Problems solved by technology

However, when the micro-filter rotates, the gap between it and other parts is too large and uncontrollable, so that the residue will pass through the gap, and the residue cannot be filtered effectively, resulting in secondary pollution and affecting the cleaning performance of the whole machine

Embodiment 1

[0066] refer to Figure 5 to Figure 7 and combine Figure 1 to Figure 4 , The microfilter 4 is divided into two structures, the outer casing and the inner filter mesh part, wherein the filter mesh part can rotate freely in the casing. At the joint between the shell and the filter screen, a groove such as an annular matching groove 51 is provided on the shell, and the filter screen has a convex hull. Such a connection structure can form a labyrinth, which can effectively prevent residues from flowing out and reduce the Less secondary pollution.

[0067] Wherein, the housing is clamped by the flat filter 2 and the bottom of the water cup 1, and no residue will flow out from here. In terms of technology, since the flat filter 2 and the cup 1 are connected by the cup 3, which is a structure composed of multiple parts, the gap between the microfilter 4 and the bottom of the flat filter 2 and the cup 1 is uncontrollable , and the use of this structure does not need to be affected...

Embodiment 2

[0069] refer to Figure 8 with Figure 9 The upper end of the microfilter 4 is provided with an annular structure such as a step 43. The step 43 can wrap the bottom of the flat filter 2 to form an "L"-shaped gap, so that the residue is difficult to flow out from the gap and reduces secondary pollution. The structure is simple, because only two parts are connected, the gap between the step 43 and the flat filter 2 is controllable, and the microfilter 4 can rotate smoothly and reduce the flow of residue by adjusting the gap.

Embodiment 3

[0071] refer to Figure 10 with Figure 11 , there is an annular structure on the handle cup 3, a structure is provided on the microfilter 4 to cooperate with the annular structure, and it rotates along the annular structure. Although the gap between the upper and lower ends of the structure is uncontrollable, the gap at the rotating place is controllable, and the residue It is not easy to flow out, effectively reducing secondary pollution.

Abstract

The invention discloses a filtering device for a washing machine and a washing machine provided with the filtering device. The filtering device for the washing machine comprises a water cup, a plane filter, a lifting cup and a micro filter, wherein the water cup is arranged on the bottom outer side of a liner of the washing machine; a water inlet channel is formed on the water cup; the plane filter is arranged on the bottom inner side of the liner of the washing machine; a mounting hole is formed in the plane filter; the upper part of the lifting cup is connected with the periphery of the mounting hole of the plane filter; the lower part of the lifting cup passes through the mounting hole, and is connected to the inside of the water cup; at least a part of the micro filter is arranged in the water cup, and the micro water cup is rotationally arranged on the outer side of the lifting cup in a sleeving way; a gap sealing structure is formed between the periphery of the upper end of the micro filter and the periphery of the mounting hole of the plane filter; the outlet of the water inlet channel is suitable for driving the micro filter to rotate. By adopting the filtering device for the washing machine, the gap sealing structure is matched with water current to drive the micro filter to rotate, and comprehensive flushing is performed, so that the filtering effect of the micro filter is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a filter device for a dishwasher and a dishwasher having the same. Background technique [0002] When the dishwasher in the related art is working, because of the suction effect when the washing pump works and the drain pump drains water, the dirt is very easy to stick to the microfilter, especially near the water inlet of the washing pump and the drain pump. The self-cleaning structure of the dishwasher filter system, when the dishwasher is filled with water, the water through the flat water inlet is sprayed onto the micro-filter, so that the micro-filter rotates continuously, so as to achieve the effect of cleaning the filter screen. However, when the microfilter rotates, the gap between it and other parts is too large and uncontrollable, so that the residue will pass through the gap, and the residue cannot be effectively filtered, thereby causing secondary polluti...
