Referring to fig. 1-4, a filter apparatus 10 according to an embodiment of the present invention is used in a dishwasher, the filter apparatus 10 includes a cleaning assembly 12 and a middle filter assembly 14, the middle filter assembly 14 includes an upper cover 141 and a middle filter screen 142, the middle filter screen 142 is connected to the upper cover 141 and forms a middle filter chamber 143 together, an opening 1422 communicating with the middle filter chamber 143 is formed at a top of the middle filter screen 142, the upper cover 141 is disposed at the opening 1422, the cleaning assembly 12 includes a motor 122 and a blade 124, the blade 124 is disposed in the middle filter chamber 143, a rotating shaft 123 of the motor 122 is connected to the blade 124 and the upper cover 141, and the motor 122 is configured to drive the blade 124 to rotate and the upper cover 141 to open and close the opening 1422.
According to the filtering device 10 of the embodiment of the invention, when a dish washer washes, the upper cover 141 closes the opening 1422, water flows into the middle filter cavity 143 through the middle filter screen 142, filter residues are blocked outside the middle filter screen 142, and when washing is finished, the motor 122 rotates the upper cover 141 to open the opening 1422 and drive the blades 124 to rotate, water flows into the middle filter cavity 143 from the opening 1422, flows outwards towards the middle filter cavity 143 under the drive of the blades 124, and backflushes the filter residues attached to the outer surface of the middle filter screen 142, and discharges the filter residues along with the water flow, so that manual cleaning of the middle filter screen 142 is not needed after washing is finished, and user experience is improved.
Specifically, in the illustrated embodiment, the middle filter 142 is cylindrical, and the rotation shaft 123 is located on the central axis X of the middle filter 142. Thus, when the rotating shaft 123 rotates, the blades 124 rotate around the central axis X of the middle filter screen 142, so that the water in the middle filter cavity 143 is more uniformly discharged from the middle filter screen 142 and the filter residues attached to the outer surface of the middle filter screen 142 are reversely cleaned, and the cleaning effect is better.
Referring to fig. 5-7, in some embodiments, the upper cover 141 includes a first cover 1411 and a second cover 1414, the first cover 1411 is fixedly connected to the rotating shaft 123 of the motor 122, the second cover 1414 is rotatably connected to the rotating shaft 123, and the rotating shaft 123 drives the first cover 1411 to rotate so that the first cover 1411 rotates relative to the second cover 1414 to open and close the opening 1422. In this way, driving the upper cover 141 to open and close the opening 1422 by the rotation shaft 123 is achieved in a relatively simple manner.
Specifically, the rotation shaft 123 drives the first cover 1411 to rotate, the second cover 1414 rotates under the action of friction force between the rotation shaft 123 and the second cover 1414, the rotation direction is the same as that of the first cover 1411, the rotation speed is smaller than that of the first cover 1411, so that the second cover 1414 also rotates relative to the first cover 1411, and the opening 1422 is opened and gradually increases; when the opening 1422 needs to be closed, the rotating shaft 123 drives the first cover 1411 to rotate, the rotating direction is opposite to the rotating direction of the first cover 1411 when the opening 1422 is opened, the second cover 1414 rotates under the action of friction force between the rotating shaft 123 and the second cover 1414, the rotating direction is the same as the rotating direction of the first cover 1411, and the rotating speed is smaller than the first cover 1411, so that the second cover 1414 also rotates relative to the first cover 1411, and the opening 1422 gradually reduces to be closed. Of course, in other embodiments, the position of the second cover 1414 may be fixed, with only the first cover 1411 rotating as the opening 1422 opens and closes.
Further, the opening 1422 is circular, and the first cover 1411 and the second cover 1414 each include a plurality of fan blades disposed at intervals and in a fan shape. In this way, the first cover 1411 is rotated relative to the second cover 1414 to better open and close the opening 1422. Preferably, the total area of the blades of the first cover 1411 and the total area of the blades of the second cover 1414 each occupy half of the area of the opening 1422. In this way, the degree to which the opening 1422 is opened is maximized.
In the embodiment of the present invention, the first cover 1411 includes a connection portion 1412 and three first blades 1413 uniformly spaced around the connection portion 1412, the second cover 1414 includes three second blades 1415 spaced, and when the opening 1422 is closed, the first blades 1413 and the second blades 1415 spatially seal the opening 1422, and the overlapping area of the two blades is the smallest. In the process of opening the opening 1422, the area range of overlapping one second fan blade 1415 with the corresponding one first fan blade 1413 is gradually increased, and when the opening 1422 is opened, the area range of overlapping one second fan blade 1415 with the corresponding one first fan blade 1413 is maximum.
Thus, when the opening 1422 is opened, the opening 1422 is uniformly distributed, and water flows can uniformly enter the middle filter cavity 143 from the opening 1422, so that the water distribution of each part of the middle filter screen 142 in flushing is uniform, and the flushing effect is better.
Of course, in other embodiments, the number of the first fan blades 1413 may be other numbers, such as 1, 2, 4. The number of second fan blades 1415 is identical to the number of first fan blades 1413.
In the illustrated embodiment, the second cover 1414 is located above the first cover 1411, a first stopper 1417 and a second stopper 1418 are provided on a lower surface of the second cover 1414, and a third stopper 1419 cooperating with the first stopper 1417 and the second stopper 1418 is provided on an upper surface of the first cover 1411. When the third stopper 1419 abuts against the first stopper 1417, the upper cover 141 opens the opening 1422, and when the third stopper 1419 abuts against the second stopper 1418, the upper cover 141 closes the opening 1422.
In this manner, the relative rotation angle of the first cover 1411 and the second cover 1414 is restricted so that the process of opening and closing the opening 1422 by rotating the first cover 1411 and the second cover 1414 is more controllable.
It will be appreciated that, in this embodiment, if the first limiting block 1417, the second limiting block 1418 and the third limiting block 1419 are not provided, when the upper cover 141 is turned to open the opening 1422 after the washing is finished, the first fan blade 1413 and the second fan blade 1415 relatively rotate until the opening 1422 is maximized, and then the relative rotation is continued, which results in that the opening 1422 gradually decreases again, and the flushing water flow from the opening 1422 into the middle filter chamber 143 is affected. When the opening 1422 is closed, the first fan blade 1413 and the second fan blade 1415 relatively rotate until the opening 1422 is closed, if a limiting block is not provided, the relative rotation angle of the first fan blade 1413 and the second fan blade 1415 is difficult to control, so that the opening 1422 is difficult to be well closed, and water flow can directly enter the middle filter cavity 143 from the opening 1422 during washing of the dish washer without being filtered by the middle filter screen 142, and the filtering effect is poor.
In the embodiment of the invention, a third limiting block 1419 is disposed on the same side of each first fan blade 1413, a first limiting block 1417 is disposed on one side of each second fan blade 1415, and a second limiting block 1418 is disposed on the other side. It will be appreciated that on the first cover 1411, the first stopper 1417 and the second stopper 1418 are alternately arranged at intervals. When the first cover 1411 rotates relative to the second cover 1414, the third limiting block 1419 moves between the first limiting block 1417 and the second limiting block 1418, when the opening 1422 needs to be opened, the third limiting block 1419 rotates towards the first limiting block 1417, when the third limiting block 1419 abuts against the first limiting block 1417, the opening 1422 is opened to the maximum state, and the first limiting block 1417 prevents the first cover 1411 from continuing to rotate relative to the second cover 1414, so that the opening 1422 is kept in the state of the maximum opening degree, and water flow can enter the middle filter cavity 143 from the opening 1422 to reversely wash the middle filter screen 142. When the opening 1422 needs to be closed, the third limiting block 1419 rotates towards the second limiting block 1418, when the third limiting block 1419 abuts against the second limiting block 1418, the opening 1422 is closed, and the second limiting block 1418 prevents the first cover 1411 from continuing to rotate relative to the second cover 1414, so that the opening 1422 is kept in a closed state, and the filtering effect is ensured.
In other embodiments, the first cover 1411 may be positioned above the second cover 1414, the lower surface of the first cover 1411 being provided with a first stopper and a second stopper, and the upper surface of the second cover 1414 being provided with a third stopper that cooperates with the first stopper and the second stopper.
Of course, in other embodiments, the number of the first limiting block 1417, the second limiting block 1418, and the third limiting block 1419 may be other numbers; the positions of the first stopper 1417, the second stopper 1418, and the third stopper 1419 may be located at other positions.
In some embodiments, a mounting hole 1416 is formed in the middle of the second cover 1414, a first annular boss 1416a is formed on the inner surface of the mounting hole 1416, a second annular boss 1232 is formed on the outer surface of the rotating shaft 123, the mounting hole 1416 is penetrated through the rotating shaft 123, the second annular boss 1232 is clamped between the top of the mounting hole 1416 of the first annular boss 1416a, and the top of the mounting hole 1416 and the first annular boss 1416a cooperate to limit the movement of the second cover 1414 in the axial direction of the rotating shaft 123. In this way, the second cover 1414 is rotatably coupled to the rotation shaft 123 in a simple and stable manner.
Specifically, the mounting hole 1416 is a blind hole, and the second cover 1414 is carried on the rotation shaft 123 through the top of the mounting hole 1416, so that the mounting of the second cover 1414 is more stable.
Further, the first and second covers 1411 and 1414 are detachably coupled to the shaft 123, which facilitates removal of the cleaning assembly 12, and cleaning or maintenance of the cleaning assembly 12. In the embodiment of the invention, the connecting portion 1412 is provided with a connecting hole 1412a, a plurality of clamping grooves 1412b are uniformly distributed along the circumferential direction of the inner wall of the connecting hole 1412a, a plurality of protruding blocks 1234 respectively corresponding to the plurality of clamping grooves 1412b are formed on the outer surface of the rotating shaft 123, the rotating shaft 123 is provided with the connecting hole 1412a in a penetrating way and the protruding blocks 1234 are clamped in the clamping grooves 1412b, thus the horizontal movement of the first cover 1411 can be limited, the first cover 1411 synchronously rotates along with the rotating shaft 123, and the connecting way also facilitates the disassembly and assembly of the first cover 1411 and the rotating shaft 123. Of course, in other embodiments, the first cover 1411 and the shaft 123 may be detachably connected by other connection methods, such as a threaded connection, a snap connection, or the like. The plurality of bumps 1234 and the second annular boss 1232 are disposed at intervals along the axial direction of the rotating shaft.
