[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] The cleaning machine of this embodiment is described by taking a dishwasher as an example.

[0037] This embodiment provides a dishwasher, which includes a box body, and the box body is used to place dishes to be washed. Figure 1 to Figure 3 As shown, the dishwasher also includes a water cup assembly, which includes a water cup body 2 and a washing pump 3, wherein the water cup body 2 is connected to the washing pump 3, and the water cup body 2 and the washing pump 3 are both connected to the tank. When the washing pump 3 is started, the water in the water cup body 2 will be pumped into the water tank and sprayed out through the spray head to clean the tableware.

[0038] The washing pump 3 includes a volute 31 and an impeller. The volute 31 includes a housing 311 and a water spray pipe 312 arranged on the outside of the housing 311 along the tangent direction of the housing 311. A water outlet is opened at one end of the water spray pipe 312. The water spray pipe 312 is connected to the housing 311. The impeller is rotatably arranged in the housing 311. When the impeller rotates, the liquid in the housing 311 is discharged from the water outlet, so that negative pressure is generated in the housing 311. At this time, the housing 311 can absorb water from the water cup body 2 and spray the water into the box through the water spray pipe 312. The water that enters the box to wash the dishes will flow back into the water cup body 2, thereby forming a cycle.

[0039] In order to effectively filter the water used for washing dishes and thus realize the recycling of water, the water cup assembly also includes a filter 1, a water cup body 2 is provided with a filter tank 21, the filter 1 is arranged in the filter tank 21 and is spaced apart from the side wall of the filter tank 21, a water suction port 23 is provided on the side wall of the water cup body 2, the water suction port 23 is connected to a connecting pipe 4, a washing pump 3 is located on one side of the water cup body 2, and the washing pump 3 is connected to the filter tank 21 through the connecting pipe 4.

[0040] The water cup assembly is an important component of the dishwasher, mainly used to filter solid residues. However, the existing filter is a cylindrical filter, and the filtered water can only flow from the filter and the inner wall of the water cup body to the washing pump, which results in a long flow path from the filtered water to the washing pump and low residue filtering efficiency.

[0041] 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 guide component 12. The filter sleeve 11 is provided with an accommodating space. The side wall of the filter sleeve 11 is provided with a first filter hole 111. The flow guide component 12 is arranged in the accommodating space. Both ends of the flow guide component 12 are opened on the side wall of the filter sleeve 11. The side wall of the flow guide component 12 is provided with a filter hole.

[0042] After the water 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 washed water. Part of the water in the filter sleeve 11 is filtered when passing through the first filter hole 111, and thus flows out of the filter 1. The water in other filter sleeves 11 can also enter the guide assembly 12 through the filter holes on the side wall of the guide assembly 12, and flow out of the filter 1 along the opening of the side wall of the filter sleeve 11 of the guide assembly 12. The filtered water re-enters the washing pump 3 through the water suction port 23, so that the water can be recycled for washing.

[0043] The water cup assembly increases the filtering area of ​​the filter 1 for water by providing the guide assembly 12, thereby improving the filtering residue efficiency and reducing the amount of filtered residue per unit filtering area, thereby solving the problem of residue clogging.

[0044] At this time, the filtered water can not only flow 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°, the resistance of the water flow can be reduced and the water at the far end can flow out of the second water pipe 122 quickly, thereby improving the water absorption effect of the washing pump 3 and improving energy efficiency.

[0045] In this embodiment, the flow guide assembly 12 includes a first water pipe 121 and a second water pipe 122 that are connected. The first water pipe 121 and the second water pipe 122 are both arranged in the accommodating space and open to the side wall of the filter sleeve 11. The side wall of the first water pipe 121 is provided with a second filter hole 1211. For the convenience of description, the second water pipe 122 faces the water suction port 23, and the filter hole on the side wall of the first water pipe 121 is referred to as the second filter hole 1211. The water in the accommodating space can directly enter the first water pipe 121 through the second filter hole 1211, which can not only complete the filtration, but also increase the number of water flow paths, so that the water can quickly reach and flow out of the second water pipe 122. Moreover, the water filtered by the filter sleeve 11 can not only flow between the filter sleeve 11 and the water cup body 2, but also enter through the first water pipe 121 and flow out through the second water pipe 122.

[0046] It is understandable that the filter hole of the guide component 12 can also be opened on the side wall of the second water pipe 122. For the convenience of description, the filter hole on the side wall of the second water pipe 122 is called the third filter hole 1221. The water in the accommodating space can also directly enter the second water pipe 122 through the third filter hole 1221 and be quickly sucked into the washing pump 3.

[0047] Furthermore, the angle between the first water pipe 121 and the second water pipe 122 is greater than 90°, which can not only reduce the resistance of the water flow in the guide component 12, but also enable the water at the far end to quickly flow out of the second water pipe 122, thereby improving the water absorption effect of the washing pump 3 and improving energy efficiency.

[0048] In order to increase the water flow rate of the first water pipe 121, the dimension of the first water pipe 121 along the axial direction of the filter sleeve 11 is larger than the dimension of the first water pipe 121 along the circumferential direction of the filter sleeve 11. The first water pipe 121 has a larger dimension along the axial direction of the filter sleeve 11, and can simultaneously flow water at different heights in the accommodating space to the washing pump 3, thereby improving the water absorption effect of the washing pump 3. Similarly, the dimension of the second water pipe 122 along the axial direction of the filter sleeve 11 is larger than the dimension of the second water pipe 122 along the circumferential direction of the filter sleeve 11.

[0049] like Figure 2 As shown, at least two water suction ports 23 are provided on the side wall of the water cup body 2, and the flow guide assembly 12 includes two second water pipes 122, and one end of each second water pipe 122 away from the first water pipe 121 faces one water suction port 23. In the water cup assembly, when the washing pump 3 is started, the washing pump 3 can absorb water from the water cup body 2 through at least two water suction ports 23, and the cross-sectional area of ​​each water suction port 23 can be reduced under the premise of ensuring the same water flow rate, thereby increasing the water pressure of the washing pump 3 when absorbing water and improving the washing effect.

[0050] In this embodiment, the washing pump 3 can be provided with only one inlet, which is connected to all the water suction ports 23, and the water in the water cup body 2 enters the washing pump 3 through the inlet; the washing pump 3 can also be provided with at least two inlets, which are connected to the water suction ports 23 one by one, and the water in the water cup body 2 enters the washing pump 3 through the corresponding inlets.

[0051] Each water inlet 23 is connected to a connecting pipe 4, and the inlet and the water inlet 23 are connected through the connecting pipe 4. Preferably, the connecting pipe 4 is offset with the side wall of the water cup body 2 at an angle. The water cup body 2 has multiple axial sections, and the connecting pipe 4 and the axial sections of the water cup body 2 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°.

[0052] At this time, when the suction force in the connecting tube 4 adsorbs the food residue to the position of the filter element corresponding to the water suction port 23, the suction force on the food residue facing the first filter 8 is the component force of the suction force in the connecting tube 4, so the suction force is relatively small and the food residue will not be adsorbed on the first filter 8. Moreover, the direction of another component force of the suction force in the connecting tube 4 is along the tangent direction of the side wall of the water cup body 2, and this component force makes the food residue blocked by the first filter 8 move along the circumference of the first filter 8, further preventing the accumulation of food residue at the position of the first filter 8 corresponding to the water suction port 23 and causing blockage.

[0053] In this embodiment, the side wall of the water cup body 2 is provided with an even number of water suction ports 23, and the even number of water suction ports 23 are mirror-symmetrical with respect to an 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 suction ports 23 are mirror-symmetrical to ensure that all connecting pipes 4 are not perpendicular to the side wall of the water cup body 2, thereby effectively avoiding the accumulation of food residues to block the water flow and improving the efficiency of the washing pump 3.

[0054] Preferably, the cross-sectional shape of the connecting pipe 4 may be circular, elliptical or rectangular.

[0055] like Figure 3 and Figure 4As shown, the flow guide assembly 12 includes two second water pipes 122 and one first water pipe 121, and the angles between the first water pipe 121 and the two second water pipes 122 are 110° to 130°. At this time, the two second water pipes 122 can respectively face the water suction port 23 on one side of the plane AA, and the first water pipe 121 extends along the plane AA in a direction away from the washing pump 3, so that the flow guide assembly 12 can suck the farthest water into the first water pipe 121, and enter the corresponding water suction port 23 through the two second water pipes 122, thereby 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°.

[0056] It is worth noting that the accommodating space is divided into at least two sub-spaces by the guide assembly 12, and the side wall of the filter sleeve 11 is provided with a first filter hole 111 corresponding to each sub-space, thereby ensuring that the water in the accommodating space can be filtered through the shortest path, thereby improving the filtering efficiency.

[0057] In this embodiment, the accommodating space is divided into three sub-spaces.

[0058] Furthermore, the side walls of the flow guide assembly 12 are provided with filter holes corresponding to each subspace. That is, the two side walls of the first water pipe 121 facing the subspace are provided with second filter holes 1211, and the two side walls of the second water pipe 122 facing the subspace are provided with third filter holes 1221, so as to increase the filter area of ​​the water in the subspace.

[0059] In order to improve the overall strength of the guide 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 a 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.

[0060] like Figure 1 and Figure 2 As shown, the washing pump 3 also includes a pressure measuring device 5, which is arranged at the other end of the water spray pipe 312 relative to the water outlet. The pressure measuring device 5 can measure the pressure in the water spray pipe 312, so as 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 to ensure the cleaning effect.

[0061] like Figure 4As shown, a sealing ring 14 is convexly provided on the side wall of the filter 1, and the sealing ring 14 is used to be sealed and connected with the inner wall of the filter tank 21. In this embodiment, the accommodating space passes through the axial ends of the water cup body 2 in the vertical direction, and the filtered residue is discharged through the bottom of the water cup body 2. As the dishwasher is running, a large amount of food residue will remain inside the filter 1, and the sealed connection between the filter 1 and the sealing ring 14 can prevent the food residue from entering the position between the filter 1 and the water cup body 2, and prevent the food residue from re-entering the box along with the washing pump 3.

[0062] like Figure 2 As shown, in order to facilitate the installation of the filter 1 , a sealing platform 22 is protruding from the side wall of the filter tank 21 , and the sealing ring 14 is disposed on the sealing platform 22 and is sealedly connected to the sealing platform 22 .

[0063] In other embodiments, a sealing ring 14 may be protruding from the side wall of the filter tank 21 , and the filter 1 is disposed on the sealing ring 14 and sealedly connected to the sealing ring 14 .

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

[0065] It is understandable that after the dishwasher stops working, the food residue in the cup body 2 needs to be discharged to ensure the cleanliness of the dishwasher. Figure 1 to Figure 3 As shown, in order to achieve the above purpose, the water cup assembly also includes a drainage pump 6, which is connected to the bottom of the water cup body 2, and the water and food residues in the water cup body 2 can be discharged through the drainage pump 6.

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

[0067] Furthermore, the heating element 32 is annular and is coaxially arranged with the washing pump 3, which can not only increase the contact area between the heating element 32 and water and increase the heating rate, but also ensure that the water is heated evenly to avoid local overheating and scalding the tableware.

[0068] like Figure 1 and Figure 3As shown, at least one side wall of the connecting pipe 4 is provided with a temperature measuring member 7, and the measuring end of the temperature measuring member 7 is located inside the connecting pipe 4. The temperature measuring member 7 can measure the temperature of the water flowing through the connecting pipe 4 to determine whether the water temperature meets the requirement. When the water temperature meets the requirement, the heating member 32 can be turned off to save energy. Of course, the heating member 32 can also be turned off temporarily. When the temperature measuring member 7 detects that the water temperature drops to a certain set temperature, the heating member 32 can be turned on again for heating to ensure continuous cleaning ability.

[0069] like Figure 1 As shown, the water cup assembly also includes a filter 8. An opening is provided at the top of the water cup body 2. The filter 8 is provided at the top of the water cup body 2 and covers the opening. The washing pump 3 pumps water into the box to wash the dishes, and then the water flows back into the water cup body 2 through the opening. At this time, the filter 8 can perform primary filtration to filter larger food residues to prevent clogging of the filter 1.

[0070] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
