147 forms the outer shape of the dust collection unit 140 and creates a space inside in which the various components of the dust collection unit 140 are housed.

[0066] The front of the dust collection unit case 147 is open, and the components of the dust collection unit 140 are inserted into the front.

[0067] The dust collection unit case includes a light-emitting member installation section 1471. The light-emitting member installation section 1471 forms a space in which a germicidal light-emitting member is provided. The light-emitting member installation section 1471 may be formed in the upper wall of the dust collection unit case 147.

[0068] The dust collection unit case 147 includes a dust inlet 1472. The dust inlet 1472 is a hole that penetrates the dust collection unit case 147 vertically. The dust inlet 1472 of the dust collection unit case 147 communicates with the dust inlet 1422 of the outer upper plate 142, the dust inlet 1432 of the inner upper plate 143, and the dust inlet 1412 of the dust collection body 141. The suction channel 130 is inserted into the dust inlet 1472 of the dust collection unit case 147.

[0069] The dust collection body 141 forms the outer shape of the dust collection section 140 and has an internal space in which dust is collected.

[0070] The dust collection body 141 is detachably mounted inside the housing 110 of the vacuum cleaner station 100. Specifically, the dust collection body 141 is detachable from the front of the housing 110 of the vacuum cleaner station 100.

[0071] Referring to Figure 5, the dust collection body 141 is formed in a shape close to a hexahedron. However, it is not limited to this and may be formed in other polyhedrons or cylindrical shapes.

[0072] A dust inlet 1412 is formed in the dust collection body 141. The dust inlet 1412 of the dust collection body 141 is formed on the upper surface.

[0073] Alternatively, the upper surface of the dust collection body 141 may be open, and an upper plate with a dust inlet 1412 formed thereon may be placed on the upper surface of the dust collection body 141.

[0074] The dust inlet 1412 of the dust collection body 141 is positioned to overlap with the dust inlet 1422 of the outer upper plate 142 and the dust inlet 1432 of the inner upper plate 143. Therefore, the dust inlet 1412 of the dust collection body 141 communicates with the dust inlet 1422 of the outer upper plate 142 and the dust inlet 1432 of the inner upper plate 143.

[0075] The following dust inlets 1412, 1422, and 1432 may include the dust inlet 1412 of the dust collection body 141, the dust inlet 1422 of the outer top plate 142, and the dust inlet 1432 of the inner top plate 143, as long as there is no contradiction.

[0076] The dust collection body 141 includes a germicidal light irradiation section 1411. The germicidal light irradiation section 1411 transmits germicidal light. The germicidal light irradiation section 1411 may be formed to protrude or recede from the dust collection body 141 in order to diffuse or focus the germicidal light.

[0077] The germicidal light irradiation section 1411 of the dust collection body 141 is positioned to overlap vertically with the light-emitting member mounting section 1471 of the dust collection case 147, the germicidal light irradiation section 1421 of the outer upper plate 142, and the germicidal light irradiation section 1431 of the inner upper plate 143.

[0078] The upper plates 142 and 143 are positioned on the upper surface of the dust collection section 140. The upper plates have dust inlets 1422 and 1432 formed on one side.

[0079] The top plate includes an external top plate 142 and an internal top plate 143.

[0080] The outer top plate 142 is positioned on the outer surface of the upper wall of the dust collection body 141. The outer top plate 142 may also be positioned perpendicular to the suction passage 130.

[0081] The outer top plate 142 includes a dust inlet 1422. The dust inlet 1422 is a hole that penetrates the outer top plate 142 vertically. The dust inlet 1422 of the outer top plate 142 communicates with the dust inlet 1432 of the inner top plate 143 and the dust inlet 1412 of the dust collection body 141. A suction channel 130 may be inserted into the dust inlet 1422 of the outer top plate 142.

[0082] The outer upper plate 142 includes a germicidal light irradiation section 1421. The germicidal light irradiation section 1421 transmits germicidal light. The germicidal light irradiation section 1421 may be formed to protrude or recede from the outer upper plate 142 in order to diffuse or focus the germicidal light.

[0083] The germicidal light irradiation section 1421 of the outer upper plate 142 is positioned to overlap vertically with the light-emitting member installation section 1471 of the dust collection case 147, the light-emitting member irradiation section 1411 of the dust collection body 141, and the germicidal light irradiation section 1431 of the inner upper plate 143.

[0084] The upper plate includes a suction channel sealing material 1423. The suction channel sealing material 1423 is a component that maintains airtightness between the suction channel 130 and the dust collection section 140. The suction channel sealing material 1423 seals the gap between the dust inlets 1422 and 1432 and the suction channel 130, preventing dust and other foreign matter from scattering into the gap.

[0085] The suction channel sealing material 1423 may be placed on the outer upper plate 142. Alternatively, the suction channel sealing material 1423 may be placed on the inner upper plate 143.

[0086] The suction channel sealing material 1423 extends radially inward from the dust inlets 1422 and 1432, with its inner end in close contact with the suction channel 130.

[0087] The inner diameter of the suction channel sealing material 1423 may be smaller than the outer diameter of the suction channel 130. Therefore, when the suction channel 130 is inserted into the dust inlets 1422 and 1432, the suction channel sealing material 1423 can deform inward to adhere more firmly to the outer surface of the suction channel 130.

[0088] The internal upper plate 143 is positioned on the inner surface of the upper wall of the dust collection body 141. The internal upper plate 143 may also be positioned perpendicular to the suction passage 130.

[0089] The internal upper plate 143 includes a dust inlet 1432. The dust inlet 1432 is a hole that penetrates the internal upper plate 143 vertically. The dust inlet 1432 of the internal upper plate 143 communicates with the dust inlet 1422 of the external upper plate 142 and the dust inlet 1412 of the dust collection body 141.

[0090] The internal upper plate 143 includes a germicidal light irradiation section 1431. The germicidal light irradiation section 1431 transmits germicidal light. The germicidal light irradiation section 1431 may be formed to protrude or recede from the internal upper plate 143 in order to diffuse or focus the germicidal light.

[0091] The germicidal light irradiation section 1431 of the internal upper plate 143 is positioned to overlap vertically with the light-emitting member installation section 1471 of the dust collection case 147, the light-emitting member irradiation section 1411 of the dust collection body 141, and the germicidal light irradiation section 1421 of the external upper plate 142.

[0092] An inlet pipe 144 is positioned on the internal upper plate 143.

[0093] The inlet pipe 144 is in communication with the suction passage 130 and is a component that guides dust flowing through the suction passage 130 into the interior of the dust collection body 141.

[0094] The inlet pipe 144 extends inward from the circumferential surface of the dust inlets 1412, 1422, and 1432, and when viewed from one side, its end forms a circle of curvature with a specific curvature. Specifically, the inlet pipe 144 extends downward from the dust inlet 1432 of the internal upper plate 143.

[0095] The inlet pipe 144 includes a first curvature circle C1 and a second curvature circle C2. The second curvature circle intersects the first curvature circle.

[0096] Referring to Figure 8, when viewed from the right side, the lower end of the inlet pipe 144 forms a curved surface. This curved surface follows the trajectory of the first circle of curvature, which is a hypothetical curve extending forward and backward. The center of the first curvature is located at the bottom of the inlet pipe 144, centered on its cross-sectional area. When the cover of the inlet pipe 144 is tightly fitted to it, the inlet pipe 144 is deformed into an upwardly convex shape such that its center is higher than its front and rear ends.

[0097] Referring to Figure 9, when viewed from the front, the lower end of the inlet pipe 144 forms a curved surface. This curved surface follows the trajectory of the second circle of curvature. The second circle of curvature is a hypothetical curve extending to the left and right. The center of the second curvature is located at the bottom of the inlet pipe 144, centered on its cross-sectional area. When the inlet pipe cover 145 is in close contact with the inlet pipe 144, the inlet pipe 144 is deformed into an upward-convex shape such that its center is higher than its left and right ends.

[0098] The first circle of curvature intersects the second circle of curvature. For example, the first circle of curvature may extend forward and backward, while the second circle of curvature may extend to the left and right. As a result, when the front end of the inlet pipe cover 145 tries to sag downward due to its own weight, the deformation caused by the second circle of curvature prevents the front end of the inlet pipe cover 145 from sagging downward. Conversely, when the left or right end of the inlet pipe cover 145 tries to sag downward due to its own weight, the deformation caused by the first circle of curvature prevents the front end of the inlet pipe cover 145 from sagging downward.

[0099] A first projection 1443 is formed on the inlet pipe 144. The first projection 1443 is formed to protrude further downward at the lower end of the inlet pipe 144. The first projection 1443 is inserted into a groove formed on the upper surface of the second projection 1453 of the inlet pipe cover 145.

[0100] The inlet pipe cover 145 is a component that opens and closes the inlet pipe 144.

[0101] The inlet pipe cover 145 is positioned at the end of the inlet pipe 144.

[0102] Referring to Figure 8, when viewed from the right side, the inlet pipe cover 145 conforms tightly to the inlet pipe 144 and deforms to the first curvature.

[0103] Referring to Figure 9, when viewed from the front, the inlet pipe cover 145 conforms tightly to the inlet pipe 144 and deforms to the second curvature.

[0104] Referring to Figure 10, the inlet pipe cover 145 can be manufactured in a flat shape, but it deforms to have a first curvature and a second curvature when it is in close contact with the end of the inlet pipe 144. The first curvature and the second curvature are different from each other.

[0105] The inlet pipe cover 145 according to the first embodiment is divided into a connecting portion 1451 and a closing portion 1452. The connecting portion 1451 and the closing portion 1452 are formed integrally.

[0106] The closing portion 1452 is in close contact with the end of the inlet pipe 144 and opens and closes the inlet pipe 144. The closing portion 1452 is formed in a shape corresponding to the cross-sectional area of ​​the inlet pipe 144. For example, the closing portion 1452 may be formed from a circular plate.

[0107] The connecting portion 1451 is positioned on one side of the closing portion 1452 and fixes the closing portion 1452 to the internal upper plate 143. Specifically, the connecting portion 1451 may be formed at the rear end of the closing portion 1452. The connecting portion 1451 may be fitted to the inlet pipe 144 and the inlet pipe cover fixing member 146 and joined by heat fusion.

[0108] The inlet pipe cover 145 may include a second projection 1453. The second projection 1453 is formed to protrude further downward from the connection portion 1451 of the inlet pipe cover 145. The lower end of the second projection 1453 is inserted into a groove formed on the upper surface of the third projection 1463 of the inlet pipe cover fixing member 146. A groove may be formed at the upper end of the second projection 1453 into which the first projection 1443 is inserted. The lower end of the second projection 1453 is inserted into and fixed in a groove formed on the upper part of the third projection 1463, and the groove formed at the upper end of the second projection 1453 is fixed by the insertion of the lower end of the first projection 1443.

[0109] The inlet pipe cover 145 may project further radially outward from the inlet pipe 144. Referring to Figure 8, the inlet pipe cover 145 projects further forward from the inlet pipe 144. Referring to Figure 9, the inlet pipe cover 145 projects further to the left or right of the inlet pipe 144. Since the diameter of the inlet pipe cover 145 is larger than the diameter of the outer surface of the inlet pipe 144, the inlet pipe cover 145 can cover the entire lower surface of the inlet pipe 144.

[0110] The inlet pipe cover 145 may be formed from a flexible rubber material, and the inlet pipe 144 may be formed from a rigid resin material. In this case, since the inlet pipe cover 145 protrudes further radially outward from the inlet pipe 144, the inlet pipe cover 145 retracts inward, increasing the contact area with the inlet pipe 144 and providing the advantage of further improving the sealing effect.

[0111] Furthermore, when the dust collection motor 190 is operating, the effective area on the inlet pipe cover 145 where the negative pressure generated by the dust collection motor 190 is applied increases, which has the advantage of making it easier to open the inlet pipe cover 145.

[0112] The inlet pipe cover fixing member 146 is a component that connects the inlet pipe cover 145 to the dust collection body 141 or the upper plate. The inlet pipe cover fixing member 146 fixes one side of the inlet pipe cover 145 to the upper plate and brings the inlet pipe cover 145 into close contact with the end of the inlet pipe 144.

[0113] The connection portion 1451 of the inlet pipe cover 145 is inserted into the inlet pipe cover fixing member 146. The lower surface of the connection portion 1451 is supported by the inlet pipe cover 145, and the upper surface of the connection portion 1451 is supported by the inlet pipe 144.

[0114] The inlet pipe cover 145 may include a third projection 1463. The third projection 1463 is formed to protrude further downward from the inlet pipe cover fixing member 146. A groove is formed at the upper end of the third projection 1463 so that the second projection can be inserted.

[0115] The inlet pipe cover 145 can be fixed in the correct position by inserting the first projection 1443 into a groove formed on the upper part of the second projection 1453, and the lower end of the second projection 1453 into a groove formed on the upper part of the third projection 1463. Subsequently, the inlet pipe cover 145, the inlet pipe 144, and the inlet pipe cover fixing member 146 are firmly joined by heat fusion.

[0116] Referring to Figure 8, the dust collection section 140 includes ribs 1462. The ribs 1462 support the inlet pipe cover 145, and specifically deform the shape of the inlet pipe cover 145 to form curvature.

[0117] The rib 1462 protrudes from the inlet pipe cover fixing member 146, and its end supports the inlet pipe cover 145.

[0118] The rib 1462 presses on and deforms the inlet pipe cover 145. The lower surface of the inlet pipe cover 145 is supported by the inner surface of the inlet pipe cover fixing member 146. Since the rib 1462 is formed to protrude further upward from the inner surface of the inlet pipe cover fixing member 146, it presses upward on one side of the lower surface of the inlet pipe cover 145, causing the portion of the inlet pipe cover 145 that contacts the rib 1462 to deform upward.

[0119] The rib 1462 is positioned radially outward of the suction passage 130. The rib 1462 extends along the circumferential direction of the suction passage 130.

[0120] The rib 1462 is positioned radially inward of the inlet pipe 144.

[0121] The rib 1462 is positioned radially inward from the third end. The rib 1462, the inner surface of the inlet pipe cover fixing member 146, and the third end may be formed with a two-stage step. This minimizes the risk of tearing or damage occurring when the inlet pipe cover 145 deforms.

[0122] The dust collection section 140 includes a side wall 1461. The side wall 1461 is a component that restricts and guides the direction of airflow into the interior of the dust collection body 141. The side wall 1461 is located on one side of the dust inlet 1432 and extends into the interior space.

[0123] The side walls 1461 are positioned symmetrically on the left and right sides of the inlet pipe 144. Therefore, the side walls 1461 block the air flowing into the inlet pipe 144 from flowing to the left or right. In addition, the inlet pipe cover 145 has its connection portion 1451 positioned at the rear and its front end open, thus blocking the air flowing into the inlet pipe 144 from flowing backward. Therefore, as shown in Figure 11, the air flowing into the inlet pipe 144 flows forward and downward.

[0124] Referring to Figure 11, the air flowing into the inlet pipe 144 flows forward and downward. Since the germicidal light emitting member and germicidal light irradiation units 1421 and 1431 are positioned in front of the inlet pipe 144, germicidal light is irradiated in front of the inlet pipe 144. Therefore, microorganisms and insects contained in the air flowing into the inlet pipe 144 are sterilized or killed by the germicidal light.

[0125] The vacuum cleaner station 100 includes a germicidal light emitting member 150. The germicidal light emitting member is positioned outside the dust collection body 141. The germicidal light emitting member irradiates germicidal light into the inside of the dust collection body 141.

[0126] The germicidal light may be UV (Ultra-Violet) light. Since germicidal light is a well-known type of light with a wavelength that can be easily adopted by ordinary technicians, a detailed explanation will be omitted.

[0127] The dust collection unit 140 includes germicidal light irradiation units 1421 and 1431. The germicidal light irradiation units 1421 and 1431 transmit germicidal light emitted from a germicidal light emitting member into the interior of the dust collection body 141.

[0128] The germicidal light irradiation sections 1421 and 1431 may be formed in the dust collection body 141, the outer upper plate 142, and the inner upper plate 143.

[0129] The germicidal light irradiation sections 1421 and 1431 may be formed from a transparent or translucent material so as to transmit germicidal light.

[0130] The germicidal light irradiation sections 1421 and 1431 may be recessed inward or protrude outward in the upper plate in order to diffuse or focus the germicidal light.

[0131] The germicidal light irradiation units 1421 and 1431 may be positioned in front of the inlet pipe 144. Since the air flowing into the inlet pipe 144 flows forward and downward, the germicidal light irradiated inside through the germicidal light irradiation units 1421 and 1431 can kill microorganisms and insects contained in the incoming air.

[0132] The dust collection unit 240 according to the second embodiment will be described below with reference to Figures 11 to 17. The dust collection unit 240 according to the second embodiment will be described using the description of the dust collection unit 140 according to the first embodiment to the extent that it does not contradict the first embodiment, and descriptions of the same features will be omitted. The dust collection unit 240 according to the second embodiment will be described below, focusing on the differences from the dust collection unit 140 according to the first embodiment.

[0133] The inlet pipe cover 245 according to the second embodiment is divided into a connecting portion 2451, a closing portion 2452, and a bent portion 2453.

[0134] The connecting portion 2451 is connected to the inlet pipe 244. The connecting portion 2451 is positioned on one side of the closing portion 2452 and fixes the closing portion 2452 to the inlet pipe cover fixing member 246. Specifically, the connecting portion 2451 is inserted and fitted into the inlet pipe cover fixing member 246 and heat-sealed.

[0135] The closing portion 2452 opens and closes the end of the inlet pipe 244. The closing portion 2452 is formed in a shape corresponding to the cross-sectional area of ​​the inlet pipe 244, and is similar to the inlet pipe cover 145 in the first embodiment.

[0136] The bent portion 2453 is positioned between the connecting portion 2451 and the closing portion 2452. The inclination of the connecting portion 2451 and the closing portion 2452 may be different with respect to the bent portion. For example, with respect to the bent portion, the connecting portion 2451 has a rearward downward inclined surface, and the closing portion 2452 has a frontward downward inclined surface.

[0137] The inlet pipe cover 245 has a restorative force of its own because the connecting portion 2451 and the closing portion 2452 deform around the bent portion.

[0138] The inlet pipe cover fixing member 246 is manufactured integrally with the internal upper plate 143. Alternatively, the inlet pipe cover fixing member 246 may be manufactured separately from the internal upper plate 143 and then joined together.

[0139] The inlet pipe cover fixing member 246 includes an inlet pipe cover insertion groove 2462. At least a portion of the inlet pipe cover 245 is inserted into the inlet pipe cover insertion groove and fixed in place.

[0140] Referring to Figures 15 and 17, the inlet pipe cover insertion groove may have a rearward-downward inclined surface and extend in the left-right direction. This allows the inlet pipe cover 245 to be inserted from the front upper part toward the rearward-downward direction.

[0141] Referring to Figure 26, the inlet pipe cover 245 is formed in a flat shape, but it may be deformed when installed. Referring to Figure 26a, the inlet pipe cover 245 before installation is formed flat. In contrast, referring to Figure 26b, the inlet pipe cover 245 after installation is formed in a V-shape around the bent portion 2453. Therefore, a restoring force is applied upward to the closing portion 2452, allowing it to tightly adhere to the lower end of the inlet pipe 244.

[0142] Referring to Figure 26, the inlet pipe cover 245 is connected to the rear end of the inlet pipe 244, and the front end of the inlet pipe 244 is positioned lower than the rear end of the inlet pipe 244. When the inlet pipe cover 245 is connected to the rear end of the inlet pipe 244, there is a problem that the front end of the inlet pipe cover 245 may sag and potentially detach from the inlet pipe 244 first. However, by positioning the front end of the inlet pipe 244 lower than the rear end of the inlet pipe 244, the maximum restoring force is applied to the front end of the inlet pipe cover 245, which has the effect of making the front end of the inlet pipe cover 245 adhere more firmly to the inlet pipe 244.

[0143] Figure 17 shows the assembly method of the internal upper plate 243 and the inlet pipe cover 245. Referring to Figure 26a, the inlet pipe cover 245 is inserted into the inlet pipe cover insertion groove 2462 of the inlet pipe cover fixing member 246 located on the internal upper plate 243. Referring to Figure 26b, the internal upper plate 243 with the inlet pipe cover 245 attached is fixed in close contact with the upper surface of the dust collection body 241. At this time, the support projection 2422 pressurizes the connection portion 2451 of the inlet pipe cover, and the closing portion 2452 can apply a strong restoring force.

[0144] The support projection 2422 is a component that supports the inlet pipe cover 245. The support projection extends downward from the upper plate and, together with the inlet pipe cover fixing member 246, fits the inlet pipe cover 245.

[0145] The support projection extends downward from the internal upper plate 143.

[0146] The lower surface of the inlet pipe cover 245 is supported by being in close contact with the inner surface of the inlet pipe cover fixing member 246. The upper surface of the inlet pipe cover 245 is supported by a support projection.

[0147] The support projection is positioned radially outward of the inlet pipe 144. The support projection may also extend along the circumferential direction of the inlet pipe 144.

[0148] Referring to Figure 19, according to another embodiment of the present invention, the vacuum cleaner station includes a magnetic member 2454 and a corresponding member 2444.

[0149] The inlet pipe cover 245 includes a magnetic member 2454 that generates a magnetic field. The inlet pipe 244 includes a corresponding member 2444 that generates an attractive force in response to the magnetic field.

[0150] The magnetic element 2454 is a component that generates a magnetic field and may be a magnet.

[0151] The magnetic member 2454 may be a separate object inserted into the inlet pipe cover 245. Alternatively, the magnetic member 2454 may be formed in the shape of a thin plate and placed on the upper surface of the inlet pipe cover 245. Alternatively, the inlet pipe cover 245 itself may be formed from a magnetic material.

[0152] The magnetic member 2454 may be positioned on the outer circumference of the inlet pipe cover 245. For example, the magnetic member 2454 may be positioned at the end of the inlet pipe cover 245 furthest from the connection point. Alternatively, the magnetic member 2454 may be positioned along the outer surface of the inlet pipe cover 245.

[0153] The corresponding member 2444 is positioned at the lower end of the inlet pipe. The corresponding member 2444 faces the magnetic member 2454.

[0154] The corresponding member 2444 may be a magnet having a different polarity from the magnetic member 2454. Alternatively, the corresponding member 2444 may be made of a magnetizable metallic material such as an iron core.

[0155] Referring to Figures 19 and 20, another embodiment of the present invention, a vacuum cleaner station, includes an adhesive member 248.

[0156] The adhesive member 248 is a component that more firmly fixes the dust collection body 241 and the internal upper plate 243 and seals the gap between the dust collection body 241 and the internal upper plate 243.

[0157] The adhesive member 248 is positioned between the dust collection body 241 and the internal upper plate 243. Specifically, the upper surface of the adhesive member 248 is in close contact with the inner surface of the dust collection body 241, and the lower surface is in close contact with the upper surface of the internal upper plate 243.

[0158] The adhesive member 248 may be formed in a shape corresponding to the internal upper plate 243.

[0159] The adhesive member 248 includes a hole 2481 that penetrates the dust collection body and is positioned to overlap vertically with the germicidal light irradiation section 2411 of the dust collection body and the germicidal light irradiation section 2431 of the internal upper plate. The germicidal light passes through the hole 2481 and is irradiated into the interior of the dust collection body 241.

[0160] The adhesive member 248 includes a hole 2482 that penetrates the dust collection body's dust inlet 2412 and the internal upper plate's dust inlet 2432, overlapping them vertically. Dust flows into the interior of the dust collection body 241 through the hole 2482.

[0161] Referring to Figures 21 to 23, another embodiment of the present invention, a vacuum cleaner station, includes a gasket 249.

[0162] The gasket 249 is a component that seals the gap between the inlet pipe 244 and the inlet pipe cover 245.

[0163] One side of the gasket 249 is in close contact with the inlet pipe 244, and the other side is in close contact with the inlet pipe cover 245. Referring to Figure 22, the upper surface of the gasket 249 is in close contact with the lower surface of the inlet pipe 244, and the lower surface of the gasket 249 is in close contact with the upper surface of the inlet pipe cover 245.

[0164] An adhesive is applied to the upper surface of the gasket 249, allowing it to be firmly fixed to the inlet pipe 244 by the adhesive.

[0165] The gasket 249 extends along the circumferential direction of the inlet pipe 244. The gasket 249 may be formed in an annular shape with a hollow core.

[0166] The gasket 249 may be formed in a shape that corresponds to the shape of the end of the inlet pipe 244. This allows the upper surface of the gasket 249 to make surface contact with the lower surface of the inlet pipe 244.

[0167] The gasket 249 may be formed from a flexible rubber material. Alternatively, the gasket 249 may be formed from a porous foamed rubber or polystyrene foam material.

[0168] The inlet pipe cover 245 and the gasket 249 may be formed from an expandable material. In this case, the strength of the gasket 249 may be weaker than the strength of the inlet pipe cover 245.

[0169] Referring to Figure 23, the inlet pipe cover 245 can apply pressure to the gasket 249 due to its restoring force. At this time, since the strength of the gasket 249 is weaker than the strength of the inlet pipe cover 245, the inlet pipe cover 245 does not deform, while the gasket 249 can deform. As a result, the gasket 249 deforms and adheres more tightly to the inlet pipe cover 245, completely eliminating the gap between the inlet pipe cover 245 and the gasket 249.

[0170] The inlet pipe 244 may include a gasket insertion groove 2445. The gasket insertion groove 2445 is a component into which the gasket 249 can be securely attached.

[0171] The gasket insertion groove 2445 is formed by being recessed inward at the end adjacent to the inlet pipe cover 245, and at least a portion of the gasket 249 is inserted into it.

[0172] Referring to Figure 23, the gasket insertion groove 2445 may be formed at the lower end of the inlet pipe 244. The gasket insertion groove 2445 may also be formed as an upward recess.

[0173] The gasket 249 may be inserted, at least partially, into the gasket insertion groove 2445.

[0174] The inlet pipe 244 may include a gasket support projection 2446. The gasket support projection 2446 is a component that supports the gasket 249 and maintains the shape of the gasket 249.

[0175] The gasket support projection 2446 protrudes from one side of the inlet pipe and adheres tightly to the inner circumferential surface of the gasket 249.

[0176] Referring to Figure 23, the gasket support projection 2446 may protrude downward from the lower surface of the inlet pipe 244. The gasket support projection 2446 may extend along the inner circumferential surface of the gasket 249. The gasket support projection 2446 may be formed in an annular shape along the inner circumferential surface of the gasket 249.

[0177] The gasket support projection 2446 adheres closely to the inner circumferential surface of the gasket 249 and supports the gasket 249, thereby preventing the weak gasket 249 from easily deforming and reducing its sealing performance.

[0178] According to one embodiment of the present invention, the gasket 249 and the inlet pipe 244 may be formed at the same time.

[0179] The gasket 249 may be bonded to the inlet pipe 244. Specifically, the gasket 249 may be formed together with the inlet pipe 244 by double injection. Alternatively, the gasket 249 may be formed by insert injection into the inlet pipe 244.

[0180] In this case, the gasket 249 is fixed to the inlet pipe 244 and cannot move. A seal is formed when the inlet pipe cover 245 rotates and the upper surface of the inlet pipe cover 245 and the lower surface of the gasket 249 come into close contact.

[0181] According to this embodiment, the gasket 249 is firmly bonded to the inlet pipe 244, which has the effect of improving durability.

[0182] Referring to Figures 24 and 25, according to one embodiment of the present invention, the gasket may be fixed to the inlet pipe by an adhesive member.

[0183] The gasket 249 may be connected to the inlet pipe 244. Specifically, the gasket 249 may be connected to the inlet pipe 244 by an adhesive member 2491.

[0184] Referring to Figure 25, the adhesive member 2491 may be an adhesive tape. Alternatively, the adhesive member 2491 may be an adhesive such as a bond.

[0185] In this case, the gasket 249 is fixed to the inlet pipe 244 and cannot move. A seal is formed when the inlet pipe cover 245 rotates and the upper surface of the inlet pipe cover 245 and the lower surface of the gasket 249 come into close contact.

[0186] According to this embodiment, if the gasket 249 reaches the end of its lifespan or if a part of the gasket 249 separates from the inlet pipe 244, it has the advantage of being easy to replace the gasket 249.

[0187] Referring to Figures 26 and 27, according to one embodiment of the present invention, the gasket 249 may be formed at the same time as the inlet pipe cover 245.

[0188] The gasket is coupled to the inlet pipe cover 245 and can move together with the inlet pipe cover 245. Specifically, the gasket 249 may be formed by double injection together with the inlet pipe cover 245. Alternatively, the gasket 249 may be formed by insert injection into the inlet pipe cover 245.

[0189] In this case, the gasket 249 is fixed to the inlet pipe cover 245 and can move together with the inlet pipe cover. When the inlet pipe cover 245 rotates and the upper surface of the gasket 249 comes into close contact with the lower surface of the inlet pipe 244, a seal is formed.

[0190] According to this embodiment, the gasket 249 is coupled to the inlet pipe cover 245 and can be replaced together with the inlet pipe cover 245, thus providing the advantage of being able to replace the consumable gasket 249 and the inlet pipe cover 245 at the same time.

[0191] The effects and advantages of the vacuum cleaner station 100 according to the present invention, configured as described above, will now be explained.

[0192] The vacuum cleaner station 100 according to the present invention includes an inlet pipe cover 245. The inlet pipe cover 245 is positioned at the end of the inlet pipe 244 and opens and closes the inlet pipe 244. When the dust collection motor is activated, the inlet pipe cover 245 deforms inward to open the inlet pipe 244, and when the dust collection motor stops, it returns to its original shape elastically to close the inlet pipe 244. Therefore, by closing the inlet pipe 244 when the dust collection unit 240 is separated from the vacuum cleaner station 100, it is effective in preventing dust from scattering to the outside, insects from escaping, and unpleasant odors from spreading.

[0193] The end of the inlet pipe 244 has a specific curvature. This curvature may include a first curvature and a second curvature that intersects the first curvature. As a result, the inlet pipe cover 245 deforms in a double manner due to the first and second curvatures, and thus has the effect of firmly sealing the inlet pipe 244 without sagging due to its own weight.

[0194] Furthermore, the dust collection section 240 further includes ribs 1462 that pressurize and deform the inlet pipe cover 245. This allows the inlet pipe cover 245 to deform and adhere closely to the end of the inlet pipe 244, forming a first curvature and a second curvature.

[0195] Furthermore, the inlet pipe cover 245 is open at the front, and side walls 2461 are positioned on both sides of the inlet pipe 244. Air flowing in through the inlet pipe 244 cannot flow backward due to the inlet pipe cover 245, nor can it flow laterally due to the side walls 2461, so it must flow forward. A germicidal light irradiation unit is positioned in front of the inlet pipe 244, and germicidal light is irradiated from it, which also has the effect of killing and sterilizing microorganisms and insects.
