In an embodiment of the present invention, as shown in fig. 1 to 5, the filter assembly includes:

Microfilter 30, microfilter 30 rotatable install in the return water chamber 11, microfilter 30's periphery wall with form return water clearance 40 between the inner wall in return water chamber 11, be equipped with water conservancy diversion piece 31 on microfilter 30's the periphery wall, water conservancy diversion piece 31 has the ascending spigot surface 311 of slope.

In this embodiment, the dish washer includes inner bag subassembly and drinking cup 10 subassembly, and the inner bag subassembly is used for placing the tableware, and drinking cup 10 subassembly is used for rinsing the tableware in the inner bag subassembly and accomplishes the circulation in water route, is equipped with the erection opening on the inner bag bottom plate of inner bag subassembly, and drinking cup 10 subassembly sets up in erection opening department. The water cup 10 component comprises a water cup 10, a filter screen, a washing pump, a spray arm component and a filter component, wherein the top surface of the water cup 10 is recessed downwards to form a water return cavity 11, the filter screen is arranged at the cavity opening of the water return cavity 11, the filter component penetrates through the filter screen and extends into the water return cavity 11, the spray arm component is installed in the non-recessed area of the top surface of the water cup 10, and the washing pump is communicated with the water return cavity 11 and the spray arm component; when the dishwasher works, the spray arm component sprays water to wash tableware in the inner container component, the washed water reaches the filter screen along with residues, one part of water directly enters the water return cavity 11 through the filter screen, the other part of water and the residues enter the water return cavity 11 after passing through the filter component, the washed water is collected in the water return cavity 11, is sucked into the washing pump through the water outlet 111, enters the spray arm component from the washing pump, and then is sprayed out of the spray arm component again, and the cyclic utilization of water resources is completed.

the filter screen is arranged around the circumferential surface of the micro filter 30, and after the dishwashing water enters the micro filter 30, residues are filtered by the filter screen and are left in the micro filter 30 in the process of circularly entering the washing pump; when the dish washing water enters the draining condition, the residue is discharged from the draining hole at the bottom of the micro filter 30 along with the dish washing water. In the process of the circulation of the dish washing water, a part of the residue is adsorbed on the filter screen, which results in the water being unable to be discharged normally under the water discharge condition, and the adsorption position of the residue is usually the position of the micro filter 30 near the water outlet 111, if the adsorption of the residue is not dispersed, the adsorption amount of the residue on a single position of the micro filter 30 is about large, thereby causing the micro filter 30 to be partially blocked, and affecting the filtering effect of the micro filter 30.

In this embodiment, the guide vane 31 is provided on the outer peripheral wall of the micro filter 30, and the guide surface 311 of the guide vane 31 is inclined upward, and at least one, preferably a plurality of guide vanes 31 are provided. The guide surface 311 is used to receive the impact of the water flow and convert the impact of the water flow into a thrust in a transverse direction. Note that the water outlet 111 is generally opened at a lower end of a side wall of the return chamber 11 to sufficiently suck the water in the return chamber 11. In the process that the washing pump sucks water from the water outlet 111, water in the water return cavity 11 flows downwards in the longitudinal direction and also flows towards the side where the water outlet 111 is located in the transverse direction, the split flow of the downward flow of the water flow acts on the inclined guide surface 311 to generate a thrust on the guide surface 311, the thrust forms a transverse component force under the decomposition action of the guide surface 311, the component force pushes the guide vane 31 in the transverse direction, and the component force pushes the microfilter 30 to integrally rotate because the guide vane 31 is connected to the outer peripheral wall of the microfilter 30 and is tangent to the part of the microfilter 30 connected with the guide vane 31. The rotating microfilter 30 can change the position adjacent to the water outlet 111, indirectly dispersing the residue on different positions of the microfilter 30, i.e. preventing the residue from being concentrated on a single position, thereby preventing the microfilter 30 from being partially blocked, facilitating the cleaning of the residue and improving the overall stability of the dishwasher.

in addition, the flow deflector 31 can also form a resistance effect on the water flowing to the water outlet 111, so as to reduce the speed of water entering the water outlet 111, thereby avoiding the liquid level at the water outlet 111 in the water return cavity 11 from being reduced too fast compared with other positions, i.e. the reduction speed of the liquid level in the water return cavity 11 is more balanced, so as to avoid the liquid level at the water outlet 111 from being lower than the upper edge of the water outlet 111 too fast in the water outlet process, thereby preventing the air from entering the washing pump through the water outlet 111 to cause the reduction of the water flow and the water pressure entering the spray arm assembly, and improving the overall washing effect of the dishwasher.

The rotary microfilter 30 prevents the residue from being intensively adsorbed at a single position, thereby facilitating the cleaning of the residue and improving the cleaning effect of the residue. In addition, the flow deflector 31 can form resistance to water flow, so that the speed of water flow flowing through the water outlet 111 is reduced, the phenomenon that the liquid level at the water outlet 111 is too fast lower than the upper edge of the water outlet 111 is avoided, air is prevented from entering the washing pump through the water outlet 111, the water flow and the water pressure entering the spray arm are prevented from being reduced, and the washing effect of the dish washing machine is improved.

In this embodiment, the number of the guide vanes 31 is at least 3, the plurality of guide vanes 31 are arranged at intervals along the circumferential direction of the micro filter 30 and are located at the same height, and the guide surfaces 311 and the inclination angles of the plurality of guide vanes 31 are the same. Since the plurality of baffles 31 are connected to the outer peripheral wall of the micro-filter 30, the component force of the water flow in the transverse direction is tangential to the outer peripheral wall of the micro-filter 30, which further increases the thrust on the micro-filter 30, thereby facilitating the rotation of the micro-filter 30.

Further, the angle formed by the guide surface 311 and the axis of the micro filter 30 is 10 ° to 80 °. In this embodiment, in order to make the downward water flow have a sufficient action area with the guide surface 311 of the deflector 31 and generate a sufficient component force in the lateral direction, the guide surface 311 should have a reasonable inclination angle to more smoothly push the microfilter 30 to rotate by the water flow.

The fixing ring 33 is positioned between the two support rings, is connected with each connecting strip and is used for providing a mounting position for the flow deflector 31; the flow deflectors 31 are connected to the fixing ring 33, so that not only can the flow deflectors 31 have enough number, but also the occupied area of the fixing ring 33 for water through holes is reduced, and the micro-filter 30 has enough water through area.

Further, the guide vane 31 is integrally provided with the fixing ring 33. In this embodiment, the baffle 31 and the fixing ring 33 are integrally formed, so that the production process can be reduced, and the production efficiency can be improved.

further, as shown in fig. 4, the opening direction of the water outlet 111 is tangential to the outer circumferential surface of the micro filter 30 of the filter assembly. In this embodiment, the opening direction of the water outlet 111 is tangent to the outer circumferential surface of the micro filter 30, so that water in the water return chamber 11 acts on the flow deflector 31 connected to the outer circumferential wall of the micro filter 30 more in the process of flowing to the water outlet 111 in the transverse direction, thereby pushing the micro filter 30 to rotate integrally more smoothly.

Further, as shown in fig. 1, in the opening direction of the water outlet 111, the guide surface 311 of the guide vane 31 of the filter assembly faces away from the water outlet 111. In this embodiment, the guide surface 311 of the baffle 31 is away from the water outlet 111 in the opening direction of the water outlet 111, so that the lateral component force generated on the guide surface 311 by the downward split flow and the acting force of the lateral split flow on the guide surface 311 are directed to the same direction, and the two forces directed to the same direction can more effectively push the micro-filter 30 to rotate, thereby improving the rotation effect of the micro-filter 30.

Further, as shown in fig. 3 and 4, the water cup 10 assembly further includes a cleaning water path, a cleaning inlet 112 communicated with the cleaning water path is further opened on a side wall of the water return chamber 11, and the cleaning inlet 112 faces the micro filter 30 of the filter assembly. In this embodiment, the cleaning water path is used to wash the micro filter 30 to clean the residue adsorbed on the filter screen of the micro filter 30, so as to clean the micro filter 30 and prolong the service life of the filter screen of the micro filter 30. The water in the washing water path can be supplied to an external water source, and can also be recycled in the water return cavity 11, the water in the washing water path enters the water return cavity 11 through the washing inlet 112 and is sprayed to the micro-filter 30, and the micro-filter 30 rotates in the water return cavity 11, so that the washing area of the micro-filter 30 can be increased through the rotation of the micro-filter 30, and the washing effect is improved.

In another embodiment of the present invention, as shown in fig. 6 to 8, a water pumping port 113 is further opened on the side wall of the water return chamber 11, the cleaning water path may include a water driving device, the water inlet 102 of the water driving device is communicated with the water pumping port 113, the water outlet 111 of the water driving device is communicated with the cleaning inlet 112, so that the water in the water return chamber 11 flows out through the water pumping port 113 and is sprayed back to the water return chamber 11 through the cleaning inlet 112.

In this embodiment, the water driving device may include a water pumping part for pumping the water in the return water chamber 11 from the water pumping port 113 and a water feeding part for spraying the pumped water back to the return water chamber 11 from the washing inlet 112 to wash the micro filter 30 installed in the return water chamber 11. It should be noted that, at this time, the inner wall of the water return cavity 11 is simultaneously provided with the water outlet 111, the cleaning inlet 112 and the water pumping port 113, and compared with the method in the prior art that water flows out from the water outlet 111 and then flows to the cleaning inlet 112, the embodiment can avoid the reduction of the water quantity and the water pressure of the water entering the spray arm assembly due to the diversion, so as to improve the cleaning effect of the dishwasher; meanwhile, the installation position of the water driving device is independent of the position of the washing pump, so that the water driving device has more installation space, the space below the inner container of the dish washing machine is fully utilized, and the space utilization rate is improved.

The utility model discloses drinking cup 10 subassembly is through seting up mouth 113 and washing entry 112 of drinking water at the lateral wall in return water chamber 11, and through water drive arrangement with the water in return water chamber 11 through draw water mouth 113 take out back rethread washing entry 112 spout return water chamber 11, from this, can wash the microfilter 30 of installing in return water chamber 11, avoid the water split with the washing pump, thereby the water yield and the water pressure of washing pump rivers have been improved, water drive arrangement's installation scope has still been enlarged simultaneously, the space utilization of dish washer installation space has been improved.

further, as shown in fig. 8, the water driving device includes a pressure pump 50, the pressure pump 50 includes a water pumping end 51 and a water feeding end 52, the water pumping end 51 is communicated with the water pumping port 113, and the water feeding end 52 is communicated with the cleaning inlet 112. In this embodiment, the pressure pump 50 comprises a housing and a pump wheel arranged in the housing, the water pumping end 51 is located at the end wall of the housing, and the water feeding end 52 is located at the peripheral wall of the housing, so that the pressure pump 50 pumps water from the water pumping port 113 and then directly feeds the water to the cleaning inlet 112, the structure of the water driving device is simplified, and the overall structure of the assembly of the water cup 10 is simplified.

further, as shown in fig. 8, the pressure pump 50 is disposed adjacent to the cleaning inlet 112, and the water driving device further includes a connection pipe 60 connecting the pumping port 113 and the pumping end 51. In this embodiment, the water supply end 52 of the pressure pump 50 is directly connected to the cleaning inlet 112, and the water outlet end of the pressure pump 50 is connected to the water outlet 113 through the connection pipe 60. The placement of the booster pump 50 adjacent the purge inlet 112 effectively reduces the flow path of water from the booster pump 50 to the purge inlet 112, thereby maintaining sufficient power to flush the microfilter 30 as the water enters the return chamber 11.

Further, as shown in fig. 8, the cross-sectional width of the cleaning inlet 112 is gradually reduced from the outside to the inside of the water return chamber 11. In the embodiment, the cleaning inlet 112 extends along the longitudinal direction, and the cross-sectional width of the cleaning inlet 112 is gradually reduced from outside to inside, so that the water inlet area passing through the cleaning inlet 112 can be reduced by limiting the shape of the cleaning inlet 112, and the water inlet kinetic energy can be increased; meanwhile, the washing inlet 112 extends in the longitudinal direction, and can maintain the washing area of the water flow on the micro-filter 30 in the longitudinal direction, so as to improve the washing effect on the micro-filter 30.

Further, as shown in fig. 8, the water cup 10 assembly further includes a flow guiding member 70 embedded in the cleaning inlet 112, the flow guiding member 70 has a water passing channel 71, and a cross-sectional width of the water passing channel 71 is gradually reduced from the outside to the inside of the water returning cavity 11. In this embodiment, the baffle 70 is configured to increase the pressure of the inlet water by reducing the area of the inlet water flowing through the cleaning inlet 112 to further enhance the flushing effect of the micro-filter 30.

Further, as shown in fig. 6 to 8, the water cup 10 assembly further includes a micro filter 30 installed in the water return chamber 11, and an inner wall of the water return chamber 11, where the cleaning inlet 112 is opened, protrudes toward the inside of the water return chamber 11. In this embodiment, the portion of the inner wall of the water return chamber 11, which is provided with the cleaning inlet 112, protrudes toward the inside of the water return chamber 11, so that the distance between the cleaning inlet 112 and the micro-filter 30 can be reduced, and therefore, water can be sprayed out from the cleaning inlet 112 and then acts on the micro-filter 30 more quickly, and the time disturbed by water in the water return chamber 11 is reduced, so as to further improve the washing effect on the micro-filter 30.

Further, as shown in fig. 8, the micro filter 30 may be rotatably installed in the water return chamber 11, and the opening direction of the cleaning inlet 112 is deviated from the axial center of the micro filter 30. In the present embodiment, the micro filter 30 is rotatably installed in the water return chamber 11, so that the micro filter 30 can be changed to a position facing the cleaning inlet 112, thereby increasing the spray position and spray area of the water flow of the cleaning inlet 112 to the micro filter 30. The opening direction of the cleaning inlet 112 deviates from the axis of the micro-filter 30, so that when the cleaning water flow acts on the micro-filter 30, a component force passing through the tangential direction of the outer peripheral wall of the micro-filter 30 is generated, the micro-filter 30 is pushed to rotate, the cleaning area is increased by pushing the micro-filter 30 to rotate while the water flow of the cleaning inlet 112 washes the micro-filter 30, and the cleaning effect is improved.

Further, as shown in fig. 8, a water outlet 111 is further formed in a side wall of the water return cavity 11, and the water pumping port 113 is disposed away from the water outlet 111. In this embodiment, the pumping port 113 is disposed away from the water outlet 111, so that a water robbing phenomenon occurring when the water outlet 111 and the pumping port 113 absorb water simultaneously can be avoided. If the pumping port 113 is adjacent to the water outlet 111, the liquid level at the pumping port 113 and the water outlet 111 will decrease too fast, resulting in the liquid level at the pumping port 113 and the water outlet 111 being too fast lower than the upper edge of the pumping port 113 and the water outlet 111, so that air will enter the washing pump and the pressure pump 50, resulting in the decrease of the water pressure of the washing water flow and the cleaning water flow. Therefore, by disposing the pumping port 113 away from the water outlet 111, air can be prevented from entering the washing pump or the pressurizing pump 50 to improve the washing effect of the dishwasher and the washing effect of the micro filter 30.

Further, the opening direction of the cleaning inlet 112 is the same as the opening direction of the water outlet 111. In this embodiment, the cleaning inlet 112 and the water outlet 111 are located on two sides of the axis of the micro filter 30, the cleaning inlet 112 sprays water, the water outlet 111 sucks water, the cleaning water flow at the cleaning inlet 112 pushes the micro filter 30 to rotate, and the water flow flowing to the water outlet 111 also pushes the micro filter 30 to rotate along the same circumferential direction, so that the rotation effect of the micro filter 30 is further improved.

In another embodiment of the present invention, as shown in fig. 9 to 13, a first drainage hole 114 is opened at the bottom of the water return cavity 11; the bottom of the micro filter 30 is provided with a second drainage hole 33 communicated with the first drainage hole 114; the cup 10 assembly further includes a blocking cover 80 for opening or closing the second drain hole 33.

In the embodiment, the water passing hole is formed on the peripheral surface of the micro filter 30 and the filter screen is disposed around the water passing hole, and the bottom of the micro filter 30 is disposed in a disc shape and provided with the second drainage hole 33, it can be understood that the residue can not pass through the filter screen but can pass through the second drainage hole 33 and the first drainage hole 114. During the washing process, the blocking cover 80 closes the second water discharge hole 33 to prevent the residue from flowing to the water returning gap 40 through the second water discharge hole 33 and finally flowing into the washing pump to contaminate the washing pump. In the draining process, the blocking cover 80 opens the second drain hole 33 to allow the residue to flow to the first drain hole 114 through the second drain hole 33 and finally to be discharged out of the dishwasher, and in this process, the residue does not enter the washing pump because the washing pump does not work, thereby effectively reducing the pollution to the washing pump. The blocking cover 80 may open or close the second water discharge hole 33 by applying an external force by a human, or may automatically open or close the second water discharge hole 33 by a buoyancy or a water flow pressure during washing or draining.

The water cup 10 component of the utility model is provided with the blocking cover 80 at the second drain hole 33 of the micro-filter 30, and the blocking cover 80 can close the second drain hole 33 in the washing process of the dish washer, so as to prevent the residue in the micro-filter 30 from entering the water return gap 40 from the second drain hole 33 and further entering the washing pump to cause pollution; during the draining process, the blocking cover 80 opens the second drain hole 33 to allow the residue in the micro-filter 30 to flow out from the second drain hole 33 and further to be discharged out of the return water chamber 11 from the first drain hole 114, thereby reducing contamination of the washing pump.

further, as shown in fig. 11 to 13, the blocking cover 80 is provided under the micro filter 30, and the blocking cover 80 may be lifted by buoyancy to close the second water discharge hole 33. In the present embodiment, the density of the capping 80 is less than that of water, that is, the capping 80 floats upward in water, and the capping 80 is disposed below the micro-filter 30, that is, below the second water discharge hole 33, so that the capping 80 floats upward by buoyancy to close the second water discharge hole 33. It can be understood that, in the washing condition of the dishwasher, before the water in the water return chamber 11 is pumped by the washing pump, the water is always present at the bottom of the water return chamber 11 and the liquid level is kept higher than the second water drainage hole 33, i.e. the blocking cover 80 keeps closing the second water drainage hole 33 under the action of buoyancy; in practical applications, the position of the water outlet 111 of the water return chamber 11 is higher than the second water discharge hole 33, so as to prevent the liquid level from being lower than the second water discharge hole 33, which results in that the height of the blocking cover 80 is not enough to close the second water discharge hole 33. In the drainage condition of the dishwasher, the first drainage hole 114 is lower than the second drainage hole 33, the water in the water return chamber 11 flows downward to the first drainage hole 114 as a whole, the downward flowing water forms a downward acting force on the blocking cover 80, the acting force is greater than the buoyancy of the blocking cover 80 in the water, therefore, the blocking cover 80 descends to open the second drainage hole 33, and the residue in the micro-filter 30 flows out of the first drainage hole 114 along with the water flow and directly flows to the first drainage hole 114, and is finally discharged from the first drainage hole 114. Therefore, the blocking cover 80 can automatically close the second drain hole 33 under the action of buoyancy under the washing working condition, and automatically open the second drain hole 33 under the drainage working condition, so that the discharge of residues is effectively controlled, and the practicability of the water cup 10 assembly is improved.

Further, as shown in fig. 11 to 13, a limiting post 34 is disposed at the bottom of the micro filter 30, the limiting post 34 protrudes downward from the bottom surface of the micro filter 30, the second drainage hole 33 is adjacent to the limiting post 34 and extends along the circumferential direction of the limiting post 34, and the blocking cover 80 is annularly disposed and sleeved on the limiting post 34. In this embodiment, the second drainage hole 33 extends around the limiting column 34, the inner wall of the second drainage hole 33 and the outer peripheral wall of the limiting column 34 are connected with a connecting rib, and the blocking cover 80 disposed annularly is sleeved on the limiting column 34, so as to limit the blocking cover 80 laterally. Because in the washing process, the washing pump can form horizontal suction to the water in the return water chamber 11, and shutoff lid 80 density is less, and the quality is less promptly, thereby for preventing that shutoff lid 80 from taking place the dislocation along lateral shifting along with rivers together, locate spacing post 34 with shutoff lid 80 cover, can effectively prevent shutoff lid 80 in the removal on transversely to make shutoff lid 80 close second wash port 33 steadily.

Further, as shown in fig. 11, the limit post 34 is connected to the bottom of the cup 10. In this embodiment, the position-limiting post 34 can be directly connected to the bottom wall of the cup 10, or can be indirectly connected to the bottom wall of the cup 10 through other structures. The limiting column 34 is connected to the bottom of the water cup 10, so that the blocking cover 80 can be prevented from being separated from the limiting column 34 after falling in the drainage process, the moving space of the blocking cover 80 is effectively limited, and the overall stability of the water cup 10 assembly is improved.

Further, as shown in fig. 11, the water cup 10 assembly further includes a rotating shaft 90 connected to the bottom of the water cup 10, a shaft hole 341 is formed on the lower end wall of the limiting column 34, and the rotating shaft 90 is rotatably matched with the shaft hole 341. In this embodiment, the position-limiting column 34 extends upward to increase the depth of the shaft hole 341, so as to increase the matching area between the rotating shaft 90 and the shaft hole 341 and improve the matching stability. The position-limiting column 34 is rotatably engaged with the rotating shaft 90, so that the entire micro filter 30 can be rotatably installed in the water return chamber 11 to realize the rotation of the micro filter 30 in the washing process.

further, as shown in fig. 11, a water passing groove 12 is concavely formed in the bottom of the water cup 10, the first drain hole 114 is opened in the bottom of the water passing groove 12, the rotating shaft 90 is connected to the bottom of the water passing groove 12, the bottom wall of the micro filter 30 is covered on the notch of the water passing groove 12, and the blocking cover 80 is located in the water passing groove 12. In this embodiment, a first cavity 115 of the water returning cavity 11 is formed on the upper side of the notch of the water passing groove 12, a second cavity 116 of the water returning cavity 11 is formed on the lower side of the notch of the water passing groove 12, the micro filter 30 is installed in the first cavity 115, and the second drain hole 33 is opposite to the notch of the water passing groove 12. It should be noted that, since the water outlet 111 is opened on the side wall of the water return chamber 11, the position of the water outlet 111 is higher than the notch of the water passing tank 12, that is, during the washing process, water is always kept in the water passing tank 12, so that the blocking cover 80 in the water passing tank 12 always keeps a state of floating on the notch of the water passing tank 12, that is, always keeps a state of closing the second water outlet 33 at the notch of the water passing tank 12, thereby enabling the blocking cover 80 to close the second water outlet 33 more stably during the washing process. In practical application, the edge of the notch of the water passing groove 12 preferably extends upwards to form a water blocking boss 122, and the upper end of the water blocking boss 122 abuts against the bottom end of the micro-filter 30, so that the liquid level in the water passing groove 12 is closer to the second water drainage hole 33 at the bottom of the micro-filter 30, the second water drainage hole 33 is closed more effectively by the blocking cover 80, the contact area between the bottom of the micro-filter 30 and the bottom of the water return cavity 11 can be reduced, the friction resistance of the rotation of the micro-filter 30 is reduced, and the rotation of the micro-filter 30 is smoother.

Further, as shown in fig. 11, a drain groove 121 is formed at the bottom of the water passing groove 12, the rotating shaft 90 is connected to the bottom wall of the drain groove 121, and the first drain opening is formed in the side wall of the drain groove 121. In this embodiment, the water passing groove 12 and the drainage groove 121 together form the second cavity 116, and the first drainage hole 114 is opened on the side wall of the drainage groove 121 to vacate the bottom wall of the drainage groove 121 and provide an installation space for the rotating shaft 90. The drain groove 121 can provide more water passing space between the first drain hole 114 and the second drain hole 33 so that the residue can more sufficiently flow out of the second drain hole 33 with the water flow.

Further, as shown in fig. 11, the first drain hole 114 penetrates the bottom wall of the water passing groove 12 to communicate with the water passing groove 12. In this embodiment, the first drainage hole 114 is opened on the side wall of the drainage groove 121 and extends along the transverse or inclined direction to form the drainage channel 200, and one end of the drainage channel 200 close to the drainage groove 121 is located below the bottom wall of the water passing groove 12, so that the drainage channel 200 can pass through the bottom wall of the water passing groove 12 upwards to be directly communicated with the water passing groove 12, thereby preventing the blocking cover 80 falling in the drainage process from covering the notch of the drainage groove 121 to cause the water to be discharged normally, and improving the drainage stability of the assembly of the water cup 10.

Further, as shown in fig. 11-13, the water cup 10 assembly further includes a drain pump 100 in communication with the first drain hole 114. In the present embodiment, the drainage pump 100 is used to draw water out of the first drainage hole 114 during drainage, thereby improving drainage efficiency. And at the same time, the drain pump 100 is operated to form a negative pressure in the bottom of the return water chamber 11, which is directed downward as a whole, so that the blocking cover 80 is lowered more quickly to open the second drain hole 33.

In another embodiment of the present invention, as shown in fig. 14 to 16, the inner wall of the water return chamber 11 is protruded with a guide protrusion 110 toward the micro-filter 30 to guide the water flowing around the water return gap 40 to the outer peripheral wall of the micro-filter 30.

In this embodiment, the inner wall of the water return cavity 11 is provided with a water outlet 111, and when the washing pump sucks water in the water return cavity 11 through the water outlet 111, part of the water flow in the water return cavity 11 flows around the water return gap 40 to form a vortex, which may be caused by the rotation of the micro filter 30 or the opening direction of the water outlet 111. The flow of water around the return water gap 40 is generally tangential to the outer peripheral wall of the microfilter 30 and does not cause effective impact on the outer peripheral wall of the microfilter 30. The guide protrusion 110 is located in the water return gap 40, the water flowing around the water return gap 40 changes the flow direction when flowing through the guide protrusion 110, and at least part of the water flowing in the changed flow direction acts on the outer peripheral wall of the micro-filter 30, so that impact is caused on the filter screen of the micro-filter 30 to wash residues attached to the filter screen, and the micro-filter 30 is cleaned. The cross-sectional shape of the guide protrusion 110 may be triangular, trapezoidal, or rectangular, and the like, and it is only necessary to guide the water flowing around the return water gap 40 to the outer circumferential wall of the micro filter 30. The protruding 110 quantity of water conservancy diversion can be a plurality of, and a plurality of protruding 110 circumferential interval settings that can follow return water chamber 11 inner wall of water conservancy diversion to at a plurality of positions with rivers direction microfilter 30 different positions on the circumference, increase the area of washing to microfilter 30, thereby improve the cleaning performance.

In practical applications, the guide vane 31 for assisting the rotation of the micro filter 30 is disposed on the outer peripheral wall of the micro filter 30, and since the guide vane 31 is also disposed in the water return gap 40, in order to prevent the guide projection 110 from obstructing the rotation of the guide vane 31, the guide projection 110 should be disposed below the guide vane 31.

The utility model discloses the drinking cup 10 subassembly sets up water conservancy diversion arch 110 through the inner wall at return water chamber 11 to the periphery wall of rivers direction micro filter 30 that will flow around return water clearance 40, from this, can make rivers impact micro filter's periphery wall, and wash the residue on the filter screen of micro filter 30, so that to micro filter 30's clearance, thereby need not set up in addition force (forcing) pump 50 and can wash micro filter 30, simplified dish washer's overall structure.

Further, as shown in fig. 16, the guide protrusion 110 includes a guide surface 120 facing the water flow direction of the water return gap 40, and the guide surface 120 extends from the inner wall of the water return cavity 11 to the micro-filter 30, so that the distance between the guide surface 120 and the outer wall of the micro-filter 30 is gradually decreased to increase the flow velocity of the water flow passing through the area surrounded by the guide surface 120 and the micro-filter 30.

In this embodiment, the diversion surface 120 faces the direction of the water flowing through the diversion protrusion 110, and the diversion surface 120 extends obliquely from the inner side wall of the cup 10 toward the direction close to the micro-filter 30, so that an obtuse angle is formed between the direction of the water flowing through the diversion surface 120 and the extending direction of the diversion surface 120, thereby preventing the kinetic energy of the water from being reduced after the water changes the flowing direction through the diversion surface 120, that is, ensuring that the water after changing the flowing direction can keep enough kinetic energy to wash the micro-filter 30, and improving the cleaning effect of the micro-filter 30.

Further, as shown in fig. 16, the flow guiding surface 120 is disposed in an inwardly concave arc surface. In this embodiment, the flow guiding surface 120 disposed on the concave arc surface enables the flow direction of the water flow to be changed more naturally and smoothly, so as to further reduce the kinetic energy loss of the water flow in the process of changing the flow direction, thereby further improving the cleaning effect of the micro-filter 30.

further, as shown in fig. 16, the flow guiding protrusion 110 further includes a connection surface 130 connecting the flow guiding surface 120 and the inner wall of the water returning cavity 11, and the flow guiding surface 120 and the connection surface 130 are clamped to form a flow guiding angle. In the embodiment, the flow guiding protrusion 110 is formed by clamping the flow guiding surface 120 and the connecting surface 130, so as to reduce the overall volume of the flow guiding protrusion 110, thereby reducing the space occupation of the flow guiding protrusion 110 on the water returning gap 40. The diversion plane 120 and the connection plane 130 form a diversion angle, which can increase the flow rate of the water flow changing after flowing through the diversion angle, i.e. increase the flow rate of the water for washing the micro-filter 30, so as to further improve the cleaning effect of the micro-filter 30.

further, the distance between the diversion angle and the peripheral wall of the micro-filter 30 is more than 0mm and less than or equal to 5 mm. In the embodiment, the width of the water return gap 40 is generally 10mm, and the flow rate of the water flow close to the micro filter 30 flowing around the water return gap 40 is faster, so that the distance between the diversion angle and the outer peripheral wall of the micro filter 30 is set to be greater than 0 and less than or equal to 5mm, the diversion angle can be closer to the micro filter 30, and thus the flow rate of the water flow after being changed by the diversion angle is faster, so that more kinetic energy impacts the micro filter 30, and the cleaning effect on the micro filter 30 is improved.

Further, a water outlet 111 is further formed in the side wall of the water return cavity 11, and the flow guide protrusion 110 is disposed adjacent to the water outlet 111. In this embodiment, the washing pump is communicated with the water outlet 111, and during the water outlet process, the flow velocity of the water flow near the water outlet 111 is larger, so that the flow velocity of the water flow which is changed to flow backwards by the flow guide protrusion 110 is correspondingly larger by arranging the flow guide protrusion 110 at the position near the water outlet 111, so that the kinetic energy of the water flow for washing the micro filter 30 is higher, and the washing effect on the micro filter 30 is further improved.

Further, the micro filter 30 may be rotatably installed in the water return chamber 11. In this embodiment, the water in the water return cavity 11 may form a vortex flow around the water return gap 40 during the water outlet process, and the water flow that is changed by the guide protrusion 110 to flow to the back-washing micro-filter 30 may also promote the rotation of the micro-filter 30 when hitting the micro-filter 30, so long as the changed water flow direction deviates from the axis of the micro-filter 30. The rotatable microfilter 30 can change the position opposite to the guide protrusion 110 during the rotation process, so that the changed flow direction can wash more parts of the microfilter 30, and the washing area of the microfilter 30 is increased, thereby improving the whole washing effect of the microfilter 30.

Further, as shown in fig. 16, the opening direction of the water outlet 111 is tangential to the outer peripheral wall of the micro filter 30. In this embodiment, the opening direction of the water outlet 111 is tangential to the outer peripheral wall of the micro filter 30, which can increase the flow potential of the water flow forming a vortex around the water return gap 40 during the water outlet process, thereby increasing the flow velocity of the water flow forming the vortex, so as to increase the flow potential of the water flow after the flow direction is changed by the flow guide protrusion 110.

Further, the connection surface 130 extends from the inner wall of the water return chamber 11 to the micro-filter 30, so that the distance between the connection surface 130 and the outer side wall of the micro-filter 30 is gradually reduced. In this embodiment, the connection surface 130 may be an inclined plane symmetrical to the diversion surface 120 about the central line of the diversion angle, so that the connection surface 130 can also play a role in diversion under the condition that the direction of the vortex formed by the water flow is opposite, that is, the application condition of the diversion protrusion 110 is reduced, and the overall practicability of the water cup 10 is improved. In practical application, the direction of the water flow forming the vortex is related to the opening direction of the water outlet 111 and the inclination direction of the flow deflector 31 on the micro-filter 30, and the connecting surface 130 is set to be an inclined surface capable of guiding the flow, so that the requirements on the opening direction of the water outlet 111 and the inclination direction of the flow deflector 31 in the production process can be reduced, and the production of the water cup 10 assembly is facilitated. In the production process, the flow guide bulge 110 and the water cup 10 are integrally arranged, so that the processing procedures are reduced, and the production efficiency is improved.

In this embodiment, the first drainage hole 114 can be opened on the bottom wall of the cup 10, or on the lower end of the sidewall of the cup 10, so long as the water on the bottom of the cup 10 can be completely drained through the first drainage hole 114. The drainage passage 200 is preferably formed at an angle of 15 to 90 degrees with respect to the horizontal plane so that water in the drainage passage 200 can flow downward by gravity. In order to reasonably utilize the space below the bottom plate of the liner and reduce the overall height of the assembly of the cup 10, the end of the drainage channel 200 away from the first drainage hole 114 can be located on one side of the assembly of the cup 10, thereby improving the space utilization below the bottom plate of the liner, i.e., on one side of the assembly of the cup 10.

The water cup 10 of the utility model is provided with the drainage channel 200 inclining downwards, so that the phenomenon that the dish washing water flows back to the bottom of the water cup 10 to cause the residue of the dish washing water in the water cup 10 due to the incomplete drainage of the drainage channel 200 is avoided, and the user experience is improved; in addition, the drainage channel 200 extends obliquely downward rather than vertically, so that the overall height of the cup 10 can be reduced, and the lateral space at the periphery of the cup 10 can be effectively utilized, thereby enabling the overall structure of the cup 10 to be more compact and the space utilization rate of the installation space of the whole dishwasher to be higher.

Further, as shown in fig. 17 and 18, the water cup 10 has a water return chamber 11, and the first drain hole 114 is opened in a side wall of the water return chamber 11.

The first drain hole 114 is opened at the side wall of the return water chamber 11 such that the opening direction of the first drain hole 114 is oriented in the lateral direction, thereby allowing the drain passage 200 to be connected to the side wall of the return water chamber 11, reducing the total height of the drain passage 200 and the cup 10, and thus reducing the overall height of the assembly of the cup 10.

further, as shown in fig. 17 and 18, the water return chamber 11 includes a first chamber 115 and a second chamber 116 recessed from a bottom wall of the first chamber 115, and the first drain hole 114 is opened in a side wall of the second chamber 116. In this embodiment, when the dishwasher drains water, the water may flow through the second cavity 116 from the first cavity 115 and then be drained from the first drain hole 114, so that it is avoided that the water in the position far away from the first drain hole 114 in the return water cavity 11 is difficult to drain due to being too far away from the first drain hole 114, thereby promoting sufficient drainage.

Further, as shown in fig. 17 and 18, a lower edge of the first drain hole 114 is flush with a bottom wall of the second cavity 116. In this embodiment, the lower edge of the first drainage hole 114 is flush with the bottom wall of the second cavity 116, so as to prevent the water at the bottom of the second cavity 116 from being discharged normally, and further promote the sufficient discharge of the water.

Further, as shown in fig. 18, the junction between the drainage channel 200 and the bottom wall of the second cavity 116 is rounded. In this embodiment, since the lower edge of the first drainage hole 114 is flush with the bottom wall of the second cavity 116, the drainage channel 200 connected to the first drainage hole 114 is also flush with the bottom wall of the second cavity 116, and the drainage channel 200 is smoothly transited to the bottom wall of the second cavity 116 at the connection point, so that the water in the second cavity 116 can flow into the drainage channel 200 more fully and smoothly, and the full drainage of the water is further promoted.

Further, as shown in fig. 17 and 18, the water cup 10 assembly further includes a drain pump 100 in communication with the drain channel 200. In the present embodiment, the drainage pump 100 is used to draw water out of the first drainage hole 114 during drainage, thereby improving drainage efficiency.

Further, as shown in fig. 17 and 18, the drain pump 100 includes a pump housing 101, the pump housing 101 is opened with a water inlet 102 communicated with the drain channel 200, and a water retaining ring 103 adjacent to the water inlet 102 is protruded on an inner wall of the pump housing 101. The water inlet 102 is connected to the drainage channel 200, and the water retaining ring 103 extends along the circumferential direction of the water inlet 102 to reduce the backflow of water from the drainage pump 100 into the drainage channel 200, thereby improving the drainage stability.

Further, the drainage pump 100 includes a pump housing 101, the pump housing 101 is opened with a drainage outlet 104, and the drainage outlet 104 is opened at an upper end of the pump housing 101.
