Detailed ways

A dishwasher filter structure according to the present invention includes a coarse filter 1 and a fine filter 2, the coarse filter 1 is arranged inside the fine filter 2, and the filter screen of the coarse filter is arranged at On the upper part of the fine filter, the bottom of the coarse filter 1 is connected with the bottom of the fine filter 2, and the bottom of the fine filter 2 is provided with a first drain hole 3 that communicates with the dishwasher drain pipe. It can effectively prevent food residues from escaping from the filter, and is convenient for collecting and cleaning food residues. At least part of the bottom of the fine filter 2 is a closed structure, and the filtered residue can be completely collected into the fine filter 2, and the residue will not stick to the water tank at the bottom of the fine filter 2. After the user takes out the filter, the residue is poured out. Go, no more cleaning the sink.

A fine filter screen 4 is provided on the circumferential side wall of the fine filter 2, the bottom of the fine filter 2 is a plate-like structure, and the center of the plate-like structure is provided with a first drain hole 3 that communicates with the dishwasher drain pipe. The water entering the fine filter 2 is filtered by the fine filter screen 4 to intercept the residue into the interior of the fine filter 2, and the plate-like structure isolates the residue from the water tank at the bottom of the fine filter, so that the residue does not stick to the water tank. , the user can clean the residue inside the filter after taking out the filter, no need to clean the sink, and it is easy to clean.

A coarse filter screen 5 is arranged on the circumferential side wall of the coarse filter 1 , and a through hole 6 communicated with the fine filter 2 is arranged at the bottom of the coarse filter 1 . The water in the dishwasher flows from the outside of the coarse filter 1 to the inside of the coarse filter 1 through the coarse filter screen 5, and the large residues are intercepted by the coarse filter screen 5 to the outside, and the smaller residues enter the inside of the coarse filter 1. It enters into the fine filter 2 through the through hole 6 which is communicated with the fine filter at the bottom of the coarse filter 1 . The through hole is larger than the smaller residue to ensure that the smaller residue can pass through the through hole, and the through hole is smaller than the area of the bottom of the coarse filter, which can effectively prevent the backflow of the smaller residue. Preferably, the through hole is semicircular. .

A plane filter screen 7 is arranged around the coarse filter 1 , and the intersection of the plane filter screen 7 and the coarse filter 1 is lower than the coarse filter screen 5 of the coarse filter 1 . Placing a plane filter screen 7 around the coarse filter 1 can largely divide the flow and filtration, and can solve the problem that only the coarse filter 1 and the fine filter 2 are installed at a slow filtration speed and are easily blocked. The plane filter screen 7 is set to be inclined The coarse filter screen 5 is lower than the coarse filter screen 1, which can ensure that a part of the water flow will enter the coarse filter screen 1 through the coarse filter screen 5, and then be filtered by the fine filter screen 2. The residue can also be collected in the plane filter screen 7 near the coarse filter screen 5, and the user can focus on cleaning these larger residues when cleaning.

A first water tank 9 is provided below the fine filter 2, the bottom of the first water tank 9 is provided with a second drain hole 15 corresponding to the first drain hole 3, and a second water tank 8 is provided under the flat filter screen 7. An opening 10 communicated with the circulation pipeline of the dishwasher is provided at the transition between the first water tank 9 and the second water tank 8 . The bottom of the fine filter 2 of the plate-like structure isolates the residue from the first water tank 9 at the bottom of the fine filter 2, so that the residue will not stick to the first water tank 9, and the second drain hole 15 is connected to the dishwasher. on the drain line.

The second water tank 8 provided under the flat screen 7 is higher than the first water tank 9 under the fine filter, the second water tank 8 is connected with the first water tank 9 under the fine filter, and the two are smoothly transitioned, even if When the residue enters the water tank, it will flow out with the flushing of the water flow to ensure that the residue will not accumulate. Preferably, the transition between the first water tank 9 and the second water tank 8 is provided with an opening 10 that communicates with the circulation pipeline of the dishwasher. Part of the water passes through the plane filter 7 and enters the second water tank 8 through the opening to enter the circulation pipeline to form a circulation, and a part of the water passes through the coarse filter 1 and the fine filter 2 and then enters the circulation pipeline through the opening to form a circulation.

The coarse filter 1 is connected to the fine filter 2, and the fine filter 2 is connected to the first water tank 9. Preferably, the bottom of the coarse filter 1 is provided with a downward protruding claws. The inner side of the bottom of the water tank is provided with a clamping groove, the clamping claw extends into the fine filter and is clamped with the clamping groove, the bottom of the water tank is provided with an upwardly protruding clamping claw, and the outer side of the bottom of the fine filter is provided with a clamping groove. The clamping claw is clamped with the clamping slot. The coarse filter and the fine filter are connected as a whole, and the coarse filter and the fine filter can be removed as a whole for cleaning.

The bottoms of the coarse filter 1 and the fine filter 2 are connected with the bottom of the first water tank 9. The bottom of the first water tank 9 is provided with a claw 11 extending upward, and the bottom of the coarse filter 1 is provided with downward. The protruding legs 12 have a gap 13 at the bottom of the fine filter 2 , the claws 11 extend into the fine filter 2 through the gap 13 , and the legs 12 abut against the bottom of the fine filter 2 and the claws 11 snap. The outriggers 12 and the claws 11 are clamped together to connect the three together.

The dishwasher with the above-mentioned filter structure of the present invention is provided with the above-mentioned filter structure at the bottom of the inner tank. During operation, a part of the water flow is filtered by the flat filter screen and then enters the circulation pipeline through the opening and enters the circulation system, and the other part passes through the coarse filter screen. 5. After filtration, it enters into the coarse filter 1, and then passes through the fine filter 4 and enters the circulation pipeline through the opening 10 to enter the circulation system, which is actually a partial filtration system. If all the water flows through the fine filter screen, it is easy to cause blockage, so in the present invention, part of it passes through, and the other part directly passes through the flat filter screen and then enters the circulation pipeline. More than half a meter per second, there will be no residue left on the lower part of the flat filter screen. In addition, it is washed by the nozzle at the bottom of the sprinkler. The filter is close to the coarse filter. The bottom of the fine filter is a closed structure except for the first drainage hole, the connection slot and the connection gap, which can completely collect the filtered residue into the fine filter, and the residue will not stick to the water tank at the bottom of the fine filter. , the user takes out the filter and dumps the residue away without cleaning the sink.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, various modifications and improvements can be made without departing from the principles of the present invention, which should also be regarded as the present invention. the scope of protection of the invention.
