[0040] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings. Based on the principle that the inventor can appropriately define the concepts of terms to best explain his or her invention, they should be interpreted in a way that aligns with the technical spirit of the present invention.

[0041] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, and it should be understood that there may be various equivalents and modified examples that can replace them at the time of this application.

[0042] FIG. 1 and FIG. 2 are perspective views showing the overall shape of a multi-guide device (1) according to one embodiment of the present invention, and FIG. 3 and FIG. 4 are exploded perspective views of the multi-guide device (1) of FIG. 1.

[0043] In the embodiment of the present invention, the X-axis and Y-axis directions shown in the drawing may mean the radial direction of the multi-guide device (1) described later, and the Z-axis direction may mean the vertical direction perpendicular to both the X-axis direction and the Y-axis direction.

[0044] Referring to FIGS. 1 to 4, a multi-guide device (1) according to one embodiment of the present invention may include a guide body (10) and a multi-guide part (20). In this case, the multi-guide device (1) may be a multi-guide device for washing machine drainage provided in a drain of a space where a washing machine (not shown) is installed. In FIG. 1, the drain described later is denoted by reference symbol 'B'.

[0045] The above guide body (10) has a flow space formed therein so that sewage can flow, and the lower end can be connected to a drain. At this time, the guide body (10) is connected vertically to the drain, so that sewage discharged from the washing machine can be easily guided through the drain. As an example, the guide body (10) may have an overall shape that is approximately cylindrical, but is not limited thereto, and may be configured in the shape of a polygonal column of a triangular shape or larger.

[0046] The above multi-guide part (20) may be provided on the upper part of the guide body (10). In addition, the multi-guide part (20) may include a plurality of coupling holes (22) having different diameters so that pipes (not shown) of different diameters of the washing machine can be coupled. In this case, when the pipes are coupled to the coupling holes (22), sewage discharged through the pipes can flow into the flow space of the guide body (10).

[0047] At this time, the multi-guide part (20) may have a different material from the guide body (10).

[0048] As an example, the guide body (10) is made of a hard synthetic material including plastic or the like, so that a flow space through which sewage can flow can be stably formed.

[0049] On the other hand, the multi-guide part (20) may include a flexible material (e.g., rubber, silicone, etc.) so that the piping of the washing machine can be connected to the coupling part (22). That is, the multi-guide part (20) may be composed of a material that is more flexible than the guide body (10).

[0050] Accordingly, pipes of various diameters can be connected to a single multi-guide unit (20), so that even if the diameter of the pipe changes, the sewage drainage function can be stably performed without replacing the multi-guide device (1). In addition, since the multi-guide unit (20) includes a flexible material, even if the diameter of the pipe does not completely match the diameter of the coupling member (22), the pipe can be easily connected to the multi-guide unit (20) without damage to the multi-guide unit (20).

[0051] According to this implementation configuration, a separate flow space can be provided in which sewage discharged from the washing machine can flow through a multi-guide device (1) vertically connected to the drain of the space where the washing machine is installed, so there is an advantage in that sewage can be stably discharged through the drain without leaking into the space where the washing machine is installed.

[0052] In addition, according to the multi-guide device (1) of the present invention, there is an advantage in that the sewage can be easily discharged to the drain side regardless of the diameter of the pipe of the washing machine.

[0053] Referring to FIG. 1, FIG. 3 and FIG. 4, the multi-guide section (20) may further include a side section (24).

[0054] The above side portion (24) can be configured to surround the guide coupling portion (11) formed at the upper end of the guide body (10).

[0055] Specifically, the guide coupling portion (11) may be configured to be recessed to a predetermined depth radially inward from the upper outer surface of the guide body (10). In addition, the side portion (24) may be formed at the radially outer end of the multi-guide portion (20) and configured to extend downward.

[0056] That is, since the side part (24) of the multi-guide part (20) made of a material more elastic than the guide body (10) can wrap around the upper part (guide coupling part (11)) of the guide body (10), when sewage flows into the flow space within the guide body (10) from the pipe coupled to the coupling port (22), sewage can be prevented from leaking into the gap between the guide body (10) and the multi-guide part (20).

[0057] Figure 5 is a cross-sectional view taken along the AA' direction of Figure 1.

[0058] Referring to FIG. 5, the guide body (10) may further include a first step portion (12) and a first sewage discharge guide portion (13).

[0059] The first step portion (12) may be formed to extend radially inwardly from a position adjacent to the lower end of the guide body (10). Specifically, the first step portion (12) may be formed to extend parallel to the radially inward direction of the guide body (10) from the inner surface of the guide body (10). This first step portion (12) may be a portion that primarily comes into contact with sewage as sewage discharged through the pipe of the washing machine coupled to the coupling member (22) flows toward the drain within the flow space of the guide body (10).

[0060] The first sewage discharge guide portion (13) may extend downwardly from the first step portion (12) toward the drain hole (10a) for discharging sewage toward the drain outlet. In addition, the first sewage discharge guide portion (13) may be configured to guide the flow of sewage toward the drain hole (10a).

[0061] At this time, the drain hole (10a) may be formed in the central portion of the lower part of the guide body (10). In addition, the diameter of the first step portion (12) may be larger than the diameter of the first sewage discharge guide portion (13).

[0062] That is, sewage discharged from the pipe and randomly introduced into the flow space of the guide body (10) is firstly vertically contacted with the first step portion (12), and then secondly, the flow is smoothly guided along the first sewage discharge guide portion (13) formed to have a smaller diameter than the first step portion (12) and extending downwardly toward the lower center of the guide body (10) so that the sewage can be discharged into the drain through the drain hole (10a).

[0063] According to this implementation configuration, the flow of sewage toward the drain can be given directionality within the flow space of the guide body (10) (e.g., the entire flow of sewage is concentrated in the lower central part of the flow space of the guide body (10), so that sewage can be discharged toward the drain more quickly.

[0064] Referring again to FIG. 5, the guide body (10) may further include a second step portion (14) and a second sewage discharge guide portion (15).

[0065] The second step portion (14) may be formed to be connected to the first sewage discharge guide portion (13) and extend radially inwardly of the guide body (10). Specifically, the second step portion (14) may be formed to extend parallel to the inner surface of the guide body (10) radially inwardly of the guide body (10). This second step portion (14) may be a portion that primarily comes into contact with sewage flowing through the first sewage discharge guide portion (13).

[0066] The second sewage discharge guide portion (15) may extend, at least in part, from the second step portion (14) in a downwardly inclined manner toward the drain hole (10a). In addition, the second sewage discharge guide portion (15) may be configured to guide the flow of sewage toward the drain hole (10a).

[0067] And, the diameter of the second step portion (14) may be larger than the diameter of the second sewage discharge guide portion (15).

[0068] That is, the sewage flowing through the first sewage discharge guide part (13) first comes into contact with the second step part (14) in the vertical direction, and then flows smoothly along the second sewage discharge guide part (15) which is formed to have a smaller diameter than the second step part (14) and at least a portion thereof extends downwardly toward the lower center of the guide body (10) so that it can be discharged into the drain through the drain hole (10a).

[0069] According to this implementation configuration, the flow of sewage toward the drain can be given more directionality within the flow space of the guide body (10), so that sewage can be discharged toward the drain more quickly.

[0070] In addition, when viewed from the top and bottom of the guide body (10), the diameters of the first step portion (12), the first sewage discharge guide portion (13), the second step portion (14), and the second sewage discharge guide portion (15), which guide the flow of sewage within the flow space of the guide body (10), may become smaller as they go toward the drain hole (10a), so that the overall flow of sewage may be concentrated more toward the drain hole (10a) located at the lower center of the flow space of the guide body (10) as they go lower inside the flow space.

[0071] In particular, the second sewage discharge guide part (15) may include a vertical part (15a) and an inclined part (15b). At this time, the second sewage discharge guide part (15) may be positioned closer to the drain hole (10a) than the first sewage discharge guide part (13).

[0072] The above vertical portion (15a) may be configured to extend vertically downward from the second step portion (14). That is, the second sewage discharge guide portion (15) may not be configured to slope downward entirely as in FIG. 5, but a portion thereof may extend vertically downward.

[0073] The above-mentioned inclined portion (15b) may be configured to extend downwardly from the vertical portion (15a) toward the drain hole (10a) in a slanted manner, thereby guiding the flow of sewage toward the drain hole (10a).

[0074] According to this implementation configuration, sewage can rapidly fall toward the drain hole (10a) through the vertical portion (15a) of the second sewage discharge guide portion (15) at a position adjacent to the drain hole (10a), and the sewage can be guided to flow toward the drain hole (10a) through the inclined portion (15b) at a position as close as possible to the drain hole (10a). Accordingly, there is an advantage in that the flow of sewage can be quickly maintained while guiding the flow further toward the drain hole (10a).

[0075] Referring to FIGS. 2 to 5, the guide body (10) may further include a drain connection cap (16).

[0076] The above drain connection cap (16) can be configured to vertically connect the lower part of the guide body (10) to the drain.

[0077] In one embodiment, the drain coupling cap (16) may be coupled to the guide body (10) in a form that surrounds the outer surface of the drain (10a) (e.g., in a screw-coupled form). At this time, the lower end of the drain coupling cap (16) may be provided with at least one insertion portion (16a) that is formed to extend vertically downward.

[0078] And, the above insertion part (16a) can be inserted vertically into the drain port to vertically connect the lower part of the guide body (10) to the drain port.

[0079] According to this implementation configuration, since the guide body (10) can be stably vertically coupled to the drain, sewage can stably flow through the flow space of the guide body (10) and be discharged toward the drain.

[0080] Figure 6 is a drawing showing a multi-guide device (2) according to the second embodiment of the present invention.

[0081] Since the multi-guide device (2) according to the present embodiment is similar to the multi-guide device (1) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0082] Referring to Fig. 6, in the multi-guide device (2), a plurality of cut portions (22a) may be provided in the coupling portion (22) of the multi-guide portion (20).

[0083] The above-described plurality of cut portions (22a) may be configured to open the joint (22) by being pressed downward according to the pressure applied to the cut groove (22b) when the pipe of the washing machine is inserted into the joint (22). At this time, the cut groove (22b) may be formed at a portion of the joint (22) where different cut portions (22a) face each other.

[0084] Additionally, the plurality of cut portions (22a) may be configured to close the joint (22) by returning to its original state by elastic force when the piping of the washing machine is separated from the joint (22). As an example, the cut portions (22a) may include a material having excellent elastic restoring force.

[0085] Fig. 7 is a drawing showing a multi-guide device (3) according to a third embodiment of the present invention.

[0086] Since the multi-guide device (3) according to the present embodiment is similar to the multi-guide device (1) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0087] Referring to Fig. 7, in the multi-guide device (3), the guide body (10) may be configured such that the lower end is fitted into the upper side of the drain when the drain is structured to protrude a predetermined height from the space where the washing machine is installed. In this embodiment, the drain may be configured in a cylindrical shape having a predetermined height.

[0088] Specifically, the insertion portion (16a) of the aforementioned drain coupling cap (16) is vertically inserted into the cylindrical drain, thereby vertically coupling the lower end of the guide body (10) to the drain.

[0089] Fig. 8 is a drawing showing a multi-guide device (4) according to the fourth embodiment of the present invention.

[0090] Since the multi-guide device (4) according to the present embodiment is similar to the multi-guide device (1) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0091] Referring to Fig. 8, in the multi-guide device (4), the multi-guide part (20) may include an internal pipe (26) that extends from the coupling member (22) and is configured to have a diameter that increases toward the bottom.

[0092] At this time, the internal pipe (26) can be configured so that a part (part 'a' of FIG. 8) faces the first step portion (12) and the remaining part (part 'b' of FIG. 8) faces the drain hole (10a).

[0093] That is, a part of the internal pipe (26) is configured to face the first step portion (12) so that some of the sewage can be guided to flow densely into the drain hole (10a) along the first step portion (12), the first sewage discharge guide portion (13), the second step portion (14), and the second sewage discharge guide portion (15), the diameter of which becomes smaller sequentially as it goes down the guide body (10).

[0094] Meanwhile, the remaining area of ​​the internal pipe (26) is configured to directly face the drain hole (10a) located at the lower center of the flow space of the guide body (10), so that the remaining portion of the sewage can be guided to directly face the drain hole (10a).

[0095] That is, in the present embodiment, a separate internal pipe (26) is provided within the flow space of the guide body (10), and the diameter of the internal pipe (26) increases as it goes downward, and a part of the internal pipe (26) and the remaining part can be configured to face different parts (the first step portion (12), the drain hole (10a)) within the flow space of the guide body (10), so that more diversity can be provided to the flow of sewage within the flow space.

[0096] FIG. 9 is a drawing showing a sewer trap (30) provided in a drain where the multi-guide device (1) of FIG. 1 is installed, and FIG. 10 is a partial cross-sectional view of the sewer trap (30) of FIG. 9.

[0097] Referring to FIGS. 9 and 10, a sewer trap (30) may be connected to the lower end of the guide body (10) and arranged in a drain to guide the flow of sewage.

[0098] Specifically, the sewer trap (30) may include a body (100), an upper mounting portion (200), and a lower sealing portion (300).

[0099] The body (100) may have a flow space formed therein so that sewage can flow. As an example, the body (100) may have an overall shape that is approximately cylindrical, but is not limited thereto and may be configured in the shape of a polygonal column of a triangular shape or larger.

[0100] A body (100) can be mounted on the upper mounting portion (200). In addition, the upper mounting portion (200) can be placed on a drain, more specifically, on a drain wall (P) provided on the inlet side of the drain. Specifically, a step portion (210, see FIG. 11) is formed on the radial center side of the upper mounting portion (200) so that the upper end of the body (100) can be mounted thereon. At this time, the diameter of the upper mounting portion (200) can be larger than the diameter of the body (100). In addition, sewage flowing into the upper mounting portion (200) can flow into the flow space of the body (100) mounted on the step portion (210).

[0101] The above filter unit (700) may be placed in a drain, more specifically, on the drain wall (P). In addition, the filter unit (700) may be provided on the upper portion of the upper mounting unit (200). In addition, the filter unit (700) may be formed with a plurality of holes (H) to filter foreign substances (e.g., hair, etc.) contained in sewage.

[0102] Meanwhile, the filter unit (700) may be configured to have a plurality of holes (H) formed to guide sewage to flow into the upper receiving unit (200).

[0103] According to this embodiment of the present invention, when sewage flows into the upper receiving portion (200) through the filter portion (700), foreign substances in the sewage can be filtered through the plurality of holes (H) of the filter portion (700) and then flow into the flow space of the body (100) through the upper receiving portion (200), so that sewage can be discharged more stably without blockage of the flow space of the body (100) by foreign substances.

[0104] In one embodiment, the filter unit (700) may be positioned below a drain cover (C) that covers the inlet of the drain. This drain cover (C) may be positioned on the drain wall (P).

[0105] In particular, the insertion portion (16a) of the drain coupling cap (16) provided at the bottom of the guide body (10) is coupled to the drain cover (C), so that the bottom of the guide body (10) can be vertically coupled to the drain trap (30) and the drain. Accordingly, sewage passing through the inside of the guide body (10) can be discharged through the drain via the drain trap (30).

[0106] Referring to Fig. 10, the filter unit (700) may be arranged on the upper portion of the upper mounting portion (200) to form a flow space through which sewage can flow between the upper surface of the upper mounting portion (200) and the lower portion of the filter unit (700). At this time, the upper surface of the upper mounting portion (200) and the lower portion of the filter unit (700) may be spaced apart from each other by a predetermined distance in the vertical direction.

[0107] That is, sewage from which foreign substances have been filtered through the plurality of holes (H) of the filter unit (700) can flow through a flow space between the upper surface of the upper holding unit (200) and the lower side of the filter unit (700) and then flow toward the upper holding unit (200).

[0108] In one embodiment, a plurality of holes (H) of the filter unit (700) may be formed on the filter unit (700) with the same predetermined size, and may be arranged spaced apart from each other at a predetermined interval.

[0109] Accordingly, when sewage flows into the upper receiving portion (200) through the filter portion (700), sewage that was flowing rapidly from the outside can flow into the upper receiving portion (200) uniformly while passing through a plurality of holes (H) of the filter portion (700) having uniform sizes and uniform spacings.

[0110] According to the sewer trap (30) of this embodiment, sewage that has passed through the filter unit (700) can be uniformly introduced into the upper mounting unit (200), so that the sewage can be guided to be introduced into the flow space of the body (100) by more stably applying rotational force to the sewage through the second rotation guide unit (220) of the upper mounting unit (200) described later.

[0111] Referring to FIG. 10, the body (100) may further include a first rotation guide portion (120).

[0112] The first rotation guide part (120) may be configured to guide the flow of sewage in the flow space of the body (100). In addition, a plurality of first rotation guide parts (120) may be provided along the inner circumferential surface (inner surface) of the body (100).

[0113] Additionally, the upper mounting portion (200) may further include a second rotation guide portion (220).

[0114] The second rotation guide part (220) may be configured to guide the flow of sewage so that the sewage flows into the body (100). In addition, at least one second rotation guide part (220) may be provided along the upper mounting part (200). As an example, at least one second rotation guide part (220) may be provided along the upper surface of the upper mounting part (200).

[0115] As described above, the upper end of the body (100) can be seated on a step portion (210, see FIG. 11) formed on the radial center side of the upper mounting portion (200). At this time, the second rotation guide portion (220) can be formed to extend radially from the step portion (210) to the outer end of the upper mounting portion (200) on the upper surface of the upper mounting portion (200).

[0116] And, the sewage flowing into the upper mounting portion (200) can be guided in flow by the second rotating guide portion (220) and can flow into the flow space of the body (100) placed on the radial center side of the upper mounting portion (200).

[0117] According to this implementation configuration, since a rotational force can be applied to the sewage before it flows into the flow space of the body (100), a stronger rotational force can be additionally applied to the sewage to which the rotational force has been applied by the second rotational guide part (220) within the body (100) by the first rotational guide part (120). Accordingly, the sewage can be discharged more quickly toward the drain.

[0118] In addition, the plurality of holes (H) of the filter unit (700) may be configured to face the upper surface of the upper mounting unit (200) on which the second rotation guide unit (220) is formed in the vertical direction. Accordingly, by applying rotational force to the sewage that has passed through the filter unit (700) through the second rotation guide unit (220) of the upper mounting unit (200), the sewage can be guided to flow into the flow space of the body (100).

[0119] Referring to FIGS. 9 and 10, the area on the horizontal plane (XY plane) of the filter unit (700) can be configured to be larger than the area on the horizontal plane (XY plane) of the upper surface of the upper mounting unit (200).

[0120] Specifically, the filter unit (700) may be configured to cover the entire upper surface of the upper mounting unit (200). As an example, the cross-sectional shape of the filter unit (700) on the horizontal plane (XY plane) may be approximately rectangular, but is not limited thereto.

[0121] In this way, since the area of ​​the filter unit (700) can be configured to be relatively larger than the area of ​​the upper surface of the upper mounting unit (200) facing in the vertical direction, sewage that has passed through the filter unit (700) can flow in more quickly and intensively when flowing into the upper mounting unit (200).

[0122] Hereinafter, with reference to FIGS. 11 to 19, other configurations of the sewer trap (30) will be examined in more detail. At this time, in FIGS. 11 to 19, the illustration of the filter section (700) described above will be omitted.

[0123] FIG. 11 is a drawing showing a part of the sewer trap (30) of FIG. 9, FIG. 12 is a perspective view showing the sewer trap (30) of FIG. 11 from below, FIG. 13 is an exploded perspective view of the sewer trap (30) of FIG. 11, and FIG. 14 is a drawing showing the sewer trap (30) of FIG. 11 from above.

[0124] Referring to FIGS. 11 to 14, the body (100) may include a main guide portion (110). The main guide portion (110) may be configured to guide the flow of sewage in a flow space. In particular, the main guide portion (110) may be configured to have a portion having a curved surface to guide the flow of sewage. That is, sewage flowing into the body (100) may be guided through the curved surface of the main guide portion (110) and discharged into a drain.

[0125] The above lower sealing portion (300) can move along the main guide portion (110) to open the lower portion of the body (100) when a load of sewage is applied. At this time, sewage flowing into the flow space of the body (100) can flow toward the lower sealing portion (300).

[0126] In addition, the lower sealing portion (300) may be configured to move along a part of the body (100), specifically the main guide portion (110), by magnetic force when the load of the sewage applied to the lower sealing portion (300) is released, thereby sealing the lower portion of the body (100). Here, the magnetic force-related configuration that moves the lower sealing portion (300) to seal the lower portion of the body (100) when the load of the sewage is released will be examined in more detail in the related description to be described later.

[0127] According to this embodiment of the present invention, sewage can be discharged into the drain while a rotational force is applied to the sewage through the main guide portion (110) having a curved surface, so that sewage can be discharged more quickly and stably.

[0128] In addition, when the load of sewage is applied, the lower sealing part (300) is moved to open the lower part of the body (100) so that the sewage can be quickly discharged into the drain, and when the load of sewage applied to the lower sealing part (300) is released, the lower sealing part (300) seals the lower part of the body (100) so that the foul odor coming up from the drain can be effectively blocked.

[0129] Fig. 15 is a drawing showing a body (100) equipped in the sewer trap (30) of Fig. 11, Fig. 16 is a drawing showing an upper mounting part (200) equipped in the sewer trap (30) of Fig. 11, Fig. 17 is a drawing showing a lower sealing part (300) equipped in the sewer trap (30) of Fig. 11, and Fig. 18 is a cross-sectional view of the sewer trap (30) of Fig. 14 taken vertically from approximately the center. At this time, Fig. 18 is a drawing showing the sewer trap (30) of Fig. 14 in cross-section with respect to the YZ plane.

[0130] Referring to FIGS. 11 to 18, the main guide portion (110) may further include a side guide portion (112). In one embodiment, a portion (110a) of the main guide portion (110) may be configured to extend longitudinally in the vertical direction. In particular, the portion (110a) of the main guide portion (110) may be positioned approximately at the center of the flow space of the body (100) when viewed in the radial direction.

[0131] The above-mentioned side guide portion (112) may be formed by being recessed radially inward on the outer surface of a portion (110a) of the main guide portion (110) that is configured to extend in a vertical direction. This side guide portion (112) may also be configured to extend in a vertical direction along the outer surface of a portion (110a) of the main guide portion (110).

[0132] Additionally, the lower sealing portion (300) may include an insertion guide portion (312).

[0133] This insertion guide part (312) may be configured to guide the movement of the lower sealing part (300) in the up-and-down direction through the side guide part (112) as the load of the sewage is applied by being inserted into the side guide part (112). To this end, the insertion guide part (312) may be formed to protrude a predetermined length from the inner circumferential surface (inner surface) of the lower sealing part (300) toward the radial center of the lower sealing part (300) in correspondence with the shape of the side guide part (112).

[0134] In this way, since the movement of the lower sealing portion (300) in the up-and-down direction is guided along the side guide portion (112) provided in a part (110a) of the main guide portion (110) located approximately in the center of the flow space of the body (100), the opening or closing action of the lower sealing portion (300) on the lower part of the body (100) can be performed more stably as the load of the sewage is applied to the lower sealing portion (300).

[0135] Referring to FIGS. 12, 13, 17 and 18, the lower sealing portion (300) can be configured to have a diameter that decreases as it goes upward.

[0136] That is, the lower sealing portion (300) may be configured so that its diameter on the horizontal plane (XY plane) becomes smaller as it goes upward. In addition, a protrusion (310) formed to protrude in the vertical direction may be provided at the upper end of the lower sealing portion (300).

[0137] Meanwhile, the insertion guide portion (312) may be formed on the inner surface of the protrusion portion (310). Specifically, the insertion guide portion (312) may be formed by protruding a predetermined length from the inner surface of the protrusion portion (310) toward the radial center of the protrusion portion (310) in correspondence with the shape of the side guide portion (112).

[0138] In this way, since the lower sealing portion (300) is configured so that the diameter on the horizontal plane becomes smaller as it goes upward, the overall shape of the lower sealing portion (300) is configured to have a roughly downward slope as it goes downward, so that sewage flowing into the lower sealing portion (300) through the flow space of the body (100) can be discharged more quickly to the drain along the lower sealing portion (300).

[0139] In addition, since an insertion guide part (312) is provided on the protrusion (310) located at the top of the lower sealing part (300) and is configured to guide movement in the up-and-down direction through the side guide part (112) of the lower sealing part (300) as the load of sewage is applied by being inserted into the side guide part (112), the opening or closing action of the lower part of the body (100) of the lower sealing part (300) as the load of sewage is applied to the lower sealing part (300) can be performed more stably.

[0140] Referring to FIGS. 13 to 15 and 18, the main guide portion (110) may further include a curved portion (114).

[0141] The above curved portion (114) can be configured to guide the flow of sewage in the flow space of the body (100).

[0142] Specifically, the curved portion (114) may include a first portion (114a) and a second portion (114b).

[0143] The above first part (114a) is connected to the inner surface (inner surface) of the body (100) and may constitute one side of the curved portion (114) when viewed in the circumferential direction of the body (100). However, the first part (114a) may not be connected to the inner surface (inner surface) of the body (100) and may be positioned approximately at the center of the flow space of the body (100).

[0144] The second part (114b) may be connected to the upper portion of a portion (110a) of the main guide part (110) in which the side guide part (112) is formed. In addition, the second part (114b) may be configured to be connected to the first part (114a) in a bent state.

[0145] In this way, since the first part (114a) of the curved portion (114) is connected to the inner surface of the body (100), rotational force is applied to the sewage through the first part (114a) so that the sewage can be discharged into the drain, and therefore, a portion of the flow of the sewage flowing along the inner surface of the body (100) can be more effectively guided toward the drain.

[0146] In addition, since the second part (114b) connected to the first part (114a) is connected to a part of the main guide part (110) located approximately at the center of the flow space of the body (100), the overall flow of sewage can be concentrated approximately toward the center when viewed in the radial direction of the body (100), so that sewage can be discharged toward the drain more quickly.

[0147] In particular, the first part (114a) may include a recessed portion (114a1).

[0148] The above-mentioned recessed portion (114a) can be configured to be recessed in the vertical direction at the bottom of the first portion (114a).

[0149] According to this implementation configuration, when the sewage to which rotational force is applied through the first part (114a) passes through the inlet (114a1), the sewage can be discharged toward the drain with reduced resistance, so that the sewage can be discharged toward the drain more quickly.

[0150] Referring to FIGS. 11, 13, and 15, the main guide portion (110) may be positioned between different first rotation guide portions (120) when viewed in the circumferential direction of the body (100). In addition, the curved portion (114) of the main guide portion (110) may also be positioned between different first rotation guide portions (120) when viewed in the circumferential direction of the body (100).

[0151] In this way, a greater rotational force can be applied to the sewage flowing within the flow space of the body (100) through the plurality of first rotation guide parts (120) formed along the inner surface (inner surface) of the body (100). Accordingly, the sewage can be discharged more quickly toward the drain.

[0152] In addition, since a main guide part (110) is formed between the first rotation guide parts (120) formed along the inner surface (inner surface) of the body (100) to concentrate the overall flow of sewage toward the center, there is an advantage in that more diverse types of rotational force can be applied to the sewage.

[0153] In particular, the first rotation guide portion (120) may be configured to be tilted in one direction when viewed from the circumferential direction of the body (100).

[0154] According to this implementation configuration, since a rotational force can be applied in a certain direction to the sewage flowing within the flow space of the body (100), there is an advantage in that more rapid and stable discharge of sewage is possible.

[0155] Additionally, the second rotation guide portion (220) may include a bending portion (222) and a vertical portion (224).

[0156] The above-mentioned bending portion (222) can be formed by protruding from the upper mounting portion (20) and bending. This bending portion (222) can be formed by protruding from the upper surface of the upper mounting portion (200) and bending while forming a curved surface of a predetermined curvature.

[0157] The above vertical portion (224) may be configured to be connected to the bending portion (222) and extend in the vertical direction. At this time, the vertical portion (224) may be configured to be inclined in one direction when viewed from the circumferential direction of the upper mounting portion (200).

[0158] According to this implementation configuration, since a rotational force can be applied in a certain direction to the sewage flowing into the flow space of the body (10), there is an advantage in that more rapid and stable discharge of sewage is possible.

[0159] In addition, since the sewage to which rotational force is primarily applied through the bending portion (222) on the upper surface of the upper mounting portion (200) can be secondarily applied with a strong rotational force when it hits the vertical portion (224) configured to be inclined in one direction, there is an advantage in that more diverse types of rotational force can be applied to the sewage flowing into the flow space of the body (100).

[0160] Referring to FIGS. 11, 13 and 17, the lower sealing portion (300) may further include a third rotation guide portion (320).

[0161] The third rotation guide part (320) may be configured to guide the flow of sewage flowing in from the body (10). In addition, at least one third rotation guide part (320) may be provided along the lower sealing part (300). As an example, at least one lower sealing part (300) may be provided along the upper surface of the lower sealing part (300).

[0162] According to this implementation configuration, since the rotational force can be additionally applied to the sewage to which the rotational force is applied by the first rotational guide part (120) and the second rotational guide part (220), the sewage can be discharged more quickly toward the drain.

[0163] At this time, as described above, the lower sealing portion (300) can be configured so that the diameter becomes smaller as it goes upward.

[0164] In particular, the third rotation guide part (320) may be configured to be inclined in one direction when viewed from the circumferential direction of the lower sealing part (300). In addition, the third rotation guide part (320) may be configured to have a curvature that increases as it goes toward the upper side of the lower sealing part (300).

[0165] According to this implementation configuration, since a rotational force can be applied in a certain direction to the sewage to be discharged through the flow space of the body (100) into the drain, there is an advantage in that the sewage can be discharged more quickly and stably.

[0166] In addition, since the curvature of the third rotation guide part (320) is configured to be greater on the upper side of the lower sealing part (300) which has a relatively smaller diameter than the lower side, a strong rotational force is generated from the upper side of the lower sealing part (300) for the sewage flowing in from the flow space of the body (100), and then the sewage is induced to flow along the slope of the lower sealing part (300), thereby guiding the sewage to be discharged toward the drain with a greater rotational force generated.

[0167] Meanwhile, the tilting directions of the first rotation guide part (120), the second rotation guide part (220), and the third rotation guide part (320) described above may be the same.

[0168] According to this implementation configuration, in the process of sewage being discharged toward the drain through the upper mounting portion (200), body (100) and lower sealing portion (300), a rotational force can be applied to the sewage in a more consistent direction.

[0169] In addition, referring to FIGS. 13 and 14, the second rotation guide part (220) and the third rotation guide part (320) may be provided in multiple numbers.

[0170] At this time, as in FIGS. 13 and 14, the spacing between the different second rotation guide parts (220) in the circumferential direction of the upper mounting part (200) can be configured to be larger than the spacing between the different first rotation guide parts (120) in the circumferential direction of the body (100).

[0171] In addition, the gap between the different first rotation guide parts (120) in the circumferential direction of the body (100) can be configured to be larger than the gap between the different third rotation guide parts (320) in the circumferential direction of the lower sealing part (300).

[0172] That is, when viewed from the direction in which sewage is discharged toward the drain through the upper mounting portion (200), the body (100), and the lower sealing portion (300), the gap between each of the rotation guide portions (220, 120, 320) may be configured to become smaller as it goes from the upper mounting portion (200) where sewage flows in toward the lower sealing portion (300) where sewage is discharged toward the drain.

[0173] According to this implementation configuration, since it is possible to apply increasingly greater rotational force to the sewage as it moves toward the drain, there is an advantage in that sewage can be discharged more quickly and stably.

[0174] FIG. 19 is a drawing showing a state in which the lower sealing part (300) provided in the sewer trap (30) of FIG. 11 is attached and detached to the body (100). At this time, FIG. 19(a) of FIG. 19 shows a state in which the load of sewage is applied to the lower sealing part (300), and the lower sealing part (300) moves downward along the main guide part (110) to open the lower end of the body (100). In addition, FIG. 19(b) of FIG. 19 shows a state in which the load of sewage applied to the lower sealing part (300) is released, and the lower sealing part (300) moves upward along the main guide part (110) to seal the lower end of the body (100).

[0175] Referring to FIG. 19, the sewer trap (30) may further include a first magnetic force unit (400) and a second magnetic force unit (500).

[0176] The first magnetic force member (400) may be configured to be inserted vertically into the interior of the lower sealing member (300). As an example, the first magnetic force member (400) may be a ring-shaped magnet with a hollow portion formed in the radial center.

[0177] The second magnetic force unit (500) may be provided at the lower end of the main guide unit (110), specifically, at the lower end of a portion (110a) of the main guide unit (110) in which the side guide unit (112) is formed. As an example, the second magnetic force unit (500) may be a cylindrical magnet having a circular cross-section on the horizontal plane (XY). In addition, the second magnetic force unit (500) may have the same polarity as the first magnetic force unit (400).

[0178] In an embodiment of the present invention, the second magnetic force unit (500) may be configured to exert a repulsive force with the first magnetic force unit (400) so that when the load of the sewage flowing through the flow space of the body (100) and applied to the lower sealing unit (300) is released, the lower sealing unit (300) seals the lower part of the body (100).

[0179] That is, in a case where the load of the sewage is applied to the lower sealing portion (300) as in (a) of Fig. 19, the pressing force according to the load of the sewage is greater than the repulsive force acting between the first magnetic portion (400) and the second magnetic portion (500), so that the lower sealing portion (300) can move downward along the main guide portion (110) to open the lower portion of the body (100). In this case, the sewage can be quickly discharged into the drain.

[0180] On the other hand, when the load of sewage applied to the lower sealing portion (300) is released as in (b) of Fig. 19, the lower sealing portion (300) can be moved upward along the main guide portion (110) by the repulsive force acting between the first magnetic portion (400) and the second magnetic portion (500) to seal the lower portion of the body (100). In this case, the foul odor rising from the drain can be blocked by sealing the lower portion of the body (100).

[0181] According to this implementation configuration, when a load of sewage is applied, the lower sealing part (300) is moved to open the lower part of the body (100) so that sewage can be quickly discharged into the drain without a separate complex device or control configuration, and when the load of sewage applied to the lower sealing part (300) is released, the lower sealing part (300) uses magnetic force to seal the lower part of the body (100), so that the foul odor coming up from the drain can be effectively blocked.

[0182] Meanwhile, in the above-described embodiment, a configuration is disclosed in which the lower sealing portion (300) is moved by the repulsive force acting between the first magnetic portion (400) and the second magnetic portion (500), but this is not limited thereto. Instead of the first magnetic portion (400) and the second magnetic portion (500), an elastic member (e.g., a spring, etc.) is provided inside the lower sealing portion (300) to surround the outer surface of the main guide portion (110), so that when the load applied to the lower sealing portion (300) is released, the lower sealing portion (300) seals the lower end of the body (100) by the elastic restoring force of the elastic member.

[0183] Referring to FIGS. 12, 13, 18 and 19, the sewer trap (30) may further include a cap portion (600).

[0184] The cap portion (600) may be configured to accommodate the lower portion (110a) of the main guide portion (110) in which the side guide portion (112) is formed and the second magnetic portion (500). As an example, the cap portion (600) may include, but is not limited to, a material having good elasticity and watertightness (e.g., silicone).

[0185] At this time, when the load of the sewage is applied to the lower sealing part (300) as in (a) of Fig. 19, the maximum movement range of the lower sealing part (300) in the downward direction can be limited when the first magnetic part (400) comes into contact with the cap part (600).

[0186] On the other hand, when the load of the sewage applied to the lower sealing portion (300) is released as in (b) of Fig. 19, the upper end of the protrusion (310) of the lower sealing portion (300) may hit the lower end of the second portion (114b) of the curved portion (114), thereby limiting the maximum upward movement range of the lower sealing portion (300).

[0187] Fig. 20 is a drawing showing a multi-guide device (5) according to the fifth embodiment of the present invention.

[0188] Since the multi-guide device (5) according to the present embodiment is similar to the multi-guide device (1) according to the previous embodiment, duplicate descriptions of components that are substantially the same or similar to those of the previous embodiment will be omitted, and the following will focus on differences from the previous embodiment.

[0189] Referring to Fig. 20, in the multi-guide device (5), the drain trap (30) can be accommodated inside the drain with the upper mounting portion (200) secured to the upper end of the drain when the drain is structured to protrude a predetermined height from the space where the washing machine is installed. In this case, in the present embodiment, the drain can be configured in a cylindrical shape with a predetermined height.

[0190] At this time, the insertion part (16a) of the drain connection cap (16) provided at the bottom of the guide body (10) is inserted into the body (100), so that the bottom of the guide body (10) can be vertically connected to the sewer trap (30) and the drain.

[0191] As described above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below.

[0192] Meanwhile, although terms indicating directions such as up, down, left, right, front, and back are used in the present invention, it is obvious to those skilled in the art that these terms are only for the convenience of explanation and may vary depending on the location of the target object or the location of the observer.
