DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This embodiment discloses a zero residual water cup assembly, referring to Figure 1-Figure 6 As shown, it includes a water cup 1, a pump housing 2, a drainage pump 3, a connecting pipe 4, a plug 5 and a driving member 6. The top of the water cup 1 is open and is installed at the bottom 12 of the dishwasher. The water in the inner tank of the dishwasher can fall into the water cup 1, and the water can be discharged through the drainage channel connected to the lower part of the water cup 1.

[0026] Reference Figure 1 , Figure 2 As shown, in this embodiment, the water cup 1, the pump housing 2 and the connecting pipe 4 adopt an integral injection molding structure. The pump housing 2 is fixedly connected to the lower outer side of the water cup 1, and a through hole 11 is opened at the lower part of the water cup 1, so that the inner cavity bottom 12 of the water cup 1 can be connected to the pump housing 2.

[0027] Reference Figure 3 , Figure 4As shown, there is a water stop surface 41 on the inner wall of the connecting pipe 4, and a first opening 42 is provided at the water stop surface 41. The first opening 42 is connected to the pump housing 2, so that the connecting pipe 4 can be connected to the pump housing 2. That is, the water cup 1, the pump housing 2 and the connecting pipe 4 are connected in sequence to form a drainage channel for the water cup 1. An interface 21 is provided at the lower position of the pump housing 2, and the interface 21 and the first opening 42 are connected to each other through a conduit 22. The position of the interface 21 is lower than the through hole 11. The bottom 12 of the water cup 1 also forms an inclined structure, and it is inclined downward toward the through hole 11, so that the water at the bottom 12 of the water cup 1 can be discharged smoothly to the outside. A gradually downward trend can be formed between the water cup 1, the pump housing 2 and the connecting pipe 4, which is conducive to the discharge of water in the water cup 1 and achieves zero residual water.

[0028] Reference Figure 2 , Figure 6 As shown, an opening is formed on one side of the pump housing 2, and a detachable cover plate 31 is installed at the opening. The cover plate 31 and the pump housing 2 can be connected and fixed by a clamping structure or bolts, and the installation can be achieved. In addition, a sealing member is provided at the connection between the cover plate 31 and the pump housing 2 to maintain sealing.

[0029] In this embodiment, the drainage pump 3 is installed on the cover plate 31, the rotating shaft of the drainage pump 3 passes through the cover plate, and the impeller 32 is installed on the rotating shaft. When the drainage pump 3 is installed, its impeller 32 is located in the pump housing 2, and the water in the pump housing 2 can be directed toward the connecting pipe 4 through the rotation of the impeller 32. When the drainage pump 3 is installed, the axis of the impeller 32 is arranged in a roughly horizontal direction, the inner cavity of the pump housing 2 is roughly a cylindrical cavity structure, and the interface 21 at the lower part of the pump housing 2 is arranged roughly along the tangent direction of the impeller 32.

[0030] The connecting pipe 4 is generally in a three-way structure, wherein the two ends of the connecting pipe 4 in the length direction respectively have a first opening 42 and a second opening 44, and a drain port 43 is provided on the side wall of the connecting pipe 4. The drain port 43 is provided on the side wall of the connecting pipe 4, and the outer end of the drain port 43 extends outward, and a drain pipe 7 is installed at the drain port 43 and fixedly connected by a clamp 71. The drain pipe 7 can be a hose, which can bend to lead the water flow out, which is conducive to the layout of the pipeline.

[0031] Reference Figure 4 , Figure 5 As shown, the plug 5 is located in the connecting pipe 4 and can be made of rubber material. The plug 5 is in the connecting pipe 4 and can move along the length direction of the connecting pipe 4 and has a first state and a second state.

[0032] In the first state, the plug 5 abuts against the water stop surface 41, and the first opening 42 can be closed by the surface of the plug 5, thereby disconnecting the first opening 42 and the drain port 43. When the dishwasher is working, the bottom 12 of the water cup 1 can be closed by closing the first opening 42, and water can be stored in the water cup 1; after the dishwasher finishes washing, the first opening 42 can be closed to cut off the water cup 1 from the sewer pipe to prevent odor from flowing back.

[0033] In the second state, the plug 5 is separated from the water stop surface 41 , and the first opening 42 can be opened, so that the first opening 42 and the drain port 43 can be connected to each other, so that the water in the water cup 1 can be drained.

[0034] A second opening 44 is provided at the end of the connecting pipe 4, and the first opening 42 and the second opening 44 are respectively located at both ends of the connecting pipe 4. The second opening 44 serves to install the driving member 6, and a second cover plate 62 is installed at the second opening 44. The driving member 6 is installed on the second cover plate 62 and supported by the second cover plate 62. The second cover plate 62 and the connecting pipe 4 can be connected and fixed by bolts and sealed by a sealing member.

[0035] The power output end 61 of the driving member 6 is a rod-shaped structure, and the power output end 61 passes through the second cover plate 62 and the second opening 44, and can extend into the connecting pipe 4. The power output end 61 and the plug 5 in the connecting pipe 4 are linked to each other, and the plug 5 can be driven to move between the first state and the second state through the telescopic action of the power output end 61, thereby realizing the opening and closing switching of the first opening 42.

[0036] Reference Figure 4 As shown, the plug 5 is made of rubber material and is generally cylindrical in structure. One end of the plug 5 facing the water stop surface 41 is a closed end 51 , and the other end facing away from the water stop surface 41 is an open end 52 . The plug 5 is sleeved outside the power output end 61 .

[0037] A pressing block 611 is fixedly connected to the power output end 61 of the driving member 6, and a convex ring is provided at a position near the closed end 51 inside the plug 5, and a limiting groove is formed between the convex ring and the inner side surface of the closed end 51, and the pressing block 611 can be inserted into the limiting groove, so that a linkage can be formed between the power output end 61 and the closed end 51 of the plug 5. In addition, the pressing block 611 abuts against the inner wall of the closed end 51 of the plug 5. In the first state, the power output end 61 applies pressure to the closed end 51 of the plug 5 through the pressing block 611, and then the outer position of the closed end 51 of the plug 5 abuts against the water stop surface 41, thereby closing the first opening 42 on the water stop surface 41.

[0038] The outer peripheral wall of the plug 5 forms a connected annular fold 53 structure, so that the closed end 51 and the open end 52 of the plug 5 can be elastically adjusted. An annular groove 621 is provided on the side of the second cover plate 62 facing the second opening 44, and the open end 52 of the plug 5 is embedded in the annular groove 621. The outer periphery of the open end 52 and the inner periphery of the annular groove 621 are abutted against each other to achieve sealing, thereby achieving a certain degree of sealing between the end cover 2 and the plug 5, avoiding water leakage at the connection between the power output end 61 and the end cover 2.

[0039] The present embodiment also discloses a dishwasher, including a zero-residual-water cup assembly as in the above embodiment; the dishwasher also includes an inner tank, and the zero-residual-water cup assembly is installed at the bottom 12 of the inner tank, which can achieve drainage of the inner tank and the water cup 1 of the dishwasher, avoiding water accumulation in the dishwasher.
