Background Technology

[0002] Wheeled suitcases are widely used for transporting personal belongings during travel, business trips, or school commutes. Since these suitcases roll over outdoor floors during transport, dirt, dust, and contaminants inevitably adhere to the wheel surfaces. Particularly when moving a suitcase from outdoors to indoors, it is necessary to remove the dirt attached to the wheels to maintain the cleanliness of the indoor floor.

[0003] Traditionally, carrier users primarily used methods such as wiping the wheels directly with wet wipes, tissues, or towels. However, this method had the inconvenience of requiring users to carry separate cleaning supplies, potentially getting their hands dirty, and making it difficult to achieve a sufficient cleaning effect.

[0004] Meanwhile, a wheel washing device for use at construction sites has been developed as a device to remove contaminants from wheels, such as Korean Patent Publication No. 10-2015-0085329. However, methods using air guns have limitations, such as excessive noise and dust dispersion, while methods using water pose a risk of structural damage as the objects to be washed may become wet, and they are difficult to apply to portable or small products due to their reliance on large structures.

[0005] Therefore, there is a continuously growing need for a portable device that can conveniently and hygienically clean small wheels, such as those on suitcases. Prior art literature

However, in describing the operating principles of the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted.

[0040] In addition, the same reference numerals are used for parts that have similar functions and operations throughout the drawing.

[0041] Additionally, when a part of a specification is described as being 'connected' to another part, this includes not only cases where they are directly connected but also cases where they are indirectly connected with other components in between. Furthermore, 'including' a component means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0042] Hereinafter, a portable small wheel automatic cleaning device according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0043] FIG. 1 is a cross-sectional view illustrating a portable small wheel automatic cleaning device according to an embodiment of the present invention, FIG. 2 is a configuration diagram illustrating the configuration of FIG. 1, and FIG. 3 is a conceptual diagram illustrating the concept of a portable small wheel automatic cleaning device according to an embodiment of the present invention.

[0045] As illustrated in FIGS. 1 and 2, a portable small wheel automatic cleaning device (10) according to an embodiment of the present invention includes a body part (100), a tank part (200), and a driving part (300).

[0046] More specifically, as illustrated in FIGS. 1 and 2, a portable small wheel automatic cleaning device (10) according to an embodiment of the present invention comprises a body part (100) having one side open to form a space (101) for inserting a wheel (11), a tank part (200) consisting of a fresh water tank (210) storing cleaning water at the top of the body part and a drainage tank (220) receiving contaminated water generated after cleaning at the bottom of the body part, and a driving part (300) having a roller (310) for rotating the wheel and a brush (320) in contact with the outer surface of the wheel on one side of the fresh water tank.

[0047] Referring to FIGS. 1 and 2, the body portion (100) is formed in a box shape with one side open to form a space (101) inside, and allows a small wheel provided on a travel carrier and a bag capable of moving while storing luggage to be inserted into the space (101). For convenience of explaining the present invention, the wheel (11) is described below as being provided on the carrier.

[0048] And as shown in FIG. 2, a control unit (102) may be further included on one side of the interior of the body unit (100) and may be provided with a PCB board including a control circuit and electronic components capable of driving the driving motor (330) and the rotary motor (520) described later.

[0049] Additionally, although not shown in the drawings of the specification here, a button capable of driving the drive motor (330) and the rotary motor (520) may be provided on the outer surface of the body part (100). Furthermore, the body part (100) may be further provided with a power supply unit capable of receiving external power and a rechargeable battery.

[0050] Additionally, the body part (100) is designed with a waterproof structure to prevent water from penetrating into the control part (102) or into the drive motor (330) and the rotary motor (520), and a generally known waterproof structure can be applied.

[0051] Referring to FIGS. 1 and 2, the tank section (200) consists of a clean water tank (210) that stores washing water at the top of the body section (100) and a drainage tank (220) that receives contaminated water generated after washing at the bottom of the body section (100).

[0052] The term "upper" used throughout the specification may include a position where one of the quadrant points of the wheel (11) faces a vertical direction from the floor when the wheel (11) is inserted into the body part (100). Additionally, the term "lower" may include a position opposite to the upper. To this end, the open side of the body part (100) is positioned so that it faces the wheel (11) while the carrier is lying down, and the fresh water tank (210) is positioned higher than the drainage tank (220).

[0053] The clean water tank (210) is a tank capable of storing wash water and is positioned on the upper part of the body (100) to allow wash water to be sprayed through the nozzle (230) described later. Additionally, an inlet for injecting wash water and a wash water plug (240) for opening and closing the inlet may be provided on one side of the clean water tank (210).

[0054] The drainage tank (220) is a tank that receives contaminated water generated after washing the wheels by being sprayed from the clean water tank (210) at the bottom of the body part (100).

[0055] In particular, the drainage tank (220) includes a sloped surface on one side that slopes downward, collecting the sprayed washing water along the sloped surface and preventing it from leaking out of the internal space (101) of the body part (100).

[0056] Additionally, the drain tank (220) is provided with a drain plug (250) that can open and close the discharge port and spray cleaning water from the clean water tank (210) with the brush (320), and then store the wastewater generated by cleaning the wheel (11) with the brush (320) and then open the drain plug (250) to discharge it through the discharge port.

[0057] As shown in FIGS. 1 and FIGS. 3, the tank portion (200) may further include a nozzle (230).

[0058] The nozzle (230) is installed at the bottom of the clean water tank (210) and sprays cleaning water toward the brush (320) or wheel (11) to wet the brush (320).

[0059] For example, when moving a suitcase outside for travel, dust, dirt, sand, and other contaminants may accumulate on the wheels (11), potentially soiling the floors, carpets, luggage, etc., of the interior space, such as a residential space, hotel, or office. Inspired by the idea of ​​hygienically wiping the wheels (11) with a wet cloth or wet wipes while the suitcase is lying on the floor, cleaning water is sprayed through a nozzle (230) to a brush (320), allowing the wheels (11) to be cleaned with the damp brush (320).

[0060] In particular, although not shown in the specification herein, the nozzle (230) is equipped with a small pump to spray cleaning water in response to the operation of the drive motor (330). Furthermore, if a small pump cannot be provided, it is preferable to discharge cleaning water by gravity so that a small amount of cleaning water can be discharged regardless of the operation of the drive motor (330).

[0061] Referring to FIGS. 1 and 2, the driving unit (300) is equipped with a roller (310) that rotates the wheel (11) on one side of the fresh water tank (210) and a brush (320) that contacts the outer surface of the wheel (11).

[0062] The roller (310) serves to transmit rotational force to the wheel (11) by contacting the outer surface of the wheel (11) when the wheel (11) is inserted into the space (101) of the body part (100).

[0063] For example, as shown in FIG. 3, the wheel (11) is rotated by the rotation of the roller (310) to allow the brush (320) to remove contaminants attached to the wheel (11). Then, the brush (320), which is wet by the cleaning water sprayed from the nozzle (230), comes into close contact with the outer surface of the wheel (11) to clean it.

[0064] At this time, the brush (320), which is dirty due to contaminants on the wheel (11), cleans the outer surface of the wheel (11) with the surface of the brush (320) being cleaned by the continuously supplied cleaning water.

[0065] Referring to FIGS. 2 and 3, the brush (320) is in close contact with the outer surface of the wheel (11) and serves to clean the wheel (11) as described above. To this end, the brush (320) further includes a curved portion (321) and an elastic portion (322).

[0066] The curved portion (321) has a curvature corresponding to the outer surface of the wheel (11), thereby increasing the friction area of ​​the wheel (11) and increasing the cleaning power.

[0067] The elastic part (322) is positioned on the other side of the curved part (321) and serves to push the curved part (321) toward the wheel (11) by means of elastic force.

[0068] Meanwhile, as shown in FIGS. 1 and 2, the driving unit (300) further includes a driving motor (330) that rotates a roller (310) inside the body unit (100).

[0069] The drive motor (330) can be operated by receiving external power or by a battery that can be built into the body part (100). The drive motor (330) has a motor shaft connected to the center of the roller (310) to rotate the roller (310) in one direction, thereby transmitting the rotational force of the roller (310) to the wheel (11) so that the wheel (11) can rotate.

[0070] As illustrated in FIG. 3, the operation process of the portable small wheel automatic cleaning device (10) according to an embodiment of the present invention is described as follows: the fresh water tank (210) is positioned at the top and the drainage tank (220) is positioned at the bottom, and the wheel (11) is inserted into the space (101) of the body part (100). Then, the roller (310) is rotated by pressing a button to drive the drive motor (330).

[0071] At this time, in response to the operation of the drive motor (330), the nozzle (230) sprays cleaning water toward the brush (320) or the wheel (11) to remove contaminants on the wheel (11) and allow it to be cleaned by the wet brush (320).

[0072] In addition, contaminated water generated by removing contaminants from the wheel (11) falls and collects along the slope of the drainage tank (220) and moves into the interior of the drainage tank (220).

[0073] FIG. 4 is a cross-sectional view illustrating a portable small wheel automatic cleaning device according to another embodiment of the present invention.

[0074] As illustrated in FIG. 4, a portable small wheel automatic cleaning device (20) according to another embodiment of the present invention comprises a body part (100) having one side open to form a space (101) for inserting a wheel (11), a clean water tank part (400) having a clean water tank (210) that stores cleaning water at the bottom of the body part, and a brush driving part (500) including a roller (310) that rotates the wheel (11) at the upper inner side of the body part (100), and a brush belt (510) having one side in contact with the inner wall of the clean water tank (210) and in contact with the outer surface of the wheel (11), and the other side extending into the interior of the clean water tank (210).

[0075] Here, the body part (100) is identical to the body part of the previously described embodiment, but a fresh water tank (210) is placed at the location of the drainage tank (220). And the control part (102) described above is provided in the same way, so a detailed description is omitted.

[0076] Additionally, the body part (100) can be modified to lower the height of the body part (100) by positioning the fresh water tank (210) at the bottom of the body part (100). To achieve this, the drive motor (330) can be positioned on the other side inside the body part (100), and the roller (310) can be positioned corresponding to the drive motor (330).

[0077] And, replacing the elastic part (322) shown in the embodiment, a stopper (530) made of a soft material is provided on the inner side of the body part (100) to restrict further insertion of the wheel (11) into the space (101).

[0078] Referring to FIG. 4, the clean water tank section (500) is composed of a clean water tank (210) that stores wash water inside, and a wash water plug (240) is provided on one side of the clean water tank (210) as in the above-described embodiment to inject or discharge wash water.

[0079] This fresh water tank section (500) is equipped with a rotating shaft (401) on both sides inside the fresh water tank (210) and has a brush belt (510) axially connected to the rotating shaft (401) to apply tension to the brush belt (510).

[0080] Referring to FIG. 4, the brush drive unit (500) further includes a roller (310), a brush belt (510), and a rotary motor (520).

[0081] The roller (310) is the same as the previously described embodiment, so a detailed description is omitted.

[0082] The brush belt (510) is formed as a band that extends in one direction and forms a single unit, and is positioned so that one side is in close contact with the lower outer surface of the wheel (11).

[0083] At this time, one side in the longitudinal direction is located on one side of the fresh water tank (210), and the other side in the longitudinal direction is located inside the fresh water tank (210), and rotates by the drive of the rotary motor (520). After cleaning the wheel (11) by the rotation of the brush belt (510), it moves into the inside of the fresh water tank (210) to remove contaminants attached to the brush belt (510), and after cleaning, the outer surface of the wheel (11) is cleaned again.

[0084] Additionally, when the brush belt (510) moves to the fresh water tank (210) after washing the wheel (11), tension is applied by the rotating shaft (401) provided inside the fresh water tank (210), so that one side of the brush belt (510) located on one side of the fresh water tank (210) is taut and adheres to the outer surface of the wheel (11) to generate friction.

[0085] Referring to FIG. 4, the rotary motor (520) is installed inside the other side of the body part (100) to rotate the brush belt (510) in the opposite direction to the rotation direction of the roller (310) and to move it to the clean water tank (210) so that the wheel (11) and the brush belt (510) can be cleaned, and it is also possible to arrange them as a pair as shown in the drawings of the specification herein.

[0086] The rotary motor (520) causes the brush belt (510) to rotate in a direction different from the rotation direction of the wheel (11), thereby enabling more removal of contaminants attached to the wheel (11). Additionally, by wiping the wheel (11) with water after it is submerged in the fresh water tank (210), the cleaning time of the wheel (11) can be reduced while increasing the effectiveness.

[0087] FIG. 5 is a cross-sectional view illustrating the concept of a portable small wheel automatic cleaning device according to another embodiment of the present invention in a planar cross-section.

[0088] As illustrated in FIG. 5, a portable small wheel automatic cleaning device (30) according to another embodiment comprises a body part (100) having one side open to form a space (101) for inserting a wheel, a water tank part (200) having a water tank (210) that stores cleaning water at the bottom of the body part, and a driving brush part (600) having a brush belt (510) arranged at a predetermined angle with respect to a straight line of the wheel on one side of the water tank, wherein one side of the driving brush part (600) is located on one side of the water tank (210) and contacts the outer surface of the wheel (11), and the other side is located inside the water tank (210).

[0089] The body part (100) and the fresh water tank part (200) are identical to the previously described embodiment, so a detailed description is omitted.

[0090] Referring to FIG. 5, the drive brush unit (600) arranges the brush belt (510) at a predetermined angle relative to a straight line in which the wheels (11) are arranged, and connects the brush belt (510) to a rotary motor (520) provided on one side of the fresh water tank (210) so that it rotates by the drive of the rotary motor (520).

[0091] At this time, the wheel (11) is made to rotate at a speed slower than the rotational speed of the brush belt (510) by means of a brush belt (510) that is arranged at a predetermined angle relative to the straight line of the wheel (11). Then, the brush belt (510), which moves to one side of the clean water tank (210) after being submerged in the clean water tank (210), washes the outer surface of the wheel (11) that rotates relatively slowly.

[0092] As shown in FIG. 5, the driving brush part (600) may further include a guide part (601).

[0093] The guide section (601) is provided with a wall on one side of the body section (100) that gradually narrows the gap toward the other side of the body section (100) to guide the insertion of the wheel (11) into the space (101).

[0094] Additionally, the guide section (601) can prevent the wheel (11) from shaking due to oscillation when the wheel (11) or the brush belt (510) is rotated, thereby allowing the wheel (11) to be cleaned more thoroughly.

[0095] As explained above, the detailed description of the present invention describes preferred embodiments of the invention; however, this is merely an illustrative description of the best embodiments of the invention and is not intended to limit the invention. Furthermore, it is obvious that anyone skilled in the art to which the present invention pertains can make various modifications and imitations within the scope of the technical concept of the present invention without departing from it.

[0096] Accordingly, the scope of the present invention is not limited to the embodiments described above but may be implemented in various forms of embodiments within the scope of the appended claims. Furthermore, it is deemed that the scope of the claims of the present invention includes various modifications that are possible by anyone with ordinary knowledge in the technical field to which the invention belongs, without departing from the essence of the invention claimed in the claims.
