Description

Connector and dishwasher containing same

The present invention relates to a connector and a dishwasher including the same, and more particularly, to a connector connected to a sink drain pipe and a dishwasher including the same.

A dishwasher uses water to wash dishes placed inside and drains the used water. A dishwasher can be built-in and installed in the kitchen, or it can be installed separately in the kitchen. In this case, the water drained from the dishwasher is drained through a drain pipe connected to the sink.

The dishwasher drain hose can be connected to the drain pipe installed in the sink using a separate connector. The dishwasher drain pipe can be installed at the bottom of the S-trap of the sink considering the space of the sink drain pipe. As shown in Fig. 9, the dishwasher drain hose connected to the sink drain pipe using a conventional connector can cause noise when the water from the dishwasher is drained.

As water drains down the S-trap, water that has accumulated in the S-trap can flow along with it, which can cause noise. Also, if the drain pipe is clogged downstream of the S-trap, water from the dishwasher can flow back toward the S-trap and then drain again, causing noise.

Publication number KR 10-2018-0006099 A discloses a connection structure between a dishwasher and a sink drain pipe, but does not disclose a connection structure reflecting an S-trap structure.

The problem to be solved by the present invention is to provide a connector and a dishwasher including the connector that minimizes noise generated during the drainage process even when water drained from the dishwasher is drained through the drain pipe of the sink.

Another object of the present invention is to provide a connector that can be connected regardless of whether it is upstream or downstream of an S-trap.

Another object of the present invention is to provide a connector that can be connected regardless of the structure or arrangement of the sink drain pipe.

Another object of the present invention is to provide a connector that can easily mount a separate drain hose for a water purifier or the like and prevent foreign substances from entering the drain hose.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, a connector according to an embodiment of the present invention includes a main pipe having a main channel extending vertically, a first inlet formed at an upper end of the main channel, and an outlet formed at a lower end of the main channel, a first connecting pipe connected to one side of a peripheral wall of the main pipe and forming a first connecting pipe channel therein, and a second connecting pipe connected to the other side of the peripheral wall of the main pipe, wherein a lower end of a portion where the second connecting pipe is connected to the main pipe is disposed vertically lower than a portion where the first connecting pipe is connected to the main pipe, and an upper end of an end of the second connecting pipe is disposed vertically higher than an upper end of the first connecting pipe. That is, the first connecting pipe has a structure in which an internal space is separately formed or an additional drain pipe is connected in another direction, and the second pipe has a structure in which it is disposed to be inclined downward.

The first connecting pipe and the second connecting pipe are arranged in opposite directions on the peripheral wall of the main pipe, and the virtual flow direction in which the second connecting pipe extends is located lower than the position at which the first connecting pipe is connected to the main pipe, so that water drained through the second connecting pipe is drained to the lower side of the space formed by the first connecting pipe.

The upper end of the second connecting pipe is positioned at a certain distance from the upper end of the main pipe, so that connection between the second connecting pipe and the drain pipe is possible even if the connector is positioned adjacent to the sink.

The upper end of the second connecting pipe is spaced apart from the upper end of the main pipe by more than half the size of the inner diameter of the main pipe, so that a space for connecting the second connecting pipe can be secured.

The angle formed between the first connecting pipe and the main pipe is formed larger than the angle formed between the second connecting pipe and the main pipe.

The inner diameter of the first connecting pipe is formed to be larger than the inner diameter of the second connecting pipe, and a first connecting pipe passage is formed inside the first connecting pipe, so that the first connecting pipe passage can secure a space of a certain size.

The above main pipe includes an upper pipe connected to an upstream drain pipe arranged on the upper side, a lower pipe connected to a downstream drain pipe arranged on the lower side, and a middle pipe connecting the upper pipe and the lower pipe.

The first connecting pipe is arranged on one side of the circumference of the above middle pipe, and the second connecting pipe is arranged on the other side of the circumference of the above middle pipe.

The upper pipe includes a first connecting part to which a connecting member arranged to be connected to the upstream drain pipe is connected, and the first connecting pipe includes a second connecting part to which another connecting member or a blocking member for closing the first connecting pipe is connected, so that a separate connecting member can be connected to the upper pipe and/or the first connecting pipe.

The length of the first connecting part from the point where the first connecting pipe and the main pipe are connected is formed shorter than the length of the second connecting part from the point where the first connecting pipe and the main pipe are connected, so that a space for forming the first connecting pipe can be secured.

The first fastening part includes a first fixing projection protruding from the circumferential surface to limit downward movement of the fastening member, and a first separation projection positioned above and spaced apart from the first fixing projection and protruding from the circumferential surface, and the upper end of the second connecting pipe is positioned lower than the first separation projection, so that the drain pipe can be freely connected to the second connecting pipe.

A connecting hole is formed on one side of the circumference of the above main pipe to which a separate drain hose is connected.

The above connecting hole is formed at a higher position than the portion where the second connecting pipe is connected to the main pipe, thereby preventing water drained from the drain pipe from flowing into the connecting hole.

Inside the above main pipe, an upper cover protruding inward from the inner surface of the main pipe to cover the upper side of the connecting hole can be included, thereby preventing water drained to the connector from flowing into the connecting hole.

The above upper cover is formed in a semi-circular shape on the upper side of the connecting hole and can cover the upper side of the communicating hole.

A stopper is arranged on the inner surface of the main pipe at a portion where the connecting hole is formed, and the stopper is arranged so as to cross the connecting hole on the inner surface of the main pipe.

The dishwasher of the present invention comprises a main body for washing dishes using water, a drain pipe for draining water used in the main body, and a connector for connecting the drain pipe to a sink drain pipe connected to a sink, wherein the connector comprises a main pipe having a main channel extending vertically, a first inlet formed at an upper end of the main channel and a discharge port formed at a lower end of the main channel, a first connecting pipe connected to one side of a peripheral wall of the main pipe and forming a first connecting pipe channel therein, and a second connecting pipe connected to the other side of the peripheral wall of the main pipe and connected to the main body, wherein the upper end of the second connecting pipe is disposed at a predetermined distance downward from the upper end of the main pipe. Accordingly, a drain pipe can also be connected to the second connecting pipe in a connector disposed adjacent to a sink.

The above main pipe includes an upper pipe connected to an upstream drain pipe arranged on the side, a lower pipe connected to a downstream drain pipe arranged on the lower side, and a middle pipe connecting the upper pipe and the lower pipe, and the lower pipe is connected to the upper side of an S-trap connected to the drain pipe.

The above upper pipe is connected to the drain pipe or the lower part of the sink, and the upper end of the second connecting pipe is spaced apart from the upper end of the main pipe by more than half the size of the inner diameter of the main pipe, so that the drain pipe can be freely connected to the second connecting pipe.

The above upper pipe is connected to the lower side of the S-trap connected to the drain pipe, the inner diameter of the first connecting pipe is formed larger than the inner diameter of the second connecting pipe, and a first connecting pipe passage is formed inside the first connecting pipe.

Specific details of other embodiments are included in the detailed description and drawings.

According to the connector of the present invention and the dishwasher including the same, one or more of the following effects are achieved.

First, the connector of the present invention has a structure in which a second connecting pipe that can be connected to a dishwasher extends downwardly from the first connecting pipe. The first connecting pipe can be arranged above the second connecting pipe to form a separate space or communicate with the airflow hole. Therefore, there is an advantage in that noise caused by water draining through the second connecting pipe can be minimized.

Second, the upper part of the second connecting pipe is positioned lower than the upper part of the main pipe. Therefore, even if the connector is positioned on the upper part of the S-trap, the dishwasher drain pipe can be easily connected to the second connecting pipe. This also has the advantage of increasing the degree of freedom in the arrangement of the connector.

Third, since separate fastening parts are formed for each of the main pipe and the first connecting pipe, there is also an advantage in that the sink drain pipe can be connected to the main pipe or the first connecting pipe depending on the sink drain pipe structure.

Fourth, a connection hole is formed on one side of the connector to connect to a drain hose of a water purifier, etc., and an upper cover and a stopper are formed around the connection hole. The insertion degree of the drain hose can be adjusted through the stopper to increase the ease of installation. In addition, the upper cover can prevent foreign substances from entering the drain hose.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

One end of the connecting pipe (62) may be arranged on the outer circumference of the first separating projection (20). Screw threads may not be formed on one end of the connecting pipe (62) arranged on the outer circumference of the first separating projection (20).

The holder (64) is arranged between the first fixed projection (18) and the first spaced projection (20). The diameter (64D) of the inner surface of the holder (64) may be formed smaller than the diameter (18D) of the outer surface of the first fixed projection (18) or the diameter (20D) of the outer surface of the first spaced projection (20). The holder (64) may have a structure extending circumferentially from one side of the connecting tube (62). A plurality of holders (64) may be arranged spaced apart from each other in the circumferential direction. The plurality of holders (64) may have an overall ring-shaped structure.

The lower pipe (22) may be positioned at a position spaced downward from the upper pipe (14). The lower pipe (22) may be formed to have a larger diameter than the middle pipe (24) or the upper pipe (14). A screw thread may be formed on the outer surface of the lower pipe (22) to connect to the downstream drain pipe (2b).

The middle pipe (24) can connect the upper pipe (14) and the lower pipe (22). The length (24L) of the middle pipe (24) extending in the vertical direction can be formed to be longer than the length (14L) of the upper pipe (14) or the length (22L) of the lower pipe (22).

A first connecting pipe (40) may be arranged on one side of the circumference of the middle pipe (24). A second connecting pipe (50) may be arranged on another side of the circumference of the middle pipe (24). A connecting hole (26) is formed on another side of the circumference of the middle pipe (24).

The first connecting pipe (40) and the second connecting pipe (50) are arranged to extend in different directions with respect to the middle pipe (24). The first connecting pipe (40) and the second connecting pipe (50) are arranged to extend in opposite directions with respect to the middle pipe (24).

The first connecting pipe (40) is connected to the middle pipe (24) from above the second connecting pipe (50). The first connecting pipe (40) is connected to the middle pipe (24) at a position closer to the upper pipe (14) than the second connecting pipe (50). The first connecting pipe (40) can be arranged perpendicular to the middle pipe (24). That is, referring to FIG. 5, the first connecting pipe path (40) formed by the first connecting pipe (40) can be formed in a direction perpendicular to the main path (12a) formed by the main pipe (12).

The second connecting pipe (50) is connected to the middle pipe (24) at a lower position than the first connecting pipe (40). The second connecting pipe (50) is arranged to be inclined downward. The virtual flow direction in which the second connecting pipe (50) extends can be formed lower than the position at which the first connecting pipe (40) is connected to the middle pipe (24).

In the middle pipe (24), a connecting hole (26) is formed to which a drain hose (not shown) is connected. Here, the drain hose (5) can send water drained from a separate device to the connector (10). For example, the drain hose (5) can be structured to be connected to a water purifier installed or placed in a sink.

Inside the middle tube (24), an upper cover (28) is arranged above the connecting hole (26). The upper cover (28) may have a structure that protrudes inward from the inner surface of the middle tube (24). The upper cover (28) may be formed in a semi-circular shape above the connecting hole (26). The upper cover (28) may be arranged to be spaced upward by a certain distance from the connecting hole (26).

The first connecting pipe (40) has a structure extending from the circumference of the main pipe (12). The first connecting pipe (40) may include a second connecting part (42) to which a separate connecting member (60) is connected.

The second fastening part (42) may have the same shape as the first fastening part (16) of the main pipe (12). Accordingly, the drain pipe connected to the sink may be selectively connected to either the first fastening part (16) or the second fastening part (42) depending on the location. In addition, the first fastening part (16) may be connected to the drain pipe of the sink, and the second fastening part (42) may be connected to the additional pipe (4) of the sink. The additional pipe (4) may be a pipe connected to an overflow hole formed in the sink so that water does not exceed a certain level in the sink.

A fastening member (60) having the same configuration as the first fastening part (16) can also be mounted on the second fastening part (42).

The second fastening part (42) may include a second fixing projection (44) protruding from the circumferential surface of the first connecting pipe (40) to limit the unilateral movement of the holder (64) of the fastening member (60), and a second spacing projection (46) protruding from the circumferential surface of the first connecting pipe (40) and spaced apart from the first fixing projection (18) in the direction of the end of the first connecting pipe (40).

The height (44h) at which the second fixed projection (44) protrudes from the circumferential surface of the first connecting pipe (40) may be formed to be greater than the height (46h) at which the second spacer projection (46) protrudes from the circumferential surface of the first connecting pipe (40). A holder (64) of a fastening member (60) may be arranged between the second fixed projection (44) and the second spacer projection (46).

<Layout relationship of connector configuration>

Hereinafter, with reference to FIG. 5 and FIG. 10, the relationship between the arrangement of the upper pipe (14), the first connecting pipe (40), and the second connecting pipe (50) of the main pipe (12) will be additionally explained.

The length (L1) of the first connecting part (16) from the point (P) where the first connecting pipe (40) and the main pipe (12) are connected can be formed shorter than the length (L2) of the second connecting part (42) from the point (P) where the first connecting pipe (40) and the main pipe (12) are connected.

The first connecting pipe (40) can be arranged vertically to the main pipe (12). The first connecting pipe (40) is arranged in the opposite direction to the second connecting pipe (50). The part where the first connecting pipe (40) is connected to the main pipe (12) can be arranged higher than the part where the second connecting pipe (50) is connected to the main pipe (12).

At the part where the first connecting pipe (40) is connected to the main pipe (12), the upper end (41a) of the first connecting pipe (40) is formed higher than the upper end (50a) of the second connecting pipe (50) at the part where the second connecting pipe (50) is connected to the main pipe (12). At the end of the first connecting pipe (40), the upper end (41b) of the first connecting pipe (40) can be formed lower than the upper end (51a) of the second connecting pipe (50) at the end of the second connecting pipe (50).

The inner diameter (40D) of the first connecting pipe (40) may be formed to be larger than the inner diameter (50D) of the second connecting pipe (50). A virtual extension pipe extending in the direction in which the first connecting pipe (40) is connected to the main pipe (12) may be formed to pass through the second connecting pipe (50). However, the virtual extension pipe extending in the direction in which the second connecting pipe (50) is connected to the main pipe (12) may have a structure extending downwardly of the first connecting pipe (40). A virtual line extending from the upper end of the second connecting pipe (50) through the main pipe (12) may be arranged to be spaced downwardly from the first connecting pipe (40).

The second connecting pipe (50) may have an upper end (50a) of the portion connected to the main pipe (12) positioned lower than the upper end (51a) of the end (51) of the second connecting pipe (50). The second connecting pipe (50) may have a structure that extends upwards as it gets farther away from the main pipe (12).

The upper end (51a) of the end (51) of the second connecting pipe (50) may be positioned lower than the upper end of the main pipe (12). The upper end (51a) of the end (51) of the second connecting pipe (50) may be positioned spaced downward from the upper end of the main pipe (12). The upper end (51a) of the end (51) of the second connecting pipe (50) may be positioned lower than the first spacer (20). The upper end (51a) of the end (51) of the second connecting pipe (50) may be positioned between the first fixing protrusion (18) and the first spacer protrusion (20).

The angle (θ2) formed between the first connecting pipe (40) and the main pipe (12) can be formed to be larger than the angle (θ1) formed between the second connecting pipe (50) and the main pipe (12).

The connecting hole (26) may be positioned lower than the upper pipe (14). The connecting hole (26) may be formed at a higher position than the portion where the second connecting pipe (50) is connected to the main pipe (12). The connecting hole (26) may be formed at the same position as the position formed by the upper end of the first connecting pipe (40).

A connecting hole (26) can be formed in the main pipe (12) between the first connecting pipe (40) and the second connecting pipe (50).

Referring to FIGS. 4 and 5, the connecting hole (26) is positioned above the joint (48) of the main pipe (12) and the first connecting pipe (40). The first joint (48) of the main pipe (12) and the first connecting pipe (40) may be formed along the circumference of the main pipe (12). Here, the connecting portion of the first joint (48) of the main pipe (12) and the first connecting pipe (40) may mean a portion where the inner or outer surfaces of the pipes are morphologically joined.

The connecting hole (26) is positioned above the second joint (58) of the main pipe (12) and the second connecting pipe (50). The second joint (58) of the main pipe (12) and the second connecting pipe (50) can be formed along the circumference of the main pipe (12).

Accordingly, since the portion where the connecting hole (26) is formed is not formed in the portion where the first joint (48) or the second joint (58) is formed, the productivity of the connector (10) can be increased. In the portion where the first joint (48) or the second joint (58) is formed, a complex shape can be formed, so that the connecting hole (26) can be arranged by avoiding such an area.

Referring to Fig. 10, the second connecting pipe (50) and the first connecting pipe (40) may be arranged in opposite directions with respect to the main pipe (12). In addition, the connecting hole (26) may be formed on one side of the main pipe (26) between the first connecting pipe (40) and the second connecting pipe (50). The connecting hole (26) may be arranged to be perpendicular to or inclined with respect to each of the first connecting pipe (40) and the second connecting pipe (50) with respect to the main pipe (12).

However, the arrangement of the first connecting pipe (40), the second connecting pipe (50), and the connecting hole (26) arranged or formed around the main pipe (12) may be changed. Referring to FIG. 11, the connecting hole (26) may be arranged in the opposite direction of the first connecting pipe (40). In this case, the second connecting pipe (50) may be arranged on the circumferential surface of the main pipe (12) between the connecting hole (26) and the first connecting pipe (40). That is, the connecting hole (26) and the first connecting pipe (40) may be arranged parallel to each other, and the second connecting pipe (50) may be arranged to be perpendicular to or at an angle to each of the first connecting pipe (40) and the connecting hole (26) with respect to the main pipe (12).

Also, referring to Fig. 12, the connecting hole (26) may be arranged in the opposite direction of the second connecting pipe (50). In this case, the first connecting pipe (40) may be arranged on the circumferential surface of the main pipe (12) between the connecting hole (26) and the second connecting pipe (50).

The connecting hole (26) and the second connecting pipe (50) are arranged parallel to each other, and the first connecting pipe (40) can be arranged perpendicular to or at an angle to the second connecting pipe (50) and the connecting hole (26) with respect to the main pipe (12).

In a structure such as Fig. 12, the connecting hole (26) may be arranged above a virtual line extending from the second connecting pipe (50). In addition, in a structure such as Fig. 12, the upper cover (28) arranged around the connecting hole (26) may be formed in a shape such as the structure illustrated in Fig. 6b. The upper cover (28) may be arranged to cover the upper side of the connecting hole ((26)) and the direction in which the first connecting hole (40) is arranged.

<Connector placement>

Below, the arrangement of the connector of the present invention is described with reference to FIG. 1 and FIG. 7.

The connector (10) can be placed on the upper or lower side of the S-trap (6).

As shown in Fig. 1, a connector (10) may be placed on the upper side of the S-trap (6). In this case, the connector (10) may be connected to the upper pipe (14) of the sink with the upstream drain pipe (2a), and the lower pipe (22) may be connected to the S-trap (6). In addition, a downstream drain pipe (2b) may be placed on the lower side of the S-trap (6). The first connecting pipe (40) of the connector (10) may be connected to the additional pipe (4). Unlike the drawing, the first connecting pipe (40) may not be connected to a separate additional pipe (4) and may be blocked.

In addition, if the space for the upstream drain pipe (2a) is not secured, the connector (10) may be directly connected to the lower side of the sink (1). In this case, the connector (10) of the present invention may be arranged so that the upper end (51a) of the second connecting pipe (50) is spaced downward by a certain distance from the upper end of the upper pipe (14), thereby enabling the connection of the drain pipe (3) and the second connecting pipe (50).

As shown in Fig. 7, a connector (10) may be placed on the lower side of the S-trap (6). In this case, the connector (10) may be connected to the upper pipe (14) with the S-trap (6) and the lower pipe (22) with the downstream drain pipe (2b). It is also possible to additionally place a separate drain pipe between the S-trap (6) and the upper pipe (14).

In addition, an upstream drain pipe (2a) or a sink (1) may be placed above the S trap (6). The first connecting pipe (40) of the connector (10) may be blocked without being connected to a separate additional pipe (4). Even when the first connecting pipe (40) is blocked, the internal space of the first connecting pipe (40) may be formed. That is, the first connecting pipe passage (40a) may form a certain space.

Accordingly, the force of the water drained through the second connecting pipe (50) on the flow of accumulated water in the S-trap (6) can be reduced. In addition, even if a portion of the water drained through the second connecting pipe (50) flows backwards when a portion of the downstream drain pipe (2b) is blocked, the force applied to the water inside the S-trap (6) can be reduced by flowing into the first connecting pipe passage (40a). In other words, the space inside the first connecting pipe passage (40a) can function as a buffer chamber.

Referring to Fig. 9, it can be confirmed that noise generated during drainage is reduced when the connector (10) of the present invention is connected (B, B’, C, C’) compared to when the conventional connector as in Fig. 8 is connected (A, A’). Points (A, B, C) are the results of measuring noise when the rotation speed of the drain pump (not shown) of the dishwasher is increased compared to the rotation speed at (A’, B’, C’).

In addition, it can be confirmed that noise is reduced when the connector (10) is placed on the upper side of the S-trap (6) (C, C’) than when it is placed on the lower side of the S-trap (6) (B, B’).

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Furthermore, such modifications should not be understood individually from the technical idea or prospect of the present invention.
