[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] With the development of the social economy and the gradual improvement of people's living standards, people are paying more and more attention to the quality of their home life. As the second largest home appliance after washing machines, cleaning machines have the potential to become one of the essential kitchen appliances in every kitchen and a new growth point in the kitchen appliance industry.

[0040] The cleaning machine in this embodiment is described using a dishwasher as an example.

[0041] This embodiment provides a dishwasher, which includes a cabinet for holding tableware to be washed. Figures 1-3As shown, the dishwasher also includes a water cup assembly, which includes a water cup body 2 and a washing pump 3. The water cup body 2 is connected to the washing pump 3, and both the water cup body 2 and the washing pump 3 are connected to the cabinet. When the washing pump 3 is started, the water in the water cup body 2 is pumped into the water tank and sprayed out through the spray nozzle to clean the dishes.

[0042] The washing pump 3 includes a volute 31 and an impeller. The volute 31 includes a housing 311 and a spray pipe 312 tangentially disposed outside the housing 311. One end of the spray pipe 312 has an outlet and is connected to the housing 311. The impeller is rotatably disposed inside the housing 311. When the impeller rotates, the liquid inside the housing 311 is discharged from the outlet, creating a negative pressure inside the housing 311. At this time, the housing 311 can draw water from the water cup body 2 and spray the water into the tank through the spray pipe 312. The water that enters the tank to wash the dishes will flow back into the water cup body 2, thus forming a circulation.

[0043] In order to effectively filter the water used for washing dishes and thus achieve water recycling, the water cup assembly also includes a filter 1. The water cup body 2 has a filter groove 21. The filter 1 is set in the filter groove 21 and spaced apart from the side wall of the filter groove 21. The side wall of the water cup body 2 has a water inlet 23. The water inlet 23 is connected to a connecting pipe 4. The washing pump 3 is located on one side of the water cup body 2 and is connected to the filter groove 21 through the connecting pipe 4.

[0044] The water cup assembly is an important component of a dishwasher, primarily used to filter solid food residue. However, existing filters are cylindrical, meaning the filtered water can only flow from the inner wall of the filter and the water cup body to the wash pump. This results in an excessively long flow path for the filtered water to reach the wash pump, leading to low residue filtration efficiency.

[0045] This embodiment provides a filter, such as Figure 3 and Figure 4 As shown, the filter 1 includes a filter sleeve 11 and a flow guiding assembly 12. The filter sleeve 11 has an accommodating space and a first filter hole 111 is formed on the side wall of the filter sleeve 11. The flow guiding assembly 12 is disposed in the accommodating space and both ends of the flow guiding assembly 12 are open to the side wall of the filter sleeve 11. The side wall of the flow guiding assembly 12 has a filter hole.

[0046] After the water used for washing dishes enters the water cup assembly, it is located in the accommodating space of the filter sleeve 11. The side wall of the filter sleeve 11 can filter the water after washing. Some of the filtered water enters the space between the filter sleeve 11 and the water cup body 2, and then enters the water inlet 23. The other filtered water enters the flow guide assembly 12 through the filter holes on the side wall of the flow guide assembly 12, and enters the water inlet 23 along the flow guide assembly 12.

[0047] By incorporating the flow guide component 12, this water cup assembly increases the filtration area of ​​the filter 1, thereby improving the filter residue efficiency and reducing the amount of filter residue per unit filtration area, thus solving the problem of residue clogging.

[0048] At this time, the filtered water can flow not only between the filter sleeve 11 and the water cup body 2, but also enter through the first water pipe 121 of the flow guide assembly 12 and flow out through the second water pipe 122. Since the angle between the first water pipe 121 and the second water pipe 122 is greater than 90°, it can reduce the resistance of water flow and allow water at the far end to flow out of the second water pipe 122 quickly, thereby improving the water suction effect of the washing pump 3 and improving energy efficiency.

[0049] In this embodiment, the flow guiding component 12 includes a first water pipe 121 and a second water pipe 122 that are connected to each other. Both the first water pipe 121 and the second water pipe 122 are disposed within the accommodating space and open onto the side wall of the filter sleeve 11. The filter holes of the flow guiding component 12 are opened on the side wall of the first water pipe 121. For ease of description, the second water pipe 122 faces the water inlet 23, and the filter hole on the side wall of the first water pipe 121 is referred to as the second filter hole 1211. Water in the accommodating space can directly enter the first water pipe 121 through the second filter hole 1211, which not only completes filtration but also increases the number of water flow paths, facilitating the rapid arrival and exit of water from the second water pipe 122. Moreover, the water filtered by the filter sleeve 11 can flow not only between the filter sleeve 11 and the water cup body 2 but also enter through the first water pipe 121 and exit through the second water pipe 122.

[0050] It is understandable that the filter holes of the flow guiding component 12 can also be opened on the side wall of the second water pipe 122. For ease of description, the filter holes on the side wall of the second water pipe 122 are referred to as the third filter holes 1221. The water in the accommodating space can also enter the second water pipe 122 directly through the third filter holes 1221 and be quickly sucked in by the washing pump 3.

[0051] Furthermore, the angle between the first water pipe 121 and the second water pipe 122 is greater than 90°, which can reduce the resistance of water flow in the guide assembly 12 and allow water at the far end to flow out of the second water pipe 122 quickly, thereby improving the water suction effect of the washing pump 3 and improving energy efficiency.

[0052] To increase the water flow rate of the first water pipe 121, the axial dimension of the first water pipe 121 along the filter sleeve 11 is larger than its circumferential dimension. This larger axial dimension allows water at different heights within the containment space to flow simultaneously to the washing pump 3, improving the water suction effect of the washing pump 3. Similarly, the axial dimension of the second water pipe 122 along the filter sleeve 11 is larger than its circumferential dimension.

[0053] like Figure 2 As shown, the side wall of the water cup body 2 has at least two water inlets 23, and the flow guiding assembly 12 includes two second water pipes 122, with the end of each second water pipe 122 away from the first water pipe 121 facing one water inlet 23. In this water cup assembly, when the washing pump 32 is started, the washing pump 32 can draw water from the water cup body 2 through at least two water inlets 23. This reduces the cross-sectional area of ​​each water inlet 23 while maintaining the same water flow rate, thereby increasing the water pressure of the washing pump 3 when drawing water and improving the washing effect.

[0054] In this embodiment, the washing pump 3 may have only one inlet, which is connected to all the water inlets 23, and all the water in the water cup body 2 enters the washing pump 3 through this inlet; the washing pump 3 may also have at least two inlets, which are connected to the water inlets 23 one by one, and the water in the water cup body 2 enters the washing pump 3 through the corresponding inlet.

[0055] Each water inlet 23 is connected to a connecting pipe 4, and the inlet and water inlet 23 are connected by the connecting pipe 4. Preferably, the connecting pipe 4 is offset and forms an angle with the side wall of the water cup body 2. The water cup body 2 has multiple axial sections, and the axial sections of the connecting pipe 4 and the water cup body 2 that are parallel to the connecting pipe 4 are staggered, that is, the angle between the connecting pipe 4 and the side wall of the water cup body 2 is not 90°.

[0056] At this time, when the suction in the connecting tube 4 draws the food residue to the position corresponding to the water inlet 23 of the filter element, the suction force exerted on the food residue against the first filter screen 8 is a component of the suction force in the connecting tube 4. Therefore, this suction force is relatively small and will not cause the food residue to be adsorbed onto the first filter screen 8. Moreover, the other component of the suction force in the connecting tube 4 is tangential along the side wall of the water cup body 2. This component causes the food residue blocked by the first filter screen 8 to move along the circumference of the first filter screen 8, further preventing the food residue from accumulating at the position corresponding to the water inlet 23 of the first filter screen 8 and causing blockage.

[0057] In this embodiment, an even number of water inlets 23 are provided on the side wall of the water cup body 2, and the even number of water inlets 23 are mirror-symmetrical with respect to one axial section of the water cup body 2. Figure 3 As shown, the axial section is the plane AA where the axis of the water cup body 2 and the axis of the washing pump 3 are located. The even number of water inlets 23 are mirror symmetrical, which ensures that all the connecting pipes 4 are not perpendicular to the side wall of the water cup body 2, thus effectively avoiding the accumulation of food residue and blocking the water flow, and improving the efficiency of the washing pump 3.

[0058] Preferably, the cross-sectional shape of the connecting pipe 4 can be circular, elliptical, or rectangular.

[0059] like Figure 3 and Figure 4 As shown, the flow guiding assembly 12 includes two second water pipes 122 and one first water pipe 121, with the angle between the first water pipe 121 and the two second water pipes 122 being 110° to 130°. At this time, the two second water pipes 122 can respectively face the water inlet 23 on one side of plane AA, while the first water pipe 121 extends along plane AA in a direction away from the washing pump 3. This allows the flow guiding assembly 12 to draw water from the farthest point into the first water pipe 121, and then through the two second water pipes 122 into the corresponding water inlet 23, improving the water suction effect of the washing pump 3. Specifically, the angle between the first water pipe 121 and the two second water pipes 122 can be 110°, 115°, 120°, 125°, or 130°.

[0060] To improve the overall strength of the flow guiding assembly 12, the filter 1 also includes a reinforcing structure 13. The first water pipe 121 and the second water pipe 122 are both provided with the reinforcing structure 13, and the reinforcing structure 13 of the first water pipe 121 and the reinforcing structure 13 of the second water pipe 122 are fixedly connected.

[0061] like Figure 1 and Figure 2 As shown, the washing pump 3 also includes a pressure measuring element 5, which is located at the other end of the spray pipe 312 relative to the water outlet. The pressure measuring element 5 can measure the pressure inside the spray pipe 312 to determine whether the water pressure meets the standard, so as to ensure that the water pumped into the water tank has sufficient impact force and ensure the cleaning effect.

[0062] like Figure 2 and Figure 4 As shown, a sealing ring 14 protrudes from the side wall of the filter 1, and a sealing platform 22 protrudes from the side wall of the filter tank 21. The sealing ring 14 is disposed on the sealing platform 22 and is sealed to the sealing platform 22. As the dishwasher operates, a large amount of food residue will remain inside the filter 1. The sealed connection between the filter 1 and the sealing ring 14 can prevent food residue from entering the area between the filter 1 and the water cup body 2, and prevent food residue from re-entering the cabinet with the washing pump 3.

[0063] In other embodiments, the side wall of the filter tank 21 may be provided with a sealing ring 22, and the filter 1 may be disposed on the sealing ring 22 and sealed and connected to the sealing ring 22.

[0064] It is worth noting that the sealing ring 14 is an elastic structure to ensure a good sealing effect.

[0065] Understandably, after the dishwasher stops working, it is necessary to empty the food residue from the water cup body 2 to ensure the dishwasher is clean. Figures 1-3As shown, to achieve the above purpose, the water cup assembly also includes a drain pump 6, which is connected to the bottom of the water cup body 2, and water and food residue inside the water cup body 2 can be discharged through the drain pump 6.

[0066] like Figure 3 As shown, to further improve the cleaning ability of the dishwasher, the washing pump 3 also includes a heating element 32, which is disposed inside the volute 31. The heating element 32 can heat the water entering the washing pump 3, and hot water can greatly improve the cleaning ability of oil stains.

[0067] Furthermore, the heating element 32 is annular and coaxially arranged with the washing pump 3, which can increase the contact area between the heating element 32 and the water, increase the heating rate, and ensure that the water is heated evenly, avoiding local overheating and scalding the tableware.

[0068] like Figure 1 and Figure 3 As shown, at least one connecting pipe 4 has a temperature measuring element 7 installed on its side wall, with the measuring end of the element 7 located inside the connecting pipe 4. The temperature measuring element 7 measures the temperature of the water flowing through the connecting pipe 4 to determine if the water temperature meets the requirements. Once the water temperature reaches the required level, the heating element 32 can be turned off, thus saving energy. Alternatively, the heating element 32 can be turned off only temporarily. When the temperature measuring element 7 detects that the water temperature has dropped to a certain set temperature, the heating element 32 can be turned back on to ensure continuous cleaning capability.

[0069] like Figure 1 As shown, the water cup assembly also includes a filter screen 8. The top of the water cup body 2 has an opening, and the filter screen 8 is located on the top of the water cup body 2 and seals the opening. The washing pump 3 pumps water into the tank to wash the tableware, and then the water flows back into the water cup body 2 through the opening. At this time, the filter screen 8 can perform primary filtration to filter out larger food residues and prevent clogging of the filter 1.

[0070] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
