Description

Dust collecting device and dust collecting station including same

[0001] Various embodiments of the present disclosure relate to a dust collecting device and a dust collecting station including the same.

[0002] Cleaning devices, such as vacuum cleaners or dust collection stations, are equipped with a dust collection device to collect dust. The dust collection device collects foreign substances such as dust while the cleaning device is in operation, and may have a sealed structure to prevent the collected foreign substances from escaping to the outside for hygiene purposes after operation is complete. For example, the dust collection device may be designed to open in one direction only when foreign substances enter the dust collection bag.

[0003] The dust collection device may include an opening for introducing dust into a dust collection bag and an opening / closing cover for sealing the opening. The opening / closing cover may be composed of a deformable and / or restorable material. The opening / closing cover may be deformed and / or restored during operation of the cleaning device, thereby opening and closing the opening.

[0004] However, with prolonged use of the opening / closing cover, the resilience of the opening / closing cover may deteriorate, preventing it from sufficiently sealing the opening, and a gap may form between the opening and the opening / closing cover. In this case, foreign substances or bacteria may leak through the gap formed between the opening and the opening / closing cover.

[0005] Various embodiments of the present disclosure may provide an opening / closing device including a cover rib that contacts a protruding rib of the dust collector from the outside when the dust collector is sealed.

[0006] A dust collecting device according to one embodiment of the present disclosure may include a support plate including an opening through which dust may enter, a protruding rib extending downward from a periphery of the opening of the support plate, and an opening / closing device connectable to the support plate. The opening / closing device may include an opening / closing cover configured to open / close the opening of the support plate when the opening / closing device is connected to the support plate, and a cover rib configured to protrude from an upper surface of the opening / closing cover and to contact the protruding rib while the opening of the support plate is closed by the opening / closing cover.

[0007] A dust collecting device according to one embodiment of the present disclosure may include a support plate including an opening through which dust may enter, a protruding rib extending downward from a periphery of the opening of the support plate, and an opening / closing device connectable to the support plate. The opening / closing device may include an opening / closing cover configured to open / close the opening of the support plate while the opening / closing device is connected to the support plate, and a rib groove recessed from an upper surface of the opening / closing cover and configured to insert the protruding rib while the opening of the support plate is closed by the opening / closing cover.

[0008] According to various embodiments of the present disclosure, an elastic opening / closing device for opening / closing an opening of a dust collector includes a cover rib, and the cover rib surrounds a protruding rib defining the opening when the opening / closing device is operated and can be in surface contact with the protruding rib. In this case, even if the restoring force of the opening / closing device is reduced due to repeated use of the opening / closing device and a gap is generated between the opening and the opening / closing cover, the gap can be blocked from the outside through the cover rib, and further, the sealing force of the dust collector can be improved through the contact force between the protruding rib and the cover rib.

[0047] The operating principle and embodiments of the present invention will be described with reference to the attached drawings below.

[0048] FIG. 1 is a top perspective view of a dust collector according to one embodiment of the present disclosure.

[0049] FIG. 2 is a bottom perspective view of a dust collector with the dust bag removed, according to one embodiment of the present disclosure.

[0050] FIG. 3 is a bottom perspective view of a support plate according to one embodiment of the present disclosure.

[0051] FIG. 4 is a perspective view of an opening / closing device of a dust collector according to one embodiment of the present disclosure.

[0052] Referring to FIGS. 1 to 4, the dust collector (100) may include a support plate (110), an opening / closing device (120), and a dust bag (130).

[0053] In one embodiment, the support plate (110) may be configured to be detachably fixed within a cleaning device (e.g., a vacuum cleaner, a robot cleaner, or a dust collection station) that sucks up or collects foreign substances such as dust. For example, the support plate (110) may be fixed within the cleaning device or detachably from the cleaning device through various connecting structures, such as a hook structure. In one embodiment, the support plate (110) may have an overall plate shape.

[0054] According to one embodiment, the support plate (110) may include an opening (111) and a protruding rib (112).

[0055] According to one embodiment, the opening (111) may be formed by penetrating the support plate (110). The opening (111) may be formed in a circular shape as illustrated in FIG. 1, but the present disclosure is not limited thereto and may be formed in various shapes, such as a polygon. The opening (111) may function as an entrance through which foreign substances, such as dust, may pass. For example, the opening (111) may communicate the exterior of the dust collecting device (100) with the dust bag (130).

[0056] According to one embodiment, the protruding rib (112) may be formed to extend downwardly (e.g., in the -z-axis direction) along the periphery of the opening (111). For example, the protruding rib (112) may be configured to surround the opening (111) on the lower side of the support plate (110). The protruding rib (112) may, for example, extend from the outer circumferential surface of the opening (111) in a direction perpendicular to the support plate (110). A cross-section of the protruding rib (112) cut along a plane parallel to the support plate (110) (e.g., an xy plane) may correspond to the shape of the opening (111). For example, the protruding rib (112) may have an elliptical shape. For example, at least a portion of the protruding rib (112) may have an arc shape.

[0057] According to one embodiment, the protruding rib (112) may be formed integrally with the support plate (110), but the present disclosure is not limited thereto.

[0058] According to one embodiment, the height of the protruding rib (112) may vary along the perimeter of the opening (111). For example, the height of the protruding rib (112) may gradually increase along the perimeter of the opening (111) from the rear (e.g., in the -x-axis direction) to the front (e.g., in the +x-axis direction). The height of the protruding rib (112) may refer to the length in the vertical direction (e.g., in the -z-axis direction) from the support plate (110) to the lower end of the protruding rib (112). When the dust collector (100) is cut along a vertical plane (e.g., in the xz plane) of the support plate (110), the cross-section of the protruding rib (112) may have a shape that is inclined from the rear to the front. At this time, the angle between the support plate (110) and the lower end of the protruding rib (112) may form an acute angle.

[0059] In one embodiment, the angle between the support plate (110) and the lower end of the protruding rib (112) may vary depending on the maximum height of the protruding rib (112). For example, when the maximum height of the protruding rib (112) increases, the angle between the support plate (110) and the lower end of the protruding rib (112) may also increase. The restoring force of the opening / closing device (120) described below may be adjusted using the maximum height of the protruding rib (112) described above and / or the angle between the support plate (110) and the lower end of the protruding rib (112). For example, when the maximum height of the protruding rib (112) and / or the angle between the support plate (110) and the lower end of the protruding rib (112) increase, the restoring force of the opening / closing device (120) may increase.

[0060] The protruding rib (112) has an inclined structure with an uneven height, so that it can generate a restoring force due to deformation in the opening / closing device (120), and accordingly, the protruding rib (112) and the opening / closing device (120) can be brought into close contact with each other.

[0061] According to one embodiment, the support plate (110) may include a transparent cover (113) that allows light to pass through. The transparent cover (113) may be made of, for example, a material that is impermeable to air. The transparent cover (113) may be provided at a position facing a light source (not shown) (e.g., UV-LED) that irradiates ultraviolet rays. The light source may irradiate light to the dust bag (130) through the transparent cover (113) to kill bacteria inside, thereby preventing bacterial growth within the dust bag (130).

[0062] According to one embodiment, the opening / closing device (120) may be configured to open / close the opening (111) of the support plate (110). For example, the opening / closing device (120) may be configured to open / close the opening (111) of the support plate (110) by having one side coupled to the support plate (110) and the other side rotating around the one side as an axis.

[0063] According to one embodiment, the switch (120) may be formed of a material having elasticity, such as rubber, so as to be elastically deformable. The switch (120) may be formed of, for example, a thermoplastic elastomer (e.g., TPV, thermoplastic vulcanizate) or silicone rubber.

[0064] According to one embodiment, the opening / closing device (120) may include a hinge portion (122) or an opening / closing cover (121).

[0065] According to one embodiment, the hinge portion (122) may be coupled to the support plate (110). In one embodiment, the hinge portion (122) may be inserted into and coupled to the fitting portion (116) of the support plate (110). For example, the upper portion of the hinge portion (122) may be fitted into the fitting portion (116), and the lower portion may be fixed by the fixing portion (114). When the opening and closing device (120) is opened and closed, the opening and closing device (120) may rotate about the hinge portion (122) as an axis since the hinge portion (122) is fixed by the fitting portion (116) and the fixing portion (114).

[0066] According to one embodiment, the opening / closing cover (121) may be connected to the hinge portion (122) to cover the opening portion (111). The opening / closing cover (121) may be formed integrally with the hinge portion (122).

[0067] According to one embodiment, the opening / closing cover (121) may be provided to cover the opening (111) of the support plate (110) and / or the opening (112a) of the protruding rib (112). The opening / closing cover (121) may be provided, for example, to have a shape substantially the same as or larger than the opening (112a) of the protruding rib (112) when in close contact with the protruding rib (112). The opening / closing cover (121) may be provided, for example, to have a horizontal projection area with respect to the support plate (110) when in close contact with the protruding rib (112) that is substantially the same as or larger than the opening (111). When the opening / closing device (120) is opened / closed, communication between the outside of the dust collection device (100) and the dust bag (130) may be maintained or blocked by the opening / closing cover (121).

[0068] According to one embodiment, the dust bag (130) may be provided in the form of a dust collection bag or a dust collection container. The dust bag (130) may be detachably connected to the support plate (110), for example. The dust bag (130) may collect foreign substances such as dust that enter from the outside of the dust collection device (100) through the opening (111) and the protruding rib (112). For example, the dust bag (130) may be provided with a material that is permeable to air but impermeable to foreign substances.

[0069] FIG. 5 is a side view of a dust collection device with an open cover according to one embodiment of the present disclosure.

[0070] FIG. 6 is a side view of a dust collection device with an opening / closing cover closed, according to one embodiment of the present disclosure.

[0071] Referring to FIG. 5, when a predetermined force or pressure is applied in a direction that presses the upper surface (121a) of the opening / closing cover (121) (e.g., downward, in the -z-axis direction), the opening / closing cover (121) is partially deformed or bent by the force or pressure and opens, thereby allowing the outside and inside (e.g., the dust bag (130) of FIG. 1) of the dust collector (100) to communicate with each other. For example, the opening / closing cover (121) may rotate downward (e.g., toward the inside of the dust bag (130)) by the force or pressure and move away from the protruding rib (112).

[0072] When the opening / closing cover (121) is opened, a force (hereinafter, restoring force) may be generated in the opening / closing cover (121) to return to its original state, for example, a state in which the opening / closing cover (121) and the protruding rib (112) are in close contact. Accordingly, in order to open the opening / closing cover (121), the force or pressure pressing the upper surface (121a) of the opening / closing cover (121) must be greater than the restoring force of the opening / closing cover (121).

[0073] The opening cover (121) can be opened when a cleaning device, such as a vacuum cleaner or dust collection station, is in operation.

[0074] Referring to FIG. 6, when the force or pressure applied to the upper surface (121a) of the opening / closing cover (121) is reduced to a certain level or less, the opening / closing cover (121) is closed by being pressed against the protruding rib (112) by the restoring force, thereby blocking the outside and the inside (e.g., the dust bag (130) of FIG. 1) of the dust collector (100) from each other. For example, the opening / closing cover (121) may rotate upward by the restoring force and come closer to the protruding rib (112).

[0075] The opening cover (121) can be closed when a cleaning device, such as a vacuum cleaner or dust collection station, stops operating.

[0076] FIG. 7 is a partial cross-sectional view of a dust collecting device according to one embodiment of the present disclosure.

[0077] FIG. 8 is a perspective view of an opening / closing device according to one embodiment of the present disclosure.

[0078] FIG. 9 is a perspective view of an opening / closing device according to one embodiment of the present disclosure.

[0079] FIG. 10 is a bottom perspective view of an opening / closing device according to one embodiment of the present disclosure.

[0080] Fig. 7 is a partial cross-sectional view of a dust collection device showing the movement path (e.g., path ① or path ②) of pests such as powdery mildew that breed and / or reside inside a dust bag (130).

[0081] In the closed state of the opening / closing device (120), the dust bag (130) is sealed and blocked from the outside, and foreign substances such as dust collected and stored in the dust bag (130) may provide a good environment for breeding and / or living of pests such as powdery mildew inhaled during cleaning. In addition, the restoring force (or sealing force) of the opening / closing cover (121) is reduced by the repeated opening / closing operation of the opening / closing device (120), causing a gap to be generated between the protruding rib (112) and the opening / closing cover (121), and pests such as powdery mildew may leak out of the dust collection device (100) through the gap between the protruding rib (112) and the opening / closing cover (121).

[0082] When the restoring force (or sealing force) of the opening / closing cover (121) is reduced due to repeated opening / closing operations of the opening / closing device (120) and a gap is created between the protruding rib (112) and the opening / closing cover (121), pests such as powder mites may move along the inner surface of the dust bag (130), the lower surface of the support plate (110), and / or the peripheral surface of the protruding rib (112), and then leak out of the dust collection device (100) through the gap between the protruding rib (112) and the opening / closing cover (121), as shown in the movement path ① in FIG. 7. As shown in the movement path ② in Fig. 7, pests such as powder mites may move along the inner surface of the dust bag (130), the lower surface of the support plate (110), and / or the lower surface (121b) of the opening / closing cover (121), and then leak out of the dust collection device (100) through the gap between the protruding rib (112) and the opening / closing cover (121).

[0083] In this way, in order to prevent, trap and / or attract the movement of pests such as powdery mildew mites that breed and / or reside inside the dust bag (130), the dust collection device (100) according to one embodiment of the present disclosure may further include a trap device (or obstacle structure) (141, 142, 143).

[0084] Referring to FIGS. 8 and 9, the trap devices (141, 142) according to one embodiment may be placed on the upper surface (121a) of the opening / closing cover (121). However, the placement position of the trap devices (141, 142) is not limited thereto, and the trap devices (141, 142) may be placed on both the upper surface (121a) and the lower surface (121b) of the opening / closing cover (121), or may be placed on either the upper surface (121a) or the lower surface (121b).

[0085] According to one embodiment, the trap device (141) may be formed by applying an adhesive material to the upper surface (121a) of the opening / closing cover (121). For example, the trap device (141) may be composed of an attractant such as a pheromone or an animal or plant liquid or sugar for attracting pests and an adhesive material such as polybutene and polyisobutylene for catching pests.

[0086] In one embodiment, the trap device (142) may be configured with a structure to impede the movement of pests. For example, the trap device (142) may include a plurality of wires that intersect each other and have a grid pattern.

[0087] Referring to FIG. 10, a trap device (143) according to one embodiment may be formed by applying a fluorescent material or a luminescent material along the edge of the lower surface (121b) of the opening / closing cover (121). For example, the trap device (143) may be composed of an ultraviolet fluorescent material such as fluorescein or rhodamine B to attract pests. For example, the trap device (143) may be composed of a strontium compound to attract pests.

[0088] In this case, by blocking the movement of pests along the surface of the opening / closing cover (121) by the trap device (141, 142, 143), the pests can be prevented from leaking out of the dust collection device (100).

[0089] Fig. 11 is a perspective view of an opening / closing device according to one embodiment of the present disclosure.

[0090] Fig. 12 is a partial cross-sectional view of a dust collecting device according to one embodiment of the present disclosure.

[0091] Referring to FIGS. 11 and 12, an opening / closing device (120) according to one embodiment may include an opening / closing cover (121), a hinge portion (122), and a cover rib (123).

[0092] According to one embodiment, the cover rib (123) may be arranged on the upper surface (121a) of the opening / closing cover (121).

[0093] According to one embodiment, the cover rib (123) may be arranged to surround the protruding rib (112) from the outside and come into contact with the protruding rib (112) when the opening / closing device (120) and the protruding rib (112) of the support plate (110) are in close contact with each other (or when the opening / closing device (120) is closed).

[0094] According to one embodiment, the cover rib (123) may be formed integrally with the opening / closing cover (121). In one embodiment, the cover rib (123) may be formed to protrude vertically from the upper surface (121a) of the opening / closing cover (121). In one embodiment, the cover rib (123) may be formed to extend a predetermined section along the outer circumferential surface (1121) of the protruding rib (112) so as to surround the outer side of the protruding rib (112) when the opening / closing device (120) and the protruding rib (112) of the support plate (110) are in close contact with each other. For example, the cover rib (123) may be formed to extend a predetermined section along the circumferential direction of an imaginary circle (C) having a center of curvature and / or a radius of curvature that is substantially the same as the center of curvature and / or the radius of curvature of the lower end of the protruding rib (112). For example, the cover rib (123) may have an arc shape when the opening / closing device (120) is viewed from above.

[0095] According to one embodiment, the height of the cover rib (123) may change along the outer circumferential surface (1121) of the protruding rib (112) when the opening device (120) and the protruding rib (112) of the support plate (110) are in close contact. For example, the height of the cover rib (123) may change to correspond to the change in the height of the protruding rib (112). For example, when the opening device (120) and the protruding rib (112) of the support plate (110) are in close contact, the height of the portion of the cover rib (123) that comes into contact with the protruding rib (112) may be designed to be substantially the same as or smaller than the height of the portion of the protruding rib (112). For example, as described above, when the height of the protruding rib (112) increases from the rear to the front, the height of the cover rib (123) may also gradually increase along the outer circumference (1121) (or, an imaginary circle (C)) of the protruding rib (112) from the rear to the front.

[0096] According to one embodiment, the cover rib (123) may include an inner surface (123a) that faces and contacts the outer circumferential surface (1121) of the protruding rib (112) of the opening device (120) and the support plate (110) when the protruding rib (112) is in close contact with the opening device (120), and an outer surface (123b) that is opposite to the inner surface (123a).

[0097] As shown in Fig. 12, when the opening / closing device (120) and the protruding rib (112) of the support plate (110) are in close contact, the protruding rib (112) and the cover rib (123) are in surface contact with each other, thereby improving the sealing force between the opening / closing device (120) and the support plate (110), and can compensate for the decrease in sealing force in the case where the restoring force decreases due to repeated opening / closing operations of the opening / closing device (120).

[0098] Figures 13, 14 and 17 illustrate an opening / closing device (220, 320, 420) including a cover rib (223, 323, 423) having a teeth shape and structure. Through the structure of the cover rib (223, 323, 423), interference between the cover rib (223, 323, 423) and foreign substances that occur during the suction operation of the dust collection station (1000) can be reduced.

[0099] Hereinafter, the specific structure of the cover ribs (223, 323, 423) will be described with reference to FIGS. 13 to 17.

[0100] Fig. 13 is a perspective view of an opening / closing device according to one embodiment of the present disclosure.

[0101] Referring to FIG. 13, an opening / closing device (220) according to one embodiment may include an opening / closing cover (121), a hinge portion (122), and a cover rib (223).

[0102] According to one embodiment, the cover rib (223) may be arranged to surround the protruding rib (112) from the outside and come into contact with the protruding rib (112) when the opening / closing device (220) and the protruding rib (112) of the support plate (110) are in close contact (or when the opening / closing device (220) is closed).

[0103] According to one embodiment, the cover rib (223) may include a plurality of teeth portions (2231) and a plurality of recess portions (2232) arranged between the plurality of teeth portions (2231).

[0104] According to one embodiment, a plurality of teeth (2231) may be formed to protrude vertically from the upper surface (121a) of the opening / closing cover (121). In one embodiment, the plurality of teeth (2231) may be arranged to be spaced apart from each other along the outer circumferential surface (1121) of the protruding rib (112) so as to surround the outer side of the protruding rib (112) when the opening / closing device (220) and the protruding rib (112) of the support plate (110) are in close contact with each other. For example, the plurality of teeth (2231) may be arranged to be spaced apart from each other along the circumferential direction of an imaginary circle having a center of curvature and / or a radius of curvature that is substantially the same as the center of curvature and / or the radius of curvature of the lower end of the protruding rib (112).

[0105] According to one embodiment, a plurality of recessed portions (2232) may be formed recessed between a plurality of tooth portions (2231). For example, each of the plurality of recessed portions (2232) may be formed recessed to a predetermined depth from the upper surface of the cover rib (223) between the plurality of tooth portions (2231). In one embodiment, the plurality of recessed portions (2232) may be arranged to be spaced apart from each other along the outer circumferential surface (1121) of the protruding rib (112) so as to surround the outer side of the protruding rib (112) substantially the same as or similar to the plurality of tooth portions (2231) when the opening / closing device (220) and the protruding rib (112) of the support plate (110) are in close contact with each other.

[0106] Comparing the cover rib (123) of the opening / closing device (120) illustrated in FIG. 11 with the cover rib (223) of FIG. 13, when the opening / closing device (220) and the protruding rib (112) of the support plate (110) are in close contact, a plurality of recessed portions (2232) are formed, thereby reducing the contact area between the cover rib (223) and the protruding rib (112), thereby solving the problem of the opening / closing device (220) malfunctioning due to excessive sealing force (for example, the problem of the opening / closing device (220) not being able to open when the dust collection station (1000 of FIG. 22) described below is operated). Consequently, the sealing force of the opening / closing device (220) can be adjusted by adjusting the contact area between the cover rib (223) and the protruding rib (112). For example, the contact area between the cover rib (223) and the protruding rib (112) can be adjusted by the circumferential length of the cover rib (223) (or the curvature of the cover rib (223)), the spacing between the teeth (2231), the width of the teeth (2231), the recessed depth of the recessed parts (2232), the height of the teeth (2231) and / or the thickness of the teeth (2231).
