Specific embodiments

[0023] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific embodiments, structures, features and their effects of the present utility model as follows.

[0024] Embodiment 1:

[0025] A residue crushing structure for a dishwasher provided in this embodiment, as Figures 1-5 shown, includes a water cup 1 and a crushing cutter head 2. The water cup 1 is provided with a water outlet 3 and a water inlet 4 of a drainage pump. The crushing cutter head 2 is located directly in front of the water inlet 4 of the drainage pump, and the crushing cutter head 2 is located directly above the water outlet 3. A driving member 5 for driving the crushing cutter head 2 is provided outside the water cup 1. The output end of the driving member 5 extends into the water cup 1 through the side wall of the water cup 1 and is connected to the crushing cutter head 2. In this embodiment, the driving member 5 adopts a motor.

[0026] After the drainage pump 18 stops working, a part of the water flow will flow back from the water inlet 4 of the drainage pump. The design of the water outlet 3 enables the water flowing back to be drained from the water outlet 3, preventing water accumulation in the water cup 1. The driving member 5 is placed on the side, reducing the overall volume and height at the same time. Compared with the output end of the driving member 5 extending from the bottom of the water cup 1, water easily accumulates at the bottom, and the accumulated water will be in contact with the output end of the driving member 5 for a long time, which is likely to cause leakage through the connection between the output end of the driving member 5 and the water cup 1. Moreover, the crushing cutter head 2 and the driving member 5 occupy the position of the bottom surface of the water cup 1, making it difficult to set the water outlet 3. However, when the output end of the driving member 5 extends into the water cup 1 from the side, the accumulated water at the bottom will not be in contact with the output end of the driving member 5, reducing the leakage risk of the output end of the driving member 5. At the same time, the water outlet 3 can be set on the bottom surface of the water cup 1. When the output end of the driving member 5 extends from the bottom of the water cup, the rotation of the crushing cutter head 2 will drive the water in the water cup 1 to flow in a vortex shape, which is not conducive to the discharge of water. When the output end of the driving member 5 extends laterally, it drives the crushing cutter head 2 to drive the water in the water cup 1 to circulate up and down, which is conducive to the discharge of water.

[0027] To ensure the reliability of the crushing cutter head 2, the crushing cutter head 2 includes a first blade 6 and a second blade 7. The first blade 6 is U-shaped, and the bottom edge of the first blade 6 is connected to the driving member 5. The second blade 7 is U-shaped, and the bottom edge of the second blade 7 is connected to the driving member 5. The bottom edges of the first blade 6 and the second blade 7 are cross-arranged. The first blade 6 is U-shaped with high structural strength. The U-shape has two blades, and compared with a single blade, the crushing efficiency is higher. The second blade 7 is U-shaped with high structural strength. The U-shape has two blades, and compared with a single blade, the crushing efficiency is higher.

[0028] To expand the crushing range, the opening direction of the first blade 6 is opposite to that of the second blade 7, so that the crushing directions of the first blade 6 and the second blade 7 are opposite, expanding the crushing range. The bottom surface of the first blade 6 is attached to the bottom surface of the second blade 7, making the gap between them small, and thus making the gap between the crushing ranges on both sides small.

[0029] To prevent blockage, a filter member 8 is provided on the water outlet 3. A partition plate 9 is provided at the water inlet 4 of the drainage pump. The partition plate 9 is used to block large residues. The partition plate 9 is detachably connected to the water cup 1. The filter member 8 can block residues to prevent them from entering and blocking the pipeline. The partition plate 9 can block large residues at the water inlet 4 of the drainage pump, preventing large residues from directly entering, so that the large residues will be crushed by the crushing cutter head 2 at the water inlet 4 of the drainage pump.

[0030] In this embodiment, an installation groove 19 is provided at the bottom of the groove 11, and the installation groove 19 cooperates with the filter member 8. The filter member 8 is provided with a boss 20 for taking and filter holes 21 for filtering residues.

[0031] To ensure reliable water collection, the water cup 1 includes a water collection groove 10 that is recessed downward; the water outlet 3 is located at the bottom surface of the water collection groove 10 so that the accumulated water in the water collection groove 10 can be drained; the water inlet of the drainage pump 4 is located on the groove wall of the water collection groove 10, and the bottom of the water inlet of the drainage pump 4 is flush with the bottom surface of the water collection groove 10, so that the crushed residue in the water collection groove 10 can flow out from the water inlet of the drainage pump 4 along with the final water flow, preventing the residue from accumulating at the bottom of the groove.

[0032] To facilitate the concentration of the residue, a recessed groove 11 is provided on the groove wall of the water collection groove 10, the water inlet of the drainage pump 4 is located on the groove wall of the recessed groove 11, and the water outlet 3 is located at the bottom surface of the recessed groove 11. At the recessed groove 11 of the water outlet 3, the water flow will flow towards the water outlet 3, and thus will carry the residue into the recessed groove 11, causing the residue in the water collection groove 10 to concentrate towards the recessed groove 11, facilitating the crushing process.

[0033] To improve safety, as Figure 6 shown, a crushing baffle 12 is provided on the recessed groove 11, the crushing baffle 12 is detachably connected to the water cup 1, and a channel 22 is formed between the crushing baffle 12 and the bottom surface of the recessed groove 11; a guiding groove 13 is provided on the groove wall of the recessed groove 11, a guiding block 14 is provided on the crushing baffle 12, and the guiding block 14 is engaged with the guiding groove 13; the water outlet 3 is located directly below the crushing baffle 12. The crushing baffle 12 can prevent the residue from splashing upward during crushing, causing the crushed residue to concentrate in the channel 22, facilitating drainage from the water inlet of the drainage pump 4. At the same time, the crushing baffle 12 can prevent the human hand from directly touching the crushing cutter head 2, improving safety; the cooperation between the guiding block 14 and the guiding groove 13 makes the installation of the crushing baffle 12 convenient.

[0034] To ensure reliable installation of the crushing baffle 12, a clamping block 15 is provided on the crushing baffle 12, a clamping groove 16 is provided on the groove wall of the recessed groove 11, and the clamping block 15 is engaged with the clamping groove 16; a pulling rod 17 is provided at the top of the crushing baffle 12. The cooperation between the clamping block 15 and the clamping groove 16 makes the connection between the crushing baffle 12 and the water cup 1 simple and reliable; the pulling rod 17 can be used to hold when disassembling and installing the crushing baffle 12, facilitating disassembly and assembly.

[0035] To ensure reliable drainage, a drainage pump 18 is provided outside the water cup 1, and the drainage pump 18 is communicated with the water inlet of the drainage pump 4.
