[0029] Reference Figures 1 to 4 A drainage structure for a dishwasher according to an embodiment of the present invention includes a main pipe 100, an auxiliary pipe 200, and a dredging piece 300.

[0030] The main pipe 100 connects the dishwasher and the drain outlet for drainage. The main pipe 100 has a corner 101 . The corner 101 is easily clogged, so a dredging port is opened on the corner 101 .

[0031] The auxiliary pipe 200 is provided at the corner 101 of the main pipe 100, and its two ends are connected to the two ends of the corner 101 respectively. Figure 1 The left end of the auxiliary pipe 200 is connected to the upper end of the corner 101, and the right end of the auxiliary pipe 200 is connected to the lower end of the corner 101. When the corner 101 is blocked, the main pipe 100 cannot flow. The water flow at the corner 101 can enter the auxiliary conduit, cross the corner 101 through the auxiliary conduit, and return to the main conduit to discharge the water. At this time, the auxiliary conduit plays the role of replacing the corner 101 part to divert and drain water.

[0032] The diameter of the auxiliary pipe 200 is smaller than that of the main pipe 100, so that the occurrence of blockage can be detected by the change in drainage speed. However, the drainage capacity of the auxiliary pipe 200 is limited and it cannot be used to drain water all the time. Therefore, the present invention also provides a clearing piece 300 that can easily clear the blockage.

[0033] The clearing piece 300 is passed through the auxiliary pipe 200 , and one end of the clearing piece 300 extends into the corner 101 through the clearing port, and can move along the clearing port to loosen the blockage at the corner 101 . During the movement, the clearing piece 300 will not separate from the clearing port.

[0034] When using this embodiment, after discovering blockage at the corner 101 of the main pipe 100, that is, after discovering that drainage has slowed down, move the clearing piece 300 to loosen the blockage at the corner 101. With the action of water flow, the blockage can be washed away and the corner 101 can be cleared. If the loosening effect is very small, other methods can be used to deal with it.

[0035] In some embodiments of the present invention, the dredging port is provided with a first connecting portion 110 extending outward, and a dredging pipe 210 is provided on the auxiliary pipe 200. Specifically, referring to Figure 1 The dredging pipe 210 is located on the side of the auxiliary pipe 200 facing the main pipe 100 (ie, the lower side), and the first connecting portion 110 is located on the side of the corner 101 facing the auxiliary pipe 200 (ie, the upper side).

[0036] The dredging pipe 210 is open at both ends, and the lower end is connected to the first connecting portion 110. The dredging member 300 is disposed within the dredging pipe 210 and can move along the dredging pipe 210. Specifically, the outer diameter of the dredging pipe 210 is the same as the inner diameter of the first connecting portion 110, and the connection is detachable. After the two are connected, they can be fixed by a locking ring or other fastening structure. A sealing gasket can also be provided on the inner wall of the first connecting portion 110.

[0037] Reference Figures 2 to 3 In a further embodiment of the present invention, the dredging member 300 is hollow and sealed at both ends. The portion intersecting the auxiliary pipe 200 is hollowed out to allow water in the auxiliary pipe 200 to flow through and be discharged. The length of the hollow portion is related to the travel range of the dredging member 300. The dredging member 300 will not extend the hollow portion from the dredging pipe 210 during movement. In addition, the dredging member 300 is sealed at both ends. Therefore, when the corner 101 is loosened, water in the auxiliary pipe 200 will not leak out of the dredging member 300, which can also prevent odor from escaping.

[0038] Reference Figure 4 In a further embodiment of the present invention, a plurality of dredging rods 310 are connected to the end surface of the dredging member 300 extending into the corner 101. As the dredging member 300 moves, the dredging rods 310 are used to loosen the blockage in the corner 101. Specifically, the dredging rods 310 have tapered portions 311 for insertion into the gaps in the blockage. Furthermore, to prevent the tapered portions 311 of the dredging rods 310 from colliding with the inner wall of the main pipe 100 and causing damage, the tips of the tapered portions 311 may be rounded or ground flat.

[0039] In addition to the loosening effect of the dredging rod 310, the water flowing into the dredging member 300 can also be utilized. Figure 4 In some embodiments of the present invention, a plurality of dredging holes 320 are provided on the end face of the dredging piece 300 extending into the corner 101. Part of the water flow in the auxiliary pipe 200 enters the dredging piece 300 and is ejected from the dredging holes 320 to form a water flow with impact force, which can cooperate with the dredging rod 310 to gradually disperse the blockage.

[0040] In a further embodiment of the present invention, the end surface of the dredging member 300 that extends into the corner 101 (i.e., the lower end) protrudes outward to provide a number of dredging portions 321, and the dredging holes 320 are provided through the dredging portions 321; in the direction of water flow, the dredging holes 320 are larger at the top and smaller at the bottom and are in the shape of a cone. This arrangement can make the water flow have greater impact force when it is ejected from the dredging holes 320.

[0041] Reference Figure 2 In some embodiments of the present invention, an auxiliary pipe 200 extends from one end (ie, the upper end) of the dredging pipe 210 away from the corner 101 to prevent water from overflowing from the dredging pipe 210 .

[0042] Reference Figures 2 to 3 In a further embodiment of the present invention, an operating portion 330 is provided at the end of the clearing piece 300 away from the corner 101 for grasping, and the clearing piece 300 can be moved by pulling the operating portion 330; in addition, the operating portion 330 cannot enter the clearing pipe 210, and it can also avoid the situation where the clearing piece 300 falls into the main pipe 100 and cannot be pulled out.

[0043] A spring 331 is connected between the operating portion 330 and the end of the dredging pipe 210 to limit the position of the dredging member 300 in the absence of external force, preventing the dredging member 300 from excessively extending into the corner 101 and affecting the drainage of the main pipe 100. It is conceivable that, in the absence of blockage, the portion of the dredging member 300 extending into the corner 101 should not be too long or even need not be extended at all. With the provision of the spring 331, the spring 331 provides support and limitation for the dredging member 300, maintaining the dredging member 300 (dredging rod 310) in a suitable position relative to the corner 101, preventing excessive extension into the corner 101 that would otherwise cause debris to cling and accumulate.

[0044] Reference Figure 3 In a further embodiment of the present invention, the main pipe 100 is further provided with a second connecting portion 120 and a third connecting portion 130, respectively disposed at the upper and lower ends of the corner 101, for connecting the two ends of the auxiliary pipe 200 to achieve communication between the main pipe 100 and the auxiliary pipe 200. The first connecting portion 110, the second connecting portion 120, and the third connecting portion 130 can all be made of elastic material. By providing the first connecting portion 110, the second connecting portion 120, and the third connecting portion 130, a detachable connection between the auxiliary pipe 200 and the main pipe 100 can be achieved, facilitating replacement of the auxiliary pipe 200.

[0045] Specifically, the outer diameter of the auxiliary pipe 200 is the same as the inner diameter of the second connecting part 120 and the third connecting part 130, and is detachably connected. After the corresponding connection, it can be fixed by a locking ring or other fastening structure, and a sealing gasket can also be set on the inner wall of the second connecting part 120 and the third connecting part 130.

[0046] In some embodiments of the present invention, filters (not shown in the figure) are provided at both ends of the auxiliary pipe 200 to prevent some residues in the main pipe 100 from entering the auxiliary pipe 200 with the water flow and causing blockage of the auxiliary pipe 200; the filter is also detachable and can be cleaned and replaced in time.
