Description

Cleaning robot station

[0001] The present disclosure relates to a station for washing, sterilizing, and drying a pad of a cleaning robot.

[0002] A cleaning robot is a device that automatically cleans an area by autonomously navigating through the area to be cleaned and sucking up foreign substances, such as dust, from the floor surface without user operation.

[0003] Conventional cleaning robots perform floor cleaning using a dry method of sucking up dust from the floor surface. Cleaning robots that perform dry cleaning could not suck up foreign matter adhering to the floor surface or foreign matter larger than a certain size. As a result, there was a problem where foreign matter remained on the floor surface even after the cleaning operation was completed.

[0004] Recently, research and development are underway on cleaning robots capable of not only dry cleaning by sucking up dust but also wet cleaning by wiping the floor surface with water using a pad provided on the bottom surface of the cleaning robot's main body.

[0005] A cleaning robot capable of dry cleaning and wet cleaning received power from a station and performed charging based on docking to a station.

[0006] In addition, as the cleaning robot docked at the station, the cleaning robot's pad was received into the washing chamber, where washing, sterilization, and drying of the pad were performed. For such a cleaning robot, maintenance of the washing chamber provided at the station and the wastewater chamber that stores the wastewater generated by washing the cleaning robot's pad are necessary to ensure the hygiene and cleanliness of both the cleaning robot and the station.

[0007] A typical cleaning robot station includes a water tank containing a wastewater chamber and a water purification chamber, and a sealing structure is required to prevent water inside the tank from leaking out.

[0008] One aspect of the present disclosure provides a station configured to allow the wing portion of a gasket to be deformed from an unfolded shape to a folded shape.

[0144] The water tank (300) may include a cover (320), a gasket (310), and a mounting groove (304) in which the gasket (310) is received and fixed.

[0145] A cover (320) may be provided on the upper part of the water tank (300). The cover (320) may cover the upper part of at least one of the wastewater chamber (302) or the water supply chamber (301). The cover (320) may be attached to the upper part of the water tank (300). The cover (320) may be provided to prevent water stored in the water tank (300) from splashing or leaking out of the water tank (300).

[0146] The cover (320) may include a shielding plate (322). The shielding plate (322) may be provided on the lower side of the cover (320). The shielding plate (322) may be provided to surround the wastewater inlet (307) of the wastewater chamber (302). Accordingly, wastewater sprayed into the interior of the wastewater chamber (302) through the wastewater inlet (307) may collide with the shielding plate (322) and then fall to the lower part of the wastewater chamber (302) by gravity and be stored in the wastewater chamber (302).

[0147] A gasket (310) may be provided between the cover (320) and the water tank (300). The gasket (310) may be provided to seal the space between the cover (320) and the water tank (300). Accordingly, the water tank (300) may include a mounting groove (304) provided on its upper surface to mount the gasket (310). The mounting groove (304) may be formed by being recessed on the upper surface of the water tank (300).

[0148] A mounting groove (304) may be provided in the wastewater chamber (302) and the water supply chamber (301), respectively. The mounting groove (304) may be provided along the edge of the wastewater chamber (302). The mounting groove (304) may be provided along the edge of the water supply chamber (301). The mounting groove (304) may be provided to allow a gasket (310) to be mounted. Accordingly, the gasket (310) may be provided to seal the wastewater chamber (302) and the water supply chamber (301), respectively.

[0149] For example, the mounting groove (304) may be provided in a closed shape. For example, the mounting groove (304) may be provided to have a rectangular perimeter. Accordingly, the gasket (310) may be provided in a closed shape. Accordingly, the gasket (310) may be provided to have a rectangular perimeter.

[0150] The circumference of the gasket (310) may be provided to be approximately the same as the circumference of the mounting groove (304). The shape of the gasket (310) may be provided to correspond to the shape of the mounting groove (304). However, the concept of the present invention is not limited thereto. The gasket (310) may be provided with an elastic material. Accordingly, the gasket (310) may be provided to expand when mounted in the mounting groove (304). Accordingly, the gasket (310) may be strongly coupled to the mounting groove (304).

[0151] The gasket (310) can be provided to seal the inside and outside of the water tank (300). Accordingly, the gasket (310) can be provided to allow wastewater to be easily sucked into the wastewater chamber (302). Specifically, by sealing the inside and outside of the water tank (300), negative pressure can be formed in the wastewater chamber (302).

[0152] The gasket (310) may be provided to have a deformed shape. The gasket (310) may be deformed by contacting the cover (320). The cover (320) may include a protruding rib (321) provided to guide the deformation of the shape of the gasket (310). The protruding rib (321) may be provided on the lower surface of the cover (320). The protruding rib (321) may be provided to protrude from the lower surface of the cover (320). The protruding rib (321) may be provided along the gasket (310). The circumference of the protruding rib (321) may be provided to correspond to the circumference of the gasket (310).

[0153] Generally, gaskets can be classified into wing-type gaskets and hollow-type gaskets. Wing-type gaskets can be used to seal a wastewater chamber (302) in which negative pressure is formed inside. Hollow-type gaskets can be used to seal a water supply chamber (301) in which positive pressure is formed inside.

[0154] A gasket (310) according to one embodiment of the present disclosure may be manufactured to have the shape of a wing-shaped gasket. A gasket (310) according to one embodiment of the present disclosure may be transformed into a hollow gasket by forming a hollow space upon contact with a cover (320). Accordingly, a gasket (310) according to one embodiment of the present disclosure may be used to seal both the wastewater chamber and the water supply chamber.

[0155] A detailed description of the structure and deformation of the gasket (310) will be provided in the following drawings.

[0156] Hereinafter, with reference to FIGS. 10 to 12, the configuration of a gasket (310) according to one embodiment of the present disclosure will be described in detail.

[0157] FIG. 10 is a cross-sectional view taken along line A-A' in FIG. 7 of a water tank according to one embodiment of the present disclosure. FIG. 11 is an enlarged view of the dotted line area in FIG. 10 of a water tank according to one embodiment of the present disclosure. FIG. 12 is an enlarged view of the dotted line area in FIG. 10 when the cover is separated from the water tank according to one embodiment of the present disclosure.

[0158] Referring to FIGS. 10 to 12, the gasket (310) may include a body portion (311) and a wing portion (312).

[0159] The body portion (311) of the gasket (310) may be provided to be received in the mounting groove (304). The body portion (311) may include a support projection (313) provided to be supported on the inner surface (304a) of the mounting groove (304). The support projection (313) may be provided to protrude from the body portion (311) toward the inner surface (304a) of the mounting groove (304). The support projection (313) may be provided to fix the gasket (310) to the inside of the mounting groove (304) by contacting the inner surface (304a) of the mounting groove (304).

[0160] The wing portion (312) may be provided to protrude upward from the upper surface of the body portion (311). The wing portion (312) may be provided to protrude from one side of the body portion (311). At this time, the wing portion (312) may be provided to be bent and extended in the direction of the other side of the body portion (311).

[0161] The wing portion (312) of the gasket (310) may be configured to deform between an unfolded shape and a folded shape. The gasket (310) may be configured to deform when the cover (320) is attached to the water tank (300).

[0162] When the gasket (310) is deformed, the shape of the wing portion (312) can be formed in a folded shape. When the gasket (310) is not deformed, the shape of the wing portion (312) can be formed in an unfolded shape.

[0163] When the shape of the wing portion (312) is in an unfolded state, the gasket (310) can be provided in the shape of a wing-shaped gasket. When the shape of the wing portion (312) is in a folded state, the gasket (310) can be provided in the shape of a hollow gasket.

[0164] Below, the shape and characteristics of the gasket (310) depending on whether the cover (320) and the water tank (300) are combined are described in detail. Referring to FIG. 12, the case in which the wing portion (312) of the gasket (310) is provided in an unfolded shape is described, and referring to FIG. 11, the case in which the wing portion (312) of the gasket (310) is provided in a folded shape is described.

[0165] Referring to FIG. 12, when the gasket (310) is mounted in the mounting groove (304), the wing portion (312) of the gasket may be provided to protrude from the upper surface on one side in the outer direction of the water supply chamber (301) relative to the body portion (311). At this time, the wing portion (312) may be provided in a shape that is bent and extended toward the other side in the inner direction of the water supply chamber (301). When the wing portion (312) of the gasket (310) is provided to face the inner direction of the water supply chamber (301) as described above, the shape of the gasket (310) may be referred to as an inner wing shape.

[0166] For example, the wing portion (312) of the gasket (310) may be provided to protrude from the upper surface on one side of the inner direction of the water supply chamber (301) relative to the body portion (311). At this time, the wing portion (312) may be provided in a shape that is bent and extended toward the other side, which is the outer direction of the water supply chamber (301). When the wing portion (312) of the gasket (310) is provided to face the outer direction of the water supply chamber (301) as described above, the shape of the gasket (310) may be referred to as an outer wing shape.

[0167] In one embodiment of the present invention, the shape of the gasket (310) is illustrated as an example where it is mounted to seal the water supply chamber (301), but the concept of the present invention is not limited thereto. For example, it can be described in the same way even when the gasket (310) is mounted to seal the wastewater chamber (302).

[0168] Referring to FIG. 11, the wing portion (312) of the gasket (310) can be arranged so that when the cover (320) is attached to the water tank (300), the wing portion end (312b) contacts the upper surface of the body portion (311). Accordingly, a hollow (314) can be formed in the upper part of the body portion (311) of the gasket (310).

[0169] The gasket (310) may be provided in the shape of a hollow gasket when the cover (320) is attached to the water tank (300). The gasket (310) may be provided such that a hollow (314) is formed when the upper surface of the water tank (300) and the lower surface of the cover (320) come into contact with each other.

[0170] The wing portion (312) of the gasket can be arranged to be bent at an angle of 90 degrees or more. In other words, the wing portion (312a) can be arranged to be positioned higher than the wing portion (312b). Accordingly, the wing portion (312b) can be arranged to extend downward from the wing portion (312a) while sloping.

[0171] The upper portion of the gasket (310) may be provided such that at least a portion protrudes to the outside of the mounting groove (304). The gasket (310) may be provided such that the wing portion (312a) is positioned to the outside of the mounting groove (304c).

[0172] Accordingly, when the cover (320) is coupled to the water tank (300), the wing portion (312a) of the gasket (310) may come into contact with the lower surface of the cover (320). When the lower surface of the cover (320) comes into contact with the upper surface of the water tank (300), the wing portion (312a) of the gasket (310) may be provided to be received in the mounting groove (304).

[0173] Specifically, as the lower surface of the cover (320) presses the wing portion (312a), the wing portion (312) of the gasket (310) can be bent downward and deformed into a folded shape. Accordingly, the wing portion (312a) of the gasket (310) can be provided at the same height as the mounting groove (304c). Accordingly, the wing portion (312) of the gasket (310) can be provided to be received in the mounting groove (304).

[0174] The gasket (310) can be configured so that when the cover (320) and the water tank (300) are combined, the wing portion (312b) contacts the upper surface of the body portion (311). Accordingly, a hollow (314) can be formed in the gasket (310). Accordingly, the gasket (310) can be configured to have the same sealing effect as a hollow gasket.

[0175] Specifically, when the gasket (310) is provided in the shape of a hollow gasket, the wing portion end (312b) is provided so that it contacts the upper surface of the body portion (311), thereby allowing the wing portion (312) to be less deformed than when the wing portion end (312b) is provided in the shape of a wing-shaped gasket that is spaced apart from the upper surface of the body portion (311).

[0176] Accordingly, the gasket (310) can be used to seal the water supply chamber (301) in which positive pressure is formed inside. A wing-shaped gasket can be used to seal the wastewater chamber (302) in which negative pressure is formed inside.

[0177] That is, as the gasket (310) is provided to have the same sealing effect as a hollow gasket, the gasket (310) can be provided to seal both the water supply chamber (301) where positive pressure is formed and the wastewater chamber (302) where negative pressure is formed.

[0178] Accordingly, the gasket (310) according to one embodiment of the present disclosure is provided such that the deformation of the wing portion (312) is minimized by the wing portion end (312b) coming into contact with the body portion (311), so that even when used to seal the water supply chamber (301), the sealing can be prevented from breaking due to the positive pressure formed inside the water supply chamber (301).

[0179] Generally, when the wing end (312b) is separated from the body part (311), such as in a wing-type gasket, the sealing of the wing-type gasket may break due to strong positive pressure formed inside the water supply chamber (301) when water continues to flow into the water supply chamber (301) due to reasons such as a malfunction of the water supply inlet part (308) of the water supply chamber (301).

[0180] More specifically, when positive pressure is generated inside the water supply chamber (301), the wing portion of the wing-shaped gasket may be pushed and deformed, and accordingly, the degree to which the wing-shaped gasket seals the water tank (300) may be reduced.

[0181] On the other hand, the gasket (310) according to the concept of the present invention is provided such that when the cover (320) is mounted on the water tank (300), the wing end (312b) contacts the body part (311), thereby allowing the water supply chamber (301) to be stably sealed in the same way as a hollow gasket with a hollow formed therein.

[0182] Even if strong positive pressure is generated inside the water supply chamber (301), the wing end (312b) of the gasket (310) is supported on the upper surface of the body (311), thereby preventing the wing (312) from being deformed by being pushed. Accordingly, the gasket (310) can stably seal the water tank (300).

[0183] Meanwhile, the defect rate can be reduced as the gasket (310) of one embodiment of the present invention is manufactured in the shape of a wing-shaped gasket. Since the gasket (310) is provided in the shape of a wing-shaped gasket that does not contain a hollow inside, it can be manufactured in a closed shape during manufacturing.

[0184] In other words, the gasket (310) can be formed in a single process as it is manufactured with a wing-shaped gasket structure. Specifically, the gasket (310) can be integrally formed to have a closed shape during manufacturing. Accordingly, unlike a hollow gasket, the defect rate of the gasket (310) according to one embodiment of the present invention can be reduced during manufacturing.

[0185] A hollow gasket can be manufactured in an open shape due to the formation of a hollow interior, and then formed into a closed shape through a bonding process. A hollow gasket manufactured in an open shape can be formed into a closed shape by joining its two ends together. Since contact failures may occur during the bonding process of joining the ends of the hollow gasket, the defect rate of the hollow gasket may increase during manufacturing.

[0186] If the hollow gasket is not properly joined, the sealing of the water tank (300) may be broken. Accordingly, when the hollow gasket is placed in the mounting groove (304) of the wastewater chamber (302), wastewater from the wastewater chamber (302) may leak out of the wastewater chamber (302).

[0187] On the other hand, the gasket (310) according to one embodiment of the present invention can prevent the sealing of the water tank (300) from breaking as the defect rate during firing is reduced.

[0188] Accordingly, the gasket (310) according to one embodiment of the present disclosure can be made common so as to be applied to both the wastewater chamber (302) and the water supply chamber (301). Accordingly, the manufacturing cost can be reduced compared to using separate gasket structures for the water supply chamber (301) and the wastewater chamber (302). In addition, since the wastewater chamber (302) and the water supply chamber (301) are provided to be sealed by a gasket (310) having the same structural shape, product defects caused by incorrect assembly during the process of assembling the gasket (310) to the water tank (300) can be prevented. Accordingly, the defect rate during the product manufacturing process can be reduced.

[0189] According to one embodiment of the present disclosure, a gasket (310) may be guided to form a hollow (314) by means of a cover (320) and a mounting groove (304).

[0190] The cover (320) may include a protruding rib (321). The protruding rib (321) may be formed on the lower surface of the cover (320). The protruding rib (321) may be provided to contact the gasket (310). The protruding rib (321) may be provided to press the wing portion (312) of the gasket (310) between the wing portion (312a) and the wing portion (312b).

[0191] As a protruding rib (321) is provided on the lower surface of the cover (320), when the wing portion (312) of the gasket (310) is pressed by the cover (320), a hollow (314) can be stably formed in the gasket (310). In other words, the gasket (310) can be guided by the protruding rib (321) so that a hollow (314) is formed.

[0192] The mounting groove (304) may include an inclined surface (304b) on the upper side of the inner surface (304a). The inclined surface (304b) may be provided to be inclined downward as it faces the inner direction of the mounting groove (304). Accordingly, the inclined surface (304b) of the mounting groove (304) may be spaced apart from the lower surface of the cover (320) by a predetermined distance in the inclined direction. Accordingly, a predetermined space may be formed between the inclined surface (304b) and the lower surface of the cover (320). Accordingly, the mounting groove (304) may be provided to guide the formation of a hollow (314) in the gasket (310).

[0193] Specifically, the inclined surface (304b) of the mounting groove (304) can be provided so as to prevent the wing portion (312) of the gasket (310) from getting stuck between the lower surface of the cover (320) and the upper surface of the mounting groove (304) when there is no protruding rib (321) on the lower surface of the cover (320).

[0194] In the case where there is no protruding rib (321) on the lower surface of the cover (320), when the wing portion (312) of the gasket (310) is deformed by the cover (320), the wing portion (312) may slide toward the direction in which the wing portion (312) is bent. When the wing portion (312) slides, the wing portion (312b) may be arranged to come into contact with the inclined surface (304b). At this time, the wing portion (312b) may be guided toward the inside of the mounting groove (304) by the inclined surface (304b) of the mounting groove (304).

[0195] The gasket (310) can be provided so that a hollow (314) is formed when compressed by the cover (320).

[0196] At least a portion of the upper part of the gasket (310) may be provided to protrude outside the opening (304c) of the mounting groove (304). The wing end (312b) of the gasket (310) may be provided to be spaced apart from the upper surface of the body part (311) of the gasket (310).

[0197] The gasket (310) can be arranged so that when the upper part is pressed to the opening (304c) by the cover (320), the wing end (312b) of the gasket (310) comes into contact with the upper surface of the body part (311).

[0198] The gasket (310) may be provided in the shape of a wing-shaped gasket when the cover (320) is separated from the water tank (300). The gasket (310) may be provided in the shape of a hollow gasket when the cover (320) is combined with the water tank (300).

[0199] The gasket (310) can be provided in the shape of a wing-shaped gasket before deformation. The gasket (310) can be provided in the shape of a hollow gasket after deformation.

[0200] Accordingly, it may be easier for the user to attach the cover (320) to the water tank (300). Since the gasket (310) before the cover (320) is attached to the water tank (300) is provided in the shape of a wing-shaped gasket, the deformation of the gasket (310) may be easier. Accordingly, the user can easily attach or detach the water tank (300) and the cover (320).
