Description

Technical Field

[0001] This utility model relates to the field of dishwasher drainage technology, specifically to drainage components and dishwashers. Background Technology

[0002] Traditional dishwashers typically place the drain pump below the sink drain outlet to facilitate drainage. However, in actual operation, food scraps from dishes enter the drainage system with the water flow. These scraps easily accumulate in the drain pipes, causing blockages and affecting the dishwasher's normal operation. To address this, a filter is usually installed at the drain outlet at the bottom of the sink to intercept food scraps in the water flow and prevent them from entering the subsequent pipes. However, the intercepted scraps continue to accumulate on the filter surface, reducing the effective surface area for water flow. If the filter is not cleaned in time, it increases the resistance to water flow into the drain pipes, reduces the drainage speed, and ultimately triggers a drain malfunction alarm. Utility Model Content

[0003] In view of this, the present invention provides a drainage component and a dishwasher to solve the problems that food residue can easily clog the pipes, and that if the filter screen is not cleaned in time, the resistance of water flow into the drainage pipe will increase, the drainage speed will decrease, and eventually trigger the drainage function failure alarm.

[0004] In a first aspect, this utility model provides a drainage assembly, including a water cup and a drainage pump. The water cup includes a water cup body with a water passage cavity and a drainage interface disposed on the side of the water cup body. The bottom wall of the water passage cavity is provided with a first drainage outlet, and the drainage interface has a drainage channel communicating with the first drainage outlet. The drainage pump includes a drainage pump body, an output shaft, and a cutting blade. The drainage pump body is installed in the drainage interface. The output shaft is arranged in a horizontal direction, and the end of the output shaft away from the drainage pump body extends to the intersection of the drainage channel and the first drainage outlet. The cutting blade is fixed on the end of the output shaft.

[0005] Beneficial effects: The bottom wall of the water passage chamber has a first drain outlet, and the drain interface contains a drain channel communicating with this first drain outlet. When food residue flows with the water through the first drain outlet into the drain channel, it naturally settles and accumulates at the bottom of the drain channel under gravity. When the drain pump starts, its horizontally positioned output shaft drives the cutting blades to rotate, effectively cutting and pulverizing the food residue flowing through this area. The pulverized fine fragments are then carried by the water flow and discharged into the external drain pipe through the drain channel. This ensures that the food residue is fully pulverized before discharge, effectively solving the problem of blockage in the external drain pipe. Furthermore, the horizontal output shaft design allows the rotation plane of the cutting blades to extend vertically. Compared to a vertical output shaft structure, this design effectively avoids food residue settling and accumulating, which can compress the cutting blades and ensure smooth blade rotation. It requires less driving force, reducing energy consumption and saving electricity. Furthermore, the rotating blades disturb the relatively still water layer and deposited food residue at the bottom of the channel, lifting and carrying them into the water flow. This helps prevent the formation of a difficult-to-remove silt layer at the bottom of the drainage channel, further ensuring unobstructed drainage. Moreover, compared to the traditional method of installing a filter screen at the bottom of the sink, it reduces the frequency of filter cleaning, ensuring smooth drainage, reducing the risk of user complaints due to poor drainage, and improving the user experience.

[0006] In one alternative embodiment, the drain pump further includes drain fan blades fixed to the output shaft and located between the drain pump body and the cutting blades.

[0007] Beneficial effects: The rotation of the drainage fan blades fixed on the output shaft generates strong drainage power, which directly drives the water flow to carry the cut residue particles and discharge them efficiently from the drainage channel.

[0008] In one optional embodiment, a second drain outlet is provided on the peripheral wall of the drain interface, and the drain fan blade is located directly opposite the second drain outlet.

[0009] Beneficial effects: Because the drainage fan blades are positioned correspondingly to the second drain outlet, the axial water flow generated by the rotation of the drainage fan blades is directly aligned with the drain outlet direction. This eliminates ineffective turbulence in the drainage channel, preventing the disorderly circulation of debris and particles. Furthermore, it allows the water flow to directly carry the cut debris and particles, efficiently discharging them along the shortest path. This not only improves drainage efficiency but also avoids the risk of particle deposition or secondary accumulation due to flow direction deviation, ensuring unobstructed drainage.

[0010] In one optional embodiment, the drainage channel includes a first channel and a second channel; the top is connected to the main body of the water cup; the cutting blade is disposed in the first channel; the second channel is coaxially disposed with the first channel, and its two ends are respectively connected to the first channel and the drainage pump body, the second drain outlet is disposed on the side wall of the second channel, and the drainage fan blade is located in the second channel.

[0011] Beneficial effects: Since the top of the first channel is connected to the main body of the water cup, and the cutting blade is located inside the first channel, water containing residue can enter the first channel and the residue can be cut by the cutting blade. The two ends of the second channel are connected to the first channel and the drain pump body, respectively. The drain fan blade is located in the second channel, and the second drain outlet is located on the side wall of the second channel. The cut residue particles can enter the second channel with the power generated by the drain fan blade and be smoothly discharged from the second drain outlet with the water flow. This achieves an orderly connection between residue treatment and drainage, avoids the accumulation of residue in the drainage channel, and ensures the smooth flow of the drainage system.

[0012] In one alternative implementation, the inner diameter of the first channel is smaller than the inner diameter of the second channel.

[0013] Beneficial effects: Since the first channel and the second channel are coaxially arranged, and the inner diameter of the first channel is smaller than that of the second channel, it ensures that the residue particles after cutting can flow smoothly and efficiently from the first channel into the second channel with the water flow, effectively preventing the residue from accumulating at the bottom of the first channel and avoiding obstruction of the flow of residue due to unreasonable structure.

[0014] In one alternative implementation, the drain pump body is snapped into the drain interface.

[0015] Beneficial effects: By snapping the drain pump body to the drain interface, a quick and secure connection and separation between the drain pump body and the drain interface is achieved, improving assembly and maintenance efficiency. Installation or removal between the drain pump and the drain interface can be completed without additional tools, making the operation convenient and time-saving.

[0016] In one optional embodiment, the drain pump body is provided with at least two slots, which are circumferentially spaced around the drain pump body, and the drain interface is provided with at least two buckles, which are engaged with the slots one by one.

[0017] Beneficial effects: By setting at least two slots and at least two buckles to engage one-to-one, the stability of the connection between the drainage pump and the drainage interface is ensured. Furthermore, the at least two slots are circumferentially spaced around the drainage pump body, ensuring the uniformity of the connection force, reducing the risk of failure due to loose connection, and guaranteeing the reliability and stability of the drainage pump during operation.

[0018] In one alternative embodiment, the cutting blade is detachably connected to the output shaft.

[0019] Beneficial effects: Since the cutting blade is detachably connected to the output shaft, when the cutting blade is worn or damaged, the cutting blade can be replaced quickly and independently without replacing or disassembling the entire drain pump, reducing the cost and time of cutting blade replacement.

[0020] In one optional embodiment, the cutting blade is provided with a connecting hole; the output shaft includes a first section and a second section coaxially arranged, the outer diameter of the first section is larger than the diameter of the connecting hole, and the diameter of the connecting hole is larger than the outer diameter of the second section; the second section passes through the connecting hole and is connected to a fastener.

[0021] Beneficial effects: By setting the outer diameter of the first section of the output shaft to be larger than the diameter of the cutting blade connecting hole, and the diameter of the connecting hole to be larger than the outer diameter of the second section, the cutting blade can be stably placed at the transition between the first and second sections of the output shaft, thus achieving the installation and positioning of the cutting blade. At the same time, the second section passes through the connecting hole and is connected to the fastener, which can ensure that the cutting blade is firmly installed on the output shaft, effectively preventing the cutting blade from shaking or shifting during the cutting of residue, and ensuring the stability of cutting.

[0022] Secondly, this utility model also provides a dishwasher, including the aforementioned drainage component. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, a drainage assembly is provided, including a water cup 10 and a drainage pump 20. The water cup 10 includes a water cup body 11 with a water passage cavity 111 and a drainage interface 12 disposed on the side of the water cup body 11. The bottom wall of the water passage cavity 111 is provided with a first drainage outlet 13. The drainage interface 12 has a drainage channel 14 communicating with the first drainage outlet 13. The drainage pump 20 includes a drainage pump body 21, an output shaft 22 and a cutting blade 23. The drainage pump body 21 is installed in the drainage interface 12. The output shaft 22 is arranged in a horizontal direction, and one end of the output shaft 22 away from the drainage pump body 21 extends to the intersection of the drainage channel 14 and the first drainage outlet 13. The cutting blade 23 is fixed on the end of the output shaft 22.

[0036] In the above embodiment, the bottom wall of the water passage 111 is provided with a first drain outlet 13, and the drain interface 12 is provided with a drain channel 14 communicating with the first drain outlet 13. When food residue enters the drain channel 14 with the water flow through the first drain outlet 13, it naturally settles and accumulates at the bottom of the drain channel 14 under the action of gravity. When the drain pump 20 is started, its horizontally set output shaft 22 drives the cutting blade 23 to rotate, effectively cutting and crushing the food residue flowing through this area with the water flow. The crushed fine fragments are then carried by the water flow and discharged into the external drain pipe through the drain channel 14. This ensures that the food residue is fully crushed before being discharged, thereby effectively solving the problem of blockage in the external drain pipe. Furthermore, the setting of the horizontal output shaft 22 causes the rotation plane of the cutting blade 23 to extend in the vertical direction. Compared to the vertical output shaft 22 structure, this design effectively avoids the accumulation of food residue pressing on the cutting blade 23, ensuring smooth blade rotation. It requires less driving force, reducing energy consumption and saving electricity. Furthermore, during rotation, the cutting blade 23 disturbs the relatively still water layer and deposited food residue at the bottom of the channel, lifting and carrying them into the water flow. This helps prevent the formation of a difficult-to-remove silt layer at the bottom of the drainage channel 14, further ensuring its unobstructed flow. Moreover, compared to the traditional method of installing a filter screen at the bottom of the sink, it reduces the frequency of filter cleaning, ensuring smooth drainage, reducing the risk of user complaints due to poor drainage, and improving the user experience.

[0037] Specifically, the drainage component of this application is located at the bottom of the water tank, the water cup body 11 is connected to the water outlet at the bottom of the water tank, and the water passage cavity 111 inside the water cup body 11 is connected to the water outlet of the water tank.

[0038] Preferably, the output shaft 22 is disposed on the axis of the drainage channel 14.

[0039] In one embodiment, the drain pump 20 further includes a drain fan blade 24, which is fixed on the output shaft 22 and located between the drain pump body 21 and the cutting blade 23.

[0040] In the above embodiment, the rotation of the drainage fan blades 24 fixed on the output shaft 22 generates strong drainage power, which directly drives the water flow to carry the cut residue particles and discharge them efficiently from the drainage channel 14.

[0041] In one embodiment, a second drain outlet 15 is provided on the peripheral wall of the drain interface 12, and the drain fan blade 24 is located directly opposite the second drain outlet 15.

[0042] In the above embodiment, since the drainage fan blades 24 and the second drain outlet 15 are positioned correspondingly, the axial water flow generated by the rotation of the drainage fan blades 24 is directed towards the drain outlet. This eliminates ineffective turbulence in the drainage channel 14, preventing disordered circulation of debris and particles. Furthermore, it allows the water flow to directly carry the cut debris and particles, efficiently discharging them along the shortest path. This not only improves drainage efficiency but also avoids the risk of particle deposition or secondary accumulation due to flow direction deviation, ensuring the unobstructed flow of the drainage channel 14.

[0043] Specifically, the second drain outlet 15 is connected to an external drainage pipe.

[0044] In this embodiment, the second drain outlet 15 is located between the drain pump body 21 and the cutting blade 23, which prevents water carrying debris from flowing to the drain pump body 21, prevents blockage of the drain pump body 21, and ensures the normal operation of the drain pump 20.

[0045] In one embodiment, the drainage channel 14 includes a first channel 141 and a second channel 142; the top is connected to the water cup body 11; the cutting blade 23 is disposed in the first channel 141; the second channel 142 is coaxially disposed with the first channel 141, and its two ends are respectively connected to the first channel 141 and the drainage pump body 21; the second drain outlet 15 is disposed on the side wall of the second channel 142; and the drainage fan blade 24 is located in the second channel 142.

[0046] In the above embodiment, since the top of the first channel 141 is connected to the water cup body 11, and the cutting blade 23 is disposed in the first channel 141, water with residue can enter the first channel 141 and the residue is cut by the cutting blade 23. The two ends of the second channel 142 are respectively connected to the first channel 141 and the drain pump body 21. The drain fan blade 24 is disposed in the second channel 142, and the second drain outlet 15 is disposed on the side wall of the second channel 142. The cut residue particles can enter the second channel 142 with the power generated by the drain fan blade 24 and be smoothly discharged from the second drain outlet 15 with the water flow. This realizes the orderly connection between residue treatment and drainage, avoids the accumulation of residue in the drain channel 14, and ensures the smooth flow of the drainage system.

[0047] In one embodiment, the inner diameter of the first channel 141 is smaller than the inner diameter of the second channel 142.

[0048] In the above embodiment, since the first channel 141 and the second channel 142 are coaxially arranged, and the inner diameter of the first channel 141 is smaller than the inner diameter of the second channel 142, it is ensured that the residue particles after cutting can flow smoothly and efficiently from the first channel 141 into the second channel 142 with the water flow, effectively preventing the residue from accumulating at the bottom of the first channel 141 and avoiding obstruction of the flow of residue due to unreasonable structure.

[0049] In one embodiment, the drain pump body 21 is snapped into the drain port 12.

[0050] In the above embodiments, by snapping the drain pump body 21 with the drain interface 12, a quick and stable connection and separation of the drain pump body 21 and the drain interface 12 is achieved, improving assembly and maintenance efficiency. Installation or disassembly between the drain pump 20 and the drain interface 12 can be completed without additional tools, making the operation convenient and time-saving.

[0051] In one embodiment, the drain pump body 21 is provided with at least two slots 211, and the at least two slots 211 are arranged circumferentially around the drain pump body 21. The drain interface 12 is provided with at least two buckles 121, and the buckles 121 are engaged with the slots 211 one by one.

[0052] In the above embodiment, by setting at least two slots 211 and at least two buckles 121 to be connected one-to-one, the stability of the connection between the drainage pump 20 and the drainage interface 12 is ensured. Furthermore, the at least two slots 211 are arranged circumferentially around the drainage pump body 21 to ensure the uniformity of the connection force, reduce the risk of failure caused by loose connection, and ensure the reliability and stability of the drainage pump 20 during operation.

[0053] In specific embodiments, the number of buckles 121 and slots 211 is not limited. There can be two, three, or more buckles 121, and the number of slots 211 corresponds to the number of buckles 121, which can also be two, three, or more. In this embodiment, there are four buckles 121, each corresponding to one slot 211. The four buckles 121 protrude from the outer wall of the drain interface 12 and are evenly spaced around the circumference of the drain interface 12. Specifically, the four slots 211 are located on the mounting end face of the drain pump 20 and are circumferentially continuous. There is a mounting position between two adjacent slots 211. When the drain pump 20 is installed with the drain interface 12, the four buckles 121 are respectively positioned at the four mounting positions. Then, the drain pump 20 is rotated, causing the buckles 121 to slide into the corresponding slots 211, thus achieving the engagement between the drain pump 20 and the drain interface 12.

[0054] In one embodiment, the cutting blade 23 is detachably connected to the output shaft 22.

[0055] In the above embodiment, since the cutting blade 23 is detachably connected to the output shaft 22, when the cutting blade 23 is worn or damaged, the cutting blade 23 can be replaced quickly and independently without replacing or disassembling the entire drain pump 20, thus reducing the replacement cost and time cost of the cutting blade 23.

[0056] In one embodiment, the cutting blade 23 is provided with a connecting hole; the output shaft 22 includes a first section 221 and a second section 222 arranged coaxially, the outer diameter of the first section 221 is larger than the diameter of the connecting hole, and the diameter of the connecting hole is larger than the outer diameter of the second section 222; the second section 222 passes through the connecting hole and is connected to the fastener 223.

[0057] In the above embodiment, by setting the outer diameter of the first segment 221 of the output shaft 22 to be larger than the diameter of the connecting hole of the cutting blade 23, and the diameter of the connecting hole to be larger than the outer diameter of the second segment 222, the cutting blade 23 can be stably placed at the transition between the first segment 221 and the second segment 222 of the output shaft 22, thereby achieving the installation and positioning of the cutting blade 23. At the same time, the second segment 222 passes through the connecting hole and is connected to the fastener 223, which can ensure that the cutting blade 23 is firmly installed on the output shaft 22, effectively preventing the cutting blade 23 from shaking or shifting during the cutting of residue, and ensuring the stability of cutting.

[0058] Specifically, the second segment 222 can be a threaded segment, and the fastener 223 can be a nut.

[0059] In some embodiments, the cutting blades 23 are arranged in a cross shape. By arranging the cutting blades 23 in a cross shape, the cutting force can be dispersed during the cutting process, reducing local stress concentration, thereby effectively reducing blade wear and extending its service life. At the same time, the cross shape arrangement allows the blades to perform efficient cutting in multiple directions, improving cutting efficiency and ensuring the balance of cutting forces during cutting, making the cutting process more stable. A single installation can achieve multi-angle coverage, eliminating the need for frequent tool changes or tool position adjustments, and comprehensively reducing the cost of residue crushing.

[0060] In this embodiment, when the dishwasher starts working, food residue enters the first channel 141 through the water cup 10. When the dishwasher drains water, the drain pump 20 is activated. The output shaft 22 of the drain pump 20 drives the cutting blade 23 to rotate, breaking up the food residue. As the drain fan blade 24 rotates, the broken residue enters the second channel 142 with the water flow and is then discharged from the second drain outlet 15. This satisfies the dishwasher's drainage function while breaking up and discharging food residue, effectively preventing the drain pump 20 from getting stuck and the drain from becoming clogged, thus improving the product quality of the dishwasher.

[0061] According to an embodiment of the present invention, another aspect provides a dishwasher including the aforementioned drainage assembly.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
